Traditionally, clinician educators are tasked with the responsibility of training future physician workforce. However, there is limited identification of skills required to fulfill this responsibility and a lack of consensus on effective faculty development for career growth as a clinician educator. The newly released Accreditation Council of Graduate Medical Education (ACGME) Clinician Educator (CE) Milestones framework outlines important skills for clinician educators and provides the opportunity to create robust faculty development. In this paper, members of the Society of General Internal Medicine Education Committee discuss the importance of these CE Milestones, outline the novel themes highlighted in the project, and provide recommendations for proper application on both the individual and institutional levels to optimize faculty development. The paper discusses strategies for how to apply the CE Milestones as a tool to create a culture of professional growth and self-directed learning. Using a reflective approach, CE faculty and mentors can identify areas of proficiency and opportunities for growth, thereby creating individualized professional development plans for career success. Institutions should use aggregate CE Milestones data as a needs assessment of their faculty "population" to create targeted faculty development. Most importantly, institutions should not use CE Milestones for high-stakes assessments but rather encourage reflection by CE faculty and create subsequent robust faculty development programs. The ACGME CE Milestones present an exciting opportunity and lay an important foundation for future CE faculty development. [ABSTRACT FROM AUTHOR]

The paper introduces the student‐coined term digital instinct which describes students' disposition to resorting to digital technology for solving problems and doing school assignments. Taking cues from the term digital instinct, the paper describes a student perspective on digital literacy emerging from 100 lived experience descriptions and interviews with 37 Danish upper secondary students. The findings show that students' digital practice is characterised by experience‐based, intuitive and familiar use of technologies. Most notably, students employ digital technologies as cognitive partners that help them carry on with assignments that they initially did not understand, but that they were able to complete with the help of the computer. The study examines the nature of this partnership through the words of the students and identifies how technologies expand student agency but fall short of a reflective use of digital technologies. Recognising the strengths and weaknesses of students' digital practices may inform the concept of digital literacy and encourage teachers to acknowledge the digital instinct as a steppingstone to foster students' reflective use of digital technologies. Practitioner notesWhat is already known about this topic Students have inadequate command of digital literacies as described in curricular terminology.Students have positive as well as negative perceptions of the value and usefulness of digital technologies in school.Students both over‐ and underestimate their own digital literacies.What this paper adds Students have a fundamental utilitarian conception of digital technologies that either make schoolwork easier or more difficult, and they do not articulate that their use of digital technologies provides them with digital literacies.Students' conception of a digital instinct describes an intuitive and familiar, albeit unreflected, use of technologies where students employ experience‐based and self‐taught methods for using digital technologies.The digital instinct accounts for a feeling of agency among students, manifested in a widespread confidence that they can do assignments and solve problems when they make use of their computer.Implications for practice and/or policy Curricular terminologies struggle to capture what students can and cannot do with technology, and how much they understand the underlying technology.Teachers can involve and build on students' experience‐based digital practices as a starting point for developing digital literacy among students—also as an entry to a curricular perspective.Teachers should acknowledge students' conception of a 'digital instinct' as an important disposition in its own right.

Background: Both socially regulated learning and cognitive quality are important factors affecting collaborative knowledge building, but the current research lacks a joint quantified evaluation method that combines these two aspects. Objectives: Based on the existing framework, we proposed a joint evaluation method for regulated learning and cognitive quality in collaborative knowledge building, and further extracted the evaluation indicators. Methods: This study involved 74 learners enrolled in a course named 'the Application of Modern Educational Technology' as the subject of study, and made a case analysis with this method. Results and Conclusions: First, the indicators of this joint evaluation method could complement the indicators of traditional frequency statistics methods and facilitate an analysis of regulated learning and cognitive quality in collaborative knowledge building. Second, the group with a higher proportion of high‐level cognitive quality and socially shared regulation in collaborative knowledge building achieved better final scores. Finally, four types of groups were obtained through clustering: excellent, risky, mixed group, and highly collaborative group. This study introduced a joint evaluation method for regulated learning and cognitive quality in collaborative knowledge building and provides suggestions for future research. Lay Description: What is currently known about this topic?: Online collaborative knowledge building is increasingly important.Regulated learning and cognitive quality are considered very important for successful collaborative learning.Without quantitative methods, it is difficult to assess regulated learning and cognitive quality during collaborative knowledge building in a timely manner. What does this paper add?: This paper provided a joint evaluation method of regulated learning and cognitive quality (JERC) for online collaborative knowledge building.A case study was conducted to identify JERC's usefulness. Using descriptive statistics and visualization, it was determined that indicators of JERC can not only capture the state of cognitive quality and regulated learning status, but also elucidate the nature of that status (i.e., comprehensive, dynamic, cyclical).Through clustering analysis, four distinct groups were identified, each exhibiting different characteristics and moving patterns of regulated learning and cognitive quality over time. These patterns indicate that the quality of cognitive and regulatory learning cannot be determined solely by behavioural frequency. Moreover, an excessive proportion of individual regulation cannot predict better learning performance. Implications for practice: A computable representation model of regulated learning and cognitive quality was constructed to support automated perception and intervention in regulated learning and cognitive processing.With JERC, it is possible for researchers to capture, process, analyse and predict dynamic data to examine online collaborative knowledge building combined with shared physiological arousal events.The results of JERC can be used by researchers to develop advanced techniques, such as AI deep learning, for designing adaptive supports that can foster students' online collaborative knowledge building.

This paper describes authors' experience with designing and teaching a new course on "Fundamentals of Automation Engineering", based on a hybrid Project-Based Learning approach. The proposed challenge for students was to develop a low-cost Material Handling Machine, equipped with basic control functions. The project was executed in three stages, with different activities/tasks performed during each stage, which finally led to successful completion of the challenge. Detailed course file containing syllabus, learning objectives, assessment rubric, project goals, and deliverables was provided to students at first stage. Handouts and assignments were also provided weekly to students, which required extensive use of library resources (self-learning). Feedback survey was conducted fortnightly and suggestions were considered for course improvement. In this paper, authors discuss course organization, learning and assessment activities, and perception of students. [ABSTRACT FROM AUTHOR]

Knowledge diffusion in regional innovation ecosystems is an important factor that influences the regional innovation efficiency. In regional innovation ecosystems under digital empowerment, the knowledge diffusion enables the optimal allocation of innovation resources and promotes the sustainable development and ecological evolution of regional innovation ecosystems. In this paper, a SEIR (Susceptible–Exposed–Infected–Recovered) model is proposed for knowledge diffusion in regional innovation ecosystems under digitization. The basic reproduction number of the proposed model is calculated and its stability is validated. Finally, the expressions for the optimal control system and the optimal control parameters are presented. According to the research conclusions of this paper, the knowledge-diffusion ability of innovation agents in an innovation ecosystem affects the knowledge diffusion in a system; the contact rate between innovation agents affects the efficiency of knowledge diffusion in the system and the structure of the system; the digital transmission ability of innovation agents affects the breadth of knowledge diffusion in the system; and the self-learning ability of innovation agents affects the efficiency of knowledge diffusion in the system.The digital technologies help heterogeneous innovation agents in regional innovation ecosystems to break down the knowledge silos. At the same time, the digital technologies enhance the ability of innovation agents to absorb and learn knowledge in regional innovation ecosystems under digitization, thereby increasing the infection rate of knowledge diffusion in such systems.These conclusions extend the theoretical boundaries of innovation ecosystems and knowledge diffusion and offer management implications for enterprises and governments in decision-making.

