Evaluating E-resource Collections in a Business School Library: A Comparative Study of Aggregator Packages at Indian Institute of Management Ahmedabad Library

The need to continuously evaluate resource usage, whether in print or online, has been a challenge for libraries for a long time. The shift in resources to digital formats has made gauging the utility of resources more convenient as well as enabling cross database comparisons on various parameters. In this context, the article explores the aggregator databases subscribed by Indian Institute of Management Ahmedabad library. The study compares EBSCO's Business Source Complete, EBSCO's Academic Search Premier, Proquest's ABI INFORM Complete, JSTOR, and Project Muse packages in terms of the features available, usage, and the most used journals in these packages.     

HPLC method for amino acids profile in biological fluids and inborn metabolic disorders of aminoacidopathies

Quantification of total and individual amino acids in biological fluids such as plasma, urine and cerebrospinal fluid has an important diagnostic implication in laboratory medicine. The present paper describes protocols for the assay of total amino acids by modified method based on dinitrophenyl and HPLC profile involving pre-column derivatization with o-pthalaldehyde (OPA) derivatization, respectively. The method, based on the alkylation of-SH groups prior to OPA derivatization of amino acids followed by reverse phase high performance liquid chromatography, provide a comprehensive profile of more than twenty amino acids (including-SH group containing) in a single run lasting about 45 minutes. The present study, apart from establishing the normal profile of amino acids in plasma of Indian sub population, also presents HPLC profile for some of the rare amino acidopathies.     

HTTP 404-page (not) found: Recovery of decayed URL citations

Study investigates the availability, persistence and half life of URL citations cited in two Indian LIS journals articles published between 2002 and 2010. This study also investigates how researchers can resurrect lapsed URL citations cited in research articles, using Wayback machine. A total of 1290 URLs cited in 472 research articles published in Indian LIS journals spanning a period of 9 years (2002–2010) were extracted. Study found that only 18.91% (1290 out of 6820) of URLs cited in these journal articles. 39.84% of URL citations were not accessible and remaining 60.15% of URL citations were still accessible. The HTTP 404 error message-“page not found” was the overwhelming message encountered and represented 54.86% of all HTTP error messages. However 51.06% URLs were recovered from HTTP 404 error message. Study also noticed that the half-life of URL citations was increased from 6.33 years to 13.85 years after recovering missing URLs from Wayback machine.     

Evaluation of serum adenosine deaminase and 5′-nucleotidase activities as probable markers in ovarian cancer

Adenosine deaminase (ADA) and 5′-nucleotidase (5′-NT) activities were measured in sera of patients with ovarian cancer and patients with benign ovarian tumour. The results were compared with that of a control group consisting of healthy women. ADA levels were significantly increased (P<0.001) in the ovarian cancer group (n=50) but not in the benign group (n=28) when compared to the controls (n=20). The results indicate that ADA and 5′-NT levels may help to differentiate malignant conditions from benign tumours of the ovary in addition to the existing tests such as serum CA-125 levels and histopathological study.

Race-Specific High School Course Intensity and Student’s Post-secondary Education Attainment

Post-secondary educational attainment is an increasingly important prerequisite to many valued outcomes. This paper examines the association of racially-specific high school course of study with student’s postsecondary educational attainment using ELS 2002–2012 and a comprehensive measure of course intensity derived from students’ patterns of course-taking. Results support a partial presence of racially-specific association of high school course of study. We also find that only Asian-American and American Indian/Alaskan Native students in the middle course intensity and Asian-American students in high course intensity ranges are more likely to obtain at least a 4-year college degree than same-race students in the low course intensity group. However, the same pattern is not evident for White, African-American, multi-racial, and Hispanic students, indicating that they do not experience the same benefit from academically rigorous courses of study. Also, educational expectations do not mediate the relationships among race, course of study, and postsecondary educational trajectory differently for students of different racial groups, i.e., they do not play a larger role in mediating the relationship between course of study and postsecondary educational trajectory for White students.     

The social culture of work: work, employment and unemployment as ways of life

All labour is directed towards producing some effect. For though some exertions are taken merely for their own sake, as when a game is played for amusement, they are not counted as labour. We may define labour as any exertion of mind or body undergone partly or wholly with a view to some good other than the pleasure derived directly from the work.     

Salivary glycoproteins as indicators of oral diseases

The present study deals with the estimation of total carbohydrate, protein bound carbohydrate, bound fucose and sialic acid along with total protein in disease conditions like gingivitis, periodontitis and their comparison with the normals. The neutral hexose values in gingivitis (8.08±2.20mg/100mg protein) and periodontitis (12.5±2.16mg/ 100mg protein) decreased significantly when expressed per 100 mg protein compared to normals (19.8±1.89mg/100mg protein). This might be because of higher protein concentration in these two clinical conditions. The ethanol insoluble hexose values were significantly reduced in both these conditions compared to controls (3.71±1.64,5.91±1.63,7.65±0.86mg/100mg protein respectively). The ethanol soluble hexose values were also found to be drastically reduced. This decrease in saliva appears to be characteristic feature of oral diseases. In gingivitis and periodontitis fucose level was found to be increased compared to normals when expressed as a function of salivary volume. However in terms of protein concentration the values in gingivitis (2.95±1.59), periodontitis (3.26±0.98) and normals (3.20±0.50mg/100mg) were not different. Sialic acid in ethanol insoluble fraction of salivary samples mg/100mg protein was found to be significantly reduced in both gingivitis (0.78±0.33) and periodontitis (0.95±0.31) compared to controls (1.92±0.33)
