We examined two aspects of temperamental approach in early infancy, positive reactivity and anger, and their unique and combined influences on maternal reports of child surgency and attention focusing at 4 years of age. One hundred and fourteen infants were observed for their positive reactions to novel stimuli at 4 months, and their anger expressions during arm restraint at 9 months. Child surgency and attention focusing at age 4 years were assessed by maternal report. Infants who expressed more anger to restraint were rated higher in surgency during early childhood relative to infants who expressed less anger. The effects of positive reactivity to novelty on attention focusing were moderated by anger to restraint. These findings suggest that infant temperamental approach tendencies are multifaceted and have both unique and combined influences on later maternal report of attention and social behavior. 相似文献

Common methods used in the literature to identify factors within exploratory factor analysis have been shown to be potentially problematic. This brief report illustrates a state of the art approach in identifying factor structure by adding parallel analysis before exploratory factor analysis. Parallel analysis enables researchers to have a high degree of confidence of the number of factors to extract before exploratory factor analysis. The procedure is illustrated by using items from the National Survey of Families and Households used to identify relationship scales. 相似文献

A simple formula is proposed for estimating the number of people who have ever lived. Using assumptions that seem reasonable, an estimate of 69 billion (1960) is obtained. The present world population is about 4 percent of this number. 相似文献

Most people with arthritis are not regularly active. Understanding what factors influence exercise is essential for designing programs to increase participation. The objective of this study was to examine the correlates of exercise in people with arthritis. Using a cross-sectional design, sociodemographic, health-related, and psychosocial variables were collected from community-dwelling individuals with arthritis (N = 141). Associations with exercise level were examined with bivariate statistics (ANOVAs, chi-squares) and logistic-regression analyses. Exercisers were less likely than nonexercisers and insufficiently active people to report that arthritis negatively affected their physical and social functioning, and they reported more positive affect and greater self-efficacy (p < .05). Exercisers also reported less pain than nonexercisers (p < .05). In multiple logistic-regression analyses, self-efficacy and physical limitations remained independent predictors of exercise. The results suggest the need to target exercise self-efficacy when designing exercise interventions. Results also suggest the need to tailor exercise programs to individuals' physical limitations. 相似文献

Universities, as with other workplaces, experience problems related to alcohol and other drug use by staff and students. There is little published information about the prevalence of these problems among students in the university setting in Australia as compared with the availability of information from the USA. Curtin University of Technology's experience with alcohol-related problems seems to be documented better than most other Australian institutions, and the available evidence indicates that the level of student alcohol consumption and reported alcohol-related problems is cause for concern. However, this is not to say that Curtin's problems may be any greater than those of any other Australian university with alcohol available on the premises. Many years of involvement in health promotion teaching and research, combined with identification of alcohol and drug related problems on campus, were thought to be the primary factors preceding the university's decision to begin the process of formulating comprehensive alcohol and other drug policy for staff and students. The absence of clear and consistent alcohol and other drug policy can lead to 1) undermining of the educational environment, 2) confusion about appropriate behaviour, 3) dealing with drug-related problems by inaction or arbitrary and inappropriate action. Alcohol and other drug policy has two main goals: problem reduction and better management of problems. 相似文献

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders. 相似文献

In this meta-analysis, correlations of personality traits and career decision-making self-efficacy with self and environmental career exploration were estimated across 71 samples and a pairwise sample of 19,846. Traits included the Big Five personality traits, shyness, locus of control, vocational decision styles, and stress. Many measures of career exploration were based on scores of self and environmental exploration on the Career Exploration Survey. Results varied by characteristics with the largest effects for locus of control, vocational decision style: thinking-feeling and self-efficacy. Environmental exploration and self-exploration were moderately correlated and demonstrated different relations with traits that were consistent with theory. Self-exploration was related to openness to experience and unrelated to extraversion, while environmental exploration was correlated with extraversion. Both were similarly correlated with conscientiousness such that conscientious individuals were more likely to engage in career exploration. 相似文献

The final test of any management decision is its effect on the value of the firm's securities. This paper examines the subsequent impact of the publication of new product announcements on stock returns. A distinguishing feature of this presentation is the integration of decision making in the marketing and finance functional areas. 相似文献
