Vehicle Drive Control Using Fuzzy Based PI Speed Controller
Authors: Shakya Dr. Subarna
Published: May 2020

This paper proposes a fuzzy PI speed controller which is used in electric vehicle’s drive control system insensitive to parameter change and disturbance, using fuzzy control theory. A permanent magnet synchronous motor (PMSM) is modelled mathematically in d-q reference frame. In this paper, a sliding model and fuzzy control theory are used to simulate the PMSM models using fuzzy control theory. Simulink software is used to analyze and simulate the simulation models which show that the proposed PI control based on fuzzy logic will have better anti-interference, better dynamic performance, and faster dynamic response speed when compared with the sliding motor control. Hence the proposed methodology is considered to be the ideal control method with a predefined vector control reference value for the electric vehicle’s motor.

Published: May 2020

The adhoc networks are the platforms formed for specific reason to attain a specific purpose. It is a communication strategy followed by the wireless devices when or while the actual communication setup is not possible. Any portable device communicating in the wireless medium in a decentralized manner is termed to be a wireless adhoc network. One such device is the wireless-sensors that imitate the aforementioned procedures to send the information from the source to the target falls under the category of the wireless adhoc network, as it communicates through the air in a wireless medium. The rapid proliferation of sensors and growing demand for applications and services from the network formed using such wireless-sensors generate unrivaled appeals for routing data packets on infrastructure of the network formed using the wireless-sensors. Such sensors lays as the fundamental devices in a wide range application and are even more predominant in the internet of things paradigm. Numerous of such devices are used in the internet of things to gather enormous amount of data from a broad range of applications. The sensors used in the internet of thing usually performs the sensed data transmission to the gateway-nodes through the public channel that are insecure for conversing the confidential data. So the routing with authentication becomes essential, to make the routing robust and long lasting it is necessary to develop a light weight authentication scheme that does not consume too much of the energy of the network of the wireless-sensors. To handle this problem the paper concatenates the unique key generation technique the mid-square (Mid-S) with the Beziers curve based authentication (UKHA) to secure and authenticate the routing between the wireless-sensor networks framed in adhoc manner and the gate way nodes of the internet of things platform. The proposed protocol for routing is develop in the MATLAB and simulated in it to manifest the proficiency of the developed protocol on the terms of the energy consumption, packet deliver rate, percentage of losses incurred and running time.

Published: May 2020

The swift progress in the computing set up by providing services has caused the sudden increase in the amount of the services that are operationally similar. The dissimilarity in such services are observed based on the characteristics standards of their service quality. Consequently a thought-provoking issue in the perspective of the service-configuration is based on the choosing the accurate client services according to the user demands for which the acquired compound services guarantees the non-computational demands on the ground of comprehensive service quality constraints. The procedure carried out in the paper presents the novel algorithm for the service composition/configuration for enhancing the quality of service of the compound /composite computing services. The algorithm focusses in improve the service configuration feasibility and optimality and minimize the configuration time. The algorithm is totally based on the limits in the configuration strategies that relies on the Pareto-Dominance and the quality of service decomposition (PD-QOSD). The quantity of the service arrangements is expected to increase according to the service count and quality of service characteristics in case of PD and whereas the QOSD takes care of the feasibility of the arrangements during the high restrictions imposed by users on the constraints of the comprehensive quality of service. The validation outcomes prove that the novel algorithm developed function efficiently on the basis of the time required for composition, the optimality, as well as the search space.

The decentralized network formed without any assistance of the fixed infrastructure and just by the employing the volunteering mobile or the portable devices that work in a cooperative manner along with the other devices that are clubbed in the network are inbuilt with the capacity of providing a best data conveyance facility utilizing the unicast, multicast and the broadcast methods of the routing strategies. Despite the capabilities of these type of networks, it faces difficulties in devising a strategy of routing according to the dynamic nature of the distributed network. The reactive type or the on demand routing are highly used over the proactive way of routing in the decentralized network as the performance of the former is better compared to the latter. As the mobile device employed are capable are moving from its position irrespective of time, and they behave as the route and as well as the end node or the initiating node. The important factors to be considered while forming the route is the power required for transmission and the current position of the nodes, this is quiet tedious. The study in the paper provides the importance of the on demand routing distance vector routing for the distributed network that are linked in a adhoc manner and analysis all the existing on demand distance vector routing strategies and form a new manifold route discovery scheme to improve the conventional_AODV. The method devised to improve the conventional_AODV proves to be efficient when simulated using the NS-3 on the basis of the packet delivery rate, load balancing and the energy usage.

