Abstract

Purpose

This study aims to model the creative pedagogy of children's book development and then engages teacher education students in this work, as a way to explore and express conceptions of teacher quality, across cultural perspectives.

Design/methodology/approach

This self-study engages a/r/tography and currere to explore teacher quality in a teacher education classroom in a Chinese university. A/r/tography (Irwin et al., 2006) considers teacher quality through the conventional lens based on standards and through a more aesthetic lens shaped by cultural nuances and personal experiences. This self-study engages currere (Pinar, 2004) as a methodology marked by contiguous living inquiry explored with an abstract lens aimed to see openings for insight leading to transformation (Pourchier, 2010).

Findings

Discussing similarities and distinctions across the presentation and conceptualization of teacher quality in the created children's books promoted dialogue considering intercultural, international pictures of a caring student–teacher relationship. A/r/tographic, currere approaches to exploring this enhanced reflective insight and supported acceptance of diverse notions of teacher quality.

Originality/value

As 21st-century global societies evolve, the meaning of progress also evolves from vertical linear trajectories to horizontal, webbed transformations, driven by differences leading to rhizomatic global connections. A/r/tography and currere are meaningful methodologies to explore the concept of teacher quality from aesthetic angles and on a more personal level so that our understandings may be shaped meaningfully by more diverse perspectives and voices.

Abstract

Purpose

The purpose of this paper is to attempt to calculate the trust degree between two enterprises in an industrial network using grey correlation degree algorithm for exploring characteristics of community structure and evolution rules of cluster cooperation networks in axle‐type and satellite‐type clusters.

Design/methodology/approach

Starting from analysis of trust formation mechanism of inter‐enterprise in industrial networks, adjacency of inter‐enterprise relationship, their information acquisition ability, their influence power in network and their past interaction experience are chosen as influencing factors of the trust between two enterprises. Grey correlation degree algorithm was chosen to calculate the trust degree between two enterprises in an industrial network. According to the rules of dynamic adjustment of trust degree originated from thoughts of the prisoners' dilemma model, computer simulation is applied to explore characteristics of community structure and evolution rules of cluster cooperation network in axle‐type and satellite‐type clusters.

Findings

With the dynamic adjustment of enterprises' trust degree, the network density of axle‐type and satellite‐type cluster networks was decreasing as the cluster scale was enlarging, and eventually tended to be stable; community structure was emerged in axle‐type and satellite‐type industrial clusters as the cluster scale was enlarging; community characteristics were obviously stronger in axle‐type cluster networks than in satellite‐type; communities were overlapped in axle‐type cluster networks, that is, bridge nodes emerged between communities.

Originality/value

This paper is the first to apply the grey correlation degree algorithm to calculate the trust degree between two enterprises in cluster networks for designing the rules of dynamic adjustment of trust degree.

Abstract

Purpose

Fifth-generation (5G) networks play a significant role in handover methods. 5G wireless network is open, flexible and highly heterogeneous along with the overlay coverage and small cell deployments. Handover management is one of the main problems in the heterogeneous network. Also, handover satisfies the needs of ultra-reliable communications along with very high reliability and availability in 5G networks. Handover management deals with every active connection of a user’s device, which moves the connection between the user’s device and the counterparty from one network point to another. Thus, the handover decision determines the best access network and also decides whether the handover is performed or not.

Design/methodology/approach

The main intention of this survey is to review several existing handover technologies in 5G. Using the categories of analysis, the existing techniques are divided into different techniques such as authentication-based techniques, blockchain-based techniques, software-defined-based techniques and radio access-based techniques. The survey is made by considering the methods such as used software, categorization of methods and used in the research works. Furthermore, the handover rate is considered for performance evaluation for the handover techniques in 5G. The drawbacks present in the existing review papers are elaborated in research gaps and issues division.

Findings

Through the detailed analysis and discussion, it can be summarized that the widely concerned evaluation metric for the performance evaluation is the handover rate. It is exploited that the handover rate within the range of 91%–99% is achieved by three research papers.

Originality/value

A survey on the various handover mechanisms in 5G networks is expected in this study. The research papers used in this survey are gathered from different sources such as Google Scholar and IEEE. Also, this survey suggests a further extension for the handover mechanism in 5G networks by considering various research gaps and issues.
