Institutional And Individual Influences On Scientists' Data Sharing Behaviors, Youngseek Kim

School of Information Studies - Dissertations

In modern research activities, scientific data sharing is essential, especially in terms of data-intensive science and scholarly communication. Scientific communities are making ongoing endeavors to promote scientific data sharing. Currently, however, data sharing is not always well-deployed throughout diverse science and engineering disciplines. Disciplinary traditions, organizational barriers, lack of technological infrastructure, and individual perceptions often contribute to limit scientists from sharing their data. Since scientists' data sharing practices are embedded in their respective disciplinary contexts, it is necessary to examine institutional influences as well as individual motivations on scientists' data sharing behaviors. The objective of this research is to investigate …

Lessons From Patchwork Nation: A New Framework For Building Community Indicators, Stephen Borders, James Edwards, Ashley Miller

The Foundation Review

· As interest in outcomes continues to rise, community indicators have become a widely used tool to measure progress. While indicators provide a vehicle for understanding and addressing community issues from a holistic perspective, current efforts seem to suffer from both a notable absence of local-level data and end-user information overload, whereby the presentation of numerous and often disconnected indicators makes it difficult to draw meaningful conclusions from the analysis.

· We highlight the results and our experiences with a community health needs assessment conducted through an indicator project in Michigan’s Kent County. The analysis and visualization of the indicator …

Whole-Nature: Integrating Science And Eco-Phenomenology, Bartholomew Patrick Walsh

Graduate Student Theses, Dissertations, & Professional Papers

A review of the literature in environmental philosophy reveals a certain tension between what we might call science-based and experience-based approaches to environmental ethics. The main trend of thought here follows seminal figures like Aldo Leopold and Holmes Rolston III by generally looking to the sciences for disclosing value in nature, particularly ecology and evolutionary biology. However others, such as David Abram and Jack Turner, worry that scientifically disclosed nature is in itself too distancing, objectifying, and abstract to engender any real care for nature and instead emphasize direct, embodied experience with actual wild places, hence the label “eco-phenomenology.” The …

Synthesis Of Dna-Base Selective Labels For Efficient Labeling Of Dna For Tem Imaging, Rakesh Kumar

Graduate Student Theses, Dissertations, & Professional Papers

The goal of this project was to explore the possibility of high throughput DNA sequencing using high-resolution electron microscopy. This approach was recently made feasible by development of a DNA threading technique that allows the imaging of straight, single stranded DNA; and by the development of atom-by-atom analysis with Transmission Electron Microscopy (TEM). In an attempt to better understand the types of interactions that can occur between water-soluble versions of complex and DNA we have synthesized the series of single metal and tetrametallic compounds. In order to demonstrate proof of concept for the technique of visualizing metal complex bound on …

Extrahepatic 25-Hydroxylation Of Vitamin D3 In An Engineered Osteoblast Precursor Cell Line Exploring The Influence On Cellular Proliferation And Matrix Maturation During Bone Development, Shelley S. Mason, Sean S. Kohles, Shelley R. Winn, Randy D. Zelick

Biology Faculty Publications and Presentations

Osteoblastic precursors experience distinct stages during differentiation and bone development, which include proliferation, extracellular matrix (ECM) maturation, and ECM mineralization. It is well known that vitamin D plays a large role in the regulation of bone mineralization and homeostasis via the endocrine system. The activation of vitamin D requires two sequential hydroxylation steps, first in the kidney and then in the liver, in order to carry out its role in calcium homeostasis. Recent research has demonstrated that human-derived mesenchymal stem cells (MSCs) and osteoblasts can metabolize the immediate vitamin D precursor 25- dihydroxyvitamin D₃(25OH₂D₃) to the active steroid 1α,25-dihydroxyvitamin D₃ …

Osmb Ais Funds Final Report: Task 1 Boat Ramp Monitoring For New Zealand Mud Snails, Valance Brenneis, Samuel Cimino, Angela L. Strecker

Center for Lakes and Reservoirs Publications and Presentations

The New Zealand mud snail (Potamopyrgus antipodarum; NZMS) is an invasive species found in a variety of ecosystems in Oregon, including brackish estuaries, heavily used recreational rivers, and highly trafficked coastal freshwater lakes. NZMS are an invasive species of concern because once established, they may out-compete native invertebrate grazers, such as native insect larvae that provide important food resources for fish, and NZMS themselves provide little nutritional value. Monitoring for the presence and population density of NZMS was performed at boat ramps located along several water bodies in 2006 – 2007. These water bodies were then re-sampled during the summer …

Effects Of Disturbance On Tree Community Dynamics In Whitebark Pine Ecosystems, Jeremy Travis Amberson

