Managing of Vulnerabilities and analyzing them is directly related to the first approach. Developing of methodologies and models to predict the behavior of attackers is related to the second approach. Both these approaches are inseparably interconnected. Our effort in this study mainly focuses on developing useful ...


Pollen Forecasting In Sarasota, Florida, Daniel J. Gessman Jun 2017

Pollen Forecasting In Sarasota, Florida, Daniel J. Gessman

Graduate Theses and Dissertations

Current predictions of pollen levels rely strictly on historical Averages, regardless of environmental factors that might affect the timing of pollen release by different plants. For this thesis, the goal was to develop a statistical model that will accurately forecast pollen levels by correlating those daily counts to atmospheric and meteorological conditions. This project used ARIMA modeling on IBM’s SPSS Statistics 24 of daily pollen count information for multiple allergenic pollens in the Sarasota County, Florida area over a 11-year period. The pollen species in question for this project are oak and cypress trees, grass, and ragweed pollens; and ...

#Notiowanice: Guerrilla Design Tactics And Addressing Nitrate Pollution, Heather V. Sumners-Purdy Jan 2017

#Notiowanice: Guerrilla Design Tactics And Addressing Nitrate Pollution, Heather V. Sumners-Purdy

Graduate Theses and Dissertations

Calling attention to the issue of nitrate pollution in Iowa’s waterways as a result of current agricultural practices, my goal was to initiate a dialogue on social media prompted by guerrilla tactics. The issue of nitrate pollution has been steadily increasing over the past decade as a result of Iowa’s lack of environmental mandates to maintain and monitor nitrate leeching from the soil into the watersheds. In 2015, this issue initiated a lawsuit by the Des Moines Water Works against three northern farming counties, citing runoff into ditches that feed into the Raccoon River as source points of ...


"If You Have Money, You Have Water": Intersectional Influences On Women’S Participation In Irrigation Management In Batken, Kyrgyzstan, Rebecca E. Nixon Jan 2017

"If You Have Money, You Have Water": Intersectional Influences On Women’S Participation In Irrigation Management In Batken, Kyrgyzstan, Rebecca E. Nixon

Graduate Theses and Dissertations

Participatory processes have been widely promoted within the field of natural resource management as a method to support efficient resource use. As women are often key stakeholders in natural resource use, the importance of their inclusion in these initiatives has also been stressed. Specifically, research has shown that women’s participation positively impacts outcomes of development initiatives and can transform gendered hierarchies by empowering women in community decision making. However, participatory initiatives are not necessarily inclusive; rather, it has been shown that these processes can exacerbate existing inequalities and specifically, that women can be excluded from participation.

In Kyrgyzstan, participation ...


Rural Revitalization Throughout The Midwest: Preserving Our Past To Create A Sustainable Future, Mackenzie Rebekka Waddell Jan 2017

Rural Revitalization Throughout The Midwest: Preserving Our Past To Create A Sustainable Future, Mackenzie Rebekka Waddell

Graduate Theses and Dissertations

ABSTRACT

Rural revitalization has grown in popularity in recent years. Throughout the Midwest*, communities have adopted this practice in order to preserve their heritage. The benefits of this practice are social, cultural, economic, agricultural, environmental, and historical in nature. When restoring a community’s commercial district and subsequent residential neighborhoods, it is shown that property values as well as tourism increase. Rural revitalization also leads to a decrease in suburban growth thus preserving valued farmland. A community can experience all these benefits by working to preserve its architectural and historical integrity. Proof of this statement can be witnessed in communities ...


Cloud Composition Technologies In Multimodal Composition Program Documents, Philippe Peter Meister Jan 2017

Cloud Composition Technologies In Multimodal Composition Program Documents, Philippe Peter Meister

Graduate Theses and Dissertations

Writing programs at numerous universities—including the Georgia Institute of Technology, Iowa State University, Miami University of Ohio, Virginia Tech, and Purdue University—are incorporating more learning about multimodal communication into their curricula, including written, oral, visual, and electronic communication (WOVE). Within WOVE, electronic technologies enable students to produce, distribute, and consume written, visual, oral, and electronic communication (Ong 1982; Bush 1945; Eisenstein 1979, Lauer 2009, 2014). Integrating cloud technologies into writing programs may be difficult because it requires ongoing training, support, and maintenance, but it may be worthwhile because it helps produce a writing culture mediated by these technologies ...


