A simple model for the distribution of quiet Sun magnetic field strengths
Creators: name: Almeida, J. Sanchez
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We derive a first order linear differential equation describing the shape of the probability density function of magnetic field strengths in the quiet Sun (PDF). The modeling is very schematic. It considers convective motions which continuously supply and withdraw magnetic structures. In addition, a magnetic amplification mechanism increases the field strength up to a threshold that cannot be exceeded. These three basic ingredients provide PDFs in good agreement with the PDFs produced by realistic numerical simulations of magneto convection, as well as with quiet Sun PDFs inferred from observations. In particular, the distribution is approximately lognormal, and it produces an excess of magnetic fields (i.e., a 'hump' in the distribution) right before the maximum field strength. The success of this simple model may indicate that only a few basic ingredients shape the quiet Sun PDF. Our approach provides a concise parametric representation of the PDF, as required to develop automatic methods of diagnostics.

description: We recently described a general solution to the phase matching problem that arises when one wishes to perform an arbitrary number of nonlinear optical processes in a single medium [PRL 95 (2005) 133901]. Here we outline in detail the implementation of the solution for a one dimensional photonic quasicrystal which acts as a simultaneous frequency doubler for three independent optical beams. We confirm this solution experimentally using an electric field poled KTiOPO$_4$ crystal. In optimizing the device, we find - contrary to common practice - that simple duty cycles of 100% and 0% may yield the highest efficiencies, and show that our device is more efficient than a comparable device based on periodic quasi-phase-matching.

description: We present an efficient numerical solution of the DGLAP equations for single and double parton distribution functions (PDFs and DPDs), based on the Chebyshev interpolation of these functions. For PDF evolution, our method allows for a higher numerical accuracy using a considerably smaller number of grid points compared to other methods. The DPD evolution is realized using an affordable number of grid points, and allows for two independent renormalization scales for the two partons. Both methods include NNLO DGLAP kernels and flavor matching.

description: The $K^-pp$ system is investigated using a variational approach with realistic two-body interactions: the Argonne v18 $NN$ potential and an energy dependent $\bar{K}N$ effective interaction derived from chiral SU(3) coupled-channel dynamics. Uncertainties in subthreshold extrapolations of the $\bar{K}N$ interaction are considered. A weakly bound $K^-pp$ state is found, with a binding energy $B = (19\pm 3)$ MeV substantially smaller than suggested in previous calculations. The decay width $Γ(K^-pp\to πΣN)$ is estimated to range between about 40 and 70 MeV.

Influence of Lorentz violation on Dirac quasinormal modes in the Schwarzschild black hole spacetime

description: Using the third-order WKB approximation and monodromy methods, we investigate the influence of Lorentz violating coefficient $b$ (associated with a special axial-vector $b_μ$ field) on Dirac quasinormal modes in the Schwarzschild black hole spacetime. At fundamental overtone, the real part decreases linearly as the parameter $b$ increases. But the variation of the imaginary part with $b$ becomes more complex. For the larger multiple moment $k$, the magnitude of imaginary part increases with the increase of $b$, which means that presence of Lorentz violation makes Dirac field damps more rapidly. At high overtones, it is found that the real part of high-damped quasinormal frequency does not tend to zero, which is quite a different from the symptotic Dirac quasinormal modes without Lorentz violation.

Revelations of the flesh and testimonies of desire : Sebatino del Piobo’s "Martyrdom of Saint Agatha"
Creators: name: Seekins, Sandra
Publisher: name: University of British Columbia
Year: 2009

