description: Avocat de profession, Napoléon-Antoine Belcourt (1860-1932) est une figure bien en vue de l’élite canadienne-française d’Ottawa et de la scène politique fédérale de la fin du XIXe et du début du XXe siècle. Élu en 1896, puis réélu en 1900 et en 1904 député libéral de la circonscription d’Ottawa, Belcourt occupe aussi la fonction de président de la Chambre des communes pendant quelques mois en 1904, avant d’être nommé sénateur en 1907. En 1910, il contribue à la fondation de l’Association canadienne-française d’éducation d’Ontario (ACFEO), dont il occupe la présidence de 1910 à 1912 et de nouveau entre 1921 et 1932. De plus, Belcourt est l’un des chefs de la résistance au Règlement XVII en Ontario. Depuis plusieurs années, l’historiographie de la question nationale et de la question politique au Canada français s’est principalement intéressée à des figures historiques du Québec qui font passer l’intérêt national avant toute chose ou encore à celles qui sont prêtes à accepter des compromis. Pourtant, Belcourt montre qu’il n’est ni l’un, ni l’autre puisqu’il manifeste à la fois sa loyauté partisane, de même qu’un engagement certain à l’égard de la cause canadienne-française. Ce dernier devient toutefois plus important à compter de 1910, au moment où l’homme politique se porte à la défense des intérêts des Franco-Ontariens, alors que ceux-ci ne constituent pas, de toute évidence, un obstacle à sa loyauté partisane. Dans ce contexte, Belcourt affiche un nationalisme modéré qui promeut un Canada fort et uni dans la dualité. Ce faisant, il apporte un discours qui se distingue des acteurs les plus intransigeants de la lutte contre le Règlement XVII et qui ont retenu l’attention des historiens depuis les dernières années. Cette forme de nationalisme, que défend Belcourt au cours de cette période, est aussi défendue par le Parti libéral fédéral à partir des années 1920. L’homme politique est alors un de ceux qui permettent de faire de la question canadienne-française un enjeu au sein de la famille libérale. Ainsi, sa formation politique n’est pas seulement une contrainte pour Belcourt ; elle contribue aussi à façonner son nationalisme.

description: People convicted of sexual offences are arguably one of the most marginalized criminal offender groups because both the general population and offender populations tend to have hardened views of these individuals (Spencer, 2009; Wilson & Prinzo, 2001). Circles of Support and Accountability Ottawa (CoSA-Ottawa) is an organization that helps people convicted of sexual offences reintegrate into society by challenging traditional forms of community reintegration. CoSA-Ottawa was founded on the principles of restorative justice, which are exemplified in their mottos “no more victims” and “no one is disposable.” The organization relies on the commitment and contribution of volunteers to assist with the reintegration process. While there have been various studies on CoSA from different perspectives (Duwe, 2012; Fox, 2014; Wilson, Picheca, and Prinzo, 2007; Wilson & Prinzo, 2001), there have been few studies directly focusing on CoSA-Ottawa volunteers through a critical lens. This study examines the subjective experiences of CoSA-Ottawa volunteers who work with people labeled as ‘sex offenders.’ The research was conducted using semi-structured interviews with six participants. Each interview transcript was transcribed and analyzed using interpretative phenomenological analysis. The master themes that developed through this study include: the humanization of the monstrous, the reintegration and re-socialization through a helping relationship, and overall impacts of these relationships on CoSA-Ottawa volunteers. Using a governmentality and power conceptual framework, this thesis demonstrates how the relationships between the core members and volunteers are transformative and act as an extension of the carceral system. Further, this thesis illustrates that the supportive function of these relationships is explicit, while their governing function is implicit.
Cannabinoids & Stress: The Impact of Endogenous and Exogenous Cannabinoids on Anxiety Behaviors In an Acute Stress Model

