Sustainability Perceptions In The Brewing Industry: Regional/Regional Craft, Microbreweries And Brewpubs, William B. Pierson 2015 Kennesaw State University

Sustainability Perceptions In The Brewing Industry: Regional/Regional Craft, Microbreweries And Brewpubs, William B. Pierson

Symposium of Student Scholars

The purpose of this study is to identify sustainability perceptions within the US brewing industry. In 2014, we disseminated an online survey to all regional/regional craft breweries, microbreweries and brewpubs as identified by the Brewer's Association, 2012 (http://www.brewersassociation.org/). We employed statistical analysis to determine if there was a significant difference among the three categories of breweries found in urban and urban clusters regarding their self-assessment of sustainability. Findings indicate that regional/regional craft breweries and microbreweries tend to score higher in their self-assessment when compared to brewpubs.

The methods consisted of a hybrid model using both quantitative and qualitative modalities, especially focusing on personal interviews, focus group discussions, field observation, and GIS data capturing. GIS based comparisons could not be made because of a lack of available GIS demographic data for the area. The combined modalities approach (especially the in-depth interviews …


Effects Of Physical Characteristics Of Urban Storm Sewersheds On Water Quality In Bloomington, Il, Alicia Terese O'Hare 2015 Illinois State University

Effects Of Physical Characteristics Of Urban Storm Sewersheds On Water Quality In Bloomington, Il, Alicia Terese O'Hare

Theses and Dissertations

Increasing urbanization has consequences for surface water quality. Stormwater is a large component of urban water degradation that is poorly understood. Precipitation is quickly transported via underground pipes, from the land to the stream without following water's natural flow path. Studies have correlated detention ponds with improved water quality and impervious surface cover with degraded water quality. However, other physical characteristics within a storm sewer shed including the presence of sump pumps, area and pipe miles may also affect the stormwater quality. We chose 18 storm sewer systems in Bloomington, IL. We measured pH, temperature, conductivity, dissolved oxygen, chloride, nitrate, …

A Contemporary Decennial Examination Of Changing Agricultural Field Sizes Using Landsat Time Series Data, Emma V. White, David P. Roy

GSCE Faculty Publications

Field size distributions and their changes have not been studied over large areas as field size change datasets are not available. This study quantifies agricultural field size changes in a consistent manner using Landsat satellite data that also provide geographic context for the observed decadal scale changes. Growing season cloud-free Landsat 30 m resolution images acquired from 9 to 25 years apart were used to extract field object classifications at seven sites located by examination of a global agricultural yield map, agricultural production statistics, literature review, and analysis of the imagery in the US Landsat archive. High spatial resolution data …


Geospatial Analysis Of Smart Growth And Transit Oriented Developments, Michelle J. Nichols 2015 University of Denver

Geospatial Analysis Of Smart Growth And Transit Oriented Developments, Michelle J. Nichols

Geography and the Environment: Graduate Student Capstones

Rapid population growth, water and air pollution, overloaded public services, and traffic congestion can stress economies and result in unsustainable communities. Geographic Information Science (GIS) is a valuable technology for reversing negative these types of trends by identifying areas that may presently exhibit Smart Growth characteristics. Rather than expand on the current transportation infrastructure and develop new Smart Growth communities, San Diego Metropolitan’s Transit System (SDMTS) intends to use this study to review the current transit routing infrastructure in an effort to support communities exhibiting Smart Growth potential. Communities along existing transportation infrastructure will analyzed as potential Smart Growth and …


Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton 2015 University of Brest

Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton

Journal of Ocean and Coastal Economics

Peer review is a necessary process with a long history of complaints, including over-solicitation of a small number of reviewers, delays, inadequate numbers of reviewers, and a lack of incentives to provide strong reviews or avoid reviews with little helpful information for the author. In the era of Web-based distribution of research, through working paper or project reports, anonymous peer reviews are much less likely. The Journal of Ocean and Coastal Economics will use signed peer reviews and an open communication process among authors, reviewers, and editors. This approach, to be developed over time, should lead to stronger communication of …


Who Is At The Forest Restoration Table? Final Report On The Blue Mountains Forest Stewardship Network, Phase 1, Rebecca J. McLain, Kirsten Wright, Lee Cerveny 2015 Portland State University

Who Is At The Forest Restoration Table? Final Report On The Blue Mountains Forest Stewardship Network, Phase 1, Rebecca J. Mclain, Kirsten Wright, Lee Cerveny

Institute for Sustainable Solutions Publications and Presentations

Forest collaboratives have emerged throughout the western U.S. as a governance model to address complex ecological challenges that occur at the landscape scale across multiple landownerships and jurisdictional boundaries. Collaborative groups typically involve multiple parties with diverse interests working together to address complex management challenges. Collaboratives often provide input on or make recommendations about public lands actions and decisions. The Blues Stewardship Project was developed to better understand the size, composition, participation, and diversity of forest collaboratives and to identify organizations that may not currently be represented at the collaborative ‘table.’

The study focuses on five collaborative groups in the …

Estimation Of Crop Gross Primary Production (Gpp): Ii. Do Scaled Modis Vegetation Indices Improve Performance?, Qingyuan Zhang, Yen-Ben Cheng, Alexei I. Lyapustin, Yujie Wang, Xiaoyang Zhang, Andrew Suyker, Shashi Verma, Yanmin Shuai, Elizabeth M. Middleton

GSCE Faculty Publications

Satellite remote sensing estimates of gross primary production (GPP) have routinely been made using spectral vegetation indices (VIs) over the past two decades. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), the green band Wide Dynamic Range Vegetation Index (WDRVIgreen), and the green band Chlorophyll Index (CIgreen) have been employed to estimate GPP under the assumption that GPP is proportional to the product of VI and photosynthetically active radiation (PAR) (where VI is one of four VIs: NDVI, EVI, WDRVIgreen, or CIgreen). However, the empirical regressions between VI*PAR and …
