Predicting the Culturally Responsive Teacher Roles With Cultural Intelligence and Self-Efficacy Using Machine Learning Classification Algorithms

This study aimed to predict the culturally responsive teacher roles based on cultural intelligence and self-efficacy using machine learning classification algorithms. The research group consists of 415 teachers from different branches. The Bayes classifier (NaiveBayes), logistic-regression (SMO), lazy-classifier (KStar), meta-classifier (LogitBoost), rule-learner (JRip), and decision-tree (J48) were employed in the assessment of the predictive model. The results indicated that JRip rule-learner had a better performance than other classifiers in predicting the culturally responsive teachers based on six attributes used in the study. The JRip rule-learner classified the culturally responsive teachers as low, medium, or high with an accuracy of 99.76% (CCI: 414/415) [Kappa statistic: 0.996, Mean Absolute Error (MAE): 0.003, Root Mean Square Error (RMSE): 0.043, Relative Absolute Error (RAE): 0.663, Relative Squared Error (RRSE): 9.244]. The results indicated that all classifiers had an acceptable performance but JRip rule-learner had a better performance than the other classifiers in predicting the culturally responsive teachers.
A wolf in (black) sheep’s clothing? Subjective group dynamics in sports fans

ABSTRACT Extant research has characterised various group behaviours through the lens of the theory of subjective group dynamics, which describes how ingroup members’ deviation from the group’s prescriptive norms can impact other members’ perceptions of the group and its members. Deviations from ingroup norms may result in the black sheep effect, which refers to the tendency for individuals to actively judge deviant ingroup members more harshly than similar behaving outgroup members. In this study, we examined the black sheep effect in the context of sports fans’ judgments about athletic performance. When athletes violate sports fans’ prescriptive team norms by performing poorly, these fans may derogate such athletes. Subjective group dynamics in sports contexts has been understudied, and findings for the black sheep effect have been mixed. Thus, we empirically tested for these phenomena in two experiments using fictitious cases of ingroup and outgroup athlete performances. In line with predictions from subjective group dynamics, we found a lack of ingroup bias on perceived competence and increased identity threat following poor performance, with team identification moderating such outcomes in Study 1. Although the presence of the black sheep effect was not confirmed in Study 2, our second experiment offers evidence to suggest that fans may equate poor-performing, ingroup athletes with similar outgroup players. Limitations and future directions for research are discussed.
Multi-Physical and Electrochemical Coupling Model for the Protonic Ceramic Fuel Cells with H+/e−/O2− Mixed Conducting Cathodes

A protonic ceramic fuel cell (PCFC) has great potential for medium temperature power generation. Its working process, however, is complicated and quite different from the traditional oxygen ionic solid oxide fuel cell (O2−-SOFC) and proton exchange membrane fuel cell (PEMFC). In this paper, a multi-physical model for the PCFC with H+/e−/O2− mixed conducting cathode is established, in which the fuel- and oxidant-diffusing processes; electron-, oxygen ion-, and proton-conducting processes; three electrochemical reactions; and their coupling working details are carefully considered. Taking Ni-BZCY/BZCY/BZCY-LSCF PCFC as an example, the validation of the model is well verified by good agreements with the experiment iop-Vop curves at different temperatures. The result shows that the cathodic electrochemical reactions will be concentrated to a small thickness near the electrolyte because of the greatly decreased ionic conductivity compared with the high electronic conductivity at an intermediate temperature. O2− within the PCFC cathode is only an intermediate transform substance between the electrons and protons. Thus, there is a peak oxygen ion current distribution within the composite cathode of PCFC. The cathodic oxygen reduction half reaction is found to be a key factor to dominate the total PCFC voltage loss at the intermediate temperature zone. The concentration polarization of anode-supported PCFC is small, due to the vapors that are generated in the cathode side instead of anode side.
Endoscopic Laser-Based 3D Imaging for Functional Voice Diagnostics

Recently, we reported on the in vivo application of a miniaturized measuring device for 3D visualization of the superior vocal fold vibrations from high-speed recordings in combination with a laser projection unit (LPU). As a long-term vision for this proof of principle, we strive to integrate the further developed laserendoscopy as a diagnostic method in daily clinical routine. The new LPU mainly comprises a Nd:YAG laser source (532 nm/CW/2 ω ) and a diffractive optical element (DOE) generating a regular laser grid (31 × 31 laser points) that is projected on the vocal folds. By means of stereo triangulation, the 3D coordinates of the laser points are reconstructed from the endoscopic high-speed footage. The new design of the laserendoscope constitutes a compromise between robust image processing and laser safety regulations. The algorithms for calibration and analysis are now optimized with respect to their overall duration and the number of required interactions, which is objectively assessed using binary classifiers. The sensitivity and specificity of the calibration procedure are increased by 40.1% and 22.3%, which is statistically significant. The overall duration for the laser point detection is reduced by 41.9%. The suggested semi-automatic reconstruction software represents an important stepping-stone towards potential real time processing and a comprehensive, objective diagnostic tool of evidence-based medicine.
Recent Advances in Synergistic Antitumor Effects Exploited from the Inhibition of Ataxia Telangiectasia and RAD3-Related Protein Kinase (ATR)

