Pressor response to isometric handgrip combined with foot immersion in cold water.
Creators: name: Liu, Yuning.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Biology, Animal Physiology.

description: The purposes of this study were to (1) compare the pressor response between isometric exercise and a cold pressor test (CPT) and (2) examine the pressor response to isometric exercise at 33% of maximal voluntary contraction (MVC) combined with a CPT applied either at the onset or during the last minute of a 2-min CPT. Ten normotensive male volunteers performed isometric handgrip (HG) at 33% MVC, cold foot immersion, HG combined with a simultaneous CPT, and HG performed during the last minute of a 2-min CPT in a random order over three days. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) were recorded at rest and continuously throughout the tests. The results of this study indicate that (1) the pattern of HR response between the 2-min HG and the CPT was different; (2) DBP values during CPT for the initial 30s and the last 15s were significantly lower than DBP corresponding values during HG, while there were no significant differences between the CPT and HG with respect to SBP response; (3) when HG and CPT were performed simultaneously, the effects on SBP and HR were additive, whereas the effects on DBP and MAP were not; (4) CPT performed for 1 minute prior to HG attenuated the SBP and HR responses to HG at 33% MVC, and (5) although both HR and BP increased in response to HG at 33% MVC, only BP increased progressively in a linear fashion when combined with CPT.

Effects of solute polarization on the hydrodynamics within membrane-fluid-solute systems, with special application to hollow fiber bioreactors.

description: The primary objective of this study was to assess the influence of osmotically active macromolecules on the hydrodynamics of hollow fiber membrane systems which, in turn, influences solute distributions within these bioreactors. This included verifying the phenomenon of concentration polarization of bovine serum albumin (BSA) in a rectilinear flow cell designed to incorporate the salient features of the hollow fiber bioreactor. Following characterization of the membrane used in the study, experimentally determined concentration profiles of BSA were compared with those predicted from theoretical analysis. The membrane characterization revealed local variability in the permeability of the membrane: L$\rm \sb{p}/\mu$ was found to vary between 2.80 $\times$ 10$\sp{-11}$ and 8.19 $\times$ 10$\sp{-11}$ m$\sp2$s/kg. The membrane permeability did not exhibit hysteresis effects due to pressure nor were there substantial changes in the permeability as a result of membrane aging. The permeability of the membrane decreased by approximately 30% following conditioning with a solution of BSA and was successful at retaining the protein. Transient BSA polarization was observed in the extra-luminal space of the rectilinear flow cell after 12, 24 and 36 hours of operation. The theoretical concentration profiles of BSA over predicted the experimental concentration profiles when assuming a membrane permeability equal to the average of the membrane coupon measurements. Further experiments consisted of examining possible dilution of the BSA samples obtained from the flow cell as well as investigating the theoretical assumption of a one-dimensional model. Sedimentation experiments showed that settling of the protein was not responsible for diluting the BSA samples. The local variability in the membrane permeability is thought to contribute to the discrepancy between the theoretical and experimental concentration profiles, as well as transverse concentration gradients not considered by the model.

description: The interaction of gentamicin with daptomycin and PI dispersions was investigated by FTIR spectroscopy. We found no evidence of a direct interaction involving the neutralization of the aspartate residues of daptomycin by gentamicin and the amide I band of daptomycin did not reveal significant conformational changes of its peptidic moiety. On the other hand, daptomycin readily inserts within bilayers of PI, dimyristoylphosphatidylglycerol or dipalmitoylphosphatidylcholine, as judged from its influence on the fluidity of these bilayers. The incorporation of daptomycin into PI bilayers has only a slight effect on the lipopeptide amide I band. The affinity of the aminoglycoside for PI is slightly increased in the presence of daptomycin, in agreement with the results of the dialysis study mentioned above. Gentamicin induces a slight narrowing of the amide I band of daptomycin bound to PI bilayers. The fluidity of the lipid bilayers corresponds to that seen in the absence of both drugs. It is proposed that in the presence of the lipopeptide antibiotic, the critical charge density and membrane fluidity required for optimal enzyme activity is restored, explaining its nephroprotective capabilities. The mechanism of nephroprotection by poly-L-aspartic acid is different from that of daptomycin. Dialysis studies have indicated an optimal binding between gentamicin and polyaspartic acid at acidic pH. We found no evidence of a direct interaction involving the neutralization of the carboxylates of polyaspartic acid by gentamicin and the amide I band of polyaspartic acid did not reveal significant conformational changes. On the other hand, polyaspartic acid had no effect on the spectral features of PI bilayers. A reduction in the changes induced by gentamicin in the lipid head group and interfacial region suggests that the affinity of the aminoglycoside antibiotic decreases in the presence of polyaspartic acid.

