A population sample registry for public health survey investigations: methods,lessons, and successes
Katherine A. James Arnold H. Levinson Yaqiang Li Carsten Baumann Ali Maffey 《International Journal of Social Research Methodology》2018,21(5):565-574
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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation. 相似文献