Acute Stress

description: Although the impact of cannabinoids (CBs) on anxiety has been thoroughly studied, current research paradigms fail to incorporate acute stressors. The present study investigated the synthetic CB HU-210’s anxiolytic potential in an acute stress CD1 male mouse model, where the animals were subject to a 10-minute Forced Swimming (FS) test between treatment and behavioral tests. Surprisingly, HU-210 did not show anxiolytic action in the Open Field (OFT) and Elevated-Plus Maze (EPM) stressed mice as previously reported in the naïve model literature. The combination of acute stress and high HU-210 doses produced severe locomotor impairments in ambulatory movement that were not previously observed in unstressed mice. It is hypothesized that this anxiogenic phenotype results from the summation of exogenous CB treatment and stress-induced endocannabinoid (eCB) release. Subsequently, the impact of the eCB signaling on anxiety behaviors was examined. Systemic administration of KML29, the selective inhibitor of 2-AG degradative enzyme, returned stress-induced anxiety-like behaviors to baseline levels, without significantly affecting locomotion. KML29’s anxiolyticism was abolished when combined with the cannabinoid receptor antagonist AM281, implying this is a CB receptor-mediated process. A GABAA receptor agonist muscimol was co-administered with KML29 in order to pharmacologically investigate the role of GABAergic neurotransmission in this anxiolytic phenomenon, but it did not alter KML29’s effects. Collectively, these findings suggest that exogenous CBs and acute stress act synergistically in an anxiogenic manner, but that enhanced 2-AG signaling in response to stress demonstrates anxiolytic potential.

description: Gewässersanierungen mit konventionellen Methoden, wie die Entschlammung mit schwerer Technik oder der Einsatz von Chemie zur Wasserreinigung, beeinträchtigen bzw. zerstören Flora und Fauna und verursachen Schäden an Wegen und baulichen Einrichtungen. Gefragt ist eine Gewässerpflege, die auf die speziellen Anforderungen in historischen, denkmalgeschützten Parkanlagen Rücksicht nimmt und schonend mit den natürlichen Ressourcen umgeht. Positive Erfahrungen mit Effektiven Mikroorganismen (EM) veranlasste die gARTenakademie Sachsen-Anhalt ein Projekt zu initiieren, welches sich dem Thema Gewässersanierung mit der EM-Technologie widmet.
Ziel war, Nutzen und Wirkung von Effektiven Mikroorganismen im Sinne einer nachhaltigen Entwicklung gesunder Gewässer modellhaft in zwei historischen Parkanlagen – Zichtau und Aštrioji Kirsna – und vergleichend in zwei europäischen Ländern – Deutschland und Litauen – zu erproben und in ihrer Relevanz für gartendenkmalpflegerische Belange zu untersuchen.

description: Il presente contributo ha l’obiettivo di illustrare un progetto di tesi magistrale che affronta il tema del rapporto tra volontari e i ricercatori che utilizzano la piattaforma BOINC. Il primo capitolo sintetizza cos’è BOINC e i risultati scientifici (oltre 900 pubblicazioni scientifiche in circa 20 anni di attività) dei vari progetti di BOINC. Il secondo capitolo è dedicato alle comunità virtuali che si sono sviluppate, anche in modo complesso, attorno alla piattaforma e il contributo di queste oltre la mera donazione di potenza di calcolo. Il terzo capitolo analizza, attraverso un’indagine campionaria non probabilistica, la principale comunità virtuale italiana di calcolo distribuito su BOINC, ovvero “BOINC.Italy”. Il quarto capitolo approfondisce il rapporto tra i volontari e i ricercatori e il contributo delle imprese private alla piattaforma. Nel quinto capitolo viene commentato il potenziale contributo futuro del calcolo distribuito su BOINC e i limiti delle infrastrutture come EuroHPC. BOINC permette ai ricercatori di utilizzare un’elevata potenza di calcolo con costi ridotti rispetto a un supercomputer. I volontari, oltre a donare potenza di calcolo, svolgono diverse attività: migliorano il codice (dei progetti o di BOINC), traducono i testi dei siti di BOINC, organizzano sfide tra le comunità, partecipano alle fasi di beta-testing dei progetti, reclutano nuovi volontari e utilizzano anche la gamification per aumentare l’interesse verso BOINC. Il rapporto tra volontari e ricercatori è sinergico ed è basato sulla leale collaborazione, infatti se un progetto comunica poco con i volontari molto probabilmente perderà appeal (e potenza di calcolo). La tesi è disponibile sia sul sito dell’Università di Berkeley che a questo link.

