LEA_D3.2 Requirements for professional teacher training for innovative technologies and needs workshop methodologies
Creators: name: Freudenberg, Rita

Publisher: name: Zenodo
Year: 2019
Subjects: learning technology, innovation procurement, digital learning barriers

description: This report is Deliverable D3.2 connected to task 3.3 in the 3rd work package and is part of MS3 of the LEA project. The leader of the work package is Otto-von-Guericke-University, who also compiled the deliverable. Task 3.3 aims to detect the barriers which prevent the use of learning technology in schools as well as the competencies needed by students and teachers.

The use of digital learning technology has great potential for the school sector. It can promote individual and lifelong learning via the use of special learning environments and prepare content in a form that would be difficult or impossible to implement with conventional means. This is accompanied by new methodological approaches that enable or simplify forms of collaborative work.

Nevertheless, the implementation of learntech in schools is not always possible without issues. There are certain barriers, both on the part of teachers and students, which must be identified and overcome. For this reason, the full potential of learntech for use in schools often cannot be fully exploited. Furthermore, when procuring innovative learning technology, it is important to recognize these barriers for a successful implementation in schools.

The Z axis connected the most anterior point of the sternoclavicular joint and the most posterior point of the ACJ, pointing toward ACJ, the Y axis was perpendicular to the Z axis and pointed to the cranial direction, the X axis was perpendicular to both the Y and Z axes and pointed to the anterior direction, and the origin of the coordinate system was set to the midpoint between the most anterior point of the sternoclavicular joint and the most posterior point of the ACJ on the Z axis.
Annealing behaviour of cold deformed AA3003 aluminum alloys
Creators: name: Babaghorbani, Payman
Publisher: name: University of British Columbia
Year: 2015

description: AA3xxx series aluminum alloys which are used in automotive heat exchangers usually experience a complicated thermomechanical history with a number of processing steps including homogenization, extrusion, cold deformation and then annealing. The cold deformation can involve a wide range of strains, for example, a few percent strain for micro-multiport tubing and large strains for tube drawing. Often the parts are annealed either as a separate processing step or in conjunction with the brazing operation. Results from industry suggest that a wide range of microstructures can be observed after brazing, ranging from coarse multi-crystals to fine grained polycrystalline microstructures. As such, annealing behaviour of cold deformed AA3003 based alloys after extrusion was investigated in this work. Experimental work was conducted on two alloys homogenized prior to extrusion: 3003 (0.54 wt% Fe) and low Fe 3003 (0.09 wt% Fe). A variety of homogenization heat treatments were examined in order to produce the starting materials. Microstructure, yield stress, work hardening and recrystallization behavior of these alloys with different initial microstructures were investigated. A wide range of pre-strain (1-80%) was applied at room temperature using tensile test and rolling. Although most of the annealing treatments were done at 600 °C, samples with pre-strains larger than 0.1 were also annealed at 350-600 °C to study the effect of temperature on microstructure evolution. The minimum strain required to initiate recrystallization was experimentally measured for each condition using tapered samples. As expected, it was found that dispersoids significantly inhibit recrystallization process and can change the critical strain for recrystallization as high as 18%. In addition, contribution from different strengthening mechanisms on the yield stress and work hardening behaviour was calculated and then a model was developed to describe the stress-strain response. The model represents experimental data within ±10% for both yield stress and UTS over a wide range of conditions. Consequently, a physically based model was developed for the critical strain required to initiate recrystallization. This is the first attempt, to the author’s best knowledge, to model critical strain in a system with distribution of fine and relatively large precipitates.