With the high proportion of renewable energy sources and power electronic devices accessed in the distribution network, the harmonic pollution problem has become increasingly serious. The traditional centralized harmonic mitigation strategy has difficulty in effectively dealing with these scattered and random harmonics. Therefore, a distributed harmonic mitigation strategy based on the dynamic points incentive of blockchain communities is proposed in this paper. Firstly, a comprehensive voltage sensitivity partitioning method with harmonic weight differentiation is proposed to realize the reasonable partitioning of each control node and controlled node in the distribution network concerning variability in harmonic components and their distribution. Then, a harmonic mitigation strategy based on the dynamic integral excitation of self-learning algorithms is constructed to promote self-organized optimization and active distributed coordinated control of mitigation devices. The strategy ensures that the total harmonic voltage distortion rate of each node meets the requirements by adjusting the partitioned collaboration to realize optimal harmonic mitigation. By setting optimized partitions in different scenarios and conducting simulation verification, the results demonstrate the effectiveness of the strategy in this paper. It stimulates synergy between devices through a dynamic incentive mechanism and significantly reduces the total harmonic voltage distortion rate across various test scenarios, reflecting the adaptability of the harmonic mitigation method presented.

Purpose: This paper aims to investigate the relative translational control for multiple spacecraft formation flying. This paper proposes an engineering-friendly, structurally simple, fast and model-free control algorithm. Design/methodology/approach: This paper proposes a tanh-type self-learning control (SLC) approach with variable learning intensity (VLI) to guarantee global convergence of the tracking error. This control algorithm utilizes the controller's previous control information in addition to the current system state information and avoids complicating the control structure. Findings: The proposed approach is model-free and can obtain the control law without accurate modeling of the spacecraft formation dynamics. The tanh function can tune the magnitude of the learning intensity to reduce the control saturation behavior when the tracking error is large. Practical implications: This algorithm is model-free, robust to perturbations such as disturbances and system uncertainties, and has a simple structure that is very conducive to engineering applications. Originality/value: This paper verified the control performance of the proposed algorithm for spacecraft formation in the presence of disturbances by simulation and achieved high steady-state accuracy and response speed over comparisons.

Winnicott's unique contributions to a psychoanalytic theory of depression are not as familiar as Freud and Klein's writings. I concentrate on six areas: depression as a developmental achievement which denotes unit status; the role of destruction which arises from love (as opposed to hate which for Winnicott is a more mature affect); the importance of contributing‐in and the response of the (m)other in recovery from depression; the startling idea that the patient seeks out the analyst's depression; some thoughts on the differences between Winnicott and Freud and Klein; and lastly, the effect of depression on the development of self, creativity and the capacity to play. Winnicott does not shirk the darker side of being human, but at the same time he offers us a hopeful picture. [ABSTRACT FROM AUTHOR]

Purpose: This research paper aims to explore how secondary school-aged business owners utilise social media to engage in informal learning. The authors make use of the concept of a self-directed experiential learning cycle to empirically explore adolescents' entrepreneurial learning processes without formal guidance or curriculum. Design/methodology/approach: The study adopts a one-on-one interview approach with a critical incident technique in interviewing to examine the experiences of 10 Grade 9–11 business owners who run social media-based businesses on Instagram. Findings: The results demonstrate that student business owners were able to capitalise on social media for venture creation and informal learning. They effectively engaged in experiential learning cycles with active help-seeking and mentorship in response to challenges in their business journey. A variety of resources within social media, their social circle and the internet were employed by students, highlighting the role the self-directed element plays in their experiential learning process. Practical implications: The research urges institutions to recognise the potential of informal learning on social media and offer more support to strengthen students' learning. Originality/value: This research represents the first exploratory study on the potential of school-age teens' self-initiated informal entrepreneurial learning while testifying the theory of the self-directed experiential learning cycle in the context of social media businesses. The study offers novel insights into the fields of students' informal learning, entrepreneurial learning and social media learning. [ABSTRACT FROM AUTHOR]

This paper examines, through a survey, the level of education and training in data verification among directors and department heads in the Spanish media (n=190). Findings reveal a limited level of training in this area, mainly acquired through in-house courses or self-directed learning, resulting in a limited knowledge and use of specific digital tools for information verification. Despite this, respondents generally hold a positive self-assessment of their verification skills, with (almost) all expressing a willingness to participate in training initiatives.

Given calls to decolonise engagement with Indigenous communities, this article explores how allied researchers can participate in self-determined learning with Indigenous Peoples. Drawing on over a decade of experience within an action-research collective in a Mapuche context, the authors suggest that allied researchers can accompany Indigenous-led co-design in a manner that not only strengthens genuine Indigenous participation but also fosters mutual and collective learning from within the co-creative processes themselves. Lake Budi, a biocultural hotspot in the Pacific coast of Northern Patagonia, Chile, is a coastal wetland habitat for hundreds of endemic and migratory species and the ancestral homeland for the Mapuche-Lafkenche (∼15,000) who, through grassroots learning, are determining practical steps towards restoring their territory and its self-governance for kvmemongen. This Mapuche concept refers broadly to enacting forms of living well together, humans and non-humans. As allied participants in a Mapuche-led codesign collective since 2013, in this paper, we focus on exploring key “moments of mutual learning” within this longer-than-usual co-design process. Each of these moments involved collective learning that required interaction and feedback loops across diverse areas of expertise, made possible over longer and flexible rhythms and periods. Tools, protocols, and methods gradually take shape in such a process through mutual learning opportunities provided by relationship building, cultural immersion, community-led protocols, decision-making, and evaluation mechanisms. This work suggests a new understanding of the involvement of allied researchers in Indigenous-led co-design as an emerging and increasingly relevant form of grassroots mutual learning toward climate resilience.

Brain-computer interface (BCI) provides direct communication and control between the human brain and physical devices. It is achieved by converting EEG signals into control commands. Such interfaces have significantly improved the lives of disabled individuals suffering from neurological disorders—such as stroke, amyotrophic lateral sclerosis (ALS), and spinal cord injury—by extending their movement range and thereby promoting self-independence. Brain-controlled mobile robots, however, often face challenges in safety and control performance due to the inherent limitations of BCIs. This paper proposes a shared control scheme for brain-controlled mobile robots by utilizing fuzzy logic to enhance safety, control performance, and robustness. The proposed scheme is developed by combining a self-learning neuro-fuzzy (SLNF) controller with an obstacle avoidance controller (OAC). The SLNF controller robustly tracks the user's intentions, and the OAC ensures the safety of the mobile robot following the BCI commands. Furthermore, SLNF is a model-free controller that can learn as well as update its parameters online, diminishing the effect of disturbances. The experimental results prove the efficacy and robustness of the proposed SLNF controller including a higher task completion rate of 94.29% (compared to 79.29%, and 92.86% for Direct BCI and Fuzzy-PID, respectively), a shorter average task completion time of 85.31 s (compared to 92.01 s and 86.16 s for Direct BCI and Fuzzy-PID, respectively), and reduced settling time and overshoot.