Authors: Hwang Byung-Hak , Kim Jang Soo , Oh Jaeseong , Yu Sang-Hoon
Published: May 2020

The linearization coefficient $\mathcal{L}(L_{n_1}(x)\dots L_{n_k}(x))$ of classical Laguerre polynomials $L_n(x)$ is known to be equal to the number of $(n_1,\dots,n_k)$-derangements, which are permutations with a certain condition. Kasraoui, Stanton and Zeng found a $q$-analog of this result using $q$-Laguerre polynomials with two parameters $q$ and $y$. Their formula expresses the linearization coefficient of $q$-Laguerre polynomials as the generating function for $(n_1,\dots,n_k)$-derangements with two statistics counting weak excedances and crossings. In this paper their result is proved by constructing a sign-reversing involution on marked perfect matchings.

Published: May 2020

Hops flowers are used to impart highly desirable hoppy aromas in beer. The emergence of craft brewing caused an increase in the popularity of intense hoppy beer determining a breeding trend for new hop flavour varieties that differ in terms of oil contents and compounds. The aim of this work is to examine the relationship between volatile organic compounds (VOCs) and sensory properties in an Italian craft beer brewed with 2 selected Italian wild hop varieties and a commercial one (Cascade) grown in 2 sites with different environmental condition. Since the beer aroma is represented by hop flowers and so they increase incise in the finished product. In this study, 6 beer samples produced by an Italian microbrewery using hop plants were collected and analysed for Volatile Organic Compounds (VOCs) profiles  using a PTR-TOF-MS and a sensory evaluation (panel and consumer tests). Multivariate statistical analyses (PCA and CANOCO) showed as “Cascade commercial” sample marks with the highest intensity of taste  in comparison to other samples. Results showed low interest for the aromas the hops imparted to the beers produced in relationships to the commercial variety grown and bought. In addition, the grown commercial cascade resulted to be interesting, producing a modified aroma profile when compared to its commercial counterpart. Finally, this study showed an initial contribution  to screen other wild genotypes to identify new hops for direct use or breeding with new characteristics that can be used for the production of beer with a modified aroma.

Authors: Bambang Kuswandi  , Mahawan A. G. Nuriman
Published: May 2020

A color indicator for tape ketan (TK) (Indonesian fermented steamed glutinous rice product) packaging was developed to monitor the fermentation stage of TK during storage and distribution. Tape ketan was packed in a tray of polypropylene (PP) with a lid of nylon/cast polypropylene (Ny/CPP). A color indicator film consisting of Nafion® and crystal violet (CV) was attached to the lid as an on-package indicator and change its color as water vapor or relative humidity changes. During fermentation at ambient temperature (28±1°C), the TK quality was assessed for pH, titratable acidity (TA), ethanol content and sensory evaluation (aroma, taste, and color), in correlation with the color change of the indicator. In conclusion, the color values of the indicator correlated well with sensory values as a degree for fermentation stage of TK along with other parameters, such as pH, TA, and ethanol, and could be detected clearly with yellow for unripe, blue for ripe, and finally pale blue for overripe.

A method for detection and quantitative determination of aflatoxins (AFs) produced by Aspergillus flavus in Pistachia vera seeds (pistachio) using Fourier transform infrared spectroscopy, coupled with Diffuse Reflectance Infrared Fourier Transform Spectroscopy (FTIR-DRIFT) is examined in this study. Greek medicinal and aromatic plant extracts with established bioactivity against A. flavus AFs production were used as treatments on pistachio seeds. Classes were analyzed using discriminate analysis algorithm, and distance values were calculated in Mahalanobis distance units. Strong absorptions were detected in the spectral ranges between 1750 and 1500 cm-1, which were different in contaminated and not contaminated samples. The spectra regions that gave matching values less than 50.00 in absolute difference for AFs in pistachio paste samples were 1705 – 1575 cm-1 and 1350 - 900 cm-1. Also, the high performance of FTIR as analytical tool for quantitative estimation of AFs was emerged by the Partial Least Square (PLS) regression model that found to fit perfectly the actual concentration values (R2=99.99%) in combination with low levels of errors of calibration, validation and prediction along with a minimum and low-cost sample preparation. The developed methodology presents a great potential of a valuable and reliable technique for composition determination, differentiation and evaluation of AFs in food products. We also aimed to reduce sample preparation in the methodology described and to include pistachio and plant extract matrix in classification demonstrating the suitability of FTIR DRIFT spectroscopic methods for direct AFs detection and quantification in biorefineries and industry.

