Combining WLAN fingerprint-based localization with sensor data for indoor navigation using mobile devices

This project proposes an approach for supporting Indoor Navigation Systems using Pedestrian Dead Reckoning-based methods and by analyzing motion sensor data available in most modern smartphones. Processes suggested in this investigation are able to calculate the distance traveled by a user while he or she is walking. WLAN fingerprint- based navigation systems benefit from the processes followed in this research and results achieved to reduce its workload and improve its positioning estimations.

Complex networks and data mining: toward a new perspective for the understanding of complex systems

Complex systems, i.e. systems composed of a large set of elements interacting in a non-linear way, are constantly found all around us. In the last decades, different approaches have been proposed toward their understanding, one of the most interesting being the Complex Network perspective. This legacy of the 18th century mathematical concepts proposed by Leonhard Euler is still current, and more and more relevant in real-world problems. In recent years, it has been demonstrated that network-based representations can yield relevant knowledge about complex systems. In spite of that, several problems have been detected, mainly related to the degree of subjectivity involved in the creation and evaluation of such network structures. In this Thesis, we propose addressing these problems by means of different data mining techniques, thus obtaining a novel hybrid approximation intermingling complex networks and data mining. Results indicate that such techniques can be effectively used to i) enable the creation of novel network representations, ii) reduce the dimensionality of analyzed systems by pre-selecting the most important elements, iii) describe complex networks, and iv) assist in the analysis of different network topologies. The soundness of such approach is validated through different validation cases drawn from actual biomedical problems, e.g. the diagnosis of cancer from tissue analysis, or the study of the dynamics of the brain under different neurological disorders.

A DSL for querying building data streams of energy, eeather and occupation data

The superfluous consumption of energy is faced by the modern society as a Socio-Economical and Environmental problem of the present days. This situation is worsening given that it is becoming clear that the tendency is to increase energy price every year. It is also noticeable that people, not necessarily proficient in technology, are not able to know where savings can be achieved, due to the absence of accessible awareness mechanisms. One of the home user concerns is to balance the need of reducing energy consumption, while producing the same activity with all the comfort and work efficiency. The common techniques to reduce the consumption are to use a less wasteful equipment, altering the equipment program to a more economical one or disconnecting appliances that are not necessary at the moment. However, there is no direct feedback from this performed actions, which leads to the situation where the user is not aware of the influence that these techniques have in the electrical bill. With the intension to give some control over the home consumption, Energy Management Systems (EMS) were developed. These systems allow the access to the consumption information and help understanding the energy waste. However, some studies have proven that these systems have a clear mismatch between the information that is presented and the one the user finds useful for his daily life, leading to demotivation of use. In order to create a solution more oriented towards the user’s demands, a specially tailored language (DSL) was implemented. This solution allows the user to acquire the information he considers useful, through the construction of questions about his energy consumption. The development of this language, following the Model Driven Development (MDD) approach, took into consideration the ideas of facility managers and home users in the phases of design and validation. These opinions were gathered through meetings with experts and a survey, which was conducted to the purpose of collecting statistics about what home users want to know.

Integrated data model and DSL modifications

Companies are increasingly more and more dependent on distributed web-based software systems to support their businesses. This increases the need to maintain and extend software systems with up-to-date new features. Thus, the development process to introduce new features usually needs to be swift and agile, and the supporting software evolution process needs to be safe, fast, and efficient. However, this is usually a difficult and challenging task for a developer due to the lack of support offered by programming environments, frameworks, and database management systems. Changes needed at the code level, database model, and the actual data contained in the database must be planned and developed together and executed in a synchronized way. Even under a careful development discipline, the impact of changing an application data model is hard to predict. The lifetime of an application comprises changes and updates designed and tested using data, which is usually far from the real, production, data. So, coding DDL and DML SQL scripts to update database schema and data, is the usual (and hard) approach taken by developers. Such manual approach is error prone and disconnected from the real data in production, because developers may not know the exact impact of their changes. This work aims to improve the maintenance process in the context of Agile Platform by Outsystems. Our goal is to design and implement new data-model evolution features that ensure a safe support for change and a sound migration process. Our solution includes impact analysis mechanisms targeting the data model and the data itself. This provides, to developers, a safe, simple, and guided evolution process.

