This article adopts a microanalytic approach to examine storytelling as a co-construction by family members in a Cypriot-Australian family. Previous studies on family storytelling have focused on the various roles of family members in storytelling with a means of studying family socialization (Miller et al., 1990; Ochs & Taylor, 1992; Blum-Kulka, 1997). These studies used critical discourse analysis, socioculturel theories, performance and pragmatic approaches to storytelling. This article offers a distinctive approach to family storytelling by examining the discourse and social identities that family members display during the storytelling. The data originate in a study that involves interviews with three generations of Greek-Australian and Cypriot-Australian women regarding their relationships with each other. In this paper we investigate the contributions of the father and the daughters in the course of the mother's turn at storytelling. The first part of the analysis focuses on the husband's discourse identities as a contributor, initiator and elicitor of his wife's storytelling. During the storytelling we also observe the production and exchange of different social identities between the husband and the mother, such as the 'unwilling suitor', the 'embarrassed schoolgirl' or the 'forceful but teasing husband'. The second part describes how the daughters take part in their mother's storytelling, producing a variety of identities such as the 'impatient mother', the 'complaining', 'happy', or 'good' mothers and daughters. These investigations succinctly illustrate how narratives become a resource for members' 'display' and 'play' of identities. Copyright ©2002, John Benjamins B.V.

There has been a long history of contact between Indigenous and Chinese people in north-eastern Australia. This is evidenced in contemporary communities by the significant presence of mixed-heritage individuals of Indigenous and Chinese ancestry. This paper employs the stories of 10 such individuals to examine their incorporation of 'otherculture' ancestries into identity constructs. In doing so, the paper sheds light on how identities are narrated at the intersection of 'myth' and 'moment', and how challenge evokes transformation and discontinuity. Three broad identity responses emerge from the data: affirmation of singular constructs; questioning and contemplation; and pluralist embracing of both cultures. Historical and contemporary discourses feature prominently, covertly and overtly restricting potential identifications. Mutuality and hegemonic rivalry are found to underpin the narration of relations between the two marginalised and racialised groups.

A course which has a large student enrolment consequently puts a heavy load on instructors both in the presentation and the assessment areas. In the School of Economics at the University of Queensland, this is the case for the quantitative analysis subjects. Assessment for many years has been through mid-semester and end of semester exams, as well as Computer Managed Learning (CML) assignments. In 2000 it was decided to incorporate a system of flexible assessment where neither the CML nor the mid-semester exam was compulsory. The outcomes are assessed and the advantages and disadvantages discussed.

The design of open-access elliptical cross-section magnet systems has recently come under consideration. Obtaining values for the forces generated within these unusual magnets is important to progress the designs towards feasible instruments. This paper presents a novel and flexible method for the rapid computation of forces within elliptical magnets. The method is demonstrated by the analysis of a clinical magnetic resonance imaging magnet of elliptical cross-section and open design. The analysis reveals the non-symmetric nature of the generated Maxwell forces, which are an important consideration, particularly in the design of superconducting systems.

Workflow technology provides a suitable platform to define and manage the coordination of business process activities. We introduce a flexible e-learning environment – called Flex-eL – that has been built upon workflow technology. The workflow functionality of Flex-eL manages the coordination of learning and assessment activities of the course process between students and teaching staff. It provides a unique environment for teachers to design and develop process-centric courses and to monitor student progress. It allows students to learn at their own pace while observing the learning guidelines and checkpoints modeled into the course process by teaching staff. We also report on the successful deployment of the concept and system for university courses and our experiences from the implementation.

Electronic energy transfer (EET) rate constants between a naphthalene donor and anthracene acceptor in [ZnL4a](ClO4)(2) and [ZnL4b](ClO4)(2) were determined by time-resolved fluorescence where L-4a and L-4b are the trans and cis isomers of 6-((anthracen-9-yl-methyl)amino)-6,13-dimethyl-13-((naphthalen-1-yl-methyl)amino)-1,4,8,11-tetraazacyclotetradecane, respectively. These isomers differ in the relative disposition of the appended chromophores with respect to the macrocyclic plane. The trans isomer has an energy transfer rate constant (k(EET)) of 8.7 x 10(8) s(-1), whereas that of the cis isomer is significantly faster (2.3 x 10(9) s(-1)). Molecular modeling was used to determine the likely distribution of conformations in CH3CN solution for these complexes in an attempt to identify any distance or orientation dependency that may account for the differing rate constants observed. The calculated conformational distributions together with analysis by H-1 NMR for the [ZnL4a](2+) trans complex in the common trans-III N-based isomer gave a calculated Forster rate constant close to that observed experimentally. For the [ZnL4b](2+) cis complex, the experimentally determined rate constant may be attributed to a combination of trans-Ill and trans-I N-based isomeric forms of the complex in solution.

A method is proposed for determining the optimal placement and controller design for multiple distributed actuators to reduce the vibrations of flexible structures. In particular, application of piezoceramic patches to a horizontally-slewing single-link flexible manipulator modeled using the assumed modes method is investigated. The optimization method uses simulated annealing and allows placement of any number of distributed actuators of unequal length, although piezoceramics of fixed equal lengths are used in the example. It also designs an linear-quadratic-regulator controller as part of the optimization procedure. The measures of performance used in the investigation to determine optimality are the total mass of the system and the time integral of the absolute value of the hub and tip position error. This study also varies the relative weightings for each of these performance measures to observe the effects on the controller designs and piezoceramic patch positions in the optimized solutions.

The interaction between the growth of flexible forms of employment and employer funded training is important for understanding labour market performance. In particular, the idea of a trade-off has been advanced to describe potential market failures in the employment of flexible workers. This study finds that evidence of a trade-off is apparent in both the incidence and intensity of employer funded training. Flexible workers receive training that is 50-80% less intense than the workforce average. Casual workers - especially males - suffer more acutely from the trade-off. This suggests that flexible production externalities may seriously reduce human capital formation in the workforce.
