Effective dynamic modulation of visible light properties has been significantly desired for advanced imaging and sensing technologies. In particular, phase-change materials have attracted much attention as active material platforms owing to their broadband tunability of optical dielectric functions induced by the temperature-dependent phase-changes. However, their uses for visible light modulators are still limited to meet multi-objective high performance owing to the low material quality factor and active tunability in the visible regime. Here, a design strategy of phase-change metafilm absorber is demonstrated by making the use of the material drawbacks and extending design degree of freedom. By engineering tunability of effective anisotropic permittivity tensor of VO2-Ag metafilm around near-unity absorption conditions, strong dynamic modulation of reflection wave is achieved with near-unity modulation depth at desired wavelength regions without sacrificing bandwidth and efficiency. By leveraging effective medium theory of metamaterial and coupled mode theory, the intuitive design rules and theoretical backgrounds are suggested. It is also noteworthy that the dynamic optical applications of intensity modulation, coloring, and polarization rotation are enabled in a single device. By virtue of ultrathin flat configuration of a metafilm absorber, design extensibility of reflection spectrum is also verified. It is envisioned that our simple and powerful strategy would play a robust role in development of miniaturized light modulating pixels and a variety of photonic and optoelectronic applications.

Mitochondrial diseases are a clinically heterogeneous group of multisystem disorders caused by mitochondrial dysfunction. Hepatic involvement is a common feature in neonatal mitochondrial hepatopathies, which may manifest as acute liver failure, hepatic steatohepatitis, cholestasis, or even as chronic liver failure of insidious onset. Mitochondrial diseases are usually severe and rapidly progressive conditions and eventually fatal. However, some of the rare forms show remarkable spontaneous recoveries. The diagnostic process is complex, requiring clinical, biochemical, histological, and genetic investigations. Mutations in several mitochondrial DNA (mt-DNA) and nuclear genes involved in mt-DNA stability and mitochondrial protein synthesis machinery have been associated with mitochondrial disorders. Recently, mutations of TRMU gene encoding mitochondrial tRNA-specific 2-thiouridylase defines the pathomechanism of mitochondrial protein translation defect in the neonatal period presenting with early-onset, reversible liver disease. Here, we report the clinical, biochemical, and genetic findings from one Arab Yamani child presenting with hepatopathy, hyperlactatemia and respiratory chain defect associated with hemophagocytic lymphohistiocytosis, a feature which has not been described in previously reported cases. The aim was to have a prompt definitive genetic diagnosis to provide timely clinical management, decrease morbidity, and improve the survival of the patient. Utilizing next-generation sequencing techniques we identified the pathogenic biallelic mutation c.835G>A (p.Val279Met) in TRMU gene by whole exome sequencing. Since spontaneous recovery is a rare feature in mitochondrial liver disorders, early identification of underlying TRMU mutation can influence clinical management decisions. Our results add to the repertoire of a small number of cases with TRMU mutations reported in mitochondrial liver diseases, for further elaboration of genotype-phenotype correlation.
The evolutionary and disruptive potential of Industrie 4.0
Authors: Winter Johannes
Published: June 2020

Despite all the hype, digitalization is not a new trend. The third industrial revolution started as early as the beginning of the 1970s and has continued to this day. It is shaped using electronics and information technologies (IT) in the economy and progressive standardization and automation of business processes. While exponential growth is typical for the IT sector, this is rarely the case for the classic industries. For a long time, the change was barely perceivable, which led many players to denounce these developments as uninteresting, losing interest at an early stage. But then, as the process picks up breakneck speeds, it often becomes impossible to jump on board or keep up. When automation driven by electronics and IT established itself in production, it led to dramatic changes in value chains and employment structures. Through standardization and automation, business processes became more efficient, quicker, and transparent. When the dot-com speculative bubble burst in 2000, vending machines that ordered supplies independently were already in operation. In the search for the business model of the Information Age, electronic marketplaces became popular pioneers for dynamic business networks and real-time business. Many of today’s well-known technology firms – such as Google, Netflix, or the predecessors of Facebook – were already active on the market in a similar form. In recent years a second wave of digital transformation is experienced and with it, a fourth industrial revolution. The necessary information and communication technologies have now become so cost-effective that they can be used in widespread areas. As a result, many of the dot-com promises have been realized today. The aim of this paper is to intensify the Industrie 4.0 debate in economic geography by showing the evolutionary and disruptive potential of Industrie 4.0.
L' urbanisme transitoire à Montréal : entre innovation et préservation
Authors: Baillargeon Taïka , Diaz Jérémy
Published: June 2020

