description: In this article we give the optimal lower bound for the complexity function of a planar translation which induces an ergodic rotation of the torus $\mathbb{R}^2 / \mathbb{Z}^2$. In addition, we give an explicit calculation of this complexity for the application $(x,y) \mapsto (x+1/ϕ^2,y+x-1/ (2ϕ^3))$, where $ϕ$ is the golden mean. Nous proposons dans ce travail de minorer de manière optimale la fonction complexité associée à une translation du plan, qui induit une rotation ergodique du tore $\mathbb R^2/\mathbb Z^2$. De plus, nous donnons un calcul explicite de cette complexité pour l'application $(x,y)\mapsto(x+1/ϕ^2,y+x-1/(2ϕ^3))$, où $ϕ$ désigne le nombre d'or.

description: We investigate generation processes of magnetic fields around first stars. Since the first stars are expected to form anisotropic ionization fronts in the surrounding clumpy media, magnetic fields are generated by effects of radiation force as well as the Biermann battery effect. We have calculated the amplitude of magnetic field generated by the effects of radiation force around the first stars in the preceding paper, in which the Biermann battery effects are not taken into account.In this paper, we calculate the generation of magnetic fields by the Biermann battery effect as well as the effects of radiation force, utilizing the radiation hydrodynamics simulations. As a result, we find that the generated magnetic field strengths are ~ 10^{-19}G-10^{-17}G at ~ 100pc-1kpc scale mainly by the Biermann battery, which is an order of magnitude larger than the results of our previous study. We also find that this result is insensitive to various physical parameters including the mass of the source star, distance between the source and the dense clump, unless we take unlikely values of these parameters.

description: This project aims to develop scientific as well as technical foundations towards realization of a novel platform for light-matter interaction based on tapered optical nanofibers that enable to interface neutral atoms in their vicinity. A setup for magneto-optical trap (MOT) has been built. Tapered nanofibers (TNFs) of sub-wavelength diameter, with transmission of 95 percent have been fabricated and characterized. Next, a nanofiber is transferred into the MOT setup and installed inside the vacuum chamber. The MOT cloud and nanofiber are made to spatially overlap inside ultra-high vacuum (UHV). Coupling of fluorescence of MOT into the guided mode of TNF has been observed. This clearly shows the coupling of atoms with the fiber-guided mode and that our interface works. In addition, 65-70 percent absorption of a free space beam by the atomic cloud has been observed and the relevant MOT parameters are obtained from it. Our efforts are directed towards observing interaction of atoms with the fiber-guided light via evanescent field. Attempts have been made to observe absorption of a probe beam through the nanofiber by the MOT cloud and techniques for switching on-off the MOT beams, the probe beam and the magnetic field are developed for that purpose. Ultimately, the goal will be to trap atoms in the vicinity of a nanofiber enabling to reach a large optical depth accompanied by the ability to reach high intensities for low optical power. I will present my work on the development of this MOT-nanofiber interface - a new promising platform for research in nonlinear quantum optics, quantum information science and technology, quantum communication and hybrid quantum system.
An updated catalog of M33 clusters and candidates: $UBVRI$ photometry, and some statistical results

description: We present $UBVRI$ photometry for 392 star clusters and candidates in the field of M33, which are selected from the most recent star cluster catalog. In this catalog, the authors listed star clusters' parameters such as cluster positions, magnitudes and colors in the $UBVRIJHK_s$ filters, and so on. However, a large fraction of objects in this catalog do not have previously published photometry. Photometry is performed using archival images from the Local Group Galaxies Survey, which covers 0.8 deg$^2$ along the major axis of M33. Detailed comparisons show that, in general, our photometry is consistent with previous measurements. Positions (right ascension and declination) for some clusters are corrected here. Combined with previous literature, we constitute a large sample of M33 star clusters. Based on this cluster sample, we present some statistical results: none of the M33 youngest clusters ($\sim 10^7$ yr) have masses approaching $10^5$ $M_{\odot}$; roughly half the star clusters are consistent with the $10^4$ to $10^5$ $M_{\odot}$ mass models; the continuous distribution of star clusters along the model line indicates that M33 star clusters have been formed continuously from the epoch of the first star cluster formation until recent times; there are $\sim 50$ star clusters which being overlapped with the Galactic globular clusters on the color-color diagram, and these clusters are old globular clusters candidates in M33.

