Psychometric Validation of the Bangla Fear of COVID-19 Scale: Confirmatory Factor Analysis and Rasch Analysis.

Abstract: The recently developed Fear of COVID-19 Scale (FCV-19S) is a seven-item uni-dimensional scale that assesses the severity of fears of COVID-19. Given the rapid increase of COVID-19 cases in Bangladesh, we aimed to translate and validate the FCV-19S in Bangla. The forward-backward translation method was used to translate the English version of the questionnaire into Bangla. The reliability and validity properties of the Bangla FCV-19S were rigorously psychometrically evaluated (utilizing both confirmatory factor analysis and Rasch analysis) in relation to socio-demographic variables, national lockdown variables, and response to the Bangla Health Patient Questionnaire. The sample comprised 8550 Bangladeshi participants. The Cronbach α value for the Bangla FCV-19S was 0.871 indicating very good internal reliability. The results of the confirmatory factor analysis showed that the uni-dimensional factor structure of the FCV-19S fitted well with the data. The FCV-19S was significantly correlated with the nine-item Bangla Patient Health Questionnaire (PHQ-90) (r = 0.406, p < 0.001). FCV-19S scores were significantly associated with higher worries concerning lockdown. Measurement invariance of the FCV-19S showed no differences with respect to age or gender. The Bangla version of FCV-19S is a valid and reliable tool with robust psychometric properties which will be useful for researchers carrying out studies among the Bangla speaking population in assessing the psychological impact of fear from COVID-19 infection during this pandemic.

Interlayer hydrogen-bonded covalent organic frameworks as high-performance supercapacitors

Abstract: Covalent organic frameworks (COFs) have emerged as promising electrode materials in supercapacitors (SCs). However, their insoluble powder-like nature, poor capacitive performance in pristine form, integrated with inferior electrochemical stability is a primary concern for their long-term use in electrochemical devices. Keeping this in perspective, herein we report a redox active and hydrogen bonded COF with ultrahigh stability in conc. H2SO4 (18 M), conc. HCl (12 M) and NaOH (9 M). The as-synthesized COF fabricated as thin sheets were efficiently employed as a free-standing supercapacitor electrode material using 3 M aq. H2SO4 as an electrolyte. Moreover, the pristine COF sheet showcased outstanding areal capacitance 1600 mF cm–2 (gravimetric 169 F g–1) and excellent cyclic stability (>100 000) without compromising its capacitive performance or Coulombic efficiency. Moreover, as a proof-of-concept, a solid-state supercapacitor device was also assembled and subsequently tested.

Preparation, Characterization, and Performance of Fe−ZSM-5 Catalysts

Abstract: A number of iron−ZSM-5 catalysts have been prepared and characterized by X-ray absorption spectroscopy using fluorescence detection, electron spectroscopy, temperature-programmed reduction, infrared spectroscopy, and electron microscopy. Iron has been introduced by aqueous exchange, by a novel method recently proposed by Feng and Hall (Catal. Lett. 1996, 41, 45), by exchange from a rigorously dried methanolic solution accompanied by agitation with ultrasound, and by a method intended to promote solid-state exchange. The degree of interaction with the zeolite framework has been probed by examining the effect on the zeolite proton OH band in the infrared spectrum. Less than 30% of the protons were exchanged from aqueous solution, but almost 80% exchange was achieved using ultrasound, as well as by the method reported by Feng and Hall (FH). Initially, both methods exhibited mainly isolated metal ions; however, calcination of the samples prepared according to FH exhibited rather large oxide clusters. After aq...

The invisibility of skilled female migrants and gender relations in studies of skilled migration in Europe

Abstract: This paper examines the reasons for the invisibility of skilled female migrants in studies of skilled migration in Europe. The choice of research agendas has played a major part in rendering women invisible. The emphasis has generally been on transnational corporations, which, especially in their higher ranks, remain resolutely male-dominated. The presence of migrants in welfare sectors (i.e. education, health and social services), which are strongly feminised, has been ignored. Feminist research has also tended to obscure the role of skilled migrants in its emphasis on the unskilled. Theoretical and methodological developments in studies of migration have also made few inroads into our understanding of skilled migration.
