Gain-assisted superluminal light propagation via incoherent pump field

We investigate the dispersion and the absorption properties of a weak probe field in a three-level Lambda-type atomic system. We use just an incoherent field for controlling the group velocity of light. It is shown that the slope of dispersion changes from positive to negative just with changing the intensity of the indirect incoherent pumping field. Gain-assisted superluminal light propagation appears in this system. No laser field is used in the pumping processes

Generic health literacy measurement instruments for children and adolescents:a systematic review of the literature

Background Health literacy is an important health promotion concern and recently children and adolescents have been the focus of increased academic attention. To assess the health literacy of this population, researchers have been focussing on developing instruments to measure their health literacy. Compared to the wider availability of instruments for adults, only a few tools are known for younger age groups. The objective of this study is to systematically review the field of generic child and adolescent health literacy measurement instruments that are currently available. Method A systematic literature search was undertaken in five databases (PubMed, CINAHL, PsycNET, ERIC, and FIS) on articles published between January 1990 and July 2015, addressing children and adolescents ?18 years old. Eligible articles were analysed, data was extracted, and synthesised according to review objectives. Results Fifteen generic health literacy measurement instruments for children and adolescents were identified. All, except two, are self-administered instruments. Seven are objective measures (performance-based tests), seven are subjective measures (self-reporting), and one uses a mixed-method measurement. Most instruments applied a broad and multidimensional understanding of health literacy. The instruments were developed in eight different countries, with most tools originating in the United States (n =?6). Among the instruments, 31 different components related to health literacy were identified. Accordingly, the studies exhibit a variety of implicit or explicit conceptual and operational definitions, and most instruments have been used in schools and other educational contexts. While the youngest age group studied was 7-year-old children within a parent-child study, there is only one instrument specifically designed for primary school children and none for early years. Conclusions Despite the reported paucity of health literacy research involving children and adolescents, an unexpected number of health literacy measurement studies in children?s populations was found. Most instruments tend to measure their own specific understanding of health literacy and not all provide sufficient conceptual information. To advance health literacy instruments, a much more standardised approach is necessary including improved reporting on the development and validation processes. Further research is required to improve health literacy instruments for children and adolescents and to provide knowledge to inform effective interventionspublishersversionPeer reviewe

Safety climate factors in construction – a literature review

It is an established fact that a mature safety climate and a rich safety culture contribute to achieving a safe workplace. This paper aims to explore and to make explicit the existing safety climate assessment tools and dimensions and suggests the leading factors that can be used for safety climate assessment in construction. The construction industry and the status of occupational safety and health are firstly discussed in a global context. The concept of safety climate is then discussed with a review of different safety climate factors from the published literature. A qualitative research method was employed to explore the existing safety climate factors. A total of 19 safety climate assessment tools with 103 safety climate factors spanning over a period of 39 years (1980–2019) are discussed. The most prevailing safety climate factors including management commitment, training, employees’ involvement, behaviour, communication, accountability and justice, and leadership are discussed in the paper. It is recommended that the factors discussed in this paper may need to be validated first before they are incorporated in the assessment of the safety climate of a specific construction project and organisation in a country or region

Gesundheitsförderung durch Elternbildung in „Settings“: Strategien zur Erreichbarkeit sozial benachteiliger Mütter und Väter

Hintergrund Je niedriger der soziale Status von Müttern und Vätern, desto höher ist die Verbreitung von Gesundheitsstörungen und Krankheiten bei ihnen selbst und auch bei ihren Kindern. Für Strategien der Gesundheitsförderung ist es entsprechend wichtig, Eltern mit niedrigem Sozialstatus stärker als bisher einzubeziehen. Ziel Da Eltern mit den bisherigen freien Angeboten nur sehr schwer erreicht werden können, wird in diesem Beitrag analysiert, auf welchen Wegen Elternbildungsprogramme über die Settings Kindergarten, Schule und Jugend- und Familienhilfe in die Lebenswelt aller Familien verbindlich eingebunden werden können. Ergebnis Am Beispiel von drei unterschiedlichen Elternbildungsprogrammen („Lions-Quest“, „STEP“ und „U-Boot“) wird im Rahmen einer formativen Evaluation analysiert, auf welche Weise diese Einbindung gelingen kann. Am Beispiel des STEP-Elterntrainings wird nachgewiesen, dass durch ein in die Settings eingebettetes Angebot mehr Mütter und Väter aus sozial benachteiligten Familien erreicht werden können als mit einem nicht institutionell verankerten Angebot
