Digitale Disruption und biografische Verarbeitung
Authors: Kels Peter , Dröge Kai , Gisin Leila , Abbas Marina 
Published: November 2023

Zusammenfassung
Die Digitalisierung als globaler Megatrend transformiert nicht nur Branchen, Organisationen und Berufe, sondern erzeugt Veränderungsherausforderungen und Pfadbrüche, mit denen auf subjektiv-berufsbiografischer Ebene umgegangen werden muss. Unser Beitrag beleuchtet die Implikationen digitaler Transformationsprozesse in drei wissensintensiven Berufsfeldern (Kommunikation, Finanzen, ICT) auf Ebene der Biografiegestaltung. Auf Grundlage berufsbiografischer Fallanalysen anhand von Interviews rekonstruieren wir, wie Wissensarbeitende die Umbrüche in ihrem beruflichen Umfeld subjektiv erleben und im Lichte eigener Vorstellungen eines gelungenen Lebens und einer kohärenten beruflichen Biografie zu bewältigen und mitzugestalten versuchen. Unsere Ergebnisse zeigen, dass die Fähigkeit, berufliche Transitionen trotz ihres potenziell krisenhaften und erschütternden Charakters in eine kohärente, identitätsstiftende biografische Erzählung einzuweben, ein entscheidender Faktor gelingender Biografiegestaltung in Zeiten des Umbruchs ist.

Abstract

Objectives
According to ISO 15189:2022, analytical performance specifications (APS) should relate to intended clinical use and impact on patient care. Therefore, we aimed to develop a web application for laboratory professionals to calculate APS based on a simulation of the impact of measurement uncertainty (MU) on the outcome using the chosen decision limits, agreement thresholds, and data of the population of interest.

Methods
We developed the “APS Calculator” allowing users to upload and select data of concern, specify decision limits and agreement thresholds, and conduct simulations to determine APS for MU. The simulation involved categorizing original measurand concentrations, generating measured (simulated) results by introducing different degrees of MU, and recategorizing measured concentrations based on clinical decision limits and acceptable clinical misclassification rates. The agreements between original and simulated result categories were assessed, and values that met or exceeded user-specified agreement thresholds that set goals for the between-category agreement were considered acceptable. The application generates contour plots of agreement rates and corresponding MU values. We tested the application using National Health and Nutrition Examination Survey data, with decision limits from relevant guidelines.

Results
We determined APS for MU of six measurands (blood total hemoglobin, plasma fasting glucose, serum total and high-density lipoprotein cholesterol, triglycerides, and total folate) to demonstrate the potential of the application to generate APS.

Conclusions
The developed data-driven web application offers a flexible tool for laboratory professionals to calculate APS for MU using their chosen decision limits and agreement thresholds, and the data of the population of interest.

Abstract
This study aims to contribute to the valorizing of aromatic and medicinal plants of Morocco by studying the antioxidant and antifungal properties of the essential oils (EOs) of Allium sativum (AS) (garlic) and Urginea maritima (Syn. Drimia maritima) tested in vitro. After the hydrodistillation of EOs, we determined their physicochemical indices according to an international standard (Moroccan ISO standard), and the chemical composition of the oils was studied by gas chromatography coupled with mass spectrometry (GC-MS). Then, the antioxidant properties were determined using the free radical scavenging capacity of 2,2-diphenyl-1-picrylhydrazyl and the ferric-reducing antioxidant power of these oils. The evaluation of the antifungal activity was carried out by the direct contact method against two fungal strains, Fusarium oxysporum and Fusarium equiseti. GC-MS analysis revealed a significant percentage of terpenes in U. maritima EO, with terpinolene (21.82%) and estragole (6.24%) as the main compounds. Biological tests have demonstrated the remarkable antioxidant activities of this EO compared with AS EO, with an IC50 of 1.03 mg/mL and an RP0.5 of 1.60 mg/mL. On the other hand, while A. sativum (garlic) EO showed exceptional antifungal activities, with 100% inhibition and MICs of 0.5 µL/mL for F. equiseti and 2.5 µL/mL for F. oxysporum. Also, regardless of its antioxidant properties being moderate, this EO stands out for its efficacy against fungal infections of the Fusarium genus. In summary, the results suggest that U. maritima EO could be used as a natural source of antioxidants, while garlic EO could be considered a potentially effective treatment against fungal infections caused by Fusarium fungi.
A mathematical analysis of the impact of maternally derived immunity and double-dose vaccination on the spread and control of measles

Abstract
Measles is a highly communicable viral infection that mostly affects children aged 5 years and below. Maternal antibodies in neonates help protect them from infectious diseases, including measles. However, maternal antibodies disappear a few months after birth, necessitating vaccination against measles. A mathematical model of measles, incorporating maternal antibodies and a double-dose vaccination, was proposed. Whenever

