Enhancing Perceptions of Mathematics Assignments by Increasing Relative Problem Completion Rates through the Interspersal Technique.

Abstract Students solved mathematics problems from 4 assignment pairs. Each control assignment contained 18 target multiplication problems that were 4 × 1-digit (4 × 1), 4 × 2, 4 × 3, or 4 × 4. Each paired experimental assignment contained 18 similar problems plus 6 interspersed 1 × 1-digit problems. After computing problems from each pair of assignments, the students rated them and chose 1 for homework. Across all assignment pairs, problem completion rates were greater on the experimental assignments, and significantly more students chose a new experimental, rather than control, assignment for homework. Furthermore, as the discrepancy between problem completion rates increased across assignment pairs, the probability of students' choosing the experimental assignment for homework and rating the experimental assignment more favorably with respect to difficulty, effort, and time also increased. The relationship between student choice behaviors and relative problem completion rates has theoretical and applie.
Comparison of the AC losses of BSCCO and YBCO conductors by means of numerical analysis

This paper presents a quantitative comparison of the AC loss performance of two BSCCO and two YBCO conductors, characterized by the same self-field critical current of 150 A. We compare a 37-filamentary BSCCO tape, a 16-filamentary BSCCO square wire, a standard YBCO tape, and a stack of four narrower YBCO tapes. The comparison is made using a numerical technique, based on the finite-element method, which employs a non-linear E–J relation and a dependence of the local critical current density Jc on the local magnetic field. For the simulation of YBCO conductors, a new ‘shell-region’ model is utilized. This overcomes the geometry and mesh problems typical of superconductors with very high geometric aspect ratio. Different AC working conditions are simulated: self-field, applied external field, and combined transport current and external field of varying orientation. We outline the advantages of using BSCCO or YBCO conductors for the different applications. Various magnetic field and current density profiles are investigated in order to illustrate the reasons for the loss difference in the four conductors. Particular attention is drawn to the YBCO tape and the YBCO stack, whose AC loss characteristics are less well known than those of BSCCO conductors.
Motivating nurses' coworker‐directed helping behaviour during the COVID‐19 pandemic: Role of managerial humour and nurses' power distance orientation

Abstract Aims The aims of the research are to investigate (1) the influence of managerial humour on nurses' coworker‐directed helping behaviour, (2) the mediating effect of nurses' feelings of energy between managerial humour and nurses' coworker‐directed helping behaviour and (3) the moderating effect of nurses' power distance orientation. Design This is a quantitative study. A three‐wave survey design was conducted to collect data from direct managers to nurse dyads. Methods The random sampling method was employed. Data were collected from the supervisor to subordinate dyad at three time points during the first half of 2021. A total of 235 paired data sets of nurses and their direct managers were collected from a large state‐owned Chinese hospital. We used hierarchical regression analyses via SPSS 22.0 software to examine the hypotheses. Results (1) Managerial humour can foster nurses' coworker‐directed helping behaviour via accumulating their feelings of energy. (2) Power distance orientation moderates the effect of managerial humour on feelings of energy as well as the indirect effect of managerial humour on nurses' coworker‐directed helping behaviour via feelings of energy, in a way that these effects are stronger when nurses have higher (vs. lower) level of power distance orientation. Conclusion Managerial humour can increase nurses' feelings of energy, which in turn, motivates them to help their coworkers. Nurses' power distance orientation is an important boundary condition that constrains managerial humour effectiveness. Impact Hospital managers could use more humour during their interactions with nurses because managerial humour can promote nurses' feelings of energy and coworker‐directed helping behaviour. Hospitals can take humour into account during managers' selection and training to improve management effectiveness. Managers in eastern countries should use more humour during their interactions with followers. Patient or public contribution Nurses and their direct managers from a large state‐owned Chinese hospital contributed to this study by completing the survey.
A fluid treatment of the plasma presheath for collisionless and collisional plasmas

