Amplified fragment length polymorphisms (AFLP) were used to study the inheritance of shell color in Argopecten irradians. Two scallops, one with orange and the other with white shells, were used as parents to produce four F-1 families by selfing and outcrossing. Eighty-eight progeny, 37 orange and 51 white, were randomly selected from one of the families for segregation and mapping analysis with AFLP and microsatellite markers. Twenty-five AFLP primer pairs were screened, yielding 1138 fragments, among which 148 (13.0%) were polymorphic in two parents and segregated in progeny. Six AFLP markers showed significant (P < 0.05) association with shell color. All six loci were mapped to one linkage group. One of the markers, F1f335, is completely linked to the gene for orange shell, which we designated as Orange1, without any recombination in the progeny we sampled. The marker was amplified in the orange parent and all orange progeny, but absent in the white parent and all the white progeny. The close linkage between F1f335 and Orange1 was validated using bulk segregation analysis in two natural populations, and all our data indicate that F1f335 is specific for the shell color gene, Orange1. The genomic mapping of a shell color gene in bay scallop improves our understanding of shell color inheritance and may contribute to the breeding of molluscs with desired shell colors.

We present a novel strategy that uses high-throughput methods of isolating and mapping C. elegans mutants susceptible to pathogen infection. We show that C. elegans mutants that exhibit an enhanced pathogen accumulation (epa) phenotype can be rapidly identified and isolated using a sorting system that allows automation of the analysis, sorting, and dispensing of C. elegans by measuring fluorescent bacteria inside the animals. Furthermore, we validate the use of Amplifluor as a new single nucleotide polymorphism (SNP) mapping technique in C. elegans. We show that a set of 9 SNPs allows the linkage of C. elegans mutants to a 5-8 megabase sub-chromosomal region.

This paper describes the role of the Royal Statistical Society in shaping statistical education within the UK and further afield. Until 2001 the Society had four agencies concerned with education at all levels. The work of these is discussed and recent new arrangements are outlined. The Society’s efforts to disseminate good practice through organising meetings and running a network of Associate Schools and College are explored in some detail.

This paper discusses the development of provision for the training of teachers in English further and technical education from 1945 to 1956. While these years saw little growth in this provision, they were formative in that the institutional and curricular patterns of teacher training for the diverse fields of technical and further education were developed at this time. The work of the three national centres in Bolton, London and Huddersfield, during the period of the Emergency Training Scheme (ETS) is summarised with particular reference to the influence of the Ministry of Education‟s conditions for ETS colleges and courses. With the ending of the ETS in 1951 the three centres were given permanent status as teacher training colleges which in turn brought them into association with their local universities as constituent colleges of their Area Training Organisations. The consequences of this transfer to the universities for the curriculum and assessment of technical teacher training and the 'policy dichotomy' of teacher training for secondary and technical education are examined.

This paper aims to create a picture of aspects of the working lives of some trainers of technical and further education teachers in a specialist teacher training college in Bolton, Lancashire, from the 1950s to the 1980's. There is little reference to technical teacher training in the literature on teacher training in the second half of the twentieth century. With this gap in mind, this paper sets out to record some memories and impressions of staff involved during these years. Using data from a series of semi-structured interviews, the discussion centres upon their perceptions of their work: of their students, the working environment, the curriculum and their relationships with the technical colleges for whom they were training teachers. The paper has three sections. It begins with a brief discussion of the issues arising from the choice of research methods. The second section contextualises the study and traces the history of Bolton Technical Teachers' Training College from its establishment through to its merger with the Institute of Technology in 1982. This is followed by the presentation and discussion of the interview data.

My underlying argument, in this paper, is that conceptualisations of power as a commodity, through which the 'disempowered-as-illiterate' subject moves towards becoming an 'empowered-as-literate' subject, forces constructs of identities into a powerful/powerless dichotomy which does not always do justice to diverse experiences. The claimed 'empowering' intentions of adult education programme and policy practice may, in reality, contribute to the dominance of restrictive disciplining and regulatory discursive practices. Moving away from emancipatory trajectories of adult education programmes that allege only liberation from domination, through 'literacy', can promise freedom points to another position of hope. Drawing on Foucauldian analysis, I explore sites of resistance as possibilities of transforming 'structures of understanding' at different levels. Officially validated and recognised transformations, in adult education programme as well as policy understandings, of the 'illiterate' subject may also hope to include choices in postures of autonomy (see Spivak 1996) made by programme participants in other 'fields' of socio-cultural practice linked to their material realities. Subsequently, 'empowerment' of the 'illiterate Indian village woman' cannot solely be imagined as a product of laws, policies and institutional discursive practices (see, for example, Gouws 2005; Rai 2003 on gender mainstreaming and Mosse 2005 on aid policy and practice). The 'illiterate Indian village woman' represented as a site of resistance, throughout this paper, displaces homogeneous representations of the 'illiterate' which situate her in the role of 'dependent' or 'victim', as failed attempts to rob her of her historical and political agency (Mohanty 1996). Through narrating other 'images' of refusal in my ethnographic vignettes, I hope to recognise different individuals' sense of agency, at all levels, as embedded in and evolving through forms of collective action that activate differences in order to develop possibilities and sustain hope for transforming historically rooted discursive practices of inequality. I provide ethnographic accounts of resisting 'literacy' programme participants, based in different villages in Bihar (Northern India), as accounts of resistance impacted on by notions of norms, translating and interpreting Others, networks and empowerment.

Approximately 85,000 part-time teaching staff working in further education (FE) and adult and community learning (ACL) are often seen as ‘a problem’. The intrinsic ‘part-timeness’ of these staff tends to marginalise them: they remain under-recognised and largely unsupported. Yet this picture is over-simplified. This article examines how part-time staff make creative use of professional autonomy and agency to mitigate problematic ‘casual employment’ conditions, reporting on results from Learning and Skills Development Agency-sponsored research (2002–2006) with 700 part-time staff in the learning and skills sector. The question of agency was reported as a key factor in part-time employment. Change is necessary for the professional agency of part-timers to be harnessed as the sector responds to ambitious sectoral ‘improvement’ agendas following the Foster Report and FE White Paper. Enhanced professionalisation for part-time staff needs greater recognition and inclusion in change agendas.
