Mitochondrial replacement therapy (MRT) utilises nuclear transfer technology to replace defective mitochondria with healthy ones and thereby minimise the risk of a mitochondrial disease passing from a mother to her child. It promises much but comes with ethical controversy, significant risk of harm and many unknowns. Forming a position on MRT requires accurate information about the current state of knowledge, and an appreciation of the ethical issues at stake. Ethical deliberations will vary depending on the framework used. There are in (...) principle objections to MRT on the grounds of direct harm to human embryos and germline genetic modification. But even without these objections MRT can be weighed in terms of the balance between risks and benefits, alternatives and uncertainties. This paper explores the evidence and lays out the relevant issues to assist such a deliberation. (shrink)

Reproductive coercion encompasses a collection of pregnancy promoting and pregnancy avoiding behaviours. Coercion may vary in severity and be perpetrated by intimate partners or others. Research is complicated by the inclusion of behaviours that do not necessarily involve an intention to influence reproduction, such as contraceptive sabotage. These behaviours are the most common, but are not always included in survey instruments. This may explain why the prevalence of reproductive coercion varies widely. Prevalence also varies when coerced abortion is included in (...) survey instruments. When it is, it seems roughly comparable in prevalence to coercion intended to impregnate. The extent and nature of coerced abortion can also be derived from studies that explore the reasons why women access abortion, the relationship between abortion and intimate partner violence, and online blogs and forums. This narrative review of reproductive coercion examines the evidence and attempts to comprehend why coerced abortion has been neglected. (shrink)

This paper proposes a causal model of sexual activity among a randomly selected sample of 305 Junior secondary school girls in Zambia. The results indicate that liberal sexual attitudes influence romantic involvement with boys. Emotional involvement is likely to result in sexual activity. Traditional courtship forms are slowly being replaced by modern patterns of courtship behaviour. Policy and programme implications are discussed.

In recent years the science-and-religion/spirituality/theology dialogue has flourished, but the impact on the minds of the general public, on society as a whole, has been less impressive. Also, religious believers and outspoken atheists face each other without progressing toward a common understanding. The view taken here is that achieving a more marked impact of the dialogue would be beneficial for a peaceful survival of humanity. I aim to argue the why and how of that task by analyzing three possible purposes (...) of the dialogue and their logical interdependence, suggest conceivable improvements of the quality and extent of the current efforts toward a negotiated action plan, and consider an enlargement of the circle of the actors involved. The dialogue that has been carried on between science and religion/spirituality/theology could be expanded and usefully applied to some major problems in the present world. (shrink)

It has often been remarked that science is a young man's game. Thomas Kuhn, for example, claims that revolutionary changes in science are almost always initiated by either young scientists or those new to a field. I subject Kuhn's hypothesis to testing. I examine 24 revolutionary scientific figures mentioned in The Structure of Scientific Revolutions to determine if young scientists are more likely to make revolutionary discoveries than older scientists. My analysis suggests that middle-aged scientists are responsible for initiating more (...) scientific revolutions than young scientists, given the proportion of each group in the total population of scientists. I argue that the popular myth about the correlation between youth and scientific discovery fails to take into account the proportion of young scientists in the population of scientists. (shrink)

Written by leading researchers in educational and social psychology, learning science, and neuroscience, this edited volume is suitable for a wide-academic readership. It gives definitions of key terms related to motivation and learning alongside developed explanations of significant findings in the field. It also presents cohesive descriptions concerning how motivation relates to learning, and produces a novel and insightful combination of issues and findings from studies of motivation and/or learning across the authors' collective range of scientific fields. The authors provide (...) a variety of perspectives on motivational constructs and their measurement, which can be used by multiple and distinct scientific communities, both basic and applied.

