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)

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.

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.

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)

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)

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.

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)

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)

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.

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)

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.”.

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)

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. -/- .

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)

In its ideal conception, the post-apartheid education landscape is regarded as a site of transformation that promotes democratic ideals such as citizenship, freedom, and critical thought. The role of the educator is pivotal in realising this transformation in the learners she teaches, but this realisation extends beyond merely teaching the curriculum to the educator herself, as the site where these democratic ideals are embodied and enacted. The teacher is thus centrally placed as a moral agent whose behaviour, in the classroom (...) space particularly, should, ideally, represent and communicate the values we aspire to cultivate in post-apartheid South African society generally. Thus, this notion of what teaching encompasses fits broadly into the conception of a “practice” in the sense developed by Alasdair MacIntyre, in that it is a transformative activity the enactment of which not only benefits the practitioner, but also extends to and benefits the broader community as well. Furthermore, practices are grounded in features of social or moral life we hold to be significant and, importantly, it is only through their active cultivation that they can be made tangible and further developed. MacIntyre’s theory of virtue is based on a three-fold interrelationship between practices, how they meaningfully narrate and shape an individual life, and how, in turn, this builds and sustains our moral and social traditions. Using these ideas to analyse post-apartheid South Africa, and the structural transformation paradox it is in, reveals the difficult and complex nature of a society that is in this transitional space. The claim is that attentiveness to practices in the educational space, and to the way they shape and inform moral and social traditions, is necessary to more fully understand and guide this societal transformation.

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)

In this paper I attempt to unpack the current public debate on racial transformation in South African sport, particularly with regard to the demographic make-up of its national cricket and rugby sides. I ask whether the alleged moral imperative to undertake such transformation is, in fact, a moral imperative at all. I discuss five possible such imperatives: the need to compensate non-white South Africans for the injustices in sport’s racist history, the imperative to return the make-up of (...) our national sides to what they would have been in the absence of that history, the requirement that national sides be representative of the country, the need to eliminate ongoing racial bias in selection, and the obligation to provide all South Africans, regardless of their race, the opportunity to compete as equals for places in the national side. I argue that the first three, drawn from talk of “rectifying the injustices of the past,” “achieving demographic proportionality between the sides and the country,” “representivity,” and “transformation” itself, are not compelling. The remaining two are of great moral import, but that the sorts of phrases just mentioned, and which are frequently used in the debate, have little to do with those genuine moral requirements.

Since independence, at least 28 African countries have legalized some form of gambling. Yet a range of informal gambling activities have also flourished, often provoking widespread public concern about the negative social and economic impact of unregulated gambling on poor communities. This article addresses an illegal South African numbers game called fahfee. Drawing on interviews with players, operators, and regulatory officials, this article explores two aspects of this game. First, it explores the lives of both players and (...) runners, as well as the clandestine world of the Chinese operators who control the game. Second, the article examines the subjective motivations and aspirations of players, and asks why they continue to play, despite the fact that their aggregate losses easily outstrip their aggregate gains. In contrast with those who reduce its appeal simply to the pursuit of wealth, I conclude that, for the (mostly) black, elderly, working class women who play fahfee several times a week, the associated trade-off—regular, small losses, versus the social enjoyment of playing and the prospect of occasional but realistic windfalls—takes on a whole new meaning, and preferences for relatively lumpy rather than steady consumption streams help explain the continued attraction of fahfee. This reinforces the need to understand players’ own accounts of gambling utility rather than simply to moralistically condemn gambling or to dismiss gamblers behaviour as irrational. (shrink)

This paper is based on the premise that public officials in developing countries lack the necessary skills to implement Knowledge Management (KM) successfully, so a framework is required to facilitate this process. South Africa is the case study. It is therefore necessary to develop a Knowledge Management Implementation Framework (KMIF). Consequently, one of the objectives of this paper is to validate this need and then outline a KMIF that can help government departments in developing countries implement KM and foster (...) a KM culture. A mixed methodology approach was used, combining qualitative and quantitative data collection. Based on the Taro Yamane formula, 139 people were selected from a target population of 221 officials involved in KM in the South African government. DATAtab, a web-based statistics application, was used to analyze the responses. A comprehensive review of several secondary literature sources was carried out. For the literature review, relevant peer-reviewed articles were downloaded from Google Scholar, ResearchGate, Scopus, and Phil Papers. The study posits that officials charged with KM implementation in the South African government lack the necessary implementation skillset, that a need for a KMIF exists, and subsequently outlines a three-stage KMIF to facilitate their efforts. This study recommends that the proposed three-stage KMIF be adopted since it will provide the government (i) a simplified and structured way of realizing KM; (ii) it will be an effective tool that officials can use to guide them on how to implement KM, and (iii) it will cultivate a KM culture within the government. Even though the study is original to the South African government, the findings, however, may be applied to other emerging governments in Africa and beyond. Despite its theoretical nature, the paper lacks empirical validation, leaving it open to further investigation. (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)

