In the field of germline development in amniote vertebrates, primordial germ cell (PGC) specification in birds and reptiles remains controversial. Avians are believed to adopt a predetermination or maternal specification mode of PGC formation, contrary to an inductive mode employed by mammals and, supposedly, reptiles. Here, we revisit and review some key aspects of PGC development that channelled the current subdivision, and challenge the position of birds and reptiles as well as the ‘binary’ evolutionary model of PGC development in vertebrates. (...) We propose an alternative view on PGC specification where germ plasm plays a role in laying the foundation for the formation of PGC precursors (pPGC), but not necessarily of PGCs. Moreover, inductive mechanisms may be necessary for the transition from pPGCs to PGCs. Within this framework, the implementation of data from birds and reptiles could provide new insights on the evolution of PGC specification in amniotes. (shrink)

O objetivo do presente artigo consiste em apresentar uma reflexão sobre os paradigmas existentes e emergentes frente a um contexto teórico-científico e a necessidade de mudança devido aos desafios enfrentados em determinados momentos. Assim, o texto, de abordagem qualitativa e caracterizado como uma revisão bibliográfica, contextualiza acerca deste braço da filosofia que trata da natureza da pesquisa científica, do conhecimento no campo educacional, não somente do âmbito da epistemologia, mas também da fundamentação dos paradigmas das ciências e da educação, e (...) do conhecimento científico. As questões metodológicas estão diretamente relacionadas com essa reflexão sobre os resultados significativos e o que precisa ser modificado a partir de uma análise sobre o contexto social em que se está inserido. Para fundamentar este artigo, se apresentam as contextualizações que dialogam em torno de autores como Alda Judith Alves-Mazzotti, Pierre Bourdieu, Boaventura de Sousa Santos, Bernard Charlot, Edgar Morin, Thomas Kuhn e Mario Osório Marques. Portanto, o artigo expõe no seu panorama científico uma resposta às imposições das ciências na contemporaneidade, sem o rompimento com o passado e suas tradições, mas apresentando um olhar voltado para o futuro. A partir dessa perspectiva, precisamos ter clareza do campo científico em que estamos inseridos, conhecendo de fato suas peculiaridades para optarmos por um método que contemple as necessidades apresentadas, tendo segurança do que estamos fazendo. Enfim, pode-se concluir que os profissionais da educação precisam de uma base de pesquisa científica sólida para terem subsídios necessários ao experimentarem novas metodologias em suas práticas pedagógicas que sejam significativas para os estudantes.

Observations of animals engaging in apparently moral behavior have led academics and the public alike to ask whether morality is shared between humans and other animals. Some philosophers explicitly argue that morality is unique to humans, because moral agency requires capacities that are only demonstrated in our species. Other philosophers argue that some animals can participate in morality because they possess these capacities in a rudimentary form. Scientists have also joined the discussion, and their views are just as varied as (...) the philosophers’. Some research programs examine whether animals countenance specific human norms, such as fairness. Other research programs investigate the cognitive and affective capacities thought to be necessary for morality. There are two sets of concerns that can be raised by these debates. They sometimes suffer from there being no agreed upon theory of morality and no clear account of whether there is a demarcation between moral and social behavior; that is, they lack a proper philosophical foundation. They also sometimes suffer from there being disagreement about the psychological capacities evident in animals. Of these two sets of concerns—the nature of the moral and the scope of psychological capacities—we aim to take on only the second. In this chapter we defend the claim that animals have three sets of capacities that, on some views, are taken as necessary and foundational for moral judgment and action. These are capacities of care, capacities of autonomy, and normative capacities. Care, we argue, is widely found among social animals. Autonomy and normativity are more recent topics of empirical investigation, so while there is less evidence of these capacities at this point in our developing scientific knowledge, the current data is strongly suggestive.

These thirteen original essays, whose authors include some of the world's leading philosophers, examine themes from the work of the Cambridge philosopher G. E. Moore (1873-1958), and demonstrate his considerable continuing influence on philosophical debate. Part I bears on epistemological topics, such as skepticism about the external world, the significance of common sense, and theories of perception. Part II is devoted to themes in ethics, such as Moore's open question argument, his non-naturalism, utilitarianism, and his notion of organic unities.

