The Effects of Urban Rapid Rail Transit on Gentrification in Canadian Urban Centres

Throughout the second half of the 20th century theories attempting to explain the phenomenon of gentrification have been pervasive among studies of the changing social structures of urban centres in Europe and North America. Gentrification is defined as a process whereby higher income households move into what were previously working class neighbourhoods, resulting in either direct or indirect displacement of working class households, and ultimately transforming the social character of the neighbourhood. There has been contentious debate over the definition of gentrification, but but through its evolution and adaptation to new contexts it has remained a popular topic among scholars in urban planning. Among the studies and papers published, there are many that show that the process is not only driven by individual actors', but it is also a process deeply affected by government interests and objectives and therefore by public investments. The consequences of the process are still debated; some hail the process as a boost for everyone, (e.g. Duany, 2001), while others assert that gentrification limits accessibility to urban space for lower-income, working-class households, often with already reduced options in terms of housing, and ultimately contributes to creating increasingly socially polarized urban spaces (Marcuse, 1986; Newman and Wyly, 2006). Keeping a necessarily critical perspective in mind, this study identifies the onset of gentrification in Canadian cities and links this process to an element of urban infrastructure essential to cities; transit. The objective of this research is not only to see what the effects of the implementation of transit are on gentrification when it is initially implemented, but also to look at the impacts of transit over time on the gentrification of surrounding neighbourhoods. In the gentrification literature there are a number of articles that make mention of the influential role of accessibility, and transit, on the process of gentrification. The relationship between neighbourhood changes and the implementation and upgrading of transit infrastructure, has, as of yet, not been clearly established. Though transit has long been recognized as having important connections to changes in land-use in the areas surrounding it, there have been few studies that attempt to explore, explicitly, the connections between the implementation of rail transit infrastructure and the process of gentrification in the surrounding metropolitan area. Additionally the few studies that do exist that explicitly address the relationship between transit and gentrification do not adhere to the conventional definition of gentrification according to the literature. The hypothesis of this project is that the implementation of rapid rail transit contributes to the gentrification of surrounding neighbourhoods and may result in the displacement of lower-income households, who would have the greatest marginal benefit from access to transit. This study presents data and analysis in order to assess the hypothesis using a number of indicators of gentrification and covering a study period long enough to capture the effects of major urban rapid rail transit as it has been implemented and upgraded in Canadian cities in the 20th century. This study will specifically address the effects of rail transit infrastructure on gentrification in Montreal, Toronto and Vancouver

Recent Issues in Legal Education

Six issues in legal education, much discussed recently, were posed by the Editors of this Review to leading legal educators. These questions were and are frankly difficult and controversial, but their answers are important to our system of legal education and to our society. Capsule answers given by these distinguished legal educators are believed to be interesting and significant. Each is a personal rather than a representative opinion. Brief answers such as these, of course, are not expected to be, nor do they pretend to be, complete or profound. Their purpose is to indicate succinctly the approach of outstanding American opinion makers to difficult problems of legal education

Experience of living with cancer and comorbid illness: protocol for qualitative systematic review

Introduction There is an increasing number of people living with and beyond cancer, whose experience is further complicated by additional long-term health conditions in the context of an ageing population. The supportive care needs of this growing patient group should be recognised and addressed. There is a need to explore the experience of living with cancer and comorbid illness in order to develop optimal models of patient-centred care. This protocol describes a systematic review that aims to identify the qualitative evidence relating to the experience of cancer and comorbid illness for patients, informal carers and professionals, and to highlight areas where more research is needed. Methods and analysis A systematic review following PRISMA guidance will be undertaken. Medline, Embase, CINAHL, PsycINFO, ASSIA, Sociological Abstracts, Web of Science, SCOPUS, OpenGrey and ProQuest Dissertations and Theses Global databases will be systematically searched for articles relevant to patient, carer and professional experiences. Two independent reviewers will screen articles for inclusion and evaluate them according to the Critical Appraisal Skills Programme tool. Extracted data will be combined using recognised methods of qualitative synthesis to offer new insights into the topic area and for a patient-centred model of care. Ethics and dissemination The review does not require formal ethical review as no direct patient contact or patient identifiable data is used. Conduct of the review has been approved internally by the University of Edinburgh Centre for Population Health Sciences Ethics Review Committee. Results of the review will be published in a generalist peerreviewed journal and presented at a relevant conference in addition to informing subsequent empirical work by the authors on this topic area

Is an opportunistic primary care-based intervention for non-responders to bowel screening feasible and acceptable?:A mixed-methods feasibility study in Scotland

Objectives We aimed to test whether a brief, opportunistic intervention in general practice was a feasible and acceptable way to engage with bowel screening non-responders. Design This was a feasibility study testing an intervention which comprised a brief conversation during routine consultation, provision of a patient leaflet and instructions to request a replacement faecal occult blood test kit. A mixed-methods approach to evaluation was adopted. Data were collected from proformas completed after each intervention, from the Bowel Screening Centre database and from questionnaires. Semi-structured interviews were carried out. We used descriptive statistics, content and framework analysis to determine intervention feasibility and acceptability. Participants Bowel screening non-responders (as defined by the Scottish Bowel Screening Centre) and primary care professionals working in five general practices in Lothian, Scotland. Primary and secondary outcome measures Several predefined feasibility parameters were assessed, including numbers of patients engaging in conversation, requesting a replacement kit and returning it, and willingness of primary care professionals to deliver the intervention. Results The intervention was offered to 258 patients in five general practices: 220 (87.0%) engaged with the intervention, 60 (23.3%) requested a new kit, 22 (8.5%) kits were completed and returned. Interviews and questionnaires suggest that the intervention was feasible, acceptable and consistent with an existing health prevention agenda. Reported challenges referred to work-related pressures, time constraints and practice priorities. Conclusions This intervention was acceptable and resulted in a modest increase in non-responders participating in bowel screening, although outlined challenges may affect sustained implementation. The strategy is also aligned with the increasing role of primary care in promoting bowel screening

