The total early-stage entrepreneurial activity (TEA) in South Africa is said to be extremely low compared to those of other sub-Saharan countries. This is despite the concerted efforts of the government to establish, develop and nurture entrepreneurship at all levels, especially among the youths. This calls for concern given the current state of the economy and the challenges faced by South Africa’s future generation. This paper is anchored on two theoretical frameworks to substantiate our argument for the inclusion (...) of entrepreneurship education in the curricula of non-business programmes at universities of technology. The theoretical frameworks are the contingency organizational theory and the magnet versus radiant model. The study adopted an exploratory cross-sectional research design which allowed us to collect data from a cross-section of a population: the universities of technology in South Africa. The findings suggest that only fifteen (out of the 46) of the programmes showed visible evidence of entrepreneurship/business studies in their content. Such finding implies that there is a need for entrepreneurship to be integrated into the curricula of all non-business departments if not for the sake of its perceived employment generation attributes, but for its other attributes such as innovation, and more importantly employability.

Using research grants administrators and their clients (academic researchers) as the lens, this paper investigated the relevance and implication of a fraud prevention policy at a University of Technology (UoT) in South Africa. The paper adopted a quantitative approach in which closed-ended questions were complemented by open-ended questions in the survey questionnaire in the attempt to capture the perceptions of both research grants administrators and their clients on the relevance and implications of a fraud and irregularity prevention policy. (...) The results indicate that both research grants administrators (71.4 %), and their clients (73%) do not know if UoTx has a fraud and irregularity policy. While only 36% of research grants administrators indicated that they would feel safe reporting deceitful activities, a slight majority (59%) of the clients reported same. With regards to the steps to follow to report fraudulent activity, it was noted that while all (100%) the research grants administrators noted that they were clueless, ironically an overwhelming majority of their clients indicated otherwise. Notwithstanding, both research grants administrators and their clients (93% and 95% respectively) concurred that a fraud prevention policy was necessary for UoTx. The implication is that having phenomenal controls that are not effectively publicized, monitored or worse still overridden by someone are useless. (shrink)

This paper will reflect on the possibility of epistemic decolonization, particularly in terms of curriculum, as a transformative educational process in the context of the South African university, and with respect to my own positionality. The argument will centre around two difficult interdependent positions. On the one hand I will argue for the university’s task as transformational, even offering, via Cornel West, the ‘salvific’ possibility that knowledge offers those who seek it. To develop this claim, I will draw (...) on and develop the notion of paideia though the work of Plato and Heidegger.On the other hand, within the postcolonial African university, the question of decolonization in the tertiary space cannot be elided, particularly since the 2015 #RhodesMustFall and #FeesMustFall movements. The university is a powerful colonial relic, and it can be used to reinforce and perpetuate epistemic violence through unreflective or unconscious pedagogical and curriculum decisions. Here I draw on decolonial thinkers such as Santos, Mignolo, Maldonado-Torres, and Mbembe: I argue for a reckoning with the forces of coloniality, and advocate for epistemic justice and criticality, as part of the decolonizing project. In conclusion, working with ideas from Cornel West, I argue to reconcile paideia, as the ‘turning of the soul’, with the decolonizing African university. (shrink)

in academic entrepreneurship and creation of university spin-off companies has grown in South Africa. This study aims to establish the factors that inspire academics to engage in entrepreneurial activities and to identify the role that academic entrepreneurs play in the process of technology transfer and commercialization at University of Technology (UoT) X. A quantitative research approach is adopted throughout this study. As part of the quantitative research approach, structured questionnaires were directly administered to the respondents to collect (...) the data. Specifically, 52 electronic survey questionnaires were distributed. The sample is drawn from two databases compiled, using UOTX’s internal research records. One of the databases, held a list of those academics who have been active in terms of research as evident in their research outputs – technology creation and transfer. The other database (control group) holds a list of those academics that have not been active. From both groups, a purposive sample is drawn for the survey questionnaire. This study notes that pull factors tend to influence the entrepreneurial activities of academics at UOT X more than push factors and that academics are key players in the process of technology transfer. Thus, this study may assist the university senior management to develop strategies to improve academic entrepreneurship for all faculties. In line with this, it is expected that the primary function of UOT X should be to instil a greater entrepreneurial spirit among the relevant stakeholders. (shrink)

Going by the assumption that technology is not created for its own sake, this paper gauges the peculiar role that of spin-off, and private companies play in the process of technology creation and transfer at a University of Technology (UoT) in South Africa, using academic entrepreneurs as the lens. Structured questions were electronically administered to the 52 participants purposively drawn for the study. The sample was drawn from a database composed using UoT X’s in-house research records. (...) Included in the database, were active and non-active academics in terms of technology creation and transfer. It was noted that most active researchers and innovators were involved in one form of university–industry collaboration or another. Furthermore, it was observed that the private companies had a vital role to play as far as the process of technology transfer and commercialization is concerned. This is notably relevant given that the overwhelming majority of the participants (91.7%) reiterated the importance of university–industry partnerships in the transfer and commercialization of inventions. Moreover, highlighting the importance of private companies, a slight majority (52.8%) of the participants indicated that they were surely motivated to bring forth innovative products by private companies in the last five years.

Globally, digital disruption has accelerated in the last few years. It is argued that this technological revolution would fundamentally alter our interactions with one another, our work, and our lives. The Fourth Industrial Revolution (4IR) can blur the boundaries between the physical and biological worlds. Although the extent of the effect is unclear, many anticipate massive changes in the economic and educational spheres. Given the close relationship between the economy and the drivers of entrepreneurship in universities, the survival of (...) entrepreneurial universities remains contingent on the influence and preparedness of the 4IR. This review aimed to ascertain South African entrepreneurial universities’ readiness for the 4IR. Systematic literature analysis was adopted for this study; it draws on journal articles, books as wells as online publications relating to disruptive innovation, entrepreneurial universities and 4IR. The paper argues that there is a need for a radical overhaul of the current curriculum, as retraining lecturers to prepare for 4IR disruptions. (shrink)

I critically examine the South African university student and worker protests of 2015/2016 in light of moral principles governing the use of force that are largely uncontested in both the contemporary Western and African philosophies of just war, violence and threats. Amongst these principles are: “discrimination”, according to which force should be directed not towards innocent bystanders but instead should target those particularly responsible for injustice; “likely success”, meaning that, instead of being counter-productive, the use of force (...) must be reasonably expected to advance a just cause; and “last resort”, which entails that only the least force necessary to rebut injustice should be employed. I invoke these and related principles to appraise a wide array of types of student/worker protests, noting which of them accorded with the principles and which did not. I also reply to defences that some South Africans have recently made of protesting with coercion and destruction. (shrink)

Faced with enormous unemployment, the South African government enacted pro-SMME policies. It was assumed that such policies would ignite broad-based growth within the SMMEs cluster, regardless of the sector. However, the current evidence suggests that these laudable efforts have not benefited the poorest of the poor nor have they aroused and sustained entrepreneurship in certain quarters. Using the spaza shop as the focus and two prominent townships as the locus, this paper sought to understand the factors that under (...) mind the effective startup of businesses by natives. Furthermore, it identified the support structures that can foster and sustain new firm births. Leaning on the exploratory and descriptive research design, the quantitative research approach was enforced through self-administered questionnaires. The data collected was captured and analysed using the Statistical Package for the Social Sciences (SPSS) software, and was based on 121 fully completed questionnaires. A number of challenges unique to native spaza shops were conceded. These included a restricted access to seed capital, inability to benefit from bulk purchases, competition from non-South African shops, lack of business information, unsuitable business location, and the lack of collateral. The customarily challenges included a high level of crime, high cost of security and limited management skills. To encourage and sustain, new firm births, firstly, spaza shop-owners must have a clear vision of what they want to achieve before they embark on the venture. Secondly, crime must be dealt with collectively. Thirdly, government agencies and the private sector must come on board to address the skills gap. Lastly, technology should be adopted, to mitigate the issues around bulk purchases and transport costs. (shrink)

