A Cutting-Plane Method For Contiguity-Constrained Spatial Aggregation, Johannes Oehrlein, Jan-Henrik Haunert Dec 2017

A Cutting-Plane Method For Contiguity-Constrained Spatial Aggregation, Johannes Oehrlein, Jan-Henrik Haunert

Journal of Spatial Information Science

Aggregating areas into larger regions is a common problem in spatial planning, geographic information science, and cartography. The aim can be to group administrative areal units into electoral districts or sales territories, in which case the problem is known as districting. In other cases, area aggregation is seen as a generalization or visualization task, which aims to reveal spatial patterns in geographic data. Despite these different motivations, the heart of the problem is the same: given a planar partition, one wants to aggregate several elements of this partition to regions. These often must have or exceed a particular size, be …

Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus Dec 2017

Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus

Journal of Spatial Information Science

Research on provenance, which focuses on different ways to describe and record the history of changes and advances made throughout an analysis process, is an integral part of visual analytics. This paper focuses on providing the provenance of insight and rationale through visualizations while emphasizing, first, that this entails a profound understanding of human cognition and reasoning and that, second, the special nature of spatiotemporal data needs to be acknowledged in this process. A recently proposed human reasoning framework for spatiotemporal analysis, and four guidelines for the creation of visualizations that provide the provenance of insight and rationale published in …

Vgi In Surveying Engineering: Introducing Collaborative Cloud Land Surveying, Ioannis Sofos, Vassilios Vescoukis, Maria Tsakiri

Journal of Spatial Information Science

olunteered geographic information (VGI) has enabled many innovative applications in various scientific fields. This paper introduces a new framework called "collaborative cloud-based land surveying" (CCLS) that uses VGI principles for data sharing among surveyor engineers to boost the productivity and improve the quality of their applications. A cloud-based spatio-temporal data repository is presented, aiming to facilitate the sharing of VGI among surveyor engineers. A fully-functional distributed software application has been developed and used to apply CCLS in a large-scale land surveying project run by the Greek Ministry of Culture, which involves the mapping of the historic center of Athens. Results …

Sailing: Cognition, Action, Communication, Thora Tenbrink, Frank Dylla Dec 2017

Sailing: Cognition, Action, Communication, Thora Tenbrink, Frank Dylla

Journal of Spatial Information Science

How do humans perceive and think about space, and how can this be represented adequately? For everyday activities such as locating objects or places, route planning, and the like, many insights have been gained over the past few decades, feeding into theories of spatial cognition and frameworks for spatial information science. In this paper, we explore sailing as a more specialized domain that has not yet been considered in this way, but has a lot to offer precisely because of its peculiarities. Sailing involves ways of thinking about space that are not normally required (or even acquired) in everyday life. …

Quantifying Space, Understanding Minds: A Visual Summary Approach, Mark Simpson, Kai-Florian Richter, Jan Oliver Wallgrün, Alexander Klippel Dec 2017

Quantifying Space, Understanding Minds: A Visual Summary Approach, Mark Simpson, Kai-Florian Richter, Jan Oliver Wallgrün, Alexander Klippel

Journal of Spatial Information Science

This paper presents an illustrated, validated taxonomy of research that compares spatial measures to human behavior. Spatial measures quantify the spatial characteristics of environments, such as the centrality of intersections in a street network or the accessibility of a room in a building from all the other rooms. While spatial measures have been of interest to spatial sciences, they are also of importance in the behavioral sciences for use in modeling human behavior. A high correlation between values for spatial measures and specific behaviors can provide insights into an environment's legibility, and contribute to a deeper understanding of human spatial …

Modeling And Manipulating Spacetime Objects In A True 4d Model, Ken Arroyo Ohori, Hugo Ledoux, Jantien Stoter Dec 2017

Modeling And Manipulating Spacetime Objects In A True 4d Model, Ken Arroyo Ohori, Hugo Ledoux, Jantien Stoter

Journal of Spatial Information Science

The concept of spacetime has long been used in physics to refer to models that integrate 3D space and time as a single 4D continuum. We argue in this paper that it is also advantageous to use this concept in a practical geographic context by realizing a true 4D model, where time is modeled and implemented as a dimension in the same manner as the three spatial dimensions. Within this paper we focus on 4D vector objects, which can be implemented using dimension-independent data structures such as generalized maps. A 4D vector model allows us to create and manipulate models …

