Approximating the Length of Vehicle Routing Problem Solutions Using Complementary Spatial Information
Accurately estimating the length of Vehicle Routing Problem (VRP) distances can inform transportation planning in a wide variety of delivery and service provision contexts. This study extends the work of previous research where multiple linear regression models were used to estimate the average distance of VRP solutions with various customer demands and capacity constraints. This research expands on that approach in two ways: first, the point pat…
Rural–Urban Differences in Non-Local Primary Care Utilization among People with Osteoarthritis
The utilization of non-local primary care physicians (PCP) is a key primary care indicator identified by Alberta Health to support evidence-based healthcare planning. This study aims to identify area-level factors that are significantly associated with non-local PCP utilization and to examine if these associations vary between rural and urban areas. We examined rural-urban differences in the associations between non-local PCP utilization and area…
Rural–Urban Disparities in Realized Spatial Access to General Practitioners, Orthopedic Surgeons, and Physiotherapists among People with Osteoarthritis in Alberta, Canada
Rural Canadians have high health care needs due to high prevalence of osteoarthritis (OA) but lack access to care. Examining realized access to three types of providers (general practitioners (GPs), orthopedic surgeons (Ortho), and physiotherapists (PTs)) simultaneously helps identify gaps in access to needed OA care, inform accessibility assessment, and support health care resource allocation. Travel time from a patient's postal code to the phys…
Motivations and Methods for Replication in Geography
The article begins with a historical account of Hudson’s rural settlement theory and the various attempts to replicate Hudson’s research. Harvey’s exhortation “by our theories you shall know us” is discussed as a motivation for replication. Motivations not considered are the detection of fraud, mendacity, and incompetence, because these are the domain of reproducible research. Replication research in medicine, psychology, economics, and criminolo…
Microtargeting
Microtargeting is a market segmentation strategy (identifying submarkets of individuals and groups for marketing or political purposes) based on an individual's behavioral, geodemographic, and psychographic characteristics. It has its origins in the use of geodemographic and psychographic cluster analysis and was developed in part because of its effective use in the marketing of products and services to niche audiences and its perceived usefulnes…
Geospatial patterns of comorbidity prevalence among people with osteoarthritis in Alberta Canada

T obler's First Law of Geography
Tobler's first law (TFL) of geography was introduced into the geographical literature in an article that Waldo Tobler published in the journal Economic Geography in 1970. In this article, which described a simulation of population growth in Detroit, Tobler stated that to make his model operational he would “invoke the first law of geography: everything is related to everything else, but near things are more related than distant things.” This entr…
Gis
Geographic information systems were first formally introduced with the development of the Canada Geographic Information System (CGIS) in the early 1960s. The CGIS both benefitted from earlier conceptualizations and pioneered new software, hardware, and algorithms for handling spatial data. From the 1970s to the 1990s there was an emphasis on geographic information systems . GIS innovators John Coppock and David Rhind divided this era into: (i) a …

Maps and Beyond
In the late fifteenth and throughout the sixteenth century, European intellectual, scientific, and industrial influences manifested themselves brilliantly in the fields of geography, cartography, and printing and in improving maritime technologies. These areas of expertise came together in a fashion that made possible a rapid transference of information, in printed form, of the discoveries that Italian, Iberian, and later French, Dutch, and Engli…
Past residence outside of the United States is associated with diet quality in adults currently residing in the United States
OBJECTIVE: To evaluate healthy dietary factors in relation to prior residence outside the United States (US) among university-affiliated individuals currently residing in the US. METHODS: Current diet information was collected via a 4-day food record and residential history data were collected by in-person interview for 114 individuals. RESULTS: Residence outside of the US at any point during the interviewee's life was associated with higher diet…

Everybody Was Looking for a Good Government Job”
During the period from childhood through young adulthood individuals select the occupation that best satisfies their needs based on their values, interests, education, and environment. Arlington County, Virginia, provides an opportunity to study the impact that geography played on occupational choice for one black community during segregation. Using qualitative methods, this article explores the occupational choices of Arlington’s African America…
No-Notice Urban Evacuations
Emergency evacuations during the past decade have transitioned from landline analog to mobile digital communication devices. Over 88% of US citizens own a mobile phone, providing a tool to enable better communication between first responders and citizens in order to minimize risk to evacuees during no-notice evacuations. During an emergency, evacuees rely on social media to communicate with family, friends, and coworkers, often finding accessibil…

Southern Suburb/Northern City
Most scholarship on racial segregation in U.S. cities retraces the Great Migration, from the rural South to the urbanizing, industrializing North. Arlington County, Virginia, adjacent to the large, prosperous black community of Washington, D.C., provides a unique opportunity to study processes that transcended this dichotomy. During segregation blacks were limited to living and doing business in three of the County's 38 census tracts. Using censu…

Spatial Patterns of Subprime Mortgages by Local Banks, Nonlocal Banks, and Independents in the Continental US
Mortgage innovations and New Deal agencies facilitated lower priced loans for prime borrowers and minimum price disparities across US regions. In the 1980s deregulation removed price restrictions on banks' mortgages and also removed geographic distance restrictions on lending, opening the subprime industry. Global and local Moran indices identified interregional price disparities based upon proportions of subprime mortgage originations. A cluster…
Traffic volume and highway permeability for a mammalian community in the Canadian Rocky Mountains
We examined whether highway traffic volume changed the rates of movement (habitat permeability) for ten mammalian species in the central Canadian Rocky Mountains. Winter track count data were collected on four highways of varying traffic volume: the Trans‐Canada Highway (TCH) (14,000 annual average daily traffic [AADT]) and 1A Highway (3,000 AADT) in Banff National Park and the Highway 40 (5,000 AADT) and Smith Dorrien Trail in Kananaskis Country…
Urban Economic Participation and Survival Strategies in Ghana
The urban center has become an important arena of economic participation for increasing numbers of Sub‐Saharan Africans. Because of problems associated with censuses, economic assessment of participation rates, proportions employed, unemployed and underemployed and their temporal and spatial variations are unreliable for most countries. In addition, die relationship between changes in national economies, economic participation and survival strate…

Quantitative Methods for Investigating the Variables That Underlie Preference for Landscape Scenes
A series of quantitative methods for investigating the basis for preference for landscape scenes was applied to photographs of alpine and subalpine landscapes in Alberta. The procedure incorporates a multidimensional scaling analysis with the repertory grid technique and also employs a property vector‐fitting algorithm as an aid in interpreting the dimensional solution. The preferences of a sample group were based on three criteria. In order of i…

A Comparative Evaluation of Firms’ Behavioral Environments Based on Two Forms of Cluster Analysis
This paper utilizes hierarchical and non-hierarchical Cluster Analysis to evaluate entrepreneurs' perception of regional economic milieux, and tests hypotheses concerning differences in entrepreneurial perception within an undifferentiated population of firms and among groups of product-related firms. The attitudes of 107 manufacturers in Calgary. Alberta, Canada toward fifty statements deemed to reflect the essence of their regional manufacturin…
The Application of Cluster Analysis to Entrepreneurial Perception of Regional Economic Environments
This paper evaluates nine elements, comprised of 233 entrepreneurs' locational attitudes in two Canadian metropolitan centers, for evidence that perception of the same region differs according to metropolitan location, and that locational images are related to specific types of manufacturing activity. Hierarchical cluster analysis is used to group attitudes that entrepreneurs hold toward their regional economic environments into patterns of simil…
