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 …


A Dynamic Model Of Primary Production And Plant Coverage In An Oligotrophic Tropical River, Barbara J. Robson Jul 2010

A Dynamic Model Of Primary Production And Plant Coverage In An Oligotrophic Tropical River, Barbara J. Robson

International Congress on Environmental Modelling and Software

Many of Australia's tropical rivers are amongst the most ecologically intact inthe world, but have been relatively little studied. Now, however, there is pressure forfurther development of these tropical land and water resources. To avoid repeatingmanagement mistakes that have been made elsewhere, it is essential to improve ourunderstanding of how these rivers function. As part of the Tropical Rivers and CoastalKnowledge Research hub, we studied flow, nutrients, and primary production in the DalyRiver (N.T.), a perennial tropical river maintained in the dry season by ground-water anddeveloped a dynamic simulation model to predict the coverage and biomass of each of fivekey …

These place-based comparisons are vital in agricultural systemsdue to the increasing global demand for food production, coupled with the realization thatthis should be achieved with minimal negative impact on the environment. The farm is thelogical unit of management in agricultural systems and hence there is a need for ecosystemtradeoff assessments at the farm scale. We have carried out a literature review of thetradeoffs in the …


Risk Management In An Uncertain Environment - A Study From Semi-Arid Grazing Systems, O. Jakoby, M. F. Quaas, Birgit Müller, Karin Frank Jul 2010

Risk Management In An Uncertain Environment - A Study From Semi-Arid Grazing Systems, O. Jakoby, M. F. Quaas, Birgit Müller, Karin Frank

International Congress on Environmental Modelling and Software

Since livestock grazing is the most important type of land-use in arid and semi-arid rangelands with uncertain and highly variable climatic conditions, well adapted grazing strategies are crucial for effective risk management. However, local environmental characteristics and individual needs and perception lead to a broad range of different management forms used in practice. In this paper we (i) analyse how uncertain climate conditions and the individual farmer’s characteristics like risk aversion, economic constraints and effort cost affect the choice of management, (ii) evaluate the viability of different management options, and in particular (iii) their robustness under climate variability. We use …

Development Of An Agent Based Coupled Economic And Hydrological Model Of The Deep Creek Watershed In British Columbia, Canada., John Janmaat, Markandu Anputhas

International Congress on Environmental Modelling and Software

Deep Creek is an important tributary of the Okanagan River system in Southern British Columbia. The creek drains a watershed with sediments deposited by multiple glacial events, resulting in a complex pattern of surface and groundwater connections throughout the basin. Further, the basin is experiencing changes in agricultural enterprises as well as population growth, and may be heavily impacted by climate change. The MIKE SHE integrated hydrological modeling system is being used to develop a model of the basin hydrology. The watershed is relatively small – with only a couple of hundred agricultural water users – lending itself to a …

Since the resources from environment are in short supply, it is necessary to alleviate the conflict between high-speed economic construction and limited resources in the Chinese society. This paper aims to analysis the variation of natural resources input into China during 2000-2007 based on extended exergy as an eco-centric metric. With the materials, labor, capital and environmental renovation quantified by exergy numeraire grounding on the second-law metric in view of ecological accounting, the composition and proportion of extended exergy clearly revealed the whole condition of available energy input into society in China. Moreover, two indexes, i.e., extended exergy consumption intensity …


Agent Based Modelling Of Caribou Environmental Interactions In The Canadian Arctic, Glen Lesins, Kaz Higuchi Jul 2010

Agent Based Modelling Of Caribou Environmental Interactions In The Canadian Arctic, Glen Lesins, Kaz Higuchi

International Congress on Environmental Modelling and Software

Agent or individual based modelling (IBM) is recognized as an important tool in biological modelling for simulating animal behaviour and interactions with the environment at the level of the individual while maintaining a collective perspective. The method allows rules to be programmed for the interactions between like and unlike species, responses to geographic factors and impacts from human activities. By emphasizing the development of appropriate rules for the individual, one can avoid imposing ad hoc assumptions concerning the population as a whole and instead allow emergent phenomena to unfold at the larger scale. Here we report on preliminary results using …

Evaluating The Impact Of Climate Change On Global Hpai H5n1 Outbreaks, Zhijie Zhang, Dongmei Chen, Wenbao Liu, Lei Wang

