Collaboration between Librarians and Teaching Faculty to Teach Information Literacy at one Ontario University: Experiences and Outcomes
Authors: Reed Maureen J. , Kinder Don , Farnum Cecile
Published: July 2021

Purpose: In this study, we sought to describe information literacy success outcomes for students who participated in a university course where university librarians and teaching faculty collaborated in all aspects of the course including; curricular development, assignment development, in-class teaching, office hours for individual student development, and assessment activities. The authors wanted to examine student success in attaining information literacy skills following this one semester course. Further, the authors wanted to determine what difficulties in achieving expected information literacy levels persist even after intensive collaborative instruction. Finally, the authors wished to describe the challenges of these collaborations.

Methodology: The focus of this study was to determine changes in first-year university students’ information literacy knowledge and skill following a thirteen week university preparation course that was developed through strong collaboration between university librarians and teaching faculty. Students entering their first semester of university were tested on their information literacy skills without feedback. They then took part in the required course and were post tested in the last week of the semester.

Findings: Student showed strong increases in information literacy from this collaborative approach. In addition, teaching faculty and librarians felt positive about the collaborative experience. However, some students showed misunderstandings about information literacy that requires further research.

Originality and Practical Implications: Our unique contribution here is our description, experiences and detailed outcomes with a collaborative process to teach information literacy. Based on our experiences here, we believe that collaboration will work best if it is planned at a curricular level, if the librarians are truly integrated into the classroom, if the librarians provide input on assignments and help with student feedback, and if targeted information literacy knowledge is tested. This planning takes time, but the librarians offer unique contributions and insight into issues surrounding information literacy that may not be obvious to faculty instructors. In our study, we also found that students confuse assignment requirements with general information literacy standards and those teaching information literacy need to be aware of these confusions. Finally, integration of librarians into college/university courses has benefits in terms of increases in student information literacy and increases in librarian knowledge of faculty expectations.

Published: July 2021

With global concern for climate change, and for cutting down the energy cost, especially in off grid areas, use of renewable energy has been gaining widespread attention in many areas including cellular communication. The base station (BS) has emerged as a strong candidate for the integration of renewable energy sources (RES), particularly solar and wind. The incorporation of renewable energy opens many possibilities for energy conservation through strategies such as energy cooperation between BSs during the off-peak hours, when the energy harvested from renewable energy sources may become surplus. In this paper, we present the case for cellular BSs enabled with renewable energy sources (RES) to have an arrangement in which the BS provide surplus energy to a neighboring BS, thus minimizing the use of conventional energy. A realistic objective is developed for northern region of Pakistan, which entails modeling of solar panels and wind-turbine according to the average solar irradiation and wind speed of the region. We also model the dynamic load of the BS, which depicts temporal fluctuations with traffic variations. Based on these models we initiate an energy cooperation scheme between the BS in which an energy cost minimization framework is mathematically modeled and solved through the interior point method algorithm. Results are obtained for different times of the year for different number of base stations showing respective energy cost savings.

Personalized Multi-Criteria Decision Strategies in Location-based Decision Support
Authors: Rinner Claus , Raubal Martin
Published: July 2021

Location-based services (LBS) assist people in decision-making during the performance of tasks in space and time. Current LBS support spatial and attribute queries, such as finding the nearest Italian restaurant from the current location of the user, but they are limited in their capacity to evaluate decision alternatives and to consider individual decision-makers’ user preferences. We suggest that LBS should provide personalized spatial decision support to their users. In a prototype implementation, we demonstrate how user preferences can be translated into parameters of a multi-criteria evaluation method. In particular, the Ordered Weighted Averaging (OWA) operator allows users to specify a personal decision strategy. A traveler scenario investigating the influence of different types of users and different decision strategies on the outcome of the analysis serves as a case study.
A Techno-economic Analysis of Heat-Pump Entering Fluid Temperatures, and CO2 Emissions for Hybrid Ground Source Heat Pump Systems

