Measuring the accuracy of facial approximations: a comparative study of resemblance rating and face array methods 总被引:1,自引:0,他引:1
The success of facial approximation is thought to depend, at least in part, upon the "accuracy" of the constructed face. However, methods of accuracy assessment are varied and this range in methods may be responsible for the disparate results reported in the literature. The aim of this study was to determine if the accuracy results of one facial approximation were comparable across two different assessment methods (resemblance ratings and simultaneous face array tests using unfamiliar assessors) and if resemblance ratings co-varied with recognition responses. True-positive recognition performance from the facial approximation was poor (21%) while resemblance scores using the same facial approximation were moderately high (3 out of 5 on a five-point scale). These results are not, therefore, consistent and indicate that either different variables are being evaluated by the methods, or the same variable is being examined but with different weight/calibration. Further resemblance ratings tests of the facial approximation to three foil faces from the face array revealed that resemblance scores were similar irrespective of which face was compared, and did not closely correspond with the degree of recognition performance. This was especially the case for isolated comparisons of single faces to the facial approximation. Collectively, these results indicate that resemblance ratings are: (i) insensitive measures of a facial approximation's accuracy; and (ii) inconsistent with results of unfamiliar simultaneous face-array recognition results. These data suggest that familiar and unfamiliar recognition tests should be given increased weight in contrast to current resemblance rating tests. 相似文献

This study investigated whether implicit attitude (IA) and implicit self-concept (ISC) towards transgression predicted daily-life antisocial behaviour (ASB) in institutionalized adolescents. Eighty-seven adolescents completed two Implicit Association Tests (IAT) assessing IA and ISC towards transgression, and reported four times a day during eight days the intensity of their ASB. Staff members concurrently reported the intensity of each adolescent’s ASB. Adolescents filled in the Inventory for Callous-Unemotional Traits and answered a semi-structured interview assessing conduct disorder. Multilevel regression analyses confirmed that adolescents’ ISC towards transgression significantly predicted their self - and staff-reported ASB over and above conduct disorder and callous-unemotional traits. However, adolescents’ IA towards transgression did not predict their ASB. Results indicate that ISC towards transgression is a reliable predictor of daily-life ASB in institutionalized adolescents. These results suggest that transgression-related ISC represents a promising target for ASB prevention in institutionalized adolescents. 相似文献

This article synthesizes the cross‐disciplinary literature on government transparency. It systematically reviews research addressing the topic of government transparency published between 1990 and 2015. The review uses 187 studies to address three questions: (1) What forms of transparency has the literature identified? (2) What outcomes does the literature attribute to transparency? and (3) How successful is transparency in achieving those goals? In addressing these questions, the authors review six interrelated types of transparency and nine governance‐ and citizen‐related outcomes of transparency. Based on the findings of the analysis, the authors outline an agenda for future research on government transparency and its effects that calls for more systematically investigating the ways in which contextual conditions shape transparency outcomes, replicating studies with varying methodologies, investigating transparency in neglected countries, and paying greater attention to understudied claims of transparency such as improved decision making and management. 相似文献

Morality policies evince a much closer relationship to religious doctrines than is the case in other policy areas and hence constitute a most likely case for the observation of religious effects on policymaking and regulatory change. Yet we still lack generally accepted answers to the questions of whether and how religion matters to morality policy. In this paper, we present a theoretical argument that helps to overcome the seemingly contradictory expectations derived from the secularization and religion matters hypotheses. We postulate a bottleneck effect of religious opposition: while religious influence matters most during early stages of the policy process when the problem definition of a moral issue is still in flux, it diminishes during later stages when the issue has made it onto the political agenda. We find evidence of the bottleneck effect in a dataset of policy permissiveness covering 26 countries and spanning 50 years for five morality policies (abortion, euthanasia, homosexuality, pornography, and same‐sex marriage). The data is analyzed via a multilevel model and using Bayesian inference. 相似文献

ABSTRACTThis contribution examines two large-scale land acquisitions on Peru’s northern coast, using a ‘land–water nexus’ approach. The establishment of large sugarcane monocultures resulted in a massive transfer of land and water rights from smallholders to biofuel companies. Using Ribot and Peluso’s theory of access, we demonstrate that this transfer of rights was enabled by the convergence of neoliberal land and water reforms and the presence of the two investors. This constellation (1) altered smallholders’ bundles of rights; and (2) created sharp imbalances that radically changed access to land and water, not only through changing bundles of rights, but also, and maybe more significantly, through widening the gaps between smallholders’ and biofuel companies’ bundles of powers. Using Hall et al.’s powers of exclusion approach, we identify the processes both underpinning and resulting out of the changing access relations analyzed in this study. Changes to Peru’s water governance may accentuate power asymmetries between investors and smallholders, constraining locals’ access to increasingly scarce water. 相似文献

Many debates about engagement with North Korea hinge on theprecise nature of North Korea's foreign economic relations:whether trade and investment are on commercial or non-commercialterms; the extent of illicit activities, and the changing geographicpatterns of North Korea's trade. This article provides an effortto reconstruct North Korea's foreign economic relations, subordinatingour estimates to the discipline of the balance of payments accountingframework. Among the most salient findings for the debate aboutengagement and sanctions is that North Korea's trade and investmenthave continued to increase despite the onset of the nuclearcrisis and a decline in illicit activities. This growth hasoccurred in part because of the growing weight of China andSouth Korea in trade, aid, and investment. We also find thateconomic relations between North and South Korea have a substantiallygreater non-commercial component than those occurring acrossthe China–North Korea border.
