Resource assessment

description: The tidal current energy resource is challenging to assess with accuracy and precision. An accepted standard methodology is lacking, which in turn perpetuates uncertainty and hinders the industry’s development. Technical Committee 114 of the International Electro-technical Commission (IEC-TC-114) is working to develop a standard for emerging tidal energy conversion systems. The draft standard prescribes methods for determining, objectively and reliably, the scale and character of tidal current energy resources at a site. The IEC-TC-114 draft standard for tidal energy resource assessment and characterisation has not yet been tested in a real world case study. Hence, it is not yet known whether the proposed methods will yield the desired outcome. This research has adopted the Fundy Ocean Research Center for Energy (FORCE) project in Minas Passage, Nova Scotia, for pilot application of the draft standard on tidal current resource assessment. The Bay of Fundy, located on the Atlantic coast of North America between the Canadian provinces of New Brunswick and Nova Scotia, is known for having the highest tidal range in the world and has long been recognised as an ideal stage for tidal energy development. The thesis is presented in three main parts. Firstly, the latest peer-reviewed scientific literature is summarised and the standard is reviewed in view of lessons learned. The aim of this exercise is to establish a scientific basis for and to develop suggestions towards improving and extending future revisions of the standard. Secondly, a comprehensive assessment of the tidal current energy resource at the FORCE project site is conducted in a manner that is consistent with IEC-TC-114 protocol based on available measurements from static current profiler surveys and a two-dimensional hydrodynamic model of the upper Bay of Fundy developed for this study. Thirdly, a sensitivity analysis is performed to determine the main sources of error and uncertainty affecting resource assessment, a topic which has yet to be addressed in the literature.

description: Using the multislit LDSS-2 spectrograph on the William Herschel Telescope we have completed a redshift survey in the magnitude range 22.5 < B < 24 which has produced 73 redshifts representing a 73% complete sample uniformly-selected from four deep fields at high Galactic latitude. The survey extends out to z > 1 and includes the highest redshift galaxy (z = 1.108) yet discovered in a field sample. The median redshift, zmed = 0.46, and form of the redshift distribution constitute compelling evidence against simple luminosity evolution as an explanation of the large excess of faint galaxies (similar or equal to x 2-4 no-evolution) seen in this magnitude range. Rather we identify the excess population as blue objects with z ~ 0.4 and B, luminosities similar to local L* galaxies indicating a dramatic decrease in the density of such objects over the last Hubble time, confirming the trends found in brighter redshift surveys. We also find a marked absence of very low redshift galaxies (z < 0.1) at faint limits, severely constraining any significant steepening of the local field galaxy luminosity function at low luminosities.

description: Declining sea ice area in the Canadian Arctic has gained significant attention with respect to the prospect of increased shipping activities along the Northwest Passage and Arctic Bridge shipping routes. Temporal trend and correlation analysis was performed on sea ice area data for total, first-year ice (FYI), and multi-year ice (MYI), and observed shipping activity within the Vessel Traffic Reporting Arctic Canada Traffic Zone (NORDREG zone) from 1990 to 2012. Relationships between declines in sea ice area and Arctic maritime activity were investigated alongside linkages to warming surface air temperatures (SAT) and an increasing melt season length. Statistically significant increases in vessel traffic were observed on monthly and annual time-scales, coincident with declines in sea ice area. Despite increasing trends, only weak correlations between the variables were identified, suggesting that other non-environmental factors have likely contributed to the observed increase in Arctic shipping activity including tourism demand, community re-supply needs, and resource exploration trends. As a first step towards quantifying spatial variability in shipping patterns, a case study was conducted using 2010 observed shipping data to reconstruct historical shipping routes using a least cost path (LCP) approach. This approach was able to successfully reconstruct vessel tracks compared to an independent data source (Automatic Identification System) to an accuracy of 10.42 km ± 0.67 km over the entire study area. A 25 km gridded product across the entire Canadian Arctic domain was produced for 2010, with this approach now providing a basis to apply this method over the entire record (since 1990) in future studies to investigate long term spatial variability and change of shipping activity across the Canadian Arctic.

