OPUS: Open Ulethbridge Scholarship

Open ULeth Scholarship (OPUS) is the University of Lethbridge's open access research repository. It contains a collection of materials related to research and teaching produced by the academic community.

Self-archiving your research in OPUS is one way to meet Open Access policies of granting agencies. It is important to retain your final, post-peer-reviewed drafts for submission to OPUS, as this is often the only version publishers will allow to be archived.

A pedogogical venturing into the Three Sisters' garden: lessons of attunement and reciprocity in education
(University of Calgary, 2020) Skuce, Tim; Pelech, Sharon
This paper explores the connections the authors make between their experiences in the classroom and the powerful work of Robin Wall Kimmerer (2013) in Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge, and the Teaching of Plants; specifically, her chapter entitled “The Three Sisters.” Through Kimmerer’s work, we interpret our own experiences within the classroom. We also draw upon Hans-Georg Gadamer’s philosophical hermeneutics in general and his notion of Erfahrung in particular. We were inspired by the author’s insights into how she happened upon a “new teacher” for her students. As a result, this paper explores her work, as it provides an image of what it is to be present among students while honouring the topic’s own being and becoming--staying open to its future possibilities not yet known. The pedagogical turn away from predetermined outcomes to reciprocity, interconnectedness, and relationships is examined in how they help us understand teaching and learning.

This meat or that alternative? How masculinity stress influences food choice when goals are conflicted
(Frontiers Media, 2023) Leary, R. Bret; Mesler, Rhiannon M.; Montford, William J.; Chernishenko, Jennifer
Introduction: This research integrates literature on masculinity stress—the distress experienced as the result of a perceived discrepancy with male gender norms—with research on goal conflict to examine preferences for plant-based meat alternatives (PBMAs). Men experiencing masculinity stress are likely to hold salient a goal of being masculine, which should lead to less preference for PBMAs. However, many of these men simultaneously hold competing goals, such as making ethical food choices, which remain inhibited in favor of the focal masculinity goal. We argue that once men experiencing masculinity stress highlight their masculinity through the selection of a manly product, they satisfy that higher-order goal and are then free to pursue previously inhibited goals, such as making an ethical choice through the selection of PBMAs. Methods: We present the results of three studies supporting these expectations. Study 1 tests the link between masculinity stress and meat (alternative) consumption using consumer search behavior collected from Google Trends, showing that masculinity stress is positively (negatively) correlated with searches for red meat (PBMAs). Study 2 shows that men experiencing masculinity stress are more inclined to choose PBMAs, provided they are presented within a masculine product context. Study 3 presents a parallel mediation model, showing that ethical considerations (as opposed to masculine goals) shape the choice of PBMA preference. Results and discussion: We conclude with a discussion of theoretical implications for the impression management strategies utilized by men experiencing masculinity stress and practical implications for the growing PBMA industry.

Niitsitapii heritage education: a poomiikapii approach
(Lethbridge, Alta. : University of Lethbridge, Dept. of Anthropology, 2023) Weasel Moccasin, Camina N.; University of Lethbridge. Faculty of Arts and Science; Cuellar, Andrea M.
This is a critical study of the current heritage management practices in southern Alberta, especially as they relate to Niitsitapii (Blackfoot) heritage sites. Two sites in particular, Head-Smashed-In Buffalo Jump and Writing-on-Stone / Aisinai’pi, are used as case studies for this research. Both of these sites have provincial, federal, and global designations resulting in layers of colonial policy focussed on how to best manage the heritage sites. Current heritage management directives and policies are discussed and dissected in order to understand the cultural values they represent and protect. These are compared and contrasted to Niitsitapii cultural values at the core of Niitsitapiiysinni (our way of life). Opinions from the Niitsitapii communities of Kainai and Piikanii were gathered and analyzed. From the responses / engagement received, themes began to emerge highlighting what is of importance, and value, for Niitsitapii people when it comes to managing Niitsitapii heritage. The document ends with discussing and presenting best practices that would benefit and support Indigenous led heritage management policy making.

Unsupervised detection of cell ensembles in rats' primary motor cortex during online and offline processing
(Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2023) Nazari Robati, Peyman; University of Lethbridge. Faculty of Arts and Science; Tatsuno, Masami
Motor actions engage intricate neural processes, spanning active learning phases and crucial offline periods, notably during sleep. Online learning involves diverse neural dynamics, while sleep is known for its role in skill consolidation. While numerous studies have contributed to our understanding of information processing during online and offline learning periods, these investigations have often focused on specific learning phases, leaving the intricate relationships between diverse online learning neural activities and sleep processing relatively unexplored. Here, we embarked on a comprehensive analysis aimed at unraveling the interplay between primary motor cortex (M1) neural activity during reach-to-grasp skill learning and sleep, employing an unsupervised framework. During online training, our findings uncovered four neural dynamics related to the motor execution, with compelling evidence of their replay during post-training sleep, both in Rapid Eye Movement and Slow-Wave Sleep (SWS). Moreover, our data revealed that all cell ensembles, irrespective of their dynamics during the task, exhibited substantial reactivation during spindles coupled with slow-oscillations in SWS. Further exploration on the cortico-hippocampal communication led us to investigate the activation patterns of M1 cell ensembles during hippocampal sharp-wave ripples. Our results demonstrated the dynamic suppression and enhancement modulation of M1 cell ensembles during SWS-ripples across learning days suggesting complex cortico-hippocampal dialogues associated with sensorimotor learning task. We thus contributed to understand the extensive details of neural mechanisms underlying motor learning tasks during online and offline processing periods.
