Architectural and Comparative Material Study of Brick and Mortar of Ahom Terracotta Monuments, Assam, India
Authors: - Saurav Khuttiya Deori , - Sukanya Sharma , - Deep Bora
Published: March 2023

The Ghanasyam house of Sivasagar district and Namath Kali Mandir(Temple) of Nilachal hills, Guwahati, Assam, are among the most unique and detailed ornamented brick architecture monuments built during the reign of the Ahom dynasty in India. Although Namath kali mandir has retained only a few portions of its original architecture due to natural causes and vegetation, the remains still display detailed ornamentation. According to historians and scholars, both monuments follow similar architectural styles irrespective of geographical differences. This paper compares and analyses the architectural structure of both monuments. It studies the elemental compositions of bricks and mortar of each monument and compares the composition and structural pattern using Energy Dispersive X-Ray Analysis (EDX), Fourier transform infrared (FT-IR), and Powder X-ray diffraction (PXRD). The results provide similarities in elemental compositions and structural patterns of the Bricks and Mortars of both monuments.
An Examination on the Consistency of Forensic Information in Criminal Courts in India
Authors: - Deepali S Bhalshankar
Published: March 2023

The study aims to examine how forensic science and law interact, as well as to evaluate the role and significance of forensic evidence in the criminal justice system. The research will emphasise the many uses of incidental evidence. The primary method used to collect the data for this project was a prospective study of official record data that followed criminal cases in two jurisdictions (Los Angeles County, Indianapolis, Evansville, Fort Wayne, and South Bend) from the time police incident reports were filed until the case was finally resolved in court. Municipal, county, and state crime laboratory services are represented by the sites selected. Data for the study were gathered using a random sample of the population of recorded crime occurrences for the year 2021, stratified by crime category and jurisdiction. We solely focused on the violent assault crime episodes out of 4,205 overall instances, which included 859 violent assaults, 1,263 burglaries, 400 homicides, 602 rapes, and 1,083 robberies. An arrest was made in 49% of assault incidents. Bivariate analyses of instances with and without evidence from the crime scene revealed statistically significant increased rates of arrest, prosecutor referral, charge, and conviction in cases with forensic evidence. Using multivariate analysis, it was shown that acquiring physical evidence was a statistically significant predictor of arrest. Despite the increased focus given to forensic evidence in recent years, little empirical information is available about the types of evidence that are often acquired as well as how frequently they are submitted to and analysed in forensic crime laboratories. Even little research has been done to clarify how such evidence affects the criminal justice process.

Authors: Keller Stefan D.
Published: March 2023

In diesem Beitrag wird aufgezeigt, was elektronische Portfolios (E-Portfolios) als Lerninstrumente auszeichnet und wie damit pädagogische Herausforderungen in der Lehrerinnen- und Lehrerbildung sinnvoll angegangen werden können. Zentrale Ziele bestehen darin, erstens Verbindungen zwischen persönlichen Unterrichtsvorstellungen und dem fachdidaktischen Wissen der Studierenden herzustellen, zweitens komplexe Handlungskompetenzen zu dokumentieren und zu überprüfen und drittens verschiedene Ausbildungsteile kongruent miteinander zu vernetzen (z.B. Fachdidaktik und berufspraktische Ausbildung). Anhand konkreter Beispiele wird aufgezeigt, wie diese Ziele mithilfe von E-Portfolios in der Praxis umgesetzt werden können und welche Herausforderungen dabei zu bewältigen sind.
Kompetenzorientierung als Leitbegriff der Didaktik
Authors: Reusser Kurt
Published: March 2023

Im Beitrag wird der Begriff der Kompetenzorientierung als didaktischer Leitbegriff aus einem wissenspädagogischen Blickwinkel beleuchtet. Auch unter der Leitidee der Kompetenzorientierung bleibt die kulturelle Dimension von Wissen und fachlicher Bildung zentral. Weder wird der Wissenskern von Bildung abgewertet, noch die Rolle von Lehrpersonen und Instruktion entwertet. Sodann wird der Frage nachgegangen, was unter kompetenzorientiertem Unterricht als (fach)didaktischer Aufgabe zu verstehen ist und welches dabei die Rolle von Lehrpersonen als Diagnostikerinnen und Diagnostikern von Lernaufgaben und als Gestalterinnen und Gestaltern von Lernumgebungen ist.