description: For the first time in Europe, both European-wide and country-specific levels of urinary Bisphenol A (BPA) were obtained through a harmonized protocol for participant recruitment, sampling and quality controlled biomarker analysis in the frame of the twin projects COPHES and DEMOCOPHES. 674 child-mother pairs were recruited through schools or population registers from six European member states (Belgium, Denmark, Luxembourg, Slovenia, Spain and Sweden). Children (5-12 y) and mothers donated a urine sample. Information on socio-demographic characteristics, life style, dietary habits, and educational level of the parents was provided by mothers. After exclusion of urine samples with creatinine values below 300 mg/L or above 3000 mg/L, 653 children and 639 mothers remained for which BPA was measured. The geometric mean (with 95% confidence intervals) and 90th percentile were calculated for BPA separately in children and in mothers and were named ĄgEuropean reference valuesĄh. After adjustment for confounders (age and creatinine), average exposure values in each country were compared with the mean of the ĄgEuropean reference valuesĄh by means of a weighted analysis of variance. Overall geometric means of all countries (95% CI) adjusted for urinary creatinine, age and gender were 2.04 (1.87-2.24) Ţg/L and 1.88 (1.71-2.07) Ţg/L for children (n=653) and mothers (n=639), respectively. Multiple regression analysis was used to identify significant environmental, geographical, personal or life style related determinants. Consumption of canned food and social class (represented by the highest educational level of the family) were the most important predictors for the urinary levels of BPA in mothers and children. The individual BPA levels in children were significantly correlated with the levels in their mothers (r=0.265, p<0.001), which may suggest a possible common environmental/dietary factor that influences the biomarker level in each pair. Exposure of the general European population was well below the current health-based guidance values and no participant had BPA values higher than the health-based guidance values.Quelle: http://www.sciencedirect.com

Dabei existieren Grenzen nicht in gleicher Weise für alle Menschen. Grenzen, die für eine andere Person existieren, können für die eigene nicht spürbar oder bewusst sein. Ein Beispiel dafür wäre, dass ein Mensch aus dem Globalen Süden meist eine viel eingeschränktere Reisefreiheit besitzt als ein Mensch aus dem Globalen Norden. Dies deutet darauf hin, dass Grenzen nicht für alle Menschen gleichermaßen gelten. Stattdessen sind es kontextgebunde Konstrukte, welche ungleiche Machtverhältnisse in der Welt widerspiegeln. Doch wie entstehen solche Grenzen?

description: This thesis explores the structure and delivery of education programs to justice-involved adults in Canadian federal prisons and in the community. A series of semi-structured interviews as well as three volumes of the Journal for Prisoners on Prisons were analyzed using a qualitative approach to determine whether or not principles of adult education and components of performative space are present in current correctional education strategies. The findings suggest that while there are occurrences of both elements in the education that is provided to prisoners, the programs in the community are much more reflective of these adult learning standards. This project highlights the need for research into the area of adult correctional education, increased collaboration between the fields of criminology and education, and provides a framework from which future research can continue.

description: We study a family of three-dimensional Lie algebras that depend on a continuous parameter. We introduce certain quivers and prove that idempotented versions of the enveloping algebras of the Lie algebras are isomorphic to the path algebras of these quivers modulo certain ideals in the case that the free parameter is rational and non-rational, respectively. We then show how the representation theory of the introduced quivers can be related to the representation theory of quivers of affine type A, and use this relationship to study representations of the family of Lie algebras of interest. In particular, though it is known that this particular family of Lie algebras consists of algebras of wild representation type, we show that if we impose certain restrictions on weight decompositions, we obtain full subcategories of the category of representations that are of finite or tame representation type.

Exploring the Narrative Experience of Somali-Djiboutian Youth In and About Ottawa Public Schools
Creators: name: Farah, Hassan K.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2011

description: This study is an examination into the schooling experiences of an immigrant group of students of Somali-Djiboutian origin who graduated from public schools in Northeastern Ontario over the last two to three years. I show that racialized, visible minority young people face unique barriers and struggles as the intersecting effects of race and class influence their experiences (see also, Desai and Subramanian, 2000; Ibrahim, 2005; Kilbride, Anisef, Baichman-Anisef & Khattar, 2000; Rummens, 2003). Their racialized experiences are central to this study, with special emphasis on how this experience either opens or closes social, material or academic possibilities. Through qualitative research based on interviews, the study explores how young people are able to articulate and negotiate their identities while going through the schooling process. To further investigate this process, I have used an antiracist framework that employs a structural analysis of racism and recognize the contradictory consciousness and consequences that are often involved in the struggle for justice in an inherently competitive and unjust educational system (Henry et & al., 2000; Bannerji, 2000; Dei, 2006, 2005). Through their narratives, participants are able to break the silence and speak out with the aim of illuminating the tensions and contradictions between their experiences in relation to educational policy and actual school practices. The use of interviews reveals perspectives of the participants’ dilemmas that have taken place within the formal and informal educational setting. The research participants were limited to eight graduates from high school in the last two to three years. It is hoped that the completed project may be used by members of the Somali-Djiboutian community to lobby for educational change.

