Castlemaine Art Gallery and Historical Museum : history and collections

A publication of works from the permanent collection and a history to mark the centenary of the Castlemaine Art Gallery and Historical Museum. The photographs have been produced using superimposed exposures of polarised and non-polarised light; a technique for the optical and digital enhancement of colour saturation, reflection reduction and surface effects in reprography of painting developed by James McArdle.

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.

Using gene-history and expression analyses to assess the involvement of LGI genes in human disorders

Mutations in the leucine-rich, glioma-inactivated 1 gene, LGI1, cause autosomal-dominant lateral temporal lobe epilepsy via unknown mechanisms. LGI1 belongs to a subfamily of leucine-rich repeat genes comprising four members (LGI1–LGI4) in mammals. In this study, both comparative developmental as well as molecular evolutionary methods were applied to investigate the evolution of the LGI gene family and, subsequently, of the functional importance of its different gene members. Our phylogenetic studies suggest that LGI genes evolved early in the vertebrate lineage. Genetic and expression analyses of all five zebrafish lgi genes revealed duplications of lgi1 and lgi2, each resulting in two paralogous gene copies with mostly nonoverlapping expression patterns. Furthermore, all vertebrate LGI1 orthologs experience high levels of purifying selection that argue for an essential role of this gene in neural development or function. The approach of combining expression and selection data used here exemplarily demonstrates that in poorly characterized gene families a framework of evolutionary and expression analyses can identify those genes that are functionally most important and are therefore prime candidates for human disorders.

Family history and the Great War in Australia

The boom in family history that is a hallmark of so much historical activity around the globe over the last three decades is one contributor to the resurgence of interest in the Great War itself. In Australia, as elsewhere in the western world, family history and the resources dedicated to it have been expanding rapidly. This chapter investigates recent practices of family history of the Great War in Australia. Our aim is to examine the role of family history in producing and reproducing knowledge of the Great War within Australian families, and the relationship between the conduct and transmission of family history on the one hand, and the contours of cultural memory on the other.

Evolutionary history and leaf succulence as explanations for medicinal use in aloes and the global popularity of Aloe vera

BACKGROUND: Aloe vera supports a substantial global trade yet its wild origins, and explanations for its popularity over 500 related Aloe species in one of the world's largest succulent groups, have remained uncertain. We developed an explicit phylogenetic framework to explore links between the rich traditions of medicinal use and leaf succulence in aloes. RESULTS: The phylogenetic hypothesis clarifies the origins of Aloe vera to the Arabian Peninsula at the northernmost limits of the range for aloes. The genus Aloe originated in southern Africa ~16 million years ago and underwent two major radiations driven by different speciation processes, giving rise to the extraordinary diversity known today. Large, succulent leaves typical of medicinal aloes arose during the most recent diversification ~10 million years ago and are strongly correlated to the phylogeny and to the likelihood of a species being used for medicine. A significant, albeit weak, phylogenetic signal is evident in the medicinal uses of aloes, suggesting that the properties for which they are valued do not occur randomly across the branches of the phylogenetic tree. CONCLUSIONS: Phylogenetic investigation of plant use and leaf succulence among aloes has yielded new explanations for the extraordinary market dominance of Aloe vera. The industry preference for Aloe vera appears to be due to its proximity to important historic trade routes, and early introduction to trade and cultivation. Well-developed succulent leaf mesophyll tissue, an adaptive feature that likely contributed to the ecological success of the genus Aloe, is the main predictor for medicinal use among Aloe species, whereas evolutionary loss of succulence tends to be associated with losses of medicinal use. Phylogenetic analyses of plant use offer potential to understand patterns in the value of global plant diversity.

Literature, museums, and national identity; or, why are there so many writers' house museums in Britain?

Writers’ houses constitute the largest and oldest segment of historic house museums dedicated to famous persons in the United Kingdom. Litterateurs tend to ascribe ‘lit houses’ to the ineffable magic of readers’ connections to writers. By contrast, my analysis deploys the analytic of cultural politics to suggest that writers’ house museums can more fully be understood as assertions of national identity. The elision of language with national distinction is subliminal in everyday life, but can be brought to prominence by historicising the nations of the British Isles, and the practice of writing in English.
