Determining Factors Affecting International Students’ Satisfaction among Iranian Medical Sciences Universities: A Qualitative Study

Introduction One of the main pillars of competition among higher education institutions around the world in the field of internationalization is attracting more international students. In this competitive market, universities of various countries have realized that innovative marketing and strategic arts are vitally important in attracting and retaining a higher number of international students. On the other hand, more than any other time, students seek to gain a high-quality international educational experience that would ultimately lead to an opportunity for a better life and occupation and even long-term immigration (1). One of the benefits of accepting international students is a contribution to the economy of the country since these individuals have a considerable economic share in the destination country through life costs and registration fees (2). For instance, the international education industry accounts for 15% of the revenue of Australian universities, which is the third export revenue source in Australia (2). Australia’s sector of international development programs has anticipated global demand for international education in about 7.2 million students by 2025 (3). This intense competition among higher education institutions in global markets is one of the globalization challenges that requires taking students’ satisfaction into account as customers and monitoring their needs (4). Customer orientation is so important that has led to fierce competition among organizations (5). In addition, student satisfaction has been identified as an important factor for maintaining universities and institutes’ ability to attract students (6). In this respect, student satisfaction depends on certain conditions and factors that exist in the university. Given the fact that student satisfaction is a complex structure and has no single global definition, researchers have generally defined this notion as the result of students' mental evaluation of the different results and experiences related to their educational environment services. Meanwhile, the educational environment’s support is very important in their academic success (7).

Changes of Morphology and Capping of Model Transition Metal Clusters

We investigate changes of morphology between icosahedra, cuboctahedra, and decahedra in transition metal clusters containing 13, 55, and 147 atoms modeled by two different classes of empirical potential. Highly cooperative processes exist which lead to a fundamental change in structure via a single transition state. As the size increases, these pathways break down into a series of steps, and intermediate stationary points appear; this happens at smaller size for clusters described by the Sutton−Chen potentials. Comparison of our calculated barriers and rates with previous results from electron microscopy and calculations of diffusion and interlayer transport mechanisms generally gives qualitative agreement. However, neither potential predicts that Au55 or Au147 cuboctahedra will be observable experimentally. A combination of substrate interaction and capping probably explains this discrepancy. Finally, we predict that the icosahedral morphology is likely to be ‘frozen in' at relatively low particle size a.
Curriculum Contents of Entrepreneurship Programme and Its Impact on Basic Students’ Skills Acquisition in Entrepreneurship in Benue State Nigeria

This study investigated curriculum content of entrepreneurship education programme and its impact on Upper Basic students’ skill acquisition in entrepreneurship education in Education Zone A of Benue State, Nigeria. The study was guided by eight research questions and six hypotheses. The study adopted both survey and quasi-experimental design of non-randomized pretest-posttest control type to address the objectives. The population for the study comprised 24,110 Upper Basic III students during the 2018/2019 academic session. The sample consisted of 243 students drawn from six schools out of 369 secondary school using purposive sampling technique. Curriculum Content for Entrepreneurship Centres, (CCEC), Prevocational Studies Curriculum Content Analysis (PSCCA) and Entrepreneurship Practical Skill Acquisition Test (EPSAT) were used for data collection. The instruments were validated for face and content validity by three experts in the fields of measurement and evaluation, curriculum and instruction and entrepreneurship education. Kudar Richardson (K-20) formula was used to calculate the reliability coefficient of EPSAT and the result showed 0.66 while Cronbach Alpha was used to calculate the reliability coefficient of EIQ and the result showed 0.84. Mean and standard deviation were used to answer the research questions. Analysis of Covariance (ANCOVA) was used to test the null hypotheses at 0.05 level of significance. The findings revealed that entrepreneurship centres in the study area do not have written curriculum and students were not sent to these centres for internship training. Another finding was that many topics in prevocational studies curriculum do not recommend practical teaching strategy and even those that recommended were not taught practically by the entrepreneurship education teachers. In addition, students that were taught entrepreneurship education (EE) through internship training acquired more skills (F=442.446; P=0.000 0.05. The findings also showed no significant interaction effect of strategy and gender on students’ skill acquisition in entrepreneurship education. Based on the findings, it was recommended among others that government should ensure that entrepreneurship centres have a documented curriculum and students should be sent to those centres for internship training. Also, prevocational studies curriculum should be reviewed to ensure a more practical-oriented content and that entrepreneurship education teachers should be trained and encouraged to take students to internship training.
All-Electrical Control of Scaled Spin Logic Devices Based on Domain Wall Motion

