  abstract  = {This study investigates whether number dissimilarities on subject and object DPs facilitate the comprehension of subject-and object-extracted centre-embedded relative clauses in children with Grammatical Specific Language Impairment (G-SLI). We compared the performance of a group of English-speaking children with G-SLI (mean age: 12; 11) with that of two groups of younger typically developing (TD) children, matched on grammar and receptive vocabulary, respectively. All groups were more accurate on subject-extracted relative clauses than object-extracted ones and, crucially, they all showed greater accuracy for sentences with dissimilar number features (i.e., one singular, one plural) on the head noun and the embedded DP. These findings are interpreted in the light of current psycholinguistic models of sentence comprehension in TD children and provide further insight into the linguistic nature of G-SLI.},

  abstract  = {Background: Physical fitness is a key aspect of children's ability to perform activities of daily living, engage in leisure activities, and is associated with important health characteristics. As such, it shows multi-directional associations with weight status as well as executive functions, and varies according to a variety of moderating factors, such as the child's gender, age, geographical location, and socioeconomic conditions and context. The assessment and monitoring of children's physical fitness has gained attention in recent decades, as has the question of how to promote physical fitness through the implementation of a variety of programs and interventions. However, these programs and interventions rarely focus on children with deficits in their physical fitness. Due to their deficits, these children are at the highest risk of suffering health impairments compared to their more average fit peers. In efforts to promote physical fitness, schools could offer promising and viable approaches to interventions, as they provide access to large youth populations while providing useful infrastructure. Evidence suggests that school-based physical fitness interventions, particularly those that include supplementary physical education, are useful for promoting and improving physical fitness in children with normal fitness. However, there is little evidence on whether these interventions have similar or even greater effects on children with deficits in their physical fitness. Furthermore, the question arises whether these measures help to sustainably improve the development/trajectories of physical fitness in these children. The present thesis aims to elucidate the following four objectives: (1) to evaluate the effects of a 14 week intervention with 2 x 45 minutes per week additional remedial physical education on physical fitness and executive function in children with deficits in their physical fitness; (2) to assess moderating effects of body height and body mass on physical fitness components in children with physical fitness deficits; (3) to assess moderating effects of age and skeletal growth on physical fitness in children with physical fitness deficits; and (4) to analyse moderating effects of different physical fitness components on executive function in children with physical fitness deficits. Methods: Using physical fitness data from the EMOTIKON study, 76 third graders with physical fitness deficits were identified in 11 schools in Brandenburg state that met the requirements for implementing a remedial physical education intervention (i.e., employing specially trained physical education teachers). The fitness intervention was implemented in a cross-over design and schools were randomly assigned to either an intervention-control or control-intervention group. The remedial physical education intervention consisted of a 14 week, 2 x 45 minutes per week remedial physical education curriculum supplemented by a physical exercise homework program. Assessments were conducted at the beginning and end of each intervention and control period, and further assessments were conducted at the beginning and end of each school year until the end of sixth grade. Physical fitness as the primary outcome was assessed using fitness tests implemented in the EMOTIKON study (i.e., lower body muscular strength (standing long jump), speed (20 m sprint), cardiorespiratory fitness (6 min run), agility (star run), upper body muscular strength (ball push test), and balance (one leg balance)). Executive functions as a secondary outcome were assessed using attention and psychomotor processing speed (digit symbol substitution test), mental flexibility and fine motor skills (trail making test), and inhibitory control (Simon task). Anthropometric measures such as body height, body