"Once you win their hearts and minds, what are you going to do with it?" : exploring the cultural repertoires of elementary school teachers in France and Canada.

description: Although education is heralded as a national priority in France and Canada, previous research has suggested that the experience of schooling is very different in both countries. This can be noticed as early as elementary school, where teachers in both countries work towards similar goals of literacy, but with different techniques and conceptual tools. Drawing on classroom observations and thirty-five interviews with elementary school teachers in France and Canada, this study explores the way that educators talk about their roles, responsibilities and everyday practices to illustrate how their discourses are shaped by the national educational repertoires available to teachers. Through focusing on the contrasting ideologies of social pluralism that are multiculturalism and républicanisme (in Canada and France respectively), this research illuminates in particular the influence that national projects of diversity have over teachers’ discourses and practices when it comes to conceptualizing the role that diversity can play in the classroom. This difference in how diversity is imagined closely interacts with differing ideas about effective teacher techniques to create dissimilar learning environments in France and in Canada in terms of the teacher-student relationship, classroom space, and the value of student diversity.

description: Within gauge/gravity duality, we construct a backreacted supergravity background dual to SU(Nc) N=4 SYM coupled to Nf massive fundamental flavours in the presence of an external magnetic field. Our solution is perturbative in a parameter that counts the number of the internal flavour loops. The background has a hollow cavity in the bulk of the geometry, where it is similar to the supergravity dual of a non-commutative SYM. The radius of this cavity is related to the dynamically generated mass of the fundamental fields. We apply our construction to study the effect of magnetic catalysis and develop an appropriate renormalization scheme to compute the free energy and the fundamental condensate of the dual gauge theory as a function of the bare mass. While at leading order in the expansion of the perturbative parameter, the free energy and the fundamental condensate agree with the results obtained in the quenched approximation, at next order we show that the effect of magnetic catalysis is enhanced and the contribution to the condensate of the theory from internal fundamental loops runs logarithmically with the finite cutoff Lambda_UV.

title: Computer assisted design of experiments

description: It is now generally true that the computer is widely used for analysing data from comparative experiments but relatively little attention has been paid to how the computer can assist at the design stage of an experiment. This thesis attempts to remedy this situation. In Chapter 1 an attempt is made to formalize the conversation that takes place between an experimenter and a statistical consultant with a view to transferring the consultant's skills to the computer. To determine the difficulties involved experiments to compare two treatment means are considered. Where there are more than two treatments it is essential to determine which treatment comparisons are important. Existing computerised algorithms for constructing suitable experimental designs deal solely with the case where there is an equal interest in all treatment comparisons and where all blocks are of the same size. Chapter 2 describes an algorithm without these limitations. It searches for treatment interchanges that improve a given design. In Chapter 3 this algorithm is extended to cover row- and-column designs. A further algorithm is required to combine component designs. One disadvantage of these algorithms is the invariance of the treatment replications once chosen. In Chapter 4 completely different algorithms without this disadvantage are developed. They are based on an exchange procedure and an interchange procedure.

description: We report on the observation of the confinement-induced collapse dynamics of a dipolar Bose-Einstein condensate (dBEC) in a one-dimensional optical lattice. We show that for a fixed interaction strength the collapse can be initiated in-trap by lowering the lattice depth below a critical value. Moreover, a stable dBEC in the lattice may become unstable during the time-of-flight dynamics upon release, due to the combined effect of the anisotropy of the dipolar interactions and inter-site coherence in the lattice.