Longtemps associées à l’activisme et à la transgression, les initiatives d’occupation temporaire des sites vacants sont désormais utilisées par les municipalités dans leur stratégie de réaménagement ainsi qu’envisagées comme vecteur de l’économie créative et comme moteur d’innovation (Bishop et Williams, 2012; Colomb, 2012; Ginez, 2018; Mould, 2014; Pinard et Vivant, 2017). Plusieurs chercheurs envisagent d’ailleurs qu’elles deviennent monnaie courante, s’intégrant à la planification traditionnelle (Bishop et Williams, 2012; Zielh, Oßwald, Hasemann et Schnier, 2012). Dans ce contexte, on parle de plus en plus d’urbanisme transitoire : une pratique qui est autorisée, planifiée et perçue comme une étape de préfiguration pour des projets de requalification pérennes. Qu’est-ce que l’urbanisme transitoire? Comment se distingue-t-il des autres formes d’urbanisme temporaire et comment se déploie-t-il dans le contexte montréalais? Autant de questions auxquelles nous tenterons de répondre dans cet article.
Certain results for a class of nonlinear functional spaces
Authors: Soltanov K. , Sert U.
Published: June 2020

In this article, we study properties of a class of functional spaces, so-called pn-spaces, which arise from investigation of nonlinear differential equations. We establish some integral inequalities to analyse the structures of the pn-spaces with the constant and variable exponent. We prove embedding theorems, which indicate the relation of these spaces with the well known classical Lebesgue and Sobolev spaces with the constant and variable exponents.
Las zonas económicas especiales en México: de política pública a proyecto derogado
Authors: Torres Fragoso Jaime
Published: June 2020

Este artículo aborda la iniciativa de desarrollar zonas económicas especiales en el sur de México, proyecto que, a pesar de que prometía una serie de beneficios en materia de inversiones y generación de empleos para esta región, la más pobre del país, fue cancelado por el gobierno federal que entró en funciones en diciembre de 2018. A través de una exhaustiva revisión del material bibliográfico disponible, y partiendo de la hipótesis de que los posibles impactos positivos de esta política pública superan los negativos, el objetivo de este trabajo es precisamente analizar cuál sería la relevancia de restablecer este proyecto. Para tal propósito, y después de reflexionar en el apartado introductorio sobre las asimetrías del desarrollo en México, la primera sección aborda las características que definen a las zonas económicas especiales promovidas en el plano internacional. Los apartados segundo y tercero abordan, respectivamente, los propósitos y las estrategias en la promoción de estas zonas en el país, y el inicio de estas unidades económicas, considerando las etapas establecidas y las zonas en específico que se pretendían activar. A continuación, se exponen las razones que se plantearon para cancelar este proyecto, y finalmente se presentan las conclusiones y recomendaciones.

Authors: Hernández-Justo Tatiana
Published: June 2020

La preocupación por la causa nacionalista es el eje central en torno al cual pivota el pensamiento del autor tunecino Tahar Haddad (1899-1935). Presente en todas sus obras, el tema cobra especial relevancia en el ámbito del movimiento obrero, que dio lugar a la publicación, en 1927, de una de las obras más conocidas de ?add?d, titulada Al-‘ummal al-tunisiyyun wa-zuhur al-haraka al-niqabiyya (Los trabajadores tunecinos y el surgimiento del movimiento sindicalista). En este artículo, analizaremos los elementos que vinculan nacionalismo y movimiento obrero basándonos en la citada obra.
Educação política e pensamento freireano: sistematizando o diálogo entre luta social e saúde
Authors: Carnut Leonardo , Goraieb Thais Teodoro , Dias da Silva Guerra Lúcia
Published: June 2020

As lutas sociais na saúde são cotidianas e datam, na história recente, desde a criação do Sistema Único de Saúde (SUS) no Brasil. Neste sentido, a formação de novos coletivos que adentram a cena sócio-política e se utilizam da prática pedagógica como um instrumento de luta social vem crescendo. Essa forma de ação/militância política é o que podemos chamar, em grande medida, como ‘educação política’. Assim, este relato de experiênciatem como objetivo refletir sobre a experiência de amadurecimento pedagógico do coletivo ‘Formação Política em Saúde’, identificando os elementos fundamentais do pensamento freireano para qualificar a ação de educação política crítica para a luta social na área da saúde. Para isso realizou-se uma sistematização de experiência sobre os estudos pedagógicos do grupo de leitura ‘Pedagogias Críticas e Saúde,’ cujo foco foi o pensamento freiriano. O grupo de leitura era composto por 12 trabalhadores/estudantes da saúde, que organizavam suas seções através do método da roda. A experiência dos estudos pedagógicos críticos sobre o pensamento freiriano contribuiu para expandir a crítica sobre o processo de formação política e sua práxis, e repensar os modos de emancipação do processo educativo ‘do-discente’ dos membros deste coletivo.

