A public agency's capacity to implement policy and achieve valued public outcomes has been a long-running area of research in public administration. Many articles provide theory and empirics regarding the capacity to implement policy, but relatively few examine multiple types of agency capacity within the same analysis. This article develops a model based on the election administration literature in political science and public administration to examine the effects of managerial capacity, financial capacity, and technology on the election management outcome of the residual vote rate in North Carolina election jurisdictions. The results indicate that higher levels of management capacity and technology significantly reduce problems with voting as measured by the residual vote rate. Financial capacity shows a negative association with the residual vote rate but is not significant. The article concludes by discussing how studying election administration provides an important and uniquely good administrative context for developing administrative theory.  相似文献

The Economic Vulnerability Index (EVI) is a well-recognised measure of the structural vulnerability of developing countries and is regularly used and published by the United Nations for cross-country comparison purposes, primarily to review the list of Least Developed Countries (LDCs). However, due to the revisions in methodology occurring over time, the official EVI cannot be used to assess the changes in vulnerability. In this paper, we use two retrospective series of the EVI, based on constant definitions. The real change in vulnerability is thus isolated from the impact of revisions in the design of the index, allowing comparison of the evolution of LDCs and non-LDCs. The implications of the revisions in the EVI design are then discussed.  相似文献

Abstract: Most studies of long‐term chondrocytes survival were for tissue banks. They showed a gradual reduction in the viable chondrocytes percentage as a function of time and ambient temperature, but the samples were harvested under optimal conditions. The aim of our study was to determine the most reliable combination of cartilage source and assay for the in vitro postmortem chondrocyte viability analysis in the conditions that imitate a dead body. Osteochondral cylinders were procured from femoral condyles and talar trochleas of three male donors and stored in the cell culture media at 4 ± 2°C and 23 ± 2°C. The samples were analyzed by a cell viability analyzer and a confocal laser scanning microscope (CLSM) initially 24–36 h after death and then in 4‐week intervals. The results reconfirmed the significant influence of time (p = 0.0002), but not of the temperature (p = 0.237). The largest reproducibility was presented for the knee joint and the CLSM.  相似文献

Tianeptine (Stablon), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a "mushroom of foam" around his mouth. Empty blister packs of Stablon and a suicide note were found next to the body. A liquid-liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 microg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 microg/mL; urine 2.0 microg/mL; liver 23 microg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol.  相似文献

This study identifies predictors of favorable attitudes toward spanking. Analyses were performed with survey data collected from a representative sample of 1,000 adults from Quebec, Canada. According to this survey, a majority of respondents endorsed spanking, despite their recognition of potential harm associated with corporal punishment (CP) of children. The prediction model of attitudes toward spanking included demographics, experiencing or witnessing various forms of family violence and abuse in childhood, and perceived frequency of physical injuries resulting from CP. Spanking was the most reported childhood experience (66.4%), and most violence and abuse predictors were significantly and positively correlated. Older respondents who were spanked in childhood and who believed that spanking never or seldom results in physical injuries were the most in favor of spanking. On the other hand, respondents who reported more severe physical violence or psychological abuse in childhood were less in favor of spanking. Findings are discussed in terms of prevention of CP and family coercion cycle.  相似文献

People vote although their marginal gain from voting is zero.We contribute to the resolution of this paradox by presentinga model for equilibrium configuration of attitudes regardingthe decision to vote. Each individual is seen as an element ofa social network, within which pairs of individuals expressideas and attitudes, exerting mutual influence. We model therole of such networks in propagating the mutual influenceacross pairs of individuals. We show that it may suffice thata small set of individuals have a strong feeling about showingup to vote to generate a significant turnout in elections.  相似文献
