Library operation and management requires the performance of a number of repetitive, painstaking, labour- and time-intensive activities. Hence, in order to increase efficiency and effectiveness, many libraries are moving towards automation of the majority of their activities. Libraries are deploying Radio Frequency Identification (RFID) technology as a substitute for barcode systems for item identification and tracking, and this ultimately enables the automation of the majority of their processes. It is apparent from the available literature that research on RFID-related issues is largely concentrated on technical, organizational and implementation aspects, and less attention has been paid to understanding the use and user-satisfaction aspects. Therefore, this article aims to understand factors affecting the use of RFID systems and user satisfaction in a library context by empirically testing relevant constructs from DeLone and McLean's IS Success Model. A questionnaire-based survey was employed to collect data from a total of 181 respondents, who were all active users of an RFID-based library system. The findings from this study suggest that factors like system quality, use and user satisfaction positively influence consumer attitudes towards RFID-enabled services. The concluding section outlines salient points and briefly describes the associated limitations of this research, along with suggestions for future research directions.  相似文献

The possibilities of quantitative student observations during the transit of Venus, using simple equipment, are discussed. The equipment could also be used for safe observations of the Sun during eclipses, transits of Mercury as also for daily observations of sunspots. The annual variation in the angular diameter of the Sun as it passes from aphelion to perihelion and so on, could be measured with this simple equipment. School and college astronomy clubs would find it very useful to use this equipment for daytime astronomy activities and learning-oriented projects.  相似文献

马来西亚开放大学(OUM)90%以上的学生为在职人员。这些成年学生离开学校至少已经5年,而且大多数人的数学基础不好。因此,仅是在线学习加少量面授辅导的教学模式对他们来说还不能完全解决学习困难。学校试用了“课前指导工作室”与“补充指导”的教学方法,探讨了这一方法对学员的在线参与程度及考试结果的影响,运用源于探究团体模式的34项量表对在线论坛的内容进行了分析,结果表明,学员参加工作室与否同他们的期末考试成绩有很大关系。参加指导老师工作室及补充指导的学员与那些参加指导老师常规指导的学员相比,前者的在线参与程度及期末考试的平均分都存在着很大的差异。两组学员的数学探究团体模式平均分表明,两组学员在教学存在和认知存在方面有差异,但在社会存在方面基本相同。  相似文献

Hypomagnesaemia is common finding in current medical practice mainly in critically ill, post-operative patients and patients admitted to ICU in tertiary cancer cases. Magnesium has been directly implicated in hypokalemia, hypocalcaemia and dysrrthymias. We report a case of 60 year old patient, suffering from rectal carcinoma for a period of one year with confirmed hypokalemia, hypocalcaemia and hyponatremia. Magnesium supplementation corrected the underlying multiple electrolyte disturbances in the patient thus, establishing a positive correlation of magnesium with sodium, potassium and calcium.  相似文献

Pleural tuberculosis accounts for nearly 20% of Extra pulmonary tuberculosis. Adenosine deaminase, commonly used biomarker for the diagnosis, is non specific and there is paucity of literature on its correlation with conventional or newer methods for the diagnosis of extra pulmonary forms of TB. The aim of the study was to assess diagnostic potential of T cell function markers [interferon (IFN-γ), interleukin (IL-2) and IFN-γ/IL-2 ratio]; macrophage activation marker [neopterin]; and oxidative stress markers [protein carbonyl and malondialdehyde (MDA)] in pleural tuberculosis. 26 pleural TB cases diagnosed on the basis of suggestive chest X-ray and raised serum ADA levels and healthy controls were included in the study. Pleural fluid specimens were subjected to Zeihl Neelsen staining and culture on Lowenstein Jensen medium. Serum IFN-γ, IL-2, neopterin and protein carbonyl levels detection were done by ELISA and MDA levels were determined by measuring the thiobarbituric acid reactive substances. Median serum levels of IFN-γ, IL-2, IFN-γ/IL-2 ratio, neopterin, protein carbonyl and MDA were significantly different between cases and controls. Levels of all biomarkers except IL-2 were significantly higher in cases with contact history. Mean levels of ADA and ESR were 46.27 U/L and 46.62 mm/hr in PTB cases. AUC for IFN-γ, IL-2, IFN-γ/IL-2 ratio, neopterin, protein carbonyl and MDA were significantly discriminative for cases and controls. IFN-γ/IL-2 ratio was best discriminatory biomarker with highest area under ROC curve. Though no correlation was seen between ADA and any of the six biomarkers, ESR levels correlated significantly with all biomarkers except IL-2 by spearman’s correlation coefficient. Though all the circulating biomarkers under study provide useful supportive evidence for the diagnosis of PTB, further studies involving diverse control groups particularly non-PTB effusion are needed to validate these results.  相似文献