Su'nan chuida in the Jiangnan area of China : a holistic approach
Creators: name: Shao, Rong
Publisher: name: University of British Columbia
Year: 2015

description: This thesis is a study of the ritual music in southern Jiangsu 江蘇 province, the region of Wu-speaking Chinese people 吴人. The music is generally known as Su’nan chuida 蘇南吹打 (‘Su’nan blowing-hitting’ [music]). My approach is that of a Chinese musicologist (Zhongguo yinyuexue 中國音樂學), in that I attempt to document history together with an accounting of sociological issues and analytic perspectives. For my fieldwork, I went to a small town named Shaobo 邵伯, which is near Yangzhou. The xiao paizi 小牌子 (‘little label’) tradition in Shaobo is believed to be one representative type of chuida. During my research, I have attempted a close observation and comprehensive understanding of the history, social values and qualities of Su’nan chuida music. I have also explored evidence of a connection between Su’nan chuida and Kunqu 崑曲 opera based upon analysis of a representative taoqu 套曲 suite form entitled Xia Xifeng 下西風.
Whose cache line is it anyway : automated detection of false sharing
Creators: name: Spear, Mark Anthony
Publisher: name: University of British Columbia
Year: 2015

description: The abstraction of a cache is useful to hide the vast difference in speed of computer processors and main memory. For this abstraction to maintain correctness, concurrent access to memory by different processors has to be coordinated such that a consistent view of memory is maintained. Cache coherency protocols are responsible for this coherency, but can have adverse implications for performance. The operational granularity of these protocols is a “cache line” (e.g. 64 bytes). Depending on the data contained in the cache line and the data’s access patterns, the coherence can be superfluous and the performance implications severe: Consider the case where each byte within a cache line is exclusively read and written by specific cores and no coherence between cores should be necessary. My collaborators and I developed a system which detects this phenomenon, known as false sharing, (my thesis), and present a system that can automatically rewrite programs as they are running to avoid the performance penalty. Some parallel programming benchmarks such as linear regression can see up to 3x-6x performance improvement.
High Rayleigh number convection with double diffusive fingers
Creators: name: Hage, Ellen
name: Tilgner, Andreas
Publisher: name: arXiv
Year: 2010
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: An electrodeposition cell is used to sustain a destabilizing concentration difference of copper ions in aqueous solution between the top and bottom boundaries of the cell. The resulting convecting motion is analogous to Rayleigh-Bénard convection at high Prandtl numbers. In addition, a stabilizing temperature gradient is imposed across the cell. Even for thermal buoyancy two orders of magnitude smaller than chemical buoyancy, the presence of the weak stabilizing gradient has a profound effect on the convection pattern. Double diffusive fingers appear in all cases. The size of these fingers and the flow velocities are independent of the height of the cell, but they depend on the ion concentration difference between top and bottom boundaries as well as on the imposed temperature gradient. The scaling of the mass transport is compatible with previous results on double diffusive convection.
The circuitry of memory : time and space in Mad Men
Creators: name: Lewis, Molly Elizabeth
Publisher: name: University of British Columbia
Year: 2015

description: Memory is central to Mad Men (Matthew Weiner 2007-15) as a period piece set in the 1960s that activates the memories of its viewers while also depicting the subjective memory processes of its protagonist Donald Draper (Jon Hamm). Narratively, as much as Don may try to move forward and forget his past, he ultimately cannot because the memories will always remain. Utilizing the philosophy of Henri Bergson, I reveal that the series effectively renders Bergson’s notion of the coexistence of past and present in sequences that journey into the past without ever leaving the present. Mad Men ushers in a new era of philosophical television that is not just perceived, but also remembered. As a long-form serial narrative that intricately layers past upon present, Mad Men is itself an evolving memory that can be revisited by the viewer who gains new insight upon each viewing. Mad Men is the ideal intersection of Bergson’s philosophy of the mind and memory and Gilles Deleuze’s cinematic philosophy of time. The first chapter simply titled “Time,” examines the series’ first flashback sequence from the episode “Babylon,” in it finding the Deleuzian time-image. The last chapter “Space,” seeks to identify the spatial structure of the series as a whole and how it relates to its slow-burning pace. Chapter two, “Memory,” highlights the viewer’s memory making processes, and appropriately bridges “Time” and “Space” together, just as it bridges spatial and temporal consciousness together for the individual. This thesis emphasizes the individualized experience of the Mad Men viewer who watches Don evolve over seven seasons. Two narrative structural aspects of the series are shown to be especially activating of the viewer’s memory: its flashback sequences and its meditative moments featuring Don in deep contemplation. With reference to literary theory that has identified the concepts of Bergson in the modernist literature movement, as well as to Bergson’s schemas that precisely illustrate his concepts, this thesis concludes that Mad Men can be understood as a carousel that takes viewers on a trip through the circuitry of memory.