Student academic achievement is an important indicator for evaluating the quality of education, especially, the achievement prediction empowers educators in tailoring their instructional approaches, thereby fostering advancements in both student performance and the overall educational quality. However, extracting valuable insights from vast educational data to develop effective strategies for evaluating student performance remains a significant challenge for higher education institutions. Traditional machine learning (ML) algorithms often struggle to clearly delineate the interplay between the factors that influence academic success and the resulting grades. To address these challenges, this paper introduces the XGB-SHAP model, a novel approach for predicting student achievement that combines Extreme Gradient Boosting (XGBoost) with SHapley Additive exPlanations (SHAP). The model was applied to a dataset from a public university in Wuhan, encompassing the academic records of 87 students who were enrolled in a Japanese course between September 2021 and June 2023. The findings indicate the model excels in accuracy, achieving a Mean absolute error (MAE) of approximately 6 and an R-squared value near 0.82, surpassing three other ML models. The model further uncovers how different instructional modes influence the factors that contribute to student achievement. This insight supports the need for a customized approach to feature selection that aligns with the specific characteristics of each teaching mode. Furthermore, the model highlights the importance of incorporating self-directed learning skills into student-related indicators when predicting academic performance. [ABSTRACT FROM AUTHOR]

Hyper-heuristic algorithms are known for their flexibility and efficiency, making them suitable for solving engineering optimization problems with complex constraints. This paper introduces a self-learning hyper-heuristic algorithm based on a genetic algorithm (GA-SLHH) designed to tackle the logistics scheduling problem of prefabricated modular cabin units (PMCUs) in cruise ships. This problem can be regarded as a multi-objective fuzzy logistics collaborative scheduling problem. Hyper-heuristic algorithms effectively avoid the extensive evaluation and repair of infeasible solutions during the iterative process, which is a common issue in meta-heuristic algorithms. The GA-SLHH employs a genetic algorithm combined with a self-learning strategy as its high-level strategy (HLS), optimizing low-level heuristics (LLHs) while uncovering potential relationships between adjacent decision-making stages. LLHs utilize classic scheduling rules as solution support. Multiple sets of numerical experiments demonstrate that the GA-SLHH exhibits a stronger comprehensive optimization ability and stability when solving this problem. Finally, the validity of the GA-SLHH in addressing real-world decision-making issues in cruise ship manufacturing companies is validated through practical enterprise cases. The results of a practical enterprise case show that the scheme solved using the proposed GA-SLHH can reduce the transportation time by up to 37%. [ABSTRACT FROM AUTHOR]

This paper presents two empirical studies. Study 1 validated a survey on L2 self-regulated strategies in writing in a multimedia environment. Study 2 examined the relationship of Chinese students' working memory to their L2 English proficiency and self-regulated learning (SRL) strategies in multimedia writing. A total of 400 Chinese university students participated in Study 1, and they responded to a survey on SRL strategy use in multimedia writing. A total of 406 Chinese university students attended Study 2. They completed the survey and an operation span task (a measure of working memory). All the participants' English proficiency was evaluated using the College English Test-4, a standardized test for undergraduate students in China. Results of Study 1 revealed a 5-factor SRL strategy structure consisting of goal setting, strategic planning, elaboration, self-evaluation, and help seeking. Results of Study 2 suggested the predicted effects of self-regulated strategies, working memory, and L2 proficiency on L2 writing performance. Findings also demonstrated the moderation effects of English proficiency on the effects of self-regulated writing strategies. Implications for enhancing writing in multimedia environments are provided. 本文汇报了两项实证研究。第一项研究验证了在多媒体环境中进行二语自主调控写作策略的调查问卷。第二项研究探讨了中国学生的工作记忆, 英语水平以及多媒体写作中的自主调控写作策略之间的关系。共有400名中国大学生参与了第一项研究, 并回答了关于多媒体写作中自主学习策略使用的调查问卷。第二项研究有406名中国大学生参与。他们完成了调查问卷和操作跨度任务(一种工作记忆测量方法)。所有参与者的英语水平都通过一项中国本科生的标准化考试, 即大学英语四级考试, 进行了评估。第一项研究的结果显示, 自主学习策略包括目标设定、战略规划、详细阐述、自我评估和求助, 共五个因素。第二项研究的结果表明, 自主调控策略、工作记忆和英语水平对二语写作表现具有预测效应。研究结果还显示, 英语水平对自主调控写作策略的效果具有调节作用。该研究对于提升多媒体环境下的写作具有重要借鉴意义。 PLAIN LANGUAGE SUMMARY: We reported the findings of two empirical studies. In Study 1, we tested a survey to see how well it measured learners' self-regulated strategies in a multimedia environment. In Study 2, we looked at learners' working memory, proficiency, and learners' self-regulated strategies in a multimedia environment. The results of Study 1 showed that there are five main strategies students use when writing. They include goal setting, strategic planning, elaboration, self-evaluation, and help-seeking. The results of Study 2 showed that learners' working memory, proficiency, and learners' self-regulated strategies are essential to their writing performance. The results also supported the idea that English proficiency plays a moderating role in the relationship between self-regulation and writing. When English proficiency was low, self-regulation had a greater impact on writing performance; conversely, when English proficiency was high, self-regulation had a smaller effect on writing performance. However, the present study did not identify a statistically significant interaction effect between working memory and self-regulation. Working memory may not affect self-regulation in students' writing outcomes. This study, thus, contributes to teachers', teacher educators', policy makers', and practitioners' knowledge in terms of self-regulation, working memory, and proficiency in a multimedia writing environment.

A first-class curriculum stands at the heart of talent education, playing a pivotal role in achieving the educational objectives. Against the backdrop of the “Double Frist-Class” initiative, this paper examines the construction approach and practices of the provincial-level premier course in Inorganic and Analytical Chemistry at Jianghan University. Educational reforms have been implemented in three key areas: the integration of professional and ideological education, consolidation of teaching content and resources, and the blending of online and offline instructional methods. This has led to the development of a “MOOCs + Flipped Classroom + Problem-Based-Learning (PBL)” instructional model and a “Three-Phase, Seven-Step” teaching methodology, both aimed at enhancing students’ engagement and fostering their self-directed learning skills. These measures offer valuable insights for the development of Inorganic and Analytical Chemistry courses at local colleges and universities. [ABSTRACT FROM AUTHOR]

Pre-laboratory preparation is a crucial component in experimental instruction. The scientific design and effective implementation of preparation not only directly impact the students’ learning effectiveness and the teachers’ instructional efficacy, but also play a pivotal role in cultivating students’ cognitive ability and inquiry spirit, acting as a small lever that can yield significant educational benefits. This paper presents the exploration and summary of an approach adopted by the General Chemistry Experimental Course Team at Wuhan University, which utilizes a blend of online and offline resources to assist lower-year students in their laboratory preparation. It highlights the innovative use of interactive lecture notes and a “Six-Step” preparatory teaching model, aimed at subtly fostering students’ critical thinking and self-learning abilities for steady enhancement.

