Background

Circulating tumour cells (CTCs) represent a morphologically distinct subset of cancer cells, which aid the metastatic spread. The ExPeCT trial aimed to examine the effectiveness of a structured exercise programme in modulating levels of CTCs and platelet cloaking in patients with metastatic prostate cancer.

Methods

Participants (n = 61) were randomised into either standard care (control) or exercise arms. Whole blood was collected for all participants at baseline (T0), three months (T3) and six months (T6), and analysed for the presence of CTCs, CTC clusters and platelet cloaking. CTC data was correlated with clinico-pathological information.

Results

Changes in CTC number were observed within group over time, however no significant difference in CTC number was observed between groups over time. Platelet cloaking was identified in 29.5% of participants. A positive correlation between CTC number and white cell count (WCC) was observed (p = 0.0001), in addition to a positive relationship between CTC clusters and PSA levels (p = 0.0393).

Conclusion

The presence of platelet cloaking has been observed in this patient population for the first time, in addition to a significant correlation between CTC number and WCC.

A theoretical model of neural maturation in the developing chick spinal cord
Authors: Joshi Piyush , Skromne Isaac
Published: December 2020

Cellular differentiation is a tightly regulated process under the control of intricate signaling and transcription factors interaction network working in coordination. These interactions make the systems dynamic, robust and stable but also difficult to dissect. In the spinal cord, recent work has shown that a network of FGF, WNT and Retinoic Acid (RA) signaling factors regulate neural maturation by directing the activity of a transcription factor network that contains CDX at its core. Here we have used partial and ordinary (Hill) differential equation based models to understand the spatiotemporal dynamics of the FGF/WNT/RA and the CDX/transcription factor networks, alone and in combination. We show that in both networks, the strength of interaction among network partners impacts the dynamics, behavior and output of the system. In the signaling network, interaction strength determine the position and size of discrete regions of cell differentiation and small changes in the strength of the interactions among networking partners can result in a signal overriding, balancing or oscillating with another signal. We also show that the spatiotemporal information generated by the signaling network can be conveyed to the CDX/transcription network to produces a transition zone that separates regions of high cell potency from regions of cell differentiation, in agreement with mostin vivoobservations. Importantly, one emerging property of the networks is their robustness to extrinsic disturbances, which allows the system to retain or canalize NP cells in developmental trajectories. This analysis provides a model for the interaction conditions underlying spinal cord cell maturation during embryonic axial elongation.

Published: December 2020

Childhood obesity is one of the most serious public health problems. The prevalence of obesity among children is increasing and may negatively affect their immediate health, but it can also lead to obesity in adulthood. The aim of the study was to compare BMI cut-off points by examining three main international references: the World Health Organization (WHO), the International Task Force Obesity (IOTF) and the US Center for Disease Control and Prevention (CDC). Ultimately, the study group consisted of 18,144 children and adolescents aged 6.5–17.5 years. Body mass was measured on medical scales with an accuracy of ± 100 g and height measurement was taken using a height meter with an accuracy of ± 0.1 cm three times. Underweight, overweight and obesity were calculated according to WHO, IOTF and CDC BMI international references. There were differences in the incidence of underweight between the classifications: 16.8% according to IATF, 5.3% according to WHO and 9.9% according to CDC. There were also differences in the incidence of overweight and obesity between the classifications: 13% according to IOTF, 19.7% according to WHO and 14.1% according to CDC. In the CDC and WHO studies, a significantly higher prevalence of childhood obesity (4.0% and 4.7%, respectively) was observed compared with IOTF (2.1%). The prevalence of overweight and obesity in this study was higher among boys compared to girls. However, estimates of prevalence of overweight and obesity differ in methods and reference cut-off points. Higher prevalence was obtained in IOTF classification, followed by the WHO and CDC classification.

Background

Few studies demonstrate delayed recovery after exercise in children and adults with heart disease. We assess the recovery patterns of gas exchange parameters and heart rate (HR) in children with repaired Tetralogy of Fallot (rToF) compared to healthy peers and investigate the correlation with ventricular function and QRS duration.