Seeking a Respec(table) Environment: A Phenomenological Inquiry into Pre-Service Teachers’ Lived Experience of Anaphylaxis

Eating as a social phenomenon

description: This phenomenological inquiry delved into the lived experience of what it is like to have anaphylaxis, a severe and potentially fatal allergy, for those in the teacher education context. Hence, an understanding of the phenomenon of living with a severe allergy as well as the impact it has on the professional development of teachers emerged. Three pre-service teachers with first-hand experience of anaphylaxis participated in a series of in-depth interviews over the course of five months. Guided by the hermeneutic approach to phenomenological research outlined by Max van Manen as well as the philosophical writings of Bernd Jager on the social experiences of eating, several essential themes surfaced. The lived experience of anaphylaxis can thus be understood through two actions: ‘The Inhale’ which is associated with perceived barriers of anaphylaxis and ‘The Exhale’ which is a sense of relief one experiences when one is managing an anaphylactic allergy. The three most significant contexts where these actions notably hindered or empowered pre-service teachers were: ‘The Habi(table) Environment’, the concept of safe spaces for those with anaphylactic allergies, ‘The Confron(table) Environment’, represented by spaces beyond a safe environment where there is a need to confront the allergy, and ‘The Respec(table) Environment’ which is an inter-subjective space between those with allergies and those without who are able to negotiate their needs with one another, allowing for the creation of respectable community. These themes, comprised of two actions and three contexts, thus serve to offer a sense of what it is like to live with and manage anaphylaxis. They also sensitize educators toward developing thoughtful, pedagogical responses to the increasing rates of anaphylaxis in the classroom.
An Organocatalytic Tethering Strategy: Aldehyde-Catalyzed Cope-type Hydroaminations of Allylic Amines
Creators: name: MacDonald, Melissa
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2014

description: Intermolecular reactions have long been a challenge in organic chemistry due to their high negative entropy and difficult nature, which often includes achieving regioselectivity and stereoselectivity. One strategy that has showed promise in overcoming these obstacles is the use of stoichiometric tethers to effectively temporarily make the reaction an intramolecular system. Therefore in several steps, the formation of a temporary tether, performing the desired reaction, and removal of the tether can enable a selective intermolecular reaction. The clear drawbacks to this method are the several steps required for a single transformation, the inherent waste and reduced overall yield for the synthetic sequence. This work aims at creating a catalytic approach to tethering to by-pass the above limitations and showcase how small organic molecules are effective catalysts’ and can induce asymmetry simply via temporary intramolecularity. The first part of this thesis illustrates this organocatalytic tethering approach via the application of the Cope-type hydroamination of alkenes. The intermolecular reaction of this methodology is extremely difficult and the goal of this work was to create a solution for the harsh conditions and low yields. This chapter describes a proof of concept for our approach using allylic amines and hydroxylamines, and a preliminary look at an asymmetric version of this reaction. The second part of this thesis describes a mechanistic study of our catalytic cycle and provides a detailed look at inhibition and off-cycle pathways. Through this research a second-generation catalyst, formaldehyde, was discovered and an advanced scope is presented. II" The final portion of the thesis focuses on an enantioselective and diastereoselective Cope-type hydroamination of alkenes via the organocatalytic tethering strategy. Optimization and substrate scope are presented, along with a discussion of the origins of selectivity. Derivatization of the final products is explored and future applications of the strategy are discussed.
Control of Ignition Temperature in Hybrid Thermite-Intermetallic Reactive Systems