Published: July 2021

Hybrid ground-source heat pumps (GSHPs) that include a ground loop for the base heating and cooling needs, and an auxiliary system (natural gas boiler and electric air conditioner) for peak loads, are an economical and environmentally cleaner alternative to conventional systems. For a ground-source heat pump (GSHP) system, the choice of entering fluid temperature (EFT) to the heat pump plays a crucial role in determining system efficiency of and operating costs. To continue expanding the knowledge base of efficiently sizing GSHPs as a component of a hybrid system, this study explores the economic effects of choosing an EFT for a heat pump. In addition, system CO2 emissions are calculated and analyzed for a variety of building types. Using a computational approach to size hybrid GSHP systems recently published in [Alavy et al., Renewable Energy, 57 (2013) 404-412], the effects of optimizing EFT for a heat pump, and CO2 emissions were studied for a variety of commercial installations. In the present study, using ten buildings situated in Southern Ontario, Canada, by varying cooling and heating EFTs for a heat pump, savings ranging from 0.47% to 3.6% can be achieved compared to using a fixed EFT pairfor a heat pump. In addition, comparisons were made between the CO2 emissions of optimally sized (based on economic factors) hybrid GHSPs and those of non-hybridized GSHPs. Both the optimally-sized hybrid GHSPs, and the non-hybridized GSHPs significantly reduce CO2 emissions compared to the use of conventional natural gas/electrical systems. The additional environmental benefit of the non-hybridized GSHPs over that of the optimally-sized hybrid GSHPs was found to be negligible in most cases analyzed.

Published: July 2021

The hydrolysis in lysosomes of GM2 ganglioside to GM3 ganglioside requires the correct synthesis, intracellular assembly and transport of three separate gene products; i.e., the alpha and beta subunits of heterodimeric beta-hexosaminidase A, E.C. # 3.2.1.52 (encoded by the HEXA and HEXB genes, respectively), and the GM2-activator protein (GM2AP, encoded by the GM2A gene). Mutations in any one of these genes can result in one of three neurodegenerative diseases collectively known as GM2 gangliosidosis (HEXA, Tay-Sachs disease, MIM # 272800; HEXB, Sandhoff disease, MIM # 268800; and GM2A, AB-variant form, MIM # 272750). Elements of both of the hexosaminidase A subunits are needed to productively interact with the GM2 ganglioside-GM2AP complex in the lysosome. Some of these elements have been predicted from the crystal structures of hexosaminidase and the activator. Recently a hybrid of the two subunits has been constructed and reported to be capable of forming homodimers that can perform this reaction in vivo, which could greatly simplify vector-mediated gene transfer approaches for Tay-Sachs or Sandhoff diseases. A cDNA encoding a hybrid hexosaminidase subunit capable of dimerizing and hydrolyzing GM2 ganglioside could be incorporated into a single vector, whereas packaging both subunits of hexosaminidase A into vectors, such as adeno-associated virus, would be impractical due to size constraints. In this report we examine the previously published hybrid construct (H1) and a new more extensive hybrid (H2), with our documented in cellulo (live cell- based) assay utilizing a fluorescent GM2 ganglioside derivative. Unfortunately when Tay-Sachs cells were transfected with either the H1 or H2 hybrid construct and then were fed the GM2 derivative, no significant increase in its turnover was detected. In vitro assays with the isolated H1 or H2 homodimers confirmed that neither was capable of human GM2AP-dependent hydrolysis of GM2 ganglioside.
Review of Cognitive Behavioural Therapy Mobile Apps Using a Reference Architecture embedded in the Patient-Provider Relationship
Authors: Lan Alice , Lee Alexandra , Munroe Kristin , McRae Cameron , Kaleis Linda , Keshavjee Karim , Guergachi Aziz
Published: July 2021

Background: Mobile health apps (mHealth apps) are increasing in popularity and utility for the management of many chronic diseases. Although the current reimbursement structure for mHealth apps is lagging behind the rapidly improving functionality, more clinicians will begin to recommend these apps as they prove their clinical worth. Payors such as the government or private insurance companies will start to reimburse for the use of these technologies, especially if they add value to patients by providing timely support, a more streamlined patient experience, and greater patient convenience. Payors are likely to see benefits for providers, as these apps could help increase productivity between in-office encounters without having to resort to expensive in-person visits when patients are having trouble managing their disease.

Key findings
To guide and perhaps speed up adoption of mHealth apps by patients and providers, analysis and evaluation of existing apps needs to be carried out and more feedback must be provided to app developers. In this paper, an evaluation of 35 mHealth apps claiming to provide cognitive behavioural therapy was conducted to assess the quality of the patient-provider relationship and evidence-based practices embedded in these apps. The mean score across the apps was 4.9 out of 20 functional criteria all of which were identified as important to the patient-provider relationship. The median score was 5 out of these 20 functional criteria.

