Can Central Bank Survive the Green Banking Revolution?
Authors: Nisha Nabila
Published: May 2020

Various eco-friendly services, broadly known as green banking, are now part of most banking activities. These services relate to banking transactions conducted less on paper and more over an electronic platform. This new form of technology is being used with increasing frequency in low carbon-emitting countries like Bangladesh to promote environmental sustainability. Despite the central bank playing a prominent role in this vision development, surprisingly the level of green banking adoption is still low among its employees. This study thus aims to identify factors that affect bank employee use of green banking, by integrating management support, customer and competitor pressure with a technology acceptance model. Findings indicate that the perceived ease of use influences perceived usefulness, whose impact is then observed upon actual use. It is also quite lucid that both management support and customer pressure have substantial impact on green banking adoption for central bank employees.

Published: May 2020

Melissopalynology, or pollen analysis of honey, is one of the areas that benefited greatly from image processing and analysis techniques, where melissopalynology is the science that studies the pollen contained in honey, using a microscopic examination. Nowadays, developing an automatic classification system for pollen identification presents a challenge. This article presents a metaheuristic for image segmentation to detect pollen grains in images. It is a swarm intelligence technique inspired from grey wolf hunting behavior in nature, centered around respecting the hierarchy of a pack. It was tested on a set of microscopic images of pollen grains. To evaluate pollen detection, we represented the detected pollen grains using two methods, grey-level based representations where we kept grey value of each pixel, and a binary mask-based technique, where a pixel could have only two values (1 or 0). Then, we used a convolutional neural network (CNN) technique for image classification to predict the specie of each pollen. The proposed system was tested on a set of microscopic images of pollen grains. The obtained performance measures of the system proved that the system is very successful.
The Efficiency of Pt-Doped Titania Pillared Clay Membranes for the Treatment of Real Textile Wastewater: A Case Study
Authors: Choudhury Tanushree
Published: May 2020

Titania pillared clay membranes exhibit unique charge characteristics which are dependent on the solution pH. Doping of such membranes with precious metal like Pt induces a positive charge on the surface of the membranes, thus increasing its resistance against fouling. X-ray Diffraction (XRD) and Fourier Transform Infra-Red Spectroscopy (FT-IR) confirm the complete intercalation of anatase titania in the interlayer spaces of Montmorillonite in the present work. These membranes efficiently removed 83% of the dye from the real textile effluent in a one filtration cycle.

Published: May 2020

Due to the increasing of the price of different materials and resource saving it is very promising to develop technology of creation cheap coatings with specified properties. We developed a diffusion-doped powder based on austenitic steels for producing plasma-sprayed coatings. In comparison with Ni-based powders our materials have better adhesion, they are cheaper, they have better mechanical machinability, it is possible to produce coatings with required properties. In our work, the features of diffusion doping of microparticles of powder, the behavior of the powder in the plasma jet were studied. The significant decreasing of porosity, increasing of adhesion of the plasma-sprayed coatings after laser processing were marked. The substantial increase of wear-resistance in 2,5-3,0 times in comparison with untreated coatings when working in conditions of abrasive wear and atmospheric precipitation was revealed.
Operationally Ready Advancements in Oil Free Corrosion Control for Advanced Materials
Authors: Donaldson Keith W. , Kajiyama Akihiro
Published: May 2020

Operationally ready is a key component to effective management of equipment, spares and systems through manufacturing, shipment and transport, meaning that products are impacted by how they stored, shipped and staged. That means no rust, no degradation and the ability to utilize the equipment or parts quickly, with no cleaning or additional work required. Significant advancements have been made in oil free, volatile free anti-corrosion protection to aid this. These advancements are in the form of plastics, laminates, canvas, woven products and shrink films that can be used to provide long term stable packaging that can be used both as short term, one-time use, multiple use applications or even used to create portable storage shelters. These materials will also help stabilize and help protect metals as well as non-metallic components and materials such as items that can swell, gaskets, fabric and rubber components, against degradation – this is critical since many systems are combination of materials, no longer just single material construction. These developments in oil free, volatile free packaging have been successfully incorporated into automotive applications with short term and long-term protection being available from the same packaging. Additionally, information on accelerated testing on already environmentally stressed items will be reviewed and solutions presented to their protection schemes as well.

