Journal of Human Performance in Extreme Environments

Background: Prevention of heat illness is of considerable medical interest within the field of occupational work. There are many established methods of perceptual health assessment; however, many are rather unpractical and timely. The objective was to improve the practicality and timeliness of perceptual physiological monitoring; a Heat Thermal Sensation scale has been developed. The usefulness of the scale was assessed on its ability to monitor physiological variable. Materials and Methods: Ten apparently healthy individuals performed physically exerting activity while exposed to 37 °C. Sensation and physiology were measured throughout. Results: The perceptual monitoring scale demonstrated weak positive correlations with human …


Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill Oct 2015

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …


Artificial Reef Attributes And The Relationship With Natural Reefs: Evidence From The Florida Keys, William L. Huth, O. Ashton Morgan, Paul Hindsley Oct 2015

Artificial Reef Attributes And The Relationship With Natural Reefs: Evidence From The Florida Keys, William L. Huth, O. Ashton Morgan, Paul Hindsley

Journal of Ocean and Coastal Economics

Natural or coral reefs represent extremely valuable ecosystems supporting an estimated 25 percent of all marine life, yet recent reports suggest that 75 percent of the world’s natural reefs are under threat from both natural and human stressors. In areas such as the Florida Keys that boasts an expansive mix of natural and artificial reefs, recreational diving on the system provides an important economic contribution to the local community but also potentially contributes to the stress of the existing natural reef system. We develop a revealed and stated preference modeling framework of diver behavior and find that deployment of an …


Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt Oct 2015

Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt

Journal of Ocean and Coastal Economics

In this paper, we consider whether the current “state of the art” of environmental valuation is suitable for producing policy-relevant estimates of the benefits or costs of changes in marine and coastal ecosystems. We review recent changes in European legislation which has meant an increasing demand for economic valuation from the policy and regulatory community. The next section considers, at a more conceptual level, whether the economic “toolbox” and scientific evidence is up to the task of meeting the demand for more evidence-based policy. Finally, three case studies are used to explore the nature of the valuation task and review …


Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain Oct 2015

Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain

Virginia Journal of Science

The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have been profoundly shaped by disturbance. Chestnut blight, hemlock woolly adelgid, emerald ash borer, and other pests have caused declines or functional extirpation of foundation species. Invasive plants like multiflora rose, Oriental bittersweet, and Japanese stiltgrass threaten both disturbed and intact forests. Oaks and other fire-dependent …

Influence Of Ph And Bulk Density On Carbon Dioxide Efflux In Three Urban Wetland Types, Christopher Chappell, Andra Johnson Sep 2015

Influence Of Ph And Bulk Density On Carbon Dioxide Efflux In Three Urban Wetland Types, Christopher Chappell, Andra Johnson

Professional Agricultural Workers Journal

Abstract

The aim of this study was to understand soil carbon dioxide (CO2) efflux of three different urban wetlands and how pH and bulk density relate to soil CO2 efflux of each wetland. The three wetlands were bottomland, upland, and shrub/scrub. The study was conducted over a twenty week period using the Li-Cor 8100 “closed chamber” method to measure soil CO2 efflux. The findings show that the bottomland wetland efflux was significantly higher than the shrub/scrub and upland wetland. The pH of shrub/scrub was significantly higher than the upland. The bulk density of the bottomland was …

Assessing Small And Medium-Sized Farmers' Willingness To Produce Alternative Biofuel Feedstocks, Andra Johnson, Charles Butler

Professional Agricultural Workers Journal

Abstract

The study assessed the willingness of small and medium-sized farmers to produce alternative biofuel crops in Louisiana and Mississippi. Data were collected from a random sample of 304 participants. The results revealed that the majority of the respondents were males, African Americans, over 50 years, part-time farmers, and a third earned less than $1,000 per year from farming. Most of the respondents (75%) indicated an interest in alternative fuel development, and 72% do not use alternative fuels in their operations. Also, a majority of respondents (83%) indicated that they would like to learn more about opportunities for alternative fuel …


Screening Of Olive Cultivars For Tolerance To Fusicladium Oleagineum In South Africa, Zakhele Cyril Msimango Sep 2015

