Community Ecology and Capacity: Advancing Environmental Communication Strategies among Diverse Stakeholders

1. Introduction Many socioeconomically and geographically diverse communities in the United States have been challenged by occurrences of environmental contamination and the related complex public health issues. The investigations associated with such concerns have traditionally been the responsibility of governmental agencies. Communities facing potential environmental exposures often believe that government-based environmental agencies are not adequately addressing their concerns regarding risk, thus resulting in their misunderstanding and distrust of the regulatory process. A schism develops whereby the community perceives that government is either not doing enough to address their concerns and/or are being influenced by the relevant industry. The governmental agencies involved perceive that the community possesses an inaccurate or irrational perception of the potential risks. As a result, a stressful relationship often arises. Recommendations for effective risk communication have been developed and published (Covello & Sandman, 2001; Hance et al., 1989; Sandman, 1989). Research has also demonstrated the importance of developing relationships among stakeholders and its impact on information delivery and reception (ATSDR, 2004). Given that stakeholder groups perceive risk differently, it is imperative for each group to appreciate the viewpoints of all involved to engage in effective dialog (Park et al., 2001; Tinker et al., 2001). Cox (2006) defines environmental communication as “…the pragmatic and constitutive vehicle for our understanding of the environment as well as our relationships to the natural world; it is the symbolic medium that we use in constructing environmental problems and negotiating society’s different responses to them.” Although opportunities for public participation in environmental assessments have greatly increased, the environmental communication process among key stakeholders needs further evaluation (Charnley & Engelbert, 2005; McKinney & Harmon, 2002). The purpose of this chapter is to describe an evaluative process to develop and propose recommendations that could improve the environmental communication that occurs among diverse stakeholders, such as an environmental regulation and protection agency, waste disposal and energy producing facilities, community activists and the general public. Two case studies will be presented; the first describes the management of environmental permitting decisions in several disparate communities; and the second describes the management and perception of health risks from a single-owner waste-to-energy facility in two distinct communities. To accomplish this goal, this chapter will: 1.) examine how a state environmental agency and waste disposal and energy producing facilities describe their environmental communication experiences regarding various permitting operations and the risk perceptions of the impacted communities; 2.) identify effective communication methods; 3.) discuss the strengths and limitations of these activities; and 4.) propose recommendations for practitioners to advance environmental communication strategies among these key stakeholders

Advancing Dispute Resolution by Unpacking the Sources of Conflict: Toward an Integrated Framework

Organizational leaders, public policy makers, dispute resolution professionals, and scholars have developed diverse methods for resolving workplace conflict. But there is inadequate recognition that the effectiveness of a dispute resolution method depends on its fit with the source of a particular conflict. Consequently, it is essential to better understand where conflict comes from and how this affects dispute resolution. To these ends, this paper uniquely integrates scholarship from multiple disciplines to develop a multi-dimensional framework on the sources of conflict. This provides an important foundation for theorizing and identifying effective dispute resolution methods, which are more important than ever as the changing world of work raises new issues, conflicts, and institutions

INTERNET ADOPTION AND USE OF E-COMMERCE STRATEGIES BY AGRIBUSINESS FIRMS IN ALABAMA

Electronic commerce (e-commerce) is relatively new to the agricultural industry, and affects such aspects of the organization as its strategy, processes, customer relationships, information technology, and business culture. This paper analyzes the factors influencing agribusiness firms' desire or need to adopt the Internet and employ e-commerce strategies. The relationship between the factors driving the choice of distribution channel and Internet usage for e-commerce will empirically be estimated. This study will also assess how Internet adoption and the use of e-commerce strategies impact rural development and the overall sustainability paradigm.Agribusiness,

Separation of bacterial spores from flowing water in macro-scale cavities by ultrasonic standing waves

The separation of micron-sized bacterial spores (Bacillus cereus) from a steady flow of water through the use of ultrasonic standing waves is demonstrated. An ultrasonic resonator with cross-section of 0.0254 m x 0.0254 m has been designed with a flow inlet and outlet for a water stream that ensures laminar flow conditions into and out of the resonator section of the flow tube. A 0.01905-m diameter PZT-4, nominal 2-MHz transducer is used to generate ultrasonic standing waves in the resonator. The acoustic resonator is 0.0356 m from transducer face to the opposite reflector wall with the acoustic field in a direction orthogonal to the water flow direction. At fixed frequency excitation, spores are concentrated at the stable locations of the acoustic radiation force and trapped in the resonator region. The effect of the transducer voltage and frequency on the efficiency of spore capture in the resonator has been investigated. Successful separation of B. cereus spores from water with typical volume flow rates of 40-250 ml/min has been achieved with 15% efficiency in a single pass at 40 ml/min.Comment: 11 pages, 6 figure