Authors: Kusano Yukihiro , Cederløf Daan Jonas Hottentot , Fæster Søren
Published: May 2020

Bundles or fabrics of sized glass fibres were treated by a dielectric barrier discharge plasma in a He/CF4 gas mixture at atmospheric pressure with and without ultrasonic irradiation. The plasma treatment introduced fluorine both inside and outside of the fibre bundle, decreasing wetting of glycerol. Ultrasonic irradiation markedly increased the fluorine content as well as the silicon, calcium, and aluminium contents, indicating simultaneous fluorination and preferential etching of organic components. It is indicated that plasma treatment in a He/CF4 gas mixture can be used for controlling the surface properties of glass fibre bundles, and that ultrasonic irradiation can enhance functionalization and etching.

Authors: Hansuebsai Aran , Nawakitwong Samatcha
Published: May 2020

This research analyzed the printability of compostable films commercialized in the Thai market such as PLA/PBAT and PBAT/starch; and to comply with EN 13432 standard by using flexographic water based ink. A narrow web flexographic printing press was set up and opperated. Print quality parameters such as optical density, tone reproduction, print contrast and print uniformity were investigated. Results showed that these compostable films were hydrophobic in nature, in combination with fracture and voids of substrates’ surface. Even the substrates could be printed relatively well but showed poor ink adhesion. Surface treatment, therefore, was necessary, but having limitation. Anilox line screen 700 lpi and printing speed at 30 m/min were preferable to achieve the optimum tone reproduction and print contrast. This was based on the image resolution of 133 lpi and corona dosage at 500 watt-min/m2. Images of printed samples from SEM and SPM indicated that the fracture surface and void of films could lead to decrease their printability. It was found that starch blend gave better results as being a filler of the surface roughness of the substrate..
Real-Time and In Situ Monitoring of FRP by Rayleigh Scattering-Based Distributed Sensing
Authors: Kosaka Tatsuro
Published: May 2020

In-situ monitoring method of FRP (Fiber Reinforced Plastics) by built-in sensors is a key technology for developing future and high-reliable composite structures. The Rayleigh scattering-based distributed optical fiber sensor has high spatial resolution of 1mm and good embeddability into FRP and then it can be considered that the sensor is very suitable to in-situ monitoring of FRP. In the present paper, process monitoring and damage identification of FRP were conducted. In the process monitoring, flow-front of silicon oil impregnating into glass textile during VaRTM (Vacuum-assisted Resin Transfer Molding) process was measured. Comparing to visual observation results, it appeared that the maximum slope position of strain distribution showed flow-front position. In the health monitoring, damage identification of cross-ply GFRP laminates with delamination by the attached distribution optical fiber sensors was carried on. From the results, it was found that the strain varied largely on the delaminated section and then the delamination was detectable from the surface strain distribution measured by the optical fiber sensor.

Published: May 2020

Acetylcholine (ACh) is a main neurotransmitter functioning in smooth muscle and cardiovascular system control. It also plays a key role in memory and learning. While excessive acetylcholine level results in decreased heart rates, depleted level of acetylcholine in human brains can lead to Alzheimer disease. Therefore, detection of acetylcholine is clinically vital. This study aimed at examining potential usage of titanium dioxide (TiO2) doped with 2.5 mol% Zn as electrochemical sensors for acetylcholine detection. Zn-doped TiO2 powder was synthesized by a solution combustion technique. Phase identification, microstructural examination, as well as electrocatalytic activity evaluation of the synthesized powder were conducted. The synthesized powder showed anatase phase with fine particle sizes ranging from 9.3 to 11.4 nanometers on average. Specific surface area of 75.48 m2/g was observed. Electrocatalytic activities of the powder in cholin acetate solutions with concentrations ranging from 0.05 to 0.1 μM and 1 to 10 μM were evaluated via cyclic voltammetry technique. At applied voltage of 0.05 V, peak currents corresponding to oxidation reactions between ACh and Zn-doped TiO2 were detected. Sensitivity values of 3.13x10-4 and 1.32 μA/(μMmm2), which is in an acceptable range, were evident.
Study of Impact Velocity on Residual Stress and Surface Hardness of SKD11 in Shot Peening Process
Authors: Chupong Pudsadee , Tuchinda Karuna
Published: May 2020

