With the exploration of two-dimensional materials such as graphene and new device architectures, HETs are poised to revolutionize the landscape of modern electronics. This study highlights a novel HET structure with a record output current density of 800 A/cm² and a high current gain α, fabricated using a scalable fabrication approach. The HET structure comprises two-dimensional hexagonal boron nitride (hBN) and graphene layers wet transferred to a germanium substrate. The combination of these materials results in exceptional performance, particularly in terms of the highly saturated output current density. The scalable fabrication scheme used to produce the HET opens up opportunities for large-scale manufacturing. This breakthrough in HET technology holds promise for advanced electronic applications, offering high current capabilities in a practical and manufacturable device.}, language = {en} } @misc{MatosFialhoDraganoReuteretal., author = {Matos Fialho, Paula M. and Dragano, Nico and Reuter, Marvin and Metzendorf, Maria-Inti and Richter, Bernd and Hoffmann, Stephanie and Diehl, Katharina and Wachtler, Benjamin and Sundmacher, Leonie and Herke, Max and Pischke, Claudia R.}, title = {Mapping the evidence regarding school-to- work/ university transition and health inequalities among young adults: a scoping review protocol}, series = {BMJ Open}, volume = {10}, journal = {BMJ Open}, number = {12}, issn = {2044-6055}, doi = {10.1136/bmjopen-2020-039831}, abstract = {School-to-work/university transition is a sensitive period that can have a substantial impact on health and health behaviour over the life course. There is some indication that health and health behaviour is socially patterned in the age span of individuals in this transition (16-24 years) and that there are differences by socioeconomic position (SEP). However, evidence regarding this phenomenon has not been systematically mapped. In addition, little is known about the role of institutional characteristics (eg, of universities, workplaces) in the development of health and possible inequalities in health during this transition. Hence, the first objective of this scoping review is to systematically map the existing evidence regarding health and health behaviours (and possible health inequalities, for example, differences by SEP) in the age group of 16-24 years and during school-to-work transition noted in Germany and abroad. The second objective is to summarise the evidence on the potential effects of contextual and compositional characteristics of specific institutions entered during this life stage on health and health behaviours. Third, indicators and measures of these characteristics will be summarised.Methods and analysisWe will systematically map the evidence on health inequalities during school-to-work-transitions among young adults (aged 16-24 years), following the methodological framework proposed by Arksey and O'Malley. The literature search is performed in Ovid MEDLINE, Web of Science, International Labour Organization and National Institute for Occupational Safety and Health, using a predetermined search strategy.

Few studies have examined the role of the family in explaining the association between the family's socioeconomic position and adolescents' self-rated health. The current study aimed to explore whether the association between socioeconomic position and self-rated health was mediated by familial determinants. Methods Using data from wave 2 of the"German Health Interview and Examination Survey for Children and Adolescents" (KiGGS) (1,838 female and 1,718 male 11- to 17-year-olds), linear regression analyses were conducted to decompose the total effects of income, education, occupational status, socioeconomic position index and adolescents' subjective social status on self-rated health into direct effects and indirect effects through familial determinants (family cohesion, parental well-being, parental stress, parenting styles, parental obesity, smoking and sporting activity). Results A significant total effect of all socioeconomic position indicators on self-rated health was found, except for income in male adolescents. In female adolescents, more than 70\% of the total effects of each socioeconomic position indicator were explained by familial mediators, whereas no significant direct effects remained. The most important mediator was parental well-being, followed by family cohesion, parental smoking and sporting activity. In male adolescents, the associations between income, parental education, the socioeconomic position index and subjective social status were also mediated by familial determinants (family cohesion, parental smoking, obesity and living in a single-mother family). However, a significant direct effect of subjective social status remained. Conclusion The analysis revealed how a family's position of socioeconomic disadvantage can lead to poorer health in adolescents through different family practices. The family appears to play an important role in explaining health inequalities, particularly in female adolescents. Reducing health inequalities in adolescence requires policy interventions (macro-level), community-based strategies (meso-level) and programs to improve parenting and family functioning (micro-level).}, language = {en} } @misc{HoffmannSanderWachtleretal., author = {Hoffmann, Stephanie and Sander, Lydia and Wachtler, Benjamin and Blume, Miriam and Schneider, Sven and Herke, Max and Pischke, Claudia R. and Matos Fialho, Paula M. and Schuettig, Wiebke and Tallarek, Marie and Lampert, Thomas and Spallek, Jacob}, title = {Moderating or mediating effects of family characteristics on socioeconomic inequalities in child health in high‑income countries - a scoping review}, series = {BMC Public Health}, volume = {22}, journal = {BMC Public Health}, issn = {1471-2458}, doi = {10.1186/s12889-022-12603-4}, pages = {1 -- 14}, abstract = {Background: By explaining the development of health inequalities, eco-social theories highlight the importance of social environments that children are embedded in. The most important environment during early childhood is the family, as it profoundly influences children's health through various characteristics. These include family processes, family structure/size, and living conditions, and are closely linked to the socioeconomic position (SEP) of the family. Although it is known that the SEP contributes to health inequalities in early childhood, the effects of family characteristics on health inequalities remain unclear. The objective of this scoping review is to synthesise existing research on the mediating and moderating effects of family characteristics on socioeconomic health inequalities (HI) during early childhood in high-income countries. Methods: This review followed the methodology of "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews". To identify German and English scientific peer-reviewed literature published from January 1st, 2000, to December 19th, 2019, the following search term blocks were linked with the logical operator "AND": (1) family structure/size, processes, living conditions, (2) inequalities, disparities, diversities, (3) income, education, occupation, (4) health and (5) young children. The search covered the electronic databases PubMed, PsycINFO, and Scopus. Results: The search yielded 7,089 records. After title/abstract and full-text screening, only ten peer-reviewed articles were included in the synthesis, which analysed the effects of family characteristics on HI in early childhood. Family processes (i.e., rules /descriptive norms, stress, parental screen time, parent-child conflicts) are identified to have mediating or moderating effects. While families' living conditions (i.e., TVs in children's bedrooms) are suggested as mediating factors, family structure/size (i.e., single parenthood, number of children in the household) appear to moderate health inequalities. Conclusion: Family characteristics contribute to health inequalities in early childhood. The results provide overall support of models of family stress and family investment. However, knowledge gaps remain regarding the role of family health literacy, regarding a wide range of children's health outcomes (e.g., oral health, inflammation parameters, weight, and height), and the development of health inequalities over the life course starting at birth.}, language = {en} } @misc{HerrDiehlSchneideretal., author = {Herr, Raphael and Diehl, Katharina and Schneider, Sven and Osenbruegge, Nina and Memmer, Nicole and Sachse, Steffi and Hoffmann, Stephanie and Wachtler, Benjamin and Herke, Max and Pischke, Claudia R. and Novelli, Anna and Hilger-Kolb, Jennifer}, title = {Which Meso-Level Characteristics of Early Childhood Education and Care Centers Are Associated with Health, Health Behavior, and Well-Being of Young Children?

