A pedagógusképzés és a szakképzés új összefüggései
Authors: Benedek András , Lőrincz Éva Anna
Published: March 2021

Jelentős fordulóponthoz érkezett a hazai pedagógusképzés átalakítása, mely az általános feladatok mellett sajátos kérdésekre is keresi a válaszokat. E problémakör lényeges eleme a szakképzési rendszer által igényelt és foglalkoztatott pedagógusok képzésének sajátosságai, amelynek történetisége, intézményi sajátosságai a fejlődést jelentősen meghatározó tényezők. A tanulmány ezzel az összetett témakörrel, a kihívásokat és lehetőségeket komplexen mérlegelve foglalkozik a pedagógusképzés általános és a szakképzés sajátos jellemzőinek rendszerezése alapján. A szerzők kísérletet tesznek a képzési folyamat főbb szakaszainak a leírására, továbbá a szakmai pedagógusképzésre jellemző progresszív törekvések szemléltetésére ismertetik a Budapesti Műszaki és Gazdaságtudományi Egyetemen megvalósult szolgáltató és kutatóhálózat kialakítására irányuló projektet.
Pedagógusjelöltek útja az inkluzív iskola felé
Authors: Varga Aranka
Published: March 2021

A felsőoktatás rendszerében elengedhetetlen, hogy a tanár szakos hallgatók megismerkedjenek a különböző társadalmi hátterű, kulturális hovatartozású és egyéni sajátosságokkal rendelkező tanulók címkézésektől mentes nevelésével. Vagyis elsődleges a pedagógusjelöltek számára olyan kompetenciák kialakítása, melyek képessé teszik őket a – heterogén iskolai közegben zajló, valamint a diákok egyediségében rejlő sokszínűséget értékként elismerő, arra pedagógiailag eredményesen reflektáló – minőségi oktatási környezet megszervezésére. Mindezt a tudást összefoglalóan az inkluzív nevelés szemléletének és gyakorlatának nevezzük. Az inklúziót támogató tanári kompetenciák kialakításának folyamata kettős: szükséges hozzá a célzott kurzusok egymásra épülő sora, valamint a felsőoktatást átható inkluzív szemlélet és gyakorlat. A következőkben e két terület bemutatására kerül sor a Pécsi Egyetem vonatkozásában.

iskolák szakmai felügyelete Németországban: Hessen tartomány példája
Authors: Bikics Gabriella
Published: March 2021

A magyar oktatáspolitika egyik legfontosabb új „projektje“ a tanfelügyeleti rendszer reformja. A koncepció már körvonalazódott, jelenleg az első tanfelügyelők képzése folyik. Ezért indokolt a nemzetközi kitekintés, különösen egy olyan országra, amihez politikai, gazdasági és kulturális téren ezer szállal kötődtünk és kötődünk ma is. A szerző bemutatja a német tanfelügyelet történetét, változásait és jelenlegi koncepcióját, különös tekintettel Hessen tartományra. Leírja a tanfelügyeleti látogatások menetét, módszereit, eszközeit és eredményeit. A német példa megismerése sok tanulsággal szolgálhat a magyar tanfelügyeleti rendszer számára.
Iskolaértékelés, szakfelügyelet Hollandiában
Authors: Major Éva
Published: March 2021

A tanulmány célja, hogy bemutassa a Holland Oktatási Felügyelőség (Inspectie van het Onderwijs) szerepét az iskolák és ezen keresztül az oktatás minőségének ellenőrzésében. Az elmúlt húsz év holland oktatáspolitikájában két fontos irányvonal figyelhető meg. Egyrészt egyre nagyobb az igény az oktatáshoz kapcsolódó teljesítményelvárások és sztenderdek meghatározására és érvényesítésére, másrészt az országos szabályozás csökkenésével az oktatási intézmények autonómiája és felelőssége folyamatosan nő saját politikájuk és gyakorlatuk kialakításában. Ezekhez a tendenciákhoz illeszkedik az Oktatási Felügyelőség szerepének változása is, hiszen az intézmény a jelenlegi rendszerben inkább kiegészíti az iskola által alkalmazott minőségellenőrző folyamatokat és mechanizmusokat.