Conclusion
Overall, the apps reviewed were mostly stand-alone apps that do not enhance the patient-provider relationship, improve patient accountability or help providers support patients more effectively between visits. Large improvements in patient experience and provider productivity can be made through enhanced integration of mHealth apps into the healthcare system.
Care and the self: biotechnology, reproduction, and the good life
Authors: Murray Stuart J
Published: July 2021

This paper explores a novel philosophy of ethical care in the face of burgeoning biomedical technologies. I respond to a serious challenge facing traditional bioethics with its roots in analytic philosophy. The hallmarks of these traditional approaches are reason and autonomy, founded on a belief in the liberal humanist subject. In recent years, however, there have been mounting challenges to this view of human subjectivity, emerging from poststructuralist critiques, such as Michel Foucault's, but increasingly also as a result of advances in biotechnology itself. In the face of these developments, I argue that the theoretical relevance and practical application of mainstream bioethics is increasingly under strain. Traditionalists will undoubtedly resist. Together, professional philosopher-bioethicists, public health policymakers, and the global commercial healthcare industry tend to respond conservatively by shoring up the liberal humanist subject as the foundation for medical ethics and consumer decision-making, appealing to the familiar tropes of reason, autonomy, and freedom.

I argue for a different approach to bioethics, and work towards a new way to conceive of ethical relations in healthcare – one that does not presume a sovereign subject as the basis of dignity, personhood or democracy. Instead, I am critical of the narrow instantiations of reason, autonomy, and freedom, which, more recently, have been co-opted by a troubling neo-liberal politics of the self. Thus, I am critical of current trends in medical ethics, often running in tandem with corporate-governmental models of efficiency, accountability, and so-called evidence-based best practices. As an example of such market-driven conceptions of subjectivity, I discuss the paradigm of "self-care." Self-care shores up the traditional view of the self as a free agent. In this sense, self-care is looked upon favourably by mainstream bioethics in its focus on autonomy, while healthcare policy endorses this model for ideological and economic reasons. To contrast this, I propose a different model of care together with a different model of selfhood. Here I develop and apply Foucault's late work on the "care of the self." In this understanding of "care," I suggest that we might work towards an ethical self that is more commensurable both with recent theoretical views on subjectivity and – more pressingly – with the challenges of emergent biotechnologies. I end this paper with a discussion on ethical parenthood, which offers a practical reading of the "care of the self" in relation to new reproductive technologies (NRTs).
Exploring Cell Tropism as a Possible Contributor to Influenza Infection Severity
Authors: Beauchemin Catherine A. A. , Dobrovolny Hana M. , Baron Marc J. , Gieschke Ronald , Davies Brian E. , Jumbe Nelson L.
Published: July 2021

Several mechanisms have been proposed to account for the marked increase in severity of human infections with avian compared to human influenza strains, including increased cytokine expression, poor immune response, and differences in target cell receptor affinity. Here, the potential effect of target cell tropism on disease severity is studied using a mathematical model for in-host influenza viral infection in a cell population consisting of two different cell types. The two cell types differ only in their susceptibility to infection and rate of virus production. We show the existence of a parameter regime which is characterized by high viral loads sustained long after the onset of infection. This finding suggests that differences in cell tropism between influenza strains could be sufficient to cause significant differences in viral titer profiles, similar to those observed in infections with certain strains of influenza A virus. The two target cell mathematical model offers good agreement with experimental data from severe influenza infections, as does the usual, single target cell model albeit with biologically unrealistic parameters. Both models predict that while neuraminidase inhibitors and adamantanes are only effective when administered early to treat an uncomplicated seasonal infection, they can be effective against more severe influenza infections even when administered late.
Facing the music
Authors: Thompson William F , Russo Frank
Published: July 2021

From the phonograph of the 19th century to the iPod today, music technologies have typically isolated the auditory dimension of music, filtering out nonacoustic information and transmitting what most people assume is the essence of music. Yet many esteemed performers over the past century, such as Judy Garland and B.B. King, are renowned for their dramatic use of facial expressions (Thompson, Graham, & Russo, 2005). Are such expressions merely show business, or are they integral to experiencing music?

In the investigation reported here, we considered whether the facial expressions and head movements of singers communicate melodic information that can be “read” by viewers. Three trained vocalists were recorded singing ascending melodic intervals. Subjects saw the visual recordings (without sound) and rated the size of the intervals they imagined the performers were singing
An Application for Regional Coastal Erosion Processes in Urban Areas: A Case Study of the Golden Horseshoe in Canada
Authors: de Noronha Vaz Eric , Bowman Lisa
Published: July 2021

