Identifying metro station types based on transfer purposes: An application of bike-sharing data in Xiamen,China

With the networking of urban rail transit and the large-scale development of bike-sharing, metro and bike-sharing connection has become the preferred way of daily travel for residents of Xiamen. Current studies mainly identify metro station types based on node and place orientation, lacking behaviour-based investigation. To fill this gap, this study aims to explore the classification of metro stations based on transfer purposes by combining bike-sharing and point of interest data in Xiamen, using buffer analysis, kernel density estimation, and DBSCAN clustering algorithm comprehensively. The results indicate the following. (1) Distinct transfer purposes have significant agglomeration characteristics and present poly-centric spatial pattern, an authentic portrayal of Xiamen's land use function. (2) The heterogeneity of connection flow between different transfer purposes and metro stations is apparent. The distribution of flow and flow direction within the same transfer purpose is also in non-equilibrium. (3) Based on traffic connection analysis, metro stations are divided into seven types: transportation hub, employment-oriented, residence-oriented, job-housing balance, school-oriented, traffic-tourism integration, and business connection types. The obtained results assist in improving the transportation connection environment, perfecting urban land use planning, and enhancing low-carbon and green travel.     

When open data and data activism meet: An analysis of civic participation in Cape Town,South Africa

Municipal open data projects are motivated by a desire to democratize data access and knowledge production, strengthen transparency, and advance cities socially and economically. However, their effects and implications are insufficiently analyzed. This paper examines civic engagement in open data in Cape Town, South Africa, the continent's first municipal-level open data initiative. Findings reveal how local civil society organizations have been driving engagement with municipal open data as part of their recent turn towards technology and data-driven forms of public engagement and activism. This analysis highlights the important role of the “smart civil society organization”—occupying a position between the smart city and smart citizen—that is developing significant capacity to produce and share data about the city's informal settlements with stakeholders in government, the private sector, and wider society. Minimal engagement with or recognition of civil society efforts illustrates the limits to the city's philosophy of data openness, which is largely restricted to releasing selected government datasets to the public. The notion of “bi-directional open data” is developed here to characterize emerging possibilities for data openness between governments and the public. This may be particularly relevant for cities like Cape Town with a highly active, capable, and data-literate civil society.     

A theatre of machines: Automata circuses and digital bread in the smart city of Toronto

In this paper, the policies, projects, and promises of “smart” initiatives at the City of Toronto are evaluated, as they manifest through a technological convergence between local government services and an increased focus on citizen services through data-driven mediums. Through direct participant observation and formal interviews, a robust understanding of the internal institutional dynamics, the perspectives citizens in the “smart city,” and the operational disconnects in governance, policy, and practice has been gained. Our case study on the City of Toronto provides an account of how and from where these smart motivations for increasing a data-driven engagement with the public have arisen over the past several years. In doing so, we identify key characteristics that both enable and hinder the existing smart city in the forms of access to open data, the use of increased computational methods, and the engagement of public services through digital space as requirements for the future of participatory governance. We argue that instituting appropriate policies and engaging citizens to co-design and participate in the planning processes are essential to ensuring an inclusive, modern, and open smart city.     

Legacy databases and GIS: a discussion of the issues illustrated by a case study of archaeological site data from southeast Alberta,Canada

Many institutions and agencies are currently faced with the issue of geographic information systems‐enabling legacy databases. The problems can be acute for data sets that have been compiled through many years, using different standards and levels of recording. To explore these issues further, we report on a data quality assessment undertaken in 2002 for a subset of the archaeological site database of the province of Alberta, Canada. Our work shows that positional ambiguities in the data set can be highlighted and corrected by relatively straightforward procedures. This case study also provides an indication of the amount of work effort that will be involved in validating or ‘cleaning up’ data sets so model results and analyses undertaken with them are more reliable.     

