Arab EFL Learner Perceptions of English Phonemes: A Cross-Language Phonetic Interference
Authors: Al-Kinany Taif , Al-Abri Abdullah , Ambusaidi Hafid
Published: January 2022

The extant studies addressing second language phonetic perception assume that second language phonemes are perceived to be similar to first language phonemes, and tend to be substituted by learners of English as a foreign language. This study aimed to assess the perceptual relationship between the phonemes of English and the sound units of Omani Arabic of the Al-Dakhiliyah region to discover the extent of the influence exerted by Omani Arabic on the perception of English phonemes by Omani learners. Two instruments were constructed to achieve this goal: first, the Omani phonetic system was elucidated via a questionnaire and the consonants and vowels uttered by the Omani people were archived as a phonetic dialect; second, a test was created to examine the perceptual phonetic distance between Omani Arabic and English phonemes. This investigation was designed to test the hypothesis of the revised speech learning model. The results confirmed the model’s postulation that learners instinctively and reflexively associate the second language sounds to the phonetic groups of their first language.
The Use of Metadiscourse by Saudi and British Authors: A Focus on Applied Linguistics Discipline
Authors: Binmahboob Thamer
Published: January 2022

This study investigated the use of metadiscourse tools by Saudi and British authors in Applied Linguistics discipline. In particular, the study tried to identify the kinds of metadiscourse markers used by Saudi and English authors in ALRAs and to determine the most and least frequent metadiscourse makers. In order to achieve these goals, (10) ALRAs written by Saudi authors and (10) ALRAs written by British authors served as the corpus of the study. The research articles were selected from well-known journals and published between 2010 – 2018. Hyland's (2005) model was used to find out the distribution of metadiscourse markers in each type of corpora. The findings showed interactive metadiscourse markers are used more than the interactional metadiscourse markers. Compared with the British authors, the Saudi authors were found to use metadiscourse markers more than the British authors. The Saudi authors employed all metadiscourse sub-categories more frequently than the British authors except frame markers, evidentials, endophoric markers, and self-mentions. In addition, it was found that transitions were the highly frequent metadiscourse markers in the whole corpora, followed by hedges, evidentials, boosters, and attitude markers, respectively. On the other hand, engagement markers were the least frequent metadiscourse markers in the whole corpora. 
Mediation Effect of Knowledge Sharing Quality on Employee Creativity
Authors: Doronin Dimitry , Lei Shen , HAMAD HASSAN Shan SYED
Published: January 2022

Employee creativity requires knowledge sharing, according to many experts. What aspects of the knowledge sharing cycle encourage employee creativity? In this study, authors examined three factors, i.e., ‘opportunity for exchange (OFE), value anticipation (VA), and motivation to engage (MTE)’, that influence the production of intellectual capital (as antecedents) and its effects on employee creativity (as outcomes) through knowledge sharing (KS) and quality of knowledge sharing (QKS: as mediating mechanism). To test the hypothesized relationships, Mplus was used to analyze 371 Russian IT employees. The findings suggest that OFE, VA and MTE are important antecedents of both KS and QKS. Moreover, KS and QKS mediates the relationship between antecedents (OFE, VA and MTE) and outcome variable (employee creativity). Theoretical contribution and future research are discussed.

Authors: Pajokh Mojde , Mehralizadeh Akbar , Dalfardi Mahsa , Seyedi Fatemeh
Published: January 2022

Background: Stature and sex estimation according to surface anatomical landmarks is applicable for personal identification in forensic medicine. Objectives: The present study aimed to prepare a comprehensive reference of four main upper limb anthropometric dimensions in Iranian adults and make a formula for predicting sex and stature according to them. Methods: In this cross-sectional study, four main anthropometric dimensions of the upper limb, including arm length, forearm length, hand length, and hand width of 280 Iranian adults aged 20 - 24 years, were measured according to surface anatomical landmarks. To determine sex differences, we divided the collected measures into two groups: (1) study (120 males and 120 females); and (2) test (20 males and 20 females) groups. Sexual dimorphism indicator and discriminant functions were conducted on the study group and were validated according to the test group. The relativity of stature with measured dimensions was done by a simple linear regression test in the male and female groups. Results: All upper limb measurements were potent to determine gender, but forearm length displayed the highest accuracy of 94.2 - 95% and 95 - 100% for the study and test groups, respectively. Regression analysis revealed that arm length had the highest correlation with stature (22.2% for males and 18.41% for females). Conclusions: We prepared a sex and stature estimation formula based on four upper limb anthropometric dimensions in Iranian adults that can be used in the forensic and clinical fields.

