This target article draws together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands. First, during natural movement, feedback from muscle, joint, and cutaneous afferents changes; in human subjects these changes have reflex and kinesthetic consequences. Recent psychophysical and microneurographic evidence suggests that joint and even cutaneous afferents may have a proprioceptive role. Second, the role of centrally generated motor commands in the control of normal movements and movements (...) following acute and chronic deafferentation is reviewed. There is increasing evidence that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement; deficits in motor performance arise when the reliance on proprioceptive feedback is abolished either experimentally or because of pathology. During natural movement, the CNS appears to have access to functionally useful input from a range of peripheral receptors as well as from internally generated command signals. The unanswered questions that remain suggest a number of avenues for further research. (shrink)

The book analyzes how one might philosophize about some of the most difficult and controversial issues in ethics and politics without abandoning either the demands of rigor or the joys of clear vistas.

Unlike its predecessors, this systematic survey of the law of Athens is based on explicit discussion of how the subject might be studies, incorporating topics such as the democratic political system and social structure. Technical and legal terms are explained in a comprehensive glossary.

Objectives: This study aimed to determine attitudinal and self reported behavioural variations between medical students in different years to scenarios involving academic misconduct.Design: A cross-sectional study where students were given an anonymous questionnaire that asked about their attitudes to 14 scenarios describing a fictitious student engaging in acts of academic misconduct and asked them to report their own potential behaviour.Setting: Dundee Medical School.Participants: Undergraduate medical students from all five years of the course.Method: Questionnaire survey.Main measurements: Differences in medical students’ attitudes (...) to the 14 scenarios and their reported potential behaviour with regards to the scenarios in each of the years.Results: For most of the scenarios there was no significant difference in the response between the years. Significant differences in the responses were found for some of the scenarios across the years, where a larger proportion of year one students regarded the scenario as wrong and would not engage in the behaviour, compared to other years. These scenarios included forging signatures, resubmitting work already completed for another part of the course, and falsifying patient information.Conclusion: Observed differences between the years for some scenarios may reflect a change in students’ attitudes and behaviour as they progress though the course. The results may be influenced by the educational experience of the students, both in terms of the learning environment and assessment methods used. These differences may draw attention to the potential but unintentional pressures placed on medical students to engage in academic misconduct. The importance of developing strategies to engender appropriate attitudes and behaviours at the undergraduate level must be recognised. (shrink)

This paper summarizes the longstanding debate over psychology's fragmentation by illustrating two principal impediments to the fostering of consensus and unity. The paper then discusses the important benefits of past dialogue concerning these issues, suggesting that some progress has been made in dealing with problems of disunity and fragmentation, particularly at the metatheoretical and philosophical levels. This general discussion then forms the backdrop for the following articles, which together form a single argument in favor of a hermeneutic approach to the (...) problem of fragmentation. (shrink)
