    Development of NO2 and NOx land use regression models for estimating air pollution exposure in 36 study areas in Europe: the ESCAPE project2013In: Atmospheric Environment, ISSN 1352-2310, E-ISSN 1873-2844, Vol. 72, p. 10-23Article in journal (Refereed)
    Abstract [en]

    Estimating within-city variability in air pollution concentrations is important. Land use regression (LUR) models are able to explain such small-scale within-city variations. Transparency in LUR model development methods is important to facilitate comparison of methods between different studies. We therefore developed LUR models in a standardized way in 36 study areas in Europe for the ESCAPE (European Study of Cohorts for Air Pollution Effects) project.

    Nitrogen dioxide (NO2) and nitrogen oxides (NOx) were measured with Ogawa passive samplers at 40 or 80 sites in each of the 36 study areas. The spatial variation in each area was explained by LUR modeling. Centrally and locally available Geographic Information System (GIS) variables were used as potential predictors. A leave-one out cross-validation procedure was used to evaluate the model performance.

    There was substantial contrast in annual average NO2 and NOx concentrations within the study areas. The model explained variances (R2) of the LUR models ranged from 55% to 92% (median 82%) for NO2 and from 49% to 91% (median 78%) for NOx. For most areas the cross-validation R2 was less than 10% lower than the model R2. Small-scale traffic and population/household density were the most common predictors. The magnitude of the explained variance depended on the contrast in measured concentrations as well as availability of GIS predictors, especially traffic intensity data were important. In an additional evaluation, models in which local traffic intensity was not offered had 10% lower R2 compared to models in the same areas in which these variables were offered.

    Within the ESCAPE project it was possible to develop LUR models that explained a large fraction of the spatial variance in measured annual average NO2 and NOx concentrations. These LUR models are being used to estimate outdoor concentrations at the home addresses of participants in over 30 cohort studies.

    Life course preferences, sibling ties and the geographical dispersion of sibling networks2013In: Population, Space and Place, ISSN 1544-8444, E-ISSN 1544-8452, Vol. 19, no 5, p. 594-609Article in journal (Refereed)
    Abstract [en]

    Using Swedish register data, we analyse how life course preferences and sibling ties are related to the geographical dispersion of siblings. We argue that life course preferences and siblings ties are influenced by siblings' socio-demographic characteristics, by similarities and differences between them, and by their family background. The measurement of geographical dispersion, the nearest neighbour index, allows us to go beyond dyadic relationships and investigate entire networks. Results from the OLS regression analysis show that life course preferences are related to the dispersion of siblings, and that differences between siblings are associated with a greater geographical dispersion than similarities are. Sibling ties developed during childhood also seem to be associated with the dispersion of sibling networks.

    Impact of precautionary behaviors during outbreaks of pandemic influenza: modeling of regional differences2009In: AMIA Annual Symposium proceedings Archive, ISSN 1942-597X, Vol. 2009, p. 163-7Article in journal (Refereed)
    Abstract [en]

    Using time geographic theory for representation of population mixing, we set out to analyze the relative impact from precautionary behaviors on outbreaks of pandemic influenza in Europe and Asia. We extended an existing simulator environment with behavioral parameters from a population survey to model different behaviors. We found that precautionary behaviors even among a minority of the population can have a decisive effect on the probability of the outbreak to propagate. The results also display that assumptions strongly influences the outcome. Depending on the interpretation of how many "children" are kept from "school", R(0) changes from a range where outbreak progression is possible to a range where it is improbable in both European (R(0)=1.77/1.23) and Asian (R(0)=1.70/1.05) conditions. We conclude that unprompted distancing can have a decisive effect on pandemic propagation. An important response strategy can be to promote voluntary precautionary behavior shown to reduce disease transmission.

