We present a derivation of the homogeneous Lorentz transformations that arrives immediately at the general form without the usual specialization in thex direction.

Executive control of attention refers to processes that detect and resolve conflict among competing thoughts and actions. Despite the high-level nature of this faculty, the role of awareness in executive control of attention is not well understood. In this study, we used interocular suppression to mask the flankers in an arrow flanker task, in which the flankers and the target arrow were presented simultaneously in order to elicit executive control of attention. Participants were unable to detect the flanker arrows or (...) to reliably identify their direction when masked. There was a typical conflict effect (prolonged reaction time and increased error rate under flanker-target incongruent condition compared to congruent condition) when the flanker arrows were unmasked, while the conflict effect was absent when the flanker arrows were masked with interocular suppression. These results suggest that blocking awareness of competing stimuli with interocular suppression prevents the involvement of executive control of attention. (shrink)

As scientific and engineering efforts become increasingly global in nature, the need to understand differences in perceptions of research ethics issues across countries and cultures is imperative. However, investigations into the connection between nationality and ethical decision-making in the sciences have largely generated mixed results. In Study 1 of this paper, a measure of biases and compensatory strategies that could influence ethical decisions was administered. Results from this study indicated that graduate students from the United States and international graduate students (...) studying in the US are prone to different biases. Based on these findings, recommendations are made for developing ethics education interventions to target these decision-making biases. In Study 2, we employed an ethics training intervention based on ethical sensemaking and used a well-established measure of ethical decision-making that more fully captures the content of ethical judgment. Similar to Study 1, the results obtained in this study suggest differences do exist between graduate students from the US and international graduate students in ethical decision-making prior to taking the research ethics training. However, similar effects were observed for both groups following the completion of the ethics training intervention. (shrink)

This essay is a response to the article “Some Foundational Factors for Promoting Human Flourishing.” It offers a broader discussion of flourishing beyond foundational concerns and involves an integration of social science and the humanities.

Guided by principles of life history strategy development, this study tested the hypothesis that sexual precocity and violence are influenced by sensitivities to local environmental conditions. Two models of strategy development were compared: The first is based on indirect perception of ecological cues through family disruption and the second is based on both direct and indirect perception of ecological stressors. Results showed a moderate correlation between rates of violence and sexual precocity (r = 0.59). Although a model incorporating direct and (...) indirect effects provided a better fit than one based on family mediation alone, significant improvements were made by linking some ecological factors directly to behavior independently of strategy development. The models support the contention that violence and teenage pregnancy are part of an ecologically determined pattern of strategy development and suggest that while the family unit is critical in affecting behavior, individuals’ direct experiences of the environment are also important.

"This edited volume explores conceptual and practical challenges in measuring well-being. Given the bewildering array of measures available, and ambiguity regarding when and how to measure particular aspects of well-being, knowledge in the field can be difficult to reconcile. Representing numerous disciplines including psychology, economics, sociology, statistics, public health, theology, and philosophy, contributors consider the philosophical and theological traditions on happiness, well-being and the good life, as well as recent empirical research on well-being and its measurement. Leveraging insights across diverse (...) disciplines, they explore how research can help make sense of the proliferation of different measures and concepts, while also proposing new ideas to advance the field. Some chapters engage with philosophical and theological traditions on happiness, well-being and the good life, some evaluate recent empirical research on well-being and consider how measurement requirements may vary by context and purpose, and others more explicitly integrate methods and synthesize knowledge across disciplines. The final section offers a lively dialogue about a set of recommendations for measuring well-being derived from a consensus of the contributors. Collectively, the chapters provide insight into how scholars might engage beyond disciplinary boundaries and contribute to advances in conceptualizing and measuring well-being. Bringing together work from across often siloed disciplines will provide important insight regarding how people can transcend unhealthy patterns of both individual behavior and social organization in order to pursue the good life and build better societies"--.

Using the corpus of JSTOR articles, we investigate the role of gender in collaboration patterns across the scholarly landscape by analyzing gender-based homophily--the tendency for researchers to co-author with individuals of the same gender. For a nuanced analysis of gender homophily, we develop methodology necessitated by the fact that the data comprises heterogeneous sub-disciplines and that not all authorships are exchangeable. In particular, we distinguish three components of gender homophily in collaborations: a structural component that is due to demographics and (...) non-gendered authorship norms of a scholarly community, a compositional component which is driven by varying gender representation across sub-disciplines, and a behavioral component which we define as the remainder of observed homophily after its structural and compositional components have been taken into account. Using minimal modeling assumptions, we measure and test for behavioral homophily. We find that significant behavioral homophily can be detected across the JSTOR corpus and show that this finding is robust to missing gender indicators in our data. In a secondary analysis, we show that the proportion of female representation in a field is positively associated with significant behavioral homophily. (shrink)

