Working in partnership through early support: distance learning text: working with parents in partnership (book chapter)

This is a chapter from the distance learning text for the 'Working in Partnership through Early Support' accredited training programme. "Our intention in this chapter... is to provide a theory of helping, known as the Family Partnership Model. It is based upon the notion that the most effective relationship between parent and helper is a partnership, as first discussed by Mittler, Cunningham and others in the 1970s. It is an explicit and relatively simple framework intended as a guide for all people working with children and their families. Having described the theory, we will look briefly at its implications for service development, training and professional support, the use of the Early Support materials in promoting partnership and the evidence for working in this way." - pp. 2-

Role of home visiting in improving parenting and health in families at risk of abuse and neglect : results of a multicentre randomised controlled trial and economic evaluation

Objectives – To evaluate the effectiveness and cost-effectiveness of an intensive home visiting programme in improving outcomes for vulnerable families. Design – Multicentre randomised controlled trial in which eligible women were allocated to receive home visiting (n=67) or standard services (n=64). Incremental cost analysis. Setting – 40 GP practices across two counties in the UK Participants – 131 vulnerable pregnant women. Intervention: Selected health visitors were trained in the Family Partnership Model to provide a weekly home visiting service from 6-months antenatally to 12 months postnatally. Main outcome measures – mother-child interaction, maternal psychological health attitudes and behaviour, infant functioning and development, and risk of neglect or abuse. Results – At 12-months differences favouring the home visited group were observed on an independent assessment of maternal sensitivity (p<0.04) and infant cooperativeness (p<0.02). No differences were identified on any other measures. There was a non-significant increase in the likelihood of intervention group infants being the subject of child protection proceedings, or being removed from the home, and one death in the control group. The mean incremental cost per infant of the home visiting intervention was £3,246 (bootstrapped 95% confidence interval for the difference: £1,645 - £4,803). Conclusion – This intervention may have the potential to improve parenting and increase the identification of infants at risk of abuse and neglect in vulnerable families. Further investigation is needed together with long term follow up to assess possible sleeper effects

Parent support advisor pilot : first interim report from the evaluation

The Parent Support Adviser (PSA) pilot is a government funded initiative to support 20 Local Authorities (LAs) to introduce PSAs into their workforce. The Department for Children, Schools and Families (DCSF) commissioned the Centre for Educational Development, Appraisal and Research (CEDAR) to evaluate the PSA pilot programme from September 2006 – August 2008. A government grant (£40 million) has been made available to fund employment of PSAs over this period. To date, 717 PSAs are in place, supporting parents in 1167 schools. This first Interim Report is based on semi-structured interviews with 97 PSAs, 85 line managers and 23 other professionals in 12 case study LAs during Phase 1 of the evaluation, which was carried out between April and June 2007. Phase 2 of the study will take place during the period October to December 2007; phase 3 will take place during March to June 2008. In addition to these interview-based studies with the 12 case study LAs, an analysis will be made of the data collected by all 20 LAs over the period of the pilot using a standard database devised by CEDAR. Data are being collected on the PSAs’ work with parents and, where this occurs, with children. Finally, a cost effectiveness study will be undertaken. The findings from these phases of the project will be reported in the final report

A Preliminary Study of CO2 Flux Measurements by Lidar

A mechanistic understanding of the global carbon cycle requires quantification of terrestrial ecosystem CO2 fluxes at regional scales. In this paper, we analyze the potential of a Doppler DIAL system to make flux measurements of atmospheric CO2 using the eddy-covariance and boundary layer budget methods and present results from a ground based experiment. The goal of this study is to put CO2 flux point measurements in a mesoscale context. In June 2007, a field experiment combining a 2-m Doppler Heterodyne Differential Absorption Lidar (HDIAL) and in-situ sensors of a 447-m tall tower (WLEF) took place in Wisconsin. The HDIAL measures simultaneously: 1) CO2 mixing ratio, 2) atmosphere structure via aerosol backscatter and 3) radial velocity. We demonstrate how to synthesize these data into regional flux estimates. Lidar-inferred fluxes are compared with eddy-covariance fluxes obtained in-situ at 396m AGL from the tower. In cases where the lidar was not yet able to measure the fluxes with acceptable precision, we discuss possible modifications to improve system performance

