data envelopment analysis (dea) is an efficient method to perform evaluation of units. in dea we try to evaluate units with undesirable factors in input & outputs by satisfaction function, testing some models. on the other hand benefiting this concept, we can identify non-efficient units. also we can recognize why these units are inefficient and calculate the reason of their inefficiency and ho...

INTRODUCTION Few treatments are available that can safely and effectively stimulate new platelet production for thrombocytopenic patients. Additionally, recipients of transfused platelets may experience an inflammatory response due to stored platelets becoming unnecessarily activated, thus creating the need for suitable agents that will dampen undesirable platelet activation. We investigated th...

Different from traditional efficiency research and previous studies considering undesirable outputs, this paper proposes models which distinguish weak and strong disposability features among various undesirable outputs based on the technical nature of the undesirable outputs. The paper illustrates the approach using a research sample covering 582 base-load Chinese coal-fired power plants in 200...

Results indicated that the undesirable traits of one gender were negatively correlated with the desirable traits of the opposite gender. Desirable masculinity predicted psychological well-be...
