description: This single-site case study aims to evaluate the effectiveness of the learning activities in a flipped EFL class so that critical pedagogical insights can be generated to enhance the design and implementation of flipped classrooms. Student engagement in learning activities was explored and examined to understand how the flipped classroom (FC) activities enhanced learning. A convergent parallel mixed-methods design with nested samples was adopted to collect data over a 15-week semester. Participants were from a flipped EFL class (n = 25) and a blended EFL class (n = 28). Data were collected from focus group discussions, participant observation, the learning management system (LMS) and iWrite. An adapted four-level Kirkpatrick Model was employed as the evaluation framework to explore student engagement in the learning activities and measure the learning outcomes. Kahu’s engagement framework was employed to discuss the influencing factors. The findings of this project showed that the flipped design enhanced student performance in the learning process though there was no statistically significant difference in student final examination grades between the two classes. The findings further indicated that student engagement in learning activities was influenced by the interplay of teaching practices and student characteristics. Meanwhile, it was mediated by the assessment policy and practice and shaped by significant socio-cultural influences of China’s educational system and social conventions. Evidence-based reflections were then made to improve the design, implementation and evaluation of flipped classrooms. This project fills the current knowledge gap in the learning process of the flipping pedagogy and furthers our understanding of the mechanisms contributing to student engagement in flipped learning.

description: An effective model with pions and constituent quarks in the presence of a weak external background electromagnetic field is derived by starting from a dressed one gluon exchange quark-quark interaction.By applying the auxiliary field and background field methods, the structureless pion limit is considered to extract effective pion and constituent quark couplings in the presence of a weak magnetic field. The leading terms of a large quark and gluon masses expansion are obtained by resolving effective coupling constants which turn out to depend on a weak magnetic field. Two pion field definitions are considered for that. Several relations between the effective coupling constants and parameters can be derived exactly or in the limit of very large quark mass at zero and weak constant magnetic field. Among these ratios, the Gell Mann Oakes Renner and the quark level Goldberger Treiman relations are obtained. In addition to that, in the pion sector, the leading terms of Chiral Perturbation Theory coupled to the electromagnetic field is recovered. Some numerical estimates are provided for the effective coupling constants and parameters.

Interethnische Konflikterfahrungen in Ungarn nach 1945
Creators: name: Márkus, Beáta
Publisher: name: Zeitschrift für Migrationsforschung
Year: 2023

description: Von Ende 1945 bis 1949 wurden etwa 200.000 Angehörige der deutschsprachigen Minderheit Ungarns nach Deutschland vertrieben. Der Rest der »Deutschen« durfte, entrechtet und enteignet, im nun sozialistischen Land bleiben. Zeitgleich kamen Tausende ungarischsprachige Flüchtlinge und Vertriebene aufgrund von Grenzverschiebungen und im Rahmen des ungarisch-tschechoslowakischen »Bevölkerungsaustausches« nach Ungarn, wo sie sich in den ehemaligen deutschen Siedlungsgebieten niederlassen durften. Die Konsequenzen waren eine Auflösung traditioneller Minderheitengebiete und die Entstehung neuer Formen der interethnischen Interaktion. Der Beitrag setzt sich mit dieser konfliktbelasteten Periode im Spiegel der Fachliteratur und lokaler weltlicher und kirchlicher Quellen auseinander. Der Schwerpunkt der Analyse liegt auf der Phase der Migrationen und der durch sie hervorgerufenen Spannungen. Im Ausblick wird danach gefragt, ob und inwieweit die Konflikterfahrungen tradiert wurden und inwiefern sie bis heute in den Dorfgemeinschaften präsent sind. Interethnic Conflict Experiences in Hungary after 1945 From late 1945 to 1949, around 200,000 members of Hungary's German minority were expelled to Germany. The rest of the »Volksgruppe« was allowed to remain disenfranchised and dispossessed in the socialist state. Also in 1945, thousands of Hungarian refugees fled into Hungary because of the border modifications and the Hungarian-Czechoslovak population exchange, where they were settled in the previously German regions. As a result, traditional minority settlements were eliminated and new forms of inter-ethnic interaction emerged. This paper takes a close look at this conflict-ridden period on the basis of local sources. The focus of the analysis is on the time of the migrations and the tensions caused by them. The outlook asks whether and to what extent the conflict experiences have been passed on and are still present in the local communities today.

