"Northern Gateway": Film, Tourism, and the Canadian Vacation by Dominique Brégent-Heald is a comprehensive study of the use of film to promote Canada as a tourist destination. The book explores the history of Canadian government agencies using film to attract American tourists, a topic that has been overlooked by historians. The author examines a wide range of films, from government-sponsored productions to amateur films, and covers the period from the 1890s to the 1950s. While the study does not provide a comparative analysis with other countries, it convincingly demonstrates the early adoption of film as a tourism promotion tool in Canada. The book also highlights the role of key individuals and their networking efforts in shaping the industry. However, it leaves some aspects of tourism film history underdeveloped and raises questions about the competing interests of different levels of government and the portrayal of Canada's diverse population in tourism films.

CULTURE ,CANADIAN federal government - Abstract
Elsewhere (as shown in Chapter 4), Malraux delivered speeches about Culture and the Arts, privileging themes such as destiny and praising the renewed friendship between France and Canada. Malraux visited Quebec during the era of Georges-Émile Lapalme, who (beginning in 1961) was the first Minister of Culture for the province of Quebec, and counterpart to Malraux in that position (there was no minister of culture as such within the Canadian federal government, only in the ten provinces).

In this welcome monograph, Felicity Barnes expands our understanding of the marketing and commodity culture that tied the dominions and the metropole together in the interwar period especially. Selling Britishness: Commodity Culture, the Dominions and Empire: By Felicity Barnes. Perhaps Barnes' largest point of argument is that, while ostensibly dominion marketing was intended to boost Canada, Australia and New Zealand's economies and thus their national autonomy, it worked to build a shared Britishness.

The practitioner-patient interview has been the subject of several studies in the world of medicine and in the field of teaching languages for specific purposes It has been considered one of the most critical oral genres in language teaching for medical-health purposes. Every health professional has to know and understand why the patient has come for a consultation; they must have the necessary skills to obtain as much information about the patient's health problem as possible, and if necessary, they have to perform a physical examination. The practitioner-patient interview is divided into several steps. Each step consists of a specific task with its specific objectives for the practitioner. For about fifteen years, the French Language Centre of McGill University, an English-speaking university in Montreal, Canada, has been offering French courses to students specializing in different areas of the Faculty of Health Sciences and Social Work who wish to do their clinical placements and pursue their professional career in the province of Quebec. Most of McGill’s students are native English speakers from different parts of Canada and the United States or international students whose first language is not necessarily English. One of the most important oral genres which must be taught to these students is the practitioner-patient interview in French, since one of their principal tasks as healthcare professionals will to interact with patients. Furthermore, students who have obtained a degree in any healthcare profession from an English-speaking university in the French-speaking province of Quebec must take a French language exam offered by the Office québécois de la langue française (OQLF). In one of the activities of this exam, the candidates must interview a patient or a caregiver in French. Therefore, this constitutes another reason to teach the practitioner-patient interview to our students. Unfortunately, there is little extant literature on how to teach students to carry out a practitioner-patient interview in French as a second language. Moreover, the possibility of recording actual interviews for use in class is practically impossible to respect patient confidentiality. This paper aims to share with the scientific community and with other language for specific purposes instructors how the practitioner-patient interview is taught at McGill University to non-native French speakers who wish to work in Quebec.

This article is an overview and reflection of the findings of an evaluative study conducted on a program called "Techno-Covid Partnership" (TCP) implemented in April 2020 at the Centre Hospitalier de l'Université de Montréal (CHUM) in Montreal, Canada. In the context of the COVID-19 pandemic, the CHUM decided in April 2020 to implement telehealth, virtual care, and telemonitoring platforms and technologies to maintain access to care and reduce the risks of contamination and spread of COVID-19 as well as to protect users of health services and health professionals. Three technological platforms for telehealth and remote care and monitoring have been developed, implemented, and evaluated in real-time within the framework of the TCP program. A cross-sectional study was carried out in which a questionnaire was used and administered to users of telehealth platforms including patients and healthcare professionals. The methods and results of the study have been published previously published. In the completion of the two articles published in this context, in this paper, we briefly recall the context of the study and the method performed. The main focus of the paper is on presenting a critical overview and reflection on the major findings of our evaluation of the use of telehealth platforms from the point of view of patients and health professionals and discuss certain paradoxes i.e., the advantages, challenges, recommendations, and other perspectives that emerged in this study.

COMBINED sewer overflows ,SEWERAGE ,GREEN infrastructure - Abstract
Combined sewer overflow (CSO) control strategies are commonly selected relying on optimization or multicriteria analysis. A methodology is proposed in this paper for selecting and evaluating the solutions to mitigate stormwater problems in combined sewer systems (CSSs) based on the understanding and rigorous diagnosis of the causes of the observed problems using hydrological/hydraulic simulations. The methodology was applied to a sewer catchment near Montreal (Canada) in order to reduce the magnitude and recurrence of sewer surcharge and local flooding without increasing the recurrence of CSOs. Two types of control strategies were considered: (1) large-scale solutions, i.e., redirection of stormwater inflows and separation of the CSS; and (2) source control solutions including both green and gray infrastructure. These solutions were evaluated through a comparative analysis of nine scenarios. Based on the results, source control solutions could be considered as the most effective interventions on the studied catchment for eliminating or significantly reducing the occurrence of sewer surcharge (from an average of 6.7 to 2.6) and surface flooding on local streets (from an average of 3.5 to 0.4 per year). The developed methodology is a valuable tool to be applied to other urban drainage catchments that encounter problems similar to those observed on the studied catchment. [ABSTRACT FROM AUTHOR]

