A Theoretical and Experimental Study for Screening Inhibitors for Styrene Polymerization
Authors: Darvishi Ali , Rahimpour Mohammad Reza , Raeissi Sona
Published: October 2019

Styrene is one of the most important monomers utilized in the synthesis of various polymers. Nevertheless, during distillation, storage, and transportation of ST, undesired polymer (i.e., UP) formation can take place. Thus, the control of undesired polymerization of styrene is a challenging issue facing industry. To tackle the mentioned issue, the antipolymer and antioxidant activity of stable nitroxide radicals (i.e., SNRs) and phenolics in styrene polymerization were studied by density functional theory (DFT) calculation and experimental approach. The electrophilicity index and growth percentage have been determined by DFT calculation and experimental approach, respectively. It is depicted that 2,6-di-tert-butyl-4-methoxyphenol (DTBMP) and 2,6-di-tert-butyl-4-methylphenol (BHT) from phenolics, and 4-hydroxy-2,2,6,6-tetramethyl piperidine 1-Oxyl (4-hydroxy-TEMPO) and 4-oxo-2,2,6,6-tetramethylpiperidine 1-Oxyl (4-oxo-TEMPO) from stable nitroxide radicals were the most effective inhibitors. Also, the growth percentage of DTMBP, BHT, 4-hydroxy-TEMPO, and 4-oxo-TEMPO after 4 h were 16.40, 42.50, 24.85, and 46.8, respectively. In addition, the conversion percentage of DTMBP, BHT, 4-hydroxy-TEMPO, and 4-oxo-TEMPO after 4 h were obtained to be 0.048, 0.111, 0.065, and 0.134, respectively. Furthermore, the synergistic effect of these inhibitors was investigated experimentally, indicating that DTMBP/4-hydroxy-TEMPO exerted the best synergistic effects on the inhibition of polymerization. The optimum inhibition effect was observed at the blend of 4-hydroxy-TEMPO (25 wt.%) and DTMBP (75 wt.%) corresponding to 6.8% polymer growth after 4 h.
Multi-Agent Consensus Algorithm-Based Optimal Power Dispatch for Islanded Multi-Microgrids
Authors: Zhai Xingli , Wang Ning
Published: October 2019

Islanded multi-microgrids formed by interconnections of microgrids will be conducive to the improvement of system economic efficiency and supply reliability. Due to the lack of support from a main grid, the requirement of real-time power balance of the islanded multi-microgrid is relatively high. In order to solve real-time dispatch problems in an island multi-microgrid system, a real-time cooperative power dispatch framework is proposed by using the multi-agent consensus algorithm. On this basis, a regulation cost model for the microgrid is developed. Then a consensus algorithm of power dispatch is designed by selecting the regulation cost of each microgrid as the consensus variable to make all microgrids share the power unbalance, thus reducing the total regulation cost. Simulation results show that the proposed consensus algorithm can effectively solve the real-time power dispatch problem for islanded multi-microgrids.
Flexible Flow Shop Scheduling Method with Public Buffer
Authors: Han Zhonghua , Han Chao , Lin Shuo , Dong Xiaoting , Shi Haibo
Published: October 2019

Actual manufacturing enterprises usually solve the production blockage problem by increasing the public buffer. However, the increase of the public buffer makes the flexible flow shop scheduling rather challenging. In order to solve the flexible flow shop scheduling problem with public buffer (FFSP–PB), this study proposes a novel method combining the simulated annealing algorithm-based Hopfield neural network algorithm (SAA–HNN) and local scheduling rules. The SAA–HNN algorithm is used as the global optimization method, and constructs the energy function of FFSP–PB to apply its asymptotically stable characteristic. Due to the limitations, such as small search range and high probability of falling into local extremum, this algorithm introduces the simulated annealing algorithm idea such that the algorithm is able to accept poor fitness solution and further expand its search scope during asymptotic convergence. In the process of local scheduling, considering the transferring time of workpieces moving into and out of public buffer and the manufacturing state of workpieces in the production process, this study designed serval local scheduling rules to control the moving process of the workpieces between the public buffer and the limited buffer between the stages. These local scheduling rules can also be used to reduce the production blockage and improve the efficiency of the workpiece transfer. Evaluated by the groups of simulation schemes with the actual production data of one bus manufacturing enterprise, the proposed method outperforms other methods in terms of searching efficiency and optimization target.
Can We Rely on Self-Assessments of Sense of Coherence? The Effects of Socially Desirable Responding on the Orientation to Life Questionnaire (OLQ) Responses
Authors: Lajunen Timo , Gaygısız Esma
Published: October 2019

