Predictable somatosensory feedback leads to a reduction in tactile sensitivity. This phenomenon, called tactile suppression, relies on a mechanism that uses an efference copy of motor commands to help select relevant aspects of incoming sensory signals. We investigated whether tactile suppression is modulated by the task-relevancy of the predicted consequences of movement and the intensity of related somatosensory feedback signals. Participants reached to a target region in the air in front of a screen; visual or tactile feedback indicated the reach (...) was successful. Furthermore, tactile feedback intensity varied across two groups of participants. We measured tactile suppression by comparing detection thresholds for a probing vibration applied to the finger either early or late during reach and at rest. As expected, we found an overall decrease in late-reach suppression, as no touch was involved at the end of the reach. We observed an increase in the degree of tactile suppression when strong tactile feedback was given at the end of the reach, compared to when weak tactile feedback or visual feedback was given. Our results suggest that the extent of tactile suppression can be adapted to different demands of somatosensory processing. Downregulation of this mechanism is invoked only when the consequences of missing a weak movement sequence are severe for the task. The decisive factor for the presence of tactile suppression seems not to be the predicted action effect as such, but the need to detect and process anticipated feedback signals occurring during movement.

BackgroundMedical aid in dying was introduced in Quebec in 2015. Quebec clinical guidelines recommend that MAiD be approached as a last resort when other care options are insufficient; however, the law sets no such requirement. To date, little is known about when and how requests for MAiD are situated in the broader context of decision-making in end-of-life care; the timing of MAiD raises potential ethical issues.MethodsA retrospective chart review of all MAiD requests between December 2015 and June 2017 at two (...) Quebec hospitals and one long-term care centre was conducted to explore the relationship between routine end-of-life care practices and the timing of MAiD requests.ResultsOf 80 patients requesting MAiD, 54% received the intervention. The median number of days between the request for MAiD and the patient’s death was 6 days. The majority of palliative care consults came less than 7 days prior to the MAiD request and in another 25% of cases occurred the day of or after MAiD was requested. 35% of patients had no level of intervention form, or it was documented as 1 or 2 at the time of the MAiD request and 19% were receiving life-prolonging interventions.InterpretationWe highlight ethical considerations relating to the timing of MAiD requests within the broader context of end-of-life care. Whether or not MAiD is conceptualised as morally distinct from other end-of-life options is likely to influence clinicians’ approach to requests for MAiD as well as the ethical importance of our findings. We suggest that in the wake of the 2015 legislation, requests for MAiD have not always appeared to come after an exploration of other options as professional practice guidelines recommend. (shrink)

ABSTRACT:This article outlines the policy context for teachers’ learning and continuing professional development in Scotland and considers this in relation to the perspectives of key informants gained through interview. The analysis draws on a triple-lens conceptual framework and points to some interesting contradictions between the policy text and the expressed aspirations of the interviewees. Current policy and the associated structural arrangements are viewed as broadly positive, but interviewees express concerns that an unintended emphasis on contractual arrangements might inhibit the more (...) transformative elements of professional learning.

The medical model of childbearing assumes that a pregnancy always has the potential to turn into a risky procedure. In order to advocate humanized birth in high risk pregnancy, an important step involves the enlightenment of the professional’s preconceptions on humanized birth in such a situation. The goal of this paper is to identify the professionals’ perception of the potential obstacles and facilitating factors for the implementation of humanized care in high risk pregnancies. Twenty-one midwives, obstetricians, and health administrator professionals (...) from the clinical and academic fields were interviewed in nine different sites in Japan from June through August 2008. The interviews were audio taped, and transcribed with the participants’ consent. Data was subsequently analyzed using content analysis qualitative methods. Professionals concurred with the concept that humanized birth is a changing and promising process, and can often bring normality to the midst of a high obstetric risk situation. No practice guidelines can be theoretically defined for humanized birth in a high risk pregnancy, as there is no conflict between humanized birth and medical intervention in such a situation. Barriers encountered in providing humanized birth in a high risk pregnancy include factors such as: the pressure of being responsible for the safety of the mother and the fetus, lack of the women’s active involvement in the decision making process and the heavy burden of responsibility on the physician’s shoulders, potential legal issues, and finally, the lack of midwifery authority in providing care at high risk pregnancy. The factors that facilitate humanized birth in a high risk include: the sharing of decision making and other various responsibilities between the physicians and the women; being caring; stress management, and the fact that the evolution of a better relationship and communication between the health professional and the patient will lead to a stress-free environment for both. Humanized birth in a high risk pregnancy is something that goes beyond just curing women of their illnesses. It can be considered as a token of caring, and continued support, which positively consolidates the doctor-patient relationship. As yet, it has not been described as a practiced guideline, due to its ever-changing complexities. (shrink)

