Growth in economic disparities, economic segregation, and racial/ethnic diversity have occurred in tandem in the U.S., leading to essential questions concerning whether the benefits of economic resources are shared across diverse groups. Analyzing a sample of eighth grade early adolescents (age 14 years) drawn from the nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (N?=?7625; 59% White, 12% Black, 19% Hispanic, 7% Asian, 2% Native American, and 2% multiracial; 47% female), lagged regression models assessed links between family, neighborhood, and school income and adolescent emotional and behavioral functioning. The results found that family income was associated with heightened emotional and behavioral functioning, and school income with improved behavioral functioning for White adolescents, whereas no benefits emerged for Black or Hispanic youth. In contrast, mixed associations emerged between income and early adolescent functioning for Asian and American Indian youth, with predominantly negative links appearing for multiracial youth. These patterns highlight diversity in the potential benefits and costs of economic resources, and suggest the need to better specify mechanisms through which economic disparities affect youth from varied backgrounds. 相似文献

The understanding of positive development across adolescence rests on having a valid and equivalent measure of this construct across the breadth of this period of life. Does the Positive Youth Development (PYD) construct based on the Five Cs model have satisfactory psychometric properties for such longitudinal measurement invariance? Using longitudinal data derived from the 4-H Study of PYD, we assessed 920 youth (61.6% female) from a racially and ethically diverse sample (67.3% European American) who participated in three waves (Grades 8–10) of data collection. Building on prior findings that the Five Cs (i.e., Competence, Confidence, Connection, Character, and Caring) model of PYD was a robust measure that could be assessed comparably during early adolescence, we tested a hierarchy of second-order confirmatory factor analysis models to assess the extent to which PYD can be measured equivalently across middle adolescence. Evidence was found for strict measurement invariance across three measurement occasions, including equivalence of first-order and second-order factor loadings, equality of intercepts of observed variables, and equality of item uniqueness and disturbances of the first-order factors. These results suggest that PYD can be measured in the same way across measurement occasions, a prerequisite for the study of development. Implications for research and application of being able to measure PYD equivalently across adolescence are discussed. 相似文献

Sociometric nominations, social cognitive maps, and self-report questionnaires were completed in consecutive years by 327
students (56% girls) followed longitudinally from grade 7 to grade 8 to examine the stability of social standing in peer groups
and correlates of changes in social standing. Social preference, perceived popularity, network centrality, and leadership
were moderately stable from grade 7 to grade 8. Alcohol use and relational aggression in grade 7 predicted changes in social
preference and centrality, respectively, between grade 7 and grade 8, but these effects were moderated by gender and ethnicity.
Changes in social standing from grade 7 to grade 8 were unrelated to grade 8 physical aggression, relational aggression, and
alcohol use after controlling for the grade 7 corollaries of these behaviors. Results are discussed in terms of their implications
for understanding links between social standing and problem behaviors during adolescence.

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors. 相似文献

This article uses a new dataset of coded Alberta Throne Speeches from 1906 to 2017 to identify patterns of provincial policy attention to place and urban place across policy issues and time. We discuss three main findings. First, provincial attention to place and urban place is influenced by policy domain: place‐based attention is generally absent in some policy domains, such as macroeconomic policy, and prevalent in others, such as health care. Second, place‐based attention is patterned over time, with a noticeable peak in the post‐war “province‐building” years and distinct troughs in other periods. Finally, we discuss the related but distinct patterns of attention to place and urban place across policy domains and time. 相似文献

Discourse on terrorist violence has long facilitated an especially liberal form of securitisation. Originally evoked in reference to anarchists and communists, a rational consideration of terrorist violence, inaugurated by the concept, asks for deferred judgement about the nature of, or reasons behind, violence related to terror on the premise that state and international legal norms governing the legitimate use of violence fail to circumscribe the proper capacities of the state to regulate and explain terrorism. Where sovereign powers along with their military and civilian instruments of coercion are deemed unable to regulate violence effectively, analysts of terrorist violence and their readership are invited to consider and cultivate new sensibilities. Beginning in the 1980s, studies by psychologists found renewed urgency among a growing cadre of interdisciplinary terror experts who found religion, Islam especially, a key variable of analysis. I situate their contributions in a longer history of secular and racialising discourse about terrorist violence. Central to this history are practices of reading, translating, interpreting and archiving texts. Evidence for the argument is based on the analysis of an algorithm that allegedly predicts the likelihood of terrorist strikes by counting words spoken by al-Qa?ida leaders and correlating their frequency with over 30 psychological categories. 相似文献

International criminal courts are often given mandates without the authority or resources to enforce those directives. Given this, how do they achieve their objectives? We argue that in the case of the International Criminal Tribunal for the former Yugoslavia (ICTY), the court strategically developed an accountability network comprised of governmental and nongovernmental actors, using its expertise and position to provide information and a framework of accountability. Simultaneously, it reached out to a range of actors to ensure that governments and international organizations would push Balkan states to cooperate with the ICTY, thereby amplifying the court's power. Utilizing correspondence data, we create a unique dataset that traces the development of this accountability network, demonstrating how this institution engaged networks to pursue its goals. In general, we demonstrate that, although institutions may lack compulsory power, they can engage in strategic behavior using networks to project their productive power. 相似文献

The mismatch between the housing needs of persons with a disability and the housing programs designed to accommodate those needs is an important housing policy concern. The U.S. Department of Housing and Urban Development (HUD) sponsors several programs designed to improve the housing conditions of persons with a disability, but we know little about the characteristics of persons with a disability, among those receiving federal housing assistance, or the degree to which persons with a disability are served by HUD-sponsored housing programs that are designed to meet the needs of persons with a disability. Our study relies on administrative data from HUD and the U.S. Census Bureau to address this research gap. We find that many persons with a disability are served by HUD-sponsored programs that are not designated for persons with a disability, even when disability accommodations have been requested, and a similarly large share of persons with a disability live in potentially eligible low-income households that do not receive HUD assistance. 相似文献

A Concurrent Analysis of Three Institutions that Transform Health Technology‐Based Ventures: Economic Policy,Capital Investment,and Market Approval 下载免费PDF全文
Drawing on institutional theory, this article articulates qualitative insights from a program of research on Canadian health technology‐based ventures to examine the rules that characterize economic policy, capital investment, and regulatory approval as well as the way these institutions enable and constrain the development of ventures at an early stage. Our findings clarify how economic policy integrates these ventures into the entrepreneurial domain, how capital investment configures them for economic value extraction, and how regulatory approval fully releases their market value. These findings help to revisit current policy modernization initiatives by calling attention to the convergence among the three institutions. Rather than operating solely as a source of constraints, these institutions provide a highly integrated market‐oriented space for health technology‐based entrepreneurial activities to unfold. 相似文献