International Congress on Environmental Modelling and Software

Highly pathogenic avian influenza viruses H5N1 have spread throughout Asia, Europe, and Africa in the past decade, raising serious worldwide concerns about a potential new pandemic. Many studies have investigated the spread of the HPAI H5N1 virus and discussed its possible risk factors. However, the climate factor, which can affect the whole process of H5N1 outbreaks, has been greatly ignored. The objective of this preliminary study is to use a GIS-based approach to explore the potential impacts of temperature change on H5N1 outbreaks. We have divided the outbreaks into five epidemic waves. Although the temperature ranges of different epidemic waves …


Unexpected Side-Effects Of Winter Feeding: Learning From Mahalanobis Distances Factor Analysis In The Case Of Red-Crowned Cranes In Hokkaido, Japan, Yi-Liang Kuo Jul 2010

Unexpected Side-Effects Of Winter Feeding: Learning From Mahalanobis Distances Factor Analysis In The Case Of Red-Crowned Cranes In Hokkaido, Japan, Yi-Liang Kuo

International Congress on Environmental Modelling and Software

Winter feeding has become a critical approach to sustain animals in high latitude,but little literature has investigated possible side-effects in terms of ecological niches. Toexplore whether winter feeding might affect species distributions at regional scale, weemployed a novel spatial model, Mahalanobis Distances Factor Analysis, in the case ofRed-crowned Cranes (Grus japonensis) in Hokkaido, Japan. This model features betterprediction ability with more explicit ecological significance compared to conventionalmethods. Furthermore, particularly innovative is that axes are used to define ecologicalniches, with a minimal set of habitual variables to calculate habitat suitability in thealgorithm. In results, winter feeding seemed to considerably impact the …


Decision Support For Environmental Monitoring And Restoration: Application Of The Partially Observable Markov Decision Process, David Tomberlin Jul 2010

Decision Support For Environmental Monitoring And Restoration: Application Of The Partially Observable Markov Decision Process, David Tomberlin

International Congress on Environmental Modelling and Software

Environmental monitoring programs can improve management over time, butgenerally require that correspondingly less time and money be put into direct restorationefforts such as revegetation or dam removal. Thus, budget constraints compelenvironmental managers to make difficult decisions regarding the allocation of scarcefunds and personnel between environmental monitoring and environmental restoration.Among other factors, the best allocation of resources between monitoring and restoration—or, more generally, learning and doing—will depend on the quality of information availablefrom a monitoring program. This paper demonstrates the application of the partiallyobservable Markov decision process (POMDP) as a framework for investigating theoptimal intensity of monitoring given stochastic state dynamics …


Modeling For Uncertainty Assessment In Human Health Risk Quantification: A Fuzzy Based Approach, Abdullah Mofarrah, Tahir Husain Jul 2010

Modeling For Uncertainty Assessment In Human Health Risk Quantification: A Fuzzy Based Approach, Abdullah Mofarrah, Tahir Husain

International Congress on Environmental Modelling and Software

Health risk analysis to the contaminated water involves the use of mechanisticmodels that include many uncertain and variable parameters. Currently, the uncertainties ofrisk analysis models are treated using statistical theories considering the randomness in datadistribution. However, not all uncertainties in data or model parameters are due torandomness. Other sources of imprecision that may lead to uncertainty include scarce orincomplete data, measurement error or subjective interpretation of available information.These kinds of uncertainties cannot be treated solely by statistical methods. This paper usesfuzzy set theory (FST) together with probability theory (PT) to incorporate uncertaintiesinto risk analysis model. Based on the form of …

From Landscape-Scale Models Of Forest Biodiversity Change Towards An Integrated Planning Tool – A Gui For Building Empirical Ecological Extrapolation Models Based On Land Cover Data –, Tobias Lung, Gertrud Schaab

International Congress on Environmental Modelling and Software

Spatially explicit models linking biological field data with remotely-sensed landcover data have become commonplace for landscape-scale biodiversity assessments, butthey usually neither consider time series data nor include future scenarios. Extrapolationmodels addressing these deficiencies for three keystone species/groups of the Kakamega-Nandi forests in western Kenya proved to be a suitable means for investigating the effectsof long-term land change processes on the development of forest biodiversity in space andtime. However, the experimental modelling design of the approaches is not consideredconvenient for a more comprehensive, interlinked assessment including morespecies/groups and also ecosystem functions and services, nor is it adequate for a stronglocal stakeholder …

