AbstractHourly measurements of particulate matter that is smaller than 2.5 μm in diameter (PM2.5) have been made at air-monitoring sites in Hamilton and Burlington, Ontario, Canada, since 2003. These sites are separated by ~6 km; Burlington is right on Lake Ontario while Hamilton has, directly to the east, very heavy industry between it and Lake Ontario. Hence, by taking the difference between measurements at Hamilton and Burlington, it is possible to isolate, during east-wind conditions, PM2.5 that result from emissions from the industrial sectors (primarily steel mills) located in Hamilton’s northeast end. After screening the data for east winds off Lake Ontario, it was found that median background values of PM2.5, of 5–10 μg m−3 are increased by an additional 5–10 μg m−3 by emissions from local sources. On the contrary, however, industrial contributions to PM2.5 in Burlington during south winds are much smaller at ~3 μg m−3 (industrial sectors are due south of Burlington). This difference is likely due either to wind direction–dependent local circulation patterns or to alignment of sources that can concentrate PM2.5 into Hamilton. It was also found that throughout much of 2009, but especially during spring and early summer, the industrial contribution of PM2.5 at Hamilton was reduced relative to other years by amounts that are statistically significant at the 95% confidence level, even when measurements are augmented with large amounts of Gaussian noise. These reductions are consistent with documented reductions in steel production during the global economic crisis that peaked in the first half of 2009.

Abstract Hamilton Harbour is an enclosed body of water situated at the western end of Lake Ontario and containing about 2.8 x 108 m3 of water, polluted by municipal and industrial effluents. It is connected to Lake Ontario by a ship canal, which facilitates a substantial exchange of water between the two water bodies. Exchange of harbour and lake water through the canal reduces the theoretical hydraulic residence time of the harbour and contributes to improvement of the harbour water quality through dilution and oxygenation. Without it, the Hamilton Harbour water quality situation would be more critical. The beneficial effect of dilution by Lake Ontario far exceeds contamination of western Lake Ontario by Hamilton Harbour water.

This article argues that the creative drive of cultural workers to envision alternative urban futures and to make real changes in neighbourhoods in the urban present, while politically powerful and imaginatively seductive to urban decision-makers, contains destructive impulses. Such a drive can challenge, but also reinforce, the established social order and unequal power relations. This article critically examines the spatial politics of creative destruction that can unfold in the place-making wake of cultural workers. A case study is used from the mid-sized, industrial city of Hamilton of a deprived inner-city neighbourhood that is informally being reimagined as an arts district. In this neighbourhood, some cultural workers selectively practice middle-class disaffiliation. Individual acts of avoidance, control and destruction function as withdrawal strategies to help minimise the negative externalities of crime and social disorder and to realise a vision of this neighbourhood in their own image.

Abstract Large-volume water samples were collected from the ship canal connecting Hamilton Harbour and Lake Ontario while detailed simultaneous measurements of water speed and direction were made. The 10-day sampling period in July 1989 and a 14-day sampling period in March 1991 were considered representative of typical stratified summer and unstratified winter flow regimes. The water samples were analysed for PCBs and PAHs, which are known major organic contaminants in Hamilton Harbour. Supporting physicochemical measurements were also made. The water movement data were combined with the contaminant concentrations and the uniform channel dimensions to calculate annual loadings of 2.8 kg/ year PCBs and 37.5 kg/ year PAHs from Hamilton Harbour to Lake Ontario. These estimates were compared to other published estimates of loadings of these compounds from Hamilton Harbour and also from the atmosphere and the Niagara River. It was concluded that Hamilton Harbour is not a significant source of these compounds in comparison to the atmosphere and the Niagara River. The PAH export estimate was found to be small when compared to in situ sediment burdens of PAHs and also present day discharges to the harbour.

