description: Multi-human multi-robot (MH-MR) systems have the ability to combine the potential advantages of robotic systems with those of having humans in the loop. Robotic systems contribute precision performance and long operation on repetitive tasks without tiring, while humans in the loop improve situational awareness and enhance decision-making abilities. A system's ability to adapt allocated workload to changing conditions and the performance of each individual (human and robot) during the mission is vital to maintaining overall system performance. Previous works from literature including market-based and optimization approaches have attempted to address the task/workload allocation problem with focus on maximizing the system output without regarding individual agent conditions, lacking in real-time processing and have mostly focused exclusively on multi-robot systems. Given the variety of possible combination of teams (autonomous robots and human-operated robots: any number of human operators operating any number of robots at a time) and the operational scale of MH-MR systems, development of a generalized framework of workload allocation has been a particularly challenging task. In this paper, we present such a framework for independent homogeneous missions, capable of adaptively allocating the system workload in relation to health conditions and work performances of human-operated and autonomous robots in real-time. The framework consists of removable modular function blocks ensuring its applicability to different MH-MR scenarios. A new workload transition function block ensures smooth transition without the workload change having adverse effects on individual agents. The effectiveness and scalability of the system's workload adaptability is validated by experiments applying the proposed framework in a MH-MR patrolling scenario with changing human and robot condition, and failing robots.

description: In this paper the scattering between a wobbling kink and a wobbling antikink in the standard $ϕ^4$ model is numerically investigated. The dependence of the final velocities, wobbling amplitudes and frequencies of the scattered kinks on the collision velocity and on the initial wobbling amplitude is discussed. The fractal structure becomes more intricate due to the emergence of new resonance windows and the splitting of those arising in the non-excited kink scattering. Outside this phase the final wobbling amplitude exhibits a linear dependence of the collision velocity whereas the final frequency is a decreasing function. By contrast these magnitudes are almost independent of the initial wobbling amplitude.

description: Nowadays, the creative industry in Kazakhstan is a young direction of the economy. The government supports this industry with tax benefits, the provision of infrastructure, as well as the creation of Special Economic Zones (SEZ) in large megacities of the country like Nur-Sultan (Astana) and Almaty. "Astana Hub” and the park of innovative technologies “Alatau" are the main centers of development of the organization of the ICT industry as cluster formations. In this paper, an overview study was conducted to determine the role of these SEZs for the development of the creative industry in Kazakhstan. Firstly, the concept of the creative industry was considered, then a literary review of the creative industry and special economic zones was conducted, and thirdly, a review was made on special economic zones that contribute to the development of the creative industry in Kazakhstan

Principal Components of CMB non-Gaussianity

description: The skew-spectrum statistic introduced by Munshi & Heavens (2010) has recently been used in studies of non-Gaussianity from diverse cosmological data sets including the detection of primary and secondary non-Gaussianity of Cosmic Microwave Background (CMB) radiation. Extending previous work, focussed on independent estimation, here we deal with the question of joint estimation of multiple skew-spectra from the same or correlated data sets. We consider the optimum skew-spectra for various models of primordial non-Gaussianity as well as secondary bispectra that originate from the cross-correlation of secondaries and lensing of CMB: coupling of lensing with the Integrated Sachs-Wolfe (ISW) effect, coupling of lensing with thermal Sunyaev-Zeldovich (tSZ), as well as from unresolved point-sources (PS). For joint estimation of various types of non-Gaussianity, we use the PCA to construct the linear combinations of amplitudes of various models of non-Gaussianity, e.g. $f^{\rm loc}_{\rm NL},f^{\rm eq}_{\rm NL},f^{\rm ortho}_{\rm NL}$ that can be estimated from CMB maps. Bias induced in the estimation of primordial non-Gaussianity due to secondary non-Gaussianity is evaluated. The PCA approach allows one to infer approximate (but generally accurate) constraints using CMB data sets on any reasonably smooth model by use of a lookup table and performing a simple computation. This principle is validated by computing constraints on the DBI bispectrum using a PCA analysis of the standard templates.

