Preparing internationally minded business graduates: The role of international mobility programs     

Claude Marcotte  Jocelyn Desroches  Isabelle Poupart   《Int J Intercult Relat》2007,31(6):655-668

The first objective of this paper was to examine the institutional and individual determinants of business students’ participation in international mobility programs (IMPs). Retrospective reports were collected from business graduates of the University of Quebec in Montreal, Canada. Respondents reported having received very little information about IMPs from the different institutional sources. Logistic regression analysis revealed that when these institutional factors were present, the likelihood of student participation in IMPs increased significantly. The respondents’ interests in intercultural contact and foreign languages were significant predictors of participation, whereas academic, self-development, and career-related motives were not, contrary to previous findings. The second objective was to measure the perceived effects of participation in IMPs. Three types of effects were reported: self-development, cultural awareness and career advancement. Participation in IMPs had a broader impact on the graduates’ lives and careers than previously reported.  相似文献   

A "dry and wet hybrid" lithography technique for multilevel replication templates: Applications to microfluidic neuron culture and two-phase global mixing     

Paul D  Saias L  Pedinotti JC  Chabert M  Magnifico S  Pallandre A  De Lambert B  Houdayer C  Brugg B  Peyrin JM  Viovy JL 《Biomicrofluidics》2011,5(2):24102

A broad range of microfluidic applications, ranging from cell culture to protein crystallization, requires multilevel devices with different heights and feature sizes (from micrometers to millimeters). While state-of-the-art direct-writing techniques have been developed for creating complex three-dimensional shapes, replication molding from a multilevel template is still the preferred method for fast prototyping of microfluidic devices in the laboratory. Here, we report on a "dry and wet hybrid" technique to fabricate multilevel replication molds by combining SU-8 lithography with a dry film resist (Ordyl). We show that the two lithography protocols are chemically compatible with each other. Finally, we demonstrate the hybrid technique in two different microfluidic applications: (1) a neuron culture device with compartmentalization of different elements of a neuron and (2) a two-phase (gas-liquid) global micromixer for fast mixing of a small amount of a viscous liquid into a larger volume of a less viscous liquid.  相似文献

Kinematic and kinetic comparisons between American and Korean professional baseball pitchers     

Escamilla R  Fleisig G  Barrentine S  Andrews J  Moorman C 《Sports biomechanics / International Society of Biomechanics in Sports》2002,1(2):213-228

The purpose of this study was to quantify and compare kinematic, temporal, and kinetic characteristics of American and Korean professional pitchers in order to investigate differences in pitching mechanics, performance, and injury risks among two different cultures and populations of baseball pitchers. Eleven American and eight Korean healthy professional baseball pitchers threw multiple fastball pitches off an indoor throwing mound positioned at regulation distance from home plate. A Motion Analysis three-dimensional automatic digitizing system was used to collect 200 Hz video data from four electronically synchronized cameras. Twenty kinematic, six temporal, and 11 kinetic variables were analyzed at lead foot contact, during the arm cocking and arm acceleration phases, at ball release, and during the arm deceleration phase. A radar gun was used to quantify ball velocity. At lead foot contact, the American pitchers had significantly greater horizontal abduction of the throwing shoulder, while Korean pitchers exhibited significantly greater abduction and external rotation of the throwing shoulder. During arm cocking, the American pitchers displayed significantly greater maximum shoulder external rotation and maximum pelvis angular velocity. At the instant of ball release, the American pitchers had significantly greater forward trunk tilt and ball velocity and significantly less knee flexion, which help explain why the American pitchers had 10% greater ball velocity compared to the Korean pitchers. The American pitchers had significantly greater maximum shoulder internal rotation torque and maximum elbow varus torque during arm cocking, significantly greater elbow flexion torque during arm acceleration, and significantly greater shoulder and elbow proximal forces during arm deceleration. While greater shoulder and elbow forces and torques generated in the American pitchers helped generate greater ball velocity for the American group, these greater kinetics may predispose this group to a higher risk of shoulder and elbow injuries.  相似文献   

Nomographs and filters     

Joe N. Hallberg  Claude S. Lindquist 《Journal of The Franklin Institute》1976,302(2):111-145

This paper presents the nomographs for additional classical filters, including ultraspherical, Legendre, modified associated Legendre, Papoulis, Halpern, Bessel, Gaussian, and synchronously-turned. It also identifies inaccuracies in the earlier nomographs. The basic theory of nomographs and their utilization in developing filter nomographs is presented.  相似文献   

Motor tests for primary school aged children: A systematic review     

Claude Scheuer  Christian Herrmann  Andreas Bund 《Journal of sports sciences》2019,37(10):1097-1112

Motor testing in education has gained in relevance in light of recent developments in educational systems (Köller & Baumert, 2012). The purpose of this systematic review was to identify studies using motor tests in primary school children aged 4 to 12 years and to synthetize information about the quality and application of the test instruments used. A systematic review of 910 records identified by a search of nine databases yielded 144 papers reporting motor testing in primary school age children, including 25 articles reporting on the quality of 20 test instruments. In the selected articles, tests grounded on the constructs of “motor abilities” and/or “motor skills” are the most frequent and are mostly used for monitoring purposes or for impact research. Tests based on the construct “motor competencies” have become popular only recently, being relevant for educational motor testing due to their curricular validity. The test instruments have been investigated towards their validity and reliability to different extents. However, for several test instruments factorial validity has not been established and more validation studies are needed to improve their psychometric quality especially if used in educational contexts.  相似文献   

Defining sport tourism: a content analysis of an evolving epistemology     

Derek Van Rheenen  Sorina Cernaianu  Claude Sobry 《Journal of Sport Tourism》2017,21(2):75-93

ABSTRACT

This paper conducts a systematic evaluation of one of the primary journals in the field of sport tourism research since its establishment in 1993. Drawing on extant literature with varying disciplinary approaches, this meta-review traces the development of key concepts and definitions underlying an evolving epistemology connected to sport tourism, as evidenced within the Journal of Sport & Tourism (JS&T). It does so by examining research specific to content previously unexplored. The study first conducted a content analysis based upon a keyword search, focusing on phrases in which sport and tourism appeared together. The study reviewed all texts, including articles, book chapters and editorials (n?=?517), for the years 1993–2014. We then constructed a thematic analysis based upon the most common defining elements found within these texts. These extracted definitions were analyzed according to their paradigmatic elements. Based on these findings, this paper suggests the need to further define the epistemological boundaries of sport tourism for the twenty-first century.  相似文献
