FOREIGN EXPERIENCE IN MODERNIZATION AND RECONSTRUCTION OF TYPICAL POSTWAR HOUSING
Authors: Demkiv Myron , Popova Solomiya
Published: May 2021

The article presents the results of review and analysis of literature sources on the reconstruction and modernization of typical housing in the postwar period in Europe (Germany, France, Poland, Latvia, Lithuania, Estonia) and Russia. The main issues of its implementation are considered: energy efficiency, organizational and economic, architectural and planning. The organization of reconstruction and modernization of housing at the state level is described in detail, application of modern technologies during its implementation, as well as examples of implemented projects.

After the Second World War in many countries of the world and especially in the countries of the socialist camp there was a massive panel and brick housing construction on typical projects of the first generation with the use of industrial structures. In the early 70's it became clear that such buildings are obsolete, lost social attractiveness, and most importantly, efficiency. Analysis of the state of old buildings and the use of a multifaceted approach to the renovation and reconstruction of obsolete housing has led to the realization that the renovation of such buildings is more economical than new buildings in vacated areas and they are available to middle-income people. Foreign experience in the modernization and reconstruction of post-war housing convincingly proves this.

It should be noted that each European country finds its own ways to address organizational, technological and economic issues related to the reconstruction and modernization of residential buildings.

Based on the fact that the first post-war buildings on standard projects, as a rule, were carried out in whole arrays, their reconstruction should be based not only on residential buildings but also on the residential district or neighborhood as a whole. During the reconstruction of buildings should be considered traditional or historical features of the surrounding parts of the city. Particular attention should be paid to improving transport conditions, as the number of individual transport is constantly growing. Also important are the issues of insolation and aeration, which, together with the appropriate level of landscaping, significantly affect the microclimate of residential buildings. In addition, open buildings are deprived of the individuality of the yard space, so the reconstruction of the neighborhood should be based on the principles of closed or semi-closed buildings. This can be achieved by adding or constructing additional volumes that connect individual buildings. This achieves both economic and functional efficiency of space use.
ARCHITECTURE OF THE RAILWAY STATIONS HOLOBY AND KOVEL IN THE WORK OF O. M. VERBYTSKYI
Authors: Nazaruk Mykola
Published: May 2021

Annotation text. Architecture of the late XIX – early ХХ century causes great interest in researchers. At this time, railways and railway stations were actively built all over the world. At this time also, a new architectural style, called Art Nouveau, has distributed around the world. The representative of this style in Ukraine is the architect O. M. Verbytskyi, whose work is largely reflected in the architecture of railway station complexes.

Today, the question arises of restoring the original appearance of historic architectural objects, including railway stations. Therefore, the research of  history railway, and also the research of town-planning, planning, volume-spatial structure and stylistics of the railway station complexes as a type of buildings are relevant in the framework of historical and architectural researches of Volhynia in the second half of XIX – early ХХ century.

The research methodology is based on general (observation, comparative analysis, etc.), interdisciplinary (structuring, classification, etc.) and disciplinary, that inlude architectural and town-planning (analysis of the urban situation, functional structure and morphology of individual buildings and their complexes) research methods.

Holoby and Kovel railway stations are original and exquisite buildings by their architecture.

The volume-spatial solutions of the Holoby and Kovel railway stations are characterized by the following features: innovation, architectural expressiveness, boldness of compositional solutions, combination of curvilinear forms with rectilinear ones, Art Nouveau style.

The article deals with the history of creation, planning structure, volume-spatial composition and stylistics of the railway stations Holoby and Kovel, which are designed by the outstanding Ukrainian architect O. M. Verbytskyi and built in the beginning of the ХХ century.
TRADITIONAL RESIDENTIAL ARCHITECTURE OF BOYKO CONSTRUCTION SCHOOL ON THE BASIS OF AN ARCHAIC PLAN: PRINCIPLES OF FORMATION
Authors: Parkhuts Liubomyr
Published: May 2021

