description: In dieser Dissertation werden durch die Anwendung der Überlastpreisgestaltung leistungsfähigere verteilte Überlastabwehr-Algorithmen für TCP/IP-Netzwerke entwickelt. Die Theorie der Überlast­preisgestaltung basiert auf Wirtschaftstheorien und Optimierungsverfahren und führt zu einer optimalen Allokation von Netzwerkressourcen. Dabei werden im Mittel niedrige Warteschlangenlängen und gleichzeitig ein hoher Ausnutzungsgrad erzielt. Die Überlastabwehr-Algorithmen werden durch Anwendung von Regelungstechnik in Bezug auf Stabilität weiter untersucht.
description: This dissertation focuses on the design of more powerful distributed congestion control algorithms for TCP/IP networks by utilizing the theory of Congestion Pricing as a mathematical framework. Congestion Pricing, a strategy based on economics and optimization theory, leads to a social optimum for the entire network while Maintaining low queue sizes and, at the same time, high utilization. Using control theory, the stability of congestion control algorithms is further evaluated.

description: We present results for lattice QCD in the limit of infinite gauge coupling, obtained from a worm-type Monte Carlo algorithm on a discrete spatial lattice but with continuous Euclidean time. This is obtained by sending both the anisotropy parameter gamma^2 \sim a/a_t and the number of time-slices N_τto infinity, keeping the ratio γ^2/N_τ\sim aT fixed. The obvious gain is that no continuum extrapolation N_τ-> \infty has to be carried out. Moreover, the algorithm is faster and the sign problem disappears. We compare our computations with those on discrete lattices. We determine the phase diagram as a function of temperature and baryon chemical potential.

description: In this most-recent edition, the majority of Mesonet data is updated through 2006 with some additional information updated through 2007. The order of topical presentation found in both the first and second editions are preserved. In addition to climatological parameters updated, the current INL climatography includes new insights on winds and temperatures aloft derived from remote sensing systems, channeled wind flows, statistical wind trajectory groupings, and precipitation return periods. Data are presented in the context of three distinct local micro-climatic regimes (INL north-end, INL southwest, and INL southeast) that have emerged in recent assessments. It is anticipated that this most recent INL climatography will continue to be useful to planners and operations staff who support the most recent INL and ICP mission directives of revitalized nuclear reactor research and completion of the legacy cleanup.

description: Understanding the value that individuals assign to the protection of their personal data is of great importance for business, law, and public policy. We use a field experiment informed by behavioral economics and decision research to investigate individual privacy valuations and find evidence of endowment and order effects. Individuals assigned markedly different values to the privacy of their data depending on (1) whether they were asked to consider how much money they would accept to disclose otherwise private information or how much they would pay to protect otherwise public information and (2) the order in which they considered different offers for their data. The gap between such values is large compared with that observed in comparable studies of consumer goods. The results highlight the sensitivity of privacy valuations to contextual, nonnormative factors. © 2013 by The University of Chicago. All rights reserved.

Year: 2022

description: Social media has been an ever-growing medium with the expansion of multiple platforms and user adoption around the globe. According to Hootsuite’s Annual Digital Data Report for the year 2022, there are 4.62 billion users of social media across the globe, with a 10.1% increase from the subsequent year. This paper aims to explore Tiktok platform as a pedagogical tool for learning in the classroom for University Students in an "Online Behavior Class" at the American University in Cairo. Results show that Gen-Z University students indeed prefer integrating social media to their educational experience, and even prefer expressing through short video content over other assessment alternatives. Beyond that, short video content creation allowed them to express more creatively, and also reflecting on the class curriculum through using short video content production, was a more effective method of material reflection than other reflective methods.

