The need to continuously evaluate resource usage, whether in print or online, has been a challenge for libraries for a long time. The shift in resources to digital formats has made gauging the utility of resources more convenient as well as enabling cross database comparisons on various parameters. In this context, the article explores the aggregator databases subscribed by Indian Institute of Management Ahmedabad library. The study compares EBSCO's Business Source Complete, EBSCO's Academic Search Premier, Proquest's ABI INFORM Complete, JSTOR, and Project Muse packages in terms of the features available, usage, and the most used journals in these packages. 相似文献

Abstract This paper examines new organizational arrangements that have emerged in the context of a privatized extension system. It investigates the positioning and embedding of a network broker aimed at enhancing interaction in the privatized agricultural knowledge and information system (AKIS), to assess whether tensions reported in other sectors also manifest in agriculture and inform theory and policy on collective functions in pluralistic extension systems. It employs a case study approach using semi-structured interviews, observations, a closed questionnaire and secondary data analysis. Results show that a demand-driven way of working may prevent network brokers losing their neutrality in farmers’ eyes, but that a network broker nevertheless can be perceived as disruptive by extension service providers. Furthermore, it appears hard to make the network brokerage function self-sufficient. The paper shows that a social dilemma manifests, that is, the collective benefits are recognized, but private interests do not support the brokers’ continued existence. This prompts consideration of the need for continued public support. Public support for network broker appears to be needed, but possible (market-disturbing) interference with the activities of private extension service providers prompts critical examination of the mandates of publicly funded network brokers. 相似文献

National educational standards (NES) were released in Germany 2003/2004 as obligatory performance standards substantively and normatively defining an acceptable degree of proficiency. The NES describe tangible competencies in the form of can-do statements for core subjects to be acquired by students at the end of defined stages of schooling. To evaluate standards-based performances the Standing Conference of the Ministers of Education and Cultural Affairs of the Federal States in Germany (KMK) implemented a test-based monitoring system that comprised a centralized evaluation in a nationwide study sample comparing the German federal states (Ländervergleich), as well as state-wide testing schemes at the end of grade 3 and grade 8 linked to the NES. All test items were designed by didactic experts on the basis of domain specific competence models that were psychometrically evaluated. The potential practical benefit from competence testing is discussed for the various system levels of feedback (state, school, teacher, and student). It is argued that, in order to tap the full potential of standards-based performance feedback, it must be appropriately communicated to the target system level and should be accompanied by suitable measures of action support. 相似文献

Study investigates the availability, persistence and half life of URL citations cited in two Indian LIS journals articles published between 2002 and 2010. This study also investigates how researchers can resurrect lapsed URL citations cited in research articles, using Wayback machine. A total of 1290 URLs cited in 472 research articles published in Indian LIS journals spanning a period of 9 years (2002–2010) were extracted. Study found that only 18.91% (1290 out of 6820) of URLs cited in these journal articles. 39.84% of URL citations were not accessible and remaining 60.15% of URL citations were still accessible. The HTTP 404 error message-“page not found” was the overwhelming message encountered and represented 54.86% of all HTTP error messages. However 51.06% URLs were recovered from HTTP 404 error message. Study also noticed that the half-life of URL citations was increased from 6.33 years to 13.85 years after recovering missing URLs from Wayback machine. 相似文献

Despite the rising implementation of RFID technology-based healthcare services, few empirical studies have been conducted to assess the potential of this technology within the healthcare sector. The purpose of this study is to help initiate and direct such empirical research by both conducting a review of the extant literature and using the findings to provide a discussion of current trends and future directions in this domain. In this paper, we develop a conceptual framework that can be used to classify publications on RFID applications and issues in the healthcare industry. We then use this framework to systematically summarize relevant articles. We conclude by highlighting future research directions where the deployment of RFID technology is likely to transform the healthcare sector. 相似文献

