Graffiti Gallery, Mike Delvalle

Architecture Theses and Projects

This project is an architectural exploration of the ability of architecture to enhance the lives of those belonging to stigmatized subcultures, in this case graffiti artists, Skateboarders, BMXers, and Rollerbladers. To do this there is a focus on achieving a spatial justice for these social groups by creating public space that is in fact public, uninhibited by the processes of inclusion and exclusion that plague nearly every public space. More importantly than achieving spatial justice, however, is creating a societal awareness of the positive attributes of these subcultures. After all, it is society that has control over how public spaces …

Invention Center: A Building Of Inventions, Jonathan T. Archbald

Architecture Theses and Projects

In today’s world, the word sustainable often goes hand in hand with design. As a recent trend the LEED standards are used as a way to “prove” a building’s commitment to being sustainable. LEED however is only the tip of the sustainable iceberg of what design can actually be. The term Sustainable has to be linked with the term efficient. Sustainability is more than the design and construction of a project. It has to be involved with all aspects of a project’s life.

Creating Social Networks: Resettlement Center For Burmese Refugees, Kelly Lynne Clarke

Architecture Theses and Projects

The refugee resettlement program in the United States must encourage both the formation of refugee communities and integra­tion within the larger community. I propose a multiuse building to strengthen refugee communities [bonding social networks] and connect refugees to the larger community [bridging social networks]. Both of these connections are essential for refugees to become integrated in a community. The building will be run by Lutheran Social Services who currently assists in the resettle­ment of refugees in the Springfield, Massachusetts area, with assistance in funding from the Wilson-Fish Discretionary Grant Program which provides financial support for alternative models of resettlement.

Sacred Stones For Sacred Structures: An Examination Of Patterns In The Temples And Twin Complexes At Tikal And Palenque, Meredith Mae Hild

Honors Program Theses

Extensive work in uncovering and reconstructing Classic Maya temples has been completed while the importance of Maya studies has increased during the past centuries. Little has been done, however, in the interpretation of certain Maya structures within the context of Maya thought. That context includes an understanding of the Maya interpretation of their place within the cosmos, an aspect of Maya culture that dictated every individual's daily actions. Researchers have tended to focus on architectural analyses that describe the dimensions and building materials of temples and other monumental structures. This leads to interpretations that are lacking in cultural significance. While …

Influencing Factors Behind Urban Sprawl In The United States, Charles N. Cowell

Honors Program Theses

Urban sprawl concerns planners, urban economists, and city governments because of several negative side effects associated with it. Urban sprawl can be defined many ways, but the Merriam-Webster Dictionary states it as “the spreading of urban developments (as houses and shopping centers) on undeveloped land near a city.” Deprivation of the environment, automobile reliance, inner city poverty, and even obesity are suggested to be linked to sprawl. In order to address urban sprawl effectively, its causes need to be identified. Ordinary Least Squares (OLS) regression analysis will be used to show factors that may contribute to urban sprawl in the …

Using Case Studies To Characterize The Broader Meaning Of Engineering Design For Today’S Student, Pamalee A. Brady, John W. Lawson

Architectural Engineering

Numerous organizations have undertaken the task of envisioning the education required to meet the engineering demands of the future. The ABET study EC2000, ASCE’s Civil Engineering Body of Knowledge and Body of Knowledge 2 and the National Academy of Engineering have documented the need to change engineering education from its historical focus on technical content knowledge to include greater emphasis on professional issues and to integrate engineering practice into education. To this end teaching methods such as project-based learning, and the use of case studies are being explored to address these broader learning outcomes. Case studies in particular facilitate telling …

 Ontario,
 California, Ashley L. Mccoy

Pomona Senior Theses

Food insecurity is defined as “a household‐level economic and social condition of limited or uncertain access to adequate food” (USDA Economic Research Service 2009). Low‐income households tend to be food insecure for many reasons. The first and most obvious would be the access to monetary resources. If a household does not have a sufficient income, it is difficult to keep an adequate amount of food for all household members at all times. Another reason would be that many low‐income households cannot afford a car and/or do not have easy access to public transportation or reliable private transportation.

Public Investment And Economic Growth In El Paso, Azucena Gonzalez Monzon

An Error Correction model and a Vector Error Correction model are utilized to discover short-run and long-run impacts from public capital stock on the growth of this particular economy. The Vector Autoregressive model is used to determine causality amongst the variables and to determine the structure of this economy. This research finds that public infrastructure growth actually follows economic growth and private …

Methodology To Convert A Transportation Planning Origin-Destination Matrix Into A Microscopic Traffic Simulation Origin-Destination Matrix, Jose Osiris Vidana-Bencomo

Open Access Theses & Dissertations

Microscopic traffic simulation (MTS) is a cost-effective approach for the evaluation of traffic conditions in urban highways networks. In MTS models, traffic demand that is entered into the network is specified by one or several Origin-Destination (O-D) matrices. A major challenge in the application of MTS for large urban networks is the specification of the O-D matrices. This dissertation proposes a methodology that may be used to transform a O-D matrix from a transportation planning model (which is based on Traffic Analysis Zone, or TAZ, and is readily available) into a O-D matrix for a MTS model (which is traffic …

Dormant Ethnobotany: A Case Study Of Decline In Regional Plant Knowledge In The Bull Run Mountains Of Virginia, Susan Rene Leopold

Antioch University Dissertations & Theses

This dissertation introduces and applies the concept of dormant ethnobotany, a concept that helps explain the socio-economic, cultural and ecological aspects and implications of the transition away from active use of ethnobotanical knowledge and the factors that may lead to its re-emergence. Dormant ethnobotany is the study of relationships between people and plants that are inactive, but nonetheless still alive in memories, the historic record, and folklore and thereby capable of reemergence in support of the transition to a more sustainable society. The dissertation extends the field of ethnobotany from its current roots in the dynamic ethnobotany of indigenous peoples. …

High-Strength Selfconsolidating Concrete Girders Subjected To Elevated Compressive Fiber Stresses, Part 2: Structural Behavior, Jared E. Brewe, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The design of prestressed concrete members is restricted by the requirement that the extreme compressive fiber stress at midspan be less than 60% of the concrete compressive strength at release of prestressing. the purported purpose of this limit is to provide serviceability performance, but it places unnecessary limits on the capability of the materials. for this research program, six prestressed concrete girders were produced with high-strength, self-consolidating concrete and subjected to elevated compressive fiber stress levels ranging from 65% to 84% of initial concrete compressive strength at release of prestressing. Part 1 of this series analyzed time-dependent prestress losses and …