description: In this work we study the effects of a longitudinal periodic potential on a parabolic quantum wire defined in a two-dimensional electron gas with Rashba spin-orbit interaction. For an infinite wire superlattice we find, by direct diagonalization, that the energy gaps are shifted away from the usual Bragg planes due to the Rashba spin-orbit interaction. Interestingly, our results show that the location of the band gaps in energy can be controlled via the strength of the Rashba spin-orbit interaction. We have also calculated the charge conductance through a periodic potential of a finite length via the non-equilibrium Green's function method combined with the Landauer formalism. We find dips in the conductance that correspond well to the energy gaps of the infinite wire superlattice. From the infinite wire energy dispersion, we derive an equation relating the location of the conductance dips as a function of the (gate controllable) Fermi energy to the Rashba spin-orbit coupling strength. We propose that the strength of the Rashba spin-orbit interaction can be extracted via a charge conductance measurement.

description: We report on theoretical and numerical study of propagation of atomic beams crossing a detuned standing-wave laser beam in the geometric optics limit. The interplay between external and internal atomic degrees of freedom is used to manipulate the atomic motion along the optical axis by light. By adjusting the atom-laser detuning, we demonstrate how to focus, split and scatter atomic beams in a real experiment. The novel effect of chaotic scattering of atoms at a regular near-resonant standing wave is found numerically and explained qualitatively. Some applications of the effects found are discussed.
The Cross-platform Social Engagement of Students
Creators: name: Johnson, Miriam J
Publisher: name: The Journal of Social Media for Learning
Year: 2022

description: With social media being a ubiquitous part of the way students engage with each other, this study explores how media, journalism, and publishing students use social media both in and outwith the classroom. It focuses on how cohorts use social media during class times – how they are speaking to each other and scrolling social feeds – and how they communicate about course related content after class. This research highlights the obligation that some students feel to answer questions that come into the group social channels, while linking that obligation to a sense of reciprocity. It shows how these issues are embedded it in the value exchange of emotional labour and its relationship to gender. Not all students feel obligated to take part and many indicate levels of frustration at the stream of questions, which can, in turn, exacerbate negative mental health issues in students.

Using Learning Management Systems to Scaffold Collaborative and Interactive Teaching and Learning

Year: 2022

description: The Sustainable Development Goal 4 of the United Nations advocates for inclusive and equitable quality education for all despite the unique circumstances faced by the learners and the teachers. Such circumstances could be economic, social or natural such as the COVID-19 Pandemic, which led to disruptions on the school calendar. Although several institutions of Higher Learning transited to online teaching using Learning Management Systems (LMS), the use of technology in ensuring interactivity and collaboration, which are crucial aspects of learning, needs to be examined more closely to establish its effectiveness. Given the fact that COVID -19 will be with us in the unforeseeable future, online teaching is here to stay. It is thus imperative to improve it so that the quality of education is not compromised. Previous research has shown the importance of Technology, Pedagogy and Content knowledge in effective delivery. LMS and related tools have been used to change the view of technology in the classroom, and the facilitator’s role is being re-evaluated. Successful facilitators look for innovative ways to scaffold the learning process. Instructional scaffolding is the process of supporting students in order to enhance learning and aid in the mastery of tasks. The aim of this study was to establish how LMS tools are used to improve collaboration and interaction in online teaching. The objectives were to establish which LMS tools are used to aid in interactivity and collaboration, how these tools are used to scaffold the teaching and learning process and how different elements interact to complete the scaffolding process. This study used a qualitative methodology where two virtual focus groups consisting of faculty and students in online graduate courses were used to review the scaffolding process. The findings were analyzed qualitatively and the results indicate that synchronous and asynchronous tools found in LMS and their plugins are used to scaffold collaboration and interaction. LMS tools were found to improve learning outcomes and to build a sense of community. The need for flexibility and the ability for LMS to be integrated with other tools and plugins was identified as crucial. The study established the need for both learners and faculty to be trained on the use of the tools was proposed as an additional requirement for the success of the scaffolding process.

