Effects Of Matching Images Of Natural And Built Environments On Delay Discounting: A Systematic Replication Of Berry Et Al. (2014), Elizabeth Fillmore

Theses

Decision making is heavily influenced by the environment around us. Berry et al. (2014, 2015, 2019) showed that viewing images of natural environments during the delay discounting task resulted in lower impulsive choice, as compared to viewing images of built environments or geometric figures. Berry et al. proposed that attentional factors could explain this effect, however, recent attempts to reproduce Berry et al.’s findings in a different laboratory have been unsuccessful (Johnson 2017, 2018, 2019). The present study tested if manipulating the participants’ observing responses towards different types of images (natural, built, and no images) modulates the effect reported by …

Mandhar Smart Application For The Visual Pollution In Muhaisnah-2 Area – Dubai Uae, Hamda Mohamed Alharmoudi

An estimation of 8,000 to 18,000 are actually confirmed cases of Legionnaires' disease per year in the USA. In the UAE, there has been an increase in the number of cases of Legionnaires’ disease which are associated with recent travel to Dubai. Incidents doubled between October 2016 and August 2017. Legionella pneumophila is found …

Eighteen Mile Creek, Allison Nichols

Theses

Eighteen Mile Creek is a body of work consisting of cyanotype chemigrams that explores the space of a Superfund site located in Lockport, New York. The works installed in the gallery are large in scale and abstract. They are created solely through the interactions between photographic chemistry, contaminated water collected from Eighteen Mile Creek, and light. The cyanotypes are bound in contradictions, engaged in a push and pull with the viewer. Ranging in tone from deep blue to harsh yellow, they make visual gestures towards landscapes and topography, but also towards toxicity and warning. Further contradictions exist. While the prints …

Virgil In Virginia: Eighteenth-Century Pastoralism And The Novus Ordo Seclorum, Alley Jordan

Theses

This work examines classical reception in early America. Specifically, it addresses the role of classical ideas on pastoralism in the thought of one of America’s founders, Thomas Jefferson. Jefferson is best known for his role in the forming of United States government, but he was also influential on developing the idea of “America.” As such, his political theory on agrarian republicanism has strong ties to how the classical poets, such as Virgil and Theocritus, likewise thought about the relationship between land and government.

Biomimicry: A Source For Architectural Innovation In Existing Buildings, Thomas Button

Theses

Today designers, manufacturers and industries are seeking to find sustainable solutions to improve design processes and products that will reduce their environmental impacts. However, they often develop architecture in counterproductive ways by investing time and resources into unproven novel solutions. Yet, there are often better solutions, through biomimicry, that identify successful adaptations found in the natural environment and in biology that can serve to better inform design solutions. Through an in depth investigation of biomimicry, several design strategies are identified, and through a selective process, a few select examples are applied to a renovation of an existing headquarters for the …

The Politics Of Environmental Regulations: What Happened To Market Based Regulations?, Eugene Paul Schmittgens Jr

Theses

Market-based rulemaking was first proposed by President George HW Bush and played an integral role in addressing the problem of acid rain in the Clean Air Act Amendments of 1990. Studies indicated that the market-based regulatory regimen was successful in reducing emissions causing acid rain in a cost effective and efficient manner. The program, at the time of its enactment enjoyed wide spread bipartisan support, including the support of over eighty (80) percent of the Republicans voting on the 1990 Amendments. The same market-based approached was proposed in the American Clean Energy and Security Act (ACES). However, unlike the 1990 …

Novel Lc-Ms Methods For The Determination Of Environmental And Food Contaminants Incorporating Analyte Confirmation Using High Resolution Ms, Michael George Cahill

Theses

The contamination of the aquatic environment with pesticides has become an emerging environmental issue because of the potential risk to human health and wildlife. Effluent from wastewater treatment plants (WWTPs) have been identified as an important source of micro­organic contaminants in the environment. The EC have implemented several directives for the control of pesticides in the environment including the 98/83/EEC directive establishing the concentration of pesticide allowed for human consumption, the 2000/60/EC directive set up to monitor priority pollutants that are hazardous substances in the environment and REACH ensuring these substances are registered, controlled, therefore ensuring that the industry is …

