Study of rotation curves of spiral galaxies with a scalar field dark matter model

In this work we study rotation curves of spiral galaxies using a model of dark matter based on a scalar-tensor theory of gravity. We show how to estimate the scalar field dark matter parameters using a sample of observed rotation curves.Comment: 6 pages, 2 figures. arXiv admin note: substantial text overlap with arXiv:1112.520

Public libraries and the unemployed in Sheffield, United Kingdom: Comparison between Internet search engines and gateways

This paper, "Public libraries and the unemployed in Sheffield, United Kingdom: Comparison between Internet search engines and gateways" is part of a bigger research paper for the doctoral module of Research Training Program, RTP: GSC6100: Library and Info Skills for Successful Research The Assessment Portfolio, at my PhD Program in Information Studies at the University of Sheffield, UK. The module coordinator was Mr. Alastair Allan and Ms. V.A. Harding, both librarians at the University of Sheffield Library

Do Unprejudiced Societies Need Equal Opportunity Legislation?

To what extent should banks, insurance companies and employers be allowed to use personal information about the people whom they lend to, insure or employ in setting the terms of the contract? Even when different treatment is motivated by profit not prejudice, banning discrimination (when combined with mandatory protection against failure) may well be the best way of effecting redistribution of income. Unlike income taxation, this policy achieves its goals without much adverse effect on incentives. Public provision of low-powered incentive contracts issued on generous terms is also a potent instrument of efficient redistribution. This is true even if the government cannot observe type but the private sector can.equal opportunities, incentive contracts, asymmetric information, distribution
