Vários percursos diversas identificações : descendentes de migrantes cabo-verdianos no Bairro do Talude - Unhos

The research presented here aimed to analyze the processes of integration of Cape Verdeans immigrants descendants of living in the neighborhood of Talude, Town of Unhos, Municipality of Loures. To analyze the central object of research - the process of integration of descendants of migrants in the neighborhood of Talude we tried to answer the following questions, which reflect the objectives of the research:  What are the paths of socialization the descendants of immigrants: at the family, at school, in employment, in the neighborhood and in other activities?  What is the influence of gender relations in the processes of integration of descendants?  What are the perception the of immigrants descendants living in the neighborhood of Talude in relation to how they are viewed by residents of the Town residents in the neighborhood? And the people or society in general? And what influence these perceptions have in their process of integration? This study consists in two parts: the design of the survey, which is depicted on the reason for the choice of topic, the definition of the topic, research objectives, the method that was used in the course of investigation and the framing of the issue. In the second part, the analysis of data in different pathways: family, neighborhood, school, labor market, in other activities, the influence of gender and image(s). As a general conclusion we can say that there are several factors that contribute to the identification of immigrant descendants (there are no apparent factors that predominate) and the images they have of themselves and the Portuguese society in general are diverse.

Alfabetização de crianças caboverdianas em língua portuguesa como língua não materna : o ensino da leitura

abstract: Cape Verde is a country of bilingual characteristics, where coexist two languages: the mother tongue – the Creole of Cape Verde (CCV) or the Capeverdian Language (LCV) and the Non Maternal language – the Portuguese that is the official language and, therefore, the language used in the process of education and learning. This situation generates conflicts so much to linguistic level as to cultural level. The two languages presents some lexical resemblances, what drives, many times, to misconceptions and linguistics errors that complicate children in the learning, in particular, of reading that constitute the base for the learning of others knowledge. The learning of reading, in the Non Maternal language, requires a development of the oral language in Portuguese Language, which stimulates the reasoning of the child through playful exercises and cognitivists and construtivists approaches. In this way, the competences of phonological processing in the acquisition of the competences of reading are important for the discrimination of written text and favor the learning and the development of reading. The child, through the discovery, begins to elaborate concepts in the way to obtain a relation with the written language, by functional form. Adopting a methodology of case study and through questionnaires, direct observation and collect of documentary information, this dissertation presents and analyzes connected aspects to the literacy of capeverdian children in the beginning of the schooling and to the learning of reading as basic support for the learning of Non Maternal language. The subsidies collected by the study, presented in this dissertation will contribute for the education progress of reading and, also, for implement successfully the learning of reading of the students, developing to practical of reading and the expectations in uncover the multiplicity of the dimensions of experience in that domain and contribute for a relative comprehension of written and reading modes.

Interconnection among academic journal platforms: Multilateral versus bilateral interconnection

Electronic academic journal websites provide new services of text and/or datamining and linking, indispensable for e¢ cient allocation of attention among abun-dant sources of scienti?c information. Fully realizing the bene?t of these servicesrequires interconnection among websites. Motivated by CrossRef, a multilateralcitation linking backbone, this paper performs a comparison between multilateralinterconnection through an open platform and bilateral interconnection, and ?ndsthat publishers are fully interconnected in the former regime while they can be par-tially interconnected in the latter regime for exclusion or di¤erentiation motives.Surprisingly, if partial interconnection arises for di¤erentiation motive, exclusion ofsmall publisher(s) occurs more often under multilateral interconnection. We also?nd that in the case of multilateral interconnection, a for-pro?t platform inducesless exclusion than an open platform. Various other extensions are analyzed.

