Why sociology does not need to be saved: Analytic reflections on public sociologies

After reviewing the debate about public sociologies in the American Sociological Association over the past few years, we offer a response to calls for “saving sociology” from the Burawoy approach as well as an analytic critique of the former ASA president's “For Public Sociology” address. While being sympathetic to the basic idea of public sociologies, we argue that the “reflexive” and “critical” categories of sociology, as Burawoy has conceptualized them, are too ambiguous and value-laden to allow for empirical investigation of the different major orientations of sociological research and the ways the discipline can address non-academic audiences. Debates about the future of sociology should be undertaken with empirical evidence, and we need a theoretical approach that can allow us to compare both disciplines and nations as well as taking into account the institutional context of the universities in which we operate. Research into the conditions under which professional, critical, policy, and public sociologies could work together for the larger disciplinary and societal good is called for instead of overheated rhetoric both for and against public sociologies.     

Non-ignorable missing covariate data in survival analysis: a case-study of an International Breast Cancer Study Group trial

Summary.  Non-ignorable missing data, a serious problem in both clinical trials and observational studies, can lead to biased inferences. Quality-of-life measures have become increasingly popular in clinical trials. However, these measures are often incompletely observed, and investigators may suspect that missing quality-of-life data are likely to be non-ignorable. Although several recent references have addressed missing covariates in survival analysis, they all required the assumption that missingness is at random or that all covariates are discrete. We present a method for estimating the parameters in the Cox proportional hazards model when missing covariates may be non-ignorable and continuous or discrete. Our method is useful in reducing the bias and improving efficiency in the presence of missing data. The methodology clearly specifies assumptions about the missing data mechanism and, through sensitivity analysis, helps investigators to understand the potential effect of missing data on study results.     

Statistics for weighing benefits and harms in a proposed genetic substudy of a randomized cancer prevention trial

Summary.  When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes.     

Real nonparametric regression using complex wavelets

Summary.  Wavelet shrinkage is an effective nonparametric regression technique, especially when the underlying curve has irregular features such as spikes or discontinuities. The basic idea is simple: take the discrete wavelet transform of data consisting of a signal corrupted by noise; shrink or remove the wavelet coefficients to remove the noise; then invert the discrete wavelet transform to form an estimate of the true underlying curve. Various researchers have proposed increasingly sophisticated methods of doing this by using real-valued wavelets. Complex-valued wavelets exist but are rarely used. We propose two new complex-valued wavelet shrinkage techniques: one based on multiwavelet style shrinkage and the other using Bayesian methods. Extensive simulations show that our methods almost always give significantly more accurate estimates than methods based on real-valued wavelets. Further, our multiwavelet style shrinkage method is both simpler and dramatically faster than its competitors. To understand the excellent performance of this method we present a new risk bound on its hard thresholded coefficients.     

Buying a Dream: Alternative Models of Demand for Lotto

Existing lotto demand models utilize effective price, computed as the face value of a ticket minus the expected value of prize money per ticket, as their primary explanatory variable. By contrast, this article proposes a key role for consumption benefit or "fun" in the demand for gambling in general and lotto demand in particular. It develops an alternative model of lotto demand that focuses on the maximum possible prize. When this is tested against the traditional model using data from the U.K. National Lottery, we find that jackpot considerations exert an influence over and above that of variations in effective price.     

Awkward Customers? Parents and Provision for Special Educational Needs

This article selectively reports on a small-scale qualitative exploration of the experiences of families who had undergone recent conflict with special educational needs (SEN) professionals. The data were collected over the spring and summer terms of 2001 from 10 families in two local education authorities (LEAs) in the English midlands. The research aimed to examine the parents' perspectives on points of conflict or dissatisfaction between themselves and education professionals. It was concerned with the parents' points of view regarding their pursuit of desired outcomes for their children and the factors that helped or hindered their endeavours. The project found that the parents' negotiation of the SEN system was held by them to be exceptionally difficult and stressful compared to other troubling issues in their lives. The research suggests that dissatisfactions with SEN provision have important implications for the management of LEA Parent partnership Schemes (PPS) in ameliorating the differences between parental aspirations and governmental ambition.     

‘It's their word against mine’: young people's attitudes to the police complaints procedure in Northern Ireland

One of the central aims of the police reform process in Northern Ireland has been to increase the legitimacy of the policing structures and police officers amongst those who are served and policed by the Police Service of Northern Ireland (PSNI). To meet this aim, structures have been created to ensure that the PSNI is accountable to all sections of the community for its strategy and performance, and in monitoring the attitudes and behaviour of its officers. To that end, the Office of the Police Ombudsman for Northern Ireland (PONI), the Northern Ireland Policing Board and 26 District Policing Partnerships have been created. This paper aims to break ground by looking in some detail at young people's attitudes to and experiences of the workings of one of those new bodies, the Police Ombudsman, and to explore issues related to young people's willingness to engage with the PONI.     

Struggles with Time: the careers of parents with adult sons and daughters with learning disabilities

The experiences of parents with adult offspring with learning disability and the meanings their parental careers have for them, has been the subject of very little empirical research. In this paper we describe and examine some of the features that gave shape and meaning to the day to day lives of parents of 33 co-resident adults with learning disabilities. Their accounts of their situations revealed that 'time' was a factor of some importance. Participants suggested that socialisation into the parental role was one that continued over the life course. In addition, they also felt that the services they received were based upon an inadequate and too narrow an understanding of how they experienced 'time'. The data reveal that both 'over time' and 'in time', parents struggled to maintain a set of aspirations for a typical life. The data show that for many parents there was a slow accommodation to the constraints of service provision and, as a result, their needs for service support became less extensive.
