Title: Barefoot running: Minimal shoes for minimal injury?
Author(s): Cassidy R. Penney (author)
Date: 2020
Abstract: Running features repetitive, impactful movements resulting in 79% of runners getting injured each year (Altman & Davis, 2012). Ground reaction forces while running can reach between 2.5-2.8 times a person’s body weight and must be dissipated properly to prevent injury (Cavanagh & LaFortune, 1980). Rearfoot strikers generate a higher impact peak in comparison to forefoot strikers (Daoud et al, 2012). Running with shorter stride lengths can also reduce the peak vertical ground reaction force (Heiderscheit, Chumanov, Michalski, Wille, & Ryan, 2011). It is hypothesized that runners who are barefoot will run with shorter strides and a mid or forefoot strike pattern thus reducing the ground reaction force that must be absorbed by the limbs of the runner (Liebermen et al, 2010).

Title: Workshop: Ambiguity, empathy and narrative co-design: The user experience of reading dementia care comic
Author(s): Ernesto Priego (author), Simon Grennan (author), Peter Wilkins (author)
Date: 2020
Abstract: Conference presentation delivered at the 11th International Graphic Novels and Comics Conference (July 2020, online format).
The World Health Organisation has anticipated that by 2030, 82 million people will have dementia and 152 million by 2050. In this user-centred online workshop, participants will read, compare and discuss two short comic books resulting from user-centred design and narrative research design methods: Parables of Care: creative responses to dementia care (Grennan, Priego, Sperandio, Wilkins 2017) and I Know How This Ends: Stories of Dementia Care (Priego, Wilkins, Martins, Grennan 2020). Enabled by screen/document sharing via videoconferencing software, participants will 'user-test' both comics, interrogating concepts of ambiguity, fracture, empathy and the genres of the parable and tragedy, and will be prompted to discuss the challenges and opportunities for co-desinging their own creative responses in comics form. The workshop seeks to test the hypotheses and motivations behind both comics and will allow participants to discuss and provide direct feedback on the narrative co-design methods employed in the creation of both comic books, in a practical effort to fully place the users/readers in the centre of the research and development cycle.

Title: The business of managing nurses’ substance‐use problems
Author(s): Charlotte A. Ross (author), Sonya L. Jakubec (author), Nicole S. Berry (author), Victoria Smye (author)
Date: 2020
Abstract: Nurses’ experiences in, and the overall effectiveness of, widely used alternative‐ to‐discipline programs to manage nurses’ substance‐use problems have not been adequately scrutinized. We uncovered the conflicted official and experiential ways of knowing one such alternative‐to‐discipline program in a Canadian province. We explicated this conflict through an institutional ethnography analysis. Ethnographic data from interviews with 12 nurses who were enrolled in an alternative‐to‐discipline treatment program and three program administrators, as well as institutional texts, were analyzed to explore how institutional practices and power relations co‐ordinated and managed nurses’ experiences. Analysis revealed the acritical acceptance of a standardized program not based on current norms of practice. Potential and actual conflicts of interest, power imbalances, and prevailing corporate interests were rife. Nurses were not afforded the same rights to quality ethical health care as other citizens. ‘Expert’ physicians’ knowledge was privileged while nurses’ knowledge was subordinated. Conclusions were that regulatory bodies cannot rely on the taken‐for‐granted standardized treatment model in widespread use. Individualized treatment alternatives reflecting current, scientific evidence must be offered to nurses, and nurses’ knowledge, expertise, and experiences need to be included in decision‐making processes in these programs.

Title: The early temperamental correlates of antisocial propensity
Author(s): Jeffrey R. Mathesius (author), Patrick Lussier (author), Raymond R. Corrado (author)
Date: 2020
Abstract: The three CAD domains are likely dimensional, not categorical. • More concerning temperament profiles can be identified by at least 3 years of age. • Negative emotionality may be important to the development of impulsive and sensation-seeking behaviors during childhood. • Negative emotionality may be important to the development of prosocial values during childhood.

Title: Think before you judge: The link between mental illness and smoking cigarettes
Author(s): Christine Klassen (author)
Date: 2020
Abstract: Individuals with mental illness living independently in the community engage in unhealthy lifestyle choices, such as smoking cigarettes. The purpose of this project was to explore factors that may increase the likelihood of persons with mental illness to smoke cigarettes. From the six participants that were interviewed, themes such as relaxation, stress relief, clarity, energy, a good start to the day and social benefits emerged. The project also served as a lens into identifying barriers to quitting smoking for those with mental illness. In light of these findings, public education initiatives as well as smoking cessation programs could serve the mental health demographic by incorporating motivation, barriers and clients’ needs in their intervention protocols.