Modern management reporting on its company''s performance is influenced by individuals ethical considerations. Stakeholders philosophies have continued to change over the last 75 years affecting reporting systems for companies reporting information internally and externally. These fundamental changes in philosophy have affected how information is conveyed. We are not claiming that only one philosophical viewpoint dominates companies reporting practices, but there does appear to be a changing trend of philosophies building on one another. We use resource dependence theory in relationship to (...) a decision-making model to explain changing stakeholders positions over time. This paper argues that six dominant philosophical theories have influenced the way individuals and organizations report financial and other information. Further, these philosophies then are depicted in a model that helps us to understand what influences companies to present themselves to the outside world. A vignette is used to depict changing philosophical views for several companies management report over 75 years. (shrink)

It has been argued that some animals are moral subjects, that is, beings who are capable of behaving on the basis of moral motivations. In this paper, we do not challenge this claim. Instead, we presuppose its plausibility in order to explore what ethical consequences follow from it. Using the capabilities approach, we argue that beings who are moral subjects are entitled to enjoy positive opportunities for the flourishing of their moral capabilities, and that the thwarting of these capabilities entails (...) a harm that cannot be fully explained in terms of hedonistic welfare. We explore the implications of this idea for the assessment of current practices involving animals. (shrink)

[Ronald de Sousa] Taking literally the concept of emotional truth requires breaking the monopoly on truth of belief-like states. To this end, I look to perceptions for a model of non-propositional states that might be true or false, and to desires for a model of propositional attitudes the norm of which is other than the semantic satisfaction of their propositional object. Those models inspire a conception of generic truth, which can admit of degrees for analogue representations such as emotions; (...) belief-like states, by contrast, are digital representations. I argue that the gravest problem-objectivity-is not insurmountable. /// [Adam Morton ] It is accuracy rather than truth itself that is valuable. Emotional truth is a dubious though attractive notion, but emotional accuracy is much easier to make sense of. My approach to accuracy goes via an account of what makes a story accurate. Stories can be accurate but not true, and emotions can be accurate whether or not they are true. The capacity for emotional accuracy, for emotions that fit a person's situation, is an aspect of emotional intelligence, which is as important an aspect of rational human agency as the intelligent formation of beliefs and desires.

It is generally assumed that humans are the only animals who can possess a concept of death. However, the ubiquity of death in nature and the evolutionary advantages that would come with an understanding of death provide two prima facie reasons for doubting this assumption. In this paper, my intention is not to defend that animals of this or that nonhuman species possess a concept of death, but rather to examine how we could go about empirically determining whether animals can (...) have a concept of death. In order to answer this question, I begin by sketching an account of concept possession that favours intensional classification rather than mere extensional discrimination. Further, I argue that the concept of death should be construed as neither binary nor universal. I then present a proposal for a set of minimal conditions that must be met to have a concept of death. I argue that having a minimal understanding of death entails first expecting a dead individual to be alive, and then grasping its non-functionality and irreversibility. Lastly, I lay out the sort of observational and experimental evidence that we should look for to determine whether animals have the capacity for a minimal comprehension of death. (shrink)

Este trabajo muestra cómo una modificación en el sentido del término caracter adquirido llevó a rechazar la hipótesis de la herencia de esos caracteres. Se considerará el ejemplo del experimento llevado a cabo por Weismann que fue tomado como un caso paradigmático en los libros de textos y en la bibliografía especializada para refutar esa hipótesis. Ese diseño experimental fue aceptado por la comunidad como una refutación, a pesar de que los caracteres a los que hacía referencia no cumplían con (...) ninguna de las condiciones necesarias para poder ser considerado un carácter adquirido. Así, quedó establecida la premisa de que sólo las células germinales podían heredarse fundándose lo que se conoció como la barrera de Weismann. Este caso pretende poner en consideración cómo la enseñanza y reproducción de los términos científicos y de sus indicadores puede llevar a limitar el desarrollo de las teorías. Se concluye acerca de la necesidad de reflexionar sobre la manera en que se citan y enseñan las teorías científicas a fin de evitar barreras en el desarrollo de los campos disciplinares. (shrink)

DERECHO DE RESPUESTA COMO FORMADOR DE OPINIÓN PÚBLICA: La jurisprudencia norteamericana y su relación con la argentina.