A large number of studies in health psychology have shown that sense of coherence (SOC) is an essential factor in wellbeing and health. SOC is most commonly measured with the Antonovsky’s Orientation to Life Questionnaire (OLQ), which has been so far translated into at least 48 languages. Despite the vast popularity of the OLQ, the relationships between OLQ and socially desirable responding (impression management and self-deception) have not been studied. The purpose of the present study was to investigate the correlations between social desirability and Antonovsky’s OLQ. Method: The first sample consisted of 423 students who completed the 13-item OLQ and the Eysenck Personality Questionnaire (EPQ), including the Lie scale. Also, the Balanced Inventory for Desirable Responding by Paulhus was administered together with the OLQ to 202 students. Results: SOC correlated positively with measures of social desirability among men but not among women. Hence, sex moderated the relationship between socially desirable responding and sense of coherence. Conclusions: Socially desirable responding and, especially, self-deception are positively related to high scores in SOC among men but not among women. The OLQ as a measure of sense of coherence can be used among women without worrying about the bias caused by socially desirable responding. When using the OLQ among men, the strong relationship between self-deception and sense of coherence should be taken into account.

Published: October 2019

This paper discusses and explores the different effects of contractual forms on the satisfaction with public transport (PT) at different urban scales. Using public transport systems in 12cities in China as the focus (four large-I-sized cities, four large-II-sized cities, and four medium-sized cities), a measurement model of the passenger satisfaction index (PSI) is constructed and estimated on the basic of the adjusted European Customer Satisfaction Index (ECSI) and Partial least square-structural equation model (PLS-SEM), respectively. Then, a two-stage truncation regression bootstrap model is proposed to assess the different effects between them. The major findings of this study are summarized as follows: (1) different effects of contractual forms on PT satisfaction in large- and medium-sized cities are confirmed. (2) In large-I-sized cities and lager II sized cities, operators supervised by management contracts incite higher PT satisfaction levels than those supervised by gross and net cost contracts. (3) In medium-sized cities, operators supervised by gross cost contracts provide incentives to be the satisfaction compared to those of management and net cost contracts. According to different urban scales, different and appropriate contractual forms and supervision mechanisms should be chosen to regulate public transport services.

Published: October 2019

Rural and urban areas are mainly connected by public transport in China. The characteristics of the trips of local residents in rural and urban areas are different; therefore, the demand for public transport information services is different. Based on the revealed data, a structural equation model is applied to examine the critical factors affecting the behavior of urban and rural residents in choosing public transport in the Beidaihe District, Qinhuangdao City, China. The effect of information service factors on public transport behavior of urban and rural residents is obtained. The influence level of public transport information service on public transport behavior of urban and rural residents before and during travel is discussed. This study provides valuable insights to improving public transport services between urban and rural areas of China, which can attract more residents to use public transport and promotes sustainable development between urban and rural areas.
A Sparsity-Aware Variable Kernel Width Proportionate Affine Projection Algorithm for Identifying Sparse Systems
Authors: Jiang Zhengxiong , Li Yingsong , Huang Xinqi , Jin Zhan
Published: October 2019

A sparsity-aware variable kernel width proportionate affine projection (AP) algorithm is devised for identifying sparse system in impulsive noise environments. For the devised algorithm, the symmetry maximum correntropy criterion (MCC) is employed to develop a new cost function for improving the PAP algorithm, then the variable kernel width and the l p -norm-like constraint are incorporated into the cost-function, which is named as l p -norm variable kernel width proportionate affine projection (LP-VPAP) algorithm. The devised LP-VPAP algorithm is investigated and verified under impulsive interference environments. Experimental results show that the LP-VPAP gets a faster convergence and provides a lower steady-state performance compared with AP, zero-attracting AP (ZA-AP), reweighted ZA-AP (RZA-AP), proportionate AP (PAP), MCC, variable kernel width MCC (VKW-MCC), and proportionate AP MCC (PAPMCC) algorithms.
Greedy Method for Boarding a Partially Occupied Airplane Using Apron Buses

Published: October 2019

This paper investigates the time to complete the boarding of a partially occupied two-door airplane when its passengers are transported from the airport terminal to the airplane using two apron buses. We propose a greedy method that assigns each passenger to a particular apron bus based on the passengers’ airplane seat assignments. This greedy approach exploits the airplane’s symmetry by providing essentially the same method for those boarding through the front door of the airplane as those boarding through the rear door of the airplane. The symmetrical properties of window, middle, and aisle seats of each row/side are considered in the proposed method as well. Computer simulation results indicate that, when using the greedy method, the boarding time can be reduced by up to 8.33% compared to the boarding time resulting from the best known practices in the literature, and with up to a 43.72% improvement in boarding time when compared to the boarding method commonly used in many airports. Furthermore, experimental results confirm our hypothesis that when the capacity of the apron buses exceeds the number of passengers to be transported to the airplane, the most time-efficient results of the proposed greedy method occur when an equal number of passengers are assigned to each of the two apron buses.
Control Limits for an Adaptive Self-Starting Distribution-Free CUSUM Based on Sequential Ranks
Authors: Lang Michael
Published: October 2019