Title: Correlation of thyroid hormone measurements with thyroid stimulating hormone stimulation test results in radioiodine‐treated cats
Author(s): Jennifer Wakeling (author), Teresa Hall (author), Timothy L. Williams (author)
Date: 2020
Abstract: [Background] Iatrogenic hypothyroidism can develop after radioiodine‐I131 (RAI) treatment of hyperthyroid cats and can be diagnosed using the thyroid stimulating hormone (TSH) stimulation test. [Objectives] To assess the effect of noncritical illness on TSH stimulation test results in euthyroid and RAI‐treated cats. To assess the correlation of low total‐thyroxine (tT4), low free‐thyroxine (fT4), and high TSH concentrations with TSH stimulation test results. [Animals] Thirty‐three euthyroid adult cats and 118 client‐owned cats previously treated with RAI. [Methods] Total‐thyroxine, fT4, and TSH were measured, and a TSH stimulation test was performed in all cats. Euthyroid control cats were divided into apparently healthy and noncritical illness groups. RAI‐treated cats were divided into RAI‐hypothyroid (after‐stimulation tT4 ≤ 1.5 μg/dL), RAI‐euthyroid (after‐stimulation tT4 ≥ 2.3 μg/dL OR after‐stimulation tT4 1.5‐2.3 μg/dL and before : after tT4 ratio > 1.5), and RAI‐equivocal (after stimulation tT4 1.5‐2.3 μg/dL and tT4 ratio < 1.5) groups. [Results] Noncritical illness did not significantly affect the tT4 following TSH stimulation in euthyroid (P = .38) or RAI‐treated cats (P = .54). There were 21 cats in the RAI‐equivocal group. Twenty‐two (85%) RAI‐hypothyroid cats (n = 26) and 10/71 (14%) of RAI‐euthyroid cats had high TSH (≥0.3 ng/mL). Twenty‐three (88%) RAI‐hypothyroid cats had low fT4 (<0.70 ng/dL). Of the 5 (7%) RAI‐euthyroid cats with low fT4, only one also had high TSH. Only 5/26 (19%) RAI‐hypothyroid cats had tT4 below the laboratory reference interval (<0.78 μg/dL). [Conclusions and Clinical Relevance] The veterinary‐specific chemiluminescent fT4 immunoassay and canine‐specific TSH immunoassay can be used to aid in the diagnosis of iatrogenic hypothyroidism in cats.

Title: Feeding lifestyles of the Phytoseiidae revisited: Searching for a factitious rearing host for Neoseiulus fallacis (Acari: Phytoseiidae)
Author(s): Robert McGregor (author), Katelyn Crisp (author), Camile Castiglia (author)
Date: 2020
Abstract: Several mite species from the Phytoseiidae (Acari) have been successfully developed as products for augmentative biological control. Rearing of mites using factitious prey in grain-based systems can increase the efficiency of production of phytoseiids. This has been done successfully for several species but usually for Type III (generalist predator) phytoseiids. Neoseiulus fallacis (Garman) (Acari: Phytoseiidae) is a Type II phytoseiid (prefers spider mites) that is currently reared in British Columbia (Canada) on Tetranychus urticae Koch (Acari: Tetranychidae) in a plant-based system. Here, we present feeding behaviour and predation data for N. fallacis on T. urticae and three Astigmatid (Acari) mites: Lepidoglyphus destructor (Schrank) (Acari: Glycyphagidae), Aleuroglyphus ovatus (Tropeau) (Acari: Acaridae) and Thyreophagus entomophagus (Laboulbène) (Acari: Acaridae). Our objective is to identify a candidate factitious host for mass rearing of N. fallacis. Although N. fallacis grabbed prey mites of all four species, successful feeding attempts were more frequent for the native host, T. urticae, than for the three Astigmatid species. N. fallacis rejected A. ovatus and T. entomophagus as hosts more often than T. urticae. In predation trials, N. fallacis fed at the highest rate on T. urticae, at an intermediate rate on L. destructor, and at the lowest rates on A. ovatus and T. entomophagus. For the three mites tested, L. destructor is the most promising species for further development as a factitious host for N. fallacis.

