The rich diversity of avian natural history provides exciting possibilities for comparative research aimed at understanding three-dimensional navigation. We propose some hypotheses relating differences in natural history to potential behavioral and neurological adaptations possessed by contrasting bird species. This comparative approach may offer unique insights into some of the important questions raised by Jeffery et al.

In lieu of an abstract, here is a brief excerpt of the content:Saving Honor:The Ideology of Equal Esteem and the Good of Honor, Friendship, and Glory according to St. ThomasDominic Verner O.P.In his book Natural Law and Human Rights, Pierre Manent assesses and critiques a practical ideology that he finds pervasive within the European academy and sees increasingly informing the practical sensibilities of much of the Western world. "Our governing doctrine," as Manent calls it, is chiefly characterized by the (...) primacy of right over law and the rejection of any objective principle by which actions and persons might be judged.1 It is "the plasticity of the human form" itself which demands respect.2 The only non-constructed and thus normative characteristic of equal human nature is the power of being an "individval-conatus," the power to be one's own rule and reason for acting.3 And the only generally recognized purpose of this "individual-conatus" is to satisfy the desire for power, which is the sole universal motive of human action.4 Such an individual can be legitimately ruled and governed only by himself, a claim reflected in the ideal of the autonomous subject and representative government.5 In sum, Manent characterizes this ideology in terms of a thoroughgoing [End Page 335] rejection of any objective rule, "any law of God or of nature," according to which man is defined and judged.6Manent warns that this ideology is opposed to the very wellsprings of action, since an operation is rightly called an action only when it is performed according to some deliberate choice, which requires some rule and reason. If all rules and reasons are entirely self-generated, then there is no principle according to which deliberation might occur. Such a so-called autonomous subject purports to command himself, but in fact he is more patient than agent: the subject is moved by desires and preferences which cannot be weighed according to any discriminatory rule or principle, since the desires and preferences themselves are the only rule the subject acknowledges. Aside from submitting to the movement of the inexplicably strongest preference, the only positive reason for acting that remains is to destroy any vestiges of objective rules or reasons for acting—that is, the law—that might hinder the realization of individual preference: "The acting animal is now the prisoner of the very audacious and ingenious arrangement that he once devised to escape the urgency and to avoid the difficulty of the practical question. Caught in the realm of inaction, he seeks out, in a kind of terminal fever, the last corners of social existence that still escape the laissez-faire idea and where the very idea of the law might suffer its final defeat."7What is a Christian to make of this practical ideology? What natural inclinations does it privilege and how might the goods it seeks be sought rightly? Manent argues that the sole universal motive for action explicitly recognized by this practical ideology is a certain kind of power: the power of self-determination. According to the governing doctrine, this power is the only universal human motive that can be relied upon to construct common life and political order. Manent's response to this ideology is therefore to propose a recovery of a natural law account of the heterogeneity of universal human motivations to include useful, pleasing, and honorable goods. In this article, I will argue that Manent's own account of the ideology he critiques suggests a more fundamental motive driving the ideology, namely, a desire for an unassailable esteem. And since it is a desire for esteem that best explains the attractiveness of the ideology of modern freedom, an alternative vision of practical life will need to address the desire for esteem and articulate its proper bases. In advancing this argument, I will first show that Manent's own analysis highlights the importance of the desire for esteem in motivating the ideology of modern freedom. I will then turn to the anthropology of Thomas [End Page 336] Aquinas to show that the desire for esteem is manifested in the desire for honor and for friendship and is rooted in a fundamental inclination to have certain knowledge of one's...

We investigate which filters onωcan contain towers, that is, a modulo finite descending sequence without any pseudointersection. We prove the following results:Many classical examples of nice tall filters contain no towers.It is consistent that tall analytic P-filters contain towers of arbitrary regular height.It is consistent that all towers generate nonmeager filters, in particular Borel filters do not contain towers.The statement “Every ultrafilter contains towers.” is independent of ZFC.Furthermore, we study many possible logical implications between the existence of towers in filters, (...) inequalities between cardinal invariants of filters $,${\rm{co}}{{\rm{f}}^{\rm{*}}}\left$,${\rm{no}}{{\rm{n}}^{\rm{*}}}\left$, and${\rm{co}}{{\rm{v}}^{\rm{*}}}\left$), and the existence of Luzin type families, that is, if${\cal F}$is a filter then${\cal X} \subseteq {[\omega ]^\omega }$is an${\cal F}$-Luzin family if$\left\{ {X \in {\cal X}:|X \setminus F| = \omega } \right\}$is countable for every$F \in {\cal F}$.

We show that MAκ implies that each collection of Pc-points of size at most κ which has a Pc-point as an RK upper bound also has a Pc-point as an RK lower bound.

