Human Performance In Manufacturing Tasks: Optimization And Assessment Of Required Workload And Capabilities, Maria Chiara Leva, Lorenzo Comberti, Micaela Demichela, Alberto Caimo

Conference papers

This paper discusses some examples where human performance and or human error prediction was achieved by using a modified version of the Rasch model(1980), where the probability of a specified outcome is modelled as a logistic function of the difference between the person capacity and item difficulty. The model needs to be modified to take into account an outcome that may not be dichotomous and o take into account the interaction between two macro factors: (a) Task complexity: that summarises all factors contributing to physical and mental workload requirements for execution of a given operative task & (b) Human capability: …

Why Csas Matter: (Re)Localizing For People-Based Food Networks, Gretchen Alexander

Scripps Senior Theses

This thesis details the history of Claremont Market Shares, a Community Sourced Agriculture (CSA) project based out of Claremont, California. By using this project as a jumping off point for discussing local food networks, buzzwords such as "organic" and "local" are analyzed and re-defined. I argue for a people-based food network model over the currently popular 'place-based' that prioritizes producer-consumer relationships. The CSA functions as a sustainable model of this ideology.

Best Practices To Encourage Landfill Diversion In Waste Management Programs, Sondra Abruzzo

Scripps Senior Theses

Waste generation in the United States is at an all time high. Over half of the country’s waste goes to landfill, yet 70 percent of this waste can be recycled or composted. Since landfills pose one of the largest manmade threats to the environment, sustainable waste management strategies should focus on landfill diversion. A successful waste recovery program needs to engage the public, and ensure individuals participate correctly in available waste management systems. This paper sheds light on effective education and awareness strategies used to encourage participation in local waste management systems and promote landfill diversion. By highlighting successful programs …

Whitewater Ecotourism Development In Bhutan: Opportunities And Challenges For Local Communities, Kira E. Tenney

Graduate Student Theses, Dissertations, & Professional Papers

Whitewater raft and kayak ecotourism can provide environmental, social-cultural, and economic benefits and opportunities to local communities, but can also result in respective challenges. Globally, adventure ecotourism is seen as a potent win-win strategy for conservation and local community development; however, there is a significant proportion of adventure and whitewater tourism that do not meet ecotourism tenets, and there is a call for incorporating greater investment in local community involvement. Whitewater ecotourism is particularly significant because of the unique opportunities and challenges associated with rivers, the resource upon which the industry directly depends. Clean, free-flowing rivers provide a range of …

Learners With Disabilities Can Contribute To Waste Management, Arvie S. Andal, Maria Corazon C. Colendrino, Monaliza U. Guce-Vinas

Angelo King Institute for Economic and Business Studies (AKI)

Encouraging the community to shift into a more environmentally friendly practice would entail a consideration of several factors, more so if it includes the participation of individuals with disabilities. The result of the study highlights several actions needed to maximize the potential of the program: 1) the continuous training of learners with disabilities to build capacity and capability; and continuous funding for such; 2) the continuous improvement of product quality to meet specific market needs; and 3) the development of programs to increase the community’s awareness, understanding, and appreciation of the benefits of recycling.

The Decision To Decentralize Good Provision In The United States: A Study In Clean Energy Policy, Whitney Michelle Davis

Theses and Dissertations--Public Policy and Administration

Normative economic theory provides justification for at least partially centralized renewable energy provision due to the large, positive externalities associated with renewable energy production. However, the United States is one of the few countries without centralized renewable energy policy. Instead, the federal government actively chooses decentralized renewable energy provision by using fiscal transfers to support subnational renewable energy development. This dissertation explores why U.S. legislators choose decentralized renewable energy provision by asking two primary questions. First, what is the motivation for using federal fiscal transfers for decentralized renewable energy output considering what we know about positive spillovers and market failure …

Successful Climate Change Strategies In Corporate Farming, Deann Renee Reaves

Journal of Sustainable Social Impact

According to the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information (2016), climate-related disasters occurring from 2011 to 2015 caused property damages in excess of US$230 billion—and the agriculture sector incurs some of the largest losses (Hoffmann, 2013). The purpose of this case study was to identify, through an in-depth interview and document review, successful climate-change-based sustainability strategies in a publicly held farming operation. The findings indicated that the farm’s climate-change-based sustainability strategy had basic qualities of corporate social responsibility, triple-bottom-line thinking, and systems thinking. Specific approaches identified were mitigation- and adaptation-oriented approaches. Implications for social change include …