Criminal forensics in an Internet-of-Things (IoT) environment often requires complex investigations because IoT devices usually generate a large amount of electronic data, especially image data, which brings great difficulties to traditional digital forensic methods. Therefore, designing a secure management solution for image data and making it to be image evidence available in court is a new challenge. In this paper, we present a new secure image evidence management framework based on multi-bits digital watermarking and blockchain. In this framework, we first propose a flexible and robust self-learning based watermark embedding algorithm, which can embed both image marks and binary messages into the latent space of the input images and also improve the resistance of a broad range of attacks (geometric transform, JPEG, noise, etc.) to the watermarked images. And then, we design a smart contract resided in blockchain, which can achieve safe storage and automatically authentication of embedded watermarks. The experimental results on both watermarking algorithm and smart contracts have demonstrated the feasibility and efficacy of the proposed framework. [ABSTRACT FROM AUTHOR]

The advancement of intelligent technology has propelled the development of smart unmanned vessels into a new phase. To address the urgent demands of current smart ship development, this paper develops a comprehensive ship digital twin system based on a virtual-real mapping algorithm, focusing on the fundamental elements of digital twin model construction. Using the smart unmanned experimental ship Dolphin 1 as a prototype, a digital twin virtual model is proposed. This system leverages real-time internal and external data from the entire vessel to track its navigational status, performance indicators, sailing trends, and surrounding flow field information, offering coordinated "human-machine" navigation assistance. Based on historical data collected from the vessel's long-term navigation, a real-time precise prediction of the vessel's navigational state and hydrodynamic performance is conducted using physics-informed neural network algorithm. This establishes a self-learning iterative virtual-physical mapping model that enables autonomous updates and evolution. As the real navigation data of the vessel continuously update, the virtual model can more accurately simulate the vessel's state in real time. The proposed digital twin model has been tested through sea trials under real sea conditions, demonstrating its high accuracy, robustness, and potential for enhancing navigational safety and efficiency. This system marks a significant step forward in the integration of digital twin technology with maritime navigation, providing a valuable tool for the future development of smart shipping.

Background: Some studies have researched the correlation between flipped learning and cognitive learning outcomes; however, there is a paucity of research elaborating on the effects of flipped language learning on cognitive load (CL). Objectives: This study investigates the effects of using flipped learning designs (student‐led, teacher‐led and collaboration‐led) on learning outcomes and CL management during out‐of‐class activities versus during‐class activities. Methods: A mixed methods research was used to concurrently triangulate different strands of data on the effects of flipped learning designs on English as foreign language (EFL) learners' learning outcomes and CL. A total of 122 EFL learners were randomly assigned to either the control or experimental group and participated in the study. The interpretations were made based on running one‐way analysis of variance between four groups. Results and Conclusion: This study evidenced the efficacy of the interactive use of collaboration‐led flipped learning design over student‐led and teacher‐led designs for improving learning outcomes and lowering CL during computer‐assisted language learning (CALL) course. Pedagogically, CALL practitioners need to develop and integrate a well‐organized combination of student‐led and teacher‐led flipped learning activities for during‐class and out‐of‐class phases with respect to the CL and learning material complexity, while also considering the specific contexts and goals of their instructional settings. Theoretically, the results indicate the necessity of merging active learning and sociocultural theories into an instructional design to take advantage of the identified affordances of flipped language learning approach in terms of psychological effects (CL management) and learning effects (CALL outcomes). Lay Description: What is already known about this topic: The flipped language learning approach involves receiving online instruction outside the classroom and is a learner‐centered pedagogy. What this paper adds: This study contributes by triangulating different strands of data on the effects of flipped learning designs on learning outcomes and cognitive load.The findings highlight the effectiveness of collaboration‐led design for flipped language learning, facilitating engagement in both out‐of‐class and during‐class activities. Implications for practice: The findings emphasize the importance of designing and implementing instructional designs that align with emerging educational technologies.Teachers should consider the flexibility, fluency and novelty of the learning material when designing flipped learning activities.

As it concerns remote laboratories (RLs) for teaching microcontroller programming, the related literature reveals several common characteristics and a common architecture. Our search of the literature was constrained to papers published in the period of 2020–2023 specifically on remote laboratories related to the subject of teaching microcontroller programming of the Arduino family. The objective of this search is to present, on the one hand, the extent to which the RL platform from the Hellenic Mediterranean University (HMU-RLP) for Arduino microcontroller programming conforms to this common architecture and, on the other hand, how it extends this architecture with new features for monitoring and assessing users' activities over remote labs in the context of pervasive and supervised learning. The HMU-RLP hosts a great number of experiments that can be practiced by RL users in the form of different scenarios provided by teachers as activities that users can perform in their self-learning process or assigned as exercises complementary to the theoretical part of a course. More importantly, it provides three types of assessments of the code users program during their experimentation with RLs. The first type monitors each action users perform over the web page offered by the RL. The second type monitors the activities of users at the hardware level. To this end, a shadow microcontroller is used that monitors the pins of the microcontroller programmed by the users. The third type automatically assesses the code uploaded by the users, checking its similarity with the prototype code uploaded by the instructors. A trained AI model is used to this end. For the assessments provided by the HMU-RLP, the experience API (xAPI) standard is exploited to store users' learning analytics (LAs). The LAs can be processed by the instructors for the students' evaluation and personalized learning. The xAPI reporting and visualization tools used in our prototype RLP implementation are also presented in the paper. We also discuss the planned development of such functionalities in the future for the use of the HMU-RLP as an adaptive tool for supervised distant learning. [ABSTRACT FROM AUTHOR]

Automatic question generation and automatic question answering from text is a fundamental academic tool that serves a wide range of purposes, including self-study, coursework, educational assessment, and many more. Manual construction of questions is a time-consuming and complicated process that requires experience, whereas automating the process diminishes the costs of manual question creation and fulfills the need for a persistent supply of questions for the tutors and self-evaluators. This paper uses an encoder–decoder architecture-based text-to-text transfer transformer (T5) intending to generate several types of question–answer pairs over a given context, including subjective question–answers having short and long answers, fill-in-the-blanks-type question–answers, Boolean answer (yes-or-no)-type questions, and multiple-choice question-answers. The model has been evaluated on benchmark datasets—SQuAD, QuAC, and BoolQ; over automated metrics—BLEU, ROUGE, METEOR, F1, and accuracy. The model outperformed previous baseline models, with 18.87 and 25.24 scores over BLEU-4 and METEOR metrics, respectively. The paper also demonstrates that the proposed system efficiently generates question–answer pairs where the baseline approaches struggled. The evaluation analysis also shows that the generated question–answer pairs are comparable with existing systems and even better in terms of diversity. Also, the generated questions are grammatically and contextually correct, and the answer generated matches the question in the textual context. [ABSTRACT FROM AUTHOR]

The widespread adoption of cloud computing necessitates privacy-preserving techniques that allow information to be processed without disclosure. This paper proposes a method to increase the accuracy and performance of privacy-preserving Convolutional Neural Networks with Homomorphic Encryption (CNN-HE) by Self-Learning Activation Functions (SLAF). SLAFs are polynomials with trainable coefficients updated during training, together with synaptic weights, for each polynomial independently to learn task-specific and CNN-specific features. We theoretically prove its feasibility to approximate any continuous activation function to the desired error as a function of the SLAF degree. Two CNN-HE models are proposed: CNN-HE-SLAF and CNN-HE-SLAF-R. In the first model, all activation functions are replaced by SLAFs, and CNN is trained to find weights and coefficients. In the second one, CNN is trained with the original activation, then weights are fixed, activation is substituted by SLAF, and CNN is shortly re-trained to adapt SLAF coefficients. We show that such self-learning can achieve the same accuracy 99.38% as a non-polynomial ReLU over non-homomorphic CNNs and lead to an increase in accuracy (99.21%) and higher performance (6.26 times faster) than the state-of-the-art CNN-HE CryptoNets on the MNIST optical character recognition benchmark dataset.