description: Der Beitrag analysiert die Konstruktion von Fremdheit in Barcelona während der Zwischenkriegszeit. Wie sich diese konkret manifestierte, wird zum einen an der Entwicklung der Stadtgeografie Barcelonas und zum anderen anhand ausgewählter Zeitungsartikel und Reportagen vor allem hinsichtlich der Frage untersucht, wie sich ethnische Fremdzuschreibungen und die Konstruktion von Fremdheit auf das Zusammenleben in der Stadt auswirkten. Dadurch arbeitet der Beitrag beispielhaft heraus, wie der Katalanismus durch die im Zuge der Arbeitsmigration entstehenden Auseinandersetzungen (re)aktiviert wurde und wie sich soziale und politische Konflikte auf die (inter)ethnischen Verhältnisse in Barcelona auswirkten. »Gypsies«, »Apaches« and »Murcianos«. Catalanism and Constructions of Otherness in Local Discourses and in Barcelona’s Urban Geography before Spanish Civil War This contribution analyzes the construction of ›otherness‹ in Barcelona before the Civil War. On the one hand, it focuses on the evolution of Barcelona’s urban geography and on the other hand, selected articles and reports in local newspapers are examined asking how foreignness in contrast to a local, ur-ban identity is constituted. Furthermore, this contribution elaborates on the question how Catalanism was (re)activated in the struggles caused by labor migration and how the social and political conflicts affected the (inter)eth-nical interactions in Barcelona.

Durch Migration ›estnisch‹ werden: Ethnizität als Ressource in den Lebenserzählungen von 1941 aus Estland nach Deutschland Umgesiedelten
Creators: name: Tark, Triin
Publisher: name: Zeitschrift für Migrationsforschung
Year: 2022

description: Dieser Artikel befasst sich mit dem Konzept Ethnizität als Ressource, die in von Migration geprägten Situationen aktiviert werden kann, um bestimmte Ziele zu erreichen. Analysiert werden die Lebenserzählungen von vier Menschen, die im Jahr 1941 aus Estland nach Deutschland umgesiedelt wurden und die nach dem Ende des Zweiten Weltkriegs einen Flüchtlingsstatus erhielten. Der Artikel basiert auf Lebenserzählungen und Archivquellen und untersucht, wie Ethnizität in den Lebenserzählungen als eine Ressource thematisiert wird, auf die im Laufe des Lebens zurückgegriffen worden ist. Während die Befragten ihre Umsiedlung als ›Deutsche‹ eher als Fälschung oder Manipulierung von Dokumenten darstellen, beschreiben sie das Erlangen des Status als ›Displaced Persons‹ aufgrund ihrer Einordnung als ›Est*innen‹ als etwas Selbstverständliches. Angesichts des mehrdimensionalen kulturellen und sprachlichen Hintergrunds der Befragten zeigt dieses Ergebnis, wie entscheidend sich eine solche Unterscheidung für ihr postmigrantisches Leben und bezüglich des Forschungsverfahrens erweisen kann. Die Ergebnisse hängen von den Lebenserfahrungen der Befragten einerseits und den Zielen des Forschungsprojekts, den Beziehungen zwischen Forscher*innen und Befragten wie auch von den leitenden Fragen während der Interviews andererseits ab. Becoming ›Estonian‹ through Migration: Ethnicity as a Resource in the Narratives of People Resettled from Estonia to Germany in 1941 This article deals with the concept of ethnicity as a resource that can be activated in situations characterised by migration in order to achieve certain goals. It analyses the narratives of four people who were resettled from Estonia to Germany in 1941 and acquired a DP status after the end of the World War II. Based on life narratives and archival sources, the article explores how ethnicity is thematised in the life narratives as resource that has been drawn upon throughout life. While the respondents tend to present their resettlement as ›Germans‹ as a falsification or manipulation of documents, they describe acquiring a DP status as something taken for granted because of their classification as ›Estonians‹. Given the multidimensional cultural and linguistic background of the respondents, this result demonstrates how decisive such a distinction can prove to be for their post‐migrant lives and regarding the research process. The findings depend on the life experiences of the respondents, on the one hand, and the goals of the research project, the relationships between researchers and interviewees as well as the guiding questions during interviews, on the other hand.

