Published: February 2021

Zusammenfassung
Die Ereignisse im März 2020 in Zusammenhang mit der Entwicklung der COVID-19 Erkrankungen zu einer Pandemie stellten Einrichtungen weltweit vor neue Herausforderungen. Der Beitrag reflektiert den Umgang mit der Krise an der Dienstleistungseinrichtung (DLE) Bibliotheks- und Archivwesen der Universität Wien und spannt den Bogen vom situativ angepassten Führungs- und Managementstil über den Umstieg auf einen rein virtuellen Betrieb bis zur Anpassung vieler Workflows an die geänderten Umstände. Ab Mai 2020 erfolgte die stufenweise Wiedereröffnung der physischen Bibliothek. Die Krise bedeutete insgesamt einen deutlichen Digitalisierungsschub für die Bibliothek, was auch eine Umfrage unter den Mitarbeiterinnen und Mitarbeitern am Ende des ersten Lockdowns belegt.
The language centre as a laboratory for innovation
Authors: Schaffner Sabina 
Published: February 2021

Abstract
This paper discusses the potential of language centres in higher education as laboratories for innovation. Despite their hybrid character as central service providers that are also defined by their teaching, their positioning at the academic periphery, and the lack of a mandate to do academic research, language centres still have an obligation to conduct research as a means of promoting innovation. The design-based research (DBR) approach in learning and teaching, in which teaching stakeholders examine learning processes in real situation, offers a suitable opportunity for language centres to overcome the restrictions placed upon them. DBR can be done using existing resources and the innovation potential of a language centre’s teaching staff. The leadership and management of the language centre must be made responsible for providing and/or enabling the necessary structural, material, and cultural conditions for such research. This paper discusses the DBR approach at language centres in higher education and its impact on leadership. It then gives two examples of the successful implementation of DBR at the Language Center of UZH and ETH Zurich.
Exploring the relationship between motivations, emotions and pragmatic marker use in English-medium instruction learners
Authors: Ament Jennifer , Barón-Parés Júlia , Pérez-Vidal Carmen 
Published: February 2021

Abstract
The aim of the present study is twofold: first, it compares full-English-medium instruction (EMI) and semi-EMI learners on a series of motivational and emotional factors (the ought to, and the ideal L2 self-motivational orientations, attitudes towards English, and foreign language anxiety and enjoyment). Second, it investigates the relationship between these individual differences (IDs) and pragmatic marker (PM) use. No previous studies have investigated these phenomena among semi and full EMI learners, despite the recognized need for more research into the effects of IDs and pragmatic learning in EMI settings. Participants were second and third-year EMI students. A monologue and an interaction task were used to obtain oral data, and questionnaires were used to gather data on IDs. Results showed that EMI and semi-EMI groups did not differ according to motivational orientation. However, there were significant differences between learner’s motivations depending on the year of study, where third year learners were more ought to self-motivated than second-year learners. Other findings revealed that both strong ought to L2 self-oriented learners as well as learners who enjoyed EMI demonstrated an increased frequency of PM use and that learners with positive attitudes towards English reported stronger ideal L2 selves.

Rif Berber: From Senhaja to Iznasen. A qualitative and quantitative approach to classification
Authors: Lafkioui Mena B. 
Published: February 2021

Abstract
By combining qualitative (synchronic and diachronic) and quantitative (algorithmic) approaches, this study examines the nature, structure, and dynamics of the linguistic variation attested in Berber of the Rif area (North, Northwest, and Northeast Morocco). Based on a cross-level corpus of data obtained from the Atlas linguistique des varieties berbères du Rif (Lafkioui 2007) and from numerous linguistic, sociolinguistic, and ethnographic fieldwork investigations in the area since 1992, this study shows that these Berber varieties form a language continuum with the following five stable core aggregates, which cut across administrative and political borders: Western Rif Berber, West-Central Rif Berber, Central Rif Berber, East-Central Rif Berber, and Eastern Rif Berber. Furthermore, data mining studies made it possible to objectively identify the principal aggregate discriminators of the Rif Berber continuum, which are dealt with in the study. A special focus in the article is put on the interplay between system-internal and system-external parameters for the selection, diffusion, and transformation of variants in Rif Berber.