description: In 1520 Sebastiano del Piombo completed the painting the Martyrdom of Saint Agatha for his patron Cardinal Ercole Rangone. Scholarly discussions of this image indicate that struggles to describe it are caught up in an imposed artificial division between the erotic and the sacred. However, as my analysis of the painting will make clear, there is no stable separation between the secular and the sacred in visual imagery of the sixteenth century. In the Martyrdom of Saint Agatha, erotic and spiritual interests cannot be separated, but are codependent within the multivalent possibilities articulated. My argument derives from the image itself, and in particular from an analysis of the artistic traditions employed and early sixteenth-century attitudes toward the body and erotic tropes. Two established visual modes are conflated in the painting: the tradition of the Venetian nude and the tradition of the monumental muscular female figure associated with Michelangelo. The salvific resonance of Christ's body, related to all saints' bodies, is also an important aspect of the painting. In the case of a female saint, a conflict is played out between the idea that holy women have "become male," and practices from female piety in which women associate their own corporeality with Christ's suffering flesh. The gender ambiguity of Saint Agatha - the result of the blurring of visual traditions, her connection to the body of Christ, and the "becoming male" theory, is also related to ideas about androgyny and hermaphroditism. Sebastiano del Piombo's Martyrdom of Saint Agatha problematizes gender, erotic, sacred, passive, and active categories. In the Renaissance, it offered a complex type of viewing pleasure, and its viewers participated in the formation of its potential meanings.

description: Tiny object classification problem exists in many machine learning applications like medical imaging or remote sensing, where the object of interest usually occupies a small region of the whole image. It is challenging to design an efficient machine learning model with respect to tiny object of interest. Current neural network structures are unable to deal with tiny object efficiently because they are mainly developed for images featured by large scale objects. However, in quantum physics, there is a great theoretical foundation guiding us to analyze the target function for image classification regarding to specific objects size ratio. In our work, we apply Tensor Networks to solve this arising tough machine learning problem. First, we summarize the previous work that connects quantum spin model to image classification and bring the theory into the scenario of tiny object classification. Second, we propose using 2D multi-scale entanglement renormalization ansatz (MERA) to classify tiny objects in image. In the end, our experimental results indicate that tensor network models are effective for tiny object classification problem and potentially will beat state-of-the-art. Our codes will be available online https://github.com/timqqt/MERA_Image_Classification.

description: A measurement of the inclusive top quark-antiquark pair production cross section in proton proton collisions at a centre-of-mass energy of 13 TeV is used by the CMS experiment, together with the theoretical prediction at next-to-next-to-leading order, to determine the top quark mass and to extract a value of the strong coupling constant with different sets of parton distribution functions. Dilepton events are selected and the cross section is measured from a likelihood fit to the final state distributions. The dependence of the measured cross section on the assumption on the top quark mass parameter in the POWHEG simulation is mitigated by including this parameter in the fit. The top quark mass is extracted in the pole and running mass schemes.

description: Let X be a finite set of complex numbers and let A be a normal operator with spectrum X that acts on a separable Hilbert space H. Relative to a fixed orthonormal basis e_1,e_2, ... for H, A gives rise to a matrix whose diagonal is a sequence d=(d_1,d_2,...) with the property that each of its terms d_n belongs to the convex hull of X. Not all sequences with that property can arise as the diagonal of a normal operator with spectrum X. The case where X is a set of real numbers has received a great deal of attention over the years, and is reasonably well (though incompletely) understood. In this paper we take up the case in which X is the set of vertices of a convex polygon in the complex plane. The critical sequences d turn out to be those that accumulate rapidly in X in the sense that $$ \sum_{n=1}^\infty {\rm{dist}} (d_n,X)