Published: June 2020

Esta publicación es parte del proyecto: “Estudio del magmatismo Mesozoico y sus implicancias en la determinación de un modelo de exploración geológico estructural relacionado con la ocurrencia de Yacimientos tipo IOCG en la Cordillera de la costa y llanuras pre-andinas de los Andes Peruanos” por medio del convenio marco entre UNMSM e INGEMMET. La localización de las áreas prospectables fue usando imágenes Landsat 8, eligiendo Cerro Colorado Chico por su accesibilidad. La geomorfología destaca por mostrar afloramientos de cerros aislados con fuerte oxidación y lomadas. En la etapa de campo se realizó la cartografía geológica de 5 zonas predefinidas y muestreo orientado. Se observó rocas intrusivas, volcánicas porfiríticas alteradas, brechas, vetas de cuarzos, arcillitas. La mineralización observada fue de calcopirita, covelita, gran cantidad de pirita, hematita, goethita, jarosita, etc. La alteración observada fue de fuerte silicificación, oxidación, sericitación, cloritización y piritización. Los resultados de los estudios petromineralógicos han determinado la presencia de rutilo, micas, argilización e incipiente carbonatación. La presencia de brechas silíceas sin mucha mineralización evidente, encontradas en la Zona C-2, podría indicar la presencia de un posible Quartz Pod, además de tener un gran halo hematita-goethita nos podría indicar alteración supérgena y zona de menor temperatura (por la presencia del halo de alteración cuarzo-hematita-sericita-clorita), dando la posible presencia de magnetita en profundidad. En base a estas evidencias se propone la existencia un yacimiento tipo IOCG en la Zona C-2, probablemente profundo que con mayores estudios enfocados se corroboraría esta hipótesis.

Minimal phrase structure: a new formalized theory of phrase structure
Authors: Lowe John , Lovestrand Joseph
Published: June 2020

X' theory was a major milestone in the history of the development of generative grammar.1 It enabled important insights to be made into the phrase structure of human language, but it had a number of weaknesses, and has been essentially replaced in Chomskyan generativism by Bare Phrase Structure (BPS), which assumes fewer theoretical primitives than X0 theory, and also avoids several of the latter’s weaknesses. However, Bare Phrase Structure has not been widely adopted outside the Minimalist Program (MP), rather, X0 theory remains widespread. In this paper, we develop a new, fully formalized approach to phrase structure which incorporates insights and advances from BPS, but does not require the Minimalist-specific assumptions that come with BPS. We formulate our proposal within Lexical-Functional Grammar (LFG), providing an empirically and theoretically superior model for phrase structure compared with standard versions of X0 theory current in LFG.

Published: June 2020

Asian elephants are under high threats of extinction in Vietnam and worldwide. Population assessment of Asian elephants in Pumat National Park (NP) region, carried out in 2018−2019, showed that the wild Asian elephants population this region consisted of 3 groups with a total of 13−14 individuals. In Tuong Duong District, a group of 4-5 individuals lived in an area near Canh Ta stream (Tam Dinh commune, Vietnam) and Nam Xi stream (Muong Long commune, Laos), across the border between Vietnam and Laos. The group in Con Cuong district, with only one adult female, lived in forest compartments 780, 781,789 and 786 of Con Cuong Forestry Company, within the buffer zone of Pumat NP. The group in Anh Son district consisted of 8 individuals (5 adult females, 1 adult male, 1 sub-adult male and an juvenile born in 2016). They live in Cao Veu sector of Pumat NP core zone and buffer zone areas consisting of protected forests, rubber plantation forests and agricultural lands of households in Phuc Son Commune (Anh Son District) and Thanh Duc Commune (Thanh Chuong District).Wild Asian elephants in Pumat NP region are facing dangers of extinction due to their small number as well as direct and indirect threats from human. The elephant group in Anh Son district, with the largest number of individuals consisting of breeding males, breeding females and a calf, is the most important for the maintainance and future development of elephant population within Puman NP. However, they are facing a number of  serious threats such as: un-controlled wildlife hunting and trade; rapid decrease and degradation of natural forest outside of Pumat National Park; and increasingly serious human-elephant conflicts.
Virtual reality videos for training and protocol dissemination during a pandemic

