Abstract

Purpose

The purpose of this paper is to present a robotic off-line programming method for freeform surface grinding based on visualization toolkit (VTK). Nowadays, manual grinding and traditional robot on-line programming are difficult to ensure the surface grinding accuracy, thus off-line programming is gradually used in grinding, however, several problems are needed to be resolved which include: off-programming environment depends on the third-party CAD software, leads to insufficient self-development flexibility; single support for robot type or workpiece model format contributes to lack of versatility; grinding point data depends on external data calculation and import process, causes human-computer interaction deterioration.

Design/methodology/approach

In this method, the visualization pipeline and observer/command mode of VTK are used to display the 3D model of the robot grinding system and pick up the workpiece surfaces to be grinded respectively. Two groups of cutter planes with equidistant spacing are created to form the grinding nodes on the surface, and the extraction method for the position and posture of the nodes is proposed. Furthermore, the position and posture of discretized points along the grinding curve are obtained by B-spline curve interpolation and quaternion spherical linear interpolation respectively. Finally, the motion simulation is realized by robot inverse kinematics.

Findings

Through a watch case grinding experiment, the results show that the proposed method based on VTK can achieving high precision grinding effect, which is obviously better than traditional method.

Originality/value

The proposed method is universal which does not depend on the specific forms of surface, and all calculations in simulation are completed within the system, avoiding tedious external data calculation and import process. The grinding trajectory can be generated only by the mouse picking operation without relying on the other third-party CAD software.

Abstract

Purpose

The purpose of this study is to investigate how individuals' prosocial motivation affects their social entrepreneurship intentions (SEI) through the mediating effect of creativity and the moderating effect of family-to-work support.

Design/methodology/approach

A questionnaire survey was conducted in the Pearl River Delta region in Guangdong, China, and data were collected from 318 respondents who had rich social work experience. To test the hypotheses, a hierarchical linear regression analysis was conducted using SPSS 24.0 software.

Findings

Results offer empirical support for the hypotheses that creativity in social work plays a full mediating role in the relationship between individuals' prosocial motivation and SEI, and family-to-work support plays a positive moderating role in the relationship between creativity in social work and SEI.

Research limitations/implications

This study shows the importance of prosocial motivation, creativity in social work and family support in driving individuals' social entrepreneurship intentions and behaviours. Future research needs to further examine how the dynamic relationships between these factors unfold over time, as well as consider the effect of other motivational factors on creativity and SEI.

Practical implications

This study suggests that the cultivation of individual prosocial motivation is crucial and requires the efforts of family, school and society. Relevant organisations should encourage individuals to incorporate creative thinking into their work, as well as offer training opportunities. In addition, social entrepreneurs should also strengthen communication with their families and strive to gain their understanding and support.

Originality/value

The findings of this study extend existing views on the relationship between individuals' motivation and entrepreneurship intentions in the social entrepreneurship research field by focusing on the perspective of prosocial motivation. In particular, this study reveals the complex process of how prosocial motivation promotes SEI by identifying the role of creativity and family-to-work support, which has rarely been explored in the extant literature.

Abstract

Purpose

This study explores how to develop high-tech industries in Hunan province and enhance regional competitiveness. Through the comprehensive quantitative analysis of the development status of the high-tech industry in Hunan province, this paper provides a reference for the development of the high-tech industry in China and the world.

Design/methodology/approach

This study constructs a comprehensive evaluation index system of regional competitiveness in Hunan province from the five dimensions of innovation, coordination, green, openness and sharing of the “new development concept.” Through the screening and analysis of relevant economic indicators in Hunan province from 2011 to 2020, the principal component analysis method is used to measure the five development dimensions, verify the hypotheses in the study and finally draw the conclusion.

Findings

Hunan's high-tech industry is positively correlated with Hunan's regional innovation development competitiveness, regional coordinated development competitiveness, regional green development competitiveness, regional open development competitiveness and regional shared development competitiveness. Among them, the promotion effect on innovation development is the best, followed by the promotion effect on green development, coordinated development and shared development dimension. In contrast, the promotion effect on the open development dimension is relatively weak.

Research limitations/implications

The statistical data selected in this study have certain timeliness. At the same time, the current economic environment is affected by the new corona pneumonia epidemic, showing specific particularity. In this context, it is bound to cause changes in the impact of high-tech industries on regional competitiveness. In addition, this paper studies the regional competitiveness of Hunan's high-tech industry from a macro perspective. Although relevant studies are conducted from five dimensions, there is a lack of micro-level research.

