Seasonal Shifts In Diet And Gut Microbiota Of The American Bison (Bison Bison), Gaddy T. Bergmann, Joseph Craine, Michael S. Robeson, Noah Fierer

United States Department of Agriculture Wildlife Services: Staff Publications

North American bison (Bison bison) are becoming increasingly important to both grassland management and commercial ranching. However, a lack of quantitative data on their diet constrains conservation efforts and the ability to predict bison effects on grasslands. In particular, we know little about the seasonality of the bison diet, the degree to which bison supplement their diet with eudicots, and how changes in diet influence gut microbial communities, all of which play important roles in ungulate performance. To address these knowledge gaps, we quantified seasonal patterns in bison diet and gut microbial community composition for a bison herd in …

Radiocarbon Dating Of Late Quaternary Sediments Using Fossil Gastropod Shells, Jeffrey S. Pigati, John P. Mcgeehin, Daniel R. Muhs

United States Geological Survey: Staff Publications

Terrestrial gastropods are one of the most successful groups of organisms on Earth. Their distribution includes all continents except Antarctica, and they occupy exceptionally diverse habitats, from marshes and wet meadows to alpine forests and Arctic tundra. Their shells are also commonly preserved in Quaternary deposits and potentially could be used for ¹⁴C dating. However, terrestrial gastropods are known to ingest limestone and incorporate the old carbon in their shells, resulting in apparent ages that are often too old. Recent studies have shown that many small (<1 cm diameter) terrestrial gastropods avoid this “limestone problem” even when living in areas in which carbonate rocks are readily available. However, the shells must also behave as closed systems with respect to carbon if their ages are to be considered reliable. Our latest work has been aimed at testing if small gastropod shells do, in fact, remain closed systems in late Quaternary deposits over a wide array of climate conditions across North America. Our results demonstrate that ages derived from Succineidae shells are identical to wood and charcoal ages in loess in Alaska, glacial deposits in the upper Midwest, loess in the Great Plains, and paleowetlands in the desert southwest. Moreover, Succineidae shell ages routinely fall within permitted limits set by stratigraphic boundaries, require less interpretation than humic acid ages that are commonly used in loess studies, can provide additional stratigraphic coverage to previous dating efforts, and maintain stratigraphic order more often than luminescence ages from the same stratigraphic intervals. Thus, we conclude that fossil Succineidae shells, and shells of a few other small gastropods, can be used for ¹⁴C dating regardless of the local lithology, past climate, or environmental …

Sea Level, Paleogeography, And Archeology On California's Northern Channel Islands, Leslie Reeder- Myers, Jon Erlandson, Daniel R. Muhs, Torben Rick

United States Geological Survey: Staff Publications

Sea-level rise during the late Pleistocene and early Holocene inundated nearshore areas in many parts of the world, producing drastic changes in local ecosystems and obscuring significant portions of the archeological record. Although global forces are at play, the effects of sea-level rise are highly localized due to variability in glacial isostatic adjustment (GIA) effects. Interpretations of coastal paleoecology and archeology require reliable estimates of ancient shorelines that account for GIA effects. Here we build on previous models for California's Northern Channel Islands, producing more accurate late Pleistocene and Holocene paleogeographic reconstructions adjusted for regional GIA variability. This region has …

Nutri One-On-One: The Assessment And Evaluation Of A Brief One-On-One Nutritional Coaching In Patients Affected By Metabolic Syndrome, Jennifer King, Jeffrey E. Harris, David Kuo, Farzaneh Daghigh

PCOM Scholarly Works

Nutri One-on-One was a program with the aim to positively modify medical clinic patients’ nutritional habits and lifestyles through a brief one-on-one health coaching session. Each session was conducted by utilizing motivational interviewing techniques to allow for tailored nutrition education and goal setting. These sessions were followed by a phone call to participants at 1 month following the session. The outcomes assessed were participant perception of achieving personal nutrition and lifestyle goals, retention of knowledge, and participants’ satisfaction with the program. Physicians working in the clinic were assessed for satisfaction with the program. Most of the physicians were generally satisfied …

Escaping Cascadia, Todd Albertson

University Honors Theses

The preface, "Dualism and Narrative Mode," details the development of realist techniques and then looks to current research to address the question, "In what other ways can realism be maximized within fiction?" It proposes a style combining second-person imperative narration for the viewpoint character’s actions and third-person free indirect discourse for description and internalization.

The introduction, "The Geography of the Future," explores prediction within select literary works, explains mitigation reactions to such predictions, and details current geographical projections to build a picture of what the future will look like and how humans will interact with their environment.

