Becoming an academic: the role of doctoral capital in the field of education     

Jude Walker  EeSeul Yoon 《高等教育研究与发展》2017,36(2):401-415

This paper draws on Bourdieu’s concepts of field, capital and habitus to examine the learning and enculturation of alumni of a Canadian PhD programme in the discipline of Education. We introduce the concept of doctoral capital to help explain how and why some PhD graduates go on to secure faculty positions and others do not. Our research suggests that certain existing and acquired academic practices, attributes, dispositions and behaviours collectively form a type of doctoral capital that alumni can then use in the academic marketplace.  相似文献   

Grounded blends and mathematical gesture spaces: developing mathematical understandings via gestures     

Caroline Yoon  Michael O. J. Thomas  Tommy Dreyfus 《Educational Studies in Mathematics》2011,78(3):371-393

This paper examines how a person’s gesture space can become endowed with mathematical meaning associated with mathematical spaces and how the resulting mathematical gesture space can be used to communicate and interpret mathematical features of gestures. We use the theory of grounded blends to analyse a case study of two teachers who used gestures to construct a graphical anti-derivative while working on a professional development task in a calculus modelling activity. Results indicate that mathematical gesture spaces can encourage mathematical experimentation, lighten the cognitive load for students and can be limited by a person’s physical constraints.  相似文献   

Theory development and convergence of human resource fields: Implications for human performance technology     

Yonjoo Cho  Seung Won Yoon 《Performance Improvement Quarterly》2010,23(3):39-56

This study examines major theory developments in human resource (HR) fields and discusses implications for human performance technology (HPT). Differentiated HR fields are converging to improve organizational performance through knowledge‐based innovations. Ruona and Gibson (2004) made a similar observation and analyzed the historical evolution and convergence of three HR‐related fields: human resource management (HRM), human resource development (HRD), and organization development (OD). A field left out in their analysis is HPT. Many learning professionals recognize HPT as a more comprehensive approach to improving organizational performance issues (Molenda & Pershing, 2008; Pershing, 2006). However, little research has been done to advance the theory development of HPT and discuss its relationships within HR fields. This study adds a new perspective to that of Ruona and Gibson's historical analysis of HR fields by examining convergence issues from a theory development perspective.  相似文献   

Effects of forefoot bending stiffness of badminton shoes on agility,comfort perception and lower leg kinematics during typical badminton movements     

Sang-Kyoon Park  Wing-Kai Lam  Sukhoon Yoon  Ki-Kwang Lee 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(3):374-386

This study investigated whether an increase in the forefoot bending stiffness of a badminton shoe would positively affect agility, comfort and biomechanical variables during badminton-specific movements. Three shoe conditions with identical shoe upper and sole designs with different bending stiffness (Flexible, Regular and Stiff) were used. Elite male badminton players completed an agility test on a standard badminton court involving consecutive lunges in six directions, a comfort test performed by a pair of participants conducting a game-like practice trial and a biomechanics test involving a random assignment of consecutive right forward lunges. No significant differences were found in agility time and biomechanical variables among the three shoes. The players wearing the shoe with a flexible forefoot outsole demonstrated a decreased perception of comfort in the forefoot cushion compared to regular and stiffer conditions during the comfort test (p < 0.05). The results suggested that the modification of forefoot bending stiffness would influence individual perception of comfort but would not influence performance and lower extremity kinematics during the tested badminton-specific tasks. It was concluded that an optimisation of forefoot structure and materials in badminton shoes should consider the individual’s perception to maximise footwear comfort in performance.  相似文献   

民勤绿洲农户生计资本与生计障碍调查研究     

李勇进  王诗琪  陈文江 《科学．经济．社会》2014,(1):135-140

本文基于英国国际发展部(DFID)提出的"可持续生计框架"对民勤绿洲农村家庭的生计资本进行了问卷调查,对生计障碍的成因进行了分析。我们把农户生计资本与生计策略之间出现断裂的情况定义为生计障碍。在生计资产脆弱的现实背景下,"关井压田"等节水政策的实施在短期内直接降低了农户的收入,加上经济补偿性政策实施效果的延时性,强化了当地农户的生计障碍,同时也让环境保护政策效果的发挥受到一定程度的限制。为了降低农户生计的脆弱性,在进一步的环境保护政策实施过程中需要增加对农户生计资本与生计策略协调度的关注才能使农户生计"可持续"改善成为可能。  相似文献   

Age Differences in Online Social Networking: Extending Socioemotional Selectivity Theory to Social Network Sites     

Pamara F. Chang  Yoon Hyung Choi  Natalya N. Bazarova  Corinna E. Löckenhoff 《广播与电子媒介杂志》2015,59(2):221-239

This article extends socioemotional selectivity theory to online social networking by examining age differences in the size and composition of Facebook networks across a wide age range of Facebook users (18 to 93 years old) in a nationally representative sample. Findings suggest increasing selectivity of Facebook social partners with age. Compared to younger adults, friend networks of older adults are smaller but contain a greater proportion of individuals who are considered to be actual friends. Moreover, a higher proportion of actual to total Facebook friends is associated with lower levels of social isolation and loneliness across the life span.  相似文献   

Traceable clonal culture and chemodrug assay of heterogeneous prostate carcinoma PC3 cells in microfluidic single cell array chips     

Jaehoon Chung  Patrick N. Ingram  Tom Bersano-Begey  Euisik Yoon 《Biomicrofluidics》2014,8(6)

Cancer heterogeneity has received considerable attention for its role in tumor initiation and progression, and its implication for diagnostics and therapeutics in the clinic. To facilitate a cellular heterogeneity study in a low cost and highly efficient manner, we present a microfluidic platform that allows traceable clonal culture and characterization. The platform captures single cells into a microwell array and cultures them for clonal expansion, subsequently allowing on-chip characterization of clonal phenotype and response against drug treatments. Using a heterogeneous prostate cancer model, the PC3 cell line, we verified our prototype, identifying three different sub-phenotypes and correlating their clonal drug responsiveness to cell phenotype.  相似文献   

Expectations of and Attitudes toward Counseling: A Comparison of Asian International and U.S. Graduate Students   总被引：1，自引：1，他引：0  

Eunju Yoon  David A. Jepsen 《International journal for the advancement of counseling》2008,30(2):116-127

This study examined Asian international graduate students’ expectations of and attitudes toward counseling by using U.S. graduate students as a comparative reference group. Survey data from 189 Asian international and 186 U.S. students were subject to analyses. Results indicated that Asian international students, in comparison with U.S. students, indicated less exposure to counseling, less self-perceived need for counseling, greater discomfort/shame with counseling, less openness to counseling, a greater preference for a directive style, and a greater preference for a flexible counseling format. Language and cultural concerns were barriers to seeking counseling. Implications for culturally responsive services were discussed.  相似文献

What Do Learning Scientists Do? A Survey of the ISLS Membership     

Susan A. Yoon  Cindy E. Hmelo-Silver 《学习科学杂志》2017,26(2):167-183

This study responds to a question that people working in the field of learning sciences get asked regularly: What do learning scientists do? Earlier attempts to answer this question came from a need to define a new field of educational research. Now that the International Society of the Learning Sciences (ISLS) has grown into a robust and productive society, it is time to gain a more nuanced understanding of learning sciences research and practices—including where it takes place, for whom, and in what form—as defined by members of the learning sciences community. Here we report on the responses of 253 ISLS members to a survey conducted in 2014. We discuss implications of the findings in terms of the type of impact learning scientists have. We also discuss how these results might be used to advise prospective students and to create a vision for our future.  相似文献
