Natural Economy in an Unnatural World

My research examines the premise that global climate change and ever-increasing inequality represent the “coming home to roost” of massive long-term externalized costs resulting from the unnatural distortion of the global economy by the effects of unregulated predatory and racist capitalism. The future costs and burdens of global climate change will not be shared equally or equitably. My research considers the likelihood of a shift in the landscape of local economy and markets toward a new post-capitalist reality as the natural market forces of localized production and community values transcend the current unnatural market distortions of a global economy. Using a Cultural Studies and Critical Theory framework of analysis, I research the question through the lens of four main models of community development: Immigrant Communities, New \u27Green\u27 Sustainable Economy, Social Services/Nonprofit Efforts, and Business Development & Entrepreneurial Initiatives to examine core universal elements of community “spirit” and self-sustaining systems that act as a mechanism of binding agency with the formation process. These new systems of self-sustaining natural economy will rebalance the shape and daily life of communities economically, socially, and spiritually as systems of localized economy increasingly emerge to ameliorate the failures of consumer driven neoliberal globalization and massively scaled unregulated capitalism. People will find renewed purpose, meaning and fulfillment in their lives through activity that contains the intrinsic value and well-being that is often missed in today\u27s modern world

Effect Assessment of TiO2 Nanoparticles Exposure on Medicago by Monitoring Morphophysiology

In recent years titanium dioxide nanoparticles (TiO2NPs) have been ingredients in everything from paints to cosmetics, and even in some kinds of food. This growth in use has resulted in a substantial increase in the amount of titanium released into the environment, which could have detrimental effects on nearby plant and animal life. Currently, the number of studies conducted on the effects of TiO2NPs is quite small, especially when it comes to edible crops. Because of this lack of research data, this study has been designed to assess the effect of TiO2 NPs exposure on growth and physiology of Medicago truncatula. This plant was chosen because each species has a unique reaction to nanoparticles, and it also an important feed crop for the cattle industry. The plants were grown in Turface MVP® soil that had been treated with 250, 500, 1000, and 2000 parts per million of TiO2NPs for two weeks and then examined for changes in biomass, metal ion concentrations, and gene expression related to antioxidant and photosynthesis. The results varied between the different experiments, but in general the dry weight showed a decrease in mass from the control to the treated soils. The metal nutrients estimation, which recorded a spike in titanium content in the 500 and 1000 PPM samples, showed a correlation between the titanium and important building blocks such as phosphorus, and a majority of the genes tested showed a spike in shoot expression at 250 PPM relative to control mark followed by a decline with the other samples. Altogether, it appears that TiO2 NPs adversely affect the growth of Medicago at high concentration exposure

The Battle of Gentrification vs. Centrification: The Role of the Nonprofit Sector and the Hilltop of Tacoma

Gentrification continues to be a central concern for residents of formerly under-served and under-resourced areas of many cities that begin to experience economic development. For some stakeholders Gentrification represents a boon of economic opportunity, growth, development, new tax base and profits. Yet, often-times Gentrification can have a much different meaning and outcome for existing residents of the area. My research examines how the negative effects of Gentrification— that center in displacement, loss of community identity, and economic development that often does not benefit existing community (directly or indirectly)—can be mitigated by nonprofit Community Based Organizations (CBOs) and local government. This collaborative effort of coordinated community response to Gentrification is reflected in the term Centrification. My research looks at how local governments are working with community nonprofit organizations to successfully serve what are often two conflicting forces—economic development and community security and stabilization — that usually arrive together with the onset of Gentrification. I then examine the premise of Centrification through the role and practices of CBOs, nonprofits, and advocacy groups in the Tacoma area that work to build community engagement, raise-up and prioritize efforts to avoid displacement for existing residents, and champion their opportunities and value in the face of Gentrification. My research reviews the historical policy and practices of several decades that has caused a recent relocation of 35% of the African American population out of the Hilltop area. It also reviews the more recent efforts by the City of Tacoma to address the potential negative impacts of Gentrification and examine how that work has been implemented in partnership with community Nonprofits, CBO’s, and other community based private/public groups

Testing and Analysis of an Alternative Connection Method in Closed Panel Timber Frame Domestic Construction

Construction practices continue to evolve in tandem with the requirements for more energy efficient buildings, materials and construction methods. This steady and progressive move towards the development of the industry and its products comes, not in leaps and bounds, but in incremental advances across all areas of construction. The research detailed in this project is one such advancement. Timber frame construction has been in existence for centuries and its tried and tested methods have been utilised worldwide in both domestic and industrial building. In recent times, standard open panel timber frame construction has been enhanced by the development of closed panel timber frame construction. This method of timber frame construction permits more of the structure to be pre-fabricated in a factory setting resulting in less material exposure to weather conditions during construction. This research project examines the development of a new connection method in the assembly of closed panel timber frame walls which allows entire wall-panels to be pre-fabricated before deployment to site. The new connection method is achieved using tapered aluminium alloy fasteners pre-installed on each wall panel before on-site assembly. With the aid of a timber frame construction company, an action research process was put in place to critically assess and develop the application of the connection method across four live construction projects. Achieving a satisfactory connection detail then allowed for more considered structural and thermal testing to take place. A Thermal assessment of the details was carried out using both thermograhic camera surveys and thermal simulation software. Both compressive and lateral force structural tests were carried out on scale model wall panels in order to accurately compare the new connection method with that of a traditional screw-fixed connection detail. The results obtained from both forms of testing support and give impetus to the use of the new connection detail in preference to existing practices for future timber framed construction
