OPEN ACCESS PUBLISHING MODEL: PREFERENCES, OPPORTUNITIES, AND CHALLENGES – AN OPINION SURVEY AMONG TEACHING STAFF IN HIGHER EDUCATION INSTITUTIONS IN TAMILNADU

Background: Open Access, a novel model of publishing is one among the surprises and delights of the digital age. It is a paradigm shift in the academic society which hammered up the traditional publishing and unlatched the doors of knowledge to reader community. One of the main drives of open access is to make academic research more easily available and maximum exploitation of resources. Objectives: This study aims to elucidate how well that teaching community working in higher education institutions in Tamil Nadu, endorses for the open access publishing model. The study elucidates their preferences on open access publishing and their perceptions about the opportunities and threats in open access publishing. Methods: Survey design was used to conduct the study and a structured questionnaire is used to collect data. Convenience sampling method is adopted for the study. Data collected were organized in Excel and analyzed by using SPSS PASW 18. Cronbach’s alpha is used to check the internal reliability of the opportunity and threats items. Frequencies and percentages were used to identify the popular publishing model, opportunity and threat. ANOVA and t-test were used to check the statistical relationship between variables. Results: A total of 121 teaching staffs from five higher education institutions in Tamil Nadu were enrolled in the study. Majority of the prefer Open Access publishing model over the other commercial and hybrid publication models. Around 66.1% of teaching staff responded that Open Access is their first choice of publishing. Around 45.5% of teaching staff abide if their subscribed commercial access publisher moves to hybrid access at some point. 51.2% of teaching abide if their subscribed commercial access publisher moves to complete open access at some point. The top most opportunity item as denoted by the teaching staff was New database of information are emerging and in development (71.1%). The top three threat items as denoted by the teaching staff was Open Access is still evolving to become sustainable (66.1%). Opportunity has a significant statistical relationship with No. of OA Journals publications. Conclusion: The study results will help the institutions, higher education system, librarians, information service providers, open access publishers & policy makers and government to intensify their efforts in promoting and nurturing open access publishing model

Automated Modeling of Real-Time Anomaly Detection using Non-Parametric Statistical technique for Data Streams in Cloud Environments

The main objective of online anomaly detection is to identify abnormal/unusual behavior such as network intrusions, malware infections, over utilized system resources due to design defects etc from real time data stream. Terrabytes of performance data generated in cloud data centers is a well accepted example of such data stream in real time. In this paper, we propose an online anomaly detection framework using non-parametric statistical technique in cloud data center. In order to determine the accuracy of the proposed work, we experiments it to data collected from RUBis cloud testbed and Yahoo Cloud Serving Benchmark (YCSB). Our experimental results shows the greater accuracy in terms of True Positive Rate (TPR), False Positive Rate (FPR), True Negative Rate (TNR) and False Negative Rate (FNR)

Orofacial granulomatosis: a rare case report with review of literature

The term orofacial granulomatosis (OFG) is a descriptive term used for granulomatous disorders affecting the face and oral cavity, which can occur for a variety of reasons resulting in significant morbidity. It is characterised by persistent swelling that may involve one or both the lips and /or recurrent ulcers and a variety of other orofacial features. Medical history is very important in the diagnosis of OFG as medical condition like Crohn’s disease can also present an extra intestinal manifestation of OFG. Exclusion of other entities like sarcoidosis, mycobacterial infections, foreign body reactions and biopsy helps to establish a correct diagnosis. Herein we report a case of OFG in a 55 year old female patient with review of literature

Successful management of severe acute respiratory distress syndrome caused by H1N1 viral pneumonia using early institution of extra corporeal membrane oxygenation therapy