On The Brink Of Extinction: The Fate Of The Pacific Northwest's Southern Resident Killer Whales, Sabrina Wilk

Pomona Senior Theses

The killer whales that roam the northeastern Pacific Ocean have been the objects of studies since the 1970s, making them the most well-studied population of orcas in the world. Three distinct ecotypes of killer whales (Orcinus orca), known as residents, transients, and offshores, share these waters. The ecotypes are morphologically and behaviorally distinct to the extent that some scientists consider them separate species, with residents eating salmon, transients specializing on marine mammals, and offshores preferring Pacific sleeper sharks and Pacific halibut. Resident populations have endeared themselves to the region's locals with their striking black and white markings and …

Fragile Oceans, Synthetic Flotsam And Microbial Collaboration – Explorations In The Visual Communication Of The Plastic Crisis, Ivan Langesfeld

Pomona Senior Theses

Scientific evidence that the ocean plastic crisis is larger in scale and more sinister than previously thought continues to mount, but the rate of plastic production is only rising. What will it take to decisively turn the tide against plastic? We need scientists, politicians, and industry changemakers to continue producing knowledge and positive change in the industry, but we need to go further still. This thesis explores art as an alternative visual communication strategy with the capacity to encourage curiosity, empathy, and positive engagement with the issue of ocean plastics. The series of work explores bacterial bioluminescence as an artistic …

Restoring Reciprocity: Indigenous Knowledges And Environmental Education, Mireya Valencia

Pomona Senior Theses

Environmental education in the U.S. has been slow to incorporate Indigenous knowledges, with most pre-university curriculum centering around Western science. I believe incorporating Indigenous knowledges into environmental education can promote reciprocal, critical, and active human-nature relationships. While Indigenous knowledges should infiltrate all levels of environmental education, I argue that alternative forms of education which operate outside the formal school system might present the fewest immediate obstacles.

Ngos As Innovators In Extractive Industry Governance. Insights From The Eiti Process In Colombia And Peru, Elisa Arond, Anthony J. Bebbington, Juan Luis Dammert

Geography

This paper explores NGO participation within the Extractive Industries Transparency Initiative (EITI), a multi-stakeholder governance arrangement focused on generating greater transparency in the governance of extractive industries, and in particular in fiscal arrangements around mining, oil and gas operations. Using the cases of Peru and Colombia, we examine what motivates NGO participation in EITI, how NGOs have pursued innovations within EITI, the extent to which they have succeeded in achieving their goals, and the factors limiting or shaping their achievements. We draw on interviews conducted between 2013 and 2018, participation in global EITI meetings, and secondary material. The paper examines …

Accounting For Intermediaries And Transnational Linkages In The Multi-Level Perspective: Mongolia’S Renewable Energy Transition, Madeline Lee

CMC Senior Theses

As the international community takes increasing action to mitigate the effects of climate change, increased focus has been placed on the topic of energy transitions in developing countries. This paper uses the multi-level perspective (MLP) framework to analyze the ongoing energy transition in Mongolia, specifically the integration of large-scale wind and solar energy systems. Attention is paid to the presence of transnational linkages and intermediaries that have substantially contributed to Mongolia’s success in diffusing renewable energy technology, as well as challenges Mongolia has faced as a result of limited technological and institutional capacity. The paper concludes that Mongolia’s transition shares …

Leveraging Trade Agreements To Reduce Greenhouse Gas Emissions In Accordance With The Paris Agreement, Sam Becker

CMC Senior Theses

Climate change is the most obvious and pressing impairment of the biological, physical, and chemical systems. To help mitigate this unprecedented problem, I present heads of state, policymakers, and members of civil society with a set of new provisions that they can include in their trade agreements to drive emissions reduction from countries inside and outside of their trade agreements, maintain their ability to compete in an increasingly globalized world, and comply with international trading rules. Ultimately, I seek to demonstrate the untapped potential for leveraging trade agreements to reduce emissions in the midst of an international system that lacks …

Estimating The Economic Value Of Rock Climbing In Smith Rock: An Individual Travel Cost Approach, Cassandra Koefod

All Master's Theses

In this study I estimate the economic value of rock climbing in Smith Rock State Park, Oregon. This area has seen an increase in recreational visits over the years, especially in rock climbing, necessitating economic valuation of the site in order to assist park managers in optimal management of this resource. Given regular conflicts over use of rock climbing areas by a variety of stakeholders (recreational users, habitats, cultural uses, etc.) this study will help in understanding how benefits of recreation is affected when policies limit access to such areas. I collect original survey data on travel to Smith Rock …

