This study re-examines the empirical support for one of the most influential explanations of leadership tenure, "selectorate theory," by testing for consistency across key regime categories. The argument made herein is that if the measures are good, the consistency of their relationships should not be limited to particular nominal regime categories, and they should capture the implications of the theory differentiating it from competing theories. Current measures of selectorate theory concepts are wanting on both fronts. I find that the measure used for winning coalition size is correlated with the destabilization of leaders in democracies and the stabilization of leaders in nondemocracies. I also find that the measure of selectorate size exhibits two behaviors inconsistent with the theory: larger selectorates are only stabilizing after the leader has already been in office for an extended period of time; and the effect is only substantial for differentiating between types of military regimes. These findings have five implications: (1) they cast serious doubt on the utility of current measures of selectorate theory; (2) they raise conceptual questions about the treatment of political regimes as vectors or categories; (3) they define substantive, not just statistical, issues that future measures will need to address; (4) they give baselines for re-analysis of the effect of these measures on other implications of interest; and (5) they provide an interesting comment on the comparative politics literature on hybrid regimes and the effect of parliamentary institutions in nondemocratic regimes. 相似文献

Telephone town halls are an increasingly prevalent method for members of Congress (MCs) to communicate with constituents, even while garnering popular criticism for failing to facilitate engagement and accountability. Yet scholars have paid little attention to the events and their effects, and even less to how they might be improved. To remedy this problem, we report on a field experiment in which four MCs joined their constituents in telephone town halls. Overall, participation in an event improved constituents’ evaluations of the format in general, and of the MC in particular. Furthermore, we studied how these events might be improved by evaluating a reform—a single‐topic focus with predistributed briefing materials—designed to enhance deliberative interaction. This reform enhanced effects on opinions of the format without significantly altering effects on attitudes toward the MC. Our results suggest that telephone town halls hold promise for constituents, officeholders, and democratic practice. 相似文献

Police practice of double-blind sequential lineups prompts a question about the efficacy of repeated viewings (laps) of the sequential lineup. Two laboratory experiments confirmed the presence of a sequential lap effect: an increase in witness lineup picks from first to second lap, when the culprit was a stranger. The second lap produced more
errors than correct identifications. In Experiment 2, lineup diagnosticity was significantly higher for sequential lineup
procedures that employed a single versus double laps. Witnesses who elected to view a second lap made significantly more errors than witnesses who chose to stop after one lap or those who were required to view two laps. Witnesses with prior exposure to the culprit did not exhibit a sequential lap effect. 相似文献

Myiasis is defined as an infestation of the organs and/or tissues of human and other animals by fly maggots. Fly species that normally breed in meat or carrion (Diptera: Calliphoridae, Sarcophagidae) may become involved in cutaneous myiasis by colonizing preexisting wounds. Reports of human wound myiasis contracted in hospitals and nursing homes, especially when patients are chronically ill or bed-ridden, are not uncommon across North America and often result in cases of neglect and civil litigation. Based on a case history dealing with this latter situation and circumstances surrounding the treatment of maggot infestation, we designed an experiment to assess the effectiveness of wound cleansing solutions on maggot mortality. Treatments, consisting of four commonly used cleaning solutions (isopropyl alcohol, Dakin's solution, iodine, and hydrogen peroxide) and a control (deionized water), were applied to experimental units (n=5), with each unit consisting of groups of actively feeding Lucilia sericata maggots (Diptera: Calliphoridae). Every 24h, treatments were applied and mortality was assessed for the duration of the study (14 days). Total mean mortality increased over the duration of the experiment, with an initial large increase (10-25%) after the first treatment application, followed by a gradual increase over the remainder of the study. General differences among treatments indicated greatest mean total mortality for Dakin's solution (sodium hypochlorite) (46%), followed by isopropyl alcohol (42%), Betadine (37%), hydrogen peroxide (33%) and lowest mortality for the control (25%); however, no statistically significant differences were observed among treatments and no treatment resulted in 100% maggot mortality. Traditional wound cleansing solutions may not be sufficient for maggot infestations of pre-existing wounds and supplemental treatments may be necessary to effectively treat cases of wound myiasis. 相似文献

Data collection using the life event calendar method is growing, but reliability is not well established. We examine test–retest reliability of monthly self-reports of criminal behavior collected using a life event calendar from a random sample of minimum and medium security prisoners. Tabular analysis indicates substantial agreement between self-reports of drug dealing, property, and violent crime during a baseline interview (test) and a follow-up (retest) approximately 3 weeks later. Hierarchical analysis reveals that criminal activity reported during the initial test is strongly associated with responses given in the retest, and that the relationship varies only by the lag in days between the initial interview and the retest. Analysis of validity reveals that self-reported incarceration history is strongly predictive of official incarceration history although we were unable to address whether subjects could correctly identify the months they were incarcerated. African Americans and older subjects provide more valid responses but in practical terms the differences in validity are not large. 相似文献

The problem of domestic violence is widespread, with research indicating men and women both perpetrate a substantial amount of aggression. However, aggression perpetrated by women is a relatively understudied area compared to aggression perpetrated by men. Additionally, research is needed to determine the correlates of aggression perpetration among women, as this can inform more effective treatment programs. Thus, the current study sought to examine the association between trait anger and impulsivity and the perpetration of physical and psychological intimate partner violence (IPV) and general aggression among women arrested for domestic violence (N = 80). Findings indicated that both trait anger and impulsivity were significantly associated with aggression perpetration and trait anger mediated the relationship between impulsivity and aggression perpetration. Directions for future research and violence intervention programs are discussed. 相似文献