Since their introduction in 1954, cumulative sum (CUSUM) control charts have seen a widespread use beyond the conventional realm of statistical process control (SPC). While off-the-shelf implementations aimed at practitioners are available, their successful use is often hampered by inherent limitations which make them not easily reconcilable with real-world scenarios. Challenges commonly arise regarding a lack of robustness due to underlying parametric assumptions or requiring the availability of large representative training datasets. We evaluate an adaptive distribution-free CUSUM based on sequential ranks which is self-starting and provide detailed pseudo-code of a simple, yet effective calibration algorithm. The main contribution of this paper is in providing a set of ready-to-use tables of control limits suitable to a wide variety of applications where a departure from the underlying sampling distribution to a stochastically larger distribution is of interest. Performance of the proposed tabularized control limits is assessed and compared to competing approaches through extensive simulation experiments. The proposed control limits are shown to yield significantly increased agility (reduced detection delay) while maintaining good overall robustness.

Published: October 2019

Since 1998, a monitoring program is periodically performed to assess the environmental and human health impact of air chemicals potentially emitted by a hazardous waste incinerator (HWI) located in Constantí (Catalonia, Spain). In 2017, samples of hair were collected from 94 schoolchildren (aged 10–13 years) living nearby and the levels of 11 trace elements (As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sn, Tl and V) were determined. The concentrations showed the following descending order: Pb > Hg > Ni > Sn > Mn > Cr. In turn, As, Be and Tl were not detected, while Cd and V were found only in a few samples. Some metal levels were significantly, positively correlated. Some significant differences were also noticed according to the gender and the specific zone of residence. Finally, the levels of trace elements showed fluctuations through time. Cr and Pb showed a significant decrease in comparison to the concentrations obtained in the baseline study (1998). According to the current results, metal emissions from the HWI are not relevant in terms of human health impact since their levels were similar and even lower than those reported in other contaminated areas.

The National Immunization Program (NIP) on Bonaire, St. Eustatius and Saba (i.e., Caribbean Netherlands (CN)) includes the measles-mumps-rubella (MMR) vaccine since 1988/89. Seroepidemiological data is an important tool to evaluate the NIP, hence a cross-sectional representative population-based serosurveillance study was conducted for the first time in CN in mid-2017. Participants (n = 1829, aged 0–90 years) donated a blood sample and completed a health-related questionnaire. MMR-specific IgG antibodies were determined using a bead-based multiplex immunoassay and risk factors were analyzed using logistic regression models. Overall seroprevalence was high for measles (94%), but lower for mumps and rubella (both 85%). In NIP eligibles, including women of childbearing age, rubella seroprevalence (88%) exceeded the threshold for protection (85%); however, for measles (89%) this protective level (95%) was not met. MMR seropositivity was lowest in children who became CN resident at 11–17 years of age (especially for measles (72%)), mostly originating from Latin America and other non-Western countries. Interestingly, rubella seroprevalence was lowest in non-NIP eligible adults from Dutch overseas territories and Suriname (75%). Taken together, MMR immunity is generally good in CN, nonetheless some risk groups were identified. Additionally, we found evidence for a unique island epidemiology. In light of recent regional measles outbreaks, disease monitoring remains of utmost importance.
La ferrisicklérite des pegmatites de Sidi Bou Othmane (Jebilet, Maroc) et le groupe des minéraux à structure de triphylite

