Combines text with colorful photographs to chronicle the species of animals and plants that are biological relics of a bygone era.

This lavishly illustrated book highlights the conservation importance of congregatory animals species--those which gather in vast groups. It also focuses on the irreplaceability of the congregation sites which are able to support such large gatherings of animals, fish, or birds.

Reflexión sobre el desafío al que nos enfrentamos los docentes si deseamos integrar la inteligencia artificial (IA) en la educación, sin perder de vista los valores humanos y la esencia de la enseñanza. La importancia de encontrar un equilibrio entre la tradición y la innovación, con el objetivo de apoyarnos en la tecnología como una herramienta para enriquecer la interacción humana en el aula. La clave está en aprovechar el potencial de la IA para reforzar la experiencia educativa, sin perder (...) de vista el valor insustituible del vínculo humano en el proceso de aprendizaje. (shrink)

The first urgent question for any scholar willing to study the Open Source (OS) movement has been clearly put by Glass (1999, 104): I don’t know who these crazy people are who want to write, read and even revise all that code without being paid anything for it at all. A growing body of economic literature has been addressing the motivations at the basis of the participation in the OS movement since when the new paradigm has become successful and triggered (...) the entrance on the market of firms offering Open Source based products and services (Open Source firms). However, most of the empirical analyses focus on individual developers and neglect companies that adopt Open Source business models. This paper contributes to the literature by providing empirical evidence on the incentives of the firms that engage in OS activities. Findings on firms’ motivations are compared. (shrink)

A peça trágica, Medeia, é uma das maiores criações de Sêneca. É notável que Medeia tivesse empreendido uma luta interna para manter-se fiel ao seu passado de crimes, pois pretendeu exacerbar seu lado criminoso e, por fim, acabou travando uma batalha com sua própria consciência. No decorrer da peça, invocou até mesmo o universo, solicitando vingança à sua dor; entretanto, ela é mãe, revestida, internamente, de um “medo feminino”. Pretende-se apresentar, neste estudo, de que forma Medeia empreende tal luta interna (...) para arrancar do peito esse sentimento e desvencilhar-se do medo feminino a ponto de tornar-se “inumana” e matar os próprios filhos.

This study explores the intra-organizational antecedents of sustainable governance by examining the impact of female presence at the corporate apex. Drawing upon the upper echelon theory, we investigate whether women in top positions influence sustainable governance practices. Our research focuses on a sample of companies operating within two distinct market economies: liberal market economies (LMEs) and coordinated market economies (CMEs). The United States, represented by the S&P100, and the United Kingdom, represented by the FTSE100, serve as examples of LMEs. Conversely, (...) Germany (DAX30), France (CAC40), Spain (IBEX35), and Switzerland (SMI) are illustrative of CMEs. Analyzing archival data spanning from 2010 to 2019, we confirm that the presence of a critical mass of women on the board of directors significantly increases the likelihood of establishing a sustainability committee within organizations. This relationship holds true across both LMEs and CMEs, highlighting the universal importance of gender diversity in driving sustainable governance initiatives. Interestingly, we observe that the impact of women with structural power on sustainability committee formation is specific to LMEs, suggesting the context-dependent nature of female leadership in sustainable governance.

El presente trabajo estudió la relación entre el derecho a la identidad en toda su esfera y la prohibición del anonimato de donantes de gametos en la aplicación de técnicas de reproducción humana asistida. La metodología se desarrolló desde un enfoque cualitativo, se utilizaron los métodos inductivo-deductivo, dogmático, histórico-lógico, comparativo y analítico-sintético, la técnica aplicada fue la revisión bibliográfica de ley, doctrina y jurisprudencia. Como conclusión se estableció la vulneración de derechos al inexistir una ley que regule el anonimato de (...) donantes. Adicionalmente se sugiere que, el Estado ecuatoriano cuente con una normativa completa, rígida y sobre todo garantista de los derechos de los intervinientes en las técnicas de reproducción humana asistida, de manera especial a las personas nacidas a través de gametos donados.

