The effectiveness of collaborative problem solving in promoting students’ critical thinking: A meta-analysis based on empirical literature
Authors: Xu Enwei , Wang Wei , Wang Qingxia 
Published: January 2023

AbstractCollaborative problem-solving has been widely embraced in the classroom instruction of critical thinking, which is regarded as the core of curriculum reform based on key competencies in the field of education as well as a key competence for learners in the 21st century. However, the effectiveness of collaborative problem-solving in promoting students’ critical thinking remains uncertain. This current research presents the major findings of a meta-analysis of 36 pieces of the literature revealed in worldwide educational periodicals during the 21st century to identify the effectiveness of collaborative problem-solving in promoting students’ critical thinking and to determine, based on evidence, whether and to what extent collaborative problem solving can result in a rise or decrease in critical thinking. The findings show that (1) collaborative problem solving is an effective teaching approach to foster students’ critical thinking, with a significant overall effect size (ES = 0.82, z = 12.78, P < 0.01, 95% CI [0.69, 0.95]); (2) in respect to the dimensions of critical thinking, collaborative problem solving can significantly and successfully enhance students’ attitudinal tendencies (ES = 1.17, z = 7.62, P < 0.01, 95% CI[0.87, 1.47]); nevertheless, it falls short in terms of improving students’ cognitive skills, having only an upper-middle impact (ES = 0.70, z = 11.55, P < 0.01, 95% CI[0.58, 0.82]); and (3) the teaching type (chi2 = 7.20, P < 0.05), intervention duration (chi2 = 12.18, P < 0.01), subject area (chi2 = 13.36, P < 0.05), group size (chi2 = 8.77, P < 0.05), and learning scaffold (chi2 = 9.03, P < 0.01) all have an impact on critical thinking, and they can be viewed as important moderating factors that affect how critical thinking develops. On the basis of these results, recommendations are made for further study and instruction to better support students’ critical thinking in the context of collaborative problem-solving.

In this study, the influence of hydrothermal reaction temperatures on V2O5synthesized via a green facile mild hydrothermal method at six different reaction temperatures ranging from 100 to 200 °C, at steps of 20 °C and the physical properties the synthesized samples have been investigated. The x-ray diffraction pattern confirms the stable orthorhombic crystal structure of the synthesized samples at all reaction temperatures. The scanning electron microscopy and transmission electron microscopy images demonstrate the particle-like morphology, and these characterizations affirmed that the particles’ size became larger with the increase in the reaction temperatures. To study the functional groups, Fourier-transform infrared investigation has been employed. The bandgap of the synthesized samples has been estimated using UV-vis diffuse reflectance spectra and was found to vary from 2.08 to 2.15 eV, which implies their suitability for absorbing a significant amount of visible light. The photocatalysis of methylene blue with synthesized samples has been carried out to investigate the photocatalytic efficiency. Pure V2O5 synthesized at a lower reaction temperature (100 °C) possesses a lower bandgap and, accordingly, higher photocatalytic efficiency.
Comparing L2 translation, translation revision, and post-editing competences in translation trainees

Published: January 2023

AbstractTranslation proper is rarely the sole activity that translators undertake in today’s translation market. Translators regularly function as revisers or post-editors, requiring them to check human or machine translations to make or recommend changes to improve translation quality. Various construct and performance models of and studies into translation competence (TC), translation revision competence (TRC), and post-editing competence (PEC) exist. However, a fundamental question remains unanswered to date: how similar or different TC, TRC, and PEC are. Using indirect translations (L1 Dutch, L2 French), we collected and analyzed translation, translation revision (TR), and post-editing (PE) data from 11 graduate translation trainees. Our exploratory study shows that TRC and PEC appear to have different competences, with trainees performing better for TR than PE. However, TRC and PEC do appear to have a common core, which does not differ significantly across tasks: problem detection.
Self-consistent computation of spin torques and magneto-resistance in tunnel junctions and magnetic read-heads with metallic pinhole defects
Authors: Lepadatu Serban , Dobrynin Alexey 
Published: January 2023