O texto literário na aula de português L2: uma proposta de didactização: Vida e morte de João Cabafume, de Gabriel Mariano

Na concepção deste trabalho, que tem como tema O texto literário na aula de Português L2 – Uma proposta de didactização: Vida e Morte de João Cabafume, de Gabriel Mariano, procurámos investigar e reflectir sobre a abordagem do texto literário no 3º ciclo do ensino secundário cabo-verdiano, especificamente na aula de Português L2, nas áreas de estudos Científica e Tecnológica e Económica e Social, do 11º ano de escolaridade, seguida da apresentação, a título de exemplo, de uma proposta de didactização do texto acima mencionado, na perspectiva da utilização do texto literário como material em que o uso estético da língua potencia a dimensão plural da significação. Para a consecução dos objectivos propostos, procurámos dar visibilidade, na perspectiva da leitura do texto literário, às orientações do programa, às potenciais práticas pedagógicas no ensino de narrativa literária, incluindo os métodos de ensino, os recursos utilizados pelos professores, a forma como os alunos encaram todo o processo de leitura do texto literário em que está envolvido. No entanto, para a concepção da proposta de didactização, procurámos cruzar propostas metodológicas de modelos de leitura e métodos de ensino do texto narrativo e de línguas defendidos por vários autores do campo da didáctica da literatura e das línguas, cujos princípios assentam em bases que valorizam a interacção entre o texto e o leitor. Partindo de um conto de Gabriel Mariano, escritor cabo-verdiano, Vida e Morte de João Cabafume, tentámos propor um roteiro de leitura adequada do texto narrativo, de forma a conduzir o aluno não só na leitura do contexto narrativo, como também na compreensão da dimensão plural da língua enquanto material estético, procurando desenvolver, fundamentalmente, as suas atitudes, os valores éticos e morais e, num âmbito complementar, as suas competências da escrita e da oralidade.

Use of 2D Sensitivity Encoding for Slow-Infusion Contrast-Enhanced Isotropic 3-T Whole-Heart Coronary MR Angiography.

OBJECTIVE. The purpose of this study was to improve the blood-pool signal-to-noise ratio (SNR) and blood-myocardium contrast-to-noise ratio (CNR) of slow-infusion 3-T whole-heart coronary MR angiography (MRA).SUBJECTS AND METHODS. In 2D sensitivity encoding (SENSE), the number of acquired k-space lines is reduced, allowing less radiofrequency excitation per cardiac cycle and a longer TR. The former can be exploited for signal enhancement with a higher radiofrequency excitation angle, and the latter leads to noise reduction due to lower data-sampling bandwidth. Both effects contribute to SNR gain in coronary MRA when spatial and temporal resolution and acquisition time remain identical. Numeric simulation was performed to select the optimal 2D SENSE pulse sequence parameters and predict the SNR gain. Eleven patients underwent conventional unenhanced and the proposed 2D SENSE contrast-enhanced coronary MRA acquisition. Blood-pool SNR, blood-myocardium CNR, visible vessel length, vessel sharpness, and number of side branches were evaluated.RESULTS. Consistent with the numeric simulation, using 2D SENSE in contrast-enhanced coronary MRA resulted in significant improvement in aortic blood-pool SNR (unenhanced vs contrast-enhanced, 37.5 +/- 14.7 vs 121.3 +/- 44.0; p < 0.05) and CNR (14.4 +/- 6.9 vs 101.5 +/- 40.8; p < 0.05) in the patient sample. A longer length of left anterior descending coronary artery was visualized, but vessel sharpness, coronary artery coverage, and image quality score were not improved with the proposed approach.CONCLUSION. In combination with contrast administration, 2D SENSE was found effective in improving SNR and CNR in 3-T whole-heart coronary MRA. Further investigation of cardiac motion compensation is necessary to exploit the SNR and CNR advantages and to achieve submillimeter spatial resolution.

The Impact of Instructions on Survey Translation : An Experimental Study

The experimental study described in this paper examined the impact of providing special instructions and supporting material to translators. Specifically, it addressed whether Spanish, Chinese, and French translators provided with explanatory text and guidelines were able to produce translations that were more faithful to the intended meaning of English source survey items, as well as that were more culturally appropriate and natural sounding compared to those of translators who received no such guidance. Study findings indicate that while the provision of special instructions and documentation to translators had a considerable impact on their translations, the direction of the impact (positive or negative) diff ered across the target languages, according to scale ratings of professional survey researchers who were native speakers of those languages.

