Counting Is Not Enough: Investing in Qualitative Case Reviews for Practice Improvement in Child Welfare

Outlines the value of quality case service reviews in child welfare systems, requirements for building and sustaining a robust process and adapting it under limited state budgets, and recommendations for jurisdictions, initiators, and national leadership

An Independent Evaluation of the Strategic Legal Fund for Vulnerable Young Migrants

The Strategic Legal Fund for Vulnerable Young Migrants1 (SLF) was set up by the Diana Princess of Wales Memorial Fund (DPOWMF) in 2011. When the Diana Fund closed down in late 2012, Trust for London agreed to take over the hosting of the SLF and provided additional funding with Esmée Fairbairn Foundation for a second phase (December 2012 to March 2014 initially, though this has now been extended).In 2012 an interim evaluation of the SLF concluded that it was achieving results, and suggested some changes of focus and operation for the future. One year on, the purpose of this further evaluation is: a. to identify the full range of outcomes, benefits and changes to which the SLF project has contributed in order to understand the value of what has been funded to date. b. to help Trust for London, Esmée Fairbairn Foundation and other potential funders discuss and decide if and how they want to take forward the funding of strategic legal work on migration issues in the current climate. c. to take stock of the model being used to identify, assess, support and review SLF grants and learn lessons about this which can: i) help improve current ways of working; ii) enable decisions about how such a fund should be administered in the future. d. to stimulate discussions about the potential use of such a model in funding strategic legal work in other areas of law

Formant dynamics and durations of um improve the performance of automatic speaker recognition systems

We assess the potential improvement in the performance of MFCC-based automatic speaker recognition (ASR) systems with the inclusion of linguistic-phonetic information. Likelihood ratios were computed using MFCCs and the formant trajectories and durations of the hesitation marker um, extracted from recordings of male standard southern British English speakers. Testing was run over 20 replications using randomised sets of speakers. System validity (EER and Cllr) was found to improve with the inclusion of um relative to the baseline ASR across all 20 replications. These results offer support for the growing integration of automatic and linguistic-phonetic methods in forensic voice comparison

Coalition Against the Deportation of Irish Children: Evaluation of CADIC Achievements 2006-2007 (Final Report)

CADIC is widely considered to have been a very successful coalition by its members, funders and external parties. It mounted a high quality campaign that influenced government policy and provided effective support to a large number of vulnerable people. Its experience of coalition working highlights the following critical success factors that other NGOs entering a collaborative working model should consider carefully

The use of Dynamic Assessment by educational psychologists in the UK

Training in Dynamic Assessment (DA) was rarely available in the UK until 1994. This is the first study to explore the outcomes of its availability in terms of the practice of DA and perceptions about it among educational psychologists (EPs). One hundred and nineteen EPs who had taken positive steps to inform themselves about DA by undertaking some degree of training or by joining a DA interest group, were surveyed to explore the extent of their initial training in DA, subsequent use of it and issues of implementation. Overall, the 88 responses (74%) received suggest, among those surveyed, widespread awareness of DA as a model of cognitive assessment and positive attitudes to it, coupled with a low level of implementation. The low level of use was frequently attributed to insufficient training in DA, to lack of time due to other assessment priorities, often set by the Local Education Authority, and to lack of the ongoing expert support felt to be necessary to maintain use of a demanding form of assessment. The authors take the position that the EP's repertoire would be enriched by improved knowledge of and training in DA. The research raises important issues for cognitive assessment, and also raises the broader question whether there is a need for a more proactive involvement of educators in enhancing the cognitive functioning of children

Occurrence and associative value of non-identifiable fingermarks

Fingermarks that have insufficient characteristics for identification often have discernible characteristics that could form the basis for lesser degrees of correspondence or probability of occurrence within a population. Currently, those latent prints that experts judge to be insufficient for identification are not used as associative evidence. How often do such prints occur and what is their potential value for association? The answers are important. We could be routinely setting aside a very important source of associative evidence, with high potential impact, in many cases; or such prints might be of very low utility, adding very little, or only very rarely contributing to cases in a meaningful way. The first step is to better understand the occurrence and range of associative value of these fingermarks. The project goal was to explore and test a theory that in large numbers of cases fingermarks of no value for identification purposes occur and are readily available, though not used, and yet have associative value that could provide useful information. Latent fingermarks were collected from nine state and local jurisdictions. Fingermarks included were those (1) collected in the course of investigations using existing jurisdictional procedures, (2) originally assessed by the laboratory as of no value for identification (NVID), (3) re-assessed by expert review as NVID, but with least three clear and reliable minutiae in relationship to one another, and (4) determined to show at least three auto-encoded minutiae. An expected associative value (ESLR) for each mark was measured, without reference to a putative source, based on modeling within-variability and between-variability of AFIS scores. This method incorporated (1) latest generation feature extraction, (2) a (minutiae-only) matcher, (3) a validated distortion model, and (4) NIST SD27 database calibration. Observed associative value distributions were determined for violent crimes, property crimes, and for existing objective measurements of latent print quality. 750 Non Identifiable Fingermarks (NIFMs) showed values of Log10 ESLR ranging from 1.05 to 10.88, with a mean value of 5.56 (s.d. 2.29), corresponding to an ESLR of approximately 380,000. It is clear that there are large numbers of cases where NIFMs occur that have high potential associative value as indicated by the ESLR. These NIFMs are readily available, but not used, yet have associative value that could provide useful information. These findings lead to the follow-on questions, “How useful would NIFM evidence be in actual practice?” and, “What developments or improvements are needed to maximize this contribution?
