description: Several studies have identified a significant amount of redundancy in the network traffic. For example, it is demonstrated that there is a great amount of redundancy within the content of a server over time. This redundancy can be leveraged to reduce the network flow by the deployment of memory units in the network. The question that arises is whether or not the deployment of memory can result in a fundamental improvement in the performance of the network. In this paper, we answer this question affirmatively by first establishing the fundamental gains of memory-assisted source compression and then applying the technique to a network. Specifically, we investigate the gain of memory-assisted compression in random network graphs consisted of a single source and several randomly selected memory units. We find a threshold value for the number of memories deployed in a random graph and show that if the number of memories exceeds the threshold we observe network-wide reduction in the traffic.

description: The discovery of transiting planets around bright stars holds the potential to greatly enhance our understanding of planetary atmospheres. In this work we present the search for transits of HD 168443b, a massive planet orbiting the bright star HD 168443 V=6.92 with a period of 58.11 days. The high eccentricity of the planetary orbit e=0.53 significantly enhances the a-priori transit probability beyond that expected for a circular orbit, making HD 168443 a candidate for our ongoing Transit Ephemeris Refinement and Monitoring Survey (TERMS). Using additional radial velocities from Keck-HIRES, we refined the orbital parameters of this multi-planet system and derived a new transit ephemeris for HD 168443b. The reduced uncertainties in the transit window make a photometric transit search practicable. Photometric observations acquired during predicted transit windows were obtained on three nights. CTIO 1.0 m photometry acquired on 2010 September 7 had the required precision to detect a transit but fell just outside of our final transit window. Nightly photometry from the T8 0.8 m Automated Photometric Telescope (APT) at Fairborn Observatory, acquired over a span of 109 nights, demonstrates that HD 168443 is constant on a time scale of weeks. Higher-cadence photometry on 2011 April 28 and June 25 shows no evidence of a transit. We are able to rule out a non-grazing transit of HD 168443b.

description: We present SDO/AIA observations of the interaction of a global EUV wave on 2011 June 7 with active regions (ARs), coronal holes (CHs) and coronal bright structures. The primary global wave has a three-dimensional dome shape, with propagation speeds ranging from 430-780 km/s in different directions. The primary coronal wave runs in front of the expanding loops involved in the CME and its propagation speeds are approximately constant within 10-20 minutes. Upon arrival at an AR on its path, the primary EUV wave apparently disappears and a secondary wave rapidly reemerges 75 Mm within the AR boundary at a similar speed. When the EUV wave encounters a coronal bright structure, an additional wave front appears there and propagates in front of it at a velocity nearly a factor of 2 faster. Reflected waves from a polar CH and a coronal bright structure are observed and propagate fractionally slower than the primary waves. Some of these phenomena can be equally explained by either a wave or non-wave model alone. However, taken together, these observations provide new evidence for the multitudes of global EUV waves, in which a true MHD fast-mode wave or shock propagates in front of an expanding CME bubble.

description: This project aims to create spaces for children's emerging thoughts and ideas to be heard, fostered, and incorporated into their surrounding worlds. In working collaboratively with the children, the notion of sharing ideas is encouraged and through engaging in democratic conversations we worked with questions, such as, who can have ideas and where do ideas come from to explore the notion of the individual in a plural world. To cultivate a culture where children and educators are actively participating in reciprocal listening to each other's ideas. By embracing singularity and acknowledging the rights of the child, we can begin to work to unsilence the silenced.

description: The existence of primordial magnetic fields can induce matter perturbations with additional power at small scales as compared to the usual $Λ$CDM model. We study its implication within the context of two-point shear correlation function from gravitational lensing. We show that primordial magnetic field can leave its imprints on the shear correlation function at angular scales $\lesssim \hbox{a few arcmin}$. The results are compared with CFHTLS data, which yields some of the strongest known constraints on the parameters (strength and spectral index) of the primordial magnetic field. We also discuss the possibility of detecting sub-nano Gauss fields using future missions such as SNAP.

