  • Learning Benefits of Using 2D Versus 3D Maps: Evidence from a Randomized Controlled Experiment
  • 2013
  • Ingår i: Journal of geography. - New York : Informa UK Limited. - 0022-1341 .- 1752-6868. ; 112:3, s. 87-96

    • The traditional important role of maps used for educational purposes has gained further potential with recent advances in GIS technology. But beyond specific courses in cartography this potential seems little realized in geography teaching. This article investigates the extent to which any learning benefits may be derived from the use of such technologies. A controlled experiment was conducted to examine whether information recall is improved when cartographic information on population distribution is presented in 2D versus 3D form. The results show statistically significant differences in learning benefits between the two formats, largely in favor of 2D representation. These findings suggest that learning benefits can be derived from paying greater attention to map format in educational settings.

  • A pixel level evaluation of five multitemporal global gridded population datasets : a case study in Sweden, 1990-2015
  • 2020
  • Ingår i: Population and environment. - : Springer Science and Business Media LLC. - 0199-0039 .- 1573-7810. ; 42, s. 255-277
  • Forskningsöversikt (refereegranskat)abstract
    • Human activity is a major driver of change and has contributed to many of the challenges we face today. Detailed information about human population distribution is fundamental and use of freely available, high-resolution, gridded datasets on global population as a source of such information is increasing. However, there is little research to guide users in dataset choice. This study evaluates five of the most commonly used global gridded population datasets against a high-resolution Swedish population dataset on a pixel level. We show that datasets which employ more complex modeling techniques exhibit lower errors overall but no one dataset performs best under all situations. Furthermore, differences exist in how unpopulated areas are identified and changes in algorithms over time affect accuracy. Our results provide guidance in navigating the differences between the most commonly used gridded population datasets and will help researchers and policy makers identify the most suitable datasets under varying conditions.

  • On Distance and the Spatial Dimension in the Definition of Internal Migration
  • 2014
  • Ingår i: Annals of the Association of American Geographers. - : Informa UK Limited. - 0004-5608 .- 1467-8306. ; 104:2, s. 357-372
  • Tidskriftsartikel (refereegranskat)abstract
    • Migration is commonly defined by a temporal and a spatial dimension. It is generally agreed that these dimensions are problematic and could seriously distort understanding of migration, but data constraints have effectively obstructed further insights. This article focuses on the spatial dimension where migration is typically defined as movement across administrative borders. Borders usually serve as proxies for migration distance but the validity of such proxies is largely unknown, posing a considerable challenge to migration research. Using data for all internal migrants in Sweden, the only known country where migration distances are available in sufficient detail, we present the first accurate description of actual migration distances and investigate the relationship between actual migration distances and migration-defining boundaries. More specifically, we examine how the volumes of migration and the characteristics of migrants change when migration distances vary and when different types of migration-defining boundaries are employed. The findings show that notable shares of short-distance migrants are included almost regardless of which migration-defining boundary is employed, but migrant differentials are less affected than might be expected.

  • Towards a theory of place marketing
  • 2012
  • Ingår i: Journal of Place Management and Development. - Bingley : Emerald Group Publishing Limited. - 1753-8335 .- 1753-8343. ; 5:3, s. 223-230
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Place marketing approaches are increasingly employed by public authorities competing to attract capital. While a growing number of studies have provided valuable insights, scholars appear to be struggling to advance their theoretical understanding. This is arguably the result of failure to produce evidence-based research, excessive focus on small-scale case studies, difficulties bridging disciplinary boundaries, and reluctance to advance generalizations. To overcome these problems, we present a framework that can be used to generate empirically testable hypotheses and thereby provide a structure for research.Design/methodology/approach: A brief literature review first identifies obstacles that prevent place marketing research from making significant progress. Second, to overcome these obstacles, we identify the need to consider spatial competition for capital, which has, remarkably, been overlooked. Third, drawing on these insights, a conceptual framework is presented. Fourth, from this framework, six propositions are deduced that may enable the development of a theory of place marketing.Findings: This work first identifies the need for a more rigorous approach to the scientific study of place marketing. Second, a conceptual framework is suggested, based on spatial competition for capital. Third, we demonstrate that testable hypotheses can be deduced from the framework to provide a structure for research. Arguably, empirically testing such hypotheses would significantly advance our understanding of place marketing.Originality/value: This paper identifies a feasible way to structure future research that should interest place marketing researchers seeking a more rigorous approach to theoretical advancement.© Emerald Group Publishing Limited.