Sistema de deteção de eventos adversos baseado num data warehouse

RESUMO - A Segurança do Doente tem assumido uma relevância crescente nas organizações de saúde, resultado da divulgação de diversos estudos que revelaram a magnitude deste problema e simultaneamente, de uma maior pressão por parte da opinião pública e da comunicação social. Este estudo pretende desenvolver e avaliar a performance de um sistema eletrónico de deteção de eventos adversos, baseado num Data Warehouse, por comparação com os resultados obtidos pela metodologia tradicional de revisão dos registos clínicos. O objetivo principal do trabalho consistiu em identificar um conjunto de triggers / indicadores de alerta que permitam detetar potenciais eventos adversos mais comuns. O sistema desenvolvido apresentou um Valor Preditivo Positivo de 18.2%, uma sensibilidade de 65.1% e uma especificidade de 68.6%, sendo constituído por nove indicadores baseados em informação clínica e 445 códigos do ICD-9-CM, relativos a diagnósticos e procedimentos. Apesar de terem algumas limitações, os sistemas eletrónicos de deteção de eventos adversos apresentam inúmeras potencialidades, nomeadamente a utilização em tempo real e em complemento a metodologias já existentes. Considerando a importância da problemática em análise e a necessidade de aprofundar os resultados obtidos neste trabalho de projeto, seria relevante a sua extensão a um universo mais alargado de instituições hospitalares, estando a sua replicabilidade facilitada, uma vez que o Data Warehouse tem por base um conjunto de aplicações disseminadas a nível nacional. O desenvolvimento e a consolidação dos sistemas eletrónicos de deteção de eventos adversos constitui inegavelmente uma área de futuro, com reflexos ao nível da melhoria da informação existente nas organizações e que contribuirá decisivamente para a melhoria dos cuidados de saúde prestados aos doentes.

SDAR: a package for plotting and analyzing stratigraphy data in R

Stratigraphic Columns (SC) are the most useful and common ways to represent the eld descriptions (e.g., grain size, thickness of rock packages, and fossil and lithological components) of rock sequences and well logs. In these representations the width of SC vary according to the grain size (i.e., the wider the strata, the coarser the rocks (Miall 1990; Tucker 2011)), and the thickness of each layer is represented at the vertical axis of the diagram. Typically these representations are drawn 'manually' using vector graphic editors (e.g., Adobe Illustrator®, CorelDRAW®, Inskape). Nowadays there are various software which automatically plot SCs, but there are not versatile open-source tools and it is very di cult to both store and analyse stratigraphic information. This document presents Stratigraphic Data Analysis in R (SDAR), an analytical package1 designed for both plotting and facilitate the analysis of Stratigraphic Data in R (R Core Team 2014). SDAR, uses simple stratigraphic data and takes advantage of the exible plotting tools available in R to produce detailed SCs. The main bene ts of SDAR are: (i) used to generate accurate and complete SC plot including multiple features (e.g., sedimentary structures, samples, fossil content, color, structural data, contacts between beds), (ii) developed in a free software environment for statistical computing and graphics, (iii) run on a wide variety of platforms (i.e., UNIX, Windows, and MacOS), (iv) both plotting and analysing functions can be executed directly on R's command-line interface (CLI), consequently this feature enables users to integrate SDAR's functions with several others add-on packages available for R from The Comprehensive R Archive Network (CRAN).

Analyzing Geospatial patterns of syrian refugee flows in southeastern Turkey by use of remote sensing and complementary data

Crisis-affected communities and global organizations for international aid are becoming increasingly digital as consequence geotechnology popularity. Humanitarian sector changed in profound ways by adopting new technical approach to obtain information from area with difficult geographical or political access. Since 2011, turkey is hosting a growing number of Syrian refugees along southeastern region. Turkish policy of hosting them in camps and the difficulty created by governors to international aid group expeditions to get information, made such international organizations to investigate and adopt other approach in order to obtain information needed. They intensified its remote sensing approach. However, the majority of studies used very high-resolution satellite imagery (VHRSI). The study area is extensive and the temporal resolution of VHRSI is low, besides it is infeasible only using these sensors as unique approach for the whole area. The focus of this research, aims to investigate the potentialities of mid-resolution imagery (here only Landsat) to obtain information from region in crisis (here, southeastern Turkey) through a new web-based platform called Google Earth Engine (GEE). Hereby it is also intended to verify GEE currently reliability once the Application Programming Interface (API) is still in beta version. The finds here shows that the basic functions are trustworthy. Results pointed out that Landsat can recognize change in the spectral resolution clearly only for the first settlement. The ongoing modifications vary for each case. Overall, Landsat demonstrated high limitations, but need more investigations and may be used, with restriction, as a support of VHRSI.

