Investigation Of A Water Desalination Method Via A Humidification-Dehumidification Process Using Hvac Technology, Juan Antonio Cornejo

Open Access Theses & Dissertations

Potable water is becoming a scarce resource in many arid regions of the world. An experimental unit was designed and constructed to examine and characterize the production capabilities of a humidification-dehumidification (HDH) desalination process. An HDH cycle offers a viable, technologically light, alternative for producing fresh water from brackish water because the low relative humidity air is infused with water vapor through evaporation by means of conventional heating, ventilation and air conditioning (HVAC) components. The evaporation process effectively separates salts and suspended solids from the brackish feed-water. Desalinated water is subsequently recovered by extracting the water vapor from the moist …

Cover Crop Mixtures For The Western Corn Belt: Opportunities For Increased Productivity And Stability, Samuel E. Wortman, Charles A. Francis, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

Achieving agronomic and environmental benefits associated with cover crops oft en depends on reliable establishment of a highly productive cover crop community. The objective of this study was to determine if cover crop mixtures can increase productivity and stability compared to single species cover crops, and to identify those components most active in contributing to or detracting from mixture productivity. A rainfed field experiment was conducted near Mead, Nebraska, United States, in 2010 and 2011. Eight individual cover crop species (in either the Brassicaceae [mustard] or Fabaceae [legume] family) and four mixtures of these species (two, four, six, and eight …

The Role Of Communication In Sustainable Development, Tracy Ging

Communication & Leadership Dissertations and Theses

As population growth accelerates, there are new strains on agricultural production and a growing consideration for sustainable development. Within the field of sustainable development, collective action models or collaborative processes have been favored as a way to engage multiple stakeholders and address complex issues. Collective and collaborative action studies have emphasized communication, but little specifics have been offered about the role of communication. Using a qualitative interview process and ethnographic analysis, this case study explores the role of communication in collaboration. In addition to developing insights into specific communication practices, the research reveals a significant emphasis on mutually supportive relationships …

Using Participatory Scenarios To Stimulate Social Learning For Collaborative Sustainable Development, Kris A. Johnson, Genya Dana, Nicholas R. Jordan, Kathy J. Draeger, Anne Kapuscinski

Dartmouth Scholarship

Interdependent human and biophysical systems are highly complex and behave in unpredictable and uncontrollable ways. Social and ecological challenges that emerge from this complexity often defy straightforward solutions, and efforts to address these problems will require not only scientific and technological capabilities but also learning and adaptation. Scenarios are a useful tool for grappling with the uncertainty and complexity of social-ecological challenges because they enable participants to build adaptive capacity through the contemplation of multiple future possibilities. Furthermore, scenarios provide a platform for social learning, which is critical to acting in the face of uncertain, complex, and conflict-laden problems. We …

A Systems Approach To Ecological Economic Models Developed Progressively In Three Interwoven Articles, Takuro Uehara

Dissertations and Theses

My dissertation develops and analyzes ecological economic models to study the complex dynamics of an ecological economic system (EES) and investigate various conditions and measures which can sustain a developing economy over the long term in view of resilience and sustainability. Because of the intrinsic complexity of the system, I take a systems approach, using economics as the foundation for the basic structure of an ecological economic model, and system dynamics as the method to build and analyze such a complex ecological economic model. Throughout my dissertation, the model developed by Brander and Taylor (1998) is adopted as a baseline …

An Integral Theory Perspective On The Firm, Nancy E. Landrum, Carolyn L. Gardner

School of Environmental Sustainability: Faculty Publications and Other Works

We propose that Ken Wilber’s (2000) integral theory can serve as a new paradigm by which to view the organization and present a broader view of the roles and responsibilities of business. Through an integral theory of the firm, we see individual desires, capabilities and limitations, economic profit and humanitarian interest working in synergy to maximize firm performance. This holistic approach is innovative and is presented as a way to redefine the existence, boundaries, and organization of the firm and to show how organizations can become more ecologically sustainable, socially responsible, and economically competitive. An integral theory of the firm …