Habitat Models As A Research Gap In Biodiversity Conservation In Tropical Rain Forest Of Southeast Asia, Mona Nazeri, Jusoff Kamaruzzaman, Nima Madani

International Congress on Environmental Modelling and Software

Tropical rain forests, the richest terrestrial ecosystem on earth are disappearing due to land use changes mainly agricultural activities and timber logging. Habitat alteration and as a result fragmentation have direct effect on species survival trough lose of connectivity between suitable habitats. Without a doubt the traditional strategies for protecting different wildlife species in this region was not successful enough to guarantee the survival of remaining biodiversity. Distribution modelling which, very little has been studied in the region, is significantly important for biodiversity conservation programs. Distribution data can determine all the areas that can have high potential of occupancy by …


Qualitative Reasoning In Participatory Spatial Planning: The Use Of Osiris In The Yellow River Delta, P. J. F. M. Verweij, M. Van Eupen, J. Roos-Klein Lankhorst, W. Nieuwenhuizen Jul 2010

Qualitative Reasoning In Participatory Spatial Planning: The Use Of Osiris In The Yellow River Delta, P. J. F. M. Verweij, M. Van Eupen, J. Roos-Klein Lankhorst, W. Nieuwenhuizen

International Congress on Environmental Modelling and Software

Societies see the emergence of new governance concepts, based on the assumption that processes of planning and decision taking are no longer hierarchical but the product of complex interactions between governmental and nongovernmental organizations, and the general public (the model of ‘co-production of knowledge’; Callon, 1999). All involved are seeking to influence the collectively binding decisions that have consequences for their interests. To account for this changing governance and the increased number of stakeholders involved, decisions need to be assessed in an integrated context. This paper discusses the OSIRIS modeling environment for knowledge rule based reasoning on spatial information. The …


Modelling The Complexity Of The Cropping Plan Decision-Making, J. Dury, F. Garcia, Arnaud Reynaud, O. Thérond, Jacques-Eric Bergez Jul 2010

Modelling The Complexity Of The Cropping Plan Decision-Making, J. Dury, F. Garcia, Arnaud Reynaud, O. Thérond, Jacques-Eric Bergez

International Congress on Environmental Modelling and Software

Every year farmers have to allocate their fields to different crops and crop management. These choices depend on multiple spatial and temporal factors, farmers’ strategy and risk behaviour. To support farmers in these complex decisions and efficiently allocate scarce resources, we studied cropping plan decisions in arable farms with the aim of simulating contextual changes. A deeper understanding of these processes at farm level is then a start to model and design flexible and environmental-friendly cropping systems. We propose a stepwise approach to study and formalize the complexity of the decision-making processes based on farmer’s interviews and on modelling approach …


Interacting Environmental Interfaces: Synchronization In Substance Exchange Between Environmental Interfaces Regarded As Biophysical Complex Systems, Dragutin T. Mihailović, M. Budincevic, D. Perisic, Igor Balaž, A. Firanj Jul 2010

Interacting Environmental Interfaces: Synchronization In Substance Exchange Between Environmental Interfaces Regarded As Biophysical Complex Systems, Dragutin T. Mihailović, M. Budincevic, D. Perisic, Igor Balaž, A. Firanj

International Congress on Environmental Modelling and Software

In modeling environmental interfaces regarded as biophysical complex systems, one of the main tasks is to create an operative interface with the external environment. The interface should provide a robust and prompt translation of the vast diversity of external physical and/or chemical changes into a set of signals that are understandable for a biophysical entity. Although the organization of any system is of crucial importance for its functioning, it should not be forgotten that in biophysical systems we deal with real-life problems where a number of other conditions must be satisfied in order to put the system to work. One …

Alexander Korda And His "Foreignized Translation" Of The Thief Of Bagdad (1940), Jessica Caroline Alder Wiest Jul 2010

Alexander Korda And His "Foreignized Translation" Of The Thief Of Bagdad (1940), Jessica Caroline Alder Wiest

