Unraveling the relationships between smartphone use,exposure to heterogeneity,political efficacy,and political participation: a mediation model approach     

Chang Sup Park  Kavita Karan 《亚洲交流杂志》2013,23(4):370-389

This paper assesses how use of smartphones relates to exposure to heterogeneity, political efficacy, and political engagement and suggests a new mediation model that can be applied to mobile communication. Drawing on online survey data collected during the 2012 presidential election in South Korea, this study finds that exposure to heterogeneity and political efficacy jointly mediate the impact of informational uses of smartphones on political participation. The current study also shows that informational uses of smartphones are significantly related to encounters with heterogeneity, political efficacy, and participatory behaviors. Additionally, recreational uses of smartphones were found to have a positive association with exposure to heterogeneity. However, relational uses of smartphones were not associated with democratic outcomes. The findings suggest that smartphones, by increasing the possibility of encountering diversity and subsequently enhancing political efficacy, create an additional pathway to citizen engagement in democratic processes.  相似文献   

The Impact of Quality on Satisfaction,Revenue, and Cost as Perceived by Providers of Higher Education     

Abhay Shah 《Journal of Marketing for HIGHER EDUCATION》2013,23(2):125-141

Researchers have found a strong relationship between improvements in quality and satisfaction, revenue, and cost. However, no study to date investigates the same for higher education. This study investigates whether institutions of higher education have implemented quality improvement programs, and if so, if the results are similar to what has been observed with firms in the private sector. The study proposes and tests five hypotheses, and findings support four of the five hypotheses, with partial support for the fifth hypothesis. The study finds that implementing quality programs leads to an increase in satisfaction among constituent groups, increase in revenue, and a reduction in costs. The findings also show that increased satisfaction (due to improved quality) also leads to increase in revenue and reduction in costs.  相似文献   

Glimpses of a century-old story     

Jasmine M. Shah 《Resonance》2013,18(4):336-344

The story of Agrobacterium has been widely discussed for over a century. Fridiano Cavara in 1897 first described the occurrence of plant-derived tumors with bacterial origin. Detailed molecular analysis of this microbe accelerated in the last 30 years and it gained worldwide acceptance as a ‘natural genetic engineering tool’. This tool has an interesting history starting from the tumors that it makes, nomenclature, genome, pathogenicity and DNA transfer, to its economic importance. This review is a glimpse of some basic and interesting facts of the unique Agrobacterium.  相似文献   

Private for-profit higher education in Australia: widening access,participation and opportunities for public-private collaboration     

Mahsood Shah  Chenicheri Sid Nair 《高等教育研究与发展》2013,32(5):820-832

Private for-profit higher education has grown rapidly in many parts of the world. This growth is attributed to many factors, including a broadening of the student population and the recognition that wider access to higher education will be economically beneficial to individuals, governments and society as a whole. In Australia, the number of students in private for-profit higher education is rising, with dramatic projections for the next 10 years. The Australian government has set a target to increase the participation of students in higher education, with a focus on increasing the access and success of students from disadvantaged backgrounds. It is unclear, however, what role the burgeoning private for-profit institutions will play in meeting the government's targets, and what incentives will be provided for them to increase the access and participation of students from disadvantaged groups. This paper analyses the key drivers of growth in private for-profit higher education in Australia, and discusses issues around quality and standards. It examines the strengths and limitations of the sector, and the extent to which it contributes to diversity, access and the participation of students from disadvantaged backgrounds. It argues that the sector needs clear government directions to improve levels of access, and new government policies to encourage public-private collaborations to help ensure sustainability. The paper also briefly touches on the need for a review into the current structure of Australia's higher education sector as a whole, and whether higher education would benefit from the formation of public community colleges with the explicit aim of widening access for disadvantaged student groups. Further, the paper suggests that encouraging such public-private collaboration may be beneficial to ensure access and participation of students from all walks of life, including disadvantaged groups.  相似文献   

Research agenda for social and collaborative information seeking     

Chirag Shah  Rob Capra  Preben Hansen 《Library & information science research》2017,39(2):140-146

Scholars in diverse fields of inquiry have identified the need to expand individual-based information seeking and behavior models and systems to incorporate social as well as collaborative dimensions. However, the research areas of Social Information Seeking (SIS) and Collaborative Information Seeking (CIS) have been largely disconnected from one another despite a few notable attempts to study them under one umbrella. Researchers in these communities have recently realized the value of bringing SIS and CIS together for two main reasons: often it is impossible to separate social and collaborative dimensions in a project; and by considering these two aspects of information seeking, we may be able to support human information behavior in ways not previously possible. A brief synthesis of work in the domains of SIS and CIS is presented here. Then, an integrated view is presented to consider Social and Collaborative Information Seeking (SCIS) as an intersection and extension of SIS and CIS. Benefits of this approach are discussed and the integrated view is used as the basis to present a research agenda that outlines opportunities and challenges unique to SCIS.  相似文献

Standardization of homocysteine on HPLC using DTT as reductant     

Tester F. Ashavaid  Farah F. Eghlim  Kavita K. Shalia  Kappiareth G. Nair 《Indian journal of clinical biochemistry : IJCB》2003,18(2):106-110

Determination of plasma total homocysteine by high-pressure liquid chromatography (HPLC) usually requires reduction of protein bound or free homocysteine-disulphides into thiols by a reducing agent and the liberated thiols are then derivatized by a fluorescent marker. In this study we have standardized the HPLC method for homocysteine measurement using dithiothreitol (DTT) as reductant. The results of plasma total homocysteine values obtained by HPLC were compared with IMx method. The difference between the two means was statistically insignificant [P=0.616847 (two tail)] Linear regression analysis showed strong correlation between the two methods (r=0.983). Using this method we have analyzed 132 controls and 130 Coronary Heart Disease (CHD) patients for plasma total homocysteine, wherein, the mean plasma total homocysteine levels were 10.51±8.36 and 11.51±10.06 μmol/L respectively. Our research study suggests that DTT method is a simple and inexpensive assay for homocysteine determination in human plasma for research application.  相似文献   

Canada’s Implementation of the Right to Education for Students with Disabilities     

Seema Shah 《International Journal of Disability, Development & Education》2010,57(1):5-20

This article analyses the content and legal implementation of the right to education as a human right in Canada. It seeks to expose the extent to which Canadian legislative mechanisms have succeeded in protecting the right to education of students with disabilities by using students with epilepsy as a test case. To that end, the article examines the barriers faced by students with epilepsy in realising their right to education. It explores the content of the right to education in international law so as to provide an ideal against which the legal implementation of the right to education in Canada can be measured. In examining the degree to which legal implementation of the right to education for students with disabilities lives up to the ideals espoused in international law, the article analyses the effectiveness of the legal mechanisms that implement the right to education for students with epilepsy in addressing the three types of barriers faced by these students. The revelation of where students with epilepsy fall through the cracks serves as a reflection of the limits of current legal mechanisms in protecting the right to education for students with disabilities.  相似文献
