Exploring the adoption of interactive digital television services as a retail shopping platform

The aim of this research is to consider the possible effect of an emerging technology platform on the uptake of online shopping: interactive (digital) Television (iTV), which enables viewers to select a variety of viewing options, publicity materials, games, entertainment and more recently shopping. An augmented version of the original TAM is applied to this study. Two new constructs are considered namely access and awareness together with perceived ease of use, perceived usefulness, perceived enjoyment and security. The results show that indeed the augmented TAM can be used as a predictive model for the adoption of iTV as an online shopping platform. It is concluded that access, perceived ease of use, perceived enjoyment and perceived usefulness are significant factors to determine the consumers’behavioural intentions towards the use of digital TV as a new shopping platform. However, awareness and security are considered to be insignificant with no effect on consumers’ behavioural intentions towards the new shopping medium.

French television talk: what tenses for past time?

On the basis of a transcribed French television corpus made of two news bulletins, two chat shows and one literary programme recorded in February 2003, this paper explores the claim that passé simple (PS) may still be used in prepared oral discourse (Pfister 1974). The corpus does not provide support for that use on television, but it seems to suggest a shift from temporal to aspectual features in French television talk: a perfective presentation prevails on a past presentation. This trend would need to be confirmed by a larger television corpus, tested in other types of oral discourse and tested on written corpora.

A principled approach to interactive hierarchical non-linear visualization of high-dimensional data

Hierarchical visualization systems are desirable because a single two-dimensional visualization plot may not be sufficient to capture all of the interesting aspects of complex high-dimensional data sets. We extend an existing locally linear hierarchical visualization system PhiVis [1] in several directions: bf(1) we allow for em non-linear projection manifolds (the basic building block is the Generative Topographic Mapping -- GTM), bf(2) we introduce a general formulation of hierarchical probabilistic models consisting of local probabilistic models organized in a hierarchical tree, bf(3) we describe folding patterns of low-dimensional projection manifold in high-dimensional data space by computing and visualizing the manifold's local directional curvatures. Quantities such as magnification factors [3] and directional curvatures are helpful for understanding the layout of the nonlinear projection manifold in the data space and for further refinement of the hierarchical visualization plot. Like PhiVis, our system is statistically principled and is built interactively in a top-down fashion using the EM algorithm. We demonstrate the visualization system principle of the approach on a complex 12-dimensional data set and mention possible applications in the pharmaceutical industry.

But somehow it was only television: West German Narratives of the fall of the Wall in recent novels and their screen adaptations

East Germans have long been criticised for harbouring a feeling of Ostalgie, a nostalgia for their old, Socialist state, but only recently has it become apparent that many west Germans obviously experience a similar sense of loss and longing for a seemingly simpler time before reunification. The texts that express these feelings tend to focus on the fall of the Wall as the pivotal point of change in German post-war history. Typically the characters in these books deny the significance and impact of this major political event and strive to reduce its importance, at best to a minor television moment. This attitude can be observed in the novels liegen lernen and Herr Lehmann and in their film adaptations. Despite having been accused of indulging a feeling of Westalgie, a closer analysis reveals that they are in fact deliberately provocative and challenge eastern and western stereotypes. In addition the films find ways to transport the books’ ironic narrative to the screen, and they also reinforce the authors’ implicitly critical attitude towards their characters’ political apathy by portraying the fall of the Wall in ways different to the books. The films react to the provocation voiced in the novels and function like an intertextual commentary as they integrate the opening of the border into a meaningful context for the protagonists and restore it to its historic importance.

Improving the use of visual interactive simulation as a knowledge elicitation tool

Knowledge elicitation is a well-known bottleneck in the production of knowledge-based systems (KBS). Past research has shown that visual interactive simulation (VIS) could effectively be used to elicit episodic knowledge that is appropriate for machine learning purposes, with a view to building a KBS. Nonetheless, the VIS-based elicitation process still has much room for improvement. Based in the Ford Dagenham Engine Assembly Plant, a research project is being undertaken to investigate the individual/joint effects of visual display level and mode of problem case generation on the elicitation process. This paper looks at the methodology employed and some issues that have been encountered to date. Copyright © 2007 Inderscience Enterprises Ltd.

A visual interactive modelling system as a learning tool

This paper presents a case study of the use of a visual interactive modelling system to investigate issues involved in the management of a hospital ward. Visual Interactive Modelling systems are seen to offer the learner the opportunity to explore operational management issues from a varied perspective and to provide an interactive system in which the learner receives feedback on the consequences of their actions. However to maximise the potential learning experience for a student requires the recognition that they require task structure which helps them to understand the concepts involved. These factors can be incorporated into the visual interactive model by providing an interface customised to guide the student through the experimentation. Recent developments of VIM systems in terms of their connectivity with the programming language Visual Basic facilitates this customisation.

