Authors: Momma-Bardela Adriana Missae , Guedes-Pinto Ana Lúcia
Published: December 2019

Neste artigo, temos como objetivo focalizar alguns dos sentidos construídos pelas professoras alfabetizadoras sobre a leitura deleite como uma atividade permanente da rotina das práticas pedagógicas desenvolvidas em encontros de formação continuada de professores. A partir de seus dizeres a respeito de como compreenderam esses momentos, procuramos destacar essa abordagem como uma das formas de se trabalhar a dimensão da leitura (dentro de uma proposta alfabetizadora) em que o sujeito é tomado como alguém que se posiciona frente àquilo que lê e vivencia nas práticas formadoras. Para desenvolver nossa reflexão nos baseamos nos resultados da pesquisa intitulada “Formação, Alfabetização e Letramento: a experiência do Pacto Nacional pela Alfabetização na Idade Certa no contexto do estado de São Paulo” (Processo nº408692/2013-8 CNPq). Analisamos alguns fragmentos de entrevistas realizadas com as Professoras Alfabetizadoras (PA) de municípios do estado de São Paulo. A metodologia da pesquisa baseia-se na abordagem qualitativo interpretativa e seguiu os pressupostos da História Oral. Os dizeres das PA apresentam pistas que nos indicam as potências de um trabalho de formação que toma como base a vivência de alguns de seus princípios como forma de que tais vivências possam ser multiplicadas.

Authors: Sheina N. I. , Parshin V. A. , Fedotcheva T. A. , Shimanovsky N. L.
Published: December 2019

A study of the embryo- and fetotoxic effects registered in the antenatal and postnatal periods of development after the intragastric administration of Gestobutanoil in two doses (equitherapeutic and 10 times higher) has been performed. It has been found that the introduction of gestagen Gestobutanoil in both doses did not affect the body weight of pregnant animals, which continued to increase progressively during pregnancy. The embryotropic effect of gestagen was revealed to be dose-dependent. The introduction of gestagen in a dose of 0.25 mg / kg (calculated equitherapeutic dose) had no adverse effect on the development of the embryo and fetus of rats. The gestagen in a dose of 2.5 mg / kg (10 equitherapeutic dose) had a negative effect on the course of pregnancy, which has been manifested by a statistically significant increase in preimplantation death and total fetal mortality, as well as a statistically significant decrease in the number of fetuses. It has been shown that intragastric administration of Gestobutanoil in doses of 0.25 and 2.5 mg / kg to female rats from the 6th to the 19th days of pregnancy did not adversely affect the early development of the first generation offspring (postnatal mortality, body mass dynamics, and development of rats’ sensory-motor reflexes).

Authors: Kulikova O. I. , Fedorova T. N. , Orlova V. S.
Published: December 2019

In recent years, there has been an increase in the prevalence of neurodegenerative diseases including Parkinson’s disease (PD). It is characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to disability of patients and large financial costs of the treatment and rehabilitation. In this regard, the understanding of the environmental factors causing this disease, the development of adequate experimental models for studying its pathogenesis, and the search for strategies to prevent its development, as well as possible neuroprotective drugs, have fundamental scientific value. Although some researchers believe that genetic mutations and aging of the population are the main factors for the development of PD, a lot of studies have shown that PD may be caused by exposure to a number of toxins which enter the body from the environment. This review discusses the main toxic substances that cause the development of PD and, therefore, are used to model this disease in animals and cell cultures, as well as the mechanisms of action of neurotoxins, and the advantages and disadvantages of specific models.

Four polymorphic GABRA2 gene variations: rs105733011, rs8168342, rs198286814, rs198837638 that can influence the formation of different biological effects of the organism when exposed to ethanol have been investigated. For rs105733011 polymorphism the frequency of occurrence of the CT genotype was found to be significantly higher (p < 0,05) among animals with «severe intoxication» – 37,0% than with «mild intoxication» – 14,0%. For rs198286814 polymorphism the tendency to the most frequent occurrence of the AG genotype in the group of animals with «severe intoxication» was established. Significant differences in the distribution of occurrence frequencies of the GG/AG genotypes in the studied groups for polymorphic loci rs8168342 and rs198837638 were not revealed. It was concluded that the rs105733011 polymorphism can be one of the genetic markers allowing to predict the degree of inhibitory action of ethanol in acute alcohol intoxication.