Methods

45 children after rToF and 45 controls performed a maximal incremental cardiopulmonary exercise test. In the subsequent recovery period, patterns of VO2, VCO2 and HR were analysed. Half-life time (T1/2) of the exponential decay and drop per minute (Recmin) were compared between groups. In the rToF group, correlations were examined between the recovery parameters and QRS-duration and ventricular function, described by fractional shortening (FS) and tricuspid annular plane systolic excursion (TAPSE) measured at baseline prior to exercise.

Results

Recovery of VO2 and VCO2 was delayed in rToF patients, half-life time values were higher compared to controls (T1/2VO2 52.51 ±11.29 s vs. 44.31 ± 10.47 s; p = 0.001 and T1/2VCO2 68.28 ± 13.84 s vs. 59.41 ± 12.06 s; p = 0.002) and percentage drop from maximal value was slower at each minute of recovery (p<0.05). Correlations were found with FS (T1/2VO2: r = -0.517; p<0.001; Rec1minVO2: r = -0.636, p<0.001; Rec1minVCO2: r = -0.373, p = 0.012) and TAPSE (T1/2VO2: r = -0.505; p<0.001; Rec1minVO2: r = -0.566, p<0.001; T1/2VCO2: r = -0.466; p = 0.001; Rec1minVCO2: r = -0.507, p<0.001), not with QRS-duration. No difference was found in HR recovery between patients and controls.

Conclusions

Children after rToF show a delayed gas exchange recovery after exercise. This delay correlates to ventricular function, demonstrating its importance in recovery after physical activity.

Published: December 2020

Introduction

The scoping review examined the evidence related to infection control and transmission measures of the SARS-CoV-2 virus in a dental setting during this pandemic. Dental practitioners are normally guided in practice by set ethical principles, thus the researchers wanted to determine how these rules are managed during this pandemic.

Methods

A protocol specific for the objectives of this study was developed according to the criteria for a scoping review. Relevant databases (Pubmed, Scopus, Elsevier, Science Direct, Wiley), including online access to health/ dental organizations (World Health Organization/ American Dental Association), were searched to identify evidence which was restricted to the English language for the period 2015–2020. Predetermined eligibility criteria were applied, evidence was assessed and data extracted for each included article. Relevant outcomes assessed were: infection control measures, transmission of the SARS-CoV-2 virus, such as modes and sources of transmission and the ethical principles related to the dental setting with a focus on the COVID-19 pandemic.

Results

Searches yielded a total of 402 articles: 387 from electronic databases and 15 from other sources. Of these, 231 were unrelated to the objectives of the current scoping review. The full text of 69 studies was assessed for eligibility, of which 26 were finalized for inclusion following the objectives and inclusion criteria set for the scoping review. Most of the included articles were reviews, recommendations and guidelines for dentists. A narrative explanation of the pre-specified outcomes is reported for the 3 areas covered for this review. There is no clinical evidence available that can support the recommendations by individuals, dental organizations or health authorities related to the objectives of this review, but these may be considered as the much needed guidelines during the unprecedented COVID-19 pandemic. A different ethical framework is required during a pandemic and these must be informed by evidence.

