Males are often found to outperform females in tests of mathematics achievement and it has been proposed that this may in part be explained by differences in cognitive style. This study investigated the relation between Wholistic-Analytic and Verbal-Imagery cognitive style, gender and mathematics achievement in a sample of 190 Australian primary school students aged between 8?11?years (M?=?9.77, SD?=?1.05). It was hypothesised that males would outperform females in mathematics achievement tests, and that gender would interact with cognitive style on mathematics performance. (...) A significant gender/cognitive style interaction was found. Boys with an Analytic/Imagery style achieved significantly higher results than the girls with an Analytic/Imagery style, supporting the contention that certain cognitive styles affect boys and girls mathematics performance differently. Implications of results and strategies for improving mathematics achievement among girls are discussed. (shrink)

Many think doing animal ethics demands we see moral humanism as a speciesist prejudice of the kind found with sexism and racism. The only serious case for this rests on the Argument from Marginal Cases. We find that argument to the point, but show that properly understood it supports humanism. Understanding why it does this lets us see how we ought to go on in animal ethics.

This article explores the evolution of Principles of Biomedical Ethics by Tom Beauchamp and James Childress over its seven editions. Many changes have occurred in the text over the last thirty-five years, including the expansion of the section on virtue ethics, the modification of the authors’ position on physician-assisted suicide, and the addition of many other ethical theories to the original two found in the first editions. The basis for these changes and others seems to be their development of the (...) theme of the “common morality.” The author suggests that Beauchamp and Childress develop the connection between their common morality and metaphysics, as it would serve to strengthen their theory and make it less susceptible to changes in society’s opinions and traditions. National Catholic Bioethics Quarterly 14.3 : 459–475. (shrink)

Considering the popular framing of an artificial intelligence as a rational agent that always seeks to maximise its expected utility, referred to as its goal, one of the features attributed to such rational agents is that they will never select an action which will change their goal. Therefore, if such an agent is to be friendly towards humanity, one argument goes, we must understand how to specify this friendliness in terms of a utility function. Wolfhart Totschnig, argues in contrast that (...) a fully autonomous agent will have the ability to change its utility function and will do so guided by its values. This commentary examines computational accounts of goals, values and decision-making. It rejects the idea that a rational agent will never select an action that changes its goal but also argues that an artificial intelligence is unlikely to be purely rational in terms of always acting to maximise a utility function. It nevertheless also challenges the idea that an agent which does not change its goal cannot be considered fully autonomous. It does agree that values are an important component of decision-making and explores a number of reasons why. (shrink)

A vital process in maintaining a low genetic error rate is the removal of mismatched bases in DNA. The importance of this process in E. coli is demonstrated by the 100–1000 fold increase in mutation frequency observed in cells deficient in this repair system(1). Mismatches can arise as a consequence of recombination, errors in replication and as a result of spontaneous chemical deamination, the latter process resulting in an estimated twelve T:G mismatches per genome per day in mammalian cells(2). Recent (...) studies, discussed here, provide evidence for the existence of specific mismatch repair systems in mammalian and human cells. (shrink)

During the debates about the legalization of Voluntary Assisted Dying in Victoria, Australia, the presence of anti-VAD health professionals in the medical community and reported high rates of conscientious objection to VAD suggested access may be limited. Most empirical research on CO has been conducted in the sexual and reproductive health context. However, given the fundamental differences in the nature of such procedures and the legislation governing it, these findings may not be directly transferable to VAD. Accordingly, we sought to (...) understand how CO operates in the context of VAD. Prior to the implementation of the VAD legislation in June 2019, we conducted semi-structured interviews with seventeen health professionals with a self-declared CO to VAD, to explore what motivated their CO. Participants identified multiple motivations, which can be broadly categorized as: concerns for oneself; concerns for patients; concerns about the current Victorian legislation; and concerns for the medical profession. Participants’ moral commitments included personal, professional, and political commitments. In some cases, one’s CO was specific to Victoria’s current legislation rather than VAD more broadly. Our findings suggest CO motivations extend beyond those traditionally cited and suggest a need to better understand and manage CO in the healthcare context. (shrink)