The global population continues to grow, which expands demand for raw materials. Meanwhile, governments are developing circular economy strategies within cities and their industries. A circular economy utilizes refurbishing, reusing, remanufacturing, and repairing of products and materials. For companies, this involves to set targets and to rethink their supply chain. This paper seeks to model an exhaustive multi-echelon closed-loop supply chain (CLSC) network. This network functions within uncertainty, and the model optimizes three different objectives. The first objective function maximizes the network's profit; the second objective function minimizes network emissions. The last objective function maximizes job positions created by the network. Optimizing three contradicting objectives is a problem, so an augmented epsilon constraint method is applied to improve the model. Given the rise of fast fashion in developed countries, this model is used in the clothing industry in Montreal, Canada. The model includes three scenarios over five years with two types of products. The result shows the attractiveness of such a network for companies looking for profit, sustainability, and entrepreneurship in the garment industry. [ABSTRACT FROM AUTHOR]

Research on microscopic bicycle flow parameters (speed, headway, spacing, and density) is limited given the lack of methods to collect data in large quantities automatically. This paper introduces a novel methodology to compute bicycle flow parameters based on a LiDAR system composed of two single-beam sensors. Instantaneous mid-block raw speed for each cyclist in the traffic stream is measured using LiDAR sensor signals at seven bidirectional and three unidirectional cycling facilities. A Multilayer Perception Neural Network is proposed to improve the accuracy of speed measures. The LiDAR system computes the headway and spacing between consecutive cyclists using time-stamped detections and speed values. Estimation of density is obtained using spacing. For model calibration and testing, 101 hours of video data collected at ten mid-block sites are used. The performance of the cyclist speed estimation is evaluated by comparing it to ground truth video. When the dataset is randomly split into training and test sets, the RMSE and MAPE of the speed estimation method on the test set are 0.61 m/s and 7.1%, respectively. In another scenario, when the model is trained with nine of the ten sites and tested on data from the remaining site, the RMSE and MAPE are 0.69 m/s and 8.2%, respectively. Lastly, the relationships governing hourly flow rate, average speed, and estimated density are studied. The data were collected during the peak cycling season at high-flow sites in Montreal, Canada; However, none of the facilities reached or neared capacity. [ABSTRACT FROM AUTHOR]

The degradation of a concrete structure in northern climate is mainly due to the corrosion of steel reinforcements and cumulative damages from mechanical loading. Infrastructure managers heavily rely on ratings obtained from visual field surveys and the interpretation of inspection reports to predict the future structure states and to plan appropriate maintenance and replacement activities. In this paper, an effective structure management framework is proposed, combining information from on-site visual inspections and predictions from a nonlinear chloride transport model, to improve diagnostics for preventive maintenance. Meaningful predictions were obtained by using climatic data from neighboring weather stations and characterising the concrete transport properties with non-destructive tests. The chloride profiles from the model can be validated with core-drilled samples, if available. Predictions from the model were used to estimate the probability of the corrosion initiation and the condition states of the structural elements to complement the visual inspection observations. Finally, the ratings of each element were combined to obtain a global rating of the structure by considering the relative criticality of each element for the safety and the performance of the structure. The methodology was applied to a typical bridge in Montreal and demonstrated good agreement between the model predictions. [ABSTRACT FROM AUTHOR]

The concept of Positive Energy Districts (PEDs) has emerged as a promising approach to achieving sustainable urban development. PEDs aim to balance the energy demand and supply within a district while reducing the carbon footprint and promoting renewable energy sources. Urban–Industrial Symbiosis (UIS) is another approach that involves the exchange of energy and resources between industrial processes and nearby urban areas to increase efficiency and reduce waste. Combining the concepts of PED and UIS can create self-sufficient, sustainable, and resilient districts. As the analysis and implementation of such systems are barely studied in North America, this research study was structured to fill the gap by evaluating the financial and environmental advantages of this combination. This study proposes a methodology to design a heat transmission system; then, it is applied to the case of a paper-making factory and a multifunctional heritage building in Montreal, Canada. The results show that the building's new heating system can generate sufficient heat while emitting near-zero direct emissions. Overall, this paper argues that combining the concepts of PED and UIS can lead to a more sustainable and resilient urban area, and provides a roadmap for achieving this goal. [ABSTRACT FROM AUTHOR]

This paper presents an investigation into the interoperability of 3D building energy data management, delivery, processing, and visualization via web clients using Open Geospatial Consortium – Application Programming Interface (OGC API) standard-based data models and web interfaces. Specifically, the OGC API – 3D GeoVolumes enable access to 3D city model geometries and semantics on the web, the OGC API – Features support the 2D version of the same geospatial data, the OGC API – Processes are used for CityGML analytics and building energy computation with the SimStadt urban simulation software and the OGC SensorThings API is utilized to manage related spatiotemporal or time-series datasets. The efficacy of this approach has been demonstrated in the OGC Testbed 18 Innovation Program, which highlighted the capacity of OGC API web services to synchronize building energy data and computation results between client and server for the case study of Helsinki, Finland, and Montreal, Canada. The advantages of using OGC API services for 3D building energy data interoperability are discussed, and it is suggested that the use of OGC API be promoted to the general public as well as extended to other domains and on a larger scale in future research.