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.

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.

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)

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)

Since the transition to a constitutional order, in what respects have cultures in higher education institutions in South Africa become Africanised, and, going forward, how should they be? In this chapter I provide an overview of the major different forms that Africanisation of institutional culture could take, and I then indicate the respects in which South African universities have or have not taken them on board over the past 20 years. In addition, I provide the first (...) comprehensive critical discussion of the major reasons that have been given for Africanising. Specifically, I distinguish between five rationales for Africanising institutional culture, namely, those appealing to relativism, democracy, redress, civilisation and identity, bring out their different implications for the forms that Africanisation should take, and argue that some of these rationales are philosophically much more promising than others. I conclude that the rationales of redress, civilisation and identity together make a compelling case for a moderate form of Africanising the institutional culture of public universities, one that would be much more robust than what has appeared so far on the democratic landscape in South Africa.

WHO in 2019 established the Advisory Committee on Developing Global Standards for Governance and Oversight of Human Genome Editing, which has recently published a Draft Governance Framework on Human Genome Editing. Although the Draft Framework is a good point of departure, there are four areas of concern: first, it does not sufficiently address issues related to establishing safety and efficacy. Second, issues that are a source of tension between global standard setting and state sovereignty need to be addressed in a (...) more nuanced fashion. Third, it fails to meaningfully engage with the extent to which the conceptualisation of human dignity may justifiably vary between jurisdictions. Fourth, the meaning of harm to the interests of a future person requires clarity. Provided these four areas of concern can be addressed, the future of the global governance of human genome editing may hold promise. (shrink)

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.

"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." .

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)

Background: Although inclusive education is widely discussed, its implementation has not, arguably, been far-reaching. There remains a lack of specific, targeted approaches towards fully including learners with physical and mental impairments in the educational space. Objectives: This study investigated the extent of the inclusion of learners with autism spectrum disorder (ASD) in three schools in Johannesburg. Method: A qualitative interpretivist design was adopted. Teachers who work with learners with ASD were interviewed using open-ended questions. The sampled data were analysed using (...) thematic analysis, making use of both a priori codes and emergent codes that arose from the open-ended questions. Results: The findings reveal numerous pedagogic strategies such as differentiation, scaffolding, use of visual cues, group work and collaboration that can include learners with ASD in the classroom space. Conclusion: Teacher collaboration and teacher training are vital in ensuring that learners with ASD are fully included in the classroom space. (shrink)

The study examined the influence that the psychological contract has on the job satisfaction and dissatisfaction of employees in the South African workplace. It also studied in detail, the effect that psychological contract breach and fulfilment have on the satisfaction of employees with regard to their work, fellow-employee, supervisor, and the as a whole organisation. The data for this study therefore, was collected through perusal of existing scientific articles/papers, published/unpublished dissertations and theses, text books and other relevant informative (...) documents. This makes the study to be premised on theoretical and analytical methodology. This article therefore, reveals the destructive effects that psychological contract breach has on the operation of organisations in South Africa, which are also presented and discussed in detail. The article also reveals the costly effect that employees’ job dissatisfaction has on organisations in terms of unplanned employee turnover. For the enhancement of psychological contract fulfilment, this article proposes strategies for organisations to adopt and implement, with an aim of improving employees’ job satisfaction in the workplace and ultimately discouraging turover intentions among employees. This study therefore, plays a very important and significant role in terms of contributing to literature and better understanding of psychological contract in general, and the effects that psychological contract has on employees’ job satisfaction and dissatisfaction in particular.

