Confronted with numerous scandals, sports organizations are turning to the adoption of ethical codes to attain more ethical behavior. However, the effectiveness of an ethical code as a means to increase ethical behavior remains debated; furthermore, the particular characteristics of a sports context have not yet been taken into account, nor have the different stages of code establishment been considered in evaluation. This article studies the effectiveness, as measured by the Ethical Climate Index, of ethical codes in sports organizations. Moreover, it investigates the effects of the presence, creation, content, implementation, and enforcement of ethical codes on ethical behavior in sports organizations. Our results shed a light on the conditions that need to be in place to install an effective ethical code in sports organizations: a genuine motivation to improve ethical behavior, the involvement of coaches, and the explicit targeting of the management. 相似文献

Asking questions changes behavior: mere measurement effects on frequency of blood donation. 总被引:1,自引:0,他引:1
OBJECTIVE: This research examined the impact of completing a questionnaire about blood donation on subsequent donation behavior among a large sample of experienced blood donors. DESIGN: Participants (N=4672) were randomly assigned to an experimental condition that received a postal questionnaire measuring cognitions about donation or a control condition that did not receive a questionnaire. MAIN OUTCOME MEASURES: Number of registrations at blood drives and number of successful blood donations were assessed using objective records both 6 months and 12 months later. RESULTS: Findings indicated that, compared to control participants, the mean frequency of number of registrations at blood drives among participants in the experimental group was 8.6% greater at 6 months (p<.0.007), and was 6.4% greater at 12 months (p<.035). Significant effects were also observed for successful blood donations at 6 months (p<.001) and 12 months (p<.004). CONCLUSION: These findings provide the first evidence that the mere measurement is relevant to promoting consequential health behaviors. Implications of the research for intervention evaluation are discussed. 相似文献

This case study investigated team cognition in basketball. The focus was on how concerns in a real match situation were shared among teammates and how the sharedness evolved. The activity of five basketball players (M age = 17.60, SD = 0.89) was studied. The data were collected and processed according to a procedure defined for course-of-action analysis (Theureau, 2003). The results indicated that the instances when all the teammates shared the same typical concern were relatively rare, but temporal analysis revealed two kinds of convergence phenomena (simultaneous and progressive). In conclusion, shared understanding emerged within this team as essentially “local sharing of understanding.” 相似文献

Postnatal depression (PND) is a common condition that has been extensively researched specifically because of its negative impact on the mother-infant relationship. Psychiatric research has looked at comorbidity of major depressive disorder and found it to be strongly associated with Axis II disorders. This study's principal aim was to investigate whether there is a greater incidence of personality disorder (PD) among a PND population than among a non-PND population at 3 months postpartum. A secondary aim was to define the different types of PD. Depression was assessed with the Montgomery and Asberg Depression Rating Scale (MADRS), and PD was assessed with the Structured Interview for DSM-IV Personality Disorders (SIDP-IV) in 109 women with their 12-week-old infants. Twice as many depressed mothers had PD. The PND group presented a greater number of severe clinical symptoms than the nondepressed group (p < .002). Further research is necessary to reexamine the heterogeneity of PND and reassess its impact on infant development. 相似文献

Post-traumatic stress disorder (PTSD) is often accompanied by memory problems and abnormal brain structure, particularly within the hippocampus. We implemented a cross-species, hippocampal-dependent task--the virtual Morris Water task--to assess hippocampal function in people with PTSD and age-matched controls during functional magnetic resonance imaging (fMRI). Performance on the task was equivalent between the groups. However, when correlating fMRI-derived hippocampal activity during this task with PTSD severity, we observe a -0.84 correlation, indicating that those with reduced hippocampal activity show more severe PTSD symptoms. This correlation is not explained by differences in task performance, IQ, duration since trauma, nor time with PTSD. Hence, PTSD severity is predicted by functionally assessing the hippocampus using the virtual Morris water task, suggesting that this task may be used to identify those at risk for developing PTSD following a trauma. 相似文献

In two experiments, 5-, 7-, 9-, and 11-year-old children and college students were presented on each trial with a sentence followed by a probe word. Their task was to indicate whether the probe was in the sentence or not. Of primary interest were the false recognitions and the correct latencies that occurred when the probe word was a synonym or antonym of one of the words in the sentence (Experiment I) or when the probe was a subordinate, superordinate, part, or whole (Experiment II). The younger children were more affected by synonymy than antonymy, although the older children and adults were not. At all ages, the categorical relationships caused more recognition confusion than the partwhole relationships. Subjects were more affected when the probe was a superordinate than when it was a subordinate, and somewhat more affected when the probe was the whole than when it was the part. These results suggest that children as young as 5 years of age have well-organized conceptual systems based on shared meaning components. 相似文献

Dynamical implication of anatomical and mechanical parameters in gait initiation process in children
This study analyses the incidence of anatomical (mass, height, inertia) and mechanical (gravity) parameters on the duration of gait initiation, from a standing posture, in children. Twenty-one children, aged 4, 6 and 8 years, participated in the study. Experimental and theoretical values of the duration of gait initiation are compared. The experimental data are computed from children's gait executed on a force plate. The theoretical data are computed by using an inverted-pendulum model. The results show that (1) duration of gait initiation is independent of gait velocity, as it is in adults; (2) the experimental values are very close to the theoretical values. These findings suggest that children's biomechanical constants are determining factors for initiating movement. It is hypothesized that the capacity to combine and adapt properties of the body with dynamics of the context is acquired through practice of independent walking. 相似文献