The presheath region of an unmagnetized plasma is treated using ion fluid equations in the collisional and collisionless regimes. Effects of neutral gas–plasma interactions are included through source terms in the fluid equations. Ion–ion collisional effects are included through the closure conditions of the fluid equations. In the collisionless regime, the perpendicular ion temperature is assumed constant and independent of the parallel ion temperature. In the collisional limit, the parallel and perpendicular temperatures are assumed equal throughout the presheath. Profiles of ion density, flow velocity, parallel temperature, and energy flux obtained by integrating the fluid equations compare well to previously published kinetic results in the collisionless case. Ion–ion Coulomb collisions are shown to have a negligible effect on the ion particle and energy flux into the sheath.
Aptamers for Addressed Boron Delivery in BNCT: Effect of Boron Cluster Attachment Site on Functional Activity

Among the great variety of anti-cancer therapeutic strategies, boron neutron capture therapy (BNCT) represents a unique approach that doubles the targeting accuracy due to the precise positioning of a neutron beam and the addressed delivery of boron compounds. We have recently demonstrated the principal possibility of using a cell-specific 2′-F-RNA aptamer for the targeted delivery of boron clusters for BNCT. In the present study, we evaluated the amount of boron-loaded aptamer inside the cell via two independent methods: quantitative real-time polymerase chain reaction and inductive coupled plasma–atomic emission spectrometry. Both assays showed that the internalized boron level inside the cell exceeds 1 × 109 atoms/cell. We have synthesized closo-dodecaborate conjugates of 2′-F-RNA aptamers GL44 and Waz, with boron clusters attached either at the 3′- or at the 5′-end. The influence of cluster localization was evaluated in BNCT experiments on U-87 MG human glioblastoma cells and normal fibroblasts and subsequent analyses of cell viability via real-time cell monitoring and clonogenic assay. Both conjugates of GL44 aptamer provided a specific decrease in cell viability, while only the 3′-conjugate of the Waz aptamer showed the same effect. Thus, an individual adjustment of boron cluster localization is required for each aptamer. The efficacy of boron-loaded 2′-F-RNA conjugates was comparable to that of 10B-boronophenylalanine, so this type of boron delivery agent has good potential for BNCT due to such benefits as precise targeting, low toxicity and the possibility to use boron clusters made of natural, unenriched boron.
Occlusal Plane Modification in Clear Aligners Treatment: Three Dimensional Retrospective Longitudinal Study

The purpose of the present study was to evaluate: (i) maxillary occlusal plane changes after clear aligners therapy with a 3D measurement technique; and (ii) as a secondary outcome, if such changes were correlated to the patient’s 1axilla-mandibular divergence. 3D maxillary models of 32 patients (7 males and 25 females; mean age 22.3 +/− 3.4 year) treated with clear aligners were analyzed. The angle (α) between a reference palatine plane and a maxillary occlusal plane was measured. Five angular cephalometric measurements (NSL/MP; PP-OP; OP-MP; PP-MP; PFH/AFH%) were performed and related to Δα. The subjects were further divided into three groups according to facial divergence. After aligner treatment, Δα increased in hyperdivergent patients and decreased in hypodivergent patients (p < 0.05). Δα showed a significant positive correlation with NSL/MP (rho = 0.44) and negative correlation with PFH/AFH% (rho = −0.53). Aligners treatment produced a counterlockwise rotation of the maxillary occlusal plane, even if this rotation occurs differently depending on divergence.
FACTORS THAT EFFECT TURNOVER INTENTION WITH JOB SATISFACTION AS AN INTERVENING VARIABLE AT FOOD AND BEVERAGES DISTRIBUTION COMPANIES IN BATAM

