The effects of constructive television news reporting on prosocial intentions and behavior in children: The role of negative emotions and self-efficacy
Authors: van Venrooij Iris , Sachs Tobias , Kleemans Mariska 
Published: May 2021

Abstract
To reduce negative emotional responses and to stimulate prosociality, constructive journalism promotes the inclusion of positive emotions and solutions in news. This study experimentally tested whether including those elements indeed increased prosocial intentions and behavior among children, and whether negative emotions and self-efficacy are mediators in this regard. To this end, children (N = 468; 9 to 13 years old) were exposed to an emotion-based, solution-based, or non-constructive news video. Results showed that emotion-based and solution-based news reduced children’s negative emotions compared to non-constructive news. No direct effects for prosocial intentions were found, but solution-based news led to less prosocial behavior (i. e., money donated) than emotion-based and non-constructive news. Moreover, negative emotions served as a mediator, self-efficacy did not. The more negative emotions were elicited by a news story, the higher the prosocial intentions and behavior. In conclusion, a constructive style of reporting helps to reduce children’s negative emotional responses but subsequently hinders prosociality.
Chemically modified glycosaminoglycan derivatives as building blocks for biomaterial coatings and hydrogels
Authors: Schnabelrauch Matthias , Schiller Jürgen , Möller Stephanie , Scharnweber Dieter , Hintze Vera 
Published: May 2021

Abstract
Tissue regeneration is regulated by the cellular microenvironment, e.g. the extracellular matrix. Here, sulfated glycosaminoglycans (GAG), are of vital importance interacting with mediator proteins and influencing their biological activity. Hence, they are promising candidates for controlling tissue regeneration. This review addresses recent achievements regarding chemically modified GAG as well as collagen/GAG-based coatings and hydrogels including (i) chemical functionalization strategies for native GAG, (ii) GAG-based biomaterial strategies for controlling cellular responses, (iii) (bio)chemical methods for characterization and iv) protein interaction profiles and attained tissue regeneration in vitro and in vivo. The potential of GAG for bioinspired, functional biomaterials is highlighted.
Viral Theatre: Preliminary Thoughts on the Impact of the COVID-19 Pandemic on Online Theatre
Authors: Liedke Heidi , Pietrzak-Franger Monika 
Published: May 2021

Abstract
Theatre has been associated with contagion and contagious emotions since Plato and Aristotle. In the twentieth century, Antonin Artaud proposed that theatre or performance should be like the plague that takes control of actors’ and spectators’ bodies and infects them with an affective energy. For these infections to happen, however, audiences and actors must be in the same room. In times of the corona pandemic, this spatial proximity has been substituted by theatre mostly performed and/or streamed online. This article offers some preliminary thoughts on this development: it considers what we descriptively call “viral theatre.” We argue that we currently witness a form of viral theatre that manifests itself through an interplay of three aspects: first, the fact that both performers and spectators are in a state of disruption, second, the willingness/expectations on the part of spectators to participate in the event, and, finally, the use of communication technologies such as Zoom. The framework of the pandemic, therefore, enhances and modifies what viral theatre can be and what kind of effect it can have, oscillating between more Platonic notions of dangerous contagion when plays force us to explore questions of complicity and the Aristotelian ideal of cathartic emotions when plays/performers reach out to us for moral support.
Data curation to improve the pattern recognition performance of B-cell epitope prediction by support vector machine