Swine flu is H1N1 influenza A virus infection that has serious consequences in susceptible individuals leading to acute respiratory distress syndrome (ARDS). Sometimes ARDS can be refractory to conventional management and ventilator strategies. In such patients Extracorporeal Membrane Oxygenation (ECMO) improves respiratory functions wherein the gas exchange is done via a membrane oxygenator and a pump. We report a case of 50 years old female presented in February 2016 with complaints of fever, headache, dry cough, rhinorrhea and difficulty in breathing for four days. Her throat swab showed positive report for H1N1 infection. She developed severe ARDS due to pneumonia caused by H1N1 influenza infection. Her paO2/FiO2 was less than 100. The patient did not respond to initial management with anti- influenza therapy and mechanical ventilation. Murray score was calculated to institute ECMO therapy. Murray score of our patient was 2.75. Since there was no co- morbid illness or irreversible lung disease, ECMO therapy was started. After 14 days of ECMO therapy, ARDS resolved and the patient was successfully weaned from the ventilator. Patient was monitored intensively for coagulopathies and other complications related to ECMO therapy. She developed hemothorax and critical illness neuropathy during ECMO therapy. ECMO is a salvage therapy that has the potential to save lives when conventional treatment fails in H1N1 associated ARDS. It not only ensures much needed lung protection to the inflamed lung but also provides better hemodynamic stability. Early institution of ECMO along with ultra-protective ventilation of lung and timed weaning is the key to successful management of severe ARDS due to swine flu. There are very few case reports of successful ECMO therapy in H1N1 associated ARDS available from Delhi.

Kasimode centre, the only base where the mechanised boats as well as country crafts were in use was used for preparing the fish calandar. Catch details of other miscellaneous groups like catfish, Polynemus, Chirocentrus and crustaceans and cephalopods are not incorporated in this calendar. The monthwise pooled CPUE of trawlers, mechanised gill nets and indigenous gears and the monthwise species composition of fish groups are illustrated

Calcibiocavitological investigations

Calcibiocavitation is a major poroblem in the marine environment and a detailed study on these aspects has been undertaken and the salient findings are presented here. Gregarious molluscs such as the sacred chank Xancus pvrum, mussels (both green and brown), rock oysters (Crassostrea spp.), pearl oysters, Thais rudolphi (Lam.) and corals which inhabit the southwest coast of Kerala and the Gulf of Mannar have been investigated. The wide fluctuations noted in the abundance and population structure of the various pests in the molluscan beds during the short period of two years clearly indicated that they were in severe competetion for suitable substrata and the shells of gregarious mollusks which inhabit this area provide ample opportunities for the pests to flourish. The incidence of boring sponges is found to be rather high among raft-cultured pearl oysters both at Tuticorin and Vizhinjam. It is difficult to control the infection of boring animals in the natural beds, but the low rate of incidence recorded year after year under suggests that the nature controls this to lower level.Another important observation was the wide distribution of the boring sponge C.vastifica in the Ashtamudi Lake, Quilonwhich may form a major threat to our future rock oyster farms along the estuaries

Experience paper on the operation of pilot project on oyster culture at Tuticorin

The technology of oyster culture was developed in India at the Central Marine Fisheries Research Institute. An experimental farm was established at Tuticorin bay in an area of 0.25 hectares. Different growout methods have been tried and it has been assessed that the shell string method could be practised with relatively low cost inputs with a production rate comparable to highly efficient systems such as rack and tray method or raft culture

The edible oyster culture

In 1970s the CMFR Institute initiated oyster culture through rack and tray method. Large scale spat collection, preparation of spat collectors, season and seed availability were studied. In 1980, a hatchery was set up with annual production capacity of one million edible oyster seed and the techniques involved in hatchery system were standardized. The seed were supplied to other centres of this Institute and Gujarat Fisheries Department. The production rates for rack and tray, string and stake method were estimated as 120 t and 22 t respectively. As part of extension, one lab to land programme, 8 training programmes, one workshop and a summer insitute were conducted. Results of experimental oyster culture work carried out at Mandapam, Madras, Bheemunipatnam, Kakinada, Mulki, Dharmadam, Ashtamudi and Cochin backwaters are given. Rearing 600 strings in 0.04 ha at Ashtamudi and harvesting 2.5t oysters pointed out 44.8% return with estimated production of 80- 105t/ha. Further research priorities on oyster culture aspects are indicated
