This paper analyses government approval in Italy – which has become a key aspect for electoral support in the new party system of the Second Republic – exploring the influence that TV coverage exerts on approval net of traditional accounts of government support. Relying on both aggregate time series and pooled individual-level surveys analyses, it is shown that communication has a sizable impact on government approval. The popularity of Centre-Left and Centre-Right governments is affected evenly by the economy but differently by the news coverage of their activity. People with lower political interest are the most reactive to news coverage of government performance.  相似文献

Diverse sources have constructed a common narrative of individual and isolated responses by countries and their leaders to the global coronavirus pandemic, akin to sálvese quien pueda (every man for himself). This article suggests that this is a simplification of the governance of the COVID-19 pandemic in Peru. Peru's governance story is one of domestic public and private action closely interwoven with crucial elements of transnational administration out of sheer necessity. The struggle against the pandemic has generated a domestic and transnational administrative symbiosis, involving authorities at multiple levels in efforts to fill a series of interconnected domestic, regional, and global governance gaps.  相似文献

High-quality digital three-dimensional (3D) reconstructions of microscopic findings have been used in anatomical and histopathologic research, but their use in forensic pathology may also be of interest. This paper presents an application of these methods to better characterize the pathway of a stab wound of the anterior surface of the heart in a case of suicide. A portion of the heart wall including the stab wound was serially sectioned for microscopic analysis along the full extent of the wound. Histologic sections were digitally acquired, and a 3D reconstruction was created with ImageJ software for 3D computer graphics. This showed a full-thickness wound path extending to the endocardial surface of the left ventricle, curvilinear in appearance. After correction for shrinkage, 3D reconstruction allowed estimation of the dimensions of the myocardial injury and comparison of the appearance of the wound with the suspected knife used. The curvilinear appearance was considered to reflect injury during myocardial contraction. Complete microscopic sectioning and 3D reconstruction may allow virtual sectioning through various orientations and also provide useful forensic information for selected injuries.  相似文献

计划经济时期,我国对社会进行管理的路径是城镇单位制和农村政社合一的村社制.改革开放以后,随着社会的转型,单位制和村社制所覆盖的社会领域开始逐步退缩,继而兴起了以社区为依托的新型社会整合机制,并且各地进行了一些社区制度创新.但由于长期以来存在的城乡二元分割制度,我国社区建设存在着城乡发展不平衡等一系列问题,不利于社会的和谐稳定.当前要积极推进城乡基本公共服务均等化,进行一系列探索来统筹城乡社区建设.  相似文献

Post-mortem diagnosis of chronic alcohol abuse is a challenge for forensic experts due to the lack of pathognomonic morphological findings and often also inadequate background information. Objective methods demonstrating chronic excessive alcohol consumption would therefore be a useful tool for forensic pathologists. In clinical practice, several markers of chronic alcohol abuse have recently been introduced, among which carbohydrate-deficient transferrin (CDT) is the most accepted, but the use of these markers in autopsy has not yet been established. We examined post-mortem stability and possible post-mortem redistribution of CDT and compared two analytical methods, capillary zone electrophoresis and high-performance liquid chromatography. According to our results, CDT remains stable for an appreciable time after death. The results further indicate that CDT is not subject to major post-mortem redistribution.  相似文献

The use of amphetamine and 'ecstasy' (MDMA) has increased exponentially in many European countries since the late nineties, leading to a rapid growth in the number of clinical and forensic analyses. Therefore, a rapid screening procedure for these substances in biological specimens has become an important part of routine toxicological analysis in forensic laboratories. The objective of this study was to evaluate the Cozart amphetamine enzyme-linked immunosorbent assay (ELISA) for the screening of plasma samples and oral fluid samples (collected with the Intercept device). Authentic plasma samples from drivers (n=360) were screened, using an 1:5-fold dilution. True positive, true negative, false positive and false negative results were determined relative to the in-house routine GC-MS analysis. Samples consisted of 144 amphetamine-only positives, 141MDMA/MDA-only positives, and 74 negatives when using the limit of quantitation as the cut-off level for confirmation (10 ng/mL). Using these results, receiver operating characteristic (ROC) curves were generated and optimal cut-off values for the screening assay were calculated. Analysis showed that the ELISA is able to predict the presence of either amphetamine or *MDMA/MDA (*MDMA as its metabolite MDA) in plasma samples with 98.3% sensitivity and 100% specificity at a cut-off value of 66.5 ng/mL d-amphetamine equivalents. A similar analysis was conducted on 216 oral fluid specimens collected from a controlled double blind study. Subjects received placebo or a high (100 mg) or low (75 mg) dose of MDMA. Oral fluid samples were collected at 1.5 and 5.5h after administration. Combined results of the analysis of the high and low dose oral fluid samples indicated a screening cut-off of 51 ng/mL d-amphetamine equivalents with both a sensitivity and specificity of 98.6% (using a LC-MS/MS confirmation cut-off of 10 ng/mL). In conclusion, these data indicate that the Cozart AMP EIA plates constitute a fast and accurate screening technique for the identification of amphetamine and MDMA/MDA positive plasma samples and oral fluid specimens (collected with Intercept. It should be emphasized that method validation should be performed for each type of biological matrix.  相似文献

Whistleblowers, employees of conscience who report on wrongdoing, integrate into their socially useful role one of exposing institutional torpor and bureaucratic incompetence in those official structures responsible for the investigation and correction of wrongdoing. This paper reports on the finding from Australia's largest study into whistleblowers. It shows a crisis of competence in the official capacity of government structures to respond effectively to disclosures made in the public interest.  相似文献