In response to Canada's commitment to reducing greenhouse gas emissions and to making pathways to achieve carbon neutral buildings, this paper presents two real case studies. The paper first outlines the potential of trees to absorb CO
2 emissions through photosynthesis, and the methods used for the estimation of their annual carbon sequestration rates. The net annual carbon sequestration rate of 0.575 kgCO2 eq/m2 of tree cover area is considered in our study. Then, this paper presents the carbon life cycle assessment of an all-electric laboratory at Concordia University and of a single-detached house, both located in Montreal. The life cycle assessment (LCA) calculations were performed using two software tools, One Click LCA and Athena Impact Estimator for Buildings. The results in terms of Global Warming Potential (GWP) over 60 years for the laboratory were found to be 83,521 kgCO2 eq using One Click LCA, and 82,666 kgCO2 eq using Athena. For the single-detached house that uses natural gas for space heating and domestic hot water, the GWP was found to be 544,907 kgCO2 eq using One Click LCA, and 566,856 kgCO2 eq using Athena. For the all-electric laboratory, a garden fully covered with representative urban trees could offset around 17% of the total life cycle carbon emissions. For the natural gas-powered single-detached house, the sequestration by trees is around 3% of the total life cycle carbon emission. This paper presents limits for achieving carbon neutral buildings when only the emissions sequestration by trees is applied, and discusses the main findings regarding LCA calculations under different scenarios.

SMALL business ,INDUSTRY 4.0 ,FLOUR mills - Abstract
In Industry 4.0 context, data valorisation allows industries to develop new capabilities, create competitive advantages and achieve manufacturing sustainability, but technological infrastructures are needed to support system interoperability and to manage datas. These infrastructures are not enough mature in many industrial environments, especially in small and medium enterprises (SMEs). Technology integration is challenging due to system and information heterogeneity, and even more so in SMEs that have constraint environment and which lack specific research study. . Although several approaches have been proposed, the literature lacks empirical evidence of the adoption of new technologies in SMEs. This paper presents a guideline for implementing a Cyber- Physical system (CPS) architecture in an SME and its application in an organic flour mill in Montreal. The case study provides evidence of the possibility to implement a CPS architecture in SMEs and can serve as an inspiration for SME to develop an Industry 4.0 strategy. [ABSTRACT FROM AUTHOR]

DISTRIBUTION (Probability theory) ,DIGITAL technology ,TAYLORISM (Management) ,ELECTRONIC commerce ,ETHNOLOGY research ,SOCIAL services - Abstract
Amazon is one of the largest e-commerce corporations in the world and has built a reputation for fast, low-cost service. To rapidly and efficiently move goods from production to consumption, however, Amazon relies on a logistics network that entails significant investments in infrastructure (physical and human) and these investments present a challenge for capital accumulation. In this paper, I examine the labour practices that Amazon employs within its distribution work spaces to address this challenge. The analysis is based on a case study of Amazon's distribution facilities (fulfilment centres and delivery stations) in Montreal, Quebec. It draws on ethnographic research as a community organizer and semi-structured interviews with workers (present and former), trade union representatives and public policy experts to identify Amazon's key strategies. Building on past studies on the platform economy, I illustrate how Amazon relies on 'digital Taylorism' (Staab & Nachtwey, 2016), involving the use of digital technologies to structure and control the labour process and surveil workers, as a key strategy. However, I further illustrate how Amazon seeks to balance the harmful effects of digital Taylorism with what I term 'corporate keynesianism' (i.e., social welfare benefits) to attain a 'labour fix', i.e., the steady supply of precarious, compliant labour needed to sustain the logistics machine.

Opened to traffic on 1 July 2019, the new Samuel De Champlain Bridge represents one of the largest infrastructure projects in North America. The rapidly deteriorating condition of the original Champlain Bridge in Montréal led the Government of Canada to accelerate its replacement and ultimately awarded a contract to the Signature on the Saint Lawrence Group, in 2015, to deliver a new replacement crossing. The project was fast-tracked, with a schedule of only 48 months from design to bridge opening. Due to its geographical location, this lifeline structure faces unique hazards including extreme cold temperatures, ice abrasion, de-icing salt attacks, wind, vessel collision, scour and seismic, while meeting its design life of 125 years. Sustainability and durability are also important project requirements. The 3.4 km long bridge is comprised of three independent structures: the 529 m long, asymmetric cable-stayed bridge (which features a single 169 m high tower), the 762 m long east approach and the 2044 m long west approach. The owner used a public–private partnership procurement model and the project was delivered using the design–build delivery method. An overview of this Can$2.4 billion mega project is provided in this paper, and the design and build solutions to overcome the suite of technical and schedule challenges are discussed.

