Nowadays hypermedia constitutes, with its singular characteristics, a new language whose structure seems to be complex because it includes features such as multiple simultaneous paths, multiplicity of voices, the simultaneous manifestation of ordinary and scholarly languages and the mixture of means, genres and verbal, visual and aural languages. However, behind its complexity, hypermedia can reveal simple structures of order. Comprehending its nature, we can better construct using its language. This has great potential for creating narratives understood as universal manifestations of (...) human discourse through which people share their comprehension of the world. Using a parallel between the narrative structure of hypermedia and that found by the anthropologist Claude Lvi-Strauss in South-American indigenous mythical narratives, I looked for an alternative perspective for the comprehension and manipulation of the hypermedia logic structure and the resources it mobilizes to form a coherent whole, such as the temporality and spatiality of narratives, symbology and metaphors and its own alternative means of producing meaning.

The question concerning the meaning of life is important, but it immediately confronts the present authors with insurmountable obstacles from a philosophical standpoint, as it would require us to define not only what we hold to be life, but what we hold to be meaning in addition, requiring us to do both in a properly researched context. We unconditionally surrender to that challenge. Instead, we offer a vernacular, armchair approach to life’s origin and meaning, with some layman’s thoughts on the (...) meaning of origins as viewed from the biologist’s standpoint. One can observe that biologists generally approach the concept of biological meaning in the context of evolution. This is the basis for the broad resonance behind Dobzhansky’s appraisal that “Nothing in biology makes sense except in the light of evolution”. Biologists try to understand living things in the historical context of how they arose, without giving much thought to the definition of what life or living things are, which for a biologist is usually not an interesting question in the practical context of daily dealings with organisms. Do humans generally understand life’s meaning in the context of history? If we consider the problem of life’s origin, the question of what constitutes a living thing becomes somewhat more acute for the biologist, though not more answerable, because it is inescapable that there was a time when there were no organisms on Earth, followed by a time when there were, the latter time having persisted in continuity to the present. This raises the question of where, in that transition, chemicals on Earth became alive, requiring, in turn, a set of premises for how life arose in order to conceptualize the problem in relation to organisms we know today, including ourselves, which brings us to the point of this paper: In the same way that cultural narratives for origins always start with a setting, scientific narratives for origins also always start with a setting, a place on Earth or elsewhere where we can imagine what happened for the sake of structuring both the problem and the narrative for its solution. This raises the question of whether scientific origins settings convey meaning to humans in that they suggest to us from what kind of place and what kinds of chemicals we are descended, that is, to which inanimate things we are most closely related.

Commitment has been perceived as a strategic topic in organizations due to its positive effect on retaining talent, increasing performance, or boosting employees’ innovative behavior. However there are many focis of commitment in the workplace, which has represented a challenge to human resources management, who need implement measures to improve the employee’s commitment. Recent research has suggested a need to conduct studies about commitment, namely antecedents and the relationship between different focis, to understand the dynamic and directionality between them. Hence, (...) the purpose of this work is to analyze how employees’ emotional awareness relates with two focis of commitment, also assessing the mediating role of affective commitment to the leader. The study uses structural equation modeling and Lisrel to test the hypotheses considering the multidimensionality of organizational commitment, employees emotional awareness, and the affective commitment to the leader, under the scope of Social Exchange Theory. The Mackinon’s Z Test was used to assess the mediation role of affective commitment to the leader. The sample is composed for 403 employees from two multinational companies. The results provide empirical evidence about the mediating role of affective commitment to the leader in the relationship between employees’ emotional awareness and organizational commitment, and the employees’ emotional awareness as an antecedent of commitment. The implications for theory and practice are discussed. (shrink)