description: We study various holographic RG flow solutions involving warped asymptotically locally Euclidean (ALE) spaces of $A_{N-1}$ type. A two-dimensional RG flow from a UV (2,0) CFT to a (4,0) CFT in the IR is found in the context of (1,0) six dimensional supergravity, interpolating between $AdS_3\times S^3/\mathbb{Z}_N$ and $AdS_3\times S^3$ geometries. We also find solutions involving non trivial gauge fields in the form of SU(2) Yang-Mills instantons on ALE spaces. Both flows are of vev type, driven by a vacuum expectation value of a marginal operator. RG flows in four dimensional field theories are studied in the type IIB and type I$'$ context. In type IIB theory, the flow interpolates between $AdS_5\times S^5/\mathbb{Z}_N$ and $AdS_5\times S^5$ geometries. The field theory interpretation is that of an N=2 $SU(n)^N$ quiver gauge theory flowing to N=4 SU(n) gauge theory. In type I$'$ theory the solution describes an RG flow from N=2 quiver gauge theory with a product gauge group to N=2 gauge theory in the IR, with gauge group $USp(n)$. The corresponding geometries are $AdS_5\times S^5/(\mathbb{Z}_N\times \mathbb{Z}_2)$ and $AdS_5\times S^5/\mathbb{Z}_2$, respectively. We also explore more general RG flows, in which both the UV and IR CFTs are N=2 quiver gauge theories and the corresponding geometries are $AdS_5\times S^5/(\mathbb{Z}_N\times \mathbb{Z}_2)$ and $AdS_5\times S^5/(\mathbb{Z}_M\times \mathbb{Z}_2)$. Finally, we discuss the matching between the geometric and field theoretic pictures of the flows.

description: We present relative positions of visual binaries observed during 2009 with the FastCam "lucky-imaging" camera at the 1.5-m Carlos Sanchez Telescope (TCS) at the Observatorio del Teide. We obtained 424 CCD observations (averaged in 198 mean relative positions) of 157 binaries with angular separations in the range 0.14-15.40", with a median separation of 0.51". For a given system, each CCD image represents the sum of the best 10-25% images from 1000-5000 short-exposure frames. Derived internal errors were 7 mas in r and 1.2^{\circ} (9 mas) in q. When comparing to systems with very well-known orbits, we find that the rms deviation in r residuals is 23 mas, while the rms deviation in q residuals is 0.73 deg/r. We confirmed 18 Hipparcos binaries and we report new companions to BVD 36 A and J 621 B. For binaries with preliminary orbital parameters, the relative radial velocity was estimated as well. We also present four new revised orbits computed for LDS 873, BU 627 A-BC, BU 628 and HO 197 AB. This work is the first results on visual binaries using the FastCam lucky-imaging camera.

description: Nephrogenesis in the human ends by the 36th week of gestation. In premature infants, nephrogenesis is assumed to continue after birth. Indomethacin (NSAID) is commonly used to treat patent ductus arteriosus (PDA) in premature infants. We hypothesized that administration of indomethacin in the newborn rats would cause a reduction in glomerular number. Four dosegroups of rats (n=7 in each) were injected intraperitoneally with three different doses (0.1, 0.5, 1 mg/kg) of indomethacin or a saline control for 11 days after birth. At the endpoint, blood was collected to measure indomethacin plasma concentrations and kidneys were collected for morphological measurement. Stereological techniques were used to measure the glomerular number and volume in these animals. We observed no significant differences in glomerular number (p=0.39) and volume (p=0.98) between the different treated groups. In conclusion, administration of indomethacin, while the process of nephrogenesis is ongoing, does not significantly reduce/change the glomerular number.

description: We report the first tungsten isotopic measurements in stardust silicon carbide (SiC) grains recovered from the Murchison carbonaceous chondrite. The isotopes 182W, 183W, 184W, 186W and 179Hf, 180Hf were measured on both an aggregate (KJB fraction) and single stardust SiC grains (LS+LU fraction) believed to have condensed in the outflows of low-mass carbon-rich asymptotic giant branch (AGB) stars with close-to-solar metallicity. The SiC aggregate shows small deviations from terrestrial (=solar) composition in the 182W/184W and 183W/184W ratios, with deficits in 182W and 183W with respect to 184W. The 186W/184W ratio, however, shows no apparent deviation from the solar value. Tungsten isotopic measurements in single mainstream stardust SiC grains revealed lower than solar 182W/184W, 183W/184W, and 186W/184W ratios. We have compared the SiC data with theoretical predictions of the evolution of W isotopic ratios in the envelopes of AGB stars. These ratios are affected by the slow neutron-capture process and match the SiC data regarding their 182W/184W, 183W/184W, and 179Hf/180Hf isotopic compositions, although a small adjustment in the s-process production of 183W is needed in order to have a better agreement between the SiC data and model predictions. The models cannot explain the 186W/184W ratios observed in the SiC grains, even when the current 185W neutron-capture cross section is increased by a factor of two. Further study is required to better assess how model uncertainties (e.g., the formation of the 13C neutron source, the mass-loss law, the modelling of the third dredge-up, and the efficiency of the 22Ne neutron source) may affect current s-process predictions.

