description: The separation of the Milky Way disk into a thin and thick component is supported by differences in the spatial, kinematic and metallicity distributions of their stars. These differences have led to the view that the thick disk formed early via a cataclysmic event and constitutes fossil evidence of the hierarchical growth of the Milky Way. We show here, using N-body simulations, how a double-exponential vertical structure, with stellar populations displaying similar dichotomies can arise purely through internal evolution. In this picture, stars migrate radially, while retaining nearly circular orbits, as described by Sellwood & Binney (2002). As stars move outwards they populate a thickened component. Such stars found at the present time in the solar neighborhood formed early in the disk's history at smaller radii where stars are more metal-poor and alpha-enhanced, leading to the properties observed for thick disk stars. Classifying stars as members of the thin or thick disk by either velocity or metallicity leads to an apparent separation in the other property as observed. This scenario is supported by the SDSS observation that stars in the transition region do not show any correlation between rotational velocity and metallicity. The good qualitative agreement between our simulation and observations in the Milky Way hint that the thick disk may be a ubiquitous galaxy feature generated by stellar migration. Nonetheless, we cannot exclude that some fraction of the thick disk is a fossil of a past more violent history, nor can this scenario explain thick disks in all galaxies.

description: We present a broad class of states which are diagonal in the basis of N-qubit GHZ states such that non-positivity under the partial transpose operation is necessary and sufficient for the presence of entanglement. This class includes many naturally arising instances such as dephased or depolarised GHZ states. Furthermore, our proof directly leads to an entanglement witness which saturates this bound. The witness is applied to thermal GHZ states to prove that the entanglement can be extremely robust to system imperfections.

Microenvironmental Transthyretin Amyloid Fibrils Alter Cardiac Fibroblast Structure and Function

description: According to the official reports of the American Heart Association, cardiac diseases are and have been the leading cause of death in the United States during recent years. One disease is infiltrative cardiomyopathy with deposition of abnormal material in the heart tissue, which alters the physiological function and structure of the ventricular walls in one quarter of elderly men and women. However, this wild type transthyretin amyloidosis (wtATTR) is an underappreciated cause of this pathological condition. Animal models for this amyloid disease do not exist, thus in this study, bioengineering approaches have been used to design an in vitro model for this disease, which was exploited to evaluate the main effects and the response at the cellular level to the presence of amyloid TTR. The model is composed of neonatal rat ventricular fibroblasts (NRVFs) cultured on soft polyacrylamide (PA) gel, with stiffness of 10 kPa and stiff glass or plastic (> 1 GPa) coated with a deposited layer of transthyretin amyloid fibrils. Different protein expression and distribution, along with proliferation, adhesion and migration of NRVFs have been qualitatively and quantitatively evaluated with or without the presence of TTR using substrates of different stiffness. To date, there are no studies reporting the behavior of isolated fibroblasts when exposed to TTR fibrils making my study the first. My most significant novel findings for cardiac fibroblasts grown in culture on deposited TTR fibrils are (1) enhanced proliferation rate, (2) the increased migration velocity and (3) the reorganization of the actin cytoskeleton. (1) Increased reduction of MTS tetrazolium by a colorimetric assay suggests a TTR-related increase in the proliferation rate of cells. (2) Barrier removal tests after confluence and single cell live imaging resulted in faster migration velocity of fibroblasts cultured on TTR fibrils. Indeed, two independent methods have been used to evaluate the migration velocity of these cells, both resulting in a faster velocity on TTR-coated substrates. (3) The organization of the actin cytoskeleton within the cells depended on the presence of TTR, in fact actin stress fibers presented a less polarized orientation and a preferential distribution to the borders of the cell when cultured on TTR. I conclude that many of the fibroblast features have been modified by TTR, in some cases very significantly while in others less, both at the structural and functional level. Further studies using different analytical approaches might help in deepening the comprehension of the causes and the mechanisms underlying the pathological adaptation of cells to transthyretin, opening pathways for the development of more realistic in vitro models and subsequently to the discovery of new therapeutic targets, diagnostic instruments and prevention techniques.
Exploring the effect of microtubule domains and various microtubule associated proteins on cellulose synthase complex velocity for determining anisotropic growth in Arabidopsis thaliana
Creators: name: Mulvihill, Adam
Publisher: name: University of British Columbia
Year: 2017