description: The Novel Coronavirus (COVID-19) has infected over two hundred million worldwide and caused 4.4 million of deaths as of August 2021. Vaccines were quickly developed to address the pandemic. We sought to analyze the cost-effectiveness and budget impact of a non-specified vaccine for COVID-19. We constructed a Markov model of COVID-19 infections using a susceptible-exposed-infected-recovered structure over a 1-year time horizon from a U.S. healthcare sector perspective. The model consisted of two arms: do nothing and COVID-19 vaccine. Hospitalization and mortality rates were calibrated to U.S. COVID-19 reports as of November 2020. We performed economic calculations of costs in 2020 U.S. dollars and effectiveness in units of quality-adjusted life years (QALYs) to measure the budget impact and incremental cost-effectiveness at a $100,000/QALY threshold. Vaccines have a high probability of reducing healthcare costs and increasing QALYs compared to doing nothing. Simulations showed reductions in hospital days and mortality by more than 50%. Even though this represents a major U.S. investment, the budget impacts of these technologies could save program costs by up to 60% or more if uptake is high. The economic evaluation draws on the reported values of the clinical benefits of COVID-19 vaccines, although we do not currently have long-term conclusive data about COVID-19 vaccine efficacies. Spending on vaccines to mitigate COVID-19 infections offer high-value potential that society should consider. Unusually high uptake in vaccines in a short amount of time could result in unprecedented budget impacts to government and commercial payers. Governments should focus on expanding health system infrastructure and subsidizing payer coverage to deliver these vaccines efficiently.
La densità di una transizione. Successione, divinazione e infanticidio nel Ghana nord-orientale

description: The process of succession to the office of nakwe tu (village elder) opens up the understanding of a whole ensemble of ideas and practices among the Kassena people of West Africa. This article, based on fieldwork in the Upper East Region of Ghana, aims at exploring the thick meaning of this ritual transition, which is characterized by seemingly discordant principles. A prime example from the chiefdom of Paga is taken into account as a starting point in order to launch an ethnografical strategy that consists in following a series of meaningful connections found on the ground: from the specific tactics of people involved in the process to the final funeral rites, from recourses to divination to unstable definitions of reality, from the belief in dangerous, invisible dwarves to tragic accounts of ritual infanticides.

description: Several years of neutral particle measurements by the NASA/IBEX mission have yielded direct observations of interstellar neutral helium and oxygen. The data indicate the presence of secondary neutral helium and oxygen, which are created within the heliosphere by charge exchange involving helium or oxygen ions. This contribution describes a detailed conserving calculation method based on Keplerian orbits that has been developed to characterize helium distribution functions throughout the heliosphere, in particular in the innermost heliosphere, while accounting for loss and production of neutral particles along their path. Coupled with global heliosphere models of plasma distributions, this code is useful for predicting the fluxes of heavy neutral atoms at spacecraft detectors, so enabling inferences on the characteristics of the interstellar medium.

description: We study a mixture of ultracold spin-half fermionic and spin-one bosonic atoms in a shallow optical lattice where the bosons are coupled to the fermions via both density-density and spin-spin interactions. We consider the parameter regime where the bosons are in a superfluid ground state, integrate them out, and obtain an effective action for the fermions. We carry out a renormalization group analysis of this effective fermionic action at low temperatures, show that the presence of the spinor bosons may lead to a separation of Fermi surfaces of the spin-up and spin-down fermions, and investigate the parameter range where this phenomenon occurs. We also calculate the susceptibilities corresponding to the possible superfluid instabilities of the fermions and obtain their possible broken-symmetry ground states at low temperatures and weak interactions.

description: An extension of the scope of quantum theory is proposed in a way inspired by the recent heuristic as well as phenomenological success of the use of non-Hermitian Hamiltonians which are merely required self-adjoint in a Krein space with an indefinite metric (chosen, usually, as the operator of parity). In nuce, the parity-like operators are admitted to represent the mere indefinite metric in a Pontryagin space. A constructive version of such a generalized quantization strategy is outlined and, via a non-numerical illustrative example, found feasible.

