As we move toward energy independence and more ambitious clean energy goals, solar energy research must push the efficiency limits of traditional energy generation systems. Increases in efficiency can be achieved by increasing the hot temperature of the power cycle. Recent research demonstrates the potential for increased efficiency and a vastly smaller component size when supercritical carbon dioxide Brayton power cycles are used. Concentrated solar and nuclear heat sources are capable of achieving the high working fluid temperatures needed for significant efficiency gains. This NSF EPSCoR funded, experimental research system is designed to exploit the uniquely immense solar irradiance of …
Employee Perceptions Of Organizational Corporate Responsibility And Their Effect On Employee Organizational Commitment, Lisa R. Davis

The debate over whether organizations play a part in society beyond economic profit has been a major focus of research in corporate social responsibility (CSR). These debates have been mainly looked at from the macro (societal) or the meso (institutional) level. Very little research has been done on the role of the firm and looking at CSR from the micro (individual) level. Questions regarding the role of work for employees, securing economic benefits or making a difference in the world, would vary greatly depending on the individual and the importance they place on these areas in their own lives. Scholars …
Influencing Hawai‘I Hotel Patrons To Use Reef-Safe Sunscreens, Rochelle Good
Influencing Hawai‘I Hotel Patrons To Use Reef-Safe Sunscreens, Rochelle Good
UNLV Theses, Dissertations, Professional Papers, and Capstones
The health of Hawaiian coral reefs is threatened by pollution from common sunscreen ingredients such as oxybenzone. Hawai‘i hotel patrons using sunscreens with harmful ingredients contaminate coral reefs when these products wash off while swimming or bathing. Reef-safe sunscreens are alternative sunscreens that provide effective sun protection while averting damage to coral reefs. The purpose of this research was to determine the dominant factors leading to the pro-environmental behavior of using reef-safe sunscreen and identify practices that Hawai‘i hotel operators could implement to influence patrons to engage in this behavior. This research applied an integrative conceptual framework to model pro-environmental …

ABSTRACT
HUMAN THERMAL COMFORT IN TRANSITION SPACES
Objective: To evaluate and identify the relationship between personal factors and the climatic conditions that influence the human thermal comfort in transition spaces and suggest solutions for adaptation of the built environment, that would encourage active and healthy living in the tourist as well as local community.
Background:
By 2050, there is a prediction that two-thirds of the world population will be living in urban areas, which would add more than 2.5 billion people living in cities (Melnikov et al., 2017). Since Las Vegas is one of the fastest growing cities in Nevada, …

This research evaluates the effects of varying thermal properties of windows in
residential energy use for the moderate altitude and 36'N latitude climate of southern
Nevada, which has a distinct cooling season. A selection of windows across different
shading conditions and total window areas were studied using BEopt energy simulation.
Findings demonstrate that for the specific climate, latitude, and altitude of Las Vegas,
Nevada, the most expensive “high performance” windows are not always the best
option in terms of total site energy use, and can be outperformed by properly shaded
less advanced windows. Under certain conditions, shading was found to …
