OBJECTIVES To develop a model of disease progression using multiple sclerosis (MS) as an exemplar. STUDY DESIGN AND SETTINGS Two observational cohorts, the University of Wales MS (UoWMS), UK (1976), and British Columbia MS (BCMS) database, Canada (1980), with longitudinal disability data [the Expanded Disability Status Scale (EDSS)] were used; individuals potentially eligible for MS disease-m...

We give various equivalent formulations to the (partially) open problem about Lboundedness of Bergman projections in tubes over cones. Namely, we show that such boundedness is equivalent to the duality identity between Bergman spaces, A ′ = (Ap)∗, and also to a Hardy type inequality related to the wave operator. We introduce analytic Besov spaces in tubes over cones, for which such Hardy inequa...

social life in the online world. It has become the most acceptable pattern of forging social connections on the web. Every new development has pros and cons in its own sphere, though, and social networking web sites are no different. Online social networks, being a part of the Web 2.0 world, are prone to attacks and malware infections. Social networks, such as Facebook, Twitter, MySpace, Orkut ...

To test the hypothesis that the established relationship between materialism and psychological well-being would be eliminated or significantly attenuated when controlling for social support, 159 American college students completed the Richins and Dawson (1992) materialism scale, the Cohen and Hoberman (1983) Interpersonal Support Evaluation List, and the Brief Measures of Positive and Negative ...

Lieb’s conjecture for the Wehrl entropy of Bloch coherent states is proved for spin 1 and spin 3/2. Using a geometric representation we solve the entropy integrals for states of arbitrary spin and evaluate them explicitly in the cases of spin 1, 3/2, and 2. We also give a group theoretic proof for all spin of a related inequality. c ©1999 by the author. Reproduction of this article, in its enti...

This paper uses a simple economic model of contract choice to explain the growth of sharecropping in sixteenthand seventeenthcentury France--a topic that figures in much of the social and economic history of the period. The theory turns out to fit both qualitati·ve and quantitative evidence, and although the results are as yet only preliminary, the theory does provide a better account of the sp...

the shift in the axis of development in final decade of 20th century changed its centrality from social sphere to the cultural sphere. nowadays, cultural development is a precondition to achieve other components of development and those countries that are able to achieve cultural development will be regarded successful at individual and societal levels. the present paper reviews the situation a...