Published: May 2021

Abstract
B-cell epitope will be recognized and attached to the surface of receptors in B-lymphocytes to trigger immune response, thus are the vital elements in the field of epitope-based vaccine design, antibody production and therapeutic development. However, the experimental approaches in mapping epitopes are time consuming and costly. Computational prediction could offer an unbiased preliminary selection to reduce the number of epitopes for experimental validation. The deposited B-cell epitopes in the databases are those with experimentally determined positive/negative peptides and some are ambiguous resulted from different experimental methods. Prior to the development of B-cell epitope prediction module, the available dataset need to be handled with care. In this work, we first pre-processed the B-cell epitope dataset prior to B-cell epitopes prediction based on pattern recognition using support vector machine (SVM). By using only the absolute epitopes and non-epitopes, the datasets were classified into five categories of pathogen and worked on the 6-mers peptide sequences. The pre-processing of the datasets have improved the B-cell epitope prediction performance up to 99.1 % accuracy and showed significant improvement in cross validation results. It could be useful when incorporated with physicochemical propensity ranking in the future for the development of B-cell epitope prediction module.
The chaîne opératoire of Korenovo pottery: hybrid ceramics? Analysis of mixed Starčevo and Korenovo ceramic assemblages from Kapelica-Solarevac and Kaniška Iva (Central Croatia)
Authors: Spataro Michela , Težak-Gregl Tihomila , Burić Marcel 
Published: May 2021

Abstract
The chaîne opératoire of Neolithic Korenovo ceramics is poorly known, as hitherto potsherds from only three sites, Malo Korenovo, Tomašica in central Croatia, and Becsehely–Bukkaljai dűlő in Hungary have been analysed archaeometrically. Korenovo is considered the southernmost aspect of the Linearbandkeramik (LBK). In this paper, the ceramic assemblage from Kapelica-Solarevac and Kaniška Iva (Central Croatia) will be discussed. Kapelica-Solarevac and Kaniška Iva are the only two sites in which Starčevo and Korenovo ceramics have been found together in closed contexts. Twenty potsherds from the Kapelica-Solarevac and Kaniška Iva assemblages were analysed using polarised microscopy and scanning electron microscopy with energy dispersive spectrometry (SEM-EDX). In combination with equivalent data from 49 Korenovo ceramics from Tomašica and Malo Korenovo, the results offer an insight into the practices of Korenovo potters and show the lack of exchange of technological knowledge between Korenovo and LBK potters in Austria and central Transdanubia (Hungary). On the other hand, Korenovo potters seem to closely follow ceramic recipes typical of the neighbouring Vinča potters, suggesting Korenovo to be a hybrid group between the Vinča and the LBK pottery communities.

Authors: Mírová Zuzana , Fojtík Pavel 
Published: May 2021

Abstract
The article presents a hoard from the Final Bronze Age found in 2005 in the cadastre of Dolany-Nové Sady ‒ “Sádek”, Olomouc District (CZ). It consists of 2 bronze axes, 3 bronze cheek-pieces of a horse’s bit, 2 bronze phalerae, decorated bronze belt sheet, 6 fragments of 3 different plano-convex ingots and a ceramic vessel. The paper deals with the chronological-typological evaluation of the hoard and especially the motivations for its deposition in connection with supra-regional long-distance roads. Authors discuss the model of social organization of the landscape in the Low Jeseník Mountains area and selected adjacent regions.
Advances in seawater membrane distillation (SWMD) towards stand-alone zero liquid discharge (ZLD) desalination

Published: May 2021

Abstract
Seawater membrane distillation (SWMD) is a promising separation technology due to its ability to operate as a stand-alone desalination unit operation. This paper reviews approaches to improve laboratory-to-pilot-scale MD performance, which comprise operational strategies, module design, and specifically tailored membranes. A detailed comparison of SWMD and sea water reverse osmosis is presented to further analyze the critical shortcomings of SWMD. The unique features of SWMD, namely the ability to operate with extremely high salt rejection and at extreme feed concentration, highlight the SWMD potential to be operated under zero liquid discharge (ZLD) conditions, which results in the production of high-purity water and simultaneous salt recovery, as well as the elimination of the brine disposal cost. However, technical challenges, such as thermal energy requirements, inefficient heat transfer and integration, low water recovery factors, and lack of studies on real-case valuable-salt recovery, are impeding the commercialization of ZLD SWMD. This review highlights the possibility of applying selected strategies to push forward ZLD SWMD commercialization. Suggestions are projected to include intermittent removal of valuable salts, in-depth study on the robustness of novel membranes, module and configuration, utilization of a low-cost heat exchanger, and capital cost reduction in a renewable-energy-integrated SWMD plant.
Mobile Telephony in Emerging Markets: The Importance of Dual-SIM Phones
Authors: Andersson Kjetil , Göller Daniel 
Published: May 2021

