The pandemic has dramatically changed the reality not only for certain countries but the whole	world: frightened by the virus, people got locked at homes, countries, and companies started working online. Nowadays, due to the economic crisis resulted from the corona virus, new opportunities have emerged and	the society has imposed new requirements to the creativity, in particular, doctors and scientists are demanded	to discover the Covid-19 vaccine, while the economists have to save the country from the economic crisis. Therefore, creative people with different thinking minds, a non-standard approach to the topics, and	implementation of the innovations are necessary to find a way out of this hard situation.
As a result of the pandemic, people have limited contacts with each other, while communications	between organizations and governments have increased, most of them started working online pushing the companies to move in a new step of the development – digital transformation. The virus has created a range	of new opportunities for the countries together with multiple challenges.

Effectiveness of Metacognitive Instruction on Students’ Science Learning Achievement: A Meta-Analysis
Authors: Antonio Ronilo , Prudente Maricar 
Published: April 2021

This study examined the effectiveness of metacognitive instruction on science learning achievement using a meta-analytic procedure. Statistical analyses were performed using the software Comprehensive Meta-Analysis (CMA) Version 3 developed by Biostat, Inc. Based on the findings, the overall effect size (ES=0.808) revealed that the use and integration of metacognition in science instruction has a significantly large and positive effect on student learning achievement. Moderator analysis showed that there was a significant difference in the effect sizes of the individual studies when grouped according to the student’s level of education and the scientific disciplines being studied. However, the obtained positive and large effect sizes suggested that the use and integration of metacognition can be effectively implemented whether students are in the elementary, secondary or tertiary level, be it Biological or Physical Science. Moreover, the metacognitive strategies employed by individual studies are mostly found to be integrated with ICT mainly metacognitive prompts; other practices were student-led metacognitive discussions, concept mapping, metacognitive writing, and metacognitive practice and training. This result establishes the effectiveness of the use and integration of different metacognitive strategies to improve student learning. Thus, science teachers must be equipped with pedagogical knowledge on the implementation and integration of metacognition in classroom instruction.

Early sexual debut is common in Nigeria and increases HIV risk among adolescents. About 152,000 adolescents are living with HIV. Lack of knowledge and appropriate sexual reproductive health services are some factors responsible. This paper estimated the cost of secondary school-based HIV/AIDS intervention for schools in Enugu State, Nigeria. The rationale for estimation is to avoid unaffordable and ineffective interventions. The cost was estimated between March to October 2019 for schools in urban and rural areas with a population of 1595 students. The cost estimation was aided through UNAID proposed guideline. The estimation was done by classifying the intervention into the cost of training, cost of services and cost of commodities. The cost was estimated at $5954. The estimated cost in the urban is lesser than that of rural.

Published: April 2021

The employee’s in-role and extra-role performance has badly effected due to prevalence of COVID-19. The aim of the study is to examine the relationship of perceived organizational support and employee performance. The role of organizational justice is examined as a moderator. A sample of 222 bank employees was selected on convenience basis. The responses were recorded through closed ended questionnaires. The responses were analyzed through Partial Least Square Structural Equation Modeling Method. In times of COVID-19 the perceived organizational support has an antidotal effect on employee’s performance. At the same time the organizational justice has a significant role in the relationship of perceived organizational support and employee performance. The managers interested to have good performance of employees have to ensure organizational support along with justice in organizational practices. The perceived organizational support and justice induce trust among employees and compel them to work with diligence. The organizational justice has greater contributions towards performance. The study has examined the non-linear relationship between perceived organizational support and employees’ performance in bank employees in the context of COVID-19. In such times the people expect increased need for organizational support to fight out the challenges

AbstractVacancies created on a surface can alter the local electronic structure, thus enabling a higher intrinsic activity for the evolution of hydrogen and oxygen. Conventional strategies for vacancy engineering, however, have a strong focus on non‐metal sulfur/oxygen defects, which have often overlooked metallic vacancies. Herein, evidence is provided that cobalt vacancies can be atomically tuned to have different sizes to achieve cobalt vacancy clusters through controlling the migration of iridium single atoms. The coalescence of Co vacancy clusters at the surface of an IrCo alloy results in an increased d‐band level and eventually compromises H adsorption, leading to enhanced electrocatalytic activity toward the hydrogen evolution reaction. In addition, the Co vacancy clusters can improve the electronic conductivity with respect to the oxidized Co surface, which substantially aids in strengthening the adsorption of oxygen intermediates toward an effective oxygen evolution reaction at a low overpotential. These collective effects originate from the Co vacancy cluster and specifically enable highly efficient and stable water splitting with a low total overpotential of 384 mV in alkaline media and 365 mV in an acidic environment, achieving a current density of 10 mA cm–2.

