The Triple Bottom Line And Social Responsibility Framework In Public Sector Management, Matthew Ajiake

Walden Dissertations and Doctoral Studies

Leaders of public sector agencies must incorporate the voices of diversified stakeholders into planning and decision-making processes. With aging infrastructures around the world, public agencies are challenged to move public benefit projects forward when citizens are not engaged or empowered to participate in the process. The purpose of this triple bottom line (social, ecological, and financial) and social responsibility study was to explore whether public sector organizations are socially responsible by law. A case study was developed using data from publicly available documents and interviews that explored how the San Francisco Public Utilities Commission (SFPUC) implemented a social responsibility framework …

A Sustainable Design Method Acting As An Innovation Tool, Jeremy Faludi

Dartmouth Scholarship

Product companies generally see sustainability as a burden limiting their design process, similar to cost or safety limits. A method for sustainable design was created, attempting to turn sustainability from a burden into an innovation tool with inherent business value. The method combines creative whole-systems thinking with quantitative sustainability metrics. It facilitates innovation by the creation of visual whole-system maps that encourage more thorough and more radical brainstorming. It facilitates sustainability by using quantitative measurements, such as lifecycle assessment or point-based certification systems, to set priorities and choose final designs. The method has been anecdotally tested in classes at four …

A Central Support System Can Facilitate Implementation And Sustainability Of A Classroom-Based Undergraduate Research Experience (Cure) In Genomics, David Lopatto, Charles Hauser, Christopher J. Jones, Don Paetkau, Randall J. Dejong

University Faculty Publications and Creative Works

In their 2012 report, the President’s Council of Advisors on Science and Technology advocated “replacing standard science laboratory courses with discovery-based research courses”—a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences working with the Genomics Education Partnership, a nationwide faculty consortium that aims to provide undergraduates with a research experience in genomics through a scheduled course (a classroom-based undergraduate research experience, or CURE). We examine the common barriers encountered in implementing a CURE, program elements of most value to faculty, ways in which a shared core support system can help, and the …

The net-zero homes project that this class worked on throughout the semester was designed to determine what it would take to bring a home in Grand Rapids, Michigan to the status of net-zero and whether or not it is feasible to do so. The idea behind a net-zero home is to reduce the energy usage in the home, whether it is by lifestyle changes, insulation additions, or by appliance upgrades, and then produce the remaining energy deficit from renewable sources, so that the homeowner has a net usage of zero at the end of the year. This report details the …

Examining The Effectiveness Of Ecotourism As A Funding Source For Protected Area Management In Guyana, Jordan S. Flagel

Masters Theses, 2010-2019

Protected areas in tropical rainforests serve many important ecosystem services, including carbon sequestration. These areas are often in need of donor or grant funding to operate as governments in tropical forested countries are not always able to provide adequate funds for protection. This paper focuses on the Iwokrama International Center for Rainforest Conservation and Development in the South American country of Guyana, which has had funding issues since the global economic crisis of 2008 and an accompanying shift in donor country financial priorities. Increasing the amount of sustainable ecotourism in the Iwokrama reserve was identified as a potential source for …

Performance Quantification Of Extensive Green Roof Substrate Blend: Expanded Shale And Biochar, James Sheats

Masters Theses, 2010-2019

Urban stormwater management practices often involve the redirection of runoff to local waterbodies. As such, the quality of runoff directly affects the condition of these receiving waters. Green roofs offer many benefits to the urban environment including attractive aesthetics, thermal insulation for buildings and stormwater runoff reduction. Unfortunately, in order to promote the spread of vegetation, fertilization is often practiced that can lead to elevated nutrient concentrations in runoff and, ultimately, nearby streams, rivers and bays. Different amounts of biochar, pyrolyzed biomass, were added to model green roof trays to test for the ability of this charcoal-like substance to prevent …

Switchgrass Cultivar, Harvest Frequency, Fertilizer Source, And Irrigation Effects On Near-Surface Soil Properties In West-Central Arkansas, Alayna A. Jacobs

Graduate Theses and Dissertations

Switchgrass (Panicum virgatum L.) has been identified as a model bioenergy feedstock crop and is expected to become an important feedstock for future renewable fuel generation. Agronomic management combinations that maximize monoculture switchgrass yield are generally well understood; however, little is known about corresponding effects of differing switchgrass management combinations on near-surface soil properties. The objective of this research was to determine the residual near-surface soil property effects of three years (2008 to 2011) of consistent management combinations to maximize switchgrass biomass production, including cultivar (‘Alamo’ and ‘Cave-in-Rock’), harvest frequency (1-cut and 2-cut systems per year), fertilizer source (poultry …