{{\mathcal{ {\mathcal R} }}}_{0}\lt 1

, the model is shown to be locally asymptotically stable. This means that the measles disease can be eliminated under such conditions in a finite time. It was established that

ℛ

{{\mathcal{ {\mathcal R} }}}_{0}

is highly sensitive to

(the transmission rate). A numerical simulation of the model using the Runge-Kutta fourth-order scheme was carried out, showing that varying the parameters to reduce

will help control the measles disease and ultimately lead to eradication. The measles-mumps-rubella (MMR) vaccine dosage should be adjusted for babies from recovered mothers, as maternal antibodies are usually high in such babies and can interfere with the effectiveness of the MMR vaccine.
Biogenic synthesis of silver nanoparticles usingConsolida orientalisflowers: Identification, catalytic degradation, and biological effect
Authors: Karan Tunay 
Published: November 2023

AbstractSilver nanoparticles have attracted great attention due to their important usage areas recently. Silver nanoparticles were synthesizedvia Consolida orientalisflowers by green approach. The spectroscopic analyses characterized the synthesized silver nanoparticles (AgNPs@Co). The surface plasmon resonance of AgNPs@Co was determined as 425 nm by UV-Vis. The particle size was determined by X-ray diffraction (XRD) as 9.7 nm using the Scherrer equation. XRD analysis at 2θwith the angle of 38.17°, 44.29°, 57.49°, and 77.36° corresponded to planes [111, 020, 202, and 131] demonstrating the fcc structure. In addition, transmission electron microscopy analysis presented the particle size to be 11.9 nm as spherical. The functional moiety of bioactive compounds was displayed by Fourier-transform infrared spectroscopy analysis, and a characteristic hydroxyl was detected at 3,274 cm−1. The zeta potential revealed the stability of nanoparticles as −20.3 mV. The signals at 2.3–3.4 keV in energy-dispersive X-ray spectroscopy proved the nanostructure. The catalytic activity of AgNPs@Co was executed using methylene blue in the treatment of sodium borohydride and degradation was determined as 71% in 45 min. Antioxidant of extract and nanoparticles was carried out using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and superoxide assays. The nanoparticles and extract exhibited good antioxidant activity with the values of 9.3 ± 0.2 and 11.2 ± 0.6 in the DPPH assay, respectively, in comparison with the standard butyl hydroxyanisole (6.5 ± 0.4). The silver nanoparticles may be a good antioxidant agent for drug development and the food industry.
Von der Produkt- zur Prozessorientierung: (Info-)DaF-Trends in den 1990er Jahren
Authors: Witte Arnd 
Published: November 2023

Zusammenfassung
Die 1990er Jahre waren geprägt durch (a) die Diskussion einer Strukturreform des Faches DaF im Gefolge der Vereinigung Deutschlands, (b) das Aufkommen neuer technologischer Medien, (c) eine Neuorientierung interkultureller Lehr- und Lernprozesse hinsichtlich der Aufwertung der kulturellen Vernetzung der Lernenden sowie (d) eine generelle Verlagerung von der sprachlichen Produkt- zur psycholinguistisch geprägten Prozessorientierung des Lernkonzeptes in DaF-Theorie und -Praxis. Die Prozessorientierung erstreckte sich jedoch aufgrund des vorherrschenden mentalistischen Paradigmas nicht auf vorbewusste Prozesse des resonanten Leibes, obgleich sie die (inter-)subjektive Wahrnehmung strukturieren und Intentionalität orientieren. Im zweiten Teil des Artikels werden phänomenologische und neurophysiologische Forschungsergebnisse diskutiert, die nahelegen, dass die explizite Einbeziehung des handelnden Leibes in den Fremdsprachenunterricht einen konstruktiven Einfluss auf den Erwerb und die Retention des Erlernten hat, da das Erlernte sich in Leib und Kognition als multimodales semiotisches Repertoire ablagert.

Zusammenfassung
Dieser Beitrag geht der Frage nach, welche Entwicklungen im Fach Deutsch als Fremd- und Zweitsprache in den Jahren 2010 bis 2020 im Spiegel der Zeitschrift Informationen Deutsch als Fremdsprache (Info DaF) sichtbar werden. Dabei werden drei Aspekte herausgegriffen, nämlich 1) die Erweiterung und Ausdifferenzierung der Themen und Forschungsgegenstände sowie der theoretischen und empirischen Zugänge, 2) die Erweiterung der betrachteten Lernkontexte, einschließlich digitaler, und 3) die Weiterentwicklung und Konsolidierung des Selbstverständnisses des Fachs. Abschließend wird mit Mehrsprachigkeit ein Thema diskutiert, das in der Fremdsprachenforschung und in der Linguistik in dem betrachteten Jahrzehnt zentral war und in Info DaF zwar in einigen Beiträgen erkennbar wird, aber bisher nicht im Fokus steht.
Introduction. Epigraphy, the Qurʾān, and the Religious Landscape of Arabia
Authors: Grasso Valentina A. , Davitashvili Ana , Abuhussein Nadja 
Published: November 2023

