Susceptibility Of Adult Colorado Potato Beetle (Leptinotarsa Decemlineata) To The Fungal Entomopathogen Beauveria Bassiana, Ellen Klinger
Electronic Theses and Dissertations
Factors influencing the susceptibility of adult Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), to the fungal entomopathogen, Beauveria bassiana (Bals.), were studied. In an assay comparing trials between a): laboratory reared, non-diapausing beetles and b): field collected, post-diapausing beetles, survival of B. bassiana treated beetles was higher for non-diapausing adults, however, control mortality was higher for post-diapausing adults. In a similar assay with field collected pre- and post-diapausing beetles, survival of B. bassiana treated individuals was higher for post-diapause adults and control mortality was higher for post-diapausing adults than pre-diapausing beetles. In a third experiment, the effect of time from …
An Engineering, Economic, And Political Approach To Beach Erosion Mitigation And Harbor Development: A Review Of The Beach Communities Of Camp Ellis, Maine, Wells, Maine, And Cape May, New Jersey, Edmund Cervone
Electronic Theses and Dissertations
The history of coastal engineering projects is fraught with problems. In this thesis I examine the federal navigation project at Wells, Maine. In Wells, an incomplete understanding of the coastal setting led to a faulty engineering design responsible for a poorly functioning inlet and harbor and damage to neighboring beaches and wildlife habitat. Project planners and designers did not account for all unforeseen problems that arose. Reviewing the history of Wells Harbor demonstrates how proper attention to the natural setting, economics, and the political environment is essential to a successful project and enables agencies and stakeholders better to address contingencies …

Emotion Management In Children With Anxiety Disorders: A Focus On The Role Of Emotion-Related Socialization Processes, Cynthia M. Suveg
Electronic Theses and Dissertations
This study examined emotion management skills in anxious children and their mothers and investigated factors within the child and the parent, and the child-parent relationship that may relate to the development of adaptive emotion management. Three methods of emotion socialization were examined: parental reactions to children's emotions, discussion of emotion, and family expressivity. Children ages 8-1 1 years old were first screened for anxious syrnptomatology in their classrooms within the public school system. Children who scored in the clinical range on the self-report measure were then administered a semi-structured diagnostic interview. Those who met criteria for an anxiety disorder were …
Language In Social Contexts: An Examination Of The Effects Of The Linguistic Intergroup Bias On Social Categorization And Interpersonal Behavior, Virginia Ann Cylke
Language In Social Contexts: An Examination Of The Effects Of The Linguistic Intergroup Bias On Social Categorization And Interpersonal Behavior, Virginia Ann Cylke
Electronic Theses and Dissertations
This dissertation examines the role of language in social contexts. Specifically, two experiments were designed to extend our understanding of the Linguistic Intergroup Bias (LIB) by elucidating its effects on stereotype application and social behavior. The LIB is the tendency to describe positive in-group and negative out-group behaviors more abstractly than negative in-group and positive out-group behaviors. The first experiment examined the extent to which the LIB augments intergroup categories and perpetuates stereotype use. When asked to match positive and negative behavioral descriptions written at different levels of abstraction to in-group and out-group faces, participants tended to categorize abstract negative …

This study examined the psychological correlates of asymmetric cerebral activation as measured by electroencephalograph (EEG) recordings. Five content areas were investigated in the context of EEG asymmetry: hierarchical visual processing, creative potential, mood, personality, and EEG asymmetry, and the effect of a mood induction procedure on cognition and EEG asymmetry. Undergraduate participants completed two experimental sessions separated by two to three weeks. Participants completed a comprehensive set of emotion, personality, and creative potential measures, a cognitive task assessing individual differences in hierarchical visual processing. and a short form of the Rorschach inkblot test. Additionally. each participant underwent either a happy …
Resilience Of Green Sea Urchin (Strongylocentrotus Droebachiensis) Populations Following Fishing Mortality: Marine Protected Areas, Alternate Stable States, And Larval Ecology, John Vavrinec Iii
Electronic Theses and Dissertations
The green sea urchin Strongylocentrotus droebachiensis has been aggressively fished in Maine since 1986 resulting in severe population declines throughout portions of the state. This research used Marine Protected Areas (MPAs) to evaluate the potential for recovery in depleted sea urchin populations. It was necessary to not only look at the direct impacts of the MPAs, but also at larval transport / supply and community interactions to gain a better understanding of the system. We found that MPAs in the Gulf of ~a!ne were of varied utility to restoring depleted sea urchin populations depending on location and community structure. MPAs …
Hydroperiod Of Wetlands And Reproduction In Wood Frogs (Rana Sylvatica) And Spotted Salamanders (Ambystoma Maculatum), Mary Beth Kolozsvary