Verificación: ¿la cuadratura del círculo contra la desinformación y las noticias falsas?
Authors: Tuñón Navarro Jorge , Sánchez del Vas Rocío
Published: February 2022

En las últimas décadas, la desinformación se ha visto multiplicada exponencialmente dentro del panorama informativo. Sin embargo, la pandemia de la COVID-19 ha dado un vuelco a la situación, volviéndola crítica. Las noticias falsas se han tornado un verdadero problema para la salud pública, diseminándose más rápido incluso que la información verdadera. En este sentido, para luchar contra la desinformación, se han consolidado diversas iniciativas de fact-checking por todo el mundo, en particular, tras la crisis sanitaria. Por su parte, la Unión Europea es una de las organizaciones más expuestas a las noticias falsas. Es por ello por lo que cuenta con diversos actores para hacerle frente. Igualmente, España también presenta varias experiencias de verificación de noticias. Por otra parte, las empresas tecnológicas juegan también un papel clave y algunas de ellas ya han comenzado a implementar mecanismos contra la pandemia de bulos. No obstante, la verificación de datos se encuentra bajo debate ante la posibilidad de que esta produzca un efecto inverso (backfire effect). Ante ello, se ha llevado a cabo un estudio documental bibliográfico de investigaciones precedentes, combinado con un análisis cualitativo no experimental de los resultados obtenidos. El objetivo del mismo ha sido comprender el fenómeno del fact-checking, su evolución y características con el fin de analizarlo como potencial solución final a la desinformación. A partir de esta investigación, se busca la retroalimentación desde la academia científica/universitaria con el objetivo de ampliar su conocimiento sobre el fenómeno desinformativo. Por tanto, los resultados de esta investigación cuentan con una clara vocación de servicio público (europeo).
Effect of thermal conduction on Kelvin-Helmholtz instability in straight pipe with different cross-sections
Authors: Cao Yi-Gang , Fu Meng-Meng , Yang Xi-Chang , Li Deng-Feng , Wang Xiao-Xia ,   School of Physics, Zhengzhou University, Zhengzhou 450001, China
Published: February 2022

We investigate analytically the effect of thermal conduction on the Kelvin-Helmholtz instability (KHI) in a straight pipe with different cross-sections. The results show that the relative tangential velocity of the interface between the upper and lower fluid in the pipe first increases and then decreases with the increase of the wave number. Furthermore, the smaller coefficient of interfacial heat conduction causes the relative tangential velocity to decrease considerably with the increase of the wave number, which is different from the behavior of the straight pipeline with the same cross-section. In addition, the heat conduction increases the growth rate of KHI, which is in accordance with the scenario of straight pipeline with the same cross-section.

Published: February 2022

In this paper, photoelectron interference in tunneling ionization of atoms by counter-rotating two-color elliptically polarized (TCEP) laser fields are investigated by numerically solving the two-dimensional time-dependent Schrödinger equation (TDSE) and strong field approximation (SFA). When the ellipticities of the two pulses are both 0.3, for a relative phase of 0.25π, the intracycle interference, fork-like holographic interference and arc-like holographic interference in the photoelectron momentum distribution overlap with each other. For a relative phase of 0, the arc-like holographic interference disappears and the intracycle interference and fork-like holographic interference are fully separated into the –px direction and the +px direction. Furthermore, the independent fork-like holographic interference can be enhanced or suppressed by changing the ellipticities of the two pulses. This provides an efficient tool for controlling and separating the interference structures in the photoelectron momentum distribution, which facilitates extracting the information about the target structure and the photoelectron ultrafast dynamics in strong fields.

Terahertz metamaterial biosensor is a label-free affinity sensor that enhances the strength of the local electromagnetic field. It is extremely sensitive to changes in the dielectric constant of the surrounding environment, thereby providing a new method of detecting micro or trace biological samples. In this work, a highly sensitive terahertz refractive index metamaterial absorber sensor for detecting the biological sample is proposed. The sensor consists of two concentric open metal rings and is a multimode resonator. With two independent adjustable operating bands in a frequency range of 0.7–2.5 THz, i.e. 1.079 THz and 2.271 THz, the sensor can observe different electromagnetic effects of the sample in the terahertz band. We evaluate the performance of terahertz sensors with indicators such as absorption characteristics and sensitivity. The sensor possesses the absorption higher than 99.9% in free space. In addition, the large Q value indicates that the sensor provides high frequency selectivity characteristics. Especially, the sensitivity of the sensor achieves 693.7 GHz/RIU, with a minimum refractive index change of 0.004 for the detection of biological samples, which provides good sensing performance. In the proposed sensor, a flexible material with low dielectric constant is used, which has the advantages of biocompatibility and portability and shows high stability at the 0°–60° oblique incidence angle and within 4% fabrication error. Moreover, the detection effectiveness of the sensor is verified by simulation experiments with ethanol-water mixtures. The sensor units designed in this paper have small interactions among them, work stably and are easily fabricated The sensor can significantly enhance the interaction between light and matter and has broad application prospects in terahertz high-sensitivity biosensing detection.

