Observations on the effects of caged carp culture on water and sediment metal concentrations in Lake Kasumingaura, Japan

The concentrations of 24 elements in the sediment and associated water column were monitored at two sites, one an area of intensive cage culture of carp, the other a wild site far from known cage culture areas, in Lake Kasumigaura, Japan, between September 1994 and September 1995. The concentrations of most elements in Lake Kasumigaura are mostly sub-parts per billion, except those for Ca, Fe, K, Mg, Na, P, and Si. The concentrations of Cd, Co, Cu, Mn, Ni, Pb, V, and Fe in Lake Kasumigaura are higher than the values in Lake Mashu, Lake Shikotsu, and Lake Biwa, and comparable to the levels in open ocean. Statistically significant differences in metal concentrations were observed between the culture and wild sites, with metal concentrations consistently higher at the culture site. Although cage culture of carp in the Lake Kasumigaura system may be causing localized increase in metal concentrations in the sediments, we must treat the results with caution, since the concentrations of metals observed in the sediments in 1995 were lower than those observed in 1979 for all metals at both sampling sites. In conclusion, further study of the concentrations of metals in the lake as a whole must be undertaken before the differences between the culture and wild sites can be proved, or disproved, to be the result of carp culture.

Switching on the chronometer of history : communism, postcommunism and heritage

The destruction of monuments accompanying the fall of Communism ignited debates about preservation of manifestations of a hated regime. While heritage professionals called for their preservation as ‘historical documents’, many monuments were destroyed or removed. Yampolsky sees anti-Communist iconoclasm as a rejection of the totalitarianism of time embodied in Communist monuments. These ‘intentional monuments’ were intended to ‘negate the march of time and oppose to it the permanence of human action’. They demonstrated the alleged end of history in a classless utopia.

Iconoclastic acts against these monuments involved the crossing of ‘the invisible boundaries of the sacral zone surrounding monuments, switching on the chronometer of history’. In doing so, iconoclasts provide the conditions for reassertion of heritage practices: heritage requires a sense of the flow of time, a difference between past, present and future.

Having restarted the chronometer of history, a society is forced to assess where it stands in relation to its past. Will it continue on a path of ‘wilful forgetting’, or seek to confront the past? The danger of wilful forgetting is the creation of nostalgia. Alternatively, preservation of places of memory helps processing of the past required for movement into the future. ‘One need only consider the way in which Berliners tore down the hated Berlin Wall in the aftermath of 1989’, Fulbrook writes, ‘to understand the desire to rid the landscape of a hated excrescence, a symbol of a rejected political past. But…for those who come after, the effort of historical imagination is all the greater for lack of a topography of experience’.

Heritage preservation can produce a ‘topography of experience’, through which the experience of Communism is examined. Reassertion of a humanistic historical time through heritage practices reveals the arrogant futility of utopian projects seeking to bring history to an end.

Revised stratigraphy of the Blanchetown Clay, Murray Basin: age constraints on the evolution of paleo Lake Bungunnia

Paleo Lake Bungunnia covered more than 40 000 km2 of southern Australia during the Plio-Pleistocene, although the age and origin of the lake remain controversial. The Blanchetown Clay is the main depositional unit and outcrop at Nampoo Station in far-western New South Wales provides the most continuous lacustrine section preserved in the basin. Here the Blanchetown Clay represents the maximum lake fill and comprises: (i) a basal well-sorted sand with interbedded clay (Chowilla Sand), representing initial flooding at the time of lake formation; (ii) a thick sequence of green-grey clay comprised dominantly of kaolinite and illite, with the apparently cyclic occurrence of illite interpreted to represent cool and dry glacial climatic intervals; and (iii) a 2.6 m-thick sequence of finely laminated silt and silty clay, here defined as the Nampoo Member of the Blanchetown Clay. New magnetostratigraphic data constrain the age of the oldest lake sediments to be younger than 2.581 Ma (Matuyama-Gauss boundary) and probably as young as 2.4 Ma. This age is significantly younger than the age of 3.2 Ma previously suggested for lake formation. The youngest Blanchetown Clay is older than 0.781 Ma (Brunhes-Matuyama boundary) and probably as old as 1.2 Ma. The Nampoo Station section provides a framework for the construction of a regional Plio-Pleistocene stratigraphy in the Murray Basin.

