RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE OS CISTOS OVARIANOS EM VACAS Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 11. CISTOS OVÁRICOS Os cistos são cavidades anormais que às vezes possuem conteúdo de fluido biológico, ou podem ser cavidades ocas, com paredes sólidas refratárias à maioria dos compostos endógenos. Formam-se como alterações patológicas das células luteais ou foliculares do estroma ovárico. A presença de cistos altera o ciclo estral e obriga a (...) realização de tratamentos exógenos para remover o mesmo, fazendo com que a atividade cíclica da gônada retome sua normalidade (HATLER, et al. 2006). Alguns fatores de origem nutricional, tanto por deficiência de alguns compostos, como por excesso no fornecimento de outros, têm sido considerados como causas potenciais dos cistos, entre os principais fatores nutricionais podemos citar: 11.1 Fito-toxidade/fitoestrogênios Compostos vegetais, tais como plantas com elevado teor de flavonoides estrogênicos, encontram-se sob a forma de glicosídeos e têm a capacidade para modificar os processos reprodutivos devido à sua semelhança com os núcleos esteroides de hormônios femininos; são substâncias estruturais e funcionalmente semelhantes ao 17-ß-estradiol ou que produz efeitos estrogênicos (MENDOZA, et al. 2001). Pouco se sabe sobre os estrogênios presentes nas plantas e os níveis de fito-toxidade dos mesmos, logo na prática torna-se algo difícil de ser observado e atacado. Porém, a nível laboratorial, caso haja alguma complicação que afete o animal para além das capacidades reprodutivas, um diagnóstico aprofundado é o mais indicado. 11.2 Minerais 11.2.1 Iodo (I) Alimentos com baixo teor de iodo, provocam estros silenciosos nos animais e aumentam a incidência de quistos ováricos. O I é parte da molécula de tiroxina que estimula a produção de ATP na mitocôndria, a deficiência reduz a captação de oxigênio o que determina uma diminuição no metabolismo energético. Na tireoide existe um complexo de proteína-iodo, chamado tiroglobulina, essa molécula é uma glicoproteína. A maioria do I é reduzida a iodo inorgânico no trato gastrointestinal e a sua absorção é imediata. A função principal da tireoide é acumular I e fixá-lo, formando hormônios da tireoide sob o controle da adenohipófise por secreção (TSH). O I é convertido em iodeto no trato intestinal e então é transportado para a tireoide, aqui as células foliculares o prendem com efetividade através de um processo de transporte ativo, contra um gradiente de concentração, estimulado por TSH. Uma vez que as hormonas da tireoide controlam o metabolismo, uma deficiência em I diminui a taxa metabólica do organismo, isso afeta indiretamente a reprodução, uma vez que o funcionamento irregular da tireoide afeta a formação de lipídios, esses necessários para a produção de hormônios esteroides (estrogênios) e estes por sua vez influenciam a síntese das prostaglandinas F2-alfa necessária para o processo de luteólise o que faz com que o corpo lúteo não se rompa, perdure e forme um cisto. O I presente no alimento do animal deve estar presente e obedecer o intervalo de 0,34 a 0,88 mg/kg de MS em todos os alimentos que o animal viera a ingerir, seja forragens ou rações. A forma de suplementação são as mais conhecidas, via volumoso, concentrado, água ou pelo sistema SMI. 11.2.2 Manganês (Mn) Níveis elevados de manganês na dieta levam à depleção da absorção de ferro, bem como de outros minerais necessários para a síntese, metabolismo, ativação de enzimas e absorção de outros minerais. Essas interações com outros minerais e o papel do excesso de manganês na inibição da síntese dos precursores de hormonas necessárias para a reprodução, bem como dos metabolitos gerados durante o desdobramento ruminal são representados de forma indireta. Para além do efeito antagônico com outros minerais e enzimas, níveis elevados de manganês provocam uma alteração na população da flora ruminal, o que prejudica a produção de ácido propiônico e butírico a nível ruminal, tendo um efeito negativo no metabolismo dos lipídios com uma subsequente baixa de energia (derivado do metabolismo graxo diminuído ou inibido) e também da síntese de ácidos graxos. Por esta última razão, ocorre uma diminuição na síntese das hormonas esteroides, as quais, não estando presentes em níveis adequados, geram problemas no ciclo estral, uma vez que estas hormonas são essenciais para a síntese das prostaglandinas (PGF2-α) que são necessários para a lise do corpo lúteo, com sua posterior persistência, terminando na formação de um cisto luteal. Como sempre falado nos capítulos dessa compilação de trabalhos, o composto Mn é mais um mineral imprescindível para a alimentação do animal, manutenção normal dos seus mecanismos fisiológicos e relações com outros minerais. Sua disponibilidade para o animal deve ser de 12 a 50 mg/kg de MS das forragens, ou a mesma quantidade no conteúdo da ração balanceada. É um elemento que pode ser colocado na água para absorção pelos animais ou através da suplementação mineral injetável (SMI). 11.2.3 Sódio (Na) Os sinais de deficiência de Na são inespecíficos, mas os mais expressivos são sobre o crescimento e produção leiteira. Numa diminuição do consumo de Na, o organismo ativa os mecanismos de conservação mediados pela liberação de aldosterona que aumenta a reabsorção a nível dos túmulos renais deste mineral. A deficiência de Na afeta a produção de muco cervical, com consequências como problemas na formação de espermatozoides e aumento das infecções uterinas. Dado que a deficiência de Na é rara, apenas os sintomas clínicos desta deficiência mineral podem ser vagamente descritos é k caso da dificuldade de concepção, distorcias e bezerros fracos ao nascimento, além da inatividade ovárica e maior incidência de retenção de placenta. As causas de tais alterações foram motivo de numerosos estudos com resultados contraditórios, as vacas com deficiência de energia no início da amamentação têm diminuição nas concentrações de hormona luteinizante (LH), isto conclui que a alteração ovárica seria determinada por uma alteração da liberação pulsátil de LH devido a uma deficiência energética aguda. A intensidade e a duração do estro são de importância fundamental para a IA nos bovinos. Ao ocorrer uma deficiência de sódio, aumenta-se a estabilização das membranas celulares impedindo que o corpo lúteo se lise, formando-se um cisto, que continuará com a produção de progesterona, levando, por fim, a um anestro patológico. O sódio é um elemento que deve estar disponível aos animais de forma à vontade, ou seja, esse mineral é combinado com o Cl, fazendo o balanceamento eletrolítico e disponibilizado para os animais pelo conhecido sal. Sua administração, como é em sistema à vontade, não é muito controlada, mas o produtor poderá fornecer as quantidades na mistura alimentar do animal, tendo um maior controle da absorção do mesmo pelos animais. Sendo assim, o Na deve ser fornecido em quantidades que obedeçam 0,10 a 0,18% da MS no caso das forrageiras, ou a mesma quantidade misturada no todo da ração, quantidade essa encontrada por meios de cálculos, ou que já vêm na composição da ração industrial. Estudos apontam que um animal deve ingerir cerca de 50 gramas de NaCl por dia, no caso do sódio estar presente em 39% da composição desse cloreto de sódio.

