Enhancing Interns’ Aspirations towards the Labour Market through Skill-Acquisition: The Second Chance Schools Experience

Second Change School programmes are active in a number of European countries. These schools offer vulnerable young adults an alternative opportunity to enhance their employability skills by alternating education with work experience. People enrolling in these programmes disengaged from schools at an early age. They already experienced or are at-risk to enter into unemployment. This paper examines the impact of the Second Chance Schools on their participants’ aspirations towards the labour market through skill-acquisition. We are able to identify the perception of Second Chance Schools’ interns regarding entry to the professional life. A third of them, for example, consider their attitude or their surroundings as a barrier preventing them from getting a job. However, our results emphasise the role of the interns’ coach in improving their aspirations towards the labour market. We also show that when compared to male interns, female interns have a stronger (positive) perception of the school as a place where they can gain skills.

A Survey of Active Learning Algorithms for Supervised Remote Sensing Image Classification

Defining an efficient training set is one of the most delicate phases for the success of remote sensing image classification routines. The complexity of the problem, the limited temporal and financial resources, as well as the high intraclass variance can make an algorithm fail if it is trained with a suboptimal dataset. Active learning aims at building efficient training sets by iteratively improving the model performance through sampling. A user-defined heuristic ranks the unlabeled pixels according to a function of the uncertainty of their class membership and then the user is asked to provide labels for the most uncertain pixels. This paper reviews and tests the main families of active learning algorithms: committee, large margin, and posterior probability-based. For each of them, the most recent advances in the remote sensing community are discussed and some heuristics are detailed and tested. Several challenging remote sensing scenarios are considered, including very high spatial resolution and hyperspectral image classification. Finally, guidelines for choosing the good architecture are provided for new and/or unexperienced user.

Structured output SVM for remote sensing image classification

In the recent years, kernel methods have revealed very powerful tools in many application domains in general and in remote sensing image classification in particular. The special characteristics of remote sensing images (high dimension, few labeled samples and different noise sources) are efficiently dealt with kernel machines. In this paper, we propose the use of structured output learning to improve remote sensing image classification based on kernels. Structured output learning is concerned with the design of machine learning algorithms that not only implement input-output mapping, but also take into account the relations between output labels, thus generalizing unstructured kernel methods. We analyze the framework and introduce it to the remote sensing community. Output similarity is here encoded into SVM classifiers by modifying the model loss function and the kernel function either independently or jointly. Experiments on a very high resolution (VHR) image classification problem shows promising results and opens a wide field of research with structured output kernel methods.

Active mitral ring for post-surgical remote correction of residual mitral regurgitation on the beating heart.

OBJECTIVES: Residual mitral regurgitation after valve repair worsens patients' clinical outcome. Postimplant adjustable mitral rings potentially address this issue, allowing the reshaping of the annulus on the beating heart under echocardiography control. We developed an original mitral ring allowing valve geometry remodelling after the implantation and designed an animal study to assess device effectiveness in correcting residual mitral regurgitation. METHODS: The device consists of two concentric rings: one internal and flexible, sutured to the mitral annulus and a second external and rigid. A third conic element slides between the two rings, modifying the shape of the flexible ring. This sliding element is remotely activated with a rotating tool. Animal model: in adult swine, under cardio pulmonary bypass and cardiac arrest, we shortened the primary chordae of P2 segment to reproduce Type III regurgitation and implanted the active ring. We used intracardiac ultrasound to assess mitral regurgitation and the efficacy of the active ring to correct it. RESULTS: Severe mitral regurgitation (3+ and 4+) was induced in eight animals, 54 ± 6 kg in weight. Vena contracta width decreased from 0.8 ± 0.2 to 0.1 cm; proximal isovelocity surface area radius decreased from 0.8 ± 0.2 to 0.1 cm and effective regurgitant orifice area decreased from 0.50 ± 0.1 to 0.1 ± 0.1 cm(2). Six animals had a reversal of systolic pulmonary flow that normalized following the activation of the device. All corrections were reversible. CONCLUSIONS: Postimplant adjustable mitral ring corrects severe mitral regurgitation through the reversible modification of the annulus geometry on the beating heart. It addresses the frequent and morbid issue of recurrent mitral valve regurgitation.

Epidemiological Aspects of Head Lice in Children Attending Day Care Centres, Urban and Rural Schools in Uberlândia, Central Brazil

From November 1996 to March 2000, a total of 884 children between 0 and 15 years, from 11 institutions including day care centres, public urban and public rural schools in Uberlândia, State of Minas Gerais, central Brazil, were examined for head louse infestation. Children's sex, race, age and some hairs characteristics were shown to be associated to parasite infestation. A prevalence rate of 35% was found and the highest rates were observed in black, female children, with long, dark, wavy hairs. Hairs density and thickness did not seem to influence significantly the distribution of this pediculosis in Uberlândia's schoolchildren. Differences observed between the prevalence rates of head lice in children from the urban institutions suggest there is a greater epidemiological heterogeneity in this group when compared to the rural schoolchildren.

