The authors utilize the two latest ICMA Profile of Local Government Service Delivery Choices surveys to investigate whether the service provision and delivery arrangement information reported in the surveys accurately represents reality and, if not, what factors contribute to generating incorrect or unreliable survey responses. Interviews with practitioners are used to better understand both the accuracy of the survey responses and improvements that could be made to the survey instrument. Results suggest that the ICMA ASD survey data are highly erratic, with more than 70 percent of the cases (N = 70) investigated containing some inaccuracies. A qualitative analysis shows that the majority of the errors appear to be caused by the lack of a clear definition of service provision or by the service titles being too vague or too broad, both of which likely lead to discretion in interpreting survey questions and thus inconsistent answers by individual respondents over time. 相似文献

Contemporary Russian foreign policy demonstrates a dual approach to state sovereignty, using a Westphalian model of sovereignty outside the former Soviet region and a post-Soviet model inside it. This approach performs three functions in contemporary Russian foreign policy: securing Russian national interests at domestic, regional, and international levels; balancing against the United States; and acting as a marker of ‘non-Western’ power identity in an emergent multipolar order. The conflict between these two models increasingly appears to threaten the last of these objectives, however, and as a means of advancing foreign policy objectives the approach thus appears caught in a self-defeating logic. 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

The literature on electoral volatility and the literature on electoral campaigns hold contradictory views on voters switching vote (intention) during the campaign. In this note, we shed new light on this contradiction, making two contributions. First, we investigate the extent to which stable and volatile voters choose the correct party. Second, we distinguish levels of correct voting and the impact of the act of switching on the correctness of the vote. Our analyses of vote-switching in American elections show that, while volatile voters are less likely to vote correctly, they are more likely to switch from an incorrect to the correct party than vice versa. Furthermore, we show that following the campaign more closely makes voters more likely to switch vote (intention) towards the correct party. 相似文献

Research has shown that legal cynicism is pervasive among residents of poor, black neighborhoods. However, controlling for crime rates, these residents call police at higher rates than whites and residents of middle‐class neighborhoods, and ethnographic research suggests that mothers in particular sometimes exact social control over partners and children through police notification. Given these findings, how might researchers better understand how legal cynicism and occasional reliance on police fit together? Drawing on interviews with poor African‐American mothers in Washington, DC, this article develops an alternative conception of cultural orientations about law: situational trust. This concept emphasizes micro‐level dynamism in cultural conceptions of the police, expanding the literature on police trust by emphasizing situational contingency. Mothers deploy at least four alternative strategies that produce moments of trust: officer exceptionalism, domain specificity, therapeutic consequences, and institutional navigation. These strategies shed light on the contextual meanings of safety and legitimacy. 相似文献

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners. 相似文献
