Not Worth the Fuss After All? Cross-sectional and Prospective Data on Violent Video Game Influences on Aggression, Visuospatial Cognition and Mathematics Ability in a Sample of Youth

The United States Supreme Court’s recent decision relating to violent video games revealed divisions within the scientific community about the potential for negative effects of such games as well as the need for more, higher quality research. Scholars also have debated the potential for violent games to have positive effects such as on visuospatial cognition or math ability. The current study sought to extend previous literature by using well-validated clinical outcome measures for relevant constructs, which have generally been lacking in past research. Cross-section data on aggression, visuospatial cognition, and math achievement were available for a sample of 333 (51.7 % female) mostly Hispanic youth (mean age = 12.76). Prospective 1-year data on aggression and school GPA were available for 143 (46.2 % female) of those youth. Results from both sets of analysis revealed that exposure to violent game had neither short-term nor long-term predictive influences on either positive or negative outcomes. A developmental analysis of the cross-sectional data revealed that results did not differ across age categories of older children, preadolescents or adolescents. Analysis of effect sizes largely ruled out Type II error as a possible explanation for null results. Suggestions for new directions in the field of video game research are proffered.     

Analysis of the CODIS autosomal STR loci in four main Colombian regions

Genotype polymorphism studies at the 13 loci STRs included in the combined DNA index system [CODIS and PCR-based short tandem repeat loci, in: Proceedings of the Second European Symposium on Human Identification, Promega Corporation, Madison, WI, 1998, pp. 73-88; J. Forensic Sci. 46 (2001) 453] (CODIS: D3S1358, HUMvWA31, HUMFGA, D8S1179 D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, HUMTPOX, HUMCSF1PO and D16S539) were carried out in a sample of 1429 unrelated Colombian individuals belonging to 25 different departments. As many other countries in Latino-America, Colombia shows an important admixture component, basically integrated by Amerindians, European-descendants and African-descendants. Due to the fact that only partial population analyses have been carried out in the country, the main aim of the present analysis is to establish a database of forensic interest based on the widely used CODIS systems covering the main Colombian regions.     

Low‐trust bureaucracy: Understanding the Mexican bureaucratic experience

Latin American bureaucracies are notorious for their inefficiency and opacity, yet there is very little empirical research done on what exactly constitutes the “bureaucratic experience” for citizens and what the costs of bureaucratic dysfunction are. To improve our understanding of this topic, 5 cases of Mexican citizens' encounters with public bureaucracies are used to develop the notion of “low‐trust bureaucracy”: public organisations in which access to services is unreliable and the levels of control towards both citizens and bureaucrats are excessive. This bottom‐up analysis of administrative practices contributes to our understanding of the ineffectiveness of government programmes and services, but also of how bureaucracies in developing countries amplify social inequality rather than function as a social equaliser. Furthermore, this article adds new insights to the existing understanding of administrative burdens as a result of either political tactics or mere benign neglect. The data presented here suggest that structural and intractable characteristics of the broader administrative context, such as authoritarian legacies, can produce behavioural patterns that shift bureaucratic attention away from a fair and efficient service provision.     

Survival of submerged blowfly species and their parasitoids: implications for postmortem submersion interval

Pupal survival of three blowfly species, Chrysomya albiceps, Chrysomya megacephala, and Chrysomya putoria (Diptera: Calliphoridae) and the parasitoid species Nasonia vitripennis (Hymenoptera: Pteromalidae) was studied after the pupae were experimentally submerged in water. Non-parasitized pupae at different developmental stages, 0, 24, 48, and 72 h, and parasitized pupae after 3, 8, 10, and 12 days of development were submerged for 6, 24, 48, or 72 h. Control groups for each pupal developmental stage (parasitized or not), which were not submerged, were also observed in order to compare the adult emergence rates. The survival of white pupae (0 h/age) decreased with time of submergence for all three blowfly species, showing the lowest rates compared with other experimental pupa groups. For the three blowfly species, non-parasitized pupae at 24 and 48 h of age showed survival rates above 60%. However, for pupae at 72 h of age, the survival rates decreased with increased underwater time, with less than 30% survival after 72 h in C. putoria and C. albiceps. The survival of parasitoids inside blowfly pupae that were submerged during their larval stage (3 days/age) decreased with the increase of submergence time. After the parasitoids reached the pre-pupal life stage, the survival was higher for all underwater periods. These observations can be useful in investigations of the decomposition of partially submerged bodies, or in cases of pupae found adhering to decaying flesh, hair, or clothes of corpses that were submerged after the larvae had developed and pupated.     

A new migratory horizon in Central Mexico: 1970-1990

"During the last few decades migration in Central Mexico has undergone important changes. Not only have populations been moving increasingly towards the periphery and decreasingly towards the center, but those originally living in the center are also moving to the immediate periphery. This behavior allows us to claim that Central Mexico is undergoing a process of deconcentration or suburbanization. This study describes the way in which such a process has developed and the situation of geographical entities within that process. Analysis of the new regional configuration takes into account demographic growth and the direction and characteristics of migration in the Mexico City Metropolitan Area and its surrounding states during the last twenty years."

Electronic government from the legal point of view: methods

This paper analyses the working methods used by those jurists who are dedicated to the drafting of proposals for Electronic Government. As will be shown by several practical examples, the best method to perform this task—and, in general, to deal with an innovation such as Electronic Government—consists of proposing, to those interested, a detailed and careful research of the legal activities enabling and improving the reality behind this name. This should be considered as the starting point to building up coherent regulation proposals, in compliance with the fact of the Electronic Government and the rules appropriate to a democratic State.