Dark Matter in the Galaxy Cluster CL J1226+3332 at Z=0.89

We present a weak-lensing analysis of the galaxy cluster CL J1226+3332 at z=0.89 using Hubble Space Telescope Advanced Camera for Surveys images. The cluster is the hottest (>10 keV), most X-ray luminous system at z>0.6 known to date. The relaxed X-ray morphology, as well as its high temperature, is unusual at such a high redshift. Our mass reconstruction shows that on a large scale the dark matter distribution is consistent with a relaxed system with no significant substructures. However, on a small scale the cluster core is resolved into two mass clumps highly correlated with the cluster galaxy distribution. The dominant mass clump lies close to the brightest cluster galaxy whereas the other less massive clump is located ~40" (~310 kpc) to the southwest. Although this secondary mass clump does not show an excess in the X-ray surface brightness, the gas temperature of the region is much higher (12~18 keV) than those of the rest. We propose a scenario in which the less massive system has already passed through the main cluster and the X-ray gas has been stripped during this passage. The elongation of the X-ray peak toward the southwestern mass clump is also supportive of this possibility. We measure significant tangential shears out to the field boundary (~1.5 Mpc), which are well described by an Navarro-Frenk-White profile with a concentration parameter of c200=2.7+-0.3 and a scale length of rs=78"+-19" (~600 kpc) with chi^2/d.o.f=1.11. Within the spherical volume r200=1.6 Mpc, the total mass of the cluster becomes M(r<r200)=(1.4+-0.2) x 10^15 solar mass. Our weak-lensing analysis confirms that CL1226+3332 is indeed the most massive cluster known to date at z>0.6.Comment: Accepted for publication in Ap

Turbulent CO2 Flux Measurements by Lidar: Length Scales, Results and Comparison with In-Situ Sensors

The vertical CO2 flux in the atmospheric boundary layer (ABL) is investigated with a Doppler differential absorption lidar (DIAL). The instrument was operated next to the WLEF instrumented tall tower in Park Falls, Wisconsin during three days and nights in June 2007. Profiles of turbulent CO2 mixing ratio and vertical velocity fluctuations are measured by in-situ sensors and Doppler DIAL. Time and space scales of turbulence are precisely defined in the ABL. The eddy-covariance method is applied to calculate turbulent CO2 flux both by lidar and in-situ sensors. We show preliminary mean lidar CO2 flux measurements in the ABL with a time and space resolution of 6 h and 1500 m respectively. The flux instrumental errors decrease linearly with the standard deviation of the CO2 data, as expected. Although turbulent fluctuations of CO2 are negligible with respect to the mean (0.1 %), we show that the eddy-covariance method can provide 2-h, 150-m range resolved CO2 flux estimates as long as the CO2 mixing ratio instrumental error is no greater than 10 ppm and the vertical velocity error is lower than the natural fluctuations over a time resolution of 10 s

Physical Properties of (2) Pallas

We acquired and analyzed adaptive-optics imaging observations of asteroid (2) Pallas from Keck II and the Very Large Telescope taken during four Pallas oppositions between 2003 and 2007, with spatial resolution spanning 32-88 km (image scales 13-20 km/pix). We improve our determination of the size, shape, and pole by a novel method that combines our AO data with 51 visual light-curves spanning 34 years of observations as well as occultation data. The shape model of Pallas derived here reproduces well both the projected shape of Pallas on the sky and light-curve behavior at all the epochs considered. We resolved the pole ambiguity and found the spin-vector coordinates to be within 5 deg. of [long, lat] = [30 deg., -16 deg.] in the ECJ2000.0 reference frame, indicating a high obliquity of ~84 deg., leading to high seasonal contrast. The best triaxial-ellipsoid fit returns radii of a=275 km, b= 258 km, and c= 238 km. From the mass of Pallas determined by gravitational perturbation on other minor bodies [(1.2 +/- 0.3) x 10-10 Solar Masses], we derive a density of 3.4 +/- 0.9 g.cm-3 significantly different from the density of C-type (1) Ceres of 2.2 +/- 0.1 g.cm-3. Considering the spectral similarities of Pallas and Ceres at visible and near-infrared wavelengths, this may point to fundamental differences in the interior composition or structure of these two bodies. We define a planetocentric longitude system for Pallas, following IAU guidelines. We also present the first albedo maps of Pallas covering ~80% of the surface in K-band. These maps reveal features with diameters in the 70-180 km range and an albedo contrast of about 6% wrt the mean surface albedo.Comment: 16 pages, 8 figures, 6 table