Fraser highlights an unattractive feature of Mohist ethics: the Mohists, while criticizing their Confucian contemporaries, restrict one’s pursuits to the most basic sorts of goods. Fraser suggests that the Mohists assume the perpetuity of scarce resources, which leads to a commitment to austerity, which in turn leads them to deny a plausible third way between austerity and excess. In their defence, I argue that the Mohists do not assume perpetuity of scarce resources but rather the hedonic treadmill. And (...) instead of begging the question by assuming austerity and then denying a moderate alternative to excess, the Mohists take the hedonic treadmill to preclude a principled stopgap between austerity and excess, leaving austerity as the only acceptable option. Finally, these dynamics illuminate a feature that should make us wary of parallels to Millian utilitarianism: the maximization principle of the latter is absent from Mohism, and this goes hand-in-hand with austerity.

H. B. Smith, Professor of Philosophy at the influential 'Pennsylvania School' was (roughly) a contemporary of C. I. Lewis who was similarly interested in a proper account of 'implication'. His research also led him into the study of modal logic but in a different direction than Lewis was led. His account of modal logic does not lend itself as readily as Lewis' to the received 'possible worlds' semantics, so that the Smith approach was a casualty rather than a beneficiary of (...) the renewed interest in modality. In this essay we present some of the main points of the Smith approach, in a new guise. (shrink)

This volume contains thirteen papers that were presented at the 2017 Annual Meeting of the Canadian Society for History and Philosophy of Mathematics/Société canadienne d’histoire et de philosophie des mathématiques, which was held at Ryerson University in Toronto. It showcases rigorously reviewed modern scholarship on an interesting variety of topics in the history and philosophy of mathematics from Ancient Greece to the twentieth century. A series of chapters all set in the eighteenth century consider topics such as John Marsh’s techniques (...) for the computation of decimal fractions, Euler’s efforts to compute the surface area of scalene cones, a little-known work by John Playfair on the practical aspects of mathematics, and Monge’s use of descriptive geometry. After a brief stop in the nineteenth century to consider the culture of research mathematics in 1860s Prussia, the book moves into the twentieth century with an examination of the historical context within which the Axiom of Choice was developed and a paper discussing Anatoly Vlasov’s adaptation of the Boltzmann equation to ionized gases. The remaining chapters deal with the philosophy of twentieth-century mathematics through topics such as an historically informed discussion of finitism and its limits; a reexamination of Mary Leng’s defenses of mathematical fictionalism through an alternative, anti-realist approach to mathematics; and a look at the reasons that mathematicians select specific problems to pursue. Written by leading scholars in the field, these papers are accessible to not only mathematicians and students of the history and philosophy of mathematics, but also anyone with a general interest in mathematics.

This article develops a model of relational happiness that challenges popular individualized definitions and emphasizes how it can enhance the sociological analysis of inequality. Many studies of happiness suggest that social inequalities are closely associated with distributions of happiness at the national level, but happiness research continues to favour individual-level analyses. Limited attention has been given to the intersubjective aspects of happiness and the correlations between it and higher social equality. Conversely, key theoretical debates about inequalities, such as Axel Honneth (...) and Nancy Fraser’s exchanges, have only indirectly touched on happiness. A relational approach to happiness is not new, but what this article offers is a new combination of a relational understanding of happiness as an intersubjectively, culturally experienced complex of emotions with discussions about recognition of marginalized groups and redistribution of material resources. This combined approach can further debates about understanding and remedying social inequalities. It argues that theories and measurements of happiness must consider how it can be achieved collectively through working at mutual respect as well as greater material equality. (shrink)

Un de ces (syntagmes) qui… (à propos de la locution un(e) de ces […] qui) Cet article a pour objet de montrer, sur une question déjà soulevée en stylistique française, ce que nous semble pouvoir apporter la dimension des vastes corpus et des outils logiciels d’exploration assistée. La locution un(e) de ces […] qui, déjà étudiée comme stylème dix-neuviémiste (Bordas), vecteur d’exophore mémorielle (Fraser & Joly), est redéfinie comme support d’un décrochage discursif dans le cadre de la polyphonie du (...) récit (Bakhtine). Elle fait ici l’objet d’un relevé systématique dans un vaste corpus littéraire, qui permet de quantifier les proportions d’une typologie (notamment quant à la concordance aspectuo-temporelle) et d’en affiner la distribution diachronique et par auteurs. On observe alors le fonctionnement de cette locution comme filtre du vocabulaire et l’on montre que non seulement des unités isolées, mais des pôles lexico-thématiques de sa structure polycooccurrentielle (mise en évidence par l’AFC) sont significativement sur et sous-représentés dans les phrases d’emploi. On avance ainsi vers une meilleure connaissance de cette structure-frontière de la langue et du style en français. (shrink)

