This paper aims to enhance the reliability of self-validating multifunctional sensors.

Abstract

Purpose

This paper aims to enhance the reliability of self-validating multifunctional sensors.

Design/methodology/approach

An effective fault detection, isolation and data recovery (FDIR) strategy by using kernel principal component analysis (KPCA) coupled with gray bootstrap and fault reconstruction methods.

Findings

The proposed FDIR strategy is able to the address fault detection, isolation and data recovery problem of self-validating multifunctional sensors efficiently.

Originality/value

A KPCA-based model which can overcome the limitation of existing linear-based models is used to achieve the fault detection task. By using gray bootstrap method, the position of all faulty sensitive units can be calculated even under the multiple faults situation. A reconstruction-based contribution method is adopted to evaluate the amplitudes of the fault signals, and the fault-free output of the faulty sensitive units can be used to replace the fault output.

Abstract

Purpose

The study aims to understand how cultural route heritage is conceptualized and managed in China by systematically reviewing the research literature on Chinese cultural route heritage (CRH). The study intends to inspire further discussion on the theoretical and practical development of cultural routes since the development is still at a liminal stage in China.

Design/methodology/approach

A total of 253 research articles related to Chinese cultural rote heritage from major Chinese and English research databases China National Knowledge Infrastructure (CNKI), Web of Science (WOS) and Scopus have been comprehensively identified and reviewed for the purpose of the study.

Findings

Four major themes of research on Chinese CRH have been identified: conceptual evaluation, list of the routes and characteristics of the routes, conservation and utilization. The results revealed that China has very rich resources in CRH, many of which were formed a long time ago, which exist across vast geographic regions and have assumed multiple functions and undergone dynamic reciprocal exchanges among diverse cultures and ethnicities.

Practical implications

The paper summarizes some major obstacles faced by CRH in China and proposes a strategic model to address the need for a more sustainable development of CRH in the Chinese context.

Originality/value

The paper offers a comprehensive overview of CRH in China and discusses practical issues in management and development of heritage great in size, number and complexity.

Abstract

Study level/applicability

This case is suitable for undergraduates, MBA students and students from business administration departments in the teaching of human resources management and performance management.

Case overview

Luodian Electric Power Construction Corporation Group (LEPCC Group) is a state owned enterprise transformed from a construction unit of Luopu Power Supply Bureau (LPSB), a governmental organization in charge of all the electricity supply in Luopu City. The general manager of LEPCC, Gu Ming tried to set up a modern market-oriented management system for LEPCC. Unfortunately the problems that had accumulated in the past two decades during which LEPCC was a governmental organization made his reforms very difficult. The first headache for Gu Ming was the performance appraisal reform in LEPCC. The existing performance appraisal system seemed to have at least three problems in practice: unclear appraisal objectives, an improper assessment system, a different appraisal standard for similar positions. What should Gu Ming do to build a proper performance appraisal system to help the fast-growing LEPCC Group to make LEPCC a competitive market-oriented player?

Expected learning outcomes

The first objective of this case is to enable students to understand that the issues of working performance are issues of people first, rather than issues of the management system. If the management focuses on the system instead of on the staff of the company to design the performance management system, the system will be fruitless and inefficient. The second objective is to cultivate students' capability to apply the basic theories of human resource management and the knowledge of performance appraisal in case analysis and practical management. This case, seemingly about performance appraisal, is in fact about the organizational structure and processes of the organization. Reform should start with organizational analysis, job analysis and job descriptions. Only when all these have been done correctly, can the performance management system be designed more reasonably, scientifically and efficiently.

Abstract

We make use of the Volunteered Geographic Information (VGI) data to extract the total extent of the roads using remote sensing images. VGI data is often provided only as vector data represented by lines and not as full extent. Also, high geolocation accuracy is not guaranteed and it is common to observe misalignment with the target road segments by several pixels on the images. In this work, we use the prior information provided by the VGI and extract the full road extent even if there is significant mis-registration between the VGI and the image. The method consists of image segmentation and traversal of multiple agents along available VGI information. First, we perform image segmentation, and then we traverse through the fragmented road segments using autonomous agents to obtain a complete road map in a semi-automatic way once the seed-points are defined. The road center-line in the VGI guides the process and allows us to discover and extract the full extent of the road network based on the image data. The results demonstrate the validity and good performance of the proposed method for road extraction that reflects the actual road width despite the presence of disturbances such as shadows, cars and trees which shows the efficiency of the fusion of the VGI and satellite images.

Abstract

As a result of the new reform of the college curriculum in China in 1998, the previously separated five information‐related majors were merged into a new special “information management and systems” curriculum. This change brings about both new challenges and new threats to the old information science specialism. However, it is inevitable for the specialism to change itself.

Abstract

Purpose

45 steel is a common material for the manufacture of various components such as shafts or gears. However, its poor surface properties often limit its applications. The purpose of this paper is to find a way to enhance the surface performance of 45 steel, which is expected to improve the wear resistance of 45 steel.

Design/methodology/approach

Double glow plasma surface metallurgy technique was used to prepare hafnium carbide (HfC) coatings on the surface of the 45 steel with two preparation process; one is to diffuse two elements together, while the other is to diffuse step by step. The scanning electronic microscopy and the X-ray diffraction were used to analyze the morphology and phase of the HfC coatings. And then the wear tests were carried out for this coating.

Findings

Coating diffused step by step shows better performance; it has a 15-µm alloyed layer which is uniform and dense and its hardness can reach up to 1326.5 Vickers-hardness (HV). While the coating fabricated by diffusing elements together owns a 10-µm alloyed layer and its hardness is 1204.1 HV. According to the wear test results, both coatings have a protective effect on the substrate and the coating prepared by step-by-step diffusion process has less wear volume, indicating that it possesses better friction reduction.

Originality/value

A new method which diffuses elements together was successfully used to prepare compound HfC coating, which can reduce the cost of coating preparation and improve the efficiency of coating preparation.

Abstract

Purpose

Building on social informational processing theory, the purpose of this paper is to develop and test a theoretical model of moderated mediation in which social loafing tendency serves as an intervening mechanism that explains associations among two dimensions of leader–member relationships (formal and informal relationships, namely, leader–member exchange and leader–member guanxi) and customer service performance.

Design/methodology/approach

The authors designed a field study to test the hypotheses presented in this paper. A survey of 304 supervisor–employee pairs and matched customers generally provide support for this model.

Findings

The authors found that social loafing tendency played a mediating role between leader–member relationships and customer service performance. Co-worker service-oriented OCB moderated the positive relationship between leader–member guanxi and loafing tendency.

Research limitations/implications

More samples should be collected from both private and state-owned company. Both the informal and formal leader–member relationships should be unanimously included in examining how the leader–member relationships influence focal employee’s attitude and behavior, particularly in societies where the informal relationship plays noticeable role.

Practical implications

Managers should properly deal with formal and informal relationship with subordinates.

Originality/value

The influence of leader–member guanxi on employees and organization is controversial in extant literature. In some sense, this finding contributes to extant literature by further clarifying the influence of guanxi on the focal employee’s performance.

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.
