Failures of weak approximation in families

Given a family of varieties $X\to \mathbb{P}^n$ over a number field $k$, we determine conditions under which there is a Brauer-Manin obstruction to weak approximation for $100\%$ of the fibres which are everywhere locally soluble.Comment: 44 pages; there is a new application to integral points (Theorem 1.4) and Cor 1.5 recovers a well-known result concerning the Hasse principl

The professional socialisation of headteachers in England: Further findings from the National Headteacher Survey

This paper reports on a further investigation of data first accumulated through a national survey of headteachers conducted in 1999. The survey was conducted by means of a self-completion postal questionnaire with a stratified random sample of 10 per cent serving headteachers in England, totalling 2285 potential respondents in all. Completed returns were received from 1405 headteachers, an overall response rate of 62 per cent. Initial findings from the survey have subsequently been published as conference papers and journal articles (Male, 2000; Male and Hvizdak, 2000; Male and Male, 2001, Male 2001). The survey primarily sought to establish the respondents’ perceived state of readiness for the demands of the headteacher position in a number of job categories and competencies. A secondary aim was to allow respondents to attribute reasons to their state of readiness where they perceived it to be adequate or better. A third aim was to seek opinion from the respondents as to what provision and support would be beneficial to headteachers in their first two years in post. This further investigation has been commissioned by the National College for School Leadership and has been conducted by the original author, aided by two serving headteachers who have been appointed as research associates by the college during the period January to July of 2002

Analysis of surface tris (2,3-dibromopropyl) phosphate on chlorobutyl rubber SCAPE suits

Tris (2,30-dibromopropyl) phosphate was used to confer flame retardant properties on butyl rubber formulations used in protective clothing such as the self-contained atmospheric protective ensembles (SCAPE suits) worn at Kennedy Space Center in support of Apollo, Skylab, and Apollo-Soyuz missions since 1966. Because tris (2,3-dibromopropyl) phosphate is mutagenic, surface concentrations of the compound in SCAPE suits were investigated as were as potential methods of removing or isolating it. Analytical procedures for determining surface concentrations of the tris compound on non-porous materials are described. Soap-and-water washing is the most efficient method of removing the compound from fabricated SCAPE suits and unused material

Pastoral stock water workbook

The Pastoral Stock Water Workbook has been developed to assist you to estimate the costs of maintaining stock water and make informed decisions about managing existing and proposed water points. The first half of the Workbook provides background information on stock water points, their usage, advantages and disadvantages. Whilst the second part contains a series of stepby- step exercises that should be completed as you progress through the Workbook. The latter part of the Workbook aims to: • Show a worked example of the annual costs of maintaining water; • Provide tools to calculate water costs for your business; • Outline how to use this information to plan for future management; and • Assist you to make water point decisions that increases your business\u27 efficiency

Discourse and identity in a corpus of lesbian erotica

This article uses corpus linguistic methodologies to explore representations of lesbian desires and identities in a corpus of lesbian erotica from the 1980s and 1990s. We provide a critical examination of the ways in which “lesbian gender,” power, and desire are represented, (re-)produced, and enacted, often in ways that challenge hegemonic discourses of gender and sexuality. By examining word frequencies and collocations, we critically analyze some of the themes, processes, and patterns of representation in the texts. Although rooted in linguistics, we hope this article provides an accessible, interdisciplinary, and timely contribution toward developing understandings of discursive practices surrounding gender and sexuality