    Employability of Swedish student teacher alumni2008In: Teacher education policy in Europe: a voice of higher education institutions / [ed] Brian Hudson, Pavel Zgaga, Umeå: Institutionen för tillämpad utbildningsvetenskap, Umeå universitet , 2008, p. 157-181Chapter in book (Other academic)
    Abstract [en]

    In recent years, “employability” has become an increasingly central concept in higher education, in no small part since it constitutes an important aspect of the Bologna Process. The project “Teachers’ employability” is a project carried out on behalf of the Faculty of Teacher Education at Umeå University – one of the major providers of teacher education in Sweden – and is a part of a broader university effort to evaluate and increase employability. The aim of the project is to examine the situation of the university’s student teachers after graduation, as well as to find out how the former students and their employers view their education.

    The study is based on the longitudinal individual database ASTRID, questionnaires and interviews. This paper reports findings from the project, focusing on 1) employment situation, income development and mobility patterns of recent alumni (class of 2000) and 2) primary employers’ (school leaders) view of the quality and usefulness of the present teacher education curriculum. While employability is generally high, there are significant differences in career paths and income development, depending on for instance type of degree and place of residence. The interviews with school leaders reveal that although the present curriculum is perceived to have certain general limitations, it is viewed as more suited for pre-school rather than comprehensive school and gymnasium teacher education.

    Proximity, accessibility and choice: a matter of taste or condition?2012In: Papers in regional science (Print), ISSN 1056-8190, E-ISSN 1435-5957, Vol. 91, no 1, p. 65-84Article in journal (Refereed)
    Abstract [en]

    Drawing on a combination of register data and travel survey data, this research explores changes in the accessibility to different amenities for the Swedish population between 1995 and 2005, as well as the reasons behind the changes: redistribution of either amenities or the population. Overall, proximity has increased concerning most of the amenities during the period. However, despite decreasing 'potential' distances, actual travel distances are growing longer due to, for example, an increasing selectivity in preferences. An analysis of the accessibility development for service amenities shows that restructuring within the service sector is the main cause of the changes, and to a lesser extent population redistribution.

    Coordinated care planning for elderly patients using videoconferencing2005In: Journal of Telemedicine and Telecare, ISSN 1357-633X, Vol. 11, no 2, p. 85-92Article in journal (Refereed)
    Abstract [en]

    We studied the transfer of information during coordinated care planning between a university hospital and a local health care centre/social welfare department about 35 km away. During a seven-month study period, 10 sessions were conducted by videoconferencing and seven sessions were conducted by face-to-face conferencing. Videoconferencing reduced the time required for each coordinated care-planning session from an average of 60 to 45 min. There was also an increase in the number of participating professional categories. Travel time for the staff in the face-to-face group was 60-180 min each. Use of a care-planning report during the sessions resulted in improved quality of documentation, which contributed to better care following discharge. The technical problems that occurred did not detract from the beneficial experience of participating. Interviews with next of kin showed that they had been able to influence the content of the care during the care-planning sessions. Videoconferencing proved useful in coordinated care planning. It resulted in time saved due to reduced travel time, participation by more staff categories and an enhancement of the documentation quality.

    Abstract [en]

    In a world of changing demographical patterns, tools for keeping track of these changes are of great importance. Different regions are in different stages of the demographic transition and are affected differently of migration patterns. A tool to project the demographic development at a regional level is therefore of great importance. This article we discusses the demographic development in the county Västerbotten in Sweden and in that context why and how a micro simulation model can be used for these purposes.

    Statistik i geografi: Slutrapport av pedagogiskt projekt2010Report (Other academic)
    Abstract [sv]

    Statistik ingår som ett viktigt hjälpämne i andra akademiska ämnen som använder kvantitativa data, till exempel kulturgeografi. Kulturgeografi har vidare betydande inslag av användning av Geografiska informationssystem (GIS), där det finns stora beröringsytor med statistik. En integrering av områdena geografi och statistik kan således ge studenterna stort mervärde. Det innebär ofta en pedagogisk utmaning att förmedla statistisk kunskap till studenter som i huvudsak har sin bakgrund inom ämnen som innehåller lite kontakt med statistiska tankegångar. Detta projekts huvudsyfte har varit att utveckla en pedagogisk ansats som är lämplig i denna situation. Projektet har i första hand genomförts inom ramen för en kurs på avancerad nivå, där statistik och geografi integrerats och lärts ut med en casebaserad ansats.