La exposición a riesgos psicosociales y violencia laboral se asocia con una mayor presencia de problemas de salud mental en los/as trabajadores/as. El presente estudio tuvo como objetivo indagar el rol mediador de la violencia laboral entre los riesgos psicosociales (ISOSTRAIN, desbalance esfuerzo-recompensa), antecedentes organizacionales (liderazgo tiránico) y problemas de salud mental (distrés) en 1023 trabajadores/as de tres hospitales públicos chilenos de alta complejidad de tres regiones del país. Se hipotetizó que la exposición a riesgos psicosociales y algunas características organizacionales (liderazgo tiránico) se asocia a menores niveles de salud mental y que parte de este efecto se encuentra mediado por la exposición a violencia laboral. Se aplicó un cuestionario incluyendo el Negative Act Questionnaire Revised (NAQ-R), el Screening de Distrés Psicológico, la Escala de Liderazgo Destructivo, el Cuestionario de Desbalance Esfuerzo-Recompensa y el Job Content Questionnaire. Mediante análisis de senderos, se observó que la exposición a riesgos psicosociales, liderazgo tiránico y violencia laboral aumenta los niveles de distrés de los/as trabajadores/as. Parte del efecto de los riesgos psicosociales y el liderazgo tiránico en la salud mental se encuentra mediado por la exposición a violencia laboral. El artículo termina discutiendo la necesidad de avanzar en protocolos y prevención de riesgos psicosociales y violencia laboral, en particular en el contexto del trabajo en salud pública.

Factors Affecting School Teachers' Satisfaction with Online Classes during the Outbreak of COVID-19
Authors: Falah Alfalahat Fatima Mosleh
Published: January 2022

Many research studies have been conducted to understand the end-users satisfaction with online teaching. Yet, there are scarce studies focused on the teachers' satisfaction with online classes. This research aims to study factors affecting teachers' satisfaction with online teaching systems. To this purpose, an extended Technology Acceptance Model (TAM) is proposed in this study. The possible correlation among variables and whether or if there are gender disparities were also examined. An online questionnaire was deployed using Google forms, and 330 teachers filled out the questionnaire. Structural Equation Modeling (SEM) was used to conduct the path analysis and test hypotheses. A multi-group analysis was conducted to investigate whether gender was related to teacher satisfaction with online education. There were three key results. First, perceived usefulness, ease of use, and self-efficacy directly influenced teachers' satisfaction with online teaching. Second, personal innovativeness indirectly impacted teachers' satisfaction through perceived usefulness and perceived ease of use. Third, gender did not affect the eight hypotheses. This research has theoretical implications since it contributes to the study of online education satisfaction by extending the TAM model to examine the factors affecting teachers' satisfaction with online teaching. This research also has practical implications in that it may be used as a reference for school administrators, online learning system designers, and decision-makers.

Cotton, known as “the King of fibers”, is the predominant fiber in the Indian textile industry. Plant growth-promoting rhizobacteria (PGPR) represent a potential sustainable alternative for the enhancement and protection of crops. The germination and seedling growth of cotton can be optimized by inoculating with PGPR. An experiment was conducted to evaluate the effect of different PGPR strains on seed germination and seedling establishment characters on cotton. The highest germination percentage, maximum vigour index and leaf area was obtained with the PPFM TNAU1 strain inoculation. The maximum shoot and root length were observed with seeds treated with Azospirillum strain sp7 with an increase of 24.4 and 42.8% over the control. Underground fresh and dry matter was higher in seedlings treated with Azospirillum sp7 strain compared to control, while the PPFM TNAU1 strain treatment increased the aerial fresh and dry matter content because of its larger leaf area. Seeds inoculated with individual strain of Azospirillum sp7 and PPFM TNAU1 outperformed the combined inoculation of PGPR strains. The increase in germination traits and seedling characters by PGPR strains indicates the positive influence on improving cotton seedling establishment traits associated to higher yield.

