Assessing the sensitivity of blue mussel beds to pressures associated with human activities.

The Joint Nature Conservation Committee (JNCC) commissioned this project to generate an improved understanding of the sensitivities of blue mussel (Mytilus edulis) beds, found in UK waters, to pressures associated with human activities in the marine environment. The work will provide an evidence base that will facilitate and support management advice for Marine Protected Areas, development of UK marine monitoring and assessment, and conservation advice to offshore marine industries. Blue mussel beds are identified as a Habitat of Principle Importance (HPI) under the Natural Environment and Rural Communities (NERC) Act 2006, as a Priority Marine Feature (PMF) under the Marine (Scotland) Act 2010, and included on the OSPAR (Annex V) list of threatened and declining species and habitats. The purpose of this project was to produce sensitivity assessments for the blue mussel biotopes included within the HPI, PMF and OSPAR habitat definitions, and clearly document the supporting evidence behind the assessments and any differences between them. A total of 20 pressures falling in five categories - biological, hydrological, physical damage, physical loss, and pollution and other chemical changes - were assessed in this report. The review examined seven blue mussel bed biotopes found on littoral sediment and sublittoral rock and sediment. The assessments were based on the sensitivity of M. edulis rather than associated species, as M. edulis was considered the most important characteristic species in blue mussel beds. To develop each sensitivity assessment, the resistance and resilience of the key elements are assessed against the pressure benchmark using the available evidence gathered in this review. The benchmarks were designed to provide a ‘standard’ level of pressure against which to assess sensitivity. Blue mussel beds were highly sensitive to a few human activities: • introduction or spread of non-indigenous species (NIS); • habitat structure changes - removal of substratum (extraction); and • physical loss (to land or freshwater habitat). Physical loss of habitat and removal of substratum are particularly damaging pressures, while the sensitivity of blue mussel beds to non-indigenous species depended on the species assessed. Crepidula fornicata and Crassostrea gigas both had the potential to outcompete and replace mussel beds, so resulted in a high sensitivity assessment. Mytilus spp. populations are considered to have a strong ability to recover from environmental disturbance. A good annual recruitment may allow a bed to recovery rapidly, though this cannot always be expected due to the sporadic nature of M. edulis recruitment. Therefore, blue mussel beds were considered to have a 'Medium' resilience (recovery within 2-10 years). As a result, even where the removal or loss of proportion of a mussel bed was expected due to a pressure, a sensitivity of 'Medium' was reported. Hence, most of the sensitivities reported were 'Medium'. It was noted, however, that the recovery rates of blue mussel beds were reported to be anywhere between two years to several decades. In addition, M. edulis is considered very tolerant of a range of physical and chemical conditions. As a result, blue mussel beds were considered to be 'Not sensitive' to changes in temperature, salinity, de-oxygenation, nutrient and organic enrichment, and substratum type, at the benchmark level of pressure. The report found that no distinct differences in overall sensitivity exist between the HPI, PMF and OSPAR definitions. Individual biotopes do however have different sensitivities to pressures, and the OSPAR definition only includes blue mussel beds on sediment. These differences were determined by the position of the habitat on the shore and the sediment type. For example, the infralittoral rock biotope (A3.361) was unlikely to be exposed to pressures that affect sediments. However in the case of increased water flow, mixed sediment biotopes were considered more stable and ‘Not sensitive’ (at the benchmark level) while the remaining biotopes were likely to be affected.

Using a clearly documented, evidence-based approach to create sensitivity assessments allows the assessment basis and any subsequent decision making or management plans to be readily communicated, transparent and justifiable. The assessments can be replicated and updated where new evidence becomes available ensuring the longevity of the sensitivity assessment tool. For every pressure where sensitivity was previously assessed as a range of scores in MB0102, the assessments made by the evidence review have supported one of the MB0102 assessments. The evidence review has reduced the uncertainty around assessments previously undertaken in the MB0102 project (Tillin et al., 2010) by assigning a single sensitivity score to the pressures as opposed to a range. Finally, as blue mussel bed habitats also contribute to ecosystem function and the delivery of ecosystem services, understanding the sensitivity of these biotopes may also support assessment and management in regard to these. Whatever objective measures are applied to data to assess sensitivity, the final sensitivity assessment is indicative. The evidence, the benchmarks, the confidence in the assessments and the limitations of the process, require a sense-check by experienced marine ecologists before the outcome is used in management decisions.

