We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions—color, movement, and shape—thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that (...) described it (e.g., arrogant, caring, confident). Participants were given training on the alien‐attribute assignments and were then tested on their memory for these. The alien‐attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype‐like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information. (shrink)

This paper takes as its starting point a debate between Harry Frankfurt and J. David Velleman. Frankfurt argues that we need to resolve ambivalence since it necessarily threatens autonomy. Velleman challenges this claim, arguing that a desire to resolve ambivalence threatens autonomy when it prompts repression. I argue that the relationship between ambivalence and autonomy is more ambiguous than either theorist tends to acknowledge. In doing so, I recommend three features relevant for assessing whether or not ambivalence threatens autonomy.

We examined unconscious priming in a stem-completion task with both identity and form-related primes. Participants were given exclusion instructions to avoid completing a stem with a briefly flashed masked word . In Experiment 1, priming of around 7% occurred for both identity and form-based primes at a 33 ms exposure duration. When examining only trials in which the participants failed to identify the prime, this effect increased to 12% for identity primes, but remained the same for form-based primes. In Experiment (...) 2, priming without prime identification was 9% for identity primes, 4% for homophone primes, and 3% for orthographic control primes. Although identity priming was greater than form priming in both experiments, regression analyses revealed that orthographic and phonological overlap alone between the flashed primes and targets could completely account for unconscious identity priming. Hence, we conclude that masked words may only activate their sublexical orthographic and phonological representations and not their lexical representations. (shrink)

Feminist Geneaologies, Colonial Legacies, Democratic Futures provides a feminist anaylsis of the questions of sexual and gender politics, economic and cultural marginality, and anti-racist and anti-colonial practices both in the "West" and in the "Third World." This collection, edited by Jacqui Alexander and Chandra Talpade Mohanty, charts the underlying theoretical perspectives and organization practices of the different varieties of feminism that take on questions of colonialism, imperialism, and the repressive rule of colonial, post-colonial and advanced capitalist nation-states. It provides (...) a comparative, relational, historically grounded conception of feminist praxis that differs markedly from the liberal pluralist, multicultural understanding that sheapes some of the dominant version of Euro-American feminism. As a whole, the collection poses a unique challenge to the naturalization of gender based in the experiences, histories and practices of Euro-American women. (shrink)

In this article, I describe how gender bias can affect the design, testing, clinical trials, regulatory approval, and clinical use of implantable devices. I argue that bad outcomes experienced by women patients are a cumulative consequence of small biases and inattention at various points of the design, testing, and regulatory process. However, specific instances of inattention and bias can be difficult to identify, and risks are difficult to predict. This means that even if systematic gender bias in implant design is (...) an ethical issue, it is one with no clearly blameworthy player. From a practical perspective, there is no single obvious point at which to intervene. Philosophers working in other areas have explored structurally similar moral problems—sometimes referred to as “moral aggregation problems”—such as the type of environmental harm caused by small actions of many players. I describe key features of these type of problems and strategies to address them. I then draw on these to suggest an approach to gender bias in medical implant design and use. (shrink)

This book forms part of the multi-disciplinary Studies in Ethics Series from Liverpool Hope University. It explores the slipperiness of ethics as a concept and demonstrates the multiplicity of intellectual inquiry within contemporary Film Studies. At first glance, â ~ethicsâ (TM) is not necessarily a subject conventionally associated with film. Film is often regarded as a form of â ~lowbrowâ (TM) popular culture, either offering bland entertainment or deliberately setting out to shock â " or, more cynically, generate box office (...) revenue â " through gratuitous inclusion of sex and violence. Certainly, there have always been a minority of films based on the stereotypically â ~ethicalâ (TM) subject of religion, but these have often generated the most controversy, from the studio system decree that it was blasphemous to represent the corporeal body of Christ to the furore surrounding Martin Scorseseâ (TM)s The Last Temptation of Christ (1988). This book shows that from the silent era to the present day, film has been inherently concerned with ethical issues. In this light, the definition of ethics that informs the volume and is taken as the starting point of each of the chapters is the notion of personal or institutional motivation; most usually because a character or industry figure makes a decision or choice based on their own moral â " or ethical â " code. Once this is defined, the ethical dimension to films is immediately evident. This book takes as its central theme the difficulty of decisions refracted through personal ethical codes, and thus recognises that what counts as ethics, or morality, is always subjective. Some of the chapters explore films which take conventionally â ~goodâ (TM) ethical standpoints, others investigate why â ~badâ (TM) decisions were made; at least one explores the celebration of practices invoking popular disgust, but all the contributions study ethical decisions within film that represent the strongly felt convictions of those involved and, moreover, address aspects of filmmaking which force the spectator to be an active and reciprocal participant in the creation of meaning, thus implicitly acknowledging that ethics are subjective and in perpetual flux rather than fixed, objective truths.