Published: October 2019

La présence de gros nodules de ferrisicklérite, souvent monocristallins, d'une pureté exceptionnelle, dans les filons de pegmatites de Sidi Bou Othmane (Jebilet), a incité à entreprendre une étude détaillée de cette espèce minérale peu connue et à examiner l'ensemble du groupe de la triphylite. Orthorhombique Pmnb ; sa structure a été étudiée simultanément par A. Alberti. Principales raies du diagramme de poudre : 5,01 (70), 4,33 (40), 3,82 (20), 3,49 (30), 2,96 (100), 2,49 (35). Deux clivages : (010) parfait, (100) bon. Très fortement colorée mais peu pléochroïque : ng = 1,820 sur b, jaune d'or ; nm = 1,805 sur a ; nv = 1,790 sur c, jaune orangé ; 2 V = — 85°. Les pouvoirs réflecteurs et les caractéristiques chromatiques ont été mesurés. Deux analyses chimiques sont données et interprétées, l'une d'une ferrisicklérite très pure, l'autre d'une ferrisicklérite partiellement altérée en hétérosite. Dans la formule schématique M (1) M (2) PO₄, les M (2) sont entièrement occupés par Fe⁺⁺⁺, Mn⁺⁺, (Mg) et (Ca), Mn restant bivalent tandis que Fe est entièrement trivalent ; les M (1) ne sont occupés qu'à 43,3 % par Li⁺ et par des traces de Na⁺ et (Ca⁺⁺) ; PO₄ est un peu remplacé par des H₄O₄. Des courbes d'analyses thermiques sont données et interprétées. Le groupe des minéraux à structure de triphylite est envisagé dans son ensemble du point de vue des compositions chimiques et des phénomènes d'altération ; la théorie classique du passage continu de la triphylite à la ferrisicklérite et enfin à l'hétérosite est discutée, et paraît devoir être aménagée pour mieux rendre compte de la réalité. Pour expliquer la différence irréductible entre les densités mesurée (3,41) et calculée (3,53), et l'absence d'ordre entre Fe⁺⁺⁺ et Mn⁺⁺ en position M (2), on est amené à admettre un dépôt initial du minéral sous forme de triphylite et sa transformation en ferrisicklérite par une action hydrothermale hypogène antérieure à une métasomatose sodique ayant produit de l'alluaudite.

Salaires, prestations sociales et pouvoir d'achat de 1964 )à 1966
Authors: Perrot Marguerite
Published: October 2019

La documentation sur les salaires et les prestations sociales pour la période 1938-1963 avait été rassemblée à l'occasion d'une publication précédente. L'étude ci-dessous constitue une mise à jour pour les années 1964, 1965 et 1966 des principaux tableaux qui avaient été alors établis. On étudiera successivement les rémunérations dans les entreprises industrielles et commerciales, les rémunérations de la fonction publique, les compléments sociaux des salaires (prestations familiales et allocations de chômage). Après l'étude des salaires nominaux, on tentera de mesurer l'évolution du pouvoir d'achat pour les années récentes avec référence aux années 1949, 1956 et 1962.

Les salaires horaires ont progressé en trois ans de 20 % environ (soit 11 à 12 % pour le pouvoir d'achat). La croissance des salaires mensuels ou annuels est plus difficile à apprécier caries données statistiques ne sont pas disponibles pour 1966, ni partiellement pour 1965.
Premiers résultats d'une enquête permanente sur la consommation alimentaire des français

Published: October 2019

Quelles sont les caractéristiques du comportement des Français dans le domaine des consommations alimentaires ? L'enquête réalisée par l'I.N.S.E.E., dont les premiers résultats sont publiés dans le présent compte rendu permet de fournir une réponse précise et détaillée à la question ainsi posée.

L'enquête a été effectuée tout au long de l'année 1965. Destinée à être permanente, elle s'est poursuivie depuis ; les résultats relatifs à l'année 1966 seront publiés au cours de l'année 1967 et il est prévu de réaliser prochainement une exploitation rapide des enquêtes suivantes au niveau du trimestre.

Ainsi disposera-t-on d'un instrument précieux pour suivre l'évolution temporelle des consommations alimentaires, permettant d'étudier l'influence des facteurs dynamiques qui les conditionnent : progression des niveaux de vie, variations de prix, modifications dans les goûts et les habitudes des consommateurs des différentes catégories de la population.

L'étude des structures de la consommation alimentaire et de leur évolution sera conduite, non seulement pour l'ensemble de la population mais pour les diverses catégories qui la composent ; il deviendra ainsi possible de comparer, en niveau et évolution, la situation de ces diverses catégories : agriculteurs, familles nombreuses, salariés urbains modestes...

Dans ce premier compte rendu, qui doit être suivi d'analyses plus fines et détaillées, le plan que nous avons adopté est le suivant : nous présentons, dans une première partie, l'enquête. Puis dans un second chapitre, nous en indiquerons les principales caractéristiques et les objectifs. Les résultats sont enfin analysés assez brièvement dans la troisième partie, où nous nous sommes bornés à présenter les principales caractéristiques des comportements alimentaires des ménages.

