Comparing abnormalities in onshore and offshore vertical wind profiles
Authors: Møller Mathias , Domagalski Piotr , Sætran Lars Roar
Published: March 2020

Abstract. Understanding the vertical wind profile is paramount for design and operation of wind turbines. It is needed not only for extrapolation of the wind velocity to hub height but also for structural load calculations, to name the most obvious issues. As wind turbines grow in size and development transitions offshore, issues such as shallow surface layers, low-level jets (LLJs) and internal boundary layers (IBLs) are raising questions concerning the applicability of the commonly used Monin–Obukhov similarity theory to accurately describe the vertical wind development at modern wind turbine hub heights. In this study the 10 min averaged vertical wind profile up to a minimum elevation of 100 m is analyzed through measurements collected from seven sites which represent a span of conditions. Three sites are located offshore in the North Sea and Baltic Sea (FINO1, FINO2 and FINO3) with varying fetch, two onshore by the Norwegian coast (Frøya and Valsneset), one further onshore by the Danish coast (Høvsøre), and one inland at a forested site in Sweden (Ryningsnäs). Through analysis of data series ranging from 8 months to several years depending on the site, the wind profile has been quantitatively categorized according to the number of exhibited local maxima which is not possible within the Monin–Obukhov similarity theory. The results reveal that the occurrence of local maxima is higher at sites of low surface roughness and a high prevalence of unstable atmospheric conditions, causing up to 17 % severely inflected abnormal profiles at the most exposed offshore site, which decreases as the location transitions from offshore to coastal to further inland and is lowest at the forested site. The results indicate that issues in predicting the vertical wind profile are most prevalent offshore, where very stable inflections cause severe deviations which may be related to an offshore internal boundary layer. These findings suggest that there is evident need of an improved vertical wind profile description in order to improve the accuracy of power predictions and load calculations, especially at offshore and coastal sites.
Wake steering optimization under uncertainty
Authors: Quick Julian , King Jennifer , King Ryan N. , Hamlington Peter E. , Dykes Katherine
Published: March 2020

Abstract. Turbines in wind power plants experience significant power losses when wakes from upstream turbines affect the energy production of downstream turbines. A promising plant-level control strategy to reduce these losses is wake steering, where upstream turbines are yawed to direct wakes away from downstream turbines. However, there are significant uncertainties in many aspects of the wake steering problem. For example, infield sensors do not give perfect information, and inflow to the plant is complex and difficult to forecast with available information, even over short time periods. Here, we formulate and solve an optimization under uncertainty (OUU) problem for determining optimal plant-level wake steering strategies in the presence of independent uncertainties in the direction, speed, turbulence intensity, and shear of the incoming wind, as well as in turbine yaw positions. The OUU wake steering strategy is first examined for a two-turbine test case to explore the impacts of different types of inflow uncertainties, and it is then demonstrated for a more realistic 11-turbine wind power plant. Of the sources of uncertainty considered, we find that wake steering strategies are most sensitive to uncertainties in the wind speed and direction. When maximizing expected power production, the OUU strategy also tends to favor smaller yaw angles, which have been shown in previous work to reduce turbine loading. Ultimately, the plant-level wake steering strategy formulated using an OUU approach yields 0.48 % more expected annual energy production for the 11-turbine wind plant than a strategy that neglects uncertainty when considering stochastic inputs. Thus, not only does the present OUU strategy produce more power in realistic conditions, but it also reduces risk by prescribing strategies that call for less extreme yaw angles.

Purpose: To investigate the effect of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, on inflammatory cytokines of urogenital tissue in a rat model of type 2 diabetes (T2DM) to infer pharmaceutical influence of dapagliflozin on genitourinary infection or inflammation.Methods: Study animals were divided into the following 4 groups of 10 animals each: (1) the Otsuka Long-Evans Tokushima Fatty (OLETF)-DA group treated with dapagliflozin at 1.0 mg/kg/day, (2) the OLETF-VO group treated with voglibose at 0.6 mg/kg/day, (3) the control group (OLETF-CO) given water, and (4) the Long-Evans Tokushima Otsuka (LETO) rats were included as nondiabetic control group. Changes in blood glucose, 24-hour urine volume, and urine glucose were measured. The interleukin-1β (IL-1β) and interleukin-18 (IL-18) levels in the bladder and the urethra were quantified, respectively.Results: The urine glucose level and the 24-hour urine volume at 12 weeks of treatment were significantly higher in the OLETF-DA group than that in any other group (P<0.05). The cytokine analysis of the bladder and urethra showed higher IL18 and IL-1β in the OLETF-DA and the OLETF-CO groups than that in the OLETF-VO and LETO groups (P<0.05). The cytokine levels did not differ between the OLETF-DA and the OLETF-CO groups, and the level of IL-18 in the OLETF-DA group was higher in the urethra than in the bladder.Conclusions: This study revealed that dapagliflozin increased the urine glucose concentration, resulting in an inflammatory response remain in the urogenital tract as the untreated diabetic rats. Therefore, when treating patients with T2DM with dapagliflozin, careful attention should be paid to genitourinary infection or inflammation.
Robotic Simple Prostatectomy: Why and How?
Authors: Cho Jeong Man , Moon Kyong Tae , Yoo Tag Keun
Published: March 2020