description: We discuss the relevance of directional detection experiments in the post-discovery era and propose a method to extract the local dark matter phase space distribution from directional data. The first feature of this method is a parameterization of the dark matter distribution function in terms of integrals of motion, which can be analytically extended to infer properties of the global distribution if certain equilibrium conditions hold. The second feature of our method is a decomposition of the distribution function in moments of a model independent basis, with minimal reliance on the ansatz for its functional form. We illustrate our method using the Via Lactea II N-body simulation as well as an analytical model for the dark matter halo. We conclude that O(1000) events are necessary to measure deviations from the Standard Halo Model and constrain or measure the presence of anisotropies.

Cosmochemical Consequences of Particle Trajectories During FU Orionis Outbursts by the Early Sun

description: The solar nebula is thought to have undergone a number of episodes of FU Orionis outbursts during its early evolution. We present here the first calculations of the trajectories of particles in a marginally gravitationally unstable solar nebula during an FU Orionis outburst, which show that 0.1 to 10 cm-sized particles traverse radial distances of 10 AU or more, inward and outward, in less than 200 yrs, exposing the particles to temperatures from $\sim$ 60 K to $\sim$ 1500 K. Such trajectories can thus account for the discovery of refractory particles in comets. Refractory particles should acquire Wark-Lovering-like rims as they leave the highest temperature regions of the disk, and these rims should have significant variations in their stable oxygen isotope ratios. Particles are likely to be heavily modified or destroyed if they pass within 1 AU of the Sun, and so are only likely to survive if they formed in the final few FU Orionis outbursts, or were transported to the outer reaches of the solar system. Calcium, aluminum-rich inclusions (CAIs) from primitive meteorites are the oldest known solar system objects and have a very narrow age range. Most CAIs may have formed at the end of the FU Orionis outbursts phase, with an age range reflecting the period between the last few outbursts.

description: The current state-of-the-art of population synthesis is reviewed. The field is currently undergoing major revisions with the recognition of several key processes as new critical ingredients. Stochastic effects can artificially enhance or suppress certain evolutionary phases and/or stellar mass regimes and introduce systematic biases in, e.g., the determination of the stellar initial mass function. Post-main-sequence evolution is often associated with irregular variations of stellar properties on ultra-short time-scales. Examples are asymptotic giant branch stars and luminous blue variables, both of which are poorly treated in the models. Stars rarely form in isolation, and the fraction of truly single stars may be very small. Therefore, stellar multiplicity must be accounted for since many systems will develop tidal interaction over the course of their evolution. Last but not least, stellar rotation can drastically increase stellar temperatures and luminosities, which in turn leads to revised mass-to-light ratios in population synthesis models.

description: We model and solve the problem of planning the loading and routing of an aircraft according to a utility score, weight and balance principles, fuel consumption, and cost increases due to centre of gravity displacement in a tour of simultaneous pickup and delivery. This is necessary because in the aerial pickup and delivery of goods, transport aviation faces risks of cargo unbalancing and wrong delivery due to the urgency required for loading for mission accomplishment. It is solved by integer programming and four known meta-heuristics to select the method that most fits the operational requirements. We also created a heuristic that quickly finds viable solutions for a wide range of problem sizes in much less than the operationally acceptable time. The output is an essential part of airlift because it guarantees flight safety, makes ground operations more efficient, and makes sure that each item gets to its right destination.

description: We have fabricated (Ba,K)Fe2As2 superconducting wires through ex-situ powder-in-tube method. Silver was used as a chemical addition to improve the performance of these superconducting wires. The transport critical current densities (Jc) have reached 1.3\times104 A/cm and 1.0\times104 A/cm2 at 4.2 K under self field in the wires with and without Ag addition. We used magneto-optical (MO) imaging technique to investigate the properties of grain boundaries in the (Ba,K)Fe2As2 superconducting wire with Ag addition. MO images show the weak links in the Fe-based superconducting wires for the first time. An intragranular Jc of 6.0\times104 A/cm2 at 20 K is obtained from MO image, which is consistent with the estimation from M-H measurement.