Abstract
A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected on-net prices. Thus, somewhat paradoxically, deployment of a technology that increases substitutability, and thereby competition, may end up raising prices.
Risk of infection within 4 weeks of corticosteroid injection (CSI) in the management of chronic pain during a pandemic: a cohort study in 216 patients

Published: May 2021

Abstract

Objectives
Targeted corticosteroid injections (CSI) are one of the treatments that can provide pain relief and thereby, enhance quality of life in patients with chronic pain. Corticosteroids (CS) are known to impair immune response. The objective was to evaluate the risk of developing post-procedural infection within 4 weeks of receiving depot CSI for chronic pain as part of on going quality improvement project. We hypothesised that interventional treatment with depot steroids will not cause a significant increase in clinical infection in the first 4 weeks.

Methods
Telephone follow-up was performed as a part of prospective longitudinal audit in a cohort of patients who received interventional treatment for chronic pain at a multidisciplinary pain medicine centre based at a university teaching hospital. Patients who received interventional treatment in the management of chronic pain under a single physician between October 2019 and December 2020 were followed up over telephone as part of on going longitudinal audits. Data was collected on any infection within 4 and 12 weeks of receiving the intervention. Outcomes collected included type of intervention, dose of depot steroids and pain relief obtained at 12 weeks following intervention.

Results
Over a 15 month period, 261 patients received pain interventions with depot CS. There was no loss to follow-up. Nine patients reported an infection within 4 weeks of receiving depot steroids (9/261, 3.4%). None of the patients tested positive for Covid-19. Eight patients (8/261, 3%) reported an infection between 5 and 12 weeks following the corticosteroid intervention. Although none of the patients tested positive for Covid-19, two patients presented with clinical and radiological features suggestive of Covid-19. Durable analgesia was reported by 51% (133/261) and clinically significant analgesia by 30% (78/261) at 12 weeks following the intervention. Failure rate was 19% (50/261).

Conclusions
Pain medicine interventions with depot steroids do not appear to overtly increase the risk for Covid-19 infection in the midst of a pandemic.
Politisierung von Kultur, Religion, und Geschlecht: Die Kulturalisierungen eines verweigerten Handschlags in Deutschschweizer Medien
Authors: Aeschbach Mirjam 
Published: May 2021

ZusammenfassungIn der Deutschschweizer massenmedialen Debatte zur Weigerung zweier Schüler in der Gemeinde Therwil, ihrer Lehrerin die Hand zu schütteln, wird häufig der Kulturbegriff verwendet. Der vorliegende Beitrag analysiert, wie „Kultur“ als wissensstrukturierende Kategorie in der Konstituierung der Gruppenzugehörigkeiten zur Schweizer Mehrheitsgesellschaft und zur muslimischen Minderheit zum Tragen gekommen ist. Basierend auf dem Konzept der „Kulturalisierung“ untersucht die qualitative Medienanalyse die verschiedenen „Spielarten der Kulturalisierung“ (Teczan 2011), die in der Debatte um den Fall Therwil verwendet wurden. Die Ergebnisse zeigen, dass „Kultur“ in Beziehung zu geografischer Herkunft, religiöser Zugehörigkeit und spezifischen Wertvorstellungen gesetzt wurde. Gleichzeitig kann die Verknüpfung dieser Ideen mit Vorstellungen „kulturspezifischer“ Geschlechterverhältnisse und angenommenen Einstellungen zur Geschlechtergerechtigkeit und sexuellen Liberalisierung beobachtet werden.
Zum Verhältnis von Interaktion, Organisation und Gesellschaft in der Therwiler Handschlag-Affäre. Eine systemtheoretische Analyse
Authors: Walthert Rafael , Frank Katharina , Stauffacher Daniela , Weber Urs 
Published: May 2021

