Sex assessment from the carpals bones: discriminant function analysis in a 20th century Spanish sample

Sex assessment is one of the first essential steps in human identification, in both medico-legal cases and bio-archaeological contexts. Fragmentary human remains compromised by different types of inhumation or physical insults may frustrate the use of the traditional sex estimation methods, such as the analysis of the skull and pelvis. Currently, the application of discriminant functions to sex unidentified skeletal remains is steadily increasing. However, several studies have demonstrated that, due to variation in size and patterns of sexual dimorphism, discriminant function equations are population-specific [1,2,5,12,61]. In this study, in order to improve sex assessment from skeletal remains and to establish population-specific discriminant functions, the diagnostic values of the carpal bones were considered. A sample of 100 individuals (50 males and 50 females) of known sex and age was analyzed. They belong to a 20th century identified collection from the Municipal Cemetery of "San José", Granada (Spain) and housed in the Laboratory of Anthropology, Faculty of Medicine, University of Granada (Spain). The age of the individuals ranged between 22 and 85 years. Between four and nine measurements of each carpal bone were performed [41,59]. Discriminant function statistics showed a sex assessment accuracy as high as 97.8%. The results suggest that carpal bones can be used for assessing sex in both forensic and bio-archaeological identification procedures.     

Do Smaller Firms Pay Less in the Caribbean? The Case of Trinidad and Tobago

This article constitutes the first study of the employer size wage effect for a Caribbean country, namely the Republic of Trinidad and Tobago. Using a rich micro-level data set we estimate the firm size wage premium in an empirical model of wage determination. Despite exploring a variety of theories, samples, estimation techniques and tests, we find that, consistent with the empirical literature, larger firms in Trinidad and Tobago pay higher wages than smaller firms, for equally productive workers.     

Municipal Service Delivery: The Role of Transaction Costs in the Choice between Alternative Governance Mechanisms

Service provision by local governments can be delivered using in-house bureaucracies, private firms, and partnerships with other governments or the not-for-profit sector. This production decision has been a major focus of discussion among scholars, practitioners and political agents for the last quarter of a century. The transaction costs framework is an important tool to analyse decisions regarding the production of local services. In this paper, the authors employ this framework to analyse service delivery in Portugal and find that service characteristics and the local political environment play a key role in local officials' choice among the three governance mechanisms to deliver public services.     

Trust in elections,vote buying,and turnout in Latin America

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.     

Fishing from the same schools: Parliamentary recruitment and consociationalism in the first and second Italian republics

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.     

Genetic polymorphisms at four STR loci from the HLA region in a Venezuelan population

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.     

Results of the 2003-2004 GEP-ISFG collaborative study on mitochondrial DNA: focus on the mtDNA profile of a mixed semen-saliva stain

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.     

Genetic attributes of 15 autosomal STRs in the population of two patagonian provinces of Argentina

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.     

A Critical Comment on Niskanen's Model

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.     

Causes of unexpected death in patients with multiple sclerosis: a forensic study of 50 cases

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.
