Appetitive motivation predicts the majority of personality and an ability measure: a comparison of BAS measures and a re-evaluation of the importance of RST

Our first study develops a measure of appetitive motivation and our second study compares several measures of Gray's (1987) behaviour activation system (BAS) in the prediction of the surface scales of personality. In particular, we were interested in determining the utility of the new appetitive motivation scale and Dickman's functional impulsivity scale. In comparison to other well-known measures, both scales were generally good predictors. We conclude that the appetitive motivation scale is a promising measure of BAS based upon construct validation. Contrary to previous studies which have suggested that BAS is a generally poor predictor of the surface scales of personality, we discovered appetitive motivation to be an important predictor of personality in general. Interestingly, the scale was also predictive of scores on the Baddeley reasoning test. (C) 2003 Elsevier Ltd. All rights reserved.

The practice of participatory planning at Mapoon Aboriginal settlement: Towards community control, ownership and autonomy

The practice of participatory planning in discrete Indigenous settlements has been established since the early 1990s. In addition to technical and economic goals, participatory planning also seeks community development outcomes, including community control, ownership and autonomy. This paper presents an evaluation of one such planning project, conducted at Mapoon in 1995. The Plan successfully improved physical infrastructure and housing, but had mixed success in terms of community development. Despite various efforts to follow participatory processes, the Plan was essentially a passing event, community control progressively diminished after its completion, and outcomes fell short of notions of ownership and autonomy. This suggests some misunderstandings between the practice of participatory planning and the workings of governance.

Recent developments in population projection methodology: A review

In this paper we survey five streams of research that have made important contributions to population projection methodology over the last decade. These are: (i) the evaluation of population forecasts; (ii) probabilistic methods; (iii) experiments in the projection of migration; (iv) projecting dimensions additional to age, sex and region; and (v) the use of scenarios for 'what if?' analyses and understanding population dynamics. Key developments in these areas are discussed, and a number of opportunities for further research are identified. Copyright (c) 2005 John Wiley & Sons, Ltd.

Numerical evaluation of the fields induced by body motion in or near high-field MRI scanners

In modern magnetic resonance imaging, both patients and health care workers are exposed to strong. non-uniform static magnetic fields inside and outside of the scanner. In which body movement may be able to induce electric currents in tissues which could be potentially harmful. This paper presents theoretical investigations into the spatial distribution of induced E-fields in a tissue-equivalent human model when moving at various positions around the magnet. The numerical calculations are based on an efficient. quasi-static, finite-difference scheme. Three-dimensional field profiles from an actively shielded 4 T magnet system are used and the body model projected through the field profile with normalized velocity. The simulation shows that it is possible to induce E-fields/currents near the level of physiological significance under some circumstances and provides insight into the spatial characteristics of the induced fields. The methodology presented herein can be extrapolated to very high field strengths for the evaluation of the effects of motion at a variety of field strengths and velocities. (C) 2004 Elsevier Ltd.

A process for the systematic review of community-based rehabilitation evaluation reports: formulating evidence for policy and practice

A methodological framework for conducting a systematic, mostly qualitative, meta-synthesis of community-based rehabilitation (CBR) project evaluation reports is described. Developed in the course of an international pilot study, the framework proposes a systematic review process in phases which are strongly collaborative, methodologically rigorous and detailed. Through this suggested process, valuable descriptive data about CBR practice, strategies and outcomes may be synthesized. It is anticipated that future application of this methodology will contribute to an improved evidence base for CBR, which will facilitate the development of more appropriate policy and practice guidelines for disability service delivery in developing countries. The methodology will also have potential applications in areas beyond CBR, which are similarly. evidence poor' (lacking empirical research) but 'data rich' (with plentiful descriptive and evaluative reports).