description: Cells contain organelles which are dynamic yet coherent structure, but the mechanisms by whichthese assemblies form and stably persist are not well understood. Here, we consider the limiting-poolmechanism which posits that structures grow in a pool of constituents until the pool is depleted. Inorder to study experimental signatures of the limiting-pool mechanism, we construct two simple models: first the self-assembly of two linear filamentous structures, and second of two spherical structures.Using theory and simulations, we analyze the time series of the sizes of the growing structures and makespecific predictions about their autocorrelation functions. We then compare these theoretical results tosynthetic data from stochastic simulations based on the Gillespi algorithm. This approach can be usedin experimental systems to quantitatively test for the limiting-pool mechanism, and can be extended toother size-control mechanisms.
Psychotherapeutic operations and client behavioural commitments.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Psychology, Clinical.

description: Patients' in-session commitments, decisions, or statements of intention to carry out novel behavioural acts between sessions are valued events for many therapeutic approaches. The value or importance of such events is enunciated in the body of psychotherapy theory as well as demonstrated by the results of research. First, the value of behavioural commitments is evident in many theories of psychotherapy, whether this be explicit or implicit. Secondly, research has demonstrated that in-session behavioural commitments are significantly associated with the carrying out of the selected behavioural acts post-session. Despite the importance of behavioural commitments in many systems of psychotherapy, scholars of psychotherapy have pointed out that serious lacunae exist in the specification of therapeutic operations which may be used in catalyzing the occurrence of behavioural commitments. Consequently, it is proposed that the study of therapeutic methods which catalyze such events would constitute a useful avenue of research. An exhaustive review of psychotherapy process research reveals that few research projects have studied the links between psychotherapeutic operations and behavioural commitments. Moreover, the few existing studies suffer from considerable limitations of scope and essentially have failed to identify links between psychotherapeutic operations and behavioural commitments. In order to address this question with a research focus which is appropriate to the current state of knowledge on the matter, the rationale is provided for a qualitative methodology. The aim of the study is to identify psychotherapeutic operations which catalyze "naturally occurring" instances of behavioural commitments identified in psychotherapy session transcripts. Raw data for the study was obtained through an exhaustive search of published transcripts of sessions from a broad array (any and all varieties) of psychotherapies. Products of the study are relevant to the practitioner as practitioner-ready concrete descriptions of behavioural commitment-catalyzing therapeutic operations, and to the researcher as a collection of propositions for further theorizing and research.

Performance evaluation and game theoretic pricing of optimal routing and flow assignment in optical networks

Subjects: subject: Engineering, Electronics and Electrical.

description: Transport service providers need control and optimization strategies for wavelength management, network provisioning, restoration, and protection allowing them to define and deploy new services offers. In this thesis, we apply microeconomic models to investigate the behavior of optical networks in different market environments, and the effect of different pricing schemes in the profitability of optical networks. The routing and wavelengths allocation were modeled using network flows optimization. Network pricing decisions were modeled by applying a game theoretic approach, where the game payoff is the profit of operating the network. We have developed a customer/supplier interaction protocol for network competition control. Two models of competition were introduced. The first model is called "active price competition", allows the customer (wavelength buyer) to interact in order to lower the prices. The second model, is called "passive price competition", assumes that the customer is passive and does not interact with the competitors; the customer accepts the lowest offered price or does not buy even from the lowest bidder if the price is above the buyer's maximum set cost value. In this model, the competitors monitor their own profit and the customer requests success rate to determine their pricing strategy. In both models, we examined different case studies, comparisons and performance evaluations. A mixed integer optimization is employed to determine the wavelengths allocation and flow assignment of the requested customer demand.
Integrated systems analysis for coastal aquaculture