EARTHQUAKE hazard analysis ,ALLUVIUM ,EARTHQUAKE damage - Abstract
Greater Montreal is situated in a region with moderate seismic activity and rests on soft ground deposits from the ancient Champlain Sea, as well as more recent alluvial deposits from the Saint Lawrence River. These deposits have the potential to amplify seismic waves, as demonstrated by past strong, and recent weak, earthquakes. Studies based on the 2015 National Seismic Hazard Model (SHM5) had estimated losses to residential buildings at 2% of their value for an event with a return period of 2475 years. In 2020, the seismic hazard model was updated (SHM6), resulting in more severe hazards for eastern Canada. This paper aims to quantify the impact of these changes on losses to residential buildings in Greater Montreal. Our exposure database includes population and buildings at the scale of dissemination areas (500–1000 inhabitants). Buildings are classified by occupancy and construction type and grouped into three building code levels based on year of construction. The value of buildings is obtained from property-valuation rolls and the content value is derived from insurance data. Damage and losses are calculated using Hazus software developed for FEMA. Losses are shown to be 53% higher than the SHM5 estimates. [ABSTRACT FROM AUTHOR]

Veteran community engagement is an evolving discipline informed by traditional community-based participatory research, veteran studies, and veterans themselves. This Special Issue suggests that research collaborations including military veterans, soldiers, and their families as co-researchers is a critical next step toward a design thinking perspective in social and healthcare systems for this population. This Special Issue was conceptualized through a veteran community-academic partnership formed over a decade ago. This partnership hosted several Warrior Summit conferences from 2013 to present, with the last of this series calling for academic contributions. The resulting papers drawn from the conference and other authors form this issue, and include a wide range of topics: veteran microdosing and psychedelic self-medication; a historical view of the impact of education exchange between U.S. and South Korean military nurses; strategies for engaging veterans in research of a theater-based intervention for PTSD; interprofessional approaches to addressing veteran identity considerations through collaborations between chaplain service and psychologists in the VA Healthcare System; an international perspective exploring a community collaborative with veterans in Montréal, Canada; efforts to build long-term and sustainable models for veteran engagement in health services research; community-engaged strategies to address veteran homelessness within broader housing stability efforts; and examining the role of veteran peer mentorship programs in alcohol recovery. These projects represent an emerging movement and offer a multidisciplinary roadmap toward honoring veterans voices in research, clinical services, and program development. [ABSTRACT FROM AUTHOR]

The potential of semiotics to theorize and analyze the field of sustainable architecture is still largely unexplored. This paper uses a triadic structure for defining sustainable design signs and distinguishes two separate modes of sustainable design reasoning: namely deductive and abductive sustainable design reasoning. This theoretical framework is used to analyze two architectural projects submitted for an international design competition in Montreal, Canada. The architectural texts, considered in this paper the representamen of the signs, prove to be indicative of the mode of reasoning deployed. The analysis also reveals that the mode of reasoning used dictates the types of signs produced, the role designed-objects have in the signs, as well as the functional possibilities design elements perform in the project. The paper proposes that deductive sustainable design reasoning brings to a halt the process of semiosis – presenting a status-quo approach – and that abductive sustainable design reasoning allows semiosis ad infinitum – presenting a future driven outlook. Additionally, a gap appeared between the open form of critical judgement proposed for competitions and the conceptual fixation inherit in deductive sustainable design reasoning. This paper presents a theoretical contribution that provides new possibilities for researchers to model and analyze sustainability in design projects. [ABSTRACT FROM AUTHOR]

VISION ,VENTRILOQUISM ,ORGANIZATION ,ALTERNATIVE schools - Abstract
Organizations have long been treated as stable and fixed entities, defined by concrete buildings, catchy names, and strategic goals neatly written on paper. The Communicative Constitution of Organizations (CCO) school proposes an alternative, practice-grounded conceptualization for studying organizations as emerging in communicative (inter)actions. In so doing, CCO invites organizational scholars to trace back organizational phenomena to how they are communicated into existence. The concept of ventriloquism can help us explain the communicative constitutive view as it depicts how various elements of a situation are communicated into being and make a difference in interaction. However, ventriloquism lacks a proper methodological outline. Taking employee conversations about visions—a classic constituent of organizations—as our venue, we created a four-step framework for ventriloquial analyses and explored how visions are talked into existence. In this paper, we introduce and illustrate our analytical framework, showing how to identify, order, and present ventriloquial effects. We thus provide organizational (communication) scholars with a new methodological tool that facilitates the systematic inquiry into organizing and the organized from a communicative constitutive perspective.

Nowadays, air conditioning consumes, on average, around one-fifth of the total power used in buildings globally. The present paper aims to provide the present status on the employment of Earth-to-Air Heat eXchangers (EAHX) to contain the consumption of energy and to reduce the effect on the environment in response to the Montreal and Kyoto protocols in a way to achieve cleaner energy production with a low Global Warming Potential (GWP) and a low ozone depletion potential (ODP). Different peculiarities and applications (direct or hybrid) are critically analyzed and reviewed. Specifically, in this paper, the different hybrid applications presented in the literature, where the Earth-to-Air Heat eXchangers are coupled to advanced systems, are reviewed. Finally, an IoT-based EAHX control system plan is reported and discussed to optimize energy efficiency and thermal comfort to suit operating conditions under different time zones.

