Prior work has suggested that rime (vowel) information is given priority over tone information in the perception of isolated words but there are flipped roles of tone and rime in a semantically constraining context. Here, I examined the eye gaze of native listeners of Mandarin Chinese, asking when and how top-down contextual effects from hearing a noun classifier constrains real-time processing of a target noun, and whether this classifier context has differential impacts on activating tone and rime information. The results show that, when hearing the classifier, average looking time to the target noun and noun competitors with the same tone or rime was significantly greater than to phonologically unrelated nouns. Moreover, fixations to the target were significantly greater to the phonological competitors only in a high-constraint classifier context. In addition, there was more distraction from a tone competitor than a rime competitor only in the high-constraint context. Results suggest that segmental and lexical tone perception follow different perceptual processes, and that tone was predicted ahead of rime when perceiving spoken words in context
A conversation with Siddharth Dube, an author and activist born in Calcutta, India. Dube released his most recent book earlier this year. "An Indefinite Sentence: A Personal History of Outlawed Love and Sex" is a memoir that takes on issues of love, sexuality, and oppression through Dube\u27s personal and political journey as a gay man. Dube reads excerpts from the book and is in conversation with SFU\u27s Am Johal. Audience Q&A follows.
Visualizations play a key role in analysing, understanding, and communicating risks of flooding and possible mitigation options. In particular, 3D visualizations are becoming increasingly prominent for risk communication. At the same time, there is a growing ecosystem of mixed reality interfaces that have potential to transform our interaction with 3D data and visualizations. This thesis outlines the potential of these tools and develops a set of mixed reality flood visualization prototypes that utilize capabilities of the state-of-the-art HoloLens 2 mixed reality system. By leveraging the representational and interactive capabilities provided by hand and eye-tracking, 3D displays, spatial mapping of user environment and positional tracking, these tools provide distinct and compelling experiences of 3D flood visualizations. To illuminate the potential of these tools to support meaningful practice, this thesis reflects on the user experience, hardware performance and usability of MR visualizations
Groucho Marx perhaps said it best: “Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly and applying the wrong remedies.” Politics and politicians are always good for a laugh, but in a job that relies entirely on public opinion this might be a problem. How does one manage a political personality amidst the noise of politics? This talk features pollster and political strategist Hamish Marshall, strategist Mira Oreck and communications consultant Bob Ransford. Moderated by Vancouver Sun columnist Barbara Yaffe
This presentation examines a set of photographs held in the research archive of the Bill Reid Centre for Northwest Coast Studies at SFU. It traces shifts in meaning as they have moved from commercial, government, and museum contexts toward being held up as symbols of Indigenous pride. To view some of the photographs mentioned in the presentation, go to www.sfu.ca/brc/virtual_village.html SPEAKER BIO Bryan Myles is the Interim Director of the Bill Reid Centre for Northwest Coast Studies at SFU, where he is working on an interdisciplinary PhD that explores the changing relationship between memory, institutions and Indigenous peoples. His research interests include Indigenous cultural heritage in digital contexts, visual anthropology, postcolonial studies, and material culture. Myles\u27 doctoral research investigates the use of new and emerging media technologies to record, document, safeguard, and create access to Northwest Coast visual cultural heritage. Myles completed his Master’s degree in sociocultural anthropology at Carleton University in 2008. His M.A. thesis project examined the disjuncture between ecotourism and cultural tourism principles and practice in the Mesoamerican country of Belize. In his time with the Bill Reid Centre at SFU, Myles has been involved in numerous Northwest Coast art and cultural heritage projects that draw on the visual histories of the coast and the work of historic and contemporary Northwest Coast artists
Forensic case formulation is an under-studied and growing area within the violence risk assessment literature. The current study aimed to address gaps in the literature by examining the interrater reliability (IRR) and quality of forensic case formulations by comparing Expert and Novice raters. N = 50 intimate partner violence offender files were accessed. Four raters (n = 2 Experts, n = 2 Novices) rated each file using all steps of Spousal Assault Risk Assessment Guide-Version 3 (SARA-V3; Kropp & Hart, 2015). Cases were formulated using a Decision Theory approach in which motivating, disinhibiting, and destabilizing mechanisms were identified. The distribution of ratings for these mechanisms was presented. IRR was examined using a novel coefficient, Gwet’s AC. Raters also completed narrative case formulations. Then a Within Case and Across Case paired case design involving n = 143 narrative formulation pairs was conducted with three new raters. The similarity of paired formulations was evaluated. Raters also assessed the quality of formulations using the Case Formulation Quality Checklist-Revised (CFQC-R; McMurran & Bruford, 2016). For most formulation mechanisms, distribution of Presence ratings was skewed. Overall, across Experts and Novices, the IRR of formulation mechanisms ranged from poor to almost perfect (AC2 = .10. - .98), with most coefficients falling between the moderate and almost perfect ranges. The similarity of formulations was established; Within Case paired formulations were judged as more similar than Across Case paired formulations. Finally, formulations were high in quality; Experts produced higher quality formulations than Novices
In a 2012 editorial, the well-respected scientific journal Nature called out the Harper government for muzzling Canadian scientists, claiming it was not allowing scientists to speak freely about their research. Science, ideally, is objective, universal and disinterested, but what happens when politics get in the way? How, as citizens, are we to first understand the scientific signal from the noise, and, second, know when it is presented without an agenda? In a world where it’s getting harder and harder to discern the PR policy press release from objective scientific research, award-winning journalist and writer Chris Turner joins writer, broadcaster and composer Paolo Pietropaolo to discuss the changing nature of science communication
In a rare Vancouver appearance, Coleman Barks leads the audience on a journey through the life and works of Rumi. His recitations will be accompanied, as Sufi poetry often was, with music. On stage with Barks are a group of exceptional musicians. On the barbat (precursor to the Persian oud) is the foremost player of the instrument, Iranian musician Hossein Behroozinia. Behroozinia performed with Barks on his last Vancouver visit, almost a decade ago, at the Chan Centre. On sitar is maestro Mohamed Assani. The musicians will trace Rumi\u27s own life journey, by playing music from Afghanistan, Iran and Turkey.
The evening’s discussion is around what Vancouver’s heritage is and what heritage values ought to be recognized. We then tie these values to a discussion of the Heritage Register, an inventory that identifies approximately 2,200 heritage sites and resources. The register is and has been a fundamental component of heritage conservation in our city but it needs to be updated. The panellists will discuss how our existing register can be improved so that it reflects and recognizes a broad range of heritage values, beyond just the architectural. A general discussion with the audience follows and at the end, everyone will be invited to submit feedback on the evening’s topic to the consultants leading the Heritage Action Plan
It is often difficult in capture-recapture (CR) studies of grizzly bear populations to determine the age of detected bears. As a result, analyses often omit age terms in CR models despite past studies suggesting age influences detection probability. This paper explores how failing to account for age in the detection function of an open, spatially-explicit CR model, introduced in Efford & Schofield (2019), affects estimates of apparent survival, apparent recruitment, population growth, and grizzly bear home-range sizes. Using a simulation study, it was found that estimates of all parameters of interest excluding home-range size were robust to this omission. The effects of using two different types of detectors for data collection (bait sites and rub objects) on bias in estimates of above parameters was also explored via simulation. No evidence was found that one detector type was more prone to producing biased parameter estimates than the other