FISIOLOGIA DO PARTO E DA LACTAÇÃO ANIMAL -/- ANIMAL REPRODUCTION: PHISIOLOGY OF PARTURITION AND ANIMAL LACTATION -/- Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE WhatsApp: (82)98143-8399 -/- 1. INTRODUÇÃO O sucesso biológico do processo de reprodução culmina com a sobrevivência das crias. Durante a gestação, o feto desenvolve-se no útero materno protegido das influências externas, e obtendo os nutrientes e o oxigênio através da mãe. O parto é o processo biológico que marca o fim da gestação e (...) o início da vida extrauterina do animal. Para garantir a sobrevivência do recém-nascido o parto deve ser um processo controlado para que se inicie unicamente quando o feto tiver alcançado desenvolvimento suficiente que lhe permita enfrentar a vida extrauterina. Após o nascimento, a secreção de leite pela glândula mamária proporciona ao neonato tanto os nutrientes necessários para seu desenvolvimento como as defesas (imunoglobulinas) que lhe protegerão contra as possíveis infecções durante as primeiras fases de sua vida. Parto e lactação constituem a última etapa de um ciclo reprodutivo completo nas fêmeas dos animais domésticos, estando ambos os processos regulados e sincronizados por complexas mudanças hormonais na mãe. Estas mudanças são, em última análise, provocadas e governadas pelo próprio feto ou recém-nascido, o qual acomoda as respostas maternas às suas necessidades garantindo a sua sobrevivência. 2. O PARTO O parto é definido como o processo fisiológico pelo qual ocorre a expulsão de um ou mais fetos maduros, bem como das membranas fetais existentes no útero materno. Este processo é desencadeado por uma interação complexa entre as hormonas maternas (fatores maternos) e fetais (fatores fetais). Para que se realize a expulsão do feto é necessário que o útero deixe de ser um órgão quiescente, essencial para a manutenção da gestação, para ser um órgão contrátil. Ao mesmo tempo, o cérvix ou colo uterino, que durante a gestação permanece firmemente fechado para impedir a expulsão prematura do feto e evitar a entrada de agentes infecciosos, relaxa e dilata para facilitar a passagem do feto na hora do parto. Esta modificação na atividade do útero e do colo uterino, ocorrem como consequência das mudanças hormonais que o organismo materno experimenta à medida que a data do parto se aproxima. 2.1 Fatores maternos A gestação dos animais domésticos ocorre com elevada concentração de progesterona que, dependendo da espécie animal, é secretada seja pelo corpo lúteo do ovário (vaca, porca e cabra) ou pela placenta (ovelha e égua). A progesterona desempenha um papel fundamental durante a gestação, inibindo as contrações da musculatura lisa do útero (miométrio), permitindo assim a acomodação do feto durante o seu crescimento. Os estrogênios, estimulantes da atividade contrátil do miométrio, mantêm-se a baixas concentrações durante a maior parte da gestação. À medida que se aproxima o momento do parto, os níveis destes hormônios esteroides modificam-se, produzindo-se a diminuição nos níveis circulantes da progesterona ao mesmo tempo que se incrementam os valores sanguíneos dos estrogênios (figura 1). A redução dos níveis de progesterona suprime a sua ação inibitória sobre a atividade contrátil do miométrio, permitindo que se manifestem os efeitos estimulantes dos estrogênios sobre este órgão. A concentração de estrogênios começa a aumentar geralmente no final da gestação, atingindo os seus valores máximos no momento do parto (figura 1). O aumento da concentração de estrogênios favorece a atividade contrátil espontânea do útero ao: a) estimular a síntese de proteínas contráteis; b) aumentar, sob medida, a sensibilidade do miométrio uterino à ação estimulante das prostaglandinas; c) induzir a formação de receptores de oxitocina no útero. -/- Figura 1. Níveis de progesterona e estrógenos durante a gestação e parto das espécies ovina, caprina, suína e bovina. Fonte: HAFEZ, 2013. Os estrogênios estimulam a síntese e secreção de prostaglandina (PGF2a), que constitui o elemento essencial para o início do parto devido aos efeitos que esta substância provoca. Assim, nas fêmeas, cujos níveis de progesterona gestacional dependem da presença do corpo lúteo, a secreção de PGF, origina a regressão deste (luteólise), com a consequente diminuição da progesterona a níveis basais. Além disso, a PGF2a origina contrações de crescente intensidade no útero sensibilizado pela ação dos estrogênios. Esta ação contrátil da PGF2a deve-se a um aumento da concentração de cálcio intracelular das fibras musculares uterinas. A PGF2a também está envolvida no relaxamento do colo do útero, inibindo a formação de colágeno cervical ao mesmo tempo que estimula a síntese de enzimas (colagenase) que degradam a matriz de colágeno formado no início da gestação. A dilatação do colo do útero está também associada à pressão que o feto exerce sobre o mesmo e, no caso da porca, a relaxina pode também estar envolvida. Esta hormona é também de grande importância para a preparação do parto em todas as espécies animais, uma vez que é responsável pelo relaxamento dos ligamentos e músculos que rodeiam o canal pélvico para favorecer a separação da sínfise púbica durante a expulsão do feto. Nos grandes animais (vaca, égua) as mudanças que ocorrem nos tecidos e ligamentos pélvicos são muito evidentes e constituem um sintoma de parto iminente. O início do parto, ou primeira fase do parto, caracteriza-se pelo aumento das contrações uterinas provocadas pela PGF2a coincidindo com a dilatação do colo uterino para permitir a passagem do feto para o canal do parto, momento em que começa a segunda fase do parto. A distensão vaginal que produz-se para a passagem do feto pelo canal do parto origina um estímulo nervoso que viaja através da medula espinal para o hipotálamo, onde se encontram os neurônios responsáveis pela síntese de oxitocina. As terminações nervosas destes neurónios são projetadas para o lobo posterior da hipófise (neurohipófise), onde a oxitocina é secretada para ser, posteriormente , transportada pela circulação sanguínea. Este reflexo neuroendócrino chamado reflexo de Ferguson determina a secreção súbita de oxitocina, provocando o aumento tanto na intensidade como na frequência das contrações uterinas necessárias para a expulsão final do feto. O papel da oxitocina é ativar a conclusão do processo de expulsão, uma vez que esta hormona não está envolvida no início do parto. A alteração mais significativa entre a gestação e o parto é a alteração na atividade contrátil do miométrio uterino. Esta mudança é devido às alterações hormonais que ocorrem na mãe quando a gestação chegou a fim. No entanto, para que estes mecanismos maternos sejam acionados, é necessário que o feto indique de alguma forma à mãe o seu estado de desenvolvimento, de modo que o nascimento realize-se quando o feto estiver preparado para enfrentar a vida extrauterina. 2.2 Fatores fetais A destruição experimental da hipófise e/ou das glândulas adrenais do feto origina o prolongamento da gestação nos animais domésticos. Pelo contrário, a administração exógena de cortisol (corticosteroides adrenais), ou do seu precursor hipofisário (ACTH), à circulação fetal provoca, em poucas horas, o início do parto. Estes fatos evidenciam a importância do eixo hipófise-adrenal do feto para desencadear o início do parto (figura 2). Figura 2. Mecanismos fetais que controlam o parto em ovelhas. Fonte: LIGGINS et al, 1972. No final da gestação, o feto maduro apresenta um aumento da concentração de corticosteroides plasmáticos devido ao efeito estimulante da hormona adrenocorticotróide (ACVH) secretada pela hipófise fetal sobre as glândulas adrenais do feto. Os corticosteroides fetais por sua vez estimulam as enzimas placentárias para transformar a progesterona em estrogênio. O resultado final é a diminuição dos níveis de progesterona ao mesmo tempo que se eleva a concentração de estrogênios que, por sua vez, estimulam a libertação de PGF2a responsável pelas contrações uterinas. Este raciocínio explica algumas doenças caracterizadas por gestação prolongada em ovelhas, como ocorre na África do Sul, onde estes animais são obrigados, durante as épocas de seca, a ingerir as folhas de um arbusto chamado Salsola tuberculate. O prolongamento da gestação ocorre quando estas folhas são ingeridas durante o último terço da gestação cujos efeitos estão relacionados com a supressão do eixo hipotálamo-hipófise, com o qual as adrenais não recebem o estímulo necessário (ACTH) para a síntese e liberação de corticoides. O efeito contrário é observado nas cabras da raça Angorá, nas quais se produzem, com relativa frequência, partos prematuros que podem estar relacionados com um desenvolvimento precoce das glândulas adrenais. Isto significa que, nos animais domésticos, o feto determina a data do parto. O sinal hormonal que indica à mãe o grau de maturidade do feto é o desenvolvimento do eixo hipotálamo-hipófise-adrenal que origina o aumento na secreção de corticoides fetais que são os responsáveis por desencadear as alterações hormonais no organismo materno necessárias para iniciar o parto. A figura 2 mostra como a remoção da hipófise e as adrenais do feto prolongam a gestação, enquanto a administração exógena de ACTH ou corticoides (cortisol) ao feto originam um parto prematuro. O momento em que ocorre o aumento da concentração plasmática de corticoides no feto varia de acordo com a espécie: de 25 a 30 dias antes do parto na vaca, de 7 a 10 dias na porca e de 2 a 3 dias na ovelha. 2.3 Desenvolvimento e fases do parto O parto inicia-se com o início das contrações peristálticas e regulares do miométrio uterino ao mesmo tempo que o colo do útero se dilata progressivamente. Nas fêmeas que gestam um único feto (monotecas), as contrações começam na extremidade anterior do córneo uterino, enquanto que nas espécies que gestam vários fetos (politocas) as contrações começam pela extremidade cervical para começar a expulsar o feto que se encontra mais próximo do cérvix. Durante o parto são reconhecidas três fases: 1. Fase preparatória - Na qual as contrações uterinas estimulam a rotação do feto (fêmeas monotecas) para adotar a posição dorsal (extremidades anteriores e cabeça forçadas contra o cérvix) que lhe permite oferecer a menor resistência para sua expulsão. A PGF2a provoca as contrações miometriais e a dilatação do cérvix, deslocando o feto contra e através desta estrutura. 2. Fase de expulsão - A passagem do feto através do colo uterino e da vagina causam a completa dilatação destas estruturas, originando a secreção de oxitocina (reflexo de Ferguson), que provoca contrações de maior frequência e intensidade. Por sua vez, estas contrações uterinas são reforçadas pela pressão e contração dos músculos abdominais, chegando estes últimos a ser a força principal (forças de expulsão) envolvida no processo de expulsão do feto. O cordão umbilical rompe-se bem ao levantar-se a mãe ou pelos movimentos do recém-nascido. 3. Fase de expulsão da placenta - Após o parto, as contrações rítmicas do útero continuam a facilitar a expulsão da(s) placenta(s). O tempo necessário para este processo varia de acordo com a espécie animal. Este processo é rápido na égua, já que a separação do corion (membrana fetal) de sua inserção uterina ocorre durante a expulsão do feto, com o qual o parto deve ser concluído rapidamente ou, caso contrário, o potro se asfixiaria. Nos ruminantes, a expulsão da placenta cotiledonaria é um processo mais lento que exige a separação dos cotilédones (membrana fetal) das carúnculas do útero. Por conseguinte, a troca de nutrientes e oxigênio entre a mãe e o feto continua até que este tenha sido totalmente expelido, devido ao cordão umbilical destes animais ser bastante longo. Nas fêmeas politocas, como a porca, geralmente as placentas de vários leitões são expulsadas no final, quando os leitões já foram expelidos, se bem que o último leitão poderá ser expelido durante a expulsão da massa placentária. 3. LACTAÇÃO A lactação constitui o processo que define os mamíferos como classe biológica. O desenvolvimento pós-natal dos mamíferos vai depender, em grande medida, dos nutrientes e defesas fornecidos pela mãe através da secreção de leite (imunoglobulinas). Assim, uma vez concluído o desenvolvimento gestacional do feto, a glândula mamária irá substituir, de certa forma, a função nutritiva e protetora da placenta durante a gestação. 3.1 Anatomia funcional da glândula mamária A estrutura funcional da glândula mamária é muito semelhante em todos os mamíferos, embora o tamanho, forma e número de glândulas varia dependendo da espécie animal. As glândulas mamárias desenvolvem-se como estruturas pares cujo número varia de um par (égua, cabra e ovelha), dois pares (vaca) até sete ou nove (porca). A localização das glândulas também difere sendo inguinal em vaca, égua, cabra e ovelha, enquanto que na porca, cadela e gata se estendem por todo o comprimento do tórax e abdômen. Nos animais domésticos em geral as glândulas mamárias recebem o nome de úberes. Tomando como modelo a vaca, a glândula mamária se organiza em duas estruturas: o estroma, formado por tecido conjuntivo procedente dos ligamentos suspensório medial, localizado entre os dois pares de glândulas, dando suporte à segunda estrutura que é o tecido secretor. Este é formado por acúmulos de células secretoras formando estruturas ocas chamadas alvéolos, que são as unidades fundamentais secretoras de leite. Os alvéolos estão circulados internamente por células epiteliais (secretoras) e rodeados externamente por células mioepiteliais contráteis, cuja contração origina a ejeção do leite (figura 3). O agrupamento de vários alvéolos adjacentes formam um lobo secretor. Figura 3. Diagrama de um agregado de alvéolos na glândula mamária de uma cabra. Fonte: COWIE et al, 1980. Os lobos expelem a secreção através de ductos que, por sua vez, drenam os ductos galactóforas (ductos lácteos) de maior diâmetro, para desembocar em áreas especializadas em armazenar o leite chamadas cisternas (vaca, cabra). Finalmente, a cisterna abre-se para o exterior através do canal papilar da teta. A presença do músculo liso na teta permite-lhe agir como esfíncter para impedir que o leite seja expelido passivamente do interior da glândula. O mamilo/teta é provido de numerosos receptores sensitivos cuja excitação durante a ordenha ou amamentação vai desencadear estímulos nervosos de grande importância para a manutenção da lactação. 3.2 Desenvolvimento da glândula mamária (mamogênese) A glândula mamária difere das demais glândulas do organismo no escasso desenvolvimento que apresenta no nascimento da fêmea, o qual não se inicia até que esta não atinja a puberdade. O início da atividade cíclica do ovário (puberdade) dá origem à síntese de estrogênios (fase folicular do ciclo estral) e progesterona (fase lútea). Os estrogênios originam o alongamento e ramificação dos ductos e a formação de pequenas massas esféricas de células (os futuros alvéolos). Embora este desenvolvimento seja dependente do estrogênio, é também necessária a ação sinérgica da prolactina, hormona do crescimento (GH) e corticoides adrenais, como demonstrado pelos estudos realizados em ratos aos quais foi removida a hipófise, glândulas suprarrenais e ovários (figura 4). A função da progesterona no desenvolvimento da glândula mamária é estimular o crescimento do lobo-alveolar, mas como no caso anterior também requer a ação conjunta dos hormônios acima mencionados. Figura 4. Hormonas relacionadas com o crescimento da glândula mamária e início da secreção de leite na rata hipofisectomizada-adrenoectomizada-ovariectomizada. Fonte: COWIE, 1980. O desenvolvimento da glândula, durante cada ciclo estral, vai depender da duração da fase folicular (níveis elevados de estrogênio), já que nas restantes fases do ciclo, quando os níveis de estrogênio são baixos, os ductos sofrem uma ligeira regressão. Nas espécies com ciclos curtos (rata), em que a fase folicular do ciclo é predominante, enquanto a fase lútea é quase inexistente, verifica-se um grande desenvolvimento dos ductos; enquanto que aquelas que apresentam um corpo lúteo funcional de longa duração (cadela e primatas), além do crescimento dos ductos, mostram um grande desenvolvimento lóbulo-alveolar semelhante ao que ocorre na gestação. É durante a gestação que o sistema alveolar sofre uma hipertrofia considerável, resultando em lobos proeminentes e no desenvolvimento da luz interna dos alvéolos, fato que é evidente na maioria dos animais domésticos por volta da metade do período gestacional. Em algumas espécies, as células que circundam interiormente os alvéolos contêm produtos secretores, indicando que a glândula mamária já está preparada para a fase da lactação. O desenvolvimento glandular durante a gestação deve-se ao efeito conjunto da progesterona e dos estrogênios com as hormonas hipofisárias acima mencionadas: prolactina, hormona do crescimento (GH) e adrenocorticotropina (ACTH). A proporção entre estrogênios e progesterona varia de acordo com a espécie, mas geralmente é necessária uma maior concentração de progesterona (proveniente do corpo lúteo ou da placenta). Quanto às hormonas hipofisárias, a prolactina desempenha um papel fundamental na diferenciação da glândula mamária (mesmo a baixas concentrações) ao estimular o desenvolvimento do epitélio secretor dos alvéolos. A GH favorece o crescimento dos ductos e a ACTH estimula a secreção de corticoides nas adrenais que, por sua vez, favorecem de forma generalizada o crescimento das glândulas. 3.3 Secreção da glândula mamária (lactogênese) A lactogênese, ou o processo pelo qual se produz a síntese e secreção do leite pela glândula mamária, começa no final da gestação coincidindo com o desencadeamento do parto. O primeiro leite formado imediatamente antes ou depois do parto é denominado colostro. No entanto, a lactação não pode desenvolver- se completamente até que se inicie o processo de parto. Isto deve-se ao fato de que o processo de lactação resulta de uma interação complexa de hormonas que preparam a glândula mamária para a secreção do leite. Os requisitos hormonais mínimos para o início da lactogênese são: aumento da secreção de estrogênios, prolactina e corticoides, juntamente com a diminuição da concentração de progesterona, perfis hormonais que estão intimamente relacionados com o desencadeamento do parto. Isto deve-se ao fato de que a progesterona inibe a atividade lactogênica da prolactina bloqueando a formação dos seus receptores na glândula mamária durante a gestação impedindo, assim, a prolactina de sintetizar os componentes fundamentais do leite. Pelo contrário, o aumento da concentração de estrogênios no final da gestação (figura 1, na seção do parto) estimula a síntese, o armazenamento e a secreção hipofisária de prolactina. Assim, apesar da glândula mamária estar preparada para iniciar a secreção de leite, muito antes da data prevista para o parto, a elevada concentração de progesterona (existente durante esse período de gestação) impede a fase láctea (saída do leite pelas tetas) de ocorrer antes da expulsão do feto. Desta forma, o feto poderá beneficiar das vantagens que o fornecimento do colostro materno irá trazer para a sua sobrevivência (imunização, nutrição e favorecimento da exoneração do mecônio). O aumento da concentração de estrogênios nos dias que antecederem o parto resulta num rápido aumento das concentrações plasmáticas de prolactina e corticoides. A prolactina é a hormona lactogênica mais importante na síntese dos componentes do leite. No entanto, para que esta hormona possa exercer a sua função, é necessária a participação dos corticoides, já que os mesmos são os responsáveis pelo desenvolvimento das organelas citoplasmáticas (retículo endoplasmático rugoso e aparelho de Golgi) onde se realiza a síntese do leite. No desenvolvimento da lactogênese, para além da prolactina e dos corticoides, participam também outras hormonas como a insulina, a tiroxina e o hormônio do crescimento. A insulina estimula a proliferação de novas células epiteliais na glândula mamária, enquanto a tiroxina, embora não seja essencial para a lactação, pode influenciar no volume de leite produzido pela fêmea (alta produção leiteira). Por último, a hormona do crescimento favorece, em geral, a lactação, existindo atualmente um interesse considerável no uso desta hormona para promover a produção adicional de leite em vacas através da sua administração exógena (trabalho e projeto desenvolvido pela professora titular e médica-veterinária do IFPB Campus Sousa Marianne Christina Velaqua). 3.3.1 Síntese e secreção dos componentes do leite Os principais constituintes do leite são: proteínas (caseína, alfa-lactalbumina, albumina sérica e imunoglobulinas), açúcares (lactose), gorduras (principalmente sob a forma de triglicerídeos), vitaminas, minerais e citrato (no caso dos ruminantes). As proteínas (caseína e alfa-lactalbumina) são sintetizadas no retículo endoplasmático rugoso e posteriormente embaladas em vesículas secretoras do aparelho de Golgi para serem liberadas da célula para a luz alveolar mediante um processo de exocitose. A lactose é o principal açúcar do leite que, além disso, atua regulando a pressão osmótica do mesmo de modo que o volume de leite que a glândula mamária segrega está diretamente relacionado com a quantidade de lactose presente. A síntese da lactose ocorre no aparelho de Golgi pela condensação de glicose e galactose; esta reação é catalisada por uma enzima (lactose sintetase) presente na membrana do aparelho de Golgi que, por sua vez, é ativada pela proteína alfa-lactalbumina. Esta proteína só aparece na glândula mamária e é essencial para a síntese da lactose, o que demonstra que este açúcar é exclusivamente formado no leite. A lactose é também embalada junto com o cálcio, o fosfato e as proteínas nas vesículas secretoras para ser expulsada ao lúmen alveolar por exocitose. As imunoglobulinas (anticorpos IgA) são formadas pelas células plasmáticas, derivadas dos linfócitos B do sangue, como consequência da exposição da mãe a diferentes microrganismos. Estes anticorpos passam para a glândula mamária por migração dessas células a partir dos tecidos adjacentes. Os triglicerídeos são sintetizados no citoplasma e no retículo endoplasmático liso a partir de ácidos graxos provenientes da circulação sanguínea; em seguida, unem-se formando glóbulos de gordura que se dirigem até o vértice da membrana plasmática para serem finalmente expelidos para a luz do alvéolo, rodeados pela membrana, formando assim uma dispersão de glóbulos de gordura (figura 5). Figura 5. Estrutura de três células alveolares durante a síntese do leite. Fonte: COWIE, 1980. Do ponto de vista quantitativo, a caseína e os triglicerídeos constituem as proteínas e as fontes de energia, respectivamente, mais importantes do leite. Por último, o citrato é um intermediário do metabolismo da glicose que ocorre em grande concentração no leite dos ruminantes. Este composto é também englobado no interior das vesículas secretoras, junto com os outros compostos, para sua expulsão à luz alveolar. A composição do leite varia dependendo da espécie animal, e difere também até entre a mesma espécie. Estas variações estão relacionadas com a raça, idade, estágio de lactação e estado nutricional do animal. O teor de gordura no leite de ovelhas, porcas, cadelas e gatas varia entre 7 e 10%. No gado leiteiro estes valores variam de 3,5 a 5,5%, dependendo da raça. Em relação às cabras, os valores de gordura são muito semelhantes aos das vacas, enquanto o leite das éguas é o que tem menor teor de gordura (tabela 1).

