In many countries, energy security is treated as a priority for the coming decades, and at the same time energy production from the vast majority conventional energy sources does not meet environmental protection criteria. Hence, the need to use renewable energy sources (RES), which can largely satisfy energy needs. The aim of the study was to identify possibilities of creating autonomous energy regions (ARE) in Poland, based on renewable energy sources. Attention was paid to the role and significance of the potential of rural areas in this respect, taking into account the possibilities of increasing energy production from these sources in individual regions of Poland. The research was conducted on a regional level (division into voivodships) and on a local level (division into powiats, which form voivodships). When assessing the potential for constructing ARE based on RES, the following energy sources were taken into account: water, wind, sun, biogas and biomass. It was found that the highest RES potential versus energy consumption can be obtained in powiats where the share of arable land and forests exceeds 80%. The research showed that in most regions of Poland (powiats, voivodships), there is a large potential for obtaining additional energy from RES, which would cover over 73% of the country’s demand for electricity. This could be the basis for building energy independence on a local scale. The results of the study indicated that as many as seven regions would become self-sufficient in terms of electricity demand.

Policies to “rebalance” funding away from nursing homes and toward home and community-based services (HCBS) have encouraged national trends of nursing home closure and an expansion of the HCBS industry. These changes are unfolding without a clear understanding of what services are available at the local level. The purpose of this study was: (1) to describe the current distribution of community-based services (CBS) in areas where nursing homes have closed and (2) to examine differences in availability of CBS using local market and population characteristics as regressors in a multinomial logistic model. We collected data on and geocoded CBS facilities and then used ArcGIS to define a 5-mile radius around all nursing homes that closed between 2006 and 2010 and compared these local market areas. In rural areas, availability of CBS does not appear to compensate for nursing home closures. Policies encouraging HCBS may be outpacing availability of CBS, especially in rural areas.

This research paper is the part of Research Project entitled “Impact of Elected Women Representatives in the Life and Livelihood of the Women in Rural Areas: With Special Reference to Tiruvannamalai District, Tamil Nadu” funded by University of Madras under UGC-UPE Scheme.The 73rd and 74th amendments of the Constitution of India were made by the government to strengthen the position of women and to create a local-level legal foundation for direct democracy for women in both rural and urban areas. The representation for women in local bodies through reservation policies amendment in Constitution of India has stimulated the political participation of women in rural areas. However, when it’s comes to the argument of whether the women reservation in Panchayati Raj helps or benefits to the life and livelihood development of women as a group? The answer is hypothetical because the studies related to the impact of women representatives of Panchayati Raj in the life and livelihood development of women was very less. Therefore, to fill the gap in existing literature, the present study was conducted among the rural women of Tiruvannamalai district to assess the impact of elected women representatives in the physical and financial and business development of the women in rural areas. The findings revealed that during the last five years because of the women representation in their village Panjayati Raj, the Physical Asset of the rural women were increased or developed moderately (55.8%) and Highly (23.4%) and the Financial and Business Asset of the rural women were increased or developed moderately (60.4%) and Highly (18.7%).

Abstract Background Globally, there is increased advocacy for community-based health insurance (CBHI) schemes. Like other low and middle-income countries (LMICs), Tanzania officially established the Community Health Fund (CHF) in 2001 for rural areas; and Tiba Kwa Kadi (TIKA) for urban population since 2009. This study investigated the implementation of TIKA scheme in urban districts of Tanzania. Methods A descriptive qualitative case study was conducted in four urban districts in Tanzania in 2019. Data were collected using semi-structured interviews, focus group discussions and review of documents. A thematic approach was used to analyse the data. Results While TIKA scheme was important in increasing access to health services for the poor and other disadvantaged groups, it faced many challenges which hindered its performance. The challenges included frequent stock-out of drugs and medical supplies, which frustrated TIKA members and hence contributed to non-renewal of membership. In addition, the scheme was affected by poor collections and management of the revenue collected from TIKA members, limited benefit packages and low awareness of the community. Conclusions Similar to rural-based Community Health Fund, the TIKA scheme faced structural and operational challenges which subsequently resulted into low uptake of the schemes. In order to achieve universal health coverage, the government should consider integrating or merging Community-Based Health Insurance schemes into a single national pool with decentralised arms to win national support while also maintaining local accountability.

Since the affirming of global warming, most wind energy projects have focused on the large-scale Horizontal Axis Wind Turbines (HAWTs). In recent years, the fast-growing wind energy sector and the demand for smarter grids have led to the use of Vertical Axis Wind Turbines (VAWTs) for decentralized energy generation systems, both in urban and remote rural areas. The goals of this study are to improve the Savonius-type VAWT’s efficiency and oscillation. The main concept is to redesign a Novel Blade profile using the Taguchi Robust Design Method and the ANSYS-Fluent simulation package. The convex contour of the blade faces against the wind, creating sufficient lift force and minimizing drag force; the concave contour faces up to the wind, improving or maintaining the drag force. The result is that the Novel Blade improves blade performance by 65% over the Savonius type at the best angular position. In addition, it decreases the oscillation and noise accordingly. This study achieved its two goals.

This study made an attempt to answer the question: Do the heterogeneous determinants of repayment affect the borrowers of diverse credit sources differently? The study is based on data collected from 240 households from three districts in the lower Brahmaputra valley of Assam through a carefully designed primary survey. Besides, the study uses the double hurdle approach and the instrumental variable probit model to reduce possible selection bias. It observes better repayment performance among formal borrowers, followed by semiformal borrowers, while occupation wise it is prominent among organised employees. It has been found that in general, the household characteristics, loan characteristics and location-specific characteristics significantly affect repayment performance of borrowers. However, the nature of impact of the factors influencing repayment performance is remarkably different across credit sources. It ignores the role of traditional community-based organisations in rural Assam while analysing the determinants of repayment performance. The study also recommends for ensuring productive opportunities and efficient market linkages in rural areas of Assam. The study is based on an original data set that has specially been collected to examine question that—do the heterogeneous determinants of repayment affect the borrowers of diverse credit sources differently in the lower Brahmaputra valley of Assam—which has not been studied before.

Abstract Homelessness is a reality for a growing number of Americans living in small towns and rural areas. However, unlike in cities, housing instability may be less visible. Using a photo-elicitation method (i.e., Photovoice), this study explores the meaning of place and obscured visibility to currently and formerly homeless older adults living in a small town in central Connecticut. Participants (N = 27) were recruited from a local service agency, given cameras and asked to photograph areas around town that were meaningful to them. Photographs were developed and followed by in-person, semi-structured interviews with participants in which photos and experiences during the project were discussed. Primary themes included belonging, generativity, social isolation, and place-making as meaning-making. The study culminated in a community photography exhibition in which photographs from the project were displayed in public spaces around town. Implications for community-based interventions to reach homeless groups in rural areas are discussed. Part of a symposium sponsored by the Qualitative Research Interest Group.
