With the 30th anniversary of the policy advisory systems concept on the horizon, it is an appropriate time to reflect further on the concept’s utility, particularly in helping to understand the dynamics of system change and their implications for policy-making. This article provides diachronic analysis of the policy advisory systems in the classic Anglo-Saxon ‘Westminster’ family (Canada, UK, Australia, New Zealand). Analysis focuses on five advisory units: the public service and central agencies, partisan ministerial advisers, external consultants, commissions of inquiry, and select special advisory bodies. The principle research aim is to compare these cases to shed light on advisory system dynamics through identification and analysis of shared and country-specific patterns of PAS change. We argue that the leading dynamics of politicization and externalization often used to characterize how advisory systems change masks idiosyncratic country patterns. We argue that differences in the tempo, intensity, and sequencing of advisory unit (de)institutionalization are clear in these cases and that attention to these dimensions of advisory system change add precision to understanding the organization, operation, and evolution of these systems. 相似文献

What do Americans know about their local judges and how do they know it? One of the central arguments in the debate over judicial elections is whether voters know enough about judicial candidates to make an informed democratic choice. The vast majority of criminal and civil matters in the U.S. begin with and filter through the local state courts. But judicial scholars know little about what explains the variance in voters’ knowledge of their courts and judges. This paper draws on survey data from the 2012 Cooperative Congressional Election Study to investigate the origins of voter knowledge of local judges. A central finding of this study is that rural voters are a lot more knowledgeable about their local judges than are urban voters, ceteris paribus. This finding has significant consequences for the debate over the ways in which states structure their elections for local judges. 相似文献

Mirroring clinical guidelines, recent Performance Validity Test (PVT) research emphasizes using ≥ 2 criterion PVTs to optimally identify validity groups when validating/cross-validating PVTs; however, even with multiple measures, the effect of which specific PVTs are used as criterion measures remains incompletely explored. This study investigated the accuracy of varying two-PVT combinations for establishing validity status and how adding a third PVT or applying more liberal failure cut-scores affects overall false-positive (FP)/-negative (FN) rates. Clinically referred veterans (N = 114; 30% clinically identified as invalid) completing a six-PVT protocol as during their evaluation were included. Concordance rates were calculated across all possible two-and three-PVT combinations at conservative and liberal cutoffs. Two-PVT combinations classified 72–91% of valid (0–4% FPs) and 17–74% of invalid (0–40% FNs) cases, and three-PVT combinations classified 67–86% of valid (0–6% FPs) and 57–97% of invalid (0–24% FNs) at conservative cutoffs. Liberal cutoffs classified 53–86% of valid (0–15% FPs) and 39–82% of invalid (0–30% FNs) cases for two-PVT combinations and 46–75% of valid (3–27% FPs) and 60–97% of invalid (0–17% FNs) cases for three-PVT combinations. Irrespective of whether a two-or three-PVT combination or conservative/liberal cutoffs were used, many valid and invalid cases failed only one PVT (3–68%).Two-PVT combinations produced high FNs and were less accurate than three-PVTs for detecting invalid cases, though variable accuracy was found within both types of combinations based on the specific PVTs in the combination. Thus, both PVT quantity and quality are important for accurate validity classification in research studies to ensure reliability and replicability of findings. Applying more liberal cutoffs yielded increased sensitivity, but with generally higher FPs yielding problematic specificity, particularly for three-PVT combinations. 相似文献

How accurate are survey-based measures of social media use, in particular about political topics? We answer this question by linking original survey data collected during the U.S. 2016 election campaign with respondents’ observed social media activity. We use supervised machine learning to classify whether these Twitter and Facebook account data are content related to politics. We then benchmark our survey measures on frequency of posting about politics and the number of political figures followed. We find that, on average, our self-reported survey measures tend to correlate with observed social media activity. At the same time, we also find a worrying amount of individual-level discrepancy and problems related to extreme outliers. Our recommendations are twofold. The first is for survey questions about social media use to provide respondents with options covering a wider range of activity, especially in the long tail. The second is for survey questions to include specific content and anchors defining what it means for a post to be “about politics.” 相似文献

This paper evaluates the contribution to suicide prevention made by an innovative project, Maytree, a respite center for the suicidal. Maytree offers a distinctive brief period of sanctuary for four nights for suicidal people; within this limited time it aims to provide opportunities through talking, reflecting, and relaxing for reducing the intense feelings that lead to suicidal behavior. The focus of this paper is on evaluating the first 3 years of Maytree's operation, exploring how Maytree works, and its effects on the people who stay there as "guests". This shows that Maytree reaches people who are at significant risk of suicide. Guests report both short term relief and longer term benefits. These changes are understood, through applying crisis intervention theory, as being generated by the opportunities for change in the Maytree approach. Thus, there is the potential for a benign cycle to be established. Maytree's model is different from that of mainstream, statutory services; we conclude that Maytree complements these services and also challenges the values and frameworks of statutory provision in the field of suicide prevention. 相似文献

In Mexico's southern state of Guerrero, rural social and civic movements are increasingly claiming their right to information as a tool to hold the state publicly accountable, as part of their ongoing issue-specific social, economic, and civic struggles. This study reviews the historical, social and political landscape that grounds campaigns for rural democratisation in Guerrero, including Mexico's recent information access reforms and then compares two different regional social movements that have claimed the ‘right to know’. For some movements, the demand for information rights is part of a sustained strategy, for others it is a tactic, but the claim bridges both more resistance-oriented and more negotiation-oriented social and civic movements. 相似文献

For four decades, The Journal of Peasant Studies (JPS) has served as a principal arena for the formation and dissemination of cutting-edge research and theory. It is globally renowned as a key site for documenting and analyzing variegated trajectories of agrarian change across space and time. Over the years, authors have taken new angles as they reinvigorated classic questions and debates about agrarian transition, resource access and rural livelihoods. This introductory essay highlights the four classic themes represented in Volume 1 of the JPS anniversary collection: land and resource dispossession, the financialization of food and agriculture, vulnerability and marginalization, and the blurring of the rural-urban relations through hybrid livelihoods. Contributors show both how new iterations of long-evident processes continue to catch peasants and smallholders in the crosshairs of crises and how many manage to face these challenges, developing new sources and sites of livelihood production. 相似文献

Sex and age are two elements in the establishment of a biological profile for forensic identification. While the pelvic bones are the most ideal structures for sex estimation, the condition of a body is not always ideal due to the nature of death, such as in mass disasters, or postmortem processes. This study utilized CT scans and resultant 3D models of 100 male and 100 female adults of known ages ranging from 18 to 98 years old to collect volumetric and Hounsfield unit measurements of the proximal femur. Equations were created to establish logistic regression models for sex estimation and linear regression models for age estimation. The resultant sex estimation method had an accuracy of 93.5% and utilized the volume of the proximal femur. This study provides three linear regression models for age with an accuracy range of 86%–92% ±12 years. As imaging technologies are increasingly adopted for forensic purposes, the power of 3D data will provide the opportunity for more quantitative and reproducible analyses. The proposed method for sex and age estimation provides a reliable tool that can be utilized in both day-to-day casework and disaster victim identification. 相似文献