description: ZUSAMMENFASSUNG Der Prozess der Bestäubung stellt einen wichtigen Abschnitt in der sexuellen Vermehrung höherer Pflanzen dar und ist auch essentiell für das Verständnis der Vielfalt der Blütenpflanzen. Darüber hinaus wird der Bestäubungsbiologie aufgrund der aktuellen Diskussionen rund um das Bienensterben eine besondere Aktualität beigemessen. Eine Erforschung der Schülervorstellungen zu diesem Thema ist somit von großem fachdidaktischem Interesse. In der vorliegenden qualitativen Studie wurden deshalb Schülervorstellungen von sieben Schüler_innen der 5. Schulstufe zur Bestäubungsbiologie mithilfe von leitfadenorientierten Interviews erhoben und in einer qualitativen Inhaltsanalyse ausgewertet. Die Ergebnisse zeigen, dass Lernende nur mangelhaft zwischen Bestäubung und Samenausbreitung unterscheiden und Bestäu-bung häufig als beabsichtigte Handlung der Insekten sehen. Außerdem zeigen die Vorstellungen über den Zusammenhang von Blüten und Besuchern, dass bereits zu Beginn der 5. Schulstufe Vorstellungen zu Anpassung und Angepasstheit vorhanden sind, die im Unterricht zur Evolution berücksichtigt werden müssen. Diese erhobenen Schülervorstellungen werden mit der fachlichen Perspektive in Beziehung gesetzt und daraus ableitbare fachdidaktische Implikationen diskutiert. ABSTRACT The process of pollination plays a major role in the lifecycle of plants and is important for understanding the variety of flowering plants. Pollination is also a current issue due to the colony collapse disorder of honeybees. Therefore, investigating students’ conceptions about pollination is highly relevant. The present study investigates conceptions of seven students from 5th grade using guided interviews with regard to pollination biology. Results show that students have serious difficulties differentiating between pollination and seed dispersal. Furthermore, there are differences between students’ conceptions and scientific con-ceptions as students often see pollination as a deliberate act of insects. Students’ conceptions about adaptations of flowers and their pollinators indicate that students’ from 5th grade use evolutionary conceptions which have to be considered when teaching evolution. Students’ conceptions will be discussed in relation to the scientific perspective to derive implications for teaching.

description: In May/June 2005, after 10 years of inactivity, the Be/X-ray binary system A 0535+26 underwent a major X-ray outburst. In this paper data are presented from 10 years of optical, IR and X-ray monitoring showing the behaviour of the system during the quiescent epoch and the lead up to the new outburst. The results show the system going through a period when the Be star in the system had a minimal circumstellar disk and then a dramatic disk recovery leading, presumably, to the latest flare up of X-ray emission. The data are interpreted in terms of the state of the disk and its interaction with the neutron star companion.

description: ZUSAMMENFASSUNG Um einen wirksamen schülerorientierten Unterricht zum Themenfeld Evolution, Schöpfung, Erdgeschichte und Entstehung der Welt gestalten zu können, ist es wichtig, vorhandene Schülervorstellungen zu kennen. Das Ziel der vorliegenden Studie ist eine quantitative Erhebung von Vorstellungen von 89 Viertklässlern zur Entstehung der Welt, des Lebens und des Menschen sowie zu Evolution und Schöpfung. Es wurde ein Fragebogen mit 16 Items konstruiert und getestet. Die Ergebnisse zeigen, dass die Schülervorstellungen zum genannten Themenfeld soziokulturell geprägt sind und sich in Abhängigkeit von der religiösen Sozialisation (d.h. der Religions- bzw. Konfessionszugehörigkeit) unterscheiden. Dabei ist es aber weder so, dass alle Kinder mit einer Zugehörigkeit zu einer Religionsgemeinschaft grundsätzlich einer gemeinsamen Abstammung kritisch gegenüberstehen, noch so, dass Kinder ohne Religionszugehörigkeit die Vorstellung eines Schöpfergottes (einer Schöpfung) pauschal ablehnen. Die in dieser Studie vorgestellten Erkenntnisse sind wichtig in Bezug auf die zu erwartenden Herausforderungen im naturwissenschaftlichen Sachunterricht. Dieser erfordert ein hohes Maß an Sensibilität im Hinblick auf die unterschiedlichen Vorstellungen sowie die weltanschauliche Vielfalt und muss gleichzeitig das Ziel verfolgen, fachlich belastbares Wissen zu vermitteln. ABSTRACT In order to design a student-orientated teaching in themes of evolution, creation, geological history and the origin of the world, existing students` conceptions must become transparent. The aim of the present study is the quantitative survey of conceptions of 89 fourth graders concerning the origin of the earth, of life and of man as well as evolution and creation. For this purpose, a questionnaire with 16 items was constructed and tested. The results show that the pupils’ conceptions on the mentioned topic are socio-cultural shaped and differ depending on religious socialization (i.e. religious affiliation). However, it is not the case that all children belonging to a religious community would fundamentally be critical of a common descent. Nor is it the case that children without religious affiliation would flatly reject the idea of a creator god (a creation). The findings presented in this study are important in relation to the expected challenges in science education and religious education. Such instruction requires a high degree of sensitivity with regard to the different ideas and the underlying worldviews. Nevertheless, the goal must be to provide the relevant scientific knowledge about the origin of the world and of life.

