The Computer-Aided Design Centre has developed a new face recall system which enables a witness to construct the image of a suspect on a television screen. The system currently uses the Photofit library and method of construction. Likenesses of target faces produced by subjects (n=36) using the new system were compared to conventional Photofits produced by a second group of subjects (n=36) of the same targets. There was no difference on any of the three measures employed in the assessed quality of the likenesses produced by Photofit and the CADC System. Both systems tended to produce more recognizable composites when construction was carried out in the presence of the target compared to its absence. Composites made from memory on the initial trial were marginally better with the CADC System than with Photofit. While both systems showed low absolute accuracy, they enjoyed a measure of success in transmitting a likeness of a facial type. It is concluded that while the CADC system shows promise, psychological constraints upon witnesses' powers of recall may place limits on the absolute accuracy achievable with any system of face reconstruction.These experiments were financed by grant No. POL/73 1675/24/3 from the Police Scientific Development Branch of the U.K. Home Office. Points of view expressed in this article are solely those of the authors and do not necessarily reflect the opinions or positions of the funding body. Our gratitude and thanks are due to Tony Kitson and Clive Holloway for their many hours spent developing and operating the CADC system; Jean Shepherd for her skills as a Photofit operator; the Computer-Aided Design Centre; and the MRC Applied Psychology Unit, Cambridge for facilities and subjects. 相似文献
Proportional representation systems affect the extent to which elected legislators exhibit various attributes that allow them to earn a personal vote. The sources of variation in personal vote-earning attributes (PVEA) lie in informational shortcuts voters use under different electoral rules. List type (closed or open) and district magnitude (the number of legislators elected from a district) affect the types of shortcuts voters employ. When lists are closed, legislators' PVEA are of decreasing usefulness to voters as magnitude (and hence the number of candidates on a list) increases. When lists are open, legislators' PVEA are increasingly useful to voters as magnitude increases, because the number of candidates from which voters must choose whom to give a preference vote increases. As predicted by the theory, the probability that a legislator will exhibit PVEA—operationalized as local birthplace or lower-level electoral experience—declines with magnitude when lists are closed, but rises with magnitude when lists are open . 相似文献
This paper examines how the means through which social benefits are delivered—either through a direct government program, or through a tax expenditure program—affects how citizens view social welfare programs and their beneficiaries. Attitudes toward social spending in the United States are strongly conditioned by both racial considerations and perceptions of the deservingness of recipients. We argue that the political cues given by spending conducted through the tax code differ from those given by direct spending in a way that both de-racializes spending attitudes and changes the lens through which citizens evaluate the deservingness of beneficiaries. Through a series of survey experiments, we demonstrate that social benefits delivered through the tax code are less likely to activate racialized thinking than similar or identical benefits delivered directly. This is true, at least in part, because recipients of tax expenditures are perceived as more deserving than recipients of otherwise identical direct spending.
Peer victimization is a well-known national and international problem, contributing to a range of emotional, social, and behavioral consequences. Using structural equation modeling, the authors tested a theoretical model suggesting that psychological distress and student engagement mediate the association between the experience of victimization and concurrent academic achievement. Participants were 469 (46.4 % male, 53.6 % female) 6th to 8th grade students, from randomly selected classrooms in 11 middle schools in a southeastern school district. Structural equation models of the hypothesized effects demonstrated adequate fit to the data, with both symptoms of psychological distress and engagement mediating the relationship between victimization and academic achievement. In general, the results suggest that victimization predicts diminished academic achievement by way of psychological distress and poorer engagement in classroom and academic tasks. However, the direct relationship between victimization and measures of achievement lacked significance across many correlational and path analyses conducted. These findings have implications for researchers and practitioners in understanding how psychological distress and student engagement are associated with the academic performance of students who experience peer victimization. 相似文献
AbstractTrust matters profoundly for many dimensions of political life. In this article we focus on political trust: how the trust or mistrust citizens have toward the political process, politicians and government affects politics. Prior research has shown that political trust influences such crucial dimensions of politics as the basic legitimacy of government, political participation, voting behavior, compliance with government, and reform orientation. In this article, we seek to answer three major questions. First, is political trust declining in Japan? Second, we are interested in exploring the determinants of trust and distrust in politics: why do people lose trust in politics? What kinds of voters lose political trust? Third, we explore the consequences: what happens when people lose trust in government and politics. 相似文献
This study analyzes 127 cases of losses of internal accounting controls in state, local, and nonprofit agencies in North Carolina. The reasons for losses in control are identified and discussed along with ways of preventing such incidents. 相似文献
