transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. radial artery pseudoaneurysms present as a rare complication of transradial catheterization. although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the tr band ® (terumo medical corporation, somerset, nj) is a ...

We consider the decision problem of making causal conclusions from observational data. Typically, using standard matched pairs techniques, there is a source of uncertainty that is not usually quantified, namely the uncertainty due to the choice of the experimenter: two different reasonable experimenters can easily have opposite results. In this work we present an alternative to the standard non...

An environmental impact assessment is an assessment of the possible positive or negative impact that a proposed project may have on the environment, together consisting of the natural, social and economic aspects.  Environmental Impact Assessment (EIA) of Masjid-I-Sulaiman desalination and operating unit’s project in the southern of Iran using Rapid Impact Assessment Matrix (RIAM) method is pre...

The performance of an organization is a function of its efficiency and effectiveness. Efficiency is the degree to which inputs are used to produce outputs. Effectiveness is the degree to which organizational goals are met. Efficiency provides a starting point for our discussion, as it continues to be an active area of research. Efficiency is defined as the ratio of total output to total input. ...

The present study investigates the linear and nonlinear causal linkages in exchange, equity and derivatives markets. Specifically, in case of exchange markets, among six currencies denoted relative to United States dollar (USD), namely EUR, GBP, JPY, CHF, AUD and CAD. The prime motivation for choosing these exchange rates comes from the fact that they are the most liquid and widely traded, cove...

This article presents an empirical banking application illustrating the use of a nonparametric frontier model relying on a probabilistic definition of the production frontier. It investigates the statistical significance of nonperforming loans in productive efficiency for a sample of Brazilian banks using the concepts of conditional and unconditional efficiency measures in a context where it is...

In this paper, a novel prediction based mean-variance (PBMV) model has been proposed, as an alternative to the conventional Markowitz mean-variance model, to solve the constrained portfolio optimization problem. In the Markowitz mean-variance model, the expected future return is taken as the mean of the past returns, which is incorrect. In the proposed model, first the expected future returns a...
