Educational Programs for the Promotion of Health at School: A Systematic Review.
2021
Context: Health promotion programs generate healthy changes in the educational community. However, not all of them meet the expected objectives due to multiple factors that affect their development, such as the teachers overload work, the lack of specific training, the lack of time to carry out health promotion activities, the lack of flexibility of the programs, and their non-inclusion in the training programs of the centers. Objective: To know the scope of the strategies and programs that promote healthy habits among students in compulsory educational stages. Data sources: a systematic review of articles in English, using the Web of Science (WOS), Medline, and PsycINFO databases. Sin fina…
In search of a theoretical framework of factors influencing work and life balance
2021
Work and life balance (WLB) has gained noticeable attention amid the pandemic. Even before the outbreak of COVID-19, the increasing pace of life encouraged the investigation of individual and organisational aspects of WLB. Physically and mentally healthy people help society develop and grow. Health issues caused by work and life imbalance lead to dissatisfaction with both work and life, which, in turn, leads to higher stress and stress-related illnesses, for instance, burnout. From the organisational point of view, WLB is a factor in analysing the efficiency of an enterprise. The consequences of a work-life imbalance are intentional or unintentional absence, high employee turnover, low prod…
Managing in-country transportation risks in humanitarian supply chains by logistics service providers: Insights from the 2015 Nepal earthquake
2017
International audience; Humanitarian supply chains (HSCs) play a central role in effective and efficient disaster relief operations. Transportation has a critical share in HSCs and managing its risks helps to avoid further disruptions in relief operations. However, there is no common approach to or culture of risk management that its applicability has been studied through recent cases. This paper incorporates an empirical research design and makes a threefold contribution: first, it identifies in-country transportation risks during Nepal response. Second, we evaluate afore identified risks through an expert driven risk assessment grid. Third, we use our field data to study how some humanita…
User evaluation of a therapist-guided internet-delivered treatment program for anxiety disorders: A qualitative study
2021
Therapist-guided internet-based cognitive behaviour therapy (ICBT) has been proposed as a potential means to increase individuals' access to quality mental health care and effective treatment. Guided ICBT aims to increase a patient's knowledge and competence to better cope with their disorder. Despite the growing evidence supporting the effects of guided ICBT, there is remarkably little research on the different factors that are important for patients to achieve effects from using such digital treatment interventions. Thus, the aim of this study was to conduct a user evaluation of a therapist-guided ICBT program using the updated DeLone and McLean (D&M) model for measuring information syste…
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
Flexible spikes The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein enables viral entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor and is a major target for neutralizing antibodies. About 20 to 40 spikes decorate the surface of virions. Turoňová et al. now show that the spike is flexibly connected to the viral surface by three hinges that are well protected by glycosylation sites. The flexibility imparted by these hinges may explain how multiple spikes act in concert to engage onto the flat surface of a host cell. Science, this issue p. 203
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
AbstractThe spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is required for cell entry and is the major focus for vaccine development. We combine cryo electron tomography, subtomogram averaging and molecular dynamics simulations to structurally analyze Sin situ. Compared to recombinant S, the viral S is more heavily glycosylated and occurs predominantly in a closed pre-fusion conformation. We show that the stalk domain of S contains three hinges that give the globular domain unexpected orientational freedom. We propose that the hinges allow S to scan the host cell surface, shielded from antibodies by an extensive glycan coat. The structure of native S contr…
Massive Open Online Courses for IFRS Education: A Point of view of Spanish Accounting Educators
2016
Abstract This paper is based on a survey of 103 accounting educators from different universities of Spain on the use of MOOC, especially as regards teaching IFRS. The results show significant differences in three areas of opinion: i) the importance of the use of Internet and some Web tools for academic use; ii) general knowledge and perception of MOOCs; and iii) the opinions regarding the interest of MOOCs on IFRS. The overall opinion of educators is positive because, although the majority has never taught or participated in a MOOC, over 80% consider it useful in the learning process. Flexibility is considered the main advantage of MOOCs as well as its valuable potential for autonomous lear…
Intervening in domestic violence : interprofessional collaboration among social and health care professionals and the police
2021
Encountering domestic violence victims, perpetrators and witnesses in the multiprofessional fields of health and social care and policing includes various challenges. Each professional group perceives domestic violence from its own perspective, linked to its position in the field, core tasks, institutional practices and organizational structures. In this study, we examine interprofessional collaboration among Finnish social and health care professionals and police officers, focusing on the practices and conceptions concerning domestic violence interventions. The data consists of 16 focus group interviews, involving a total of 67 interviewees from social and health care professions and the p…
Development of a modular room-temperature hydride storage system for vehicular applications
2016
The subject of this paper concerns the development of a vehicular hydrogen tank system, using a commercial interstitial metal hydride as storage material. The design of the tank was intended to feed a fuel cell in a light prototype vehicle, and the chosen hydride material, Hydralloy C5 by GfE, was expected to be able to absorb and desorb hydrogen in a range of pressure suitable for this purpose. A systematic analysis of the material in laboratory scale allows an extrapolation of the thermodynamic and reaction kinetics data. The following development of the modular tank was done according to the requirements of the prototype vehicle propulsion system and led to promising intermediate results…
Self-assembly of Organic Molecules on Insulating Surfaces
2015
Molecular self-assembly is known to provide a powerful tool for creating functional structures, with the ultimate structure and functionality encoded in the molecular building blocks. Upon molecule deposition onto surfaces, functional structures have been created ranging from defect-free, highly symmetric two-dimensional layers to complex assemblies with dedicated functionality. Especially organic molecules play a key role for molecular self-assembly due to their impressive structural flexibility and the high degree of control by chemical synthesis. Furthermore, the surface itself provides another exciting dimension: adjusting the subtle balance between intermolecular and molecule-surface i…
