By focusing on the caloric composition of hunted prey species, optimal foraging research has shown that hunters usually make economically rational prey choice decisions. However, research by meat scientists suggests that the gustatory appeal of wildlife meats may vary dramatically. In this study, behavioral research indicates that Mayangna and Miskito hunters in Nicaragua inconsistently pursue multiple prey types in the optimal diet set. We use cognitive methods, including unconstrained pile sorts and cultural consensus analysis, to investigate the hypothesis that these (...) partial preferences are influenced by considerations of meat flavor. Native informants exhibit high agreement on the relative appeal of different meats. Given the absence of other noteworthy differences between spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta palliata), the unappealing flavor of howler monkeys seems to be a factor in the partial preference for this species.

For International Relations scholars, discussions of globalization inevitably turn to questions of sovereignty. How much control does a country have over its borders, people and economy? Where does that authority come from? _Sovereign Lives_ explores these changes through reading of humanitarian intervention, human rights discourses, securitization, refugees, the fragmentation of identities and the practices of development.

Background:Moral distress occurs when constraints prevent healthcare providers from acting in accordance with their core moral values to provide good patient care. The experience of moral distress in nurses might be magnified during the current Covid-19 pandemic.Objective:To explore causes of moral distress in nurses caring for Covid-19 patients and identify strategies to enhance their moral resiliency.Research design:A qualitative study using a qualitative content analysis of focus group discussions and in-depth interviews. We purposively sampled 31 nurses caring for Covid-19 patients in (...) the acute care units within large academic medical systems in Maryland and New York City during April to June 2020.Ethical considerations:We obtained approval from the Institutional Review Board at the University of Maryland, Baltimore.Results:We identified themes and sub-themes representative of major causes of moral distress in nurses caring Covid-19 patients. These included (a) lack of knowledge and uncertainty regarding how to treat a new illness; (b) being overwhelmed by the depth and breadth of the Covid-19 illness; (c) fear of exposure to the virus leading to suboptimal care; (d) adopting a team model of nursing care that caused intra-professional tensions and miscommunications; (e) policies to reduce viral transmission (visitation policy and PPE policy) that prevented nurses to assume their caring role; (f) practicing within crisis standards of care; and (g) dealing with medical resource scarcity. Participants discussed their coping mechanisms and suggested future strategies.Discussion/Conclusion:Our study affirms new causes of moral distress related to the Covid-19 pandemic. Institutions need to develop a supportive ethical climate that can restore nurses’ moral resiliency. Such a climate should include non-hierarchical interdisciplinary spaces where all providers can meet together as moral peers to discuss their experiences. (shrink)

Student evaluations of teaching are ubiquitous in the academe as a metric for assessing teaching and frequently used in critical personnel decisions. Yet, there is ample evidence documenting both measurement and equity bias in these assessments. Student Evaluations of Teaching have low or no correlation with learning. Furthermore, scholars using different data and different methodologies routinely find that women faculty, faculty of color, and other marginalized groups are subject to a disadvantage in SETs. Extant research on bias on teaching evaluations (...) tend to review only the aspect of the literature most pertinent to that study. In this paper, we review a novel dataset of over 100 articles on bias in student evaluations of teaching and provide a nuanced review of this broad but established literature. We find that women and other marginalized groups do face significant biases in standard evaluations of teaching – however, the effect of gender is conditional upon other factors. We conclude with recommendations for the judicious use of SETs and avenues for future research. (shrink)

This paper offers four contrasting perspectives on the role of the nurse ethicist from authors based in different areas of world, with different professional backgrounds and at different career stages. Each author raises questions about how to understand the role of the nurse ethicist. The first author reflects upon their career, the scope and purpose of their work, ultimately arguing that the distinction between ‘nurse ethicist’ and ‘clinical ethicist’ is largely irrelevant. The second author describes the impact and value that (...) a nurse in an ethics role plays, highlighting the ‘tacit knowledge’ and ‘lived experience’ they bring to clinical ethics consultation. However, the second author also warns that the ‘nurse ethicist’ must be cautious in their approach to avoid being viewed as a resource only for nurses. The third author questions the introduction of additional professional distinctions such as ‘nurse ethicist’ on the basis that distinctions threaten the creation of egalitarian healthcare systems, while also acknowledging that clinical ethicists ought not strive for objective attachment in their work. In direct contrast, the final author suggests that the nurse ethicist can play a pivotal role in highlighting and addressing ethical challenges that are specific to nurses. These four short pieces raise questions and point to concepts that will be expanded upon and debated throughout this special issue of Nursing Ethics. (shrink)

The authors explore the changing dynamics of gendered familial caregiving in urban China within the context of economic reforms and the continued cultural influence of xiao. Data collected in China through interviews with 110 familial caregivers were used to examine cultural and structural influences on the caregiving behavior of adult children. Results from multiple regression analyses provide evidence of a gendered division of parental care tasks, a decline in the patrilocal tradition of caregiving, and a strong social pressure that influences (...) caregiving behavior. Structural factors linked to caregiving performance included family size, lack of pensions for elders, and caregivers’ employment status and income. Findings portend deleterious effects for the women who are now caregivers as they are likely to live longer but be more financially dependent and have fewer children available to help them. (shrink)