Monitorización de la temperatura del pie como herramienta en la neuropatía diabética

Objteivo: Valorar si existe relación entre el aumento de temperatura en el pie y la neuropatía diabética periférica. Métodos: La muestra fueron 27 pacientes diabéticos a que se le realizó una exploración neurológica y vascular, además, haciendo uso de un termómetro infrarrojo medimos la temperatura en distintos puntos anatómicos de la planta del pie. Resultados: La temperatura es mayor los pacientes con neuropatía con una diferencia de 2,24ºC (p=0,454) en el pie derecho y 0,86ºC (p=0,589) en el pie izquierdo. Conclusión: Los resultados sugieren que la automonitorización de la temperatura del pie por parte del paciente diabético podría ayudar a reducir la alta incidencia de complicaciones en el pie diabético.

Routine delirium monitoring in a UK critical care unit

Introduction Delirium in the intensive care unit (ICU) is associated with increased morbidity and mortality. Using an assessment tool has been shown to improve the ability of clinicians in the ICU to detect delirium. The confusion assessment method for the ICU (CAM-ICU) is a validated delirium-screening tool for critically ill intubated patients. The aim of this project was to establish the feasibility of routine delirium screening using the CAM-ICU and to identify the incidence of delirium in a UK critical care unit.

The Evaluation of an Interdisciplinary Pain Protocol in Long Term Care

Objectives: To evaluate the effectiveness of (1) dissemination strategies to improve clinical practice behaviors (eg, frequency and documentation of pain assessments, use of pain medication) among health care team members, and (2) the implementation of the pain protocol in reducing pain in long term care (LTC) residents. Design: A controlled before-after design was used to evaluate the effectiveness of the pain protocol, whereas qualitative interviews and focus groups were used to obtain additional context-driven data. Setting: Four LTC facilities in southern Ontario, Canada; 2 for the intervention group and 2 for the control group. Participants: Data were collected from 200 LTC residents; 99 for the intervention and 101 for the control group. Intervention: Implementation of a pain protocol using a multifaceted approach, including a site working group or Pain Team, pain education and skills training, and other quality improvement activities. Measurements: Resident pain was measured using 3 assessment tools: the Pain Assessment Checklist for Seniors with Limited Ability to Communicate, the Pain Assessment in the Communicatively Impaired Elderly, and the Present Pain Intensity Scale. Clinical practice behaviors were measured using a number of process indicators; for example, use of pain assessment tools, documentation about pain management, and use of pain medications. A semistructured interview guide was used to collect qualitative data via focus groups and interviews. Results: Pain increased significantly more for the control group than the intervention group over the 1-year intervention period. There were significantly more positive changes over the intervention period in the intervention group compared with the control group for the following indicators: the use of a standardized pain assessment tool and completed admission/initial pain assessment. Qualitative findings highlight the importance of reminding staff to think about pain as a priority in caring for residents and to be mindful of it during daily activities. Using onsite champions, in this case advanced practice nurses and a Pain Team, were key to successfully implementing the pain protocol. Conclusions: These study findings indicate that the implementation of a pain protocol intervention improved the way pain was managed and provided pain relief for LTC residents.

Sensory-motor problems in Autism

Despite being largely characterised as a social and cognitive disorder, strong evidence indicates the presence of significant sensory-motor problems in Autism Spectrum Disorder (ASD). This paper outlines our progression from initial, broad assessment using the Movement Assessment Battery for Children (M-ABC) to subsequent targeted kinematic assessment. In particular, pronounced ASD impairment seen in the broad categories of manual dexterity and ball skills was found to be routed in specific difficulties on isolated tasks, which were translated into focused experimental assessment. Kinematic results from both subsequent studies highlight impaired use of perception-action coupling to guide, adapt and tailor movement to task demands, resulting in inflexible and rigid motor profiles. In particular difficulties with the use of temporal adaption are shown, with "hyperdexterity" witnessed in ballistic movement profiles, often at the cost of spatial accuracy and task performance. By linearly progressing from the use of a standardised assessment tool to targeted kinematic assessment, clear and defined links are drawn between measureable difficulties and underlying sensory-motor assessment. Results are specifically viewed in-light of perception-action coupling and its role in early infant development suggesting that rather than being 'secondary' level impairment, sensory-motor problems may be fundamental in the progression of ASD. This logical and systematic process thus allows a further understanding into the potential route of observable motor problems in ASD; a vital step if underlying motor problems are to be considered a fundamental aspect of autism and allow a route of non-invasive preliminary diagnosis.

