Research Trends in Flipped Classroom Empirical Evidence from 2017 to 2018: A Content Analysis

Purpose – This paper aims to analyze the trends and contents of flipped classroom research based on 48 selected empirical articles published during 2017 and 2018. Design/methodology/approach – The inductive content analysis was used as a methodology to investigate the content of flipped classroom research, including subject-specific areas, methodological approaches, technology tools or platforms, the most frequently used trending searches, countries of research, positive impacts and challenges. Findings – The results of the analysis were interpreted using descriptive analysis, percentages and frequencies. This analysis found that various subjects were implemented in flipped classroom learning, and some technological tools were also used to enhance teaching and learning. Analysis of the impact revealed that the flipped classroom yielded positive learning outcomes on students’ learning activities such as learning motivation and engagement, social interaction and self-directed learning skills. Meanwhile, the most significant challenges encountered by the instructor were the lack of students’ motivation to watch pre-recorded video lectures or to study the contents outside of the class time. Originality/value – The findings suggest that the flipped classroom concept might be effective in promoting twenty-first-century learning skills and developing the technology and information literacy competency based on national standards

MELDing Multiple Granularities of Parallelism

We are developing an experimental programming language, MELD, that supports a range of concurrent styles by supporting multiple programming paradigms at multiple levels of granularity. MELD integrates three granularities of parallelism: macro dataflow among statements within a method or among methods for fine grain concurrency, synchronous or asynchronous message passing among local or remote objects for medium grain concurrency, and transactions for large grain concurrency among users

PyFR: An Open Source Framework for Solving Advection-Diffusion Type Problems on Streaming Architectures using the Flux Reconstruction Approach

High-order numerical methods for unstructured grids combine the superior accuracy of high-order spectral or finite difference methods with the geometric flexibility of low-order finite volume or finite element schemes. The Flux Reconstruction (FR) approach unifies various high-order schemes for unstructured grids within a single framework. Additionally, the FR approach exhibits a significant degree of element locality, and is thus able to run efficiently on modern streaming architectures, such as Graphical Processing Units (GPUs). The aforementioned properties of FR mean it offers a promising route to performing affordable, and hence industrially relevant, scale-resolving simulations of hitherto intractable unsteady flows within the vicinity of real-world engineering geometries. In this paper we present PyFR, an open-source Python based framework for solving advection-diffusion type problems on streaming architectures using the FR approach. The framework is designed to solve a range of governing systems on mixed unstructured grids containing various element types. It is also designed to target a range of hardware platforms via use of an in-built domain specific language based on the Mako templating engine. The current release of PyFR is able to solve the compressible Euler and Navier-Stokes equations on grids of quadrilateral and triangular elements in two dimensions, and hexahedral elements in three dimensions, targeting clusters of CPUs, and NVIDIA GPUs. Results are presented for various benchmark flow problems, single-node performance is discussed, and scalability of the code is demonstrated on up to 104 NVIDIA M2090 GPUs. The software is freely available under a 3-Clause New Style BSD license (see www.pyfr.org)

Two sides of the same coin: accessibility practices and neurodivergent users' experience of extended reality

Purpose: This paper explores the accessibility barriers faced by neurodivergent individuals regarding the use of Extended Reality (XR) technologies and the difficulties faced by developers in creating neurodivergent inclusive XR experiences. Design/methodology/approach: The authors carried out a survey with neurodivergent participants, and a series of semi-structured interviews with neurodivergent adults and XR developers. Findings: Neurodivergent individuals experience sensory overload when using XR technologies; these negative experiences are exacerbated by excessive multisensory stimulation. Allowing for the customization of sensory settings was seen as the only way to potentially limit negative experiences. The authors found that XR developers lacked awareness of accessibility requirements and struggled to integrate them in current software development practices. Social implications: Accessibility understanding regarding neurodivergence is increasingly available and the time has come to bring computing and information services within the reach of all neurodivergent individuals. The power in the design of XR, which is crucial, is decentralized from neurotypical XR developing practices to avoid artificial barriers that decrease the quality of life. Originality/value: There is a lack of studies exploring how neurodivergent individuals experience XR considering their different sensory processing patterns. There is also no research exploring XR developers' awareness of accessibility needs of neurodivergent individuals. This paper presents an account of the challenges faced by neurodivergent XR users, the difficulties faced by XR developers to integrate neurodivergent accessibility requirements, and proposes specific strategies to overcome challenges

The Information and Learning Commons: A Selective Guide to Sources

Purpose: This bibliography aims to give citations and annotations for a core selection of sources on the information and learning commons trend in academic libraries. Design/methodology/approach: Articles, books, and web sites relevant to this topic were found in the Library, Information Science & Technologoy Abstracts database; Library Literature Index; WorldCat; and on the internet. Sources were chosen that contribute to an overview of the concepts or cover pratical considerations in implementation. Findings: Libraries are developing best practices as they experiment with learner-centered service models, but they apply these best practices differently according to their unique needs. Early implementations focus on technology and access, while later implementations focus on more collaborations surrounding learner-centered pedagogies. Research limitations/implications: This bibliography selects from English language books, web sites, and peer reviewed journals about US, British, Canadian, and Ociania academic libraries, large and small. Originality/value: This survey of the literature will help librarians and administrators understand the theoretical trends and collaboration that influence how libraries can change service, space, and technology to meet emerging needs