Composição do leite em várias espécies (%). Fonte: JACOBISON, 1984. 3.4 Manutenção da lactação (galactopoiese) A capacidade da glândula mamária de secretar um grande volume de leite começa em/ou imediatamente antes do parto, para aumentar no período pós-parto durante um tempo variável e, posteriormente, diminuir de forma gradual. Em geral, existe um paralelismo entre a atividade secretora da glândula e a procura de leite por parte do lactente. Isto deve-se ao fato de sucção pelo lactente, ou a extração por ordenha, que constituem o fator fundamental para a manutenção da lactação. A sucção estimula a lactação de duas formas: a) reduzindo os efeitos inibitórios da pressão intramamária produzida pela acumulação de leite, e b) estimulando intensamente a secreção de hormonas necessárias para manter a síntese e secreção de leite nos alvéolos. As hormonas que desempenham um papel fundamental na manutenção da lactação são: I) a prolactina, que é responsável pela estimulação da síntese e secreção de leite nas células epiteliais nos alvéolos, e 2) a oxitocina, que provoca a contração das células musculares que circundam externamente os alvéolos e os ductos (células mioepiteliais). A libertação de ambos os hormônios ocorre como resultado de um reflexo neuroendócrino originado pela estimulação do mamilo. 3.4.1 Secreção reflexa de prolactina A secreção de prolactina é regulada por dois fatores hipotalâmicos: a dopamina, que inibe a secreção de prolactina e um fator cuja identidade não está bem definida, conhecido como fator liberador de prolactina (PRF)que estimula a liberação deste hormônio. O estímulo sensorial originado como sequência da estimulação do mamilo, pela sucção do lactente, é transportado através da medula espinhal para o hipotálamo, onde atua na inibição da dopamina ou estimulando a secreção do PRF para desencadear a secreção de prolactina da adenohipófise para a circulação sanguínea (figura 6). Figura 6. Reflexos neuroendócrinos secretores de prolactina e oxitocina. Fonte: HAFEZ, 2000. A prolactina estimula a secreção dos componentes do leite para a luz dos alvéolos, afim de repor o volume de leite extraído durante a última ordenha ou sucção. Ao mesmo tempo, a prolactina induz a síntese das proteínas, incluindo a alfa-lactalbumina para estimular novamente a síntese da lactosa, bem como as enzimas necessárias para a produção dos triglicerídeos. Desta forma, a secreção de prolactina originada pelo lactente durante o aleitamento proporciona um mecanismo simples para combinar o volume de produção de leite com as necessidades do lactente. A quantidade de prolactina liberada durante cada período de sucção depende do número de crias, da duração do estímulo e dos intervalos de tempo decorridos entre os períodos de sucção (ou ordenha). No caso das vacas leiteiras, as ordenhas são geralmente realizadas de doze em doze horas, intervalo de tempo suficiente para manter a lactogênese. Os valores plasmáticos de prolactina aumentam imediatamente após o início da ordenha, mas os valores mais elevados são obtidos cerca de meia hora após o início do estímulo (ordenha ou sucção). A secreção de prolactina e a produção de leite são influenciadas de alguma forma pelo fotoperíodo, uma vez que, em alguns animais se comprovou como o aumento do número de horas de exposição à luz dá origem a um aumento da concentração de prolactina circulante, bem como uma maior produção de leite (entre 6 e 10%) (trabalho e projeto elaborado pelos estudantes do curso técnico em agropecuária e da graduação em Medicina Veterinária do IFPB Campus Sousa sob a coordenação e orientação da profa. Me. Esp. Marianne C. Velaqua). 3.4.2 Reflexo da ejeção do leite A sucção do mamilo pelo lactente estimula os receptores sensoriais presentes nesta estrutura, originando a geração de impulsos nervosos que são transmitidos pelas vias nervosas ascendentes da medula espinhal para os corpos celulares produtores de oxitocina no hipotálamo. O estímulo desencadeia a síntese e liberação de um bolo de oxitocina através das terminações nervosas dos núcleos hipotalâmicos para a neurohipófise, da qual é transmitida, através do sangue, para a glândula mamária, provocando a contração das células mioepiteliais que rodeiam os alvéolos (figura 6). Além da estimulação direta do mamilo provocada pela sucção, qualquer estímulo relacionado à ordenha é capaz de gerar o reflexo da ejeção, por exemplo: os estímulos sensoriais auditivos (ruído dos cubos na hora da ordenha), visuais (ambiente da sala de ordenha), táteis (lavagem manual dos mamilos antes da ordenha) e os estímulos olfatórios que se produzem em torno do animal. O desencadeamento do reflexo de ejeção pelos estímulos sensoriais, que não estão diretamente relacionados com a sucção ou ordenha, indica a possível participação de centros superiores do sistema nervoso central para controlar a secreção de oxitocina. Esta teoria é baseada em que os estímulos relacionados com situações de estresse em animais de estimação (medo, ansiedade, frio, etc.) inibem a ejeção do leite. A contração das células mioepiteliais gera um aumento da pressão intra-alveolar mamária, provocando o deslocamento do leite para os ductos maiores da glândula. Este efeito é popularmente conhecido como diminuição do leite e constitui um mecanismo fisiológico muito eficaz para controlar a expulsão do leite para o mamilo, assegurando que a ejeção do leite se realize unicamente quando o lactente o demanda. O efeito estimulante da oxitocina é de grande importância já que a maior parte do leite se encontra nos alvéolos e nos ductos, com o qual, a ausência deste hormônio provocaria um lento movimento do leite para a cisterna do úbere e, portanto, uma menor quantidade de leite. Assim, quando os alvéolos e ductos menores são contraídos, ocorre o relaxamento dos ductos principais, bem como da cisterna (ruminantes) e do mamilo, o que dá origem a um aumento destas estruturas para alojar o volume de leite expelido. Como resultado da volumosa ejeção do leite dos alvéolos e ductos menores, ocorre um aumento da pressão intramamária de modo que o lactente terá que vencer a resistência do esfíncter do mamilo para poder extrair o leite. A produção de leite pela glândula mamária diminui gradualmente à medida que os intervalos de tempo entre os dois períodos de amamentação do lactente diminuem e os estímulos necessários para manter as concentrações de prolactina e oxitocina na circulação sanguínea. A diminuição ou cessação da secreção de leite, geralmente coincide com a mudança na alimentação das crias (desmame) para passar à dieta característica da espécie. 3.5 Colostro O colostro é o primeiro leite que se forma na glândula mamária coincidindo com o parto. A ingestão de colostro por recém-nascidos é de grande importância para a sua sobrevivência, não só pelo seu elevado valor nutritivo, mas também pelo seu teor em imunoglobulinas (IgA) que lhe confere a imunização passiva necessária para o proteger contra patologias. Em algumas espécies (homem, coelho e cobaia) grande parte dos anticorpos passam para a circulação do feto através da placenta durante a gestação. Nos animais domésticos (vaca, égua, ovelha, cabra, porco) as características da placenta (número de camadas entre a circulação materna e fetal) não permitem a passagem destas proteínas. Como resultado, a imunização das crias nestas espécies animais vai depender da transferência das imunoglobulinas através do colostro. O epitélio intestinal dos recém-nascidos permite a passagem destas imunoglobulinas durante as primeiras 24 a 48 horas de vida. Passado este tempo, o epitélio torna-se impermeável à passagem dos anticorpos, fato que põe em evidência a importância que tem para os animais recém-nascidos e desprovidos de defesas a ingestão do colostro durante os primeiros dias. A composição do colostro caracteriza-se (em relação ao leite normal) por um teor mais elevado de proteínas, vitaminas, minerais e uma menor concentração de lactose. A composição do colostro muda gradualmente durante os primeiros três dias após o parto para se transformar em leite normal. 4. RESUMO E PRIMEIRAS CONCLUSÕES O parto, ou processo fisiológico pelo qual se expulsa o feto, é o resultado da maturação sequencial de um sistema de comunicação hormonal. A sequência inicia-se no sistema nervoso central do feto de onde os sinais são transmitidos e amplificados, através da hipófise, para as glândulas adrenais fetais, as quais respondem ao estímulo mediante a secreção de cortisol. O aumento da concentração de cortisol por parte do feto indica que este conseguiu o desenvolvimento necessário para enfrentar a vida extrauterina e, portanto, é hora de interromper a gestação. O cortisol atua sobre a placenta para aumentar a secreção de estrogênios que, por sua vez, estimulam a síntese e a liberação de prostaglandinas. O resultado é a diminuição da progesterona, que é a hormona encarregada de manter a gestação ao inibir as contrações espontâneas do útero, impedindo assim a expulsão prematura do feto. O útero, sob os efeitos da prostaglandina, começa a contrair-se ao mesmo tempo que o colo uterino amolece e dilata progressivamente (fase preparatória do parto). A passagem do feto ao canal do parto origina a secreção reflexa de oxitocina (fase de expulsão), causando contrações de maior frequência e intensidade que culminam com a expulsão do feto. Finalmente, as contrações uterinas continuam durante algum tempo até que finalmente é expulsa a placenta (fase de expulsão da placenta). O desenvolvimento da glândula mamária durante a gestação e a subsequente capacidade desta estrutura para secretar leite, coincidindo com o parto, oferece aos animais pertencentes à classe biológica dos mamíferos a vantagem de alimentar as suas crias para assegurar a sua sobrevivência durante as primeiras fases do seu desenvolvimento e, portanto, a continuidade da espécie. A lactação constitui um dos processos fisiológicos mais complexos em consequência do grande número de hormonas que, segregadas de forma coordenada, controlam as diferentes fases pelo que atravessa este processo: I) mamogênese ou desenvolvimento dos dutos e estruturas lóbulo-alveolares durante a gestação; 2) lactogênese ou síntese láctea por células epiteliais e sua secreção para a luz alveolar coincidindo com o parto, e 3) galactopoiese ou manutenção da síntese e secreção do leite como consequência da sua extração da glândula mamária seja pela sucção da cria ou pela ordenha. -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.