The COVID-19 pandemic highlighted the importance of internet access across various aspects of life, from remote work and online education to healthcare services and social connections. As we transition to a post-pandemic era, a pressing need arises to update our understanding of the multifaceted nature of internet access. This study is one of the first attempts to do so. Using survey data from New Zealand adult internet users (n=960), it compares internet connection types, frequency of internet use at home, social (...) media use, and concerns about online risk between people with and without disabilities. Results show people with disabilities have restricted fibre access and higher wireless broadband (a much slower connection type). People with disabilities use social media platforms less and are more concerned about certain online risks. The findings highlight persistent disparities in internet access for people with disabilities in the post-pandemic era. Implications of the study are discussed. (shrink)

El libro "E-physicalism - A Physicalist Theory of Phenomenal Consciousness" presenta una teoría en el área de la metafísica de la conciencia fenomenal. Está basada en las convicciones de que la experiencia subjetiva -en el sentido de Nagel - es un fenómeno real, y de que alguna variante del fisicalismo debe ser verdadera.

The aim of this paper is to explore the peculiar case of infectious logics, a group of systems obtained generalizing the semantic behavior characteristic of the -fragment of the logics of nonsense, such as the ones due to Bochvar and Halldén, among others. Here, we extend these logics with classical negations, and we furthermore show that some of these extended systems can be properly regarded as logics of formal inconsistency and logics of formal undeterminedness.