Title: Supermoms and bumbling dads: How do Mother's Day and Father's Day cards help perpetuate traditional roles in the home?
Author(s): Alison M. Thomas (author), Elizabeth Dennis (author), Tonya K. Davidson (editor), Ondine Park (editor)
Date: 2020
Abstract: The chapter, "Supermoms and bumbling dads: How do Mother's Day and Father's Day cards help perpetuate traditional roles in the home?" was written by the listed authors including Alison M. Thomas (Douglas College Faculty). Life in Canada is marked, celebrated, enjoyed, and dreaded in ways that respond specifically to the seasons. Sociological thinking allows people to ask questions about things that may otherwise be taken for granted. Thinking about the seasons sociologically opens up a unique perspective for studying and understanding social life. Each chapter in this collection approaches the seasons and the passage of time as a way to explore issues of sociological interest. The authors use seasonality as a device that can bridge, in fascinating ways, small-scale interpersonal interactions and large formal institutional structures. These contemporary, Canadian case studies are wide-ranging and include analyses of pumpkin spice lattes, policing in schools, law and colonialism, summer cottages, seasonal affective disorder, New Year’s resolutions, Vaisakhi celebrations, and more. Seasonal Sociology offers provocative new ways of thinking about the nature of our collective lives. -- FROM PUBLISHER DESCRIPTION.

Title: End-of-life management in new product development
Author(s): Majid D. Makinejad (author), Reza Ghaeli (author)
Date: 2020
Abstract: Developing a sustainable and environmentally friendly product has become the primary concern in the car manufacturing industry. The new legislation “End of Life Vehicle” increased design complexities of car modules, subsystems, and components in a way that achieves the goals of reducing, reusing and recycling materials. The car bumper system is a complicated exterior module designed to prevent physical damage, reduce aerodynamic drag force, and be aesthetically pleasing to the consumer in addition to End of Life vehicle processing, which employs dismantling, shredding and land-filling. Design for dismantling is the first step in ELV’s implementation to optimize, the separating of the components and recycling of the materials of the bumper system. This study focused on the analysis of the ELV’s value in redesigned solutions of a new car bumper system in comparison to the current bumper one (case study). It provided a guideline to address the critical considerations in selecting materials, dismantling bumpers’ components and joining bracket to facilitate dismantling, separating, and recycling.

Title: The clash of empires: regulating technological threats to civil society
Author(s): Tracey L. Dowdeswell (author), Nachshon Goltz (author)
Date: 2020
Abstract: This paper examines the regulation of technology platform companies providing a platform for user-generated media content while playing an increasingly dominant role in the global flow of news and information. In doing so, platform companies play a crucial role in modern civic life, by deciding which content will reach users, engage the public's attention, and be deemed credible. It is therefore crucial that we choose means of regulation that foster democratic values and robust civic engagement. In this paper we focus on the regulation of ‘computational propaganda', including misinformation and ‘fake news', the rise of synthetic media and so-called ‘deep fakes', and novel forms of algorithmic injustice, such as the manipulation of search engine results and their effect on elections. We argue that many existing regulations fall short in that they adopt an approach that views regulation as a battle between two competing powers, or ‘empires’ – that of the regulatory state versus the big tech companies. Accordingly, they approach regulation as a means of redistributing power between these two players, while discounting the end user, and they often involve unjustified restrictions of free speech through the imposition of content controls.

Title: From empty to angry: Extremism, modernity, and the search for identity
Author(s): Logan Macnair (author), Richard Frank (thesis advisor), Simon Fraser University Criminology (Degree granting institution)
Date: 2020
Abstract: An increase in the amount of high-profile incidents and attacks in the West perpetrated by individuals subscribing to a variety of extremist ideologies over the past decade has led to an influx of academic research concerned with uncovering how and why it is that individuals become radicalized toward ideologically-motivated extremist violence. While such research has examined a diverse range of social, demographic, and psychological variables and their potential link/correlation to the radicalization process, there has yet to emerge an accurate or reliable ‘profile’ with respect to who is more or less likely to become radicalized or join extremist/terrorist movements. The primary aim of this dissertation is to present a novel theoretical approach which centers the concept of individual identity as the fundamental factor which drives individuals in the West toward involvement with extremist movements. This theory of identity, which presupposes that macro-level structural factors fundamentally dictate how individuals experience and internalize identity on a micro-level, is outlined by tracing how the concept of ‘identity’ has historically evolved in ‘Western’ culture up to its current iteration in modern, hyper-connected, late-capitalist society. Once outlined, this theory of identity is empirically applied to the digital media content of two extremist movements via a mixed-method approach that utilizes topic modelling, sentiment analysis, and thematic/discourse analysis. More specifically, the content of the so-called Islamic State (including videos, magazines, and Twitter posts) and the user-generated comments of the notorious far-right online community r/The_Donald are examined through this theoretical lens and analyzed with this mixed-method approach. Results indicate that, wittingly or not, modern extremist movements routinely incorporate questions of identity into both their propaganda and general discussions in a manner that provides simplistic solutions and answers to the complex problems of identity and self that are created and amplified within modern Western culture. As such, this dissertation argues that the attraction of extremist ideology and the potential for extremist violence is, at current, an inevitable byproduct of modern macro-level structural and economic conditions.