This paper describes (1) the reasoning behind a self-directed learning assignment in an advanced qualitative research methods course, and (2) doctoral students' experiences with that assignment. Drawing on instructor and student perspectives, a professor and four doctoral students collaborated to reflect and report on the process and product of one assignment within a course. The doctoral students approached the assignment in unique ways: delving into one specific research methodology, comparing multiple research designs, and exploring current uses of qualitative research at a research conference. The piece contributes to the body of literature about students' and instructors' experiences in graduate qualitative research methods courses and argues for providing more opportunities for students to direct their own learning in graduate coursework.

In this paper, a discrete model of delays at oversaturated intersections was established by using the graphic analysis method and a reward function. The problem of optimizing signal control at an oversaturated intersection was transformed into a Markov decision process by utilizing queue length as the state variable and choice of green ratio as the action. Following this, a self-learning method for signal optimization (SLSO) at oversaturated intersections based on deep learning (dueling Q-leaming, Dueling DQN) with priority experience replay (PER) was proposed. Moreover, dynamic learning rate and dynamic e-greedy strategy were used to accelerate convergence and achieve better model optimization. Constraints and penalties on queue length were set to avoid traffic overflow. The results of comparative simulations showed that the traditional method yielded the longest delay while the two-stage bang-bang control method led to the shortest delay, with a reduction in the delay of about 13.3%. The proposed SLSO could reduce the delay by about 12.3% and the maximum queue length by 1.7% without constraints on queuing, and by 5.1% and 13%, respectively, with constraints on queuing in place. Finally, a real-world 4-phase intersection was selected to prove that the proposed SLSO method is widely applicable. [ABSTRACT FROM AUTHOR]

Recent advances in smart connected vehicles and intelligent transportation systems are based on the collection and processing of massive amounts of sensor data. There are various internal sensors integrated into modern vehicles that are useful to monitor multiple mechanical and electrical systems, and the shift to semi-autonomous vehicles adds outward-facing sensors such as cameras, lidar, and radar. Low-cost, dependable sensing, connectivity, computational capacity, and powerful analytics are ushering in a new era of vehicle context sensing and vehicular network (VANET). However, due to latency, bandwidth, cost, security, and privacy issues, as well as the growing capabilities of edge computing devices, it is necessary to examine both edge and cloud computing in order to make informed judgments based on their contexts and performances. So, in this paper, we have proposed an architecture that focuses on an intelligent transportation system based on both Cloud and Edge computing in order to monitor and analyze vehicle sensor data and its environment; known as monitoring and analyzing as a service. Our proposed architecture is able to react in real-time to any vehicle context changes in a dynamic, adaptive, and autonomous way. It generates many plans adapted to the vehicle context that will be useful for future research to achieve a self-learning and self-adaptive system. This suggested architecture helped us improve vehicle and road safety, traffic efficiency, and convenience as well as comfort to both drivers and passengers. Also, we have reduced latency and increased bandwidth. Finally, we have approved the performance of our architecture based on different evaluation metrics. [ABSTRACT FROM AUTHOR]

Microscopic emission estimation based on driving states plays a crucial role in controlling the pollution of on-road vehicles. Existing research has evolved from fitting nonlinear models of driving cycles and emission factors to utilizing neural networks to exploit driving patterns and construct a nonlinear mapping between driving states and emission values. However, due to the small percentage of driving-cycle related to high emissions, it is still challenging to capture the vehicle emission peaks, which lead to the most noteworthy high-emission characteristics being regarded as abnormal disturbances instead. To address the issue, this paper proposes a peak-sensitive microscopic emission estimation framework characterized by sequence-to-sequence learning for on-road vehicles. Sequence-to-sequence learning emphasizes serial pattern mapping from driving sequences to emission sequences to provide more statistical constraints and reduce the estimation uncertainty brought by unstable driving behaviors. Specifically, the framework aims at capturing context features related to high emissions from sequences dynamically in an adaptive and self-learning way and is composed of a driving states embedding module and a dynamic aggregation module. Particularly, an incremental tracking loss (ITL) is proposed to adjust the incremental emissions at adjacent time steps by supervising the differences of the generated sequences, enabling the model to track sudden changes in emissions. Extensive experiments are conducted on the on-board diagnostics (OBD) dataset with 12628 sampling records collected from a heavy-duty diesel vehicle. The results show that the estimation accuracy of our proposed method is significantly better than state-of-the-art methods, and it can effectively capture high-emission peaks. [ABSTRACT FROM AUTHOR]

This paper presents a novel variant of the teaching–learning-based optimization algorithm, termed BLTLBO, which draws inspiration from the blended learning model, specifically designed to tackle high-dimensional multimodal complex optimization problems. Firstly, the perturbation conditions in the "teaching" and "learning" stages of the original TLBO algorithm are interpreted geometrically, based on which the search capability of the TLBO is enhanced by adjusting the range of values of random numbers. Second, a strategic restructuring has been ingeniously implemented, dividing the algorithm into three distinct phases: pre-course self-study, classroom blended learning, and post-course consolidation; this structural reorganization and the random crossover strategy in the self-learning phase effectively enhance the global optimization capability of TLBO. To evaluate its performance, the BLTLBO algorithm was tested alongside seven distinguished variants of the TLBO algorithm on thirteen multimodal functions from the CEC2014 suite. Furthermore, two excellent high-dimensional optimization algorithms were added to the comparison algorithm and tested in high-dimensional mode on five scalable multimodal functions from the CEC2008 suite. The empirical results illustrate the BLTLBO algorithm's superior efficacy in handling high-dimensional multimodal challenges. Finally, a high-dimensional portfolio optimization problem was successfully addressed using the BLTLBO algorithm, thereby validating the practicality and effectiveness of the proposed method.

