Perpetuating sales: enabling incumbent survival of radical technological shifts

This paper examines an industry whose incumbents’ specialised complimentary assets were their operations management and distribution channels. This advantage was seriously undermined by the advent of digital distribution. Radical technological change theories dictate that if incumbents in an industry without specialised complimentary assets will be replaced by entrants. This did not happen, and extant theories of incumbent survival do not explain why the incumbents remained dominant in the industry. We propose that survival is due to the unique industry characteristic of perpetuating sales. This paper will explain what is a perpetuating sales model and why does it enable incumbent survival?

Towards a digital poetics

This thesis extrapolates electronic literature’s différance, proposing an ontology of the form through critical inspection of its traits and peculiarities. Rather than offering a prescriptive definition of electronic literature, this thesis takes an ontological approach through descriptive exploration. In essence, my approach is anti-essentialist, in that I dismiss the view that electronic literature has a specific set of attributes. As will be explored throughout, there are aesthetic properties which frequently emerge, but the implication of their presence remains transient, to the point where electronic literature cannot be one thing, for to be so, it could not be literary. Computational aesthetics resist stable definition, so if we are to achieve an understanding of what separates electronic literature – if it is indeed, separate – from its non-digital counterparts, then we must do so through an articulation of those differences which may, at first, be less apparent. It is an impossibility to state what electronic literature is, as in doing so, one is oblivious to what it might become. The heightened relationship between form and content encountered in this field means that electronic literature is continuously in flux. Literature, while equally resistant to definition, is at least recognisable to our faculties. As readers, we have long possessed the sensibilities necessary to discern the literary from the communicative. Non-digital literary content is open to evolution and experimentation, but predominantly, with a few exceptions, its paratextual form remains consistent. Electronic literature’s content is open to the same artistic manipulation as the physical, but its form too, symbiotically attached to the exponential rate of technological change, gives rise to phenomenological disruption. As multimodal aesthetics challenge our ability to perceive the literary, we should abandon our attempts at defining the relevant works, and instead, seek understanding through analyses of the means by which they differ, and of how they defer, from the literatures that have both preceded and characterised the digital age. This thesis does not seek to resolve the aporetic, but rather, demonstrates how we must extract our theories of the digital out of observation and analysis, as opposed to speculation. This is not to say that my peers are necessarily wrong; I will be in agreement with many of them on a number of matters. My purpose, rather, is to offer some synthesis to a field comprised of a multiplicity of divergent views. Throughout the process of presenting this notion of a new modernity, and offering synthesis to the theories that have emerged from this epoch, I will offer fresh insights and novel approaches to the literary practices of the digital age. In doing so, my purpose will be to contribute to the progression of a consistent and legitimate digital poetics by showing that it cannot be one thing, but a balance of forces – a poetics of equipoise.

Cereal products for specific dietary requirements. Evaluation and improvement of technological and nutritional properties of gluten free raw materials and end products

Coeliac disease is one of the most common food intolerances worldwide and at present the gluten free diet remains the only suitable treatment. A market overview conducted as part of this thesis on nutritional and sensory quality of commercially available gluten free breads and pasta showed that improvements are necessary. Many products show strong off-flavors, poor mouthfeel and reduced shelf-life. Since the life-long avoidance of the cereal protein gluten means a major change to the diet, it is important to also consider the nutritional value of products intending to replace staple foods such as bread or pasta. This thesis addresses this issue by characterising available gluten free cereal and pseudocereal flours to facilitate a better raw material choice. It was observed that especially quinoa, buckwheat and teff are high in essential nutrients, such as protein, minerals and folate. In addition the potential of functional ingredients such as inulin, β-glucan, HPMC and xanthan to improve loaf quality were evaluated. Results show that these ingredients can increase loaf volume and reduce crumb hardness as well as rate of staling but that the effect diverges strongly depending on the bread formulation used. Furthermore, fresh egg pasta formulations based on teff and oat flour were developed. The resulting products were characterised regarding sensory and textural properties as well as in vitro digestibility. Scanning electron and confocal laser scanning microscopy was used throughout the thesis to visualise structural changes occurring during baking and pasta making