description: Thermite compounds have received a renewed interest due to their ability to store large quantities of energy that is comparable to conventional energetic materials. Such reactive materials can be manipulated to create a nanolaminated structure. It has been shown that an increase in the fraction of nanolaminated particles can reduce the ignition temperature and increase reactivity. In the present study, methods to lower the ignition temperature of aluminium copper-oxide (Al-CuO) are assessed. Arrested reactive milling (ARM) was used on stoichiometric Al-CuO powders to increase the nanolamination and reduce the ignition temperature to 840 Kelvins (K). Milling alone not only reduced the ignition temperature slightly, but for milling times greater than 30 minutes, intermediate phases were produced, which had negative impacts on the reaction characteristics. Another method to reduce the ignition temperature of Al-CuO involved creating a hybrid mixture using a compound with a lower ignition temperature to further decrease the ignition temperature of Al-CuO. ARM was used to lower the ignition temperature of a nickel aluminium (Ni-Al) intermetallic compound down to 480 K. Hybrid mixtures were then created with varying concentrations of milled and unmilled Al-CuO-Ni. Powders were then tested in a tubular furnace to determine the ignition temperature dependence on heating rate and concentration of constituents. It has been shown that an unmilled hybrid mixture with 75% and 50% concentration of Al-CuO has an ignition temperature of 840 K. Higher concentrations of Ni-Al resulted in lowered ignition temperatures which varied between 600 K and 480 K. A milled hybrid mixture has lower ignition temperatures than an unmilled mixture. It was shown that a milled hybrid mixture with a 75% concentration of Al-CuO has an ignition temperature of 840 K, corresponding to pure Al-CuO. The ignition temperature of the milled hybrid mixture was reduced to approximately 520-620 K for concentrations of Ni-Al of 50%, and 473-573 K for concentrations of 75% Ni-Al.

description: By 2050, the European Union aims to become climate neutral. The achievement of this goal will require, among others, a massive boost in energy efficiency. Companies and other organizations can make a significant contribution to climate protection through systematic and long-term energy management. Since its publication in 2011, ISO 50001 became the most important international standard for energy management systems. The guide “energy management systems in practice” contains instructions, recommendation and practical examples that support organizations in implementing an energy management system according to ISO 50001:2018 based on an initial energy audit. For companies and organizations that initially want to assess if an energy management system is worthwhile, the guide contains a “test run“ which can be carried out with manageable effort. For those companies and organizations that want to go beyond energy management and address their environmental impacts comprehensively, the guide explains how to step up to ⁠EMAS⁠, the eco management and audit scheme of the European Union.

description: Crossing the Cartography of Exile explores ideas of territoriality, hybrid identity and transculturation. The thesis and exhibition is the result of two years of Practice-Led Research, which is the performative research methodology, carried in the La Chapelle Woodshop of the 100 Laurier Avenue East Building of the Department of Visual Arts. The building was the former Juniorat du Sacré-Coeur of the Oblates of Mary Immaculate built in 1893-94. The Woodshop is the former chapel of the seminary therefore has references to a place of prayer and worship and for my praxis became a place to re-enact the ancient trade of Joseph the Carpenter. The La Chapelle Shipyard inside the woodshop as mnemonic site became a performative site-specific platform specialized in creating small-scale sculptures with recycled and repourposed shipping pallets and a place in which to connect memory with the ancient trade of a shipwright or shipbuilder. Small-scale sculpture then became a symbolic marker for the intimacy of a personal and free territory made of repurposed shipping pallets. Therefore, by working with recycled changeable materials I fashioned a poetic visual language to enchant the wound of exile.