Published: December 2020

Metronidazole is an antibiotic and useful for the antibacterial and antiprotozoal medication. This study was performed to investigate the impact of the Trivedi Effect®-Biofield Energy Healing Treatment on the structural properties and the isotopic abundance ratio of metronidazole using LC-MS and GC-MS spectroscopy. Metronidazole sample was divided into two parts, one part of metronidazole was considered as control (no Biofield Energy Treatment was provided), while the second part was treated with the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a renowned Biofield Energy Healer, Alice Branton and termed as a treated sample. The LC-MS spectra of both the samples of metronidazole at the retention time (Rt) 2.61 minutes exhibited the mass of the protonated molecular ion peak at m/z 172 M+H+ (calculated for C6H10N3O3+, 172.07). The LC-MS based isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 15N/214N or 17O/16O) in the treated metronidazole was significantly increased by 8.24% compared with the control sample. Thus,13C, 2H, 15N,and17O contributions from (C6H10N3O3)+ to m/z 173 in the treated sample were significantly increased compared with the control sample. The GC-MS based isotopic abundance ratio of PM+1/PM in the treated metronidazole was significantly increased by 5.92% compared with the control sample. Hence,13C, 2H, 15N, and217O contributions from (C6H9N3O3)+ to m/z 172 in the Biofield Energy Treated sample were significantly increased compared with the control sample. However, the isotopic abundance ratio of PM+2/PM in the treated metronidazole was significantly decreased by 18.2% compared with the control sample. Hence,18O contributions from (C6H9N3O3)+ to m/z 173 in the treated sample were significantly decreased compared with the control sample. The isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 15N/14N or 17O/16O) and PM+2/PM (18O/16O) in the treated metronidazole was significantly altered compared to the control sample. From the results, it can be hypothesized that the changes in isotopic abundance and mass peak intensities could be due to changes in nuclei possibly through the interference of neutrino particles via the Trivedi Effect® - Consciousness Energy Healing Treatment. The new form of treated metronidazole would be better designing novel pharmaceutical formulations that might offer better therapeutic response against bacterial and protozoal infection in the vagina (bacterial vaginosis), stomach (giardiasis, trichomoniasis, pseudomembranous colitis), joints (pelvic inflammatory disease), liver, skin, brain, and respiratory tract, aspiration pneumonia, rosacea, intra-abdominal infections, lung abscess, fungating wounds, periodontitis, amoebiasis, oral infections, etc.

Published: December 2020

In the recent years, biochar has been used as an organic soil amendment. Therefore, this study was undertaken in April 2016 to July 2017 to examine the effect of different biochar addition (BA) rates and deficit irrigation (DI) on quality characteristics of cucumber under greenhouse conditions over two consecutive growing seasons. The BA treatments were B0 (0-ton ha-1), B1 (10-ton ha-1and B2 (20-ton ha-1), while the DI treatments were 1.0 (W1), 0.60 (W2) and 0.40 (W3) of the reference evapotranspiration (ET0). The results obtained elaborated that the combination of B2W1 gave the maximum values of fruit weight (g), fruit water content (%), fruit dry biomass (g) and pH in the both seasons. On the other hand, W2 and W3 increased significantly titratable acidity (TA %) and total soluble solid (TSS %). It was possible to conclude that BA with DI might be a novel approach to improve both crop yield and fruit quality.

Published: December 2020

This work aimed to compare the antifungal activity of the essential oil of Varronia curassavica obtained by hydrodistillation and microwave against the fungus Colletotrichum musae and verify the alterations caused by these extraction methods on the leaf surface. This study used four essential oil samples obtained by different methods, two by hydrodistillation [HD1 (1.0 L of water and 100 min.) and HD2 (2.0 L of water and 140 min.)] and two by microwave [MI1 (500W, 20 min, without water) and MI2 (700W, 40 min, with 50 mL of water added to fresh leaves)]. Essential oils concentrations of 0.05, 0.1, 0.5, 1.0, and 3.0% (v / v) were tested in PDA medium. The mycelial growth of C. musae was evaluated by measuring the diameter, every 24 hours up to 144 hours after the beginning of the incubation. Untreated leaves and leaves treated with HD1 and MI1 were prepared for observation in a scanning electron microscope (SEM) LEO EVO 40. The most abundant compounds detected in the essential oil samples analyzed by gas chromatography were: shyobunol, germacrene D-4-ol, E-caryophyllene, bicyclogermacrene, and α-cadinol. Up to 72 hours after the beginning of the incubation, C. musae presented no mycelial growth, even at the lowest essential oil concentration. Conversely, mycelial growth was detected in the control (PDA + DMSO) from 24 hours after incubation. At 144 hours after incubation, regardless of the concentration, the essential oil samples obtained by HD provided lower mycelial growth of C. musae (1.49 cm) when compared with samples obtained by MI (1.80 cm). This difference possibly occurred due to the reduction to less than half of the germacrene D-4-ol content in the samples obtained by MI. The four essential oil samples tested inhibited the mycelial growth and thus presented a inhibitory effect on C. musae. The SEM revealed more drastic changes on the surface of the leaf treated with MI than on those treated with HD. The essential oil of V. curassavica, mainly when obtained by hydrodistillation, has the potential for use in the control of C. musae.