Vom Nachhaltigkeitsdiskurs zum hochschuldidaktischen Kriteriensatz

description: Als regulative Idee impliziert die „Nachhaltigkeitsidee“ eine Reihe geisteswissenschaftlicher Theoreme. Sie gilt daher als überkomplex und konnte bislang hochschuldidaktisch nicht systematisch transformiert wurden. Zur Rede stehen hier begriffliche Großprojekte wie Gerechtigkeit, Verantwortung, Partizipation, Retinität oder Globalität und Interkulturalität, die als Kristallisationspunkte der Nachhaltigkeitsidee die Grundlagentexte, Positionspapiere und Programme durchziehen. Im Anschluss an die heuristische Studie Globalität und Interkulturalität als integrale Bestandteile beruflicher Bildung für eine nachhaltige Entwicklung (GInE, www.ibw.uni-hamburg.de/GInE) wurde ein didaktisches Strukturgitter entworfen, das exemplarische Problemlagen und Dilemmata benennt, so wie Reflexionskategorien für die Hochschuldidaktik in der beruflichen Lehrerbildung zur Diskussion stellt As a regulative concept, the idea of sustainability implies a number of theorems in the field of humanities. It is regarded as supercomplex and, thus, could not yet be systematically transformed in university didactics. Large scale conceptual terms such as justice, responsibility, participation, retinity, globality, and interculturality are at the core of the discussion – terms which run through basic texts, policy papers, and programmes as focal points of the idea of sustainability. With respect to the heuristic study Globality and Interculturality as Integral Elements of a Professional Education for a Sustainable Development (GInE, www.ibw.uni-hamburg.de/GInE), a didactic framework was designed which not only denotes exemplary problems and dilemmata but also puts up categories of reflection for a university didactics aiming at a professional teacher training.

The filters must contain all the dense elements of the semi-Heyting algebra and satisfy an additional technical condition. We also show that in the case of dually hemimorphic semi-Nelson algebras, the filters are not necessary and the category is equivalent to that of dually hemimorphic semi-Heyting algebras.
Revealing divergent length scales using quantum Fisher information in the Kitaev honeycomb model

description: We compute the quantum Fisher information (QFI) associated with two different local operators in the Kitaev honeycomb model, and find divergent behaviour in the second derivatives of these quantities with respect to the driving parameter at the quantum phase transition between the gapped and gapless phases for both fully anti-ferromagnetic and fully ferromagnetic exchange couplings. The QFI associated with a local magnetization operator behaves differently from that associated with a local bond operator depending on whether the critical point is approached from the gapped or gapless side. We show how the behaviour of the second derivative of the QFI at the critical point can be understood in terms of diverging length scales in the correlators of the local generators.

description: Wenn Maßnahmen der unternehmerischen Verantwortung (CSR) über die generelle Ausprägung als Geisteshaltung oder als Öffentlichkeitsarbeit hinausgehen sollen, ist unternehmerisches Nachhaltigkeitsmanagement gefordert. Der zur Erreichung einer nachhaltigen Unternehmensentwicklung in der Regel notwendige organisatorische Wandel erfordert sowohl spezifische interdisziplinäre Managementkenntnisse als auch Fachkenntnisse zu unternehmerischer Nachhaltigkeit, die konventionelle betriebswirtschaftliche Studiengänge nicht bieten. Dieser Beitrag legt die Grundzüge des Studiengangkonzepts des weltweit ersten MBA Studiengangs zu Nachhaltigkeitsmanagement dar. Über die Vermittlung von Fachkenntnissen hinaus spielen sowohl generelle als auch spezifische Soft skills und die Gestaltungskompetenz für interdisziplinäre Projekte eine wesentliche Rolle If corporate social responsibility (CSR) is to exceed the ambition of a general philosophy or to be more than PR, corporate sustainability management is required. The organizational change usually necessary to develop a sustainable organization requires specific interdisciplinary management knowledge as well as knowledge about corporate sustainability. Both are not provided by conventional management programmes. This paper discusses the basic study concept of the worldwide first MBA in sustainability management. Exceeding the teaching of factual knowledge, both, general as well as specific soft skills as well as the competence to organize and lead interdisciplinary projects play a crucial role.

