The advent of internet has brought in changes to many existing stable business models. With the technological shift, the concept of community writing has undergone several changes. Using a sample of 181 participants, it was found that online community, of late, has been greatly impacted by technology. Community writing involves amalgamation of writers in the internet space; collaboration among the writers has evolved as a crucial aspect. Moreover, the members of the community play a pivotal role in terms of reading, sharing and voting for the appropriateness of content. In addition, it was found that social media, ranking of the website, the community maturity lifecycle and the returns that the investors expect on their investment too have a role to play. In this backdrop, several factors have emerged as important in determining the performance of these communities. This paper aims to elicit those significant factors and analyse their interdependencies and influences in assessing the overall value of an online writing community. Based on the literature in this respect and the gap, an entire list of factors were noted and a framework was developed. This model was then tested using PLS-SEM tool. The inferences from this study can assist in giving priorities to certain factors, which are found out to be important, while making this assessment. It shall also facilitate better and efficacious decision making and aid in developing effective strategies. 相似文献

The concepts behind the technology of genetic modification of organisms and its applications are complex. A diverse range
of opinions, public concern and considerable media interest accompanies the subject. This study explores the knowledge and
attitudes of science teachers and senior secondary biology students about the application of a rapidly expanding technology,
genetic engineering, to food production. The results indicated significant difference in understanding of concepts related
with genetically engineered food stuffs between teachers and students. The most common ideas about genetically modified food
were that cross bred plants and genetically modified plants are not same, GM organisms are produced by inserting a foreign
gene into a plant or animal and are high yielding. More teachers thought that genetically engineered food stuffs were unsafe
for the environment. Both teachers and students showed number of misconceptions, for example, the pesticidal proteins produced
by GM organisms have indirect effects through bioaccumulation, induces production of allergic proteins, genetic engineering
is production of new genes, GM plants are leaky sieves and that transgenes are more likely to introgress into wild species
than mutated species. In general, more students saw benefits while teachers were cautious about the advantages of genetically
engineered food stuffs. 相似文献

This study addresses the hypothesis that stagnation of soybean yield on the farm can be improved by selection of a physiological
trait favoring carbon assimilate partitioning to terminally placed pods versus genotypes having axillary pods at close plant
spacing. 13C was fed to source-sink units comprising a leaf, axillary/terminal pods, and petioles at upper and lower positions of the
stem axis in two soybean cultivars, namely Shakujo and Enrei, at different densities of populations. The cultivars differ
significantly in architecture, Shakujo bearing a few hundreds of pods in close succession to one another in a terminally placed
raceme, in contrast to Enrei having axillary racemes. Pod yield per plant was higher in Enrei than in Shakujo at low density,
but Shakujo out-yielded Enrei at close spacing. Population density decreased yield per plant and altered the pattern of assimilate
partitioning significantly within the plants for both varieties. At high density more assimilates moved to the upper parts
at the cost of the lower parts. The terminally placed pods of Shakujo were advantaged to receive assimilates under density
stress. No benefit was accrued to pod filling of Enrei, however, under this condition. 相似文献

Serum malondialdehyde was measured in sixty-one falciparum malaria cases, which include thirty uncomplicated, and thirty-one
complicated with acute renal failure. Twenty-six healthy individuals were also studied as controls. Serum malondialdehyde
level was found to be significantly elevated in falciparum malaria induced acute renal failure cases when compared with uncomplicated
falciparum malaria (p<0.001) and healthy controls (p<0.001). A positive correlation with the raised urea, creatinine and bilirubin
levels were significant (r=0.62, p<0.025; r=0.65, p<0.05 and r=0.72, p<0.001 respectively) indicating the severity of complication
with rise of lipid peroxides in falciparum malaria induced acute renal failure cases. 相似文献

This work was undertaken to investigate correlation between oxidative stress and initiation of pathogenesis of pregnancy induced
hypertension (PIH). Fifty primigravidae in age group of 20–35 years and gestational age 28–42 weeks with PIH were taken as
cases. Twenty healthy primigravidae with no medical and surgical complications of pregnancy and with blood pressure ≤140/90
mm Hg served as controls. The cases were again subgrouped as severe preeclampsia (12 in number) and mild pre-eclampsia (38
in number). All of them were evaluated for serum malondialdehyde (MDA), Serum vitamin E and plasma vitamin C levels. The serum
MDA levels were raised significantly in women with mild preeclampsia (P<0.01) and in women with severe preeclampsia (P<0.01)
in comparison to normal primi gravida. The serum vitamin E levels were decreased in primi gravida with mild preeclampsia (p<0.1)
and in primi with severe pre eclampsia (P<0.1) in comparison to normal primi gravida but the fall was not statistically significant.
There was a significant fall (P<0.05) in the vitamin C levels in primi with mild preeclampsia than in the normal primi. The
vitamin C levels in severe preeclamptic patients were lower than the normal primi but the fall was not statistically significant
(P=0.10). The serum MDA and vitamin E showed a negative correlation in all the cases. The serum MDA and plasma vitamin C also
showed a negative correlation in the control and study group. This observation suggests that in hypertensive disorders of
pregnancy there is an imbalance between lipid peroxidation and antioxidant vitamin status because of oxidative stress. The
decreased serum concentrations of the antioxidant vitamins supports the hypothesis that lipid peroxidation is an important
causative factor in the pathogenesis of preeclampsia. The rise in antioxidants is probably to compensate the increased peroxide
load in severe preeclampsia. 相似文献

