Abstract

Flexibility is a basic requirement to cope with complexity and dynamics. The aim of this chapter is to analyze to which extent self-organization can support integrating flexibility in the processes of competence-building and competence-leveraging. The objective of this discussion is therefore to deduce possible contributions of the concept of self-organization to a strategic competence-based management in regard to effects of flexibilization.

Abstract

Purpose

The purpose of this study is to propose a modeling method of the equivalent circuit for a new type of high-temperature superconducting partial-core transformer (HTS-PCT) made of ReBCO-coated conductors.

Design/methodology/approach

The modeling process is based on the “Steinmetz” equivalent circuit. The impedance components in the circuit are obtained by the calculations of the core losses and AC losses of the HTS windings by using theoretical methods. An iterative computation is also used to decide the equivalent resistances of the AC losses of the primary and secondary HTS windings. The reactance components in the circuit are calculated from the energy stored in the magnetic fields by finite element method. The validation of the modeling method is verified by experimental results

Findings

The modeling method of the equivalent circuit of HTS-PCT is valid, and an equivalent circuit for HTS-PCT is presented.

Practical implications

The equivalent circuit of HTS-PCT could be obtained by the suggested modeling method. Then, it is easy to analyze the characteristics of the HTS-PCT by its equivalent circuit. Moreover, the modeling method could also be useful for the design of a specific HTS-PCT.

Originality/value

The study proposes a modeling method of the HTS-PCT made of the second-generation HTS tapes, i.e. ReBCO-coated conductors.

Abstract

Purpose

To provide a validation of a three‐dimensional (3D) macroscopic model for superconductors comparing numerical to experimental AC losses of a BSCCO‐2223 tape subject to an orthogonal magnetic field and a transport current.

Design/methodology/approach

We solve in 3D geometries the eddy current problem in presence of superconductors, represented by a power‐law characteristic rewritten into a variational form. An integral formulation of the magneto‐quasistatic Maxwell's equations is used. The solution of the problem is found by an unconstrained minimization of a suitable functional. The numerical results on AC losses computation are compared to experimental data.

Findings

The agreement between numerical and experimental data is good in a wide range of currents and magnetic fields.

Research limitations/implications

The magnetic field is assumed to be orthogonal to the tape. Different incidence angles should be taken into account.

Practical implications

It is possible to extend the range of validity of the engineering formulae for AC losses used in the work.

Originality/value

The paper provides a validation of a numerical code against experimental results: this is always challenging in the field of applied superconductivity.

Abstract

Purpose

The purpose of this paper is to investigate the impacts of technological capability (TC) and technology management (TM) on the development of China’s telecommunications industry by examining two interrelated questions: Which is the order parameter for China’s telecommunications industry? and What are the relationships between TC and TM? The paper will develop models to analyze TC, TM and the development of China’s telecommunications industry quantitatively.

Design/methodology/approach

The paper reviews literature related to TC and TM and investigates the technical features of China’s telecommunications industry. Then, the paper makes a theoretical analysis of the relationships among them. First, it analyzes the effects of TC and TM on the industry and tries to explore the order parameter. Second, the paper analyzes the interaction between TC and TM. Then, the paper applies the Haken model to construct an analysis model. It also constructs models for measuring TC and TM. Using the data of China’s telecommunications industry from 1991 to 2010, the paper identifies the order parameter for the industry and tests the relationships between TC and TM.

Findings

The paper finds that TC plays a dominant role in the development of China’s telecommunications industry. The paper also finds that TC promotes the development of TM. However, TM fails to promote the development of TC. The paper presents two other important findings. The first one is that China’s telecommunications industry has constructed a positive feedback mechanism for continuous development of TC, which provides an impetus for industry upgrades and development. The second one is that there is no positive feedback growth mechanism for TM capability, which has increased the lag between TM and TC and has become one of the important reasons why TM does not promote TC.

Research limitations/implications

Theoretical and managerial implications are put forward. Thus, TC must be improved to propel the development of China’s telecommunications industry; TM should be greatly improved and an effective growth mechanism for TM should be constructed; the synergy between TM and TC should be achieved. Research limitations are also pointed out. Thus, the results in this paper probably cannot be generalized to other industries; it does go on to discuss the synergetic mode of TM and TC that can best compel industrial development, and it does not explain what the growth mechanisms for TM and TC should be.

