Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Analysis of overall technical efficiency, pure technical efficiency and scale efficiency in the medium-sized audit firms

Expert Systems With Applications, 2009
This study uses the data envelopment analysis (DEA) to evaluate the operational efficiency of 173 medium-sized audit firms in 2005. The empirical result indicates that there are 24 audit firms with the overall technical efficiency value of 1. In terms of overall technical efficiency, pure technical efficiency and scale efficiency, the result shows that

The Structure of Technical Efficiency

The Scandinavian Journal of Economics, 1983
It is common practice to decompose measures of efficiency into component measures of technical and allocative efficiency. In this paper we show how, and why, to decompose a general measure of technical efficiency into component measures of purely technical efficiency, congestion, and scale efficiency, and we investigate the properties of each measure ...

Measures of technical efficiency [PDF]

open access: possibleJournal of Economic Theory, 1985
\textit{R. Färe} and \textit{C. A. K. Lovell} [ibid. 19, 150-162 (1978; Zbl 0398.90012)] suggest four properties that a measure of technical efficiency should satisfy; the commonly employed Debreu-Farrell measure fails three of them. Necessary and sufficient conditions for a measure to satisfy the four conditions are provided and recently proposed ...

X-efficiency and technical efficiency

Public Choice, 1994
Efficiency measurement has become a very popular field in applied economics in recent years, and with this interest there has been a large intellectual investment in refining the empirical methods available to researchers in the area. In this paper we relate these developments to Harvey Leibenstein's original 1966 insight into the psychological ideas ...

Institutions, Freedom, and Technical Efficiency

Southern Economic Journal, 2002
The impact of institutions on economic performance is currently the subject of much research. In this study we use panel data to estimate a stochastic production frontier and the sources of inefficiency for a broad set of countries. A maximum‐likelihood procedure is used to estimate the parameters for the stochastic production frontier and the ...
