Authors: Shende Mulchand A. , Chavan Kajal D
Published: November 2019

SeDeM design expert technique used to evaluate the risks of poor flow of pharmaceutical powders under preformulation studies which reveals direct compression suitability and prepare robust composition of active pharmaceutical ingredient (API) and excipient in tablets formulation. The purpose of this study was to develop oral disintegrating tablets of Furosemide using different concentration of natural and synthetic superdisintegrants by means of SeDeM design technique. Oral disintegrating tablets (ODT) of Furosemide were prepared by direct compression technique using isolated banana powder and croscarmellose sodium (Ac-di-sol) together with microcrystalline cellulose as superdisintegrants. SeDeM design was performed to check suitability and deficient of excipients and drug for optimized composition derived based on IPP value. These tablets were evaluated for hardness, friability, drug content, weight variation, wetting time and in-vitro dissolution. All the formulations showed low weight variation with dispersion time less than 173.5±0.70 seconds and rapid in-vitro dissolution. The drug content of all the formulations was within the acceptable limits. Lubricated blend composition of F4 found average radius value 5.24, 0.66 and 5.509 for IGC, IP and IPP respectively, compressed tablet shown good physical properties. The optimized formulation F4 showed good release profile with 99.25 percentage drug release compared to other trial batches. It was concluded that natural superdisintegrant (banana powder) showed better disintegrating property than synthetic super disintegrant (Ac-di-sol) in the formulations of ODTs.

Published: November 2019

Modern drug discovery has led to the development of drug molecules that exhibit high lipophilicity and poor water solubility, which leads to problematic bioavailability. Approaches have thus been made to enhance dissolution of poorly water soluble drugs through modifications and creation of specific formulations. Metaclopramide is an antiemetic and gastroprokinetic agent, commonly used to treat nausea and vomiting. It is absorbed well after oral administration but a significant first pass effect in some human patients may reduce systemic bioavailability to 30%.The Metaclopramide base is thus modified from Metaclopramide hydrochloride to enhance solubility .This has been achieved by the formulating in solid dispersion since Metaclopramide is poorly water soluble. Though it is absorbed well after oral administration, a significant first pass effect in some patients reduces systemic bioavailability, which can cause adverse side effects. This solid dispersion has then been used through transdermal drug delivery. Enhancement of solubility of poorly water soluble drug by solid dispersion may be attributed to particles modified characters such as particle size reduction, improved wettability, higher porosity, decreased lattice energy, amorphous state. The main objective thus includes modification of drug Metaclopramide  hydrochloride to Metaclopramide base, preparation of solid dispersion of modified Metaclopramide  base drug which has poor water solubility, experimental analysis of Metaclopramide base drug and solid dispersion products with carriers.

Compliance management in family firms: A systematic literature analysis
Authors: Stefan Behringer , Patrick Ulrich , Anjuli Unruh
Published: November 2019

Family firms play an important economic role in Europe and in the world. The discussion of compliance-relevant issues has long been attributed to capital market-oriented large companies. So far, there have been few findings on the perception, dissemination and implementation of this concept in family businesses. The purpose of this paper is to provide a systematic and iterative literature review of available research on compliance management and corruption in family firms. Thereby a total of 47 articles on the topic were identified. The review acknowledged that Compliance/Corruption is a research topic but not often in the context of family firms. The literature of family enterprises dealt with the influence of family ownership on firms’ non-compliance with corporate governance codes out of the socio-emotional wealth perspective or examined the relationship between family control and young entrepreneurial firms’ bribing behaviour around the globe. Another perspective offers the literature about the agency and stewardship theories and their influence on family firms. Agency and stewardship governance affects individual-level behaviour and firm-level performance in a distinct and combined way. In the business ethics literature a few interesting papers were found, that consider unethical work behaviour or corrupt acts in the context of organizations and family firms. In addition, the analysis of the publications demonstrates the importance of compliance management in all types of companies/SMEs and shows that companies which have integrated compliance management gain a competitive advantage over their competitors. We come to the conclusion that additional empirical research on compliance and corruption in family firms is needed.