Early Mobilization of Infants Intubated for Acute Respiratory Failure
Authors: Ortmann Laura , Dey Anne
Published: December 2019

Background

Early mobility in the intensive care unit is being promoted as a way to improve outcomes but has not been studied in young infants.

Objective

To determine the safety of a holding intervention for infants intubated for respiratory failure.

Methods

Infants less than 6 months of age intubated for respiratory failure underwent a holding intervention in which a caretaker held the infant at least twice a day once the infant was medically stabilized. Rates of adverse events were compared with historical controls matched by age and Pediatric Index of Mortality 2 score. Vital signs before and during holding were recorded to assess for physiologic tolerance.

Results

Twenty-four infants with a total of 158 holding interventions were studied. Mean holding duration was 99 minutes. Twenty holding interventions were terminated early, most commonly because of agitation. The 24 historical controls had 1 unplanned extubation and 2 arterial catheter removals. The intervention group had no unplanned extubations, inadvertent central catheter removals, or urinary catheter removals and had 1 arterial catheter removal that was not associated with holding. Vital signs before and during holding were similar. There were no differences between the control and intervention groups in duration of intubation (7.3 vs 6.0 days, P = .98), length of intensive care unit stay (9.1 vs 9.0 days, P = .52), or length of hospital stay (11.5 vs 12.5 days, P = .28).

Conclusions

Holding intubated infants in the intensive care unit was well tolerated, without an increase in adverse events.

This study was carried out to identify the relations between macroinvertebrate communities and river basin specific (RBS) pollutants in the Danube River. The investigation was performed at 68 sites along 2,500 km of the Danube. Forward selection (FS), canonical correspondence analyses (CCA), the Spearman correlation coefficient (SC) and BIO-ENV analysis (to detect synergistic effects) were used to identify the relations between the macroinvertebrate dataset and selected biological metrics with RBS pollutants. Of the 20 analysed pollutants (preselected based on NORMAN network methodology), seven (2,4-dinitrophenol, chloroxuron, bromacil, dimefuron, amoxicillin, bentazon and fluoranthene) were found to significantly correlate with macroinvertebrate communities. BIO-ENV analysis revealed 3 subsets of environmental variables that were in high correlation with the biota resemblance matrix, consisting mainly of a combination of the above-mentioned pollutants. Our results indicate that there are significant correlations between chemical determinants and aquatic biota. Moreover, this study contributes to the validation of the methodology used for prioritization of RBS pollutants proposed by the NORMAN network.

Authors: Pelizzo Gloria , Nakib Ghassan , Calcaterra Valeria
Published: December 2019

Minimally invasive surgery (MIS) is widely utilized across multiple surgical disciplines, including gynecology. To date, laparoscopy is considered a common surgical modality in children and adolescents to treat gynecological conditions. Robotic surgical devices were developed to circumvent the limitations of laparoscopy and have expanded the surgical armamentarium with better magnification, dexterity enhanced articulating instruments with 5-7 degrees of freedom, and ability to scale motion thus eliminating physiologic tremor. There are well-documented advantages of MIS over laparotomy, including decreased post-operative pain, shorter recovery times, and better cosmetic results. Indications for MIS in pediatric gynecology are reported in this review and technical considerations are described to highlight new treatment perspectives in children and adolescents, which have already been described in the literature regarding adult patients.
Augustinus: ’n Studie oor die etiek van die kerkvader uit Afrika deur J.H. van Wyk
Authors: Van Wyk Ignatius W.C.
Published: December 2019

In this review article, the book by J.H. (Amie) van Wyk, Augustine: A study on the ethics of the church father from Africa is presented and discussed. Short overviews of the content of the six chapters are given. They are: (1) Introduction – the necessity for a book on Augustine’s ethics in Afrikaans, (2) Orientation – an overview of his life and works, (3) Grounding – the relationship between dogmatics and ethics, (4) Typology – the character of his ethics, (5) Themes – marriage and sexual ethics, political ethics and animal ethics, (6) Findings – evaluation of Augustine’s ethics. Support is given to the argument that Augustine is an important forerunner to the Reformation. Information is provided on Augustine and the early years of the Reformation in Wittenberg. Critical remarks are made about the author’s understanding of the relationship between faith and works, dogmatics and ethics. The Lutheran understanding of this topic is presented as an important alternative to the Reformed version that is defended in this book. Finally, attention is given to Augustine’s ‘theory of the two cities’. Also in this regard advice is given from one of Luther’s publication. His exposition of Mary’s Song (‘Magnificat’) in Luke 1:46–55 is used as an example of how a witness to the government could look like.

