'Selling it as a holistic health provision and not just about condoms ?' Sexual health services in school settings: current models and their relationship with sex and relationships education policy and provision
In this article we discuss the findings from a recent study of UK policy and practice in relation to sexual health services for young people, based in - or closely linked with - schools. This study formed part of a larger project, completed in 2009, which also included a systematic review of international research. The findings discussed in this paper are based on analyses of interviews with 51 service managers and questionnaire returns from 205 school nurses. Four themes are discussed. First, we found three main service permutations, in a context of very diverse and uneven implementation. Second, we identified factors within the school context that shaped and often constrained service provision; some of these also have implications for sex and relationships education (SRE). Third, we found contrasting approaches to the relationship between SRE input and sexual health provision. Fourth, we identified some specific barriers that need to be addressed in order to develop 'young people friendly' services in the school context. The relative autonomy available to school head teachers and governors can represent an obstacle to service provision - and inter-professional collaboration - in a climate where, in many schools, there is still considerable ambivalence about discussing 'sex' openly. In conclusion, we identify areas worthy of further research and development, in order to address some obstacles to sexual health service and SRE provision in schools
What and how: doing good research with young people, digital intimacies, and relationships and sex education
© 2020, © 2020 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. As part of a project funded by the Wellcome Trust, we held a one-day symposium, bringing together researchers, practitioners, and policymakers, to discuss priorities for research on relationships and sex education (RSE) in a world where young people increasingly live, experience, and augment their relationships (whether sexual or not) within digital spaces. The introduction of statutory RSE in schools in England highlights the need to focus on improving understandings of young people and digital intimacies for its own sake, and to inform the development of learning resources. We call for more research that puts young people at its centre; foregrounds inclusivity; and allows a nuanced discussion of pleasures, harms, risks, and rewards, which can be used by those working with young people and those developing policy. Generating such research is likely to be facilitated by participation, collaboration, and communication with beneficiaries, between disciplines and across sectors. Taking such an approach, academic researchers, practitioners, and policymakers agree that we need a better understanding of RSE’s place in lifelong learning, which seeks to understand the needs of particular groups, is concerned with non-sexual relationships, and does not see digital intimacies as disconnected from offline everyday ‘reality’
BOREAS: Detecting Planetary Subsurface Water
Direct detection of water on planets beyond Earth has always been a primary goal for space exploration. Our “Boreas” project focuses on the integration of a student-designed S-Band Radar-based water detection system, which is capable of ice penetration. For improved reliability, the system is equipped with an automatic attitude determination and control subsystem. The Boreas project aims to design, test, and fabricate a small-scale radar capable of seeing through substantial layers of ice or other material covering a given body of water. Our orbiting radar will be able to orient itself to the planet during flyby and maintain nadir orientation as the sensing subsystem takes in subsurface data. This design was inspired by Jupiter’s moon Europa, which is known to harbor subsurface high-salinity oceans and further motivated by the recent exciting discovery of liquid water on Mars. The opportunities for application of the Boreas orbiter are numerous
Lesbian and bisexual women's human rights, sexual rights and sexual citizenship: negotiating sexual health in England.
