An investigation into challenges facing distributed teams: Case of South Australian construction projects

There is increasing momentum within the construction industry to deploy distributed teams on projects, yet the major challenges that companies face for managing teams in distributed arrangements have yet to be explored in the construction context. Driven by such need, this study is intended to present an account of the major challenges encountered throughout the life cycle of offshore outsourcing arrangements within the South Australian construction industry. To this end, the study describes the observations made within the natural contexts of one construction project in terms of the challenges to the success of deploying distributed teams for outsourcing of works. Discussions remain in dialogue with relevant theories and the pertinent literature to explain the interpretations and lessons learned and to underpin the conclusions made. It is contended that this study contributes to the field by providing an illuminating insight into potential challenges facing distributed teams being implemented in outsourcing tasks in construction projects. Discussions also offer practical guidelines for construction project managers and assist them in dealing with potential challenges of offshore outsourcing through the lenses of distributed team working principles.

Literacy teaching and learning in a digital world: Challenges of a new era

Teachers the world over are aware of the range of new challenges that arise from this new era. One challenge is the role of digital technologies in literacy learning. Despite its reputation for being engaging, digital technologies do not always enhance learning outcomes. Whilst the concerns vary across time and place, the core issue of what is a highly sought after literacy learning outcome in this new era warrants consideration. This paper introduces Kalantzis and Cope’s (2005) theorisation of eight knowledge processes for literacy learning. They claim that experiencing the known, conceptualising by naming, analysing functionally and applying appropriately, whilst necessary, are not on their own sufficient for the development of high level literacy practices. It is their contention that students must also be able to experience the new, conceptualise by theorising, analyse creatively and apply critically. This theorisation forms an auditing framework for considering the outcomes of different uptakes of digital technologies in a Social Studies and a Science unit.

Writing fashion’s future: the gods and monsters of the Anthropocene

This paper identifies two narratives of the Anthropocene and explores how they play out in the realm of future-looking fashion production. Each narrative draws on mythic comparisons to gods and monsters to express humanity’s dilemmas, albeit from different perspectives. The first is a Malthusian narrative of collapse and scarcity, brought about by the monstrous, unstoppable nature of human technology set loose on the natural world. In this vein, philosopher Slavoj Zizek (2010) draws on Biblical analogies, likening ecological crisis to one of the four horsemen of the apocalypse. To find a myth to suit the present times, novelist A.S Byatt (2011) proposes Ragnarök, a Norse myth in which the gods destroy themselves. In contrast, the second narrative is one of technological cornucopia. Stewart Brand (2009, 27), self-described ‘eco-pragmatist’ writes, ‘we are as gods and we have to get good at it’. In his view, human technologies offer the only hope to mitigating the problems caused by human technology – Brand suggests harnessing nuclear power, bioengineering of crops and the geoengineering of the planet as the way forward. Similarly, the French philosopher Bruno Latour (2012, 274), exhorts us to “love our monsters”, likening our technologies to Doctor Frankenstein’s monster – set loose upon the world, and then reviled by his creator. For both Brand and Latour, human technology may be monstrous, but it must also be turned toward solutions. Within this schema, hopeful visions of the future of fashion are similarly divided. In the techno-enabled cornucopian future, the fashion industry embraces wearable technology, speed and efficiency. Technologies such as waterless dyeing, 3D printing and self-cleaning garments shift fashion into a new era of cleaner production. Meanwhile, in the narrative of scarcity, a more cautious approach sees fashion return to a new localism and valuing of the hand-made in a time of shrinking resources. Through discussion of future-looking fashion designers, brands, and activists, this paper explores how they may align along a spectrum to one of these two grand narratives of the future. The paper will discuss how these narratives may unconsciously shape the perspective of both producers and users around the fashion of today and the fashion of tomorrow. This paper poses the question: what stories can be written for fashion’s future in the Anthropocene, and are they fated, or can they be re-written?

The sublime, affective process + architectural production

A year before Kate Nesbitt’s Theorising a New Agenda For Architecture (1996), the author penned a chapter on the significance of the sublime and its contribution to post-modern architecture via the uncanny or disturbing through the theories of Vidler and Eisenman (Nesbit, 1995). Twenty years on, we see its ongoing presence within the contemporary works of artists Kapoor, Ellison and Viola. Eisenmann and Libeskind aside, explicit reference to the Sublime whether through architectural praxis or theory appears to have been trumped by ecological derivatives and associated transactions, as catalyst for new architecture and architectural thinking. For Edmund Burke (1757), the Sublime was seen as a leading, an overpowering of self to a state of intense self-presence, often leading to a state of otherness. To experience the sublime is to experience affect, physiologically overwhelming the mental faculties through intensities of astonishment, terror, obscurity, magnificence, and reverence. Key here is Burke’s articulation of the stages of the sublime encounter, particularly so, its implications for the process of production which architectural theorists appear to have overstepped in their valorisation of the sublime object. This paper seeks to resituate the sublime within the context of architectural production. Through concepts such as material thinking, bodies and making strange, the paper explores a shift in focus toward affective processes traced from Burke’s inquiry. Rather than proposing strategies solely for affect within the work itself, the focus lies upon the designing experience, where blockage and desirous forces are critical partners in the process of production, as revealed through recent studio programs entitled Strange Space.

