description: Research in educational psychology frequently focuses on the role emotions play in learning and on related antecedents and outcomes. However, studies are often limited to a restricted number of subject domains such as mathematics, languages, or science. As civic education differs in relevant aspects from other educational disciplines (e.g., due to its cross-curricular nature and its tendency to incorporate recent political and social developments), there is a need to develop and validate scales focusing on emotions as they specifically relate to this subject. In the proposed study, we develop and validate self-report scales for three instances of civic education in which emotions likely are elicited: a class-related emotions scale, a (cross-curricular) political discussion-related emotions scale, and an epistemic emotions scale focusing on emotions experienced during processing of political information. Additionally, political topic emotions are assessed using single-item emotions scales. The objective is to analyse the internal and external validity of the scales, thereby asking whether the internal structure of discrete emotions can be shown by the data, and measurement invariance is provided. In terms of external validity, the study asks whether discrete emotions are related to antecedents and effects of emotions as proposed by the control-value theory. As antecedents, measures on control- and value-appraisals (e.g., domain specific self-concept, internal political efficacy, personal importance) were adapted to fit to the civic education context. As measures for outcomes of emotions, students' extrinsic and intrinsic motivation, engagement with politics, school grade in civic education, and achievement on a political knowledge quiz are used. All scales will be validated using data (expected N = 500) from students of part-time vocational schools (class-related emotions) and full-time vocational and non-vocational schools of the academic track (discussion-related emotions) at grade 10 to 13 in Austria. Data collection is planned for April to May 2021 using online-questionnaires which are shared with students via schools. Schools are sampled with a stratified random samples, stratified to region and school type. Confirmatory factor analysis will be used to assess the internal validity of the scales. For external validity, bivariate correlation analysis and structural equation models for latent correlations will be used in order to test relationships to antecedents and effects of emotions.

description: The adsorption of retarders on the surface of cement minerals is the main reason for the delayed cement hydration and the prolonged thickening time of oil well cement. This paper studied the adsorption of carboxyl-containing monomers on calcium silicate (C3S) with first-principle calculations based on density functional theory (DFT). The geometric structure was optimized, and the bond length, adsorption energy, charge transfer, charge density difference and partial density of states (PDOS) were calculated. The results indicated that the four carboxyl-containing monomers (acrylic acid, citraconic acid, itaconic acid, and maleic acid) all had strong adsorption energy, and they were ranked in the following order: itaconic acid > maleic acid > citraconic acid > acrylic acid. In addition, the charge density difference and PDOS results proved the strong adsorption. The charge density of the area between the O atom of the carboxyl group and the Ca atom on the C3S (040) surface increased. The overlapping of peaks and the hybridization occurred between Ca 3d and O 2p orbitals. This study deepens the understanding of the retarding mechanism on oil well cement.

description: We study Klein tunneling in polariton graphene. We show that the photonic spin-orbit coupling associated with the energy splitting between TE and TM photonic modes can be described as an emergent gauge field. It suppresses the Klein tunnelling in small energy range close to the Dirac points. Thanks to polariton spin-anisotropic interactions, polarized optical pumping allows to create potential barriers acting on a single polariton spin. We show that the resulting spin-dependent Klein tunneling can be used to create a perfectly transmitting polarization rotator operating at microscopic scale.

description: Background: Patients with chronic pain often complain of memory problems. Previous studies found correlations between chronic pain and deficits of various types of memory (working, semantic, episodic). In particular, it is interesting to focus on patients with chronic low back pain (CLBP), the chronic pain most common in the population. Objectives of this scoping review is: I) investigate what is known from the published literature regarding memory deficits in patients with chronic LBP; II) map the available literature on memory deficits in patients with chronic LBP; III) identify if there are knowledge gaps on this topic; IV) summarize the results based on type of study, type of memory deficit and test used to evaluate. Inclusion Criteria: studies with a population of subjects affected by Chronic Low Back Pain and studies that explore memory disorder will be considered. Any type of published work (no limits based on study design). No date, geographic or language limit have been inserted. Methods: This scoping review will be performed in accordance with Joanna Briggs Institute. MEDLINE, Cochrane Library, PEDro, CINAHL, TRIP, EMBASE Database will be searched; in addition, systematic review protocols on PROSPERO were sought. Two reviewers will independently screen all abstracts and full-text studies for inclusion Conclusion: This will be the first scoping review to provide an overall overview of the topic. The results of this review will help to establish the possible need for other studies related to this purpose.