Increasingly many studies have presented robotic simple prostatectomy (RSP) as a surgical treatment option for large benign prostatic hyperplasia (BPH) weighing 80–100 g or more. In this review, some frequently used RSP techniques are described, along with an analysis of the literature on the efficacy and complications of RSP and differences in treatment results compared with other surgical methods. RSP has the advantage of a short learning curve for surgeons with experience in robotic surgery. Severe complications are rare in patients who undergo RSP, and RSP facilitates the simultaneous treatment of important comorbid diseases such as bladder stones and bladder diverticula. In conclusion, RSP can be recommended as a safe and effective minimally invasive treatment for large BPH.

Published: March 2020

Objective: To evaluate the effect of a stoma nursing care program on the personal adjustment to an ostomy. Materials and methods: A quasi-experimental study with a control group. The sample of 105 patients with stoma was divided into two groups (intervention group and control group), with assessments in the first and sixth month after hospital discharge. Information was collected using the Elimination Ostomy Adjustment Scale. Student’s t-tests analysis were performed. Results: One month after hospital discharge, the adjustment to the stoma was satisfactory and similar (p > 0.05) in both groups, and in the sixth month, statistically more favorable in the intervention group (p < 0.001); a statistically significant difference between the two assessments (p < 0.001) is found in the intervention group only. Conclusions: The intervention program has a positive influence on the adjustment to the stoma, and its contribution is significant six months after hospital discharge. Systematic interventions of an ostomy care specialized nurse have shown positive effects on ostomy adjustment, which is recommended since the preoperative period.
Using Arabic in Teaching English to Arabic-Speaking Learners (From Teachers’ and Students’ Point of View)
Authors: Ahmed Elawad Yagoub
Published: March 2020

The aim of this study was to investigate and analyse teachers’ and students’ views towards using Arabic in teaching English in secondary schools in Oneizah Province, Saudi Arabia. The data were collected by means of two questionnaires: one for teachers and the other for students. The subjects were 43 teachers of English, 12 were female. 120 male students from four different secondary schools in Oneizah. The results of the study showed that Arabic language (The students’ mother tongue) could be used during English language lessons although teachers’ responses gave less support for using Arabic. Also, the results revealed that Arabic has positive roles to play in teaching English besides facilitating learning process. The recommendations emphasize and encourage teachers and supervisors to pay attention to their learners need in using their mother tongue. Moreover, Arabic language can be a means of facilitation not a hindrance so it can be used in many activities inside the classroom without affecting students’ exposure to English language. Also, there should be a place for learners’ mother tongue in the syllabus, e.g. in translation exercises and bilingual dictionaries.
A Review on the Book of A Study of Metonymy Through the Lens of Rhetorical Criticism
Authors: Tian Yuhan
Published: March 2020

This paper reviews the book of A Study of Metonymy through the Lens of Rhetorical Criticism. In this book, the author, Li Ke, tries to analyze and evaluate metonymy through the lens of rhetorical criticism, and proposes a new research paradigm called critical metonymy analysis based on which metonymic competence is well constructed that can be applied to teaching practice. He finds that the research horizon of metonymy has been mainly confined to traditional linguistics in the past, hardly involving interdisciplinary research. Besides, domestic studies are inclined to merely introduce western research achievement, lacking original theories and research methods. Therefore, this book is of great value in both theoretical and practical aspects. Besides the advantages, this book can be refined by adding objects of critical metonymy analysis to extend its linguistic data. In addition, it can also be improved by classifying and analyzing these data systematically.
The Impacts of Soy-Based Biodiesel on the Main Soy Producers in the International Market
Authors: Alvim Augusto Mussi , Fochezatto Adelar
Published: March 2020

This study analyzes the impacts of soy-based biodiesel consumption on the main soybean-producing countries. To achieve this goal, a partial equilibrium model formulated as a Mixed Complementarity Problem (PCM) is used, which allows the inclusion of trade barriers and the construction of alternative scenarios. Four scenarios are analyzed. The first simulates a demand shock for soybean meal and soybean oil, considering the observed growth in demand over the last ten years. The second evaluates the effects of an increase in the demand for meal, oil and biodiesel. The third considers the elimination of the demand for soy-based biodiesel. The last scenario assesses the effects of the elimination of tariffs and subsidies on the grain and food markets. In general terms, the results show that: in the second scenario, Brazil is the only exporting country that shows a greater increase in consumption than in production, reflecting the country’s smaller share in the world soybean trade; in the fourth scenario the gains are relatively smaller than the potential gains in the first scenario; in the third scenario, soybean prices are about 8% higher because of the use of soybeans for biodiesel production, demonstrating the relevance of mandatory policies in this market.