Abstract
A three-dimensional self-consistent spin transport model is developed, which includes both tunnelling transport, leading to tunnelling magneto-resistance, as well as metallic transport, leading to giant magneto-resistance. An explicit solution to the drift-diffusion model is also derived, which allows analysing the effect of both the reference and free layer thickness on the spin-transfer torque polarization and field-like coefficient. It is shown the model developed here can be used to compute the signal-to-noise ratio in realistic magnetic read-heads, where spin torque-induced fluctuations and instabilities limit the maximum operating voltage. The effect of metallic pinhole defects in the insulator layer is also analysed. Increasing the area covered by pinholes results in a rapid degradation of the magneto-resistance, following an inverse dependence. Moreover, the spin torque angular dependence becomes skewed, similar to that obtained in fully metallic spin valves, and the spin-transfer torque polarization decreases. The same results are obtained when considering tunnel junctions with a single pinhole defect, but decreasing cross-sectional area, showing that even a single pinhole defect can significantly degrade the performance of tunnel junctions and magnetic read-heads below the 40 nm node.
Risk communication regarding radiation exposure by experts using two concepts of regulatory science and ALARA
Authors: Yoshida Yoshitoku 
Published: January 2023

Abstract
In the Tohoku region of Japan, risk communication programs on radiation exposure are of great importance, especially with respect to reducing the stress and anxiety among those affected by radiation exposure. Although the concepts of ‘as low as reasonably achievable’ (ALARA) and regulatory sciences (RS) were very important for the smooth operation of risk communication among a wide range of stakeholders, our previous research showed that only 23.5% and 16.5% of medical doctors in Japan had an accurate awareness of them, respectively. To make risk communication more effective, this study examined the levels of awareness of the concepts of ALARA and RS among academic experts in Japan and compared their level of awareness of technical terms regarding radiation to that of the expected level for a layperson. This study also showed that, even among faculty working at graduate schools in Japan, only 29.8% and 39.4% had an accurate knowledge of ALARA and RS. To improve the knowledge of laypeople and experts on these concepts, they should be added to the primary education curriculum. This study demonstrated that among experts in many academic fields, a significant range of estimates existed of lay knowledge of technical terms regarding radiation. The highest scores were assigned by faculty in the field of humanities. Thus, before conducting risk communications, experts from all fields should identify the expected level of awareness among laypeople on the topic. In addition, risk communications regarding radiation should be conducted by academic experts and healthcare professionals together with facilitators or lecturers.
Effects of macroparticle weighting in axisymmetric particle-in-cell Monte Carlo collision simulations
Authors: Hara Kentaro , Robertson Timothy , Kenney Jason , Rauf Shahid 
Published: January 2023

Abstract
In this paper, the effects of macroparticle (MP) weighting on the plasma discharge, particularly near the centerline, are investigated using a two-dimensional axisymmetric particle-in-cell Monte Carlo collision (PIC/MCC) model. A variable MP weight according to the radial position of the MPs is employed to maintain sufficient number of MPs near the centerline of the plasma source. The plasma density obtained from the PIC/MCC simulations for low-pressure (25–100 mTorr) capacitively coupled plasmas is found to be artificially large when the MP weight near the centerline is not well resolved, demonstrating the need for particle convergence studies for axisymmetric PIC/MCC simulations.
Thermodynamic irreversibility analysis of water conveying argentum and titania nanoparticles subject to inclined stretching surface
Authors: Sarfraz Mahnoor , Khan Masood 
Published: January 2023

Abstract
Hybrid nanofluids deliberately improve the characteristics of heat transmission and pressure drop in comparison to conventional nanofluids. The current study aims to inspect the energy transport and thermodynamic irreversibility effects of the buoyancy induced hybrid nanofluid flow. The mixture contains titania and argentum/silver nanoparticles over a vertically inclined stretching surface. The effects of heat generation and absorption, buoyancy and Lorentz force are added as well. The fact that nanoparticles have higher thermal and electrical conductivities means that this study can also be used for applications involving energy storage and catalytic supports. The problem is solved via bvp4c, a built-in technique in MATLAB. The similarity ansatzes are used to develop a system of ordinary differential equations. A comparison of current results with the existing ones in literature are also found to be in exact agreement. The asymptotic behavior for low and high magnetic number is determined. The nanoparticles concentration enhanced the flow field and temperature distribution; however, it reduced the entropy generation phenomenon and pressure field, causing pressure drop. The numerical and asymptotic values (for low magnetic number) of heat transfer rate and coefficients of skin frictions of free convective flow are declined due to increment in Prandtl number.