Psychological Benefits And Educational Potential Of Physically Immersive Artificial Environment Pedagogy, Dean Ganskop

Theses

Over the last decade, physically immersive artificial environments (PIAEs) have proliferated. These environments afford greater interactivity, which has been shown to increase learner understanding, knowledge retention, and interest in the subject (Bonwell & Eison, 1991, p. 3; Prince, 2004). It would follow, then, that PIAEs would have similar educational benefits. However, little research has been done to prove that such benefits exist. Immersive environments include 2-demensional and 2.5-dimensional on-screen displays, semi-immersive screens, and physically immersive setups, such as CAVE and blue-c (Display Systems: 3D & Advanced, 2008; Gross, n.d.). There are many perceived benefits to immersive environments. At present, their …

Psyche + Physique, Janet Winkie

Theses

Through this thesis I explore how human perceptions are made regarding masculinity and the impact that apparel and environment have on the male psyche and physique. I perceive the function of men's apparel as providing a hinge, or entry point into the male identity, ultimately examining themes such as gender roles, sexuality, social class and age. In this thesis exploration, I intend to examine the male physique and embody it using male and female byproducts, found objects and accessories.

Incorporating themes such as space and place, this practice of assemblage and installation offers the "staging" of male-themed spaces, providing dialogue …

A Vital Environment, Taesung Jeng

Theses

Every day, nature is being used and is also being destroyed through over cutting and overgrazing of forests and grasslands because of the expansion of human numbers. The economic and material demands of growing villages and towns are not the causes but the results of human activity. What is the impact of the careless occupancy of so many of earth's human occupants? Are we turning everything in nature into something human-made and human used? My artworks emphasize how nature as a lay concept is changed by humans' desire for comfort and materialism. In addition, since human creation is another form …

The Influence Of Context On Message-Making And Audience Reception In Graphic Design, Sarah Kirchoff

Theses

The reception of a graphic design solution is greatly affected by the environment in which it is viewed: the space around it, and how it is approached and accessed. Obviously, the designer cannot control the specific life experiences that shape a viewer's personal response, or how that viewer may be situated in a broader, cultural context. Designers often have at least some degree of control over contextual factors that contribute to the message-making potential of a graphic design solution, as well as the form the solution takes, and how it is presented to an audience. When carefully constructed, content, application, …

A Global Sensitivity Analysis Of Photochemical Models Used For Predicting Tropospheric Ozone, Daniel Wimer

Theses

The Clean Air Act requires the use of complex photochemical models to predict future ozone concentrations and the impact of current and future regulations. In many instances uncertainty in the data input parameters used to operate these models results in uncertainty in the prediction of future air quality. The degree of this uncertainty is often greater than the degreee of air quality improvements proposed by regulations. This study evaluates the sensitivity of a photochemical model to predict future ozone air quality with respect to the uncertainty of several critical input parameters. These parameters are: Transported ozone (ozone aloft) Biogenic emissions …

Making A Business Case For Integrating Multidimensional Sustainability In The Pharmaceutical Industry, Thea Jung

Theses

To grow their bottom lines, companies invest in business value drivers. This thesis examined whether multidimensional sustainability performance could be one of those drivers in the pharmaceutical industry. There are currently very few (if any) mandatory requirements for integrating multidimensional sustainability. Nor are there standardized methods of integrating, measuring, or communicating multidimensional sustainability. This thesis reviewed, compared, and contrasted (also known as benchmarking) voluntary sustainability initiatives and pharmaceutical company sustainability initiatives. The results were as follows: 1) the concept of multidimensional sustainability is generally understood; 2) integrating multidimensional sustainability is the morally and ethically correct action for pharmaceutical companies to …