Chronic Fatigue Syndrome
Authors: Sue Graves B. , Kame Sigourney
Published: March 2021

Chronic fatigue syndrome is an enduring disease, characterized by a level of persistent fatigue for 6 months or a longer time period. At this time, the etiology is unknown. The other symptoms individuals effected by chronic fatigue syndrome, may experience are sore throat, headaches, impaired cognition, depression, sleep disturbances, and many others. While the diagnosis of chronic fatigue syndrome can be challenging, the Center for Disease Control (CDC) has a set of guidelines to help characterize the presence of this condition in patients. Chronic fatigue syndrome has far-reaching consequences impacting an individual’s physical and mental wellbeing. The best approach in helping these individuals to still engage in physical activity is through gentle, lowlevel exercise program with the use of patient feedback to individualize the treatment as well as providing guidance and support through support groups and therapy as prescribed by a medical professional.

Propp porno: las fabulosas categorías de la novelística de Silvia C. Carpallo
Authors: Bellomi Paola
Published: March 2021

La novelística porno y erótica sigue, en múltiples aspectos, los recursos propios de las fábulas, según la teorización de V. Propp, para construir su discurso narrativo; se trata de un discurso que muy a menudo intenta reglamentar y normalizar el escándalo que el sexo supone en nuestra sociedad hetero-dominante. La novelística de Silvia C. Carpallo servirá para reflexionar sobre la aportación que el género erótico está haciendo en la defensa o en el derrumbe de la ideología del poder dominante. Mi punto de vista se servirá de la perspectiva queer de la escuela italiana actual y, en particular, de las propuestas de los filósofos Michela Marzano y Lorenzo Bernini, en línea con J. Butler, A. Cavarero y M. Foucault. El propósito es reflexionar sobre las categorías de pensamiento que la literatura erótica española contemporánea está defendiendo y poner al descubierto sus mecanismos de ruptura o de conservación de la norma.

De escritores portátiles y bárbaros: Vila-Matas y Bolaño escribiendo historias de la literatura inventadas
Authors: González Ángel Sara
Published: March 2021

En este artículo he tratado de poner en relación dos novelas: Historia abreviada de la literatura portátil (1985), de Enrique Vila-Matas, y Estrella distante (1996), de Roberto Bolaño. Para ello se ha tomado como eje de comparación las historias de la literatura inventadas que aparecen en ambas obras y los mecanismos utilizados en su construcción.

Mixed vs Stable Anti-Yetter-Drinfeld Contramodules
Authors:   University of Windsor, Canada, Shapiro Ilya
Published: March 2021

We examine the cyclic homology of the monoidal category of modules over a finite dimensional Hopf algebra, motivated by the need to demonstrate that there is a difference between the recently introduced mixed anti-Yetter-Drinfeld contramodules and the usual stable anti-Yetter-Drinfeld contramodules. Namely, we show that Sweedler's Hopf algebra provides an example where mixed complexes in the category of stable anti-Yetter-Drinfeld contramodules (previously studied) are not equivalent, as differential graded categories to the category of mixed anti-Yetter-Drinfeld contramodules (recently introduced).

Eridanus II (Eri II) is an ultrafaint dwarf (UFD) galaxy (M

V
= −7.1) located at a distance close to the Milky Way virial radius. Early shallow color–magnitude diagrams (CMDs) indicated that it possibly hosted an intermediate-age or even young stellar population, which is unusual for a galaxy of this mass. In this paper, we present new Hubble Space Telescope/Advanced Camera for Surveys CMDs reaching the oldest main-sequence turnoff with excellent photometric precision and derive a precise star formation history (SFH) for this galaxy through CMD fitting. This SFH shows that the bulk of the stellar mass in Eri II formed in an extremely short star formation burst at the earliest possible time. The derived star formation rate profile has a width at half maximum of 500 Myr and reaches a value compatible with null star formation 13 Gyr ago. However, tests with mock stellar populations and with the CMD of the globular cluster M92 indicate that the star formation period could be shorter than 100 Myr. From the quantitative determination of the amount of mass turned into stars in this early star formation burst ( ∼2 × 105
M
⊙) we infer the number of supernova (SN) events and the corresponding energy injected into the interstellar medium. For reasonable estimates of the Eri II virial mass and values of the coupling efficiency of the SN energy, we conclude that Eri II could be quenched by SN feedback alone, thus casting doubts on the need to invoke cosmic reionization as the preferred explanation for the early quenching of old UFD galaxies.

