Bosonic super-WIMPs as keV-scale dark matter

Abstract: We consider models of light superweakly interacting cold dark matter, with $\mathcal{O}(10--100)\text{ }\text{ }\mathrm{keV}$ mass, focusing on bosonic candidates such as pseudoscalars and vectors. We analyze the cosmological abundance, the $\ensuremath{\gamma}$ background created by particle decays, the impact on stellar processes due to cooling, and the direct-detection capabilities in order to identify classes of models that pass all the constraints. In certain models, variants of photoelectric (or axioelectric) absorption of dark matter in direct-detection experiments can provide a sensitivity to the superweak couplings to the standard model which is superior to all existing indirect constraints. In all models studied, the annual modulation of the direct-detection signal is at the currently unobservable level of $O({10}^{\ensuremath{-}5})$.

The concepts and theories of modern democracy

Abstract: This highly acclaimed and popular academic text is now available in a new edition, having been revised and updated to cover the analyses of the use, abuse and ambiguity of many essential concepts used in political discourse and political studies These include basic concepts such as liberty, democracy, rights, representation, authority and political power New to this edition are three sections of great topical interest: entirely original analysis of global terrorism, which puts the recent developments of Islamic terrorism into perspective by comparing it with earlier examples of terrorist tactics by a variety of state agencies, revolutionary groups and minority nationalist movements extended discussion on multiculturalism, which supplements theoretical arguments with succinct summaries of the differing ways in which ethnic and cultural minorities have been dealt with in Canada, Britain, France and the Netherlands section on democratization that focuses on the problems, social and political and even theological, involved in turning authoritarian regimes into stable democracies in the Middle East and elsewhere Concepts and Theories of Modern Democracy is a stimulating guide to current world problems as well as essential reading for foundation courses at first or second year level such as elements of politics, political concepts and ideas and fundamentals in politics

Age Differences in Cognitive Performance in Later Life: Relationships to Self-Reported Health and Activity Life Style

Abstract: The predictive relationships among individual differences in self-reported physical health and activity life style and performance on an array of information processing and intellectual ability measures were examined. A sample of 484 men and women aged 55 to 86 years completed a battery of cognitive tasks measuring verbal processing time, working memory, vocabulary, verbal fluency, world knowledge, word recall, and text recall. Hierarchical regression was used to predict performance on these tasks from measures of self-reported physical health, alcohol and tobacco use, and level of participation in everyday activities. The results indicated: (a) individual differences in self-reported health and activity predicted performance on multiple cognitive measures; (b) self-reported health was more predictive of processing resource variables than knowledge-based abilities; (c) interaction effects indicated that participation in cognitively demanding activities was more highly related to performance on some measures for older adults than for middle-aged adults; and (d) age-related differences in performance on multiple measures were attenuated by partialing individual differences in self-reported health and activity.