Cognitively Plausible Representations For The Alignment Of Sketch And Geo-Referenced Maps, Sahib Jan, Angela Schwering, Carl Schultz, Malumbo Chaka Chipofya Dec 2017

Cognitively Plausible Representations For The Alignment Of Sketch And Geo-Referenced Maps, Sahib Jan, Angela Schwering, Carl Schultz, Malumbo Chaka Chipofya

Journal of Spatial Information Science

In many geo-spatial applications, freehand sketch maps are considered as an intuitive way to collect user-generated spatial information. The task of automatically mapping information from such hand-drawn sketch maps to geo-referenced maps is known as the alignment task. Researchers have proposed various qualitative representations to capture distorted and generalized spatial information in sketch maps, however thus far the effectiveness of these representations has not been evaluated in the context of an alignment task. This paper empirically evaluates a set of cognitively plausible representations for alignment using real sketch maps collected from two different study areas with the corresponding geo-referenced maps. …

Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube Dec 2017

Topological Augmentation: A Step Forward For Qualitative Partition Reasoning, Matthew P. Dube

Journal of Spatial Information Science

The current state of the art for partition based qualitative spatial reasoning systems such as the 9-intersection, 9+-intersection, direction relation matrix, and peripheral direction relations is that of the binary set intersection — either empty or non-empty — conveying the intersection (or lack thereof) of an object in the sets deriving the partition. While such representations are sufficient for topological components of objects, these representations are not sufficient for various tasks in qualitative spatial reasoning (composition, representation transfer, converse, etc.) regarding partitions as tiles. Topological augmentation expands the current binary status quo into a system of assigning topological relations between …

Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker Dec 2017

Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker

Human–Wildlife Interactions

We built on the existing capacity of a nongovernmental organization called the Blackfoot Challenge to proactively address wolf (Canis lupus)-livestock conflicts in the Blackfoot Valley of Montana. Beginning in 2007, wolves started rapidly recolonizing the valley, raising concerns among livestock producers. We built on an existing program to mitigate conflicts associated with an expanding grizzly bear population and worked within the community to build a similar program to reduce wolf conflicts using an integrative, multi-method approach. Efforts to engage the community included one-on-one meetings, workshops, field tours, and regular group meetings as well as opportunities to participate in …

Small Schools And The Issue Of Scale, Patricia A. Wasley, Michelle Fine Dec 2017

Small Schools And The Issue Of Scale, Patricia A. Wasley, Michelle Fine

Occasional Paper Series

Wasley and Fine write this essay to respond to the oft-heard claim that small schools are not a systemic reform strategy. They argue, instead, that there is now a broad professional and community consensus for small schools; major policy moves within urban, suburban, and rural communities are being advanced to create and maintain small schools, and substantial social science evidence documents the efficiency and equity potential of small schools .

Persuasive Kinship: Human–Plant Relations In Southwest Amazonia, Fabiana Maizza Dec 2017

Persuasive Kinship: Human–Plant Relations In Southwest Amazonia, Fabiana Maizza

Tipití: Journal of the Society for the Anthropology of Lowland South America

Based on my ethnographic research with the Jarawara people, an indigenous society in the Southwest Amazonia, the article explores the idea of thinking kinship as persuasion. Among the Jarawara, children can have more than one father, which is well known in Americanist literature, but there would exist as well an original practice what we could call "multi-maternity". I also observe that the Jarawara can have diverse parental relations - some of their children are human, while others are plants. This occurs in a system of raising (nayana) in which children and plants are raised by a father and/or a mother …

Canela Shamanism: Shamans’ Accounts, “Journeying,” And Delimitation Of Shamanic Terms, William H. Crocker Dec 2017

Canela Shamanism: Shamans’ Accounts, “Journeying,” And Delimitation Of Shamanic Terms, William H. Crocker

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this article I recount the stories of various shamans I have worked with throughout many decades of fieldwork among the Ramkokamekra-Canela (Eastern Timbira) of central Maranhão state, Brazil. Along with their narratives, I provide ethnographic context in order to address the following questions: (1) Who is a shaman? (2) What is shamanism? Is shamanism better understood (3) as a process or a method that is carried out to achieve certain ends, or is it better understood (4) as a particular set of beliefs associated with particular cultures? Additionally, (5) are altered or shamanic states of consciousness found in Canela …

