    Commercialization of the Nature-Resource Potential of Anthropogenic Objects (on the Example of Exhausted Mines and Quarries).D. E. Reshetniak S. E. Sardak, O. P. Krupskyi, S. I. Korotun & Sergii Sardak - 2019 - Journal of Geology, Geography and Geoecology 28 (1):180-187.
    Abstract. In this article we developed scientific and applied foundations of commercialization of the nature-resource potential of anthropogenic objects, on the example of exhausted mines. It is determined that the category of “anthropogenic object” can be considered in a narrow-applied sense, as specific anthropogenic objects to ensure the target needs, and in a broad theoretical sense, meaning everything that is created and changed by human influence, that is the objects of both artificial and natural origin. It was determined that problems (...)

    What Types of Values Enter Simulation Validation and What Are Their Roles?Gertrude Hirsch Hadorn & Christoph Baumberger - 2019 - In Claus Beisbart & Nicole J. Saam (eds.), Computer Simulation Validation: Fundamental Concepts, Methodological Frameworks, and Philosophical Perspectives. Cham, Switzerland: pp. 961-979.
    Based on a framework that distinguishes several types, roles and functions of values in science, we discuss legitimate applications of values in the validation of computer simulations. We argue that, first, epistemic values, such as empirical accuracy and coherence with background knowledge, have the role to assess the credibility of simulation results, whereas, second, cognitive values, such as comprehensiveness of a conceptual model or easy handling of a numerical model, have the role to assess the usefulness of a model for (...)

    Uncertainty Quantification Using Multiple Models - Prospects and Challenges.Reto Knutti, Christoph Baumberger & Gertrude Hirsch Hadorn - 2019 - In Claus Beisbart & Nicole J. Saam (eds.), Computer Simulation Validation: Fundamental Concepts, Methodological Frameworks, and Philosophical Perspectives. Cham, Switzerland: pp. 835-855.
    Model evaluation for long term climate predictions must be done on quantities other than the actual prediction, and a comprehensive uncertainty quantification is impossible. An ad hoc alternative is provided by coordinated model intercomparisons which typically use a “one model one vote” approach. The problem with such an approach is that it treats all models as independent and equally plausible. Reweighting all models of the ensemble for performance and dependence seems like an obvious way to improve on model democracy, yet (...)

    Farmers' Markets in Prague: A New Challenge Within the Urban Shoppingscape.Jana Spilková, Lenka Fendrychová & Marie Syrovátková - 2013 - Agriculture and Human Values 30 (2):179-191.
    Farmers’ markets are a relatively recent phenomenon in Prague, Czechia. The first of them was opened in the autumn of 2009, but the real boom started in the spring/summer of 2010. The survey introduced in this paper is concerned with the study of alternative food networks and farmers’ markets. It offers the results of methodological triangulation based on: (1) the data obtained via the questionnaire survey, (2) market organizers’ reflections on the customer structure, motivation for shopping at farmers’ markets and (...)

    Applying Big Data Beyond Small Problems in Climate Research.Benedikt Knüsel, Marius Zumwald, Christoph Baumberger, Gertrude Hirsch Hadorn, Erich M. Fischer, Reto Knutti & David M. Bresch - 2019 - Nature Climate Change 9 (March 2019):196-202.
    Commercial success of big data has led to speculation that big-data-like reasoning could partly replace theory-based approaches in science. Big data typically has been applied to ‘small problems’, which are well-structured cases characterized by repeated evaluation of predictions. Here, we show that in climate research, intermediate categories exist between classical domain science and big data, and that big-data elements have also been applied without the possibility of repeated evaluation. Big-data elements can be useful for climate research beyond small problems if (...)

    The Orbital Space Environment and Space Situational Awareness Domain Ontology – Towards an International Information System for Space Data.Robert J. Rovetto - 2016 Sept - In Proceedings of The Advanced Maui Optical and Space Surveillance Technologies (AMOS) Conference.
    The orbital space environment is home to natural and artificial satellites, debris, and space weather phenomena. As the population of orbital objects grows so do the potential hazards to astronauts, space infrastructure and spaceflight capability. Orbital debris, in particular, is a universal concern. This and other hazards can be minimized by improving global space situational awareness (SSA). By sharing more data and increasing observational coverage of the space environment we stand to achieve that goal, thereby making spaceflight safer and expanding (...)

I offer an unwavering positive answer to this question, and state the reasons for it while considering the broad challenges and benefits of (human) spaceflight. Space exploration is a human activity that is intrinsically forward-looking, and as such, has positive potential. Both national and international space programs can galvanize the population, inspire the youth, foster job-creation, and motivate the existing workforce. (...)

    This paper deals with one of the first attempts to measure simple reactions in humans. The Swiss astronomer Adolph Hirsch investigated personal differences in the speed of sensory transmission in order to achieve accuracy in astronomy. His controversial results, however, started an intense debate among both physiologists and astronomers who disagreed on the nature of these differences. Were they due to different eyes or brains, or to differences in skill and education? Furthermore, they debated how to eliminate them. Some, for (...)

    The orbital debris problem presents an opportunity for inter-agency and international cooperation toward the mutually beneficial goals of debris prevention, mitigation, remediation, and improved space situational awareness (SSA). Achieving these goals requires sharing orbital debris and other SSA data. Toward this, I present an ontological architecture for the orbital debris and broader SSA domain, taking steps in the creation of an orbital debris ontology (ODO).

Part of the reason for this is that geology is seen as a “derivative” science as compared to its “experimental” counterparts (for instance, physics and chemistry). However, with current global issues facing the populations of the world (climate change, scarcity of clean water, increasing fossil fuel usage), being geoscience literate is a must. We will (...)

