The Impact

The aim of the study was evaluation of clearcutting effect on water regime in a tree harvesting area. The results was made on the  basis of the study carried out in Rakowski Ditch catchment, in Wielkopolska lowland in Poland. It was found that a more useful method  to establish the effects of clearcutting is to is to compare the groundwater table level in the post-clearcutting area with that in a control area than to analyze the groundwater table level changes in the same area before and after the clearcutting. Regression analysis is a particularly useful tool in groundwater regime analyzes. The results obtained in this study  indicated that the groundwater regime changes in the post-clearcutting area were manifested as an increase in the average groundwater levels. The major changes in the  groundwater table after clearcutting were observed in the  minimum levels,  while the lowest changes took place in the maximum groundwater levels. The variation in  groundwater levels was higher in the period after clearcutting than in the period before it. The analysis of linear regression of groundwater levels in the well located in clearcutting and that in the control area confirmed the change in the  groundwater regime in the post-clearcutting area. Stronger relations in the period before clearcutting were observed. Key words: clearcutting, groundwater, forest catchment, swampy habitats

Abstract Groundwater table levels in a river valley depend, among other factors, on meteorological and hydrogeological conditions, land use and water levels in watercourses. The primary role of a watercourse is to collect surface and groundwater, and it becomes an infiltrating watercourse at high water levels. Changes in groundwater levels and the range of these changes depend chiefly on the shape, height and duration of the flood wave in the river channel. The assessment of flood wave impact on groundwater was based on long-term measurements of groundwater levels in the Odra valley and observations of water levels in the river channel. Simulations were performed with the use of in-house software FIZ (Filtracja i Zanieczyszczenia; Filtration and Contamination), designed for modelling unsteady water flows within a fully saturated zone. A two-dimensional model with two spatial variables was employed. The process of groundwater flow through a porous medium, non-homogeneous in terms of water permeability, was described with Boussinesq equation. The equation was solved with the use of finite element method. The model was applied to assess groundwater level fluctuations in the Odra valley in the context of actual flood waves on the river. Variations in groundwater table in the valley were analysed in relation to selected actual flood water levels in the Odra in 2001-2003 and 2010. The period from 2001 to 2003 was used to verify the model. A satisfactory agreement between the calculated and the measured values was obtained. Based on simulation calculations, it was proved that flood waves observed in 2010 caused a rise in groundwater table levels in a belt of approximately 1000 metres from the watercourses. It was calculated that at the end of hydrological year 2009/2010, the highest growths, of up to 0.80 m, were observed on piezometers located close to the Odra river channel. The passage of several flood waves on the Odra caused an increase of subsurface retention by 3.0% compared to the initial state.

Purpose – The purpose of this paper is to examine the factors affecting the financial sustainability of the Indian Micro Finance Institutions (MFIs) post-Andhra Pradesh (AP) crisis Design/methodology/approach – Regression analysis is used to test the significance of the independent variables on the variable of interest, i.e. the operational self-sustainability. Three-stage regression analysis, i.e. Partial F-test, residual analysis and Box–Cox-type transformations is applied to see the impact of the variables on financial sustainability of the Indian MFIs. The study is based on the data of the Indian MFIs during three fiscal years from 2010-2011 to 2012-2012 reported in the Microfinance Information Exchange (MIX). Findings – The authors’ results indicate that in 2010-2011, the linear regression model seems to be good fit to the data, whereas in 2011-2012 and 2012-2013, the appropriateness of the linear regression models seems questionable (the error distribution seems to be skewed). It is observed that square root of the dependent variable exhibits adequate fit for 2011 and 2012. Therefore, a substantial change in the model for estimating sustainability of Indian MFIs is observed in the post-AP crisis era. It is observed that portfolio quality and capital management are important determinants for the financial sustainability of the MFIs. Practical implications – This study identifies the factors affecting the sustainability of the Indian MFIs, especially after the reforms following the AP crisis in India. The study suggests that from 2012-2013, the factors such as write-off ratio, capital-to-asset ratio, ratio of financial revenue to assets and provision for loan impairment-to-asset ratio are the main factors which have significant impact on the operational self-sufficiency (OSS) of Indian MFIs. This indicates that the quality of portfolio must be improved to reduce the vulnerability of the Indian MFIs. Social implications – After the AP crisis, the performance of Indian MFIs is stabilized to a greater extent. The various performance indicators are improving. Originality/value – The paper provides a detailed comparative analysis of the factors effecting financial sustainability of the Indian MFIs, before and after the regulatory reforms in 2011. A substantial change is observed after 2011-2012. Such a study on the Indian microfinance sector seems to be new (to the best of the authors’ knowledge).

Reservoirs system in upstream of Ba River has been affecting to the hydrology and sediment regime at the downstream. Sediment imbalance causes consequences such as erosion at river bank, lack of sediment supply to downstream areas and deposition/erosion in estuaries. This study focused on a quantitative assessment of the impact of Ba Ha reservoir and Song Hinh reservoir on sediment regime at the Cung Son hydrological station (12 km downstream of Ba Ha reservoir and 45 km from the mouth of the Da Dien river). Research used analytical and statistical methods with flow and suspended sediment data measured at the Cung Son hydrological station from 1977 to 2016. The results show that the system of these two reservoirs has a huge impact to the sedimentation regime, especially after the operation of Ba Ha reservoir. The average amount of sediment in the period before and after 2008 significantly reduced from about 2.5 million to about 1 million tons per year.

Abstract ObjectiveTo investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the continuity of care (COC) in hypertension patients. Additionally, the factor of whether participants were treated by telemedicine or not was also considered.MethodsNational Health Insurance and Medical Aid claims This study used data from the Republic of Korea between 2019 and 2020. The multiple regression analysis was performed to identify the differences in visits and the Most Frequent Provider Continuity (MFPC) of hypertensive patients before and after the COVID-19. To confirm the effect of telemedicine, additional analysis was performed with data that deleted cases that received telemedicine.FindingsA total of 5,791,812 hypertensive patients are included in this study. When the confounding variables were adjusted, the MFPC decreased by 0.0031 points after the COVID-19. It also showed the same results for MFPC when telemedicine cases were excluded. The number of outpatient clinic visit days decreased by 0.2930 days after the COVID-19. Without telemedicine cases, the number of outpatient clinic visit days decreased by 0.3330 days after the COVID-19.ConclusionThe COVID-19 protocols did not affect hypertension patients' COC but impacted their outpatient frequency. Additionally, when telemedicine cases are considered, COC was the same, but the patient’s outpatient frequency had decreased, but not as much as when telemedicine cases were considered.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”).

Efficiency And Productivity

The Financial Master Plan (2001- 2010) aims to enhance the capacity of banking industry so that higher effic iency and productivity can be reaped in the future. This study seeks to determine the impact of merger on the efficiency and productivity ofcommercial banks in Malaysia for the period 1995 until 2005. The study uses a non-parametric approach, nam ely DEA (data envelopment analysis?) to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs are used. Amongst the findings are those banks exhibit higher efficiency score after the merger and thefo reign banks are more efficient than the local banks. Productivity of the banks is calculated in both periods, before and after the merger: The results show that, it is the local banks that have improved the most after the merger. The main source of productivity is technical change or innovation. The findings support the existing policy of having larger domestic banks in term of size.