Nowadays workplace filled with Gen X and Y employee, it is stated that by 2025, the employment field will be filled by millennials. Human resources are an asset to a company, turnover intention emerge a big problem for company every year. This research will be aim to determine and analyze factors that affect turnover intention with job satisfaction as intervening variable. Questionnaires was distributed to 360 employee that work in food and beverages distribution companies in Batam. However, there is only 280 data that can be analyze due to incompleteness and some questionnaire that didn’t return. The data is examined with SPSS to analyze the descriptive data and Smart PLS program to examine the relationship between independent to dependent variables while intervening through an intervening variable. The result of this study shown that there is a direct effect from salary, transformational leadership and job satisfaction toward turnover intentions. It also shows that there is an indirect effect from salary and transformational leadership towards turnover intention while it is mediating through job satisfaction. In other hand, it was found that work stress, emotional intelligence is not significant in giving effect towards turnover intention with or without the intervening from job satisfaction.
Quality Improvement Attitudes among Saudi Nurses in Hospitals in Qassim, Saudi Arabia: A Cross-Sectional Survey

Background: This study aimed to provide an overview of perceptions of quality improvement among nurses working in Saudi Arabia. Methods: We conducted a descriptive cross-sectional study of 497 Saudi nurses working in public and private hospitals in Al-Qassim Province. Descriptive statistics were computed for quality improvement nursing attitude items and demographic factors. Results: A total of 497 nurses took part in the study; 29.1% of participants were females, and half of the participants were between the ages of 25–30 years. Most respondents were employed in governmental hospitals (98.7%), and 41.9% of participants had work experience ranging between 1 and 5 years. Nurses involved in providing direct patient care recognize the quality improvement attitudes related to changes in the healthcare delivery processes. Saudi nurses’ quality improvement nursing attitudes were moderate. Female, married, and older age group nurses and nurses who were working fewer hours per week showed better quality improvement attitudes. Conclusions: Saudi nurses’ quality improvement nursing attitudes are found to be moderate. Age, gender, marital status, and working hours of nurses are associated with their quality improvement attitudes. To empower nurses to improve healthcare, nursing administrators need to focus on improving the quality improvement attitudes environment.
Towards Understanding Teacher Mentoring, Learner WCF Beliefs, and Learner Revision Practices Through Peer Review Feedback: A Sociocultural Perspective

Background. The existing literature has focused on learner perceptions or beliefs about peer review tasks over the recent decade. However, little has been known about the relationships among learner beliefs about written corrective feedback (WCF), related teacher mentoring process, and learner revision practices. Purpose. We thus aimed at addressing the gap by exploring how teacher mentoring and learner WCF beliefs may inform learner revision practices in the peer-reviewed process. Methods. In this mixed-method study, we included four Chinese EFL students majoring in English as the participants and collected their WCF belief survey data. We also collected their actual practice data through PeerCeptiv, an online writing and rewriting platform. In addition, we traced the teacher mentoring practices and interviewed the participants about their beliefs and practices in the peer review and back-evaluation process. Results. Through the mixed-methods design, we reported our major findings: the student participants believed empathy and resonance was the primary advantage of peer feedback, and teacher mentoring facilitated them in understanding and performing the peer review and revision tasks; we also found the student review process consisted of evaluating, resonating, learning, and reflecting practices and the student revision process included crediting, arguing, correcting, and polishing practices. Implications. From a sociocultural perspective, we centered our discussion on these research findings by claiming that scaffolding in different forms work together enhance learner performance and student beliefs appear in a complex manner with student actual revision practices. We also offered insights for future studies and practical implications for language teachers.
Highly Pathogenic Avian Influenza A(H5N1) Virus Clade 2.3.4.4b in Wild Birds and Live Bird Markets, Egypt

Clade 2.3. 4.4 H5Nx influenza viruses have further diversified into several subclades. Sub-clade 2.3. 4.4b H5N1 viruses have been widely circulating in wild birds and detected in Europe, Africa, Asia, and North America since October 2020. In this study, we report the first detection of highly pathogenic avian influenza H5N1 clade 2.3. 4.4b viruses in wild birds and domestic ducks from live bird markets in Egypt. Phylogenetic analysis revealed that the Egyptian H5N1 virus retained the genomic composition of Eurasian strains. Mutations in the viral proteins associated with zoonotic potential and pathogenicity were detected in Egyptian isolates. Egypt is considered a hot spot for the evolution of the influenza virus, so active surveillance of avian influenza viruses in Egypt is warranted.
Diagnosis of Track Forecast Errors for Tropical Cyclone Rita (2005) Using GEFS Reforecasts