Originality/value

The paper is original, as it provides new perspectives of TM and TC for analyzing industrial development, and it provides the method and model for quantitatively analyzing TC and TM at an industry level. It discovers the order parameter and new problems of China’s telecommunications industry, which no one has identified before. The paper also offers references for analyzing other industries from the perspectives of TM and TC.

Abstract

Emery and Trist were the first to design an influential taxonomy of four social fields to accommodate the perceived emergence of a new type of business environment, the type 4 turbulent field. This captured the predicament of leading companies suddenly confronted with, what Christensen called much later, disruptive change. Their taxonomy was based on the study of adaptive behavior on linear dynamical systems. This paper proposes a modification of the taxonomy on the basis of Synergetics to enable dealing with the nonlinear evolutionary dynamics of complex probabilistic business systems. Synergetics focuses on what happens in phase transitions or bifurcations which appear to be the essential nature of turbulent fields. Furthermore, Haken's slaving principle and the concept of the order parameter are remarkably well‐suited to review the Christensen's findings of companies held captive by customers and, particularly, the puzzling delay shown by leading companies in responding to newcomers. These newcomers typically change the nature of the order parameters of type 3 established fields, as represented by Christensen's product performance characteristics, which may cause customers to switch their preferences and buying behavior. Thus the apparent stability of an established field can be quite deceptive. As such, this paper suggests the existence of a lock‐out principle complementary to the lock‐in principle described by Arthur in his work.

Abstract

The analysis of acetate acrylic and acrylic copolymers systems is described. Much useful information is rapidly obtained by infra‐red spectrophotometry and pyrolysis gas chromatography, however quantitative analyses generally require the polymer material to be cleaved by chemical means with subsequent identification of the fragments by gas chromatography.

Abstract

Purpose

This study aims to provide a fresh perspective toward understanding the forces that exist in the guest-host dynamic and thereby contribute to the guest–host relationship literature.

Design/methodology/approach

This study examines guest–host relationship via the philosophical lens of convivialism.

Findings

This study conceptualizes conviviality in the guest–host relationship. A convivial guest–host relationship is characterized by well-being mutuality and hospitality mutuality. Such a relation can be built when the guest and the host form a tri-party of coalitions, namely, economic, experience and hospitality. While an economic coalition represents the pragmatic value in a guest–host relationship, an experience coalition represents an experiential value in a guest–host relationship. A hospitality coalition then represents the spiritual alliance in such a relationship.

Practical implications

This paper suggests that tourism development should be guided by a conviviality vision. Health and well-being of both the visitors and the destination community should be a goal priority. This paper suggests that the starting point of experience planning is the residents, not the visitors. The critical role of hospitality in formulating market communication strategies is emphasized.

Social implications

This study contributes to the larger conversation of diversity and sustainability.

Originality/value

This study proposes a convivial tourism model – a form of tourism that is oriented toward mutuality of hospitality and well-being of both visitors and destination communities.

Abstract

Purpose

To take relative actions to cope with the threat which network finance information security now encounters by constructing controlling tactical and synergetic model.

Design/methodology/approach

It is practical to use the synergetic self‐organization theory to calculate the effects that the force of synergetic system of controlling tactics to financial information security makes on network financial system, and it is also practical to construct the synergetic model of controlling tactics to network financial information security on the basis of it.

Findings

Through applying synergetic analysis to controlling tactical system of network financial information security, it can be found out that controlling tactical system is an open system which changes from disorder to order and which keeps away from a balancing state. As an opening system, controlling tactics are interacting with outside from now and then.

Research limitations/implications

Network financial information security takes on dynamics, relativity, integrity and complexity. Accessibility of data is the main limitations which model will be applied.

Practical implications

From the view of network financial information security, constructing controlling tactical and synergetic model of information security are explained.

Originality/value

Network finance is orientated as a special social and economic system. The author does analysis on the network financial system, and expounds order parameters and model of network financial system.
