Images of perpetrators in surveillance video footage are often used as evidence in court. In this study, identification accuracy was compared for forensic experts and untrained persons in facial image comparisons as well as the impact of image quality. Participants viewed thirty image pairs and were asked to rate the level of support garnered from their observations for concluding whether or not the two images showed the same person. Forensic experts reached their conclusions with significantly fewer errors than did untrained participants. They were also better than novices at determining when two high‐quality images depicted the same person. Notably, lower image quality led to more careful conclusions by experts, but not for untrained participants. In summary, the untrained participants had more false negatives and false positives than experts, which in the latter case could lead to a higher risk of an innocent person being convicted for an untrained witness. 相似文献

In this work, two methods were developed to determine herbicides paraquat, glyphosate, and aminomethylphosphonic acid (AMPA) in marijuana samples by capillary electrophoresis. For paraquat analysis, sample was extracted with aqueous acetic acid solution and analyzed by capillary zone electrophoresis with direct UV detection. The running electrolyte was 50 mmol/L phosphate buffer (pH 2.50). For glyphosate and AMPA, indirect UV/VIS detection was used, as these substances do not present chromophoric groups. Samples were extracted with 5 mmol/L hydrochloric acid. The running electrolyte was 10 mmol/L gallic acid, 6 mmol/L TRIS, and 0.1 mmol/L CTAB (pH = 4.7). The methods presented good linearity, precision, accuracy, and recovery. Paraquat was detected in 12 samples (n = 130), ranging from 0.01 to 25.1 mg/g. Three samples were positive for glyphosate (0.15–0.75 mg/g), and one sample presented AMPA as well. Experimental studies are suggested to evaluate the risks of these concentrations to marijuana user. 相似文献

Job satisfaction is an important component of bureaucratic success. In this article, we build on the emerging literature on the five-factor model of personality and argue that basic personality characteristics can help us understand why certain employees are more satisfied with their jobs than others. Multivariate analysis of personality and job satisfaction data from over 1,000 public servants supports this argument. We conclude with a discussion about how personality can add to our theoretical understanding of public personnel management, and help public managers identify applicants who are likely to be satisfied with work in the public sector. 相似文献

A record six African states were awarded a national pavilion at the 2013 Venice Biennale, the premier venue for showcasing a nation's contemporary art, from which Africa has historically been excluded. While first-time participant Angola won the top prize, Kenya's pavilion was the target of bafflement and ire. Using a cultural diplomacy framework that integrates the insights of leading scholars, this research makes concrete recommendations for practitioners vis-à-vis a comparative case study of the two pavilions. Analysis and recommendations consider the interests of a variety of stakeholders and offer insights relevant to Africa and other emerging regions. 相似文献

This article uses Liquid Sky to consider the possibilities of feminist reorientations outside of formal and political orthodoxies and suggests that such disengagements from the dominant are alienated from the utopian rather than re-imagined as transgressive modes of utopian resistance. These disengagements are theorized as a postpunk feminist dystopia: that is, a de-emancipatory system of gendered and aesthetic practices that spatio-sonically shapes queer female sexuality as extrinsic to social and sexual ideals. This dystopia specifically frames the lesbian subject as a bodily terrain of self-estrangement, and names the film's network of alienated corporeal, subcultural, and sonic space. Feminist dystopia ultimately describes female empowerment's precarious position in a sexual and sonic landscape of non-normativity and offers a way to visualize oppositional practices that do not readily correspond to liberation. 相似文献

While U.S. colleges and universities ponder their mission, vision, values, and virtues, researchers at a large, urban, Catholic, patron-identity university actively engaged in empirical assessments of “who we say we are.” In this themed issue, faculty, undergraduate, and graduate students are a research team engaged in quantitative and qualitative analysis of their school's mission identity and mission-driven activities. Results from several sets of studies around student perceptions and impact of mission are presented and discussed. School administrators and those interested in community engagement impacts on students may find these articles useful and informative. 相似文献

ABSTRACTThis contribution takes marriage as the example of a crisis of production and reproduction in rural India. Through the juxtaposition of ethnography separated by six decades, we detail a shift away from land and agriculture as the primary markers of status among the Patidars of central Gujarat, western India, in favour of a hierarchical understanding of international migration. The paper discusses the disconnect between a cultural revolution in favour of migration, and the failure of many to live up to their own cultural standards. More broadly, we reflect on the forces that simultaneously strengthen and dissolve caste inequality in the context of India's uneven growth. 相似文献