description: Previous research with anisotropy mutants, any1 and mor1-1, deficient in cellulose production and microtubule disruption respectively, linked the velocity of the cellulose synthase complex (CSC) to the crystalline structure of microfibrils in the wall for maintaining anisotropy during rapid elongation at elevated temperatures. CSCs have been visualized as being functional inside and outside of these microtubule domains and, in mor1-1, it was observed that increased CSC tracking outside of microtubule domains may be the means by which anisotropy fails due to correlations with increased CSC velocity and crystallinity. We hypothesized based on these findings that microtubule association with the plasma membrane, spatial organization, and polymerization status may have a significant effect on CSC velocity and anisotropy in a variety of backgrounds and/or drug treatments. We explored the concurrent visualization of YFP-CESA6 labeled cellulose synthase complexes with RFP-TUB6 labeled microtubules with variable angle total internal reflectance fluorescence (near-TIRF) microscopy. Not all genotypes had the proper RFP-TUB6 constructs, limiting our assessment to the same degree as previous research. This allowed for a more comprehensive analysis of CSC movement and velocity due to its increased resolution at specific optical sections. By comparing the results obtained from live-cell imaging with near-TIRF microscopy between a number of anisotropy-compromised mutants, such as any1, mor1-1, bot1, and oryzalin-treated seedlings, and microtubule-associated protein (MAP) genotypes with either enhanced (RIC1-OX) or non-specific anisotropy defects (clasp-1), we were able to obtain a more accurate depiction of the extent of microtubule influence on CSC activity. From these results, we were able to consider potential effects of microtubules on plasma membrane domains on CSC velocity during rapid elongation, as well as to discern potential new roles and effects of the MOR1 protein. Analysis of oryzalin-treated seedlings compared to the severely impaired double mutant, any1/mor1-1, provided us with an awareness that the mechanisms controlling CSC activity are complex. With this understanding, our exploration into the effect of several MAPs on CSC velocity highlighted that microtubule polymerization and organization do not hold equal weight, and that a potential standard exists for CSC velocity and wall crystallinity, as exemplified in wild type and RIC1-OX lines.

Analysis of Cognitive and Keyword-based Approaches for Searching Judicial Documents

description: Searching and retrieving information efficiently represents an urgency in both ordinary and business tasks. With the introduction of high-performance storage systems and cloud tech- nologies, reporting on paper sheets resulted an obsolete practice. Hence, companies aimed at reducing this type of operations to digital processes, employing digital repositories to store files in order to gain in availability and resilience. In this situation, software that provide functionalities to allow direct and valid access to stored data are referred to as search engines. Aiming at analyzing cognitive and keyword-based searching algorithms, the goal of this dissertation is to develop a domain-specific search engine capable to combine the two cited approaches. The rationale behind adopting these two techniques together has to be found in the necessity to overcome the lack of ’query context’ and ’intent understanding’, along with the inefficiency of common procedures in handling equal words carrying diverse meanings. To meet the desired objectives, Text Retrieval was carried out on a juridical domain by performing the search on a corpus of authentic legal documents from the Italian Court of Cassation. We organized our work into two core activities: Document Processing and Text Retrieval, both integrated in the Search Engine pipeline. In particular, Text Retrieval has been per- formed on top of processing units expressly built for granting proper answers to literal and non-literal queries. During the Document Processing phase, significant effort has been destined to extracting texts from actual judicial documents, initially in the form of images of scanned documents. Text Retrieval, instead, concerned with the realization of a search engine pipeline featuring diverse Deep Learning approaches. Such techniques involved the encoding of text portions into a more furbished representation by capturing both syntactic and semantic word features. Finally, the considered embedding approaches are compared by collecting the answers to specific questionnaires given to a random sample of people with the purpose of validating our approaches in a concrete use-case scenario.