Published: December 2020

The physiological quality of seeds is influenced by the climatic factors of production fields. The identification of the best conditions of P. maximum cv. Mombasa production fields allows the improvement of the seed sector. The aim of this work was to identify which climatic conditions of production fields can affect the physiological quality of P. maximum cv. Mombasa seeds. Nineteen plots from states of São Paulo (six from municipalities of Auriflama and three from Guzolândia) and Goiás (eight from Quirinópolis and two from Serranópolis), were collected by soil sweeping. The following parameters were evaluated: water content, germination rate, first germination count and germination rate index, seedling emergence in sand and field. Completely randomized design was used for all variables, with the exception of seedling emergence in field, since this variable required block design. Means were compared by the Scott-Knott test, at 5% probability. For the identification of the influence of climatic conditions on the physiological quality of seeds, multivariate statistical analysis was applied through Group and Principal Component Analysis. Production fields of Panicum maximum cv. Mombasa seeds presenting maximum temperatures above 32 ºC at flowering and natural fall stages produce seeds of low physiological quality. Production fields in which precipitation and high temperatures occur during natural fall and harvest of P. maximum cv. Mombasa seeds are not favorable to the production of seeds with high physiological quality.

Published: December 2020

The objective of this work was to evaluate the abundance of the soil macrofauna in four green manure species, before the cotton crop. The experimental design was a randomized block design with four treatments: Mucuna pruriens (gray mucuna), Canavalia ensiformes (pork bean), Cajanus cajan (pigeon pea) and Crotalaria juncea (crotalaria). The macrofauna was captured by means of collections with collections using pitfall traps. The data were processed through the cluster analysis to verify the similarity among green manure species as to the occurrence of soil macrofauna. The orders Orthoptera, Coleoptera L (Larval), Hymenoptera and Coleoptera (adult), respectively, had the highest local relative abundance. There was a significant effect of the cover plants on the taxonomic groups and relative density of the soil macrofauna. Green manures were more determinant in the abundance and relative density of the soil macrofauna than the region climate. Up to 60 days after sowing the cotton crop, there was a beneficial influence of the green manures on the soil macrofauna.

Published: December 2020

The dual-purpose wheat stands out as a complementary alternative for forage supply during the winter period. Therefore, this work had the objective of evaluate the performance characteristics in five genotypes of dual-purpose wheat submitted to different sowing densities and different clipping managements. The experiment was carried out during the 2016 and 2017 harvests. The experimental design was a randomized block design, organized in a factorial scheme, with five dual-purpose wheat genotypes (BRS Tarumã, BRS Umbu, BRS Figueira, BRS Guatambu and BRS 277) x five sowing densities (75, 150, 225, 300 and 375 seeds m²) x four clipping operations (zero, one, two and three clippings), arranged in three replicates. The measuring of characters were number of fertile tillers, seeds yield, angle of flag leaf, chlorophyll content and flowering. The genotype BRS Tarumâ is superior in number of fertile tillers and chlorophyll index for all the sowing densities, as well, the flowering is influenced direct by clipping managements.  The sowing density of 75 seeds m-2 is not indicated for dual-purpose wheat independent of the clipping management. The seeds yield is amplified thought the increase in sowing density, however, advancing in clipping levels there is a decrease in forage yield.

