Correlates of loneliness in midadolescence

The present study was designed to assess the relationship between adolescent loneliness and the following factors commonly associated with adult loneliness: attributional style, self-esteem, social anxiety, and social skills. Subjects were 186 ninth-grade students (107 males and 79 females) who were asked to complete seven different paper-and-pencil measures. Data were analyzed by calculating separate stepwise multiple regression equations for the total sample, males and females. Three significant predictors were found for the total sample: student social skills rating scale, self-esteem, and the perception of stability in interpersonal situations (attributional style). A different pattern of predictors emerged for males and females. Loneliness could be predicted for males from three variables: low self-esteem, the perception of uncontrollability in noninterpersonal situations, and self-perceptions of poor social skills. The best multiple predictors of loneliness for the females were self-perceptions of poor social skills, high social anxiety, and stable attributions for interpersonal situations.This study is based on a master's thesis submitted by the first author to Wake Forest University, May 1986.

Social and Political Consequences of Administrative Corruption: A Study of Public Perceptions in Spain

Spain experienced an outbreak of public sector corruption—much of it related to the involvement of regional and local administrators and politicians in the country's urban development boom—that angered the public and sparked calls for government reform. Using data from a 2009 survey that followed these events, the authors examine the association between perceived corruption and the attitudes and behaviors of citizens, including satisfaction with government and democracy, social and institutional trust, and rule‐breaking behaviors. The findings suggest that perceptions of administrative as well as political corruption are associated with less satisfaction, lower levels of social and institutional trust, and a greater willingness to break rules. Although these survey results cannot prove causation, they are consistent with the notion that administrative and political corruption damages the legitimacy of government in the eyes of citizens and weakens the social fabric of democratic society.     

Nuclear DNA typing from ancient teeth

Because of the adverse effects that diagenesis exert on ancient skeletal remains, DNA from these samples is often compromised to the point where genetic typing can be challenging. Nevertheless, robust and reliable methods are currently available to allow successful genotyping of ancient specimens. Here we report nuclear DNA-based methods and typing strategies used to analyze 2 human skeletons from a medieval burial. Reliable DNA nuclear profiles were obtained from teeth, whereas mitochondrial DNA analyses in bones were inconclusive. A complete nuclear mini short tandem repeat profile was obtained from a well-preserved premolar, but only a partial one from the femur. Increasing the sensitivity of the polymerase chain reaction system allowed a full profile from the latter, but the presence of artifacts reinforced the idea that the interpretation of this kind of analysis must be performed with caution. The results presented here also indicate that DNA from dental pieces can be better preserved than from bones, even in the case of well-preserved long bones with thick cortical tissue such as the femurs, and have a better chance of successful genetic typing, probably because of the high degree of protection conferred to the DNA by the enamel.     

Adult Fanniidae associated to pig carcasses during the winter season in a semiarid environment: initial examination of their potential as complementary PMI indicators

Besides the dominant necrophagous dipteran of the families Sarcophagidae and Calliphoridae usually used for post mortem interval (PMI) estimations, species of other families such as Fanniidae have frequently been reported in forensic studies. Though less abundant, these species are prevalent in decomposing carcasses with most reports being anecdotal. In this study we identified adults of the fly family Fanniidae associated to pig carcasses located under different local environmental conditions (sun and shade) in a semiarid area at Mendoza, Argentina during the winter season. We examined the potential of species of this family as indicators of PMI by measuring abundance, time of occurrence and residency time at the carcasses. We identified six species of Fanniidae: Euryomma peregrinum Meigen, Fannia albitarsis Stein, Fannia femoralis Stein, Fannia fusconotata Rondani, Fannia heydenii Wiedemann and Fannia sanihue Domínguez and Aballay. Overall, fly abundance was higher at the sunlit than at the shaded carcass. The most abundant species at the sun was F. fusconotata while at the shaded carcass F. femoralis was the most abundant species. Based on their residency time, however, species with higher potential as PMI indicators seem to be F. heydenii and F. sanihue as their residency time at the carcass was restricted to a short period of the decomposition process. Other species were present throughout most of the decomposition process or in such a low abundance (E. peregrinum) that they were not useful as indicators. These preliminary results indicate that adults of some species of Fanniidae could act as a good complementary indicator species during the winter season. In particular, F. heydenii and F. sanihue should be the focus of further studies which should also expand to other seasons.     

Dental identification by comparison of antemortem and postmortem dental radiographs: influence of operator qualifications and cognitive bias

Dental forensic identifications based on comparison of antemortem and postmortem radiographs provide effective and reliable evidence. There are no standardized procedures for assessing similarities between different types of dental radiographs (e.g. orthopantomograms, bitewings, and periapical radiographs), and the operator's subjective judgment can considerably affect identification. The purpose of this study is to evaluate the potential influence of experts' qualifications, training, and cognitive bias on the accuracy of identification. Seventy-eight differently qualified and experienced experts underwent an identification test. The expert sample was composed of 10 specialists in emergency care (ER), 10 specialists in legal medicine (ML), 20 pregraduate dental students (STU), 12 dentists (DENT), 20 dentists educated in forensic odontology (DENT-TRA), and 6 experienced forensic odontologists (FOR). The simulated cases required participants to assess the possible matching of 42 postmortem intraoral radiographs with 16 antemortem panoramic radiographs. Accuracy and specificity for the different operator groups were as follows: ER, 0.76-0.70; ML, 0.76-0.88; STU, 0.89-0.82; DENT, 0.87-0.97; DENT-TRA, 0.88-0.92; and FOR, 0.97-1. As evidenced by high rates of accuracy and repeatability, the most experienced forensic odontologist consistently outperformed operators less or differently educated and trained, especially for difficult cases. In our sample, the dentists who received additional education in forensic odontology did not necessarily perform better than dentists who had not received this additional education. Some cognitive bias, mainly the so-called observer effect, emerged as a possible source of outcome variability among the operator groups.     

Political Competition and Policy Adoption: Market Reforms in Latin American Public Utilities

This article shows that political competition generates incentives that affect the pace of adoption of market reforms in the context of policy convergence. Previous work shows the effect of financial and technological pressures in promoting policy convergence and the impact of institutional constraints on shaping the pace of policymaking. Controlling for these effects, this article demonstrates the policy effects of political competition and ideological polarization even at a time when ideological policy differences seem to be fading due to policy convergence. This article studies policy adoption using duration analysis for the 18 countries of Latin America during the 1985–2000 period when most of the market reforms in public utilities were adopted.
