Service-Based Processing Of Modis Global Terrestrial Evapotranspiration Data For Hydrological Modelling, C. Siegert, S. Kralisch, A. Künne, D. Nüst, B. Proß, C. Stasch
International Congress on Environmental Modelling and Software
Current challenges of understanding and assessing the impacts of climate and land use changes on ecosystems worldwide demand for an ever increasing integration of data and process knowledge in environmental simulation models. While the growing performance of multi-processor computer environments and the availability of well-tested data products with global coverage provide the basis to address this demand, the seamless and automated pre-processing of existing information and their integration into environmental models often remains a crucial point. Here, Web Processing Services (WPS) can be used for an easily usable, standardized geo-information processing that links data with models. This work presents a …

Integrating Landscape Structure Into Participatory Bayesian Network Models Of Habitat Suitability, J. G. Froese, C. S. Smith, C. A. Mcalpine, P. A. Durr, R. D. Van Klinken
International Congress on Environmental Modelling and Software
Species distribution and habitat suitability models are widely used to inform decisions about conservation, resource or invasion management. Bayesian networks (BN) have received increasing attention in environmental modelling and habitat suitability modelling. Some important advantages of BNs are: a) they lend themselves to a participatory modelling framework including calibration from expert knowledge, explicit treatment of uncertain or missing knowledge and scenario analysis for decision support; b) they model responses specifically from interactions of influential habitat variables rather than statistical correlations; and c) recent advances have greatly simplified spatially-explicit applications (PMAT, https://github.com/DriesLanduyt/PMAT, QUICKScan, http://www.quickscan.pro or GeoNeticaTM, https://www.norsys.com). However, limited …

International Congress on Environmental Modelling and Software
Agricultural changes are complex and managing an appropriate type of crop change to satisfy stakeholders with various interests is challenging. Decisions regarding a crop change need to be debated among multiple stakeholders with various conflicting viewpoints. Two kinds of conflicts might occur as a result of crop change in an agricultural landscape: 1) conflicts among multiple ecosystem services i.e., internal conflicts and 2) conflicts among multiple stakeholders i.e., external conflicts. In this study, we held a series of meetings with stakeholders, who were experts in economics, energy, soil erosion, greenhouse gas emission, surface water, and biodiversity, to develop two crop …
‘Plain-View’ Earth System Simulation, Christian Neuwirth
‘Plain-View’ Earth System Simulation, Christian Neuwirth
International Congress on Environmental Modelling and Software
Hard-coded models of the earth system are typically perceived as ‘black boxes’, which are unserviceable by anyone other than those who developed the model. This constitutes a constraint to open innovation and cross-disciplinary model building. Likewise, the use of icon-based solutions is restricted by inappropriate performance on a larger spatial scale. This contribution, introduces a middleware program for the synchronization of icon-based software with GIS software. Parallel programming is used to boost simulation performance. In contrast to mainstream modeling environments such as SIMILE or NOVA, spatiotemporal modeling capabilities are supported by GIS interoperability. This enables interactive spatial analyses, access to …
Participatory Modelling To Assess Climate Impacts On Water Resources In The Big Wood Basin, Idaho, J. Koch, A. Inouye, D. Lach, J. Stevenson, J. P. Bolte
Participatory Modelling To Assess Climate Impacts On Water Resources In The Big Wood Basin, Idaho, J. Koch, A. Inouye, D. Lach, J. Stevenson, J. P. Bolte
International Congress on Environmental Modelling and Software
Many of the natural resource issues we face today cannot be fully understood using normal scientific methods or theories. When uncertainties or decision stakes are high, participation by an “extended peer community” can be critical to studying and managing complex systems since local expertise on land use and ecosystem processes may not otherwise be captured. We conducted a case study of participatory modelling to support natural resource management under a changing climate. Over a two-year period, we convened a Knowledge to Action Network (KTAN) of scientists and stakeholders interested in exploring the impacts of climate change in Idaho’s Big Wood …
R Package Mvghd: Causal Inference Procedure For Geographic High-Dimensional, Stéphane Bourrelly, Pascal Auquier
R Package Mvghd: Causal Inference Procedure For Geographic High-Dimensional, Stéphane Bourrelly, Pascal Auquier
International Congress on Environmental Modelling and Software
Causal statistic inference is a key issue in machine learning. The goal is designing procedures that are able to select relevant subsets of explanatory variables, which might help scientists to better understand the underlying mechanisms behind the studied phenomena. We present a causal statistic inference procedure, especially designed for Geographic High-dimensional Datasets (GHD). The promise of discovering unknown informative factors are as great as the intrinsic learning challenges in these complex datasets, which are more and more common in the fields of environment, health, ecology, epidemiology, geography, agriculture, etc. Firstly, we point out the difference between the variable selection strategies …
The Challenges To Social Entrepreneurship In Brazilian Art/Handicraft Organizations: Today And In The Future, Claudia Green Phd, Adnan Dhiyan
The Challenges To Social Entrepreneurship In Brazilian Art/Handicraft Organizations: Today And In The Future, Claudia Green Phd, Adnan Dhiyan
Wilson Center for Social Entrepreneurship
This is a case study of O Sol, a Brazilian art/handicraft social entrepreneurship cooperative that began over 50 years ago. O Sol produces authentic art/handcraft that is sold to tourists in Rio de Janeiro. The organization promotes human development and authentic Brazilian culture through the production and selling of art/handicrafts. However, today it is at risk economically, socially and culturally. To examine this case, students learn about social entrepreneurship, creating shared value and creating social value in tourism organizations as they examine the challenges of the globalization of authentic art tourism.