description: This paper presents a model for the evaluation of coastal zone sites in conjunction with supporting decision making on the use of potential sites for aquaculture as well as other site activities including commercial fisheries, and as reserves for natural resources. The decision support model captures site specific data in the form of a geographical information system that overlays selected geographical regions with natural resource dynamics, habitat, commercial activities including aquaculture, and influence plumes including toxicology. Descriptive data for selected regions including system overlays and interactions are then evaluated to provide input to a multicriteria analysis that positions decision makers with respect to the relative importance of resources, habitat, commercial activities, and influence plumes. The model compares alternative evaluations of selected regions among diverse users., as well as providing a group decision evaluation procedure to assist in coastal zonal governance decision makers such as the awarding of fish farm site applications. The model is applied to the coastal zone of Grand Manan Island, New Brunswick situated in the Bay of Fundy.

Multi-channel extracellular recording arrays

description: Carbon fibers are an ideal material for constructing multi-channel extracellular recording arrays. We have been working to construct 16-channel carbon fiber electrodes to record the activity of cells in the ferret LGN. An impedance below 4 MΩ was used as the standard for success. At the start of the process, very few channels met this goal. We implemented new methods for constructing and testing electrodes, and our success rate was brought up to an average of 83% (13 out of 16 channels in 19 electrodes). The new methods include an updated jig design, an improved silver-printing procedure, and the addition of a gold electroplating step to treat the recording tips of the carbon fibers. The electrodes constructed with the revised methods have been used to record from ferret V1 cortex, and have shown recorded spike amplitudes ranging from -150 to -300 µV. These results confirm the capability of our carbon fiber electrodes to record neural activity. Our construction methods provide a solid foundation that equips the lab to make future adjustments to meet the goal of producing electrodes with a higher density of carbon fibers and with the necessary robustness to record in deeper brain regions like the LGN.

description: Attractor networks are a type of dynamical system that evolves to stable activity. Theoretical modeling and experimental observation have both arrived at these networks as a possible mechanism for some brain functions. In this project I use firing rate model units to map out the entire attractor landscape of finite networks with varying structure and connection strength. We then analyse their distribution of attractor basins and entropy. We find that attractor basins are distributed as a power law function of their size in random networks. Furthermore, we find that the properties of this power law evolve to rapidly disfavor small basin sizes as connection strength increases. This pattern allows them to maintain high entropy even when the number of stable states falls drastically. This general power law pattern persists even when introducing small world networks, though we see a peculiar pattern of noise before it is clearly established at high connection.

description: Spinal muscular atrophy (SMA) is an autosomal recessive genetic disease characterized by muscle weakness and atrophy with typical cognition. The first disease-modulating therapy for SMA, nusinersen (brand name Spinraza®), was approved by the FDA in 2016 and has revolutionized management, leading to recommendations for population-wide carrier screening and newborn screening. However, the effects of this drug on prenatal genetic counseling have not been explored. A survey of 182 prenatal genetic counselors (GCs) assessed current knowledge of nusinersen, access to information, and attitudes towards discussing this therapy in practice. Respondent demographics were consistent with the larger NSGC membership as represented in the 2018 Professional Status Survey. The majority of participants (73.6%) knew “a little bit” or “quite a bit” about nusinersen, while 5.5% reported they had never heard of the drug. At an initial screening visit, 15.4% of counselors were “extremely likely” to discuss nusinersen, increasing to 37.0% with one carrier parent, 67.0% with two carrier parents, and 82.2% in the case of a positive prenatal diagnosis. Participants who were more likely to discuss nusinersen had higher baseline knowledge of the drug (p<.05), worked in a setting with access to SMA specialists (p<.05) or nusinersen (p<.05), and perceived this knowledge as highly important for prenatal GCs (p<.05). Only 4.9% of respondents felt that a prenatal genetic counselor was the most appropriate individual to discuss nusinersen with patients, which was lower than expected since these providers often facilitate SMA carrier screening and prenatal diagnosis. In free text comments, several participants noted that a GC would be appropriate to introduce the topic, but then the patient should be referred to an SMA treatment center or prescribing physician to provide more detailed discussion. However, 41.2% of participants were unsure if SMA specialists/treatment centers were available within their region of practice. Additionally, 45.1% of respondents were not sure if nusinersen was offered in their practice setting. Participants unsure if nusinersen was available were less likely to know where to find reliable information (p<.001, χ2 = 29.1) or to feel confident discussing this treatment with patients (p<.01, χ2 = 25.8). Only 12.1% of respondents felt strongly confident discussing nusinersen with patients, but those who did feel confident reported using this knowledge several times per week. As therapies for SMA continue to evolve, there is a need for updated practice guidelines, accessible education and interdisciplinary communication. With these resources, prenatal GCs can provide balanced information and empower patients to make informed decisions about pregnancy management options.