Introduction to the Special Volume, “Method, Science and Mathematics: Neo-Kantianism and Analytic Philosophy,” edited by Scott Edgar and Lydia Patton. At its core, analytic philosophy concerns urgent questions about philosophy’s relation to the formal and empirical sciences, questions about philosophy’s relation to psychology and the social sciences, and ultimately questions about philosophy’s place in a broader cultural landscape. This picture of analytic philosophy shapes this collection’s focus on the history of the philosophy of mathematics, physics, and psychology. The following (...) essays uncover, reflect on, and exemplify modes of philosophy that are engaged with these allied disciplines. They make the case that, to the extent that analytic philosophers are still concerned with philosophy’s ties to these disciplines, we would do well to pay attention to neo-Kantian views on those ties.

While children’s experiences of online risks and harm is a growing area of research in New Zealand, public discussion on the matter has largely been informed by mainstream media’s fixation on the dangers of technology. At best, debate on risks online has relied on overseas evidence. However, insights reflecting the New Zealand context and based on representative data are still needed to guide policy discussion, create awareness, and inform the implementation of prevention and support programmes for children. This research report (...) presents findings from a quantitative study regarding different aspects related to risks and online safety. It looks at the online experiences that children find bothersome and upsetting and explores the hurtful behaviours they encounter or engage in, both online and in person. Evidence regarding exposure to different types of potentially harmful online content is also presented. Another relevant contribution is the insights related to excessive internet use.The findings presented in this report are based on data from 2,061 New Zealand children aged 9-17. We hope the findings will contribute to the development of policies, practices and services designed to support New Zealand children to safely take advantage of the opportunities available to them online.

Consider the claims that representations of physical laws are intersubjective, and that they ultimately provide the foundation for all other intersubjective knowledge. Those claims, as well as the deeper philosophical commitments that justify them, constitute rare points of agreement between the Marburg School neo-Kantians Paul Natorp and Ernst Cassirer and their positivist rival, Ernst Mach. This is surprising, since Natorp and Cassirer are both often at pains to distinguish their theories of natural scientific knowledge from positivist views like Mach’s, and (...) often from Mach’s views in particular. Thus the very fact of this agreement between the Marburg School neo-Kantians and their positivist stalking horse points to a deep current of ideas that runs beneath the whole of the post-Kantian intellectual context they shared.

In her paper, The case for physician assisted suicide: not proven, Bonnie Steinbock argues that the experience with Oregon’s Death with Dignity Act fails to demonstrate that the benefits of legalising physician assisted suicide outweigh its risks. Given that her verdict is based on a small number of highly controversial cases that will most likely occur under any regime of legally implemented safeguards, she renders it virtually impossible to prove the case for physician assisted suicide. In this brief paper, we (...) suggest some ways that may enable us to weigh the risks and benefits of legalisation more fairly and, hopefully, allow us to close the case for physician assisted suicide.

Research and practice about self-determination in the context of disability has centred on teaching skills and providing support to help people with impairments to be independent. However, limited research exists about the impact of Information and Communication Technologies, in particular social media and mobile devices, on the development of self-determination skills among people with disabilities. This paper presents the findings of a qualitative study which collected data from observations, a researcher diary, focus groups, individual interviews and data from social media. (...) The focus of the study was on young people with vision impairments who were transitioning to university life. The study found that the participants developed self-determination skills by using and adapting collaborative and interactive online tools and mobile devices according to their transition needs. This finding expands the understanding of the implications of new technologies for young people with disabilities’ personal development and the enhancement of self-determination. (shrink)

To explore social media use in New Zealand, a sample of 1001 adults aged 18 and over were surveyed in November 2021. Participants were asked about the frequency of their use of different social media platforms (text message included). This report describes how often each of the nine social media sites and apps covered in the survey are used individually on a daily basis. Differences based on key demographics, i.e., age and gender, are tested for statistical significance, and findings summarised.