Shortest Common Supersequence Problem

description: The shortest common supersequence problem (SCSP) is a well-known NP-hard problem with many applications, in particular in data compression, computational molecular biology, and text editing. It aims at finding for a given set of input strings a shortest string such that every string from the set is a subsequence of the computed string. Due to its NP-hardness, many approaches have been proposed to tackle the SCSP heuristically. The currently best-performing one is based on beam search (BS). In this paper, we present a novel heuristic (AEL) for guiding a BS, which approximates the expected length of an SCSP of random strings, and embed the proposed heuristic into a multilevel probabilistic beam search (MPBS). To overcome the arising scalability issue of the guidance heuristic, a cut-off approach is presented that reduces large instances to smaller ones. The proposed approaches are tested on two established sets of benchmark instances. MPBS guided by AEL outperforms the so far leading method on average on a set of real instances. For many instances new best solutions could be obtained.

description: This work presents the results of a multi mode ITER study on Toroidal Alfven Eigenmodes, using the nonlinear hybrid HAGIS-LIGKA model. It is found that main conclusions from earlier studies of ASDEX Upgrade discharges can be transferred to the ITER scenario: global, nonlinear effects are crucial for the evolution of the multi mode scenario. This work focuses on the ITER 15 MA baseline scenario with with a safety factor at the magnetic axis of $q_0 =$ 0.986. The least damped eigenmodes of the system are identified with the gyrokinetic, non-perturbative LIGKA solver, concerning mode structure, frequency and damping. Taking into account all weakly damped modes that can be identified linearly, nonlinear simulations with HAGIS reveal strong multi mode behavior: while in some parameter range, quasi-linear estimates turn out to be reasonable approximations for the nonlinearly relaxed energetic particle profile, under certain conditions low-n TAE branches can be excited. As a consequence, not only grow amplitudes of all modes to (up to orders of magnitude) higher values compared to the single mode cases but also, strong redistribution is triggered in the outer radial area between $ρ_\mathrm{pol} =$ 0.6 and 0.85, far above quasi-linear estimates.

description: Beam search (BS) is a well-known incomplete breadth-first-search variant frequently used to find heuristic solutions to hard combinatorial optimization problems. Its key ingredient is a guidance heuristic that estimates the expected length (cost) to complete a partial solution. While this function is usually developed manually for a specific problem, we propose a more general Learning Beam Search (LBS) that uses a machine learning model for guidance. Learning is performed by utilizing principles of reinforcement learning: LBS generates training data on its own by performing nested BS calls on many representative randomly created problem instances. The general approach is tested on two specific problems, the longest common subsequence problem and the constrained variant thereof. Results on established sets of benchmark instances indicate that the BS with models trained via LBS is highly competitive. On many instances new so far best solutions could be obtained, making the approach a new state-of-the-art method for these problems and documenting the high potential of this general framework.

An Educational Approach for Improving Health Literacy in Patients with Heart Failure
Creators: name: Kennedy, Lauren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: ABSTRACT
      This project sought to modify an existing HF education book, which aimed to improve the quality of HF patient education and increase health literacy levels while achieving lower rates of hospital readmission and acute care utilization in patients with a recent HF admission.  This quality improvement project utilized a quasi-experimental design.  Participants were voluntarily enrolled as inpatients who possessed either new or existing diagnosis of heart failure and were going to follow up in the Advanced Heart Failure Clinic.  Patients arrived for an education session and a pretest/posttest health literacy assessment using the short form of the test of functional health literacy in adults and the newest vital sign prior to their scheduled hospital follow-up visit.
      After the education session, 58% of patients demonstrated an improvement in health literacy levels.  Twenty-five percent of patients scored perfect scores on the health literacy screening tools and could not show an improvement.    The greatest benefit on health literacy levels as measured by the S-TOFHLA was seen in the patient population who were diagnosed within one year of the visit (p=0.0278).  The secondary outcome of 30-day readmission rate for this sample was 8.33%.  This is lower than the hospital average 30-day readmission rate of 20.1%.  Overall, the quality improvement project has shown a positive impact on patient health literacy levels and may indicate an improvement of 30-day
      readmission rates.  A larger sample size will be required to definitively show a positive impact on 30-day readmission rates and acute care utilization rates.