Published: March 2023

An der Pädagogischen Hochschule der Fachhochschule Nordwestschweiz (PH FHNW) wurde ein Video-Portfolio zur summativen Überprüfung berufspraktischer Kompetenzen am Ende der Lehrpersonenausbildung entwickelt: Studierende planen, dokumentieren und analysieren gefilmte Lektionen eigenen Unterrichts und reflektieren ihre Lehrkompetenzen. Geschulte Fachpersonen beurteilen die Arbeiten anhand eines Rasters. Das Video-Portfolio erweist sich als stärker differenzierend und selektiver im Vergleich zur vorherigen Live-Beobachtung. Reliabilitäts- und Validitätsstudien sowie Weiterentwicklungen sind initiiert.
Blinder Fleck bei der TEDS-M-Messung der Überzeugungen zum Lehren und Lernen
Authors: Aeschbacher Urs , Wagner Daniel
Published: March 2023

In den Items des TEDS-M-Erhebungsinstruments zu didaktischen Überzeugungen der angehenden Lehrkräfte wird einerseits sogenannt konstruktionsorientierter Unterricht mit verstehendem Lernen und andererseits sogenannt transmissionsorientierter Unterricht mit oberflächlichem Lernen assoziiert. Von daher erstaunt der empirische Befund nicht, dass die Lehrpersonenausbildung zu einer Verstärkung der «Konstruktionsorientierung» und zu einer deutlichen Ablehnung der «Transmissionsorientierung» führe. Der vorliegende Beitrag argumentiert kritisch, dass dieses Erhebungsinstrument einen blinden Fleck bezüglich eines verständnisorientierten darbietenden Unterrichts aufweist.

Zum pädagogischen Können der Lehrerinnen und Lehrer in der Migrationsgesellschaft – Versuch der Konturierung einer kritisch-reflexiven Professionalität
Authors: Ivanova-Chessex Oxana , Fankhauser Marco , Wenger Marco
Published: March 2023

Obwohl Migration eine wesentliche historische Konstante des menschlichen Daseins darstellt, fühlen sich Schulen und pädagogisch Tätige diesbezüglich mit "neuen" Fragen und Anforderungen konfrontiert. Im vorliegenden Beitrag wird vor dem Hintergrund der gängigen pädagogischen Antworten auf Migrations- und Fluchtverhältnisse eine mindestens zu erwägende Perspektive vorgestellt, die unter dem Stichwort "kritisch-reflexive Professionalität" diskutiert wird. Dabei wird auf das poststrukturalistisch informierte Subjektverständnis und einen damit einhergehenden dekonstruktiven Blick auf die Professionalität und die Professionalisierung Bezug genommen sowie auf die Überlegungen der Migrationspädagogik und der postkolonialen Theorie rekurriert.
Digitale Heterogenität von Lehrpersonen – Herausforderung oder Chance für die ICT-Integration in Schulen?
Authors: Prasse Doreen , Döbeli Honegger Beat , Petko Dominik
Published: March 2023

Lehrpersonen sind bezüglich ihrer Einstellungen und Kompetenzen zur Nutzung digitaler Medien sehr heterogen, was wiederum unterschiedliche Integrationsstrategien und Nutzungsmuster dieser Medien zur Folge hat. Für Schulen ergibt sich hiermit die Herausforderung, einerseits die bestehende Heterogenität zu reduzieren, um Verbindlichkeit und Chancengerechtigkeit für alle Schülerinnen und Schüler zu wahren, und andererseits diese Vielfalt als Chance zu nutzen. Der vorliegende Beitrag gibt einen Überblick über verschiedene Dimensionen dieser Heterogenität und analysiert Bedingungen für deren Entstehen. Abschließend werden – unter einem „Diversity“-Blickwinkel – mögliche Chancen diskutiert und Schlussfolgerungen für Schulen formuliert.

