The aim of this study was to analyze the influence of family context on the performance of 5‐year‐old children (N = 70) in theory of mind (ToM) tasks. The children's performances were assessed during individual sessions held at school. Children's verbal skills were assessed using the Peabody picture vocabulary test (PPVT). Interviews were also conducted with parents in the family home in order to gather sociodemographic data and to assess diverse variables of the family context. In addition to confirming the important role played by children's verbal skills in ToM, the results also supported a potential influence of family context in ToM development through variables, such as quality of non‐parental care or level of social contact and support. The educational implications of these results are discussed in relation to family intervention. 相似文献

ABSTRACT This study examines the influence of user motivations and behaviors on perceptions of mutually beneficial social resources accessible via connections formed and maintained on Facebook. Survey data collected from undergraduate Facebook users were used to construct a multiple-group structural equation model of male (n = 109) and female (n = 187) users to assess the effects of motivations, usage intensity, and general public self-disclosure on users’ perceptions of bridging and bonding social capital. Results indicate that status and relationship formation motivations directly affect both dimensions of social capital for all users. Formation motivation was found to positively affect public self-disclosure for male users, and usage intensity was found to mediate the positive effect of user motivations on public self-disclosure for both groups. General self-disclosure on public Facebook profiles was found to positively affect perceived bridging capital and mediated the effect of formation motivation on bridging capital only for male users, while public self-disclosure was not found to significantly predict either dimension of social capital among female users. Findings are discussed within the theoretical framework of social capital and the hyperpersonal model of computer-mediated communication, and directions for future research are proposed. 相似文献

Literature examining child support compliance among non-resident fathers has primarily come from the perspective of collecting
child support payments. Receiving limited attention in the literature has been the exclusive discussion of establishment of
paternity, which is related to child support compliance. Furthermore, the literature has given limited attention to never
married, cohabitating, unemployed, underemployed, and low-income, non-resident fathers. This study focuses on the intra- and
inter-networks these non-resident fathers utilize in fulfilling their child support obligations, establishing paternity. The
results indicate that non-resident fathers’ relationships with their former spouses or partners contribute to an increase
in the establishment of paternity. Implications for policymakers and program service delivery are offered. 相似文献

This paper provides closed form expressions for the sample size for two-level factorial experiments when the response is the number of defectives. The sample sizes are obtained by approximating the two-sided test for no effect through tests for the mean of a normal distribution, and borrowing the classical sample size solution for that problem. The proposals are appraised relative to the exact sample sizes computed numerically, without appealing to any approximation to the binomial distribution, and the use of the sample size tables provided is illustrated through an example. 相似文献

This study uses two waves of data to examine the relations among racial discrimination experiences, patterns of racial socialization practices, and psychological adjustment in a sample of 361 African American adolescents. Using latent class analyses, we identified four patterns of child‐reported racial socialization experiences: Moderate Positive, High Positive, Low Frequency, and Moderate Negative. Experiencing racial discrimination was associated with higher levels of depressive symptoms, more perceived stress, and lower levels of well‐being. On average, adolescents who experienced High Positive patterns of racial socialization reported the most positive psychological adjustment outcomes, while adolescents in the Low Frequency and Moderate Negative clusters reported the least favorable outcomes. Results suggest that High Positive racial socialization buffers the negative effects of racial discrimination on adolescents' perceived stress and problem behaviors. Together, the findings suggest that various patterns of racial socialization practices serve as risk, compensatory, and protective factors in African American adolescent psychological adjustment. 相似文献

Consider a random sample X1, X2,…, Xn, from a normal population with unknown mean and standard deviation. Only the sample size, mean and range are recorded and it is necessary to estimate the unknown population mean and standard deviation. In this paper the estimation of the mean and standard deviation is made from a Bayesian perspective by using a Markov Chain Monte Carlo (MCMC) algorithm to simulate samples from the intractable joint posterior distribution of the mean and standard deviation. The proposed methodology is applied to simulated and real data. The real data refers to the sugar content (oBRIX level) of orange juice produced in different countries. 相似文献

Asset Markets and Equilibrium Selection in Public Goods Games with Provision Points: An Experimental Study 总被引:1,自引:0,他引:1
We report experimental results on the effects that auctioning the right to play a public goods game with a provision point may have on equilibrium selection and individual behavior. Auctioning off such a right among a larger population of players strikingly enhances public good provision. Once public good provision is obtained, the auction price at the preliminary stage increases to its upper limit, dissipating all players' gains associated with the provision of the public good. Individual deviations from the equilibrium strategy are neither able to force lower market prices nor to affect provision of the public good in subsequent periods. (JEL C72 , C92 , H41 ) 相似文献

ABSTRACT Our current age of connectedness has facilitated a boom in interactive dynamics within social networking sites. It is, therefore, possible for the field of Social Work to draw on these advantages in order to connect with the unconnected by strengthening online mutual support networks among users. The aim of this article is to examine whether ‘connectedness’ in social networking sites improves online social capital and resilience of social service users. Through our analysis of social networks carried out on an experimental model, we observed the patterns of connectedness on Facebook of 50 social service end-users from Málaga, Spain. The detection of online communities through the modularity algorithm has allowed us to ascertain whether individuals’ offline realities mirror their online realities. At the same time, we examined the influence certain interactions (likes, comments, etc.) have on leadership through online ethnography. Finally, online social capital, understood as the combination of connectedness and online interaction, has been correlated with users’ resilience. The results reveal that both connectedness and interaction feed themselves and have correlations with resilience. 相似文献
