What Do Human Rights Mean for Citizenship Education?
Creators: name: Fritzsche, K. Peter
Publisher: name: JSSE - Journal of Social Science Education
Year: 2008

description: The article argues that citizenship education and human rights education can be understood as educational responses to specific social and political challenges in different national, regional and global contexts. It outlines four cases: (1) Nbsp; the early German response of civic education; (2) The late British response of citizenship education; (3) The response of EDC within the European framework of the Council of Europe; (4) The response of HRE within the global framework of the UN and the UNESCO. The main aim is to contribute to the necessary clarification of what is shared and what is different of EDC and HRE in this ongoing process of cooperation and integration between the two approaches in Europe.

description: We investigate the evolution of two bars formed in fully self-consistent hydrodynamic simulations of the formation of Milky Way-mass galaxies. One galaxy shows higher central mass concentration and has a longer and stronger bar than the other at $z = 0$. The stronger bar evolves by transferring its angular momentum mainly to the dark halo. Consequently the rotation speed of the bar decreases with time, while the amplitude of the bar increases with time. These features qualitatively agree with the results obtained by idealized simulations. The pattern speed of the stronger bar largely goes up and down within a half revolution in its early evolutionary stage. These oscillations occur when the bar is misaligned with the $m = 4$ mode Fourier component. These oscillations correlate with the oscillations in the triaxilality of the dark matter halo, but differently from the way identified by idealized simulations. The amplitude of the weaker bar does not increase despite the fact that its rotation slows down with time.This result contradicts what is expected from idealized simulations and is caused by the decline of the central density associated with the mass loss and feedback from the stellar populations. The amplitude of the weaker bar is further weakens by the angular momentum injection by the interactions with stellar clumps in the disk. In the both galaxies, the bars are terminated around the 4:1 resonance.

Year: 2008

description: Citizenship education in Turkey has been a part of the state-centric modernization project involving the transformation of public and private lives of Turkish citizens. Although there has always been a separate course on civics, citizenship education emerges as a cross-curricular theme in the Turkish educational system which aims at creating a self-sacrificing and patriotic citizen. Besides its particularistic content, however, Turkish citizenship education also involves references to a universal conception of citizenship in line with Turkey’s aspiration to be a member of the European Union. This paper presents a historical frame and breaking points for citizenship education in Turkey from its foundation to the present. It critically examines paradoxical content of the current citizenship and human rights education curriculum.

description: In this work we investigate a generalized tunneling barrier for planar emitters at zero-temperature. We present the evidence of the emergence of a non-Fowler-Nordheim-type general behavior for the field emission current density in the case that the Fermi energy ($μ$) is comparable with or smaller that the decay width ($d_F$). Therefore, for some non-metals or materials that have very small Fermi energy the standard Fowler-Nordheim-type theory may require a correction. In the opposite regime, i.e., for $μ$ much larger that $d_F$, we confirm that the conventional theory is suitable for metals.

description: Gross-Pandharipande-Siebert have shown that the 2-dimensional Kontsevich-Soibelman scattering diagrams compute certain genus zero log Gromov-Witten invariants of log Calabi-Yau surfaces. We show that the $q$-refined 2-dimensional Kontsevich-Soibelman scattering diagrams compute, after the change of variables $q=e^{i \hbar}$, generating series of certain higher genus log Gromov-Witten invariants of log Calabi-Yau surfaces. This result provides a mathematically rigorous realization of the physical derivation of the refined wall-crossing formula from topological string theory proposed by Cecotti-Vafa, and in particular can be seen as a non-trivial mathematical check of the connection suggested by Witten between higher genus open A-model and Chern-Simons theory. We also prove some new BPS integrality results and propose some other BPS integrality conjectures.

Subjects: subject: Hardware Update

description: In the software domain, updating applications after the product has been delivered to the customer is a common strategy to decrease the time-to-market and continuously improve the quality of the product. In the hardware sector, where time-to-market is generally longer, this strategy is not yet used due to technological barriers. This thesis presents a platform that allows post-sales hardware updates for Internet-of-Things (IoT) devices using dynamic partial reconfiguration. To demonstrate this platform in practice, we use an application using an Early Warning Score (EWS) system to determine a patient’s state of health as a showcase. The proposed platform not only allows updating the hardware design post-sales, but also includes dynamic partial reconfiguration capabilities that allows the updated designs, in this case Fourier Transform, used on the device to be changed during operations (at runtime). This feature is not only beneficial for hardware updates but it can improve runtime performance of the system too. A use case was shown in which a favourable hardware implementation is automatically configured depending on the battery status of the IoT device in order to adapt the performance of the unit to the runtime requirements (e.g., lower power profile when the battery is low). The performances of these implementations are compared in terms of: power consumption, accuracy, processing speed and utilisation.