description: Autonomous control of robot vehicles has been studied recently by AI researchers with simulations and implementations emerging using both Neural Networks and Fuzzy Systems. The application is important primarily for autonomous control of planetary surface rovers and deep space vehicles where telepresence control (remote human operator) is precluded because of the long signal transit time. The problem of vehicle docking is specifically addressed in this thesis and the results of experiments on a small model truck and trailer using a mechanical based position sensing systems is reported. Fuzzy logic controls both forward and backward motion of the vehicle to successfully dock the trailer. Additionally, it is shown how the position sensing system can be improved using a small laser-based bar code engine. Future research including use of the system on other mobile robot platforms is discussed and we describe other research planned for the platform. In this thesis the author shows that the use of fuzzy logic for vehicle control simplifies the analysis of motion required to produce proper docking. In particular, the discontinuity of control produced by switching from forward to reverse is readily handled by fuzzy logic.

description: Currently, industrial potato processing waste recycling and re–use is an important topic in the food industry, but no actual processing facilities could be found at the moment of this study. The main aim of present research was to develop a method that could, potentially, be practically applicable for industrial potato peel waste recycling into encapsulated phenolic compounds (fine powder), with a further approbation as an antioxidant for ground pork meat. Potato peel wastes were collected from the local potato processing facility, homogenized in the solvent media, and two accelerated extraction technologies (microwave assisted (MAE) and ultrasound accelerated extractions) were applied for the extraction of biologically active compounds and encapsulation wall material. Produced extracts were concentrated (recovered solvent had been collected and reused) and directed for spray-drying. In general, MAE alone showed higher extraction yields than in combinations with ultrasound treatment. Extracts reached maximal biologically active compound concentrations (and were possessing highest radical scavenging activities) after 10 min of MAE treatment. Produced capsules (food grade antioxidant) inhibited ground pork meat lipid oxidation during the storage study at accelerated oxidation conditions. Acquired results form a basis for development of a potato peel industrial scale processing technology.

description: Real Time Strategy Games (RTSG) are a strong test bed for AI research, particularly on the subject of Unsupervised Learning. They offer a challenging, dynamic environment with complex problems that often have no perfect solutions. Learning Classifier Systems are rule-based machine learning techniques that may rely on Genetic Algorithms to discover a knowledge map used to classify an input space into a set of actions. This work focuses on the use of Accuracy-based Learning Classifier System (XCS) as the learning mechanism for generating adaptive strategies in a Strategy Game. The performance and adaptability of the strategies and tactics developed with the XCS is analyzed by facing these against scripted opponents on an open source game called Wargus. Our results indicate that Genetic Algorithms can be used effectively to enhance Real Time Strategy Games.

description: Lac repressor is a transcription factor that represses expression of genes in the lac operon. The mechanism by which Lac repressor regulates transcription initiation remains unclear, but it is understood that in the presence of Lac repressor, open complex formation is inhibited. In this thesis, we fluorescently label a single-cysteine mutant of the Lac repressor that specifically binds to O1 operator and responds to inducer IPTG in bulk and single molecule in vitro experiments. The labeling efficiency is 26% of monomers, corresponding to 70% of all tetramers in solution having at least one cysteine labeled. The labeled construct, dubbed TAMRA-Lac, was found to be 41% active using an Electrophoretic Mobility Shift Assay. On the single molecule level, the labeled construct binds 57% of operator DNA versus 0.86% of nonoperator DNA and 3.8% of operator DNA after IPTG induction. I used this active and labeled construct in an attempt to probe the mechanism by which Lac repressor regulates transcription initiation on the single molecule level.
Exceptional collections, clusters, $t$-structures, and the relationship between them
Creators: name: Maresca, Raymond Zachary
Publisher: name: Brandeis University
Year: 2024

