In 2007 Ellison, Steinfield, and Lampe published an article on the positive association between Facebook use and social capital that started a decade of research on the social outcomes of social network site use. Although cited almost 9,000 times, it received critique on the conceptualization and operationalization of Facebook use and social capital. In this study we replicate Ellison et al.’s study with original and alternative measures of social capital and Facebook use, thereby shedding light on the robustness, stability, and ecological validity of the original findings. We found that Facebook intensity positively predicts the original social capital measures, lending support to the validity of the original findings. Its relationship with structural measures, however, was weak for bridging and absent for bonding social capital. 相似文献

Nationwide, school districts struggle to recruit and retain Black males to the teaching profession. As a result, the presence of Black male teachers is lacking in public schools, which impacts the overall student outcomes for all children, particularly Black boys. Such recruitment and retention becomes even worse at the early childhood level, which explains the paucity of Black male teachers who are early childhood educators. To date, only 2% of teachers are Black males, of which most are middle and high school teachers. Furthermore, the clarion call for Black males to become teachers does not often prioritize Black male teachers who are culturally relevant. In this article, we focus on educational research regarding the lack of diversity of teachers and among males in K-12 to provide recommendations to the field of early childhood education, with specific attention to recruiting and retaining culturally relevant Black male teachers in early childhood education. 相似文献

World class pioneering achievements are a nation's most valuable asset. They arise from the efforts of talents‐people of extraordinary ability. The vital task of fostering the emergence of such talents requires a concentrated effort covering the entire lifespan. Significant factors are parents, contemporaries and teachers as well as media, the societal atmosphere and contact with great social and scientific issues. These must act together to produce talents with not only the ability but also the dedication to achieve.

Improved understanding of mobility performance in wheelchair basketball is required to increase game performance. The aim of this study was to quantify the wheelchair-athlete activities of players in different field positions and of different playing standard during wheelchair basketball matches. From video analysis, absolute and relative duration and frequency of wheelchair movements and athlete control options were examined in 27 national standard and 29 international standard players during entire wheelchair basketball matches. Between-group factorial analysis of variances identified that national players drove more forward (42.6 ± 6.8 vs. 35.4 ± 3.7%; effect size Cohen’s d (ES) = 1.48) and started more often driving forward (33.9 ± 2.6 vs. 31.8 ± 2.8; ES = 0.77) during a match while the mean activity duration for a single driving forward activity was longer (4.3 ± 0.9 vs. 3.7 ± 0.6 s; ES = 0.75) than for international players. Furthermore, national players performed fewer rotational movements (21.8 ± 4.0 vs. 28.9 ± 7.8%; ES = –1.30) and started less often with the rotational movements (35.0 ± 3.6 vs. 40.5 ± 5.5; ES = –1.21) while the mean activity duration for a single rotation activity was shorter (2.1 ± 0.3 vs. 2.3 ± 0.3 s; ES = –0.67) than for international players. Differences in mobility performance among guard, forward and centre players were minimal. The results should help wheelchair basketball coaches specify wheelchair-handling training techniques and means to optimise wheelchair-athlete configurations. 相似文献

The physiology of vascular endothelial cells is strongly affected by fluid shear stress on their surface. In this study, a microfluidic assay was employed to analyze the alignment of actin filaments in endothelial cells in response to shear stress. When cells were cultured in microfluidic channels and subjected to shear stress, the alignment of filaments in the channel direction was significantly higher than in static cultures. By adding inhibitory drugs, the roles of several signaling proteins in the process of alignment were determined. Thus, it is shown how microfluidic technology can be employed to provide a mechanistic insight into cell physiology. 相似文献

OBJECTIVE: To determine whether infants have a traumatic response to intimate partner violence (male violence toward their female partner; IPV) experienced by their mothers, two questions were explored: (1) Is the number of infant trauma symptoms related to the infant's temperament and the mother's mental health? (2) Does severity of violence moderate those relationships? METHODOLOGY: Forty-eight mothers reported whether their 1-year-old infants experienced trauma symptoms as a result of witnessing episodes of IPV during their first year of life. Mothers also reported on their own trauma symptoms that resulted from experiences of IPV. RESULTS: For those infants experiencing severe IPV and whose mothers exhibit trauma symptoms, we were able to predict whether infants exhibited trauma symptoms (b = .53, p < .01). This was not true for children who witnessed less severe IPV (b= -.14, ns). Maternal depressive symptoms and difficult infant temperament did not predict infant trauma symptoms for either group of infants. CONCLUSION: Mothers report that infants as young as 1-year-old can experience trauma symptoms as a result of hearing or witnessing IPV. The significant relationship between infant and maternal trauma symptoms, especially among those infants experiencing severe IPV, are consistent with the theory of relational PTSD. Findings suggest that interventions for mothers and families need to consider the influence of the severity of IPV on very young children. 相似文献
