Transition in learning during COVID‐19: Student nurse anxiety, stress, and resource support

Abstract The purpose of this study was to explore anxiety and stress experienced by first‐semester nursing students and identify sources of support during a transition from a face‐to‐face to an online learning platform during the first months of the COVID‐19 pandemic. This descriptive study used a web‐based survey distributed to nursing students 2 months after the completion of their first semester. The survey questions were adapted from the Anxiety Symptoms Checklist and the College Student Stress Scale. The survey link was emailed to 79 students, with 56 consenting, and 50 completing the survey. The most commonly reported symptoms were difficulty concentrating (90%) and feeling anxious or overwhelmed (84%). Most respondents reported anxiety related to the pandemic, with 84% being concerned about a friend or relative contracting COVID‐19, and with 70% fearful of becoming infected themselves. The majority of respondents expressed concerns related to difficulty handling academic workload (62%), and the need to perform well in school (56%). To decrease anxiety and stress, the faculty should foster a structured learning environment; abide by the course schedule; communicate changes or updates in a timely fashion; adapt assignments to fit the learning environment; utilize campus, local, state, and national resources; practice self‐care; and extend grace.
DFT Calculation of NMR JFF Spin−Spin Coupling Constants in Fluorinated Pyridines

All four isotropic contributions to the NMR fluorine−fluorine coupling constants (Fermi contact, FC, spin-dipolar, SD, paramagnetic spin−orbit, PSO, and diamagnetic spin−orbit, DSO) have been calculated for 2,6-difluoropyridine, 2,4,6-trifluoropyridine, perfluoropyridine, and 2-Br-3,4,5,6,7,8-hexafluoroquinoline by means of density functional theory in combination with the rather modest 6-311G** basis set. Experimental values ranging from −20.3 to +45.8 Hz are semiquantitatively reproduced for three- to seven-bond couplings, suggesting that the different electronic effects responsible for the spin−spin interactions are adequately taken into account. In all cases, the relative importance of noncontact terms was examined. With few exceptions, the sum of the SD and PSO noncontact terms is larger than the FC contact contribution, even though in most cases the two noncontact values have opposite signs. The widespread assumption that the Fermi contact term dominates scalar spin−spin couplings in the case of lig.

Developing a new individual earthquake resilience questionnaire: A reliability and validity test

Earthquakes pose serious threats to the world. Good individual resilience can cope with disaster well, but there were few appropriate assessment tools. The purpose of this study was to develop a new individual earthquake resilience questionnaire and test its reliability and validity. First, we built the framework of the individual earthquake resilience questionnaire based on expert interviews. Then, we established the initial version of questionnaire and used the Delphi method and item selection to modify it by qualitative and quantitative methods. Finally, we built the final version of questionnaire (contained 4 dimensions and 17 items) and tested the reliability and validity. The Cronbach’s α values of the four dimensions were between 0.79 and 0.91, the split-half reliabilities were between 0.85 and 0.93, and the test-retest reliabilities were between 0.72 and 0.80. The item content validity indexes were between 0.87–1, and the average questionnaire content validity index was 0.94. The correlation coefficients between each item and dimension with the total questionnaire ranged from 0.79–0.90 and 0.66–0.79, respectively. We used exploratory factor analysis to identify four common factors with a cumulative variance contribution rate of 74.97%. The questionnaire is a valid and reliable tool to measure individual resilience in the context of earthquake disasters.
Isomorphic decisional biases across perceptual tasks

Humans adjust their behavioral strategies to maximize rewards. However, in the laboratory, human decisional biases exist and persist in two alternative tasks, even when this behavior leads to a loss in utilities. Such biases constitute the tendency to choose one action over others and emerge from a combination of external and internal factors that are specific for each individual. Here, we explored the idea that internally-mediated decisional biases should stably occur and, hence, be reflected across multiple behavioral tasks. Our experimental results confirm this notion and illustrate how participants exhibited similar choice biases across days and tasks. Moreover, we show how side-choice behavior in a two alternative choice task served to identify participants, suggesting that individual traits could underlie these choice biases. The tasks and analytic tools developed for this study should become instrumental in exploring the interaction between internal and external factors that contribute to decisional biases. They could also serve to detect psychopathologies that involve aberrant levels of choice variability.
Three Channels for Gray Level Co-occurrence Matrix (GLCM) to detect Acute Lymphoblastic Leukemia (ALL) Images