description: We present mid infrared (Mid-IR) spectra of the Compton-thick Seyfert 2 galaxy NGC\,3281, obtained with the Thermal-Region Camera Spectrograph (T-ReCS) at the Gemini South telescope. The spectra present a very deep silicate absorption at 9.7\,$μ$m, and [S{\sc\,iv]}\,10.5\,$μ$m and [Ne{\sc\,ii]}\,12.7\,$μ$m ionic lines, but no evidence of PAH emission. We find that the nuclear optical extinction is in the range 24 $\leq$ A$_{V}$ $\leq$ 83\,mag. A temperature T = 300\,K was found for the black-body dust continuum component of the unresolved 65\,pc nucleus and at 130\,pc SE, while the region at 130\,pc reveals a colder temperature (200\,K). We describe the nuclear spectrum of NGC\,3281 using a clumpy torus model that suggests that the nucleus of this galaxy hosts a dusty toroidal structure. According to this model, the ratio between the inner and outer radius of the torus in NGC\,3281 is $R_0/R_d$ = 20, with {\bf 14} clouds in the equatorial radius with optical depth of $τ_{V}$ = 40\,mag. We would be looking in the direction of the torus equatorial radius ($i$ = {\bf 60$^{\circ}$}), which has outer radius of R$_{0}\,\sim$ 11\,pc. The column density is N$_{H}\approx$\,{\bf 1.2}\,$\times\,10^{24}\,cm^{-2}$ and iron K$α$ equivalent width ($\approx$ 0.5 - 1.2\,keV) are used to check the torus geometry. Our findings indicate that the X-ray absorbing column density, which classifies NGC\,3281 as a Compton-thick source, may also be responsible for the absorption at 9.7\,$μ$m providing strong evidence that the silicate dust responsible for this absorption can be located in the AGN torus.

The salience of nationalism and economic polarization : long term trends and electoral dynamics
Creators: name: Lachance, Sarah
Publisher: name: University of British Columbia
Year: 2016

description: This research explores the relationship between ethnic cleavages and the class cleavage with data from the Comparative Manifesto Project (CMP) on liberal democracies from 1945 to 2015. According to the “freezing” thesis of Lipset & Rokkan (1967: 12), multinational countries have developed a weaker class cleavage because of anterior territorial-cultural cleavages. In the first part of the data analysis, multinational countries are compared against others on the two variables used to measure these cleavages: the salience of nationalism and economic polarization. Multinational countries show a higher salience of nationalism, as expected, and lower economic polarization. The second part of the data analysis addresses the relationship between the salience of nationalism and economic polarization in multinational countries. The regression analysis offers a dynamic account of the relationship between these variables across elections. The contextual model, also called “within-between random effects model” (REWB), explicitly models cross-country heterogeneity by separating them from within-country variance, which allows the disentanglement of long-term effects at the country level from short-term effects at the election level. The hypothesized negative relationship between the salience of nationalism and economic polarization holds at both hierarchical levels until the new democracies of the 90s are controlled for, which are confounding the effect of the country-level nationalism variable. However, the negative effect of nationalism on economic polarization remains stable at the election level. This thesis contributes to the scholarship stemming from Lipset & Rokkan’s (1967) by accounting for the short-term effect of the salience of ethnic cleavages on economic polarization at the election level.
"Money Talks, Wealth Whispers" Real Housewives’ Legacy: Class Ambivalence and Emotional Camping
Creators: name: Psarras, Evie