In Bertrand Russell's 1903 Principles of Mathematics, he offers an apparently devastating criticism of the neo-Kantian Hermann Cohen's Principle of the Infinitesimal Method and its History (PIM). Russell's criticism is motivated by his concern that Cohen's account of the foundations of calculus saddles mathematics with the paradoxes of the infinitesimal and continuum, and thus threatens the very idea of mathematical truth. This paper defends Cohen against that objection of Russell's, and argues that properly understood, Cohen's views of limits and infinitesimals (...) do not entail the paradoxes of the infinitesimal and continuum. Essential to that defense is an interpretation, developed in the paper, of Cohen's positions in the PIM as deeply rationalist. The interest in developing this interpretation is not just that it reveals how Cohen's views in the PIM avoid the paradoxes of the infinitesimal and continuum. It also reveals some of what is at stake, both historically and philosophically, in Russell's criticism of Cohen. (shrink)

Many conservatives endorse a defence of closed borders grounded in basic liberal rights such as the basic right of association. Some conservatives also endorse libertarian principles of legitimacy. It is not clear though that this sort of defence of closed borders is somehow coherent with these libertarian ideals. I argue that conservative libertarians of this kind must reject this defence of closed borders because either it collapses into a form of statism incoherent with libertarian principles of legitimacy, or into an (...) ideal precept without appeal regarding reality in the here and now that could only be applied to changing the very nature of the societies we know. As a result, at least conservative libertarians need to find a different source of justification for closed borders. (shrink)

This research report presents findings about the extent and nature of digital self-harm among New Zealand teens. Digital self-harm is broadly defined here as the anonymous online posting or sharing of mean or negative online content about oneself. The report centres on the prevalence of digital self-harm (or self-cyberbullying) among New Zealand teens (aged 13-17), the motivations, and outcomes related to engaging in this behaviour. The findings described in this report are representative of the teenage population of New Zealand by (...) gender, ethnicity and age. Key findings are: Overall, 6% of New Zealand teens have anonymously posted mean or negative content online about themselves in the past year. Teenagers’ top reasons for this behaviour were: making a joke, wanting to show resilience, looking for friends’ sympathy, and seeking reassurance of friendship. By exploring the nature and extent of this behaviour, we are providing the online safety community, schools and parents with insights about a complex and, to some extent, hidden phenomenon involving New Zealand teens.

Over the last ten years the sharing of nude images or videos (sometimes known as “sexting”) by young people has emerged as a concern. Despite this, no research had been conducted on the prevalence of the sharing of nudes among young New Zealanders. This study addresses this and raises important questions for all those with a role in supporting young people’s healthy development. We believe this report makes an important contribution to the overall understanding of young people’s experience of these (...) behaviours. However, it only provides a snapshot, and more work is required to understand how best to support young people as they navigate the challenges and potential risks. This report is being released as part of a larger project exploring young people’s experiences of digital risk and harm, carried out by a partnership between Netsafe and the Ministry for Women.

The physiologist Johannes Müller’s doctrine of specific nerve energies had a decisive influence on neo-Kantian conceptions of the objectivity of knowledge in the 1850s - 1870s. In the first half of the nineteenth century, Müller amassed a body of experimental evidence to support his doctrine, according to which the character of our sensations is determined by the structures of our own sensory nerves, and not by the external objects that cause the sensations. Neo-Kantians such as Hermann von Helmholtz, F.A. Lange, (...) and Otto Liebmann took Müller’s doctrine to have far-reaching consequences for their epistemologies. Over the course of the 1850s - 1870s, these three neo-Kantians, each in his own way, argued that reflection on Müller’s doctrine ruled out a certain conception of the objectivity of knowledge. It ruled out the view that knowledge is objective in virtue of affording us information about objects in a mind-independent external world. -/- This paper traces how Helmholtz, Lange, and Liebmann developed their arguments for this view, and how each developed his own alternative conception of objectivity, according to which objectivity has nothing to do with a mind-independent world. Finally, the paper concludes by considering why these arguments modelled on Müller’s doctrine would have been so powerful against rival post-Hegelian conceptions of objectivity, especially those of scientific materialists like Ludwig Büchner.