Urban growth has had unprecedented consequences on environmental sustainability and anthropogenic activity. The eroding coastlines throughout the world are subject to the massive expansion of urban areas and the accountability of sustainable hinterland landscapes. The Golden Horseshoe is Canada’s fastest growing region extending from the Niagara Peninsula and one of the most active economic regions in North America. This paper adopts a combined assessment of land use change and transitions in the coastal stretches of the Greater Golden Horseshoe. Comprising the urban expansion of the region between 1990 and 2011, an integrated assessment was carried out to: (i) detect changes in coastal lines along Lake Ontario; (ii) derive land use changes along the coast through spatial accounting matrices; and (iii) integrate climate change data for a combined assessment of future erosion loci. Visible erosion was found between the decade of 1990 and 2000, while certain areas have shown coastal recession in the southern region. The maximum recession was found to be 30 m, with an increasing urban sprawl of 19.8% between 1990 and 2000. A combined temperature increase of 2 °C over the coming decades brings the increase in urban heat islands leading to the importance of combined land policies to mitigate the common problem of erosion in vulnerable urban stretches and liveability concerning spatial resilience of growing urban regions in North America.
Technology-adaptable interventions for treating depression in adults with cognitive impairments: protocol for a systematic review
Authors: Topolovec-Vranic Jane , Mansoor Yasmeen , Ennis Naomi , Lightfoot David
Published: July 2021

Background
Depression is a common comorbidity in individuals with cognitive impairment. Those with cognitive impairments face unique challenges in receiving the benefits of many conventional therapies for depression, and may have poorer outcomes in areas such as recovery and quality of life. However, the stigmatization of mental health disorders, cost barriers and physical disabilities may prevent these individuals from seeking mental health care. An online, self-help intervention specifically developed for adults with cognitive deficits and depression may be particularly beneficial to this population. We aim to inform the design of such an intervention through a systematic review by answering the following research question: among adults with cognitive impairment (including those with acquired brain injuries or neurodegenerative diseases), which technology-amenable interventions have been shown to effectively decrease symptoms of depression? Specifically, psychotherapeutic and/or behavioural interventions that could be delivered in a self-guided, online system will be included.

Methods
Comprehensive electronic searches will be conducted in MEDLINE, EMBASE, PsycINFO and CINAHL. Additional studies will be obtained through manually searching the references of relevant systematic reviews, contacting primary authors of select articles and tracking conference proceedings and trial registries. Article titles and abstracts will be screened using predefined eligibility criteria, and then judged for their amenability to the proposed self-help, technology-based intervention. The full text of those articles with selected interventions will then be screened to determine final eligibility for inclusion. Included articles will be categorized by intervention type and assessed for risk of bias using the Cochrane Effective Practice and Organization of Care Risk of Bias tool for non-randomized trials, controlled before-after studies and interrupted time series. The primary outcome will be a change in score on a validated depression scale, and adverse events will be documented as a secondary outcome. After data extraction from selected articles, pooling of data and meta-analysis will be conducted if a sufficient pool of studies with comparable methodology and quality are identified. Alternatively, plain language summaries will be developed. The quality of evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.
Supported housing programs for persons with serious mental illness in rural northern communities: A mixed method evaluation
Authors: Montgomery Phyllis , Forchuk Cheryl , Duncan Craig , Rose Donald , Bailey Patricia H , Veluri Ramamohan
Published: July 2021

Background: During the past two decades, consumers, providers and policy makers have recognized the role of supported housing intervention for persons diagnosed with serious mental illness (SMI) to be able to live independently in the community. Much of supported housing research to date, however, has been conducted in large urban centers rather than northern and rural communities. Northern conditional and contextual issues such as rural poverty, lack of accessible mental health services, small or non-existing housing markets, lack of a continuum of support or housing services, and in some communities, a poor quality of housing challenge the viability of effective supported housing services. The current research proposal aims to describe and evaluate the processes and outcomes of supported housing programs for persons living with SMI in northern and rural communities from the perspective of clients, their families, and community providers.
Correctional nursing: a study protocol to develop an educational intervention to optimize nursing practice in a unique context
Authors: Almost Joan , Gifford Wendy A , Doran Diane , Ogilvie Linda , Miller Crystal , Rose Donald , Squires Mae
Published: July 2021

Background
Nurses are the primary healthcare providers in correctional facilities. A solid knowledge and expertise that includes the use of research evidence in clinical decision making is needed to optimize nursing practice and promote positive health outcomes within these settings. The institutional emphasis on custodial care within a heavily secured, regulated, and punitive environment presents unique contextual challenges for nursing practice. Subsequently, correctional nurses are not always able to obtain training or ongoing education that is required for broad scopes of practice. The purpose of the proposed study is to develop an educational intervention for correctional nurses to support the provision of evidence-informed care.