Strategy as practice:Interactive governance spaces and the corporate strategies of retail transnationals

There is growing interest in the role of corporate governance systems within the strategy-making process of firms. Using a 'strategy as practice' perspective, we conceptualize the governance system as a contested space in which management and security analysts mutually adapt/transform and enact corporate strategies vis-à-vis argumentation. Synthesizing this micropractice perspective within corporate governance research, the supple role of securities analysts' arguments in shaping corporate strategies assumes a new significance. It also provides a basis for observing and understanding the contested nature of the retail internationalization process. The implications and opportunities for management studies and economic geography are considered. © The Author (2007). Published by Oxford Press. All rights reserved.

'Taking a sickie':Job satisfaction and job involvement as interactive predictors of absenteeism in a public organization

Correlations between absenteeism and work attitudes such as job satisfaction have often been found to be disappointingly weak. As prior work reveals, this might be due to ignoring interactive effects of attitudes with different attitude targets (e.g. job involvement and organizational commitment). Drawing on basic principles in personality research and insights about the situational variability of job satisfaction judgments, we proposed that similar interactions should be present also for attitudes with the same target. More specifically, it was predicted that job involvement affects absenteeism more if job satisfaction is low as this indicates a situation with weak constraints. Both attitudes were assessed in a sample of 436 employees working in a large civil service organization, and two indexes of absence data (frequency and time lost) were drawn from personnel records covering a 12-month period following the survey. Whereas simple correlations were not significant, a moderated regression documented that the hypothesized interaction was significant for both indicators of absence behaviour. As a range of controls (e.g. age, gender, job level) were accounted for, these findings lend strong support to the importance of this new, specific form of attitude interaction. Thus, we encourage researchers not only to consider interactions of attitudes with a different focus (e.g. job vs. organization) but also interactions between job involvement and job satisfaction as this will yield new insights into the complex function of attitudes in influencing absenteeism. © 2007 The British Psychological Society.

MILVA:An interactive tool for the exploration of multidimensional microarray data

Clustering techniques such as k-means and hierarchical clustering are commonly used to analyze DNA microarray derived gene expression data. However, the interactions between processes underlying the cell activity suggest that the complexity of the microarray data structure may not be fully represented with discrete clustering methods.

Foreign direct investment and economic development:an interactive relationship

With the increasing importance of Foreign Direct Investment (FDI), there have been substantial studies on this issue, both empirically and theoretically. However, most existing studies focus on either the impacts of FDI presence or the determinants of FDI inflows, ignoring the fact that inward FDI and economic development may simultaneously affect each other. This thesis sets out to examine the interactive effects between FDI and economic development. The whole thesis is composed of five chapters. Chapter One is an overall introduction to the thesis. Chapter Two presents a theoretical study and chapter Two and Three provide two empirical studies. Chapter Five concludes. Chapter Two presents a theoretical two-sector model that features the importance of human capital in attracting foreign investment. This model theoretically explains why FDI is more likely to occur among countries that are similar in terms of human capital and technology. On the other hand, MNCs must train local employees to work with firm-specific technology and hence improve the technological skills of local workers. In Chapter Two, an empirical model is constructed to detect whether the productivities of foreign and local firms impact each other. The model is tested on China’s data at the industry level. The results indicate that productivity growth of local and foreign firms are jointly determined. Evidence also suggests that the extent to which spillovers occur varies with difference technology levels of local firms. Chapter Four investigates the relationship between FDI and economic grown based on a panel of data for 84 countries over the period 1970-1999. Both equations of FDI inflow and GDP growth are examined. The results indicate that FDI not only directly promotes economic growth by itself, but also indirectly does so via its interaction terms. There is a strong positive interaction effect of FDI with human capital and a strong negative interaction effect of FDI with technology gap on economic growth in developing countries.

Teacher logs and interactive decision-making:a case study of contingencies in an EFL organizational culture and the implications for teacher development for part-time teachers

This is a case study of a program of native speaker part-time EFL (English as a Foreign Language) teachers in a junior college in Japan. It has grown out of a curiosity to ascertain how the teachers have formed and continue to maintain a coordinated program in what would seem to be a disadvantageous national context where as part-time foreign teachers they are expected to do little more than just teach a few classes of mainly oral English. This study investigates the organizational culture the teachers have formed for themselves within their staffroom, and looks at the implications of this for part-time teachers in such an environment. More specifically, the study highlights that central to the program is an interactive decision-making function engaged in by all the teachers which has not only created but also continually enables an identifiable staffroom culture. This organizational culture is contingent on college and staffroom conditions, program affordances such as shared class logs and curriculum sharing, and on the interactive decision-making itself. It is postulated that the contingencies formed in this created and continually creating shared world not only offer the teachers a proficient way to work in their severely time-constricted environment, but also provide them with fertile ground for the self-regulation of a thus created zone of covert staffroom ‘on-the-job’ teacher development.
