A Sense of Place: Human Geography in the Early Childhood Classroom
Social Studies: From a Sense of Self to a Sense of the World Pamela Brillante and Sue Mankiw Preschool Through Primary Grades A Sense of Place: Human Geography in the Early Childhood Classroom Walking downtown is four-year-old Abby’s favorite thing to do with her dad. Today is the first day that Abby hasn’t had to wear a coat on their walk. They walk under shady trees and stop to notice all the white flowers blooming outside the library where Abbey and her grandma go for story hour with Abby’s friends. The smell of lilies of the valley permeates the air. As they get closer to downtown, Dad picks Abby up while they cross the broken sidewalk near the post office so she does not get hurt on the rough terrain. It can be difficult for her to navigate uneven ground with her walker. Approaching the town’s music stage, Abby tugs on her dad’s sleeve; she wants to hear the musicians playing their shiny instruments. Abby points out the sign that says STOP on the busy street corner by Poppy’s Bakery. The nice women who work there always talk to Abby and let her pick out a cookie while her dad buys warm, delicious-smelling bread for Sunday dinner. Abby loves going to “her downtown,” where she knows she is part of the community of friends, neighbors, and merchants she meets along the way. 1, 2, 3 ® © iStock.com/ktaylorg 2 Young Children July 2015 lthough they may not realize it, Abby physical world around them and in the social and cultural and her dad are studying geography on their world they share with others. -

State Standard for Hydrologic Modeling Guidelines
ARIZONA DEPARTMENT OF WATER RESOURCES FLOOD MITIGATION SECTION State Standard For Hydrologic Modeling Guidelines Under the authority outlined in ARS 48-3605(A) the Director of the Arizona Department of Water Resources establishes the following standard for Hydrologic Modeling Guidelines in Arizona. State Standard for Hydrologic Modeling, or “guidelines for the experienced modeler”, has been developed to address hydrologic conditions for a variety of statewide watersheds. Included are problems and situations identified by the State Standard Work Group (SSWG) and floodplain managers. The intended audience is statewide; engineers, professionals and Floodplain Administrators. The following topics are included: • Hydrologic Model comparison and recommendation • Guidelines and parameters • Model application for specific situations, and associated hydrologic parameters • Precipitation values (NOAA 14) • Storm duration • Unique conditions, such as wildfire burn, overgrazing, logging, drought, rapid snowmelt, urbanization. The State Standard includes examples addressing the above key issues. This requirement is effective August, 2007. Copies of this State Standard and the State Standard Technical Supplement can be obtained by contacting the Department’s Water Engineering Section at (602) 771-8652.

In the Beginning Was Economic Geography’ – a Science Studies Approach to Disciplinary History1 Trevor J
Progress in Human Geography 25,4 (2001) pp. 521–544 ‘In the beginning was economic geography’ – a science studies approach to disciplinary history1 Trevor J. Barnes Department of Geography, 1984 West Mall, University of British Columbia, Vancouver BC V6T 1Z2, Canada Abstract: Science studies are an increasingly prominent interdisciplinary body of work. Now a diverse literature, one of its most consistent and common themes is a reluctance to accept the standard model of scientific explanation (‘internalism’) that conceives scientific knowledge, and the disciplines with which it is associated, as the product of a rationality that is progressively realized over time. Instead, science studies emphasize the importance of local circumstances in shaping knowledge, which, in turn, makes such knowledge messy and context-dependent. The purposes of this paper are twofold. The first is to provide a selective review of science studies. In particular, the paper recognizes three subtraditions within the larger genre: Mertonian insti- tutionalism, the sociology of scientific knowledge, and cultural studies of science. The second purpose is to begin developing a case study in order to apply such literature, that of the institu- tional origins of economic geography during the late nineteenth and early twentieth centuries, and linked to a series of wider social processes around commercial trade and imperialism. To make the case study manageable, I concentrate on only two authors and their respective key books: the Scottish geographer George Chisholm, who wrote the first English-language economic geography textbook, A handbook of commercial geography (1889); and the American geographer J. Russell Smith, author of the first US college text in economic geography, Industrial and commercial geography (1913). -
Natural Drainage Basins As Fundamental Units for Mine Closure Planning: Aurora and Pastor I Quarries
Natural Drainage Basins as Fundamental Units for Mine Closure Planning: Aurora and Pastor I Quarries Cristina Martín-Moreno1, María Tejedor1, José Martín1, José Nicolau2, Ernest Bladé3, Sara Nyssen1, Miguel Lalaguna2, Alejandro de Lis1, Ivón Cermeño-Martín1 and José Gómez4 1. Faculty of Geological Sciences, Universidad Complutense de Madrid, Spain 2. Polytechnic School, Universidad de Zaragoza, Spain 3. Institut FLUMEN, Universitat Politècnica de Catalunya, Spain 4. Fábrica de Alcanar, Cemex España ABSTRACT The vast majority of the Earth’s ice-free land surface has been shaped by fluvial and related slope geomorphic processes. Drainage basins are consequently the most common land surface organization units. Mining operations disrupt this efficient surface structure. Therefore, mine restoration lacking stable drainage basins and networks, “blended into and complementing the drainage pattern of the surrounding terrain” (in the sense of SMCRA 1977), will be always limited. The pre-mine drainage characteristics cannot be replicated, because mining creates irreversible changes in earth physical properties and volumes. However, functional drainage basins and networks, adapted to the new earth material properties, can and should be restored. Dominant current mine restoration practice, typically, either lacks a drainage network or has a deficient, non-natural, drainage design. Extensive literature provides evidence that this is a common reason for mined land reclamation failure. These conventional drainage engineered solutions are not reliable in the long term without guaranteed constant maintenance. Additionally, conventional landform design has low ecological and visual integration with the adjoining landscapes, and is becoming rejected by public and regulators, worldwide. For these reasons, fluvial geomorphic restoration, with a drainage basin approach, is receiving enormous attention. -
“History and Philosophy of Geography I: the Slow, the Turbulent, and the Dissenting”
“HISTORY AND PHILOSOPHY OF GEOGRAPHY I: THE SLOW, THE TURBULENT, AND THE DISSENTING” INNES M. KEIGHREN AUTHOR’S POST-PRINT VERSION ACCEPTED FOR PUBLICATION IN PROGRESS IN HUMAN GEOGRAPHY DOI: 10.1177/0309132516653285 History and philosophy of geography I: The slow, the turbulent, and the dissenting Innes M Keighren Royal Holloway, University of London, UK Abstract This report takes as its prompt John K Wright’s 1925 ‘plea for the history of geography’—an early call for an inclusive account of geographical thought and practice, embracing both professional and amateur ways of knowing. In reflecting on the extent to which contemporary histories of geography realise the scope of Wright’s ambition, the paper considers how external pressures, such as neoliberalism and academia’s audit culture, function to shape and constrain the writing of those histories. The paper argues for the value of ‘slow’ scholarship as an act of political resistance and as a sine qua non of nuanced and comprehensive historiography. The report concludes by examining how biographical and genealogical approaches to narrating geography’s histories have important implications for the decisions made about inclusion and exclusion, about what and who counts in geography. Keywords biography, genealogy, geosophy, histories of geography, John K Wright, neoliberal academia, slow scholarship The history of geography is often regarded as a somewhat antiquarian and useless background to modern geography … or as the harmless hobby of collectors of old maps. (Wright, 1925a: 194) The history of geography as a whole and in its wider bearings has been neglected … or at least it has not received the attention which any enthusiast may, perhaps, be permitted to regard as its due.