Abstract
The spatial and temporal evolution of the sandbody architecture of shallow-water deltas in open lacustrine basins is controlled by the classification of allocyclicity and autocyclicity. On the southwestern margin of the Ordos Basin, a braided river system deposited a shallow-water delta in the Late Triassic Period. Based on the principle of sequence stratigraphy and the hierarchical analysis of reservoir architecture, the spatial and temporal evolution of individual sandbodies in the Chang 81 member of the Yanchang Formation in the Zhenbei Oilfield is interpreted by utilizing data from cores, wells and outcrops. The research ideas are as follows: large deposition scale architectural elements (first- to third-order cycles, as defined by Miall) of different sequence levels are affected by allocyclicity associated with changes in tectonic activity, provenance, and sea level, and small deposition scale architectural elements (fourth- to fifth-order cycles, as defined by Miall) of different sedimentary facies mainly consist of individual sandbodies that are affected by autocyclicity associated with lake-level changes caused by various river processes. Based on previous studies, the results are as follows. The sedimentary characteristics of shallow-water deltas have been verified by core and outcrop data. In addition, three ultrashort-term cycles are identified on the basis of boundary sequences and lithofacies’ sequences in the outcrop section of the Rui River, and three sedimentary evolution stages of the delta front are defined. Finally, according to well data, five types of architectural elements at the level of single sandbodies are identified. The vertical superimposition and lateral contact relationships of different architectural elements indicate that during the three sedimentary evolution stages, the hydrodynamics weakened, strengthened slightly, and finally weakened substantially. Among the 20 kinds of architectural element spatial combination patterns formed by single sandbodies, primary and secondary sandbodies have great potential for hosting remaining oil. In the process of architectural spatiotemporal evolution, the geometry and connectivity of the underwater distributary channel gradually weakened, and the spatial relationship between the underwater distributary channel and other architectural elements increased. This article proposes a new method for researching shallow-water deltas and has some guiding significance for exploiting the remaining oil in oil fields.

The Rietveld refinements of X-ray powder diffraction data determined and confirmed the crystal structure of the compositions. DC electrical conductivity indicated the conduction behaviour and diffuse reflectance spectroscopy confirmed the semiconducting nature of the compounds. Room temperature photoluminescence results exhibited two type of emission namely blue-green and green emission in the visible region.
On the evaluation of the constrained studded pressing method for producing nanocrystalline copper sheets
Authors: Torkestani Ahad , Dashtbayazi Mohammad Reza 
Published: February 2021

Abstract
In this study, the experimental setup of a constrainedstudded- pressing method (CSP) as a severe plastic deformation process was investigated to produce nano-crystalline copper sheets. The sheets were CSPed up to 35 passes. The crystallite size and the dislocation density of CSPed samples were calculated by X-ray-diffraction pattern analysis. Also, tensile tests were used to investigate the mechanical properties of the CSPed samples. The results revealed that increasing the number of CSP passes augmented the density of dislocations, reduced the crystallite size to 124 nm (while for the as-received sample it was about 7.8 lm), enhanced the yield-strength and the ultimate-tensile- strength, and lowered the elongation of samples. This study for the first time has challenged the ability of the CSP method to produce nanocrystalline materials.
Glass formation, nanocrystallisation and magnetic properties of the (Fe1–xCox)79Nb3B18 (x = 0, 0.15, 0.3, 0.45, 0.6, 0.75) metallic glasses

Published: February 2021

Abstract
The glass-forming ability (GFA), nanocrystallisation, electrical resistivity and soft magnetic properties of (Fe1-xCox)79Nb3B18 (x = 0, 0.15, 0.3, 0.45, 0.6, 0.75) glassy alloys were investigated. We found that the substitution of Fe by Co is beneficial for improving the GFA. As-spun (Fe0.55Co0.45)79Nb3B18 glassy alloys show the best GFA, along with excellent soft magnetic properties in the supercooled liquid region, with a saturation magnetisation and coercivity of 140 A · m2 · kg-1 and 19.9 A · m-1, respectively, at 60 K. With increasing Co content, the electrical resistivity initially decreases rapidly, and then fluctuates around approximately 70 ± 4 μΩ cm. With increasing the annealing temperature, the saturation magnetisation improves initially, but then decreases for the (Fe0.4Co0.6)79Nb3B18 alloy, and the coercivity does not significantly improve. These newly developed FeCoNbB multicomponent alloys exhibit appreciable GFA, good magnetic properties and low material cost, and they can serve as a promising soft magnetic material for use in industrial applications.