A diagnosis of dementia often comes with difficulties in understanding a conversational context and expressing how one feels. So far, research on how to facilitate advance care planning for people with dementia focused on defining relevant themes and topics for conversations, or on how to formalize decisions made by surrogate decision makers, e.g., family members. The aim of this review is to provide a better scope of the existing research on practical communication aspects related to dementia in ACP conversations. In (...) November 2020, seven databases were searched to select papers for inclusion. This search was updated in December 2021. The search strategy consisted of three tiers, intersected by using the Boolean term “AND,” and resulted in 787 studies. Two researchers followed explicit criteria for two sequential levels of screening, based on titles and abstracts and full papers. A total of 22 studies were included for data analysis. Seven topics emerged clustered around two themes. This scoping review provides practical suggestions for healthcare professionals to improve ACP communication and uncovered gaps in research on communication aspects related to dementia in ACP conversations, such as non-verbal behavior, timing and implementation, and personal preferences.

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient’s values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge (...) the information needs of the individual patient. The aim of this paper is to describe ‘core information sets’ which are defined as a minimum set of consensus-derived information about a given procedure to be discussed with all patients. Importantly, they are intended to catalyse discussion of subjective importance to individuals. The model described in this paper applies health services research and Delphi consensus-building methods to an idea orginally proposed 30 years ago. The hypothesis is that, first, large amounts of potentially-important information are distilled down to discrete information domains. These are then, secondly, rated by key stakeholders in multiple iterations, so that core information of agreed importance can be defined. We argue that this scientific approach is key to identifying information important to all stakeholders, which may otherwise be communicated poorly or omitted from discussions entirely. Our methods apply systematic review, qualitative, survey and consensus-building techniques to define this ‘core information’. We propose that such information addresses the ‘reasonable patient’ standard for information disclosure but, more importantly, can serve as a spring board for high-value discussion of importance to the individual patient. The application of established research methods can define information of core importance to informed consent. Further work will establish how best to incorporate this model in routine practice.

The specialist field of intellectual disability nursing has been subjected to a number of changes since the move towards deinstitutionalisation from the 1970s. Government policies sought to change the nature of the disability workforce from what was labelled as a medicalised approach, towards a more socially oriented model of support. Decades on however, many nurses who specialise in the care of people with intellectual disability are still employed. In Australia, the advent of the National Disability Insurance Scheme offers an apt (...) moment to reflect upon these decades of specialised nursing care as the context of this nursing care will continue to evolve. A review of the published literature was conducted to explore what has shaped the field in the past and how this might inform the future of this speciality area under new policy and service contexts. People with intellectual disability have specific health and support needs that require a specialised workforce. Specialist nurses continue to be needed for people with intellectual disability.

To understand public discourse in the United States on genetic causation of behavioral disorders, we analyzed media representations of genetic research on addiction published between 1990 and 2010. We conclude first that the media simplistically represent biological bases of addiction and willpower as being mutually exclusive: behaviors are either genetically determined, or they are a choice. Second, most articles provide only cursory or no treatment of the environmental contribution. A media focus on genetics directs attention away from environmental factors. Rhetorically, (...) media neglect the complexity underlying the etiology the addiction and direct focus back toward individual causation and responsibility. (shrink)

This essay considers how the Zhuangzi 莊子 sheds light on a new direction to the contemporary discussion of desires. Harry Frankfurt proposes an account of personhood based on a hierarchy of desires. He defines a wanton as a being that does not have second-order volitions, the desires that a certain desire of action becomes her will. J. David Velleman proposes, in the context of the Zhuangzi, that when a Daoist sage performs her skills she can be regarded as a “higher” (...) wanton because her actions are spontaneous flows of skillful actions. In this essay, I propose along the line of Velleman a constructive interpretation of the Zhuangzian way to deal with desires from my reading of the Zhuangzi. I argue that there are two roles a Daoist sage can play: the observer and the performer. A Daoist sage can be an observer at a certain time and a performer at other times. Although a performer can be regarded as a higher wanton, it is inappropriate to regard an observer as a wanton. Also, I propose that observation is a means to transform desires—once the practitioner achieves high spirituality, one does not need to possess second-order volitions because one’s first-order desires are transformed such that they are in accordance with the Dao 道.

