An investigation into the English language experiences of Indian international students studying in New Zealand universities

ABSTRACT

Language proficiency is highlighted in the literature on the adjustment and security of international students. India is the second top source country for mobile students globally, but few studies have focused explicitly on students from India. The purpose of this study was to examine the English language experiences of Indian students at New Zealand universities. This mixed-method study utilised a questionnaire (n?=?109) and interviews (n?=?15). Collectively the participants had high levels of confidence and proficiency in English language and adjusted more rapidly than many international students to the new academic environment. Major differences experienced by the participants between India and New Zealand related to unfamiliar forms of academic writing and tasks, and on the role of learning support services. Formal high value assessment was for some the first indication of a problem with writing. While most students adjusted through error-based learning others struggled with argumentation and avoiding plagiarism. These findings have relevance for local and international students. We recommend the use of, and research on, early low-stakes assessment of writing and on effective support services for students transitioning into new academic contexts.     

Fighting Against Heavy Odds: An Indian Perspective on Sports History

Abstract

It is difficult to ascertain whether the history of sport has crossed its adolescence in India or not. To establish its credibility as a viable academic discipline has proved something of a struggle for those Indian scholars engaged in its research in the past. In the light of my experiences of doing research and editing a journal on sports, and teaching the history of sport at the postgraduate level over the past two decades, I intend to argue that the challenges confronting sports history could be overcome only if the teaching of sports history in the Social Sciences goes hand in hand with serious research and publication.     

A Community Based Study of the Relationship Between Homocysteine and Some of the Life Style Factors

Till date no community based data on plasma homocysteine is available in North Eastern Region. Hence, the present study was conducted to analyze and correlate the plasma homocysteine level with some life style factors like diet, alcohol intake, smoking habit and body weight, in a cross-section of population. 12 h fasting samples of 970 apparently healthy, Assamese population of both genders in the age group of 35–86 years, mostly from the urban area of Assam were tested for plasma total homocysteine level over a period of 3 years. Out of 970 volunteers, hyperhomocysteinemia was detected in 533 (55%) individuals with a mean value of 18.41 μmol/l. Of that hyperhomocysteinemia, 89.1% were in the range of moderately high and rest 10.9% were intermediate high. Another finding was that males had a tendency towards greater value (mean = 20.36 μmol/l) than females (mean = 16.37 μmol/l). It was observed that the relationship of homocysteine levels to gender and some of the life style factors were also significant.     

Crowns and crypts

Crowns and crypts constitute a very interesting and important class of complexing ligands. Besides many metal complexes, these ligands made possible the formation of a variety of unusual species among which ‘alkalides’ and ‘electrides’ require special mention. The crowns and crypts are widely studied due to their increasing use in various improbable chemical and physical processes. Further interest in these ligands lies in their use as biochemical models. A brief discussion on the crowns and crypts is presented here.     

Can India’s “literate” read?

This paper takes a close look at India’s literacy rate by exploring whether the officially “literate” can read and at what level. In a large sample, aged 7+, drawn from four Hindi-speaking states, two methods were used to measure literacy. One was the standard Census Method (CM) which relies on self-reporting and the other was a Reading Method (RM) which required the same individuals to actually read a simple text at grade 2 level. The findings revealed a substantial difference between the reading literacy rates obtained by CM and RM. CM over-reported RM by 16%. The overestimation was higher for males. Decoding skills were found to erode in most cases after completion of primary schooling, assuming no further education. A minimum grade 8–9 education was required for decoding skills to not deteriorate after schooling.     

PAI-1 Study in Thalassemia Major Patients Receiving Multiple Blood Transfusion

Thalassemia is a congenital hemolytic disease which is treated by repeated blood transfusion. Chronic iron overload is currently considered to be the primary cause of mortality in β-thalassemia, mainly due to the induction of left-sided cardiac failure. Iron overload results from a number of mechanisms associated with the disease itself. In addition to chronic iron overload thalassemic patients are more prone for procoagulant status which in turn lead to clinical thrombotic events. The hypercoagulable state in thalassemia is due to multiple elements, a combination of which is often the drive behind a clinical thromboembolic events. PAI-1 study was done in thalassemia major patients receiving multiple blood transfusion as a marker for procoagulant status. Total of 30 thalassemic patients on repeated blood transfusion was included in the study and total of 30 healthy age and sex matched controls were included in the study. It was also found that there was significant differences between cases and controls. The mean level of PAI 1 in controls was 3047 ± 414 pg/ml, the value in cases was 3683 ± 358 pg/ml. The level was significantly increased (p < 0.05) in the cases compared to controls. PAI-1 levels were also compared with the total number of blood transfusion which correlates well.     

Antioxidant activity of ethanol extract of rhizome ofPicrorhiza kurroa on indomethacin induced gastric ulcer during healing

Oral administration of ethanol extract of the rhizome ofPirorhiza kurroa at a dose of 20mg/kg body weight, for 10 consecutive days, was found to enhance the rate of healing on Indomethacin-induced gastric ulcer in rats, compared to the ulcerated group without treatment. The level of peroxidised lipid, in terms of thiobarbituric acid reactive species (TBARS), in gastric tissue, was increased in ulcerated rats which was restored to near normalcy on treatment with ethanol extract. The specific activity ofin vivo antioxidant enzymes, viz SOD and catalase and total tissue sulfhydryl (thiol) group, which were markedly decreased in ulcerated group, were found to be significantly elevated (p<0.05), on treatment with the above extract, at the specified dose, compared to the indomethacin—induced ulcerated group without any supporting treatment. The present study thus suggests that the ethanol extract of rhizome ofPicrorhiza kurroa, at the dose of 20mg/kg body weight, accelerated the healing of stomach wall of indomethacin induced gastric ulcerated rats by anin vivo free radical scavenging action.     

Discrete time second order sliding mode observer for uncertain linear multi-output system

This paper presents a second order sliding mode observer (SOSMO) design for discrete time uncertain linear multi-output system. The design procedure is effective for both matched and unmatched bounded uncertainties and/or disturbances. A second order sliding function and corresponding sliding manifold for discrete time system are defined similar to the lines of continuous time counterpart. A boundary layer concept is employed to avoid switching across the defined sliding manifold and the sliding trajectory is confined to a boundary layer once it converges to it. The condition for existence of convergent quasi-sliding mode (QSM) is derived. The observer estimation errors satisfying given stability conditions converge to an ultimate finite bound (within the specified boundary layer) with thickness O(T²)$O\left(T^2\right)$ where T is the sampling period. A relation between sliding mode gain and boundary layer is established for the existence of second order discrete sliding motion. The design strategy is very simple to apply and is demonstrated for three examples with different class of disturbances (matched and unmatched) to show the effectiveness of the design. Simulation results to show the robustness with respect to the measurement noise are given for SOSMO and the performance is compared with pseudo-linear Kalman filter (PLKF).