The article identifies the main patterns of construction of Boyko residential buildings, which are based on an archaic three-part plan. It was found that Boyko's three-chamber dwellings existed in three variants, where the oldest type is considered to be one in which the dwelling cage is located in the middle, and the hayloft and pantry - on the sides of the dwelling. Based on measurements of existing buildings, analysis of literature and archival drawings, an ideal model of traditional three-chamber Boyko housing was created and it was substantiated that the idea of an archaic three-chamber house was based on the laws of the golden section. However, in practice, most houses had minor deviations from this rule, which were due to the different width of the ancillary premises and the violation of the proportions of the living space. The construction of traditional residential buildings of the Boyko construction school meets four basic rules: symmetry or the desire for symmetry in the construction of plans and facades with a possible asymmetrical arrangement of individual elements and parts of the house; staticity of the whole volume of the building; balance of the main elements of the house; variety in the use of details and decor. Despite the typical plans and ancient rules of the general compositional construction of houses, the masters sought uniqueness and artistic expression with the help of details. The location of the yards was influenced by the terrain and local natural conditions. It is revealed that the identity of architectural and natural forms is the main principle that makes it possible to harmoniously link static architectural forms with constantly changing natural. The predominance of the sloping lines of the silhouette of the house over the vertical lines provided an organic connection with the environment.

Published: May 2021

This study was aimed at producing a porous layered glass ceramic material with a decorative-protective coating via one-stage firing. Waste products were used as gas-forming agents to fabricate a glass ceramic material, which partially solves a problem of their utilization; available natural raw materials were also used as gas-forming agents. A decorative-protective coating was applied simultaneously with the formation of the main layers of the material. It consisted of glass cullet and various amounts of coloring oxide. Firing of the samples was carried out at the temperature of 7500С. The coating containing 99.9 wt.% of glass cullet and 0.1 wt.% of Cr2O3 with the thickness of 425 m and having a greenish color was stated to be the coating of the highest quality. As a result of the research, a three-layer porous glass ceramic material was obtained with a low coefficient of thermal conductivity (0.056 W m–1 K–1). The presence of a fourth front decorative-protective layer will allow using this material in construction as a heat-insulating and structural material without additional cladding.

The anticorrosion environmentally friendly pigments based on synthetic zeolite and zinc and calcium phosphates were prepared by mechanochemical method. The surface morphology and chemical composition of the obtained pigments were determined by scanning electron microscopy and energy-dispersive X-ray spectroscopy, respectively. It was established that the modification of zeolite by phosphates of divalent metals causes a decrease in the particle size and an increase in the specific surface area of the obtained composite pigments. It was shown that the use of zeolite/phosphate pigments increases the corrosion resistance of the aluminium alloy in 0.1% aqueous NaCl solution. The addition of complex zeolite/phosphate pigments to the sodium chloride solution decelerates the anodic process of electrochemical corrosion, which indicates the formation of a protective film on the metal surface. The composite pigment zeolite/Zn(H2PO4)2 exhibited the highest anticorrosive effect. A gradual release of the inhibitory components from these environmentally friendly pigments provides their long-term action to protect metal products.

In order to improve the adhesive and physical-mechanical properties of epoxy-thiocol compositions cured without heat treatment, we propose to carry out the reaction of interaction between thiokol mercaptan groups and oxirane cycles of epoxy resin at an elevated temperature before introducing a curing agent, and then use the product of this thioetherification reaction for curing at room temperature. The temperature range of the thioetherification reaction (90–1800С) was determined by the method of differential scanning calorimetry. The optimal temperature (1600С) and duration of the preliminary thioetherification reaction (2 hours) were determined, which ensure the maximum level of adhesive strength and physical-mechanical properties. It was shown that composite materials based on the products of the thioetherification reaction significantly outperform analogs based on mechanical mixtures of epoxy resin and thiokol in terms of cohesive and adhesive strength, deformation capacity, fracture work and specific impact strength. The impact resistance and shear strength of adhesive joints are especially significantly increased during the curing of the compositions without external heat supply.