Support for the Multidimensional Adolescent Stress Questionnaire in a Sample of Adolescents in the United Kingdom

Adolescence is a time of physical, social and emotional development, and this development can be accompanied by feelings of stress. The Adolescent Stress Questionnaire is a 56-item scale measuring stress in 10 domains. Developed in Australia, the scale has been translated, and its reliability and validity have been tested in a number of countries across Europe, where the 10-factor, 56-item version of the scale has received little support. The present study tested the factor structure, construct validity and reliability in a sample (n=610) of adolescents in the United Kingdom. Support was found for the 10-factor, 56-item version of the scale, and correlations with self-concept measures, sex scores on stress factors and Cronbach's α-values, suggesting that the scale may be a viable assessment tool for adolescent stress. Results for alcohol-specific analyses support the domain-specific nature of the scale. Future work may seek to investigate the stability of age-specific stress domains (e.g. the stress of Emerging Adult Responsibility) in samples that include younger adolescents. 

Have OSCEs come of age in nursing education?

This article is intended to contribute to the current debate as to whether the objective structured clinical examination (OSCE) should become a standard assessment tool for undergraduate nursing education as they currently are for medicine. The authors describe how one UK university developed an OSCE for a nursing undergraduate programme with the aim of emphasising the need for nursing students to be competent in clinical skills and offering a means of standardising the assessment of these skills. There has been an increasing number of research studies carried out in this area at international level and this article's main contribution to the literature is the description of the Angoff standard-setting procedure that was used to calibrate the OSCE at this University and which makes it the first nursing OSCE in the UK to incorporate a scientific standard-setting procedure.

Plain English: Applying Principles to Home School Written Communication Considering Diverse Families

Schools attempting to engage with the families of all learners, including those with culturally and linguistically diverse backgrounds recognize the importance of effective oral and written communication. The aim of this study is to determine if school generated written communication created by an urban school district serving a culturally and linguistically diverse population in the Northeast of the US adhered to the principles of plain English. This exploratory research examined exemplar pieces of written school generated communication, using different forms of linguistic analysis to determine whether the communication contained elements recognized to facilitate or impede the comprehensibility of each piece of communication. Additionally, a text assessment tool which can help schools to analyze the written text communication they send to families was developed and refined.

Traumatic brain injury and co-occurring problems in prison populations: a systematic review.

Background: A growing body of epidemiological research suggests high rates of traumatic brain injury (TBI) in prisoners. The aim of this review is to systematically explore the literature surrounding the rates of TBI and their co-occurrences in a prison population.
Methods: Six electronic databases were systematically searched for articles published between 1980 and 2014. Studies were screened for inclusion based on predetermined criteria by two researchers who independently performed data extraction. Study quality was appraised based on a modified quality assessment tool.
Results: Twenty six studies were included in this review. Quality assessment ranged from 20% (poor) to 80% (good) with an overall average of 60%. Twenty four papers included TBI prevalence rates, which ranged from 5.69%-88%. Seventeen studies explored co-occurring factors including rates of aggression (n=7), substance abuse (n=9), anxiety and depression (n=5), neurocognitive deficits (n=4), and psychiatric conditions (n=3).
Conclusions: The high degree of variation in TBI rates may be attributed to the inconsistent way in which TBI was measured with only seven studies using valid and reliable screening tools. Additionally, gaps in the literature surrounding personality outcomes in prisoners with TBI, female prisoners with TBI, and qualitative outcomes were found.

Impact of non-pharmacological interventions on prevention and treatment of delirium in critically ill patients: protocol for a systematic review of quantitative and qualitative research

Background: Critically ill patients have an increased risk of developing delirium during their intensive care stay.To date, pharmacological interventions have not been shown to be effective for delirium management but non-pharmacological interventions have shown some promise. The aim of this systematic review is to identify effective non-pharmacological interventions for reducing the incidence or the duration of delirium in critically ill patients.

Methods: We will search MEDLINE, EMBASE, CINAHL, Web of Science, AMED, psycINFO and the Cochrane Library.We will include studies of critically ill adults and children. We will include randomised trials and controlled trials which measure the effectiveness of one or more non-pharmacological interventions in reducing incidence or duration ofdelirium in critically ill patients. We will also include qualitative studies that provide an insight into patients and their families’ experiences of delirium and non-pharmacological interventions. Two independent reviewers will assess studies for eligibility, extract data and appraise quality. We will conduct meta-analyses if possible or present results narratively.Qualitative studies will also be reviewed by two independent reviewers, and a specially designed quality assessment tool incorporating the CASP framework and the POPAY framework will be used to assess quality.