Research using explicit measures has linked decreased positive future thinking, but not increased negative future thinking, with clinical depression. However, individuals may be unable or unwilling to express thoughts about the future, and can be unaware of implicit beliefs that can influence their behavior. Implicit measures of cognition may shed light on the role of future thinking in depression. To our knowledge, the current study presents the first implicit measure of positive and negative future thinking. A sample of 71 volunteers (...) completed both implicit and explicit measures of positive and negative future thinking. The findings indicate differences in the evaluation of both positive and negative future events between the two groups. However, group differences were more pronounced on the implicit measure. These findings point to the potential utility of an implicit measure of future thinking in mental health research and clinical practice. (shrink)

The present study assessed whether dementia worry is associated with adults’ subjective cognitive difficulties, and whether any associations are moderated by age. Participants were 477 adults aged 18–90 years. They completed standard, subjective measures of dementia worry and everyday cognitive difficulties (i.e. attention, language, verbal and visual-spatial memory, and visual-perceptual ability). Moderated regression analyses included dementia worry as a predictor of specific cognitive difficulties, and age as a moderator. Covariates included gender, trait cognitive and somatic anxiety, general aging-related anxiety, depression, (...) stress, mental health treatment status, and health status. Greater overall dementia worry, and specifically more frequent dementia worry, were both associated with greater attentional difficulty in middle-aged and older adults, but not in young adults. Cognitions about developing dementia in reaction to memory lapses were also associated with greater cognitive difficulties across the adult lifespan for multiple cognitive domains. Results highlight a robust relationship between dementia worry and subjective attentional difficulties, especially in middle-aged and older adults. Worry frequency is also more influential with adult aging. A cognitive or meta-cognitive mechanism may underlie subjective cognitive concerns across the adult lifespan. (shrink)

The decision to divorce marks a turning point for every individual involved. It can be viewed as more than just a legal process. From a psychological perspective, it does not matter who initiated the divorce, since it always comes with emotional ramifications for all those involved. Statistically, there is a high rate of divorce in South Africa and there have been significant shifts in trends over time. While black South African men’s experience of divorce has been relatively neglected in the (...) research on divorce, it is important for understanding contemporary social arrangements and processes, and, in particular, for broadening the understanding of black South African men’s lives. How black South African men describe their experience and respond to marital dissolution may point to their positions in the gender-structured community as well as illuminate how they interpret the nature of social practice, marriage, divorce and their position in society. The aim of the research reported on in this paper was to explore black South African men’s experience of divorce. The theoretical framework underpinning this qualitative study was broadly that of Symbolic Interactionism, with Interpretative Phenomenological Analysis employed as both the research design and data analytic theory and process. The eight participants were volunteers who were recruited purposively. In keeping with IPA guidelines, data-collection proceeded by means of biographical questionnaires and semi-structured interviews. The emerging themes were grouped into three superordinate themes, namely, perceptions of divorce, social support, and experiencing of pain. Each superordinate theme had corresponding subordinate themes and experiential claims. Weed’s recommendations for the interpretative synthesis of interview data were applied. (shrink)

The development of clinical ethic support in the UK arguably brings with it a series of legal questions, which need to be addressed. Most particularly, these concern questions of due process and formal justice, which I argue are central to the provision of appropriate ethical advice. In this article, I will compare the UK position with the more developed system in the USA, which often provides a template for development in the UK. While it is not argued that the provision (...) of clinical ethics support in the UK will necessarily follow the path mapped in the USA, there are lessons that can be learned from the US experience – particularly in terms of attention to process – from which UK clinical ethics support service might well benefit.

There are wide individual differences in the ability to detect a stimulus contingency embedded in a complex paradigm. The present study used a cognitive masking paradigm to better understand individual differences related to contingency learning. Participants were assessed on measures of electrodermal arousal and on working memory capacity before engaging in the contingency learning task. Contingency awareness was assessed both by trial-by-trial verbal reports obtained during the task and by a short post-task recognition questionnaire. Participants who became aware had fewer (...) non-specific skin conductance responses and tended to score higher on a digit span assessment. Skin conductance level was not significantly lower in the aware group than in the unaware group. These findings are consistent with studies showing that lower arousal and greater cognitive processing capacity facilitate conscious perception of a greater breadth of information within a scene or a task.