Use of Antipsychotic Medications in Individuals With Alzheimer\u27s Disease in Nursing Facilities

Patients with Alzheimer\u27s disease or other types of dementia often require long-term care in nursing facilities (NF) where they may display out-of-character behaviors complicating their care. While antipsychotic medications are sometimes prescribed for NF residents, their use is considered inappropriate for the control of dementia behaviors. The Centers for Medicare and Medicaid Services have rated Texas the worst state in the country for the inappropriate use of antipsychotic medications for NF residents with dementia. This project was guided by the star model of knowledge transformation with the goal to reduce inappropriate use of antipsychotic medications through NF staff education. The purpose of this project was to develop an educational program for nurses, direct care staff, pharmacists, and prescribers regarding appropriate use of antipsychotic medications, reduction efforts, alternative non pharmacological interventions, and an associated toolkit of educational resources. The program development was accomplished in conjunction with a team of local experts who provided process evaluation regarding their satisfaction with the planning process through the completion of an anonymous, 10-question, Likert-type survey. All participants scored their results with a (5) strongly agree or (4) agree. A descriptive analysis of the survey data provided information that positively supported the development of the project. At the end of the project, the education program and resources were delivered to the Texas Health and Human Services Commission, with a plan for later implementation and outcome evaluation. This project has the potential to achieve positive social change through reducing the numbers of Texan NF residents with dementia who are inappropriately prescribed antipsychotic medications, which will result in an increase in their quality of life

Vortex Fluctuations in the Critical Casimir Effect of Superfluid and Superconducting Films

Vortex-loop renormalization techniques are used to calculate the magnitude of the critical Casimir forces in superfluid films. The force is found to become appreciable when size of the thermal vortex loops is comparable to the film thickness, and the results for T < Tc are found to match very well with perturbative renormalization theories that have only been carried out for T > Tc. When applied to a high-Tc superconducting film connected to a bulk sample, the Casimir force causes a voltage difference to appear between the film and bulk, and estimates show that this may be readily measurable.Comment: 4 pages, 5 figures, Revtex 4, typo correctio

Nonlinear Competition Between Small and Large Hexagonal Patterns

Recent experiments by Kudrolli, Pier and Gollub on surface waves, parametrically excited by two-frequency forcing, show a transition from a small hexagonal standing wave pattern to a triangular ``superlattice'' pattern. We show that generically the hexagons and the superlattice wave patterns bifurcate simultaneously from the flat surface state as the forcing amplitude is increased, and that the experimentally-observed transition can be described by considering a low-dimensional bifurcation problem. A number of predictions come out of this general analysis.Comment: 4 pages, RevTex, revised, to appear in Phys. Rev. Let

Factors Influencing Yield Management of Pinot Noir Vineyards in Oregon

Oregon\u27s wine grape industry uses yield targets to achieve quality in Pinot Noir vineyards, and this practice has led to increases in cost of production. A multiapproach study was conducted to investigate how vineyard target yields are set, why yield thresholds exist, and who influences decisions related to vineyard target yields. Growers suspect that higher yields are possible without compromising quality, but they are unable to change yield targets due to winery and buyer decision making. To be effective in eliciting change and realizing impact, Extension educators need to do targeted outreach to buyers and wine makers in addition to growers and consider participatory research

Heterodyne detection of the 752.033-GHz H2O rotational absorption line

A tunable high resolution two stage heterodyne radiometer was developed for the purpose of investigating the intensity and lineshape of the 752.033 GHz rotational transition of water vapor. Single-sideband system noise temperatures of approximately 45,000 K were obtained using a sensitive GaAs Schottky diode as the first stage mixer. First local oscillator power was supplied by a CO2 laser pumped formic acid laser (761.61 GHz), generating an X-band IF signal with theoretical line center at 9.5744 GHz. Second local oscillator power was provided by means of a 3 GHz waveguide cavity filter with only 9 dB insertion loss. In absorption measurements of the H2O taken from a laboratory simulation of a high altitude rocket plume, the center frequency of the 752 GHz line was determined to within 1 MHz of the reported value. A rotational temperature 75 K, a linewidth 5 MHz and a Doppler shift 3 MHz were measured with the line-of-sight intersecting the simulated-plume axis at a distance downstream of 30 nozzle diameters. These absorption data were obtained against continuum background radiation sources at temperatures of 1175 and 300 K