mass, maturity offset, and body composition parameters, as well as socioeconomic information were recorded as potential moderators. Results: (1) The evaluation of possible effects of the remedial physical education intervention on physical fitness and executive functions of children with deficits in their physical fitness did not reveal any detectable intervention-related improvements in physical fitness or executive functions. The implemented analysis strategies also showed moderating effects of body mass index (BMI) on performance in 6 min run, star run, and standing long jump, with children with a lower BMI performing better, moderating effects of proximity to Berlin on performance in the 6 min run and standing long jump, better performances being found in children living closer to Berlin, and overall gendered differences in executive function test performance, with boys performing better compared to girls. (2) Analysing moderating effects of body height and body mass on physical fitness performance, better overall physical fitness performance was found for taller children. For body mass, a negative effect was found on performance in the 6 min run (linear), standing long jump (linear), and 20 m sprint (quadratic), with better performance associated with lighter children, and a positive effect of body mass on performance in the ball push test, with heavier children performing better. In addition, the analysis revealed significant interactions between body height and body mass on performance in 6 min run and 20 m sprint, with higher body mass being associated with performance improvements in larger children, while higher body mass was associated with performance declines in smaller children. In addition, the analysis revealed overall age-related improvements in physical fitness and was able to show that children with better overall physical fitness also elicit greater age-related improvements. (3) In the analysis of moderating effects of age and maturity offset on physical fitness performances, two unrotated principal components of z-transformed age and maturity offset values were calculated (i.e., relative growth = (age + maturity offset)/2; growth delay = (age - maturity offset)) to avoid colinearity. Analysing these constructs revealed positive effects of relative growth on performances in star run, 20 m sprint, and standing long jump, with children of higher relative growth performing better. For growth delay, positive effects were found on performances in 6 min run and 20 m sprint, with children having larger growth delays showing better performances. Further, the model revealed gendered differences in 6 min run and 20 m sprint performances with girls performing better than boys. (4) Analysing the effects of physical fitness tests on executive function revealed a positive effect of star run and one leg balance performance and a negative effect of 6 min run performance on reaction speed in the Simon task. However, these effects were not detectable when individual differences were accounted for. Then these effects showed overall positive effects, with better performances being associated with faster reaction speeds. In addition, the analysis revealed a positive correlation between overall reaction speed and effects of the 6 min run, suggesting that children with greater effects of 6 min run had faster overall reaction speeds. Negative correlations were found between star run effects and age effects on Simon task reaction speed, meaning that children with larger star run effects had smaller age effects, and between 6 min run effects and star run effects on Simon task reaction speed, meaning that children with larger 6 min run effects tended to have smaller star run effects on Simon task reaction speed and vice versa. Conclusions: (1) The lack of detectable intervention-related effects could have been caused by an insufficient intervention period, by the implementation of comprehensive and thus non- specific exercises, or by both. Accordingly, longer intervention periods and/or more specific exercises may have been more beneficial and could have led to detectable improvements in physical fitness and/or executive function. However, it remains unclear whether these interventions can benefit children with deficits in physical fitness, as it is possible that their deficits are not caused by a mere lack of exercise, but rather depend on the socioeconomic conditions of the children and their families and areas. Therefore, further research is needed to assess the moderation of physical fitness in children with physical fitness deficits and, in particular, the links between children's environment and their physical fitness trajectories. (2) Findings from this work suggest that using