Abstract The temporal and spatial distribution of total and toxic unionized ammonia, nitrite, nitrate and total dissolved nitrogen concentrations in Hamilton Harbour, Lake Ontario, were investigated during 1987–1988. The concentrations of toxic un-ionized ammonia in vertical and horizontal profiles depended on ammonia loadings from the Hamilton and Burlington municipal sewage treatment plants, the seasonal nitrogen cycle, pH and water temperature. Toxic ammonia levels in the Harbour exceeded the International Joint Commission objective of 20 μg/L at all sampling sites for about half of the year (spring and summer). For extended periods in the late spring and mid-summer, concentrations frequently exceeded the chronic toxicity threshold of 300 μg/L. Toxic un-ionized ammonia concentrations were distributed unevenly over the Harbour with a distinct areal zonation and patchiness. Volatilization of ammonia, estimated at 6.8 tonnes per summer, reduced the toxic effect but was insignificant in the overall NH3-N budget. The nitrite concentrations exceeded the chronic toxicity thresholds of 30 μg/L for most of the summer and frequently surpassed the cold-water fish toxic levels of 250 μg/L. Near the outfall from the Hamilton sewage treatment plant, nitrite levels were 600–1,200 μg/L. The frequency of nitrite toxic episodes was however lower than those of un-ionized ammonia. Nitrite was less abundant than total ammonia and can be considered as a less serious contaminant. Nitrification in Hamilton Harbour appeared to be inhibited by high toxic un-ionized ammonia levels.

Abstract The concentrations and relative abundances of sixteen priority pollutant polycyclic aromatic hydrocarbons (PAHs) were measured in suspended particulates and benthic sediments from Hamilton Harbour. The PAH concentrations in suspended particulates, often as high as PAH concentrations in benthic sediments, ranged between 4.41 and 106.02 µg/g. The highest PAH concentrations were found in areas close to the industrial sites. Selected samples of suspended particulates from western part of Lake Ontario were also analyzed for PAHs to learn about the transport of PAHs from the harbour to Lake Ontario via the Burlington Ship Canal. The results reveal export of PAHs along with the other contaminants from Hamilton Harbour to Lake Ontario. In addition to PAHs, n-alkanes were determined in all samples, as they are readily determined from the extracts and they are useful in deciphering the sources of suspended particulates, hence particle-associated PAHs.

A new specimen of the locally rare ammonoid Agoniatites has been recovered from the Middle Devonian Hamilton Group at Hungry Hollow, southwestern Ontario. Although immature, the specimen displays close affinity to Agoniatites vanuxemi Hall, with which it may be conspecific. An earlier and long-since discredited record of Agoniatites from Ontario is therefore reconfirmed. Despite continued uncertainty as to its precise stratigraphic provenance, the Ontario Agoniatites may prove important for regional correlation.

Sediments from Hamilton Harbour and an uncontaminated control site were collected and extracted for organic contaminants to investigate the putative association between chemical contaminants and high incidences of fish tumours in Hamilton Harbour. Sediment extract from Hamilton Harbour had high levels of polynuclear aromatic hydrocarbons and was mutagenic in the Ames bacterial mutagenicity assay. In two sets of experiments using a trout sac-fry microinjection route of exposure, Hamilton Harbour sediment extract induced hepatocellular carcinomas in rainbow trout (Salmo gairdneri).

In the face of changing economies and patterns of development, the definition of heritage is diversifying, and the role of inventories in local heritage planning is coming to the fore. The Durand neighbourhood is a layered and complex area located in inner-city Hamilton, Ontario, Canada, and the second subject area in a set of pilot inventory studies to develop a new city-wide inventory strategy for the City of Hamilton,. This paper presents an innovative digital workflow developed to undertake the Durand Built Heritage Inventory project. An online database was developed to be at the centre of all processes, including digital documentation, record management, analysis and variable outputs. Digital tools were employed for survey work in the field and analytical work in the office, resulting in a GIS-based dataset that can be integrated into Hamilton’s larger municipal planning system. Together with digital mapping and digitized historical resources, the Durand database has been leveraged to produce both digital and static outputs to shape recommendations for the protection of Hamilton’s heritage resources.

Single adult females remain among the most vulnerable of all refugee populations. However, there is a lack of research on supporting and empowering these women. There is a new interest in identifying factors that reinforce resilience and, ultimately, adjustment to the host country. In line with the current work on resilience, semi-structured, indepth, personal interviews with single refugee women were conducted in the city of Hamilton, Ontario. A grounded theory approach revealed participants’ perspectives on the support received from religious or cultural communities, non-governmental organizations, and the government in terms of their perceived contribution to adaptation. Both informal and formal support, along with individual characteristics, were found to be crucial for reinforcing resilience among these refugees, reflective of a collective resilience model that moves beyond individual and community resilience. Future research should aim to investigate the perspectives of those who did not receive social support from shelters as well as to assess the efficacy of current refugee support services.