Challenges of International Students in Filing Taxes and Using Tax Services in Canada

description: Starting new lives in an unfamiliar environment, international students may encounter difficulties in dealing with their tax reports. They are often faced with challenges about the ways in which tax works. In this thesis, three main tax filing challenges of international students are defined: identity and tax, tax complexity and tax knowledge. As previous tax literature has not sufficiently explored the tax experiences of international students, there is a need for research that addresses the lived tax experiences of this minority group. Therefore, this thesis aims to explore the phenomenon of international students’ tax filings. Providing an interpretive exploration of international students’ tax-related challenges, the researcher interviewed 20 international students to explore what challenges they are experiencing and how they are experiencing the challenges. To deepen the understanding of tax filing challenges, the researcher uses functional attitude theory (FAT) to analyze international students’ lived experiences and employs a phenomenological approach to gain profound insights into international students’ tax filings. Looking into international students’ functional attitudes towards the tax flings reveals the impacts that the challenges have on their perspectives of tax filings. The findings show that international students make tax decisions in relation to their utilitarian attitudes, willingness of social adjustment, different values and knowledge about tax. Particularly, this thesis contributes to the understanding regarding the international students’ tax filing challenges in Canada.

description: The young X-ray and gamma-ray-bright supernova remnant RXJ1713.7-3946 (SNR G347.3-0.5) is believed to be associated with molecular cores that lie within regions of the most intense TeV emission. Using the Mopra telescope, four of the densest cores were observed using high-critical density tracers such as CS(J=1-0,J=2-1) and its isotopologue counterparts, NH3(1,1) and (2,2) inversion transitions and N2H+(J=1-0) emission, confirming the presence of dense gas >10^4cm^-3 in the region. The mass estimates for Core C range from 40M_{\odot} (from CS(J=1-0)) to 80M_{\odot} (from NH3 and N2H+), an order of magnitude smaller than published mass estimates from CO(J=1-0) observations. We also modelled the energy-dependent diffusion of cosmic-ray protons accelerated by RXJ1713.7-3946 into Core C, approximating the core with average density and magnetic field values. We find that for considerably suppressed diffusion coefficients (factors χ=10^{-3} down to 10^{-5} the galactic average), low energy cosmic-rays can be prevented from entering the inner core region. Such an effect could lead to characteristic spectral behaviour in the GeV to TeV gamma-ray and multi-keV X-ray fluxes across the core. These features may be measurable with future gamma-ray and multi-keV telescopes offering arcminute or better angular resolution, and can be a novel way to understand the level of cosmic-ray acceleration in RXJ1713.7-3946 and the transport properties of cosmic-rays in the dense molecular cores.

description: The discovery of cosmic acceleration is one of the most important developments in modern cosmology. The observation, thirteen years ago, that type Ia supernovae appear dimmer that they would have been in a decelerating universe followed by a series of independent observations involving galaxies and cluster of galaxies as well as the cosmic microwave background, all point in the same direction: we seem to be living in a flat universe whose expansion is currently undergoing an acceleration phase. In this paper, we review the various observational evidences, most of them gathered in the last decade, and the improvements expected from projects currently collecting data or in preparation.

