Perceptions of children's credibility were studied in two experiments wherein participants watched a videotape of a 4- to 5- or a 6- to 7-year old child report details of a play session that had been experienced once (single-event) or was the last in a series of four similar play sessions (repeat-event). The child's report was classified as high or low accurate. In Experiments 1 and 2, reports of repeat-event children were judged to be less believable on several measures. In Experiment 1, younger children were viewed as less credible than older children. In both experiments, neither undergraduates nor community members correctly discriminated between high- and low-accurate reports. Content analysis in Study 3 revealed the relationship between age and event frequency and children's credibility ratings was mediated by the internal consistency of children's reports. Recent research on children's reports of instances of repeated events has identified several challenges facing children who report repeated abuse. These data bring to light another potential difficulty for these children.  相似文献

There are several paths of terror at seaports, terminals, inland waterways, and pipelines for entry of persons, materials, and weapons and for access to destroy seaport infrastructure, ships, equipment, and people so as to disrupt economic activity. This research seeks to:
  • 1 Examine the probability of terror events via these paths and to determine a strategy to create barriers to entry and access, and to ensure the likelihood of these events is near zero.
  • 2 Identify specific actions taken, and by whom, to accomplish the above objective, considering interacting government levels and public–private partnerships.
  • 3 Suggest apparent inaction where a probability of terror remains, albeit judged more qualitatively than quantitatively.
The need for secrecy and the reality of erroneous public information complicates the task of researcher and terrorist alike.  相似文献

Workers' compensation provides medical care and income maintenance protection to workers disabled from work-related injury or illness. This program is of considerable interest to the Social Security Administration (SSA) from several perspectives. For example, since 1965 Social Security Disability Insurance (DI) benefits and workers' compensation payments have been integrated. Information on the experience under workers' compensation provides a framework for examining questions concerning gaps and overlaps in the Nation's social insurance system. In addition, since December 1969 SSA has administered claims filed through 1973 under part B of the Black Lung program--the program providing income maintenance protection to coal miners disabled by pneumoconiosis. The workers' compensation experience reported here consists of information on benefits for work-related injury and disease, including data on the combined benefits paid under the entire Federal Black Lung program administered by the Labor Department and SSA.  相似文献

This research examines in detail the structure of the issue public for health care reform, drawing from extensive, nationally representative survey data tapping general attentiveness to news and public affairs, specific interests in health care issues, and motivations (e.g., personal health and financial conditions) to follow health care reform issues. We furthermore adopt a multi-dimensional approach to defining the contours of the issue public for health care policy, separately studying its cognitive, affective, and behavioral underpinnings. Results indicate only weak interconnections across these dimensions—measured through health care knowledge, holding strong opinions on health care issues, and participation in health-related political activities, respectively—and somewhat different structural and motivational patterns underlying each. Theoretical, conceptual and methodological implications of these findings are discussed.Vincent Price and Joseph N. Cappella are Professors in the Annenberg School for Communication at the University of Pennsylvania, where Clarissa David, Brian Goldthorpe, and Marci McCoy Roth are doctoral students. Gathering of the data reported here was supported by grants to Vincent Price and Joseph N. Cappella from The National Science Foundation (Grant EIA-0306801) and the Annenberg Public Policy Center of the University of Pennsylvania. Views expressed are those of the authors alone and do not necessarily reflect opinions of the sponsoring agencies.  相似文献