To study the origins of airborne particulate organic matter in southern Ontario, molecular marker concentrations were studied at Hamilton, Simcoe, and York Gateway Tunnel, representing industrial, rural, and heavy traffic sites, respectively. Airborne particulate matter smaller than 10 μm in aerodynamic diameter was collected on quartz filters, and the collected samples were analyzed for total carbons, 5-6 ring PAHs, hopanes, n-alkanes (C20 to C34), and oxygenated aromatic compounds. Results showed that PAH concentrations at all three sites were highly correlated, indicating vehicular emissions as the major source. Meanwhile, in the scatter plots of α,β-hopane and trisnorhopane, concentrations displayed different trends for Hamilton and Simcoe. The slopes of the linear regressions for Hamilton and the tunnel were statistically the same, while the slope for Simcoe was significantly different from those. Comparison with literature values revealed that the trend observed at Simcoe was explained by the influence from coal combustion. We also found that the majority of oxygenated aromatic compounds at both sites were in the similar level, possibly implying secondary products contained in the southern Ontario air. Regardless of some discrepancies, absolute principal component analysis applied to the datasets could reproduce those findings.

The medical school at McMaster University (Hamilton, Ontario) was conceived in 1965 and admitted the first class in 1969. John Evans became the founding Dean and he invited Moran Campbell to be the first Chairman of the Department of Medicine. Moran Campbell, already a world figure in respiratory medicine and physiology, arrived at McMaster in September 1968, and he invited Norman Jones to be Coordinator of the Respiratory Programme.At that time, Hamilton had a population of 300,000, with two full-time respirologists, Robert Cornett at the Hamilton General Hospital and Michael Newhouse at St Joseph’s Hospital. From the clinical perspective, the aim of the Respiratory Programme was to develop a network approach to clinical problems among the five hospitals in the Hamilton region, with St Joseph’s Hospital serving as a regional referral centre, and each hospital developing its own focus: intensive care and burns units at the Hamilton General Hospital; cancer at the Henderson (later Juravinski) Hospital; tuberculosis and rehabilitation at the Chedoke Hospital; pediatrics and neonatal intensive care at the McMaster University Medical Centre; and community care at the Joseph Brant Hospital in Burlington (Ontario). The network provided an ideal base for a specialty residency program. There was also the need to establish viable research.These objectives were achieved through collaboration, support of hospital administration, and recruitment of clinicians and faculty, mainly from our own trainees and research fellows. By the mid-1970s the respiratory group numbered more than 25; outpatient clinic visits and research had grown beyond our initial expectations. The international impact of the group became reflected in the clinical and basic research endeavours.ASTHMA: Freddy Hargreave and Jerry Dolovich established methods to measure airway responsiveness to histamine and methacholine. Allergen inhalation was shown to increase airway responsiveness for several weeks, and the late response was shown to be an immunoglobulin E-mediated phenomenon. Paul O’Byrne and Gail Gauvreau showed that the prolonged allergen-induced responses were due to eosinophilic and basophilic airway inflammation and, with Judah Denburg, revealed upregulation of eosinophil/basophil progenitor production in bone marrow and airways. The Firestone Institute became the centre of studies identifying the inflammatory pheno-type of patients with difficult-to-control asthma. Freddy Hargreave and others developed methods for sputum induction to identify persisting eosinophilic airway inflammation and documented its presence in the absence of asthma and in patients with persistent cough. Parameswaran Nair has applied these techniques to the management of asthma in routine clinical practice. The Asthma Quality of Life Questionnaire and the Asthma Control Tests were developed by Drs Liz Juniper and Gordon Guyatt. The first Canadian evidence-based clinical guidelines for asthma management in 1989 were coordinated by Freddy Hargreave, Jerry Dolovich and Michael Newhouse.DISTRIBUTION OF INHALED PARTICLES: Michael Newhouse and Myrna Dolovich used inhaled radiolabelled aerosols to study the distribution of inhaled particles and their clearance in normal subjects, smokers and patients with chronic obstructive pulmonary disease. They developed the aerochamber, and were the first to radiolabel therapeutic aerosols to distinguish the effects of peripheral versus central deposition. Particle deposition and clearance were shown to be impaired in ciliary dyskinesia and cystic fibrosis.DYSPNEA: Moran Campbell and Kieran Killian measured psychophysical estimates of the sense of effort in breathing in studies of loaded breathing and exercise to show that dyspnea increased as a power function of both duration and intensity of respiratory muscle contraction, and in relation to reductions in respiratory muscle strength. These principles also applied to dyspnea in cardiorespiratory disorders.EXERCISE CAPACITY: Norman Jones and Moran Campbell developed a system for noninvasive cardiopulmonary exercise testing using an incremental exercise test, and more complex studies with measurement of mixed venousPCO2by rebreathing. The 6 min walk test was validated by Gordon Guyatt. Kieran Killian and Norman Jones introduced routine muscle strength measurements in clinical testing and symptom assessment in exercise testing. Muscle strength training improved exercise capacity in older subjects and patients with chronic obstructive pulmonary disease.METABOLISM AND ACID-BASE CONTROL IN EXERCISE: After showing that imposed acidosis reduced, and alkalosis improved performance, Norman Jones, John Sutton and George Heigenhauser investigated the interactions between acid-base status and metabolism in exercise.HIGH-ALTITUDE MEDICINE: John Sutton and Peter Powles participated in high-altitude research on Mount Logan (Yukon), demonstrating sleep hypoxemia in acute mountain sickness and its reversal by acetazol-amide, and participated in Operation Everest II.EPIDEMIOLOGY: David Pengelly and Tony Kerrigan followed children living in areas with differing air quality to show that lung development was adversely affected by pollution and maternal smoking. Malcolm Sears and Neil Johnstone showed that the ‘return to school’ asthma exacerbation epidemic was due mainly to rhinoviruses. David Muir investigated the effects of silica exposure in hard-rock miners, and mortality in the nickel industry.SUMMARY: The Respirology Division has grown to more than 50 physicians and PhD scientists, and currently provides the busiest outpatient clinic in Hamilton, and has successful training and research programs.

