Exploring Relationships of Sleep Duration with Eating and Physical Activity Behaviors among Canadian University Students.

BACKGROUND: Students pursuing postsecondary education are a population described as vulnerable for sleep problems, poor dietary habits, weight gain, and reduced physical activity. The primary goal of this study was to examine relationships of sleep behaviors with eating and physical activity behaviors in a sample of undergraduate health sciences students. METHODS: Using a cross-sectional design, undergraduate health sciences students in a small Canadian university were recruited to complete an on-line questionnaire about their sleep, eating, and physical activity behaviors using valid and reliable instruments. Key sociodemographic characteristics and self-reported height and weight data were also captured. RESULTS: The participants (n = 245) were on average 23 years of age, female (86%), and the majority were full-time students (92%). The mean BMI was within a healthy range (mean 24.58 SD 5.55) with the majority reporting low physical activity levels (65%). Despite self-reports of very or fairly good (65%) sleep quality in the past month, the mean global sleep scores (scores > 5, mean 7.4, SD 3.3) indicated poor overall sleep quality. Poorer sleep quality was associated with higher BMIs (r = 0.265, p < 0.001). CONCLUSIONS: The findings highlight the need to expand the scope of on-campus wellness programs to promote healthy sleep habits in a vulnerable university population.

Using wikis to stimulate collaborative learning in two online health sciences courses.

BACKGROUND: The use of wiki technology fits well in courses that encourage constructive knowledge building and social learning by a community of learners. Pedagogically, wikis have attracted interest in higher education environments because they facilitate the collaborative processes required for developing student group assignments. METHOD: This article describes a pilot project to assess the implementation of wikis in two online small- and mid-sized elective courses comprising nursing students in third- or fourth-year undergraduate levels within interdisciplinary health sciences courses. RESULTS: The need exists to further develop the pedagogical use of wiki environments before they can be expected to support collaboration among undergraduate nursing students. CONCLUSION: Adapting wiki implementation to suitable well-matched courses will make adaptation of wikis into nursing curricula more effective and may increase the chances that nursing students will hone the collaborative abilities that are essential in their future professional roles in communities of practice.

Doing 'technological time' in a pediatric hemodialysis unit: an ethnography of children.

Since the 1960s, hemodialysis has been a common intervention for children with end-stage renal disease, however little is known about how they experience hospital-based hemodialysis. A focused ethnography was undertaken to explore children׳s perspectives of the time, space and technology of a hemodialysis unit at a Canadian pediatric urban hospital. The children׳s temporal and socio-spatial positions were an effect of their technologically mediated embodiment and shaped their perspectives, evaluations and expectations. The findings suggest that further explorations are needed to envision ways to create with children an overall positive place that merges and balances technological care with child focused care.

'Futureless persons': shifting life expectancies and the vicissitudes of progressive illness.

Medical technological advances can have profound effects on people's lives by extending the life course and creating uncertain futures. This is the case for a number of persons with 'diseases of childhood' who can now survive well into adulthood with technological support. This paper draws on a Canadian qualitative study of young men with Duchenne muscular dystrophy (DMD)which examined the effects of a shifting life expectancy on personal identities. Engaging with Pierre Bourdieu's central concept of habitus, we discuss the temporal dimensions of social exclusion and marginalised identities. Participants' narrative accounts revealed how their dispositions were orientated to a shortened lifespan that exerted damaging effects regardless of actual lifespan. Compounding their material, social and symbolic isolation was a temporal isolation whereby the men had lived every day anticipating that it could be their last for as much as a decade. The findings suggest a need to re-orient medical and social discourses to serve and include adults with DMD and other conditions previously limited to childhood in their communities.

Concerning technology: thinking with Heidegger.

In human lives, technology holds sway in mundane and extraordinary ways, such as in the ways we work, entertain, transport, and feed ourselves, and importantly in the ways we encounter and manage health, disease, illness, and death. A significant area of Heidegger's later work is questioning technology. Unlike many current inquiries that centre on contemporary technology's function, utility, and positive transformations, Heidegger offers a radical way of thinking about technology through developing an inquiry that uncovers technology's essence of revealing. In this article, Heidegger's thinking about technological modes of revealing in regard to bodies, health, and illness is explored. In Heidegger's view, the ordered revealing of modern technology has overshadowed other modes of revealing. This article highlights how remembering concealment and unconcealment in its many modes can be relevant to nurses and others involved in health care. Through tracing Heidegger's thinking about technology, a more critical approach to the effects and outcomes of modern technologies within health care systems can be generated.