This work is devoted to the development and study of the processes of accelerated structuring of polymer composite materials in the field of high-frequency current (microwave field) which are used in the electronic and instrument-making industries, etc. The complex of properties and the features of structuring of epoxy, acrylic and epoxy acrylic polymer composite materials in the microwave field are investigated. In comparison with the traditional method of structuring and polymerization (convection heating), the structuring in the microwave field equally affects the properties of the studied polymer composite materials, regardless of the chemical nature of the oligomer. The action of the microwave field for all studied polymer composite materials causes an increase in the degree of conversion of binders and a decrease in the content of residual monomer (methyl methacrylate) in thermoplastic acrylic polymer composite materials. In addition, the microwave treatment provides the completeness of chemical and physicochemical processes of the formation of rational structure of polymer composite materials with stable properties. The conducted research allows recommending various regimes of the structuring of the studied polymer composite materials taking into account operating conditions. These regimes ensure the reduction of structuring duration and provide a high level of mechanical and operational properties.

Published: May 2021

Hydrogels of sequential Ti-containing interpenetrating polymer networks based on hydrophilic cross-linked polyurethanes with different molecular weight of polyethylene glycols and Ti-containing copolymer were synthesized based on 2-hydroxyethyl methacrylate and titanium isopropoxide. The composition of sequential interpenetrating polymer networks was determined by the degree of equilibrium swelling of the polyurethane networks in 2-hydroxyethyl methacrylate and Ti-containing comonomer. It was established that the content of the second component of the interpenetrating polymer networks increases with increasing the average molecular weight value of the polyurethane network. It was shown that the obtained highly sensitive hydrogels of Ti-containing interpenetrating polymer networks react to the changes in the temperature and pH. These factors significantly change the equilibrium water content in the hydrogels. Differential scanning calorimetry allowed determining the phase transitions that are characteristic of bound and free water, which is a part of the hydrogel of polyurethanes, interpenetrating polymer networks and Ti-containing interpenetrating polymer networks. The results showed that the content of bound water and the degree of its binding to the components of the interpenetrating polymer networks depend on the chemical structure of the network, the nature of a second polymer component (which is a part of the interpenetrating polymer networks), the polarity and hydrophilicity of macromolecules, and the size of hydrogel cells. Regardless of the nature of the second polymer component, there is a general trend for all interpenetrating polymer networks: the total water content increases with increasing the average molecular weight of the polyurethane matrix networks.

Published: May 2021

In order to synthesize procaine analogs containing one or two pentafluoroethoxy groups, a method for the synthesis of benzoic acids containing a pentafluoroethoxy group in the ortho-position of the benzene nucleus has been developed. An effective method for the synthesis of procaine structural analogues containing one or two pentafluoroethoxy groups has been proposed. It has been shown that the replacement of the amino group by the pentafluoroethoxy group in the procaine molecule leads to a significant increase in the local anesthetic activity of the obtained compounds. The most active compound was a structural analogue of procainamide containing two pentafluoroethoxy groups in positions 2 and 4. The formation of fluorine-containing analogues of procaine was confirmed by 1H, 19F and 13C NMR spectroscopy and mass spectrometry.

Hematological, immunological and histological changes in guinea pigs in the treatment of microsporia with drugs “Micromar” and “Biogluk”
Authors: Martyniv Y. V. , Kisera Ya. V.
Published: May 2021

Microsporia is a common infectious disease in the practice of a veterinarian. This disease carries a risk of human infection because it is anthropozoonotic. The main pathogen Microsporum sanis affects the upper layers of the skin and has the ability to stay on the body of an animal for up to two years. Therefore, treatment should be carried out by a complex method and be aimed at preventing the spread of the pathogen in the environment and increase the body's resistance in the fight against the disease. “Micromar” based on clotrimazole and povidone iodine and the immunostimulant “Biogluc” based on beta glucan and biotin were used to treat patients with microsporia. Clotrimazole and povidone iodine have antifungal and antiseptic properties, and beta glucan in combination with biotin stimulates the immune response and accelerates the regeneration of damaged skin. In order to determine the immune reactivity of the organism in the treatment of microsporia, hematological, immunological blood tests and histological examinations of the skin of guinea pigs infected with the pathogen M. canis were performed. The obtained results showed that when using the antifungal drug “Micromar” and immunostimulant “Biogluk” the number of leukocytes decreases from 11.13 ± 0.72 to 6.95 ± 0.10 109/L, rod-shaped neutrophils from 16.00 ± 1.29 to 6.17 ± 0.65 %, ESR from 5.67 ± 0.67 to 2.17 ± 0.31 mm/h, and the number of segmental neutrophils increases from 12.17 ± 1.47 to 22.00 ± 0, 86 %. There is a tendency to increase T-helpers. These changes indicate the development of an active immune response to the inflammatory process. In the structure of the skin there is a decrease in exudation and infiltration in the dermis, active trophism of hair follicles, which indicates the course of regenerative processes.