AbstractAnalysis and diagnosis of the track forecasts for Tropical Cyclone (TC) Rita (2005) from the Global Ensemble Forecast System (GEFS) reforecast dataset is presented. The operational numerical weather prediction guidance and GEFS reforecasts initialized at 0000 UTC 20–22 September 2005, 2–4 days prior to landfall, were all characterized by a persistent left-of-track error. The numerical guidance indicated a significant threat of landfall for the Houston, Texas, region on 24 September. The largest mass evacuation in U.S. history was ordered, with the evacuation resulting in more fatalities than TC Rita itself. TC Rita made landfall along the Texas–Louisiana coastal zone on 24 September. This study utilizes forecasts from the GEFS reforecast and a high-resolution regional reforecast. The regional reforecast was generated using the Advanced Hurricane Weather Research and Forecasting Model (AHW) with the GEFS reforecasts providing the initial and boundary conditions. The results show that TC Rita’s trac.
Permanence results for dimension-theoretic coarse notions

Coarse topology is the study of interesting topological properties of discrete spaces. In this dissertation, we will discuss a coarse analog of dimension and several generalizations. We begin by extending the class of metric spaces for which these properties are known. The next few chapters are devoted to generalizing these properties to all coarse spaces and exploring the relationships between these generalizations. Finally, we give a brief discussion of computational topology, highlighting how to generate the Rips and Cech simplicial complexes from a set of data. We end with some code written to generate these complexes, and present some thoughts on how to use this to compute certain coarse properties.
Histopathological Studies on the Effect of Taurine Against Etoposide-Induced Acute Liver and Kidney Toxicity in Female Albino Rats

Etoposide (ETP) is a topoisomerase Ⅱ (TOP Ⅱ) inhibitor and one of the leading chemotherapeutic drugs for treating a wide variety of tumors. However, ETP induced hepatotoxicity and nephrotoxicity limits its clinical use. This study aims to investigate the protective potential of taurine (Tau) to mitigated histopathological changes in the liver and kidneys of female albino rats treated with ETP. A total of 18 female rats were divided into three groups; control group, ETP-exposed group received intraperitoneal injection of ETP on the first 3 days of the study for a total cumulative dose of 44 mg/kg to induce hepatotoxicity and nephrotoxicity, ETP + Tau group received ETP as stated previously with 400 mg/kg/day of Tau via oral gavage for 15 days. Sections from the liver and kidney were evaluated under light microscope and ETP-exposed group revealed vascular congestion, chronic inflammatory cell infiltration predominantly lymphocytes, edema, vacuolar degeneration, atypical cells, pyknosis, and necrosis while liver and kidney sections of rats treated with combination of ETP + Tau group exhibited marked alleviation of the histopathological damage. The study concludes that treatment with ETP induced marked structural damages in the liver and kidney and such morphological damages are effectively diminished by administering Tau.
The Effect of Tissue Stromal Vascular Fraction as Compared to Cellular Stromal Vascular Fraction to Treat Anal Sphincter Incontinence