Effects of aerobic fitness on oxygen uptake kinetics in heavy intensity swimming.

This study aimed to characterise both the [Formula: see text] kinetics within constant heavy-intensity swimming exercise, and to assess the relationships between [Formula: see text] kinetics and other parameters of aerobic fitness, in well-trained swimmers. On separate days, 21 male swimmers completed: (1) an incremental swimming test to determine their maximal oxygen uptake [Formula: see text], first ventilatory threshold (VT), and the velocity associated with [Formula: see text] [Formula: see text] and (2) two square-wave transitions from rest to heavy-intensity exercise, to determine their [Formula: see text] kinetics. All the tests involved breath-by-breath analysis of freestyle swimming using a swimming snorkel. [Formula: see text] kinetics was modelled with two exponential functions. The mean values for the incremental test were 56.0 ± 6.0 ml min(-1) kg(-1), 1.45 ± 0.08 m s(-1); and 42.1 ± 5.7 ml min(-1) kg(-1) for [Formula: see text], [Formula: see text] and VT, respectively. For the square-wave transition, the time constant of the primary phase (τ(p)) averaged 17.3 ± 5.4 s and the relevant slow component (A'(sc)) averaged 4.8 ± 2.9 ml min(-1) kg(-1) [representing 8.9% of the end-exercise [Formula: see text] (%A'(sc))]. τ(p) was correlated with [Formula: see text] (r = -0.55, P = 0.01), but not with either [Formula: see text] (r = 0.05, ns) or VT (r = 0.14, ns). The %A'(sc) did not correlate with either [Formula: see text] (r = -0.14, ns) or [Formula: see text] (r = 0.06, ns), but was inversely related with VT (r = -0.61, P < 0.01). This study was the first to describe the [Formula: see text] kinetics in heavy-intensity swimming using specific swimming exercise and appropriate methods. As has been demonstrated in cycling, faster [Formula: see text] kinetics allow higher aerobic power outputs to be attained. The slow component seems to be reduced in swimmers with higher ventilatory thresholds.

Performance comparison of two commercial BGO-based PET/CT scanners using NEMA NU 2-2001.

Combined positron emission tomography and computed tomography (PET/CT) scanners play a major role in medicine for in vivo imaging in an increasing number of diseases in oncology, cardiology, neurology, and psychiatry. With the advent of short-lived radioisotopes other than 18F and newer scanners, there is a need to optimize radioisotope activity and acquisition protocols, as well as to compare scanner performances on an objective basis. The Discovery-LS (D-LS) was among the first clinical PET/CT scanners to be developed and has been extensively characterized with older National Electrical Manufacturer Association (NEMA) NU 2-1994 standards. At the time of publication of the latest version of the standards (NU 2-2001) that have been adapted for whole-body imaging under clinical conditions, more recent models from the same manufacturer, i.e., Discovery-ST (D-ST) and Discovery-STE (D-STE), were commercially available. We report on the full characterization both in the two- and three-dimensional acquisition mode of the D-LS according to latest NEMA NU 2-2001 standards (spatial resolution, sensitivity, count rate performance, accuracy of count losses, and random coincidence correction and image quality), as well as a detailed comparison with the newer D-ST widely used and whose characteristics are already published.

Acute supra-therapeutic oral terbutaline administration has no ergogenic effect in non-asthmatic athletes.

This study aimed to investigate the effects on a possible improvement in aerobic and anaerobic performance of oral terbutaline (TER) at a supra-therapeutic dose in 7 healthy competitive male athletes. On day 1, ventilatory threshold, maximum oxygen uptake [Formula: see text] and corresponding power output were measured and used to determine the exercise load on days 2 and 3. On days 2 and 3, 8 mg of TER or placebo were orally administered in a double-blind process to athletes who rested for 3 h, and then performed a battery of tests including a force-velocity exercise test, running sprint and a maximal endurance cycling test at Δ50 % (50 % between VT and [Formula: see text]). Lactatemia, anaerobic parameters and endurance performance ([Formula: see text] and time until exhaustion) were raised during the corresponding tests. We found that TER administration did not improve any of the parameters of aerobic performance (p > 0.05). In addition, no change in [Formula: see text] kinetic parameters was found with TER compared to placebo (p > 0.05). Moreover, no enhancement of the force-velocity relationship was observed during sprint exercises after TER intake (p > 0.05) and, on the contrary, maximal strength decreased significantly after TER intake (p < 0.05) but maximal power remained unchanged (p > 0.05). In conclusion, oral acute administration of TER at a supra-therapeutic dose seems to be without any relevant ergogenic effect on anaerobic and aerobic performances in healthy athletes. However, all participants experienced adverse side effects such as tremors.

