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

Transition teams are often used to help Prime Ministers and Premiers move into their new roles. At the municipal level, the use of transition teams is relatively new. As such, we know little about what these groups do in comparison to federal and provincial transition teams. In this article, we examine mayoral transition teams and find that the increased use of these groups is a reflection of the enhanced organizational complexity of Canadian local government. Additionally, local conditions and candidate experience often dictate the shape and function of transition teams. Overall, we argue that more resources should be devoted to the municipal transition process.  相似文献

ABSTRACT

“America First,” as presented by President Trump, argues for an international strategy that persistently places America’s interests above those of anyone or anything else. Consequently, Trump has reshaped the international perceptions of the United States and has created more difficulties for the U.S. in coordinating of global leaders in resolving complex issues in the world. This essay reflects on how Trump and the United States are viewed internationally, the impacts of Trump’s anti-immigrant and pro-White nationalist rhetoric, Trump’s responses to humanitarian crises around the globe, and the potential impact of Trump’s stance on global climate change. Given these considerations, it is questionable whether “America First” policy has made “America Great Again” in the eyes of the world.  相似文献

Although adolescents often participate in multiple extracurricular activities, little research has examined how the breadth of activities in which an adolescent is involved relates to school-related affect and academic performance. Relying on a large, multi-ethnic sample (N = 864; 55.9% female), the current study investigated linear and non-linear relationships of 11th grade activity participation in four activity domains (academic/leadership groups, arts activities, clubs, and sports) to adolescents’ sense of belonging at school, academic engagement, and grade point average, contemporarily and in 12th grade. Results of multiple regression models revealed curvilinear relationships for sense of belonging at school in 11th and 12th grade, grade point average in 11th grade, and academic engagement in 12th grade. Adolescents who were moderately involved (i.e., in two domains) reported a greater sense of belonging at school in 11th and 12th grade, a higher grade point average in 11th grade, and greater academic engagement in 12th grade, relative to those who were more or less involved. Furthermore, adolescents’ sense of belonging at school in 11th grade mediated the relationship of domain participation in 11th grade to academic engagement in 12th grade. This study suggests that involvement in a moderate number of activity domains promotes positive school-related affect and greater academic performance. School policy implications and recommendations are discussed.  相似文献