Arbeiten in multiprofessionellen Teams – eine Herausforderung, die bereits im Lehramtsstudium beginnt
Authors: Preis Nina , Wissinger Jochen
Published: March 2023

Ganztagsschulen werden in Deutschland zunehmend zur Selbstverständlichkeit. Dies bedeutet gleichzeitig eine veränderte Rolle der Lehrkräfte: So ist es mehr denn je erforderlich, dass diese mit anderen Professionen zusammenarbeiten. Geleitet von der Idee, dass die Entwicklung von Multiprofessionalität bereits im Studium beginnen muss, wird an der Justus-Liebig-Universität Gießen das Modul „Arbeiten in multiprofessionellen Teams“ entwickelt. Ziel ist es, Lehramtsstudierende für die Potenziale von Kooperationen mit außerunterrichtlichen pädagogischen Fachkräften zu sensibilisieren und sie in der Wahrnehmung ihrer eigenen Professionalität sowie in der Wertschätzung anderer Professionen zu stärken.

Annotationstools für die kollaborative Arbeit mit Unterrichtsvideos: Eine Übersicht
Authors: Dähling Christoph , Standop Jutta
Published: March 2023

In der Lehrerinnen- und Lehrerbildung hat der Einsatz videobasierter Methoden Tradition und gewinnt weiter an Zuspruch. Den Vorteilen dieser Form stehen jedoch auch Nachteile gegenüber: Die Flüchtigkeit der Videoform erschwert eine gehaltvolle gemeinsame Auseinandersetzung mit den Inhalten, besonders in asynchronen Online-Settings. Tools zur kollaborativen Annotation von Videos können hier einen Ausweg bieten. Der Markt hierfür ist jedoch disparat und unübersichtlich, sodass es schwierig ist, die richtige Anwendung zu finden. Dabei will der vorliegende Beitrag helfen, indem die maßgeblichen Anwendungen identifiziert und mit ihren Vor- und Nachteilen aufgeführt werden.

Application of Machine Learning Methods for Data Analytics in Social Sciences
Authors: Oreski Dijana
Published: March 2023

This article addresses the challenges in the application of artificial intelligence methods such as machine learning, computational intelligence and/or soft computing methods in social sciences. The literature review is performed in order to give a review of different approaches and methods that have been applied so far. The most used method in social sciences and management is the SWOT method, for the identification of strengths, weaknesses, opportunities, and threats when making strategic decisions. Two fundamental characteristics of previous approaches are the development of numerical models of utility functions and the possibility of upgrading these models by formalizing the intuition of strategic decision-makers. There are several shortcomings of the existing approaches. The application of computational intelligence and machine learning methods in social sciences is identified as one of the most challenging and promising areas, which could overcome identified shortcomings. The principles of one popular machine learning method, the decision tree, are explained and a demonstration is performed on the case study of churn prediction. Benchmarking data set from the publicly available repository is used to demonstrate the suggested approach Evaluation results measured through model accuracy and reliability gave promising results for further analysis. A developed predictive model could serve as a standalone tool or as support for decision-making in social sciences.
Real Time Discrete Optimized Adaptive Control for Ionic Polymer Metal Composites
Authors: Tsiakmakis Kyriakos , Delimaras Vasileios , Hatzopoulos Argyrios T. , Papadopoulou Maria S.
Published: March 2023

This paper describes a proposed method for optimizing the parameters of a Model Reference Adaptive Control (MRAC) system. The MRAC system uses a reference model to control a plant with unknown dynamics and continuously updates its parameters to improve control accuracy. The system requires an adjustment of parameter γ, which participates in the feedback of the system but cannot be adjusted in real time through trial and error. The proposed method uses optimization techniques to adjust the γ parameters in real time, specifically at the start of the control process, when the maximum deviation of the plant from the reference model is observed. The optimization technique varies the parameters and seeks the best solution to quickly reduce the error. Once the optimal solution is found, the optimization is turned off, allowing the MRAC to continue efficiently reducing the error. In the case of sudden changes in the error due to endogenous or exogenous factors, optimization is activated again to redefine the γ parameters. The magnitude of the change depends on the rate of error changes. The response of the IPMC was measured and compared against a reference signal using three different control techniques MRAC, Model Reference Adaptive Control (MRAC), MRAC-Taguchi, and MRAC-Taguchi-DCT, and the results show that the last penalizes frequencies beyond the fundamental frequency through the cost function, resulting in negligible harmonic distortion.

