Past research has considered the reflective practices of the teacher as an important activity in the learning cycle. Some of it has introduced the term ‘reflective teacher’, showing that such practice has become increasingly important.This paper discusses literature related to various means of collecting feedback from students, the socio-technical approach to management information systems (MISs) and reflective models. It documents the reflective practices that the author followed while teaching an MIS distance education course.The findings of this research show that actively reflecting on feedback collected from students could improve teaching quality and lead to better understanding for students in future cohorts. 相似文献
India is the main abode of theworld’s tallest flying bird called the Sarus Crane. Their population, however, has shown a steady
decline over the past few decades. Several factors are believed to be responsible for this. Alterations of the landscape to
agriculture leading to habitat loss and other socioecological factors are the main reasons of this declination. This article
will introduce some of these features and current status of this famous historical bird. 相似文献
Application of high input technologies has resulted in significant increase in agricultural productivity. There is, however,
a growing concern about the adverse effects of indiscriminate use of chemical fertilizers on soil productivity and environmental
quality. Cyanobacteria offer an economically attractive and ecologically sound alternative to chemical fertilizers for realizing
the ultimate goal of increased productivity, especially in rice cultivation. In a wetland rice ecosystem, nitrogen fixation
by free living cyanobacteria also significantly supplements soil nitrogen. 相似文献
This study focusses on the role of trust in knowledge sharing within the context of virtual communities of practice. Trust is widely accepted as an important enabler of knowledge management (KM) processes. We conceptualise trust across three dimensions, namely: competence, integrity and benevolence; we test hypotheses as to the effect of these facets of trust on knowledge sharing by surveying an intra-organisational global virtual community of practitioners. The results indicate that all three dimensions of trust are positively related to knowledge-sharing behaviour. Trust based on the perceived integrity of the community was found to be the strongest predictor of knowledge-sharing behaviour. Our findings suggest that the dimensions of trust buttress each other; although they are theoretically distinct, they appear to be empirically inseparable. We propose that in order for knowledge sharing to be enabled, trust must concurrently exist in all three dimensions. Implication to organisations in their recruitment policy is to include competence, integrity and benevolence in their sought-for attributes of new employees. KM practitioners also have to encourage these attributes in existing employees, who are potential members of on-line communities of practice. Knowledge sharing itself was conceptualised with three components – quantity (frequency), quality (usefulness or value) and focus (the degree to which an individual feels that they engage in knowledge sharing). Of the three components, focus exhibits the most significant relationship with trust factors. This finding makes knowledge sharing less tangible than perhaps would be expected. It suggests that establishing whether knowledge has been shared is more than counting the frequency or trying to evaluate the usefulness of the shared knowledge. These aspects are important especially to management, but to the individual who shares knowledge, her feelings of having shared knowledge appear to be more important. With the current understanding that knowledge sharing is more of a human activity than technology, it is important that any information system should be assistive in boosting users’ confidence that they are indeed sharing knowledge. If the systems do not re-enforce the users’ knowledge-sharing orientation, knowledge sharing may be discouraged. Notwithstanding the point made about knowledge-sharing focus, it is necessary to take into consideration all the components of knowledge sharing to fully capture the concept. This was well indicated when the combined variable of all (rather than individual) knowledge-sharing items had the strongest correlation with trust factors.
Pregnancy is associated with increased demand of all the nutrients like Iron, Copper, Zinc etc. and deficiency of any of these
could affect pregnancy, delivery and out come of pregnancy. With this consideration, the study was conducted on 80 mothers
and newborns and 20 age matched control women. Out of 80 mothers, 34 had Iron deficiency anemia and their Hb levels were below
9.0 gm/d1. Pregnant women had significantly lower Iron and Zinc levels while Copper and Total Iron Binding Capacity (TIBC) were significantly
higher (P<0.001). Newborns had significantly elevated Iron and Zinc levels and low levels of Copper and TIBC as compared to
their mothers irrespective of Iron deficiency anemia. Micronutrient status of newborn was found to be dependent on their mother's
micronutrient status. Besides, results also suggest micronutrient interactions, which are reflected in Iron/Zinc, Iron/Copper
and Zinc/Copper ratios. In view of this, there is need for proper, adequate and balanced micronutrient supplementation during
pregnancy to affect a healthy outcome. 相似文献
The study includes 102 confirmed cases of carcinoma breast with and without metastasis and 25 healthy non-pregnant females.
They were evaluated for blood levels of Ferritin, GSH, LDH, ALP, GGT and Hb before and 21 days after mastectomy. A significant
increase (p<0.001) was observed in ferritin, LDH and GSH levels in cancer patients without metastasis in comparison to normal
control subjects. Patients with metastasis had further elevated (p<0.001) levels of Ferritin, ALP and GGT as compared to non-metastatic
patients. Mastectomy in both the cases i.e. with and without metastasis resulted in non-significant decrease in all the biochemical
parameters suggesting that longer follow up could confirm post surgery decrease in the biochemical parameters. The results
of the study suggest cost effective, usefulness of Ferritin, ALP, GGT and GSH/Hb ratio in differentiating breast cancer patients
with and without metastasis which can be assayed in smaller laboratories. 相似文献
Iron deficiency anemia is one of the causes that lead to significant mortality and morbidity among pregnant women and fetus. The present study was undertaken to explore oral iron supplementation can modify the metal contents in pregnant anemic women. Iron and folic acid supplementations was given to 500 anemic women (mild = 200, moderate = 200, and severe = 100) and 100 age matched non-anemic controls daily for 100 days. Blood index values and plasma trace minerals were estimated as per standard protocols. Haemoglobin and ferritin levels were found significantly increased (p < 0.001) in anemic and control subjects after treatment. Moreover, the serum transferring receptor levels and total iron binding capacity were found significantly decreased in all treated groups. Iron (Fe), zinc (Zn) and copper (Cu) levels were found increased (p < 0.01) after oral iron supplementation groups. Moreover, selenium (Se) manganese (Mn) and were found to be decreased in all treated groups. Data provides the conclusion that iron and folic acid supplementation recovered the essential trace minerals, except manganese, which may lead to various complications including peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus. 相似文献
The present study included three groups: (A) age and gender matched control (n=24) with no previous signs of M. tuberculosis
complex (MTBC) infection, (B) patients (n=28) diagnosed with gastro-intestinal TB (GITB), (C) patients (n=50) with clinical
and histo-pathological signs of GITB, but were culture and AFB negative. Real time assay performed using fluorescence resonance
energy transfer hybridization probes showed a positivity index of 36 % in group C, i.e. 18 were found reactive from the total
50 cases studied. In addition, immune characterization of these 18 cases showed depleted CD4+ count and increased levels of IFN-γ and TNF-α cytokines. No positive case was found in group A, while in group B, out of
total 28 cases studied 27 were found positive. A combinatorial diagnostic approach for rapid detection and characterization
of GITB might provide specific therapeutic strategies for prevention and treatment of the infection in future. 相似文献
