We investigate parallel Lagrangian foliations on Kähler manifolds. On the one hand, we show that a Kähler metric admitting a parallel Lagrangian foliation must be flat. On the other hand, we give many examples of parallel Lagrangian foliations on closed flat Kähler manifolds which are not tori. These examples arise from Anosov automorphisms preserving a Kähler form.
This paper discusses the evidence for periodic human activity in the Cairngorm Mountains of Scotland from the late 9th millennium to the early 4th millennium cal bc. While contemporary paradigms for Mesolithic Europe acknowledge the significance of upland environments, the archaeological record for these areas is not yet as robust as that for the lowland zone. Results of excavation at Chest of Dee, along the headwaters of the River Dee, are set into a wider context with previously published excavations in the area. A variety of site types evidences a sophisticated relationship between people and a dynamic landscape through a period of changing climate. Archaeological benefits of the project include the ability to examine novel aspects of the archaeology leading to a more comprehensive understanding of Mesolithic lifeways. It also offers important lessons in site survival, archaeological investigation, and the management of the upland zone.
The Handbook of Behavior Change is the first wide-ranging compendium of theory- and evidence-based research and practice on behavior change. It provides scientists, students, and practitioners with the current evidence on behavior change and expert advice on how to develop, evaluate, and implement behavior change interventions. The handbook also sets an agenda for future research on behavior change theory and practice across multiple behaviors, contexts, and populations. This chapter outlines emerging issues and future research directions arising from the handbook. The chapter stresses the importance of theory development, including the need for greater emphasis on ecological and social theories; clearer descriptions and operationalizations of behavior change theories; and increased application of interdisciplinary approaches. Future research on intervention development should conduct more comprehensive intervention fidelity assessments; adopt novel means to improve the translation, feasibility, and optimization of interventions; ensure consideration of ethical issues in behavior change research; routinely evaluate mechanisms of action in behavior change interventions; and apply complex systems approaches to behavior change. “Best-practice” guidance on behavior change should consider emerging methods and approaches to behavior change; implement trials to evaluate the long-term maintenance of behavior change; and develop core curricula on behavior change to educate the next generation of scientists and practitioners.
Social problems in many domains, including health, education, social relationships, and the workplace, have their origins in human behavior. The documented links between behavior and social problems have sparked interest in governments and organizations to develop effective interventions to promote behavior change. The Handbook of Behavior Change provides comprehensive coverage of contemporary theory, research, and practice on behavior change. The handbook incorporates theory- and evidence-based approaches to behavior change with chapters from leading theorists, researchers, and practitioners from multiple disciplines, including psychology, sociology, behavioral science, economics, and implementation science. Chapters are organized into three parts: (1) Theory and Behavior Change; (2) Methods and Processes of Behavior Change: Intervention Development, Application, and Translation; and (3) Behavior Change Interventions: Practical Guides to Behavior Change. This chapter provides an overview of the theory- and evidence-based approaches of the handbook, introduces the content of the handbook, and provides suggestions on how the handbook may be used by different readers. The handbook aims to provide all interested in behavior change, including researchers and students, practitioners, and policy makers, with up-to-date knowledge on behavior change and guidance on how to develop effective interventions to change behavior in different populations and contexts.
Social problems in many domains, including health, education, social relationships, and the workplace, have their origins in human behavior. The documented links between behavior and social problems have compelled governments and organizations to prioritize and mobilize efforts to develop effective, evidence-based means to promote adaptive behavior change. In recognition of this impetus, The Handbook of Behavior Change provides comprehensive coverage of contemporary theory, research, and practice on behavior change. It summarizes current evidence-based approaches to behavior change in chapters authored by leading theorists, researchers, and practitioners from multiple disciplines, including psychology, sociology, behavioral science, economics, philosophy, and implementation science. It is the go-to resource for researchers, students, practitioners, and policy makers looking for current knowledge on behavior change and guidance on how to develop effective interventions to change behavior.