Discussion: Although non-pharmacological interventions have been studied in populations outside of intensive care units and multicomponent interventions have successfully reduced incidence and duration of delirium, no systematic review of non-pharmacological interventions specifically targeting delirium in critically ill patients have been undertaken to date. This systematic review will provide evidence for the development of a multicomponent intervention for delirium management of critically ill patients that can be tested in a subsequent multicentre randomised trial.

An evaluation of the Socrative (personal response system) app for increasing student engagement and learning in an undergraduate psychology curriculum.

Personal response systems using hardware such as 'clickers' have been around for some time, however their use is often restricted to multiple choice questions (MCQs) and they are therefore used as a summative assessment tool for the individual student. More recent innovations such as 'Socrative' have removed the need for specialist hardware, instead utilising web-based technology and devices common to students, such as smartphones, tablets and laptops. While improving the potential for use in larger classrooms, this also creates the opportunity to pose more engaging open-response questions to students who can 'text in' their thoughts on questions posed in class. This poster will present two applications of the Socrative system in an undergraduate psychology curriculum which aimed to encourage interactive engagement with course content using real-time student responses and lecturer feedback. Data is currently being collected and result will be presented at the conference.
The first application used Socrative to pose MCQs at the end of two modules (a level one Statistics module and level two Individual Differences Psychology module, class size N≈100), with the intention of helping students assess their knowledge of the course. They were asked to rate their self-perceived knowledge of the course on a five-point Likert scale before and after completing the MCQs, as well as their views on the value of the revision session and any issues that had with using the app. The online MCQs remained open between the lecture and the exam, allowing students to revisit the questions at any time during their revision.
This poster will present data regarding the usefulness of the revision MCQs, the metacognitive effect of the MCQs on student's judgements of learning (pre vs post MCQ testing), as well as student engagement with the MCQs between the revision session and the examination. Student opinions on the use of the Socrative system in class will also be discussed.
The second application used Socrative to facilitate a flipped classroom lecture on a level two 'Conceptual Issues in Psychology' module, class size N≈100). The content of this module requires students to think critically about historical and contemporary conceptual issues in psychology and the philosophy of science. Students traditionally struggle with this module due to the emphasis on critical thinking skills, rather than simply the retention of concrete knowledge. To prepare students for the written examination, a flipped classroom lecture was held at the end of the semester. Students were asked to revise their knowledge of a particular area of Psychology by assigned reading, and were told that the flipped lecture would involve them thinking critically about the conceptual issues found in this area. They were informed that questions would be posed by the lecturer in class, and that they would be asked to post their thoughts using the Socrative app for a class discussion. The level of preparation students engaged in for the flipped lecture was measured, as well as qualitative opinions on the usefulness of the session. This poster will discuss the level of student engagement with the flipped lecture, both in terms of preparation for the lecture, and engagement with questions posed during the lecture, as well as the lecturer's experience in facilitating the flipped classroom using the Socrative platform.

Improving the wellbeing of staff who work in palliative care settings: a systematic review of psychosocial interventions

Background: Staff in palliative care settings perform emotionally demanding roles which may lead to psychological distress including stress and burnout. Therefore, interventions have been designed to address these occupational risks.

Aim: To investigate quantitative studies exploring the effectiveness of psychosocial interventions that attempt to improve psychological wellbeing of palliative care staff.

Design: A systematic review was conducted according to methodological guidance from UK Centre for Reviews and Dissemination.

Data sources: A search strategy was developed based on the initial scans of palliative care studies. Potentially eligible research articles were identified by searching the following databases: CINAHL, MEDLINE (Ovid), PsycINFO and Web of Science. Two reviewers independently screened studies against pre-set eligibility criteria. To assess quality, both researchers separately assessed the remaining studies using the Quality Assessment Tool for Quantitative Studies.

Results: A total of 1786 potentially eligible articles were identified – nine remained following screening and quality assessment. Study types included two randomised controlled trials, two non-randomised controlled trial designs, four one-group pre–post evaluations and one process evaluation. Studies took place in the United States and Canada (5), Europe (3) and Hong Kong (1). Interventions comprised a mixture of relaxation, education, support and cognitive training and targeted stress, fatigue, burnout, depression and satisfaction. The randomised controlled trial evaluations did not improve psychological wellbeing of palliative care staff. Only two of the quasi-experimental studies appeared to show improved staff wellbeing although these studies were methodologically weak.

