Natural Resources, Gender And Leadership, Smita Premchander

IIMB Management Review

Sustainable management of resources presents a great challenge and calls for strong leadership. Leaders are important as agents of change. They are able to motivate and increase the confidence of people, so that change can be achieved in organisations and in society. Leadership skills were once thought to be inborn but now it is recognised that they can be developed . The study of leadership has generated a vast amount of literature, most of which is in the context of organisational management. Most leadership theories are drawn from the corporate sector and their experiences.

Optimization Of Palladium-Catalyzed In Situ Destruction Of Trichloroethylene-Contaminated Groundwater Using A Genetic Algorithm, Manuel Fernandez

Theses and Dissertations

Conventional technologies for the treatment of groundwater contaminated with chlorinated solvents have limitations that have motivated development of innovative technologies. One such technology currently under development involves using palladium-on-alumina (Pd/Al) as a catalyst to promote dechlorination. Pd/Al catalyst may be used in-well as part of a re-circulating horizontal flow treatment well (HFTW) system. An HFTW system involves two or more dual-screened wells, with in-well reactors, to capture and treat contaminated groundwater without the need to pump the water to the surface. In this study, objective and fitness functions, based on system costs and TCE concentration requirements, were developed to optimize …

Dissolution Of Chromium From Inhalable Primer Paint Particles Into A Simulated Lung Fluid, David A. Kauth

Theses and Dissertations

The use of chromate as a corrosion inhibitor in primer paint is an essential component for the protection of aluminum-skinned aircraft and the primary source of hexavalent chromium (Cr (VI)) exposure to USAF aircraft painters. The objective of this research was to quantify the dissolution of chromate from freshly sprayed paint particles into a simulated lung fluid (SLF). Two primer paints were sprayed with a paint spray gun to generate overspray particles for collection into impingers filled with SLF. Particles were allowed to soak in SLF for 24 and 48 hours and then the particles were removed by centrifugation. The …

Lifecycle Energy And Air Emission Differences Between Electric And Internal Combustion Vehicles, David L. Mccleese

Theses and Dissertations

The U.S. Federal Government has encouraged shifting from internal combustion engine vehicles (ICEVs) to electric vehicles (EVs) with three objectives, reducing foreign oil dependence, greenhouse gas emissions, and criteria pollutant emissions. This thesis uses Monte Carlo simulation to predict lifecycle emissions and energy consumption differences per kilometer driven from replacing ICEVs with three EV options: lead acid, nickel cadmium (Ni-Cd), and nickel metal hydride (NiMH). All three EV options reduce U.S. foreign oil dependence by shifting to domestic coal. The probabilities that lifecycle energy consumption per km driven improve are lead acid 76%, Ni-Cd 64%, and NiMH 90%. The probabilities …

Determining The Value Of Groundwater Contamination Source Removal: A Methodology, Benjamin C. Recker

Theses and Dissertations

Subsurface contamination by industrial chemicals is one of the most prevalent and costly environmental problems facing the United States government. This contamination problem must be managed to protect human health and the environment. Two basic strategies are used to deal with subsurface contamination: source removal and contaminant containment. While much cost and performance data are available for individual technologies associated with each of these strategies, there have been very few studies that have examined the benefits of implementing source removal technologies in order to reduce contaminant containment (and hopefully total) costs. This study examines the tradeoff between extent of source …

Effects On The Red-Cockaded Woodpecker From Various Spatial And Temporal Applications Of Management Practices, Chad F. Schroeder

Theses and Dissertations

The Red-Cockaded Woodpecker (RCW) is an endangered species endemic to southeastern pine forests in the United States. RCWs are cooperative breeding birds that live together in clusters of old-growth pine trees in which they construct their nesting cavities. The cavities are constructed in living pines, which are predominantly longleaf pines. RCWs also forage upon older pines, preferably longleaf pine. The Endangered Species Act, along with other DoD regulations, requires DoD installations to protect the RCWs and restore their habitat. A popular management practice converts off-site (non-native) pines back to a region's indigenous pines. Conversion provides the best long term RCW …

