Conflicting Discourses Of Participatory Postdevelopment In Community-Led Total Sanitation, Shaina M. Pomerantz Kasper

Honors Projects

The development community perceives the current “sanitation crisis” to be remedied with water, sanitation and hygiene initiatives. While the participatory process of Community-Led Total Sanitation (CLTS) incorporates community involvement, it still imposes globalized sanitation norms and a dominant external worldview. Using discourse analysis of the CLTS handbook, I argue that CLTS structurally advocates for continuing local hierarchies, promotes external technologies, enforces the power of outside development facilitation, and creates a new sanitation paradigm. Communities continue to resist sanitation development such as CLTS because of its top-down structure. I conclude by offering policy recommendations to improve the CLTS process.

A Need For Green: An Approach For Motivating Environmentally Sustainable Practices At The University Of Rhode Island, Alyssa Mason, Mary Vidal

Senior Honors Projects

“Never underestimate the power of a few committed people to change the world. Indeed, it is the only thing that ever has." -Margaret Meade

Colin Beavan’s No Impact Man details his yearlong experiment to live without creating any environmental impact. As sophomores we were inspired by Beavan’s journey but also skeptical of living a completely no-impact lifestyle as college-students. Although we were motivated to try to live sustainably, our efforts were dormant until our junior year. That year we decided that we would attempt to live up to the standards set forth by Beavan--understanding that some practices would ...

Agricultural Development In The Northern Savannah Of Ghana, Tara N. Wood

Doctoral Documents from Doctor of Plant Health Program

Since declaring independence in 1957, the Republic of Ghana has become a stable constitutional democracy. Ghana’s economy has grown substantially over the past decade, yet remains primarily agrarian, accounting for 50% of the total employment and 25% of the country’s Gross Domestic Product. Smallholder rain-fed farming using rudimentary technologies dominates the agricultural sector accounting for 80% of total agricultural production. Approximately 90% of smallholder farms are less than two hectares in size, and produce a diversity of crops. The major crops cultivated in Ghana include numerous cereal, root and tuber, leguminous, fruit, vegetable and industrial crops. Maize is ...

Gene Expression Response In Early Developmental Stages Of Rainbow Trout Exposed To Ecologically Relevant Concentrations Of Malathion, Susan Miller

Theses and Dissertations

Understanding the early life stage toxic effects of environmental organophosphate exposure on organism health is crucial to identifying biomarkers that can be used for preventative care. Malathion, a potent organophosphate, is one of the most widely used organophosphates in agriculture and pest eradication. Due to its widespread use, pesticide runoff into area bodies of water poses a great threat to aquatic life and human inhabitants. Acute exposure to high concentrations of malathion causes neurological abnormalities and can result in respiratory failure, muscle spasms, and mental confusion in humans.

In the present study, the effects of malathion are observed following acute ...

Effects Of Salinity On The Toxicity Of Ionic Silver And Ag-Pvp Nanoparticles To Tisbe Battagliai And Ceramium Tenuicorne, Ailbhe Macken, Hugh Byrne, Kevin V. Thomas

Articles

The toxic effects of polyvinylpyrrolidone (PVP) coated silver nanoparticles (Ag-NP_PVP) and ionic Ag, to Tisbe battagliai (Tb) and Ceramium tenuicorne (Ct) were investigated and the usefulness of standardised marine guidelines for ENP risk assessment were assessed. The toxicity of Ag-NP_PVP [CtEC₅₀ = 26.6 µg/L, TbEC₅₀ = 7.9 µg/L] and Ag⁺ [CtEC₅₀ = 2312.2µg/L, Tb EC₅₀ = 90.9 µg/L] to both test species differed, with the silver ENPs being more toxic. In contrast to Ag⁺ the toxicity of Ag-NP_PVP increased significantly with increasing salinity, however, after thorough characterisation it was ...

Are We Seeking Pimatisiwin Or Creating Pomewin? Implications For Water Policy, Patti Laboucane-Benson, Ginger Gibson, Allen Benson, Greg Miller

The International Indigenous Policy Journal

The purpose of this discussion is to describe the worldview and sacred relationship of the Cree people in Alberta, as well as how colonial policy has created despair (pomewin) in Aboriginal communities and a state of disconnectedness from the water. It concludes with the presentation of a framework for the development of policies that seek to repair the relationship between Aboriginal people and mainstream society – with the potential to create the good life, broadly defined (pimatisiwin) for all Albertans (Aboriginal and non-Aboriginal). This discussion is based upon the findings of a three-year research project entitled “The Sacred Relationship”. The goals ...

Environews #1, Richard B. Philp

Richard B. Philp

Environews #1 is, hopefuly, the first of a series dealing with current issues of environmental concern. This issue discusses the possible role of climate change in the massive floods that followed hurricane sandy, depletion of the world's fish stocks, the possible role, bothe positive and negative, of aquaculture, and the trend to seek oil in increasingly environmentally dangerous venues.

Cadmium Accumulation And Distribution In Lettuce And Barley, Fardausi Akhter

University of Western Ontario - Electronic Thesis and Dissertation Repository

Cadmium (Cd) is a non-essential trace element and its environmental concentrations are increasing due to human activities. Edible plants can accumulate high concentrations of Cd, which could be toxic to humans. Understanding how and where Cd is stored in plants is important for ensuring lower concentration of Cd in the food. In this thesis, the accumulation and distribution of Cd in three agricultural plants, namely lettuce (Lactuca sativa L.), barley (Hordeum vulgare L.) and radish (Raphanus sativus L.), were investigated with a focus on the potential mechanisms involved in the localization of Cd in the root. The main objectives of ...

Continental-Scale Characterization Of Molecular Variation In Quaking Aspen, Colin M. Callahan

All Graduate Theses and Dissertations

Quaking aspen (Populus tremuloides) has the largest natural distribution of any tree native to North America, ranging from Alaska through the breadth of Canada and south to mid-Mexico. The Laurentide ice sheet occupied most of the current range of P. tremuloides until the late Pleistocene epoch, so this species has undergone a significant, geologically recent range expansion. Surprisingly, range-wide patterns of genetic variation in P. tremuloides have never been described. Using a sample set representing the full longitudinal and latitudinal extent of the species distribution, I have conducted a phylogeographic analysis for P. tremuloides. Preliminary results comparing both nuclear and ...
