This study analyzes the efficiency of small and medium-sized enterprises (SMEs) of a national technology innovation research and development (R&D) program. In particular, an empirical analysis is presented that aims to answer the following question: "Is there a difference in the efficiency between R&D collaboration types and between government R&D subsidy sizes?" Methodologically, the efficienc...
The computer industry plays an important role in promoting the development of national economy and national comprehensive power of China. As an important evaluation indicator, the R&D efficiency of computer industry becomes one of the most important research fields currently. According to the shortages of traditional C2R model of DEA, this paper constructs an improved DEA model for measuring th...
Diethanolamine-Induced Alteration of Hepatic Mitochondrial Function and Structure. BARBEE, S. J., AND HARTUNG, R. (1979). Toxicol. Appl. Pharmacol. 47,431-440. Diethanolamine (DEA) has been shown to interfere with phospholipid metabolism. It was hypothesized that DEA may alter membrane-bound biochemical processes which are dependent upon phospholipids. DEA was investigated for its effect on hep...
In many organizations and financial institutions, we don't always have acsses to inputs and outputs to evaluate the decision-making units (DMUs), but rather only a ratio of inputs to outputs ( or reverse) might be available. In DEA, cost efficiency determines input standards based on input costs. In multi-stage network DEA processes, in addition to input standards, cost efficiency would determi...
This study presents data envelopment analysis (DEA)-based systematic and simultaneous performance measures for research and business development (R&BD) and internal processes. In particular, we focus on the relationship between the research and development (R&D) process and business development (BD) process in evaluating R&BD overall performance, and provide effective guidelines for relatively ...
Riparian zones are recognized as landscape features that buffer streams from pollutants, particularly nitrogen. The objectives of this experiment were to (i) assess denitrification activity within a riparian zone and (ii) determine the influence of physical, chemical, and landscape features on denitrification. This experiment was conducted from 1994 to 1997 in North Carolina on a riparian zone ...
The Effect of Diethanolamine on Hepatic and Renal Phospholipid Metabolism in the Rat. BARBEE, S. J., AND HARTUNG, R. (1979). Toxicol. Appl. Pharmacol. 47,421430. DEA inhibited the in vitro synthesis of both phosphatidyl choline and phosphatidyl ethanolamine in liver tissue. In each caSe the K, was approximately 3 mu DEA. DEA inhibited the formation of phosphatidyl choline competitively, and pro...
Malmquist Productivity Index (MPI) is a numeric index that is of great importance in measuring productivity and its changes. In recent years, tools like DEA have been utilized for determining MPI. In the present paper, some models are recommended for calculating MPI when there are just ratio data available. Then, using DEA and DEA-R, some models are proposed under the constant returns to scale ...
Inthis article we offer a method of ranking contractors by using DEA based onanalysis deficit and AHP. The process of hierarchical analysis (AHP) byproviding scales from paired comparison matrix, performs the contractor’sprioritizing choice. But AHP has some problems and to solve those problems,Jahanshahloo and his colleagues presented a new model which uses DEA andstandard deviation. In this a...
In this article, centralized resource allocation (CRA) models based on the value efficiency in DEA and DEA-R are recommended. In general, if the input and output data of decision-making units are available, DEA models provide targets of units on the efficiency frontier in addition to the efficiency of units. However, if only a ratio of the input data to output data, or vice versa, is available,...