The assessment of infrastructure conditions is at present a topic of great interest and importance, as well as great challenge. This paper presents a case study of the Samuel De Champlain Bridge (Montreal, QB, Canada), an outstanding stay cable bridge equipped with a comprehensive monitoring system (SHM). Among other SHM features, particular attention was paid to implementation of a strategic corrosion monitoring system. This paper intends to describe the concept design, implementation and data interpretation. Here corrosion sensors have been embedded during construction stage to monitor long term evolution of key electro‐chemical parameters for controlling deterioration of materials. Furthermore, these sensors measure stray current interference generated from the rail system that can cause corrosion. In both cases, abnormal values would warn the owner of the associated increased risk of corrosion. This gives them the possibility to take corrective measures to protect the structure before corrosion becomes a serious threat. [ABSTRACT FROM AUTHOR]

This paper is offered as a complementary adjunct to the many treatments of the electronic and photonic properties of cubic III–V and II–VI compounds appearing in the literature. These crystals typically exhibit piezoelectricity, due to the molecular dissymmetry, thereby allowing the inclusion of classical mechanical/acoustic features along with the quantum. We discuss the history of this modality and then illustrate its use by applying it to an electro‐elastic problem that has the estimable virtues of having an exact solution, along with wide practical applicability: determination of the piezocoupling values governing the excitation of thickness vibrations in thin cubic films or plates of arbitrary crystallographic orientation by electric fields directed either along, or lateral to, the thickness. Explicit results are given for orientations along the great‐circle paths connecting the principal directions [100], [110], and [111]. The formalism is then applied to GaAs as an example; it is further demonstrated that various results, such as the orientational variations of piezocoupling factors, are generally applicable to other members of the III–V and II–VI families by scaling. Ancillary aspects, such as errors due to misorientations, nonlinearities, and equivalent circuit representations, are described and discussed. This work is dedicated to Gerald W. Farnell (1925–2015), Prof. Emeritus, McGill University, Montréal, Canada. [ABSTRACT FROM AUTHOR]

As cities work to accelerate sustainable-transport transitions, the expansion of cycling networks has become a significant topic of debate. Even as cycling modal shares are increasing across many North American contexts, “bikelash” (i.e., community opposition to cycling facilities) remains prevalent. In this paper, we draw from qualitative questionnaire data and quantitative travel data from Montréal, Québec to contribute a situated understanding of factors influencing both positive and negative social perceptions of cycling infrastructure. Our analysis confirms general trends that contribute to residents’ overall satisfaction with recent cycling interventions, including enhanced safety considerations and family-friendly infrastructure. We also identify particular sources of bikelash that require deeper consideration, including conflicting ideas about the impacts of cycling facilities on local businesses, divergent opinions about the planning process, perceived inequities in the distribution of cycling networks, as well as issues of seasonality and modal integration. These findings can be of interest to practitioners and decision makers working to support sustainable-mobility transitions, including recommendations on public-communication and consultation processes, winter cycling facilities, integrated infrastructure for active travel, as well as the inclusion of socialequity and critical-disability perspectives.

CULTURAL pluralism ,SOCIAL context ,UNMARRIED couples - Abstract
In a social and political context marked by increasingly polarized attitudes towards immigration and ethnic diversity, the paper uses the results of two research projects conducted ten years apart in Brussels and Montréal to reflect on methodological issues. The paper discusses two themes to show how to engage methodologically within a changing context, both theoretically and politically, and how various methodological choices might be used to fill some knowledge gaps. The first theme concerns the choice of research methods, and the type of knowledge they produce. The second theme addressed in this paper stresses the importance of paying more attention to the context where the research takes place, a process denoted here by the term situating. Two different interview methods are central to the discussion: in-depth interviews and 'on-the-spot' short interviews. The paper contrasts their use in relation with each project's research objectives. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to present a methodology for the design and predictive control of thermal zones with bifacial semi-transparent photovoltaic (STPV) windows, motorized venetian blinds (MVB), and hydronic radiant floor heating (HRFH). Solar gains and daylight are controlled by the blind tilt angle, β, of the motorized venetian blinds, for passive heating and natural daylighting in the zone. Near-optimal temperature setpoint strategies control the room temperature with hydronic radiant floor heating, which promotes preheating overnight, before the morning peak demand period of the grid in Quebec (6-9 AM), and in the afternoon, before the evening peak period of 4-8 PM. We can increase the energy flexibility in the building electricity demand profile with a predictive control model of window and blind transmittance and zone setpoint profile, based on a one-day ahead prediction for different design days in the heating season. An explicit finite difference thermal network model is used to predict heating loads and the building temperature profile associated with the thermal response of the zone. The energy flexibility in the demand profile is quantified by a building energy flexibility index (BEFI) [2]. The concrete slab thickness of the hydronic heating system will be analyzed parametrically to further improve the energy flexibility and efficiency of the thermal zone. Four different slab thicknesses of concrete are considered, including 5, 8, 10, and 12 cm (1.97, 3.15, 3.94, 4.72 in), while three different window-to-wall ratios (%) are considered. A 10 cm (3.94 in) thick slab and 32% WWR produces a BEFI = 100% for both morning and peak periods, for a cold and clear February day, in Montreal; completely displacing the heating demand for the peak periods. There are several pre-determined design variables for this zone, including the building orientation and the coverage ratio of the STPV (%). Simulations are based on a typical zone at a test facility on Concordia's Loyola campus, which will be validated experimentally in the future. [ABSTRACT FROM AUTHOR]

This paper examines the growth of the Olympic Games against that of former host cities to understand whether this mega-event may have 'outgrown' its hosts. The increasing hosting requirements and governments' expansive use of mega-events as tools for urban development would suggest that the 'Olympic city' – a term we use for describing the size of the Olympics as hosted in different cities over the decades – has grown at a faster rate than former host cities. The analysis contrasts historical indicators that capture the evolving size of planning for the event based on four dimensions – sport, spectators, marketing and costs – as well as the urban dimension of hosting experiences (venues and infrastructure) with city trajectories based on demographic and economic indicators. This is done through a longitudinal analysis of former Olympic host cities from the 1960s and 1970s and from which continuous longitudinal data are available: Tokyo, Munich, and Montreal. The findings indicate that the Olympic city has grown more strongly than these former host cities, although not uniformly across trajectories. This gives evidence for the need to review the size of mega-event impacts if they ought to continue to generate interest in hosting them in the future. [ABSTRACT FROM AUTHOR]