Multi-photon absorption
neutron irradiation

description: This work presents the first experimental demonstration of the Three-Photon Absorption Transient Current Technique (3PA-TCT) in silicon carbide (SiC) detectors. By employing a femtosecond laser operating at 800 nm—corresponding to the fundamental wavelength of the laser system—localized charge generation is achieved through simultaneous absorption of three photons, enabling deep-substrate excitation without requiring frequency conversion. The experimental setup is significantly simplified compared to standard TPA-TCT, with moderate pulse energies and reduced surface photoabsorption (SPA) interference. A cubic dependence of the signal strength on laser intensity confirms the 3PA mechanism. Depth-resolved scans were performed on both non-irradiated and neutron-irradiated p-in-n SiC pad diodes, revealing clear signals and electric field dependence. The method demonstrated excellent spatial selectivity and robustness even after high-fluence irradiation (1×1015 neq/cm21 \times 10^{15}\,\text{n}_{\text{eq}}/\text{cm}^21×1015neq/cm2). These results open the door to compact, table-top 3PA-TCT systems using standard telecom and Ti:sapphire lasers, and represent a promising direction for wide bandgap semiconductor detector characterization.

0032 Labyrinth – fragments
Creators: name: Hussakowska-Szyszko, Maria
Publisher: name: RIHA Journal
Year: 2019

description: The installation by Robert Morris called Labyrinth, accompanying his monographic exhibition at the Museum of Art in Łódź, was one of his numerous works based on this theme. Besides the labyrinth itself, which belongs to forms most pregnant with meanings, at least two issues seem intriguing. The first is the dialogue of Minimalism with art of all eras, of which Morris is a brilliant exponent. The other issue is connected to the concept of site-specific art, developed by him in the 1960s and assuming a comprehensive analysis of a place, its history, its social, cultural and political environment, which justifies and anchors the work. The Łódź context forced the artist to change his strategy, but the work based on the (very rare in art history) pattern of a triangular labyrinth may be interpreted as an important element of Morris's Threading through a labyrinth. Tracing the changes in the Minimalist discourse of the recent decades I focus on a few interpretative lines, connected with the functioning of the "labyrinth" as a structure, I find some analogies between pattern repetitions by writers from the Oulipo group and the activities of Robert Morris.

description: Während im gymnasialen Segment eine steigende Internationalisierung festgestellt und Schule insgesamt zunehmend unter transnationalen Bedingungen thematisiert wird, wurden Internatsschulen in Deutschland bislang in Bezug auf ihren Umgang mit globalisierten und transnationalen Bedingungen und mit Internationalisierungsprozessen nicht untersucht. Anhand der vergleichenden Analyse von Schulleiterinterviews exklusiver staatlicher und privater Internatsschulen sowie unter Rückgriff auf ethnografische Beobachtungen sowie Selbstdarstellungen der Schulen wird im Beitrag untersucht, wie die Schulleiter Internationalität und Internationalisierung verstehen und sich in Bezug auf Prozesse der Internationalisierung und Transnationalisierung entwerfen und diese bearbeiten. Im Ergebnis lassen sich unterschiedliche Modi herausarbeiten, in denen Internationalität und Internationalisierung einen Teil der Legitimationspraxis und Superioritätsbehauptung der Schulen darstellen, als Schulentwicklungsaufgabe bearbeitet und als Rekrutierungsressource genutzt werden. Die Art der Trägerschaft ist jedoch eine zentrale Bedingung für die Ausgestaltung der Entwürfe und Praktiken der Internationalisierung und Transnationalisierung.