Shot peening process could create compressive residual stress and increase surface hardness and hence also used to improve material surface properties in case thermal effect is to be avoided. The shot peening process parameters such as pressure which result in different shot impact velocity could affect the compressive residual stress distribution which results in different post-process material properties. The ability to understand and predict the effect of process parameters on stress distribution could be very useful to control and obtain material properties as required. In this work, a shot peening process commercially available locally was investigated. The residual stress distribution after shot peening of SKD11 was studied using the finite element (FE) technique. A single shot impact was simulated. A maximum velocity with a miximum impact angle was assumed. The computational predictions showed higher compressive residual stress developed with increasing shot velocity as expected due to higher impact energy. However, experimental results suggested that the process arrangement and machine control highly affect the properties of the material after process. The compressive residual stress and surface hardness obtained experimentally was almost unchanged with an increase in pressure from 0.35MPa to 0.6MPa. It was found that, due to machine arrangement, an increase in impact velocity at higher pressure was relatively small and did not observed in all effected area due to fixed arrangement of nozzle and samples. Hence, research results suggested that a detail computational methodology including the effect of unevent impact velocity and impact angle should be employed to increase the predictive ability of the FE model. The current work could be extended to include such effects with no major difficulty to develop useful information for the design of shot peening process for any specific machine and arrangement.

Authors: Saithongkum Nathathai , Tuchinda Karuna
Published: May 2020

Carbon fiber reinforced polymer is mostly used to improve the performance of polymer-based component. Nevertheless, composite material properties depend on many factors such as fiber direction, length of fiber, matrix material and manufacturing process. This work aims to study the effect of fiber length and orientation on material stress-strain relationship. Short carbon fiber length (0.2 and 0.5 mm) reinforced with phenolic resin and long carbon fiber reinforced with commercial matrix material were studied. Long carbon fiber showed higher tensile strength than short carbon fiber with longitudinal direction, whereas slightly difference was observed for transverse direction. The printing path significantly affects failure location as area with lower fiber density exhibit lower local strength. Finite element simulation of the tensile test was carried out with the homogeneous material model which suggested that it could accurately predict the load capacity of printed composite. The bending strength was then computationally predicted. It was found that 0 degree offered higher bending load capacity than 90 degree orientation for all carbon fiber length with smaller difference with shorter fiber. Almost insignificant effect of fiber orientation was observed for 0.2 mm. fiber length.
Octahedral Layered Birnessite (OL) Supported Ag Catalysts: Characterization and Catalytic Oxidation of CO
Authors: Chen Meng Yue , Dong Ning , Ye Qing , Fu Zhi Dan
Published: May 2020

Octahedral layered birnessite (OL) was synthesized by redox method, and OL supported Ag catalysts (xAg/OL, x = 0.1wt%, 0.2wt%, 0.3wt%, 0.5wt%) were prepared by ion exchange method. Then catalysts were characterized by XRD, SEM, BET, H2-TPR, TG, O2-TPD and in-situ DRIFTS, while the catalytic activity of CO was evaluated. Among xAg/OL samples, the 0.3Ag/OL exhibited the best catalytic activity for CO oxidation (T50 = 105 oC and T90 = 135 oC). The results show that the chemical adsorption of oxygen, the low-temperature reducibility and the strong interaction between the Ag species and OL are related to the excellent catalytic activity of xAg/OL. The reaction mechanism was studied by in-situ DRIFTS. First, O2 was adsorbed and activated on the oxygen vacancies of xAg/OL, then formed oxygen free radical attacked the adsorbed CO and produced CO2, subsequently CO2 desorbed from the catalyst surface. Oxygen vacancies was supplemented by gas O2, thus circulating.

