IntroductionCognition generally declines gradually over time due to progressive degeneration of the brain, leading to dementia and eventual loss of independent functions. The rate of regression varies among the six cognitive domains. Current modality of cognitive assessment using neuropsychological paper-and-pencil screening tools for cognitive impairment such as the Montreal Cognitive Assessment has limitations and is influenced by age. Virtual reality is considered as a potential alternative tool to assess cognition. A novel, fully immersive automated VR system has been developed to (...) assess the six cognitive domains. As cognition is associated with age, VR performance is postulated to vary with age using this system.AimsThis is a feasibility study to evaluate the VR performance of cognitively healthy adults aged between 35 and 74 years old, based on the performance score and completion time using the CAVIRE system.MethodsConducted in a public primary care clinic in Singapore, 25 multi-ethnic Asian adults were recruited in each of the four age groups in years: 35–44; 45–54; 55–64, and 65–74. The eligibility criteria included a MoCA score of 26 or higher to reflect normal cognition and understanding English instructions. They completed common daily activities ranging from brushing teething to shopping, across 13 VR segments. Their performances scores and completion time were automatically computed by the CAVIRE system. These VR performance indices were compared across the four age groups using one-way ANOVA, F-test of the hypothesis, followed by pair-wise comparisons in the event of a significant F-test.ResultsOne participant dropped out from Group 1. The demographic characteristics of 99 participants were similar across the 4 age groups. Overall, younger participants in Groups 1 and 2 attained higher VR performance scores and shorter completion time, compared to those in Groups 3 and 4, in all six cognitive domains.ConclusionThe CAVIRE VR performance scores and completion time significantly differ between the younger and older Asian participants with normal cognition. Enhancements to the system are needed to establish the age-group specific normal performance indices. (shrink)

There is little empirical evidence showing a direct link between a capacity for statistical learning (SL) and proficiency with natural language. Moreover, discussion of the role of SL in language acquisition has seldom focused on literacy development. Our study addressed these issues by investigating the relationship between SL and reading ability in typically developing children and healthy adults. We tested SL using visually presented stimuli within a triplet learning paradigm and examined reading ability by administering the Wide Range Achievement Test (...) (WRAT-4; Wilkinson & Robertson, 2006). A total of 38 typically developing children (mean age of 9;5 years, range 6;4–12;5) and 37 healthy adults (mean age of 21 years, range 18–34) were assessed. In children, SL was significantly related to reading ability. Importantly, this relationship was independent of grade and also age. The adult data, too, revealed that SL was significantly related to reading ability. A regression analysis of the combined child and adult data revealed that SL accounted for a unique amount of variance in reading ability, after age and attention had been taken into consideration. For the first time, this study provides empirical evidence that a capacity for more effective SL is related to higher reading ability in the general population. (shrink)

This article clarifies the relationship between moral personhood and moral management in ethical leadership from a Confucian perspective. Drawing from four Confucian classics, this study integrates the leader’s ethical values and activities undertaken to promote virtues in followers. The harmonisation of moral personhood and moral management is facilitated by two cardinal Confucian beliefs: innate human nature and moral self-cultivation. From a Confucian viewpoint, all human beings are endowed with a good nature that enables them to become virtuous persons and leaders. (...) Ethical leaders subdue their selfish desires and extend their natural moral feelings of true goodness, righteousness, propriety and wisdom to others. Moral personhood and moral management are inseparable because to cultivate oneself morally is to help others to become moral persons. By synthesising moral personhood and moral management, a Confucian worldview of ethical leadership contributes to leadership studies in two main ways: safeguarding against the leader’s abuse of power, and advancing organisational change through path-shaping.

Understanding the nature of science has long been a desired outcome of science education, despite ongoing disagreements about the content, structure, and focus of NOS expectations. Addressing the concern that teachers likely focus only on student learning expectations appearing in standards documents, this study examines the current state of NOS in science education standards documents from nine diverse countries to determine the overt NOS learning expectations that appeared, NOS statements provided near those learning expectations, but not identified as learning outcomes, (...) and NOS statements found in ancillary text. Findings indicate that NOS ideas rarely occur as expectations for student learning and are far more commonly found in ancillary material. Moreover, consensus was not apparent in the overt learning outcomes for students. Given the well-documented poor state of NOS instruction and the consistent lack of NOS appearing in published curriculum materials, the NOS standards appearing in nearly all documents analyzed are unlikely to provide sufficient conceptual or pedagogical support for NOS to be accurately interpreted or translated into meaningful experiences for students.