BUILT environment ,SPATIAL resolution ,LOCAL knowledge - Abstract
Large-scale agent-based microsimulation platforms, increasingly used in transportation demand modelling, require fully enumerated and spatialized lists of the population and its sociodemographic characteristics as input. The quality of the synthetic population, measured as its ability to reproduce the sociodemographic characteristics of the real population and their spatial distributions, is thus a determinant factor of the model reliability. While many efforts were devoted to improving the sociodemographic accuracy of synthetic populations, less attention was paid to perfecting their spatial precision. Conventional spatialized population synthesis methods, where the generation and spatialization processes are separated, are vulnerable to inconsistencies between zonal synthetic populations, and the built environments on which they are then distributed. These methods also present transferability issues that lie in their high reliance on rich spatialized datasets and knowledge of the local context. Hence, we propose an integrated multiresolution framework (IMF) that overcomes the limitations of the conventional framework (CF) by its ability to directly generate synthetic populations at the building resolution with minimal data requirements. The IMF includes an extension of an optimization-based method to multiresolution applications where any number and aggregation of spatial resolutions can efficiently be controlled. The CF and the IMF are applied to generate synthetic populations for Montreal, Canada. We define and measure sociodemographic accuracy, spatial precision, overall quality, and building-resolution fit of the synthetic populations to compare the frameworks' performances. Despite a small loss in accuracy, the IMF achieves drastically better spatial precision, overall quality and building-resolution fit of synthetic populations, compared to the CF.

The passing of Professor Arthur Getis in May of 2022 initiated a number of events to both reflect on and remember the tremendous contributions he has made over his career to geographical systems more broadly, but also spatial analysis, spatial statistics, regional science, geography and GIScience, among others. This began with a series of sessions at the North American Regional Science Council meetings held in Montreal, Canada in November of 2022, followed by an invitation from the editors of Journal of Geographical Systems, Manfred Fischer, Antonio Paez, and Petra Staufer-Steinnocher, to organize a special issue in his honor. Soon thereafter, an open call was initiated to solicit submissions to this special issue, seeking original contributions that overlap and complement the broad range of research undertaken by Professor Getis over a distinguished career and life. This paper offers an overview of prominent geographical systems work carried out by Professor Getis. Reflections on his many contributions are also detailed. A summary of the contributions to this special issue is given, along with final thoughts. [ABSTRACT FROM AUTHOR]

Supporting festivities in the urban realm are possibilities cities have to reduce risks of exclusion and to stabilise narratives of belonging while reducing uncertainty. They are convivial forms creating territorial belonging and inclusion, beyond differences. The paper focuses on urban rituals of inclusion in Montréal, Genève and Turin as practices that foster inclusion and belonging to the city, coping with turnover of inhabitants and the change of urban spaces. In our post-migratory and mobile societies, where uncertainty bears both risks and challenges, rituals fostering a common ground, a sensus communis, as they require participation, but not necessarily a formalised affiliation.

Background and objectives: Urban regeneration is a clear mirror that reflects urban thinking and planning in every national system. This process in Iranian cities is quite different from the other cities in the world. Many factors have been important in this process, but a major issue was socio-cultural groups and nationalities like it has seen and studied at Montreal, Canada by author. The aim of this paper is to reconsider city sustainable development theory by analyzing urban regeneration processes with emphasis on cultural diversity or internal ethnic groups in Tehran. Methods: An analytical-qualitative framework is used to acquire an understanding of the specifications involved. Through impartial observations on two cities (Tehran and Montreal) over more than five years, this paper attempts to understand the effects of cultural-ethnic groups as social capitals on changing urban spaces. Findings: The results revealed that there are not any real multicultural cities in Iran and Tehran is a sample of local-internal multicultural city which its people are not serious social capitals or human forces in urban planning, implementation, and changes. Therefore, cultural capitals, which are consequential to urban regeneration process, as in the case of Montreal, have not been formed in Tehran. Conclusion: These findings may provide urban policy-makers in Iran and Tehran with social important facts for regeneration planning development, which helps to improve social capitals of cultural-ethnic groups.

This paper proposes the concept of mapping-ofrenda, which envisions mapping as a form of mourning and remembering while living in the context of migration. Inspired by the traditional Mexican ofrenda, the mapping-ofrenda aims to collect, curate, and represent posthumous memories. It can be produced collaboratively or individually, built with physical or digital maps, shared with other people, or kept private, and be dedicated to a single deceased or to an entire community. Through the process of co-designing two online ofrenda-maps with two Latina-American women living in Montreal (Canada) we identified some of the potential of mapping-ofrenda, including its capacity to stimulate our memories and remember stories on the verge of disappearing, to ground them to places, and to share them with people that might live far away. Mapping-ofrenda can also be a way of making visible the global geography of migration through highly intimate memories and acknowledging both the very personal and the highly universal need to remember and grieve. Finally, the main value of mapping-ofrenda in the context of migration, may be its capacity to reactivate and strengthen existing links and connections between people that are still alive but that may live far away.