Bear Behavior In The Vicinity Of Supplemental Feeding Stations In Western Washington, Dale L. Nolte, Timothy J. Veenendaal, George J. Ziegltrum, Philipp Fersterer

United States Department of Agriculture Wildlife Services: Staff Publications

Black bear can inflict severe negative Impacts on timber stands in the northwestern United States. A supplemental feeding program to provide bears an alternative food source during spring is practiced in the stat e of Washington, and to a lesser extent in other states. We initiated concurrent studies to assess characteristics of bear that forage at feeding stations, the interactions of bears around feeders, and impacts of the program on bear territories. Numerous bears fed at stations, including females with and without cubs, yearlings. and males. Bear feeding bouts at stations were generally short, less than 15 minutes. Bears generally …

A Model For Palladium Catalyzed Destruction Of Chlorinated Ethenes In Contaminated Groundwater, Christopher M. Stoppel

Theses and Dissertations

Groundwater contamination by chlorinated ethenes is a widespread environmental problem. Conventional remediation technologies have shortcomings that have prompted further research into the development of novel treatment technologies. A palladium/ alumina catalyst in the presence of dissolved molecular hydrogen (referred to hereafter as a PD/H₂ system) has been demonstrated to rapidly destroy chlorinated ethene contaminated groundwater. First-order kinetics have been used to model chlorinated ethene destruction in a PD/H₂ reactor. However, catalyst deactivation and regeneration are important processes that also need to be modeled in order to better understand their effect on treatment efficiency. This study presents a model …

Quantitative Validation Of A Model Of Chlorinated Ethene Natural Attenuation, Harold C. Young

Theses and Dissertations

Chlorinated ethenes are among the most prevalent groundwater contaminants at hazardous waste sites nationwide. In an attempt to manage the risks posed by these contaminants, while controlling costs, monitored natural attenuation (MNA) is being considered as a remediation strategy at many sites. MNA relies on naturally occurring physical, chemical, and biological processes in the subsurface to reduce the risk posed by the contamination. The implementation of MNA, however, requires a detailed understanding of these processes, and how they impact contamination at a particular site. One way to gain this understanding is through contaminant fate and transport modeling. In this study, …

Frame, Michael J. Hooper, Clyde F. Martin, Scott T. Mcmurry, Reynaldo Patino, Ernest E. Smith, Christopher W. Theodorakis

United States Department of Agriculture Wildlife Services: Staff Publications

The field of environmental toxicology, particularly as related to the area of ecotoxicology, continues to be a rapidly developing discipline of environmental science (Connell and Miller, 1984; Duffus 1980; Guthie and Perry, 1980; Hoffman et al., 1995; Moriarity 1988; Truhaut, 1977). The term ecotoxicology was introduced by Truhaut in 1969 (Truhaut, 1977) and this field is a natural extension of toxicology. It is best defined as the study of the fate and effects of toxic substances on an ecosystem and is based on scientific research employing both field and laboratory methods (Kendall, 1982; Kendall, 1992; and Hoffman et al., 1995). …

Guidelines For Eradication Of Terrestrial Vertebrates: A European Contribution To The Invasive Alien Species Issue, Piero Genovesi Ph.D.

Other Publications in Wildlife Management

Invasive alien species (IAS) are now acknowledged as one of the major threats to biodiversity, together with habitat loss and fragmentation. Furthermore, it is predicted that biotic invasions will become the major engines of ecological disintegration in the future; this is because of the increased spread of alien species, due to the greater mobility of the human population, rapidly growing transport technology, expanding tourism and travel activities, and world-wide free trade (Cox 1999, Ruesink et al. 1995).

In addition to the threats to biodiversity, the direct costs of IAS are immense. It is difficult to estimate precisely the economic losses …

A Strategic Marketing Analysis Of The Western Australian Olive Industry, Francis D'Emden

Horticulture published reports

A recent survey of Western Australian olive growers has revealed the rapid expansion of the State's Olive Industry, with at least 1.7 million olive trees to be planted in the next two to four years in Western Australia. NSW and SA are currently the dominant producers with around 64% of olive trees planted in those States.

