Silicate As The Probable Causative Agent For The Periodic Blooms In The Coastal Waters Of South Andaman Sea, Karthik Raji, Arun Kumar Muthuraj, Gadi Padmavati

Applied Environmental Research

Periodic algal blooms of three diatom species such as Coscinodiscus centralis, Rhizosolenia alata andRhizosolenia imbricata were observedduringSeptember 2011, December 2011 and March 2012 in the coastal waters of South Andaman Sea at Junglighat bay area (11° 39 N and 92° 43 E). The blooms were intense, with Coscinodiscus at aconcentration of 89,000 cells mL-1(contributing 85 to 98% to the total phytoplanktonpopulation), Rhizosolenia alataat a concentration of 13,000 cellsmL-1(86-93%) and Rhizosolenia imbricata at aconcentration of 19,000 cells. mL-1(91-99%). Nutrients, most importantly nitrate and silicate have emerged as the key factors controlling phytoplankton growth in this area

Incremental Concentration Of Black Carbon Aerosol From Road Traffic In Inner Bangkok, Panwadee Suwattiga

Applied Environmental Research

Commonly referred to as soot, black carbon (BC) is a primary aerosol emitted from incomplete combustion of organic materials such as fossil fuels, biofuels and biomass. BC aerosolis a dominant anthropogenic solar radiation absorber, absorbing approximately 1 million times more radiation per unit of mass than CO2. Recent research has found that BC is the second largest anthropogenic contributor to global warming. BC aerosol is not only a short-lived climate forcer (SLCF) but also an air pollutant that adversely affects human health. Emission sources of BC aerosol are mainly residential, industrial, transportation related and/or and open burning sources. In a …

Self-Reliance Beyond Neoliberalism: Rethinking Autonomy At The Edges Of Empire, Karen Hébert, Diana Mincyte

Publications and Research

Across scholarly and popular accounts, self-reliance is often interpreted as either the embodiment of individual entrepreneurialism, as celebrated by neoliberal designs, or the basis for communitarian localism, increasingly imagined as central to environmental and social sustainability. In both cases, self-reliance is framed as an antidote to the failures of larger state institutions or market economies. This paper offers a different framework for understanding self-reliance by linking insights drawn from agrarian studies to current debates on alternative economies. Through an examination of the social worlds of semisubsistence producers in peripheral zones in the Global North, we show how everyday forms of …

Modeling Black Bear Population Dynamics In A Human-Dominated Stochastic Environment, David L. Lewis, Stewart W. Breck, Kenneth R. Wilson, Colleen T. Webb

United States Department of Agriculture Wildlife Services: Staff Publications

Many large carnivore populations exist in human-influenced stochastic environments where availability of natural food sources vary annually and anthropogenic food sources can supplement energetic demands, but at a potential demographic cost due to human–wildlife conflict and subsequent conflict management. Understanding how these competing factors influence a population is complex and difficult to study, but here we demonstrate the utility of using a stochastic projection matrix model and perturbation analysis to gain insight into this problem. We modeled a black bear population subjected to stochastic failures of fruiting and masting species, but with access to garbage in urban environments.We parameratized our …

Science-Fictional North Korea: A Defective History, Seo-Young J. Chu

Publications and Research

Kafkaesque, Orwellian, eerie, surreal, bizarre, grotesque, alien, wacky, fascinating, dystopian, illusive, theatrical, antic, haunting, apocalyptic: these are just a few of the vaguely science-fictional adjectives that are now associated with North Korea. At the same time, North Korea has become an oddly convenient trope for a certain aesthetic – an uncanny opacity; an ominous mystique – that many writers and artists have exploited to generate striking science-fictional effects in texts with little or no connection to North Korean reality. (The 2002 Bond film Die another Day, for example, draws from North Korea’s science-fictional aura to animate North Korean super-villains who …

Celebrating Extinction? The Disconnect Between Reality And Media Representation Of Bluefin Tuna In Japan, Gene Fukui

Honors Papers

The Japanese media has perpetually glorified Bluefin tuna as the symbol of Japanese culture, cuisine, and national identity. Meanwhile, Bluefin tuna stocks are plummeting due to overfishing, and some species are international recognized as endangered. Blame is primarily placed on Japan, as the nation consumes 80% of Bluefin in the world and the government has admitted to overfishing several times. This has led to international environmental organizations and Western governments continually criticizing Japan for its unsustainable fishing practices.

