[1] Carbon flux models based on light use efficiency (LUE), such as the MOD17 algorithm, have proved difficult to parameterize because of uncertainties in the LUE term, which is usually estimated from meteorological variables available only at large spatial scales. In search of simpler models based entirely on remote‐sensing data, we examined direct relationships between the enhanced vegetation index (EVI) and gross primary productivity (GPP) measured at nine eddy covariance flux tower sites across North America. When data from the winter period of inactive photosynthesis were excluded, the overall relationship between EVI and tower GPP was better than that between …

On-Line Electronic Document Collaboration And Annotation, Trev R. Harmon

Theses and Dissertations

The Internet provides a powerful medium for communication and collaboration. The ability one has to connect and interact with web-based tools from anywhere in the world makes the Internet ideal for such tasks. However, the lack of native tools can be a hindrance when deploying collaborative initiatives, as many current projects require specialized software in order to operate. This thesis demonstrates, with the comparably recent advances in browser technology and Document Object Model (DOM) implementation, a web-based collaborative annotation system can be developed that can be accessed by a user through a standards-compliant web browser. Such a system, demonstrated to …

Human-Nonhuman Primate Interconnections And Their Relevance To Anthropology, Agustin Fuentes

Ecological and Environmental Anthropology (University of Georgia)

The human-nonhuman primate interface is a core component in conservation and an emerging area of discourse across anthropology. There is a growing recognition of the relevance of long-term sympatry between human and nonhuman primates. Until recently these relationships received limited attention in the anthropological literature and in the primatological construction of models for the behavior and evolution of primate societies. Most socioecological investigations into primate groups and human populations do not incorporate their interactions (beyond predation or crop raiding), potential pathogen sharing, or the role of the anthropogenically impacted environment. Current relationships between humans and nonhuman primates are generally assumed …

Ethnoprimatology: Toward Reconciliation Of Biological And Cultural Anthropology, Erin P. Riley

Ecological and Environmental Anthropology (University of Georgia)

One of the hallmarks of the discipline of anthropology is its holistic approach to the study of what it means to be human. A perennial challenge to the discipline, however, is the question of whether biological and cultural anthropology can truly coexist given their traditionally disparate epistemologies and methodologies. In this paper, I argue that the emerging field of ethnoprimatology, which focuses on the ecological and cultural interconnections between human and nonhuman primates, has real potential to bridge these two subfields. I support my argument by discussing the theoretical rationale of an ethnoprimatological approach with regard to the notion of …

Research Collection School Of Computing and Information Systems

This paper describes a pilot study on Wiki-G-Portal, a project integrating Wikipedia, an online encyclopedia, into G-Portal, a Web-based digital library, of geography resources. Initial findings from the pilot study seemed to suggest positive perceptions on usefulness and usability of Wiki-G-Portal, as well as subjects' attitude and intention to use.

Integration Of Wikipedia And A Geography Digital Library, Ee Peng Lim, Zhe Wang, Darwin Sadeli, Yuanyuan Li, Chew-Hung Chang, Kalyani Chatterjea, Dion Hoe-Lian Goh, Yin-Leng Theng, Jun Zhang, Aixin Sun

Research Collection School Of Computing and Information Systems

In this paper, we address the problem of integrating Wikipedia, an online encyclopedia, and G-Portal, a web-based digital library, in the geography domain. The integration facilitates the sharing of data and services between the two web applications that are of great value in learning. We first present an overall system architecture for supporting such an integration and address the metadata extraction problem associated with it. In metadata extraction, we focus on extracting and constructing metadata for geo-political regions namely cities and countries. Some empirical performance results will be presented. The paper will also describe the adaptations of G-Portal and Wikipedia …

Atmospheric Chemistry Of A 33–34 Hour Old Volcanic Cloud From Hekla Volcano (Iceland): Insights From Direct Sampling And The Application Of Chemical Box Modeling, William I. Rose, Genevieve A. Millard, Tamsin A. Mather, Donald E. Hunton, Bruce Anderson, Clive Oppenheimer, Brett F. Thornton, Terrence M. Gerlach, Albert A. Viggiano, Yutaka Kondo, Thomas M. Miller, John O. Ballenthin

Department of Geological and Mining Engineering and Sciences Publications

On 28 February 2000, a volcanic cloud from Hekla volcano, Iceland, was serendipitously sampled by a DC-8 research aircraft during the SAGE III Ozone Loss and Validation Experiment (SOLVE I). It was encountered at night at 10.4 km above sea level (in the lower stratosphere) and 33–34 hours after emission. The cloud is readily identified by abundant SO2 (≤1 ppmv), HCl (≤70 ppbv), HF (≤60 ppbv), and particles (which may have included fine silicate ash). We compare observed and modeled cloud compositions to understand its chemical evolution. Abundances of sulfur and halogen species indicate some oxidation of sulfur gases but …

Fire Making Fuel: How A Surface Fire In A Primary Forest Affected The Availability Of Potential Fuel One Year Later, Alex Leckie