AbstractA wide range of archaeological finds is rapidly expanding our knowledge of the pre-Islamic cultural milieu and the political structures of the Arabian Peninsula during Late Antiquity, and thereby of the Qurʾān’s cultural context. This material can offer a complementary reading to the literary accounts on pre-Islamic Arabia, which were mostly composed outside of Arabia or long after the late antique period. There is a growing need to make the recent exciting discoveries of scholars working on the Qurʾān and Arabia more widely accessible to historians who may not have a solid background in archaeology and epigraphy. As such, the ERC project “The Qur'an as a Source for Late Antiquity” (QaSLA) organized a conference, titled “Epigraphy, the Qur'an, and the Religious Landscape of Arabia”, which took place in Tübingen on 8 – 10 September 2022. The three-day international conference brought together specialists in epigraphy as well as scholars of the Qurʾān to explore how recent epigraphic and archaeological findings and research have been changing our understanding of the Qurʾān and the Arabian religious, cultural, and political landscape. Accordingly, the conference sought to integrate new archaeological finds with ongoing studies on the genesis of the Qurʾān, its Arabian background, and the broader cultural milieu of pre-Islamic Arabia with a special focus on the dawn of Islam. The conference also featured an important contribution by Peter Webb on pre-Islamic poetry, another neglected corpus of inquiry into the history of pre-Islamic Arabia. Aiming to foster discussion between scholars, each panel was paired with a specialist on the Qurʾān or the wider history of Arabia.
The Hajj Before Muhammad: The Early Evidence in Poetry and Hadith
Authors: Webb Peter 
Published: November 2023

AbstractScholarly debate on the nature of the Hajj before Muhammad and radical questions of whether Mecca was a ritual site at all in pre-Islamic times are answerable from the large corpus of pre-Islamic poetry, which has been underutilised as a source for pre-Islamic history. This paper reveals the poetry to be both a reliable and valuable witness. It demonstrates that the Hajj was performed in the generation before Muhammad in substantially similar terms to subsequent Muslim practice. Some modifications and shifts are discernible, but ritual continuity emerges as a major theme. The poetry also underscores the restricted ambit of the pre-Islamic Hajj: we uncover a highly-localised ritual followed primarily by groups living near Mecca – the expansion of the Hajj into a pan-Arabian phenomenon with an intimate role in informing communal identity and political power are new in the Islamic period. This paper closes with comparison of the poetry and hadith on the Hajj, which reveals a major Muslim-era reinterpretation of the pilgrimage as an Abrahamic rite.
The Development of the Hijazi Orthography
Authors: van Putten Marijn 
Published: November 2023

Abstract
This paper examines the main orthographic innovations of the early Islamic orthography in comparison to the Nabataean orthography and traces through new epigraphic evidence when and where these innovations came to be used. It is shown that a number of them clearly develop already in the pre-Islamic period. Besides this, the paper looks at the complexities of Arabic orthography and morphophonological spelling as it is reflected in the Quranic orthography as well as pre-Islamic inscriptions and argues that the early Islamic orthography represents the continuation of a developed Hijazi scribal tradition.

Published: November 2023

Abstract
Recently, significant efforts have been devoted to guaranteeing high-quality communication services in fast-moving scenes, such as high-speed trains. The challenges lie in the Doppler effect that shifts the frequency of the transmitted signal. To this end, the recent emergence of spatiotemporal metasurfaces offers a promising solution, which can manipulate electromagnetic waves in time and space domain while being lightweight and cost-effective. Here we introduce deep learning-assisted spatiotemporal metasurfaces to automatically and adaptively neutralize Doppler effect in fast-moving situations. A tandem neural network is used to establish a rapid connection between on-site targets and time-varying series of spatiotemporal metasurfaces, endowing the capability of on-demand beamforming with Doppler effects offset. Moreover, oblique incidence problems are also studied in practice, which can be used for relieving multipath effect. In the microwave experiment, we fabricate the intelligent spatiotemporal metasurfaces and demonstrate the potential to fulfill Doppler-offset beamforming under oblique incidence.
Demand in a Portfolio-Choice Environment: The Evolution of Telecommunications

Published: November 2023

Abstract
The introduction of a new good (or service) often creates situations in which consumers may choose to consume an extant good, a new good, both goods, or neither. Understanding the evolution and determinants of consumer demand in these situations can be quite important to economic policy formation, and especially so in network industries experiencing the entry of new services. In this study, we draw upon a database of over 180,000 individual household choices of fixed and/or mobile telephone subscriptions over 2003–2010 to improve insight into both the structure and evolution of consumer demand in such portfolio-choice settings. Congruent with our underlying consumer utility model, we find that cellphone service complements household member mobility: Households that are more often “on the go” favor mobile services. We also find the presence of network effects that impact the demand for mobile telephone services. Finally, we find that own- and cross-price elasticities of fixed and mobile telephony services demonstrate marked differences among demographic groups and across income levels.