A Brief Review on Postpartum Depression
Authors: Dange Vaishnavi , Biswas Dalia
Published: February 2022

Postpartum depression is a medical condition in which a woman faces mental issues after delivery. Postpartum depression is associated with anxiety, mood swings, tiredness, feeling scared all the time, trouble sleeping or sleeping, weight loss, stress eating, losing interest, sudden weight gain, and difficulty concentrating or making decisions, fatigue and several other issues. It can happen during pregnancy as well as after giving birth. Some women experience baby blues while some experience postpartum depression. Women feel depressed and sadly most of the time. Depression can make it difficult for mother to take care of herself and the child. Various lifestyle choices also need to be mentioned while talking about factors causing PPD. Some factors affecting PPD are lack of physical activity and exercise, bad eating habits, disturbed sleep cycle etc. it may include hormonal changes, sleep deprivation, risk factors, psychological stress. One of the chief factors affecting postpartum depression is the sleep cycle. It is seen that less sleep is brought near to postnatal depression. Exercise, psychosocial support, physical stretching or working activity can decrease symptoms of depression. Exercise causes the release of mood-boosting hormones such as dopamine and serotonin, which elevates the mood. Low esteem caused by depression can be decreased by an elevated mood. Exercise can also increase endogenous endorphins and opioids which gives a positive mood. It also increases problem solving capacity and confidence. The most common management methods used for managing depression are psychological support, professional help, interpersonal psychotherapy and cognitive therapy.

Via methods of compression, vacuum, supercritical, and so on, foams can obtain reentrant cells and NPR properties, but they may suffer mass‐ or heat‐transfer gradient, causing uneven cells and performance. 3D printing technology can fabricate uniform NPR structures, whereas the common 3D‐printed concave shapes own downward concave points that should be supported, and removing the support materials complicates the preparation severely. Thus, to propose a facile method for building NPR structures, a 3D‐repeating tetrahedron‐framework with 2D NPR origami facets is designed. One edge of the tetrahedron is designed to be vertical, and thus all the facets are not horizontal. Then, the concave points on the facets are obliquely downward instead of totally downward so that the framework can be 3D‐printed without support. The Poisson's ratio of that structure is controlled from −0.8 to 0.4 via adjusting the facet thickness, and the mechanism is confirmed by differential geometry calculation and finite element analysis. Notably, improvement in specific modulus is found in different materials with that structure, and the support‐free 3D printing strategy can further be used to design customized shapes (such as lightweight aerial vehicle devices and NPR soles here).

This investigation concerns the application of the profilometry‐based indentation plastometry (PIP) methodology to obtain stress–strain relationships for material in the vicinity of fusion welds. These are produced by The Welding Institute (TWI), using submerged arc welding to join pairs of thick steel plates. The width of the welds varies from about 5 mm at the bottom to about 40–50 mm at the top. For one weld, the properties of parent and weld metal are similar, while for the other, the weld metal is significantly harder than the parent. Both weldments are shown to be approximately isotropic in terms of mechanical response, while there is a small degree of anisotropy in the parent metal (with the through‐thickness direction being slightly softer than the in‐plane directions). The PIP procedure has a high sensitivity for detecting such anisotropy. It is also shown that there is excellent agreement between stress–strain curves obtained using PIP and via conventional uniaxial testing (tensile and compressive). Finally, the PIP methodology is used to explore properties in the transition regime between weld and parent, with a lateral resolution of the order of 1–2 mm. This reveals variations on a scale that would be very difficult to examine using conventional testing.

High entropy alloys (HEAs) represent a new class of advanced metallic alloys that exhibit unique structural features and promising properties. The potential benefit of HEAs, in conjunction with established thermal spray manufacturing technologies, can provide a practical approach to mitigate wear and corrosion. Equiatomic AlCoCrFeMo HEA were fabricated using cold‐spraying and flame‐spraying, aiming to investigate the effect of low‐temperature and high‐temperature responses to phase formations, microstructural evolution, and microhardness. The performance evaluation during abrasive damage and electrochemical corrosion were also investigated. Microstructural studies revealed that coatings with body‐centered cubic (BCC) phases, where oxides were found in the flame‐sprayed coatings during in‐flight deposition. Hardness of the flame‐sprayed coatings showed noticeably (5.78 ± 0.45 GPa) higher than to that of the cold‐sprayed coatings (3.6 ± 0.48 GPa). Lower wear rates were achieved for the flame‐sprayed coatings (compared to the cold‐sprayed coatings. Oxide formations in the flame‐sprayed coatings decreased its corrosion performance such that it was two times lower than that of cold‐sprayed coatings. The results show that the microstructural features of flame‐sprayed coatings, coupled with formation of oxide inclusions resulted in improved resistance to damage due to wear loading, but undermined resistance to electrochemical degradation.

