A variety of non-human females do not select male partners independently. Instead they favor males having previous associations with other females, a phenomenon known as mate copying. This paper investigates whether humans also exhibit mate copying and whether consistent positive information about a man’s mate value, and a woman’s age and self-perceived mate value (SPMV), influence her tendency to copy the mate choices of others. Female university students (N = 123) rated the desirability of photographed men pictured alone or with (...) one, two, or five women represented by silhouettes. In accordance with the visual arrays, men were described as currently in a romantic relationship; having previously been in one, two, or five relationships; or not having had a romantic relationship in the past 4 years. Women generally rated men pictured with one or two previous partners as more desirable than those with none. Men depicted with five previous partners, however, were found to be less desirable. Younger, presumably less experienced women had a greater tendency to mate copy compared with older women, but high SPMV did not predict greater levels of mate copying. The findings reaffirmed and expanded those suggesting that women do not make mate choices independently. (shrink)

Imperial Plato presents new translations of three introductions to Plato's thought from the second half of the second century CE: the Introduction to Plato by Albinus of Smyrna, Dissertation 11 of Maximus of Tyre, and On Plato and his Teaching by Apuleius of Madaurus. These three presentations of Plato's ideas--one a Greek dialectic introduction with a suggested reading order for Plato's dialogues, another a Greek speech in the sophistic style of the time, and one a lengthy doxological study in Latin--are (...) examples by three distinct authors using divergent methods of the assorted ways in which Plato and Platonism were understood and discussed during the revival of Hellenism and Greek Philosophy, and the period of the Roman Empire often referred to as the Second Sophistic.

In the last decade the use of advance directives or living wills has become increasingly common. This paper is concerned with those advance directives in which the user opts for withdrawal of active treatment in a future situation where he or she is incompetent to consent to conservative management but where that incompetence is potentially reversible. This type of directive assumes that the individual is able accurately to determine the type of treatment he or she would have adopted had he (...) or she been competent in this future scenario. The paper argues that this assumption is flawed and provides theoretical and empirical evidence for this. If the assumption is false, and those taking out advance directives do not realise this, then the ethical bases for the use of these advance directives-the maximisation of the individual's autonomy and minimisation of harm-are undermined. The paper concludes that this form of advance directive should be abolished. (shrink)

This paper provides an empirically informed perspective on the notion of responsibility using an ethical framework that has received little attention in the engineering-related literature to date: ethics of care. In this work, we ground conceptual explorations of engineering responsibility in empirical findings from engineering student’s writing on the human health and environmental impacts of “backyard” electronic waste recycling/disposal. Our findings, from a purposefully diverse sample of engineering students in an introductory electrical engineering course, indicate that most of these engineers (...) of tomorrow associated engineers with responsibility for the electronic waste problem in some way. However, a number of responses suggested attempts to deflect responsibility away from engineers towards, for example, the government or the companies for whom engineers work. Still other students associated both engineers and non-engineers with responsibility, demonstrating the distributed/collective nature of responsibility that will be required to achieve a solution to the global problem of excessive e-waste. Building upon one element of a framework for care ethics adopted from the wider literature, these empirical findings are used to facilitate a preliminary, conceptual exploration of care-ethical responsibility within the context of engineering and e-waste recycling/disposal. The objective of this exploration is to provide a first step toward understanding how care-ethical responsibility applies to engineering. We also hope to seed dialogue within the engineering community about its ethical responsibilities on the issue. We conclude the paper with a discussion of its implications for engineering education and engineering ethics that suggests changes for educational policy and the practice of engineering. (shrink)

For Levinas dialogue occurs when one is open to and receptive of the Other. He cautions, however, that although dialogue impedes violence, it should not be pursued unilaterally or vigorously, because this can also lead to violence. The abolition of violence, which is the goal at which dialogue aims, can instead turn violent in the face of unrestrained persuasive discourse. Vigilance and caution must be maintained if dialogue is not to lapse into hostility and aggression. It is important to respect (...) differences and acknowledge insoluble problems in order to avoid animosity. Without recognition and respect, dialogue can become adversarial and antagonistic.