Conclusion: There is an urgent need to address the lack of intervention development work and high-quality research in this area.

Psicomotricidade e resiliência em crianças brasileiras e portuguesas: um estudo comparativo para a melhoria no ensino-aprendizagem

O presente trabalho tem como objetivo avaliar a eficácia da aplicação de um programa que visa o desenvolvimento psicomotor e a resiliência em crianças brasileiras (de classes desfavorecidas) e portuguesas (meio rural). Foram implementados 3 estudos: no primeiro, exploratório, foi realizado um programa de intervenção na área da resiliência com 76 crianças portuguesas e 151 crianças brasileiras com idades entre os 3 e os 5 anos de idade, divididas em Grupo Experimental (submetido ao programa de intervenção Strong Start Pré- K, da Universidade do Oregon, adaptado às realidades portuguesa e brasileira) e Grupo Controlo (sem intervenção),avaliadas pelo questionário WeBeST (Well-Being Screening Tool) antes e depois da intervenção. O segundo estudo realizado numa ONG brasileira pretende avaliar o efeito da psicomotricidade e foi dividido em duas fases: fase A, que contou 32 crianças brasileiras de 5 anos de idade, que frequentam a Instituição em período integral e 28 crianças que frequentam em meio período. Na fase B foi aplicado um programa de intervenção (nas 28 crianças da fase A) para se avaliar o efeito dessa intervenção. O instrumento de avaliação utilizado na área foi o Inventário Portage, adaptado e operacionalizado para a população brasileira, que consta de 580 itens divididos em seis áreas (Autocuidados, Cognição, Desenvolvimento Motor, Estimulação Infantil, Linguagem e Socialização). O terceiro estudo avaliou apenas nas crianças de 5 anos, os efeitos da resiliência e psicomotricidade nas 28 crianças brasileiras da fase A e B (do estudo 2) e em 35 crianças portuguesas (do estudo 1). Pudemos constatar no primeiro estudo que quer as crianças portuguesas, quer as brasileiras submetidas ao programa de intervenção na área da resiliência obtiveram melhores resultados que as não submetidas ao mesmo programa. Quanto aos resultados obtidos na fase A do segundo estudo na área da psicomotricidade, as crianças da ONG brasileira, que frequentavam o período integral obtiveram melhores resultados que as não requentavam. Já na fase B, estas ao serem submetidas ao programa de intervenção específico, obtiveram resultados significativos, o que sugere que o Programa de intervenção foi eficaz, quer para as crianças que o tiveram anteriormente no período integral, quer para as que foram submetidas a ele na fase posterior. No último estudo, as crianças brasileiras apresentaram melhores resultados que as portuguesas. Não foi possível fazer um estudo comparativo entre Portugal e Brasil, relativamente à área da psicomotricidade, visto que na realidade portuguesa, desde os anos 70 é obrigatória na educação pré-escolar a psicomotricidade. São referidas algumas implicações psicopedagógicas resultantes deste tipo de intervenção, perspetivando a melhoria da qualidade de ensino e aprendizagem e o desenvolvimento de personalidades resilientes das crianças.

