A PERCEPÇÃO DE SUPORTE SOCIAL NUMA AMOSTRA DE IMIGRANTES EM PORTUGAL

The principal objective of the present investigation is to study the impact of immigration in social support perception. The sample of immigrants is composed by 48 participants from countries such as Ukraine, Georgia, Moldavia, Russia, Brazil, China and Cabo-Verde. The average age is 34,67 years and the average time of residence in Portugal is 50,38 months. From participant, 21 are females and 27 are males. Perception of social support was assessed by SPE (Social Provisions Scale, Cutrona & Russel, 1990). The perception of social support was assessed before immigration, retrospectively, through an adaptation of SPE, and also after immigration. Results show that social support perception is significantly different before and after immigration, and is higher after immigration. Results show also, that the perception of social support is independent of the number of the time residence. However, for the Eastern population alone, no differences appear between social support perceptions before and after immigration. Key-words: Immigration; Social Support.
OpenType fonts in LuaTEX

As is well-known, LuaTEX can handle standard font formats, notably including OpenType. That’s a welcome development because modern font designs use those formats almost exclusively, and whatever the merits of METAFONT, for modern typographic software to stick to it would be suicidal. Lesser known perhaps is that, unlike X E TEX, which opened the way, LuaTEX is completely unable to load such a font if you don’t feed it a non-negligible amount of code beforehand. Otherwise it only understands your old TFMs (it actually embeds Type 1 fonts in PDF documents, a behavior inherited from PDFTEX, but only because a mapping exists between the TFM and Type 1 fonts; the latter can’t be read directly). The reason is not that LuaTEX isn’t so capable after all and you have to rely on some work-around; rather, LuaTEX is consistent with its philosophy (as I see it): it provides tools, not solutions. So you have to do most of the work to make it understand OpenType fonts, and that’s no simple work, but in the process you gain freedom. In this paper I’ll try to describe such code. I won’t give an entire implementation, and in many places I’ll just go with “This or that should be done”, because as already mentioned it would be extremely long (and tedious). ConTEXt’s fontloader, available for plain TEX and LTEX as luaotfload, is more than 10, 000 lines long, and my own code, which doesn’t even try to address non-Latin typography, is 2, 000 lines. In other words, I’ll give a map of the area to the reader, but nothing can replace the actual exploration. Also, this paper has limitations: first, all my examples will use the Latin alphabet, even though some features would have been better illustrated with other scripts; I apologize to users of other writing systems, but I thought it better not to pretend I was competent in them. This extends to maths, so OpenType maths aren’t covered at all; [2,7] should help the interested reader. The omission of maths is even more significant than for non-Latin writing
RANSAC for ( Quasi-) Degenerate data ( QDEGSAC ) Anonymous CVPR submission

106 107 CVPR #37 CVPR #37 Abstract The computation of relations from a number of potential matches is a major task in computer vision. Often RANSAC is employed for the robust computation of the relations such as the fundamental matrix. For (quasi-)degenerate data however it often fails to compute the correct relation. The computed relation is always consistent with the data but RANSAC does not verify that it is unique. The paper proposes a framework that estimates the correct relation with the same robustness as RANSAC even for (quasi-)degenerate data. The approach is based on a hierarchical RANSAC over the number of constraints provided by the data. In contrast to all previously presented algorithms for (quasi-)degenerate data our technique does not require problem specific tests or models to deal with degenerate configurations. Accordingly it can be applied for the estimation of any relation on any data and is not limited to a special type of relation as previous approaches. The results are equivalent to the results achieved by state of the art approaches that employ knowledge about degeneracies.

The present work analyzestheteenagers’video games use frequency as well as the places associated to that practice and likewise reveal the opinion people have about those games’possible and daily repercussions, essentially at a personal and social level. This study uses a quantitative method based on a data collection using an ad hoc questionnaire built on the predefined objectives. The study sample consisted of 124 students (62 women and 62 men) from a secondary school of the province of Pontevedra.
Knowledge Discovery for Query Formulation for Validation of a Bayesian Belief Network

This paper proposes machine learning techniques to discover knowledge in a dataset in the form of if-then rules for the purpose of formulating queries for validation of a Bayesian belief network model of the same data. Although do-main expertise is often available, the query formulation task is tedious and laborious, and hence automation of query formulation is desirable. In an effort to automate the query formulation process, a machine learning algorithm is lev-eraged to discover knowledge in the form of if-then rules in the data from which the Bayesian belief network model under validation was also induced. The set of if-then rules are processed and filtered through domain expertise to identify a subset that consists of “interesting” and “significant” rules. The subset of interesting and significant rules is formulated into corresponding queries to be posed, for validation purposes, to the Bayesian belief network induced from the same dataset. The promise of the proposed methodology was assessed through an empirical study performed on a real-life dataset, the National Crime Victimization Survey, which has over 250 attributes and well over 200,000 data points. The study demonstrated that the proposed approach is feasible and provides automation, in part, of the query formulation process for validation of a complex probabilistic model, which culminates in substantial savings for the need for human expert involvement and investment.
Uptake Patterns of Untreated Primary Gastrointestinal Extranodal Lymphomas on Initial Staging 18F-FDG PET/CT and Metabolic Tumor Parameters