subject: English as an Additional Language

description: In recent years, the demographic profile of Canada has undergone rapid changes as increasing numbers of immigrants have chosen to call this country home. The Canadian K-12 and post-secondary educational systems have seen an enormous influx of language minority (LM) learners: 25% of the student body in Calgary’s K-12 systems have or have had EAL coding, and the proportion of local LM students in tertiary settings is even higher. Previous research has demonstrated that despite graduating in high numbers, many of these students struggle with academic language proficiency and experience difficulties in post-secondary settings, as exhibited in low GPAs and high rates of failed courses. In response to the academic needs of the ‘new mainstream’ of university entrants, the iEAP (intensive English for Academic Purposes) curriculum was designed, developed, and implemented as an intervention between high school and university. This thesis describes the iEAP curriculum and presents short-term outcomes based on pre- and post-testing and long-term outcomes based on subsequent academic performance. The short-term quantitative findings demonstrate that the iEAP participants displayed high rates of improvement on a variety of academic language measures. The long-term findings on academic performance were more difficult to measure due to confounding variables, and indicate that there was a wide range of academic outcomes in the years following participation in iEAP. Qualitative findings are also used to explain, corroborate, and better understand the quantitative findings and present the participants’ experiences in iEAP and university. The conclusion of this study is that growth in academic language proficiency can occur in a short period of time when well-designed and relevant curricula are put into practice.

description: A search for the Standard Model Higgs boson decaying into a pair of tau leptons is reported. The analysis is based on a data sample of proton-proton collisions collected by the ATLAS experiment at the LHC and corresponding to an integrated luminosity of 4.7 fb^-1. No significant excess over the expected background is observed in the Higgs boson mass range of 100-150 GeV. The observed (expected) upper limits on the cross section times the branching ratio for H to tau+ tau- are found to be between 2.9 (3.4) and 11.7 (8.2) times the Standard Model prediction for this mass range.

description: Immunoglobulin A (IgA) nephropathy is the most common type of glomerulonephritis worldwide characterized by excessive serum levels of glycosylated which triggers the generation of glycan-specific IgG and IgA autoantibodies. This pathological condition results in the formation of circulatory IgA immune complexes, which are essential for the development of glomerular inflammation, especially IgA nephropathy. The serum galactosylated IgA1, IgG, and IgA autoantibodies are suggested as the biomarkers of IgA nephropathy since IgA antibodies are early markers for disease activity too. Serum IgA antibodies emerged as the early COVID-19-specific antibody response about two days after initial symptoms of COVID-19 in comparison with IgG and IgM antibody concentrations, which appeared after five days. IgA nephropathy is frequently presented as microscopic or macroscopic hematuria and proteinuria with a male predominance. COVID-19 infection can include several organs aside from the lungs, such as kidneys through different mechanisms. It is demonstrated in most cases that short-lasting symptoms such as gross hematuria resolve either spontaneously or following a short course of steroids. This review summarized the reported cases of relapses or denovo reported cases of relapses or de-novo IgA nephropathy and IgA vasculitis following COVID-19 vaccination.
The Roles of Information and Communication Technologies (ICTs) in Indigenous Political Participation and Representation: A Case Study of the 2008-2009 Peruvian Amazon Conflict

description: This thesis examines the emerging and influential roles of Information and Communication Technologies (ICTs) – especially the Internet – in indigenous political participation and representation across the Peruvian Amazon, and uses the 2008-2009 Peruvian Amazon conflict as a case study for analysis. The study employs a mixed methods methodological design for data collection, processing, and analysis, and involves two analytical stages: 1) the examination of quantitative and qualitative data with respect to ICTs and its impacts on indigenous political participation and representation in the Peruvian Amazon and 2) the analysis of quantitative/qualitative data sets combined with a chronological content analysis of the 2008-2009 Peruvian Amazon conflict. Despite the gradual growth of the Internet in the Peruvian Amazon, the findings of this study argue that indigenous Amazonians are using the Internet (specifically the social media platform, Facebook) to create networks with local and global actors, which challenge the controversial neoliberal reforms introduced by Alan García named “The Law of the Jungle” and counter misrepresentations regarding indigenous groups in national/international media. However, the study also finds that ICT access, demographics, socio-political status, indigenous political organization, indigenous leadership, and news media reports hinders a unified indigenous political participation and representation across ICTs during and after the 2008-2009 Peruvian Amazon conflict.
Anomalous Photon-Assisted Tunneling in Graphene