Year: 2020
Subjects: Uncategorized

description: Real Housewives (RH) is a global reality television franchise comprised of seven series in the United States. Dedicated to showcasing highly-feminized women, wealth, and materialism, RH gained prominence throughout the Great Recession. Since RH reached phenomenal status in popular culture at a time of economic insecurity and class resentment, I wondered what it might be communicating about class in the U.S. This research is grounded by a three-pronged approach to media, which includes textual analysis of media content, discussion of production, and audience reception (Kellner, 2011). To fulfill this methodological approach, I interviewed insiders and show producers to understand production of RH. I conducted a cross-platform analysis of RH content including: (i) a comprehensive frame analysis of all seven series across time, from the first season to the most recent, and (ii) a discourse analysis of select women’s Instagram accounts to study agency and resistance to production. To study reception, I conducted interviews with 26 fans of RH. Finally, I interviewed eight former cast members of RH, which supports triangulation of findings from the framing, discourse, and interview analysis of fans and producers. Findings show that: 1) The series frames the women to align with people’s ambivalent ideas about social class. 2) The media frames aim to resolve viewers to the status quo. 3) the women’s self-presentation online is representative of a mediatized branded-ideal, grounded in a gendered and classist neoliberalism, which works to reinforce beliefs in class advancement. 4) The women on the series engage in a particular type of labor across platforms, conceptualized here as emotional camping, which empowers them with a pathway to privacy in a highly public career. 5) Fans resist dominant ideas by creating meaningful interpretations and practices around viewing that celebrate the women of RH. The most comprehensive analysis of RH to date, this work introduces an inventive strategy for studying reality TV, and is one of the first studies to look at its long-term cultural imprint. It is also one of the first works to study the subversive class-based ideologies in the ordinary personas proliferating media since the turn of the millennium.

description: The calculation of Yukawa couplings in F-theory GUTs is developed. The method is applied to the top and bottom Yukawa couplings in an SU(5) model of fermion masses based on family symmetries coming from the SU(5)_\perp factor in the underlying E(8) theory. The remaining Yukawa couplings involving the light quark generations are determined by the Froggatt Nielsen non-renormalisable terms generated by heavy messenger states. We extend the calculation of Yukawa couplings to include massive states and estimate the full up and down quark mass matrices in the SU(5) model. We discuss the new features of the resulting structure compared to what is usually assumed for Abelian family symmetry models and show how the model can give a realistic quark mass matrix structure. We extend the analysis to the neutrino sector masses and mixing where we find that tri-bi-maximal mixing is readily accommodated. Finally we discuss mechanisms for splitting the degeneracy between the charged leptons and the down quarks and the doublet triplet splitting in the Higgs sector.

Ribbit and Racket: The Effects of Anthropogenic Noise on Anuran Calling Behavior in the Chicago Region
Creators: name: Bielinski, Nolan K
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Anthropogenic noise represents a major obstacle to anurans in urban landscapes because they rely heavily on vocalizations to find breeding grounds, choose mates, and settle territorial disputes. A large proportion of urban frogs may be affected by noise, as past research suggests that road-side wetlands are a major contribution to frog biodiversity and migration ability in developed landscapes. Thus, there is a need for improved monitoring and research techniques for studying anurans in urban habitats so we can better understand and mitigate the effects of noise on the ecology, behavior, and physiology of frogs. My dissertation uses soundscape methods to achieve the following: (Chapter 1) Improve how automated data collection is used in urban frog call surveys. (Chapter 2) Conduct population-level noise playback experiments to investigate how patterns in call attributes change across species, genera, and natural history characteristics. (Chapter 3) Compare results for individual-level versus population-level noise playback experiments. For my public defense, I will discuss the community-level playback study (Chapter 2). I conducted a total of 155 playback experiments on nine anuran species across 32 breeding sites around the greater Chicago region. I investigated whether patterns in call attributes (call rate, dominant frequency, call length, and pulse rate) follow taxonomic or natural history characteristics. I also tested whether the anthropogenic noise source (cars, airplanes, or trains), or the magnitude of noise level (peaks of 70, 80, or 90 dB) affected behavioral responses. I detected multivariate clustering by genus and species but not by natural history characteristics. I found notable consistency in the changes to call rate, as eight species reduced their call rate. This type of consistency has not been detected across species from past publications. The only species not to reduce call rate was also the only one to increase dominant frequency, suggesting that these are two mutually exclusive strategies for dealing with anthropogenic noise. I did not detect major patterns in call length or pulse rate changes. I also did not see consistent changes between the different noise sources, indicating that our populations were unable to perceive differences in anthropogenic noise sources and act differently as a response. For noise magnitude, most behavioral changes occurred in the 90 and 80 dB treatments, indicating that noise may only be affecting calling behavior in the loudest habitats, such as roadside ditches and retention ponds. Considering that artificial ponds contribute considerably to the biodiversity and dispersal ability of frogs in urban landscapes, noise pollution should be a concern for conservationists.