description: In order to improve the key rate of the decoy-state method, we need to jointly study yields of different bases. Given the delicate fact that pulses of the same preparation state can have different counting rates if they are measured in different bases, for example, those vacuum pulses and those single-photon pulses, existing results of decoy-state quantum key distribution using biased bases are actually flawed by assuming that they are equal. We fix this flaw through using the idea that yields of pulses prepared in different bases are same provided that they are prepared in the same state and also they are measured in the same basis, for example, those single-photon pulses prepared in different bases but measured in the same basis. Based on this, we present correct formulas for the decoy-state method using biased bases. Taking the effects of statistical fluctuations into account, we then numerically study the key rates of different protocols with all parameters being fully optimized. Our result confirms the prior art conclusion that decoy-state method using biased bases can have advantage to the symmetric protocol with unbiased bases. We obtain high key rates of our 4-intensity protocol (two in X bases and two in Z bases) without using any vacuum source.

description: The alternating earlywood and latewood growth ring structure has a strong influence on the mechanical performance of Norway spruce. In the current study, tensile tests in the longitudinal and tangential directions were performed on a series of specimens representing one growth ring at varying relative humidities. All tested mechanical parameters, namely modulus of elasticity and ultimate tensile stress, followed the density distribution in the growth ring, with the minimum values in earlywood and the maximum values in latewood. The samples were conditioned at three the relative humidities 50%, 65% and 95%. With increasing relative humidity, the values of the mechanical parameters were found to decrease. However, due to the high local variability, this decrease was not statistically significant. The test in the tangential direction on a set of earlywood and latewood specimens at 65% relative humidity revealed a similar limit of linear elasticity for both early- and latewood. Where the strength of both tissues was equal, the strain at failure was significantly greater for earlywood. Furthermore, the portion of the non-linear stress/strain behavior for earlywood was significantly greater. A Weibull analysis on the ultimate tensile strength revealed a tissue-independent Weibull modulus, which indicates similar defect distributions. For both, the failure occurred in the middle lamella.

description: Nonlinear optical methods, such as coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS), are able to perform label free imaging, with chemical bonds specificity. Here, we demonstrate that the use of circularly polarized light allows to retrieve not only the chemical nature but also the symmetry of the probed sample, in a single shot measurement. Our symmetry-resolved scheme offers simple access to the local organization of vibrational bonds and as a result provides enhanced image contrast for anisotropic samples as well as an improved chemical selectivity. We quantify the local organization of vibrational bonds on crystalline and biological samples, thus providing new information not accessible by spontaneous Raman and SRS techniques. This work stands for a novel symmetry-resolved contrast in vibrational microscopy, with potential application in biological diagnostic.

description: Division I women's volleyball currently harbors two increasing trends. First, there are more and more student-athletes who are committing to their institution more than 24 months before August of their freshman year. Second, the number of student-athletes that transfer each year is steadily increasing. Coaches have already publicly equated the two trends, citing early commitment and the negatives that come with it as hindering their ability to retain high-level athletes. This study, however, analyzed 6,404 Division I volleyball student-athletes who committed between 2005-2010 and found that early commitment is not significantly predictive or influential to be the main cause of student-athlete transfers or drop-offs.

description: Summary form only given. High harmonic generation (HHG) requires high peak-power laser sources. Most of the well-known high peak power lasers are operating in the near-IR wavelength region. Recently it was demonstrated that HHG can be effectively phase matched in the soft X-ray region by using very high intensity UV lasers and multiply charged ions [1]. High average and high peak power UV sources operating around and below 280 nm are required for many other applications, such as ablation in ophthalmology, materials processing and photoelectron spectroscopy. Due to lack of ultrafast high peak power lasers operating in UV, generation of ultrashort UV pulses is possible by up-converting frequency of near-IR laser. This can be done by cascaded harmonic generation in nonlinear crystals with efficiency higher than 40% [2]. However, to obtain high pulse energies in UV region, high energy IR pump is necessary. This becomes increasingly difficult for femtosecond laser pulses because of the optical damage problem in CPA systems. Very high pulse stretching rates in the CPA become unfeasible due to the limited size of dispersive optics. Alternatively, the intensity in the laser cavity can be decreased by using a pulse burst which effectively increases the pulse duration. Therefore, this approach is also suitable for increasing energy throughput in fiber delivery and fiber post compression schemes [3]. © 2017 IEEE