Mini-EUSO is a telescope observing the Earth in the ultraviolet band from the International Space Station. It is a part of the JEM-EUSO program, paving the way to future larger missions, such as K-EUSO and POEMMA, devoted primarily to the observation of ultrahigh-energy cosmic rays from space. Mini-EUSO is capable of observing extensive air showers generated by ultrahigh-energy cosmic rays with an energy above 1021 eV and to detect artificial showers generated with lasers from the ground. Other main scientific objectives of the mission are the search for nuclearites and strange quark matter, the study of atmospheric phenomena such as transient luminous events, meteors, and meteoroids, the observation of sea bioluminescence and of artificial satellites and man-made space debris. Mini-EUSO will map the nighttime Earth in the UV range (290–430 nm), with a spatial resolution of about 6.3 km and a temporal resolution of 2.5 μs, through a nadir-facing UV-transparent window in the Russian Zvezda module. The instrument, launched on 2019 August 22, from the Baikonur Cosmodrome, is based on an optical system employing two Fresnel lenses and a focal surface composed of 36 multianode photomultiplier tubes, 64 channels each, for a total of 2304 channels with single-photon counting sensitivity and an overall field of view of 44°. Mini-EUSO also contains two ancillary cameras to complement measurements in the near-infrared and visible ranges. In this paper, we describe the detector and present the various phenomena observed in the first months of operations.
A CO Survey of SpARCS Star-forming Brightest Cluster Galaxies: Evidence for Uniformity in BCG Molecular Gas Processing across Cosmic Time

Published: March 2021

We present ALMA CO (2-1) detections of 24 star-forming brightest cluster galaxies (BCGs) over 0.2 < z < 1.2, constituting the largest and most distant sample of molecular gas measurements in BCGs to date. The BCGs are selected from the Spitzer Adaptation of the Red-Sequence Cluster Survey (SpARCS) to be IR-bright and therefore star-forming. We find that molecular gas is common in star-forming BCGs, detecting CO at a detection rate of 80% in our target sample of 30 objects. We additionally provide measurements of the star formation rate and stellar mass, calculated from existing MIPS 24 μm and IRAC 3.6 μm fluxes, respectively. We find these galaxies have molecular gas masses of 0.7–11.0 × 1010
M
⊙, comparable to other BCGs in this redshift range, and specific star formation rates that trace the main sequence of Elbaz et al. We compare our BCGs to those of the lower-redshift, cooling-flow BCG sample assembled by Edge and find that at z ≲ 0.6 the two samples show very similar correlations between their gas masses and specific SFRs. We suggest that, in this redshift regime, the ∼10% of BCGs that are star-forming process accreted molecular gas into stars through means that are agnostic to both their redshift and their cluster mass.

The stability and convergence of the Fourier pseudo-spectral method are analyzed for the three dimensional incompressible Navier-Stokes equation, coupled with a variety of time-stepping methods, of up to fourth order temporal accuracy. An aliasing error control technique is applied in the error estimate for the nonlinear convection term, while an a-priori assumption for the numerical solution at the previous time steps will also play an important role in the analysis. In addition, a few multi-step temporal discretization is applied to achieve higher order temporal accuracy, while the numerical stability is preserved. These semi-implicit numerical schemes use a combination of explicit Adams-Bashforth extrapolation for the nonlinear convection term, as well as the pressure gradient term, and implicit Adams-Moulton interpolation for the viscous diffusion term, up to the fourth order accuracy in time. Optimal rate convergence analysis and error estimates are established in details. It is proved that, the Fourier pseudo-spectral method coupled with the carefully designed time-discretization is stable provided only that the time-step and spatial grid-size are bounded by two constants over a finite time. Some numerical results are also presented to verify the established convergence rates of the proposed schemes.