description: We investigated the Dirac electrons transmission through a potential barrier in the presence of circularly polarized light. An anomalous photon-assisted enhanced transmission is predicted and explained in a comparison with the well-known Klein paradox. It is demonstrated that the perfect transmission for nearly-head-on collision in an infinite graphene is suppressed in gapped dressed states of electrons, which is further accompanied by shift of peaks as a function of the incident angle away from the head-on collision. In addition, the perfect transmission in the absence of potential barrier is partially suppressed by a photon-induced gap in illuminated graphene. After the effect of rough edges of the potential barrier or impurity scattering is included, the perfect transmission with no potential barrier becomes completely suppressed and the energy range for the photon-assisted perfect transmission is reduced at the same time.

description: We experimentally investigate the mixing/demixing dynamics of Bose-Einstein condensates in the presence of a linear coupling between two internal states. The observed amplitude reduction of the Rabi oscillations can be understood as a result of demixing dynamics of dressed states as experimentally confirmed by reconstructing the spatial profile of dressed state amplitudes. The observations are in quantitative agreement with numerical integration of coupled Gross-Pitaevskii equations without free parameters, which also reveals the criticality of the dynamics on the symmetry of the system. Our observations demonstrate new possibilities for changing effective atomic interactions and studying critical phenomena.

description: Polycrystalline diamond compact (PDC) drill bit design influences the bit hydraulics and hence the drilling performance. To improve the hydraulics, the fluid flow pattern across the drill bit should be optimized for low pressure drop, low recirculation flow and high velocity. Design of Experiments (DOE) was used to study the effect of various design parameters. Computational Fluid Dynamics (CFD) was used to simulate the fluid flow in the complex geometry of the drill bit. Response Surface Methodology was applied to optimize the design parameters for improved bit hydraulics. Preliminary simulations were conducted by increasing the complexity to meet the real time operation. Simulations based on fractional factorial experiment were used to identify the significant factors from the 15 design parameters. The optimum limits of the most significant five factors were identified from simulations based on central composite design (CCD). The optimization procedure was assessed by comparing the optimum design with the original design for Newtonian and Non-Newtonian conditions.
Essays on the rank-wealth hypothesis
Creators: name: Newton, David
Publisher: name: University of British Columbia
Year: 2010

description: This thesis comprises two manuscripts which sequentially develop and test the Rank-Wealth Model (RWM). The first manuscript constructs the RWM from basic economic principles by assuming consumer good indivisibility. If consumer goods are indivisible, and one also assumes finite supply and homogeneous preferences, the resultant derived utility function of each individual will become their rank in society. This is an important result for it can explain 'Keeping up with the Joneses' motives as well as generate a value function that in the aggregate closely resembles Kahneman and Tversky's Prospect Theory (1979). The RWM can therefore explain a number of nancial anomalies including the endowment effect, simultaneous gambling and insuring, lottery regressivity and sub-optimal diversification. The second manuscript tests some of the predictions that arise from RWM. Using methodology similar to Kumar (2009) the second study begins by confirming the previously documented observation that poor individuals hold more lottery-type-stocks (LTS) than the rich. Next, tests of the RWM are conducted using a proxy variable that measures individual rank as well as the Gini measure of wealth concentration. As expected, high LTS portfolios do underperform low LTS portfolios using standard risk metrics but that dominance is reversed when rank is considered. The second manuscript provides empirical support for the RWM by showing that it may be fully rational for the poorest individuals to concentrate their portfolio value into a few stocks that have higher idiosyncratic risk and skewness even if the (conventional) risk-adjusted expected return of those stocks is negative.
Ab initio prediction of pressure-induced structural phase transition of superconducting FeSe

description: External pressure driven phase transitions of FeSe are predicted using \textit{ab initio} calculations. The calculations reveal that $α$-FeSe takes transitions to NiAs-type, MnP-type, and CsCl-type FeSe. Transitions from NiAs-type to MnP-type and CsCl-type FeSe is also predicted. MnP-type FeSe is also found to be able to transform to CsCl-type FeSe, which is easier from $α$-FeSe than the transition to MnP-type FeSe, but comparable to the transition from NiAs-type FeSe. The calculated electronic structures show that all phases of FeSe are metallic, but the ionic interaction between Fe-Se bonds becomes stronger and the covalent interaction becomes weaker when the structural phase transition occurs from $α$-FeSe to the other phases of FeSe. The experimentally observed decrease in $T_{c}$ of superconducting $α$-FeSe at high pressure may be due to a structural/magnetic instability, which exists at high pressure. The results suggest us to increase the $T_{c}$ of $α$-FeSe if such phase transitions are frustrated by suitable methods.