The analysis of penalty kick has played an important role in performance analysis. The study aims are to get formal feedback on the relevance of variables for penalty kick analysis, to design and validate an observational system; and to assess experts’ opinion on the optimum video footage in penalty kick analysis. A structured development process was adopted for content validity, reliability and agreement on video usage. All observational variables included in OSPAF showed Aiken’s V values above the cut-off. Cohen’s Kappa (...) resulted in mean intra- and inter-rater reliability values of 0.90 and 0.86, respectively. It is recommended to combine at least three different viewing angles with standardization of video quality. Changing the viewing angles may influence the observer perception. The aerial and pitch-level viewing angle behind the penalty taker and pitch-level viewing angle behind the goalkeeper were indicated as most appropriate for observational analysis. The OSPAF met all requirements of instrument validation. It may be recommended as basis of future observational systems on penalty kicks. (shrink)

O artigo busca examinar, no pensamento de Martín de Azpilcueta (1492- 1586), a questão da justificação moral da prática comercial. Na intenção de alcançar este objetivo, buscar-se-á explorar a compreensão da moralidade envolvendo a atividade comercial em pensadores anteriores a Azpilcueta que trataram do tema e, que de certa forma, o influenciaram na abordagem da questão. Nessa perspectiva, será destacada a discussão trazida por Tomás de Aquino (1225-1274) e João Duns Scotus (1265-1308). Assim, se investigará como o legado destes dois (...) grandes filósofos medievais influenciaram a compreensão de Azpilcueta sobre o tema da defesa da legitimidade moral da prática comercial, discussão essa que o pensador trata em sua obra Commentaria in septem distinctiones de poenitentia.

Neste artigo pretender-se-á estabelecer as bases sobre as quais Martín de Azpilcueta demonstra sua fundamentação da autoridade política no intuito de refletir sobre como este pensador articula sua argumentação no intuito de apresentar o povo como detentor originário, por direito natural, do poder civil. Para que este objetivo possa ser alcançado buscar-se-á apresentar como o autor relaciona e distingue o poder eclesiástico do poder laico ou civil. Em seguida demonstrar-se-á como o pensador espanhol estabelece sua fundamentação da autoridade civil popular (...) ao defender que o poder civil se legitima por ter sua origem em Deus, por ser de ordem natural e ser dado de forma imediata à comunidade dos mortais. A partir disso é possível considerar que a autoridade política laica, conforme o pensamento de Martín de Azpilcueta, tem o povo como seu legítimo depositário e que disso decorre a igualdade original primária de todos os homens na vida pública. Para que se possa realizar o objetivo apresentado neste trabalho estudar-se-á, de maneira específica, a Notabile tertium presente na obra Martín de Azpilcueta chamada Relectio C. Novit de Iudiciis publicada pela primeira vez em Coimbra no ano de 1548. (shrink)

Assinalando o quinto centenário da morte do pintor Sandro Botticelli (1445-1510), homenageia-se aqui a obra deste artista destacado do Renascimento através da relação entre dois dos seus mais importantes quadros e textos de dois autores italianos: Nastagio degli Onesti e Nascimento de Vénus contêm duas representações da mulher, coincidindo tanto no comportamento que dela espera a sociedade renascentista, como nos modelos medievais de Giovanni Boccaccio (1313-1375) e de Francesco Petrarca (1304-1374).O conjunto pictórico Nastagio degli Onesti, baseado em “A terrível (...) visão” (um dos cem contos da obra Decameron, de Boccaccio), pode ser entendido como um veículo de propaganda doutrinária ao serviço de uma ideologia feudal, que propõe a submissão do “objecto” feminino ao sujeito masculino, ao matrimónio e aos mais elevados interesses oligárquicos.O Nascimento de Vénus é, muito provavelmente, o quadro mais famoso de Botticelli. Pintado no auge da sua carreira, procura transpor o cânone estético da Vénus pagã da Antiguidade para a Laura cristã de Petrarca: a mulher, como símbolo da baixa paixão carnal, metamorfoseia-se no mais elevado amor espiritual. Com efeito, a Vénus botticelliana tem a beleza da Laura petrarquista, seguindo ainda o cânone provençal para destacar os seus predicados físicos. (shrink)

The discussion of collective agency involves the reduction problem of the concept of a collective. Individualism and Cartesian internalism have long restricted orthodox theories and made them face the tension between an irreducible concept of a collective and ontological reductionism. Heterodox theories as functionalism and interpretationism reinterpret the concept of agency and accept it as realized on the level of a collective. In order to adequately explain social phenomena that have relations as their essence, in this paper we propose a (...) relational, holistic account of collective agency and argue that functionalism and interpretationism can be integrated into such an account.

