Some Student Conceptions of Electromagnetic Induction

Introductory electromagnetism is a central part of undergraduate physics. Although there has been some research into student conceptions of electromagnetism, studies have been sparse and separated. This study sought to explore second year physics students’ conceptions of electromagnetism, to investigate to what extent the results from the present study are similar to these results from other studies, and to uncover any new forms of alternative conceptions. Data for this study came from 15 in-depth interviews. Three previously unreported alternative conceptions were identified in the study: 1) induced current varies proportionately with current in solenoid; 2) there must be contact between magnetic flux and the external coil in order for any emf to be induced in the coil; 3) coulombic or electrostatic potential difference is present in an induced electric field. These alternative conceptions were manifested in these students’ explanations of electromagnetic phenomena presented to them during the interviews.

Work Values of University Students in Chinese Mainland, Taiwan, and Hong Kong

Leuty and Hansen (Journal of Vocational Behavior 79:379–390, 2011) identified six domains of work values in undergraduate students in the West. The review undertaken in this paper suggests that the factor structure of work values of university students in Mainland China, Taiwan and Hong Kong essentially matches these six domains, except for the omission of ‘Family Maintenance’ and Wang’s (Indigenous Psychological Research in Chinese Societies 2:206–250, 1993) ‘Instrumental Values.’ This suggests some commonality in the work values construct between the East and West, but there are a few subtle differences. It is argued that such differences heighten the need for measurement scales with context-specific and society-specific items when examining work values in different settings.     

The Relationships Among Isokinetic Endurance,Initial Strength Level,and Fiber Type

Abstract

Knee extension isokinetic peak torque was assessed at angular velocities of 0, 30, 180, and 240[ddot]/sec, and isokinetic endurance was assessed by 50 consecutive contractions at 180[ddot]/sec in eight college age men. Also, muscle fiber type of the vastus lateralis was determined and related to isokinetic strength and fatigability. To determine the influence of initial strength on isokinetic endurance the 50 serial isokinetic contractions were assessed after subjects performed two bicycle exercise regimens designed to affect initial strength levels. Neither isokinetic peak torques (made relative to MVC or per Kg of body weight) nor the amount of strength loss over the 50 contractions correlated with fiber type. The peak torques at 180[ddot]/sec at the start of the 50 contractions differed over the three conditions (unfatigued and after the two bicycle exercise regimens), however, the amount of of strength loss over the 50 trials was similar for the three conditions. Also, the patterns of the three isokinetic fatigue curves were remarkably similar. Thus, the initial strength level across the treatments did not affect the rate of fatigue. However, when the treatment conditions were examined separately, the amount of strength loss over the 50 trials correlated significantly with initial strength. Thus, factors other than, or in addition to, fiber type and initial strength level must influence the rate of isokinetic fatigue.     

University rankings as a zoning technology: a Taiwanese perspective on an imaginary Greater China higher education region

This paper argues that global university rankings can be understood as a mechanism upholding Taiwan's interests in light of cross-national analysis of university ranking and recent discussion on regionalisation of higher education in Asia. To draw an analytical framework, it begins by delineating a conceptualisation of university ranking, in which ranking exercises are seen as a form of institutions in the globalised field of education politics and policy. In anticipation of the emergence of the Greater China higher education region, the paper suggests that global university ranking can be used as a zoning technology to form an imaginary line of cultural and academic sovereignty, and to affect university strategies and government policies. This analysis not only explains how global university rankings can be used to uphold interests of Taiwan's higher education, but also sheds light on the way to constitute subjectivity in the process of regionalisation of worldwide higher education.     

重建西方对比语言学史——洪堡特和沃尔夫对开创对比语言学的贡献

西方对比语言学者通常认为对比语言学始于上世纪50年代,本文作者经过研究,认为这一历史还可以上溯,其中19世纪20年代德国学者洪堡特、20世纪20年代欧洲学者叶斯柏森和40年代美国学者沃尔夫起了重要作用。本文集中讨论了洪堡特与沃尔夫对开创对比语言学的贡献。     

Short report Further efforts in validating a 'spurning scale' for teachers

The present study represents our continuing effort to validate a 'spurning scale' for teachers, based on a model on spurned helpers' reactions. Three approaches were used to examine the validity of the scale: the spurning scores of teachers working with more achieving students vs the scores of teachers teaching less achieving students. The relationships between the spurning scores and job satisfaction and turnover scores; and the relationships between the spurning scores and scores indicative of stress arising from interactions with one's students and supervisor. Serving teachers in Hong Kong responded to a questionnaire that contained the variables of interest. The results provided further evidence for the validity of the scale.     

Making connections: students’ reflection on aging competency approach in gerontology education

The increase of the US older adult population requires additional professionally trained staff in health and social services. Exposing knowledge and skills of gerontology to address aging competency among student in higher education can better prepare for students’ future educational and career planning. The aim of this study is to understand students’ reflections on an aging competency approach in an Introduction to Gerontology online class. Students’ reflections revealed insights including the increase of aging knowledge and skills, empathic understanding increased through a self-awareness approach, attitudes changed toward older adults, impact of experiential interviews on students’ understanding of aging. The implementation of a combined pedagogy in course construction will be discussed.
