Product placement, also referred to as stealth advertising, raises important questions when it comes to television because a far larger audience views television than movies. Product placement in newscasts is even more controversial. Television news is expected to be free of persuasive attempts and provide citizens with basic information that is of public importance. Yet, product placement blurs the line between journalism and commercial promotion, thus destroying the integrity of the news. Product placement in newscasts raises ethical questions about the effect it has on viewers, provided that they do not realize that they are presented with commercials, framed as news story. Yet, this paper argues that, since viewers focus on the actual news and do not elaborate consciously on the advertised product or brand, product placement in newscasts has little effect on their brand recall. To support this hypothesis the paper compares brand recall from product placement and commercials. Results revealed that this hypothesis is partially true. Important discovery from this study is the fact that product placement directly affects news credibility.

The banded elm bark beetle, Scolytus schevyrewi, was first observed in Canada in Alberta in 2006. In 2007, it was found in Manitoba and Saskatchewan. Its hosts include the American elm and so, it has the potential to transmit Dutch elm disease. The beetle was studied in six communities in 2009–2011 in Manitoba and Saskatchewan to learn about its biology in the Prairies. Baited sticky traps revealed that the adult flight period is from June until October, with a peak in late summer. Unbaited sticky traps and trap logs revealed that stressed Siberian elm is the preferred host. Although S. schevyrewi larvae overwintered successfully, 15% of the overwintering individuals emerged in the spring. The main impact of S. schevyrewi is expected to be the killing of stressed Siberian elms. Such trees should be removed to avoid population outbreaks that might result in attacks on healthy Siberian and American elms.

A genetic catalogue was generated from expressed sequence tags (ESTs) from the pathogenic filamentous fungus Ophiostoma novo-ulmi. Rather than full sequencing of the entire genome, fragments of each gene being actively expressed at a specific point in time were catalogued and annotated for identity and function. This catalogue represents a resource of considerable depth for the purposes of gene discovery, genetic regulation, protein expression, pathogenicity, and growth state studies. An online database was generated to serve as a powerful tool for downstream applications, facilitating and enhancing future research in all of these important areas of fungal biology. The ascomycetous fungus Ophiostoma novo-ulmi represents an excellent model organism for genetic experimentation. A diversity of physiological functions, including dimorphism, pathogenicity, melanin biosynthesis, and glycoprotein secretion at high levels mean that principles elucidated from this fungus are likely of broad application. Ophiostoma novo-ulmi has been identified as the causative agent of Dutch elm disease, which has become an economic and horticultural pandemic in North America. As a result, the mechanisms of host-pathogen interaction of this fungus are of particular interest. Initial attempts at disruption of pathogenicity, most commonly by disruption of single genes identified as potential pathogenicity factors, have met with little success. As our understanding of the complexity and co-ordination of proteins involved with host-pathogen interaction deepens, the discovery of a single dominant pathogenicity gene is becoming increasingly unlikely. As such, a broader genomics approach was employed to work towards identification of groups, or networks of genes that operate in a concerted manner, regulating pathogenicity or parasitic fitness. A low redundancy library was constructed from Ophiostoma nova-ulmi complementary DNA, producing a total of 4386 readable expressed sequence tags (ESTs) from 5760 clones. Of these, 2093 sequences matched with sequences found in public databases while 2293 represented orphan sequences. Of the sequences in the former group, 1761 sequences matched with known proteins while 332 sequences matched with hypothetical/predicted proteins. Sequences matching known proteins included 880 singletons, corresponding to 49.97 % of the ESTs in this category. Extrapolating this proportion to the sequences matching hypothetical proteins estimated the number of singletons in this category to be 166. Similarly, 1835 orphan sequences were estimated to contain 917 unique sequences. Singletons matching entries in public databases (n=880) were manually annotated into functional categories as established by the Munich Information Centre for Protein Sequences (MIPS). Metabolism (21%), Protein Synthesis (10%), Subcellular Localization (10%), Biogenesis of Cell Components (8%), and Transcription (8%) categories were the most highly represented.

Functional programming has long been used in academia, but has historically seen little light in industry, where imperative programming languages have been dominating. This is quickly changing in web development, where the functional paradigm is increasingly being adopted. While programming languages on other platforms than the web are constantly competing, in a sort of survival of the fittest environment, on the web the platform is determined by the browsers which today only support JavaScript. JavaScript which was made in 10 days is not well suited for building large applications. A popular approach to cope with this is to write the application in another language and then compile the code to JavaScript. Today this is possible to do in a number of established languages such as Java, Clojure, Ruby etc. but also a number of special purpose language has been created These are languages that are made for building front-end web applications. One such language is Elm which embraces the principles of functional programming. In many real life situation Elm might not be possible to use, so in this report we are going to look at how to bring the benefits seen in Elm to JavaScript.

Experimental investigations of high temperature industrial processes, for example the melting and smelting processes taking place inside furnaces, are complicated by the high temperatures and the chemically reactive environment in which they take place. Fortunately, mathematical models can be used in conjunction with the limited experimental results that are available to gain insight into these high temperature processes. However, mathematical models of high temperature processes require high temperature material properties, which are difficult to measure experimentally since container materials are often unable to withstand high enough temperatures, and sample contamination often occurs. These difficulties can be overcome by employing containerless processing techniques such as electromagnetic levitation melting to allow for characterisation of high temperature material properties. Efficient design of electromagnetic levitation cells is challenging since the effects of changes in coil design, sample size and sample material on levitation force and sample temperature are not yet well understood. In this work a numerical model of the electromagnetic levitation cell is implemented and used to investigate the sensitivity of levitation cell operation to variations in coil design, sample material and sample size. Various levitation cell modelling methods in literature are reviewed and a suitable model is chosen, adapted for the current application, and implemented in Python. The finite volume electromagnetic component of the model is derived from Maxwell’s equations, while heat transfer is modelled using a lumped parameter energy balance based on the first law of thermodynamics. The implemented model is verified for a simple case with a known analytical solution, and validated against published experimental results. It is found that a calibrated model can successfully predict the lifting force inside the levitation cell, as well as the sample temperature at low coil currents. The validated model is used to characterise the operation of a levitation cell for a number of different sample materials and sample sizes, and for variations in coil geometry and coil current. The model can be used in this way to investigate a variety of cases and hence to support experimental levitation cell design. Based on model results, a number of operating procedure recommendations are also made. / Dissertation (MEng)--University of Pretoria, 2016. / Mechanical and Aeronautical Engineering / MEng / Unrestricted