Authors: Jacob S. , Karikalan L. , Baskar S. , Gnanavel C.
Published: December 2019

The natural frequencies and damping co-efficient were obtained in a half-cylindrical shell made up of epoxy resin reinforced with glass fibre. The impact load is given by an impact hammer and the effect of impact load is sensed using an accelerometer, which is fixed at the edge of the cylinder. Results are manipulated directly by the system through the accelerometer. The laminated shells were tested with various boundary conditions such as free-free, fixedâ€“fixed and simply supported end. The same tests were conducted on the shells with longitudinal stiffeners. The damping characteristics were compared. From the results it was found that shells without stiffener have a damping co-efficient of 0.177 and the shells with stiffener have a damping co-efficient of 0.311 in free-free end condition. Here it is understood that the shells with stiffener showed 43% improvement in damping co-efficient also. It was also observed that with the addition of rubber particles to the reinforcing polymer, the shells with stiffeners may lead to significant increase in damping co-efficient

Published: December 2019

A nozzle for the aircraft can be designed by considering the exit Mach number. In order to get a premeditated Mach number, we need to convert pressure energy into kinetic energy by using a nozzle. Convergent nozzles are utilized for subsonic flows while Convergent-Divergent (C-D) nozzle is utilized for supersonic flows. Curved nozzle flow is accelerated from low subsonic to sonic velocity at the throat and further expanded to supersonic velocities at the exit, in a C-D nozzle. This paper details the relevancies on designing a curved nozzle to attain super-sonic flow and maximizing the optimal thrust and devoid of flow separation due to shock waves. The navigation of the flow must be parallel to the axis of the nozzle for achieving extreme thrust and proficiency. Based on the fundamental gas dynamic equations, this study aims to develop a theoretical approach for the calculation of the flow properties along the axis of the C-D Nozzle. The flow conditions were selected in consideration of the pressure, temperature and gases accessible at the exit of the combustion chamber.
Advantages of an Innovative Crossed Four Bar Steering Mechanism of a Novel Vehicle
Authors: Pramanik S. , Thipse S.S.
Published: December 2019

A crossed four-bar steering mechanism has been considered for a novel four-wheel vehicle which has different wheel locations compared to a conventional four-wheel vehicle. The present paper discusses the advantages of this newly proposed steering mechanism and the novel vehicle. The steering error curve of this novel vehicle has been compared with that of a conventional four-wheel vehicle having Ackermann steering. When both vehicles move on a curved road, the required angle of rotation of the vehicle wheels due to steering effort will be different and depend on the radius of curvature of the road from place to place. It has been found that the vehicle wheels of novel vehicle need to be rotated by smaller angle for steering. The steering error of the novel vehicle is far less. The swept path width will be reduced if the novel vehicle is used instead of the conventional vehicle.

Published: December 2019

The exploitation of fossil fuels has led to the emerging of gaseous fuel for the automobile engines. The researchers are in the search of producer gas from forest woods. In the process of bio gasification, tar is the major obstacle to produce high efficiency gaseous fuel. In this research work, a catalytic tar mitigation process is framed with nickel (Ni) based catalyst. The Ni based nano Si and Ti catalysts are synthesized using deposition-precipitation method. The synthesized Ni-Si and Ni-Ti catalysts are characterized using scanning electron microscope (SEM) and transmission electron microscope(TEM). The surface area and pore volume are calculated by Brunauer-Emmett-Teller and Barrett-Joyner- Halenda methods to justify the catalytic active surface. A design of experiments (DoE) is framed with L12 design table for the 2 level factors (catalyst, catalyst weight, bed temperature and gas feed rate) for the tar concentration response. The signal to noise (SN) ratio and mean of the factors are analysed to identify the significance. As the outcome of the statistical analysis, it is concluded that the minimum tar concentration of 0.47(mg/Nm3) is attained for the 10% of Ni-Si catalyst with the bed temperature of 800ï‚°C and gas feed rate of 0.01 l/s.