Long-term trends in health status and determinants of health among the off-reserve Indigenous population in Canada, 1991–2012

The Indigenous population in Canada totals approximately 1.6 million individuals, representing about 5% of the total population. The off-reserve Indigenous population represents the fastest growing segment of the Indigenous population, with over 50% living in urban settings. Despite the size of the off-reserve population, research on the health of Indigenous peoples tends to remain focused on reserve-based populations. The purpose of this paper is to contribute to a better understanding of health and social determinants of health among off-reserve Indigenous peoples in Canada. Using data from the 1991 and 2012 Aboriginal Peoples Surveys this paper examines changes in health status and the social determinants of health over a 20-year time span. Results show a decline in health care use and self-reported health status in the period between 1991 and 2012. The results may be related to urbanization, aging, and increased prevalence of some chronic conditions. The findings may also be tied to barriers to achieving adequate off-reserve health care—jurisdictional disputes, disjointed program coverage, systemic racism, and a lack of equity-oriented health services. There remains a pressing need for Indigenous and non-Indigenous governments, researchers, and policymakers to build new relationships that bridge these gaps in health and access to timely care.     

Geographic accessibility to primary care providers: Comparing rural and urban areas in Southwestern Ontario

This research examines geographical accessibility to primary care providers (PCPs) across urban and rural areas of Southwestern Ontario and examines variations in the distribution of PCPs in relation to the senior population (aged 65 years and older). Information about PCP practices was provided by the HealthForceOntario Marketing and Recruitment Agency. Population data were obtained from the 2016 Census of Canada. To calculate scores for accessibility to PCPs (i.e., PCPs/10,000 population), we applied the enhanced 2-step floating catchment area method with distance decay effect within a global service catchment of 30-minute drive time. A geospatial mapping approach revealed disparities in the distribution of PCPs with a pattern of higher spatial accessibility in or around major urban areas in Southwestern Ontario. Comparative analyses were performed in association with the seniors’ population to identify how accessibility scores were mismatched with the population needs. The outcome of this study will assist researchers and health service planners to better understand the distribution of existing PCPs to address inequalities, particularly in rural areas.     

Indigenous student labour and settler colonialism at Brandon Residential School

This paper contends that unfree Indigenous student labour at residential schools was a key—and underappreciated—component of settler colonialism in Canada. Colonial administration and the churches attempted to “civilize” and assimilate Indigenous people—and prepare the frontier for white settlers—through residential schooling. Labour, in accordance with Euro-Canadian gender norms, was expected to usher Brandon Industrial Institute (later Brandon Residential School) students from the “backwardness” of traditional lifeways to the industriousness and assimilation necessary for their roles in the serving classes of modern society. I use archival sources—newspapers, unpublished reports, Department of Indian Affairs documents, and United Church correspondence and photographs—and employ a version of Norman et al.'s “settler-colonial grid of recognizability” to examine student labour. This paper argues that the Department of Indian Affairs and church officials at Brandon Residential School sought to make Indigenous youth “legible” under the settler-colonial grid of recognizability through agricultural and manual work for boys and domestic labour for girls, both of which ensured the school's financial viability. I propose that this under-explored aspect of settler colonialism could be understood through three main themes—imperial settler-humanitarianism, the logic of containment, and productive bodies—that are traced across the lifetime of the school.     

Scenarios of climate change and natural resource development: Complexity and uncertainty in the Nechako Watershed

Climate change and resource development interact to have significant impacts on both natural and human systems within watersheds. It is, however, difficult to conceptualize and communicate these intersections, as climate change and resource development are each independently uncertain and complex. We facilitated a process whereby stakeholders created plausible future scenarios for the Nechako Watershed in British Columbia, Canada. This region is reliant upon, and has been significantly affected by, many types of resource exploitation. During a full-day workshop, 32 stakeholders created scenarios for 2050 envisioning high and low levels of both resource development and climate change. The high and low levels of climate change were based on downscaled projections from global emissions scenarios, and the resource development levels were determined at the beginning of the workshop by the participants. The exercise was educational, and motivated stakeholders to conceptualize plausible future changes and their impacts, and the outcomes should motivate stakeholders to work towards realizing a more desired future. All scenarios (even low-low) were deemed to have significant negative impacts, suggesting that the Nechako Watershed is in a vulnerable state. The complexity of the exercise suggests that more capacity building may be necessary.     

