DESIRED AND ACHIEVED OUTCOMES IN FEDERAL WATER RESOURCES PLANNING1

ABSTRACT Local or project level planning occurs within most federal water resources programs. Such planning involves both federal and local participants, and commonly involves a range of interest groups. It is necessary to know what goals these participants believe the planning process ought to achieve in order to design planning procedures which will meet their expectations. Social judgment analysis was used to elicit those goals for respondents who had participated in one of five different federal water resources programs, in one of five different roles. Respondents also evaluated the extent to which the planning activities in a recent project in which they had participated had actually attained the posited goals. The respondents believed that responsiveness to local problems was significantly more important than resolving conflicts or increasing public understanding. A fourth goal, achieving national objectives, was believed to be less important than the other three. No significant differences in these goal evaluations were associated with the type of program in which the respondents had participated. However, there were significant differences associated with the respondent's role in the planning process. Respondents' ratings of the effectiveness of actual planning projects varied by both program and respondent role.     

ANALYSIS OF HYDRILLA-INHIBITING FRACTIONS IN NATURAL WATERS: THE CONCEPT OF “FINGERPRINTING” THROUGH LIQUID CHROMATOGRAPHY1

ABSTRACT: High performance liquid chromatography (HPLC) has been used to identify a fraction of aqueous sediment extract from Lake Starvation, Hillsborough County, Florida, that is responsible for inhibition of hydrilla growth. The fraction was separated on a Zorbax? C₁₈ preparative-scale column. The present study examines various lake sediment extracts and river water samples to determine the presence or absence of the inhibitor peak. The biologically active component is absent in certain rivers where hydrilla is prominent, but it is present in extracts of Lake Starvation and White Trout Lake sediments that are known to have hydrilla growth inhibiting properties. The implications of “fingerprinting” natural waters for hydrilla inhibitor through liquid chromatography are considered.     

The organizational tenure — Job involvement relationship: A job-career experience explanation

Research on the job involvement-organizational tenure relationship has shown no consistent relationship, but recent job and career experience models suggest that a relationship should be found. Using data from three organizations (n = 216), polynomial regression analysis revealed a curvilinear job involvement-organizational tenure relationship. This finding is discussed with reference to changes in workplace sensemaking that occur as work experience is accumulated.     

Keeping the Books for Environmental Systems: An Emergy Analysis of West Virginia

Emergy provides a general accounting mechanism that allows us to view the economy and the environment on the same income statement and balance sheet. This allows an auditor to verify the economic picture by checking it against a more complete representation of the flows and storages of real wealth as measured by emergy. In this study, we constructed emergy accounts for the state of West Virginia in 1997. The income statement showed annual production, consumption, and flows of emergy and dollars into and out of the state. The balance sheet evaluated the storage of emergy in some of the state's assets. Emergy indices were used to answer questions posed by managers and gain insight into the state's economic and environmental strengths and weaknesses. West Virginia has great wealth in nonrenewable resources (9E14 sej m-2 or 17 times the U.S. average). The investment ratio of emergy purchased outside to indigenous renewable and nonrenewable emergy was 2.2:1, which indicates a high potential for future development. However, the environmental loading ratio (14:1) was already 1.5 times higher than that found at an average location in the U.S. Twice as much emergy was exported as received and standard of living indicators showed that people have largely failed to benefit from their state's wealth. We propose that, just as in business, where decisions made using financial accounts ensure solvency; decisions governing the environment should be made based on an emergy accounting of activities, assets, and liabilities for the combined system of humanity and nature.     

A corporate approach to social monitoring and assessment for development in a fragile environment

The prevailing corporate trend regardingdevelopment of energy resources in the tropics emphasizesfinancial gain over long-term societal benefits. Somecorporations are beginning to find a competitive advantage linkedto proactive relations with host communities and adequateprotection of fragile ecosystems. Herein, we describe a casestudy where an international energy production company workedwith stakeholders to achieve social capital and sustainabledevelopment. The strategies aimed to strengthen local capacity toimprove social welfare and to ensure conservation and wise use ofbiodiversity. We provide examples, discuss lessons learned andmake recommendations for future development projects.     