Scientific Eventuality Or Science Fiction: The Future Of People With Different Abilities, Deedee M. Bennett
Public Administration Faculty Publications
Consider this, we are living in a future [in-part] imagined over 30 years ago- in science fiction film and books. We may envision that 30 years from now we could live in a future with technology developed from the concepts we see in science fiction today. In this paper, the concepts of disability are challenged in the future based on the technologies imagined in the science fiction genre of the present and past. Focused on the sub-genre, Cyberpunk, current mainstream, as well as new emerging technologies inspired by science fiction are reviewed. Future disability is reimagined dependent on continued support …
A Model-Free Localization Method For Sensor Networks With Sparse Anchors, Maggie Xiaoyan Cheng, Wei Biao Wu
A Model-Free Localization Method For Sensor Networks With Sparse Anchors, Maggie Xiaoyan Cheng, Wei Biao Wu
Computer Science Faculty Research & Creative Works
This paper considers the problem of sensor node localization, where a total of an anchor nodes is used to determine the locations of other nodes based on the received signal strengths. Challenges arise when anchor nodes are sparse and locations of them are not at grid positions. A range-based machine learning algorithm is developed to tackle the challenges. Instead of using samples to calibrate the parameters of a chosen signal model, we use machine learning to estimate the signal propagation function and its parameters at the same time. It overcomes the model dependency issue of existing range-based algorithms and avoids …
Standardization Of Human-Computer-Interface For Geo-Fencing In Small Unmanned Aircraft Systems, David Thirtyacre, Robert Brents, Michael Goldfein, David Hunter, B. Terwilliger
Standardization Of Human-Computer-Interface For Geo-Fencing In Small Unmanned Aircraft Systems, David Thirtyacre, Robert Brents, Michael Goldfein, David Hunter, B. Terwilliger
Publications
The use of small unmanned aircraft systems (sUAS) has increased significantly in the past year. Geographic fencing (geo-fencing) is software built into most medium-cost consumer sUAS. This software is typically used to limit the altitude above launch point, the flight distance from the transmitting controller, and/or restrict flight inside a no-fly zone. While the concept of a geo-fence is simplistic, the human-computer-interface (HCI) varies drastically among platforms, and even between software iterations on the same platform. This research examines the HCI of three popular consumer-level sUAS with regard to geo-fencing. The software procedures and human interface for the DJI Inspire-1, …

A Multipurpose Soil Inorganic Carbon Prediction Model, Ben W. Kolosz, Peter Manning, Jorat M. Ehsan, Saran P. Sohi, David A.C. Manning
A Multipurpose Soil Inorganic Carbon Prediction Model, Ben W. Kolosz, Peter Manning, Jorat M. Ehsan, Saran P. Sohi, David A.C. Manning
International Congress on Environmental Modelling and Software
There is a lack of models to predict soil inorganic carbon (SIC) which are not only multipurpose, but can predict SIC in a variety of soils and materials. The importance of estimating SIC stocks is due to the large contribution they make towards total carbon in some soils. This paper proposes such a model which aims to account for the variance and geographical range of soils. As an example, one such use is the accurate prediction of passive SIC sequestration rates as this is currently a complex challenge, mainly due to environmental effects such as water, temperature and atmospheric CO …

In many parts of the U.S., population growth combined with continued demand for low-density housing is transforming the structure of peri-urban landscapes. Despite the substantial amount of privately owned land, the important decision-making roles that individual landowners play in shaping patterns of urbanization and landscape change is understudied. We introduce a data-informed simulation model developed to analyse the decision-making processes that determine spatial characteristics of fragmentation in peri-urban areas by combining the utility of a cellular automata urban growth algorithm (CA module), based on the FUTURES model, with an agent-based model (ABM module). The CA module is conceptualized as a …