The paper considers the problem of handling short sets of medical data. Effectively solving this problem will provide the ability to solve numerous classification and regression tasks in case of limited data in health decision support systems. Many similar tasks arise in various fields of medicine. The authors improved the regression method of data analysis based on artificial neural networks by introducing additional elements into the formula for calculating the output signal of the existing RBF-based input-doubling method. This improvement provides averaging of the result, which is typical for ensemble methods, and allows compensating for the errors of different signs of the predicted values. These two advantages make it possible to significantly increase the accuracy of the methods of this class. It should be noted that the duration of the training algorithm of the advanced method remains the same as for existing method. Experimental modeling was performed using a real short medical data. The regression task in rheumatology was solved based on only 77 observations. The optimal parameters of the method, which provide the highest prediction accuracy based on MAE and RMSE, were selected experimentally. A comparison of its efficiency with other methods of this class has been performed. The highest accuracy of the proposed RBF-based additive input-doubling method among the considered ones is established. The method can be modified by using other nonlinear artificial intelligence tools to implement its training and application algorithms and such methods can be applied in various fields of medicine.

Although fly ash is commonly used as an additive to cement, large amounts of this material are disposed in landfills. To mitigate, it would be interesting to develop new products in which fly ash can be easily used and required in large quantities. In this work, fly ash is added to manufacture eco-friendly materials with acceptable acoustic and non-acoustic properties and a low cost. We built a barrier composed of fly ash (60 wt.%), type II Portland cement (25 wt.%), vermiculite (14.5 wt.%) and polypropylene fibers (0.5 wt.%). The barrier complied with the mechanical requirements of European standards. The sound absorption coefficient and the airborne sound insulation were determined in a reverberation room, and the barrier was classified as A2 and B3. No leaching problems were observed.

Published: March 2021

In this study, different proportions of gypsum composite reinforced with recycled cellulose fibers and expanded polystyrene were produced to study the properties of thermal conductivity, density, and flexural strength to be used as sealing plates to improve the thermal comfort of buildings. Different gypsum matrix composites were produced with varied proportions of cellulose fiber and expanded polystyrene, to analyze the influence of residues on the properties of the material. The thermal conductivity obtained for composites with greater amounts of expanded polystyrene was 0.18 W/mK, a 48% reduction in relation to plasterboard, improving thermal performance. The flexural strength was also analyzed, which met the minimum strength requirement for use as gypsum composites, however, it is not enough to be used in places that require mechanical resistance, thus it is indicated for sealing plates applications, improving the thermal performance of places where only plasterboard is used.

O professor é elemento chave no aprimoramento dos comportamentos dos alunos, servindo como modelo para a expressão de reações adequadas ao ambiente. Portanto, um professor com repertório de Habilidades Sociais Educativas (HSE) desenvolvido têm mais chances de obter êxito na relação professor-aluno e menores índices de adoecimento emocional. O estudo objetivou avaliar e comparar o repertório de HSE com os níveis depressivos, de ansiedade e estresse em professores de ensino fundamental, correlacionando ao perfil sociodemográfico dos participantes. Foram utilizados o Inventário de Habilidades Sociais Educativas-Professores e a Depression Anxiety Stress Scale. Trata-se de um estudo quantitativo transversal, correlacional e comparativo, embasado na perspectiva da teoria comportamental. Participaram 109 professores de escolas públicas e privadas do norte do Estado do Rio Grande do Sul, sendo 96,3% mulheres (M= 42,06 anos; DP=9,38). Os achados apontaram escores mais elevados de ansiedade, estresse e depressão nos professores de escolas públicas, com um repertório mais elaborado de HSE, enquanto nos docentes de escolas particulares encontrou-se correlação positiva entre HSE e sintomas depressivos e de ansiedade. Conclui-se que os professores podem se beneficiar de programas que estimulem interações sociais mais habilidosas, por meio das quais poderão desenvolver práticas educativas mais positivas e mais qualidade de vida.