description: Für erfolgreiche und nachhaltige Produktentwicklung reichen heute Marktbeobachtung und Kund/innenbefragungen alleine nicht mehr aus. Mit Verfahren zur partizipativen Produktentwicklung (PPE) können sowohl das kreative Potenzial von Nutzer/innen für die Produktentwicklung erschlossen als auch marktfähige nachhaltige Produkte entwickelt werden. Sie ermöglichen so aktives Nachhaltigkeitsmanagement. Am Beispiel des INNOCOPE-Pilotverfahrens wird diskutiert, wie nachhaltigkeitsbezogene Lernprozesse in PPE-Prozessen initiiert werden können und welche Faktoren dabei wesentlich sind. Insgesamt zeigt sich, dass vor allem die sich wiederholende, direkte und möglichst gleichberechtigte Interaktion von Unternehmensvertreter/innen und von Konsument/innen einen themenbezogenen Wissensaustausch und wechselseitige Lernprozesse ermöglicht. Dabei sind der inhaltliche Aufbau der Treffen und der zeitlich gestaffelte Einsatz von Lernmethoden wesentlich Today, market observation and customer surveys alone do not suffice to develop successful and sustainable products. Methods of participatory product development (PPD) allow to open up the creative potential of users for product development, and to develop marketable sustainable products. Thereby, they support active sustainability management. Taking the INNOCOPE pilot process as an example, we discuss the possibilities and the relevant factors to initiate sustainability- and climate-related learning processes within PPD processes. Our findings indicate that repeated, direct and equitable interaction between company representatives and customers are fundamental for relevant knowledge exchange and mutual learning processes. Other key issues are the thematic structure of the meetings and the timing of learning methods.

description: We study the electron/hole transport in puddle-disordered and rough graphene samples which are subject to in-plane magnetic fields. Previous treatments, mostly devoted to regimes where the electron/hole scattering wavelengths are larger than the surface height correlation length, are based on the use of transport equations with appropriate forms for the collision term. We point out in this work, as a counterpoint, that classical Lorentz force effects, which are expected to hold when the Fermi level is far enough away from the charge neutral point, can be heuristically assessed through disordered Boltzmann equations that contain magnetic-field dependent material derivatives, and keep the zero magnetic-field structure of the collision term. It turns out that the electric conductivity tensor gets a peculiar nondiagonal component, induced by the in-plane magnetic field that crosses the rough topography of the graphene sheet, even if the projected random transverse magnetic field vanishes in the mean. Numerical estimates of the transverse conductivities suggest that they are suitable of observation under conditions which are within the reach of up-to-date experimental methods.

description: The paradigm of P2P (peer-to-peer) economy has emerged in diverse areas. "P2P energy sharing" is a new form of P2P economy in the energy sector, which allows users to establish longer-term sharing arrangements of their local energy resources (e.g., rooftop PVs, home batteries) with joint optimized energy management. In such a P2P setting, a coalition of users is formed for sharing resources in a decentralized manner by self-interested users based on their individual preferences. A likely outcome of decentralized coalition formation will be a stable coalition structure, where no group of users could cooperatively opt out to form another coalition that induces higher preferences to all its members. Remarkably, there exist a number of fair cost-sharing mechanisms (e.g., equal-split, proportional-split, egalitarian and Nash bargaining solutions of bargaining games) that model practical cost-sharing applications with desirable properties, such as the existence of a stable coalition structure with a small strong price-of-anarchy (SPoA) to approximate the social optimum. In this paper, we provide general results of decentralized coalition formation: (1) We establish a logarithmic lower bound on SPoA, and hence, show several previously known fair cost-sharing mechanisms are the best practical mechanisms with minimal SPoA. (2) We show that the SPoA of egalitarian and Nash bargaining cost-sharing mechanisms to match the lower bound. (3) We derive the SPoA of a mix of different cost-sharing mechanisms. (4) We present a decentralized algorithm to form a stable coalition structure. (5) Finally, we apply our general results to P2P energy sharing and present an empirical study of decentralized coalition formation in a real-world project. We study the empirical SPoA, which is observed within 95% of the social optimal cost with coalitions of 2 and 3 users, via fair cost-sharing mechanisms.