As one of the key phosphatidylinositol 3-kinase-related kinases (PIKKs) family members, ataxia telangiectasia and RAD3-related protein kinase (ATR) is crucial in maintaining mammalian cell genomic integrity in DNA damage response (DDR) and repair pathways. Dysregulation of ATR has been found across different cancer types. In recent years, the inhibition of ATR has been proven to be effective in cancer therapy in preclinical and clinical studies. Importantly, tumor-specific alterations such as ATM loss and Cyclin E1 (CCNE1) amplification are more sensitive to ATR inhibition and are being exploited in synthetic lethality (SL) strategy. Besides SL, synergistic anticancer effects involving ATRi have been reported in an increasing number in recent years. This review focuses on the recent advances in different forms of synergistic antitumor effects, summarizes the pharmacological benefits and ongoing clinical trials behind the biological mechanism, and provides perspectives for future challenges and opportunities. The hope is to draw awareness to the community that targeting ATR should have great potential in developing effective anticancer medicines.
Partition Layout Loading of Frequency Selective Surface Absorbers on the Curved Surfaces for the Significant RCS Reduction

In this article, the significant radar cross section (RCS) reduction of curved surfaces in the low microwave frequency band is reported. The design method of partition layout loading of frequency selective surface (FSS) absorbers to control the surface current is put forward. Comparison of the scattering field intensities of different zones on the curved surface clearly shows that surface current should be suppressed in a large zone to effectively reduce the RCS of the curved surface at these frequencies. FSS absorbers under normal and 45° angle of incidence are designed and placed on the different zones of the curved surface to realize the partition layout loading, and remarkable RCS reduction has been obtained. Specifically, more than 15-dB RCS reduction is achieved in 1.05–1.45 GHz, and absorption above 90% is obtained from 0.95 to 1.5 GHz for TE polarization. The great agreement between the simulated and measured results validates the proposed design method.
Transport of Acrosomal Enzymes by KIFC1 via the Acroframosomal Cytoskeleton during Spermatogenesis in Macrobrachium rosenbergii (Crustacea, Decapoda, Malacostracea)

Simple Summary In crustaceans, the sperm have no tail, and spermatogenesis consists only of acrosomal formation and nuclear deformation. The mechanism of acrosome formation during spermatogenesis of Macrobrachium rosenbergii is one of the hot topics in reproductive biology. Many motor proteins are involved in spermatogenesis. KIFC1, as a member of the kinesin family, is one of the motor proteins that our lab has been focusing on. The acrosome contains a large number of acrosomal enzymes for the hydrolysis of the egg envelope. In order to understand how these acrosomal enzymes are transported to the acrosome cap after synthesis, we cloned the KIFC1 and the Acrosin of M. rosenbergii. By detecting the localization of KIFC1 and Acrosin, we found that Mr-KIFC1 may be involved in acrosomal enzyme transport during spermiogenesis of M. rosenbergii. This study is to propose the function of KIFC1 to transport acrosomal enzymes along the acroframosome structure during crustacean spermatogenesis. Abstract The spermatogenesis of crustaceans includes nuclear deformation and acrosome formation. The mechanism of acrosome formation is one focus of reproductive biology. In this study, Macrobrachium rosenbergii was selected as the research object to explore the mechanism of acrosome formation. The acrosome contains a large number of acrosomal enzymes for the hydrolysis of the egg envelope. How these acrosomal enzymes are transported to the acrosomal site after synthesis is the key scientific question of this study. The acroframosome (AFS) structure of caridean sperm has been reported. We hypothesized that acrosomal enzymes may be transported along the AFS framework to the acrosome by motor proteins. To study this hypothesis, we obtained the full-length cDNA sequences of Mr-kifc1 and Mr-Acrosin from the testis of M. rosenbergii. The Mr-kifc1 and Mr-Acrosin mRNA expression levels were highest in testis. We detected the distribution of Mr-KIFC1 and its colocalization with Mr-Acrosin during spermatogenesis by immunofluorescence. The colocalization of Mr-KIFC1 and microtubule indicated that Mr-KIFC1 may participate in sperm acrosome formation and nucleus maturation. The colocalization of Mr-KIFC1 and Mr-Acrosin indicated that Mr-KIFC1 may be involved in Acrosin transport during spermiogenesis of M. rosenbergii. These results suggest that Mr-KIFC1 may be involved in acrosomal enzymes transport during spermiogenesis of M. rosenbergii.
Liquidity, Credit Risk, and Their Interaction on the Spreads in China’s Corporate Bond Market

