Blending for student engagement: Lessons learned for Moocs and beyond
The purpose of this ongoing, three-year action research study is to explore the digital challenges of student engagement in higher education within the experimental platform of blended learning. Research questions examine the role of digital innovation in supporting diverse learners, as well as building meaningful connections with technology for undergraduate teacher education students. Results from qualitative data collected through instructor j…
The association between neighborhood socioeconomic status and exposure to supermarkets and fast food outlets
Food Deserts in the Prairies? Supermarket Accessibility and Neighborhood Need in Edmonton, Canada
The U.S. and U.K. literatures have discussed “food deserts,” reflecting populated, typically urban, low-income areas with limited access to full-service supermarkets. Less is known about supermarket accessibility within Canadian cities. This article uses the minimum distance and coverage methods to determine supermarket accessibility within the city of Edmonton, Canada, with a focus on high-need and inner-city neighborhoods. The results show that…

Using the Getis Statistic to Explore Aggregation Effects in Metropolitan Toronto Census Data
In an earlier paper by the same authors (Amrhein and Reynolds 1996), the variation of the G statistic (Getis 1991; Getis and Ord 1992) was demonstrated to correlate very highly with calculated aggregation effects. In the conclusions to this earlier paper, we called for experiments with different data sets, different aggregation rules, and different definitions of the connectivity matrix. In this paper, we explore the behaviour of census data from…
Searching for the Elusive Aggregation Effect: Evidence from Statistical Simulations
The past few years have seen a resurging interest in the modifiable areal unit problem, or aggregation effects. The new evidence, however, both supports and conflicts with previous work. This paper represents the first stage in a series of numerical experiments designed to explore the nature and extent of scale and zonation effects. Results from a series of carefully controlled statistical simulations are reported. It is concluded that there defi…
The Effect of Data Aggregation on a Poisson Regression Model of Canadian Migration
A Statistics Canada data set for Canadian migration data at the census division level incorporating information on income tax for 1986 has already been presented. This matrix of 260 × 260 flows was used to calibrate a set of Poisson regression models by utilizing flows for the aggregate population. In this paper, the relatively high spatial resolution is used to test for aggregation effects as the original 260 units are combined to form fewer, sy…

Poisson Regression Models of Canadian Census Division Migration Flows
Location, Technical Change and Labour Migration in a Heterogeneous Industry
AMRHEIN C. G. and HARRINGTON J. W. Jr (1988) Location, technical change, and labour migration in a heterogeneous industry, Reg. Studies 22, 515–529. Individual firms in an industry may exhibit differences in technical capabilities, economies of scale and size. These characteristics affect the firms' decisions regarding factor use and production location. This paper explores the relations among these decisions in a setting of a single interregiona…
Simultaneous Firm and Worker Relocation and Regional Economic Performance: A Simulation Model
A Micro-simulation Model of a Spatial Labor Market
We present a model that deals with continuous space and functional regions in the form of overlapping, interacting, and constantly changing contact fields associated with the individual actors in a labor market. Simulations illustrate the results of the model, presenting individual histories of firms and workers. The model demonstrates the importance of the relative location of the firm and the employee in terms of the effort needed to construct …
Technical and Locational Evolution in a Heterogeneous Industry
This paper uses an evolutionary simulation model of technical and locational adjustment to refine concepts of labor‐ and output‐market segmentation within an industry. The simulation model focuses on differences among establishments arising from different strategic orientations. In particular, there are significant differences in establishments' likelihoods of relocation within a heterogeneous landscape. Empirically testable hypotheses are sugges…
An elementary simulation model of the job matching process within an interregional setting
Amrhein C. G. and MacKinnon R. D. (1985) An elementary simulation model of the job matching process within an interregional setting, Reg. Studies 19, 193–202. A dynamic model of a multiregional job search and migration process is developed. Heterogeneous skills of workers and skill requirements of employers give rise to a process that matches workers of different types to various job opportunities. An optimal intraregional matching requires worke…
Interregional Labor Migration and Information Flows
Interregional labor migration occurs in response to the stress existing between a worker's existing condition and the expected condition perceived to exist in an alternative region. These perceptions are formed from information received through various channels. Three channels are examined: interpersonal communication, general source information, and specific source information targeted at unemployed workers. In this process, trajectories of welf…
