Using a sample of 556 adolescents from a suburban community, patterns of various adolescent problem behaviors (e.g., delinquent
behavior, smoking, use of alcohol or drugs) and their links to self-efficacy, social competence, and life events were examined.
Cluster analysis was conducted to identify four subgroups of adolescents who showed distinct patterns of problem behaviors.
These clusters were compared on the measures of self-efficacy, social competence, and life events. Overall results suggest
there are meaningful links between adolescents’ problem behavior patterns and self-efficacy, the amount and quality of participation
in various after school activities, and life events. For example, a subgroup of adolescents who showed uniformly low prevalence
of all problem behaviors reported more positive academic self-efficacy, more active participation in sports and nonsports
activities, more positive life events, and fewer negative events than adolescents who were involved in multiple problem behaviors.
Implications for prevention and future research on adolescent problem behaviors are discussed. 相似文献

The space-time accuracy of an elbow flexion movement task was examined in two experiments over a range of motion extents (1 degrees through 100 degrees ) and short-duration movement times (100, 125, 150, and 400 ms). Nonlinear speed-accuracy functions emerged for both spatial and temporal error over all the movement conditions examined. The results showed that the timing error and spatial error had a high degree of complementarity as predicted by a space-time model of the speed-accuracy relation (Hancock & Newell, 1985). The findings confirm that the frame of reference for measuring movement error determines in part the error functions observed. 相似文献

Possible differences in social comparison choices between individualistic and collectivistic cultures and individuals were
explored among a sample of 235 student participants from the United States and China, focusing on self-esteem as a possible
mediating variable. A self-report social comparison measure was developed and factor analyzed. Correlations revealed that
higher collectivism scores were associated with an increased desire to compare in general, an increased desire to make upward
comparisons, and a decreased desire to make downward comparisons. It is speculated that upward self-improvement comparisons
for the sake of the group may be more common for those high in collectivism. 相似文献

When consumers must make a decision but are uncertain of their preferences, they often select a compromise choice. Early studies emphasized the relational properties of choice alternatives and indicated that the middle option, whose attribute values fall between the values of other alternatives, is always the compromise option. More recent studies have suggested that when consumers rate two attributes with the same metrics, the attribute–balance choice whose two attributes have equal ratings, might represent the compromise choice. We propose that the different characteristics of the middle and attribute–balance options—which may be compatible with certain determinants such as information and task formats—might be more salient and affect the relative attractiveness of each option. The results of three experiments confirmed this prediction: the middle option was more attractive in list‐by‐attributes and rejecting conditions, whereas the attribute–balance option was more attractive in list‐by‐alternatives and choosing conditions.

With the rapid growth of the number of netizens in China, the Internet has become one of the most important parts in the lives
of people who not only can get more information on the Internet, but can also express their own views. In other words, the
Internet has also become a part of real-world events. Drawing on a case study about ‘The Boycott of Carrefour’ in China during
the spring of 2008, the paper first discusses the role and functions of new media during the incident. Through analyses of
a story about the culture of labeling others and a conflict between burning a wrong flag in this case, the paper then explores
the capriciousness of Chinese cyberspace. The author proposes an explanation on how the illusion of truth is generated on
the Internet and then influences the events in the real world. The paper concludes that the Internet is not just a simple
technological tool, but it is intertwined with the sociocultural contexts in which it is rooted.

The present study identifies a broad taxonomy of motives underlying the desire to regulate prejudice and assess the impact of motivation to regulate prejudice on levels of explicit and implicit prejudice. Using self-determination theory as the foundation, six forms of motivation to regulate prejudice are proposed. In Study 1 (N = 257), an exploratory factor analysis reveals evidence for the six proposed dimensions. In Study 2 (N = 198), the six-factor taxonomy of motivation to regulate prejudice is further validated using a confirmatory factor analysis, and construct validity is obtained. In Study 3 (N = 62), motivation to regulate prejudice is manipulated before participants complete the Implicit Association Test (IAT) and explicit measures of prejudice. Results reveal that those with highly self-determined regulation of prejudice demonstrate lower implicit and explicit prejudice than their less self-determined counterparts. Results are discussed in terms of an increased understanding of the motivation to control prejudice. 相似文献

We explored how individuals at-risk for HD who have or have not been tested make reproductive decisions and what factors are
involved. We interviewed 21 individuals (8 with and 4 without the mutation, and 9 un-tested) in-depth for 2 hours each. At-risk
individuals faced a difficult series of dilemmas of whether to: get pregnant and deliver, have fetal testing, have pre-implantation
genetic diagnosis, adopt, or have no children. These individuals weighed competing desires and concerns: their own desires
vs. those of spouses vs. broader moral concerns (e.g., to end the disease; and/or follow dictates against abortion) vs. perceptions
of the interests of current or future offspring. Quandaries arose of how much and to whom to feel responsible. Some changed
their perspectives over time (e.g., first “gambling,” then being more cautious). These data have critical implications for
genetic counselors and other health care workers and future research, particularly as more genetic tests become available. 相似文献

This study examined the effects of Web site structures in terms of advertising effectiveness- memory, attitude, and behavioral intentions. The primary research question for this study is, What type of Web site (Web ad) structure is most effective? In the pilot study, we tested the difference between two Web site structures, linear and interactive, in terms of traditional advertising effectiveness. Results from the pilot study did not support our research expectations. However, differences in terms of memory were noted between the two structures. After re-creating the Web site based on subjects' comments, in the final experiment, we examined the differences between the two structures and the moderating role of personality difference on the effects of Web site structure. The results confirm that participants' attitude, memory, and behavioral intentions were affected differently by the different Web site structures. However, some research hypotheses were not supported by the current data. 相似文献

Inadequate housing threatens family stability in communities across the United States. This study reviews emerging evidence on housing interventions in the context of scale‐up for the child welfare system. In child welfare, scale‐up refers to the extent to which fully implemented interventions sustainably alleviate family separations associated with housing instability. It incorporates multiple aspects beyond traditional measures of effectiveness including costs, potential reach, local capacities for implementation, and fit within broader social services. The framework further encompasses everyday circumstances faced by service providers, program administrators, and policymakers who allocate resources under conditions of scarcity and uncertainty. The review of current housing interventions reveals a number of systemic constraints for scale‐up in child welfare. Reliance on rental assistance programs limits capacity to address demand, while current practices that target the most vulnerable families may inadvertently diminish effectiveness of the intervention and increase overall demand. Alternative approaches that focus on homelessness prevention and early intervention must be tested in conjunction with community initiatives to increase accessibility of affordable housing. By examining system performance over time, the scalability framework provides an opportunity for more efficient coordination of housing services within and outside of the child welfare system. 相似文献