Published: March 2020

This paper aims at discovering a suitable theory for understanding the adoption of renewable energy (RE) among investors and decision-makers in the Egyptian market as well as disclosing the research gaps related to examining the drivers that affect spreading RE sources in the various societies. Finally, it will explore the factors that influence the adoption of RE in different organizations to increase the diffusion of RE inside the Egyptian society. Therefore, it is important to understand how business customers select the type of energy whether conventional energy or RE or mixed. Hence, this study examines the drivers that influence business customers’ choices of RE versus conventional energy for pushing toward adopting the RE investment inside the firms. Exploratory research is used in this investigation; therefore, data for this study is collected using literature reviews, international and local reports, in addition to unstructured interviews with potential and actual customers as well as practitioners and academics in the RE sector. This study will benefit Egyptian policymakers and RE companies in the marketing of RE sources through understanding the drivers of adopting RE within businesses.
Sounding the Feminine in Sor Juana’s Villancicos to St. Catherine of Alexandria (1691)
Authors: Finley Sarah
Published: March 2020

This article attends to intersections of auditory and feminine tropes in Sor Juana’s villancicos for St. Catherine. The purpose is to draw out resonances among sonorities related to the Alexandrine saint and representations of learned women elsewhere in the poet’s writing. My central argument is that aurality in the St. Catherine cycle deepens the defense of women’s learning and also relates to female exemplarity and agency. Broadly, the study engages the auditory turn in literary and cultural studies and lends a sonorous perspective to discussions of knowledge and gender in Sor Juana’s oeuvre.
The Beauty of Holiness: Architectural Representations of the Temple of Jerusalem in Spanish Golden Age Poetry
Authors: Kaplis-Hohwald Laurie
Published: March 2020

This essay is a comparative analysis of three texts of major poets of Spain’s Golden Age: Luis de Góngora, Lope de Vega, and Juan de Jáuregui. The poets worked with a common trope, sharing a worldview that blended themes of Hebrew kingship with the Spanish Habsburg dynasty. The poems are based on the concept of Spanish Solomonism, and are related by inventive, and very different, evocations of the Temple of Jerusalem as the seat of Christian monarchy, holiness, and visual beauty.
Factores que inciden en la deserción estudiantil de la Carrera Ingeniería en Sistemas de Información en la FAREM-Estelí, UNAN-Managua. Nicaragua
Authors: Rizo Rodríguez Marlene
Published: March 2020

Este estudio estuvo dirigido a valorar los factores que incidieron en la deserción de la carrera de Ingeniería en Sistemas de Información en la Facultad Regional Multidisciplinaria Estelí (FAREM Estelí), durante el período 2010-2013. Surge a partir de que representantes estudiantiles de la carrera exponen en Asamblea General a las autoridades de la Facultad la preocupación porque cada día son menos los estudiantes en los diferentes grupos; así como al verificar que las cifras de deserción proporcionada por la oficina de Registro Académico de la FAREM y concluir que efectivamente son considerablemente altas. Se sitúa dentro del paradigma cualitativo, con algunos elementos cuantitativos. Dentro del campo educativo se ubica como investigación aplicada porque se presenta un plan de retención para la carrera, producto de las ideas aportadas por los informantes y de la documentación revisada. El estudio indica que los principales factores que inciden en la deserción son : a) socioeconómico, la mayoría cuenta únicamente con el respaldo de las madres; b) laboral, dado que los estudiantes que trabajaban no contaban con apoyo de las empresas, c) personal, porque presentan bajo rendimiento académico, los hábitos de estudio no son suficientes y sostienen que la carrera es compleja y d) institucional, por la falta de cobertura con becas, el 63% de los estudiantes desertores no fueron beneficiados con ningún tipo de beca. Basado en los factores que más incidieron en la deserción se proponen acciones estratégicas contempladas en un plan de retención como alternativas de mejora para disminuir la misma en la carrera.
Risk Factors for Re-Revision Surgery in Shoulder Arthroplasty
Authors: Dillon Mark T. , Prentice Heather A. , Burfeind William E. , Singh Anshuman
Published: March 2020

Introduction:

Revision shoulder arthroplasty is an expensive undertaking with notable morbidity to the patient and less predictable outcomes. Therefore, it is important to avoid even further surgery in these patients. We sought to report the annual revision burden from a large integrated healthcare system and identify patient and operative factors that may predispose patients to revision failure, necessitating further surgery.

