Diversidad malacológica del humedal marino-costero Las Lisas-La Barrona en el Pacífico de Guatemala
Authors: Ortiz José R. , Martínez-Dubón Rebeca M. 
Published: April 2021

Los moluscos cumplen un papel ecológico importante en los humedales marino-costeros. Forman parte de la transferencia de energía a través de las redes tróficas y contribuyen a la estructuración de los hábitats bénticos. Son uno de los grupos faunísticos dominantes en ambientes estuarinos con bosque de manglar como el humedal Las Lisas-La Barrona, ubicado en el litoral Pacífico de Guatemala. Se determinó la diversidad, abundancia y distribución de la comunidad de moluscos, así como su relación con los parámetros fisicoquímicos del agua. Se realizaron ocho muestreos (enero a agosto) en 2017, mediante la utilización de parcelas con un área de 16 m2 en seis sitios de bosque de manglar y cuatro sitios en el canal estuarino, distribuidos a lo largo del humedal. La riqueza de moluscos del humedal está comprendida por 26 especies correspondientes a 18 familias y 22 géneros. Las especies más abundantes de gastropodos fueron Cerithideopsis californica (Adams, 1852) y Littoraria fasciata (Gray, 1839) y de bivalvos Iliochione subrugosa (Wood, 1828) y Larkinia grandis (Broderip & Sowerby, 1829). Los sitios correspondientes a bosque de manglar presentaron una mayor cantidad de moluscos, principalmente gastropodos. La distribución de las especies dominantes, no está dada por los factores fisicoquímicos del agua. Algunos factores como la influencia de agua marina dentro del humedal, las altas concentraciones de oxígeno disuelto y pH ligeramente básicos, así como la calidad del agua en general, hacen del humedal Las Lisas-La Barrona un área muy diversa en cuanto a especies de moluscos.

Published: April 2021

The COVID-19 pandemic has currently affected more than 200 countries and caused around four million cases. Face masks are recommended for preventing the contagion. The Guatemalan government issued a decree for the mandatory use of face masks in public places. In order to find out the frequency of voluntary and mandatory use of face masks by Guatemalans we conducted a case study divided in two episodes (pre and post mandatory use decree) by driving a 27.8 km car transect through 11 of the 22 zones of Guatemala City and observing the use of face mask by pedestrians walking on the sides of the transect. Pedestrians were visually classified by age category (children [< 12 years], juveniles [12-21 years], adults [21-65 years] and elders [> 65 years]) and gender. During the pre-decree observation, we registered 476 individuals using a face mask and 674 not using or using them improperly. During the post-decree observation, we registered 797 individuals using face mask and 211 not using or using them improperly. In general, the frequency of face mask use was higher in the post-decree sample. Males used masks less frequent than females, especially the elders and before the decree became mandatory. Although the mandatory use decree managed to increase the frequency of the use of the mask, there is a portion of the population that is not using it or that is using it improperly, so this should be considered by the health authorities who are dealing with the COVID-19 pandemic.
Carrying Stories From the Outside In: A Collaborative Narrative Into a Teacher Education Community
Authors: Griffin Shelley M. , Ciuffetelli Parker Darlene , Kitchen Julian 
Published: April 2021

As three professors working collaboratively in teacher education, we reflect on our participation as former graduate students in narrative research circles facilitated by Dr. Jean Clandinin (University of Alberta) and Dr. Michael Connelly (Ontario Institute for Studies in Education, University of Toronto). By drawing upon the stories that we carry from institutions outside Brock University, we inquire into how our narrative experiences inform our current positioning within a teacher education community. Situating our work within social constructionism and narrative inquiry honours our relational, co-constructed work. Reflecting on three central questions regarding our individual research circle experiences assists in understanding how our narratives overlap with our current community. We draw attention to unspoken tensions that are embedded while working in relation. We invite other scholars to consider how collaborative research circle experiences can be a powerful form of living in community and a means of enhancing scholarly writing and practice.Keywords: research circle; research writing; teacher education; narrative inquiry; social constructionism; self-study
Is There a Need for Healing in the Classroom? Exploring Trauma-Informed Education for Aboriginal Mature Students
Authors: Mordoch Elaine , Gaywish Rainey 
Published: April 2021

