description: The study of dynamics in abstract argumentation gives rise to optimization problems that are NP-hard also under the grounded semantics, in contrast to argument acceptance problems over argumentation frameworks (AF). Developing efficient systems for AF reasoning under grounded semantics has received less attention compared to other central AF semantics under which acceptance is NP-hard. In particular, grounded semantics is not currently supported by recent systems for extension enforcement, despite (or due to) its non-triviality. In this work, we propose and empirically evaluate three first approaches to enforcement under grounded semantics. While each of the approaches is based on employing constraint optimization solvers, we show empirically that there are significant differences in the scalability of the approaches.

description: This project explores whether the potential benefits of the preventive effort against childhood overweight developed by the Spanish autonomous communities (CCAA) are distributed equitably. To do so, it is carried out by means of a multilevel cross-sectional study repeated over time from the information provided by different waves of the National Health Survey (ENS), specifically those of 2003, 2006, 2011 and 2017. Using multilevel logistic regression models, with individuals (level 1) nested in the study period (level 2) and these, in turn, in the autonomous communities (level 3). In order to be able to measure the planning effort made by the Autonomous Communities in policies that can contribute to the prevention of childhood obesity, a synthetic index was constructed from the coding of different plans and programs in the area of healthy eating and physical exercise approved by the autonomous governments in four time periods, namely: prior to 2005, between 2005 and 2009, between 2010 and 2014 and from 2015 onwards. From this index came out the main independent variables the average effort made by the Autonomous Regions in child overweight-obesity prevention policies and the change in the effort made in these policies over the periods studied.

description: Within the context of a 3D interactive strategy game, the EViE platform allows participants to unlock game features using their knowledge and skills in various thematic areas such as physics, mathematics, etc. By answering questions organized by Educational Objective in stratified levels of difficulty, users gather points which grant them access to desired world elements. Richer world components become increasingly more difficult to access, so that a players' individual (or cumulative if in a group) knowledge, ability and / or dexterity is directly reflected by the level of complication of their virtual world. In the present article we report on the communication architecture of the platform and focus on framework components that allow group activities such as cooperation (within the group to facilitate e.g., collaboration on more difficult problems), (inter-group) competition as well as practice and skill honing activities (in single or in multi-player mode).

Longitudinal Multi-Trait-State-Method Model using Ordinal Data
Creators: name: Hutton, Richard Shane
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Multi-trait multi-method (MTMM) models were designed as a way to assess convergent and discriminant validity using multiple traits measured by multiple methods. In recent years, longitudinal extensions of multi-trait multi-method models have been proposed in the structural equation modeling framework to evaluate whether and how the trait as well as method factors change over time. This thesis is intended to propose a longitudinal second-order multi-trait-state-method (M-TSM) model that combines a measurement model for ordinal data, a vector autoregressive moving average (VARMA) model at the latent level to examine changes in the state as well as method factors over time, and a second-order factor analytic model to capture shared trait variances among the state affect factors. A set of affect items from the Affective Dynamics and Individual Differences (Emotions and Dynamic Systems Laboratory, 2010) study was used to illustrate the proposed longitudinal M-TSM model. This study features affect items asked in both a lab and a diary setting. Results of the final model showed that the method factors, lab and diary, had perfect stability across time. Furthermore, factor loadings within the lab factor showed a systemic pattern of positive and negative loadings illustrating the complexity of individuals' affective responses to stimuli in the lab setting. Contrary to conventional theories on emotions, the covariances between positive and negative affect factors at the state level were not significantly different from zero; however, evaluation of higher-order shared covariance between the affect factors across method settings indicates a negative association between the two at the trait level. Comparisons of the auto- and cross-regression regression parameters associated with the state affect factors indicated some key differences in how people regulated negative emotions in a lab versus in a diary setting. Methodological issues associated with fitting the M-TSM model are discussed.
Constructive approaches to Program Induction
Creators: name: Patsantzis, Stassa
Publisher: name: Imperial College London
Year: 2022