Stanovich & West continue a history of norm-setting that began with deference to reasonable people's opinions, followed by adherence to probability theorems. They return to deference to reasonable people, with aptitude test performance substituting for reasonableness. This allows them to select independently among competing theories, but defines reasoning circularly in terms of aptitude, while aptitude is measured using reasoning.

A brief theoretical review of the current state of the art of embodiment research in clinical psychology has been expounded in order to highlight the key role that embodied conceptualization has on the understanding and explanation of several mental disorders, such as eating disorders, schizophrenia and depression. Evidence has suggested that mental disorders may be explained as disturbances of embodiment, from the disembodiment to the hyperembodiment. In order to understand how some clinical conditions are affected by cultural models, we propose (...) and define a new framework called Exbodiment, complementary to the Embodiment approach to cognition. Mental disorder is strictly related to the subject-culture interaction that may be explained as a two way process in which embodiment and exbodiment are complementary points of view. In this perspective, embodiment may be seen as the “top-down” process, while exbodiment the “bottom-up” one. The introduction of exbodiment conceptualization highlights how subject is both receiver and interpreter of social influence. Subject is the target of a cultural pressure and, at the same time, enacts its own embodied culture in world. Exbodiment conceptualization may help clinicians to better understand and explain the role of culture in the onset and maintenance of mental disorders. (shrink)

From the beginning of history sounds have played a fundamentally important role in humanity’s development as ways of expression and of communication. However in contemporary western society, and indeed globally, we are experiencing an excess of speech and a relentless encouragement to expression. Such excess indicates a misunderstanding about what expression and dialogue should be. This condition encourages us to think about silence, solitude and contemplation and the role they might play in restoring the realm of personal understanding of the (...) Self and of one’s authentic experience of the Other. The purpose of this article is to explore the potency of a silence that arises from our participation in the world. We present first some ideas about silence as a human phenomenon. This is followed by an examination of silence and language, an investigation of silence in dialogue, and of its educational implications. The article concludes by emphasising the value of silence as potency in itself, assisting in recovering the expressive powers of language. We argue that it is important to understand the positive status of silence in order to recognise and avoid repressive speech and to introduce its potential for reflective learning. (shrink)

Lo que me propongo exponer es una comparación de sistemas, el dela dirección del tiempo con el sistema de la causalidad, donde me parecemás básico o plausible en una teoría metafísica elegir la direccióndel tiempo con un sentido de antes a después, porque de esta maneranos permite dar una explicación coherente y lógica de la realidad queestamos percibiendo.

Corporeality is a subject strongly present in educational discussion nowadays. The purpose of this paper is to present an outline of issues we may address from the philosophy of sport that could foster a fruitful dialogue with the philosophy of education. It is understood that the philosophy of education can benefit from reflections on corporeality and human movement, namely from sports and games. Initially, the article introduces the philosophy of sport as a field of study that addresses reflections on human (...) movement from sports and games. They highlight elements that are not specific to such practices and foster reflexions on different areas. Afterwards, it explores the experience of corporeality and the dialogical dimension of human movement based on Merleau-Ponty's phenomenology. Human movement indicates a unique way of being communicative. Finally, it presents some reflections on playing games as an experience that helps us think about our relationships with others and the environment. From this perspective it is possible to seek some critical features to understand education in the experience of human movement, namely from playing games, such as experience, dialogue, and expressiveness. Thoughts on human movements may reinforce the role corporeality plays in education as a collective experience and the recognition of the body's expressive potential in constructing knowledge.

The development of bacterial resistance to antibiotics is one of the best documented examples of contemporary biological evolution. Variability in the mechanisms of resistance depends on the diversity of genotypes in the huge bacterial populations, and also on the diversity of selective pressures that are produced along the antibiotic concentration gradients formed in the highly compartmentalized human body during therapy. These antibiotic gradients can be conceived as comprising selective compartments, each one of them defined as the concentration able to select (...) a particular genetic variant.In vitroexperimental models confirm that some antibiotic resistant variants are selected only at certain selective concentrations of antibiotics. The correspondence between selective compartments and selectable variants could offer a way of describing more accurately the antibiotic selective landscapes and for taking measures to prevent the development of a major threat to the future of modern medicine.

