Reflexivity,positionality and power in cross-cultural participatory action research with research assistants in rural Cambodia     

Kim Ozano  Rose Khatri 《Educational Action Research》2018,26(2):190-204

This paper draws on the experiences of a doctoral student undertaking a cross-cultural, cross-language participatory action research (PAR) project in rural Cambodia. Cambodia is a largely Buddhist country with a complex history of religion, invasion, colonisation, war and oppression. Despite a democratic constitution, political control and fear of challenging authority are ever present; and all had an impact on the participation and development of this project. I recruited eight volunteer community health workers (CHWs) and two research assistants (RAs) with an aim to explore methods and challenges faced when trying to improve health with and for community members. Over eight participatory workshops and a two-day training session CHWs identified, implemented and reflected on solutions to community health problems. Simultaneously, the RAs and I reflected on the processes and challenges we faced. Creating opportunity for reflexivity allowed for discussion to emerge around culture, position and power and how these were impacting on the research process and outcomes. Established social hierarchical power structures in Cambodia presented challenges to undertaking a PAR project with emancipatory and social change aims. Such structures also impacted on the ability and readiness of participants to be critical and analytical. The importance of the RAs as cultural navigators and the necessity of embracing their situated knowledge as both an insider and outsider is a key finding.  相似文献   

Is there a startup wage premium? Evidence from MIT graduates     

J. Daniel Kim 《Research Policy》2018,47(3):637-649

While startups are the center of extensive policy discussion given their outsized role in job creation, it is not clear whether they create high quality jobs relative to incumbent firms. This paper investigates the wage differential between venture capital-backed startups and established firms, given that the two firm types compete for talent. Using data on MIT graduates, I find that non-founder employees at VC-backed startups earn roughly 10% higher wages than their counterparts at established firms. To account for unobserved heterogeneity across workers, I exploit the fact that many MIT graduates receive multiple job offers. I find that wage differentials are statistically insignificant from zero when individual fixed effects are included. This implies that much of the startup wage premium in the cross-section can be attributed to selection, and that VC-backed startups pay competitive wages for talent. To unpack the selection mechanism, I show that individual preferences for risk as well as challenging work strongly predict entry into VC-backed startups.  相似文献

Li-ion battery material under high pressure: amorphization and enhanced conductivity of Li4Ti5O12     

Yanwei Huang  Yu He  Howard Sheng  Xia Lu  Haini Dong  Sudeshna Samanta  Hongliang Dong  Xifeng Li  Duck Young Kim  Ho-kwang Mao  Yuzi Liu  Heping Li  Hong Li  Lin Wang 《国家科学评论(英文版)》2019,6(2):239

Lithium titanium oxide (Li₄Ti₅O₁₂, LTO), a ‘zero-strain’ anode material for lithium-ion batteries, exhibits excellent cycling performance. However, its poor conductivity highly limits its applications. Here, the structural stability and conductivity of LTO were studied using in situ high-pressure measurements and first-principles calculations. LTO underwent a pressure-induced amorphization (PIA) at 26.9 GPa. The impedance spectroscopy revealed that the conductivity of LTO improved significantly after amorphization and that the conductivity of decompressed amorphous LTO increased by an order of magnitude compared with its starting phase. Furthermore, our calculations demonstrated that the different compressibility of the LiO₆ and TiO₆ octahedra in the structure was crucial for the PIA. The amorphous phase promotes Li⁺ diffusion and enhances its ionic conductivity by providing defects for ion migration. Our results not only provide an insight into the pressure depended structural properties of a spinel-like material, but also facilitate exploration of the interplay between PIA and conductivity.  相似文献

An analysis of the development and use of theory in library and information science research articles     

Sung-Jin Kim  Dong Y. Jeong 《Library & information science research》2007,28(4):548-562

This study identifies the state and characteristics of theoretical research in library and information science journals by examining the number and the quality of theory incidents. Theory incident is characterized as an event in which the author contributes to the development or the use of theory in his/her own paper. This study assumes that both theory building and theory use are intertwined to construct a cohesive body of knowledge in the filed. Theory incidents were identified by a content analysis of 1661 articles in four LIS journals from 1984 to 2003. The findings suggest that 41.4% of the articles contributed to the development or use of theory. The overall proportion of theoretical articles has increased. They showed a tendency to converge into a few subfields, such as information seeking and use or information retrieval. However, the declining share of theory development articles in recent journal issues and the overall low level of theory incidents are urging LIS researchers to the importance of continuous and creative research in LIS.  相似文献   

Where do alliances come from?: The effects of upper echelons on alliance formation     

Jerry W. Kim  Monica C. Higgins 《Research Policy》2007,36(4):499-514

Alliances with established organizations provide young firms with resources necessary for survival. We build on recent organizational research examining the effect of upper echelons on attracting powerful intermediaries to understand how young biotechnology firms establish alliances with established organizations. Drawing upon the concept of homophily, we test hypotheses regarding the extent to which young firms and partners match along specific homophily dimensions. Our findings from an event-history analysis of 3,200 career histories of managers who took biotechnology firms public between 1979 and 1996 show that alliance formation is related to status homophily and role-based homophily between young and established organizations.  相似文献   

Patent document categorization based on semantic structural information     

Jae-Ho Kim  Key-Sun Choi 《Information processing & management》2007

The number of patent documents is currently rising rapidly worldwide, creating the need for an automatic categorization system to replace time-consuming and labor-intensive manual categorization. Because accurate patent classification is crucial to search for relevant existing patents in a certain field, patent categorization is a very important and useful field. As patent documents are structural documents with their own characteristics distinguished from general documents, these unique traits should be considered in the patent categorization process. In this paper, we categorize Japanese patent documents automatically, focusing on their characteristics: patents are structured by claims, purposes, effects, embodiments of the invention, and so on. We propose a patent document categorization method that uses the k-NN (k-Nearest Neighbour) approach. In order to retrieve similar documents from a training document set, some specific components to denote the so-called semantic elements, such as claim, purpose, and application field, are compared instead of the whole texts. Because those specific components are identified by various user-defined tags, first all of the components are clustered into several semantic elements. Such semantically clustered structural components are the basic features of patent categorization. We can achieve a 74% improvement of categorization performance over a baseline system that does not use the structural information of the patent.  相似文献
