No matter how you define it, corporate social responsibility (CSR) is a hot topic. From community investing to business ethics to environmental sustainability and beyond, proponents of CSR view the business landscape through a lens that focuses less on profitability and more on the greater good.
“Doing well by doing good” is the business world’s new mantra. Concepts of CSR, green business, social entrepreneurship, and peace through commerce have become a focus of research and are inspiring the next generation of businesspeople. The 2010 BRASS Program gave attendees an expert’s view of certain niches within the broader realm ...

Chemistry Faculty Publications and Presentations
During the 2006 Texas Air Quality Study and Gulf of Mexico Atmospheric Composition and Climate Study (TexAQS-GoMACCS 2006), the optical, chemical and microphysical properties of atmospheric aerosols were measured on multiple mobile platforms and at ground based stations. In situ measurements of the aerosol light extinction coefficient (σep) were performed by two multi-wavelength cavity ring-down (CRD) instruments, one located on board the NOAA R/V Ronald H. Brown (RHB) and the other located at the University of Houston, Moody Tower (UHMT). An AERONET sunphotometer was also located at the UHMT to measure the columnar aerosol optical depth (AOD). The σep ...
A Dynamic Physical Model For Soil Temperature And Water In Taylor Valley, Antarctica, 2010 Colorado State University - Fort Collins
A Dynamic Physical Model For Soil Temperature And Water In Taylor Valley, Antarctica, H. W. Hunt, Andrew G. Fountain, Peter T. Doran, Hassan J. Basagic
Geography Faculty Publications and Presentations
We developed a simulation model for terrestrial sites including sensible heat exchange between the atmosphere and ground surface, inter- and intra-layer heat conduction by rock and soil, and shortwave and longwave radiation. Water fluxes included snowmelt, freezing/thawing of soil water, soil capillary flow, and vapour flows among atmosphere, soil, and snow. The model accounted for 96-99% of variation in soil temperature data. No long-term temporal trends in soil temperature were apparent. Soil water vapour concentration in thawed surface soil in summer often was higher than in frozen deeper soils, leading to downward vapour fluxes. Katabatic winds caused a reversal ...

Numerical Analysis Of Non-Constant Pure Rate Of Time Preference: A Model Of Climate Policy, 2010 Singapore Management University
Numerical Analysis Of Non-Constant Pure Rate Of Time Preference: A Model Of Climate Policy, Tomoki Fujii, Larry Karp
Research Collection School Of Economics
When current decisions affect welfare in the far-distant future, as with climate change, the use of a declining pure rate of time preference (PRTP) provides potentially important modeling flexibility. The difficulty of analyzing models with non-constant PRTP limits their application. We describe and provide software (available online) to implement an algorithm to numerically obtain a Markov perfect equilibrium for an optimal control problem with non-constant PRTP. We apply this software to a simplified version of the numerical climate change model used in the Stern Review. For our calibration, the policy recommendations are less sensitive to the PRTP than widely believed.
Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, 2010 Edith Cowan University
Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, Victoria S. Lazenby
Theses: Doctorates and Masters
Formaldehyde is a common air pollutant that tends to be found in elevated concentrations in indoor air. Exposure to formaldehyde has the potential to impact on respiratory health, particularly amongst sensitive individuals and populations, including children. Children spend most of their time indoors at home, however, there are very little data on the contribution of formaldehyde concentrations in homes to personal exposure in children. The principal aim of this cross sectional study was to investigate whether the domestic environment is the most significant source of personal exposure of formaldehyde in children. Forty-one primary school children (aged between 8 and 12 ...
Sorption Of Bovine Serum Albumin On Nano And Bulk Oxide Particles, 2010 University of Massachusetts Amherst
Sorption Of Bovine Serum Albumin On Nano And Bulk Oxide Particles, Lei Song
Masters Theses 1911 - February 2014
Manufactured oxide nanoparticles (NPs) have large production and widespread applications, which will inevitably enter the environment. NPs can interact with proteins in living beings due to the fact that NPs can transport into blood or across cell membranes into cells. Conformational change of protein molecules after sorption on oxide NPs has been reported. Therefore, it is important to understand the adsorption mechanism of protein onto oxide NPs surfaces. Although few works have reported protein adsorption behaviors, a general systematic comparison of the effects of particle size and surface groups on protein adsorption by widely studied NPs still needs to be ...
Spatial Ecology Of Eastern Coyotes (Canis Latrans) In The Anthropogenic Landscape Of Cape Cod, Massachusetts, 2010 University of Massachusetts Amherst
Spatial Ecology Of Eastern Coyotes (Canis Latrans) In The Anthropogenic Landscape Of Cape Cod, Massachusetts, Maili Page
Masters Theses 1911 - February 2014
Historically, coyotes were associated with the western United States. During their expansion eastward, coyotes have become more tolerant of humans and have been able to live in varying degrees of urbanization. One main question ecologists around the country are asking is how coyotes are surviving in anthropogenic environments. To aid in answering this question, I have compared coyote land use preference generally and specifically during coyote breeding season, winter and summer, human tourist seasons, and day and night. I also compared coyote land cover preference for deciduous and evergreen cover types during natural seasons. I found that, in general, there ...

