Civic Engagement in the Era of Big Stories

Most scholars agree that news coverage of politics is the product of complicated interaction between journalists and politicians. Yet, we know little about how the interaction affects the coverage. Our analysis examines U.S. senators' press events and subsequent national network coverage from 1980–1996. Our evidence suggests that all senators can increase journalists' interest in their press events by carefully choosing the type of event and which politicians attend. In turn, such interest often translates into actual news stories, although that coverage is not guaranteed. Thus, senators can structure press events in order to increase the likelihood of coverage, but reporters understandably resist their attempts to do so. As a result, the most newsworthy press events require senators to give up control over content, creating more potential for revealing unexpected information.     

Identification through X-ray fluorescence analysis of dental restorative resin materials: a comprehensive study of noncremated, cremated, and processed-cremated individuals

Tooth-colored restorative materials are increasingly being placed in the practice of modern dentistry, replacing traditional materials such as amalgam. Many restorative resins have distinct elemental compositions that allow identification of brand. Not only are resins classifiable by elemental content, but they also survive extreme conditions such as cremation. This is of significance to the forensic odontologist because resin uniqueness adds another level of certainty in victim identification, especially when traditional means are exhausted. In this three-part study, unique combinations of resins were placed in six human cadavers (total 70 restorations). Simulated ante-mortem dental records were created. In a blind experiment, a portable X-ray fluorescence (XRF) unit was used to locate and identify the resin brands placed in the dentition. The technique was successful in location and brand identification of 53 of the restorations, which was sufficient to enable positive victim identification among the study group. This part of the experiment demonstrated the utility of portable XRF in detection and analysis of restorative materials for victim identification in field or morgue settings. Identification of individuals after cremation is a more difficult task, as the dentition is altered by shrinkage and fragmentation, and may not be comparable with a dental chart. Identification of processed cremains is a much greater challenge, as comminution obliterates all structural relationships. Under both circumstances, it is the nonbiological artifacts that aid in identification. Restorative resin fillings can survive these conditions, and can still be named by brand utilizing elemental analysis. In a continuation of the study, the cadavers were cremated in a cremation retort under standard mortuary conditions. XRF was again used to analyze retrieved resins and to identify the individuals based on restorative materials known to exist from dental records. The cremains were then processed and the analysis was repeated to determine whether restorative resins could be found under this extreme condition. Under both circumstances, sufficient surviving resin material was found to distinguish positively each individual in the study group. This study showed the utility of XRF as an analytical tool for forensic odontology and also the significance of the role of restorative resins in victim identification, even after cremation.     

Inquiry into the Scientific Basis for Bitemark Profiling and Arbitrary Distortion Compensation

Abstract: Prediction of dental characteristics from a bitemark (bitemark profiling) and arbitrary photographic distortion compensation are two practices proposed in bitemark analysis. Recent research on the effect of inherent skin tension properties in bitemark analysis suggests that these practices are subject to review. A biting apparatus was used to create 66 bitemarks in human cadaver skin. The bitemarks were photographed, sized 1:1, and evaluated with Adobe Photoshop^®. Metric/angular measurements and hollow volume dental overlays were employed. Distortion produced was calculated and assessed. Results showed distortional ranges were nonuniform both between bites, as well as within each bite. Thus, enlarging/decreasing the photograph uniformly would not correct the distortion that resulted. With regard to bitemark profiling, 38% of the bites created patterns that could be misleading if profiled. Features were present/absent that were inconsistent with the biter’s dentition. Conclusions indicate bitemark profiling and arbitrary distortion compensation may be inadvisable.     

Discrepancies Between Youth and Mothers’ Perceptions of Their Mother–Child Relationship Quality and Self-Disclosure: Implications for Youth- and Mother-Reported Youth Adjustment

Recently, researchers have devoted greater attention to understanding how disagreement between mothers and their children regarding parent-child relationship quality and functioning impacts youth adjustment. While some view discrepancies as indices of developmentally appropriate individuation, discrepancies regarding family functioning also have been found to predict problematic youth functioning. This study examined the effects of mother-child discrepancies for mother-child relationship qualities and youth self-disclosure on youth- and mother-reported youth internalizing and externalizing adjustment. 232 fifth, eighth, and 11th grade youth (55?% female) and their mothers completed measures of mother-child relationship quality, youth self-disclosure, and youth internalizing and externalizing adjustment. For internalizing adjustment, few effects of discrepancy on adjustment were evident. Instead, informant-specific perceptions of mother-child relationship functioning were most relevant for informant-specific reports of youth adjustment. For youth externalizing adjustment, the magnitude of mother-child discrepancies for negative relationship quality and for youth self-disclosure predicted lower levels of problematic externalizing behavior from both the children's and the mothers' perspectives, which could indicate a lack of parent-child communication. Future research is needed to fully understand how discrepancies in negative or maladaptive aspects of mother-child relationships are formed (e.g., low disclosure), are understood by the members of the dyad, and contribute to the onset, maintenance, and treatment of problematic behavioral outcomes.     

Connecting Women's Histories: the local and the global

ABSTRACT

The articles in this Special Issue are drawn from some of the contributions to a conference held at Sheffield Hallam University, UK, from 29 August to 1 September 2013 titled ‘Women's Histories: the local and the global’. The articles reflect on diverse aspects of the entangled histories of women across the world, mainly, but not exclusively, during the twentieth century. They explore the range of ways in which women's history, international history, transnational history and imperial and global histories are interwoven.