Hydroperiod Of Wetlands And Reproduction In Wood Frogs (Rana Sylvatica) And Spotted Salamanders (Ambystoma Maculatum), Mary Beth Kolozsvary
Electronic Theses and Dissertations
Many amphibians rely on wetlands for reproduction and the differential distribution of amphibian species along a gradient of wetland permanence is striking, yet not absolute. Wood frogs (Rana sylvatica) and spotted salamanders (Ambystoma maculatum) are thought to rely on seasonal wetlands for greatest breeding success, but there is little documentation of their reliance on these or other habitats. In my first chapter, I studied these species in wetlands across a hydrologic gradient from seasonal wetlands of short flood duration to permanently flooded sites. My results indicate that wood frogs have greatest reproductive effort and success in …

Students with bachelor and advanced degrees are thought to be an asset to the community and the state since they add to the …
Public Commons For Geospatial Data: A Conceptual Model, Chakravarthy Namindi Sharad
Public Commons For Geospatial Data: A Conceptual Model, Chakravarthy Namindi Sharad
Electronic Theses and Dissertations
A wide variety of spatial data collection efforts are ongoing throughout local, state and federal agencies, private firms and non-profit organizations. Each effort is established for a different purpose but organizations and individuals often collect and maintain the same or similar information. The United States federal government has undertaken many initiatives such as the National Spatial Data Infrastructure, the National Map and Geospatial One-Stop to reduce duplicative spatial data collection and promote the coordinated use, sharing, and dissemination of spatial data nationwide. A key premise in most of these initiatives is that no national government will be able to gather …
Spatial Aspects Of Metaphors For Information: Implications For Polycentric System Design, Paul Charles Schroeder
Spatial Aspects Of Metaphors For Information: Implications For Polycentric System Design, Paul Charles Schroeder
Electronic Theses and Dissertations
This dissertation presents three innovations that suggest an alternative approach to structuring information systems: a multidimensional heuristic workspace, a resonance metaphor for information, and a question-centered approach to structuring information relations. Motivated by the need for space to establish a question-centered learning environment, a heuristic workspace has been designed. Both the question-centered approach to information system design and the workspace have been conceived with the resonance metaphor in mind. This research stemmed from a set of questions aimed at learning how spatial concepts and related factors including geography may play a role in information sharing and public information access. In …
The Characteristics That Control The Stability Of Eroding Coastal Bluffs In Maine, Corinn C. Keblinsky
The Characteristics That Control The Stability Of Eroding Coastal Bluffs In Maine, Corinn C. Keblinsky
Electronic Theses and Dissertations
Bluffs of glacigenic sediment exist along 53% of the tidal shoreline of Maine. Under the current regime of rising sea level, waves, groundwater, and sub-aerial processes easily erode these materials. The hazardous nature of the bluffs is not widely recognized by the public, and new homeowners are often shocked to find out that their property is disappearing. To better educate the public, the Maine Geological Survey is mapping the stability of coastal bluffs. This report utilizes that database along with other available data to determine what controls the relative stability of bluffs. A geographic information system (GIs) was used to …
Testing Two Food Frequency Questionnaires And Stage-Based Newsletters With Economically Disadvantaged Young Adults, Beth J. Williams
Testing Two Food Frequency Questionnaires And Stage-Based Newsletters With Economically Disadvantaged Young Adults, Beth J. Williams
Electronic Theses and Dissertations
One of the most important ways to decrease risk of chronic disease development is to consume ample portions of h i t and vegetables. However, less than one-third of young adults meet "5-A-Day" servings, and variety is limited. Economically disadvantaged young adults may be especially vulnerable and are a hard to reach audience. Many of the Cooperative Extension programs are designed to reach low-income audiences and assist them in making changes in knowledge, skills, attitudes, and dietary choices for nutritional well-being. The objectives of this study were, in Phase I, to test two food frequency instruments for feasibility of use …
Reactions Of Alcohols And Organophosphonates On Tungsten Trioxide Epitaxial Films, Shuguo Ma
Reactions Of Alcohols And Organophosphonates On Tungsten Trioxide Epitaxial Films, Shuguo Ma
Electronic Theses and Dissertations
The adsorption, diffusion, reactions, and desorption of water, alcohols, ethers, and an organophosphonate were studied using calibrated thermal desorption spectroscopy (CTDS) on thin film WO3(OOl) surfaces grown epitaxially on a single crystal α- Al2O3(li02) (sapphire) substrate. The studies were conducted on oxidized and reduced surfaces, which were characterized by x-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS). The desorption spectra for molecular desorption of all of these molecules shifted to lower temperature with increasing coverage, and had overlapping tails on the high temperature side. Monte Carlo simulations show that this typical desorption shape …