This paper provides an explanation as to why there is no domestic movement within Japan to put an end to overfishing: the …

Photo-Identification Methods Reveal Seasonal And Long-Term Site-Fidelity Of Risso’S Dolphins (Grampus Griseus) In Shallow Waters (Cardigan Bay, Wales), Marijke N. De Boer, Josephine Clark, Mardik F. Leopold, Mark P. Simmonds, Peter J.H. Reijnders

Ecology Collection

A photo-identification study on Risso’s dolphins was carried out off Bardsey Island in Wales (July to September, 1997-2007). Their local abundance was estimated using two different analytical techniques: 1) mark-recapture of well-marked dolphins using a “closed-population” model; and 2) a census technique based on the total number of iden-tified individual dolphins sighted over the study period. The mark-recapture estimates of 121 (left sides; 64 - 178, 95% CI; CV 0.24) and 145 dolphins (right sides; 78 - 213, 95% CI; CV 0.24) closely matched the census technique estimates (population size of 90 - 151). It was found that the dolphins …

Institutionalizing Harm In Tennessee: The Right Of The People To Hunt And Fish, Lois Presser, Jennifer L. Schally

The Journal of Sociology & Social Welfare

What discourses render harm to nonhumans a right? In this article we consider the case of Tennessee's Senate Joint Resolution 30, which proposed to grant citizens "the personal right to hunt and fish." To clarify the institutional logics legitimizing such harm, we analyzed the text of the Resolution as well as statements by politicians and others leading up to the passage of the amendment the Resolution would enact. Logics that supported the Resolution were: (1) claims of the economic utility of hunting and fishing; (2) veneration of the past; and (3) claims of future infringement on said activities. Nonhuman targets …

An Experimental And Computational Evaluation Of The Importance Of Molecular Diffusion In Gas Gravity Currents, Jeremy Jac Herman

Graduate Theses and Dissertations

The accidental release of hazardous, denser-than-air gases during their transport or manufacture is a vital area of study for process safety researchers. This project examines the importance of molecular diffusion on the developing concentration field of a gas gravity current released into a calm environment. Questions which arose from the unexpectedly severe explosion in 2005 at Buncefield, England were of particular interest. The accidental overfilling of a large tank with gasoline on a completely calm morning led to a massive open air explosion. Forensic evidence showed that at the time of ignition, a vapor cloud, most of which now appears …

Environmental Beliefs And Concern About Animal Welfare: Exploring The Connections, Catherine A. Faver

The Journal of Sociology & Social Welfare

An online survey examined environmental beliefs and concern about animal welfare among 105 social work students in the U.S.- Mexico border region. Environmental beliefs were measured using items from the revised New Ecological Paradigm (NEP) Scale (Dunlap, Van Liere, Mertig, & Jones, 2000). Higher concern about animal welfare was significantly related to three dimensions of the revised NEP Scale: (1) belief in the fragility of nature's balance, (2) belief in the possibility ofan ecological crisis, and (3) rejection of the notion that humans have a right to dominate nature (anti-anthropocentrism). The findings suggest that by making explicit connections between the …

Gathering "Wild" Food In The City: Rethinking The Role Of Foraging In Urban Ecosystem Planning And Management, Rebecca J. Mclain, Patrick T. Hurley, Marla R. Emery, Melissa R. Poe

Environment and Sustainability Faculty Publications

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, …

Food Sovereignty: An Alternative Paradigm For Poverty Reduction And Biodiversity Conservation In Latin America, M Jahi Chappell, Hannah Wittman, Christopher M. Bacon, Bruce G. Ferguson, Luis García Barrios, Raúl García Barrios, Daniel Jaffee, Jefferson Lima, V. Ernesto Méndez,, Helda Morales, Lorena Soto-Pinto, John Vandermeer, Ivette Perfecto

Environmental Studies and Sciences

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …

Transitional Justice: Prioritizing Truth Commissions Or International Tribunals To Ensure Healing And Reconciliation, Jlateh Vincent Jappah, Danielle Taana Smith

Journal of International and Global Studies

There is a recent increased examination of the effects of international funding for truth commissions and criminal tribunals in post-conflict societies as they transition to peace. The discourse on whether to prioritize truth commissions or international criminal tribunals and which form of transitional justice more effectively fosters healing and reconciliation continues to be highly polemical. This paper explores whether, in terms of post-conflict healing and reconciliation, international funding would be better spent on truth commissions than on international criminal tribunals or vice versa. It examines the complexities and heterogeneity of transitional societies and suggests that international funding for transitional justice …

Developing Paradise: Tourism, The Local Community, And Nature In Las Terrenas, Dominican Republic, John Ripton Ph.D.

Journal of International and Global Studies

Las Terrenas, a town in the Samanà province of the Dominican Republic, has experienced phenomenal growth of its tourist industry. Electricity only arrived in Las Terrenas in the late 1990s, yet today, more than 70 hotels and other establishments offer thousands of rooms in tourist accommodations. In little more than two decades, the population of Las Terrenas has mushroomed from a few hundred to nearly 20,000. While the forces of commercial development integrate Las Terrenas into the global economy, its municipal infrastructure simply has not kept pace. The national government finances the construction of roads and other projects to promote …

Transnational Policy Networks In Global Water Governance In India, Vandana Asthana Ph.D.

Journal of International and Global Studies

This paper argues that in the processes of global water governance, transnational policy networks play a significant role in defining spaces of engagement that privilege certain voices and versions. These networks produce narratives that not only convey storylines of sustainable water practices but also often have embedded within them the advocacy of a particular policy instrument that they intend to promote. What appears as knowledge is often structured towards the goal at which it is directed. Using application of private sector participation in water as an example from India, the paper explores how these power/knowledge regimes are established and supported …