Ethical issues arising from public administration are quite complex and difficult. Using a monistic normative ethical approach to these issues may not be very helpful. Thus James Svara’s three-pronged approach to public administration ethics is proposed in order to show its plausibility. The case of Dr Stockman in Henrik Ibsen’s play An Enemy of the People is examined as a way of demonstrating the significance of Svara’s model.

The author applies the definitions of surrogacy offered by Donum vitae to the question of embryo adoption and shows that embryo adoption does not in fact constitute an act of surrogacy. The author shows that neither Donum vitae nor Dignitas personae condemns heterologous embryo transfer or embryo adoption per se but only when these acts also involve illicit forms of artificial fertilization or surrogacy. The author suggests that the apparent reason for a lack of endorsement of embryo adoption by Donum (...) vitae and Dignitas personae is pastoral caution, concern for scandal, and the connection between embryo adoption and IVF; it is not because embryo adoption is intrinsically illicit.

Body integrity identity disorder is a very rare condition in which people experience long-standing anguish because there is a mismatch between their bodies and their internal image of how their bodies should be. Most typically, these people are deeply distressed by the presence of what they openly acknowledge as a perfectly normal leg. Some with the condition request that their limb be amputated. 1 We and others have argued that such requests should be acceded to in carefully selected patients.1–4 Consistent (...) with this view, a group at the University of Sydney is developing a programme to better understand and treat BIID and to offer amputation if appropriate. In a recent paper, Patrone argues that such amputations should be prohibited.5 He suggests that authors supporting amputation in BIID depend on analogies with more familiar conditions and then claim that the ‘the desires, choices and requests of BIID patients should be held to exactly the same standards and treated with exactly the same respect as the desires, choices and requests of any more conventional patient’.5 He believes that these analogies are invalid and that therefore the arguments for amputation are invalid.Patrone concentrates a great deal upon whether a decision to have a particular medical intervention is to be regarded as ‘rational’. Unfortunately, he makes no attempt to define what he …. (shrink)

Is there ever any reason for a doctor to lie to a patient? In this paper, we critically review the literature on lying to patients and challenge the common notion that while lying is unacceptable, a related entity--'benevolent deception' is defensible. Further, we outline a rare circumstance when treating psychotic patients where lying to the patient is justified. This circumstance is illustrated by a clinical vignette.

Objectives: The mental health legislation of most developed countries includes either a dangerousness criterion or an obligatory dangerousness criterion (ODC). A dangerousness criterion holds that mentally ill people may be given treatment without consent if they are deemed to be a risk to themselves or others. An ODC holds that mentally ill people may be given treatment without consent only if they are deemed to be a risk to themselves or others. This paper argues that the dangerousness criterion is unnecessary, (...) unethical and, in the case of the ODC, potentially harmful to mentally ill people and to the rest of the community. Methods: We examine the history of the dangerousness criterion, and provide reasoned argument and empirical evidence in support of our position. Results: Dangerousness criteria are not required to balance the perceived loss of autonomy arising from mental health legislation. Dangerousness criteria unfairly discriminate against the mentally ill, as they represent an unreasonable barrier to treatment without consent, and they spread the burden of risk that any mentally ill person might become violent across large numbers of mentally ill people who will never become violent. Mental health legislation that includes an ODC is associated with a longer duration of untreated psychosis, and probably contributes to a poorer prognosis and an increase risk of suicide and violence in patients in their first episode of psychosis. Conclusions: Dangerousness criteria should be removed from mental health legislation and be replaced by criteria that focus on a patient’s capacity to refuse treatment. (shrink)

The slippery slope argument has been the mainstay of many of those opposed to the legalisation of physician-assisted suicide and euthanasia. In this paper I re-examine the slippery slope in the light of two recent studies that examined the prevalence of medical decisions concerning the end of life in the Netherlands and in Australia. I argue that these two studies have robbed the slippery slope of the source of its power--its intuitive obviousness. Finally I propose that, contrary to the warnings (...) of the slippery slope, the available evidence suggests that the legalisation of physician-assisted suicide might actually decrease the prevalence of non-voluntary and involuntary euthanasia.