Les détails relatifs à la méthodologie de l'enquête ont été reportés en annexe ainsi que certains tableaux, très détaillés, donnant pour différentes catégories de ménages définies en fonction de la catégorie socio-professionnelle du chef de ménage, de la région et du type d'habitat les consommations moyennes par personne exprimées à la fois en valeur et en quantité, ainsi que la répartition des achats suivant la catégorie d'habitat et le type de point de vente.
Note rapide sur l'évolution récente de la fécondité française
Authors: Calot Gérard , Hémery Solange
Published: October 2019

Dans la livraison précédente d'Études et Conjoncture (n° 1, janvier 1967), on a présenté la situation démographique française de l'année 1965, telle qu'elle résulte de l'exploitation statistique des documents de l'état civil. Par ailleurs, dans le Bulletin mensuel de statistique de janvier 1967, on a évalué le bilan démographique de l'année 1966 sur la base du décompte global des documents de l'état civil relatifs aux trois premiers trimestres.

Depuis la publication de ces résultats, la Division de Démographie générale de l'I.N.S.E.E. a entrepris différentes analyses complémentaires de l'évolution récente de la fécondité et de la nuptialité. Bien que ces travaux ne soient pas encore terminés, il a semblé utile d'en présenter dès maintenant deux résultats essentiels : la fécondité générale, qui connaissait une évolution régulière depuis une dizaine d'années (augmentation de la fécondité jusqu'à 30 ans, réduction au delà de 30 ans), a marqué une diminution significative en 1965 dont l'ampleur est de l'ordre de 3 à 4 % en moyenne.

Cette diminution de la fécondité générale est la résultante de deux réductions simultanées dont les effets se sont ajoutés : une réduction de la nuptialité féminine apparue en 1964 et confirmée en 1965, une réduction de la fécondité légitime en 1965. En résumé, les femmes se sont mariées moins nombreuses en 1964 et 1965 que les années précédentes ; en outre, celles qui étaient mariées en 1965 ont eu moins d'enfants, à âge égal, que les générations précédentes. S'ils étaient confirmés par l'analyse détaillée des résultats de l'année 1966 (qui ne seront disponibles qu'au deuxième semestre tie cette année), ces deux phénomènes concomitants pourraient marquer un tournant sérieux dans l'évolution du dynamisme démographique français. Rappelons à ce sujet que ces dernières années près d'un tiers de l'accroissement de la population française provenait de l'excédent des migrations avec l'étranger.

Il convient toutefois de noter qu'une baisse simultanée de la nuptialité et de la fécondité (la nuptialité a baissé en 1964, la fécondité a baissé en 1965, ce qui indique une diminution des conceptions en 1964) peut correspondre à une réaction collective passagère à certains phénomènes économiques ou à certains événements internationaux jugés à tort ou à raison comme inquiétants. En ce qui concerne la fécondité, ont pourrait penser que les discussions touchant à la planification de la famille ont eu quelques répercussions sur la psychologie collective des couples. Mais il ne faut pas perdre de vue que la contraception existe en France depuis le XVIIIe siècle : si on parle de plus en plus ouvertement des techniques contraceptives, les Français n'en ont pas attendu les derniers perfectionnements pour limiter la taille de leur famille.

On pourra enfin observer que la baisse de la natalité a affecté simultanément la quasi totalité des pays occidentaux en 1965. Inférieure à 5 % en Europe, elle a atteint 7,6 % aux États-Unis.
Méthodologie de l'enquête annuelle sur la répartition du territoire (enquête «contrôle de surface»)
Authors: Hulin M. , Delorme P.
Published: October 2019

La connaissance des superficies consacrées chaque année aux différentes cultures est un élément de base de la statistique agricole annuelle. Ces superficies sont appréciées à partir d'informations d'origines diverses : enquêtes spécifiques, cadastre viticole, inventaire forestier , etc. Il en résulte que les superficies de certaines catégories de territoire sont connues avec une bonne précision tandis que d'autres sont très mal connues.

L'enquête «contrôle de surface » est destinée à fournir en une seule opération des estimations de toutes les catégories de territoire de manière objective, c'est-à-dire par observation directe du terrain. En outre cette enquête fournit un cadre de dépouillement qui permet d'intégrer dans les estimations, grâce au tableau des assolements, des informations exogènes portant sur certaines catégories de territoire.
Le prix des terres agricoles en 1966
Authors: Greiner Pierre
Published: October 2019

Bien qu'ayant une valeur statistique limitée, l'enquête sur le prix des terres agricoles apporte chaque année un certain nombre de précisions sur l'évolution moyenne de la valeur des terres et les tendances générales du marché foncier ainsi que sur les aspects régionaux de ces phénomènes.

Les résultats pour 1966 confirment la tendance enregistrée l'an dernier à une pause dans le fort mouvement de hausse qui caractérisait le marché les années précédentes. Le taux moyen annuel d'augmentation du prix des terres se situe pour 1965 et 1966 aux environs de 8 %.

