The adoption of web services based architectures in Australian organisations : an exploratory study

This exploratory research study contributes to answering two related research questions. First it identifies the key influences that seem to be driving and constraining the adoption of Service Oriented Architecture (SOA) and XML/Web Services and secondly it adduces some evidence to confirm that these influences significantly differ from those found by IS researchers in the adoption of other innovations in organisations. The key drivers were found to include improved agility, reuse and [open standards enabled] interoperability. None of these map easily to factors identified in previous Diffusion of Innovations (DOI) related IS research. In spite of standards being originally seen as strengths, it was found that the lack of IT industry agreement on the next generation of Web Services standards is now emerging as a perceived constraint. Variants of the ‘network effect’ such as partner push and client drag were also found to be influential.

Case Study from Australia Post : towards the online economy with netPOS

Examines how the "old economy" of the traditional postal service has changed over time and how Australia Post is adapting to the many pressures that threaten its existence. With increasing adoption of e-mail as a means of communication, increased competition as a result of deregulation, and the strain of servicing a country with huge distances between inhabited locations and low population density, Australia Post needed to find a solution that would ensure the long-term viability of its business. The retail sector, with its 4,000-plus post office outlets, processed many different types of across-the-counter financial transactions, including banking transactions and utility payments. A project team was established to address the fundamental issue of how to structure the IT infrastructure to enable retail outlets to generate future revenue flows for Post. However, having established the Internet-based infrastructure to connect the extensive chain of retail outlets, the question was whether this new infrastructure would successfully entice third parties to buy into the model.

Polyglutamine tracts as modulators of transcriptional activation from yeast to mammals

 Microsatellite repeats are genetically unstable and subject to expansion and shrinkage. A subset of them, triplet repeats, can occur within the coding region and specify homomeric tracts of amino acids. Polyglutamine (polyQ) tracts are enriched in eukaryotic regulatory proteins, notably transcription factors, and we had shown before that they can contribute to transcriptional activation in mammalian cells. Here we generalize this finding by also including evolutionarily divergent organisms, namely, Drosophila and baker's yeast. In all three systems, Gal4-based model transcription factors were more active if they harbored a polyQ tract, and the activity depended on the length of the tract. By contrast, a polyserine tract was inactive. PolyQs acted from either an internal or a C-terminal position, thus ruling out a merely structural 'linker' effect. Finally, a two-hybrid assay in mammalian cells showed that polyQ tracts can interact with each other, supporting the concept that a polyQ-containing transcription factor can recruit other factors with polyQ tracts or glutamine-rich activation domains. The widespread occurrence of polyQ repeats in regulatory proteins suggests a beneficial role; in addition to the contribution to transcriptional activity, their genetic instability might help a species to adapt to changing environmental conditions in a potentially reversible manner.

Transforming roles to support student development of academic literacies: a reflection on one team’s experience

Abstract: Social work is a discipline that attracts students from diverse academic backgrounds. Many are first in family to attend university, and come to university through alternative pathways such as vocational education. As a result, there are higher levels of attrition compared to other disciplines, especially in the first year. To address this, and in keeping with a commitment to provide accessible education, one school of social work undertook a project to embed academic literacies into the curriculum. This paper used Gibb’s reflective process to explore how this was experienced by team members. Data were collected via staff focus groups at two different points in time across the project and compared. The reflection unpacked a number of tensions experienced by team members, including concerns about potential loss of resources as a result of academics adopting new roles, and concerns about implementing what was seen as Westernised academic skills which may not fit with students’ ways of thinking and creating knowledge. Overfull curricula and constant change also appeared to be of concern. The reflection highlighted that to achieve effective and sustainable change, action was required at multiple levels.

Rethinking grassroots campaigners in the digital media: The ‘grassroots orchestra’ in Italy

The diffusion of digital media allows the emergence of new types of relations between grassroots campaigners and organisers. This article presents the results of a comparative qualitative study of two Italian cases of grassroots online participation: a local electoral campaign and a single-issue social movement. The first case is ‘Tell your Milano’, a project that took place during the electoral campaign for Mayor of Milan in the spring of 2011. The second case is the ‘Purple People’ (Popolo Viola), an Italian social movement started in 2009 to demand the resignation of the Prime Minister, Silvio Berlusconi. The article introduces the concept of a ‘grassroots orchestra’: a grassroots campaign aimed at a short-term objective, coordinated by a non-grassroots political actor and performed by a community sharing a uniform and coherent context.
