Business interactions are increasingly crossing boundaries. Boundary crossing is a process of joining or parting people. Negotiation is the media of this process. This paper is an attempt to bridge the boundaries of strategic business negotiation, communication and emotion in a cross-cultural context. In particular, we argue that miscommunications are ‘boundary crossing mishaps’. Such mishaps are affected by negotiators’ understanding of the respective cultures of the parties, negotiation skill, affective cultural background of the parties, cultural differences, emotional awareness and regulation, negative affect and discrepancy in convergence divergence between the interactants. When too many of these hassles or mishaps occur, negotiation breaks down. In this way, it is the accumulation of many little things, many little misunderstandings, that break negotiation.

Cross-linked poly(ethylene glycol) diacrylate (PEGDA) membranes were prepared by polymerization in periodic nanostructured lyotropic liquid crystals (LLC) hexagonal phases under UV light. A series of membranes were prepared under different purification treatment conditions. Polarized light microscope was employed to determine the LLC phase texture of LLC system before and after polymerization. It is found that the LLC hexagonal structure retained to some degree after polymerization. The interior structures of final membranes were investigated with scanning electron microscope (SEM). The results suggested that purification process affect the structure retention.

This thesis is based on fieldwork I carried out between December 1987 and June 1989 while living with the residents of a small Warlpiri Outstation Community situated ca. 75 km north-west of Tennant Creek in the Northern Territory of Australia. Colonialism is a process whereby incommensurate gender regimes impact differently on women and men and this is reflected in the indigenous response which affects the socialization of Western things. The notion of the indigenous KIRDA-KURDUNGURLU reciprocity is shown to be consistent with a gender system and to articulate all exchange relations as pro-creative social relationships. This contrasts with the Western capitalist system of production and social reproduction of gendered individuals in that it does not ascribe gender to biological differences between women and men but is derived from a land based social division between Sister-Brother. Social relationships are put under great strain in an effort to socialize Western things for Warlpiri internal use, I argue that the colonization of Aboriginal societies is an ongoing process. Despite the historical shift from a physical all-male frontier to the present day cross-cultural negotiations between Aborigines and Non-Aborigines, men still privilege men. The negotiation process for ownership of a Community Toyota is the most recent phenomenon where this can be observed. Male privilege is established by linking control over the access to the Community Toyota with traditional rights to land. However, the Toyota as Western object has a Western gender identity as well. By pitting women against men it engages people in social conflict which is brought into existence through an organisation of Western concepts based on an alien gender regime. But Western things, especially the Community Toyota, resist socialization because the Warlpiri do not produce these things. Warlpiri people know this and, to satisfy their need for Western things, they engage them in a process of social differentiation. By this process they can be seen actively to maintain the Western system in an effort to maintain themselves as Warlpiri and to secure the production of Western things. This investigation of the cultural response to Western influences shows that indigenous gender relations are only maintained through a socially stressful process of socializing Western things.

This article discusses the recruitment and training of bilingual project workers and their role in data gathering; the level of comprehension of the interviewees with regard to the nature of the task and its alien nature; the contribution of social customs and expectations; the vagaries of language; the researchers' level of comprehension of data collected across a range of languages; the feelings of loss of control by the researchers over the research process; and issues of communication with bilingual project workers. The authors draw on two studies designed to assess the adequacy of questionnaire translations from English into four ethnic minority languages: Cantonese, Punjabi, Urdu and Sylheti. Bilingual project workers were recruited to carry out interviews and focus groups with the lay communities and to feed back results in English to the researchers. The authors conclude that researchers should be aware of the influence of social and contextual factors when carrying out research with ethnic minority participants mediated by bilingual project workers.

Increasingly, the linear, instrumentalist and culturally hegemonic character of dominant sustainability discourse is under critique, with the term accruing new or expanded associations that challenge the its future-oriented, temporally stable, and ontologically determinate history. In Australia, these shifts take in a recognition that indigenous Australian understandings of and relationships with the environment profoundly challenge the generic claims of sustainability applied to both theory and practice. But how do these radically different and still marginal understandings actually enter into the process of producing sustainable designs on the world? This paper will report on the beginnings of a collaborative project that seeks to advance a proposal for an Aboriginal cultural precinct in the heart of Melbourne. This project's intention is to develop innovative methods for consultation and participation through collaborative creative research between Aboriginal artists and academic architects. The paper will discuss this method as a strategy for moving beyond traditional modes of cross-cultural engagement in the design and construction of sustainable cultural precincts.

Despite the fundamental and administrative difficulties associated with cross-cultural research the rewards are significant and, given an increasing trend toward globalisation, the move away from singular location studies to more comparative research is to be encouraged. In order to facilitate this research process it is imperative, however, that considerable attention is given to the methodological issues that can beset cross-cultural research, specifically as these issues relate to the primary domain or discipline of investigation, which in this instance is research on business ethics. Utilising the experience of a four country comparative study of both Asian and Western cultures in the field of business ethics, the following presents a discussion of methodological concerns under the three broad areas of operationalising culture, operationalising business ethics, and data interpretation.

Much of the current academic and policy literature on gender and inclusive education calls for schools and teachers to move towards understanding gender as a multidimensional process of negotiated social relations that is informed by a range of discursive practicesbut how students themselves can conceptualize gender relations in these ways is under researched. This paper reports on an aspect of an exploratory study that had as its focus students' perceptions of cross-cultural and cross-gender friendships. This project, funded by a small Australian Research Council grant from La Trobe University, began with surveys of Year 10 students at two schools who have previously participated in gender reform projects. Those students who indicated they had cross-category friendships were then interviewed to elicit narratives that depict their perspectives on these friendships.

