BT - The Role of Depressive Symptoms, Dysfunctional Attitudes, and Gender in Early Adolescent Stress Generation JF - Journal of early adolescence N2 - To provide further insight into stress generation patterns in boys and girls around puberty, this study investigated longitudinal reciprocal relations between depressive symptoms, dysfunctional attitudes, and stress generation, the process by which individuals contribute to the occurrence of stress in interpersonal contexts (e.g., problematic social interactions) or in noninterpersonal contexts (e.g., achievement problems). A community sample of N = 924 German children and early adolescents (51.8% male) completed depressive symptoms and dysfunctional attitudes measures at T1 and again 20 months later (T2). Stressful life events were reported at T2. Dysfunctional attitudes were unrelated to stress generation. Interpersonal, but not noninterpersonal, dependent stress partially mediated the relationship between initial and later depressive symptoms, with girls being more likely to generate interpersonal stress in response to depressive symptoms. Findings underscore the role of interpersonal stress generation in the early development of depressive symptomatology, and in the gender difference in depression prevalence emerging around puberty.

JF - Public policy and administration N2 - An ever-increasing number of policy problems have come to be interpreted as representing a particular type of intractable, ill-structured or wicked policy problem. Much of this debate is concerned with the challenges wicked problems pose for program management rather than policy analysis. This article, in contrast, argues that the key challenge in addressing this type of policy problems is in fact analytical. Wicked policy problems are difficult to identify and interpret. The knowledge base for analysing wicked policy problem is typically fragmented and contested. Available evidence is incomplete, inconclusive and incommensurable. In this situation, the evidentiary and the interpretative elements of policy analysis become increasingly indistinguishable and inseparably intertwined. The article reveals the problems this poses for policy analysis and explores the extent to which the consolidation, consensualization and contestation of evidence in policy analysis offer alternative procedural paths to resolve these problems.

BT - What Would a "Perfect Therapy" Look Like? JF - Die Rehabilitation : Zeitschrift für Praxis und Forschung in der Rehabilitation N2 - Hauptziel Adipositas ist eine der Hauptindikationen in der Kinder- und Jugend-Rehabilitation. Für ältere Jugendliche und junge Erwachsene fehlen altersspezifische Therapieangebote fast vollständig. Ziel war es die Wünsche bezüglich der Inhalte und Methoden einer „perfekten Therapie“ im Rahmen eines Rehabilitationsaufenthalts zu untersuchen. Methode Im Rahmen der YOUTH-Studie wurden 147 adipöse Jugendliche und junge Erwachsene beiderlei Geschlechts (zwischen 15 und 21 Jahren) mithilfe eines standardisierten Fragebogens befragt. Ergebnis Insgesamt zeigten sich relativ wenige alters- und geschlechtsspezifische Unterschiede. Interdisziplinär geleitete, koedukative Gruppen mit Elterneinbindung wurden gewünscht. Wichtige Themen waren gesunde Ernährung sowie psychosoziale Aspekte. Auch der Prävention von Rückfällen wurde eine hohe Relevanz zugeschrieben. Schlussfolgerung Psychosoziale Aspekte und die Vorbereitung auf mögliche Rückfallsituationen sollten integraler Bestandteil der Therapie sein. N2 - Principal objective Obesity is a major indication for pediatric and adolescent-rehabilitation. Age-specific therapies for „emerging adults“ are lacking. The aim was to examine the patients’ preferences with respect to the contents and methods of the „perfect therapy“ within an inpatient setting. Method In the context of the YOUTH study 147 obese male and female adolescents (aged 15–21 years) filled in standardized questionnaires. Results Overall little age- and gender-specific differences were observed. The participants expressed a preference for interdisciplinary coordinated and coeducational group approaches with involvement of the parents. Major topics were healthy nutrition and psychosocial aspects. Prevention of relapses is considered as important as well. Conclusion Psychosocial aspects and preparing coping with risk situations should be an integral part of treatment programs.

We investigate whether this leads readers to look directly at a word but not pay attention to it. We used a gaze-contingent boundary paradigm to dissociate parafoveal and foveal information (e.g., the word phone changed to scarf once the reader's eyes moved to it) and asked questions about the sentence to determine which one the reader encoded. When the word was skipped or fixated only briefly (i.e., up to 100 ms) readers were more likely to report reading the parafoveal than the fixated word, suggesting that there are cases in which readers look directly at a word but their minds ignore it, leading to the illusion of reading something they did not fixate.

Some of these interactions actually arise from the presence of unspecified nonlinear main effects and statistically dependent covariates in the statistical model. Importantly, such nonlinear main effects may be compatible (or, at least, not incompatible) with the current theoretical framework. In the present literature, this issue has only been studied in terms of correlated (linearly dependent) covariates. Here we generalize to nonlinear main effects (i.e., main effects of arbitrary shape) and dependent covariates. We propose a novel nonparametric method to test for ambiguous interactions where present parametric methods fail. We illustrate the method with a set of simulations and with reanalyses (a) of effects of parental education on their children’s educational expectations and (b) of effects of word properties on fixation locations during reading of natural sentences, specifically of effects of length and morphological complexity of the word to be fixated next. The resolution of such ambiguities facilitates theoretical progress.

This is pursued by applying a vector error correction model and an impulse response analysis using monthly price data for the period 2000-2015. Our analysis considers transmission of price shocks across different market levels, including from the international and domestic wheat grain markets at the upstream to the domestic wheat bread market at the downstream of the value chain. The empirical findings indicate that significant cointegration exists across prices of the different market stages. There is a transmission from international prices to domestic prices at downstream markets, in particular to flour and bread prices. Prices at upstream markets are largely influenced by the domestic wholesale market. In general, the speed of adjustment is quite slow with a half-life of about one year for restoring the equilibrium price relationship. As price margins between the different market stages in the value chain have substantially decreased in the last 15 years, higher transmission, and thus exposure to international market shocks, can be expected in the future. The results also show that causal relationships exist between prices at different market stageswith the wholesale market identified as the key market level where prices and price expectations are formed.

Using 26 long-term grassland and forest experimental ecosystems, we demonstrate that biodiversity-ecosystem functioning relationships strengthen mainly by greater increases in functioning in high-diversity communities in grasslands and forests. In grasslands, biodiversity effects also strengthen due to decreases in functioning in low-diversity communities. Contrasting trends across grasslands are associated with differences in soil characteristics.
