Usage of E-journals by researchers in Aligarh Muslim University     

M. Masoom Raza  Ashok Kumar Upadhyay 《International Information and Library Review》2013,45(3):170-179

Abstract

This article presents a study that seeks to examine the usage of e-journals by the researchers at Aligarh Muslim University. The survey reveals that all the researchers are aware of e-journals in AMU. From this survey, the investigator has been able to find out that many research scholars are consulting e-journals from their departmental labs and computer centers, not only for research purposes but also to update their own knowledge. However, the study also revealed several problems, including lack of training and slow downloading. The researchers’ feelings about the need for print journals as well as electronic journals are also discussed.  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》2013,45(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   

A Quantitative Analysis of Research Output of Jawaharlal Nehru University,New Delhi,India     

Manorama Tripathi  Sunil Kumar 《International Information and Library Review》2013,45(1-2):39-51

This study provides an overview of the research output of Jawaharlal Nehru University, New Delhi, India, in terms of number of publications contributed by faculty members and researchers. The study analyzes bibliometric indicators of published research of Jawaharlal Nehru University as indexed in the Web of Science. There were 5,007 research publications from Jawaharlal Nehru University in the four decades from 1971–2010 (70s; 80s; 90s; and 2000s). The study noted encouraging trends in collaborative research work with multiple-authored research papers. International collaboration in research was also observed among the faculty members and researchers. English was the predominant language of communication. The social scientists and humanists of Jawaharlal Nehru University publish books which are not indexed in the Web of Science. Similarly, research work published in regional languages or published in national level journals are seldom included in the Web of Science. It suggests that research needs to be done by collecting data from the Indian Citation Index and books published by the researchers in order to get an accurate and consolidated picture of the research output of the university.  相似文献   

Transparency,accountability and good governance: Role of new information and communication technologies and the mass media     

Shahid Akhtar  Mahesh Kumar Malla  John Gregson 《媒体管理杂志》2013,15(3-4):124-132

Abstract

Customer orientation has been suggested to create competitive advantage of firms (Kohli &; Jaworski, 1990 Kohli, A. K. and Jaworski, B. J. 1990. Market orientation: The construct, research propositions, and managerial implications. Journal of Marketing, 54(2): 1–18. [Crossref], [Web of Science ®] , [Google Scholar]). Therefore, the recommendation to media managers has been to let the creation and delivery of customer value guide their strategies for advertising sales (Aris &; Bughin, 2005 Aris, A. and Bughin, J. 2005. Managing media companies: Harnessing creative value, Chichester, , England: Wiley.  [Google Scholar]). However, the concept of customer value, what it is, and how it is created remains unclear in many ways. This article explores the concept of customer value in advertising media purchasing from the media seller's perspective. Between December 2007 and February 2008, sales representatives from three Swedish TV networks were studied through in-depth interviews and observations as they progressed through a negotiation process with a large advertiser and its media agency. A qualitative analysis of the media sellers' experiences shows that they see advertiser and agency to perceiving the value of advertising media differently. Also, they see the customer side parties as diverging in the processes by which these value perceptions are formed. The article reveals the inherent problem of customer orientation on advertising markets—that within media purchasing practice, several actors have their own idea of value, and an advertiser's understanding of value is not always a decisive factor. The TV networks in the study have all chosen different strategies to deal with these dualities.  相似文献   

Circadian rhythms     

Koustubh M. Vaze  Vijay Kumar Sharma 《Resonance》2013,18(7):662-672

Living organisms ranging from bacteria to human beings exhibit 24-h rhythms in various behaviours and physiological processes. Matching of the period of such rhythms with that of the daily environmental cycles gives an impression that they are mere passive responses to environmental changes. Here, we discuss the change in our perception about daily biological rhythms, from their identity as rhythmic phenomena occurring as passive response to environmental changes, to the biological clocks. This is the first article in a series of articles on circadian rhythms which will cover discussion on the genetic and molecular basis, circadian organization and its adaptive significance.  相似文献   

A serpentine way to signaling     

Vignesh Narayan Hariharan  Raji R. Nair  Deepak Kumar Saini 《Resonance》2013,18(6):530-542