Pftaire1 (Cyclin Dependent Kinase14): Role and Function in Axonal Outgrowth During the development of the CNS

Subjects: Axon-Cdk14-GTPase

description: Cyclin Dependent Kinase (Cdk) family members play a role in CNS development. Cyclin Dependent Kinase 5 (Cdk5) is well known for its fundamental role in neuronal development and axogenesis, as well as, cell death. Other Cdks include Pctaire and Pftaire. Inhibition of Pctaire results in increased axon outgrowth, however, the role and function of Pftaire is unknown. Pftaire1 is a novel member of the Cdk family that was initially detected in a screen for cdc2-like kinases. Unpublished data from our lab reveals that Pftaire1 (Eip63E) deficiency in Drosophila melanogaster results in defects in the axon and neuronal structure of the ventral nerve cord (VNC). In mammals, Pftaire1 is highly, expressed in the CNS. Here, we proposed that Pftaire1 might have a role in axon outgrowth. To investigate the role of Pftaire1 in mammals, the first germline Pftaire1 knockout mice were generated. Considering the severe effects of Eip63E deficiency in Drosophila and the homology between mammalian and fly Pftaire1, CNS defects in the mouse were anticipated. However, to date, no gross abnormalities have been detected in the overall morphology, fertility, life span, or anatomical brain structures of the Pftaire1 deficient mice. This may be due to the presence of other post-mitotic Cdk proteins that are highly similar to Pftaire1. For instance, mammals possess Pftaire (1, and 2), as well as, Pctaire (1, 2, and 3), while Drosophila only possess the Pftaire1 orthologue where the Pftaire2 and Pctaire (1, 2, and 3) are absent. Furthermore, the mice were of mixed background. In spite of this, we demonstrated that Pftaire1 deficient neurons showed increased axon length, in the initial phases of culture. This was confirmed by expression of dominant negative (DN) D228N-Pftaire1 in wild type neurons. Also classification of axons into different ranges, reveals a higher percentage of hyperextended neurites in D228N and Pftaire1 knockout mice. The mechanism by which Pftaire1 controls axon outgrowth is unknown. In this study we show that, Pftaire1 interacts physically with the small GTPase proteins Rac1, Cdc42, and RhoA. Importantly, we showed that Pftaire1 phosphorylates GDP-RhoA on a serine residue. We propose that this regulates RhoA activity, which in turn controls axon outgrowth.

Buckling Analysis of Steel Plates Reinforced with GFRP
Creators: name: Zaghian, Sepideh
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: Glass Fiber Reinforced Polymers (GFRP) plates have recently received attention as a viable option for reinforcing existing steel members. Possible application involve web strengthening of existing plate girders and reinforcing corroded flanges and/or webs where a steel plate under combination of shear and/or normal stresses can be governed by their buckling strength. Using GFRP as a retrofit material is attractive from several respects such as easy application, achieving high additional strength with low additional weight, and corrosion resistance. Since the elastic properties of the GFRP, adhesive, and steel are orders of magnitudes apart, reliable predictions of the buckling strength of such systems necessitates careful 3D modelling involving significant modelling and computational effort. Within this context, the present study develops a simplified buckling theory for steel plates symmetrically reinforced with GFRP plates and subjected to in-plane biaxial normal stresses and shear. The theory idealizes the steel and GFRP as Kirchoff plates while accounting for the transverse shear deformations within the adhesive layers. A variational formulation is first developed based on the principle of stationary potential energy. The validity of the variational formulation is then assessed through systematic comparisons with results based 3D finite element models for a variety of buckling problems. The variational principle thus validated, is then used to develop a finite element formulation. The new element features four nodes with five degrees of freedom per node. Results based on the finite element are compared to results based on 3D modelling to assess its validity. The element is then used to investigate the effect of GFRP thickness, adhesive thickness, and adhesive shear modulus on the critical pressure of composite systems for practical retrofitting problems. It is shown that GFRP thickness is particularly effective in increasing the capacity of the composite system, while the effect of the adhesive layer shear modulus low to moderate. Conversely, an increase in the adhesive thickness is found to correspond to a decrease in buckling capacity of the composite system.
Examination of the Regulation of Biofilm-Specific Antibiotic Resistance Genes in Pseudomonas Aeruginosa
Creators: name: Nadeau, Jean-Paul
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2013