Methods
A two-phase mixed methods research design will be used. The setting will be three provincial correctional facilities. Phase one will focus on identifying nurses’ scope of practice and practice needs, describing work environment characteristics that support evidence-informed practice and developing the intervention. Semi-structured interviews will be completed with nurses and nurse managers. To facilitate priorities for the intervention, a Delphi process will be used to rank the learning needs identified by participants. Based on findings, an online intervention will be developed. Phase two will involve evaluating the acceptability and feasibility of the intervention to inform a future experimental design.

Discussion
The context of provincial correctional facilities presents unique challenges for nurses’ provision of care. This study will generate information to address practice and learning needs specific to correctional nurses. Interventions tailored to barriers and supports within specific contexts are important to enable nurses to provide evidence-informed care.
Scale Effects on Quasi-Steady Solid Rocket Internal Ballistic Behaviour
Authors: Greatrix David R.
Published: July 2021

The ability to predict with some accuracy a given solid rocket motor’s performance before undertaking one or several costly experimental test firings is important. On the numerical prediction side, as various component models evolve, their incorporation into an overall internal ballistics simulation program allows for new motor firing simulations to take place, which in turn allows for updated comparisons to experimental firing data. In the present investigation, utilizing an updated simulation program, the focus is on quasi-steady performance analysis and scale effects (influence of motor size). The predicted effects of negative/positive erosive burning and propellant/casing deflection, as tied to motor size, on a reference cylindrical-grain motor’s internal ballistics, are included in this evaluation. Propellant deflection has only a minor influence on the reference motor’s internal ballistics, regardless of motor size. Erosive burning, on the other hand, is distinctly affected by motor scale.
Macro Level Modeling of a Tubular Solid Oxide Fuel Cell
Authors: Suther Torgeir , Fung Alan , Koksal Murat , Zabihian Farshid
Published: July 2021

This paper presents a macro-level model of a solid oxide fuel cell (SOFC) stack implemented in Aspen Plus® for the simulation of SOFC system. The model is 0-dimensional and accepts hydrocarbon fuels such as reformed natural gas, with user inputs of current density, fuel and air composition, flow rates, temperature, pressure, and fuel utilization factor. The model outputs the composition of the exhaust, work produced, heat available for the fuel reformer, and electrochemical properties of SOFC for model validation. It was developed considering the activation, concentration, and ohmic losses to be the main over-potentials within the SOFC, and mathematical expressions for these were chosen based on available studies in the literature. The model also considered the water shift reaction of CO and the methane reforming reaction. The model results were validated using experimental data from Siemens Westinghouse. The results showed that the model could capture the operating pressure and temperature dependency of the SOFC performance successfully in an operating range of 1–15 atm for pressure and 900 °C–1,000 °C for temperature. Furthermore, a sensitivity analysis was performed to identify the model constants and input parameters that impacted the over-potentials.
Modeling the Relationship between the Gross Domestic Product and Built-Up Area Using Remote Sensing and GIS Data: A Case Study of Seven Major Cities in Canada
Authors: Faisal Kamil , Abdelrahman Ahmed , Habbani Suhaib
Published: July 2021

City/regional authorities are responsible for designing and structuring the urban morphology based on the desired land use activities. One of the key concerns regarding urban planning is to establish certain development goals, such as the real gross domestic product (GDP). In Canada, the gross national income (GNI) mainly relies on the mining and manufacturing industries. In order to estimate the impact of city development, this study aims to utilize remote sensing and Geographic Information System (GIS) techniques to assess the relationship between the built-up area and the reported real GDP of seven major cities in Canada. The objectives of the study are: (1) to investigate the use of regression analysis between the built-up area derived from Landsat images and the industrial area extracted from Geographic Information System (GIS) data; and (2) to study the relationship between the built-up area and the socio-economic data (i.e., real GDP, total population and total employment). The experimental data include 42 multi-temporal Landsat TM images and 42 land use GIS vector datasets obtained from year 2005 to 2010 during the summer season (June, July and August) for seven major cities in Canada. The socio-economic data, including the real GDP, the total population and the total employment, are obtained from the Metropolitan Housing Outlook during the same period. Both the Normalized Difference Built-up Index (NDBI) and Normalized Difference Vegetation Index (NDVI) were used to determine the built-up areas. Those high built-up values within the industrial areas were acquired for further analysis. Finally, regression analysis was conducted between the real GDP, the total population, and the total employment with respect to the built-up area. Preliminary findings showed a strong linear relationship (R2= 0.82) between the percentage of built-up area and industrial area within the corresponding city. In addition, a strong linear relationship (R2= 0.8) was found between the built-up area and socio-economic data. Therefore, the study justifies the use of remote sensing and GIS data to model the socio-economic data (i.e., real GDP, total population and total employment). The research findings can contribute to the federal/municipal authorities and act as a generic indicator for targeting a specific real GDP with respect to industrial areas.
Effects of erythrocyte oxygenation on optoacoustic signals
Authors: Saha Ratan K. , Kolios Michael C.
Published: July 2021