Methods:

Annual revision burden as a proportion of the overall shoulder arthroplasties performed from 2005 to 2017 was obtained. Patients who underwent aseptic revision between 2005 and 2017 comprised the study sample. Patient characteristics evaluated for re-revision risk included age, sex, body mass index (BMI), race, and diabetes status, whereas surgical characteristics included surgeon cumulative revision volume, revision procedure type, and top reason for revision by primary procedure type. Multivariable Cox proportional hazards regression was used to evaluate the association between the specified factors and re-revision risk.

Results:

From 2005 to 2017, revisions represented 5.3% to 7.8% of all shoulder arthroplasty procedures performed. Factors associated with re-revision surgery risk by procedure type included increasing BMI and hemiarthroplasty revision procedure compared with reverse total shoulder arthroplasty (RTSA) revision procedure for hemiarthroplasty primaries; diabetes, revision because of instability, and lower cumulative surgeon revision procedure volume for RTSA primaries; and TSA revision procedure compared with RTSA revision procedure for TSA primaries.

Conclusion:

The annual revision shoulder arthroplasty volume increased over the study period. Patient factors, including BMI and diabetes were associated with higher re-revision risks for hemiarthroplasty and RTSA primaries, respectively. RTSA revised for instability had a higher risk of re-revision compared with other indications. TSA and hemiarthroplasty requiring aseptic revision may be best treated with RTSA as opposed to another TSA or hemiarthroplasty. Further studies are needed to verify these findings and identify how the mechanism of failure may affect the procedure selection in the revision setting.

Study on the Labor Population Structure and Human Capital Accumulation Characteristics of Different Industries in China
Authors: Hua Wen
Published: March 2020

Based on the data of China Labor Statistical Yearbook, this paper analyzes the characteristics of the labor population structure and human capital accumulation by industry, and finds that the labor population structure presents the following characteristics: (1) the Labour force is concentrated in service industry; (2) the proportion of labor force in emerging and high skilled industries is small; (3) there is age structure differentiation among industries. The accumulation of human capital is characterized by: (1) a shortage of human capital accumulation in productive industries; (2) a large gap in human capital accumulation in different industries. Therefore, no matter from the perspective of labor population structure or human capital accumulation, there are some structural differentiation problems among different industries, which is directly related to the enjoyment of second demographic dividend. Therefore, we must pay attention to the structural differentiation of labor population distribution and human capital accumulation among industries, and improve the education and training system, employment security system, labor mobility system as well as social security system, so as to eliminate the second demographic dividend barrier caused by structural differentiation.

The Hyper-Kloosterman code was first defined over finite fields by Chinen-Hiramatsu, see (Chinen, & Hiramatsu, 2001). In the present paper we define the Hyper-Kloosterman codes over Galois rings R(pe;m). We show that this code is the trace of linear code over R(pe;m). By the Hyper-Kloostermann sums over Galois rings, we determine the Hamming weight of any codeword of this code over Galois rings.

Moving Beyond Sustainability: A Regenerative Community Development Framework for Co-creating Thriving Living Systems and Its Application
Authors: Gibbons Leah V.
Published: March 2020

Sustainable development and design have the potential to shift their aim from improving human well-being within environmental limits to catalyzing thriving social-ecological communities (i.e., living systems) across scales. Regenerative development (RD), a methodology that harnesses the potential of living systems, offers a way forward. RD integrates science and practice with essential but often neglected components of sustainability—ecological, social, cultural, spiritual, and geophysical—as well as their temporal and spatial dynamics. It also addresses the root causes of (un)sustainability—thinking and worldviews. This research creates and pilots the first community-scale RD framework (RCD Framework) in a developing intentional community. Findings indicate that the RCD Framework achieves its intended aim of facilitating shifts in thinking and development and design concepts toward holistic and regenerative. Factors that are conducive to or impede RCD are identified, and suggestions are made for advancing RCD science and practice. Implications for larger communities, cities, regions, and sustainable development and design are discussed.
Pine Wood Particles Pyrolysis and Radiographic Analysis
Authors: Kazimierski Paweł , Vieira Sara , Kardaś Dariusz
Published: March 2020

The goal of this experiment is to assess the mass and volume loss of medium size pine wood particles undergoing pyrolysis. Wood samples of different sizes and shapes were pyrolysed at 500 ºC with different residence times. A thermogravimetric analysis was carried out for comparison purposes. Finally, the pyrolysed samples were analysed using radiographic methods. A connection between the different analyses was found. For larger particles, the heating rate is lower, and a time gap between hemicellulose and cellulose thermal decomposition was noticed. Research shows that an important part of the analysis of the process is the rate of biomass heating and sample size. As the sample size increases, the pyrolysis time increases; however, the increase is not linear. The publication also shows the great possibilities of radiographic methods in analysing the pyrolysis process.
Effect of Water Repellents on Hygroscopicity and Dimensional Stability of Densified Fir and Aspen Woods
Authors: Pelit Huseyin , Emiroglu Fatih
Published: March 2020

