The current study is aimed at investigating the effect of edaphic factors on the distribution and abundance of ants in different habitats of the central areas of Iran, while considering the vegetation. During 2018 to 2019, 20 stations from four habitats, including deserts, mountainous and submontane, plains and rural areas and urban areas, were selected. In general, a total of 311 sample units were collected from all the stations, out of which, 32 species belonging to 13 genera, nine tribes and three subfamilies were identified. The biological distribution and abundance of species were argued by computing the physical and chemical parameters of the soil, such as salinity, pH, total nitrogen, organic carbon, calcium and vegetation. The present study has demonstrated that the calcium content significantly affects the species richness of ants, although the impact of this element on various genera is different. We found that increasing in the abundance and richness of plant species has a positive impact on the abundance and richness of ants. Our results also show that some genera are meaningfully adaptable to a variety of habitats. In Kahak station, which is an urban habitat, with enormous diversity, 14 species were found, while in Sadrabad Historic Karvansara, a desert habitat, only Cataglyphis lividus (André, 1881) was collected. Cataglyphis bellicosus (Karavaiev, 1924), as the most abundant species, collected from 12 stations, was the most dominant species.

The study will analyze the impact of tourism by the type of special interest tourism to the environment. Impact on the coast and islands, the impact on vegetation, the impact wildlife, and the impact on urban areas and rural areas. Positive impact on the coast and the island is the effort for preservation and conservation of coral reefs, reef fish, giant clams and turtles, and encouraged to make environmentallyfriendly tourism activities. The negative impact is a damage to coral reefs from snorkeling activities, and the loss of traditional land allotment to the beach. The positive impact on vegetation is their attempt to biodiversity and conservation of vegetation typical of Publications, and reforestation activities is to replant mangrove. Negative impacts on vegetation is illegal logging and the clearing of trees to increase tourist attraction as supporters of the main activities. commercialization of the plant for souvenirs. Positive impact on wildlife is their conservation, preservation, and biodiversity, the breeding of animals and relocating the animals to their natural habitat. The negative impact is going hunting animals as souvenirs and tourist consumption, harassment of wildlife photography, animal exploitation for pertujukan, changes in animal instincts, and the migration of animals. Positive impact on urban areas and rural areas is happening arrangement karimunjawa towns and villages, and their empowerment. The negative impact of pressure on the land for the opening of a new tourist attraction, there are exchange in the function of residential land into commercial land, and the occurrence of traffic congestion, noise pollution, air pollution, and pollution aesthetics.  Keywords: Environmental Impact, Tourism, Snorkeling

The role and contribution of microfinance institutions (MFIs) is very important in development. Microfinance is a very important source of financial services for people and microenterprises that do not have easy access to banking and related services. The objective of this chapter is to assess empirically the impact of MFIs on development of India. This study aims to fill a gap in econometric assessments of microfinance institutions. Using data of MFIs operating in India and using savings of client as proxy for development, this chapter found empirical evidence for significant positive impact of microfinance institutions on development. While development in rural regions generally lags behind urban areas, this chapter found no statistical evidence for differences in the marginal impact of microfinance institutions subject to geographical positions. It can therefore be concluded that impact of MFIs on development in rural areas is positive and independent of environment.

This paper explores the impact of two shocks, trade liberalisation policies and decline in remittances, on welfare and poverty in Pakistan. It begins by reviewing the economy, which reveals that during the Nineties although import tariffs were reduced by 55 percent, poverty however remained higher in this period than in the Eighties. At the same time, Pakistan has experienced a slow down in the inflow of remittances, which reduces the incomes of households and puts pressure on the exchange rate resulting in reduction in the inflow of imports despite a reduction in import duties. Thus, in the absence of the effects of decline in remittances, the analysis of the impact of trade liberalisation policies may render biased results. This study overcomes this constriction and analyses the impact of trade liberalisation policies in the absence and presence of decline in remittances in a CGE framework with all the features necessary for trade policy analysis with poverty and remittances linkages. The simulation results show that a decline in remittances reduces the gains from trade liberalisation. The negative impact of remittance decline dominates the positive impact of trade liberalisation in urban areas. But, the positive impact of trade liberalisation dominates the negative impact of a decline in remittances in the case of rural areas. Poverty rises in Pakistan as a whole. It shows that the decline in remittance inflows is a major contributory factor in explaining the increase in poverty in Pakistan during the Nineties.