In this paper, we describe a perplexing pattern of behaviours in mature Aboriginal students in university studies who appear capable of being successful to complete course work, but fail due to incompletion of academic work. Despite numerous strategies to provide students with opportunities for success, these students' behaviours remain perplexing. Considering the prevalence of trauma (accident, violence, suicide) in the Aboriginal population and the intergenerational trauma of the residential school experience, we examine trauma-informed care principles and their adaption to educational systems as a potential strategy to mitigate this problem. A conceptual framework based on an Indigenous knowledge perspective of Four Lodges guides the discussion of this issue.Keywords: mature students; Aboriginal students; intergenerational trauma; residential school; care
Liminal Lives: Navigating the Spaces Between (Poet and Scholar)
Authors: Clarke C. L. 
Published: April 2021

This paper focuses on the importance of narrative beginnings to narrative inquiry, arguing that an examination of narrative beginnings is essential to positioning the researcher within the research. Through a series of personal poems, I unpack the significance of my own autobiographical beginnings from a narrative perspective, and from my proposed research on life and learning on the edges of community. In this paper, I also highlight the efficacy of employing poetic representation within a narrative inquiry. Through poetic representation, I demonstrate the liminal nature of understanding field texts and interim field texts as determined by the context of the three-dimensional narrative inquiry space, encompassing temporality, sociality, and place. Keywords: narrative inquiry; poetic representation; poetic inquiry; three-dimensional narrative inquiry space; marginalization; community; identity
The Radiance of the Small
Authors: Fidyk Alexandra , Neilsen Glenn Lorri , Nudelman Merle 
Published: April 2021

The challenge and conundrum are to integrate within ourselves the dark/light cycles of the natural world, yet flourish in times of grief and pain. But how does one lose and be grateful? How does one create harmony between body and soul? Here we explore the lessons of a snail wedded to the earth, astute in its slowness, in its minute shadow; we listen for the small-throated life; we adopt the unapologetic, razor eyes of the raven. Questions lived and explored evoke shadow-answers and other questions. What lessons can be culled in the light of healing? What can we learn by entering moments closely? The suddenness of a death can bring us back to the radiance of the small: to see by means of black and to be at home in suffering. Keywords: radiance; suffering; alchemy; mystery; descent; paradox; black
Using Art-Based Ways of Knowing to Explore Leadership and Identity With Native American Deaf Women
Authors: Paris Damara Goff 
Published: April 2021

During a phenomenological narrative study regarding the perspectives of leadership among women who are both Native and Deaf, a portion of the data collection focused on visual art as a means of interpreting what leadership meant to the participants. Participants produced visual imagery to impart their ways of knowing as women who negotiated their paths between two distinct cultures. Themes of identification with indigenous art forms, spirituality, and evolving self-identities were shared, with the participants leading the development of their artistic renderings. The participant-created visual arts highlight the significance of non-verbal modes of inquiry within Indigenous and Deaf populations.Keywords: Indigenous; Native American; Deaf; Women; Art Inquiry; Identity
Attrition, Retention, and Development of Early Career Teachers: Pan-Canadian Narratives
Authors: Kutsyuruba Benjamin , Walker Keith , Al Makhamreh Maha , Stroud Stasel Rebecca 
Published: April 2021

Our pan-Canadian research study examined the differential impact of teacher induction and mentorship programs on the early-career teachers’ retention. This article details the stories from our interview participants (N=36) in relation to what their lived experiences were during their first years of teaching and how they dealt with the requirements, expectations, and challenges. Their narratives were analyzed through the lenses of early career teacher attrition, retention, and development. Our findings showed that despite geographic, contextual and policy differences, there were striking similarities in teachers’ lived experiences and in the impact of these experiences on their decisions to stay or leave and predispositions towards personal and professional development as teachers.
Innovating in the Margins of Teacher Education: Developing a Bridging Program for Internationally Educated Teachers
Authors: Wimmer Randolph , Young Beth , Xiao Jing 
Published: April 2021

