Zaller's model of public-opinion formation portrays the average citizen as an automaton who responds unthinkingly to elite cues. That is, once people have received information from political elites, they tend to abide by whatever their respective cue-givers dictate, since rejecting information is more cognitively costly than simply accepting it. Empirical research in psychology on priming supports this view of the citizen as a passive receiver of information. For example, people are likely to be unconsciously influenced by subtle cues and they (...) tend to base their opinions on the accessibility of information in memory. However, some citizens, under certain conditions, may be ?active processors? of information: actively interpreting it, elaborating on its implications, and negotiating its meaning. Whether or not Zaller's model is an accurate representation of the process of public-opinion formation depends substantially upon the inclusiveness of the researcher's views about what constitutes public opinion and how to study its determinants.

A shift in emphasis can change the truth-value of a singular causal sentence. This poses a challenge to the view that singular sentences predicate a relation. I argue that emphasized causal sentences conjoin predication of a causal relation between events with predication of a relation of causal relevance between states of affairs (or perhaps facts). This is superior to the treatments of such sentences offered by Achinstein, Dretske, Kim, Sanford, Bennett, and Levin. My proposal affords clarity regarding logical structure, at (...) least at a certain level of detail. It makes the relation between the content of an emphasized causal sentence and the unemphasized version clear. It answers some questions about the ontological requirements of the truth of emphasized causal sentences, without introducing new entities (as do some other accounts) or unacceptable consequences for identity and individuation of events.

The starting point of the present study is to investigate which environmental factors play a role in the media behavior of ethnic minority youth. To what extent do socio-demographic characteristics influence ownership and use of the media? We also address the role of religion, cultural origin and the cultural distance between ethnic minority youth and indigenous Dutch youth. Three numerically important groups of ethnic minority youth are discussed: Turks, Moroccans and Surinamese. In a survey conducted among Turkish, Moroccan and Surinamese (...) youth aged between 12 and 19, residing in the Netherlands, we investigated which environmental factors play a role in the media behavior of ethnic minority youth. A control group of indigenous Dutch youth was established and likewise exposed to the variables under study. (shrink)

High-profile corporate scandals earlier in this decade provoked outrage and legislative action; however, corporate executive-level ethical lapses continue to come to light. This article examines the work of Professor Dunfee and his coauthors on corruption, ethical leadership, and social contracts theory, and relates that literature to corrupt activities by corporate executives. Corruption is defined broadly to encompass executive self-dealing, which harms their firms. The specific example of stock options backdating is used to show the harmful impact on shareholders and the (...) lack of managerial integrity though consequentialist, deontological, and legal analysis, as well as a critique of the practice using social contracts principles. Ultimately, this article utilizes the insights of Dunfee and his coauthors, and the lessons from the backdating example, to propose a framework aimed at improving corporate governance and preventing future executive corruption. The framework includes a strategy of identification and prevention, employing detection and eradication mechanisms, and institutional learning from past instances of corporate corruption. (shrink)

Recent research has focused on business as a mediating institution that can influence society while engaging in the traditional profit-making and value generation functions. This work includes Professors Fort's and Schipani's arguments about how business may be able to play a role in promoting more peaceful societies, and other research addressing how businesses might serve a role in reducing violence in society and the workplace. Although there is a significant body of scholarship on the role of business in reducing violence (...) in society, there is little research on concrete steps for businesses to take to achieve this goal. This article attempts to begin to fill that void. As identified by Fort and Schipani, business may promote more peaceful societies by encouraging a sense of community. We argue that one way to reach that goal is for business to provide what we denote as complementary alternative benefits (CABs), to its workforce. In this article, we advocate for businesses to offer CABs which focus on sustaining the health, reducing the stress, and improving the camaraderie of its workforce. We argue that business can use these benefits to promote a healthy, less-stressed, and collegial workforce that is less prone to resolve conflicts by violence. Further, we examine the role business plays in promoting more peaceful societies and how employer-initiated stress reduction programs are consistent with both business ethics and peace-building principles. Finally, using case studies we demonstrate how CABs may also reduce costs related to absenteeism and turnover, and thus improve the bottom line. (shrink)

