With governments around the world needing to attract talented professionals, this exploratory, cross-cultural research analyzes career values of 384 MPA and MPP students at major universities in the capitals of China, Malaysia and the United States. Malaysians and Americans structured 23 goals along dimensions that contrasted sharply to those of the Chinese. Moreover, Malaysians and Americans cared more about self-actualization and less about co-worker comradeship than did the Chinese. All three groups prioritized elements of altruism and affluence. Segmentation analysis uncovered six distinct subgroups (Acheivers, Altruistic Analysts, Administrators, Altruistic Affluents, Acquiescents, and Apathetics) with their distributions varying by country. 相似文献

Enhanced images may improve bite mark edge definition, assisting forensic analysis. Current contrast enhancement involves color extraction, viewing layered images by channel. A novel technique, producing a single enhanced image using the grayscale mix panel within Adobe Camera Raw®, has been developed and assessed here, allowing adjustments of multiple color channels simultaneously. Stage 1 measured RGB values in 72 versions of a color chart image; eight sliders in Photoshop® were adjusted at 25% intervals, all corresponding colors affected. Stage 2 used a bite mark image, and found only red, orange, and yellow sliders had discernable effects. Stage 3 assessed modality preference between color, grayscale, and enhanced images; on average, the 22 survey participants chose the enhanced image as better defined for nine out of 10 bite marks. The study has shown potential benefits for this new technique. However, further research is needed before use in the analysis of bite marks. 相似文献

The Supreme Court of Canada recently issued a trilogy of decisions pertaining to suspects' right to legal representation. These rulings further a major difference between the US and Canadian law: Canadian criminal suspects have far less access to legal counsel than suspects in the USA. This paper summarizes these decisions and draws comparisons between Canadian and the US criminal procedure with respect to a suspect's rights to legal representation. We present preliminary data on Canadian citizens' misunderstanding of criminal suspects' right to counsel and also Canadian legal professionals' opinions about the right to counsel. We recommend empirical investigation of the hypothesis that Canadian suspects are more likely than the US suspects to make false confessions. 相似文献

AbstractMost studies that have explored the impact of youth sexual offender treatment on recidivism have not assessed whether effectiveness varies for important subgroups. The present study evaluated the impact of treatment provided by the Griffith Youth Forensic Service (GYFS) on 104 adjudicated youth sexual offenders referred between 2006 and 2012. Sexual, violent and “other” offending outcomes were examined, based on Australian Indigenous cultural heritage and whether the youth resided in a remote community, over an average 2.5-year follow-up timeframe. The findings indicated that GYFS treatment was equally effective for Indigenous and non-Indigenous youth for preventing sexual recidivism and, for youth residing in remote and non-remote locations, for preventing sexual, violent and “other” recidivism. Treatment was less effective in preventing violent and “other” recidivism for Indigenous youth. The core components of the GYFS treatment programme therefore appear particularly well suited for reducing sexual recidivism by Indigenous offenders and those residing in remote communities. 相似文献

Previous research suggests that school-based and electronic victimization have similar negative consequences, yet it is unclear
whether these two contexts offer overlapping or unique associations with adolescents’ adjustment. 802 ninth-graders (43% male,
mean age = 15.84 years), majority being Caucasian (82%), completed measures assessing the prevalence of school and electronic
victimization, as well as self-reports on self-esteem, self-efficacy, anxiety, depressive symptoms, and locus of control.
Results revealed that the majority of adolescents did not report being victimized in either the electronic (75.3%) or the
school (72.9%) context. Victimization in both contexts was associated with lower self-esteem and self-efficacy as well as
higher stress, anxiety, depressive symptoms, and locus of control. Importantly, even after controlling for school-based victimization,
electronic victimization remained as a significant predictor for all outcome measures. Different types of electronic victimization
were also associated with different psychological outcomes. The findings suggest that it is important to distinguish between
victimization contexts and specific adjustment outcomes as school and health officials continue to battle the effects of peer
victimization. 相似文献

Although extensive research analyzes the factors that motivate European parties to shift their policy positions, there is little cross‐national research that analyzes how voters respond to parties’ policy shifts. We report pooled, time‐series analyses of election survey data from several European polities, which suggest that voters do not systematically adjust their perceptions of parties’ positions in response to shifts in parties’ policy statements during election campaigns. We also find no evidence that voters adjust their Left‐Right positions or their partisan loyalties in response to shifts in parties’ campaign‐based policy statements. By contrast, we find that voters do respond to their subjective perceptions of the parties’ positions. Our findings have important implications for party policy strategies and for political representation. 相似文献
