This paper studies the distributive impact of institutional change in developing countries. In such economies, property rights systems may preserve the interests of an influential minority, who can control key-markets, access to assets and investment opportunities, especially if they enjoy disproportionate political power. We test this hypothesis using cross-section and panel data methods on a sample of low- and middle-income economies from Africa, Asia and Latin America. Results suggest that: (a) increasing property rights protection increases income inequality; (b) this effect is larger in low-democracy environments; (c) some countries have developed political institutions capable of counterbalancing this effect. 相似文献

Eusammenfassang Wenngleich sich Europ?isierung in der Politikwissenschaft noch zu keinem eigenst?ndigen Theoriestrang verdichtet hat, haben
die Aktivit?ten in diesem Forschungsbereich in den vergangenen Jahren erheblich zugenommen. Nationalstaatliche Ver?nderungsprozesse
fest im Blick, brachten diese Arbeiten einen lange vernachl?ssigten Bereich zurück auf die Forschungsagenda: die Rückwirkung
der europ?ischen Integration auf den Nationalstaat. Dieser Bericht spiegelt den aktuellen Stand der Europ?isierungsdebatte
wider und umfasst sowohl Prozesse der Europ?isierung von EU-Mitgliedsstaaten als auch von (potenziellen) Beitrittskandidaten.
Darüber hinaus werden dringliche Forschungsfragen zukünftiger Europ?isierungsstudien aufgeworfen, um einen bescheidenen Beitrag
zur wissenschaftlichen Debatte zu leisten. 相似文献

Commotio cordis is a clinic-pathological syndrome related to sudden death in young people involved in sports activities. It has been described, mainly, in athletes without previous cardiac anomalies who received a minor blow to the chest which produces ventricular fibrillation and cardiac arrest in the absence of structural damage to the ribs, sternum, or heart. There are few reported cases of commotio cordis associated with violent, non-sports related actions, which are commonly considered to be imprudent homicides. We present the case of a 20-year-old man, who was kicked in the chest during a fight; he suddenly collapsed although advanced cardio-respiratory resuscitation started shortly. Autopsy showed no cardiac lesions concluding that death was due to commotio cordis (blunt trauma to the chest). Toxicological analysis determined the presence of 5.14 mg/L benzoylecgonine in blood. On the basis of medico-legal investigation, the official prosecution considered the death to be imprudent homicide and the aggressor was sentenced to 4 years in prison. We emphasize the importance of the knowledge of the death circumstances through the witnesses’ testimony, prior to beginning the autopsy, to confirm this important medico-legal diagnosis. Arrhythmogenic effects of cocaine and its contribution in the production of these deaths are also exposed. 相似文献

In a Nature paper of 2010, the concern was raised that intra-individual mtDNA variation may be more pronounced than previously believed, in that heteroplasmies are common and vary markedly from tissue to tissue. This claim taken at face value would have considerable impact on forensic casework. It turns out however that the employed technology detected the germ-line variation relative to the reference sequence only incompletely: on average at least five mutations were missed per sample, as an in silico reassessment of the data reveals. Before one can really set out to access to entire mtDNA genome data with relative ease for forensic purposes, one needs careful calibration studies under strict forensic conditions—or might have to wait for another generation. 相似文献

The occurrence of complete decapitation as a consequence of car accident is an extremely rare event. This fatality is generally seen in pedestrians run over by trains and also in motorcyclists who impact against the tailboard of trucks. Moreover, complete transection of pedestrians and occupants of cars has been described in road accidents especially in case of vehicles traveling at a high speed. We present a case of decapitation with complete degloving injury of the neck in a patient involved in a traffic accident, and we briefly discuss the possible mechanisms producing this injury. 相似文献

Stress-induced cardiomyopathy (SICM) is characterized by transient systolic dysfunction of the apical and/or midventricular myocardial segments in the absence of obstructive coronary artery disease and is unique in that it can manifest itself after acute emotional stress. Excessive amounts of catecholamines released from sympathetic nerve endings as well as from the adrenal medulla under stressful conditions are considered to produce intracellular Ca(2+) overload and cardiac dysfunction through the β(1)-adrenoceptor signal transduction pathway. We describe the clinical and pathomorphological findings in two stress-induced cardiomyopathy fatal cases. Levels of catecholamines and their metabolites in urine samples were assessed too. Morphological patterns seen in SICM result from the complex interplay between sympathetic innervations, β-receptor density and function and catecholamine sensitivity. 相似文献

Several ink dating methods based on solvents analysis using gas chromatography/mass spectrometry (GC/MS) were proposed in the last decades. These methods follow the drying of solvents from ballpoint pen inks on paper and seem very promising. However, several questions arose over the last few years among questioned documents examiners regarding the transparency and reproducibility of the proposed techniques. These questions should be carefully studied for accurate and ethical application of this methodology in casework. Inspired by a real investigation involving ink dating, the present paper discusses this particular issue throughout four main topics: aging processes, dating methods, validation procedures and data interpretation. This work presents a wide picture of the ink dating field, warns about potential shortcomings and also proposes some solutions to avoid reporting errors in court. 相似文献

This study examined the prevalence of mental health and substance abuse disorders and service utilization among a racially and ethnically diverse group of foster youth. Self-report data on symptoms and service receipt were used to identify whether groups of adolescents defined by their race and ethnicity were equally likely to receive services given the presence of a mental health or substance use disorder. Study findings showed that Caucasians are more likely to receive mental health services than African Americans. Race was not a significant predictor of accessing substance abuse services. Hispanic ethnicity was not a predictor of receipt of mental health or substance abuse treatment services. Implications for future research, practice, and policy are discussed. 相似文献

Direct influence over communication media is a potent resource during electoral campaigns, and politicians have an incentive to gain control of the airwaves to advance their careers. In this article, we use data on community radio license applications in Brazil to identify both the causal effect of incumbency on politicians’ ability to control the media and the causal effect of media control on their future electoral prospects. Using a regression discontinuity design, we compare city council candidates who barely won or barely lost an election, showing that incumbency more than doubles the probability of an application’s approval by the Ministry of Communications. Next, using genetic matching, we compare candidates who acquired community radio licenses before an election to similar politicians who did not, showing that a radio station substantially increases one’s vote share and probability of victory. These findings demonstrate that media control helps entrench local political power in Brazil. 相似文献
