Meritocratic Epistemic Communities: An Alternative Policy Paradigm for Higher Education          下载免费PDF全文

Seungchan Choi 《Higher Education Quarterly》2015,69(1):58-78

This paper attempts to propose an alternative policy frame for higher education policy by demonstrating the inadequacy of the market approach adopted by the 2011 English higher education policy in addressing the economic and social agenda, and by reframing higher education as a mechanism that selects and distributes talents to vocational sectors in a way that achieves socially optimal outcomes. The paper shows why government control is more appropriate than market mechanism in managing higher education cost, how effective screening and distribution of talents can be achieved through deliberation among epistemic community members and how the alternative policy frame supports a social justice agenda. The idea of a meritocratic epistemic community for screening and educating talents is central to this new frame as it facilitates the creation of a common space where competing stakeholders of one vocational sector gather together to deliberate on the merits of the future workforce.  相似文献   

Influence of Cultural Orientations on Electronic Word-of-Mouth (eWOM) in Social Media     

Youngtae Choi 《Journal of Intercultural Communication Research》2019,48(3):292-313

This study explores how horizontal/vertical individualism and collectivism (HVIC) orientations influence electronic word-of-mouth (eWOM) (i.e., opinion leadership and opinion seeking) in social media. Online survey panel data through Amazon MTurk were collected from American social media users to address the research purpose. The results, using the structural equation modeling, show that the paths from horizontal individualism to opinion leadership, vertical individualism to opinion leadership and opinion seeking, horizontal collectivism to opinion leadership, and vertical collectivism to opinion leadership and opinion seeking were significant. This study provides theoretical and managerial implications regarding the influence of HVIC orientations on eWOM in social media.  相似文献   

Relationship between foot strike pattern,running speed,and footwear condition in recreational distance runners     

Roy T. H. Cheung  Rodney Y. L. Wong  Tim K. W. Chung  R. T. Choi  Wendy W. Y. Leung  Diana H. Y. Shek 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(2):238-247

Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury.  相似文献   

New paint,new challenges: Conservation of Roy Lichtenstein's outdoor sculpture House I     

Nani Lew  Jihyun Choi 《文物保护研究》2016,61(3):114-119

This paper deals with the conservation of Roy Lichtenstein's outdoor sculpture House I, conducted at Leeum, Samsung Museum of Art, Seoul, Korea. Having suffered from direct sunlight for more than a decade, the work presented severe paint fading and chalking. The purpose of the project was to provide the best possible protection by applying a durable paint material, while simultaneously preserving the colored surface that Lichtenstein had intended. A marine paint, which is relatively durable and was also utilized by the artist himself, was selected for the repainting system. An absence of practical experience and knowledge in Korea in relation both to the marine paint and its application led to many difficulties. During the actual application of the new paint, numerous technical problems arose which had to be solved in order to carry out the conservation treatment. To meet this demand, a close adherence to technical practice and an interdisciplinary study were carried out to provide the necessary understanding and compromise.  相似文献

Noise Levels in Hong Kong Primary Schools: Implications for classroom listening     

Ching Yee Choi 《International Journal of Disability, Development & Education》2005,52(4):345-360

Many researchers have stressed that the acoustic environment is crucial to the speech perception, academic performance, attention, and participation of students in classrooms. Classrooms in highly urbanised locations are especially vulnerable to noise, a major influence on the acoustic environment. The purpose of this investigation was to determine noise levels in one such urban environment, Hong Kong. The ambient noise level, and its relationship to the speech intensity levels of both teachers and students was surveyed in 47 primary school classrooms. Moreover, the presence of acoustical treatments for noise reduction and the use of classroom amplification systems were documented for each classroom. The survey found that the mean occupied noise level was 60.74 dB (A); the mean unamplified and amplified speech‐to‐noise ratios of teachers were 13.53 dB and 18.45 dB, respectively; while the mean unamplified speech‐to‐noise ratio for students was 4.13 dB. Most of the classrooms exhibited insufficient acoustical treatments to provide significant noise reduction. The listening environment in many Hong Kong primary schools was not favourable for optimal classroom learning. Recommendations for improving the acoustical environment in classrooms in highly urbanised locations such as Hong Kong are discussed.  相似文献   

Continuity of Care,Caregiver–Child Interactions,and Toddler Social Competence and Problem Behaviors     