Published: June 2020

This article was migrated. The article was marked as recommended. Preparations for the COVID-19 pandemic required healthcare teams to practice known skills, such as intubation, with renewed consideration for safety, as well as develop new Standard Operating Procedures (SOPs) for health care delivery. In these conditions, translational simulation based-education (SBE) is a well-known tool that supports health care teams to improve the system using design thinking methods such as walkthroughs and team-based simulation. However, the pandemic has introduced two stressors on translational SBE simultaneously. Firstly, the need for rapid upskilling of front-line staff and rapid change to SOPs. Secondly, the need for social or physical distancing at work, such that it quickly became inappropriate for large groups of individuals to practice in-situ SBE and debrief together in close proximity. An educational approach that brings the best of translational SBE while minimizing contact and maximizing experiential learning is needed.Digital learning has been rapidly adopted by much of medical education during the pandemic. Focusing on a strong alignment between learning goals with intended clinical performance change outcomes we sought to leverage a digital education format that allowed for low barriers to adoption, yet supported the experiential, dynamic reality of translational SBE. In the absence of the ability to quickly train large numbers of people due to the need for social distancing, an immersive experience that can only be provided by virtual reality (VR) videos was the next best thing. VR, using 360-degree video, supported the creation of instructional videos from SBE events in the hospital which allow the learner to immerse and explore multiple points within the scenario. We describe how the very act of recording a video assisted in the rapid development of SOPs through translational simulation. We then describe the use of VR to stay true to the spirit of simulation for experiential learning and nearly hands-on training.
Selection of waterlogging-tolerant and water purification herbaceous plants for the construction of a sponge city in Shenzhen, China
Authors: SUN Bing , PAN Xiao , HAN Liebao , FEI Yongjun
Published: June 2020

In recent years, seeking solutions to urban waterlogging and water pollution has always been one of the topics of concern. The problem of urban water accumulation occurs frequently in most areas of China in July and August. The contradiction between supply and demand of urban ecological water is prominent. In order to solve the problem of urban water accumulation caused by rainfall concentration, and to achieve the overall goal of building a water-saving green ecological city, the Shenzhen City should be built into a sponge city. Under this background, the physiological response of different forages to waterlogging stress and the removal of pollutants in rainwater were studied. In this study, ten herbaceous plants commonly used in Shenzhen were used as experimental materials. After 0, 7, 14, 21, 28 days of waterlogging stress treatment, six physiological indexes, such as MDA, SP, and Pro contents and SOD, POD, and CAT activities, were comprehensively evaluated. Combined with the morphological changes of the plants after waterlogging, seven plants with strong waterlogging tolerance were determined, which were O. bodinieri, H. coronarium, I. tectorum, D. ensifolia, R. brittoniana, C. indica, and A. zerumbet. Then, according to their comprehensive evaluation of the removal capacity of pollutants in the rainwater, it is suggested to select O. bodinieri, H. coronarium, I. tectorum and D. ensifolia in areas with serious waterlogging. In areas with serious water pollution, R. brittoniana, A. zerumbet, D. ensifolia and H. coronarium are recommended. However, H. coronarium and D. ensifolia not only have a strong adaptability in the waterlogged environment, but also have a strong ability to remove pollutants in the rainwater, so they are suggested to be alternative herbaceous plants for sponge city in Shenzhen, China.

In the process of bacteria inoculation K, Ca and Mg content of inoculation; N, P, Mn, Zn and Cu content of ½ NPK fertilization was determined to be effective.
Effects of combined pretreatments on germination and emergence of wild Eremurus spectabilis M.Bieb. seeds
Authors: AKDAĞ Şeref , TUNCER Burcu
Published: June 2020