THE INTANGIBLE CULTURAL HERITAGE IN SULUK WUJIL: SEMIOTICS ANALYSIS
Authors: Novan Setiawan Nugraha Deden
Published: November 2019

Cultural heritage is a legacy of the past reflect the identity of a group ethnic or nation. Cultural heritage contains not only traditional values but also belief systems. One of intangible cultural heritage is Suluk Wujil. Suluk Wujil begins with the journey of a young man named Wujil who tries to find information about the chosen religion to the deepest secret. During the ten years of his journey, Wujil has not found the true truth about the nature of divinity and the meaning of his existence in the universe even though he has studied various kinds of science and knowledge. This research is in the form of qualitative descriptive with Roland Barthes's semiotics as the main instrument for analyzing data. The identified sign system is interpreted in two stages of significance (language level and myth level). Oriented to the core myths of Sufism, the illustrated rules of Makrifatullah are divided into four categories; the introduction stage (a human being must escape in understanding one's own authenticity in order to reach the highest epistemology in the universe,, search plan (the depth of the heart of a human being is a sacred place where divine nature is buried as the greatest secret (sirru sirr), the practice of reaching Makrifatullah must be totality and continuity through words (qouli), deeds (fi'li), mind (aqli), and heart (qolbu), and reflection of application (awareness of tolerance among fellow creatures (habluminannas) as the result of perfect understanding of the reality of divinity (habluminallah).

Published: November 2019

The operating experience of the large-capacity vessels shafting illustrates a number of new technical problems, such as an increase in the number of accidents caused by damage to stern devices. A significant number of accidents associated with breakdowns of the propeller shafts due to exceeding the cyclic strength of their material, suggests the need for further study of the vi-brations of the shafting system. The creation of an experimental installation on the basis of the la-boratory of the ship shaft line of Astrakhan State Technical University provided experimental data under controlled test conditions. The design and operation principle of the experimental setup, which simulates the oscillations of a rotating shaft line model using various materials of shafts and bearings have been studied. The installation is a model of a ship shaft system, the shaft system

of which is driven by an asynchronous electric motor. The speed of the shaft system can be adjusted using a frequency converter. Measurement and registration of vibrations is carried out using

a hardware-software complex by the method of dynamic strain gauging. There have been shown the results of an experimental study of the parameters of transverse vibrations of a ship shaft model for various material of a stern bearing model and clearance in a stern device. The obtained dependences are represented by the Lagrange interpolation polynomial and response functions in the form

of a second-order polynomial. Verification of the compliance of the regression model of data variability was carried out using a multiple coefficient of determination. Bearing material and clearance in a stern device have a significant effect on the frequency of the onset of an unstable state of the installation shaft. The research results can be used in the calculation of transverse vibrations of ship shaft lines.

The paper considers the diesel engines as the hearts of the lifeboat power plants

of all types of vessels: sea, river and mixed navigation, according to the International Convention on the Protection of Human Life at Sea - SOLAS. In the Russian Federation there are two types

of engines produced for this purpose: 4-9.5/11 (“Kaspiy 30”) with vortex-chamber mixing and

4-9.5/11 (“Kaspiy 40”) with a combustion chamber in piston and volume-film mixing. The Kaspiy 40 engine is characterized by good starting properties and does not require additional acceleration of the launch. The Kaspiy 30 engine, due to the design of the combustion chamber, must be equipped with a fuel mixture heating device in the combustion chamber, which must work before the engine reaches a stable mode of operation. This device is glow plugs powered by a rechargeable battery and connected sequentially, so that failure of one plug entails the inoperability of the entire chain. If the rescue operation is necessary, the lifeboat engines must be started on deck without

a coolant (sea water) in the cooling system and must work for at least 10 - 15 minutes until the crew gets into the boat and the boat is launched, after which the cooling system will take the sea water. If the glow plug system fails, especially when the ambient temperature is low, the start of the engine in the prescribed time may not take place at all. There has been studied the effect of magnetic treatment of fuel before the launch and during the launch on the activation energy of fuel molecules and their reaction in the combustion without external heat