Analysis of Flax and Cotton Fiber Fabric Blends and Recycled Polyethylene Composites

Manufacturing composites with polymers and natural fibers has traditionally been performed using chopped fibers or a non-woven mat for reinforcement. Fibers from flax (Linum usitatissimum L.) are stiff and strong and can be processed into a yarn and then manufactured into a fabric for composite formation. Fabric directly impacts the composite because it contains various fiber types via fiber or yarn blending, fiber length is often longer due to requirements in yarn formation, and it controls the fiber alignment via weaving. Composites created with cotton and flax-containing commercial fabrics and recycled high-density polyethylene (HDPE) were evaluated for physical and mechanical properties. Flax fiber/recycled HDPE composites were easily prepared through compression molding using a textile preform. This method takes advantage of maintaining cotton and flax fiber lengths that are formed into a yarn (a continuous package of short fibers) and oriented in a bidirectional woven fabric. Fabrics were treated with maleic anhydride, silane, enzyme, or adding maleic anhydride grafted polyethylene (MAA-PE; MDEX 102-1, Exxelor^® VA 1840) to promote interactions between polymer and fibers. Straight and strong flax fibers present problems because they are not bound as tightly within yarns producing weaker and less elastic yarns that contain larger diameter variations. As the blend percentage and mass of flax fibers increases the fabric strength, and elongation generally decrease in value. Compared to recycled HDPE, mechanical properties of composite materials (containing biodegradable and renewable resources) demonstrated significant increases in tensile strength (1.4–3.2 times stronger) and modulus of elasticity (1.4–2.3 times larger). Additional research is needed to improve composite binding characteristics by allowing the stronger flax fibers in fabric to carry the composites load.     

Victoria's emerging framework of regional governance for sustainability: the case of catchment management authorities and regional catchment strategies

The aim of this paper is to presents a progress report on how a subnational jurisdiction, the Australian state of Victoria, is attempting to implement regional governance for sustainability through its catchment planning framework. The paper examines the lessons learnt from a best practice approach to the implementation of network governance to see whether there are actions that can be taken to improve regional governance for sustainability in Victoria. The authors argue that Victoria is implementing a network governance approach to natural resource management (NRM) as a significant component of sustainability and that this has certain advantages. In particular the emergence of Regional Catchment Strategies developed by the State's ten statutory Catchment Management Authorities as 'regional sustainability blueprints' is bringing a significant level of maturity to the state's governance framework. Furthermore the state is currently working to complete its governance for sustainability through new statewide integrating frameworks—an Environmental Sustainability Framework as well as a statewide Catchment Management and Investment Framework. The paper concludes that taking a network governance approach could have transformative potential but there are significant challenges ahead: the complex task of aligning of national, state, catchment and local government strategies through an outcomes focus; the scarcity of mechanisms and tools to assist in translation of strategies into integrated investment priorities; gaps in knowledge and understanding of natural resource management problems; limitations in the capacity of regional and local bodies, including local government; and getting the policy tools right within the framework. However, as the best practice examples illustrate, taking a gradual approach to the development of the institutions—building on successive wins in capacity—is the best and only way to proceed.     

Mercury contamination: A human tragedy

Historically, the element, mercury, has been widely applied in industry, agriculture, and medicine. The role of mercury in technological progress and therapeutic benefits has generally been quickly accepted despite sketchy trial-and-error methods used to evaluate its overall impact. The discovery of the negative side effects of mercury, such as degradation of the environment and the accompanying threat to human health, has often been overlooked, sometimes for centuries. Mercury Contamination: A Human Tragedy (Wiley-Interscience 1977) describes both historical and current applications of quicksilver, the impact on human beings and the environment, and the social and legal efforts to reform the abuses. The following exerpts are taken from the impact of mercury on human beings and the environment in various parts of the world.