La hausse est un peu plus faible pour les prairies naturelles que pour les terres labourables, en général moins chères mais dont le prix tend depuis plusieurs années à s'aligner sur celui des prairies.

C'est la demande purement agricole, liée au nécessaire agrandissement des exploitations agricoles qui semble avoir été en 1966 l'élément le plus actif du marché et l'un des facteurs d'une hausse qui reste appréciable malgré le ralentissement constaté.

Cette hausse pourrait constituer un obstacle non négligeable à la politique de restructuration agricole actuellement poursuivie par les pouvoirs publics.
EFFICACY OF COLD POLYPECTOMY TECHNIQUES FOR SMALL POLYP (< 1CM) IN THE COLORECTUM

Published: October 2019

Background/Aim: Colonoscopic polypectomy is a very important intervention for the prevention of colorectal cancer progression. Whereas various techniques are used for the removal of polyps, hot polypectomy with electrocautery is still a standard technique. However, this technique has been associated with an increased risk of electrocautery-related complications, including bleeding or perforation. To reduce these complications, recent studies have found a polypectomy technique without electrocautery, so-called cold polypectomy. This new technique shows more efficacious in diminutive/small polyps. This study aims to evaluate the complete retrieval rate and the complications of cold polypectomy technique.

Patients/Methods: Prospectively study, 103 diminutive/small (< 1cm) polyps (53 patients) were removed by cold polypectomy technique from 11/2016 to 11/2017.

Results: the complete retrieval rate was 97.1%. The immediate bleeding rate was 1.9%. No delayed bleeding and perforation occurred in any 103 polyps.

Conclusion: Cold polypectomy is a safe and effective technique for diminutive/small polyps.

Published: October 2019

Este artigo investiga as experiências de duas professoras mexicanas de inglês que participaram de um programa de mobilidade internacional de desenvolvimento profissional de professores de segunda língua (L2), como monitoras de língua espanhola no Canadá. De uma abordagem narrativa, interpretamos suas experiências nos seguintes aspectos: estrutura curricular do programa de mobilidade; moradia; imersão linguística e aquisição continuada; vivências no Canadá e as experiências com a cultura canadense; aprendizagem pessoal e profissional. Ademais, investigamos como o ensino de primeira língua, no contexto da segunda língua, contribui para o desenvolvimento de professores de segunda língua. Este artigo revê recomendações de um estudo anterior com relação ao reconhecimento profissional, estabelecimento de meta individual - institucional, resultados individuais de aprendizagem linguística - cultural, papel da moradia familiar profissional, à interação com a administração educacional, ao tempo e aos direcionamentos para reflexão. Nossa trama narrativa ecoa o poema “Aninha, a pequena órfã” e o conto “Cachinhos dourados”; e nos leva a reafirmar as recomendações do estudo anterior para um desenvolvimento profissional internacional efetivo de professores de L2 e a sugerir a inclusão de um curso de L2, a nível de graduação, que atenda o foco do programa e crie um espaço relevante de colaboração.
O que os olhos não leem a sociedade sente: a leitura crítica do gênero notícia em sala de aula
Authors: Sampaio Danúbia Aline Silva , De Mello Ana Paula Rezende , Santos Camila de Souza
Published: October 2019

O presente artigo tem como objetivo apresentar uma proposta de trabalho para a leitura de textos (MATTOS, 2011; LDB, 1996; BNCC, 2017) em sala de aula que se paute no conceito de leitura crítica (FREIRE, 1986; CASSANY, 2012; ROVIRA, 2009). As motivações que guiam este estudo partem da recente pesquisa de Cruz e Martiniak (2018) sobre a leitura na Educação Básica brasileira, em que um mapeamento de trabalhos acadêmicos que tratam sobre esse assunto aponta altos índices de deficiência sobre esta habilidade. Como constatação, pode-se perceber que os indicadores negativos se relacionam, sobretudo, aos reflexos gerados por exercícios de compreensão da leitura que se restringem à superfície dos textos trabalhados ao longo das aulas de linguagens. Por isso a necessidade de se propor atividades que vão além da materialidade desses textos. Escolhemos, assim, textos informativos da esfera jornalística, especificamente o gênero notícia, para serem trabalhados com alunos do Ensino Fundamental II, do oitavo e do nono ano. Com aporte teórico da Análise do Discurso (ORLANDI, 1999; CHARAUDEAU, 2013; EMEDIATO, 2013), buscamos trabalhar mecanismos de compreensão textual discutidos nessa teoria que conduzam o professor a explorar a dimensão argumentativa (AMOSSY, 2006, 2011; CHARAUDEAU, 2013) presente no texto do gênero notícia. Dessa maneira, esperamos contribuir com docentes do campo das linguagens para um efetivo trabalho da leitura crítica de notícias em sala de aula, além de refletir sobre a importância de referida abordagem na tentativa de amenizar a deficiência de leitura por ora comprovada.
Desafios contemporâneos na formação de professores de inglês: algumas contribuições dos estudos de Inglês como Língua Franca
Authors: Santos Jacyara Nô dos , Siqueira Sávio
Published: October 2019