description: Search is a key technique in artificial intelligence, machine learning and Program Induction. No matter how efficient a search procedure, there exist spaces that are too large to search effectively and they include the search space of programs. In this dissertation we show that in the context of logic-program induction (Inductive Logic Programming, or ILP) it is not necessary to search for a correct program, because if one exists, there also exists a unique object that is the most general correct program, and that can be constructed directly, without a search, in polynomial time and from a polynomial number of examples. The existence of this unique object, that we term the Top Program because of its maximal generality, does not so much solve the problem of searching a large program search space, as it completely sidesteps it, thus improving the efficiency of the learning task by orders of magnitude commensurate with the complexity of a program space search. The existence of a unique Top Program and the ability to construct it given finite resources relies on the imposition, on the language of hypotheses, from which programs are constructed, of a strong inductive bias with relevance to the learning task. In common practice, in machine learning, Program Induction and ILP, such relevant inductive bias is selected, or created, manually, by the human user of a learning system, with intuition or knowledge of the problem domain, and in the form of various kinds of program templates. In this dissertation we show that by abandoning the reliance on such extra-logical devices as program templates, and instead defining inductive bias exclusively as First- and Higher-Order Logic formulae, it is possible to learn inductive bias itself from examples, automatically, and efficiently, by Higher-Order Top Program construction. In Chapter 4 we describe the Top Program in the context of the Meta-Interpretive Learning approach to ILP (MIL) and describe an algorithm for its construction, the Top Program Construction algorithm (TPC). We prove the efficiency and accuracy of TPC and describe its implementation in a new MIL system called Louise. We support theoretical results with experiments comparing Louise to the state-of-the-art, search-based MIL system, Metagol, and find that Louise improves Metagol’s efficiency and accuracy. In Chapter 5 we re-frame MIL as specialisation of metarules, Second-Order clauses used as inductive bias in MIL, and prove that problem-specific metarules can be derived by specialisation of maximally general metarules, by MIL. We describe a sub-system of Louise, called TOIL, that learns new metarules by MIL and demonstrate empirically that the metarules learned by TOIL match those selected manually, while maintaining the accuracy and efficiency of learning. i

description: Recent measurements of top-quark production at hadron colliders are reviewed. The inclusive top-quark pair production is determined at four centre-of-mass energies at Tevatron and LHC with experimental uncertainties that are close to the uncertainties in theoretical calculations at next-to-next-to-leading order in QCD. Several differential measurements are performed and compared to simulation. Production of single top quarks is studied in the three different production channels. Top-quark pair production with neutral and charged vector bosons has been observed by the LHC experiments. Finally, production of additional heavy flavour quark pairs ($b\bar{b}$, $t\bar{t}$) is studied or searched for.

description: [abbreviated] We present a census of Lyα emission at $z\gtrsim7$ utilizing deep near infrared HST grism spectroscopy from the first six completed clusters of the Grism Lens-Amplified Survey from Space (GLASS). In 24/159 photometrically selected galaxies we detect emission lines consistent with Lyα in the GLASS spectra. Based on the distribution of signal-to-noise ratios and on simulations we expect the completeness and the purity of the sample to be 40-100% and 60-90%, respectively. For the objects without detected emission lines we show that the observed (not corrected for lensing magnification) 1$σ$ flux limits reaches $5\times10^{-18}$erg/s/cm$^{2}$ per position angle over the full wavelength range of GLASS (0.8-1.7$μ$m). Based on the conditional probability of Lyα emission measured from the ground at $z\sim7$ we would have expected 12-18 Lyα emitters. This is consistent with the number of detections, within the uncertainties, confirming the drop in Lyα emission with respect to $z\sim6$. These candidates include a promising source at $z=8.1$. The spatial extent of Lyα in a deep stack of the most convincing Lyα emitters with $\langle z\rangle=7.2$ is consistent with that of the rest-frame UV continuum. Extended Ly$α$ emission, if present, has a surface brightness below our detection limit, consistent with the properties of lower redshift comparison samples. From the stack we estimate upper limits on rest-frame UV emission line ratios and find $f_\textrm{CIV} / f_\textrm{Ly$α$} \lesssim 0.32$ and $f_\textrm{CIII]} / f_\textrm{Ly$α$} \lesssim 0.23$ in good agreement with other values published in the literature.

description: We consider a Haag-Kastler net in a positive energy representation, admitting massive Wigner particles and asymptotic fields of massless bosons. We show that states of the massive particles are always vacua of the massless asymptotic fields. Our argument is based on the Mean Ergodic Theorem in a certain extended Hilbert space. As an application of this result we construct the outgoing isometric wave operator for Compton scattering in QED in a class of representations recently proposed by Buchholz and Roberts. In the course of this analysis we use our new technique to further simplify scattering theory of massless bosons in the vacuum sector. A general discussion of the status of the infrared problem in the setting of Buchholz and Roberts is given.

