The authors recruited college students (N = 648) and investigated relationships among academic and social self–efficacy, relational aggression from parents and peers, and nonsuicidal self–injury (NSSI). Results indicated that both types of self–efficacy were related inversely to NSSI. Academic self–efficacy mediated the relationship between parental emotional abuse and NSSI, whereas social self–efficacy mediated the relationship between peer victimization and NSSI. Clinical implications of these findings for college counselors are discussed. 相似文献

In this article, we describe the peer-response workshop we conducted in an ethnically and linguistically diverse secondary school classroom in an urban center in the southwest. We show how the three main parts of the workshop combine to help students cultivate writing relationships in which they see writing as social and co-constructed, rather than as a solitary act performed for the teacher. 相似文献

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended. 相似文献

In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students’ learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in which 60 definite articles (e.g., “the eye”) were replaced with 60 second-person possessive pronouns (e.g., “your eye”). Afterwards, participants answered comprehension and transfer questions. One week later, the participants were asked to restudy the text and to answer the same questions again with the aim to improve their performance. In the personalized text condition, students showed higher transfer performance, spent more time on restudying the text, and reported being more motivated than students in the standard text condition. However, only duration of restudying (not self-reported motivation) mediated the effect of personalization on transfer performance. 相似文献

Content-only queries in hierarchically structured documents should retrieve the most specific document nodes which are exhaustive
to the information need. For this problem, we investigate two methods of augmentation, which both yield high retrieval quality.
As retrieval effectiveness, we consider the ratio of retrieval quality and response time; thus, fast approximations to the
'correct' retrieval result may yield higher effectiveness. We present a classification scheme for algorithms addressing this
issue, and adopt known algorithms from standard document retrieval for XML retrieval. As a new strategy, we propose incremental-interruptible retrieval, which allows for instant presentation of the top ranking documents. We develop a new algorithm implementing this strategy
and evaluate the different methods with the INEX collection. 相似文献

Sport and physical activity are attributed with a positive influence on stress induced complaints due to their overall positive effect on health. The buffering effect on stress has not yet been clearly shown and the findings are inhomogeneous. The following article examines the buffering effect of sport and physical activity on different types of psychological and physical complaints. Therefore, a study was conducted questioning 453 people (M?=?53.56 years; SD?=?11.31) about chronic stress (Perceived Stress Scale), physical complaints (Gießener Beschwerdebogen) and their subjective physical activities (Energy consumption through physical activity – e.g. Soccer or Jogging) and energy consumption – daily bike and walking activity). A buffering effect on nearly all types of complaints could be shown through physical activity, but not through lifestyle activities. Physical activity acts complaint reducing on people suffering from increased stress. A more differentiated examination of the physical activity behaviour, the stress perception and the type of complaints might contribute to clearer findings. 相似文献