While children’s interaction with digital technologies is a matter of interest around the world, evidence based on nationally representative data about how integrated these tools are in children’s everyday life is still limited in New Zealand. This research report presents findings from a study that explores children’s internet access, online skills, practices, and opportunities. This report is part of Netsafe’s research project Ngā taiohi matihiko o Aotearoa - New Zealand Kids Online, and our first publication as a member of Global (...) Kids Online. Generating insightful, reliable evidence about New Zealand children’s online experiences is vital to develop adequate support that reflects children’s experiences and needs. This, in turn, will help them to manage online risks and potential harm from behaviours such as cyberbullying, harassment, and other forms of abuse and intimidation. (shrink)

About thirty years ago, when the Internet started to be commercialised, access to the medium became a topic of research and debate. Up-to-date evidence about key predictors, such as age, is crucial because of the Internet's ever-changing nature and the challenges associated with gaining access to it. This paper aims to give an overview of New Zealand's Internet access trends and how they relate to age. It is based on secondary analysis of data from a larger online panel survey with (...) 1,001 adult respondents. The Chi-square test of independence and Cramer's V were used in the analysis. The study provides new evidence to understand the digital divide. Specifically, it uncovers a growing disparity in the quality of Internet connectivity. Even though fibre is the most common type of broadband connection at home, older adults are less likely to have it and more likely to use wireless broadband, which is a slower connection type. Additionally, a sizable majority of people in all age categories have favourable opinions on the Internet. Interestingly, this was more prevalent among older people, although they report an increased concern about the security of their personal information online. The implications of the results are discussed and some directions for future research are proposed. (shrink)

Research on transition to higher education and young people with disabilities has increased in recent years. However, there is still limited understanding of transition issues and how digital technologies, such as social media and mobile devices, are used by this group of students to manage these issues. This article presents the findings of an empirical study that addressed this matter based on young people’s views and experiences. The qualitative study was conducted in the context of a group of students with (...) vision impairments transitioning to a New Zealand university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The study shows that, like their non-disabled peers, the students actively engaged with interactive and collaborative digital technologies to make sense, individually and collectively, of different transition issues before, during and after the first academic trimester of their university journey.

Some commentators on Hermann Cohen have remarked on what they take to be a puzzle about the origins of his mature anti-psychologism. When Cohen was young, he studied a kind of psychology, the Völkerpsychologie of Moritz Lazarus and Heymann Steinthal, and wrote apparently psycholgistic accounts of knowledge almost up until the moment he first articulated his anti-psychologistic neo-Kantianism. To be sure, Cohen's mature anti psycholgism does constitute a rejection of certain central commitments of Völkerpsychologie. However, the relation between Völkerpsychologie and (...) Cohen's mature anti-psychologism is not one of straightforward opposition. This paper argues that Cohen had significantly less distance to travel than it appears to get from his early Völkerpsychologie to his mature anti-psychologism. In particular, this paper argues that Cohen always had an anti-psychologistic account of knowledge, even during the period when he was studying Völkerpsychologie, and further, that key features of his Völkerpsychologie partly shaped his mature account of knowledge. Finally, the paper identifies how Cohen’s views did change over the transition from his völkerpsychological period to his later anti-psychologism. It thus identifies what changes in Cohen’s views do need to be explained. (shrink)

This paper considers George A. Reisch’s account of the role of Cold War political forces in shaping the apolitical stance that came to dominate philosophy of science in the late 1940s and 1950s. It argues that at least as early as the 1930s, Logical Empiricists such as Rudolf Carnap already held that philosophy of science could not properly have political aims, and further suggests that political forces alone cannot explain this view’s rise to dominance during the Cold War, since political (...) forces cannot explain why a philosophy of science with liberal democratic, anti-communist aims did not flourish. The paper then argues that if professionalization is understood in the right way, it might point toward an explanation of the apolitical stance of Cold War philosophy of science. (shrink)

This translation of Enrique Dussel's “‘Ser-Hispano’: Un Mundo en el ‘Border’ de Muchos Mundos” offers an interpretation of hispanos (Latin Americans and U.S. latinos) as historically, culturally, and geographically located “in-between” many worlds that combine to constitute an identity on the intercultural “border.” To illustrate how hispanos have navigated and continue to navigate their complex history in order to create a polyphonic identity, the essay sketches five historical-cultural “worlds” that come together to form the hispanic “world.”.