The main contribution of this article is to apply Herbert Marcuse’s work in contemporary neoliberal society. Specifically, this article will focus on Marcuse’s critique of advanced industrial society and the role that technology plays in the quantification of the self. In this article, I will argue that in recent years, the development of technology has created the possibility to measure, calculate and quantify even the most trivial aspects of our lives, reducing people to numbers. The quantification of people (...) is done with the specific purpose of enhancing efficacy and productivity. I will unpack this notion by first looking to Marcuse’s critique of an advanced industrial society which he argues has the unique purpose of quantifying people to achieve a universal norm of calculated efficiency. Specifically, I will refer to Marcuse’s critique of industrial rationality as the prevailing rationality in advanced industrial societies which encourages the quantification of people. Secondly, I argue that Marcuse’s critique has evolved in the work of contemporary thinkers such as political economist Wendy Brown and cultural theorist Byung-Chul Han. I argue that Brown expands on Marcuse’s theories and contextualises those theories in contemporary neoliberalism. Specifically, I will focus on the concept of governmentality as a political rationality in neoliberal societies and how it advances a one-dimensional political passivity in neoliberal subjects. Finally, I refer to Han, whose theories explore the influence of new forms of technology in a neoliberal society and the development of the neoliberal subject as a “quantified self”. (shrink)