Zusammenfassung
Der Beitrag baut auf Niklas Luhmanns Unterscheidung zwischen verschiedenen Typen sozialer Systeme auf, nämlich Interaktionen, Organisationen und einer durch funktionale Teilsysteme strukturierten Gesellschaft. Auf dieser Basis wird der Fall zweier Schüler in einer Schweizer Sekundarschule analysiert, die ihren Lehrerinnen mit religiöser Begründung den Handschlag verweigerten. Gezeigt wird, wie dieses Ereignis von verschiedenen Systemtypen als Problem bearbeitet und jeweils unterschiedlich beobachtet wurde, wobei speziell auch die Frage nach dem Stellenwert des Teilsystems Religion gestellt wird. Insbesondere der Zeitbedarf und der Stellenwert schriftlicher Kommunikation der verschiedenen Systeme erweisen sich als Faktoren, über die sich die unterschiedliche Rolle verschiedener Systemtypen in der Affäre verstehen lässt. Religion beeinflusste zunächst zwar die Interaktion im Klassenzimmer, schließlich fungierte sie aber eher als Thema von Recht, Politik und Massenmedien, als dass sich religiöse Kommunikation über den ursprünglichen Interaktionszusammenhang hinaus als einflussreich erwiesen hätte.
Kulturkampfnarrative im Gesetzgebungsprozess
Authors: Bürgin Martin 
Published: May 2021

Zusammenfassung
Vor dem Hintergrund der medialen Debatte um die beiden Therwiler Schüler, die sich mit Verweis auf religiöse Gründe weigerten, ihrer Lehrerin die Hand zu reichen, strebten Politikerinnen und Politiker im Kanton Basel-Landschaft an, die dortige Verfassung zu ändern. Dabei wurde auf rechtliche und erinnerungskulturelle Diskurse aus dem Kulturkampf des 19. Jahrhunderts – und auf solche, die dazu Bezug nehmen – verwiesen. Diese Verweise werden in einem (partiellen) Close Reading des Kommentars zur geplanten (letztlich aber nicht realisierten) Änderung der basellandschaftlichen Kantonalverfassung erörtert und in den konfligierenden Narrativen des liberalen und des konservativen Lagers verortet. Dabei wird der Kommentar als Dokument gelesen, in welchem spezifische Geschichtsbilder, politische Identitäten und das Recht als sozial konstruierte Entitäten verwoben werden – und in welchem spezifische Konstruktionen und Reifikationen von Identität und Alterität angelegt sind.
Topic drop in German: Empirical support for an information-theoretic account to a long-known omission phenomenon
Authors: Schäfer Lisa 
Published: May 2021

AbstractGerman allows fortopic drop(Fries 1988), the omission of a preverbal constituent from a V2 sentence. I address the underexplored question of why speakers use topic drop with a corpus study and two acceptability rating studies. I propose an information-theoretic explanation based on the Uniform Information Density hypothesis (Levy and Jaeger 2007) that accounts for the full picture of data. The information-theoretic approach predicts that topic drop is more felicitous when the omitted constituent is predictable in context and easy to recover. This leads to a more optimal use of the hearer’s processing capacities. The corpus study on the FraC corpus (Horch and Reich 2017) shows that grammatical person, verb probability and verbal inflection impact the frequency of topic drop. The two rating experiments indicate that these differences in frequency are also reflected in acceptability and additionally evidence an impact of topicality on topic drop. Taken together my studies constitute the first systematic empirical investigation of previously only sparsely researched observations from the literature. My information-theoretic account provides a unifying explanation of these isolated observations and is also able to account for the effect of verb probability that I find in my corpus study.

