Three experiments explore the role of working memory in motor skill acquisition and performance. Traditional theories postulate that skill acquisition proceeds through stages of knowing, which are initially declarative but later procedural. The reported experiments challenge that view and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory, whereas, the latter does. The behaviour of these two processes was manipulated (...) by providing or withholding visual (and auditory) appraisal of outcome feedback. Withholding feedback was predicted to inhibit the use of working memory to appraise success and, thus, prevent the formation of declarative knowledge without affecting the accumulation of procedural knowledge. While the first experiment failed to support these predictions, the second and third experiments demonstrated that procedural and declarative knowledge can be acquired independently. It is suggested that the availability of working memory is crucial to motor performance only when the learner has come to rely on its use. (shrink)

"O'Meara masterfully situates Pryzwara in relation to the traditional and contemporary theological, philosophical, ecclesial, cultural, and social contexts within which he wrote." --_William P. Loewe, professor of religious studies, Catholic University of America_ Erich Przywara, S.J. is one of the important Catholic intellectuals of the twentieth century. Yet, in the English-speaking world Przywara remains largely unknown. Few of his sixty books or six hundred articles have been translated. In this engaging new book, Thomas O'Meara offers a comprehensive study of the (...) German Jesuit Erich Przywara and his philosophical theology. Przywara's scholarly contributions were remarkable. He was one of three theologians who introduced the writings of John Henry Cardinal Newman into Germany. From his position at the Jesuit journal in Munich, _Stimmen der Zeit_, he offered an open and broad Catholic perspective on the cultural, philosophical, and theological currents of his time. As one of the first Catholic intellectuals to employ the phenomenologies of Edmund Husserl and Max Scheler, he was also responsible for giving an influential, more theological interpretation of the Spiritual Exercises of Ignatius Loyola. Przywara was also deeply engaged in the ideas and authors of his times. He was the first Catholic dialogue partner of Karl Barth and Paul Tillich. Edmund Husserl was counted among Przywara's friends, and Edith Stein was a close personal and intellectual companion. Through his interactions with important figures of his age and his writings, ranging from speculative systems to liturgical hymns, Przywara was of marked importance in furthering a varied dialogue between German Catholicism and modern culture. Following a foreword by Michael Fahey, S.J., O'Meara presents a chapter on Pryzwara's life and a chronology of his writings. O'Meara then discusses Pryzwara's philosophical theology, his lecture-courses at German universities on Augustine and Aquinas, his philosophy of religion, and his influence on important intellectual contemporaries. O'Meara concludes with an in-depth analysis of Pryzwara's theology, focusing particularly on his Catholic views of person, liturgy, and church. (shrink)

Background: Nursing students on clinical placements as part of their professional training are routinely faced with situations involving ethical conflicts. The initial act of perceiving a situation as causing an ethical dilemma is the result of both the students’ personal values, drawn from their culture and families, and of the professional knowledge and values that they have acquired through training and experience. Objectives: Nursing students’ experiences on clinical placements in primary care settings were investigated in order to identify situations that (...) they perceived as involving ethical conflict and describe the elements they took into consideration during their decision-making processes in these situations. Methods: The research design was qualitative descriptive case study. Around 50 students from three different intakes to a nursing degree answered a questionnaire and discussed it in focus groups. Ethical considerations: The study was designed in accordance with the principles guiding research with human beings and was approved by the Human Research Ethics Committee. Results: Synthesised into two principal axes: (a) ethical conflicts in primary care, linked with the domains of working processes, professional nursing ethics and human and social rights and (b) students’ decision-making processes – realisation, reflection and intervention. Conclusion: The student nurses saw themselves both as actors and spectators in situations involving ethical problems and demanding moral deliberation, demonstrating the ability to base their arguments soundly. They tended to emphasise the possibilities offered by dialogue and that different ethical values must be respected to find fair solutions to ethical problems. (shrink)

This paper consists of three main parts. First, we give an introduction to Hill’s assumption A (n) and to theory of interval probability, and an overview of recently developed theory and methods for nonparametric predictive inference (NPI), which is based on A (n) and uses interval probability to quantify uncertainty. Thereafter, we illustrate NPI by introducing a variation to the assumption A (n), suitable for inference based on circular data, with applications to several data sets from the literature. This includes (...) attention to comparison of two groups of circular data, and to grouped data. We briefly discuss such inference for multiple future observations. We end the paper with a discussion of NPI and objective Bayesianism. (shrink)

Shepherdson [14] showed that for a discrete ordered ring I, I is a model of IOpen iff I is an integer part of a real closed ordered field. In this paper, we consider integer parts satisfying PA. We show that if a real closed ordered field R has an integer part I that is a nonstandard model of PA (or even IΣ₄), then R must be recursively saturated. In particular, the real closure of I, RC (I), is recursively saturated. We (...) also show that if R is a countable recursively saturated real closed ordered field, then there is an integer part I such that R = RC(I) and I is a nonstandard model of PA. (shrink)