description: Upon contact with a surface, the bacterium Pseudomonas aeruginosa forms a bacterial community encased in an exopolysaccaride matrix. One difference between this structure, known as a biofilm, and free-swimming cells is its ability to be 10 to 1,000 times more resistant to antibiotics. This increased resistance is partially due to the presence of six biofilm-specific antibiotic resistance genes. Three of these genes, ndvB, PA1874-77 and tssC1 have been characterized in terms of their role in antibiotic resistance, while the other three have not been fully characterized. However, all six genes are more highly expressed in biofilm cells as compared to planktonic cells and contribute to a biofilm-specific antibiotic resistance phenotype. Previous in silico analysis found a 22 base pair consensus sequence upstream in the promoters of all six biofilm-specific antibiotic resistance genes. It is hypothesized that this motif controls the biofilm-specific expression of these genes. Results from a DNA-affinity chromatography experiment suggest that several proteins from a biofilm extract bound the 22bp motif of ndvB and PA1874-77. However, one major band was consistently binding the 22bp motif. It is predicted that the regulatory protein that binds to the 22bp motif will play a prominent role in conferring a biofilm-specific antibiotic resistance phenotype. This protein was identified as a putative transcriptional regulator. Further experimentation using this protein in the binding reaction found that this interaction may not be specific to the 22bp motif and further investigation is warranted. A second separate but related research goal was to analyze temporal expression of ndvB using promoter-fluorescent protein constructs. The reason for this study was to examine the effects of heterogeneity within biofilms on expression of biofilm-specific antibiotic resistance genes. Using fluorescence microscopy it was found that planktonically, ndvB begins to be expressed at an OD600 of 2.0, an OD600 that corresponds to early stationary phase. In biofilms ndvB expression begins following monolayer formation. These initial discoveries have highlighted the usefulness of this experimental system and laid the groundwork for a more comprehensive study of spatial and temporal expression of all six biofilm-specific antibiotic resistance genes in Pseudomonas aeruginosa.
Harms of public health interventions against covid-19 must not be ignored

description: The SARS-CoV-2 pandemic has posed an unprecedented challenge for governments. Questions regarding the most effective interventions to reduce the spread of the virus—for example, more testing, requirements to wear face masks, and stricter and longer lockdowns—become widely discussed in the popular and scientific press, informed largely by models that aimed to predict the health benefits of proposed interventions. Central to all these studies is recognition that inaction, or delayed action, will put millions of people unnecessarily at risk of serious illness or death. However, interventions to limit the spread of the coronavirus also carry negative health effects, which have yet to be considered systematically. Despite increasing evidence on the unintended, adverse effects of public health interventions such as social distancing and lockdown measures, there are few signs that policy decisions are being informed by a serious assessment and weighing of their harms on health. Instead, much of the discussion has become politicised, especially in the US, where President Trump’s provocative statements sparked debates along party lines about the necessity for policies to control covid-19. This politicisation, often fuelled by misinformation, has distracted from a much needed dispassionate discussion on the harms and benefits of potential public health measures against covid-19.

description: Condensation in linear wedges formed by semi-infinite walls is a well-established critical phenomenon characterized by the continuous growth of an adsorbed liquid layer as bulk two-phase coexistence is approached. In this study, we investigate condensation in finite-length wedges open at both ends, demonstrating that the process becomes first-order. The open boundaries and finite geometry induce a remarkably rich phase behavior of the confined fluid, exhibiting three distinct types of condensation, reentrant phenomena, and continuous higher-order transitions between condensation states. Through a detailed macroscopic analysis, we derive the conditions for each type of condensation, classify the global phase diagrams, and explore asymptotic behavior in specific limiting cases. The asymptotic predictions are confirmed by a detailed comparison with the numerical solutions of the governing equations.
Adsorption Separation of CO2 from CO in Syngas: Improving the Conversion of the Reverse Water Gas Shift Reaction