description: Анализируются принципы игровой мифологии американских фильмов ужасов на примере фильма «Игра» (1997 г.). Визуальная хоррор-деконструкция пределов «серьезного» и «несерьезного» делает игру ведущим социокультурным полигоном, на котором отрабатываются и накапливаются поколенческие модели отношений человека с самим собой и окружающим миром. Подобная голливудская рефлексия становится особенно актуальной и в связи с необходимостью определения повсеместно уничтожаемых властью границ между «официальным» и повседневным, которые для современного социума выступают принципиальными демаркационными вехами. Ужасный и фантасмагоричный сюжет «Игры» демонстрирует условность диктатуры социальных и институциональных пространств и выдвигает идею о том, что только вне подобной системы отношений возможна реализация архетипической судьбы человека. Осознавая призрачность и надуманность принципов социальной и профессиональной коммуникации, зритель получает визуальный образец созидания личностной мифологии, свободной от идеологизированных корпоративных и политических штампов.
The Biaxial Smectic-A* Phase -- A New Phase, Already But Unknowingly Discovered?

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The biaxial smectic-A* (Sm-A_B*) phase, appearing in the phase sequence Sm-A*--Sm-A*_B--Sm-C*, is analyzed using Landau theory. It is found to possess a helical superstructure with a pitch that is significantly shorter than the pitch of the Sm-C* helical superstructure. The Sm-A_B*--Sm-C* transition can be either 1st or 2nd order, and correspondingly there will be either a jump or continuous variation in the pitch. The behaviors of the birefringence and electroclinic effect are analyzed and found to be similar to those of a Sm-C*_alpha phase. As such, it is possible that the Sm-A_B* phase could be misidentified as a Sm-C*alpha phase. Ways to distinguish the two phases are discussed.

We use standard transfer matrix calculations and perform finite-size scaling of the largest inverse Lyapunov exponent to obtain the localization length for respective 3D tight-binding systems. The density of states is obtained from the full spectrum of eigenenergies of the Anderson Hamiltonian. We discuss the phase diagram of the metal-insulator transition and the influence of the correlated disorder on the critical exponents.

description: The Late Jurassic – Early Cretaceous Monteith Formation (Minnes Group) records incipient foredeep deposition in the Alberta Deep Basin. The uppermost lithostratigraphic unit, informally referred to as the Monteith A, is investigated with 550 wells and ~540 m of strata from 29 cores across a 17,500 km2 area. These data provide the basis for characterization of fine- grained, organic rich overbank deposits and sandstonedominated channel belts associated with the fluvial stratum. Sediment was delivered from an orogenic catchment (>100, 000 km2) to a fluvial fan that transported sediment northeast to an axial river system, and is interpreted as a distributive fluvial system (DFS). The associated stratigraphic architecture of the DFS fines upward and is characterized by amalgamated channel belts nearest the point source. The interplay between channel belt amalgamation, channel belt architecture, natural fractures, and burial depth control the reservoir quality and distribution in the study area.

description: Turbulent flow topology around a rectangular cylinder with h/d=8 is characterized by either dipole or quadrupole mean wake depending on the turbulent boundary layer thickness. This study investigates the physical and mathematical mechanisms giving rise to the two distinct types of flow by considering the phase-averaged velocity field. It was found that the vortex stretching and tilting and the time-averaged representation of tilted vortex shedding are the key terms distinguishing between the dipole and quadrupole wake structures. The other objective is to develop a procedure to estimate the higher-rank low order flow based on Extended Proper Orthogonal Decomposition. Within this technique, the global velocity flow can be reconstructed with correlated surface pressure sensors to have a closer look at the mechanisms leading to dipole and quadrupole wakes. It was observed that optimum choice of sensor locations needs analytical considerations to improve the ability of pressure probes in capturing the coherent structures of interest.