Objective: Non-Hodgkin’s lymphomas arising from tissues other than primary lymphatic sites are classified as primary extranodal lymphomas (PEL). PELs of the gastrointestinal system (PGISL) originate from the lymphatic tissues within the gastrointestinal tract. The prognostic value of 18F-FDG PET/CT in lymphomas is high in terms of both overall survival (OS) and disease-free survival (DFS). Our aim was to investigate the uptake patterns and properties of low-grade and high-grade PGISL on primary staging 18F-FDG PET/CT, as well as the prognostic significance of metabolic tumor parameters in high grade PGISL. Methods: Thirty-nine patients with PGISL were enrolled in this retrospective cohort study between 2004-2015. Primary staging 18F-FDG PET/CT have been performed and quantitative parameters of SUVmax, SUVmean, metabolic tumor volume (MTV), total lesion glycolysis (TLG) have been calculated for all patients prior to treatment. Low-grade and high-grade PGISL were compared in terms of metabolic tumor parameters. Cox regression models were performed to determine factors that correlate with DFS in high-grade PGISL. Results: There were statistically significant differences between high-grade and low-grade PGISL in terms of SUVmax, SUVmean, MTV, TLG, recurrence, mortality, DFS and OS. None of the potential risk factors (sex, age, site, SUVmax, SUVmean, MTV, TLG) for recurrence and metastasis in high grade PGISL was identified as a risk factor on univariate and multivariate Cox regression analysis. Conclusion: Metabolic tumor parameters are not predictive markers in high-grade PGISL, especially in diffuse large B cell variant and primary gastric lymphoma. The first implications suggest they will not play a role in patient management.
MONITORING ANTIBIOTICS IN MILK-THE CHANGING WORLD OF TEST METHODS

For many years, the UK operated a national approach to the detection of antibiotics in milk, the Delvotest P (Gist-brocades BV, The Netherlands) being, initially, the only test listed in the Joint Committee Code of Practice for the Assessment of Milk Quality (the 'Blue Book'). Thus, the Delvotest P was accepted nationally for the examination of tanker milks and became known as the 'UK Industry Standard' test. In 1992, the LacTek ß-lactam test (Idexx Laboratories, USA) became the first 'rapid' test to be incorporated into the Blue Book but, since deregulation in 1994, several new rapid tests have appeared that differ significantly in sensitivity as well as in the range of substances detected. Although the newer tests are not yet listed in the Blue Book, their presence within the dairy industry, raises the question, "Are we now spoiled for choice? " and there is considerable debate over the advantages and limitations of different proprietary tests. To enable objective comparisons to be made, the International Dairy Federation has produced two guideline documents for the evaluation of tests that detect antibiotics in milk, the first of which has been adopted by ISO as an International Standard (1). In England & Wales, the Milk Quality Forum and the Dairy Industry Federation commissioned the Hannah Research Institute to assess independently the test manufacturers' claims. This work has formed the basis for revising the Blue Book list of tests and the final report of the Hannah work (2) has recently been issued (28 July). At the time of writing, however, the revised list of Blue Book 'acceptable' tests remains eagerly awaited.
Positive Youth Development Interventions Impacting the Sexual Health of Young Minority Adolescents: A Systematic Review

A systematic literature review was conducted to assess the utility of Positive Youth Development (PYD) concepts in promoting positive sexual health behaviors in young minority adolescents (n = 12 studies). Interventions reported significant associations between PYD-focused interventions and ever having sex, sexual partners in the last 30 days, using protection at the last sexual encounter, and decreased pregnancy rates. Outcomes were reviewed by age, gender, PYD constructs, cultural tailoring of interventions, and retention rates. Few interventions focused exclusively on young minority adolescents. PYD can be an effective tool in promoting sexual health in younger minority adolescents, but additional research is needed to determine beneficial strategies for this age group and timing of interventions. Recommendations for future studies include additional guidance on operationalization of PYD concepts, effective cultural tailoring methods, dosage of intervention components, and de-linking minority status from socioeconomic status (SES) and high-risk behaviors.
A Simple Model to Study Tau Pathology

