This paper introduces a generic performance measurement methodology for identifying and dimensioning the user requirements of laboratory information systems with a view to evaluating and improving their overall user satisfaction. The dynamic Web‐based laboratory information system (known as IntraMEL) for the Manufacturing Engineering Laboratories (MEL) in the City University of Hong Kong is used as a case study for formulating, testing and implementing the methodology. The proposed model takes an analytical approach to assess the performance of an information system using psychometric concepts. Through the experience gained from applying the methodology on IntraMEL, a set of performance evaluation guidelines can be established. These evaluation guidelines will be applicable to the information systems in other laboratories and service centres.

Almost all industrial systems are distributed with multiple control points which interact to a limited extent, for which the idea of distribution of task at local (field) level is emerging. As locally‐based application tasks can reduce control delays, a fieldbus‐based smart and reliable DCS solution is recognised as a leader for real‐time industrial automation. Advanced control system has turned itself towards the implementation of digital distributed control systems (DCS) from centralised control systems. The phenomenon is becoming very popular because of its advantages over the whole operating system. Presents a case study for realising manufacturing systems (production lines) with fieldbus technology. The local operating network (LON) fieldbus system was chosen for this purpose because of availability of a wide range of products. Emphasises the reliability aspects of the control systems. A representative of a conveyor system, integrated with field devices, was conceived as the target platform.

A flexible manufacturing system (FMS) is a complex manufacturing system and it demands a robust control software for its scheduling, planning and control functions. This paper describes the development of an agent‐based infrastructure for the control of a cellular FMS. The FMS in this project is a flexible assembly cell (FAC), comprising two assembly robots and a conveyor system. The aim is to establish a multi‐agent control system with good expandability and to be able to cope with dynamic changes in the FAC. The proposed agent‐based FAC control system comprises a collection of agents implemented in a distributed control network. The approach of the agent design is based on the object‐oriented modelling technique. According to the proposed control architecture, a standard agent template has been designed for the establishment of individual agents in the agent‐based system.

Knowledge‐based timed colored object‐oriented Petri net (KTCOPN) is presented as a modelling method for a reconfigurable assembly system (RAS) in this paper. Compared to the conventional flexible assembly systems, the configuration of a RAS will allow flexibility not only in assembling a variety of products, but also in changing the system itself. Combining knowledge and object‐oriented methods into timed colored Petri net, allow the characteristic of RAS to be fully expressed. With object‐oriented methods, the whole system can be decomposed into concrete objects explicitly, and their relationship is constructed according to the system assembly requirements. Finally, a simple assembly system modeled by the KTCOPN is given.

Rural Australian patients continue to receive inadequate medical attention. One potential solution to this is to train Indigenous Australians to become medical doctors and return to their community to serve their people. The study aims to examine whether Indigenous medical students have a stronger intention to practice in underserved communities.
A sample of Indigenous (N = 17) and non-Indigenous students (N = 188) from a medical program in Sydney was surveyed about their medical self-concept and motivation. Confirmatory factor analysis (CFA) was conducted, group differences were tested, and correlation patterns were examined.
CFA found seven distinct factors – three medical self-concepts (affective, cognitive, and cultural competence), one motivation factor, and three work-related variables – intention to serve underserved communities (intention), understanding of Indigenous health (understanding), and work-related anxiety (anxiety). Indigenous medical students were higher in cultural competence, intention, and understanding. Both the affective and cognitive components of medical self-concept were more highly correlated with intention and understanding for Indigenous students than for non-Indigenous students.
It is important to examine medical students’ self-concepts as well as their cultural characteristics and strengths that seed success in promoting service to underserved Indigenous communities.
The findings show that Indigenous medical students tended to understand Indigenous health issues better and to be more willing to serve underserved Indigenous communities. By enhancing both the affective and cognitive components of medical self-concepts, the “home-grown” medical education program is more likely to produce medical doctors to serve underserved communities with a good understanding of Indigenous health.

