Ideological commitment and posttraumatic stress in former Tamil child soldiers

This study focuses on the impact of present ideological commitment on posttraumatic stress symptoms in former child soldiers living in exile. Eighteen men and two women (aged 25-37), who had joined different Tamil armed groups in Sri Lanka between the ages of 13 and 17 years, participated. The Impact of Event Scale was used to measure posttraumatic symptoms. Qualitative methods were used to investigate the participants' ideological commitment. Participants reported being exposed to many potentially traumatizing events, and had high scores on the Impact of Event Scale. Twenty-five percent of the sample showed strong ideological commitment to the "cause". Ideological commitment at the present seemed to predict better mental health when exposure was less intense and overwhelming. Time had a negative impact on ideological commitment.     

Perceptual transparency in neon color spreading displays

In neon color spreading displays, both a color illusion and perceptual transparency can be seen. In this study, we investigated the color conditions for the perception of transparency in such displays. It was found that the data are very well accounted for by a generalization of Metelli's (1970) episcotister model of balanced perceptual transparency to tristimulus values. This additive model correctly predicted which combinations of colors would lead to optimal impressions of transparency. Color combinations deviating slightly from the additive model also looked transparent, but less convincingly so.     

Structure of conduct problems in adolescence

Scholars disagree about whether adolescent conduct problems (CPs) form a single behavioral syndrome or whether such problems are better conceptualized as different dimensions. The arguments raised by both sides are addressed and tested empirically by analysing data from a large general population sample of Norwegian adolescents (n = 9,342). Confirmatory factor analyses show that a single syndrome of CPs may be subdivided into three highly correlated factors. The first dimension, destructive covert, includes theft and vandalism, whereas the second, nondestructive covert, reflects avoidance of arenas under adult control. The last dimension, overt, includes school opposition and fighting. This three-factor model fits well for both girls and boys, and individuals in their early and late teens. Results from scale analyses are modestly to moderately indicative of a developmental continuum of severity of CPs ranging from nondestructive covert to overt to destructive covert. Taken together the findings imply that both a unidimensional and a multidimensional perspective on CPs are applicable in the general youth population.     

Risk-taking attitudes among young drivers: the psychometric qualities and dimensionality of an instrument to measure young drivers' risk-taking attitudes

Adolescents are proportionately more frequently involved in traffic accidents than are other age groups. A strategy for promoting road safety is to change the attitudes likely to influence driving behavior. However, the lack of valid and reliable instruments to measure risk-taking attitudes makes it difficult to evaluate the effects of measures aimed at changing attitudes among young drivers and their passengers. The present study tested the psychometric qualities of a scale intended to measure adolescents' risk-taking attitudes to driving. The results are based on a self-completion questionnaire survey carried out among 3,942 adolescents and young adults, aged 16-23 years, in Norway in 1998/1999. Using both exploratory and confirmatory factor analyses, 11 dimensions of risk-taking attitudes were identified. Parametric as well as nonparametric methods were applied to test the homogeneity of items within each attitude dimension. The reliability and validity of the dimensions were satisfactory. The attitude dimensions were significantly correlated with self-reported driving behavior, as well as accident frequency. The application of the new measurement instrument in studies aimed at evaluating safety campaigns is discussed.     

Consumer satisfaction and attributions of improvement among fully recovered schizophrenics

As people with serious mental illness are viewed as consumers rather than patients, their views and needs are increasingly seen as essential to the treatment process. The aim of the present study is to add valuable knowledge about how to help patients by reporting what fully recovered schizophrenics, as consumers, had found helpful in their treatment as well as which factors contributed to their recovery. In addition to a semistructured interview, two instruments were used: the "UCLA Social Attainment Survey Premorbid Adjustment Scale" (SASPAS) to measure patients' premorbid adjustment and the "Global Assessment Scale" (GAS) to obtain an assessment of the present general functioning of the subjects. The results showed that a majority of the recovered subjects emphasized their own will-power and the human qualities in their therapists as helpful to them in the process towards recovery. The therapeutic relationships were characterized by the kindling and sustaining of hope in the clients.     

Relational-oriented character analysis

Referring to the diversity of psychoanalysis of today, a position called relational-oriented character analysis is discussed. It is stated that relation and character as concepts refer to different and partly contradictory points of view in psychoanalysis, the first one emphasising mobile, dynamic aspects of personality, the second underlining stable, structural aspects. The principle aim of the article is to argue how the two perspectives can be theoretically combined in an overriding object-relational (two-person) conception and to discuss some implications for analytic technique. Finally, convergences and differences with other positions or schools in contemporary psychoanalysis are suggested.     

Atomistic simulations of cross-slip of jogged screw dislocations in copper

We have performed atomic-scale simulations of cross-slip processes of screw dislocations in copper, simulating jog-free dislocations as well as different types of jogged screw dislocations. Minimum-energy paths and corresponding transition state energies are obtained using the nudged-elastic-band path technique. We find low barriers and effective masses for the conservative motion along the dislocations of elementary jogs on both ordinary {111}<110> and nonoctahedral {110}<110> slip systems. The jogs are found to be constricted and therefore effectively act as pre-existing constrictions; the cross-slip activation energy is thereby dramatically reduced, yielding values in agreement with experiment.     

Effects of Personal Epistemology on the Understanding of Multiple Texts

We examined whether the text understanding of students holding naïve and sophisticated epistemological beliefs was differentially affected by text format, also controlling for effects of gender, word decoding, and prior knowledge on understanding. The participants were 39 Norwegian first-year teacher students, and the topic of reading was attention-deficit hyperactivity disorder (ADHD). It was found that only readers holding sophisticated epistemological beliefs displayed adequate understanding when reading multiple, partly conflicting, texts about ADHD, whereas students holding naïve epistemological beliefs gained better understanding when reading a single textbook-like source with identical content. This finding, however, depended on the level of understanding being measured by the criterial task, with only the task measuring deeper situational text understanding showing an interaction between epistemological beliefs and text format. This study provides evidence that not only knowledge itself, but also personal beliefs about knowledge, may enhance or constrain deeper understanding of multiple texts.
