By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discussed. It is concluded that, although from the point of view of representation theory there are no compelling reasons to choose between spin-2 waves with helicity σ=±1 or σ=±2, consistency arguments of the ensuing field theories favor waves with helicity σ=±1.

The aim of this article is to offer what I consider to be necessary substantiati for the view that the description of the walk which acts as a frame for the singing contest in Id. 7 is based on a precise knowledge of the geography of t island of Cos and that the poem thus displays a topographical realism unique Greek pastoral.

The aim of this paper is to challenge the claim that the neural activity commonly referred to as 'readiness potential' constitutes evidence for the unconscious initiation of action. Although I accept that such neural activity seriously challenges the commonly held view that one's sense of volition is causally efficacious, I nevertheless contend that much of our everyday engagement with the world is consciously initiated. Thus, a distinction is made between awareness and what the awareness is of: the latter constituting the (...) conscious decision to act in accordance with one's goal, or what I have termed intentional project. Initiation of an action in accordance with one's intentional project grounds the action in meaning, something that would be lacking in an exclusively unconscious decision to act. (shrink)

The problems of this passage were concisely stated by M. Platnauer more than thirty years ago and his suggestions for their solution have been adopted and developed in A. S. F. Gow's magnum opus. Its authority—so the present writer suspects—is liable at this point to eclipse the meaning of the text.

Offering both a discussion of feminism in its postmodern context and a critique of contemporary theory, the author here challenges feminists to move away from a theory-based approach, which focuses on securing or contesting "women" as an ...

ABSTRACT:Neuroethics, the study of the cognitive and neural mechanisms underlying ethical decision-making, is a growing field of study. In this review, we identify and discuss four themes emerging from neuroethics research. First, ethical decision-making appears to be distinct from other types of decision-making processes. Second, ethical decision-making entails more than just conscious reasoning. Third, emotion plays a critical role in ethical decision-making, at least under certain circumstances. Lastly, normative approaches to morality have distinct, underlying neural mechanisms. On the basis of (...) these themes, we draw implications for research in business ethics and the practice of ethics training. (shrink)

We develop measure theory in the context of subsystems of second order arithmetic with restricted induction. We introduce a combinatorial principleWWKL (weak-weak König's lemma) and prove that it is strictly weaker thanWKL (weak König's lemma). We show thatWWKL is equivalent to a formal version of the statement that Lebesgue measure is countably additive on open sets. We also show thatWWKL is equivalent to a formal version of the statement that any Borel measure on a compact metric space is countably additive (...) on open sets. (shrink)

In recent years, the practices of work organizations have raised increasing concerns regarding individual privacy at work. It is clear that people expect and value privacy in their personal lives. However, the extent to which privacy perceptions influence individuals’ work attitudes is less clear. Research has explored the extent to which employee perceptions of privacy derive from characteristics of the programs themselves. However, there is a paucity of research that examines how the characteristics of the individual employee may influence perceptions (...) of these programs. In this study we seek to shed light on this issue, as we examine how the individual ethical orientation of employees influences perceptions of a variety of human resource programs that have the potential to be perceived as invasive. Results indicate that ethical orientation exerts direct effects on perceived invasiveness of programs and exerts both direct and indirect effects on perceived appropriateness of programs. Implications for research and for managers adopting privacy-related programs are discussed. (shrink)

I want to suggest that Plato arrived at a revised theory of forms in the later dialogues. Or perhaps I might rather say that he constructed a new underpinning for the theory. This can be discerned, I believe, in the Sophist, taken together with certain parts of the dialectic of the Parmenides which use the same language as the Sophist.

This book comprises material on colour which was written by Wittgenstein in the last eighteen months of his life. It is one of the few documents which shows him concentratedly at work on a single philosophical issue. The principal theme is the features of different colours, of different kinds of colour and of luminosity—a theme which Wittgenstein treats in such a way as to destroy the traditional idea that colour is a simple and logically uniform kind of thing. This edition (...) consists of Wittgenstein's basic German text, together with an English translation. (shrink)

This paper introduces a generalization of Reiter’s notion of “extension” for default logic. The main difference from the original version mainly lies in the way conflicts among defaults are handled: in particular, this notion of “general extension” allows defaults not explicitly triggered to pre-empt other defaults. A consequence of the adoption of such a notion of extension is that the collection of all the general extensions of a default theory turns out to have a nontrivial algebraic structure. This fact has (...) two major technical fall-outs: first, it turns out that every default theory has a general extension; second, general extensions allow one to define a well-behaved, skeptical relation of defeasible consequence for default theories, satisfying the principles of Reflexivity, Cut, and Cautious Monotonicity formulated by D. Gabbay. (shrink)

Two different models for chemical bond were developed almost simultaneously after the Schrödinger formulation of quantum theory. These are known as the valence bond (VB) and molecular orbital (MO) theories. Initially chemists preferred the VB theory and ignored the MO theory. Now the VB theory is almost dropped out of currency. The context of discovery and Linus Pauling’s overpowering influence gave the VB theory its initial advantage. The current universal acceptance of the MO theory is due to its ability to (...) provide direct interpretation of many different types of experiments now being pursued. In current research both localized bonds and delocalized charge distributions play important roles and the MO theory has been successful in giving a good account of both. (shrink)

