The Stability of Perceived Pubertal Timing Across Adolescence

It is unknown whether perceived pubertal timing changes as puberty progresses or whether it is an important component of adolescent identity formation that is fixed early in pubertal development. The purpose of this study is to examine the stability of perceived pubertal timing among a school-based sample of rural adolescents aged 11-17 (N=6,425; 50% female; 53% White). Two measures of pubertal timing were used, stage-normative, based on the Pubertal Development Scale, a self-report scale of secondary sexual characteristics, and peer-normative, a one-item measure of perceived pubertal timing. Two longitudinal methods were used: one-way random effects ANOVA models and latent class analysis. When calculating intraclass correlation coefficients using the one-way random effects ANOVA models, which is based on the average reliability from one time point to the next, both measures had similar, but poor, stability. In contrast, latent class analysis, which looks at the longitudinal response pattern of each individual and treats deviation from that pattern as measurement error, showed three stable and distinct response patterns for both measures: always early, always on-time, and always late. Study results suggest instability in perceived pubertal timing from one age to the next, but this instability is likely due to measurement error. Thus, it may be necessary to take into account the longitudinal pattern of perceived pubertal timing across adolescence rather than measuring perceived pubertal timing at one point in time.     

Partisan Attachment and Democracy in Mexico: Some Cautionary Observations

Party identification is a central concept in studies of parties and elections. Drawing from an extensive literature linking the concept of party identification to the understanding of Mexico's electoral politics, this article explores how the Mexican experience informs the understanding of party identification in general, especially in emerging democracies. There, voters' attachments to political parties are usually seen both as essential to and a positive sign of democratic development. This study finds evidence consistent with these arguments in the Mexican case but also identifies aspects of Mexican party identification that are not so clearly supportive of democratic politics; that indeed may delay or even undermine democratization. These findings illustrate the relevance of the Mexican experience to the wider literature on parties and elections, particularly the well-documented relationship between party identifications and democratization.     

Bullying Perpetration,Moral Disengagement and Need for Popularity: Examining Reciprocal Associations in Adolescence

A controlled study of the time-course of breath alcohol concentration after moderate ingestion of ethanol following a social drinking session

This paper evaluates the breath alcohol concentration (BrAC), nausea (feeling of being slightly intoxicated) and subjective driving performance after ingesting a moderate dose of alcohol in the presence of a light meal, which intends to approach a social drinking setting. 119 healthy individuals (69 males and 50 females, aged 21.7+/-3.0) ingested three glasses of wine (95mL each) and their BrAC was determined by an Alcotest 7410 at 15, 30, 45, 60, 90 and 120min post-drinking. 46% of females and no male subjects exceeded a BrAC of 0.25mg/L, the legal limit for driving fixed by some Western countries. 53% of the study population felt nausea during the experimental session and 20% self-reported impairment of their driving skills. In both cases these subjective effects were more pronounced in females. The major determinants of mean BrAC were time post-drinking, gender (male) and body mass index (BMI), all these variables being inversely associated. Females and individuals with a BMI lower than 22.5kg/m(2) were at an increased risk of exceeding the legal limit of BrAC. The feeling of nausea was significantly associated with gender (females), the ingestion of up to 2 drinks on weekdays, and having exceeded a BrAC of 0.25mg/L during the experimental study. The main predictor of self-perception of impaired driving skills was the feeling of nausea, followed by a BrAC in excess of 0.25mg/L. In conclusion, both females and subjects with lower BMI are at an increased risk of exceeding the legal limit of BrAC after moderate alcohol consumption resembling a social drinking setting.     

Commotio cordis as a result of a fight: report of a case considered to be imprudent homicide

The report describes a fatal outcome in a 5-year-old male who died after drinking a fatal dose of ethanol at the party held by his parents. Urine and blood alcohol level of the deceased was 0.4 and 0.5 g/dL, what might explain the sudden death of the child. In addition, the analysis of the boy's hair demonstrated the presence of ethyl glucuronide (EtG), a marker of alcohol consumption; hair EtG concentration levels indicated that the boy might have occasionally imbibed alcohol prior to death. Pathological lesions of the liver observed in histopathology did not contradict such a hypothesis.     

Philosophy of Law Against Sovereignty: New Excesses,Old Fragmentations

The only way of entering the world of ‘fragmented law’ (or ‘societal constitutionalism’) is arguably to make normative fragmentation correspond with constituent excess. As Foucault would say, once we are involved in an ‘epistemic crisis’, we must then modify those systems that organise knowledge in conjunction with the very forms that produce it. This contribution considers some privileged forms of critique and reconstruction beyond normative fragmentation and essentially argues in favour of governance dynamics, as well as for ontological devices engaged in the production of subjectivity.

The resources of corruption: Some reflections from the Italian Case

This article focuses on the resources used in corrupt exchanges and the complex network of actors involved. The empirical analysis is drawn from research into the Italian case, and is based on judicial investigations, a newspaper-based data bank, and interviews. Defining corruption as a market for political rent, the analysis focuses on the “commodities” which flow from the public to the private sectors (in particular, influence over political decisions and information) and those which flow in the opposite direction (such as bribes, influence on the mass media etc.). Resources which corrupt agents use to reduce the costs of “producing” corrupt services are also explored as well as the risks involved in hidden exchange.
