The inconsistent definition of empathy has had a negative impact on both research and practice. The aim of this article is to review and critically appraise a range of definitions of empathy and, through considered analysis, to develop a new conceptualisation. From the examination of 43 discrete definitions, 8 themes relating to the nature of empathy emerged: “distinguishing empathy from other concepts”; “cognitive or affective?”; “congruent or incongruent?”; “subject to other stimuli?”; “self/other distinction or merging?”; “trait or state influences?”; “has (...) a behavioural outcome?”; and “automatic or controlled?” The relevance and validity of each theme is assessed and a new conceptualisation of empathy is offered. The benefits of employing a more consistent and complete definition of empathy are discussed. (shrink)

In recent years, programs for training in research ethics have become widespread, but very little has been done to assess the effectiveness of this training. Because initial studies have failed to demonstrate a positive impact of research ethics training, this project defined two new outcome variables to be tested in a sample of graduate students at the University of California, San Diego. Trainees were surveyed to assess the role of ethics training in altering their perceptions about their own standards, or (...) their knowledge of options available to them if faced with ethical problems that might arise in conducting and reporting research. In response to a mailing of 505 anonymous questionnaires, 283 replies were received. Similar to previous studies, perceptions of standards were not significantly affected by hours spent in informal discussions about research ethics, in attending courses on research ethics, or in discussions of case studies. However, self-reported knowledge of options for facing research ethics problems was significantly increased in association with increased hours of discussion, class time, or case study discussion. Taken together, this study emphasizes the need for increased attention to the definition and assessment of the goals of research ethics training. (shrink)

Decades of research have focused on children's reasoning about math equivalence problems for both practical and theoretical insights. Not only are math equivalence problems foundational in arithmetic and algebra, they also represent a class of problems on which children's thinking is resistant to change. Feedback is one instructional tool that can serve as a key trigger of cognitive change. In this paper, we review all experimental studies on the effects of feedback on children's understanding of math equivalence. Meta-analytic results indicate (...) that feedback has positive effects for low-knowledge learners and negative effects for high-knowledge learners, and these effects are stronger for procedural outcomes than conceptual outcomes. Findings highlight the variable influences of feedback on math equivalence understanding and suggest that models of thinking and reasoning need to consider learner characteristics, learning outcomes, and learning materials, as well as the dynamic interactions among them.

Over the last few years, policies have been introduced in the UK that identify and treat patients as potential organ donors before death. Patients incapacitated due to catastrophic brain injury may now undergo intensive ante-mortem interventions to improve the chances of successfully transplanting their organs into third parties after death. The most significant ethical and legal problem with these policies is that they are not based on the individual’s specific wishes in the circumstances. Policy-makers appear reluctant to inform potential registrants (...) on the Organ Donor Register about ante-mortem donor optimisation procedures and to provide an opportunity to record specific wishes in advance. They are reliant on blind trust in the organ donation programme, which as I argue in this paper, presents significant risks for the achievement of its aim of securing an adequate supply of organs for transplantation. I argue that informed trust, based on accurate information about the future consequences of registra... (shrink)

E. A. Burtt, dans Metaphysical foundations of modern physic remarque que, «dans toutes les études génétiques qui sont entreprises aujourd’hui avec une telle confiance, la nature précise et les assomptions de la pensée scientifique moderne elle-même n’ont jamais fait l’objet d’une recherche critique réellement désintéressée ». Si cela est vrai dans la science moderne, c’est surtout vrai dans la philosophie moderne. Demander quels sont les postulats d’un système quelconque est devenu une question habituelle, depuis que les mathématiques modernes ont mis (...) en question la vérité des postulats d’Euclide et que la logique moderne en a fait ensuite autant de ceux d’Aristote. On recherche ici quels sont les postulats fondamentaux des systèmes cartésiens. (shrink)
