Model-based development becomes more and more popular in the development of embedded software systems in the car industry. On the websites of tool vendors many success stories can be found, which report of efficiency gains from up to 50% in the development, high error reductions and a more rapid increase of the maturity level of developed functions (The Mathworks, 2010) (dSPACE 2010) just because of model-based development. Reliable and broadly spread research that analyze the status quo of model-based development and its effects on the economics are still missing. This chapter describes the results of a global study by Altran Technologies, the chair of software and systems engineering and the chair of Information Management of the University of Technology in Munich which examines the costs and benefits of model-based development of embedded systems in the car industry.

The second issue of PORTAL Journal of Multidisciplinary International Studies for 2006 features a special selection of essays grouped under the title ‘Women in Asia’ and guest-edited by Devleena Ghosh and Barbara Leigh, both from the University of Technology Sydney. The essays in this special issue had their first incarnations at the Eighth Women in Asia Conference, ‘Shadow Lines’, organised by the Women’s Caucus of the Asian Studies Association of Australia and the University of Technology Sydney (convened by Ghosh and Leigh), and held at the University of Technology Sydney from 26 to the 28 September 2005. Aiming self-consciously and tacitly to toy with, and dispute, the historical and discursive valencies accruing to the key, twined terms ‘women’ and ‘Asia’, the ten essays grouped here combine to form a rich repository of contemporary research about the status of women in many parts of that vast, arguably incoherent, geocultural space called Asia. All of the contributing authors thus ‘attempt to unsettle discourses about limits,’ to cite from co-editor Devleena Ghosh’s opening paper. That attempt is far from straightforward, as Ghosh elaborates: ‘That lines, borders and boundaries exist, whether of prejudice, politics, economics, or culture, is undeniable. But how do we analyse these issues without ossifying them, creating implacable alterities that refuse the liminal spaces that people occupy?’ Multivalent solutions are called for, Ghosh suggests, and these are to be found not simply in ‘counter-politics and interventions’, but also through the excavation and recognition of multiple subjectivities from/in ‘a thousand plateaus, [and] felt and experienced through the body, historical landscapes, domestic spaces, through performance as well as through the realm of the imaginary, in the impact of ideals and the weight of history’. In addition to the special section on ‘Women in Asia’, this edition of PORTAL contains two essays in its general academic section. François Provenzano’s ‘Francophonie et études francophones: considérations historiques et métacritiques sur quelques concepts majeurs’ offers a sustained meditation and critique of the discourse of Francophonic unity, and suggests a range of possible critical directions for future research into the study of French-speaking zones, peoples and cultures. Barbara Elizabeth Hanna and Juliana de Nooy’s ‘The Seduction of Sarah: Travel Memoirs and Intercultural Learning’, focuses on a big-selling memoir that was also something of a media-sensation on its publication in Australia in 2002, expatriate Australian journalist Sarah Turnbull’s account of her ambivalent ‘new life’ in Paris, France, after her marriage to a local: Almost French: A New Life in Paris. Interested in Turnbull’s autobiography as a potentially useful and productive classroom text for demonstrating, and enabling discussion of, intercultural difference, the authors’ rich analysis demonstrates that such texts present a host of problems to the teacher keen to work with students’ self-critical capacities to locate themselves in international and transcultural frameworks. We are delighted, as well, to present three cultural works in this issue: Katherine Elizabeth Clay’s evocative ‘comic’ narrative of study abroad, ‘From Penrith to Paris,’ itself a lively visual-textual antidote to Turnbull’s ambivalently romanticized view of (not-quite)-belonging in Paris (as discussed by Hanna and de Nooy in this issue); a typically idiosyncratic satire about the current German Chancellor, Angela Merkel, from Anthony Stephens, expertly deploying an ancient Celtic narrative verse form; and California-based Chicana writer Susana Chávez-Silverman’s code-switching chronicle/crónica, ‘Oda a la ambigüedad Crónica,’ a beautifully concise exploration of loss and the sensory regime of memorialisation.

Corona pandemic has a strong influence on almost all fields all over the world, especially in education. In Vietnam, in the case study of the University of Technology and Education Ho Chi Minh City (HCMUTE), most of the lecturers being responsible for theoretical subjects are required to teach their students online during the outbreak of COVID 19. It is a crucial issue that needs efficiency from online learning. This study aims to evaluate the status and efficiency of online learning at HCMUTE. Altogether 108 students and 25 lecturers participated in the study. The qualitative data collection tool was a questionnaire that has open and closed questions related to the learning environment, the interaction relationships, and learning outcomes. The results show that there is a synchronous learning environment and plenty of digital tools used by most lecturers. About 74 percent of students are satisfied and keen on continuing online learning; a large number of lecturers would like to continue with blended learning. Besides, the study also found out some difficulties that focus on two main issues such as technical issues, and decreasing students’ activeness during online classes. The study also recommends three learning activities design stages that the lecturers can apply for their online teaching to encourage students to active learning. This research extends knowledge of pedagogy and orient the next online course design at UTEx.

Like all professional education and training, health information management education has changed and developed in response to technological demands, employer requirements and the evolving nature of the discipline. In this series of reports, four Australian universities — Curtin University of Technology, La Trobe University, The University of Sydney and Queensland University of Technology — OTEN (Open Training Education Network) and HIMAA Education Services describe courses, students and aims of their programs.

This article reports the results of an industrial case study demonstrating the efficacy of a model-based testing process in assuring the quality of highly configurable systems from the automation domain. Escalating demand for flexibility has made modern embedded software systems highly configurable. This configurability is often realized through parameters and a highly configurable system possesses a handful of those. Small changes in parameter values can account for significant changes in the system’s behavior, whereas in other cases, changed parameters may not result in any perceivable reaction. This case study addresses the challenge of applying model-based testing to configurable embedded software systems to reduce development effort. As a result of the case study, a model-based testing process was developed and tailored toward the needs of the automation domain. This process integrates existing model-based testing methods and tools, such as combinatorial design and constraint processing. The testing process was applied as part of the case study and analyzed in terms of its actual saving potentials, which reduced the testing effort by more than a third.