This paper is devoted to the problem of solving a system of nonlinear equations with an arbitrary but continuous vector function on the left-hand side. By assumption, the values of its components are the only a priori information available about this function. An approximate solution of the system is determined using some iterative method with parameters, and the qualitative properties of the method are assessed in terms of a quadratic residual functional. We propose a self-learning (reinforcement) procedure based on auxiliary Monte Carlo (MC) experiments, an exponential utility function, and a payoff function that implements Bellman's optimality principle. A theorem on the strict monotonic decrease of the residual functional is proven. [ABSTRACT FROM AUTHOR]

Self‐direction has become an important skill in the 21st century. To cultivate learners with a high level of self‐direction, it is necessary to diagnose their self‐directed learning (SDL) ability. This study diagnosed and predicted learners' SDL ability based on their actual SDL behaviours. The study was performed in a self‐directed 3D design class lasting 90 minutes. A total of 193 middle school students participated in the study. The results of the Pearson correlation analysis (p < 0.001) showed that the reported perception of SDL ability was significantly correlated with SDL behaviours. The results of the hierarchical multiple linear regression analysis showed that the SDL behaviours explained 84.9% of the variance in SDL ability (adjusted R2 = 0.849, p < 0.001). Therefore, SDL behaviours had significant predictive effects on the reported perception of SDL ability. Moreover, based on the random forest algorithm, the study built an SDL ability prediction model with high performance (accuracy = 0.83, precision = 0.82, recall = 0.84) using SDL behaviours as features. The study provides evidence for the design of effective strategies to enhance SDL ability and promote SDL behaviours.Practitioner notesWhat is already known about this topicTo cultivate learners with a high level of self‐direction, it is necessary to diagnose their self‐directed learning (SDL) ability.SDL is a combination of internal personal attributes and external autonomous behaviours.Few studies have focused on diagnosing SDL ability based on learners' external SDL behaviours occurring during the learning process.What this paper addsThe reported perception of SDL ability was significantly correlated with SDL behaviours.SDL behaviours had significant predictive effects on the reported perception of SDL ability.Based on the random forest algorithm, the study built an SDL ability prediction model with high performance using SDL behaviours as features.Implications for practice and/or policyThe findings indicate that instructors could design effective strategies to promote SDL behaviours for the purpose of enhancing learners' SDL ability.The method and process of building an SDL ability prediction model might provide a reference for related research on ability prediction with behaviours.

In the education, the use of advanced natural language processing techniques has gained prominence for their potential to revolutionize the teaching and learning experience. Self-learning in English teaching has become increasingly popular due to its flexibility and accessibility. With the advent of digital resources and language learning apps, students can now engage in language acquisition on their own terms. This paper presented a novel framework that combines the power of the Bidirectional Encoder Representations from the Transformers (BERT) model with the Hidden Condition Random Model (HCRM) for the enhancement of English teaching. The primary goal is to provide educators and institutions with a robust tool for evaluating the relevance and quality of teaching materials. The HCRM architecture incorporates sentiment analysis, feature extraction, and classification, making it a comprehensive solution for assessing the suitability of documents in the context of English teaching. The model takes into account the opinions of both students and teachers, ensuring a holistic perspective on the teaching materials' effectiveness. By effectively analyzing sentiments and extracting pertinent features, the HCRM facilitates a nuanced understanding of the potential impact of educational content. This paper's findings suggest that the integration of BERT with HCRM has the potential to greatly enhance English teaching by providing a more accurate, holistic, and data-driven approach to material assessment. The innovative framework presented in this research holds promise for improving the quality and relevance of teaching materials in the field of English instruction. [ABSTRACT FROM AUTHOR]

Being directed against the matters that teaching-learning-based optimization algorithm (TLBO) was prone to plunge into local optimum and slow optimization speed, the paper raised a dynamic adaptive teaching-learning-based optimization algorithm (ITLBO). Firstly, the paper came up with an inertia weight related to the sigmoid function and introduced it into the teacher phase and the student phase to dynamically adjust the population's movement step size, which could suppress the decay of population diversity in the early stage of the algorithm to expand the optimization area, and enhanced the local search ability in the later stage of the algorithm to increase the solutions accuracy. Secondly, in the teacher phase, this paper developed a mechanism of dynamically updating teachers to enhance teachers teaching level, ensuring that students learn from the global optimal solution in a timely manner and improving the convergence speed of the algorithm. Thirdly, in the student phase, this paper put forward a learning approach combining self-study and learning from the most outstanding student to ensure the students comprehensive development, thereby improving the search ability and convergence speed of the algorithm. To validate the effectiveness of ITLBO, adopting 16 standard test functions tested the effectiveness of the inertia weight and the contribution of each operator to the overall algorithm. It conducted the simulation comparative experiment on TLBO, RTLBO, EPGTOA, and ITLBO. A series of test results reveal that ITLBO has more fantastic convergence capability and stability.

Background: The precise effect and the quality of different cases used in dermatology problem-based learning (PBL) curricula are yet unclear. Aim: To prospectively compare the impact of real patients, digital, paper PBL (PPBL) and traditional lecture-based learning (LBL) on academic results and student perceptions. Methods: A total of 120 students were randomly allocated into either real-patients PBL (RPBL) group studied via real-patient cases, digital PBL (DPBL) group studied via digital-form cases, PPBL group studied via paper-form cases, or conventional group who received didactic lectures. Academic results were assessed through review of written examination, objective structured clinical examination and student performance scores. A five-point Likert scale questionnaire was used to evaluate student perceptions. Results: Compared to those receiving lectures only, all PBL participants had better results for written examination, clinical examination and overall performance. Students in RPBL group exhibited better overall performance than those in the other two PBL groups. Real-patient cases were more effective in helping develop students' self-directed learning skills, improving their confidence in future patient encounters and encouraging them to learn more about the discussed condition, compared to digital and paper cases. Conclusion: Both real patient and digital triggers are helpful in improving students' clinical problem-handling skills. However, real patients provide greater benefits to students.

In this paper, a teacher educator discusses her experience of professional learning through self-study. The author found the transition between being a classroom teacher and teacher educator challenging, as has been noted in recent literature. Thus, she decided to embark on a self-study, which was focused on the enhancement of her teaching so that she was not merely transmitting knowledge to her students about the teaching of literacy. Data was gathered using a range of qualitative methods including reflective journals, peer observations, and student focus groups. Themes emerged from the data relating to the importance of activating prior knowledge in learning, the necessity of creating dynamic lecturing spaces and the need to share learning while learning in a university lecture hall. As a self-study, this paper is highly contextual but is intended to provide valuable insights into teaching and learning in higher education. [ABSTRACT FROM AUTHOR]

Historical investigation of novel changes over the ages. It demands observations from different dimensions, confronting one another and sometimes presenting opposite views provided by additional studies. Considering literary analysis about the emergence, structure, component, or features of novels somewhat has diffused the discussion. This paper reviewed the comprehensive theory of Mikhail Mikhailovich Bakhtin regarding the novel, the most celebrated discourse of books. The world merges into an open-ended, multi-voiced, dialogic reality as a novel gives way to distributing entirely incompatible parts among different perspectives of equal importance. Bakhtin opposes monologic speech and acknowledges dialogic speech, which determines social relations where the speaker is embedded. The dialogic discourse offers a radical liberalization of both the self and the concept of culture. The present paper traced the implied dialogism or the social relations within the framework of culture and subculture. Thus language which functions in a novel is not "symptomatic" of "persons," but persons are the bearer of the language, with the "specific set of social and ideological valuations" that entails in a novel.