Spin logic devices based on domain wall (DW) motion offer flexible architectures to store and carry logic information in a circuit. In this device concept, information is encoded in the magnetic state of a magnetic track shared by multiple magnetic tunnel junctions (MTJs) and is processed by DW motion. Here, we demonstrate that all-electrical control of such nanoscale DW-based logic devices can be realized using a novel MTJ stack. In addition to field-driven motion, which is isotropic, we show the directional motion of DWs driven by current, a key requirement for logic operation. Full electrical control of an AND logic gate using DW motion is demonstrated. Our devices are fabricated in imec’s 300-mm CMOS fab on full wafers, which clears the path for large-scale integration. This proof of concept, thus, offers potential solutions for high-performance and low-power DW-based devices for logic and neuromorphic applications.
The Effect of COVID-19 Stress on Sexual Compulsivity Symptom:The Mediating Role of Perceived Social Support

However, few study have investigated the effect and mechanism of the emergency COVID-19 on psychosexual behaviors during the COVID-19 outbreak in China. Thus, this primary objective of the research was to explore the links between COVID-19 stressing and sexual compulsive symptom, and perceived social support.Methods This study used a cross-design, 3219 undergraduate students were recruited online to complete all questionnaires. Results The obtained results conﬁrmed that COVID-19-stressing was correlated with perceive social support and sexual compulsive symptom, and perceived social support mediated the relation between COVID-19-stressing and sexual compulsive symptom; and gender moderated the link of COVID-19-stressing and perceive social support. In addition, in the case of the individuals’ sexual compulsive symptom, the regression analyses showed that COVID-19-stressing and perceive social support were significantly predicted. Conclusions Thus, the findings extends previous knowledge and provide highlighted ideas, indicating that the COVID-19 not only affected individuals’ physical health, but also impacted their psychological behaviors and intention, such as sexual compulsive symptom. Moreover, the findings revealed that compared to the female, the male students would promoted higher perceived social support when COVID-19-stressing is boosting.Policy Implication It is important that individuals’ sexual psychology were cared via professional consulting during people are isolation for the emergent infection.
Design and Performances of a Carbon Monoxide Sensor Using Mid-Infrared Absorption Spectroscopy Technique at 4.6 µm

ABSTRACT Based on infrared absorption spectroscopy technique, a carbon monoxide sensor was developed using the fundamental absorption band of carbon monoxide molecule at the wavelength around 4.6 µm. The developed sensor consists of pulse-modulated wideband incandescence, open ellipsoid light-collector gas-cell, dual-channel detector, and control and signal-processing module. With the prepared standard carbon monoxide gas sample, sensing characteristics on carbon monoxide were investigated using the sensor. Experimental results reveal that the limit of detection is about 10 ppm, the relative error at the limit of detection point is less than 14%, and that is less than 7.8% within the low concentration range of 20∼180 ppm. The maximum absolute errors of 50 min long-term measurement on the 0 and 14 ppm CO gas samples are about 3 and 3.17 ppm, respectively, and the standard deviations are as small as 0.18 and 1.25 ppm, respectively. Compared with the reported carbon monoxide detection systems utilizing quantum cascaded lasers and distributed feedback lasers, the proposed sensor shows potential applications in carbon monoxide detection under the circumstances of coal-mine and environmental protection, by virtue of high performance, low cost, simple optical structure, and so on.
Effects of Packaging Method on Salt-Cured Cod Yield and Quality During Storage

Different packaging conditions of salt-cured cod fillets were studied during 2-years chilled storage. Yield and quality of salt-cured Atlantic cod fillets packed in sealed polystyrene boxes or in traditional cardboard boxes were compared. After 4 months, yield decreased by approximately 10% and decreased further when packed in cardboard boxes. Lipid oxidation was low after 12 months, and no microbiological spoilage was registered. The total amount of bacteria in the fish reduced with storage time, independent of packaging. The reddish color of halophilic bacteria was detected after 7–8 weeks at 18°C, but not if packed with MAP.
Access Control Method for the Offline Home Automation System

—The paper proposes a Decision Support System for controlling access to the core functionalities of speech-based, embedded home automation devices working fully ofﬂine. The system is based on the Keyword Spotting technology recognizing custom keywords from a non-English language. Even though the performance of this technology in the scientiﬁc set-ups is relatively high, the reported false positive rates are still not sufﬁcient for commercial application. Therefore, in our solution, we incorporate a number of computationally lightweight modules that considerably reduce the rate of false alarms while retaining an acceptable access rate.
Characterization, antibiogram and biofilm forming potential of cariogenic bacteria isolated from dental plaque of patients with cardiovascular diseases.

