Modelling period fertility: Schooling and intervals following a birth in Eastern Africa

We describe a regression-based approach to the modelling of age-, order-, and duration-specific period fertility, using retrospective survey data. The approach produces results that are free of selection biases and can be used to study differential fertility. It is applied to Demographic and Health Survey data for Ethiopia, Kenya, Tanzania, and Zimbabwe to investigate differential trends in fertility by education. Parity progression fell and the intervals following each birth lengthened between the 1970s and 2000s in all four countries. Fertility fell most among women with secondary education. In contrast to other world regions, postponement of successive births for extended periods accounted for much of the initial drop in fertility in these African countries. However, family size limitation by women with secondary education in Ethiopia and Kenya and longer birth spacing in Zimbabwe also played significant roles. Thus, birth control is being adopted in Eastern Africa in response to diverse changes in fertility preferences.     

Quality of Life in Intentional Communities

The present study was initiated to investigate levels and predictors of wellbeing among inhabitants of intentional communities (ICs). An anonymous, Internet-based questionnaire was distributed to US and Canadian ICs. Responses were obtained from 913 members. Wellbeing was measured by the widely used satisfaction with life scale (SWLS). Hierarchical linear regression analyses were run to test the predictive validity of Social support, Identity fusion, Meaning in life, Community satisfaction and Life change, and Religious activity above and beyond demographic variables and personality traits. Mean scores on the SWLS were estimated to 5.27 and 5.47 (1–7 scale) for men and women, respectively. The full model explained 41.4% of the variance for men and 38.2% for women. Personality explained 13.4 (men) and 14.4% (women) of the variation, while demographic variables only had a minor impact. Overall, presence of Meaning in life and Social support were the most important predictors. The IC inhabitants reported wellbeing on par with the highest scores previously published. The findings support the contention that sustainability, in the form of a communal lifestyle of low ecological footprint, may be promoted without forfeiting wellbeing.     

Estimation of mortality from orphanhood in adulthood

This paper extends earlier research into methods for estimating adult mortality from information on the recent incidence of orphanhood. It presents a series of regression coefficients for estimating female and male mortality from synthetic cohort data on the subsequent orphanhood of those who had a living mother or father at exact age 20. Such information can be obtained either where questions about parental survival have been asked in two inquiries or by asking retrospectively about dates of orphanhood in a single survey. Although the method is somewhat sensitive to errors in the reporting of ages and dates, it is a promising source of up-to-date estimates of adult mortality that are free from bias due to the underreporting of the orphanhood of young children ("the adoption effect").     

The Political Attitudes of Australian Voters and Candidates

Modern theories of political representation assume that there will be little congruence between the views of political elites and the voters they govern. This paper uses survey data collected among candidates and voters at the 1987 Australian federal election to examine the extent of elite-mass differences on a range of 33 issues. The results show that Labor candidates and Labor voters are more likely to disagree on political issues, while Liberal-National candidates and voters are more likely to agree. Candidates of all parties are more liberal on issues such as Asian immigration, law enforcement and the protection of the environment, compared to their voters, while Senate candidates are more liberal than House of Representatives candidates. Finally, as other studies have found, candidates with constituency responsibilities, in this case those standing for the House of Representatives and incumbents, are more likely to be closer to the views of their party's voters than Senate and non-incumbent candidates.     

Managing the introduction of new technology

Most of the existing literature on the implications of new technology focuses on either its ‘impact’ or the social choices that lie behind strategies for its introduction into work organisations. The problems of managing the implementation of new technology have yet to be extensively examined despite this being one of the most critical aspects in the process of technological change. The findings from two case studies are presented which show how managers in the organisations concerned developed contrasting approaches to the problem of implementation in the context of opportunities and constraints presented by product markets and technological advance. Similarities between the two approaches are identified, in particular the role played by top management support in facilitating the acceptance of the new technology. The argument that management is able to develop a single unitary strategy towards the introduction of new technology is rejected in favour of a view of managerial actions as a series of flexible and changing sub-strategies associated with different stages in the process of change.