Escaping Cascadia is …

Refugial Isolation And Range Expansions Drive The Genetic Structure Of Oxyria Sinensis (Polygonaceae) In The Himalaya-Hengduan Mountains, Lihua Meng, Gang Chen, Zhonghu Li, Yongping Yang, Zhengkun Wang, Liuyang Wang

Graduate School of Oceanography Faculty Publications

The formation of the Mekong-Salween Divide and climatic oscillations in Pleistocene were the main drivers for the contemporary diversity and genetic structure of plants in the Himalaya-Hengduan Mountains (HHM). To identify the relative roles of the two historical events in shaping population history of plants in HHM, we investigated the phylogeographic pattern of Oxyria sinensis, a perennial plant endemic to the HHM. Sixteen chloroplast haplotypes were identified and were clustered into three phylogenetic clades. The age of the major clades was estimated to be in the Pleistocene, falling into several Pleistocene glacial stages and postdating the formation of the …

‘Water Is Life’: Exploring The Relationship Between Place Identity, Water And Adaptive Capacity In Fort Resolution, Northwest Territories, Canada, Jennifer A. Fresque-Baxter

Theses and Dissertations (Comprehensive)

Water is recognised as a fundamental human right in Canada’s Northwest Territories (NWT). However, the current and potential effects of climate change coupled with resource development pressures are leading to concerns about maintaining the health and viability of freshwater in the NWT. These intersecting multiple exposures can have far-reaching impacts for NWT residents who rely on water for cultural, spiritual, economic and social purposes. Ongoing changes (e.g., to water quantity, water quality, weather, precipitation and ice dynamics, for example) will increasingly require NWT residents to adapt, seek ways to plan for the future, identify opportunities, and moderate the effects of …

The research question was: "How do men and women who have a diagnosis of FM experience interactions with healthcare providers?" The study, which was epistemologically rooted in the critical theories of feminist poststructuralism and intersectionality, blended constructivist grounded theory with a participatory component, an arts-based research methodology called body-map storytelling. Thirty-five participants were recruited from the Greater Toronto Area and Kitchener-Waterloo. Ten participants completed in-depth interviews while 25 participants completed …

An Analysis Of Quality For Volunteered Geographic Information, Joel C H Meier

Theses and Dissertations (Comprehensive)

In recent years there has been a growing number of online user communities engaged in the creation, visualization, and use of volunteered geographic information (VGI). These data may represent an untapped resource for researchers analyzing large-area geographic phenomena such as species distributions patterns or land and resource management issues. However very few studies have used VGI for analytic research questions as little is known about the quality of these data. An understanding of the validity of VGI is a prerequisite for further exploitation of these novel data sources in research contexts. This paper looks to identify key issues related to …

Dune And Coastal Evolution In Isla Salamanca National Park, Colombia, Juan Felipe Gómez

Theses and Dissertations (Comprehensive)

This project analyzes natural variables influencing the coastal and dune evolution in Isla Salamanca National Park (ISNP), a biosphere reserve and Ramsar site located in Colombia, on the Caribbean coast. Since at least the early 1950s, the park has been affected by eroding trends along most of the shoreline. Particularly, most modern dunes are located close to the coastline, forming scarped dunes regularly affected by storm wave-action.

The trends through time of rain, bathymetry and coastline changes during the last six decades were studied through statistical analysis, mapping of landscape features, and satellite images and historical aerial photograph …

Parent Engagement Pedagogy And Practice In New Preservice Teacher Education Programs In Ontario, Tracy E. Bachellier

Theses and Dissertations (Comprehensive)

Parent engagement that focuses on building relationships and increasing social capital has a positive impact on student outcomes. However, one of the greatest challenges new teachers face is working with parents in support of children’s learning. The need to better prepare teachers points to an enhanced curriculum of parent engagement during preservice teacher education.

Ontario faculties of education were surveyed regarding planned implementation of new accreditation guidelines for parent engagement. Document reviews of existing and modified teacher education programs were conducted. Participants reported parent engagement pedagogy in modified programs had somewhat increased and believed teacher candidates would be ‘somewhat’ to …

Affective Migration: The Role Of Food Preparation And Visceral Experience For Egyptian Migrant Women Settling In The Region Of Waterloo, Mary Neil

Theses and Dissertations (Comprehensive)

This study examining Egyptian migrants settling in Canada is exploratory in nature and is intended to initiate a conversation about the personal experience of transnationalism and the value of the body as an instrument of research. A semi-structured interview approach was designed to prompt the evocation of deep personal thoughts, experiences, and sensations in response to questions surrounding migration to Canada through the shared performative act of cooking and the visceral experience of eating in the private space of the migrant kitchen. Using a grounded theory approach, several adaptive mechanisms were identified such as the creation of manageable daily routines, …

Neither War, Nor Peace: Everyday Politics, Peacebuilding And The Liminal Condition Of Bosnia-Herzegovina And Northern Ireland, Branka Marijan

Theses and Dissertations (Comprehensive)