Sport, Gender and Development : Intersections, Innovations and Future Trajectories

The ebook edition of this title is Open Access, thanks to Knowledge Unlatched funding, and freely available to read online. In a context where striving for gender equity in relation to achieving the UN Sustainable Development Goals seems more pressing than ever before, Sport, Gender and Development: Intersections, Innovations and Future Trajectories bring together an exploration of sport feminisms to offer new approaches to research on Sport for Development and Peace (SDP) in global and local contexts. Including postcolonial and decolonial feminist lenses by drawing upon fieldwork with organizations and individuals in Afghanistan, Uganda, Nicaragua, and India, Sport, Gender and Development reveals the complexities of development and gender discourses and how they operate on and through researchers, practitioners, and participants\u27 bodies. Delving into a thoughtful engagement with the (dis)connections and comparisons across these diverging contexts, this book offers a critically reflexive account of what is transpiring in the transnational sport, gender, and development field, while remaining sensitive to the importance of community context and local iterations. Taking up emerging and contemporary feminist issues in sport-related international development, this book advances empirical, conceptual, and theoretical developments in the sport, gender, and development.

Logic-based Technologies for Multi-agent Systems: A Systematic Literature Review

Precisely when the success of artificial intelligence (AI) sub-symbolic techniques makes them be identified with the whole AI by many non-computerscientists and non-technical media, symbolic approaches are getting more and more attention as those that could make AI amenable to human understanding. Given the recurring cycles in the AI history, we expect that a revamp of technologies often tagged as “classical AI” – in particular, logic-based ones will take place in the next few years. On the other hand, agents and multi-agent systems (MAS) have been at the core of the design of intelligent systems since their very beginning, and their long-term connection with logic-based technologies, which characterised their early days, might open new ways to engineer explainable intelligent systems. This is why understanding the current status of logic-based technologies for MAS is nowadays of paramount importance. Accordingly, this paper aims at providing a comprehensive view of those technologies by making them the subject of a systematic literature review (SLR). The resulting technologies are discussed and evaluated from two different perspectives: the MAS and the logic-based ones

Space mission risk, sustainability and supply chain: review, multi-objective optimization model and practical approach

This paper investigates the convergence of risk, sustainability, and supply chain in space missions, including a review of fundamental concepts, the introduction of a multi-objective conceptual optimization model, and the presentation of a practical approach. Risks associated with space missions include technical, human, launch, space environment, mission design, budgetary, and political risks. Sustainability considerations must be incorporated into mission planning and execution to ensure the long-term viability of space exploration. The study emphasizes the importance of considering environmental sustainability, resource use, ethical concerns, long-term planning, international collaboration, and public outreach in space missions. It emphasizes the significance of reducing negative environmental consequences, increasing resource use efficiency, and making responsible and ethical actions. The paper offers a multi-objective optimization conceptual model that may be used to evaluate and choose sustainable space mission tactics. This approach considers a variety of elements, including environmental effects, resource utilization, mission cost, and advantages for society. It provides a systematic decision-making approach that examines trade-offs between different criteria and identifies optimal conceptual model solutions that balance risk, sustainability, and supply chain objectives. A practical approach is also offered to demonstrate the use of the multi-criteria optimization conceptual model in a space mission scenario. The practical approach demonstrates how the model can aid in the development of mission strategies that minimize risks, maximize resource consumption, and fit with sustainability goals. Overall, this paper delivers a multi-criteria optimization conceptual model and provides a space mission planning practical approach, as well as an overview of the interaction between risk, sustainability, and supply chain in space mission organization, planning, and execution.This research was partially supported by the AGH University of Science and Technology, Kraków, Poland (16.16.200.396) and the financial aid of the Polish Ministry of Science and Higher Education (MNISW) grants (N N519 405934; 6459/B/T02/2011/40) and the Polish National Science Centre (NCN) research grant (DEC-2013/11/B/ST8/04458).

Models of higher-order, type-safe, distributed computation over autonomous persistent object stores

A remote procedure call (RPC) mechanism permits the calling of procedures in another address space. RPC is a simple but highly effective mechanism for interprocess communication and enjoys nowadays a great popularity as a tool for building distributed applications. This popularity is partly a result of their overall simplicity but also partly a consequence of more than 20 years of research in transpaxent distribution that have failed to deliver systems that meet the expectations of real-world application programmers. During the same 20 years, persistent systems have proved their suitability for building complex database applications by seamlessly integrating features traditionally found in database management systems into the programming language itself. Some research. effort has been invested on distributed persistent systems, but the outcomes commonly suffer from the same problems found with transparent distribution. In this thesis I claim that a higher-order persistent RPC is useful for building distributed persistent applications. The proposed mechanism is: realistic in the sense that it uses current technology and tolerates partial failures; understandable by application programmers; and general to support the development of many classes of distributed persistent applications. In order to demonstrate the validity of these claims, I propose and have implemented three models for distributed higher-order computation over autonomous persistent stores. Each model has successively exposed new problems which have then been overcome by the next model. Together, the three models provide a general yet simple higher-order persistent RPC that is able to operate in realistic environments with partial failures. The real strength of this thesis is the demonstration of realism and simplicity. A higherorder persistent RPC was not only implemented but also used by programmers without experience of programming distributed applications. Furthermore, a distributed persistent application has been built using these models which would not have been feasible with a traditional (non-persistent) programming language
