Application of the protection motivation theory to understand determinants of compliance with the measure of banning gathering size >4 in all public areas for controlling COVID-19 in a Hong Kong Chinese adult general population
Authors: Yu Yanqiu , Lau Mason M. C. , Lau Joseph T. F. 
Published: May 2022

BackgroundRestriction of gathering size in all public areas is a newly and commonly exercised governmental social distancing policy during the COVID-19 pandemic. Its effectiveness depends on the general public’s compliance. This study applied the Protection Motivation Theory (PMT) to investigate determinants (i.e., perceived severity, perceived susceptibility, perceived response efficacy, and perceived self-efficacy) of compliance with the social distancing policy of banning gathering of >4 people in all public areas (BG4PA) in the Hong Kong general adult population.Methods300 participants were interviewed through a population-based telephone survey during April 21–28, 2020.ResultsThe compliance rate of BG4PA was high (78%). Adjusted for the background factors, multiple linear regression analysis found that perceived response efficacy and perceived self-efficacy were significantly and positively associated with compliance with BG4PA (p<0.05), while the associations between perceived severity/perceived susceptibility and compliance were of marginal significance (0.05<p<0.10). A stepwise linear regression model considered four PMT constructs as candidates; its final model only selected self-efficacy but not the other three PMT constructs.ConclusionsPMT can be applied to understand compliance with BG4PA. Perceived response efficacy and perceived self-efficacy were more influential than perceived severity and perceived susceptibility. Health promotion may focus on improving coping appraisal.
Language and identity of a Korean transnational youth in the U.S.
Authors: Pang Myoung Eun 
Published: May 2022

Abstract
The importance of multilingual use for the overall personal and educational development of transnational population is well documented, and many scholars have supported that language relates to identity. Given that adolescence is a critical period of identity construction, it is crucial to understand how transnational youth construct their transnational identity in adolescence, bordering across multiple languages and cultures in their everyday lives. Therefore, the current study examines the language and identity of one Korean transnational adolescent who lives with her family in the U.S. The purpose of this study is to explore how one Korean-American transnational adolescent youth navigates her identities utilizing her diverse linguistic and cultural repertoires in a range of contextual spaces. This qualitative case study collected semi-structured interview data to explore the following research questions: 1) How does a second generation Korean American transnational adolescent self-identify? and 2) How is her identity interconnected with her linguistic and cultural investment? This current study found that the participant has sites of specific identities as Korean or American: three distinct contexts of family, school, and community. In addition, the findings showed that the participant’s identity is related to her linguistic and cultural investment in transnational contexts.
Lack of analytical interference of dydrogesterone in progesterone immunoassays
Authors: Eggersmann Tanja K. , Wolthuis Albert , van Amsterdam Peter H. , Griesinger Georg 
Published: May 2022

Abstract

Objectives
Progesterone, a sex steroid, is measured in serum by immunoassay in a variety of clinical contexts. One potential limitation of steroid hormone immunoassays is interference caused by compounds with structural similarity to the target steroid of the assay. Dydrogesterone (DYD), an orally active stereoisomer of progesterone, is used for various indications in women’s health. Herein, we report a systematic in vitro investigation of potential interference of DYD and its active metabolite 20α-dihydrodydrogesterone (DHD) in seven widely used, commercially available progesterone assays.

Methods
Routine human plasma samples were anonymized and pooled to create three graded concentration levels of progesterone (P4 high, P4 medium, P4 low). Each pooled P4 plasma sample (6–7 mL) was spiked at high, medium, and “none” concentration with DYD/DHD and was divided into 0.5 mL aliquots. The blinded aliquots were analyzed by seven different laboratories with their routine progesterone assay (six different immunoassays and one liquid chromatography–tandem mass spectrometry assay, respectively) within the Dutch working group on endocrine laboratory diagnostics of the Dutch Foundation for Quality Assessments in Medical Laboratories.

Results
The sample recovery rate (P4 result obtained for sample spiked with DYD/DHD, divided by the result obtained for the corresponding sample with no DYD/DHD × 100) was within a ±10% window for the medium and high P4 concentrations, but more variable for the low P4 samples. The latter is, however, attributable to high inter- and intra-method variability at low P4 concentrations.

Conclusions
This study does not indicate any relevant interference of DYD/DHD within routinely used progesterone assays.

Abstract
In light of the recent COVID-19 pandemic, the demand for hydrogen peroxide has increased significantly due to its widespread use in disinfectant formulations. The present study aims to develop an efficient nanohybrid material as catalyst support for the successful hydrogenation of ethylanthraquinone for the production of hydrogen peroxide. Co-precipitation and wet impregnation methods were used to prepare nanohybrid Zr–Al–La supported Pd catalyst (Pd/Zr–Al–La). The high surface area (146.56 m2/g) of Zr–Al–La makes it suitable to use as support and causes to lower the mass transfer resistance and dispersion of active metal. XRF, BET, FTIR, and TGA were used to characterize the developed catalyst. The catalytic activity of the developed catalyst was studied using a high-pressure autoclave reactor to obtain a notable yield of H2O2 as 93.8% at 75 °C, 0.3 MPa, and 0.5 g of catalyst dose, a significant enhancement over the traditional Pd catalyst with Al2O3 support (63%) with the loss of active quinone compound. The mass transfer limitation of the reaction is high using only a Pd catalyst. The calculated mass transfer resistance of the reaction over Pd/Zr–Al–La catalyst was found to be moderate with a diffusion coefficient of the reactant (H2) as 0.0133 × 10−6 m2/s at 75 °C. It was also verified and confirmed with the Thiele modulus (calculated as 0.0314), no mass transfer resistance. The effectiveness factor (η

s
) was found to be 1.0, indicating the negligible mass transfer resistance in the hydrogenation reaction using Pd/Zr–Al–La catalyst.
Pragmatic impairment and COVID-19
Authors: Cummings Louise 
Published: May 2022