A crisis continues to brew within the pharmaceutical research and development (R&D) enterprise: productivity continues declining as costs rise, despite ongoing, often dramatic scientific and technical advances. To reverse this trend, we offer various suggestions for both the expansion and broader adoption of modeling and simulation (M&S) methods. We suggest strategies and scenarios intended to enable new M&S use cases that directly engage R&D knowledge generation and build actionable mechanistic insight, thereby opening the door to enhanced productivity. What M&S requirements (...) must be satisfied to access and open the door, and begin reversing the productivity decline? Can current methods and tools fulfill the requirements, or are new methods necessary? We draw on the relevant, recent literature to provide and explore answers. In so doing, we identify essential, key roles for agent-based and other methods. We assemble a list of requirements necessary for M&S to meet the diverse needs distilled from a collection of research, review, and opinion articles. We argue that to realize its full potential, M&S should be actualized within a larger information technology framework—a dynamic knowledge repository—wherein models of various types execute, evolve, and increase in accuracy over time. We offer some details of the issues that must be addressed for such a repository to accrue the capabilities needed to reverse the productivity decline. (shrink)

The Cambridge Handbook of the Global Work-Family Interface is a response to growing interest in understanding how people manage their work and family lives across the globe. Given global and regional differences in cultural values, economies, and policies and practices, research on work-family management is not always easily transportable to different contexts. Researchers have begun to acknowledge this, conducting research in various national settings, but the literature lacks a comprehensive source that aims to synthesize the state of knowledge, theoretical progression, (...) and identification of the most compelling future research ideas within field. The Cambridge Handbook of the Global Work-Family Interface aims to fill this gap by providing a single source where readers can find not only information about the general state of global work-family research, but also comprehensive reviews of region-specific research. It will be of value to researchers, graduate students, and practitioners of applied and organizational psychology, management, and family studies. (shrink)

Trafficking and persistence of fetal microchimeric cells (fMCs) and circulating extracellular vesicles (EVs) have been observed in animals and humans, but their consequences in the maternal body and their mechanistic contributions to maternal physiology and pathophysiology are not yet fully defined. Fetal cells and EVs may help remodel maternal organs after pregnancy‐associated changes, but the cell types and EV cargos reaching the mother in preterm pregnancies after exposure to various risk factors can be distinct from term pregnancies. As preterm delivery‐associated (...) maternal complications are rising, revisiting this topic and formulating scientific questions for future research to reduce the risk of maternal morbidities are timely. Epidemiological studies report maternal cardiovascular risk as one of the major complications after preterm delivery. This paper suggests a potential link between fMCs and circulating EVs and adverse maternal cardiovascular outcomes post‐pregnancies, the underlying mechanisms, consequences, and methods for and how this link might be assessed.

Due to natural selection pressure, certain aspects of memory may have been selected to give humans a survival advantage. Research has demonstrated that processing information for survival relevance leads to better item memory (i.e., the content of information) compared to control conditions. The current study investigates the effects of survival processing on context memory (i.e., memory for peripheral episodic details) and item memory to better understand when the survival processing memory advantage emerges. In this study, participants viewed objects in either (...) a plausible color, for example a red apple, or in an implausible color, such as a green pie. We chose this color plausibility manipulation because color is a detail that conveys information about the fitness of an item. After studying items in either a survival or moving (control) condition, participants made item memory judgments (did you see this item before?), and two context memory judgments: color context (in which color did you see this item?), and source context (in which condition did you see this item?). Results indicated better item memory for materials processed in the survival relative to moving condition. Critically, for color context there was a condition by plausibility interaction, where memory was best for plausibly colored items in the survival processing condition. There was no difference, however, in source context memory between the survival and moving conditions. These results suggest the survival processing memory advantage extends to some contextual details, but only those details that tap into the survival utility of items, such as color. (shrink)