The work described in this report is motivated by the desire to test the expressive possibilities of action language C+. The Causal Calculator (CCalc) is a system that answers queries about action domains described in a fragment of that language. The Zoo World and the Traffic World have been proposed by Erik Sandewall in his Logic Modelling Workshop—an environment for communicating axiomatizations of action domains of nontrivial size. -/- The Zoo World consists of several cages and the exterior, gates between (...) them, and animals of several species, including humans. Actions in this domain include moving within and between cages, opening and closing gates, and mounting and riding animals. The Traffic World includes vehicles moving continuously between road crossings subject to a number of restrictions, such as speed limits and keeping a fixed safety distance away from other vehicles on the road. We show how to represent the two domains in the input language of CCalc, and how to use CCalc to test these representations. (shrink)

Many lymphokine genes have now been cloned from activated T cells and their products have been expressed in mammalian cells. Use of these recombinant lymphokines has provided the opportunity to evaluate both the spectrum of their biological activities and the mechanisms of their action in promoting proliferation and differentiation of hemopoietic and lymphoid cells. Characterization of the structure of lymphokine genes will provide information about their regulated expression in T‐cell activation.

This paper contributes to a broader movement in which the telos of leadership is flourishing, and the primary role of a leader is to promote the flourishing of their team members through creating a loving environment. In support of this, we propose a new perspective on, and associated model, of educational leadership: ‘leadership for teacher flourishing’ (LFTF). This model was developed through a literature review and a mixed methods research project across 78 British schools with collaborative and participatory elements which (...) asked how school leaders could improve the flourishing of teachers. The quantitative and qualitative findings suggested that key factors in enabling teachers to flourish, and therefore incorporated into the model ‘LFTF’, were positive relationships; opportunities for growth; positive impact on subjective wellbeing; and increasing teachers’ sense of meaning at work. The ways leaders could impact these factors were reported as: being supportive and compassionate; being trustworthy; giving teachers autonomy; enabling teachers to grow; being appreciative and focusing on strengths; and enabling teachers to do meaningful work. It was also found that not only leaders could influence flourishing; teachers with no formal leadership role could also positively impact teacher flourishing. It is suggested that virtuous dispositions in leaders are required to ensure they are consistent in acting in ways that promote flourishing. We argue that this integration of virtue and a desire to promote flourishing is properly understood as love. The participatory and collaborative phase of the research showed that teachers wanted autonomy in deciding what would help them to flourish. The conclusion sets out the implications of this research for policy on the training and selection of school leaders, to improve not only the flourishing of teachers, but also pupils and communities.

The endoplasmic reticulum (ER) organelle is the key intracellular site of both protein and lipid biosynthesis. ER dysfunction, termed ER stress, can result in protein accretion within the ER and cell death; a pathophysiological process contributing to a range of metabolic diseases and cancers. ER stress leads to the activation of a protective signalling cascade termed the Unfolded Protein Response (UPR). However, chronic UPR activation can ultimately result in cellular apoptosis. Emerging evidence suggests that cells undergoing ER stress and UPR (...) activation can release extracellular signals that can propagate UPR activation to target tissues in a cell non‐autonomous signalling mechanism. Separately, studies have determined that the UPR plays a key regulatory role in the biosynthesis of bioactive signalling lipids including sphingolipids and ceramides. Here we weigh the evidence to combine these concepts and propose that during ER stress, UPR activation drives the biosynthesis of ceramide lipids, which are exported and function as cell non‐autonomous signals to propagate UPR activation in target cells and tissues.

Business and love appear to have little to do with each other. We hold the opposite to be true if the concept of love in business draws from two corresponding grammars. This paper contributes to the ‘agenda for growth and affirmation of people and the environment’ in business. By focusing on the grammars of love and business we operationalize the concept of love in ways that business executives, managers and employees can understand, adopt, and implement. With references to the theory (...) and practice of management and organizations, we aim to contribute to expanding the theory and practice of responsible organizations and their leaders caring for others.

An ethical and legal framework is needed to regulate the rapidly developing human brain organoid research field properly. However, considering the legal issues involved in human brain organoid research remains underdeveloped and scattered. This article reviews the legal issues of human brain organoid research, grouping them into the following five broad themes: (1) consciousness, (2) legal status, (3) consent, (4) ownership, and (5) transplantation. The issues in each topic include both the urgent (e.g., appropriate forms of consent) and the speculative (...) (e.g., protection of conscious human brain organoids). Therefore, we have attempted to be as explicit as possible about the timescale within which each issue will be realized and to prioritize each. Examining these issues has revealed legal issues specific to human brain organoid research and issues common to research in other fields. Further discussion of human brain organoid research from a legal perspective is needed in the future, considering discussions in related fields. (shrink)

The study examines perceptions of managers, nonmanagerial employees, students, and union officers regarding the legitimacy of managerial influence over various subordinate behaviors and beliefs. The results indicate that: (1) perceived legitimacy has decreased since a comparable study by Schein and Ott in 1962, (2) perceived legitimacy is generally related to proximity to the managerial role, (3) there is a high degree of consensus on the relative legitimacy of influencing various behaviors and beliefs, and (4) only issues of direct relevance to (...) work and task performance are currently perceived as legitimate areas for managerial influence. Theoretical, research, and managerial implications are discussed. (shrink)
