More than thirty years ago, Charnes, Cooper and Schinnar (1976) established an enlightening contact between economic production functions (epfs) — a cornerstone of neoclassical economics — and information theory, showing how a generalization of the Cobb-Douglas production function encodes homogeneous functions. As expected by Charnes et al., the contact turns out to be much broader: we show how...

[Purpose] The purpose of this study was to compare the effect of Schroth and Pilates exercises on the Cobb angle and body weight distribution of patients with idiopathic scoliosis. [Subjects] Twenty-four scoliosis patients with a Cobb angle of ≥20° were divided into the Schroth exercise group (SEG, n = 12) and the Pilates exercise group (PEG, n = 12). [Methods] The SEG and PEG performed Schroth...

[Purpose] The purpose of this study was to examine whether chiropractic techniques would reduce the curvature of idiopathic scoliosis, which commonly occurs in elementary school children. [Subjects] The subjects of this study were 5 healthy elementary students who listened to an explanation of the study methods and purpose of the study and agreed to participate in the experiment. [Methods] The ...

Methods Nine AIS patients undergoing casting for new braces participated in this pilot study (2 males, 7 females, aged 11-16, Cobb angles 16-44 degrees). An ultrasound scan was used to measure the patient’s (baseline) Cobb angle. The orthotist then used a custom standing Providence system to apply corrective pressures simulating a brace. A second ultrasound scan measured the new (corrected) Cob...

the effect of feeding different protein profiles on growth performance, carcass components and nitrogen content of litter in cobb 500 broiler strain was evaluated using 800 chicks in a completely randomized design with four treatments, five replicates groups of 40 birds per each treatment. the treatments were consisted of four protein feeding profiles (based on cobb strain nutrition guide, reco...

A common theme in the theory of demand aggregation is that market demand can acquire properties which are not always individually present among the agents who make up that market, a phenomenon we call heterosis in this paper. This paper focusses on the well known result that with a suitable distribution of demand behavior (arising perhaps from the underlying distribution of preferences), market...
