Purpose: The key informants in a village setup were studied to understand the existing social and knowledge systems of farmers, their structure, and relationships between different actors. The purpose is to identify different channels of information and use them as a means to disseminate agricultural technologies and related information to farmers.
Design: We use the network map analysis in a case study approach as a tool to demonstrate the linkages between the key actors and stakeholders in the information network of farmers.
Findings: The government institutions are well networked among themselves but have limited interactions with non-government sources. Farmers in Bihar have strong linkages with few network actors, who are important nodes in the social knowledge network. The study showed heterogeneity and complexity in the network shape and structure across different districts.
Practical Implications: Knowledge networks and social networks are the drivers of information sharing and play a significant role in the diffusion of agricultural technology and related knowledge. Understanding these networks provides a platform for introducing the agricultural technologies and getting connected to a wider group of farming communities.
Theoretical Implications: The study shows that the network is formed by different actors and their role determine the nature and shape of the network. Knowledge of this heterogeneity is important in designing or revamping agricultural information systems.
Originality: Information and knowledge networks are least explored in the agricultural information dissemination process. Some studies have shown the role of actors and social networks, but this study uniquely explores and presents the heterogeneity of these networks. 相似文献

The objective of the present study was to investigate the antioxidant status and the extent of oxidative DNA damage in lymphocytes and their relation with essential hypertension (EHT). A total of 100 South Indian subjects aged 30–65 were included for the study. Of these 50 were normotensive controls (group-1) with blood pressure ≥120/80 mm Hg, 50 were newly diagnosed (group-2) and were not on any antihypertensive drugs, but had systolic blood pressure ranging between 140 and 160 mmHg and diastolic blood pressure 95–100 mmHg and 50 newly diagnosed essential hypertensive patients underwent drug therapy for 1 year was considered as group-3. Enzymatic and non-enzymatic antioxidants significantly decreased and lymphocyte DNA damage was significantly increased in newly diagnosed hypertensive patients compared with control group. The major decrease in DNA damage and significant improvement in enzymatic and non-enzymatic antioxidants were observed after 1 year of antihypertensive therapy in treated group compared with newly diagnosed hypertensive patients. Total antioxidant status and lymphocyte DNA damage showed a strong negative correlation in all the three groups. Essential hypertension associated with oxidative stress which in turn causes genotoxic susceptibility to variety of disease including cancer. In the absence of DNA repair process and DNA checkpoint mechanisms, the genomic integrity is susceptible to extensive damage. In our study, increased oxidative DNA damage and decreased antioxidant levels were frequently observed in the newly diagnosed essential hypertensive patients, suggesting that oxidative stress is important in the pathogenesis of EHT. Therefore, the present study has additional clinical implication. Further investigations with large number of patients along with antioxidant supplement are highly warranted. 相似文献

One of the most intriguing aspects of the recent empirical literature on FDI-related spillover effects is the increasing identification of mixed results. A few studies, particularly in advanced countries have found positive effects; however, a more common scenario in recent studies is the prevalence of insignificant or even negative effects. This is despite the fact that theory predicts substantial positive effects in association with a supposed technological superiority of MNCs relative to domestic firms, particularly in the context of less advanced countries. In this paper, by distinguishing subsidiaries according to their orientation to carry out creative vs. exploitation activities in the host economy, we are able to distinguish situations with positive and negative spillover effects, and we explain why they may be emerging. More specifically, we find that only subsidiaries that are oriented to technologically creative activities have a significantly positive effect in India. In contrast, subsidiaries oriented mostly to technologically exploitative activities generate negative effects in some circumstances. The implications for theory and policy are discussed. 相似文献

This article aims to study the publishing trends in South India, including the states of Tamil Nadu, Kerala and Karnataka.
It also gives an insight into the markets in South India for English and Regional language books. As many international publishers
are moving towards the Indian book market, it is necessary to understand the culture and diversities of the country which
prove to be the biggest hurdle in marketing and promotion. This article gives detailed information on General trade, Academic
and School book markets. It also lists the key distributors, retailers and publishers in South India. The last page of the
article details the entry barriers for international publishers and proven techniques adopted by other publishers. Partnership
with Indian companies has worked well for many international publishers. All the statistics and data have been collected and
referenced to the best knowledge of the author. 相似文献

Establishment of non-invasive urinary biomarker for the early prediction of essential hypertension (EH) is important. We evaluated
whether estimation of urinary DNA, serves as a marker to predict the extent of cellular oxidative stress in essential hypertension.
A total of 180 South Indian subjects aged 30–65 were recruited for the study. Of these hypertensive subjects investigated,
30 were newly diagnosed and were not on any antihypertensive drugs, but had systolic blood pressure 140–160 mmHg and diastolic
blood pressure 95–100 mmHg and 75 hypertensive patients who already on drug therapy for one year and 75 were South Indian
normotensive healthy controls with blood pressure ≤ 120/80 mmHg. The 8-OHdG level in urine was significantly increased in
hypertensive patients (both newly diagnosed and who already on drug therapy) compared with control group. The significant
increase in 8-OHdG was observed in newly diagnosed hypertensive patients compared with hypertensive patients who already on
drug therapy. There was a significant decrease in serum TAS value in essential hypertensive group when compared to control
group. The urinary 8-OHdG was independently correlated with serum TAS. Decreased TAS levels, which reflect to increased oxidative
stress, may be the reason of increased urinary 8-OHdG in South Indian hypertensive patients. Our preliminary data suggest
that the competitive ELISA for 8-OHdG appears to be a simple method for quantifying the extent of oxidative stress. 相似文献

A beautiful monocarpic palm of the Western Ghats, talipot which through the ages played a silent role in the culture, economy and ecology especially of the west coast of South India, is facing an uncertain future mainly due to negligence. Much could be done to bring back this palm from obscurity into the mainstream of conservation. 相似文献