Given the growing interest in entrepreneurship education and the quest to provide entrepreneurial skills to all including the youths, the study investigates high school learners’ interest and readiness to start a business in South Africa. A group of high school learners (n=403) from select high schools in Cape Town was purposively sampled using self-administrated questionnaires while personal interviews were held with all Business Studies teachers in the participating schools (n=9). The results of this study indicate that 52% of the (...) learners are interested in starting a business, while 73% of them were from moderate income schools. A chi square test was performed to determine if the race and income level of the school influenced learners’ responses, and we found no statistical significance (P > 0.01). An overwhelming majority of the learners (73%) was of the view that they could start a business with the help of the knowledge and skills gained in the entrepreneurship education received. Suggestions on how to increase high school learners’ entrepreneurial intent and readiness to start a business upon leaving high school include the implementation of frequent learner visits to businesses as well as inviting entrepreneurs to give talks to learners. The goal of any scientific social enquiry such as the one pursued in this study, is to produce knowledge that assists in distilling viewpoints that express accurate necessities for socioeconomic development. Therefore, the practical implications of the study reside in the reinforcement of the need for a curriculum that addresses entrepreneurship education in South African high schools. -/- . (shrink)

The concept of Sustainable Public Procurement (SPP) has attracted the interests of academics, practitioners, policymakers and the media recently. The interest can be attributed to the strategic role of purchasing and supply chain as a lever for sustainable development. Despite the enormous amount of funds spent on public procurements in South Africa annually, tender irregularities, corrupt practices, non-compliance and lack of knowledge, casts doubts on its role in fostering sustainable development. An in-depth literature review on SPP implementation was adopted (...) to analyse the manner in which sustainability could be realised through regulation, implementation and monitoring compliance of relevant environmental policy instruments. This approach is used to determine how due consideration of sustainable procurement has been used as a tool to enhance social, economic and environmental sustainability. This article notes that in many developed and developing countries, the dare need of technical and management competence, cultural assimilation, high costs of funding sustainable procurement projects and transparency on the part of managers among others are sighted as factors plaguing the growth of sustainable procurement practices in most institutions. Further, this paper puts forth the argument that implementation of sustainable procurement policies alone, will not necessarily help in the achievement of the developmental objectives, but due consideration should be given to capacity building and collaboration with relevant units of government, whilst also integrating social and economic policies, into the formulation of tender documents and selection of suppliers. This paper posits that to overcome these challenges faced by South Africa, it is important that all stakeholders including the government, researchers and other agencies should construct a synergy capable of addressing salient issues for progressive sustainable procurement policies and actions, through the incorporation of sustainable procurement practices into the mainstream of both the public and private organisations through relevant legislations, policies and regulatory frameworks.

An assessment of the extent of the use of electronic platforms by African academic staff in universities to disseminate research was done in this study. The study is informed by the growing importance of online repositories and preprint servers in the scientific communication of scholarly output, especially in an era where the use of metrics for research appraisals and funding decisions is commonly practised. The quantitative research method was adopted, based on the descriptive survey research design. The snowball (...) sampling technique was used for data collection. Data were collected from 1,977 respondents, distributed across 24 African countries, through the use of an electronic survey. There was a high rate of willingness among universities’ academic staff in Africa, to adopt various online platforms for research dissemination; ResearchGate is currently utilized the most for research dissemination, but Google Scholar is the platform respondents are more willing to adopt for research dissemination; the rate at which academic staff research output can be found online as a ratio of their total publication is 64.04% and in the ratio of 2.00:3.12; poor access to Internet facilities at home and workplaces are the major challenges academic staff face in the utilization of digital platforms for RD. It was recommended, amongst others that academic staff in universities should endeavour to explore and utilize at least ten of the online platforms mentioned in this study, to enable them disseminate their scholarly works to a wider audience and for increased visibility Keywords:.

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)

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)

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.