A theoretical model examining the effects of erythrocyte oxygenation on optoacoustic (OA) signals is presented. Each erythrocyte is considered as a fluid sphere and its optical absorption is defined by its oxygen saturation state. The OA field generated by a cell is computed by solving the wave equation in the frequency domain with appropriate boundary conditions. The resultant field from many cells is simulated by summing the pressure waves emitted by individual cells. A Monte Carlo algorithm generates 2-D spatially random distributions of oxygenated and deoxygenated erythrocytes. Oxygen saturation levels of oxygenated cells a assumed to be 100% and 0% for deoxygenated cells. The OA signal amplitude decreases monotonically for the 700-nm laser source and increases monotonically for 1000 nm optical radiation when blood oxygen saturation varies from 0 to 100%. An approximately sixfold decrease and fivefold increase of the OA signal amplitude were computed at those wavelengths, respectively. The OA spectral power in the low-frequency range (<10 MHz) and in the very high-frequency range (>100 MHz) decreases for 700 nm and increases for 1000 nm with increasing blood oxygen saturation. This model provides a theoretical framework to study the erythrocyte oxygenation-dependent OA signals.
Run-Time Mitigation of Power Budget Variations and Hardware Faults by Structural Adaptation of FPGA-Based Multi-Modal SoPC
Authors: Sharma Dimple , Kirischian Lev , Kirischian Valeri
Published: July 2021

Systems for application domains like robotics, aerospace, defense, autonomous vehicles, etc. are usually developed on System-on-Programmable Chip (SoPC) platforms, capable of supporting several multi-modal computation-intensive tasks on their FPGAs. Since such systems are mostly autonomous and mobile, they have rechargeable power sources and therefore, varying power budgets. They may also develop hardware faults due to radiation, thermal cycling, aging, etc. Systems must be able to sustain the performance requirements of their multi-task multi-modal workload in the presence of variations in available power or occurrence of hardware faults. This paper presents an approach for mitigating power budget variations and hardware faults (transient and permanent) by run-time structural adaptation of the SoPC. The proposed method is based on dynamically allocating, relocating and re-integrating task-specific processing circuits inside the partially reconfigurable FPGA to accommodate the available power budget, satisfy tasks’ performances and hardware resource constraints, and/or to restore task functionality affected by hardware faults. The proposed method has been experimentally implemented on the ARM Cortex-A9 processor of Xilinx Zynq XC7Z020 FPGA. Results have shown that structural adaptation can be done in units of milliseconds since the worst-case decision-making process does not exceed the reconfiguration time of a partial bit-stream.
Introduction to special issue: an exploration of child and youth care pedagogy and curriculum
Authors: Jean-Pierre Johanne , de Finney Sandrina , Blanchet-Cohen Natasha
Published: July 2021

This special issue aims to explore Canadian pedagogical and curricular practices in child and youth care and youth work preservice education with an emphasis on empirical and applied studies that centre students’ perspectives of learning. The issue includes a theoretical reflection and empirical studies with students, educators, and practitioners from a range of postsecondary programs in Quebec, Ontario, Alberta, and British Columbia. The empirical articles use various methodologies to explore pedagogical and curricular approaches, including Indigenous land- and water-based pedagogies, ethical settler frontline and teaching practices, the pedagogy of the lightning talk, novel-based pedagogy, situated learning, suicide prevention education, and simulation-based teaching. These advance our understanding of accountability and commitment to Indigenous, decolonial, critical, experiential, and participatory praxis in child and youth care postsecondary education. In expanding the state of knowledge about teaching and learning in child and youth care, we also aspire to validate interdisciplinary ways of learning and knowing, and to spark interest in future research that recognizes the need for education to be ethical, critically engaged, creatively experiential, and deeply culturally and environmentally relevant.

Alternative school discipline principles and interventions: an overview of the literature
Authors: Jean-Pierre Johanne , Parris-Drummond Sylvia
Published: July 2021

Increasing evidence shows that punitive discipline is ineffective and detrimental. Using the theory and the opportunity-to-learn conceptual framework, this literature review seeks to broaden school personnel’s knowledge of alternative discipline interventions. Searching ERIC and JSTOR databases, we looked for English language, North American literature published between 1996 and 2016 that discussed alternative individual and school-wide disciplinary approaches. The literature we found indicates that punitive measures are counter-productive; that several alternative disciplinary models share common principles; and that studies point to favourable outcomes of some alternative school discipline models. While the transition towards alternative discipline may require additional resources and years of adjustment, a healthier school climate can foster the empowerment and academic achievement of marginalized students.