description: The structure and properties of (KxNa1-x)NbO3 lead-free piezoelectric ceramics was investigated in this work. Both the conventional mixed-oxide ceramics synthesis route and the high-throughput experimentation (HTE) approaches were employed for the synthesis. Structural characterization was carried out with synchrotron X-rays while the electrical properties were characterized with techniques (dielectric measurement, hysteresis measurements, impedance measurements etc). Both isovalent and aliovalent elements were used to dope(KxNa1-x)NbO3 ceramics in order to improve its piezoelectric properties and sinterability.
0040 Views of Peace and Prosperity – Hopes for Autonomy and Self-Government, Antwerp 1599
Creators: name: Cholcman, Tamar

description: In Flanders, the Entry of a new ruler into one of the cities of his domain (Joyeuse Entrée) transformed the urban landscape into a visual pamphlet – an opportunity to lay out the most urgent needs, hopes and demands of the people through a series of ephemeral monuments and civic ceremonies. The triumphal procession of the Archdukes Albert and Isabella into Antwerp in 1599, was likewise used by the city and by the creator of the pageant, humanist and city secretary Johannes Bochius, to lay out the main concerns and worries of their time. The article focuses on two of the monuments and the two ceremonies of oath taking in order to reveal the use of the pageant's structure as a 'progressing viewing experience'. The consideration of the viewing order reveals not only the strive for peace and the call to establish a self-governmental system under the rule of the new governors, but also the political thought of the time and the surprising demand to establish a mixed government, containing the fundaments of aristocracy and democracy within the monarchic rule of Spain.

The HST colours of high-redshift population III galaxies with strong Lyman alpha emission

description: Population III galaxies, made partly or exclusively of metal-free stars, are predicted to exist at high redshifts and may produce very strong Lya emission. A substantial fraction of these Lya photons are likely absorbed in the intergalactic medium at z>6, but recent simulations suggest that significant Lya emission may be detectable up to z~8.5, i.e. well into the reionization epoch. Here, we argue that high-redshift population III galaxies with strong Lya emission can be identified in Hubble Space Telescope imaging data because of their unusual colours. We quantify this effect in some of the filters used in Y-band dropout searches for galaxies at z~8 and find that population III galaxies with high Lya fluxes may exhibit much bluer J-H colours at z=8-10 than any normal type of galaxy at these redshifts. This colour signature can arise even if pop III stars account for as little as ~1e-3 to ~1e-2 of the stellar mass in these galaxies. Some of the anomalously blue objects reported in current Y-band dropout samples do in fact meet the colour criteria for Lya-emitting population III galaxies.

description: We present an extensive study of Mott insulator (MI) and superfluid (SF) shells in Bose-Hubbard (BH) models for bosons in optical lattices with harmonic traps. For this we develop an inhomogeneous mean-field theory. Our results for the BH model with one type of spinless bosons agrees quantitatively with quantum Monte Carlo (QMC) simulations. Our approach is numerically less intensive than such simulations, so we are able to perform calculation on experimentally realistic, large 3D systems, explore a wide range of parameter values, and make direct contact with a variety of experimental measurements. We also generalize our inhomogeneous mean-field theory to study BH models with harmonic traps and (a) two species of bosons or (b) spin-1 bosons. With two species of bosons we obtain rich phase diagrams with a variety of SF and MI phases and associated shells, when we include a quadratic confining potential. For the spin-1 BH model we show, in a representative case, that the system can display alternating shells of polar SF and MI phases; and we make interesting predictions for experiments in such systems.