Pollinator Populations In Massachusetts Cranberry, 1990 To 2009: Changes In Diversity And Abundance, Effects Of Agricultural Intensification, And A Contribution To The North American Pollinator Survey., Molly M. Notestine
Masters Theses 1911 - February 2014
It is now widely accepted that over one-third of the global food supply depends upon pollinators. Risking severe ecological and economic implications, the status of the 4000 species of bees native to North America has been poorly understood due to a lack of long-term survey data. In this study, I conducted bee surveys on Massachusetts cranberry (Vaccinium macrocarpon Ait.) bogs from 2007-2009 and compared diversity and abundance data to those from historical surveys performed in 1990-1992 on the same bogs. I found that overall bee diversity declined severely in the 19-year survey period, while total bee abundance remained consistent. My ...
Bolivia's Coca Headache: The Agroyungas Program, Inflation, Campesinos, Coca And Capitalism In Bolivia, 2010 University of Massachusetts Amherst
Bolivia's Coca Headache: The Agroyungas Program, Inflation, Campesinos, Coca And Capitalism In Bolivia, John D. Roberts
Masters Theses 1911 - February 2014
Bolivia in the 1980s was wracked by monetary inflation approaching levels of the German Weimar Republic. Immediately following this time of great financial crisis in Bolivia, the U.N. founded a project through the U.N.D.P. to encourage peasant farmers in Bolivia to switch from growing coca (the plant used manufacture cocaine) to growing other cash crops for market. This crop substitution and development program, called the Agroyungas Project, lasted from 1985 to 1991 and is the focus of this study. While many U.N. pundits and journalists considered the program’s initial small successes promising, it has ...
Nitrogen Dioxide In The Urban Forest: Exposure And Uptake, 2010 University of Massachusetts Amherst
Nitrogen Dioxide In The Urban Forest: Exposure And Uptake, Tanner B. Harris
Masters Theses 1911 - February 2014
Nitrogen dioxide (NO2) levels were measured inside and adjacent to canopies of urban trees in Springfield, MA, over two growing seasons. Nitrogen dioxide levels were consistently and significantly higher inside tree canopies compared to levels outside. During the second growing season, ozone (O3), temperature, and relative humidity (RH) were also measured using samplers co-located with the NO2 samplers. Ozone levels were significantly lower inside the canopy whereas temperatures were higher inside the canopy, and RH was not different between inner and outer canopy locations. The results corroborate theoretical models predicting elevated NO2 and depressed O3 levels inside tree canopies based ...
An Evaluation Of Duck And Ring-Necked Pheasant Nest Survival And Nest Density In Relation To Patch Size And Landscape Variables In Eastern South Dakota, Keith J. Fisk
Electronic Theses and Dissertations
Grassland ecosystems in South Dakota have experienced significant transformations over the last 100 years. Landscapes are currently dominated by large agricultural fields interspersed with small, isolated grassland patches. These isolated grassland patches are hypothesized to experience decreased nest survival rates for ring-necked pheasants (Phasianus colchicus) and dabbling duck species due to small size and high degrees of fragmentation. Several natural resource agencies currently conserve grasslands throughout eastern South Dakota, but wildlife managers seek more information on how the size and spatial arrangement of grasslands affect targeted conservation strategies. Therefore, the objectives of this study were to: (1) evaluate the relationship ...
Analysis Of Eurycea Hybrid Zone In Eastern Missouri, 2010 Missouri University of Science and Technology
Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley
"Evolutionary mechanisms are often difficult to observe in action because evolution generally works slowly over time. Hybrid zones provide a unique opportunity to observe many evolutionary processes, such as reinforcement, because of the rapid changes that tend to occur in these zones. Salamanders provide an ideal model for examining the rapid changes in populations that result from hybridization because many closely-related species lack reproductive barriers. In Missouri, a well-documented hybridization zone exists among the two subspecies Eurycea longicauda longicauda (long-tailed salamander) and E. L. melanopleura (dark-sided salamander). These salamanders inhabit caves, limestone creek beds, and abandoned mine shafts. A closely ...
Laryngeal Apparatus And Call Structure In North American Hylids, 2010 Missouri University of Science and Technology
Laryngeal Apparatus And Call Structure In North American Hylids, Barbara Ann Catherine Fears
"Although the ecological implications and structure of frog calls have been the subject of much study, little is known about the association between the laryngeal apparatus morphology and call structure in North American hylids. In this study linear measurements of the laryngeal apparatus were captured and compared to the call structures of thirteen species of North American hylids. Species examined included: Pseudacris crucifer, P. triseriata, P. ocularis, Acris crepitans blanchardi, Hyla avivoca, H. cinerea, H. gratiosa, H. chrysoscelis, H. versicolor, H. squirella, H. femoralis, H. arenicolor, and H. eximia. Six homologous landmark points were identified, and the lengths between them ...
