Representation and identity - convergence of brain research and mind-brain philosophy

The localization or representation of mental abilities in the brain have always been considered as key questions for understanding the organization of the human nervous system. Particularly with the advent of modern electrophysiological and imaging techniques that provide maps of electromagnetic fields and metabolic processes on the living central nervous system, the representation theory is experiencing a scientific renaissance in neurology, but is only one theory, however, in the succession of a long philosophical tradition dealing with the possible identification of mental phenomena and brain processes. This dichotomy was formulated at the latest in the Cartesian dualism of res cogitans and res extensa of the mind-body problem. Nowadays philosophical discussion, on the contrary, is dominated by monistic concepts that attempt to explain the mental realm on an organic foundation in order not to succumb to the problem of a psychophysical dualism. Of these, the identity theory offers a philosophically plausible concept postulating that the identity of brain conditions and mental phenomena is based on organic foundations. In this theory, the efforts of brain research converge on the representations of mental phenomena in the human nervous system. In a comprehensive approach, both concepts could complement each other.

Random Time Sampling

Random Time Sampling is an innovative data collection method which has potential for adaptation and use by geographers. Individual pocket-sized programmable beepers were used in a pilot study of the uses of time by older households and older people's attitudes to different activities. Random beeps were used to prompt individuals living in eleven Melbourne suburbs to record time use data in diaries over a period of a week. The method proved extremely effective and reliable, and many participants reporting that they enjoyed the exercise.     

Morphological Impacts and Implications of a Trial Release on the Wingecarribee River,New South Wales

A trial, monitored release on the Wingecarribee River over 27 days had a peak discharge below the Wingecarribee Dam of 1090 ML/d, which had a flow duration of 0.95 per cent. Morphological impacts on 29 km of channel below the dam included bank erosion, concentrated neck overflow, bed degradation and channel widening at recent cutoffs, sedimentation in weir pools and overbank flow, particularly at discharges greater than 800 ML/d. Prolonged operational releases at bankfull discharge (400–800 ML/d) will have the greatest morphologic impacts and should be avoided. Pulses which dissipate stream power over a broad, well-vegetated floodplain should be incorporated in the operational release policy, provided such pulses are phased to facilitate channel and vegetation recovery.     

Origin and Collapse of Complex Societies in Oaxaca (Mexico): Evaluating the Era from 1965 to the Present

I summarize recent archaeological work in Oaxaca, Mexico, with a focus on questions central to world prehistory: the origin and collapse of complex societies. Monte Albán was the capital of an emerging civilization in the southern highlands of Mexico during the second half of the first millennium B.C. Soon after the foundation of the ancient city, there is evidence for state formation and a political expansion into regions outside the Valley of Oaxaca. Centuries later, Monte Albán went into decline, giving way to the competing small polities found throughout Oaxaca at the time of the Spanish conquest. Since the late 1960s, our knowledge of these changes has been transformed by study of Oaxaca's pre–Monte Albán past, regional settlement surveys, and processual model building. Evolutionary and historical perspectives allow for significant refinement of current debates surrounding the rise and fall of complex societies in Oaxaca.     

Race,Gender, Science and Citizenship

This paper argues that the history of embodiment of human racial and gendered differences must be seen as part of the history of liberal citizenship and its limits. The author suggests that a science of similarity and difference can never be a reliable guide to questions of rights. The consequences of this conclusion for our understanding of science and the gendered body are addressed in the second half of the paper, in an effort to clear the way for a more adequate and inclusionary model of citizenship and rights.
