The impact of background category information on the creation of social cliques: The role of need for cognitive closure and decisiveness This article focuses on the role of need for cognitive closure in the process of mental model creation about social relations. We assumed that high need for closure participants tend to rely on background category information when forming social cliques. We predicted that this tendency to employ categorical information as a mental aid, used in order to form social cliques, (...) would be efficient in simple task structures but would lead to increased error rates in complex task structures. The results confirmed our predictions, showing especially strong effects for the decisiveness component of need for closure. The importance of individual differences in need for closure and decisiveness in social reasoning is discussed. (shrink)
Research investigating the underlying mechanisms and boundary conditions under which leader humility influences employee voice remains underdeveloped. Drawing from approach–inhibition theory of power and leader humility literature, we developed a moderated-mediation model in which personal sense of power was theorized as a unique mechanism underlining why employees feel motivated to speak up under the supervision of humble leaders. Additionally, the cultural value of power distance was proposed to be a relevant boundary condition to influence such relationship. We tested the model (...) using time-lagged supervisor–subordinate matched data. Results of mixed models analyses provided support for our hypotheses confirming that employees’ personal sense of power mediates the relationship between leader humility and employee voice, and such relationship was found to be stronger when employees’ power distance was lower rather than higher.

Motherland under attack! Nationalism, terrorist threat, and support for the restriction of civil liberties The paper addresses the role which national attitudes play in terrorist threat perception and in the choice of specific counterterrorism strategies. Study 1 shows that participants higher on nationalism tend to perceive the threat of terrorism as more serious than participants lower on nationalism. Moreover, we found that nationalism mediated the relationship between the perceived terrorist threat and the support for tough domestic policies, even at the (...) expense of considerable limitation of civil liberties. Study 2 confirms the link between the perceived terrorism threat and the support for suspension of civil liberties. Nevertheless, when terrorism was seen in terms of crime rather than in terms of war, the mediating role of nationalism disappeared. The results contribute to a better understanding of the process whereby the perception of one's own national group and the perception of one's own nation-state translate into specific reactions triggered by external threats.