Karen Ruprecht  James Elicker  Ji Young Choi 《Early education and development》2016,27(2):221-239

ABSTRACT

Research Findings: Continuity of care is a recommended practice in child care intended to promote secure and supportive relationships between infants and toddlers and their caregivers. Toddlers (N = 115) between 12 and 24 months were observed in 30 continuity and 29 noncontinuity classrooms. The average duration of care for toddlers with caregivers was 14 months in the continuity rooms and 5 months in noncontinuity rooms. Toddlers observed in continuity rooms experienced higher levels of interactive involvement with their caregivers and were rated by their caregivers as having fewer problem behaviors compared with the toddlers in noncontinuity rooms. Toddlers in rooms with higher staff–child ratios also experienced more involved caregiving. We did not find evidence that the level of involved caregiving mediated the association between continuity of care and toddlers’ social competence or problem behaviors. Practice or Policy: Continuity of care may be a promising practice for programs that strive to provide high-quality care for infants and toddlers.  相似文献   

Collagen-based brain microvasculature model in vitro using three-dimensional printed template     

Jeong Ah Kim  Hong Nam Kim  Sun-Kyoung Im  Seok Chung  Ji Yoon Kang  Nakwon Choi 《Biomicrofluidics》2015,9(2)

We present an engineered three-dimensional (3D) in vitro brain microvasculature system embedded within the bulk of a collagen matrix. To create a hydrogel template for the functional brain microvascular structure, we fabricated an array of microchannels made of collagen I using microneedles and a 3D printed frame. By culturing mouse brain endothelial cells (bEnd.3) on the luminal surface of cylindrical collagen microchannels, we reconstructed an array of brain microvasculature in vitro with circular cross-sections. We characterized the barrier function of our brain microvasculature by measuring transendothelial permeability of 40 kDa fluorescein isothiocyanate-dextran (Stoke''s radius of ∼4.5 nm), based on an analytical model. The transendothelial permeability decreased significantly over 3 weeks of culture. We also present the disruption of the barrier function with a hyperosmotic mannitol as well as a subsequent recovery over 4 days. Our brain microvasculature model in vitro, consisting of system-in-hydrogel combined with the widely emerging 3D printing technique, can serve as a useful tool not only for fundamental studies associated with blood-brain barrier in physiological and pathological settings but also for pharmaceutical applications.  相似文献   

Culturally Responsive Counseling for Asian Americans: Clinician Perspectives     

Mikyong?Kim-GohEmail author  Hyunmi?Choi  Myeong?Sook?Yoon 《International journal for the advancement of counseling》2015,37(1):63-76

Research has consistently found acute mental health treatment disparities among Asian Americans. One proposed reason for the underutilization of mental health services by Asian Americans is that available services are not culturally competent. This exploratory study presents qualitative data gathered from interviews with professional counselors who serve Asian American clients. Findings revealed significant barriers to counseling due to cultural stigma and shame, suppression of emotions, and communication gaps between clients and counselors. In response, clinicians frequently made adjustments to therapeutic approaches to accommodate the cultural beliefs and practices of clients and families. Implications for practice and research are discussed.  相似文献   

Study for optical manipulation of a surfactant-covered droplet using lattice Boltzmann method     

Se Bin Choi  Sasidhar Kondaraju  Joon Sang Lee 《Biomicrofluidics》2014,8(2)

In this study, we simulated deformation and surfactant distribution on the interface of a surfactant-covered droplet using optical tweezers as an external source. Two optical forces attracted a single droplet from the center to both sides. This resulted in an elliptical shape deformation. The droplet deformation was characterized as the change of the magnitudes of surface tension and optical force. In this process, a non-linear relationship among deformation, surface tension, and optical forces was observed. The change in the local surfactant concentration resulting from the application of optical forces was also analyzed and compared with the concentration of surfactants subjected to an extensional flow. Under the optical force influence, the surfactant molecules were concentrated at the droplet equator, which is totally opposite to the surfactants behavior under extensional flow, where the molecules were concentrated at the poles. Lastly, the quasi-equilibrium surfactant distribution was obtained by combining the effects of the optical forces with the extensional flow. All simulations were executed by the lattice Boltzmann method which is a powerful tool for solving micro-scale problems.  相似文献