Published: November 2019

The paper highlights the operation processes at the terminals of the transport node, which, to a considerable extent, are defined by arrival different types of cargo. The cargo is usually delivered from the suppliers’ enterprises with the help of transport facilities (by train/motor transport). To plan the efficient functioning of the sea terminal there should be used the methods

of forecasting input cargo flows. It has been stated that most works devoted to forecasting traffic flows on cargo terminals are recommended to use information from the history (for which it is nec-essary to draw the arrays of well-known results of forecasting in different situation) based on the long-term analysis of the terminal operation. The above method of forecasting is of little use, when the supplier network and destinations of the cargo change frequently. A certain difficulty can pre-sent the choice of factors that define the situation at the sea terminal and the size of forecasted parameters of the cargo flow. There has been given an example of the practical forecasting of cargo arrival for handling at the sea terminal. The practical implementation of the formal dependence

of forecasting the cargo arrival for processing in the direction “coast-sea” at the marine terminal is presented in the sequence of four blocks: 1) the necessary values are calculated; 2) the arrived consignments are selected that have been sent on the same day and satisfy the columns of the matrix; 3) posterior probabilities for the columns of the matrix are calculated; 4) forecasting of consignments arrival is calculated. In the proposed universal method of forecasting the arrival of goods to the marine terminal in the transport hub in the coast-sea processing directions there is used not only statistic data on the duration of cargo transportation to the marine terminal, but also operational information on the arrival of individual consignments

Published: November 2019

The paper is focused on the problem of the service life of the dredger chain, which largely depends on the efficiency and reliability of the hinge joint, when a mineral abrasive gets into the structural gap resulting in rapid wear of the joint under high dynamic loads. There has been developed a science-based technology of repairing parts of the assembly, without reducing the resource, from cheap and accessible (non-deficient) materials, taking into account modern technical and economic requirements, on samples. Wear resistance of samples of friction pairs has been defined in terms of a chain operating model. The research method is based on comparing the wear rate of samples in a pair made of steel 110Mn13 (sleeve - pin), 110Mn13 and 38CrNi3M (sleeve - pin), according to the standard technologies and taken as a reference, with pairs made of steel 110Mn13, C45K, facing with wire SV08A, electrodes E50A – UONI 13/55 and E – 190Cr5Si7 – LEZ – T – 590 – NG after heat treatment, chemical and heat treatment, surface plastic deformation. Samples were tested in the water-abrasive environment with a load of 6615 N (675 kgf). The wear resistance parameters were determined as following: 1) reference pairs of steel 110Mn13 (bushing-pin) and 110Mn13 (bushing), 38CrNi3Mo (pin); 2) pairs of steel 110Mn13 (bushing) and facing with wire SV08A (pin); 3) pairs of steel 110Mn13 (bushing) and cladding with electrodes

E–190Cr5Si7–LEZ –T–590– NG (pin); 4) pairs of steel C45K (bushing) and cladding with

E –190Cr5Si7 – LEZ – T – 590 – NG electrodes (pin); 5) pairs of steel C45K (bushing) and clad-ding with E50A – UONI 13/55 electrodes (pin). A graph of dependence of the bushing and pin wear on the relations of initial hardness and structures of friction pair has been built. It is recom-mended to restore the pin with wear-resistant electrodes E – 190Cr5Si7 – LEZ – T – 590 – NG paired with 110Mn13 steel bushing with surface plastic deformation. The wear resistance of a pair, with a different combination of structures, does not depend on the ratio of hardness of Hsl / Hfin. The materials of the pair worn within the reference samples can be recommended for the operational tests.
Studying influence of designed trim in small fishing vessels with great hull fullness on their seaworthiness

