OBJECTIVE The objective of this study was to examine the association of cigarette smoking and weight concerns in adolescents, given that adolescents may begin smoking or have difficulty quitting because of their expectancies of the effects of smoking on body weight. METHODS This study used data from a cross-sectional survey of 4523 Connecticut high school adolescents to assess the influence o...

The basic DEA model experiences the weights flexibility problem which is resolved by the method of weight restrictions. The current research incorporating Decision Makers’ (DMs) preferences into weight restrictions is subject to serious limitations such as lacking a framework for dual role factors and not incorporating organizational hierarchy in decision-making. The proposed Genetic Algorithm ...

I t is shown t h a t in the r t h order binary Reed-Muller code of length N = 2" and m i n i m u m distance d = 2~-L the only code-words having weight between d and 2d are those with weights of the form 2d-2 t for some i. The same result also holds for certain super-codes of the R M codes. DEFI~ITm~<. T h e weight of an integer k, W(/~), is the n u m b e r of l's in the binary expansion of ]~. ...

anorexia nervosa, which is one of the eating disorders characterized by refusing to stay at even the minimum body weight that is normal for age and height or an intense fear of gaining weight in spite of being underweight, has a higher incidence in female adolescents around their mid-twenties. it usually starts with exerting voluntary restrictions in eating, but obsessive- compulsive behaviors ...

A characteristic of data envelopment analysis (DEA) is to allow individual decision making units (DMUs) to select the factor weights that are the most advantages for them in calculating their efficiency scores. This flexibility in selecting the weights, on the other hand, deters the comparison among DMUs on a common base. For dealing with this difficulty and assessing all the DMUs on the same s...
