Green Cities And Waste Management: The Restaurant Industry, Minoo Tehrani, Lawrence Fulton, Bryan Schmutz
Green Cities And Waste Management: The Restaurant Industry, Minoo Tehrani, Lawrence Fulton, Bryan Schmutz
Business Faculty Publications
“Green Cities” are cities with the ultimate goal of achieving a net zero-carbon footprint in energy, transportation, architecture, and the activity cost chain of businesses. These cities define the future of our planet by emphasizing the efficient use of resources and the well-being of communities. This study focuses on “Green Cities” and the restaurant industry. It examines the beliefs of restaurant owners/managers on the positive impact of sustainability practices on financial situation, reputation, and attraction of customers, and the relationship between such beliefs and the extent of engagement in sustainability practices. The research also explores whether declaring a city “Green” …

Posters As An Effective Assessment Tool For A Capstone Course, David Gosselin, Doug Golick
Department of Entomology: Faculty Publications
A rubric was developed to assess student posters as a mechanism to evaluate learning outcomes for a senior capstone course. The analytic rubric allows for the efficient and systematic collection of data from posters by students who worked across a variety of disciplines including the physical, biological, Earth sciences, social science, and the humanities. The rubric effectively addressed a fundamental assumption and requirement put forth during rubric development, that is, it needs to be relatively easy to use without training while at the same time producing consistent results across evaluators. The overall Chronbach’s alpha of 0.80 across semesters indicates acceptable …

Department of Food Science and Technology: Faculty Publications
Water bloom development due to eutrophication constitutes a case of niche specialization among planktonic cyanobacteria, but the genomic repertoire allowing bloom formation in only some species has not been fully characterized. We posited that the habitat relevance of a trait begets its underlying genomic complexity, so that traits within the repertoire would be differentially more complex in species successfully thriving in that habitat than in close species that cannot. To test this for the case of bloom-forming cyanobacteria, we curated 17 potentially relevant query metabolic pathways and five core pathways selected according to existing ecophysiological literature. The available 113 genomes …
Synthesis, Magnetic And Adsorption Of Dye Onto The Surface Of Nio Nanoparticles, Islam Gomaa, Nasser M. Hosny
Synthesis, Magnetic And Adsorption Of Dye Onto The Surface Of Nio Nanoparticles, Islam Gomaa, Nasser M. Hosny
Nanotechnology Research Centre
NiO was synthesized simply via thermal decomposition of nickel ascorbate, which resulted from semi-solid reaction of nickel acetate and ascorbic acid. The prepared precursor was characterized by elemental, thermal and spectral analyses. The precursor was decomposed at 700 °C producing cubic NiO with average size 50 nm as indicated from XRD and TEM. FESEM indicated the formation of macroporous NiO. Magnetic parameters (saturation magnetization (Ms), remanence (Mr) and coercivity (Hc)) of NiO nanoparticles and its precursor were determined and compared with the bulk nickel. Zeta potential measurements at different pH values indicated that NiO is negatively charged. Adsorption of ponceau …

Constraints On Phytoplankton Abundance And Cyanotoxin Production In The Tidal Freshwater James River, Brittany Ann Moretz
Constraints On Phytoplankton Abundance And Cyanotoxin Production In The Tidal Freshwater James River, Brittany Ann Moretz
Theses and Dissertations
The tidal freshwater James River exceeds chlorophyll-a (CHL-a) water quality standards and the cyanotoxin microcystin is commonly present. Efforts to control harmful algal blooms in the James have brought about significant reductions in nitrogen and phosphorus inputs, but chlorophyll levels have not changed. In order to better understand the factors constraining harmful algal blooms in this system, we performed three factorial mesocosm experiments that tested how light (ambient, enhanced), mixing (weak mixing, well-mixed), and the availability of dissolved inorganic nitrogen (pre/post NH4+ reductions) influence the abundance of phytoplankton (CHLa, particulate organic carbon [POC]) and cyanotoxin production (microcystin, anatoxin) …
Design Hub: Activating Community By Design, Ed Williams
Design Hub: Activating Community By Design, Ed Williams
Theses and Dissertations
MOTIVATION
At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”
This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …
Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan
Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan
Theses and Dissertations
Budgets are a prospective tool of governance, and appropriations are a planning vehicle reflecting: bureaucracies’ values, complex interactions, collective preferences, political influences, and available resources. Research spanning 30 years finds that environmental pollution is a key determinant of environmental budgets in the US, though myriad factors, actors, and subsystems are important to consider. Due to federalism and devolution of responsibilities and authorities, environmental governance falls largely to the states. While the dynamics that shape state environmental budget policy have received scholarly interest, theoretically-driven examinations of environmental appropriations remain limited within the public budgeting and environmental policy literature.
