This investigation proposes that theory of mind (ToM) may be related more strongly to change in friendships than peer acceptance in late middle childhood through early adolescence, and examines the relation between ToM and anxious solitude. Fourth grade ToM was tested as a predictor of change in reciprocated friendships, peer acceptance, and anxious solitude from 4th to 7th grade, and, conversely, reciprocated friendships, peer acceptance, and anxious solitude in 3rd grade were tested as predictors of 4th grade ToM. Gender moderation of these relations was evaluated. Participants were 688 American public-school children (51.5% girls), 193 of whom completed a ToM questionnaire in 4th grade. In 3rd–7th grade children and their peers reported reciprocated friendship, and peers reported peer acceptance and anxious solitude annually. A multi-group (gender split) autoregressive cross-lagged panel analysis modeled relations between ToM and reciprocated friendship, peer acceptance, and anxious solitude over time. Consistent with hypotheses, girls’ more advanced 4th grade ToM predicted incremental gains in their number of friendships two years later, but not their peer acceptance. In contrast, boys’ more advanced 4th grade ToM did not predict change in their number of friendships or peer acceptance over time. Gender differences in the relation between ToM and friendship are discussed in the context of gender-specific peer relations patterns in late middle childhood and early adolescence. Additionally, more advanced 4th grade ToM predicted gains in anxious solitude in middle school for both genders. This somewhat surprising result is discussed in relation to ToM assessment and peer relations in anxious solitary children. 相似文献

The purpose of the current study was to assess staff preference for how data were displayed on graphs. Specifically, preference for line versus bar graphs was assessed, as well as preference for data displayed as one date in time versus multiple dates showing performance trends. A secondary purpose of the study was to assess staff comprehension of the data presented across different graphic displays. Participants included 60 entry-level direct care staff and 25 seasoned therapists. Therapists had more advanced training in applied behavior analysis than the direct care staff. The vast majority of direct care staff preferred data depicted as a bar graph versus data depicted as a line graph, even preferring a single bar graph over a time-series line graph. The therapists preferred time-series line graphs to bar graphs. Most staff demonstrated understanding of the data, regardless of how it was depicted. 相似文献

Employees' expected contributions can be incongruent with those of their leader. We examine the congruence effect of leaders' and employees' expected contributions on job satisfaction. Results of cross-level polynomial regressions on 947 employees and 224 leaders support the congruence effect. When expected contributions are congruent, employees are more satisfied with their job. Our findings suggest that employees enjoy high challenges, as long as these challenges are in harmony with the expected contributions of their leaders. Employees are less satisfied with their jobs both when their expected contributions were higher than their leaders' and when their expected contributions were lower than those of their leaders. Beyond the relevance of having high expected contributions, the findings highlight the crucial role played by the congruence of expected contributions of leaders and employees. 相似文献

To reduce consumer health risks from foodborne diseases that result from improper domestic food handling, consumers need to know how to safely handle food. To realize improvements in public health, it is necessary to develop interventions that match the needs of individual consumers. Successful intervention strategies are therefore contingent on identifying not only the practices that are important for consumer protection, but also barriers that prevent consumers from responding to these interventions. A measure of food safety behavior is needed to assess the effectiveness of different intervention strategies across different groups of consumers. A nationally representative survey was conducted in the Netherlands to determine which practices are likely conducted by which consumers. Participants reported their behaviors with respect to 55 different food-handling practices. The Rasch modeling technique was used to determine a general measure for the likelihood of an average consumer performing each food-handling behavior. Simultaneously, an average performance measure was estimated for each consumer. These two measures can be combined to predict the likelihood that an individual consumer engages in a specific food-handling behavior. A single "food safety" dimension was shown to underlie all items. Some potentially safe practices (e.g., use of meat thermometers) were reported as very difficult, while other safe practices were conducted by respondents more frequently (e.g., washing of fresh fruit and vegetables). A cluster analysis was applied to the resulting data set, and five segments of consumers were identified. Different behaviors may have different effects on microbial growth in food, and thus have different consequences for human health. Once the microbial relevance of the different consumer behaviors has been confirmed by experiments and modeling, the scale developed in the research reported here can be used to develop risk communication targeted to the needs of different consumer groups, as well as to measure the efficacy of different interventions. 相似文献