description: In this research project, adsorption is considered for the separation of CO2 from CO for applications such as industrial syngas production and in particular to improve the conversion of the Reverse Water Gas Shift (RWGS) process. The use of adsorption technology for these applications requires an adsorbent that can effectively separate out CO2 from a gas mixture containing CO2, CO, and H2. However, adsorption of H2 is insignificant when compared to both CO2 and CO, with only CO2 and CO being the adsorbed species. The adsorption of CO2 and CO was investigated in this work for four major types of industrial adsorbents which include: activated aluminas, activated carbons, silica gels, and zeolites. Zeolites, with their ability to be fine tuned many parameters which may affect adsorption, were investigated in terms of the effect of the cations present, SiO2/Al2O3 ratios, and structure to determine how to optimize adsorption of CO2 while decreasing adsorption of CO. This will help to determine a promising adsorbent for this separation with focus on maximizing the selective adsorption of CO2 over CO. To investigate this separation three scientific experimental methods were used; gravimetric adsorption isotherm analysis, volumetric adsorption isotherm analysis, and packed bed adsorption desorption breakthrough analysis. Gravimetric and volumetric methods allow for testing the adsorbent with the individual species of CO2 and CO. This investigation will let us determine the pure component adsorption capacity, heats of adsorption, regenerability, and basic selectivity. Packed bed adsorption breakthrough experimentation was then carried out on promising adsorbents for the CO2 separation from a mixture of CO2, CO, and H2. These experiments used a gas mixture that would be comparable to that produced from the RWGS reaction to determine the multicomponent gas mixture behaviour for adsorption. Temperature swing adsorption (TSA) with a purge gas stream of H2 was then used to regenerate the adsorbent.

Methods: These studies used both a stacked cross-sectional and a trajectory/latent class analysis design Univariate and multivariate multinomial logistic regressions were used to assess the relationship between physical and sedentary activity and depression using the emotional disorder-anxiety scale for children and youth available in the NLSCY. Results: When accounting for covariates, physically inactive respondents had increased odds of higher depressive symptom scores. Sedentary activity was only statistically significantly associated with depressive symptoms in the cross-sectional design. Conclusions: Physical inactivity is significantly associated to depressive symptomatology. The relationship between sedentary activity and depression is inconclusive.

description: Recent studies suggest a possible correlated evolution of wing morphology, wing beat frequency, muscle biochemistry and flight metabolic rate in bees. In order to investigate the degree to which natural selection can act on these traits, an estimation of heritability was required. Commercial and laboratory reared colonies from wild caught queens were used to estimate narrow-sense (h2) and broad-sense (H2) heritability of flight metabolic rate and its associated traits in the bumblebee Bombus impatiens. h2 estimates obtained from parent-offspring regressions were not statistically significant. H2 estimates were significant for morphological traits (body mass and wing morphology) as well as whole-animal traits (flight and resting metabolic rate, wing beat frequency) in both populations. We suggest that queens have a decrease in flight performance as a result of a trade-off between flight and fecundity, explaining the lack of significance in parent-offspring regressions.
A Journey Through Wanderweg: the Cinematic Space of Deleuze and Guattari in the Reflexive Road Movie
Creators: name: Paluzzi, Nicholas
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2013

description: This paper addresses a modern trend within the road movie genre, where reflexive imagery is utilized as a mechanism of storytelling. Within the “reflexive road movie,” the reflexive space and the road movie space are cinematically contrastive to each other. The road movie provides a cinematic space for the protagonist to explore cultural, societal, and personal boundaries, perpetually moving towards an unreachable horizon. Reflexivity, on the other hand, consistently reminds the viewers of the technical and conceptual means of production, forcing the viewer (and the film itself) to reference its own borders and form. Thus, reflexivity obstructs the traditional motion within the road movie space. In order to conceptualize this claim, this thesis appears in two parts: the theoretical and the artistic. Theoretically, this study draws from Deleuze and Guattari’s concepts of (de)territorialization and Deleuze’s movement-image and time-image. Artistically, this study references an original film, titled Wanderweg (2013), which was created as a means of visually illustrating the theoretical conclusions of this study. Together, the theoretical and artistic components of this thesis examine how reflexivity spatially positions itself within a road movie.

