Výuka odborného cizího jazyka na SOŠ a SOU (na příkladu stavebních a dřevozpracujících oborů)

Cílem studie je analyzovat stav výuky odborného cizího jazyka (OCJ) na středních odborných školách a středních odborných učilištích na příkladu oborů stavebnictví a oborů zpracování dřeva. Dále pak analyzovat závěry strategických dokumentů a na základě výsledků kvalitativního výzkumu popsat aktuální stav výuky OCJ na konkrétních SOŠ a SOU a následně nastínit možná didaktická řešení. Výklady jsou konkretizovány na příkladech oborů stavebnictví (Instalatér, Zedník, Stavebnictví) a zpracování dřeva (Truhlář). Vzhledem ke stanoveným cílům studie a designu výzkumu, který se soustředí zejména na analýzu a mapování současné situace ve výuce odborného cizího jazyka na středních odborných školách, jsme si stanovili následující výzkumné otázky: Jaké metody a didaktické materiály jsou využívány k výuce OCJ? Na jaké bariéry pedagogičtí pracovníci při výuce OCJ narážejí? Prostřednictvím jaké podpory by bylo možné efektivitu výuky OCJ zvýšit? S ohledem na stanovené výzkumné otázky byl výzkum proveden kvalitativní formou metodou polostrukturovaného rozhovoru. Celkově se výzkumu zúčastnilo 51 učitelů z 10 různých škol. Během výzkumu byly prozkoumány strategické dokumenty, školní vzdělávací programy a relevantní učebnice FLSP s cílem (ne)potvrdit jejich (ne)vhodnost pro vyučující a studenty. Výsledky studie naznačují, že kvalita výuky OCJ na zkoumaných středních odborných školách a učilištích je nedostatečná. Didaktická efektivita, kterou je třeba nastavit, spočívá zejména v integraci komunikační kompetence a odborného obsahu, v důrazu na praktičnost a reálnou profesní komunikaci, využití prvků informálního učení a v neposlední řadě v implementaci strategií digitálního vzdělávání.
On English Teachers’ Beliefs about Learner Autonomy

More and more scholars attach importance to learner autonomy in the field of foreign language teaching. Since students’ autonomy is closely related to teachers’ beliefs about learner autonomy, they have been studied by most scholars. However, there are relatively few studies on primary school English teachers’ beliefs about learner autonomy. In order to fill this gap, this study mainly studied six primary school English teachers’ beliefs about learner autonomy in Huidong County through interview. It was found that teachers’ understanding of learner autonomy was relatively clear.
The Ginzburg temperature of ionic fluids revisited

Using the collective variables method we revisit the estimates of the Ginzburg temperature for the Coulomb-dominated models of ionic fluids. We consider the charge-asymmetric primitive model supplemented by short-range attractive interactions in the vicinity of the gas-liquid critical point. For this model, we derive the effective Ising-like $\phi^{4}$-model Hamiltonian expressed in terms of the collective variables describing the fluctuation modes of the total number density. We obtain the explicit expressions for all the Hamiltonian coefficients within the framework of the same approximation, namely, the one-loop approximation which produces the mean-field critical parameters. Based on this Hamiltonian, we consistently calculate the reduced Ginzburg temperature $t_{G}$ for both the pure Coulombic model (a restricted primitive model) and the pure solvophobic model (a hard-sphere square-well model) as well as for the model parameters ranging between these two limiting cases. Contrary to the previous theoretical estimates, we obtain the reduced Ginzburg temperature for the pure Coulombic model to be about 20 times smaller than for the pure solvophobic model. For the full model including the short-range attractive and long-range Coulomb interactions, we show that $t_{G}$ approaches the value found for the pure Coulombic model when the strength of the Coulomb interactions becomes large enough. Our results suggest a key role of the Coulomb interactions in the crossover behaviour observed experimentally in ionic fluids as well as confirm the Ising-like criticality in the Coulomb-dominated ionic systems.

