The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly
The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly
Humboldt Journal of Social Relations
In the wake of the timber wars, communities across the American West have struggled to redefine their relationships to nearby federal forests. The timber-dependent model of the pre-Timber War era, with clear timber targets and economic outputs, has been replaced by more nuanced and less clearly-defined model: ecosystem management. This case study research uses interviews with participants in the Weaverville Community Forest (WCF) to explore the role of a community in managing its nearby federal lands. Momentum for the WCF flowed from a small group of citizens who were invested in the forest despite their cultural and ideological differences regarding …
Beyond 'Owls Versus Jobs': A Twenty-Year Retrospective Of The Headwaters Forest Controversy, Jennifer Bernstein
Beyond 'Owls Versus Jobs': A Twenty-Year Retrospective Of The Headwaters Forest Controversy, Jennifer Bernstein
Humboldt Journal of Social Relations
In 1999, the Headwaters Forest Reserve was established in Humboldt County after more than 20 years of community activism, negotiations, and litigation. The ‘last stand’ of unprotected, privately-owned old growth redwood had finally been safeguarded, though many on the North Coast felt that the final deal fell far short of what was needed to protect the watershed’s ecological functioning. This article uses academic and journalistic research, supplemented by oral histories, to make three main points about the North Coast ‘post deal.’ One, forest management practices in the region have evolved to be more consistent with the practices of ecological forestry. …
An Opportunity To End The Timber Wars: How Collaboration In Southeast Alaska Has Helped To Dissipate Conflict, Diana K. Portner
An Opportunity To End The Timber Wars: How Collaboration In Southeast Alaska Has Helped To Dissipate Conflict, Diana K. Portner
Humboldt Journal of Social Relations
Forest management in the Tongass National Forest has been a topic of controversy for decades, due to the result of intense timber extraction in the mid-twentieth century. In recent years, collaborative approaches to management, beginning with a federally chartered advisory committee, have offered opportunities to overcome the seemingly intractable conflict. While a new culture of collaboration is emerging in Southeast Alaska, the region still faces challenges associated with the implementation of these approaches. This commentary explores the history of the conflict, factors that contributed to the success of collaborative approaches to land management in the region, and continued challenges that …

Life Cycle Assessment Of Four Different Sweaters, Sarah Nolimal
Life Cycle Assessment Of Four Different Sweaters, Sarah Nolimal
DePaul Discoveries
Life cycle assessment (LCA) is a methodological tool to describe the impacts of a product over its lifetime, from ‘cradle to grave.’ Despite increased employment of LCA, textile LCA studies are often private, outdated, not transparent, or lack accurate data. Further, we know of no LCA study specific to sweaters. This screening LCA combines published literature and data from OpenLCA databases (Ecoinvent 3.3 and GaBi Professional) to conduct a comparative LCA for four sweaters. To determine the composition of these sweaters, we massed and assessed the material composition of 117 sweaters in October 2015. Based on results, our study compares …

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
Celebration of Learning
Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Student Theses 2015-Present
This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Design Guidelines And Strategies For Thermal Solar Management Of Fenestration In The Desert Climate, David Mccredo
UNLV Theses, Dissertations, Professional Papers, and Capstones
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 …

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister
Graduate Student Portfolios, Professional Papers, and Capstone Projects
The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2). …

Immersed In Fire: The Use Of Virtual Reality As An Attitude Assessor And Boundary Object In Wildland Fire Management, Casey Olechnowicz
Electronic Theses and Dissertations
Interest in using prescribed burning as a forest management tool to promote forest health and regeneration is growing in Maine. The goal for this research was to better understand the way that the public perceives prescribed burning practices in wildland-urban interfaces, with an emphasis placed on how immersive imagery, closely related to virtual reality (VR), compares to traditional communication methods. We specifically focus on the social acceptability of prescribed burning and analyze how the level of immersive imagery is related to that acceptability (Ahn, 2015; Bricken, 1990; Fogg, Cuellar, and Danielson, 2009; Smith 2015; Wiederhold, Davis, and Wiederhold, 1998).

Rubenstein School of Environment and Natural Resources Faculty Publications
Rumen microorganisms are the origin of many bioactive fatty acids (FA) found in ruminant-derived food products. Differences in plant leaf anatomy and chemical composition between cool- and warm-season pastures may alter rumen microorganisms, potentially enhancing the quantity/profile of bioactive FA available for incorporation into milk. The objective of this study was to identify rumen bacteria and protozoa and their cellular FA when cows grazed a warm-season annual, pearl millet (PM), in comparison to a diverse cool-season pasture (CSP). Individual rumen digesta samples were obtained from five Holstein cows in a repeated measures design with 28-day periods. The treatment sequence was …

Successfully meeting the mitigation and adaptation targets of the Paris Climate Agreement (PA) will depend on strengthening the ties between forests and agriculture. Climate-smart land use can be achieved by integrating climate-smart agriculture (CSA) and REDD+. The focus on agriculture for food security within a changing climate, and on forests for climate change mitigation and adaptation, can be achieved simultaneously with a transformational change in the land-use sector. Striving for both independently will lead to competition for land, inefficiencies in monitoring and conflicting agendas. Practical solutions exist for specific contexts that can lead to increased agricultural output and forest protection. …

Analysis Of Surface Integrity In Machining Of Aisi 304 Stainless Steel Under Various Cooling And Cutting Conditions, F. Klocke, B. Döbbeler, S. Lung, S. Seelbach, Ibrahim S. Jawahir
Institute for Sustainable Manufacturing Faculty Publications
Recent studies have shown that machining under specific cooling and cutting conditions can be used to induce a nanocrystalline surface layer in the workspiece. This layer has beneficial properties, such as improved fatigue strength, wear resistance and tribological behavior. In machining, a promising approach for achieving grain refinement in the surface layer is the application of cryogenic cooling. The aim is to use the last step of the machining operation to induce the desired surface quality to save time-consuming and expensive post machining surface treatments. The material used in this study was AISI 304 stainless steel. This austenitic steel suffers …