description: We have selected the Galactic HII region M43, a close-by apparently spherical nebula ionized by a single star (HD37061) to investigate several topics of recent interest in the field of HII regions and massive stars. In a series of two papers we perform a combined, comprehensive study of the nebula and its ionizing star by using as many observational constraints as possible. We collected for this study a set of high-quality observations, including the optical spectrum of HD37061, along with nebular optical imaging and long-slit spatially resolved spectroscopy. The first part of our study comprises a quantitative spectroscopic analysis of the ionizing star, and the empirical analysis of the nebular images and spectroscopy. We determine the stellar parameters of HD37061 and the total number of ionizing photons emitted by the star. We find observational evidence of the presence of scattered light from the Huygens region (brightest part of the Orion nebula) in the M43 region. We show the importance of an adequate correction of this scattered light from the imagery and spectroscopic observations of M43 for a proper determination of the total nebular H_alpha luminosity, the nebular physical conditions and chemical abundances. We perform a detailed nebular empirical analysis of 9 apertures extracted from a long-slit located to the west of HD37061, obtaining the spatial distribution of the physical conditions and ionic abundances. For three of the analyzed elements (O, S, and N) we could determine total abundances directly from observable ions (no ionization correction factors were needed). The comparison of these abundances with those derived from the spectrum of the Orion nebula indicates the importance of the atomic data and, specially in the case of M\,42, the considered ionization correction factors.

description: We study magnetically ordered phases and their phase boundaries in the $J_1-J_2-J_3$ Heisenberg models on the honeycomb lattice using series expansions around Néel and different colinear and non-colinear magnetic states. An Ising anisotropy ($λ=J_{\perp}/J_z\ne 1$) is introduced and ground state energy and magnetization order parameter are calculated as a power seies expansion in $λ$. Series extrapolation methods are used to study properties for the Heisenberg model ($λ=1$). We find that at large $J_3$ ($>0.6$) there is a first order transition between Néel and columnar states, in agreement with the classical answer. For $J_3=0$, we find that the Néel phase extends beyond the region of classical stability. We also find that spiral phases are stabilized over large parameter regions, although their spiral angles can be substantially renormalized with respect to the classical values. Our study also shows a magnetically disordered region at intermedaite $J_2/J_1$ and $J_3/J_1$ values.

description: Noncolliding diffusion processes reported in the present paper are $N$-particle systems of diffusion processes in one-dimension, which are conditioned so that all particles start from the origin and never collide with each other in a finite time interval $(0, T)$, $0 < T < \infty$. We consider four temporally inhomogeneous processes with duration $T$, the noncolliding Brownian bridge, the noncolliding Brownian motion, the noncolliding three-dimensional Bessel bridge, and the noncolliding Brownian meander. Their particle distributions at each time $t \in [0, T]$ are related to the eigenvalue distributions of random matrices in Gaussian ensembles and in some two-matrix models. Extreme values of paths in $[0, T]$ are studied for these noncolliding diffusion processes and determinantal and pfaffian representations are given for the distribution functions. The entries of the determinants and pfaffians are expressed using special functions.

Wandering within, against, and beyond the pathways of science education : towards heeding the call of Indigenous science
Creators: name: Higgins, Marc
Publisher: name: University of British Columbia
Year: 2016