Title: Library projects using agile or traditional project management: Less stress and more success
Author(s): Trevor Smith (author)
Date: 2020
Abstract: Presented online at the Access Library Technology Conference (Canada) ; October 22, 2020.
Got a big project but aren’t sure how to start (or just started and have stalled out)? Proposing a project and getting it to the finish line are very different. Trevor presented a session that discussed differences between agile and traditional project management and how they can help or hinder your project. Different software tools for handling the planning and day-to-day work were presented. The session also covered, how to schedule and figure out timelines, how to communicate with staff, patrons, or VPs. This is a general overview of Project Management and how you can prepare your library for the next challenge.

My art is killing me, and other poems

Author(s)

Amber Dawn (author)

Date

2020

Abstract

Short-listed, Jim Deva Prize for Writing that Provokes (BC and Yukon Book Prizes) 2021.

In her novels, poetry, and prose, Amber Dawn has written eloquently on queer femme sexuality, individual and systemic trauma, and sex work justice, themes drawn from her own lived experience and revealed most notably in her award-winning memoir "How Poetry Saved My Life". In this, her second poetry collection, Amber Dawn takes stock of the costs of coming out on the page in a heartrendingly honest and intimate investigation of the toll that artmaking takes on artists. These long poems offer difficult truths within their intricate narratives that are alternately incendiary, tender, and rapturous. In a cultural era when intersectional and marginalized writers are topping bestseller lists, Amber Dawn invites her readers to take an unflinching look at what we expect from writers, and from each other. Includes a foreword by writer Doretta Lau.

Title: Describing quasi-graphic matroids
Author(s): Nathan Bowler (author), Daryl Funk (author), Daniel Slilaty (author)
Date: 2020
Abstract: The class of quasi-graphic matroids recently introduced by Geelen, Gerards, and Whittle generalises each of the classes of frame matroids and lifted-graphic matroids introduced earlier by Zaslavsky. For each biased graph $(G, \mathcal B)$ Zaslavsky defined a unique lift matroid $L(G, \mathcal B)$ and a unique frame matroid $F(G, \mathcal B)$, each on ground set $E(G)$. We show that in general there may be many quasi-graphic matroids on $E(G)$ and describe them all. We provide cryptomorphic descriptions in terms of subgraphs corresponding to circuits, cocircuits, independent sets, and bases. Equipped with these descriptions, we prove some results about quasi-graphic matroids. In particular, we provide alternate proofs that do not require 3-connectivity of two results of Geelen, Gerards, and Whittle for 3-connected matroids from their introductory paper: namely, that every quasi-graphic matroid linearly representable over a field is either lifted-graphic or frame, and that if a matroid $M$ has a framework with a loop that is not a loop of $M$ then $M$ is either lifted-graphic or frame. We also provide sufficient conditions for a quasi-graphic matroid to have a unique framework. Zaslavsky has asked for those matroids whose independent sets are contained in the collection of independent sets of $F(G, \mathcal B)$ while containing those of $L(G, \mathcal B)$, for some biased graph $(G, \mathcal B)$. Adding a natural (and necessary) non-degeneracy condition defines a class of matroids, which we call biased graphic. We show that the class of biased graphic matroids almost coincides with the class of quasi-graphic matroids: every quasi-graphic matroid is biased graphic, and if $M$ is a biased graphic matroid that is not quasi-graphic then $M$ is a 2-sum of a frame matroid with one or more lifted-graphic matroids.