    Impacts on air pollution and health by changing commuting from car to bicycle2017In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 584-585, p. 55-63Article in journal (Refereed)
    Abstract [en]

    Our study is based on individual data on people's home and work addresses, as well as their age, sex and physical capacity, in order to establish realistic bicycle-travel distances. A transport model is used to single out data on commuting preferences in the County Stockholm. Our analysis shows there is a very large potential for reducing emissions and exposure if all car drivers living within a distance corresponding to a maximum of a 30 min bicycle ride to work would change to commuting by bicycle. It would result in > 111,000 new cyclists, corresponding to an increase of 209% compared to the current situation.

    Mean population exposure would be reduced by about 7% for both NOx and black carbon (BC) in the most densely populated area of the inner city of Stockholm. Applying a relative risk for NOx of 8% decrease in all-cause mortality associated with a 10 μg m− 3decrease in NOx, this corresponds to > 449 (95% CI: 340–558) years of life saved annually for the Stockholm county area with 2.1 million inhabitants. This is more than double the effect of the reduced mortality estimated for the introduction of congestion charge in Stockholm in 2006. Using NO2 or BC as indicator of health impacts, we obtain 395 (95% CI: 172–617) and 185 (95% CI: 158–209) years of life saved for the population, respectively. The calculated exposure of BC and its corresponding impacts on mortality are likely underestimated. With this in mind the estimates using NOx, NO2 and BC show quite similar health impacts considering the 95% confidence intervals.

    Abstract [sv]

    I denna studie ställs frågan om vilka lokala spridningseffekter investeringen i ett slutförvar för använt kärnbränsle kan komma att få. För närvarande pågår platsundersökningar i Östhammar och Oskarshamn och slutförvaret kommer med stor sannolikhet att byggas i någon av dessa kommuner. Genomförandet av slutförvarsprojektet består av ett flertal olika investeringar vars lokaliseringsförutsättningar skiljer sig åt. Förutom slutförvaret för använt kärnbränsle ingår även utbyggnad av SFR (Slutförvar för radioaktivt driftavfall) och byggandet av en inkapslingsanläggning och en "kapselfabrik", för montering av kapslar. Utbyggnaden av SFR måste ske i Östhammar då SFR redan finns där och inkapslingsanläggningen bör enligt SKB byggas i anslutning till Clab (Centralt mellanlager för använt kärnbränsle) som är förlagt till Oskarshamn. Dessa omständigheter betyder att delar av den totala investeringssumman för slutförvaret (cirka 15 miljarder kronor) redan nu går att knyta till specifika platser.

    Resultaten från en enkätundersökning visar att näringslivet i de två kommunerna skiljer sig åt med avseende på möjligheter att leverera varor och tjänster till slutförvarsinvesteringen. Vid en jämförelse mellan leverantörskapacitet och upphandlingsbehov förefaller det som om att det lokala näringslivet i Oskarshamn har en sammansättning som bättre matchar slutförvarsinvesteringens behov.

    De lokala spridningseffekterna av slutförvarsinvesteringen begränsas emellertid inte till de aktiviteter som härrör till byggnation av anläggningar. Drift och efterarbeten vid anläggningarna ger också inkomster och arbetstillfällen. Slutförvaret med sidoinvesteringar kommer att generera spridningseffekter i både Östhammar och Oskarshamn oavsett i vilken kommun slutförvaret lokaliseras. Däremot blir de ekonomiska spridningseffekterna olika på grund av skillnader i det lokala näringslivets leverantörskapacitet och förutbestämda lokaliseringar av vissa sidoinvesteringar. Analyserna antyder bland annat att de lokala spridningseffekterna blir tämligen stora i Oskarshamn om Östhammar får slutförvaret, medan effekterna i Östhammar blir ytterst begränsade om slutförvaret placeras i Oskarshamn.

