Enhancing the Hodgkin-Huxley Equations: Simulations Based on the First Publication in the Biophysical Journal.

The experiments in the Cole and Moore article in the first issue of the Biophysical Journal provided the first independent experimental confirmation of the Hodgkin-Huxley (HH) equations. A log-log plot of the K current versus time showed that raising the HH variable n to the sixth power provided the best fit to the data. Subsequent simulations using n(6) and setting the resting potential at the in vivo value simplifies the HH equations by eliminating the leakage term. Our article also reported that the K current in response to a depolarizing step to ENa was delayed if the step was preceded by a hyperpolarization. While the interpretation of this phenomenon in the article was flawed, subsequent simulations show that the effect completely arises from the original HH equations.

Ireland's Decade of Commemoration: A Round Table

Beginning with last year’s centennial of the passage of the Third Home Rule Bill, Ireland commenced an extraordinary “Decade of Commemorations,” during which the entire island will recall the anniversaries of crucial historic events: the Dublin Lock-out, the Easter Rising, the “Ulster Sacrifice” of the Somme, Partition, and the Irish Civil War, to name a few. The high-profile public history that will be crafted to mark these events is likely to set the received narrative of the events for another century—and, in turn, will enter the interdisciplinary intellectual project of Irish Studies itself. With the special assistance of Dr. Mike Cronin, New Hibernia Review gathered four scholars (two historians, a literary scholar, and a social anthropologist) to discuss the implications, opportunities, and perils of the Decade of Commemorations. They conducted their discussion by e-mail over the summer of 2013.

A warrior nation

Under Prime Minister John Howard, Australia today appears to have turned away from Asia, returning to a Western oriantation. Has racial invasion fear, once expressed in the 'White Australia' policy, been the determinant of relations with Asia? I argue, in contrast, first, that invasion fear preceded race fear and, second, that Australia was unlucky, in coming to nationhood during the eras of Social Darwinism and New Imperialism, scaling ideas of race citizenship into its national formation. It was unlucky to associate national 'manhood' with Gallipoli and war, making the national tradition expeditionary nationalism, or ANZAC. War is central in national memory and public patriotism, primarily because war has been carried out overseas rather than through fighting on Australian soil, and the devastation of Australian cities. Even after the retreat of Western empires in Asia, and of racial ideology, why has this romantic and foolish view of war as an expression of the nation persisted? Paradoxically, Australians romanticise war even though, after 1788, there has been no other invasion of a continent which is harder to invade than it is to defend.

Greek shipping and the crisis of the 1980's

In 1982, Greek shipping plunged into a severe crisis: the size of the fleet declined dramatically and over 30% of the fleet was laid-up. catapulting many shipping companies into bankruptcy. The causes of the crisis were: The world recession, leading to regulation, protectionism, subsidization. and the growth of new competition in the tramp shipping market. The erosion of the cost differential between Greek shipping and other maritime nations of the world. The specialization and containerization of the world fleet. The old age and other characteristics of the Greek fleet, which exacerbated the crisis. Greek shipping, with its long history and the expertise, diligence, and supreme opportunism of its dynamic shipowners, will survive the crisis.

Visions of Utopia

Since 1949, propaganda posters have been produced in China as a visual language to unite the masses. Posters and billboards portraying images of youth in minority costumes, traditional paper cuts and China’s abundant workforce engaged in modernisation were meant to unite the masses through ‘revolutionary realism with revolutionary romanticism’. These images offer interesting insight into Mao’s version ‘socialist utopia’. With the opening of China to foreign investment and trade in 1979, the vision of a ‘socialist utopia’ has changed once again. Propaganda posters are replaced with large-scale billboards featuring luxury cars, clothing and products from the West. In order to illustrate this change, artists from Deakin University in Melbourne, Australia, Lisa Scharoun (Lecturer of Graphic Design) and Frances Tatarovic (Lecturer of Photography), have created a series of ‘advertisements’ that utilize similar themes of Maoist era propaganda posters with the infusion of the glossy characteristics of luxury fashion advertising. The images reference techniques and the visual language of contemporary western commercial fashion photography. Within the artworks, the past and present visual culture of China is juxtaposed to create a dialogue between the icons of the Maoist vision of a socialist utopia and the contemporary visual icons of fashion and luxury advertising.

Soldier settlement after World War One in south western Victoria

This thesis addresses the physical aspects of farming on soldier settlement blocks in south west Victoria. The undeveloped land, high establishment costs, stock losses through animal diseases and lack of managerial skills all contributed to the settlers' inability to meet their financial commitments. These factors are analysed, as are the effects of declining rural commodities prices during the 1920s and 1930s. In addition, the relationship between the settlers and the successive administrative agencies is examined. The scheme was administered by the Closer Settlement Board from its inception until 1932 and much of the discussion during this period concerns the interaction between settler and inspector. Soldier settlement after World War One represented one of the last attempts to create a large body of 'yeoman' farmers. From the early 1920s there was an increasing dichotomy between the 'yeoman' and the 'managerial' ideologies. This dichotomy placed additional pressure on soldier settlers who were expected to be 'efficient' without adequate finances. In the post C.S.B. era, the focus shifts to the attempts by the Closer Settlement Commission to salvage the scheme and its greater understanding of the problems faced by the settlers. While this part of the thesis necessarily becomes more political, the physical and financial environment in which the soldier settlers worked was still an important factor in their success or failure. Unlike the C.S.B. which tended to blame soldier settlers for their situation, the Commission acknowledged that settlers' ability to succeed was often constrained by circumstances beyond their control. Under the latter administration, instalments were written off, additional land was allocated and finally the blocks were revalued to guarantee the men at least some equity in their farms. Those settlers who had survived until these changes were instituted received a 'successful outcome of their life's work'.

Science education in primary schools in a state of change

Through a longitudinal study of one teacher's science teaching practice set in the context of her base school, this thesis records the effects of the structural and policy changes that have occurred in Victorian education over the past 6-7 years - the 'Kennett era'. Initially, the purpose of the study was to investigate the teacher's practice with the view to improving it. For this, an action research approach was adopted. Across the year 1998, the teacher undertook an innovative science program with two grades, documenting the approach and outcomes. Several other teachers were involved in the project and their personal observations and comments were to form part of the data. This research project was set in the context of a single primary school and case study methodology was used to document the broader situational and daily influences which affected the teacher's practice. It was apparent soon after starting the action research that there were factors which did not allow for the development of the project along the intended lines. By the end of the project, the teacher felt that the action research had been distorted - specifically there had been no opportunity for critical reflection. The collaborative nature of the project did not seem to work. The teacher started to wonder just what had gone wrong. It was only after a break from the school environment that the teacher-researcher had the opportunity to really reflect on what had been happening in her teaching practice. This reflection took into account the huge amount of data generated from the context of the school but essentially reflected on the massive number of changes that were occurring in all schools. Several issues began to emerge which directly affected teaching practice and determined whether teachers had the opportunity to be self-reflective. These issues were identified as changes in curriculum and the teaching role, increased workload, changed power relations and changed security/morale on the professional context. This thesis investigates the structural and policy changes occurring in Victorian education by reference to documentation and the lived experiences of teachers. It studies how the emerging issues affect the practices of teachers, particularly the teacher-researcher. The case study has now evolved to take in the broader context of the policy and structural changes whilst the action research has expanded to look at the ability of a teacher to be self-reflective: a meta-action research perspective. In concluding, the teacher-researcher reflects on the significance of the research in light of the recent change in state government and the increased government importance placed on science education in the primary context.
