An analysis of professional practice Ed.D. dissertations in Educational Technology     

Kara Dawson  Swapna Kumar 《TechTrends》2014,58(4):62-72

The University of Florida offers an online professional practice Ed.D. focused on Educational Technology. Twenty-three students have completed professional practice dissertations and graduated since the program’s inception in 2008. The purpose of this article is to share what these dissertations have looked like and to begin a dialogue about professional practice dissertations completed in online educational technology programs. Specifically, we (1) provide an overview of different ways professional practice Ed.D. dissertations are structured, (2) share guiding principles for professional practice dissertations in our Ed.D. program, (3) analyze the ways in which these guiding principles played out in the dissertations and (4) discuss the implications of our analysis for our program and for other online professional practice programs in Educational Technology.  相似文献

An Overview of Modern Technologies Applications in Indian Libraries (Brief Communication)     

R. P. Kumar 《International Information and Library Review》1994,26(4)

India is one of the oldest civilizations with a kaleidoscopic variety and rich cultural heritage. It has achieved multi-faccted socio-economic progress during the last 47 years of its independence. This article reports on a survey of the usage of modern technologies (e.g. photocopiers, microfilming, computers, facsimile transmission, audio-visual, online searching and CD-ROMs) in Indian libraries. These libraries include university, engineering, scientific, medical, government and public libraries. The study used a questionnaire, personal visits to many libraries and interviews. The paper examines the impact of modern technologies on these libraries. It concludes with a summary of the problems faced by the librarians in adopting the modern technologies and suggests measures for implementation of modern technologies.  相似文献

Dynamic optimal control model for profit maximization of software product under the influence of promotional effort     

P.K. Kapur  Hoang Pham  Vijay Kumar  Adarsh Anand 《The Journal of High Technology Management Research》2012,23(2):122-129

In this paper, a decision model is presented for the sales of software product to determine the profit and marketing policy under the influence of promotional efforts. The paper focuses on dependence of the optimal profit on the promotional efforts when there is diffusion effect of demand on the sales function. An elaborate optimization policy considering the dynamic nature of production cost function is proposed and numerical example is illustrated. The paper also studies the behavior of the future profit and its impact on profit maximization model by considering the constant price during the entire planning horizon. The experimental results greatly help us to identify the contributions of each selected parameter and its weight. Some conclusions, limitations of this study and future direction are also discussed.  相似文献   

Angiotensin Converting Enzyme Gene Polymorphism and its Association with Hypertension in South Indian Population     

Ipsita Choudhury  R. Jothimalar  Arun Kumar Patra 《Indian journal of clinical biochemistry : IJCB》2012,27(3):265-269

Hypertension, a well known risk factor for various cardiovascular, peripheral vascular and renal events is an important public health challenge. Renin angiotensin system (RAS) being the most vital pathogenic mechanism of hypertension is mediated by a key component; the angiotensin converting enzyme (ACE). The present study was aimed to know the relationship of ACE gene polymorphism and the possible risk of development of hypertension in south Indian population. The study included 101 clinically diagnosed hypertensive patients without any associated disease condition and 81 age and sex matched apparently healthy controls. Genotyping was performed using a polymerase chain reaction, (PCR) amplification of the intron 16 fragment harboring the 287 bp Alu repeat sequence. Three possible genotypes D/D, I/I homozygous and I/D heterozygous were analyzed where the D/D genotypes corresponds to higher ACE levels (D-Deletion, I-Insertion). The PCR products were separated on 2 % agarose gel. Statistical analysis was performed using SPSS.15 software program. We found a significance in frequency of D/D genotype in the hypertensive patients compared to the control group (p = 0.0005, odd’s ratio = 4.157). This suggested that ACE (D/D) genotypes are more prone for the development of hypertension. This is relatively a pilot study; but nevertheless may assist in identifying the pathophysiological cause of hypertension.  相似文献   

Collection development and access to serials in the Central Library of IITs in India     

Tapas Kumar Ghosh  K.C. Panda 《Library Collections, Acquisitions, and Technical Services》2010,34(2-3):45-50

The vital task of the libraries attached to the educational institutions of higher learning is the collection development of information resources as per the requirements of the users. The Central Library of IITs have long been recognized their responsibility to support the study and research of their parent institutions with the rich collection development of information resources both in print as well as electronic format to cater the needs of the academic communities as per the multi-disciplinary and diverse academic program of the respective institutions where greater emphasis on collection of serials, the essential and integral component of updated scholarly communication. The study provides a vivid picture about the current status of serials collection in the libraries attached to the Premier Institutions of India in the field of science and technology to boost up the academic performances.  相似文献

Assessment of Adoption Gaps in Management of Aflatoxin Contamination of Groundnut (Arachis Hypogaea L.)     

G.D.S. Kumar  M.N. Popat 《The Journal of Agricultural Education and Extension》2013,19(3):309-319

Abstract

One of the major impediments for diversification of groundnut (Arachis Hypogaea L.) as food crop is aflatoxin contamination. The study was conducted with an objective to assess the adoption gaps in aflatoxin management practices of groundnut (AMPG) and the farmer's characteristics influencing these gaps. The study used an expost-facto research design and multi-stage random sampling. The data were collected from 180 respondents through interview schedule. For measuring adoption gap, knowledge of AMPG and perception of groundnut quality suitable scales were developed. The data were subjected to multiple regression analysis to know the characteristics, which influenced the adoption gaps in AMPG. The majority of farmers were in high adoption gap category, as most of the farmers had not adopted the harvest and post-harvest management practices. Farmers' characteristics such as knowledge, market orientation and innovativeness influenced the adoption gap significantly. These three variables put together explained 58% of variation in adoption gap. Based on the results, it is suggested to formulate strategies to increase the knowledge of farmers through various extension approaches. If the knowledge on AMPG is improved the adoption gaps can be reduced. The maiden research effort, shed light on the socio-economic dimensions of aflatoxin contamination and constraints for aflatoxin management at farmers' level. The study has significance for the policy makers, extension departments and groundnut farmers for production of quality groundnut.  相似文献