Published: March 2023

This study aims to examine the relationship between individual value and knowledge creation in human capital.The effect of individual value on each element of knowledge creation – socialization, externalization, combination and internalization – is tested in this study. The study also tested the effect of each component of knowledge creation with human capital. Data were collected using an online questionnaire. A total of 286 questionnaires were sent to managers of medium-sized companies in the province of Bali, Indonesia. Of the 196 questionnaires that were sent, returned and filled out completely, 158 had responses that were utilizable, showing a usable response rate of 80.61%. Data analysis was carried out using variance-based structural equation modelling with a partial least squares approach (SEM-PLS) with WarpsPLS 7.0. The results of the study found a significant positive effect of individual value on each element of knowledge creation: with socialization, with externalization, with combination and with internalization. This study also found that each component of knowledge creation has a significant positive effect on human capital: socialization, externalization, combination and internalization, respectively. This study shows that the value that is believed by individuals based on knowledge can be a strong factor of competitiveness for future of human capital.

Published: March 2023

We report evidence of comet-like activity on asteroid 2009 DQ118, a quasi-Hilda object near the 3:2 interior mean-motion resonance with Jupiter. This discovery was made by volunteers as part of the Active Asteroids Citizen Science project, a NASA Partner hosted on the Zooniverse platform. Follow-up archival searches yielded over 20 images of 2009 DQ118 exhibiting a comet-like tail on UT 2016 March 8 and 9 acquired with the Dark Energy Camera on the Blanco 4 m telescope at the Cerro Tololo Inter-American Observatory, Chile. These images were taken when 2009 DQ118 was near its 2016 perihelion passage. 2009 DQ118 will next reach perihelion on UT 2023 April 22; hence, the next several months are an excellent time to observe 2009 DQ118 to search for a second epoch of activity for this object.
No MSP Counterparts Detected in GBT Searches of Spider Candidates 4FGL J0935.3+0901, 4FGL J1627.7+3219, and 4FGL J2212.4+0708

Published: March 2023

We performed radio searches for the “spider” millisecond pulsar (MSP) candidates 4FGL J0935.3+0901, 4FGL J1627.7+3219, and 4FGL J2212.4+0708 using the Green Bank Telescope in an attempt to detect the proposed radio counterpart of the multi-wavelength variability seen in each system. We observed using the VEGAS spectrometer, centered predominantly at 2165 MHz; however, we were also granted observations at 820 MHz for 4FGL J1627.7+3219. We performed acceleration searches on each data set using PRESTO as well as additional jerk searches of select observations. We see no evidence of a radio counterpart in any of the observations for each of the three systems at this time. Additional observations, perhaps at different orbital phases (e.g., inferior conjunction), may yield detections of an MSP in the future. Therefore, we urge continued monitoring of these systems to fully characterize the radio nature, however faint or variable, of each system.
The Behavior of BpSi Stars in the Far UV—Paper I: HD 22920
Authors: Monier Richard
Published: March 2023

The analysis of five spectra of the Bp Si star HD 22920 recorded by the SWP camera on board the International Ultraviolet Explorer reveals variations of the far-ultraviolet flux of this star throughout its recently derived rotation period of 3.947 days. Spectra separated by half of the rotation period show variations of the FUV flux shortwards of 1700 Å. The Si ii autoionization lines in the region 1350 to 1460 Å clearly vary in phase with the Si ii doublet near 1530 Å. The FUV variations are caused by variations of the FUV Si ii continuous and line opacity as spots of overabundant silicon come into the line of sight while the star rotates.