Nationalism seems a persistent ideology in academia as much as in politics; despite the fact that it has been shown that nationalism is deeply unjust for minorities. A case for national identity is often invoked to supplement liberalism regarding the inner difficulties that liberal theories have to explain their membership, assure stability and produce endorsement. So, it seems that national identity may also be required for justice. While this controversy continues, I argue that a different approach is available. We can (...) define a conception of legitimacy independently from a conception of justice, and then ask what legitimacy requires from our national allegiances. If everything goes well, much of the controversy from justice disappears as we find that the case for cultural nationalism may be illegitimate for liberal democracies. (shrink)

A growing number of young people with disabilities is pursuing university education. Available research on the impact of Information and Communication Technologies on this matter has mainly focused on assistive technologies and their compensatory role for the adjustment of this group of students to the tertiary setting. However, limited research has looked at the role played by digital technologies such as social media and mobile devices in the transition to university, a critical period of change for all students but more (...) challenging for those with impairments. This paper presents the findings of an empirical study that investigated the experiences of students with vision impairments aged 18 to 24 who were transitioning to a New Zealand university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The study found that new technologies play several enabling roles that help students to manage diverse transition challenges. These roles not only include aspects such as impairment compensation, communication, information, and learning but also support arrangement, collaboration, and social connection and participation. By incorporating in the analysis the potential of digital tools, the article updates and expands the understanding of the role of ICTs in higher education from experiences and views of young people with vision impairments.

The transport sector is one of the largest sources of greenhouse gas emissions in New Zealand. To address this issue, the government is planning a set of actions to be implemented in the next 15 years. One of these actions deals with transport emissions and targets for a reduction in light vehicle travel. However, to achieve this goal, there is a need for both an updated assessment of effective interventions and an analysis of their relevance and applicability to the New (...) Zealand context. This report seeks to close the gap by conducting a narrative literature review of a collection of existing literature, supplemented with some targeted searches. With the focus on evidence relevant to New Zealand’s largest and fastest growing urban environments, the report identified 24 publicly available research outputs from around the world (mainly from Western European countries). The papers assessed differ not only in the type of research method and analysis applied but also the form of intervention (s) evaluated, the duration of the intervention and follow-up periods, the characteristics of the population groups or intervention sites studied, the measures, results and metrics relevant to New Zealand, and the outcomes of the interventions. Although these differences may represent a challenge in terms of comparability and transferability, they also provide opportunities and lessons for policy-and decision-makers. Finally, the report discusses the implications of the review and its findings and provides some directions and recommendations for future research, policy and practice for the measurement and evaluation of interventions.

In its recent statement 'Sex Selection and Preimplantation Genetic Diagnosis', the Ethics Committee of the American Society of Reproductive Medicine concluded that preimplantation genetic diagnosis for sex selection for non-medical reasons should be discouraged because it poses a risk of unwarranted gender bias, social harm, and results in the diversion of medical resources from genuine medical need. We critically examine the arguments presented against sex selection using preimplantation genetic diagnosis. We argue that sex selection should be available, at least within (...) privately funded health care. (shrink)

This article introduces Transition 2.0, a paradigm shift designed to study and support students with disabilities' transition to higher education. Transition 2.0 is the result of a qualitative study about how a group of young people with vision impairments used digital technologies for their transition to university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The article discusses a conventional view of transition, referred to here as Transition 1.0, which has dominated (...) disability-related research and service provision in higher education. It counters this view by further developing the conceptual framework for Transition 2.0. The findings expand current conceptual approaches to transition by incorporating in the analysis the role played by digital tools such as social media and mobile devices. They also provide a new lens through which to study and understand student engagement in higher education. (shrink)

Are there any truly ontologically random events? This paper argues that randomness is an unavoidably epistemic concept and therefore ascription of ontological randomness to any particular event or series of events can never be justified.

