Evaluation Of Terrestrial Carbon Cycle Models Through Simulations Of The Seasonal Cycle Of Atmospheric Co2: First Results Of A Model Intercomparison Study, Martin Heimann, Gerd Esser, A. Haxeltine, Jorg Kaduk, W. Knorr, Gundolf H. Kohlmaier, A. David Mcguire, Jerry M. Melillo, Berrien Moore Iii, R. D. Otto, I. Colin Prentice, Walter Sauf, Annette L. Schloss, Stephen Sitch, Uwe Wittenberg, G. Wurth

All Materials

Results of an intercomparison among terrestrial biogeochemical models (TBMs) are reported, in which one diagnostic and five prognostic models have been run with the same long-term climate forcing. Monthly fields of net ecosystem production (NEP), which is the difference between net primary production (NPP) and heterotrophic respiration RH, at 0.5° resolution have been generated for the terrestrial biosphere. The monthly estimates of NEP in conjunction with seasonal CO2 flux fields generated by the seasonal Hamburg Model of the Oceanic Carbon Cycle (HAMOCC3) and fossil fuel source fields were subsequently coupled to the three-dimensional atmospheric tracer transport model TM2 forced by …

Relationship Between Ecosystem Productivity And Photosynthetically-Active Radiation For Northern Peatlands, Steve Frolking, Jill L. Bubier, Tim R. Moore, T Ball, L M. Bellisario, A Bhardwaj, P Carroll, P Crill, P M. Lafleur, Harry Mccaughey, Nigel T. Roulet, Andrew E. Suyker, J M. Whittington, G J. Whiting

Earth Sciences

We analyzed the relationship between net ecosystem exchange of carbon dioxide (NEE) and irradiance (as photosynthetic photon flux density or PPFD), using published and unpublished data that have been collected during midgrowing season for carbon balance studies at seven peatlands in North America and Europe. NEE measurements included both eddy-correlation tower and clear, static chamber methods, which gave very similar results. Data were analyzed by site, as aggregated data sets by peatland type (bog, poor fen, rich fen, and all fens) and as a single aggregated data set for all peatlands. In all cases, a fit with a rectangular hyperbola …

In The Title Ix Race Toward Gender Equity, The Black Female Athlete Is Left To Finish Last: The Lack Of Access For The “Invisible Woman", Tonya M. Evans

Law Faculty Scholarship

Although each of us is defined by race and gender, those of us who are neither white nor male often experience invisibility as a result of our dual subordinate status.... Black women have been disproportionately located at the lower end of the economic hierarchy and, therefore, have been unable to afford private golf, swimming, or tennis lessons. Overt racial discrimination prevented black women from gaining access to the sports participated in by white women. To the extent that the main thrust of solutions to gender inequity and a lack of adherence to Title IX mandates has been the addition of …

Reproductive Ecology Of Canada Mayflower (Maianthemum Canadense Desf), Michael Todd Ganger

Doctoral Dissertations

Canada mayflower (Maianthemum canadense var. canadense Desf.), a rhizomatous perennial herb, was the subject of field experiments investigating the role of several factors on the sexual reproduction of ramets. Mayflower ramets may be either flowering (with 2-3 leaves and a terminal inflorescence consisting of 4-35 perfect flowers) or vegetative (1 leaf).

Pollen addition increased the number of seeds matured by ramets in three out of four years in which pollen level was experimentally manipulated. The lack of compatible pollen is thought to be a major factor limiting seed maturation by ramets.

The act of severing the rhizomes, such that ramets …

Alternative Removal Methodologies For Environmental Waters, Shannon Patrick Hogan

Doctoral Dissertations

The Environmental Protection Agency (EPA) continues to establish criteria for the reduction of pathogens in environmental waters used for drinking water. The EPA also states criteria on the amount of chlorine by-products allowed in drinking water. Alternative removal methods that are used in conjunction with chlorine are needed to assure safe drinking water.