Published: December 2020

Following the harvest, agricultural products are subjected various negative impacts throughout the way to consumers. Mechanical damages such as color darkening, abrasion, cuts or punctures over the fruit surface are irreversible damages and such damages ultimately end up with significant quality and economic losses. In modern production systems, only a certain portion of the products directly reach from producer to consumers. Majority of these products are subjected to mechanical damages through crush, squeeze, vibration and similar impacts during the harvest and postharvest processes. In this study, Tybeef tomato cultivar grown over the experimental greenhouses of Bati Akdeniz Agricultural Research Institute (BATEM) (control) and 14-193 and 14-206 coded candidate cultivars developed through breeding programs of BATEM were used as the plant material. Resistance parameters of tomato cultivars were determined at 4 different ripening stages (green, turning, pink and red) and 4 different storage durations (4, 8, 12 and 16 days). Resistance parameters decreased with the progress of ripening and storage durations. All measurements and assessments revealed that 14-193 coded candidate cultivar was prominent for resistance parameters.

Published: December 2020

The study was design to investigate the clinical effect of Micro implant system in Italy on immediate mandibular implant-supported overdenture. A total of 192 patients with mandibular edentulous treated in our hospital were randomly divided into 2 groups in which the control group consisted of 96 patients treated with immediate mandibular implant-supported overdenture by Xive implant system, while the observation group included 96 cases treated with the overdenture by Italy Micro implant system. Patients were followed up for 1 year and then the states of implant-borne overdentures, marginal bone resorption around alveolar bone, the compatibility of implant restorations with adjacent teeth, adverse events and satisfaction degree were compared between the groups. According to the results of 1-year follow-up, the resorption around alveolar bone of the observation group was significantly higher than that of the control group (p<0.05). In the observation group the differences in labial gingival margin position, gingival color and texture were significantly better (p<0.05) as compared to control group. The incidence of adverse events was notably lower (p<0.05). The Italy Micro implant system has significant curative effect on mandibular implant-supported overdentures with good compatibility of the implant restorations with adjacent teeth and low incidence rate of adverse reactions, so it is worthy of clinical application and spreading.

Published: December 2020

Este artigo busca investigar e questionar a flexibilização dos instrumentos de planejamento urbano relativamente à densidade urbana. Para tal, toma como estudo de caso o município de Passo Fundo/RS, onde observou-se que o Plano Diretor de Desenvolvimento Integrado (PDDI), instituído em 2006, passou por uma série de alterações relacionadas ao regime urbanístico proposto. Para alcançar o objetivo buscou-se uma análise dos atos legais, identificando aqueles que refletiram sobre o planejamento das densidades (construtiva e populacional). Posteriormente recorreu-se a elaboração de mapas-síntese dos índices urbanísticos, possibilitando especializar as alterações e analisa-las comparativamente. Por fim, através da Teoria da Sintaxe Espacial, foi possível caracterizar as localizações em áreas mais integradas e segregadas. Como conclusão, observou-se que a flexibilização do PDDI ocorreu majoritariamente em áreas de baixa integração e que sua apropriação à materialidade urbana já ocorre, sobretudo pela tipologia de condomínios do programa Minha Casa, Minha Vida, destinados à baixa renda.
Cognitive load in processing ELF: Translators, interpreters, and other multilinguals

Published: December 2020

Many factors can affect the translation and interpreting process, but the quality of source texts has been explicitly identified as an issue in surveys of professional translators and interpreters as well as in recent workplace studies. If translators and interpreters encounter resistance in carrying out their tasks, for example by difficulties in extracting meaning from non-native English input, then flow can be interrupted and performance affected. In this paper, we explore how English as a lingua franca (ELF) input could potentially increase the cognitive load not only for translators and interpreters but also for other multilinguals. We describe the range of methods that can be used to measure the cognitive effort and stress associated with processing ELF input and explain the challenges that can be encountered when researchers are committed to using authentic ELF material to make comparisons under relatively controlled but ecologically valid conditions. One of the driving motivators for this type of research is to understand how interpreters and translators deploy their expertise to deal with ELF input in work settings in order to draw inferences about strategies for other segments of the population.