description: Because organisms synthesize component molecules at rates that reflect those molecules' adaptive utility, we expect a population of biota to leave a distinctive chemical signature on their environment that is anomalous given the local (abiotic) chemistry. We observe the same effect in the distribution of computer instructions used by an evolving population of digital organisms, and characterize the robustness of the evolved signature with respect to a number of different changes in the system's physics. The observed instruction abundance anomaly has features that are consistent over a large number of evolutionary trials and alterations in system parameters, which makes it a candidate for a non-Earth-centric life-diagnostic

Insulin/IGF-like signalling and brain ageing in Drosophila melanogaster

description: With the steady increase of human lifespan in many countries,
      understanding the underlying mechanisms of aging has become a crucial
      research interest in order to promote human health and longevity and
      prevent age-associated diseases. Over the last few decades, many studies
      have shown that ageing is modulated by the evolutionarily conserved
      nutrient-sensing Insulin/IGF-like signalling (IIS) pathway. IIS interacts
      with multiple cellular processes, including cell growth, development,
      metabolic homeostasis, fecundity and stress resistance. Evidence has
      revealed a strong connection between systemically reduced IIS and
      extension of lifespan, ranging from invertebrate model organisms,
      Drosophila melanogaster, and Caenorhabditis elegans, to mammalians, mice
      and even humans. Systemic mediation of components in the IIS pathway has
      resulted in reduced fecundity, increased lifespan and accumulation of
      carbohydrates and lipids. However, there is still much to be discovered
      regarding the regulation of different IIS components in specific tissues
      or organs and their roles in ageing and longevity. Overexpression of dPTEN
      or dFOXO (the antagonistic regulators of the IIS pathway), systemically or
      tissue-specifically, is reported to extend lifespan or delay specific
      tissue or organ ageing such as muscle and cardiac ageing. However, little
      is known about the role of IIS in neuronal ageing. The effects of altered
      IIS on all neurons in Drosophila was recently tested using the insulin
      receptor dominant-negative model (elavGAL4/UAS-InRDN). This project aims
      to continue investigating the role of reduced IIS in neurons on brain
      functions, ageing, and longevity using inducible overexpression of PTEN to
      reduce IIS in the D. melanogaster model and to determine the role of
      reduced IIS during development and adulthood. The effects are tested
      through lifespan, behavioural senescence (negative geotaxis, exploratory
      walking, and sleeping behaviours), biochemistry and cellular experiments
      including stress resistance, glycogen, and lipid content assays, and
      apoptosis assay. Our results confirm that IIS modulated lifespan and
      healthspan independently and reducing IIS in neurons caused detrimental
      functional effects in flies.

description: Open and collaborative research is becoming increasingly important. While open practices are now required more often, research culture has not yet adapted to accommodate and recognize new ways of working. This can lead to those researchers advocating for and engaging in open and inclusive practices to become run down and maybe even burn out. Open Life Science (OLS), a 16-week online mentorship and cohort-based training, teaches Open Leadership skills that allow participants to grow and sustain communities around their projects. This presentation introduces the importance of self care and wellbeing within the OLS curriculum. It provides exercises to reflect on current care and well-being strategies for individuals and within their community or workplace.