Yaygın din eğitimi örgün din eğitimin dışında bireylerin dini ihtiyaçlarını gidermek için resmi ya da özel kuruluşlar vasıtasıyla her bireye planlı ve amaçlı olarak verilen eğitimdir. Günümüzde yaygın din eğitimini şekillendiren temel kurum Diyanet İşleri Başkanlığıdır. Diyanet İşleri Başkanlığı yaygın din eğitimini cami içi ve cami dışı olarak yerine getirmektedir. Cami içi yaygın din eğitimi ise; vaaz, hutbe ve kuran öğretimi ile yapılmaktadır. Bu eğitimlerden olan hutbe, Müslümanları ilgilendiren bütün konuları ele alarak topluma dini bilgileri öğretmek; insanlarda olumlu yönde davranış (...) değişikliği oluşturmak, hedef kitlenin iman, ahlak ve toplumsal farkındalık bakımından duyarlı hale gelmesini sağlamak için bireylere yardımcı olmaktır. Yaklaşık olarak aynı dönemlerde doğmuş, aynı dönemin özelliklerini paylaşmış, benzer sorumluluklara sahip bireyler aynı kuşak bireyleri olarak tanımlanır. 1990-2015 yılları arasında doğmuş büyümüş bireyler Z kuşağı bireyleri olarak adlandırılmaktadır. Bu kuşak bireyleri interneti kullanma, teknolojiyi sevme, görsele aşina, üretken ve eşitlikçi gibi özelliklere sahiptir. Bu durum Z kuşağının sosyalleşmesinde, yaşam alışkanlıklarında ve öğrenme sitillerinde farklıları beraberinde getirmiştir. Yaygın din eğitim nesiller arasındaki bu farklılıkları dikkate alarak bireylerin kendilerini geliştirmelerine ve bilgilerini güncellemelerine yardım etmelidir. Bu sebeple yaygın din eğitimi Z kuşağının ihtiyaçlarını dikkate alarak farklı metot ve etkinlikleri geliştirmesi gerekir. Bu bağlamda Z kuşağının gözüyle Cuma hutbelerinin nasıllığı önemli hale gelmektedir. Buradan hareketle Z kuşağının Cuma hutbelerine karşı tutumlarını incelemek için Cuma hutbeleri değerlendirilmiştir. Araştırmamız, Z kuşağının Cuma Hutbelerini algılamalarını incelemek amacıyla tanımlayıcı araştırma tasarımı ile yürütülmüştür. Araştırmanın evrenini Konya İli Seydişehir, Beyşehir ilçesinde 14-25 yaş aralığındaki 175 birey oluşturmaktadır. Veriler araştırmacılar tarafından hazırlanan ‘Birey Tanılama Formu’ ve ‘Cuma Hutbelerine İlişkin Bilgi Formu’ aracılığıyla toplanmıştır. Araştırmada, verilerin analizinde IBM SPSS (IBM Statistical Package for Social Sciences Corp.; Armonk, NY, ABD) 25.0 programı kullanılmıştır. Araştırma verileri değerlendirilirken kategorik değişkenler için frekans dağılımı (sayı, yüzde), sayısal değişkenler için tanımlayıcı istatistikler (ortalama, standart sapma) kullanılmıştır. Araştırmaya katılan katılımcıların yaş ortalamaları 17.04’dir. Katılımcıların çoğunluğunun lise öğrencisi olduğu görülmüştür. Araştırmada Z kuşağının Cuma hutbelerine katılım sağladığı, hutbelerden umut bekledikleri, olumlu yönden etkilendikleri görülmüştür. Ancak Cuma hutbelerindeki konuların yerel ve güncel konuları ele almadığı ifade ederek anlatılan konuların hatırlamadıkları, aynı konuların tekrar ettiği, gençlere yönelik olmadığına ulaşılmıştır. Ayrıca hutbelerin sunumu, süresi ve imamların yaklaşımlarından dolayı problemler yaşandığı tespit edilmiştir. (shrink)

The UNESCO Universal Declaration on Bioethics and Human Rights of 2005 purports to articulate universal norms for bioethics. However, this document has met with mixed reviews. Some deny that the elaboration of universal bioethics norms is needed; some deny that UNESCO has the expertise or authority to articulate such norms; some regard the content of the UNESCO document as too vague or general to be useful; and some regard the document as a cog in the effort of like-minded cosmopolitans to (...) codify their particular moral intuitions in international law. This issue examines the potential merits and pitfalls of the Universal Declaration on Bioethics and Human Rights. (shrink)

Past research has found that skin colouration, particularly facial redness, influences the perceived health and emotional state of target individuals. In the current work, we explore several extensions of this past research. In Experiment 1, we manipulated facial redness incrementally on neutral and angry faces and had participants rate each face for anger and health. Different red effects emerged, as perceived anger increased in a linear manner as facial redness increased. Health ratings instead showed a curvilinear trend, as both extreme (...) paleness and redness were rated as less healthy than moderate levels of red. Experiment 2 replicated and extended these findings by manipulating the masculinity of both angry and neutral faces that varied in redness. The results found the effect of red on perceived anger and health was moderated by masculine face structure. Collectively, these results show that facial redness has context dependent effects that vary based on facial expression, appearance, and differentially impact ratings of emotional states and health.