Discussion of the ethics of forgoing medically provided nutrition and hydration tends to focus on adults rather than infants and children. Many appellate court decisions address the legal propriety of forgoing medically provided nutritional support of adults, but only a few have ruled on pediatric cases that pose the same issue.The cessation of nutritional support is implemented most commonly for patients in a permanent vegetative state ). An estimated 4,000 to 10,000 American children are in the permanent vegetative state, compared (...) to 10,000 to 25,000 adults. Yet the dearth of literature, case reports, and court decisions suggests that physicians and families of pediatric patients stop medically provided nutrition or seek court orders much less frequently.

The operator structures for the constants of the motion of the relativistic hydrogen atom are examined. ThoughJ 3 andJ · J are constants of the motion,J is not. Its replacement, $\tilde {\rm K}$ , is shown to emerge rather naturally in transforming the equation to spherical coordinates. The separation of variables is presented in hypercomplex number form. This leads to some interesting suggestions regarding the matter/antimatter operator for the Dirac equation.

A new four-component spin-1/2 wave equation for ordinary mass is discussed. It is shown that this equation has a conserved current not easily identified with a transition probability, only pure imaginary energy states, and is covariant. A tachyon-like Klein-Gordon equation is satisfied by this equation, but rest states are explicitly constructed.

A survey is presented of the essential principles for formulating relativistic wave equations in curved spacetime. The approach is relatively simple and avoids much of the philosophical debate about covariance principles, which is also indicated. Hypercomplex numbers provide a natural language for covariance symmetry and the two important kinds of covariant derivative.

A “mental” multiplication scheme is given for the super hypercomplex numbers, which extend the 16-element Dirac algebra to 32 elements by appending the complex octonions. This extends the 5-vectors of relativity to 9-vectors. The problems with nonassociativity, for the group structures and wave equation covariance, are explored.

The basic structure of a second quantized relativistic quantum theory is outlined. The vector space is over the ring of complex quaternions instead of the usual field of complex numbers. This is motivated by the simple quaternion structure of the Dirac equation.

Background: Editorial peer review is universally used but little studied. We examined the relationship between external reviewers' recommendations and the editorial outcome of manuscripts undergoing external peer-review at the Journal of General Internal Medicine. Methodology/Principal Findings: We examined reviewer recommendations and editors' decisions at JGIM between 2004 and 2008. For manuscripts undergoing peer review, we calculated chance-corrected agreement among reviewers on recommendations to reject versus accept or revise. Using mixed effects logistic regression models, we estimated intra-class correlation coefficients at the (...) reviewer and manuscript level. Finally, we examined the probability of rejection in relation to reviewer agreement and disagreement. The 2264 manuscripts sent for external review during the study period received 5881 reviews provided by 2916 reviewers; 28% of reviews recommended rejection. Chance corrected agreement on rejection among reviewers was 0.11. In mixed effects models adjusting for study year and manuscript type, the reviewer-level ICC was 0.23 and the manuscript-level ICC was 0.17. The editors' overall rejection rate was 48%: 88% when all reviewers for a manuscript agreed on rejection and 20% when all reviewers agreed that the manuscript should not be rejected. Conclusions/Significance: Reviewers at JGIM agreed on recommendations to reject vs. accept/revise at levels barely beyond chance, yet editors placed considerable weight on reviewers' recommendations. Efforts are needed to improve the reliability of the peer-review process while helping editors understand the limitations of reviewers' recommendations. © 2010 Kravitz et al. (shrink)

Mentoring Away the Glass Ceiling in Academia: A Cultured Critique describes how women of diverse backgrounds perceive their mentoring experiences or the lack of mentoring experiences in the academy. This book provides a space for envisioning strategies and practices to improve mentoring practices and the collegiate environment.

