Este texto se propone interpretar la mencionada obra del comediante ateniense a la luz de la múltiple relación entre guerra – eros – paz. La hipótesis que queremos sostener indica que para Aristófanes el hombre se encuentra en un curioso estado paradójico respecto de la guerra, puesto que no puede vivir sin deseo, pero es el deseo el que también conduce a la guerra.

The discovery of transgenes in maize landraces in Mexico, a center of diversity for this crop, raises questions about the potential impact of transgene diffusion on maize diversity. The concept of diversity and farmers’ role in maintaining diversity is quite complex. Farmers’ behavior is expected to have a significant influence on causing transgenes to diffuse, to be expressed differently, and to accumulate within landraces. Farmers’ or consumers’ perceptions that transgenes are “contaminants” and that landraces containing transgenes are “contaminated” could cause (...) these landraces to be rejected and trigger a direct loss of diversity.

Emotions are complex reactions that allow individuals to cope with significant positive and negative events. Research on emotion was pioneered by Darwin’s (1871) work on emotional expressions in humans and animals. But Darwin was concerned mainly with facial and bodily expressions of significance for humans, citing mainly examples from mammals (e.g., apes, dogs, and cats). In birds, emotional expressions are less evident for a human observer, so a different approach is needed. Understanding avian emotions will provide key evolutionary information on (...) the evolution of related behaviors and brain circuitry. Birds and mammals are thought to have evolved from different groups of Mesozoic reptiles, theropod dinosaurs and therapsids, respectively, and therefore their common ancestor is likely to be a basal reptile living about 300 million years ago, during the Carboniferous or Permian. Yet, birds and mammals exhibit extensive convergence in terms of relative brain size, high levels of activity, sleep/wakefulness cycles, endothermy, and social behavior, among others. This article focuses on two basic emotions with negative valence: fear and frustration. Fear is related to the anticipation of dangerous or threatening stimuli (e.g., predators or aggressive conspecifics). Frustration is related to unexpected reward omissions or devaluations (e.g., loss of food or sexual resources). These results have implications for an understanding of the conditions that promote fear and frustration, and for the evolution of supporting brain circuitry. (shrink)

La periode universitaire du Moyen Age se caracterise par un veritable renouveau des formes de production de la pensee: nouvelles sources, nouvelle organisation du savoir, nouvelles theories de l'exegese mais egalement nouvelles pratiques interpretatives. L'ambition de ce livre est double: mettre au jour de maniere unitaire la pratique hermeneutique de l'ensemble de l'oeuvre de Thomas d'Aquin, et proposer par ce biais une methodologie pour optimiser l'etude de cette pratique chez d'autres auteurs de la meme epoque. A cet effet, l'ouvrage propose (...) une analyse systematique de la locution intentio auctoris a partir d'un corpus de pres de sept cent unites textuelles. La portee interpretative de ce syntagme est ici a la fois definie et mise a l'epreuve en vue d'en faire un veritable outil pour les etudes hermeneutiques. L'esquisse lexicale de cette locution, le decodage des criteres de lecture mis en place par Thomas d'Aquin et la determination du caractere juste d'un texte seront les etapes cle de ce parcours.

Jose Marti contributed greatly to Cuba's struggle for independence from Spain with words as well as revolutionary action. Although he died before the formation of an independent republic, he has since been hailed as a heroic martyr inspiring Cuban republican traditions.

There is a common pattern for researchers to study one particular new religion, write a monograph or article on that specific group, and then begin the cycle all over again with a different group. This approach causes one to remember such groups as relatively stable organizations, fixed in memory at a specific stage of development, rather than as dynamic, evolving groups. In the present article, we will examine new data on contemporary Pagans that takes a quasi-longitudinal approach to survey data. (...) Though our focus will be limited, the result will nevertheless be a partial statistical picture of Paganism as a changing, evolving movement, rather than a static statistical snapshot. (shrink)

In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input set is fully accepted, and symmetric change, where both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of postulates and we present different constructions: kernel changes and partial meet changes.