description: Often within science education, Indigenous science is either excluded or included in ways that differ from or defer its intended meanings, as well as its pedagogical potentiality for all students. The central question that guides this dissertation is How is Indigenous science to-come with/in the context of science education? This dissertation draws from decolonizing, post-colonial, post-structural, and post-humanist theory-practices to address ‘to-come’ in three ways: a) Indigenous science on its own terms as not-yet and still-to-come with/in science education; b) Indigenous science as a relationship whose indeterminate arrival invites re(con)figuring of the lived constructs, concepts, and categories of science education; and c) practices (including pedagogy) that might allow for and nurture the possibility of Indigenous science to-come in its second iteration. To explore this triple(d) understanding of ‘to-come’, each chapter within the dissertation acts as an excursion through a path of science education. Journeying involves strategically straying off the beaten path or tactically taking the pathway in unintended ways to lose sight of the prescriptive and often problematic ways in which the path is regularly travelled. Further, each journey is iterative, travelling through, against, and/or beyond a particular path, wherein the learning is enfolded and carried forward into the next trip. Equipped with a plethora of deconstructive tools, science education is (re)opened through (re)considering its: a) oppositional, dialectic nature; b) critical modes as protective, rather than productive, of the status quo (i.e., through mirrored correspondence); c) ontological taken-for-grantedness (e.g., through its a priori and singular positioning); and, d) responsibility, as well as ability to respond. In response, I offer a call and analytical frames for: a) dialogue; b) critique as prismatic and diffractive; c) ontological plurality and co-constitutiveness; as well as, d) response-ability, respectively. Insights produced and scholarly contributions from wandering include: a) an exploration of curricular alternatives to scientific literacy, notably Karen Barad’s agential literacy and Gregory Cajete’s ecologies of relationships; b) re(con)figuring visual pedagogies to engage in decolonizing science education. This theory-practice bridging pursues design of a pedagogy of relationally storying nature well positioned to account for and be accountable to Indigenous science to-come.
The Role of the Supplemental Nutrition Assistance Program in Food Insecurity and Food Acquisitions

description: Given the size of SNAP in both households served and public dollars spent, it is of great importance to understand the impact of SNAP dollars and how they affect households. Food insecurity and diet quality have potential impact on our health care system and economy. This dissertation looks at some of the most vulnerable SNAP households – those near the $0 net income threshold for maximum SNAP benefits – using the Household Food Acquisition and Purchase Survey (FoodAPS), collected in 2012 to early 2013, in a fuzzy regression kink framework using net income as an instrument, as well as descriptive analyses. First stage findings indicate that net income based on household-reported survey data does not perfectly fit expectations for SNAP benefit allotment, implying that current household economic status does not necessarily match status at time of application. This is as expected since the measure of net income used here is not collected at the time of SNAP benefit application. However, households with positive net income do receive lower benefit amounts with higher net income, though the slope is less steep than predicted by the benefit allotment calculation. I examine the effect of SNAP benefit amount on three outcomes: food insecurity, food spending, and nutritional quality. I am unable to reject no effect of SNAP benefit amount on any outcome in this subpopulation. However, in these households food insecurity remains high and nutritional quality does not meet national recommendations. Additionally, households with negative net income are, as we might expect, worse off – they are more likely to struggle to pay important bills on time. However, they are also less likely to turn to places of worship for food support. I also find suggestive evidence that nutritional quality is improved by SNAP benefit amount particularly in week 3 after receiving SNAP benefits. This research suggests that the SNAP benefit formula is not harmful, but further that if SNAP goals are to be met, policies may need to increase benefits for all households. Further work should focus on the effects of increased benefit amounts among a larger portion of the SNAP population.

description: This essay analyzes Richard Powers’s The Overstory (2018), a novel that ostensibly demands an eco-critical reading, under the lens of neurodiversity. Focusing on the idiosyncrasies of sensory perception in autism, the essay explores the atypical engagement with the more-than-human that neurodiversity (and specifically autism) fosters—a kind of engagement that deeply destabilizes neuro-normative, human-centered subjectivity, opening up to more egalitarian ways of relation with the environment. In a novel populated by neurodivergent characters with a keen ecological sensibility, Powers comes close to imagining this kind of non-hierarchical connection with the natural world. The essay explores how neurodiversity works in the novel at a characterological, thematic, and structural level, functioning as a bridge between human and non-human scales. In this way, neurodiversity finely glosses and articulates the kind of animistic, environmental message that Powers instils in his Pulitzer prize winning novel.