This analysis concentrates on the olive oil market, as most groves have been planted to varieties suited to olive oil production. Approximately 4% of trees are table varieties, most of which have been planted amongst groves of predominantly oil or dual-purpose varieties.

Comparison Of Optical Density, Total Cell Protein, And Number Of Viable Cells (Via Fluorescent Straining) As Measures Of Microbial Growth Kinetics In Suspended And Biofilm Cultures During Biodegradation Of Naphthalene, Jeong Seop Shim

Dissertations

Most studies on bacterial growth kinetics have been dependent on theoretical modeling with general biomass measurements using either dry weight or optical density (OD), without distinguishing live from dead bacteria or debris. As a result, there remains considerable uncertainty in reliably predicting rates of biodegradation for design of treatment processes for environmental pollutants.

This research focused on measurement of bacterial growth rates and activities in suspended cultures and biofilms using Pseudomonas putida (ATCC 17484) for biodegradation of naphthalene. As expected, the rates of biodegradation differed between suspended and immobilized cultures. A comparison was made of the impact of three biomass …

An Examination Of Discourse Concerned With Pcb Remediation In The Hudson River, Jennifer M. Coffey

Theses

Remediation of PCB contamination in the Hudson River is an issue hotly contested within local communities, the media, and between government agencies and corporate entities. In recent years, the EPA has decided to revisit their 1984 no-action decision for the Hudson River and in December 2000, issued a Feasibility Study recommending partial dredging of the 200 miles of the Hudson floor deemed a Superfund site. The EPA's reevaluation of their 1984 decision has spurred an enormous amount of literature from corporate, non-profit volunteer, and government agencies.

The rhetorical theory of social constructionism and the ethical theory of environmental pragmatism are …

Monitoring Changes In Feral Swine Abundance And Spatial Distribution, Richard M. Engeman, Bernice Constantin, Mark Nelson, John Woolard, Jean Bourassa

United States Department of Agriculture Wildlife Services: Staff Publications

Swine (Sus scrofa) have been introduced in many places throughout the world, and in many places they adversely affect the environment, economically impact agriculture, and/or harbor diseases transmittable to domestic livestock or humans. An easily applied method to assess their abundance is an important need for their management. To monitor efficacy of a swine control program in Florida, data from passive tracking plots provide an index of feral swine abundance. The same track data coupled with plot locations to numerically describe the spatial pattern of swine activity gave an index of pervasiveness, and a simple rate of interception …

United States Department of Agriculture Wildlife Services: Staff Publications

Bird strikes to aircraft are a globally pervasive safety and economic concern. In particular, the Anchorage, Alaska area holds substantial risk for destructive collisions between birds and aircraft. An international airport, a municipal airport, a seaplane base, and a U.S. Air Force base are situated throughout the area. Anchorage also has a burgeoning population of Canada geese (Branta canadensis parvipes), one of the species identified as posing the greatest airstrike hazards. A variety of methods are applied and a variety of research has been conducted to reduce the potential for airstrikes with geese around Anchorage.We review the nature …

Understanding Vole Problems In Direct Seeding — Strategies For Management, Gary W. Witmer, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Crop fields can provide habitat to a variety of wildlife and crop damage can result (Wywialowski 1996, 1998; Conover 1998). Among the vertebrates, damage can occur from numerous species of birds and mammals. Worldwide concern, however, has focused on rodents and a large number of species cause substantial agricultural losses each year (Witmer et al. 1995). After the advent of effective herbicides and "clean farming" practices in North America, however, many rodent problems became insignificant (Hines and Hygnstrom 2000). This is, in large part, because the fields were plowed each year, disrupting burrows and removing ground cover. The fields often …

Habitat Characteristics Around Fall Blackbird Roosts, Mark W. Lutman, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

In the fall, blackbirds form large flocks and roost overnight in cattail marshes. These blackbirds cause millions of dollars in damage to ripening sunflower fields in North Dakota, South Dakota, and Minnesota. By knowing the habitat characteristics around fall blackbird roosts sites, management officials may be able to predict future roost locations and then implement control techniques to help reduce blackbird damage to sunflower fields. We present data on the available habitat around blackbird roosts to determine if there is a relationship between the habitat and fall roost sites.