Using panel data …
The Influence Of Breeding Density On Female Aggression, Parental Care, And Ornamentation In A Secondary-Cavity Nesting Warbler, Elsa B. Chen
The Influence Of Breeding Density On Female Aggression, Parental Care, And Ornamentation In A Secondary-Cavity Nesting Warbler, Elsa B. Chen
Theses and Dissertations
Tradeoffs between individual survival and reproductive success associated with aggressive behaviors are a driving force of evolution, but these tradeoffs are often overlooked for aggressive conspecific interactions between females. For avian males, it is well documented that more aggressive individuals tend to provide less parental care. In the few studies that address this in females, the tradeoffs seem to be more context-dependent, varying due to factors such as predation pressure and habitat quality. The relationship between female ornamentation and aggression is similarly understudied, but evidence suggests that both aggression and ornamentation are important traits involved in social selection – the …
Comparing Coastal Storm Impact To Decadal Change In Barrier Island Ecosystems, Philip A. Tuley
Comparing Coastal Storm Impact To Decadal Change In Barrier Island Ecosystems, Philip A. Tuley
Theses and Dissertations
Highly dynamic coastal systems respond to disturbance events with a combination of topographic and vegetative changes. Sea level rise impacts on barrier islands have been quantified, but storm effects on vegetation are limited. Here we quantified barrier island vegetation change in response to an isolated storm event and compared to long-term periods. We hypothesized that disturbance-resisting areas with high woody vegetation cover and/or high foredune elevation would experience minimal transitions after a storm event, whereas disturbance-reinforcing areas with low vegetation cover and low foredune elevation would experience greater transitions between ecosystem states after a storm event. Patterns of dissonance were …
Plant-Pollinator Associations In An Eastern Serpentine Savannah And The Effects Of Overbrowsing, Allyson Richins
Plant-Pollinator Associations In An Eastern Serpentine Savannah And The Effects Of Overbrowsing, Allyson Richins
Theses and Dissertations
Chapter 1: Native plant response to deer overbrowsing in a serpentine savannah
Plants are particularly vulnerable to physical disturbance in low productivity areas, due to a high cost of replacing lost plant tissue. In the eastern United States, serpentine grasslands are fragmented ecosystems with high concentrations of rare endemic plant species, low concentrations of soil nutrients, and uncontrolled deer overpopulation. This study assessed functional responses of native angiosperms in a rare eastern serpentine savannah to selective deer browsing. Plant count, flower count, floral area, vegetative area, and plant height of 10 serpentine plant species were compared inside and outside of …
Assessing The Feasibility Of Freshwater Mussel Restoration In Urban Streams., John-Reid Ryan
Assessing The Feasibility Of Freshwater Mussel Restoration In Urban Streams., John-Reid Ryan
Theses and Dissertations
Abstract
The main objective of this study was to determine whether introduced freshwater mussels (Alewife floater, Utterbackiana implicata) can survive and grow in urban streams in the James River watershed. A secondary objective was to assess differences in U. implicata survival and growth of in the context of differing water quality and food resource conditions among three urban sites and three rural sites. Results from this study show large differences in growth and survivorship of mussels across sites. Higher survivorship was observed among mussels stocked into rural streams (35% and 44%) in comparison to urban streams (3%, 6% and 14%). …
Human Dimensions Research For Informed Decisions About Aquatic Restoration In New Hampshire: Environmental Justice In Implementation Of Compensatory Mitigation, Simone Tania Chapman
Human Dimensions Research For Informed Decisions About Aquatic Restoration In New Hampshire: Environmental Justice In Implementation Of Compensatory Mitigation, Simone Tania Chapman
Master's Theses and Capstones
New Hampshire’s aquatic resources provide many important ecosystem services and values, such as recreation, wildlife habitat, flood storage, nutrient reduction, community identity and aesthetic enjoyment. However, the many competing interests that seek to benefit from New Hampshire’s aquatic resources present challenges for efforts to steward public aquatic resources in the public interest. This thesis presents findings about the environmental justice outcomes of New Hampshire’s compensatory mitigation program, the Aquatic Resource Mitigation (ARM) fund, to inform aquatic restoration policy.
