Although national elections in Latin America are now described as reasonably free and fair by international observations teams, electoral processes are still affected by a series of malpractices (unequal access to the media and public resources, registration problems, vote buying). These irregularities negatively affect citizens' trust in elections. In this paper, we analyze the consequences of low trust in elections and exposure to vote buying practices on electoral participation in Latin America. Using data from the 2010 wave of LAPOP surveys, we find that perceiving that the election is unfair reduces the willingness to participate in national elections, but receiving material incentives during the campaign has the opposite effect of increasing electoral participation. We also show that the effect of trust in elections on turnout is larger in countries where voting is not mandatory.  相似文献

This article addresses several issues surrounding the politics of flexibility in Spain. First, it argues that the strategic role of trade unions develop and condition public policies on labour market reform by couching their strategies in terms of the post‐war labour market strategies and structures of the state, especially as governments attempt to move away from established forms of fordist regulation. Hence, second, a broader political and historical perspective is required that understands the complex political dynamics of state‐labour relationships and their structuring over time. The state's role and its labour market presence becomes itself the object of distinct political interventions and calculations by unions, governments and employers. Any discussion of a ‘post‐fordist’ state, determined to increase the flexibility of the labour market, must look at the complex and difficult ‘transitional’ process.  相似文献

POPULATIONS: Whole blood samples from 74 unrelated healthy individuals were collected. The donors' sample included Venezuelan mestizos from various regions of the country, but mostly from the resident population of Caracas City. A Venezuelan mestizo is the offspring of a mating between a native Venezuelan and a person born in Europe, mainly in Spain.  相似文献

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.  相似文献

Allele frequencies of 15 short tandem repeats (STRs) loci included in the PowerPlex 16 kit (Promega Corp., Madison, WI, USA) were obtained from a sample set of unrelated individuals inhabiting Rio Negro (N=593) and Chubut (N=320) provinces of the Argentinean Patagonia. Comparative analyses between our population data and other Patagonian Province (Neuquen) are presented.  相似文献

Niskanen's model has been largely criticized, but it still remains a standard explanation of bureaucracy's behaviour. In this paper we criticize the monopoly power that Niskanen assigns to the bureaucracy. A bilateral monopoly between bureaucrats and politicians might be a much more adequate framework for explaining the bureaucracy's behaviour than Niskanen's original formulation of a perfect discriminating bureaucracy. In a bilateral monopoly model, in no case the type of relationship which holds between the sponsor and the bureau leads to an oversupply of output. Should an excess output occur, it would be a consequence of the political decision-making mechanisms. This result stands in sharp contrast to the Niskanen's model, but, at the same time, it is coherent with the fact that, when the sponsor introduces control and monitoring mechanisms, the sponsor does not pretend to decrease the output but rather to supervise and to reduce the costs of producing the output.  相似文献

To determine the cause of death (as a result of neurologic or nonneurologic complications or accidents) in patients with multiple sclerosis (MS), we reviewed the autopsies of 50 subjects with MS from the Office of the Chief Medical Examiner of Maryland (OCME) between 1982 and 2004. The series included 32 females and 18 males (mean age, 45.8 years; range, 25-69 years) and the causes of death were classified into 3 categories: (A) neurologic complication directly related to MS; (B) nonneurologic complications or other medical causes; and (C) accidents, etc. Of the 50 cases, in 43 there was a history of MS, but in 7 subjects there was not, and the diagnosis was established by neuropathologic examination. In Group A, 21 (42%) cases, deaths were directly related to a neurologic complication; in Group B, 14 (28%) cases were related to the following nonneurologic and medical causes: ASCVD 9 (18%), metabolic disorder 1 (2%), pulmonary embolism 3 (6%), and bronchopneumonia 1 (2%); and in Group C, 15 (30%) cases, deaths were due to trauma, 9 (18%); intoxication, 5 (10%); and thermal injury, 1 (2%). Thus, among the 50 subjects, in 26, deaths occurred naturally; and in 24, from accidents, homicides, suicides, or undetermined causes. Pathologically, the majority of cases showed either chronic inactive (66.7%) or chronic active (15.6%) demyelinating lesions, mainly in the cerebral hemispheres. In some cases, it appears that demyelinating lesions, involving brain regions that regulate cardiorespiratory activity, could be considered as the immediate cause of death, but a large proportion appears to be due to other causes such as accidents and trauma. Thus, it seems likely that taking specific precautions could prevent some deaths in MS.  相似文献

Despite an attempt by its own authors, it is difficult to argue that the influential model of the size of government developed by Meltzer and Richard (1981) has had convincing empirical backing. In this paper, we adapt that model to a model of state government size. The main testable hypothesis is that as income inequality grows, government size (as measured by the percentage of income devoted to government redistribution) grows. We test the model using panel data from the US states from 1979–1991. In contrast to the results found by Meltzer and Richard (1983), we find little evidence to support the model. The results are robust to several model specifications and estimation techniques.  相似文献

ABSTRACT

In recent years there has been a notable increase in the practice of conceptual history in the Ibero-American world. There has been a particular focus on the use of fundamental concepts previous and subsequent to the Independences (1750–1850). This work is a proposal to broaden the temporal framework of analysis, until the Second World War at least. It also suggests the introduction of three central aspects: incorporation of images as a complement to texts in the analysis of concepts; identification of the historical moments at which there occurs a change in the dominant semantic of each concept; and consideration of the Ibero-American sphere, not in isolation but in interaction with the global world. To illustrate this new approach, we provide a case study related to a paradigmatic key concept of modernity: Democracy.  相似文献
