Improving Indoor Air Quality Through Botanical Air Filtration In Energy Efficient Residences, Daniel William Newkirk

Open Access Theses

According to the U.S. EPA, the average American spends 90% of their time indoors where pollutants are two to five times more prevalent than outside. The consequences of these pollutants are estimated to cost the U.S. 125 billion dollars in lost health and productivity. Background literature suggests botanical air filtration may be able to solve this problem by leveraging the natural ability of plants to purify indoor air. By improving indoor air quality, energy consumption can also be reduced by bringing in less outside air to dilute contaminants within the space. A botanical air filter, called the Biowall, was designed …

Determinants Of Energy Efficiency Across Countries, Guolin Yao

Open Access Theses

With economic development, environmental concerns become more important. Economies cannot be developed without energy consumption, which is the major source of greenhouse gas emissions. Higher energy efficiency is one means of reducing emissions, but what determines energy efficiency?

In this research we attempt to find answers to this question by using cross-sectional country data; that is, we examine a wide range of possible determinants of energy efficiency at the country level in an attempt to find the most important causal factors.

Energizing Europe: The Geopolitics Of Energy Security And Energy Diversification In The European Union, Gabriel Alfredo Uribe

Independent Study Project (ISP) Collection

Europe has always had an interesting relationship with Russia, be it social, political, or economic. From the days of the Cold War, when there was the ideological battle of communism versus capitalism, with the alliance of NATO representing a front against the Iron Curtain, certain remnants of this dynamic have still survived. Russia has not always had the best of relations with the European Union (EU), which has not made it easy for the EU to have fully functioning foreign relations with them. This is problematic specifically because of the importance that Russia has on EU energy security, as it …

Organizational Fields, Transnational Business Governance Interactions And The Diffusion Of Csr, Melanie Coni-Zimmer

Transnational Business Governance Interactions Working Papers

The paper analyzes the process of global diffusion of Corporate Social Responsibility (CSR) in the oil industry and how interactions between different actors have contributed to this outcome. It starts from the empirical puzzle that CSR has spread globally among transnational corporations since the mid 1990s (diffusion of CSR as a dependent variable). To explain this phenomenon, the paper presents a theoretical argument based on insights from sociological neo-institutionalism. It uses the concept of organizational fields as social spaces where organizations interact with one another. The structuration of an organizational field leads to processes of homogenization among the organizations belonging …
