We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...

Keywords: Inverse coefficient problem (ICP) Lie-group adaptive method (LGAM) Leading coefficient Inverse Sturm–Liouville operator Iterative method a b s t r a c t We consider an inverse problem for identifying a leading coefficient a(x) in À(a(x)y 0 (x)) 0 + q(x)y(x) = H(x), which is known as an inverse coefficient problem for the Sturm–Liouville operator. We transform y(x) to u(x, t) = (1 + t)...

There are two biological systems available for removing phosphorus from waste water, conventional phosphorus removal (CPR) and denitrifying phosphorus removal (DPR) systems, and each is characterized by the type of sludge used in the process. In this study, we compared the characteristics associated with the efficiency of carbon utilization between CPR and DPR sludge using acetate as a carbon s...

the course of consecutive experiments in this report aimed to a research or introductory identification about mechanical and acoustical properties of maple (acer velutinum) wood. studied factors were included quality factor (due to internal friction), acoustic coefficient, acoustical conversion efficiency as well as the modulus of elasticity (young’s modulus) which they were all accomplished us...

ERP implementations have the potential of significantly complementing the use of business-to-business e-commerce technologies. We consider the sources of this complement by drawing on transaction cost economics, the resource-based view of the firm and the theory of swift even flow. Analysis of 115 firms shows that perceived transactional efficiencies are greater for B2B e-commerce technologies ...

Citizens interact with government agencies through a variety of channels, e.g., front desk, telephone, website and e-mail. Regardless of these possibilities, they prefer the traditional channels like the front desk. Government agencies strive for a balance between service delivery resulting in customer satisfaction and cost efficiency in their operations. Through better use of the online servic...

The establishment of trust in e-government information security is of prominent importance for the full use of the actual potential of e-government. In this article, the trust creation mechanism to e-government information security is analyzed, and the model for the assessment of trust is suggested. The model is based on integration of reputation values calculated according to trust data collec...