Authors: Habibian Mahmood , Sadeghi Ghorbanali , Karimi Ahmad
Published: May 2020

A systematic study was conducted about the solvent effect on the purslane total phenolic, flavonoid, alkaloid, carotenoid, saponin, vitamin E, and vitamin C contents as well as to evaluate their contribution to overall antioxidant activity. Among three solvents investigated, water could extract the highest levels of solid and saponin contents, whereas methanol was more effective for obtaining phenolic, flavonoid, and alkaloid compounds than other solvents. Meanwhile, ethanol was the best choice for extracting carotenoids and vitamin E. In various experimental models including DPPH radical scavenging activity, ABTS+ radical scavenging activity, and ferric reducing antioxidant power, methanol extract consistently showed significantly greater antioxidant activity than other extracts, while ethanol extract provided the most efficient inhibiting activity against ferrous chloride-induced oxidation of linoleic acid. In addition, the scavenging efficiency of ethanol extract toward DPPH and ABTS+ radicals was significantly higher than the water extract, and vice versa was the case for ferric reducing antioxidant power. Overall, methanol was found to be the most favorable solvent for the extraction of phenolic, flavonoid, and alkaloid compounds that are promising as natural antioxidants. However, different solvents may be used to extract specific antioxidant compounds with distinctive antioxidant activity.
Changes Required to Sustain a Best Value Environment

Published: May 2020

The BV environment was introduced into the Netherlands in 2004. By 2008 testing was being done by a partnership between Arizona State University and Scenter (private entity led by Sicco Santema). In 2010, the $1B fast track projects were procured by the Rijkswaterstaat, using the Best Value Procurement. By 2015, instead of the BV approach being treated as just another option, NEVI, the Dutch professional procurement group (third largest procurement group in the world) designated the Best Value Procurement as one of the main stream procurement approaches, and hired a full time Director to guide their Best Value Procurement training programs. However, in three major areas: IT delivery, professional services and the medical arena, buyers and larger-traditional vendors were having difficulty adapting to the approach. The BV approach utilizes the expertise of experts to replace the need for owner management, direction and control (MDC). However, a stumbling block occurred, when a “Best Value” vendor was selected, but did not have their detailed plan as a baseline from which they could identify risk that was outside of their control, their risk mitigation plan, and a simple way to create transparency to help the client/user. This is a case study that shows how the Best Value Approach was requiring a paradigm shift with both the user and the vendor, which neither party was well-prepared for.

Design choices: Empirical recommendations for designing two-dimensional finger-tracking experiments
Authors: Wirth Robert , Foerster Anna , Kunde Wilfried , Pfister Roland
Published: May 2020

The continuous tracking of mouse or finger movements has become an increasingly popular research method for investigating cognitive and motivational processes such as decision-making, action-planning, and executive functions. In the present paper, we evaluate and discuss how apparently trivial design choices of researchers may impact participants’ behavior and, consequently, a study’s results. We first provide a thorough comparison of mouse- and finger-tracking setups on the basis of a Simon task. We then vary a comprehensive set of design factors, including spatial layout, movement extent, time of stimulus onset, size of the target areas, and hit detection in a finger-tracking variant of this task. We explore the impact of these variations on a broad spectrum of movement parameters that are typically used to describe movement trajectories. Based on our findings, we suggest several recommendations for best practice that avoid some of the pitfalls of the methodology. Keeping these recommendations in mind will allow for informed decisions when planning and conducting future tracking experiments.

Published: May 2020

Single-layer vanadium nitride (VN) and bilayer Pd0.96Fe0.04/VN and VN/Pd0.92Fe0.08 thin-film heterostructures for possible spintronics applications were synthesized on (001)-oriented single-crystalline magnesium oxide (MgO) substrates utilizing a four-chamber ultrahigh vacuum deposition and analysis system. The VN layers were reactively magnetron sputtered from a metallic vanadium target in Ar/N2 plasma, while the Pd1−xFex layers were deposited by co-evaporation of metallic Pd and Fe pellets from calibrated effusion cells in a molecular beam epitaxy chamber. The VN stoichiometry and Pd1−xFex composition were controlled by X-ray photoelectron spectroscopy. In situ low-energy electron diffraction and ex situ X-ray diffraction show that the 30 nm thick single-layer VN as well as the double-layer VN(30 nm)/Pd0.92Fe0.08(12 nm) and Pd0.96Fe0.04(20 nm)/VN(30 nm) structures have grown cube-on-cube epitaxially. Electric resistance measurements demonstrate a metallic-type temperature dependence for the VN film with a small residual resistivity of 9 μΩ·cm at 10 K, indicating high purity and structural quality of the film. The transition to the superconducting state was observed at 7.7 K for the VN film, at 7.2 K for the Pd0.96Fe0.04/VN structure and at 6.1 K for the VN/Pd0.92Fe0.08 structure with the critical temperature decreasing due to the proximity effect. Contrary to expectations, all transitions were very sharp with the width ranging from 25 mK for the VN film to 50 mK for the VN/Pd0.92Fe0.08 structure. We propose epitaxial single-crystalline thin films of VN and heteroepitaxial Pd1−xFex/VN and VN/Pd1−xFex (x ≤ 0.08) structures grown on MgO(001) as the materials of a choice for the improvement of superconducting magnetic random access memory characteristics.

