Authors: Ali Syed Asim , Sadiq Iqra , Ahmad Tokeer 
Published: February 2023

AbstractGlobal warming and its cause and effects have necessitated the researchers to look beyond fossil and its derivatives. The scalability of CO2 reduction and H2 energy is one of the most enigmatic questions asked by the calamitous environmental changes happening across the world such as bushfires in Australia, Amazon and California or the melting of Arctic and Antarctic ice scalps. Thus, the research fraternity is keen to elevate the efficiency of CO2 reduction and H2 energy to the extent that the good chemical livestock produced by CO2 conversion and H2 fuel would become principal energy resources. In this quest, photocatalytic pathway envisions the environmentally benign protocol to bring about CO2 reduction and H2 production. Photo‐reduction of CO2 and H2 generation via photocatalytic water splitting by utilizing oxide based heterostructured photocatalysts are the promising approaches to carry out CO2 mitigation and H2 production efficiently ascribed to the advanced optoelectronic and structural superiority of oxides photocatalysts as discussed in this review.

Published: February 2023

AbstractIn this study, a poly (IL@MOF) composite monolithic column was synthesized using a simple and easy method. By adjusting the ratio of monomers, porogenic agents and cross‐linking agents, a macroporous composite monolith composed of metal organic framework (MOF) and ionic liquids (IL) was constructed. It was used as a high‐performance solid phase extraction (SPE) sorbent for the extraction of acacetin from medicinal and food homologous plants. The proposed SPE‐HPLC method for determination of acacetin had the advantages of high precision (0.06∼1.00 %), wide linear range (0.01∼250 μg mL−1) and low detection limits (3.26 ng mL−1). The poly (IL@MOF) monolithic column had excellent repeatability as an adsorbent. After 300 adsorption/desorption cycles, the corresponding chromatographic signal had no obvious change. These results indicated that the poly (IL@MOF) composite monolithic column was an ideal adsorbents and that the proposed method had potential for the enrichment and purification of flavonoids from medicinal and food homologous plants.

Published: February 2023

AbstractSolid solutions Bi2–xLaxFe4O9 at small x‐values (x=0.05, 0.1) were synthesized by the solid‐state reaction method. Here larger Bi3+ ions were partially substituted by smaller La3+ ions. It is shown that the above solid solutions had an orthorhombic mullite‐type crystal structures. Crystal lattice parameters of solid solutions were very close to the respective parameters for pure Bi2Fe4O9 ferrite. It was determined that the substitution of Bi3+ ions by La3+ ions in Bi2Fe4O9 leads to the increase of specific magnetizations of the samples. All studied samples were antiferromagnets with Neel temperatures TN of 258 K, 246 K, ∼243 K for x=0, 0.05, 0.1 respectively. Hence at the substitution of Bi3+ ions by La3+ ions, TN decreases. It is shown that solid solution Bi1.9La0.1Fe4O9 had good photocatalytic activity for the oxidation of Acid Telon Blue dye in the aqueous solution under visible light irradiation.

Authors: Sruthi Pambingal Rajan , Roopak Ramakrishnan , Anas Saithalavi 
Published: February 2023

AbstractThis work describes the development of an efficient and reusable heterogeneous polymer supported palladium catalyst for Suzuki reaction in water. This novel catalyst system was designed through monoethanolamine (MEA) modification of nitrile group in Polyacrylonitrile (PAN) followed by metal salt (PdCl2) complexation. The resulting polymer complex (mPAN‐Pd) was then successfully optimised as an efficient heterogeneous catalyst for Suzuki reaction under ligand free conditions. The supported catalyst provided excellent reactivity in the coupling reactions of a series of aryl halides with phenyl boronic acids under mild reaction condition. The reaction proceeded in presence of 2 mol % ofmPAN‐Pdcatalyst at 80 °C in water and the resulting products were isolated in moderate to excellent yields upto 98 %. Furthermore, this catalyst can be conveniently recovered by simple filtration and reused at least five times without an appreciable loss in its activity or Palladium leaching.

