We study a generalization of the standard syntax and game-theoretic semantics of logic, which is based on a duality between two players, to a multiplayer setting. We define propositional and modal languages of multiplayer formulas, and provide them with a semantics involving a multiplayer game. Our focus is on the notion of equivalence between two formulas, which is defined by saying that two formulas are equivalent if under each valuation, the set of players with a winning strategy is the same (...) in the two respective associated games. We provide a derivation system which enumerates the pairs of equivalent formulas, both in the propositional case and in the modal case. Our approach is algebraic: We introduce multiplayer algebras as the analogue of Boolean algebras, and show, as the corresponding analog to Stone’s theorem, that these abstract multiplayer algebras can be represented as concrete ones which capture the game-theoretic semantics. For the modal case we prove a similar result. We also address the computational complexity of the problem whether two given multiplayer formulas are equivalent. In the propositional case, we show that this problem is co-NP-complete, whereas in the modal case, it is PSPACE-hard. (shrink)

This article provides a brief overview of several formal frameworks concerning the relation between knowledge on the one hand, and obligation on the other. We discuss the paradox of the knower, knowledge based obligation, knowingly doing, deontic dynamic epistemology, descriptive obligations, and responsibilities as dynamic epistemology.

Background: The division of non-paid labor in heterosexual parents in the West is usually still gender-based, with mothers taking on the majority of direct caregiving responsibilities. However, in same-sex couples, gender cannot be the deciding factor. Inspired by Feinberg’s ecological model of co-parenting, this study investigated whether infant temperament, parent factors (biological relatedness to child, psychological adjustment, parenting stress, and work status), and partner relationship quality explained how first-time gay, lesbian, and heterosexual parents divided labor (childcare and family decision-making) when (...) their infants were four months and 12 months old. We also tested whether family type acted as a moderator. Method: Participants were drawn from [MASKED FOR REVIEW]. Only those who provided information about their biological relatedness (yes or no) to their child (N = 263 parents) were included. When infants were four months (T1), parents completed a password-protected online questionnaire exploring their demographic characteristics including work status and standardized online-questionnaires on task division (childcare and family decision-making), infant temperament, parental anxiety, parental depression, parental stress, and partner relationship satisfaction. When infants were 12-months-old (T2), parents provided information about task division and their biological relatedness to their children. Results: Linear mixed models showed that no factor explained the division of family decision making at T1 and T2. For relative time spent on childcare tasks at T1, biological relatedness mattered for lesbian mothers only: biologically related mothers appeared to spend more time on childcare tasks than did non-related mothers. Results showed that, regardless of family type, parents who were not working or were working part-time at T1 performed more childcare tasks at T1. This was still true at T2. The other factors did not significantly contribute to relative time spent on childcare tasks at T2. Conclusion: We had the opportunity to analyze the division of non-paid tasks in families where parenting was necessarily planned and in which gender could not affect that division. Although Feinberg’s model of co-parenting suggests that various factors are related to task division, we found that paid work outside the home was most important during the first year of parenthood in determining caregiving roles.

…vel quod res omnes timide gelideque ministrat, dilator, † spe longus, iners avidusque futuri, diffcilis, querulus… I agree with Brink, and other editors referred to by him ad loe, that spe longus in Horace's description of the typical old man's character cannot be made to give sense. For earlier attempts at emendation, see Brink's note . Most of those who have tried to emend the passage concentrate on longus, and are reluctant to relinquish spe: this is largely due to the (...) parallel with Aristotle's account of the character of old men in Rhetoric 2. 13. 1389b 13ff., in which they are said to be, among other things it seems to me that this parallel should not be pressed too far. There is much in Aristotle that is not in Horace, and nothing to suggest close and detailed dependence. The parallel can only be relevant if spe longus can be turned into a reasonable Latin equivalent for Otherwise there is no good reason to suppose that spe is any less likely to be corrupt than longus.

Medical and public health research includes surveys, interviews, and biospecimens — techniques that do not present substantial risks to subjects. Consequently, this research is exempt from regulation under the Federal Common Rule. Nevertheless, at many institutions, exempt research is frequently subject to the same regulatory process that is required for non-exempt research, requiring the consumption of time and resources for review by Institutional Review Board members or staff. The federal government has indicated an intention to reform and centralize this system, (...) but has not yet specified the form that it will use instead. By examining the policies of the top 50 research institutions, this article assesses institutional practices surrounding exempt research, quantifies the extent of exempt-research review requirements, documents a problem of “over-compliance,” and makes recommendations for reform.