The nature and extent of adults’ engagement in diverse manifestations of technology-facilitated aggression is not yet well understood. Most research has focused on victimization. When explored, engagement in online aggression and abuse has centered on children and young people, particularly in school and higher education settings. Drawing on nationally representative data from New Zealand adults aged 18 and over, this chapter explores the overall prevalence of online aggression with a focus on gender and age. Our findings support the need to (...) also understand adult aggressors’ behaviors to better address the distress and harm caused to targets through digital communications. The chapter discusses the implications of the results for policy and practice and proposes some directions for future research. (shrink)

Since transition to higher education emerged as a research topic in the early 1970s, scholarly inquiry has focused on students without impairments and, what is more, little attention has been paid to the role of digital technologies. This article seeks to address this knowledge gap by looking at the university experiences of a group of first-year students with vision impairments from New Zealand, and the way they use digital tools, such as social media and mobile devices, to manage their transition-related (...) challenges. The article summarises the findings from a longitudinal qualitative project which was methodologically informed by action research (AR). The article explores and discusses scholarly inquiry of transition to university and introduces a conceptual framework which includes five overlapping stages, the transition issues faced by the students and the roles played by digital technologies. The article updates and expands the theoretical understanding of transition to higher education and provides empirical evidence for practitioners to support the needs, inclusion, and participation of young people with disabilities in the tertiary setting.

ABSTRACT A number of authors have recently advanced a ‘disjunctivist’ view of the rationalising explanation of action, on which rationalisations of the form ‘S A’d because p’ are explanations of a fundamentally different kind from rationalisations of the form ‘S A’d because she believed that p’. Less attempt has been made to explicitly articulate the case against this view. This paper seeks to remedy that situation. I develop a detailed version of what I take to be the basic argument against (...) disjunctivism, drawing on a framework of explanatory proportionality. The disjunctivist cannot reject this framework, I argue, because they need it to respond to another challenge, from psychological individualism. As I explain, however, the proportionality-based challenge is not in principle insurmountable, and I outline a number of ways in which a case for disjunctivism might be developed in response to it. The paper thus clarifies the dialectic around disjunctivism about the rationalisation of action and, specifically, what advocates of the view must do in order to make a compelling case for it.

Research suggests that parents tend to largely underestimate their child’s engagement in risky and/or hurtful behaviours as well as their experiences of harm online. While helpful, the available international evidence is not only limited but also does not reflect the New Zealand context. In addition, understanding parental knowledge of the online experiences of children is important as parents play a critical role in helping their child to prevent or deal with bothering experiences and risky behaviours as well as providing children (...) with emotional support when things go wrong online. To help close the gap of New Zealand-based evidence on the topic, this factsheet presents findings from a quantitative study conducted with New Zealand parents and their children. The objectives of the study are to measure parental knowledge of children’s experiences of risks and harm online, and to compare parents’ level of awareness with their child’s self-reported experiences. The study found a mismatch between parents’, caregivers’ and whānau awareness and their children’s reports of bothering or upsetting experiences online. (shrink)

In 'Weak agnosticism defended' Graham Oppy set out to ’show that agnosticism can be so formulated that it is no less philosophically respectable than theism and atheism’. Oppy begins by differentiating between strong agnosticism, which obliges rational persons to suspend judgment on the question of God’s existence, and weak agnosticism, which allows rational persons to do so. Weak agnosticism is thus the philosophical position that it is possible and rational - but not obligatory - to suspend judgment on the question (...) of God’s existence. The question I discuss in this paper is whether one can consistently practice agnosticism, as opposed to merely suspending judgment regarding the existence of God? Does acceptance of the the sis that ’agnosticism can be so formulated that it is no less philosophically respectable than theism and atheism’ entail the possibility of actual consistent practice of agnosticism?

Brian Garrett claims, in defence of Gaunilo’s Perfect Island and contra Plantinga, that ‘Properly understood, the great-making qualities of an island are maximal’. This article demonstrates that they are not, thus ‘the greatest conceivable island’ remains an incoherent concept and Gaunilo’s parody fails.

Government agencies in New Zealand are not required to systematically collect data on online hate speech, thus, there is a lack of longitudinal evidence regarding this phenomenon. This report presents trends in personal experiences of and exposure to online hate speech among adult New Zealanders based on nationally representative data. The findings from this study are also compared with results from a similar research study conducted in 2018. In addition, this report explores people’s perceptions about other issues related to hate (...) speech. The goal of this study is to fill some knowledge gaps regarding the extent and nature of hate speech in New Zealand. It also seeks to provide reliable and robust evidence to inform public conversation on the topic and the implementation of strategies and activities to ensure all New Zealanders, no matter what their characteristics, are safe online to benefit from the multiple opportunities of the digital environment.

