The Sociology of Celebrity

The sociology of celebrity (and its cousin, fame) is a relatively young field, despite having identifiable classical roots. While the topic was ignored by sociologists for many years, it has recently been taken up by both theorists and empirical researchers in sociology and a variety of related fields. In this article, I evaluate the current state of the field, and identify two major themes – celebrity as pathology and celebrity as commodity – that currently dominate the literature. In addition, I suggest additional research directions that I believe will help the field develop and mature; in particular, empirically grounded and meaning‐oriented research that reflects the lived experiences of those who swim in the sea of celebrity culture everyday. What does celebrity mean to the people who produce it, consume it, engage with it and live it? To the extent that researchers take up these questions, the sociology of celebrity will continue to be a vibrant and vigorous area of study.     

What can Statistics Contribute to a Causal Understanding?

Abstract.  We discuss the concept of causality in a broad manner. The traditional attitude in statistics has been to shy away from the causality concept. In recent years, however, a more proactive attitude to the causality concept has developed among statisticians. On the one hand, there is the school of counterfactual causality directed towards forming a better basis for clinical trials and epidemiology. On the other hand, there is the mechanistic view of causality. These developments are discussed and set into a larger context, where the often ignored role of time is emphasized. An extension of path analysis to stochastic processes is briefly presented. Causality is furthermore discussed in relation to genetic studies and to the emerging field of systems biology. Statisticians should also relate to the philosophical content of causality, especially that found in the foundations of physics.     

The construction of intellectual disability by parents and teachers

This study examines how disability is constructed by significant adults in the lives of young people with intellectual disability. Specifically, we are examined how parents of those affected by intellectual disability and teachers in special schools construct intellectual disability in talk. Using focus group interviews, we examined whether stigma might be recreated or sustained within the family and school settings of those affected by intellectual disability. Parents and school staff constructed disability as negative, articulating difference from ‘the norm’, which was claimed to drive social isolation for affected young people. There was also evidence that parents and teachers attributed less agency to young people affected by intellectual disability. Discussion orients to how parents and teachers, see themselves as advocates for those with intellectual disability highlight, whilst at the same time recreating pervasive and subtle distinctions between children with and without intellectual disability.     

State-Level 2010 Census Coverage Rates for Young Children

The Census Bureau’s demographic analysis (DA) shows that the net undercount rate for children aged 0–4 was 4.6 percent in the 2010 U.S. Decennial Census while adults (age 18 and older) had a net overcount rate of 0.7 percent. For the population aged 0–4, DA estimates are seen as more accurate than the U.S. Decennial Census because the estimates for this young population rely heavily on highly accurate birth certificate data. Given the relatively high net undercount rate for young children, it would be useful to examine census coverage rates for this population in subnational geographic units. In this study, the 2010 U.S. Decennial Census counts of children aged 0–4 are compared to the corresponding figures from the Census Bureau’s Vintage 2010 Population Estimates in each state. Differences between the 2010 U.S. Decennial Census count and the Vintage 2010 Population Estimates for the population aged 0–4 range from an estimated net undercount of 10.2 percent in Arizona to an estimated net overcount of 2.1 percent in North Dakota. Larger states tended to have higher net undercounts than smaller states. The ten largest states account for about 70 percent of the national net undercount of the population aged 0–4. Of all the factors examined here, the relative size of the Blacks Alone or in Combination plus Hispanics population is most highly correlated with the estimated net undercount of the population aged 0–4. Other measures that were highly correlated with net undercount rates for the population aged 0–4 were linguistic isolation, percent of adults without a high school degree, and the unemployment rate. In general, characteristics of people are more highly correlated with the net undercount rates of young children than the characteristics of housing units.     

Efficient crossover designs in the presence of interactions between direct and carry-over treatment effects

Crossover designs, or repeated measurements designs, are used for experiments in which t treatments are applied to each of n experimental units successively over p time periods. Such experiments are widely used in areas such as clinical trials, experimental psychology and agricultural field trials. In addition to the direct effect on the response of the treatment in the period of application, there is also the possible presence of a residual, or carry-over, effect of a treatment from one or more previous periods. We use a model in which the residual effect from a treatment depends upon the treatment applied in the succeeding period; that is, a model which includes interactions between the treatment direct and residual effects. We assume that residual effects do not persist further than one succeeding period.A particular class of strongly balanced repeated measurements designs with n=t² units and which are uniform on the periods is examined. A lower bound for the A-efficiency of the designs for estimating the direct effects is derived and it is shown that such designs are highly efficient for any number of periods p=2,…,2t.     

Random Number Generation from Right-Skewed, Symmetric, and Left-Skewed Distributions

Monte Carlo simulations have become a mainstream technique for environmental and technical risk assessments. Because their results are dependent on the quality of the involved input distributions, it is important to identify distributions that are flexible enough to model all relevant data yet efficient enough to allow thousands of evaluations necessary in a typical simulation analysis. It has been shown in recent years that the S-distribution provides accurate representations for frequency data that are symmetric or skewed to either side. This flexibility makes the S-distribution an ideal candidate for Monte Carlo analyses. To use the distribution effectively, methods must be available for drawing S-distributed random numbers. Such a method is proposed here. It is shown that S-distributed random numbers can be efficiently generated from a simple algebraic formula whose coefficients are tabulated. The method is shown step by step and illustrated with a detailed example. (The tables are accessible in electronic form in the FTP parent directory at http:@www.musc.edu/voiteo/ftp/.)     

Perceptions of charisma from thin slices of behavior predict leadership prototypicality judgments

Signaling theory suggests that people use cues transmitted by leaders to form impressions of charisma but the validity of these impressions remains unexplored. Here, we examined whether perceptions of charisma from thin slices of nonverbal behavior relate to inferences based on more information. We tested whether ratings of charisma from 5-, 15-, and 30-s clips (with no audio) of speakers delivering a message predicted evaluations of vision articulation and leadership prototypicality made from 60-s multimedia clips (with audio). The results indicated that thin-slice charisma judgments predicted the criterion scores for leadership prototypicality but not vision articulation from all of the 5-, 15-, and 30-s silent clips. The current data therefore suggest that thin slices of charisma can be valid indicators of leadership.     

Oil the Equivalence of pavlov-ushakov and kaplan-meier estimators of survival probability in multiply censored sample

It is proved that the unbiased estimator of survival probability in a multiply censored sample suggested by Pavlov & Ushakov (1980, 1984) is equivalent to the Kaplan-Meier Product-Limit estimator.     

Acquired immune deficiency syndrome projections in England and Wales: interplay of methodology and data

Since the late 1980s, regular monitoring of the human immunodeficiency virus epidemic in England and Wales has been carried out through the work of successive national working groups. One of their tasks has been to provide short-term projections of the incidence of acquired immune deficiency syndrome. In this paper the data and methods used in this projection work are reviewed and results critically assessed with the aim of highlighting the strong interaction between methodological developments and data acquisition.