The impacts of infectious disease pandemic on China’s edible vegetable oil futures markets: A long-term perspective

For the extremely important role of China in global edible vegetable oil market and its decisive measures in the epidemic controlling and stable economic recovery during the COVID-19 pandemic, the aim of this article is to inspect the quantitative impacts of infectious disease pandemic on the returns, volatilities and correlations of China's edible vegetable oil futures markets by using a DCC-MVGARCH-X model incorporating Baidu searching index as the proxy of pandemic severity. Our empirical results show that infectious disease pandemic does have significantly positive impacts on the returns and volatilities of China's soybean, canola and palm oil futures markets. Second, there are significant volatility spillover effects among the three vegetable oils, suggesting strong contagion effect from one oil market to the others. Third, soybean oil and palm oil show the largest correlation, while the dependence between canola oil and palm oil is the smallest one among the three pairwise correlations. Moreover, no matter to consider epidemic situation in China or in global environment, infectious disease pandemic has significant effects on these correlations.

Corporate Governance and Tax Compliance of Quoted Manufacturing Companies in Nigeria

This study examined the impact of corporate governance attributes on tax compliance of 40 quoted consumer and industrial companies in Nigeria. It also looked at whether tax compliance is influenced by board independence and board gender. A correlational research design was adopted to test the association between and among the variables. In addition, the corporate annual reports and website for the periods 2016-2020 were utilized as the main sources of secondary data. In testing the research hypotheses and to ascertain the significant effect of the variables, the study utilized panel estimation technique method of data analysis. The findings revealed a significant positive relationship between board independence, board gender and tax compliance. The study, therefore, recommended that the Nigerian consumer and industrial companies should increase the members of board in relation to their independence and gender diversity in order to enhance the level of tax compliance.

Cognitive Change Before Old Age (11 to 70) Predicts Cognitive Change During Old Age (70 to 82)

Identifying predictors of cognitive decline in old age helps us understand its mechanisms and identify those at greater risk. Here, we examined how cognitive change from ages 11 to 70 is associated with cognitive change at older ages (70 to 82 years) in the Lothian Birth Cohort 1936 longitudinal study (N = 1,091 at recruitment). Using latent-growth-curve models, we estimated rates of change from ages 70 to 82 in general cognitive ability (g) and in three cognitive domains: visuospatial, memory, and processing speed. We found that g accounted for 71.3% of interindividual change variance. Greater cognitive gain from ages 11 to 70 predicted slower decline in g over 12 subsequent years (β = 0.163, p = .001), independently of cognitive level in childhood and at age 70, and domain-specific change beyond g. These results contribute to the goal of identifying people at higher risk of age-related cognitive decline.
Model Predictive Variable Impedance Control of Manipulators for Adaptive Precision-Compliance Tradeoff

Impedance control (IC) is widely used in contact-rich manipulator tasks since it provides manipulators with both operation precision and contact compliance, and trades them off by impedance parameters. However, fixed impedance parameters limit the applicability of IC in complex tasks during which the focus on the operation precision or the contact compliance is variable, such as physical human–robot collaboration and complex assembly tasks. This article presents model predictive variable impedance control approaches for adaptive precision-compliance tradeoff to satisfy variable task requirements. Specifically, we establish a novel impedance model, which transforms the variable impedance law design problem into a control law design problem, and allows us to consider novel impedance constraints that can determine manipulators' extreme precision and compliance properties. According to whether state constraints are further considered, one-step (OS) and multistep (MS) model predictive control approaches are proposed to solve these transformed control problems, and the corresponding optimization problem of the OS MPC can be established as a QP problem due to the special form of the novel impedance model. A tank-based approach is further proposed to correct the variable impedance laws for the system passivity concern. Various comparative experiments are conducted to validate the effectiveness of the presented approaches.