BMI as a composite of body height and body mass may not be able to capture the variation associated with these parameters and their interactions. In particular, because of their multidirectional associations, further research would help elucidate how BMI and its subcomponents influence physical fitness and how they vary between children with and without physical fitness deficits. (3) The assessment of growth- related changes indicated negative effects associated with the growth spurt approaching age of peak height velocity, and furthermore showed significant differences in these effects between children. Thus, these effects and possible interindividual differences should be considered in the assessment of the development of physical fitness in children. (4) Furthermore, this work has shown that the associations between physical fitness and executive functions vary between children and may be moderated by children's socioeconomic conditions and the structure of their daily activities. Further research is needed to explore these associations using approaches that account for individual variance.},

Diese Dissertation verfolgt vor dem Hintergrund der Theorie der Zielsysteme (TDZ) das Ziel der Erstellung anwendungsorientieren Handlungswissens, anhand dessen Interventionsempfehlungen zur Reduzierung des pr{\"a}valenten NEM-Konsums im Nachwuchssport ableitbar sind. Insgesamt wurden sechs Untersuchungen durchgef{\"u}hrt. Die Versuchsteilnehmenden absolvierten in s{\"a}mtlichen Studien eine Variante der lexikalischen Entscheidungsaufgabe. Diese Aufgabe diente der Operationalisierung von automatisch aktivier- und abrufbaren nahrungserg{\"a}nzungsmittelbezogenen Ziel-Mittel-Relationen. In einer Stichprobe von Sportstudierenden zeigte sich, dass NEM mit dem Ziel Leistung assoziiert sind (Studie 1). Unter Ber{\"u}cksichtigung des NEM-Konsums wurde dieses Ergebnis f{\"u}r Nachwuchsathletinnen und -athleten aus dem Breitensport repliziert (Studie 2). Zus{\"a}tzlich konnte in beiden Studien die Bedeutung dieser Ziel-Mittel-Relationen f{\"u}r das Verhalten nachgewiesen werden. In den nachfolgenden Untersuchungen wurden spezifische Ver{\"a}nderungsmechanismen der verhaltensleitenden Ziel-Mittel-Relation aus Leistung und NEM zun{\"a}chst an Sportstudierenden experimentell evaluiert. Durch das Herausstellen der fehlenden leistungssteigernden Wirkung von NEM konnte diese Zielassoziation nicht modifiziert werden (Studie 3). Das Betonen gesundheitssch{\"a}digender Konsequenzen (Studie 4) und das Akzentuieren einer gesunden Ern{\"a}hrung (Studie 5) erwiesen sich demgegen{\"u}ber als geeignet zur Ver{\"a}nderung der Ziel-Mittel-Relation. Das Herausstellen einer gesunden Ern{\"a}hrung f{\"u}hrte deskriptiv bei Nachwuchsathletinnen und -athleten ebenfalls zur Modifikation der Zielassoziation (Studie 6). Die inferenzstatistische Best{\"a}tigung der Ergebnisse dieser Studie steht aufgrund der geringen Testst{\"a}rke der Untersuchung noch aus. Insgesamt verdeutlichen die Ergebnisse, dass die auf Ebene automatischer Kognitionen bestehende und verhaltensleitende Assoziation des Gebrauchs von NEM mit Leistung durch die Akzentuierung gesundheitlicher Perspektiven experimentell ver{\"a}ndert werden kann. Abschließend wird die theoretische und praktische Bedeutung des erstellten Handlungswissen f{\"u}r k{\"u}nftige Interventionsempfehlungen zur Reduzierung des Gebrauchs von NEM diskutiert.},

  abstract  = {Background Vitamin-D-binding protein (VDBP) is a low molecular weight protein that is filtered through the glomerulus as a 25-(OH) vitamin D 3/VDBP complex. In the normal kidney VDBP is reabsorbed and catabolized by proximal tubule epithelial cells reducing the urinary excretion to trace amounts. Acute tubular injury is expected to result in urinary VDBP loss. The purpose of our study was to explore the potential role of urinary VDBP as a biomarker of an acute renal damage. Method We included 314 patients with diabetes mellitus or mild renal impairment undergoing coronary angiography and collected blood and urine before and 24 hours after the CM application. Patients were followed for 90 days for the composite endpoint major adverse renal events (MARE: need for dialysis, doubling of serum creatinine after 90 days, unplanned emergency rehospitalization or death). Results Increased urine VDBP concentration 24 hours after contrast media exposure was predictive for dialysis need (no dialysis: 113.06 +/- 299.61ng/ml, n = 303; need for dialysis: 613.07 +/- 700.45 ng/ml, n = 11, Mean +/- SD, p < 0.001), death (no death during follow-up: 121.41 +/- 324.45 ng/ml, n = 306; death during follow-up: 522.01 +/- 521.86 ng/ml, n = 8; Mean +/- SD, p < 0.003) and MARE (no MARE: 112.08 +/- 302.00ng/ml, n = 298; MARE: 506.16 +/- 624.61 ng/ml, n = 16, Mean +/- SD, p < 0.001) during the follow-up of 90 days after contrast media exposure. Correction of urine VDBP concentrations for creatinine excretion confirmed its predictive value and was consistent with increased levels of urinary Kidney Injury Molecule1 (KIM-1) and baseline plasma creatinine in patients with above mentioned complications. The impact of urinary VDBP and KIM-1 on MARE was independent of known CIN risk factors such as anemia, preexisting renal failure, preexisting heart failure, and diabetes. Conclusions Urinary VDBP is a promising novel biomarker of major contrast induced nephropathy-associated events 90 days after contrast media exposure.},

