High foetal mortality and birth intervals

Abstract Studies of birth intervals have generally separated the process into: (1) the period of infertility following a pregnancy termination; (2) the length ofthe interval from the end of the infertile period to the next conception (which reflects the probability of conception), and (3) the average duration of pregnancy for both live births and foetal deaths.(1) Empirically derived intervals between successive live births average from 19 to 30 lunar months(2) (Table 1), depending upon the population studied and the birth order.(3) Estimates of conception rates using birth intervals data require some estimate of the extent to which foetal wastage increases the birth interval.     

A STUDY OF AUTOMOBILE INVENTORY INVESTMENT

The volatile fluctuations in automobile inventory levels are explained well by the stock-adjustment model estimated in this paper on monthly time-series data. In contrast to the findings of most previous inventory studies, fluctuations in financial inventory carrying costs (as measured by a service cost of capital) are found to influence the target auto stocks in both a statistically significant and economically important manner. Also, the speed-of-adjustment of automobile inventories to their target level is estimated to be relatively fast, about thirty percent per month.     

Social Area Analysis in Comparative Perspective: Moscow in 1897 as a Preindustrial City

Shevky-Bell social area analysis was a postwar attempt to isolate the essential dimensions delineating intraurban subareas in modern communities. The premise of the present paper is that the Shevky-Bell model has not been given adequate study through comparative research. The purpose of the study is to test the usefulness of the Shevky-Bell model in an analysis of prerevolutionary Moscow, a major city with a preindustrial urban structure. The basic finding reported in this paper is that the rotated factors that emerge in an analysis of prerevolutionary Moscow resemble the Shevky-Bell model. However, the rotated factor matrix more specifically fits a deviant case found earlier by Van Arsdol et al. of Kansas City and of Schwirian and Matre of Mayaguez, Puerto Rico, in which fertility appears more clearly as a dimension of social rank than of familism. The factors also tend to be complex, suggesting a less differentiated community system. These results suggest that an advanced stage of community development is a pre-condition of the Shevky-Bell model as it was originally formulated.     

Applying Single-Case Evaluation in Social Work

Summary This article reports on a research project involving the useof single-case designs on an agency-wide basis within KirkleesMetropolitan Education Social Work Service. Following a programmeof training, 21 social workers (69 per cent of the service)applied the methodology in 83 cases. The extent of practitionerinvolvement in this project prompted Bruce Thyer (Professorat the University of Georgia, USA and editor of Research onSocial Work Practice and author of Thyer, 1993) to state ina letter to the authors, ‘Please allow me to offer mycongratulations on a most valuable project. To my knowledge,this is the largest agency-based study of this type which hasever been conducted. Your agency social workers are especiallyto be commended for their implementation of single-case designswith real life clients and families’ (6 May 1994). Theproject's strategy was to concentrate on the prerequisites ofsingle-case methodology which include specifying target problemsand selecting an appropriate measure to monitor progress. Thetype of single-case design used was determined by the courseof natural practice, hence indicating the flexible nature andviability of this methodology in the evaluation of social workpractice. The use of single-case designs encouraged a systematicapproach in the definition of target problems, identificationof goals, selection of intervention procedures and in monitoringoutcomes. The practitioners found that single-case designs enabledcontinuous assessment of outcome data by both the clients andthe practitioners, providing a model of accountability and collaborativeworking. A paper based on this article was presented by MansoorKazi at the ADSS Research Group Conference, Stafford, 17–18November 1994.     

Informal shelter providers: Low income households sheltering the homeless

Despite the important role they play in preventing homelessness, those who shelter people who can not afford housing of their own have been neglected by researchers. This study examines the characteristics of these low income informal shelter providers. While informal shelter providers were similar to a comparison group of low income households that did not shelter others, there were also significant differences between the two groups. Informal shelter providers were more much more likely to live in single family dwellings, they were more likely to be long-term residents of the community, they were more likely to have experienced homelessness themselves, and they devoted a disproportionate share of their incomes to housing.