The frontispiece of Hobbes's Leviathan is justly renowned as a powerful visual advertisement for his political philosophy. Consequently, its rich imagery has been the subject of extensive scholarly commentary. Surprisingly, then, its gendered dimensions have received relatively limited attention. This essay explores this neglected facet of the frontispiece. I argue that the image initially appears to present a hypermasculine sovereign. However, upon closer inspection, and considered alongside Hobbes's economic theory, it yields to a reading of the sovereign as an ambiguously (...) gendered figure. Reading the frontispiece through the prism of gender and the economy reveals not a static image of unwavering male power but rather one of an equivocally-sexed creature teeming with life, contradictions, and complexities worthy of continued examination.

The business and human rights movement shares several goals with the Benefit Corporation movement: corporations respecting human rights; maintaining a “wide aperture” so that all impacts of a company on people and communities are addressed; and creating rigorous standards of conduct and means of accountability. This paper argues that nonetheless the movements are traveling along parallel tracks and thus missing an opportunity for mutual learning that can improve their effectiveness. The BHR movement can look to B Corps for concrete examples (...) of viable companies that value human rights intrinsically and not just where there is a “business case” to do so. The B Impact Assessment, the B Corp certification tool, can better ensure that B Corps are in fact respecting human rights by adopting BHR standards. And both movements must give greater consideration to the potential contradiction between unlimited scaling—a key goal of B Corps—and the ability of large multinational corporations to respect human rights.

Many commentators have contrasted the way that sociability is theorized in the writings of Mary Astell and Damaris Masham, emphasizing the extent to which Masham is more interested in embodied, worldly existence. I argue, by contrast, that Astell's own interest in imagining a constitutively relational individual emerges once we pay attention to her use of religious texts and tropes. To explore the relevance of Astell's Christianity, I emphasize both how Astell's Christianity shapes her view of the individual's relation to society (...) and how Masham's contrasting views can be analyzed through the lens of her charge that Astell is an “enthusiast.” In late seventeenth-century England, “enthusiasm” was a term of abuse that, commentators have recently argued, could function polemically to dismiss those deemed either excessively social or antisocial. By accusing Astell of enthusiasm, I claim, Masham seeks to marginalize the relational self that Astell imagines and to promote a more instrumental view of social ties. I suggest some aspects of Astell's thought that may have struck contemporaries as “enthusiastic” and contrast her vision of the self with Masham's more hedonistic subject. I conclude that, although each woman differently configures the relation between self and society, they share a desire to imagine autonomy within a relational framework. (shrink)

In this paper I argue that a greater understanding of the part of ethics in leadership will improve leadership studies. Debates over thedefinition of leadership are really debates over what researchers think constitutes good leadership. The ultimate question is not “What is leadership?” but “What is good leadership?” The word good is refers to both ethics and competence. Research into leadership ethics would explore the ethical issues of current leadership research, serve as a critical study of the field, analyze and (...) expand normative theories of leadership, and develop new theories, research questions and ways of thinking about leadership.

This paper discusses a deterministic model of the spread of an infectious disease in a closed population that was proposed byKermack &McKendrick . The mathematical assumptions on which the model is based are listed and criticized. The ‘threshold theorem’ according to which an epidemic develops if, and only if, the initial population density exceeds a certain value determined by the parameters of the model, is discussed. It is shown that the theorem is not true. A weaker result is stated and (...) proved.A new simplified version of the model is discussed. In this model it is assumed that an infected individual becomes infectious after a constant time and that it will removed after a constant time. Numerical simulations of this model show that the form of the fluctuations in the number of diseased individuals depends on the values of the parameters. The number of infectious individuals may oscillate up and down under certain circumstances. Necessary conditions for the number of infectious individuals to rise above previous levels are stated and proved. (shrink)

This study examines how authentic leadership influences team performance via the mediating mechanism of team reflexivity. Adopting a self-regulatory perspective, we propose that authentic leadership will predict the specific team regulatory process of reflexivity, which in turn will be associated with two outcomes of team performance, effectiveness and productivity. Using survey data from 53 teams in three organizations in the United Kingdom and Greece and controlling for collective trust, we found support for our stated hypotheses with the results indicating a (...) significant fully mediated relationship. As predicted the self-regulatory behaviors inherent in the process of authentic leadership served to collectively shape team behavior, manifesting in the process of team reflexivity, which, in turn, positively predicted team performance. We conclude with a discussion of how this study extends theoretical understanding of authentic leadership in relation to teamwork and delineate several practical implications for leaders and organizations.