description: Photocatalysis is a green technology that has been widely used in wastewater treatment. In this work, mass transfer processes in corrugated photocatalytic reactors were characterized both experimentally and through computer simulations. For the experimental work, various drum rotational speeds, reactor liquid volumes and number of corrugations were studied to elucidate their effects on mass transfer phenomena. The mass transfer rate was found to increase with increasing rotational speed. Liquid volumes in the reactor significantly affect the mass transfer rate when 20% of the surface area of the drum was immersed. A higher mass transfer rate was found using the drum with 28 corrugations, which had the lowest mass transfer coefficient when compared to the drums with 13 and 16 corrugations. In the computer simulations, velocity and concentration fields within the corrugated reactors were modelled to explore the characteristics of mass transfer processes. The mass transfer coefficients predicted by the simulations were lower than those measured experimentally due to mass transfer limitations occurring between the corrugation volume and bulk solution in the simulations. Based on mass transfer characteristics, it was determined that the drum with 28 corrugations was the most efficient photocatalytic reactor, and had the lowest mass transfer coefficient among those studied.

description: Research Highlights: A set of 128 potential bioenergy facility locations is established and evaluated based on the transport cost to select optimal locations. Background and Objectives: The identification of optimal facility locations to process recovered forest biomass is an important decision in designing a bioenergy supply chain at the strategic planning level. The result of this analysis can affect supply chain costs and the overall efficiency of the network, due to the low density and dispersed nature of forest biomass and the high costs associated with its logistics operations. In this study, we develop a two-stage decision support system to identify the optimal site locations for forest biomass conversion based on biomass availability, transport distance and cost. Materials and Methods: In the first stage, a GIS-based analysis is designed to identify strategic locations of potential bioenergy sites. The second stage evaluates the most cost-effective locations individually using a transportation cost model, based on the results from stage one. The sensitivity of inputs, such as maximum allowable transport cost, the distance of transport and their relations to the profit balance, and changes in fuel price are tested. The method is applied to a real case study in the state of Queensland, Australia. Results and Conclusions: The GIS analysis resulted in 128 strategic candidate locations being suggested for bioenergy conversion sites. The logistics analysis estimated the optimal cost and transportation distance of each one of the locations and ranked them according to the overall performance between capacities of 5 and 100 MW.

description: Network simulations and Markovian queuing models for nodes in isolation have suggested that deflection routing (alternate routing) may be a viable method to resolve wavelength contention. However, we show that deflection routing may destabilise OBS networks operating at high loads. To prevent the destabilising effect of deflection routing, we propose and analyse a technique called wavelength reservation to intentionally limit the amount of deflection at high loads. This paper is the first to present a new reduced load Erlang fixed point analysis of OBS networks with deflection routing and wavelength reservation. We apply the new analysis to evaluate the benefit of deploying deflection routing and wavelength reservation in a sample OBS network.

description: This research presents a pulse-by-pulse analysis of Oscillometric blood pressure waveform at systolic, diastolic and mean arterial pressure points. Using a mathematical optimization technique, pulses are characterized into component harmonic by minimizing the least square error. The results at the important pressure points are analyzed and compared for different subject using different waveform extraction techniques. Blood pressure is estimated using the harmonic parameters. The approach studies changes in the parameters as oscillometric blood pressure recording is done. 8 harmonic parameters are obtained from the pulse characterization and are used to estimate Systolic arterial Blood Pressure, Mean arterial Blood Pressure, and Diastolic arterial Blood Pressure. The estimates are compared with our reference value to determine which has the best agreement. The proposed method is further compared with Maximum Amplitude Algorithm and Pulse Morphology Algorithm. The effect of oscillometric waveform extraction methods on the proposed method is observed. The experiment established the fact that the extraction technique can alter the shape of oscillometric pulses. The methods were compared and it was observed that the used extraction methods did not make any significant difference on the accuracy, using this technique.