Causal contextualism holds that sentences of the form ‘c causes e’ have context-sensitive truth-conditions. We consider four arguments invoked by Jonathan Schaffer in favor of this view. First, he argues that his brand of contextualism helps solve puzzles about transitivity. Second, he contends that how one describes the relata of the causal relation sometimes affects the truth of one’s claim. Third, Schaffer invokes the phenomenon of contrastive focus to conclude that causal statements implicitly designate salient alternatives to the cause and (...) effect. Fourth, he claims that the appropriateness of a causal statement depends on what is contextually taken for granted or made salient. We show that causal invariantism can explain these linguistic data at least as well as contextualism. We then argue that pace Schaffer, some causal sentences are always correct and can never be plausibly denied, regardless of the context. (shrink)

The International Bill of Human Rights (IBHR) enjoys universal acclaim as the source of the best standards and definition of human rights. This paper argues that the IBHR is inspired by liberalism and harbours ambiguities that open the door to a neoliberal seizure of the rights agenda; and that this effectively destabilises the focus on the IBHR on socio-economic and community rights, and therefore its stated ideal of the equal value of all human rights. I argue that Kwame Gyekye's moderate (...) communitarian political philosophy affords a viable philosophical basis for justification of a more balanced conception of human rights than the theoretical basis of the IBHR does.

Liberal neutrality is assumed to pertain to rival conceptions of the good. The nature of the rivalry between conceptions of the good is pivotal to the coherence, scope and realisation of liberal neutrality. Yet, liberal theorists have said very little about rivalry. This paper attempts to fill this gap by reviewing three conceptions of rivalry: incompatibility rivalry, intra-domain rivalry and state power rivalry. I argue that state power rivalry is the morally relevant conception of rivalry, and that it has significant (...) implications for the scope and realisation of liberal neutrality. I conclude that in the light of state power rivalry, the only feasible liberal neutral state is a very minimal one. (shrink)

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist supposes that some such episodes have as constituents mind-independent objects. In turn, the disjunctivist claims that in a case of (...) veridical perception like this very kind of experience that you now have, the experiential episode you enjoy is of a kind which could not be occurring were you having an hallucination. The common strategy of arguments from hallucination set out to show that certain things are true of hallucinations, and hence must be true of perceptions. For example, it is argued that hallucinations must have non-physical objects of awareness, or that such states are not relations to anything at all, but are at best seeming relations to objects. In insisting that veridical perceptual experience is of a distinct kind from hallucination, the disjunctivist denies that any of these conceptions of hallucination challenges our conception of veridical perceptions as relations to mind-independent objects. More specifically, I assume that the disjunctivist advocates naïve realism because they think that this position best articulates how sensory experience seems to us to be just through reflection. If the disjunctivist is correct in this contention, then anyone who accepts the conclusion of the argument from hallucination must also accept that the nature of sensory experience is other than it seems to us to be. In turn, one may complain that any such error theory is liable to lead to sceptical consequences. A Humean scepticism about the senses launches a challenge about our knowledge of the world through questioning the conception we have of what sense experience is, and how it can provide knowledge of the world.

