In this study the Incidence function model was used to estimate occupancy levels and capacity of a landscape to sustain a metapopulation according to four different area measurement scenarios. Results from the simulations indicate that perimeter-area related measures of patch size combined with capacity could be a more important measure for estimation of population dynamics compared to a basic area measurement.

The background to the thesis is the decentralization trend which has led to the development of various forms of local radio and television in a number of countries, including Sweden. Common to all official statements regarding the emergence of local media is the theme that local media has a potential for strengthening democracy. The aim is formulated as: to what extent can investigations into audience and participation in Swedish local media be considered indicators of whether these media contribute to the generally-accepted democratic aims of society? Special attention is also given to a study of the research field of "local mass communication" i this has been achieved with the help of a bibliographical analysis of the documents listed in the NORDICOM-bibliography for the years 1975-1980. The audience and participation analysis is based upon: (a) the author's own studies from the cable-tv experiment in Kiruna 1974/75; (b) secondary analyses of studies of audience and participation in Swedish local and neighbourhood radio 1979/80; and (c) the author's own data on local radio from a study in Västerbotten in 1978. The analyses in the thesis are based on two ideal models for the democracy-media relationship - the ideal-democratic model and the critical model. The results show that there is support for both models, i.e. local broadcasting media seems to both reach low-resource people and generate participation in various forms. On the other hand, from the point of view of the critical model, it seems as if participants represent well-established groups in society. The cable-tv data also indicates that activation effects are larger among the highly-edu-cated members of the audience. Other results demonstrate that the following factors are decisive for audience structure: size of the broadcasting area, occupation, and the listener's distance from the transmitting area. Factors that are critical for participation and contact-tendency are organizational activity and previous attempts to achieve influence in community matters. / digitalisering@umu

Background: Obesity and physical inactivity rates have reached epidemic levels in Canada, but differ based on whether they are self-reported or directly measured. Canadian research examining the combined and independent effects of social and built environments on adult physical activity (PA) and body mass index (BMI) is limited. Furthermore there is a lack of Canadian studies to assess these relationships using directly measured PA and BMI. Objectives: The objectives of this thesis were to systematically compare self-reported and directly measured PA and to examine associations between neighbourhood built and social environmental factors with both self-reported and directly measured PA and overweight/obesity in adults living in Ottawa, Canada. Methods: A systematic review was conducted to identify observational and experimental studies of adult populations that used both self-report and direct measures of PA and to assess the agreement between the measures. Associations between objectively measured neighbourhood-level built recreation and social environmental factors and self-reported individual-level data including total and leisure-time PA (LTPA) and overweight/obesity were examined in the adult population of Ottawa, Canada using multilevel models. Neighbourhood differences in directly measured BMI and PA (using accelerometry) were evaluated in a convenience sample of adults from four City of Ottawa neighbourhoods with contrasting socioeconomic (SES) and built recreation (REC) environments. Results: Results from the review generally indicate a poor level of agreement between self-report and direct measures of PA, with trends differing based on the measures of PA, the level of PA examined and the sex of the participants. Results of the multilevel analyses identified that very few of the built and social environmental variables were ii significantly associated with PA or overweight/obesity. Greater park area was significantly associated with total PA in females. Greater green space was shown to be associated with lower odds of male LTPA. Factors from the social environment were generally more strongly related to male outcomes. Further to the recreation and social environment, factors in the food landscape were significantly associated with male and female PA and overweight/obesity. Results of the directly measured PA and BMI investigation showed significant neighbourhood-group effects for light intensity PA and sedentary time. Post-hoc tests identified that the low REC/high SES neighbourhood had significantly more minutes of light PA than the low REC/low SES. BMI differed between the four neighbourhoods, but the differences were not significant after controlling for age, sex and household income. Conclusions: Results of this dissertation show that the quantity of PA can differ based on its method of measurement (i.e. between self-report and direct methods) with implications for the interpretation of study findings. It also identifies that PA and BMI can differ by neighbourhood and recognizes that the relationships between neighbourhood environments and PA and body composition are complex, may be differ between males and females, and may not always follow intuitive relationships. Furthermore it suggests that other factors in the environment not examined in this dissertation may influence adult PA and BMI and that longitudinal and intervention studies are needed.

Enhancing primary care is key to the Canadian health care reform. Considered as an indicator of primary care access and quality, hospitalisations for ambulatory care sensitive (ACS) conditions are commonly reported by Canadian organisations as sentinel events signaling problems with the delivery of primary care. However, the literature calls for further research to identify what lies behind ACS hospitalisation rates in regions with a predominantly urban population benefiting from universal access to health care. A theoretical model was built and, using an ecological design, multiple regressions were implemented to identify which neighbourhood characteristics explained the socio-economic gradient in ACS hospitalisation rates observed in Ottawa. Among these neighbourhoods, healthy behaviour and - to a certain extent - health status were significantly associated with ACS hospitalisation rates. Evidence of an association with primary care accessibility was also signaled for the more rural neighbourhoods. Smoking prevention and cessation campaigns may be the most relevant health care strategies to push forward by policy makers hoping to prevent ACS hospitalisations in Ottawa. From a health care equity perspective, targeting these campaigns to neighbourhoods of low socio-economic status may contribute to closing the gap in ACS hospitalisations described in this current study. Reducing the socio-economic inequalities of neighbourhoods would also contribute to health equity.