The aim of this research was to examine the impact of two specific negative emotions of anger and fear on intergroup attitudes. In Study 1 we measured emotions of anger and fear and in Study 2 we evoked these emotions incidentally, that is independently of any intergroup context. In both studies we measured attitudes towards the ingroup and the outgroup.We expected that fear would lead to more positive ingroup attitudes and anger to more negative outgroup attitudes. The results of the (...) correlational study confirmed the predictions regarding anger and decreased outgroup evaluations, and the experimental study revealed that fear enhanced positivity towards the ingroup, but anger increased negativity towards the outgroup. The impact of fear and anger on social attitudes in the specific context of a negatively self-stereotyped ingroup is discussed. (shrink)
Prior studies have demonstrated that social-cognitive factors such as children’s false-belief understanding and parenting style are related to children’s lie-telling behaviors. The present study aimed to investigate how earlier forms of theory-of-mind understanding contribute to children’s lie-telling as well as how parenting practices are related to children’s antisocial lie-telling behaviors. Seventy-three three-year-olds from Hangzhou, P. R. China were asked not to peek at a toy in the experimenter’s absence. The majority of children who peeked, lied about it. Children’s lies were (...) positively related to performance on the knowledge-ignorance theory-of-mind task. Additionally, Control parenting, characterized by high levels of monitoring and demanding, unquestioning obedience, was negatively related to three-year-olds’ lying. The relation between Control parenting and lie-telling was partially mediated by children’s theory-of-mind understanding. These findings suggest that children’s early lie-telling behaviors are influenced by social and social-cognitive factors. (shrink)
Ma and Sun have recently argued that some forms of insider trading are ethically acceptable. We argue that the authors fail to prove three key premises of their argument, which is therefore unsound.
Freiheitsentziehende Maßnahmen in Altenpflegeheimen sind unter pflegerischen und ethischen, aber auch betreuungsrechtlichen und vor allem strafrechtlichen Gesichtspunkten von besonderer Bedeutung. Häufig sind eingeschränkte Mobilität, Verringerung der kognitiven Funktionen, große Hilfsbedürftigkeit des älteren Menschen der auslösende Faktor für den Einsatz derartiger Einschränkungen. Daneben gibt es jedoch Hinweise, dass die Anwendung freiheitsentziehender Maßnahmen auch mit organisatorischen Abläufen in Altenpflegeeinrichtungen zusammenhängt. Der vorliegende Beitrag diskutiert, wieweit freiheitsentziehende und freiheitsbeschränkende Maßnahmen bei alten Menschen überhaupt zulässig sind und zeigt auf, dass die Entwicklung von alternativen (...) Betreuungs- und Versorgungsansätzen dazu beitragen kann, dass durch weniger freiheitsentziehende Maßnahmen in der stationären Pflege die Würde der alten Menschen gewahrt bleibt. (shrink)
As volunteer engagement in non-governmental organizations vary between individuals, it is vital to get to know its predictors. It can be of profit to volunteers and the ones who profit from their activities. The aim of present study was to examine a model explaining volunteer engagement examining volunteer self-efficacy as a mediator and personality traits, job resources as its predictors. Respondents were asked to fill in questionnaires accessible online. Those consisted of demographic questions as well as Ten-item Personality Inventory, and (...) three measures adjusted to volunteer environment: Work Design Questionnaire, General Self-Efficacy Scale, and Work Engagement Scale. Results. Results of hierarchical regression analyses showed that conscientiousness, skill variety and self-efficacy are statistically significant predictors of volunteer engagement. It was shown that the effects of conscientiousness and skill variety on volunteer engagement are mediated by volunteer self-efficacy. (shrink)
Over the past decade, ethical leadership has increasingly become one of the most popular topics in the areas of leadership and business ethics. As a result, there now exists a substantial body of empirical research addressing ethical leadership issues, but the findings reported by this body of research are highly fragmented. The topic has advanced to the stage where a review and synthesis of existing literature can provide great value and help move the scholarly conversation forward. The primary purposes of (...) this article are to review empirical findings from the ethical leadership literature utilizing a framework consisting of the antecedents, mediators, moderators and outcomes of ethical leadership, and suggest a set of interesting research opportunities, thereby facilitating future investigation. We base our synthesis on a review of 62 empirical studies on ethical leadership that were published between 2005 and mid-2015. (shrink)
This book traces a most obscure and yet most intriguing theme concealed in Heidegger’s thinking and work, which has hitherto not yet been made the focus of a thorough and sustained investigation: that is, the emergence and course of Heidegger’s interest in East Asian thought and of his reflection on East-West dialogue. Lin Ma covers such complex issues as Heidegger’s thoughts on language, Being, technology, the other beginning, and the journey abroad, with a view to their implications for East-West dialogue. (...) It reveals the significance of his remarks on the early Greek’s confrontation with the Asiatic, and presents contextualized interpretations of his fleeting references to the topic of East-West dialogue and of his encounter with the Daodejing. Finally, it delves into "A dialogue on language" and exposes the strains and tensions that accompany Heidegger’s extension of dialogue and the Same, the two notions central to his thought, to the question of East-West dialogue. In the end, Lin Ma concludes that Heidegger’s fundamental concerns and philosophical orientations as articulated in terms of the history of Being and the other beginning have restricted him from engaging more seriously with the irresolvable and yet enduring issue of East-West dialogue.

