How Children Spend Their Time: A Sample Survey for Use in Exposure and Risk Assessments

Children are becoming an increasingly important focus for exposure and risk assessments because they are more sensitive than adults to environmental contaminants. A necessary step in measuring the extent of children's exposure and in calculating risk assessments is to document how and where children spend their time. This 1990-1991 survey of 1000 households was designed for this purpose, targeting children between 5 and 12 years of age, in six states in varied geographic regions. The behavior of children was sampled on both weekdays and weekends over all four seasons of the year using a retrospective time diary to allocate time to activities during the previous 24 h. Information was obtained on the kinds and locations of activities, the nature of the microenvironments of the locations, and the time spent in the different environments. Measures of variability in addition to mean hours per day are reported. Results of this study closely match those of earlier research on California children's activities done by the California Air Resources Board. One important finding of the survey was that 5- to 12-year-old children in all geographic regions spend most of their time indoors at home, indicating that risk assessments should focus on indoor, on-site hazards.     

Supporting People with a Mental Handicap in the Community: A Social Psychological Perspective

Community care is a key concept in policy-making and service provision for people with a mental handicap. Yet the nature of the 'community' and the source of 'care' referred to is rarely specified. The meaning of 'community' is examined in relation to sociological and social psychological research and the assumption that geographical proximity promotes shared identity and caring relationships is called into question. It is argued that an emphasis on place and nostalgic notions of neighbourliness can obscure the difficult social psychological work of creating relationships within which people with a mental handicap can develop positive social and personal identities. The paper emphasises the importance of such relationships and argues that, for many people with a mental handicap, spontaneous local contact will not provide adequate levels of support and involvement. The creation of artificially maintained supportive networks is recommended and the resource implications of achieving good-quality care in the community are noted.     

Spatial Planning in Ghana: Exploring the Contradictions

The purpose of this research is twofold: to explore the complexity of spatial plan preparation and implementation in Ghana using Kumasi as a case study; and second, to examine the contradictions of spatial plans and ‘actual development’ occurring in Kumasi. Using social science research methods (semi-structured interviews) and physical survey (land use plans), findings indicate that spatial planning in Kumasi is a bureaucratic process hijacked by urban planning agencies with limited involvement of urban residents. As a result, urban development is considerably influenced by spontaneous informal development patterns (i.e. self-organization). This phenomenon of self-organization is expressed in a context of uncertainty created by weak spatial planning system which encourages haphazard development. Regrettably, in Kumasi, self-organization is often overlooked by spatial planning agencies as they focused on rigid and exclusionary spatial plans. This paper advocates consideration and integration of self-organization processes in spatial planning efforts to respond adequately to the urban development challenges confronting Kumasi.     

Intervention Research as Management Research in Practice: Learning from a Case in the Fashion Design Industry

Research in the field of management and organizational sciences has yielded a deeper understanding of many emerging business issues. However, the relevance of the contributions has been increasingly criticized, in both the academic and public spheres. We propose the intervention research approach – originally developed by the research group at Ecole des Mines de Paris – as a design science approach able to address both the relevance gap issue and the growing complexity of management practice. It is argued that increasing our understanding of management requires research that is more insightful, influential and immediately applicable. This in turn requires closer collaboration between management and researchers during the inquiry process, which is not always easy to achieve. An illustrative case study of an intervention research project focusing on creativity, conducted in Italy in collaboration with a fashion company, demonstrates how intervention research can be rigorous and relevant to practitioners, and how it can advance theoretical knowledge in management science.     

STIRring the grid: engaging energy systems design and planning in the context of urban sociotechnical imaginaries

Since the first electrification systems were established in the United States between 1910 and 1930, energy systems governance at the municipal level has included competing visions for how engineering design and energy policy-making should foster particular social outcomes. Using Phoenix as a representative metropolitan area, and the cases of distributed generation and in-home power management devices as examples, this paper explores how the norms and values embedded in energy systems design and planning shape how residents experience change in the energy grid. Through these case studies, the authors argue that such “sociotechnical imaginaries” – collectively formed visions of social life related to science and technology development – are a crucial, yet overlooked, pathway for social science to engage in fostering socially reflexive mechanisms in energy development. To conclude, the authors outline a research program for applying the established methodology of socio-technical integration research (STIR) in order to develop socially reflexive capacities in municipal energy producing, regulating, and planning institutions. Such a program has the ability to produce a deeper intellectual understanding of how energy development occurs, and in doing so generate new pathways for fostering cultural and material changes in the structure of contemporary energy systems.     

A Conceptual Base for ‘Second-Generation’ Programs in Gerontological Social Work

A framework developed by Vance promises better understanding of the mechanisms by which various kinds of severely deprived environments produce high rates of cognitive, emotional, and personality disabilities. Effort is focused on assessing how Vance's concepts may aid in reconceptualizing and reorganizing much Human Behavior and Social Environment content to facilitate the integration of seemingly unrelated findings and conflicting theories on the relationship between disability, poverty, and alienation. The potential for enhancing teaching and development of interventive strategies is explored.     

Determinanten des Wiedereinstiegs von Müttern in den Arbeitsmarkt in Vollzeit oder Teilzeit

This paper deals with the question which determinants influence the re-entry of mothers on the labor market after the first childbirth. Contrary to existing studies it is possible to distinguish empirically between full time and part time employment after re-entry by employing the newly available BASiD-data. Theoretical arguments indicate that women decide deliberately for a part or full time job due to labor market restriction, their household und family situation and institutional rules which vary in time. Empirically this paper focuses on mothers in West Germany because the data includes a long observation period before reunification. Based on event history models we can show that the determinants for full and part time re-entries differ substantially. Hence it can be reasoned that full and part time jobs for re-entry after birth are not simple substitutes for the women.     

Missing observations in time series

A method based on forecasting techniques is proposed to estimate missing observations in time series. Using mean squares, this method is compared to the minimum mean square estimate.     

Tall claims? Sense and nonsense about the importance of height of US presidents

According to both the scientific literature and popular media, all one needs to win a US presidential election is to be taller than one's opponent. Yet, such claims are often based on an arbitrary selection of elections, and inadequate statistical analysis. Using data on all presidential elections, we show that height is indeed an important factor in the US presidential elections. Candidates that were taller than their opponents received more popular votes, although they were not significantly more likely to win the actual election. Taller presidents were also more likely to be reelected. In addition, presidents were, on average, much taller than men from the same birth cohort. The advantage of taller candidates is potentially explained by perceptions associated with height: taller presidents are rated by experts as ‘greater’, and having more leadership and communication skills. We conclude that height is an important characteristic in choosing and evaluating political leaders.