An Acoustic 3-D Positioning System for Robots Operating Underground

Underground robots are potentially helpful in many application domains, including geotechnical engineering, agriculture, and archaeology. One of the critical challenges in developing underground robotics is the accurate estimation of the positions of the robots. Acoustic-based positioning systems have been explored for developing an underground 3-D positioning system. However, the positioning range is limited due to attenuation in the medium. This letter proposes an underground positioning system that utilizes a novel and easy-to-implement electronic approach for measuring the acoustic propagation times between multiple transmitters and a receiver. We demonstrate a prototype using four transmitters at the surface and a single buried acoustic sensor as a proof of concept. The times of arrival for signals emitted by the different sources are measured by correlating the transmitted and received signals. The distances between the multiple transmitters and a receiver are estimated, and a trilinearization algorithm is used to estimate the position of the buried sensor in 3-D with respect to reference coordinates. The system is tested in a soil tank. The experimental results show that the proposed system is able to estimate the 3-D position of buried sensors with an error of less than $\pm$2.5 cm within a measurement field of size 50 × 50 × 35 cm in X, Y, and Z (width × length × depth). The proposed electronic synchronization approach allows increasing the positioning range of the system by increasing the number of transmitters at the surface. This paves the way for the development of a positioning system for robots operating underground.
Research on Statistical Characteristics of Partial Discharge Ultrasonic Signals in Switchgear

: Switchgear plays a vital role in the power system and is an essential part of ensuring the safe and stable operation of the power system. In this paper, a test platform for partial discharge of switchgear is built on the laboratory site. The creeping discharge model used is the creeping discharge of insulators. At the same time, the ultrasonic signal is collected when partial discharge occurs in the switchgear. According to the data obtained by the platform, using the two characteristic parameters of shape and scale, analyze and discuss the ultrasonic partial discharge of the switchgear based on the threshold value, and give the threshold value suggestion of the switchgear in the actual operating state. The recommended values provide relevant suggestions for power grid operation and maintenance, and have certain guiding significance.
Mouse Models for Unravelling Immunology of Blood Stage Malaria

Malaria comprises a spectrum of disease syndromes and the immune system is a major participant in malarial disease. This is particularly true in relation to the immune responses elicited against blood stages of Plasmodium-parasites that are responsible for the pathogenesis of infection. Mouse models of malaria are commonly used to dissect the immune mechanisms underlying disease. While no single mouse model of Plasmodium infection completely recapitulates all the features of malaria in humans, collectively the existing models are invaluable for defining the events that lead to the immunopathogenesis of malaria. Here we review the different mouse models of Plasmodium infection that are available, and highlight some of the main contributions these models have made with regards to identifying immune mechanisms of parasite control and the immunopathogenesis of malaria.
The Pauli matrices in n dimensions and finest gradings of simple Lie algebras

Procedures are disclosed for producing both core-cladding optical fibers and self-focusing optical fibers from porous germinate and/or silicate glasses obtained after phase separation and removal of the soluble phase. A glass which is separable into at least two phases one of which is soluble, is heated to cause phase separation. The soluble phase is leached out removing undesired impurities. The pores are collapsed and this glass is used to produce cores and/or cladding layers, or self focusing fibers. According to one aspect of the invention, preforms of the porous glass have their interconnected pores stuffed with a dopant. In the production of core-cladding optical fibers, the dopant modifies the index of refraction of the core and/or cladding so that the index of refraction of the core is greater than that of the cladding. The control of this index of refraction can be accomplished by addition of non silicate network formers such as GeO2 to the original melt before phase separation. These network formers will stay in the insoluble phase. In producing self-focusing fibers, the dopant may be non-uniformly deposited in order to produce a radial gradient in the index of refraction, or sodium or potassium ions may be ion exchanged into the glass for a portion of a dopant containing lithium or thallium to produce such an index of refraction gradient.
Comparison of INTEGRA and the Manual Method to Determine the Axis for Intraocular Lens Implantation—A Case Series of 60 Eyes