La innovación hacia una economía sustentable no ha tenido los efectos deseados. Ante ello, desde las ciencias sociales, la Perspectiva Multinivel (MLP, por sus siglas en inglés) estudia los retos que innovaciones disruptivas enfrentan para transformar mercados consolidados. No obstante, en su enfoque global, el modelo ha sido criticado por la articulación insuficiente de conceptos en la dimensión micro. En respuesta a este llamado, el objetivo del artículo consiste en identificar los primeros nichos tecnológicos de bioplásticos para estudiar las alianzas entre agentes con la intención de penetrar el mercado, así como los elementos del contexto que las facilitaron. Mediante una investigación bibliográfica y de patentes, se identificó a los primeros inventores, empresas, marcas, aplicaciones y circunstancias del contexto que dificultaron o facilitaron el desarrollo de los nichos. Nuevas aplicaciones son señaladas. Los hallazgos proporcionaron una retroalimentación a posteriori entre nichos de funciones societales diferentes, lo cual condujo a proponer el concepto de latencia tecnológica entre nichos.

Published: December 2020

Benthic organisms depend primarily on seasonal pulses of organic matter from primary producers. In the Arctic, declines in sea ice due to warming climate could lead to changes in this food supply with as yet unknown effects on benthic trophic dynamics. Benthic consumer diets and food web structure were studied in a seasonally ice-covered region of Baffin Bay during spring 2016 at stations ranging in depth from 199 to 2,111 m. We used a novel combination of highly branched isoprenoid (HBI) lipid biomarkers and stable isotope ratios (δ13C, δ15N) to better understand the relationship between the availability of carbon sources in spring on the seafloor and their assimilation and transfer within the benthic food web. Organic carbon from sea ice (sympagic carbon [SC]) was an important food source for benthic consumers. The lipid biomarker analyses revealed a high relative contribution of SC in sediments (mean SC% ± standard deviation [SD] = 86% ± 16.0, n = 17) and in benthic consumer tissues (mean SC% ± SD = 78% ± 19.7, n = 159). We also detected an effect of sea-ice concentration on the relative contribution of SC in sediment and in benthic consumers. Cluster analysis separated the study region into three different zones according to the relative proportions of SC assimilated by benthic macrofauna. We observed variation of the benthic food web between zones, with increases in the width of the ecological niche in zones with less sea-ice concentration, indicating greater diversity of carbon sources assimilated by consumers. In zones with greater sea-ice concentration, the higher availability of SC increased the ecological role that primary consumers play in driving a stronger transfer of nutrients to higher trophic levels. Based on our results, SC is an important energy source for Arctic deep-sea benthos in Baffin Bay, such that changes in spring sea-ice phenology could alter benthic food-web structure.

"Canción de hielo y fuego". La huella del mito
Authors: Cáceres Blanco Roberto
Published: December 2020

La influencia de la épica y de la mitología, tanto clásica como germánica, en las primeras manifestaciones de la narrativa de mundos imaginarios ha llamado la atención de los más eminentes expertos desde su origen. Sin embargo, se echa en falta un estudio sistemático de dicha influencia en obras contemporáneas como Canción de hielo y fuego de G.R.R. Martin.El presente artículo establece una serie de significativas resonancias míticas en la estructura argumental de dicha obra que, más allá de la mera inspiración, denotan un claro carácter recreativo, sobre estas resonancias, además, se sustenta la trama política y emocional de la obra. Esta recreación mítica supone, por otra parte, su base simbólica. Martin toma la mitología como germen de la historia de su universo imaginario, revitalizando mitos que parecían haber perdido su vigor y sentido pragmático, pero que, sin embargo, recuperan su condición arquetípica y significativa.
"La culpa es de los tlaxcaltecas" de Elena Garro: problema de sus "solución artística" y poética
Authors: Solé Zapatero Francisco Xavier
Published: December 2020