There are important ethical issues to be examined before launching any public health intervention, particularly when targeting vulnerable groups. The aim of this article is to identify and discuss ethical concerns that may arise when intervening for health behavior change among adolescents identified as overweight. These concerns originate from an intervention designed to capacitate adolescents to increase self-determined physical activity. Utilizing an ethical framework for prevention of overweight and obesity, we identified three ethical aspects as particularly significant: the attribution of (...) responsibility for health behavior, liberty to choose, and the effect on the participants’ psychosocial well-being. It is discussed whether and how measures can be taken to deal with these aspects. It seems evident that the ethical aspects are mainly concerned with the vulnerability of adolescents identified as overweight. However, we claim that when individual feedback and counseling is provided, tailored interventions have a unique potential to empower adolescents to make ethically anchored decisions about their own health behavior.

I examine the citation patterns to a revolutionary scientific paper, Hess’ “History of Ocean Basins”, which played a significant role in the plate tectonics revolution in the geosciences. I test two predictions made by the geoscientist Menard (in Science: growth and change. Harvard University Press, Cambridge, 1971): (1) that the peak year of citations for Hess’ article will be 1968; and (2) that the rate of citations to the article will then reach some lower level, continuing on accumulating citations at (...) some regular but unimpressive rate. Drawing on data covering the period from 1962 to 2019, I show that Menard was close with respect to the first prediction. But I also show that things are less clear with respect to the second prediction. I explain why the data are less clear with respect to the second prediction. (shrink)

This paper spells out the attention schema theory of consciousness in terms of the predictive processing framework. As it stands, the attention schema theory lacks a plausible computational formalization that could be used for developing possible mechanistic models of how it is realized in the brain. The predictive processing framework, on the other hand, fails to provide a plausible explanation of the subjective quality or the phenomenal aspect of conscious experience. The aim of this work is to apply the formal (...) tools of predictive processing to outline a possible model of cognition that details a plausible way in which organisms may acquire or construct the kinds of schemas postulated by the attention schema theory. This is done in terms of Bayesian control models, which tend to favour representing information in a frugal or 'sparse' manner that strips away detail in precisely the way that the attention schema requires. Once integrated, these two accounts can offer a plausible explanation of the supposedly irreducible and mysterious 'feel' of conscious experience, in terms of the frugal manner in which perceptual mechanisms are represented by the attention schema.

This paper attempts to argue for the theory-ladenness of evidence. It does so by employing and analysing an episode from the history of eighteenth century chemistry. It delineates attempts by Joseph Priestley and Antoine Lavoisier to construct entirely different kinds of evidence for and against a particular hypothesis from a set of agreed upon observations or (raw) data. Based on an augmented version of a distinction, drawn by J. Bogen and J. Woodward, between data and phenomena it is shown that (...) the role of theoretical auxiliary assumptions is very important in constructing evidence for (or against) a theory from observation or (raw) data. In revolutionary situations, rival groups hold radically different theories and theoretical auxiliary assumptions. These are employed to construct very different evidence from the agreed upon set of observations or (raw) data. Hence, theory resolution becomes difficult. It is argued that evidence construction is a multi-layered exercise and can be disputed at any level. What counts as unproblematic observation or (raw) data at one level may become problematic at another level. The contingency of these constructions and the (un)problematic nature of evidence are shown to be partially dependent upon the scientific knowledge that the scientific community possesses. (shrink)

This book provides a defence of epistemological relativism against its most powerful opponents.

In this article I caution that María Lugones's critiques of Kimberlé Crenshaw's intersectional theory posit a dangerous form of epistemic erasure, which underlies Lugones's decolonial methodology. This essay serves as a critical engagement with Lugones's essay “Radical Multiculturalism and Women of Color Feminisms” in order to uncover the decolonial lens within Crenshaw's theory of intersectionality. In her assertion that intersectionality is a “white bourgeois feminism colluding with the oppression of Women of Color,” Lugones precludes any possibility of intersectionality operating as (...) a decolonial method. Although Lugones states that her “decolonial feminism” is for all women of color, it ultimately excludes Black women, particularly with her misconstruing of Crenshaw's articulation of intersectionality that is rooted within the Black American feminist tradition. I explore Lugones's claims by juxtaposing her rendering of intersectionality with Crenshaw's and conclude that Lugones's decolonial theory risks erasing Black women from her framework. (shrink)