_Background and aims:_ Intensive mothering norms prescribe women to be perfect mothers. Recent research has shown that women’s experiences of pressure toward perfect parenting are related to higher levels of guilt and stress. The current paper follows up on this research with two aims: First, we examine how mothers regulate pressure toward perfect mothering affectively, cognitively, and behaviorally, and how such regulation may relate to parental burnout. Second, we examine how feeling pressure toward perfect mothering may spill over into mothers’ (...) work outcomes. _Methods:_ Through Prolific Academic, an online survey was sent to fulltime working mothers in the United Kingdom and United States with at least one child living at home ( N = 169). Data were analyzed using bootstrapping mediation models. _Results:_ Feeling pressure to be a perfect mother was positively related to parental burnout, and this relation was mediated by parental stress, by a stronger cognitive prevention focus aimed at avoiding mistakes as a mother, and by higher maternal gatekeeping behaviors taking over family tasks from one’s partner. Moreover, pressure toward perfect mothering had a positive direct effect on career ambitions; and a negative indirect effect, such that mothers with higher felt pressure toward perfect mothering experienced lower work-family balance, which in turn related to lower career ambitions. _Conclusion:_ The findings suggest that intensive mothering norms might have severe costs for women’s family and work outcomes, and provide insights into where to direct efforts to reduce motherhood hardships and protect women’s career ambitions.

Over the past three or four decades, the concept of medical ethics has changed from a limited set of standards to a broad field of debate and research. We define medical ethics as an arena of moral issues in medicine, rather than a specific discipline. This paper examines how the disciplines of health care ethics and health care law have developed and operated within this arena. Our framework highlights the aspects of jurisdiction and the assignment of responsibilities . This theoretical (...) framework prompted us to study definitions and changing responsibilities in order to describe the development and interaction of health care ethics and health law. We have opted for the context of the Dutch debate about end-of-life decisions as a relevant case study. We argue that the specific Dutch definition of euthanasia as ‘intentionally taking the life of another person by a physician, upon that person’s request’ can be seen as the result of the complex jurisdictional process. This illustrates the more general conclusion that the Dutch debate on end-of-life decisions and the development of the two disciplines must be understood in terms of mutual interaction. (shrink)

This essay traces the history of premenstrual syndrome in French, British, and American medical literature from 1950 to 2004. Aetiological theories, treatments and diagnostic criteria have varied over time and place, reflecting local conditions and changing notions of objectivity and evidence. During the 1970s researchers in each nation utilised different research strategies to overcome variation and contradictory results characteristic of PMS research. Since the 1980s, attempts have been made to standardise research internationally through prospective daily rating questionnaires that diagnose and (...) measure PMS. Amidst controversy, a psychiatric reformulation of the syndrome was included in the Diagnostic and Statistical Manual of Mental Disorders . While the diagnostic criteria for this psychiatric category, now called premenstrual dysphoric disorder , are widely accepted for research purposes, efforts to transfer them to medical practice have been less successful. PMDD remains a contested disease construct. (shrink)

This article is a case study of a woman-owned and-operated sexual products business, conceived in the midst of a fragmenting women's movement in 1977. The article tracks the evolution of pro-sex feminist ideology within this business during the past 22 years. Whereas most feminist organizations research focuses on nonprofit organizations and their relationship to the state, this study focuses on a political organization that depends on profits for survival. The voices in this study reveal the complexities of running an “alternative” (...) business during the 1980s and 1990s and of balancing political ideals with profit needs. Ironically, as Toy Box and its consumer base grow, more and more men and women are exposed to pro-sex feminism and buying into its philosophy. This contradiction is fundamental to the story of Toy Box's history and evolution. (shrink)

The nature of mental representations of linguistic expressions in relation to the time course from intention to articulation is a major issue. We discuss Branigan & Pickering's proposal to use structural priming to tap into this process. We show that their interpretation of their findings cannot be maintained. We reinterpret these results and suggest a revision of their conclusions.

This article focuses on the influence of male role models on the lives of adolescents in the U.S. National Longitudinal Lesbian Family Study. Half of the adolescents had male role models; those with and those without male role models had similar scores on the feminine and masculine scales of the Bem Sex Role Inventory, as well as on the trait subscales of the State-Trait Personality Inventory and the Child Behavior Checklist. A positive association was found between feminine gender role traits (...) and curiosity, and a negative correlation between this trait and internalizing problem behavior; these associations were independent of the gender of the adolescents and the presence of male role models. In sum, the absence of male role models did not adversely affect the psychological adjustment of adolescents reared by lesbian mothers. (shrink)