This study investigated the effect of pre-impregnation with water-repellent agents on the hygroscopicity and dimensional stability of fir (Abies bornmulleriana Mattf.) and aspen (Populus tremula L.) woods. After pre-vacuum treatment, the samples were impregnated at atmospheric pressure with paraffin, linseed oil and styrene, and then densified at compression rates of 20 % and 40 % at 120, 150 and 180 °C. The results showed that water repellents significantly affected the hygroscopicity and dimensional stability of the densified wood samples. Compression recovery rate (CRR), thickness swelling (TS), equilibrium moisture content (EMC), and water absorption (WA) values of the densified samples decreased with impregnation pretreatments. The linseed oil treatment gave more positive CRR and TS results than paraffin. Lower EMC and WA values were found in the paraffin-treated samples. However, the most successful results for all tested properties were determined in the styrene pretreated samples in which hygroscopicity decreased and dimensional stability increased (especially for aspen) due to increases in the compression rate and temperature related to densification conditions. In the styrene pretreated samples, the high temperature (180 °C) and compression rate (40 %) significantly reduced CRR, TS, EMC and WA, total dimensional stability was nearly achieved and the water repellent effectiveness was close to 100 %.
Properties of Plywood Produced with Urea-Formaldehyde Adhesive Modified with Nanocellulose and Microcellulose
Authors: Kawalerczyk Jakub , Dziurka Dorota , Mirski Radosław , Szentner Kinga
Published: March 2020

Urea-formaldehyde adhesives are widely used in the wood-based materials industry. The study investigates the possibility of using cellulosic particles as a filler that modifies the properties of the resin and consequently improves the properties of plywood. Moreover, the study also examines the differences between microcellulose and nanocellulose used as a filler for UF adhesive. Based on the investigations, it was found that the addition of MFC and NCC significantly affected the curing process and rheological behaviour of adhesive mixtures. Modification led to increase of viscosity and extension of a gel time caused by lowering solid content of the resin. The experimental and reference plywood were tested in terms of bonding quality and mechanical properties such as modulus of elasticity and modulus of rigidity in accordance with applicable standards. The results of the tests confirmed that both the amount and the type of modifier added to the resin had a significant effect on the properties of plywood. The bonding quality and the above mentioned mechanical properties improved in all variants of modification; however the most effective was the addition of NCC in the amount of 10 %/100 g of solid resin. The slight decrease of formaldehyde emission was only observed for 5 % cellulosic particles added to 100 g of solid UF.

Published: March 2020

In this study, we developed a robust automatic computer vision system for marbling meat segmentation. Our approach can segment muscle fat in various marbled meat samples using images acquired with different quality devices in an uncontrolled environment, where there was external ambient light and artificial light; thus, professionals can apply this method without specialized knowledge in terms of sample treatments or equipment, as well as without disruption to normal procedures, thereby obtaining a robust solution. The proposed approach for marbling segmentation is based on data clustering and dynamic thresholding. Experiments were performed using two datasets that comprised 82 images of 41 longissimus dorsi muscles acquired by different sampling devices. The experimental results showed that the computer vision system performed well with over 98% accuracy and a low number of false positives, regardless of the acquisition device employed.

Published: March 2020

OBJECTIVE: The quality of paediatric clinical practice guidelines (CPGs) for the management of Mycobacterium tuberculosis infection is unclear. We aimed to comprehensively assess the quality of these CPGs and identify areas requiring improvement.DESIGN: CPGs
were systematically searched and identified before being appraised by independent reviewers using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) and Reporting Items for Practice Guidelines in HealThcare (RIGHT) tools. Inter-rater reliability was assessed using intra-class
correlation coefficient (ICC).RESULTS: Twenty-five CPGs were evaluated. All CPG agreements among four reviewers were good (ICC 0.753–0.939). The mean CPG score was 50.5% (23.5–78.4%), and seven CPGs were recommended for use. The mean scores of three domains were low:
38% for stakeholder involvement (5.6–93.1%), 38.4% for rigour of development (1–97.4%) and 36.3% for applicability (12.5–64.6%). The mean reporting rate of Reporting Items for Practice Guidelines in HealThcare fields was 41.8%, and the evidence field had the highest reporting
rate (63.1%), while the review and quality assurance field had the lowest rate (15.4%) for CPGs that include methods.CONCLUSION: The methodological and reporting quality of the CPGs was variable and poor, respectively. More effort is needed in stakeholder involvement, rigour of
development, applicability domains and reporting to produce higher-quality CPGs.

