Friends' influence on achievement‐related choices in female adolescents was investigated using the Thematic Apperception Test (H. Murray, 1943), in the context of self‐in‐relation theory (J. V. Jordon, A. G. Kaplan, J. B. Miller, I. P. Stiver, & J. L. Surrey, 1991). Two hypotheses were tested: (1) Achievement‐related stimuli will elicit stories with more unfavorable and conflicted outcomes than will affiliation stimuli; (2) Thematic representation of achievement will be more homogeneous in more highly cohesive peer groups. A multivariate analysis of variance with repeated measures yielded significant results for Hypothesis 1. Thematic analysis of stories supported Hypothesis 2, showing peer group influence on achievement strivings in female adolescents.  相似文献

This work was designed to investigate individual differences in brain electrical activity during a looking version of the A‐not‐B task. It was proposed that this spatial task required the cognitive skills of working memory and inhibitory control, each associated with frontal lobe function. Electroencephalograms (EEGs) were recorded from 54 8‐month‐old infants during baseline and task. Only high performers on the looking task exhibited increases in 6‐ to 9‐Hz EEG power from baseline to task. These task‐related changes were evident at frontal and posterior scalp locations. High performers on the looking task exhibited lower EEG coherence values at right hemisphere frontal locations relative to the low performers. These lower coherence values were evident during baseline and task. All infants showed increased frontal‐parietal coherence during the spatial working memory task relative to baseline values. These data confirm previous cognitive neuroscience work associating frontal lobe function with cognitive performance levels during infancy.  相似文献

The need for appropriate, timely, and increasingly comprehensive career development and education programs continues to escalate. It is interesting that despite the differences in cultures, religions, economies, political systems, and education structures, many countries face similar challenges when designing and implementing career development programs. Sharing and adapting career development interventions and techniques cross‐culturally appear to be viable strategies for implementing or enhancing programs, provided the concepts and materials are tailored to the countries' unique requirements.  相似文献

This paper explores the interrelationship between agricultural policies and development by means of a dynamically recursive, computable general equilibrium model applied to Sri Lanka. The agricultural policies investigated include elimination of the food subsidy, land reform, and technical change in agriculture. The goals considered are the levels and growth rates of GNP and employment, the distribution of income, and the real income level of the lowest income group. The study provides a quantitative assessment of the association between policies and goals and identifies the key economic mechanisms in this association.  相似文献

This article focuses on family social networks and the community of caregivers of neglected children. If neglect is part of family functioning, who watches over the children? Using a case study approach, this study researched 12 children and their parents. Several concepts, such as multiple caregiving and kin keepers, revealed that study children were cared for by many people. Social network mapping used in this study indicated that families were not isolated from the larger community, had various forms of negative and positive social support, were low income, and were involved in substance abuse and domestic violence. Understanding the patterns that emerge from the complex web of family, friends, social service agencies, and the larger social community in which neglected children live can result in better community building.  相似文献

Given the weaker ties to community as noted by scholars such as Robert Putnam, survey researchers should not be surprised by a decline in survey participation over the past 10 years. This research analyzes the use of incentives coupled with introductory themes emphasizing cooperation and helpfulness--cooperative norms in American society--to understand their effects on survey response. This article analyzes two separate experiments (one phone and one mail) that provide evidence that norms of cooperation matter in the decision to participate in a survey, suggesting that this is particularly true at the refusal conversion stage. These results indicate that survey researchers may use such themes to their advantage, especially when conducting a nonresponse follow-up in a mail survey.  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