Given the high market demand for such micro and nano featured components, different manufacturing methods have been developed for their fabrication. The common technologies in micro/nano fabrication are photolithography, electron beam lithography and other semiconductor processing techniques. Although these methods are capable of fabricating micro/nano structures with a resolution of less than a few nanometers, the shortcomings associated with these methods are, production costs for customized products, limited material choices, necessitate the development of other fabricating techniques. An atomic force microscope (AFM) probe based nano fabrication, has, therefore, been used to overcome some the major restrictions of the traditional processes. This technique removes material from the workpiece by engaging micro/nano size cutting tool (i.e. AFM probe) and is applicable on a wider range of materials compared to the photolithographic process. In spite of the unique benefits of nano mechanical machining, there are also some challenges with this technique, such as size effects, burr formations, chip adhesions, fragility of tools and tool wear. Moreover, AFM based machining does not have any rotational movement, which makes fabrication of 3D features more difficult. Thus, vibration-assisted machining is iii introduced into AFM probe based nano mechanical machining to overcome the limitations associated with the conventional AFM scribing. In this study, scratching tests are performed with a single crystal diamond AFM probe to investigate the cutting characteristics and model the ploughing cutting forces. Calibration of the probe for lateral force measurements is extended through the force balance method. Furthermore, vibration-assisted machining system is developed and applied to fabricate different materials to overcome material selection issue. The novelty of this study includes the application of vibration-assisted AFM probe based nano scale machining to fabricate micro/nano scale features, calibration of an AFM by considering different factors, and the investigation of the nano scale material removal process from a different perspective.

description: INTRODUCTION: The majority of individuals with chronic spinal cord injury (SCI) experience spasticity, which can often impair function and degrade quality of life. Reports by individuals with SCI suggest that whole body vibration (WBV), as can occur while riding wheelchairs, may trigger spasticity. OBJECTIVES: 1) Examine the influence of wheel design on wheelchair vibration. 2) Develop a system allowing exposure of individuals with SCI to WBV and analysis of muscle activity to identify spasticity. METHODS: 1) A wheelchair wheel comparison study: Vibration acceleration and frequency content produced by wheelchairs equipped with 2 different wheel designs (steel spoked and composite material spoked) were compared as: 1a) 13 subjects with SCI wheeled through an obstacle course simulating a wheelchair user's daily activities 1b) 22 non-SCI subjects wheeled down a ramp and over a vibration inducing obstacle. Vibration acceleration was recorded using 2 accelerometers mounted on the wheelchairs' main axle and footrest. The influence of wheelchair vibration on spasticity was assessed using questionnaires, completed by the SCI subjects. 2) A controlled whole body vibration (CWBV) pilot study: 2 SCI subjects were exposed to 7-12 WBV sessions. Each exposure consisted of a single frequency, lasted 20 seconds, and was repeated on 2 separate days. The WBV was applied using an electrodynamic shaker and the subjects' leg muscles' activity was recorded using an electromyography (EMG) system. Muscle spasms were identified by calculating the ratio between periods of increased muscle activity and the period before exposure to vibration. RESULTS: No statistically significant differences (p=0.05) were found in wheelchair vibration acceleration or frequency content between the 2 tested wheel designs and no clear correlation between wheelchair vibration and spasticity was apparent. The CWBV system was able to apply vibration (-+0.5 Hz, -+0.001 g) and record muscle activity (-+7 mV). The CWBV exposures produced several muscle responses that were considered to be spasms. CONCLUSIONS: The tested composite material spoked wheels do not differ, in vibration performance, from steel spoked wheels. The developed CWBV apparatus appears suitable for studying muscle activity in response to WBV.

description: While the presence of discs around classical Be stars is well established, their origin is still uncertain. To understand what processes result in the creation of these discs and how angular momentum is transported within them, their physical properties must be constrained. This requires comparing high spatial and spectral resolution data with detailed radiative transfer modelling. We present a high spectral resolution, R~80,000, sub milli-arcsecond precision, spectroastrometric study of the circumstellar disc around the Be star beta CMi. The data are confronted with three-dimensional, NLTE radiative transfer calculations to directly constrain the properties of the disc. Furthermore, we compare the data to disc models featuring two velocity laws; Keperian, the prediction of the viscous disc model, and angular momentum conserving rotation. It is shown that the observations of beta CMi can only be reproduced using Keplerian rotation. The agreement between the model and the observed SED, polarisation and spectroastrometric signature of beta CMi confirms that the discs around Be stars are well modelled as viscous decretion discs.

