description: We present an approximation scheme for optimizing certain Quadratic Integer Programming problems with positive semidefinite objective functions and global lin- ear constraints. This framework includes well known graph problems such as Minimum graph bisection, Edge expansion, Uniform sparsest cut, and Small Set expansion, as well as the Unique Games problem. These problems are notorious for the existence of huge gaps between the known algorithmic results and NP-hardness results. Our algorithm is based on rounding semidefinite programs from the Lasserre hierarchy, and the analysis uses bounds for low-rank approximations of a matrix in Frobenius norm using columns of the matrix. For all the above graph problems, we give an algorithm running in time nO(r/ε2) with approximation ratio (1+ε)/min{1,λr}, where λr is the r'th smallest eigenvalue of the normalized graph Laplacian L. In the case of graph bisection and small set expansion, the number of vertices in the cut is within lower-order terms of the stipulated bound. Our results imply (1 + O(ε)) factor approximation in time nO(r*/ε2) where r* is the number of eigenvalues of L smaller than 1 - ε. This perhaps gives some indication as to why even showing mere APX-hardness for these problems has been elusive, since the reduction must produce graphs with a slowly growing spectrum (and classes like planar graphs which are known to have such a spectral property often admit good algorithms owing to their nice structure). For Unique Games, we give a factor (1 + (2+ε)/λr) approximation for minimizing the number of unsatisfied constraints in nO(r/ε)time. This improves an earlier bound for solving Unique Games on expanders, and also shows that Lasserre SDPs are powerful enough to solve well-known integrality gap instances for the basic SDP. We also give an algorithm for independent set- in graphs that performs well when the Laplacian does not have too many eigenvalues bigger than 1 + o(1).

description: In a mesoscopic system, under zero bias voltage, a finite charge is transferred by quantum adiabatic pumping by adiabatically and periodically changing two or more control parameters. We obtained expressions for the pumped charge for a ring of three quantum dots (QDs) by choosing the magnetic flux penetrating the ring as one of the control parameters. We found that the pumped charge shows a steplike behavior with respect to the variance of the flux. The value of the step heights is not universal but depends on the trajectory of the control parameters. We discuss the physical origin of this behavior on the basis of the Fano resonant condition of the ring.

description: In this work, device performances of tunneling field effect transistors (TFETs) based on phosphorene are explored via self-consistent atomistic quantum transport simulations. Phosphorene is an ultra-thin two-dimensional (2-D) material with a direct band gap suitable for TFETs applications. Our simulation shows that phosphorene TFETs exhibit subthreshold slope (SS) below 60 mV/dec and a wide range of on-current depending on the transport direction due to highly anisotropic band structures of phosphorene. By benchmarking with monolayer MoTe2 TFETs, we predict that phosphorene TFETs oriented in the small effective mass direction can yield much larger on-current at the same on-current/off-current ratio than monolayer MoTe2 TFETs. It is also observed that a gate underlap structure is required for scaling down phosphorene TFETs in the small effective mass direction to suppress the source-to-drain direct tunneling leakage current.

description: HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind nebula powered by one of the most powerful pulsars known in the Galaxy, PSR J1813-1749 with a spin-down luminosity of $\dot{\mathrm{E}} = 5.6 \cdot 10^{37}\,\mathrm{erg}\,\mathrm{s}^{-1}$. With its extreme physical properties, as well as the pulsar's young age of 5.6 kyrs, the $γ$-rays detected in this region allow us to study the evolution of a highly atypical system. Previous studies of the region in the GeV energy range show emission extended beyond the size of the compact H.E.S.S. source. Using the archival H.E.S.S. data with improved background methods, we perform a detailed morphological and spectral analysis of the region. Additionally to the compact, bright emission component, we find significantly extended emission, whose position is coincident with HESS J1813-178. We reanalyse the region in GeV and derive a joint-model in order to find a continuous description of the emission in the region from GeV to TeV. Using the results derived in this analysis, as well as X-ray and radio data of the region, we perform multi-wavelength spectral modeling. Possible hadronic or leptonic origins of the $γ$-ray emission are investigated, and the diffusion parameters necessary to explain the extended emission are examined.