Graduate Student Theses, Dissertations, & Professional Papers

Whitebark pine (Pinus albicaulis), a keystone species of high-elevation ecosystems of western North America, is warranted for listing under the Endangered Species Act due to the combined threats of fire exclusion, white pine blister rust (Cronartium ribicola), and increased pressure from insects due to climate warming. Despite widespread knowledge of the potential causes of the tree’s decline, there is limited understanding of its ecology, including successional dynamics in forests disturbed by white pine blister rust and mountain pine beetle. Specifically, there is a need for more information on successional replacement by subalpine fir and whitebark seedling regeneration dynamics. I assessed …

Air Circulation Under Reduced Atmospheric Pressures, Lendell E. Hillhouse

Theses and Dissertations

The control of heat exchange is vital for plant life in off-world, low pressure,

greenhouses. The ability to control this process was limited by methodology and

technology. Mathematical models, based on classical mechanics are created to enhance

our control capabilities. Data is collected using various sensors placed inside the Low

Pressure Test Bed (LPTB) Chamber at Kennedy Space Center. Data from those sensors

became non-linear at various pressures below 25 kPa. We introduced mathematical

calibration corrections and found that sensor data linearity could be extended to a greater

range of pressures. These calibration corrections allow for sensor calibration corrections

Women's Use Of Intimate Partner Violence: An Examination Of Attachment, Coping, And Gender Ideology, Theresa Elizabeth Magelky

Theses and Dissertations

Until recently, much of the research on intimate partner violence has focused primarily on male aggressors. However, research has increasingly indicated that women use violence against male intimate partners at higher rates than previously suspected. Significant controversy exists with regard to the context, motivation, and types of violence used by women. The current study explored the degree to which female aggressors' attachment styles are associated with and predictive of their use of intimate partner violence against men. In addition, coping processes and feminine ideology were studied, particularly in combination with attachment style, to determine their relationship with use of partner …

An Investigation Of Gender's Role In Three- And Four-Year-Old Children's Musical Play, Kari Jo O'Keefe

Theses and Dissertations

Young children engage in many activities, with play being the most prominent. Musical play occurs when children freely investigate sound through vocal, instrumental, or other means. Identifying the extent of musical play - and the role that gender plays in musical play - may provide important information about children's natural tendencies.

The purpose of this study was to investigate gender's role in three- and four-year-old children's musical play, and to investigate further the general nature of musical play. A grounded theory methodology was used, and data was gathered from field and individual child observations, and parent and preschool teacher surveys. …

Examining The Continuity Of The Long-Lived (Triassic-Recent) Freshwater Mussel Genus Diplodon (Family Hyriidae), Matt Burton-Kelly

Theses and Dissertations

This paper addresses the question of how strong the record of contiguity is for the 250 million-year-old Diplodon lineage by examining the geographic and temporal distribution of fossil specimens identified as Diplodon.

Diplodon (Mollusca, Bivalvia, Unionoida, Hyriidae) has a fossil record extending back to the Middle Triassic (Anisian Stage). The known distribution of fossil specimens identified as this genus occurs on four continents (North America, South America, Australasia, and Antarctica). The place of origin and pathways of range expansion through time are far from well explained. Both fossil and extant freshwater mussel taxa are subject to evolutionary and phenotypic …

Sexual Fluidity And Women's Bisexual Identity Development, Julijana Draganic

Theses and Dissertations

Experiences of bisexual and sexual fluid women are poorly explored and understood in the current literature. While there is a need and interest in the exploration of bisexual experiences in the current literature, these experiences are usually lumped together with the experiences of lesbian women, who are vastly overrepresented in the participant samples. Data was collected from LGBT centers, women's centers, bisexual interest listservs, and sexual minority internet groups. This study examined: the relationship between a measure of fluidity in attractions, the Sexual Fluidity Grid (SFG) and a measure of sexual orientation, the Klein Sexual Orientation Grid; the relationship between …

Climate Change And Ragweed Allergy Risk Assessment: A Study Of The Grand Forks Metropolitan Statistical Area, Shumila Rani Ahmad

Theses and Dissertations

Nowadays the association between anthropogenic climate change and public health is in the early stages of universal recognition. Yet one fundamental aspect that remains largely unappreciated is the impact of climate change on ragweed (Ambrosia species) biology and the ensuing pathophysiology of human systems. Ragweed pollen is one of the primary causes of seasonal pollen allergy in the world. Allergic reactions to ragweed pollen can range from mild hay fever to life-threatening asthma attacks. The aim of this thesis was to conduct a ragweed allergy risk assessment for the Grand Forks ND-MN Metropolitan Statistical Area (MSA).