In this article, we discuss our recent and current efforts to offer an innovative form of ongoing teacher education designed explicitly for Internationally Educated Teachers (IETs), which might be considered a type of in-service teacher education. We share some of the observations of IETs who have completed the Faculty of Education’s Bridging Program at the University of Alberta as well as our own experiences. Aspects of the program’s curriculum are described such as its framework including the organization of a bridging seminar and field experiences/practicum. To provide context, we review relevant policies and the limited but valuable research from other Canadian bridging programs for IETs. We conclude with a discussion of the most significant changes we have made to practices at the University of Alberta and address the issue of sustainability.

Unleashing the Learners: Teacher Self-Efficacy in Facilitating School-Based Makerspaces
Authors: Koole Marguerite , Anderson Kerry , Wilson Jay 
Published: April 2021

This qualitative research project explored the key characteristics, attitudes, and experiences of makerspace facilitators in Saskatchewan. The aim was to gather knowledge and wisdom from early adopters of makerspace from a variety of contexts ranging from tinkerspaces to increasingly popular school-based spaces in order to inform early and career-educators of the skills and attitudes conducive to creating and leading dynamic activity spaces. The questions for the semi-structured interviews were based on Bandura’s (1977; 1997) self-efficacy expectations: performance accomplishments, vicarious experience, verbal persuasion, and emotional arousal. The findings align with those of other studies in that they point towards key areas of experience: the value of productive failure, relinquishing control, and modes of support. We conclude that there is a need to help preservice and early career educators to become prepared and confident makerspace facilitators. To this end, we offer four suggestions for new makerspace facilitators: aim towards unleashing, allow others to be the experts and leaders, celebrate success and failure, and openly seek and offer support.

Published: April 2021

Objective: The aim of the study was to determine the risk factors associated with specific subtypes of urinary incontinence (UI).
Materials and Methods: This cross-sectional study was conducted between September 2013 and July 2014. There were 1459 patients included in our study. Of these, 958 women were incontinent, and 501 were continent. The Turkish version of the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), urogynecologic and pelvic examination were used for UI diagnosis. Patients' detailed medical histories were obtained. Categorical variables were evaluated using Pearson’s Chi-squared test. One-way Analysis of Variance and Kruskall-Wallis tests were used to analyze continous variables. Multiple logistic regression analysis was used to obtain statistically significant UI-associated risk factors.
Results: A history of giving birth to a baby weighing >4000 gr, early age at menarche, menopause, constipation, coffee consumption, asthma, lumbal disc hernia, family history, and recurrent urinary infections were associated with all types of UI. Delivery at home increased the risk of both stress and urge urinary incontinence (SUI and UUI, respectively). Cystocele and rectocele increased the risk of both SUI and mixed urinary incontinence (MUI). The risk of UUI was shown to increase in women who were receiving hormone replacement therapy and who had cuff prolapse. High body mass index was indicated as a specific risk factor for MUI.
Conclusions: Determining risk factors and high risk women is very important for development of preventative medical approaches for UI.

Abstract
The Helioseismic and Magnetic Imager (HMI) on board NASA’s Solar Dynamics Observatory produces estimates of the photospheric magnetic field, which are a critical input to many space weather modeling and forecasting systems. The magnetogram products produced by HMI and its analysis pipeline are the result of a per-pixel optimization that estimates solar atmospheric parameters and minimizes disagreement between a synthesized and observed Stokes vector. In this paper, we introduce a deep-learning-based approach that can emulate the existing HMI pipeline results two orders of magnitude faster than the current pipeline algorithms. Our system is a U-Net trained on input Stokes vectors and their accompanying optimization-based Very Fast Inversion of the Stokes Vector (VFISV) inversions. We demonstrate that our system, once trained, can produce high-fidelity estimates of the magnetic field and kinematic and thermodynamic parameters while also producing meaningful confidence intervals. We additionally show that despite penalizing only per-pixel loss terms, our system is able to faithfully reproduce known systematic oscillations in full-disk statistics produced by the pipeline. This emulation system could serve as an initialization for the full Stokes inversion or as an ultrafast proxy inversion.