description: We propose a general method for solving exactly the static field equations of Einstein and Einstein-Maxwell gravity minimally coupled to a scalar field. Our method starts from an ansatz for the scalar field profile, and determines, together with the metric functions, the corresponding form of the scalar self-interaction potential. Using this method we prove a new no-hair theorem about the existence of hairy black-hole and black-brane solutions and derive broad classes of static solutions with radial symmetry of the theory, which may play an important role in applications of the AdS/CFT correspondence to condensed matter and strongly coupled QFTs. These solutions include: 1) four- or generic $(d+2)$-dimensional solutions with planar, spherical or hyperbolic horizon topology; 2) solutions with AdS, domain wall and Lifshitz asymptotics; 3) solutions interpolating between an AdS spacetime in the asymptotic region and a domain wall or conformal Lifshitz spacetime in the near-horizon region.

description: The paper presents a numerical technique for computing directly the Takens-Bogdanov points in the nonlinear system of differential equations with one constant delay and two parameters. By representing the delay differential equations as abstract ordinary differential equations in their phase spaces, the quadratic Takens-Bogdanov point is defined and a defining system for it is produced. Based on the descriptions for the eigenspace associated with the double zero eigenvalue, we reduce the defining system to a finite dimensional algebraic equation. The quadratic Takens-Bogdanov point, together with the corresponding values of parameters, is proved to be the regular solution of the reduced defining system and then can be approximated by the standard Newton iteration directly.

Effects of Minimalist Footwear and Stride Length Reduction on Metatarsal Strains and the Probability of Stress Fracture in Running

subject: Musculoskeletal modeling

description: Stress fractures are common running injuries associated with the mechanical fatigue of bone. The metatarsal bones in the foot frequently develop stress fractures due to the repetitive loading they experience while running. Similar to basic engineering materials, the number of loading cycles to bone failure (i.e., stress fracture) increases exponentially with the applied magnitude of loading. Therefore, the objective of this thesis was to examine the relative effects of two potential stress-reducing mechanisms – shoe type and stride length adjustment – on metatarsal strains and the probability of failure in running. Running in a minimalist shoe increased metatarsal strains and the probability of failure, while running with a 10% stride length reduction was not effective at reducing metatarsal strains or the probability of failure. These findings offer an explanation for why metatarsal stress fractures are frequently observed in minimalist shoe users, and suggest that running in traditional footwear lowers metatarsal strains.

description: Higher educational institutions have been using faculty portfolios to help ensure that the mission of academia is being met. This study aimed to develop a faculty portfolio using a sequential mixed methods design. The portfolio development process took place in King Saud bin Abdulaziz University of Health Sciences (KSAU-HS) colleges based in Riyadh, Jeddah and Alhassa, Saudi Arabia. In-depth interviews and focus groups, two ubiquitous approaches for qualitative research, were used to collect data from purposefully selected interviewees (n = 18) and focus group participants (n = 24). The quantitative arm of this study included questionnaire administration to 66 participants. They completed a 59-item questionnaire developed to obtain evidence of the validity and reliability of items used to form a portfolio. The audio taped and videotaped data were transcribed and analysed using thematic content analysis. The quantitative data were analysed using between group differences. This hybrid approach identified five main portfolio domains and their 59 subdomains. The individual domains, which were prioritized using judgemental weightings assigned by 18 participants, included education, service, research, professional development and academic management and leadership. Subdomains were identified within focus groups, with a total of 59 items representing measurable faculty daily activities that constitute the five main domains. The portfolio scores were found to have good reliability and validity based on the quantitative analyses and their triangulation with the qualitative results, thereby providing evidence of the trustworthiness and credibility of the data. This study informs the scientific community by presenting a faculty portfolio developed through a multi-step validation process. It is expected that this faculty portfolio will be implemented successfully in KSAU-HS colleges because its development is based on the opinions of all stakeholders affiliated with this higher educational institution.