This thesis focuses on cultural and everyday practices of local populations in post-conflict peacebuilding. It builds on the “everyday” turn in critical peacebuilding literature by recognizing the everyday as political. Rather than examining the practices of political elites this thesis is concerned with the ordinary citizens of these societies. In other words, I show that it is through practices and cultural forms of expression that local populations enact their agency, at times supporting and at times contesting the broader peacebuilding project. Moreover, rather than viewing the everyday acts as hidden or as evidence of resistance to the dominant peacebuilding approaches …

A Critical Review Of Ontario’S Blue Box Program: Identifying And Testing Best Practices In Printed Paper And Packaging Recycling, Calvin Lakhan

Theses and Dissertations (Comprehensive)

This dissertation undertook a critical review of four recycling policies used in Ontario which are designed to promote household waste diversion and reduce material management costs. These policies include:

1) Municipal funding should be directly tied to program performance relative to their peer group. 2) All municipalities should make investments in recycling promotion and education, and will be reimbursed $1 per household for all recycling promotion and education expenditures

3) Where possible, municipalities should implement pay as you throw schemes for household waste as a means to minimize the amount of material being disposed of in the waste stream.

4) …

Non-Refoulement In A World Of Cooperative Deterrence, Thomas Gammeltoft-Hansen, James C. Hathaway

Articles

Developed states have what might charitably be called a schizophrenic attitude towards international refugee law. Determined to remain formally engaged with refugee law and yet unwavering in their commitment to avoid assuming their fair share of practical responsibilities under that regime, wealthier countries have embraced the politics of non-entrée, comprising efforts to keep refugees away from their territories but without formally resiling from treaty obligations. As the early generation of non-entrée practices — visa controls and carrier sanctions, the establishment of “international zones,” and high seas deterrence — have proved increasingly vulnerable to practical and legal challenges, new forms of …

Correcting Corporate Benefit: How To Fix Shareholder Litigation By Shifting The Doctrine On Fees, Sean J. Griffith

Faculty Scholarship

The current controversy in corporate law concerns whether firms can discourage litigation by shifting its cost to shareholders. But corporate law courts have long engaged in fee-shifting—from shareholder plaintiffs to the corporation—under the “corporate benefit” doctrine. This Article examines fee-shifting in share-holder litigation, arguing that current practices are unsound from the perspective of both doctrine and public policy. Unfortunately, the fee-shifting bylaws recently enacted in response to the problem of excessive shareholder litigation fare no better. The Article therefore offers a different approach to fee-shifting, articulating three specific reforms of the corporate benefit doctrine to quell the current crisis in …

Disappearing Legal Black Holes And Converging Domains: Changing Individual Rights Protection In National Security And Foreign Affairs, Andrew Kent

Faculty Scholarship

This Essay attempts to describe what is distinctive about the way the protection of individual rights in the areas of national security and foreign affairs has been occurring in recent decades. Historically, the right to protection under the U.S. Constitution and courts has been sharply limited by categorical distinctions based on geography, war, and, to some extent, citizenship. These categorical rules carved out domains where the courts and Constitution provided protections and those where they did not. The institutional design and operating rules of the national security state tracked these formal, categorical rules about the boundaries of protection. There have …

Shortfalls And Solutions For Meeting National And Global Conservation Area Targets, Stuart H. M. Butchart, Martin Clarke, Robert J. Smith, Rachel E. Sykes, Jorn P. W. Scharlemann, Mike Harfoot, Graeme M. Buchanan, Ariadne Angulo, Andrew Balmford, Bastian Bertzky, Thomas M. Brooks, Kent E. Carpenter, 28 Others

Biological Sciences Faculty Publications

Governments have committed to conserving greater than or equal to 17% of terrestrial and greater than or equal to 10% of marine environments globally, especially "areas of particular importance for biodiversity" through "ecologically representative" Protected Area (PA) systems or other "area-based conservation measures", while individual countries have committed to conserve 3-50% of their land area. We estimate that PAs currently cover 14.6% of terrestrial and 2.8% of marine extent, but 59-68% of ecoregions, 77-78% of important sites for biodiversity, and 57% of 25,380 species have inadequate coverage. The existing 19.7 million km super(2) terrestrial PA network needs only 3.3 million …

Steps In Metagenomics: Let’S Avoid Garbage In And Garbage Out, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Is metagenomics a revolution or a new fad? Metagenomics is tightly associated with the availability of next-generation sequencing in all its implementations. The key feature of these new technologies, moving beyond the Sanger-based DNA sequencing approach, is the depth of nucleotide sequencing per sample.Knowing much more about a sample changes the traditional paradigms of “What is the most abundant?” or “What is the most significant?” to “What is present and potentially sig­nificant that might influence the situation and outcome?” Let’s take the case of identifying proper biomarkers of disease state in the context of chronic disease prevention. Prevention has been …