description: Geographical random forest (GRF) is a recently developed and spatially explicit machine learning model. With the ability to provide more accurate predictions and local interpretations, GRF has already been used in many studies. The current GRF model, however, has limitations in its determination of the local model weight and bandwidth hyperparameters, potentially insufficient numbers of local training samples, and sometimes high local prediction errors. Also, implemented as an R package, GRF currently does not have a Python version which limits its adoption among machine learning practitioners who prefer Python. This work addresses these limitations by introducing theory-informed hyperparameter determination, local training sample expansion, and spatially-weighted local prediction. We also develop a Python-based GRF model and package, PyGRF, to facilitate the use of the model. We evaluate the performance of PyGRF on an example dataset and further demonstrate its use in two case studies in public health and natural disasters.

description: The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters using all publicly available data in the XMM-Newton Science Archive. Its main aims are to measure cosmological parameters and trace the evolution of X-ray scaling relations. In this paper we present the first data release from the XMM Cluster Survey (XCS-DR1). This consists of 503 optically confirmed, serendipitously detected, X-ray clusters. Of these clusters, 255 are new to the literature and 356 are new X-ray discoveries. We present 464 clusters with a redshift estimate (0.06 < z < 1.46), including 261 clusters with spectroscopic redshifts. In addition, we have measured X-ray temperatures (Tx) for 402 clusters (0.4 < Tx < 14.7 keV). We highlight seven interesting subsamples of XCS-DR1 clusters: (i) 10 clusters at high redshift (z > 1.0, including a new spectroscopically-confirmed cluster at z = 1.01); (ii) 67 clusters with high Tx (> 5 keV); (iii) 131 clusters/groups with low Tx (< 2 keV); (iv) 27 clusters with measured Tx values in the SDSS `Stripe 82' co-add region; (v) 78 clusters with measured Tx values in the Dark Energy Survey region; (vi) 40 clusters detected with sufficient counts to permit mass measurements (under the assumption of hydrostatic equilibrium); (vii) 105 clusters that can be used for applications such as the derivation of cosmological parameters and the measurement of cluster scaling relations. The X-ray analysis methodology used to construct and analyse the XCS-DR1 cluster sample has been presented in a companion paper, Lloyd-Davies et al. (2010).

The first movements of Bruckner's third, sixth and seventh symphonies : a moment-by-moment approach to form
Creators: name: Steinwand, Nicholas Robert
Publisher: name: University of British Columbia
Year: 2015

description: To date, there has been mixed success in explaining Bruckner’s idiosyncratic style, and new methods are needed to explore his compositional techniques. This dissertation proposes an alternative way of studying the music, by examining the small, moment-to-moment gestures and changes in three first movements from his symphonies. The primary focus is on Bruckner’s manipulation of individual motivic, rhythmic, textural, and harmonic elements that create continuous shifts of tensions at the small-scale level, which sustain the expressive impact of the music. Instead of the teleology of traditional sonata form, these individual moments combine to create an overall dynamic flow in a larger, coherent structure described by Ernst Kurth’s theory of symphonic waves. Additionally, the phrase numbers Bruckner inserted in the autograph scores provide evidence of his organizational intentions. Of the works examined, the first movement of the Third Symphony (chapter 2) comes closest to a standard sonata form, but still displays Bruckner’s unique voice. The movement does not follow Hegelian conceptions common to symphonies by composers like Beethoven, but rather unfolds according to its own devices; the rhetoric is instead one of ebb and flow. The Seventh Symphony (chapter 3) moves further away from sonata form, with the tonal shifts in the first movement not creating drama as typically expected. Dynamic development is impelled by motivic processes rather than by the kind of tonal design that typically supports sonata form. Finally, the Sixth Symphony (chapter 4), long thought of by many as Bruckner’s most conventional use of sonata form, is instead one of the least standard, displaying freer unpredictable variational sections. Continual shifts from one motive or topic to another, ambiguous harmonies, and the wave structure all demonstrate that conceiving of the movement’s structure in terms of sonata form is insufficient. Bruckner managed to develop a highly distinctive style that, when properly understood, reveals his innovation and creativity.