This scoping review aims to provide an overview of the association between meso-level characteristics (MLCs) of ECEC centers with children's health, health behavior, and wellbeing. Five databases were searched for quantitative and qualitative research articles published in English or German since 1 January 2000 on health, health behavior, and wellbeing of children aged 0 to 6 years considering MLCs of ECEC centers. Two authors screened 10,396 potentially eligible manuscripts and identified 117 papers, including 3077 examinations of the association between MLCs and children's health indicators (Kappas > 0.91). Five categories of MLCs were identified: (1) structural characteristics, (2) equipment/furnishings, (3) location, (4) facilities/environment, (5) culture/activities/policies/practices, and 6) staff. Only very few studies found an association of MLCs with body weight/obesity, and general health and wellbeing. Especially physical activity and mental health were related to MLCs. In general, the location (rural vs. urban, neighborhood status) seemed to be a relevant health aspect. MLCs of ECEC centers appeared relevant for child health indicators to different degrees.

Design Scoping review. Study selection Relevant literature was systematically searched following the methodological framework proposed by Arksey and O'Malley. Ovid MEDLINE and Web of Science, and websites of the International Labour Organization and National Institute for Occupational Safety and Health were searched, using a predetermined search strategy. Articles in English or German published between 1 January 2000 and 3 February 2020 were considered. Data extraction To collect the main information from the selected studies, a data extraction spreadsheet was created. Data were summarised and grouped into five health outcomes and five institutional contexts (school, vocational training, university, work, unemployment). Results A total of 678 articles were screened for inclusion. To be able to draw a picture of the development of various health outcomes over time, we focused on longitudinal studies. Forty-six prospective studies mapping health-related outcomes during STWT were identified. Higher family socioeconomic position (SEP) was associated with higher levels of health behaviour and lower levels of health-damaging behaviour, but there was also some evidence pointing in the opposite direction. Disadvantaged family SEP negatively impacted on mental health and predicted an adverse weight development. There was limited evidence for the outcomes physical/somatic symptoms and self-rated health. Meso-level characteristics of the institutional contexts identified were not systematically assessed, only individual-level factors resulting from an exposure to these contexts, rendering an analysis of effects of contextual and compositional characteristics on health and health behaviours impossible.

Little is currently known about the pathways by which family SEP is influencing child health and health-related behaviour, and which role family characteristics play. The scoping review therefore aims to screen the international literature on the mediating and moderating effects of contextual and compositional family characteristics on socioeconomic health risks of pre-school children in developed countries. Methods: Following the PRISMA guidelines for scoping reviews, three online databases (Pubmed, PsycINFO, and Scopus) will be searched for literature in English or German published after year 2000. The two-step data screening approach and the subsequent data extraction will be conducted independently by two researchers in consideration of specific criteria and a previously tested standardized data extraction form. Due to the broad research question at hand, various study designs (e.g. cross-sectional, intervention, cohort studies, and qualitative studies), SEP measures (e.g. education, income) and compositional (e.g. family size, migration) or contextual (e.g. parenting, housing) family characteristics influencing children's health will be included. Since diverse definitions and reporting formats of subjective health, health behaviour, well-being, and diseases will be considered, a substantial heterogeneity in outcome measures focusing on the age group of 0-6 years is expected. Thus, a narrative synthesis of the findings will be performed according to the Centre for Reviews and Dissemination framework. Ethics and dissemination: Because no primary data will be collected, ethical clearance will not be required. Dissemination will include peer-reviewed publications and conferences.}, language = {en} }