description: tRNA genes have the fundamental role of translating the genetic code during protein synthesis. Beyond solely a passive decoding role, the tRNA pool exerts selection pressures on the codon usage of organisms and the viruses that infect them because processing codons read by rare tRNAs can be slow or even erroneous. To better understand the interactions of codons and anticodons in eukaryotic species, we first investigated whether tRNAs packaged into HIV-1 particles may relate to the poor codon usage of HIV-1 genes. By comparing the codon usage of HIV-1 genes with that of its human host, we found that tRNAs decoding poorly adapted codons are overrepresented in HIV-1 virions. Because the affinity of Gag-Pol for all tRNAs is non-specific, HIV packaging is most likely passive and reflects the tRNA pool at the time of viral particle formation. Moreover, differences that we found in the codon usage between early and late genes suggest alterations in the tRNA pool are induced late in viral infection. Next, we tested whether a reduced tRNA anticodon pattern, which was called into question by predicted tRNA datasets, is maintained across eukaryotes. tRNA prediction methods are prone to falsely identifying tRNA-derived repetitive sequences as functional tRNA genes. Thus, we proposed and tested a novel approach to identify falsely predicted tRNA genes using phylogenetics. Phylogenetic analysis removed nearly all the genes deviating from the anticodon pattern, therefore the anticodon pattern is reaffirmed across eukaryotes.
Caring for the living: the conservation of performance art
Creators: name: Magnin, Emilie
Publisher: name: Taylor & Francis
Year: 2023

description: As many disciplines are beginning to reckon with their contributions to historical injustices, so conservation must acknowledge and reflect on the number of its practices that continue to reinforce colonial and imperial legacies. Though such work is currently taking place in ethnographic museums, rethinking conservation and repairing its harms should be the aim of the entire museum community. Using case studies drawn from performance art, this paper demonstrates how performance challenges traditional paradigms of institutional collecting and conservation, and calls for a rethinking of certain museum procedures. It proposes the emerging scholarship on performance art conservation as a potential force for an expanded definition of conservation that puts people at its center. To this end, it presents performance as not only a conservation object to be cared for, but also a tool to care with, reframing the aim of conservation as preserving the vitality of relationships between objects and communities.

description: This thesis examines mothers’ risk perceptions and protective actions as they relate to their children’s environmental health. Children are more exposed and vulnerable than adults to environmental hazards, which have been found to be associated with numerous immediate and long-term negative health outcomes, due to physiological and behavioural factors. Despite the responsibility mothers typically bear as primary caregivers to their children, little is known about how they perceive and negotiate these risks in their day-to-day lives. To better understand mothers’ perceptions and associated protective actions across socioeconomic and geographic contexts, a mixed-method approach was employed involving a quantitative telephone survey (n=606) in Peel Region and Ottawa Public Health Units and qualitative face-to-face interviews (n=15) in Ottawa. Risk perceptions were influenced by income and perceived control, and concerns ranged from chemicals in household products to outdoor air pollution. There was a commonly reported perception that mothers should automatically become more concerned and take protective actions once they have children. When financial or other barriers prevented mothers from taking direct action to reduce risks, such as switching to safer products or changing food habits, they may have relied on emotion-focused coping techniques to reduce feelings of concern, including choosing to ignore risk information. Mothers’ information sources were examined to understand how risk information is best internalized; while the most common source of environmental health risk information was the Internet, many mothers expressed their mistrust in it and would have preferred to receive information directly from healthcare providers. This research contributes to the understanding of risk perception and protective action in a largely understudied population and the findings have practical implications for risk management and communication strategies targeting pregnant women and new mothers.

description: Swinburne University of Technology has six campuses in Melbourne, Australia, one in Thailand and one in Malaysia. The authors of this paper have been responsible for the design, delivery and evaluation of an integrated information literacy and information technology literacy program at the Lilydale Campus in Melbourne for six years. The program forms a large part of Information Methods, a compulsory subject for all first year students, and accounts for 20% of the marks attainable. In 2002 and 2003 each of the authors has served as Information Resources Manager at Swinburne's campus in Malaysia. This campus in Kuching, Sarawak on the island of Borneo is delivering courses identical in content to those undertaken by students in Australia. During their terms as Manager, Julie and Susan provided information literacy skills training for academic staff and students to assist them to meet the same standards of teaching, learning and research as their Australian counterparts. This paper discusses the development of the program over six years at Lilydale and its adaptation for use in an educational environment where English is not the first language of most of the participants and where cultural differences between Australia and an officially Muslim country have to be considered.