Independent Study Project (ISP) Collection

Fires affect millions of hectares of tropical forests around the world. These fires result in great environmental damage and economical losses. Many farmers are dependent on fire for managing their lands and many times their fires accidentally spread into forests via fuels on the forest floor. This study attempted to analyze and quantify the difference of potential fuel in a primary forest which burned one year before and an unburned part of the same forest at a primary forest fragment surrounded by farms and with a history of anthropogenic accidental fires burning it. This was done by making three sample …

Antipodean Inscapes: Reflection Of The Land As A Young Man, Michael Kantor

Independent Study Project (ISP) Collection

The following paper contains a stand-alone piece of creative travel writing. ‘Cloud Juice’ is based on my interpretation of the experiences of the Fall 2006 Australia: Sustainability and the Environment semester. As it is my own personal interpretation it should not be placed in the category of non-fiction. Instead I have tried to write a story that presents the tone of my experience as honestly as possible, rather than simply telling the unbiased facts of the semester. My reason for writing this is to experiment with alternative methods of communicating the growth of an ecological ethic. By focusing on the …

Investigating The Feasibility Of A Passive Tracking Index For Monitoring Wildlife In The Lower Omo Valley, Ethiopia, Richard M. Engeman, Paul Evangilista

United States Department of Agriculture Wildlife Services: Staff Publications

In many places in Africa, constraints in human, financial and physical resources are common problems that limit the effectiveness of wildlife researchers and managers. In an attempt to identify a useful tool for monitoring African wildlife populations, we tested a passive tracking index (PTI) methodology on a unique wildlife resource area in the Lower Omo Valley, Ethiopia. The methodology had previously proved valuable for monitoring a wide variety of wildlife species, including ungulates and carnivores in North America and Australia. Two ungulates (lesser kudu and dikdik), a carnivore (hyena), a primate (baboon), and a ground foraging bird (guineafowl) were simultaneously …

A Rough Guide To Interdisciplinarity: Graduate Student Perspectives, Jessica K. Graybill, Sarah Dooling, Vivek Shandas, John Withey, Adrienne I. Greve, Gregory L. Simon

Institute for Sustainable Solutions Publications and Presentations

A widely held belief is that only through interdisciplinarity can academics effectively address today's complex ecological problems, because these problems demand cross-disciplinary efforts and specialized knowledge from natural and social scientists. Innovative interdisciplinary research and curricula have been created to train a new generation of scientists to engage with complex issues. It seems critical that those most affected by interdisciplinary education—doctoral students—provide feedback about such innovations. Without understanding students' experiences in interdisciplinary programs, faculty will not know whether they are "getting it right" for future generations of interdisciplinarians. From our experiences as doctoral students, we provide reflections and perspectives on …

Deep-Water Antipatharians: Proxies Of Environmental Change, B. Williams, M.J. Risk, S.W. Ross, K.J. Sulak

United States Geological Survey: Staff Publications

Deep-water (307–697 m) antipatharian (black coral) specimens were collected from the southeastern continental slope of the United States and the north-central Gulf of Mexico. The sclerochronology of the specimens indicates that skeletal growth takes place by formation of concentric coeval layers. We used 210Pb to estimate radial growth rate of two specimens, and to establish that they were several centuries old. Bands were delaminated in KOH and analyzed for carbon and nitrogen stable isotopes. Carbon values ranged from _16.4‰ to _15.7‰; the oldest specimen displayed the largest range in values. Nitrogen values ranged from 7.7‰ to 8.6‰. …

Customer Lifetime Value : An Integrated Data Mining Approach, Chen Xu

Lingnan Theses

Customer Lifetime Value (CLV) ---which is a measure of the profit generating potential, or value, of a customer---is increasingly being considered a touchstone for customer relationship management. As the guide and benchmark for Customer Relationship Management (CRM) applications, CLV analysis has received increasing attention from both the marketing practitioners and researchers from different domains. Furthermore, the central challenge in predicting CLV is the precise calculation of customer’s length of service (LOS). There are several statistical approaches for this problem and several researchers have used these approaches to perform survival analysis in different domains. However, classical survival analysis techniques like Kaplan-Meier …

Research On Synthetic Rope And Its Future In Timber Harvesting, Joel N. Hartter, Jared Leonard, John Garland, Steve Pilkerton

Geography

Steel wire rope is used for many logging applications. It has served the industry well in terms of strength, durability, and longevity. However, steel wire rope is difficult to use because it is stiff, heavy, and unyielding. These characteristics can lead to fatigue and exhaustion, and may contribute to worker injuries. Ultra-high molecular weight polyethylene synthetic rope has the potential to replace steel wire rope for selected logging applications. Research shows ergonomic gains and other operational effectiveness with its use. This paper presents research results, potentials, and issues in improving economic and ergonomic performance of ground-based and cable logging. Potential …

Climate Variability Has A Stabilizing Effect On The Coexistence Of Prairie Grasses, Peter B. Adler, Janneke Hille Ris Lambers, Phaedon C. Kyriakidis, Qingfeng Guan, Jonathan M. Levine