description: Cette étude fait l’examen historique du processus de structuration pédagogique opéré par les membres du milieu associatif franco-ontarien se chargeant des écoles bilingues entre 1927 et 1960. En se fiant aux actions menées et aux discours formulés par deux des principales tribunes éducatives de l’Ontario français, l’Association canadienne-française d’Éducation d’Ontario (ACFEO) et l’Association d’enseignement français en Ontario (AEFO), elle vise à tâter la nature du projet scolaire que ces associations négocièrent auprès des autorités scolaires ontariennes. Elle analyse les repères thématiques de l’enseignement du français et de l’histoire à partir de la sphère discursive au sein de laquelle ils furent discutés. En suivant cette grille méthodologique, l’étude fait ressortir le procédé de modernisation de la pédagogie franco-ontarienne par la fondation d’un lieu professionnel où elle serait comprise par ses responsables comme la recherche d’un équilibre amalgamant idéaux nouveaux et héritage culturel. Cette thèse met en images la formulation historique d’un équilibre particulier alliant aux impératifs démocratiques le legs d’une tradition.
Tricolore: Multi-Behavior User Profiling for Enhanced Candidate Generation in Recommender Systems

description: Online platforms aggregate extensive user feedback across diverse behaviors, providing a rich source for enhancing user engagement. Traditional recommender systems, however, typically optimize for a single target behavior and represent user preferences with a single vector, limiting their ability to handle multiple important behaviors or optimization objectives. This conventional approach also struggles to capture the full spectrum of user interests, resulting in a narrow item pool during candidate generation. To address these limitations, we present Tricolore, a versatile multi-vector learning framework that uncovers connections between different behavior types for more robust candidate generation. Tricolore's adaptive multi-task structure is also customizable to specific platform needs. To manage the variability in sparsity across behavior types, we incorporate a behavior-wise multi-view fusion module that dynamically enhances learning. Moreover, a popularity-balanced strategy ensures the recommendation list balances accuracy with item popularity, fostering diversity and improving overall performance. Extensive experiments on public datasets demonstrate Tricolore's effectiveness across various recommendation scenarios, from short video platforms to e-commerce. By leveraging a shared base embedding strategy, Tricolore also significantly improves the performance for cold-start users.

description: This qualitative study explores how youth in Tanzania, with low levels of basic education, manage their personal lives and seek opportunities in the workplace or in post-basic education training programs. In Tanzania, Education for All (EFA) has served as a key focal point of coordination between the government and the international donor community. While substantial attention has centered on the challenges of ensuring the sustainability and quality of EFA, there is relatively little known about the socio-economic circumstances of young school leavers and their perceptions of education and its relation to their post-school life trajectories. Using structuration theory as the theoretical framework to illuminate the dynamic interconnectedness of social structures and youth agency, I conducted semi-structured interviews with 14 young male and female school leavers. Disturbing patterns of social reproduction and a fundamental discontinuity between basic education and post-school challenges were revealed in the research. Yet, in view of their resilience, orientation to the future and entrepreneurial resourcefulness, findings suggest that despite profound qualitative shortcomings, aspects of basic education and the structuring effects of economic liberalization may be contributing to enhanced youth agency. The dissertation contributes to the theoretical discourse in the study of youth phenomena by adapting and advancing Klocker’s (2007) use of the notion of thinners and thickeners of agency within structuration theory. Exploring factors like educational quality and attainment level, in addition to those already established by Klocker (tribe, gender, age, and poverty), my research shows how young people’s agency can be attenuated or accentuated in space and time. This dissertation contributes empirical, hermeneutic and narrative data to illuminate the educational experience and post-basic education realities for a group of Tanzanian youth, reducing what has heretofore been described as a paucity of such qualitative accounts of marginalized African youth and the challenges they face.
