Contextual and Audience Moderators of Channel Selection and Message Reception of Public Health Information in Routine and Crisis Situations

A richer understanding of audience channel selection and message reception during routine and crisis situations through receiver-oriented research offers great promise to extend situational theory's predictive utility. Key variables of situational theory, including involvement, constraint, and problem recognition in information seeking and processing may be moderated by broader demographic and contextual factors in consumption of health information. Thus, situational theory frames this analysis of channels most important for public use in routine and crisis contexts in health information seeking, differences in preferences between contexts, and the criteria publics apply when evaluating the quality of health information. Results of a national random telephone survey (n = 400) indicate a need for more receiver-based studies in public relations, as involvement and demographics played key moderating roles in channel preferences. Use of several channels including radio, magazine, and television differed between crisis and routine contexts for health information consumers. In both crisis and routine contexts, those with high health involvement were more likely to use active media channels such as newspapers and magazines. Perceived accuracy is also revealed as a key criterion in evaluating the quality of health information consumers receive.     

The ecology of race and socioeconomic distress: infant and working-age mortality in Chicago

We examine the effects of education, unemployment, and racial segregation on age-, sex-, and race-specific mortality rates in racially defined Chicago community areas from 1989 to 1991. Community socioeconomic factors account for large observed areal variations in infant and working-age mortality, but especially working-age mortality for the black population. For black men, the mortality consequences of living in economically distressed communities are quite severe. Segregation effects on mortality are more modest and largely operate through neighborhood socioeconomic conditions, although some direct effects of segregation on mortality for blacks are apparent.     

Posttraumatic Stress and Mental Health Functioning of Sexually Abused Children

This study examined the relationship between levels of posttraumatic stress and overall mental health functioning of fifty-three sexually abused children. This study analyzes the relationships between the mental health functioning of sexual abuse victims and PTSD, using data collected from the Non-Offending Parents Project. Unlike numerous earlier studies, standardized instruments (the Child Assessment Schedule and the Child Posttraumatic Stress Reaction Index) were used for data collection. Data analysis supported the hypothesis that the posttraumatic stress level of children who have been sexually abused is associated with level of child mental health functioning. Nearly all the children in the study were experiencing a clinical level of posttraumatic stress, and were diagnosed as having PTSD. Child Assessment Schedule subscale areas which were related to posttraumatic stress level included worries, physical complaints, moods, school functioning, family, and fears.     

#Boycottautismspeaks: communicating a counternarrative through cyberactivism and connective action

A growing body of research is examining the role of cyberactivism in facilitating social movements. Yet, few have considered the interplay between cyberactivism and disability advocacy. Through a case study of the #boycottautismspeaks movement, this study finds that cyberactivism may provide platforms for self-advocates to connect through bridging and bonding in unique ways that draw together and give voice to individuals who otherwise may not have means for such dynamic engagement. Drawing on a sample of approximately 10,000 tweets that circulated with the #boycottautismspeaks hashtag, this research applies thematic analysis and the Social Identity Model of Deindividuation Effects to reveal how counternarratives of disability are developed and circulated via cyberactivism. Findings reveal that #boycottautismspeaks contributors communicated to enhance bonding through (a) (dis)identification, (b) collaboration, and (c) creative resistance. In addition, they communicated to facilitate bridging by (a) demonstrating morality, (b) appealing to humanity, and (c) aligning with other causes. The #boycottautismspeaks movement melded the logic of collective and connective action, provided opportunities for both coordinated and self-directed activity, developing a network of networks through various stitching mechanisms, and cultivating an affective public. Implications for cyberactivism research and practice as well as disability advocacy are discussed.     

Are crisis communicators practicing what we preach?: An evaluation of crisis response strategy analyzed in public relations research from 1991 to 2009

Quantitative content analysis is used to evaluate crisis response strategy analyzed in more than 18 years of research published in crisis communication literature in public relations to reveal its effectiveness, nature, and contextual application. Analysis of 51 articles published in 11 different journals using two dominant theories in public relations crisis communication literature, Benoit's Image Restoration Theory and Coombs’ Situational Crisis Communication Theory, indicates a lack of diversity in cases analyzed by scholars, gaps between theory and practice, and pressing directions for future research in crisis communication.     

Procurement process: Decision by exclusion and pairwise comparisons

Two case studies illustrate multicriteria decision making techniques frequently used in procurement practice: least-cost sufficient performance and weighted utility optimization. Both techniques have defects and are rarely robust. Decision by exclusion and pairwise comparisons is proposed as a third approach which eliminates inferior alternatives by generalized forms of minimum performance requirements established under multicriteria framework. It is more robust and maintains high level of accountability.     

Urban growth and population densities

Differences in the distribution of population within and across metropolitan areas are seen as a product of the development of the metropolis during different transportation epochs. Age cohorts of census tracts in Cleveland, Ohio, may be split into three groups of development patterns based on the time of their early development: (1) before the development of the automobile, (2) during the early period of the auto’s diffusion to the population, and (3) during the period of the mass diffusion of the auto. Patterns of population concentration and congestion across metropolitan areas are heavily selective of places with large population growth before the development of the streetcar and the automobile. More recent population growth has had little effect on population congestion but has led to a deconcentrated metropolis.
