Existing scholarship on the debates over expertise in mid-nineteenth-century Britain has demonstrated the importance of popular writings on the sciences to definitions of scientific authority. Yet while men of science might position themselves in opposition to the stereotype of the merely popular writer, the self-identity of the popular writer remained ambiguous. This essay examines the careers of William Charles Linnaeus Martin (1798-1864) and Thomas Milner (1808-ca. 1883) and places them in the context of others who made their living by writing works on the sciences for the general reader. Martin wrote on zoology and Milner moved between astronomy, geology, and geography. The essay unravels the close but ambivalent relationship between the professions of authorship and of science and highlights writing as another aspect of scientific practice. Both writers were moderately financially successful, but Martin's sense of failure and Milner's satisfaction reflect their contrasting images of their professional identity.  相似文献

In the present study, we examined the independent and combined effects of an inspiratory muscle warm-up and inspiratory muscle training on intermittent running to exhaustion. Twelve males were recruited to undertake four experimental trials. Two trials (Trials 1 and 2) preceded either a 4-week training period of 1 × 30 breaths twice daily at 50% (experimental group) or 15% (control group) maximal inspiratory mouth pressure (PImax). A further two trials (Trials 3 and 4) were performed after the 4 weeks. Trials 2 and 4 were preceded by a warm-up: 2 × 30 breaths at 40% PImax. Pre-training PImax and distance covered increased (P < 0.05) similarly between groups after the warm-up (~11% and ~5-7% PImax and distance covered, respectively). After training, PImax increased by 20 ± 6.1% (P < 0.01; d = 3.6) and 26.7 ± 6.3% (P < 0.01; d = 3.1) when training and warm-up were combined in the experimental group. Distance covered increased after training in the experimental group by 12 ± 4.9% (P < 0.01; d = 3.6) and 14.9 ± 4.5% (P < 0.01; d = 2.3) when training and warm-up interventions were combined. In conclusion, inspiratory muscle training and inspiratory muscle warm-up can both increase running distance independently, but the greatest increase is observed when they are combined.  相似文献

Within the self-determination theory (Deci & Ryan, 2000) framework, research has considered the consequences of coaches' autonomy supportive and controlling behaviors on various athlete outcomes (e.g., motivation and performance). The antecedents of such behaviors, however, have received little attention. Coaches (N = 443) from a variety of sports and competitive levels completed a self-report questionnaire to assess their psychological need satisfaction, well-being and perceived interpersonal behaviors toward their athletes. Structural equation modeling demonstrated that coaches' competence and autonomy need satisfaction positively predicted their levels of psychological well-being, as indexed by positive affect and subjective vitality. In turn, coaches' psychological well-being positively predicted their perceived autonomy support toward their athletes, and negatively predicted their perceived controlling behaviors. Overall, the results highlight the importance of coaching contexts that facilitate coaches' psychological need satisfaction and well-being, thereby increasing the likelihood of adaptive coach interpersonal behavior toward athletes.  相似文献

Editor’s Note: A JRAM email symposium is structured in the same way of a convention symposium. A group is empaneled to discuss an issue, a moderator asks the panel to address a series of questions while one or more discussants are tasked with responding to the panelists and acting as a surrogate for the audience in the understanding and the interrogation of the ideas presented. In this symposium, panelists were emailed a list of identical questions by the moderator. Panelists and discussants were selected for their knowledge, experience, and the diversity of ideas they bring to the symposium. The answers were then collated, lightly edited for spelling or syntax, arranged in a readable order, and then emailed to the discussants for their feedback. Follow-up questions were only asked for the purpose of clarity with regard to a definition or a convoluted sentence. Both panelists and discussants were encouraged to respond conversationally to the issues.  相似文献

It is perceived that, during the triathlon or duathlon, cycling with a steep (>76°) rather than a shallow (?76°) frame geometry might attenuate the fatigue associated with progression from the cycle to run disciplines and improve subsequent 10-km running performance. This is based on anecdotal testimony from athletes purporting to have experienced improved performance; no empirical evidence exists. To evaluate this view, eight male triathletes completed a counterbalanced, 40-km cycle ride at two frame geometries (73° and 81°) at ~70% VO 2peak . Immediately after completion of each 40-km cycle, a self-paced 10-km treadmill time trial was undertaken, during which physiological, kinematic and performance variables were measured. The 10-km run performance (mean - s : 42:55 - 4:19 vs 46:15 - 4:52 min; P ? 0.01) and combined cycle and run performance (1:45:49 - 5:45 vs 1:50:33 - 6:08; P ? 0.001) were faster in the 81° than the 73° condition. Improvements in performance were most prominent during the first 5 km of the run (21:41 - 2:15 vs 24:15 - 2:31 min in the 81° and 73° conditions respectively). These improvements were not evident during the second 5 km of the run. No differences in physiological variables were noted, although heart rate, stride length and stride frequency were increased during the 81° condition ( P ? 0.05). Modifying frame geometry from a seat tube angle of 73° to 81° improves 10-km running and combined cycle plus run performance. These improvements in performance might relate to alterations during the cycling phase, which minimizes the 'residual effect' of this (i.e. the adverse changes in substrate availability, thermoregulatory, cardiovascular and biomechanical factors felt immediately after transition from cycling to running) and attenuates negative changes in physiological and kinematic responses during the 10-km run.  相似文献

Truth as Process     
Ian Winchester 《Interchange》2005,36(1-2):209-214
Although Whitehead himself, in Process and Reality, appears to maintain a correspondence theory of truth, at various points he also appears to hold that truth is a function of the process under consideration. This suggestion is considered and developed beyond Whitehead’s few examples. It is suggested that such a theory could be extended further and that it would be consistent with Whitehead’s natural philosophical tendency.  相似文献

With the advent of the ERASMUS programme a new impetus has been given to the exchange of students between countries within the European Community. Having outlined the aims and objectives of ERASMUS, the authors take as a case-study the development of links between the Universities of Birmingham and Grenoble III (Stendhal University), from the initial inter-university agreemart to the creation of an ERASMUS diploma. The problems posed by diffetences in university systems and practices in Britain and France are identified. Academic issues discussed include the relative merits of contrastive and complementay study programmes, the tailoring of course packages to the needs of specific groups of students, linguistic difficulties, assessment and validation procedures. After a brief consideration of practical arrangements, the article concludes with an evaluation of lessons which are to be learnt and of the extent to which such an initiative might be said to fulfil the ideals of the ERASMUS program.  相似文献