Relations de Hodge--Riemann et combinatoire des matroïdes (d'après K. Adiprasito, J. Huh et E. Katz)

description: Finite matroids are combinatorial structures that express the concept of linear independence. In 1964, G.-C. Rota conjectured that the coefficients of the "characteristic polynomial" of a matroid $M$, polynomial whose coefficients enumerate its subsets of given rank, form a log-concave sequence. K. Adiprasito, J. Huh et E. Katz have proved this conjecture using methods which, although entirely combinatorial, are inspired by algebraic geometry. From the Bergman fan of the matroid $M$, they define a graded "Chow ring" $A(M)$ for which they prove analogs of the Poincaré duality, the Hard Lefschetz theorem, and the Hodge--Riemann relations. The sought for log-concavity inequalities are then analogous to the Khovanskii--Teissier inequalities.

description: The recent growth of interest in children’s participation in civic life, partly reflected in and stimulated by the UN Convention on the Rights of the Child (CRC), has led to concerns about how to facilitate the involvement and participation of young people in public life and in the public policy process. Young people are fully capable of involvement in community assessment, planning and decision making. Research around the world shows that they gravitate naturally to a purposeful engagement with their surroundings and have strong feelings about the local environments they use everyday. Particularly, living in a foreign cultural context requires more involvement in order to accommodate to the culture. Turkish children and young people living in Germany are dealing with many problems, including their civic engagements. In this research, 40 pre-adolescents were interviewed in order to investigate their cultural participation in Germany. In-depth-interviews are done and analysed. Results show that the young people have a strong wish to be listened, particularly on issues directly affecting their daily lives and activities, their education, school and the environment they live. In this article the results will be discussed and examples will be given.

description: The geometrical structure known as Tulczyjew triple has been used with success in analytical mechanics and first order field theory to describe a wide range of physical systems including Lagrangian/Hamiltonian systems with constraints and/or sources, or with singular Lagrangian. Starting from the first principles of the variational calculus we derive Tulczyjew triples for classical field theories of arbitrary high order, i.e. depending on arbitrary high derivatives of the fields. A first triple appears as the result of considering higher order theories as first order ones with configurations being constrained to be holonomic jets. A second triple is obtained after a reduction procedure aimed at getting rid of nonphysical degrees of freedom. This picture we present is fully covariant and complete: it contains both Lagrangian and Hamiltonian formalisms, in particular the Euler-Lagrange equations. Notice that, the required Geometry of jet bundles is affine (as opposed to the linear Geometry of the tangent bundle). Accordingly, the notions of affine duality and affine phase space play a distinguished role in our picture. In particular the Tulczyjew triples in this paper consist of morphisms of double affine-vector bundles which, moreover, preserve suitable presymplectic structures.

Moreover, this impact will also be seen through recent policies and state initiatives on citizenship education, as well as on higher education institutions and NGOs in their contribution to these initiatives. These analyses point to the need for a more systematic intervention in teachers’ education on citizenship education and on schools initiatives in this area.

Asymmetric kink scattering in a two-component scalar field theory model

description: In this paper the kink scattering in a two-component scalar field theory model in (1+1)-Minkowskian space-time is addressed. The potential term $U(ϕ_1,ϕ_2)$ is given by a polynomial of fourth degree in the first field component and of sixth degree in the second one. The novel characteristic of this model is that the kink variety describes two different types of extended particles. These particles are characterized by its topological charge but also by a new feature determined by a discrete charge $Λ=0,\pm 1$. For this reason, the kink scattering involves a very rich variety of processes, which comprises kink annihilation, reflection, charge exchange, transmutation, etc. It has been found that not only the final velocity of the scattered kinks, but also the final nature of the emerging lumps after the collision are very sensitive on the initial velocities. Asymmetric scattering processes arise when Type I and Type II particles are obliged to collide. In this case, ten different final scenarios are possible. Symmetric scattering events are also discussed.