Carbon Dioxide Emissions From Switchgrass And Cottonwood Grown As Bioenergy Crops In The Lower Mississippi Alluvial Valley, Michele Lea Helton

Graduate Theses and Dissertations

Marginal land of the Lower Mississippi Alluvial Valley (LMAV) has the potential to be utilized for the production of bioenergy feedstocks. Soil respiration is the gaseous emission of carbon dioxide (CO₂) from microbes and plant roots in the soil, and these emissions play an important role in the global cycling of carbon. Soil respiration can act as a positive feedback affecting climate change, and has been shown to vary depending on soil moisture, temperature, and vegetation. The objectives of this study where to evaluate the effects of land use [switchgrass (Panicum virgatum), cottonwood (Populus deltoides …

The Effects Of Silicon Applications On Wear And Drought Stress Of Cool Season Turfgrass, Mike J. Badzmierowski, W. Michael Sullivan

Senior Honors Projects

The ability of turfgrass to maintain quality and functionality during use and drought stress are fundamental to almost all turfgrass environments. A possible mechanism to increase wear and drought tolerance is through the use of supplemental silicon (Si) application. Until recently, Si has received little attention for its role in crop physiology or performance.

While it is recoverable within the plant it is not recognized as an “essential” plant growth component. Si is the second most abundant element in the Earth’s crust; however the majority of soil-Si is bio-geochemically inert. Plants absorb Si exclusively as monosillicic acid, H₂SiO …

Ecosystem Services In The Wet Tropics: A Literature Review And Economic Valuation, Alyson Cheney

Independent Study Project (ISP) Collection

The present study can be broken down into two sections. First, it created a literature review on the current body of knowledge regarding ecosystem services in the Australian Wet Tropics World Heritage Area. The second portion of the study was an economic valuation determining how much residents that live in the Wet Tropics value the benefits provided to them through ecosystem services. The literature review found that there were large gaps in the present body of knowledge. Biophysical studies made up the vast majority of the literature and very few ecosystem service economic valuations have been carried out for the …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Empowering Citizens In A Global Era: A Grounded Theory Study Of Community Gardens, Anita Tam

All Dissertations

In our global era, the modern food system can be viewed as consisting of a dominant macro-level corporate food industry, challenged by broad-based meso-level food justice and democracy movements, which are in turn fueled by micro-level community food initiatives. Research has yet to examine the role of community gardens in the context of this complex, multi-level food system. Grounded theory methodology was thus used to explore the deeper meaning of the community gardening experience to participants, in order to better understand the ways in which community gardens may scale up and contribute to democratizing the food system. Analysis of the …

Life Cycle Assessment Projection Of Photovoltaic Cells: A Case Study On Energy Demand Of Quantum Wire Based Photovoltaic Technology Research, Shilpi Mukherjee

Graduate Theses and Dissertations

With increasing clean-energy demand, photovoltaic (PV) technologies have gained attention as potential long-term alternative to fossil fuel energy. However, PV research and manufacture still utilize fossil fuel-powered grid electricity. With continuous enhancement of solar conversion efficiency, it is imperative to assess whether overall life cycle efficiency is also being enhanced. Many new-material PV technologies are still in their research phase, and life cycle analyses of these technologies have not yet been performed. For best results, grid dependency must be minimized for PV research, and this can be accomplished by an analytical instrument called Life Cycle Assessment (LCA).

LCA is the …

Fisheries Management Paper No.266 - Exmouth Gulf Prawn Managed Fishery Bycatch Action Plan 2014-2019. Version 1.0, Department Of Fisheries, Western Australia

Fisheries Management Papers

Bycatch is described as the part of the catch which is returned to the sea (usually referred to as non-retained or discarded) either because it has no commercial value or because legislative requirements preclude it being retained. Thus, this Bycatch Action Plan (BAP) includes unmarketable finfish and invertebrate species, along with endangered, threatened and protected (ETP) species, such as marine mammals, reptiles and some elasmobranchs.

It is Government policy to minimise bycatch in all commercial fisheries. This BAP details a program of actions to address bycatch issues in the Exmouth Gulf Prawn Managed Fishery (EGPMF), in accordance with the EGPMF …