    Analyzing Socio-Economic Impacts of Large Investments by Spatial Microsimulation2007In: 1st General Conference of the International Microsimulation Association: Celebrating 50 Years of Microsimulation, 2007Conference paper (Other academic)
    Abstract [en]

    In the near future, a nuclear waste repository will be located in either Östhammar or Oskarshamn, two Swedish municipalities. This is a major investment that is likely to have socio-economic implications at the local level for several decades. In order to analyze the indirect local effects of such large investments, a spatial and dynamic microsimulation model (SVERIGE 3) has been constructed. The model simulates demographic events (e.g., fertility and migration) as well as education and the labor market. In this study, the simulation model is utilized to evaluate a number of scenarios comprising various potential investments in Östhammar, one of which is the nuclear waste repository. As part of the study, the direct local effect of the investments was estimated. When running the model, the estimated direct local effects function as exogenous economic input to concerned labor market sectors. The results of the simulations indicate that investments such as the nuclear waste repository will have some economic and demographic effects. However, infrastructure projects that increase accessibility seem to generate more profound and long-lasting effects at the local level. A municipality such as Östhammar, located close the Stockholm metropolitan area, may be especially likely to benefit by such infrastructure investments.

    Spatial assimilation and native partnership: evidence of Iranian and Iraqi immigrant mobility from segregated areas in Stockholm, Sweden2013In: Population, Space and Place, ISSN 1544-8444, E-ISSN 1544-8452, Vol. 19, no 3, p. 311-328Article in journal (Refereed)
    Abstract [en]

    Studies testing ‘spatial assimilation’ are no longer restricted to traditional suburbanisation movements correlated with high education, income and exposure to the ‘majority’ population. Instead, greater emphasis is now being placed on other ‘cultural’ and ‘social’ aspects associated with assimilation and different patterns of movements. While these ideas have remained dominant in North America, fewer studies have tested their applicability in European contexts. This paper addresses this by examining the spatial mobility of Iranian and Iraqi immigrants from segregated areas within Stockholm County, Sweden. By using register data for individuals for the years 2001 and 2007, binary logistic regressions reveal how significant differences emerge between those who move and those who stay, particularly for human capital (education) prior to movement and social capital (having a ‘Swedish’ partner) after movement. This raises important questions for future research dealing with issues of integration, segregation and mobility.

    Assessing ozone exposure for epidemiological studies in Malmö and Umeå, Sweden2014In: Atmospheric Environment, ISSN 1352-2310, E-ISSN 1873-2844, Vol. 94, p. 241-248Article in journal (Refereed)
    Abstract [en]

    Ground level ozone [ozone] is considered a harmful air pollutant but there is a knowledge gap regarding its long term health effects. The main aim of this study is to develop local Land Use Regression [LUR] models that can be used to study long term health effects of ozone. The specific aim is to develop spatial LUR models for two Swedish cities, Umea and Malmo, as well as a temporal model for Malmo in order to assess ozone exposure for long term epidemiological studies. For the spatial model we measured ozone, using Ogawa passive samplers, as weekly averages at 40 sites in each study area, during three seasons. This data was then inserted in the LUR-model with data on traffic, land use, population density and altitude to develop explanatory models of ozone variation. To develop the temporal model for Malmo, hourly ozone data was aggregated into daily means for two measurement stations in Malmo and one in a rural area outside Malmo. Using regression analyses we inserted meteorological variables into different temporal models and the one that performed best for all three stations was chosen. For Malmo the LUR-model had an adjusted model R-2 of 0.40 and cross validation R-2 of 0.17. For Umea the model had an adjusted model R-2 of 0.67 and cross validation adjusted R-2 of 0.48. When restricting the model to only including measuring sites from urban areas, the Malmo model had adjusted model R-2 of 0.51 (cross validation adjusted R-2 0.33) and the Umea model had adjusted model R-2 of 0.81 (validation adjusted R-2 of 0.73). The temporal model had adjusted model R-2 0.54 and 0.61 for the two Malmo sites, the cross validation adjusted R-2 was 0.42. In conclusion, we can with moderate accuracy, at least for Umea, predict the spatial variability, and in Malmo the temporal variability in ozone variation.