Farm To Label: A Critique Of Consumer Activism In The Sustainable Food Movement, Olivia Whitener

Pomona Senior Theses

“Local,” “organic,” “natural,” and “Fairtrade” are just several of the many claims adorning the food products that line grocery store shelves. These promises of environmental sustainability and social responsibility are pillars of the “good food revolution” sweeping the nation as consumers demand alternatives to the products of the industrial food system. Green consumerism, the premise that consumer demand for environmentally sustainable goods will bring about ecologically beneficial outcomes, is at the heart of the sustainable food movement. This thesis takes a critical look at the operation of green consumerism in the food system. It explores the ideology and shortcomings of …

Let's Get Sorted: The Path To Zero Waste At Pomona College, Sara Sherburne

Pomona Senior Theses

This senior thesis in environmental analysis explores the Zero Waste ideal and its practical application to a college campus. Given the growing global trash crisis and its grave environmental, social and economic consequences, the Zero Waste movement argues for a holistic shift from ‘end of pipe’ disposal practices to those that promote the cyclical use of materials, with little-to-no matter ending up in the landfill or incinerator. Cities and colleges around the world have adopted these Zero Waste goals in an effort to function as more sustainable, efficient and moral entities. With a case study of Pomona College, I assess …

Exploring Transit-Based Environmental Injustices In San Gabriel Valley And Greater Los Angeles, Bailey Lai

Pomona Senior Theses

This thesis attempts to disentangle the multilayered interactions between Greater Los Angeles’s history, its built environment, and its inequitable treatment of different peoples, focusing on how transportation in surrounding suburban communities like San Gabriel Valley has developed in relation to the inner city of Los Angeles. Greater Los Angeles contains a long, winding trajectory of transit-based environmental injustices, from the indigenous societies being overtaken by the Spanish missions, to the railroads and streetcars boosting the farmlands and urban growth of Los Angeles, leading into the decline of transit and rise of automobile-oriented suburbia. Within the San Gabriel Valley, the suburban …

Protecting Natural Resources On Agricultural Lands: Producers' Perspectives On The Conservation Stewardship Program In Montana, Mary Ellis

Graduate Student Theses, Dissertations, & Professional Papers

Industrial agricultural production contributes to some of the most significant environmental problems in the United States today. Scientists have identified agricultural production as a primary cause for the decline of native species, soil degradation, and water pollution in the U.S. In response to this crisis, grassroot organizations crafted, and got Congress to pass, the Conservation Stewardship Program (CSP), a federal program aimed to incentivize producers to increase on-farm conservation practices. CSP is designed to serve as a space for producers to gain access to financial and technical support, test out new practices, and provide a platform to discuss best practices …

Addressing Divergent Audiences In Conservation Communication: An Examination Of Land Trust Websites In Northern California, Tova Fleming

Cal Poly Humboldt theses and projects

In a world rich with a diversity of stories and values, successful conservation must not rely on everyone thinking and feeling the same way. Values are the foundation of the cognitive hierarchy of human behavior and are relatively fixed and unlikely to change. As a result, environmental communication that is reliant on a particular set of values may cause polarization around conservation issues. The reasoned action approach offers a way to explore communication techniques that address the cognitive hierarchy of human behavior at its most malleable point, behavioral intentions. Because land trusts work with historically divergent audiences who are often …

Exploring Community Knowledge And Perceptions Of Flooding And Sea-Level Rise In King Salmon, California, Kristina Kunkel

Cal Poly Humboldt theses and projects

The coastal community of King Salmon, California could be at the highest risk of relative sea-level rise on the entire U.S. West Coast. In 2019, the community already experiences severe flooding at least annually and may be regularly inundated as early as 2050. Until this study, there had been no documented effort to reach out to the community to show them future sea-level rise projections, understand the context of life in King Salmon, and listen to their reactions and perceptions. This research utilized a mixed methods grounded theory approach integrating semi-structured interviews with King Salmon stakeholders, qualitative data analysis, public …

Role Of Natural Wetlands In Arsenic Removal From Arsenic-Contaminated Runoff, Vanlop Thathong, Netnapid Tantamsapya, Chatpet Yossapol, Chih-Hsiang Liao, Wanpen Wirojanagud