Previous studies have found evidence that aquatic restoration programs can lead to systemic resource relocation and patterns of inequality in outcomes. Using …
Can Farmers And Bats Co-Exist? Farmer Attitudes, Knowledge, And Experiences With Bats In Belize, Hannah G. Shapiro, Adam S. Willcox, Mallory Tate, Emma V. Willcox
Can Farmers And Bats Co-Exist? Farmer Attitudes, Knowledge, And Experiences With Bats In Belize, Hannah G. Shapiro, Adam S. Willcox, Mallory Tate, Emma V. Willcox
Human–Wildlife Interactions
Bats (Chiroptera) are often viewed negatively by the public. Negative public perceptions of bats may hinder efforts to conserve declining populations. In Belize, the presence of vampire bats (Desmodus rotundus and Diphylla ecaudata) exacerbates the potential for conflicts with humans because of the increased rabies transmission risks. To mitigate these risks, the Belize government provides farmers with assistance to trap and remove vampire bats. In June 2018, we surveyed farmers (n = 44) in and adjacent to the Vaca Forest Reserve in Belize to learn more about their attitudes, knowledge, and experiences with bats. This information may …

Domestic Violence In Culturally And Linguistically Diverse (Cald) Communities: Perceptions, Therapeutic Approaches And Responses Of Frontline Workers In New South Wales (Nsw), Oluwatoyin A. Dedeigbo
Domestic Violence In Culturally And Linguistically Diverse (Cald) Communities: Perceptions, Therapeutic Approaches And Responses Of Frontline Workers In New South Wales (Nsw), Oluwatoyin A. Dedeigbo
Theses
Domestic violence is a universal public health concern (VicHealth, 2011; World Health Organisation [WHO], 2013). Domestic violence cuts across all countries, regardless of economic, social, cultural or religious differences (Ali et al., 2020; VicHealth, 2011; WHO 2013). Men are often responsible for perpetrating domestic violence against women (Australian Bureau of Statistics [ABS], 2019; Australia Institute of Health and Welfare [AIHW], 2018).
The effects of domestic violence on victims can be serious and long-term; affecting their physical and mental wellbeing, and lingering even after the exposure to violence has ended (Mitchell, 2011). That is, the effect on victims’ mental health is …
The Political Viability Of Carbon Pricing: Policy Design And Framing In British Columbia And California, Roger Karapin
The Political Viability Of Carbon Pricing: Policy Design And Framing In British Columbia And California, Roger Karapin
Publications and Research
The adoption of climate policies with visible, substantial costs for households is uncommon because of expected political backlash, but British Columbia's carbon tax and California's cap-and-trade program imposed such costs and still survived vigorous opposition. To explain these outcomes, this paper tests hypotheses concerning policy design, framing, energy prices, and elections. It conducts universalizing and variation-finding comparisons across three subcases in the two jurisdictions and uses primary sources to carry out process tracing involving mechanisms of public opinion and elite position taking. The paper finds strong support for the timing of independent energy price changes, exogenous causes of election results, …
Influence Of Environmental Strategy And Management Control On Environmental And Economic Performance, Kanya Sannamwong
Influence Of Environmental Strategy And Management Control On Environmental And Economic Performance, Kanya Sannamwong
Chulalongkorn University Theses and Dissertations (Chula ETD)
This study aims to explore the role of eco-controls in translating competitive environmental strategic intents into eco-practices, as well as the associations between eco-practices and environmental and economic performance. A web-based survey was used to collect data from 151 Thai manufacturing firms from September to November 2020. Structural Equation Modeling (SEM) was employed for data analysis. The findings from the study suggest that firms pursuing predominantly eco-efficiency intent, firms pursuing predominantly eco-branding intent, and firms pursuing both eco-efficiency intent and eco-branding intent at the same degree, tend to adopt more bureaucratic forms of eco-control regardless of their environmental strategic intents. …
Birth Outcomes Associated With Heavy Metal Exposures In The Surroundings Of A Former Chemical Plant In Târnăveni, Romania, Jenny Wai Kun
Birth Outcomes Associated With Heavy Metal Exposures In The Surroundings Of A Former Chemical Plant In Târnăveni, Romania, Jenny Wai Kun
Public Health Theses
Heavy metal exposures have long been a public health concern, research on this field may promote policies and regulations to restrict or limit certain industrial practices. This study aims to evaluate potential associations between toxic heavy metal exposures via contaminated environmental media and the frequency of the birth defects in the designated area: Tarnaveni, Romania; historically contaminated by a former chemical plant. In 2018, a pilot investigation conducted on the site demonstrated that chromium (Cr), lead (Pb), and manganese (Mn) are common heavy metal contaminants found. Soil concentrations for all three metals exceeded normal background levels according to Romanian Environmental …