description: Bilayer graphene subjected to perpendicular magnetic and electric fields displays a subtle competition between different symmetry broken phases, resulting from an interplay between the internal spin and valley degrees of freedom. The transition between different phases is often identified by an enhancement of the conductance. Here, we propose that the enhanced conductance at the transition is due to the appearance of robust conducting edge states at domain walls between the two phases. We formulate a criterion for the existence of such conducting edge states at the domain walls. For example, for a spontaneously layer polarized state at filling factor $ν=2$, domain walls between regions of opposite polarization carry conducting edge modes. A microscopic analysis shows that lattice-scale interactions can favor such a layer polarized state.

description: Analysis of a flanged pipe joint subjected to bending and determination of maximum bolt tension is a rather difficult task due to absence of a rational method of analysis. Conventionally, in absence of specific guideline or code provisions, a method analogous to beam flexure is adopted to determine bolt tension. It is assumed that bolt force (tension or compression) is linearly proportional to the distance from the neutral axis. But this method may not always give the accurate result since the assumptions made are not practically valid. In this research, an investigation has been made to find out the effect of various parameters relating to flanged pipe joint connection, so that a guideline can be developed to determine the bolt tension. To carry out the investigation, a flanged pipe joint subjected to bending has been modeled using finite element method, which also includes contact simulation. In this analysis, shell element has been used for the modeling of pipe and flange, nonlinear spring contact element to model flange-flange contact and linear spring element is used to model bolt shanks. Here nonlinear finite element method has been used considering material nonlinearity only. The pipe joint has been subjected to yield moment and under this moment the maximum bolt tension has been evaluated. Based on overall study, an attempt has been made to present a guideline to find out bolt tension that is structurally effective for a flanged pipe joint. The whole process is carried out for various parameters within certain range. It has been found that some parameters like flange thickness, flange width and diameter of bolt have significant effect on effective bolt tension. Based on the results of the finite element analysis, an empirical equation has been developed to determine the maximum bolt tension. It also has been shown that the suggested empirical equation is useful in structural analysis for calculating the effective bolt tension with acceptable accuracy when the flanged pipe joint is subjected to bending.

Rotation, inflation, and lithium in the Pleiades

description: The rapidly rotating cool dwarfs of the Pleiades are rich in lithium relative to their slowly rotating counterparts. Motivated by observations of inflated radii in young, active stars, and by calculations showing that radius inflation inhibits pre-main sequence (pre-MS) Li destruction, we test whether this pattern could arise from a connection between stellar rotation rate and radius inflation on the pre-MS. We demonstrate that pre-MS radius inflation can efficiently suppress lithium destruction by rotationally induced mixing in evolutionary models, and that the net effect of inflation and rotational mixing is a pattern where rotation correlates with lithium abundance for $M_{*} < {\rm M}_{\odot}$, and anti-correlates with lithium abundance for $M_{*} > {\rm M}_{\odot}$, similar to the empirical trend in the Pleiades. Next, we adopt different prescriptions for the dependence of inflation on rotation, and compare their predictions to the Pleiades lithium/rotation pattern. We find that if a connection between rotation and radius inflation exists, then the important qualitative features of this pattern naturally and generically emerge in our models. This is the first consistent physical model to date that explains the Li--rotation correlation in the Pleiades. We discuss plausible mechanisms for inducing this correlation and suggest an observational test using granulation.

A leakage-resilient approach to fault-tolerant quantum computing with superconducting elements

description: Superconducting qubits, while promising for scalability and long coherence times, contain more than two energy levels, and therefore are susceptible to errors generated by the leakage of population outside of the computational subspace. Such leakage errors constitute a prominent roadblock towards fault-tolerant quantum computing (FTQC) with superconducting qubits. FTQC using topological codes is based on sequential measurements of multiqubit stabilizer operators. Here, we first propose a leakage-resilient procedure to perform repetitive measurements of multiqubit stabilizer operators, and then use this scheme as an ingredient to develop a leakage-resilient approach for surface code quantum error correction with superconducting circuits. Our protocol is based on swap operations between data and ancilla qubits at the end of every cycle, requiring read-out and reset operations on every physical qubit in the system, and thereby preventing persistent leakage errors from occurring.

