Some commentators claim that white Americans put prejudice behind them when evaluating presidential candidates in 2008. Previous
research examining whether white racism hurts black candidates has yielded mixed results. Fortunately, the presidential candidacy
of Barack Obama provides an opportunity to examine more rigorously whether prejudice disadvantages black candidates. I also
make use of an innovation in the measurement of racial stereotypes in the 2008 American National Election Studies survey,
which yields higher levels of reporting of racial stereotypes among white respondents. I find that negative stereotypes about
blacks significantly eroded white support for Barack Obama. Further, racial stereotypes do not predict support for previous
Democratic presidential candidates or current prominent Democrats, indicating that white voters punished Obama for his race
rather than his party affiliation. Finally, prejudice had a particularly large impact on the voting decisions of Independents
and a substantial impact on Democrats but very little influence on Republicans. 相似文献

Rejection sensitivity (RS) refers to the tendency to anxiously expect, readily perceive, and overreact to experiences of possible rejection. RS is a clear risk factor for psychological maladaptation during early adolescence. However, there is growing evidence of significant heterogeneity in the psychological correlates of RS. To investigate when RS poses the greatest psychological risk during early adolescence, this study examines mutual best friendship involvement (or lack thereof) and the best friends?? RS as potential moderators of the associations between RS and psychological difficulties. Participants were 150 7th grade students (58 boys; M age = 13.05 years) who nominated their best friends, and reported on their RS, social anxiety, and self-esteem. Results from a series of hierarchical multiple regression analyses indicated that mutual best friendship involvement and best friends?? RS were both significant moderators when fear of negative evaluation (a type of social anxiety) served as the dependent variable. The association between RS and fear of negative evaluation was stronger for adolescents without mutual best friends than adolescents with mutual best friends. In addition, the association between RS and fear of negative evaluation was the strongest for adolescents whose best friends were highly rejection sensitive (relative to adolescents whose best friends were moderately or low in RS). Findings highlight the importance of considering best friendships in studies of RS and strongly suggest that, although having mutual best friendships may be protective for rejection sensitive adolescents, having a rejection sensitive best friend may exacerbate difficulties. The significance of friends in the lives of rejection sensitive adolescents is discussed as well as possible applied implications of the findings and study limitations. 相似文献

Abstract: DNA mixtures with two or more contributors are a prevalent form of biological evidence. Mixture interpretation is complicated by the possibility of different genotype combinations that can explain the short tandem repeat (STR) data. Current human review simplifies this interpretation by applying thresholds to qualitatively treat STR data peaks as all‐or‐none events and assigning allele pairs equal likelihood. Computer review, however, can work instead with all the quantitative data to preserve more identification information. The present study examined the extent to which quantitative computer interpretation could elicit more identification information than human review from the same adjudicated two‐person mixture data. The base 10 logarithm of a DNA match statistic is a standard information measure that permits such a comparison. On eight mixtures having two unknown contributors, we found that quantitative computer interpretation gave an average information increase of 6.24 log units (min = 2.32, max = 10.49) over qualitative human review. On eight other mixtures with a known victim reference and one unknown contributor, quantitative interpretation averaged a 4.67 log factor increase (min = 1.00, max = 11.31) over qualitative review. This study provides a general treatment of DNA interpretation methods (including mixtures) that encompasses both quantitative and qualitative review. Validation methods are introduced that can assess the efficacy and reproducibility of any DNA interpretation method. An in‐depth case example highlights 10 reasons (at 10 different loci) why quantitative probability modeling preserves more identification information than qualitative threshold methods. The results validate TrueAllele® DNA mixture interpretation and establish a significant information improvement over human review. 相似文献

Abstract The literature on intelligence little describes or comparatively analyzes the intelligence services of insurgent groups. This article partially fills the gap by assessing the intelligence activities of FARC – the Revolutionary Armed Forces of Colombia. FARC intelligence displays similarities to, as well as sharp differences from, the intelligence activities of other insurgent groups and established states. Like FARC as a whole, FARC intelligence is decentralized. Its strength is its focus on tactical military intelligence. Collection on strategic political issues, analysis, and counterintelligence are relatively weak. FARC's intelligence weaknesses limit its prospects for strategic success and its intelligence-related vulnerabilities offer the Colombian government opportunities to exploit. 相似文献

People with severe mental illness evidence significantly higher rates of HIV infection than the general population in the United States. Frequently, the only access to health care for this population is through their outpatient mental health care providers. In order to determine how these providers were dealing with the increased risk of HIV infection among this group, a survey of all licensed and certified outpatient mental health care centers in New York State was conducted. The data were compared to a similar previous survey conducted in 1997. 相似文献

Research on domestic violence against women has increased considerably over the past few decades. Most participants in such studies find the exercise worthwhile and of greater benefit than emotional cost; however, systematic examination of participant reaction to research on violence is considerably lacking, especially in the Middle East region. This study begins to fill this gap by examining women's reactions to domestic violence research in Jordan and whether a personal history of violence is associated with unfavorable experiences. This sequential exploratory mixed methods study included 17 focus group discussions (FGD) with women in Amman followed by a survey conducted in reproductive health clinics throughout the country (pilot n = 30; survey n = 517). Open coding was used to identify the theme related to participant reaction in the FGD data. This construct was further examined by the subsequent survey that included dichotomous questions inquiring whether the respondent thought the study questions were important and whether they were angry or felt resentment as a result of the survey. One open-ended question on the survey provided additional qualitative data on the theme that was combined with the FGD data. Themes identified in the qualitative data pertained to expressions of gratitude and comments on the survey's value. Findings of this study indicate that Jordanian women's responses to the research process are similar to women currently represented by the extant literature in that a vast majority of its participants felt that the study was important (95%) and it did not evoke anger or resentment (96%). Many even found the study to be useful to them personally or to society. Among those who had a negative emotional reaction, most still found the research to be important. This study's findings highlight the safety and potential benefits of ethically conducted violence research. 相似文献