Phenotypic Association between the Outer Membrane Protein OmpW and the Small Multi-Drug Resistance Protein EmrE in Escherichia coli

description: In Escherichia coli, the small multidrug resistance (SMR) transporter protein EmrE confers host resistance to a broad range of toxic quaternary cationic compounds (QCCs) via proton motive force in the cytoplasmic membrane. Biologically produced QCCs also act as EmrE osmoprotectant substrates within the cell and participate in host pH regulation and osmotic tolerance. Although E. coli EmrE is one of the most well-characterized SMR members, it is unclear how the substrates that it transports into the periplasmic space escape across the outer membrane (OM) in Gram-negative bacteria. We tested the hypothesis that E. coli EmrE relies on an unidentified OM protein (OMP) to complete the extracellular release of its QCC. By conducting pH-based phenotypic growth screens, complementation and methyl viologen (MV) resistance assays, we have confirmed that EmrE relies on the presence of an OMP, specifically OmpW, to complete its extracellular substrate efflux across the OM.

description: The decline in conventional hydrocarbon resources coupled with the increase in energy demand has encouraged the development of unconventional resources such as gas-hydrate reservoirs and shale/tight formations. The understanding and analysis of the factors that affect the performance of these reservoirs are critical for their efficient exploitation. Mathematical models are widely used to analyse conventional reservoirs. However, development of such models for unconventional reservoirs is complex, due to the non-linearity of the governing equations. These non-linearities may originate from different sources such as: phase change due to hydrate dissociation in gas-hydrate reservoirs, pressure dependence of permeability, variable gas compressibility, saturation changes during two-phase flow, to name a few. The main objective of this work is to develop some mathematical models for these unconventional reservoirs. The focus will be on two specific types of unconventional resources; namely (1) gas-hydrate reservoirs and (2) tight formations. In the first part of this study, the various governing equations of ﬂuid ﬂow, heat transfer, thermodynamics and kinetics of hydrate decomposition, which are all integral to gas production from hydrate reservoirs, are solved simultaneously to develop two predictive models to forecast the performance of flat and tilted hydrate reservoirs. Furthermore, a material balance equation was developed for hydrate-capped gas reservoir. For this purpose, an effective gas deviation factor, Z*, analogous to Z, was defined such that the traditional p/Z analysis technique could be used to estimate OGIP from production data. In the second part of this study, a methodology was developed for modeling the non-linear diffusivity equations. Rather than using a distance of investigation equation, which can be problematic in complex flow geometries, a “volume of investigation” was used. The applicability of this technique for stress-sensitive formations and tight/shale gas reservoirs was explored through a new implementation of pseudotime. The solution developed is valid during transient, boundary-affected and boundary-dominated flow. Moreover, a theoretical basis was established to understand the behavior of tight oil reservoirs during the transient flow period, including the effect of saturation and relative permeability changes, and the highly non-linear two-phase flow equations were analyzed and solved analytically.

description: The quantum relativistic Buneman instability is investigated theoretically using a collective Klein-Gordon model for the electrons and a cold fluid model for the ions. The growth rate and unstable wave spectrum is investigated in different parameter regimes corresponding to various degrees of relativistic and quantum effects. The results may be important for streaming instabilities involving ion dynamics in very dense plasmas.

description: Статья на примере голливудского фильма «Тебе конец» (2011 г.) анализирует образ дома как фундаментальный принцип организации городской цивилизации. В традиции американских фильмов ужасов сформировался особый кинонарратив дома, повествующий о сакральных и имущественных принципах оседлости в границах современных городов. Американский фильм ужасов экзистенциально насыщает образ дома, концентрируя в нем драматическое ощущение человеком своей обездоленности и фактического отсутствия Родины. Дом как значимый голливудский хоррор-символ выступает патриотической рефлексией человека, трагически утратившего архетипические чувства коллективного целого, принадлежности к культурной памяти и связи с социальной общностью. Сюда же примешивается комплекс ужасных смыслов, связанных с кризисом семейно-родовых способов воспроизводства повседневности. Дом выступает ведущим символом разрушения интимности предметной среды, которая в цивилизационном контексте повсеместно прочитывается лишь как имущественное отношение. Визуализация и сакрализация этой темы становится одним из значимых и повсеместно идеологизируемых сюжетов в традиции американских фильмов ужасов.