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%).

AbstractThe Southern Region of Europe is economically well-developed with highly industrialized urban areas and with great agricultural potential. The empirical analysis is based on an econometric assessment that measures the impact of the VAT on the rate of economic growth for years between 1996 and 2017. The empirical evidence highlighted a significant positive impact of VAT on economic growth, but a poor and ineffective use of the tax revenues during the period under review. Moreover, evidence revealed relatively high rates of VAT in the countries analyzed, with negative impact on the aggregate consumption and a diminishing effect of the consumer’s income.

Since E-Mobility is on the rise worldwide, large Charging Infrastructure (CI) networks are required to satisfy the upcoming Charging Demand (CD). Understanding this CD with its spatial and temporal uncertainties is important for grid operators to quantify the grid impact of Electric Vehicle integration and for Charging Station (CS) operators to assess long-term CI investments. Hence, we introduce an Agent-based E-Mobility Model assessing regional CI systems with their multi-directional interactions between CSs and vehicles. A Global Sensitivity Analysis (GSA) is applied to quantify the impact of 11 technical levers on 17 relevant charging system outputs. The GSA evaluates the E-Mobility integration in terms of grid impact, economic viability of CSs and Service Quality of the deployed Charging Infrastructure (SQCI). Based on this impact assessment we derive general guidelines for E-Mobility integration into regional systems. We found, inter alia, that CI policies should aim at allocating CSs across different types of locations to utilize cross-locational effects such as CSs at public locations affecting the charging peak in residential areas by up to 18%. Additionally, while improving the highway charging network is an effective lever to increase the SQCI in urban areas, public charging is an even stronger lever in rural areas.

The planning and organisation of public passenger transport in rural areas is a complex process. The transport demand in rural areas is often low, which makes it hard to establish and run a financially sustainable public transport system. A solution is integrated passenger transport that eliminates deficiencies and provides benefits for all participants in the public passenger transport process. This paper describes the impact of integrated passenger transport on mobility in rural areas and critically evaluates different literature sources. Integration of passenger transport in urban areas has been described in the context of rural areas, and the challenges of integration of public passenger transport specific to rural areas have been analysed. Through the application in urban and rural areas, the planning of integrated and non-integrated passenger transport has been functionally analysed. The analysis found an increase in the degree of mobility in the areas that use integrated passenger transport compared to the non-integrated one. This research of the literature review has identified the rural areas of mobility as under-researched. The mobility research can set up a more efficient passenger transport planning system in rural areas.

n 2017 the 500th anniversary of the Lutheran Reformation was celebrated. Then there was a huge discussion about the impact of the Reformation on church, culture and society. In this article and in a second one that follows, this question will be raised, especially in Icelandic context.Here it is assumed that it is only possible to state that a change has occurred or a novelty has arised because of Lutheran influence if it can be demonstrated that the Reformation is a necessary prerequisite for the change / innovation being discussed. Here it is particularly pointed out that various changes that until now have been traced to the Reformation can have been due to the development of the central-con-trolled state power. It is also pointed out that, due to the small population, rural areas and simple social structure, various changes that occurred in urban areas did not succeed in Iceland until long after the Reformation. Such cases are interpret-ed as delayed Lutheran effects. Then, in Iceland, many changes, which were well matched to the core areas of the Reformation, did not work until the 18th century and then because of the pietism. Such cases are interpreted as derivative Lutheran effects.In Iceland two generalizations have been evident in the debate on the influence of the Lutheran Reformation. The first one emphasizes an extensive and radical changes in many areas in the Reformation period and subsequent extensive decline. It is also stated that this regression can be traced directly to the Reformation and not to other fenomenons, e.g. the development of modern, centralized state. The other one states that the Reformation was most powerful in the modernization in both the church and society in Iceland.This article focuses on the influence of the Reformation on religious and church life. Despite the fact that the Reformation has certainly had the broadest and most direct effects on this field, it is noteworthy that the church organization itself was only scarsely affected by the Reformation. After the Reformation the Icelandic church was for example almost as clergy-orientaded as in the middle Ages.
