“Fostered idols” refer to entertainment idols and young stars-in-the-making who begin their careers as amateurs. Today, the fostered idol model has become increasingly popular in China, and fans demonstrate incredible consumption power. Despite the booming market, little is known about this phenomenon. Therefore, this study aims to explore fans’ motivations and consumption practices from the consumer’s perspective within the framework of self-determination theory.

In all 20 in-depth interviews with fostered idol fans were conducted through online phone calls. The interviews were recorded, transcribed and subsequently analysed using a grounded approach.

The results indicate that fans’ consumption practices are motivated both intrinsically and extrinsically. Intrinsic motivation includes sensory pleasure while extrinsic motivations are composed of a sense of being needed and a sense of success. Extrinsic motivations play a dominant role and reflect the needs of relatedness and competence. Additionally, consumption practices are found to be consistent with motivations.

The results show the crucial role of psychological satisfaction experienced by fans in the consumption of the fostered idol and highlight the importance of a relatedness- and competence-supportive environment to secure fans’ persistent consumption and loyalty.

This study focuses on fans of fostered idols that has not been explored in existing studies and offers valuable insights regarding the similarities and differences between fan consumption in China and other Asian countries. The results will inform marketing practitioners for the development of effective strategies and business decisions.

Before the turn of the century, taking overseas students was more about a diplomatic issue dominated by the state in China, for which reason this section is relatively independent within the higher education system. However, evidence from a series of new policy documents and their impacts suggests that international student mobility (ISM) has been intensively shaped by the central government in the desire to promote its national strategy, namely the belt and road initiative. ISM policy, although with a significant proportion marketized, was introduced for a clear purpose of cultural diplomacy. The paper aims to discuss these issues.

Looking beyond the debate of market-driven vs state-dominated, this paper attempts to provide a thorough understanding of this changing pattern based on examination of key changes of policy statements along with official data analysis.

This paper argues that the new pattern must be understood against a context of a hierarchy of higher education institutes in contemporary China: a sector led by a small number of prestigious universities generously funded by the central government with a large number of ordinary universities underfunded and eager to generate income. Prestigious institutes enroll international students to satisfy performance indicators listed by policies like “Double First-rate”; other universities, benefiting from the reputation and momentum generated by the top ones, take self-funded students for profit.

By making good use of both performance indicators and market motives, the country managed to move a state-dominated ISM policy in the twentieth century into the existing state-steering marketization model and made China a major destination for overseas study.

This paper aims to propose a diverless weld bead maintenance welding technology to prevent the leakage of subsea oil and gas pipeline and solve the key problems in the maintenance of subsea pipeline.

Based on the analysis of the cross-section of the fillet weld, the multi-layer and multi-pass welding path planning of the submarine pipeline sleeve fillet weld is studied, and thus a multi-layer and multi-pass welding path planning strategy is proposed. A welding seam filling method is designed, and the end position of the welding gun is planned, which provides a theoretical basis for the motion control of the maintenance system.

The trajectory planning and adjustment of multi-layer and multi-pass fillet welding and the motion stability control of the rotating mechanism are realized.

It provides the basis for the prototype design of the submarine pipeline maintenance and welding robot system, and also lays the foundation for the in-depth research on the intelligent maintenance system of submarine pipeline.

The maintenance of diverless subsea pipeline is a new type of maintenance method, which can solve the problem of large amount of subsea maintenance work with high efficiency.

This study aims to decrypt the efforts made by Chinese people's courts nationwide to protect the rights of Chinese posted workers in the Belt & Road (B&R) countries by investigating labour litigation cases with an extraterritorial application of Chinese labour law (under the “doctrine of overriding mandatory labour rules”).

This study collected all labour litigation from 2014 to 2018 brought forward by Chinese posted workers in Chinese courts against Chinese enterprises regarding the performance of employment contracts in the B&R countries where Chinese labour laws were mandatorily applied under the doctrine of overriding mandatory labour rules. The study adopted a qualitive research approach to analyse the compiled cases to explore their characteristics and effects.

This study found that the volume of labour disputes in the B&R countries had a somewhat positive correlation to the amount of investment from China. However, this correlation was rather superficial when compared with the correlation to the type of industrial sector (e.g. the construction sector) and to the claim category (e.g. remuneration claims). Moreover, labour disputes in both the B&R countries and China shared a great deal of similarity with regard to their concentration in certain sectors and in certain types of claims. Therefore, mandatorily applying Chinese labour law could be convenient for Chinese workers returning from abroad who seek remedies and could allow Chinese judges to issue affirmative decisions regardless of the territory in which the worker was posted.

The cases collected by this study were limited to those filed in China by Chinese workers who were hired by Chinese enterprises and sent to work in the B&R countries and did not include those filed in the B&R countries by Chinese posted workers. Future research should therefore attempt to gather a broader range of labour disputes to further clarify the issues and need for labour protection for Chinese posted workers in the B&R countries.

This study argues that the doctrine of overriding mandatory labour rules is not entirely unproblematic because it might arbitrarily rule out the standards set by foreign labour legislation that could be more favourable to workers or offer them greater protection. Therefore, giving judges a certain degree of discretion is imperative to allow them to apply foreign labour standards when they have been proven to benefit workers.

Apart from a handful of reports on individual cases, there have been very few empirical studies regarding the general picture of labour protection for Chinese posted workers in the B&R countries. This study has adopted a novel approach to collect information on labour disputes in the B&R countries and to facilitate a qualitative analysis to test the practical implications of the doctrine of overriding mandatory labour rules.