The Surface Water Treatment Rule (SWTR) states that a 99.99% reduction of viruses and a 99.9% reduction in Giardia lamblia cysts needs to be achieved by a treatment facility that uses surface water for the production of drinking water. The SWTR also states Maximum Contaminant Levels (MCL) …

Population Structure And Phylogenetic History Of The Lake Malawi Cichlid Species Flock, Jeffrey Alan Markert

Doctoral Dissertations

The cichlid species "flocks" which are endemic to the East African Rift Valley are characterized by frequent lineage splitting events which have led to the rapid evolution of high levels of taxonomic diversity. Changes in water level cause these habitat patches to be chronically unstable, hypothetically speeding the process of genetic differentiation through the combined effects of genetic drift and selection. Allele frequencies at four simple sequence repeat loci indicate low levels of gene flow in two rock dwelling fish species, Melanochromis auratus and Labeotropheus fuelleborni, collected from the Nankumba Peninsula in southern Lake Malawi. Small interruptions in habitat cause …

"The Tawnee Family": The Life Course Of Indian Value Adaptation For Eleazar Wheelock's Indian Scholars, Stacy Lynn S Hogsett

Doctoral Dissertations

This dissertation is a study of value adaptation by the southern New England Indians who attended Moor's Charity School, in Lebanon, Connecticut, between 1743 and 1770. These Indians were part of New Light Minister Eleazar Wheelock's extended household, dubbed by one student, the "tawnee family." This designation distinguished these Indian scholars as surrogate members of the Wheelock family. I analyzed how the Indian students adapted to, resisted and reformed the values taught at Moor's as they grew to adulthood.

I drew my analysis from letters collected in the Eleazar Wheelock Papers housed at Dartmouth College. My arguments are drawn principally …

Influences On Teachers' Curricular Choices In Project-Based Science Classrooms, Karen Anne Laba

Doctoral Dissertations

This descriptive research will present two case studies of experienced science teachers using project-based curricula in all or part of their secondary life science/biology courses. The purpose of this study is to reveal the underlying relationships between teachers' conceptions of the nature of science, their understanding of their role as science teachers and their expectations for appropriate and worthwhile student learning, and to describe the influence of these factors on their curricular choices within the project-based framework. Using a modification of Hewson, Kerby and Cook's (1995) Conceptions of Teaching Science protocol as a model, teachers' beliefs and intentions are classified …

Factors That Influence The Decision Regarding Hormone Replacement Therapy In Postmenopausal Women, Ruth A Rogers Reilly

Doctoral Dissertations

Cardiovascular disease is the leading cause of death in women in the United States today. Prior to menopause women have lower rates of heart disease than men; however, after menopause a woman's risk for heart disease rises dramatically. This is thought to be due the ovaries' decreased production of estradiol, but the mechanisms for this effect have not been fully elucidated. The need exists to investigate the impact of healthy lifestyles on attenuating the risk of cardiovascular disease in women as they age.

The majority of research on hormone replacement therapy (HRT) has focused on the biomedical model suggesting that …

Reconceptualizing Early Childhood Preservice Teacher Education: A Pedagogy Of Collaborative Inquiry, Mary Jane Moran

Doctoral Dissertations

This study describes changes in thinking and practice among 24 early childhood preservice teachers as they move away from a reliance on traditional interpretations of child-centered curricula and developmentally appropriate practices toward one of collaborative inquiry. Participants enrolled in a 15 week undergraduate teaching methods course were assigned to teaching teams to implement collaborative projects with the same group of three to five year-old children.

Traditionally, early childhood teacher education has been influenced by developmental theory which emphasizes processes of children's learning. And yet, teachers typically learn to teach from a transmission orientation with perspectives provided by experts rather than …

Bioavailability Of Nutrients And Metals Following Land Application Of Organic Wastes, Jianqiang Zhao

Doctoral Dissertations

Field, greenhouse and laboratory studies were conducted to investigate the effects of soil-incorporated organic wastes on nitrogen release patterns, groundwater nitrate-nitrogen levels, nutrient/metal uptake, and plant yield.

Three field studies with corn (Zea mays L.) were conducted during 1993 to 1997 at three locations in New Hampshire using a randomized complete block design with three or four replications, two or three waste materials as main plots, and various application rates as subplots. Compared to dairy manure, Concord biosolids showed a slower release rate measured as soil NO$\sb3$-N concentrations in early season but higher post-harvest levels of soil NO$\sb3$-N.

