The purpose of research synthesis is to produce new knowledge by making explicit connections and tensions between individual study reports that were not visible before. Every effort of synthesizing research is inevitably premised on certain epistemological assumptions. It is crucial that research synthesists reflect critically on how their epistemological positioning enables them to pursue certain purposes while preventing them from pursuing other purposes. The literature on research synthesis methods is dominated by publications premised on positivist assumptions. The rhetoric of systematic reviews, best-evidence synthesis and What Works Clearinghouse privileges syntheses with positivist orientations. Contesting the hegemony of positivist research syntheses, this paper makes a case for research syntheses that are informed by diverse epistemological orientations. It illuminates how research syntheses with distinct epistemological orientations can serve complementary, equally worthwhile, purposes. 相似文献

Glucocorticoids and its receptor are known to be involved in the dysregulation of hormone and lipid levels. Therefore, we
evaluated the association of Bcl1 gene polymorphism of glucocorticoids receptor (GCR) gene variant with hormone and lipid levels in Northern Indians obese. A total of 435 obese and non-obese age matched subjects
were included in the case–control study. Lipid and hormonal levels were estimated using standard protocols. Analysis of +646
C>G NR3C1 gene polymorphism was done using PCR–RFLP. The frequencies of GR Bcl1, C>G genotypes and alleles did not differ significantly (P > 0.05) between obese and non-obese. The +646 G allele carriers had higher waist to hip ratio, blood pressure, insulin and
glucose levels than non-carriers in obese subjects while diastolic blood pressure and glucose in non-obese. The NR3C1, +646 C>G polymorphism did not associate with obesity. However, the GG genotype may modulate blood pressure, blood glucose
and hormonal levels in northern Indians. 相似文献

Current study is conducted to evaluate method verification of two locally available kits manufactured by DSI & BIORAD for quantitative estimation of Hepatitis B virus antibodies in human normal immunoglobulin by using International standard of National Institute of Biological Standards and Control. Four analyst perform five sets of test in duplicate analysing accuracy, precision, and limit of detection, sensitivity and specificity. Our results suggest that both DSI and BIORAD kits fulfil the validation criteria and are sensitive to detect up to 10 mIU concentration precisely and accurately. DSI kit is more precise at concentration 100 mIU and economically 4–5 times cheaper in local market; on the other hand, BIORAD kits provide larger detection range up to 1000 mIU. 相似文献

INTRODUCTION As one of the most interesting applications of image analysis and processing, facial expressions tracking has received great attention in the last few years. It can be explained by some reasons, such as increasing interest to human-computer-interaction (HCI), video conferencing systems, entertaining ap- plications, and automatic 3D face modelling. Ex- pression tracking is the process of retrieving facial expression information (i.e. location or relationship of facial feature… 相似文献

Objective: A series of 2-benzylideneaminonaphthothiazoles were designed and synthesized incorporating the lipophilic naphthalene ring to render them more capable of penetrating various biomembranes. Methods: Schiff bases were synthesized by the reaction of naphtha[1,2-d]thiazol-2-amine with various substituted aromatic aldehydes. 2-(2'-Hydroxy)ben- zylideneaminonaphthothiazole was converted to its Co(Ⅱ), Ni(Ⅱ) and Cu(Ⅱ) metal complexes upon treatment with metal salts in ethanol. All the compounds were evaluated for their antibacterial activities by paper disc diffusion method with Gram positive Staphylococcus aureus and Staphylococcus epidermidis and Gram negative Escherichia coli and Pseudomonas aeruginosa bacteria. The minimum inhibitory concentrations of all the Schiff bases and metal complexes were determined by agar streak dilution method. Results: All the compounds moderately inhibited the growth of Cram positive and Gram negative bacteria. In the present study among all Schiff bases 2-(2'-hydroxy)benzylideneaminonaphthothiazole showed maximum inhibitory activity and among metal complexes Cu(Ⅱ) metal complex was found to be most potent. Conclusion: The results obtained validate the hypothesis that Schiff bases having substitution with halogens, hydroxyl group and nitro group at phenyl ring are required for the antibacterial activity while methoxy group at different positions in the aromatic ring has minimal role in the inhibitory activity. The results also indicated that the metal complexes are better antibacterial agents as compared to the Schiff bases. 相似文献