Published: May 2020

Providing enough water in farming has become a challenge in the Philippines due to insufficient irrigation and escalating drought conditions, thereby decreasing agricultural productivity. The impact of this problem can be lessened through efficient water usage: by reducing water wastage in runoff or evaporation and improving soil water retention. Hydrogels can be used for this purpose due to their water absorption capabilities. In this study, a novel, biodegradable agricultural hydrogel was developed from κ-carrageenan, sodium alginate and carboxymethyl cellulose, crosslinked with Ca2+ and K+ ions. Scanning electron microscopy analysis confirmed the successful crosslinking while swelling tests revealed them as superabsorbent hydrogels, with maximum absorption reaching 2000%. Soil amended with 2% (w/w) hydrogel showed reduced water-depletion rate and improved field capacity by a maximum of 17.6% and 17.4%, respectively. Fertilizer release test also showed the potential of these hydrogels as fertilizer carriers.

Physical simulation of steel Mn3Ni1CrMo continuous cooling with different speeds from austenitic state was performed using GLEEBLE 3500 complex. The phase transformations are analyzed and the effect of the cooling rate on the structure and hardness is investigated. A continuous cooling transformation diagram of the undercooled austenite decomposition is constructed. It was concluded that it is possible to reduce the hardness of the hot-rolled billet by reducing the cooling rate compared to the existing in the processing at the STELMOR line of PJSC “MMK”, and this will eliminate the heat treatment of welding wire on the hardware processing.

Technical note for post processing of jugular venous pulse, central venous pressure and velocity trace
Authors: Tavoni Valentina
Published: May 2020

In this paper an original reasoning about the post processing elaboration of medical studies is presented. The aim is to suggest a method to extrapolate numerical information from clinical images. The here described elaboration is referred to ultrasound examination of internal jugular veins and central venous pressure (CVP) measures. Firstly, the operator has to collect clinical images following precise indications, then specific techniques are applied to analyze the stored data and extrapolate quantifiable measures. Analyzing the studies with ImageJ software, jugular venous pulse, velocity, CVP and electrocardiogram traces can be drown in detail. Then, significant details can be highlighted using Matlab software. Finally, using R software, the traces can be cropped, aligned and synchronized together. The obtained results allow the operator to compare different kinds of traces of the same subject, or the same type of traces between a particular group of subjects. Before using these contents, everyone is invited to verify the accuracy of assumptions, calculations and conclusions.

Published: May 2020

For investigation of biofouling characteristics of marine microalgae on lithium manganese oxide disk (LD), which is manufactured for recovery of mineral resources from seawater, we carried out an exposing test for LD at Okgye, East Sea, Korea. The amount and species composition of the attached microalgae on the LD surfaces were determined based on the exposing period and season. The immersion test was conducted for 7 d, 14 d and 21 d for each of the three different seasons of May, August and October. The number of microalgae attached to the LD is dependent in season and exposing duration. In May and October, the microalgae adhered approximately 4,000 cells/cm2 after 7 d and after 14 d, more than 2-fold were attached that exceeding 10,000 cells/cm2 . In spring and summer, centric diatom, Guinardia sp. and Cyclotella sp. were dominated in seawater, and they predominantly adherent in short exposure periods of within 7 d. However, dominant adherent species were succeeded to Cylindrotheca sp., pennate diatom, as longer exposure times. The microalgae morphology, which favored attachment was also a major cause of prolonged fouling upon exposure of LD surface.
Application of a multiple criteria analysis for the selection of appropriate radical based processes in treatment of car wash wastewater
Authors: DURNA Elif , GENÇ Nevim
Published: May 2020

