data envelopment analysis (dea) is a branch of management, concerned with evaluating the performances of homogeneous decision making units (dmus). the performances of dmus are affected by the amount of sources that dmus used. usually increases in inputs cause increases in outputs. however, there are situations where increase in one or more inputs generate a reduction in one or more outputs. in ...

The paper illustrates how decision makers may have an incentive to withhold information regarding the existence of Pareto improving collective actions. The resulting level of inefficiency varies with the way compromises are reached when the parties have to choose among multiple options. Various reasonable compromise rules can be ranked unequivocally, and a rule resulting in a minimal level of i...

Since Briec developed a family of the least distance based inefficiency measures satisfying weak monotonicity over weakly efficient frontier, the existence of a least distance based efficiency measure satisfying strong monotonicity on the strongly efficient frontier is still an open problem. This paper gives a negative answer to the open problem and its relaxed open problem. Modifying Briec’s i...

As public intervention is a pervasive influence on food prices, this paper asks whether and how the inefficiency of state institutions matters to food prices. In the context of the wheat subsidy scheme in India, the paper models the implications of quality differences between public and private grain supply. As both are procured at similar prices, the lower quality of public grain marks the ine...

Recent studies revealed that some social and technological network formations can be represented by the network formation games played by selfish multiple agents. In general, the topologies formed by selfish multiple agents are worse than or equal to those formed by the centralized designer in the sense of social total welfare. Several works such as the price of anarchy are known as a measure f...

cytomegalovirus (cmv) infection can cause colitis which is usually manifested with fever, weight loss, anorexia and abdominal pain.watery diarrhea can be the only manifestation. cmv colitis usually can not be diagnosed according to the clinical findings. moreover, endoscopic appearance can exactly mimic pseudo-membranous colitis. here by, we are presenting a patient with fever and watery diarrh...

objective(s):this study aims at exploring cytotoxic activity of different peptides derived from vsvg protein against mcf-7 and mda-mb-231 breast cancer cell lines and human embryonic kidney normal cell (hek 293).    materials and methods: the anticp web server was used to predict anticancer peptides. the cytotoxic activity of peptides with high score (p26, p7) and low score (p19) was examined b...