This article explores the usefulness of Latin American philosopher Enrique Dussel's work for film-philosophy, as the field increasingly engages with a world of cinemas. The piece concludes with an analysis of two films with an ecological focus, Trolljegeren/Troll Hunter (2010) and The Hunter (2011). They are indicative of a much broader emerging trend in ecocinema that explores the interaction between humanity and the environment in relation to world history, and which does so by staging encounters between people and those ‘nonhuman’ (...) aspects of the Earth excluded by coloniality/modernity (e.g. animals, animal-spirits, mythological creatures, shaman, the very Earth itself). The interdisciplinary concerns of this work place it at the intersection of the latest research into a world of cinemas (in particular the various moves to understand films beyond the national paradigm now increasingly labelled the ‘transnational turn’; alongside growing concerns with how cinema helps us engage with ecology); and the need to broaden our philosophical grasp of the world. This latter point requires engagement with thinkers from beyond the Eurocentric canon of Western thought that currently dominates philosophy, and equally shapes film-philosophy. Dussel's philosophy is shown to provide a perspective capable of illuminating the intertwined nature of human and planetary history evident in these films, in a manner that is extremely pertinent to our global situation. Thus it is shown to be more useful than approaches to similar groupings of films which draw on, for example, speculative realism, when it comes to providing a cine-ethics appropriate to the Anthropocene.

This paper argues that the allure of conspiracy theories lies in their evolutionary origins, specifically in our capacity to communicate unrepresented threats. Drawing on threat-detection psychology and error management theory, it posits that these theories serve as adaptive responses to perceived threats and social coalition-building, rather than as flaws in reasoning.

Article copyright 2002. We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher's view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second (...) factor in the etiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows, but we point out some problems that confront any attempt to say more about the nature of this second factor.

In this paper I argue that medical education must remain attuned to the interests that physicians have in their own self-development despite ongoing calls for ethics education aimed at ensuring physicians maintain focus on the interests of the patient and society. In particular, I argue that medical education should advance criteria defining what counts as an educationally worthwhile activity from the perspective of the medical student understood as a learner. I offer a preliminary account and justification of such criteria, arguing (...) that such criteria warrant a process of ethical formation that better serves the interests of medical students, their patients and society.

The influences large corporations have on the lives of most citizens is huge. In the developed world the relationships between corporations and citizens is generally close, with top corporate managers making decisions that shape the societies which they share with their fellow citizens. Individuals in Western society may be trained to accept the status quo, which allows business leaders significant influence over the allocation of society’s assets, and thereby over societal developments. Formal education systems often encourage the maintenance of the (...) status quo, whereas they could encourage students to challenge it. This paper argues the need to help business students develop an understanding of critical theory, independent thought and self-improvement. The paper employs a case study approach which focuses on the development of one person, its author. He argues that those responsible for education today must encourage their students to think holistically about the consequences of business behaviour on society. If managers view business life through a scientific lens, focused primarily on the maximisation of financial returns, they will continue to encourage unsustainable behaviour, which damages the ecosystems and the social cohesion in society. Managers must learn to approach their business decisions as whole human beings. This will make it more likely they will manage in a sustainable way, and help them find meaning and happiness in their roles. (shrink)

We describe seven challenges that confront the kind of cross-cultural research currently practiced in experimental philosophy, illustrating them in an example in which intuitions about moral responsibility were studied in participants in four different countries. The seven challenge are (1) defining culture, (2) finding representative samples, (3) defining cognition, (4) task variation, (5) ecological validity, (6) interpreting the results, and (7) conducting ethical research. We suggest that these challenges can be overcome or avoided by attending to the ways cognition arises (...) in everyday life, and briefly describe an approach which regards culture not as an independent variable but as the medium of human action and human life, and which regards cognition as situated in time and place.