Next generation wireless networks are the need of the hour with reliable, high bandwidth, low Bit Error Rate (BER), high Signal to Noise Ratio (SNR), large network capacity, etc. for a paradigm shift to all optical networks from the prevailing conventional electro optic network due to the various benefits of optical links such as enormous bandwidth and extremely low losses. This paper presents a primitive overview of the foregoing technologies and then move on to encapsulating the contemporary techniques to enhance the system performance. For this, preceding limitation and their respective improvement measures from literature of fiber communication and its integration with the next generation networks mainly based upon Radio over Fiber (RoF), Fiber to the Home (FTTH) and Free Space Optics (FSO) are discussed. The advancement in the domain of optical wireless communication utilizing various methodologies is summarized. Finally, we conclude by incorporating various cost reduction methodologies developed which may further be explored to make next generation networks more promising.

On strongly nonlinear gravity waves in a vertically sheared atmosphere
Authors: Schlutow Mark , Voelker Georg S. 
Published: February 2021

Abstract
We investigate strongly nonlinear stationary gravity waves which experience refraction due to a thin vertical shear layer of horizontal background wind. The velocity amplitude of the waves is of the same order of magnitude as the background flow and hence the self-induced mean flow alters the modulation properties to leading order. In this theoretical study, we show that the stability of such a refracted wave depends on the classical modulation stability criterion for each individual layer, above and below the shearing. Additionally, the stability is conditioned by novel instability criteria providing bounds on the mean-flow horizontal wind and the amplitude of the wave. A necessary condition for instability is that the mean-flow horizontal wind in the upper layer is stronger than the wind in the lower layer.

Published: February 2021

Abstract

Introduction
Carpal tunnel syndrome (CTS) is a condition caused by chronic compression of the median nerve. The diagnosis is made mainly on the basis of clinical image and confirmed with electrodiagnostic testing (electromyography and nerve conduction study); however, these methods do not always aid in reaching the diagnosis of CTS. Moreover, they are invasive examinations, unpleasant for the patient and have to be performed by a qualified physician.

Aim
An evaluation of the usefulness of dynamic thermography in the diagnosis of CTS.

Material and methods
Forty patients were included in the study group. CTS was diagnosed based on clinical examination and electromyography. Forty healthy volunteers were included in the control group. Each of the participants was examined thrice with dynamic thermography. The patient’s hands were first cooled down and then a thermal camera measured their return to normal temperature. The measurement was repeated on the dorsal and volar aspects of each hand.

Results
The results obtained in the study show that a relief of symptoms after carpal tunnel release does not correlate with thermal image. Moreover, the return to normal hand temperature was faster in the control group. In patients with unilateral CTS, no difference was observed in thermographic images of the affected and healthy hands.

Conclusions

Dynamic thermography can be useful in confirming CTS diagnosis.

Dynamic thermography does not allow for objective assessment of patient’s complaints in the postoperative period.

This method has currently limited clinical application. Due to complexity, it presently serves mainly scientific purposes.
Comparison of multiple flatfoot indicators in 5–8-year-old children
Authors: Žukauskas Saidas , Barauskas Vidmantas , Čekanauskas Emilis 
Published: February 2021

Abstract

Background
The foot posture is age dependent. The purpose of this study was to investigate the relationship between the 6-item version of the foot posture index (FPI) and other clinical, foot anthropometric, radiological measurements for the foot position in 5–8-year-old children.

Methods
A total of 301 participants with a mean age of 6.4  ±  1.14 years were enrolled in the study. Children were examined physically, clinically, and radiologically to measure the FPI and navicular drop (ND) test, resting calcaneal stance position (RCSP) angle, Chippaux–Smirak index (CSI), Staheli index (SI), calcaneal pitch (CP) angle, talocalcaneal angle (TCA), and the first lateral metatarsal angle. Tibial torsions, internal rotation of the hip as an indirect method of femoral anteversion, and Beighton scale were analyzed for factors associated with flatfoot prevalence.