O caráter singular da língua inglesa tem contribuído para a produção de uma literatura abundante voltada para o delineamento de uma pedagogia de ensino desse idioma que leve em consideração seu papel de língua franca. Nos últimos anos, a literatura da área de Inglês como Língua Franca (ILF) tem demonstrado grande interesse em apresentar exemplos práticos do que seja ensinar a língua inglesa numa perspectiva de língua franca. De igual modo, muitos trabalhos têm demonstrado a relevância da inserção dos estudos do ILF nos programas de formação de professores de inglês. Neste artigo, partindo de considerações feitas por pesquisadores do campo do ILF (BAYYURT; SIFAKIS, 2017; COGO; SIQUEIRA, 2017; GIMENEZ; EL KADRI; CALVO, 2018; JORDÃO; MARQUES, 2018; SIFAKIS, 2014), discutimos acerca da importância da inserção dos estudos do ILF para a formação docente, levando em consideração o desafio que tal inserção representa, visto que o processo de aprendizagem e  ensino de língua inglesa continua a ser orientado pelo construto do falante nativo.PALAVRAS-CHAVE: Inglês como língua franca; Formação de professores; Ensino de inglês
Ensino de literatura em Língua Inglesa: um diálogo com propostas metodológicas com base na Análise Dialógica da Literatura
Authors: Bandeira de Melo Jr Orison Marden
Published: October 2019

As discussões sobre o ensino de literatura em língua inglesa no Brasil são em número bastante reduzido se comparadas com todas as pesquisas e obras voltadas ao ensino de literatura em língua portuguesa, letramento literário, entre outros. O objetivo deste artigo é discutir o ensino de literatura em língua inglesa a partir da Análise Dialógica da Literatura. Para tal, foram analisadas duas propostas de ensino de literatura em língua portuguesa, a saber, a sequência expandida de Cosson e a proposta dialógica de Cereja, a partir de seis procedimentos analíticos e de três particularidades do texto literário indicados na obra do Círculo (Bakhtin, Volóchinov, Medviédev), a fim de encontrar contribuições e/ou lacunas dessas propostas se transpostas ao ensino de literatura em língua inglesa. Foi possível perceber que, apesar das contribuições que elas trazem para o ensino de literatura, em geral, e de lacunas que se apresentam a partir dos pressupostos da análise dialógica, alguns desafios também surgem, como a questão da heterogeneidade linguística dos(as) discentes e o tempo reduzido que docentes têm para o ensino de literatura em língua inglesa.

Desafíos de la puesta en marcha de la Jurisdicción Especial para la Paz
Authors: Reyes Reyes Magda Stella
Published: October 2019

La aplicación de la Justicia Transicional en Colombia basada en los diálogos y en el acuerdo de paz, desarrolla elementos importantes en relación a la ética del conflicto, la solución negociada y el reconocimiento de las víctimas. Estas herramientas razonables, enmarcadas con sigilo por los distintos protagonistas, como la creación de la Unidad de Búsqueda de Personas Desaparecidas, la Comisión de la Verdad y el Tribunal Especial para la Paz, ha logrado que una iniciativa del Gobierno colombiano y las farc-ep, obtenga el mejor acuerdo posible, con legitimación democrática y un intento de lograr una paz estable y duradera (Reyes Alvarado, 2018). Este año 2017 el desarrollo legal del acuerdo de paz ha esquematizado diversos actos legislativos, múltiples leyes y decretos reglamentarios al interior del sistema judicial colombiano. Existen problemáticas derivadas de las interpretaciones normativas desde el procedimiento y la prueba que se desarrolló de manera transversal en la Jurisdicción Especial para la Paz (jep) con el condicionante del reconocimiento de la verdad y la responsabilidad (artículo transitorio inciso 5 del Acto Legislativo n.° 001 de 2017). Hasta la responsabilidad por la cadena de mando como referente jurídico de impacto en la política criminal y el proceso penal, siendo indispensable realizar una delimitación y análisis de cada caso en concreto, para evitar las persecuciones oportunistas. Este artículo busca desarrollar la conceptualización de estos contenidos y su análisis a la hora de ser puestos de presente en la práctica judicial.