description: The goal of this thesis is to study exceptional collections of modules over hereditary algebras and their relationship with other popular areas of research. In Chapter 1, we begin by discussing some of the fundamentals of representation theory of finite-dimensional associative algebras. In Chapter 2 we define exceptional sequences and a generalization called exceptional collections. In this chapter, we begin with generalizing a combinatorial model of Garver, Igusa, Matherne, and Ostroff that describes exceptional sequences in type $\mathbb{A}$, to a model that describes exceptional collections in type $\tilde{\mathbb{A}}$. We will use these models to place all exceptional collections in type $\tilde{\mathbb{A}}$ into finitely many families, discuss the algebraic consequences of Dehn twists of these diagrams in terms of the Auslander--Reiten quiver, and count how many families there are for one particular orientation of the quiver. Moreover, we will prove that the notion of relative projectivity and injectivity is well-defined in exceptional collections, and use the models for type $\mathbb{A}$ to classify relative projectivity and injectivity of modules in exceptional collections. In Chapter 3, we will study cluster theory. We will begin by providing a survey of cluster theory through the lens of representation theory. Throughout the survey, we will need the notion of a quiver Grassmannians to explain the coefficients of cluster characters. It is here in Section 3.3 that we will provide a four-fold equivalence of categories between compact Riemann surfaces, fields of transcendence degree one over $\mathbb{C}$, smooth projective curves, and a category of quiver Grassmannians inspired by works of Hille, Huisgen--Zimmermann, Reineke, and Ringel. After, we will study cluster algebras that arise from a surface, where we will compare the combinatorial models introduced in Chapter 2 to study exceptional collections in type $\tilde{\mathbb{A}}$ with the existing models used to study clusters in type $\tilde{\mathbb{A}}$. We will then place clusters in type $\tilde{\mathbb{A}}$ into finitely many families, discuss the algebraic consequences of performing Dehn twists of these diagrams in terms of the cluster category, and count how many families there are for any orientation. Finally, in Chapter 4, we will discuss the relationship between exceptional collections of modules over hereditary algebras and algebraic $t$-structures of the corresponding bounded derived category. In particular, we prove that all such $t$-structures can be attained from exceptional collections of modules by taking appropriate shifts.

description: The influence of bio humus on chemical indicators of the arable layer of soil, productivity and ecological safety indicators of spring wheat of ‘Chelyaba - 75’ variety during the period of 2017–2019 were studied. The object of research was samples of the soil arable layer from the control and experimental field, the structure of wheat yield from control and experimental plots. Bio humus aqueous extract was introduced in the soil of the experimental field before wheat sowing and in the phase of spring tillering at the rate of 10 L/200 L /1 hm2 using the trailer sprayer ‘Zarya’ (Russia) during the dark hours of day. In the study of soil and grain samples, generally accepted methods and techniques were used. It is established that regular chernozems under the conditions of technogenic impact of emissions of thermal power plants are characterized by low humus content (4.58–4.60%) and weak acid reaction of medium (pH = 6.1–6.5); imbalance between biochemically active (copper, zinc, cobalt) and toxic (lead, nickel, cadmium) elements, as confirmed by soil contamination coefficients: for copper (C0 = 1.50–1.58), zinc (C0 = 0.79–0.85). The introduction of bio humus in the tilth top soil before sowing and during tillering of spring wheat contributed to the increase in humus composition by 1.88 times, the change in acidity to pH = 6.9–7.0, reduction of lead and cadmium concentrations in 1.63 and 1.20 times against the background of increased zinc and cobalt levels by 15.62% and 7.98%; increase of field germination of spring wheat from 75.0 ± 0.4 to 82.0 ± 0.9%; quantity of developed stems to be harvested per 1 m2 by 10.15%, productive tilling capacity by 8.33%, average quantity of spikes per ear by 20.00%, average quantity of grain per ear by 7.69%, mass of 1,000 grains by 16.12%, and wheat yield increase by 10.2 hwt ha-1 and decrease in spring wheat grain concentration of lead and cadmium at 14.00 and 16.00%.