Devolution Of Power And Woreda Or District Development In Benshangul Gumuz Regional State: The Case Of Metkel Zone (North West Ethiopia), Aldo Morka Atnafu Dec 2017

Devolution Of Power And Woreda Or District Development In Benshangul Gumuz Regional State: The Case Of Metkel Zone (North West Ethiopia), Aldo Morka Atnafu

International Journal of African Development

Decentralized governance offers opportunities for achieving development through good governance and community participation at the grass root level (Ayenew, 2007). Ethiopia has adopted two phases of decentralization, namely decentralizing of power from the federal government to the regional level and from the regional to the woreda level (Gebre-Egziabher & Berhanu, 2007). Thus, this study has aimed at assessing the effect of the woreda level decentralization on the development of the Metekel zone. In particular, it examines the nature of political, administrative and fiscal decentralization in woredas. The study was conducted in two selected woreda, Bulen and Mandura. Data were collected …

Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba Dec 2017

Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba

International Journal of Speleology

Endemic and rare species as bioindicators of habitat vulnerability were used to develop protection and management plans for biotope prioritization (mainly islands habitats, lava tubes or groundwaters). Due to their narrow distribution, the endemic species (species confined to a restricted geographic area) are more susceptible to ecological disequilibrium and habitat loss than the widespread ones. Consequently, endemics become endangered in the context of ecological disturbance caused by anthropogenic pressure, making them suitable candidates to assess environmental preservation needs. Taking into consideration that most of the stygobitic and troglobitic species are endemic and confined to specific karst areas, based on their …

Globalization Tumult And Civilizational Greatness, Pradip N. Khandwalla Dec 2017

Globalization Tumult And Civilizational Greatness, Pradip N. Khandwalla

Markets, Globalization & Development Review

In the kind of tumultuous, strife-torn, and stressful world we are living in, we need to ask the questions: “Is our civilization moving in the right direction? What makes a civilization great?” Greed for power and greed for money, unless offset by a shared conception of civilizational excellence, often degenerate into widespread corruption, fraud, and violence. In developing countries like India, the challenge is to design a civilization that uses the creativity and enterprise of the market economy, the freedom of choice of democracy, and the altruism of the developmental state – to reverse degeneration and foster social, economic, and …

Collective Narcissism, Anti-Globalism, Brexit, Trump, And The Chinese Juggernaut, Russell Belk Dec 2017

Collective Narcissism, Anti-Globalism, Brexit, Trump, And The Chinese Juggernaut, Russell Belk

Markets, Globalization & Development Review

Brexit and the election of Trump both relied on a particular type of nationalistic appeal to collective narcissism — an exaggerated emotional belief that the nation’s greatness is being undermined by other nations and other people. This tendency is catered to by appeals to make the nation great again by shutting borders and embracing isolationism while scapegoating refugees and immigrants. The rise of jingoistic leaders like Trump, Putin, and Erdogan can be explained by such appeals. But China, which has long suffered feelings of national humiliation is reacting in quite different ways that embrace globalism, even while rejecting multiculturalism. This …

A Spatial Collaboration: Building A Multi-Institution Geospatial Data Discovery Portal, Mara Blake, Karen Majewicz, Ryan Mattke, Kathleen W. Weessies Nov 2017

A Spatial Collaboration: Building A Multi-Institution Geospatial Data Discovery Portal, Mara Blake, Karen Majewicz, Ryan Mattke, Kathleen W. Weessies

Collaborative Librarianship

As academic education and research increasingly take advantage of geospatial data and methodologies, we see a corresponding exponential growth in the number of available geospatial resources in the form of GIS datasets and scanned historical maps. However, users can experience difficulty finding these resources due to the unconnected multitude of platforms and clearinghouses that host them. Additionally, the resources are not always well described with web semantic metadata that facilitates discovery. In response to this challenge, The Big Ten Academic Alliance Geospatial Data Project began in 2015 to provide discoverability, facilitate access, and connect scholars to geospatial resources. Our project …

You Are What You Eat: Gastronomy & Geography Of Southern Spain, Katherine F. Perry Oct 2017

You Are What You Eat: Gastronomy & Geography Of Southern Spain, Katherine F. Perry

