苏轼在绘画理论方面,首先引起我们注意的,是关于风格的见解.他在评论古今画家作品的时候,曾经提出“新奇”①、“清新”②、“清妍”③、“清雄奇富”④、“天全”⑤、“自然”⑥、“雄深”⑦、“雄妍”⑧、“雄放”⑨、“豪放”⑩,以及“轶妙”⑾、“神俊”⑿、“神妙”⒀等等概念,无疑,这些都是苏轼的审美观点,他凭 相似文献

以语篇重建任务为中心的整体语言教学模式是为克服传统的以传授语言知识为中心的零碎语言教学模式存在的问题而提出的;该模式不仅把英语视为语言知识的载体,更将其视为信息的载体。教师通过任务的提出为先导,以小组为单位组织学生参与围绕语篇解构和重建的听说读写方面的活动,使学生不断地运用目的语获取信息和表达信息,从而产生综合效应,推动语言能力的全面发展。 相似文献

How do schemas about self-salience--the importance of the self versus the collective in social relations--affect mental health? We propose that self-salience shapes the likelihood of experiencing internalizing or externalizing problems. Schemas that privilege others over the self increase the risk of internalizing symptoms, including depressive symptoms and anxiety, whereas those that privilege the self over others predispose individuals to externalizing behaviors of antisocial behavior and substance abuse. Furthermore, we propose that these schemas contribute to the gender differences that exist in these problems. We test these predictions with data from adolescents, the stage at which these problems and the gender differences in them arise. Results show that self-salience underlies both internalizing and externalizing problems. In addition, schemas about self-salience help explain the gender differences found in mental health problems. 相似文献

Personal, health, academic, and environmental predictors of stress for residence hall students 总被引:4,自引:0,他引:4

The authors studied contributors to stress among undergraduate residence hall students at a midwestern, land grant university using a 76-item survey consisting of personal, health, academic, and environmental questions and 1 qualitative question asking what thing stressed them the most. Of 964 students selected at random, 462 (48%) responded to the survey. The authors weighted data to reflect the overall university-wide undergraduate population (55% men, 12% minority or international, and 25% freshmen). Women and US citizens experienced greater stress than did men and non-US citizens, respectively. Frequency of experiencing chronic illness, depression, anxiety disorder, seasonal affective disorder, mononucleosis, and sleep difficulties were significant stress predictors. Although alcohol use was a positive predictor, drug use was a negative predictor of stress. Both a conflict and a satisfactory relationship with a roommate, as well as a conflict with a faculty or staff member, were also significant predictors of stress. 相似文献

Taking an active part and responsibilities in one's own life is not always easy, particularly at adolescence, which is a very important period in which people progressively find their identity and life project. This article describes the social validation analyses of a Belgian self-determination curriculum that was adapted from a French-Canadian curriculum. It was done with the participation of adolescents with intellectual disabilities, teachers, and experts from the field. Overall, results indicate a satisfying to very satisfying appreciation of the social utility of the training manual. The findings also highlighted that the curriculum actually supports the conceptual framework of self-determination. 相似文献

Using the data from the AIDS Link to Intravenous Experiences cohort study as an example, an informative censoring model was
used to characterize the repeated hospitalization process of a group of patients. Under the informative censoring assumption,
the estimators of the baseline rate function and the regression parameters were shown to be related to a latent variable.
Hence, it becomes impractical to directly estimate the unknown quantities in the moments of the estimators for the bandwidth
selection of a smoothing estimator and the construction of confidence intervals, which are respectively based on the asymptotic
mean squared errors and the asymptotic distributions of the estimators. To overcome these difficulties, we develop a random
weighted bootstrap procedure to select appropriate bandwidths and to construct approximated confidence intervals. One can
see that our method is simple and faster to implement from a practical point of view, and is at least as accurate as other
bootstrap methods. In this article, it is shown that the proposed method is useful through the performance of a Monte Carlo
simulation. An application of our procedure is also illustrated by a recurrent event sample of intravenous drug users for
inpatient cares over time. 相似文献

Concerns have been raised regarding the appropriateness of asking about violence victimization in telephone interviews and whether asking such questions increases respondents' distress or risk for harm. However, no large-scale studies have evaluated the impact of asking such questions during a telephone interview. This study explored respondents' reactions to questions regarding violence in two large recently completed telephone surveys. After respondents were asked about violence, they were asked if they thought surveys should ask such questions and whether they felt upset or afraid because of the questions. In both surveys, the majority of respondents (regardless of their victimization history) were willing to answer questions about violence and were not upset or afraid because of the questions. More than 92% of respondents thought such questions should be asked. These results challenge commonly held beliefs and assumptions and provide some assurance to those concerned with the ethical collection of data on violent victimization. 相似文献

To determine sex and race differences in muscle power per unit of muscle contraction, knee-extensor muscle power normalized for knee-extensor muscle volume was measured in 79 middle-aged and older adults (30 men and 49 women, age range 50-85 years). Results revealed that women displayed a 38% faster peak movement velocity than men and African Americans had a 14% lower peak movement velocity than Whites of a similar age when expressed per unit of involved muscle (p < .001). As expected, men exhibited greater knee-extensor strength and peak power per unit of muscle than women, but women had a faster knee- extension movement velocity per unit of muscle than men at the same relative strength level. Moreover, African Americans had greater knee-extensor muscle volume than Whites but exhibited lower knee-extensor strength and lower movement velocity per unit of muscle when tested at the same relative strength levels. 相似文献

The authors describe a medical center-based randomized trial aimed at determining the feasibility and effectiveness of partnering patients and primary-care providers with an exercise health counselor. Study participants included 165 veterans age 70 years and older. The primary end point was change in physical activity at 3 and 6 months comparing patients receiving high-intensity physical activity counseling, attention control counseling, and usual care after receiving standardized clinic-based counseling. We noted a significant Group x Time interaction (p = .041) for physical activity frequency and a similar effect for caloric expenditure (p = .054). Participants receiving high-intensity counseling and usual care increased physical activity over the short term, but those with usual care returned to baseline by the end of the study. The intervention was well received by practitioners and patients. We conclude that partnering primary-care providers with specialized exercise counselors for age- and health-appropriate physical activity counseling is effective. 相似文献