Tau proteins play a role in the stabilization of microtubules, but in pathological conditions, tauopathies, tau is modified by phosphorylation and can aggregate into aberrant aggregates. These aggregates could be toxic to cells, and different cell models have been used to test for compounds that might prevent these tau modifications. Here, we have used a cell model involving the overexpression of human tau in human embryonic kidney 293 cells. In human embryonic kidney 293 cells expressing tau in a stable manner, we have been able to replicate the phosphorylation of intracellular tau. This intracellular tau increases its own level of phosphorylation and aggregates, likely due to the regulatory effect of some growth factors on specific tau kinases such as GSK3. In these conditions, a change in secreted tau was observed. Reversal of phosphorylation and aggregation of tau was found by the use of lithium, a GSK3 inhibitor. Thus, we propose this as a simple cell model to study tau pathology in nonneuronal cells due to their viability and ease to work with.
Direct Computation of Epipoles Using Two Pairs of Point-Line Correspondences

One of the most important geometric entities of the epipolar geometry is the epipole. Epipoles can be defined as the intersection of the baseline (the line joining the two camera centers) with each of the two image planes in a stereo rig. In order to compute the epipoles in a stereo rig, many of the algorithms in computer vision involve the computation of the fundamental matrix as an intermediate step. In this paper, however, a novel approach for direct computation of epipoles which eliminates the need for computation of the fundamental matrix is proposed. To achieve this goal, four pairs of correspondences (two point-line and two line-point correspondences) will suffice.
The Characteristics of Macroeconomic Shocks in the CFA Franc Zone

In this paper we fit a vector error correction model (VECM) in output and prices to data from 10 countries of the CFA Franc Zone. This model allows for various cross-country interactions in both the short run and the long run. The VECM parameters are used to estimate persistence profiles of different kinds, in order to identify the degree of homogeneity in the way in which the countries respond to macroeconomic shocks. In this way we can shed light on questions about the likely size of the costs incurred from these countries' membership of a monetary union. Copyright 2004, Oxford University Press.
40 nm Dual-port and two-port SRAMs for automotive MCU applications under the wide temperature range of −40 to 170°C with test screening against write disturb issues

A 2-read/write dual-port SRAM and 1-read/1-write two-port SRAM with stable operation at temperatures of -40 to 170°C are implemented in 40 nm embedded flash CMOS technology for automotive microcontroller applications. To reduce the leakage current and to ensure the read/write operating margin at over 125°C, a new 8T SRAM bitcell with the optimized process and sizing is proposed. A test circuit for screening disturb failures for dual-port and two-port SRAMs is also proposed. Designed and fabricated test chips showed that measured Vmin is achieved under 0.7 V with good distribution. Results show that the proposed test circuits can screen the disturb failures effectively.
Title of Article : Stable Oil Bodies Sheltered by a Unique Oleosin in Lily Pollen :

Stable oil bodies were purified from mature lily (Lilium longiflorum Thunb.) pollen. Integrity of pollen oil bodies was maintained via electronegative repulsion and steric hindrance possibly provided by their surface proteins. Immunodetection revealed that a major protein of 18 kDa was exclusively present in pollen oil bodies and massively accumulated in late stages of pollen maturation. According to mass spectrometric analyses, this oil-body protein possessed a trypic fragment of 13 residues matching to that of a theoretical rice oleosin. A complete cDNA fragment encoding this putative oleosin was obtained by PCR cloning with primers derived from its known 13-residue sequence. Sequence analysis as well as immunological non-cross recognition suggests that this pollen oleosin represents a distinct class in comparison with oleosins found in seed oil bodies and tapetum. In pollen cells observed under electron microscopy, oil bodies were presumably surrounded by tubular membrane structures, and encapsulated in the vacuoles after germination. It seems that pollen oil bodies are mobilized via a different route in contrast with the glyoxysomal mobilization of seed oil bodies after germination.
Blockade of current through single calcium channels by trivalent lanthanide cations. Effect of ionic radius on the rates of ion entry and exit

Currents flowing through single dihydropyridine-sensitive Ca2+ channels were recorded from cell-attached patches on C2 myotubes. In the presence of dihydropyridine agonist to prolong the duration of single-channel openings, adding micromolar concentrations of lanthanum (La), cerium (Ce), neodymium (Nd), gadolinium (Gd), dysprosium (Dy), or ytterbium (Yb) to patch electrodes containing 110 mM BaCl2 caused the unitary Ba2+ currents to fluctuate between fully open and shut states. The kinetics of channel blockade followed the predictions of a simple open channel block model in which the fluctuations of the single-channel current arose from the entry and exit of blocking ions from the pore. Entry rates for all the lanthanides tested were relatively insensitive to membrane potential, however, exit rates depended strongly on membrane potential increasing approximately e-fold per 23 mV with hyperpolarization. Individual lanthanide ions differed in both the absolute rates of ion entry and exit: entry rates decreased as cationic radius decreased; exit rates also decreased with cationic radius during the first part of the lanthanide series but then showed little change during the latter part of the series. Overall, the results support the idea that smaller ions enter the channel more slowly, presumably because they dehydrate more slowly; smaller ions also bind more tightly to a site within the channel pore, but lanthanide residence time within the channel approaches a maximum for the smaller cations with radii less than or equal to that of Ca2+.
Targeting Ion Channels: An Important Therapeutic Implication in Gastrointestinal Dysmotility in Patients With Spinal Cord Injury