    Change or continuity?: Evolution of residential and workplace segregation in the Stockholm metropolitan region2011Conference paper (Other academic)
    Abstract [en]

    The origins of immigrants coming to Sweden as well as their lifestyles and labour market skills have changed substantially since the early 1990s. The last decades have also resulted in a gradual transition of the Swedish economy from industrial to more service oriented (activities relatedto ‘the new economy’). These two processes inevitably contributed to the pace of segregation in major urban regions of Sweden, regions that have been at the forefront of economic change and that have remained the main destination of many immigrants. So far, the majority of studies on segregation in Sweden have been limited to research the residential dimension only. Yet, it should be emphasised that cities contain clusters of jobs and people and that these clusters together form the socio-economic fabric of urban regions. This paper thus adopts a dynamic approach to exa- mine the evolution of residential and workplace segregation in the ethnically diverse Stockholm Metropolitan Region. Referring to the recent advancements in segregation studies we define the phenomenon of segregation as both process and pattern, and scrutinize them respectively.

    Changing patterns of residential and workplace segregation in the Stockholm metropolitan area2015In: Urban geography, ISSN 0272-3638, E-ISSN 1938-2847, Vol. 36, no 7, p. 969-992Article in journal (Refereed)
    Abstract [en]

    Immigrant–native segregation is present in the spaces in which individuals from different ethnic/racial groups practice their everyday lives; interact with others and develop their ethnic, social and spatial networks. The overwhelming majority of academic research on immigrant segregation has focused on the residential domain, thus largely overlooking other arenas of daily interaction. The present study contributes to the emerging literature on immigrant residential and workplace segregation by examining changes in patterns of residential and workplace segregation over time. We draw our data from the Stockholm metropolitan region, Sweden’s main port of entry for immigrants. The results suggest a close association between residential and workplace segregation. Immigrant groups that are more segregated at home are also more segregated in workplace neighborhoods. More importantly, we found that a changing segregation level in one domain tends to involve a similar trend in the other domain.

    Modell för beräkning av bensen- och 1,3-butadienhalter i omgivningsluft utifrån geografisk information om bland annat biobränsleeldning och trafik2012Report (Other academic)
    Abstract [sv]

    Luftföroreningar är ett känt folkhälsoproblem i tätorter där trafiken oftast är den största enskilda emissionskällan. Det finns dock andra källor som lokalt kan ge upphov till höga luftföroreningshalter och en sådan är småskalig biobränsleeldning. För att begränsa hälsoeffekterna av luftföroreningar finns normvärden reglerade i lagstiftning, och övervakningen av dessa kan ske via mätningar eller olika typer av beräkningar.

    Syftet med projekt har varit att tillämpa en typ av statistisk beräkningsmodell, ”Land Use Regression (LUR)”, för att predicera halterna av luftföroreningarna bensen och 1,3-butadien i ett antal tätorter med hög andel småskalig biobränsleeldning i och omkring Umeå.

    Principen för en LUR-modell är att först förklara variationen i luftföroreningshalter mellan ett begränsat antal mätpunkter med skillnader i geografiska variabler, som t.ex. populationsdensitet och trafikflöde inom olika radier runt respektive mätplats. Sedan kan modellen användas för att beräkna halten i många fler punkter. I denna studie har bensen och 1,3-butadien mätts vid tre tillfällen på 39 olika mätpunkter. Geografisk information har samlats in för respektive mätpunkt, och innefattar bland annat trafikvariabler men även uppgifter om biobränsleeldning baserat på uppgifter från sotarregister. LUR-modellen har byggts upp i enlighet med den procedur som finns beskrivet inom ett stort europeiskt forskningsprojekt, ESCAPE.

    Rapporten visar att det är möjligt utifrån geografiska variabler att predicera halten bensen och 1,3-butadien i en given punkt med acceptabel precision. Resultaten visar också att befolkningstäthet tillsammans med småskalig biobränsleeldning och trafik är de variabler som gemensamt är viktigast för årsmedelhalten bensen och 1,3-butadien.