In this study, the treatment of car wash wastewater was investigated by radical based hybrid/combined processes. Proposed processes, (Microwave (MW) + persulfate (PS) + Electrocoagulation (EC)), (ozone (O3) + PS + EC) and (MW + PS + O3), were optimized with Taguchi orthogonal array technique for maximum COD removal. The COD removal under optimum conditions was obtained to be 84%, 64.9% and 61.4%, for (MW + PS+ EC), (O3 + PS+ EC) and (MW + PS+ O3) processes, respectively. Operating costs for (MW + PS + EC), (O3 + PS + EC) and (MW + PS + O3) processes have been calculated as 0.2614, 0.1335 and 0.2653 €/L wastewater under optimum operating conditions. Pareto analysis showed that MW time and PS dose are very effective parameters but especially ozone related parameters have no significant effect on COD removal. Processes were evaluated with the PROMETHEE approach in terms of treatment efficiency, operating cost, sludge formation, and preferability criteria to determine the most suitable among the three alternative processes. As a result, the preference order of the processes for the treatment of car wash wastewater with radical based treatment processes was found as (MW + EC + PS) > (MW + O3 + PS) > (O3 + EC + PS).

As contribuições para a Nova História Política de Jürgen Habermas
Authors: Rosa Juliana Cristina da
Published: May 2020

Este artigo tem como objetivo analisar a contribuição das reflexões de Jürgen Habermas para a Nova História Política, sobretudo no que diz respeito à relação entre Dignidade Humana e Direitos Humanos, que para o autor é uma dobradiça conceitual capaz de garantir a concretização do discurso jurídico, onde a razão instrumental é utilizada para a formulação da consciência das gentes sobre seus direitos a serem garantidos pelo Estado democrático. O autor acredita que existe possibilidade de emancipação por meio desse caminho atravessado pela noção moral de dignidade humana, que “uma e a mesma em todo lugar” garantirá a indivisibilidade dos direitos humanos. Por fim, o artigo reporta às preocupações tanto de Habermas como de Hobsbawm em relação ao mau uso dos direitos humanos como discurso legitimador de ações de intervenção e imperialismo praticado, sobretudo, pelos Estados Unidos.

Meu lugar de pertencimento na pesquisa junto da população em situação de rua é um lugar que está no coletivo, não é meu, é deles. E nesse lugar onde pesquisa e vida não se separam o esforço é o de compreender, por exemplo, como se constitui uma ética da rua. Como se constituem as comunidades com traços particulares de bando e nomadismo. Junto dessa população percebemos, por exemplo, o aprofundamento dos laços sociais que criam pertencimentos e afetos e que revela uma população ativista e rebelde, que em face do abandono, tem como estratégia de defesa e de luta, o 'bando' que somado à afetividade, trazem à tona comunidades nascentes, comunidades em Devir. Estas comunidades mobilizam espaços, temporalidades, fatos e artefatos sociais e da cultura, de maneira a subverter o desejo de pólis e consagrar-se ao desejo de Plaza (praça). O desejo de plaza é o desejo de rua, aquele que se constitui na “inexpropriação”. O que é irredutível a essa população, o que lhes é inexpugnável, é justamente não apenas a contingência da rua, mas o seu desejo, tanto a amparo como a r-existência. Essa ambiguidade, e não apenas essa, forja em grande medida o sentido da comunidade que vem, essas potências ensaiam as condições de possibilidade de uma política da rua, de uma vida comum, no sentido de uma vida compartilhada, isto é o mesmo que a utopia de uma comunidade nascente e de uma comunidade que ainda está vindo.