Results
The study included children with normal and flexible flatfeet. Statistical analysis showed a significant FPI score correlation with other parameters (SI, CSI, RCSP, ND, CP, TMA, and TCA showed strong and moderate correlations, p < 0.001). Overall, the strongest associates are CSI (β = 0.34) and ND (β = 0.28). Other indicators have relatively small relationships with the FPI.

Conclusion
A positive correlation was observed between FPI-6 and ND test, CSI in 5–8-year-old children. All three prominent foot posture indicators (FPI-6, ND, and CSI) might be used as a primary or preferred tool in clinical practice.

Determination of readiness for laying based on material moisture, corresponding relative humidity, and water release
Authors: Strangfeld Christoph , Kruschwitz Sabine 
Published: February 2021

Abstract
The moisture content of the subfloor has to be determined before installation to avoid damage to the floor covering. Only if readiness for layering is reached, can an installation without damage be expected in all cases. In general, three approaches exist to measure residual water content: determination of moisture content, determination of water release, or determination of the corresponding relative humidity. All three approaches are tested under laboratory conditions at eight screed types including two samples thicknesses in each case. Moisture content and water release are measured by sample weighing, the corresponding relative humidity is measured by embedded sensors. All three approaches are compared and correlated. The evaluations show only a weak correlation and, in several cases, contradicting results. Samples are considered ready for layering and not ready for layering at the same time, depending on the chosen approach. Due to these contradicting results, a general threshold for a risk of damage cannot be derived based on these measurements. Furthermore, the experiment demonstrates that the measurement of corresponding relative humidity is independent of the screed type or screed composition considered. This makes humidity measurement a potentially very promising approach for the installation of material moisture monitoring systems.
Ultrasonic testing and evaluation of moisture-dependent elastic properties of fir wood
Authors: Aydin Tugba Yilmaz , Kucukkose Ayşegul 
Published: February 2021

Abstract
With respect to their relevance for wood-related technologies, moisturedependent elastic engineering parameters of Taurus fir (Abies Cilicica (Antoine et Kotschy) Carriere) are determined from ultrasound longitudinal (2.3 MHz) and shear (1 MHz) wave velocities. The dynamic Young’s and shear modules of characteristic axes and planes decrease significantly down to 17 % at increased moisture content due to decreased wave velocities. Moisture-dependent R2 values of the modules range from 0.88 to 0.99. However, Poisson’s ratios exhibit inconsistent moisture dependent behavior. Remarkable differences between ultrasound findings and the published results from compression tests are observed. Generally, the elastic values of wood from ultrasonic testing are reported higher than from mechanical tests. In contrast we find lower values as well. The critical issue of different ultrasound velocity sensitivity at selected directions is highlighted.
Blasphemy Law as a Structural Violence: A Challenge for Maintaining Sustainable Peace
Authors: Pratiwi Cekli Setya , Sunaryo Sidik 
Published: February 2021

Abstract
Blasphemy law (BL) has become a central issue for the international community in various parts of the world in the last three decades. In almost every case involving the BL, especially in Muslim countries, such as Pakistan, Malaysia, and Indonesia, they are always responded with violence or threats of attack that cause many victims, loss of homes, damage to places of worship, evictions, stigma of being heretical, severe punishments, or extra-judicial killings. When international human rights law (IHLR) and declaration of the right to peace are adopted by the international community, at the same time, the number of violence related to the application of BL continues to increase. This paper aims to examine the ambiguity of the concept of the BL in Pakistan, Indonesia, and Malaysia, and how its lead to the weak of enforcement that creates social injustice and inequality. Then, referring to Galtung’s theory of structural violence and other experts of peace studies, this paper argues that blasphemy law should be included as a form of structural violence. Therefore its challenges these States to reform their BL in which its provisions accommodate the state’s neutrality and content high legal standards. Thus, through guarantee the fully enjoyment of human rights for everyone may support the States to achieve sustainable peace.