AbstractObjectiveEvaluate the incidence, neurologic morbidity, and mortality of patients with Terson syndrome.MethodsConsecutive patients admitted to the Hamilton General Hospital from May 2012 to May 2013 with a diagnosis of spontaneous subarachnoid hemorrhage (SAH) were recruited. Funduscopic examinations were performed under pharmacological mydriasis. Outcome measures included: (1) the presence or absence of Terson syndrome; (2) The Glasgow Coma Scale (GCS), Hunt and Hess scale (H&H), and SAH Fisher score upon admission to the hospital; (3) the modified Rankin score upon discharge; and (4) and all-cause mortality.ResultsForty-six patients were included and 10 had Terson syndrome (21%). The median H&H, GCS, and Fisher scores were 4, 6.5, and 4.0 for patients with Terson syndrome vs. 2, 14, and 3 for patients without Terson syndrome (p=0.0032, 0.0052, and 0.031), respectively. The median Rankin score was 6 for patients with Terson syndrome vs. 3.5 for patients without Terson syndrome (p=0.0019). The odds of all-cause mortality with Terson syndrome vs. no Terson syndrome was 12: 1 (95% confidence interval 2.33-61.7), p =0.003. Only four of the 10 patients with Terson syndrome survived.ConclusionsBased on this study, approximately one-fifth of patients admitted to the hospital with a spontaneous SAH could have Terson syndrome. Patients with Terson syndrome have significantly worse GCS and H&H scores upon admission to the hospital, lower modified Rankin scores upon discharge, and greater mortality. Thus, Terson syndrome is not rare among patients with SAH and carries a worse prognosis.