Transforming history and myth: on the mutuality and separation of shared narratives in Eastern Tibet

Questioning the distinction between ‘cold’ and ‘hot’ societies, and an implied separation between myth and history, anthropologists have increasingly urged for an understanding of both myth and history as equally valid modes of shared social consciousness. This article takes up this point of view by referring to a written history of Lhagang, a town in Eastern Tibet; a history that appears to have the transformative content and oral circulation of myth. Using Lévi-Strauss’ structural analysis of myth and Santos-Granero's concept of topograms to demonstrate the mythemes that derive from the written history and circulate among Lhagang Tibetans, the article argues that, within the political and cultural context of Lhagang, myth and history shift in and out of indigenous categories even while being categorically distinct.

Holocene record of Tuggerah Lake estuary development on the Australian east coast: sedimentary responses to sea-level fluctuations and climate variability

We investigated the Holocene palaeo-environmental record of the Tuggerah Lake barrier estuary on the south-east coast of Australia to determine the influence of local, regional and global environmental changes on estuary development. Using multi-proxy approaches, we identified significant down-core variation in sediment cores relating to sea-level rise and regional climate change. Following erosion of the antecedent land surface during the post-glacial marine transgression, sediment began to accumulate at the more seaward location at ~8500. years before present, some 1500. years prior to barrier emplacement and ~4000. years earlier than at the landward site. The delay in sediment accumulation at the landward site was a consequence of exposure to wave action prior to barrier emplacement, and due to high river flows of the mid-Holocene post-barrier emplacement. As a consequence of the mid-Holocene reduction in river flows, coupled with a moderate decline in sea-level, the lake experienced major changes in conditions at ~4000. years before present. The entrance channel connecting the lake with the ocean became periodically constricted, producing cyclic alternation between intervals of fluvial- and marine-dominated conditions. Overall, this study provides a detailed, multi-proxy investigation of the physical evolution of Tuggerah Lake with causative environmental processes that have influenced development of the estuary.

Student perspectives on the value of experiential learning in history

This paper is a reflective study of experiential learning as an American history teaching-tool. It is based on a survey of students who took a University of Melbourne study tour to the United States in the years from 2001–2011. This survey asked students to identify the tour’s long-term outcomes. The responses showed that students believed the study tour was beneficial academically, and that it also opened up employment opportunities. However, the most significant benefit identified by the students was positive social outcomes—in other words, the friends they made on the tour and the professional networks they formed. The conclusion we drew from these results was that students believe that experiential learning has a legitimate place in history curriculums, and that it is an antidote to the loneliness they feel in traditional classroom settings.

Samurai in the surf : the arrival of the Japanese on the Gold Coast in the 1980s

Samurai in the Surf explores the history of Japanese investment in the 1980s, following a money-trail that leads back to a ballooning Japanese economy and a colorful array of investment sources. The book also explores the local community's views of this unprecedented stream of foreign investment and provides a convincing illustration of the links between 1980s Queensland and Pauline Hanson's One Nation movement of the 1990s.

`Out on the borderlands`: Time, generation and personal agency in women`s lives

What tools can we use in attempting to understand the recurring patterns of some girls’ early school leaving and consequent exclusion from well-paid employment? From which disciplinary fields can we take them? Using Bourdieu’s concept of the ‘scholastic point of view’ - the inherent intellectual bias of a discipline, in his case sociology - as a springboard, we suggest that if one turns to different ‘fields’, approaches might be found which point towards differing perspectives. This article brings Bourdieu into dialogue with the work of feminist historians and their conceptual tools. Carolyn Steedman’s notion of the politics of envy and Sally Alexander’s appropriation from psychoanalysis of the idea of repetition offer generative ways of exploring the ‘unthought categories of thought which delimit the thinkable and predetermine the thought’ (Bourdieu and Wacquant, 1992: 40). In their focus on gender, they have much in common with feminist sociologists’ responses to Bourdieu’s work, suggesting that a gendered ‘perspective’ offers a way of avoiding the ‘singular viewpoint’ inherent in any one discipline.