School of Natural Resources: Faculty Publications

How expected increases in climate variability will affect species diversity depends on the role of such variability in regulating the coexistence of competing species. Despite theory linking temporal environmental fluctuations with the maintenance of diversity, the importance of climate variability for stabilizing coexistence remains unknown because of a lack of appropriate long-term observations. Here, we analyze three decades of demographic data from a Kansas prairie to demonstrate that interannual climate variability promotes the coexistence of three common grass species. Specifically, we show that (i) the dynamics of the three species satisfy all requirements of ‘‘storage effect’’ theory based on recruitment …

Hydrochemistry In An Alpine Karst System, Sequoia And Kings Canyon National Parks, California, Joel Despain

Masters Theses & Specialist Projects

This study uses high-resolution, long-term conductivity, temperature, discharge, pH, and laboratory data from 2001 through 2003 from an alpine karst spring located at 2,500 m amsl in Sequoia National Park, California to reveal detailed chemical parameters of this karst system. The data show a system with a pronounced spring run-off, extended periods of base flow quiescence, storm responses tied to precipitation as rain or as snowfall, and clear diurnal and seasonal patterns of discharge. pH and spC values show an inverse relationship to discharge and temperature, which are generally in phase. Total inorganic carbon (TIC) and the fraction of mineral-derived …

Sustainability With Globalization: An Unsustainable Proposition, Daniel B. Reader

Masters Theses & Specialist Projects

Globalization is recognized as a world-encompassing phenomenon, even as its benefits are debated. Sustainability, the capacity to maintain high standards of living through generations, is at stake. This paper examines the problems of sustainability with globalization from several perspectives. High statistical correlation between indices of globalization and environmental degradation (r2 = 0.977, p < .001) is found using multi-dimensional scaling software. The socially destabilizing, culture flattening effects of globalization are examined, and the terms ‘nationalism’ and ‘terrorism’ are defined. On the basis of its medial position among the indices of both globalization and environmental degradation, Chile is explored in a case study of the interaction. Conclusions regarding Chile’s vulnerabilities are reached, and the country’s environmental, social, and economic ‘weak spots’ are identified. The ethical positions of globalization and sustainability are considered, and the conclusion that there is very little that can be done to alter the nature of the interaction is drawn. It is suggested that globalization minimizes the prospects of success in efforts toward sustainability by maximizing vulnerabilities among sustainability’s components.

Strategies For Reducing Mosquito-Borne Disease Vulnerability In Equine Populations: A Kentucky Case Study, Sara Dalton

Masters Theses & Specialist Projects

This research examined equine management practices that limit or contribute to the spread of West Nile virus and other mosquito-bome disease. I hypothesize that there is a relationship between equine management practices and outbreaks of mosquito-borne disease in horse populations. Improved and appropriate mosquito habitat management may limit the risk of mosquito-borne disease in humans and horses by helping to lower the mosquito populations. The study goals were to recognize equine management practices and mosquito prevention practices that foster outbreaks of mosquito-borne disease. This study used a questionnaire for county level analysis of equine management practices and the relationship to …

Geoexpert - An Expert System Based Framework For Data Quality In Spatial Databases, Aditya Kumar

Masters Theses & Specialist Projects

Usage of very large sets of historical spatial data in knowledge discovery process became a common trend, and in order to obtain better results from this knowledge discovery process the data should be of high quality. In this thesis we proposed a framework 'GeoExpert' for data quality assessment and cleansing tool for spatial data that integrates the spatial data visualization and analysis capabilities of the ARCGIS, the reason and inference capability of an expert system. In this thesis we implemented the proposed framework both stand-alone and web versions using ArcGIS Engine and ArcGIS Server, respectively. We used JESS expert system …

FEMA Flood Insurance Rate Map (FIRM) guidelines do not currently exist for conducting and incorporating tsunami hazard assessments that reflect the substantial advances in tsunami research achieved in the last two decades; this conclusion is the result of two FEMA-sponsored workshops and the associated Tsunami Focused Study (Chowdhury et al., 2005). Therefore, as part of FEMA's Map Modernization Program, a Tsunami Pilot Study was carried out in the Seaside/Gearhart, Oregon, area to develop an improved Probabilistic Tsunami Hazard Assessment (PTHA) methodology and to provide recommendations for improved tsunami hazard assessment guidelines. The Seaside area was chosen because it is typical …

A Swarm-Based Model For Increasing Impulse Shopping In Supermarkets, Zeehan-Ul-Hassan Usmani

Theses and Dissertations

In today's supermarket multi-billion dollar industry, impulse shopping accounts for 2 out of 3 purchases. The phenomenon is so prominent that some consider high levels of it to be a disorder in the same group as Pyromania (the impulse to burn things) and Kleptomania (the impulse to steal). Despite the current situation, most retail stores attempt to benefit from the fact that people are impulsive in nature as a way to maximize their profits. In order to improve on current levels of sales, retail stores and supermarkets need to look at out-of-the-box to solutions that may, at first, not appear …
