Unpacking occupational health data in the service sector: from bayesian network...
Pazo, María; Boente, Carlos; Albuquerque, M.T.D.; Gerassis, Saki; Roque, Natália; Taboada, JavierThe health status of the service sector workforce is a significant unknown in the field of medical geography. While spatial epidemiology has made progress in predicting the relationship between human health and the environment, there are still important challenges that remain unsolved. The main issue lies in the inability to statistically determine and visually represent all spatial concepts, as there is a need...
Unpacking occupational health data in the tertiary sector. From spatial cluster...
Pazo, María; Boente, Carlos; Albuquerque, M.T.D.; Roque, Natália; Gerassis, Saki; Taboada, JavierThe health status of the service sector workforce is a great unknown for medical geography. Despite the advances carried out by spatial epidemiology to predict spatial patterns of disease incidence, there are important challenges unsolved. In particular, the main issue resides in the ability to effectively simplify and visually represent the problem domain, given the need to cover very different service activit...
Future habitat suitability for species under climate change: lessons learned fr...
Gerassis, Saki; Albuquerque, M.T.D; Roque, Natália; Ribeiro, Sílvia; Taboada, Javier; Ribeiro, M.M.A.Climate change is already a reality, and habitat loss is affecting relentlessly tree species distributions. The strawberry tree (Arbutus unedo L., Ericaceae) is a Mediterranean evergreen tree used in this article as a case study to evince its expected threatening situation in the upcoming age. This research work seeks to identify the bioclimatic and physiographic variables that have the most impact on the straw...
Mapping occupational health risk factors in the primary sector: a novel supervi...
Gerassis, Saki; Boente, Carlos; Albuquerque, M.T.D.; Ribeiro, M.M.A.; Abad, A.; Taboada, JavierWorkers around the world spend nearly a quarter of their time at work Occupational health is gaining great importance due to the profound impact on people long term health. The health status of the primary sector workforce is a great unknown for medical geography where health maps and spatial patterns have not been able to explain years of changing disease rates. This article proposes a new approach based on a ...
Understanding complex blasting operations: a structural equation model combinin...
Gerassis, Saki; Albuquerque, M.T.D.; García, J.F.; Boente, Carlos; Giráldez, E.; Taboada, Javier; Martín, JoséA probabilistic Structural Equation Model (SEM) based on a Bayesian network construction is introduced to perform effective safety assessments for technicians and managers working on-site. Using novel AI software, the introduced methodology aims to show how to deal with complex scenarios in blasting operations, where typologically different variables are involved. Sequential Bayesian networks, learned from the ...
Local versus regional soil screening levels to identify potentially polluted areas
Boente, Carlos; Gerassis, Saki; Albuquerque, M.T.D.; Taboada, Javier; Gallego, J.R.Soil screening levels (SSLs) are reference threshold values required by environmental laws, established based on soil geochemical background data from often-extensive sampling areas. Such areas are often inappropriate for interpreting the true risk of pollution in small areas, since they overlook local factors (e.g., geology, industry, and traffic), which are unfeasible to encompass in large-scale samplings. To...
Developing a new bayesian risk index for risk evaluation of soil contamination
Albuquerque, M.T.D.; Gerassis, Saki; Sierra, C.; Taboada, Javier; Martín, José; Antunes, I.M.H.R.; Gallego, J.R.Industrial and agricultural activities heavily constrain soil quality. Potentially Toxic Elements (PTEs) are a threat to public health and the environment alike. In this regard, the identification of areas that require remediation is crucial. In the herein research a geochemical dataset (230 samples) comprising 14 elements (Cu, Pb, Zn, Ag, Ni, Mn, Fe, As, Cd, V, Cr, Ti, Al and S) was gathered throughout eight d...
Modelação ecológica em medronheiro usando redes Baiesianas
Albuquerque, M.T.D.; Gerassis, Saki; Roque, Natália; Ribeiro, Sílvia; Taboada, Javier; Martín, José; Ribeiro, M.M.A.O medronheiro (Arbutus unedo L.) tem potencial para ser uma cultura de sucesso comercial em várias regiões de Portugal, onde está bem-adaptado ao clima e solos. A espécie tem sido usada pelas populações locais para consumo do fruto em fresco ou processado, sobretudo como aguardente, no entanto continua a ser uma espécie largamente negligenciada, ainda que tenha muitos usos comerciais possíveis, desde a produção...
Aquifer vulnerability mapping and associated spatial uncertainty
Alonso, Leticia; Albuquerque, M. T. D.; Martínez-Alegría, Toberto; Antunes, I. M. H. R.; Taboada, JavierQuantitative estimation of water resources is indispensable when it comes to getting the sustainability of aquifers through planning. This becomes an essential aspect in areas whose primary economic activity is agriculture, in which ensure the availability of water means ensuring the sustainability of the societal and economic systems. This is the example of the Cuellar Moor karstic aquifer, located in the inte...
Distribución de nitratos e incertidumbre espacial asociada: caso de estudio del...
Alonso, Leticia; Albuquerque, M. Teresa; Martínez-Alegría, Roberto; Antunes, Isabel Margarida Horta Ribeiro; Taboada, JavierLa gestión de los recursos hídricos es una prioridad para el desarrollo de los lugares y el bienestar de las personas, sobre todo en las masas de agua más afectadas por pressiones antrópicas. Por otra parte, la creciente aparición de fenómenos repentinos y extremos insta a la planificación del recurso en situaciones especificas. En este estúdio, se ha simulado la evolución de la dispersión de nitratos como la b...
