Case technology based on art as a way to form communicative competence in future teachers of pre-school and primary education

The article considers formation of communicative competence in future teachers of primary and pre-school education with the help of case technology in the process of studying psychological and pedagogical disciplines from the point of view of all three structural components of communication: perceptive, communicative and interactive. The author examines the structure and components of communicative competence which have been identified by experts in this field; analyzes the features of case technology as an interactive approach to teaching students of pedagogical universities which connects theory with practice and promotes the development of future teachers’ professional skills and qualities important for productive person-centered pedagogical communication with children; describes the experience of creating and using case technology for teaching students at Moscow State Pedagogical University. The facilitated discussion method is analyzed; the role of paraphrase is revealed from the point of view of speech development of both the future teacher and the child. The focus is made on the development of students’ facilitative skills and qualities which are necessary for a teacher for person-centered communication in the conditions of humanization of education. The article provides examples of cases and discusses the results of this approach. The students’ feedback on the application of this approach is also provided. In order to facilitate formation of communicative competence using case technology, a manual of psychological and pedagogical communication was developed together with the students. The manual includes interactive teaching methods, practical exercises and cases based on works of art and has been actively used during several years. The article contains examples of such cases from the manual for illustrative purposes.
3D Face Morphing Attacks: Generation, Vulnerability and Detection

Face Recognition systems (FRS) have been found to be vulnerable to morphing attacks, where the morphed face image is generated by blending the face images from contributory data subjects. This work presents a novel direction for generating face-morphing attacks in 3D. To this extent, we introduced a novel approach based on blending 3D face point clouds corresponding to contributory data subjects. The proposed method generates 3D face morphing by projecting the input 3D face point clouds onto depth maps and 2D color images, followed by image blending and wrapping operations performed independently on the color images and depth maps. We then back-projected the 2D morphing color map and the depth map to the point cloud using the canonical (fixed) view. Given that the generated 3D face morphing models will result in holes owing to a single canonical view, we have proposed a new algorithm for hole filling that will result in a high-quality 3D face morphing model. Extensive experiments were conducted on the newly generated 3D face dataset comprising 675 3D scans corresponding to 41 unique data subjects and a publicly available database (Facescape) with 100 data subjects. Experiments were performed to benchmark the vulnerability of the proposed 3D morph-generation scheme against automatic 2D, 3D FRS, and human observer analysis. We also presented a quantitative assessment of the quality of the generated 3D face-morphing models using eight different quality metrics. Finally, we propose three different 3D face Morphing Attack Detection (3D-MAD) algorithms to benchmark the performance of 3D face morphing attack detection techniques.
MOHASA: A Dynamic Video Synopsis Approach for Consumer-based Spherical Surveillance Video

Using spherical cameras for video surveillance applications can solve the problems faced by traditional cameras in a multi-camera setup. Video synopsis is an object-based approach for reviewing a long recorded video through an optimization process. From the literature review, it is observed that Aquila Optimizer (AO) algorithm has a powerful global search capability but it can easily be trapped in a local optimum. Hence, an improved multiobjective hybrid AO with Simulated Annealing (SA), MOHASA, is introduced. The most challenging situation of using spherical cameras is the Fear of Missing out (FOMO), i.e., choosing to view one portion forces to miss the other portions of the scene. It is solved by dynamically generating video synopsis using both spatial and temporal summarization. Also, a new frame packing constraint has been integrated into the objective function to better understand spherical scenes. Experimental analysis shows that the proposed framework outperforms the state-of-the-art works.
Federated Submodular Maximization with Differential Privacy