Cis-regulatory somatic mutations and gene-expression alteration in B cell lymphomas
Creators: name: Lefebvre, Calvin
Publisher: name: University of British Columbia
Year: 2015

description: Substantial progress has been achieved in characterizing protein coding (PC) regions for cancer genomes, with large contributions coming from The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC). In order to obtain a complete mutational profile of cancer genomes, the whole genome must be analyzed for two reasons: a large proportion of somatic mutations are within the non-coding region and 80% of the human genome is estimated to have some biological functionality. The dramatic cost reduction afforded by next generation sequencing has now made it tractable to sequence entire cancer genomes, allowing mutational profiling of the functional loci in the non-coding regions, such as cis-regulatory elements. Recent cancer genomic studies observed somatic mutations within cis-regulatory elements have the capacity to deregulate gene expression, but their impact remains underexplored. Initial attempts to prioritize cis-regulatory mutations did not incorporate RNASeq. We used 84 B cell lymphoma samples to address this limitation by prioritizing disruptive cis-regulatory mutations based on their potential to be the cause of observable cascading expression changes throughout biological networks. BCL6, ROBO1, GNA13, HAS2 and MYC were dysregulated genes targeted with somatic mutations through different mechanisms. Mutations either targeted the genes directly (PC mutations), indirectly (cis-regulatory mutations) or both. Our analyses demonstrates the importance of identifying genomically altered cis-regulatory elements, along with gene expression data, to interpret the mutational landscapes of cancers.

description: The hydrodynamic lift force that polymers experience near boundaries is known to be a crucial element when considering rheological flows of dilute polymer solutions. Here we develop theory to describe the hydrodynamic lift force on extended polymers flowing near flat surfaces. The lift force is shown to display a non-monotonic character increasing linearly with the distance to the wall $Z$ in the near-surface regime defined as $ZL$ we recover the well known far-field result in which the force decays as $Z^{-2}$. Our analytical theory has important implications in understanding adsorption, desorption, and depletion layers of highly extended objects in flow.

description: Electrometry near a dielectric surface is performed using Rydberg electromagnetically induced transparency (EIT). The large polarizability of high n-state Rydberg atoms gives this method extreme sensitivity. We show that adsorbates on the dielectric surface produce a significant electric field that responds to an applied field with a time constant of order one second. For transient applied fields (with a time scale of < 1 s) we observe good agreement with calculations based on numerical solutions of Laplace's equation using an effective dielectric constant to simulate the bulk dielectric.

Performance-based seismic design and assessment of concrete bridge piers reinforced with shape memory alloy rebar
Creators: name: Billah, Abu Hena MD Muntasir
Publisher: name: University of British Columbia
Year: 2015