Published: November 2023

Abstract
The effect of nozzle lip thickness and velocity ratio on coaxial subsonic jet mixing, at different Mach numbers, has been studied experimentally and numerically. Decay of coaxial subsonic jets emanating from coaxial nozzles of lip thickness 0.7, 1.7 and 2.65 mm with velocity ratio (VR) from 0.2 to 1.0 at primary jet exit Mach numbers of 0.6, 0.8 and 1.0 has been studied. Free jet without co-flow (VR0) was also studied for comparison. Jet centerline Mach number decay, turbulence and velocity variation in the radial direction are analyzed. The results show that mixing the coaxial jet at a low-velocity ratio is better than a high-velocity ratio, at all Mach numbers of the present study. The nozzle lip thickness has a significant influence on the secondary jet. Mixing of the jet in the presence of VR0.2 coaxial jet is found to be the highest. Characteristic decay of Mach 0.8 and 1.0 jet for lip thickness 1.7 and 2.65 mm is faster than lip thickness 0.7 mm. For a given lip thickness, increasing of velocity ratio is found to retard the mixing between primary and secondary jets.
Displacing the PStem
Authors: Elkins Noah 
Published: November 2023

Abstract
Much debate in prosodic phonology has centered on the question of recursive prosodic layers versus independent constituents. Recently, Downing and Kadenge (Downing, Laura & Maxwell Kadenge. 2015. Prosodic stems in Zezuru Shona. Southern African Linguistics and Applied Language Studies 33(3). 291–305, Downing, Laura & Maxwell Kadenge. 2020. Re-placing the PStem in the prosodic hierarchy. The Linguistic Review 37(3). 433–461) have advocated for a unique prosodic constituent, the PStem, to match stem-level phonology. They argue that the stem level should not be sensitive to canonically word-level phenomena such as minimality and culminativity. Alternatively, Itô and Mester (Itô, Junko & Armin Mester. 2007. Prosodic adjunction in Japanese compounds. MIT Working Papers in Linguistics. 97–111 et seq.) propose that the PStem/PrWd division can be collapsed into recursive PrWd levels, in which any recursive layer can have any given set of properties. In this paper, I hope to add to this debate by showing that Downing and Kadenge’s idea of specifically stem-level processes is falsifiable in light of new empirical evidence from a number of unrelated languages. In terms of the recursion question, I show that there are two types of language behavior with respect to stem- versus word-level phonology: one in which stem and word are the loci of the distinct processes, and one in which stem and word show the same behavior (“recursive identity”). I conclude by showing that arguments intending to reduce recursive identity to cyclicity encounter their own suite of problems.

AbstractAcupuncture at Lianquan (CV23) acupoint has been shown to improve swallowing function in poststroke dysphagia (PSD). This improvement is supposed to be associated with the regulation of neuronal activity in the contralateral primary motor cortex (M1), while the underlying mechanism still needs to be elucidated. Perineuronal nets (PNNs) are well-known to be involved in the regulation of neuronal activity. Thus, we here aimed to detect the role of PNNs in the contralateral M1 hemisphere in the electroacupuncture (EA)-mediated effect in male mice. The results were obtained from a combination of methods, includingin vitroslice electrophysiological recording,in vivoelectrophysiological recording, and immunofluorescent staining in male mice. These results showed a decrease of the excitatory postsynaptic currents (sEPSCs) and no alteration of the inhibitory postsynaptic currents (sIPSCs) in the GABAergic neurons and the tonic inhibition in the excitatory neurons in the contralateral M1 after stroke induction, and EA recovered the impaired sEPSCs in the GABAergic neurons. We further found that the effect of EA-induced increase of c-Fos expression, enhancement of spike firing, potentiation of sEPSCs in the excitatory neurons, and improvement of swallowing function were all blocked by the removal of PNNs in the contralateral M1. In conclusion, the PNNs in the contralateral M1 was suggested to be participated in stroke pathogenesis and might be associated with the EA-mediated swallowing function rehabilitation of PSD in male mice. Our study provides insight into how PNNs might be involved in the mechanism of EA treatment for stroke rehabilitation.