Abstract
The COVID-19 pandemic is the greatest global health threat in over 100 years. Its impact is seen in large numbers of premature deaths and the loss of economic stability for many millions of people. A significant number of people who contract the SARS-CoV-2 virus – the virus that causes COVID disease – experience symptoms many months after their acute illness. So-called Long COVID is now a recognized condition, with many affected individuals unable to return to work and engage in other daily activities. Among the complex symptoms of this condition is “brain fog”, a constellation of cognitive-linguistic problems that manifest as forgetfulness, word-finding difficulty, a lack of attention and concentration, and problems engaging in conversation. In this paper, I examine two women who had moderate COVID-19 infection during the first wave of the pandemic in Belgium and the UK. Both participants reported cognitive-linguistic difficulties several months after first becoming unwell. The UK participant is a native English speaker while the participant in Belgium speaks English as a second language. Case studies are used to examine their pre-morbid functioning and lifestyle, the onset and course of their COVID illness, and its impact on their language skills. It is argued that Long COVID has the potential to disrupt pragmatic and discourse skills even as structural language skills are intact. As such, this condition requires further systematic study by clinical linguists and speech-language pathologists.
External field alignment of nickel-coated carbon fiber/PDMS composite for biological monitoring with high sensitivity

Published: May 2022

Abstract
Flexible, pressure-sensitive composites can be prepared through the inclusion of electrically conductive particles as functional fillers into an elastomeric polymer matrix, which have been used for the applications of wearable devices for health monitoring and electronic skins. A key challenge associated with these composites is developing anisotropic pressure sensitivity while retaining their flexibility (or low filler content). Herein, we demonstrate a simple and scalable method for aligning anisotropic nickel-coated carbon fibers (NiCF) along with the thickness direction of a polymer matrix by applying a magnetic field. The aligning mechanisms and kinetics of NiCF in the polydimethylsiloxane (PDMS) precursor are revealed by in situ optical microscopy images while a magnetic field is applied. The aligned nickel-coated carbon fibers in the polymer effectively endow the composite films excellent pressure-sensitive performance. The pressure sensitivity of NiCF/PDMS composite films has been systematically studied and can be used for biological monitoring. We believe that this magnetic field assisted processing strategy provides a promising material solution for manufacturing fiber embedded polymer composites with enhanced pressure sensitivity, which is essential for future wearable health monitoring electronics and electronic skin.
The Case and Finiteness Restrictions of Italian Relativeche
Authors: Rugna Giuseppe 
Published: May 2022

AbstractThis paper addresses the restrictions of Italian relativeche‘what’ to finite environments and direct case gaps. While the standard analysis takes these restrictions to follow from the C status ofche, this paper argues for an alternative approach, according to whichcheis a DP, on a par with other interrogative and relative elements. Specifically, it is argued that relativecheis identical to interrogativecheand relativecui‘what.obl’ in the narrow syntactic derivation, up to the point oftransfer. Realization of relativecheis then blocked atextwith oblique case gaps by the more specificcui, along the lines of the Elsewhere Principle. The status ofcuias a specialized relative element is also discussed. The restriction to finiteness for relativecheis treated as an instance of a more general phenomenon that precludes bare DPs from occurring at the edge of infinitival relatives. Here I adopt and extend (Richards, Norvin. 2010.Uttering trees. Cambridge, Massachusetts: MIT Press) Distinctness Theory to account for the facts of Italian.

Authors: Mohanraj Saravanan 
Published: May 2022

Abstract
Home textile products manufactured and exported in huge quantities from Karur, Namakkal, Erode, and Salem are the established foremost important geographical locations centers in Southern India. The cotton fibers are less resistant to fire and that leads to unexpected accidents, thus there is an importance of the flame retardance tendency for home textiles. Eco-friendly herbal extract–dyed cotton has been investigated for tensile strength and flame retardant properties. The current research elaborately studies the antibacterial dyed cotton fabric materials in terms of improved flame retardant property through eco-friendly herbal extracts to cotton fabrics with simultaneous analysis on their tensile strength properties. The mangosteen-dyed cotton fabrics showed better results with specifications of 140 g/m2, plain weave with 40 % dye concentration, 240 g/m2, terry weave with 40 % dye concentration and untreated cotton fabrics of 140 g/m2 and 240 g/m2 had the tensile strength of 237.87 kg/cm2, 288.69 kg/cm2 and 238.38 kg/cm2, 288.47 kg/cm2. The flame response studies revealed the the burning time increases from 35 s for untreated 140 g/m2 plain cotton fabric to 50 s and 45 s for the fabrics dyed with mangosteen and borage. Correspondingly, the burning rate changes from 320 mm/min for untreated 140 g/m2 plain cotton fabrics to 290 mm/min and 300 mm/min for mangosteen- and borage-dyed fabrics, respectively. The limited oxygen index (LOI) test results showed that the borage-dyed fabrics exhibited little increased LOI values of 20 over the other treated samples on an average of LOI of 19 in comparison with the untreated cotton fabrics of LOI 18.
