Abstract

Purpose

Regulating and guiding the sound development of capital under a socialist system is not only a significant theoretical innovation rooted in Chinese practice by the Communist Party of China (CPC) but also a major practical exploration for the smooth progression of the party and the nation’s modernization endeavors.

Design/methodology/approach

Adopting an analytical framework that unifies theoretical, historical and practical logic, this paper explores the rationality of capital’s existence under a socialist system based on the notion that capital is a materialized production relationship. It also examines the staged evolution of capital theory under socialism, highlighting the great leap forward realized by the capital theory of socialism with Chinese characteristics.

Findings

With the CPC Central Committee’s deepening understanding of the capital patterns in the socialist system, capital-related policies have undergone a developmental journey through several stages – from the negation and elimination of capital to the support and operation of capital and finally to the stage of regulating and guiding capital. This reflects the reciprocal and complementary relationship between capital theory and capital policy.

Originality/value

In response to issues such as the disorderly expansion of capital in the new development stage, it is imperative to actively promote a practical pathway safeguarded by the adherence to Party leadership, guided by the capital theory of socialism with Chinese characteristics and targeted toward common prosperity.

Abstract

Purpose

Endwall film cooling protects vane endwall by coolant coverage, especially at the leading edge (LE) region and vane-pressure side (PS) junction region. Strong flow impingement and complex vortexaa structures on the vane endwall cause difficulties for coolant flows to cover properly. This work aims at a full-scale arrangement of film cooling holes on the endwall which improves coolant efficiency in the LE region and vane-PS junction region.

Design/methodology/approach

The endwall film holes are grouped in four-holes constructal patterns. Three ways of arranging the groups are studied: based on the pressure field, the streamlines or the heat transfer field. The computational analysis is done with the k-ω SST model after validating the turbulence model properly.

Findings

By clustering the film cooling holes in four-holes patterns, the ejection of the coolant flow is stronger. The four-holes constructal patterns also improve the local coolant coverage in the “tough” regions, such as the junction region of the PS and the endwall. The arrangement based on streamlines distribution can effectively improve the coolant coverage and the arrangement based on the heat transfer distribution (HTD) has benefits by reducing high-temperature regions on the endwall.

Originality/value

A full-scale endwall film cooling design is presented considering interactions of different film cooling holes. A comprehensive model validation and mesh independence study are provided. The cooling holes pattern on the endwall is designed as four-holes constructal patterns combined with several arrangement choices, i.e. by pressure, by heat transfer and by streamline distributions.

Abstract

Purpose

Unlike conventional aircraft, birds can glide without a vertical tail. The purpose of this paper is to analyse the influence of dihedral angle spanwise distribution on lateral-directional dynamic stability by the simulation, calculation in the development of the bird-inspired aircraft and the flight testing.

Design/methodology/approach

The gliding magnificent frigatebird (Fregata magnificens) was selected as the study object. The geometric and mass model of the study object were developed. Stability derivatives and moments of inertia were obtained. The lateral-directional stability was assessed under different spanwise distributions of dihedral angle. A bird-inspired aircraft was developed, and a flight test was carried out to verify the analysed results.

Findings

The results show that spanwise distribution changing of dihedral angle has influence on the lateral-directional mode stability. All of the analysed configurations have convergent Dutch roll mode and rolling mode. The key role of dihedral angle changing is to achieve a convergent spiral mode. Flight test results show that the bird-inspired aircraft has a well-convergent Dutch roll mode.

Practical implications

The theory that birds can achieve its lateral-directional stability by changing its dihedral angle spanwise distribution may explain the stability mechanism of gliding birds.

Originality/value

This paper helps to improve the understanding of bird gliding stability mechanism and provides bio-inspired solutions in aircraft designing.

Abstract

Purpose

Global climate change speeds up ice melting and increases flooding incidents. China launched a sponge city policy as a holistic nature-based solution combined with urban planning and development to address flooding due to climate change. Using Weibo analytics, this paper aims to study public perceptions of sponge city.

Design/methodology/approach

This study collected 53,586 sponge city contents from Sina Weibo via Python. Various artificial intelligence tools, such as CX Data Science of Simply Sentiment, KH Coder and Tableau, were applied in the study.

Findings

76.8% of public opinion on sponge city were positive, confirming its positive contribution to flooding management and city branding. 17 out of 31 pilot sponge cities recorded the largest number of sponge cities related posts. Other cities with more Weibo posts suffered from rainwater and flooding hazards, such as Xi'an and Zhengzhou.

Originality/value

To the best of the authors’ knowledge, this study is the first to explore the public perception of sponge city in Sina Weibo.

Abstract

Purpose

This study embraces the call for exploring the determinants of continuous intention in TikTok. Taking the perspective of social influence, this study not only tries to explore the contextual sources of two types of social influence but also aims to unveil the influence mechanism of how social influence affects TikTok viewers’ continuous intention.

Design/methodology/approach

This study empirically analyzes how TikToker attractiveness, co-viewer participation, platform reputation and content appeal affect informative and normative social influence and then lead to the continuous intention of TikTok. Based on 547 valid survey data, this study adopts a mixed analytical approach for data analysis by integrating structural equation modeling (SEM) and fuzzy-set qualitative comparative analysis (fsQCA).