    The Optimization of Irrigation Networks Using Genetic Algorithms.Francisco Fernando Noronha Marcuzzo - 2014 - JWARP 6:1124-1138.
    Mathematical-computational optimisation models of irrigation networks with a distributed flow that are capable of providing hydraulic data are important for understanding the behaviour of a system in relation to the distribution of the hydraulic head (energy) and the pressure in the pipes of the network. The objective of this study was to examine the distribution of the parameters of hydraulic irrigation pipes, which were optimised using genetic algorithms. The degree of the optimisation was evaluated with the help of the genetic (...)

    Degradation of Primate Habitat at Tesso Nilo Forest with Special Emphasis on Riau Pale-Thighed Surili (Presbytis Siamensis Cana).Jatna Supriatna - 2014 - Journal of Environmental Protection 5:1145-1152.
    The habitat of Riau pale-thighed surili (Presbytis siamensis cana) located in Riau province of Sumatra island between Siak in the north and Indragiri rivers in the south, has been seriously degraded in the last a few decades. This swampy peat land forest has been degraded by frequent burning during the dry season. These problems originated because of poor governance on the forest management, and the construction of two access roads by the owners of logging concessions and wood pulp plantations. This (...)

    Reflections on the Green Economy (Redemption of the Principles of Mill and Pigou): A View of a Brazilian Environmentalist.João Batista Drummond Câmara - 2014 - Journal of Environmental Protection 5:1153-1168.
    The current context of global efforts in the pursuit of sustainable development can be characterized by the perception of the scientific-technological losses of ecosystems and ecosystem services and their consequences for the survival of humanity in the face of threats of imbalances in the basic conditions for survival such as food production, the environmental quality, natural control of pests and diseases, loses of biodiversity and climate changes. Some recent initiatives at global, regional and local level are pointed and some conceptual (...)

    Changes in Human Population Characteristics and Environmental Change in the West Matogoro Catchment Area of Songea, Tanzania.Michael J. Haule - 2014 - Natural Resources 5:746-760.
    The study was carried out in West Matogoro Catchment Area (WMCA) of Songea, Tanzania, to establish whether for the period between intercensal periods 1978-1988 and 1988-2002, and between 2002 and 2005 characteristics of human population of the area had changed in terms of size, age structure and sex composition. In case it did, then the study had to establish whether such changes may be used to explain the observed forest cover change that occurred in the area. Establishing whether the observed (...)

    Denitrification in a Soil Under Wheat Crop in the Humid Pampas of Argentina.Liliana Inés Picone - 2014 - Open Journal of Soil Science 4:312-322.
    The need to accurately estimate gaseous nitrogen losses from soils is required to have a better understanding of the processes involved as well as soil and environmental conditions, and management practices contributing to these emissions. The objective was to quantify the denitrification rate using undisturbed cores with acetylene, as related to nitrogen (N) fertilization rate in a spring wheat crop (Triticum aestivum L.) under conventional tillage. Soil denitrification losses remained low throughout most of the growing season, when water-filled pore space (...)

    Comparing Forests Across Climates and Biomes: Qualitative Assessments, Reference Forests, and Regional Inter-Comparisons.Carl Salk, Ulrich J. Frey & Hannes Rusch - 2014 - PLoS ONE 9 (4):e94800.
    Communities, policy actors and conservationists benefit from understanding what institutions and land management regimes promote ecosystem services like carbon sequestration and biodiversity conservation. However, the definition of success depends on local conditions. Forests’ potential carbon stock, biodiversity, and rate of recovery following disturbance are known to vary with a broad suite of factors including temperature, precipitation, seasonality, species’ traits and land use history. Methods like forest changes over time , and comparison with 'pristine' reference forests have been proposed to compare (...)

    True Grid.Barry Smith - 2001 - In D. Montello (ed.), Spatial Information Theory: Foundations of Geographic Information Science. New York: Springer. pp. 14-27.
    The Renaissance architect, moral philosopher, cryptographer, mathematician, Papal adviser, painter, city planner and land surveyor Leon Battista Alberti provided the theoretical foundations of modern perspective geometry. Alberti’s work on perspective exerted a powerful influence on painters of the stature of Albrecht Dürer, Leonardo da Vinci and Piero della Francesca. But his Della pittura of 1435–36 contains also a hitherto unrecognized ontology of pictorial projection. We sketch this ontology, and show how it can be generalized to apply to representative devices in (...)

    Arthur G. Tansley’s ‘New Psychology’ and its Relation to Ecology.Joachim L. Dagg - 2007 - Web Ecology 2007.
    In 1935, A. G. Tansley, who was knighted later, proposed the ecosystem concept. Nevertheless, this concept was not without predecessors. Why did Tansley’s ecosystem prevail and not one of its competitors? The purpose of this article is to pin the distinguishing features of Tansley’s ecosystem down, as far as the published record allows. It is an exercise in finding the difference that made a difference. Besides being a pioneering ecologist, Tansley was an adept of psychoanalysis. His interest even led him (...)

    Testing Times: Confirmation in the Historical Sciences.Ben Jeffares - 2008 - Dissertation, Australian National University
    In this thesis, I argue that a good historical science will have the following characteristics: Firstly, it will seek to construct causal histories of the past. Secondly, the construction of these causal histories will utilise well-tested regularities of science. Additionally, well-tested regularities will secure the link between observations of physical traces and the causal events of interest. However, the historical sciences cannot use these regularities in a straightforward manner. The regularities must accommodate the idiosyncrasies of the past, and the degradation (...)