Trends in the residential mobility of seniors in Canada, 1961–2006

This article examines residential mobility for seniors 65 years of age and older in Canada using census data from 1961–2006. We addressed three questions. First, have seniors been increasingly likely to change their residential location within Canada or alternatively become increasingly likely to age‐in‐place? Second, has the in‐migration of seniors to Canada from other countries become more pronounced over the years? Third, does the residential mobility of seniors vary by age and sex? We used census data to calculate the percentages of seniors who changed their residence in the five‐year periods prior to each of the 1961–2006 censuses and the percentages of seniors who moved in the previous year for the 1991–2006 censuses. We calculated the percentages of seniors making local moves, longer distance moves within the same province, moves from one province to another, and moves to Canada from another country. We found that rates of residential mobility for seniors tended to increase in the 1961–1981 period but have been lower and relatively consistent from 1986–2006. We found no evidence to suggest a pattern of sustained increase in residential mobility of seniors. We conclude that Canadian seniors tend to age‐in‐place and that when seniors do change residence, the likelihood of residential mobility decreases with the distance of the move and decreases with age. Nevertheless, the likelihood of changing residence may increase for seniors 75+ years of age who need assistance and are at risk of institutionalization. We found that senior women were more likely to change residence locally than senior men. Finally, we found that from 1961 to 2006 between 0.8 percent and 1.4 percent of seniors had migrated to Canada in the five years prior to each census from other countries and that this pattern has fluctuated over the past half century with no clear trend.     

Residential segregation and inequality: Considering barriers to choice in Toronto

Segregation of visible minorities has persisted throughout time in Toronto. In examining these concentrations, the literature has been heavily focused on the notion that visible minorities are choosing to live in proximity to their respective ethno-racial groups and that these are spaces of aspiration rather than marginalization in Canada. This paper raises questions about the assertion of “self-segregation” by emphasizing affordability constraints on residential choices that are often rooted in discrimination in the labour market. Census data from 2016 and an adopted neighbourhood classification scheme were used to understand the spatial patterning of visible minorities in the Toronto census metropolitan area and highlight differences in the socio-economic characteristics of visible minority dominant and white dominant census tracts. The findings invite the inference that economic opportunities play a critical role in the residential choices of visible minorities and raise concerns about the quality of life in visible minority neighbourhoods. This research contributes to our understanding of how social inequalities have impacted the socio-spatial organization of the city of Toronto.     

Intellectual property and the licensing of Canadian government geospatial data: an examination of GeoConnections' recommendations for best practices and template licences

In Canada, Crown copyright permits government to assert control over its works. These Crown rights have often been justified on the basis that government must assert intellectual property rights so as to be better able to control the accuracy, integrity and quality of any information that reaches the public through Crown works. In this article, the authors examine GeoConnections' template agreements for the licensing of government geographic data. They argue that not only is the basis and scope of claims to intellectual property rights uncertain, the objectives of quality control, data integrity and accuracy do not appear to motivate the licence terms. The uncertainty as to the legal basis of the intellectual property claims is significant, as licences of this kind may give support to otherwise weak downstream claims by third parties to copyright in data products generated through the use of geographic data provided by the Crown.     

Searching for Nineteenth-Century Farm Tenants: An Evaluation of Methods

Abstract

In tandem with a recent surge in interest in lynching in the United States in the late 19th and early 20th centuries, researchers in a number of fields have begun to use lynching data in new ways for a wide range of empirical investigations. A limited number of historical national lynching data series are available, have well-known flaws, and are nonetheless used. This article analyzes and compares these series, summarizes recent efforts to address their shortcomings, and identifies extensions that could aid in the construction a national database of confirmed lynching victims, whose broader applications are just beginning to be explored.     

“Why would they care?”: Youth,resource extraction,and climate change in northern British Columbia,Canada

Discussion about local decision making tends to overlook rural and remote youth engagement. Resource extractive industries are, however, fixtures in many rural, remote, northern, and Indigenous communities in settler colonial British Columbia, Canada. These industries shape youths' perceived options for social and economic ventures when they are looking towards their futures. By engaging literature on climate change, settler colonialism, and critical Indigenous studies, and drawing on empirics from workshops conducted with youth from northern British Columbia, this paper explores how rural and remote northern and Indigenous youth engagement and perspectives can transform discussions on climate change and resource extraction. The paper documents how rural and northern youth have been engaged in environmental decision making, particularly in light of resource extraction. The paper also suggests that environmental decision making has at times been extractive itself. The paper concludes that when engaged meaningfully, youth desire to work collectively against social and environmental injustices.     

An Archaeomagnetic Study of a Roman Bath in Southern France

Absolute Thellier–Thellier archaeointensity determinations were conducted on 137 tiles and sedimentary blocks from five different structures from the ‘Site de la Molère’, southern France, to constrain the archaeological interpretation of a relative age difference between structures and add new data to the French secular variation database. We present 89 new archaeointensity and 20 new directional results, with averages of 57 (±8) μT in the second century ad and 68 (±7) μT in the third century ad . The overall data trend is consistent with the limited available data, indicating rapidly increasing field intensity from the second to the third century ad .     