Published: December 2019

Noise test system model of current mechanical and electrical equipment is backward, which is easy to cause low test precision and long time-consuming problems. The afterward noise reduction work cannot be carried out smoothly. For this reason, a new noise test system for airborne electromechanical equipment is designed. The system is based on FPGA and MCU, including the system of power supply, speed sensor, noise sensor and so on. According to the noise measurement algorithm formulated by the International Electrotechnical Commission (IEC), the calculation of frequency and time weights in noise measurement is digitized. The digital processing algorithm of 1/3 octave spectrum analysis is combined to realize the noise test of airborne electromechanical equipment. The experimental results show that the designed system has strong anti-interference, high accuracy of noise testing, fast testing speed and conducive to the implementation of noise reduction work in the later period.
Development and Evaluation of AI System to Specify Favourable Launch Windows of Space Vehicles from the MST Radar Data
Authors: Madhusudan B.P. , Bojja Polaiah
Published: December 2019

Weather being a complex Nondeterministic Polynomial time System, forecasting weather parameters has been a major challenge for so long and continues to be so. To address the pressing challenges, new prediction models are developed that vary in the prediction duration and accuracy. Predicting the wind speed, wind direction and turbulence is of significant interest to rocket industry as that would leverage them to time their launches. Launch vehicle trajectory would use the altitude based on mean wind biasing during atmospheric phase of flight to reduce significantly the effect of atmospheric winds on the structural loads experienced by the vehicle. Biasing the open loop pitch and yaw programs to the mean wind condition of launch month is known as monthly mean wind biasing. Atmospheric phase of flight refers to the wind profile up to 20-25 km altitude, the height resolution and accuracy is important. Diurnal variation on the day of launch is critical. Surface winds are measured at various tower heights up to 150 metres. While upper winds are measured with radiosonde mounted to Rawin balloons or with the expensive and difficult to procure Jimsphere or with MST radars. MST radar is far superior to the traditional radiosonde mounted to Rawin balloons in that the MST radar can be operated on a continuous basis to obtain measurements of the wind. MST Radar data is considered in the present study. Usually, numerical methods involving complex mathematical modelling else statistical estimates are employed for weather forecasting. In this article, an appropriate soft computing technique such as the Feed Forward based Back Propagation Neural Networks is proposed. Neural networks are good at fitting any nonlinear nature of function with several mathematical learning co-efficient variables. Analyses are carried out using MATLAB software for assessing the launch windows of space vehicles and its applications.

Diesel engine combustion simulation requires models of the spray dynamics, chemistry and heat transfer. The interaction between the chemistry and turbulence is one of the major parameters which had been modelled. Combustion simulation has been carried out by using Computational Fluid Dynamics (CFD). CFD model solves three-dimensional Naiver-Stokes equations with k-Îµ turbulence model. Combustion simulation has been carried out for one cycle by considering the two strokes compression and expansion with no load conditions. Fuel injection begins at 725 CA ends at 748 CA. Charge motion within the cylinder, turbulent kinetic energy, peak pressure rise, penetration length, and apparent heat release rate were analysed with respect to crank angle.
Analysis and Improvement on the Structure of Labyrinth Oil Separator
Authors: Xinjie Zhang
Published: December 2019

Based on the CFD analysis on original structure of the labyrinth oil separator, it was discovered that it has low separation efficiency and thus need to be improved. Improvement was made by adding a cyclone oil separator to the original structure which helps to create a second-stage function. The improved structure was verified using CFD analysis. Based on the efficiency of the improved and old oil separator under different working mode, it was discovered that the separator with improved structure has doubled its efficiency.

The construction sector (CS) is an economic barometer that mirrors the state of the economy. Therefore, the construction sector is susceptible to economic impacts. This study investigated the impact of economic shocks (measured with the Gross Domestic Product (GDP)) on construction sector performance. The study used econometric methodology which involves several sequential procedure including unit root test, cointegration test, causality and exogeneity tests. The data used was the Annualized time series data about GDP and construction sector. The data were extracted from the United Nations Statistics Division  database based on the year 2010 US Dollars price over a forty seven (47) year period (1970-2016). The study found that the GDP significantly caused the construction sector output in all tests investigated. The study concluded that the construction sector significantly responded to economic shocks in both the short and long run. The study recommended that government should develop a policy framework that supports a concurrent development of the economy and the construction sector in Nigeria.
Correction to Matsugasaki et al. (2015)

In the article “Two Failed Replications of the Watching Eyes Effect” by K. Matsugasaki, W. Tsukamoto, & Y. Ohtsubo (Letters on Evolutionary Behavioral Science, 2015, Vol. 6, No. 2, pp. 17-20, https://doi.org/10.5178/lebs.2015.36), the results section of Study 2 contained errors. The original version read “the proportion of participants who allocated at least one coin to the next participants was .83 (= 20/24) and .96 (= 23/25) in the eye-image and control conditions, respectively, p = .42 by Fisher’s exact test” (in the left column of p. 19). This should read “the proportion of participants who allocated at least one coin to the next participants was .83 (= 20/24) and .92 (= 23/25) in the control and eye-image conditions, respectively, p = .42 by Fisher’s exact test.”