Title: A genetic algorithm-based method for solving multi-mode resource-constrained project scheduling problem in uncertain environment
Author(s): Mohammad Khalilzadeh (author), Seyyed H. Hosseini (author), Reza Ghaeli (author)
Date: 2020
Abstract: Project scheduling models with resource constraints and multi-mode activities aims to create a schedule for carrying out activities considering precedence constraints and available resources in order to minimize the project duration. In the real world, we face uncertainty related to projects, where there are no historical data, hence, we should rely on the experts' judgements to estimate activity durations. For this purpose, in this paper, the 99-simulation method is used to deal with uncertainty. The exact mathematical programming model is presented in this paper and the hybrid algorithm based on Genetic Algorithm is used to solve this type of project scheduling problem which finds the near-optimal solution in a short computational time. Finally, the effectiveness of the proposed model is examined with a numerical example.

Abstract: Genetic data on threatened plant populations can facilitate the development of adequate conservation strategies to reduce extinction risk. Such data are particularly important for species affected by habitat fragmentation such as Magnolia cubensis subsp. acunae, a Critically Endangered magnolia subspecies endemic to Cuba. Using genetic data from 67 individuals, we aimed to evaluate the effect of habitat fragmentation on two subpopulations in the Guamuhaya mountain range, in Topes de Collantes Protected Natural Landscape and Lomas de Banao Ecological Reserve. We characterize the structure and genetic diversity of these subpopulations, with the objective of managing their conservation more effectively. We used Landsat satellite images to determine land-cover types at the two locations and calculated indices of habitat fragmentation. For genetic analyses, we extracted DNA from the leaf tissue of individuals from the two subpopulations and used 11 microsatellite markers to genotype them. We calculated heterozygosity, allelic richness and the F-statistics, to evaluate genetic variability. The montane rainforest in Topes de Collantes was most affected by habitat fragmentation, with smaller patches of more irregular shapes, compared to submontane forest at this location and both montane and submontane forests in Lomas de Banao. Genetic diversity was higher in Topes de Collantes, but we found no genetic differentiation between subpopulations. Our findings suggest the two subpopulations can be considered a single evolutionary unit and conservation entity. We propose to use individuals from both subpopulations for reinforcement to increase the overall genetic diversity of the subspecies.[ABSTRACT FROM AUTHOR]

Title: Barriers and facilitators to the use of progress-monitoring measures in psychotherapy
Author(s): Gabriela Ionita (author), Gabrielle Ciquier (author), Marilyn Fitzpatrick (author)
Date: 2020
Abstract: Progress-monitoring (PM) measures, which help ensure evidence-based practice, allow the tracking of client progress in psychotherapy treatment and even predict which clients will have negative outcomes. However, the majority of psychologists in Canada still do not use these measures in clinical practice. The purpose of the present study was to investigate the barriers and facilitators to the use of PM measures in psychotherapy among psychologists in Canada. Participants included 533 licensed psychologists from across Canada who responded to an online survey regarding the barriers and facilitators involved in using PM measures in clinical practice. Participants self-identified as either users, nonusers, or previous users of PM measures. The results of the present study indicate that the top-4 barriers to using PM measures were limited knowledge, limitations in training, burden on clients, and concerns regarding additional work and time. These barriers were similar across users, nonusers, and previous users. The results suggest that offering training in different formats, over extended periods of time, and from colleague to colleague may be the most effective approach to overcoming these barriers. Other strategies that may help address the identified barriers and implications for practicing clinicians and the field of psychology are discussed.

Abstract

Presented at The International Society for the Scholarship of Teaching and Learning (ISSOTL) Conference, Atlanta, Georgia (October, 2019).

From the conference program: As SoTL inspires more and more people to explore student learning in their own classrooms it is helpful to share our research experiences, not just our findings, since many start out unfamiliar with this form of research. Here I discuss some of the issues I encountered while conducting a longitudinal study of student learning trajectories in introductory sociology. These included addressing important ethical concerns about my dual role as both instructor and researcher, as well as deciding on various different methods of data collection, both qualitative (analysis of learning dossiers and concept maps) and quantitative (scores for written test answers).

Title: Parables of care: I know how this ends, stories of dementia care
Author(s): Ernesto Priego (author), Peter Wilkins (author), Melissa Martins (author), Simon Grennan (author)
Date: 2020
Abstract: I Know How This Ends is the second volume in a series that started with Parables of Care: Creative Responses to Dementia Care (2017). The project explores the potential of comics to enhance the impact of dementia care research. This comic book presents, in synthesised form, stories crafted from narrative data collected via interviews with professional caregivers, educators, and staff at Douglas College in Vancouver, Canada, who have cared for relatives and people with dementia in hospital.The intention of the book is to show the importance of feeling in care-giving, the professional aspects of which are sometimes at odds with the family systems aspect of dementia.
