  2. Assisting European Portuguese teaching: linguistic features extraction and automatic readability classifier

    Curto, Pedro; Mamede, Nuno; Baptista, Jorge
    This paper describes two automatic systems: a linguistic features extractor and a text readability classifier for European Portuguese texts. Its main goal is to assist the selection of adequate reading materials to support Portuguese teaching, especially as a second language. To the feature extraction from texts, the system uses several Natural Language Processing (NLP) tools. Currently, 52 features are extracted: parts-of-speech (POS), syllables, words, chunks and phrases, averages and frequencies, among others. A classifier was created using these features and a corpus, previously annotated readability level, adopting the five-levels language classification official standard for Portuguese as Second Language. In a...

  3. Ceramic technology and resource use during the early neolithic in Central-Southern Portugal

    Masucci, M.; Carvalho, António Faustino
    Petrographic analysis of 49 sediments and 63 Neolithic ceramics from eight sites of Estremadura and six sites of the Algarve of central and southern Portugal, respectively, discerned distinct production technologies for each area. Raw materials available near archaeological sites were utilized. Fabrics that do not correspond to regionally available materials, however, indicate imports or migration. This suggests the existence of bidirectional maritime routes rather than south-north only, as predicted in current models of the neolithization of coastal Portugal. Seven ceramics and seven sediments were selected for elemental analysis. The results supported the patterns in the petrographic analysis.

  5. Time perception in mild cognitive impairment: interval length and subjective passage of time

    Coelho, Sara; Guerreiro, Manuela; Chester, Catarina; Silva, Dina; Maroco, João; Coelho, Miguel; Paglieri, Fabio; de Mendonça, Alexandre
    Objectives Patients with mild cognitive impairment (MCI) may have difficulties in time perception, which in turn might contribute to some of their symptoms, especially memory deficits. The aim of this study was to evaluate perception of interval length and subjective passage of time in MCI patients as compared to healthy controls. Methods Fifty-five MCI patients and 57 healthy controls underwent an experimental protocol for time perception on interval length, a questionnaire for the subjective passage of time and a neuropsychological evaluation. Results MCI patients presented no changes in the perception of interval length. However, for MCI patients, time seemed to...

  6. All different, all equal: Evidence of a heterogeneous Neolithic population at the Bom Santo Cave necropolis (Portugal)

    Goncalves, D.; Granja, Raquel; Alves-Cardoso, F.; Carvalho, A. F.
    The objective of this paper was to contribute to the discussion regarding the socio-political organization of south-western Iberian Middle Neolithic populations. To that end, the preservation and distribution of human remains and the dispersion of grave goods within two rooms of the Born Santo Cave (Rooms A and B) were investigated and combined with, genetic and isotopic data previously published. Grave goods distribution and skeletal analyses highlighted an important diversity in terms of funerary practices thus corroborating data from ancient DNA and Sr/O isotopic analyses that suggested a great genetic and geographic diversity. Grave goods presented an uneven spatial distribution...

  7. The contribution of professional coach for emotional and psychological adjustment of soccer player

    Silva, José Eduardo; Vieira, Luís Sérgio; Gomes, Alexandra
    ABSTRACT: The aim of this study was to explore the perception of professional soccer coaches about their contribution to the psychological and emotional player's adjustment. It is a qualitative study and dates were obtained by semi-structured interviews conducted with ten professional soccer coaches. A descendent hierarchical corpus identified four classes organized into two themes. Theme 1 (the coach and soccer player toward competition demands) corresponds to class 1 (soccer coach profile) and 2 (soccer player in competition), and theme 2 (the coach and player psychological dimension), class 3 (player psychological dimension) and 4 (relationship coach-player).Results allowed us to understand that...

  8. One for all and all for one: Linear regression from the mass of individual bones to assess human skeletal mass completeness

    Gonçalves, David; Coelho, João d'Oliveira; Acosta, Maria A.; Coelho, Catarina; Curate, Francisco; Ferreira, Maria Teresa; Gouveia, Márcia; Makhoul, Calil; Pinto, Débora; Oliveira-Santos, Inês; Vassalo, Ana R.; Navega, David; Cunha, Eugénia
    ObjectivesComplete and accurate human skeletal inventory is seldom possible in archaeological and forensic cases involving severe fragmentation. In such cases, skeletal mass comparisons with published references may be used as an alternative to assess skeletal completeness but they are too general for a case-by-case routine analysis. The objective is to solve this issue by creating linear regression equations to estimate the total mass of a skeleton based on the mass of individual bones.Materials and MethodsTotal adult skeletal mass and individual mass of the clavicle, humerus, femur, patella, carpal, metacarpal, tarsal, and metatarsal bones were recorded in a sample of 60...

