We describe the origins, purposes, and findings of a national study to determine whether a large-scale program of blind proficiency testing in U.S. DNA laboratories is feasible and/or practical. Proficiency testing in clinical laboratories is reviewed, particularly as mandated by the Clinical Laboratory Improvement Acts and its role in the regulation of those laboratories. Proficiency testing in forensic urine drug testing labs is also briefly reviewed. Studies involving comparisons between open and blind proficiency testing are discussed. The clinical laboratory proficiency testing and regulation landscape provides the background for the DNA Act of 1994, and the congressional mandate to investigate blind proficiency testing in forensic DNA laboratories. Four models of blind proficiency testing are defined and discussed, along with the advantages and disadvantages of each and estimates of the costs of a large-scale program. The purposes of proficiency testing in a quality-assurance context are likewise discussed and related to the models and the arguments generally proffered for and against blind vs. open proficiency testing. 相似文献

Studies indicate that African American, Asian/Pacific Islander, and Latino youth have higher rates of unmet mental health
needs and lower rates of mental health service utilization compared to non-Hispanic White youth, suggesting that obstacles
may exist in the help-seeking and service utilization pathway for minority youth. Parental cultural factors may significantly
impact youth service use, and acculturation is one way to measure adherence to culture specific values, beliefs, attitudes,
and behaviors. In this study, parental acculturation level, conceptualized as cultural affinity to 1) mainstream American
culture and 2) an alternative culture, were examined as potential mediators of the relationship between race/ethnicity and
youth service use. The current subsample (n=1364) was drawn from the Patterns of Care study, a larger study of at-risk youth who were active to at least one of five
public sectors of care. Our subsample included all youth aged 6–17 who were African American, Asian/Pacific Islander, Latino,
or Non-Hispanic Whites (66.6% male). The results indicate that parental acculturation level as measured by affinity to an
Alternative Culture was a partial mediator in the relationship between race/ethnicity and mental health service use for Asian/Pacific
Islander and Latino youth.

Based on the premise that perception operates either as a catalyst or a constraint for a hegemonic war, this study examines ‘national perceptions’ (i.e. how the citizens of the two states view each other) and ‘official views’ (i.e. how the two governments perceive each other) between the US and China of the post-Cold War period. As for the national views, (1) American perceptions of China have generally become more negative than Chinese perceptions of America; (2) little congruence is found between the two powers on key values and norms; and (3) perceptions are generally getting far ahead of the realities. As for the official views, formal documents do not fully reveal their real state of minds. Diplomatic courtesy and strategic self-esteem runs through them. Yet, America’s strategic concern and growing will to manage China from a position of strength is increasingly more discernible. From the Chinese documents, on the other hand, signs of inferiority have gradually disappeared. In sum, perceptions between the two are working more as a catalyst for strategic competition than a constraint on it. 相似文献

Southeast Asian adolescents in the United States face the daily challenge of adjusting to the American culture and their culture of origin. However, little is known about how the patterns of their bicultural adjustment influence psychological symptoms, especially when faced with other challenges such as community violence and negative life events. Additionally, the overrepresentation of Southeast Asian youth in the mental health and juvenile justice systems also necessitates a deeper understanding of the adjustment of this group of adolescents. Data from a sample of 80 Vietnamese and Cambodian adolescents who were between 13 and 18 years old revealed high rates of community violence witnessing and victimization, and a moderate level of negative life events. All of these stressors were related to higher externalizing and trauma-related symptoms, but only violence victimization and negative life events were related to higher internalizing symptoms. There was an additive effect of higher bicultural orientation related to lower externalizing and traumatic-stress symptoms in the face of stress and violence exposure, but no moderation effects were found. 相似文献

This study examines correlates of in-law conflict with intimate partner violence (IPV) against pregnant women in a cohort of Chinese pregnant women who visited antenatal clinics in Hong Kong. This was a territory-wide, cross-sectional study of 3,245 pregnant women recruited from seven hospitals in Hong Kong. Participants were invited to complete the Chinese Abuse Assessment Screen and a demographic questionnaire. About 9% of the pregnant women reported having been abused by their partners in the preceding year. In-law conflict was the characteristic most significantly associated with preceding-year abuse against pregnant women, after controlling for covariates. Findings underscore the need to obtain information on in-law conflict as a risk factor for IPV. In-law conflict should be included in the assessment of risk for IPV. For the prevention of IPV, family-based intervention is needed to work with victims as well as in-laws. 相似文献

This article examines the decades‐long practices of performance budgeting in different countries and their associated challenges from a multilayered institutional framework. Based on theory and lessons learned, the article recommends an array of strategies to address institutional and organizational barriers. It also proposes to reconceptualize performance budgeting as a performance budget management system and suggests how multiyear budget planning, financial risk assessment, policy planning, the departmental budget cycle, the program budget cycle, stakeholder engagement, regular spending reviews, and performance audits should be integrated more closely to address the long‐term fiscal challenges faced by many governments and to respond to the public pressure on agencies to do more with less. 相似文献

The preservation of face is an important concept in Chinese behavioral patterns, both at individual and national levels. Beyond national interest considerations, modern-day diplomacy between China and the world also involves substantially the exchange of face. This article will argue that face represents a relational understanding of how China views and interacts with the world. By linking face to three themes that international relations scholars frequently use in describing how China sees the world, namely, the tribute system, the Chinese memory of historical humiliation and China’s distrust of the American-led international system, the article hopes to show how the understanding of face—as a crucial element of Chinese identity—can inform scholars and practitioners in their attempts to engage China. 相似文献
