Recent research has revealed the important role of multimodal object exploration in infants' cognitive and social development. Yet, the real‐time effects of postural position on infants' object exploration have been largely ignored. In the current study, 5‐ to 7‐month‐old infants (N = 29) handled objects while placed in supported sitting, supine, and prone postures, and their spontaneous exploratory behaviors were observed. Infants produced more manual, oral, and visual exploration in sitting compared to lying supine and prone. Moreover, while sitting, infants more often coupled manual exploration with mouthing and visual examination. Infants' opportunities for learning from object exploration are embedded within a real‐time postural context that constrains the quantity and quality of exploratory behavior. 相似文献

Previous studies find that some social groups are stuck in poverty traps because of network effects. However, these studies do not carefully analyze how these groups overcome low human capital investment activities. Unlike previous studies, the model in this paper includes network externalities in both the human capital investment stage and the subsequent career stages. This implies that not only the current network quality, but also the expectations about future network quality affect the current investment decision. Consequently, the coordinated expectation among the group members can play a crucial role in the determination of the final state. We define “overlap” for some initial skill ranges, whereby the economic performance of a group can be improved simply by increasing expectations of a brighter future. We also define “poverty trap” for some ranges, wherein a disadvantaged group is constrained by its history, and we explore the egalitarian policies to mobilize the group out of the trap. 相似文献

This study utilized the community structure approach to analyze newspaper coverage of posttraumatic stress (PTS) in veterans in 26 U.S. cities. The study examined whether media placed responsibility for PTS treatment on government or society through a review of 353 articles from March 20, 2003, to March 20, 2013. Researchers coded articles for “prominence” and “direction” to produce a “Media Vector” for each paper, ranging from 0.8403 to ?0.3592. Results showed that 25 of 26 Media Vectors (96%) supported government responsibility. Pearson correlations yielded nine significant findings. Results disconfirmed buffer hypotheses linking privilege with support for government responsibility (privilege defined by percentage of college educated, percentage of family income $100,000 or more, and percentage of professional/technical occupational status; r = ?.486, ?.524, ?.553, respectively, significant at the .006 level). Stakeholder hypotheses were also disconfirmed; greater percentages of age 65 and older correlated with more emphasis on government responsibility (r = .340, p = .048), whereas greater percentages of age 25 to 44 correlated with less emphasis (r = ?.342, p = .047). The only confirmed hypothesis linked percentage of age 45 to 64 with less emphasis on government responsibility (r = ?.559, p = .002). A regional finding was noteworthy: Media in the Midwest supported government responsibility more than other regions. Regression analysis revealed three variables influencing coverage most significantly: Family Income $100K+ (26% of variance), Percentage of Hispanic (8%), and Professional/Technical Occupational status (5%). It must be noted that nearly all newspapers yielded positive Media Vectors. This indicates that coverage in major cities generally favors government responsibility for veterans' PTS treatment, and Pearson correlation results may represent differences in the degree of support and demographic characteristics influencing this support. 相似文献

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision. 相似文献

Maternal education differences in children's academic skills have been strongly linked to parental investment behaviors. This study extended this line of research to investigate whether these same maternal education patterns in parenting are observed among a set of parenting behaviors that are linked to young children's health. Drawing on data from the Early Childhood Longitudinal Study, Birth Cohort (n = 5,000) and longitudinal models incorporating random effects, the authors found that higher levels of maternal education were associated with more advantageous health investment behaviors at each phase of early development (9 months, 2 years, 4 years, 5 years). Moreover, these disparities were typically largest at the developmental stage when it was potentially most sensitive for children's long‐term health and development. These findings provide further evidence of a developmental gradient associated with mothers' education and new insight into the salience of mothers' education for the short‐ and long‐term health and well‐being of their children. 相似文献

Using data from the 2006 Family Module of the East Asian Social Survey (N = 3,096), this article examines associations of marital satisfaction with divisions of housework and gender ideology in four East Asian societies: urban China, Japan, South Korea, and Taiwan. Compared with Japanese and Korean married women and men, Chinese and Taiwanese spouses were more satisfied with their marriage and had more egalitarian divisions of housework, but simultaneously they held less egalitarian gender ideologies. Multivariate analyses showed that relative share of housework was negatively associated with marital satisfaction for Japanese and Korean men and for Korean and Taiwanese women. Egalitarian gender ideology was significantly associated with lower marital satisfaction only among Taiwanese women. In addition, the negative association between housework and marital satisfaction was more pronounced for Taiwanese women who espoused more egalitarian gender ideologies. The authors discuss how differences in macro‐level social contexts explain these cross‐society variations. 相似文献

The authors examined the hypothesis that many individuals define monogamy based on emotional rather than sexual fidelity. Participants, 373 heterosexual college students and 282 gay men, read three vignettes of decreasing mitigation in which they imagined committing an act of infidelity against a hypothetical partner and where half the participants were cued to their emotional attachment toward the partner. Despite the infidelity, relationships in the emotional attachment–cued vignettes were rated as monogamous to a greater degree than relationships in the vignettes where emotional attachment was not cued. In addition, over one-third of the participants in our study reported infidelity in their current self-defined monogamous relationships yet also reported feeling more protected from sexual health risks and reported less condom use than individuals who defined their relationship as nonmonogamous. The implications for monogamy as a protective fallacy are discussed. 相似文献

In the early seventeenth century, important socioeconomic changes in the Spanish colony of Hispaniola brought about substantial shifts in race relations between white residents and peoples of African descent, who were enslaved and free. As the plantation system declined precipitously, white members of the Spanish elite started envisioning new roles for enslaved laborers, which included enrolling these enslaved peoples in their own intrigues against other elites. This cooperation led people in bondage to carry out violent attacks and assassination plots against other members of the white colonial society. People of African descent took advantage of these collaborations as an opportunity to advance their own interests within the community. Nevertheless, people of African descent faced fierce and often violent backlash if they acted of their own accord. 相似文献

In therapeutic conversations, questions can be considered as interventions in their own right. This study is a cross‐cultural replication of Grant (Journal of Systemic Therapies, 2012, 31, 2, 21) study on the effects of different types of questions on various clinically relevant variables. A total of 204 students of a Spanish university described a real‐life problem that they wanted to solve and were then randomly assigned to either a solution‐focused or a problem‐focused questions condition. Before and after answering the questions, they completed a set of measures that assessed positive and negative affect, self‐efficacy, and goal attainment. Solution‐focused questions produced a significantly greater increase in self‐efficacy, goal approach, and action steps than problem‐focused questions, and a significantly greater decrease in negative affect, providing further empirical support to solution‐focused practices. 相似文献
