Spatialities of Globalisation

Abstract: The focus of this paper is on the theorisation of the spatialities of globalisation. I seek to shift the emphasis away from the currently dominant discourse of scalar and territorial relativisation, towards relational processes and network forms of organisation that defy a linear distinction between place and space. I stress the importance of actor networks of varying length and duration as well as the world of practices as the central components of a topographical understanding of globalisation. What this might mean in terms of a theorisation of place is illustrated through a discussion of the geography of the urban economy and a discussion of the politics of place.

Holography, thermodynamics, and fluctuations of charged AdS black holes

Abstract: The physical properties of Reissner-Nordstrom black holes in (n11)-dimensional anti-de Sitter spacetime are related, by a holographic map, to the physics of a class of n-dimensional field theories coupled to a background global current. Motivated by that fact, and the recent observations of the striking similarity between the thermodynamic phase structure of these black holes ~in the canonical ensemble! and that of the van der Waals-Maxwell liquid-gas system, we explore the physics in more detail. We study fluctuations and stability within the equilibrium thermodynamics, examining the specific heats and electrical permittivity of the holes, and consider the analogue of the Clayperon equation at the phase boundaries. Consequently, we refine the phase diagrams in the canonical and grand canonical ensembles. We study the interesting physics in the neighborhood of the critical point in the canonical ensemble. There is a second order phase transition found there, and that region is characterized by a Landau-Ginzburg model with A3 potential. The holographically dual field theories provide the description of the microscopic degrees of freedom which underlie all of the thermodynamics, as can be seen by examining the form of the microscopic fluctuations. @S0556-2821~99!06820-4#

Methicillin-resistant Staphylococcus aureus: an overview of basic and clinical research.

Abstract: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most successful modern pathogens. The same organism that lives as a commensal and is transmitted in both health-care and community settings is also a leading cause of bacteraemia, endocarditis, skin and soft tissue infections, bone and joint infections and hospital-acquired infections. Genetically diverse, the epidemiology of MRSA is primarily characterized by the serial emergence of epidemic strains. Although its incidence has recently declined in some regions, MRSA still poses a formidable clinical threat, with persistently high morbidity and mortality. Successful treatment remains challenging and requires the evaluation of both novel antimicrobials and adjunctive aspects of care, such as infectious disease consultation, echocardiography and source control. In this Review, we provide an overview of basic and clinical MRSA research and summarize the expansive body of literature on the epidemiology, transmission, genetic diversity, evolution, surveillance and treatment of MRSA.

Precision photometry of early-type galaxies in the Coma and Virgo clusters: a test of the universality of the colour–magnitude relation – II. Analysis

Abstract: A detailed comparison of the colours of early-type galaxies in the Virgo and Coma clusters have been undertaken. The data set presented by the authors (1992, MNRAS, 254) is used to investigate the universality of the colour-magnitude correlation. This work reassesses the anomaly noted by Aaronson, Persson & Frogel (1981, ApJ, 245). Following these authors, we initially compare the relative distances of the two clusters derived from the L-σ and U-V and V-K colour-magnitude correlations. However, in contrast to their result, we find that all three relations give compatible relative distance moduli. A similar result is found by correlating the colours and velocity dispersions with photometric diameters

Verbal and Visuospatial Short-Term and Working Memory in Children: Are They Separable?

Abstract: This study explored the structure of verbal and visuospatial short-term and working memory in children between ages 4 and 11 years. Multiple tasks measuring 4 different memory components were used to capture the cognitive processes underlying working memory. Confirmatory factor analyses indicated that the processing component of working memory tasks was supported by a common resource pool, while storage aspects depend on domain-specific verbal and visuospatial resources. This model is largely stable across this developmental period, although some evidence exists that the links between the domain-specific visuospatial construct and the domain-general processing construct were higher in the 4- to- 6-year age group. The data also suggest that all working memory components are in place by 4 years of age.