Tc-99m-MAA SPECT-derived tumor-to-normal liver ratios for partition model dosimetry in selective internal radiation therapy (SIRT)

Aim: When planning SIRT using 90Y microspheres, the partition model is used to refine the activity calculated by the body surface area (BSA) method to potentially improve the safety and efficacy of treatment. For this partition model dosimetry, accurate determination of mean tumor-to-normal liver ratio (TNR) is critical since it directly impacts absorbed dose estimates. This work aimed at developing and assessing a reliable methodology for the calculation of 99mTc-MAA SPECT/CT-derived TNR ratios based on phantom studies. Materials and methods: IQ NEMA (6 hot spheres) and Kyoto liver phantoms with different hot/background activity concentration ratios were imaged on a SPECT/CT (GE Infinia Hawkeye 4). For each reconstruction with the IQ phantom, TNR quantification was assessed in terms of relative recovery coefficients (RC) and image noise was evaluated in terms of coefficient of variation (COV) in the filled background. RCs were compared using OSEM with Hann, Butterworth and Gaussian filters, as well as FBP reconstruction algorithms. Regarding OSEM, RCs were assessed by varying different parameters independently, such as the number of iterations (i) and subsets (s) and the cut-off frequency of the filter (fc). The influence of the attenuation and diffusion corrections was also investigated. Furthermore, both 2D-ROIs and 3D-VOIs contouring were compared. For this purpose, dedicated Matlab© routines were developed in-house for automatic 2D-ROI/3D-VOI determination to reduce intra-user and intra-slice variability. Best reconstruction parameters and RCs obtained with the IQ phantom were used to recover corrected TNR in case of the Kyoto phantom for arbitrary hot-lesion size. In addition, we computed TNR volume histograms to better assess uptake heterogeneityResults: The highest RCs were obtained with OSEM (i=2, s=10) coupled with the Butterworth filter (fc=0.8). Indeed, we observed a global 20% RC improvement over other OSEM settings and a 50% increase as compared to the best FBP reconstruction. In any case, both attenuation and diffusion corrections must be applied, thus improving RC while preserving good image noise (COV<10%). Both 2D-ROI and 3D-VOI analysis lead to similar results. Nevertheless, we recommend using 3D-VOI since tumor uptake regions are intrinsically 3D. RC-corrected TNR values lie within 17% around the true value, substantially improving the evaluation of small volume (<15 mL) regions. Conclusions: This study reports the multi-parameter optimization of 99mTc MAA SPECT/CT images reconstruction in planning 90Y dosimetry for SIRT. In phantoms, accurate quantification of TNR was obtained using OSEM coupled with Butterworth and RC correction.

Mathematics in Catalonia: 1996-2002

The aim of this article is to present the main conclusions of the Report on research in Catalonia for the area of mathematics**. The report was prepared by Joaquim Bruna, Marta Sanz, Joan de Solà-Morales and the author of this text, and published by the Institute for Catalan Studies in 1998. In the report, scientific activity in the area of mathematics was measured essentially by examining two parameters: papers published in specialised journals and doctoral theses read. It should be recognised that a considerable amount of activity in the field of mathematics consists of applying existing knowledge to the resolution of practical technological problems that arise in particular companies. This kind of scientific activity was not measured in any way in the report due to the difficulty of obtaining objective data. This article is divided into the following sections: human resources, scientific production, funding, research publications, research centres, and conclusions.