The co-occurrence of stress-induced posttraumatic stress disorder (PTSD) and obesity is common, particularly among military personnel but the link between these conditions is unclear. Individuals with comorbid PTSD and obesity manifest other physical and psychological problems, which significantly diminish their quality of life. Current understanding of the pathways connecting stress to PTSD and obesity is focused largely on behavioral mediators alone with little consideration of the biological regulatory mechanisms that underlie their co-occurrence. In this work, we leverage prior knowledge to (...) systematically highlight such bio-behavioral mechanisms and inform on the design of confirmatory pilot studies. We use natural language processing (NLP) to extract documented regulatory interactions involved in the metabolic response to stress and its impact on obesity and PTSD from over 8 million peer-reviewed papers. The resulting network describes the propagation of stress to PTSD and obesity through 34 metabolic mediators using 302 documented regulatory interactions supported by over 10,000 citations. Stress jointly affected both conditions through 21 distinct pathways involving only two intermediate metabolic mediators out of a total of 76 available paths through this network. Moreover, oxytocin (OXT), Neuropeptide-Y (NPY), and cortisol supported an almost direct propagation of stress to PTSD and obesity with different net effects. Although stress upregulated both NPY and cortisol, the downstream effects of both markers are reported to relieve PTSD severity but exacerbate obesity. The stress-mediated release of oxytocin, however, was found to concurrently downregulate the severity of both conditions. These findings highlight how a network-informed approach that leverages prior knowledge might be used effectively in identifying key mediators like OXT though experimental verification of signal transmission dynamics through each path will be needed to determine the actual likelihood and extent of each marker’s participation.

Using a longitudinal case study design, we have tracked the recovery of motor function following severe traumatic brain injury (TBI) through a multimodal neuroimaging approach. In 2006, Canadian Soldier Captain (retired) Trevor Greene (TG) was attacked with an axe to the head while on tour in Afghanistan. TG continues intensive daily rehabilitation, which recently included the integration of physical therapy (PT) with neuromodulation using translingual neurostimulation (TLNS) to facilitate neuroplasticity. Recent findings with PT+TLNS demonstrated that recovery of motor function occurred (...) beyond conventional time limits, currently extending past 14-years post-injury. To investigate whether PT+TLNS similarly resulted in associated cognitive function improvements, we examined event-related potentials (ERPs) with the brain vital signs framework. In parallel with motor function improvements, brain vital signs detected significant increases in basic attention (as measured by P300 response amplitude) and cognitive processing (as measured by contextual N400 response amplitude). These objective cognitive improvements corresponded with TG’s self-reported improvements, including a noteworthy and consistent reduction in ongoing symptoms of post-traumatic stress disorder (PTSD). The findings provide valuable insight into the potential importance of non-invasive neuromodulation in cognitive rehabilitation, in addition to initial indications for physical rehabilitation.