In this urbane and witty book, Ronald de Sousa disputes the widespread notion that reason and emotion are natural antagonists.

Could animals behave morally if they can’t mindread? Does morality require mindreading capacities? Moral psychologists believe mindreading is contingently involved in moral judgements. Moral philosophers argue that moral behaviour necessarily requires the possession of mindreading capacities. In this paper, I argue that, while the former may be right, the latter are mistaken. Using the example of empathy, I show that animals with no mindreading capacities could behave on the basis of emotions that possess an identifiable moral content. Therefore, at least (...) one type of moral motivation does not require mindreading. This means that, a priori, non-mindreading animals can be moral. (shrink)

Resenha do livro The Ethics of Environmentally Responsible Health Care.

In this paper, we argue that scientists working on the animal morality debate have been operating with a narrow view of morality that prematurely limits the variety of moral practices that animals may be capable of. We show how this bias can be partially corrected by paying more attention to the touch behaviours of animals. We argue that a careful examination of the ways in which animals engage in and navigate touch interactions can shed new light on current debates on (...) animal morality, like the study of consolation behaviour, while also revealing further forms that animal morality may take and that have been neglected so far, like capacities of tolerance or trust. This defence is structured as an analysis of the three main functions of touch: the discriminative function, the affiliative function, and the vigilance function. (shrink)

It is tempting to assume that being a moral creature requires the capacity to attribute mental states to others, because a creature cannot be moral unless she is capable of comprehending how her actions can have an impact on the well-being of those around her. If this assumption were true, then mere behaviour readers could never qualify as moral, for they are incapable of conceptualising mental states and attributing them to others. In this paper, I argue against such an assumption (...) by discussing the specific case of empathy. I present a characterisation of empathy that would not require an ability to attribute mental states to others, but would nevertheless allow the creature who possessed it to qualify as a moral being. Provided certain conditions are met, a behaviour reader could be motivated to act by this form of empathy, and this means that behaviour readers could be moral. The case for animal morality, I shall argue, is therefore independent of the case for animal mindreading. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

Comparative thanatologists study the responses to the dead and the dying in nonhuman animals. Despite the wide variety of thanatological behaviours that have been documented in several different species, comparative thanatologists assume that the concept of death is very difficult to acquire and will be a rare cognitive feat once we move past the human species. In this paper, we argue that this assumption is based on two forms of anthropocentrism: an intellectual anthropocentrism, which leads to an over-intellectualisation of the (...) CoD, and an emotional anthropocentrism, which yields an excessive focus on grief as a reaction to death. Contrary to what these two forms of anthropocentrism suggest, we argue that the CoD requires relatively little cognitive complexity and that it can emerge independently from mourning behaviour. Moreover, if we turn towards the natural world, we can see that the minimal cognitive requirements for a CoD are in fact met by many nonhuman species and there are multiple learning pathways and opportunities for animals in the wild to develop a CoD. This allows us to conclude that the CoD will be relatively easy to acquire and, so, we can expect it to be fairly common in nature. (shrink)

The interest of assigning homework is frequently discussed due to its alleged low impact on student achievement. One of the current lines of research is to emphasize the quality of student homework engagement rather than the amount of time spent on homework. The aim of this study was to determine (a) the extent to which students’ prior achievement affects their homework engagement (i.e., time spent, time management, and amount of teacher-assigned homework done), and (b) how students’ intrinsic motivation towards homework (...) may mediate or moderate the relationship between prior achievement and the homework engagement variables. A large sample of students from the first four years of Secondary Education (N = 1899) completed questionnaires. The results showed that intrinsic motivation partially mediates, but does not moderate, the effect of prior achievement on the three variables related to homework engagement (time spent, time management, and amount of teacher-assigned homework done). These results highlight the importance of considering both students’ current level of achievement and their motivation towards homework engagement when assigning homework. (shrink)
