Abstract

Purpose

In response to the issue of traditional algorithms often falling into local minima or failing to find feasible solutions in manipulator path planning. The purpose of this paper is to propose a 3D artificial moment method (3D-AMM) for obstacle avoidance for the robotic arm's end-effector.

Design/methodology/approach

A new method for constructing temporary attractive points in 3D has been introduced using the vector triple product approach, which generates the attractive moments that attract the end-effector to move toward it. Second, distance weight factorization and spatial projection methods are introduced to improve the solution of repulsive moments in multiobstacle scenarios. Third, a novel motion vector-solving mechanism is proposed to provide nonzero velocity for the end-effector to solve the problem of limiting the solution of the motion vector to a fixed coordinate plane due to dimensionality constraints.

Findings

A comparative analysis was conducted between the proposed algorithm and the existing methods, the improved artificial potential field method and the rapidly-random tree method under identical simulation conditions. The results indicate that the 3D-AMM method successfully plans paths with smoother trajectories and reduces the path length by 20.03% to 36.9%. Additionally, the experimental comparison outcomes affirm the feasibility and effectiveness of this method for obstacle avoidance in industrial scenarios.

Originality/value

This paper proposes a 3D-AMM algorithm for manipulator path planning in Cartesian space with multiple obstacles. This method effectively solves the problem of the artificial potential field method easily falling into local minimum points and the low path planning success rate of the rapidly-exploring random tree method.

Abstract

Purpose

The aim of this paper is to adopt a study framework of network embeddedness and social capital perspective, and to explore the relationship among relationship strength, knowledge integration capability and the efficiency of knowledge transfer among technology alliance.

Design/methodology/approach

Empirical data were acquired through a recent survey of electrical and mechanical, biopharmaceutical and chemical industries. LISREL analysis was employed to examine the impact of relationship strength and integration capability on the efficiency of knowledge transfer.

Findings

The results verify that relationship strength has a significant positive impact on cooperative knowledge transfer and external integration capability, but it cannot influence innovative knowledge and internal integration capability. The internal knowledge integration capacity has a positive influence on the external integration capacity, but the external knowledge integration does not have significant impact on the internal integration capacity. Combined with the external integration capability, relationship strength's indirect influence on cooperative knowledge transfer is greater than the direct one.

Research limitations/implications

Strengthening knowledge integration capacity is the key to improve the efficiency of knowledge transfer by taking advantage of partnerships. The enterprise should adjust the relationship strength according to the function matching of the knowledge.

Originality/value

This paper is one of very few that provide empirical evidence of the impact of relationship strength and integration capability on the performance of knowledge transfer. It provides necessary basis for the enterprise to lay out and establish the technology alliance, which the enterprise should adjust the type of union according to the characteristic of the knowledge during the process of planning the technology alliance. This paper also suggests that the enterprises should make full use of technology alliance to enhance the external integration ability.

Abstract

Logistical facility location decisions can make a crucial difference in the success or failure of a company. Geographical Information Systems (GIS) have recently become a very popular decision support system to help deal with facility location problems. However, until recently, GIS methodologies have not been fully embraced as a way to deal with new facility location problems in business logistics. This research makes a framework for categorizing empirical facility location problems based on the intensity of the involvement of GIS methodologies in decision making. This framework was built by analyzing facility location models and GIS methodologies. The research results revealed the depth of the embracement of GIS methodologies in logistics for determining new facility location decisions. In the new facility location decisions, spatial data inputs are almost always coupled with the visualization of the problems and solutions. However, the usage of GIS capability solely (i.e. suitability analysis) for problem solving has not been embraced at the same level. In most cases, the suitability analysis is used together with special optimization models for choosing among the multiple alternatives.

This study aims to explore how a Chinese lesson study (LS) supports a teacher's learning of transforming curriculum reform ideas into classroom practices.

Abstract

Purpose

This study aims to explore how a Chinese lesson study (LS) supports a teacher's learning of transforming curriculum reform ideas into classroom practices.

Design/methodology/approach

Data analyzed in this study included lesson plans, three videotaped research lessons, three audio-taped group meetings, interviews, the teacher's reflection journals and other related materials. Clarke and Hollingsworth's interconnected model of professional growth (IMPG) was adopted as the theoretical and analytical framework for examining the teacher's learning process.

Findings

This study found that teachers can deepen their understanding of innovative curriculum ideas and implement them through an iterative cycle of planning, enactment and reflection in LS. Involving knowledgeable others in the process and reflecting on evidence-based evaluation of students' learning outcomes is crucial for changing the teacher's knowledge, beliefs, attitudes and teaching practices. Theoretical tools, such as learning trajectory, are useful for transforming curriculum reform ideas that teachers find abstract and overly broad into concrete and actionable lesson designs.