Relationship Between Alkaline Pulp Yield And The Mass Fraction And Degree Of Polymerization Of Cellulose In Pulp, Mehmet Sefik Tunc
Relationship Between Alkaline Pulp Yield And The Mass Fraction And Degree Of Polymerization Of Cellulose In Pulp, Mehmet Sefik Tunc
Electronic Theses and Dissertations
Wood as a raw material is generally the dominant cost factor for the production of chemical pulp. Therefore, an increase in pulp yield has a major impact on the competitiveness of a mill. In order to optimize pulp yield, for example by changing operating conditions, a mill must be able to monitor the yield accurately. However, an accurate "real-time" pulp yield measurement method is not available at the present time. Pulping yield is presently measured from the amount of pulp produced from a given quantity of wood consumed over a 3 to 6 month time frame. This method is obviously …
Friendship Formation And Maintenance: Examining Friendship Patterns Of Homosexual Men And Heterosexual Women In Close Relationships, Amanda G. Goodwin
Friendship Formation And Maintenance: Examining Friendship Patterns Of Homosexual Men And Heterosexual Women In Close Relationships, Amanda G. Goodwin
Electronic Theses and Dissertations
The study of friendship has focused on various types of relationships involving same-sex and cross-sex friends. Heterosexuality has usually been assumed in these relationships, although recently research has been done involving homosexual friendships. The present study provides a quantitative analysis of personal-social characteristics and relational expectations, and a qualitative analysis of friendship formation, maintenance strategies, and relational importance of homosexual men and heterosexual women in close relationships with each other. These analyses help in understanding why and how close friendships between homosexual men and heterosexual women are formed and maintained. A questionnaire combining elements of one developed by Savin-Williams (1990) …
Effects Of Precommercial Thinning On Snowshoe Hares, Small Mammals, And Forest Structure In Northern Maine, Jessica A. Homyack
Effects Of Precommercial Thinning On Snowshoe Hares, Small Mammals, And Forest Structure In Northern Maine, Jessica A. Homyack
Electronic Theses and Dissertations
The extent of precommercial thinning (PCT) to manipulate stand density in overstocked, regenerating stands and to accelerate growth, yield, and the rate of development of crop trees has been increasing within the Acadian forest of northeastern North America. Although the silvicultural responses of crop trees to thinning are well studied, few studies have evaluated the effects of PCT on forest-dependent wildlife and their habitat. I investigated the effects of PCT and stand succession on snowshoe hares, small mammals, and forest structure on 38 stands (25 treated with PCT, 13 unthinned stands) from 1 to 16 years post-treatment within 7 townships …
Modeling Bird Species Occurrence In Current And Future Landscapes, Stephen Nicholas Matthews
Modeling Bird Species Occurrence In Current And Future Landscapes, Stephen Nicholas Matthews
Electronic Theses and Dissertations
With mounting evidence that global temperatures have increased significantly over the last century and the projections of greater changes in climate by the end of this century, understanding the potential consequences of these changes for species is essential to conservation efforts. Here I evaluate the potential response of birds to projected climate change by using regression tree analysis to create models of species distributions under current conditions from Breeding Bird Survey data and then project these models onto General Circulation Model (GCM) scenarios of global climate change. Before modeling species responses to climate change, I selected seventeen bird species to …
The Effects Of Stress Induction On Pre-Attentive And Attentional Bias For Threat In Social Anxiety, Kristen M. Maki
The Effects Of Stress Induction On Pre-Attentive And Attentional Bias For Threat In Social Anxiety, Kristen M. Maki
Electronic Theses and Dissertations
The current investigation is a test of the vigilance-avoidance model of attentional processing in a socially anxious sample (Mogg, Bradley, de Bono, & Painter, 1997). The theory proposes that individuals with social phobia possess a pre-attentive bias for social threat cues in their environment, however, they subsequently fail to process this information due to strategic cognitive avoidance, that is, conscious efforts to disengage attention from threatening information. A combined subliminal/supraliminal emotional Stroop paradigm was employed in order to examine patterns of pre-attentive and attentional processing of threat cues in an analogue sample of undergraduate students with high versus low levels …
The Use Of Acoustics To Resolve Nightly Excursions Of Hyperbenthos, Heather U. Abello
The Use Of Acoustics To Resolve Nightly Excursions Of Hyperbenthos, Heather U. Abello
Electronic Theses and Dissertations
Acoustic analysis of die1 vertical migration in the Darnariscotta River estuary, Maine, showed a fairly regular nightly increase in biovolume (mm3 m'3) of organisms in the water column, presumed to be due to emergence, the entry of hyperbenthic organisms into the water column. Timing of these events was significantly correlated with time of sunset and time of sunrise for more than 50% of the dates where emergence and re-entry could be identified, between June and October 2002. Emergence traps indicate that the mysid shrimp, Neomysis americana, is the predominant migrator. Daily fluctuations in irradiance influence the timing of emergence fiom …