Findings

SEM results unveil that content appeal is the most critical antecedent of informational social influence, while the TikToker attractiveness and platform reputation have no effect on it. Differently, all four external sources positively lead to normative social influence. Among them, content appeal and co-viewer participation influence the most. The influences of both two types of social influence on continuous intention are demonstrated. FsQCA results reveal seven alternative configurations that are sufficient for influencing continuance intention and further complement and reinforce the SEM findings.

Originality/value

Addressing the critical contextual elements of TikTok, this study explores and confirms the sources which may engender social influence. The authors also demonstrate the critical role of social influence in affecting TikTok viewers’ continuous intentions by the hybrid analytical approach, which contributes to existing academic literature and practitioners.

Abstract

Purpose

Central to this paper, Western international political economy cannot well explain China’s peaceful development and its political and economic ties with the outside world, and it is even more difficult to reflect the characteristics of the times that the great changes unseen in a century and socialism with Chinese characteristics have entered into a new era, which are synchronously intertwined and mutually agitated. Constructing China’s international political economy not only emphasizes the Chinese perspective, Chinese discourse and Chinese narrative but also examines the development trend and major problems facing the world from the height of world history and applies the position, viewpoints and methods of Marxist historical materialism to observe the times, interpret the times and lead the times.

Design/methodology/approach

Looking back at the development of China’s international political economy, from introducing Western international political economy to increasingly emphasizing the Chinese perspective, Chinese discourse and Chinese narrative, we analyze the distinctive features of China’s international political economy from Western international political economy.

Findings

The thought of community with a shared future for mankind is the latest development and concentrated embodiment of Marxist thought on world history in the 21st century, which gives China’s international political economy a distinctive epochal, scientific and practical character, stipulates the research stance and fundamental purpose, establishes the research theme and main line and expands the research space for the construction of Chinese international political economy.

Originality/value

The construction of China’s international political economy is not only to create a “Chinese school” of international relations but more importantly to construct a discourse and academic system of China’s international political economy that can understand and grasp the changes in the world, the times and history, providing academic support for in-depth thinking and answering the question of “What is wrong with the world? What should we do?” and contributing Chinese wisdom.

Abstract

Purpose

The purpose of this paper is to establish and implement a direct topological reanalysis algorithm for general successive structural modifications, based on the updating matrix triangular factorization (UMTF) method for non-topological modification proposed by Song et al. [Computers and Structures, 143(2014):60-72].

Design/methodology/approach

In this method, topological modifications are viewed as a union of symbolic and numerical change of structural matrices. The numerical part is dealt with UMTF by directly updating the matrix triangular factors. For symbolic change, an integral structure which consists of all potential nodes/elements is introduced to avoid side effects on the efficiency during successive modifications. Necessary pre- and post processing are also developed for memory-economic matrix manipulation.

Findings

The new reanalysis algorithm is applicable to successive general structural modifications for arbitrary modification amplitudes and locations. It explicitly updates the factor matrices of the modified structure and thus guarantees the accuracy as full direct analysis while greatly enhancing the efficiency.

Practical implications

Examples including evolutionary structural optimization and sequential construction analysis show the capability and efficiency of the algorithm.

Originality/value

This innovative paper makes direct topological reanalysis be applicable for successive structural modifications in many different areas.

Abstract

Purpose

In human history, poverty for most and prosperity for few is the norm. Thus, no theory or practice of common prosperity has been developed. Marxism first formulated the theory of common prosperity, and the classical Marxist authors conducted theoretical exploration on the issue of common prosperity, forming a series of scientific conclusions.

Design/methodology/approach

The century-long practical history of the Communist Party of China (CPC) is the great practice of leading the Chinese people in getting rid of poverty, letting some people and regions get rich first and ultimately achieving the goal of common prosperity.

Findings

Common prosperity is the great practice of the CPC that leads all Chinese people in building a modern socialist country in an all-round way in the new era.

Originality/value

The path of common prosperity with Chinese characteristics will certainly arise in the process of the great practice of common prosperity with Chinese characteristics. Based on the anti-poverty theory and the “spirit of poverty alleviation” from the battle against poverty with Chinese characteristics, the theory of common prosperity and its spirit with Chinese characteristics will certainly be formed. The above conclusions constitute the basic principles of the theory of common prosperity with Chinese characteristics.

Abstract

Emergency logistics is an important means to deal with disasters and public crises. Since the outbreak of the severe acute respiratory syndrome (SARS) virus in 2003, China has established and developed an emergency logistics management system. With the outbreak of coronavirus disease (COVID-19) in China, its emergency logistics system is facing unfolded challenges. The main purposes of this study are to explore the development of China’s emergency logistics system in this context and identify the critical success factors for such systems. A series of focus groups are organized to collect the opinions of 24 interviewees from three Chinese cities, namely Wuhan, Shanghai, and Xi’an. Through the analysis, a framework of the critical success factors for emergency logistics in China is recreated. The key elements are demand forecasting and planning, inventory management, distribution network, and systematic information management. Findings suggest critical points on the design and imple-mentation of the emergency logistics operations during a chaotic period.
