    Software architecture evaluation involves evaluating different architecture design alternatives against multiple quality-attributes. These attributes typically have intrinsic conflicts and must be considered simultaneously in order to reach a final design decision. AHP (Analytic Hierarchy Process), an important decision making technique, has been leveraged to resolve such conflicts. AHP can help provide an overall ranking of design alternatives. However it lacks the capability to explicitly identify the exact tradeoffs being made and the relative size of these tradeoffs. Moreover, the ranking produced can be sensitive such that the smallest change in intermediate priority weights can alter the final order of design alternatives. In this paper, we propose several in-depth analysis techniques applicable to AHP to identify critical tradeoffs and sensitive points in the decision process. We apply our method to an example of a real-world distributed architecture presented in the literature. The results are promising in that they make important decision consequences explicit in terms of key design tradeoffs and the architecture`s capability to handle future quality attribute changes. These expose critical decisions which are otherwise too subtle to be detected in standard AHP results.

    Network and stakeholder analyses in tourism studies typically offer schema, typologies, and frameworks that contribute to the conceptual development of the subject area. What has been lacking is the managerial application of network research in tourism. This paper offers a method for investigating and conceptualising network relationships in a regional tourism district. The field work was undertaken in the Australian wine region of the Hunter Valley. The findings from are analysed using four different approaches to the conceptualisation and classification of inter-organisational relationships in a tourism region: (1) the application of a value net to the region’s stakeholders, (2) the generation of a partnership-activities matrix, (3) an ecological approach using Budowski’s (1976) typology and (4) identifying the competition for scarce resources among tourism stakeholders. Managerial implications for each approach are described.

    Section 50 of the Australian Securities and Investments Commission Act 2001 (Cth) confers a wide power on the Australian Securities and Investment Commission (ASIC) to bring civil action in the name of the company or a class action for shareholders or investors for the recovery of damages for corporate misconduct. Despite its broad scope, this power has been little used by ASIC. Until the recent Westpoint litigation it appeared that this trend seemed set to continue due to the recent growth in ASIC’s arsenal of enforcement powers, in particular the ability to bring proceedings seeking civil penalties, together with what promises to be a new age of private enforcement of shareholders rights through class actions funded by litigation funding corporations. In the context of this likely expansion of private enforcement action and the current legislative framework of ASIC’s enforcement powers, this article will examine when ASIC should bring civil action under this provision.

    Journal Article
    The conventional view of corporate regulation is that corporations are to be managed for the benefit of their shareholders. The general law and statutory duties of directors and officers reflect this “shareholder primacy norm”, with duties formulated to prevent directors acting otherwise than in the interests of shareholders. However, the general law and statutory duties are not identical. The remedies and enforcement mechanisms differ considerably, which raises the question as to whether the public enforcement of statutory duties carries with it a public interest mandate that general law duties do not. This article considers what role the public interest should have in enforcing statutory duties and whether such a role represents a challenge to the dominant shareholder primacy norm of corporate law. This issue is highly topical as recent decisions have suggested that the statutory duties of directors and officers are limited in their scope to protecting the interests of shareholders, even to the detriment of the public interest. We contest that viewpoint and argue that, at least in relation to statutory duties, directors and officers have obligations that extend beyond the narrow conception of the protection of shareholder wealth.

    Journal Article
    To review the current literature and discussion on institutional repository (IR) and open access (OA) issues, to provide examples from the Information Systems (IS) literature, and to propose the use of IS literature and further research to inform understanding of institutional repository implementations for library managers. Methodology/Approach: Recent literature is reviewed to provide the background to, and current issues in, the development of institutional repositories to support open access to refereed research output. Practical implications: Existing research is identified, as are areas for potential research. Brief examples from IS literature are provided which may provide strategies for libraries and other organisations to speed up their implementation of IR to provide access to, and management of, their own institutions refereed research output. Value of paper: The paper brings together recent opinion and research on IR and OA to provide librarians and other information managers with a review of the field, and proposes research on IR and OA building on existing IS as well as information management and librarianship research.