With reference to examples of violence during Apartheid, I argue that the socio-political contexts in which violence occurs significantly shape agents ideas about and responses to violence. As such, philosophers can only make sense of why perpetrators and bystanders alike may have judged violent acts morally justifiable or failed to challenge instances of violence against the backdrop of the particular characteristics of the socio-political context in which it occurs.

What does world peace mean? Peace is more than the absence and prevention of war, whether international or civil, yet most of our ways of conceptualizing and measuring peace amount to just that definition. In this essay, as part of the roundtable “World Peace (And How We Can Achieve It),” I argue that any vision of world peace must grapple not only with war but with the continuums of violence and peace emphasized by feminists: running from the home and community (...) to the public spaces of international relations. Breaking free of the constraints of the last century's intellectual boundaries, I suggest that war and peace are not a dichotomy but rather are intimately related. Yet the dearth of feminist perspectives in global debates prevents us from seeing how violence and harm are exacerbated in households and through the global economy under conditions of both “war” and “peace.” To understand the possibilities for world peace, we must understand these varieties of violence and harm that threaten peace. And to sustain peace we must address the harmful gendered identities, ideologies, and social dynamics that support violence in every society. A narrow understanding of peace as merely the absence of organized violence does not engender the kind of nuanced and rich understanding of human history and human relations needed to bring an end to the structural and physical violence that remains pervasive worldwide.

This study provides evidence of the significant life experiences , which influence advocates for nonhuman animals to develop sensitivity toward animals. Thirty-nine humane educators participated in an online survey. Findings indicate that having a relationship with a companion animal in adulthood is the most important life experience, followed by having a childhood experience with an animal, being exposed to a positive role model in childhood, and reading about animals and animal issues. The study did not find age and gender related (...) differences in life experiences. This paper compares the results from this study to two previous studies. The first study examined the SLEs of animal advocate leaders through analysis of autobiographies, biographies, oral histories, and written interviews. The second study examined the SLEs of animal rescuers through an open-ended survey. This paper discusses similarities and differences among these three groups. (shrink)

This paper argues against a standard view that all deterministic and conservative classical mechanical systems are time-reversible, by asking how the temporal evolution of a system modulates parametric imprecision (either ontological or epistemic). It notes that well-behaved systems (e.g. inertial motion) can possess a dynamics which is unstable enough to fail at reversing uncertainties—even though exact values are reliably reversed. A limited (but significant) source of irreversibility is thus displayed in classical mechanics, closely analogous the lack of predictability revealed by (...) unstable chaotic systems. (shrink)

This article looks at the discourses of love through an analysis of the ‘stratification of intimacy’ within lesbian families. I suggest that traditional discourses of love effectively reify our emotions into socially prescribed categories, where ‘mature love’ is conflated with sex and desire. The love that mothers feel for their child is set apart, ‘instinctive’, wholly separate to adult love. However this ‘stratification of intimacy’ obscures the lived experiences and feelings of many parents. In this article the author argues that (...) whom we love is culturally constituted: it is unnecessarily quantified whereby monogamy is read as the sign of true love. I illustrate how lesbian mothers’ location on the social margins enables them to construct new ‘patterns of love’ within their ‘families of choice’ in ways that challenge these traditional discourses of love. This theoretical analysis is based upon ‘patterned variations’ drawn from qualitative research with 20 lesbian families with children living within the Yorkshire region in the UK. (shrink)

The effects of the theological revolution have been felt most acutely in European Protestantism, but it has by no means been limited either to Europe or to Protestantism. Its influence has been felt in Judaism, Catholicism, and to a lesser degree in Eastern Orthodoxy. Even Humanism has felt its force. From Europe it has spread to America, and also to Asia and Africa.