description: Recent advancements in numerical analysis and computational power have pushed the current bridge design specifications towards a more descriptive performance-based seismic design (PBSD) approach as compared to the conventional force-based method. One major attributes of this PBSD is to keep bridges operational and reduce the repair cost by limiting the global and local deformations of a bridge to acceptable levels under design loads. Shape memory alloy (SMA), with its distinct superelasticity, shape memory effect and hysteretic damping, is a promising material for the application in bridge piers to attain the objectives of PBSD. The objective of this research is to develop a performance-based seismic design guideline for concrete bridge pier reinforced with different types of SMAs. With the aim of providing a comprehensive design guideline, this study started with the experimental investigation of bond behavior of smooth and sand coated SMA rebar in concrete using pushout specimens. The test results were explored to evaluate the influence of concrete strength, bar diameter, embedment length, and surface condition. In addition, a plastic hinge length expression for SMA-RC bridge pier was developed which can be used for calculating the flexural displacement capacity and design of SMA-RC bridge pier. Using Incremental Dynamic Analysis (IDA), this study developed quantitative damage states corresponding to different performance levels (cracking, yielding, and strength degradation) and specific probabilistic distributions for RC bridge piers reinforced with different types of SMAs. Based on an extensive numerical study, the author proposed residual drift based damage states for SMA-RC pier. Based on the proposed damage states, a sequential procedure for the performance-based design of SMA-RC bridge pier is developed using a combination of residual and maximum drift. Finally, in order to elucidate the potential benefit and applicability of the proposed guideline, fragility curves and seismic hazard curves for different SMA-RC bridge piers are developed considering maximum and residual drift as engineering demand parameters. It is found that the SMA-RC bridge piers designed following the proposed design guideline have very low probability of damage resulting in a lower annual loss which will provide significant financial benefit in the long run.

description: [abridged] The inspiral of a stellar compact object into a massive black hole is one of the main sources of gravitational waves for the future space-based Laser Interferometer Space Antenna. We expect to be able to detect and analyze many cycles of these slowly inspiraling systems. To that end, the use of very precise theoretical waveform templates in the data analysis is required. To build them we need to have a deep understanding of the gravitational backreaction mechanism responsible for the inspiral. The self-force approach describes the inspiral as the action of a local force that can be obtained from the regularization of the perturbations created by the stellar compact object on the massive black hole geometry. In this paper we extend a new time-domain technique for the computation of the self-force from the circular case to the case of eccentric orbits around a non-rotating black hole. The main idea behind our scheme is to use a multidomain framework in which the small compact object, described as a particle, is located at the interface between two subdomains. Then, the equations at each subdomain are homogeneous wave-type equations, without distributional sources. In this particle-without-particle formulation, the solution of the equations is smooth enough to provide good convergence properties for the numerical computations. This formulation is implemented by using a pseudospectral collocation method for the spatial discretization, combined with a Runge Kutta algorithm for the time evolution. We present results from several simulations of eccentric orbits in the case of a scalar charged particle around a Schwarzschild black hole. In particular, we show the convergence of the method and its ability to resolve the field and its derivatives across the particle location. Finally, we provide numerical values of the self-force for different orbital parameters.

Although it has been approved for clinical usage for over two decades and a number of studies have worked on the mechanism, many details of the mode of action of daptomycin still remain to be understood. This thesis focuses on shedding light on: i) how daptomycin binds to membranes and whether it forms well-defined oligomers; and ii) whether once in the membrane, daptomycin causes leakage. We have used photon correlation spectroscopy (PSC) to determine the condition under which fusion among vesicles occurs in the presence of daptomycin. 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine/1-palmitoyl-2-oleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (POPC/POPG) liposome is a better system as higher concentrations of Ca²⁺ is required to trigger membrane fusion. Based on these findings of membrane fusion caused by daptomycin, binding and kinetics experiments were conducted to study the interaction between daptomycin and the lipid membrane. The binding between daptomycin or NBD-labeled daptomycin and POPC/POPG or 1,2-dimyristoyl-d54-sn-glycero-3-phosphocholine/1,2-dimyristoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (DMPC/DMPG) liposomes is strong, with micromolar dissociation constants. Förster resonance energy transfer (FRET) experiments were conducted under conditions where fusion is not present. The results show that the oligomerization number n is concentration-dependent. A two-stage equilibrium process is proposed when the daptomycin binds and oligomerizes in the membrane, in which daptomycin accumulates firstly in the membrane to form larger oligomers, facilitating further effects which lead to the cell death, such as the lipid extracting effect on the membrane. In addition, fluorescence experiments were conducted to investigate whether daptomycin causes leakage in POPC/PG and DMPC/PG liposomes, with or without the proton ionophore carbonyl cyanide m-chlorophenyl hydrazine (CCCP). Experiments using the ion-selective pore-forming aurein peptide were also done, as a control. For stable liposomes, daptomycin does not cause ion permeabilization of the membrane, suggesting that the membrane depolarization resulting from daptomycin is different from pore-formation by the aurein peptide. The work described in this thesis provides evidence leading to a clearer mechanism of action for daptomycin.