Published: May 2020

Recent advances in the chemistry of peptides containing fluorinated phenylalanines (Phe) represents a hot topic in drug research over the last few decades. ᴅ- or ʟ-fluorinated phenylalanines have had considerable industrial and pharmaceutical applications and they have been expanded also to play an important role as potential enzyme inhibitors as well as therapeutic agents and topography imaging of tumor ecosystems using PET. Incorporation of fluorinated aromatic amino acids into proteins increases their catabolic stability especially in therapeutic proteins and peptide-based vaccines. This review seeks to summarize the different synthetic approaches in the literature to prepare ᴅ- or ʟ-fluorinated phenylalanines and their pharmaceutical applications with a focus on published synthetic methods that introduce fluorine into the phenyl, the β-carbon or the α-carbon of ᴅ-or ʟ-phenylalanines.

Published: May 2020

Summary. Objective: to determine the prognostic value of the factors influencing the outcome of treatment of plantar fasciitis, to develop a system for predicting the results of treatment of plantar fasciitis.

Materials and Methods. Analysis of long-term results of conservative treatment of 145 patients with plantar fasciitis. Clinical, instrumental and statistical (correlation-regression analysis) research methods were used. The factors that influenced the end result of treatment were identified.

Results. The statistically significant influence of age, gender, disease duration up to 6 months, BMI up to 25, the presence of “functional” equinus, pronated foot and history of treatment on the prevalence of positive treatment results were determined. The estimation of the informative nature of the presented factors for the probability of achieving positive results of treatment, the calculation of the prognostic coefficients and their sum were determined. A high prognostic evaluation of a successful treatment outcome should be expected with a total prognosis of +5 to +25; a total estimate of prognostic coefficients from -15 to +5 determines the average probability of positive treatment results; the sum of the prognostic coefficients from -34 to -15 determines the low probability of achieving positive treatment results.

Conclusions. The result of treatment of plantar fasciitis depends on age, sex, duration of the disease up to 6 months, BMI, "functional" equinus, pronated foot, and medical history. The system for predicting treatment outcomes involves the possibility of obtaining high, medium and low probability of a positive result when applying conservative treatment.
Determination of Sensitivity of Сlinical Strains of S. aureus Isolated from Patients with Orthopedic and Traumatological Pathology to the Antibacterial Agent “Piophagus”
Authors: Liutko O.B. , Vytrak K.V. , Mytiakyna Y.Iu.
Published: May 2020

Summary. The resistance of clinical microorganism strains isolated in modern hospitals to the corresponding antimicrobial agents, namely antibiotics, is increasing from year to year. Knowledge of the existence of a natural antimicrobial agent that can penetrate the necessary parts of the body and selectively fight pathogens is very desirable in modern medicine. Bacteriophages are one of the most promising alternatives to antibiotics for practical use. In the past, testing of phage therapy has already taken place with the implementation of numerous experimental and practical studies. However, the lack of standardized standards and their planned implementation can explain the infrequent use in practice of this method in the treatment of infectious diseases or postoperative infectious complications at present. A limitation is also the fact that the therapeutic effect after treatment with bacteriophages varies widely and has certain features. This, in general, is associated with the features of different loci when using such drugs and various sensitivity of microorganism strains to a single phage or their combination. Today, there is a better understanding of the pharmacology, immunology, safety and potential of bacterial resistance of phages. There is a growing number of well-performed clinical trials describing the effectiveness of phage therapy. New technologies provide tools to optimize the treatment strategies. The work analyzes the sensitivity of clinical strains of S. aureus isolated from patients with orthopedic and traumatological pathology, and preliminary generalizations are made. The revealed patterns can be used as the results of standardized monitoring of clinical strains of S. aureus in the case of a decrease in the effectiveness of antibiotic therapy in accordance with modern requirements and the transition to phage therapy in practice.