description: The characteristic function for heat fluctuations in a non equilibrium system is characterised by a large deviation function whose symmetry gives rise to a fluctuation theorem. In equilibrium the large deviation function vanishes and the heat fluctuations are bounded. Here we consider the characteristic function for heat fluctuations in equilibrium, constituting a sub-leading correction to the large deviation behaviour. Modelling the system by an oscillator coupled to an explicit multi-oscillator heat reservoir we evaluate the characteristic function.

description: We present an atmospheric characterization study of two medium sized planets bracketing the radius of Neptune: HD 106315 c (R$_{\rm{P}}$=4.98 $\pm$ 0.23 R$_{\oplus}$) and HD 3167 c (R$_{\rm{P}}$=2.740$_{-0.100}^{+0.106}$ R$_{\oplus}$). We analyse spatially scanned spectroscopic observations obtained with the G141 grism (1.125 - 1.650 $μ$m) of the Wide Field Camera 3 (WFC3) onboard the Hubble Space Telescope. We use the publicly available Iraclis pipeline and TauREx3 atmospheric retrieval code and we detect water vapor in the atmosphere of both planets with an abundance of $\log_{10}[\mathrm{H_2O}]=-2.1^{+0.7}_{-1.3}$ ($\sim$5.68$σ$) and $\log_{10}[\mathrm{H_2O}]=-4.1^{+0.9}_{-0.9}$ ($\sim$3.17$σ$) for HD 106315 c and HD 3167 c, respectively. The transmission spectrum of HD 106315 c shows also a possible evidence of ammonia absorption ($\log_{10}[\mathrm {NH_3}]=-4.3^{+0.7}_{-2.0}$, $\sim$1.97$σ$ -even if it is not significant-), whilst carbon dioxide absorption features may be present in the atmosphere of HD 3167 c in the $\sim$1.1-1.6~$μ$m wavelength range ($\log_{10}[\mathrm{CO_{2}}]= -2.4^{+0.7}_{-1.0}$, $\sim$3.28$σ$). However the CO$_2$ detection appears significant, it must be considered carefully and put into perspective. Indeed, CO$_2$ presence is not explained by 1D equilibrium chemistry models, and it could be due to possible systematics. The additional contribution of clouds, CO and CH$_4$ are discussed. HD 106315 c and HD 3167 c will be interesting targets for upcoming telescopes such as the James Webb Space Telescope (JWST) and the Atmospheric Remote-Sensing Infrared Exoplanet Large-Survey (Ariel).

description: We present a study of molecular outflows using six molecular lines (including 12CO/13CO/C18O/HCO+(J = 1-0) and SiO/CS(J = 2-1)) toward nine nearby high-mass star-forming regions with accurate known distances. This work is based on the high-sensitivity observations obtained with the 14-m millimeter telescope of Purple Mountain Observatory Delingha (PMODLH) observatory. The detection rate of outflows (including 12CO, 13CO, HCO+, and CS) is 100\%. However, the emission of SiO was not detected for all sources. The full line widths ($ΔV$) at 3$σ$ above the baseline of these molecular lines have the relationship $ΔV_{\rm ^{12}CO} > ΔV_{\rm HCO^{+}} > ΔV_{\rm CS} \approx ΔV_{\rm ^{13}CO} > ΔV_{\rm ^{18}CO}$. 12CO and HCO+ can be used to trace relatively high-velocity outflows, while 13CO and CS can be employed to trace relatively low-velocity outflows. The dynamical timescales of the 13CO and CS outflows are longer than those of the 12CO and HCO+ outflows. The mechanical luminosities, masses, mass-loss rates and forces of all outflows (including 12CO, 13CO, HCO+, and CS) are correlated with the bolometric luminosities of their central IRAS sources.

