The idea of the record

This paper examines the idea of the sports record and its relation to our ideas of excellence, achievement and progress. It begins by recovering and reviewing the work of Richard Mandell, whose definition of the record emphasizes three central ideas: statistic, athletic and recognition. It then considers the work of Henning Eichberg, Allen Guttmann and Mandell, from the 1970s onwards, on the genesis of the modern sports record, explaining and developing their ideas via a distinction between descriptive and emulative records, and between different kinds of emulative records. This then permits an analysis of contemporary athletic and sports records. The idea of the significant record will also be advanced, offering the four-minute mile as an example, in an attempt to explicate our continuing fascination with such exceptional achievements. It then considers the contribution of recent discussions of sport technologies and the logic of quantifiable progress, and tries to put our obsession with records in perspective as but one way in which we respond to and evaluate sporting performance

Two Parameters for Three Dimensional Wetting Transitions

Critical effects at complete and critical wetting in three dimensions are studied using a coupled effective Hamiltonian H[s(y),\ell]. The model is constructed via a novel variational principle which ensures that the choice of collective coordinate s(y) near the wall is optimal. We highlight the importance of a new wetting parameter \Omega(T) which has a strong influence on critical properties and allows the status of long-standing Monte-Carlo simulation controversies to be re-examined.Comment: 4 pages RevTex, 2 encapsulated postscript figures, to appear in Europhys.

Alaska's System for Monitoring Compliance with the Juvenile Justice and Delinquency Prevention Act

Pursuant to Section 223(1)(15) of the Juvenile Justice and Delinquency Prevention Act of 1974 and 28 CFR Part 31.303(f), states are required to describe their plans and procedures for annually monitoring compliance with the Act. Alaska's monitoring plan was developed by the Justice Center of the University of Alaska Anchorage in 1988 under contract with the Alaska Division of Family and Youth Services (DFYS).Alaska Department of Health and Social Services, Division of Family and Youth ServicesI.

Reid on knowledge and justification in Physical Education

[FIRST PARAGRAPHS] To my knowledge, very little has been written on the educational justification of PE activities for the last decade. Since PE now does have a place on the National Curriculum, albeit arguably a minor one, the justification issue does seem to have been put on the back burner by the profession. In a recent and welcome addition to the literature, Reid revisits the debate, outlining two ‘conventional assumptions’ made by what he calls the ‘new orthodoxy’ in PE: 1. The ‘early Hirstian’ account3, which sees knowledge as propositional, and education as academic. When applied to PE, this suggests: 2. The distinction between practical performance and the ‘theory’ related to it - i.e. the propositional knowledge of Human Movement Science (HMS). The paper is a critique of these two assumptions, and a defence of the claim that PE ‘can indeed satisfy the knowledge requirements of education; but ... without making claims to academic significance’ (p95)

A silver ion water sterilization system

Small amounts of silver are incorporated in mixture of ion exchange resins, and water passing through this mixture is thus exposed to silver ion concentration. System is useful in self-contained water systems except city water systems where residual chlorine level is stipulated

JJDP Monitoring Data — 1988: JJDP Violations and Juvenile Detention Counts for Lockups, Jails, Adult Correctional Facilities and Juvenile Detention Centers

This data supplement to the 1988 Juvenile Justice and Delinquency Prevention Act Compliance Monitoring Report (Mar 1990) presents data on 1988 violations in Alaska of the Juvenile Justice and Delinquency Prevention Act (JJDPA), which mandates removal of status offenders and nonoffenders from secure detention and correctional facilities, sight and sound separation of juveniles and adults, and removal of juveniles from adult jails and lockups.Alaska Department of Health and Social Services, Division of Family and Youth ServicesJJDP Violations — 1988 / Offense Type by Duration of Detention — 1988 / All Facilities / Lockups / Jails / Correctional and Youth Facilitie

Construction and utilisation of a bidirectional reporter vector in the analysis of two nod-boxes in of Rhizobium loti : a thesis presented in partial fulfilment of the requirements for the Degree of Master of Science in Molecular Genetics at Massey University

The nod-box is a 47bp cis-acting regulatory region which has been conserved amongst every species of Rhizobium studied to date. In species such as R. meliloti and R. leguminosarum, the nod-box has been shown to promote constitutive activity towards the regulatory nodD gene, and flavonoid-inducible expression towards the divergently-transcribed nodABCIJ operon. This bidirectional regulation of the so-called common nod genes was not observed in R. loti. A previous analysis of this species had shown that its nod-box promoted inducible activity towards the truncated 'nodD' gene, as well as the nodACIJ operon. It was the unusual arrangement of these R. loti nod genes that had initially aroused interest in this bacteria. To further investigate the role of the nod-box in the regulation of the R. loti common nod genes, a bidirectional reporter vector (pSPV4) was constructed. This novel vector allowed the promoter activity of a cloned nod-box-containing fragment to be concurrently measured in either direction using the same culture of cells. To achieve this construct, the gusA gene from pRAJ260 was blunt-end ligated into pUC21. An in-frame ribosome binding site (rbs) was cloned upstream of the gusA coding sequence to facilitate transcriptional fusions. The rbs and gusA gene were later excised as a functional unit and blunt-end ligated into pMP220 alongside the B-galactosidase reporter gene but in the opposite orientation. Hence, both reporter genes could be divergently transcribed from a common regulatory region cloned into the multiple cloning site that separated the genes. The fragments of DNA that were eventually cloned into the bidirectional vector were generated through the polymerase chain reaction. Each DNA insert contained the nod-box bracketed by differing lengths of flanking region. Once these PCR-generated fragments had been sequenced in pUC118 and subcloned into pSPV4, the resulting constructs were transformed into R. loti cells by electroporation. As the electroporation of these cells had not previously been reported, the conditions for this procedure were established and optimised. The results obtained from the bidirectional reporter assays disagreed with those observed in the earlier assays by Teo (1990). Neither the nodACIJ nod-box of NZP2037 nor the nodB nod-box of NZP2213, showed bidirectional inducible expression. In fact, both nod-boxes showed constitutive expression in the 'nodD' direction and inducible expression in the opposite direction. This indicates that the control of the nod genes in R. loti is fundamentally the same as that seen in other fast-growing Rhizobium species. Three regulatory elements affecting the levels of nod gene expression have tentatively been identified outside the nod-box sequence, though the results indicating their presence may simply be·due to spacing differences between the nod-box and the reporter gene
