How is the embryonic bipotential gonad regulated to produce either an ovary or a testis? In males, transient early activation of the Y chromosome Sry gene makes both germ cells and soma male. However, in females, available evidence suggests that the process of ovary sex determination may take place independently in the germline and somatic lineages. In addition, in contrast to testis, in ovary somatic cells, female‐to‐male gonadal sex reversal can occur at times throughout ovary development and maturation. We suggest (...) that a single gene pathway, likely hinging on the Foxl2 transcription factor, both initiates and maintains sex differentiation in somatic cells of the mammalian ovary.

Desde una plataforma mental poco convencional, el enfoque del caos y la complejidad, el autor de este libro aventura una novedosa hipótesis interpretativa del fenómeno climático global. Plantea que la civilización del consumismo logró romper la dinámica natural de los ciclos orden caos, y abrió camino, durante la segunda mitad del siglo XX, a un segundo ciclo caos que podría llevarnos a la catástrofe que han advertido los científicos y estudiosos del tema.Manuel Guzmán Hennesy se plantea apor..

No presente artigo se apresenta uma análise do conceito marxiano de força de trabalho como uma categoria, um referente ideal geral de natureza teórica, cuja elaboração por Marx potencialmente faculta o rastreamento de traços essenciais para a compreensão crítica do caráter particular assumido pela individualidade nos contornos das formas de sociabilidade do capital. Nesse sentido, a discussão dos textos marxianos, bem como de obras de outros autores que abordam o tema ou questões conexas a este, tem como objetivo enumerar analiticamente, (...) de modo indiciário, as determinações que fazem da força de trabalho livre individual existente como mercadoria do capital uma verdadeira protoforma ou “paradigma” da individuação a partir da modernidade. Para tanto serão tratados quatro conjuntos conceituais, vetores da trajetória desse tipo histórico de elaboração social da individualidade, conforme pode se depreender do estudo das obras de Marx aqui abordadas: 1) a força de trabalho como Daseinsform do capital e força de sua produção; 2) o modo particular de alienação da força de trabalho (Veräußerung); 3) o caráter complexo do “objeto” do qual o capital se apropria; e 4) a relação que o indivíduo tem consigo mesmo como proprietário privado de força de trabalho.

The study of Buddhist texts can inform us of the way scriptures were composed, as well as illuminate the reasons behind their production. This study examines the phenomenon of borrowing and reusing portions of texts without attributing them to their ‘legitimate authors’ within the Buddhist world of contemporary Tibet. It shows that not only is such a practice not at all infrequent and is often socially accepted, but that it is used in this case as a platform to advance specific (...) claims and promote an explicit agenda. Therefore, rather than considering these as instances of plagiarism, this essay looks at the practice of copying and borrowing as an exercise in intertextuality, intended as the faithful retransmission of ancient truths, and as an indication of the public domain of texts in Tibet.

This paper develops the very basic notions of analysis in a weak second-order theory of arithmetic BTFA whose provably total functions are the polynomial time computable functions. We formalize within BTFA the real number system and the notion of a continuous real function of a real variable. The theory BTFA is able to prove the intermediate value theorem, wherefore it follows that the system of real numbers is a real closed ordered field. In the last section of the paper, we (...) show how to interpret the theory BTFA in Robinson's theory of arithmetic Q. This fact entails that the elementary theory of the real closed ordered fields is interpretable in Q. (shrink)

In this paper, we present a formal interpretive account of Jean Piaget’s theory of the morality that regulates social exchanges, which we call interactional morality. First, we place Piaget’s conception in the context of his epistemological and sociological works. Then, we review the core of that conception: the two types of interactional moralities that Piaget identified to be usual in social exchanges, and the role that the notion of respect-for-the-other plays in their definition. Next, we analyze the main features of (...) social exchanges that are subject to each of those two types of interactional moralities. Following, we formalize Piaget’s account of how the two types of interactional moralities can be put to regulate social exchanges in which values, norms, beliefs, and goals are exchanged, so that interactional commitments can be established among the participants. Then, we sketch a moral reasoning system able to support formal reasonings about interactional moralities. Finally, we illustrate the usefulness of the overall formal model of interactional moralities that resulted from our study by applying it to the explication of some of the conclusions achieved by Piaget in his moral studies about children games.

