Promoting and Providing Expert Guidance in Work-intensive Clinical Settings

This paper discusses how expert guidance can be best provided in work intensive clinical settings. The adequacy for supporting learning in the clinical practicum for health care disciplines is often complicated by the intensive work practices in healthcare settings. Often, clinicians’ work is so intense that the scope for providing close guidance for students is quite restricted. The case advanced here draws on a range of empirical work to propose how clinician-student interactions might be optimized through the provision of a clinical supervisor to assist clinicians develop collegial relationships and acquire skills in guided learning such as demonstrating and role-modeling. These roles can contribute in essential ways to the development of learning environments where clinicians have the opportunity to facilitate the learning of others as part of their workload, and without being burdened by the requirements of teaching and assessment processes. It differs from other approaches because although clinicians partner students and provide feedback to them, clinicians are not expected to formally assess or award a grade for student performance. Assessment and remedial action, when required, is undertaken by the role of a designated clinical supervisor qualified to perform such activities.     

Biosensors for immune cell analysis-A perspective

Massively parallel analysis of single immune cells or small immune cell colonies for disease detection, drug screening, and antibody production represents a "killer app" for the rapidly maturing microfabrication and microfluidic technologies. In our view, microfabricated solid-phase and flow cytometry platforms of the future will be complete with biosensors and electrical/mechanical/optical actuators and will enable multi-parametric analysis of cell function, real-time detection of secreted signals, and facile retrieval of cells deemed interesting.     

Best performances by men and women open-water swimmers during the 'English Channel Swim' from 1900 to 2010

Abstract Little research has examined ultra-endurance swimming performances. The 'English Channel Swim', where swimmers have to cover a distance of 32?km between England and France represents a unique long-distance, open-water, sea-swimming challenge, and each year swimmers from all over the world try to succeed in this challenge. The best times in minutes and the nationality of successful men and women swimmers were analysed from 1900 to 2010. A total of 1,533 swimmers (455 women and 1,078 men) from more than 40 countries have successfully completed the 'English Channel Swim'. Great Britain was the country most represented, with 38% of the total, followed by the United States with 20%. Swim speed has increased progressively for both sexes (P??0.05). The results suggest that the performance of women open-water ultra-distance swimmers may be similar to that of men. Further studies investigating anthropometrical and physiological characteristics of open-water ultra-swimmers are needed to compare men's and women's open-water ultra-swim performances.     

A Comparison of Linking Methods for Estimating National Trends in International Comparative Large‐Scale Assessments in the Presence of Cross‐National DIF

Trend estimation in international comparative large‐scale assessments relies on measurement invariance between countries. However, cross‐national differential item functioning (DIF) has been repeatedly documented. We ran a simulation study using national item parameters, which required trends to be computed separately for each country, to compare trend estimation performances to two linking methods employing international item parameters across several conditions. The trend estimates based on the national item parameters were more accurate than the trend estimates based on the international item parameters when cross‐national DIF was present. Moreover, the use of fixed common item parameter calibrations led to biased trend estimates. The detection and elimination of DIF can reduce this bias but is also likely to increase the total error.     

Students’ School Motivation and Aspiration Over High School Years

Students from a school in Hong Kong (n?=?199) responded to 22 items asking about their school motivation and aspirations in a survey. Structural equation models found four school motivation factors consistent with the task, effort, competition, and praise scales of the Inventory of School Motivation, one education aspiration factor, one career aspiration factor, and significant relations of the motivation factors with the aspiration factors. Task and effort orientations were found to be stronger than the other orientations and to have relatively stronger associations with education aspirations, whereas task and praise had stronger associations with career aspirations. In examining potential change in students’ goal orientations and aspirations through high school years, analysis of variance found that 7th‐graders had significantly higher scores in task and effort orientations and career aspirations than 9th‐graders, and higher scores in praise orientation than 11th‐graders. The apparent drop in motivation scores from Grade 7, especially in task and effort orientations, both pertaining to a mastery orientation dimension that has been assumed to be a major driving force for excellence, calls for urgent attention to student motivation in junior high school classes.

Creatine Kinase Activity Weakly Correlates to Volume Completed Following Upper Body Resistance Exercise

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4,156 kg, SD = 867, for 3 min; vs. M = 3,503 kg, SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r =.45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.