We consider an implementation of the discounted Shapley value. We modify the Hart–Mas-Colell model such that each player discounts future payoffs and proposes not only an allocation, but also a coalition. We show that the discounted Shapley value is supported by each stationary subgame perfect equilibrium of the modified game such that in each subgame, the coalition that consists of all active players immediately forms. We also provide conditions for such a stationary subgame perfect equilibrium to exist.
Finance ethics have drawn increasing attention from both government regulators and academic researchers. This paper addresses the issue of insider trading ethics. Previous studies on insider trading ethics have failed to provide convincing arguments and consistent results. In particular, the arguments against insider trading are based primarily on moral and philosophical grounds and lack empirical rigor. This study intends to establish and examine the relationship between the ethical issue and economic issue of insider trading. We argue that the ethics of (...) insider trading is in essence an economic rather than a moral issue. It is so far not clear to what extent insider trading may increase or decrease shareholders wealth. Until then, we must take care to avoid over-regulating insider trading. (shrink)
We show that externalization is a feature not only of moral judgment, but also of value judgment in general. It follows that the evolution of externalization was not specific to moral judgment. Second, we argue that value judgments cannot be decoupled from the level of motivations and preferences, which, in the moral case, rely on intersubjective bonds and claims.
Individual differences in decisiveness: pre-decisional information search and decision strategy use We investigated whether individual differences in decisiveness are associated with a tendency to use different decision strategies during pre-decisional information search. To explore these potential links we administered the Need for Cognitive Closure questionnaire to 62 participants, followed by a probabilistic inference, multi-attribute choice task. Participants high in decisiveness dimension, compared to ‘low decisives’, spent less time and acquired less information prior to making decisions, especially in the first trials (...) of the choice task. ‘High decisives’ also had a greater tendency to use a simple Lexicographic heuristic than ‘low decisives’. The results support the view that high decisiveness is associated with greater tendency to simplify the decision process. (shrink)
A deterministic weakening \ of the Belnap–Dunn four-valued logic \ is introduced to formalize the acceptance and rejection of a proposition at a state in a linearly ordered informational frame with persistent valuations. The logic \ is formalized as a sequent calculus. The completeness and decidability of \ with respect to relational semantics are shown in terms of normal forms. From an algebraic perspective, the class of all algebras for \ is described, and found to be a subvariety of Berman’s (...) variety \. Every linearly ordered frame is logically equivalent to its dual algebra. It is proved that \ is the logic of a nine-element distributive lattice with a negation. Moreover, \ is embedded into \ by Glivenko’s double-negation translation. (shrink)
Fecal microbiota transplantation has demonstrated efficacy and is increasingly being used in the treatment of patients with recurrent Clostridium difficile infection. Despite a lack of high-quality trials to provide more information on the long-term effects of FMT, there has been great enthusiasm about the potential for expanding its applications. However, FMT presents many serious ethical and social challenges that must be addressed as part of a successful regulatory policy response. In this article, we draw on a sample of the scientific (...) and bioethics literatures to examine clusters of ethical and social issues arising in five main areas: informed consent and the vulnerability of patients; determining what a “suitable healthy donor” is; safety and risk; commercialization and potential exploitation of vulnerable patients; and public health implications. We find that these issues are complex and worthy of careful consideration by health care professionals. Desperation of a patient should not be the basis for selecting treatment with FMT, and the patient's interests should always be of paramount concern. Authorities must prioritize development of appropriate and effective regulation of FMT to safeguard patients and donors, promote further research into safety and efficacy, and avoid abuse of the treatment.

This paper criticizes the pragma-dialectical conception of a fallacy, according to which a fallacy is an argumentative speech act which violates one or more of the rules of 'rational discussion'. That conception is found to be neither a necessary nor a sufficient condition for committing a fallacy. It is also found wanting in several other respects.

We describe Peirce’s 1903 system of modal gamma graphs, its transformation rules of inference, and the interpretation of the broken-cut modal operator. We show that Peirce proposed the normality rule in his gamma system. We then show how various normal modal logics arise from Peirce’s assumptions concerning the broken-cut notation. By developing an algebraic semantics we establish the completeness of fifteen modal logics of gamma graphs. We show that, besides logical necessity and possibility, Peirce proposed an epistemic interpretation of the (...) broken-cut modality, and that he was led to analyze constructions of knowledge in the style of epistemic logic.

In the present study the impact of need for cognitive closure manipulations via time pressure and explicit closure goal activation on executive control was investigated. Although there is some evidence that NFC, measured as an individual variable, is related to better performing in attentional tasks involving executive control, these results have never been validated across different manipulations of NFC. Thus, in the present study we induced NFC via internal and external time pressure and tested the impact of these manipulations on (...) the performance in tasks that measure executive control, i.e., the Stroop and switching tasks. The results revealed that induced high NFC, indeed boosted performance in executive control tasks. Moreover, there was no difference in the effect of both NFC manipulations on task performance. The implications regarding the role of executive control and specific NFC manipulations in social cognition are discussed. (shrink)
We present a dynamic approach to Peirce’s original construal of abductive logic as a logic of conjecture making, and provide a new decidable, contraction-free and cut-free proof system for the dynamic logic of abductive inferences with neighborhood semantics. Our formulation of the dynamic logic of abduction follows the philosophical and scientific track that led Peirce to his late, post-1903 characterization of abductive conclusions as investigands, namely invitations to investigate propositions conjectured at the level of pre-beliefs.
This study explores the research paradigms of contemporary business ethics research in 2001–2008. With citation data from the top two business ethics journals included in the Social Sciences Citation Index, this study conducts citation and co-citation analysis to identify the most important publications, scholars, and research themes in the business ethics area and then maps the intellectual structure of business ethics studies between 2001 and 2008. The results show that current business ethics studies cluster around four major research themes, including (...) morality and social contract theory, ethical decision making, corporate social responsibility, and stakeholder theory. This study helps profile the invisible network of knowledge production in business ethics and provides important insights on current research paradigms of business ethics studies. (shrink)