The purpose of this paper is to take a critical look at some of the assumptions and theories found in economics and management and discuss their implications for the practices found in the management of business and in public management. Two sets of assumptions are of interest here. First and foremost, the assumption that economic agents are only actuated by self-interest, accompanied by assumptions about the motivating effect of pecuniary incentives and assumptions about the regulation of behaviour through rules, controls (...) and sanctions; secondly, assumptions about “scientificness” and objectivity, accompanied by demands for mathematical formalism, clear goals, quantifiable models and measurements. The assertion is that unrealistic assumptions of economics have become taken for granted and tacitly included into theories and models of management. Guiding management to behave in a fashion that apparently makes these assumptions become “true”. Cases and illustrative examples are used to show how this influences the practice of decision makers and managers. (shrink)

‘Isn’t it clear that a man must have the right to warn the majority, to argue with the majority, to fight with the majority if he believes he holds the truth? Before many can know something, one must know it!’ The words are Dr Stockman’s of An Enemy of the People1 and in a competitive market building upon a Smithian self-interest there might seem to be no room for people like him. Whatever the personal attitudes of the owners, managers and (...) employees, they would feel forced to behave in business like all of their competitors. Such is the logic of the basic driving forces in Western societies. It is a logic that necessitates lean and mean production, the substitution of labour with capital, relocation of production to places with low labour costs — also known as social dumping — or to places with less stringent environmental demands and/or less costly safety regulations. The traditional way to prevent this happening has been to use state intervention and regulation to curb the worst cases. But today many of the traditional harnesses on an unbridled market economy have been removed, such as controls on capital movements, trade across borders or regulation of sectors like transport, telecommunication, energy, utilities and so on. With this in mind we may ask whether there exists an alternative to state intervention that would contain or change the direction of the logic from within the logic itself. In other words, is it possible for a single or a few entrepreneurs to change the logic in such a way that external regulation is avoided or reduced, while finding answers to the problems and concerns caused by that logic? Of course there is a risk that these answers may consist of just a kind of exploitative riding of the waves of concerns and offering strange, Potemkin-like answers to for instance the clamour for environmental responsibility. Responsible entrepreneurship is something else, though. It consists in understanding genuine concerns and using one’s special knowledge in a certain field, to experiment and develop constantly improving answers to these concerns, giving a concrete form to emerging values, and raising the expectations of all those having these concerns.

In this article, I defend Thomistic eudaimonism against John Hare's Kantian charge of unacceptable self-regard, and argue that Hare's own Scotistic-Kantian double-source theory of motivation introduces a problematic conception of beatitude. Hare argues that the beatitude which motivates the will in Thomistic eudaimonism is a self-indexed good, which cannot motivate truly altruistic action. Hare fails to recognize that the beatitude that ultimately motivates the human will according to Thomas can be an ‘ourself-indexed’ rather than merely a ‘myself-indexed’ good, as the (...) love of friendship brings other selves into the will's self-intention, facilitating a truly intersubjective and communal beatitude. Rejecting beatitude as the sole motivation of the will, Hare proposes a Scotistic double-source theory of motivation where the beatitude of another and the agent's own beatitude can never be loved with one and the same affection of the will, rendering beatitude unacceptably exclusive and proprietary. By making this argument, I hope to show that contemporary debates concerning moral motivation should carefully consider whether they can account for the intersubjective beatitude that bolsters human solidarity and forms the object of hope given by Christ who wills that his joy may be in us.

An integral method of keeping a non-conforming community functioning is the construction and up keep of networks, as this web of connections provided security and protection with other non-conformists against the persecuting authorities. The non-conforming Catholic community of Elizabethan England established various networks within England and abroad. This article is based on research that examines the network of Catholics in the Elizabethan Midlands in order to understand both its effectiveness and the relationship of the local and extended Catholic community with (...) one another. The construction, function and result of these networks will be surveyed over several categories of networks, such as local, underground, clerical and exile. Members of the Midland Catholic community travelled to others areas of the British Isles and Europe to gather spiritual and material support for their faith, sent their children abroad for religious education, and resettled abroad creating in this wake a larger and complex international network. The main objective of this exercise is to show the dynamic and function of the network, and understand the impact it had at the local level for Midland Catholics. (shrink)

In this short paper, we describe another class of forcing notions which preserve measurability of a large cardinal $\kappa$ from the optimal hypothesis, while adding new unbounded subsets to $\kappa$. In some ways these forcings are closer to the Cohen-type forcings—we show that they are not minimal—but, they share some properties with treelike forcings. We show that they admit fusion-type arguments which allow for a uniform lifting argument.