Eremurus spectabilis is a perennial herbaceous species that grows in the wild. Commonly consumed as a vegetable, it is also classified among medicinal plants and popular ornamental geophytes. Germination is not achieved under normal conditions because of seed dormancy. In this study, various combined treatments were experimented with to improve the germination and emergence performance of E. spectabilis seeds. The seeds were immersed in solutions of potassium nitrate (KNO3: 5 mM for 24 and 48 hours), calcium chloride (CaCl2: 5 mM for 24 and 48 hours) and subjected to tip cutting. Pre-treated seeds were then subjected to moist-cold stratification periods treatments for different durations (30, 50, 80 and 100 days). In the 5 mM KNO3 treatments, 48-hour KNO3 and 100 days of stratification treatments had better germination (11.1%) and emergence values (9.7%). In the 5 mM CaCl2 treatments, 24-hour CaCl2 yielded better germination (10.2%) and emergence (8.4%) values. Seed tip-cutting treatments were the most successful among all the treatments for the germination and emergence parameters.

In a greenhouse experiment, the inoculated and uninoculated grains with Azospirillum brasilense NO40 or Stenotrophomonas maltophilia were sown in unsterilized sandy soil and watered normally till the 8th day. Thereafter, the drought stress was initiated by watering pots once every 10 days while the unstressed pots were irrigated normally once every 5 days. Samples of spikes and dry grains were collected after 120 days from sowing. The results indicated that the inoculated-drought-stressed plants maintained significantly higher values of all of the measured yield parameters, where the yielded grains had higher amounts of the direct reducing sugars, sucrose, starch; lower contents of total soluble proteins and the total free amino acids, and altered protein patterns compared to those of the uninoculated-drought-stressed plants. SDS-PAGE of the yielded grains showed that drought led to the appearance of some newly synthesized stress protein bands and disappearance of others. Inoculation with PGPB resulted in the re-appearance of some of the disappearing bands and the synthesis of new others. Meanwhile, wheat inoculation under normal conditions resulted in significantly promoted grain yields with higher contents of carbohydrates, total soluble proteins and total free amino acids than that of the uninoculated control. It has been proved that treating wheat plants with the PEG-tolerant Azospirillum brasilense NO40 or Stenotrophomonas maltophilia that were compatible with the systems into which they were introduced and possess multiple plant growth promoting traits, can be an efficient strategy to enhance wheat growth and productivity, not only under normal conditions, but also under drought stress.

The morpho-anatomical characteristics of Lindernia diffusa var. diffusa-in E. & P., L. oliveriana (Benth.) Wettst. and L. crustacea (L.) F. Muell.) were investigated with a view of providing additional line of evidence in the delimitation of the species in Nigeria. The specimens were subjected to microtomy. The anatomy, fruit morphology, leaf shape, number of fruits per node and, flower colour differed among the species. The species have two trichome types (glandular and non-glandular) with varying number of gland head and basal cells. The glandular trichomes have 4-7 gland heads and 4-8 basal cells while the non-glandular type-1 and 2 trichomes with 5-10 basal cells. Type-1 non-glandular trichome occurred in L. crustacean and L. diffusa var. diffusa while type-2 occurred in L. oliveriana. The palisade and spongy mesophylls are 1-layer and 3-5 layers respectively in L. diffusa var. diffusa, 1-2 layers and 4-6 layers in L. oliveriana and 2-3 layers and3 layers in L. crustacea. The palisade and spongy mesophylls are poorly differentiated. Two to five vascular bundles at the basal and distal ends of the petioles were observed in the Lindernia species with the main vascular bundle forming circular-united or fussed vascular bundles in L. diffusa var. diffusa and L. crustacea and arced or horizontally elongated vascular bundle separated by parenchymatous rays in L. oliveriana. In L. diffusa var. diffusa, the pith covered 55.99% of the stem, 24.27% in L. crustacea and 72.74% in L. oliveriana. These characters could be used to delimit the species studied.

The family Leiognathidae, commonly known as ponyfish and they are mainly classified by mouth morphology. In this study, genetic variation and phylogenetic relationships among nine genera and 13 species of Leiognathidae, inferred from Cytochrome Oxydase I gene. The Neighbour Joining tree showed the paraphyly of the studied species form genus Secutor and monophyly status all the other eight genera. Leiognathus equulus is occupying a basal branch of the family NJ tree. The highest genetic distance (0.349) showed between Eubleekeria and Nuchequula. The lowest genetic distance (0.007) showed between the genus Nuchequula and Leiognathus. Among the nine genera, very less nucleotide diversity (π= 0.1100) was in Secutor and higher value (π = 0.7558) was recorded in Leiognathus. The Tajima’s test statistic (D) value was positive, so, the entire genus is in balancing selection.