description: I have decided to look at leadership transitions in Jewish educational institutions for my Master's thesis. Throughout my time in the Hornstein Program, I have learned about a variety of leadership types. How these leaders can potentially impact an organization is fascinating to me, as over time, they have the power to change an organization's culture, goals, and future. I want to understand how a new leader can influence the educational goals of an organization. What do they prioritize that the past leader did not? What does their background reflect in their leadership style and goals for the organization moving forward? I will answer these questions largely based on my interpretation and the research I have done to learn about cases of leadership transitions in Jewish educational spaces.In the three case studies of leadership transitions that I will describe and analyze, we will see varied types of leadership and different levels of adaptive leadership. How do the organizations and the communities they serve adjust to a new leader? How does the new leader adjust to their role? How will they serve the institution and its educational goals in the future? Leadership transitions can positively or negatively impact an organization, depending on how they are executed. If done well, they can promote future growth and significance of the institution.
Advances in the study of Dientamoeba fragilis.

description: Dientamoeba fragilis is a protozoan parasite first described in 1918. It resides in the human large intestine. D. fragilis has been associated with diarrhoea and abdominal pain in some patients. An indirect fluorescent antibody (IFA) assay was used to examine the presence of D. fragilis trophozoites in preserved faecal specimens. Antiserum to D. fragilis trophozoites was raised in a rabbit with a dixenic culture from the American Type Culture Collection (ATCC 30948). After absorption with Klebsiella pneumoniae and Bacteroides vulgatus, the immune rabbit serum was used for IFA examination. A total of 155 clinical samples were tested: 42 with no parasites, 9 with D. fragilis and 104 with other parasites. The IFA assay detected D. fragilis in 7/9 known positive samples. There were no false-positive IFA readings. Monoclonal antibodies (Mabs) against the parasite was produced in mice and characterized. A MAb (8B2) was obtained against an antigen released when D. fragilis was frozen and thawed. MAb 8B2 reacted with cultured D. fragilis in indirect immunofluorescence but did not react with clinical D. fragilis strains and it did not immunoblot. Another MAb (1H11) was generated against a sodium acetate-acetic acid-formalin fixed antigen. It reacted with D. fragilis isolates in patient specimens and identified a D. fragilis 39kDa protein. Susceptibility testing was performed on D. fragilis ATCC 30948. D. fragilis was cocultured with the bacteria in ATCC medium 1171. The activities of antiparasitic drugs were assessed by counting viable D. fragilis trophozoites with a haemacytometer by trypan blue exclusion. The minimal amoebicidal concentrations of the following four drugs were determined: iodoquinol at 128 $\mu$g/ml, paromomycin at 16 $\mu$g/ml, tetracycline (questionably) at 32 $\mu$g/ml, and metronidazole at 32 $\mu$g/ml. In this seroprevalence study sera from 3 symptomatic patients (F 10 y, M 12 y and F16 y), 12 age and sex-matched controls, and 189 randomly-selected healthy individuals (age range 6 months to 19 years) were tested by an indirect immunofluorescence (IIF) assay for antibodies. All 3 symptomatic patients infected with D. fragilis gave positive IIF titres of 80, and all 12 matched controls were also positive (titre ranges from 20 to 160, geometric mean titer (GMT) was 48). Of the 189 healthy children, 172 (91.0%) were positive at a serum dilution of 1 in 10, or higher. The specificity of the IIF assay was confirmed by immunoblotting 20 representative serum samples against D. fragilis (3 negative and 17 positive sera). All 17 IIF-positive serum samples identified the 39 kDa band, suggesting that this may be an important immunodominant protein of D. fragilis. (Abstract shortened by UMI.)
Preserving the global environment: Compliance with international environment treaties is key.