Authors: Montes de Oca-Flores Eric , Cruz-Flores Maryan A. , Espinoza-Ortega Angélica
Published: May 2021

Objective: To evaluate the changes in the main microorganisms groups and the physicochemical properties of Queso Molido (Ground Cheese) from the Central Mexican Highlands, during a 90 days maturation period.
Methodology: The fat, protein, moisture, ash and chloride contents, acidity and pH were analyzed. Microbiological analyzes of total coliforms, lactic acid bacteria, yeasts and Staphylococcus were also assessed. An ANOVA and a principal component analysis were performed to analyze the effect maturation had on the physicochemical and microbiological characteristics.
Results: Both the physicochemical and microbiological parameters showed significant differences (p < 0.05) during the evaluated maturation period. The protein concentration increased, fat and acidity at the end of maturation, along with the absence of coliform bacteria, a decrease in lactic acid bacteria (LAB) and a high concentration of Staphylococcus and yeasts.
Limitations: It is necessary to evaluate these variables in other locations and similar production systems in other latitudes of the country.
Conclusion: The maturation of Queso Molido does not improve its microbiological quality.

The study was descriptive and accounted for 51 producers and thoseresponsible for the cocoa profit centers. Producers were chosen through targetedsampling. A survey on their harvest and postharvest was applied, in addition todirect assessment in plantations and profit centers.Results: The cocoa harvesting is manual. The producers cut the ripe and almostripe fruits, do not store and 58.8% of them do not break the fruit. With a “machete”cut the fruit in half and manually extract the grains. The fresh grains are sold at aprofit. The cocoa is then fermented in wooden boxes, dried artificially, natural, or ina combined way, and packed in “yute” bags for sale. Profit centers do not keeptrack of their grain origin and make no selection or determine product quality.
Study limitations / implications: All producers harvest in the same way, but theprocesses during post-harvest could differ at different collection centers.Findings / conclusions: The harvest of cocoa fruits at different maturity and thelack of storage causes a heterogeneous fermentation. The humidity level duringthe drying process is empirically determined.

Authors: Reis Francisco Cavalcanti
Published: May 2021

O presente artigo busca identificar como os estudantes do curso de Administração que atuaram em Empresas Juniores percebem as experiências e vivências neste tipo de organização como fatores de formação e qualificação profissional, preparando-os para a inserção em um cenário marcado pelo desemprego e alto nível de competitividade. Para isso, utilizou-se uma metodologia quantitativa descritiva, com a aplicação de um questionário estruturado para 103 estudantes de Administração que participaram de uma Empresa Junior durante a graduação. Por meio da análise dos resultados, embasada no referencial teórico elaborado, foi possível constatar que a Empresa Junior aparece como alternativa eficaz para suprir as carências do ensino identificadas nas universidades, as quais apesar de terem sido consideradas importantes para a formação e qualificação profissional, apresentam deficiências quanto ao ensino prático e com divergências entre os setores de atuação para os quais elas preparam seus empresários juniores e os setores onde eles desejam exercer sua profissão. Avaliou-se que por meio das vivências e experiências adquiridas na Empresa Junior, é oportunizado ao aluno o desenvolvimento de competências e habilidades desejáveis para um Administrador que não estariam contempladas no ensino oferecido nas salas de aula da graduação, além de possibilitar o delineamento de um plano de carreia inicial.