  9. Quantitative determinations and imaging in different structures of buried human bones from the XVIII-XIXth centuries by energy dispersive X-ray fluorescence - Postmortem evaluation

    Guimarães, D.; Dias, A. A.; Carvalho, M.; Carvalho, M. L.; Santos, J. P.; Henriques, F. R.; Curate, Francisco; Pessanha, S.
    In this work, a non-commercial triaxial geometry energy dispersive X-ray Fluorescence (EDXRF) setup and a benchtop mu-XRF system were used to identify postmortem contamination in buried bones. For two of the individuals, unusually high concentrations of Cu and Pb, but also Zn (in one individual) were observed. The pigments of the burial shroud coverings have been identified as the source of contamination.Accurate and precise quantitative results were obtained by nondestructive process using fundamental parameters method taking into account the matrix absorption effects.A total of 30 bones from 13 individuals, buried between the mid-XVlllth to early XIXth centuries, were analyzed to...

  10. A method for sex estimation using the proximal femur

    Curate, Francisco; Coelho, João; Gonçalves, David; Coelho, Catarina; Ferreira, Maria Teresa; Navega, David; Cunha, Eugénia
    The assessment of sex is crucial to the establishment of a biological profile of an unidentified skeletal individual. The best methods currently available for the sexual diagnosis of human skeletal remains generally rely on the presence of well-preserved pelvic bones, which is not always the case. Postcranial elements, including the femur, have been used to accurately estimate sex in skeletal remains from forensic and bioarcheological settings. In this study, we present an approach to estimate sex using two measurements (femoral neck width [FNW] and femoral neck axis length [FNAL]) of the proximal femur. FNW and FNAL were obtained in a...

  11. Family and the psychiatric reform

    Porto, Flávia Figueira; Rezende, Manuel Morgado; Gomes, Miria Benincasa
    This work discusses the experience of caring for a family member with a mental illness, including the concepts surrounding the subject and its handling in Brazil's recent psychiatric reform. As a strategy for analyzing data, and based on the theory of object relations developed by Winnicott (1975), the work is structured by means of two categories: the carer's concepts and experiences of mental illness and the burden experienced. The results of the research pointed to ambiguous feelings in the relationship with the family member suffering from the mental illness; a reverting to internment as the main course of action in...

  12. The Bom Santo Cave (Lisbon, Portugal): catchment, diet, and patterns of mobility of a Middle Neolithic population

    Carvalho, António Faustino; Alves-Cardoso, Francisca; Gonçalves, David; Granja, Raquel; Cardoso, João Luís; Dean, Rebecca M.; Francisco Gibaja, Juan; Masucci, Maria A.; Arroyo-Pardo, Eduardo; Fernández-Domínguez, Eva; Petchey, Fiona; Price, T. Douglas; Mateus, José Eduardo; Queiroz, Paula Fernanda; Callapez, Pedro; Pimenta, Carlos; Regala, Frederico T.
    The study of the Bom Santo Cave (central Portugal), a Neolithic cemetery, indicates a complex social, palaeoeconomic, and population scenario. With isotope, aDNA, and provenance, analyses of raw materials coupled with stylistic variability of material culture items and palaeogeographical data, light is shed on the territory and social organization of a population dated to 3800-3400 cal BC, i.e. the Middle Neolithic. Results indicate an itinerant farming, segmentary society, where exogamic practices were the norm. Its lifeway may be that of the earliest megalithic builders of the region, but further research is needed to correctly evaluate the degree of this community's...

  13. A method for estimating gestational age of fetal remains based on long bone lengths

    Carneiro, Cristiana; Curate, Francisco; Cunha, Eugénia
    The estimation of gestational age (GA) in fetal human remains is important in forensic settings, particularly to assess fetal viability, in addition to often being the only biological profile parameter that can be assessed with some accuracy for non-adults. The length of long bone diaphysis is one of the most frequently used methods for fetal age estimation. The main objective of this study was to present a simple and objective method for estimating GA based on the measurements of the diaphysis of the femur, tibia, fibula, humerus, ulna, and radius. Conventional least squares regression equations (classical and inverse calibration approaches)...

  14. Implicit sequence learning is preserved in dyslexic children

    Inácio, Filomena; Faísca, Luís; Forkstam, Christian; Araújo, Susana; Bramão, Inês; Reis, Alexandra; Petersson, Karl Magnus
    This study investigates the implicit sequence learning abilities of dyslexic children using an artificial grammar learning task with an extended exposure period. Twenty children with developmental dyslexia participated in the study and were matched with two control groups-one matched for age and other for reading skills. During 3 days, all participants performed an acquisition task, where they were exposed to colored geometrical forms sequences with an underlying grammatical structure. On the last day, after the acquisition task, participants were tested in a grammaticality classification task. Implicit sequence learning was present in dyslexic children, as well as in both control groups, and...

