Aboriginal intra-urban mobility in Katherine, Northern Territory
Very little is known about the movements of Aboriginal people within North Australian towns. This is partly due to a lack of adequate census data with which to measure intra-urban mobility but also reflects an enduring research interest in town camps to the relative exclusion of other arenas of Aboriginal urban existence. This paper presents some brief descriptive data from one Northern town which highlights the existence of Aboriginal population movement between housing sectors and provides an indication of the magnitude and direction of flows. A simple descriptive model of Aboriginal urban settlement is proposed as a basis for comparison with mobility patterns in other urban settings.
Alice through the Looking Glass: Marginalisation in the Aboriginal Town Camps of Alice Springs
This paper was written immediately following an extensive period of fieldwork in the small Australian town of Alice Springs. It was deliberately written before most of the statistical results of various surveys were available in order to crystallise the less quantifiable impressions and features of the Aboriginal position in the town around a conceptual framework of societal relations. The few studies of urban Aborigines to date have been more descriptive than analytical. To this end, and based upon my own previous field experiences, I have borrowed from contemporary Third World studies the notions of marginality and marginalisation, and assessed the situation in Alice Springs in these terms. The reasons for this particular choice of concepts was partly because of the location of Alice Springs in ‘colonial’ Australia but primarily because of the etymological and philosophical links with the prevailing opinion of most Aborigines in Alice Springs as fringe dwellers—people on the margins of the town and its society. There have been few attempts to examine the position of Aborigines in contemporary Australia in conceptual terms and this effort will undoubtedly have many shortcomings. However, its purpose is not to be definitive but rather to stimulate further investigation and discussion.
Early Stage Diagnosis of Parkinson’s Disease Using HOS Features of EEG Signals
Parkinson’s disease (PD) is a common neurodegenerative disease that causes involuntary muscle movements and tremor among other symptoms. One approach to diagnosing this disease is by analyzing the electroencephalography (EEG) signals of the patients. However, due to the complexity of this type of signal, more advanced feature extraction and classification methods are required. The goal of this study is to combine six well-known features in EEG analysis with eight higher order statistical features and use them for classification of early stage PD (1st and 2nd stage) from a healthy control group. After extracting the required features, eight classifiers are employed to classify the signals.