Applied Environmental Research

This research aims to identify the role of natural wetlands in arsenic (As) removal. Phu Lek wetland in Loei Province, Thailand, was selected as the study area. Monthly samples of water (144), plant (360), and sediment (144) were collected from the wetland for 24 months. As concentration in the surface water at the wetland inlet was 0.85±0.26 mg L-1, and 0.02±0.01 mg L-1 at the wetland outlet. It was observed that the As level in water decreased significantly along its flow path, with an As removal efficiency of 98 %. As concentration in the sediment was 89.53-356.22 mg kg-1 at …

Application Of A Mixed Order Model To Determine The Rate Adsorption Of 1-Nitronaphthalene Onto Activated Carbon, Suntree Rincome

Applied Environmental Research

This study investigated the adsorption kinetics of 1-nitronaphthalene solution (a polycyclic aromatic hydrocarbon, PAH) onto seven different masses of activated carbon. The coefficient of determination (r2) was used to determine the best-fit kinetic model and to confirm agreement between experimental data and the kinetic rate equations. The results indicated that adsorption could be defined with masses of 0.0200 g and 0.0501 g when fitted using a second order rate equation. Adsorption on to masses of 0.1003 g, 0.1203, 0.1501 g, and 0.2001 g was best defined when data were fitted to a pseudo second order rate equation. However, adsorption onto …

Middle To Late Holocene (7200-2900 Cal. Bp) Archaeological Site Formation Processes At Crumps Sink And The Origins Of Anthropogenic Environments In Central Kentucky, Usa, Justin Nels Carlson

Theses and Dissertations--Anthropology

Though some researchers have argued that the Big Barrens grasslands of Kentucky were the product of anthropogenic land clearing practices by Native Americans, heretofore, this hypothesis had not been tested archaeologically. More work was needed to refine chronologies of fire activity in the region, determine the extent to which humans played a role in the process, and integrate these findings with the paleoenvironmental and archaeological record. With these goals in mind, I conducted archaeological and geoarchaeological investigations at Crumps Sink in the Sinkhole Plain of Kentucky. The archaeological record and site formation history of Crumps Sink were compared with environmental …

This professional paper presents an assessment of the most recent project of Schools for Chiapas (SfC), a U.S.-based solidarity organization working in collaboration with the Zapatista autonomous communities in Chiapas, Mexico. It examines the challenges and potentials of SfC’s efforts to implement food forests at 16 autonomous secondary schools. I contextualize this work within a larger conversation amongst food sovereignty activists and scholars around efforts to scale-out the use of agroecology through education. As the organization looks to …

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Antioch University Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …

Mn Food (In)Security: Are Anti-Hunger Interventions In The Twin Cities Perpetuating Food Insecurity And Poverty?, Emma Kiley

Departmental Honors Projects

While anti-hunger organizations across the nation have been doing important work to address this issue, we have yet to see a significant decrease in food insecurity or poverty. This project uses a literature review and interviews with Twin Cities anti-hunger organizations to answer the following questions: How are anti-hunger interventions and the root causes of food insecurity mismatched? And what would it look like if anti-hunger organizations who are heavily engaged in the ‘feeding movement’ shifted their understanding to see food insecurity as a symptom of poverty, rather than an isolated issue? Working through themes of food charity models, privatized …

Just Preservation, Adrian Treves, Francisco J. Santiago-Ávila, William S. Lynn

Animal Sentience

We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate change. We argue that the interests and well-being of non-humans, youth, and future generations of both human and non-human beings (futurity) have too long been ignored in consensus-based, anthropocentric conservation. Consensus-based stakeholder-driven processes disadvantage those absent or without a voice and allow current adult humans and narrow, exploitative interests to dominate decisions about the use of nature over its preservation for futurity of all life. We propose that authentically non-anthropocentric …

Environmental Protection Services And Salvage Law : Emerging Issues In Perspective, Huiru Liu

World Maritime University Ph.D. Dissertations

This dissertation primarily concerns the law and practice of salvage focusing on its environmental dimension which started to evolve since the Torrey Canyon disaster in 1967, which until that time, was the biggest oil spill in maritime history. In the contemporary era of shipping, a major part of salvorial operations has shifted from property preservation to environmental protection. This dissertation centers on the services provided by salvors to prevent or mitigate damage to the environment. This phenomenon is generally referred to as "environmental salvage" which, it is submitted, is an anomaly and a misnomer. It is therefore proposed that the …
