A Distributed Object Model for CSCW in the Construction Industry

Information about products for the construction industry is increasingly often provided to designers in digital ways that enable them to apply the information directly in the design process. Digital product catalogues are provided using various media and formats and several initiatives are taken by the industry and by CAD developers to integrate this kind of information into CAD systems. Generally, current practice is to distribute the information to designers, for example, by using CD-ROMs or a website where the information can be downloaded. In our research we recognise that distributing information in this manner detaches it from the business processes in the construction supply chain, which is a major disadvantage. The project presented in this paper concerns the implementation in the Dutch construction industry of a methodology for sharing product information through a distributed object model. The methodology, which is called Concept Modelling, forms a generic basis for the support of collaborative design, but is applied in this project to the integration of information from the supply chain in the design process. Through the distributed object model, design information and product information can be integrated while the actual data objects remain at their source. This enables the supply chain to provide information of a high semantic level to designers while keeping the control over the information and maintaining the relationship of the information with their business processes. The advantages of this approach in which information is shared, rather than exchanged, are numerous. Redundancy of information is minimised, consistency is improved, and updated information is available immediately. Moreover, design and construction processes can benefit significantly from the dynamic aspects of accessing information that is tied to business processes in the supply chain. For example, product selection during design can be based on latest information on product details, prices, production methods, and variants of products. This information can be provided to designers automatically and on demand

A study of the adjustment of Western expatriates in Taiwan ROC with the Multicultural Personality Questionnaire (MPQ)

The present paper examined the validity of the Multicultural Personality Questionnaire (MPQ). As criteria of validity three levels of adjustment were used. The study took place among a sample of expatriates (N = 102) during their assignment in Taiwan. The MPQ has scales for cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. The MPQ-scales appeared to be positively related to expatriates' personal, professional and social adjustment. In all three domains, emotional stability appeared most consistently as predictor of adjustment. Social initiative was an additional strong predictor of psychological well-being, and so was cultural empathy of satisfaction with life and of the amount of social support in the host country. Flexibility was a predictor of job satisfaction and social support. The study also examined the effects of marital status on adjustment. Married expatriates showed higher levels of adjustment than expatriates who were single or separated

Distributed object models for collaboration in the construction industry

Abstract Information about products for the construction industry is increasingly often provided to designers in digital ways that enable them to apply the information directly in the design process. Digital product catalogues are provided using various media and formats and several initiatives are taken by the industry and by CAD developers to integrate this kind of information into CAD systems. Generally, current practice is to distribute the information to designers, for example, by using CD-ROMs or a website where the information can be downloaded. In our research, we recognise that distributing information in this manner detaches it from the business processes in the construction supply chain, which is a major disadvantage. The project presented in this paper concerns the implementation in the Dutch construction industry of a methodology for sharing product information through a distributed object model. The methodology, which is called Concept Modelling, forms a generic basis for the support of collaborative design, but is applied in this project to the integration of information from the supply chain in the design process. Through the distributed object model, design information and product information can be integrated while the actual data objects remain at their source. This enables the supply chain to provide information of a high semantic level to designers while keeping the control over the information and maintaining the relationship of the information with their business processes. The advantages of this approach in which information is shared, rather than exchanged, are numerous.

The multicultural personality questionnaire: Reliability and validity of self- and other ratings of multicultural effectiveness.

The present study considered the reliability and validity of the 78-item revised version of the Multicultural Personality Questionnaire, a multidimensional instrument aimed at measuring multicultural effectiveness among two student samples (N = 210). Exploratory and confirmatory factor analyses on self- and other ratings for an original set of 138 items revealed five reliable factors underlying the questionnaire: Cultural Empathy, Openmindedness, Emotional Stability, Social Initiative, and Flexibility. In addition, initial support for the validity of the instrument was obtained by showing convergence between self and other ratings on the scales. Moreover, the instrument was clearly able to discriminate between students with and without explicit international inspirations. The dimension of Cultural Empathy was least well supported