Resumo O entendimento de Friedrich Nietzsche sobre Friedrich Schiller é bem conhecido e culmina em 1888, na desqualificação que se tem com “Schiller: ou o trompetista moral de Säckingen”. Mas é sabido que suas considerações são contraditórias, mudando com frequência nas diferentes etapas de sua vida produtiva. A monografia de Nicholas Martin marca um ponto de viragem no que diz respeito a este tema, refutando a disseminada compreensão de que somente o jovem Nietzsche teria experimentado admiração por Schiller, depois (...) vindo a assumir distância cada vez maior. A dívida de Nietzsche para com Schiller, segundo Martin, é constante, e manifesta-se sobretudo em sua recepção das cartas estéticas. O que se pretende fazer ver aqui, seguindo a tradição de Wolfgang Riedel, é que o ensaio Sobre a poesia ingênua e sentimental [Über naive und sentimentalische Dichtung] é tão ou mais importante neste contexto sobretudo quando dirigimos nosso enfoque para o contexto da crítica cultural. Várias declarações de Nietzsche, por exemplo, formulada em 1870, “não estou em condições de empregar essa terminologia esplendorosamente schilleriana para o inteiro e mais amplo domínio de toda a arte”, confirmam tal suposição, e uma vez que, no mesmo momento de elaboração de O nascimento da tragédia no espírito da música, ele se propõe a “[…] fortalecer o conceito do ingênuo e do sentimental”, tem-se justificada a intenção de relacionar ambas as obras-chave de ambos os Dichterphilosophen [filósofos poetas] do ponto de vista da crítica cultural.Friedrich Nietzsche's opinion about Friedrich Schiller is well known and culminates in 1888 in the disqualification “Schiller: oder der Moral-Trompeter von Säckingen”, but at the same time it is recognized that his considerations are contradictory and that they change in the different moments of his productive life. Nicholas Martin's study from 1996 marks a caesura in this subject by refuting the widespread view that only the young Nietzsche experienced admiration for Schiller and that there was a growing distance afterwards. Nietzsche's debt to Schiller, according to Martin, is constant and is manifested above all in his reception of the aesthetic letters. We would like to demonstrate in the tradition of Wolfgang Riedel that the essay Über naive und sentimentalische Dichtung is equally or even more important in this context, especially when it is approached from the standpoint of cultural criticism. Several statements by Nietzsche, such as the one formulated in 1870 “Ich bin nicht im Stande, jene herrliche Schillersche Terminologie auf das ganze weiteste Bereich aller Kunst anzuwenden” confirm this assumption, and when, at the very moment when Die Geburt der Tragödie aus dem Geist der Musik was being prepared, Nietzsche proposed that the “[…] Begriff des Naiven und des Sentimentalistischen ist zu steigern”, the attempt to link both key works of the two Dichterphilosophen from the point of view of cultural criticism is justified.

Wie kein anderer Philosoph vor oder nach ihm thematisierte Heidegger die metaphysischen Denkschemata, die der abendländisch-neuzeitlichen Technikentwicklung zugrunde liegen. Auf verständliche Weise rekonstruiert dieses Buch Heideggers radikal metaphysikkritischen Ansatz vor dem Hintergrund seiner frühen und mittleren Schriften. Dabei wird nicht nur deutlich, wie sehr sein spätes Denken der Technik in Kontinuität zu seinem frühen fundamentalontologischen Projekt (und dessen Scheitern) steht, sondern es werden auch die Alternativen zum rechnenden Denken und Handeln in Kunst und Dichtung aufgezeigt.

This article develops an ecological framework for understanding collective action. This is contrasted with approaches familiar from the collective intentionality debate, which treat individuals as fundamental units of collective action. Instead, we turn to social ecological psychology and dynamical systems theory and argue that they provide a promising framework for understanding collectives as the central unit in collective action. However, we submit that these approaches do not yet appreciate enough the relevance of social identities for collective action. To analyze this (...) aspect, we build on key insights from social identity theory and synthesize it with embodied and ecological accounts of perception and action. This results in the proposal of two new types of affordances. For an individual who enacts her "embodied social identity" of being a member of a particular collective, there can be what we call embodied social identity affordances. Moreover, when several individuals dynamically interact with each other against the background of their embodied social identities, this might lead to the emergence of a collective, which we understand as a dynamically constituted and ecologically situated perception-action system consisting of several individuals enacting relevant embodied social identity affordances. Building on previous work in social ecological psychology, we suggest that there can be genuine collective affordances, that is, affordances whose subject is not an individual, but a collective.