One issue less discussed is how the construct of ERI translates across different countries and cultures. The purpose of our paper is to describe the sociohistorical context of Germany and implications for the study of ethnic-racial identity in Europe. We discuss the German adaption of the Identity Project, an 8-week school-based ethnic-racial identity exploration intervention developed in the United States. We use this as a concrete example of how we thought through the focal construct of ERI to figure out how and whether it is a salient social identity category for youth in Germany where, in response to the history of racially motivated genocide, discussions of "race" are taboo. Digging into the ways ERI may not be directly transferable to different contexts can help us understand its nature as a socially constructed identity with real-life implications. Our hope with this paper is to further discussion, question our conceptualizations, and acknowledge how a detailed understanding of sociohistorical contexts is needed for the study of ERI.},

  abstract  = {Developing a new product generation requires the transfer of knowledge among various knowledge carriers. Several factors influence knowledge transfer, e.g., the complexity of engineering tasks or the competence of employees, which can decrease the efficiency and effectiveness of knowledge transfers in product engineering. Hence, improving those knowledge transfers obtains great potential, especially against the backdrop of experienced employees leaving the company due to retirement, so far, research results show, that the knowledge transfer velocity can be raised by following the Knowledge Transfer Velocity Model and implementing so-called interventions in a product engineering context. In most cases, the implemented interventions have a positive effect on knowledge transfer speed improvement. In addition to that, initial theoretical findings describe factors influencing the quality of knowledge transfers and outline a setting to empirically investigate how the quality can be improved by introducing a general description of knowledge transfer reference situations and principles to measure the quality of knowledge artifacts. To assess the quality of knowledge transfers in a product engineering context, the Knowledge Transfer Quality Model (KTQM) is created, which serves as a basis to develop and implement quality-dependent interventions for different knowledge transfer situations. As a result, this paper introduces the specifications of eight situation-adequate interventions to improve the quality of knowledge transfers in product engineering following an intervention template. Those interventions are intended to be implemented in an industrial setting to measure the quality of knowledge transfers and validate their effect.},

It used an experimental design to evaluate the effects of the intervention over a period of 30 months. Method: N = 627 German 7th and 8th graders were assigned to a 5-week school-based intervention to reduce media violence use or to a no-intervention control group. Media violence use, normative acceptance of aggression, and aggressive behavior were measured 3 months before the intervention (T1), 7 months post intervention (T2), and at 2 follow-ups 18 (T3) and 30 (T4) months after the intervention. This article focuses on the findings from the 2 follow-ups. Results: Controlling for baseline levels and various demographic covariates, media violence use at T2, T3, and T4 and self-reported physical aggression at T3 were significantly lower in the intervention group, and the indirect path from the intervention to T3 aggression via T2 media violence use was significant. Lower T2 media violence use predicted lower T3 normative acceptance of aggression among participants with lower initial aggression. No effects on nonviolent media use and relational aggression were observed. Conclusion: The findings show that a short class-based intervention can produce lasting changes in media violence use that are linked to a decrease in aggression.},