Integrated Assessment Of Novel Two-Season Production Systems In Mato Grosso, Brazil, Marcelo Moraes, Affonso Libera, Evgeny Latynskiy, Anna Hampf, José Maria Silveira, Thomas Berger
International Congress on Environmental Modelling and Software
One of the most significant advantages of growing crops in Mato Grosso (in mid-western Brazil) is that farmers can grow two crops (in some specific cases even three) in the same season. From an economic point of view, on the one hand, this provides a strong comparative advantage. On the other hand, this increases the number of decision variables that a decision making agent has to take into account. The agricultural production planning is complex and dynamic and it needs to consider crop rotation/succession in accordance with annual variability of climatic conditions. We developed a region-specific bio-economic micro-simulation model in …

The Pasture Simulation Model – Evaluation Of Plant Acclimatory Effects On Grassland Systems In France, Serge Zaka, Renáta Sándor, Raphaël Martin, Gaëtan Louarn, Katja Klumpp, David Borras, Gianni Bellocchi
International Congress on Environmental Modelling and Software
The temperature responses of plant photosynthesis and respiration observed on single-plant species can be assumed to occur at the scale of a grassland ecosystem (which is a dynamic and competitive associations of plants). Based on the model for a single, fully expanded leaf as derived from experimental evidence and to gain insights into acclimatory and modulatory effects of growth temperature, we have: 1) improved a complex soil-vegetation-management model of grasslands, PaSim (Pasture Simulation model), and 2) evaluated it on multi-year datasets of plant biomass and C-water- energy fluxes in managed grassland systems. Illustrative results are presented for the French grassland …
Claiming The Politics Of Articulation Through Agency And Wholeness In Two Afro-Hispanic Postcolonial Narratives, Silvia Castro Borrego
Claiming The Politics Of Articulation Through Agency And Wholeness In Two Afro-Hispanic Postcolonial Narratives, Silvia Castro Borrego
Journal of International Women's Studies
Following a context-based approach and the tenets of post-positivist realist theory, this paper will analyze two post-colonial Afro-Hispanic novels immersed in their articulation of moving towards Caribbeanness within the phenomenon of Diaspora Literacy: María Nsue Angüe’s Ekomo (1983) and Michelline Dusseck’s Caribbean Echoes (1997). As part of the Diaspora Literacy, these texts will be read employing the search for wholeness as a theoretical tool, towards an epistemology of anti-colonial feminist struggle. These texts take active part in a decolonizing process that fosters a definition and vision of agency which makes wholeness possible, becoming an active expression of black women’s spirituality …

Carving Caribbean Spaces In Between: The Life Of Ruth Gourzong In 20th Century Puerto Limon, Costa Rica, Natasha Gordon-Chipembere
Journal of International Women's Studies
This paper attempts to make visible the community and their descendants of free Jamaican blacks who immigrated into the Atlantic Coast of Costa Rica (specifically Puerto Limon) at the turn of the twentieth century to help build the American owned Northern Railway and work on the banana plantations owned by the American owned United Fruit Company. I illustrate the life of my great grandmother, Ruth Gourzong as an example of a woman from this community who managed to thrive against the odds of racism and sexism during her life time in Costa Rica. In order to fully appreciate the context …

"Everything Remains The Same And Yet Nothing Is The Same": Neocolonialism In The Caribbean Diaspora Through The Language Of Family And Servitude, Laura Barrio-Vilar
Journal of International Women's Studies
This essay examines Jamaica Kincaid’s Lucy, a novel that tackles the process of decolonization from old and new forms of colonialism through the language of servitude and family (specifically, mother-daughter relationships). The novel’s protagonist is not only an example of the wave of West Indian migration and the feminization of labor, but her agency also provides Kincaid with the necessary platform to deploy her views on U.S. imperialism. I propose reading Lucy’s evolution toward self-determination as not only an individual but also a collective experience. I interpret the novel as an allegory that can help us better understand the …
Wifredo Lam, The Shango Priestess, And The Femme Cheval, Paula Sato
Wifredo Lam, The Shango Priestess, And The Femme Cheval, Paula Sato
Journal of International Women's Studies
This article examines Afro-Cuban painter Wifredo Lam and his iconic construction of Afro-Cuban identity. From the vantage point of a literary scholar rather than art historian, and in keeping with Lam’s description of his paintings as “poetry,” I read his artwork as terse lines of verse, rich in metaphors. Although Lam is regarded as the painter of Negritude, commonly understood as a male-centered movement, he distinguishes himself from his contemporaries by incorporating in his brand of Negritude two female figures as metaphors of the power to decolonize the mind. One of those figures is his Afro-Cuban godmother, Mantonica Wilson. Healer, …