Local Removal Of Red-Winged Blackbirds: Potential For Blackbird Management?, Richard . S. Sawin, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Fall flocks of red-winged blackbirds (Agelaius phoeniceus) are well known for their ability to damage crops such as sunflower (Linz and Hanzel 1997). In response, wildlife managers have considered local population reduction as a strategy for reducing blackbird damage. Male red-winged blackbirds are logistically easier to remove than females because of their conspicuous behavior. However, they exhibit a polygynous breeding system, and male removals may be ineffective if a large population of floaters exists to replace removed birds. We present data from an experimental removal project in two North Dakota townships and discuss the implications for local blackbird …

Avian Use Of Ripening Sunflower Fields, Dionn Schaaf, George M. Linz, William J. Bleier, H. Jeffrey Homan

United States Department of Agriculture Wildlife Services: Staff Publications

In the United States, more than 90% of cultivated sunflower is raised in the northern Great Plains. Cattail marshes in this area provide nesting and roosting sites for red-winged blackbirds, yellow-headed blackbirds, and common grackles. North Dakota's breeding blackbird population was estimated at more than 2.3 million pairs in 1990. Sunflower has become an important part of blackbirds' diet from July-October . In 1999 and 2000, research was conducted on the use of avicide-treated (DRC- 1339, 3-chloro-p-toluidine hydrochloride) rice baits for managing blackbird damage in problem areas. DRC- 1339 was chosen for this purpose because of its high …

Coyote Responses To Changing Jackrabbit Abundance Affect Sheep Predation, L. Charles Stoddart, Richard E. Griffiths, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

Domestic sheep ranchers generally perceive abundances of natural prey and coyotes (Canis latrans) as important factors affecting coyote predation rates on sheep. To determine the effect of a changing natural prey base on coyote predation rates, we estimated coyote density and predation rates on ewes and lambs during part of 1 cycle of black-tailed jackrabbit (Lepus californicus) abundance on a 2,300 km² area of the Idaho National Engineering Laboratory in south-central Idaho from 1979–1985. We used 100, 1.6-km scat collection lines and 80, 1.6-km flushing transects to assess coyote and jackrabbit densities, respectively. Ewe and …

Land Use Patterns In Relation To Lake Water Quality In The Lake George And Oaks Pond Watersheds, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

There has always been an inexplicable wonder associated with the beauty of Maine lakes. In addition to their aesthetic value, lakes and ponds provide important habitats for aquatic and terrestrial wildlife. The attraction of the lake's natural beauty, however, can increase recreational pressures that may lead to human induced eutrophication. Lake George and Oaks Pond were chosen as the Colby Environmental Assessment Team's (CEAT) study sites due to the concern about potential human induced eutrophication of both water bodies. Lake George and Oaks Pond are situated in southern Somerset County, Maine, and experience heavy recreational and developmental uses. Neither water …

Bollgard Cotton: An Assessment Of Global Economic, Environmental, And Social Benefits, Julie M. Edge, John H. Benedict, John P. Carroll, H. Keith Reding

School of Natural Resources: Faculty Publications

Insect-protected crops like Bollgard (Monsanto Company, St. Louis) Bacillus thuringiensis (Bt) cotton are bringing cotton growers new alternatives to broad-spectrum insecticide use in integrated pest management. After five years (1996-2000) of commercial use, a number of benefits of Bt cotton technology to growers, the environment, and society at large have been reported; however, the benefits of the technology have not been examined to date from a holistic point of view. Accordingly, the objectives of this paper were to examine the potential economic, environmental, and social benefits of Bt cotton compared with broad-spectrum insecticide use, as reported in current literature, …