Instructional Coaching and Co-teaching in Elementary Math Classrooms

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Educational leaders often search for professional development opportunities that are within the context of the classroom where new research-based instructional practices can be observed and incorporated into the teachers’ practices.  Instructional coaching and co-teaching have been recognized as means for accomplishing this, while at the same time increasing collaboration between educators and improving student learning. Very little research has been done on where these two concepts intersect, especially as it is implemented in elementary math classrooms. Using a socio-cultural lens and the Lave and Wenger (1991) LPP (Legitimate Peripheral Participation) framework, the co-teaching relationship that is developed over time between instructional coaches and classroom teachers affect the experiences that result from co-teaching for both of them as they observe one another and interact within the environment. In this holistic multiple case study of five elementary schools in a rural school district, the cross-case analysis indicated that co-teaching facilitated: (1) collaboration between the educators to impact student achievement, (2) learning experiences for the instructional coaches and the teachers, and (3) an impact on student learning. Although partnerships grew and strengthened with more trust between the instructional coaches and the classroom teachers, the primary issues included: (1) a lack of planning time, (2) concerns over the co-teaching schedule, and (3) the logistics of making co-teaching work in the classroom. Issues were broadly resolved through communication, collaboration, and cooperation between the instructional coaches and the teachers who co-taught with them.

description: A $k$-colouring (not necessarily proper) of vertices of a graph is called {\it acyclic}, if for every pair of distinct colours $i$ and $j$ the subgraph induced by the edges whose endpoints have colours $i$ and $j$ is acyclic. In the paper we consider some generalised acyclic $k$-colourings, namely, we require that each colour class induces an acyclic or bounded degree graph. Mainly we focus on graphs with maximum degree 5. We prove that any such graph has an acyclic $5$-colouring such that each colour class induces an acyclic graph with maximum degree at most 4. We prove that the problem of deciding whether a graph $G$ has an acyclic 2-colouring in which each colour class induces a graph with maximum degree at most 3 is NP-complete, even for graphs with maximum degree 5. We also give a linear-time algorithm for an acyclic $t$-improper colouring of any graph with maximum degree $d$ assuming that the number of colors is large enough.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: As a result of the growing business within college athletics, athletic departments have resorted to utilizing search firms to assist in the hiring process of athletic directors. The purpose of this study is to examine whether athletic departments that utilized a search firm in their athletic director hires significantly differ in performance measures compared to those athletic departments who did not use a search firm.
      Athletic directors hired between 2008 and 2015 were analyzed. Background information for each athletic director was collected, as well as whether each athletic director was hired with the aid of a search firm or not. For each athletic director, academic, athletic, and financial data was collected for the corresponding athletic department. Of the athletic directors hired during the given period, 57% included search firm assistance. Statistical t-tests revealed no significant difference of percent change when analyzing two-year pre and post hire performance measures. Three-year post hire means also showed no statistical difference in performance measures of search firm usage. The multi-level models also indicated that over time, there was no significance of search firm use in athletic director hires as it related to the three different performances measured. Implications for practitioners are discussed in the following study.

description: Current industrial trends require flexible and reconfigurable manufacturing systems, with Cyber-Physical Production Systems (CPPS) playing a crucial role. However, the increased flexibility and decentralisation increase the risk of unexpected or emerging system behaviour. Message sequence charts (MSCs) have proven helpful in the early stages of system design to capture intended scenarios. This paper introduces a process that utilises MSCs to identify unexpected system behaviour. After synthesising the MSCs into finite state machines, the process suggests applying Kronecker algebra to verify intended and identify unintended scenarios. The process is illustrated by an example depicting an auto-lock mechanism. The paper concludes by outlining further research focusing on implementing the process and identifying emergence at runtime.