Authors: Ryff Peter F
Published: July 2021

A method is presented to determine the eddy current power losses in the shell of a three-phase cylindrical arc furnace. The effect of electrode phase rotation with unbalanced electrode currents on the induced losses is shown. This study indicates the direct similarity between the induced loss distribution and the nonlinear refractory wear pattern in a furnace. Experimental results on a furnace model are included to support the theoretical work. The measured wear pattern of a section of the refractory lining in a furnace is included to illustrate the corresponding qualitative distributions.
Contrast-enhanced ultrasonography for real-time monitoring of interstitial laser thermal therapy in the focal treatment of prostate cancer
Authors: Atri Mostafa , Gertner Mark R. , Haider Masoom A. , Weersink Robert A. , Trachtenberg John
Published: July 2021

Introduction: We report a case study of the application of contrastenhanced ultrasonography (CEUS) for intraoperative monitoring of thermal ablation of a single focus of prostate cancer. Methods: A patient presented with biopsy-proven, solitary-focus, low-risk prostate cancer and was recruited into a clinical trial of interstitial laser thermal focal therapy. Multiparametric magnetic resonance imaging (MRI) was used to locate the single dominant focus, and photothermal ablation was performed at the tumour site under the guidance of transrectal ultrasonography. Transrectal CEUS using systemic bolus injections of the intravascular contrast agent Definity was performed immediately before, several times during and on completion of therapy. Lesions observed on CEUS were compared with treatment effect as measured by tissue devascularization on 1-week gadolinium (Gd)–enhanced MRI. Results: Baseline images showed CEUS contrast-agent signal throughout the prostate. During and after treatment, large hypocontrast regions were observed surrounding the treatment fibres, indicating the presence of an avascular lesion resulting from photothermal therapy. Lesion size was found to increase during the delivery of thermal energy. Lesion size measured using CEUS (16 × 11 mm) was similar to the 7-day lesion measured using Gd-enhanced T1-weighted MRI. Conclusion: Focal therapy for prostate cancer requires both complete treatment of the dominant tumour focus and minimal morbidity. The application of CEUS during therapy appears to provide an excellent measure of the actual treatment effect. Hence, it can be used to ensure that the therapy encompasses the whole target but does not extend to surrounding critical structures. Future clinical studies are planned with comparisons of intraoperative CEUS to Gd-enhanced MRI at 7 days and whole-mount pathology samples.

Background
Even in the presence of promising biomedical treatment as prevention, HIV incidence among men who have sex with men has not always decreased. Counseling interventions, therefore, continue to play an important role in reducing HIV sexual transmission behaviors among gay and bisexual men and other men who have sex with men. The present study evaluated effects of a small-group counseling intervention on psychosocial outcomes and HIV sexual risk behavior.
Method
HIV-positive (HIV+) peer counselors administered seven 2-hour counseling sessions to groups of 5 to 8 HIV+ gay and bisexual men. The intervention employed information provision, motivational interviewing, and behavioral skills building to reduce sexual transmission risk behaviors.
Results
There was a significant reduction in condomless anal sex (CAS) with HIV-negative and unknown HIV-status partners, from 50.0% at baseline to 28.9% of the sample at 3-month follow-up. Findings were robust even when controlling for whether the participant had an undetectable viral load at baseline. Significant reductions were also found in the two secondary psychosocial outcomes, loneliness and sexual compulsivity.
Conclusions
The findings provide preliminary evidence that this intervention may offer an efficient way of concurrently reducing CAS and mental health problems, such as sexual compulsivity and loneliness, for HIV+ gay and bisexual men.

The distributions of the J and Cox non-nested tests in regression models with weakly correlated regressors
Authors: Michelis Leo
Published: July 2021

This paper examines the asymptotic null distributions of the J and Cox non-nested tests in the framework of two linear regression models with nearly orthogonal non-nested regressors. The analysis is based on the concept of near population orthogonality (NPO), according to which the non-nested regressors in the two models are nearly uncorrelated in the population distribution from which they are drawn. New distributional results emerge under NPO. The J and Cox tests tend to two different random variables asymptotically, each of which is expressible as a function of a nuisance parameter, c, a N(0,1) variate and a χ2(q) variate, where q is the number of non-nested regressors in the alternative model. The Monte Carlo method is used to show the relevance of the new results in finite samples and to compute alternative critical values for the two tests under NPO by plugging consistent estimates of c into the relevant asymptotic expressions. An empirical example illustrates the ‘plug in’ procedure.