Los temas que contiene van desde estudios sobre los contextos culturales español e hispanoamericano en los que le tocó vivir a nuestro filósofo, y trabajos sobre los principales temas filosóficos sobre los que centró su abundante producción escrita.

Estuda as origens do pensamento filosófico ocidental sobre Educação, a partir da sociedade grega antiga, de base escravocrata. Destaca as diferentes etapas de formação da concepção grega de Educação ou Paideia e discute seus significados e desdobramentos. Aponta a Paideia como um ideal de educação plena, educar para a vida, como processo de formação humana. Estuda topicamente as etapas da organização da educação e da escola no Brasil. Analisa as políticas sociais e educacionais e explicita as características autoritárias e excludentes (...) da sociedade e, por conseguinte, da escola no Brasil. Afirma suas características adultocêntricas e impositivas e aponta ser necessária uma superação das marcas e dos determinantes de natureza social e política para a construção ou para a emergência de práticas de reconhecimento da Criança e da Infância no Brasil. A prática pedagógica de acolhimento da Criança na escola necessita de superações de natureza filosófica e política dos estigmas das formações pedagógicas dominantes. (shrink)

Este artículo propone una revisión crítica del concepto de desigualdad tomando como base de análisis la política europea de lucha contra la pobreza y la exclusión y se pregunta sobre las formas en las que se construye y tiene en cuenta el concepto de interseccionalidad en las narrativas sobre las que se ha ido desarrollando durante los últimos 20 años. La hipótesis de la que se parte es que estas políticas se han dirigido tradicionalmente a grupos específicos desde un enfoque (...) unitario; es decir, a partir de una categoría única, considerada la más relevante o explicativa políticamente en situaciones particulares de desventaja social. De esta manera, la política europea de lucha contra la pobreza y la exclusión se ha institucionalizado sin tener en cuenta el carácter complejo de las desigualdades. (shrink)

El concubinato es una relación con consecuencias legales discutidas y reguladas por todas las escuelas jurídicas islámicas. Las relaciones entre un hombre y su concubina están limitadas por distintas normas de carácter jurídico-religioso, que tienen que ver con diferentes factores: tabúes sexuales y familiares, el estatus de esclava de la concubina, las obligaciones del hombre respecto a los individuos que hay bajo su guarda, etc. El objetivo de este artículo es estudiar cuáles son los límites del concubinato según los establece (...) la doctrina legal mālikí, prestando especial atención a los casos en que las relaciones de matrimonio o concubinato se asemejan o difuminan. El estudio se lleva a cabo a través del tratado de derecho comparado de Ibn Rušd (Averroes), Bidāyat al-muŷtahid. (shrink)

Socio-economic status and mathematical performance seem to be risk factors of mathematics anxiety in both children and adults. However, there is little evidence about how exactly these three constructs are related, especially during early stages of mathematical learning. In the present study, we assessed longitudinal performance in symbolic and non-symbolic basic numerical skills in pre-school and second grade students, as well as MA in second grade students. Participants were 451 children from 12 schools in Chile, which differed in school vulnerability (...) index, an indicator of SES. We tested an explanatory model of MA that included SES and longitudinal performance in basic numerical skills as predictors. The results showed a direct effect of SES on MA and a mediating effect of performance in symbolic and non-symbolic comparison tasks in pre-school. However, in second grade, only performance in symbolic comparison significantly mediated the SES-MA relationship. These findings suggest that performance in non-symbolic comparison plays an important role in explaining MA at initial stages, but that its influence is no longer significant by the time children reach formal instruction in second grade. By contrast, as children’s formal educational experience in mathematics increases, MA becomes linked primarily to symbolic numerical tasks. In sum, SES affects MA and this is due in part to the effect of SES on the development of numerical learning in pre-school, which in turn has an impact on subsequent, more complex learning, ultimately leading to differences in MA. We discuss the implications of these findings for preventing and acting upon the emergence of MA. (shrink)
