Teacher participation in the decision‐making process: reality and repercussions in Indian higher education     

Deepa Mehta  Alok Gardia  H.C.S. Rathore 《Compare》2010,40(5):659-671

The study reported here focused on comparing teachers’ actual and desired participation in different decision‐making situations and examined how participation in decision making differs in Indian higher educational institutions. The paper provides a comparison of findings with similar studies conducted in Western settings regarding the relationship of participative decision making (PDM) with some selected organizational variables: teachers’ job satisfaction, organizational goal commitment, role ambiguity, and role conflict. Data were gathered through a survey of 281 faculty members of Banaras Hindu University, India. Results indicate that in the Indian context, teachers’ actual and desired participation was highest in institutional decisions and lowest in technical decisions. Among the personal variables, age, designation, teaching experience and span of service in present institution were found to be significantly related with decisional participation of university teachers. It is recommended that administrators evolve a mechanism for inviting participation of teachers in different decisional domains, based on the findings of this study.  相似文献

Interpreting HbA1c in Presence of Deficiency Anemias     

Seema Bhargava  Khageshwar Mahato  Anjali Manocha  Mamta Kankra  Parul Singla  Anisha Sharma  Ashok Ahirwar  Vinod Gupta  Salamma Jose 《Indian journal of clinical biochemistry : IJCB》2021,36(3):360

HbA1c is used extensively for the diagnosis and management of diabetes mellitus. It constitutes 80% of glycated HbA1(Glycated haemoglobin(GHb)A), and depends upon blood glucose and RBC life span. RBC life span varies with anemia, leading to a consequent alteration in the HbA1c value irrespective of the circulating blood glucose concentration. But to the best of our knowledge no Hb cut offs have been derived for appropriate interpretation of HbA1c. The prevalence of anemia in Indian population is nearly 40% as per its definition by WHO—Hb < 12 g/dL in females and < 13 g/dL in males—with most cases attributable to nutritional deficiencies. Hence, we aimed to identify Hb cut-off for accurate interpretation of HbA_1c in presence of deficiency anemias. Partial correlation between random blood glucose (RBG) and HbA_1c was studied in 1312 subjects, 470 of whom had deficiency-related anemia]. The data was adjusted for age, sex and Hb. Partial correlation between RBG and HbA1c was highly significant (p < 0.0001) till Hb of 8.1 gm/dL. Significance reduced to p = 0.003 and p = 0.006 as the cut off of Hb reduced to 7.1 gm/dL and 5.0 gm/dL, respectively, but was not lost. Hence, caution in interpretation of HbA_1c is not required till an Hb of 5 g/dL.  相似文献   

A novel approach for part family formation using K-means algorithm     

Ashutosh Gupta  P.  K.  Jain Dinesh  Kumar 《上海大学学报(英文版)》2013,(3):241-250

The reconfigurable manufacturing system （RMS） is the next step in manufacturing, allowing the production of any quantity of highly customized and complex parts together with the benefits of mass production. In RMSs, parts are grouped into families, each of which requires a specific system configuration. Initially system is configured to produce the first family of parts. Once it is finished, the system will be reconfigured in order to produce the second family, and so forth. The effectiveness of a RMS depends on the formation of the optimum set of part families addressing various recon figurability issues. The aim of this work is to establish a methodology for grouping parts into families for effective working of RMS. The methodology carried out in two phases. In the first phase, the correlation matrix is used as similarity coefficient matrix. In the second phase, agglomerative hier archical Kmeans algorithm is used for the parts family for mation resulting in an optimum set of part families for reconfigurable manufacturing system.  相似文献

Eigentaste: A Constant Time Collaborative Filtering Algorithm   总被引：32，自引：2，他引：30  

Ken Goldberg  Theresa Roeder  Dhruv Gupta  Chris Perkins 《Information Retrieval》2001,4(2):133-151

Eigentaste is a collaborative filtering algorithm that uses universal queries to elicit real-valued user ratings on a common set of items and applies principal component analysis (PCA) to the resulting dense subset of the ratings matrix. PCA facilitates dimensionality reduction for offline clustering of users and rapid computation of recommendations. For a database of n users, standard nearest-neighbor techniques require O(n) processing time to compute recommendations, whereas Eigentaste requires O(1) (constant) time. We compare Eigentaste to alternative algorithms using data from Jester, an online joke recommending system.Jester has collected approximately 2,500,000 ratings from 57,000 users. We use the Normalized Mean Absolute Error (NMAE) measure to compare performance of different algorithms. In the Appendix we use Uniform and Normal distribution models to derive analytic estimates of NMAE when predictions are random. On the Jester dataset, Eigentaste computes recommendations two orders of magnitude faster with no loss of accuracy. Jester is online at: http://eigentaste.berkeley.edu  相似文献   

Scholarly Use of Web-based Information Resources and Services in University Libraries in Kerala (India)     

Deepa P. K. 《International Information and Library Review》2020,52(2):117-129

Abstract

Purpose: This study was conducted to investigate the use of web-based information services in university libraries in Kerala, India.

Design/methodology/approach: A survey method was used for the collection of data. The questionnaire method was used to collect data for the study. The study was conducted among the research scholars of four selected universities in Kerala, India.

Findings: This study has analyzed the services and resources in the libraries which are provided through the medium of the internet and also the usage patterns of web information services by the scholars of the selected universities. The analysis reveals that most of the university libraries have implemented web-based information services. However, the extent of usage is not to the expected level and this is due to the lack of sufficient awareness about the usage methods of web resources and services. With the help of proper user education and training programs, the present situation can be ameliorated. The findings of this study can be helpful to the authorities to improve the services in the libraries.

Originality/value: Proper use of library resources is essential for scholars to bring forth productive research outputs. This study provides recommendations for enhancing web-based services in university libraries in Kerala to provide better services to the users.  相似文献   

Prevalence of Vitamin D Deficiency in a Pediatric Hospital of Eastern India     

Surupa Basu  Ruchi Gupta  Monjori Mitra  Apurba Ghosh 《Indian journal of clinical biochemistry : IJCB》2015,30(2):167-173

Vitamin D deficiency is highly prevalent in Indian children of northern, western and southern states. Serum 25 hydroxy cholecalferol (ng/ml) was analyzed in 310 children and adolescents of pediatric hospital of Kolkata, India. Serum calcium (mg/dl), phosphorous (mg/dl) and alkaline phosphatase (IU/L) data was obtained. Median 25(OH)D was 19 ng/ml. 19.2 % of population had serum 25(OH)D < 10 ng/ml (severe deficiency), 52.9 % had <20 ng/ml (deficiency), 24.5 % had 20–29 ng/ml (insufficiency) and 22.6 % had >30 ng/ml (optimum). Deficiency was highest in adolescents (86.1 %), followed by school children (61.0 %), lowest in pre-school children (41.6 %). 25(OH)D concentrations was lowest in winters (P = 0.002) and spring (P = 0.03) compared to summer. There was no correlation with calcium (P = 0.99), phosphorous (P = 0.23) and ALP (P = 0.63). There is high prevalence of vitamin D deficiency in children and adolescents of eastern India. Prevalence was lower in younger subjects. 25(OH)D did not correlate with bone mineral markers.  相似文献