An Investigation of GIS Overlay and PCA Techniques for Urban Environmental Quality Assessment: A Case Study in Toronto, Ontario, Canada
Authors: Faisal Kamil , Abdelrahman Ahmed
Published: July 2021

The United Nations estimates that the global population is going to be double in the coming 40 years, which may cause a negative impact on the environment and human life. Such an impact may instigate increased water demand, overuse of power, anthropogenic noise, etc. Thus, modelling the Urban Environmental Quality (UEQ) becomes indispensable for a better city planning and an efficient urban sprawl control. This study aims to investigate the ability of using remote sensing and Geographic Information System (GIS) techniques to model the UEQ with a case study in the city of Toronto via deriving different environmental, urban and socio-economic parameters. Remote sensing, GIS and census data were first obtained to derive environmental, urban and socio-economic parameters. Two techniques, GIS overlay and Principal Component Analysis (PCA), were used to integrate all of these environmental, urban and socio-economic parameters. Socio-economic parameters including family income, higher education and land value were used as a reference to assess the outcomes derived from the two integration methods. The outcomes were assessed through evaluating the relationship between the extracted UEQ results and the reference layers. Preliminary findings showed that the GIS overlay represents a better precision and accuracy (71% and 65%), respectively, comparing to the PCA technique. The outcomes of the research can serve as a generic indicator to help the authority for better city planning with consideration of all possible social, environmental and urban requirements or constraints.
Dimensions of perfectionism and constructive thinking as a coping response
Authors: Flett Gordon L , Russo Frank , Hewitt Paul L
Published: July 2021

The present study examined perfectionism and general coping ability as assessed by a new measure of constructive thinking. A sample of 77 students completed the Multidimensional Perfectionism Scale (MPS) and the Constructive Thinking Inventory (CTI). The MPS provides measures of selforiented, other-oriented, and socially prescribed perfectionism, while the CTI provides various measures, including summary scores of global constructive thinking, emotional coping, behavioral coping, categorical thinking, personal superstitious thinking, naive optimism, and esoteric thinking. Subjects also completed a measure of depressive symptoms so that we could examine perfectionism and coping independent of current levels of adjustment. The main finding was that socially prescribed perfectionism was associated with less constructive thinking and more negative coping across most of the CTI subscales, and these associations remained significant after removing variance due to levels of depression symptoms. Self-oriented perfectionism was adaptive in that it was associated with active forms of behavioral coping, but it was maladaptive in that it was associated with a form of emotional coping involving reduced self-acceptance. The results are discussed in terms of their implications for the cognitive treatment of perfectionists.

Published: July 2021

Background
Information technologies can facilitate the implementation of health interventions, especially in the case of widespread conditions such as pain. Tailored Web-based interventions have been recognized for health behavior change among diverse populations. However, none of the systematic reviews looking at Web-based interventions for pain management has specifically addressed the contribution of tailoring.

Methods
The aims of this systematic review are to assess the effect of tailored Web-based pain management interventions on pain intensity and physical and psychological functions. Randomized controlled trials including adults suffering from any type of pain and involving Web-based interventions for pain management, using at least one of the three tailoring strategies (personalization, feedback, or adaptation), will be considered. The following types of comparisons will be carried out: tailored Web-based intervention with (1) usual care (passive control group), (2) face-to-face intervention, and (3) standardized Web-based intervention. The primary outcome will be pain intensity measured using a self-report measure such as the numeric rating scale (e.g., 0–10) or visual analog scale (e.g., 0–100). Secondary outcomes will include pain interference with activities and psychological well-being. A systematic review of English and French articles using MEDLINE, Embase, CINAHL, PsycINFO, Web of Science, and Cochrane Library will be conducted from January 2000 to December 2015. Eligibility assessment will be performed independently in an unblinded standardized manner by two reviewers. Extracted data will include the following: sample size, demographics, dropout rate, number and type of study groups, type of pain, inclusion and exclusion criteria, study setting, type of Web-based intervention, tailoring strategy, comparator, type of pain intensity measure, pain-related disability and psychological well-being outcomes, and times of measurement. Disagreements between reviewers at the full-text level will be resolved by consulting a third reviewer, a senior researcher.

Discussion
This systematic review is the first one looking at the specific ingredients and effects of tailored and Web-based interventions for pain management. Results of this systematic review could contribute to a better understanding of the mechanisms by which Web-based interventions could be helpful for people facing pain problems.