Background: When adolescent boys experience close, secure relationships with their parents and peers, the implications are potentially far reaching, including lower levels of mental health problems in adolescence and young adulthood. Here we use rare prospective intergenerational data to extend our understanding of the impact of adolescent attachments on subsequent postpartum mental health problems in early fatherhood.Methods: At age 17–18 years, we used an abbreviated Inventory of Parent and Peer Attachment to assess trust, communication, and alienation reported by 270 male (...) participants in their relationships with mothers, fathers, and peers. More than a decade later, we assessed the adult males, now fathers, at 12 months postpartum for symptoms of depression, anxiety, and stress. Logistic regression was used to examine the extent to which attachment dimensions predicted paternal postpartum mental health, adjusting for potential confounding, and with assessment for interactions between parent and peer attachments.Results: Trust in mothers and peers, and good communication with fathers during adolescence, were associated with 5 to 7 percentage point reductions in postpartum mental health symptoms in early fatherhood. Weak evidence of parent-peer interactions suggested secure attachments with either parent or peer may compensate for an insecure attachment with the other.Conclusions: Our results suggest that fostering trust and communication in relationships that adolescent boys have with parents and peers may have substantial effects on rates of paternal postpartum mental health problems. The protective benefits may be preventative in intergenerational cycles of risk for mental health problems. (shrink)

Martha Nussbaum subscribes to the view that our identity is an evaluative question determined by our common, deeply held beliefs about what is worthwhile in human life. In so doing, she asserts that for an account of ethics to have “philosophical power” it needs to be grounded in an account of human nature that is both evaluative and internal. I focus on Nussbaum's claim that personal identity has to include the necessary features of practical rationality and sociability. Although Nussbaum puts (...) forward self-validating arguments to prove that we cannot – on pain of pragmatic in consistency – dispute that practical rationality and sociability are necessary features of human life, it is my claim that her account is flawed. The nature of the relationship between ethics and human nature is the broader context to such debates. This paper raises questions regarding on the one hand, whether it is possible to found ethics in human nature and, on the other, what we are to make of accounts that turn on the assumption that identity is ethical, not meta physical.

The gut protozoan parasite, Giardia duodenalis, is the best characterized example of the most ancient eukaryotes, which are anaerobic and appear to be primitively amitochondrial. Apart from its obvious medical importance, Giardia is fascinating in its own right. Its prokaryotic-like anaerobic metabolism renders it selectively sensitive to some bacterial drugs, especially the nitroimidazoles, which are activated to form toxic radicals. Other features, including an enzyme that reduces oxygen directly to water, cysteine as the keeper of redox balance, a plasmid, and (...) toxin-like genes are also distinctly prokaryotic-like. But, unlike prokaryotes, Giardia has a sophisticated, highly developed cytoskeleton, bounded nuclei, linear chromosomes capped with telomeric repeats, and telomere positional regulation of gene expression.

Despite its place in the humanities, the career prospects and numbers of women in philosophy much more closely resemble those found in the sciences and engineering. This book collects a series of critical essays by female philosophers pursuing the question of why philosophy continues to be inhospitable to women and what can be done to change it. By examining the social and institutional conditions of contemporary academic philosophy in the Anglophone world as well as its methods, culture, and characteristic commitments, (...) the volume provides a case study in interpretation of one academic discipline in which women's progress seems to have stalled since initial gains made in the 1980s. Some contributors make use of concepts developed in other contexts to explain women's under-representation, including the effects of unconscious biases, stereotype threat, and micro-inequities. Other chapters draw on the resources of feminist philosophy to challenge everyday understandings of time, communication, authority and merit, as these shape effective but often unrecognized forms of discrimination and exclusion. Often it is assumed that women need to change to fit existing institutions. This book instead offers concrete reflections on the way in which philosophy needs to change, in order to accommodate and benefit from the important contribution women's full participation makes to the discipline.