With an increase in the amount of multilingual content on the World Wide Web, users are often striving to access information provided in a language of which they are non-native speakers. The purpose of this paper is to present a comprehensive study of user profile representation techniques and investigate their use in personalized cross-language information retrieval (CLIR) systems through the means of personalized query expansion.

The user profiles consist of weighted terms computed by using frequency-based methods such as tf-idf and BM25, as well as various latent semantic models trained on monolingual documents and cross-lingual comparable documents. This paper also proposes an automatic evaluation method for comparing various user profile generation techniques and query expansion methods.

Experimental results suggest that latent semantic-weighted user profile representation techniques are superior to frequency-based methods, and are particularly suitable for users with a sufficient amount of historical data. The study also confirmed that user profiles represented by latent semantic models trained on a cross-lingual level gained better performance than the models trained on a monolingual level.

Previous studies on personalized information retrieval systems have primarily investigated user profiles and personalization strategies on a monolingual level. The effect of utilizing such monolingual profiles for personalized CLIR remains unclear. The current study fills the gap by a comprehensive study of user profile representation for personalized CLIR and a novel personalized CLIR evaluation methodology to ensure repeatable and controlled experiments can be conducted.

Social factors can shape economic decisions. Corporate governance (CG) studies and guidelines usually neglect that the chief executive officer (CEO) and board members may be socially tied. This study investigates the effects of social ties between the CEO and board members on earnings management (EM).

The authors run a series of regressions using a sample of Brazilian companies listed on the Brazilian Stock Exchange [B]³ between 2011 and 2017 to assess the effect of the social ties between the CEO and board members on EM using a social ties index. The authors also employ five robustness tests to verify the consistency of results, including alternative proxies of EM and social ties and an estimation using fixed effects.

After developing and computing a social ties index between the CEOs and members of the board of directors (BD) and the fiscal council (FC), the study’s findings indicate that a significant level of social ties between the CEO and BD has a negative impact on EM. However, for FC members, the authors found non-significant results.

Unlike previous studies, the authors built a social tie index (STI) from five elements of social ties assessed in an environment with a two-tier board system. Results show that elements of social interactions and personal relationships can benefit the company, as a CEO's level of social ties with the BD reduces EM practices.

The purpose of this paper is to check the efficiency of isogeometric analysis (IGA) by comparing its results with classical finite element method (FEM), generalized finite element method (GFEM) and other enriched versions of FEM through numerical examples of free vibration problems.

Since its conception, IGA was widely applied in several problems. In this paper, IGA is applied for free vibration of elastic rods, beams and trusses. The results are compared with FEM, GFEM and the enriched methods, concerning frequency spectra and convergence rates.

The results show advantages of IGA over FEM and GFEM in the frequency error spectra, mostly in the higher frequencies.

Isogeometric analysis shows a feasible tool in structural analysis, with emphasis for problems that requires a high amount of vibration modes.

The problems of water supply of China in 2000 are revealed by statistical data. It is shown that 450 cities will be short of fresh water; a great quantity is utilised in agriculture much of which can be saved; groundwater is over‐extracted; the level of water is falling by an average of 1‐2mu each year which has caused the subsiding of regional earth; the quality of drinking water and of water utilised in industry becomes poorer; water resources are polluted because of the increase in organic pollutants, the number and size of cities, the pollution of nutrient and colon bacillus, the decrease in the area of lakes, the shortage of money for administration, the amount of polluted water drained without efficient treatment, the low re‐utilisation ratio of water, and the low rate of sewerage system development.

Green economy and economic development with high quality have set higher requirements for the development of the urban logistics industry. It can grasp the recent development level of the urban logistics industry by measuring its environmental efficiency to guide its future development direction. The purpose of this study is to improve the environmental efficiency and development level of the urban logistics industry by using a reasonable evaluation method.

This paper uses information entropy to directly aggregate index weights from different models to acquire comprehensive index weights (CIWs) for calculating peer-evaluation efficiency. Then, we weight self and peer-efficiencies to obtain final efficiency. The environmental efficiencies of the urban logistics industry in Anhui Province in 2019 are obtained according to the above method.

Several findings are summarized below. The logistics industry in Anhui is in urgent need of improving environmental efficiency. The environmental efficiency of the logistics industry in North Anhui is the highest one, showing that the logistics industry in North Anhui has achieved a relative balance between economic development and environmental protection. Their final cross-efficiency values based on the CIWs are smaller than those based on the comprehensive efficiency. And the environmental efficiency of almost all urban logistics industries is lower than its economic efficiency. The findings show that the proposed method is feasible and more reasonable. More economic implications and suggestions are proposed.

This paper proposes an extended cross-efficiency evaluation method based on information entropy to measure the environmental efficiency of the urban logistics industry, effectively avoiding the overestimation of efficiency results.

This paper aims presents topology optimization of microfluidic channels with reverse flow.

A circular chamber with an inlet and an outlet are chosen as an initial design domain. The energy dissipation is chosen as an objective function. The incompressible Navier–Stokes equation is applied for simulating the fluidic motion in channels. An artificial friction force which is proportional to the flow velocity is substituted into the Navier–Stokes equation for controlling the design variable.

The effect of a bifurcation angle between the inlet and the outlet on a topological structure is analyzed. The flow velocity, pressure and design variable for every bifurcation angle are obtained.

This work is instructive to the design of a microfluidic system.