Social and cultural contexts influence power dynamics and shape gender perceptions, roles, and decisions regarding the management of agrobiodiversity for dealing with and adapting to climate change. Based on a feminist political ecology framework and a mixed method approach, this research performs an empirical analysis of two case studies in the northern of India, one in the Himalayan Mountains and another in the Indian-Gangetic plains. It explores context-specific influence of gender roles and responsibilities on on-farm agrobiodiversity management gendered expertise and (...) knowledge related to agrobiodiversity and gendered preferences for practices and institutional arrangements for agrobiodiversity conservation linked to adaptation to climate change. In the Himalayan mountains women actively participate in crop and seed management decisions and tasks, and maintain informal institutions for seed and services exchanges in the case of crisis, which simultaneously favours high levels of agrobiodiversity and enhances women’s social status. By contrast, in the Indio-Gangetic plains, where women from better-off households are socially secluded and women from poorer households work mainly as labourer to respond to high out-migration of men, they exercise less public control over agrobiodiversity, with their role being mainly invisible at the homestead and related to post-production tasks. We finally discuss as improved understanding of the links between gendered spaces, crops, tasks, social status, and agrobiodiversity management can facilitate the design of gender-sensitive policy interventions for conservation and adaptation to climate change.

The deformation and wear events that underlie microwear and macrowear signals commonly used for dietary reconstruction in fossil animals can be replicated and quantified by controlled laboratory tests on extracted tooth specimens in conjunction with fundamental micromechanics analysis. Key variables governing wear relations include angularity, stiffness (modulus), and size of the contacting particle, along with material properties of enamel. Both axial and sliding contacts can result in the removal of tooth enamel. The degree of removal, characterized by a “wear coefficient,” (...) varies strongly with particle content at the occlusal interface. Conditions leading to a transition from mild to severe wear are discussed. Measurements of wear traces can provide information about contact force and particle shape. The potential utility of the micromechanics methodology as an adjunct for investigating tooth durability and reconstructing diet is explored. (shrink)

War and Border Crossings brings together renowned scholars to address some of the most pressing problems in public policy, international affairs, and the intercultural issues of our day. Contributors from widely varying disciplines discuss cross-cultural ethical issues and international topics ranging from American international policy and the invasion and occupation of Iraq to domestic topics such as immigration, the war on drugs, cross-cultural bioethics and ethical issues involving American Indian tribes. The culture clashes discussed in these essays raise serious questions (...) about what principles ought to inform the negotiating of conflicts in order to achieve, or at least approach, outcomes that are fundamentally just, fair, responsible, and ethical.

This paper defends the deflationary character of two recent views regarding scientific representation, namely RIG Hughes’ DDI model and the inferential conception. It is first argued that these views’ deflationism is akin to the homonymous position in discussions regarding the nature of truth. There, we are invited to consider the platitudes that the predicate “true” obeys at the level of practice, disregarding any deeper, or more substantive, account of its nature. More generally, for any concept X, a deflationary approach is (...) then defined in opposition to a substantive approach, where a substantive approach to X is an analysis of X in terms of some property P, or relation R, accounting for and explaining the standard use of X. It then becomes possible to characterize a deflationary view of scientific representation in three distinct senses, namely: a “no-theory” view, a “minimalist” view, and a “use-based” view – in line with three standard deflationary responses in the philosophical literature on truth. It is then argued that both the DDI model and the inferential conception may be suitably understood in any of these three different senses. The application of these deflationary ‘hermeneutics’ moreover yields significant improvements on the DDI model, which bring it closer to the inferential conception. It is finally argued that what these approaches have in common – the key to any deflationary account of scientific representation – is the denial that scientific representation may be ultimately reduced to any substantive explanatory property of sources, or targets, or their relations.

Rapid individual cognitive phenotyping holds the potential to revolutionize domains as wide‐ranging as personalized learning, employment practices, and precision psychiatry. Going beyond limitations imposed by traditional lab‐based experiments, new efforts have been underway toward greater ecological validity and participant diversity to capture the full range of individual differences in cognitive abilities and behaviors across the general population. Building on this, we developed Skill Lab, a novel game‐based tool that simultaneously assesses a broad suite of cognitive abilities while providing an engaging (...) narrative. Skill Lab consists of six mini‐games as well as 14 established cognitive ability tasks. Using a popular citizen science platform (N = 10,725), we conducted a comprehensive validation in the wild of a game‐based cognitive assessment suite. Based on the game and validation task data, we constructed reliable models to simultaneously predict eight cognitive abilities based on the users’ in‐game behavior. Follow‐up validation tests revealed that the models can discriminate nuances contained within each separate cognitive ability as well as capture a shared main factor of generalized cognitive ability. Our game‐based measures are five times faster to complete than the equivalent task‐based measures and replicate previous findings on the decline of certain cognitive abilities with age in our large cross‐sectional population sample (N = 6369). Taken together, our results demonstrate the feasibility of rapid in‐the‐wild systematic assessment of cognitive abilities as a promising first step toward population‐scale benchmarking and individualized mental health diagnostics.