Commentary on the European Court of Human Rights’ Judgment of 4 November 2014 in the case of Tarakhel v. Switzerland

description: Bei dem vorliegenden englischsprachigen Beitrag handelt es sich um eine Besprechung des am 4.11.2014 ergangenen Urteils des Europäischen Gerichtshofs für Menschenrechte (EGMR) im Fall Tarakhel v. Schweiz. Das Urteil ist hoch interessant und von großer Bedeutung für das gemeinsame europäische Asylsystem. Denn die große Kammer des Gerichts hat zu Gunsten der afghanischen Klägerfamilie überraschenderweise erstmals entschieden, dass eine Rücküberführung von Asylbewerbern nach Italien, insbesondere dann, wenn auch Minderjährige betroffen sind, gegen Artikel 3 EMRK verstößt, wenn der Entsendestaat zuvor keine individuellen Zusicherungen der italienischen Behörden darüber eingeholt hat, dass die Familie zusammen und in einer den nötigen Standards entsprechenden Einrichtung untergebracht und dem Alter der Kinder entsprechend versorgt werden wird. Damit senkt der EGMR, verglichen mit vorherigen Urteilen, die Schwelle des Artikel 3 EMRK und erhöht die Anforderungen, die an die Rechtmäßigkeit eines Transfers von Asylsuchenden im Rahmen des Dublin-Verfahrens zu stellen sind. The following article analyzes and comments on the European Court of Human Rights’ (ECtHR) judgment of 4 November 2014 in the case of Tarakhel v. Switzerland. This judgment is highly interesting and of special importance for the Common European Asylum System. The Court’s Grand Chamber surprisingly decided in favor of the Afghan applicant-family, holding for the first time that a transfer of asylum seekers to Italy, particularly if minors are concerned, violates Article 3 of the European Convention on Human Rights (ECHR) if the returning state has not obtained individual guarantees by the Italian authorities assuring that the family will be kept together in an institution which meets the required standards and provided with care appropriate to the age of any children involved. Thereby the Court lowers the threshold of Article 3 ECHR compared to earlier judgments and increases the requirements that have to be made on the legality of a transfer of asylum seekers under the Dublin procedure.

description: Yoram Alhassid conjectured that the total energy of a harmonically trapped two-component Fermi gas with large scattering length is a linear functional of the occupation probabilities of single-particle energy eigenstates. We confirm his conjecture and derive the functional explicitly. We show that the functional applies to ALL smooth potentials having a minimum, not just harmonic traps. We also calculate the occupation probabilities of high energy states.

title: Fiscal Spillovers: The Case of US Corporate and Personal Income Taxes

description: When the United States changes personal or corporate income tax rates, the economic effects are not just contained to that country. They spill over to other countries. However, the size and positive or negative effects of these spillovers are not clear.

We measure the impact of changes to personal and corporate income tax rates in the United States on its trading partners. We follow the methodology introduced by Mertens and Ravn (2013) to first identify unanticipated changes to US tax rates. We then estimate the spillover effects of these changes to Canada and other US trading partners.

We find that US corporate income tax cuts generally have negative cross-border spillover effects, though these effects are usually small. In Canada, these spillover effects turn positive over the long run. US personal income tax cuts generally have positive and sizable spillover effects that are most pronounced in emerging-market economies without fully flexible exchange rate regimes.
description: Quand les taux d’imposition sur le revenu des particuliers ou des entreprises changent aux États-Unis, les effets économiques qui s’en suivent se répercutent aussi sur d’autres pays. Cela dit, l’ampleur de ces répercussions transfrontières et leurs incidences positives ou négatives ne sont pas claires.

Nous mesurons les effets des changements de taux d’imposition des particuliers et des entreprises aux États-Unis sur les partenaires commerciaux de ce pays. Suivant la méthodologie de Mertens et Ravn (2013), nous recensons tout d’abord les changements imprévus ayant visé les taux d’imposition américains. Nous en estimons ensuite les répercussions sur le Canada et d’autres partenaires commerciaux des États-Unis.

Nous constatons que les baisses de taux d’imposition des entreprises américaines ont, en général, des répercussions transfrontières négatives, mais habituellement modérées. Au Canada, ces répercussions deviennent positives à long terme. Les baisses de taux d’imposition des particuliers américains, quant à elles, ont généralement des répercussions extérieures positives et assez importantes qui sont plus marquées dans les pays émergents dépourvus d’un régime de changes entièrement flottants.