Over the last two decades, there was an upsurge of research and innovation in biotechnology and related fields, leading to exciting new discoveries in areas such as the engineering of biological processes, gene editing, stem cell research, CRISPR-Cas9 technology, Synthetic Biology, recombinant DNA, LMOs and GMOs, to mention only a few. At the same time, these advances generated concerns about biosafety, biosecurity and adverse impacts on biodiversity and the environment, leading to the establishment of Research Ethics Committees (RECs) at (...) Higher Education and Research Institutions dedicated to reviewing research with implications for biosafety and the environment. -/- These Biosafety and Environment Research Ethics Committees, referred to as EBRECs, are in the early stages of their establishment and formalisation, and there is much uncertainty about their composition, scope, procedures of decision-making and the principles that should guide their deliberations and assessments. In many respects, EBRECs are venturing into uncharted territory, facing a very wide range of complex research fields, far-reaching research practices and deep concerns new to Review Boards, raising the question to what extent EBRECs can fall back on the fairly well-established principles and procedures of RECs focusing on Human, Health or Animal research, and to what extent they need new or adapted principles and procedures. -/- Against this background, I set out to answer the following three main research questions in this thesis: 1. What is the current state of ethical principles for ethics reviews in the field of environmental and biosafety research ethics? Which principles are currently used in this context, and how? 2. What are the shortcomings of the current principles used by EBRECs and how can they be overcome? 3. What ethical principles must be adopted by environmental and biosafety research ethics committees and guide them in their decision-making? -/- In order to prepare the ground and set the scene for my discussion of these questions, I also formulated four supporting research questions: i. What is environmental research ethics in action? ii. What is biosafety research ethics in action? iii. How are environmental and biosafety ethics related to one another? iv. How should the guidelines and ethical principles related to these two overlapping fields be implemented in the ethics review process? Following my introduction and problem statement in Chapter 1, I devoted Chapters 2 and 3 to an overview of my supporting questions to set the scene for Environmental and Biosafety Research Ethics. In Chapter 4, I turned to my main research question with a discussion of national and international declarations, frameworks and legislation and an investigation of principles in the different research areas to get a picture of applicable principles that can guide EBRECs. -/- The main finding of my thesis is that due to the complexity of EBR, different categories of principles could be the solution for EBRECs. I elaborate on this in Chapter 5, my concluding chapter, in which I also propose a list of core principles that can serve as an accessible and easy-to-use guide for EBRECs in their decision-making. In this proposal, I cluster different kinds of principles in terms of four categories: 1. Principles as a Moral Concept 2. Principles as a Social Concept 3. Principles as a Legal Concept 4. Principles as a Safety Concept . (shrink)

Colonialism’s legacy in South Africa includes persistent economic inequality which, since the country’s universities charge fees, bars many from higher education, perpetuating the marginalisation of those previously disadvantaged by the apartheid regime. In 2015-6, country-wide unrest raged across university campuses, as students protested the yearly cycle of tuition increases under the slogan #FeesMustFall, demanding “free, decolonised education”. Protests ended in December 2017 when the government announced a sliding-scale payment policy alleviating the economic burden for poorer students. This paper (...) sets the #FMF movement and its twin demands within the context of decoloniality, and argues that while free education has been achieved, imagining and implementing decolonised education for South Africa in an increasingly globalised world is a more challenging, elusive goal.

Technological determinism, as a position on the nature and effects of technology/technologies can be divided into optimistic and critical forms. The optimistic variety, of which contemporary cyber-utopianism is an instance, holds that the development of technology shapes or at least facilitates ameliorative alterations in society. The critical variety, on the other hand, tends to problematise or condemn the positive narrative of technological impact on human existence. Whilst the optimistic form still retains some academic credibility, especially concerning digital technologies, (...) the critical variety tends to be viewed as reductionist, essentialist and pessimistic. Furthermore, the fact that many of its leading proponents base their critiques on the analysis of industrial technology, reinforces the impression that critical technological determinism is outdated. I argue that focussing on the specific forms of technology analysed by classic technological determinists is to miss the key point of their arguments. Critical determinism warns that with the increasing integration of technology into everyday life, we run the risk of idealising technological organisation and making sociotechnical relations a model for all social relations. Drawing upon Rendueles’s (2017) analysis of the sociophobic tendencies of the online public sphere, I argue for the continuing relevance of so-called ‘Classic’ technological determinism. The danger posed by the ubiquity of the internet on this account is not that it possesses some innate quality that imposes a particular social pattern on humanity, but that the way in which we interact in cyberspace becomes the norm for social relations outside the cybersphere.

In the wake of the advent of genome editing technology CRISPR-Cas9 (clustered regularly interspaced palindromic repeat (CRISPR)-associated protein 9), there has been a global debate around the implications of manipulating the human genome. While CRISPR-based germline gene editing is new, the debate about the ethics of gene editing is not – for several decades now, scholars have debated the ethics of making heritable changes to the human genome. The arguments that have been raised both for and against the use (...) of genetic technologies in human reproduction reiterate much of the arguments made in the pre-CRISPR debate. As such, it is instructive for South Africa to reflect on these arguments now, in considering our position on the regulation of the use of this novel biotechnology. There are two dominant schools of thought in this area, bioliberalism and bioconservatism. Bioconservatives raise concerns about the risks of genetic manipulation, and argue that it ought to be limited or prohibited to avert these risks to human health and human nature. Bioliberal scholars are more open to the prospect of genetic manipulation, because of its potential utility. In this article, I conclude that in liberal democracies such as our own, bioliberal arguments ought to be seriously considered when formulating policy on human genome editing because of the extent to which they resonate with our Constitutional values and human rights. I further suggest that there is a need for an enquiry into the relevance of African perspectives on the ethical questions that arise concerning germline genome editing. (shrink)

Abstract A COMPARISON OF THE VIEWS OF AUGUSTINE SHUTTE AND THADDEUS METZ ON AFRICAN PHILOSOPHY AND UBUNTU ETHICS In the theoretical study of Ethics much emphasis has traditionally been placed on established ethical theories, via approaches typified e.g. as deontological, divine command, utilitarian, virtue ethics and natural ethics. At UWC all these approaches, very much entrenched in the Western academic canon, have been taught, together with ethical views carried by the world religions. Over the last few years, however, an (...) interest in the study of African ideas (philosophy, theology, worldview studies, especially around the elusive but fascinating concept of Ubuntu) has grown. This study is an attempt to make a contribution towards a more serious exchange with African ethical ideas and their application in a global context. In this mini-thesis I compare the views of two academics, Augustine Shutte and Thaddeus Metz, who have actively and deliberately worked in the field of African philosophy and ethics. Through this comparative study of two rather different readings of Ubuntu philosophy, I wish to contribute to the growing interest in ethical views and discourse emanating from African ways of looking at the world and at humanity. The well-known, recently deceased, Augustine Shutte, a Catholic scholar of repute, taught Philosophy at the University of Cape Town, and published books such as Philosophy for Africa, The Mystery of Humanity; Ubuntu, An ethic for a New South Africa and The Quest for Humanity in Science and Religion, The South African Experience. The other scholar, the American born philosopher Thaddeus Metz, started teaching Philosophy at the University of Johannesburg and shifted his intellectual attention to African ideas and ethics. Coming from a rational Kantian approach, mixed with utilitarian ethical concerns, Metz discovered the difficulty of adding another “African mix” to main stream academia, based on the comprehensive scope of the very inclusive look at what it means to be human in the quite unique African worldview. He has published widely and in depth on many aspects of this “clash of cultures” while also holding on to enlightenment ideals and an ongoing conversation with science, especially also social science. These two authors thus share many concerns and interests, but also represent two different angles and approaches into African philosophy and ethics. The question for this limited study is formulated in the short introduction: How do Shutte and Metz connect the ethical implications of a widely shared “African worldview” with the core idea of Ubuntu, and which ethical implications do they draw from their reading of Ubuntu – for Africa and the world? These questions are addressed via five chapters: In the first an introduction to the research focus and question and the second of these the field of African Philosophy and Ethics is briefly covered via appropriate literature, thus providing a framework for comparing Shutte and Metz. The third chapter deals with Shutte’s search for an Ubuntu approach to South Africa’s problems within the African and global context - via his emphasis on an inclusive anthropology of caring and justice in which the pitfalls of individualism, materialism and consumerism can be avoided while promoting a sustainable work ethos and attunement with “science”. The fourth chapter focuses on Metz’ critical deontological approach, and his attempt to take the comprehensive African worldview seriously in conversation with utility, reason and science. In the fifth chapter the comparison of these two overlapping, but still quite different with an approach that can lead to a concrete ethical conclusion and application for South Africa, Africa and the world.

This article offers a prolegomenon for an African feminist philosophy. The prompt for this as an interrogation of Oluwole’s claim that an African feminist philosophy cannot develop until identifiable African worldviews that guide the relationship between men and women have been established. She argues that until there is general agreement about the nature of African philosophy itself, African feminist philosophy will remain impoverished. I critique this claim, unpacking Oluwole’s argument, and examine the contested nature of (...) both African and Western philosophy. Drawing from the work of Mignolo and decolonial thinking, I then argue for the possibility of “epistemic disobedience” concerning the emergence of an African feminist philosophy. Engaging with precolonial African examples which disrupt modern normative gender assumptions and looking at the project of decoloniality, I issue a call for an African feminist philosophy unfettered by the falsely universal claims of modernity/coloniality. My call is for an African feminist philosophy from African loci of enunciation, rooted in the epistemes and experiences of African women. (shrink)

All retailers are obliged to compete in an environment which is characterised by increasing competition, uncertain economic conditions and the increasingly sophisticated desires of consumers. In response, retailers have been prompted to improve not only the ranges of products which they offer, but the quality of their service as well. Some food retailers, however, have gained a reputation for the poor quality of their service. By contrast, those food retailers which consistently provide their customers with service which is perceived to (...) be of high quality are usually rewarded with high levels of both satisfaction and loyalty among their customers, which tends to minimise the likelihood of customers defecting to competitors and ultimately results in the retailers concerned maintaining their profitability in a sustainable manner. On the assumption that the youth represents a significant market for any retailer, it is a central tenet of this paper that retailers which are able to attract and muster support among the youth would inevitably increase both their viability and their sustainability. Accordingly, the study upon which this paper is based sought to gauge the perceptions of the youth of the importance of receiving high quality service from the large food retailers which they patronised most. A quantitative research approach was adopted to gather the data from a final research sample of 176 first year students who were enrolled to study towards the National Diploma in Retail Business Management at the Cape Peninsula University of Technology. Students who were studying towards this particular qualification were purposively selected because it was assumed that they would be familiar with retail concepts and be acutely aware of concerns pertaining to service quality. A self-administered questionnaire was considered to represent the optimal means of gathering relevant and appropriate data. The findings suggest that although large food retailers were generally perceived as successfully providing high quality service in some respects, in others they were generally less successful. It was evident that the respondents perceived, to a very significant degree, that the physical attributes of large retail food stores were the most important determinants of service quality. Attributes which pertained to convenience received particularly high ratings from the respondents, as did the quality of the products which were offered by retailers. Those determinants of service quality which pertained to interactions with the sales staffs of the retailers received the lowest ratings. The fact that the respondents rated the quality of the products which were offered as being of greater concern than their prices suggested that they would be inclined to remain loyal to large food retailers which met their perceived requirements for overall quality, which would include that of the service which they received from the retailers concerned, even if their prices were higher than those of their competitors.