description: One of the crucial 21st-century digital skills, in the context of digital transformation, is problem solving—equally so in the fields of science, technology, engineering, and mathematics (STEM). In the context of kindergarten, learning through play is central; therefore, pretend play, and particularly guided pretend play, is suggested as an innovative way to foster skills for digital problem solving. As yet, the potential of pretend play for children’s learning about digital transformation and digital problem-solving processes has hardly been researched. The paper examines how children solve digital problems in guided pretend play. In an explorative intervention study “We play the future”, an information technology center (IT center) is introduced as one of the play corners for pretend play in kindergartens, together with other inputs such as a smart home corner (Internet of Things) or autonomous vehicles. Children’s play was video recorded. From the 15 participating kindergartens, 13 h of sequences involving the IT center were analyzed using content analysis. The findings indicate that children identify problems in a play situation and solve them using problem-solving strategies, such as devising new applications and installing software. Furthermore, the findings show that the kindergarten teacher’s participation in the pretend play is important for enabling longer and more complex problem-solving processes. Consequences for further teacher training to foster problem-solving skills during guided pretend play are discussed.

description: An adiabatic method for a single-shot non-demolition measurement of the phase qubit is suggested. The qubit is inductively coupled to a low-frequency resonator, which in turn is connected with a classical measurement device (phase meter). The resonator drives adiabatic oscillations of the supercurrent in the qubit loop. The back reaction of the qubit loop on the resonator depends on the qubit state. Measuring the phase shift of the resonator's oscillations one can determine the state of the qubit. Numerical computations with available experimental parameters show that the phase difference between the two qubit states increases at a rate of 0.0044 rad/ns with the fidelity of about 0.9989 and the measurement time of about 100 ns. The fidelity of the measurement is estimated taking into consideration possible quantum transitions inside and outside the qubit manifold. An increase of the phase difference is possible but it is linked to a reduction of the fidelity. The requirements for the reproducibility of the qubit and resonator parameters are formulated.

VLBA SiO maser observations of the OH/IR star OH 44.8-2.3: magnetic field and morphology

description: SiO maser emission occurs in the extended atmosphere of evolved stars and can be studied at high angular resolution. Very long baseline interferometry (VLBI) observations of Mira variables indicate that SiO masers are significantly linearly polarized with linear polarization fraction up to 100%. However, no information is available at high angular resolution for SiO masers in higher mass loss OH/IR stars. We extend the VLBI SiO maser studies to OH/IR stars. The observations enable us to understand the SiO pumping mechanisms in higher mass loss evolved objects and compare those with Mira variables. Additionally, polarimetric observations of SiO masers help us to understand the magnetic field strength and morphology and to distinguish between conflicting polarization theories. The 43 GHz SiO maser observations of the OH/IR star OH 44.8-2.3 were performed with the VLBA in full polarization spectral line mode. Auxiliary EVLA observations were performed to allow for the absolute calibration of the polarization angle. The Zeeman splitting was measured by cross correlating the right and left circular polarization spectra as well as the S-curve fitting. Additionally, we analyzed the 1612 MHz OH maser observations of OH 44.8-2.3 from the VLA archive. The SiO masers of OH 44.8-2.2 form a ring located at ~5.4 AU around the star. The masers appear to be highly linearly polarized with fractional linear polarization up to 100%. The linear polarization vectors are consistent with a dipole field morphology in this star. We report a tentative detection of circular polarization of ~0.7% for the brightest maser feature. The magnetic field measured for this feature corresponds to 1.5\pm0.3 G. Additionally, the distribution of the 1612 MHz OH maser emission could indicate an elongated morphology.