A partir del "Proceso de Aproximaciones Sucesivas-Acumulativas" (PASA), puesto en escena en otro textos, el presente artículo pretender dar cuenta de algunos de los problemas de la "solución artística" y poética de "La culpa es de los tlaxcaltecas" de Elena Garro. Sin embargo, dada la complejidad del texto en estudio, aquí sólo se evidenciarán algunas de las rupturas  que se manifiestan en ella y que muestran la importancia de la lectura propuesta, eludiendo por ahora su entreverada articulación, la cual requiere de un trabajo mucho más extenso. No obstante, con ello basta para mostrar que es una obra profundamente incomprendida,  y no sólo  por las innovaciones  en su configuración poética, producto de la poisición y perspectiva "auto-centrada" y "des-centrada"  (tanto individual como de memoria socio-histórico-cultural) desde donde el Autor configura su poética, de acuerdo con la relación que establece con la posible "respuesta" de su interlocutor, el Lector, es decir, de aquel a quien se dirige, sino por la forma en que se lee y en la que nos ubicamos para hacerlo.
Nuevas aportaciones sobre el Campamento III de Renieblas (Soria): ¿castra de Nobilior o castra de Escipion?
Authors: Morales Hernández Fernando , Morillo Cerdán Ángel
Published: December 2020

La estrecha relación espacial y arqueológica del complejo de campamentos de Renieblas con la circumvallatio escipiónica de Numancia ha generado no poca controversia a lo largo de más de un siglo, derivada de la ausencia de estratigrafías. En el presente trabajo se apunta la posibilidad de que el antiguo Campamento III de la Gran Atalaya de Renieblas, atribuido por Schulten a la campaña de Nobilior de 153-152 a. C., fuera reocupado por Escipión Emiliano como campamento base en la campaña final contra la capital arévaca en el 134-133 a. C. La consideración y comparación de las defensas y estructuras interiores de Renieblas III y su anexo, así como la presencia de algunos materiales, especialmente los numismáticos, vienen a reforzar esta reocupación escipiónica. Esto nos lleva a plantear la hipótesis de que estaríamos ante un campamento legionario bifásico. Por otra parte, la observación a través del análisis de los datos LiDAR nos ha permitido completar el trazado del mencionado anexo del Campamento III por el suroeste.
La enseñanza de la Historia local en el Grado de Primaria con memes: Córdoba
Authors: Guerrero Elecalde Rafael , López Serrano Miguel Jesús
Published: December 2020

Este artículo tiene por objetivo dar a conocer los resultados de una investigación desarrollada en el Grado en Educación Primaria de la Universidad de Córdoba sobre el uso de los memes como recurso didáctico para la enseñanza de la historia local. La tarea consistió en la confección, por el alumnado, de diferentes memes relacionados con la biografías de personalidades del pasado de la ciudad para luego ser compartidos en el grupo privado de Facebook de la clase. Posteriormente,  se les preguntó con un formulario de Google Forms, sobre los contenidos y el diseño de la docencia desarrollada, con el deseo de conocer si este tipo de herramientas son válidas para la formación de los futuros docentes de Educación Primaria.
Periphery as Context: Enlightenment Influences Towards Conceptual Change in Polish-Lithuanian Political Thinking in the Later 18th Century
Authors: Mačkinis Vilius
Published: December 2020

The specific political culture of the Polish-Lithuanian Commonwealth and its changes, leading to state reforms by the end of the 18th century, require a methodological approach, which would allow understanding the flow and interconnectedness of the ideas between wider European and smaller local contexts. Arguing that entangled history approach allows understanding peripheral contexts better, the article presents specific aspects of the Polish-Lithuanian Enlightenment creating the context for conceptual change in political thinking. The context specific details are presented with the analysis of Vilnius University related discourse showing that the Enlightenment ideas were used to achieve certain goals of local improvement.