Gestão da sustentabilidade nas organizações: uma nova metodologia

O presente trabalho pretende auxiliar o processo de consolidação do conceito de sustentabilidade no seio das organizações. Partindo de ferramentas de gestão e avaliação já existentes, esta tese sugere a sua integração numa única metodologia, ultrapassando desse modo as limitações e potenciando as suas capacidades enquanto ferramentas isoladas. O modelo proposto para o Sistema de Gestão da Sustentabilidade (SGS) integra assim: o conceito de melhoria contínua característico dos sistemas de gestão normalizados; a capacidade de tradução da perspetiva estratégica da gestão para o plano operacional, característica do Business Scorecard (BSC); e, por fim, a avaliação emergética é ainda utilizada como uma ferramenta de avaliação da sustentabilidade de sistemas. Um objetivo secundário desta tese prende-se com o desenvolvimento de um procedimento para a realização da análise emergética de um sistema. Depois de analisada a literatura referente à utilização da análise emergética, identificou-se como necessária a definição de um procedimento normalizado, adotando um conjunto de tarefas e um formato de apresentação de resultados que permita disseminar o conceito e tornar a ferramenta mais “utilizável”. Por outro lado, procurou-se dotar o procedimento com um conjunto de indicações que permitem ultrapassar limitações e inconvenientes apontados pelos críticos mas também utilizadores do método, nomeadamente: problemas de dupla contagem, cálculo da incerteza da análise e critérios de qualidade da informação utilizada. O modelo dos sistemas de gestão normalizados apresenta um papel central na metodologia proposta. O conceito de “melhoria contínua” afigura-se como fundamental num sistema que pretende implementar o conceito “desenvolvimento sustentável” e avaliar o seu desempenho à luz do mesmo. Assim, o ciclo Plan-Do-check-Act (PDCA) deve ser utilizado para implementar o SGS de acordo com uma Política para a Sustentabilidade que a organização deve desenvolver. Definida a Política, o modelo baseia-se então no ciclo PDCA: fase de planeamento; fase de implementação; fase de verificação; e fase de revisão. É na fase de planeamento do SGS que se sugere a introdução das outras duas ferramentas: a análise emergética (AEm) e o BSC. A fase de planeamento do modelo de SGS proposto neste trabalho foi aplicada à Universidade de Aveiro (UA), incluindo a definição de uma Política para a Sustentabilidade e o planeamento estratégico e operacional. A avaliação emergética à UA foi realizada recorrendo ao procedimento desenvolvido nesta tese e permitiu caracterizar e avaliar os fluxos de recursos que a “alimentam” sob uma só unidade, atribuindo deste modo graus de importância aos diferentes recursos utilizados. A informação representa 96% do total de recursos utilizados na UA, quando avaliados sob o ponto de vista emergética. Para além da informação, os fluxos financeiros representam a maior fatia do orçamento emergético da UA, grande parte dos quais serve para sustentar os serviços prestados pelo corpo docente da UA. Analisando valores históricos de 3 indicadores de desempenho emergético, observa-se que a UA não regista uma evolução positiva em nenhum dos indicadores: a emergia utilizada nos edifícios tem-se mantido mais ou menos constante; a retribuição emergética da UA para a sociedade, avaliada sobre a forma de diplomados, tem diminuído; e a relação emergética entre professores e alunos tem também diminuído, facto que pode refletir-se na qualidade dos “produtos” da UA. Da aplicação do SGS à UA regista-se: a adequabilidade do ciclo PDCA à implementação de um SGS; a capacidade da AEm “obrigar” a organização a adotar uma abordagem sistémica da sua atividade, resultando numa visão mais aprofundada da sua relação com o contexto ambiental, económico e social em que se insere; a importância da visão estratégica e da sua tradução em termos operacionais na fase de planeamento de um SGS; e, por fim, a capacidade de adaptação e dupla funcionalidade (implementação e avaliação) do modelo de SGS proposto. A metodologia de SGS proposta nesta tese, sendo direcionada para todo o tipo de organizações, não se desvirtua quando aplicada ao contexto específico das instituições de ensino superior e permite implementar e avaliar o conceito “desenvolvimento sustentável” nas quatro dimensões da universidade (Educação, Investigação, Operação; Relação com as partes interessadas).

Gestão de resíduos para uma construção sustentável

Os resíduos sólidos (RS) têm vindo a aumentar em quantidade e diversidade nas últimas décadas em todo o mundo, em resultado da explosão demográfica, do crescimento económico e do aumento da construção, acentuando-se também a produção de resíduos perigosos. Por estas mesmas razões têm surgido limitações do espaço disponível para deposição final de RS. A prática atual no sector da construção pode ser alterada através da introdução de uma gestão eficiente, optimizadora de custos, com a produção de menos resíduos produzidos e também através da implementação de medidas preventivas de produção de resíduos nas obras. Pretende-se, no âmbito deste trabalho, abordar a problemática da gestão de resíduos de construção em obra e contribuir para alterar a situação descrita, apresentando e validando ferramentas a utilizar na gestão de RS. O principal objetivo do trabalho é avaliar os impactes ambientais associados à gestão dos resíduos produzidos na obra na fase de construção. Nas obras em estudo foi recolhida informação sobre os resíduos (quantidades e tipologia) e analisada, tratada com a finalidade de criar uma ferramenta indispensável na gestão de resíduos de construção e compilado o inventário dos resíduos. Após esta compilação, procedeu-se à avaliação dos impactes. A aplicação da ferramenta de avaliação de ciclo de vida permitem avaliar o impacte das decisões na sustentabilidade da construção, nomeadamente no que diz respeito à geração de resíduos.