Summary. A retrospective analysis of case histories and radiographs of 138 patients with hip-lumbar syndrome who underwent hip joint replacement in the clinic of orthopedics and adult traumatology at the ITO NAMS of Ukraine was carried out. It has been determined that the variant of vertical posture, acting on the morphogenesis of coxarthrosis, determines the rate of its progression. It was determined that in the presence of hip-lumbar syndrome, a moderate form of CA progression most often occurs, regardless of the type of lordosis. The slow rate of progression of coxarthrosis is characteristic of hyper- and normolordosis. Hypolordosis is statistically significant (p < 0,05) characterized by a faster course of the pathological process in the hip joint than other types of lordosis. The studies will contribute to the further development of the clinical diagnostic and therapeutic algorithm for patients with hip-lumbar syndrome.

Reconstructive surgery was performed on patients from 6 months to 2 years after the injury. Among the methods of rehabilitation treatment, chronic epidural electrical stimulation of the spinal cord (as the first stage of rehabilitation treatment) was used in all patients, neurotization of the anterior interosseous nerve (anterior interosseous nerve AIN) by the branch of the muscular cutaneous nerve – in 38 patients, transposition of the tendon of the deltoid muscle to the tendon of the triceps of the shoulder – in 8 patients.

Results. The ASIA impairment scale, SCIM (Spinal cord independence measure scale) and MRC (Medical Research Council scale) were used to evaluate treatment outcomes. The results were evaluated 18 months after reconstructive surgery. In the ASIA A group, the quality of life improved in 74.4% of patients, due to an improvement of the upper extremity function. In the ASIA B group, an improvement in the quality of life was noted in 83.7% of patients, both due to improved self-care and mobility, and due to improved control of the function of the pelvic organs. In the ASIA C group, improved quality of life was mainly due to improved mobility.

Conclusions. Complex restorative treatment of patients with incomplete cervical spinal cord injury allowed to improve the quality of life due to correction of segmentary and conductive violations of the spinal cord. In patients with complete spinal cord injury, only segmentary violations are suitable for correction.
Bone Densitometry Indices of Humerus Bone in Patients with Partial Rupture of the Supraspinatus Tendon
Authors: Strafun S.S. , Bohdan S.V. , Abbasov S.M.
Published: May 2020

Summary. Bone density is an important factor that affects the strength of the suture of the tendons of the rotator cuff. The higher the bone density is, the greater is the strength of fixation of the supraspinatus tendon to the bone, since the anchor is more securely fixed in the bone.

Objective: to determine the bone mineral density of the proximal humeral epiphysis in patients with partial tear of the supraspinatus tendon.

Materials and Methods. An X-ray examination of 48 shoulder joints (24 with partial tear of the supraspinatus tendon and 24 intact contralateral) was performed in 24 patients with partial tear of the supraspinatus tendon. On the electronic photographic prints of X-rays with the help of the specified software, 2 standard for all patients zones of determination of mineral density of bone tissue, both on the extremity with partial rupture of the supraspinatus tendon and on similar parts of the contralateral limb, were found. The bone mineral density (BMD) measurement zones were placed as follows: 1st zone - the greater tubercle of the humerus; 2nd zone - the middle of the humeral head. Each zone had a square shape and corresponded to 0.9±0.15 cm² of the area of the standard radiograph. Also, all patients underwent standard radiographic examination of the hip joints and lumbar spine.

Conclusions: In zone 1 (the greater tubercle of the humerus), the bone mineral density of the limb with partial tear of the supraspinatus tendon reached 0.167±0.155 g/cm² and was slightly lower than that on the healthy limb 0.238±0.115 g/cm² (p<0.05). This indicates the effect of partial rupture of the supraspinatus tendon on the development of osteoporotic processes in the area of the greater tubercle of the humerus. In the 2nd zone (the middle of the humeral head), the average bone mineral density of the limb with partial rupture of the supraspinatus tendon reached 0.193±0.109 g/cm² and was also less than 0.245±0.159 g/cm² on the contralateral limb. In the 1st zone (the greater tubercle of the humerus), the dependence of changes in bone mineral density on the total changes in bone mineral density (r=0.62; p<0.01) was revealed. In zone 2 (r=0.14; p<0.01), bone mineral density was independent of overall changes in bone mineral density.
Options for compensation of bone defects in revision knee replacement (Literature Review)
Authors: Sulyma O.M.
Published: May 2020