OBJECTIVES: This article presents an original definition of surgical innovation and a practical tool for identifying planned innovations. These will support the responsible introduction of surgical innovations. BACKGROUND: Frameworks developed for the safer introduction of surgical innovations rely upon identifying cases of innovation; oversight cannot occur unless innovations are identified. However, there is no consensus among surgeons about which interventions they consider innovative; existing definitions are vague and impractical. METHODS: Using conceptual analysis, this article synthesizes findings from relevant literature, and (...) from qualitative research with surgeons, to develop an original definition of surgical innovation and a tool for prospectively identifying planned surgical innovations. The tool has been developed in light of feedback from health care professionals, surgeons, and policy makers. RESULTS: This definition of innovation distinguishes between variations, introduction of established interventions, and innovations in surgical techniques or use of devices. It can be applied easily and consistently, is sensitive to the key features of innovation, is prospective, and focuses on features relevant to safety and evaluation. The accompanying tool is deliberately broad so that appropriate supports may, if necessary, be provided each time that a surgeon does something "new". CONCLUSIONS: The definition presented in this article overcomes a number of practical challenges. The definition and tool will be of value in supporting responsible surgical innovation, in particular, through the prospective identification of planned innovations. (shrink)

Surgical innovation promises improvements in healthcare, but it also raises ethical issues including risks of harm to patients, conflicts of interest and increased injustice in access to health care. In this article, we focus on risks of injustice, and use a case study of robotic prostatectomy to identify features of surgical innovation that risk introducing or exacerbating injustices. Interpreting justice as encompassing matters of both efficiency and equity, we first examine questions relating to government decisions about whether to publicly fund (...) access to innovative treatments. Here the case of robotic prostatectomy exemplifies the difficulty of accommodating healthcare priorities such as improving the health of marginalized groups. It also illustrates challenges with estimating the likely long-term costs and benefits of a new intervention, the difficulty of comparing outcomes of an innovative treatment to those of established treatments, and the further complexity associated with patient and surgeon preferences. Once the decision has been made to fund a new procedure, separate issues of justice arise at the level of providing care to individual patients. Here, the case of robotic prostatectomy exemplifies how features of surgical innovation, such as surgeon learning curves and the need for an adequate volume of cases at a treatment centre, can exacerbate injustices associated with treatment cost and the logistics of travelling for treatment. Drawing on our analysis, we conclude by making a number of recommendations for the just introduction of surgical innovations. (shrink)

Patient or public involvement in health research is increasingly expected as a matter of policy. In theory, PPI can contribute both to the epistemic aims intrinsic to research, and to extrinsically valued features of research such as social inclusion and transparency. In practice, the aims of PPI have not always been clear, although there has been a tendency to encourage the involvement of so-called ordinary people who are regarded as representative of an assumed patient perspective. In this paper we focus (...) on the epistemic potential of PPI, using theoretical work in epistemology to develop a nuanced account of patients’ experiential knowledge and how this might contribute directly to conceptual development, hypothesis generation and data interpretation. We also consider how some features of health research pose barriers to this kind of epistemic contribution. Drawing on Miranda Fricker’s idea of testimonial injustice, we explore how disciplinary indicators of credibility in clinical and academic health research contexts might be wrongly applied to those involved in PPI, undermining their potential to contribute. Finally we argue for a range of strategies to maximize opportunities for patients to engage with research teams and make epistemologically significant contributions to research. (shrink)

One day soon it may be possible to replace a failing heart, liver, or kidney with a long-lasting mechanical replacement or perhaps even with a 3-D printed version based on the patient's own tissue. Such artificial organs could make transplant waiting lists and immunosuppression a thing of the past. Supposing that this happens, what will the ongoing care of people with these implants involve? In particular, how will the need to maintain the functioning of artificial organs over an extended period (...) affect patients and their doctors and the responsibilities of those who manufacture such devices? Drawing on lessons from the history of the cardiac pacemaker, this article offers an initial survey of the ethical issues posed by the need to maintain and service artificial organs. We briefly outline the nature and history of cardiac pacemakers, with a particular focus on the need for technical support, maintenance, and replacement of these devices. Drawing on the existing medical literature and on our conversations and correspondence with cardiologists, regulators, and manufacturers, we describe five sources of ethical issues associated with pacemaker maintenance: the location of the devices inside the human body, such that maintenance generates surgical risks; the complexity of the devices, which increases the risk of harms to patients as well as introducing potential injustices in access to treatment; the role of software—particularly software that can be remotely accessed—in the functioning of the devices, which generates privacy and security issues; the impact of continual development and improvement of the device; and the influence of commercial interests in the context of a medical device market in which there are several competing products. Finally, we offer some initial suggestions as to how these questions should be answered. (shrink)