description: We formulate a conjecture for the second generation characters of indecomposable tilting modules for ${\rm SL}_3$.

Our conjecture can be interpreted as saying that these characters are governed by a discrete dynamical system ("billiards bouncing in alcoves"). The conjecture implies that decomposition numbers for symmetric groups display (at least) exponential growth.

Reputation und Ausweis. Die Feststellung nationaler Zugehörigkeit in Hispanoamerika
Creators: name: Biersack, Martin
Publisher: name: Zeitschrift für Migrationsforschung
Year: 2022

description: ›Ausländer‹ ist keine Wesensbestimmung, sondern eine relationale Kategorie. Eine Person wird in einem bestimmten Zusammenhang als Ausländer bezeichnet, um ihre Nichtzugehörigkeit zu verdeutlichen. Die Zuordnung zur Kategorie des Ausländers (extranjero) war im kolonialen Hispanoamerika von besonderer Bedeutung, denn hier verboten die Gesetze den extranjeros den Aufenthalt. Dennoch lebten viele Migranten nichtspanischer Herkunft in Hispanoamerika. Aus der Spannung zwischen der de facto Duldung und der Exklusion de jure resultierten zahlreiche Konflikte um Personen, deren Aufenthalt als Ausländer in Frage gestellt wurde. Für die kolonialen Behörden war es alles andere als einfach zu bestimmen, wer als extranjero und wer als Spanier zu gelten hatte. In diesem Beitrag werden sowohl die Praktiken der kolonialen Verwaltung zur Identifikation von Personen analysiert als auch die Strategien nichtspanischer Migranten, sich einer für sie nachteiligen Kategorisierung als extranjero zu entziehen. Ausgangspunkt ist dabei die Frage, in welchen Situationen die Kategorie des extranjero überhaupt aktiviert und die nationale Zugehörigkeit einer Person relevant wurde. Reputation and Credentials. Determining National Belonging in Hispano‐America ›Foreigner‹ is a relational, not an essentialist category. In any specific context, a person is categorized as a foreigner to indicate their nonbelonging. The category of foreigner (extranjero) was of particular importance in colonial Hispano‐America because the laws prohibited extranjeros from residing there. Nevertheless, there were many migrants of non‐Hispanic origin living in Hispano‐America. Tension between the de facto tolerance and the de jure exclusion resulted in numerous conflicts around those people whose residence as foreigners was questioned. However, it was difficult for the colonial authorities to determine who should be treated as a foreigner and who as a Spaniard. This article analyses both the practices of the colonial administration when identifying people’s national belonging and the strategies of the non‐Spanish migrants in avoiding being discriminated against and categorized as extranjero. For this, the starting point is to determine those situations in which the category extranjero was activated so that a personʹs national belonging became relevant.

