ABSTRACTThis paper presents a small-scale qualitative study, which addressed stories of ‘becoming an undergraduate student’. The work took place in one university in the South West of England and involved 4 researchers, 4 co-researchers (undergraduate students) and 12 students from a Faculty of Arts and Humanities. Stories of ‘becoming student’ were perceived and experienced by the researchers as containing complex histories, intertwined with problematic systemic processes, which combined to create challenging, political and diverse realities for students. There was a consensus amongst the researchers that institutional practices did not work to uncover these lived experiences, nor aim to understand them. The study aimed to gain further insight into what becoming a student entails, how ‘student’ is positioned by the academy and to consider how future practices could make transitions into the student world more visible, shared and understood. The work highlights how processes and experiences of becoming an undergraduate student are wide, varied and complex but there are common matters of concern; issues of resources, the importance of student networks and the impact of external perceptions. The authors suggest that if these aspects of the student world were made more visible and understood, Higher Education (H.E) may be better prepared to support positive student transition, success and overall experience. 相似文献

Altitude exposure and exercise elicit oxidative stress in blood; however, exercise recovery at 5000 m attenuates oxidative stress. The purpose was to determine the altitude threshold at which blood oxidative stress is blunted during exercise recovery. Twelve males 18–28 years performed four-cycle ergometry bouts (60 min, 70% VO2max, at 975 m). In a randomised counterbalanced crossover design, participants recovered 6 h at 0, 1667, 3333 and 5000 m in a normobaric hypoxia chamber (recovery altitudes were simulated by using a computerised system in an environmental chamber by lowering the partial pressure of oxygen to match that of the respective altitude). Oxygen saturation was monitored throughout exercise recovery. Blood samples obtained pre-, post-, 1 h post- and 5 h post-exercise were assayed for ferric-reducing antioxidant plasma, Trolox equivalent antioxidant capacity, uric acid, lipid hydroperoxides and protein carbonyls. Muscle biopsies obtained pre and 6 h were analysed by real-time polymerase chain reaction to quantify expression of hemeoxgenase 1, superoxide dismutase 2 and nuclear factor (euthyroid-derived 2)-like factor. Pulse oximetry data were similar during exercise, but decreased for the three highest recovery elevations (0 m = 0%, 1667 m = ?3%; 3333 m = ?7%; 5000 m = ?17%). A time-dependent oxidative stress occurred following exercise for all variables, but the two highest recovery altitudes partially attenuated the lipid hydroperoxide response (0 m = +135%, 1667 m = +251%, 3333 m = +99%; 5000 m = +108%). Data may indicate an altitude threshold between 1667 and 3333 m, above which the oxidative stress response is blunted during exercise recovery. 相似文献

Although comprehensive and ecological approaches to early childhood prevention are commonly advocated, there are few examples of long-term follow-up of such programs. In this monograph, we investigate the medium- and long-term effects of an ecological, community-based prevention project for primary school children and families living in three economically disadvantaged neighborhoods in Ontario, Canada. The Better Beginnings, Better Futures (BBBF) project is one of the most ambitious Canadian research projects on the long-term impacts of early childhood prevention programming to date. Bronfenbrenner's ecological model of human development informed program planning, implementation, and evaluation. Using a quasi-experimental design, the BBBF longitudinal research study involved 601 children and their families who participated in BBBF programs when children were between 4 and 8 years old and 358 children and their families from sociodemographically matched comparison communities. We collected extensive child, parent, family, and community outcome data when children were in Grade 3 (age 8–9), Grade 6 (age 11–12), and Grade 9 (age 14–15). The BBBF mandate was to develop programs that would positively impact all areas of child's development; our findings reflect this ecological approach. We found marked positive effects in social and school functioning domains in Grades 6 and 9 and evidence of fewer emotional and behavioral problems in school across the three grades. Parents from BBBF sites reported greater feelings of social support and more positive ratings of marital satisfaction and general family functioning, especially at the Grade 9 follow-up. Positive neighborhood-level effects were also evident. Economic analyses at Grade 9 showed BBBF participation was associated with government savings of $912 per child. These findings provide evidence that an affordable, ecological, community-based prevention program can promote long-term development of children living in disadvantaged neighborhoods and produce monetary benefits to government as soon as 7 years after program completion. 相似文献

ABSTRACTUniversities are now compelled to attend to metrics that (re)shape our conceptualisation of the student experience. New technologies such as learning analytics (LA) promise the ability to target personalised support to profiled ‘at risk’ students through mapping large-scale historic student engagement data such as attendance, library use, and virtual learning environment activity as well as demographic information and typical student outcomes. Yet serious ethical and implementation issues remain. Data-driven labelling of students as ‘high risk’, ‘hard to reach’ or ‘vulnerable’ creates conflict between promoting personal growth and human flourishing and treating people merely as data points. This article argues that universities must resist the assumption that numbers and algorithms alone can solve the ‘problem’ of student retention and performance; rather, LA work must be underpinned by a reconnection with the agreed values relating to the purpose of higher education, including democratic engagement, recognition of diverse and individual experience, and processes of becoming. Such a reconnection, this article contends, is possible when LA work is designed and implemented in genuine collaboration and partnership with students. 相似文献

ABSTRACTBecoming a university graduate has long been considered the route to individual occupational and social mobility, while educating more citizens has been assumed to add to a nation’s human capital and competitiveness. University education has come to be associated with individual and societal aspiration. However, changes in the labour market associated with globalisation, technology, and fears of graduate underemployment have served to question this. This paper seeks to uncover the meaning that individuals construct about their early careers as they navigate such uncertain contexts. It reports on a study based on the graduate population of one university in England. Analysis tests the value of Figured Worlds theory. Using the construct of ‘self-authoring’, this paper identifies competing voices around employability and career success. Findings reveal how graduates orchestrate varied voices, in order to find ways to figure their experience and what it means to be a successful graduate. 相似文献

Perceived Internet health literacy of HIV-positive people through the provision of a computer and Internet health education intervention 总被引:1,自引:0,他引:1
Objective: The objective of this study was to assess perceived Internet health literacy of HIV‐positive people before and after an Internet health information educational intervention. Methods: We developed a 50‐min educational intervention on basic computer skills and online health information evaluation. We administered a demographic survey and a validated health literacy survey (eHEALS) at baseline, immediately after, and 3 months the class. Changes in scores between the surveys were analysed. Results: Eighteen HIV‐positive participants were included in the final analysis. Before the intervention, most respondents’ assessment of their ability to access Internet health information was unfavourable. Post‐intervention, the majority of respondents agreed or strongly agreed they were able to access and identify Internet health information resources. The increase in self‐assessed skill level was statistically significant for all eight items eHEALS (P < 0.05). Scores for the 3‐month follow‐up survey remained higher than pre‐intervention scores for most items. Conclusions: Providing an interdisciplinary brief introductory Internet health information educational intervention HIV‐positive people with baseline low perceived Internet health literacy significantly improves confidence in finding and using Internet health information resources. Studies with larger numbers of participants should be undertaken to determine if brief interventions improve self‐care, patient outcomes and use of emergency services. 相似文献

AbstractThis paper argues that the bias in Western philosophy is tied to its humanist ideology that pictures itself as central to the natural history of humanity and is historically linked to the emergence of humanism as pedagogy. 相似文献
