The purpose of this exploratory study was to investigate early childhood preservice teachers' perceptions of computer science and gender stereotypes in computer science, and perceptions of coding in early childhood education. Quantitative and qualitative data were collected from early childhood preservice teachers enrolled in a teaching methods course at a large southeastern university in the U.S. Findings showed that participants had misconceptions about what CS is and what computer scientists do. They were also neutral about coding and its integration in early childhood education. Both qualitative and quantitative data supported that the participants did not hold gender stereotypes in CS.

Lifelong learning in a globalized world: The need for critical social theory in adult and lifelong education

引用

INTERNATIONAL JOURNAL OF LIFELONG EDUCATION 2022年第1期41卷 107-121页

作者： Gouthro, Patricia A. Mt St Vincent Univ Grad Studies Lifelong Learning Program Fac Educ Halifax NS Canada

This paper traces the evolution of discourses around the role of critical social theory in the field of lifelong education that have played out in the pages of the International Journal of Lifelong Education and elsewhere in the field, beginning with early critical theoretical discourses, a consideration of the impact of some key theorists and topics in the field, and then exploring the impact of feminist discourses and postmodernism and increasing interest in issues pertaining to identity. It raises questions about the future of adult education, given the rise of neoliberal values that threaten to undermine the historically critical social purpose focus of adult education. Due to neoliberal influences in academe, scholars may be concentrating on the dissemination of findings from externally funded research studies rather than focusing on the development of theoretical perspectives that provide an integral foundation for the field of lifelong education. The advancement of theory helps the field of adult education to explore global issues challenges that need to be addressed and develop analytical perspectives that address diversity and inclusion issues. Theory offers a framework to explore and inform policy development, to analyse research, and to develop democratic pedagogical practices for adult learners.

Renewable energy is considered an innovative solution for today's challenges of energy production and its related issues. One of the promising and developing types of renewable energy is wind energy due to its reliability. In the past decades, researchers have focused their efforts on developing wind energy technology day after day. Wind energy conversion systems (WECS) should operate at the maximum power point for maximum utilization. Various studies have addressed different algorithms to do so. However, selecting and nominating a specific algorithm for a specific application in a specific location requires proficiency and a deep understanding of both (WECS) and algorithms, as each algorithm has its advantages and limitations. Considering the importance of evaluating the maximum power point tracking (MPPT) algorithms, few attempts in the literature have reviewed those different algorithms and compared them. In this paper, various MPPT algorithms are investigated and criticized. The algorithms are categorized according to direct and indirect power control and measurement, as well as those using artificial intelligence and soft computing techniques. Merits and demerits are addressed through nominated parameters such as speed of wind measurements, complexity, memory requirement, training, efficiency, and response time.

Plastic pollution is a pressing global issue, impacting both the environment and human health. The urgency of this challenge is underscored by the ongoing United Nations negotiations for a legally binding instrument on plastic pollution. Given the complexities of the plastic waste stream and recycling processes, exploring innovative solutions is crucial. Advanced recycling has been offered as a potential solution to combat the influx of plastic waste, and we examined its connections with post-use plastic feedstock and human health, providing a neutral overview without endorsing any specific solutions. The debate on classifying these technologies as recycling highlights the need for universal definitions and transparency in waste management. Using the United States as a case study, different approaches to advanced recycling, their implementation status, and related policy gaps are compared. Simplified plastic formulations, transparent reporting on the environmental footprint of advanced recycling, and increased research investments may be needed to pave the way for a more sustainable future in plastic waste management. Insights obtained from this review will help non-specialists, particularly policymakers, and relevant industry sectors understand the landscape of advanced recycling within the United States.

The treatment was performed three times a week for 4 weeks, totaling 12 sessions. PFM function was assessed using the PERFECT scheme (P = power, E = endurance, R = repetitions, F = rapid contractions, ECT = each timed contraction) and the perineometer (cmH2O). Sexual function was assessed by The Female Sexual Function Index, and QoL by the SF-36 questionnaire. These assessments were performed before and after the 12nd treatment session and after 30-day *** was a significant increase (p = 0.037) in the power of G2 compared to G1;repetitions and fast contraction increased in the G1 group, and the resistance increased in both groups, however, without statistical difference between the groups. ECT increased in the G1 group (p = 0.0).ConclusionActive tDCS combined with PFMT did not potentiate the effect of the PFMT to increase the PFM function, QoL, and sexual function in healthy women. However, adjunctive tDCS to PFMT improved the time of contractions, maintaining it during follow-up.