    Denna typ av modell är således tillämpbar för att kartlägga och predicera halter av bensen och 1,3-butadien i områden med småskalig biobränsleeldning. Modellen kan även användas för att studera betydelsen av nyetablering av småskalig biobränsleeldning för halten bensen och 1,3-butadien inom t.ex. ett bostadsområde.

    Neighborhood conditions and celiac disease risk among children in Sweden2014In: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 42, no 7, p. 572-580Article in journal (Refereed)
    Abstract [en]

    Aim: To investigate celiac disease (CD) clustering at different geographical levels and to examine the association between neighborhood demographic and socioeconomic conditions and the risk of neighborhood CD.

    Methods: We included 2080 children diagnosed with CD between 1998 and 2003, identified from 43 of the 47 reporting hospitals in Sweden. A total of 8036 small area market statistics (SAMS) areas were included; these were nested in 253 municipalities that were further nested into eight ‘nomenclature of territorial units for statistics’ (NUTS) 2 regions. We performed multilevel logistic regression analyses.

    Results: We found the highest geographical variation in CD incidence at the municipality level, compared to the region level. The probability of having CD increased in the statistical areas of (SAMS) areas with higher average annual work income, with an odds ratio (OR) of 2.24 and 95% CI of 1.76–2.85. Reduced CD risk in neighborhoods was associated with higher average age (OR 0.96; 95% CI 0.95–0.97), higher proportion of residents with a university education (OR 0.98; 95% CI 0.97–0.99), and higher level of industrial and commercial activity (OR 0.59; 95% CI 0.44–0.82). We found no significant association between CD risk and population density, proportion of Nordic to non-Nordic inhabitants, nor share of the population with only a compulsory education.

    Conclusions: Neighborhood composition influences CD risk. This is one of the first attempts to identify factors explaining geographical variation in CD.

    Impact of residential mobility on exposure assessment in longitudinal air pollution studies: A sensitivity analysis within the ESCAPE project2012In: Scientific World Journal, ISSN 1537-744X, E-ISSN 1537-744X, Vol. 2012, p. 125818-Article in journal (Refereed)
    Abstract [en]

    Exposure misclassification in longitudinal studies of air pollution exposure and health effects can occur due to residential mobility in a study population over follow-up. The aim of this study was to investigate to what extent residential mobility during follow-up can be expected to cause exposure misclassification in such studies, where exposure at the baseline address is used as the main exposure assessment. The addresses for each participant in a large population-based study (N>25,000) were obtained via national registers. We used a Land Use Regression model to estimate the NOx-concentration for each participant’s all addresses during the entire follow up period (in average 14.6 years) and calculated an average concentration during follow up. The Land Use Regression model explained 83% of the variation in measured levels. In summary, the NOx concentration at the inclusion address was similar to the average concentration over follow-up with a correlation coefficient of 0.80, indicating that air pollution concentration at study inclusion address could be used as indicator of average air pollution concentrations over follow-up. The differences between an individual´s inclusion and average follow-up mean concentration was small, and seemed to be non-differential with respects to a large range of factors and disease statuses, implying that bias due to residential mobility was small.

    Socio-economic determinants of divorce in Sweden 1960-19652014In: Social science history, ISSN 0145-5532, E-ISSN 1527-8034, Vol. 38, no 2, p. 127-153Article in journal (Refereed)
    Abstract [en]

    During the 1960s in Sweden, socio-economic differentials decreased sharply at the same time as the labor force participation of married women and aggregate divorce rates increased more rapidly than during any other period of the twentieth century. The aim of this paper is to investigate how the socio-economic composition of the couple influenced the probability of divorce during this period of rapid restructuring. The study uses a large dataset covering the entire married population of Sweden in 1960 and applies a binary model whereby the couples are analyzed as units rather than separate individuals to model divorce during the period 1960-1965. The main results show that the equalization process between genders and social classes during this period contributed to the decrease in marital stability. Dual-provider families exhibit substantially higher probabilities of divorce as compared to traditional single-provider families. We also find that the socio-economic gradient of divorce had become negative by the early 1960s and that couples with low socio-economic status contributed more to the increase in divorce than did couples in the higher strata. A difference between the results reached in this study and those from divorce research covering later decades is that children do not reduce the probability of divorce when the wife's labor force participation is controlled for. The results indicate that the determinants of divorce have varied across different phases of the divorce transition during the twentieth century and that a historical perspective is necessary if we are to understand the long-term process that has produced current marital behavior.