Identifying the urban communities of New York City using bikeshare data from NYC citibike

This study identifies a measure of the cultural importance of an area within a city. It does so by making use of origindestination trip data and the bike stations of the bike share system in New York City as a proxy to study the city. Rarely is movement in the city studied at such a small scale. The change in strength of the similarity of movement between each station is studied. It is the first study to provide this measure of importance for every point in the system. This measure is then related to the characteristics which make for vibrant city communities, namely highly mixed land use types. It reveals that the spatial pattern of important areas remains constant over differing time periods. Communities are then characterised by the land uses surrounding these stations with high measures of importance. Finally it identifies the areas of global cultural importance alongside the areas of local importance to the city.

Popular music exhibitions in Portugal: practices of representation from 2007 to 2013

This thesis focuses on the representation of Popular Music in museums by mapping, analyzing, and characterizing its practices in Portugal at the beginning of the 21st century. Now that museums' ability to shape public discourse is acknowledged, the examination of popular music's discourses in museums is of the utmost importance for Ethnomusicology and Popular Music Studies as well as for Museum Studies. The concept of 'heritage' is at the heart of this processes. The study was designed with the aim of moving the exhibiting of popular music in museums forward through a qualitative inquiry of case studies. Data collection involved surveying pop-rock music exhibitions as a qualitative sampling of popular music exhibitions in Portugal from 2007 to 2013. Two of these exhibitions were selected as case studies: No Tempo do Gira-Discos: Um Percurso pela Produção Fonográfica Portuguesa at the Museu da Música in Lisbon in 2007 (also Faculdade de Letras, 2009), and A Magia do Vinil, a Música que Mudou a Sociedade at the Oficina da Cultura in Almada in 2008 (and several other venues, from 2009 to 2013). Two specific domains were observed: popular music exhibitions as instances of museum practice and museum professionals. The first domain encompasses analyzing the types of objects selected for exhibition; the interactive museum practices fostered by the exhibitions; the concepts and narratives used to address popular music discursively, as well as the interpretative practices they allow. The second domain, focuses museum professionals and curators of popular music exhibitions as members of a group, namely their goals, motivations and perspectives. The theoretical frameworks adopted were drawn from the fields of ethnomusicology, popular music studies, and museum studies. The written materials of the exhibitions were subjected of methods of discourse analysis methods. Semi-structured interviews with curators and museum professional were also conducted and analysed. From the museum studies perspective, the study research suggests that the practice adopted by popular music museums largely matches that of conventional museums. From the ethnomusicological and popular music studies stand point, the two case studies reveal two distinct conceptual worlds: the first exhibition, curated by an academic and an independent researcher, points to a mental configuration where popular music is explained through a framework of genres supported by different musical practices. Moreover, it is industry actors such as decision makers and gatekeepers that govern popular music, which implies that the visitors' romantic conception of the musician is to some extent dismantled; the second exhibition, curated by a record collector and specialist, is based on a more conventional process of the everyday historical speech that encodes a mismatch between “good” and “bad music”. Data generated by a survey shows that only one curator, in fact that of my first case study, has an academic background. The backgrounds of all the others are in some way similar to the curator of the second case study. Therefore, I conclude that the second case study best conveys the current practice of exhibiting Popular Music in Portugal.

The role of qualitative data and systems thinking in addressing service decline in market towns

Retail services are a main contributor to municipal budget and are an activity that affects perceived quality-of-life, especially for those with mobility difficulties (e.g. the elderly, low income citizens). However, there is evidence of a decline in some of the services market towns provide to their citizens. In market towns, this decline has been reported all over the western world, from North America to Australia. The aim of this research was to understand retail decline and enlighten on some ways of addressing this decline, using a case study, Thornbury, a small town in the Southwest of England. Data collected came from two participatory approaches: photo-surveys and multicriteria mapping. The interpretation of data came from using participants as analysts, but also, using systems thinking (systems diagramming and social trap theory) for theory building. This research moves away from mainstream economic and town planning perspectives by making use of different methods and concepts used in anthropology and visual sociology (photo-surveys), decision-making and ecological economics (multicriteria mapping and social trap theory). In sum, this research has experimented with different methods, out of their context, to analyse retail decline in a small town. This research developed a conceptual model for retail decline and identified the existence of conflicting goals and interests and their implications for retail decline, as well as causes for these. Most of the potential causes have had little attention in the literature. This research also identified that some of the measures commonly used for dealing with retail decline may be contributing to the causes of retail decline itself. Additionally, this research reviewed some of the measures that can be used to deal with retail decline, implications for policy-making and reflected on the use of the data collection and analysis methods in the context of small to medium towns.

