No full textWeeds are undesirable vegetation directly or indirectly inferring with human welfare. Conventional methods of weed control have failed due to one or other reason. Herbicide-resistant weeds are the main problem in weed control due to the number of weed biotypes resistant to herbicides that constantly increases by the continuous use of the same products for years. Development of alternative weed control methods is needed to help decrease reliance on herbicide use. Biological weed control is an alternative option for weed problems, particularly in agriculture and forestry. It is based on the use of natural enemies, particularly insects and pathogens to control weeds, as a sustainable, low cost and more environmentally acceptable method of weed control. One of the approaches to biological weed control using fungal phytotoxin applied in similar ways to conventional herbicides. Fungal phytotoxins are natural secondary metabolites produced by plant pathogenic fungi during host–pathogen interactions. They have received considerable particular attention for elucidating disease etiology, and consequently to design strategies for disease control. Due to wide differences in their chemical structures, these toxic metabolites have different ecological and environmental roles and mechanisms of action. This review aims at summarizing the studies on the possible use of fungal phytotoxin as a lucrative, novel source of secondary phytotoxic herbicidal compounds for management of broad spectrum, noxious and pernicious weeds
Evaluation and analysis of impact of subsidies on small scale renewable energy technologies dissemination: a case study of Nepal
No full textThe report has analysed the status of rural electrification using renewable energy technologies (RETs) and the current subsidy delivery modality of RETs in Nepal. As the Government of Nepal is subsidizing small scale renewable energy projects, it is important to evaluate and analyse the programme to make sure that a programme is running in an effective and efficient way while reaching the target group.
During the course of the research, primary information collected from the field has been compiled using appropriate tools/software (such as MS Office) and analyzed. Different sets of questionnaires were prepared, targeting different personnel ranging from the users’ level to the government policy level. The field survey methods include field observations of RETs installations and operations along with interviews with selected users on a random sampling basis to identify barriers to subsidy delivery and possible measures to overcome these barriers; to determine user satisfaction level and time period for subsidy delivery mechanisms.
The report started with the country background information and the rationale behind the study. This is followed by the literature review and information on the current status of small scale RETs in the country. Next it deals with the organizational structure and current subsidy delivery modality of RETs in the country. The evaluation of the effectiveness of the subsidy with the current subsidy delivery modality has been analyzed based on six parameters; Targets and Achievements, Impact of RETs, Subsidy Delivery System Efficiency, Transparency, Sustainability and Effectiveness.
The research shows that the subsidized government program has been successful in achieving its goal to provide basic energy services in rural areas through RETs in terms of its quantitative target. Although the subsidized program is successful in electrifying the rural communities via RETs, the poorest of the poor families are still excluded from the subsidy. The program seems to benefit more the rich and upper middle class families rather than the poor families for which the subsidy was intended. The high capital cost and long subsidy delivery process are the main important reasons for this failure. The author has proposed a new modality which might overcome the time barriers and bureaucratic process in the subsidy delivery mechanism and will decrease the lead time. This will in turn help to reduce the operational cost of the private companies and will encourage more players to enter the market, increase competition and result in lower system costs.
After identifying gaps in the current subsidy delivery modality, the project report ends with the recommendation of a new modality improving the current modality and filling the gaps identified. As this study has some limitations, as described in chapter one, the scope of further works has been listed at the end

Small Group Research, 51(6), 659–699. https://doi.org/10.1177/1046496420934541. This article was originally published in Small Group Research. The version of record is available at: https://doi.org/10.1177/1046496420934541. © The Author(s) 2020.At its 50-year milestone, we assess the Small Group Research (SGR) corpus to reflect on the development of group research over the past half century. To do this, we examine the evolution of the corpus’s context and content. We examine its context by assessing its impact, which journals it communicates with, and the internationality of its authors. We examine its content—the topics discussed in its articles—using keyword clustering and co-occurrence network analysis. We identify 10 research communities and track their relationships over the four editorial periods associated with the SGR corpus (lagged 2 years for influence): 1970–1981, 1982–1991, 1992–2010, and 2011–2019. Our analyses indicate that the global and local study of group dynamics has fluctuated over time and that phenomenologically based topics connect theoretical topics and stimulate theoretical development. We also provide three criteria to identify communities and topics of group research most likely to benefit from future integration.The author(s) received no financial support for the research, authorship, and/or publication of this article
Institutional Diversity and Capitalist Transformation in Rural Arunachal Pradesh
No full textThis paper contributes a preliminary analysis of the process of capitalist transformation in Arunachal Pradesh, one of the least studied regions of India. Primarily based on information collected through a field survey in eleven villages, the paper seeks to explain the nature and implications of institutional unevenness in the development of capitalism. Institutional diversity is not simply mapped across space; it is also manifested in the simultaneous existence of market and non-market institutions across the means of production within the same village or spatial context. In addition there is a continuous and complex interaction among these institutions which both shapes and is shaped by this incipient capitalist transformation. Against the near universal consensus of social theorists that non-market institutional forms and processes would decline with the expansion and consolidation of the capitalist economy, the evidence presented here suggests that institutional adaptation, continuity and hybridity are as much integral to the emergence of the market economy as are the processes of creation of new institutions and demise of others. There is no necessary correspondence between the emerging commercialisation of the different productive dimensions of the agrarian economy. These uneven processes of institutional diversity, hybridity and interdependence are deeply influenced by existing and emerging power relations. Primitive accumulation, which was thought to be an archaic feature of early capitalism, emerges as a continuing characteristic of the on-going agrarian and non-agrarian capitalist transformation.