La 4e de couverture indique : "Cet ouvrage est écrit à quatre mains et porte sur la relation entre création artistique et sciences de la cognition. L'ouvrage propose deux approches de l'expérience esthétique. Une approche en troisième personne mobilisant des modèles propres aux systèmes dits auto-organisateurs issus de la biologie dédiée à la réception des œuvres d'art et une approche en première personne rendant compte par auto-analyse d'une pratique artistique vécue qui s'appuie également sur de tels systèmes, systèmes eux-mêmes liés (...) aux concepts d'émergence et de complexité".

A self-consistent relativistic formalism is presented which postulates that mass is the eigenvalue of a fifth momentum operator component. Lorentz covariance is generalized so that a systematic program for covariant wave equations can be formed. The fifth dimension is identified with cosmic time, resulting in a bias toward matter over antimatter for the universe. A distinction between μ ande also seems possible through the space-time extension.

Partons (quarks) are unobservable, it is suggested, because they have no well-defined rest-massconcept.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Exception from Informed Consent (EFIC) regulations detail specific circumstances in which Institutional Review Boards (IRB) can approve studies where obtaining informed consent is not possible prior to subject enrollment.To better understand how IRB members evaluate community consultation (CC) and public disclosure (PD) processes and results, semi-structured interviews of EFIC-experienced IRB members were conducted and analyzed using thematic analysis.Interviews with 11 IRB members revealed similar approaches to reviewing EFIC studies. Most use summaries of CC activities to determine community members’ attitudes; none (...) reported using specific criteria nor recalled any CC reviews that resulted in modifications to or denials of EFIC studies. Most interviewees thought metrics based on Community VOICES’s domains (feasibility, participant selection, quality of communication, community perceptions, investigator/IRB perceptions) would be helpful.IRB members had similar experiences and concerns about reviewing EFIC studies. Development of metrics to assess CC processes may be useful to IRBs reviewing EFIC studies. (shrink)

Dans un passage de Physique iii (7, 207b15-21), Aristote s’exprime d’une manière qui suppose valide l’implication suivante : « Si une grandeur peut être infinie en puissance, une telle grandeur peut aussi être infinie en acte ». Cette implication a intrigué les commentateurs tant anciens et médiévaux que modernes. Ces derniers se sont en général bornés à constater que l’implication n’est pas logiquement valide, sans expliquer comment et en quel sens Aristote avait pu la tenir pour telle. En rapprochant le (...) passage précité d’un autre passage de Physique iii (6, 206b16-27), le présent article en propose une interprétation qui semble lever toutes les difficultés. Au Moyen Age, le sens de l’implication a été très discuté, et l’interprétation proposée ici a été vue et soutenue par plusieurs commentateurs : on l’étudie chez quelques-uns de ceux-ci en situant leur position dans le cadre du débat médiéval sur la question, notamment en référence aux deux interprétations alors fameuses proposées par Averroès.

Voilà un ouvrage d’une grande originalité, si grande qu’un spécialiste aussi consommé de la biologie aristotélicienne que Pierre Pellegrin – qui préface le livre – peut écrire (p. 10) : « Mes années d’études ne me donnent pas plus de compétence que n’en a n’importe quel lecteur nouveau du corpus biologique aristotélicien pour apprécier un travail aussi neuf ». Quant à moi, je ne saurais mieux faire, pour en donner une première idée, que d’emprunter quelques phrases à cette préface : (...) « […] l.. (shrink)

Examen de la philosophie de l'analyse structurale, analysant terme à terme les rapports entre la forme et le sens et débouchant sur une réflexion concernant les concepts annexes d'expression, de signal, de signe, de symbole, de langage et de discours.

In this paper our aim is to augment the value-congruency literature by demonstrating the dynamics of business value structures. The relationship between cognitive discomforts and value restructuring is examined by applying self-affirmation theory. Subjects (N = 115) were randomly assigned either to the treatment group (n = 69) or control group (n = 46). Those subjects in the treatment group were tasked with deciding between two different organizational re-structuring options that involved downsizing. The values of job-entitlement, and obligations to the (...) disadvantaged shifted in emphasis in a direction that legitimated and justified the lay-off decision. The value of economic nationalism remained unchanged. Implications for research and practice are discussed. (shrink)