Published: November 2019

The paper highlights the problem of the small trawlers with great block coefficient, despite their optimal architectural and constructive characteristics for fishing in the Baltic Sea. it has been stated that when the expected speeds of the vessel are reached, their towing resistance increases greatly and a significant trim appears on the bow. To clarify the reasons there have been carried out the additional studies of the relation between changes in the landing gear and the towing resistance of the vessel in different modes of movement in order to select the optimum trim for the vessel. The test program included towing tests of a ship model in the speed range 4-12 knots

of a full-scale ship with one displacement value and different initial trim values at the stern. It has been inferred that at the stage of designing small fishing vessels (up to 24 meters long) it is advisa-ble to limit the maximum speed to 11 knots, which corresponds to a Froude number ≈ 0.4. Further increase in the speed of the vessel will result in rising a residual resistance coefficient considerably, which will lead to a disproportionate increase in the required power. The residual resistance coeffi-cient of the hull is minimal, provided that the vessel moves at the calculated speed with an even keel, while the optimum angle of the initial trim makes 1.0-2.5 degrees aft. Improper longitudinal balance of small fishing vessels with a large completeness of contours can lead to an increase in re-sidual resistance of up to 30%. The experimental results can be applied to all small fishing vessels with similar block coefficients. It has been recommended to conduct the full-scale tests with differ-ent ship models having various block coefficients in order to define the dependence between the completeness of the vessel and the value of drawdown.

Authors: Бимбереков Павел , Bimberekov Pavel
Published: November 2019

The paper presents a comparison of the photographic material of the wave patterns resulted from the movement of a ship in situ and a model ship, as well as from two consecutive posts, their regularities being found through graphical processing. The possibility to find the fore imaginary source of Kelvin wave pattern forming the ship's wave system is given at a distance

of one wavelength before the top of the bow retaining wave. The equality of the length of trans-verse waves and divergent waves along the outer boundaries of the latter zone is fixed. It has been assumed that the intermediate waves generated between the main waves in the model ship and the posts are regular, imposition of wave patterns in a pair of consistently moving racks depending on the hit of the rear rack in the wave field of the first rack has been stated. Regularly occurring flows around moving posts are discussed. The bow and stern system of Kelvin waves in a ship wave sys-tem has been illustrated (the angle of the midpoint of diverging wave crests with the ship’s diamet-rical plane and the angle of diverging wave crests with the ship’s diametrical plane). The photo-graphs presented were taken in the experimental tank of Siberian State University of Water Transport (Novosibirsk State Academy of Water Transport) in 2006. A thin film naturally generat-ed on the water surface of the experimental tank and given a structure directed along the tank due to previous runs helped to visualize the distortion of the free water surface in better quality and to obtain clearly outlined contours in lighting.

Published: November 2019

The paper describes small-capacity irrigation evaporators that improve the performance of a refrigeration unit, as they exclude the release of liquid freon into the compressor suction pipe under sharp increasing of heat load or during ship rolling. The relevance of studying heat transfer at freons boiling in a moving film has been proved. The results and analysis of experimental data on average heat transfer coefficients are presented. The graph shows the dependence of the average heat transfer coefficients on the heat flux density at various irrigation densities. There are presented the results of special experiments determining the effect of irrigation density on heat transfer. It has been stated that the effect of pressure or saturation temperature in the modes of evaporation and developed boiling manifests itself in different ways. With developed boiling, the beam pitch does not have a significant effect on heat transfer. The experiments were carried out on two stands: small-row and multi-row. The pipes were heated with an internal electric heater. It has been inferred that heat transfer in the film is more intense than in volume, therefore, smooth steel pipes can be used in irrigation evaporators instead of finned copper tubes, which are used in flooded devices. The boiling process in a film can be described by equations valid for a large volume, taking into account quantitative differences. The values of a constant coefficient and the criteria exponents are given; the similarity equation for the regime of developed bubble boiling of freons is derived. The calculated dependencies can be applied in evaluating the operation of irrigation evaporators of ship refrigeration units.

This essay traces a parallel between the series “Museu do Homem Diagonal,” created in 2013 by Brazilian artist Renata Lucas in Rio de Janeiro, and Conical Intersect, created in 1975 by American artist Gordon Matta-Clark in Paris. Despite their different contexts, both artists responded to the ongoing urban transformations through the creation of a dialogue between their work, the changing surroundings, and the city dwellers. By analyzing how the artists evoked displacement and memory through urban interventions, this essay highlights the role of art in questioning the transitory nature of cities and its ability to imagine alternative scenarios.

