Performance Of Nitrogen As A Carrier Gas In Capillary Gas Chromatography Using A Thin Film Column, Brittany A. Handzo

Seton Hall University Dissertations and Theses (ETDs)

Gas chromatography (GC) is one of the most widely used analytical techniques for the separation and analysis of volatile compounds. Solids, liquids, and gases, organic and inorganic materials, and large molecular weight compounds can all be analyzed via this technique. Gas chromatographic separations are fast, accurate, and reliable. One of the reasons why these separations are so efficient is because of the carrier gas. The purpose of the carrier gas is to carry the injected sample through the column. It is known as the mobile phase and does not interact chemically with the sample. Common carrier gases include helium, hydrogen, …

Economic Engagement, Development, And Entrepreneurship: The Role Of Applied Public Service Colleges, Jason Jolley, Gilbert Michaud

eJournal of Public Affairs

This paper investigates the unique role of applied public service colleges in engaging with communities through economic development and entrepreneurship-related activities. Schools of public administration, affairs, and service are often distinctively tasked with being public facing, and connecting and working with outside agencies, nonprofits, and other stakeholders. Using a case study of Ohio University’s Voinovich School of Leadership and Public Affairs, we discuss the emerging engagement role of these types of schools through a typology of strategies brought forth by the Association of Public and Land Grant Universities. We outline seven specific programs run by the Voinovich School, and discuss …

Statistical Analysis Of Social Network Change, Teresa Danielle Schmidt

Dissertations and Theses

This project explores two statistical methods that infer social network structures and statistically test those structures for change over time: regression-based differential network analysis (R-DNA) and information theory-based differential analysis (I-DNA). R-DNA is adapted from bioinformatics and I-DNA employs reconstructability analysis.

This project applies both R-DNA and I-DNA to analyze Medicaid claims data from one-year periods before (May 2011- Apr 2012) and after (Jan 2013-Dec 2013) the formation of the Health Share of Oregon Coordinated Care Organization (CCO). The formation of CCOs was legislated by the state of Oregon in 2012 with the triple aim of improving health outcomes, reducing …

Seed‐To‐Seedling Transitions Exhibit Distance‐Dependent Mortality But No Strong Spacing Effects In A Neotropical Forest, Philippe Marchand, Liza S. Comita, S. Joseph Wright, Richard Condit, Stephen P. Hubbell, Noelle G. Beckman

Biology Faculty Publications

Patterns of seed dispersal and seed mortality influence the spatial structure of plant communities and the local coexistence of competing species. Most seeds are dispersed in proximity to the parent tree, where mortality is also expected to be the highest, because of competition with siblings or the attraction of natural enemies. Whereas distance‐dependent mortality in the seed‐to‐seedling transition was often observed in tropical forests, few studies have attempted to estimate the shape of the survival‐distance curves, which determines whether the peak of seedling establishment occurs away from the parent tree (Janzen–Connell pattern) or if the peak attenuates but remains at …

Rising Seas Are Coming For The Dead, Kristen Ancillotti

Capstones

When people think of preparing for a disaster, they focus on how to safeguard homes, prevent damage to roads, and create efficient flood drainage. But as sea levels rise, it’s not only the living that are affected. Coastal cemeteries are washing away or slowly turning into marshland, and in some instances, caskets can be seen floating in the streets after storms. Projections from NOAA indicate that the global mean sea level is likely to rise at least 12 inches by 2100, and in a worst case scenario in which greenhouse gas emissions are at their highest, as high as 8.2 …

Vintage Report 2019: North Willamette Valley, Gregory V. Jones

Linfield University Wine Studies Reports

This report describes the impacts of climate and phenology on vintage for the North Willamette Valley in Oregon in 2019. A relatively mild early winter in 2018 was followed by a cold and wet second half of winter in 2019 and then a wet, but warm, spring. The growing season saw a few mild frosts during late April, but started off warmer than average, moderating through mid-vintage with fewer than average heat spikes. Near-record precipitation amounts during late June and early July brought increased disease pressure to the region. The vintage will be remembered for the early rains in September …

City On The Edge: New York In The Age Of Climate Change, Janelle Little

Capstones

By 2030, 70% of the world’s population will live in cities.

The United Nations Intergovernmental Panel on Climate Change (IPCC) has singled out 2030, too - as a date of no return on climate change.