Using a triangulation of three methods, we devise a framework for the acquisition of the resources vital for the start-up of a business in South Africa. Against the backdrop of the fact that numerous challenges prohibit African immigrants from starting a business, let alone growing the business, we set out to investigate how those who succeed acquired the necessary resources. Within the quantitative paradigm, the survey questionnaire was used to collect and analyze the data. To complement the quantitative (...) approach, personal interviews and focus groups were utilised as the methods within the qualitative approach paradigm. The research revealed that an African immigrant entrepreneur is most likely to be a male between the ages of 19 and 41 who has been forced to immigrate by political circumstances. Once in South Africa, limited job opportunities forced these immigrants into starting up a business. In order of importance, financial, informational, human and physical, resources were identified as being critical for the start-up a business. With respect to the acquisition of resources, African immigrant entrepreneurs unwillingly made use of personal savings to finance their businesses during the start-up phase of the business. Financial resource played a double role in that it determined the main sources of physical resources used. From a human resource perspective, African immigrant entrepreneurs preferred employing South Africans during the start-up phase of the business, and the reverse was true during the growth phase. To a limited extent family labour was involved at both the start-up as well as the operation phases of the business; with formal education and prior experience playing an indirect role as far as the human resources mixed were concerned. In terms of information, African immigrant entrepreneurs made use of two primary sources of information namely; their ethnic networks and friends from somewhere else. -/- . (shrink)

Attacks on migrant and refugee entrepreneurs and their properties by South African rivals and ordinary citizens have become a common phenomenon throughout the country, including the city of Cape Town. Business robberies often result in deaths or serious injuries. The Somali Community Board has noted that over 400 Somali refugees, many of them informal traders, were murdered in South Africa between early 2002 and mid-2010. The police are frequently accused by migrants of fomenting or turning a blind (...) eye to xenophobic attacks on their businesses. Meanwhile, the government refuses to acknowledge the existence of xenophobia or the xenophobic rhetoric in many of these attacks, claiming instead that they are simply the actions of criminal elements. Photographs published in the media of the looting of migrant stores do not tend to feature hardened criminals, but ordinary citizens including children in school uniform. -/- Migrant businesses are portrayed by officials, citizens and the media as having a negative impact on the South African economy and undermining the livelihoods of South Africans. The prevalence of such perceptions helps to explain growing xenophobic sentiment against migrants and refugees. Contrary to these popular perceptions, an emerging literature on migrant entrepreneurship is beginning to demonstrate the positive economic contributions of migrants and refugees to the country. This report examines the nature of informal migrant and refugee entrepreneurship in Cape Town and whether or not the negative stereotypes have any validity. It also seeks to examine what economic contributions migrants and refugees make to the local economy. -/- The report is based on the research conducted by the Growing Informal Cities project, a partnership between SAMP/IMRC, the African Centre for Cities at the University of Cape Town, the Gauteng City-Region Observatory (GCRO) and Eduardo Mondlane University in Maputo. A questionnaire was administered to a sample of 518 migrant owners of microenterprises, which had to meet three basic criteria for inclusion: (a) owned by a non-South African; (b) in operation for at least two years; and (c) unregistered with the South African Revenue Services (SARS). Although migrant entrepreneurs are located in most areas of the city, certain areas have particular concentrations of migrant-owned businesses. "e questionnaires were administered in four such areas: Imizamo Yethu, Philippi, Bellville, and Cape Town CBD. Thirty in-depth interviews were also conducted with selected owners of informal micro-enterprises. Two focus group discussions were held in the Cape Town CBD and Philippi respectively. Fifteen key informant interviews were held with various stakeholders in Cape Town to understand the operation and constraints faced by migrants operating in the city’s informal economy. -/- The major findings of the personal profile of the migrant and refugee entrepreneurs were as follows: -/- • The entrepreneurs came from over 20 different countries of which Zimbabwe, Somalia, the Democratic Republic of the Congo (DRC), Nigeria, Malawi, Ethiopia and Cameroon were the most prominent. Just over a third were from other countries in the SADC. The prominence of Zimbabwean entrepreneurs in the Cape Town informal economy is not surprising, given the events in that country over the past decade and a half and resultant mass migration to South Africa. A total of 57% of the entrepreneurs were from other African countries, especially the DRC, Somalia, Nigeria and Ethiopia. "e majority of migrants from these countries (except Nigeria) came to South Africa as refugees. -/- • A third of the entrepreneurs had refugee permits. Of these, nearly 60% came from only three countries: the DRC, Ethiopia and Somalia. A further 31% held asylum-seeker permits. Of these, 32% were Zimbabwean while another 30% came from DRC, Ethiopia and Somalia. Nearly 12% had permanent residence permits while 8% were holders of work permits. Only 7% of the respondents indicated that they did not have official documentation to stay in South Africa. Thus, the majority of migrant entrepreneurs have forced migrants who are entitled to human rights protection under international and South African refugee law. • Very few of the entrepreneurs entered South Africa before 1994. Only 8% arrived in the immediate post-apartheid years. While another 20% came in the period 2000to 2004, the vast majority (70%) came during the last decade. As many as 44% arrived between 2005 and 2009 and a further 27% thereafter. Migration from Zimbabwe, in particular, escalated between 2005 and 2009 as the country plunged deeper into crisis. • Despite the perception that unemployment at home is a driver of migration to South Africa, only 14% of the entrepreneurs were unemployed immediately before leaving for South Africa. Another 19% were students. Twenty-six percent were working in the informal economy in their home countries. -/- .......INCOMPLETE..... (shrink)