Summary. Modern domestic and foreign literature was analyzed to determine the tactics of surgical treatment of patients during the revision knee replacement. It was found that the use in clinical practice of a larger number of methods for compensating bone defects in revision knee replacement convincingly indicates the unresolved nature of this problem and the need for further scientific development, clinical research and observation. Using this or that method, it is necessary to take into account its advantages and disadvantages, as well as the specific clinical and physical characteristics of each patient.
Modern Bécquer?
Authors: Mandrell James
Published: May 2020

Though the question of Gustavo Adolfo Bécquer’s modernity has been a touchstone of critical discussion since the Rimas were first published posthumously in 1871, a definitive answer has proven elusive. A reading of rima VIII in the context of Giacomo Leopardi’s “L’Infinito” reopens the question in unexpected ways. This comparison, with recourse to the sublime and Kant, suggests that it’s possible to read Bécquer as Romantic or modern according to the reader and what is read.
Retratos y Apuntes Literarios (1908), de Emilia Pardo Bazán
Authors: Sánchez-Llama Iñigo
Published: May 2020

Emilia Pardo Bazán evalúa en Retratos y apuntes literarios (1908) las principales corrientes literarias españolas desarrolladas durante el siglo XIX. La autora efectúa un balance sobre la literatura española decimonónica desde una perspectiva moderna que enfatiza la dimensión estética de las obras analizadas. Pardo Bazán propone integrar la tradición cultural autóctona—interpretada en clave moderna—con las tendencias foráneas adscritas a la modernidad. otra contribución importante en su articulación de la modernidad al hispánico modo radica en su revisión de los categorías estéticas patriarcales consolidadas en las letras españolas de la Restauración (1874-1931).
El clasicismo extemporáneo de Jesús Urueta (1890-1900)
Authors: Pascual Gay Juan
Published: May 2020

Jesús Urueta (1867-1920) participó tempranamente del grupo modernista encabezado por José Juan Tablada que en 1894 accede a la Revista Azul dirigida por Manuel Gutiérrez Nájera. Después de una década profesando la fe modernista, se marcha a Italia a cursar estudios de derecho. Allí conoce a Ferrari y forma en las doctrinas de Lombroso. Tutelado por Justo Sierra, a su regreso a México en 1901, asume ya el compromiso cívico del intelectual moderno surgido del caso Dreyfus. Estas líneas dan cuenta de los primeros años de actividad literaria y de su cambio de postura al regreso.
Las contradicciones del “idealismo hispánico”
Authors: Arbaiza Diana
Published: May 2020

Hacia finales del XIX, escritores y empresarios españoles coincidían en describir la emigración a América Latina como instrumento que regeneraría a España moralmente, un retrato que eludía el aporte fundamental que la emigración suponía para las finanzas españolas. Estos ambages respecto al aspecto económico de la migración respondían en gran parte a la construcción discursiva del “idealismo hispánico” como rasgo identitario de españoles y latinoamericanos frente a un materialismo anglosajón. Este concepto surgió a finales del XIX para combatir el imaginario que representaba a los países hispánicos como un Otro del capitalismo occidental, pero también dificultó el apoyo expreso a proyectos comerciales, que frecuentemente se articulaban con una retórica de regeneración social. Este trabajo analiza las ambigüedades y contradicciones en las que incurren los textos a favor de la emigración económica, explorando las tensiones de presentar al emigrante transcendiendo de figura económica a agente de transformación social.
EL PROYECTO PEDAGÓGICO EN LA PRODUCCIÓN LITERARIA DE EMILIA PARDO BAZÁN
Authors: Sánchez-Llama Iñigo
Published: May 2020

El interés de Emilia Pardo Bazán por la pedagogía es una constante en su trayectoria intelectual. La autora propone durante la década de 1890 la necesaria incorporación de la mujer española a las tendencias modernas mediante la pedagogía. Artículos en revistas especializadas y ponencias leídas en Congresos Pedagógicos confirman este interés de Pardo Bazán. La novela Memorias de un solterón (1896) es quizá la ficción en la que la escritora textualiza sus inquietudes pedagógicas de una manera más precisa. La singular contribución de Pardo Bazán radica en construir un complejo discurso feminista en el que se entrecruzan la representación del género, las tendencias de la moderna pedagogía y un ideario regenerador asociado con la modernidad instaurada desde la Ilustración.
