Because of the recent rapid transition in Britain from an elite system of higher education (HE) to one in which a much larger propor tion of the population is intended to participate, many students—whose social backgrounds would previously have (to a large extent) precluded their involvement in HE—experience strangerhood within academia in a particularly acute form. This paper deals with the experiences of members of an one particular HE course, especially designed for students over 21 years old—such "mature" students are a group who has not been traditionally found in large numbers in British HE Such students describe dramatic changes in their sense of self and in their relationships with others—to the extent that their biographical continuity with their own past becomes problematical.The applicability of an idea touted by certain postmodern writers, "the new selfconsciousness," is considered. Attention is also paid to the practical implications of the findings.
Here we report the genome sequence of the lesion nematode, Pratylenchus coffeae, a significant pest of banana and other staple crops in tropical and sub-tropical regions worldwide. Initial analysis of the 19.67 Mb genome reveals 6712 protein encoding genes, the smallest number found in a metazoan, although sufficient to make a nematode. Significantly, no developmental or physiological pathways are obviously missing when compared to the model free-living nematode Caenorhabditis elegans, which possesses approximately 21 000 genes. The highly streamlined P. coffeae genome may reveal a remarkable functional plasticity in nematode genomes and may also indicate evolutionary routes to increased specialisation in other nematode genera. In addition, the P. coffeae genome may begin to reveal the core set of genes necessary to make a multicellular animal. Nematodes exhibit striking diversity in the niches they occupy, and the sequence of P. coffeae is a tool to begin to unravel the mechanisms that enable the extraordinary success of this phylum as both free-living and parasitic forms. Unlike the sedentary endoparasitic root-knot nematodes (Meloidogyne spp.), P. coffeae is a root-lesion nematode that does not establish a feeding site within the root. Because the P. coffeae nematode genome encodes fewer than half the number of genes found in the genomes of root-knot nematodes, comparative analysis to determine genes P. coffeae does not carry may help to define development of more sophisticated forms of nematode-plant interactions. The P. coffeae genome sequence may help to define timelines related to evolution of parasitism amongst nematodes. The genome of P. coffeae is a significant new tool to understand not only nematode evolution but animal biology in general.