We present nine facets for the analysis of the past and future evolution of AI. Each facet has also a set of edges that can summarise different trends and contours in AI. With them, we first conduct a quantitative analysis using the information from two decades of AAAI/IJCAI conferences and around 50 years of documents from AI topics, an official database from the AAAI, illustrated by several plots. We then perform a qualitative analysis using the facets and edges, locating AI (...) systems in the intelligence landscape and the discipline as a whole. This analytical framework provides a more structured and systematic way of looking at the shape and boundaries of AI. (shrink)

Despite changes in their representation and visibility, there are still serious concerns about the inclusion and day-to-day workplace challenges various groups face (e.g., women, ethnic and cultural minorities, LGBTQ+, people as they age, and those dealing with physical or mental disabilities). Men are also underrepresented in specific work fields, in particular those in HEED (Health care, Elementary Education and the Domestic sphere). Previous literature has shown that group stereotypes play an important role in maintaining these inequalities. We outline how insights (...) from research on stigma, social-identity, and self-regulation together increase our understanding of how targets are affected by and regulate negative stereotypes in the workplace. This approach starts from the basis that members of negatively-stereotyped groups are not just passive recipients of negative attitudes, stereotypes, and behaviors, but are active individuals pursuing multiple goals, such as goals for belonging and achievement. We argue that it is only by understanding stigma from the target’s perspective (e.g., how targets are affected and respond) that we can successfully address workplace inequality. Key in this understanding is that stereotypes, prejudice and discrimination have taken on much more subtle forms, with consequences for the way members of stigmatized-groups cope. These insights lead us to propose an approach to understanding barriers to workplace equality that highlights four key aspects: a) the different (often subtle) potential triggers of identity-threat in the workplace for members of stigmatized-groups, b) the ways in which members of stigmatized-groups cope with these threats, c) the role of supportive factors that mitigate potential threats and affect self-regulation, and d) potential hidden costs for the self or others of what appears at first to be effective self-regulation. The focus on threats, coping, support, and potential hidden costs helps us understand why current diversity efforts are not always successful in increasing and maintaining members of stigmatized-groups in organizations, and provides insight into how we can aid efforts to effectively lower barriers to workplace equality.

Codes of ethics exist in many, if not the majority, of all large U.S. companies today. But how the impact of these written codes affect managerial attitudes and behavior is still not clearly documented or explained. This study takes a step in that direction by proposing that attention should shift from the codes themselves as the sources of ethical behavior to the persons whose behavior is the focus of these codes. In particular, this study investigates the role of code familiarity (...) as a factor impacting the influence of an ethics code on manager behavior. Data collected from 286 executives from companies in the direct selling industry are used to test hypotheses (1) that the perceived usefulness of ethics codes is positively related to the degree of familiarity with the code, and (2) that ethical climate as assessed by managers is positively related to the code''s perceived usefulness. Both hypotheses are supported, and their implications and further research directions are discussed. (shrink)

This essay traces the roots of corporate social responsibility in Norway. It is argued that a basic tenet of CSR, an orientation toward the concerns of stakeholders, has a long history in Norwegian business, predating the modern CSR movement. The essay underscores certain qualities of the Norwegian business system and the Norwegian political culture in order to explain how this stakeholder orientation grew and how CSR is perceived and practiced today. Corporatism and dialog are traits which position Norwegian businesses well (...) to address CSR in a globalized economy. Present-day examples of companies and practices are provided to illustrate key features of Norwegian CSR, as it has developed over the course of more than 150 years. (shrink)

Despite acknowledgment that performance failure among new salespeople is a prevalent issue for organizations, researchers do not fully understand the consequences of repetitive periods of failure on new salespeople’s unethical selling behaviors. Further, little is known about how a sales force’s reward structure and managerial attempts to intervene following failure affect new salespeople’s behavior. Combining an experiment with longitudinal growth models, we show that repetitive periods of failure increase unethical behaviors, and interventions intended to remind the salesperson to behave in (...) the customer’s best interests attenuate this effect under a non-contingent reward structure. However, counter to managerial assumptions, under a contingent reward structure these customer-oriented interventions actually backfire by amplifying the original relationship between repetitive failure and unethical behaviors. The results have potentially important managerial implications for those who manage new salespeople learning how to sell or during other failure-prone periods. (shrink)

By asking how well theological views of human nature stand up to the discoveries of modern science, Alan Olding re-opens the question of whether the "design" argument for the existence of God is fatally undermined. A distinctive feature of the work is its emphasis on the metaphysical implications of biology and how these at times conflict with other, more plausible metaphysical positions. Another is its close critical examination of the "design" argument and of the relation God has to the world (...) he creates. "Modern Biology and Natural Theology" takes up issues currently of concern to many thinkers and will provide fascinating reading for anyone interested in philosophical problems, particularly the impact of Darwinism on natural theology.
