'I would rather die': reasons given by 16-year-olds for not continuing their study of mathematics

Improving participation rates in specialist mathematics after the subject ceases to be compulsory at age 16 is part of government policy in England. This article provides independent and recent support for earlier findings concerning reasons for non- participation, based on free response and closed items in a questionnaire with a sample of over 1500 students in 17 schools, close to the moment of choice. The analysis supports findings that perceived difficulty and lack of confidence are important reasons for students not continuing with mathematics, and that perceived dislike and boredom, and lack of relevance, are also factors. There is a close relationship between reasons for non-participation and predicted grade, and a weaker relation to gender. An analysis of the effects of schools, demonstrates that enjoyment is the main factor differentiating schools with high and low participation indices. Building on discussion of these findings, ways of improving participation are briefly suggested

The relationship between tissue levels of flavone acetic acid (NSC 347512) and site dependent anti-tumour activity in murine colon tumours.

Flavone acetic acid (FAA) is extremely active against subcutaneous transplantable tumours in mice, but disappointingly there has been no demonstrable clinical activity. Previous studies have shown that lung tumour deposits are less responsive than the same cells implanted subcutaneously. The aim of this study is to examine the tissue disposition of FAA in an attempt to explain this site-dependent activity. The data show clearly that FAA clearance curves are influenced by the presence of MAC 15A tumours growing either subcutaneously or systemically. The decreased clearance of FAA from MAC 15A tumour bearing animals does not however explain the resistance of lung deposits. Neither can this be explained by differences in metabolism in these different sites. Cytotoxic metabolites have not been detected either in vitro or in vivo and their role in the mechanism of action of FAA is questionable

Geodynamic setting and origin of the Oman/UAE ophiolite

The ~500km-long mid-Cretaceous Semail nappe of the Sultanate of Oman and UAE (henceforth referred to as the Oman ophiolite) is the largest and best-preserved ophiolite complex known. It is of particular importance because it is generally believed to have an internal structure and composition closely comparable to that of crust formed at the present-day East Pacific Rise (EPR), making it our only known on-land analogue for ocean lithosphere formed at a fast spreading rate. On the basis of this assumption Oman has long played a pivotal role in guiding our conceptual understanding of fast-spreading ridge processes, as modern fast-spread ocean crust is largely inaccessible

What is the role of a specialist regional mesothelioma multidisciplinary team meeting?:A service evaluation of one tertiary referral centre in the UK

BACKGROUND: Multidisciplinary team meetings are standard care for cancer in the UK and Europe. Professional bodies recommend that mesothelioma cases should be discussed at specialist multidisciplinary team meetings. However, no evidence exists exploring the role of the specialist mesothelioma multidisciplinary team meeting. OBJECTIVES: To evaluate the clinical activity of 1 specialist mesothelioma multidisciplinary team meeting and to determine how often a definitive diagnosis was made, whether the core requirements of the meeting were met and whether there was any associated benefit or detriment. DESIGN AND SETTING: A service evaluation using routinely collected data from 1 specialist mesothelioma multidisciplinary team meeting in a tertiary referral hospital in the South-West of England. PARTICIPANTS: All cases discussed between 1/1/2014 and 31/12/2015. OUTCOME MEASURES: The primary outcome measure was whether a definitive diagnosis was made. Secondary outcomes included whether treatment advice was offered, information on clinical trials provided or further investigations suggested. Additional benefits of the multidisciplinary team meeting and time taken from referral to outcome were also collected. RESULTS: A definitive diagnosis was reached in 171 of 210 cases discussed (81%). Mesothelioma was diagnosed in 153/210 (73%). Treatment advice was provided for 127 of 171 diagnostic cases (74%) and further investigations suggested for all 35 non-diagnostic cases. 86/210 cases (41%) were invited to participate in a trial, of whom 43/86 (50%) subsequently enrolled. Additional benefits included the avoidance of postmortem examination if the coroner was satisfied with the multidisciplinary team decision. The overall process from referral to outcome dispatch was <2 weeks in 75% of cases. CONCLUSIONS: This specialist mesothelioma multidisciplinary team meeting was effective at making diagnoses and providing recommendations for further investigations or treatment. The core requirements of a specialist mesothelioma multidisciplinary team meeting were met. The process was timely, with most outcomes returned within 2 weeks of referral