Geostatistical modelling of soil properties towards long-term ecological sustainability of agroecosystems
No full textA profound grasp of the quantitative spatial heterogeneity and distribution of the soil physicochemical attributes is crucial in understanding agricultural landscapes for ensuring the provisioning of soil ecosystem services. However, the analysis of data from remote sensing, like NDVI, can be of help in analysing the capacity of the landscape to provide supporting ecosystem services such as primary productivity. The research investigated and addressed the dispersion of important soil physico-chemical attributes in agricultural lands of the temperate Himalayan region of India using a geostatistical method and combining normalized difference vegetation index (NDVI) time-series data and the regression Kriging method. A 206 soil samples were gathered and assessed for soil parameters like pH, EC, OC, and available N, P, K, Ca, and Mg from Kishtwar district of Jammu. The coefficient of variation (CV) for pH and electrical conductivity (EC) ranged notably from 8.75 % to 118.98 %, highlighting diverse soil characteristics critical for local management practices. Mean elevation averaged 2743.32 m (m), with a moderate NDVI of 0.15, indicating dynamics in vegetation cover. Soil pH ranged from intensely acidic to marginally alkaline, with varying EC levels. Seemingly high organic carbon (OC), nitrogen (N), and potassium (K) levels, accompanied by medium phosphorus (P), calcium (Ca), and magnesium (Mg) levels were found in the region. The study employed ordinary kriging (OK) to map the spatial distribution of soil parameters, utilizing mean square error (MSE), root mean square error (RMSE), and the Moran’s I index. Exponential models were the best fit models for OC, while spherical models were fit for pH, EC, N, P, and Ca. Mathematical models were best fit for K and Mg. Spatial analysis using spherical and exponential models revealed distinct distribution patterns for pH, N, P, Ca, and Mg. The results of the degree of spatial dependence from the semi-variogram analyses indicated a strong (0.06 %) to moderate (0.51 %) to weak (2.81 %) dependence. The interpolated maps showed a distinct gradient in elevation (1053–4413 m), OC (0.13–2.80 %), NDVI (−0.16–0.54), pH (4.80–8.00), EC (0.03–9.80 dS m−1), N (201.15–993.19 kg ha−1), P (3.00–96.00 kg ha−1), K (124.88–1110.71 kg ha−1), Ca (7.00–46.00 meq 100 g soil−1), and Mg (2.30–21.50 meq 100 g soil−1) at the regional scale, indicating a wide range of spatial soil heterogeneity. The heterogeneity maps of soil parameters generated by this research can be effectively used by land planners and farm managers at a regional scale for crop nutrient management to reduce soil contamination risk. These maps serve as baseline materials and effective tools for suitable land management strategies such as conservation-effective tillage, integrated nutrient management, and organic farming based on the spatial distribution of soil properties and they can significantly enhance the long-term ecological sustainability of agro-ecosystems’ management
Quality of life and self-reported disability in patients with osteoarthritis: Cross-sectional descriptive study
No full textBACKGROUND: Osteoarthritis (OA) is a chronic disease in which the cartilage in the joints deteriorates and the bones rub against each other, causing pain, stiffness, and restricted range of motion. This is an age-related condition that affects initially isolated joints or joints on one aspect of the body. The aim of the study is to identify quality of life and self-reported disability in patients with osteoarthritis.
MATERIALS AND METHODS: A cross-sectional descriptive study was conducted in Orthopedic O.P.D. of tertiary care hospital. Study was conducted on 150 samples with convenience sampling at orthopedic O.P.D. Data were collected with standardized tools SF-36 with domains physical functioning (PF), role physical (RP), vitality (VT), mental health (MH), role emotional (RE), social functioning (SF), bodily pain (BP) general health (GH), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaires with domains pain, stiffness, and functional disability. Descriptive statistics and inferential statistics were used for data analysis such as mean, frequency, percentage, standard deviation, and Chi-square test.
RESULTS: Out of 150 samples, 103 were females, 114 were Hindu, and 131 were married. Highest mean score in RE domain of SF-36 was 60 with SD 38.43 indicating that patients had low impact on quality of life, whereas lowest mean score was 35.33 with SD 32.67 indicating that patients had severe impact in RP domain. In WOMAC index, patients had highest pain in climbing stairs, stiffness during morning, and functional difficulty during doing heavy domestic work, whereas lowest pain in resting, stiffness in evening, and functional difficulty during lying in bed.
CONCLUSION: Patients with OA had poorer quality of life in domains PF, RP, VT, BP, and GH. Patients with osteoarthritis showed highest self-reported disability in terms of pain in climbing stairs, stiffness during morning, and functional difficulties in doing heavy domestic duties