  15. Automatic generation of exercises on passive transformation in portuguese

    Baptista, Jorge; Lourenço, Sandra; Mamede, Nuno J.
    Technology plays a very important role in education and Intelligent Computer-Assisted Language Learning (iCALL) has emerged as a complementary or even alternative method to the conventional language teaching practices. The automatic generation (and correction) of language exercises based on real texts extracted from corpora constitutes a non-trivial challenge to iCALL tutorial systems, and may involve the use of sophisticated Natural Language Processing tools and large-scale linguistic resources. This paper presents the main issues related to the automatic generation of exercises on the Passive transformation, a commonly occurring type of exercises in language textbooks, but also a very complex topic of...

  16. Automated anonymization of text documents

    Dias, Francisco; Mamede, Nuno; Baptista, Jorge
    Sharing data in the form of text is important for a wide range of activities but it also raises a concern about privacy when sharing data that could be sensitive. Automated text anonymization is a solution for removing all the sensitive information from documents. However, this is a challenging task due to the unstructured form of textual data and the ambiguity of natural language. In this work, we present our implementation of an automated anonymization system, built in a modular structure, for documents written in Portuguese. Four different methods of anonymization are evaluated and compared. Two methods replace the sensitive...

  17. Sal e pesca no Algarve romano

    Bernardes, João Pedro; Cassandra, Gonçalves
    Os achados arqueológicos de um número alargado de tanques para salga de peixe (cetárias) nos sítios romanos do Sudoeste Peninsular Ibérico demonstram uma forte ligação das populações costeiras ao mar. Esse vínculo encontra-se atestado pela frequência de motivos marinhos e atividades piscatórias na iconografia dos mosaicos e moedas das zonas litorais hispânicas cujos recursos foram intensamente explorados e possibilitaram a rentabilidade e o desenvolvimento económico dessas regiões. Na Lusitania romana as principais zonas de concentração de fábricas de processamento de peixe foram o Algarve e os estuários do Tejo e do Sado. Os dados disponíveis evidenciam a existência de um aproveitamento das matérias-primas diretamente relacionadas com a localização das fábricas...

  18. Too little or too much? Parafoveal preview benefits and parafoveal load costs in dyslexic adults

    Silva, Susana; Faísca, Luís; Araújo, Susana; Casaca, Luis; Carvalho, Loide; Petersson, Karl Magnus; Reis, Alexandra
    Two different forms of parafoveal dysfunction have been hypothesized as core deficits of dyslexic individuals: reduced parafoveal preview benefits ("too little parafovea") and increased costs of parafoveal load ("too much parafovea"). We tested both hypotheses in a single eye-tracking experiment using a modified serial rapid automatized naming (RAN) task. Comparisons between dyslexic and non-dyslexic adults showed reduced parafoveal preview benefits in dyslexics, without increased costs of parafoveal load. Reduced parafoveal preview benefits were observed in a naming task, but not in a silent letter-finding task, indicating that the parafoveal dysfunction may be consequent to the overload with extracting phonological information...

  19. Visual naming deficits in dyslexia: An ERP investigation of different processing domains

    Araújo, Susana; Faísca, Luís; Reis, Alexandra; Frederico Marques, J.; Petersson, Karl Magnus
    Naming speed deficits are well documented in developmental dyslexia, expressed by slower naming times and more errors in response to familiar items. Here we used event-related potentials (ERPs) to examine at what processing level the deficits in dyslexia emerge during a discrete-naming task. Dyslexic and skilled adult control readers performed a primed object-naming task, in which the relationship between the prime and the target was manipulated along perceptual, semantic and phonological dimensions. A 3 x 2 design that crossed Relationship Type (Visual, Phonemic Onset, and Semantic) with Relatedness (Related and Unrelated) was used. An attenuated N/P190 - indexing early visual...

  20. Boca do Rio (Budens, Vila do Bispo): novos dados de uma villa piscícola romana

    Bernardes, João Pedro; Medeiros, Ismael
    O sítio da Boca do Rio é bem conhecido desde que o tsunami de 1755 colocou à vista, até hoje, as suas ruínas romanas. Cento e vinte anos depois iniciam-se um conjunto de campanhas arqueológicas, suscitadas, em grande parte, pela tentativa de resgatar da destruição pela ação marítima os bem conservados testemunhos da presença romana. Este artigo, apresentado nos Encontros de Arqueologia do Algarve de 2011, do qual nunca saíram atas, dá sobretudo conta de mais uma dessas campanhas com vista a salvar um mosaico do sítio, permitindo esta intervenção conhecer um pouco mais desta notável estação arqueológica e de propor uma interpretação do sítio no que...