Sobre orgulho, vergonha e superação: o impacto da corrupção na dotação de sentido ao trabalho entre os funcionários da Petrobras
Authors: Souza Daniel Oswaldo Santana de
Published: May 2021

Nos últimos dois anos o Brasil vê o desenrolar de uma operação policial que atingiu em cheio a principal empresa estatal do país. Chamada de “Lava Jato”, as investigações capitaneadas pela Polícia Federal tinham como objetivo inicial desbaratar esquemas de lavagem de dinheiro envolvendo lobistas, empresários e políticos brasileiros. Não levou muito tempo até que as investigações chegassem à Petrobrás, onde foram denunciadas diversas ações fraudulentas de pagamento de propinas através de empresas fantasmas, “laranjas”, visando ao financiamento de campanhas políticas, acordos de favorecimento e enriquecimento ilícito de seus agentes. Neste cenário específico, os aspectos subjetivos relacionados ao trabalho dos funcionários da Petrobrás merecem atenção. Pesquisas acerca do significado do trabalho multiplicam-se no meio acadêmico, reforçando a relevância que a dotação de sentido à atividade profissional tem tanto no desempenho dos funcionários, como no das organizações como um todo (ROSSO, DEKAS e WRZESNIEWSKI, 2010). Esta pesquisa, através de entrevistas em profundidade com empregados da estatal, investigou o impacto da percepção da corrupção no significado do trabalho, de acordo com a definição tridimensional do modelo teórico proposto pelo MOW (1987). Pelas declarações coletadas, percebe-se que a segunda dimensão do construto - a que trata das normas sociais, sobre direitos e deveres relacionados ao trabalho do indivíduo para com a empresa e a sociedade – foi a mais impactada, principalmente no que se refere aos deveres dos profissionais para com a empresa e a sociedade. As outras dimensões – centralidade e objetivos e resultados valorizados do trabalho – foram influenciadas em menor grau.

Several important observations regarding performance scaling effect of Aero-Naut folding propellers and its impact on performance optimization are discussed. The resulting optimized propeller selections are proposed which would enhance mission capability of CREATeV. Finally, future work considerations and concluding remarks of the analysis is presented.
Brothers in the kitchen: the uprising, exodus and survival of a Tamil minority
Authors: Sundar Singh Cyrus
Published: May 2021

Brothers In the Kitchen (BiTk), is a site-specific live-documentary performed with an audience inside a fully operational restaurant. The triumvirate of story, performance, and audience is used to create an interactive and immersive documentary experience incorporating oral storytelling, poetry, dance, music, archival materials and television— all performed live. BiTk is the story of the uprising, exodus and survival of Tamil Sri Lankan citizens who fled a brutal civil war and sought refuge in Canada. The ethnic conflict, between the Buddhist Sinhala majority and the Hindu Tamil minority, sparked a mass exodus following the deadly riots of Black July in 1983. Subsequently, a staggering 300,000 Tamils found asylum in Canada. Soon an inordinate number of them began work as cooks and dishwashers in many Canadian restaurants. This live documentary is performed thirty years after the arrival of the first boatload of Tamil refugees, found adrift off the coast of Newfoundland, in 1986.

The equations were combined and placed into the form of a linearized state-space equation. The different control methods being investigated, Linear Quadratic Regulator (LQR) for the reaction wheel model, and the Bdot with bias controller, were explained and the block diagram for each was shown. To setup the test, the tolerances for the roll, pitch, and yaw, and their rates, were taken from the mission requirement for the ESSENCE mission. The attitude tolerance being ±0.5deg and the angular rates requirement being ±0.05deg/s. Then the test setup was further explained. The test is broken up into different scripts and steps:
1. Main run function for simulation. Initializes simulation parameters.
2. Build state-space equation and calculate constant gain matrix.
3. Randomize initial conditions and pass onto simulation.
4. Post-processing and plot generation.
5. Statistics generation.
This robust testing environment was used to test 5 different controllers for the reaction wheel model. Each controller was tested for 200 different simulations, in which the initial attitude, initial angular rates, and the center of mass were randomized. The first controller was successful for 198/200 simulations, where the only failure came from over-saturating the reaction wheels. The next three controllers had a perfect record and were successful for all 200 simulations each. The last controller, had only 71 successful simulations in the set, and a sample of one of the failed simulations was further investigated to see how it failed.
Investigation of Falcon Dive and Developing Kinematic Approach
Authors: Mulla Aadil
Published: May 2021