description: Since Alan Turing envisioned Artificial Intelligence (AI) [1], a major driving force behind technical progress has been competition with human cognition. Historical milestones have been frequently associated with computers matching or outperforming humans in difficult cognitive tasks (e.g. face recognition [2], personality classification [3], driving cars [4], or playing video games [5]), or defeating humans in strategic zero-sum encounters (e.g. Chess [6], Checkers [7], Jeopardy! [8], Poker [9], or Go [10]). In contrast, less attention has been given to developing autonomous machines that establish mutually cooperative relationships with people who may not share the machine's preferences. A main challenge has been that human cooperation does not require sheer computational power, but rather relies on intuition [11], cultural norms [12], emotions and signals [13, 14, 15, 16], and pre-evolved dispositions toward cooperation [17], common-sense mechanisms that are difficult to encode in machines for arbitrary contexts. Here, we combine a state-of-the-art machine-learning algorithm with novel mechanisms for generating and acting on signals to produce a new learning algorithm that cooperates with people and other machines at levels that rival human cooperation in a variety of two-player repeated stochastic games. This is the first general-purpose algorithm that is capable, given a description of a previously unseen game environment, of learning to cooperate with people within short timescales in scenarios previously unanticipated by algorithm designers. This is achieved without complex opponent modeling or higher-order theories of mind, thus showing that flexible, fast, and general human-machine cooperation is computationally achievable using a non-trivial, but ultimately simple, set of algorithmic mechanisms.

description: I present a semiclassical analysis of a spatial-mode demultiplexing (SPADE) measurement scheme for far-field incoherent optical imaging under the effects of diffraction and photon shot noise. Building on previous results that assume two point sources or the Gaussian point-spread function, I generalize SPADE for a larger class of point-spread functions and evaluate its errors in estimating the moments of an arbitrary subdiffraction object. Compared with the limits to direct imaging set by the Cramér-Rao bounds, the results show that SPADE can offer far superior accuracy in estimating the second and higher-order moments.

description: Optical excitation at terahertz frequencies has emerged as an effective means to manipulate complex solids dynamically. In the molecular solid K3C60, coherent excitation of intramolecular vibrations was shown to transform the high temperature metal into a non-equilibrium state with the optical conductivity of a superconductor. Here we tune this effect with hydrostatic pressure, and we find it to disappear around 0.3 GPa. Reduction with pressure underscores the similarity with the equilibrium superconducting phase of K3C60, in which a larger electronic bandwidth is detrimental for pairing. Crucially, our observation excludes alternative interpretations based on a high-mobility metallic phase. The pressure dependence also suggests that transient, incipient superconductivity occurs far above the 150 K hypothesised previously, and rather extends all the way to room temperature.

description: We show that the $N$-particle Sutherland model with inverse-square and harmonic interactions exhibits orthogonality catastrophe. For a fixed value of the harmonic coupling, the overlap of the $N$-body ground state wave functions with two different values of the inverse-square interaction term goes to zero in the thermodynamic limit. When the two values of the inverse-square coupling differ by an infinitesimal amount, the wave function overlap shows an exponential suppression. This is qualitatively different from the usual power law suppression observed in the Anderson's orthogonality catastrophe. We also obtain an analytic expression for the wave function overlaps for an arbitrary set of couplings, whose properties are analyzed numerically. The quasiparticles constituting the ground state wave functions of the Sutherland model are known to obey fractional exclusion statistics. Our analysis indicates that the orthogonality catastrophe may be valid in systems with more general kinds of statistics than just the fermionic type.

The Emergence of Subradiance in Ensembles of Quantum Optical Emitters

Subjects: classificationCode: 399999
subject: Other education not elsewhere classified

description: Several of the leading quantum technologies are built around harnessing the intrinsic dynamics and interactions between single atoms. One of the key characteristics of these elementary building blocks is their spontaneous decay rate, which quantifies the time that the atom can store energy or information. As predicted by Purcell in 1946 [1], this rate can modified by engineering the environment of the atoms. Alternatively, in complex systems comprising several excited atoms, the decay rate can be similarly increased through the process known as Dicke superradiance [2]. However, decreasing the spontaneous emission rate, and thus increasing the time for which atoms remain excited, turns out to be a difficult challenge. In this work, we attempt to address that challenge, by theoretically investigating the emergence of subradiance – the suppression of dissipation rates from a collection of atomic emitters. To this end, we build a simplified model of relevant experimental systems, such as ensembles of nitrogen-vacancy defects in diamond, as a collection of interacting two-level systems. We trace the dynamics of such systems, and identify the so-called dissipative coupling between emitters as the necessary element for the emergence of the subradiance. We then develop a numerical model for tracing the dynamics of an atomic ensemble in the limit of weak excitations, and use it to study several idealised systems, such as a 1D chain, as well as the more realistic models of a random 2D ensembles of atoms. We identify the subradiance in all these setups, and characterise it as a function of physically-relevant parameters like the number, and spacing between atoms. Our work sets up a larger research program into identifying, and harnessing the subradiant states of atomic ensembles as new elementary building blocks for complex quantum systems.