Gastrointestinal (GI) dysmotility is a severe, and common complication in patients with spinal cord injury (SCI). Current therapeutic methods using acetylcholine analogs or laxative agents have unwanted side effects, besides often fail to have desired effect. Various ion channels such as ATP-sensitive potassium (KATP) channel, calcium ions (Ca2+)-activated potassium ions (K+) channels, voltage-sensitive Ca2+ channels and chloride ion (Cl−) channels are abundantly expressed in GI tissues, and play an important role in regulating GI motility. The release of neurotransmitters from the enteric nerve terminal, innervating GI interstitial cells of Cajal (ICC), and smooth muscle cells (SMC), causes inactivation of K+ and Cl− channels, increasing Ca2+ influx into cytoplasm, resulting in membrane depolarization and smooth muscle contraction. Thus, agents directly regulating ion channels activity either in ICC or in SMC may affect GI peristalsis and would be potential therapeutic target for the treatment of GI dysmotility with SCI.
Fundamental Components of the Gameplay Experience

This co-authored paper is based on research that originated in 2003 when our team started a series of extensive field studies into the character of gameplay experiences. Originally within the Children as the Actors of Game Cultures research project, our aim was to better understand why particularly young people enjoy playing games, while also asking their parents how they perceive gaming as playing partners or as close observers. Gradually our in-depth interviews started to reveal a complex picture of more general relevance, where personal experiences, social contexts and cultural practices all came together to frame gameplay within something we called game cultures. Culture was the keyword, since we were not interested in studying games and play experiences in isolation, but rather as part of the rich meaning-making practices of lived reality. In retrospect, our analysis of immersion has maintained much of its significance, and I must again thank my co-author Laura Ermi, who as a trained psychologist also was the main author during the construction of research instruments and in the analysis of our findings. I personally profited not only by learning immensely from Laura, but also from the interdisciplinary team work that later led us to study casual games and gamers, as well as social games played on Facebook and elsewhere. This was also a direction that best reveals the inevitable limitations of the present paper.
The Reluctance to Change a Way of Thinking

The theory of Radical Constructivism is restated with emphasis on its two basic principles: 1) that knowledge is built up through subjective activity, and 2) that the function of cognition is adaptive and focused on the organisation of the experiential world. The work of Piaget is used both to illuminate an innovation in constructivistic theory that was misinterpreted, and to provide a language for analysing such misinterpretations. The most frequent misinterpretations and objections to Radical Constructivism are outlined and refuted. These include the issues of solipsism, instrumentation, the relativity of problems and solutions, and the constructivist analysis of language and communication.
The Editor’s Note: Every teacher highly qualified

The focus on high-quality teaching, which was promoted in NCLB, should continue in the era of the Every Student Succeeds Act (ESSA). Federal legislation aside, states, local districts, and universities can take steps to ensure that high-quality teaching still occurs in U.S. classrooms. To begin, the U.S. should develop a system to identify students as early as middle school who have the potential to be teachers. In college, these students should do lots of practice teaching, always under the watchful eye of a master teacher. Every teacher would be required to become a National Board Certified Teacher before they are granted tenure. All teachers should work a full year. In sum, the U.S. should develop a system that does not promote stars but one that ensures every teacher is able to teach to his or her potential and that every teacher delivers the high-quality education that every child deserves.
Dynamics of Yeast Populations during Cider Fermentation in the Asturian Region of Spain

The influence of different cidermaking systems and apple mixtures on the dynamics of yeast populations in cider manufactured in Asturias (northern Spain) were studied. Results obtained in an experimental pilot plant were compared with those found in Asturian cider plants by using traditional techniques. Saccharomyces cerevisiae and Kloeckera apiculata were found in all cases.
Web unit mining: finding and classifying subgraphs of web pages

In web classification, most researchers assume that the objects to classify are individual web pages from one or more web sites. In practice, the assumption is too restrictive since a web page itself may not always correspond to a concept instance of some semantic concept (or category) given to the classification task. In this paper, we want to relax this assumption and allow a concept instance to be represented by a subgraph of web pages or a set of web pages. We identify several new issues to be addressed when the assumption is removed, and formulate the web unit mining problem. We also propose an iterative web unit mining (iWUM) method that first finds subgraphs of web pages using some knowledge about web site structure. From these web subgraphs, web units are constructed and classified into semantic concepts (or categories) in an iterative manner. Our experiments using the WebKB dataset showed that iWUM improves the overall classification performance and works very well on the more structured parts of a web site.