This paper investigates the benefits of overseas tertiary education for international postgraduate students enrolled at a research-intensive university in Malaysia, an emerging yet under-researched Asian education hub. The study is based on 55 semi-structured qualitative interviews with international students and academic and professional support staff. Our analysis identified three sets of benefits linked to specific economic, educational, social and cultural pull factors: academic success, building knowledge and skills, and contributing to home country on return. Our analysis illustrates the interplay between macro and meso-level actors and policies in shaping the micro-level experiences of international students. The paper contributes new insights into vital nuances in the nature and lived experience of the key benefits of international education relating to academic success and time, language learning and friendship, and employability and ‘giving back’.  相似文献

The prevalence of microalbuminuria was assessed in 174 albustix negative hypertensive patients by estimating albumin in the morning random urine samples by immunoturbidimetric method within four hours of voiding of urine. The urine samples were not stored and collected without any preservatives. The urinary albumin was calculated in terms of ratio with respect to urinary creatinine and expressed as albumin creatinine ratio (mg/g). Out of 174 albustix negative hypertensives, 58 (33.3%) patients were found to have microalbuminuria. The prevalence of microalbuminuria in males and females was found to be 34% and 30.7% respectively. No correlation was found between the Body Mass Index (BMI) and albumin excretion (r2 = 0.0271) and between duration of hypertension and urinary albumin excretion (r2 = 0.0042). Prevalence of microalbuminuria in nonsmokers and non-alcoholic hypertensives was 20%. The prevalence in alcoholics, smokers and both smokers and alcoholics was found to be 35%, 42% and 41% respectively. The high prevalence of microalbuminuria than the various reported studies on the subject demands establishment of a screening programme for microalbuminuria, implementation of specific intervention methods and education of hypertensive patients about the consequences of smoking and alcohol on possible involvement of renal system.  相似文献

Cystic fibrosis is a common autosomal recessive disorder usually found in population of white Caucasian descent. Now it is well documented the presence of CF disease in India with the advancement of laboratory testing. As once it was thought non existence of this disease in our population. Most of the phenotype of CF disease was in accordance of western population. Genetic analysis of CFTR gene in Indian CF patients revealed that most common mutation was delta F508 mutation. However, it was less than Caucasian population. CFTR mutations are also a causative factor in the pathogenesis of male infertility due to obstructive azoospermia. There are two most common mutation viz. IVS8-T5 and delta F508 which are responsible for congenital absence of vas deferens in male infertility patients. Elevated levels of sweat chloride at two occasions along with the presence of two mutations in CFTR gene was gold standard method for diagnosis of CF disease. It is noteworthy here that due to magnitude of Indian population, the total CF disease load would be more than many European countries. Clinical data demonstrate the prevalence of both classical and genetic form of CF in India.  相似文献

Through an exploration of two experimental schools, Oruaiti (1950s) and Discovery 1 (2000s), we aim to understand the socio-political contexts that create spaces for experimentation and examine their impact on mainstream schooling. Caught between competing, often contradictory, discourses such experiments struggle between the ‘regeneration’ and ‘reproduction’ functions of schooling. However, we argue that while they have limited impact on mainstream school reform, they contribute ideas of a democratic society and its citizenry. Consequently, they provide ‘windows’ into real-life laboratories in which social debates regarding the function and power of schooling, and specific visions of democracy are played out.  相似文献