Die Qualität der makro-adaptiven (mathematischen) Lernunterstützung (Planung und Reflexion von Lernsituationen) wurde im Kindergarten bis jetzt noch nicht umfassend untersucht. Sie gewinnt jedoch im Hinblick auf die zunehmende Bedeutung von Bildungsplänen im Kindergarten und der damit verbundenen Förderung von fachbezogenen Kompetenzen an Bedeutung. Im Artikel wird erstens die Qualität von (mathematischer) Lernunterstützung in Regelspielsituationen im Kindergarten konzeptualisiert. Dabei wird die Qualität der makro-adaptiven von der mikro-adaptiven Lernunterstützung unterschieden. Letztere wird getrennt in fachunabhängige Unterstützungsqualität (Gruppenmanagement, emotionale Wärme) und in instruktionale, mathematikbezogene Unterstützungsqualität (Lernanregung, Verwendung Fachsprache). Zweitens wird ein Messinstrument (Rating) zur Analyse der Qualität der Lernunterstützung in mathematischen Lernsituationen vorgestellt. Dieses wurde zur Analyse von videografierten Regelspielsituationen und anschließenden Leitfadeninterviews von 145 pädagogischen Fachkräften aus Deutschland und der Schweiz eingesetzt. Pro Fachkraft standen zwei Videosequenzen und zwei Interviews zur Verfügung. Auf der Basis dieser Daten wird das Messinstrument hinsichtlich verschiedener Gütekriterien sowie des Einflusses der Ausbildung der Fachkräfte (akademisch, nicht akademisch) und des Bildungskontextes (Deutschland, Schweiz) analysiert. Die theoretisch angenommene Unterscheidung von Gruppenmanagement, emotionaler Wärme und instruktionaler Unterstützungsqualität lässt sich durch eine konfirmatorische Faktorenanalyse stützen. Die Ergebnisse bestätigen die Bedeutung des Einbezugs von Planung und Reflexion als Dimensionen von adaptiver Lernunterstützungsqualität.

description: Context. We carry out a detailed 2D study of the ionised gas in the local universe galaxy UGC9837. In nearby galaxies, like the galaxy in question here, the spatial distribution of the physical properties can be studied in detail, providing benchmarks for galaxy formation models. Aims. Our aim is to derive detailed and spatially resolved physical properties of the ionised gas of UGC 9837. In addition, we derive an integrated spectrum of the galaxy and study how varying spatial coverage affects the derived integrated properties. We also study how the same properties would be seen if the galaxy was placed at a higher redshift and observed as part of one of the high-z surveys. Methods. UGC9837 was observed using the PMAS PPAK integral field unit. The spectra are reduced and calibrated and the stellar and ionised components separated. Using strong emission line ratios of the ionised gas, the source of ionisation, the dust extinction, the star formation rate, the electron density and the oxygen abundance derived from a total integrated spectrum, central integrated spectrum and individual fibre spectra are studied. Finally, the same properties are studied in a spectrum whose spatial resolution is degraded to simulate high-z observations. Results. The spatial distribution of the ionised gas properties is consistent with inside-out growing scenario of galaxies. We also find that lack of spatial coverage would bias the results derived from the integrated spectrum leading, e.g., to an under-estimation of ionisation and over-estimation of metallicity, if only the centre of the galaxy was covered by the spectrum. Our simulation of high-z observations shows that part of the spatial information, such as dust and SFR distribution would be lost while shallower gradients in metallicity and ionisation strength would be detected.

description: The innovation project ProSpra differs from introductions to academic writing by working on a text from one's own field of study: students first write a text on a typical assignment from their field of study, which is then revised step by step. Writing assignments from two fields of study are used as examples: business studies and teacher training programmes. Other fields of study will follow, but students of other subjects can already benefit from how to connect independent thoughts with existing scientific findings in a systematic and methodologically controlled way. The project focused on the following questions: What educational language skills do students need at the beginning of their studies to deal with writing tasks they typically encounter in their field of study?
Scattering of circularly polarized light by a rotating black hole

Year: 2012
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We study scattering of polarized light by a rotating (Kerr) black hole of the mass M and the angular momentum J. In order to keep trace of the polarization dependence of photon trajectories one can use the following dimensionless parameter: $\varepsilon=\pm (ωM)^{-1}$, where $ω$ is the photon frequency and the sign + (-) corresponds to the right (left) circular polarization. We assume that $|\varepsilonl << 1$ and use the modified geometric optics approximation developed in [1], that is we include the first order in $\varepsilon$ polarization dependent terms into the eikonal equation. These corrections modify late time behavior of photons. We demonstrate that the photon moves along a null curve, which in the limit $\varepsilon=0$ becomes a null geodesic. We focus on the scattering problem for polarized light. Namely, we consider the following problems: (i) How does the photon bending angle depend on its polarization; (ii) How does position of the image of a point-like source depend on its polarization; (iii) How does the arrival time of photons depend on their polarization. We perform the numerical calculations that illustrate these effects for an extremely rotating black hole and discuss their possible applications.