The Role Of Skeletal Development In Body Size Evolution Of Two North American Frogs, 2010 Missouri University of Science and Technology
The Role Of Skeletal Development In Body Size Evolution Of Two North American Frogs, Sarah Beth Havens
"In order to better understand the evolution of miniaturization in Acris blanchardi, a North American Hylid with a unique life history and of ecological interest in the United States. The development and ossification sequences of 48 larvae, 5 juveniles and 5 adult A. blanchardi were examined. The adult was described by Maglia et al. (2007) to be a miniature and to display morphological novelties. In addition, 44 larvae, 2 juvenile and 5 adults of Pseudacris crucifer a closely related frog that has been suggested to be a miniature, were examined. The cranial and postcranial adult elements of this species, as ...
Zinc Oxide Nanoparticle Disruption Of Store-Operated Calcium Entry In A Muscarinic Receptor Signaling Pathway, 2010 Missouri University of Science and Technology
Zinc Oxide Nanoparticle Disruption Of Store-Operated Calcium Entry In A Muscarinic Receptor Signaling Pathway, Hsiu-Jen Wang
"The influences of ZnO nanoparticles on cellular responses to activation of muscarinic receptors were studied in Chinese hamster ovary cells expressing the human M3 muscarinic acetylcholine receptor. ZnO particles (20 nm) induced cytotoxicity in a time and concentration-dependent manner: following a 24 h exposure, toxicity was minimal at concentrations below 20 µg/ml but virtually complete at concentrations above 28 µg/ml. ZnO particles did not affect antagonist binding to M3 receptors or allosteric ligand effects, but increased agonist binding affinity while eliminating guanine nucleotide sensitivity. At a noncytotoxic concentration (10 µg/ml), ZnO increased resting [Ca²⁺]i from 40 ...
Modeling Decision Making Related To Incident Delays During Hurricane Evacuations, 2010 Old Dominion University
Modeling Decision Making Related To Incident Delays During Hurricane Evacuations, Robert Michael Robinson
Computational Modeling and Simulation Engineering Theses & Dissertations
Successful evacuations from metropolitan areas require optimizing the transportation network, monitoring conditions, and adapting to changes. Evacuation plans seek to maximize the city's ability to evacuate traffic to flee the endangered region, but once an evacuation begins, real time events degrade even the best plans.
To better understand behavioral responses made during a hurricane evacuation, a survey of potential evacuees obtained data on demographics, driving characteristics, and the traffic information considered prior to and during an evacuation. Analysis showed significant levels of correlation between demographic factors (e.g., gender, age, social class, etc.) and self-assessed driver characteristics, but limited ...
Impacts Of The Spotted Spiny Lobster (Panulirus Guttatus) On The Long-Spined Sea Urchin (Diadema Antillarum) And Patch Reef Communities In The Florida Keys, Meredith D. Kintzing
Biological Sciences Theses & Dissertations
Caribbean coral reefs have undergone a phase shift from a system dominated by corals to one where algae are pervasive. This shift was precipitated by the loss of herbivores, including the mass mortality of the long spined sea urchin (Diadema antillarum), coupled with disease and the recruitment failure of hermatypic corals. Diadema populations have recovered in some areas of the Caribbean, but are still below historical levels in the Florida Keys, likely due to low larval supply coupled with predation on juveniles. Lobsters are sea urchin predators in other systems and the spotted spiny lobster (Panulirus guttatus ) is abundant on ...
Status Of Wintering Grassland Birds In A Post-Hurricane, Salvage-Logged Forest, 2010 Louisiana State University and Agricultural and Mechanical College
Status Of Wintering Grassland Birds In A Post-Hurricane, Salvage-Logged Forest, Matthew Edward Brooks
LSU Master's Theses
North American grassland birds have been declining at an alarming rate. Winter habitat for grassland species in the southeastern U.S. generally occurs within forests subject to management. I studied wintering grassland bird communities in De Soto National Forest in southern Mississippi. My objectives were to: 1) Assess bird communities and vegetation structure in upland forest stands that were salvage-logged following Hurricane Katrina, in stands managed for Red-cockaded Woodpeckers (Picoides borealis, RCW), and in stands containing bogs; and 2) Determine the extent of the association between vegetation and occurrence of the common wintering grassland birds. I conducted bird and vegetation ...
Developing Tools To Identify Factors That Limit Production In Coastal Marshes, 2010 Louisiana State University and Agricultural and Mechanical College
Developing Tools To Identify Factors That Limit Production In Coastal Marshes, Vanessa Danielle Tobias
LSU Doctoral Dissertations
Marsh loss is a problem in many areas around the world. In Louisiana’s coastal marshes, where Spartina patens is the most common plant, restoration and management seek to slow wetland loss rates that average approximately 77.4 km2/year. To combat the problem, scientists and managers require tools to determine local causes and evaluate the effectiveness of management techniques. Current methods for identifying factors that limit productivity in marshes are too time-consuming or expensive for wide-spread, regular use. Critical values of elemental concentrations in plant tissue are widely used to diagnose mineral deficiencies and toxicities in agricultural crops, however ...
