Finding a plausible option for revitalising agricultural higher education in India: a systematic review     

Niraj Kumar 《Journal of Higher Education Policy & Management》2016,38(6):676-689

The objectives of this paper were to explore the existing status of agricultural higher education in India, application of marketing concepts in similar institutions and to find the most appropriate marketing concept to make agricultural higher education more competitive. Extensive searches of relevant agricultural education, business management and higher educational data bases were made. It was found that agricultural higher education in India is stagnant and is facing an identity crisis among its stakeholders. Marketing theories and concepts which are now being applied in higher education across the globe have not been thought of in the context of agriculture education. A review of the literature suggested that considering the objectives, the multiplicity of stakeholders and the nature of public-funded agricultural education, marketing orientation would be most appropriate. Based on the experiences of similar institutions, the paper suggests a three-level strategy for the implementation of marketing orientation in institutions of agricultural higher education.  相似文献   

Joint routing and rate allocation for multiple video streams in ad-hoc wireless networks     

SINGH Jatinder Pal  GIROD Bernd 《浙江大学学报(A卷英文版)》2006,7(5):727-736

INTRODUCTION Ad-hoc networks are attractive owing to their self-organizing nature and absence of a fixed infra- structure. They are particularly suited for communi- cation in disaster-affected areas, coordinating military operations, and sensing environmental conditions With the growing availability of supporting hardware and decreasing equipment cost, ad-hoc networking based applications are proliferating. Meshes of wire- less nodes are being deployed in cities and housing communities to…  相似文献   

Students’ experiences of home–school dissonance: The role of school academic culture and perceptions of classroom goal structures     

Revathy Kumar 《Contemporary educational psychology》2006

This paper examines stability and change during the elementary-to-middle school transition, focusing on adolescents’ experiences of home–school dissonance because of real or perceived differences between home/self and values within the school context. Relationships were hypothesized between exacerbation and amelioration of dissonance, middle school mastery and performance goal practices, and students’ perceptions thereof. The sample consisted of 274 African-American and 284 European-American (49% female) students. Middle school teachers (N = 236) provided data on school academic practices. Multilevel growth curve analysis indicated significant variance among the 10 middle schools regarding change in dissonance. Both mastery-focused middle school practices and students’ perception of middle school classrooms as more performance and less mastery focused than elementary classrooms were significant predictors of change in dissonance. Path-analyses evidence pointed to the mediational role of school belonging on the relationship between perception of classroom mastery goals and dissonance. Path analyses revealed direct and indirect effects of perception of classroom performance goals on dissonance and school belonging. This paper highlights the importance of creating inclusive learning environments that minimize social comparison saliency and validate students for who they are.  相似文献   

DNA combing on low-pressure oxygen plasma modified polysilsesquioxane substrates for single-molecule studies     

K. K. Sriram  Chun-Ling Chang  U. Rajesh Kumar  Chia-Fu Chou 《Biomicrofluidics》2014,8(5)

Molecular combing and flow-induced stretching are the most commonly used methods to immobilize and stretch DNA molecules. While both approaches require functionalization steps for the substrate surface and the molecules, conventionally the former does not take advantage of, as the latter, the versatility of microfluidics regarding robustness, buffer exchange capability, and molecule manipulation using external forces for single molecule studies. Here, we demonstrate a simple one-step combing process involving only low-pressure oxygen (O₂) plasma modified polysilsesquioxane (PSQ) polymer layer to facilitate both room temperature microfluidic device bonding and immobilization of stretched single DNA molecules without molecular functionalization step. Atomic force microscopy and Kelvin probe force microscopy experiments revealed a significant increase in surface roughness and surface potential on low-pressure O₂ plasma treated PSQ, in contrast to that with high-pressure O₂ plasma treatment, which are proposed to be responsible for enabling effective DNA immobilization. We further demonstrate the use of our platform to observe DNA-RNA polymerase complexes and cancer drug cisplatin induced DNA condensation using wide-field fluorescence imaging.  相似文献   

How Much of Library and Information Science Literature Qualifies as Research?     

Mirna E. Turcios  Naresh Kumar Agarwal  Linda Watkins 《The Journal of Academic Librarianship》2014,40(5):473-479

There is an extensive amount of Library and Information Science (LIS) writing produced each year. While there is general awareness regarding the variety of journal literature, there is no certainty on the percentage of the collection that we can call research. This project is an important first step in answering the question. A content analysis of the LIS academic/scholarly journals at the Simmons College Library was conducted. The research level collection of LIS literature makes the library an ideal candidate for this study. The latest issue of each journal subscribed to for fiscal year 2012–2013 containing academic/scholarly content was analyzed. Each article was analyzed to determine: 1) if it was research or non-research, 2) the method used to collect data for the study in the article, and 3) the subject terms or keywords associated with the article. 105 journal titles were identified out of 177 periodicals. In the 1880 articles analyzed from these, 16% qualified as research. Surveys were found to be the most popular research method used. This study will benefit students, faculty, and staff with research requirements as well as librarians who guide patrons through a search for research literature.  相似文献

Decay and half-life period of online citations cited in open access journals     

B.T. Sampath Kumar  K.S. Manoj Kumar 《International Information and Library Review》2012,44(4):202-211

This study investigates the decay and half-life of online citations cited in four open access journals published between 2000 and 2009. A total of 1158 online citations cited in 1086 research articles published in two science and social science journals spanning a period of 10 years (2000–2009) were extracted. Study found that 24.58% (267 out of 1086) of articles had online citations and these articles contained a substantially very less number of online citations (2.98%) compared to previous study results. 30.56% (26% in Science and 52.73% in Social Science) of online citations were not accessible and remaining 69.44% of online citations were still accessible. The ‘HTTP 404 error message-page not found’ was the overwhelming message encountered and represented 67.79% of all HTTP message. Domains associated with .ac and .net had higher successful access rates while .org and .com/.co had lowest successful access rates. The half-life of online citations was computed to be approximately 11.5 years and 9.07 years in Science and Social science journal articles respectively.  相似文献   

The effects of passive and active learning on student preference and performance in an undergraduate basic science course     

Minhas PS  Ghosh A  Swanzy L 《Anatomical sciences education》2012,5(4):200-207

Active learning is based on self-directed and autonomous teaching methods, whereas passive learning is grounded in instructor taught lectures. An animal physiology course was studied over a two-year period (Year 1, n = 42 students; Year 2, n = 30 students) to determine the effects of student-led seminar (andragogical) and lecture (pedagogical) teaching methods on students' retention of information and performance. For each year of the study, the course was divided into two time periods. The first half was dedicated to instructor-led lectures, followed by a control survey in which the students rated the efficiency of pedagogical learning on a five-point Likert scale from one (strongly disagree) to five (strongly agree). During the second period, students engaged in andragogical learning via peer-led seminars. An experimental survey was then administered to students using the same scale as above to determine students' preferred teaching method. Raw examination scores and survey results from both halves of the course were statistically analyzed by ANOVA with Newman-Keuls multiple comparison test. By the end of the study, student preference for peer-led seminars increased [mean ± SD: (2.47 ± 0.94)/(4.03 ± 1.36), P < 0.04], and examination scores significantly increased [mean ± SD: (73.91% ± 13.18)/(85.77 ± 5.22), P < 0.001]. A majority of students (68.8%) preferred a method that contained peer-led seminars and instructor-led lectures. These results may indicate that integration of active and passive learning into undergraduate courses may have greater benefit in terms of student preference and performance than either method alone.  相似文献