There was also the need to establish viable research.These objectives were achieved through collaboration, support of hospital administration, and recruitment of clinicians and faculty, mainly from our own trainees and research fellows. By the mid-1970s, the respiratory group numbered more than 25; outpatient clinic visits and research had grown beyond our initial expectations. The international impact of the group became reflected in the clinical and basic research endeavours.ASTHMA: Freddy Hargreave and Jerry Dolovich established methods to measure airway responsiveness to histamine and methacholine. Allergen inhalation was shown to increase airway responsiveness for several weeks, and the late response was shown to be an immunoglobulin E-mediated phenomenon. Paul O’Byrne and Gail Gauvreau showed that the prolonged allergen-induced responses were due to eosinophilic and basophilic airway inflammation and, with Judah Denburg, revealed upregulation of eosinophil/basophil progenitor production in bone marrow and airways. The Firestone Institute became the centre of studies identifying the inflammatory phenotype of patients with difficult-to-control asthma. Freddy Hargreave and others developed methods for sputum induction to identify persisting eosinophilic airway inflammation and documented its presence in the absence of asthma, and in patients with persistent cough. Parameswaran Nair has applied these techniques to the management of asthma in routine clinical practice. The Asthma Quality of Life Questionnaire and the Asthma Control Tests were developed by Liz Juniper and Gordon Guyatt. The first Canadian evidence-based clinical guidelines for asthma management in 1989 were coordinated by Freddy Hargreave, Jerry Dolovich and Michael Newhouse.DISTRIBUTION OF INHALED PARTICLES: Michael Newhouse and Myrna Dolovich used inhaled radiolabelled aerosols to study the distribution of inhaled particles and their clearance in normal subjects, smokers and patients with chronic obstructive pulmonary disease. They developed the aerochamber, and were the first to radiolabel therapeutic aerosols to distinguish the effects of peripheral versus central deposition. Particle deposition and clearance were shown to be impaired in ciliary dyskinesia and cystic fibrosis.DYSPNEA: Moran Campbell and Kieran Killian measured psychophysical estimates of the sense of effort in breathing in studies of loaded breathing and exercise to show that dyspnea increased as a power function of both duration and intensity of respiratory muscle contraction, and in relation to reductions in respiratory muscle strength. These principles also applied to dyspnea in cardiorespiratory disorders.EXERCISE CAPACITY: Norman Jones and Moran Campbell developed a system for noninvasive cardiopulmonary exercise testing using an incremental exercise test, and more complex studies with measurement of mixed venousPCO2by rebreathing. The 6 min walk test was validated by Gordon Guyatt. Kieran Killian and Norman Jones introduced routine muscle strength measurements in clinical testing and symptom assessment in exercise testing. Muscle strength training improved exercise capacity in older subjects and patients with chronic obstructive pulmonary disease.METABOLISM AND ACID-BASE CONTROL IN EXERCISE: After showing that imposed acidosis reduced, and alkalosis improved performance, Norman Jones, John Sutton and George Heigenhauser investigated the interactions between acid-base status and metabolism in exercise.HIGH-ALTITUDE MEDICINE: John Sutton and Peter Powles participated in high-altitude research on Mount Logan (Yukon), demonstrating sleep hypoxemia in acute mountain sickness and its reversal by acetazolamide, and participated in Operation Everest II.EPIDEMIOLOGY: David Pengelly and Tony Kerrigan followed children living in areas with differing air quality to show that lung development was adversely affected by pollution and maternal smoking. Malcolm Sears and Neil Johnstone showed that the ‘return to school’ asthma exacerbation epidemic was due mainly to rhinoviruses. David Muir investigated the effects of silica exposure in hard-rock miners, and mortality in the nickel industry.SUMMARY: The Respirology Division has grown to more than 50 physicians and PhD scientists, currently provides the busiest outpatient clinic in Hamilton, and has successful training and research programs.

The promotion of active transportation (AT), which has been broadly defined as a physical effort performed by the traveller to produce motion, has been a popular strategy to reduce vehicular emissions, improve air quality, and promote physical activity. However, individuals who engage in AT may incur increased exposure to air pollutants and thus potential health impacts. This research sought to determine how active commuters understand the health risks associated with air pollution during their commutes, and whether they engage in any behaviours to limit exposure. An online survey was adapted from the Environmental Health Literacy framework to assess air pollution health literacy among active commuters in Hamilton, ON, and generated a sample size of 192 AT users. Analyses involved the use of frequency tables and cross-tabulations for the quantitative data, and the Health Belief Model and thematic analysis to interpret the qualitative data. Results revealed that most AT users do not adopt behaviours that would limit air pollution exposure on commutes and exhibited low self-rated knowledge of the health impacts of air pollution exposure. Issues of perceived susceptibility and severity, barriers, cues to action, and self-efficacy all further impacted the likelihood of adopting health protective behaviours. Conclusively, air pollution is an often-neglected consideration among active commuters, with air pollution knowledge predicting the likelihood of behavioural modification.