Introduction: Periodontal diseases remain one of the major intractable risk factor for the development of the cardiovascular diseases (CVD), such as atherosclerosis and infective endocarditis; therefore, exploring the links in between oral cavity hygiene and its association with the atherosclerosis vis-a-vis heart infarction, stroke and peripheral vascular disease is absolutely crucial. Methodology: In this study, we collected 200 dental plaque samples from cardiac patients. The samples were used to evaluate the burden of carcinogenic bacteria in patients suffering from CVD. Additionally, the antibiotic resistance/susceptibility pattern and biofilm forming potential of the isolates were also determined. Finally, the antimicrobial potential of three most common active ingredients of the mouth washes (Triclosan, Chlorhexidine, and Benzadine) was tested against the isolated cariogenic bacteria. Results: We found Streptococcus sangius and Streptococcus mutans to be the most common bacteria in cardiac patients. Most of these isolates (70%) were resistant to one or more commonly used antibiotic such as Ampicillin, Gentamycin, Cefixime, Ofloxacin, and Erythromycin. Additionally, most of the isolates were found to be dominant biofilm former. Finally, the antimicrobial activity of mouth rinses, containing Triclosan, chlorhexidine, and Benzadine against our clinical isolates showed better and consistent sensitivity patterns as compared with the tested antibiotics, where 60-70% of the isolates were found to be sensitive to the active agents. Conclusion: Our results revealed the presence of multi-drug resistant bacteria in oral cavity of patients suffering from CVD. The isolates were, however, sensitive to agents present in mouth washes, and hence this study supports the recommendations to use mouth rinses in cardiovascular patients especially with infective endocarditis with poor dental hygiene.
Push−Pull Arylethynyl Porphyrins: New Chromophores That Exhibit Large Molecular First-Order Hyperpolarizabilities

A new class of chromophores has been fabricated that features both electron-releasing and electron-withdrawing groups fused via an intervening ethynyl moiety to the carbon framework of a (porphinato)metal complex. These species possess large molecular first-order hyperpolarizabilities (β). We report herein the synthesis, optical spectroscopy, and the hyper-Rayleigh scattering data used to determine the β values of two archetypal members of this new class of exceptional nonlinear chromophores: [5-[[4‘-(dimethylamino)phenyl]ethynyl]-15-[(4‘‘-nitrophenyl)ethynyl]-10,20-diphenylporphinato]copper(II) and [5-[[4‘-(dimethylamino)phenyl]ethynyl]-15-[(4‘‘-nitrophenyl)ethynyl]-10,20-diphenylporphinato]zinc(II). One of these compounds, [5-[[4‘-(dimethylamino)phenyl]ethynyl]-15-[(4‘‘-nitrophenyl)ethynyl]-10,20-diphenylporphinato]zinc(II), possesses β values near 5000 × 10-30 esu at incident irradiation wavelengths of both 830 and 1064 nm. These studies suggest that this chromophoric structural motif may find utility.
The Role of School Administrative Support and Primary School Teachers’ ICT Literacy to Integrate ICT into the Classrooms in Pahang, Malaysia

This study aimed to look at the role of information and communications technology (ICT) literacy of teachers as a mediator between the school administrative support and ICT competence of primary school teachers in Pahang. The researchers developed a mediation model based on relevant literature reviews and subsequently tested the model. This study used a total survey design. The researchers employed stratified cluster sampling to select the pilot study and the actual study samples randomly. A total of 514 teachers were involved in the pilot study and 530 teachers were involved in the actual study. The Cronbach's alpha for instrument was . 954 while the validity of the instrument used was determined using the SEM-AMOS method. The results based on the pilot data indicated a good model fit with chi-square = 212.406, df = 111, p < . 001, CMIN/ df = 3.662, GFI = . 938, CFI = . 941, and RMSEA = . 072, whereas results based on the actual study also indicated a good model fit with chi-square = 204.839, df = 58, p < . 001, CMIN/ df = 3.532, GFI = . 942, CFI = . 950, and RMSEA = . 069. The findings showed that there were direct and indirect effects of school administrative support and teachers ’ ICT literacy on teacher s’ ICT competences. There was a statistically significant relationship ( p < .05 ) between school administrative support and teacher s’ ICT competence and an indirect effect through teacher s’ ICT literacy as a mediator. Hence, teachers ’ ICT literacy acts a partial mediator in the model. This study shows that school administrative support and teacher s’ ICT literacy play an important role in shaping teacher s’ ICT competence. Furthermore, the study provides further evidence that school principals through teacher s’ ICT literacy play an important role in integrating ICT into the classroom. School administrators should equip themselves with formal training in technological leadership so that they can better contribute to aiding school teachers to better integrate ICT into their teaching and learning.
Optical Studies of CaS:Eu, Sm Infrared Stimulable Phosphors