The study area is …

Vascular Endothelial Growth Factor In Cortical Development, Jacob Thomas Cain

Theses and Dissertations

One of the characteristics unique to mammalian evolution is the development of the neocortex. The neocortex is a highly ordered six-layered structure, the development of which is tightly regulated. The formation of the cortex is concomitantly dependent upon an outward expansion of the neuroepithelium, a tissue from which all of the neuronal subtypes and glia are born and differentiated, and the investment of blood vessels from the outer pial surface. Orchestration of neurogenesis and blood vessel investment, or angiogenesis, in the cortex is critical for development; however, these processes are often studied independent of one another. While independent investigation of …

Determination Of Optimum Polymer Dose For Grand Forks Wastewater Treatment Plant Lagoon Sludge Dewatering, Dipesh Das

Theses and Dissertations

The Grand Forks Waste Water Treatment Plant (GFWWTP) is currently sending its waste activated sludge (WAS) from the activated sludge treatment process to an existing on-site wastewater treatment lagoon which has been in operation since 2003. The plant produces approximately 65,000 gallons of WAS per day. Because of this high level of loading, the existing lagoon system is no longer considered as a treatment option for the produced sludge. The Plant Authority is trying to find a sustainable solution for sludge disposal and for this reason the GFWWTP is interested in introducing screw press system for the dewatering process. As …

Epigenetic Patterns: Process-Driven Or Sequence-Driven?, Amanda Gefroh

Theses and Dissertations

Some of the most rapidly-evolving fields of study in the medical and research communities presently are those which investigate our genetic code, the elements and factors that control the expression of our genetic code, as well as fields of study which analyze theories about an organisms' physiology and phenotype from the information that both of the previous topics concomitantly provide. The work of the Milavetz lab, among many others, is striving to fill the gaps in knowledge about epigenetic regulation of biological processes - here by using the well-suited model virus, Simian Virus 40. It has for some time now …

A Mass Spectrometry-Based Method For Quantification Of Human Metallothionein Isoforms And Usefulness In Biomarker Detection Of Cancers And Metal Toxicity, Aaron Andrew Mehus

Theses and Dissertations

Current methods for detecting metallothionein (MT) protein expression lack the specificity to distinguish between all twelve human isoforms. Each, however, can be distinguished by the masses of their acetylated, cysteine-rich, hydrophilic N-terminal tryptic peptides. These properties were exploited to develop a mass spectrometry-based method for their simultaneous quantification.

Human kidney HK-2 epithelial cells expressing recombinant MT-3 were grown in the presence or absence of cadmium. Cytosolic proteins were alkylated with 14N- or 15N-iodoacetamide and digested with trypsin. The N-terminal MT peptides were enriched by two-dimensional liquid chromatography and analyzed by MALDI-TOF/TOF mass spectrometry. Relative expression was measured by combining 14N-labeled …

The Ecology Of Host-Seeking Mosquitoes Within The Red River Valley Of Central North Dakota, Joseph Orlo Mehus

Theses and Dissertations

Host-seeking mosquitoes are taxing for people and wildlife alike in the Red River Valley (RRV). During the summer massive numbers of mosquitoes swarm the RRV, yet little is known about the ecology and biology of the mosquito species that inhabit this area. This research will help to fill some of those knowledge gaps by studying the ecology of host seeking mosquitoes in the RRV.

Host-seeking mosquitoes were collected using CO₂-baited MMX^TM traps. Trapping was conducted in two very different rural settings within the RRV. One site, a 40-acre hardwood forest with closed canopy, the other a farmstead …

Epileptic Seizure Detection And Prediction From Electroencephalogram Using Neuro-Fuzzy Algorithms, Ahmed Fazle Rabbi

Theses and Dissertations

This dissertation presents innovative approaches based on fuzzy logic in epileptic seizure detection and prediction from Electroencephalogram (EEG). The fuzzy rule-based algorithms were developed with the aim to improve quality of life of epilepsy patients by utilizing intelligent methods. An adaptive fuzzy logic system was developed to detect seizure onset in a patient specific way. Fuzzy if-then rules were developed to mimic the human reasoning and taking advantage of the combination in spatial-temporal domain. Fuzzy c-means clustering technique was utilized for optimizing the membership functions for varying patterns in the feature domain. In addition, application of the adaptive neuro-fuzzy inference …

Spirituality And Systemic Lupus Erythematosus, Kara Ann Richardson-Cline

Theses and Dissertations

Problem: The positive relationship between spirituality and physical, psychological, and social well-being has been well established. However, beyond quality of life measures, this construct has yet to be more deeply studied in a sample of individuals diagnosed with Systemic Lupus Erythematosus (SLE). Furthermore, relational spirituality has yet to be studied in a chronically ill population. Meeting these gaps in the literature, this study compared the explicit domains and latent constructs measured by a relational spirituality instrument and examined their associations with a measure of biopsychosocial-spiritual well-being and quality of life measure.

Results: Utilizing nonrandom online surveys, this study included 305 …

Towards More Efficient Enhanced Sampling Methods To Study Phase Transitions, Kenneth Ndumbe Ngale

Theses and Dissertations

The most familiar phase transitions observed in nature are associated with a change in the state of matter (solid, liquid, and gas). In some rare cases this may involve the plasma phase. Such transitions are often referred to as first order phase transitions and often occur commonly such as during the melting of snow or freezing of lakes and rivers during winter. This project focuses on the most ubiquitous phase changes such as, liquid-solid and vapor-liquid as well as the less prevalent vapor-solid transitions. These types of phase transitions are also known as classical phase transitions. They usually involve symmetry …