Material Expertise: Applying Object-Oriented Rhetoric In Marine Policy, Zachary Parke Dixon Jul 2016

Material Expertise: Applying Object-Oriented Rhetoric In Marine Policy, Zachary Parke Dixon

Graduate Theses and Dissertations

This dissertation applies object-oriented rhetorics and posthuman philosophies to environmental policy deliberation in order to help bridge gaps between policy makers, scientists, and citizens. For environmental policy scholars the non-credentialed expertise of local, or indigenous stakeholders is valued as possessing technical, objective merit that can improve the development and implementation of environmental policies. However, the utilization of stakeholder expertise in environmental policy faces serious challenges in terms of finding common grounds for communication within complex techno-social systems, of overcoming deep cultural differences and perceptions, and grave ethical issues of access and power. This dissertation develops two case studies of marine ...


Digital Integration, Jacob C. Boccio Jun 2016

Digital Integration, Jacob C. Boccio

Graduate Theses and Dissertations

Artificial intelligence is an emerging technology; something far beyond smartphones, cloud integration, or surgical microchip implantation. Utilizing the work of Ray Kurzweil, Nick Bostrom, and Steven Shaviro, this thesis investigates technology and artificial intelligence through the lens of the cinema. It does this by mapping contemporary concepts and the imagined worlds in film as an intersection of reality and fiction that examines issues of individual identity and alienation. I look at a non-linear timeline of films involving machine advancement, machine intelligence, and stages of post-human development; Elysium (2013) and Surrogates (2009) are about technology as an extension of the self ...


Surrogate-Based Design Optimization Of Dual-Rotor Wind Turbines Using Steady Rans Equations, Andrew Scott Thelen Jan 2016

Surrogate-Based Design Optimization Of Dual-Rotor Wind Turbines Using Steady Rans Equations, Andrew Scott Thelen

Graduate Theses and Dissertations

Dual-rotor wind turbines (DRWT) may offer better energy efficiency over their single-rotor counterparts in isolated and in windfarm operation. The design and analysis of DRWT requires, among other, the use of computational fluid dynamics models. Depending on their formulation, these models can be computationally expensive. Numerous simulations are typically required during the design process, which may render the overall computational cost to be prohibitive. This thesis investigates and compares several optimization techniques for the design of DRWTs. In particular, the DRWT fluid flow is solved using the Reynolds-Averaged Navier-Stokes equations with a two-equation turbulence model on an axisymmetric mesh, while ...


Developing Interactive Learning For Environmental Issues, Meriesa C. Elliott Jan 2016

Developing Interactive Learning For Environmental Issues, Meriesa C. Elliott

Graduate Theses and Dissertations

The environment is being negatively affected by the behavior of human beings. Climate change, while a natural occurrence, is happening at an unnatural pace, sped up by human actions. Even with these things in mind, it seems an impossible task to get people to move toward positive environmental impacts. While many people are aware of environmental issues, they don’t fully understand what actions are contributing to the problems, what alternative options they have, or how they can help alleviate the problem. With that in mind, I examine how effective interactive design can be at creating a learning environment by ...

Place-Based Communities And Neoliberalism: A Study Of The Artisanal Fishing Community Of Chorrillos, Peru, Héctor Andrés Bombiella Medina Jan 2016

Place-Based Communities And Neoliberalism: A Study Of The Artisanal Fishing Community Of Chorrillos, Peru, Héctor Andrés Bombiella Medina

Graduate Theses and Dissertations

This dissertation is about artisanal fishers in Chorrillos, a small bay near the southern edge of Lima, Peru, and how they use place as an instrument to defend their access to fishing resources on Peru's central coast. The context of this research work includes global neoliberal influences on the Peruvian state and the negotiation of global and local economics, politics, and social issues. Over the last decade, depletion in fish stocks has led to tensions between industrial and artisanal fishers, and demands from the industrial sector to reduce Peruvian state protections for artisanal fishers. Not only are Chorrillos's ...


Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan Jan 2016

Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan

Graduate Theses and Dissertations

We study the problem of detecting non - termination in multi - threaded programs due to unwanted race conditions. We claim that the cause of non-termination can be attributed to the presence of at least two loops in two different threads, where the valuations of the loop controlling parameters are inter-dependent, i.e., value of one parameter in one thread depends on the execution sequence in the other thread and vice versa. In this thesis, we propose a testing based technique to analyze finite execution sequences and infer the likelihood of non-termination scenarios. Our technique is a light weight, flexible testing based ...

A Comparative Analysis Of Portable X-Ray Fluorescence Spectrometry And Stable Isotopes In Assessing Ancient Coastal Peruvian Diets, Theresa Jane Gilbertson

Graduate Theses and Dissertations

This dissertation explores a cross-cultural analysis of the dietary signatures of four coastal cultures of prehistoric Peru. A combination of elemental analysis based on portable x-ray fluorescence spectrometry (pXRF), testing trace elements presented in 209 individuals’ skulls representing the Nazca (38), Cañete (33), Lima (40), and Moche (98) valleys and/or cultures of the first millennium AD, is weighed in conjunction with isotope ratio mass spectrometry (IRMS) to analyze human bone collagen and bone apatite derived from a portion of the individuals represented in the Nazca, Cañete, and Lima cranial samples.