Corporate Accountability: A Path-Goal Perspective, Nancy E. Landrum, Cynthia M. Daily

School of Environmental Sustainability: Faculty Publications and Other Works

Corporations are increasingly seeking corporate accountability. There have been a growing number of principles, standards, measurement tools, and guides for reporting, stakeholder engagement, and assurance to aid corporations; many of which are discussed here. Yet corporations are faced with a confusing array of competing protocols and a complex challenge in defining how to navigate the process to improve accountability. Path-goal theory offers a perspective which allows us to present a simplified 3-step path to guide corporations. However, path-goal theory also reveals problems inherent in the current approach, namely, an ambiguous situational context and lack of leadership that is directive, task-oriented, …

Global Csr And Photographic Credibility: Exploring How International Companies Portray Efforts Through Photographs In Csr Reports, Janel Lynn Norton

USF Tampa Graduate Theses and Dissertations

We are living in the age of the visual. Imagery is an important element in constructing and deriving meaning through symbols, colors, and context. Images may hold persuasive power, be used as evidence, or simply provide a moment of beauty. Organizations rely on photographs to help them convey an image to their stakeholders within annual reports. Telling an organizations' story through photographs has become an intrinsic part of their efforts to convey sustainability. We live in the age of transparency, and organizations that construct an image that is not truthful will face consequences in today's socially connected and conscious world. …

Aggregation Of Sediment And Bacteria With Mucilage From The Opuntia Ficus-Indica Cactus, Audrey Lynn Buttice

USF Tampa Graduate Theses and Dissertations

Flocculants are commonly used in industrial settings where solid-liquid separations are desired including industrial and municipal wastewater management and potable water production facilities. Conventional flocculants include inorganic metal salts and synthetic organic polymers. The cost, availability, and harmful effects of the non-biodegradable nature of these flocculants have led to the widespread study of natural flocculants. Current natural flocculants being studied include polysaccharides cultivated from microbial extracellular matrix products and plant based materials. In this study, the mucilage of Opuntia ficus-indica cactus was evaluated as a natural flocculant for sediments and bacteria. The O. ficus-indica cactus is also known as the …

USF Tampa Graduate Theses and Dissertations

Sweetwater Organic Community Farm is an organic farm and environmental education center located in Tampa, Florida. The farm employs the community supported agriculture (CSA) model, in which members pay a single fee before the growing season begins and receive a weekly or biweekly share of the ongoing harvest in return. Using multiple ethnographic methods, this research aimed to understand the daily operations at Sweetwater as well as the perceptions of staff and CSA members. Findings indicated that there were myriad perceived advantages of organic agriculture but also imposing challenges that needed to be overcome. Moreover, staff members acknowledged the challenges …

Water's Dependence On Energy: Analysis Of Embodied Energy In Water And Wastewater Systems, Weiwei Mo

USF Tampa Graduate Theses and Dissertations

Water and wastewater treatment is a critical service provided for protecting human health and the environment. Over the past decade, increasing attention has been placed on energy consumption in water and wastewater systems for the following reasons: (1) Water and energy are two interrelated resources. The nexus between water and energy can intensify the crises of fresh water and fossil fuel shortages; (2) The demand of water/wastewater treatment services is expected to continue to increase with increasing population, economic development and land use change in the foreseeable future; and (3) There is a great potential to mitigate energy use in …

Institutions For Managing Ecosystem Services, Jennifer H. Allen, Jenny Duvander, Ida Kubiszewski, Elinor Ostrom

Institute for Sustainable Solutions Publications and Presentations

Two decades of research into the management of what economists call common-pool resources suggests that, under the right conditions, local communities can manage shared resources sustainably and successfully. These revolutionary findings challenge the long-held belief in the "tragedy of the commons." Instead, we have found that tragedy is not inevitable when a shared resource is at stake, provided that people communicate. In many places—from Swiss pastures to Japanese forests—communities have come together for the sake of the environment and their own long-term well-being. Common-pool resources have two features: first, they are shared resources whose use by one person makes them …