The Nobel Prize in Chemistry, 2012 has been awarded to Robert J Lefkowitz and Brian K Kobilka for their studies on G-Protein Coupled Receptors (GPCRs). GPCRs are receptor proteins present on the cell surface, which are involved in sensing molecules outside the cell and initiating a cellular response. They can sense a wide variety of ligands ranging from light to hormones and small peptides, triggering various physiological responses. Today we understand the molecular mechanisms by which these receptors work largely due to the contributions of Lefkowitz and Kobilka. Owing to the role of GPCRs in cell communication and involvement in various disease conditions, they are targets of over 40% of current drugs in the market. These findings have not only revealed how GPCRs work, but have also made a huge impact on the field of GPCR-associated drug discovery.  相似文献   

From inactivity to encouragement: the contribution of Lord Elphinstone to the educational development of the Madras Presidency (1837–1842)     

Gautam Chandra  Veerendra Kumar Mishra   《History of education》2013,42(6):763-778

In light of the focus placed on English education by the colonial government, and the petition signed by 70,000 local inhabitants of the Madras Presidency, Lord John Elphinstone, the Governor, made efforts to disseminate English education during his governorship (1837–1842). Spurred on by the petition, Elphinstone wrote two fundamental educational minutes, in 1839 and 1841, and established Madras High School. Later, the School was transformed into Presidency College and became the first home of the University of Madras. Elphinstone’s planning led to the first systematic effort by the Madras government to impart English education. Subsequently, Elphinstone emphasised the dissemination of secular education and inclusion of native people in educational administration. Against this background, this paper discusses the contribution of Elphinstone to the educational development of Madras. It also questions the historiographical neglect of Elphinstone and challenges the established post-colonial discourse that the establishment of English institutions was a ‘colonialist’ imposition.  相似文献   

Capacity building of a district education system: insights from Kenya     

Dipankar Datta  Serene Phillip  Prashant Kumar Verma 《Education 3-13》2013,41(3):203-217

Both (a) in-school factors such as over-focus on academic performance, absence of uniform, and corporal punishment, and (b) out-of school factors such as caring for ailing parents, child labour, etc., hinder participation of orphan and vulnerable children (OVC) in Free Primary Education (FPE) system in Nyanza Province, Kenya. In this context Concern Worldwide Kenya undertook an appreciative capacity building approach and appropriately positioned District Education Office (DEO) of the Ministry of Education and local civil society organisations (CSOs) to address in-school and out-of-school factors, respectively, to ensure quality education for OVC. The outcome of the programme is promising and has demonstrated the need for greater cooperation between CSOs and the government to develop creative strategies in overcoming the causes of marginalisation within the contexts of the growing AIDS pandemic and poverty in Kenya.  相似文献   

Effects of chronic ethanol consumption in blood: A time dependent study on rat     

Subir Kumar Das  L. Dhanya  Sowmya Varadhan  Sukhes Mukherjee  D. M. Vasudevan 《Indian journal of clinical biochemistry : IJCB》2009,24(3):301-306

Alcohol consumption and health outcomes are complex and multidimensional. Ethanol (1.6g / kg body weight/ day) exposure initially affects liver function followed by renal function of 16–18 week-old male albino rats of Wistar strain weighing 200–220 g. Chronic ethanol ingestion increased in thiobarbituric acid reactive substances level and glutathione s-transferase activity; while decreased reduced gluatathione content and activities of catalase, glutathione peroxidase and glutathione reductase in a time dependent manner in the hemolysate. Though superoxide dismutase activity increased initially might be due to adaptive response, but decreased later. Elevation of serum nitrite level and transforming growth factor-b₁ activity indicated that long-term ethanol consumption may cause hepatic fibrosis and can elicit pro-angiogenic factors. However, no alteration in vascular endothelial growth factor-C activity indicated that ethanol consumption is not associated with lymphangiogenesis. Therefore, we conclude that long-term ethanol-induced toxicity is linked to an oxidative stress, which may aggravate to fibrosis and elevate pro-angiogenic factors, but not associated with lymphangiogenesis.  相似文献
