Estimation of an indicator of the representativeness of survey response

Nonresponse is a major source of estimation error in sample surveys. The response rate is widely used to measure survey quality associated with nonresponse, but is inadequate as an indicator because of its limited relation with nonresponse bias. Schouten et al. (2009) proposed an alternative indicator, which they refer to as an indicator of representativeness or R-indicator. This indicator measures the variability of the probabilities of response for units in the population. This paper develops methods for the estimation of this R-indicator assuming that values of a set of auxiliary variables are observed for both respondents and nonrespondents. We propose bias adjustments to the point estimator proposed by Schouten et al. (2009) and demonstrate the effectiveness of this adjustment in a simulation study where it is shown that the method is valid, especially for smaller sample sizes. We also propose linearization variance estimators which avoid the need for computer-intensive replication methods and show good coverage in the simulation study even when models are not fully specified. The use of the proposed procedures is also illustrated in an application to two business surveys at Statistics Netherlands.     

Exposing College Students to Exercise: The Training Interventions and Genetics of Exercise Response (TIGER) Study

Abstract

Objective: The Training Interventions and Genetics of Exercise Response (TIGER) study is an exercise program designed to introduce sedentary college students to regular physical activity and to identify genetic factors that influence response to exercise. Participants: A multiracial/ethnic cohort (N = 1,567; 39% male), age 18 to 35 years, participated in the study. Methods: Subjects underwent 30 weeks of exercise training, 3 days/week, for 40 minutes at 65% to 85% of age- and gender-predicted maximum heart rate reserve. Multiple measures of body size/composition, heart rate, and blood pressure were obtained. Results: A total of 1,567 participants, (39% male), age 18 to 35 years, participated in the TIGER study. The prevalence of overweight/obesity in participants was 48.0%/19.3% in non-Hispanic Whites, 55.3%/24.2% in Hispanic Whites, 54.9%/25.4% in African Americans, and 38.3%/11.3% in Asians. Average within-semester retention was 68%, but overall retention (30 weeks, 2 semesters) was 20%. Conclusions: The TIGER study represents an efficacious strategy for introducing college-aged individuals to regular aerobic exercise.     

Healthy Living in Two Worlds: Testing a Wellness Curriculum for Urban Native Youth

The Healthy Living in Two Worlds project developed a wellness curriculum for urban, Northeastern Native American youth. The curriculum sought to increase physical activity, decrease or prevent recreational tobacco use, and increase healthy eating practices. The program was delivered in a summer day camp format to 16 Native American youth ages 9–13. These youth have considerable exposure to recreational tobacco use in their households and among their peers but they express an intention to resist pressure to use recreational tobacco products. Some of these youth do not eat regular meals, particularly breakfast and lunch. Program participants appear to be physically active and their activity seems to have increased after the program.     

For love and money: Navigating values at the antiques roadshow event

Antiques Roadshow Events are held in historic locations across the United Kingdom. On site, experts evaluate objects brought in by attendees, who are often cast as passive recipients, while edited highlights make up the long-running BBC TV program. Through Collaborative Event Ethnography at one Roadshow Event we show how object stories are navigated through “value talk” between attendees and experts in front of live audiences. Value is not a measurement but a dimension of the thing and its context. Stories and money are both integral in understanding worth, and final valuations are only partially shaped by given expertise.     

Residential Relocation in Later Life: A Comparison of Proactive and Reactive Moves

Proactive coping involves anticipating future events or stressors and preparing for them in advance. Housing is an important consideration in preparing for later life. This study examines residential relocation among older adults, comparing those who moved proactively with those who moved reactively. Data from the Longitudinal Study of Aging included a final sample of individuals who had relocated at Wave 2 (n = 736) and Wave 3 (n = 713). The proactive group of movers was younger, more educated, and had higher incomes. Results provide support for proactive coping theory and its application to residential relocation in later life.     

Partial publicity and gendered remembering: figuring women in culture and performance

This essay brings representational issues of female publicity into recent discussions about space, community and memory. Cultural analysts in a variety of fields have used these concepts to foreground the radically contextual and socially embedded nature of artistic production as well as to incorporate psychic and material notions of representation into the analysis of the political. I argue that such conceptual work is implicitly gendered, something made clearer by asking feminist questions about the function of memorial space in imagining publicity. To focus an interrogation, I investigate one disciplinary strain within cultural studies: theatre and performance studies. Throughout, I position performance – both theatrical and social – as an exemplary site with which to investigate the linguistic, spatial, and embodied practices of culture. Such forms expose the gendered operations of language, space and gesture as well. Furthermore, the field of performance studies has produced theoretical paradigms that derive from larger theories of memory and space. By thus positioning it as both a site of culture and a site of cultural theory, I argue that performance can illuminate the tacit gendering of culture more generally. My investigation of publicity and civic memorial will build upon three relatively recent examples of civic performance in Chicago: the performance of First Lady at the 1996 Democratic convention, the 1996 inauguration of the Jane Addams Memorial Park in Chicago, and the premiere of Chicago-born playwright David Mamet’s The Old Neighborhood in 1997. I frame both Chicago theatre and other kinds of Chicago performances as different types of civic memorial in order to speculate on relationships amongst different types of genres. More importantly, I illustrate the different ways that women function allegorically and indirectly as vehicles for imagining publicity and for lamenting its failures. My examples suggest how women – living and/or memorialized, ethnically marked and unmarked – can figure paradoxically as the object blamed for the loss of extended affiliation even as (conversely) they are also blamed for its ‘unnatural’ public promotion.     

The making of ‘real men’

This article considers the legacy of Enlightenment and Empire in settler society as a conflict of cultural values,at once a problem of justice and identity. Aotearoa/New Zealand is an exemplary case: the failure of the court system to fully acknowledge that settlement was founded on negotiation with indigenous people threatens to return this society, in constitutional and social terms, to a state of nature. I consider the problem raised by the claims to justice of indigenous Maori through the viewpoint of a major historian, and white New Zealander or Pakeha, J. G. A. Pocock. The progressivism of enlightenment history still evident in his thinking undergirds a view of Maori history as a primitive dreamtime. This misconception belies the refusal of Pakeha to acknowledge the extent to which their own view of history is a product of enlightenment myth-making. The negative British view of Maori in the nineteenth century shows the continuity of racial stereotypes since Captain Cook's encounter. Today, the judicial failure to countenance different cultural values reorients questions of justice. The state of nature returns as the absence of a constitutional framework for negotiating specifically cultural differences. The abstract universalism of liberal justice – Pakeha think justice cannot be culturally inflected – is part of the problem, and fuels Maori grievances. Yet Pakeha are increasingly turning to Maori insignia to establish a sense of national identity. Historical justice and questions of national identity remain inseparable in settler societies. The failure to consider settlement in terms of competing cultural values, evident in the problem of history, creates the conditions for an uncivil society. In this context I question the grounds for regarding acts of indigenous violence as unjustified.
