Mixed Salmonella Infection: A Case Series From Pakistan, Binish Arif Sultan, Naima Fasih, Saba Qaiser, Erum Khan, Afia Zafar, Seema Irfan

Department of Pathology and Laboratory Medicine

Enteric fever remains a major health problem in the developing world, including Pakistan. Poor sanitation and hygienic conditions are the major predisposing factors. Salmonella infection with different strains in the same patient has rarely been reported previously. We are reporting two cases of bacteraemia with simultaneous detection of two strains of Salmonella in a single episode of infection. In both the cases, 2 different serotypes of Salmonella were causing bacteraemia leading to fever. In highly endemic area, one must be aware of mixed Salmonella infections as inappropriate diagnosis of such infections may lead to treatment failure.

Evolution Of High Tooth Replacement Rates In Sauropod Dinosaurs, Michael D. D'Emic, John A. Whitlock, Kathlyn M. Smith, Daniel C. Fisher, Jeffrey A. Wilson

Earth, Environment & Sustainability: Faculty Publications

Background: Tooth replacement rate can be calculated in extinct animals by counting incremental lines of deposition in tooth dentin. Calculating this rate in several taxa allows for the study of the evolution of tooth replacement rate. Sauropod dinosaurs, the largest terrestrial animals that ever evolved, exhibited a diversity of tooth sizes and shapes, but little is known about their tooth replacement rates.

Methodology/Principal Findings: We present tooth replacement rate, formation time, crown volume, total dentition volume, and enamel thickness for two coexisting but distantly related and morphologically disparate sauropod dinosaurs Camarasaurus and Diplodocus. Individual tooth formation time was determined …

My Worst Ever Night At The Best School Ball Ever : Creating Taboo Theatre For Teenagers, Jeremy F. Rice

Theses: Doctorates and Masters

A prank with a goat goes horribly wrong, a photo of a girl pissing in a pot plant is widely circulated, and everyone finds out about the boy in a sexual relationship with a teacher. At the heart of the play are teenagers, armed with mobile phones, trying to find their way in a contradictory and confusing world.

The creative development of School Ball centred on practice-based …

Homing : Poetry ; &, An Essay On The Poetic Leap In The Late Work Of R.S. Thomas, Shevaun Cooley

Theses: Doctorates and Masters

Homing, as a collection, speaks to the capacity and yearning to navigate our way towards something we might call home. In animal behaviour, this seems like an instinct, hard-wired to the body. It is something I envy. By comparison, the instinct, in human behaviour, feels muffled and complicated.

These poems move between two places in which I feel ‘at home’, whatever that means: the south-west of Western Australia, where I was born and raised, and the north-west of Wales, where I lived for a time, and find myself returning to, drawn not by blood, but by longing, and a deep …

A Model Of Management Learning For Occupational Therapists In Small Business In Australia, Jeannine Millsteed

Theses: Doctorates and Masters

This research sought to identify factors that contribute to occupational therapists developing management competencies when they become small business owners providing professional clinical services. This is an important for several reasons and precipitated by the Australian government’s introduction of incentives that encourage health professions to move from employment in public hospitals into the private sector, coupled with a recognition that occupational therapists receive no formal business training in their professional education, and the reported high levels of business failure in the small business sector. A review of the literature established the value of small business to the Australian economy, growth …

The Biology And Ecology Of Epinephilidae Speciea And Their Implications To Fisheries Management, Jason R. How

Theses: Doctorates and Masters

This thesis examines the biological and ecological aspects of members of the globally exploited Epinephilidae with reference to fisheries management and in particular the use of closures. The leopard coralgrouper Plectropomus leopardus is a common reef fish throughout the Indo-Pacific region and a major target of both commercial and recreational fisheries. There has been limited research on this species in the eastern Indian Ocean, where there are only two populations. An examination of the species found a number of significant biological differences to their eastern Australian con-specifics. Most noticeable was the strong size-related cue over their protogynous sex change. The …

Evaluating Residential Satisfaction With An Innovative Dual Water Supply System In Water Sensitive Urban Development, Raju S. Dhakal

Theses: Doctorates and Masters

The Australian water industry is facing two major challenges: a rise in water demand due to a growing population and a decrease in rainfall availability due to a drying climate. This situation has triggered a re-evaluation of traditional water schemes and promoted consideration of alternatives for sustainable urban water management. One possibility is to replace drinking water usage in garden and outdoor irrigation with non-potable groundwater. This could save almost half of the water supplied in the residential sector, which is the biggest consumer of scheme water in most Australian cities. A major hurdle for the success of such fit-for-purpose …

Pax3 Expression, Protein Modifications And Downstream Target Gene Profiling In Melanocytes And Melanoma Cells, Danielle Bartlett

Theses: Doctorates and Masters

PAX3 is a transcription factor. It plays a major role in the development of melanocytes in the embryo. As a result of alternative splicing, the gene gives rise to eight different transcripts which encode proteins that have differing structures and are therefore likely to activate different downstream target genes. The presence of post-translational modifications has also been shown to alter the functions of the proteins.

PAX3 regulates the maintenance of undifferentiated melanoblasts and mediates pathways involved in proliferation, migration and survival. It has been shown to be expressed in melanoblasts, adult melanocytes, naevi and in most melanoma cells. This implies …

Not All That Glitters Is Gold: The Effect Of Attention And Blogs On The Investors' Investing Behaviors, Nan Hu, Yi Dong, Ling Liu, Lee J. Yao

Research Collection School Of Computing and Information Systems

This article investigates the relationship between a firm’s visibility in blogspaces, termed blog exposure, and the cross-sectional stock returns. We show that blog exposure is fundamentally different from the traditional media coverage, and securities with low blog exposure earn higher returns than stocks with high blog exposure. We further illustrate that such an effect is more prominent for stocks with low institutional ownership. Contrary to traditional media coverage, the return premium associated with blog exposure cannot be explained by either the illiquidity hypothesis or the investor recognition hypothesis based on the rational-agent framework. Instead, our results suggest that blog effect …

Comparing Local Models Of Agrarian Transition In China, Qian Forrest Zhang

Research Collection School of Social Sciences

The development of markets and the penetration of capital into agriculture have started the agrarian transition in rural China, which is transforming smallholding, household-based agriculture into various forms of capitalistic production. This again raises in a new historical and social context the long-debated question in the agrarian transition literature: Can family farms survive the onslaught of capitalist agriculture based on wage labor and what shapes the confrontation between family farms and agro-capital? I argue that it is the local political economy—rather than some natural obstacles in agriculture to the penetration of capitalism—that shapes this confrontation and gives rise to a …

The Unraveling Of The Private Consensus, Justin Kh Tse

Research Collection School of Social Sciences

The Asian American Open Letter to the Evangelical Church was a key moment in the unraveling of the private consensus in American evangelicalism in 2013. What I call the “private consensus” is an implied agreement among evangelical Protestants in America that churches, parachurch organizations, and religious institutions should conduct matters privately. In fact, it might go as far as to say that individual Christians should act in private, away from the public eye, especially the media. When Christian matters become public, so the argument goes, they become distorted. Consequently, Christians are encouraged to operate at a “direct and personal” level, …