The photoluminescence (PL) and infrared stimulated luminescence (ISL) spectra of CaS:Eu,Sm infrared stimulable phosphors (ISPs) are studied. In addition, the concentration dependence of ISL intensity is examined. Sm3+- and Eu2+-related structures are found in both the PL excitation and emission spectra. Two types of Sm3+ are found, one of which exhibits strong emission at around 650 nm and the other, weak emission compared to the other emissions at around 565 nm and 605 nm. These are assigned to an asymmetric and a symmetric site, respectively. ISL excitation spectra coincide with the Eu2+ 4f7 to 4f65d1 and 4f66s1 transitions and range from 220 to 650 nm. ISL emission spectra coincide with the Eu2+ 4f65d1 to 4f7 transition and range from 550 to 750 nm. ISL stimulation spectra range from 0.8 µm to 1.7 µm and are thought to indicate the Sm2+ ion transition from 4f6 to 4f55d1. The maximum ISL intensity is obtained from a sample with Eu and Sm concentrations of 500 and 130 ppm, respectively.
Multicolor electrochromic polyaniline–WO3 hybrid thin films: One-pot molecular assembling synthesis

Nanostructured polyaniline (PANI)–WO3 hybrid thin films were synthesized via a molecular assembling route in a solution of aniline using peroxotungstic acid (PTA) as the dopant and ammonium persulfate as the oxidant. The films show a porous morphology with nanorod arrays on the surface, and WO3 is uniformly incorporated into the polymer network. Electrochemical and electrochromic tests including cyclic voltammetry, chronoamperometry and corresponding in situ transmittance of PANI–WO3 hybrid films compared with neat PANI film and sol–gel WO3 film were conducted in 0.5 M sulfuric acid solution. The hybrid films, being a dual electrochromic material, varied from royal purple to green, pale yellow and finally dark blue as the applied potential was scanned from 0.8 V to −0.5 V. Compared to sulfate doped PANI film, high colouration efficiency and comparable durability are obtained in the PANI–WO3 hybrid films. The PANI–WO3 hybrid films also show faster switching speed and better durability than WO3 film. The enhanced electrochromic properties such as faster switching speed and better durability are mainly attributed to the combining of advantages of both materials and the formation of the donor–acceptor system.
Electronic structure of GaInN semiconductors investigated by x-ray absorption spectroscopy

We have investigated the electronic structure of GaInN semiconductors by performing x-ray absorption near-edge fine structure (XANES) spectroscopy at Ga K-edge and self-consistent-field real-space multiple-scattering theory calculations. It was demonstrated that the nondestructive Ga K-edge XANES spectra can be used as the fingerprints of structure and composition for GaInN. The theoretical calculations gave a reasonable reproduction of the experimental spectral features. The results revealed that the combination of the experimental XANES and the theoretical calculations is a powerful tool for studying the electronic structure of GaInN semiconductors.
Hydrogen Production and Carbon Formation during the Steam Reformer of Heptane in a Novel Circulating Fluidized Bed Membrane Reformer

Hydrogen production and carbon formation during the steam reforming of heptane over nickel-based catalyst are investigated in a circulating fluidized bed membrane reformer (CFBMR) at 723−823 K and 101.3−2026 kPa. A random carbon deposition and catalyst deactivation model is developed to account for the effect of carbon deposition on the overall reforming kinetics. The results show that the deposited carbon can be efficiently gasified by steam, hydrogen, carbon dioxide, or oxygen in this novel CFBMR, making carbon-free operation practically possible, especially when steam to carbon feed ratio is higher than 2.5 mol/mol. The use of hydrogen permselective membranes breaks the equilibrium barriers associated with the reversible re-forming reactions and increases the hydrogen yield significantly. The introduction of oxygen into the adiabatic reformer can efficiently supply the heat necessary for the endothermic steam reforming through the exothermic oxidation, making an autothermal condition possible for the e.
Domain Structure in Model Membrane Bilayers Investigated by Simultaneous Atomic Force Microscopy and Fluorescence Imaging

Simultaneous atomic force microscope (AFM) and submicron confocal fluorescence imaging of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid domain structures in 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) is presented. Lipids labeled by fluorescent probes either at the headgroups or tailgroups enable domain contrast in fluorescence imaging on the basis of partitioning between the gel (DPPC) and disordered liquid (DOPC) phases. However, correlation with AFM topographic information reveals that they do not always faithfully report exact gel domain size or shape. Furthermore, we find that the fluorescence contrast decreases significantly with domain size, such that small domains observed with AFM are not observed in fluorescence images despite adequate optical resolution. We attribute these effects in part to broadened partitioning of the probe lipids across the domain boundaries. Binding of fluorescent Alexa 488-conjugated cholera toxin B subunits to GM1 gangliosides in DPPC domains correlates we.