Abstract Bioassay procedure was used to measure dissolved organic carbon (DOC) and biodegradable dissolved organic carbon (BDOC) in Hamilton Harbour and western Lake Ontario using batch experiments with an incubation time of 12 days in four experiments. Three different levels of natural DOC concentration were assayed; high concentration of DOC, 20.2 mg C/1 (influence of sewage treatment inflow); intermediate concentration of DOC, 16.7 mg C/1 (STELCO plant, industry polluted water); and an unaffected locality with low concentration of DOC, 12 mg C/1 (predominantly autochtonous input from photosynthetic activity in Lake Ontario). Decreasing DOC in all samples was observed during the first five days of experiments followed by a stabilization of DOC at a constant level. The value of the labile fraction of DOC represented 75% of total amount of DOC in the sewage sample water, 57% in the sample affected by industrial waters and 66% of DOC in unaffected sample from Lake Ontario. Bacterial growth started rapidly from the first day of batch experiments and maximal biomass was reached after two to three days. The highest bacterial biomasses were reached in the samples affected by sewage treatment waters (2.37 mg C/1) and the lowest value was observed in Lake Ontario (0.51 mg C/1).

The term “gateway” refers to a city, or to some transport and logistics-oriented area in a city, that is associated with goods movement in, out, and through the area. Although the definition of a gateway is typically focused on goods movement, a more holistic view is adopted with consideration of the movements of people and the environmental implications of all movements. The relevance of this view is based on the interdependence of commercial and persons mobility, because all moves are happening within the same transport network, and is based on considerations of quality of life in a gateway city. Hamilton, Ontario, Canada, was chosen to test these concepts. Hamilton had a suitable geographical location, a busy port, an international airport, good highway and railway access, and an educated labor force. The gateway prospects for Hamilton were given perspective through a study of other prominent gateways that distilled success factors. Analytical work focused on multiregional economic impact modeling to assess the direct and indirect effects of Hamilton's potential evolution as a gateway. Local-level analysis, through integrated urban modeling and simulation of scenarios, stressed the impact of gateway development on commercial goods movement, auto commuting levels, emission levels, and transit ridership. Increased emissions resulting from gateway economic development could be overcome with forward-thinking policy focused on the uncongested movement of goods and people, compact urban form, and enhanced public transit working in concert. The addition of light rail transit in Hamilton and the promotion of a compact urban form would be catalysts for sustainable local gateway development. Finally, gateway-oriented development in Hamilton will cause noticeable regional economic growth. The models that were developed can be calibrated for other cities, given appropriate data.

AbstractThe historical distribution of Glaucopsyche lygdamus (Doubleday) (Lepidoptera: Lycaenidae) in southern Ontario, Canada was analysed using three major databases. In southern Ontario, G. lygdamus includes (1) subspecies G. lygdamus couperi Grote that has expanded its range from the north since the 1940s and 1950s reaching Hamilton, Ontario, Canada in 2012; (2) a non-expanding population on the Norfolk Sand Plain, Ontario, Canada that appears phenotypically closest to G. lygdamus couperi, but with some wing marking characters that are transitional to the more southern subspecies G. lygdamus lygdamus; and (3) rare and local pre-expansion populations referable to G. lygdamus couperi that occurred in the Ottawa Valley and Bruce Peninsula, Ontario, Canada in alvar woodlands, and possibly also on lakeshore dunes. The very rare and local occurrences of silvery blue in southern Ontario in the past is in direct contrast to its increasing abundance in the area in present times, but the genetic and phenotypic diversity of silvery blue may be declining due to genetic mixing with and/or to the effect of increasing parasitoids from the expanding race.

Background: The lasting impact of colonization contributes to the disproportionate rates of homelessness experienced by Indigenous people in Canada. Methods: This study used participatory mixed methods to evaluate an urban, Indigenous-led Housing First program in Ontario to fill knowledge gaps on wise practices addressing the unique dimensions of Indigenous homelessness. Using concept mapping, staff perspectives were engaged to generate 65 unique statements describing program delivery and their interrelationships using a six-cluster map. Results: ‘Team’s Professional Skills’ and ‘Spiritual Practices’ rated high in importance (mean = 4.75 and 4.73, respectively), and feasibility (mean = 4.31 and 4.33, respectively). While fairly important, ‘Partnerships and Agency Supports’ was ranked least feasible (mean = 3.89). On average, clusters rated higher in importance than feasibility. Conclusion: Concept mapping draws from local knowledge, elicits strong engagement, and captured the holistic and client-centred approach of an Indigenous Housing First Model.

