Problems of participation: The limits of action research

Alvin Gouldner (1979) suggests knowledge is both culture and capital. Knowledge enables meaningful action. Capital is culture privatized. Culture is capital generalized. This raises the question of ownership in social research. Detachment in social research is praised as a virtue but also viewed as a source of difficulties epistemologically and ethically. Participatory action research offers a critique of detachment and advocates its opposite, 'commitment'. This may not necessarily involve 'political' advocacy. However, commitment to involve participants, and to further their goals through the conduct of research, does become a form of 'advocacy'. This paper draws on problematic experiences as a 'participatory action researcher' in social movement and evaluation research. Drawing on the recent work of Fuller, this paper suggests, rather bluntly, that when asked 'whose side are we on', academics might be more bold and suggest 'we are on our own side'.     

An approximate entropy test for randomness

We develop an entropy-based test for randomness of binary time series of finite length. The test uses the frequencies of contiguous blocks of different lengths. A simple condition ib the block lengths and the length of the time series enables one to estimate the entropy rate for the data, and this information is used to develop a statistic to test the hypothesis of randomness. This static measures the deviation of the estimated entropy of the observed data from the theoretical maximum under the randomness hypothesis. This test offers a real alternative to the conventional runs test. Critical percentage points, based on simulations, are provided for testing the hypothesis of randomness. Power calculations using dependent data show that the proposed test has higher power against the runs test for short series, and it is similar to the runs test for long series. The test is applied to two published data sets that wree investigated by others with respect to their randomness.     

Capacity Updating Rules and Rational Belief Change

Choquet expected utility substitutes capacities for subjective probabilities to explain uncertainty aversion and related phenomena. This paper studies capacities as models of belief. The notions of inner and outer acceptance context are defined. These are shown to be the natural acceptance contexts when belief expansion is described by naïve Bayesian and Dempster–Shafer updating of capacities respectively. We also show that Eichberger and Kelsey's (1999b) use of Dempster–Shafer updating as a model of belief revision may lead to violations of the AGM axioms for rational belief change.     

From vice to virtue: changing portrayals of minorities in China's official media

This study considers the official media's portrayal of minority groups in the People's Republic of China. Based on a content analysis of minority-centered articles appearing in the People's Daily newspaper between the years 1950 and 2001, it is found that minorities are most frequently depicted as representatives of primitive cultures. How the government presents this image of primitive minorities, however, has been subject to significant refinement over the years. The government has stepped away from its earlier practice of characterizing ‘primitive’ minority cultures as pathologies detrimental to the political and economic development of the state in favor of a more recent emphasis on the virtues associated with minority lives. The authors suggest that this transformation in government rhetoric is attributable to changes in both Chinese politics and society.     

The Economic and Social Impacts of the CDEP Scheme in Remote Australia

The Community Development Employment Projects (CDEP) scheme is an unusual labour market and social development program for Indigenous people. Currently the CDEP scheme employs around 36,000 Indigenous Australians and accounts for over one‐quarter of total Indigenous employment. Despite the significance of the CDEP scheme, in recent times, relatively little attention has been given to the potential for the scheme to be used as an instrument for economic and social development in remote areas of Australia. This article present new evidence on the impact of the CDEP scheme on economic and social outcomes for Indigenous people in remote areas of Australia. It is concluded that the scheme has been successful in generating positive economic and community development outcomes at minimal cost to the Australian taxpayer.     

Modelling three-dimensional trajectories by using Bézier curves with application to hand motion

Summary.  A modelling approach for three-dimensional trajectories with particular application to hand reaching motions is described. Bézier curves are defined by control points which have a convenient geometrical interpretation. A fitting method for the control points to trajectory data is described. These fitted control points are then linked to covariates of interest by using a regression model. This allows the prediction of new trajectories and the ability to model the variability in trajectories. The methodology is illustrated with an application to hand trajectory modelling for ergonomics. Motion capture was used to collect a total of about 2000 hand trajectories performed by 20 subjects to a variety of targets. A simple model with strong predictive performance and interpretablility is developed. The use of hand trajectory models in the digital human models for virtual manufacturing applications is discussed.     

Developing Family Therapy Skills on a Shoe String Budget: A Peer Supervision and Training Approach

Family therapy skills are an essential tool when working with young children and their families, yet accessing family therapy training and supervision in workplace settings has become more difficult. Skills enhancement may be obtained through formal training in accredited courses, a costly undertaking, in which clinicians most often carry the entire cost for the training. In this paper, we propose that specific family therapy skills relevant to working with families of young children can be developed within a peer group format. The peer training described in this paper is extremely cost effective, easy to set up, specifically tailored to our unique training needs and the characteristics of the population of families we are working with. Further, the training allows us to develop fresh and creative ways of skills acquisition, our own ‘curriculum’, with flexible use of training techniques, depending on our particular needs at a given time. We conclude with some of the disadvantages of the model and propose ideas for future development.     

GIS technology and survey sampling methods: The Khayelitsha/Mitchell's plain 2000 survey

This paper explores the entwining of city and song with a focus on the genre of isicathamiya in the city of Pietermaritzburg. It argues that the making of song involves the shaping of new subjectivities and it looks in particular at the role of isicathamiya performance in the making and re‐making of a particular urban space. It argues that the life and history of a city or town holds within it the songs and singers that shape it culturally and thus write themselves into the memory and being of the place. The paper searches for a new cultural topography of place that embraces this view. It situates a study of two isicathamiya groups, the Washing Boys and Naughty Boys, within a study of the life of the changing and suffering city and argues that the resilience of the genre and of its singers gives it a unique place as an interpretive voice in the New Era of post‐1994 and in the Pietermaritzburg of the present.