Published: March 2020

The article is devoted to the actual problem of developing the cognitive and reading activity of junior pupils. The author’s technique of formation the research skills of junior pupils at literary reading lessons is highlighted.
The leading conditions for the implementation of the technique are the use of such modes as “immersion” of children into the world of landscape lyrics by means of various kinds of art (literature, painting, photography, music); stimulation of creative self expression and children’s reading activity in their study of poetry (group research on creation of a score of expressive reading, linguistic experiment, comparative analysis of one or different authors’ works as well as works belonging to different kinds of art); introduction of research training methods : the search for a problem that is going to be investigated on the material of a literary work; formulation of problem solving questions by pupils that will form the basis of the training task (on ascertainment of cause-and-effect relationships; on formation of ability to think critically, defend their personal position; on comparison and confrontation); joint working out an action plan to answer a problematic question; individual search activity; meaningful answer to the problem question).
We have come to the conclusion that the proposed method of work on familiarization of junior schoolchildren with literary works on the principles of research approach will help to form students’ continuous interest in reading, to activate readership, to prepare for independent, creative acquaintance with new works at literary reading lessons on the basis of formed research skills.

New characterizations of spacelike hyperplanes in the steady state space
Authors: Aquino Cícero P. , Baltazar Halyson I. , De Lima Henrique F.
Published: March 2020

In this article, we deal with complete spacelike hypersurfaces immersed in an open region of the de Sitter space $\mathbb {S}^{n+1}_{1}$ which is known as the steady state space $\mathcal {H}^{n+1}$. Under suitable constraints on the behavior of the higher order mean curvatures of these hypersurfaces, we are able to prove that they must be spacelike hyperplanes of $\mathcal {H}^{n+1}$. Furthermore, through the analysis of the hyperbolic cylinders of $\mathcal {H}^{n+1}$, we discuss the importance of the main hypothesis in our results. Our approach is based on a generalized maximum principle at infinity for complete Riemannian manifolds.

Une lettre de Jean Dorat sur l’oeuvre de Nonnos
Authors: McShane Myron
Published: March 2020

Dans une lettre à un correspondant anonyme, le poète humaniste français Jean Dorat exprime son point de vue sur l’oeuvre de Nonnos, poète grec de l’Antiquité tardive, juste avant d’entreprendre la conception du programme littéraire fondé sur lesDionysiaques, le plus long poème de l’Antiquité, pour l’entrée royale de 1571 à Paris. Voilà près de 70 ans que la lettre a été imprimée, pourtant l’identification de ce correspondant anonyme reste toujours problématique. Certains commentateurs ont proposé le nom de Gérard Falkenburg, philologue renommé et premier éditeur desDionysiaques. Dans cet article, nous présenterons la première traduction de la lettre néolatine de Dorat et nous identifierons son destinataire au poète et patricien gantois Charles Utenhove. Cette nouvelle identification du correspondant de Dorat nous permettra de réévaluer la réception de l’oeuvre de Nonnos et, plus généralement, la réception de la poésie épique grecque et de la paraphrase biblique auxvie siècle. L’oeuvre poétique et épistolaire d’Utenhove, écrite en néo-latin, en français et en grec, s’étale sur plus de quarante ans. Tout au long de son oeuvre, Utenhove a chanté les louanges et a contribué à la diffusion de deux ouvrages nonniens : lesDionysiaqueset laParaphraseen vers de l’Évangile selon saint Jean. Bien que les spécialistes mentionnent parfois Utenhove comme traducteur desDionysiaqueset de laParaphrase, les textes les plus pertinents sont rassemblés ici afin de permettre d’évaluer la contribution réelle, longtemps ignorée, de l’humaniste flamand à la diffusion de ces deux oeuvres de Nonnos à la Renaissance.
Ce que la lettre familière fait au discours médical. Une lecture de la lettre XIX, 16 des Lettres de Pasquier (1619)
Authors: Autiquet Benoît
Published: March 2020

L’article porte sur la lettre XIX, 16 du second tome desLettresde Pasquier, publié en 1619. Cette lettre, qui traite de la science médicale de l’époque de l’auteur, est généralement lue comme un lieu où Pasquier, refusant les dogmes médicaux au nom du scepticisme, fait valoir la vérité de l’expérience personnelle en matière médicale. Nous essayons de montrer au contraire que, loin de valoriser uniquement le savoir individuel, cette lettre, très critique envers les dogmes médicaux, propose néanmoins des formes institutionnelles du savoir médical. Mais celles-ci, contrairement aux « écoles » antiques, ne sont pas construites autour d’un centre dogmatique. Deux modèles institutionnels, concurrents et parfois contradictoires, sont proposés par l’auteur : un modèle divin, qui fait des médecins des agents de Dieu ; un modèle humain, où les médecins ont le rôle de « compilateurs » des remèdes locaux qui, conformément à la théorie médicale des climats, sont les seuls à pouvoir soigner les habitants d’un lieu. On propose, en fin de parcours, une tentative pour articuler ces deux modèles.
Comunicação pública na prevenção da evasão: a experiência de um aplicativo sobre Ensino Médio Integrado
Authors: Almeida Elisa Carmo Franco , Miranda Paula Reis de
Published: March 2020

