Abstract THIS STUDY is about second‐year students’ self‐assessment in law. Its aims were to test how closely the assessment by the students of their own work matched that of their tutor, to give the students an insight into the “marking process” (which research has shown improves learning), to help the students excel in their examination, to find out whether the male students did better than the female students in their assignment and subsequent examination, and to see how far staff time could be saved. The following were found: there was a high level of agreement between the students’ own marks and those of the tutor, there was generally no significant over‐estimation of assignment marks by the students, the participants did better than the non‐participants in the subsequent examination, the female students did much better than the male students in the assignments as well as the examination (although the participants in general did not do better in their examination than they did in their assignment) and considerable staff time was saved. The findings are discussed in the light of previous research. 相似文献

Clinical evidence suggests that many patients undergo surgery that they would decline if fully informed. Failure to communicate the relevant risks, benefits, and alternatives of a procedure violates medical ethics and wastes medical resources. Integrating shared decision-making, a method of communication between provider and patient, into medical decisions can satisfy physicians' ethical obligations and reduce unwanted procedures. This article proposes a three-step process for implementing a nationwide practice of shared decision-making: (1) create model integration programs; (2) provide legal incentives to ease the transition; and (3) incorporate shared decision-making into medical necessity determinations. 相似文献

In this paper we analyse Stegdetect, one of the well-known image steganalysis tools, to study its false positive rate. In doing so, we process more than 40,000 images randomly downloaded from the Internet using Google images, together with 25,000 images from the ASIRRA (Animal Species Image Recognition for Restricting Access) public corpus. The aim of this study is to help digital forensic analysts, aiming to study a large number of image files during an investigation, to better understand the capabilities and the limitations of steganalysis tools like Stegdetect. The results obtained show that the rate of false positives generated by Stegdetect depends highly on the chosen sensitivity value, and it is generally quite high. This should support the forensic expert to have better interpretation in their results, and taking the false positive rates into consideration. Additionally, we have provided a detailed statistical analysis for the obtained results to study the difference in detection between selected groups, close groups and different groups of images. This method can be applied to any steganalysis tool, which gives the analyst a better understanding of the detection results, especially when he has no prior information about the false positive rate of the tool. 相似文献

Congruence between government policies and citizen preferences is a key element that increases the quality of democracy. While scholars have shown that governments generally adopt ideological positions and propose policies close to citizen preferences, they have neglected to consider whether citizens respond to promises or to actual enactments. The paper addresses this gap in two ways. First, we propose a new measure that captures how close a citizen is on average to the policies enacted by the incumbent government, namely retrospective ideological representation – the ideological distance between the position of a respondent and the incumbent government at the end of its term in office. We show that this measure captures retrospective information associated with governments’ actions and in particular whether the government increases or decreases social spending during its mandate period. Second, we show that retrospective ideological representation has a substantial impact on citizens’ democratic satisfaction and greater than prospective ideological representation – an established measure of congruence – which is the ideological distance between the positions of a respondent and the elected government after an election. 相似文献

Adverse childhood experiences and pessimistic future expectations about college attendance or mortality are established risk factors for problem behaviors among youth. Data were from the National Longitudinal Study of Adolescent to Adult Health (N?=?14,800; 49?% female). Participants were 11–17-years-old at baseline and 24–32-years-old at outcome. Adolescents’ college expectations and fatalistic expectations mediated the effect of childhood adversity on violent behavior in young adulthood. Neither college nor fatalistic expectations were significant mediators in models predicting substance use and nonviolent antisocial behaviors. Although observed mediational effect sizes were small, they survived models that included multiple controls designed to rule-out alternative explanations. Intervening on adversity-exposed adolescents’ college and fatalistic expectations may reduce risk for violent behaviors. 相似文献