Published: November 2019

The Agrifood Industry is the largest Portuguese Industry, constituted mainly by micro, small and medium-sized enterprises (SMEs). It is noted that more than any other type of organization SMEs have their own speci?cities that make it particularly appropriate to develop tools to facilitate communication and knowledge sharing for employers and workers. To this extent, identifying critical success factors is the key to increase SMEs productivity. Likewise, Occupational Safety and Health (OSH) in SMEs have their own characteristics, which dif?cult the prevention strategies implementation and aggravate the problematic of work accidents. This study analyses a ?eldwork in 60 food processing companies in Portugal, related to the dairy, meat processing, bakery and horticultural subsectors. The analysis of the results allowed to identify that, at the national and regional level, the main failures are concerned with (1) lack of risk assessments regarding occupational noise, lighting, thermal environment and vibrations; (2) safety signaling, the circulation ways are not identi?ed with appropriate safety colors; (3) general lighting, with too many shade areas and finally (4) complementary presence of associated risks to falls at the same level, falling of objects, thermal burns, the use of machines and equipment, ?re, mechanical, ergonomic hazards and incorrect body postures. This study assesses the most relevant occupational health and safety risks in the Portuguese food processing industry to contribute to the improvement of OSH management and prevention of work accidents.

El propósito de este trabajo es aproximarnos al examen de cómo las estadísticas se fueron convirtiendo en un insumo básico de la hacienda pública, y cómo se configuraron en una forma particular de lenguaje, en el que a través de las cifras oficiales se indicaba su comportamiento. Estas estadísticas pretendieron medir la riqueza nacional, su proceso de crecimiento, para así poder compararla con otros países, así como hacer predecible su comportamiento. Cabe señalar que el desarrollo de la hacienda pública durante el siglo XIX implicó la formación de nuevas instituciones para su desempeño, y para todas ellas la formalización estadística fue prioritaria, y ello no sólo era una cuestión técnica sino también política.
El paisaje urbano de las ciudades pequeñas. La plaza central de Hunucmá Yucatán
Authors: Sánchez Rosas Raquel Concepción , Baños Ramírez Othón
Published: November 2019

La plaza central de las ciudades pequeñas de Yucatán es un espacio público abierto que cumple varias funciones urbanísticas. A pesar de su modesta apariencia se trata de un lugar complejo cuyos componentes tangibles e intangibles están relacionados de manera subjetiva. Constituye un paisaje urbano emblemático. Para su comprensión se analizan los edificios más sobresalientes de sus alrededores, se describe la forma cotidiana que es utilizada para la convivencia y el paseo. Así como los eventos más significativos de la localidad, con raíces que se remontan al periodo colonial, que ahí tienen lugar. Fueron detectadas algunas amenazas de la modernidad que minan algunas de sus capacidades históricamente heredadas como la simbólica e identitaria. Ante lo cual, se sugiere que un rescate de la plaza central desde una perspectiva paisajística contribuiría al fortalecimiento de la identidad comunitaria, entre otras ventajas.
Wykorzystanie technologii teleinformatycznej w sektorze publicznym jako czynnik wpływający na funkcjonowanie przedsiębiorstw
Authors: Kasprowicz Paweł
Published: November 2019

Rosnąca rola technologii teleinformatycznych (ang. ICT – Information and Communication Technologies) nie pozostaje bez wpływu na środowisko społeczno-ekonomiczne. Upowszechnienie się na­rzędzi informatycznych wpływa na oczekiwania podmiotów gospodarczych dotyczące sposobu obsługi przez organy administracji publicznej, natomiast stosowane przez nie rozwiązania informatyczne i ich wykorzytanie stwarzają potencjał do poprawy relacji na linii przedsiębiorstwa–administracja publiczna, a także do zwiększenia ich efektywności. Brak działań organów publicznych w tym zakresie oraz niedostosowanie ich struktury, organizacji i sposobu funkcjonowania do zmieniających się standardów podmiotów prywatnych stwarzają zagrożenie, że pojawią się dodatkowe koszty funkcjonowania przedsiębiorstw oraz zwiększą się koszty już istniejące. Ścisła i precyzyjna analiza tych zagadnień jest utrudniona z powodu dużego zróżnico­wania rozpatrywanych zjawisk. Celem pracy jest próba rozwiązania tego problemu oraz zaproponowanie po­dejścia badawczego pozwalającego na objęcie zjawisk spójną analizą. Autor proponuje zastosowanie meto­dyki i terminologii nowej ekonomii instytucjonalnej, czyli wykorzystanie teorii kosztów transakcyjnych oraz instytucji. Oddziaływanie zróżnicowanych czynników instytucjonalnych zostaje sprowadzone do analizy ich wpływu na koszty transakcyjne, koszty te mogą natomiast zostać opisane z użyciem narzędzi matematycz­nych i wykorzystane do dalszej analizy.
Przemysłowe wykorzystanie energii geotermalnej w Polsce na przykładzie geotermalnego zakładu ciepłowniczego w Bańskiej Niżnej
Authors: Sala Krzysztof
Published: November 2019