AbstractA bis‐heteroleptic Ru(II) complex, 1[PF6]2 of a benzimidazole substituted pyridyl‐1,2,3‐triazole ligand (BiPT) for highly selective luminescence turn‐on detection of hypochlorous acid (HOCl) is reported. Detection of HOCl is achieved by the Markovnikov addition of HOCl to the C=C bond of 1,2,3‐triazole and a successive highly specific C(sp2)‐H chlorination at the C5 position of 1,2,3‐triazole. The chlorination at C5 in 1,2,3‐triazole is supported by high‐resolution mass spectrometry and 1H NMR study. 1[PF6]2 shows high sensitivity towards HOCl in PBS buffer (pH 7.4) containing 5 % acetonitrile with a 37‐fold luminescence light‐up and a detection limit as low as 7.5 μM. HOCl mediated C(sp2)‐H chlorination increases the 3MC‐3MLCT energy gap as well as the population of the 3MLCT excited state and exhibits the radiative decay from the excited state of 1. The probe showed low cytotoxicity and efficiently permeated the cell membrane. The cell‐imaging experiments revealed rapid staining of the HeLa cells in the presence of exogenous HOCl.

Published: February 2023

AbstractThis work focuses on multi‐stimuli‐responsive materials with distinctive abilities, that is, color‐changing and shape‐memory. Using metallic composite yarns and polymeric/thermochromic microcapsule composite fibers, processed via a melt‐spinning technique, an electrothermally multi‐responsive fabric is woven. The resulting smart‐fabric transfers from a predefined structure to an original shape while changing color upon heating or applying an electric field, making it appealing for advanced applications. The shape‐memory and color‐changing features of the fabric can be controlled by rationally controlling the micro‐scale design of the individual fibers in the structure. Thus, the fibers’ microstructural features are optimized to achieve excellent color‐changing behavior along with shape fixity and recovery ratios of 99.95% and 79.2%, respectively. More importantly, the fabric's dual‐response by electric field can be achieved by a low voltage of 5 V, which is smaller than the previously reported values. Above and beyond, the fabric is able to be meticulously activated by selectively applying a controlled voltage to any part of the fabric. The precise local responsiveness can be bestowed upon the fabric by readily controlling its macro‐scale design. A biomimetic dragonfly with the shape‐memory and color‐changing dual‐response ability is successfully fabricated, broadening the design and fabrication horizon of groundbreaking smart materials with multiple functions.

Published: February 2023

AbstractFabrication of single‐crystalline organic semiconductor patterns is of key importance to enable practical applications. However due to the poor controllability on nucleation locations and the intrinsic anisotropic nature of single‐crystals, growth of single‐crystal patterns with homogeneous orientation is a big challenge especially by the vapor method. Herein a vapor growth protocol to achieve patterned organic semiconductor single‐crystals with high crystallinity and uniform crystallographic orientation is presented. The protocol relies on the recently invented microspacing in‐air sublimation assisted with surface wettability treatment to precisely pin the organic molecules at desired locations, and inter‐connecting pattern motifs to induce homogeneous crystallographic orientation. Single‐crystalline patterns with different shapes and sizes, and uniform orientation are demonstrated exemplarily by using 2,7‐dioctyl[1]benzothieno[3,2‐b][1]benzothiophene (C8‐BTBT). Field‐effect transistor arrays fabricate on the patterned C8‐BTBT single‐crystal patterns show uniform electrical performance: a 100% yield with an average mobility of 6.28 cm2 V−1 s−1 and in a 5 × 8 array. The developed protocols overcome the uncontrollability of the isolated crystal patterns in vapor growth on non‐epitaxial substrates, making it possible to align the anisotropic electronic nature of single‐crystal patterns in large‐scale devices integration.
Exploring Individual Differences in Rating Second Language Speech: Rater's Language Aptitude, Major, Accent Familiarity, and Attitudes
Authors: Kahng Jimin 
Published: February 2023

AbstractThis study is the first attempt to explore the relationship between rater variables focusing on raters’ language aptitude and their judgments of second language (L2) speech. Thirty‐four English listeners rated 65 spontaneous native and nonnative speech samples for comprehensibility, accentedness, and fluency. They also completed the LLAMA language aptitude test for associate memory, phonetic memory, sound‐symbol associations, and grammatical inferencing. The results of mixed effect models showed that native listeners’ individual differences (i.e., language aptitude, major, accent familiarity and attitudes) altogether explained 10‐12% of L2 speech ratings. A particularly novel finding is that all aptitude components exhibited significant effects on the ratings. Specifically, associative memory exhibited a positive association whereas and phonetic memory, sound‐symbol associations, and grammatical inferencing had a negative association with the ratings. The findings have a potential to enhance our understanding of the complex dynamics involved in nonnative speech perception and L2 interaction, and implications for researchers and educators in SLA, language assessment, and education.
How is social capital formed and leveraged in international careers? A systematic review and future research directions
Authors: Mathey Friederike , Lysova Evgenia I. , Khapova Svetlana N. 
Published: February 2023