Resident Perceptions Of Human–Beaver Conflict In A Rural Landscape In Alberta, Canada, Nicholas T. Yarmey, Glynnis A. Hood
Resident Perceptions Of Human–Beaver Conflict In A Rural Landscape In Alberta, Canada, Nicholas T. Yarmey, Glynnis A. Hood
Human–Wildlife Interactions
The North American beaver (Castor canadensis) plays a key ecological role in wetland systems, yet their activities can result in costly damage to human infrastructure. Although qualitative research on human perceptions of beavers is rare, studies on human–beaver conflict in the United States identified generally positive attitudes toward beavers and opposition to lethal management, yet in Alberta, Canada, 79% of municipalities that managed beavers reported using trapping and shooting to remove problem beavers. Given the important ecological contributions of beavers and their potential conflict with humans, qualitative research is needed to assess perspectives of stakeholders who directly experience …
Taxa Specific Responses To Flooding Shape Patterns Of Abundance In A River Rock Pool Metacommunity, Charles R. Stunkle
Taxa Specific Responses To Flooding Shape Patterns Of Abundance In A River Rock Pool Metacommunity, Charles R. Stunkle
Theses and Dissertations
Connectivity and habitat area are important landscape characteristics that drive patterns of abundance and diversity across scales. However, responses to connectivity and patch size are dependent on species traits. Riverine landscapes are highly dynamic both spatially and temporally with hydrologic connectivity being a major driver of abundance and diversity. Here we modeled densities of the Virginia river snail and skimmer dragonfly nymphys, two taxa with differences in their dispersal abilities and life histories, as a function of flooding, patch area, and season in over 300 riverine rock pools. We found key differences in how each taxon responded to these predictors …
Evidence Of Local Adaptation To Climate In An Invasive Ectotherm: A Study On The Eurasian Gypsy Moth (Lymantria Dispar) In North America, Phillip M. Gibbs
Evidence Of Local Adaptation To Climate In An Invasive Ectotherm: A Study On The Eurasian Gypsy Moth (Lymantria Dispar) In North America, Phillip M. Gibbs
Theses and Dissertations
Invasive species exist in nearly every ecosystem both terrestrial and aquatic. Improving our understanding of the mechanisms that shape the ability of these organisms to physiologically cope with their surroundings will be crucial to preparing for future impacts of climate change. The Gypsy Moth (Lymantria dispar) has been expanding its range across North America over the last 100+ years since its arrival in Medford, Massachusetts. This study quantifies upper thermal limits (UTL) across 8 different populations of L. dispar in North America and seeks to determine if signals of local adaptation to climate across a latitudinal gradient may …
Analysis Of Teaching Styles, Adult Learning Theories, And Factors Influencing Teaching Style Preferences In Adult Education Instructors: Implication For Practice, Beatrice Chemaiyo Lele
Analysis Of Teaching Styles, Adult Learning Theories, And Factors Influencing Teaching Style Preferences In Adult Education Instructors: Implication For Practice, Beatrice Chemaiyo Lele
Theses and Dissertations
The teacher is the most influential and important variable in the classroom for student achievement. Therefore, the need for teachers to identify and utilize best teaching practices is fundamental to a progressing society. Despite the literature advocating and proposing the student-centered approach as the preferred method of teaching in adult education, most empirical studies indicate that teachers employed the traditional teacher-centered approach. The purpose of this study was to examine the teaching style preferences of adult education instructors and the influence of gender, age, participation in professional development in adult education, years of teaching experience, teaching subject, and levels of …
Regional Drivers Of Organic Carbon Age In Lotic Systems Of The Conterminous United States, Kaycee Faunce
Regional Drivers Of Organic Carbon Age In Lotic Systems Of The Conterminous United States, Kaycee Faunce
Theses and Dissertations
Rivers play a critical role in global carbon (C) budgets despite their comparatively small surface area. A significant portion of the terrestrial C that they receive is transformed, re-mineralized, or stored during transit to the ocean. Radiocarbon (∆14C) data show that a fraction of riverine organic C (OC) has been pre-aged in the terrestrial environment. Lateral export of carbon from these aged pools may contribute to atmospheric carbon dioxide emissions through microbial and photochemical oxidation. However, little is known about the regional climatic, anthropogenic, and landscape factors that promote the mobilization of aged OC to rivers. This study …