Leukemia is one of the dangerous diseases causing the death of people. Based on our literature review, numerous methods have been utilized for leukemia detection with various performances. Therefore, this research aims to employ the three channels for GLCM to detect ALL based on the Lymphoblastic Leukemia Image Database (ALL-IDB2) dataset. This research has some novelties. Firstly, the proposed method related to segmentation has separated the main object and background and removed the noises. Secondly, Feature extraction of the proposed method has depicted the object in three-dimensional form, so that the object can be visualized in more details than one-dimensional. Therefore, this research contributes by proposing a novel method of GLCM to detect ALL. We have employed 260 images of ALL-IDB2 and conducted twenty experiments for each scenario. Our proposed method has proven that three channels of GLCM and testing sets using Manhattan and Euclidean Distance achieved 91.54% of maximum accuracy. It has better accuracy than a combination of the GLCMshape-based feature-SVM classifier method. Furthermore, we have demonstrated that the quantity of training sets has given an impact on accuracy performance. Our experiments show higher numbers of the training sets obtained higher accuracy. Besides accuracy, we also calculated the false-negative and false-positive. The average of the false-negative results contributes to stability. It means that the difference of the results among scenarios is insignificant and almost similar. Meanwhile, false-negative tends to decrease in percentage. This is inversely proportional to the increase in the amount of the training set used. Additionally, the use of large amounts of training sets can reduce misclassification for the false-negative rate. Additionally, we have measured the classification results using the Euclidean method, as shown in Figures 9, 10, and 11. In Figure 11, we have found several accuracies from the different number of training sets. Similar to the Manhattan method results have been obtained from 240 experimental of twelve scenarios. The accuracy results have a trend to move up in proportion to the number of training sets. It demonstrated that the number of training sets employed had influenced the accuracy results. Our proposed method obtained the maximum accuracy equal to the maximum accuracy of the Manhattan method, which is 91.54%, as demonstrated in Figure 9. Moreover, we have obtained 86.2% as the maximum of the average accuracy. The result shows that the maximum of the accuracy has produced higher than the Manhattan method. Meanwhile, false-negative tends to decrease in percentage. This is inversely proportional to the increase in the amount of the training set used. Based the Figure 11, we can conclude that the use of large amounts of training sets can reduce misclassification for false-negative rate.
In situ TEM observation of phase transformation in bulk metallic glass composites

Transformation-induced plasticity is a fundamental solution for improving the ductility of bulk metallic glass composites (BMGCs). However, the underlying mechanism remains controversial. Here, by using in situ transmission electron microscopy, we present direct observation of the transformation dynamics from β/ω phase to α’ phase of the crystalline dendrites in a TiZrCuBe BMGC under uniaxial tensile deformation. The transformation redistributes the stress in the adjacent matrix, making interfacial regions potential preferential sites for shear band nucleation. The high density of nucleation sites is believed to promote the formation of shear band networks and enhance the ductility of BMGCs. GRAPHICAL ABSTRACT
The electrochemical behaviour of Ti‐13Nb‐13Zr alloy in various solutions

The electrochemical behaviour of a near‐β Ti‐13Nb‐13Zr alloy for the application as implants was investigated in various solutions. The electrolytes used were 0.9 wt% NaCl solution, Hanks' solution and a culture medium known as minimum essential medium (MEM) composed of salts, vitamins and amino acids, all at 37 °C. The electrochemical behaviour was investigated by the following electrochemical techniques: open circuit potential measurements as a function of time, electrochemical impedance spectroscopy (EIS) and determination of polarisation curves. The obtained results showed that the Ti alloy was passive in all electrolytes. The EIS results were analysed using an equivalent electrical circuit representing a duplex structure oxide layer, composed of an inner barrier layer, mainly responsible for the alloy corrosion resistance, and an outer and porous layer that has been associated to osteointegration ability. The properties of both layers were dependent on the electrolyte used. The results suggested that the thickest porous layer is formed in the MEM solution whereas the impedance of the barrier layer formed in this solution was the lowest among the electrolytes used. The polarisation curves showed a current increase at potentials around 1300 mV versus saturated calomel electrode (SCE), and this increase was also dependent on the electrolyte used. The highest increase in current density was also associated to the MEM solution suggesting that this is the most aggressive electrolyte to the Ti alloy among the three tested solutions.