ABSTRACT:A wide range of research uses patterns of genetic variation to infer genetic similarity between individuals, typically referred to as genetic ancestry. This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications. This essay presents an ethics framework in the spirit of virtue ethics for these researchers: rather than focus on (...) rule following, the framework is designed to build researchers’ capacities to react to the ethical dimensions of their work. The authors identify one overarching principle of intellectual freedom and responsibility, noting that freedom in all its guises comes with responsibility, and they identify and define four principles that collectively uphold researchers’ intellectual responsibility: truthfulness, justice and fairness, anti-racism, and public beneficence. Researchers should bring their practices into alignment with these principles, and to aid this, the authors name three common ways research practices infringe these principles, suggest a step-by-step process for aligning research choices with the principles, provide rules of thumb for achieving alignment, and give a worked case. The essay concludes by identifying support needed by researchers to act in accord with the proposed framework. (shrink)

Background Regarding controversial medical services, many have argued that if physicians cannot in good conscience provide a legal medical intervention for which a patient is a candidate, they should refer the requesting patient to an accommodating provider. This study examines what US physicians think a doctor is obligated to do when the doctor thinks it would be immoral to provide a referral. Method The authors conducted a cross-sectional survey of a random sample of 2000 US physicians from all specialties. The (...) primary criterion variable was agreement that physicians have a professional obligation to refer patients for all legal medical services for which the patients are candidates, even if the physician believes that such a referral is immoral. Results Of 1895 eligible physicians, 1032 (55%) responded. 57% of physicians agreed that doctors must refer patients regardless of whether or not the doctor believes the referral itself is immoral. Holding this opinion was independently associated with being more theologically pluralistic, describing oneself as sociopolitically liberal, and indicating that respect for patient autonomy is the most important bioethical principle in one's practice (multivariable ORs, 1.6–2.4). Conclusions Physicians are divided about a professional obligation to refer when the physician believes that referral itself is immoral. These data suggest there is no uncontroversial way to resolve conflicts posed when patients request interventions that their physicians cannot in good conscience provide. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Edmund Burke was one of the most profound, versatile, and accomplished thinkers of the eighteenth century. Born and educated in Dublin, he moved to London to study law, but remained to make a career in English politics, completing A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful before entering the political arena. A Member of Parliament for nearly thirty years, his speeches are still read and studied as classics of political thought, and through his best-known (...) work, Reflections on the Revolution in France he has continued to exercise a posthumous influence as `the father of conservatism'. This is the first full, scholarly biography of Burke for over a generation, to be completed in two volumes. The first volume covers the years between 1730-1784, and describes his Irish upbringing and education, early writing, and his parliamentary career throughout the momentous years of the American War of Independence. Lavishly illustrated, it provides an authoritative account of the complexity and breadth of Burke's philosophical and political writing and examines its origins in his personal experiences and the political world of his day. This outstanding book will be be required reading for anybody seeking a fuller understanding of eighteenth-century history, philosophy, and political thought. (shrink)

This book contributes to the philosophy of mind by finding a middle ground for analysis in the work of art, understood not merely as a thing but as a concrete manifestation of an individual mind. In the other direction aesthetic theory is sharpened by applying the categories of mind in explaining the structure found in a work of art. The book is made up of essays on such differing topics as drawing an object, the mind’s image of itself, expression, the (...) art lesson, illusion, symbolism, and discussions of the thinkers T. S. Eliot, F. H. Bradley, and R. G. Collingwood. And the various topics are treated as separate issues, though each exemplifies Wollheim’s thesis that there is not one basic problem to be explained in art or in the philosophy of mind. (shrink)

Many studies related to religious and sports issues have been carried out. However, there are limited studies, especially those related to religiosity, anxiety and life satisfaction. To cope with this situation, this study aims to: (1) assess the religiosity, anxiety and life satisfaction of athletes; (2) determine the role of gender and the type of sport in those constructs and (3) establish the correlations between the constructs. The study involved 244 elite athletes from Papua province of Indonesia, with an average (...) age of 22.2 years. The athletes were from a variety of sports, either individual or team sports. The religiosity, anxiety and life satisfaction were measured using Spirituality in Sports Test (SIST), Sport Anxiety Scale-2 (SAS-2) and Satisfaction with Life Scale (SWLS), respectively. One-way analysis of variance (ANOVA) was used to assess the association between explanatory variables (gender and type of sport) and all those three constructs. Path analysis was used to determine the correlations between the constructs. This study’s data suggested that both gender and the type of sport are associated significantly with the level of anxiety and life satisfaction of athletes but not with athlete religiosity. There is a strong and direct effect of religiosity on anxiety and on the happiness in life (life satisfaction). The higher the level of religiosity of the athletes, the happier their life is perceived and the lower the level of the anxiety. In conclusion, this study reveals that individual sport athletes and female athletes tend to have higher levels of anxiety and lower life satisfaction. In addition, religiosity has a direct effect on anxiety and life satisfaction of the athletes. Therefore, religious values might need to be internalised during the training of athletes to reduce the anxiety during the competitions. Contribution: This study provides a new insight into the role of religiosity in anxiety and life satisfaction of athletes. This study also identifies the groups of athletes that are prone to have higher anxiety and therefore should be concerned and targeted. The findings of this study could be used as a complement strategy to increase the athletes’ happiness and to reduce the anxiety during the coaching and training processes in order to be able to achieve targeted results in a competition.