Developing and implementing artificial intelligence (AI) systems in an ethical manner faces several challenges specific to the kind of technology at hand, including ensuring that decision-making systems making use of machine learning are just, fair, and intelligible, and are aligned with our human values. Given that values vary across cultures, an additional ethical challenge is to ensure that these AI systems are not developed according to some unquestioned but questionable assumption of universal norms but are in fact compatible with the (...) societies in which they operate. This is particularly pertinent for AI research and implementation across Africa, a ground where AI systems are and will be used but also a place with a history of imposition of outside values. In this paper, we thus critically examine one proposal for ensuring that decision-making systems are just, fair, and intelligible—that we adopt a principle of explicability to generate specific recommendations—to assess whether the principle should be adopted in an African research context. We argue that a principle of explicability not only can contribute to responsible and thoughtful development of AI that is sensitive to African interests and values, but can also advance tackling some of the computational challenges in machine learning research. In this way, the motivation for ensuring that a machine learning-based system is just, fair, and intelligible is not only to meet ethical requirements, but also to make effective progress in the field itself.

Reading the Shape of Nature vividly recounts the turbulent early history of the Museum of Comparative Zoology at Harvard and the contrasting careers of its founder Louis Agassiz and his son Alexander. Through the story of this institution and the individuals who formed it, Mary P. Winsor explores the conflicting forces that shaped systematics in the second half of the nineteenth century. Debates over the philosophical foundations of classification, details of taxonomic research, the young institution's financial struggles, and the (...) personalities of the men most deeply involved are all brought to life. In 1859, Louis Agassiz established the Museum of Comparative Zoology to house research on the ideal types that he believed were embodied in all living forms. Agassiz's vision arose from his insistence that the order inherent in the diversity of life reflected divine creation, not organic evolution. But the mortar of the new museum had scarcely dried when Darwin's Origin was published. By Louis Agassiz's death in 1873, even his former students, including his son Alexander, had defected to the evolutionist camp. Alexander, a self-made millionaire, succeeded his father as director and introduced a significantly different agenda for the museum. To trace Louis and Alexander's arguments and the style of science they established at the museum, Winsor uses many fascinating examples that even zoologists may find unfamiliar. The locus of all this activity, the museum building itself, tells its own story through a wonderful series of archival photographs. (shrink)

Mary Warnock steers a clear path through the web of complex issues underlying the use of new reproductive technologies. She begins by analysing what it means to claim something as a 'right', and goes on to discuss the cases of different groups of people. She also examines the ethical problems faced by particular types of assisted reproduction, including artificial insemination, in-vitro fertilization, and surrogacy, and argues that in the future human cloning may well be a viable and acceptable form (...) of treatment for some types of infertility.

What do Albert Einstein and Pablo Picasso have in common? Can we learn about science by studying art? There are many connections just waiting to be discovered between the natural world and artistic techniques that have been used for centuries. Author and retired science educator Mary Kirsch Boehm systematically guides readers through a look at science with an artistic eye, introducing an integrated and often overlooked view of the two disciplines. By exploring the materials and techniques of art and (...) the science behind them, Boehm reveals just how interconnected our world really is. (shrink)

In the Philippines, all transplant centers are mandated by the Department of Health (DOH) to have a Hospital Transplant Ethics Committee (HTEC) to ensure that donations are altruistic, voluntary and free of coercion/commercial transactions. This study was undertaken primarily to describe the organizational and functional profile of existing HTECs and identify areas for improvement. This is a descriptive cross‐sectional study. There was variation in their logistical arrangements (support from hospital, filing systems, office spaces), operations (length and frequency of meetings, number (...) of referrals) and membership (composition, qualifications, occupation, training). The approval rate for donor‐recipient pairs is high with the majority of cases made by living non‐related donors. Appropriate reasons were cited for rejection. The perception of HTECs is that they are competent and confident in their decision‐making. However, there is a need to standardize HTEC composition, provide operating procedures and additional training which can be done by the DOH. (shrink)

Photographer Keithan captures on film the rural landscape's aging and historic barns. But rather than a sad chronicle of America's rural decline, she presents a visual story of endurance and perseverance, of a way of life that continues to thrive. The b&w photographs from each of Michigan's 80 counties are enriched by her narrative, often including histories from the barn owners themselves.

It is with sincere appreciation that I commend this edited collection to readers of the AJTP. The collection meets the task of promoting lively discussion that addresses the interface between theology and philosophy, especially as shaped by empiricist, naturalist, process, and pragmatist traditions. As the most recent volume in the series Toward Ecological Civilization, it delivers papers from the Tenth International Whitehead Conference and Ninth International Forum on Ecological Civilization, held in Claremont, California, June 2015, thereby delivering on a second (...) focus for the AJTP: the development of liberal religious thought in America.The authors gathered in this collection take seriously the earnest and...