AbstractThe social capital that employees form on international assignments can have important implications for organizational outcomes. However, despite valuable prior research efforts, how and under which conditions international employees’ social capital is formed and translated into benefits for individuals and organizations remains unclear. To address this shortcoming, we employ a systematic literature review methodology and analyze papers on social capital in international careers published in peer-reviewed journals between 1973 and 2022. We integrate our findings into a framework that depicts the micro-, meso-, and macrolevel antecedents that influence the formation of social capital and describe the functional and dimensional features constituting international employees’ (IEs’) social capital. Our review thus outlines how IEs’ social capital is translated into individual and organizational outcomes as well as how it is contingent on several conditions. Based on our proposed framework, we conclude this paper with several suggestions for future research as well as certain practical suggestions for organizations.
Measuring Historic and Longitudinal Social Vulnerability in Disaster-Prone Communities: A Modification to the Centers for Disease Control and Prevention Social Vulnerability Index (CDC-SVI)
Authors: Adepoju Omolola E. , Kiaghadi Amin 
Published: February 2023

Abstract

Objective:
Researchers have developed numerous indices to identify vulnerable sub-populations. The Centers for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI) is the most common and highly serviceable, but it has some temporal limitations considering that some variables used in calculating the CDC-SVI were not available before 1980. Changes in societal composition over time can impact social vulnerability. This study defines an alternate, but similar, index that could serve as a surrogate for the CDC-SVI without the temporal limitations.

Methods:
An inventory analysis of the historical census data (1960-2018) was used to develop a Modified SVI that allows for historic analyses. To consider the chronic effect of social vulnerabilities, a longitudinal SVI was introduced to elucidate how a community’s multidimensional experiences exacerbate vulnerability to disaster events, such as the COVID-19 pandemic. We use Harris County, Texas, in this case study to examine how the Modified SVI performs against the original CDC-SVI.

Results:
This Modified SVI was used to generate historical maps, find temporal patterns, and inform a longitudinal SVI measure. The results showed a good agreement among the developed indices and the CDC-SVI. We also observed satisfactory performance in identifying the areas that are most vulnerable to the COVID-19 pandemic.

Conclusions:
The Modified SVI overcomes temporal limitations associated with the CDC-SVI, and the longitudinal SVI captures a community’s multidimensional experiences that exacerbate a community’s vulnerability to disaster events over time.

Published: February 2023

Abstract

Objective:
The Western Regional Alliance for Pediatric Emergency Medicine (WRAP-EM) is a multi-state, Administration for Strategic Preparedness and Response (ASPR) funded pediatric disaster center of excellence. WRAP-EM set out to determine the impact of health disparities on its 11 core areas.

Methods:
We conducted 11 focus groups during April 2021. Discussions were led by an experienced facilitator, and participants could also include their thoughts on a Padlet throughout the discussion. Data were analyzed to determine overarching themes.

Results:
Responses focused on health literacy, health disparities, resource opportunities, addressing obstacles, and resilience building. Health literacy data highlighted the need for development of readiness and preparedness plans, community engagement in cultural and language appropriate means, and increasing diversity in training. Obstacles faced included funding; inequitable distribution of research, resources, and supplies; lack of prioritization of pediatric needs; and fear of retribution from the system. Multiple already existing resources and programs were referenced highlighting the importance of best practice sharing and networking. A stronger commitment to mental health-care delivery, empowerment of individuals and communities, use of telemedicine, and ongoing cultural and diverse education were recurring themes.

Conclusions:
Results of the focus groups can be used to prioritize efforts to address and improve health disparities in pediatric disaster preparedness.
Sequence entropy tuples and mean sensitive tuples
Authors: LI JIE , LIU CHUNLIN , TU SIMING , YU TAO 
Published: February 2023

AbstractUsing the idea of local entropy theory, we characterize the sequence entropy tuple via mean forms of the sensitive tuple in both topological and measure-theoretical senses. For the measure-theoretical sense, we show that for an ergodic measure-preserving system, the
$\mu $
-sequence entropy tuple, the
$\mu $
-mean sensitive tuple, and the
$\mu $
-sensitive in the mean tuple coincide, and give an example to show that the ergodicity condition is necessary. For the topological sense, we show that for a certain class of minimal systems, the mean sensitive tuple is the sequence entropy tuple.
Tracking the extinct giant Cape zebra (Equus capensis) on the Cape south coast of South Africa

