The quality of family relationships and youth friendships are intricately linked. Previous studies have examined different mechanisms of family-peer linkage, but few have examined social anxiety. The present study examined whether parental rejection and family climate predicted changes in youth social anxiety, which in turn predicted changes in friendship quality and loneliness. Possible bidirectional associations also were examined. Data for mothers, fathers, and youth (M age at Time 1?=?11.27; 52.3% were female) from 687 two-parent households over three time points are presented. Results from autoregressive, cross-lagged analyses revealed that father rejection (not mother rejection or family climate) at Time 1 (Fall of 6th Grade) predicted increased youth social anxiety at Time 2 (Spring of 7th Grade), which in turn, predicted increased loneliness at Time 3 (Spring of 8th Grade). The indirect effect of father rejection on loneliness was statistically significant. Mother rejection, father rejection, and a poor family climate were associated with decreased friendship quality and increased loneliness over time. Finally, there was some evidence of transactional associations between father rejection and youth social anxiety as well as between social anxiety and loneliness. This study’s findings underscore the important role of fathers in youth social anxiety and subsequent social adjustment.  相似文献

Are state governments fulfilling their responsibilities to be model employers of women and minorities? Using U.S. Census Bureau data on individual employees from 1980 to 2015, this article looks at how much progress state governments have made toward eliminating racial and gender pay differences. It examines whether differences in education, age/experience, citizenship, English ability, hours worked, and occupation explain the pay differences. Patterns and explanations vary substantially by group, but state governments are doing a better job than private firms of closing pay gaps on almost every measure .  相似文献

Recent studies show a clear link between women in government and reduced concerns about corruption. Until now, it remains unclear which underlying attitudes about women explain the perception that they will reduce corruption. Using a survey question about adding women to a police force, with an embedded experimental treatment, we examine three distinct stereotypes that might explain the power of women to reduce concerns about corruption: gender stereotypes of women as more ethical and honest, the perception of women as political outsiders, and beliefs that women are generally more risk averse. We find that people do perceive women as more effective at combating corruption, and these perceptions are greatly enhanced when information about women's outsider status and risk aversion is provided.  相似文献

This article examines the lack of policy response to the 1990 U.S. National Intelligence Estimate (NIE) that predicted the collapse of Yugoslavia. Contrary to common criticisms of estimative intelligence, the NIE was accurate and unambiguous. Why was good intelligence unheeded? For some policymakers, the analysis was not closely tied to their interests and competed with other priorities for attention; for those who were substantive experts, the NIE’s grim message was hard to accept. Moreover, policymakers read intelligence reports in the context of popular concepts – a lingering Cold War lens distorted more than it clarified. Finally, while the NIE made hard-hitting judgments, it did not include any analysis of opportunities to influence the outcome. Rather than pushing an already difficult estimate to the breaking point, including opportunities would likely have increased the odds of policymakers taking action. These lessons have broader implications for analytical tradecraft and the often-challenging relationship between intelligence and policy.  相似文献

Swidden has historically been one of the most widespread land uses in upland Southeast Asia. In recent decades, swidden systems across the region have undergone rapid transformation. While most analyses focus on swidden as a livelihood practice, we direct attention to the political nature of swidden. Drawing on qualitative fieldwork and household surveys from two villages in East Kalimantan Province, Indonesia, we examine the politics of swidden along two key dimensions. First, at the household level, we describe swidden as a land control strategy. We identify territorialization and speculation as drivers of ‘contentious land change’ in swidden systems under pressure from expanding plantations and mines. Second, at the village and district levels, we examine the politics of swidden within new forest governance arrangements. Control of swidden has provided a focus for multi-stakeholder forest governance, but with ambivalent effects, developing village land management and livelihoods at a cost of temporary increases in swidden clearing and with minimal impact on deforestation for industrial land uses. Our analysis suggests forest governance efforts will be ineffective in eliminating contentious land change or reducing district-level deforestation until they address plantation and mining expansion as the dominant direct and indirect drivers of forest conversion.  相似文献

The emergence of innovative family and child protection dispute resolution (DR) methods has resulted in a varying array of communication protections. Review of these communication protections in the United States reveals a lack of consistency and clarity within each form of DR, and no clear policy to guide the development of the different communication protections across the spectrum of DR methods. This article proposes a new term, privadentiality, to describe communication protections which may be provided for a wide range of DR methods and a framework for categorizing DR methods in order to develop more consistent and appropriate communication protections across the spectrum of DR. This article concludes with recommendations to improve party and professional understanding of DR communication protections; protect families from escalating conflict; promote the integrity of DR methods; and enable courts to appropriately review and, where appropriate, approve DR outcomes.  相似文献

This article describes trends in suicide attempt visits to emergency departments in the United States (US). Data were obtained from the National Hospital Ambulatory Medical Care Survey using mental-health-related ICD-9-CM, E and V codes, and mental-health reasons for visit. From 1992 to 2001, mental-health-related visits increased 27.5% from 17.1 to 23.6 per 1000 (p < .001). Emergency Department (ED) visits for suicide attempt and self injury increased by 47%, from 0.8 to 1.5 visits per 1000 US population (p(trend) = .04). Suicide-attempt-related visits increased significantly among males over the decade and among females from 1992/1993 to 1998/1999. Suicide attempt visits increased in non-Hispanic whites, patients under 15 years or those between 50-69 years of age, and the privately insured. Hospitalization rates for suicide attempt-related ED visits declined from 49% to 32% between 1992 and 2001 (p = .04). Suicide attempt-related visits increased significantly in urban areas, but in rural areas suicide attempt visits stayed relatively constant, despite significant rural decreases in mental-health related visits overall. Ten-year regional increases in suicide attempt-related visits were significant for the West and Northeast only. US emergency departments have witnessed increasing rates of ED visits for suicide attempts during a decade of significant reciprocal decreases in postattempt hospitalization. Emergency departments are increasingly important sites for identifying, assessing and treating individuals with suicidal behavior.  相似文献

Cigarette smoking is concentrated among low‐income groups. Consequently, cigarette taxes are considered regressive. However, if poorer individuals are much more price sensitive than richer individuals, then tax increases would reduce smoking much more among the poor and their cigarette tax expenditures as a share of income would rise by much less than for the rich. Warner (2000) said this phenomenon would make cigarette tax increases progressive. We test this empirically. Among low‐, middle‐, and high‐income groups, we estimate total price elasticities of _0.37, _0.35, and _0.20, respectively. We find that cigarette tax increases are not close to progressive, using both tax expenditure‐based and traditional welfare measures. This finding is robust to cross‐border purchasing, generic cigarettes, and substantial external effects. However, we find that taxes can be progressive under some behavioral economic models (Gruber & Koszegi, 2004) but that these may only apply to a small share of smokers. © 2008 by the Association for Public Policy Analysis and Management.  相似文献

While Sino-Japanese relations are quite stable presently, it was as recent as 2004–2005 that the two nations slid into the worst bilateral quagmire in decades. When in 2007 Japan was China’s third largest trading partner and China surpassed the US to become Japan’s largest trading partner, what is eating these two otherwise very pragmatic traders? History, nationalism and face, enabled by recent changes in the strategic environment, are the factors that have been most salient in bringing about the plunge in Sino-Japanese relations in 2004–05 and though Sino-Japanese relations have been much better since, these factors hang like a storm front over Sino-Japanese relations today.  相似文献