description: L’immigration est, avec l’écologie, un thème brûlant qui met sérieusement à mal notre humanisme et notre avenir. Nous avons tous la lourde responsabilité d’en comprendre les enjeux afin de pouvoir nous positionner avec clairvoyance, trouver les moyens de mieux vivre ensemble et en meilleure harmonie avec notre environnement, sans toutefois tomber dans l’idéalisme ou la démesure. Le système éducatif est le lieu par excellence où de telles problématiques peuvent/doivent être abordées d’autant que de nombreux écrivains, philosophes ou artistes ont été/sont préoccupés par de tels sujets et ceci de tous temps. Ce travail présente une séquence de cours autour de l’immigration, tout en faisant découvrir aux élèves les positions d’artistes et de rappeurs contemporains qui ont percé sur la scène internationale, et ceci en les initiant à l’art de l’argumentation. L’enjeu est triple : celui de mieux comprendre un sujet qui a des ramifications étendues et concerne notre aptitude à nous ouvrir au monde ; découvrir des oeuvres clefs de notre siècle; apprendre les éléments de base d’un art rhétorique ancien qui continue à jouer un rôle central dans nos existences. C’est l’occasion de découvrir le documentaire d’un rappeur sénégalais, Didier Awadi ; le travail d’un peintre d’origine sud-africaine installé à Paris, Bruce Clarke ; l’approche d’un artiste chinois dont le travail a été exposé à Lausanne, Ai Weiwei ; la composition d’un rappeur franco-congolais convertit au soufisme, Abd Al Malik. J’espère également démontrer, comme je l’indique dans ma conclusion, l’importance d’aborder diverses formes d’art, autant le visuel que le verbal, ouvrant les élèves aux approches artistiques, ce qui en retour leur permet de mieux cerner des problématiques d’une rare complexité. Ainsi en valorisant l’interdisciplinarité et l’interculturel, nous défrichons les fondements même de l’argumentation qui est l’art de l’ouverture, de la concession, de la prise en compte, du respect afin d’être tout simplement mieux entendu.

description: We find the automorphism group of the moduli space of parabolic bundles on a smooth curve (with fixed determinant and system of weights). This group is generated by: automorphisms of the marked curve, tensoring with a line bundle, taking the dual, and Hecke transforms (using the filtrations given by the parabolic structure). A Torelli theorem for parabolic bundles with arbitrary rank and generic weights is also obtained. These results are extended to the classification of birational equivalences which are defined over "big" open subsets (3-birational maps, i.e. birational maps giving an isomorphism between open subsets with complement of codimension at least 3). Finally, an analysis of the stability chambers for the parabolic weights is performed in order to determine precisely when two moduli spaces of parabolic vector bundles with different parameters (curve, rank, determinant and weights) can be isomorphic.

description: In den letzten Jahrzehnten ist so manches Mal die Bedeutung einer „europäischen Identität” unterstrichen worden, manches Mal, um die Distanz der Bürger zum europäischen Projekt zu übrebrücken; andere Mal, um die Vertiefung dieses Projektes überhaupt zu ermöglichen. Der Autor unterzieht diesen Begriff einer kritischen Überprüfung, im Rahmen der Problematik der kollektiven Identitäten überhaupt, und unterscheidet zwischen Identität und Identifizierung, deren Bedeutung unterstrichen wird. Gefragt wird wie diese zu vermitteln sei und welche Rolle dabei die Erziehung spiele. Schliesslich wird auch Bezug auf die Allgemeinbildung genommen und speziell auf die Kenntnis des sogenannten „europäischen Erbes.” In the last decades, the claim for a "European identity" has been manifested sometimes as a solution for the citizens' distance to the European project, sometimes also as a precondition for a further development of the project itself. The paper submits these manifestations to a critical evaluation, bringing to the fore some prob-lems connected with the concept of collective identity. It distinguishes between identity and identification, underlines the relevance of the last one and asks how to implement this identification and in which way the education can contribute to this effort. The knowledge of the cultural heritage is underlined.

description: In the time evolution of isolated quantum systems out of equilibrium, local observables generally relax to a long-time asymptotic value, governed by the expectation values (diagonal matrix elements) of the corresponding operator in the eigenstates of the system. The temporal fluctuations around this value, response to further perturbations, and the relaxation toward this asymptotic value, are all determined by the off-diagonal matrix elements. Motivated by this non-equilibrium role, we present generic statistical properties of off-diagonal matrix elements of local observables in two families of interacting many-body systems with local interactions. Since integrability (or lack thereof) is an important ingredient in the relaxation process, we analyze models that can be continuously tuned to integrability. We show that, for generic non-integrable systems, the distribution of off-diagonal matrix elements is a gaussian centered at zero. As one approaches integrability, the peak around zero becomes sharper, so that the distribution is approximately a combination of two gaussians. We characterize the proximity to integrability through the deviation of this distribution from a gaussian shape. We also determine the scaling dependence on system size of the average magnitude of off-diagonal matrix elements.