Une recension critique des écrits a confirmé une meilleure réussite avec un matériel disponible par rapport à une condition sans matériel sans pour autant expliciter avec finesse la genèse de cette différence. Dans cette recherche doctorale, six élèves d’une classe régulière de troisième année du primaire ont réalisé trois activités de résolution de problèmes arithmétiques verbaux de type additif dans un environnement familier avec des jetons disponibles comme matériel de manipulation. Une analyse de la réalisation de ces activités selon le prisme de la dialectique sujet/matériel a indiqué un rapport pictural ou symbolique de ces élèves avec un matériel autre que les jetons. Une microanalyse de ces activités a mis en relief l’évolution d’un matériel d’une forme plutôt personnelle à une forme plutôt conventionnelle dans la représentation de ces élèves. Cette évolution, souvent non consciente, présente un comportement de ces élèves dans cette activité qualifié d’être en mathématiques. Pourtant, la conscience de cette évolution peut mener à la réussite de la résolution de ces problèmes.

description: The Distal-less homeobox (Dlx) genes encode homeodomain transcription factors found in all animals of the phylum Chordata. These genes are involved in early vertebrate development of limbs, sensory organs, branchial arches and the forebrain (telencephalon and diencephalon). The mouse and human genomes each have six Dlx genes organized into convergently transcribed bigene clusters (Dlx1/2, Dlx3/4 and Dlx5/6). In the forebrain, Dlx1/2 and Dlx5/6 genes play essential roles in GABAergic neuron proliferation, migration and survival. Each bigene cluster includes a short intergenic region (~3.5-16kb) harboring cis-regulatory elements (CREs) that control expression of the Dlx genes. The Dlx1/2 intergenic region harbors the I12b/I12a CREs, while Dlx5/6 includes I56i/I56ii. In determining the regulatory roles of the CREs on Dlx activity and forebrain development, I have characterized the phenotypic changes that occur in mice that have an I56i enhancer deletion. I have also characterized mice with double deletions of I56i and I12b as well as mice that harbored an I12b deletion and have a SNP in the I56i enhancer (vI56i). Mutant mice with a single targeted deletion of I56i are viable, fertile and do not show obvious developmental defects. These mice have significant decreases in Dlx5/6, Gad1/Gad2 and Evf-2 expression in the forebrain and have defects related to GABAergic neuron development. The ΔI56i mutants demonstrate a behavioral phenotype related to anxiety and learning deficits. Mice that lack the I12b enhancer and have the vI56i do not show morphological abnormalities but have severely disrupted Dlx expression. When mice are homozygous for the I56i and I12b enhancer deletion, they do not survive past post natal day 5 and exhibit a dwarfed body size. These mice look weak and seem to have limited motor ability. In characterizing mice with targeted deletions of highly conserved Dlx enhancers, we will have a better understanding of forebrain development.

description: Quivers (directed graphs) and species (a generalization of quivers) as well as their representations play a key role in many areas of mathematics including combinatorics, geometry, and algebra. Their importance is especially apparent in their applications to the representation theory of associative algebras, Lie algebras, and quantum groups. In this thesis, we discuss the most important results in the representation theory of species, such as Dlab and Ringel’s extension of Gabriel’s theorem, which classifies all species of finite and tame representation type. We also explain the link between species and K-species (where K is a field). Namely, we show that the category of K-species can be viewed as a subcategory of the category of species. Furthermore, we prove two results about the structure of the tensor ring of a species containing no oriented cycles that do not appear in the literature. Specifically, we prove that two such species have isomorphic tensor rings if and only if they are isomorphic as “crushed” species, and we show that if K is a perfect field, then the tensor algebra of a K-species tensored with the algebraic closure of K is isomorphic to, or Morita equivalent to, the path algebra of a quiver.

Patient-device associations
Mobile asset management

description: In hospitals and clinics, medical devices incorrectly assigned to patients may cause various patient safety problems. Moreover, the unknown location of required mobile devices (intravenous pumps, cardiac monitors, etc.) represents additional issues for health providers such as unnecessary search effort, delays, and equipment underuse. To mitigate such issues, a patient-device connectivity management system that monitors and tracks patients and their assigned devices becomes an interesting option. Popular approaches for managing associations between patients and devices often involve bar-coding systems, which still require scanning time, are prone to errors, and do not solve equipment location issues. This thesis introduces a new system that exploits Real-Time Location System (RTLS) technology to track patients and devices and support simpler association by a nurse, until disassociation (voluntary or not) happens, at which point the nurse is notified. This system, called Real-time Patient-Device Association and Disassociation (RPDAD), interacts with nurses through their mobile device (tablet or phone). The system provides a new server-based application that interacts with an existing RTLS (hence enabling the reuse of current hospital infrastructure for mobile equipment tracking), a new Android mobile application for nurses, and a novel approach for automated disassociation tracking. The system was validated through proof-of-concept deployments in a university laboratory and in teaching hospital in Ontario, as well as with extensive testing for several configurations in a university laboratory. This thesis discuss-es the feasibility of the approach, its originality compared to the state of the art, and current technological limitations. We expect this system to help avoid usability and disassociation issues while increasing patient care quality and efficiency.