AbstractOwing to the moderate energy offset between light and heavy band edges of the rock‐salt structured GeTe, its figure‐of‐merit (ZT) can be enhanced by the rational manipulation of electronic band structures. In this study, density functional theory calculations are implemented to predict that V is an effective dopant for GeTe to enlarge the bandgap and converge the energy offset, which suppresses the bipolar conduction and increases the effective mass. Experimentally, V‐doped Ge1−xVxTe samples are demonstrated to have an enhanced Seebeck coefficient from ≈163 to ≈191 µV K−1. Extra alloying with Bi in Ge1−x−yVxBiyTe can optimize the carrier concentration to further enhance the Seebeck coefficient up to ≈252 µV K−1, plus an outstanding power factor of ≈43 µW cm−1 K−2. Comprehensive structural characterization results also verify the refinement of grain size by V‐doping, associated with highly dense grain boundaries, stacking faults, nanoprecipitates, and point defects, reinforcing the wide‐frequency phonon scattering and in turn, securing an ultralow thermal conductivity of ≈0.59 W m−1 K−1. As a result, the Ge0.9V0.02Bi0.08Te sample shows a peak ZT of >2.1 at 773 K, with an average plateaued average ZT of >2.0 from 623 and 773 K, which extends better thermoelectric behavior for GeTe over a wider temperature range. This study clarifies the multiple benefits of V‐doping in GeTe‐based derivatives and provides a framework for a new‐type of high‐performance middle‐temperature thermoelectric material.
Simultaneously Harvesting Friction and Solar Energy via Organic/Silicon Heterojunction with High Direct‐Current Generation

Published: April 2021

AbstractThe direct‐current triboelectric nanogenerator (TENG) is a promising portable energy source that can power mobile electronics without any rectification circuits. Recently, the silicon‐based TENGs, as a rectification‐free power source, have drawn wide attention due to their high current‐density outputs. However, the performance of silicon‐based TENGs is still inferior owing to a low amount of carrier generation and poor efficiency of carrier collection. Here, a strategy is proposed to improve the performance of metal/silicon TENGs via building an alternative device structure consisting of a transparent conductive polymer interlayer. This transparent interlayer can passivate surface defects as well as enhance carrier extraction, enabling a simultaneous harvest of friction and solar energy. More importantly, the gain effect of friction‐induced electric field occurs, which significantly surges the power output efficiency. As a result, the device yields a record output performance with an output voltage over 1000 mV and an output current up to 6.0 × 103 A m‐2 under 20 mW cm‐2 white light illumination. This research not only promises an alternative energy source device that can harvest both mechanical and solar energy but also paves the way to separate photo‐generated carriers with a friction‐induced electric field.

AbstractIn this study, the graphite effect on the mechanical and fire‐retardant performance of low‐density polyethylene (LDPE) and ethylene‐vinyl‐acetate (EVA) foam composites was investigated. Polymer composites were prepared by melt mixing process and foamed by hot press molding at different graphite content (0, 3, 6, and 12 phr). Cone calorimetric tests through heat release rate (HRR) curves obtained, revealed a decreasing of 45% on peak heat release rate (pHRR) of foam composites LDPE‐EVA with 12 phr of untreated graphite content compared than those LDPE‐EVA foamed composites without graphite, which was attributed to the good distribution of graphite in the composite and more residual generates as thermogravimetric analysis suggested. Mechanical properties of polymer foamed composites with high graphite content do not show significant detrimental as a result to the formation of more uniform cells with smaller size incorporating a material with high modulus like graphite. The results suggest that polymer foam composites with graphite are suitable for the building and construction industry, in sealing and thermal insulation applications with good fire‐retardant performance.