This paper investigates the impact of multidimension liquidity, credit risk, and the interaction between liquidity and credit risk on corporate bond spreads based on a large transaction data set from July, 2006 to June, 2016, including the monthly data of 3716 bonds in China. Our main findings reveal that liquidity premiums are the main parts of corporate bond spreads. The interaction between liquidity and credit risk plays a significant role in determining corporate bond spreads. In addition, the differences between the interbank market and the exchange market have a significant impact on corporate bond spreads in normal period, and the interaction between liquidity and credit risk has an enhanced impact on corporate bond spreads during financial crisis. We also find that the interaction between liquidity and credit risk will increase with the increase of liquidity risk and credit risk and it is a time-varying dynamic process.
Improving Permeability of Ferrite Cores Used in Switch-mode Power Supplies

In this study two methods are proposed to increase the permeability of ferrite cores used in switch-mode power supply applications. The first method is based on the principle of magnetic shaking where an AC magnetic field is superposed on the magnetic core. This method yields good performance in shielding applications but still facing some technical difficulties in switch-mode power supply applications. The second method is based on superimposing a DC magnetic field component equivalent to the main DC component flowing in the main winding of the switch-mode power supply. This method is verified to reduce the power supply inductor current ripple by 68% while downsizing the core of the winding.
Asynchronous Instructional Videos During COVID-19 Emergency Remote Teaching: Student Experiences Within a New Zealand ITP

The COVID-19 pandemic created unprecedented challenges for tertiary education institutions worldwide. The crisis placed enormous pressure on educational institutions as they were required to pivot suddenly to teaching fully online. In New Zealand, Tertiary Education Organisations (TEOs) were forced to close on Wednesday 25 March 2020 after New Zealand moved to Alert Level 4, necessitating the sudden implementation of online teaching. The purpose of this study is to investigate the effectiveness of pre-recorded instructional videos in three selected courses taught by a tertiary education institution, a member of the Institutes of Technology and Polytechnics (ITPs) New Zealand.
Squamous Metaplasia of the Colon Following Severe COVID-19

A 53-year-old man was admitted for respiratory failure due to severe acute respiratory syndrome caused by a severe acute respiratory syndrome coronavirus 2 infection. The patient required prolonged artificial ventilation and extracorporeal membrane oxygenation (ECMO) for respiratory support. Despite successful discontinuation of ECMO, the patient experienced profuse watery diarrhea (5-10 L/day). A colonoscopy revealed an inflamed surface without undulation that uniformly extended throughout the colon. Biopsy specimens revealed complete disappearance of existing crypts and replacement with squamous or transitional epithelium normally observed in the anal transitional zone mucosa, with granulation tissue proliferation in the lamina propria. Watery diarrhea persisted despite corticosteroid and infliximab administration. Although diarrhea due to atrophy of the surface and cryptic epithelium as an intestinal manifestation of coronavirus disease 2019 usually responds to corticosteroids, refractory diarrhea can be attributed to squamous metaplasia with complete disappearance of the surface and cryptic epithelium.

Purpose: The main objective of the study was to establish the influence of computer technology on the competitive advantage of selected media houses in Kenya.Methodology: The study adopted a descriptive research design. Findings: Results revealed that adoption of computer technology influenced the competitive advantage of selected media houses in Kenya. Therefore, the study concluded that computer technology influenced the competitive advantage of selected media houses in Kenya. The conclusion was informed by the realization that computerized software adoption, online mobile application and use of internet influenced the competitive advantage of selected media houses in Kenya. The study also concluded that staff training had a moderating effect on the relationship between technology and competitive advantage of selected media houses in Kenya.Unique contribution to theory, practice and policy: The study would be of value to the media industry in Kenya. This is due to the fact that the media industry has experienced increased competition from new media such as the internet and social media making the competition stiffer and survival harder. The study would therefore provide relevant information to these media houses on how computer technology affects their competitive advantage. Hence, this information can give the media houses insight on which strategies to adopt so as to ensure competitiveness. Consumers of media would benefit from this study as the study creates awareness that use of new media is cheaper. This would also assist to increase the adoption of technology in Kenya.

