An institutional repository is a system for dissemination and stewardship of the intellectual life and scholarship of an institution. It has become a new way for the institutions to contribute to the broader world of scholarship (Giesecke, 2011). In spite of the global recognition of institutional repositories as an open access scholarly communication channel, institutional repositories are still struggling with the problem of non-participation from contributors in developing countries like India. This study conveys the results of a survey conducted at a minority university of India. The study is an expression of the opinion of 542 faculty members and research scholars pertaining to the possible implications of institutional repositories on their professional and publishing practices. The study is undertaken to: Determine the level of awareness of institutional repository among contributors; identify the reasons for participation and non-participation of contributors; examine the implications of institutional repository on contributors professional and publishing practices; analyze the major obstacles/hindrances in the growth of an institutional repository; and suggest measures for better implementation and development of an institutional repository in future. With the help of the statistical techniques such as chi-square test and weighted mean the study resulted that the majority of the contributors are well aware about the concept of institutional repository, the majority of contributors have not deposited in an institutional repository so far, long term preservation of research materials is the first ranked reason for participation in an institutional repository, copyright and plagiarism concern is the main reason behind contributors’ non-participation in institutional repository, increased accessibility of research output is the major implication of the institutional repository on contributors professional practices, saved cost of publishing in a journal is the biggest implication of institutional repository on contributors publishing practices, and contributors demand more control on ownership, access and security in future for an institutional repository. This article is aimed at the institutions that report low-use and low-deposit repositories. It may be used to convince the contributors about the value of institutional repositories, importance of participating in an institutional repository and possible implications on their professional and publishing practices. The study is also intended at the management of the institutions to take notice of the contributors’ demands for future participation and develop policies accordingly for removing major barriers in the growth of institutional repositories and improving contributions and quality of content in the institutional repositories. 相似文献

The U.S. government has become increasingly focused on school climate, as recently evidenced by its inclusion as an accountability indicator in the Every Student Succeeds Act. Yet, there remains considerable variability in both conceptualizing and measuring school climate. To better inform the research and practice related to school climate and its measurement, we leveraged item response theory (IRT), a commonly used psychometric approach for the design of achievement assessments, to create a parsimonious measure of school climate that operates across varying individual characteristics. Students (n = 69,513) in 111 secondary schools completed a school climate assessment focused on three domains of climate (i.e., safety, engagement, and environment), as defined by the U.S. Department of Education. Item and test characteristics were estimated using the mirt package in R using unidimensional IRT. Analyses revealed measurement difficulties that resulted in a greater ability to assess less favorable perspectives on school climate. Differential item functioning analyses indicated measurement differences based on student academic success. These findings support the development of a broad measure of school climate but also highlight the importance of work to ensure precision in measuring school climate, particularly when considering use as an accountability measure. 相似文献

In the present study the antioxidative potential ofMomordica charantia, Azadirachta indica, Allium sativum andOcimum sanctum was assessed in streptozotocin induced diabetic rats. Lipid peroxide levels were also measured in normal, diabetic and treated
animals. Malondialdehyde (MDA) levels were significantly higher and antioxidant activity was found low in diabetic groups
as compared to the control groups, and significant alteration in both the MDA levels and antioxidant activity was also observed
when the above herbal hypoglycemic agents were given to diabetic rats. On the basis of our results we conclude thatM. charantia, A. indica, A. sativum andO. sanctum are not only useful in controlling the lipid peroxide levels but are also helpful in further strengthening the antioxidant
potential. 相似文献

Burnout is a concept which was born in the mid 1970’s in the USA and with astonishing rapidity has become a catch-word to
convey an almost unlimited variety of social and personal problems afflicting workers. It describes a specific dysfunction
among helping professionals, believed to be the result of excessive demands made upon their energy, strength and resources.
Although a clearly agreed upon definition does not exist, burnout is characterized by the inability to be sufficiently concerned
about and involved with service recipients. A burnt out worker tends to withdraw emotionally from the demands of the job.
Burnout is reflected in emotional exhaustion and apathy, physical fatigue, lack of energy, psychosomatic illness, increased
alcohol and drug consumption, cynicism, inappropriate anger, depression and lack of personal achievements. Now, it is observed
that teachers are also showing symptoms of burnout, which directly or indirectly affect their teaching performance. Motivated
by these reasons the investigators decided to investigate the status of burnout among secondary school teachers and assess
its extent in Indian teachers. 相似文献

Sustained high levels of circulating catecholamines are reported to induce cardiotoxicity. Isoproterenol (ISP), a synthetic catecholamine has been widely employed to induce myocardial injury, though the role of inflammation and apoptosis is not well established. This study was designed to investigate the underlying mechanism of oxidative damage, inflammatory signaling, cell death in ISP induced myocardial infarction in rats. Wistar albino rats were divided in two groups: group I (sham control) and group II (ischemic control). ISP (85 mg/kg, s.c.) was administered at an interval of 24 h to group II for two consecutive days. On day third, after 48 h of the first injection of ISP, blood was collected from retro orbital plexus of rat eyes to estimate the biochemical parameters. Glutathione (GSH) and superoxide dismutase (SOD) were measured for antioxidant status. Similarly, malondialdehyde (MDA) was measured as an index of lipid peroxidation. Cardiac markers (SGOT, CK-MB, TropI and LDH) and pro-inflammatory cytokines (IL-6, CRP and TNF-α) were also estimated in ISP-induced rats. At the end of experiments animals were sacrificed for histopathological studies. GSH and SOD showed significant decrease after ISP challenge as compared to sham (control) group (p < 0.01) while MDA level, increased significantly (p < 0.01). ISP, also increased the level of cardiac markers and markers of inflammation significantly (p < 0.01), which was further verified by histopathological studies of the heart tissues. The study confirmed that ISP causes detrimental changes in the myocardium by altering cardiac and inflammatory markers, which leads to severe necrosis. The deleterious effects produced by ISP substantiate its suitability as a novel animal model for evaluation of cardioprotective agents/drugs. 相似文献

Cholesterol and phospholipids were estimated in serum and bile from hepatic duct and gallbladder of twenty five patients of gallstone with functioning gallbladder (Group-I) and an equal number of patients having diseases other than of hepatobiliary system acting as control (Group-II). Group-I patients showed high serum cholesterol and low serum phospholipid levels as compared to those of Group-II. Cholesterol levels in hepatic duct and gallbladder bile were higher in Group-I than in Group-II whereas the phospholipid levels in the bile of Group-I were lower than in Group-II. The phospholipid: cholesterol ratios in hepatic duct and gallbladder bile of Group-I were 2.76 and 3.03 respectively as compared to 5.62 and 5.92 in Group-II. 相似文献