Abstract. The Sydney Particle Study involved the comprehensive measurement of
meteorology, particles and gases at a location in western Sydney during
February–March 2011 and April–May 2012. The aim of this study was to
increase scientific understanding of particle formation and transformations
in the Sydney airshed. In this paper we describe the methods used to collect
and analyse particle and gaseous samples, as well as the methods employed
for the continuous measurement of particle concentrations, particle
microphysical properties, and gaseous concentrations. This paper also
provides a description of the data collected and is a metadata record for
the data sets published in Keywood et al. (2016a,
https://doi.org/10.4225/08/57903B83D6A5D) and Keywood et al. (2016b,

Environmental controls on marine productivity near Cape St. Francis, South Africa
Authors: Jury Mark R.
Published: December 2019

Abstract. This study considers ocean–atmosphere influences on marine productivity over
the shelf near Cape St. Francis, South Africa. Multiday estimates of
chlorophyll fluorescence in the period 2006–2017 with an area outlined by 34.5–33.75∘ S and
24–26.5∘ E provide the basis for evaluation using data from high-resolution
reanalyses. Correlations with the mean annual cycle of chlorophyll fluorescence were
significant for salinity, linking marine productivity and the coastal
hydrology. A strengthened Agulhas Current induces cyclonic shear that lifts
water at the shelf edge. Composite high-chlorophyll-fluorescence events were
dominated by a large-scale midlatitude atmospheric ridge of high pressure.
The resultant easterly winds caused offshore transport and the upwelling of
cool nutrient-rich water in multiday events at the beginning and end of
austral summer. Environmental controls on interannual fluctuations of the
commercial fishery were also explored. Southwestward currents and diminished
heat fluxes favored the squid catch, while anchovy and sardine catches were linked with
upper northerly wind, consistent with large-scale weather patterns that
underpin coastal upwelling and river discharge. Productivity lags a few days
behind cyclonic wind and current shear and the upstream coastal hydrology,
which shares a common atmospheric driver.

Abstract. The architecture, formation, and modification of oceanic plates are
fundamental to our understanding of key geologic processes of the Earth.
Geophysical surveys were conducted around a site near the Hawaiian Islands
(northeastern Hawaiian North Arch region; Hawaiian North Arch hereafter),
which is one of three potential sites for an International Ocean Discovery
Program mantle drilling proposal for the Pacific plate that was submitted in
2012. The Hawaiian North Arch site is located in 78–81 Ma Cretaceous crust,
which had an estimated full spreading rate of 7–8 cm yr−1. This site fills
a major gap in our understanding of oceanic crust. Previously drilling has
been skewed to young or older crust (<15 or >110 Ma)
and slow-spread crust. P-wave velocity structure in the uppermost mantle of the Hawaiian North Arch shows a strong azimuthal anisotropy, whereas Moho reflections below the basement are variable: strong and continuous, weak, diffuse, or unclear. We assume that the strength of the Moho reflection is related to the aging of the oceanic plate. The Hawaiian volcanic chain (200 km to the southwest of the proposed drill site) and the nearby North Arch
magmatism on the proposed Hawaiian North Arch sites might also have affected
recognition of the Moho via deformation and/or magma intrusion into the
lower crust of the uppermost mantle. This workshop report describes
scientific targets for 2 km deep-ocean drilling in the Hawaiian North Arch
region in order to provide information about the lower crust from unrecovered
age and spreading rate gaps from previous ocean drillings. Other scientific
objectives to be achieved by drilling cores before reaching the target depth
of the project are also described in this report.
Reading the Body in Dickens’s Bleak House and Our Mutual Friend
Authors: Harputlu Shah Zeynep
Published: December 2019

