This paper explores the association between moderate levels of physical activity (PA) and health benefits in well being and symptoms such as tiredness, back pain, and constipation. Participants in the Australian Longitudinal Study on Women's Health, 14,502 young women (ages 18-23 years), 13,609 middle-age women (45-50 years), and 11,421 older women (ages 70-75 years), answered questions about vigorous and less vigorous exercise (used to determine a physical activity score), well being (SF-36), symptoms, and medical conditions. There were significant associations between the PA score and SF-36 in each cohort. Odds ratios (OR) for a range of symptoms and conditions were lower for women who reported low to moderate activity than for sedentary women, for example, for young women or for constipation = 0.76 (CI, 0.65-0.89), for middle-age women or for tiredness = 0.70 (0.63-0.78). There was no threshold of PA at which health benefits increased significantly. Although cross-sectional, the findings suggest that low-to-moderate levels of exercise are associated with a range of health benefits for women of all ages. These preliminary findings will be followed up during the longitudinal study.  相似文献   

Medical library services in Switzerland: catching up with EBM     

Gerhard Bissels  Sabine D. Klein  Isabelle de Kaenel 《Health information and libraries journal》2019,36(4):372-377

The feature is a part of the series about medical library services in various countries. It gives an overview of medical library services to support research, education and clinical practice in Switzerland. Data were collected by means of an online survey and set in the wider context of the Swiss healthcare system. Key findings are that library services, including support by academic librarians, are provided to health care staff in hospitals – both university and others, while there is no information service infrastructure to serve the large number of GPs and specialists who mostly run their own practice. The authors recommend that – if the health authorities take EBM seriously – information services should be introduced for these small practices. J.M.  相似文献

STEM Is Elementary: Challenges Faced by Elementary Teachers in the Era of the Next Generation Science Standards     

Aaron D. Isabelle 《The Educational forum》2017,81(1):83-91

For students to achieve the goals of the Next Generation Science Standards (NGSS) by Grade 12, thinking and acting like scientists and engineers must begin in the elementary grades. However, elementary teachers may find this challenging -because language arts and mathematics still dominate many classrooms—often at the expense of science. This essay examines the science skills elementary students are expected to learn and how teachers and administrators can approach the increased demands of NGSS.  相似文献   

Joint trajectories of behavioral,affective, and cognitive engagement in elementary school     

Isabelle Archambault  Véronique Dupéré 《The Journal of educational research》2017,110(2):188-198

The aim of the present study was to model student trajectories of behavioral, affective, and cognitive engagement from Grade 3 to Grade 6. The authors also examined whether teachers perceptions could predict student trajectory membership. The authors collected data from a sample of 831 students and 152 teachers. Using multiple-process growth mixture modeling, they identified 5 distinct trajectories of student engagement. Although a large majority of children presented a stable and high level of engagement on the three dimensions over time, more than one third of them showed a lower or changing level of engagement as the years progressed. These students were more likely to be boys and to be perceived by teachers as being less engaged. They also present more learning or behavioral problems and share less positive relationships with teachers. The results support the need to consider group-based differences when designing and adapting prevention and intervention strategies to favor student engagement.  相似文献

Public libraries embrace citizen science: Strengths and challenges     

Anna Cigarini  Isabelle Bonhoure  Julián Vicens  Josep Perelló 《Library & information science research》2021,43(2):101090

Can public libraries become hubs for citizen science? In line with the principles of citizen science, this question was answered collaboratively with librarians from the Barcelona Network of Public Libraries who performed two hands-on activities. One activity was a training course taken by 30 librarians from 24 different libraries which enabled them to envisage citizen science implementation at each library. The other activity consisted of co-creating a citizen social science project and involved 40 library users, seven librarians from three different cities, and professional scientists. The analysis considers the perspectives of both librarians and users, through participant observation, surveys, and a focus group to identify strengths and challenges. The overall results suggest that public libraries can offer leadership in the promotion of citizen science and contribute to the mission of public libraries to act as local community hubs. The main challenges identified were related to the complexity of collaboration, uncertainty regarding research co-creation, and participant retention strategies.  相似文献   

Conservation of stained glass windows with protective glazing: Main results from the European VIDRIO research programme     

Adriana Bernardi  Francesca Becherini  Marco Verità  Patrick Ausset  Maura Bellio  Ulrike Brinkmann  Helene Cachier  Anne Chabas  Felix Deutsch  Marie-Pierre Etcheverry  Franco Geotti Bianchini  Ricardo H.M.

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.  相似文献

Teachers’ motives for learning in networks: costs,rewards and community interest     

Antoine van den Beemt  Evelien Ketelaar  Isabelle Diepstraten  Maarten de Laat 《Educational research; a review for teachers and all concerned with progress in education》2018,60(1):31-46

Background: This paper discusses teachers’ perspectives on learning networks and their motives for participating in these networks. Although it is widely held that teachers’ learning may be developed through learning networks, not all teachers participate in such networks.

Purpose: The theme of reciprocity, central to studies in the area of learning in networks, is often approached from a rational exchange perspective. This study attempts to extend this approach with reference to the concept of symbolic interactionism. The study was guided by the following research question: What is the relationship between teachers’ perceptions of learning networks and their motives for participation or non-participation in these networks?

Design and methods: In order to address this research question, semi-structured interviews among 25 teachers in secondary education in the Netherlands were carried out. The semi-structured interviews consisted of three parts: background information, perspectives on learning networks and personal experiences with those networks. Data were analysed qualitatively and analyses consisted of within-case analysis, and cross-case analysis of interview fragments. Three themes were considered: (1) perspectives on learning networks, (2) motives for participation perceived as rational exchange, (3) motives for participation perceived as related to social order.

Findings: The findings are presented around these three themes. Each theme is discussed in relation to relevant aspects from the literature. Findings indicated that teachers perceived learning networks to be organised both within-school and outside school, and mostly focused around specific content knowledge. Reasons for participation or non-participation were related to rational costs and rewards (such as time, technology, self-efficacy); in symbolic motives (such as joy, sharing and mutual understanding), and also in a sense of meaning that resulted from networking activities.

Conclusions: We conclude that, in addition to social exchange motives, the data suggest that symbolic aspects of communication and interaction play an important role in considerations for participation in learning networks. This may be described in terms of four ‘types’ of networking teachers: the Community focused networking teacher, the Locally focused networking teacher, the Not-yet-networking teacher, and the Non-networking teacher. It is hoped that these exploratory findings could be helpful in supporting the development of learning networks for all teachers.  相似文献
