quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. this study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in gorgan city. cross-section survey data were gathered...

The set of Cobb-Douglas production functions is usually fitted by first linearizing the models through logarithmic transformation and then applying method of least squares. However, this procedure is valid only when the underlying assumption of multiplicative error-terms is justified. Unfortunately, this assumption is rarely satisfied in practice and accordingly, the results obtained are of dou...

This article identifies two factors that contribute to the recycling of deficit pedagogy in programs designed for what Rose calls "students on the bounda1y." The first factor is traditional, technocratic definitions of literacy, viewed here as a mechanism for importing deficit theories into the content of instructional programs and accounting partially for the "missed" education of marginalized...

BACKGROUND Chêneau-Brace treatment of a certain standard reduces the rate of surgery, prevents progression and in a certain patient population leads to marked improvement of Cobb angle and cosmetic appearance. During the last two years a patient refusing surgery with a double major curvature of initially 60 degrees showed a clear cosmetic improvement and a clear radiological progression at the ...

In this paper a re-examination of the original time-series data sets used by Professor Douglas and associated researchers to establish the existence of an aggregate production function is undertaken. Particular attention is paid to the issue of whether the data provide deductive support for the ‘Laws of Production’ as claimed by Douglas (1948). Various statistical methods are used to analyse th...

This study aims to determine the factors that affect income of soybean farming. research was conducted in Kulon Progo Regency with number respondents as many 50 farmers. uses Cobb-Douglas profit function technique Unit Output Price or UOP Cobb Douglas Profit Function ( UOP-CDPF). has been declared valid, reliable, data is normally distributed, free from multicollinearity and heteroscedasticity ...

The current paper examines the cross-efficiency concept in data envelopment analysis (DEA). While cross-efficiency has appeal as a peer evaluation approach, it is often the subject of criticism, due mainly to the use of DEA weights that are often non-unique. As a result, cross-efficiency scores are routinely viewed as arbitrary in that they depend on a particular set of optimal DEA weights gene...