There are calls from various sectors, including the popular press, industry, and academia, to incorporate artificial intelligence (AI)-based technologies in general, and large language models (LLMs) (such as ChatGPT and Gemini) in particular, into various spheres of the South African higher education sector. Nonetheless, the implementation of such technologies is not without ethical risks, notably those related to bias, unfairness, privacy violations, misinformation, lack of transparency, and threats to autonomy. This paper gives an overview of the more pertinent (...) ethical concerns that may result from the deployment of various current AI technologies in the South African higher education context. It provides a broad overview of the relevant AI ethics literature and distills a few general AI-ethics principles that can serve as guidelines for the ethical development, adoption, and use of AI systems. Suggestions are made as to how these might be applied to mitigate the ethical concerns in the South African higher education context. Overall, it is argued that AI technologies should only be adopted if they offer demonstrable benefits to stakeholders affected by them and that care should be taken to ensure that any potential harms are adequately addressed.

"The high unemployment rate that has become characteristic of the South African economy has generated some spinoffs that bode undesirable consequences, not only for economic development but also for sane social-cultural coexistence of the people. Recourse to entrepreneurship rather than clinging on to an endless hope for formal employment has been touted as a possible antidote for confronting the situation. However, a prerequisite to self-employment is entrepreneurial intention. This study therefore explores factors that may influence student entrepreneurial intention. (...) The study is based on quantitative data collected in a cross-sectional manner, from students at a South African university. Empirical results suggest that the respondent group strongly accede to the usefulness of entrepreneurship education for economic development which reveals that they are well-versed with the role and gains of entrepreneurship at a macro level. The study also found that perceived competency of the lecturing team demonstrates a moderate and positive correlation with student entrepreneurial intention. The implication of this is that institutions offering entrepreneurship programmes must saddle the responsibility to ensure that persons used to deliver the courses are not only highly competent but can kindle the entrepreneurial intention flame in students." .

This study examines the xenophobic attacks on Nigerians in South Africa, its ethical implications and responses of the Nigerian government. The study was guided by two objectives while it adopted the normative theory by Plato and Aristotle. The study looked at conceptual clarification like the concept of xenophobia. The study adopted ex-post research design while data was sourced through secondary source such as textbooks, journal articles, newspapers, magazines and internet while the data generated was analyzed through content analysis. The (...) findings of the study showed that there are Nigerians that are employees of labor in South Africa as well as Nigerians that are lecturers in South Africa universities that have contributed to their educational sector and there are also Nigerian students in their schools who pay fees as foreign students and these have contributed positively to South Africa economy and thus the reasons for these xenophobic attacks are not in accordance to the universalization of the norms of any society. The study also found out that the Nigerian government has responded in several ways which include, summoning of the South Africa ambassador to express her displeasure over the attacks on Nigerians, in the same vain Nigerians have used social media to call on the Nigerian government to boycott South African companies such as MTN, DSTV and Shoprite and also the immediate evacuation or repatriation of Nigerians in South Africa. Based on the findings the study recommended among others that the Nigerian government should let the South African government to know that the actions that are carried out by South Africans that has led to deaths of Nigerians no matter the actions that must had led to that does not fall within the moral principles of any society and the government of Nigeria should establish a bilateral commission with South Africa that will be meeting regularly to ensure protection of the two countries’ national interests.

Literature frequently describes how ineffective implementation of instructional policy frameworks can make distance learning a lonely and unrewarding academic pursuit, characterized by high student drop-out rates, high failure rates and academic exclusion. In trying to mitigate this catastrophe, academic departments in distance learning institutions utilize learning management systems (LMSs) to stimulate students’ learning experiences. In keeping with techno-progressivism, the researchers (and authors of this paper) turned to extant documentary policy and literature to review – qualitatively – how the University of (...) South Africa’s (Unisa’s) Open Distance Learning Policy (ODLP) promotes academic inclusion and learning agency as cornerstones of student success and social justice, especially in an unequal society like South Africa. The findings revealed the following: 1) Unisa’s ODLP position has the impetus to influence the deployment of the LMS to promote academic inclusion; 2) Practical means of promoting inclusion were mirrored in the provision of manual or electronic learning material, computer laboratories and free internet connectivity in regional centres across all nine provinces of South Africa, as well as in the provision of laptops for National Student Financial Aid Scheme (NSFAS)-funded students, 30 gigabytes of free monthly mobile data to all students, and assistive technologies for students with disabilities; 3) Practical utilization of an LMS to foster self-regulated learning occurred through problem-based individual activities supplemented by asynchronous demonstrative learning material (e.g. audio, video), while collaborative learning agency was enabled through e-tutoring, which afforded students the opportunity to interact with e-tutors and their peers about the learning content; 4) Drawbacks in the use of the LMS stemmed from the insufficiency of assistive learning technologies that are required for students with disabilities to participate fully in online learning, and a corpus of students’ irregular attendance at and participation in e-tutoring discussions and their projection of a negative attitude towards the e-tutors. -/- .

Throughout its brief history the philosophy of technology has been largely concerned with the debate over the nature of technology. Typically, technology has been viewed as being essentially another term for applied science, the practical application of scientific theory to the material world. In recent years philosophers and cultural critics have characterised technology in a far more problematic fashion, as an authoritarian power with the ability to bring about far-reaching cultural, political and ecological effects. Proponents of (...) the former view are often termed instrumentalists and those of the latter technological determinists. The debate between them revolves around the question of the fact/value distinction, namely whether technology can be deemed to be value-neutral. I argue that employing a phenomenological approach to technology grants us a fresh perspective on the instrumentalism-determinism debate. It enables us to recast the instrumentalist/determinist debate as a debate between technological idealism and materialism, and to ground the instrumentalist and determinist positions in different experiential relations to technology. It also gives us a better grasp of the function of the different critiques of technology, with idealists concerned primarily with the misapplication of technology as a form of knowledge, and materialists with the existential implications of concrete technological relations.

How can we ameliorate the current immigration policies toward Mexican people immigrating to the United States? This study re-examines how the development of scenarios assisted South Africa to dismantle apartheid without engaging in a bloody civil war. Following the scenario approach, we articulate positions taken by different interest groups involved in the debate concerning immigration from Mexico. Next, we formulate a set of scenarios which are evaluated as to how well each contributes to the well-being of the populace both (...) of Mexico and of the United States. The South African scenario model has proven to be an effective tool in times of political disagreement. It fosters a common language among competing groups, non-hierarchal communication among groups, and acknowledgement of the concerns of each group involved. (shrink)

This essay will attempt to inspect and discuss what ‘efforts’ have been made to recover from the apartheid regime, to explore the status quaestionis of peacebuilding and conflict transformation theories that have been formulated and consulted to advance and assess these efforts and to consider the reasons for the impact—or lack thereof—that these efforts have had on South Africa's recovery from apartheid era policies and transgressions. The central question towards which these points of focus are directed, is: are (...) class='Hi'>South Africa’s various recovery and reconciliation initiatives to be considered more of a success than a failure or vice versa?

Explanations of former South African President Thabo Mbeki’s public and private views on the aetiology of the HIV/AIDS epidemic in the country remain partial at best without the recognition that the latter presuppose and imply a postmodernist/postcolonialist philosophy of science that erases the line separating the political from the scientific. Evidence from Mbeki’s public speeches, interviews, and private and anonymous writings suggests that it was postmodernist/postcolonialist theory that inspired him to doubt the “Western” scientific consensus on HIV/AIDS and (...) to implement a public health policy that dragged its feet on full roll-out of antiretroviral therapy, causing thousands of avoidable deaths. A weak reductio ad absurdum allows us to conclude from this premise that postmodernist/postcolonial critique of “Western” science ought to be shunned. A comparative argument from consequences further suggests that in a situation where a misguided health policy has lead to a humanitarian catastrophe, and where postmodernist/postcolonialist critique of science can and has been used to justify this policy, an alternative theory ought to be preferred on which such justification would not be possible. The paper closes with a call for a non-relativist alternative to postmodernist/postcolonialist philosophy of science, and evaluates the potential of recent developments in ‘Studies of Expertise” to yield such.

Insofar as artificial intelligence is to be used to guide automated systems in their interactions with humans, the dominant view is probably that it would be appropriate to programme them to maximize (expected) utility. According to utilitarianism, which is a characteristically western conception of moral reason, machines should be programmed to do whatever they could in a given circumstance to produce in the long run the highest net balance of what is good for human beings minus what is bad for (...) them. In this essay, I appeal to values that are characteristically African––but that will resonate with those from a variety of moral-philosophical traditions, particularly in the Global South––to cast doubt on a utilitarian approach. Drawing on norms salient in sub-Saharan ethics, I provide four reasons for thinking it would be immoral for automated systems governed by artificial intelligence to maximize utility. In catchphrases, I argue that utilitarianism cannot make adequate sense of the ways that human dignity, group rights, family first, and (surprisingly) self-sacrifice should determine the behaviour of smart machines.

Background: The use of digital technology in higher education is overwhelmingly positively assessed in most recent research literature. While some literature indicates certain challenges in this regard, in general, the emphasis is on an encouragement and promotion of digital technology in higher education. While we recognised the positive potential of the use of digital technology in higher education, we were cautious of an instrumentalist and disembodied understanding of (digital) technology and its potential impact on higher education (...) – as a sector of education and as a body of students. Aim: To re-conceptualise the way in which technology is understood for its use in the higher education sector, as is argued, would be of benefit for transformation in higher education. Setting: South African Higher Education sector. Methods: Phenomenology of embodiment. Results: An embodied understanding of technology through the embodied phenomenology of Merleau-Ponty and an explication of its potential for transformation in higher education via the working concept of the Embodied Screen leads to a full understanding of the student as embodied and socially-embedded individual. Conclusion: A more holistic and embodied understanding of digital technology serves to supplement transformation in higher education, especially if transformation is itself understood in concrete social and bodily terms as is the case in the South African context.