A alienação parental refere-se a um conjunto de comportamentos emitidos, consciente ou inconscientemente, por um dos genitores, com vistas a impedir o relacionamento da criança com o outro progenitor. O objetivo deste artigo foi analisar, com base em uma revisão sistemática da literatura, a qualidade dos instrumentos psicológicos adotados em pesquisas sobre alienação parental. Para isso, consultou-se as bases de dados Pubmed, PsycoINFO, Scielo, Scopus e Web of Science. Nesta revisão, incluíram-se artigos empíricos publicados entre os anos de 1986 e 2019. A seleção dos artigos foi realizada por duas juízas independentes. Foram recuperados 184 artigos. Desses, 17 foram analisados. Quanto às propriedades psicométricas, todos os estudos apresentaram evidências de precisão satisfatórias. Contudo, somente seis instrumentos apresentaram evidências de validade baseadas na estrutura interna ou em evidências de validade relacionadas com variáveis externas. Uma vez que a alienação parental é um fenômeno complexo e, a maioria dos instrumentos identificados não apresentou informações suficientes para a sua utilização no contexto profissional, é importante que se invista em iniciativas que qualifiquem os instrumentos nessa área.

HYBRID CLASSIFICATION STRATEGY OF EMG SIGNALS FOR ROBOTIC HAND CONTROL
Authors: Sbargoud Fazia , Djeha Mohamed , Guiatni Mohamed , Ababou Noureddine
Published: March 2021

Among the different bio-signals modalities, Electromyographic signal (EMG) has been one of the frequently used signals in the bio-robotics applications field. This is due to the fact that the EMG reflects directly the muscle activity of the user following the human motion intention. Consequently, the decoding of this intention is an essential task for controlling devices such as prosthetic hands and exoskeletons, based on EMG signals. This paper deals with the processing of EMG signals of the forearm muscles, in order to control two degrees of freedom (2 DoFs) robotic hand. The main contribution of this paper is the proposal of a hybrid approach that combines a pattern and a non-pattern recognition-based strategy. The proposed approach aims to take advantage of both strategies and overcome their shortcomings leading to a better analysis of the user movement intention. The EMG recorded signals are processed for feature extraction based on a Wavelet Packet Decomposition (WPD) method and classification using an Artificial Neural Network (ANN). Furthermore, we investigate the effect of the various parameters such as the applied force level, the number of the EMG channels and the window length of the EMG signal. The proposed approach is validated experimentally under realistic conditions. Very interesting results have been obtained for user intention decoding.

Authors: Mahenge Michael Pendo John , Msungu Andrew Charles
Published: March 2021

The recent development of ubiquitous technologies such as mobile computing facilities in developing countries promises a cost-effective approach for learning in higher learning institutions (HLIs). For instance, in Tanzania, new technologies in HLIs are being blended through eLearning and m-learning. However, HLIs are facing challenges in the delivery of eLearning contents due to the distributed nature of learning environments, the advancement of a large amount of data, shortage in ICT resources, and bandwidth. This study presents the state-of-the-art challenges and opportunities on eLearning in Tanzania. The survey results show that above 75% of students own multiple mobile devices that can support access to M-learning. Then, a cost-effective strategy for content delivery supported by mobile edge computing and cloud computing is proposed. Moreover, it is recommended that HLIs in developing countries should enact ICT policy that integrates issues associated with how to effectively utilize the emerging ubiquitous technologies applicable in their learning environments.

Published: March 2021

The human ability to reason and comprehend the world requires the coherent activity of billions of neurons. At the same time, the biological existence is rooted in seamless interactions between thousands of genes and metabolites within the cells. These are complex systems which capture the fact that it is challenging to derive their collective behavior from the knowledge of the system's components. Given the critical role, complex systems play in daily life, their understanding, mathematical description, prediction, and eventually, control is one of the significant intellectual and scientific challenges of the 21st century. The advent of network science is a clear demonstration that science can live up to this challenge.
