    Risk communication and community right to know: A public relations obligation to inform

    Risk communication and community right to know are increasingly important functions of public relations within communities that face a considerable amount of health, safety and environmental risk related to chemical manufacturing. Following Susan G. Hadden’s (1989) claim that community right to know is not only a legal subject but a powerful approach to risk communication and by extension public relations, this research project analyzed, through an ethnographic case study of participant observations (n=193 days), interviews (n=27) and focus groups (n=15), how community residents perceive and construct their awareness and understanding of significant federally mandated and industry initiated community-right-to-know initiatives within risk communication. Findings include a general lack of awareness and understanding of community-right-to-know programs and risk management protocols, with differences among communities, cultures and genders, and the social justification of risks via narratives

    Another part of the risk communicatin model: Analysis of risk communication process and message content

    The authors undertook a study to define the messages that exist in 2 communities of risk (e.g., high concentration of chemical facilities) using the principles of fantasy theme analysis and symbolic convergence theory. Through several methodological steps including a document review, interviews, focus groups, and a telephone survey (N = 450), the researchers determined the messages that dominate in the community, and were able to segment them into rhetorical visions based on master analogues. Analysis indicated that persons who adhere to different perspectives or opinions (measured as rhetorical visions) experience different amounts of uncertainty, control, and support or opposition for the industries that create the risks. This analysis adds depth to the risk communication literature and suggests that public relations practitioners can and should attempt to understand risk discourse content as well as the communication processes and risk perceptions held by key publics

    Emergency Text Messaging Systems and Higher Education Campuses: Expanding Crisis Communication and Chaos Theory

    Recent public safety threats affecting college and university campuses during episodes of natural disasters and mass violence have exposed numerous challenges and opportunities in risk and crisis communication. This study addresses how colleges and universities have incorporated emergency text messaging systems into their crisis communication plans; how these institutions have tested such emergency notification systems; and what, if any, prevalent gaps exist between audience expectations and actual practices. Using grounded theory, the data collected in this study through in-depth phone interviews (N=10) of university public relations practitioners, as well as a document analysis of media coverage of campus crises (N=36), offered a humanistic and constructivist perspective about circumstances related to emergency text message alert systems that few researchers have explored. The analysis of the data also revealed and confirmed that chaos theory can play a role as a significant theory and potentially guiding paradigm of crisis communications research

    Genome-wide investigation of light and carbon signaling interactions in Arabidopsis

    BACKGROUND: Light and carbon are two essential signals influencing plant growth and development. Little is known about how carbon and light signaling pathways intersect or influence one another to affect gene expression. RESULTS: Microarrays are used to investigate carbon and light signaling interactions at a genome-wide level in Arabidopsis thaliana. A classification system, 'InterAct Class', is used to classify genes on the basis of their expression profiles. InterAct classes and the genes within them are placed into theoretical models describing interactions between carbon and light signaling. Within InterAct classes there are genes regulated by carbon (201 genes), light (77 genes) or through carbon and light interactions (1,247 genes). We determined whether genes involved in specific biological processes are over-represented in the population of genes regulated by carbon and/or light signaling. Of 29 primary functional categories identified by the Munich Information Center for Protein Sequences, five show over-representation of genes regulated by carbon and/or light. Metabolism has the highest representation of genes regulated by carbon and light interactions and includes the secondary functional categories of carbon-containing-compound/carbohydrate metabolism, amino-acid metabolism, lipid metabolism, fatty-acid metabolism and isoprenoid metabolism. Genes that share a similar InterAct class expression profile and are involved in the same biological process are used to identify putative cis elements possibly involved in responses to both carbon and light signals. CONCLUSIONS: The work presented here represents a method to organize and classify microarray datasets, enabling one to investigate signaling interactions and to identify putative cis elements in silico through the analysis of genes that share a similar expression profile and biological function

    Involvement in surface antigen expression by a moonlighting FG-repeat nucleoporin in trypanosomes

    Components of the nuclear periphery coordinate a multitude of activities, including macromolecular transport, cell-cycle progression, and chromatin organization. Nuclear pore complexes (NPCs) mediate nucleocytoplasmic transport, mRNA processing, and transcriptional regulation, and NPC components can define regions of high transcriptional activity in some organisms at the nuclear periphery and nucleoplasm. Lineage-specific features underpin several core nuclear functions and in trypanosomatids, which branched very early from other eukaryotes, unique protein components constitute the lamina, kinetochores, and parts of the NPCs. Here we describe a phenylalanine-glycine (FG)-repeat nucleoporin, TbNup53b, that has dual localizations within the nucleoplasm and NPC. In addition to association with nucleoporins, TbNup53b interacts with a known trans-splicing component, TSR1, and has a role in controlling expression of surface proteins including the nucleolar periphery-located, procyclin genes. Significantly, while several nucleoporins are implicated in intranuclear transcriptional regulation in metazoa, TbNup53b appears orthologous to components of the yeast/human Nup49/Nup58 complex, for which no transcriptional functions are known. These data suggest that FG-Nups are frequently co-opted to transcriptional functions during evolution and extend the presence of FG-repeat nucleoporin control of gene expression to trypanosomes, suggesting that this is a widespread and ancient eukaryotic feature, as well as underscoring once more flexibility within nucleoporin function

    Right to know as a foundation for ethical practice: A reinterpreted and expanded public relations code of ethics.

    No full text
    This paper examines that while community right to know mirrors public relations ethics codes, the field falls short of its basic philosophy and tenets. Ultimately right to know as an ethical foundation for public relations moves current ethics codes beyond the sovereignty of consumer choice and concepts such as transparency