Especially those design processes categorized into robotic and multi variant encountered in the automotive body-in-white production stages. Unlike established manual and template-based assembly system design models, which are currently applied in industry, the here presented novel approach uses a knowledge-based search algorithm and automatically generates optimal assembly system configurations. The algorithm has been implemented in a software prototype and the results have been validated against different large-size industrial scenarios in the automotive field of body-in-white production.

description: Electromyography (EMG), the methodology to record muscle activity, has been unchanged for many years, with the use of instrumentation amplifiers (IAs). To overcome limitations of IAs when measuring EMG activity from pennate muscles, a transimpedance amplifier (TIA) has been proposed [1]. The TIA has the advantage of conserving all frequency information in the EMG signal. However, there are some limitations of the originally proposed current-amplifier. In this thesis, we present the design and development of an improved current-amplifier. Additionally, an isolation module was developed to record from multiple muscles simultaneously. The new current-amplifier was used in two experiments. The first experiment was conducted to test coherence, a metric that determines similarity in the frequency content of two signals, as an indicator of fatigue during a dynamic activity. The second experiment was conducted to test the ability of a biofeedback system to modulate coherence.

description: The increase of existing computational capabilities has made simulation emerge as a third discipline of Science, lying midway between experimental and purely theoretical branches [1, 2]. Simulation enables the evaluation of quantities which otherwise would not be accessible, helps to improve experiments and provides new insights on systems which are analysed [3-6]. Knowing the fundamentals of computation can be very useful for scientists, for it can help them to improve the performance of their theoretical models and simulations. This review includes some technical essentials that can be useful to this end, and it is devised as a complement for researchers whose education is focused on scientific issues and not on technological respects. In this document we attempt to discuss the fundamentals of High Performance Computing (HPC) [7] in a way which is easy to understand without much previous background. We sketch the way standard computers and supercomputers work, as well as discuss distributed computing and discuss essential aspects to take into account when running scientific calculations in computers.

description: Neutrinos elastically scattered off atomic electrons offer a unique opportunity to probe the Standard Model (SM) and beyond SM physics. In this work, we examine the new physics effects of light mediators through elastic neutrino-electron scattering using solar neutrinos at the low energy range of PandaX-4T. These mediators, with a mass less than $1$ GeV, are common properties of extensions to the SM. Accordingly, we consider universal light mediator models involving scalar, vector, and tensor interactions allowed by Lorentz invariance, and the anomaly-free $U(1)'$ extensions of the SM with a new vector mediator such as the $L_e-L_μ$, $L_e-L_τ$ and $L_μ-L_τ$ gauge models in which the charges are exclusively leptonic. The new physics effects are analyzed by embedding each model into the SM process using solar neutrino flux. We obtain novel constraints on the coupling-mass plane of these models from the latest Run0 and Run1 datasets of the PandaX-4T experiment. We also compare our results with other limits derived from various terrestrial and astrophysical experiments. Our analysis results reveal more stringent limits in some regions of parameter space.

The design is based on a cubic geometry with four supports placed symmetrically about the optical axis in a tetrahedral configuration. To measure the inertial force sensitivity, a laser is locked to the cavity while it is inverted about three orthogonal axes. The maximum acceleration sensitivity is 2.5\times10^-11/g (where g=9.81 ms^-2), the lowest passive sensitivity to be reported for an optical cavity.

description: We present detailed chemical abundances in 8 clusters in the Large Magellanic Cloud (LMC). We measure abundances of 22 elements for clusters spanning a range in age of 0.05 to 12 Gyr, providing a comprehensive picture of the chemical enrichment and star formation history of the LMC. The abundances were obtained from individual absorption lines using a new method for analysis of high resolution ($R\sim$25,000) integrated light spectra of star clusters. This method was developed and presented in Papers I, II, and III of this series. In this paper, we develop an additional integrated light $χ^2$-minimization spectral synthesis technique to facilitate measurement of weak ($\sim$15 mÅ) spectral lines and abundances in low signal-to-noise ratio data (S/N$\sim$30). Additionally, we supplement the integrated light abundance measurements with detailed abundances that we measure for individual stars in the youngest clusters (Age$+0.5$) and increases with decreasing age, indicating a strong contribution of low-metallicity AGB star ejecta to the interstellar medium throughout the later history of the LMC. We also find a correlation of integrated light Na and Al abundances with cluster mass, in the sense that more massive, older clusters are enriched in the light elements Na and Al with respect to Fe, which implies that these clusters harbor star-to-star abundance variations as is common in the Milky Way.