description: Il presente articolo si propone di rispondere alla domanda di ricerca: “Quali sono i sentimenti e le motivazioni dei giovani cinesi che abbracciano il movimento tangping?” servendosi di una duplice metodologia: (1) keyword analysis e (2) content analysis di 200 post pubblicati da utenti maggiorenni e appartenenti alla Generazione Z sulla piattaforma cinese di social networking Weibo. L’articolo si sviluppa attorno alle tematiche centrali rilevate dalla raccolta e dall’elaborazione dei dati ottenuti in fase di ricerca, al fine di fornire un quadro analitico per la comprensione del fenomeno e di esplorare le motivazioni profonde che spingono la gioventù cinese ad abbracciare tale movimento. In particolare, la ricerca evidenzia tre macroaree principali come cause del disagio nutrito dalla nuova generazione di giovani cinesi: (1) il sistema scolastico; (2) il matrimonio e i valori famigliari tradizionali; e (3) la società e i diritti individuali. Il fenomeno tangping, traducibile come “starsene sdraiati” e ormai virale nella Repubblica popolare cinese, è un movimento recente nato nel 2021 in seguito a un post pubblicato su Weibo, il quale descrive un sentimento di scoramento e disillusione generale nei confronti della società cinese contemporanea e del mondo del lavoro. Tali sentimenti stanno spingendo l’autore del post e, assieme a lui, molti altri giovani cinesi a “fare un passo indietro” dalla società, rassegnandosi di fronte a un contesto socioeconomico iper-competitivo e godendosi la vita.

Social media accountings: dal ruolo di stakeholder virtuale a quello di engaged. Un'esplorazione alla luce della teoria degli stakeholder

description: L’articolo indaga la dimensione del processo dello “stakeholder enga­gement” nel contesto dei social media, tenendo presente l’approccio dello “stakeholder management” partendo dai suoi autori più “clas­sici” (Freeman, 1984; Freeman et al., 2010). Nello specifico si utilizzerà il caso di Instagram per comprendere qual è il ruolo degli stakeholder virtuali nelle interazioni con la pubblica amministrazione. Tramite la "virtual field case study", si prende in esame il materiale empirico per l’analisi del processo di engagement degli stakeholder tramite 3.000 post pubblicati in Instagram, per un periodo di osservazione di nove mesi (Luglio 2019 – Marzo 2020). Il contributo in letteratura si inserisce e prende in considerazione gli studi nell’ambito del social accounting nel contesto dello stakeholder engagement (Unerman & Bennet, 2004; Unerman, 2007; Rusconi, 2007) come uno strumento di accountability e dialogo, contribuendo alla comprensione, alla definizione e all’analisi del "processo di engagement". Tramite i social media si esplora la ge­stione dell’accountability verificando come tale processo funziona nel fornire informazioni; lo studio rientra, pertanto, nell’ambito dello stakeholder management, anche dal punto di vista della sua visione del rapporto tra etica e business (a partire da Freeman, 1994 e Donaldson & Preston, 1995). Questo esame del processo di engagement implica: i) la comprensione del processo e delle sue motivazioni, tramite la creazione della mappatura degli stakeholder virtuali, ii) la definizione del processo di engagement con la considerazione e classificazione dei contenuti condivisi.

description: Die seit mehr als einem Jahrzehnt geführte Debatte über die Zukunft der Deutschen Bahn AG zeigt, dass das Themenfeld „Bahn“ zahlreiche Anknüpfungspunkte bietet, um verschiedene ökonomische Fragestellungen zu beleuchten – gerade auch im Kontext der ökologischen Nachhaltigkeitsbildung. Mit einer didaktisch und methodisch durchdachten Annäherung an das Themenfeld „Bahn“ kann dem gut begründeten, aber häufig unzureichend umgesetzten Postulat, Wissenschafts- und Schülerorientierung miteinander zu verbinden, Rechnung getragen werden. Denn die immense Bandbreite an Zugangs-, Erklärungs- und Interpretationsebenen erlaubt es nicht nur, das Umweltbewusstsein von Schüler(inne)n zu schärfen. Werden Anleitungen zum Fahrscheinkauf erstellt, Statistiken zu Verkehrsmarktanteilen ausgewertet und Schaubilder zu externen Verkehrskosten erörtert, können Kinder und Jugendliche auch motiviert werden, die Bahn als Transportmittel ihrer Wahl zu entdecken und somit einen nachhaltigen Beitrag zum Umwelt- und Klimaschutz zu leisten More than a decade of debate about the future of Germany’s state-run rail company, Deutsche Bahn AG, has shown that the subject of “the railways” provides ample opportunity to discuss a whole range of economic issues, especially in the context of ecological sustainability. The desirable but often inadequately implemented goal of making science accessible to school students can be achieved through a didactically and methodologically well-planned approach, heightening students’ environmental awareness through the immense spectrum of perspectives, explanations and interpretations. And if instructions for buying tickets are prepared, statistics on transport market share analysed and graphics on the external costs of transport explored, children and young people can also be motivated to discover the railways as their preferred means of transport – a lasting contribution to environmental and climate protection.