Esse estudo objetivou analisar a violência infantil no contexto brasileiro, correlacionando-a com fatores socioeconômicos, socioculturais, geracionais e de gênero, investigando o impacto dos mesmos na saúde das crianças. Realizou-se um estudo epidemiológico descritivo, realizado a partir de dados de artigos científicos e documentos oficiais sobre e violência infantil, além do banco de dados do Sistema de Informação de Agravos de Notificação (SINAN) e da plataforma SciELO e Google Acadêmico. Encontrou-se uma maior prevalência de violência física e negligência, maior índice de (...) violência sexual contra o sexo feminino e negligência no sexo masculino. Os principais agressores identificados foram o pai e a mãe. Acerca da etnia, crianças pardas foram as mais agredidas, bem como as de menor escolaridade. As consequências da violência infantil se estendem para além do momento da agressão, ao perturbar funções cognitivas e mesmo influenciar na gênese de transtornos psiquiátricos. (shrink)

Now in a third edition, Introduction to Philosophy: Classical and Contemporary Readings is a highly acclaimed, topically organized collection that covers five major areas of philosophy--theory of knowledge, philosophy of religion, philosophy of mind, freedom and determinism, and moral philosophy. Editor Louis P. Pojman enhances the text's topical organization by arranging the selections into a pro/con format to help students better understand opposing arguments. He also includes accessible introductions to each chapter, subsection, and individual reading, a unique feature for an (...) anthology of this depth. While the book focuses on a compelling sampling of classical material--including selections from Plato, Aristotle, Descartes, Locke, Berkeley, Hume, and Kant--it also incorporates some of philosophy's best twentieth-century and contemporary work, featuring articles by Bertrand Russell, Richard Taylor, John Searle, Thomas Nagel, and others. This third edition contains an expanded glossary, more extensive section introductions, and twelve new selections: Karl Popper: "Epistemology without a Knowing Subject" Richard Rorty: "Dismantling Truth: Solidarity Versus Objectivity" Daniel Dennett: "Postmodernism and Truth" Bruce Russell: "The Problem of Evil: Too Much Suffering" David Chalmers: "Against Materialism: Can Consciousness Be Reductively Explained?" Baron Paul Henri d'Holbach: "A Defense of Determinism" Michael Levin: "A Compatibilist Defense of Moral Responsibility" Plato: Socratic Morality: "Crito" Herodotus: "Custom Is King" J. L. Mackie: "The Subjectivity of Values" Louis P. Pojman: "A Critique of Mackie's Theory of Moral Subjectivism" Thomas Nagel: "Moral Luck". (shrink)

We show in ZFC that the existence of completely separable maximal almost disjoint families of subsets of $\omega $ implies that the modal logic $\mathbf {S4.1.2}$ is complete with respect to the Čech–Stone compactification of the natural numbers, the space $\beta \omega $. In the same fashion we prove that the modal logic $\mathbf {S4}$ is complete with respect to the space $\omega ^*=\beta \omega \setminus \omega $. This improves the results of G. Bezhanishvili and J. Harding in [4], where (...) the authors prove these theorems under stronger assumptions. Our proof is also somewhat simpler. (shrink)

This paper advances the research on personalization of political communication by investigating whether this process of focusing on politicians instead of political issues plays a role on Twitter. Results of a content analysis of 5,530 tweets posted in the run-up to the German federal election provide evidence that Twitter communication refers more often to politicians than to issues. However, tweets containing personal characteristics about political leaders play only a marginal role. When distinguishing among different groups of actors on Twitter (journalists, (...) politicians, citizens), we find that citizens focus more on candidates than do journalists or politicians. Investigating the impact of a televised debate on Twitter communication, we observe that this person-centered event puts the focus on individual politicians instead of issues. (shrink)

This article aims to read feminist new materialisms (Barad), together with ‘postulated’ linguistic or cultural primacy of Queer Theory (Butler), to show how both are engaged in similar critical-ethical endeavours. The central argument is that the criticism of Barad and new materialisms misses Butler’s materialistic insights due to a narrow interpretation of Butler's alleged social-constructivist position. There is, therefore, a specific focus on where they both make similar ethical appeals. Moreover, the article relies on Adorno's negative dialectic to highlight an (...) interpretation of Barad and Butler as being part of the same dialectical movement, in which materialism and idealism fluctuate in their mutual criticisms, thus continuing the procession towards 'new knowledge' and emancipation, or freedom, through their motions back and forth.