A framework for path-dependent industrial land transition analysis using vector data

Industrial land is under transition globally. Insights into this transition are important to plan a sustainable future. Since industrial land follows parcel shapes and the transition process requires multi-year data to observe the impacts of such changes, multi-year vector data should be used to analyse industrial land transition. This paper presents a framework to analyse path-dependent regional industrial land transition processes using vector data. A step by step instruction is presented. In the analysis, the changed percentages of land use in the surroundings of appeared or disappeared industrial land are visualized. The visualized surrounding land use compositions give planners an idea on what causes land use transitions, the most frequent transition forms and their impacts on the surroundings, purely from a land use point of view to reduce data collection efforts. The North Brabant region in the Netherlands is used as a case study. The region is split into urban and non-urban areas to show the generic applicability of this framework.     

The geographies of crisis: exploring accessibility to health care in Canada

There is increasing concern in Canada that the health care system is in a state of crisis. It is argued that reductions in federal government transfers to the provinces have resulted in a health care system characterized by under‐funding in key areas and policy decisions based more on provincial fiscal concerns than the health needs of their constituents. Provincial governments have responded to reduced levels in federal funding by undertaking aggressive restructuring tactics such as the closure of hospitals and the deinsuring of medical services from provincial health plans. The end result of this restructuring, as argued by the media, consumer groups and indeed some health researchers, is a state of crisis' (i.e., lower levels of accessibility, long waiting lists, overcrowding in hospitals and increasing costs of medication). One crisis theme often mentioned is that fiscal decisions of various kinds are reducing economic and geographic accessibility, one of the five principles of the Canada Health Act (CHA) that defines the very essence of the Canadian health care system. Using data from the 1998‐99 National Population Health Survey (NPHS), this paper explores the extent to which an accessibility crisis exists within the Canadian health care system by examining access to health care services and the barriers encountered in trying to access services in each of the ten provinces. The results show that approximately 6.0 percent of Canadians report access problems, with values ranging from 4.5 percent in Newfoundland to 8.3 percent in Manitoba. Regional variations in barriers to accessing care were also observed. In particular, geographic accessibility appears to be a main barrier to care in Atlantic Canada while economic accessibility emerges as a main barrier to care in Western Canada. We discuss these findings in the context of the current debates on the Canadian health care system ‘crisis’. De plus en plus de Canadiens s'inquiétent que leur systéme de soins de santé soit en état de crise. On défend l'idée selon laquelle la réduction des paiements de transfert aux provinces par le gouvernement fédéral serait responsable de l'état d'un systeme de santé caractérisé par un sous‐financement dans les domaines‐clés et des décisions politiques de santé basées, non pas sur les besoins des membres de la société canadienne, mais sur la fiscalité provinciale. Les gouvernements provinciaux ont réagi à la réduction du financement fédéral par une tactique de restructuration agressive (fermeture d'hôpitaux et retrait de services médicaux des programmes d'assurance de santé provinciaux). Selon les médias, les groupes de consommateurs et même les chercheurs en soins de santé, cette restructuration a eu pour effet un système en état de ‘crise’ (diminution de l'aecès aux services, longues fetes d'attente, hôpitaux surchargés, augmentation des coûts des médicaments etc). Un des thèmes récurrent est celui des décisions flscales de toutes sortes qui entraînent une baisse de l'accessibilité financière et géographique. Cette accessibilité est pourtant un des cinq principes de la Loi canadienne sur la santé définissant l'essence même du système de santé au Canada. Utilisant les données tirèes de l'Enquête nationale sur la santé de la population, 1998‐99 et examinant l'accès aux services de santé et les obstacles rencontrés dans les 10 provinces canadiennes, cet article évalue dans quelle mesure une crise d'accessibilité existe au sein du système de santé canadien. Les résultats démontrent qu'environ 6.0 pour cent des Canadiens ont rencontré des problèmes d'accessibilité, avec des variantes allant de 4.5 pour cent à Terre‐Neuve jusqu'à 8.3 pour cent au Manitoba. On observe aussi des variantes régionales dans les obstacles rencontrés. L'accessibilité géographique en particulier semble un obstacle mqjeur dans les régions de l'Atlantique, alors que l'accessibilite financière semble être un obstacle majeur dans l'Ouest du Canada. Ces résultats sont présentés dans le contexte des débats actuels sur l'existence dune, ‘crise’ dans le système de santé au Canada.     