    Geographical distance between children and absent parents in separated families2012In: Geografiska Annaler. Series B, Human Geography, ISSN 0435-3684, E-ISSN 1468-0467, Vol. 94, no 3, p. 239-253Article in journal (Refereed)
    Abstract [en]

    In recent decades, the share of traditional nuclear-family households has decreased in most Western countries, resulting in an increase in the proportion of children living in other forms of household constellations. How children with an absent parent or vice versa arrange their life and relations is partly a matter of physical distance between them. The aim of the study is to analyse the geographical distance between children and absent parents, that is, parents living in another household. The study is a cross-sectional study based on register data comprising all children in Sweden in 1990, 1995, 2000 and 2005. Using descriptive statistics and ordinary least squares (OLS) regression analysis, we examine the development and determinants of the distance between children and absent parents. OLS regression is employed in order to clarify how the distance relates to the age of the child, as well as demographic and socio-economic characteristics of the present and absent parents. The results show that while the share of children living with only one parent has increased over time, the average distance between children and absent parents has decreased. The distance between children and absent parents is strongly related to the sex of the absent parent and the age of the child. Absent mothers tend to live closer to their children compared with absent fathers, and the younger the children are, the shorter the distance to the absent parents. Among other factors that influence the distance are remarriage and having a child with another parent, both of which contribute to increasing distances between children and absent parents.

    Spatial diffusion of telemedicine in Sweden2003Doctoral thesis, monograph (Other academic)
    Abstract [en]

    “Telemedicine” denotes medicine at a distance using telecommunications and information technologies. The aim of the thesis is to reveal determinants and outcomes of telemedicine diffusion—that is, the spread of telemedicine in time and space. Telemedicine is examined both at the national level and in a regional case study. At the national level, quantitative methodology is utilized to analyze the emergence of health care facilities using telemedicine to receive medical assistance. The regional case study examines the diffusion and outcomes of telemedicine networks in Northern Sweden based on non-quantitative data sources.

    The first telemedicine applications in Sweden emerged between hospitals in southern Sweden in the 1970s. It was in the 1990s, however, that the practice of telemedicine took off on a larger scale. By the year 2000, the number of remote sites was quite evenly distributed across the country and between specialist and primary care facilities. In northern Sweden, telemedicine was first implemented in the mid-1980s, and is now carried out in all counties in the region. The telemedicine networks in northern Sweden primarily concern teleradiology, general telemedicine, and telepathology. Commonly, telemedicine is carried out within counties in hierarchical hub and spoke-type networks connecting specialist and primary care facilities.

    The study shows that existing telemedicine facilitates its further diffusion at the regional level, but shows a lack of the obvious neighborhood effect that could be expected in light of many previous diffusion studies and geographical diffusion theory. The health care system in Sweden is characterized by a high degree of regional autonomy. Contacts between medical staff, and thus dissemination of information and opinions concerning telemedicine, are therefore likely to be more prevalent within than between the regional health care organizations. The health care organizations are also decision-making bodies with different telemedicine policies. In addition, already implemented telemedicine programs tend to expand within the health care organization in which they originated.

    Although no traditional neighborhood effect to speak of can be noticed in Swedish telemedicine diffusion, distance matters in the diffusion process in a quite different respect. The study shows that health care facilities located far from more specialized care are especially likely to adopt telemedicine. Another local factor, facility size, is also positively correlated with telemedicine diffusion. This correlation between facility size and telemedicine adoption, as well as the circumstance that the diffusion process started with, and has progressed the furthest in, specialist care, suggest that the diffusion of telemedicine exhibits hierarchical characteristics.

