Since segments of the selectorate differently experience costs and benefits from rivalry, the foreign policy choices of leaders reflect these domestic preferences. As a result, shifts in the composition of the domestic coalition of support backing the leader provide a fundamental determinant of rivalry termination. While previous research sought to explore the relationship between domestic political turnover and rivalry termination using regime transitions as a proxy for turnover of the state’s domestic ruling group, in practice this measure exhibits significant disconnection with the quantity of interest. Further, there are alternative pathways through which regime transitions may lead to rivalry termination. I test the relationship using new data from the CHISOLS project, finding that when rivals undergo a change in the source of support that maintains the leader in office, the probability of rivalry termination rises dramatically. I further find that regime transitions have an effect on the probability of rivalry termination that is independent of the effect of ruling coalition turnover. This study thus both asserts the relationship between domestic political turnover and rivalry termination and clarifies the mechanism by which the relationship operates.  相似文献

Many jurisdictions have instituted child protection mediation programs (CPM) for the purposes of reducing the length of children's stays in out‐of‐home care and decreasing court system burden, and numerous studies have shown promising results. However, important implementation and sustainability problems persist. This article presents a case study's findings and retrospectively interprets underlying reasons for challenges the program faced in implementation. Study implications call for a more structured planning process, including early partnership with experienced court‐based evaluators to develop successful marketing and recruitment strategies that may encourage stakeholder endorsement and foster sustainability.  相似文献

The aims of this study were to determine if computer‐measured dynamic features (duration, size, velocity, jerk, and pen pressure) differ between genuine and simulated signatures. Sixty subjects (3 equal groups of 3 signature styles) each provided 10 naturally written (genuine) signatures. Each of these subjects then provided 15 simulations of each of three model signatures. The genuine (N = 600) and simulated (N = 2700) signatures were collected using a digitizing tablet. MovAlyzeR® software was used to estimate kinematic parameters for each pen stroke. Stroke duration, velocity, and pen pressure were found to discriminate between genuine and simulated signatures regardless of the simulator's own style of signature or the style of signature being simulated. However, there was a significant interaction between style and condition for size and jerk (a measure of smoothness). The results of this study, based on quantitative analysis and dynamic handwriting features, indicate that the style of the simulator's own signature and the style of signature being simulated can impact the characteristics of handwriting movements for simulations. Writer style characteristics might therefore need to be taken into consideration as potentially significant when evaluating signature features with a view to forming opinions regarding authenticity.  相似文献

These experiments were designed to determine whether skin debris (desquamated epithelial cells and apparent skin oils) affects gunshot residue (GSR) particle detection on the sticky tape lift samples prepared for scanning electron microscopy (SEM). A dabbing experiment showed that GSR particles accumulate not only on the adhesive surface of the sampler, but also on the epithelial cell surfaces. Samplers were loaded with target GSR followed by dabbing 30 times on the back of a hand. Backscatter electron images were taken at 20 kV and for some at 30 kV of the same areas. The samplers were then treated with a sodium/calcium hypochlorite solution (bleach) to remove skin debris and again imaged in the SEM. Comparison of these images shows more GSR particles will likely be revealed at 30 kV than 20 kV and more particles revealed by the bleach treatment in an automated SEM system.  相似文献

A prevalent view among both scholars and policymakers is that economic sanctions stigmatize and isolate their targets. According to this perspective, the stigma associated with economic sanctions should signal to foreign aid donors that they should be more cautious and restrained in providing assistance to sanctioned states. We test this signaling-based theory via a large-n analysis of the impact that sanctions imposed by the United States and those supported by the United Nations (UN) had on the aid flows of 133 recipient states from 1960–2000. Contrary to expectations, our results indicate that being subject to sanctions supported by the UN does not have a negative effect on target states’ aid flows, and being sanctioned by the United States actually has a positive effect on them. We explore two potential explanations for our puzzling findings based upon donor self-interest and donor altruism via a scoping analysis of eight sanctions cases in which target states received greater than expected aid flows. Our findings suggest that theories based upon donor self-interest represent the most promising explanation for why individual donors may increase their aid to sanctioned states.  相似文献