description: In memory of Marcos Moshinsky, who promoted the algebraic study of the harmonic oscillator, some results recently obtained on an infinite family of deformations of such a system are reviewed. This set, which was introduced by Tremblay, Turbiner, and Winternitz, consists in some Hamiltonians $H_k$ on the plane, depending on a positive real parameter $k$. Two algebraic extensions of $H_k$ are described. The first one, based on the elements of the dihedral group $D_{2k}$ and a Dunkl operator formalism, provides a convenient tool to prove the superintegrability of $H_k$ for odd integer $k$. The second one, employing two pairs of fermionic operators, leads to a supersymmetric extension of $H_k$ of the same kind as the familiar Freedman and Mende super-Calogero model. Some connection between both extensions is also outlined.

description: In Japanese culture, the beauty ideal is holistically expressed in three images, three historical and cultural symbols: the charm of things (mono no aware), intimate beauty (yugen), and the beauty of lonely sadness (wabi-sabi). These concepts are the core of Japanese aesthetics, poetics, worldview, and outlook. This article reveals the characteristics of these aesthetic categories in the literature and analyzes the interpretation of the traditional aesthetic mono no aware, yugen, and wabi-sabi. The system of images, on the basis of which the authors create their understanding of the category of beauty, is made up of household items and interior decoration, writing materials, and other utensils. In such an unusual way, the author's embodiment of the traditional idea of the relationship between art and everyday life, when aesthetic principles determine the way of life, is obtained. According to the aesthetic concept of Japanese culture, the essence of beauty consists not so much in the result of pleasure from its contemplation but in the process of comprehending it, familiarizing with it. Emotional enrichment and spiritual elevation are the true essences of the mono no aware, yugen, and wabi-sabi symbols.

description: Even though the dark-matter power spectrum in the absence of biasing predicts a number density of halos n(M) ~ M^-2 (i.e. a Schechter alpha value of -2) at the low-mass end (M < 10^10 M_solar), hydrodynamic simulations have typically produced values for stellar systems in good agreement with the observed value alpha ~ -1. We explain this with a simple physical argument and show that an efficient external gas-heating mechanism (such as the UV background included in all hydro codes) will produce a critical halo mass below which halos cannot retain their gas and form stars. We test this conclusion with GADGET-2-based simulations using various UV backgrounds, and for the first time we also investigate the effect of an X-ray background. We show that at the present epoch alpha is depends primarily on the mean gas temperature at the star-formation epoch for low-mass systems (z

description: Networks are a natural and popular mechanism for the representation and investigation of a broad class of systems. But extracting information from a network can present significant challenges. We present NetzCope, a software application for the display and analysis of networks. Its key features include the visualization of networks in two or three dimensions, the organization of vertices to reveal structural similarity, and the detection and visualization of network communities by modularity maximization.

“They’re not going to Stop us from Trusting our Faith”: School Experiences of Arab American Muslim Women
Creators: name: Khayr, Layla W
Publisher: name: University of Illinois at Chicago

description: Abstract Muslim Arab women in the United States experience anti-Muslim and anti-Arab racism resulting in discomfort in the educational setting; they navigate a world in which they are perceived as terrorists due to images in the media. Furthermore, discriminatory experiences at school impact the adolescent identity and racial and ethnic identity development of Arab Muslim youth. Although some research attempts to examine the link between adolescent identity and school experiences, limited studies about Arab Muslims are present in the literature and only a few studies explore the discriminatory experiences of Arab Muslims in schools. This study explores the racialized high school experiences of Arab Muslim women in the Chicagoland area as well as the resources they sought, utilized, or found helpful. Fourteen young adult women between the ages of 18 and 23 were interviewed about their retrospective high school experiences. Semi-structured qualitative interviews were conducted, and information was obtained regarding their demographics, school and community experiences, the resources that were available to them, and the resources they recommend for the future. Participants in this study experienced a wide range of tribulations within their schools and communities due to the constantly changing sociopolitical landscape. However, they also demonstrate immense strength and agency in coping with, responding to, and challenging these experiences. Several themes emerged from the data highlighting the agency of these women and how they make choices in their daily lives as they navigate racialized society. The themes fall within four categories: identity, community norms and expectations, anti-Muslim and anti-Arab racism and discrimination, and school experiences and resources. Implications include guidelines for fostering identity development, understanding community norms and expectations within school settings, and recommendations for school resources.