Trabajo ganador del Primer Puesto del Premio “Trabajo de Investigación Clínica - Residentes”,

otorgado por el X Congreso SOLAMI – XXVI Congreso ACMI-ACP, Cartagena 17 – 20 de agosto de 2017.

Introducción: La validez de la relación saturación arterial de oxígeno y fracción inspiratoria de oxígeno (SaO2/FiO2), calculada por oximetría de pulso y por gases arteriales en pacientes con exacerbación de la enfermedad pulmonar obstructiva crónica (E-EPOC) a la altitud de Bogotá no son conocidos, los pacientes con EPOC pueden presentar alteraciones en el intercambio de gases que pueden empeorar con los episodios de broncoespasmo, obtener valores de la SaO2 por oximetría y FiO2 puede brindar información valiosa sobre el curso de la exacerbación.

Objetivo. Determinar la validez de la relación SaO2/FiO2 calculada por oximetría de pulso y por gases arteriales con relación a los desenlaces de ventilación mecánica (VM) y mortalidad a 7 y 30 días.

Métodos. Se realizó un estudio de cohorte prospectivo con análisis de prueba diagnóstica calculando los puntajes DECAF, BAP-65, CURB-65, gases arteriales y oximetría de pulso al ingreso de pacientes con E-EPOC, se evaluó el desenlace de mortalidad a los 7 y 30 días de ingreso y el requerimiento de VM durante su hospitalización, se calculó la relación SaO2/FiO2 utilizando la SaO2 obtenida en los gases arteriales y de manera independiente la relación SaO2/FiO2 con la SaO2 obtenida por oximetría de pulso, con los datos obtenidos se calculó los valores de sensibilidad (S), especificidad (E), valor predictivo positivo (VPP), valor predictivo negativo (VPN), razón de verosimilitud positiva (LR+), razón de verosimilitud negativa (LR-) y área bajo la curva de características operativas del receptor (ACOR).

Resultados. Se analizaron 462 E-EPOC, el requerimiento de VM fue del 14,3% y mortalidad a 30 días del 5,71%, la sensibilidad de la relación SaO2/FiO2 calculada por oximetría de pulso para desenlace de VM fue del 84,6%(IC95%:75-94,2), especificidad 42%(IC95%:37-47), VPP: 19,6%(IC95%:14,8-24,4), VPN: 94,3%(IC95%:90,5-98), LR+: 1,46(IC95%:1,28-1,67), LR: 0,37(IC95%:0,20-1,67), ACOR: 0,779%(IC95%:0,711-0,847) p
FAMÍLIA E DESEMPENHO DE ALUNOS DO ENSINO MÉDIO EM SITUAÇÃO DE VULNERABILIDADE SOCIAL-ESTUDO DE CASO.
Authors: Marucci Fabio , Miranda Antonio Carlos
Published: October 2019

Este artigo apresenta um estudo sobre o desempenho de alunos do Ensino Médio em situação de vulnerabilidade social, tendo como foco uma escola pública estadual da periferia de um município localizado na região Centro-Leste do Estado de São Paulo. O objetivo geral da pesquisa foi evidenciar a relação entre a condição socioeconômica dos alunos e sua proficiência no Saresp. A análise dos resultados permitiu verificar que, de fato, a condição socioeconômica e a situação de vulnerabilidade social que vivenciam têm prejudicado a proficiência desses alunos, pois a escola obteve nota 1,37, numa escala de 0 a 10,0 no IDESP 2014. Os resultados foram verificados, por meio, de uma pesquisa quantitativa com a aplicação de um questionário aos alunos e observações diretas. É importante destacar que as políticas públicas, aplicadas para a educação básica LDB 9.394/96, principalmente em sua etapa final, não estão surtindo o efeito desejado: democratização com qualidade educacional. Com isso, apontamos neste artigo as fragilidades apresentadas pelos vínculos familiares, e sua implicação no sucesso escolar desses jovens.

Authors: DOIMO Diego Augusto , GEBRAN Raimunda Abou
Published: October 2019

The changes resulting from an increasingly diversified education in their social and cultural contexts require the teacher to create new teaching strategies and use different resources, seeking a learning that is conducive to the understanding of the world and critical thinking of students. In this perspective, this study aimed to analyze the Cinema as a teaching resource used to support the philosophy of education in high school, making it possible to think the teaching activities through class itineraries with the use of film. The study methodology included a qualitative approach through literature, document analysis and structuring of class scripts. The results pointed out that in addition to contributing to the philosophical reflection, lecture tours the can raise new looks for a transformative education, promote improvements in teaching practice and prepare citizens aware that they may be authors of their own change.