A principal causa de evasão escolar no Ensino Médio Integrado (EMI) do IF Sudeste MG — Campus Rio Pomba é a falta de conhecimento sobre a identidade dos cursos integrados, que sujeita os estudantes a surpresas pós-ingresso. Considerando-se tal distanciamento entre a instituição e o público-alvo da Educação Profissional e Tecnológica, o presente estudo buscou validar a hipótese de que um aplicativo para dispositivos móveis, voltado a aproximar estudantes adolescentes, constituiria um potencial aliado do Campus Rio Pomba na prevenção da evasão escolar. Tal hipótese relaciona-se ao comprometimento com a trajetória acadêmica, a instituição e a carreira, compreendido como um fator de permanência. Assim, realizou-se um estudo de caso voltado ao curso integrado com maior índice de evasão do Campus Rio Pomba: o de Agropecuária. Revisão bibliográfica, estudo de experiências educacionais recentes, com tecnologia e análise de resultados de entrevistas com estudantes externos ao IF Sudeste MG compuseram o estudo e embasaram a criação de um protótipo de aplicativo em formato interativo, contendo informações curriculares, imagens, vídeos e outros recursos voltados ao curso em questão. O protótipo foi testado pelos mesmos sujeitos adolescentes entrevistados, e seus relatos em questionários apontam que a tecnologia foi capaz de ampliar o conhecimento sobre o IF Sudeste MG e o curso de Agropecuária na modalidade integrada, além de modificar perspectivas de futuro. Validou-se, portanto, a hipótese inicial: o aplicativo proposto apresenta potencial de prevenção da evasão, ao combater a principal origem do problema  — o desconhecimento.
Lecionar e pesquisar na educação básica: a atividade investigativa como caminho formativo para professores de português
Authors: Falcão Gabriela Lins , Suassuna Livia
Published: March 2020

Com o presente artigo, objetivamos contribuir para a discussão acerca do desenvolvimento de pesquisa pelo professor de português no âmbito da educação básica brasileira.  A partir da noção de professor pesquisador e da análise dos dispositivos legais que normatizam a profissão docente no Brasil, o tema é tratado com base na articulação de estudos desenvolvidos nas áreas da formação de professores (ANDRÉ, 2001; CONTRERAS, 2002; DINIZ-PEREIRA e ZEICHNER, 2011; IMBERNON, 2016; GATTI, 2017 LÜDKE, 2000 e 2001 PIMENTA, 2012; TARDIF e MOSCOSO, 2018) e do ensino de língua (ANTUNES, 2003 e 2007; DORNELLA, 2007; GERALDI, 1996, 1997 e 2018; ILARI, 1997; PIETRI, 2003; SOARES, 2001). Os achados desta investigação indicam avanços no tocante à abordagem do tema nos diferentes campos de estudo e nas normativas oficiais, mas ressaltam os entraves existentes para a efetivação de propostas dessa natureza, tendo em vista a necessária efetivação das melhorias previstas nas condições de trabalho do professor pesquisador em atividade nesse nível da educação. Por outro lado, reafirmam a prática da pesquisa como caminho possível para a reconfiguração do trabalho docente, no tocante a questões relativas à autonomia desse profissional e a seu reconhecimento como produtor de conhecimento, bem como seu potencial para contribuir com a construção de práticas de ensino inovadoras, em consonância com os estudos linguísticos mais atuais.
Aprendizagem por meio do ensino híbrido na educação superior: narrando o engajamento dos estudantes
Authors: Rodrigues do Nascimento Ernandes , Padilha Maria Auxiliadora
Published: March 2020

Este artigo apresenta resultados de uma pesquisa realizada de fevereiro a junho de 2019 que buscou conhecer como 50 estudantes do ensino superior dos cursos de tecnologia se envolvem em sua formação por meio do ensino híbrido. Objetivou-se identificar o engajamento estudantil e entender os desafios que os estudantes enfrentam ao estudar a partir de um modelo pedagógico inovador. Os dados foram construídos através de um grupo focal, dos diários de aprendizagem dos estudantes e da aplicação de uma escala de envolvimento. Para analisar os dados, utilizou-se a análise teórica para descobrir as conexões entre os resultados e descrevendo os achados. Os resultados apontaram que uma pequena parcela dos estudantes prefere o ensino tradicional, cerca de 14%. Porém, a maioria admitiu ter se engajado mais estudando por meio desse modelo pedagógico, mesmo tendo que superar desafios diários. Eles afirmaram que não desejariam voltar ao modelo tradicional, pois sentiram que suas aprendizagens foram mais profundas e significativas.
Educação popular e trabalhos autogestionários: iniciativas operando (re)arranjos em territórios vulneráveis
Authors: Belli Maria José Menezes Lourega , Boneti Lindomar Wessler
Published: March 2020