Stellar spectra contain a large amount of information about the conditions in stellar atmospheres. However, extracting this information is challenging and demands comprehensive numerical modeling. Here, we present stellar spectra synthesized using the recently developed state-of-the-art MPS-ATLAS code on a fine grid of stellar fundamental parameters. These calculations have been extensively validated against solar and stellar observations and can be used for various astrophysical applications. The spectra are available at the Max Planck Digital Library (https://doi.org/10.17617/3.NJ56TR) and have been also incorporated into the ExoTiC-LD python package (https://github.com/Exo-TiC/ExoTiC-LD/ which returns stellar limb darkening coefficients used for the software package Exoplanet Timeseries Characterisation (ExoTic).

Published: March 2023

Established in 1837, the Trivandrum observatory has been working over the past 185 yr as an institution catering to the scientific and academic community. After a major renovation recently, the arrival of the comet C/2022 E3 (ZTF) has provided an opportunity for the Trivandrum observatory to explore its capability in astronomy. The sky remained clear from February 13th onwards for 5 days, providing a much awaited window for tracking of the path of the comet. An apparent change in the coma is visualized in the images which could be associated with the increase in the radial distance from the Earth and also due to the increase in distance from the Sun.

The use of sentinel woody plants in experimental plantings, Botanical Gardens and Arboreta has been experimentally validated as a tool for identifying possible unknown future threats prior to their introduction into new countries. Sentinel Plantings were recently established in Italy, France, Switzerland, China and South Africa, using a common experimental design. The plantings included various tree and shrub species of broadleaves and conifers. Two planting types were established, each with different objectives. In-patria plantings using native plants aim to estimate, in absence of any phytosanitary treatments, the associations and infestation rates of native insects susceptible to be exported to other countries with that particular commodity. Ex-patria plantings using non-native plants are relevant to identify native insect species capable of switching to the non-native plant that would otherwise be impossible to predict prior to its introduction. In the frame of the EU project HOMED, we have implemented this concept, widening the use of this tool simultaneously to many different countries and continents
First record and description of three new species in the land snail genus Diplommatina Benson, 1849 (Caenogastropoda, Diplommatinidae) from Satun Province, Thailand
Authors: Boonmachai Tuangthong , Bergey Elizabeth A. , Nantarat Nattawadee
Published: March 2023

The micro land snail genusDiplommatina(family Diplommatinidae) is widely distributed in Southeast Asia and includes many endemic species. Three new species ofDiplommatinaare described from Satun Province in southern Thailand.Diplommatina bulonensissp. nov.,D. laemsonensissp. nov.andD. prakaiphetensissp. nov.are distinguished from other species in the genus by their shell size and shape, the number of radial ribs on the penultimate whorl, the number of whorls, and features of the peristome. The agreement between phylogenetic tree based on analyses of COI and 16S sequences and comparative morphology support the delineation of these new species which, when compared to related species, belong to well-differentiated clades. The K2P distance between any of the three new species and otherDiplommatinaspecies included in the molecular phylogenetic analysis was at least 5.5% in COI and 3.9% in 16S. Two of the three new species (D. prakaiphetensissp. nov.andD. bulonensissp. nov.) are apparently endemic to Prakaiphet Hill and Bulon Pai Island, respectively. Additionally, we documented a new regional record forD. naiyanetriin Satun Province. These new species and records contribute to the knowledge of Thailand’s land snail biodiversity and highlight the need of conservation protections for regional karst habitats.
Applying Principles of a Fair and Just Culture to a Student Scenario
Authors: Barnsteiner Jane , Disch Joanne , Johnson Michelle , Spector Nancy
Published: March 2023

Background:

This article reviews national efforts toward promoting fair and just cultures in schools of nursing. A real-life vignette in which a nursing student made a medication error is presented, and the nursing program contacted the nursing regulatory body for advice on how to handle the situation.

Method:

A framework was used to analyze the causes of the error. Commentary is offered regarding how applying the principles of a fair and just culture could improve student performance and advance the school's culture to reflect one that was fair and just.

Results:

A fair and just culture requires a commitment of all leaders and faculty within a school of nursing. Administrators and faculty must recognize that errors are part of the learning process, that errors can be minimized but not eliminated, and that learning can occur from each incident to prevent similar occurrences in the future.

Conclusion:

Academic leaders must engage faculty, staff, and students in a dialogue about the principles of a fair and just culture to develop a tailored plan of action.