Tailorable electron distribution of the active sites is widely regarded as the key issue to boost the catalytic activity and provide mechanistic insights into the structure–property–performance relationship. Here, a selective metal atom in situ growth strategy to construct highly active interface of mixed metal atom with different NbyRhOx species on sp‐/sp2‐cohybridized graphdiyne (NbyRhOx/GDY) is reported. With this innovative idea implemented, experimental results show that the asymmetric electron distribution and the variation of coordination environment of bimetallic species significantly improve the electrocatalytic activity of NbyRhOx/GDY. Optimal hydrogen evolution reaction (HER) activity is achieved at the Nb/Rh ratio of 0.23, exhibiting excellent HER activity with the small overpotentials of 14 and 10 mV at 10 mA cm−2 in alkaline and neutral electrolytes. The data show the strong potential for real‐system application of such catalysts, which outperform commercial Pt/C (20 wt%). These results shown in this study represent a platform for designing novel catalytic materials by selectively introducing metal atoms on different supports, which can be used as a general method extended to other catalytic systems.
A dynamic by‐production framework for measuring productivity change in the presence of socially responsible and undesirable outputs: Evidence from European food processors

In the past decade, corporate firms have globally increasingly adopted corporate social responsibility (CSR) practices; however, so far less is known about how productivity change in the presence of socially responsible and undesirable output can be evaluated. This paper develops a framework that integrates CSR in a dynamic by‐production technology which captures the transformation of multiple inputs into marketed outputs, socially responsible and undesirable outputs, while accounting for adjustment costs in quasi‐fixed inputs. The paper illustrates the method using a sample of European food and beverage manufacturing firms. The results of the empirical application show that there is a decline in dynamic Luenberger productivity indicators mainly due to technical inefficiency change. Hence, firms should devise strategies to enhance utilization of resources and reduce technical inefficiency. The regression of productivity change indicators on firm‐specific factors showed that more indebted firms experienced a lower growth of the productivity of undesirable output, whereas more profitable firms have a lower productivity growth of variable inputs and a higher growth of the productivity of investments.

Time‐to‐completion for mergers and acquisitions in the food and agribusiness industry
Authors: Adelaja Adesoji O. , Mukhopadhyay Ramyani
Published: February 2022

Longer time‐to‐completion (TTC) increases transaction costs, delays deal benefits, and reduces the probability of meeting transaction objectives in mergers and acquisitions (M&A) transactions. This paper conceptualizes the determinants of TTC and estimates their effects in the food and agribusiness industry (FABI) due to the critical importance of TTC to M&A success and the dearth of existing studies on the industry. We confirm that longer TTC increases the likelihood of deal failure. We also find the following: company‐specific factors such as acquirer solvency and leverage reduce TTC; deal complexity factors such as deals involving payment in cash or hard currency conclude faster; deals involving both acquirers and targets from the same country or industry take longer; using legal or financial advisers lengthens TTC; limited transparency or greater risk involved in a deal do not delay financing; deals consumed during a recession take longer; deal size and acquirer history of repeated M&A activities neither accelerate nor delay TTC. Considering the limited existing information on the contributions of various factors to timely deal completion or delays in FABI, our findings are useful in predicting M&A deal duration, costs, and potential for success.

Assessment of liquid–liquid equilibrium data by solving the Gibbs‐Duhem equation
Authors: Fernández Luís , Ortega Juan , Wisniak Jaime
Published: February 2022

A methodology, based on the Gibbs‐Duhem equation, is developed to study the thermodynamic consistency of liquid–liquid equilibrium (LLE) data. The method proposes evaluating the experimental data in two ways: (a) integral‐form, verifying dependences among variables in the same phase, both for temperatures: , and compositions: , and (b) differential‐form, which validates relationships between the compositions of each phase by . A coverage factor κ is introduced in both approaches to define the degree of confidence of the evaluation using a database (T, ) of 50 binary systems to define the limits of inconsistency. With κ = 3, more than 60% of the set is accepted (κ > 3 falls to 38%) providing a guarantee of quality for LLE data. The results show that the consistency test can detect errors in the set {data + model} under study, although the absence of a reference state for the LLE gives the model a limited sensitivity to systematic errors.