This study investigates the aerodynamic methods already implemented in studying a peregrine falcon dive. The paper presents a literature review of aerodynamic methods, starting from mathematical models aimed at predicting falcon dive using minimum drag theory. This is followed by experimental methods that developed the flight path trajectory using high-tech cameras. Additionally, the paper presents numerical analysis of the falcon body model using computational fluid dynamics and particle image velocimetry in order to assess and derive aerodynamic coefficients. Based on the research, a kinematic model for the problem was developed, and the reason for failure were highlighted.
Indigenous city fieldtrip : A resource guide to Ryerson University
Authors: Caribou Jeremie , Reesor Rachel
Published: May 2021

This resource guide contributes to a knowledge base of events, facts, interpretations, and relationships relating to Indigenous peoples with a particular focus on the land that is currently occupied by Ryerson University. This knowledge base is available for free to anyone who wishes to learn about or educate others about this topic. We realize that nobody “owns” this knowledge but that knowledge is always embodied and situated in personal experiences. Please use and share this knowledge responsibly and with respect.

The guide is intended to facilitate walking field trips involving particular sites (i.e. “stations”) located on or close to Ryerson campus. For each station, we identified several resources and included links to original sources. We structured this guide by listing the sources followed by a brief description of the information from the source in bullet form. This brief description does not replace reading the original source but is rather intended to help the reader navigate the guide.

We envision several ways in which this guide can be used: it can be used as a self-guided tour; it can be used by the community organizations and Ryerson instructors to develop field trips to be delivered to their classes or other audiences; or it can be used by students and the wider community to learn about Indigenous peoples and their relationship to Ryerson University.
Development of CT texture analysis in COPD and association with visual scoring and DLco
Authors: Lui Victor , Tan W. C. , Hogg J. C. , Coxson H. O. , Kirby Miranda
Published: May 2021

  

Objectives

To determine if CT texture features, such as GLCM and FD, can differentiate patients with COPD from healthy volunteers, and are related to lung function

To determine if CT texture features are association with qualitative visual scoring

To determine if CT texture features are significantly associated with COPD outcomes, independent of qualitative scoring and standard quantitative CT emphysema measurements

Hypothesis

CT texture features can be developed to objectively aid in quantifying the severity of emphysema, and may provide information complementary to qualitative visual assessment
Analytical and experimental solution for heat source located under skin: chest tumor detection via IR camera
Authors: Rastgar-Jazi Maryam
Published: May 2021

Infrared (IR) imaging could be used as both noninvasive and nonionizing technology. Utilizing
IR camera, it is possible to measure skin temperature with the aim of finding any superficial
tumors. Since tumors are highly vascular and usually have a higher temperature than the rest of
the body, using thermograms, it is possible to assess various tumor parameters, such as depth,
intensity, and radius. In this study, we have developed an analytical method to detect tumor
parameters in both spherical and cubical tissues to represent female breast and male chest tissue.
This includes development of analytical solution for solving inverse bio-heat problem as well as
laboratory set up for further validation of the analytical achievements. The models were
developed by solving Penne’s Bioheat equation for each tissue under certain conditions and two
main assumptions:
1. The tumor was assumed as separate heat source;
2. The developed model does not change with time (steady state condition).

Finally, the analytical findings were validated by utilizing a laboratory test set-up containing an
IR camera, 1% Agar solution (tissue phantom), and a heater of variable powers. The models
were set to test by adjusting the heater (0.9W) in various depth and imaging the tissue phantom.
Comparing the analytically obtained results with the experimental results, it can be concluded
that the method is able to detect superficial tumors of small size only by measuring the body
surface temperature and ambient temperature.
“If you are in Palermo, you are a Palermitan": An Interview with Mayor Leoluca Orlando
Authors: Bauder Harald
Published: May 2021