Evidence from the results of both tests are weighed ...


Cather And The Turner Thesis: Reimagining America's Open Frontier, Tonya Ann Tienter Jan 2015

Cather And The Turner Thesis: Reimagining America's Open Frontier, Tonya Ann Tienter

Graduate Theses and Dissertations

Willa Cather often earns attention from environmental literary scholars for her beatific and nostalgic depiction of "the frontier," though in this ecocritical study, I argue that Cather presents a unique, multi-faceted evolution of America's frontier and claims it, once again, as a physical place that deserves salvaging. From 1913-1925, Cather worked within Frederick Jackson Turner's frontier rhetoric, yet she moved America's frontier from a physical landscape of the past to a frontier-of-war in France and finally into the home. With O Pioneers!, Cather offers a nostalgic view of life in Nebraska, though she rejects Turner's creation ...


Call It Eden: A Novel, Stefanie Brook Trout Jan 2015

Call It Eden: A Novel, Stefanie Brook Trout

Graduate Theses and Dissertations

This historical novel is a book-within-a-book. Eden: A Genesis--A History of the Carson Family is framed as a work of nonfiction by the fictional character Lee Rickels. The collection of artifacts assembled by Rickels includes interviews, journal entries, and news clippings covering a fifty-year period following the family line of Frank and Ada Carson, who met in 1920s Chicago and escaped to Eden, an unsettled island in Lake Huron where they built their own community. The false documents are bookended by a foreword and afterword by Rickels and footnoted throughout, creating a double narrative on the subjectivity of history. The ...


Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre Jan 2015

Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre

Graduate Theses and Dissertations

Agency is a foundational and ongoing concern for the field of Rhetoric and Composition. Long thought to be a product and possession of human action, rhetorical agency represents the most obvious connection between the educational and theoretical work of the field and the civic project of liberal arts and humanities education. Existing theories of anthropocentric rhetorical agency are insufficient, however, to account for the complex technological work of digitally enmeshed networks of humans and nonhumans. To better account for these complex networks, this project argues for the introduction of new materialist theories of distributed agency into conversations about agency within ...


It's About Time: Dynamics Of Inflationary Cosmology As The Source Of The Asymmetry Of Time, Emre Keskin May 2014

It's About Time: Dynamics Of Inflationary Cosmology As The Source Of The Asymmetry Of Time, Emre Keskin

Graduate Theses and Dissertations

This project is about the asymmetry of time. The main source of discontent for physicists and philosophers alike is that even though in every physical theory we developed and/or discovered for explaining how the universe functions, the laws are time reversal invariant; there seems to be a very genuine asymmetry between the past and the future. The aim of this project is to examine several attempts to solve this friction between the laws of physics and the asymmetry and provide a new proposal that makes use of modern cosmology. In the recent history of physics and in contemporary philosophy ...

Public Perception Of Sustainable Interior Design Practices In Residential Settings, Stephanie Paula Wingate Jan 2014

Public Perception Of Sustainable Interior Design Practices In Residential Settings, Stephanie Paula Wingate

Graduate Theses and Dissertations

To better understand public perception of sustainable interior design practices in residential settings, two groups of seventy-five home improvement show attendees responded to a twenty question survey. The survey comprised of questions aimed at establishing attitudes about ecology, factors that influence sustainable design preferences and demographics. The ecology section utilized an abridged version of the New Ecological Paradigm Scale (Dunlap et al. Journal of Environmental Education, 9:10, 2000), which is a survey utilized to predict environmental world views. Items in the sustainable design section were chosen to reflect participants' opinions about sustainable design features in the home, along with ...


Nobile: Design And Evaluation Of A Persuasive Technology Application For Social Behavior Change, Batzaya Batsaikhan Jan 2014

Nobile: Design And Evaluation Of A Persuasive Technology Application For Social Behavior Change, Batzaya Batsaikhan

Graduate Theses and Dissertations

Modern society is becoming increasingly connected and more and more technology-enabled. Communication technology is as portable as ever, thus rapidly proliferating, and not surprisingly, many carry at least one or more communication technologies, such as smartphones and tablets, with them on a daily basis, giving the means of constant connection. As a result, this constant connectivity has been discreetly disrupting not only how communication occurs between people but also lives. People come together but barely speak to each other. Rather, they rely on technology, for instance, smartphones, for companionship, and this may have negative consequences on one's social life ...