description: This thesis explored the impact of team conflict and core self-evaluations on student burnout in using engineering student teams in a first-year engineering course. Three patterns of conflict emerged at the mid-semester time-point: a task conflict dominant profile, a relationship conflict/process conflict minor profile, and a midrange conflict profile. Supplemental analyses identified four emergent profiles at the end of the semester. A multilevel model including core self-evaluations as a predictor, team conflict profiles as a moderator, and burnout as an outcome found that core self-evaluations significantly predicted disengagement, though not when a number of covariates were taken into account, and that the interaction between core self- evaluations and team conflict profiles was not significant. The findings and implications for the Job Demands-Resources Model are discussed, as are suggestions for future researchers.

description: The far site detector complex of the Daya Bay reactor experiment is proposed as a location to search for sterile neutrinos with > eV mass. Antineutrinos from a 500 kCi 144Ce-144Pr beta-decay source (DeltaQ=2.996 MeV) would be detected by four identical 20-ton antineutrino targets. The site layout allows flexible source placement; several specific source locations are discussed. In one year, the 3+1 sterile neutrino hypothesis can be tested at essentially the full suggested range of the parameters Delta m^2_{new} and sin^22theta_{new} (90% C.L.). The backgrounds from six nuclear reactors at >1.6 km distance are shown to be manageable. Advantages of performing the experiment at the Daya Bay far site are described.

description: A new equivalence relation, named relation of 'similarity' is defined and applied in the restricted three-body problem. Using this relation, a new class of trajectories (named 'similar' trajectories) are obtained; they have the theoretical role to give us new details in the restricted three-body problem. The 'similar' coordinate systems allow us in addition to obtain a unitary and an elegant demonstration of some analytical relations in the Roche geometry. As an example, some analytical relations published in Astrophysical Journal by Seidov in 2004 are demonstrated.

description: Personalized interaction is highly valued by parents in their story-reading activities with children. While AI-empowered story-reading tools have been increasingly used, their abilities to support personalized interaction with children are still limited. Recent advances in large language models (LLMs) show promise in facilitating personalized interactions, but little is known about how to effectively and appropriately use LLMs to enhance children's personalized story-reading experiences. This work explores this question through a design-based study. Drawing on a formative study, we designed and developed StoryMate, an LLM-empowered personalized interactive story-reading tool for children, following an empirical study with children, parents, and education experts. Our participants valued the personalized features in StoryMate, and also highlighted the need to support personalized content, guiding mechanisms, reading context variations, and interactive interfaces. Based on these findings, we propose a series of design recommendations for better using LLMs to empower children's personalized story reading and interaction.

description: Aquest conjunt d’eines elaborat per AGORAge és el resultat d’un any de camí del projecte de ciència ciutadana AGORAge: Envellir en una comunitat cuidadora. Es tracta d’una selecció d’eines i tècniques recopilades, adaptades o creades per aquelles persones interessades en promoure la creació de comunitats cuidadores on, la inclusió social de la gent gran, sigui rellevant. Pot ser útil tant per equips de recerca i professionals que treballen en l’àmbit de la intervenció social, com per responsables polítics, proveïdors de serveis i ajuntaments. Els objectius principals són, d’una banda, ensenyar tècniques de diagnòstic i intervenció a través de l’experiència concreta del projecte d’AGORAge; i de l’altra, proporcionar més recursos (bones pràctiques, conjunts d’eines i recomanacions) que fomentin la creació de comunitats cuidadores. La utilitat i idoneïtat d’aquestes eines requerirà d’una adaptació a cada projecte específic, al context en que s’utilitzin i a qui les faci servir. Si bé, el més rellevant en tots els casos és conèixer la situació de partida, és a dir, comprendre les necessitats i exigències de les persones implicades. Així, per tal de conèixer aquesta realitat, resulta fonamental posar-se en contacte amb el grup beneficiari des d’un bon inici, i implicar-lo al màxim en les diferents fases de la recerca. Us convidem a consultar aquestes eines i a fer una ullada als conceptes, mètodes, tècniques, exemples i resultats, i així, us hi podreu familiaritzar.
Thermal Simulation and Optimization of SAGD Process: Case Study on Surmont Pilot Project