Many health geography studies, including the Ottawa Neighbourhood Study (ONS), have faced significant challenges uncovering local variation in patterns of community health in rural areas. This is due to the fact that sparsely populated rural areas make it difficult to define neighbourhoods that are representative of the social and resource utilization patterns of the individuals therein. Moreover, rural areas yield small samples from population-based regional health surveys and this leads to insufficient sample sizes for reliable estimation of health determinants and outcomes. In response to this issue this thesis combines geographical and statistical techniques which allow for the simulation of health variables within small areas and populations within rural Ottawa. This methodological approach combines the techniques of dasymetric mapping and statistical micro-simulation in an innovative way, which will allow health geography researchers to explore health determinants and health outcomes at small spatial scales in rural areas. Dasymetric mapping is used to generate a statistical population surface over Ottawa and then estimate socio-economic (SES) variables within small neighbourhood units within rural Ottawa. The estimated SES variables are then used as correlate variables to simulate health determinant and health outcome variables form the Canadian Community Health Survey (CCHS) using statistical micro-simulation. Through this methodology, simulations of specific health determinants and outcome can be investigated at small spatial scales within rural areas. Dasymetric mapping provided neighbourhood-level population estimates that were used to re-weight as set of SES variables that were correlates with those in the Canadian Community Health Survey (CCHS). These neighbourhood-level correlates allowed microsimulation and consequent spatial exploration of prevalence for smoking, binge drinking, obesity, self-rated mental health, and the presence of two or more chronic conditions. The methodology outlined in this paper, provides and innovative way of exploring health determinants and health outcomes in neighbourhoods for which population and health statistics are not traditionally collected at levels that would allow traditional statistical analyses of prevalence.

Seit 2004 versucht die EU mit der Europäischen Nachbarschaftspolitik demokratische Werte in ihre Nachbarländer zu exportieren. Adressaten sind Länder der Mittelmeerunion und Länder des postsozialistischen Europa, die in der Östlichen Partnerschaft zusammengefasst sind. Als außenpolitisches Instrument bietet die Nachbarschaftspolitik eine Alternative zur Erweiterungspolitik. In erster Linie sollen negative Entwicklungen wie illegale Migration, organisierte Kriminalität, grenzübergreifende Umweltzerstörungen und ethnische Konflikte abgewehrt werden. Die Studie analysiert Externalisierung, Sozialisierung und Imitation als Mechanismen des Europäisierungsprozesses und untersucht im Rahmen einer empirischen Prozessanalyse am Beispiel der Ukraine, welche der von der Europäischen Union angewandten Mechanismen den größten Erfolg für eine Normenadaption bedeuten.

This study identifies the extent to which neighbourhood socioeconomic trends are related to intentional and unintentional child injuries in Toronto, Ontario. Children living in lower socioeconomic status (SES) neighbourhoods have often been found to face a higher injury death and morbidity rate than more well‐off children. A likely explanation is an increase in the unequal exposure to injury-promoting environments on the basis of the income polarization (a declining middle income group). However, the strength of the inverse relationship between SES and injury is related to a number of factors, including the SES indicator chosen by the researcher. Hence, a goal of the study is to determine whether neighbourhood socioeconomic trends toward income polarization have predictive power in explaining variation in injury rates in young children aged 0-6, over and above more typical measures of SES and neighbourhood disadvantage. Census data were used to determine socioeconomic trends. Neighbourhoods (census tracts) were divided into three distinct categories based on neighbourhood change in average individual income: neighbourhoods that have been improving, declining, and those displaying mixed trends. This analysis of neighbourhoods was merged with geo-coded hospital-based emergency department data to calculate rates of overall injuries, falls, burns and poisoning. The predictive power of neighbourhood socioeconomic trends on injury was compared to more typical neighbourhood disadvantage measures such as income (high, medium, low), neighbourhood employment rates, education levels, and housing quality from the 2006 census. Socioeconomic trends contributed significantly to injury outcomes, but the contribution of other neighbourhood disadvantage indicators was higher. Housing in need of repair and individuals with no university degree in a neighbourhood were positively correlated with three of four outcomes. A high immigrant population in a neighbourhood was negatively correlated with three of four outcomes. Neighbourhood socioeconomic trends had slightly more predictive power than the more typical measure of SES (high, medium or low income). Researchers should carefully consider their socioeconomic status measures when predicting injury outcomes.

A case study of Vancouver’s West End neighbourhood examines the cultural, structural, economic and political impacts of a glbtt (gay, lesbian, bisexual, transgender, and two-spirited) community and a gay urban village on its city. This work also queries the role of municipal government in the regulation and maintenance of the social composition and identity of a neighbourhood. Finally, the future of gay urban villages is discussed as their role in promoting solidarity and safety transitions toward a commercial and nodal one. This research involved three local key informant interviews and nine community residents who participated as photographers in a community visual analysis. Results unveiled a neighbourhood intrinsically well suited to serving a transient gay male community with an increasing dispersion of the identifying demographic. For the foreseeable future the significance of the Davie Village in the socio-sexual landscape of Vancouver appears secure through the nodal nature of gay retail, bars and services, reinforced by business interests. As an urban typology supporting a comparatively young glbtt culture, the gay urban village plays a unique role in the city, providing spaces of experimentation and invention — a stage for new systems of cultural (ex)change to emerge. / October 2007