Theses and Dissertations

Adaptation studies has recently turned an eye towards translation theory for valuable discussion on the role of movie makers as translators. Such discussion notes the difficulties inherent in adapting a medium such as a book, a play, or even a theme park ride into film. These difficulties have interesting parallels to the translation of one language into another. Translation theory, in fact, can shed important light on the adaptation process. Intrinsic to translation theory is the dichotomy between domesticating translation and foreignizing translation, the two major styles of translation. Translation scholar Lawrence Venuti, the author of these two terms, argues …


Chemopreventive Effects Of Dietary Selenium And Soy Isoflavones In A Mouse Model Of Prostate Cancer, Trevor Elisha Quiner Jun 2010

Chemopreventive Effects Of Dietary Selenium And Soy Isoflavones In A Mouse Model Of Prostate Cancer, Trevor Elisha Quiner

Theses and Dissertations

Prostate cancer is the most commonly diagnosed non-skin cancer in men and the second leading cause of cancer death in the United States. Prostate cancer, like many cancers, is a disease that generally requires a long period of time to develop and grow before it becomes detectable. This long period of latency makes prostate cancer a candidate for dietary chemoprevention. Soy and selenium (Se), are associated with a decreased risk of prostate cancer. We previously showed that high dietary intake of selenium (Se) and soy isoflavones decreased the expression of the androgen receptor (AR) and AR-regulated genes in the prostates …


Liver Kinase B1/Amp-Activated Protein Kinase Signaling In The Diaphragm, Jacob D. Brown Jun 2010

Liver Kinase B1/Amp-Activated Protein Kinase Signaling In The Diaphragm, Jacob D. Brown

Theses and Dissertations

The Liver Kinase B1 (LKB1)/AMP-Activated Protein Kinase (AMPK) signaling pathway is a major regulator of skeletal muscle metabolic processes. During exercise, LKB1-mediated phosphorylation of AMPK leads to its activation, promoting mitochondrial biogenesis and glucose transport, among other effects. The roles of LKB1 and AMPK have not been fully characterized in the diaphragm. Two methods of AMPK activation were used to characterize LKB1/AMPK signaling in diaphragms from muscle-specific LKB1 knockout (KO) and littermate control (C) mice: (1) acute injection of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) and (2) 5-min direct electrical stimulation (ES) of the diaphragm. Diaphragms were excised 60 minutes post-AICAR injection and …


Burke, Dewey, And The Experience Of Aristotle's Epideictic: An Examination Of Rhetorical Elements Found In The Funerals Of Lincoln, Kennedy, And Reagan, Xanthe Kristine Allen Farnworth Jun 2010

Burke, Dewey, And The Experience Of Aristotle's Epideictic: An Examination Of Rhetorical Elements Found In The Funerals Of Lincoln, Kennedy, And Reagan, Xanthe Kristine Allen Farnworth

Theses and Dissertations

This article examines the role of epideictic rhetoric as a tool for promoting civic virtue in the public realm through the application of Kenneth Burke's theory of identification and John Dewey's explanation of an aesthetic experience. Long the jurisdiction of Aristotle's logical arguments, civic discussion usually works within the realm of forensic or deliberative persuasion. However, scholarship in the last fifty years suggests there is an unexplored dimension of Aristotle's discussion of epideictic and emotion that needs to be examined in an attempt to identify its usefulness as a tool for examining human experience and practical behavior in the political …


Targeting Complex Cyclic Peptides For Synthesis: The Celogentin And Theonellamide Families, Joshua Wayne Robinson Jun 2010

Targeting Complex Cyclic Peptides For Synthesis: The Celogentin And Theonellamide Families, Joshua Wayne Robinson

Theses and Dissertations

Celogentin C and theonellamide F are a class of natural products that have potential antimitotic behavior. They both contain interesting bicyclic structures with unusual linkages within a central moiety. Celogentin C's highly functionalized tryptophan moiety has two unusual linkages, a β-substituted Leu connection to the C6 of the indole structure that makes up the left-hand ring, and a τ-N connection of the imidazole to the C2 of the indole constructing the right-hand ring. This right-hand ring connection was solved via a novel oxidative coupling procedure developed in our group and the left-hand ring was initially constructed via a radical conjugated …