The vital role of honeybees in pollination and their high rate of mortality in the last decade have raised concern among beekeepers and researchers alike. As such, robust and remote sensing of beehives has emerged as a potential tool to help monitor the health of honeybees. Over the last decade, several monitoring systems have been proposed, including those based on in-hive acoustics. Despite its popularity, existing audio-based systems do not take context into account (e.g., environmental noise factors), and thus the performance may be severely hampered when deployed. In this paper, we investigate the effect that three different environmental noise factors (i.e., nearby train rail squealing, beekeeper speech, and rain noise) can have on three acoustic features (i.e., spectrogram, mel frequency cepstral coefficients, and discrete wavelet coefficients) used in existing automated beehive monitoring systems. To this end, audio data were collected continuously over a period of three months (August, September, and October) in 2021 from 11 urban beehives located in downtown Montréal, Québec, Canada. A system based on these features and a convolutional neural network was developed to predict beehive strength, an indicator of the size of the colony. Results show the negative impact that environmental factors can have across all tested features, resulting in an increase of up to 355% in mean absolute prediction error when heavy rain was present.

Objective: Gestational diabetes (GDM) is a form of glucose intolerance which manifests during pregnancy. There is lack of literature regarding the study of cognitive functions in GDM. Recent evidences suggests an increase in accumulation of serum Advanced glycated end products (AGE’S) during GDM. Accumulation of AGE’s in brain can induce changes in permeability of blood brain barrier and creates oxidative stress and inflammation that can alter cognitive functions. In this study we hypothesize that diagnosis of GDM in pregnancy is related to lower cognitive scores which is correlated to increased serum AGE’s level. Method: This was a cross sectional case control study which recruited 60 participants in total consisting of two groups with 30 participants in each - diagnosed cases of GDM and healthy pregnant controls. Subjects were recruited from OPD of Obstetrics & Gynecology department in a tertiary care hospital in South India at gestational age of 32–36 weeks. On the first appointment, biochemical parameters of Fasting plasma glucose (FPG) & HbA1C was measured in both groups. Serum was obtained for testing levels of N Carboxy methyl lysine (N-CML) (a form of AGE). On second appointment, pen and paper neurocognitive tests including Montreal cognitive tests (MOCA) and Trail making test (TMT A & B) was presented. Event related potentials (ERP’s) are time locked EEG wave signals produced in response to a sensory, motor or cognitive event. P300 is an “endogenous” ERP produced by cognitive processing in response to a stimuli presented to subject. P300 wave Latency and amplitude was recorded in both the groups as an objective marker of cognitive processing. Above mentioned biochemical and neurocognitive parameters were compared between both the groups and correlation analysis between serum AGE levels and neurocognitive parameters was performed using SPSS software. Results: Biochemical parameters of HbAIC & N-CML(A form of AGE) levels were increased in GDM group (HbA1C 6.01±0.30 and N CML 236.25 ± 68.9) vs Control group (HbA1C 4.11 ± 0.68 and NCML 198.42 ± 44.2). Scores in MOCA were significantly lower in GDM (28 (27–29)) group as compared to controls (24 (23–25)). GDM subjects took significantly greater time to perform TMT A (24.59 ± 2.60 s) test than controls (29.7 ± 1.72 s). Significant changes were not found in P300 Latency & amplitude in GDM group. Decreased MOCA scores and increased duration of TMT A attempt were correlated with increased serum AGE concentration in GDM group. Conclusions: Our study indicates the vulnerability of women suffering from GDM to cognitive impairment during pregnancy. Lower scores in cognitive tests were correlated to AGE accumulation in GDM women. [ABSTRACT FROM AUTHOR]

This paper is part IV of "towards a model of urban evolution". It demonstrates how the Toronto Urban Evolution Model (TUEM) can be used to encode city data, illuminate key features, demonstrate how formetic distance can be used to discover how spatial areas change over time, and identify similar spatial areas within and between cities. The data used in this study are reviews from Yelp. Each review can be interpreted as a formeme where the category of the business is a form, the reviewer is a group and the review is an activity. Yelp data from neighbourhoods in both Toronto and Montreal are encoded. A method for aggregating reviewers into groups with multiple members is introduced. Longitudinal analysis is performed for all Toronto neighbourhoods. Transversal analysis is performed between neighbourhoods within Toronto and between Toronto and Montreal. Similar neighbourhoods are identified validating formetic distance. [ABSTRACT FROM AUTHOR]

Global biodiversity is in crisis as a result of human activity. This biodiversity crisis has been well documented by scientists, recognized by world leaders, politicians, businesses, and citizens. Both the biodiversity and climate crises need to be addressed now. 2020 was when this change was supposed to start, with the 15th Conference of Parties (COP15) of the Convention on Biodiversity (CBD) meeting in Kunming, and the 26th Conference of Parties (COP26) of the UN Framework Convention on Climate Change meeting in Glasgow, but both meetings were postponed. COP26 was held a year late (November 2021), while COP15 was split into two, with the first part held in Kunming in October 2021, and the second part scheduled for Montreal in December 2022. This meeting in Montreal – arguably the most important in the CBDs history – must agree on the Post-2020 Global Biodiversity Framework (GBF), to reverse biodiversity loss. Failure to reach agreement in Montreal would ultimately be a failure of us all, with irreversible consequences for life on earth. Yet, with three months before the final deadline only 20% of text and two targets are agreed. This paper reviews the factors hindering progress on the agreement and suggests possible solutions.

