Cégep de Rimouski

Abstract. We created a virtual tour application using photogrammetry, GIS data, and a game engine to allow a greater audience to discover in an immersive way the wooden scale model (scale 1:1000) of a Utopian version of the city of Rimouski imagined by the architect Luc Laporte. In this paper, we show how we determined, based on the quality requirements for video game assets (texel density), what are the conditions to be met during photogrammetry survey (GSD) of such a scale model intended to a virtual tour application. We explain how creating a 3D version of Laporte’s wooden model is a problem very similar to air-based photogrammetry of urban spaces but, contrary to typical aerial photogrammetry where the distance d is much greater than the focal length f, we are strongly limited by the depth of field as, for the scale model, the distance is only somewhat greater than the focal length, yielding a reduced depth of field.

ABSTRACTIn this study, Indigenous Knowledge Holders were gathered in a collaborative forum to discuss weather, in particular, Indigenous Science knowledge related to severe weather, climate change, and weather prediction methods. Weather forecasting methods that arose in discussion were further explored based on a framework of Bridging, Braiding, and Weaving knowledge systems. Numerous Indigenous Science‐based weather prediction methods were documented, with most lending themselves to follow‐up testing. The Knowledge Holders emphasized that Indigenous Science is an important component within the broader domain of Indigenous Traditional Knowledge, with current and historic empirical and holistic insights into natural phenomena. There was consensus among the Knowledge Holders that Indigenous Science should not be perceived as subordinate to Western methodologies but instead viewed as a complementary and equivalent knowledge system. This paper underscores the importance of a co‐produced approach to research where Indigenous Knowledge Holders share their expertise to enrich and inform Western research design, including the interpretation of study results and the implementation of subsequent policy and decision‐making. We provide examples of Bridging, Braiding, and Weaving Indigenous Science using weather‐related phenomena, such as animal behavior, atmospheric patterns, and plant growth indicators, while also offering insights into the impacts of climate change and severe weather.

ABSTRACT Despite its deadly nature, extreme heat has received fragmented and scattered responses in cities, often overlooking the crucial social and equity components. Dominant adaptation approaches have paid little attention to chronic socio-economic vulnerabilities to heat stress, resulting in a lack of strategic planning to address them. Building upon critical urban studies and adaptation scholarship, this article examines how the dynamics of urban climate adaptation in the Global North have sidestepped the root causes of heat vulnerability and their (re)production in past, present and future practices of uneven urban development and planning under austerity. We investigate this empirically in attending to the framing of adaptation, the instruments used and the biases they introduce in Montreal (Canada), as well the perception from planners and community groups regarding their agency in responding to extreme heat. We contribute to the literature in analysing how the urban governance of adaptation in urban planning tends to silence the social production of vulnerabilities by three intersecting processes: the biases of instruments used, the unacknowledged legacies of uneven urban development, and the lacking recognition and support for community organisations caring practices.

A 2-meter (79 in) diameter and 4.5-meter (180 in) tall Viking buoy, built by the Canadian company MTE Instruments, served as offshore platform in the operation of an RBR Concerto CTD connected to an autonomously operated profiling winch. The CTD was attached to MTE Instrument's Mini Winch to record time series data of the water column's physical properties from surface to seafloor at 20m depth in support of an autonomous vehicle test area. Data acquisition and power management of the winch were handled by the main buoy controller. Meteorological and oceanographic sea state conditions for operation of the winch were monitored in real time by the winch and buoy controllers to ensure safe deployment and recovery of the CTD into the water from its in-hull storage tube, thus avoiding entanglement with the anchor chain. Storage of the CTD in a hull mounted tube above the water line kept the CTD sensors from biofouling. Full time series data were stored on the buoy and data snippets were transmitted to shore in near real time via iridium data burst. These data were subsequently quality controlled and are publicly available from NOAA (National Oceanic & Atmospheric Administration) NDBC (National Data Buoy Center) data servers. Here we report on the autonomously collected CTD and ADCP (Acoustic Doppler Current Profiler) data collected during that deployment.

Abstract Ignoring cultural differences can cause unfavourable situations and negatively influence the success of production internationalization projects. A decision to subcontract part of the production or to produce in a foreign country, requires identifying and controlling the risks related to cultural differences. Our research objective was to study these risks and the business practices used to face them. In order to reach this objective, we studied eight (8) Canadian manufacturing companies, that outsourced part of their production to China. Results show that the risks related to cultural differences, can provoke an important divergence between requirements of the Canadian company and the resulting products manufactured by the Chinese subcontractor and cause an additional unexpected manufacturing cost. The risk of misunderstanding and difficulty communicating in addition to difficulty applying quality control practices were critical for most of the studied companies’ managers. However, the identified risks could be controlled with different business practices, which we classified according to their role of mitigation or contingency. Frequent interaction with Chinese partners, developing a good trust-based relationship with them and finding ways of encouraging them to get more involved in the partnership and to suggest solutions and innovations represent some of the important practices to adopt. JEL classification numbers: M1. Keywords: Cultural differences, Production internationalization, International outsourcing, Outsourcing in China, Risk management, Cross-cultural management.

Forest trees are the world’s most important renewable natural resources in terms of their dominance among other biomasses and the diversity of molecules that they produce. Forest tree extractives include terpenes and polyphenols, widely recognized for their biological activity. These molecules are found in forest by-products, such as bark, buds, leaves, and knots, commonly ignored in forestry decisions. The present literature review focuses on in vitro experimental bioactivity from the phytochemicals of Myrianthus arboreus, Acer rubrum, and Picea mariana forest resources and by-products with potential for further nutraceutical, cosmeceutical, and pharmaceutical development. Although these forest extracts function as antioxidants in vitro and may act on signaling pathways involved in diabetes, psoriasis, inflammation, and skin aging, much still remains to be investigated before using them as therapeutic candidates, cosmetics, or functional foods. Traditional forest management systems focused on wood must evolve towards a holistic approach, allowing the use of these extractives for developing new value-added products.
