Is informalization equalizing? Evidence from Kinshasa (DRC)

As a consequence of a concatenation of external and internal events, the economy of the Democratic Republic of the Congo (DRC) has informalized to an unprecedented level over the last few decades. A comparison of budget surveys carried out in 1975 and 2004 respectively allows us to ascertain the effect of this process on income inequality and poverty in Kinshasa. We find that the extent of inequality in the capital city of the DRC has remained largely unchanged, which strongly suggests that informalization has been a viable survival strategy for those at the lower-income end of society. Unexpectedly, whereas distinctions such as gender and age lost much of their profiling power in the period considered, other cleavages such as education and geography, which may be assumed to be much more intimately related to the formal sector, continued to play an important role in structuring inequality in Kinshasa’s deeply informalized economy.     

Studies on identity development in adolescence: An overview of research and some new data

The fundamental developmental hypothesis of the identity status model is that as adolescents become older they undergo progressive developmental shifts in identity status: from diffusion to foreclosure or moratorium, from foreclosure to moratorium, and from moratorium to identity achievement. In Study I we give an overview of identity status studies carried out during the period 1966–1993 and show that progressive developmental trends (PDTs) are found in most of these studies. However, they usually involve progressive developmental trends in one of the higher or lower statuses (PDT 1), while only a small minority involve systematic progressive developmental trends, i.e., in at least three statuses (PDT3). It is easier to show progressive developmental trends with separate measures for commitment and exploration than with identity status classification. Study II reports on our own research into relational identity, measured with a new instrument: the Utrecht-Groningen Identity Development Scale (U-GIDS). Application of the U-GIDS allows the construction of four statuses: diffusion, moratorium, closed commitment and achieving commitment. For these four statuses progressive developmental trends were found for relational identity in both one of the higher and one of the lower statuses. The four statuses of our model display exactly the same connection with psychological well-being as the statuses of Marcia's model. The high commitment statuses show the highest level of psychological well-being, followed by the diffusions, while the moratoriums are the least happy. This result offers a new perspective on moratorium as a high identity status. Finally it was found that the differences in psychological well-being among the statuses become greater as adolescents become older.This research was supported by a grant from the Dutch Organization for Scientific Research (NWO) to the Utrecht Study on Adolescent Development (USAD) 1991–1997.Research interests include personality and social development in adolescence.     

Social Support from Parents and Friends and Emotional Problems in Adolescence

In a sample of 2918 adolescents aged 12 to 24 years, the relation between parental and friends' social support was studied, specifically with regard to emotional problems. In addition, age and sex differences were examined. Results indicated that parental and friends' support seem to be relatively independent support systems. Although the degree of perceived support changes in the expected direction (with parental support decreasing and friends' support increasing) during early adolescence, parental support remains the best indicator of emotional problems during adolescence. The effect of friends' support appeared to depend slightly on the level of perceived parental support, with the high parental support group showing a slightly positive effect of friends' support, and the low parental support group showing a negative effect of friends' support.     

The need for performance auditing in the public sector and the best-practice frontier

The article is organized as follows. In Section 2 the arguments for performance auditing in the public sector are reviewed along the lines of the public-choice approach. An international comparison of the functions of supreme auditing institutions (Section 3) reveals that the BelgianRekenhof-Cour des Comptes lags behind, lacking a mandate for performance auditing. In Section 4 the notions of efficiency and effectiveness are clarified. Section S compares the concept of the best-practice frontier with a standard production function. In the public sector one is often confronted with a weak knowledge of the underlying technology. This poses problems of specification for a parametric estimation. Therefore a nonparametric frontier may be recommended. In Section 6 the Farrell method and the free disposal hull are presented. Moreover, when several inputs are transformed into a multiple output (instead of one single homogeneous output), data-envelopment analysis offers a solution (Section 7). These latter methods are also illustrated by an international empirical comparison of the efficiency of public enterprises: postal services in Section 6 and railway companies in Section 7. Some conclusions are reported in the final Section 8.

Conceptual Analysis and Measurement of Adolescent Autonomy

The aim of the present study was to examine the concept of adolescent autonomy. A conceptual analysis of different theoretical perspectives has resulted in an integrative model of attitudinal, emotional, and functional autonomy. Attitudinal autonomy refers to the cognitive process of choosing and defining a goal. Emotional autonomy refers to the affective process of feeling confident about one's own choices and goals. Functional autonomy refers to the regulatory process of developing a strategy to achieve these goals. The empirical value of this model was tested by developing a questionnaire assessing adolescent autonomy. Subjects were 400 adolescents between 12 and 18 years old. Confirmatory factor analyses (LISREL 8) provided evidence for the 3 hypothesized dimensions.     

Assessment of violence risk in youth for juvenile court: relevant factors for clinical judgment

BACKGROUND: Assessment of violence risk in youth for juvenile court needs to be improved. AIM: To determine which items of the Structured Assessment of Violence Risk in Youth (SAVRY) are recorded in pre-trial mental health evaluations and which of these items are associated with the clinical judgment of the risk of violent recidivism. METHOD: A total of one hundred forensic diagnostic juvenile court files were rated with regard to the presence or absence of the thirty SAVRY risk items: ten historical, six contextual and eight individual items, and six protective items. Univariate and multivariate logistic regression analysis were used to examine the relationship between SAVRY risk items and the clinical judgment of violence risk. RESULTS: Most SAVRY-items had been recorded in the files. However, five historical items and the contextual item 'rejection by peers' did not appear in 25-62% of the files. Especially SAVRY items like 'negative-attitudes' and 'psychopathic traits' were the most powerful predictors for clinical judgment of high violence risk. Unexpectedly, historical items played a minor role in clinical judgment. CONCLUSION: Prospective research is needed with the use of SAVRY-items to improve evidence based violence risk assessment in court ordered mental health evaluations of youngsters.

Fast quantification of 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THCA) using microwave-accelerated derivatisation and gas chromatography–triple quadrupole mass spectrometry

A rapid and sensitive determination of cannabinoids in urine is important in many fields, from workplace drug testing over toxicology to the fight against doping. The detection of cannabis abuse is normally based on the quantification of the most important metabolite 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THCA) in urine. In most fields THCA needs to be present at a concentration of exceeding 15 ng/mL before a positive result can be reported.The method described in this paper, combines a 4 min GC–MS/MS method with a fast sample preparation procedure using microwave assisted derivatisation in order to complete the quantification of THCA in urine in 30 min, using only 1 mL of urine.The method is selective, linear over the range 5–100 ng/mL and shows excellent precision and trueness and hence, the estimated measurement uncertainty at the threshold level is small. The method also complies with applicable criteria for mass spectrometry and chromatography. Therefore the method can be used for rapid screening and confirmatory purposes.