Voluntades anticipadas: desafíos éticos en el cuidado del paciente Diretivas antecipadas de vontade: desafios éticos no cuidado do paciente Advance healthcare directives are intended for the individual to personally express their will and preferences about healthcare and treatment ahead of time. This literature review aims to describe the concept and structure of advance directives and the ethical aspects involved in patient care. Using the keywords “Advance Healthcare Directive” AND “Ethical Implication” and its Spanish equivalents, five databases were accessed: ProQuest, Philosophy, (...) PubMed, Web of Science and Scielo. Publications were narrowed down to the 2010-2018 period. Thirty-one articles were obtained and read critically. Results of this review were grouped into the following categories: concept, structure, clinical situations in which advance directives apply, strengths and limitations, as well as the ethical aspects involved. End of life-related experiences in which a person loses their ability to make decisions and cannot express their wishes, so it is impossible to know their will, are more common nowadays. Most health workers are not appropriately trained in the preparation and application of advance directives, which becomes an opportunity to research and delve deeper into the subject. Advance directives are a tool that gives health workers reliable information on a patient’s values and wishes, so it is vital to train them to provide respectful quality care.

The meaning of κερτομω and its congeners in Homer has been the subject of debate in this journal. Jones has argued that ‘to κερτομω someone is to speak in such a way as to provoke a powerful emotional reaction’, whether of anger or fear, and thus means ‘“to utter stinging words at [someone]”, “pierce to the heart”, “cut to the quick”, rather than merely “provoke” This definition seems to work well enough for some cases, but certainly not for all, and (...) especially not for the passage from which the whole controversy began: Iliad 24.649, where Achilles speaks to Priam ༐πικερτομέωυ. As Richardson says in his Iliad commentary, ‘there is no sign that Akhilleus’ speech has this direct effect [i.e. arouses fear] on Priam’. Jones's article was responding to an earlier one by J. T. Hooker, who attempted to ascertain the sense of Achilles’ ༐πικερτομέυ by surveying the usage of kertom- words throughout Homeric epic. He concluded that the basic meaning is ‘to taunt’ or, more abstractly, it ‘indicates the provocation of another person into behaving in a certain way, whether that is the behaviour desired by the speaker… or is not desired by the speaker’. The problem was that this definition did not seem to fit the very line from which his inquiry began, the words of Achilles to Priam. Hooker then hypothesized that the verse betrayed signs of an ‘imperfect adaptation’ of a different version of the poem in which Achilles taunted a defeated enemy or perhaps preserved his grudge against Agamemnon to its end. This explanation is unpersuasive. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The opening chapter of this work is a comprehensive “Historical Overview of the Hereditary Puzzle.” Goldie Morgentaler's analysis of theories of heredity before Mendel will interest students of biological science. She admits that “resurrecting such theories without contamination from subsequent knowledge often requires an imaginative leap.” Very true. There have been such profound advances in the science of genetics since that time, with the avalanche of discoveries during the past half century, that much of the previous thought now falls in (...) the realm of philosophical fantasy.These early concepts were those to which Charles Dickens was exposed for most of his life. His literary reaction to them is exhaustively analyzed in the subsequent two parts of the book. The first of these is entitled “Heredity and the Individual,” and the second is “The Public Face of Heredity.” The latter includes interesting discussion of class and race, with analyses of the last three novels. These indicate that Dickens's views on heredity changed during his later life, perhaps influenced by Darwin, whose work he had read … and vice versa.The author is to be admired for her detailed knowledge of Dickens's works and his characters. For a reviewer who has been steeped in evidence‐based medicine and science for most of his career, it seems that much of the speculation regarding heredity in the nineteenth century is tenuous and far‐fetched. While Dickens engaged the topic of heredity many times, he appears to have followed the general trend of that era by showing little consistency in his views. This is not surprising in light of the paucity of scientific evidence at that time.While the title implies a study of Dickens and heredity, the substance covers a much wider field, with ventures into ethics, morality, religion, psychology, philosophy, sociology, and more. The appended notes tell of assiduous research and concentration. To the pragmatic reader it sometimes appears that Morgentaler makes observations and draws conclusions that are more profound than Dickens himself might have achieved, or admitted. This is, of course, a common diversion in revisionist studies of well‐known authors and other celebrities.It is inevitable that the perennial question of the relative strength of nature and nurture must have prominence in this study. In his earlier novels Dickens implied support for the notion that goodness and virtue were heritable traits allied to beauty and good physical appearance. Morgentaler returns repeatedly to this question in many aspects. In her final chapter she points out that Dickens's views changed, paradoxically, after The Origin of Species was published, toward the end of his life. He then gave less weight to the influence of heredity. She has, perhaps, missed an opportunity of recording that Dickens noticed hereditary factors in alcoholism and longevity. In the case of Jenny Wren's family, Mr. Cleaver was “like his own father, a weak wretched trembling creature, falling to pieces, never sober” . The Wardle family in Pickwick Papers showed familial longevity in that “only one member hasn't lived to eighty‐five, and he was beheaded by one of the Henrys.”The relationship of some of the discussion to heredity is profound, often remote, even cryptic. To those who are hybrids of a scientific historian and an obsessive Dickens aficionado, this work will be absorbing. Unfortunately for the author and the publisher, such hybrids are probably rare—but I hope not extinct. To the pure scientist this work might be an uphill exercise. The production of the book is faultless. (shrink)