AbstractThe social distancing measure imposed worldwide to combat the outbreak of the novel coronavirus has seen rapid adoption of technologies to support online education. Compared to traditional lecture‐based courses, online teaching is particularly more challenging for laboratory courses where hands‐on activities are essential to achieve the learning outcomes. To deal with this issue, the study presented in this paper was aimed to: (1) to develop a virtual reality (VR) application to aid a civil engineering laboratory course, and (2) to measure the potential of the VR‐aided learning (VRAL) application in civil engineering education by assessing the learners' preferences toward VRAL compared to instructor‐aided learning (IAL) and video‐aided learning (VAL). Using the Analytic Hierarchy Process, a comparison was conducted with 21 civil engineering students from both undergraduate and graduate levels. The results indicated that VRAL was more preferable than VAL by the participants based on the aspects of “interactivity” (the ability to provide theoretical and practical learning environments to the learners), “cognitive interest” (the ability to drive learners to engage in learning activity), “ease of understanding the content” (the ability to provide a clear lecture interpretation, i.e., easy to understand), and “support for learning” (the ability to help learners to achieve the learning goal). Although VRAL was comparatively less preferable than IAL by the participants overall, it was viewed as better in terms of cognitive interest and “accessibility” (the ability to provide learners with better access to the learning approach in terms of time and location). Complementing previous research, the findings supported the benefits of VR applications to aid civil engineering education.

Published: April 2021

BackgroundAssessing patient and caregiver experiences with care is central to improving care quality. The authors assessed variations in the experiences of advanced cancer patients and their caregivers with physician communication and care coordination by patient and caregiver factors.MethodsThe authors surveyed 600 patients with a stage IV solid malignancy and 346 caregivers every 3 months for more than 2 years. Patients entered the cohort any time during their stage IV trajectory. The analytic sample was restricted to patient‐caregiver dyads (n = 299). Each survey assessed patients' experiences with physician communication and care coordination; patients' symptom burden; caregivers' quality of life; and patients' and caregivers' anxiety, financial difficulties, and perceptions of treatment goals. An actor‐partner interdependence framework was used for analysis.ResultsPatients reported better physician communication (average marginal effect [AME], 6.04; 95% confidence interval [CI], 3.82 to 8.26) and care coordination (AME, 8.96; 95% CI, 6.94 to 10.97) than their caregivers. Patients reported worse care coordination when they (AME, –0.56; 95% CI, –1.07 to –0.05) or their caregivers (AME, –0.58; 95% CI, –0.97 to –0.19) were more anxious. Caregivers reported worse care coordination when they were anxious (AME, –1.62; 95% CI, –2.02 to –1.23) and experienced financial difficulties (AME, –2.31; 95% CI, –3.77 to –0.86). Correct understanding of the treatment goal (vs being uncertain) was associated with caregivers reporting physician communication as better (AME, 3.67; 95% CI, 0.49 to 6.86) but with patients reporting it as worse (AME, –3.29; 95% CI, –6.45 to –0.14).ConclusionsPatients' and caregivers' reports of physician communication and care coordination vary with aspects of their own and each other's well‐being and with their perceptions of treatment goals. These findings may have implications for improving patients' and caregivers' reported experiences with health care practitioners.

Published: April 2021

SummaryCondition monitoring and fault diagnosis of main bearings of large‐scale wind turbines is critical for improving its reliability and reducing operating and maintenance costs, especially in the early stages. To achieve the goal, this paper proposes a novel deep learning approach named stacked sparse autoencoder multi‐layer perceptron (SSAE‐MLP) with a new framework by utilizing supervisory control and data acquisition (SCADA) data for wind turbine main bearing temperature prediction. After the SCADA parameter variables related to the temperature change of the main bearing are extracted, the input characteristic vector is constructed. Then, the multiple sparse autoencoders are stacked to learn the deep features inside the input data by applying the greedy layerwise unsupervised learning algorithm. Finally, a regression predictor is added to the top layer of the stacked sparse autoencoder model for supervised learning to fine‐tune the overall network. Comparative experiments show that the proposed approach has superior performance for wind turbine main bearing temperature prediction.

Published: April 2021

The objective of this study was to determine the effects of the OATP inhibitor rifampin on pharmacokinetic of Biopharmaceutics Drug Disposition Classification System Class 1 compound fluvastatin. A crossover study was carried out in 10 healthy subjects who were randomized to 2 phases to receive fluvastatin 20 mg orally alone and following a 30‐minute 600 mg i.v. infusion of rifampin. The results demonstrated that i.v. rifampin increased the mean area under the plasma fluvastatin concentration–time curve (AUC0–∞) by 255%, mean peak plasma concentration (Cmax) by 254%, decreased oral volume of distribution by 71%, whereas the mean elimination terminal half‐life (T1/2), mean absorption time (MAT), and time to peak concentration (Tpeak) of fluvastatin did not significantly change. The study demonstrated that rifampin exhibited a significant drug interaction with fluvastatin. The mechanism of the increased plasma concentrations is likely due to inhibition of OATP transporters in hepatocytes.