Los cambios tecnológicos ya habían impactado desde hace más de dos décadas en el aula de las universidades. Sin embargo, el crecimiento de las herramientas virtuales como soporte del proceso de enseñanza aprendizaje se acentuó a raíz de la pandemia provocada por el COVID 2019. Este paper muestra una revisión de la literatura sobre el impacto de las nuevas tecnologías en la enseñanza de grado desde una doble mirada. Se analizan los aportes y experiencias anteriores, focalizadas en las pruebas acreditativas (...) basadas en tecnología (computer based assessment), el impacto de las plataformas en la enseñanza de grado y los recursos audiovisuales mayormente utilizados. Asimismo, se efectúa una mirada de los conocimientos sobre tecnología que requiere un docente, partiendo de la construcción de Lee Shulman en los 80 y las adaptaciones de Mishra y Koehler mediante el modelo TPACK. El artículo finaliza con la propuesta de un modelo adaptado a la realidad de las universidades públicas sudamericanas. (shrink)

[First paragraph]: On Wednesday, June 8, 2011, UK’s The Guardian reported that numerous US universities including Harvard and Vanderbilt were invested in companies that were buying large tracts of African farmland and kicking off the indigenous farmers in order for their employees (mostly non-Africans) to grow cash crops to sell to Europe.1 Harms associated with this land-grabbing include, in addition to the evictions themselves, corruption among African governments and among absentee African land owners, increased food prices, (...) and accelerated climate change.

Aim: Underscoring the xenophobic violence that has befallen African immigrants in South Africa in the recent past is the perception held in certain quarters that African immigrants take away entrepreneurial opportunities among others from the Natives. This paper sought to determine how African immigrant entrepreneurs identify business opportunities in South Africa in tandem with what South African entrepreneurs could learn from African immigrants. -/- Method: The paper was based on quantitative data from (...) 220 participants collected by way of a semi-structured questionnaire. As such, the study benefited from the qualitative insights associated with the use open-ended questions in the questionnaire. The data was analyzed using version 24 of the Statistical Package for Social Sciences (SPSS) software. -/- Results: suggest that African immigrants uncover entrepreneurial opportunities through: startup partners, previous employment, families, through ethnic networks, prior knowledge of the market need, prior knowledge of how to serve the market and prior knowledge of the challenges serving the market. Value/Contribution: this study is premised on the fact that no previous study has attempted to investigate how immigrants identify business opportunities, in tandem with what South African entrepreneurs could learn from African immigrants. -/- Implications: Considering the close parallel between African immigrants and the indigenous black South Africans, it is to be hoped that the study would be of interest to the latter in particular, policy makers and academics in general.

Drawing on the literature on the support of small businesses and case studies, this article advances the case for the support of African immigrant-owned businesses in South Africa which is currently neglected. In the past justification for the institution of support policies in favour of small businesses was predominantly based on the fact that they disproportionately encountered more obstacles than their larger counterparts. Shying away from the traditional “business focus” justification for the support of small business, this study (...) advances an “owner focus” justification - one that is based on the unique needs of the owner, rather than that of the business itself. Following similar logic, given that most immigrants start small businesses as a means of survival in their host countries, this study advances an even more compelling reason why immigrant-owned businesses should be supported. Acknowledging the role that a supported small business sector in general and immigrant-owned business, in particular, can play in the economy and taking steps to strengthen this sector would be in the right direction for the South Africa government.