description: In the core accretion model, gas giant formation is a race between growth and migration; for a core to become a jovian planet, it must accrete its envelope before it spirals into the host star. We use a multizone numerical model to extend our previous investigation of the "window of opportunity" for gas giant formation within a disk. When the collision cross-section enhancement due to core atmospheres is taken into account, we find that a broad range of protoplanetary disks posses such a window.

description: Αυτοαντισώματα απέναντι σε συγκεκριμένα κυτταρικά αντιγόνα ανιχνεύονται συχνά στον ορό και εγκεφαλονωτιαίο υγρό ασθενών με νόσο Alzheimer και πιθανά παίζουν σημαντικό ρόλο στην εμφάνιση/εξέλιξη της νόσου. Στην παρούσα εργασία βρήκαμε ότι η πρωτεϊνική κινάση SRPK1 αποτελεί ένα καινούργιο αυτοαντιγόνο το οποίο είναι αυξημένο στους ασθενείς με νόσο Alzheimer. Χρησιμοποιώντας την μεθοδολογία της έμμεσης ELISA δείξαμε ότι υπάρχουν αυξημένα αντισώματα απέναντι στην SRPK1 – που στοχεύουν κύρια την πρώτη καταλυτική περιοχή της κινάσης – στον ορό ασθενών με Alzheimer, σε σχέση με τον ορό υγιών ηλικιωμένων. Παρόμοια αντισώματα βρέθηκαν και στο εγκεφαλονωτιαίο υγρό ασθενών, όπου όμως ο περιορισμένος αριθμός των δειγμάτων δεν μας επιτρέπει να εξάγουμε ένα σαφές συμπέρασμα αν η διαφορά στα επίπεδα των αυτοαντισωμάτων είναι στατιστικά σημαντική σε σχέση με τους υγιείς ηλικιωμένους. Τα αποτελέσματα αυτής της μελέτης δείχνουν για πρώτη φορά την ύπαρξη αυτοαντισωμάτων απέναντι στην SRPK1 σε ανθρώπινο ορό και είναι ενδεικτικά της ύπαρξης συσχέτισης ανάμεσα στα επίπεδα αυτών των αυτοαντισωμάτων και την εμφάνιση της νόσου Alzheimer.
description: Growing evidence suggests that autoantibodies targeting specific molecular antigens are present in sera and cerebrospinal fluids (CSFs) of patients with Alzheimer's disease (AD) and could play a role in the onset and/or progression of the disease. In this study we identified SR Protein Kinase 1 (SRPK1) as a new autoantigen elevated in AD. SRPK1, the prototype of the serine/arginine family of kinases, has been implicated in the regulation of multiple cellular processes such as pre-mRNA splicing, cell proliferation, chromatin structure, nuclear import and germ cell development. Using an ELISA assay, anti-SRPK1 autoantibodies were detected both in sera and CSF of patients with AD, at significantly elevated levels as compared to control subjects without dementia. The first catalytic domain was mapped as the main immunogenic region of the kinase. The findings of this study document for the first time the existence of autoantibodies targeting SRPK1 in human sera and are indicative of a correlation between the levels of a-SRPK1 autoantibodies and the incidence of AD.

description: We study the color-dependent confining forces between two quarks by the quenched lattice simulations of Coulomb gauge QCD. The color-singlet and color-antitriplet instantaneous potentials yield attractive forces. The ratio of the string tensions obtained from them is approximately 2 and have little volume dependence. Meanwhile, the color-octet and color-sextet channels give a minor contribution for two-quark system. We finally find that the infrared self-energy of the color-nonsinglet channels diverges in the infinite volume limit; however, the degree of the divergence on the finite lattice can be understood in terms of color factors.