Coordination chemistry of antimicrobial and anticancer agents

description: The World Health Organization has named the resistance of microbes to known antimicrobial drugs as an increasingly serious threat to global public health. Isolates of the ESKAPE pathogens (E. faecium, S. aureus, K. pneumonia, A. baumanii, P. aeruginosa, and Enterobacter species) are responsible for many nosocomial infections each year that require complicated, and therefore expensive, medical treatment, often leading to death in immune-compromised patients. Over the past 50 years, (fluoro-)quinolone antimicrobial agents have been widely used in the clinic as broad-spectrum antibiotics, but lately growing resistance against this drug class has been reported. Combining metal ions with known organic small-molecule drugs is one strategy to overcome such developed resistances. Previously, the antimicrobial properties of copper(II) and gallium(III) had been investigated, leading to Greek mythology comparisons for their mechanism of action: Cu²⁺ as the ”Achilles Heel”, Ga³⁺ as the ”Trojan Horse” subterfuge for Fe³⁺. In this thesis, gallium(III) and copper(II) coordination complexes of (fluoro-)quinolone antimicrobial agents, and derivatives thereof, were synthesized in an attempt to combine the antimicrobial potency of Cu²⁺ and Ga³⁺ with that of the quinolone antimicrobial agents in one molecule. The antimicrobial susceptibility of these coordination complexes was evaluated against five isolates of the ESKAPE pathogens; combinational effects between the metals and the quinolone ligands were not observed. While the combination of metal ions with small, organic drug molecules may lead to novel potent metallodrugs, the interaction of metal ions with drugs in vivo is often associated with toxic side-effects of medical treatment, for which the iron(III)-mediated cumulative-dose cardiotoxicity of doxorubicin is one example. Vosaroxin is a first-in-class anticancer quinolone derivative in clinical trials. Unlike the anthracycline anticancer drug doxorubicin, vosaroxin is minimally metabolized in vivo. Spectrophotometric titrations and further studies of the isolated tris(vosaroxino)iron(III) and -gallium(III) complexes supported a strong coordination of the metal ion suggesting that vosaroxin treatment may not result in cardiotoxicity.

description: Spin-orbit (SO) coupling -- the interaction between a quantum particle's spin and its momentum -- is ubiquitous in nature, from atoms to solids. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators, which are of extensive interest; it contributes to the electronic properties of materials such as GaAs, and is important for spintronic devices. Ultracold atoms, quantum many-body systems under precise experimental control, would seem to be an ideal platform to study these fascinating SO coupled systems. While an atom's intrinsic SO coupling affects its electronic structure, it does not lead to coupling between the spin and the center-of-mass motion of the atom. Here, we engineer SO coupling (with equal Rashba and Dresselhaus strengths) in a neutral atomic Bose-Einstein condensate by dressing two atomic spin states with a pair of lasers. Not only is this the first SO coupling realized in ultracold atomic gases, it is also the first ever for bosons. Furthermore, in the presence of the laser coupling, the interactions between the two dressed atomic spin states are modified, driving a quantum phase transition from a spatially spin-mixed state (lasers off) to a phase separated state (above a critical laser intensity). The location of this transition is in quantitative agreement with our theory. This SO coupling -- equally applicable for bosons and fermions -- sets the stage to realize topological insulators in fermionic neutral atom systems.

