The earliest descriptions of multiple sclerosis (MS) rarely distinguished cognitive impairment from the general category of "mental symptoms", which also encompassed a broad range of affective disorders. Case-study methods led to disputes about the extent and nature of these symptoms, exacerbated by different national medical traditions. Appropriate scientific methods were only used to investigate cognitive performance in a modest number of studies up to the 1960s, and it was being argued as late as the mid 1970s that affective processes rather than cognitive processes were the key to understanding the psychological aspects of MS. However, the early 1980s, saw major developments in test procedures for the detection of subtle and selective cognitive changes, in the use of brain imaging techniques, and in collaboration between neurologists and neuropsychologists. Pressure to use research findings to improve patients' daily lives suggests a need to reconsider the connection between affective and cognitive processes in MS.
Vagrants were everywhere in Victorian culture. They wandered through novels and newspapers, photographs, poems and periodicals, oil paintings and illustrations. They appeared in a variety of forms in a variety of places: Gypsies and hawkers tramped the country, casual paupers and loafers lingered in the city, and vagabonds and beachcombers roved the colonial frontiers. Uncovering the rich Victorian taxonomy of nineteenth-century vagrancy for the first time, this interdisciplinary study examines how assumptions about class, gender, race and environment shaped a series of distinct vagrant types. At the same time it broaches new ground by demonstrating that rural and urban conceptions of vagrancy were repurposed in colonial contexts. Representational strategies circulated globally as well as locally, and were used to articulate shifting fantasies and anxieties about mobility, poverty and homelessness. These are traced through an extensive corpus of canonical, ephemeral and popular texts as well as a variety of visual forms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