Groundwater NO$\sb3$-N …

Issues Of Engendered Entitlement: Who Owns The Classroom? Who Owns Knowledge?, Dorothy Radius Kasik

Doctoral Dissertations

This dissertation examines the ways in which first year female college students have been prepared by educational systems in our culture to handle knowledge and the acquisition of knowledge during the first year of college experience. It is the contention of the author that women are not actively encouraged in our culture to take ownership of educational concepts in the same way as men. This happens for two reasons, first that because women's methods of interaction in the classroom might differ from men's those methods might not be perceived as acceptable or taken seriously; and second that a woman's discomfort …

Examining Student Conceptions Of The Nature Of Science From Two Project-Based Classrooms, David M. Moss

Doctoral Dissertations

The purpose of this research was to develop descriptive accounts of precollege students' conceptions of the nature of science from two project-based classrooms, and track those conceptions over the course of an academic year. A model of the nature of science was developed and served as the criterion by which students' beliefs were evaluated. The model distinguishes between two major categories of science, the nature of the scientific enterprise and the nature of scientific knowledge. Five students were selected from each class and interviewed individually for 30-45 minutes each, six times over the year. Data from semi-structured, formal interviewing consisted …

Dynamics Of Dissolved Organic Carbon During Weathering And Soil Formation, Kimberly Linnea Mccracken

Doctoral Dissertations

Interactions between dissolved organic carbon (DOC) and mineral soils were examined in field and laboratory experiments. Specific emphasis was given to factors influencing DOC mobility and element release during mineral weathering and soil formation. Soil chemical and physical properties controlling equilibrium concentrations of DOC (DOC$\rm\sb{np})$ in coarse-textured forest soils were investigated using laboratory batch reactors and the initial mass isotherm approach. The influence of DOC concentration on release of metals and silica was investigated in four soil parent materials. One of four acid treatments (0.001 N HNO$\sb3$ and three concentrations of forest floor leachate) or distilled water were added to …

Measuring And Modeling Northeastern Forest Ecosystem Response To Environmental Stresses, Jennifer Caroline Jenkins

Doctoral Dissertations

Because forest responses to CO$\sb2$ fertilization and associated climate change are likely to be extremely complex, numerical models representing forest response to an integrated set of future conditions can be useful predictive tools. I compared predictions of forest net primary productivity (NPP) made by two ecosystem process models (PnET-II and TEM 4.0) using different climate scenarios, spatial resolutions, and methods of representing land cover and soils. Decreasing spatial resolution did not appreciably change NPP estimates. Input datasets, particularly climate, land cover, and soil water holding capacity, were important sources of variability in NPP estimates. These datasets interacted with model structures …

Attachment Of Listeria Monocytogenes To Murine And Human Phagocytic Cells, Srinivas Maganti

Doctoral Dissertations

Listeria monocytogenes is a facultative intracellular pathogen responsible for meningoencephalitis, septicemia, and abortion in susceptible and immunocompromised individuals. Subsequent to colonization and penetration of the gut epithelium, the organism attaches to resident macrophages and replicates intracellularly, thus evading the humoral immune system of the infected host. The mechanism surrounding the precise interactions between L. monocytogenes and macrophages employs bacterial ligands and macrophage receptors which are highly complex and not well understood. The focus of the present study was to investigate the attachment of the organism to murine and human macrophages under opsonin-dependent and opsonin-independent conditions to better understand the pathobiology …

Non-Major Histocompatibility (B) Complex Effects On Rous Sarcomas And V-Src-Induced Tumors, Keith Thomas Lepage

Doctoral Dissertations

Rous sarcoma virus and v-src-induced tumor outcome is controlled by the major histocompatibility (B) complex. While data have suggested non-MHC effects, few studies have focused on systems other than the B complex. Experiment one matings produced $B\sp2B\sp5$ and $B\sp5B\sp5$ progeny which segregated for alleles of 7 additional blood groups (A, C, D, H, I, L, P) and the Rfp-Y system. Experiment one survivors produced Experiment two progeny. The $B\sp5B\sp5$ parents for Experiment three combined different background genes with a tumor progressor B haplotype using the F$\sb2$ generation of a cross between Line SC ($B\sp2B\sp2$) and Line 6.15-5 ($B\sp5B\sp5$).

Controls On Ch(4) Emissions From Boreal And Arctic Wetlands, Sadredin Cyrus Moosavi

Doctoral Dissertations

This thesis examines the environmental controls on the biogeochemical cycling of the radiatively active trace gas CH$\sb4$ within boreal and arctic wetlands. Net CH$\sb4$ flux along peatland hydrologic gradients were examined to determine the effects of temperature and water table on CH$\sb4$ emissions. The level of the water table acts as a switch between CH$\sb4$ production and oxidation with small water level changes producing large changes in flux balance. Soil temperature determined whether CH$\sb4$ production potential was realized within sufficiently moist environments. A selective inhibitor technique was developed for directly measuring CH$\sb4$ oxidation in wetland soils. CH$\sb4$ oxidation was found …
