In this study I develop artificial neural network models - ANN - in line with the conditions of the Egyptian economy, by building an optimal efficiency frontier and then comparing the actual performance of the Egyptian economy with that limit, which includes the lowest possible variations for both inflation and output. As for the new contribution to this study, it is to calculate the optimal inflation rate and the optimal output level in the Egyptian economy through a model that combines the higher predictive power of feed forward neural network models, and the high explanatory power of a stationary or random walk stochastic models, in order to obtain the fitted values of the optimal output level, and the optimal inflation rate. It is clear from the results of the study, the extent of the essential congruence between the actual Egyptian economic performance during the study period and the economic performance index that was built through the new contribution of this study.","PeriodicalId":298738,"journal":{"name":"international journal of research in computer application & management","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124670427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Actually, the efficient utilization of existing resources becomes crucial for strengthening the healthcare delivery. The objective of this study was to measure technical efficiency of five cardiology wards, using an innovative nonparametric approach through an aggregated efficiency at patient level. It can assist practitioners to understand the underlying causes of clinical practice inefficiency. Linearized Free Disposal Hull using the non-radial input directional distance function provide a efficiency scores at the patient level and aggregate scores at ward’s level. The cardiology wards operate at high inefficiency. Through the 217-treated diagnosis' disease, 50 are the greatest sources of inefficiency. Each ward could save more than 50% of inputs used. The decision makers can ensure the optimum utilization of the available resources through a new design of the management and clinical practices of these wards. High inefficiency is due to the lack evaluation, accountability and effective management of public hospitals.","PeriodicalId":298738,"journal":{"name":"international journal of research in computer application & management","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131277881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However political risks have been blamed for failure to attract private investments in equally measure as their developed partners. This article looked at political risks influencing the performance of PPP renewable energy projects in Kenya. The study adopted a pragmatic paradigm and employed a mixed methods approach, correlational and descriptive survey design. Quantitative data was collected by use of a self-administered questionnaire and an interview guide was used to collect qualitative data. A sample size of 263 respondents was drawn from a target population of 769 using the Yamane formula. For descriptive statistics the study used the mean and standard deviation. For inferential statistics the study used Pearson’s Product Moment Correlation (r) and Multiple Regression while the F-tests were used in hypothesis testing. The study established a significant influence of political risks r = 0.572, F (1,205) = 99.771, R2 = 0.327 at p<.05 H0 was rejected. The study concluded that there was a significant influence of political risks on the performance of PPP renewable energy projects in Kenya. Based on this finding the study recommends sustainable political stability.","PeriodicalId":298738,"journal":{"name":"international journal of research in computer application & management","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134052166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The success of every organization depends on its capital mix or structure. This places a greater responsibility on financial managers to decide the best capital combination that will maximize shareholders’ wealth. Due to the abstract nature of capital structure in an organization, this paper attempts to examine the influence of capital structure on the financial performance of banks in Ghana. The study uses debt ratio (DR) as proxy for banks capital structure and uses return on assets (ROA), return on equity (ROE) and earning per share (EPS) as proxies for banks performance measurement in the country understudy. The study sampled 7 banks out of the 11 banks listed on the Ghana stock exchange (as at 2017) over a seven-year period from 2008 to 2014 and data from their respective annual financial statements were extracted. It was concluded that capital structure has a negative effect on banks performance as the results confirms various studies reviewed.","PeriodicalId":298738,"journal":{"name":"international journal of research in computer application & management","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115526659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The health production function expresses the functional relationship between health status and health care inputs, while life expectancy at birth has been widely used as an indicator of population health status of a country and health care inputs can be categorized into three broader categories named economic factors, social factors and environmental factors. It is a prior work to estimate health production function for the south Asian countries. A balanced panel data of seven South Asian countries are taken for the period of 1995-2015 from World Development Indicator 2017. Breusch-Pagan, Honda, King-Wu, Standardized Honda and Standardized King-Wu Lagrange Multiplier test are used to test the random effects on pooled OLS model. Hausman test is used to select the appropriate model between fixed effect and random effect model. Breusch-Pagan LM, Pesaran LM and Baltagi, Kao and Feng bias corrected scaled test are performed to check the cross-sectional dependence of the residuals. Panel Corrected Standard Error (PCSE) model has been used to deal with contemporaneous correlation in residuals. In this study health expenditure per capita and food production index are used as economic factors, education and access to improved water facilities are used as social factors and urbanization is used environmental factors. Empirical results reveal that health expenditure per capita, education, access to improved water sources and urbanization have statistical significant positive impact on life expectancy, but the impact of food production index is found statistically significantly negative in the south Asian countries. The findings of this study help the policy makers to take a suitable policy for extending life expectancy in the South Asian countries.","PeriodicalId":298738,"journal":{"name":"international journal of research in computer application & management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
