Effects of Backpack Carriage on Dual-Task Performance in Children During Standing and Walking

Primary school children perform parts of their everyday activities while carrying school supplies and being involved in attention-demanding situations. Twenty-eight children (8–10 years old) performed a 1-legged stance and a 10 m walking test under single- and dual-task situations in unloaded (i.e., no backpack) and loaded conditions (i.e., backpack with 20% of body mass). Results showed that load carriage did not significantly influence children's standing and walking performance (all p > .05), while divided attention affected all proxies of walking (all p < .001). Last, no significant load by attention interactions was detected. The single application of attentional but not load demand negatively affects children's walking performance. A combined application of both did not further deteriorate their gait behavior.     

Genetic and Environmental Transmission of Political Orientations

This article reports results from the first twin study of adults in the United States that focuses exclusively and comprehensively on political traits. These data allow us to test whether a common set of genetic and environmental influences act upon a broad variety of values, personality traits, and political attitudes. In short, it allows us to empirically investigate whether there are a core set of predispositions that form the basis of our political orientations and, if so, whether these predispositions are shaped by the same environmental and innate forces. The key finding from our analysis is that there are core political predispositions that are rooted in common genetic and environmental influences and that these predispositions are empirically distinct from broader personality traits.     

Long Lives and Old Age Poverty: Social Stratification and Life-Course Institutionalization in Switzerland

This article combines an inter- and an intra-cohort perspective to study economic vulnerability in old age. The theoretical background is given through the combination of a social stratification framework and an institutional perspective emphasizing life course policies. At the macro level, the increase in overall education levels and the implementation of a pension system were the driving forces of the strong decrease in old age poverty over the last three decades. At an individual level, the pathway from low education early in life to economic hardship after retirement is most prominent, corresponding to a social stratification and cumulative disadvantage view.     

Die DPG-Praxis-Studie

All psychotherapeutic methods must be scientifically evaluated. Empirical evaluation of evidence is a prerequisite for acceptance as scientific psychotherapy as well as for payment by health insurance. Currently the psychotherapy methods accepted within the German health system (behavioural therapy, psychodynamic psychotherapy, and analytic psychotherapy) are reviewed by a governmental evaluation committee concerning evidence, necessity and cost-effectiveness. The DPG practice study has basically two aims: 1) to conduct a large naturalistic study to investigate effectiveness, sustainability and economic aspects of psychodynamic and analytic psychotherapy and 2) to offer a framework for psychoanalytic institutes, members, candidates or groups to realize own research ideas by collecting additional data within the study. The present article describes the background, main research questions, structure and design of the DPG practice study with regard to the evaluation questions.     

Facetten eines „deutschen“ Gegenübertragungsproblems

Departing from two case vignettes of psychoanalytic treatments of foreign children of parents who had collaborated with the Germans during the second world war, we are pondering whether there is a specific form of German counter transference defense, making it impossible to allow destructive narcissistic transference offers full of relish through the patients out of the fear that their activation in the analyst might end up in shame and horror as in the previous generations. The nearly complete renunciation to work analytically on the Nazi and Wartime could be described as a secret agreement of the protagonists, finding its justification in keeping out this delightful destruction. The consequences of this abandonment are the disability to establish a solid oedipal position and a regression to the anal world, being characteristic for both postwar German states including much of the analytic work.

Reliability and Validity of a Brief Life Satisfaction Scale with a High School Sample

This study investigated the psychometric properties of a brief life satisfaction scale, the Brief Multidimensional Students’ Life Satisfaction Scale (Huebner et al., 2004a), with a high school age sample. The results revealed preliminary evidence of internal consistency, two-week test–retest reliability, construct validity, and criterion-related validity for research purposes. Expected demographic effects were also obtained. Overall, the findings suggest that the BMSLSS may provide a useful indicator of adolescent life satisfaction in studies in which brevity of measures is an important consideration.     

Helping Behavior as a Subtle Measure of Discrimination Against Lesbians and Gay Men: German Data and a Comparison Across Countries1

To unobtrusively assess attitudes toward lesbians and gay men, the wrong‐number technique was used in a field experiment in Germany. The results are compared to studies using the same paradigm in Switzerland, Great Britain, and the United States. This approach gives a realistic picture of intercultural differences in social behavior against lesbians and gay men. Across studies, the results indicated that homosexuals are less likely to receive help than are heterosexuals. The variation of this effect between countries closely corresponded to the ranking of attitudes toward homosexuality assessed in survey studies. Contrary to survey studies, however, women showed only marginally less negative attitudes toward gay persons than men, when actual helping behavior was used as an attitude index.     

Genetic and environmental determinants of temperament: a comparative study based on Polish and German samples

This study of 1555 adult mono‐ and dizygotic twins reared together estimates the heritability of temperament traits in a Polish and a German sample. We test whether the etiology of temperament traits differs between the two cultures and between different temperament traits. We assessed temperament traits with the Formal Characteristics of Behaviour–Temperament Inventory (FCB‐TI), the Pavlovian Temperament Survey (PTS), the Revised Dimensions of Temperament Survey (DOTS‐R), and the Emotionality–Activity–Sociability Temperament Survey (EAS‐TS). Taking error of measurement into account, genetic sources of variance explained about 50% of the variance of temperament traits. We found neither reliable cultural differences nor robust differences in the etiology of the traits. However, the four questionnaires differed systematically with respect to the proportion of genetic and environmental influences on their scales. Copyright © 2002 John Wiley & Sons, Ltd.     

Farewell to multiculturalism? sharing values and identities in societies of immigration

For critics of multiculturalism, societies of immigration need to strengthen cohesion based on shared democratic values and national identities. This article suggests that democratic values are not a sufficient basis for political cohesion, because they are universal and cannot identify a particular polity toward which one ought to be loyal. Immigrants are always asked to accept a package deal that includes not only democratic values, but also the hegemony of established national cultures. Shared democratic values may also not be strictly necessary for political cohesion. They must be embedded in political institutions and ought to be respected by office holders, democratic politicians, and parties, but democratic states must tolerate that most citizens appear to hold illiberal beliefs including illiberal attitudes toward immigrants. Immigrants are then often asked to profess a commitment to values that citizens do not widely share. If political loyalty, cannot be exclusively based on democratic values, must societies of immigration then ask newcomers to assimilate into a shared national identity? The article argues that this requires, first, a self-transformation of these identities in response to immigration. Instead of regarding shared identities as overriding all other affiliations, democratic states should see them as overarching and overlapping. Different attitudes toward dual nationality illustrate the implication of this suggestion. The article concludes by proposing a catalyst model of multiculturalism as an alternative to the metaphors of the melting pot, the salad bowl, and the mosaic.