O presente artigo tem como objetivo analisar a educação popular como prática geradora de laços de convivência que potencializem ações comunitárias, transformando condições de vulnerabilidade em espaços ambientalmente sustentáveis. Metodologicamente, esse movimento de aprendizagem compartilhada, geradora de realizações, será analisado por meio da reconstituição do itinerário da Irmã Tereza Araújo e do CEFURIA. A abordagem se propõe desvelar e analisar os reposicionamentos desses atores em ambientes de aprendizagem geradores de problematizações sobre suas condições sociais em meio a mercados modelados por trocas emocionais, simbólicas, produtivas e financeiras. Compreender as posições e posicionamentos desses grupos com seus interlocutores possibilitou identificar suas parcerias junto a esferas institucionais, bem como analisar os (re)arranjos solidários como práticas pedagógicas, onde esquemas mentais foram formados através de repertórios provenientes de vivências, capazes de agregar transformações em microterritórios urbanos. Desses encontros surgiram comunidades de aprendizagem, visões diferentes chegaram a consensos, dos esforços individuais ocorreram convergências pela cooperação. Quando se instalou essa rede de interdependência, as contradições emergiram, eram proferidas em rodas de conversa, assim o senso crítico ganhava terreno ampliando as margens de luta por uma cidade mais inclusiva e democrática. No que se refere aos caminhos teóricos, adotaram-se no estudo Freire e Freire (2014), Polanyi (2000), Porto‑Gonçalves (2006), Sen (2010) e Gadoti (1991). Assim, a Associação de Moradores Santo Inácio de Loyola e o CEFURIA possibilitaram examinar um conjunto de situações e sistemas de pensamento que substituíram resignação pela opção de reorganizar suas vidas.
Autoavaliação institucional da Universidade Federal da Paraíba: diagnóstico a partir da Comissão Própria de Avaliação
Authors: Souza Saulo Rodrigo Alves de , Guerra Maria das Graças Gonçalves Vieira
Published: March 2020

Este artigo teve como objetivo analisar os cinco últimos Relatórios de Autoavaliação Institucional da Universidade Federal da Paraíba (UFPB), elaborados pela Comissão Própria de Avaliação (CPA) da instituição, tendo por referencial o Instrumento de Avaliação Institucional (IAIE) de 2017. Esta investigação tem abordagem qualitativa, com estratégia bibliográfico-documental. Utilizou-se a análise SWOT como ferramenta administrativa para identificação das forças, fraquezas, oportunidades e ameaças que impactaram — positiva ou negativamente — na qualidade da educação ofertada pela UFPB. Esta pesquisa constatou que, de um total de cinquenta indicadores do IAIE de 2017, do SINAES, os processos de autoavaliação institucional analisados contemplaram apenas três, em conformidade com os RAAIs disponibilizados, concluindo-se que os processos analisados não atenderam às dez dimensões previstas no SINAES, o que inviabiliza uma visão global da IFES.

Published: March 2020

Entende-se que o professor, ao conhecer seu estilo de ensino, pode alinhar de maneira mais adequada as estratégias de ensino, para contribuir com a aprendizagem significativa do aluno, segundo o seu estilo de aprendizagem. Nesse sentido, o objetivo principal deste artigo foi evidenciar como os estilos de aprendizagem contribuem com processo de ensino na educação básica e no ensino superior. Visando alcançar o objetivo proposto, realizou-se uma pesquisa exploratória, a partir de um levantamento sistemático da literatura, com o intuito de se buscar produções nas bases de dados do Portal de Periódicos da CAPES, ProQuest e SCOPUS, que focam os estilos de aprendizagem segundo a teoria de Alonso, Gallego e Honey (1994). Os critérios de inclusão adotados foram: teoria de Alonso, Gallego e Honey; sem parâmetro quanto ao período de publicação; artigos e/ou anais de eventos; independentemente do qualis do periódico e/ou evento. Portanto, a identificação dos estilos de aprendizagem pode ser um ponto de partida para a sistematização do complexo processo de ensino e de aprendizagem. Entende-se que o reconhecimento desses estilos pode contribuir com a minimização das lacunas existentes no processo de ensino e aprendizagem, uma vez que podem ser utilizados no contexto escolar para se abordar o currículo, nos diferentes níveis de ensino, de forma mais efetiva e significativa