Moreover, we also investigate the structure scalars for dust ball. The dynamical effects on cluster of stars are examined via structure scalars in the presence of Gauss-Bonnet gravity. It is found that Gauss-Bonnet parameter representing exotic material in the cluster plays a vital role in governing the dynamics of cluster of stars.
Measurement-based interleaved randomised benchmarking using IBM processors
Authors: Strydom Conrad , Tame Mark 
Published: January 2023

Abstract
Quantum computers have the potential to outperform classical computers in a range of computational tasks, such as prime factorisation and unstructured searching. However, real-world quantum computers are subject to noise. Quantifying noise is of vital importance, since it is often the dominant factor preventing the successful realisation of advanced quantum computations. Here we propose and demonstrate an interleaved randomised benchmarking protocol for measurement-based quantum computers that can be used to estimate the fidelity of any single-qubit measurement-based gate. We tested the protocol on IBM superconducting quantum processors by estimating the fidelity of the Hadamard and T gates—a universal single-qubit gate set. Measurements were performed on entangled cluster states of up to 31 qubits. Our estimated gate fidelities show good agreement with those calculated from quantum process tomography. By artificially increasing noise, we were able to show that our protocol detects large noise variations in different implementations of a gate.
Bounding the photon mass with the dedispersed pulses of the Crab pulsar and FRB 180916B
Authors: Chang Chen-Ming , Wei Jun-Jie , Zhang Song-bo , Wu Xue-Feng 
Published: January 2023

Abstract
Tight limits on the photon mass have been set through analyzing the arrival time differences of photons with different
frequencies originating from the same astrophysical source. However, all these constraints have relied on using
the first-order Taylor expansion of the dispersion due to a nonzero photon mass. In this work, we present an analysis
of the nonzero photon mass dispersion with the second-order derivative of Taylor series. If the arrival time delay corrected
for all known effects (including the first-order delay time due to the plasma and photon mass effects) is assumed to be
dominated by the second-order term of the nonzero photon mass dispersion, a conservative upper limit on the photon mass can be estimated. Here we show that the dedispersed pulses with the second-order time delays from the Crab pulsar and
the fast radio burst FRB 180916B pose strict limits on the photon mass, i.e.,
mγ,2
≤ 5.7 × 10-46 kg ≃ 3.2 × 10-10 eV/c
2
and mγ,2
≤ 6.0 × 10-47 kg ≃ 3.4 × 10-11 eV/c
2, respectively.
This is the first time to study the possible second-order photon mass effect.
Limit-cycle-oscillation induced from the positive feedback amplification of radial electric field in the scrape-off-layer
Authors: Kim J.Y. , Han H.S. , Jung L. 
Published: January 2023

Abstract
Based on a heuristic model of the scrape-off-layer (SOL) plasma dynamics, a new type of limit-cycle-oscillation (LCO) is shown to be possible in the SOL region. The key trigger process is the positive feedback amplification of the SOL radial electric field through the SOL turbulence suppression and temperature profile steepening. This SOL-LCO can make the edge plasma inside the separatrix also have an oscillation motion, taking the features qualitatively similar to those observed in the recent ASDEX Upgrade experiment (Cavedon et al 2017 Nucl. Fusion
57 014002). With the above positive feedback process much more feasible when the ion magnetic curvature drift direction is toward the X-point, the present model also provides an explanation of why the LCO is mostly observed in such a favorable magnetic configuration.

Authors: Leite Mimmi , Nordby Karl-Christian , Skare Øivind , Ulvestad Bente , Ellingsen Dag Gunnar , Dahl Kari , Johansen Thea , Petter Skaugset Nils 
Published: January 2023

Abstract

Objectives
This study aimed to assess the exposure to a selection of aerosols and gases in the work environment for workers performing tunnel construction using tunnel boring machines (TBMs), to identify determinants of exposure based on the information available and to calculate robust estimates of exposure using a statistical model. The focus was particulate matter (PM) and respirable crystalline silica (RCS). In addition, concentrations of nitrogen dioxide (NO2), elemental carbon (EC), and oil mist were assessed.

Methods
Personal sampling was conducted from February 2017 to February 2019. PM in the thoracic and the respirable aerosol fractions was collected, and RCS was determined in the respirable aerosol fraction. Context information was collected on questionnaires. Because the workers could participate in the sampling more than once and multiple measurements were performed on the same date a mixed model was used in the analysis. Concentrations of PM and RCS are presented as estimated and measured geometric means (GMest and GMmea) and estimated arithmetic mean (AMest) in addition to the median. Measured concentrations of NO2, EC, and oil mist are presented as geometric means.

