This article analyzes the role played by Equatorial Guinean woman within the Fang patriarchal power structure. It seeks to understand how biological differences and social and interpersonal relationships between men and women are constructed in this sociopolitical and cultural system based on the monopolization of power by the man in African society. To carry out this work, the postcolonial theory of Gayatri Spivak, from a perspective of subalternity, has been used, as well as Simone de Beauvoir’s feminist theory to question the ideological relations of domination/subordination that characterize men and women through Ekomo. From these theoretical and analytical approaches, this paper concludes that the Equatorial Guinean woman in Ekomo is not only the victim of marginalization and invisibility, but also of violence and exploitation by the man under the order of the Fang patriarchy. This work provides another way of understanding and perceiving the African woman, not as an enemy of man but as a fusional being.

The artificial creation of human life, machines, robots and androids will be an argument that will make the myth of Prometheus fashionable in a new format, the cinema. The novel Frankenstein or the modern Prometheus, published by Mary Wollstonecraft Shelly in 1818, is the beginning of a series of rereadings of the myth of Prometheus and the precedent for numerous science fiction films of the last decades of the 20th century.Greek mythology has produced three fascinating literary versions of Prometheus (Hesiod, Aeschylus and Plato), reflecting different intentions. Science fiction cinema has made a new reading of this mythical story, but through Platonic interpretation, where the valuation of technique, as the foundation of civilization and progress, emerges.Blade Runner and Blade Runner 2049, with their creation of replicants (Nexus 6 and 9 respectively) are a paradigm of the scientific Prometheus, which highlights the risks of technical progress and the lack of ethics and moral scruples in science.This article analyzes the adaptation of the Promethean myth in these two science fiction films through the continuity of various motifs that coincide with the novel Frankenstein, through a comparative methodology and analysis of the mytheme and its transfictionality.

Práxedes Mateo-Sagasta (1825-1903) –an important figure in the liberal revolution–is related to the resurgence of the press in the complicated context of the century. When the politician came to power (1881), the Ley de Imprenta (1879) was repealed and the Ley Gullón (1833) was drafted. Since 1857 he has been the editor of La Iberia, used to spread his ideology that complements his political activity, since his numerous parliamentary speeches –with good oratory technique– showed mastery of rhetorical persuasion. In the present investigation, two important sagastine facets are studied, with descriptive methodology of integrated heritage, which are oratory and the press. The application of the method offers the rhetorical-linguistic possibilities of the analysis of the corpus of theme speeches on the press. These notes expose the possibilities of the forgotten genre of political discourse, the patrimonial figure of Sagasta stands out as a very good parliamentary speaker. The union of the method and the discourse analysis guidelines offer a new vision to train in heritage education.

This article works with the expressions of pleasure associated with the act of reading and writing through Augustinian rhetoric thinking and poststructuralism. The present research attempts to alleviate the scarce attention traditionally given to feelings as a cognitive tool. Therefore, here we use emotions as instruments to understand texts differently and challenge them from new perspectives. In this case, we work with the emotions provoked by reading activity in two fundamental authors: Saint Augustine of Hippo (354-430) and Jacques Derrida (1930-2004). Focusing on how reading generated different sensations in both writers helps us to understand their fundamental questions: the Augustinian notions of “sign” and “thing” and Derrida’s critique of the hermeneutics of truth. To accomplish this, I employ the methodology developed by the affective turn, in line with the many studies that have found in the historization of emotions an effective stimulus for rethinking the written tradition.

Jovellanos is, for many historians,the most valid symbol of the SpanishEnlightenment. He was also at the time, for a large part of the revolutionary public opinion, the best-known victim of that long-lasting spirit of Spanish fanaticism, then embodied by the absolute monarchy of Carlos IV. Without fully sharing the ideological principles of tolerance, as he did not participate in philosophical relativism in politics or religion, Jovellanos was largely tolerant in attitudes and behaviors and his public activity was nourished by good judgement and calm reformism. This work studies the books and readings in which Jovellanos learned to use the concepts of good judgement and from where he extracted some of his behavioral models. For this, the content of his library is analyzed, as it was in 1778, and the works present in it are reviewed, in which the ideas of moderation and harmony were taking shape from Humanism to the Enlightenment. The readings that Jovellanos himself declares to be doing over the years are also examined, in order to identify the intellectual origin of his practice of tolerance.

Starting from T. Todorov’s conceptionof narratology, as a science thatencompasses and systematizes the knowledge of story theory in its different aspects, this work includes a model of “representation/ comparison” and study of the constitutive and differentiating features of the story – this is, its narrative strata or thedifferent levels of elaboration,  organization and presentation that the text comes to offer – to pose a precise theoretical and structural view of the textual relationship short story/micro-story.

Ensuring a quality, inclusive andequitable education is one of the main objectives established by the Ministry of Social Rights and the 2030 Agenda in Spain. This study tries to contribute with the participation of 160 students in the 2019- 2020 academic year, following the reading parameters through the PLIA Platform, a tool based on the e-portfolio concept ofthe Common European Framework of Reference for Languages. The results showed that PLIA allowed the systematisation of reading work and reduced the effort required by teachers. Furthermore, resultsshowed that PLIA is an adequate resource, since it contributes to the promotion of the quality of the educational process, guaranteeingequal opportunities and democratizingaccess to reading in any language.Finally, the use of this digital tool increased the students’ motivation and their performance.