Submodular maximization is a fundamental problem in many IoT applications, such as sensor placement, resource allocation, and mobile crowdsourcing. Despite being intensively studied over the last two decades, the problem of submodular maximization has not yet been considered in an emerging federated computation setting. In this paper, we first comprehensively study federated submodular maximization, where a set of clients aims to cooperate in finding a set of items to maximize a monotone submodular function under the orchestration of a central server while providing strong privacy guarantees for their sensitive data. We consider the problem in a client-level differential privacy setting: the server is not necessarily trusted and the clients should perturb their results locally before sending them to the server. Specifically, we propose a novel approximation algorithm for federated submodular maximization by incorporating client-level differential privacy mechanisms and decomposed function evaluations into the greedy algorithm, along with two heuristics to further reduce the privacy budget, computational cost, and communication overhead. Finally, we perform extensive experiments to demonstrate the effectiveness and efficiency of our proposed algorithms.
Operation History Estimation and Its Application to Multi-Degraded Image Restoration

Shared images obtained from the web and social platforms could be degraded by several operations, compromising their quality and reliability for consumers. Existing image restoration algorithms primarily focus on single degraded images with known degradation types, while limited research has been done on multi-degraded image restoration with unknown degradation types. Additionally, existing methods assess image reliability by detecting whether the image has undergone specific single operations using classification models. However, accurately estimating the complete operation history of an image still remains challenging. These limitations may restrict their practical use in consumer applications. To address these issues, in this work, we propose a novel framework that utilizes operation history estimation to enhance the reliability and quality of multi-degraded images. First, we develop a deep network based on the machine-translation mechanism to estimate the operation history experienced by the input multi-degraded image, including operation types, parameters, and their order. Specifically, a self-attention scheme and a cross-attention scheme are designed to capture both the internal correlations among operations and parameters and their interactive relationships. Second, we propose applying our operation history estimation scheme to multi-degraded image restoration, utilizing the estimated operations and associated parameters as prior information to assist the restoration process. Extensive experimental results demonstrate that our framework achieves excellent performance in operation history estimation and multi-degraded image restoration, ultimately improving the reliability and quality of images in consumer applications.
Quality Harmonization for Virtual Composition in Online Video Communications

Recent years have witnessed strong demands for video composition in online video communications, enabling a series of new functionalities for video conferencing including virtual conference rooms, virtual reunions, and virtual backgrounds. In video composition, typically the foreground videos including the human bodies and faces are subject to compression due to the constrained bandwidth, whereas the virtual background is uncompressed and in pristine quality. The disharmony caused by the incoherent quality of foreground and background, which may worsen the quality of experience, has not been extensively studied. In this paper, we focus on this particular problem and present an image quality harmonization framework. Our principle is to align the quality of the background with that of the foreground such that they share similar levels of distortion. This is achieved by inferring the quantization parameter for background compression based on the foreground information. In particular, we aim to learn the quality and compression parameters in a self-supervised manner without laborious human annotation. Furthermore, a large dataset is constructed to provide sufficient training samples and testing scenarios for validation. The composite videos show superior harmonized quality in both quantitative and qualitative comparisons, demonstrating the effectiveness of the proposed framework.

The Political Economy of Rentier States: Understanding Barriers on ‎Economic Reform and Integration in GCC States

The GCC states’ high dependence on the hydrocarbon sector does not reflect a sustainable ‎economy. Therefore, it is demanded that those states reform the economic system that has long ‎been preserved and accelerate economic integration in the region to reduce ‎oil dependence. This article aims to analyze the hindrances to the economic reform ‎program and the intention to achieve economic integration within the rentier state in the Arab ‎Gulf states. This article uses a qualitative method through an explanatory and descriptive ‎approach to elaborate on the issues. This study indicates that a comprehensive economic ‎reform in GCC countries is hard to implement due to the existing political structure and socio-‎cultural conditions. Were to reform the economic system totally, rulers would have a dilemma regarding the regime's sustainability. Meanwhile, the move towards economic integration within the GCC countries remains unachievable due to such unresolved issues as mistrust among member countries, powerless GCC’s structural organization, and the lack of ‎interdependency-complex in pursuing wealth and prosperity

Error analysis on factorization and the effect of online individualization classes