This study examines the personal values and value types of Chinese accounting practitioners and students, using the values survey questionnaire developed and validated by Schwartz (1992, Advances in Experimental Social Psychology 25, 1–65). A total of 454 accounting practitioners and 126 graduate accounting students participated in the study. The results show that Healthy, Family Security, Self-Respect, and Honoring of Parents and Elders are the top four values for both accounting practitioners and accounting students, although these values are not ranked in (...) the same order. Social Power, An Exciting Life, Devout, and Accepting My Portion in Life are the lowest rated four values for the accounting practitioners whereas Devout, An Exciting Life, Detachment, and Accepting My Portion in Life form the bottom four values for the accounting students. Both accounting practitioners and students ranked Security as the highest value type and Tradition as the lowest one, and the students rated Self-Direction as significantly more important than the practitioners. With respect to gender differences, both the male accounting practitioners and students rated the value type Achievement significantly higher than their female counterparts and there were several significant gender differences in personal values for both accounting practitioners and students. In addition, the perceived values are linked to social and cultural factors as well as to the influence of Western values. (shrink)

In the so-called digital culture, there is a constant presence of radical transformations on the cognitive and affective dimensions of the relations established among teachers and students. Upon this ubiquitous accessibility of information, the very historical and hierarchically verticalized relation between teachers and students has been increasingly questioned. Upon this situation, the authors in this article aim at stating that the revitalization of concepts developed by Paulo Freire, mainly the ones discussed in the books: ‘Pedagogy of Hope’, that sought a (...) re-encounter with ‘Pedagogy of the Oppressed’, ‘Extension or Communication’ and ‘Pedagogy of Freedom’ became essential to understanding how the relationship between teachers and students can be mutually re-signified. In these times of digital culture, we argue that the revitalization of the critical thinking proposed by Freire is able to foment a dialogical communication both in the pedagogical link shared by teachers and students and in the transformation of information into substantially and ethically experienced concepts. Such substantial and ethical experiences are the ones able to attest that the pedagogy of hope and the pedagogy of freedom are possible, provided they are constituted with the students and not for them.

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19.

This article integrates previously missing components of government quality into the governance-piracy nexus in exploring governance mechanisms by which global obligations for the treatment of IPRs are effectively transmitted from international to the national level in the battle against piracy. It assesses the best governance tools in the fight against piracy and upholding of intellectual property rights (IPRs). The instrumentality of IPR laws (treaties) in tackling piracy through good governance mechanisms is also examined. Findings demonstrate that: (1) while all governance (...) tools under consideration significantly decrease the incidence of piracy, corruption-control is the most effective weapon; (2) but for voice and accountability, political stability and democracy, IPR laws (treaties) are instrumental in tackling piracy through government quality dynamics of rule of law, regulation quality, government effectiveness, corruption-control, and press freedom. Hence, the need for a policy approach most conducive to expanding development is to implement an integrated system of both IPRs and corollary good governance policies. Moreover, our findings support the relevance of good governance measures in developing countries wishing to complement their emerging IPR regimes. (shrink)

Assunto pouco estudado na obra de Espinosa, o trabalho ocupa centralidade em seu pensamento acerca do direito comum. Através do exame das ocorrências do trabalho nos dois tratados políticos, bem como da observância da correta tradução de _ opera mutua _, procura-se jogar nova luz sobre a história em Espinosa, em particular sobre a gênese do direito comum e sobre as ideias de justiça e injustiça nesse autor.

The present contribution offers an overview of the main problems concerning the representation of the planets in the pre-Islamic Iranian world, the origin of their denominations, their astral roles and the reasons behind their demonization in the Zoroastrian and Manichaean frameworks. This is a preliminary attempt to resume the planetary iconography and iconology in western and eastern Iranian sources, involving also external visual data, such as those coming from Dunhuang and the Chinese world. The article offers an intellectual journey into (...) a net of mutual cultural and spiritual relations, focusing on the image of the heaven (and of its celestial beings), thereby proposing a new synthesis and highlighting a number of intercultural contaminations.

Este artículo presenta una alternativa a la dicotomía entre razones motivacionales y razones normativas. En Practical Reality, Dancy mantiene que ambas razones se identifican con estados externos al agente--"tesis de la identidad" --. Hay dos argumentos en PR a favor de la TI: El primero se basa en una interpretación externista del significado de "tener una razón". El segundo presenta una vía indirecta, defendiendo que las adscripciones de razones según estados psicológicos internos no son casos centrales en las explicaciones normativas. (...) Estas dos críticas ignorarían una fuerte intuición normativa: el "acceso epistémico". Si ésta es persuasiva, los estados internos no pueden ser eliminables. /// This paper presents an alternative account to the dichotomy between normative and motivating reasons. In Practical Reality, Dancy argues that both types of reasons should be identified with external states of the agent--"identity thesis". There are two arguments in PR for the IT: one is based on an externalist interpretation of expressions like "A has a reason to x". The other is an indirect argument that claims that the ascription of reasons grounded on internal states cannot be central instances in normative explanations. Both arguments ignore a strong intuition: the "epistemic access". If this is a persuasive intuition, internal psychological states cannot be eliminated. (shrink)