We identify the interference mechanism that creates the necessary enhanced couplings and bandwidth narrowing of the hybrid resonance and show that it can assist entering into the strong coupling regime. Our results provide new possibilities for improving the efficiency of solid-state emitters and accessing diverse realms of photophysics with hybrid structures that can be fabricated using existing technologies.

description: In order to achieve the high-fidelity quantum control needed for a broad range of quantum information technologies, reducing the effects of noise and system inhomogeneities is an essential task. It is well known that a system can be decoupled from noise or made insensitive to inhomogeneous dephasing dynamically by using carefully designed pulse sequences based on square or delta-function waveforms such as Hahn spin echo or CPMG. However, such ideal pulses are often challenging to implement experimentally with high fidelity. Here, we uncover a new geometrical framework for visualizing all possible driving fields, which enables one to generate an unlimited number of smooth, experimentally feasible pulses that perform dynamical decoupling or dynamically corrected gates to arbitrarily high order. We demonstrate that this scheme can significantly enhance the fidelity of single-qubit operations in the presence of noise and when realistic limitations on pulse rise times and amplitudes are taken into account.

We explain how quantum gas microscopy can be used to detect this phase's non-local string order and its topological edge states. We model the detection process. We also find that this model can display supersolid correlations, but argue that they only occur at parameter values which would be challenging to realize in an experiment.

description: Optical non-linearities usually appear for large intensities, but discrete transitions allow for giant non-linearities operating at the single photon level. This has been demonstrated in the last decade for a single optical mode with cold atomic gases, or single two-level systems coupled to light via a tailored photonic environment. Here we demonstrate a two-modes giant non-linearity by using a three-level structure in a single semiconductor quantum dot (QD) embedded in a photonic wire antenna. The large coupling efficiency and the broad operation bandwidth of the photonic wire enable us to have two different laser beams interacting with the QD in order to control the reflectivity of a laser beam with the other one using as few as 10 photons per QD lifetime. We discuss the possibilities offered by this easily integrable system for ultra-low power logical gates and optical quantum gates.

description: Variable selection is a widely studied problem in high dimensional statistics, primarily since estimating the precise relationship between the covariates and the response is of great importance in many scientific disciplines. However, most of theory and methods developed towards this goal for the linear model invoke the assumption of iid sub-Gaussian covariates and errors. This paper analyzes the theoretical properties of Sure Independence Screening (SIS) (Fan and Lv [J. R. Stat. Soc. Ser. B Stat. Methodol. 70 (2008) 849-911]) for high dimensional linear models with dependent and/or heavy tailed covariates and errors. We also introduce a generalized least squares screening (GLSS) procedure which utilizes the serial correlation present in the data. By utilizing this serial correlation when estimating our marginal effects, GLSS is shown to outperform SIS in many cases. For both procedures we prove sure screening properties, which depend on the moment conditions, and the strength of dependence in the error and covariate processes, amongst other factors. Additionally, combining these screening procedures with the adaptive Lasso is analyzed. Dependence is quantified by functional dependence measures (Wu [Proc. Natl. Acad. Sci. USA 102 (2005) 14150-14154]), and the results rely on the use of Nagaev-type and exponential inequalities for dependent random variables. We also conduct simulations to demonstrate the finite sample performance of these procedures, and include a real data application of forecasting the US inflation rate.

description: We consider globally hyperbolic spacetimes with compact Cauchy surfaces in a setting compatible with the presence of a positive cosmological constant. More specifically, for 3+1 dimensional spacetimes which satisfy the null energy condition and contain a future expanding compact Cauchy surface, we establish a precise connection between the topology of the Cauchy surfaces and the occurrence of past singularities. In addition to (a refinement of) the Penrose singularity theorem, the proof makes use of some recent advances in the topology of 3-manifolds and of certain fundamental existence results for minimal surfaces.