Existence, uniqueness, and convergence rates for gradient flows in the training of artificial neural networks with ReLU activation
Authors: Eberle Simon , Jentzen Arnulf , Riekert Adrian , Weiss Georg S.
Published: March 2023

The training of artificial neural networks (ANNs) with rectified linear unit (ReLU) activation via gradient descent (GD) type optimization schemes is nowadays a common industrially relevant procedure. GD type optimization schemes can be regarded as temporal discretization methods for the gradient flow (GF) differential equations associated to the considered optimization problem and, in view of this, it seems to be a natural direction of research to first aim to develop a mathematical convergence theory for time-continuous GF differential equations and, thereafter, to aim to extend such a time-continuous convergence theory to implementable time-discrete GD type optimization methods. In this article we establish two basic results for GF differential equations in the training of fully-connected feedforward ANNs with one hidden layer and ReLU activation. In the first main result of this article we establish in the training of such ANNs under the assumption that the probability distribution of the input data of the considered supervised learning problem is absolutely continuous with a bounded density function that every GF differential equation admits for every initial value a solution which is also unique among a suitable class of solutions. In the second main result of this article we prove in the training of such ANNs under the assumption that the target function and the density function of the probability distribution of the input data are piecewise polynomial that every non-divergent GF trajectory converges with an appropriate rate of convergence to a critical point and that the risk of the non-divergent GF trajectory converges with rate 1 to the risk of the critical point. We establish this result by proving that the considered risk function is semialgebraic and, consequently, satisfies the Kurdyka-Łojasiewicz inequality, which allows us to show convergence of every non-divergent GF trajectory.

Published: March 2023

In recent years, sentiment analysis (SA) has raised the interest of researchers in several domains, including higher education. It can be applied to measure the quality of the services supplied by the higher education institution and construct a university ranking mechanism from social media like Twitter. Hence, this study presents a novel system for Twitter sentiment prediction on Moroccan public universities in real-time. It consists of two phases: offline sentiment analysis phase and real-time prediction phase. In the offline phase, the collected French tweets about twelve Moroccan universities were classified according to their sentiment into ‘positive’, ‘negative’, or ‘neutral’ using six machine learning algorithms (random forest, multinomial Naive Bayes classifier, logistic regression, decision tree, linear support vector classifier, and extreme gradient boosting) with the term frequency-inverse document frequency (TF-IDF) and count vectorizer feature extraction techniques. The results reveal that random forest classifier coupled with TF-IDF has obtained the best test accuracy of 90%. This model was then applied on real-time tweets. The real-time prediction pipeline comprises Twitter streaming API for data collection, Apache Kafka for data ingestion, Apache Spark for real-time sentiment analysis, Elasticsearch for real-time data exploration, and Kibana for data visualization. The obtained results can be used by the Ministry of higher education, scientific research and innovation of Morocco for decision-making process.

E-learning platforms are essential tools used widely for teaching and learning English, especially since the COVID-19 pandemic. They are also used to communicate and interact with students, assess progress, evaluate assignments, and provide feedback. However, teachers of English face potential barriers when they use such platforms. This study examines the use of e-learning platforms in teaching English as a foreign language in Jordan. The study employed a quantitative research method. The findings revealed that using e-learning platforms for educational purposes is beneficial regarding accessibility when attending courses. E-learning enabled the students to practise more and to be more engaged in the learning process, which improved their language skills. Effective e-learning platform strategies significantly broaden students' perceptions and increase the opportunity to exchange information with their classmates. Nonetheless, several impediments may hinder the application of e-learning platforms, including teacher-related, technical, and technological factors. The study recommends that teachers use interactive methods, including images, sounds, videos, and multimedia, to engage learners with various needs and abilities. The study also suggests building codified standards when designing e-learning to develop students' skills at all levels and training teachers on using modern technological strategies in e-learning.