description: We present the first estimate of age, stellar metallicity and chemical abundance ratios, for an individual early-type galaxy at high-redshift (z = 1.426) in the COSMOS field. Our analysis is based on observations obtained with the X-Shooter instrument at the VLT, which cover the visual and near infrared spectrum at high (R >5000) spectral resolution. We measure the values of several spectral absorptions tracing chemical species, in particular Magnesium and Iron, besides determining the age-sensitive D4000 break. We compare the measured indices to stellar population models, finding good agreement. We find that our target is an old (t > 3 Gyr), high-metallicity ([Z/H] > 0.5) galaxy which formed its stars at z_{form} > 5 within a short time scale ~0.1 Gyr, as testified by the strong [α/Fe] ratio ( > 0.4), and has passively evolved in the first > 3-4 Gyr of its life. We have verified that this result is robust against the choice and number of fitted spectral features, and stellar population model. The result of an old age and high-metallicity has important implications for galaxy formation and evolution confirming an early and rapid formation of the most massive galaxies in the Universe.

description: We have studied the superlattices with alternating block layers (BLs) of heavy-fermion superconductor CeCoIn5 and conventional-metal YbCoIn5 by site-selective nuclear magnetic resonance(NMR) spectroscopy, which uniquely offers spatially-resolved dynamical magnetic information. We find that the presence of antiferromagnetic fluctuations is confined to the Ce-BLs, indicating that magnetic degrees of freedom of f-electrons are quenched inside the Yb-BLs. Contrary to simple expectations that the two-dimensionalization enhances fluctuations, we observe that antiferromagnetic fluctuations are rapidly suppressed with decreasing Ce-BL thickness. Moreover, the suppression is more prominent near the interfaces between the BLs. These results imply significant effects of local inversion-symmetry breaking at the interfaces.

Bei der Untersuchung der YouTube-Kanäle greift die Arbeit auf die Webformat-Analyse von Schuegraf und Janssen (2017), die qualitative Inhaltsanalyse nach Mayring und Fenzl (2019) sowie das Analyseraster für Erklärvideokanäle auf YouTube (AEY) (Heiland et al. 2020) zurück, die in Kombination eine systematische Analyse der Kanäle und deren Inhalte ermöglichen. Die Analyse begegnet dem Umstand, dass bislang keine dezidierte Untersuchung der Struktur und der Inhalte bibliothekarischer Aktivitäten auf YouTube existiert. Die Analyse von drei YouTube-Kanälen wissenschaftlicher Bibliotheken zeigt, dass Bibliotheken die Plattform nutzen, um unterschiedlichste Informationen wie Hinweise zu zentralen Services der Einrichtung, zur Orientierung in der Bibliothek oder zum wissenschaftlichen Arbeiten für ihre Nutzer bereitzustellen. Feststellbar ist eine Professionalisierung der YouTube-Auftritte mit Beginn der Coronapandemie. Gleichzeitig zeigt die Analyse auf, dass Bibliotheken die Potentiale, die die Videoplattform YouTube bietet, noch nicht vollständig ausschöpfen.

description: This paper considers the phase retrieval problem in which measurements consist of only the magnitude of several linear measurements of the unknown, e.g., spectral components of a time sequence. We develop low-complexity algorithms with superior performance based on the majorization-minimization (MM) framework. The proposed algorithms are referred to as PRIME: Phase Retrieval vIa the Majorization-minimization techniquE. They are preferred to existing benchmark methods since at each iteration a simple surrogate problem is solved with a closed-form solution that monotonically decreases the original objective function. In total, four algorithms are proposed using different majorization-minimization techniques. Experimental results validate that our algorithms outperform existing methods in terms of successful recovery and mean square error under various settings.