    The development of telemedicine technology significantly influences the rate of telemedicine diffusion. In a simulation of the diffusion process, it is shown that—given that computers and information technology continue to develop according to the present trend—there will be a significant increase in the number of primary care facilities functioning as remote telemedicine sites during the first decade of the 21st century.

    Place-based social contact and mixing: a typology of generic meeting places of relevance for infectious disease transmission2017In: Epidemiology and Infection, ISSN 0950-2688, E-ISSN 1469-4409, Vol. 145, no 12, p. 2582-2593Article in journal (Refereed)
    Abstract [en]

    This study aims to develop a typology of generic meeting places based on social contact and mixing of relevance for infectious disease transmission. Data was collected by means of a contact diary survey conducted on a representative sample of the Swedish population. The typology is derived from a cluster analysis accounting for four dimensions associated with transmission risk: visit propensity and its characteristics in terms of duration, number of other persons present and likelihood of physical contact. In the analysis, we also study demographic, socioeconomic and geographical differences in the propensity of visiting meeting places. The typology identifies the family venue, the fixed activity site, the family vehicle, the trading plaza and the social network hub as generic meeting places. The meeting place typology represents a spatially explicit account of social contact and mixing relevant to infectious disease modelling where the social context of the outbreak can be highlighted in light of the actual infectious disease.

    Factors shaping workplace segregation between natives and immigrants2014In: Demography, ISSN 0070-3370, E-ISSN 1533-7790, Vol. 51, no 2, p. 645-671Article in journal (Refereed)
    Abstract [en]

    Research on segregation of immigrant groups is increasingly turning its attention from residential areas toward other important places, such as the workplace, where immigrants can meet and interact with members of the native population. This article examines workplace segregation of immigrants. We use longitudinal, georeferenced Swedish population register data, which enables us to observe all immigrants in Sweden for the period 1990–2005 on an annual basis. We compare estimates from ordinary least squares with fixed-effects regressions to quantify the extent of immigrants' self-selection into specific workplaces, neighborhoods, and partnerships, which may bias more naïve ordinary least squares results. In line with previous research, we find lower levels of workplace segregation than residential segregation. The main finding is that low levels of residential segregation reduce workplace segregation, even after we take into account intermarriage with natives as well as unobserved characteristics of immigrants such as willingness and ability to integrate into the host society. Being intermarried with a native reduces workplace segregation for immigrant men but not for immigrant women.

    Pre-hire factors and workplace ethnic segregation2011Report (Other academic)
    Abstract [en]

    In addition to neighbourhoods of residence, family and places of work play important roles in producing and reproducing ethnic segregation. Therefore, recent research on ethnic segregation and contact is increasingly turning its attention from residential areas towards other important domains of daily interethnic contact. The key innovation of this paper is to clarify the role of immigrants' pre-hire exposure to natives in the residence, workplace and family domains in immigrant exposure to natives in their current workplace. The study is based on Swedish population register data. The results show that at the macro level, workplace neighbourhood segregation is lower than residential neighbourhood segregation. Our micro-level analysis further shows that high levels of residential exposure of immigrants to natives help to reduce ethnic segregation at the level of workplace establishments as well.

    Learning through contact?: The effects on earnings of immigrant exposure to native population2011Conference paper (Other academic)
    Abstract [en]

    Factors influencing immigrant labour market outcomes have received increased scholarly atten- tion lately. A recent research focus has been the effects of residential setting on labour market outcomes. This study brings a new dimension to this emerging body of research, introducing the role played by workplace composition, in addition to place of residence, in immigrant earnings. Based on Swedish longitudinal register data, OLS regression is used to examine effects of previous exposure to natives on earnings in three immigrant cohorts (1990, 1995 and 2000) five years after arrival. Besides controlling for individual characteristics and various labour market attributes, a two-step Heckman correction procedure is applied to take into account the selectivity of entering the Swedish labour market. The main finding of the study is that exposure to the native population at the workplace is more important than residential exposure for predicting immigrant earnings.
