Brown-Séquard's theory of recovery

Charles Edouard Brown-Séquard used observation of recovered patients and experimental animals to support his theory of cerebral localization. Recovery theories assume that the nervous system is composed of one organ or many, and that each organ has one function or many. From his own studies as well as others, Brown-Séquard concluded that the brain contained at least nine separate organs, each with a single distinct function, and that each organ is organized, not as a geographically isolated cluster of neurons, but as a widely disseminated network. According to his view, function is not uniformly distributed in an organ. Focal necrosis of part of an organ temporarily inhibits the action of distant, undamaged parts; resolution of this inhibition results in recovery. Using this theory of cerebral localization and recovery, Brown-Séquard practiced an early form of scientific neurology.     

Caddoan Area archaeology since 1990

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction.     

SOIL PHOSPHATE ANALYSIS: A NEW TECHNIQUE FOR MEASUREMENT IN THE FIELD USING A TEST STRIP*

A new method for soil phosphate analysis has been developed for field measurement which will increase the applicability of phosphate mapping in archaeological prospection.     

The Practice of Identity and an Irish Sense of Place

Following in the wake of Benedict Anderson's work in particular, cultural geographers and cultural studies scholars have analyzed the nation and nationalism as primarily 'imagined' or abstract entities. Coincidentally, the greatest analytic attention has been given to nationalist representations of place, rather than to the everyday discursive practices constitutive of the nation as lived. Drawing on Pierre Bourdieu's practice theory, in this paper I develop the beginnings of a corporeal approach to the nation. Here the relationship between the practice of identity (the embodiment of gendered and sexualized subjectivities via discursive practice within culturally defined spaces) and an Irish nationalist sense of place is explored. In this approach, analytic considerations of identity and space are collapsed within the shared material and metaphoric medium of the body. Irish nationalism and the nation are analyzed as corporeal materialities via an ethnohistorical focus on late nineteenth-century changes in the political economy of 'peasant' and nationalist bodies. The analysis suggests that a particular matrix of constructions of femininity and masculinity was extended paradigmatically throughout the society in the latter half of the nineteenth century. These paradigmatic changes are characterized as a 'heterosexing' of bodies and places linked to economic change and the rise of the confessional state.     

THE APPLICATION OF ACETATE PEELS IN LITHIC USEWEAR ANALYSIS

A technique for making acetate peels of tools using Triafol is outlined. A series of ‘blind tests’ is described where the suitability of this replica material for reproducing the details of usewear was tested. The advantages and disadvantages of the use of acetate peels are discussed with reference to examination of usewear traces.     

The direction of migration: a dynamic general equilibrium model

A two-sector dynamic general equilibrium model is developed "to investigate the direction of migration in response to differing demographic and consumption demand behavior, as well as variations in production conditions." The model, which involves a rural sector and an urban sector, incorporates "returns to scale and the natural rate of sectoral population growth as important determinants of the direction of migration, in addition to price and income elasticities, and the sectoral technical change rate with which...previous studies dealt."