Originality/value

Theoretically, this study can broaden our knowledge about how the under-studied mechanism of Chinese LS can contribute to helping teachers to transform reform ideas into classroom practices. Practically, this study provides suggestions for researchers and educators to reflect on and improve the effectiveness of teachers' professional development programs in a reform context.

Abstract

This chapter investigates the behavior of Reddit’s news subreddit users and the relationship between their sentiment on exchange rates. Using graphical models and natural language processing, hidden online communities among Reddit users are discovered. The data set used in this project is a mixture of text and categorical data from Reddit’s news subreddit. These data include the titles of the news pages, as well as a few user characteristics, in addition to users’ comments. This data set is an excellent resource to study user reaction to news since their comments are directly linked to the webpage contents. The model considered in this chapter is a hierarchical mixture model which is a generative model that detects overlapping networks using the sentiment from the user generated content. The advantage of this model is that the communities (or groups) are assumed to follow a Chinese restaurant process, and therefore it can automatically detect and cluster the communities. The hidden variables and the hyperparameters for this model are obtained using Gibbs sampling.

Abstract

Purpose

This paper aims to make a systematic study on the factors that hinder the development of China’s intelligent automobile manufacturing industry; based on comprehensive understanding of these obstacles and by optimization means, ultimately, the healthy and sustainable development of intelligent automobile manufacturing industry in China can be promoted.

Design/methodology/approach

Based on a questionnaire survey of intelligent automobile manufacturing listed companies in China, first, fuzzy semantic scale was adopted to collect respondents’ choices, the fuzzy score function is used to calculate the fuzzy score value and these data are used as the basis for subsequent model analysis. Then, structural equation modeling (SEM) was adopted to analyze the causal relationship between influencing factors to explore the main hinder factors.

Findings

It is found that, in the short term, the backwardness of technological industrialization is the main reason leading to low permeability of intelligent automobile; in the medium term, the imperfect industrial R&D ability and the insufficiency of infrastructure are major causes for high manufacturing cost and low competitiveness of intelligent automobile manufacturing industry; in the long term, the lack of national policy and industrial strategic planning is the main factors affect intelligent automobile manufacturing cost and the industry competitiveness.

Practical implications

The research conclusion has important policy implications for promoting intelligent automobile manufacturing sustainable development. In recent years, China’s intelligent automobile manufacturing industry has gradually stepped out of breeding period; therefore, the role of government should be gradually transformed from participants to managers and regulators. Considering the fact that intelligent automobile cost is very high, and still higher than the cost of fuel vehicle, government should focus on the issues such as improving R&D capabilities, infrastructure construction, policy framework system, legal system and technological industrialization. Specifically, in short-term planning, improving technological industrialization level is the key to development; in medium-term planning, policymakers should focus on the improvement of R&D capabilities and infrastructure; considering the long-term development, establishing appropriate national policies and dealing with the adverse impact of imperfect strategic planning are the most sensible choice.

Originality/value

This paper analyzes the factors that hinder the development of China’s intelligent automobile manufacturing industry for the first time, and provides the basic logic of integration factors at different levels with the development of intelligent automobile to reveal the uniqueness and facts of China’s economic development.

Abstract

Employing expatriates who share an ethnicity with host country employees (HCEs) is a widespread expatriate selection strategy. However, little research has compared how expatriates and HCEs perceive this shared ethnicity. Drawing upon an identity perspective, we propose HCEs' ethnic identity confirmation, the level of agreement between how an HCE views the importance of his/her own ethnic identity and how expatriates view the importance of the HCE's ethnic identity, affects HCEs' attitudes toward ethnically similar expatriates. Results of two experiments show that HCEs' ethnic identity confirmation is related to HCEs' perception of expatriates' trustworthiness and knowledge-sharing intention.

Abstract

Purpose

The purpose of this paper is to explore the means for enhancing the image and business legitimacy of a socially discredited industry – pawnbroking in pre-1949 China – are explored. Previous studies suggest companies operating within such industries cannot solely rely on hard marketing strategies “to maximize sales and profits as they do with soaps and shoes” (Davidson, 2003, p. 7). Instead, they must find soft strategies for improving company and industry image and legitimacy.

Design/methodology/approach

This research relies on qualitative analysis of historical data and documents.

Findings

Soft strategies deployed by Chinese pawnbrokers – such as interpretations, moral value advocacies and institutionalized arrangements – contributed substantially to improving pawnbroking’s image and business legitimacy.

Research limitations/implications

Interconnections among ethical values, image, business legitimacy and select marketing strategies are clarified. The efficacy of historically analyzing previously implemented business strategies and their embedding contexts is discussed.

Practical implications

Strategies Chinese pawnbrokers used to mitigate their previously negative image and boost their business legitimacy suggest strategies current socially disapproved companies can use to improve their image and business legitimacy.

Originality/value

A historical analysis of pre-1949 Chinese pawnbroking can suggest soft marketing strategies for overcoming consumers’ negative company and industry impressions.