description: The thesis of this paper is that (1) the successful implementation of international environmental agreements depends on compliance issues in those agreements being effectively addressed; (2) this necessitates compliance issues being addressed both during the initial negotiation of such agreements, and in their subsequent implementation; (3) a number of innovative compliance mechanisms are available which appear to be well-suited to the environmental context, but they may require some refinement. The paper explores the concept of compliance and the theoretical and practical aspects of obtaining compliance with international law. It then utilizes a case study of the Framework Convention on Climate Change to illustrate how the theoretical and practical research described earlier in the paper can be translated into concrete results in environmental treaties. The analysis undertaken in the paper suggests that compliance-related problems are significant in international environment treaties. but not insurmountable. The widest array of compliance techniques possible must be integrated into such treaties--both at the time of their negotiation, and during their implementation--if a sustainable future is to be attained for the planet.

description: This dissertation assesses the role played by Canadian Protestant missionaries in promoting development in Central Angola from 1886 to 1961. It is a case study of the Congregational and United Church of Canada missionaries who worked principally among the Ovimbundu during the heyday of Portuguese colonialism in Africa. The study focuses briefly on the cultural background of the missionaries and the social and scientific advance in the Western world that enabled them to become facilitators of development overseas. This background is contrasted with the more lethargic pace of development in mainland Portugal and its overseas territories. Though distrusted by the Portuguese and African authorities alike at the beginning of their enterprise, the Protestant missionaries were soon welcomed more readily into African villages once it became clear that they could provide African communities with a constructive alternative to the depredations of Portuguese colonialism. By focusing primarily on extractive industries and on plantation economies, the Portuguese State had done very little to promote wholesome development in Angola. Many villagers were forcibly taken from their communities to meet the labour demands of plantations, big companies and public construction projects. The authorities gave little thought to the disruptions that such an exodus caused within individual communities or within the urban districts that did not yet have the facilities to cope with the heavy influx of labourers. To further compound the situation, Portuguese officials tampered with the traditional political structure of African villages, often replacing recognized leaders with their own appointees. Ultimately, they did nothing to preserve the social fabric of Angola and sought, half-heartedly, to replace it with Portuguese traditions. The Protestant missionaries, while seeking primarily to gain Christian converts in Africa, deliberately exposed the Angolans in their mission field to the skills and tools that would enable them to improve their lot under Portuguese domination. Church organization partially replaced the sociopolitical structures that had been weakened or destroyed by Portuguese colonialism. Western education, medical expertise and the application of various agricultural techniques gave the Protestants an advantage that even their Catholic counterparts, ambiguously aligned with the State, did not enjoy. Without seeking to overthrow Portuguese colonialism in Angola, the Protestant missionaries inevitably aided in its downfall by making the Angolans more self-sufficient and keenly aware of their rightful place in the global community.
From Racial Play to Racial Justice: How Historical Relationships Between Black and Jewish Americans Can Inform Experiential Education in Jewish Summer Camps

description: Summer camps are powerful educational tools that have been utilized for decades as socialization enterprises to espouse values that meet an organization’s or individual’s vision of a better future. For many years, those educational tools included the stereotypical portrayal of Native American and Black cultures, in the pursuit of creating ideal American citizens. After World War II, Jewish Americans were situated somewhere in between black and white in the racial matrix that existed in the American consciousness. As Jews sought to integrate into American society and maintain aspects of their religious identity, they created spaces that mirrored those of non-Jewish institutions, providing them with socially relevant experiences within a Jewish context. Black and Jewish Americans shared histories of discrimination and persecution, and both groups respectively faced racism and antisemitism in American society. These shared experiences made Jews a likely partner in the Civil Rights Movement. Yet as Black and Jewish interests began to focus inward, and each group prioritized their own goals separate from the other’s, what was called the Black-Jewish alliance fractured, many asserting beyond the point of repair. This thesis looks at the changing relationship between Black and Jewish Americans during the Civil Rights Movement, the racial and social roots of summer camps, and how those histories inform a path forward for summer camps to begin to play their part in the renewed fight for racial justice.