description: I construct exact solutions for general nonextremal rotating, charged Kaluza-Klein black holes with a cosmological constant and with arbitrary angular momenta in all higher dimensions. I then investigate their thermodynamics and find their generalizations with the NUT charges. The metrics are given in both Boyer-Lindquist coordinates and a form very similar to the famous Kerr-Schild ansatz, which highlights its potential application to include multiple electric charges into solutions yet to be found in gauged supergravity. It is also observed that the metric ansatz in $D = 4$ dimensions is similar to those previously suggested by Yilmaz and later by Bekenstein.

description: We report on the growth and electrical characterization of a series of two-dimensional hole systems (2DHSs) used to study the density dependence of low temperature mobility in 20 nm GaAs/AlGaAs quantum wells. The hole density was controlled by changing the Al mole fraction and the setback of the delta-doping layer. We varied the density over a range from 1.8 $\times$ 10$^{10}$ cm$^{-2}$ to 1.9 $\times$ 10$^{11}$ cm$^{-2}$ finding a nonmonotonic dependence of mobility on density at T = 0.3 K. Surprisingly, a peak mobility of 2.3 $\times$ 10$^6$ cm$^2$/Vs was measured at a density of 6.5 $\times$ 10$^{10}$ cm$^{-2}$ with further increase in density resulting in reduced mobility. We discuss possible mechanisms leading to the observed non-monotonic density dependence of the mobility. Relying solely on interface roughness scattering to explain the observed drop in mobility at high density requires roughness parameters which are not consistent with measurements of similar electron structures. This leaves open the possibility of contributions from other scattering mechanisms at high density.

title: Banking on Trust
title: Historical Perspectives on Changes and Continuities in the Strategies of Rebuilding Corporate Legitimacy in British Joint-Stock Banks, c. 1830s-60s

Creators: name: Chan, Alvin

Subjects: Victorian Britain; joint-stock banks; banking crisis; trust repair; stakeholders

description: This thesis uses the organisational trust repair model developed by
 Gillespie and Dietz to examine how effectively selected joint-stock banks
 from Northwest England rebuilt corporate legitimacy amidst periodic
 commercial crises in the nineteenth century. Given organisational
 complexity and exposure to shifting market sentiments, this thesis focuses
 on how bank directors simultaneously managed trust and distrust in a
 hostile environment, in which different parties were prone to distrust
 just as much as they were to trust. By exploring various approaches to
 repairing organisational trust across different banking institutions, this
 thesis argues that successful trust repair requires one to understand how
 trust was damaged in the first place, because different violations require
 distinct reparative responses as conditioned by varying circumstances.

 Following the belief that organisational legitimacy is a generalised
 perception among stakeholders that corporate actions are aligned with
 social norms and values, the research applies a cultural narrative
 approach to demonstrate how the interplay of socio-cultural factors drove
 the dynamics of trust repair. For this purpose, it uses different cultural
 sources, official papers, and archival materials to reconstruct the
 nineteenth-century contexts in which banking companies sought to repair
 trust. This thesis also argues that the dynamics of trust repair were
 essentially compounded by four key features of banking, namely: (1)
 information and power asymmetry between management and stakeholders; (2)
 competing expectations from different stakeholder groups; (3) the delicate
 balance between returns and risks from financial investment, and (4) the
 interconnectedness of banking institutions and the real economy. Through
 the combination of a contemporary theoretical framework with the
 historical contexts, the thesis aims to present the case for (1)
 understanding the past through the perspectives of management scholars in
 the twenty-first century, and (2) assessing the applicability of modern
 trust repair strategies in relation to historical patterns and practices.