Bringing up Children Gran’s Way: Insights from a research project on Indigenous child and youth mental health

Background In 2000, the Mater Child and Youth Mental Health Service Indigenous consultant saw that Indigenous families were isolated from kinship networks following the assimilation policy and clinicians were largely unaware of these socio-cultural histories. Experiences of marginalisation by mainstream society and services were exacerbated by assumptions clinicians made about this population. To enhance Mater’s care the consultant undertook research with Indigenous Elders. The project, “Bringing up Children Gran’s Way”, on which the presenter is the research advisor, was funded by AIATSIS. Aims Increase service quality Improve staff confidence, skills and satisfaction working with this population Promote the wellbeing of Indigenous families Acknowledge the significance of Elders and extended family networks. Methods Over 2006/07 the team used narrative and Indigenous methodologies, (e.g. yarning circles and the use of Indigenous research staff) to arrange and audio-record structured interviews with 19 Aboriginal Elders, on growing up and parenting. The participants were recruited by the Indigenous consultant and gave written consent, following ethical approval and information giving. The team immersed themselves in the material by repeated reading of the transcripts to note recurring themes in Elders’ narratives. Findings The recurring themes included the importance of cultural protocols and extended family; impacts of being ‘under the Act and stories of surviving change; culture, spiritualty and religion; trans-generational impacts; childrearing and the need to reconcile with Elders. Discussion The narratives show Elders resilience in the face of enduring impact of policies of genocide and assimilation. Clinicians need to approach their work with a deeper understanding of the diversity of clients’ social experience and cultural identity. Clinicians need to examine their own cultural assumptions about this population. Conclusion The dissemination of the knowledge and experience of Elders is a matter of social justice and crucial for the well-being of future generations and for improved service access.

Response of the anterior sclera to accommodation in myopes and emmetropes

• The biomechanical properties of the sclera are documented to be altered in eyes with myopia, with the myopic sclera thought to be more susceptible to deformation from otherwise normal ocular forces. • The close anatomical and functional relationship between the ciliary body and sclera suggests that ciliary muscle contraction during accommodation may influence the overlying sclera. • This study aimed to characterise the changes occurring in anterior scleral thickness with accommodation using anterior segment optical coherence tomography (AS-OCT) in young adult myopes and emmetropes.

Ambient light exposure influences childhood eye growth

• Although there is evidence that outdoor activity is an important factor involved in the development of childhood refractive error,1,2 the mechanism underlying the association between more outdoor activity and less myopia in childhood is not clear. • In this prospective longitudinal study, the relationship between objectively measured ambient light exposure and eye growth in childhood was examined.

An efficient and light-weight multi-tasking model to achieve Intra-Agent concurrency for SAGE

Multi-agent systems implicate a high degree of concurrency at both the Inter- and Intra-Agent levels. Scalable, fault tolerant, Agent Grooming Environment (SAGE), the second generation, FIPA compliant MAS requires a built in mechanism to achieve both the Inter- and Intra-Agent concurrency. This paper dilates upon an attempt to provide a reliable, efficient and light-weight solution to provide intra-agent concurrency with-in the internal agent architecture of SAGE. It addresses the issues related to using the JAVA threading model to provide this level of concurrency to the agent and provides an alternative approach that is based on an eventdriven, concurrent and user-scalable multi-tasking model for the agent's internal model. The findings of this paper show that our proposed approach is suitable for providing an efficient and lightweight concurrent task model for SA GE and considerably outweighs the performance of multithreaded tasking model based on JAVA in terms of throughput and efficiency. This has been illustrated using the practical implementation and evaluation of both models. © 2004 IEEE.

Elliptical summary randomisation for sensor-based human activity recognition

Many conventional statistical machine learning al- gorithms generalise poorly if distribution bias ex- ists in the datasets. For example, distribution bias arises in the context of domain generalisation, where knowledge acquired from multiple source domains need to be used in a previously unseen target domains. We propose Elliptical Summary Randomisation (ESRand), an efficient domain generalisation approach that comprises of a randomised kernel and elliptical data summarisation. ESRand learns a domain interdependent projection to a la- tent subspace that minimises the existing biases to the data while maintaining the functional relationship between domains. In the latent subspace, ellipsoidal summaries replace the samples to enhance the generalisation by further removing bias and noise in the data. Moreover, the summarisation enables large-scale data processing by significantly reducing the size of the data. Through comprehensive analysis, we show that our subspace-based approach outperforms state-of-the-art results on several activity recognition benchmark datasets, while keeping the computational complexity significantly low.

Scalable fault tolerant agent grooming environment-SAGE

Multi-agent systems (MAS) advocate an agent-based approach to software engineering based on decomposing problems in terms of decentralized, autonomous agents that can engage in flexible, high-level interactions. This chapter introduces scalable fault tolerant agent grooming environment (SAGE), a second-generation Foundation for Intelligent Physical Agents (FIPA)-compliant multi-agent system developed at NIIT-Comtec, which provides an environment for creating distributed, intelligent, and autonomous entities that are encapsulated as agents. The chapter focuses on the highlight of SAGE, which is its decentralized fault-tolerant architecture that can be used to develop applications in a number of areas such as e-health, e-government, and e-science. In addition, SAGE architecture provides tools for runtime agent management, directory facilitation, monitoring, and editing messages exchange between agents. SAGE also provides a built-in mechanism to program agent behavior and their capabilities with the help of its autonomous agent architecture, which is the other major highlight of this chapter. The authors believe that the market for agent-based applications is growing rapidly, and SAGE can play a crucial role for future intelligent applications development. © 2007, IGI Global.