A Narrative Review Of Maternal Depression Research Focusing On Women Of Caribbean Descent In The Diaspora And Caribbean Women In The Region, Fatimah Jackson-Best
Journal of International Women's Studies
Maternal depression is a global public health issue (Almond, 2009); however, much of the existing research on conditions like the ‘baby blues’ and postpartum depression have been conducted with White women in North America and Europe. This narrative review seeks to expand the scope of maternal depression research by including and analyzing maternal depression studies conducted with Caribbean descent women living in the Diaspora and women in the English-speaking Caribbean alongside some of the work from North America and Europe. Through this engagement with the existing research three thematic areas emerged. These are: widely used prevalence and incidence rates of …
Social Erotics: The Fluidity Of Love, Desire And Friendship For Same-Sex Loving Women In Trinidad, Krystal Ghisyawan
Social Erotics: The Fluidity Of Love, Desire And Friendship For Same-Sex Loving Women In Trinidad, Krystal Ghisyawan
Journal of International Women's Studies
Love takes many forms and can serve different functions in a person’s life. Some forms, such as romantic love, familial love, and love within friendship, while sometimes distinct, at other times cannot be separated. This paper discusses love and friendship for same-sex loving women in Trinidad, exploring this mutability of love, the functions of love and intimacy in these women’s lives, the role of social media and social circles for finding love, all while considering the notion that love amongst same-sex loving women is an act of resistance. Forty same-sex loving women were individually interviewed, and this paper is written …

Understanding the earth as a system requires integrating many forms of data from multiple fields. Builders and funders of the cyberinfrastructure designed to enable open data sharing in the geosciences risk a key failure mode: What if geoscientists do not use the cyberinfrastructure to share, discover and reuse data? In this study, we report a baseline assessment of engagement with the NSF EarthCube initiative, an open cyberinfrastructure effort for the geosciences. We find scientists perceive the need for cross-disciplinary engagement and engage where there is organizational or institutional support. However, we also find a possibly imbalanced involvement between cyber and …

Three-Dimensional Geological Model Of Quaternary Sediments In Walworth County, Wisconsin, Usa, Jodi Lau, Jason F. Thomason, David H. Malone, Eric W. Peterson
Faculty Publications - Geography, Geology, and the Environment
A three-dimensional (3D) geologic model was developed for Quaternary deposits in southern Walworth County, WI using Petrel, a software package primarily designed for use in the energy industry. The purpose of this research was to better delineate and characterize the shallow glacial deposits, which include multiple shallow sand and gravel aquifers. The 3D model of Walworth County was constructed using datasets such as the U.S. Geological Survey 30 m digital elevation model (DEM) of land surface, published maps of the regional surficial geology and bedrock topography, and a database of water-well records. Using 3D visualization and interpretation tools, more than …
Location Inference Of Social Media Posts At Hyper-Local Scale, Brian D. Mcclanahan
Location Inference Of Social Media Posts At Hyper-Local Scale, Brian D. Mcclanahan
Master's Theses
This paper describes an approach to infer the location of a social media post at a hyper-local scale based on its content, conditional to the knowledge that the post originates from a larger area such as a city or even a state. The approach comprises three components: (i) a discriminative classifier, namely, Logistic Regression (LR) which selects from a set of most probable sub-regions from where 1 a post might have originated; (ii) a clustering technique, namely, k-means, that adaptively partitions the larger geographic region into sub-regions based on the density of the posts; and (iii) a range of techniques …

Atlanta Ariejansseni, A New Species Of Shelled Heteropod From The Southern Subtropical Convergence Zone (Gastropoda, Pterotracheoidea), D Wall-Palmer, Ak Burridge, Ktca Peijnenburg
School of Geography, Earth and Environmental Sciences
The Atlantidae (shelled heteropods) is a family of microscopic aragonite shelled holoplanktonic gastropods with a wide biogeographical distribution in tropical, sub-tropical and temperate waters. The aragonite shell and surface ocean habitat of the atlantids makes them particularly susceptible to ocean acidification and ocean warming, and atlantids are likely to be useful indicators of these changes. However, we still lack fundamental information on their taxonomy and biogeography, which is essential for monitoring the effects of a changing ocean. Integrated morphological and molecular approaches to taxonomy have been employed to improve the assessment of species boundaries, which give a more accurate picture …