But it may simply mirror the real vanishing of sociological topics from civic education curricula in the past decades occurring at least in some European countries.

description: In this paper the scattering between the non-topological kinks arising in a family of two-component scalar field theory models is analyzed. A winding charge is carried by these defects. As a consequence, two different classes of kink scattering processes emerge: (1) collisions between kinks that carry the same winding number and (2) scattering events between kinks with opposite winding number. The variety of scattering channels is very rich and it strongly depends on the collision velocity and the model parameter. For the first type of events, four distinct scattering channels are found: \textit{kink reflection} (kinks collide and bounce back), \textit{one-kink (partial) annihilation} (the two non-topological kinks collide causing the annihilation of one half of each kink and the subsequent recombination of the other two halves, giving rise to a new non-topological kink with the opposite winding charge), \textit{winding flip kink reflection} (kinks collide and emerge with the opposite winding charge) and \textit{total kink annihilation} (kinks collide and decay to the vacuum configuration). For the second type of events, the scattering channels comprise \textit{bion formation} (kink and antikink form a long-living bound state), \textit{kink-antikink passage} (kinks collide and pass each other) and \textit{kink-antikink annihilation} (kink and antikink collide and decay to the vacuum configuration).

description: We present initial pulsar results from the first station of the Long Wavelength Array (LWA1) obtained during the commissioning period of LWA1 and early science results. We present detections of periodic emission from 44 previously known pulsars, including 3 millisecond pulsars (MSPs). The effects of the interstellar medium on pulsar emission are significantly enhanced at the low frequencies of the LWA1 band (10--88 MHz), making LWA1 a very sensitive instrument for characterizing changes in dispersion measures (DM) and other effects from the interstellar medium. Pulsars also often have significant evolution in their pulse profile at low frequency and a break in their spectral index. We report DM measurements for 44 pulsars, mean flux density measurements for 36 pulsars, and multi-frequency component spacing and widths for 15 pulsars with more than one profile component. For 27 pulsars, we report spectral index measurements within our frequency range. We also introduce the LWA1 Pulsar Data Archive, which stores reduced data products from LWA1 pulsar observations. Reduced data products for the observations presented here can be found on the archive. Reduced data products from future LWA1 pulsar observations will also be made available through the archive.

description: The effectiveness of biosignal generation and data augmentation with biosignal generative models based on generative adversarial networks (GANs), which are a type of deep learning technique, was demonstrated in our previous paper. GAN-based generative models only learn the projection between a random distribution as input data and the distribution of training data.Therefore, the relationship between input and generated data is unclear, and the characteristics of the data generated from this model cannot be controlled. This study proposes a method for generating time-series data based on GANs and explores their ability to generate biosignals with certain classes and characteristics. Moreover, in the proposed method, latent variables are analyzed using canonical correlation analysis (CCA) to represent the relationship between input and generated data as canonical loadings. Using these loadings, we can control the characteristics of the data generated by the proposed method. The influence of class labels on generated data is analyzed by feeding the data interpolated between two class labels into the generator of the proposed GANs. The CCA of the latent variables is shown to be an effective method of controlling the generated data characteristics. We are able to model the distribution of the time-series data without requiring domain-dependent knowledge using the proposed method. Furthermore, it is possible to control the characteristics of these data by analyzing the model trained using the proposed method. To the best of our knowledge, this work is the first to generate biosignals using GANs while controlling the characteristics of the generated data.
Social Theory: Who Needs It? A Didactic Substantiation of Social Theories in Lessons
Creators: name: Zurstrassen, Bettina
Publisher: name: JSSE - Journal of Social Science Education

description: Only marginal importance is attached to the analysis of social theories in textbooks for social science. Mostly, they are only taught in extracts, and the analysis of a text extract from a theory is seldom discussed in class. In particular, sociological theories are therefore only presented to the pupils in an abridged form. The didactic-methodical potential of social theories in the process of Conceptual Change – from the everyday theory to science-related theories – about aspects of social changes, the social order, or social actions, remains unused. This article deals with scientific, didactic and methodical questions on the use of social theories in social science lessons.