description: Elf Jahre nach Beschlussfassung zur flächendeckenden Einführung der integrativen Schulung (Sonderpädagogik-Konkordat, 2007) zeigt sich für sämtliche Volksschulstufen eine erhebliche Diskrepanz zwischen Soll- und Ist-Bestand an heilpädagogischen Fachpersonen. Nur zwei Drittel der an den Regelschulen mit heilpädagogischen Aufgaben betrauten Fachpersonen verfügen über einen berufsbefähigenden Abschluss in Schulischer Heilpädagogik oder befinden sich in einer entsprechenden Ausbildung. Ursächlich für den Unterbestand an Schulischen Heilpädagoginnen und Heilpädagogen (SHP) ist ein Ineinandergreifen multipler Faktoren und Wirkmechanismen, denen die Einführung der Integrativen Förderung und ein dadurch bedingter Mehrbedarf an SHP ebenso wie eine problemextendierende demografische Entwicklung und ein Zuwachs an Lernenden mit integrierter Sonderschulung (ISR) vorausgehen. Akzentuiert wird die Problematik durch strukturelle Herausforderungen in der Ausbildung zur SHP und wenig attraktive Rahmenbedingungen in der integrativen Schule. Die Ausgestaltung ebendieser Rahmenbedingungen obliegt in wesentlichen Teilen der Schulleitung, die als Entscheidungsträgerin im sonderpädagogischen Bereich die gesetzlich verankerte Integration innerhalb der eigenen Institution zu realisieren und zu verantworten hat. Die vorliegende Arbeit untersucht dahingehend, inwiefern sich Schulleitende der Sekundarstufe I in Bezug auf den Mangel an SHP positionieren und engagieren – differenziert nach Bewusstsein und Wissen, Haltung und konkretem Umgang der Schulleitenden mit den Problemstellungen im Kontext der Personalknappheit an SHP. Grundlage der Untersuchung bilden zehn leitfadengeführte, problemzentrierte Interviews mit Schulleitenden der Sekundarstufe I im Kanton Zürich, ausgewertet mittels qualitativer Inhaltsanalyse nach Mayring. Die Untersuchungsergebnisse verweisen bei den befragten Schulleiterinnen und Schulleitern auf eine Diskrepanz zwischen deklarativem und prozeduralem Wissen hinsichtlich der Bewältigung der Problemstellungen im Zusammenhang mit dem Mangel an SHP. Die Schulleitenden verfügen über ein mässiges bis ausgeprägtes Problembewusstsein sowie über punktuelle Handlungsansätze, für die Umsetzung systematischer Massnahmen zur nachhaltigen Problemlösung fehlt demgegenüber summarisch das Bewusstsein für das eigene Wirkpotenzial ebenso wie ein konkretes Handlungsrepertoire. Die angeführten Ergebnisse der praktischen Erhebung werden im Rahmen der Diskussion den Erkenntnissen und Handlungsansätzen ausgehend der Forschungsliteratur gegenübergestellt, abgeleitet werden Massnahmen zur Optimierung des integrativen Settings und der Effektivität des Einsatzes der SHP im Wirkbereich der Schulleitung ebenso wie Impulse zur Implementierung der Erkenntnisse in Module der Aus- und Weiterbildung von Schulleitenden

description: Project note for work package 06 “Korpusveröffentlichung / Corpus Publishing” produced in the DGS-Korpus project.
 This project note gives an overview of how pose information was created for the Public DGS Corpus with the use of OpenPose. Pose information is machine-readable data that describes where people are located in an image, providing the coordinates for various points of each body, such as joints, eyes or ears. The data we generate consists of body, face and hand models for informants in every camera perspective of all published transcripts.
 Several postprocessing steps were applied to the data before publication. These include a) the correction of errors, such as the false positive recognition of bodies, and recognition of one actual person as two distinct bodies, b) ensuring the consistent order of people across frames in multi-person perspectives, c) the removal of pose information for the moderator, and d) the anonymisation of utterances containing sensitive information.
 The resulting data is stored in one JSON file per transcript. Each file contains the pose information of the three published camera perspectives. The data format is designed to collect the default single-frame outputs of OpenPose in a single file and to provide additional relevant metadata for each camera perspective.