The fissility is the ability of some rocks to split along relatively smooth surfaces parallel to the bedding. This property observed mostly in fine-grained rocks is particularly expressed in outcrops, where rocks are subjected to weathering processes. Most authors associate the fissility to the abundance of clay minerals and their orientation parallel to the bedding. The horizontal fabric can be promoted by depositional conditions such as sediment composition, quantity of total organic carbon content (TOC) and depositional mechanisms, giving rise to a primary fissility. Alternatively, the alignment of platy minerals can be linked to the burial history of the rock, by processes such as mechanical compaction or secondary mineral growth, resulting in a secondary fissility. The present study aims to identify the main controls of fissility development at the micro- and macroscopic scale in rocks of the Vaca Muerta Formation exposed in the Cerro Mulichinco area and in a 121-meter-long core extracted from a well within the Neuquén Basin. In outcrops, fissility is related to fine-grained laminated facies with low carbonate content, revealing the strong control exerted by lithology. The TOC measurements allow establishing a positive correlation between organic matter content and fissility intensity. Moreover, the analysis of the transgressive-regressive cycles shows that fissility is higher around the maximum flooding surfaces. Regarding their mechanical characteristics, the different interfaces observed in core are classified into first and second-order, the last one including fissility planes. Some of these interfaces evolve from potential (partially open) to effective (totally open) discontinuities in response to changes of stress conditions during the core extraction and due to the stress relaxation through time: weeks (T1), months (T2) and years (T3) after extraction. The time evolution of the effective core discontinuities points out rock intervals that are variably broken and core segments that remain intact. The Drying Alcohol Discontinuities (DAD) methodology reveals potential discontinuities within apparently intact core segments. By using this technique, a 4-class index is established as a proxy for fissility degree. When integrated with geological, petrophysical and geomechanical data, this index enables characterizing the main mechanisms controlling rock fissility that express through discontinuities promoting the loss of competence of a rock. Consequently, this mechanical property is considered to influence the efficiency of hydraulic fracture in shale reservoir completion.

Ash-fall tuffs of the Pliocene-Pleistocene deposits of Humahuaca and Casa Grande intermountain basins, northwestern Argentina, have been differentiated into two groups based on new geochemical and geochronological data which correspond to the tuffs of the Pliocene-Lower Pleistocene alluvial fan deposits dominated by debris flow, deep sandy gravel braided, and shallow ephemeral lake deposits (Uquia and Mal Paso formations), and those recorded in Pleistocene alluvial fans sheet flood deposits. The two clusters of ages recognized: 4.3 to 2.6 Ma, and 2.2-pre 0.8 Ma, corresponding to these tuff groups, are in agreement with pulses of ignimbrite eruptions in the Altiplano Puna Volcanic Complex (APVC), and Southerm Puna calderas located west of the study region. The ash-fall tuffs of both groups are mainly vitreous to phenocryst-poor of rhyodacite-dacite composition with minor andesites to trachyandesites, characterized by 58-69% SiO2 contents, A/CNK 1-1.4, FeO/MgO (0.8-2.8), which plot in the calc-alkaline range. They can be differentiated based on its immobile trace elements ratios as indicated by a slight enrichment in LREE, higher arc affiliation and somewhat higher Sm/Yb ratios in the case of the younger group, although in both Sm/Yb ratios are indicative of sequestration of HREE in residual hornblende. The new geochemical and geochronological data of those ash fall tuffs point to these as chrono-stratigraphic tracers of the Humahuaca and Casa Grande intermountain basins stratigraphy, during the Pliocene-Pleistocene, also as the key to identify their volcanic sources.

The microfossil hosted in the strata of the upper part of the San Juan Formation has been widely studied in several sections to the northward of the Argentinian Central Precordillera. In contrast, the coeval strata at the Los Baños de Talacasto section, in the southern part of the Central Precordillera, have scarce biostratigraphic and sedimentological data. In this work, a conodont association together with single ostracod species are documented for the first time in this section. The record of the Lenodus crassus and L. pseudoplanus zones confirms the Darriwilian age for these beds and accurately correlates them with equivalent strata of the San Juan Formation studied in several sections of the Central and Eastern Precordillera. The microfacies analysis verifies the presence of Nuia síbirica Maslov, 1954, peloids, intraclasts, cyanobacteria, calcareous algae, and a possible microbialite indicating a shallow warm-water subtidal environment, in equatorial to subequatorial climate. This suggests a low latitudes position for Precordillera during the early-middle Darriwilian. The conodont genus Aurilobodus Xiang and Zhang is recognized for the first time from the Precordillera, and the Aurilobodus leptosomatus An specimens are described and illustrated. This genus shows affinities to the warm water in shallow marine environments of North China, Central Asia, South Tibet, western Thailand, Australia, and Newfoundland, suggesting probable ties between Precordillera and these regions. The record of the ostracod Pilla nodospinosa Salas in the study section would agree with the correlation of the top of San Juan Formation with the lower levels of the Las Aguaditas Formation in the Central Precordillera, and also suggests paleobiogeographic links with Eastern Gondwana and Australia regions during the Darriwilian times.