Use of Poisson spatiotemporal regression models for the Brazilian Amazon Forest: malaria count data

INTRODUCTION: Malaria is a serious problem in the Brazilian Amazon region, and the detection of possible risk factors could be of great interest for public health authorities. The objective of this article was to investigate the association between environmental variables and the yearly registers of malaria in the Amazon region using Bayesian spatiotemporal methods. METHODS: We used Poisson spatiotemporal regression models to analyze the Brazilian Amazon forest malaria count for the period from 1999 to 2008. In this study, we included some covariates that could be important in the yearly prediction of malaria, such as deforestation rate. We obtained the inferences using a Bayesian approach and Markov Chain Monte Carlo (MCMC) methods to simulate samples for the joint posterior distribution of interest. The discrimination of different models was also discussed. RESULTS: The model proposed here suggests that deforestation rate, the number of inhabitants per km², and the human development index (HDI) are important in the prediction of malaria cases. CONCLUSIONS: It is possible to conclude that human development, population growth, deforestation, and their associated ecological alterations are conducive to increasing malaria risk. We conclude that the use of Poisson regression models that capture the spatial and temporal effects under the Bayesian paradigm is a good strategy for modeling malaria counts.

Relationship between national culture, democracy and environmental performance: A panel data analysis

This paper demonstrates the significance of culture in examining the relationshipbetween democratic capital and environmental performance.The aim is to examine the relationship among scores on the Environmental Performance Index and the two dimensions of cross cultural variation suggested by Ronald Inglehart and Christian Welzel. Significantional interrelationships among democracy, cultural and environmental sustaintability measures could be found, following the regression results. Firstly, higher levels of democratic capital stock are associated with better environmental performance. Secondly importance to distinguish between cultural groups could be confirmed.

A method to correct the flow distortion of offshore wind data using CFD simulation and experimental wind tunnel tests

The assessment of wind energy resource for the development of deep offshore wind plants requires the use of every possible source of data and, in many cases, includes data gathered at meteorological stations installed at islands, islets or even oil platforms—all structures that interfere with, and change, the flow characteristics. This work aims to contribute to the evaluation of such changes in the flow by developing a correction methodology and applying it to the case of Berlenga island, Portugal. The study is performed using computational fluid dynamic simulations (CFD) validated by wind tunnel tests. In order to simulate the incoming offshore flow with CFD models a wind profile, unknown a priori, was established using observations from two coastal wind stations and a power law wind profile was fitted to the existing data (a=0.165). The results show that the resulting horizontal wind speed at 80 m above sea level is 16% lower than the wind speed at 80 m above the island for the dominant wind direction sector.

Integration of speech-processing technologies into Activobank's client interaction process

This dissertation analyzes the possibilities of utilizing speech-processing technologies to transform the user experience of ActivoBank’s customers while using remote banking solutions. The technologies are examined through different criteria to determine if they support the bank’s goals and strategy and whether they should be incorporated in the bank’s offering. These criteria include the alignment with ActivoBank’s values, the suitability of the technology providers, the benefits these technologies entail, potential risks, appeal to the customers and impact on customer satisfaction. The analysis suggests that ActivoBank might not be in a position to adopt these technologies at this point in time.