description: Highly accreting quasars are characterized by distinguishing properties in the 4D eigenvector 1 parameter space that make them easily recognizable over a broad range range of redshift and luminosity. The 4D eigenvector 1 approach allows us to define selection criteria that go beyond the restriction to Narrow Line Seyfert 1s identified at low redshift. These criteria are probably able to isolate sources with a defined physical structure i.e., a geometrically thick, optically thick advection-dominated accretion disk (a "slim" disk). We stress that the importance of highly accreting quasars goes beyond the understanding of the details of their physics: their Eddington ratio is expected to saturate toward values of order unity, making them possible cosmological probes.

description: The growing animal reservoir of antibiotic-resistant Staphylococcus aureus is of public health concern. Industrial livestock operations are a potential source of exposure to these bacteria, which may be transmitted from animals to workers, and then to the community. To increase our understanding of occupational exposures to antibiotic-resistant S. aureus, we assessed nasal carriage of S. aureus, including multidrug-resistant S. aureus (MDRSA) and methicillin-resistant S. aureus (MRSA), among workers and household members from industrial livestock operations, antibiotic-free livestock farms, and meat processing plants in North Carolina. We found a higher prevalence of MDRSA in industrial and processing plant participants compared with antibiotic-free participants, and comparable prevalence of MRSA. S. aureus belonging to clonal complex 398 was also discovered for the first time in North Carolina. This study contributes to the growing discourse regarding the public health consequences of large-scale antibiotic use in animal production in the United States.

description: Active galactic nuclei jets are detected via their radio and/or gamma-ray emissions while the accretion disks are detected by their optical and UV radiation. Observations of the radio and optical luminosities show a strong correlation between the two luminosities. However, part of this correlation is due to the redshift or distances of the sources that enter in calculating the luminosities from the observed fluxes and part of it could be due to the differences in the cosmological evolution of luminosities. Thus, the determination of the intrinsic correlations between the luminosities is not straightforward. It is affected by the observational selection effects and other factors that truncate the data, sometimes in a complex manner (e.g. Antonucci (2011) and Pavildou et al. (2010)). In this paper we describe methods that allow us to determine the evolution of the radio and optical luminosities, and determine the true intrinsic correlation between the two luminosities. We find a much weaker correlation than observed and sub-linear relations between the luminosities. This has a significant implication for jet and accretion disk physics.

description: Web apps are built by using a combination of HTML, CSS, and JavaScript. While building modern web apps, it is common practice to make use of third-party libraries and frameworks, as to improve developers' productivity and code quality. Alongside these benefits, the adoption of such libraries results in the introduction of JavaScript dead code, i.e., code implementing unused functionalities. The costs for downloading and parsing dead code can negatively contribute to the loading time and resource usage of web apps. The goal of our study is two-fold. First, we present Lacuna, an approach for automatically detecting and eliminating JavaScript dead code from web apps. The proposed approach supports both static and dynamic analyses, it is extensible and can be applied to any JavaScript code base, without imposing constraints on the coding style or on the use of specific JavaScript constructs. Secondly, by leveraging Lacuna we conduct an experiment to empirically evaluate the run-time overhead of JavaScript dead code in terms of energy consumption, performance, network usage, and resource usage in the context of mobile web apps. We applied Lacuna four times on 30 mobile web apps independently developed by third-party developers, each time eliminating dead code according to a different optimization level provided by Lacuna. Afterward, each different version of the web app is executed on an Android device, while collecting measures to assess the potential run-time overhead caused by dead code. Experimental results, among others, highlight that the removal of JavaScript dead code has a positive impact on the loading time of mobile web apps, while significantly reducing the number of bytes transferred over the network.