Na današnjem prostoru Republike Hrvatske (RH) na srednjovjekovnim dalmatinskim otocima i u gradovima već od 13. stoljeća postoje zakonski propisi (statuti) koji reguliraju život zajednice, kao i odnos ljudi prema životinjama. U 18. stoljeću kako u Europi tako i na prostorima današnje RH, zarazne bolesti domaćih životinja desetkovale su stočni fond, posebno u govedarstvu. Uz goveđu kugu, bedrenica, metiljavost, bjesnoća, slinavka i šap, sakagija i druge bolesti stvarale su velike probleme stočarstvu koje je bilo važan preduvjet sigurnog opstanka ljudskih zajednica. Od 1770. godine liječnicima je, uz liječenje ljudi, bila obveza i suzbijanje zaraznih bolesti domaćih životinja. U suzbijanju zaraznih bolesti glavnu je ulogu imao podžupan, a u to doba suci su bili upravni činovnici. Stoga su kod pojave zaraznih bolesti domaćih životinja na teren išli veliki i mali sudac, a uz njih je obvezno bio prisutan i liječnik ili kirurg. Od 1771. godine u kotarevima je postavljen komesar, koji je išao na teren i izvješćivao sanitetsku komisiju. Za pojedine zarazne bolesti domaćih životinja upotrebljavali su se nazivi na latinskom jeziku: Lues animalium, Lues pecoris, Lues mali, Lues pecoris grassanti, Pulmonum exsccationis, Contagion, Morbus bovi, Animalium infectionem, Vulkgo metily i drugi, ali najčešće na njemačkom jeziku Viehseuche.
Geographic distribution and spatial attributes of African tulip tree forests in north-central Puerto Rico: Implications forsocial-ecological resilience
Authors: Abelleira-Martínez Oscar J.
Published: May 2020

Agricultural abandonment resulted in the expansion of forests dominated by invasive tree species that were introduced throughout Puerto Rico. These novel forests are increasingly common worldwide but little is known about the drivers and consequences of their expansion. This study describes the geographic distribution and spatial attributes of novel forests dominated by the African tulip tree, Spathodea campanuata Beauv., in north-central Puerto Rico. I used aerial photography to map Spathodea forests, determined their distribution by geological substrate, soil type and previous history, and estimated the area and perimeter to area ratio (P/A) of each patch. The 443 mapped Spathodea forests covered 0.7% of the region, ranged from 0.03 to 9.1 ha (mean=0.5, S.E.=0.03) in area, and from 0.03 to 0.3 m/m2 (mean=0.09, S.E.=0.0002) in P/A. Spathodea forests were more frequent on lands previously used for sugarcane, which are typically on fertile Mollisols on alluvial substrate. Half the Spathodea forests were over 30 years old and those on former sun coffee farms on volcanic extrusive substrate had larger area and lower P/A. Novel Spathodea forests rehabilitate agricultural lands, increase spatial connectivity and create favorable conditions for agroforestry and species restoration interventions, representing an asset for social-ecological resilience to climate change and socio-economic development.
Growth comparison between wild type and slick-haired Puerto Rican Holstein heifers
Authors: Sánchez-Rodríguez Héctor L.
Published: May 2020

The present study compared the monthly body weight (BW) of 14 wild type (WT) and 11 slick-haired (SLICK) Puerto Rican Holstein heifers from four to 34 months of age at the Agricultural Experiment Station in Lajas, Puerto Rico. Data were analyzed by the GLIMMIX, GLM and REG Procedures in SAS. Hair coat type and age interacted to affect BW (P=0.0005). However, no differences in BW were observed between WT and SLICK heifers (overall mean BW of 279.33±5.78 and 275.06±6.91 kg, respectively; P=0.3182). From four to 34 months, BW increased in both the WT (93.52±11.42 to 446.35±28.27 kg; P<0.0001) and the SLICK heifers (85.69±9.97 to 381.37±35.81 kg; P<0.0001). The interaction observed between hair coat type and age could be the result of different growth trends, as WT heifers presented a linear curve (BW = 12.28 age + 54.41; R2=0.88; P<0.0001); while their SLICK counterparts showed a quadratic regression (BW = −0.32 age2 + 22.75 age + 6.24; R2=0.74; P<0.0001) between BW and age. These results suggest that SLICK heifers may reach maturity at an earlier age and with less BW. Future studies should evaluate if such differences affect the efficiency and productivity of these animals at maturity.
Revisión histórica y científica sobre el desarrollo de la ganadería de leche en Puerto Rico con énfasis en el ganado pelón
Authors: Sánchez-Rodríguez Héctor L.
Published: May 2020