Social implications

From five aspects of the new development concept, this study provides suggestions for developing high-tech industries in Hunan province and even China and the path to enhance regional competitiveness.

Originality/value

Up to now, no article measures regional competitiveness with the five development dimensions of new development: innovation, coordination, green, openness and sharing, and quantitatively analyses regional competitiveness on this basis.

Abstract

Purpose

The purpose of this report is to demonstrate open and distance education (ODE) can support poverty alleviation. Taking the practices of the Open University of China (the OUC) as an example, this paper aims to reveal how open universities make contributions to local residents in rural and remote areas.

Design/methodology/approach

Focusing on 25 poverty-stricken counties, the OUC had invested 58 million RMB to its learning centers in these counties from 2017 to 2020. The first one is to improve ICT and educational facilities in these learning centers. The second approach is to cultivate local residents with degree programs through ODE so as to promote local economic development. The third one is to design and develop training programs according to local context to meet the specific needs of local villagers.

Findings

After 3 years working, cloud-based classrooms and computer rooms have been set up. Bookstores have been founded and printed books have been donated. Hundreds of thousands of digital micro lectures have been supplied to these learning centers which have been improved and fully played their functions. Nearly 50,000 local residents have been directly benefited. Village leaders have helped lift local residents out of poverty. Poverty-stricken villagers have been financed to study on either undergraduate or diploma programs. Local residents have improved their skills by learning with the training programs offered by the OUC.

Originality/value

ODE is proved to be an effective way to eradicate poverty. Open universities are proved to be able to make contributions to social justice. By fulfilling its commitments to eliminate poverty within the national strategy framework, the OUC has built its brand nationwide.

Abstract

Purpose

A qualitative development is discernible in China’s pursuit of global influence in knowledge following the launch of the Belt and Road Initiative (BRI). China has embarked on expanding the frontiers of its higher education and research enterprise in different geographies, a subset of its global power project. This paper employs the geointellect concept to analyze this phenomenon.

Design/methodology/approach

The paper applies the geointellect model, formed inductively, to illuminate China’s geographical expanse in higher education and research.

Findings

The BRI has provided a platform for China to shape the educational architecture of the participating countries, apart from receiving a boost in its prestige by leading educational alliances and opening overseas research centres. In quantitative terms, it has made progress in specific knowledge metrics. Nevertheless, certain challenges and limitations need to be overcome.

Research limitations/implications

The role of a foreign policy in boosting a country’s knowledge profile has been identified. Future research directions have been provided in using the geointellect model.

Practical implications

This study provides a direction to evaluate the implications of China’s foreign policy for its knowledge segment, especially in terms of capturing its leading prowess in higher education and research.

Originality/value

It contributes a conceptual model to capture the different facets of China’s geointellect, with foreign policy, geography, higher education, and research being its constituents.

Abstract

Purpose

Using China’s key audit matters (KAMs) data, this study aims to examine whether negative press coverage alleviates boilerplate KAMs.

Design/methodology/approach

This study uses Levenshtein edit distance (LVD) to calculate the horizontal boilerplate of KAMs and investigates how boilerplate changes under different levels of the perceived legal risk.

Findings

The findings indicate that auditors of firms exposed to substantial negative press coverage will reduce the boilerplate of KAMs. This association is more significant for auditing firms with lower market share and client firms with higher financial distress. Additionally, the authors find that negative press coverage is more likely to alleviate the boilerplate disclosure of KAMs related to managers’ subjective estimation and material transactions and events. Furthermore, the association between negative press coverage and boilerplate KAMs varies with the source of negative news.

Originality/value

The findings suggest that upon exposure to negative press coverage, reducing the boilerplate of KAMs has a disclaimer effect for auditors.

Abstract

Purpose

The purpose of this paper is to examine the relationships between education and competencies from a comparative view, while controlling for background characteristics (e.g. parental education), home features (e.g. income) and country fixed effect.

Design/methodology/approach

This paper utilises an international data sets of 12 Belt and Road (B&R) countries participating in the PIAAC survey. Data are examined using regression models with “REPSET” Stata code. The focus on B&R countries is interesting as this recent economic and strategic development alliance might transform the contemporary global balance of power. Therefore, examining its educational development is important.

Findings

Findings reveal the higher the level of education, the higher the competency level in numeracy and literacy. Age was found to be negatively related to competencies, and gender was found to be dually significant. Among the examined B&R countries, Slovenia, Russia and Israel contribute the most to the numeracy, literacy and problem solving competencies (respectively) compared with other countries. The findings might contribute to the design of education for development policies aimed at increasing the level of state competitiveness while accounting for social cohesiveness.