Contexte : Des mesures de santé publique, telles que la distanciation physique et la fermeture des écoles et des services non essentiels, ont été rapidement mises en œuvre au Canada pour freiner la propagation de la maladie à coronavirus 2019 (COVID-19). Nous avons cherché à étudier les conséquences des mesures d'atténuation pendant la vague printanière de COVID-19 sur l'incidence d'autres virus respiratoires confirmés en laboratoire à Hamilton, en Ontario. Méthodes : Tous les échantillons d'écouvillons nasopharyngés (n = 57 503) soumis à un dépistage systématique du virus respiratoire dans un laboratoire régional desservant tous les centres hospitaliers de soins de courte durée de Hamilton entre janvier 2010 et juin 2020 ont été examinés. Les tests de dépistage de la grippe A et B, du virus respiratoire syncytial, du métapneumovirus humain, du virus para-influenza I-III, de l'adénovirus et du rhinovirus/entérovirus ont été effectués systématiquement à l'aide d'un panel multiplex de virus respiratoires par réaction en chaîne par polymérase mis au point par le laboratoire. Un modèle de régression linéaire bayésien a été utilisé pour déterminer la tendance des taux de positivité de tous les échantillons de grippe au cours des 26 premières semaines de chaque année de 2010 à 2019. Le taux de positivité moyen de l'inférence bayésienne a été comparé au taux de positivité hebdomadaire des échantillons de grippe rapporté en 2020. Résultats : Le taux de positivité de la grippe en 2020 a fortement diminué après la mise en œuvre d’interventions relatives à la COVID-19 à l'échelle de la population. Les semaines 12–26 ont rapporté 0 % de positivité pour la grippe, à l'exception de 0,1 % rapporté la semaine 13. Conclusion : Les mesures de santé publique mises en œuvre pendant la pandémie de COVID-19 ont été associées à une incidence réduite d'autres virus respiratoires et devraient être envisagées pour atténuer la gravité de la grippe saisonnière et des pandémies dues à d'autres virus respiratoires.

AbstractThis paper explores how local government structure affects policy co-ordination. It compares the delivery of economic development services in two Ontario cities. In London, a specialized agency is the lead, but lacks full functional control, while in Hamilton policy control is consolidated in a single municipal department. The findings support the hypothesis of those who argue in favour of general-purpose governments, as the municipal hierarchy in Hamilton was instrumental in achieving policy co-ordination. Proponents of specialization argue that it limits the need for co-ordination between governments but, as the London case demonstrates, this logic breaks down when there are too many players with too few responsibilities.

Abstract Water samples were collected in the summer of 2001 for microcystin analysis, nutrients and algal enumeration from Hamilton Harbour (Lake Ontario), Wendt Beach (Lake Erie) and Presque Isle (Lake Erie). Microcystin concentrations varied largely and were present at acute toxicity levels only in some wind-concentrated scums of blue-green algae (>90% Microcystis, primarily M. botrys, M. viridis and some M. wesenbergii) in Hamilton Harbour. In Hamilton Harbour, microcystin-RR was the main microcystin with microcystin-YR and -LR also present. The two samples of August 17 and September 7, taken during the peak of the cyanobacterial bloom, contained 60 and 400 μg/L, respectively. A few dying birds were seen in the Hamilton scums. The concentrations of microcystins at the Lake Erie sites were less than 1 μg/L, yet dead birds were common. The major limitation with this approach is that current analysis (ELISA and HPLC) methods are unable to measure covalently bound microcystins, the form that is assimilated into the food chain.

This Hamilton, Ontario today displays stark socioeconomic disparities in health which pattern along north/south lines within the city. Diphtheria provides a useful lens for examining the historical nature of these socioeconomic disparities. Data were collected from death registrations for the period 1900 to 1921 and 321 deaths were mapped in ArcMap. Diphtheria mortality rates were higher in the north overall; however, no difference was found for the 5–16 year age group (school age). Higher mortality in children under age five in the north due to factors associated with low SES may explain the differing rates. These results demonstrate the social inequalities in health that existed in early-twentieth century Hamilton and their geographic dimension.

This paper explores the possibility of renovating the FirstOntario Centre in Hamilton, Ontario, a large hockey stadium that can also be used to host concerts and similar events. Presently the facility is too big to fit the needs of Hamiltonians in a sustainable way and the excess space/seating raise the cost of maintenance unnecessarily while leaving the arena severely underutilized at around an average of just over 50% utilization. In other words, FirstOntario Centre is a case study in regenerating excellence. We describe the challenges and potential solutions to repurpose this space in order to regenerate social, economic, and environmental excellence in the heart of this mid-sized Ontario city. This case study can inform others seeking to reinvigorate attributes of livable cities.