The Role Of Information Technology Organizational Design In Firms' Ability To Innovate, Hassan S. Halimi

Walden Dissertations and Doctoral Studies

Information technology (IT) organizations have become an integral part of many firms, with increasing strategic significance. Consequently, investments in IT represent a significant percentage of a firm's expenditure. Despite the investment, the business value of IT has been difficult to quantify, creating uncertainty about a firm's investments in IT innovation. The purpose of this nonexperimental study was to examine relationships between a firm's innovativeness and 3 IT organizational design factors: knowledge creation, dynamic capabilities, and communication structures. The research questions addressed the relationships between a firm's ability to innovate and specific design elements of the IT organization. The study was …

Lived Experiences Of Military Personnel Reintegrating With Their Preschool Aged Children, Rob Atchison

Walden Dissertations and Doctoral Studies

Researchers have indicated that school-aged children with a caregiver who had been deployed were more likely to exhibit emotional and behavioral problems. These problems were impacted by the ability of the parent at home to manage emotions so as to utilize appropriate parenting skills with the child. However, there remained an important gap in the literature regarding the experiences of the military personnel reintegrating with their preschool aged child. Therefore, the purpose of this phenomenological study was to address the experiences of military caregivers with their preschool-aged children through semistructured interviews to better understand the variables that impacted the ability …

Cultural Backgrounds Influencing Virtual Team Performance, Vyacheslav Semenovich Lerner

Walden Dissertations and Doctoral Studies

Virtual teams improve organizational performance and competitiveness because they reduce business travel and allow team members to work from anywhere, anytime, using the Internet to complete projects. Although researchers have identified benefits of using virtual teams, knowledge about how cultural backgrounds influence virtual team performance is limited. Illuminating this relationship may help leadership improve team performance. The purpose of this phenomenological study was to explore the lived experiences of team members with different cultural backgrounds to understand their effect on team performance. The research questions were based on the conceptual framework of organizational cultural theories developed by Schein and Trompenaars …

Port Security: The Terrorist Naval Mine/Underwater Improvised Explosive Device Threat, Peter Von Bleichert

Walden Dissertations and Doctoral Studies

Terrorist naval mines/underwater improvised explosive devices (M/UWIEDs) are a threat to U.S. maritime ports, and could cause economic damage, panic, and mass casualties. The purpose of this case study was to examine this threat and propose reforms that improve port security management. The study aligned with the mission area analysis objective of identifying and assessing potential terrorist threats in order to preempt and prevent attacks. Von Bertalanffy's general systems theory was the framework for research questions, which focused on improvements in port security management to mitigate the threat of terrorist M/UWIEDs. Data collection included a document content analysis of open …

A Case Study Investigating Secondary Science Teachers' Perceptions Of Science Literacy Instruction, Phyllis Ann Blackmon

Walden Dissertations and Doctoral Studies

This project study addressed the lack of inclusion of discipline literacy pedagogy in secondary classrooms in a rural school district in eastern North Carolina. Discipline literacy practices are recommended in the Common Core Standards for History/Social Studies, Science, and Technical Subjects. The district had implemented content area reading strategies across content areas, yet no significant progress in secondary students' reading abilities had been demonstrated in statewide or national assessments. The conceptual framework that drove this study was disciplinary literacy, founded by the literacy research of Shanahan, Shanahan, and Zygouris-Coe. Within a qualitative case study method, this investigation of 8 secondary …

Survival Analysis Of Total Therapy 3 In Newly Diagnosed Multiple Myeloma, Scott Edward Bowman Miller

Walden Dissertations and Doctoral Studies

Multiple Myeloma (MM) is a hematologic malignancy that accounts for approximately 1% of all adult cancers. This study investigated the impact of patient distance traveled to MM care sites, which was not considered in previous research on any disease-specific staging or prognostic schema despite evidence suggesting that distance impacts patient outcome. This study investigated the impact of patient distance from the site of care on survival outcomes using a group of 480 clinical trial participants. Andersen's behavioral model of health services use functioned as the theoretical model for this study. The independent variable was patient travel distance, controlling for established …

The Barriers Encountered In Telemedicine Implementation By Health Care Practitioners, Olantunji Obikunle

Walden Dissertations and Doctoral Studies

Patients in rural areas in the United States do not have adequate health care facilities for illnesses and injuries not serious enough for emergency care, but telemedicine could have a positive impact both economically and medically to control rapidly rising health care costs, which is a significant percentage of the gross national product. The purpose of this case study was to explore the barriers physicians encountered in telemedicine implementation. Participants included 4 physicians who took part in face-to-face interviews in a clinical setting in Ohio to explore strategies used in implementing telemedicine. The results of these interviews, coupled with observations …
