The census and women's work in Rangoon, 1872–1931

The colonial census was a bureaucratic device which provided an essential abstraction from social reality, a ‘statistical fix’ designed to map individual social groups in space. This paper considers the contradictions associated with colonial knowledge systems as reflected in the census grafted onto Burmese society in the nineteenth and early twentieth centuries. It attempts to chart the general adoption and adaptation, in the Burmese context, of a classificatory scheme which categorised labour as either productive or unproductive. Colonialism introduced new attitudes towards work and labour which reinforced patriarchal values which contrasted with more egalitarian Burmese socio-economic systems. The paper suggests that a simple classification of women workers as either productive or unproductive in the Burmese census between 1872 and 1931 resulted in the devaluation of their status as workers. This devaluation was a function of both real economic transformation taking place in the empire and changes in census classification, reflecting a gendering of occupations that undermined the cultural norms of Burmese society. The material result was that women became statistically less visible as economically productive workers. Such ascriptions of value to women workers were largely informed by moral considerations originating in England.

Place and Special Places: Innovations in Conservation Practice in Northern Ireland

The sense of place that relates human beings to their environment is under threat from the rising tide of placelessness which can result from potentially positive forces such as urban regeneration as well as negative ones such as incremental degradation. The concept of sense of place, and the need to protect and enhance special places, has underpinned UK conservation legislation and policy in the post-war era. In Northern Ireland, due to its distinctive settlement tradition, its troubled political circumstances and its centralised administrative system, a unique hierarchy of special places has evolved, involving areas of townscape and village character as well as conventional conservation areas. For the first time a comprehensive comparative survey of the townscape quality of most of these areas has been carried out in order to test the hypothesis that too many conservation area designations may devalue the conservation coinage. It also assesses the contribution that areas of townscape character can make in this situation, as potential conservation areas or as second-level local amenity designations. Its findings support the initial hypothesis: assessment of townscape quality on the basis of consistent criteria demonstrates a decline in the quality of more recent conservation area designations, and hence some devaluation of the coinage. However, the need for local discretion in the protection of local amenity supports the concept of areas of townscape and village character as an additional and distinct designation. This contradicts recent policy recommendations from the Northern Ireland Planning Commission and contains valuable lessons for conservation policy and practice in other parts of the UK.

CCD photometry of distant comets. III - Ensemble properties of Jupiter-family comets

We describe the results of a ground-based observational "snapshot" study of Jupiter-family comets in the heliocentric range 2.29 AU less than or equal to R-h less than or equal to 5.72 AU. Results are presented based on observations from the 1m JKT on the island of La Palma. A total of 25 comets were targeted with 15 being positively detected. Broad-band VRI photometry was performed to determine dimensions, colour indices, and dust production rates in terms of the "A frho" formalism. The results for selected comets are compared with previous investigations. Ensemble properties of the Jupiter- family population have been investigated by combining the results presented here with those of Lowry et al. (1999), and Lowry & Fitzsimmons (2001). We find that the cumulative size distribution of the Jupiter-family comets can be described by a power law of the form; Sigma(> r) proportional to r(-1.6+/- 0.1). This size distribution is considerably shallower than that found for the observed Edgeworth-Kuiper belt objects, which may reflect either an intrinsic difference at small km- sizes in the belt, or the various processes affecting the nuclei of comets as their orbits evolve from the Edgeworth- Kuiper belt to the inner Solar system. Also, there would appear to be no correlation between nuclear absolute magnitude and perihelion distance. Finally, for the sample of active comets, there is a distinct correlation between absolute R band magnitude and perihelion distance, which can be explained by either a discovery bias towards brighter comets or in terms of "rubble" mantle formation.

Electron impact excitation of C IV

Energy levels and radiative rates for transitions among the lowest 24 fine-structure levels belonging to the ls(2) nl (n <5) configurations of Li-like C IV have been calculated using the fully relativistic GRASP code. Additionally, collision strengths for transitions among these levels have been computed over a wide energy range below 28 Ry, using the Dirac Atomic R- matrix Code. Resonances have been resolved in a fine energy mesh in order to calculate the effective collision strengths. Results for radiative rates, collision strengths, and effective collision strengths are presented for all transitions. Comparisons with other available results are made, and the accuracy of the present data is assessed. Energy levels are expected to be accurate to within 1%, while other parameters are probably accurate to better than 20%.