description: It has been recently shown from observational data sets the variation of structural parameters and internal dynamical evolution of star clusters in the Milky Way and in the Large Magellanic Cloud (LMC), caused by the different gravitational field strengths that they experience. We report here some hints for such a differential tidal effects in structural parameters of star clusters in the Small Magellanic Cloud (SMC), which is nearly 10 times less massive than the LMC. A key contribution to this study is the consideration of the SMC as a triaxial spheroid, from which we estimate the deprojected distances to the SMC center of the statistically significant sample of star clusters analyzed. By adopting a 3D geometry of the SMC, we avoid the spurious effects caused by considering that a star cluster observed along the line-of-sight is close to the galaxy center. When inspecting the relationships between the star cluster sizes (represented by the 90% light radii), their eccentricities, masses and ages with the deprojected distances, we find: (i) the star cluster sizes are not visibly affected by tidal effects, because relatively small and large objects are spread through the SMC body. (ii) Star clusters with large eccentricities (> 0.4) are preferentially found located at deprojected distances smaller than $\sim$ 7-8 kpc, although many star clusters with smaller eccentricities are also found occupying a similar volume. (iii) Star clusters more massive than log(M /Mo) $\sim$ 4.0 are among the oldest star clusters, generally placed in the outermost SMC region and with a relative small level of flattening. These findings contrast with the more elongated, generally younger, less massive and innermost star clusters.

description: We analyze the steady viscoelastic fluid flow in slowly varying contracting channels of arbitrary shape and present a theory based on the lubrication approximation for calculating the flow rate-pressure drop relation at low and high Deborah ($De$) numbers. Unlike most prior theoretical studies leveraging the Oldroyd-B model, we describe the fluid viscoelasticity using a FENE-CR model and examine how the polymer chains' finite extensibility impacts the pressure drop. We employ the low-Deborah-number lubrication analysis to provide analytical expressions for the pressure drop up to $O(De^4)$. We further consider the ultra-dilute limit and exploit a one-way coupling between the parabolic velocity and elastic stresses to calculate the pressure drop of the FENE-CR fluid for arbitrary values of the Deborah number. Such an approach allows us to elucidate elastic stress contributions governing the pressure drop variations and the effect of finite extensibility for all $De$. We validate our theoretical predictions with two-dimensional numerical simulations and find excellent agreement. We show that, at low Deborah numbers, the pressure drop of the FENE-CR fluid monotonically decreases with $De$, similar to the previous results for the Oldroyd-B and FENE-P fluids. However, at high Deborah numbers, in contrast to a linear decrease for the Oldroyd-B fluid, the pressure drop of the FENE-CR fluid exhibits a non-monotonic variation due to finite extensibility, first decreasing and then increasing with $De$. Nevertheless, even at sufficiently high Deborah numbers, the pressure drop of the FENE-CR fluid in the ultra-dilute and lubrication limits is lower than the corresponding Newtonian pressure drop.

description: In the 1950's, Pomeranchuk predicted that, counterintuitively, liquid 3He may solidify upon heating, due to a high excess spin entropy in the solid phase. Here, using both local and global electronic entropy and compressibility measurements, we show that an analogous effect occurs in magic angle twisted bilayer graphene. Near a filling of one electron per moir'e unit cell, we observe a dramatic increase in the electronic entropy to about 1kB per unit cell. This large excess entropy is quenched by an in-plane magnetic field, pointing to its magnetic origin. A sharp drop in the compressibility as a function of the electron density, associated with a reset of the Fermi level back to the vicinity of the Dirac point, marks a clear boundary between two phases. We map this jump as a function of electron density, temperature, and magnetic field. This reveals a phase diagram that is consistent with a Pomeranchuk-like temperature- and field-driven transition from a low-entropy electronic liquid to a high-entropy correlated state with nearly-free magnetic moments. The correlated state features an unusual combination of seemingly contradictory properties, some associated with itinerant electrons, such as the absence of a thermodynamic gap, metallicity, and a Dirac-like compressibility, and others associated with localized moments, such as a large entropy and its disappearance with magnetic field. Moreover, the energy scales characterizing these two sets of properties are very different: whereas the compressibility jump onsets at T~30K, the bandwidth of magnetic excitations is ~3K or smaller. The hybrid nature of the new correlated state and the large separation of energy scales have key implications for the physics of correlated states in twisted bilayer graphene.

