PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.  相似文献   

The effects of exercise in hypoxic and normoxic conditions on endothelin-1 and arterial compliance

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males.  相似文献

DNA microarray wet lab simulation brings genomics into the high school curriculum   总被引：1，自引：1，他引：0

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献   

Positive emotions: passionate scholarship and student transformation     

Colin Beard  Barbara Humberstone  Ben Clayton 《Teaching in Higher Education》2013,18(6):630-643

This paper challenges the practical and conceptual understanding of the role of emotions in higher education from the twin perspectives of transition and transformation. Focusing on the neglected area of positive emotions, exploratory data reveal a rich, low-level milieu of undergraduate emotional awareness in students chiefly attributed to pedagogic actions, primarily extrinsically orientated, and pervasive throughout the learning experience. The data conceive positive affect as oppositional, principally ephemeral and linked to performative pedagogic endeavours of getting, knowing and doing. A cyclical social dynamic of reciprocity, generating positive feedback loops, is highlighted. Finally we inductively construct a tentative ‘emotion-transition framework’ to assist our understanding of positive emotion as a force for transformational change; our contention is that higher education might proactively craft pedagogic spaces so as to unite the feeling discourse, the thinking discourse (epistemological self) and the wider life-self (ontological) discourse.  相似文献   

National and international disability rights legislation: a qualitative account of its enactment in Australia     

Ben Whitburn 《International Journal of Inclusive Education》2013,17(5):518-529

In this paper, a detailed analysis based on the lived experiences of the study participants and the researcher (each with vision impairment) in education, post school and in the pursuit for employment is developed. The policy discourses of disability legislation – both at national and international levels – are explored with particular reference to their enactment in Australia. The analysis focuses on the collective indifference to detached others, which is evident in the linguistic construction of people with disabilities in the United Nations [(2006). Convention of the Rights of Persons with Disabilities. New York: United Nations] and the Australian Standards for Education 2005 [Australian Department of Education, Science and Training. 2006. Disability Standards for Education 2005 Plus Guidance Notes. Accessed March 12, 2012. http://nla.gov.au/nla.arc-7692.]. Together, these elements reflect the neoliberal principles that cast a shadow over the discourses of the disability policies.  相似文献   

Community‐based early intervention for children with behavioural,emotional and social problems: evaluation of the Scallywags Scheme     

Kathryn Lovering  Ian Frampton  Ben Crowe  Alice Moseley  Moira Broadhead 《Emotional and Behavioural Difficulties》2013,18(2):83-104

Scallywags is a community‐based, early intervention programme for young children (aged 3–7) with behavioural, emotional and social problems, which integrates work in the home and school with a parenting curriculum and direct work with children. A pre‐post intervention study across multi‐sites of 340 participants is reported. Using standardised measures, the study found statistically significant reductions in problems at home and school experienced by children who completed the programme, and in parental stress levels. Participation was found to be high and the project acceptable to parents, many of whom would be described as hard to reach. The rigorous evaluation of this real‐life service and its positive outcomes highlight the potential of such programmes to tackle the needs of these children and families, and help prevent longer‐term problems associated with early onset behavioural problems, including social exclusion, antisocial behaviour and educational failure.  相似文献

SURVEY OF JEWISH EDUCATION IN NEW YORK CITY     

Ben Rosen 《Journal of Jewish Education》2013,79(2):82-96

This case study examines the contours of culturally relevant pedagogy in an undergraduate preservice teacher education program for Jewish women. The case describes how the assigned reading of Albarelli’s (2000) narrative of teaching in a Hasidic Jewish school, Teacha! Stories from a Yeshiva, disrupts the classroom community, diminishes student engagement with the course, and undermines student confidence in the instructor. This research explores what happens when “respect for” challenges “reflection about.” The study finds that differential cultural understandings surrounding the concept of “respect” mediate the discourse. The author raises questions about the ethics of social justice in religious teacher education, probes the poverty of educational reform in a landscape of nondiscussables, and offers strategies for navigating this tender terrain.  相似文献