Ageing can lead to the degradation of the tensile properties of natural rubber. The ageing process causes changes in the polymer segmental motion as well as the chemical structure, both of which can be monitored using nuclear magnetic resonance (NMR) spectroscopy. This work demonstrates that NMR can quantify rubber degradation due to ageing, and also that relatively simple NMR equipment can be used. This simpler equipment can be made portable and so could give a simple and fast indication of the condition of rubber in service. The 1H NMR transverse relaxation time, T2, and the 13C NMR spectrum using cross polarization and magic angle spinning (CP MAS) for samples taken at various levels of a degraded natural rubber liner were compared. These experiments showed that, as the level of degradation increased, the 1H NMR transverse relaxation time decreased. The 13C spectra showed considerable peak broadening, indicative of decreased mobility with increased level of degradation as well as the presence of degradation products. Further investigations using lower powered NMR equipment to measure the 1H NMR transverse relaxation times of two different series of natural rubbers were also performed. This work has shown that this simpler method is also sensitive to structural and mechanical property changes in the rubber. This method of monitoring rubber degradation could lead to the non-destructive use of NMR to determine the condition of a part in service.

Variation in the incoming sheet material and fluctuations in the press setup is unavoidable in many stamping plants. The effect of these variations can have a large influence on the quality of the final stamping, in particular, unpredictable springback of the sheet when the tooling is removed. While stochastic simulation techniques have been developed to simulate this problem, there has been little research that connects the influence of the noise sources to springback. This paper characterises the effect of material and process variation on the robustness of springback for a semi-cylindrical channel forming operation, which shares a similar cross-section profile as many automotive structural components. The study was conducted using the specialised sheet metal forming package AutoFormTM Sigma, for which a series of stochastic simulations were performed with each of the noise sources incrementally introduced. The effective stress and effective strain scatter in a critical location of the part was examined and a response window, which indicates the respective process robustness, was defined. The incremental introduction of the noise sources allows the change in size of the stressstrain response window to be tracked. The results showed that changes to process variation parameters, such as BHP and friction coefficient, directly affect the strain component of the stressstrain response window by altering the magnitude of external work applied to forming system. Material variation, on the other hand, directly affected the stress component of the response window. A relationship between the effective stressstrain response window and the variation in springback was also established.

This paper explores the dance of trust in cross-sector R&D collaborations, and does so by drawing on a multi-method study (involving qualitative research, case studies and a survey of project leaders) of the Australian Cooperative Research Centre (CRC) Program. R&D collaborations formed under this Program involve two main types of risk, venture or performance-related and relational, and these are problematic given power, information and risk impact asymmetries among the partners. Within the CRCs these risks are addressed through formalisation, employing the “right people”, and through relationship building. Trust (theorised following Sako as a multi-dimensional construct) is central to these processes. Where trust is formed among CRC participants, and is reinforced over repeated interactions, then relational and performance risks cease to become a major concern for CRC managers. In the CRCs, trust is formed and sustained as a multi-level process. Engagement and relationship commitment is achieved at an organizational level, and partner reputation, credible commitments and the institutional context are important factors here. At the project level, trust, in conjunction with a task focus, leads to a positive collaboration experience and this is associated with positive project outcomes. Within CRC projects, capabilities for communication and cross-sector management are important for the formation and maintenance of trust. The paper concludes by discussing the managerial implications of the study’s findings and by identifying areas for further research and conceptual development.

This paper examines cross-sector engagement by drawing on a case study of a successful R&D project which involved an Australian Cooperative Research Centre (with CSIRO as a partner), and the eyecare products company Ciba Vision. This project resulted in the market launch of an extended wear contact lens, a break-through product. The engagement process moved through two phases. In an initiation phase, partner reputation and the potential for complementary resources were important in the partnering decision. In an engagement phase, the partners built a relationship and focused on the tasks to be completed. In doing so, they made a number of credible commitments to the venture (most notably to jointly assign project intellectual property between the public and private sector partners), developed a trusting relationship, adopted a disciplined and effective project management approach, learned the capability for cross-sector collaboration management, and put much effort into fostering communication to facilitate team building and the task focus. The management approach taken lead to a positive experience of the project among the partners, and this was positively associated with tangible project outcomes. Such collaborations may persist across projects, but in a disengagement phase negotiations on the conditions of exit may be required. It is concluded that to build a successful cross-sector collaboration requires interpersonal engagement within and across the organizations involved.

Virtual and physical prototypes play a significant role in the design of artifacts. This is particularly true in cross-functional team collaboration, where diverse disciplines come together to contribute to the concept, design and development of an artifact. While the role of prototyping in design and cross-functional collaboration has been widely studied independently, little is known of the role that physical prototypes play during cross-functional team collaboration. This paper reports on a study of virtual and physical prototyping strategies used by a cross-functional team comprising engineers and designers working on a concept car project. The paper provides a background of the collaborative design process and details the role of physical prototyping methods during the design of the concept car.

Retaining hexagonal lyotropic liquid crystal (LLC) structures in polymers after surfactant removal and drying is particularly challenging, as the surface tension existing during the drying processes tends to change the morphology. In this study, cross-linked poly(ethylene glycol) diacrylate (PEGDA) hydrogels were prepared in LLC hexagonal phases formed from a dodecyltrimethylammonium bromide (DTAB)/water system. The retention of the hexagonal LLC structures was examined by controlling the surface tension. Polarized light microscopy, X-ray diffraction and small angle X-ray scattering results indicate that the hexagonal LLC structure was successfully formed before polymerization and well retained after polymerization and after surfactant removal when the surface tension forces remained neutral. Controlling the surface tension during the drying process can retain the nanostructures templated from lyotropic liquid crystals which will result in the formation of materials with desired nanostructures.