S’appuyant sur une séquence de quatre leçons, les activités mises en place portent sur 3 aspects, économique, environnementale et éthique, du développement durable et visent à sensibiliser les élèves à ses enjeux. L’objectif final a été dans cette séquence d’amener les élèves à une plus grande prise de conscience de ces enjeux, notamment par rapport à la surconsommation de l’eau en tant que ressource naturelle limitée. Dans le cadre de cette recherche exploratoire, nous avons mis en oeuvre un dispositif d’enseignement interdisciplinaire afin de nous permettre de répondre à la question : « En quoi une approche interdisciplinaire dans le cadre de l’enseignement de la problématique de la surconsommation de l’eau, permet-elle de développer une prise de conscience chez les élèves ? ». A travers l’analyse des traces avant et après la mise oeuvre du dispositif, nous irons voir les pistes évoquées pour répondre à notre question, notamment du point de vue des apprentissages des élèves. Enfin, cette recherche tente de montrer le rôle des médiations (Vygotski, 1934/1985) que l’enseignant « expert » devraient mettre en oeuvre dans un dispositif d’enseignement-apprentissage, notamment en s’appuyant sur son guidage durant l’enseignement, afin d’amener les élèves de l’hétéro-régulation à l’autorégulation.

description: This paper shows the development of a multi-GPU version of a time-explicit finite volume solver for the Shallow-Water Equations (SWE) on a multi-GPU architecture. MPI is combined with CUDA-Fortran in order to use as many GPUs as needed. The METIS library is leveraged to perform a domain decomposition on the 2D unstructured triangular meshes of interest. A CUDA-Aware OpenMPI version is adopted to speed up the messages between the MPI processes. A study of both speed-up and efficiency is conducted; first, for a classic dam-break flow in a canal, and then for two real domains with complex bathymetries: the Mille Îles river and the Montreal archipelago. In both cases, meshes with up to 13 million cells are used. Using 24 to 28 GPUs on these meshes leads to an efficiency of 80% and more. Finally, the multi-GPU version is compared to the pure MPI multi-CPU version, and it is concluded that in this particular case, about 100 CPU cores would be needed to achieve the same performance as one GPU.

Spin-orbit decomposition of ab initio wavefunctions

description: Although the modern shell-model picture of atomic nuclei is built from single-particle orbits with good total angular momentum $j$, leading to $j$-$j$ coupling, phenomenological models suggested decades ago that for $0p$-shell nuclides a simpler picture can be realized via coupling of total spin $S$ and total orbital angular momentum $L$. I revisit this idea with large-basis, no-core shell model (NCSM) calculations using modern \textit{ab initio} two-body interactions, and dissect the resulting wavefunctions into their component $L$- and $S$-components. Remarkably, there is broad agreement with calculations using the phenomenological Cohen-Kurath forces, despite a gap of nearly fifty years and six orders of magnitude in basis dimensions. I suggest $L$-$S$ may be a useful tool for analyzing \textit{ab initio} wavefunctions of light nuclei, for example in the case of rotational bands.

description: We formulate a general SEIR epidemic model in a heterogenous population characterized by some trait in a discrete or continuous subset of a space R d. The incubation and recovery rates governing the evolution of each homogenous subpopulation depend upon this trait, and no restriction is assumed on the contact matrix that defines the probability for an individual of a given trait to be infected by an individual with another trait. Our goal is to derive and study the final size equation fulfilled by the limit distribution of the population. We show that this limit exists and satisfies the final size equation. The main contribution is to prove the uniqueness of this solution among the distributions smaller than the initial condition. We also establish that the dominant eigenvalue of the next-generation operator (whose initial value is equal to the basic reproduction number) decreases along every trajectory until a limit smaller than 1. The results are shown to remain valid in presence of diffusion term. They generalize previous works corresponding to finite number of traits (including metapopulation models) or to rank 1 contact matrix (modeling e.g. susceptibility or infectivity presenting heterogeneity independently of one another).
Does the Democratization of Polities Entail the Democratization of Citizenship Education? A Theoretical Framework for Researching the Democratic Quality of Citizenship Education in Transformation Countries and Elsewhere
Creators: name: Hippe, Thorsten
Publisher: name: JSSE - Journal of Social Science Education

