Predicting body fat using weight–height indices

While body fat is the most accurate measure of obesity, its measurement requires special equipment that can be costly and time consuming to operate. Attention has thus typically focused on the easier to calculate body mass index (BMI). However, the ability of BMI to accurately identify obesity has been increasingly questioned. This paper focuses attention on whether more general body mass indices are appropriate measures of body fat. Using a data set of body fat, height, and weight measurements, general models are estimated which nest a wide variety of weight–height indices as special cases. In the absence of a race and gender categorisation, the conventional BMI was found to be the appropriate index with which to predict body fat. When such a categorisation was made, however, the BMI was never selected as the appropriate index. In general, predicted female body fat was some 10 kg higher than that of a male of identical build and predicted % body fat was over 11 percentage points higher, but age effects were smaller for females. Considerable racial differences in predicted body fat were found for males, but such differences were less marked for females. The implications of this finding for interpreting recent research on the effect of obesity on health, society, and economic factors are considered.     

Researching in the Victorian censuses: a note on a computerized,annotated bibliography of publications based substantially on the census enumerators' books

The authors describe a project, begun in 1981, to locate, list, and annotate all the published work based substantially on the census enumerators' books for nineteenth-century censuses for England and Wales. The results are currently available in a computerized file, enabling a variety of searches by topic, geographical area, and type of population. Information is provided on using the data and the computerized bibliography. The authors note that, subsequently, data for censuses of Scotland and Ireland have been added.     

Cockpits,Hangars, Boys and Galleys: Corporate Masculinities and the Development of British Airways

This article sets out to examine the role of masculinity in the development of a gendered organizational culture over time. The development of images of masculinity within one company — British Airways — is examined through content analysis of company newsletters, advertising copy, annual reports, internal memoranda, and written rules and regulations. Exploring the notion of ‘multiple masculinities’, the article traces the prominent forms of masculinity that emerged in British Airways and assesses their impact on the ways that organizational practices were developed, maintained and understood. Four key corporate images of masculinity are examined — the pilot, the steward, the engineer and the ‘native boy’— and it is argued that those images contributed to the exclusion of women and people of colour from those occupations by laying down cultural rules about the ideal typical characteristics of the job holder. The article concludes by raising questions about the value of a multiple masculinities focus in explaining changing and contradictory practices of discrimination; the primacy of extra-organizational over organizational practices; and the relationship between multiple masculinities and hegemonic masculinity. Further research is suggested into the extent to which hegemonic masculinity is undermined, over time, by changing and contradictory forms of masculinity within definite sites of gender construction.     

The role of trade unions in strategic planning

The changing climate of industrial relations has created a more puralist and complex state of relationships within the industrial sector of the economy. Trade unions and their employees are demanding and achieving a greater degree of participation in both the long and short term issues which affect company decisions in terms of either resource allocation or general policy. This article examines the role of trade unions within the context of strategic planning and argues that their increasing involvement is inevitable and their role should therefore be effectively recognized and their contribution to the development of corporate strategy ensured.     

Utilizing Bayesian predictive power in clinical trial design

The Bayesian paradigm provides an ideal platform to update uncertainties and carry them over into the future in the presence of data. Bayesian predictive power (BPP) reflects our belief in the eventual success of a clinical trial to meet its goals. In this paper we derive mathematical expressions for the most common types of outcomes, to make the BPP accessible to practitioners, facilitate fast computations in adaptive trial design simulations that use interim futility monitoring, and propose an organized BPP-based phase II-to-phase III design framework.     

Gender,Occupation, and Promotion to Management in the Nonprofit Sector

Although one can assume the work values within nonprofit organizations promote gender equality in promotion decisions, there is preliminary evidence that in the nonprofit sector women are underrepresented in higher management positions. Whereas the mechanisms resulting in underrepresentation of women in management have been studied extensively in for‐profit organizations, little is known about these mechanisms in nonprofit organizations. Is gender in nonprofit organizations—even given the underlying values of these organizations—an impediment to attaining a management position? This article presents a case study of employment patterns within the Dutch section of the humanitarian INGO Médecins Sans Frontières and focuses particularly on the effects of gender and occupation on transitions to management. The case study organization represents a “critical case” because the nature of this organization's work environment can be expected to result in a relatively high percentage of women in management. Employee records (N = 2,247) were analyzed using event history models. We found that women made the transition to management less rapidly than men, even when controlling for factors like age, previous work experience, and nationality. However, gender differences were completely explained by occupation. Those employees in female‐dominated occupations (in this case, medical personnel such as nurses) had a lower promotion‐to‐management rate than those in male‐dominated occupations (in this case, nonmedical personnel such as financial officers), irrespective of their gender. This case study highlights the importance to nonprofit management research of studying the effects of occupational sex segregation on promotion.     

Using best available science to protect critical areas in Washington state: challenges and barriers to planners

Urban development has profound impacts on ecological patterns and processes making the scientific information required for developing environmental ordinances central for mitigating these negative ecological impacts. Washington State requires that planners use the best available science (BAS) to formulate land use ordinances as part of the state’s Growth Management Act (GMA). We present empirical findings describing challenges to planners in defining “best available science” and using BAS to create local ordinances that balance development needs with natural resource protection. We interviewed city and county planners (and their consultants) in western Washington to determine what they find useful about BAS, whether or not BAS is applicable to their jurisdictions, and what constraints they experience in reviewing and using BAS to create or update their land use ordinances. Our results suggest that applying the BAS requirement is particularly difficult in urban areas. Specifically, planners had difficulty applying results from research conducted in systems dissimilar to their urban landscapes. These challenges to planners were exacerbated by (1) a lack of resources and (2) political tensions among stakeholders with competing values in urban settings. We conclude with recommendations for improving the consideration of science in statewide land-use planning.
