This study’s urgency is determined by absence of serious researches in the usage area of «flipped» learning model (FLM) applied to engineering geometry and computer graphics (EGCG); by absence of scientifically-based, tested and implemented programs and learning materials for EGCG FLM; as well as by the need for development of new modern tools to support classroom work and forms of students’ individual work. The purpose of this study is to examine the current state of knowledge and practice of existing EGCG courses, using the FLM concept as the main pedagogical strategy. Research methods are pedagogical experiment, expert assessment, cluster analysis. Problem state: since 2012 the FLM approach has gained popularity not only in schools but also in engineering universities. FLM presents opportunities for solutions of complex pedagogic problems in engineering education, but creates some difficulties in model implementation preparing. Most of based on the FLM researches in the area of engineering education have been conducted on the basis of short-term studies, and on feedback from professors and students and their reviews. Theoretical and practical contribution of materials: this paper represents a synthesis of qualitative and quantitative researches on engineering courses using the FLM. The study has demonstrated that the issues of EGCG FLM have not been investigated in the scientific and methodological literature. Has been identified students relation to the FLM, as well as to the role of learning materials and professor’s personality in the FLM. Advantages and disadvantages of the FLM have been revealed, and recommendations on students training have been presented. Study significance: the study has proved the absence of scientifically-based, tested and implemented programs and learning materials for students learning on EGCG using FLM. To create reasonable theoretical bases for pedagogy in the area of EGCG FLM, as well as corresponding evaluation methods it is necessary to conduct further scientific researches examining various aspects related to practical implementation of long-term programs and learning materials. This paper’s materials can be useful for lecturers of technical universities.

The early and long-term development of promising young athletes is a decisive factor in being internationally competitive in top-level sports. Among the multitude of talent criteria suggested in the literature, motivation plays a prominent role in the area of psychological characteristics. It is recognised in practice and research as a relevant criterion for performance development across all sports. This article provides an overview of the current state of talent research in the field of motivation. First, the most common theories of motivation in competitive sports are described, then different measurement methods and their advantages and disadvantages as well as the predictive value of motivation for athletic performance are discussed. Finally, implications for practice are suggested. It can be summarised that motivation in sport is conceptualised and operationalised in different ways and that the decision for the right measurement instrument depends on the goal of the assessment. To get a comprehensive picture of an athlete’s motivational status, it is useful to assess several aspects of motivation through different methods.

AbstractA problem for a circular economy, embedded in its policies, tools, technologies and models, is that it is driven by the interests and needs of producers, rather than customers and users. This opinion paper focuses on an alternative form of governance—agreements, which thanks to their bargaining approach brings actors from across the value chain into the policy process. The purpose of this opinion paper is to uncover and analyse the potential of such agreements for a circular economy. Circular agreements aim at increasing the circulation of materials and are an emerging form of political governance within the EU. These agreements have different names, involve different actors and govern in different ways. However, circular agreements seem to work when other types of regulations fail to establish circulation. These agreements bring actors together and offer a platform for negotiating how advantages and disadvantages can be redistributed between actors in a way that is more suitable for a circular economy. However, circular agreements are dependent on other policy instruments to work and can generate a free-rider problem with uninvolved actors. The agreements may also become too detailed and long term, which leads to problem shifting and lock-ins, respectively.

This chapter discusses the topic of standards for Virtual Worlds with emphasis on their usability as a stable and reliable basis for long-term investments into 3D-E-Commerce. The text explains why standards are important for the success of Virtual Worlds as well as the business in these shared online 3D environments, and what the relevant criteria are to decide for the right technology and/or provider. Although sometimes in the shadow of popular proprietary platforms there are already many different candidates for a Virtual World standard, currently in different states of development. By choosing a 3D platform, E-Commerce providers will decide about their business potential and at the same time strengthen one or another standard in the current technical competition phase. So it is important to get an overview about the current approaches, their advantages and disadvantages as well as the tendencies for the future developments. In this chapter the reader will be sensitized for the issues of standardization, compatibility and interoperability of Virtual Worlds for successful E-Commerce applications. An overview about the current approaches supports the orientation and decision for the different technologies. Some concrete XML-based code examples realized in the international ISO standard for interactive 3D-Graphics X3D demonstrates the practical deployment of highly compatible concepts. An outlook to the further integration of interactive 3D graphics into the Next Generation Web respectively the 3D Internet completes the overview.

The article considers the current state of engineering education in Europe in general and in Russia in particular in the light of the need to meet employers’ requirement to graduates, and the role of practice-oriented learning technologies in this process. The demand for graduates on the labour market and their competitiveness is seen as the main indicator of the education system ability to react and adapt to the market demands. Thus the employers’ requirements should be one of the most important drivers for the learning process. And the practice-oriented learning technologies are given as the most effective answer to these needs as they imply involvement of the employer and solution of real-world tasks and problems.

