Testing some myths about I.T. outsourcing : a survey of Australia's top 1000 firms

This study examines the extent to which surveyed outcomes of IT outsourcing supported several commonly-argued propositions. Following confirmatOl), factor analysis, eight measures of success were used: access to skilled staff, technology benefits, economies of scale, cost reductions, strategic benefits, technical service quality, capacity to concentrate on core business, and overall satisfaction/value. The analysis produced some surprising findings. Some widely-promoted benefits of outsourcing were reported by most respondents, but other benefits that have been similarly promoted (such as cost savings) were reported by only a minority of respondents. There were no differences in success outcomes between medium-sized «500 employees), large (500 to 1000 employees), and very large (1000+ employees) organizations. There were some minor differences between government agencies and finns from the private sector, but no differences for key outcomes. Contrary to findings from case study research, "selective" outsourcing was no more successful than "total" outsourcing, although "total" outsourcing was uncommon. On the basis of these results, decision makers are urged to be cautious when planning to outsource IT services, and to be critical of claims that they will make substantial savings from outsourcing, or that outsourcing will automatically allow them to refocus more on their core business.

Corporate sustainability : greenwash or a path to sustainable capitalism?

The problems of unsustainable development and the increased-awareness of corporate power in the global era have contributed to an agenda of corporate citizenship. This thesis explores the meanings and practices that fall under the banner of the triple bottom line of corporate citizenship through forty-two in-depth interviews with representatives from the corporate sector and NGO sector (including trade unions) in Australia. This purposive sample includes a specific range of corporate industries and NGO types, all of which have involvement with various areas of sustainability. Interviewees described their feelings and experiences in relation to the concept of the triple bottom line, the potential and limitations of this type of sustainability and the purpose and impacts of partnerships between NGOs and the corporate sector. On the basis of this research, this thesis argues that corporate citizenship is at best, a set of initiatives for making minor adjustments to the way companies perform their day-to-day operations and at worst, a program for improving corporate image rather than performance and for shifting the agenda of sustainable development toward corporate interests. While radical steps are required to achieve a sustainable society and environment, the terms of corporate citizenship offer very limited opportunities for change. The self-regulatory and market based model of citizenship does not challenge the impact of consumerism or the legitimacy of particular industry types and their products, except where threats are perceived to the longevity of the companies involved. Furthermore, while the exploitation of the environment and society has occurred as a result of corporate self-interest, corporate citizenship is justified on the same basis. The self-interest rationale and the tyranny of the economic bottom line in particular, substantially limit the fields of responsibility that can be included in the citizenship paradigm. While there are undoubtedly some well-intentioned corporate representatives who are working toward attaining a more sustainable corporate culture, the discourse is primarily used to shift the sustainable development agenda toward corporate paradigms and interests.

Upgrading arc median shortest path problem for an urban transportation network

In this paper, we propose an algorithm for an upgrading arc median shortest path problem for a transportation network. The problem is to identify a set of nondominated paths that minimizes both upgrading cost and overall travel time of the entire network. These two objectives are realistic for transportation network problems, but of a conflicting and noncompensatory nature. In addition, unlike upgrading cost which is the sum of the arc costs on the path, overall travel time of the entire network cannot be expressed as a sum of arc travel times on the path. The proposed solution approach to the problem is based on heuristic labeling and exhaustive search techniques, in criteria space and solution space, respectively. The first approach labels each node in terms of upgrading cost, and deletes cyclic and infeasible paths in criteria space. The latter calculates the overall travel time of the entire network for each feasible path, deletes dominated paths on the basis of the objective vector and identifies a set of Pareto optimal paths in the solution space. The computational study, using two small-scale transportation networks, has demonstrated that the algorithm proposed herein is able to efficiently identify a set of nondominated median shortest paths, based on two conflicting and noncompensatory objectives.

Standard setting in specific-purpose language testing: what can a qualitative study add?

This paper explores the views of nursing and medical domain experts in considering the standards for a specific-purpose English language screening test, the Occupational English Test (OET), for professional registration for immigrant health professionals. Since individuals who score performances in the test setting are often language experts rather than domain experts, there are possible tensions between what is being measured by a language test and what is deemed important by domain experts. Another concern is a lack of qualitative research on the process of the standard setting. To date, no published qualitative work has been identified about the contributions of domain experts in the standard setting for healthcare communication. In this study, a standard-setting exercise was conducted for the speaking component of the OET, using judgements of nursing and medical clinical educators and supervisors. In all, 13 medical and 18 nursing clinical educators and supervisors rated medical and nursing candidate performances respectively. These performances were audio-recorded OET role-plays that were selected across a range of proficiency levels. Domain experts were invited to comment on the basis of their decisions and the extent of alignment between these decisions and the criteria used to assess performance on the OET. Nursing and medical domain experts showed that they attended to all of the OET criteria in making their decisions about standards. However, clinical scenario simulation also invited judgements of clinical competence from participants, even where they knew that clinical competence should be excluded from their decision-making. Another concern related to the authenticity limitations of the role-play tasks as evidence of readiness to handle communication in the workplace. Overall, findings support the value of qualitative evidence from the standard setting in providing insight into the factors informing and impeding decision-making.

Defining marine important bird areas: testing the foraging radius approach

Recent international initiatives have promoted a number of different approaches to identify marine Important Bird and biodiversity Areas (IBAs), which are important areas for foraging, migrating or over-wintering seabirds. The 'Foraging Radius Approach' is one of these and uses known foraging range and habitat preferences to predict the size and location of foraging areas around breeding colonies. Here we assess the performance of the Foraging Radius Approach using GPS tracking data from six seabird species with a variety of foraging modes. For each species we compared the population home-range areas of our six study species with the home-range areas defined using the Foraging Radius Approach. We also assessed whether basic information on depth preferences from tracking data could improve these home-range area estimates. Foraging Radius Approach home-range areas based on maximum foraging radii encompassed the entire population home-range of five out of six of our study species but overestimated the size of the population home-range area in every case. The mean maximum foraging radius overestimated the population home-range areas by a factor of 4-14 for five of the six species whilst the mean foraging radius overestimated the population home-range area for half of the species and underestimated for the rest. In the absence of other data, the Foraging Radius Approach appears to provide a reasonable basis for preliminary marine IBA identification. We suggest that using the mean value of all previously reported maximum foraging radii, informed by basic depth preferences provides the most appropriate prediction, balancing the needs of seabirds with efficient use of marine space.