description: Ce mémoire professionnel contribue à l’intégration du numérique dans l’enseignement ainsi que le demande la nouvelle conseillère d’État, Cesla Amarelle. En effet, notre travail a pour mission de légitimer l’utilisation de la plateforme Pinterest en tant qu’outil didactique dans le cadre de l’enseignement du français en secondaire II. Ce réseau social permet notamment de créer des tableaux thématiques virtuels afin d’épingler un certain nombre d’illustrations répertoriées autour d’une idée et auxquelles il est possible d’accéder ultérieurement. Dans notre travail, nous proposons d’utiliser la plateforme susmentionnée dans le but d’améliorer les performances de lecture des élèves. Plus précisément, nous nous sommes intéressés à l’importance de l’imagerie mentale lors du processus de lecture répertoriée sous l’appellation « processus d’élaboration » par Giasson (1990). Selon cette dernière, l’incarnation des mots par l’image favorise une compréhension fine des textes littéraires et in extenso une analyse microtextuelle de qualité. A partir de ce constat, nous avons créé une séquence d’enseignement et d’apprentissage autour du roman À rebours de Joris-Karl Huysmans, parangon de la littérature décadente et symboliste. Cette oeuvre difficile d’accès se fonde sur de nombreuses descriptions imagées et culturellement inscrites, ce dernier point étant précisément un obstacle à la compréhension du texte par les élèves. C’est ainsi que nous postulons que la création d’un musée virtuel par les étudiants sur la plateforme Pinterest contribuerait à une appropriation du sens profond d’À rebours et, plus généralement, de tous les textes à forte dimension visuelle au premier rang desquels se trouvent les pièces poétiques. Parallèlement, le dispositif proposé présente un certain nombre d’avantages pédagogiques, puisqu’il favorise, d’un côté, la création d’une dynamique collaborative et, d’un autre côté, la découverte d’un nouveau moyen d’apprentissage moderne souvent méconnu par les élèves.
Minimizing the expected value of the asymmetric loss and an inequality of the variance of the loss

description: For some estimations and predictions, we solve minimization problems with asymmetric loss functions. Usually, we estimate the coefficient of regression for these problems. In this paper, we do not make such the estimation, but rather give a solution by correcting any predictions so that the prediction error follows a general normal distribution. In our method, we can not only minimize the expected value of the asymmetric loss, but also lower the variance of the loss.
On the rotation curves for axially symmetric disk solutions of the Vlasov-Poisson system

description: A large class of flat axially symmetric solutions to the Vlasov-Poisson system is constructed with the property that the corresponding rotation curves are approximately flat, slightly decreasing or slightly increasing. The rotation curves are compared with measurements from real galaxies and satisfactory agreement is obtained. These facts raise the question whether the observed rotation curves for disk galaxies may be explained without introducing dark matter. Furthermore, it is shown that for the ansatz we consider stars on circular orbits do not exist in the neighborhood of the boundary of the steady state.

description: Le présent travail porte sur l’étude de l’importance d’utiliser le texte littéraire, en particulier le genre poétique, dans l’enseignement et l’apprentissage d’une langue/culture étrangère, l’italien en l’occurrence. En premier lieu, il s’agira d’exposer un cadre théorique légitimant l’usage de ces textes en classe, puis de proposer une série d’activités didactiques autour de la poésie et enfin, porter un regard critique sur ces dernières, en lien avec les éléments théoriques préalablement exposés. La perspective préconisée au sein de ce travail se propose de revisiter la manière d’amener la poésie en classe de langue/culture étrangère et de revoir les objectifs liés à ce genre textuel dans une vision nouvelle, guidée par la motivation de l’apprenant, dont le statut et la considération qu’on a de lui se montrent sous un autre jour.

description: We numerically study level statistics of disordered interacting quantum many-body systems. A two-parameter plasma model which controls level repulsion exponent $β$ and range $h$ of interactions between eigenvalues is shown to reproduce accurately features of level statistics across the transition from ergodic to many-body localized phase. Analysis of higher order spacing ratios indicates that the considered $β$-$h$ model accounts even for long range spectral correlations and allows to obtain a clear picture of the flow of level statistics across the transition. Comparing spectral form factors of $β$-$h$ model and of a system in the ergodic-MBL crossover, we show that the range of effective interactions between eigenvalues $h$ is related to the Thouless time which marks the onset of quantum chaotic behavior of the system. Analysis of level statistics of random quantum circuit which hosts chaotic and localized phases supports the claim that $β$-$h$ model grasps universal features of level statistics in transition between ergodic and many-body localized phases also for systems breaking time-reversal invariance.