description: In the last 30 years, the process of institutional democratization prevailing in Western Europe since at least the end of World War II has spread to Southwestern, Southeastern and Eastern European countries. To what extent has this democratic transformation of polities been followed by a genuinely democratic transfor-mation of citizenship education in these countries? Unfortunately, recent research on citizenship education does not provide a satisfactory answer, because it has mainly focused on institutional and organizational issues. Nothing was said about the question how well-sounding, but quite general – and therefore ambigu-ous – officially proclaimed goals and contents of citizenship education in transformation countries are educa-tionally construed in textbooks and the teaching practice. However, there are quite a few empirical examples and indications which clearly show that citizenship education in transformation countries (and elsewhere) shows a number of facets which are hardly in line with core democratic values. Therefore, this article pro-poses a theoretical framework for systematically researching the democratic quality of citizenship education in transformation countries (and elsewhere). With recourse to Max Weber`s analytical concept of ideal-types, this framework differentiates between a democratic and a non-democratic ideal-type of citizenship education (as outer points of a continuum between them). These two ideal-types of citizenship education are character-ized by structurally different ways of thinking about 1) human rights, 2) international relations, 3) current insti-tutions and norms, 4) authoritarian political structures and human rights violations in the history of the coun-try, and 5) differences in society.

“Shut Up When You Talkin with Me.” Civil Education in a Post-Communist Society Challenged by the Institutionalized Public Culture. The Case of Bulgaria
Creators: name: Dimitrov, Georgi
Publisher: name: JSSE - Journal of Social Science Education
Year: 2008

description: The paper provides a concise overview of the state of arts of civil education in Bulgaria giving proofs that the contents and values of CE basically contradict the fundamental cultural pattern which is embedded in the institutional design of the school system and the policies of the Ministry of Education. There is a tremendous tension between critical and hypocritical education in democracy. The discrepancy between public “talk” and institutional “action” in civil education is more than overt. This is why the more we concentrate our attention on texts (textbooks, expert publications, manuals for teachers, etc.) the higher level of advancement of CE we will encounter and vice versa – the more we study the school life as practice the less traits of civil culture we register. Hence, the main conclusion is that civil education cannot substitute or get ahead of the democ-ratic institution building; both processes should develop in accord with each other. Or they both would turn out to be abortive.

The Model of Organised Hypocrisy Applied to Romanian Civic Education Policies and Practices
Creators: name: Rus, Calin
Publisher: name: JSSE - Journal of Social Science Education
Year: 2008

description: Behind an apparently positive image, civic education in Romania proves to be an excellent illustration of “organised hypocrisy” (Brunsson, 2002). At a closer look, it becomes obvious that policy decisions related to civic education are isolated responses to various, and often contradictory, pressures from inside and from outside Romania, and that there is a huge gap between policy statements and the school practice, where civic education has a low status and where classical, directive and knowledge-focused pedagogical methods are still widely used.

description: Despite extensive work on high-temperature superconductors, the critical behavior of an incipient condensate has so far been studied exclusively under equilibrium conditions. Here, we excite Bi2Sr2CaCu2O8+d with a femtosecond laser pulse and monitor the subsequent nonequilibrium dynamics of the mid-infrared conductivity. Our data allow us to discriminate temperature regimes where superconductivity is either coherent, fluctuating or vanishingly small. Above the transition temperature Tc, we make the striking observation that the relaxation to equilibrium exhibits power-law dynamics and scaling behavior, both for optimally and underdoped superconductors. Our findings can in part be modeled using time-dependent Ginzburg-Landau theory and provide strong indication of universality in systems far from equilibrium.

TANF Child-Only Policy: Improving Access and Enrollment in Illinois
Creators: name: Taing, Valerie
Publisher: name: Unknown
Year: 2014

description: This paper offers social work practitioners an intersectional analysis of social welfare and immigration policies, through the lens of TANF child-only policy. The paper assesses how TANF child-only grants for Ineligible Immigrant Parent (IIP) cases provide for citizen children and their undocumented parent(s) and makes recommendations for social work practitioners seeking to improve access and enrollment for eligible children. It focuses on the implementation of IIP child-only policy in Illinois and provides recommendations for improving implementation to better serve immigrant children and families.