Infectious diseases professional societies, public health agencies, and healthcare regulatory agencies call for antibiotic stewardship programs (ASP) in many healthcare settings. However, medical legal implications of these programs remain largely uncharted territory. Although there is no legal precedent addressing issues of liability and standards of care on this subject, anticipating how the courts may assess questions of medical liability with respect to the various components of ASPs is important to define best practices in ASP operations, not only to manage the potential risk but also to improve patient care. This article seeks to address some of the common processes and interventions involved in antibiotic stewardship and the potential professional liability implications of these activities.
The researches show a rapid growth of mental disorders among adolescents and young adults that often cooccurs with risk behaviours, such as suicide, which is one of the leading cause of death among young ages 15-34. Therefore it's necessary to use some tools that can promote mental health getting to young lives such as Internet and media.
SUPREME (Suicide Prevention by Internet and Media Based Mental Health Promotion) is aimed to increasing the prevention of risk behaviours and mental health promotion through the use of mass media and Internet.
The main expected outcome is to improve mental health among European adolescents.
In each European countries a sample of 300 students (average age of 15 years) will be selected. The prevention program will be a highly interactive website that which will address topics such as raising awareness about mental health and suicide, combating stigma, and stimulate peer help. The program will use different means of referral to the intervention website: “Adolescent related” and “Professional related”. A questionnaire will be administered to the pupils for require the data on lifestyles, values and attitudes, psychological well-being, familiar relationship and friendship.
Some web-sites, managed by mental health professionals, produced encouraging results about their use in prevention of risk behaviours and in increase well-being, especially in youth with low self-esteem and low life-satisfaction. With the implementation of the SUPREME project we will be able to identify best practices for promoting mental health through the Internet and the media.
Suicide is one of the leading causes of death worldwide, and the third leading cause of death among people aged below 25. Mental health promotion is a central aspect of the battle against suicide and mental ill-health. The internet and the media are effective tools for disseminating information and education to adolescents and improving their mental health and well-being. in 2011 there were 2.1 billion Internet users world-wide. in a random sample of over 3000 American adults, it was found that 58% of the Internet users reported searching for health information for themselves (Atkinson et al. 2009).
The main objective of the SUPREME project is to develop a website aimed at mental health promotion and to investigate its efficacy. A secondary goal is to compare two different strategies for promoting the use of the website: one where peers are the main promoters and another with mental health professionals. The study is partly funded by the EACH and comprises 7 European countries: Estonia, Hungary, Italy, Spain, United Kingdom, Lithuania and Sweden.
Adolescents in this study approached in a random sample of schools, in each participating country, yielding a total of 2100 participants. The schools were randomized into control (minimal intervention), and intervention conditions (minimal intervention + website access). Pre-, post- and follow-up measures are used to test the efficacy of the intervention. Each intervention school is also randomized into peer and pro dissemination groups for comparison of recruitment efficiency. Preliminary results are presented.
A Miniature Thermal Emission Spectrometer (Mini-TES), based on a Michelson interferometer and Cassegrain telescope, was carried by the Spirit rover in Gusev crater and Opportunity rover at Meridiani Planum to determine the bulk mineralogy of surface materials. Spectra from the plains of Gusev demonstrate the ubiquity of olivine-rich basaltic rocks, with additional examples lofted into the adjacent Columbia Hills by meteoroid impacts. Hundreds of rocks observed with mini-TES in the Columbia Hills display spectral characteristics of variable alteration intensity, but likely with very little water involved. Rare exceptions include a tephra deposit cemented by Mg–Fe carbonates and nodular opaline silica rocks, likely indicative of a hot spring/geyser environment. Opportunity’s mini-TES confirmed orbital identification of crystalline hematite at Meridiani Planum and spectral characteristics indicative of a transition from a precursor goethite phase. The sedimentary bedrock that hosts the hematite has spectral features consistent with Al-rich opaline silica, Mg-, Ca-, and Fe-bearing sulfates, plagioclase feldspar, and nontronite. Rare rocks at both sites are recognizable as iron meteorites from their infrared reflective properties.