Abstract—The new “Internet+” teaching mode during the COVID-19 pandemic has guaranteed the smooth learning progress of university students in China. High-efficiency reconstruction of time and space for knowledge teaching and internalization based on informationalized teaching mean is an important approach to online learning. A flipped classroom is a teaching mode that is formed through bottom-up exploration. Combined with teaching practical situations, the flipped classroom realizes the transformation from the teacher-centered mode to the student-oriented mode successfully and has important value to the teaching of professional core courses, which are difficult to be learned. In this study, 80 freshmen majoring in Road and Bridge Engineering Technology at Yellow River Conservancy Technical Institute in Henan Province of China were selected as research objects, and Road Survey Design and Lofting was chosen as the teaching course. Under these circumstances, a teaching experiment comparison was designed. The experimental group used flipped classroom technology based on Attention, Relevance, Confidence, and Satisfaction (ARCS) motivation model theory, while the control group used the traditional teaching mode. Research results demonstrate that before the experiment, the learning outcomes of two groups in Road Survey Design and Lofting were basically consistent (P=0.908>0.05) without obvious differences. After finishing the experiment, the post-test results of the control group have not improved significantly compared with the pre-test results (P=0.0938>0.05). However, the post-test results of the experimental group have improved significantly compared with the pre-test results (P < 0.001). The average scores of the experimental group are far higher than that of the control group, thus indicating the evident progress of the experimental group. Noticeable differences in the post-test results between the experimental group and the control group are observed (P < 0.001). The research results are of great significance to enriching the teaching mode of core application courses for engineering majors in university, as they provide evidence that the flipped classroom increases the learning interests and motivation of students and demonstrate the teaching effect of flipped classroom technology in universities.

Authors: Shi Lei , Fan Cunjia
Published: March 2023

If the learning resource recommendation method fully considers the efficiency improvement of college students' online independent learning, it can save college students' learning energy and improve their learning quality, but also can promote students to develop such learning attitudes as active participation, willingness to explore and frequent practices. Therefore, this article studies the learning resource recommendation method for improving the efficiency of college students' online independent learning. This article quantitatively evaluates the learning efficiency of college students in the process of online independent learning, and takes the evaluation results as a reference for learning resource recommendation methods. The capsule network combined with self-attention routing algorithm is used to represent the various demands of college students' online independent learning with multiple vectors, and the sequence information layer based on Transformer model is set up to construct the learning resource recommendation model. Experimental results verify the effectiveness of the model.

Published: March 2023

Conservation and development projects that prescribe the participation of local stakeholders in decision-making around the sustainable management of their own ecosystems have become commonplace in Madagascar in recent decades, as have scholarly critiques questioning the likelihood that such “community-based conservation” (CBC) efforts can achieve the win-win scenarios they purport to offer Malagasy communities and ecosystems. This article, co-authored by differently positioned collaborators, documents the history of exchanges that have proven fundamental to the development and maintenance of one CBC project in northern Madagascar, focusing especially on the value of ongoing interpersonal relations among community members and external partners.

Dans la décision QPC du 25 novembre 2022, le Conseil constitutionnel valide, au nom de la lutte contre l’immigration illégale, la constitutionnalité des contrôles d’identité sur l’ensemble du territoire de Mayotte. En procédant à un revirement de jurisprudence, il considère que l’absence de zones limitées de contrôles d’identité, contestée par la requérante, n’est contraire ni au principe d’égalité territoriale en matière d’exercice des droits et libertés, ni à la liberté d’aller et venir.
SOI Technology in Designing Low-Power VLSI Circuits
Authors: P. Srividya
Published: March 2023

At present, the transistor size is reduced to a few tens of nanometers, as larger transistors demand a large die area and power. Power is an important design parameter in multi-gigahertz communication and ASIC/SOC designs. To deliver higher performance with lower power, various technologies are adopted in semiconductor industry. SOI is one such technology that helps in achieving higher performance. It offers a platform to integrate digital and RF circuit onto a single chip. Adopting SOI technology, faster chips with lesser power can be designed. This extends the battery life of handheld devices. The SOI structure is comparable to MOSFET except for an added buried oxide (Box) layer beneath the device region. The Box layer isolates the top and the base silicon layers and reduces the junction capacitances. This reduction accelerates the speed, lowers the power consumption, allows higher transistor stacking, and improves the device performance. These capabilities have led SOI usage in RF circuits. This chapter discusses the SOI technology in building energy- and power-efficient designs.