description: We consider the problem of learning mixtures of product distributions over discrete
domains in the distribution learning framework introduced by Kearns et al. [Proceedings of the
26th Annual Symposium on Theory of Computing (STOC), Montr´eal, QC, 1994, ACM, New York,
pp. 273–282]. We give a poly(n/ε)-time algorithm for learning a mixture of k arbitrary product
distributions over the n-dimensional Boolean cube {0, 1}n to accuracy ε, for any constant k. Previous
polynomial-time algorithms could achieve this only for k = 2 product distributions; our result answers
an open question stated independently in [M. Cryan, Learning and Approximation Algorithms for
Problems Motivated by Evolutionary Trees, Ph.D. thesis, University of Warwick, Warwick, UK, 1999]
and [Y. Freund and Y. Mansour, Proceedings of the 12th Annual Conference on Computational
Learning Theory, 1999, pp. 183–192]. We further give evidence that no polynomial-time algorithm
can succeed when k is superconstant, by reduction from a difficult open problem in PAC (probably
approximately correct) learning. Finally, we generalize our poly(n/ε)-time algorithm to learn any
mixture of k = O(1) product distributions over {0, 1, . . . , b − 1}n, for any b = O(1).

description: Does having an incarcerated parent adversely affect the outcomes of children? Using the National Longitudinal Study of Adolescent Health (Add Health), I explore if incarceration of a biological father leads to increased probability of criminal behavior and arrest among adult offspring. Analysis suggests that adult children of incarcerated parents are more likely to engage in criminal behavior and face encounters with the criminal justice system. With 2 million individuals serving time in prison or jail in 2000 and the emergence of incarceration as a life-course event among less-educated males and minorities, intergenerational patterns of crime and incarceration may provide new context to the rapidly expanding prison population and the transmission of social disadvantage from parents to children.

description: We propose a new scenario for the onset of positive acceleration of our Universe based on symmetry breaking in coupled dark energy scalar field model. In a symmetry breaking process where the scalar field rolls down its own potential, the potential reduction is not in favor of acceleration. In our model, when dark matter density becomes less than a critical value, the shape of the effective potential is changed and, the quintessence field climbs up along {\it{its own potential}} while rolls down the effective potential. We show that this procedure may establish the positivity of the potential required for the Universe to accelerate. In addition, we show that by choosing an appropriate interaction between dark sectors there is the possibility that the scalar field resides in a new vacuum giving rise to a positive cosmological constant which is responsible for a permanent late time acceleration.

description: Self-adapting systems based on multiple concurrent applications must decide how to allocate scarce resources to applications and how to set the quality parameters of each application to best satisfy the user. Past work has made those decisions with analytic models that used current resource availability information: they react to recent changes in resource availability as they occur, rather than anticipating future availability. These reactive techniques may model each local decision optimally, but the accumulation of decisions over time nearly always becomes less than optimal. In this paper, we propose an approach to self- adaptation, called anticipatory configuration  that leverages predictions of future resource availability to improve utility for the user over the duration of the task. The approach solves the following technical challenges: (1) how to express resource availability prediction, (2) how to combine prediction from multiple sources, and (3) how to leverage predictions continuously while improving utility to the user. Our experiments show that when certain adaptation operations are costly, anticipatory configuration  provides better utility to the user than reactive configuration, while being comparable in resource demand.

 In dieser Studie werden 17 Faktoren auf ihren Einfluss auf die Selbstwirksamkeit untersucht. Persönli­che Erfolge erweisen sich dabei als massgeblicher Einflussfaktor, bei deren Ausbleiben sich negative Muster abzeichnen. Erfolgshemmend erweisen sich suboptimale individuelle Bedingungen der Kinder, die ihre Erfolgsbemühungen einschränken und sich in ihren Lernschwierigkeiten niederschlagen. Ein grösseres Zeitbudget könnte der Intervention zuträglich sein.
Birth Weight, Birth Length, and Gestational Age as Indicators of Favorable Fetal Growth Conditions in a US Sample