The paper considers real-time cyberattack detection methods based on an algebraic approach. The author has applied the algebraic matching method, which relies on solving behavioral equations and algebraic modeling. The paper proposes to improve the efficiency of attack detection and prevention by combining a neural network that classifies attacks with an algebraic matching method. This scheme is called a cognitive network, the concept of which was first conceived in 2005. The cognitive network properties, such as double and self-learning, are discussed. The technological line for cyberattack detection using cognitive networks is presented. [ABSTRACT FROM AUTHOR]

Background: Many learners struggle to productively self‐regulate their learning. To support the learners' self‐regulated learning (SRL) and boost their achievement, it is essential to understand the cognitive and metacognitive processes that underlie SRL. To measure these processes, contemporary SRL researchers have largely utilized think aloud or trace data, however, not without challenges. Objectives: In this paper, we present the findings of a study that investigated how concurrent analysis and integration of think aloud and trace data could advance the measurement of SRL and assist in better understanding the mechanisms of SRL processes, especially those details that remain obscured by observing each data channel individually. Methods: We concurrently collected think aloud and trace data generated by 44 university students in a laboratory setting and analysed those data relative to the same timeline. Results: We found that the two data channels could be interchangeably used to measure SRL processes for only 17.18% of all the time segments identified in a learning task. Moreover, SRL processes for around 45% of all the time segments could be detected via either trace data or think aloud data. For another 27.17% of all the time segments, different SRL processes were detected in both data channels. Conclusions: Our results largely suggest that the two data collection methods can be used to complement each other in measuring SRL. In particular, we found that think aloud and trace data could provide different perspectives on SRL. The integration of the two methods further allowed us to reveal a more complex and more comprehensive temporal associations among SRL processes compared to using a single data collection method. In future research, the integrated measurement of SRL can be used to improve the detection of SRL processes and provide a fuller picture of SRL. Lay Description: What is already known about this topic: To support the learners' self‐regulated learning (SRL) and boost their achievement, it is essential to understand the cognitive and metacognitive processes that underlie SRL.To measure SRL processes, contemporary researchers have largely utilized think aloud or trace data, however, not without challenges.Think aloud and trace data should complement each other and, when analysed concurrently, can provide a more valid and fuller picture of SRL than when analysed separately, which is typically the case in the SRL research to date. What this paper adds: We proposed a novel alignment approach to triangulate the measurement of self‐regulated learning (SRL) based on trace and think aloud data.We defined integration rules to integrate the measurement results from trace data and think aloud, which helped to provide a fuller picture of SRL.The integrated results revealed a more complex, complete and comprehensive SRL process map compared to using a single method. Implications for practice and/or policy: First, our results suggest that using a single measurement method can often reveal SRL processes only partially.Second, our findings indicated that the integration of the two measurement methods could not address all their methodological shortcomings and more research is needed towards new integrative approaches that can further reduce the number of misaligned results.In future research, the integrated measurement of SRL can be used to improve the detection of SRL processes and provide a fuller picture of SRL.More specifically, the integrated measurement of SRL can be used in the future to better (1) test the effects of instructional SRL interventions, for example, scaffolding; and (2) evaluate how learners use specific learning tools.

Background: This research is inspired by the challenges encountered in interpreter training, changes in learning needs in the technological era, the educational paradigm shift caused by the COVID‐19 pandemic, the lack of studies on combining virtual reality (VR)_and mobile technologies, and literature gaps in the field of the incorporation of technology in interpreter education. Objectives: This research aims to develop a mobile‐based VR application for bi‐directional English‐Chinese and Chinese‐English interpreting learning named 'Virtual Interpreting Practice' (VIP) based on an interpreting competence model and to investigate its impact on students' self‐rated language and interpreting proficiency levels as well as their declarative knowledge and operative skills as reflected in different interpreting modes (sight and consecutive) and language directions (English‐Chinese and Chinese‐English). The VIP app contains learning resources, including 13 learning modules covering both interpreting modes, practical topics and contexts, video lectures and demonstrations, fully immersive VR and non‐VR practice, glossary lists, source texts, translated texts and an online feedback platform. Methods: Thirty‐one native Chinese‐speaking English as a second/foreign (ESL/EFL) undergraduate students used the app for self‐directed learning. The data were collected by the pre‐study and post‐study questionnaires as well as the pre‐test and post‐test. Results and Conclusions: The results indicate that the use of VIP significantly raised the students' self‐rated language and interpreting proficiency levels as well as their interpreting performance in both modes and language directions. While the students performed better in sight interpreting and Chinese‐English interpreting, they achieved a significantly higher improvement rate in consecutive interpreting and English‐Chinese interpreting. Lay Description: What is already known about this topic: A number of studies have demonstrated the use of virtual reality (VR) provides users with senses of multiple presence, enhances learner engagement and motivation, and facilitates collaborative, situated, immersive and experiential learning that is not often available in traditional learning environments.The increasing availability of VR has created new opportunities in the area of mobile‐assisted language learning (MALL), paving the way for a new research area called VR‐assisted language learning (VRALL).Using VRALL, numerous benefits in various language skills have been identified, such as listening, speaking, writing and vocabulary acquisition. What this paper adds: While blending VR and mobile technologies may play a more significant role in education settings and create more advantages, the impact of this combination for interpreting learning has remained an unexplored area in higher education. This paper has addressed the research gaps in which there is a lack of VR language learning apps that are bilingual, mobile‐based and specifically designed for interpreting practice in highly immersive learning environments.The results indicate that the use of VIP significantly raised the students' self‐rated language and interpreting proficiency levels as well as their interpreting performance in both sight and consecutive interpreting and language directions (English‐Chinese and Chinese‐English).While the students performed better in sight interpreting and Chinese‐English interpreting, they achieved a significantly higher improvement rate in consecutive interpreting and English‐Chinese interpreting. Implications for practice and/or policy: The results have implications for the roles of students and teachers. The app developed in this study shifts the teacher‐led approach to student‐centred learning. While it allows more learning autonomy, its effectiveness may largely depend on students' ability to self‐regulate and engage.It appears that the effectiveness of VRALL depends on a number of individual and contextual factors, e.g. the design and functionality of the apps, availability of the internet connection and smartphones as well as learning needs and motivation.

Summary: Content interest forwarding is a prominent research area in Information Centric Network (ICN). An efficient forwarding strategy can significantly improve data retrieval latency, origin server load, network congestion, and overhead. The state‐of‐the‐art work is either driven by flooding approach trying to minimize the adverse effect of Interest flooding or path‐driven approach trying to minimize the additional cost of maintaining routing information. These approaches are less efficient due to storm issues and excessive overhead. Proposed protocol aims to forward interest to the nearest cache without worrying about FIB construction and with significant improvement in latency and overhead. This paper presents the feasibility of integrating reinforcement learning based Q‐learning strategy for forwarding in ICN. By revising Q‐learning to address the inherent challenges, we introduce Q‐learning based interest packets and data packets forwarding mechanisms, namely, IPQ‐learning and DPQ‐learning. It aims to gain self‐learning through historical events and selects best next node to forward interest. Each node in the network acts as an agent with aim of forwarding packet to best next hop according to the Q value such that content can be fetched within fastest possible route and every action returns to be a learning process, which improves the accuracy of the Q value. The performance investigation of protocol in ndnSIM‐2.0 shows the improvement in a range of 10%–35% for metrics such as data retrieval delay, server hit rate, network overhead, network throughput, and network load. Outcomes are compared by integrating proposed protocol with state‐of‐the‐art caching protocols and also against recent forwarding mechanisms. [ABSTRACT FROM AUTHOR]

