Play it again, Sam : How journalists cashed in on Youtube's favourite koala

The world was captivated when footage of a badly burnt koala drinking water from a Victorian firefighter's bottle was uploaded to You Tube in February 2009. When the story of "Sam the Koala" was adopted by the mainstream media, recombinant themes were used to construct her story - from heroism and patriotism to villain vs victim and romance. While scholars have examined the changing role of the journalist in a converged world and the rise of "soft" news, this paper focuses on the way journalists create disjointed narratives around You Tube footage to extend a story s lifespan. We call these new narrative forms "fractured fairy tale news" to describe this emerging phenomenon of convergence culture. Further, we suggest that news media exploit the YouTube community for their own commercial gain and conclude that the fractured fairy tale style is a poor vehicle for the future of news.

Impact of the extended family on microenterprise growth in Ghana : a case study of Accra

This study examines the extended family's impact on microenterprise growth at the individual level, where microenterprise operators have some control over constraints affecting their operations. Beyond the individual level, microenterprise operators have little control over constraints such as government policies and regulations, competition from import-substitution industries and exploitation by corrupt officials. Therefore, it is at the individual level that the extended family serves as a crucial parameter of microenterprise growth and the success with which MEs graduate from the informal sector into the mainstreams of small business. Within this domain, this author has examined the extended family and found that there is a need for policy makers and MED administrators to adopt a more culturally sensitive approach to microenterprise growth if the extended family is to be engaged as a partner in their efforts to support microenterprises as a source of income and employment generation, A central question posed is why most writers on microenterprise activities in Ghana have neglected the extended family as a factor that should be considered in the design of microenterprise growth strategies and policies? The answer to this question was explored in the process of data gathering for this thesis and the results are presented here, especially in chapter 3 below. Suffice it to note here that this neglect has many roots, not least of which is the proclivity of mainstream economics, modern administration practice and the objectivity of double entry accounting based documentation procedures to focus on measurable growth in the formal sectors of the economy and structural constraints such as the lack of finance, lack of market demand, lack of access to technology and government regulations. Consequently, a noticeable trend among these writers is that they rightly advocate finance be made accessible to microenterprises, however, few question whether the finance is effectively used towards microenterprise growth. This issue is crucial in the face of evidence from this study which shows that finance accessed towards microenterprise growth is often put to other uses that negate growth thus keeping microenterprises within the bounds of the informal sector as against graduating out of the informal sector. As a result, these writers have neglected the intimate relations between the extended family and microenterprises, and most importantly, the constraint that the extended family inflicts on microenterprise growth at the individual level of activity. This study, by targeting the growth of the individual microenterprise in the socio-cultural context in which this growth must be achieved, has highlighted the constraint that the extended family does pose on MED. However, the study also shows that these constraints are important not because there is anything inherently wrong with the extended family, but because the socio-economic and policy environment is not consistent with the positive role that the extended family can and should play in the graduation of microenterprises from the informal to the formal sector of the economy in Ghana.

Are OECD stock prices characterized by a random walk? Evidence from sequential trend break and panel data models

This paper examines whether stock prices for a sample of 22 OECD countries can be best represented as mean reversion or random walk processes. A sequential trend break test proposed by Zivot and Andrews is implemented, which has the advantage that it can take account of a structural break in the series, as well as panel data unit root tests proposed by Im et al., which exploits the extra power in the panel properties of the data. Results provide strong support for the random walk hypothesis.

Changes in the composition of the extracellular matrix in patellar tendinopathy

Objective: To compare the chemical levels and mRNA expression of proteoglycan and collagen in normal human patellar tendons and tendons exhibiting chronic overuse tendinopathy.

Methods: Sulfated glycosaminoglycan and hydroxyproline content were investigated by spectrophotometric measurement using papain-digested samples. Deglycosylated proteoglycan core proteins were analysed by Western blot using specific antibodies. Total mRNA isolated from samples of frozen tendons was assayed by relative quantitative RT-PCR for decorin, biglycan, fibromodulin, versican, aggrecan, and collagens Type I, II and III and normalised to glyceraldehyde-3-phosphate dehydrogenase.

Results: There was a significant increase in sulfated glycosaminoglycan content in pathologic tendons compared to normal. This was attributed to an increased deposition of the large aggregating proteoglycans versican and aggrecan and the small proteoglycans biglycan and fibromodulin, but not decorin. Aggrecan and versican were extensively degraded in both normal and pathologic tendons, biglycan was more fragmented in the pathologic tendons while predominantly intact fibromodulin and decorin were present in normal and pathologic tendons. There was a greater range in total collagen content but no change in the level of total collagen in pathologic tendons. There were no significant differences between the pathologic and normal tendon for all genes, however p values close to 0.05 indicated a trend in downregulation of Type I collagen and fibromodulin, and upregulation in versican and Type III genes in pathologic tissue.

Conclusion: The changes in proteoglycan and collagen levels observed in patellar tendinopathy appear to be primarily due to changes in the metabolic turnover of these macromolecules. Changes in the expression of these macromolecules may not play a major role in this process.

Management of cardiovascular diseases with micro systems and nanotechnology

Cardiovascular diseases are the leading cause of death and morbidity in industrialized nations and are becoming an urgent health problem for all nations due to the unstoppable trend of an ageing and obese population. Due to the rapid development of micro total analysis systems (μTAS) and nanotechnology in recent years, they will play an important role in the diagnosis, management, and therapy of cardiovascular diseases. It is envisaged that the micro and nanotechnologies developed for treating other diseases shall be explored for cardiovascular applications to reduce the research effort required for commercializing the devices and drugs to meet the increasing demand of the cardiovascular patients.

From play to poetics

An expedient approach towards organizing ideas and drafting at the sentence-level, play with phrase structures in the Vygotskyan tradition demonstrates the often unexploited possibilities afforded to composition students through creative experiential learning; circumvents prescriptive pedagogies; and makes explicit a student's tacit awareness of standard grammars and more valued rhetorical conventions.

An investigation of the influences on children's active free-play

This research examined the influences on children's (6-12 years) active free-play. The findings suggest that there are a number of strategies that focus on individual, social and physical environmental factors that have the potential to be successful in creating opportunities for children to be physically active in their free-time.

Intra-ASEAN FDI : trend, determinants and analytical issues

One of the significant economic developments in the Asia Pacific region during the 1980's has been the phenomenal increase in intra-ASEAN foreign direct investment (FDI) flows. There are two types of intra-ASEAN FDI flows : out-sourcing and the opportunity to gain access to the host country's modern infrastructural and information network.
