An education that pierces what the knife cannot: A student perspective

If personalized medicine is the way of the future, and the physician's approach to each patient becomes more individualized and team‐based, so must the professors' approach to the medical student experience. Mayo Medical School has an innovative curriculum designed to respect and enhance the individual interests of its students. A former educator herself, and now a medical student, the author advocates for further creative curriculum design to enhance healthy student attitude learning in medical school. In her personal testimony to the healing power of art and story, she cautions institutions that ignore integrating humanities into their curriculum that their student physicians will build self‐protective barriers without self‐reflection. She argues students must have more avenues to express their emotions during difficult transitions and ethical dilemmas. This commentary describes extracurricular student projects during anatomy, and includes an example of student reflective writing in anatomy. The author suggests that narrative medicine as an emerging discipline would be an effective educational strategy when applied to any aspect of the medical curriculum, and should be considered by more medical schools for further progress in medical education.

The impact of curriculum change on health sciences first year students’ approaches to learning

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme. The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined. The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual factors, including assessment, and is the focus of ongoing curriculum development.

Youth enterprise: the role of gender and life stage in motivations,aspirations and measures of success

‘Enterprise’ has increasingly become part of the United Kingdom’s political grammar and efforts to develop entrepreneurial traits and activities in young people have been a key strand of this policy focus. As the 2008 economic recession saw a curtailed youth labour market, enterprise emerged as an appealing policy ‘solution’ to youth unemployment. Traditional measures of enterprise chart the numbers of new businesses and their survival rates. This article argues these measures tell us little about new business owners: who they are, their motivations, experiences or, own definitions of success. Further, and crucially, such measures ignore the structural constraints surrounding enterprise and the range of social factors that may determine the extent of ambition, and willingness or capacity to take risks. This article argues that although gender and life stage were contributing factors, the young people’s structurally disadvantaged positions emerge as the most significant feature of why the move into self-employment did not tend to increase their economic stability as promised. This provides an important insight into the real-life experiences of young people who are engaging in enterprise activities in the contemporary economic context, as well as the role of third sector organisations in overseeing the transition from education to work.     

A fluorescence based method for the quantification of surface functional groups in closed micro- and nanofluidic channels

Surface analysis is critical for the validation of microfluidic surface modifications for biology, chemistry, and physics applications. However, until now quantitative analytical methods have mostly been focused on open surfaces. Here, we present a new fluorescence imaging method to directly measure the surface coverage of functional groups inside assembled microchannels over a wide dynamic range. A key advance of our work is the elimination of self-quenching to obtain a linear signal even with a high density of functional groups. This method is applied to image the density and monitor the stability of vapor deposited silane layers in bonded silicon/glass micro- and nanochannels.     

Differences in the Intensity and Duration of Adolescents' Sports and Exercise Across Physical and Social Environments

We used data from the American Time Use Survey (years 2003–06) to analyze whether the intensity and duration of high school students' (ages 15–18 years) sports and exercise bouts differed across physical and social environments. Boys' sports and exercise bouts were more likely to reach a vigorous intensity when taking place at school and with friends/acquaintances/other people; whereas girls' sports and exercise bouts were more likely to reach a vigorous intensity when outdoors and alone. For boys and girls, bout durations were greater at school and with friends/acquaintances/other people than in other environments. Overall, environmental influences on the intensity but not duration of sports and exercise bouts appear to differ between boys and girls.     

An investigation of a novel three-dimensional activity monitor to predict free-living energy expenditure

Abstract

The aim of this study was to assess the capability of the 3dNX? accelerometer to predict energy expenditure in two separate, free-living cohorts. Twenty-three adolescents and 14 young adults took a single dose of doubly labelled water and wore a 3dNX? activity monitor during waking hours for a 10-day period while carrying out their normal routines. Multiple linear regression with backward elimination was used to establish the strength of the associations between various indices of energy expenditure, physical activity counts, and anthropometric variables. 3dNX? output accounted for 27% and 35% of the variance in the total energy expenditure of the adolescent and young adult cohort, respectively. The explained variance increased to 78%, with a standard error of estimate of 7%, when 3dNX? output was combined with body composition variables. The 3dNX? accelerometer can be used to predict free-living daily energy expenditure with a standard error of estimate of 1.65 MJ in adolescents and 1.52 MJ in young adults. The inclusion of anthropometric variables reduces the error to approximately 1 MJ. Although it remains to cross-validate these models in other populations, early indications suggest that the 3dNX? provides a useful method of predicting energy expenditure in free-living individuals.