This paper aims to answer the question: what does the realism of laws of nature consist of? To achieve this, in the first part, three philosophical accounts of laws of nature are presented and examined: the universalist, the dispositionalist and the counter-factualist. The presentation and examination focuses on the answer given by each of these accounts to the question: what is a law of nature? Later, in the second part, convergences and divergences between these three accounts are shown. Finally, in (...) the third section, the points of agreement between them are put together to advance the fundamental thesis that encompasses each of these accounts as realist accounts of laws of nature. This thesis, I argue, is at the end the core of the general realist stance on laws of nature that I name “Realism of Laws of Nature”. (shrink)

El presente artículo reflexiona sobre los orígenes del pragmatismo atendiendo puntos importantes para implicaciones epistemológicas que buscan servir luego de clave para una perspectiva para el pensamiento del sur del continente. Hay una exposición de aspectos centrales que sobre el pragmatismo expuso Charles Pierce, específicamente sobre las creencias, el signo como mediación cognitiva, así como una consideración de las ciencias para comprender el papel tanto del razonamiento como de la percepción y el instinto. Igualmente, se exponen elementos claves de la (...) teoría del conocimiento de John Dewey, quien ante el rechazo declarado al racionalismo cartesiano y sin limitarse a la experiencia como punto de referencia para la clarificación conceptual, se encamina más a unas vivencias y contactos con un mundo observado comprometiendo así la realidad sentida la propia mente. El pragmatismo implica atención a lo que nos rodea sin generar separaciones entre sensibilidad y razón o entre pensamiento y emoción, lo cual hace que los asuntos de la ciencia y del conocimiento no se den ajenos a las acciones democráticas entre los individuos activos y sus colectivos.

In this paper I introduce some of the key elements of Daniel Dennett’s theory of intentional attribution and their relation with his notion of rationality. While doing so I will show that Dennett’s approach implies a circularity in the process of attribution of rationality, and that his resource to evolutionary arguments for trying to avoid an infinite regress does not help him to avoid the problem. My presentation will include a revision of Dennett’s arguments for epistemic intentional ascription and rationality (...) attribution as well as some criticisms developed against his proposal. At the end of the article I will extend the criticisms and present my view about his proposal for ideal rationality attribution. (shrink)

Moses deviced healthy laws to keep his people united as a nation. Moses is , alongside with Plato, Aristotle, Mahomet, Kung Fu, Lao Tse and Cicero, one of the "intelligent designers" of mankind in the last 5.000 years.

The text addresses the question ¿Where do bodies moves according to Spinoza´s physical scheme, as presented in his Ethics? The question holds a strong connection to the classical questioning by Oldenberg, about the way in which sigular objects acquire their individuality and how deos nature operate as a unity, despite its complex constitution. The answer will refer not just to Spinoza´s critique to cartesian mechanics, as it is usually referred, but to Spinoza´s own interpretation of the constitution and dynamics of (...) the physical world in order to fulfill the tasks it was designed for.

Framed within the development policies for the region, educational agendas for Latin America represent specific commitments that transcend the improvement in the results of specific tests permeating both pedagogical practices and conceptual frameworks in which these ones acquire meaning. This paper covers some of the commitments made by these agendas and develops the general framework in which participation of philosophical community is expected and required as a guarantor and promoter of the construction of spaces for reflection and action on educational (...) system.

The ancient Ouroboros symbolism (one who eats oneself) is here integrated into a simple birth-death clustering process that needed nothing but itself for a transition from indistinguishable phases to a sort of higher level ”conscious” phases. Birth and death coefficients are formulated in terms of odd and even exponentials used to represent a suitable form for conscious states via the internal transfer of information. This toy model may ideally quantify conscious states having inner causes via an Ouroboros index 0 < (...) Υα,Ω < 1. The value Υα,Ω = 0 lends to infinite loops and the limiting values Υα,Ω → 1 disclose transformation into awareness. Relationships with physics theories of consciousness and the use of the Oroborous index to discern about conscious-like states in Artificial Intelligence systems are discussed. Consciousness and freedom of will may go side-by-side in the model when Υα,Ω is extended to be a complex number modulus. (shrink)