Helicobacter pylori infection stimulates strong local inflammatory and specific IgA antibody production. The influence of antibodies on the bacterial colonization is not clear. Here, we have analysed the association between the mucosal IgA level and IL-1β in various manifestations of the infection seen endoscopically. Antral biopsies of 57 dyspeptic patients were taken for culture, histology and estimation of mucosal levels of anti-H. pylori IgA and IL-1β. Mean mucosal IgA level was higher in patients with normal mucosa compared to all other groups and lower IgA level was associated with higher bacterial density. IL-1β was higher in ulcer patients and suspicious malignancy group as compared to normal group and higher level of IL-1β was associated with higher grades of metaplasia. Present study indicates that local immunity seems to have a protective role against H. pylori infection and higher level of IL-1β induced by the pathogen may be associated with metaplasia and carcinogenesis. 相似文献

The aim of this study was to assess the diagnostic yield of the tumour markers carcinoembryonic antigen, carbohydrate antigen 15-3, carbohydrate antigen 19-9 and carbohydrate antigen 125, in serum and bronchoalveolar lavage fluid in a group of patients with bronchogenic carcinoma. Serum and bronchoalveolar lavage fluid samples were collected in a group of 90 patients with benign or malignant pulmonary diseases. After appropriate processing, tumour markers were determined by enzyme immunoassay. The diagnostic yields (sensitivity, specificity and predictive values) in each environment (serum and bronchoalveolar lavage fluid) were obtained by using "Receivers operating characteristic" curve. Determined individually, carcinoembryonic antigen, carbohydrate antigen 19-9 and carbohydrate antigen 125, showed the greatest diagnostic accuracy in bronchoalveolar lavage fluid. Carbohydrate antigen 15-3 did so in serum. Carcinoembryonic antigen was the most relevant marker in bronchoalveolar lavage fluid. For the factors evaluated in this study, determination of carcinoembryonic antigen, carbohydrate antigen 19-9 and carbohydrate antigen 125 in bronchoalveolar lavage fluid were clinically more useful markers in comparison with serum, although the latter may also be helpful in certain situations. Although there is no specific tumour marker for lung cancer, the combination of several can be used to diagnose most patients with lung cancer and also to rule out false positive and negative cases. 相似文献

A 3 month old male child was brought to the hospital with complaints of skin rashes, developmental delay, seizures, seborrheic
dermatitis, alopecia and mild, acidosis. The child was subjected to a simple metabolic screening protocol. The result of the
screening and the clinical symptoms provided an index pointing towards biotinidase deficiency., a rare autosomal recessive,
inherited metabolic disorder. The enzyme was then assayed by using n-biotinylp-aminobenzoate as substrate and the diagnosis confirmed. A follow-up of the case indicated the efficacy, of biotin supplementation
in biotinidase deficiency. 相似文献

Masking the bitter taste of drugs is a potential tool for the improvement of patient compliance, which in turn decides the
commercial success of the product. To improve the palatability of a pharmaceutical product, many techniques have been developed,
which have not only improved the taste of the product, but also the stability of the drug in the formulation and performance
of the product. This article is an attempt to review strategies, technologies and tools that are used by pharmaceutical scientists
for taste-masking. 相似文献

Studies were conducted under pot conditions to determine the comparative efficacy of carbofuran at 1 mg a.i./kg soil, bavistin
at 1 mg a.i./kg soil, neem (Azadirachta indica) seed powder at 50 mg/kg soil, green mould (Trichoderma harzianum) at 50.0 ml/kg soil, rhizobacteria (Pseudomonas fluorescens) at 50.0 ml/kg soil against root-knot nematode,Meloidogyne incognita-wilt fungus,Fusarium oxysporum disease complex on green gram,Vigna radiata cv ML-1108. All the treatments significantly improved the growth of the plants as compared to untreated inoculated plants.
Analysis of data showed that carbofuran andA. indica seed powder increased plant growth and yield significantly more in comparison to bavistin andP. fluorescens. Carbofuran was highly effective against nematode, bavistin against fungus,A. indica seed powder against both the pathogens and both the bioagents were moderately effective against both the pathogens. 相似文献
