The subject of this article is the changing balance between Russia's positive and negative interests in the Conference on/Organisation for Security and Cooperation in Europe (CSCE/OSCE) as these have evolved in relation to Western policies on the OSCE and European security relations in general. Parallel to the decline of positive Russian interests in the CSCE/OSCE, an increase in negative attitudes can be observed, most of which concern the OSCE's activities in post-Soviet countries. While the Soviet Union was traditionally a reliable supporter of the CSCE, the Russian Federation, which initially pursued the same policy, has lost most of its sense of ownership in the OSCE. This change in Russian attitudes is critical for the Organisation's future, for an OSCE without active Russian participation would lose much of its raison d'être. 相似文献

Presidents traditionally have had great success when nominating justices to the Supreme Court, with confirmation being the norm and rejection being the rare exception. While the confirmation process usually ends with the nominee taking a seat on the Court, however, there is a great deal of variance in the amount of time it takes the Senate to act. To derive a theoretical explanation of this underlying dynamic in the confirmation process, we draw on a spatial model of presidential nominations to the Court. We then employ a hazard model to test this explanation, using data on all Supreme Court nominations and confirmations since the end of the Civil War. Our primary finding is that the duration of the confirmation process increases as the ideological distance between the president and the Senate increases. We also find evidence that suggests that the duration increases for critical nominees and chief justices and decreases for older nominees, current and previous senators, and nominees with prior experience on state and federal district courts . 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

Some Aboriginal youth are at disproportionate risk of using substances and developing abuse and dependence disorders. However,
not all Aboriginal youth misuse substances and limited research has examined the protective factors conferring against substance
use among these youth. The present study aimed to identify protective factors related to the alcohol use trajectories from
early adolescence to emerging adulthood among off-reserve Canadian Aboriginal youth. Participants (N = 330; 50.3% male) aged 12–23 were selected from cycles 2–7 of Statistics Canada’s NLSCY. Multilevel modeling was employed
to identify protective factors for two constructs of alcohol use. Participation in weekly activities and optimism were found
to be protective for both the frequency of alcohol use and heavy drinking trajectories. Attendance of religious services was
also found to be protective for heavy drinking behaviors. In contrast, positive peer relationships were a risk factor for
frequency of alcohol use, but not heavy drinking. The results provide preliminary evidence of important developmental factors
to integrate into substance use intervention programs targeting Aboriginal youth. 相似文献

Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to
academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family
(i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally
positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism,
gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years
and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to
junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family
role models assessed when adolescents were in 5th grade positively related to academic performance in 7th grade. Further,
being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related
to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade
academic performance. Implications for future research and interventions are discussed. 相似文献

Experiences with perceived discrimination (e.g., perceptions of being treated unfairly due to race or ethnicity) are expected to impact negatively youths’ prosocial development. However, resilience often occurs in light of such experiences through cultural factors. The current longitudinal study examined the influence of perceived discrimination on the emergence of Mexican American adolescents’ later prosocial tendencies, and examined the mediating role of Mexican American values (e.g., familism, respect, and religiosity). Participants included 749 adolescents (49 % female) interviewed at 5th, 7th, and 10th grade. Results of the current study suggested that, although perceived discrimination was associated negatively with some types of prosocial tendencies (e.g., compliant, emotional, and dire) and related positively to public prosocial helping, the associations were mediated by youths’ Mexican American values. Directions for future research are presented and practical implications for promoting adolescents’ resilience are discussed. 相似文献
