Bribing Biodiversity: Corruption, Participation, And Community-Based Management In Venezuela, Brooke Ann Zanetell, Barbara A. Knuth Dec 2002

Bribing Biodiversity: Corruption, Participation, And Community-Based Management In Venezuela, Brooke Ann Zanetell, Barbara A. Knuth

Journal of Rural Social Sciences

Widespread alarm over the continuing decline of marine and freshwater fisheries has prompted research on the theory and practice of community-based management (CBM). Considering the suite of possible CBM benefits--including local involvement, compliance with regulations, reduced enforcement costs, and sustainable resource use--it is understandable that CBM projects are on the rise. However, there is insufficient examination of the challenges to CBM and the context-specific feasibility of grassroots stewardship. In response, we applied an assessment framework to a Venezuelan fishery to evaluate the feasibility of CBM and to identify barriers to its fruition. We used a variety of methods in concert …

Passing The Cluck, Dodging Pullets: Corporate Power, Environmental Responsibility, And The Contract Poultry Grower, Joseph J. Molnar, Thomas Hoban, Gail Brant Dec 2002

Passing The Cluck, Dodging Pullets: Corporate Power, Environmental Responsibility, And The Contract Poultry Grower, Joseph J. Molnar, Thomas Hoban, Gail Brant

Journal of Rural Social Sciences

Broiler production is concentrated in a few southem states where farmers are highly dependent on contract arrangements for income and livelihood. Poultry is the first animal industry to industrialize and its model of contract farming has been emulated by other animal industries. Environmental standards are becoming increasingly stringent and many farmers are faced with crossroad decisions about investments in dead bird and manure disposal facilities. Asymmetrical power relationships shift waste management responsibilities to growers in a number of ways. This paper details maneuvers poultry integrators use to avoid environmental risk and transfer it to their contract growers. Corporations "pass the …

Lagoons, Litter, And The Law: Cafo Regulation As Social Risk Politics, Larry L. Burmeister Dec 2002

Lagoons, Litter, And The Law: Cafo Regulation As Social Risk Politics, Larry L. Burmeister

Journal of Rural Social Sciences

The restructuring of the animal agriculture industry in the United States, a response to globalization dynamics within the world economy, has created a new social risk profile which did not exist in this industry prior to the adoption of factory farm technology. Analysis of the CAFO [concentrated animal feeding operation] regulation debate in Kentucky illustrates the political economy genesis of social risk politics accompanying this new technology. The politics of regulatory efforts to ameliorate such risk, an increasingly frequent occurrence in the risk society era, are examined in a recent attempt to promulgate a CAFO regulatory regime in Kentucky. This …

An Invariance Transformation Algorithm For Defect Characterization Of Ultrasonic Signals For The Nondestructive Evaluation Of Concrete, Michael Dominic Ciocco Dec 2002

An Invariance Transformation Algorithm For Defect Characterization Of Ultrasonic Signals For The Nondestructive Evaluation Of Concrete, Michael Dominic Ciocco

Theses and Dissertations

Nondestructive evaluation (NDE) techniques offer cost-effective strategies for monitoring the integrity of a variety of civil infrastructure, such as natural gas and sewer pipelines, without the need to take the system off-line. However, interpretation of NDE signals in terms of the location, size, and shape of underlying flaws in the material being inspected is fraught with difficulty. Typically, variations in the testing signal due to operational parameters have created a significant challenge for defect characterization. This thesis proposes, develops, and validates a defect characterization algorithm that compensates for operational variables and maps the test signal to a visual defect profile. …

Natural Fire Regime: A Guide For Sustainable Management Of The Canadian Boreal Forest, Yves Bergeron, Alain Leduc, Brian D. Harvey, Sylvie Gauthier Dec 2002

Natural Fire Regime: A Guide For Sustainable Management Of The Canadian Boreal Forest, Yves Bergeron, Alain Leduc, Brian D. Harvey, Sylvie Gauthier

Aspen Bibliography

The combination of certain features of fire disturbance, notably fire frequency, size and severity, may be used to characterize the disturbance regime in any region of the boreal forest. As some consequences of fire resemble the effects of industrial forest harvesting, conventional forest management is often considered as a disturbance that has effects similar to those of natural disturbances. Although the analogy between forest management and fire disturbance in boreal ecosystems has some merit, it is important to recognise that it also has its limitations. Short fire cycles generally described for boreal ecosystems do not appear to be universal; rather, …

Assessment Of Wind Energy Potential For Eletricity Generation In Setchet, Hanang, Tanzania, A. S. Kasasi, R. M. Kainkwa Dec 2002

Assessment Of Wind Energy Potential For Eletricity Generation In Setchet, Hanang, Tanzania, A. S. Kasasi, R. M. Kainkwa

Tanzania Journal of Science

Tanzania depends heavily on hydropower for her electricity demand and experiences power shortage during the dry seasons. Wind energy is proposed as an alternative source of electricity to the fossil fuel generators during the dry season, the latter are normally used to supplement the shortfall in hydro-electricity generation. Fossil fuel generators produce emissions that are toxic and as such degrade the environment. Wind speed data from a site called Setchet is used to illustrate that the available wind energy can be harvested to generate electricity that can supplement the shortfall of electricity. The windy season, which is from July to …

