For six weeks, four Suzuki piano students listened for a half hour daily to special recordings of repertoire being learned. Their piano teacher, blind to which pieces had been rendered at normal or at half speed, provided pre- and post-assessments of the performance on a battery of scales. Half-speed renditions resulted in modest facilitation which was discussed in terms of imagery, coding, and covert rehearsal. 相似文献

Aim. This study analysed variations between different regions of the world in diagnosing and treating testosterone (T) deficiency.Methods. Physicians were interviewed in Germany, Spain and the United Kingdom, in Brazil, in Saudi Arabia and South Korea. Items in the survey: 1) reasons/motivation to use or not to use T; 2) what category of patients would not receive T on the basis of these concerns; 3) concerns about prostate pathology in the decision not to provide T treatment; 4) phosphodiesterase type 5 (PDE-5) inhibitors are efficacious, but T treatment makes a comeback.Results. Between 5% and 10% of consulting patients suffered from T deficiency. The fear to induce prostate cancer appeared very powerful. About 68% of physicians associate the use of T more with risks than benefits, more so in Europe than elsewhere. As a result about 35% of hypogonadal men do not receive treatment. The PDE-5 inhibitors are very prominent in the treatment of erectile dysfunction. Of patients suffering from erectile dysfunction, 18% to 29% have T deficiency which is not always diagnosed and treated.Conclusion. World-wide physicians require more education on diagnosing T deficiency, on the role of T in erectile dysfunction and the relative safety of testosterone treatment. 相似文献

Reliable access to dependable, high quality childcare services is a vital concern for large numbers of American families. The childcare industry consists of private nonprofit, private for-profit, and governmental providers that differ along many dimensions, including quality, clientele served, and organizational stability. Nonprofit providers are theorized to provide higher quality services given comparative tax advantages, higher levels of consumer trust, and management by mission driven entrepreneurs. This study examines the influence of ownership structure, defined as nonprofit, for-profit sole proprietors, for-profit companies, and governmental centers, on organizational instability, defined as childcare center closures. Using a cross sectional data set of 15724 childcare licenses in California for 2007, we model the predicted closures of childcare centers as a function of ownership structure as well as center age and capacity. Findings indicate that for small centers (capacity of 30 or less) nonprofits are more likely to close, but for larger centers (capacity 30 +) nonprofits are less likely to close. This suggests that the comparative advantages available for nonprofit organizations may be better utilized by larger centers than by small centers. We consider the implications of our findings for parents, practitioners, and social policy. 相似文献

Abstract Objective: This study investigates the individual, interpersonal, and institutional level factors that are associated with overall mental health among college students. Participants: Data are from an online cross-sectional survey of 2,203 students currently enrolled at a large public university. Methods: Mental health was ascertained using a subcomponent of the RAND Medical Outcomes Study functioning and well-being measures developed by the RAND corporation. Stepwise regression was used to determine if self-reported measures of individual (ie, coping abilities), interpersonal (ie, intergroup awareness), and institutional (ie, campus climate/tension) level factors were associated with overall mental health, after controlling for demographic characteristics. Results: The combined effects of both individual and institutional level measures were associated with student mental health. In particular, limited coping abilities and a perceived racially tense campus climate contributed to the psychological distress of college students. Conclusions: Simultaneously addressing the individual and institutional level influences on mental health offers the most promising help for students. 相似文献

The theoretical analysis of the concepts of social capital and of social cohesion shows that social capital should be considered as a micro concept whereas social cohesion, being a broader concept than social capital, is a more appropriate concept for macro analysis. Therefore, we suggest that data on the individual level should only be used to analyze the relationship between social capital, social cohesion indicators and subjective well-being and that they do not allow commenting on the level of social cohesion in a society. For this last type of analyses aggregated indicators of social cohesion have to be computed which is not the issue of this paper. Our empirical analysis is based on individual data for Luxembourg in 2008. In general, our results suggest that investments in social capital generate monetary returns (increased income) and psychic returns (increased subjective well-being) even in a highly developed and multicultural country like Luxembourg. When we are adding on the micro level variables representing the economic domain of social cohesion following Bernard (1999), then we observe that this domain also has an effect on income and on subjective well-being. Therefore, we recommend including the economic domain in any future analysis using the concept of social cohesion. 相似文献

Simple risk formulas, such as risk = probability × impact, or risk = exposure × probability × consequence, or risk = threat × vulnerability × consequence, are built into many commercial risk management software products deployed in public and private organizations. These formulas, which we call risk indices, together with risk matrices, “heat maps,” and other displays based on them, are widely used in applications such as enterprise risk management (ERM), terrorism risk analysis, and occupational safety. But, how well do they serve to guide allocation of limited risk management resources? This article evaluates and compares different risk indices under simplifying conditions favorable to their use (statistically independent, uniformly distributed values of their components; and noninteracting risk‐reduction opportunities). Compared to an optimal (nonindex) approach, simple indices produce inferior resource allocations that for a given cost may reduce risk by as little as 60% of what the optimal decisions would provide, at least in our simple simulations. This article suggests a better risk reduction per unit cost index that achieves 98–100% of the maximum possible risk reduction on these problems for all budget levels except the smallest, which allow very few risks to be addressed. Substantial gains in risk reduction achieved for resources spent can be obtained on our test problems by using this improved index instead of simpler ones that focus only on relative sizes of risk (or of components of risk) in informing risk management priorities and allocating limited risk management resources. This work suggests the need for risk management tools to explicitly consider costs in prioritization activities, particularly in situations where budget restrictions make careful allocation of resources essential for achieving close‐to‐maximum risk‐reduction benefits. 相似文献
