Introduction: Heat is one of the hazardous physical agents in the workplace. Exposure to heat and consequent thermal stress influence workers productivity in addition to adverse health effects. The aim of this study was to determine the heat stress induced productivity loss related to different tasks of farmers in Darreh Shahr city, during summer. . Material and Method: This cross-sectional stu...
to calculate partial and total productivity of production factors in broiler farms in yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. to measure productivity, the cobb-douglas production function was estimated using classic and fuzzy regression met...
in this study, total factor productivity growth of iran’s pulses (including irrigated pea, dry pea, irrigated lentil, dry lentil, irrigated soybean, dry soybean and irrigated bean) during of farming years 1989-1990 though 2007-2008 had been analyzed, using nonparametric malmquist approach. so, amounts of inputs usages include seeds, fertilizers, dung, poison, herbicide, labor, water and acreage...
This paper is a survey of recent contributions to and developments in the relationship between efficiency and productivity via the production function. The objective is to provide a brief discussion on data and on the methods of measuring efficiency and productivity. First, we introduce the reader to the measurement of partial and total factor productivity in the context of static and firm - sp...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
The present study used different categories of organized sector manufacturing industries pooled data for the periods of 1981-82 and 2007-08 in Haryana state (India). The present undertaking seeks to analyze the inter-temporal and inter-industry comparison of total factor productivity (TFP) measured by Malmquist productivity index - an application of DEA which calculates the indices of TFP and i...
The purpose of this article was to estimate the effect of higher education on total productivity changes and technical efficiency in the 4-digit classification code of ISIC in Iran during the period of 1994-04. In this regard, a two-way stage approach was used. In the first stage, Malmquist Productivity Index (MPI) and technical efficiency index by Data Envelopment Analysis (DEA) and Stochastic...