(1) Background: To compare the results of a new intraoperative contactless device (INTEGRA Optomed, Poland) with the result of a manual method for determining the axis for toric intraocular lens implantation. (2) Material and Methods: This retrospective observational study included 60 eyes of 40 patients (17 men, 23 women) who had toric intraocular lenses implanted. A video recording of each surgery that used the INTEGRA system was made for the analysis. Two researchers then independently assessed the location of the implant axes determined with both digital and manual slit-lamp methods, and compared the results between methods. (3) Results: The implantation axes suggested through the manual and INTEGRA methods were similar. The median axis disparities were 0.0 degrees for both groups. The standard deviation was 0.63 and 0.75 for researcher 1 and 2, respectively. The dominant value was 0.0 in both groups. The INTEGRA axis designation was statistically significantly different from the manual method for researcher 1 (p < 0.05), but it was statistically insignificant for researcher 2 (p = 0.79). (4) Conclusions: The INTEGRA system is a digital ink-free device for image tracking scleral vessels. It was helpful for determining the implantation axis in a precise manner, and the measurements were comparable with those obtained through a manual technique.

Size-Dependent Phonon-Assisted Anti-Stokes Photoluminescence in Nanocrystals of Organometal Perovskites

Anti-Stokes photoluminescence (ASPL), which is an up-conversion phonon-assisted process of the radiative recombination of photoexcited charge carriers, was investigated in methylammonium lead bromide (MALB) perovskite nanocrystals (NCs) with mean sizes that varied from about 6 to 120 nm. The structure properties of the MALB NCs were investigated by means of the scanning and transmission electron microscopy, X-ray diffraction and Raman spectroscopy. ASPL spectra of MALB NCs were measured under near-resonant laser excitation with a photon energy of 2.33 eV and they were compared with the results of the photoluminescence (PL) measurements under non-resonant excitation at 3.06 eV to reveal a contribution of phonon-assisted processes in ASPL. MALB NCs with a mean size of about 6 nm were found to demonstrate the most efficient ASPL, which is explained by an enhanced contribution of the phonon absorption process during the photoexcitation of small NCs. The obtained results can be useful for the application of nanocrystalline organometal perovskites in optoelectronic and all-optical solid-state cooling devices.
Students’ ideas of contributing to sustainable development: a study of how ideas emerge, travel and expand through classroom microblogging and discussions

Abstract This qualitative study investigates how young students expressed, explored and expanded their ideas of how they could contribute to sustainable development. We analyse a trajectory in a Norwegian 8th grade class, focusing on the students’ emerging understanding through microblogging and talk in individual, group and whole class activities. The material analysed are logs from a microblogging tool and transcribed video recordings from two lessons. We examined the trajectory as a whole to understand how the topic was treated, we sorted students’ microblogs thematically, and we used interaction analysis to investigate talk excerpts. The results show that the students initially tended to suggest everyday actions related to reducing consumption, and that through classroom interactions about a challenging idea their understanding broadened. The combination of microblogging activities and discussions facilitated the travelling of ideas between activities and participants, prompted the students to question, elaborate and reason, supported broad participation, and helped students create links between everyday actions and wider sustainability issues.
Machine Learning Tools and Platforms in Clinical Trial Outputs to Support Evidence-Based Health Informatics: A Rapid Review of the Literature

Background: The application of machine learning (ML) tools (MLTs) to support clinical trials outputs in evidence-based health informatics can be an effective, useful, feasible, and acceptable way to advance medical research and provide precision medicine. Methods: In this study, the author used the rapid review approach and snowballing methods. The review was conducted in the following databases: PubMed, Scopus, COCHRANE LIBRARY, clinicaltrials.gov, Semantic Scholar, and the first six pages of Google Scholar from the 10 July–15 August 2022 period. Results: Here, 49 articles met the required criteria and were included in this review. Accordingly, 32 MLTs and platforms were identified in this study that applied the automatic extraction of knowledge from clinical trial outputs. Specifically, the initial use of automated tools resulted in modest to satisfactory time savings compared with the manual management. In addition, the evaluation of performance, functionality, usability, user interface, and system requirements also yielded positive results. Moreover, the evaluation of some tools in terms of acceptance, feasibility, precision, accuracy, efficiency, efficacy, and reliability was also positive. Conclusions: In summary, design based on the application of clinical trial results in ML is a promising approach to apply more reliable solutions. Future studies are needed to propose common standards for the assessment of MLTs and to clinically validate the performance in specific healthcare and technical domains.
