Trials and Tribulations - an RCT comparing manualized family therapy with Treatment as Usual and reflections on key issues that arose in the implementation
No full textSHIFT has been one of the largest RCTs in the field of systemic family therapy in the UK. The study took place over five years, including three major centres with fifteen Trusts and twenty-five family therapists who worked with a manualized treatment in CAMHS with adolescents who self-harmed. While the results are not available at the time of this publication, this paper will briefly describe the pre- existing factors which were helpful in developing a successful bid, clinical and managerial elements of ‘real world research’ of complex psychological processes and the construction of the manualized systemic family therapy. It also offers examples of some of the unanticipated events in the life of such a large trial
Family factors associated with adolescent self-harm: a narrative review
No full textThis narrative literature review focuses on family factors that might be amenable to intervention using family therapy (n=126). Domains of interest include parent/child interactions, inter-parental relationships, child characteristics, parental characteristics, wider system factors, treatment needs and moderators. The focus of family-orientated treatment with this population should focus on maximizing cohesion, attachment, adaptability, family support, parental warmth while reducing maltreatment, scapegoating and moderating parental control. Close working relationships with child protection services and schools represent additional opportunities. Practitioner points •Over and above any inherited risk, a range of family interactional factors are strongly associated with self-harming behaviours in young people •Therapy has the potential to make a positive difference by focusing on enhancing family cohesion and adaptability, whilst reducing discord and violence. Discussions that enhance perceived parental support and warmth may be particularly helpful •Therapists should attend to issues of perceived difference and potential victimization (bullying, gender orientation and identity, ethnic minority status) as these may play an important role in self-har
Radio and the Music Confessional
No full textIt is the hot, early summer of 2022 and I am sat in the garden of my house in south-east London, among thirsty flowers and wilting shrubs. Leaning back in a reclining chair, my feet propped up by another, I am listening to radio podcasts via my phone. A comfortable pair of headphones shuts out the surrounding urban noise, allowing me to lose myself in the radiophonic moment. I choose the next programme and press play. A familiar theme tune strikes up, overlaid with sounds of lapping waves and herring gulls, and I am ready to drift away for another forty minutes on an imaginary desert island, surrounded by the sea. The presenter, an invited guest, and me. Just the three of us
Numerical analysis of a 3-D printed porous trailing edge for broadband noise reduction
No full textLattice Boltzmann simulations were carried out to investigate the noise mitigation mechanisms of a 3-D printed porous trailing-edge insert, elucidating the link between noise reduction and material permeability. The porous insert is based on a unit cell resembling a lattice of diamond atoms. It replaces the last 20 % chord of a NACA 0018 at zero angle-of-attack. A partially blocked insert is considered by adding a solid partition between 84 % and 96 % of the aerofoil chord. The regular porous insert achieves a substantial noise reduction at low frequencies, although a slight noise increase is found at high frequencies. The partially blocked porous insert exhibits a lower noise reduction level, but the noise emission at mid-to-high frequency is slightly affected. The segment of the porous insert near the tip plays a dominant role in promoting noise mitigation, whereas the solid-porous junction contributes, in addition to the rough surface, towards the high-frequency excess noise. The current study demonstrates the existence of an entrance length associated with the porous material geometry, which is linked to the pressure release process that is responsible for promoting noise mitigation. This process is characterised by the aerodynamic interaction between pressure fluctuations across the porous medium, which is found at locations where the porous insert thickness is less than twice the entrance length. Present results also suggest that the noise attenuation level is related to both the chordwise extent of the porous insert and the streamwise turbulent length scale. The porous inserts also cause a slight drag increase compared to their solid counterpart. Wind Energ
Resonant Spaces: Electroacoustic Music and Ritual: A commentary on my recent music.
No full textThe following portfolio and commentary concerns music and performance works created between 2008 and 2012, and an exposition of the research, ideas, aesthetics and techniques that connect
these works. I will discuss in detail the role that archaeoacoustics has played in my composition of fixed and mixed media works and how it has influenced me aesthetically in my approach to live performance. I will also explain in each instance any actual data used from various research sources, and my metaphorical interpretation of various archaeological sites and acoustic phenomena. Similarly, I will discuss the concepts of shamanism, ritual and transcendence that have influenced me, and how these concepts are expressed in my instrumental works, fixed media and live performance pieces
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Direct P-Wave Seismic Noise Interferometry for Groundwater Monitoring: A Modelling Study
No full textIn this study, we monitor the depth variation of an unconfined aquifer by applying seismic noise interferometry to synthetic data modelled with a 2D finite-difference software. We consider two models with the same subsurface geological structure, but with different water table levels representing two monitoring periods. The receivers are placed at the topographic surface and collect the seismic signals generated by a source located at the bottom of the aquifer to simulate a pumping system. First, cross-correlation of seismic traces with a reference one is used to produce interferograms (i.e., virtual surveys) for both the tested models. Then, direct P-wave arrivals identified in the two interferograms are compared through the stretching technique in order to estimate the relative velocity changes (dv/v). Finally, the estimated dv/v values are related to theoretical ones obtained using a reference subsurface model to produce the water level depth in the considered monitoring period.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Geophysics and Petrophysic
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