description: The magnetic field of the classical T Tauri star BP Tau can be approximated as a superposition of dipole and octupole moments with respective strengths of the polar magnetic fields of 1.2 kG and 1.6 kG (Donati et al. 2008). We adopt the measured properties of BP Tau and model the disc accretion onto the star. We observed in simulations that the disc is disrupted by the dipole component and matter flows towards the star in two funnel streams which form two accretion spots below the dipole magnetic poles. The octupolar component becomes dynamically important very close to the star and it redirects the matter flow to higher latitudes. The spots are meridionally elongated and are located at higher latitudes, compared with the pure dipole case, where crescent-shaped, latitudinally elongated spots form at lower latitudes. The position and shape of the spots are in good agreement with observations. The disk-magnetosphere interaction leads to the inflation of the field lines and to the formation of magnetic towers above and below the disk. The magnetic field of BP Tau is close to the potential only near the star, inside the magnetospheric surface, where magnetic stress dominates over the matter stress. A series of simulation runs were performed for different accretion rates. They show that an accretion rate is lower than obtained in many observations, unless the disc is truncated close to the star. The torque acting on the star is about an order of magnitude lower than that which is required for the rotational equilibrium. We suggest that a star could lose most of its angular momentum at earlier stages of its evolution.

description: Given an ergodic measure with positive entropy and only positive Lyapunov exponents, its dynamical quantifiers can be approximated by means of quantifiers of some family of uniformly expanding repellers. Here non-uniformly expanding maps are studied that are $C^{1+β}$ smooth outside a set of possibly critical or singular points.
Embracing alterity : rethinking female otherness in contemporary cinema
Creators: name: Davis, Claire
Publisher: name: University of British Columbia
Year: 2015

description: The Other operates as a figure of inherent transgression: A manifestation of the repressions necessary for the sustenance of dominant ideology. As the Other lurches in from the sidelines to threaten and frighten before being neutralized through assimilation or death, dominant ideology is upheld and confirmed by being set against the abnormality and monstrosity of difference. In feminist film theory, otherness has been foundational as a means of describing women’s marginalization within patriarchal society. Where Man is constructed as subject, Woman is constructed as Other. As such, the female Other tells us far more about patriarchal constructions of Woman than it does about female subjects in the world. Feminist film theory demonstrates a pronounced investment in the need for spectatorial identification with female characters, conflating the roles occupied by character and person, and thus the female Other has traditionally been theorized as staunchly misogynistic—the embodiment of patriarchal and phallic fears of female monstrosity and lack. Against this tradition, I propose that the female Other is not always and necessarily an anti-feminist figure. Iterations of the Other that foreground character opacity and thus disrupt empathetic and identificatory methods of spectatorship productively disturb processes of ideological comfort. By refusing to subject the Other to an epistemological narrative structure, one which poses the female Other as mystery to be demystified, and by denying a resolution that destroys the Other and thus the threat that they represent, the films analyzed in this thesis demand an alternative methodology to account for the radical alterity of the female Other. The two case studies offered in support of this thesis are the melancholic Other, with the example of Justine in Melancholia (von Trier 2011) and the posthuman Other, as exemplified in Under the Skin (Glazer 2013) and Ex Machina (Garland 2015). Rather than occupying the traditional role of the female Other as monster, these characters threaten the integrity of the human precisely because of their revelation of the human monstrosity that lies at the heart of patriarchal masculinity.

description: Using the archives of the American Association of Variable Stars Observers and our own data, we analyse the long-term variability of several well-studied Luminous Blue Variables (LBVs) aiming on a general picture of stochastic variability of these objects. The power density spectra of all the selected objects may be generally described by a single power law contaminated by observational noise at higher frequencies. The slopes of the power-law component are close to p=2 (where PDS ~ f^{-p}, and f is frequency) for strongly variable flaring objects like AG Car and significantly smaller (p~1.3) for P Cyg where brightness variation amplitude is