description: Overlying top water and gas thief zones have a detrimental effect on the Steam-Assisted Gravity Drainage (SAGD) recovery process since steam penetrates into these zones which results in great heat loss. Due to the presence of these top thief zones, recovering bitumen by the SAGD process has become challenging for the Athabasca oil sands. Numerical simulations, laboratory experiments and field production data have demonstrated that oil production tends to decrease as the depletion of top gas occurs; also, heat loss to the overlying thief zone will be more significant when a top water zone is present. Indeed, SAGD is a coupled geomechanical, thermal and fluid flow problem, and continuous steam injection in this process changes reservoir pore pressure and temperature, which can alter the effective stress in-situ. Therefore, to represent the physics of thermal flow and soil geomechanics, a coupled geomechanical simulation that solves the flow and stress equations simultaneously in the reservoir is crucial for modeling the SAGD process. The objective of this study is to construct a 3D geostatistical model for a Surmont pilot and implement coupled geomechanical modeling for the SAGD process aiming at investigating the impact of dilation and thermal expansion on the surface subsidence and bitumen recovery. Reasonable history match of oil and water rates has been achieved and steam chamber profiles have been conformed to the field data from the observation wells. An Expanding Solvent Steam-Assisted Gravity Drainage (ES-SAGD) process has been investigated on a full field-based heterogeneous simulation model using an optimal solvent mixture. Finally, geomechanical effects on the ES-SAGD process are investigated through an iterative coupling approach.
Queer japanese cinema : a rich and diverse cultural history’s challenge to hegemonic ideologies of gender and sexuality

description: There is a rich and diverse corpus of queer Japanese cinema that relates to Japan’s pre-modern cultural specificities around and apropos of male-male sexuality and non-normative genders. A significant amount of academic work has explored and articulated Japan’s queer past; however, Japan’s queer cinema has largely been ignored and/or overlooked. The first chapter provides my anthropological foundation for male-male sexuality in the samurai class and queer gendered embodiments through the bishōnen and onnagata. In the second chapter, I explore the West’s (particularly, America’s) ideological influence on Japan in terms of gender and sexuality. This Western influence managed to obliterate Japan’s queer cultural history. This chapter will investigate the reason behind Japan’s assimilation of Western ideologies in relation to gender and sexuality. In the third chapter, I construct a theoretical model that examines how the cinematic apparatus works to maintain normative ideologies on gender and sexuality. I term this model the Gendered Sexuality Ideological Cinematic Apparatus (GSICA) and employ Foucault, Althusser and Butler as critical philosophers that offer tools in the construction of the GSICA. The GSICA is a key theory because it works to elucidate the meaning behind Japan’s cinematic representation of male-male sexuality and non-normative gender. I examine four generic categories in Japanese cinema: samurai jidaigeki, samurai shin jidaigeki, yakuza gendaigeki and shin yakuza gendaigeki. I argue that these films, in representing specific time periods, work to either repudiate cultural history and/or represent it explicitly in relation to the time period which the film depicts. These representations allude to an intense queer representational and cultural struggle in Japanese cinema. It is time for the recognition of queer Japanese cinemas. These films illustrate the resilient sense of Japanese culture(s) via a (re)connection with ideologies of gender and sexuality that existed prior to Japan’s modernization and assimilation of Western ideological frameworks.