This article examines the ways in which the Victorian body and identity were being transformed in the mid-nineteenth century and identifies three distinctive ways the biological and normative boundaries of the body were violated as represented in Dickens’s fiction: the grotesque body, the vulnerable body and the dead body. In this sense, Dickens’s Bleak House (1851-53) and Our Mutual Friend (1864-65) present creative and challenging literary responses to the Victorian body abjected through deprivation, physical vulnerability and death. In the novels, the grotesque body challenges the abject via a tragicomic and hybrid representation of the body and of character. Regarding the vulnerable body, the study elaborates on a body “out-of-control”, threatening the boundaries between the object and the subject, inside and outside, by holding a liminal state through ill-health, excessive labour, starvation and physical degradation. Finally, it is argued that there was an intimate and abject relationship between the living and the dead bodies in the capital, beside prevalent infant deaths, high mortality rates, diseased bodies and overflowing graveyards in the city.
From Carmageddon and Invizimals to SimCity and Digimon: Blending Patterns in Videogame Titles
Authors: López-Rúa Paula
Published: December 2019

This paper delves into the structure and motivations of blending by reporting on the results of the analysis of a corpus of 80 blends gathered from the field of videogaming. The starting point will be a multidimensional description based on a set of parameters and values drawn on previous works by, among others, Kemmer (2000), Ronneberger-Sibold (2006) and Mattiello (2013). In accordance with the principles of Prototype Theory (Lakoff 1987; Langacker 1987), the combination of values displayed by the items results in an overall degree of typicality and will allow their location in the centre or the periphery of the category. The theoretical framework will be put into practice in the analysis of a corpus of blends naming videogames. Most of them are found to be prototypical items, the most common type being the so-called "overlapping" blend (Splatoon: splat + platoon). Lastly, concerning the motivations for the creation of blends in this particular field, these items succeed in economically capturing key features of the game so as to awaken the interest of potential buyers. Moreover, blends anticipate the humorous, puzzling or creative qualities of the game they name and wink at the players’ inventiveness to work out rules.
The Rhetoric of Persuasion. Talking to Our Emotions
Authors: Fernández-Ulloa Teresa
Published: December 2019

La persuasión se basa en aspectos emocionales. No tiene que ver con argumentos lógicos, sino con recursos que apunten al corazón. El remitente del mensaje intenta cambiar el comportamiento, los sentimientos, las intenciones o el punto de vista de otro por medios comunicativos. Los oradores a los que nos referimos, principalmente políticos, ya que generalmente intentan manipularnos, se dirigen a un grupo con el que tienen algo en común, por ejemplo, raza o religión, y usan miedos y odios, prejuicios e inclinaciones, convicciones e ideales comunes al grupo. Se utilizarán diferentes técnicas para manipular y podemos estudiarlas desde la perspectiva retórica clásica, prestando atención a la elocutio (elementos estilísticos), el ordo (orden) y la dispositio (organización de argumentos), centrándonos en cómo se eligen, repiten o evitan las palabras. El remitente también utilizará discursos anteriores, predicciones sin ninguna base y otras estrategias para infundir miedo en los destinatarios (el Otro es una amenaza). Además, debemos considerar los diferentes canales que existen actualmente para difundir ideas, como lo harán los autores de los diferentes artículos de este número especial.
Incumbent versus Non-Incumbent Persuasive Speech: 2017 New York Mayoral Elections
Authors: López Cirugeda Isabel
Published: December 2019

En noviembre de 2017, el candidato demócrata Bill de Blasio revalidó su reelección como alcalde de Nueva York frente a la republicana Nicole Malliotakis y el independiente Bo Dietl. Aunque sin duda muchas circunstancias influyeron en el resultado final, tales como sus diferentes niveles de popularidad o el contenido de sus programas, el discurso político juega un papel siempre decisivo. Por esta razón, se propone un análisis de las funciones persuasivas de los candidatos. En concreto, este artículo analiza el lenguaje retórico y figurativo de los candidatos en el momento clave de la campaña: el debate final, celebrado el 1 de noviembre, a la luz de las teorías del Análisis del Discurso Político (van Dijk, 1997, 2011, Fairclough & Fairclough, 2013), que hunde sus raíces en la Retórica de Aristóteles, a través de su revisión por parte de Charteris- Black (2011), la Teoría de Cortesía (Brown & Levinson, 1987) y la noción de imagen (Goffman, 1956, 1967), polarización (van Dijk, 1993, Chilton, 2004), y eufemismo y disfemismo (Allan & Burridge, 1991) para detectar y comparar las estrategias entre los candidatos según su condición de alcalde en funciones o de aspirante desde el punto de vista del discurso político.
