Constellations of risk factors as moderators of the impact of a randomized intervention on students’ reading skills in rural India     

《Studies in Educational Evaluation》2019

Individual, family and community risk factors might determine the success or failure of educational interventions. The study is a secondary analysis, aimed at identifying distinctive constellations of risk for educational attainment, and at exploring whether membership to these constellations moderated the impact of a cluster-randomized reading intervention in rural India. By means of latent profile analysis, four constellations of risk were identified based on individual and family risk-factors. Multilevel cumulative logit models confirmed that the intervention had a positive impact on the outcome, and revealed that profile membership did not moderate the effect of the intervention. However more nuanced analysis showed that the intervention worked differently for children with different risk-profiles depending on contextual factors.  相似文献

陈伟炯  王茂馨 《科技管理研究》2020,40(1):215-220

首先运用流程图法分析造成物联网环境下医药冷链物流各环节风险的众多因素源,并运用熵权法对风险指标客观赋权建立风险因素评估指标体系,然后利用Ge NIe软件建立动态贝叶斯网络模型对风险环节的关键风险因素进行概率评估。结果显示在风险评估中运输环节风险的发生概率最高,同时企业关于设备的验证选型是影响物联网医药冷链的关键风险因素,这为企业和政府控制药品质量安全管理提供了依据。  相似文献   

Queer Intercultural Relationality: An Autoethnography of Asian–Black (Dis)Connections in White Gay America     

Shinsuke Eguchi 《Journal of International and Intercultural Communication》2015,8(1):27-43

For this critical intercultural inquiry, I as an Asian/Japanese transnational cisgendered gay man write my autoethnography of queer (or non-heteronormative) Asian–Black (dis)connections. Specifically, I challenge, interrogate, and problematize my queer intercultural production of desire and attraction as I engage in my critical autoethnographic interrogation of dialogues with five Asian/Japanese transnational gay men who have previously engaged in queer Asian–Black relationality. In so doing, I intend to create a potential point of departure to decenter the discursive and material effects of White gay normativity in the knowledge production of Asian queer male desire and attraction.  相似文献

Influence of organization learning on innovation output in manufacturing firms in Kenya     

《国际创新研究学报(英文)》2020,4(1):16-26

Knowledge entrepreneurship is increasingly becoming important in driving innovation for high levels of competitiveness. The purpose of this study was to investigate the relationship between Organization Learning (OL) and Innovation Output (IO) for improved performance in manufacturing firms in Kenya. The theoretical underpinnings on this study are the Schumpeter’s (1934) innovation theory of and the Gleick (1987) complexity theory. The methodology used was mixed method research because it provides a more holistic understanding of a thematic area. The research design that was used is cross-sectional design because it allows for making observations on different characteristics that exist within a group at a particular time. The target population was manufacturing firms across the country. Multi-stage sampling strategy was used to sample 303 respondents from 101 firms. Primary and secondary data were used to collect both qualitative and quantitative data. The questionnaire, interview schedule and a checklist of key informants were used to collect data. Content validity was used to ascertain the credibility of the research procedure and internal consistency technique was used to test for reliability. Correlation and linear regression were used to determine the relationship between OL and IO. Work disruptions were avoided by making prior arrangements and appointments. The findings indicate that OL has a significant influence on IO. It is recommended that lifelong learning, management support and risk tolerance should be encouraged to improve creativity. High creativity is important in raising the capacity to integrate internal and external knowledge for greater levels of IO. Further research should be carried out to find how customers and suppliers information can be utilized to enriched OL.  相似文献   

Minority Cultures and Social Media: Magnifying Garifuna     

《Journal of Intercultural Communication Research》2013,42(4):319-339

This paper looks at social media use by the Garifuna people. It explores how they are using social media to create a supraterritorial cyberscape. Despite the claim that global media is marginalising minority cultures and causing global homogenisation, this research found that newer forms of social media are in fact creating virtual cultural cyberscapes that are extending minority cultures. The Garifuna cultural response to social media can be demonstrative of the positive impact of social media minority perspectives. The larger implication, though, is that traditional geographical models of cultural space are becoming obsolete. In this research, a total of 60 Garifuna in locations all across the United States and Honduras were selected for participation. Their access to and use of media were examined.  相似文献   

Editor's introduction to the forum on defining applied communication scholarship     

Dan O'Hair Editor 《Journal of Applied Communication Research》2013,41(2):164-165

Although public meetings are a frequent method of public participation and risk communication, little research investigates what citizens think about their use in environmental management. To examine satisfaction with public meetings, residents of two neighboring communities received questionnaires following a public meeting about a local landfill. Respondents included residents who did and did not attend the meeting. Irrespective of whether respondents had ever attended a public meeting, meeting expectations and perceptions of relational/informational communication at meetings, including whether respondents thought meeting organizers were genuinely interested in participants' comments or meetings were informative, predicted satisfaction. Perceived risk associated with the recent meeting's topic and credibility of government agencies that frequently conduct meetings also predicted satisfaction.  相似文献   

Intergroup Contact,Media Exposure,and Racial Attitudes     

《Journal of Intercultural Communication Research》2013,42(1):54-72

The present investigation uses intergroup contact and media systems’ dependency theories to illuminate the relative significance of various sources of information in shaping Caucasian-American attitudes toward African-Americans. It uses empirical data from an exploratory survey of college students to build a chain of related variables that link primary sources of information (face-to-face versus mediated) to stereotypical beliefs, perceived internal causal attributions for African-Americans’ failures, and prejudicial feelings toward African-Americans. Results suggest that face-to-face sources of racial/ethnic out-group information are more effective than mediated sources in prejudice reduction. The discussion includes theoretical and practical implications of the findings.  相似文献   

The Story of Two Big Chimneys: A Frame Analysis of Climate Change in US and Chinese Newspapers     

《Journal of Intercultural Communication Research》2013,42(2):151-177

Despite mounting research on how the news media portrayed climate change in developed countries, disproportionately little attention was paid to one of the top greenhouse gas emitters in the world—China. This study systematically examined and compared how the US and Chinese newspapers portrayed climate change. An analytical framework, grounded in framing research traditions, took into account both theoretical and practical challenges in frame analysis by creating a hybrid structure of interlocked generic and issue-specific frames. The results showed both convergent and divergent pictures from the two countries’ newspapers shaped distinctly by the sociopolitical realities in both countries. The research also cautioned against making simplistic explanations of the results and offered culturally informed interpretations. A discussion on better research focus and design was offered for future research in this avenue.  相似文献
