BACKGROUND Our aim was to explore the technical efficiency (TE) of the Iranian rural primary healthcare (PHC) system for diabetes treatment coverage rate using the stochastic frontier analysis (SFA) as well as to examine the strength and significance of the effect of human resources density on diabetes treatment. METHODS In the SFA model diabetes treatment coverage rate, as a output, is a fun...
Background and Objectives: Health insurance would guarantee people security against disease and health problems. Given the key role of health insurance in achieving the goals of justice and reducing the out-of-pocket payment, this study aimed to evaluate the performance of Iran health insurance using the DEA model in 2014. Methods: This was a cross sectional study. The study population inclu...
The optimal hybridization of photovoltaic (PV) and thermoelectric (TE) devices has long been considered ideal for the efficient harnessing solar energy. Our hybrid approach uses full spectrum solar energy via lossless coupling between PV and TE devices while collecting waste energy from thermalization and transmission losses from PV devices. Achieving lossless coupling makes the power output fr...
The main objective of the present study is to analyze the effects of agricultural crop insurance on farmers’ technical efficiency and risk attitude. Required data came from questionnaires that were completed by the Institute for Planning and Agricultural Economics of the Ministry of Agriculture. Farmers’ technical efficiency and attitude toward risk were estimated using stochastic frontier prod...
Application of DEA and SFA on the Measurement of Agricultural Technical Efficiency in MENA Countries
The purpose of this paper is to investigate the levels of technical efficiency in agricultural sector of MENA countries by using Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) approaches in 2007-2008. The results show that the total average of technical efficiency is as follows: DEABCC(0.770)>DEACCR(0.744)>SFA(0.479), and among all MENA countries, the best performanc...
Direct conversion of heat into electricity through advanced thermoelectric (TE) materials has been one of the most attractive solutions to the severe environmental and energy issues facing humanity. In recent years, great progress has been made in improving their dimensionless figure of merit (ZT), which determines the conversion efficiency of TE devices. ZT is related to three “interlocked” fa...
Introduction : The recognition of economics of hospitals, as integral and costly components of health care systems, is vital for assessing their efficiency and the factors affecting them. The study through Data Envelopment Analysis (DEA) aimed to determine the efficiency of selected hospitals of Urmia University of Medical Sciences. Methods : This was a descriptive-analytic (cross-sectional...
In this research, efficiency of Iranian forest and rangeland decision making unit was assessed using non-parametric method. Inputs and outputs determined by field research and with applying a Delphi method the final input and output variables selected. Forty five wood-producing units (forestry plans) in three northern Iranian province were studied using Data Envelopment Analysis. The efficiency...
This study intends to estimate bias corrected efficiency, technical efficiency, managerial efficiency and thus scale and confidence intervals associated with them, using input oriented data envelopment analysis approach and LSW algorithm. Results show the average of scale efficiency of our country’s industry section is 93% and except for recycling industry (code no. 37), furniture and unclassif...
Leaf internal, or mesophyll, conductance to CO(2) (g(m)) is a significant and variable limitation of photosynthesis that also affects leaf transpiration efficiency (TE). Genotypic variation in g(m) and the effect of g(m) on TE were assessed in six barley genotypes (four Hordeum vulgare and two H. bulbosum). Significant variation in g(m) was found between genotypes, and was correlated with photo...