FUZZY PATTERN CLASSIFICATION OF STRONG GROUND MOTION RECORDS

Classification of earthquake strong ground motion (SGM) records is performed using fuzzy pattern recognition to exploit knowledge in the data that is utilised in a genetic algorithm (GA) search and scaling program. SGM records are historically treated as “fingerprints” of certain event magnitude and mechanism of faulting systems recorded at different distances on different soil types. Therefore, databases of SGM records of today present data of complex nature in high dimensions (many of the dimensions—or SGM parameters in time and frequency domain—are presently available from different archives). In this study, simple ground motion parameters were used but were combined and scaled nonlinearly such that the physical properties of the data could be preserved while reducing its dimensionality. The processed data was then analysed using fuzzy c-means (FCM) clustering method to explore the possibility of meaningfully representing earthquake SGM data in lower dimensions through finding subsets of mathematically similar vectors in a benchmark database. This representation can be used in practical applications and has a direct influence on the processes of synthesising ground motion records, identifying unknown ground motion parameters (e.g. soil type in this study), improving the quality of matching SGM records to design target spectra, and in rule generalisation for response. The results showed that the stochastic behaviour of earthquake ground motion records can be accurately simplified by having only a few of motion parameters. The very same parameters may also be utilised to derive unknown characteristics of the motion when the classification task on “training” records is performed carefully. The clusters are valid and stable in time and frequency domain and are meaningful even with respect to seismological features that were not included in the classification task.     

Shooting in the Dark: Recovering the Jewish Farmers of an American Zion

Abstract

The authors argue that the publication of any new historical data series requires a formal estimate of its margins of error. We show how overall margins of error may be calculated for the standard forms of historical data series from information on the reliability of its components. The presentation of such margins of error should be transparent, allowing readers both to judge the estimate and to test the implications of applying different standards. An illustration is provided for Hoffmann's industrial output series for Britain, 1780–1831. The calculations emphasize the value of this approach to the recent debate on measuring growth rates during the British Industrial Revolution and suggest its merits more generally.     

Creating a Historical International Standard Classification of Occupations An Exercise in Multinational Interdisciplinary Cooperation

This major international history project succeeded because of the goodwill, commitment, and collaborative endeavor of a team of researchers drawn not only from different countries but also from different disciplines. Its immediate product is a recently published book, HISCO: Historical International Standard Classification of Occupations (van Leeuwen, Maas, and Miles 2002). The authors describe the substantive issues, methodological questions, and practical arrangements behind the HISCO scheme, which is a classification tool designed to enable researchers working with historical occupational titles in a variety of linguistic and geographical contexts to communicate with each other and to make international comparisons across the nineteenth and twentieth centuries in social, economic, and other fields of history. HISCO is rooted in the 1968 version of the International Labour Organisation [then known as Office]'s International Standard Classification of Occupations (ISCO68) (ILO 1969). This means that in addition to comparing historical information across national boundaries, we can establish linkages between historical and contemporary data sets. The authors also note some recent developments on the application of HISCO in historical research.     

Beyond perception: Spatial analysis of detached ADU potential on residential lots in Windsor,Ontario

This paper analyzes the spatial potential of detached additional dwelling units (ADUs) in Windsor, Ontario. A new GIS model, which integrates various geoprocessing commands in ArcGIS 10.8.1, is developed to calculate whether the minimum allowable size of a detached ADU can fit within the total buildable area of a residential property, based on the setbacks, the lot coverage requirements, and other factors (such as parking and flood plain areas). The model uses publicly sourced data that were obtained from the City of Windsor's Open Data Portal. More specifically, individual residential parcels and associated building footprints along with street centerlines are used as inputs to the model. The outputs are then categorized into three types (suitable, potentially suitable, and not suitable) to demonstrate where detached ADUs can be built in compliance with the local zoning bylaws, on both an individual lot basis and at an aggregate level. The conducted analysis reveals the potential of existing residential neighbourhoods in a mid-size city, and has many implications for homeowners, policymakers, and researchers with respect to increasing housing supply within current Canadian municipalities.
