The Maleny ‘Fire Event’: Rehearsals Toward Neo-liminality

Although the anthropological literature on ritual is extensive, little theoretical attention has been paid to recent attempts to (re)create rituals among mainstream groups in post-industrial, secularised societies. The authors address this issue by examiuning the annual Fire Event, which is constructed as a ritual climax to the Maleny Folk Festival in southern Queensland, Australia. Using the work of Victor Turner and John MacAloon as a point of departure, we argue that at best such celebrations constitute a neo-liminal framework within which participants can achieve a consensus of belief and action. By showing that some Fire Events have been more successful ‘rituals’ than others, we also highlight the factors which tend to impede participation and ‘con-subjectivity’ in such settings. In the process we identify some of the cultural divisions at Maleny, such as those between artists and ‘folk’, feral hippies and ‘hoons’, Aboriginals and Anglos, and begin to reflect on how these may relate to more general patterns of interaction in Australian society at large.     

THE PRIMARY ROOT EPIDERMIS OF PANICUM VIRGATUM L. I. ONTOGENY AND FINE STRUCTURE OF THE EPIDERMAL CYTOPLASMIC INCLUSIONS

The ontogeny of large, globular, epidermal cytoplasmic inclusions (ECI) in P. virgatum roots was studied at the ultrastructural level. These ECI were seen to originate in meristematic cells as small electron translucent vesicles. Subsequently, the ECI, which appeared to be temporary storage sites, were seen to enlarge and increase in density by accumulating masses of a granular matrix as well as some small vesicular inclusions. In the zone of elongation, as the epidermal cells matured, the ECI within each cell gradually fused and the contents were lost. The pattern of the ontogeny of the ECI in the growing epidermal cells was consistent with the presence of cells of different physiologies in the zone of cell elongation of these roots.     

Staining of sulphatides in metachromatic leukodystrophy with Alcian blue at high salt concentrations.

Alcian blue combines with purified sulphatide in 1.OM magnesium chloride. In tissue sections from patients with metachromatic leukodystrophy, sulphatide is stained by Alcian blue in 0.8 M magnesium chloride, and the staining can be abolished by prior treatment with chloroform and methanol. The simplicity of the technique, its specificity and ease of interpretation recommend Alcian blue staining at high salt concentrations as a routine method in the diagnosis of metachromatic leukodystrophy.     

Parasites, diseases and health status of sympatric populations of sambar deer and white-tailed deer in Florida

From December 1983 to December 1984 a study on parasites, diseases and health status was conducted on sympatric populations of sambar deer (Cervus unicolor) and white-tailed deer (Odocoileus virginianus) from St. Vincent Island, Franklin County, Florida. Ten sambar and six white-tailed deer were examined. White-tailed deer had antibodies to epizootic hemorrhagic disease virus and bluetongue virus. Serologic tests for antibodies to the etiologic agents of bovine virus diarrhea, infectious bovine rhinotracheitis, vesicular stomatitis, parainfluenza 3, brucellosis, and leptospirosis were negative in both species of deer. White-tailed deer harbored 19 species of parasites; all were typical of the parasite fauna of this species in coastal regions of the southeastern United States. Sambar deer harbored 13 species of parasites, which apparently were derived largely from white-tailed deer. The only exception was Dermacentor variabilis which occurs frequently on wild swine on the island. The general health status of sambar deer appeared to be better than that of white-tailed deer. This was hypothesized to result from the sambar deer's utilization of food resources unavailable or unacceptable to white-tailed deer and to the absence and/or lower frequency of certain pathogens in sambar deer.     

Critical considerations in the development of an assay for sulfidopeptide leukotrienes in plasma

A sensitive and specific assay has been developed for measurement of total sulfidopeptide leukotrienes (LT) in plasma. LTC4 and LTD4 in plasma are converted to LTE4 which is then extracted by C18 Sep-Pak binding and elution. Total LTE4 is resolved by reverse phase high performance liquid chromatography (RP-HPLC) and quantitated by radioimmunoassay (RIA). A [3H]LTE4 internal standard is added to the starting plasma sample to allow overall recovery to be calculated and to define the fractions from RP-HPLC to be assayed for LTE4-like immunoreactivity. The correlation between the measured increase in LTE4 concentration after addition of incremental amounts of LTC4 and LTE4 to plasma was 0.989 and 0.978, respectively, with slopes of 1.05 and 1.11. Addition of 51 pg/ml LTE4 to 5 ml plasma was detectable; the measured increase was 48 +/- 12 pg/ml (mean +/- SE, n = 7). The intra-assay coefficient of variation for 341 pg/ml of added LTC4 was 3.2% (n = 6). Sulfidopeptide leukotrienes could not be detected in blood samples taken from 12 normal volunteers in whom the theoretical detection limit, calculated from the sensitivity of the RIA, the overall recovery of LTE4, and the volume of plasma extracted, was 83 +/- 4 pg LTE4/ml plasma (0.19 +/- 0.01 pmol sulfidopeptide leukotriene/ml plasma; mean +/- SE).     

Free intermingling of mammalian beta-tubulin isotypes among functionally distinct microtubules

Mammalian cells express a spectrum of tubulin isotypes whose relationship to the diversity of microtubule function is unknown. To examine whether different isotypes are segregated into functionally distinct microtubules, we generated immune sera capable of discriminating among the various naturally occurring beta-tubulin isotypes. Cloned fusion proteins encoding each isotype were used first to tolerogenize animals against shared epitopes, and then as immunogens to elicit a specific response. In experiments using these sera, we show that there is neither complete nor partial segregation of beta-tubulin isotypes: both interphase cytoskeletal and mitotic spindle microtubules are mixed copolymers of all expressed beta-tubulin isotypes. Indeed, a highly divergent isotype normally expressed only in certain hematopoietic cells is also indiscriminately assembled into all microtubules both in their normal context and when transfected into HeLa cells.     

A mutant lymphoma cell line with a defectiveThy-1 glycoprotein gene

We characterized a mutant T -cell lymphoma line selected for the inability to express the Thy-1 glycoprotein. This cell line is a member of the D complementation class of Thy-1^– somatic cell mutants, and it lacks detectable cell-surface Thy-1.1 glycoprotein and detectable cytoplasmic Thy-1 mRNA. Southern blot analysis using a number of probes isolated from the clonedThy-1.2 gene demonstrated that, in the mutant, one copy of theThy-1 gene is absent from the genome and the other has undergone rearrangement. This rearrangement results from a deletion of the 5 portion of the gene removing the first two alternate exons and promoters and a portion of the second intron. The deletion breakpoint within the mutantThy-1 gene was localized to within 400 nucleotides by Southern blot analysis. The breakpoint is near two classes of mouse repetitive elements-a mouse B1-family repetitive element and a simple repetitive sequence-suggesting a mechanism of rearrangement leading to the mutation. Southern blot analysis demonstrated that two closely linked molecular markers on chromosome 9 are unaltered, demonstrating that the deletion in this mutant cell line is subchromosomal.