description: V745 Sco is a recurrent nova, with the most recent eruption occurring in February 2014. V745 Sco was first observed by Swift a mere 3.7 hr after the announcement of the optical discovery, with the super-soft X-ray emission being detected around four days later and lasting for only ~two days, making it both the fastest follow-up of a nova by Swift and the earliest switch-on of super-soft emission yet detected. Such an early switch-on time suggests a combination of a very high velocity outflow and low ejected mass and, together with the high effective temperature reached by the super-soft emission, a high mass white dwarf (>1.3 M_sun). The X-ray spectral evolution was followed from an early epoch where shocked emission was evident, through the entirety of the super-soft phase, showing evolving column density, emission lines, absorption edges and thermal continuum temperature. UV grism data were also obtained throughout the super-soft interval, with the spectra showing mainly emission lines from lower ionization transitions and the Balmer continuum in emission. V745 Sco is compared with both V2491 Cyg (another nova with a very short super-soft phase) and M31N 2008-12a (the most rapidly recurring nova yet discovered). The longer recurrence time compared to M31N 2008-12a could be due to a lower mass accretion rate, although inclination of the system may also play a part. Nova V745 Sco (2014) revealed the fastest evolving super-soft source phase yet discovered, providing a detailed and informative dataset for study.

description: We report on the discovery of an eclipsing dwarf nova (DN) inside the peculiar, bilobed nebula Te 11. Modelling of high-speed photometry of the eclipse finds the accreting white dwarf to have a mass 1.18 M$_\odot$ and temperature 13 kK. The donor spectral type of M2.5 results in a distance of 330 pc, colocated with Barnard's loop at the edge of the Orion-Eridanus superbubble. The perplexing morphology and observed bow shock of the slowly-expanding nebula may be explained by strong interactions with the dense interstellar medium in this region. We match the DN to the historic nova of 483 CE in Orion and postulate that the nebula is the remnant of this eruption. This connection supports the millennia time scale of the post-nova transition from high to low mass-transfer rates. Te 11 constitutes an important benchmark system for CV and nova studies as the only eclipsing binary out of just three DNe with nova shells.

description: Secrecy issues of free-space optical links realizing information theoretically secure communications as well as high transmission rates are discussed. We numerically study secrecy communication rates of optical wiretap channel based on on-off keying modulation under typical conditions met in satellite-ground links. It is shown that under reasonable degraded conditions on a wiretapper, information theoretically secure communications should be possible in a much wider distance range than a range limit of quantum key distribution, enabling secure optical links between geostationary earth orbit satellites and ground stations with currently available technologies. We also provide the upper bounds on the decoding error probability and the leaked information to estimate a necessary code length for given required levels of performances. This result ensures that a reasonable length wiretap channel code for our proposed scheme must exist.

description: Cross-chain interoperability is becoming more critical as additional blockchains are added to the Internet of Blockchains. Assets are no longer bound to a specific blockchain but flow across different blockchains, often by making use of decentral- ized exchange services. However, the interoperability of blockchains also poses a system risk, as failures or issues in one blockchain can have ripple effects on other blockchains as well. In decentralized finance and cross-chain interoperability, the Terra Network is a blockchain that has received significant attention from both institutional and individ- ual investors. The Terra Network’s ability to communicate with other blockchains via a number of protocols and cross-chain bridges was a key selling point. This thesis investigates the Terra network in depth, both before and during its col- lapse, looking at its on-chain activity between smart contracts and user accounts and its cross-chain transactions using some of the most popular cross-chain technologies. The first research question was about which assets were used in cross-chain asset transfers between Terra and other blockchains connected through the decentralized exchange Thorchain. The main asset was BUSD on the Binance blockchain, followed by BTC and ETH. The second research question was about the flow of assets between accounts and smart contracts within Terra before and during the collapse. The analy- sis shows that Nexus and Anchor Protocol were the dominant smart contracts with a severe outflow during the collapse. The last research question was about analysing how decentralized Terra, Thorchain and the inter-blockchain communication between Terra and the Cosmos Ecosystem are. It was shown that several centralization issues are present, especially amongst computation services, validator locations and IBC relayers. The implications of the thesis are, that asset flow through the analysed cross-chain technologies is visible and can be tracked, as one would expect from on-chain data as well. Centralization is an issue on various levels of analysis with most analysed blockchains and technologies. Validators are heavily centralized by location and computation services used.