Leoluca Orlando was born in 1947 in the Sicilian city of Palermo. After studying in Heidelberg, Germany, and Palermo, he worked as a professor of public law at the University of Palermo. In 1985, Palermo’s city council elected Orlando for the first time as Mayor. Currently, he serves his fifth term. In between, he also had seats in the European and the Italian Parliaments, and he served as opposition leader in the Sicilian Parliament. In his first term as Mayor, he took up the fight against the Sicilian mafia; today he fights against racism and the restrictive migration policies of Italy’s national government and the European Union.
Spatial Dimensions of Multi-Criteria Analysis
Authors: Rinner Claus
Published: May 2021

Multi-criteria decision making (MCDM) has been introduced to GIS about 15 years ago. Decision rules that have been implemented in the GIS environment include weighted linear combination, analytical hierarchy process, ideal point analysis, concordance-discordance analysis, and ordered weighted averaging. The spatial dimensions of MCDM include spatially distributed decision-makers and decision alternatives, decision objectives relating to geographical objects, and a non-uniform weighting across space. However, few (if any) MCDM methods incorporate spatial relationships in the decision rule itself. This presentation suggests using geographical weighting to influence the calculation of aggregated suitability scores. Inverse distance-based weights are used to adapt the suitability of locations to their neighbours’ scores. This method was implemented in the thematic mapping package CommonGIS, and applied to a site selection problem to demonstrate the usefulness of geographically weighted MCDM. Through its interactive cartography, CommonGIS supports the application of geographical weighting in conjunction with other spatial dimensions of multi-criteria analysis.
Corporate social responsibility in the Canadian context: the new role of corporations in community involvement and social issues
Authors: Foster Mary K. , Meinhard Agnes B.
Published: May 2021

[First paragraph of Introduction]: The rapidly growing literature investigating corporate social responsibility (CSR) attests to the world-wide interest in this trend, both from an academic perspective and as a legitimate component of commercial success (Burson-Marsteller, 2000; Waddock & Graves, 1997). To date, most of the research has been conducted in the US, and indeed research interest in this topic dates back to the 1930s and 1940s (Carroll, 1999). The body of knowledge about CSR in Canada is more modest and has mostly focused on investigating social disclosure from an accounting perspective (Levin, 1982; Zeghal & Ahmed, 1990). One reason for this narrow focus has been historical. Unlike in the US, the Canadian government has been the primary architect, builder and funder of the social safety net. Until very recently, this dominant role of government has preempted the need for widespread corporate participation in the provision of social services. Thus tracking the nature and scope of CSR activities in the private sector has not been a major area of interest for Canadian researchers. Indeed, as recently as the 1980s, much of the CSR focus in Annual Reports of Canadian companies was on internal human resource issues such as employee health, safety and training, and not on community and social service issues (Zeghal & Ahmed, 1990).

Future-proof: preparing young Canadians for the future of work
Authors: Lamb Creig , Doyle Sarah
Published: May 2021

There are a number of major trends that have the potential to shape the future of work, from climate change and
resource scarcity to demographic shifts resulting from an aging population and immigration. This report focuses on the need to prepare Canada’s youth for a future where a great number of jobs will be rapidly created, altered or made obsolete by technology.

Successive waves of technological advancements have rocked global economies for centuries, reconfiguring the labour force and giving rise to new economic opportunities with each wave. Modern advances, including artificial intelligence and robotics, once again have the potential to transform the economy, perhaps more rapidly and more dramatically than ever before. As past pillars of Canada’s economic growth become less reliable, harnessing technology and innovation will become increasingly important in driving productivity and growth.
“No Apple iPhone? You must be Canadian”: mobile technologies, participatory culture, and rhetorical transformation
Authors: Pedersen Isabel
Published: May 2021

Abstract: Participation with new mobile devices drives new social practices. This article engages in a close analysis of a so-called participatory culture surrounding iPods and iPhones. It offers close rhetorical readings of object phenomena including advertisements, Canadian news stories, and consumer reactions in electronic media. More specifically, this article reveals a rhetorical transformation between the iPod Silhouettes advertising campaign and the iPhone release campaign, causing a shift in subjectivity; iPod subjects are afforded a degree of freedom and play, while iPhone subjects are bound to regimes of work. It is also argued that news stories that emerged in the summer of 2007, when the iPhone was not released in Canada, structure a rhetoric of the “excluded Canadian.”