Lesbian and bisexual women's sexual health is neglected in much Government policy and practice in England and Wales. This paper examines lesbian and bisexual women's negotiation of sexual health, drawing on findings from a small research project. Themes explored include invisibility and lack of information, influences on decision-making and sexual activities and experiences of services and barriers to sexual healthcare. Key issues of importance in this respect are homophobic and heterosexist social contexts. Drawing on understandings of lesbian, gay and bisexual human rights, sexual rights and sexual citizenship, it is argued that these are useful lenses through which to examine and address lesbian and bisexual women's sexual health and related inequalities
Limitations of focussing on homophobic, biphobic and transphobic ‘bullying’ to understand and address LGBT young people’s experiences within and beyond school
This paper presents new empirical data that highlight how a focus on ‘bullying’ is too limited and narrow when thinking about homophobia, biphobia and transphobia that young people may experience. The paper draws on two recent studies with young lesbian, gay, bisexual and trans participants, which each identified issues and experiences not readily captured within dominant bullying discourses and understandings. Findings are examined within three sections: beyond ‘bullying’, questioning inevitability, and (in)appropriate responses. In conclusion, I set out some implications and suggestions for the development of practice and future research concerning homophobia, biphobia and transphobia in youth settings
Experimental Constraints on Ocean Wave Erosion of Icebergs and Glaciers
Loss of ice from glaciers and ice sheets has been steadily increasing over recent decades due to rising oceanic and atmospheric temperatures. White (1980) developed a theoretical estimate for the erosion rate of icy surface by wave activity, which has since been used as the sole basis for calculating wave melting effects in ocean and ice sheet models. In this study, we conduct the first new experiments since White (1980) to test the established parameterization and extend it to a wider range of wave and water properties. A custom-built 1.2 meter long wave tank is used to simulate the behavior of ocean waves on ice shelves in a laboratory-scaled manner. White’s theory is tested for a wide range of conditions to within a reasonable margin of error (given the limitations of the tank and required assumptions). We further discuss how the results from this experiment can help to improve models of the high-latitude oceans for the benefit of predicting future climate, and assessing iceberg hazards to shipping
On One Parameter Functional Forms for Lorenz Curves
This paper shows that using a one-parameter functional form for the Lorenz curve is equivalent to ranking income distributions based on their Gini indices. Irrespective of the underlying data, the fitted Lorenz curves can never intersect. Circu mstances in which one-parameter Lorenz curves can safely be specified are identified and their policy relevance discussed.
Auditory and tactile gap discrimination by observers with normal and impaired hearing
Temporal processing ability for the senses of hearing and touch was examined through the measurement of gap-duration discrimination thresholds (GDDTs) employing the same low-frequency sinusoidal stimuli in both modalities. GDDTs were measured in three groups of observers (normal-hearing, hearing-impaired, and normal-hearing with simulated hearing loss) covering an age range of 21–69 yr. GDDTs for a baseline gap of 6 ms were measured for four different combinations of 100-ms leading and trailing markers (250–250, 250–400, 400–250, and 400–400 Hz). Auditory measurements were obtained for monaural presentation over headphones and tactile measurements were obtained using sinusoidal vibrations presented to the left middle finger. The auditory GDDTs of the hearing-impaired listeners, which were larger than those of the normal-hearing observers, were well-reproduced in the listeners with simulated loss. The magnitude of the GDDT was generally independent of modality and showed effects of age in both modalities. The use of different-frequency compared to same-frequency markers led to a greater deterioration in auditory GDDTs compared to tactile GDDTs and may reflect differences in bandwidth properties between the two sensory systems.National Institute on Deafness and Other Communication Disorders (U.S.) (Grant R01 DC000117
A dynamic model of the eye nystagmus response to high magnetic fields
It was recently shown that high magnetic fields evoke nystagmus in human subjects with functioning vestibular systems. The proposed mechanism involves interaction between ionic currents in the endolymph of the vestibular labyrinth and the static magnetic field. This results in a Lorentz force that causes endolymph flow to deflect the cupulae of the semi-circular canals to evoke a vestibular-ocular reflex (VOR). This should be analogous to stimulation by angular acceleration or caloric irrigation. We made measurements of nystagmus slow-phase velocities in healthy adults experiencing variable magnetic field profiles of up to 7 Tesla while supine on a bed that could be moved smoothly into the bore of an MRI machine. The horizontal slow-phase velocity data were reliably modelled by a linear transfer function incorporating a low-pass term and a high-pass adaptation term. The adaptation time constant was estimated at 39.3 s from long-exposure trials. When constrained to this value, the low-pass time constant was estimated at 13.6 3.6 s (to 95% confidence) from both short and long exposure trials. This confidence interval overlaps with values obtained previously using angular acceleration and caloric stimulation. Hence it is compatible with endolymph flow causing a cupular deflection and therefore supports the hypothesis that the Lorentz force is a likely transduction mechanism of the magnetic-field evoked VOR
