Cultural factors behind the adoption of e-learning in Turkey

This paper aims to examine ways in which cultural factors shape the adoption and use of information technology for online teaching. This research focuses on influential early adopters in the tertiary education sector in Turkey who have become change-agents by inspiring small networks of their peers. The study examines the operation of trust and inspiration in networking and teamwork in the Asian academic environment. Findings from this research can assist individuals and institutions to better understand ways in which to optimize the online teaching and learning experience for staff.

Trust in B2C e-commerce for the New Zealand Maori

This study was performed to allow an understanding of some of the elements of trust that are apparent to encourage the Mäori Internet shopper to feel comfortable to shop online. Mäori arrived in New Zealand from the Pacific over 1,000 years ago. Since then, New Zealand was colonised by Europeans in the 19th century. As a result, the Mäori have become a minority (Belich, 1996). That is, their culture, language and values have become secondary to those of the dominant European culture (Liu, Wilson, McClure & Higgins, 1999). Mäori have been defined as including “all those who identify themselves as belonging to the New Zealand Mäori ethnic group, either alone or in combination with any other ethnic group” (Statistics New Zealand, 1998, p. 94).

Power and politics in a system implementation

The central concern of this study is to identify the role of power and politics in systems implementation. The current literature on systems implementation is typically divided into two areas, process modelling and factor based studies. Process modelling classifies the implementation into a linear process, whereas factor based studies have argued that in order to ‘successfully’ implement a system, particular critical factors are required. This literature misses the complexities involved in systems implementation through the human factors and political nature of systems implementation and is simplistic in its nature and essentially de-contextualises the implementation process. Literature has investigated some aspects of human factors in systems implementation. However, it is believed that these studies have taken a simplistic view of power and politics. It is argued in this thesis that human factors in systems implementation are constantly changing and essentially operating in a dynamic relationship affecting the implementation process. The concept of power relations, as proposed by Foucault (1976, 1977, 1978, 1980, 1982), have been utilised in order to identify the dynamic nature of power and politics. Foucault (1978) argued that power is a dynamic set of relationships constantly changing from one point in time to the next. It is this recognition that is lacking from information systems. Furthermore, these power relations are created through the use of discourse. Discourse represents meaning and social relationships, forming both subjectivity and power relations. Discourses are also the practices of talk, text and argument that continuously form that which actors speak. A post-structuralist view of power as both an obvious and hidden concept has provided the researcher a lens through which the selection and implementation of an enterprise-wide learning management system can be observed. The framework aimed to identify the obvious process of system selection implementation, and then deconstruct that process to expose the hegemonic nature of policy, the reproduction of organisational culture, the emancipation within discourse, and the nature of resistance and power relations. A critical case study of the selection and implementation of an enterprise-wide learning management system at the University of Australia was presented providing an in-depth investigation of the implementation of an enterprise-wide learning management system, spanning five years. This critical case study was analysed using social dramas to distinguish between the front stage issues of power and the hidden discourses underpinning the front stage dramas. The enterprise-wide learning management system implemented in the University of Australia in 2003 is a system which enables academic staff to manage learners, the students, by keeping track of their progress and performance across all types of training activities. Through telling the story of the selection and implementation of an enterprise-wide learning management system at the University of Australia discourses emerged. The key findings from this study have indicated that the system selection and implementation works at two levels. The low level is the selection and implementation process, which operates for the period of the project. The high level is the arena of power and politics, which runs simultaneously to the selection and implementation process. Challenges for power are acted out in the front stage, or public forums between various actors. The social dramas, as they have been described here, are superfluous to the discourse underpinning the front stage. It is the discourse that remains the same throughout the system selection and implementation process, but it is through various social dramas that reflect those discourses. Furthermore, the enactment of policy legitimises power and establishes the discourse, limiting resistance. Additionally, this research has identified the role of the ‘State’ and its influence at the organisational level, which had been previously suggested in education literature (Ball, 1990).

Diverse fibrillar peptides directly bind the Alzheimer’s amyloid precursor protein and amyloid precursor-like protein 2 resulting in cellular accumulation

The Alzheimer’s disease Aβ peptide can increase the levels of cell-associated amyloid precursor protein (APP) in vitro. To determine the specificity of this response for Aβ and whether it is related to cytotoxicity, we tested a diverse range of fibrillar peptides including amyloid-β (Aβ), the fibrillar prion peptides PrP106–126 and PrP178–193 and human islet-cell amylin. All these peptides increased the levels of APP and amyloid precursor-like protein 2 (APLP2) in primary cultures of astrocytes and neurons. Specificity was shown by a lack of change to amyloid precursor-like protein 1, τ-1 and cellular prion protein (PrPc) levels. APP and APLP2 levels were elevated only in cultures exposed to fibrillar peptides as assessed by electron microscopy and not in cultures treated with non-fibrillogenic peptide variants or aggregated lipoprotein. We found that PrP106–126 and the non-toxic but fibril-forming PrP178–193 increased APP levels in cultures derived from both wild-type and PrPc-deficient mice indicating that fibrillar peptides up-regulate APP through a non-cytotoxic mechanism and irrespective of parental protein expression. Fibrillar PrP106–126 and Aβ peptides bound recombinant APP and APLP2 suggesting the accumulation of these proteins was mediated by direct binding to the fibrillated peptide. This was supported by decreased APP accumulation following extensive washing of the cultures to remove fibrillar aggregates. Pre-incubation of fibrillar peptide with recombinant APP18–146, the putative fibril binding site, also abrogated the accumulation of APP. These findings show that diverse fibrillogenic peptides can induce accumulation of APP and APLP2 and this mechanism could contribute to pathogenesis in neurodegenerative disorders.

Performing the technical image

The recent public multi-screen performance of formalist experimental animation by film artists such as Guy Sherwin, Bruce McLure and Greg Pope respond to the immediacy and speed of new digital technologies, the rise of Vilem Flusser’s ‘technical image’ and the consequent disappearance of reflective space identified by Prensky, Kroker, Virilio and Postman. Flusser’s ‘technical images’, benefiting from the digital’s painterly hyper-malleability structure and content, signifier and signified, so much the subject of Peter Gidal’s arguments in support of his concept of ‘materialist film’ in the 1970’s.  In the digital those formal editing strategies used to create the ‘technical image’ within analogue image construction that traditionally took place in the artist’s studio within the camers and optical printer are now executed inside the computer, having migrated into the post-production process.  Within the work of these artist’s recent multi-screen presentations these manipulations are now-elusively experienced in live ephemeral performance, re-forming and laying bare those processes that have been rendered invisible in digital technology.  The significance of this work partly lies in its ability to communicate historical information a-historically. Guy Sherwin and Lynn Loo’s method in their play with 16mm film flashes and after-images and Sherwin’s mirror performance further reproduces Goethe’s method from his Theory of Colours (1840). Greg Pope’s scratch performances re-enact the operation of Konrad Zuse’s 1930’s computing machine. Affinities are drawn between Bruce McLure’s immersive overpowering sonic and flicker performances with Edwin Land’s 1960’s experiments on colour constancy on which Land’s Retinex Theory of colour is based.
