An Agent Based Model Of Climate Change And Conflict Among Pastoralists In East Africa, Atesmachew B. Hailegiorgis, William G. Kennedy, Mark Rouleau, Jeffrey K. Bassett, Mark Coletti, Gabriel C. Balan, Tim Gulden

International Congress on Environmental Modelling and Software

We present an agent-based model of human-environment interaction and conflict in East Africa using the MASON agent-based simulation environment. Our model focuses on the complex interaction of pastoral groups with their environment and other emerging external actors. Our model supports the observation that increased seasonal rainfall variability and droughts create tremendous stress on pastoralists groups and challenges their long-term resilience and adaptive response mechanisms.

Estimates Of Seasonal Methane Emissions From Paddy-Rice Cropped At Pindamonhangaba Municipality, Brazil, Using Dndc Model, Maria Conceição Peres Young Pessoa, Magda Aparecida De Lima, Omar Vieira Vilella

International Congress on Environmental Modelling and Software

Agricultural activities have been pointed out as one of anthropogenic sources of greenhouse gas emissions, which influence on climatic changes. Information available at Intergovernmental Panel on Climatic Changes (Ipcc) indicated that methane emissions (CH4) generated during the paddy-rice culture development phases is one of these activities and must be better investigated at field conditions. Computer tools that allow following the space-time dynamic of methane emissions from paddy-rice culture, considering the management involved, should also contribute to identify alternatives in order to minimize the high emission rates. Thereby, the Denitrification-Decomposition model (DnDc) can be used to investigate alternative scenarios in order …

Phytoplankton carbon, measured by microscopy, averaged 314 ± 251 μg C L^-1 and ranged from 115 to 936 μg C L^-1. Microzooplankton ingestion rates averaged 303 ± 260 μg C L^-1d^-1 and ranged from 90 to 907 μg C L^-1d^-1. …

Gender And Antiretroviral Drug Effects On The Hive-Self Efficacy And Health Locus Of Control Of Patients Living With Hive/Aids, Bola Ogunyemi, Okwuazu Udonadi

Academic Leadership: The Online Journal (2003-2012)

The HIV-AIDS epidemic is perhaps one of the greatest challenges to countries of the world today. Since it was first diagnosed in 1981, it has become a significant threat to everybody throughout the world irrespective of gender and sexual orientation. The widespread of the disease especially in the African continent has become a major source of concern to government and non-governmental agencies and others concerned with curtailing the pandemic disease. In fact in hard hit areas of Africa, infection rate has been higher in teenage groups than that of adult (Hopkins, 2000). In 2008 alone, an estimated 3 million people …

Evidence For A Change In The Rate Of Aging Of Osteological Indicators In American Documented Skeletal Samples, Wendy Elizabeth Potter

Anthropology ETDs

The question of uniformity in skeletal age changes across populations is fundamental to all comparative work in skeletal biology. Whether an aging standard will work on target groups that differ in time, space, and background from the reference sample is essential for reliable, accurate age estimation. This research addressed whether a difference in skeletal senescence exists between older American documented collections and more recent ones. The pubic symphysis, auricular surface, sternal rib end, and suture obliteration were scored for a sample of American Blacks and Whites drawn from the Terry, Hamann-Todd, Bass Documented, Maxwell Museum, and Maricopa County Forensic Science …

Social Shopping Using Food Spimes, Timothy Maciag, Daryl H. Hepting, Joann Jaffe, Katherine Arbuthnott, Darryl Dormuth

International Congress on Environmental Modelling and Software

Bruce Sterling defines spimes, in part, as extensively rich streams of data and informationabout things. From a theoretical viewpoint, the concept of spimes is indeed interesting,with seemingly endless possibilities for enriching our knowledge about the things all around us.In terms of our everyday decision-making activities, spimes could have significant influence onour behaviours, empowering us to make more informed choices. No where is this more true thanin topics relating to sustainability, especially in how sustainability relates to the selection of thefood that we eat. With vast amounts of information available, the issue of selecting good food canbe difficult and more adequate …

Modelling Irrigation Demand From Two Grasslands In Switzerland Under Contrasting Climatic Conditions And Soil Properties, P. C. Smith, P. Calanca, J. Fuhrer

International Congress on Environmental Modelling and Software

We examine irrigation demand in Switzerland under current climatic conditionson the basis of simulations with a process-based grassland model. Two sites are considered:Oensingen, on the Swiss Plateau, benefits from a humid climate and is rarely affected bydrought; Sion, located in the Rhone Valley, is highly water-limited, with critical soilmoisture conditions every year. Water requirements to sustain productivity therefore varysubstantially between the sites and in time, with needs up to 800 mm per year at Sion, andaverage needs of the order of 300 mm at Oensingen if a shallow soil is assumed. We showthat simple relations can be found between water …

Environmental Flow Requirements (Efrs) Related To Preference Of Phytoplankton In The Yellow River Estuary (Yre) Based On An Ecohydrodynamic Model, R. Zhao, Z. F. Yang, T. Sun