description: Die RÜTHERsche Moorkunde folgte dem klassischen Motto "Lernen mit Kopf, Herz und Hand". Auf den Spuren Rüthers wird eine kurze Einführung in den Lebensraum Moor gegeben. Der Darstellung ausgewählter ökologischer Fakten zu Mooren folgt die kritische Diskussion von zwei Standard-Schulversuchen zu Torfmoosen; die Versuche können gravierende Fehlvorstellungen zum Wasserhaushalt von Moorökosystemen provozieren ("Kopf"). Es wird ein neuer Schulversuch präsentiert, der zur Vermeidung solcher Fehlvorstellungen den klassischen Weg der Erkenntnisgewinnung über Hypothesenbildung und quasi-experimentelle Überprüfung ("Kopf" und "Hand") geht. Zu einer vollständigen biologiedidaktischen Moorkunde gehören auch ästhetische Aspekte ("Herz"). Anhand von Daten einer empirischen Untersuchung zur Bewertung von Moorökosystemen durch Schülerinnen und Schüler wird anschließend gezeigt, wie wichtig und aktuell die "Bildung des Herzens" in Zeiten der Bildung für Nachhaltige Entwicklung bleibt.

A cross-cultural comparison of women’s magazines in Japan and North America
Creators: name: Takayanagi, Nariko
Publisher: name: University of British Columbia
Year: 2009

description: Western feminists have viewed women's magazines as socializing agencies which shape women's perspectives of being female. It has been argued that the ideologically biased and limited content of women's magazines are obstacles for the achievement for gender equality and that more positive images of women are needed. Others argue that women's magazines serve to teach women how to be successful in male-oriented society. This thesis examines the visual and written messages regarding femininity found in women's magazines for young single working women in both Japan and North America. By using both quantitative and qualitative content analyses, the socio-cultural context of the role of women's magazines were compared. Results showed that women in both cultures are given limited positions in the world of women's magazines, although significant cultural differences were also observed. In advertisements, North American women's magazines tend to show both traditionally feminine (sexy and elegant) women and "new" and "active" women. The presence of predominantly macho-type male figures suggested the persisting subordination of women to men. Japanese women's images are narrowly defined, leaving only a few characteristics, such as pretty and cute, for women to choose. An examination of Caucasian female models in Japanese advertisements revealed that their presence could serve to establish Japanese cultural boundaries of femininity. Through the magazine's article content, North American women's magazines tend to have a variety of articles which encourage women to have it all or to become "superwomen." Japanese women's magazines clearly differentiated their content by the career orientedness of their targeted readership and most of the articles in the mainstream magazines are marriage-related. The overall findings suggest that North American women's magazines serve as "survival guides" for women to succeed in male-oriented society by learning both masculinity and femininity. In contrast, the main purpose of Japanese women's magazines apparently is to provide a cultural text for readers to gain femininity as a cultural resource to be successful as women in their society.

description: Gaia Early Data Release 3 (Gaia EDR3) gives trigonometric parallaxes for nearly 1.5 billion sources. Inspection of the EDR3 data for sources identified as quasars reveals that their parallaxes are biased, that is systematically offset from the expected distribution around zero, by a few tens of microarcsec. We attempt to map the main dependencies of the parallax bias in EDR3. In principle this could provide a recipe for correcting the EDR3 parallaxes. For faint sources the quasars provide the most direct way to estimate parallax bias. In order to extend this to brighter sources and a broader range of colours, we use differential methods based on physical pairs (binaries) and sources in the Large Magellanic Cloud. The functional forms of the dependencies are explored by mapping the systematic differences between EDR3 and DR2 parallaxes. The parallax bias is found to depend in a non-trivial way on (at least) the magnitude, colour, and ecliptic latitude of the source. Different dependencies apply to the five- and six-parameter solutions in EDR3. While it is not possible to derive a definitive recipe for the parallax correction, we give tentative expressions to be used at the researcher's discretion and point out some possible paths towards future improvements.
