Democracy Sausage with Mark Kenny: In the national interest
No full textOn this special 100th episode of Democracy Sausage, we’re joined by Frank Bongiorno, Jacinta Carroll, Marija Taflaga, and Mark Kenny to talk Australian attitudes towards COVID-19 surveillance, security agencies on social media, and accountability for former political figures. What do Australian attitudes towards surveillance amidst the COVID-19 crisis suggest about trust in society? After weeks of icy diplomatic exchanges, what is the Australian government’s long-term goal for its relationship with Beijing? And why are Australia’s security agencies taking to social media? On the 100th episode of Democracy Sausage, we’re joined by national security expert Jacinta Carroll, historian Professor Frank Bongiorno, regular podleague Dr Marija Taflaga and, taking a break from his holiday to appear as guest, Professor Mark Kenny
Impact, language communities and archaeological schools: British Archaeologists and Italian Neolithic studies
No full textNew research on the <i>terramare</i> of northern Italy
No full textThe north Italian Bronze Age culture–the terramare–has recently been celebrated in a splendid exhibition at Modena, and new catalogues, research and the re-opening of old excavations. Mark Pearce discusses the relevance of the old ideas in the light of new data.</jats:p
Hard cheese: upland pastoralism in the Italian Bronze and Iron Ages
No full textBy moving livestock to summer farms, fodder at the home base is saved but the milk and other animal products produced during the animals’ absence are no longer immediately available to those left at the home base. In this paper I shall explore the economic implications of the use of summer farms, in particular the effect on carrying capacity, on the number of livestock which can be over-wintered, and on the use of the milk produced while the animals are at the summer grazing lands.
I then explore archaeological evidence from the Bronze and Iron Ages of the Italian uplands (Apennines and Alps). I argue that the production of hard cheese, which converts milk into an easily conservable and transportable commodity, is key to the expansion of summer farms in the Bronze Age of Italy. Cheese production is an essential part of models for the pastoral use of Mediterranean uplands in prehistory but it is commonly held that in the Alps the production of hard cheese only begins in the Middle Ages. I examine the literary and archaeological evidence for the prehistoric production of hard cheese and argue that its production in prehistory is the most parsimonious explanation for the summer use of high mountain pastures and thus for the origins of the Alpwirtschaft economy in the southern Alps
Democracy Sausage with Mark Kenny: The politics of hope in a pandemic
No full textOn this week’s fry up of politics and public affairs, our outstanding panel of John Hewson, Quentin Grafton and Marija Taflaga join us to talk about the COVID-19 aged care inquiry, tensions over state border closures, and whether or not a coronavirus vaccine should be mandatory. It was a “week of hope” in the words of Australian Prime Minister Scott Morrison, after signing a letter of intent to access the promising Oxford University coronavirus vaccine and falling infection numbers in Victoria. So after weeks of restrictions in Victoria following its second wave outbreak, is this week another turning point in Australia’s coronavirus response? Should Aged Care Minister Richard Colbeck face sanctions for failing to recall how many aged care residents have died from the virus in a Senate Inquiry? And is making a COVID-19 vaccine compulsory essential to ensure community safety in the wake of the pandemic? With Mark Kenny on a well-earned break, Martyn Pearce fires up the barbeque this week, joined by former Opposition Leader Dr John Hewson, Crawford School’s Professor Quentin Grafton, and regular podleague Dr Marija Taflaga
A biographical study of men with chronic low back pain
No full textLow back pain is a common condition that will affect 80% of the population at some point in their lives. For the majority of people the pain and associated disability will be resolved and they will resume normal activities. For a small proportion of this group however, the condition will remain unresolved with associated long-term pain and disability; this is termed chronic low back pain (CLBP). The costs associated with CLBP are high both physically and emotionally for the individual, and in terms of the economic burden placed on society pertaining to healthcare costs and lost productivity.CLBP is a multifaceted condition. Whilst a biopsychosocial model of care, as opposed to the traditional biomedical model, is advocated as the best approach for its management it has been suggested that the impact on the self-concept and identity of individuals with this condition has not been fully explored or addressed.This study employed a biographical approach with the aim of understanding the impact on the lives and identities of men living with CLBP. Five men were recruited and in-depth interviews were undertaken which were audio-recorded, transcribed verbatim and analysed thematically.The identity of all the participants in the study had been affected by CLBP. Clear themes emerged that included feeling defined by their CLBP, experiencing feelings of frustration and anger, the inability to retain their masculine role, the impact on fatherhood, public and private identities, physicality and feeling a liability or burden to others. The support received from significant others was also highlighted. The participants detailed how exercise and education were major aspects in the management of their condition whilst resilience and the use of humour were also very apparent in their narratives as mechanisms to enable them to cope with CLBP
Development of the boundary conditions required for simulating a wave tank using smoothed particle hydrodynamics
No full textSmoothed Particle Hydrodynamics, SPH, is a Lagrangian method that has been applied to a number of fields including maritime applications. However little work has been done concerning the simulation of the motion of ships' hulls. A weakness of SPH is in the modelling of boundaries, both permeable and impermeable. This thesis investigates some of the latest SPH methods used to simulate these boundaries. Particular emphasis is placed upon the development of an approach that idealises the permeable inflow and outflow boundaries of a domain that are required to simulate the boundaries of a wave tank.In the method presented the inflow boundary has been designed such that it can also generate waves. This allows for the simulation of a ship hull subject to head waves. The inflow boundary is also capable of creating a mean flow speed along with the wave generation. The outflow boundary serves as both a plane which allows particles that have crossed it to be removed and also incorporates a sponge layer that is designed to damp out incoming waves and prevent any unphysical wave reflection. These developments, used together, allow a small section of a wave tank to be simulated, this requires a minimum of computational resources.Each new development has been tested against published data from experiments or numerical simulation. The computational models discussed in this thesis compare the performance of the new approach against experimental data and simulations using both classic SPH and Reynolds-Averaged Navier-Stokes methods. The wave generation and damping methods have been compared against the motion predicted by the Airy wave theory. The hull motion simulations have been compared against Wigley hull experimental data