Admixture and selection patterns across the European distribution of Scots pine, Pinus sylvestris (Pinaceae)

We analysed data on nucleotide polymorphism at 78 nuclear genes to search for signatures of divergence and selection in populations from across the distribution of Pinus sylvestris in Europe. Data on variation at a large set of maternally inherited mitochondrial DNA markers were also analysed. Most nuclear loci showed homogeneous patterns of variation across populations from Spain, Central Europe, Nordic countries and Scotland. Mitochondrial markers did not reveal strong population structure but suggested admixture of samples carrying different mitochondrial lineages in certain parts of the distribution. At nuclear DNA loci, we found high nucleotide polymorphism, generally low population differentiation and weak signals of isolation by distance. Together with the mitochondrial DNA results, these patterns seem most likely to be associated with a process of colonization from multiple sources and efficient gene flow. The results are in line with demographic inference indicating establishment of Central European and Nordic populations before the Last Glacial Maximum and admixture of colonization fronts from mainland Europe in Scottish populations. Coalescent and outlier detection methods identified several genes showing molecular signatures of selection especially in response to temperature variation in ecologically and phenotypically divergent populations. The study provides a large set of markers for analysis of genetic diversity in populations of P. sylvestris, including candidate genes that are implicated in local adaptation and population divergence

Effective management of ecological resilience – are we there yet?

1. Ecological resilience is developing into a credible paradigm for policy development and environmental management for preserving natural capital in a rapidly changing world. However, resilience emerges from complex interactions, limiting the translation of theory into practice. 2. Main limitations include the following: (i) difficulty in quantification and detection of changes in ecological resilience, (ii) a lack of empirical evidence to support preventative or proactive management and (iii) difficulties in managing processes operating across socio-ecological systems that vary in space and time. 3. We highlight recent research with the potential to address these limitations including new and/or improved indicators of resilience and tools to assess scale as a driver of resilience. 4. Synthesis and applications. Effective resilience-based management must be adaptive in nature. To support this, we propose an operational model using resilience-based iterative management actions operating across scales

Scotland’s biodiversity progress to 2020 Aichi Targets:Conserving genetic diversity- development of a national approach for addressing Aichi Biodiversity Target 13 that includes wild species

Aichi Target 13 (T13) focuses on the conservation of genetic diversity. •Major challenges in implementing T13 are that the type of genetic diversity to conserve is not clearly defined, and that key issues in genetic conservation vary across different sectors (e.g., forestry vs agriculture vs other species of socio-economic importance). •In Scotland and the UK more widely, baseline mechanisms are well established for assessing and reporting on genetic diversity in species of agricultural importance (e.g., rare livestock breeds, crop wild relatives), and a methodology has been established for ornamental plants. •A new UK Strategy for Forest Genetics Resources was launched in 2019, creating a framework for linking forest trees into T13 reporting. •However, there is no clear strategy to deal with ‘other species of socio-economic importance’ in Scotland, the UK or indeed elsewhere, and addressing this gap is the major focus of this report. •There is a lack of guidance for identifying focal species of socio-economic importance, and no clear mechanism for addressing T13 for these species once they have been identified. •To address this, we have identified a set of criteria for defining terrestrial and freshwater species of socio-economic importance in Scotland, and selected an initial list of 26 species. •The criteria applied were: -National conservation priority wild species. -Species of national cultural importance. -Species providing key ecosystem services. -Species of importance for wild harvesting (food and medicine). -Economically important game species. •We then developed a simple, readily applicable scorecard method for assessing risks to the conservation of genetic diversity in these species. •The scorecard approach is not dependent on prior genetic knowledge, and instead uses structured expert opinion assessments of whether: -Demographic declines are likely to lead to loss of genetic diversity (genetic erosion). -Hybridisation is likely to lead to undesirable replacement of genetic diversity. -Restrictions to regeneration/turnover are likely to impede evolutionary change. •For plant species where seed-banking is a viable mechanism for holding genetic resources ex situ,we also report on the representativeness of these ex situ collections. •Overall, this scorecard provides a mechanism for incorporating ‘other species of socio-economic importance’ into T13 actions and reporting. •Furthermore, its application is not restricted to Aichi T13 as the approach is designed as a generic scorecard for genetic diversity. It is thus relevant to post-2020 CBD targets focusing on genetic diversity. •Future priorities include: -Extension to other species of socio-economic, commercial and cultural importance (with the inclusion of marine species being a particularly high priority). -Harmonising genetic conservation strategies between sectors (drawing on commonalities), whilst minimising disruption of existing well-established methodologies within sectors. -Greater incorporation of genomic data into monitoring genetic diversity (particularly in the agricultural and forestry sectors where data availability is potentially high)