The Interplay Between Economic Freedom and Tax Revenue Performance: Panel Evidence from SADC

This study aims to scrutinize the interplay between economic freedom and tax revenue performance in 14 SADC countries. The study makes use of dynamic panel data spanning from 2000 – 2017 with 238 year-country observations. The econometric modeling applied includes Generalized Methods of Moments and Cross-country Correlations. The dynamic panel estimation results indicate that both conventional and unconventional determinants of tax revenue mobilization are statistically significant in explaining variations in tax revenue performance. In contrast to earlier studies, the researcher found that economic freedom exhibits a negative impact on tax revenue mobilization. These findings can be based on the assumption that African countries are characterized by agrarian activities which take place in the informal sector and are thus are difficult to regulate and tax. As a result, the benefits of economic freedom cannot be fully realized. The policy implication is for African countries to invest substantially in the manufacturing sector to increase tax revenue and eliminate the substantial informal sector. Further to this, governments in SADC countries should focus more on reducing red tape and unnecessary bureaucracy to enhance the ease of doing business and realize the full benefits of economic freedom.
Detection and numerical simulation of optoacoustic near- and farfield signals observed in PVA hydrogel phantoms

We present numerical simulations for modelling optoacoustic (OA) signals observed in PVA hydrogel tissue phantoms. We review the computational approach to model the underlying mechanisms, i.e. optical absorption of laser energy and acoustic propagation of mechanical stress, geared towards experiments that involve absorbing media only. We apply the numerical procedure to model signals observed in the acoustic near- and farfield in both, forward and backward detection mode, in PVA hydrogel tissue phantoms (i.e. an elastic solid). Further, we illustrate the computational approach by modeling OA signal for several experiments on dye solution (i.e. a liquid) reported in the literature, and benchmark the research code by comparing our fully 3D procedure to limiting cases described in terms of effectively 1D approaches.

Water and nutrient economy in vegetable crops through drip fertigation and mulching techniques: a review

Abstract Vegetables are important constituents of Indian agriculture and nutritional security of the people. India no doubt has diverse agro-climatic conditions with distinct seasons that are supportive for growing a wide range of vegetables and offers a lot of potential to enhance their production by adopting innovative technologies. Despite largest irrigation network in India, irrigation efficiency is merely 40% and water and nutrient use efficiencies are very low. Also bringing more area under irrigation will largely depend upon the efficient use of water and other resources. In this context, micro irrigation with fertigation especially in vegetable crops has proven a win-win technology in enhancing water and nutrient use efficiencies and in turn higher yield potential thereby achieving the prime objective of ‘more crop per drop’. The technology provides precise water control, dissolved fertilizers, application facilities and thus more resilient and cost effective. Moreover, mulching along with drip irrigation and fertigation add feather to this technology by controlling weed population and increasing overall efficiency of the system. Mulching insulates the soil, provides a buffer from cold and hot temperature, reduce deterioration and erosion of soil and also checks water evaporation. This review presents the finding of various researchers involving the influence of drip irrigation, fertigation and mulching on different vegetable crops. It is evident from the studies that drip fertigation practice alone or in combination with mulching offer a huge potential in enhancing crop yields, quality, growth, water and nutrient saving in comparison with other conventional tools of irrigation and fertilization.
Performance trade-offs in reconfigurable networks for HPC

Designing efficient interconnects to support high-bandwidth and low-latency communication is critical toward realizing high performance computing (HPC) and data center (DC) systems in the exascale era. At extreme computing scales, providing the requisite bandwidth through overprovisioning becomes impractical. These challenges have motivated studies exploring reconfigurable network architectures that can adapt to traffic patterns at runtime using optical circuit switching. Despite the plethora of proposed architectures, surprisingly little is known about the relative performances and trade-offs among different reconfigurable network designs. We aim to bridge this gap by tackling two key issues in reconfigurable network design. First, we study how cost, power consumption, network performance, and scalability vary based on optical circuit switch (OCS) placement in the physical topology. Specifically, we consider two classes of reconfigurable architectures: one that places OCSs between top-of-rack (ToR) switches—ToR-reconfigurable networks (TRNs)—and one that places OCSs between pods of racks—pod-reconfigurable networks (PRNs). Second, we tackle the effects of reconfiguration frequency on network performance. Our results, based on network simulations driven by real HPC and DC workloads, show that while TRNs are optimized for low fan-out communication patterns, they are less suited for carrying high fan-out workloads. PRNs exhibit better overall trade-off, capable of performing comparably to a fully non-blocking fat tree for low fan-out workloads, and significantly outperform TRNs for high fan-out communication patterns.