Modern realistic computer graphics are based on light transport simulation. In this case, one of the main and difficult to calculate tasks is to calculate the global illumination, i.e. distribution of light in a virtual scene, taking into account multiple reflections and scattering of light and all kinds of its interaction with objects in the scene. Hundreds of publications and describing dozens of methods are devoted to this problem. In this state-of-the-art review, we would like not only to list and briefly describe these methods, but also to give some “map” of existing works, which will allow the reader to navigate, understand their advantages and disadvantages, and, thereby, choose a right method for themselves. Particular attention is paid to such characteristics of the methods as robustness and universality in relation to the used mathematical models, the transparency of the method verification, the possibility of efficient implementation on the GPU, as well as restrictions imposed on the scene or illumination phenomena. In contrast to the existing survey papers, not only the efficiency of the methods is analyzed, but also their limitations and the complexity of software implementation. In addition, we provide the results of our own numerical experiments with various methods that serve as illustrations for the conclusions.

Abstract Blood transfusion remains an important therapeutic intervention in patients with sickle cell disease (SCD), aiming to both increase the oxygen carrying capacity of blood and to reduce the complications of vaso-occlusion. Simple, manual exchange and automated exchange can be effective in reducing the acute and chronic complications of SCD, and the advantages and disadvantages of each methodology mean they all have a role in different situations. Evidence for the role of emergency transfusion in the management of the acute complications of SCD, including acute pain and acute chest syndrome, comes from observational data. Several important randomized controlled trials have shown the efficacy of transfusion in primary and secondary stroke prevention in patients with SCD but, outside these areas, clinical practice lacks a clear evidence base. Evidence for the role of long-term transfusion in the prevention of the non-neurologic chronic complications of SCD comes from analysis of secondary outcomes of these randomized trials and from observational data. In view of the paucity of data, the risks and benefits of transfusion should be fully discussed with patients/families before a long-term transfusion program is commenced. Evidence is only available for the role of preoperative transfusion or for prophylactic transfusion through pregnancy in certain situations, and the role of transfusions outside these situations is discussed. Questions about when and how to transfuse in SCD remain and will need further randomized trials to provide answers.

Purpose – This paper aims to, through an analysis of the current literature, explore the current state of the library e-publishing community and its approach to preservation. Libraries are increasingly proposing publishing services as part of their work with their communities, and recently, there has been a pronounced interest in providing electronic publishing (e-publishing) services. The library e-publishing community, however, has not systematically studied the need for the long-term preservation of the digital content they help create. Design/methodology/approach – Through a reflective analysis of the literature, this paper explores the context and the evolution of e-publishing as a trend that aligns with public library missions; in doing so, it also explores implications for digital preservation in the context of these new services and identifies gaps in the literature. Findings – Digital preservation is an important and worthwhile activity for library e-publishers; preservation of community-based author content cannot, however, be an afterthought and should be planned from the beginning. Future study should take into consideration the needs and expectations of community-based authors. Existing digital preservation guidelines also provide a point of reference for the community and researchers. Originality/value – This paper addresses the understudied area of the importance of digital preservation to library e-publishing. In doing so, it also investigates the role of the library in supporting community-based authors when e-publishing through the library.

And Function

This chapter unpacks the concepts of trust and legitimacy as they pertain to sovereign funds in the global political economy. Its argument is divided into three parts. First, the importance of trust in finance and geopolitics, and the critical role of transparency, and how this relates to sovereign funds. Second, the legitimacy of sovereign funds at home and abroad in general with particular reference to how the regulatory regime surrounding public institutional investors in developed democracies is emulated in the Santiago Principles, and why it is significant for understanding the legitimacy of sovereign funds. Third, the current state of trust and legitimacy for sovereign funds is evaluated, with an explanation of why the continued opacity of some sovereign funds has not reduced trustworthiness. The chapter concludes on a speculative note, suggesting that the expected institutional form and function of sovereign funds may be at odds with the long-term interests of their state-sponsors.

PurposeThis study examined predictors of cumulative grade point average (GPA) from entrance scores and successive performance during students' academic work in university engineering programs.Design/methodology/approachScores from high school coursework, the General Ability Test and the Achievement Test were examined to determine if these factors and annual successive GPAs were predictors of long-term GPA. The sample consisted of 2,031 students registered in university engineering programs during the 2013–2019 period.FindingsCorrelations were significant between entrance scores and the preparatory year GPA but not with cumulative GPA. Also, correlations were significant between year-1 GPA to year-3 GPA and the graduation GPA. Adjacent year GPA is the better predictor of later GPA. More importantly, GPA at the time of graduation is well predicted by GPAs throughout years of study within engineering programs after controlling for entrance scores. Girls outperform boys in their entrance scores and GPAs. Hence, girls are likely to obtain higher cumulative GPAs.Research limitations/implicationsThe implications of the study findings could help university faculty and administrators to understand the role of current entrance scores in predicting academic achievement of engineering students. In addition, the results could serve as a foundation to review weights of entrance scores for future developments and revisions. The findings of the study are limited to admission data for engineering students during the 2013–2019 period. Other disciplines may show a different pattern of relationships among the studied variables.Practical implicationsThe study findings have useful practical implications for admitting and monitoring student progress at engineering education programs. Results may help program curriculum development specialists and committees in designing admission criteria.Social implicationsAdministrators and faculty members are advised to consider entrance scores when providing counseling and monitoring throughout students' program-year progress. More attention should be devoted to university performance when interest is focused on later or graduation CGPA, with less emphasis on entrance scores.Originality/valueThe existed previous studies explored factors that influence the student performance in engineering programs. This study documents the role of admission criteria and successive GPAs in predicting the student graduation CGPA in engineering programs. Relationships between factors are crucial for engineering program revisions and policymaking.
