The Future of Fieldwork in a Market Economy
The economic reforms of the past decade have had a dramatic impact on social services. The application of market forces to the welfare sector—including competition, contestability, contracting and diminishing funding of strictly defined policy objectives—has exerted an influence on social work education. This impact has been particularly sharply felt by those engaged in supervised field practice programmes in schools of social work. In this paper, the writers outline their experiences and undertake a process of analysis and reflection with the aim of creating a shift in thinking about fieldwork which encourages the development of new models for the achievement of fieldwork goals.
Methods used to teach social work students in the field: A research report from New Zealand
This article reports the findings of research conducted in three schools of social work in New Zealand on 'methods' used to teach social work students in the field. Students were polled before the first placement ( N = 80) to find how 'effective' they rated a range of teaching methods. This was followed up by a post-placement student survey ( N = 77) to ascertain the extent to which these same methods were employed by field educators. Pre- and post-placement student results were compared with the effectiveness ratings that field educators ( N = 130) gave to each method. Field educator and student pre-placement ratings listed most methods as being effective or very effective. Post-placement student survey results suggest consistent incongruity between the effectiveness ratings given to each 'method' by field educators, and the degree to which field educators actually utilised the methods with students during the field placement. Students report that methods enabling the direct observation of their practice were amongst those least used in the field.
The peculiar thermo-structural behavior of the anionic lipid DMPG.
Aqueous dispersions of the anionic phospholipid dimyristoyl phosphatidylglycerol (DMPG), around 100 mM ionic strength, are known to exhibit a thermal behavior similar to that of the largely studied lipid dimyristoyl phosphatidylcholine (DMPC), which undergoes a gel to liquid crystalline phase transition at 23 degrees C, well characterized by differential scanning calorimetry (DSC), and other methods. However, at low ionic strength, DMPG has been shown to present a large gel-fluid transition region, ranging from 18 to 35 degrees C. This intermediate phase is optically transparent and characterized by a continuous change in membrane packing. Structural properties of the DMPG gel-fluid transition region will be discussed, based on results obtained by several techniques: electron spin resonance (ESR) of spin labels at the membrane surface and intercalated at different depths in the bilayer; light scattering; DSC; small angle X-ray scattering (SAXS); and fluorescence spectroscopy of probes in the bilayer.