Can a man be a feminist? If so, what would it mean? I want to participate in a dialogue between women and men on how to accommodate women’s moral concerns. I propose that the fundamental values of justice embodied in the South African constitutional democracy require men to be feminist. These values provide the best safeguard of the important interests and values of both women and men. Men who accept these values can support the main concerns of feminism. (...) The implications of the argument in this article range from public issues to the most private aspects of marriage. (shrink)

In the sea trade, the traditional paper-based bill of lading has played an important role across the globe for centuries, but with the advent of advanced commercial modes of transportation and communication, the central position of this document is under threat. The importance of the bill of lading still prevails as does the need of the functions that this document served in the past, although in a changed format. In the recent past, the world has witnessed a lot of debate (...) about replacing this traditional paper-based document with an electronic equivalent that exhibits all of its functions and characteristics, both commercial and legal. More specifically, unlike many rival travel documents, such as the Sea Waybill, a bill of lading has two prominent features, that is to say, its negotiability and its acceptability as a document of title in certain legal jurisdictions that are required to be retained in an electronic bill of lading so as to also retain the prominence of this document in the future landscape. This thesis is, however, more concerned about the legal aspects of adopting the electronic bill of lading as a traditional paper-based legal document as well as an effective legal document in the present age. However, the scope of this debate remains primarily focused on the USA and UK jurisdictions. In the course of this thesis, it is observed that, in the past, the bill of lading has been subject to a variety of international regimes, such as The Hague Rules and The Hague-Visby Rules, and presently efforts are being made to arrive at a universal agreement under the umbrella of The Rotterdam Rules, but such an agreement is yet to arrive among the comity of nations. On the other hand, efforts made by the business community to introduce an electronic bill of lading are much louder and more evident. The private efforts, such as the SeaDocs System, CMI Rules, and the BOLERO Project, etc., were, however, received by the fellow business community with both applause as well as suspicion. At the same time, there are a number of concerns voiced by the international business community on the legislative adoptability in national and international jurisdictions and the courts’ approach in adjudicating cases involving electronic transactions and these are making the task of adoption of electronic bill of lading in the sea-based transactions a difficult task. Therefore, in the absence of any formal legal backing from national and international legislations, these attempts could not achieve the desired results. In this thesis, the present situation of the acceptability of electronic transactions in general, and of the electronic bill of lading specifically, has also been discussed with reference to certain national jurisdictions, such as Australia, India, South Korea and China, in order to present comparative perspectives on the preparedness of these nations. On the regional level, the efforts made by the European Union have also been discussed to promote electronic transactions within its jurisdiction. All the discussion, however, leads to the situation where the level of acceptability of electronic bill of lading in the near future is found to be dependent upon the official efforts from the national governments and putting these efforts towards arriving at an agreement on Rotterdam Rules as early as possible. The other area of importance revealed in this thesis is the need for change in juristic approach by the courts while interpreting and adjudicating upon cases involving electronic transactions. On the whole, this thesis has provided a cohesive and systematic review, synthesis and analysis of the history of the bill of lading, its importance as a document of title, and attempts to incorporate its important functions within the fast-paced electronic shipping commerce of today. In such a way it has provided a valuable contribution to the literature by providing a comprehensive resource for jurists, policy-makers and the business community alike, as they work towards adapting the bill of lading so that it might be successfully applied in electronic form.

Aribiah Attoe took issue with the materialist and the non-materialist African conceptions of death by arguing that the reality of death puts pressure on the human conception of life’s meaning. He admits the reality of an afterlife experience through a causal principle that sees events in the world as the product of interactions between predetermined past events. It is an afterlife where a decomposing body continues interacting with other things in the world, not an afterlife involving consciousness. While conscious (...) meaning-making ends in the death of the body in Attoe’s materialist view, thereby affirming the conclusion that human existence is meaningless and the universe is purposeless, the conviction about life’s meaninglessness is also reinforced by the possibility of a second death, that is, the death of the transcendent consciousness in the traditional African view. In this article, I will mount two objections to Attoe’s submission. First, I argue that Attoe’s refutation of life’s meaning may be faulted by a world view devoid of the ideas of the afterlife and immortality. Life’s meaninglessness for him should have been limited to the facts of human existence in the world, not the human inability to continue meaning after death. Second, Attoe’s conception of death as finality questions his principle of causality that suggests the reality of an endless afterlife. Attoe’s overarching submission on life’s meaninglessness gives the impression that theories of life’s meaning must be anchored on the thought of an afterlife and immortality. (shrink)

Some international researchers assume that there is a lack of ethical review of research in many countries of the Global South. However, numerous African countries have recently introduced local and national research ethics guidelines. This article unpacks how ethical reviews of research in education are negotiated in a higher education institution in Ethiopia. It employs a critical analytical lens to challenge some of the assumptions of Beaty’s (2010) Institutional Review Board (IRB) stakeholder model. The article begins with a (...) discussion of the limitations inherent in the IRB model. Critical analyses of institutional documents and non-confidential, off-the-shelf IRB minutes are also conducted. The analysis shows that researchers within the medical and health sciences disciplines have well established organisational engagement when it comes to handling issues related to research ethics. However, limited representation of the educational and social and behavioural science disciplines remains a challenge. Furthermore, ethical issues in conducting educational research are hardly addressed in the national guidelines for granting research ethics approval. This results in further marginalisation of the contributions of educational research to knowledge production. (shrink)

The paper presents a novel take on the character of South Africa’s governance structure. It argues that, insofar as it constitutionally recognises traditional authorities, figures who rule in accordance with idiosyncratic and localised customary laws, as well as instigate a cheek-by-jowl existence of an asymmetrical property law (where in the urban setting land is nominally bought or transferred for sale, but in traditional rural areas granted by the chief), manifest in the differentiated land laws brought about by the Communal (...) Land Rights Act of 2003, is more akin to, and necessitates a definitional alignment with, the federal system of government than a unitary one – or at least a weak “federalism with South African characteristics.”.

Focused on women, this article investigates the qualities and attributes that family-owned businesses desire in a potential successor. This paper is the outcome of quantitative data that was solicited and collected from 120 participants using a semi-structured questionnaire. The Statistical Package for Social Sciences (SPSS) software was utilised to analyse the quantitative data and was complemented with the elements that were drawn from the qualitative data (open-ended questions). The results suggest that the incumbents prefer the potential successor to have management (...) skills; leadership skills; the ability to relate well with other members of the family; show interest in becoming a successor, possess greater aptitude than other members of the family; understands the business vision, be trustworthy; be committed to the business; has management experience; must be related by blood or law and able to harmonise the interests of the family with those of the business. Overall, this narrative highlights the woman’s position in a male-dominated discourse, besides suggesting that an understanding of the attributes desired by the incumbent will positively impact on the succession process in South African townships. -/- .

Although Knowledge Management was introduced as a Key Performance Indicator (KPI) for all senior management in South Africa 15 years ago, its implementation has been slow and inconsistent. This paper aimed to identify the factors that contribute to or deter the implementation of Knowledge Management in the South African government. The issue was explored through a review of literature on Knowledge Management, as well as results of an interview and questionnaire completed by government officials doing Knowledge Management (...) practitioner work in the South African government. The quantitative data was analysed using DATAtab. The findings identified two key factors that deter the implementation of Knowledge Management in the South African government: most departments in the South African government do not value Knowledge Management, and public officials responsible for implementing Knowledge Management in their departments lack implementation skills. A lack of research on Knowledge Management in developmental governments exists. More research on this subject is necessary. The research will benefit Knowledge Management and Public Administration practitioners alike. (shrink)

To investigate cultural lifestyle preferences in different cultural contexts, a forced-choice questionnaire was constructed, based on Thurstone's Law of Comparative Judgement, an almost forgotten statistical method of 1927, which is a useful tool for assessing groups. This study's questionnaire items targeted job and living conditions in the spectrum from traditional to globalised lifestyles. Subjects were indigenous representatives at the UNO in Geneva, and students in Nigeria, Cameroon, South Africa and Germany. The preferences ascertained reflect attitudes on a scale ranging (...) from very traditional to very globalised lifestyles. Although being an uncommon assessment tool, Thurstone's Comparative Judgement indicates to yield highly valid outcomes, as the results of the African university students, though from three different countries, resembled each other, but were complementary to the results of the indigenous representatives, which, in turn, mirrored the Berlin controls' profiles, according to expectations. Findings are discussed in light of the Symbolic Self-Completion Theory. (shrink)

The paper applies insights from Axel Honneth's recent book, The Struggle for Recognition, to the South African situation. Honneth argues that most movements for justice are motivated by individuals' and groups' felt need for recognition. In the larger debate over the relative importance of recognition compared with distribution, a debate framed by Taylor and Fraser, Honneth is presented as the best of both worlds. His tripartite schema of recognition on the levels of love, rights and solidarity, explains how (...) concerns for equality and difference are two separate needs, even though both must be satisfied. Past and ongoing struggles in South Africa can be understood as struggles for recognition. The African Renaissance itself, to be successful, must address economic and recognition issues simultaneously. (shrink)

Most studies on entrepreneurship have highlighted the relative importance of a conducive environment for the development of entrepreneurship. This notwithstanding, entrepreneurship has been noted to thrive even under the most adverse conditions, such as during economic, social and political instabilities. Using resilience as the propensity to bounce back after adversity and xenophobia, crime, unhealthy competition, etc. as correlates of adversity or an unconducive business environment, this paper investigated the preponderance of Somali grocery shops in South African township despite (...) the perceived hostility of the business environment. Anchored on the qualitative research approach, a purposive sample of 13 participants provided the required data for analysis. Specifically, the data collection took the form of focus group interviews in which two groups of 6 and 7 informants were purposively selected to be part of the interviews. Prominent in the results was the fact that almost all the current Somali grocery shops in the study area have been victims of crime and theft. Furthermore, virtually all the Somali grocery shops that were victimized during the xenophobic outburst have since re-opened. The foregoing themes of resilience and adversity unmistakably indicate the propensity of Somali grocery shop owners’ ability to bounce back. As to what township entrepreneurs worry or fear most, clearly, the fear of the re-occurrence of the xenophobic attacks surpassed that of burglary, theft and death. As to what fuels Somali’s persistence and preponderance in townships, both push and pull factors were reported. Reporting on risk aversion, it was noted that most of the founders (here referred to as an entrepreneur) are not actively involved in running the shops. They simply recruit others to do the job on their behalf. Under this circumstance, the risk is limited to financial risk. This approach is quite different for other African immigrants in the same township. -/- . (shrink)

