Abstract

Purpose

General Secretary Xi Jinping pointed out that to uphold and develop socialist political economics with Chinese characteristics, the authors should be guided by Marxist political economics.

Design/methodology/approach

It is an essential methodological principle for building a theoretical system of socialist political economics with Chinese characteristics as a “systematic economic theory”.

Findings

To implement this principle, the authors need to understand the rich connotation of Marxist political economics and its relationship with socialist political economics with Chinese characteristics fully and correctly and unswervingly uphold and inherit, creatively transform and innovatively develop the theoretical achievements of Marxist economics, especially capital.

Originality/value

It is also an essential and necessary way to build a theoretical system of socialist political economics with Chinese characteristics.

Abstract

Purpose

The world currency is endowed with two inherent contradictions, namely, the general contradiction of all currencies and the special contradiction between the quality and quantity of the world currency. The paper aims to discuss these issues.

Design/methodology/approach

In the wake of the Second World War, the USA, with its strong economic and military strength, established an international monetary system centered on the US dollar (USD). This gave USD the status of “world currency” and bounded it to the US imperialist hegemony with mutual integration and interaction, making it possible for USD capital to conduct international exploitation and wealth plundering extensively around the world.

Findings

The contradiction between the capital logic and the power logic, which is inherent in capital accumulation models of the new imperialism, also indicates the inevitable decline of USD.

Originality/value

This constitutes an important feature of the new imperialism. However, as a sovereign currency, USD has inextricable and inherent contradictions while exercising its function as the world currency.

Abstract

Purpose

The purpose of this paper is to further explore the co-citation and bibliographic-coupling relationship among the core authors in the field of Chinese information science (IS), to expose research activity and author impact, and to make induction analyses about Chinese IS research patterns and theme evolution.

Design/methodology/approach

The research data include 8,567 papers and 70,947 cited articles in the IS field indexed by Chinese Social Sciences Citation Index from 2000 to 2009. Author co-citation analysis, author bibliographic-coupling analysis, social network analysis, and factor analysis were combined to explore co-citation and bibliographic-coupling relationships and to identify research groups and subjects.

Findings

Scholars with greatest impact are different from the most active scholars of Chinese IS; there is no uniform impact pattern forming since authors’ impact subjects are scattered and not steady; while authors’ research activities present higher independence and concentration, there is still no steady research pattern due to no deep research existing. Furthermore, Chinese IS studies can be delineated by: foundation or extension. The research subjects of these two parts, as well as their corresponding/contributing authors, are different under different views. The general research status of core authors is concentrated, while their impact is broad.

Originality/value

The combined use of some related methods could enrich the development and methodology research of the discipline, and the results establish a reference point on the development of IS research.

Abstract

Purpose

An electromagnet that can produce strong pulsed magnetic fields at kHz frequencies is potentially very favourable to exert a Lorentz force on the metallic workpiece. One of the applications of the pulsed magnetic field is the electromagnetic forming where the design of robust electromagnet is critical. The purpose of this paper is to design a robust electromagnet (coil) for high velocity electromagnetic tube forming operation.

Design/methodology/approach

First of all, an analytical model is developed to design the electromagnet and predict the aluminium tube velocity under the action of the estimated pulsed magnetic field. Next, the finite element-based numerical model is used to test the robustness of the designed coil and validate the analytical model. The coil is fabricated and implemented for free forming of aluminium tube. Experimental results of tube displacement are further compared with numerical and analytical model results.

Findings

The experimental tube displacement results are showing a good match with analytical and numerical results. The designed electromagnet has generated a peak magnetic field around 14 T at 20 µs rise time and deformed the aluminium tube with a peak velocity of 160 m/s. Robustness of the electromagnet under the action of forming stress is insured by numerical stress analysis and experiments.

Practical implications

Though the designed model in this work is for the 2.4 mm aluminium tube forming, it can also be used for different tube materials, tube dimensions and other electromagnetic forming applications with some modifications.

Originality/value

The research results provide powerful theoretical, numerical simulation and experimental support for the robust electromagnet design.