description: The "fetal origins" hypothesis suggests that fetal conditions affect not only birth characteristics such as birth weight and gestational age, but also have lifelong health implications. Despite widespread interest in this hypothesis, few methodological advances have been proposed to improve the measurement of fetal conditions. A Statistics in Medicine paper by Bollen, Noble, and Adair examined favorable fetal growth conditions (FFGC) as a latent variable. Their study of Filipino children from Cebu provided evidence consistent with treating FFGC as a latent variable that mediates the effects of mother's characteristics on birth weight, birth length, and gestational age. Our study assesses whether the FFGC model of Cebu replicates and generalizes to a population of children from North Carolina and Pennsylvania. Using a series of structural equation models, we find that key features of the Cebu analysis replicate and generalize while we also highlight differences between these studies.

description: Context. Many Internet content platforms, such as Spotify and YouTube, provide their services via both native and Web apps. Even though those apps provide similar features to the end user, using their native version or Web counterpart might lead to different levels of energy consumption and performance. Goal. The goal of this study is to empirically assess the energy consumption and performance of native and Web apps in the context of Internet content platforms on Android. Method. We select 10 Internet content platforms across 5 categories. Then, we measure them based on the energy consumption, network traffic volume, CPU load, memory load, and frame time of their native and Web versions; then, we statistically analyze the collected measures and report our results. Results. We confirm that native apps consume significantly less energy than their Web counterparts, with large effect size. Web apps use more CPU and memory, with statistically significant difference and large effect size. Therefore, we conclude that native apps tend to require fewer hardware resources than their corresponding Web versions. The network traffic volume exhibits statistically significant difference in favour of native apps, with small effect size. Our results do not allow us to draw any conclusion in terms of frame time. Conclusions. Based on our results, we advise users to access Internet contents using native apps over Web apps, when possible. Also, the results of this study motivate further research on the optimization of the usage of runtime resources of mobile Web apps and Android browsers.

description: Limited lookahead has been studied for decades in perfect-information games. This paper initiates a new direction via two simultaneous deviation points: generalization to imperfect-information games and a game-theoretic approach. The question of how one should act when facing an opponent whose lookahead is limited is studied along multiple axes: lookahead depth, whether the opponent(s), too, have imperfect information, and how they break ties. We characterize the hardness of finding a Nash equilibrium or an optimal commitment strategy for either player, showing that in some of these variations the problem can be solved in polynomial time while in others it is PPADhard or NP-hard. We proceed to design algorithms for computing optimal commitment strategies for when the opponent breaks ties 1) favorably, 2) according to a fixed rule, or 3) adversarially. The impact of limited lookahead is then investigated experimentally. The limited-lookahead player often obtains the value of the game if she knows the expected values of nodes in the game tree for some equilibrium, but we prove this is not sufficient in general. Finally, we study the impact of noise in those estimates and different lookahead depths. This uncovers a lookahead pathology