The Catalyst

Using empirical and numeric data, this study explores the use of food as a proxy to understand the cultural-historical geography of southern Spain. After spending three months in Granada, Spain, I compiled the most commonly used thirty-five ingredients from a selection of Spanish cookbooks and contextualized them within the broader history of Spain. The elements of traditional Andalucían cooking fit into three primary chapters of Iberian history: Roman occupation, the Moorish invasion beginning in the 8th century, and the Columbian exchange, or the exchange of goods that took place between the Americas and Old World following European discovery of …

All In - And More! Gambling In The James Bond Films, Pauliina Raento Oct 2017

All In - And More! Gambling In The James Bond Films, Pauliina Raento

UNLV Gaming Research & Review Journal

Scholarly analysis of gambling in the James Bond films is rare, despite the multitude of topics in Bondology and the fictional agent’s global fame. The odd commentary in gambling scholarship criticizes the franchise from the perspective of harm prevention. This article counters both groups of scholars with a qualitative interpretation of Bond’s gambling habits and the role of gambling and risk taking in the film series. A basic toolkit of visual methodologies is applied to the 24 EON-produced Bond films released in 1962–2015. The examination shows the critical importance of gambling to character identity, power hierarchies and communication, atmosphere, and …

Researching Peers And Disaster Vulnerable Communities: An Insider Perspective, Stern M. Kita Oct 2017

Researching Peers And Disaster Vulnerable Communities: An Insider Perspective, Stern M. Kita

The Qualitative Report

Conducting research among peers and communities that a researcher also serves may be both daunting and rewarding. Researching peers may make the researcher feel uncomfortable raising certain questions that are sensitive or that could be construed to be testing their competencies. This paper is inclined more towards showing that it is advantageous to be an insider, whose position can facilitate collection of information that could not have been accessed, or revealed to an outsider. The paper reports on fieldwork conducted in a low-income country in Sub-Sahara Africa as part of a doctoral study with communities affected by disasters and those …

The Political Cost? Religious Segregation, Peace Walls, And House Prices, John A. Mccord, Michael J. Mccord, Peadar T. Davis, Martin E. Haran, Sean Macintyre Oct 2017

The Political Cost? Religious Segregation, Peace Walls, And House Prices, John A. Mccord, Michael J. Mccord, Peadar T. Davis, Martin E. Haran, Sean Macintyre

Peace and Conflict Studies

The longstanding issue of discrimination and segregation in housing markets has enveloped housing market analysis and particularly the understanding of house price determination. Whilst the relationship of segregation in residential space is diverse and encompasses numerous taxonomies, in Northern Ireland, the high level of market segregation is compounded by the addition of tactile barriers such as Peace walls. The existence of these tactile barriers serves to physically segregate communities and have the capacity to prevent the restoration of normal community interactions and market processes. This paper attempts to quantify and measure the disamenity implications and costs of these hard structures …

Using Osgeo Solutions For Local Development Systems Implementation. The Experience For The Northern Region Of Costa Rica, López-Villegas Oscar, Víquez-Acuña Oscar, Víquez-Acuña Leonardo

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Although some general definitions classify Spatial Data Infrastructures (SDI) as technological standards, institutional and even political agreements, which allow the discovery and use of geospatial information by users for different purposes [Kuhn 2005], computationally this platforms are valuable data repositories that should reach people efficiently and effectively for analysis and decision making on issues of collective interest. Costa Rica has several SDIs experiences at national level (SNIT - http://www.snitcr.go.cr), regional level (IDEHN - http://www.idehn.tec.ac.cr) or local/cantonal level (IDESCA - http://idesca.cr). Those infrastructures can facilitate access between geospatial information managers and their consumers through the implementation of particular software applications. The …

Kadaster Data Platform - Overview Archicture, Erwin Folmer, Wouter Beek

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The Dutch Cadastre is publishing its geospatial data assets as Linked Open Data through the Kadaster Data Platform (KDP). The KDP supports the following three Linked Data browsing paradigms: (1) graph navigation, (2) hierarchical browsing, and (3) faceted browsing. Graph navigation uses the graph-shape of the RDF datamodel, to display concepts and instances as nodes, and properties between them as edges between those nodes. Graph navigation works well for explorative browsing. For graph navigation the KDP uses LODView (http://lodview.it), an existing OSS. Hierarchical browsing uses the tree structure of the concept hierarchy in order to display the various classes and …
