A population sample registry for public health survey investigations: methods,lessons, and successes

Public health relies on sample surveys to monitor the health of populations and investigate factors that contribute to population health and illness. Such investigations require surveying individuals who are selected in ways that support statistical inference to the population. Faced with rising costs and declining participation, survey researchers are exploring economical ways to recruit samples that validly represent larger populations. The current report describes an innovative resource, the Colorado Adult Population Sample–Survey Research Registry, which maintains survey access to respondents from a probability-based state health survey. We describe recruitment and retention strategies, explore representativeness, report several studies that used the registry, and discuss future directions.     

« Comment ? Vous n’avez pas de projet ? » : ethnographie du démarchage en matière de crédit à la consommation

Many a product and service is proposed to consumers who have not individually expressed any prior interest to a salesperson or a firm. Two situations of prospecting people for a revolving credit are presented. Based on data gathered during a month of observation in the company of salespersons who deal in this type of credit, the processes are analyzed that these persons use to arouse a potential buyer's interest. Light is shed on the organizational, material and technical conditions that enable them to turn the latter into a customer or, at least, to make interactions with him/her last longer. This analysis of one form of mediation in the marketing of credit also sheds light on the situations of those who subscribe to loans, whether or not they are over indebted.     

The effect of accounting standards on Big Bath behavior

This paper investigates the influence of accounting standards on systematic earnings understatement. To isolate the effect of reporting regulations from those of other institutional drivers of earnings management, Holthausen (2003) proposes analyzing reporting practices in a country undergoing a transition in accounting standards. We respond to this call by analyzing earnings management practices of large German-listed companies before and after their transitions from German GAAP to IFRS. Specifically, we focus on Big Bath behavior following Chief Financial Officer turnovers between 1999 and 2006. Our findings provide evidence of the effect of accounting standards on the existence of this particular earnings understatement pattern. However, while we detect Big Bath behavior for our sample of German GAAP firms, we find no such indication for those firms reporting under IFRS. Controlling for alternative explanations such as self-selection bias does not change our findings. We conclude that accounting standards seem to have a considerable influence on earnings management behavior, independent of managers’ and auditors’ incentives.     

5‐Month‐Olds’ Categorization of Novel Objects: Task and Measure Dependence

To examine key parameters of the initial conditions in early category learning, two studies compared 5‐month‐olds’ object categorization between tasks involving previously unseen novel objects, and between measures within tasks. Infants in Experiment 1 participated in a visual familiarization–novelty preference (VFNP) task with two‐dimensional (2D) stimulus images. Infants provided no evidence of categorization by either their looking or their examining even though infants in previous research systematically categorized the same objects by examining when they could handle them directly. Infants in Experiment 2 participated in a VFNP task with 3D stimulus objects that allowed visual examination of objects’ 3D instantiation while denying manual contact with the objects. Under these conditions, infants demonstrated categorization by examining but not by looking. Focused examination appears to be a key component of young infants’ ability to form category representations of novel objects, and 3D instantiation appears to better engage such examining.     

Constructing poverty in anti-welfare Singapore

In recent years, attention on the issue of poverty in Singapore has been increasingly placed in the spotlight. This study examines the various types of attitudes among Singaporeans and how they are formed, relating them to the broader institutional context of Singapore. A mixed method design is employed where clusters or groups of attitudes are derived through the use of cluster analysis. Subsequently, discourses of poverty and welfare attitudes are construed through qualitative interviews with the aid of Foucauldian Discourse Analysis. Quantitative findings point to three clusters of attitudes: ‘Conservatives’, ‘Liberals’, and ‘Sui Generis’. Qualitative findings, however, show that ‘Sui Generis’ ultimately align themselves closer to either ‘Conservatives’ or ‘Liberals’ in their discourses of welfare. In fact, respondents in all three clusters reproduce state discourses, albeit in varying ways. In essence, this study explicates poverty and welfare attitudes as a product of social identities premised on subjective notions that are shaped by state discourses of meritocracy, self-reliance and anti-welfarism. It is thus argued that current socio-political constructions of poverty ensue a paucity of major welfare reform in the near future of Singapore.     

Permutation tests of scale using deviances

Robust tests for comparing scale parameters, based on deviances—absolute deviations from the median—are examined. Higgins (2004) proposed a permutation test for comparing two treatments based on the ratio of deviances, but the performance of this procedure has not been investigated. A simulation study examines the performance of Higgins’ test relative to other tests of scale utilizing deviances that have been shown in the literature to have good properties. An extension of Higgins’ procedure to three or more treatments is proposed, and a second simulation study compares its performance to other omnibus tests for comparing scale. While no procedure emerged as a preferred choice in every scenario, Higgins’ tests are found to perform well overall with respect to Type I error rate and power.     

Religion in the Lives of Older Women Serving Life in Prison

This exploratory qualitative study examined the roles of religiousness in the lives of 21 older women (mean age = 63) serving life sentences in one southern state. Based on survey and focus group methodology, several themes emerged as important focal points, including early religious experiences prior to incarceration, imprisonment and religious doubt, participation in formal and informal religious activities, and use of religion in coping with stressors such as interpersonal relationships, trauma, and health statuses. Irrespective of their religious upbringing, all participants agreed that religiosity/spirituality played a key role in their ability to cope with their prison experience as well as for maintaining hope and the opportunity for release.     

QUANTIFYING THE LIFE CYCLE OF SCHOLARLY ARTICLES ACROSS FIELDS OF ECONOMIC RESEARCH

Does the life cycle of economic papers differ across fields of economic research? By constructing and analyzing a large dataset that combines information on 9,672 articles published in the top five economic journals from 1970 to 2000 with detailed yearly citation data obtained from Google Scholar, we find that published articles do have a life cycle that differs across fields of economic research (which we divide into the categories of applied, applied theory, econometric methods, and theory). Applied and applied theory papers are the clear winners in terms of citation counts. For the first years after their publication, they receive higher numbers of citations per year than papers in other fields of research do. They also reach a higher peak number of citations per year and apparently sustain those peak levels for longer, in addition to being cited over longer periods of time (i.e., they have a longer lifespan). Citation patterns are much less favorable for theoretical papers, which are the object of fewer citations per annum in the first years following publication, have lower peak numbers and a shorter lifespan. Econometric method papers are a special case; the pattern for most of these papers is similar to the pattern for theory papers, but the most successful papers (as measured by the number of citations) on econometric methods are also the most successful papers in the entire discipline of economics.

Multinomial Selection in the Presence of Infinite Alternatives

We propose a new procedure for the multinomial selection problem to solve a real problem of any modern Air Force: the elaboration of better air-to-air tactics for Beyond Visual Range air-to-air combat that maximize its aircraft survival probability H(θ, ω), as well as enemy aircraft downing probability G(θ, ω). In this study, using a low-resolution simulator with generic parameters for the aircraft and missiles, we could increase an average success rate of 16.69% and 16.23% for H(θ, ω) and G(θ, ω), respectively, to an average success rate of 76.85% and 79.30%. We can assure with low probability of being wrong that the selected tactic has greater probability of yielding greater success rates in both H(θ, ω) and G(θ, ω) than any simulated tactic.