Objetivo secundário: • Estudar a efetividade e concordância inter-observador da aplicação da CIF, com base na leitura dos dados obtidos em avaliação efetuada com os instrumentos referidos, por duas observadoras independentes, em contexto de articulação saúde, respetivamente educação e segurança social Métodos • Estudo observacional, descritivo, transversal e prospetivo. • Foi estudada uma amostra de conveniência 355 crianças, num período de três anos (Maio de 2010 a 30 de Abril de 2013), com patologia da área da pediatria do neurodesenvolvimento (total de 4000 consultas) no Centro de Desenvolvimento (CD) do Hospital de Dona Estefânia (HDE), Centro Hospitalar de Lisboa Central, EPE (CHLC, EPE). • Critérios de inclusão: crianças de ambos os sexos, observadas no CD do HDE, CHLC (primeiras consultas e consultas de reavaliação) com idade ≥12 meses e ≤17 anos e incapacidade intelectual definida de acordo com os critérios da DSM-IV-TR, DSM 5 e CID-10. • Critérios de exclusão: crianças com autismo, perturbações específicas da linguagem, hiperatividade, défice de atenção e concentração, défices sensoriais congénitos (baixa visão e ou audição), ou com outros diagnósticos de perturbações de neurodesenvolvimento. • O estudo teve duas fases: na primeira, a investigadora principal colheu ou atualizou a história clínica, observou clinicamente as crianças solicitando os exames complementares considerados necessários e foi efetuada avaliação psicológica com os instrumentos adiante descritos, pela mesma psicóloga clínica, devidamente credenciada, e com larga experiência nas escalas referidas. Com base nos dados colhidos, quer por observação direta, quer através dos resultados das escalas Griffiths e WISC – III, a investigadora aplicou a CIF-CJ, circunscrita aos domínios e funções (variáveis): 1. FUNÇÕESMENTAIS GLOBAIS (b110- Funções da consciência, b114- Funções da orientação no espaço e no tempo, b117 – Funções intelectuais, b122- Funções psicossociais globais, b125- Funções intrapessoais, b126- Funções do temperamento e da personalidade); 2.FUNÇÕES MENTAIS ESPECÌFICAS (b140- funções da atenção, b147- Funções psicomotoras, b152- Funções emocionais, b156- Funções da perceção, b163- Funções cognitivas básicas, b164- Funções cognitivas de nível superior, b167- Funções mentais da linguagem 3. FUNÇÕES DA VOZ E DA FALA (b320- Funções da articulação, b330- Funções da fluência e do ritmo da fala). Numa segunda fase, foi solicitada a colaboração de duas co-investigadoras, com formação específica nas escalas utilizadas e na CIF-CJ, a aplicação da CIF nos mesmos domínios e funções. Estas observadoras não efetuaram observações diretas das crianças envolvidas. • Para efetuar a análise estatística e analisar a relação entre os qualificadores (0 a 4) das variáveis da CIF em estudo (b117, b122, b147, b163, b164, b167, b320 e b330) e os instrumentos psicométricos (escalas de Griffiths e WISC III), que constitui a primeira parte do estudo, recorreu-se à técnica estatística não paramétrica do coeficiente de correlação de Spearman, que quantifica a intensidade e sinal da eventual correlação existente entre as variáveis em estudo. • Para determinar as correlações referentes à segunda parte do estudo, foram utilizados os programas SPSS®, (IBM SPSS Statistics) e Statistica® (StatSoft, Inc., 2011). STATISTICA (data analysis software system, version 10. www.statsoft.com.), tendo-se dado preferência aos gráficos deste último. Resultados 1. Observou-se um predomínio do sexo masculino (relação de 1:1,9); relativamente à idade no momento de avaliação, 242 crianças (68,1%) tinham entre zero e seis anos e, dentro destas, a maioria (189) situava-se entre os três e os seis anos. 2. De acordo com a DSM-IV e DSM-5, 261 (73,4%) crianças apresentavam incapacidade intelectual ligeira. 3. A avaliação da competência intelectual pelas escalas de Ruth Griffiths e WISC III (QI), revelaram correlação negativa predominantemente forte e muito forte (índice de Spearman) com os qualificadores das funções do corpo estudadas (funções mentais, mentais específicas e da voz). Os resultados obtidos pela co-investigadora A foram sobreponíveis aos da investigadora principal. Os resultados obtidos pela co-investigadora B revelaram correlação negativa moderada e forte, correlação inferior à da investigadora principal; Conclusões Os resultados permitem inferir que as escalas de Ruth Griffiths e WISC-III são instrumentos adequados para caracterizar a incapacidade intelectual na CIF-CJ; a concordância inter-observador, moderada, nos qualificadores atribuídos nas funções em análise pela investigadora e co-investigadoras, permite concluir que as escalas de Ruth Griffiths e WISC IIIl são bons instrumentos para caracterizar os qualificadores nos domínios e funções estudados, por diferentes grupos de profissionais ligados à infância. Subsistem dificuldades na diferenciação entre qualificadores, designadamente entre os qualificadores 1 e 2, o que tem necessariamente implicações na elegibilidade das crianças para os apoios preconizados pelo DL 3/2008. ------------------------ ABSTRACT: Main objective • To determine the consistency of the use of assessment tools for intellectual