Consumer Selection of Food-Safety Information Sources 总被引:1,自引:0,他引:1
The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two-thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information-acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies. 相似文献

The Value of Information in Decision‐Analytic Modeling for Malaria Vector Control in East Africa 下载免费PDF全文

Decision analysis tools and mathematical modeling are increasingly emphasized in malaria control programs worldwide to improve resource allocation and address ongoing challenges with sustainability. However, such tools require substantial scientific evidence, which is costly to acquire. The value of information (VOI) has been proposed as a metric for gauging the value of reduced model uncertainty. We apply this concept to an evidenced‐based Malaria Decision Analysis Support Tool (MDAST) designed for application in East Africa. In developing MDAST, substantial gaps in the scientific evidence base were identified regarding insecticide resistance in malaria vector control and the effectiveness of alternative mosquito control approaches, including larviciding. We identify four entomological parameters in the model (two for insecticide resistance and two for larviciding) that involve high levels of uncertainty and to which outputs in MDAST are sensitive. We estimate and compare a VOI for combinations of these parameters in evaluating three policy alternatives relative to a status quo policy. We find having perfect information on the uncertain parameters could improve program net benefits by up to 5–21%, with the highest VOI associated with jointly eliminating uncertainty about reproductive speed of malaria‐transmitting mosquitoes and initial efficacy of larviciding at reducing the emergence of new adult mosquitoes. Future research on parameter uncertainty in decision analysis of malaria control policy should investigate the VOI with respect to other aspects of malaria transmission (such as antimalarial resistance), the costs of reducing uncertainty in these parameters, and the extent to which imperfect information about these parameters can improve payoffs. 相似文献

We investigate the relationship between exposure to Hurricanes Katrina and/or Rita and mental health resilience by vulnerability status, with particular focus on the mental health outcomes of single mothers versus the general public. We advance a measurable notion of mental health resilience to disaster events. We also calculate the economic costs of poor mental health days added by natural disaster exposure. Negative binomial analyses show that hurricane exposure increases the expected count of poor mental health days for all persons by 18.7% (95% confidence interval [CI], 7.44–31.14%), and by 71.88% (95% CI, 39.48–211.82%) for single females with children. Monthly time‐series show that single mothers have lower event resilience, experiencing higher added mental stress. Results also show that the count of poor mental health days is sensitive to hurricane intensity, increasing by a factor of 1.06 (95% CI, 1.02–1.10) for every billion (U.S.$) dollars of damage added for all exposed persons, and by a factor of 1.08 (95% CI, 1.03–1.14) for single mothers. We estimate that single mothers, as a group, suffered over $130 million in productivity loss from added postdisaster stress and disability. Results illustrate the measurability of mental health resilience as a two‐dimensional concept of resistance capacity and recovery time. Overall, we show that natural disasters regressively tax disadvantaged population strata. 相似文献

Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications
that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD.
This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults
(n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which
persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent
ADHD. 相似文献

The extent to which racial minority groups face discrimination in the labor market is the subject of considerable debate. Using William J. Wilson's thesis of the declining significance of race as our theoretical context, we provide further empirical evidence about labor market discrimination by investigating wages among African American, American Indian, Chinese American, Hispanic white, Japanese American, and non-Hispanic white men. We find, during the period before the civil rights movement, that a substantively significant wage disadvantage is evident for these minority groups with controls for observed labor force characteristics. In recent data, these net disadvantages are reduced substantially for each of these groups except Hispanics. With the exception of Hispanics, the results support Wilson's thesis. 相似文献
