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

The homeless will readily list ailments they claim to have, yet they will also claim that such ailments are not a problem and do not warrant treatmente In an attempt to understand this apparent paradox, data from a sampLe of homeless individuals were re-analyzed from a social comparison perspective. It was hypothesized that increased entrenchment in homelessness (increased isolation from “nonhomeless” environments and further involvement in the homeless environment) — operationalized by longer time spent on the street and a greater number of street friends — would lead homeless individuals to alter their perceptions of what constitutes a problem worthy of treatment. Results supported this hypothesis, in direction, and in almost all tests conducted. The involvement of adaptation level theory in such a social comparison process and the implications for intelVention and treatment are discussed.  相似文献

Abstract. This paper investigates the effects of using dismissal taxes to finance unemployment benefits. We compare dismissal and employment taxes in a model with search frictions. Employment taxes give rise to externalities because firms do not take into account the effects their dismissal decisions have on others. These externalities can be tackled by using dismissal taxes to finance unemployment insurance. Taking into account the budget for unemployment insurance, employment taxes can be reduced by more than is necessary to offset the adverse effect of dismissal taxes on the value of the firm. The introduction of dismissal taxes leads to higher job creation and lower unemployment.  相似文献

Loin d'être acquise une fois pour toutes, une réputation de respectabilité doit être négociée au jour le jour au fur et à mesure que les situations et les acteurs changent. Les biens matériels jouent un rôle important dans la construction des apparences et de la respectabilité. Cette étude examine le phénomène des ‘soirées pour dames' où des femmes se rencontrent pour vendre et pour acheter de la lingerie et des accessoires sexuels. Ces rencontres à caractere commercial font ressortir la nature interactive et signifiante des échanges économiques et permettent de mieux comprendre comment se négocie la respectabilité. L'auteure examine les stratégies employées par les clientes pour maintenir les apparences de respectabilité et les techniques employées par les vendeuses pour contourner les aspects problématiques de la rencontre ainsi que la manière dont les clientes ‘approuvent’ ou ‘désapprouvent’ et l'impact de ces comportements sur la sauvegarde des apparences. Being defined as a respectable person is an ongoing concern in daily life. Respectability is continually under negotiation as situations and actors change. Commodities play an important role in the construction of appearances and of respectability. This study explores ‘Naughty Lady Parties, where lingerie and sex paraphernalia are sold. These sales encounters highlight the interactive and definitional nature of economic exchanges and offer insights into the negotiation of respectability. The strategies customers use to maintain respectable appearances and the techniques sellers use to manage problematic aspects of the encounter are explored. The roles customers play in the encounter as ‘reinforcers' and ‘naysayers' and their impact on the maintenance of respectable appearances are discussed.  相似文献

What is pilgrimage and how should we understand its social significance? Traditional analyses of religiously motivated travel have focused on praxis and ritual. Contemporary analyses have further analyzed pilgrimage as a site where religion, politics, economy, and cultural production converge. This article argues that such convergence is best understood as the product of overlapping and interacting social fields and that particular pilgrimages—as sites of contestation and negotiation—take shape in the interstitial spaces between fields. Using the case of African American Christian pilgrimage to Israel and Palestine as the “Holy Land,” this article examines the relationship between overlapping fields and the negotiation of competing interests on pilgrimage. It suggests cultural framing work as a mechanism by which actors manage tensions between these fields and their interests.  相似文献

Regulatory problems in infancy and toddlerhood have previously been associated with an increased risk of developing attention problems in childhood. We hypothesized that early regulatory problems are associated with attention problems via reduced inhibitory control. This prospective study assessed 1,459 children from birth to 8 years. Crying, feeding, and sleeping problems were assessed at 5 and 20 months via parent interviews and neurological examinations. At 20 months, inhibitory control was tested with a behavioral (snack delay) task. Attention regulation was assessed at 6 and 8 years using multiple instruments and informants. Detrimental effects of crying, feeding, and sleeping problems on attention regulation were partly mediated by children's ability to inhibit unwanted behaviors (β = ?0.04, = 0.013). Accounting for cognition diminished this indirect effect (β = ?0.01, = 0.209). Instead, the effects of crying, feeding, and sleeping problems on attention regulation were fully mediated by children's cognitive functioning (β = ?0.10, < 0.001). These results support that inhibitory control abilities partly mediate effects of crying, feeding, and sleeping problems. However, these effects may be accounted for by children's general cognitive abilities. Early regulatory problems may set infants on a course of under control of behavior into school age, and such trajectories are highly associated with general cognitive development.  相似文献

A growing knowledge regarding the influence of exercise on adverse physiologic outcomes associated with cancer and its treatment exists. Aside from its effects on psychological behavior, quality of life, and cancer-related fatigue, physical exercise can target physical and cardio-respiratory fitness, insulin regulation and metabolic syndrome, body weight and composition, and immune function in tumor patients. The increasing number of study results for different cancer types, which prove the positive influences of physical activity in cancer patients, changed the contradictory opinions which existed until the end of the last century. Although an increasing number of studies showing the positive effects of physical activity and more specifically of endurance and resistance training in cancer patients have been published, the underlying mechanisms are mostly unknown. Thus, we summarized the current knowledge of the effects of physical activity and specific training in different tumor entities with specific respect to the possible underlying mechanisms. Especially, the association between physical activity and (1) the improvement of fatigue and the role of free radicals in this process, (2) the counterbalance of tumor-induced cachexia, (3) the improvement of the immune system for supportive tumor treatment, and (4) the possible role of epigenetic modulation against tumor and tumor treatment-dependent adverse physiologic outcomes is focused.  相似文献

Negative psychological and physical effects of prostate cancer and its medical treatment may persist many years after diagnosis. The influence of a long cycling tour on rehabilitative or health-related effects with prostate cancer patients has not yet been studied. In practice, physicians and therapists rarely recommend cycling to prostate cancer. In May 2010, eight prostate cancer patients rode their bikes for over 1,408 km from Cologne to Marseille within 5 weeks. Endurance test, blood examinations (prostate-specific antigen (PSA), total testosterone, interleukin-6, oxidative stress, and antioxidant capacity) and quality of life questionnaires were completed before and after the tour. All eight subjects reached Marseille. Significant improvements could be observed in physical performance and certain quality of life scores (p?=?0.008), as well as a reduction of total testosterone (p?=?0.19). PSA levels did not change. This pilot study suggests that long bicycle tours with prostate cancer patients are feasible. Due to the missing control group and the small sample size, the results of this pilot study are limited.  相似文献

This note establishes that escalating penalty regimes with the option to self-report crimes may allow present-biased offenders to obligate themselves to refrain from committing future crimes. Self-reporting of a committed crime increases the expected costs of future criminal opportunities, possibly allowing offenders to deter their future selves from seeking immediate gratification.  相似文献
