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 ...

Multi-attribute decision problems with uncertainty largely exist in the real world, it is very necessary to solve these problems. The paper proposes a grey correlation method based on maximizing deviation to solve the multiple attribute decision-making problems under risk in which the weight is unknown and attribute values are interval numbers. In the grey correlation method, according to diffe...

Previous studies, conducted mainly in Asian countries, have shown that women‘s empowerment is associated with contraceptive use, lower fertility, and longer birth intervals. Yet little is known about the association of women‘s empowerment with fertility desires in subSaharan African countries where overall fertility levels remain high. This study tries to fill this gap, exploring whether women‘...

Exploiting the analogy between exemplar models and population coding schemes, we characterize, by means of information theoretic tools, the efficiency of a large but finite population of cells coding for a discrete set of categories (e.g. vowels). The optimal code is shown to typically allocate more cells to class boundaries than to regions further apart. We then discuss the predicted perceptua...

We consider the problem of designing reliable and confidential lattice codes, known as wiretap lattice codes, for fast fading channels. We identify as code design criterion for finite lattice constellations a finite sum of inverse of algebraic norms, in fact the analogous for finite sums of the known criterion for infinite constellations, which motivates us to study totally real number fields w...

Pregnancy and delivery is one of the main causes in the female body weight alteration, especially with obesity. This alteration in body weight has a significant effect not only for a femine beauty standpoint, but also for more important reproductive functions in postpartum. For the actual condition of the maternal body weight alteration and its clinical significance, we made the various analysi...

Today, organizations rely on decision makers to produce “mission critical” decisions that are based on inputs from multiple domains. The ideal decision maker has a profound understanding of specific domains, coupled with the experience that allows them to act quickly and decisively on the information. Daily they face problems and failures that are too difficult for any individual person to solv...

Grand Rationality is dead, long live Reason! The 1960's saw the heydays of Grand Rationality in social decision-making. The planning ideal of that period has been termed " comprehensive rational approach " (Benveniste, 1989), " design school " (Mintzberg, 1994), or " technical rationality " (Schön, 1991). That ideal of rationality crumbled, much due to its inherent weaknesses. Is there at prese...