description: In der vorliegenden Arbeit wird untersucht, ob mit einem Förderverfahren die Aufmerksamkeit und auch die Schulleistungen von aufmerksamkeitsbeeinträchtigten Kindern in einer dritten Klasse verbessert werden können.
 Auf der Grundlage bekannter Verfahren wird ein kooperatives Trainingsverfahren für die ganze Klasse erstellt, welches theoretisch begründet, praktisch erprobt und evaluiert wird. Die gängigen Interventionen setzen auf die Arbeit in Kleingruppen. In diesem Trainingsverfahren wird der Modellierungsprozess nicht nur von der Lehrperson, sondern zusätzlich vom Lerntandem übernommen, was einen Einsatz im Klassenverband ermöglicht.
 Zur Überprüfung der Wirksamkeit wird die konzentrierte Aufmerksamkeit in der Experimental-gruppe und einer Kontrollgruppe gemessen. Weiter werden qualitative Daten durch Beobachtungen und Interviews erhoben, um Aussagen über die Automatisierung von metakognitiven Strategien machen zu können. Alle Kinder der Experimentalgruppe haben sich in der Aufmerksamkeit und im Beherrschen der metakognitiven Strategien verbessert, allerdings kann die erzielte Verbesserung nicht als statistisch signifikant beschrieben werden.
 Das Trainingsverfahren wird als Produkt zusammengestellt, damit es zukünftig für die Förderung in anderen Klassen genutzt werden kann. Es liegt in Form eines Buches mit Kopiervorlagen vor.
Associations between Infant Behavior during the Face-to-Face Still Face Paradigm and Oppositional Defiant and Callous-Unemotional Behaviors in Early Childhood
Creators: name: Wagner, Nicholas
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Extant research with child and adolescent samples investigating the behavioral correlates of oppositional defiant (ODD) and callous-unemotional (CU) traits have identified deficits in social orienting during dyadic interactions and hyporeactivity to fearful and stressful stimuli. The goal of the current study was to investigate infants' mother-directed gaze and affective behavior during the face-to-face and still-face episodes of the face-to-face still face paradigm performed at 6 months in the prediction of oppositional defiant and callous-unemotional behaviors in early childhood. Hierarchical regression analyses revealed that infants' expressed negative affect and mother-directed gaze predicted fewer ODD behaviors in early childhood. Similarly, infants' expressed negative affect during the still face episode predicted fewer ODD and CU behaviors in early childhood. Further, mother-directed gaze during the free play episode attenuated the negative relationship between negative affect during the still face episode and ODD and, at least marginally, CU behaviors in early childhood.

description: We compare the Hybrid Monte Carlo (HMC) and the Kramers equation algorithms for simulations of QCD with two flavors of dynamical Wilson fermions and gauge group SU(2). The results for the performance of both algorithms are obtained on 6312, 124 and 164 lattices at a pion to ϱ meson mass ratio of mπ/mϱ ∼ 0.9. We find that the Kramers equation algorithm gives an equally good performance as the HMC algorithm. We demonstrate that the classical equations of motion used in these algorithms lack reversibility in practical simulations and behave like those of a chaotic dynamical system with a Liapunov exponent ν ∼ 0.75.

description: We investigate strong normalization, confluence, and behavioral equality in the realm of session-based concurrency. These interrelated issues underpin advanced correctness analysis in models of structured communications. The starting point for our study is an interpretation of linear logic propositions as session types for communicating processes, proposed in prior work. Strong normalization and confluence are established by developing a theory of logical relations. Defined upon a linear type structure, our logical relations remain remarkably similar to those for functional languages. We also introduce a natural notion of observational equivalence for session-typed processes. Strong normalization and confluence come in handy in the associated coinductive reasoning: as applications, we prove that all proof conversions induced by the logic interpretation actually express observational equivalences, and explain how type isomorphismsresulting from linear logic equivalences are realized by coercions between interface types of session-based concurrent systems.

Less is More: Compact Matrix Decomposition for Large Sparse Graphs

description: Given a large sparse graph, how can we find patterns and
anomalies? Several important applications can be modeled
as large sparse graphs, e.g., network traffic monitoring,
research citation network analysis, social network analysis,
and regulatory networks in genes. Low rank decompositions,
such as SVD and CUR, are powerful techniques for revealing
latent/hidden variables and associated patterns from high
dimensional data. However, those methods often ignore the
sparsity property of the graph, and hence usually incur too
high memory and computational cost to be practical.

We propose a novel method, the Compact Matrix Decomposition
(CMD), to compute sparse low rank approximations.
CMD dramatically reduces both the computation
cost and the space requirements over existing decomposition
methods (SVD, CUR). Using CMD as the key building
block, we further propose procedures to efficiently construct
and analyze dynamic graphs from real-time application
data. We provide theoretical guarantee for our methods,
and present results on two real, large datasets, one on network
flow data (100GB trace of 22K hosts over one month)
and one on DBLP (200MB over 25 years).