In this paper, we analyzed the misconceptions and errors incurred during factorization learning, and also, studied whether online individualization classes had a positive effect on students' mathematical achievement. The experiment was conducted for 4 weeks (16 times in total) on middle school juniors in rural areas of Gyeonggi Province, where the influence of private education was small. In the class, the ‘Google Classroom’ was used as a LMS, the video lecture was uploaded to YouTube, and the teacher interacted with the students through “Zoom” and “Facetalk”. In the online class situation, students' assignments and test answers were checked in real time through 'Google Classroom', and immediate feedback was provided to the experimental class group's students. However, for the control group students, feedback was provided only to those who desired. A total of 7 achievement evaluations were conducted in the order of pre-test, formative evaluation (5 times), and post-test to confirm the change in students' ability improvement and achievement. Through the formative evaluation analysis, it was possible to grasp the types of errors and misconceptions that occured during the factorization process. Students' errors were divided into four types: theorem or definition distortion error, functional errors such as calculation, operation, and manipulation, errors that do not verify the solution, and no response. As a result of ANCOVA, the two groups did not show any difference from the 1st to 4th formative assessment. However, the 5th formative assessment and post-test showed statistically significant differences, confirming that online individualization classes contributed to improvemed achievement.
A study on Analyzing the Difference Factors Occurred in the Pre-service Secondary Teachers on the Mathematical Noticing and the Method for Improving Practical Knowledge

Recently, in the field of mathematics education, mathematical noticing has been considered as an important element of teacher expertise. The meaning of mathematical noticing is the ability of teachers to notice and interpret significant events among various events that occur in mathematics class. This study attempts to analyze the differences of pre-service secondary teachers’ mathematical noticing and confirm the factors that cause the differences between them. To accomplish this, the items on class critiques were established to identify pre-service secondary school teachers’ mathematical noticing, and each of 18 pre-service secondary mathematics teachers were required to write a class critique by watching a video in which their micro-teaching was recorded. it was that the teachers’ mathematical noticing be identified by analyzing their class critiques in three dimensions such as actor, topic, and stance. As a result, there were differences in mathematical noticing between pre-service secondary mathematical teachers in terms of topic and stance dimensions. Based on the result, the difference factors were occurred in the teachers on the mathematical noticing, and namely those factors were subject matter knowledge, pedagogical content knowledge, curricular knowledge, beliefs, experiences, goals, and practical knowledge.
Musical Heuristics: The Role of Fictions in the Process of Musical Creation and its Pedagogy

Abstract This article is a contribution to the understanding of fictions and the determining role they play both in musical creation and in its pedagogy. A previous philosophical investigation is indispensable to enter into the subject: starting from Kant's Critique of Pure Reason, we are confronted with what he calls heuristic fictions, undemonstrable as phenomena but at the same time indispensable to indicate the path that every project must follow. A classification of fictions is proposed below, thus distinguishing those that belong to the domain of philosophy and science from those that apply to art. Two psychological theories frame the production and development of artistic fictions: Winnicott's theory of the transitional object and Ehrenzweig's theory of the hidden order of arts. The work continues with a presentation of musical heuristics, its methods and applications. Pedagogy is undoubtedly the field where the theoretical background developed in this article can be directly applied. A pedagogical work plan is presented, to facilitate the task of teachers, music teachers and creative pedagogues.
Termination in Concurrency, Revisited

Termination is a central property in sequential programming models: a term is terminating if all its reduction sequences are finite. Termination is also important in concurrency in general, and for message-passing programs in particular. A variety of type systems that enforce termination by typing have been developed. In this paper, we rigorously compare several type systems for π -calculus processes from the unifying perspective of termination. Adopting session types as reference framework, we consider two different type systems: one follows Deng and Sangiorgi’s weight-based approach; the other is Caires and Pfenning’s Curry-Howard correspondence between linear logic and session types. Our technical results precisely connect these very different type systems, and shed light on the classes of client/server interactions they admit as correct.