Originality/value

The paper provides a comparative study into educational development of the B&R alliance, and therefore offers an insight of the developmental cooperation as it emerges. The focus on the B&R initiative is important as it is a strategic development alliance which might transform the contemporary global balance of power. Therefore, the examination of the above-mentioned relationships with the focus on B&R countries might advance the strategic design of this cooperation.

Abstract

Purpose

Existing research focuses on the pension systems and reforms in China from a macro-level and financial perspective. The expectations of mid-life Chinese people regarding their retirement and pensions have been ignored to date, and this research set out to address this lacuna.

Design/methodology/approach

The application of qualitative research methods is relatively novel in Chinese social science. As a grounded theory (GT) study, the research reported here deployed semi-structured interviews to investigate middle-aged Chinese women's and men's perceptions of their pensions and retirement. In total, 36 interviews were conducted, following the constructivist GT method.

Findings

The data point to disparities between the choices and perceptions of individuals on the one hand and the official assumptions underlying the current pension regime on the other hand. Research participants had varying interpretations of the inequality in retirement incomes in China, the main division being between enterprise workers and public-sector employees.

Originality/value

Although there are in principle rigidly fixed retirement ages for men and women in contemporary China, the phenomena of early retirement and working post-retirement are increasing. There are trade-offs between work/retirement and family needs, which influence the choices of middle-aged citizens. Retirement pathways are increasingly individualised, reflecting broader patterns of individualisation and inequality in China.

Case overview

Yongye Group is a biotechnological enterprise in Inner Mongolia, China. In China, people lack trust in economic transactions due to the transitional state of the economy, especially regarding food safety. To respond to this situation, Wu Zishen, the chairman of the Board of Directors of Yongye Group, was determined to build trust among employees, distributors, farmers, and consumers towards the company. To this end, he started using a creative incentive system with employees and stakeholders: the pay-before-performance incentive system. According to this system, the reward is delivered in advance, contrary to be paid after the fulfillment of the task. This practice is meant to transform employees' work attitude from a passive “being told to work” to a more proactive “I want to work” mentality. When such an incentive system is practiced with customers and external distributors, it sends a message that the company is “treating customers as company employees”, which means that they are trusted as if they were part of the company itself. Wu Zishen also introduced a coherent series of leadership practices that generate a truly proactive culture in the organization.

Expected learning outcomes

From this case, students will learn how to create a proactive culture in business organizations and the effect of pay-before-performance on employees' work motivation.

Supplementary materials

Teaching notes and an exercise for class-based discussion are available.

Abstract

Purpose

The purpose of this paper is to propose a new casualty scheduling optimisation problem and to effectively treat casualties in the early stage of post-earthquake relief.

Design/methodology/approach

Different from previous studies, some new characteristics of this stage are considered, such as the grey uncertainty information of casualty numbers, the injury deterioration and the facility disruption scenarios. Considering these new characteristics, we propose a novel casualty scheduling optimisation model based on grey chance-constrained programming (GCCP). The model is formulated as a 0–1 mixed-integer nonlinear programming (MINP) model. An improved particle swarm optimisation (PSO) algorithm embedded in a grey simulation technique is proposed to solve the model.

Findings

A case study of the Lushan earthquake in China is given to verify the effectiveness of the model and algorithm. The results show that (1) considering the facility disruption in advance can improve the system reliability, (2) the grey simulation technology is more suitable for dealing with the grey uncertain information with a wider fluctuation than the equal-weight whitening method and (3) the authors' proposed PSO is superior to the genetic algorithm and immune algorithm.

Research limitations/implications

The casualty scheduling problem in the emergency recovery stage of post-earthquake relief could be integrated with our study to further enhance the research value of this paper.

Practical implications

Considering the facility disruption in advance is beneficial to treat more patients. Considering the facility disruption in the design stage of the emergency logistics network can improve the reliability of the system.

Originality/value

(1) The authors propose a new casualty scheduling optimisation problem based on GCCP in the early stage of post-earthquake relief. The proposed problem considers many new characteristics in this stage. To the best of the authors' knowledge, the authors are the first to use the GCCP to study the casualty scheduling problem under the grey information. (2) A MINP model is established to formulate the proposed problem. (3) An improved integer-encoded particle swarm optimisation (PSO) algorithm embedded grey simulation technique is designed in this paper.