Abstract
We present the first joint NuSTAR and NICER observations of the ultracompact X-ray binary (UCXB) 4U 1543−624 obtained in 2020 April. The source was at a luminosity of L
0.5−50 keV = 4.9(D/7 kpc)2 × 1036 erg s−1 and showed evidence of reflected emission in the form of an O viii line, Fe K line, and Compton hump within the spectrum. We used a full reflection model, known as xillverCO, that is tailored for the atypical abundances found in UCXBs, to account for the reflected emission. We tested the emission radii of the O and Fe line components and conclude that they originate from a common disk radius in the innermost region of the accretion disk (R
in ≤ 1.07 R
ISCO). Assuming that the compact accretor is a neutron star (NS) and the position of the inner disk is the Alfvén radius, we placed an upper limit on the magnetic field strength to be B ≤ 0.7(D/7 kpc) × 108 G at the poles. Given the lack of pulsations detected and position of R
in, it was likely that a boundary layer region had formed between the NS surface and inner edge of the accretion disk with an extent of 1.2 km. This implies a maximum radius of the neutron star accretor of R
NS ≤ 12.1 km when assuming a canonical NS mass of 1.4 M
⊙.
Allesfitter: Flexible Star and Exoplanet Inference from Photometry and Radial Velocity
Authors: Günther Maximilian N. , Daylan Tansu 
Published: April 2021

Abstract
We present allesfitter, a public and open-source Python software for flexible and robust inference of stars and exoplanets given photometric and radial velocity data. Allesfitter offers a rich selection of orbital and transit/eclipse models, accommodating multiple exoplanets, multistar systems, transit-timing variations, phase curves, stellar variability, starspots, stellar flares, and various systematic noise models, including Gaussian processes. It features both parameter estimation and Bayesian model selection, allowing either a Markov Chain Monte Carlo or Nested Sampling fit to be easily run. For novice users, a graphical user interface allows all input and perform analyses to be specified; for Python users, all modules can be readily imported into any existing script. Allesfitter also produces publication-ready tables, LaTeX commands, and figures. The software is publicly available (https://github.com/MNGuenther/allesfitter), pip-installable (pip install allesfitter), and well documented (www.allesfitter.com). Finally, we demonstrate the software’s capabilities in several examples and provide updates to the literature where possible for Pi Mensae, TOI-216, WASP-18, KOI-1003, and GJ 1243.
Self-supervised Representation Learning for Astronomical Images
Authors: Hayat Md Abul , Stein George , Harrington Peter , Lukić Zarija , Mustafa Mustafa 
Published: April 2021

Abstract
Sky surveys are the largest data generators in astronomy, making automated tools for extracting meaningful scientific information an absolute necessity. We show that, without the need for labels, self-supervised learning recovers representations of sky survey images that are semantically useful for a variety of scientific tasks. These representations can be directly used as features, or fine-tuned, to outperform supervised methods trained only on labeled data. We apply a contrastive learning framework on multiband galaxy photometry from the Sloan Digital Sky Survey (SDSS), to learn image representations. We then use them for galaxy morphology classification and fine-tune them for photometric redshift estimation, using labels from the Galaxy Zoo 2 data set and SDSS spectroscopy. In both downstream tasks, using the same learned representations, we outperform the supervised state-of-the-art results, and we show that our approach can achieve the accuracy of supervised models while using 2–4 times fewer labels for training. The codes, trained models, and data can be found at https://portal.nersc.gov/project/dasrepo/self-supervised-learning-sdss.