description: Aluminium matrix composites are among the most promising candidate materials for light weight and high strength applications such as transportation and armour. In a previous study 6061 aluminum matrix composites reinforced with plain weave carbon fiber preform (AS4 Hexcel) were successfully fabricated by squeeze casting using the laminate fabrication technique. This research aims at optimizing the fabrication process in order to achieve improved strength and mechanical properties. It focuses on the liquid infiltration squeeze casting method. Good mechanical bonding between fiber and aluminium is achieved thanks to improved infiltration and impregnation of the fabric by liquid aluminium. Oxidation products at fiber/aluminium interface and porosity are reduced. As a result, composites are produced with overall improved mechanical properties. The flexural strength is increased by up to 19.9% and 15.4% compared to the laminate approach and the reference 6061 aluminium alloy squeeze cast under identical conditions, respectively. Similarly, overall hardness is improved. However, the impact strength is reduced by 7.76% and 25.78% when compared to casts fabricated by the laminate method and the reference aluminium alloy, respectively. The thesis constitutes a good basis for further research on fiber and particle reinforced aluminium matrix composites with the goal of further improving fracture toughness, particularly for gradient materials used in armour applications.

Rhodiola Rosea L.- An Evaluation of Safety and Efficacy in the Context of a Neurological Disorder, Alzheimer Disease
Creators: name: Ahmed, Fida Al Noor
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: This thesis examined the safety and efficacy of Rhodiola rosea L. (Crassulaceae), a medicinal plant used traditionally by the Inuit of Nunavik, Québec, for the maintenance of mental and physical health. To assess the effects of Nunavik R. rosea on the central nervous system, a phytochemically characterized extract was tested in behavioural assays of anxiety with rats. Significant changes in behaviour were observed, particularly in the conditioned emotional response test. R. rosea was not a potent modulator of the benzodiazepine site of the GABAA receptor, indicating possible involvement of other neurotransmitters implicated in the neurobiology of anxiety. Safety of Nunavik R. rosea, its marker phytochemicals, and additional R. rosea products was assessed by evaluating the risk of drug interaction potential. Inhibitory capacity was tested on major human drug metabolizing enzymes, the cytochrome P450s. Further, effects on the metabolism of repaglinide, an anti-diabetic drug, were examined in human liver microsomes. While the overall risk of interactions was low, variable impacts of R. rosea products on the formation of glucuronide metabolites of repaglinide necessitate caution. In the TgCRND8 model of Alzheimer disease, R. rosea chronic administration led to modest improvements in the survival of male transgenic mice, which exhibit accelerated rates of mortality. Effects on learning and memory performance in the Morris water maze were limited to alterations in the patterns of use of search strategies as determined by our automated scoring algorithm, MWM Visual; changes in escape latencies were not observed. Nunavik R. rosea administration resulted in elevated plasma levels of anandamide (20:1, n-9), a member of the endocannabinoid family, tentatively identified using an untargeted metabolomics approach via ultra-performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry. R. rosea phytochemicals were either eliminated via the renal pathway, or transformed into potential metabolites. Collectively, the anxiolytic activity of Nunavik R. rosea in rats, its protective effects on high background mortality in an aggressive Alzheimer disease model, low risk of inhibition of major enzymes involved in drug metabolism, and its ability to induce detectable changes in in vivo metabolic pathways are supportive scientific evidence for the use of this traditional medicine for general well-being by the Inuit.

The global mediated experience and/as fictional truth, false intimacy and virtual reality
Creators: name: Arnold, Josie
Publisher: name: Swinburne
Year: 2024

description: This work arises from my teaching online and developing virtual learning communities and from my interest in critical and cultural theories. The ideas I am constructing in this discourse underpin the teaching and thinking I am doing in undergraduate and postgraduate online teaching and learning to virtual communities of students. So this work seeks to practise a non-linear non-scientific performance of knowledge and/as ideas. In doing so it challenges the linearity of much that is accorded traditional ‘research’ status and highlights the enculturisation of knowledge enforced by the perspectives of a dominant masculinist tradition. The paper introduces ideas concerning storytelling as a research process about the teaching of global courses that initiate aspects of fictional truth, false intimacy and virtual reality.