Antes de la llegada de los conquistadores españoles, en el Nuevo Mundo no existían los bovinos domésticos. No fue hasta el 1493 que se introdujo por primera vez ganado proveniente de España a este territorio. Tras su adaptación y subsecuente reproducción mayormente por selección natural durante varios siglos, de este ganado ibérico se desarrolló nuestro ganado Criollo. Estos animales, de pequeño tamaño corporal, pelaje corto y alta adaptabilidad al trópico, formaron la base de nuestra ganadería durante cuatro siglos de gobierno español y durante los primeros 50 años de soberanía estadounidense. Durante este tiempo, el ganado Criollo aportó de modo notable al sustento, economía, cultura y política de nuestro pueblo. Principalmente a partir de la década del 1950, a través de programas de inseminación y de importación de ganado vivo, se introdujo a Puerto Rico (PR) genética mejorada para la producción de leche (i.e., Holstein), teniendo como base a nuestras vacas Criollas. Tras décadas de cruzamientos absorbentes, se ha alcanzado el fenotipo de las razas europeas mejoradas, pero manteniendo ciertas características de adaptación al medio ambiente tropical en una porción del ganado. Entre estas características se destacan un pelaje corto y una capacidad termorreguladora superior, las cuales no se encuentran en el ganado Bos taurus de clima templado. En esta revisión se pretende unir la evidencia histórica sobre el desarrollo de nuestra ganadería con la información científica reciente asociada al progreso de esta empresa y el alto grado de adaptación que nuestros animales han alcanzado ante las condiciones ambientales imperantes.

Gerencia, una Paradoja Epistemológica
Authors: Salcedo (UCV) Irma
Published: May 2020

Desde hace algunos años el sociólogo Juan José Romero Salazar, quien es Master en Gestión Universitaria, Doctor en Ciencias Económicas y Profesor Titular dela UniversidadNacionalExperimental de Guayana, ha venido desarrollando un novedoso abordaje sobre la gerencia, convencido de la necesidad de sustituir el etnocentrismo que impera en ese campo. Su interés ha estado centrado en promover una lectura crítica de la realidad de las organizaciones productivas, para producir conocimientos encaminados hacia la construcción de un nuevo modelo humano-productivo en la industria venezolana.En este libro Romero incorpora un análisis inédito sobre la relación compleja que se establece entre racionalidad, gerencia y sociedad. Comienza por describir cómo la matriz epistemológica de la racionalidad tecno-burocrática, se fundamenta en los aportes vertidos por Taylor en la organización de la cadena productiva con su visión pragmática del trabajo, y luego explaya su argumentación sobre la vinculación del taylorismo con el modelo legal-racional de Max Weber, que sirvió de soporte para el manejo del poder en la estructura empresarial.Considera que estos aportes se orientaron hacia un eficientismo carente de sensibilidad social, que obvia el rol conciente del trabajador y lo limitan a participar en una jornada laboral despersonalizada, dentro de una división técnica del trabajo que fomenta el individualismo y aleja todos los vínculos de la solidaridad y la cooperación en la empresa.Contextualizando lo que él considera una visión estereotipada de la gerencia, Romero incorpora su idea fuerza sobre la paradoja epistemológica, al decir que esta “se convierte en una aporía, que es una especie de “callejón sin salida”, que pudiera llegar a ser una antinomia, porque en si misma constituye una contradicción imposibilitada para aportar conocimientos que estén orientados a la realización integral del trabajador”.*La obra puede ser adquirida en la siguiente dirección:https://www.eae-publishing.com/catalog/details/store/us/book/978-620-2-12201-6/gerencia,-una-paradoja-epistemol%C3%B3gica?search=gerencia
3. Motricidad humana: algo más que un giro lingüístico ¿Qué, del cuerpo y la educación física?
Authors: Reyes Rodríguez (Universidad Adventista de Chile) Alixon David
Published: May 2020