Image super-resolution (SR) is a classic problem of image processing. This paper proposes a self-learning interpolation method (SLIM) based on a single image by combining grid feature mapping with binary decision tree, which is not only transparent as the interpolation-based methods, but also achieves comparable performance as the learning-based methods. Firstly, it downsamples the given image I LR to obtain its low–low-resolution image I LLR , which is used to obtain sample data for the self-learning interpolation algorithm for enlarging I LLR to get I LR . Secondly, it provides a structural feature classification method to divide all of the samples into several groups, such that each class of I LLR is mapped to a matrix of coefficients for calculating the values of the pixels of I LR . The image I LR is approximated by executing the decision tree to refine the corresponding mapping matrix. Finally, the resulting high-resolution image I HR is obtained from the given image I LR by using the mapping matrixes. Experimental results show that SLIM achieves more smooth edges and better details on subjective vision than prevailing SR methods, and it is a transparent one but achieves comparable performances on PSNR and SSIM with the learning-based methods, while it outperforms the interpolation-based methods. It means that SLIM is both transparent and efficient and has much better subjective vision than other SR methods. [ABSTRACT FROM AUTHOR]

The study introduces a novel approach to identify potential citation manipulation within academic papers. This method utilizes perturbations of a deep embedding model, integrating Graph-Masked Autoencoders to merge textual information with evidence of graph connectivity. Consequently, it yields a more intricate model of citation distribution. By training a deep network with partial data and reconstructing masked connections, the approach capitalizes on the inherent characteristics of central connections amidst network perturbations. It demonstrates its ability to pinpoint trustworthy citations within the analyzed dataset through comprehensive quantitative evaluations. Additionally, it raises concerns regarding the reliability of specific references, which may be subject to manipulation. [ABSTRACT FROM AUTHOR]

The combination of information technology and machine learning fuels the rapid evolution of today's educational landscape. Revolutions in both fields and a common goal of improving education drive this transformative journey. In a time when resources and information are more readily available than ever, traditional teaching strategies are changing to include digital tools that meet the various needs of students. For a teaching services support system (TSS), this paper proposed a novel machine learning-based model that utilizes the powerful backpropagation (BP) neural network, well known for its machine learning and data analysis capabilities. Increasing the effectiveness of online learning is the primary objective of the TSS, which focuses on contributing to a complete learning environment and promoting self-directed learning. This work closely examines the construction and functionality of the BP neural network within the TSS, contribution visions into input–output mechanisms, activation functions, and weight coefficients. This novel approach can bring concerning a digital age educational revolution by increasing the effectiveness and caliber of online learning, rekindling students' enthusiasm for learning, and making the best use of teaching resources. In addition, the research explores the field of data-mining-based online teaching support services in Open Universities. It clarifies the system's architecture, which includes virtual teaching modules, resource management, and user authentication. Machine learning methods such as adaptive genetic algorithms and BP neural networks optimize the system's architecture. Experimental results achieved remarkable BP neural network accuracy and stability, significantly enhancing instructional quality and student engagement. The results show an impressive 83.4% accuracy, outperforming traditional methods such as SVM, KNN, DT, RF, and XGBoost. This demonstrates how learning outcomes and productivity can be enhanced by incorporating machine learning into education. [ABSTRACT FROM AUTHOR]

Teaching–learning-based optimization (TLBO) algorithm is an excellent human-inspired optimization technique. This paper proposes an innovative improved version of TLBO—collectivism teaching–learning-based optimization (CTLBO) algorithm. This algorithm imitates group and individual behaviours in the reality of teaching and learning, applies group-individual multi-mode cooperation strategies to form new search mechanism. The CTLBO contains three phases, i.e. preparation phase, teaching and learning phases. In the preparation phase, there are two operators, i.e. teacher self-learning and teacher-learner interaction operators. In the teaching phase, class teaching and performance-based group teaching operators are implied. In the learning phase, neighbour learning, student self-learning and team-learning strategies are mixed together to form three operators. Two sets of experiments are conducted to test the performance of CTLBO. The first set of experiments validates the improvement effect of CTLBO by comparing it with the original TLBO and other authors' improved versions of TLBO. The second set of experiments illustrates the advantage of CTLBO by comparing it with other 17 meta-heuristic algorithms in solving 30 general benchmark functions and 15 CEC2015 test suit functions. The results of experiments show that CTLBO algorithm has significant improvement effect compared with TLBO. It is the most effective one amongst the improved versions of TLBO selected for comparison, and outperforms all other 17 meta-heuristic algorithms. The algorithm can significantly improve the convergence ability and the accuracy in solving different-scale complex optimization models. [ABSTRACT FROM AUTHOR]

Background: This paper analyzes a remembered shared experience of cocurricular designing and coteaching an experiential learning pilot project in a university study abroad program (SAP) that emphasized social justice. Purpose: We look back because the pilot program is a significant demonstration of what complexities can arise when feminist educators bring their own politics and pedagogies to experiential learning and study abroad education contexts; we understand this as valuable because "experience" broadly is complex. Memory is crucial to feminist educators because it indicates the development of care, ethics, pedagogy, politics, and priorities, and so, we ask: what pedagogical insights can be gained through revisiting our enmeshed personal/professional memories of cocurricular designing and coteaching an experiential learning series for study abroad students? Methodology: We use self-study and memory work to analyze memory objects (curriculum materials) and narratives (of teaching) to explore this pedagogical work and highlight generative tensions that emerged while employing a critical feminist approach to work not initially conceptualized with this framing. Findings: We uncovered three key tensions: personal, community, and racial that troubled emergent issues related to difference, discourse, and positionality. Implications: This project offers pedagogical insights into how oppression and inequality may enter experiential learning and study abroad spaces. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate the self-study methods used by pilots while grounded and their perception of competence decline and confidence upon their return to flying. Background: Previously, long absences from flying were managed on a case-by-case basis. Thousands of pilots returning to flying as the pandemic eases have burdened airline training systems. Limited research has been conducted on the decline in skills of airline pilots while operationally absent from the cockpit. Few studies have considered this topic in the context of a pandemic. Method: A questionnaire study was conducted with 234 airline pilots who were grounded during the COVID-19 pandemic. Results: Uncertainty regarding sudden and indefinite periods of grounding made it challenging to maintain motivation to self-study. This matter was aggravated by the additional financial and personal stress caused by the state of the airline industry and the outcomes of the pandemic. The participants anticipated a decline in manual flying skills as the worst outcome after being absent from the flight deck. However, these pilots proved quick to recover these skills when they resumed flying. It took significantly more time for pilots to regain proficiency in applying knowledge, procedures and compliance with regulations, situation awareness and workload management. Conclusion: The study proposes recommendations for pilots and airlines to harness essential self-study practices in competency areas identified to have significantly declined. Application: The outcome of this paper guides airlines, pilots and regulators in better understanding how grounded pilots observe skill decline in a broader range of competencies.

This paper aims to offer a new perspective on role modelling by examining adolescents' own efforts to lead a morally virtuous life. While traditional approaches to moral education emphasize the importance of teachers as role models, this study proposes a shift in focus towards adolescents' own role models. Drawing on the philosophical concept of moral self-cultivation and psychological insights on identity development and social cognitive learning, it is argued that adolescents have the ability to cultivate their moral character by emulating others. However, empirical evidence suggests that adolescents often do not perceive teachers as their role models. Consequently, moral educational theories are advised to demand less of teachers as role models. Teachers could invest more time in understanding students' personal role models and encourage them to compare these role models with their own behavior. By acknowledging and addressing students' role models, teachers can facilitate the moral self-cultivation of adolescents. [ABSTRACT FROM AUTHOR]