Given the fact that numerous challenges prohibit African immigrants from availing financial capital for the purpose of starting a business in South Africa, this paper sets out to investigate whether those that succeeded experienced a significant increment in their financial capital three or more years after startup. This paper was designed within the quantitative and qualitative research paradigms. A triangulation of three methods was utilised to collect and analyze the data. From a quantitative perspective, the survey questionnaire was (...) utilised. To complement the quantitative approach, personal interviews and focus groups were utilised as the methods within the qualitative approach paradigm. The primary data collection instrument used was the survey questionnaire which was complemented by personal interviews and focus group debates. The results revealed that the majority (71.1%), of African immigrants, had an estimated start-up financial capital in the range of R 1 000 and R 5 000, which tended to vary across the different ethnic groups studied. After three or more years, the estimated financial capital of the majority (39.3%) of the respondents moved to a new range of R 50 001 - R 100 000. Noting a disparity in capital growth exhibited by the different ethnic groups, it was found that all the Ethiopians who started with a capital within the range of R1 000-R5 000 moved into a new capital range (R50 001-R100 000) three or more years after business start-up. Although, the absolute migration in terms of capital demonstrated by the Ethiopian is not in the highest capital range, they were nonetheless the only country that experienced this phenomenal growth. In terms of occupying the highest capital range (R250 001- R500 000) 11.1% of Cameroonians moved into that range followed by 7.4% of Somalians. Using an increase in financial capital (generated by ploughing back profits) as a proxy for growth, we were able to prove that these African immigrant-owned businesses grow and the rate of growth varied across the different ethnic groups studied.

South African law currently forbids those seeking to arrange a surrogate motherhood agreement from creating a child that will not be genetically related to at least one of them. For a surrogacy contract to be legally valid, there must be a ‘genetic link’ between the child created through a surrogate and the parents who will raise it. Currently, this law is being challenged in the High Court of South Africa, and in this article I critically explore salient (...) ethical facets of the dispute. I argue that the law is unjust and should be revised. (shrink)

Hirji’s book, somewhat overlooked since its release, offers a compelling analysis of the history and sociology of the sciences in Tanzania, with a focus on Hirji’s own field of statistics, from the post-independence period through to the 2010s. The first chapter provides an overview of Hirji’s career as a teacher. The second presents an account of Hirji’s experiences as a teacher under training, especially in light of the Arusha Declaration of 1967 and the turn towards building socialism in Tanzania, and (...) the philosophy of education for self-reliance that Nyerere attempted to institutionalize. The next four chapters provide a detailed account of Hirji’s years as a teacher at the University of Dar Es Salaam (UDSM) from 1971 until his dismissal and internal-exile in 1974. (shrink)

Using incoming revenues and the associated costs that underpin the concept of breakeven analysis, this article investigates the business survival strategies of immigrant-own-businesses in the context of African immigrants in the Cape Town Metropolitan Area of South Africa, and proposes a framework for the start-up survival of these businesses. The study was designed within the quantitative and qualitative research paradigms. A triangulation of three methods was utilised to collect and analyze the data. The research revealed that African (...) immigrant entrepreneurs face a range of challenges when starting their businesses and again as they try to grow or stay afloat. Furthermore, the study indicated that African immigrants rely more on certain entrepreneurial attributes as they seek innovative solutions to the problems that they encounter relating to business. As a business survival strategy, these immigrants develop a number of unconventional initiatives aimed at increasing sales revenue while minimising cost. (shrink)

Drawing a sample of 135 successful African immigrant-owned businesses, this paper sets out to investigate how their owners acquired the necessary capital for start-up and growth thereafter. The paper was designed within the quantitative and qualitative research paradigms, in which a triangulation of three methods was utilised to collect and analyze the data. The paper revealed that although African immigrants are characteristically at a disadvantage when it comes to accessing capital from formal financial institutions, this does not stop (...) them from pursuing entrepreneurial activities. At the start-up stage, they typically resort to personal savings, business credit, family credit, and loans from informal financial institutions. According to the ability to raise capital, we found that a varying range of start-up capital was utilised, which tended to vary across the different ethnic groups studied. Once started, we found that the sources of additional finance available to these immigrants did not change significantly. They conventionally turned to friends, co-ethnics and self-help financial associations to ‘feed’ their need for further funding. (shrink)

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.