description: The "complexity = action" duality states that the quantum complexity is equal to the action of the stationary AdS black holes within the Wheeler-DeWitt patch at late time approximation. We compute the action growth rates of the neutral and charged black holes in massive gravity and the neutral, charged and Kerr-Newman black holes in $f(R)$ gravity to test this conjecture. Besides, we investigate the effects of the massive graviton terms, higher derivative terms and the topology of the black hole horizon on the complexity growth rate.

description: These are the slides presented and results from a mentimeter survey held at our workshop on "Harmonising Access Procedures for Sensitive data" at the Open Science Conference 2023. This is the description of our workshop: Open Access datasets typically come with creative commons licences that specify the conditions for reuse. For sensitive data, however, access conditions are often strict and much less standardised. More often than not the conditions under which access is granted are unclear to the researcher. Work conducted in the context of the Dutch Open Data Infrastructure for Social Science and Economic Innovations (ODISSEI) aims to address this challenge.

 In this workshop, we want to discuss how existing access procedures and licences associated with sensitivity datasets could be harmonised. We propose an extension of the existing creative commons licences with new licences that summarise the conditions often applied to the reuse of sensitive data. These include, for instance, the verification of the user, their intent, and requirements around the use of secure analysis environments.

 We would like to discuss our initial work and evaluate how well the proposed licences would fit with existing use cases and procedures applied to sensitive data within the Open Science community.

 The workshop starts with a welcome and short introduction of the ODISSEI infrastructure and project in which the work is situated. We would then like to collect use cases from the community that showcase which procedures for access to sensitive data are currently in place and what challenges participants encounter.

 Consecutively, we continue with the presentation of our proposal for managed access licences that we expect could cover some of the identified use cases. After the presentation, we will give the opportunity to discuss and exchange with the audience coming back to the use cases collected in the earlier part of the workshop.

 Our workshop aims to break open the discussion on how access procedures for sensitive data can be harmonised providing protection for sensitive data, but following the principles of Open Science.
Optimal diversification strategies in the networks of related products and of related research areas

description: Countries and cities are likely to enter economic activities that are related to those that are already present in them. Yet, while these path dependencies are universally acknowledged, we lack an understanding of the diversification strategies that can optimally balance the development of related and unrelated activities. Here, we develop algorithms to identify the activities that are optimal to target at each time step. We find that the strategies that minimize the total time needed to diversify an economy target highly connected activities during a narrow and specific time window. We compare the strategies suggested by our model with the strategies followed by countries in the diversification of their exports and research activities, finding that countries follow strategies that are close to the ones suggested by the model. These findings add to our understanding of economic diversification and also to our general understanding of diffusion in networks.

description: We show at one-loop approximation that the QED photon acquires a negative gauge-invariant mass-squared in the near-horizon region of an evaporating Schwarzschild black hole. This result may imply that information about the inner structure of evaporating black holes is accessible, even without invoking the modification of the basic QFT and GR principles.

An approximate empirical Bayesian method for large-scale linear-Gaussian inverse problems

description: We study Bayesian inference methods for solving linear inverse problems, focusing on hierarchical formulations where the prior or the likelihood function depend on unspecified hyperparameters. In practice, these hyperparameters are often determined via an empirical Bayesian method that maximizes the marginal likelihood function, i.e., the probability density of the data conditional on the hyperparameters. Evaluating the marginal likelihood, however, is computationally challenging for large-scale problems. In this work, we present a method to approximately evaluate marginal likelihood functions, based on a low-rank approximation of the update from the prior covariance to the posterior covariance. We show that this approximation is optimal in a minimax sense. Moreover, we provide an efficient algorithm to implement the proposed method, based on a combination of the randomized SVD and a spectral approximation method to compute square roots of the prior covariance matrix. Several numerical examples demonstrate good performance of the proposed method.