How does anthoethnography contribute to the development of understandings of aesthetic experiences of wild plants and wildflower tourism? As exemplified by the quintessentially aesthetic industry of wildflower tourism, the culture of flora represents diverse engagements between people and plants. Such complex engagements offer further avenues for research. The critical methodology of anthoethnography has been one such approach to circumscribing the values, practices and rhetoric of wildflower tourism. Interviews have revealed perceptual phenomena such as the orchid and everlasting effects as two (...) counterpoised examples of the differences between visual aesthetic values occurring in the region. For appreciators such as Tinker, botanical science substantiates visual experience by showing the functional role of plants within habitats. However, the taxonomic eye is not the only judge of the value and significance of flowering plants. As underscored by Nannup, Aboriginal perspectives offer complex cultural modes of engagement and rich directions for wildflower tourism based in bodily experience. An anthoethnographic approach produces accounts of the spectrum of human perceptions of wildflowers in order to proffer potential directions for wildflower tourism of the future. Through a participatory aesthetics of flora in contemporary Australian landscapes, appreciative interactions with plants will occur not only through visual values, but also through the smell, taste, sound, or feel of plants and how one moves through communities of flora. Scientific knowledge can amplify visual and embodied modes. However, as an anthoethnographic lens has shown, wildflower tourism in the Southwest is weighted towards visual experience. Indeed, the history and contemporary practices of wildflower tourism encode ocular values that can posit a separation between post‐colonial cultures and native flora. A promising direction is towards participatory relationships beyond the aestheticisation of the surface qualities of flora and beyond the ‘conquest of the world as picture’. In an era of rapid species loss, wildflower tourism will increasingly embrace concepts of conservation, Aboriginal knowledges and the recognition of spiritual heritages, and the appreciation of plants beyond their visual impact. The expression of human sensory capacities for plants joined to an ethos of botanical conservation, drawing from scientific thought, can better ensure the longevity of flowers through the evolution of the culture of flora in the region.

From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in (...) the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting “culpable” limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of “forgivably” limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious – but doxastically1noncommittal – action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, onlypositive illusionsmeet our criteria. (shrink)

Neurological diseases, particularly in the context of aging, have serious impacts on quality of life and can negatively affect bone health. The brain-bone axis is critically important for skeletal metabolism, sensory innervation, and endocrine cross-talk between these organs. This review discusses current evidence for the cellular and molecular mechanisms by which various neurological disease categories, including autoimmune, developmental, dementia-related, movement, neuromuscular, stroke, trauma, and psychological, impart changes in bone homeostasis and mass, as well as fracture risk. Likewise, how bone may (...) affect neurological function is discussed. Gaining a better understanding of brain-bone interactions, particularly in patients with underlying neurological disorders, may lead to development of novel therapies and discovery of shared risk factors, as well as highlight the need for broad, whole-health clinical approaches toward treatment.

Stephen Evans, we argue that Thomas Reid’s notion of “natural signs” helpfully illuminates how people can perceive God indirectly through natural beauty. First, we explain how some natural signs enable what Alston labels “indirect perception.” Second, we explore how certain emotions make it possible to see both beauty and the excellence of the minds behind beauty. Finally, (...) we explain how aesthetic emotions can involve indirect perception of God via the natural sign of natural beauty. (shrink)

While the concept of work ethic has been discussed in the Arab context :35–49, 2009), the significant conceptual and methodological limitations of the existing work ethic and work value research elucidate the need for a more robust investigation of the multidimensional work ethic construct in the Arab context. Multidimensionality of the work ethic concept has gained considerable attention in recent years as researchers attempt to move away from the religiously labeled Islamic and Protestant work ethic conceptualizations. The current study examines (...) the Arab work ethic through the use of the multidimensional work ethic profile on a sample of future business leaders in the United Arab Emirates. A total of 484 business students completed an Arabic version of the MWEP short form. The results show that centrality of work and hard work are the highest scoring work ethics followed by self-reliance, wasted time, and leisure. There are significant differences in work ethic dimensions across gender and categories of family breadwinner. No significant differences in work ethic dimensions are observed across categories of nationality and work preference groups. The findings are discussed in relation to the unique insight they offer on the nature of work ethic in an Arab context. (shrink)

If his enterprise were successful, however, it would go far beyond the “rights issue” and would have a profound impact on all arguments raised in support of euthanasia or physician-assisted suicide.Clarke's major thrust might be termed the argument from posthumous (...) ignorance. He begins with a claim that the process of making a rational decision involves the process of “gaining all possible facts and `imagining' all possible consequences”.