    Journal Article
    This study assessed the intermix of local citation analysis and survey of journal use and reading patterns for evaluating an academic library's research collection. Journal articles and their cited references from faculties at the University of New South Wales were downloaded from the Web of Science (WoS) and journal impact factors from the Journal Citation Reports. The survey of the University of New South Wales (UNSW) academic staff asked both reader-related and reading-related questions. Both methods showed that academics in medicine published more and had more coauthors per paper than academics in the other faculties; however, when correlated with the number of students and academic staff, science published more and engineering published in higher impact journals. When "recalled" numbers of articles published were compared to "actual" numbers, all faculties over-estimated their productivity by nearly two-fold. The distribution of cited serial references was highly skewed with over half of the titles cited only once. The survey results corresponded with U.S. university surveys with one exception: Engineering academics reported the highest number of article readings and read mostly for research related activities. Citation analysis data showed that the UNSW library provided the majority of journals in which researchers published and cited, mostly in electronic formats. However, the availability of non-journal cited sources was low. The joint methods provided both confirmatory and contradictory results and proved useful in evaluating library research collections.

    This paper reports the findings of an exploratory study of position vacant announcements appropriate for library and information studies (LIS) graduates appearing in the Sydney Morning Herald over a four week period in each of the following years: 2004, 1994, 1984 and 1974. The period studied witnessed change-demanding developments in information technologies as well as changes in workplace conditions and client expectations. The study collected data on the demands of employers as expressed through job advertisements that included data on work status (full-time, part-time, contract, casual), qualifications and the experience required of the information professional at the selected timeslots. To investigate similarities and differences between periods a content analysis and co-word analysis of the job advertisements was undertaken. The ads indicated a movement from simple advertisements in 1974 inviting applications for reference or technical services librarians, to complex and specialised positions being advertised in 2004 where the most called for attributes were interpersonal skills and behavioural characteristics.

    Journal Article
    The purpose of this paper is to develop an understanding of the knowledge, skills and competencies demanded of early career information systems (IS) graduates in Australia. Online job advertisements from 2006 were collected and investigated using content analysis software to determine the frequencies and patterns of occurrence of specific requirements. This analysis reveals a dominant cluster of core IS knowledge and competency skills that revolves around IS Development as the most frequently required category of knowledge (78% of ads) and is strongly associated with: Business Analysis, Systems Analysis; Management; Operations, Maintenance & Support; Communication Skills; Personal Characteristics; Computer Languages; Data & Information Management; Internet, Intranet, Web Applications; and Software Packages. Identification of the core cluster of IS knowledge and skills – in demand across a wide variety of jobs – is important to better understand employers’ needs for and expectations from IS graduates and the implications for education programs. Much less prevalent is the second cluster that includes knowledge and skills at a more technical side of IS (Architecture and Infrastructure, Operating Systems, Networks, and Security). Issues raised include the nature of entry level positions and their role in the preparation of their incumbents for future more senior positions. The findings add an Australian perspective to the literature on information systems job ads and should be of value to educators, employers, as well as current and future IS professionals.

    Journal Article
    Purpose – To provide a social-theoretic framework which explains how e-commerce affects social conditions, such as availability of information and equality of access to information, influences actors’ behavior, shapes e-commerce business models, and in turn impacts industry structure. Design/methodology/approach – Empirical investigation based on one-hour interviews with owners/managers of nine vehicle dealerships and six vehicle buyers in a large US metropolitan region. The hermeneutic method of understanding was used, involving a circular process from research design and attentiveness to data, to data collection and interpretation. This circular process exemplified the dialectic relationship between the theoretical framework (derived from Habermas’s Theory of Communicative Action) and empirical data, through which interpretation and theoretical explanations grounded in the data emerged. Findings – Demonstrates that e-commerce gives rise to increasing competition among the dealers, decreasing prices and migration of competition to price, decreasing profitability of the average dealer, and erosion of traditional sources of competitive advantage. Moreover, e-commerce emancipates and empowers vehicle purchasers while reducing the power of automobile dealers. Research limitations/implications – The research findings focus on the effects of e-commerce on the automobile distribution industry. However, one could argue that a number of the findings extend to other retailing-based industries. Practical implications – The paper illustrates a research methodology that may be useful to study other e-commerce applications. Originality/value – This paper illustrates the application of Habermas’s Theory of Communicative Action to studying the effect of e-commerce.

    This paper examines the spillover impacts of the U.S. Fed’s and the European Central Bank (ECB)’s target interest rate news on the first two moments of the Asia-Pacific exchange rates against the US dollar and the euro over the period 1999-2006. The spillover effects on the mean are generally consistent with the literature where a majority of currencies depreciates against the USD and the EUR in response to unexpected rate rises. Both the Fed and the ECB news elicited tardy or persisting volatility responses. The Fed’s news tends to send a leading signal upon the upcoming decision of the ECB, while the ECB’s news tends to confirm the Fed’s decision. This relationship between the news tends to help reduce volatility in the Asia-Pacific currency markets.