Under the increasingly complex and interconnected world we live in, data has become extremely valuable. Nevertheless, exploring even a simple database is not a trivial task, as it requires technical knowledge which many new and non-technical data users do not have. This task includes writing database queries to retrieve data, uncover insights, and exploit patterns. Furthermore, in large volumes of data, finding valuable data that matches a certain user’s purpose requirement is challenging, especially under restrictive time constraints. Typically, this task is manual, ad-hoc, and time-consuming. To address these challenges, researches have proposed tools to support data exploration tasks, especially by means of View Recommendation. However, current recommendation approaches require enumerating all candidate views that can be defined over an input database. In this work, we introduce a novel view recommendation method that leverages a human-in-the-loop approach to create, evaluate, and tailor views to match user intent. Our experimental evaluation on real-world data demonstrates that our approach suitably recommends views that capture multiple perspectives on the data at hand. © 2023 IEEE.

Badminton is a very popular subject in Physical Education (PE). Many students enroll badminton courses in every semester which pose a tremendous teaching load to the instructors. The one-on-one guiding/feedback time provided by the instructor to each student is also greatly reduced. To overcome this challenge, some studies have tried to adopt pose recognition technique in teaching badminton. However, the lack of mobility and recognition accuracy problems hinder its applicability. To address this issue, a new pose recognition technique, OpenPose, was employed to develop a real-time pose recognition badminton teaching APP in this study. The APP was then installed on a mobile device to enhance badminton smash skill learning performance. The scores distribution of the experimental group shows majority of students achieved satisfactory performance, this implies the badminton teaching APP is helpful to all students no matter what their initial skill levels are. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

The relationship between phonological processing and arithmetic in children with learning disabilities

Phonological processing skills have not only been shown to be important for reading skills, but also for arithmetic skills. Specifically, previous research in typically developing children has suggested that phonological processing skills may be more closely related to arithmetic problems that are solved through fact retrieval (e.g., remembering the solution from memory) than procedural computation (e.g., counting). However, the relationship between phonological processing and arithmetic in children with learning disabilities (LDs) has not been investigated. Yet, understanding these relationships in children with LDs is especially important because it can help elucidate the cognitive underpinnings of math difficulties, explain why reading and math disabilities frequently co-occur, and provide information on which cognitive skills to target for interventions. In 63 children with LDs, we examined the relationship between different phonological processing skills (phonemic awareness, phonological memory, and rapid serial naming) and arithmetic. We distinguished between arithmetic problems that tend to be solved with fact retrieval versus procedural computation to determine whether phonological processing skills are differentially related to these two arithmetic processes. We found that phonemic awareness, but not phonological memory or rapid serial naming, was related to arithmetic fact retrieval. We also found no association between any phonological processing skills and procedural computation. These results converge with prior research in typically developing children and suggest that phonemic awareness is also related to arithmetic fact retrieval in children with LD. These results raise the possibility that phonemic awareness training might improve both reading and arithmetic fact retrieval skills. Research Highlights Relationships between phonological processing and various arithmetic skills were investigated in children with learning disabilities (LDs) for the firs

The patient's infusion fluid will only be changed if the nurse changes it or based on information from the patient's family. The research method used in terms of fluid volume utilizes the function of the Arduino microcontroller as the brain, the load cell sensor as an infusion fluid weight detector connected to the IoT, fuzzy logic calculations on the infusion volume weight measuring device in line with real-time decision-making when reading gram weight changes with sensors, and the system development method using a prototype model. The test results of three infusion bottles containing mineral water with a liquid volume of 500 ml and a load cell sensor as an infusion weight detector can be accepted by the Arduino Wemos D1 as a load cell sensor processing component. The infusion liquid weight data is uploaded to the MySQL database, and a notification is sent and displayed on the smartphone when the infusion volume reaches 12% of its weight. The results of this study indicate that the design of tools connected to applications on smartphones can work well and facilitate the process of monitoring infusions for patients in real-time © 2024 IEEE.