Energetyka geotermalna może stanowić interesujące pod wieloma względami źródło energii odnawialnej. Wśród jej wielu rozmaitych zastosowań na uwagę zasługuje wykorzystanie przemysłowe. Celem i przedmiotem artykułu było ukazanie znaczenia odnawialnego źródła energii, jakim jest energia geotermalna, w wykorzystaniu przemysłowym na terenie Polski. Praca powstała na podstawie dostępnej zwartej literatury książkowej, danych statystycznych oraz publikacji i wiadomości netograficznych. W artykule ukazano zasady funkcjonowania energetyki geotermalnej, jej rolę i znaczenie dla gospodarek na świecie i w Polsce. Wymieniono te kraje, które w największym stopniu wykorzystują praktycznie instalacje geotermiczne. Dokonano zestawienia przesłanek i barier wynikających z wykorzystywania geotermiki. Szczególną rolę w niniejszej publikacji poświęcono przemysłowemu wykorzystywaniu energetyki geotermalnej w Polsce. Jako przykład wybrano pierwszy zakład geotermalny na terenie naszego kraju – w miejscowości Bańska Niżna. Zaprezentowane dane zostały zilustrowane przy pomocy tabel i wykresów. Metodą badawczą wykorzystaną w artykule była analiza danych zastanych oraz krytyka piśmiennicza. Tezą, jaką postawiono w publikacji, jest założenie, że energetyka geotermalna może stanowić ważne źródło energii w wykorzystaniu przemysłowym. Należy jednak brać pod uwagę zarówno jej zalety, jak i mankamenty. Wyniki analizy danych zastanych pozytywnie zweryfikowały postawioną tezę.
Rozmieszczenie usług jako podstawa rozpoznawania ośrodków podregionalnych w Polsce i ich hierarchii
Authors: Sołtys Jacek , Dorocki Sławomir
Published: November 2019

Ośrodki podregionalne definiowane są jako miasta, w których skoncentrowane są takie usługi, które w Polsce mogą występować w kilku miastach województwa, ale nie w każdym mieście powiatowym. Usługi zawsze miały tendencję do koncentracji, tworząc ośrodki różnych poziomów w hierarchicznej sieci osadniczej. Celem prezentowanych badań było: (1) określenie usług typowych dla poziomu podregionalnego; (2) rozpoznanie koncentracji tych usług, tworzonych przez nie ośrodków i ich rozmieszczenia oraz (3) ocena, w jakim stopniu występują prawidłowości hierarchicznego modelu lokalizacji usług na poziomie podregionalnym w Polsce. Takie usługi w Polsce, poza obszarami metropolitalnymi i miastami wojewódzkimi, były przedmiotem badań. Za usługi typowe, definiujące ośrodki podregionalne, uznano: sądy okręgowe, szpitale wielospecjalistyczne, wyższe uczelnie i kina multipleksowe. Zbadano metodą klasyfikacji zróżnicowanie ośrodków, a poprzez analizę kartograficzną – ich rozmieszczenie. Badania, będące kontynuacją badań z 2015 roku, uwzględniające aktualniejsze dane i szerszy zakres usług, wykazały 23 ośrodki podregionalne pełne i 47 niepełnych, w których zestawy usług tworzą różne kombinacje, z dwoma dominującymi. Jako prawidłowość stwierdzono dużą koncentrację usług. Rozmieszczenie ośrodków jest nierównomierne, prawdopodobnie z powodu zróżnicowania gęstości zaludnienia.

