Geographically touring the eastern bloc: British geography, travel cultures and the Cold War

This paper considers the role of travel in the generation of geographical knowledge of the eastern bloc by British geographers. Based on oral history and surveys of published work, the paper examines the roles of three kinds of travel experience: individual private travels, tours via state tourist agencies, and tours by academic delegations. Examples are drawn from across the eastern bloc, including the USSR, Poland, Romania, East Germany and Albania. The relationship between travel and publication is addressed, notably within textbooks, and in the Geographical Magazine. The study argues for the extension of accounts of cultures of geographical travel, and seeks to supplement the existing historiography of Cold War geography

Criminalidade organizada nas prisões e os ataques do PCC

The advent of organized crime in Brazilian prisons, especially in the state of São Paulo, constitutes the object of this article. The waves of attack unleashed by the Capital's First Command (PCC - Primeiro Comando da Capital), in May 2006, which resulted in countless deaths, brought cities to a halt, and cornered authorities in charge preventing them from applying law and order are the starting as well as reference points taken. The advent of organized criminality is analyzed under the light of determined axes: the international scenario and the Brazilian context, the historical antecedents, the taking root of crime in society and the role of penitentiary public policies.A emergência da criminalidade organizada nas prisões brasileiras, em especial no Estado de São Paulo, constitui objeto deste artigo. Tomam-se como ponto de partida e referência para análise as ondas de ataques desencadeadas pelo Primeiro Comando da Capital (PCC), de maio a agosto de 2006, que resultaram em inúmeros mortos, paralisaram cidades e acuaram as autoridades encarregadas de aplicar lei e ordem. A emergência da criminalidade organizada é analisada sob eixos determinados: cenário internacional e contexto brasileiro, antecedentes históricos, enraizamento do crime na sociedade e papel das políticas públicas penitenciárias

Objectification and Quantification of the Cognitive Impairment from an Existing HIV Infection or HIV Encephalopathy Using Magnetic Resonance Spectroscopy

Some patients with HIV develop dementia. Using in vivo proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy, it is possible to measure the metabolic changes noninvasively. In this study, it is of interest to answer the clinically relevant question of whether magnetic resonance spectroscopy is suitable for the diagnosis of HIV encephalopathy. In total, 14 HIV-positive patients were investigated by means of localized 1 H-NMR spectroscopy in the following locations: (1) the mid-parietal gray matter, (2) the parietal white matter (PWM), and (3) the frontal white matter. All patients had no other brain diseases, apart from the HIV encephalopathy. The clinical extent of HIV encephalopathy of each patient was investigated using the following tests: (1) an electroencephalogram, (2) a neurological examination and psychiatric assessment, and (3) a psychometrical test. The spectroscopic changes in the PWM were more pronounced than those in the cortex, and the myo-inositol/creatine (mI/Cr) signal showed a clear increase in the cortex. Overall, the mI/Cr ratio emerged as the most reliable and earliest parameter to indicate an HIV encephalopathy
