This research studies fear patterns within fear appeal anti-speeding television commercials. A pattern of fear is the sequence of fear arousal and fear reduction, if any, that is felt by the viewing audience when exposed to a fear appeal advertisement. Many road safety advertisers use fear appeals, such as "shock" advertising, that result in fear arousal, leaving the viewer feeling extremely tense. The moment-to-moment reactions of young drivers to 12 road safety commercials are gauged using a dynamic, temporal measure of fear. The fear patterns generated from each ad are analyzed and a new perspective on creating fear appeal road safety advertisements, with an emphasis on fear-relief, fear-partial relief, and fear-only patterns, is discussed. 相似文献

In this article, a new framework for improving risk assessments of novel genetically engineered organisms (GEOs) is developed and applied. The Procedurally Robust Risk Assessment Framework (PRRAF) provides a set of principles and criteria for assessing and enhancing risk assessment protocols for GEOs under conditions of high uncertainty. The application of PRRAF is demonstrated using the case of a genetically engineered mosquito designed to kill its wild population and therefore decrease disease transmission. Assessments for regulatory approval of this genetically engineered insect fall short of several PPRAF criteria under the principles of humility, procedural validity, inclusion, anticipation, and reflexivity. With the emergence of GEOs designed to spread in ecosystems, such as those with gene drives, it will become increasingly important for regulatory agencies and technology developers to bolster their risk analysis methods and processes prior to field testing. PRRAF can be used as a flexible guide for doing so within a variety of institutional, regulatory, and governance contexts. 相似文献

Abstract: Detection of mass graves utilizing the hyperspectral information in airborne or satellite imagery is an untested application of remote sensing technology. We examined the in situ spectral reflectance of an experimental animal mass grave in a tropical moist forest environment and compared it to an identically constructed false grave which was refilled with soil, but contained no cattle carcasses over the course of a 16‐month period. The separability of the in situ reflectance spectra was examined with a combination of feature selection and five different nonparametric pattern classifiers. We also scaled up the analysis to examine the spectral signature of the same experimental mass grave from an air‐borne hyperspectral image collected 1 month following burial. Our results indicate that at both scales (in situ and airborne), the experimental grave had a spectral signature that was distinct and therefore detectable from the false grave. In addition, we observed that vegetation regeneration was severely inhibited over the mass grave containing cattle carcasses for up to a period of 16 months. This experimental study has demonstrated the real utility of airborne hyperspectral imagery for the detection of a relatively small mass grave (5 m2) within a specific climatic zone. Other climatic zones will require similar actualistic modeling studies, but it is clear that the applications of this technology provide the international community with both an early detection tool and a tool for ongoing monitoring. 相似文献

Abstract: Mitochondrial DNA analysis of skeletal material is invaluable in forensic identification, although results can vary widely among remains. Previous studies have included bones of different ages, burial conditions, and even species. In the research presented, a collection of human remains that lacked major confounders such as burial age, interment style, and gross environmental conditions, while displaying a very broad range of skeletal degradation, were examined for both mitochondrial DNA (mtDNA) quality and quantity. Overall skeletal weathering, individual bone weathering, and bone variety were considered. Neither skeletal nor bone weathering influenced DNA quality or quantity, indicating that factors that degrade bone do not have the same effect on DNA. In contrast, bone variety, regardless of weathering level, was a significant element in DNA amplification success. Taken together, the results indicate that neither skeletal nor individual bone appearance are reliable indicators of subsequent mtDNA typing outcomes, while the type of bone assayed is. 相似文献

Evidence relevant to claims of self-control theory concerning the connection between social integration and crime/deviance
is offered. Using data from a survey of the population of a southwestern city that permit measurement of two types of social
integration, including socially supportive networks, we (1) investigate the association between self-control and social integration,
and (2) attempt to ascertain if social integration is associated with misbehavior independently of self-control. Results suggest
that self-control is a persistent predictor of misconduct that operates independently of social integration. Although interpersonal
social integration appears to stand alone in its association with deviance, community integration shows no relationship with
self-control or misbehavior.

Perceived conflict patterns and relationship quality associated with verbal sexual coercion by male dating partners 总被引:1,自引:0,他引:1
The study of verbal sexual coercion in heterosexual relationships is controversial because nonphysical coercive tactics are often viewed as socially acceptable. It was hypothesized that, within couples, verbal sexual coercion will occur within a larger context of destructive conflict tactics and diminished relationship quality. Female undergraduates in consensually sexual dating relationships (N = 193) provided self-report data on male partner verbal sexual coercion perceived conflict behaviors, and relationship quality. About 21% reported current partner verbal sexual coercion. Results reveal positive associations between feeling pressured into unwanted sex and perceptions of partner psychological abuse and destructive verbal conflict patterns. Also as expected, partner verbal sexual coercion is negatively associated with relationship satisfaction and sexual functioning. The authors conclude that women's experiences of verbal sexual coercion in heterosexual relationships may reflect broader problems in the dyadic context. 相似文献

There is a paucity of research examining substance abuse issues among women prisoners. This study explored relationships between perceived stress, impulsivity, and beliefs in the efficacy of drugs as these variables pertain to self-reported drug use severity. Women prisoners (N = 100) participated in structured face-to-face interviews based on established research instruments. Although there was no significant correlation between demographic characteristics and substance use severity, positive relationships were found between substance use severity, perceived stress, impulsivity, and beliefs. A multiple linear model was estimated regressing drug use severity on beliefs, impulsivity, and perceived stress. Only the measures of beliefs and impulsivity were significant correlates of drug use severity. Implications are discussed for prison substance abuse programming and future research. 相似文献