Morphometrics Of The Pancake Tortoise (Malacochersus Tornieri) In Tanzania, J. Kabigumila

Tanzania Journal of Science

Observations were made of the morphometrics of captive pancake tortoise (Malacochersus tornieri) in June 1995. Carapace length ranges for immature tortoises and adult males and females were 50-115, 123-160 and 129-171 mm respectively. The respective carapace widths were 45-90, 97-130, and 92-129 and 97-130 mm. Carapace height ranges were 15-29, 25-40 and 117-159 mm, respectively, while plastron length ranges were 45-110, 108-150 and 117-159 mm. The relationships between carapace length and width (males: y = 13.763+0.639x; females: y = 17.302+0.639x) and height (males: y=6.851+0.170x, females: y = 17.274+0.170x) were isometric and sexually dimorphic in adults. The relationship between carapace length …

Sexual Dimorphism In The Mandibles Of A Homogenius Black Population Of Tanzania, F. M. Fabian, R. Mpembeni Dec 2002

Sexual Dimorphism In The Mandibles Of A Homogenius Black Population Of Tanzania, F. M. Fabian, R. Mpembeni

Tanzania Journal of Science

Mandibles of known age and gender from cadavers of Tanzanian Bantu population were studied to determine if the human mandible could be sexually dimorphic in a homogenous population. All mandibles were measured using electronic two-digit millimetre veneer calliper. All of the male (100%) and 96% of the female mandibles were positively sexed. The present study indicates that the mandible of the Tanzanian Bantu population possesses metric parameters that make it sexually dimorphic. More studies, involving other Tanzanian groups, might reveal racial or ethnic differences based on mandibular morphometrics.

Absolute Migration And The Evolution Of The Rodriguez Triple Junction Since 75 Ma, D. C. P. Masalu Dec 2002

Absolute Migration And The Evolution Of The Rodriguez Triple Junction Since 75 Ma, D. C. P. Masalu

Tanzania Journal of Science

The Rodriguez Triple Junction (RTJ) is a junction connecting three mid-ocean ridges in the Indian Ocean: the Southwest Indian Ridge (SWIR), the Central Indian Ridge (CIR) and the Southeast Indian Ridge (SEIR). The evolution of the RTJ has been studied extensively for the past 10 Ma and the triple junction is believed to be largely a ridge-ridge-ridge (RRR) triple junction. However, due to the scarcity of data, its configuration prior to that period is poorly understood. The migration of the RTJ in the hotspot reference frame, for the past 75 million years has been mapped, by reconstructing its traces on …

Mechanistic Studies Of Carbon Steel Corrosion Inhibition By Cashew Nut Shell Liquid, J Y N Philip, J Buchweishaija, L L Mkayula Dec 2002

Mechanistic Studies Of Carbon Steel Corrosion Inhibition By Cashew Nut Shell Liquid, J Y N Philip, J Buchweishaija, L L Mkayula

Tanzania Journal of Science

The inhibition mechanism of the Cashew Nut Shell Liquid (CNSL) on SAE 1008 carbon steel corrosion in CO 2  saturated 3% NaCl solutions has been studied by weight loss, UV/VIS and electrochemical techniques. The phenoxide, R-Ar-O- ions from the CNSL inhibitor were found to be responsible for the reduction of the corrosion rate of the carbon steel. Also, it was observed that the surface charge of the carbon steel electrodes was positive with respect to the solutions containing CNSL inhibitor. It is likely that the mechanism of the CNSL inhibitor adsorption involved the electrostatic attraction between the positively charged metal …

Optimal Pumping Strategies For Umatilla Chemical Depot Rdx And Tnt Plumes, Richard C. Peralta Dec 2002

Optimal Pumping Strategies For Umatilla Chemical Depot Rdx And Tnt Plumes, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

We present optimal pumping strategies to address RDX and TNT plumes at Umatilla Chemical Depot (UCD). We provide strategies for four optimization problem formulations. Each strategy requires constructing 2 wells. New Well U-1 is in the same location for all strategies. The second well location can differ with formulation. The number in a strategy’s name refers to the formulation it addresses. Using optimization in design is normally an iterative process involving interaction between the designer and client after preliminary optimizations are performed. This project does not permit that. To compensate, we present a second strategy for Formulation 1 (Strategy USU1B), …

Computer Attacks On Critical National Infrastructure: A Use Of Force Invoking The Right Of Self-Defense, Eric Talbot Jensen Dec 2002

Computer Attacks On Critical National Infrastructure: A Use Of Force Invoking The Right Of Self-Defense, Eric Talbot Jensen

Faculty Scholarship

Computer networks create tremendously increased capabilities but also represent equally increased vulnerabilities. These vulnerabilites are especially acute in relation to potential attacks on critical national infrasturucture. This Article proposes that international law must evolve to recognize that attacks against a nation's critical national infrastructure from any source constitute a use of force. Such attacks, therefore, give the victim state the right to proportional self-defense - including anticipatory self-defense - even if the computer network attack is not an armed attack under Article 51 of the United Nations Charter. Due to the instantaneous nature of computer network attacks, the right to …