Jacques Poulin Et Le Nouveau Roman De Tendre: (Jacques Poulin And The New Tender Novel), Cynthia Currie Lees
Jacques Poulin Et Le Nouveau Roman De Tendre: (Jacques Poulin And The New Tender Novel), Cynthia Currie Lees
Electronic Theses and Dissertations
The main objective of this thesis is to demonstrate the fundamental importance of the Carte de Tendre of Mlle de Scudéry in the works of Jacques Poulin. Distinct from previous studies, this analysis is based on the premise that Poulin has made a unique contribution to Quebec literature with his novel of tenderness which recalls the celebrated map in Clélie, Histoire Romaine. Where Scudéry envisages land, air and sea routes to Tendre, Poulin likewise evokes the themes of travel and tenderness. These two themes are intertwined since travel, for the poulinian hero, serves as a pretext for rediscovering his …
La Signification Et L'Influence Des Cinq Sens Sur Le Suet De La Domestication Dans L'Oeuvre De Colette [The Signification And Influences Of The Five Senses On The Topic Of Domestication In The Work Of Colette], Ann Robbins
Electronic Theses and Dissertations
Colette stands alone in her time as a woman who brought a new way of looking at the world. Critics have accused her of frivolity because she stressed the senses and not the intellect as a means of interacting with life, but in her demonstration of style and thought she worked her intellect beyond conventional boundaries, creating a new liberal humanitarianism that recently has seen a resurgence in popularity. One can find quotes from Colette's work in popular magazines and advertisements, proving the timelessness of her influence. When Colette was writing she used experiences from her childhood in the French …

Effects Of Small-Gap Timber Harvests On Songbird Community Composition And Site-Fidelity, Mitschka John Hartley
Effects Of Small-Gap Timber Harvests On Songbird Community Composition And Site-Fidelity, Mitschka John Hartley
Electronic Theses and Dissertations
I investigated effects of small-gap timber harvests on bird communities at nine sites (10 ha each) within the Penobscot Experimental Forest (PEF), grouped into three replicated "blocks" (three sites each). Blocks were randomly treated with three treatments: 10% harvest, 20% harvest, and no harvest (i.e., control). I examined how treatments affected breeding songbird abundance, richness, and site-fidelity over four consecutive summers, including 1-3 years before and after each site was harvested. Ability to detect treatment effects was limited by the small number of replicates, but power analyses indicated that given the experimental design and observed variability, there was a high …
Scope For Activity, Specific Dynamic Action And Growth In Early Juvenile Stages Of Atlantic Cod, Gadus Morhua, Sorren Lund Hansen
Scope For Activity, Specific Dynamic Action And Growth In Early Juvenile Stages Of Atlantic Cod, Gadus Morhua, Sorren Lund Hansen
Electronic Theses and Dissertations
Growth rates of early life stages of Atlantic cod (Gadus morhua) are very high, but decline, as the fish grow larger. Little is know about the physiological processes that facilitate and regulate this growth pattern. In this study, feeding and swimming metabolism were measured in individual juvenile Atlantic cod (Gadus morhua) in order to investigate how energy are allocated to swimming and growth in fast growing stages of fishes. Metabolic rates were measured by the means of oxygen consumption using two "Brett-type" respirometers. The metabolic measurements were repeated several times in individual juvenile Atlantic cod with a wet body mass …

Surface Interactions Of Mercury On Gold Foil Electrodes In Electrodeposition And Stripping And ; An Investigation Of Free Thiolate Ions From Metal-Thiolate Chalcogenides, Charles Martin Watson
Electronic Theses and Dissertations
Mercury, a highly toxic metal, whose environmental concentration magnifies with ascension of the food chain, is monitored in our waters, food and air. Monitoring mercury is generally done by sample collection, transport to the laboratory; followed by: digestion of the sample, separation of the mercury and detection of the mercury: mostly by cold vapor atomic absorption or, cold vapor atomic fluorescence. These monitoring methods, preclude, routine, in-the-field mercury determination. New analytical techniques have been proposed for in the field determination of mercury. They consist of mercury adsorption onto a sensor or electrode and measuring how much is there either as …

Vaccines For Infection Salmon Anemia Virus, Nathan Edward Charles Brown
Electronic Theses and Dissertations
Infectious salmon anemia (ISA) virus is an emerging pathogen of fanned Atlantic salmon. Due to the massive economic losses inflicted by the ISA virus, effective measures to control future outbreaks are necessary. An attractive method for preventing ISA virus from infecting stocks of Atlantic salmon is vaccination. DNA vaccination is a proven cheap, effective means of protecting fish from aquatic viruses. In this thesis DNA vaccination of Atlantic salmon was investigated. Three different strains of ISA virus were cultured and purified by density gradient ultracentrifugation. ISA virus RNA was isolated and used to amplify full-length cDNAs of five ISA virus …