  • Clamour for glamour? City Competition for hosting the Swedish tryouts to the Eurovision Song Contest
  • 2010
  • Ingår i: Tijdschrift voor economische en sociale geografie. - Utrecht : University of Utrecht. - 0040-747X .- 1467-9663. ; 101:2, s. 111-125
  • Tidskriftsartikel (refereegranskat)abstract
    • For some time it has been argued that cities all over the world have become more entrepreneurial and increasingly competitive. Most research has focused on spectacular events in well-known metropolises, but far less is known about how smaller cities engage in competitive activities. This paper focuses on how, why and what Swedish cities hope to achieve by engaging themselves in hosting the tryouts to the Eurovision Song Contest (ESC), which provides an opportunity for a critical case study of place marketing and city competition in Sweden. The empirical material is based on interviews with stakeholders in the tryouts. Our findings show that the local authorities do not compete in the same way as suggested by the literature, but instead collaborate to a great deal. While there are various motives behind arranging a tryouts tryout, it is noted that whereas the ESC presents an opportunity for a host city to 'place itself on the map', hosting a tryout is often mainly seen as an opportunity to show the organisers of the event the city's potential for hosting other events in the future. Our findings suggest that the main outcome of hosting a tryout, an outcome that the local authorities seem content with, is having arranged a glamorous party for the local inhabitants. The paper concludes by discussing why competition was found to be less outspoken than the literature suggests.

  • Using Satellite Data on Nighttime Lights Intensity to Estimate Contemporary Human Migration Distances
  • 2017
  • Ingår i: Annals of the American Association of Geographers. - : Informa UK Limited. - 2469-4452 .- 2469-4460. ; 107:3, s. 591-605
  • Tidskriftsartikel (refereegranskat)abstract
    • © 2017 by American Association of Geographers. For well over a century, migration researchers have recognized the lack of adequate distance measures to be a key obstacle for advancing understanding of internal migration. The problem arises from the convention of spatially defining migration as the crossing of administrative borders. Because administrative regions vary in size, shape, and settlement patterns, it is difficult to tell how far movers go, raising doubts about the generalizability of research in the field. This article shows that satellite data on nighttime lights can be used to infer accurate measures of migration distance. We first use the intensity of nighttime lights to locate mean population centers that closely correspond to mean population centers calculated from actual population data. Until now, locating mean population centers accurately has been problematic, as it has required highly disaggregated population data, which are lacking in many countries. The nighttime lights data, which are freely available on a yearly basis, solve this challenge. We then show that this information can be used to accurately estimate migration distances.

  • Spatial and temporal patterns of economic segregation in Sweden’s metropolitan areas : A mobility approach
  • 2018
  • Ingår i: Environment and Planning A. - 1472-3409 .- 0308-518X. ; 50:4, s. 809-825
  • Tidskriftsartikel (refereegranskat)abstract
    • The statistical resources at hand for segregation research are usually almost exclusively confined to annual or decennial records where the only available spatial information is the individual’s place of residence. This coarse temporal periodicity and spatial resolution provides a very limited account of people’s diurnal lives. Incorporating mobility and temporal dimensions in segregation analysis is advocated within a growing body of research but there has rarely been sufficient data to make this possible. In this paper, we employ a fine-grained mobile phone dataset outlining the daily mobility of a substantial sample of the residents in Sweden’s metropolitan areas. Combining spatial trajectory data with detailed socio-economic residential statistics, we are able to study how everyday spatial mobility in cities shapes the segregation experiences of people and changes the segregation levels of places. Results indicate that while mobility alleviates segregation for some individuals, the population of a large number of areas remain highly segregated even when daily mobility is taken into account. Individuals residing or spending time in central urban areas are more exposed to individuals from other areas because of daily moves to these central places. Daytime movement to central areas also reduces segregation significantly for people from places remote from city centres but with high average levels of mobility whilst daytime segregation levels remain close to their original night-time levels in low-mobility areas in the outskirts of the cities.

  • Back to the city : internal return migration to metropolitan regions in Sweden
  • 2013
  • Ingår i: Environment and planning A. - : SAGE Publications. - 0308-518X .- 1472-3409. ; 45:10, s. 2477-2494
  • Tidskriftsartikel (refereegranskat)abstract
    • Longitudinal microdata on the Swedish population, 1990-2006, are used to examine the numbers and characteristics of internal return migrants, emphasizing Sweden's three largest cities. Our study indicates that metropolitan regions are gaining population from net return migration, which thus carries people in the same direction as does most internal migration. Evidence also indicates that returnees to metropolitan regions are more likely to stay permanently than are migrants returning elsewhere. Furthermore, return migrants to metropolitan regions are distinguished from other return migrants in ways that emphasize the advantages of these regions, higher incomes and levels of education being among the pronounced attributes. However, metro-bound returnees do not have as many children as do other return migrants.
