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   

Virtual education in universities: a technological imperative   总被引：1，自引：0，他引：1  

John O'Donoghue  Gurmak Singh  & Lisa Dorward 《British journal of educational technology : journal of the Council for Educational Technology》2001,32(5):511-523

Many educational journals have debated the issue of the "virtual university". As technology is improving and evolving, such "virtuality" becomes a reality. The forecasts are that, in the not too distant future, it will be possible for courses to be completed solely by the use of the World Wide Web or Internet. These "virtual classrooms" will take the place of the solid buildings where students currently attend lectures, at set times in set rooms. The information will be gathered at the student's convenience and assignments will be handed in via this medium. There is potentially an advantage for everyone involved, from the reduced building resource costs to the availability of teaching support 24 hours a day, 7 days a week
Whilst many of these studies identify the benefits of technology in education there are dissenting voices from many other quarters. However there are also arguments identifying the disadvantages to the technology based delivery systems proposed. Either way, there are going to be radical changes in the methods which students will use to tackle the workload involved in studying towards a degree. This paper will explore both sides of the argument. The main contention of this paper is that technology undoubtedly will offer many benefits for the learner, however, the pitfalls need careful consideration in the design of the learning environment. This paper uses examples from educational institutions across different cultures.  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