The University of Pittsburgh Medical Center (UPMC) "Policy for the Management of Terminally Ill Patients Who May Become Organ Donors after Death" proposes to take organs from certain patients as soon as possible after expected cardiopulmonary death. This policy requires clear understanding of the descriptive state of the donor's critical cardiopulmonary and neurologic functional capacity at the time interventions to sustain or harvest organs are undertaken. It also requires strong consensus about the moral and legal status of the donor during (...) dying and confirmation of death. There has been no need for the clarity and precision that this policy relies upon, and thus the needed research and conceptual work has not previously been generated. The empiric base and societal consensus are both too frail to provide justification for this policy at this time. (shrink)

In today's business world, ethics is not simply a peripheral concern of executive boards or a set of supposed constraints on free enterprise. Ethics stands at the very core of our working lives and of society as a whole, defining the public image of the business community and the ways in which individual companies and people behave. What people do at work--and how they think about work--determines their attitudes and aspirations, affecting and even structuring their personal lives and habits. Working (...) from this premise, Honest Work: A Business Ethics Reader provides a practical overview of business ethics that concentrates on the ethical problems and dilemmas students are most likely to face in their prospective work environments. Classic and recent articles and cases cover a broad spectrum of issues and concerns--from private ethical dilemmas to larger considerations of corporate values--and propose guidelines for thinking about the business world in a moral context. Each reading and case is followed by lively questions for discussion. Offering a welcome alternative to the impersonal tone of most business ethics texts, the editors address students in an appealing and conversational manner. They provide engaging chapter introductions that include personal narratives and also present the ideas of great philosophers in a unique way--as emails. Ideal for introductory undergraduate and MBA courses in business ethics, Honest Work: A Business Ethics Reader can be read as a coherent narrative but also offers instructors great flexibility, as its various chapters, readings, and cases can be pursued in almost any order. A Companion Website featuring chapter objectives and summaries, study questions, self-tests, and off-site links of interest will soon be available. An Instructor's Manual with Test Bank is available to adopters. (shrink)

Advances in science have led to a new vision for toxicity testing based on human cell systems that will be more predictive, have higher throughput, cost less money, and be more comparable to real‐life exposures in humans, while using many fewer animals. This vision, embraced by leading scientific and regulatory groups, is a paradigm shift from animal‐based to human‐based testing that signals a major change in focus and promotes the development of new approaches to understanding the toxicity of chemicals in (...) humans. Information gained from these new approaches will likely affect other areas of research as well, leading to less reliance on animals in the future. (shrink)

Environmental journalism has been criticized by various special interest groups and some editors for advocacy and faulted for inaccuracies. Sources, in turn, many from the science communities, have been accused of inaccessibility, and public relations representatiws from both industry and environmental organizations are regularly blamed for unethical behaviors rangingfrom hyperbole to more serious discussion or omission of factual information. This article reports a preliminary study of ethical decision making among members of the Society of Environmental Journalists, identifying ethical motivation diljerences (...) using the Ethical Motivation Scale. The implications of the reported dominant extrinsic guides are discussed in light of a proposed protocol for ethical environmental communication. (shrink)

BackgroundFear of cancer recurrence is common amongst cancer survivors. There is rapidly growing research interest in FCR but a need to prioritize research to address the most pressing clinical issues and reduce duplication and fragmentation of effort. This study aimed to establish international consensus among clinical and academic FCR experts regarding priorities for FCR research.MethodsMembers of the International Psycho-oncology Society Fear of Cancer Recurrence Special Interest Group were invited to participate in an online Delphi study. Research domains identified in Round (...) 1 were presented and discussed at a focus group to consolidate the domains and items prior to presentation in further survey rounds aimed at gaining consensus on research priorities of international significance.ResultsThirty four research items were identified in Round 1 and 33 of the items were consolidated into six overarching themes through a focus group discussion with FCR experts. The 33 research items were presented in subsequent rounds of the delphi technique. Twenty one participants contributed to delphi round 1, 16 in round 2, and 25 and 29 participants for subsequent delphi rounds. Consensus was reached for 27 items in round 3.1. A further four research items were identified by panelists and included in round 3.2. After round 3.2, 35 individual research items were ratified by the panelists. Given the high levels of consensus and stability between rounds, no further rounds were conducted. Overall intervention research was considered the most important focus for FCR research. Panelists identified models of care that facilitate greater access to FCR treatment and evaluation of the effectiveness of FCR interventions in real world settings as the two research items of highest priority. Defining the mechanisms of action and active components across FCR/P interventions was the third highest priority identified.ConclusionThe findings of this study outline a research agenda for international FCR research. Intervention research to identify models of care that increase access to treatment are based on a flexible approach based on symptom severity and can be delivered within routine clinical care were identified as research areas to prioritize. Greater understanding of the active components and mechanisms of action of existing FCR interventions will facilitate increased tailoring of interventions to meet patient need. (shrink)