Educación bilingüe (español-inglés) en tres instituciones educativas públicas del Quindío, Colombia: estudio de caso
Authors: Galindo Angelmiro , Moreno Lina María
Published: November 2019

Esta investigación cualitativa describe la educación bilingüe en tres instituciones educativas públicas (IE) del Quindío, Colombia. Las fuentes de recolección de datos fueron: (1) Entrevista semiestructurada, (2) Análisis documental y (3) Observación. Los resultados indicaron lo siguiente: Las categorías Políticas institucionales de educación bilingüe, Prácticas de educación bilingüe, Prácticas interculturales y Modelo pedagógico convencional mostraron la necesidad de replantear el modelo pedagógico. La categoría Formación docente indicó que las actividades de formación docente tenían como sustento el modelo de entrenamiento del docente. La categoría Desarrollo de competencias en inglés mostró una relación directa con las categorías Políticas institucionales de educación bilingüe y Prácticas de educación bilingüe, dado que los conceptos de bilingüismo y competencia comunicativa bilingüe fueron reducidos al concepto de competencia alcanzada en inglés. La categoría Enseñanza mediada por las TIC indicó la integración de las TIC en la formación bilingüe en las tres IE. La categoría Recursos para el desarrollo bilingüe reveló que los docentes de las tres IE estaban formados en aspectos generales del ejercicio de la docencia. Se concluyó recomendar, a las tres IE, el tránsito de la educación bilingüe y bicultural hacia la educación bilingüe intercultural crítica e, igualmente, promocionar el desarrollo docente en pedagogía de la educación bilingüe e intercultural.
Producción de ensayos y artículos de divulgación en asignaturas de lengua castellana: Implicaciones en la formación del profesorado
Authors: Uribe Álvarez Graciela , Parra Hoyos Edwin Leandro , Zambrano-Valencia Juan David
Published: November 2019

Esta investigación se centra en la pregunta: ¿Cómo optimizar los procesos de enseñanza y aprendizaje de la competencia escrita de los estudiantes de la Licenciatura en Literatura y Lengua Castellana, alrededor de géneros discursivos propios de los textos argumentativo y expositivo-explicativo? Para responderla, optamos por un enfoque cualitativo apoyado en el método investigación-acción. Efectuamos intervenciones en dos grupos de estudiantes de quinto y noveno semestre. Ambos grupos tienen en común que se forman para el ejercicio profesional en la enseñanza básica y media. Concluimos que los docentes en formación logran planear, ejecutar y evaluar textos eficaces para sus entornos específicos de aula, y generamos un Recurso Educativo Digital Abierto-REDA (Expoargumentar) que ayudará a los futuros docentes a diseñar propuestas de intervención en función del desarrollo de las competencias escriturales.
Vers une perspective plurilingue et interculturelle dans la formation en langues étrangères à des étudiants indigènes en contexte universitaire
Authors: Arismendi Gómez Fabio Alberto , Ramírez Jiménez Denis
Published: November 2019

Dans cet article, nous étudions les implications d’avoir des étudiants indigènes dans les programmes de formation au niveau universitaire. Cette discussion surgit à partir des résultats d’une étude de cas menée dans un programme de licence en langues étrangères (anglais et français) dans une université colombienne. Huit étudiants en provenance de différentes communautés du pays y ont participé. La collecte de données s’est effectuée principalement lors des entretiens individuels et collectifs menés auprès des étudiants ainsi que des entretiens en groupe focalisé (focus group) menés auprès de leurs enseignants. Les résultats suggèrent des implications dans trois domaines : au niveau institutionnel, au niveau pédagogique et didactique, et au niveau estudiantin. Une perspective d’éducation plurilingue et interculturelle peut éclairer les différentes actions qui pourraient se mettre en œuvre dans chacun de ces domaines, afin de contribuer à une éducation en langues étrangères plus juste et équitable.