Crystal structure of monosamarium trithioborate, Sm[BS3]

BS3Sm, orthorhombic, Pna21 (no. 33), a = 7.3657(5) A, b = 6.0272(2) A, c = 8.8004(6) A, V = 390.69 A 3 , Z =4 , R(F 2 ) = 0.068, R(P) = 0.013, T = 295 K. Source of material Sm[BS3] was prepared by using a high-temperature highpressure route. Molar ratios o f1:3:6 ofsamarium (powder, ChemPur, 99.9 %), amorphous boron (ABCR, 99 %) and sulfur (Alfa Aesar, 99.9995 %, sublimed under vacuum to reduce contamination by oxygen below 1 %) were used. Molar ratios corresponding to the chemical composition of the title compound did not yield sufficiently pure materials. The educts were ground and filled into the assembly of the octahedral high pressure setup, under argon atmosphere of a glove box. Hexagonal boron nitride was used as the crucible material. High pressure conditions were achievedbyusingahydraulicuniaxialpress[1]. Forceredistribution was accomplished by a Walker-type module and MgO octahedra with an edge length of 18 mm [2]. Elevated temperatures were realized by resistive heating of graphite tubes enclosing the sample crucible. For the synthesis of Sm[BS3], the assembly was heated to 1673 K and compressed to 3 GPa for 5 h. Afterthepressureandheatingcycle,thearrangementwasinstantaneously removed and transferred into a glove box where the sample was isolated from the crucible. No indications of a reactionbetweenthesampleandthecruciblematerialwereobserved. The air- and humidity-sensitive compound Sm[BS3] was obtained as a red-brown polycrystalline material. Experimental details X-ray powder diffraction data were collected on a STOE StadiPMPdiffractometerinDebye-Scherrergeometry.TheGSASsoftware package [3] was used for the Rietveld refinements. The unit cellparametersatroomtemperatureweredeterminedfromX-ray powder diffraction data (CuK1), using LaB6(a= 4.15692(1) A) as internal standard, and refined by least squares refinements usingtheWinCSDprogram[4]. Thepositionoftheboronatomwas restrainedtobenearthecentreofgravityofthesulfuratomsofthe [BS3] 3– unit. The isotropic displacement parameters of the sulfur atoms were constrained to be equal and the corresponding parameter of the boron site was constrained to be equal to that of the attached sulfur atoms. Discussion The new RE thioborate Sm[BS3], obtained as a product of the high-pressure high-temperature experiments, is an isotype of the RE[BS3] series (RE= Ce, Pr, Nd) [5,6]. The crystal structure was refinedfromX-raypowderdiffractiondatausingtheRietveldrefinement method [7]. The crystal structure of Sm[BS3] is characterized by corrugated kagome nets formed by sulfur atoms, with the boron atoms occupying every second triangle, while Sm cations center the large hexagons. The corrugated nets are stacked along [100] according to the sequence ABAB. The coordination sphereofSmisformedbyninesulfurspeciesoriginatingfromsix neighboring thioborate units. Three of the [BS3] 3– units act as bidentate ligands, while the other three are in monodentate func
An immersive virtual reality game to train spatial attention orientation after stroke: A feasibility

Immersive virtual reality (IVR) may boost neglect recovery, as it can provide an engaging experience in a 3D environment. We designed an IVR rehabilitation game for neglect patients using the Oculus Rift. Multisensory cues were presented in the neglected visual field in a patient-tailored way. We acquired pilot data in 15 neurologically healthy controls and 7 stroke patients. First, we compared cybersickness before and after VR exposure. Second, we assessed the user experience through a questionnaire. Third, we tested whether neglect symptoms corresponded between the VR game and a computerized cancelation task. Fourth, we evaluated the effect of the multisensory cueing on target discrimination. Last, we tested two algorithms to tailor the game to the characteristics of the neglected visual field. Cybersickness significantly reduced after VR exposure in six stroke patients and was low in healthy controls. Patients rated the user experience neutral to positive. In addition, neglect symptoms were consistent between a computerized cancelation and VR rehabilitation task. The multisensory cue positively affected target discrimination in the game and we successfully presented sensory stimulation to the neglected visual field in a patient-tailored way. Our results show that it is promising to use gamified patient-tailored immersive VR for neglect rehabilitation.
Prevalence of bacterial contamination in uncooked sticky rice samples from markets in Japan