El propósito de este trabajo radica en analizar el estatus del debate que sostiene la representatividad epistémica en el planteamiento que hiciera Manuel Sérgio en referencia a las ‘Ciencias de la Motricidad Humana’, como propuesta científica enmarcándole en el contexto de un denunciado agotamiento de la Educación Física. Para ello se plantea un trabajo de carácter histórico-interpretativo sustentado en la teoría fundamentada, el método dialéctico de Marx y Engels, y la asunción de campo que planteara Bourdieu. Se privilegia la investigación documental con anclajes históricos en el campo de la Educación Física y las Ciencias de la Motricidad Humana, intentando ofrecer algunas aproximaciones en torno a preguntas de investigación: ¿es acaso la motricidad humana, una moda, una tendencia, una corriente?, ¿es una forma de entendernos y situarnos en el mundo?, ¿es una ciencia, tal y como lo plantean Manuel Sérgio y otros investigadores?, ¿cuán sólida se presenta esta propuesta hoy día? Pero, aún más, ¿qué de la Educación Física en este contexto dialéctico?

Authors: Olivero Castro Waldimiro
Published: May 2020

La educación matemática es el área que mayor presenta dificultad es su aprendizaje en los diferentes niveles de la básica. El objetivo de este trabajo es valorar el nivel de evidencia científica que existe sobre el aprendizaje significativo en las matemáticas y su estructura desde el paradigma de la complejidad. La metodología utilizada fue la exploración documental en estrategias de aprendizaje, aprendizaje significativo de las matemáticas y paradigma de la complejidad. Hallándose suficiente documentación que sustentan las recomendaciones realizadas por las sociedades científicas del uso de las estrategias educativas basadas en el aprendizaje significativo de las matemáticas. Se enjuicia entonces que lo propuesto no refleja la realidad a la luz de los resultados en las pruebas del estado, surge entonces un interrogante ¿cuáles son los factores que inciden en la aplicación de estrategias de enseñanza por los docentes de básica primaria para el aprendizaje significativo de las matemáticas?

Published: May 2020

El propósito de éste artículo presentar una visión general sobre la evolución de la legislación ambiental en Venezuela, plantear los problemas ambientales actuales y tomar posición sobre el logro o no del fin último de las legislaciones ambientales, que en el deber ser, serían las de proporcionar y hacer cumplir un conjunto de leyes que gobiernen al estado en materia de ambiente. La modalidad del artículo es Revisión Documental producto de una investigación documental cualitativa. En el artículo se presentan una serie de discusiones en las que se ponen de manifiesto la necesidad humana de crear sustentabilidad a través de sus acciones, contrarrestando la no aplicabilidad de leyes y la inercia de la mayoría de sus habitantes. Los resultados del análisis evidencian que, debemos apuntar hacia una educación ambiental más allá de las leyes promulgadas. Esta educación debe estar basada en valores ecológicos que permitan inducir a la sociedad a pensar ecológicamente para así entonces promover realmente, una vida sostenible.

Authors: García Romero, (Universidad de Los Andes) Marisol Antonia , Andrade Ender
Published: May 2020

En este artículo se analiza los criterios tomados en cuenta para evaluar los 120 trabajos especiales de grado (TEG) producidos en la Especialización en Promoción de la Lectura y la Escritura, de la Universidad de Los Andes, Táchira (Venezuela). para precisar cuán reiterativos o disímiles son los aspectos tomados en cuenta por los árbitros que evaluaron esos TEG, y justificar la propuesta de un instrumento de evaluación que guíe la labor de los árbitros asignados. Se encontró que existe diversidad en los indicadores de evaluación y en las menciones otorgadas por los árbitros. Se proponen dos plantillas de revisión que podrían servir para orientar la valoración de todos los TEG de ese posgrado. Algunos de esos criterios se enfocan en la calidad de la investigación, mientras que otros van dirigidos hacia el rendimiento académico del tesista.