As support for clinical ethics committees in the UK grows, care must be taken to define their function, membership and method of working and the status of their decisions.The modern practice of medicine raises a plethora of complex issues—medical, ethical and legal. Doctors and other healthcare professionals increasingly must try to resolve these and may sometimes have to do so in the face of contrary opinion expressed by patients and/or their surrogates. While clearly qualified in the medical arena, and although (...) there is now more ethics teaching in the medical curriculum, healthcare professionals are seldom qualified to adjudicate on ethical or legal matters, or even, perhaps, to recognise them when they arise. Yet, as Doyal says, “clinical life must go on and moral and legal indeterminacy within medicine cries out for practical resolution.”1 Meanwhile, the expectations of patients and their families—and, indeed, of wider society—are that decisions about patient care, resources and therapeutic regimes should be soundly based on appropriate ethicolegal, as well as scientific, principle.Recognition of these additional burdens on healthcare professionals has generated some interest in the provision of ethics consultation. In the USA this has been undertaken by a variety of tribunals and individuals. Hospital ethics committees and ethics consultants feature in many US hospitals and perform a variety of roles. In Europe, a number of countries have also established clinical ethics committees and they are becoming more common in the UK—primarily in England and Wales for the moment. Whereas, however, “[i]n North America, CECs have … become an integral part of the organisational infrastructure of hospitals ...”,1 in the United Kingdom they remain essentially ad hoc bodies, generated for a variety of reasons and with different goals, structures, membership, methods of working and functions. The initial impetus for the …. (shrink)

A medical profession which did not seek improved means to conquer disease would be condemned for dereliction of its duty, Members of the public will not accept the current state of the medical arts as finite but feel justified in expecting the development of more effective therapies for illness, and the promotion of improved means of preventive care.With this assertion, the distinguished academic, Bernard Dickens, places research firmly in the domain of the public interest. Foster agrees, saying that, “[t]o improve (...) medical care as much as we can, if not to perfect it, means that we have to accept the need for research.” Giesen adds a further emphasis to the search for medical advancements, saying that “freedom of research and scientific inquiry is, in itself, an important aspect of open societies.“.

This is an extremely readable and interesting contribution. The author takes the reader through the Patient Self-Determination Act in some depth, but doesn't make any attempt to look at its provisions in real detail. This cannot be taken as an omission, as the purpose of the book is to explore the principles underpinning the legislation and to explore its ethical content. In that respect, this is a very interesting exercise. On one ….

The controversies in Bristol, Alder Hey and elsewhere in the UK surrounding the removal and retention of human tissue and organs have led to extensive law reform in all three UK legal systems. This paper reports a short study of the reactions of a range of health professionals to these changes. Three main areas of ethical concern were noted: the balancing of individual rights and social benefit; the efficacy of the new procedures for consent; and the helpfulness for professional practice (...) of the new legislation and regulation. Recognition of these concerns may help in forging a new partnership between professionals and patients and their families. (shrink)

The patient-doctor relationship has recently come under intense scrutiny, resulting in a re-evaluation of the basis of that relationship. The papers by Glannon and Ross, and McKay seek to identify the sources of authority in the patient-doctor relationship by evaluating it in terms of the concept of altruism. In this paper I argue that the analysis of Glannon and Ross, and of McKay is unnecessary and that the analysis offered by the latter is also flawed. I do acknowledge, however, that (...) Glannon and Ross's description of doctors' responsibilities and patients' roles has much to commend it. (shrink)

In recent years there have been major shifts in how the role of science—and scientists—are understood. The critical examination of scientific expertise within the field of Science and Technology Studies are increasingly eroding notions of the “otherness” of scientists. It would seem to suggest that anyone can be a scientist—when provided with the appropriate training and access to data. In contrast, however, ethnographic evidence from the scientific community tells a different story. Scientists are quick to recognize that not everyone can—or (...) should—be a scientist. Appealing to notions such as “good hands” or “gut feelings”, scientists narrate a distinction between good and bad scientists that cannot be reduced to education, access, or opportunity. The key to good science requires scientists to express an intuitive feeling for their discipline, but also that individuals derive considerable personal satisfaction from their work. Discussing this personal joy in—and “fittingness” of—scientific occupations using the fields of STS, ethics and science policy is highly problematic. In this paper we turn to theology discourse to analyze the notion of “callings” as a means of understanding this issue. Callings highlight the identification and examination of individual talents to determine fit occupations for specific persons. Framing science as a calling represents a novel view of research that places the talents and dispositions of individuals and their relationship to the community at the center of flourishing practices.