We investigated the prevalence of bacterial contamination in uncooked sticky rice samples obtained from markets in Japan. Between June and August, 2019, a total of 25 sticky rice samples were purchased from shops in the Tokyo area. Twenty-two (88.0%) and 10 (40.0%) of 25 sticky rice samples harbored 3.06±0.54 log spc/g of standard plates counts and 2.17±0.23 log cfu/g of enterobacteriaceae bacteria counts, respectively. Three species of Enterobacteriaceae, Pantoea dispersa, P. ananati, and Kosakonia cowanii, were identified by MALDI-TOFMS-based test. Three (12.0%) of 25 sticky rice samples harbored 2.00 log cfu/g of Bacillus species. Bacillus spp. was not isolated after heat treatment (98 °C for 20 min.) of sample homogenates. Two isolates were identified B. cereus by both API 50 CH and MALDI-TOFMS based test. However, one isolate was B. mycoides by API 50 CH, but B. cereus by MALDI-TOF MS based test. These 3 Bacillus strains harbored no gene encoding the enzyme responsible for cereulide synthesis and had not produced enterotoxin. Our study suggested that some uncooked sticky rice has Enterobacteriaceae bacteria and Bacillus spp. contamination, however there is no isolate from heat treatment samples in this study. Isolated P. dispersa, P. ananati, and K. cowanii, are usually in the environment and these organisms have been isolated from patients with opportunistic infections. Preventing cross-contamination, from sticky rice to cooked food may be important during preparation and storage in kitchen.

Effect of Medicinal Plant Extract Incorporated Carrageenan Based Films on Shelf-Life of Chicken Breast Meat

This study was performed to examine the possibility of water extracts for several medicinal plants, such as Amomum tsaoko, Alpinia oxyphylla, and Citrus unshiu, as an active packaging ingredient for prevention of lipid oxidation. Chicken breast meats were packed with medicinal plant extracts incorporated carrageenan based films and their physico-chemical and microbial properties during storage at 5 o C were investigated. In chicken meat samples packed with A. tsao-ko (TF) or A. oxyphylla (OF) extract incorporated carrageenan based films, pH value, thiobarbituric acid reactive substances (TBARS), and the population of total microbes were significantly lower than those of the negative control (film of no extract was incorporated, CF) after 5 d of storage (p<0.05). Especially, TBARS value of TF (0.12±0.01 mg malonaldehyde/kg meat) was significantly lower than chicken meat samples packed with positive control (ascorbic acid incorporated film, AF, 0.16±0.01 mg malonaldehyde/kg meat) at 3 d of storage, and it means TF has enough antioxidative activity to prevent the lipid oxidation of chicken meat. However, there was no consistent effect on VBN values of chicken meats packed with medicinal plant extracts incorporated films during storage. Based on the obtained results, it is considered that A. tsao-ko extract has potential for being used as a natural antioxidant ingredient in active packaging areas.
The effect of working memory capacity on word recognition speed in Arabic

The current study examined the effect of working memory capacity (WMC) on word recognition speed (WRS) in Arabic second grade readers. We start from the hypothesis that WRS performance depends on WMC. Two groups of good and poor readers were tested on measures of WMC and WRS.The results show that high working memory (WM) span readers are more rapid in word recognition (WR) than low WM span readers. We found also high correlations between WMC and WRS, which means that WMC can be a good predictor of word recognition ability in Arabic orthography.
Film Deposition by Molecular-Beam Techniques

A review of molecular-beam epitaxy of GaAs and the observation of surface structures with high-energy electron diffraction in an ultrahigh-vacuum system is described. The utilization of these surface structures as growth conditions to produce n- and p-type layers when doped with Sn, Ge, and Mg, and the electrical and optical evaluations of the layers thus grown is also discussed. The molecular-beam epitaxy method may be used to fabricate extremely thin multilayer structures and may play an increasing role in semiconductor technology.

Despite recommendations of snare polypectomy for small polyps (6-9mm) almost half of them are resected by forceps. The aim of this study was to analyse if the publication of clinical data or guideline have more impact on the reduction of the forceps resection rate of polyps ≥5mm.
Legal Origin and Islamic Finance Development: why does Sharia matter?

Previous studies on financial development have shown that differences in legal origin explain differences in financial development. Using historical comparisons and cross-country regressions for 40 countries observed for the period from 2005 to 2018, our research try to assess how different legal origins affected the development of Islamic finance worldwide. More particularly, our research assess empirically why and how Sharia adopted wholly or partially (combined with Common or Civil Law) could explain the level of development of Islamic finance in different jurisdictions. Our primary results, shown that countries adopting a Sharia legal system had a very well developed Islamic financial system. Moreover, countries, adopting a mixed legal system based on Common Law and Sharia Law, were characterized by the flexibility of their legal systems to make changes to their laws in response to the changing socioeconomic conditions and that these helped the development of the Islamic financial industry. However, countries, adopting a mixed legal system based on both Civil Law and Sharia Law, were less flexible in making changes to their old laws and this thwarted the development of the Islamic financial industry in these countries. Furthermore, we found that the concentration of Muslim population (the percentage of Muslim population) had a positive effect on the development of the Islamic banking assets. Also, the level of income had a positive and significant effect on the development of Islamic.
