Investigating the effectiveness and acceptability of oral health and related health behaviour interventions in adults with severe and multiple disadvantage:Protocol for a mixed-methods systematic review

Increasing numbers of people in England experience homelessness, substance use, and repeated offending (known as ‘severe and multiple disadvantage’; SMD). Populations experiencing SMD often have extremely poor oral health, which is closely inter-linked with high levels of substance use, smoking, and poor diet. This study aims to undertake an evidence synthesis to identify the effectiveness, resource requirements, and factors influencing the implementation and acceptability of oral health and related health behaviour interventions in adults experiencing SMD. Two systematic reviews will be conducted using mixed-methods. Review 1 will investigate the effectiveness and resource implications of oral health and related health behaviours (substance use, smoking, diet) interventions; Review 2 will investigate factors influencing the implementation of such interventions. The population includes adults (≥18 years) experiencing SMD. Standard review methods in terms of searches, screening, data extraction, and quality appraisal will be conducted. Narrative syntheses will be conducted. If feasible, a meta-analysis will be conducted for Review 1 and a thematic synthesis for Review 2. Evidence from the two reviews will then be synthesised together. Input from people with experience of SMD will be sought throughout to inform the reviews. An initial logic model will be iteratively refined during the review.</jats:p

Sur l'écran et les propriétés magnétiques d'une impureté en mouvement au sein d'un métal

The screening of a charged impurity which moves in a metal is studied by means of the phase-shift method ; we suppose that the self-consistent scattering potential is not changed by the motion. Next we analyse, in the Hartree-Fock approximation, the consequences of the motion on the possibility of existence of a magnetic moment localized on the impurity. The results show a tendency towards demagnetization of the impurity. The implications of these results for secondary ionic emission phenomena from targets such as A1M (where M is a transition element) is also mentioned.La charge d'écran d'une impureté chargée en mouvement dans un métal est étudiée à l'aide de la méthode des déphasages ; on suppose pour ce calcul que le potentiel self-consistent de diffusion reste inchangé par le mouvement de la particule. On analyse ensuite, dans l'approximation Hartree-Fock, l'effet du mouvement sur la possibilité d'existence de moment magnétique localisé sur l'impureté. Le résultat de cette étude fait apparaître une tendance à la démagnétisation de l'impureté. L'utilisation de ces résultats pour l'analyse des phénomènes d'émission ionique secondaire d'alliages de type A1M (où M est un élément de transition) est aussi évoquée

Effective practice with e-portfolios: How can the UK experience inform practice?

&lt;span&gt;This paper introduces the background to the JISC work within the e-portfolio domain in the UK and presents an overview of past and current activities and the drivers for these developments. This is followed by a review of JISC's approach to drawing out the learning and implications for e-portfolio practice from this extensive collection of work and its dissemination. The analysis of twenty one recently funded projects involving the use of e-portfolios in the UK is introduced. The findings suggest that e-portfolio implementation is particularly complex in part due to the number of stakeholders involved, the contexts in which e-portfolios can be applied and the number of purposes they can have. This research suggests that there are threshold concepts related to e-portfolio implementation and that developing an understanding of effective practice is not straightforward. However a means of supporting this understanding is suggested.&lt;/span&gt