Scholars have long described the American penal state and welfare state as joined by a common logic of social marginalization. But researchers have only recently begun to explore how the individuals who pass through the carceral system also interact with welfare state programs. Using data from the National Longitudinal Survey of Youth 1979, in this article, I explore how formerly incarcerated individuals make claims on the welfare state and how participation varies across social programs and states, as well as by race, drawing on theories of social welfare rights-claiming and system avoidance. In so doing, I provide the first nationwide estimates of the extent to which previously incarcerated adults use social safety net resources. I find that participation in welfare programs varies with incarceration history, program structure, and race. Rather than finding patterns consistent with system avoidance, I find that previously incarcerated White Americans seem to engage in active rights claiming, participating in public assistance programs more than similarly eligible never-incarcerated counterparts. All formerly incarcerated individuals, however, have limited access to more generous social insurance programs, and the shift to an increasingly employment-based social safety net seems likely to further limit access to the welfare state for the growing population of Americans leaving prison.  相似文献

In recent years, use of substances commonly referred to as ‘legal highs’ has become a significant concern to policy makers and public health officials. Though legislation banning the use and possession of these novel and synthetic drugs often follows the initial media attention and public outcry, potential users may often be unaware of the legislation. A survey including self-reported drug use and perceptions of the legality of various psychoactive substances was administered to 2,346 students in randomly selected classes at a large public university to determine what portion accurately knew four types of novel drugs were locally illegal. Results indicated that numerous potential and current users incorrectly believed that the former ‘legal highs’ remained unrestricted. This sample did include a number of novel drug users; lifetime use of at least one novel drug was reported by 17.1 %, many of which reported using multiple types of novel drugs. Approximately one-third of the overall sample inaccurately believed that Salvia divinorum (34.7 %), K2/Spice (36.5 %), and Mr. Miyagi/Pot-pourri (32.1 %) were legal in the state and over half (50.3 %) inaccurately believed ‘bath salts’ (synthetic cathinones, MDPV, and other synthetic stimulants) remained legal. As these misperceptions have the potential to influence substance use decisions, they may need to be corrected through educational campaigns as widespread as the preceding media coverage that labeled the drug as ‘legal highs.’ Results also indicated that Blacks and previous users of the substances were more likely to hold inaccurate legal beliefs.  相似文献

ABSTRACT

This paper provides an alternative framework that conceptualizes the threat posed by terrorism based on an epidemiological approach that views it as a chronic disease like cancer rather than as a military, ideological, or socio-economic problem. After highlighting the similarities in the causes, behavior, treatments, and challenges of combating terrorism and cancer, this paper presents a staging system policymakers can use to educate the public and allocate counterterrorism resources more efficiently. This approach encourages policymakers to see terrorism for what it is (an all but inevitable facet of modern life that can be managed but never fully eliminated), and not what they wish terrorism to be (a national security problem that can be solved, defeated, or vanquished). It provides policymakers with a useful model to conceptualize the threat and treat terrorism in a comprehensive manner, from preventing future attacks to effectively responding to them when they will inevitably occur.  相似文献

As a result of limited budgets, many treatment programs are forced to operate for extended periods at or beyond their capacity. The resulting pressure and stress on treatment staff can be taxing and lead to serious problems, including job burnout. Although the concept of burnout within other social service professions has been broadly researched, less attention has been given to burnout among drug abuse treatment staff, especially among corrections-based drug treatment staff. The goal of this article is to extend this area of research by exploring the impact of individual factors and organizational factors on burnout. Findings revealed that although a number of factors were related to staff burnout, younger counselor age, lower adaptability, poorer clarity of agency mission, and higher stress were most significant. Ways in which treatment programs might address these issues affecting staff burnout are discussed.  相似文献