description: Dans le cadre de la presente these, j'ai tente de vous sensibiliser au role actuel du Commissaire aux langues officielles dans le but avoue de vous presenter d'une part un role futur qui pourrait lui etre attribue et d'autre part de soulever l'interet pour la creation d'un Tribunal sur les langues officielles. Cette etude s'insere dans le contexte sociologique, politique, economique et juridique actuel du Canada. L'idee des modifications proposees au role du Commissaire et celle de la creation d'un Tribunal sur les langues officielles ont pris naissance a la suite d'une prise de conscience des nombreuses insatisfactions exprimees par les citoyens canadiens quant a la difficulte d'obtenir un service dans la langue officielle de leur choix aupres des institutions federales ainsi que des difficultes a travailler dans la langue officielle de leur choix. Il y a donc lieu de replacer les droits linguistiques et la Loi sur les langues officielles dans leur contexte historique. L'objet de la presente these avait pour but de faire le point sur le role du Commissaire aux langues officielles en prenant conscience des limites de ses pouvoirs et en appreciant la situation delicate dans laquelle il exerce ses fonctions afin de faire respecter la Loi.

Recognition of Posed and Spontaneous Dynamic Facial Expressions in Young and Older Adults

description: Theory and past empirical evidence suggest that the use of dynamic, video-recorded facial expression stimuli (as opposed to static, photographed images) may provide additional cues to individuals engaged in emotion recognition tasks and more effectively tap their real-world experience, enhancing their performance. In the context of aging research, the presentation of dynamic stimuli may be of particular benefit to older adults due to their higher levels of accumulated experience relative to younger adult counterparts, although previous evidence of this effect was limited to facial expressions of positive valence. The present study was designed to investigate whether this pattern of findings might extend to a range of facial expressions of emotion. Posed and spontaneous expressions (happiness, sadness, anger, fear, and disgust) produced by older and young adults were video-recorded and, in a separate phase with new participants, shown to older and young adults whose task was to identify the emotions displayed and whether they were posed or spontaneous. Results demonstrated that participants from both age groups were above chance in both elements of the emotion recognition task. However, young adults generally outperformed older adults, with some exceptions in which no age differences were evident, such as in the recognition of happiness and sadness. Additionally, participants as a whole and within each age group showed null levels of response bias (the tendency to decode expressions as posed or spontaneous). Attention to the nature of stimuli used—particularly with respect to the coding of facial muscle movements—is recommended for future research.
Hannah Arendt : de la condition humaine à commencer : exégèse d'un sujet au féminin.

description: Cette these offre une lecture de Condition de l'homme moderne (1961) dans laquelle est articulee la notion arendtienne de l'action comme acte de natalite, du point de vue du commencement de l'etre et de la continuite du monde. Il s'agit d'un travail preparatoire a une reflexion sur le devenir sujet des femmes. A l'aide de l'analyse phenomenologique de Robert Legros (L'idee d'humanite, 1990) et de Paule Levert (L'idee de commencement, 1961), les conceptions rationaliste et romantique du sujet sont synthetisees. La lecture que propose Francoise Collin de la pensee arendtienne permet d'entrevoir comment la question des femmes s'articule au sein des figures emblematiques du politique chez Arendt, dont le statut de citoyen chez les Anciens et la condition de paria chez les modernes. Ces references permettent d'apercevoir chez Arendt deux conceptions du sujet, a la fois antagoniques et complementaires, selon les principes de l'initiation et de la transmission dans l'acte de natalite.
Le choeur: De la conscience collective à la conscience individuelle Exploration de la choralité

description: Cette thèse de création consiste en tine expérimentation sur le choeur à partir d'une pièce intitulée Quitte ou double qui met en scène la conscience d'un personnage entre la vie et la mort. Cette introspection est présentée à la fois par un choeur qui est la conscience---la part abstraite du personnage---et un protagoniste qui représente sa part physique. Le choeur, rompant avec la tradition dramaturgique est ainsi assigné à figurer un individu plutôt qu'une collectivité. La partie théorique dressé les limites de l'expression chorale dans cette perspective tout en s'appuyant stir une recherche historique et dramaturgique portant sur l'évolution des formes chorales en Occident. Elle relève la rareté relative du choeur dans le théâtre contemporain et propose des explications à cette apparente absence tout en ouvrant de nouvelles perspectives quant à sa fonction basées sur un modèle hybride de choeur (entre le choeur antique et la choralité), modèle que met en pratique le texte de création, Quitte ou double.
