Geometric intuition is one of the core concepts introduced by the new mathematical curriculum standards. It aims to use intuition and intuitive materials to deepen the understanding of mathematics in mathematical cognition activities. It does not only play a role in the learning of “graphics and geometry,’ but its’ irreplaceable role also involves the whole process of mathematics education. Therefore, if teachers can skillfully use geometric intuition in the teaching process, classroom efficiency will be greatly improved.

Jumping, climbing and suspensory locomotion are specialized locomotor mechanisms used on land and in the air. Jumping is used for rapid launches from substrates. Climbing and suspensory movements enable locomotion up, under and through vertically-structured habitats, such as forests. Elastic energy storage is particularly important for jumping and catapult systems and we address the core concepts of power amplification that are exemplified in nature’s extreme jumpers. We examine the diverse mechanisms of attachment that characterize animals that can grasp and adhere to a diversity of structures. We conclude the chapter by examining the integration of biological capabilities with engineering innovations in these systems.

This work studies the jitter buffer management algorithm for Voice over IP in WebRTC. In particular, it details the core concepts of WebRTC’s jitter buffer management. Furthermore, it investigates how jitter buffer management algorithm behaves under network conditions with packet bursts. It also proposes an approach, different from the default WebRTC algorithm, to avoid distortions that occur under such network conditions. Under packet bursts, when the packet buffer becomes full, the WebRTC jitter buffer algorithm may discard all the packets in the buffer to make room for incoming packets. The proposed approach offers a novel strategy to minimize the number of packets discarded in the presence of packet bursts. Therefore, voice quality as perceived by the user is improved. ITU-T Rec. P.863, which also confirms the improvement, is employed to objectively evaluate the listening quality.

This commentary highlights the contribution that careful and systematic analyses of curriculum or content standards can make to questions and issues important in the mathematics education field. We note the increased role that curriculum standards have played as part of a standards-based education reform strategy. We also review different methods used by researchers to compare and analyze the Common Core State Standards for Mathematics, each method designed for a particular purpose. Finally, we call upon mathematics education researchers to engage in careful analysis of curriculum standards and to share their findings in ways that can inform public debate as well as support education professionals in improving student learning opportunities.

Abstract This article analyzes the relationship between the core concepts of disability policy and the three generations of inclusive practices. Specifically, we review the three generations of inclusive practice, highlighting the core concepts that have been most strongly emphasized during each generation of inclusive practices. Because we are early in the third generation of inclusive practices, we conclude by examining how the core concepts can guide and direct third generation inclusive practices and how future research, policy, and practice can actualize the aspirational values of all of the core concepts to enable desired outcomes.

The resent movement of Systemic Design seeks for new synergies between Design and Systems. While the usefulness of systems approaches in design has been fairly obvious, this paper argues that many core concepts in design are beneficial in systems thinking. This seems reasonable when it comes to the concept of Design Thinking. However, as this paper argues, the more practical core concepts of design are equally important. Designerly skills have been regarded as belonging mainly in the realm of traditional commercial design, whereas design thinking has been regarded as useful in strategic management settings. This paper argues against the idea of separating design thinking from design action. The skills and competences of design, such as the composition of the shape and form that are obvious in product design, are central to Systems Oriented Design (SOD). SOD is a version in the emerging pluralistic field of Systemic Design. The Systemic Design movement should recognise the core values of design and integrate them in systems thinking. This integration would contribute to innovation in both Systemic Design and systems thinking. Among the core competences of design discussed in the paper are composition, choreography, orchestration, the notion of the Gesamtkunstwerk and open-ended multi-scalar design strategies that allow for both structural and organic development. The paper provides examples to support its proposal for the use of concrete aesthetic principles to guide Systemic Design processes. This paper expands the working paper entitled “Holistic and dynamic concepts in design: What design brings to systems thinking”, which was presented at the RSD3 symposium (2014).

The Interactive Electronic Technical Manual (IETM) can solve some practical application problems of the traditional paper technical manuals on storing difficulty and resource sharing inefficiency well. The S1000D specification is an international specification of development IETM. In the paper the S1000D specification is introduced briefly. Then the meanings of Data Module (DM) and Common Source Database (CSDB) which are the core concepts of the S1000D specification are analyzed. At last, the development process of IETM based on S1000D specification is given.