International Congress on Environmental Modelling and Software

The response of ecological processes to hydrological processes is a critical issue in the assessment of environmental flow requirements in estuaries. Considering its representative function of the primary productivity in estuaries, the phytoplankton community was selected as the bioindicator to indicate the variation of ecosystems influenced by hydrological processes in estuaries. Based on the regression analysis, a response relation model was established for describing the relationship between characteristics of phytoplankton communities (chlorophyll a, Fucoxanthin, chlorophyll b, and pyridinin) and indicating factors including salinity, COD, ammonia nitrogen, and dissolved oxygen. The biomass objective of high nutritional level organisms, the biomass of …

Soil Total Organic Carbon, Δ13c Values And Their Responses To The Soil Core Transferring Experiment From High- To Low-Elevation Forest Along Natural Altitudinal Transect Of Old Temperate Volcanic Forest Soils, Zhang Xin-Yu, Meng Xian-Jing, Fan Jin-Juan, Gao Lu-Peng, Sun Xiao-Min

International Congress on Environmental Modelling and Software

In this study, the responses of soil organic carbon and δ13C values to soil warming were conducted by relocating intact soil cores from high- to low-elevation forests for one year along a natural altitudinal transect in the northern slope of Changbai Mountain. As expected, the soil-core relocation caused significant increase in soil temperature but made no significant effect on soil moisture. The results showed that after one year incubation, soil relocation significantly decreased TOC contents, and δ13C decreased. Pearson correlation analysis demonstrates that TOC content was negatively related to soil temperature but positively related to soil moisture. After one-year simulated …

Exploring The Choice Of Decision Making Method In An Agent Based Model Of Land Use Change, A. R. Cabrera, P. J. Deadman, E. S. Brondizio, M. Pinedo-Vasquez

International Congress on Environmental Modelling and Software

In agent-based models of land use/cover change (ABM/LUCC), small changes in micro-level decision-making methods used by agents may significantly affect macro-level outcomes. Yet, the implications of choosing a specific decision making model are seldom explored in ABM/LUCC studies. This paper discusses an ABM/LUCC modelling study of smallholder farming households in the Amazonian varzea in Maraj´o Island, Brazil. These agents represent the 21 households within the community of Paricatuba. Farmers in this community cultivate acai as a primary source of income, in addition to other farming and economic activities such as offsite employment. In the model, agents make annual decisions to …

Cmls94 Trends On Water Risk Contamination By Pesticide At Two Field Crops Over Areas Of Aquifers At Amazon And Southeast Regions, Brazil, Maria Conceição Peres Young Pessoa, Ricardo De Oliveira Figueiredo, Sonia Claudia Nascimento De Queiroz, Marco Antonio Ferreira Gomes, Anderson Soares Pereira, Eduardo Jorge Maklouf Carvalho, Vera Lucia Ferracini, Manoel Dornelas De Souza, Lilianne Maia Lima, Fábio Monteiro Cruz

International Congress on Environmental Modelling and Software

The absence of strategies for sustainable use and management of hydric resources is probably the main reason of several negative environmental impacts. Among them we can point out the inadequate use of pesticides on crop fields located over vulnerable areas. Due to this, the assessment of water risk contamination potential in aquifers has extreme importance to drive practices in order to reduce undesirable contaminations. In the present work we use CMLS-94 simulator to evaluate the vertical movement of pesticides through soils in agricultural catchments over areas of aquifers in Brazil. 2-4D acid, dimethoate, prochloraz, methamidophos and carbendazim applied in yellow …

Modelling Needs Assessment For Social Adaptation To Climate Change In Siberia, G. A. Alexandrov, G. Inoue, T. Matsunaga

International Congress on Environmental Modelling and Software

Despite the common expectation that climate change may make Siberia a warm heaven, this would not be good for local people. Surprisingly the people of Siberia do rely on the winter cold. Warming may be a serious challenge here. Climate change threatens Siberian forests, lakes and permafrost. In the region where landscapes are unstable this implies the risks of losing the traditional means of subsistence, at least for a while. Social adaptation to climate change is becoming an urgent issue, as the first signs of warming are becoming noticeable to local people. This article reports an attempt to explore the …

Co-Varying Patterns Of Physical Activity And Sedentary Behaviors And Their Long-Term Maintenance Among Adolescents, Jihong Liu, Jinseok Kim, Natalie Colabianchi, Andrew Ortaglia, Russell R. Pate

Faculty Publications

Background: We examined the covarying patterns of physical activity and sedentary behaviors among adolescents and their long-term maintenance. Methods: Data came from the National Longitudinal Study of Adolescent Health (1995-2002). We used latent class analysis to identify distinct covarying patterns in adolescence. Logistic regression models were used to predict odds of meeting moderate-to-vigorous physical activity (MVPA) recommendations (≥5 bouts/week) and exceeding screen time guidelines (>2 hours/day) 6 years later based on their adolescent class profile. Results: Five classes for each gender were identified and labeled as low physical activity (PA)/low sedentary behaviors (SED), moderate (Mod) PA/high (HI) SED, Mod …