Digital sequence information (DSI) is crucial to technological advancements in diverse product areas from agriculture to environment and therapeutics. Advances in DNA sequencing technology have made it possible to generate and share vast amounts of genetic information data of various organisms at the global level at a relatively low cost. Advocates of open science support open access to DSI of genetic resources stored in public and private databases in silos. Due to the existing conundrum over the application of ABS mechanism under the Convention on Biodiversity (CBD) and its Nagoya Protocol(NP) to intangible genetic data, much of the DSI usage is happening without obtaining Prior Informed Consent(PIC) of provider countries and communities, a mandatory requirement for access and utilisation of genetic material. This is hampering the negotiations under the CBD and NP framework for sharing of benefits of commercial utilisation of the resources with the resource providers. Allowing free access to genetic resource sequence information without PIC and Mutually Agreed Terms (MAT) will be detrimental to the interests of indigenous peoples and local communities who foster and preserve biodiversity in their jurisdictions. The paper examines the issues and arguments surrounding DSI and investigates the possibility and prospects of applying the ABS under the CBDNP framework to DSI. It will analyse the negotiations taking place under the United Nations Convention on Biodiversity as well as the decisions on DSI that arrived in the COP15(Committee of Parties) held in Montreal in December 2022.

The paper proposes a mathematical model to forecast the time needed during a continuous improvement (CI) project. To do this, the authors adapted the famous Lotka–Volterra model to the CI methodology. Also, the authors examined a Montreal company's database to simulate the CI's necessary time in the real world. Firstly, the model simulates a total of CI hours for the employees and the respective quantity of problems at the end of the project. And after, the authors compared the simulation results with the project real results. This work introduces a new model to forecast the CI's necessary time and discuss an innovative way to implement a CI project. This work also considers the advantages and difficulties of achieving a CI project based on a simulation. One of the work's main result is the discussion of the total CI hours performed by the employees: 130% of the simulation proposition. This quantity of hours leads to half of the problems estimated by the model: 42%. The normalized results showed a difference of 1.03% between the simulation and the observations in the real world.

Urban ecology is a promising research field in limnology, but we still need to evaluate how urban waterbodies can sustain biodiversity. In this paper, we present a comprehensive foodweb perspective of urban waterbodies in the city of Montréal (Québec, Canada). The research goals are to evaluate if biodiversity and community structure of foodweb components (phytoplankton, zooplankton, and macroinvertebrates) are valuable tools for assessing the ecological status of urban waterbodies and examine how they are controlled by multiple factors related to trophic status and habitat complexity (origin, water residence, macrophyte cover, fish, and management practices). Multiple factor analysis, correlations, and non-parametric tests were used to examine the relationships between the environmental factors and foodweb biological variables. Our case study confirms that urban waterbodies are important sources of biodiversity and reveals that foodweb-based biological indicators are reliable tools for the biomonitoring of urban waterbodies. Foodweb biodiversity and community structure were more influenced by habitat complexity than by trophic status. The key determinants of variation were the differences in water regime, management of temporary and permanent waterbodies, and contrasts in habitat complexity depending on pond origin (artificial or natural) and macrophyte cover.

Conventional construction materials which rely on a fossil-based, nonrenewable extractive economy are typically associated with an entrenched linear economic approach to production. Current research indicates the clear interrelationships between the production and use of construction materials and anthropogenic climate change. This paper investigates the potential for emerging high-performance biobased construction materials, produced sustainably and/or using waste byproducts, to enable a more environmentally sustainable approach to the built environment. Life-cycle assessment (LCA) is employed to compare three wall assemblies using local biobased materials in Montreal (Canada), Nairobi (Kenya), and Accra (Ghana) vs. a traditional construction using gypsum boards and rockwool insulation. Global warming potential, nonrenewable cumulative energy demand, acidification potential, eutrophication potential, and freshwater consumption (FWC) are considered. Scenarios include options for design for disassembly (DfD), as well as potential future alternatives for electricity supply in Kenya and Ghana. Results indicate that all biobased alternatives have lower (often significantly so) life-cycle impacts per functional unit, compared to the traditional construction. DfD strategies are also shown to result in −10% to −50% impact reductions. The results for both African countries exhibit a large dependence on the electricity source used for manufacturing, with significant potential for future decarbonization, but also some associated tradeoffs in terms of acidification and eutrophication.

Transit-oriented development (TOD) is characterized as compact, mixed-use, and pedestrian-friendly development around transit stations, aiming to balance land use and transportation, enhance sustainability, and improve public transport accessibility. There are various TOD assessment methods; each target one of these goals. This paper proposes a comprehensive approach that addresses TOD goals in a multistage assessment. In the first stage, we identify station areas' typology using weighted node, place, and tie indices based on the correlation between land use and transportation. Then, feasible station areas for enhancing density and diversity are selected using a canonical score. In the second stage, station areas' typology is defined by sustainability criteria and a TOD index. Then, the efficiency of selected station areas for compactness is assessed using Data Envelopment Analysis. Finally, public transport accessibility is optimized for these stations in the third stage. We investigate the effects of weighting indicators of the node–place model in the first stage and aggregation methods in the second stage. We conduct a feasibility and efficiency assessment for the typology of station areas in Metro Montreal. This study attempts to advocate a holistic perspective for TOD assessment with a case study implementation. [ABSTRACT FROM AUTHOR]