description: This paper focuses on studying the bifurcation analysis of the eigenstructure of the $γ$-parameterized generalized eigenvalue problem ($γ$-GEP) arising in three-dimensional (3D) source-free Maxwell's equations with Pasteur media, where $γ$ is the magnetoelectric chirality parameter. For the weakly coupled case, namely, $γ< γ_{*} \equiv$ critical value, the $γ$-GEP is positive definite, which has been well-studied by Chern et.\ al, 2015. For the strongly coupled case, namely, $γ> γ_{*}$, the $γ$-GEP is no longer positive definite, introducing a totally different and complicated structure. For the critical strongly coupled case, numerical computations for electromagnetic fields have been presented by Huang et.\ al, 2018. In this paper, we build several theoretical results on the eigenstructure behavior of the $γ$-GEPs. We prove that the $γ$-GEP is regular for any $γ> 0$, and the $γ$-GEP has $2 \times 2$ Jordan blocks of infinite eigenvalues at the critical value $γ_{*}$. Then, we show that the $2 \times 2$ Jordan block will split into a complex conjugate eigenvalue pair that rapidly goes down and up and then collides at some real point near the origin. Next, it will bifurcate into two real eigenvalues, with one moving toward the left and the other to the right along the real axis as $γ$ increases. A newly formed state whose energy is smaller than the ground state can be created as $γ$ is larger than the critical value. This stunning feature of the physical phenomenon would be very helpful in practical applications. Therefore, the purpose of this paper is to clarify the corresponding theoretical eigenstructure of 3D Maxwell's equations with Pasteur media.

description: This study investigates the effect of base isolator on the structural responses of multistoried reinforced concrete building under time history earthquake loading. In the present study, two identical six-storied reinforced concrete buildings with one conventional and the other one is base isolated have been modeled. Conventional building has been modeled with fixed support whereas base-isolated building has been modeled incorporating rubber bearing near the base of all columns. Modal analysis has been performed to get an idea of possible mode shapes of the building. After that time history analysis has been performed in order to investigate the effect of seismic loading on the building structure with respect to time. The structural responses of time history analysis such as time period of different modes, storey displacements, storey acceleration, and base shear have been obtained from both conventional and base-isolated buildings. Finally, a comparative study of structural responses has been carried out between those two structures. It has been found that fundamental time period of base-isolated building is increased by 28% compared to conventional building. Moreover, base shear value of the base-isolated structure is reduced by 69% and top storey acceleration is decreased by 75% compared to conventional building. This study reveals that isolation system reduces seismic responses significantly.
Storage Capacity of Repairable Networks

description: In this paper, we introduce a model of a distributed storage system that is locally recoverable from any single server failure. Unlike the usual local recovery model of codes for distributed storage, this model accounts for the fact that each server or storage node in a network is connectible to only some, and not all other, nodes. This may happen for reasons such as physical separation, inhomogeneity in storage platforms etc. We estimate the storage capacity of both undirected and directed networks under this model and propose some constructive schemes. From a coding theory point of view, we show that this model is approximately dual of the well-studied index coding problem. Further in this paper, we extend the above model to handle multiple server failures. Among other results, we provide an upper bound on the minimum pairwise distance of a set of words that can be stored in a graph with the local repair guarantee. The well-known impossibility bounds on the distance of locally recoverable codes follow from our result.

description: Background: Sports medicine (injury and illnesses) requires distinct coding systems because the International Classification of Diseases is insufficient for sports medicine coding. The Orchard Sports Injury and Illness Classification System (OSIICS) is one of two sports medicine coding systems recommended by the International Olympic Committee. Regular updates of coding systems are required. Methods: For Version 15, updates for mental health conditions in athletes, sports cardiology, concussion sub-types, infectious diseases, and skin and eye conditions were considered particularly important. Results: Recommended codes were added from a recent International Olympic Committee consensus statement on mental health conditions in athletes. Two landmark sports cardiology papers were used to update a more comprehensive list of sports cardiology codes. Rugby union protocols on head injury assessment were used to create additional concussion codes. Conclusion: It is planned that OSIICS Version 15 will be translated into multiple new languages in a timely fashion to facilitate international accessibility. The large number of recently published sport-specific and discipline-specific consensus statements on athlete surveillance warrant regular updating of OSIICS.
Conformastationary disk-haloes in Einstein-Maxwell gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: An exact solution of the Einstein-Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the source is discussed. All the expressions are presented in terms of a solution of the Laplace's equation. A "generalization" of the Kuzmin solution of the Laplace's equations is used as a particular example. The solution obtained is asymptotically flat in general and turns out to be free of singularities. All the relevant quantities show a reasonable physical behaviour.