description: Proximity effect in a mechanically exfoliated Bi1.95Sb0.05Se3 topological insulator (TI) single crystal partially covered with disordered superconducting (SC) Mo thin film is reported. Magnetotransport measurement was performed simultaneously across three different regions of the sample viz. SC, TI and SC/TI junction. Resistance measured across SC shows a TC at 4.3 K concomitantly the resistance measurement on TI showed a metallic trend with a steep upturn at TC. Magneto-resistance (MR) measurement on TI exhibit a positive MR with Shubnikov-de Haas (SdH) oscillations, whereas on SC a positive MR superimposed with steep cusp close to TC is observed. Across SC/TI junction both SdH oscillation and the cusp were observed. The frequency of SdH oscillation on SC/TI junction is found to be lesser (~ 125 T) as compared to a reference Bi1.95Sb0.05Se3sample (~ 174 T). Upper critical field HC2 deduced from WHH fit was found to be 17.14 T for a reference Mo film whereas Mo film deposited on TI showed a decreased HC2 of 4.05 T. The coherence length for the former was found to be 4.38 nm and for the latter 9.01 nm. The interaction between the spin-less Cooper pairs in SC with the spin-momentum locked carriers on the surface of TI is believed to cause such changes in transport properties.

On Impersonal Constructions: Implications of Celtic Verbal Inflections
Creators: name: Slavic, Jessica

description: Celtic languages, specifically Irish and Breton, possess a verbal inflection known as "autonomous" or "impersonal." This thesis defines impersonalization as a phenomenon that de-emphasizes the logical subject of a verb. Common forms of impersonalization under this definition include generic pronouns, passivization, and passive with expletive subject constructions. I hold that impersonal verbal inflections should be recognized as a comparable strategy for impersonalization. I recognize the inherent similarity that impersonal verbal inflections bear to passivization in this respect, but I maintain that impersonalization is a distinct syntactic category. All forms of impersonalization should be viewed as members of one broad category possessing heterogeneous syntactic strategies, which are unique and valid methods of de-emphasizing the logical subject. I show that there can be further variation within each strategy, and I give particular attention to the variation in theta role placement in Celtic impersonal forms. This thesis aims to establish the Celtic impersonal inflections as a form of impersonalization comparable to passivization or generic pronouns, and to provide a detailed description of these verbal inflections.

description: The role of $β$ decay as a low-energy probe of physics beyond the Standard Model is reviewed. Traditional searches for deviations from the Standard Model structure of the weak interaction in $β$ decay are discussed in the light of constraints from the LHC and the neutrino mass. Limits on the violation of time-reversal symmetry in $β$ decay are compared to the strong constraints from electric dipole moments. Novel searches for Lorentz symmetry breaking in the weak interaction in $β$ decay are also included, where we discuss the unique sensitivity of $β$ decay to test Lorentz invariance. We end with a roadmap for future $β$-decay experiments.

description: The mechanical behavior of wood products highly depends on structural features on several length scales. This leads to a high amount of random fluctuation in mechanical properties at the structural level. In practice, homogeneous material behavior within timber elements is assumed and uncertainties in loading and load-bearing capacity are considered by using partial safety factors. Those are not directly linked to the mechanical behavior of the considered elements. Therefore, a stochastic framework opening up the possibility to establish such links by combining structural analysis and probabilistic descriptions of wood could be an important step in timber design. For example, in GLT beams the mechanical behavior mostly depends on the tensile properties of individual boards. To describe their fluctuations, simulations on this level are performed. The reconstruction of knots and the implementation of new fracture mechanical methods allows the prediction of stiffness and strength properties for knot sections. Condensation of those results into stiffness and strength profiles permits the development of probabilistic models and the random generation of such profiles, and their use in wood product simulations. This can be used for sensitivity analyses of timber engineering designs or to obtain probabilistic descriptions of the uncertainties at the level of timber elements.

description: A number of observational and theoretical aspects of solar magnetoconvection are considered in this review. We discuss recent developments in our understanding of the small-scale structure of the magnetic field on the solar surface and its interaction with convective flows, which is at the centre of current research. Topics range from plage areas in active regions over the magnetic network shaped by supergranulation to the ubiquituous `turbulent' internetwork fields. On the theoretical side, we focus upon magnetic field generation by small-scale dynamo action.