We show that CMD is often an order of magnitude more
efficient than the state of the art (SVD and CUR): it is over
10X faster, but requires less than 1/10 of the space, for the
same reconstruction accuracy. Finally, we demonstrate how
CMD is used for detecting anomalies and monitoring time-evolving
graphs, in which it successfully detects worm-like
hierarchical scanning patterns in real network data.
Budget Priorities in Hybrid Regimes: Elections and the Effect of Crisis
Creators: name: Garifullina, Guzel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This research project uses public spending to approximate for policy decisions in hybrid regimes. I look at two specific kinds of challenges that may destabilize hybrids - and external economic crisis (in the same way it affects other regimes) and popular elections (which create uncertainty and a dual challenge from masses and elites to the incumbent’s power). Starting from the well-developed research literature on regime survival, I argue that regime stability will depend not only on the severity and nature of challenge to the regime, but also on the response strategy adopted by the incumbent leader. Exploring response strategies through the lens of spending dynamics in the Russian regions in 2001-2014, I build and use a two-dimensional decision space, containing the trade-off between long-term (investment) and short-term (consumption) spending strategies, as well as redistribution between the elites and the mass groups in the short term. I show that the economic crisis is associated with a decrease of spending on supporting the economy and health care (long-term) and an increase of spending on social welfare (short-term). Elections are shown to have a positive effect on spending on the bureaucracy (elite) and a negative effect on mass social welfare programs. That supports the hypotheses that an economic crisis motivates redistribution to immediate needs, and leaders facing elections prefer redistribution to elite groups to ensure their support. Election competitiveness strengthens the latter effect. The proposed theory adds to our understanding of nondemocratic regime functioning and dynamics.

description: High quality (1 1 1)-oriented CoCr$_2$O$_4$/Al$_2$O$_3$ heterostructures were synthesized on the sapphire (0 0 0 1) single crystal substrates in a layer-by-layer mode. The structural properties are demonstrated by $in$-$situ$ reflection high energy electron diffraction, atomic force microscopy, X-ray reflectivity and X-ray diffraction. X-ray photoemission spectroscopy confirms that the films possess the proper chemical stoichiometry. This work offers a pathway to fabricating spinel type artificial quasi-two-dimensional frustrated lattices by means of geometrical engineering.

description: Die Anzahl von Lernenden mit Leseschwierigkeiten ist in den Schulen noch immer hoch. Diese Literaturrecherche geht der Fragestellung nach, wie das Leseverständnis von Schülerinnen und Schülern mit Leseschwierigkeiten über Lesestrategien gefördert werden kann. Dabei wird von einem kombinierten Einsatz von als wirksam erkannten kognitiven und metakognitiven Lesestrategien ausgegangen. Diese sollen auf integrativdidaktischer Grundlage, diagnosegestützt und individuell aufgebaut werden. Die Begleitung metakognitiver Prozesse durch Lesestrategiecoaching sowie dialogische, handelnde und bildhafte Verfahren unterstützt den Zugang zu diesen anspruchsvollen Lernvorgängen. Auf der Basis der in dieser Arbeit beschriebenen Prinzipien werden bedeutsame Unterrichtselemente für die Lesestrategieförderung abgeleitet und der Aufbau eines idealtypischen Förderprogramms mit dem sog. Reflektierenden Leseteam modellhaft skizziert.

description: Um die von der WHO definierten Lebenskompetenzen von Kindern früh zu stärken, lancierte die Suchtprävention Aargau das Projekt «Spielzeugfreier Kindergarten». Anlehnende Präventionskonzepte im Bereich der HFE liegen nicht vor. Hinsichtlich des Präventionsauftrages verbleibt Handlungsbedarf auf praxisorientierter Ebene.
 In dieser Arbeit wird mithilfe eines Fragebogens untersucht, wie ein für die HFE konzipiertes Projekt per Homepage aufbereitet werden kann, um eine autonome Durchführung zu ermöglichen. Die Arbeit baut auf Studien, Konzepten und spieltheoretischem Wissen auf.
 Die Ergebnisse zeigen, dass Hintergrundwissen, Konzeptbeschreibung, Umsetzungsideen sowie Vertiefungsmaterialien in Korrelation zur individuellen Umsetzung stehen. Das Projekt stellt einen vielversprechenden Ansatz im familiären Setting dar, der durch Praxiseinblicke und familienunterstützende Materialien optimiert werden kann.
