Greenhouse Gas Emission Inefficiency Spillover Effects In European Countries, Levent Kutlu, Ran Wang

Economics and Finance Faculty Publications and Presentations

In our study, we examine whether spatial spillover effects exist for greenhouse gas emission efficiency for 38 European countries between 2005 and 2014. We find that inefficiencies of other countries would lead to lower efficiency levels for a country. This negative inefficiency spillover effect goes down till 2008 then goes up till 2011, then stays relatively stable after 2011. Any strategy to reduce inefficiencies of other countries could potentially improve the efficiency levels. We find that human development index shows significant positive impact on greenhouse gas emission efficiency levels. In particular, one standard deviation increase in human development index would …

Greenhouse Gas Emission Efficiencies Of World Countries, Levent Kutlu

Economics and Finance Faculty Publications and Presentations

Greenhouse gas emissions have increased rapidly since the industrial revolution. This has led to an unnatural increase in the global surface temperature, and to other changes in our environment. Acknowledging this observation, the United Nations Framework Convention on Climate Change started an international environmental treaty. This treaty was extended by Kyoto protocol, which was adopted on 11 December 1997. Using the stochastic frontier analysis, we analyze the efficiencies of countries in terms of achieving the lowest greenhouse gas emission levels per GDP output in the years between 1990–2015. We find that the average greenhouse gas emission efficiencies of world countries …

Using Age To Assess Retention Time Of Ingested Plastic In Seabirds, Tessa G. Nania, Gary Shugart, Peter Hodum

Summer Research

For the past 30 years, plastic pollution research has used plastic ingested and retain in seabirds’ gastrointestinal (GIT) tract as indicators of pollution on different spatial and temporal scales. Types and size of plastic found in birds’ stomachs were used to determine pollution types and severity at different times and places. However, the length of time that birds can retain plastic in their GIT is unknown, making ingested plastic’s use as a bioindicator questionable. We assessed retention times in two seabird species, the Northern Fulmar (Fulmarus glacialis) and the Cassin’s Auklet (Ptychoramphus aleuticus), and compared the …

Light Pollution Research Through Citizen Science, John Kanemoto

STAR Program Research Presentations

Light pollution (LP) can disrupt and/or degrade the health of all living things, as well as, their environments. The goal of my research at the NOAO was to check the accuracy of the citizen science LP reporting systems entitled: Globe at Night (GaN), Dark Sky Meter (DSM), and Loss of the Night (LoN). On the GaN webpage, the darkness of the night sky (DotNS) is reported by selecting a magnitude chart. Each magnitude chart has a different density/number of stars around a specific constellation. The greater number of stars implies a darker night sky. Within the DSM iPhone application, a …

Juxtaposing Nasa’S Aeronet Aod With Carb Pm Data Over The San Joaquin Valley To Facilitate Multi-Angle Imaging Spectroradiometer (Misr) Pm Pollution Research, John Kanemoto

STAR Program Research Presentations

Airborne particulate matter (PM) has been shown to increase the risk for asthma, chronic bronchitis, cardiopulmonary complications, and respiratory cell membrane damage/infection/leakage. PM levels are currently analyzed from two perspectives: stationary land-based monitoring (LBM) sites and total Aerosol Optical Depth (AOD) atmospheric column measurements. Both perspectives often leave miles of space between measuring locations and will have a continually increasing cost from introducing/maintaining sites. The Multi-angle Imaging SpectroRadiometer (MISR) satellite team hopes to begin investigating/archiving PM levels comprehensively via inputting MISR AOD measurements into a function/model which predicts the amount of ground level PM.

In the future, multivariable spatial correlations …

Estimating The Effects Of Urbanization On Carbon Emissions: Evidence In The Philippines, Jerome Abesamis, Jumel Carlo Campos, Cecille Castelle

Angelo King Institute for Economic and Business Studies (AKI)

Urbanization, or the social and economic modernization of metropolitan cities (Poumanyvong & Kaveko, 2010), has obtained unprecedented growth. As an inevitable phase of globalization, it has fuelled society’s consumption patterns, alongside incessant technological development. Mass production and industrialization, the primary thrusts of the global market, require consumption of non-renewable resources arising from the increase in energy usage. These centers of production are concentrated in urban, highly populated areas. This phase of progress, however, comes at the expense of environmental quality. Levels of carbon emissions are concentrated in areas with high population density. This hampers the natural flow of the ecosystem …

Evaluating The Effectiveness Of A Commercial Portable Air Purifier In Homes With Wood Burning Stoves: A Preliminary Study, Julie Hart, Tony Ward, Terry Spear, Richard Rossi, Ph.D., Nicolas Holland M, Brodie Loushin

Safety Health & Industrial Hygiene

Wood burning for residential heating is prevalent in the Rocky Mountain regions of the United States. Studies have shown that wood stoves can be a significant source of PM2.5 within homes. In this study, the effectiveness of an electrostatic filter portable air purifier was evaluated (1) in a home where a wood stove was the sole heat source and (2) in a home where a wood stove was used as a supplemental heat source. Particle count concentrations in six particle sizes and particle mass concentrations in two particle sizes were measured for ten 12-hour purifier on and ten purifier off …

Effects Of 4-N-Nonylphenol On Life-History Traits And Population Dynamics Of A Polychaete, Flemming T. Hansen, Valery E. Forbes, Thomas L. Forbes

Valery Forbes Publications

A Life-Table-Response Experiment lasting 78 d was performed to investigate the toxic effects of sediment-associated 4-n-nonylphenol (NP) on growth, reproduction, and survivorship of isolated hermaphrodites of the infaunal polychaete Capitella sp. I. Demographic effects were evaluated using both a fully age-classified and a simple twostage model to estimate population growth rates (λ). Decomposition analysis was performed to explore the contributions of each of the affected life-history traits to the effects observed on l. Elasticity analysis was applied to examine the relative sensitivity of λ to changes in each of the different life-history traits under different exposure levels.

In the lowest …

Exocrine Pancreatic Neoplasms In The Mummichog (Fundulus Heteroclitus) From A Creosote-Contaminated Site, John W. Fournie, Wolfgang K. Vogelbein

VIMS Articles

A high prevalence of exocrine pancreatic neoplasms occurred in mummichog, Fundulus heteroclitus, from a creosote-contaminated site in the Elizabeth River, Virginia. A total of 20 neoplasms were found in a group of about 1,300 fish obtained at this site over a 2-yr period. Of 240 fish collected during October 1991, 3.3% had pancreatic neoplasms. Adjusted total lesion prevalence for large adult fish (Size Class III: total length = 75–85 mm; Size Class IV: total length > 85 mm) was 6.7%. Pancreatic neoplasms were not observed in 234 fish collected at this site during May 1991, nor were they found in …