Background: The long-term prognosis of current treatments for anal sphincter incontinence (ASI) is poor. Here, we explored the efficacy of tissue adipose stromal vascular fraction SVF (tSVF) on ASI and compared it to that of cellular SVF (cSVF). We then investigated possible mechanisms. Methods: Rat cSVF and tSVF were isolated and labeled with DIL. One day after modeling, three groups received phosphate-buffered saline (PBS), cSVF, tSVF, respectively. The control group received nil modeling nor any treatments. The effect was assessed by function test for anal pressure and electromyography, and staining for fiber content, proliferation and differentiation at day 5 and day 10. Results: cSVF injection resulted in faster healing than tSVF. The cSVF group showed significant improvement on anal pressure on day 10. For the electromyography test, cSVF showed significant improvement for the frequencies on day 10, and for the peak values on both time points, while tSVF showed significant improvement for the peak values on day 10. The two SVF both alleviated fibrosis. Immunofluorescence tracing identified differentiation of some injected cells towards myosatellite cells and smooth muscle cells in both SVF groups. For all the tests, the tSVF group tends to have similar or lower effects than the cSVF group with no significant difference. Conclusion: cSVF and tSVF are both safe and effective in treating ASI, while the effect of cSVF is slighter higher than tSVF.
Superconducting Correlation of Two-Dimensional Hubbard Model near Half-Filling

Superconducting correlation of the Hubbard model on a square lattice is reinvestigated by quantum Monte Carlo method. Results from more than one order of magnitude larger Monte Carlo steps than before are presented to discuss the convergence of the data to the ground state. By examining the dependence on the choice of initial trial states as well as on the Trotter number in detail, the superconducting correlation in the ground state is reliably obtained up to 12×12 lattice away from the half-filling and up to 16×16 lattice at the half-filling, which substantially improve former results near the half-filling. Various channels of pairing in the ground state show no system size dependence and remain quite short ranged at any filling including the region close to the half-filling. Numerical data show further evidence that neither extended s - nor d -wave superconducting state is possible in the two-dimensional Hubbard model.
The electromagnetic radiation from a finite antenna

Textbooks rarely give time−domain solutions to antenna problems. For the case of a finite linear antenna along which a fixed current waveform propagates, we present analytical time−domain solutions for the electric and magnetic radiation (far) fields. We also give computer solutions for the total (near and far) fields. The current waveform used as an example in the computer calculations approximates that of a lightning return−stroke, a common geophysical example of the type of radiation source under consideration.
Evolution of a wave packet into vortex loops in a laminar separation bubble

A laminar boundary layer develops in a favourable pressure gradient where the velocity profiles asymptote to the Falkner & Skan similarity solution. Flying-hot-wire measurements show that the layer separates just downstream of a subsequent region of adverse pressure gradient, leading to the formation of a thin separation bubble. In an effort to gain insight into the nature of the instability mechanisms, a small-magnitude impulsive disturbance is introduced through a hole in the test surface at the pressure minimum. The facility and all operating procedures are totally automated and phase-averaged data are acquired on unprecedently large and spatially dense measurement grids. The evolution of the disturbance is tracked all the way into the reattachment region and beyond into the fully turbulent boundary layer. The spatial resolution of the data provides a level of detail that is usually associated with computations. Initially, a wave packet develops which maintains the same bounded shape and form, while the amplitude decays exponentially with streamwise distance. Following separation, the rate of decay diminishes and a point of minimum amplitude is reached, where the wave packet begins to exhibit dispersive characteristics. The amplitude then grows exponentially and there is an increase in the number of waves within the packet. The region leading up to and including the reattachment has been measured with a cross-wire probe and contours of spanwise vorticity in the centreline plane clearly show that the wave packet is associated with the cat's eye pattern that is a characteristic of Kelvin–Helmholtz instability. Further streamwise development leads to the formation of roll-ups and contour surfaces of vorticity magnitude show that they are three-dimensional. Beyond this point, the behaviour is nonlinear and the roll-ups evolve into a group of large-scale vortex loops in the vicinity of the reattachment. Closely spaced cross-wire measurements are continued in the downstream turbulent boundary layer and Taylor's hypothesis is applied to data on spanwise planes to generate three-dimensional velocity fields. The derived vorticity magnitude distribution demonstrates that the second vortex loop, which emerges in the reattachment region, retains its identity in the turbulent boundary layer and it persists until the end of the test section.