description: This review presents an assessment of international wastewater treatment plant (WWTP) energy benchmarking studies and provides for the first time a detailed historical evolution of seminal European benchmarking methodology for the international water sector. We commence by comparing international applications of energy performance assessment and how the different methods have been applied and have evolved. More specifically, we investigate how international studies have measured WWTP energy performance and what are the different views in relation to energy performance reference value, whether the energy consumption should be related to the number of people connected, the applied load, treated wastewater volume, and the advantages and disadvantages of different approaches. International literature sources were identified using targeted keyword searches using Google Scholar in order to capture a broad range of scholarly and technical works. The review then follows with a detailed account of the origin and development of the seminal (German) energy benchmarking methodologies, delivered here for the first time and opening up previously inaccessible literature to an international audience. The review finds that despite its long-term use, disagreement remains regarding the most suitable energy benchmarking performance metrics and there is currently no internationally agreed approach to assess the energy performance of a WWTP. It further highlights that the European approach to energy benchmarking demonstrates that methodical optimisation of WWTPs and application of identified energy-saving measures, presents great opportunities to deliver achievable, environmentally and economically favourable change to water industry practice. Nevertheless, site-specific factors such as differing discharge conditions, topographical boundary conditions, wastewater volume and composition need to be considered when adapting and applying energy benchmarking methodologies elsewhere, and these factors should be taken into consideration by wastewater practitioners during energy benchmarking assessments.

description: The essay addresses the Platonic concept of space (chora) through the idea of the angel, in light of the philosophical and theological implications that this very idea has unleashed, especially within the great Islamic speculation of Sufism. Displaying itself according to a complex metaphysics of light, the angel does not present itself as a personal entity, but as the mind’s gaze on the world, and simultaneously as the reality, authentic and profound, of the world itself. Though, this contemplating is affirmed as a true purification of the contemplated space. The angel is the sanctification of space itself, and its occurrence coincides with the loss, by space, of all contingency or accidentality. In this sense, the angel is the contemplation of purified space as a region of the ecstatic happening of knowledge.

description: Asteroids are frequently colliding with small projectiles. Although each individual small collision is not very important, their cumulative effect can substantially change topography and also the overall shape of an asteroid. We run simulations of random collisions onto a single target asteroid represented by triaxial ellipsoid. We investigated asteroids of several hundred meters to about 18 km in diameter for which we assumed all material excavated by the collision to escape the asteroid. The cumulative effect of these collisions is an increasing elongation of the asteroid figure. However, the estimated timescale of this process is much longer than the collisional lifetime of asteroids. Therefore, we conclude that small collisions are probably not responsible for the overall shape of small asteroids.

description: According to Hans Blumenberg, Weltbildverlust is the distinctive trait of the Modern Age. World-images are lost and forgotten due to the rise of scientific and operative world-models. This understanding of science reconnects with the ancient project of philosophy: to emancipate knowledge from images—something that the philosophical tradition, from Plato onwards, has always looked with deference and as potentially treacherous. Digital technology seems to fulfil this dream: it turns knowledge into a numeric matter, computable and non-figurative. This is the character of what Jean-François Lyotard named as the postmodern condition. And yet, today we find ourselves drowning in pictures, as portable devices push to an even more capillary diffusion—in space and in time—of the “spectacle” of society. The emancipation of images turns into its opposite: with the digital everything is image. In a computerised society knowledge becomes a matter of production and consumption, handing it into the “treacherous” hands of sophistry which philosophy was trying to preserve it from. At the same time, contemporary physics is confronted with a principal indeterminacy: picturing something can no longer be considered an impartial act and observation (the picturing itself) must be considered as a constitutive part of the equation: if truth, as Walter Benjamin once said, must be intentionslos, intellection cannot. On these bases, the paper will argue for an urgency to reconsider pictures and images and of their constitutive role for an architectonic understanding of science, media, and technology in the so-called Digital Age. In this context, images are not representations of something as much as representatives: they are endowed with a political autonomy—a non-predicative kind of figuration—that makes them an expression of an ontological difference, a ‘writing’ of legibility itself. In this light, knowledge is not anymore the object of epistemology but of architectonics, and intellection is not just a ‘reading’ but Entwurf: an articulation (via images) of a contingent ‘pact’ with the negligible—i.e. with what such reading cannot accommodate.

description: We analyse a non-relativistic approximation of the Dirac equation for slow fermions, coupled to the chameleon field and torsion in the spacetime with the Schwarzschild metric, taken in the weak gravitational field of the Earth approximation. We follow the analysis of the Dirac equation in the curved spacetime with torsion, proposed by Kostelecky (Phys. Rev. D69, 105009 (2004)), and apply the Foldy--Wouthuysen transformations. We derive the effective low-energy gravitational potentials for slow fermions, coupled to the gravitational field of the Earth, the chameleon field and to torsion with minimal and non-minimal couplings.