The system of clinical ethics committees (CECs) in the United Kingdom is based on goodwill. No formal requirements exist as to constitution, membership, range of expertise or the status of their recommendations. Healthcare professionals are not obliged to use CECs where they exist, nor to follow any advice received. In addition, the make-up of CECs suggests that ethics itself may be under-represented. In most cases, there is one member with a training in ethics – the rest are healthcare professionals or (...) administrators, although a lawyer is generally also included in the membership. This begs the question as whether CECs can ‘do ethics’, as well whether or not they can take seriously the requirements of due process, formal justice and human rights. Moreover, the role of the patient in this system is opaque. (shrink)

Development-oriented funding schemes such as the UK Global Challenges Research Fund (GCRF) have opened up opportunities for collaborations between low-middle income countries (LMICs) and high-income country (HIC) researchers. In particular, funding for medical technology research has seen a rise in previously under-represented disciplines such as physics and engineering. These collaborations have considerable potential to advance healthcare in LMICs, yet can pose challenges experienced to researchers undertaking these collaborations. Key challenges include a lack of tradition of HIC/LMIC collaborations within participating departments, (...) lack of experience with development agendas, designing contextually-appropriate technologies and ensuring long-term viability of research outputs. This paper reflects on these key challenges, using the experiences of the authors on the Open Laboratory Instrumentation (OLI) project as a focalizing lens. This project was a GCRF-funded collaboration between physicists in the UK and engineers in Tanzania to develop an open-source, 3D-printed, fully-automated laboratory microscope. The paper highlights key ethics lessons learnt. (shrink)

Canadian and international nursing educators are increasingly concerned with the quality of university nursing education. Contemporary nursing education is fraught by a growing anti‐intellectualism coupled with the dominance of neoliberalism and corporate university business culture. Amid these challenges, nursing schools must prepare nurses to provide care in an era compounded by social and health inequities. The purpose of this paper was to explore the philosophical and contextual factors influencing anti‐intellectualism in nursing education. We use John Henry Newman's view of the (...) purpose of a university education as a heuristic perspective to examine anti‐intellectualism in nursing. We contend that the ideological worship of technological advances, a culture of consumerism, quality improvement and risk management, the primacy of doing over thinking, competency‐based curricula and business models rooted in neoliberal financial policies reinforce anti‐intellectualism in nursing. Anti‐intellectualism is a complex issue to address within the corporate university culture. We propose multiple strategies at the disciplinary, university and sociopolitical levels to decrease anti‐intellectualism. Counteracting anti‐intellectualism requires critical thinking, praxis and emancipation. Nurses should critically examine this anti‐intellectual trend as it limits the advancement of the discipline and marginalizes its contributions within the academy. If nurses do not address this challenge, the survival of nursing as an academic discipline may be jeopardized. (shrink)

Cet ouvrage s'inscrit dans le fil du travail collectif entrepris en 1995, l'Histoire de la pensée médicale en Occident (trois volumes sous la direction de Mirko D Grmek, Seuil, 1995, 1997, 1999). Il rend compte du déploiement des recherches pluridisciplinaires et transdisciplinaires de la pensée médicale et aborde les discussions et controverses actuelles sur les politiques de santé. Du fait du développement des connaissances théoriques et des innovations techniques, la notion même de soin, sous ses aspects sociaux, économiques, mais aussi (...) épistémiques, se trouve questionnée. La pensée médicale ne saurait se limiter aux données biologiques, et ses composantes spécifiquement humaines et sociales sont explorées et interrogées ici dans une perspective historique qui tient compte des découvertes du dernier siècle.