Screening Of Olive Cultivars For Tolerance To Fusicladium Oleagineum In South Africa, Zakhele Cyril Msimango

Professional Agricultural Workers Journal

Abstract

This study evaluated commercial olive cultivars for resistance to olive leaf spot (OLS). A growth chamber trial was undertaken with one temperature treatment (16°C) applied during inoculation while a relative humidity (RH) of above 80% was maintained. Plants were kept for 48 hours at 99% RH after inoculation and then moved to shade netted area for disease development at a temperature of 25±5°C. The results were used for categorizing the eight olive cultivars evaluated in this study according to their OLS susceptibility. ‘Frantoio’ was categorized as most tolerant; ‘Nandi’ and ‘Leccino’ were found to be moderately tolerant, and ‘Nocellara …

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley Sep 2015

On The Brink: The Melting Of Earth’S Polar Ice Caps, Stephanie Kelley

Kaleidoscope

Research indicates that earth’s polar ice caps are melting at a faster rate than ever before, a product of continued global warming. Unfortunately, side effects of this melting may negatively impact the lives of humans who dwell on this planet. Consequences may include: a significant loss of albedo, a considerable rise in sea levels, damage to aquatic ecosystems, and/or an ice age resulting from the shutdown of major oceanic currents. Although the situation is not yet imminent and the causes not yet pinpointed, the present outlook is too grim to ignore.

The Agricultural Footprints On The Environment, Philip Houtz Aug 2015

The Agricultural Footprints On The Environment, Philip Houtz

Kaleidoscope

Industrialized agricultural systems have given America a convenient and affordable means to supply a surplus of food products to its citizens. Transgenic technology, synthesized fertilizers, advanced pesticides, concentrated animal feeding operations (CAFOs), and the use of farm machinery have all contributed to humanity’s ability to feed the world’s rapidly growing population. However, the energy-intensive food operation of today may not be as ideal as we assume. Fossil fuels are burned to meet the energy requirements for the continual production of large quantities of fertilizer and to keep farm machines operational. Fertilizer and pesticide runoff from farmland ultimately drains into rivers …


Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman Aug 2015

Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman

Journal of Environmental and Resource Economics at Colby

With global population increasing faster than ever, the need to protect land from development is at an all-time high. This paper seeks the measure the public preference for a new national park located in northern Maine. A national park will both protect the land and inject a much-needed economic stimulus to the surrounding communities. The study uses the choice experiment valuation method to quantify its results. Through this revealed preference we can quantify which characteristics are most important to the public so that these characteristics may be considered if the project is ever approved.


Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco Aug 2015

Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco

Journal of Environmental and Resource Economics at Colby

Many studies have been conducted analyzing the economic impact of golf courses on the local communities. These studies examine economic impacts of tournaments, endorsements, and vacation expenses of the major golf courses in the United States. However, there is little research conducted on the environmental impact of Golf courses, specifically in Maine. This paper performs a hedonic pricing analysis using housing prices in proximity to golf courses and compares it to the valuation of various land types in Maine. Housing prices were collected in the towns of Auburn, and North Yarmouth both near and distant from the local golf course. …


Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis Aug 2015

Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis

Journal of Environmental and Resource Economics at Colby

The global agriculture sector is responsible for close 20% of the aggregate anthropogenic greenhouse gas (GHG) emissions emitted since the start of the industrial age. Much of these emissions are attributed to the degradation of soils due to land use change when native ecosystems were converted to agricultural fields. Soil organic carbon (SOC) has been found to decrease in temperate soils when the native (such as a forest or grassland) ecosystem is replace by croplands. The aggregate amount of organic carbon stored in soils globally is estimated be 3.3x the size of the atmospheric carbon pool. Further soil degradation and …


Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson Aug 2015

Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson

Journal of Environmental and Resource Economics at Colby

The Cafe Standards were introduced in 1975 following the Oil Embargo. The goals of this program were simple. To reduce co2 emissions in vehicles by increasing a mandatory average mpg level for car manufacturers in the United States. Recently, in 2012, the Obama Administration set new Cafe Standard requirements for car manufacturers. By 2025, all new cars on the road in the United States must average 54.5 miles per gallon, which would double the current 27 mpg average in place right now. While the intentions of this policy are to reduce co2 emissions while at the same time increasing savings …