The purpose of this paper is to critically evaluate the state of the art of applications of organisational systematics and manufacturing cladistics in terms of strengths and weaknesses and introduce new generic cladistic and hierarchical classifications of discrete manufacturing systems. These classifications are the basis for a practical web-based expert system and diagnostic benchmarking tool.
There were two stages for the research methods, with eight re-iterative steps: one for theory building, using secondary and observational data, producing conceptual classifications; the second stage for theory testing and theory development, using quantitative data from 153 companies and 510 manufacturing systems, producing the final factual cladogram. Evolutionary relationships between 53 candidate manufacturing systems, using 13 characters with 84 states, are hypothesised and presented diagrammatically. The manufacturing systems are also organised in a hierarchical classification with 13 genera, 6 families and 3 orders under one class of discrete manufacturing.
This work addressed several weaknesses of current manufacturing cladistic classifications which include the lack of an explicit out-group comparison, limited conceptual cladogram development, limited use of characters and that previous classifications are specific to sectors. In order to correct these limitations, the paper first expands on previous work by producing a more generic manufacturing system classification. Second, it describes a novel web-based expert system for the practical application of the discrete manufacturing system.
The classifications form the basis for a practical web-based expert system and diagnostic benchmarking tool, but also have a novel use in an educational context as it simplifies and relationally organises extant manufacturing system knowledge.
The research employed a novel re-iterative methodology for both theory building, using observational data, producing the conceptual classification, and through theory testing developing the final factual cladogram that forms the basis for the practical web-based expert system and diagnostic tool.
Since China initiated its “go global” policy that promotes its overseas investment, China’s Outward Foreign Direct Investment (OFDI) has increased almost twenty times during the last 10 years, reaching $55.9 billion in 2008. The issue of internationalization of Chinese OFDI has attracted increasing attention of researchers from a business perspective. This article systematically reviews the previous studies on overseas investments by Chinese MNEs and discusses the characteristics of Chinese internationalization behavior at both firm level and country level. The internationalization of Chinese companies cannot be understood as a simple game of “catch up” with established MNEs, and more firm‐level empirical studies should be carried out on how these characteristics influence firms’ strategic decisions.

We examine the mode of international expansion as an equilibrium governance contract between home country and host country factor owner. The focus is on agency costs, a form of transactions costs. Two phenomena are shown to be related to the agency costs imposed by factor owners: (i) the choice of different modes of international expansion by one firm in different locations, and (ii) the simultaneous occurrence of several forms of foreign involvement in the same location. We attempt to characterize the dynamic relationship between the mode of an offshore operation and changes in factor market conditions that affect agency costs.

The objective of this study is to investigate how country risk, different political actions from the government and bureaucratic behavior influence the activities in industry supply chains (SCs) in emerging markets. The main objective of this study is to investigate the influence of these external stakeholders’ elements to the demand-side and supply-side drivers and barriers for improving competitiveness of Ready-Made Garment (RMG) industry in the way of analyzing supply chain. Considering the phenomenon of recent change in the RMG business environment and the competitiveness issues this study uses the principles of stakeholder and resource dependence theory and aims to find out some factors which influence to make an efficient supply chain for improving competitiveness. The RMG industry of Bangladesh is the case application of this study. Following a positivist paradigm, this study adopts a two phase sequential mixed-method research design consisting of qualitative and quantitative approaches. A tentative research model is developed first based on extensive literature review. Qualitative field study is then carried out to fine tune the initial research model. Findings from the qualitative method are also used to develop measures and instruments for the next phase of quantitative method. A survey is carried out with sample of top and middle level executives of different garment companies of Dhaka city in Bangladesh and the collected quantitative data are analyzed by partial least square-based structural equation modeling. The findings support eight hypotheses. From the analysis the external stakeholders’ elements like bureaucratic behavior and country risk have significant influence to the barriers. From the internal stakeholders’ point of view the manufacturers’ and buyers’ drivers have significant influence on the competitiveness. Therefore, stakeholders need to take proper action to reduce the barriers and increase the drivers, as the drivers have positive influence to improve competitiveness.
This study has both theoretical and practical contributions. This study represents an important contribution to the theory by integrating two theoretical perceptions to identify factors of the RMG industry’s SC that affect the competitiveness of the RMG industry. This research study contributes to the understanding of both external and internal stakeholders of national and international perspectives in the RMG (textile and clothing) business. It combines the insights of stakeholder and resource dependence theories along with the concept of the SC in improving effectiveness. In a practical sense, this study certainly contributes to the Bangladeshi RMG industry. In accordance with the desire of the RMG manufacturers, the research has shown that some influential constructs of the RMG industry’s SC affect the competitiveness of the RMG industry. The outcome of the study is useful for various stakeholders of the Bangladeshi RMG industry sector ranging from the government to various private organizations. The applications of this study are extendable through further adaptation in other industries and various geographic contexts.