Results
A total of 290 and 289 personal samples of PM in the thoracic and respirable aerosol fractions were available for analysis, respectively. Work title/work location, type of work (production, maintenance, or a combination of the two), and date of sampling were identified as determinants of exposure. Workers in the front of the TBMs had the highest exposure to PM and RCS. The GMest of RCS exposure varied from 35 to 413 μg m–3 depending on the work title. The geometric standard deviations for measured RCS concentrations by work title ranged from 1.6 to 3.5. A total of 16 samples of NO2 and EC and 12 samples of oil mist were collected. Maximum values of NO2 and EC were 54 µg m–3 and 23 µg m–3, respectively. The maximum measured value of oil mist was 0.08 mg m–3.

Conclusions
All TBM workers were exposed to PM and RCS. Exposure to RCS may be substantial, and workers in front of the TBM were exposed to the highest concentrations of both PM and RCS. A day-to-day variation was found, probably caused by differences in drilling activities. Preventive measures are warranted to keep the exposure to PM and consequently the exposure to RCS as low as possible to protect the health of workers in tunnel construction.

Authors: Thawanyarat Kometh , Hinson Chandler , Gomez Diego A , Rowley Mallory , Navarro Yelissa , Johnson Chandler , Venditto Chelsea M 
Published: January 2023

Abstract

Background
Instagram (Menlo Park, CA) has become a popular means of advertisement for aesthetic surgery procedures, influencing patients’ likelihood of undergoing a procedure. In this study, the authors aim to explore public interest in aesthetic procedures before and after the Instagram platform started gaining in popularity through Google Trends (Google, Mountain View, CA), a platform with previously demonstrated utility for tracking interest in surgical procedures.

Objectives
The authors hypothesize that as a result of increased medical marketing on Instagram, there is an increase in public interest in elective procedures of plastic surgery.

Methods
Trends in the United States for given search terms and volumes were gathered through Google Trends between April 2004 and January 2022. Search terms included popular aesthetic procedures based on the 2020 Aesthetic Plastic Surgery National Data Bank Statistics. The search volumes were normalized, and a bivariate regression analysis of panel data was then applied to the aggregate trendlines to determine whether a statistically significant change in search volume occurred following the increase in user traffic of the Instagram platform.

Results
The authors found significant variations in search volume for plastic surgery procedures before and after April 2012. Blepharoplasty, Botox, brachioplasty, breast implant removal, breast reduction, brow lift, butt lift, hair transplantation, lip augmentation, male breast surgery, mastopexy, mentoplasty, otoplasty, platysmaplasty, rhinoplasty, and thighplasty (P &lt; .000) had statistically significant increases in search volume, whereas buccal fat removal (P = .003) had a statistically significant decrease in search volume after April 2012.

Conclusions
The authors observed a significant increase in public interest in both surgical and nonsurgical aesthetic procedures after Instagram gained popularity in the April of 2012.

Published: January 2023

Abstract

Background
Limited data are available to guide effective antibiotic durations for hospitalized patients with complicated urinary tract infections (cUTIs).

Methods
We conducted an observational study of patients ≥18 years at 24 US hospitals to identify the optimal treatment duration for patients with cUTI. To increase the likelihood patients experienced true infection, eligibility was limited to those with associated bacteremia. Propensity scores were generated for an inverse probability of treatment weighted analysis. The primary outcome was recurrent infection with the same species ≤30 days of completing therapy.

Results
1099 patients met eligibility criteria and received 7 (n = 265), 10 (n = 382), or 14 (n = 452) days of therapy. There was no difference in the odds of recurrent infection for patients receiving 10 days and those receiving 14 days of therapy (aOR: .99; 95% CI: .52–1.87). Increased odds of recurrence was observed in patients receiving 7 days versus 14 days of treatment (aOR: 2.54; 95% CI: 1.40–4.60). When limiting the 7-day versus 14-day analysis to the 627 patients who remained on intravenous beta-lactam therapy or were transitioned to highly bioavailable oral agents, differences in outcomes no longer persisted (aOR: .76; 95% CI: .38–1.52). Of 76 patients with recurrent infections, 2 (11%), 2 (10%), and 10 (36%) in the 7-, 10-, and 14-day groups, respectively, had drug-resistant infections (P = .10).

Conclusions
Seven days of antibiotics appears effective for hospitalized patients with cUTI when antibiotics with comparable intravenous and oral bioavailability are administered; 10 days may be needed for all other patients.