ability - Griffiths and WISC III scales - in the context of domains and qualifiers for the ICF-CY, restricted to the mental functions of the body. Secondary objective • Studying the effectiveness and inter-observer concordance concerning the application of the ICF, based on the data recovered from the assessment made with the mentioned instruments, carried out by two independent observers including their perspective on health, education and social security. Methods • Observational, descriptive, cross-sectional and prospective study. • A convenience sample of 355 children was studied over a period of three years (May 2010 to April 2013), with a pathology in the area of pediatric neurodevelopment – intellectual disability (total of 4000 consultations, including first consultations and revaluations) were observed in the Development Centre (CD) in Hospital de Dona Estefânia (HDE), Centro Hospitalar de Lisboa Central, EPE (CHLC). • Inclusion criteria: children of both sexes aged ≥12 months and years ≤17 and intellectual disability defined according to the criteria in the DSM-IV-TR, DSM 5 and ICD-10. • Exclusion criteria: children with autism; specific language impairment, hyperactivity; attention deficit disorder; severe birth sensory deficits (eg, impaired vision and hearing); amongst other diagnoses for neurodevelopmental disorders. • The study was conducted in two phases: in the first phase the principal investigator collected or updated medical history, clinically observed children requesting additional investigations if she deemed necessary. Psychological evaluation was performed by a single, duly licensed clinical psychologist with extensive experience in the referred scales using the instruments described below. Based on data collected, either by direct observation or through the results of Griffiths scales and WISC - III, the researcher applied the ICF-CY confined to the following fields and functions (variables): 1. GLOBAL MENTAL FUNCTIONS (b110- functions of consciousness, b114- Functions referring to space and time orientation , b117 - intellectual functions, b122- global psychosocial functions, b125- intrapersonal functions, b126- functions related to temperament and personality); 2. SPECIFIC MENTAL FUNCTIONS ( b140- attention functions, b147-psychomotor functions, b152- Emotional functions, b156- perception functions, b163- basic cognitive functions and cognitive functions b164- top level b167- language related mental functions. ) 3. VOICE AND SPEECH FUNCTIONS (b320-articulation functions, b330- fluency and rhythm of speech functions). • In the second phase, two co-investigators, with specific training on the scales used and the ICF-CY have applied the ICF in the domains and functions mentioned above, based on the scales results. These co-investigators did not make any direct observation of the studied children. • To perform the statistical analysis and analyze the relationship between the qualifiers (0-4) of the variables in the ICF study (b117, b122, b147, B163, B164, b167, b320 and B330) and psychometric instruments (Griffiths scale and WISC III), which is the first part of the study, the statistical technique of non-parametric Spearman correlation coefficient was used, which quantifies the strength and sign of the possible correlation between the variables under study. • For submission of correlations related to the second part of the study, SPSS (IBM SPSS) and Statistica (StatSoft, Inc., 2011) programs were used. STATISTICA (data analysis software system, version 10 www.statsoft.com.). Preference was given to graphs computed in Statistica. Results • Male predominated (ratio of 1: 1.9). 242 children (68.1% of the sample) were aged between zero and six years and, among these, the majority (189) was aged largest number between three and six years. • According to the DSM-IV and DSM-5, 261 (73.4%) children had mild intellectual disability. The correlation between the assessment of intellectual competence by Ruth Griffiths scales and WISC III (QI), was predominantly negative strong and very strong correlation with the qualifiers of body functions studied (specific mental functions, mental and voice functions using Spearman index). The levels of correlation obtained by the co-investigatores were in agreeance with the results from the principal investigator. The results obtained by co-investigator B showed moderate to strong negative correlation, levels that were lower to the those registered by the principal investigator; Conclusions These results indicate that Ruth Griffiths and WISC-III scales are adequate tools to characterize intellectual disability in the ICF-CY; moderate inter-observer agreement in the qualifiers assigned the functions under analysis by the researcher and co-researchers, shows that the scales are also good tools to measure CIF qualifyers by diferent technicians with different professional orientations, related to children. However, there are still difficulties in differentiating qualifiers, namely between qualifiers 1/2 and 3/4, which necessarily has implications for the eligibility of children for the state support advocated by the Portuguese Decret Law 3/2008.