Published: May 2021

Abstract
Für Anwendungen, bei denen hohen Lasten mittels elektromechanischer Aktuatoren bewegt werden, spielt die statische axiale Steifigkeit der verwendeten Gewindetriebe eine wichtige Rolle. Simulationen bieten die Möglichkeit, diese Eigenschaft des Gewindetriebs bereits während der Auslegung bestimmen zu können. Ausgehend von Berechnungsmethoden zur Beschreibung der Lastverteilung innerhalb eines Planetenrollengewindetriebs wird ein Modell erstellt, welches die wesentlichen Einflussfaktoren für die Berechnung der statischen axialen Steifigkeit berücksichtigt. Die Validierung des Modells erfolgt mittels Prüfstandsversuchen unter hohen Lasten.
Crack Width Estimation Using Measurements of Central Deflection in ASTM C1609/C1609M
Authors: Bernard E. S. 
Published: May 2021

Abstract
The ASTM C1609/C1609M beam test, Standard Test Method for Flexural Performance of Fiber-Reinforced Concrete (Using Beam with Third-Point Loading), has been used for assessing the flexural performance of fiber-reinforced concrete (FRC) for many years. The procedure involves the application of third-point loading to a relatively short, simply supported beam that consequently cracks and experiences extension and pull-out of fibers across the crack. The flexural performance of FRC tested in this way is normally expressed as a function of vertical deflection at the center of the beam. This is limiting because central deflection is specific to this test and is difficult to relate to structural applications. However, the two halves of the cracked beam experience essentially rigid-body rotation about the crack, raising the possibility that the maximum crack width can be calculated as a function of central deflection. Crack width is a more useful assessment parameter because it can be related to many structural applications. In the current investigation, seven FRC mixtures were produced and tested in accordance with ASTM C1609/C1609M, with both central deflection and crack width measured in all tests. The maximum crack width was then calculated as a function of central deflection and compared with the measured values. The results indicate that crack width can be calculated with sufficient accuracy using only the central deflection and crack offset from the center, thereby permitting flexural performance to be expressed as a function of crack width without any change to the current test procedure. The coefficient of variation in postcrack flexural strength was found to be slightly smaller for the same set of specimens when expressed as a function of maximum crack width rather than central deflection.

Published: May 2021

Objective
Following the evolution of COVID-19 pandemic, reports pointed on a high prevalence of thyroiditis-related thyrotoxicosis. Interpretation of thyroid tests during illness, however, is hampered by changes occurring in the context of non-thyroidal illness syndrome (NTIS). In order to elucidate these findings, we studied thyroid function in carefully selected cohorts of COVID-19 positive and negative patients.

Design
Cohort observational study.

Methods
We measured TSH, FT4, T3 within 24 h of admission in 196 patients without thyroid disease and/or confounding medications. In this study, 102 patients were SARS-CoV-2 positive; 41 admitted in the ICU, 46 in the ward and 15 outpatients. Controls consisted of 94 SARS-CoV-2 negative patients; 39 in the ICU and 55 in the ward. We designated the thyroid hormone patterns as consistent with NTIS, thyrotoxicosis and hypothyroidism.

Results
A NTIS pattern was encountered in 60% of ICU and 36% of ward patients, with similar frequencies between SARS-CoV-2 positive and negative patients (46.0% vs 46.8%, P = NS). A thyrotoxicosis pattern was observed in 14.6% SARS-CoV-2 ICU patients vs 7.7% in ICU negative (P = NS) and, overall in 8.8% of SARS-CoV-2 positive vs 7.4% of negative patients. In these patients, thyroglobulin levels were similar to those with normal thyroid function or NTIS. The hypothyroidism pattern was rare.

Conclusions
NTIS pattern is common and relates to the severity of disease rather than SARS-CoV-2 infection. A thyrotoxicosis pattern is less frequently observed with similar frequency between patients with and without COVID-19. It is suggested that thyroid hormone monitoring in COVID-19 should not differ from other critically ill patients.