Cells fine‐tune their DNA repair, selecting some regions of the genome in preference to others. In the paradigm case, excision of UV‐induced pyrimidine dimers in mammalian cells, repair is concentrated in transcribed genes, especially in the transcribed strand. This is due both to chromatin structure being looser in transcribing domains, allowing more rapid repair, and to repair enzymes being coupled to RNA polymerases stalled at damage sites; possibly other factors are also involved. Some repair‐defective diseases may involve repair‐transcription coupling: three (...) candidate genes have been suggested.However, preferential excision of pyrimidine dimers is not uniformly linked to transcription. In mammals it varies with species, and with cell differentiation. In Drosophila embryo cells it is absent, and in yeast, the determining factor is nucleosome stability rather than transcription.Repair of other damage departs further from the paradigm, even in some UV‐mimetic lesions. No selectivity is known for repair of the very frequent minor forms of base damage. And the most interesting consequence of selective repair, selective mutagenesis, normally occurs for UV‐induced, but not for spontaneous mutations. The temptation to extrapolate from mammalian UV repair should be resisted. (shrink)

Background Regarding controversial medical services, many have argued that if physicians cannot in good conscience provide a legal medical intervention for which a patient is a candidate, they should refer the requesting patient to an accommodating provider. This study examines what US physicians think a doctor is obligated to do when the doctor thinks it would be immoral to provide a referral. Method The authors conducted a cross-sectional survey of a random sample of 2000 US physicians from all specialties. The (...) primary criterion variable was agreement that physicians have a professional obligation to refer patients for all legal medical services for which the patients are candidates, even if the physician believes that such a referral is immoral. Results Of 1895 eligible physicians, 1032 (55%) responded. 57% of physicians agreed that doctors must refer patients regardless of whether or not the doctor believes the referral itself is immoral. Holding this opinion was independently associated with being more theologically pluralistic, describing oneself as sociopolitically liberal, and indicating that respect for patient autonomy is the most important bioethical principle in one's practice (multivariable ORs, 1.6–2.4). Conclusions Physicians are divided about a professional obligation to refer when the physician believes that referral itself is immoral. These data suggest there is no uncontroversial way to resolve conflicts posed when patients request interventions that their physicians cannot in good conscience provide. (shrink)

Moral pluralism is the norm in contemporary society. Even the best philosophical arguments rarely persuade moral opponents who differ at a foundational level. This has been vividly illustrated in contemporary debates in bioethics surrounding contentious issues such as abortion and euthanasia. It is readily apparent that bioethics discourse lacks an empirical explanation for the broad differences about various topics in bioethics and health policy. In recent years, social and cognitive psychology has generated novel approaches for defining basic differences in moral (...) intuitions generally. We propose that if empirical research using social intuitionist theory explains why people disagree with one another over moral issues, then the results of such research might help people debate their moral differences in a more constructive and civil manner. We illustrate the utility of social intuitionism with data from a national physician survey. (shrink)

McKay & Dennett (M&D) suggest that some positive illusions are adaptive. But there is a bidirectional link between memory and positive illusions: Biased autobiographical memories filter incoming information, and self-enhancing information is preferentially attended and used to update memory. Extending M&D's approach, I ask if certain false memories might be adaptive, defending a broad view of the psychosocial functions of remembering.

Ethical leadership research has primarily relied on social learning and social exchange theories. Although these theories have been generative, additional theoretical perspectives hold the potential to broaden scholars’ understanding of ethical leadership’s effects. In this paper, we examine moral typecasting theory and its unique implications for followers’ leader-directed citizenship behavior. Across two studies employing both survey-based and experimental methods, we offer support for three key predictions consistent with this theory. First, the effect of ethical leadership on leader-directed citizenship behavior is (...) curvilinear, with followers helping highly ethical and highly unethical leaders the least. Second, this effect only emerges in morally intense contexts. Third, this effect is mediated by the follower’s belief in the potential for prosocial impact. Our findings suggest that a follower’s belief that his or her leader is ethical has meaningful, often counterintuitive effects that are not predicted by dominant theories of ethical leadership. These results highlight the potential importance of moral typecasting theory to better understand the dynamics of ethical leadership. (shrink)