Our future quality of life in these adopted metropolises will depend on what we do to confront climate change now.

New York has always been a city of reinvention. City on the Edge examines how New York City is restructuring its urban landscape and policies to adapt to the realities of a changing climate and mounting existential threats, from sea level rise to escalating summer …

A Geographical Analysis Of Gentrification And The Changing Foodscape In Seattle 2010-2017, Alice Tiffany, Michele Romolini

Honors Thesis

Anguelovski defines food privilege as “the exclusive access to desirable ‘natural’ and fresh food thanks to one’s economic, cultural, and political power” (Anguelovski 2015a). Previous studies have demonstrated that access to fresh, healthy, affordable food is correlated with socioeconomic status (LA Food Policy Council 2017; Walker et al. 2010; Alkon & Agyeman 2011; Raja et al. 2008). However, as is being increasingly noted, the introduction of environmental amenities, such as farmers markets and community gardens, can have unintended consequences and trigger environmental gentrification (Kern 2015; Pearsall 2010; Eckerd 2011; Curran & Hamilton 2012; Wolch et al. 2014; Alkon & Cadji …

Visualization And Analysis Of Environmental Data, Sean Macdonald

Publications and Research

The virtual exploration of place has been employed in a variety of learning environments across many disciplines, creatively expanding upon the experience of place. This chapter explores the value of mapping environmental data as a tool that can enhance students’ virtual exploration of place as they investigate local environmental policies and problems within their own urban surroundings. This visualization project engages students in making meaningful connections between the theoretical study of local and global environmental problems and the “observation” and investigation of these data using mapped data. The virtual learning environment is viewed as one that is interactive, exploring how …

Implications Of The Modifiable Areal Unit Problem For Wildfire Analyses, Timothy P. Nagle-Mcnaughton, Xi Gong, Jose A. Constantine

Geography and Environmental Studies Faculty Publications

Wildfires pose a danger to both ecologies and communities. To this end, many large-scale analyses of wildfire patterns and behavior rely on the aggregation of point data to polygons, typically those based on distinct disparate ecological areas. However, the sizes, shapes, andorientations of the polygons to which data are aggregated are not neutral factors in the resulting analysis. The influence of the aggregation polygons on calculated results is known as the modifiable areal unit problem (MAUP), which is well-documented in the spatial statistics literature. Despite the documentation of the MAUP, relatively few wildfire studies consider the effects of the MAUP …

Plastic Packaging And The Associated Environmental Challenges. A Case For A California Plastic Packaging Framework, Zahra Ghayour-Kelly

Master's Projects and Capstones

While plastic has become an almost irreplaceable material in modern life, continuous new evidence of its adverse effects on human health and the environment is emerging. Currently there are limited options to address the negative impacts of plastic production and disposal on the environment. Plastic production and distribution creates greenhouse gas emissions. Additionally, limited end-of-life waste management options for the growing plastic waste stream place a great burden on local communities and the environment. Among the many products made of plastic, packaging is the largest and fastest-growing sector. Plastic packaging that is multilayered and fused is very commonly used, yet …

Understanding Microplastics In Freshwater: From Little Stream To Big River, Morgan Anderson

Geography: Student Scholarship & Creative Works

The purpose of this study is to better understand how microplastics move through rivers. Microplastics can come from various sources, but the main characteristic of them is their size. These plastics have diameters between 10 nanometers and 5mm. Because these particles are easily confused with food sources, ingestion and bioaccumulation of microplastics in many aquatic organisms has been a hot topic for concern (Besseling et al, 2017; Liedermann et. al, 2018; Nel et. al, 2018; Siegfried et. al, 2017; Windsor et. al, 2019). Ingestion of these microplastics can be detrimental to both human and ecological health due to pathogen accumulation …

Temporally Consistent Urban-Rural Delineations For Global Urban Heat Island Monitoring, Tc Chakraborty

Yale Day of Data

Urbanization leads to local-scale modification of climate, particularly the urban heat island (UHI) effect - the high temperature in cities compared to their surroundings. The UHI effect is generally quantified by measuring the temperature differential between the city and its surrounding rural reference. Choices of both the city and the rural reference are prone to assumptions, which may affect, among other things, temporal variability in UHI intensity. To reduce these uncertainties, I create a global dataset of urban-rural delineations that can be used to better constrain the temporal trends in UHI intensity throughout the globe using the European Space Agency's …