European Schools Survey Project on Alcohol and other drugs (ESPAD)

ESPAD is a collaborative effort of independent research teams in about forty European countries and the largest cross-national research project on adolescent substance use in the world. Data are collected every fourth year with 1995 as the starting point. The fourth data collection was carried out in 35 countries during the spring of 2007 and the results were published March 26, 2009 The overall purpose of the ESPAD project is to study adolescent substance use in Europe from a comparative and longitudinal perspective. The basic goal is to collect comparable data on the use of alcohol, tobacco and other drugs among students throughout European countries. Data should be collected in cooperation between countries using a strictly standardised methodology, in order to offer as comparable results as possible. In the long run the most important aim is to monitor the of trends of the adolescent substance use in European countries and to compare trends between countries. This includes the mapping of differences and the monitoring of trends for policy purposes as well as the scientific study of the context, predictors and consequences of adolescent substance use. In relation to the EU action plan on drugs and the WHO Europe declaration about young people and alcohol, ESPAD-data can provide information for the evaluation of these charters. It is intended to repeat the surveys every fourth year. All European countries are welcome to join the ESPAD study, in the effort of making the coverage across Europe as complete as possible.

School food: top marks - A summary report on food in schools research in Northern Ireland

Thisreport highlightsthe barriers that schools in Northern Ireland have experienced in implementing nutritional standards. In particular, it identifies the potential adverse impact that external sources of food may have on pupils’ healthy eating practices within the school setting. It also illustrates how the accessibility of food and drinks contradicting the standards, within the school, may limit the success of the standards. This report further emphasises how practical constraints within the school meals system, such as queues, can negatively influence pupils’ uptake of healthy foods. The report outlinesa number of recommendations to aid the implementation of the School food: top marks programme.

What is a serving size: A guide for pre-schools

This guide offers practical help to all those providing food for pre-school age children. It is a pictorial manual giving real life serving sizes to guide care-givers, parents and guardians on suitable size servings. This booklet also provides sound advice on family-style eating habits, the introduction of new foods and the environment which nurtures healthy eating habits for life. Establishing good lifestyle habits, including positive attitudes and behaviours around food is one of the key cornerstones to shaping future health. This starts during the pre-school years when children grow rapidly and begin to learn about the environment around them. Providing an environment that supports healthy eating both at home and at school is important. It is well recognised that gauging portion sizes for young children can besomewhat difficult; they need to be adequate without being excessive.

Building Children and Young People's Resilience in Schools

Evidence Review 2 - Building children and young people's resilience in schools Briefing 2 - Building children and young people's resilience in schools This pair of documents, commissioned by Public Health England, and written by the UCL Institute of Health Equity, address the role of schools in building children and young people’s resilience and capabilities. They provide a summary of evidence about the effect of resilience on health, the unequal distribution of resilience and its contribution to levels of health inequalities. The review outlines the potential actions that can be taken in schools in order to build resilience for all children and young people and reduce inequalities in resilience. Throughout, a social determinants approach to resilience is taken. Children and young people’s individual characteristics are seen as shaped by, and related to, inequities in power, money and resources, and the conditions in which they are born, grow, live, and in which they will work and age. Family and community resilience are highly significant and similarly shaped by wider social and economic factors. The full evidence review and a shorter summary briefing are available to download above. This document is part of a series. An overview document which provides an introduction to this and other documents in the series, and links to the other topic areas, is available on the ‘Local Action on health inequalities’ project page. A video of Michael Marmot introducing the work is also available on our videos page.

A Study of the Epidemiology of AIDS in Ireland and an Evaluation of an AIDS Education Programme in Second-level Schools

Second-level school students have been identified by the Minister for health as a priority group for education on AIDS. An education programme was accordingly initiated in 1988 in Community Care Area 1 in South county Dublin. This report evaluates this education intervention by means of pre- and post- intervention questionnaires. The questionnaire examined knowledge and attitudes of students relevant to AIDS. The results showed that the level of knowledge of students living in this area was high prior to intervention. The education programme succeeded in improving some aspects of knowledge and also influenced some attitudes of the students. A study of the epidemiology of Aids in Ireland reveals that the epidemic is at a relatively early stage with a consequent rapid doubling time of 9-10 months. In comparison with most developed countries Ireland has a high proportion of AIDS cases occurring among intravenous drug abusers and directly related to this a high number of HIV infected children. Examination of the literature reveals that behaviour change has occurred most noticeably among the homosexual/bisexual risk group. There is some evidence that the comprehensive programmes can achieve change in the behaviour of intravenous drug abusers. There are very few reports linking behaviour change among adolescents and young adults to education programmes. Much of the available literature relates to changes in knowledge and attitudes. International recommendations on the nature of the ideal health education intervention on AIDS are reviewed. The importance of a comprehensive health education programme which incorporates AIDS education and which commences early in youth is noted. The role of the community physician in relation to education programmes and other aspects of monitoring and management of the AIDS epidemic is discussed.This resource was contributed by The National Documentation Centre on Drug Use.