description: Enterprise Architecture offers guidelines for the coherent, model-based design and management of enterprises. EA models provide a layered, integrated, and cohesive representation of the enterprise, enabling communication, analysis, and decision making. With the increasing size of EA models, automated analysis becomes essential. However, advanced model analysis is neither incorporated in current EA methods like ArchiMate nor supported by existing EA tools like Archi. Knowledge Graphs (KGs) can effectively organize and represent knowledge and enable reasoning to utilize this knowledge, e.g., for decision support. This paper introduces a model-based Enterprise Architecture Knowledge Graph (EAKG) construction method and shows how starting from ArchiMate models, an initially derived EAKG can be further enriched by EA-specific and graph characteristics-based knowledge. The introduced EAKG entails new representation and reasoning methods applicable to EA knowledge. As a proof of concept, we present the results of a first Design Science Research Cycle aiming to realize an Archi plugin for the EAKG that enables analysis of EA Smells within ArchiMate models.
Loop Current and Antiferromagnetic States in Fermionic Hubbard Model with Staggered Flux at Half Filling

description: Anticipating realization of interacting fermions in an optical lattice with a large gauge field, we consider phase transitions and loop currents in a two-dimensional S=1/2 fermionic-Hubbard model with $π$/2-staggered flux at half filling. We use a variational Monte Carlo method, which is reliable even for strong correlations. As a trial wave function, a coexistent state of antifferomagnetic and staggered-flux orders is studied. In a strongly correlated regime, the ground state becomes an insulating coexistent state with loop currents. By comparing fermions with bosons, we discuss an important role of Pauli principle.

Representation and the interests of political minorities
Creators: name: Wilson, Yolonda Yvette
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: It was not uncommon to hear North Carolinians say, Jesse Helms does not represent me. Yet, for thirty years Jesse Helms was a duly elected senator from that state. So, in some sense, he did represent the citizens of North Carolina. How can this be true? How can a representative system of government, working precisely according to the specification of the law, leave a large group of those who are so governed finding themselves to be unrepresented? I use a two-pronged strategy to approach the problem. First, I focus on the aims of representative government and whether being in the minority undermines the goals of representative systems. I argue that it does, and that consequently, we must rethink the morality of representative systems, especially those in which the same people consistently lose. Representative government is a means through which the state can achieve its ends without requiring every citizen to be active in reaching every decision. Citizens have interests, and these interests often compete with one another. So, citizens have (or should have) a stake in who represents them. Second, I focus on political minorities. The mere fact of losing elections is not sufficient warrant for state intervention on behalf of minorities. Building on the work of John Stuart Mill and Lani Guinier, I offer conditions that would need to be satisfied in order to warrant such intervention. If we take seriously the aims of representative government, then we should be deeply concerned about protecting political minorities in societies where the fact of political minority status is fixed, the groups are consistently social and political minorities, and the differences in power between the majority and minorities permeate the society.
The "shook up" galaxy NGC 3079: the complex interplay between HI, activity and environment

description: We present deep neutral hydrogen (HI) observations of the starburst/Seyfert galaxy NGC 3079 and its environment, obtained with the Westerbork Synthesis Radio Telescope. Our observations reveal previously unknown components, both in HI emission and in absorption, that show that NGC 3079 is going through a hectic phase in its evolution. The HI disk appears much more extended than previously observed and is morphologically and kinematically lopsided on all scales with evidence for strong non-circular motions in the central regions. Our data reveal prominent gas streams encircling the entire galaxy suggesting strong interaction with its neighbours. A 33-kpc long HI bridge is detected between NGC 3079 and MCG 9-17-9, likely caused by ram-pressure stripping of MGC 9-17-9 by the halo of hot gas of NGC 3079. The cometary HI tail of the companion NGC 3073, earlier discovered by Irwin et al., extends about twice as long in our data, while a shorter, second tail is also found. This tail is likely caused by ram-pressure stripping by the strong, starburst driven wind coming from NGC 3079. We also detect, in absorption, a nuclear HI outflow extending to velocities well outside what expected for gravitational motion. This is likely an atomic counterpart of the well-studied outflow of ionised gas present in this galaxy. This may indicate that also large amounts of cold gas are blown out of NGC 3079 by the starburst/AGN. Our estimates of the jet energy and kinetic power suggest that both the AGN and the starburst in NGC 3079 are powerful enough to drive the atomic outflow.