Published: February 2023

AbstractThe giant Cape zebra (Equus capensis) is one of the extinct Quaternary large mammal species of southern Africa, and the largest equid from the Quaternary of Africa. Twenty-six Pleistocene equid tracksites have been identified in aeolianites on the Cape south coast of South Africa. An age range of 161 ± 12 ka to 43 ± 4 ka has been established through Optically Stimulated Luminescence. More than half of the sites contain large-equid tracks, representing the first ichnosites attributed to E. capensis. Smaller equid tracks may have been registered by the quagga (E. quagga quagga). The abundance of E. capensis tracksites on the Cape south coast contrasts with the paucity of body fossils of the species from the region, contrasting with the impression obtained from the body fossil record that E. capensis was predominantly a west coast species in the region. The new data illustrate the capacity of the body fossil and trace fossil records to complement each other. The loss of suitable habitat provided by the Palaeo-Agulhas Plain was probably a contributing factor in the extinction of this large-bodied grazer. A long trackway at Driefontein, attributed to E. capensis, adds to a sparse global record of fossil horse trackways.
Couverture médiatique des enjeux électoraux au Québec de 1994 à 2018
Authors: Martel Marc-Antoine , Nadeau Richard 
Published: February 2023

RésuméCette étude examine l’évolution de la couverture accordée aux enjeux dans la presse écrite durant les campagnes au Québec de 1994 à 2018. Deux constats ressortent de cette étude. On assisterait d'abord à une diversification de l'ordre du jour médiatique s'expliquant notamment par un recul de la question nationale dans l'espace médiatique au profit d'enjeux comme l'environnement et l'immigration. Le recadrage de la question nationale nettement plus axée aujourd'hui sur la dimension identitaire que sur la question du statut politique du Québec est frappant. Ces changements semblent indiquer la montée d'un axe politique libéral-autoritaire dans la province, alors même que l’émergence du multipartisme ouvre la porte à un réalignement politique durable. Ces observations tendent à confirmer la perspective voulant que l'ordre du jour lors d'une campagne résulte de l'interaction entre les médias, les partis et les électeurs et qu'il offre ainsi un reflet adéquat de l’évolution de la dynamique politique dans une société donnée.
Evaluation of an indwelling bolus equipped with a triaxial accelerometer for the characterisation of the diurnal pattern of bovine reticuloruminal contractions
Authors: Capuzzello Giovanni , Viora Lorenzo , Borelli Elena , Jonsson Nicholas N. 
Published: February 2023

AbstractThis observational study aimed to describe the diurnal pattern of reticuloruminal contraction rate (RRCR) and the proportion of time spent ruminating by cattle, using two commercial devices equipped with triaxial accelerometers: an indwelling bolus (placed in the reticulum) and a neck collar. The three objectives of this study were firstly to determine whether the indwelling bolus provided observations consistent with RRCR as determined by clinical examination using auscultation and ultrasound, secondly to compare estimates of time spent ruminating using the indwelling bolus and a collar-based accelerometer, and finally to describe the diurnal pattern of RRCR using the indwelling bolus data. Six rumen-fistulated, non-lactating Jersey cows were fitted with an indwelling bolus (SmaXtec Animal Care GmbH, Graz, Austria) and a neck collar (Silent Herdsman, Afimilk Ltd. Kibbutz Afikim, Israel), and data were collected over two weeks. Cattle were housed together in a single straw-bedded pen and fed ad libitum hay. To assess the agreement between the indwelling bolus and traditional methods of assessing reticuloruminal contractility in the first week, the RRCR was determined over 10 min, twice a day, by ultrasound and auscultation. Mean inter-contraction intervals (ICI) derived from bolus and ultrasound, and from auscultation were 40.4 ± 4.7, 40.1 ± 4.0 and 38.4 ± 3.3 s. Bland–Altmann plots showed similar performance of the methods with small biases. The Pearson correlation coefficient for the time spent ruminating derived from neck collars and indwelling boluses was 0.72 (highly significant, P < 0.001). The indwelling boluses generated a consistent diurnal pattern for all the cows. In conclusion, a robust relationship was observed between clinical observation and the indwelling boluses for estimation of ICI and, similarly, between the indwelling bolus and neck collar for estimating rumination time. The indwelling boluses showed a clear diurnal pattern for RRCR and time spent ruminating, indicating that they should be useful for assessing reticuloruminal motility.