Sustainable Warehousing: Selecting The Best Warehouse for Solar Transformation
Authors: BOZTEPE Rasih , ÇETİN Onur
Published: June 2020

Environmental sustainability has been gaining importance not only in manufacturing but also in logistics and suply chain. Logistics sector has a significant responsibility in global energy consumption. The effect of warehouse on carbon emission demonstrates its importance about sustainability. One way of developing sustainable warehouses is using renewable energy sources. In a solar warehouse; which is an important example of sustainable warehousing, roof of the warehouse is covered with solar panels so, both energy costs and carbon emission are reduced. Warehouses have been turning into solar warehouse in recent years. In this situation economic dimension and environmental dimension of sustainability should be considered. While there is a substantial literature regarding sustainable supply chain, literature regarding sustainable warehousing is limited. In order to contribute this gap in the literature the problem conducted here is the determination of solar warehouse location. The aim of the research is to determine best location for a solar warehouse among alternatives. In this context first the alternative warehouses that can be turned into solar warehouse are determined then, the criteria which will be used in selection process is obtained from previous research. TOPSIS method is used to select the best location between six alternative locations. The evaluation of alternatives according to the criteria is obtained from expert opinions and secondary data. Alternatives are sorted according to TOPSIS results. The alternatives ranking list is compared with the ranking list obtained according to return on investment and some differences were observed between environmental and economic ranking lists.

UV absorbers are used to reduce the harmful effects of UV rays and to ensure that the properties of the materials are adequately protected. To protect against UV rays, one of the UV absorber molecules can reduce the combined energy of radiation to thermal energy that provides less energy in a photophysical process. Inorganic materials such as metal oxide semiconductors can effectively absorb UV irradiation and exhibit good heat-resistance properties. TiO2, CeO2, and ZnO are inorganic compounds with UV protective properties. Since some of these compounds are colored, their use is limited. Boron nitride nanosheets (BNNSs) are alternative UV inhibitors to these inorganic compounds. In this study BNNSs/PVB multilayer thin films were produced for the protection of glass packages using the dip-coating method. Riviera olive oil (RO-oil) samples in the both coated and uncoated bottle were exposed to UV irradiation for different times (75, 170, 360 and 720 hours). After the UV irradiation at different times, the total phenol and antioxidant contents in RO-oil were determined by Folin Ciacalteu and DPPH methods. The color change of RO-oil after UV irradiation was determined by UV visible spectrophotometer. Specific absorption coefficients K232 and K270 in the ultraviolet region were measured to determine the oxidation degree of RO-oil after degradation. Free fatty acid (FFA) of RO-oil after UV irradiation was determined by the titration method. According to the results of the analysis, the acidity values of RO-oil were preserved 20 times compared to the uncoated glass bottle after 720 hours UV. BNNSs/PVB coating was also effective in preserving total phenol, antioxidant contents and oxidation state of RO-oils under long term UV irradiation.
Revisión de propuestas metodológicas: una taxonomía de agrupación categórica
Authors: Rodríguez-García Alejandro , Arias-Gago Ana Rosa
Published: June 2020

Actualmente, no existe ninguna taxonomía vinculada a la metodología que agrupe diferentes elementos metodológicos en función del carácter activo e instructivo de los mismos y de la etapa educativa a la que mejor se adecúen en términos de utilización. Por ello, el objetivo de esta investigación fue establecer una taxonomía considerando 76 recursos, estrategias, técnicas y métodos didácticos obtenidos tras una revisión de la principal literatura nacional e internacional. Para establecer la taxonomía, se elaboró y validó por medio del procedimiento de juicio de expertos la escala EVEMDT. La misma, fue administrada a un panel de 30 expertos quienes asistieron a un seminario de formación impartido por los investigadores, para valorar el carácter instructivo o activo y la adecuación a la etapa educativa de los 76 elementos metodológicos. Los resultados permitieron establecer una taxonomía donde aparecen 25 y 51 recursos, estrategias, técnicas y métodos didácticos instructivos y activos respectivamente, clasificados también en función de la etapa educativa a la que mejor se adapten en términos de utilización. Se concluye que, las taxonomías con las que comparar los resultados son exiguas, aspecto que permite a esta ser un referente para los docentes a la hora de decidir qué recursos, estrategias, técnicas y métodos didácticos utilizar en función de la etapa educativa en la que se ubique el alumnado y el papel que quieran dotarle en sus procesos de aprendizaje.