Pleural fluid malondialdehyde (PMDA) and serum effusion albumin gradient(SEAG) were estimated in 60 patients of pleural effusion
of diverse etiologies. The results were compared with Light’s criteria to distinguish between transudates and exudates. The
mean PMDA level was 0.68±0.24nmol/ml and 1.17±0.25nmol/ml in transudates and exudates respectively showing a statistically
significant (p<0.05) rise in exudates in comparison to transudates. SEAG registered a significant fall in exudates (P<0.001)
when compared with transudates. PMDA revealed a positive correlation with pleural protein(r=+0.30) and a significant negative
association with SEAG (r= −0.33).Sensitivity and specificity of PMDA were better than the parameters of Light’s criteria.
Whereas SEAG documented approximately equal sensitivity, specificity, positive predictive value (PPV) and negative predictive
value (NPV) with Light’s criteria. Therefore PMDA and SEAG can be taken together in addition to Light’s criteria to strengthen
the discrimination between transudates and exudates in borderline cases of pleural effusion. 相似文献

The incidence of autoimmune disorders that includes the connective tissue diseases has seen a rise in India in recent times. Antinuclear antibodies, the telltale sign of systemic autoimmune response, thus can be used as a screening tool and also to support the diagnosis of systemic autoimmune disease. The present retrospective cross- sectional analysis aimed to study the antinuclear antibodies profile (patterns and specific antibody reactivity) amongst suspected cases of auto-immune disorders at a tertiary care teaching hospital. The study retrieved and reviewed reports of 644 patients sent for ANA testing by indirect immunofluorescence assay over a period of 1 year by different specialty departments. Positive samples were further processed for anti-ds-DNA antibody and antibodies to extractable nuclear antigen. Data collected was statistically analysed. ANA pattern positivity was observed in 31% of cases and a positive antibody reactivity was seen in 66% of them. Female predominance (82%) was noted in both pattern positivity and antibody reactivity. High levels of pattern positivity and antibody reactivity was found in the young adults (45.9%). Amongst the ANA patterns, the nuclear homogenous pattern was found the commonest. The common antibodies associated with this pattern were anti-dsDNA and U1 Sm/RNP antibodies. A stronger fluorescence intensity on initial screening showed a higher confirmation rate for specific antibodies on immunoassay. High occurrence of positive ANA patterns in autoimmune disorders suggests its utilization as a screening tool for them and would also play an adjuvant to the diagnosis. Early knowledge about future autoimmunity will earn better prognostic achievements through better treatment interventions. 相似文献

Time compression in supply chains is a crucial aspect involved in the integration of warehousing and transport operations in the manufacturing industries. Sup- ply chain flows could be interrupted due to many sources of delays that lead to additional time in dispatching process and reduction in customer service level. The problem considered in this paper consists of long waiting times of loading vehicles inside the plant. This work presents a simulation-based study to minimize vehicle dispatching time in a steel wire plant. Value stream map is developed to present a system perspective of processes involved in the overall supply chain. Process activity mapping is com- pleted to provide a step by step analysis of activities involved in the vehicle dispatch process. A simulation model is developed for the system and a new model is proposed to improve the delivery performance by mini- mizing vehicles' waiting time. 相似文献

Insulin resistance and the resultant hyperinsulinemia exacerbate the reproductive abnormalities of Polycystic Ovarian Syndrome
by increasing ovarian androgen productions and decreasing serum sex hormone binding globulin. The present study was conducted
to estimate serum insulin and testosterone level in 44 PCOS cases and 32 control patients. Simultaneously the role of metformin
(an insulin sensitizing agent) in modulating insulin resistance and serum androgen level was also analyzed. A significant
rise in serum insulin and testosterone (P < 0.001) was observed in cases in comparison to control. Fasting Plasma Glucose to insulin ratio, a marker of insulin resistance
revealed a significant fall in PCOS group. Follow up of cases with metformin for 3 months revealed a significant fall in serum
insulin (P < 0.05) with improvement in insulin resistance along with a nonsignificant fall in testosterone level. Serum insulin registered
a significant positive correlation (P < 0.05) with serum testosterone revealing its etiological association. Thus administration of drugs ameliorating insulin
levels is expected to provide new therapeutic modality for PCOS. 相似文献
