Migration, Ethnicity and Privilege

Representation assumes that those who govern have knowledge of those for whom they govern. It is easy to presume knowledge of the “other”, but as we know this can be based in prejudice, cultural difference, or simply misinformation or simplification. Usually our explorations of this process have focused on populations identified as disadvantaged, disempowered or somehow “non-privileged”. However, the research process outlined here has revealed previously unexplored diversity within a population commonly described as privileged suggesting that good governance requires alertness to presuming to know both the unprivileged and the privileged. The research approach outlined in this paper has used a blend of historical reappraisal and qualitative techniques focusing on a population who have been conceptualized as doubly privileged. This population focus is that of older British; post World War II male migrants in South Australia. These people have been conceptualized as privileged because they are male, and they were part of the preferred ethnic group that Australian politicians and policy makers favoured post WW2. However, review of the historical data and qualitative interviews with some of these men show that the accepted narrative of a homogenous pre-WW2 British origin population is over simplistic. The historical research suggests that the presumption that post WW2 British migrant men were coming into an homogenous, privileging environment in migrating to SA is both ahistorical and crude. Furthermore the belief that post WW2 British migrant men were ethnically homogenous is undermined by the qualitative research, that reveals that their presumed homogeneity is much more fluid and nuanced than dominant conceptualisations have allowed. The impact of core ethnicities that continue to exist and compete in Britain, the social class focus and economic commodification of migrants in the machinations of powerful players in the state of South Australia all confound homogenizing, simplistic knowing of British migrant men in this state. Generically these findings caution social researchers with regard to presuming to know so called “privileged” populations as well as presumed non-privileged groups.     

Dynamic landforms and plant communities in a pluvial lake basin

Mapping units were developed based on landform, soils, and plant communities for the 40,000 ha of salt desert vegetation located below the maximum level of pluvial Lake Gilbert in Grass Valley, Nevada. Lake plain, beach, and bar features of the pluvial lake provide the dominant landforms. Fine textured lake sediments have produced salt- and Na-affected soils. The distribution and structure of plant communities are related to depth of the groundwater table, fluctuations in this depth, and the salt content of the groundwater. Wind and water erosion combine to continually evolve new environments for colonization by plants in this ecosystem.       

Plant age/size distributions in black sagebrush ( Artemisia nova ): effects on community structure

The demography of black sagebrush ( Artemisia nova Nelson) was investigated in the Buckskin Mountains of western Nevada to determine patterns of stand renewal in sagebrush communities currently free from wildfires. Biomass sampling was conducted to develop growth classes that reflected apparent age of the shrubs. The density of black sagebrush plants was twice that of basin big sagebrush ( A. tridentata ssp. tridentata Nutt.) in adjacent communities on contrasting soils (2.2 versus 1.1 plants per m 2 ). Black sagebrush accumulated only 75% as much woody biomass as big sagebrush. Regression equations were developed and tested for predicting total woody biomass, current annual growth (CAG), and leaf weight of black sagebrush plants. Apparent age classes were developed both for the black sagebrush plants and the sub-canopy mounds on which they grew. Discriminant analysis was used to test this classification system. Plant succession, apparently controlled by nitrate content of the surface soil, appeared to eliminate the successful establishment of black sagebrush seedlings on the mounds. After the shrubs die, the mounds eventually deflate. We propose that mounds reform around shrub seedlings, but because seedling establishment is so rare in these communities, this could not be verified.     

Preparation of isolated cells from rat heart

Summary Suspensions of isolated cells from rat heart were prepared and the data for viability and yield are given. Glucose uptake by the cells was mediated by a carrier system.The technical assistance of Mr.E. T. Potter, Mr.K. D. Patel and Mr.M. Griffin is gratefully acknowledged.     

Effect of the juvenoid methoprene on the hemolymph composition of the cabbage maggotDelia radicum (Diptera: Anthomyiidae)

Summary Treatment of post-feeding larvae of the cabbage maggotDelia radicum with methoprene did not affect the capacity of the insect to pupate, but suppressed eclosion to the adult stage. The concentration of hemolymph trehalose was significantly decreased by methoprene treatment, although hemolymph protein and amino nitrogen levels were unaffected.19 December 1986The authors are grateful to D. C. Read of the Research Centre, Agriculture Canada, Charlottetown, P.E.I., Canada for supplying eggs ofD. radicum for the stock colony. TheD. radicum colony was maintained at the Agriculture Canada Research Station, St. John's West, Newfoundland, Canada. The sample of methoprene was donated by Zoecon Corp., Palo Alto, California, U.S.A. This research was supported by a grant from the Natural Sciences and Engineering Research Council of Canada (Operating grant A6679).     

Transposon-dependent mutant phenotypes at the Notch locus of Drosophila

Many mutations at complex genetic loci in the fruitfly Drosophila melanogaster are associated with insertions of transposable elements. At the Notch locus, members of one class of insertion-associated mutations, termed glossy-like, produce a recessive viable, smooth-eye phenotype with mottled pigmentation. Members of a second class, facet, produce a recessive viable, rough-eye phenotype with homogeneous pigmentation. Both classes of mutations fail to complement Notch lethal mutations, so they behave as Notch alleles. Here we report that each glossy-like mutation is associated with an insertion of the same transposable element (flea). Each flea insertion occurs in the same orientation, but at different locations within intervening sequences of the Notch locus. In contrast, each facet mutation is associated with insertion of a unique, non-flea, transposable element. Insertions producing a facet phenotype and insertions causing a glossy-like phenotype can break Notch intervening sequences at precisely the same location. This suggests that the type of insertion element rather than its position within an affected gene is the primary determinant of the phenotype observed.