This paper explores the incongruence between white South Africans’ pre- and post-apartheid experiences of home and identity, of which a wave of emigration is arguably a result. Among the commonest reasons given for emigrating are crime and affirmative action; however, this paper uncovers a deeper motivation for emigration using Charles Taylor’s concept of the social imaginary and Martin Heidegger’s concept of dwelling. The skewed social imaginary maintained by apartheid created an unrealistic sense of dwelling for most white South (...) Africans. After 1994, the conditions supporting this imaginary disintegrated. Many white South Africans feel so strong a sense of unease they can no longer dwell in the country. Many try to escape through emigration, but carry unresolved questions of identity and belonging to their new “homes.”. (shrink)

Intimate partner violence (IPV) perpetrated by women against men is a prominent yet hidden phenomenon. Given that little is known about this problem, this study set out to analyse discourses from publicly available groups, pages and accounts on Facebook to gain further insight into the perpetration of violence by women against men within heterosexual intimate relationships. This study is shaped by three objectives. First, the various forms of IPV that females perpetrated against their male partners were investigated in accordance with (...) the South African Domestic Violence Amendment Act 14 of 2021. Secondly, the study analysed publicly available discourses in the form of posts, comments and replies that Facebook Users employed to narrate IPV against men. Third, the study investigated the role of social media in the area of female perpetrated IPV. The application of critical discourse analysis as a theoretical framework exposed the hidden power dynamics that worked silently and implicitly in the texts to conceal the injustice and oppression of violence perpetrated by women against men. Legitimation strategies such as positive self-representation and negative representation of the ‘other’, were used to make IPV perpetration appear natural and necessary. Discourses of humour, demon possession and witchcraft signaled a strong denial of female perpetrated IPV. These discourses were shaped by masculinity ideology, patriarchy and the social conditions of the country. These factors determined properties of discourse as Facebook Users drew on them to make sense of female perpetrated IPV. The role of social media as a platform for engagements on this issue was equally crucial as users were able to resist power dynamics and counter dominant hegemonic discourses that legitimise female perpetrated IPV. While research on the subject of female perpetrated IPV in South Africa is growing, there is a still a gap from a social media perspective that analyses discourses from a critical linguistic perspective to reveal the hidden power dynamics that contribute to the continuation of this phenomenon. This study attempted to address this gap and concluded that masculinity ideology, patriarchy and high levels of femicide in the country are central to the legitimation of female perpetrated IPV.

Social networking technologies have become a ubiquitous framework for social interaction, serving to organise much of the individual’s social life. Such technological structuring affects not merely the individual’s psyche (as a psychotechnics), it also affects broader aspects of society (as a socio-technics). While social networking technologies may serve to transform society in positive ways, such technologies also have the potential to significantly encroach upon and (re) construct individual and cultural meaning in ways that must be investigated. Erich Fromm, who psychoanalytically (...) describes humans as a product of their society and the economic systems within that society, may provide insight into the influence of social networking technologies in contemporary society. He sees the relationship between the individual and society as being in a constant state of dynamic change. Utilising Fromm’s psycho-societal insight, social networking technologies are shown to conflate and confuse the relation between Thanatos and Eros – the Thanatos of a lifeless and consumerist agenda-filled mechanisation, and the Eros associated with social engagement. Thanatos and Eros are tied together via social networking technologies. This results in, firstly, social networking technologies functioning predominantly to further capitalist agendas through the monetisation of these technologies – particularly in terms of linking commodity fetishism and the foundational social drive of the individual. Secondly, social networking technologies mechanise human action according to predictable behavioural paths through the use of these technologies, especially in terms of how socialisation is possible via these technologies (shaping how platonic and romantic relationships may take place in the contemporary world). Such a mechanisation of interpersonal engagement contrasts with Erich Fromm’s assertion that interpersonal relations (vis-à-vis love) are not “mere emotion”, but rather represent an interpersonal creative capacity and interplay. Fromm’s psycho-societal insights will show how contemporary individuals may take independent and responsible rational action to establish accountable and psychologically beneficial ways of engaging with others through social networking technologies.

This is the book of abstracts of the 19th Brazilian Logic Conferences. The Brazilian Logic Conferences (EBL) is one of the most traditional logic conferences in South America. Organized by the Brazilian Logic Society (SBL), its main goal is to promote the dissemination of research in logic in a broad sense. It has been occurring since 1979, congregating logicians of different fields — mostly philosophy, mathematics and computer science — and with different backgrounds — from undergraduate students to senior (...) researchers. The meeting is an important moment for the Brazilian and South American logical community to join together and discuss recent developments of the field. The areas of logic covered in the conference spread over foundations and philosophy of science, analytic philosophy, philosophy and history of logic, mathematics, computer science, informatics, linguistics and artificial intelligence. Previous editions of the EBL have been a great success, attracting researchers from all over Latin America and elsewhere. -/- The 19th edition of EBL takes place from May 6-10, 2019, in the beautiful city of João Pessoa, at the northeast coast of Brazil. It is conjointly organized by Federal University of Paraíba (UFPB), whose main campus is located in João Pessoa, Federal University of Campina Grande (UFCG), whose main campus is located in the nearby city of Campina Grande (the second-largest city in Paraíba state) and SBL. It is sponsored by UFPB, UFCG, the Brazilian Council for Scientific and Technological Development (CNPq) and the State Ministry of Education, Science and Technology of Paraíba.

The purpose of the study is to determine the relationship between the level of usage to technological devices and the academic performance of Grade II learners in selected Multigrade School in Hilongos South District, Hilongos, Leyte. The study used descriptive survey design since the researcher used checklist to determine the learner’s level of usage to technological devices and survey it used open-ended question to determine how technological devices help the learners in learning. More so, both qualitative and quantitative data (...) were being gathered for the further validation of the quantitative data of the study. The result shows that the level of usage of the learners is at Normal Level. The learners understudy is using technology devices at a tolerable level, that is, 3 – 4 hours in a day. The learners performed well in English with a Closely Approaching Mastery Level in their Quarterly Assessment. The level of usage of the learners to technological devices has a significant relationship with the English performance of the learners. The more exposed the students are to technological devices the more affected their performance in English are. Using to technological devices has a detrimental effect on English performance of the learners. Hence, the parent’s guidance to their children is a must. It can be concluded that usage to technological devices can significantly affect performance. As resulted, using to technological devices has a detrimental effect on English performance. The use of television, cellphones, tablets and computers at a regular basis affects the academic performance of the learners. The more they are using technological devices, the more their academics are negatively affected. Hence, parents or guardian of the learners should be watchful to their children so that they can guide and discipline them in using technological devices to evade bane result from these devices.

It has been the better part of a century since the appearance of Dialectic of Enlightenment, and the technologies of mass communication that Adorno and Horkheimer placed at the centre of their analysis of mass culture have altered beyond recognition, and with them the culture itself. And this in turn raises the question of the continuing relevance of the ‘culture industry’ concept. Does the contemporary culture industry still operate along the same lines that Adorno and Horkheimer charted or has it (...) evolved to a point at which their analysis no longer applies? This special issue gathers together a broad range of theoretical approaches that address the pressing need for the analysis of the contemporary culture industry in the Global South and beyond. Through the lenses of the history and theory of Critical Theory (and African critical theory traditions) and topics including digital culture, neoliberalism and its effects, and environmental praxis, the culture industry of Adorno and Horkheimer is revisited in the spirit of renewal and positive critique.

This study assessed quality assurance practices and students’ performance evaluation in universities of South-South Nigeria using an SEM approach. Three null hypotheses guided the study. Based on factorial research design, and using a stratified random sampling technique, a sample of 878 academic staff were drawn from a sampling frame of 15 universities in South-South Nigeria. Quality Assurance Practices Students’ Performance Evaluation Scale (QAPSPES) with split-half reliability estimates ranging from .86–.92, was used as the instruments (...) for data collection. Multiple regression and Confirmatory Factor Analyses (CFA) were used for the analysis of data, model building, and testing of the hypotheses at .05 alpha level. Findings showed a significant composite and relative influence (F=48.19, P<.05) of school management, staff, and students’ quality assurance practices on students’ performance evaluation. The results also indicated that there were positive and significant covariances between the four variables of this study, with the CFI, RMSEA, TLI, and SRMR values indicating a good model fit. It was recommended, based on the findings of this study that, each school should organize quality assurance orientation campaigns for new students and set up quality assurance committees at the school, faculty and departmental levels for optimal performance in schools.

In this chapter, a reprinted article from Southern African Public Law (2010), I argue that, even supposing substantive principles of distributive justice entail that animals warrant constitutional protection, there are other, potentially weightier forms of injustice that would probably be done by interpreting a Bill of Rights as implicitly applying to animals, namely, formal injustice and compensatory injustice. Formal injustice would result from such a reading of the Constitution in that the state would fail to speak with one voice (...) upon newly according legal rights to animals. Compensatory injustice would likely result from such a reading, at least in a South African context, in that the law would not only suppress facets of culture that many Africans deem important to their self-conception, but also require spending scarce resources on animals that could have gone toward saving African lives and livelihoods. If the state must choose between acting for the sake of the urgent interests of animals and those of humans, humans must take priority, even assuming that animals have a worth that morally forbids harming them in our private lives.

To illustrate the abounding confidence in which Plato’s Republic can help us understand crime, I shall explore three interrelated avenues. The first avenue will include societal themes such as leadership, the state-of-nation, national-cohesion, good governance, institutional memory, tradition and structural inadequacies. This will illustrate how flawed leadership and a flawed system inevitably expose a society to be plagued by crime.

In this article, I expound and assess two theories of meaning in life informed by the indigenous sub-Saharan African philosophical tradition. According to one principle, a life is more meaningful, the more it promotes community with other human persons. According to the other principle, a life is more meaningful, the more it promotes vitality in oneself and others. I argue that, at least upon some refinement, both of these African conceptions of meaning merit global consideration from philosophers, but (...) that the vitality approach is more promising than the community one for capturing a wider array of intuitions about what confers meaning on a life. I further argue, however, that there are objections that apply with comparable force to both theories; neither one does a good job of entailing that and explaining why certain types of reason and progress can make a life more meaningful. Although these objections are characteristic of a ‘modern’ western outlook, I maintain that they are difficult for contemporary African philosophers to ignore and consider some ways they might respond to the objections.