Given a countable model of set theory, we study the structure of its generic multiverse, the collection of its forcing extensions and ground models, ordered by inclusion. Mostowski showed that any finite poset embeds into the generic multiverse while preserving the nonexistence of upper bounds. We obtain several improvements of his result, using what we call the blockchain construction to build generic objects with varying degrees of mutual genericity. The method accommodates certain infinite posets, and we can realize these embeddings (...) via a wide variety of forcing notions, while providing control over lower bounds as well. We also give a generalization to class forcing in the context of second-order set theory, and exhibit some further structure in the generic multiverse, such as the existence of exact pairs. (shrink)

This baseline study was conducted to find out the knowledge, attitudes and practices of medical ethics among the undergraduate medical interns who did not have structured ethics curriculum in their course. A descriptive, cross-sectional study was carried out using a self-administered structured questionnaire among the medical undergraduate interns of Maharajgunj Medical Campus, the pioneer medical college of Nepal which enrols 60 students in a year. A total of 46 interns participated in the study. The most common source of knowledge on (...) ethics was lectures/seminars (35.7%) followed by experience at work (24.5%), training (21.4%) and own reading (17.3%). The main contents of Hippocratic Oath were known to 98.8% while 60.9% knew the main contents of Nepal Medical Council (NMC) code of ethics. Great majority (91.3%) regard ethics as very important in medical profession. “Doctors know the best irrespective of patients’ opinion” was disagreed by only 39.1% indicating the paternalistic attitude. However, 78.3% were in favour of adhering to the patient’s wish. None of the participant agreed to abandon confidentiality. Only about one-fourth (26.1%) claim to encounter ethical dilemma every day while the highest number (43.5%) had once in a month. To deal with the situation of ethical dilemma, majority approached to immediate supervisor followed by head of the department and colleagues. Eighty-seven percent of participating interns were involved in research activities involving human subjects. Only one of the participants had encountered the ethical issue on end-of-life and it was do-not-resuscitate consent in a terminally ill patient. On implementation of the curriculum on medical ethics focus should be - principles of biomedical ethics, sensitive ethical dilemmas like end-of-life care and practical experiences with participation in deliberations of the ethics committee.

The formation of the World Anti-Doping Agency in 1999 was spurred by the 1998 revelation of widespread use in professional cycling of erythropoietin. The drug was supposedly a real danger. The long-term consequences were unknown, but rumor said it made athletes’ blood thick as jam with clots and other circulatory fatalities likely consequences. Today the fear of EPO has dampened. However, new scientific avenues such as ‘neuro-doping’ have replaced EPO as emergent and imagined threats to athletes and to the integrity (...) of sport. In this paper, we analyze the alleged threat from ‘neuro-doping’ in the following steps: First, we outline an understanding of ‘neuro-doping’ in a narrow sense, which we then put into context by looking at the phenomenon in a broader sense. Second, we highlight examples of societal perceptions of sport and science in order to shed light on where the concern for ‘neuro-doping’ comes from. Third, we address the more general fear of technology as a root for this concern. Fourth, we examine the evidence for the performance enhancing capacities of ‘neuro-doping’, where after we look at the obstacles for a ban on this technology. We conclude the analysis by stating that at present ‘neuro-doping’ cannot be considered a threat to the integrity of sport. Finally, however, we put this conclusion into perspective by examining what the most reasonable response would be if in the future neuro-stimulation techniques becomes an effective performance-enhancing mean in sport.

Since the end of the Second World War, the popularity of modern elite sport has grown immensely and so has the economical interests in sport. Athletes have become attractive advertising partners. Much money is at stake so it is understandable that companies are alarmed when their poster boys or girls are caught up in scandals. Inspired by a recent study, which found that stock return of primary team sponsors in cycling was not affected if the team was involved in doping (...) scandals, this paper is an attempt to explain why athletes often maintain their marketing value even if they are exposed as bad role models. The thesis is that the attraction of athletes relates to the concept of ‘charisma’, and that the success of mass spectator sports is due to sport’s appeal to what psychologist Henry Rutgers Marshall by the end of the 19th Century in an article in Mind identified as man’s ‘religious instinct’. So after a brief introduction, the paper begins with a clarification of the antiquated concept ‘religious instinct’. This is followed by a critical examination of the secular usage of ‘charisma’ as introduced by Max Weber. Peter Sloterdijk’s sobering point that Hitler’s aptitude for his role in Germany did not rely on charisma lays the foundation for a more precise and rationally consistent description of the concept. It is argued that charisma is not something certain individuals posses, rather it is something that is experienced as an emotional effect by those who label individuals charismatic, which is based on the honesty competence and commitment of the perceived ‘charismatic’ person. Idols can have charismatic effect on us even if they are unprincipled cheats so long as they are committed to what they do. This is why athletes maintain their appeal and marketing value so long as their performances transcend the capabilities of ordinary people. (shrink)
