Published: March 2020

Castel-Minier est un site minier et métallurgique situé au cœur des Pyrénées ariégeoises. De la fin du xiiie siècle au xvie siècle, ses ateliers ont produit de l’argent, du cuivre et du plomb à partir de minerais extraits sur place. Des récentes fouilles ont mis au jour des structures de chauffe et un large corpus d’objets provenant des différentes activités métallurgiques du site. Ce corpus comprend notamment neuf fragments de céramiques métallurgiques. Dans cet article, nous présentons leur étude céramologique ainsi que l’analyse des résidus métalliques présents sur leur surface. D’une part, les résultats rendent compte de la vocation polymétallurgique du site en mettant en évidence la nature des métaux travaillés (plomb, argent ou cuivre) mais également en identifiant les étapes des chaînes opératoires métallurgiques auxquelles se rattachent certaines céramiques, notamment l’affinage de l’argent. D’autre part, ils ont permis d’identifier des stratégies différentes dans le façonnage des céramiques métallurgiques. Ainsi, celles liées au travail du plomb et de l’argent recyclent des pâtes ou du vaisselier domestique, alors que le travail du cuivre requiert une pâte spécifique dont les qualités physiques semblent plus adaptées à la métallurgie.

Published: March 2020

Interest in the nanotechnology invention has been increased among the researcher and industries which lead to many investigations and studies to develop a product with better performance. In this research, hydroxypropyl methylcellulose (HPMC) and poly (vinyl) alcohol (PVA) nanofiber with the ratio 1:1 and the concentration of 5 wt% and 7 wt%, respectively, were successfully fabricated by using electrospinning technique. The HPMC/ PVA was then blended with the different concentration of cellulose nanocrystal (CNC) at 2 wt%, 4 wt%, 6 wt% and 8 wt%. The SEM results of HPMC/PVA/CNC nanofibers shown random orientation fibers with average diameters of 62.28 nm - 252.80 nm. The TGA results showed three major weight loss that prove the decomposotion of HPMC/PVA/CNC was occured with three maximum temperature peaks around 69 °C, 290 °C and 392 °C. As for DSC, the peak intensity of the Tg in the electrospun nanofiber are decreasing as the concentration of CNCs increased might be due to the interfering of the CNC with the crystallization of the polymer causing mobility of the amorphous regions to be higher. Therefore, the study on the thermal properties of HPMC/PVA incorporated with CNCs nanofibers could be a reference for various potential applications.

Published: March 2020

In this study, a renewable phenolic component was synthesized using empty fruit bunch fibers via microwave-assisted liquefaction known as Liquefied Empty Fruit Bunch (LEFB). LEFB can be used as phenolic derivative to replace petroleum-based phenol as it contains aromatic group in lignin that can be used as starting materials to synthesis polybenzoxazine resins. A Lignin-based benzoxazine (L-PBz) has been synthesized using a solventless approach from the reaction of LEFB, furfurylamine as the amine component and paraformaldehyde via Mannich condensation reaction. Two different ratios of LEFB:furfurylamine:paraformaldehyde which are 1:1:1 and 1:1:2 were investigated. The thermal properties and polymerization behavior of the L-PBz were analyzed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), respectively. In addition, cured-polybenzoxazine composites were also prepared by hot-pressing the uncured L-PBz at 250 °C for 4 hours, and the mechanical properties of the composites were assessed through Izod impact strength test. TGA analysis showed that, L-PBz with ratio of 1:1:1 exhibit a high char yield compared to 1:1:2 which is 47% vs 43%, respectively, after being heated until 900 °C. However, L-PBz with ratio of 1:1:2 showed good polymerization behavior compared to 1:1:1 which indicated by the curing temperature 215 °C vs 238 °C. L-PBz composites, which added with cellulose nanocrystal (CNC) fillers have better strength compared with the absence of fillers. As a conclusion, the aromatic structure of lignin in empty fruit bunch fibers has presented a promising alternative to replace petroleum-based phenol in polybenzoxazine synthesis.

Conductive polymer composites (CPCs) have attracted great attention of researchers due to their enhanced properties such as an adjustable electrical conductivity, good processability, good mechanical and thermal properties, etc. CPCs had many potencies for wider application in electronic devices. Poly (lactic acid) or PLA is one of the interesting polymers used in the developing of these new important materials. PLA properties are comparable to the synthetic petroleum-based polymers such as polyethylene terephthalate (PET), polypropylene (PP), etc. This research focuses on studying the rheological and thermal properties of PLA/micro-graphite as a conductive polymer composite which adjustable its electrical conductivity. In this study, the PLA/micro-graphite was prepared through solvent blending method using chloroform. The micro-graphite composition was varied from 0%, 5%, and 10 % (w/w) with different stirring time (30 and 60 minutes) and then, poured in glass mould. In the melt rheology study, the frequency sweep test showed that the complex viscosity (|η*|) of the bio-composite increased with the micro-graphite loading. The same tendency was also found in thermal property and stability. The melting temperature and thermal degradation were slightly increasing. The crystallinity of PLA was influenced by the presence of micro-graphite. In this solvent blending method, the homogeneous distribution of micro-graphite in the bio-composite required at least 60 minutes (stirred at 650 rpm and 60 °C).

Published: March 2020

The objective of this research is to investigate the effect of incorporating graphite filler on mechanical, thermal and morphological properties of wood recycled plastic composites (WrPC). WrPC was prepared using recycled polypropylene (rPP), kenaf core, maleic anhydride polypropylene (MAPP) and graphite filler. The graphite content in WrPC is 3 phr. All materials were premixed manually and fed into a single screw extruder and compression molded to prepare mechanical test specimens. The effect of graphite on tensile properties, impact strength, glass transition temperature (Tg) and morphological properties of WrPC were studied. Tensile strength was increased from 6.81 MPa to 10.07 MPa due to stronger interfacial adhesion between graphite and kenaf/rPP. However, the tensile modulus decreased significantly with the incorporation of graphite. Impact strength of WrPC was increased from 2.48 kJ/m2 to 2.83 kJ/m2 due to the present of graphite that gave effective distribution of applied stress and increase resistance of crack propagation. DSC results indicated that Tg of graphite/WrPC is comparable to WPC at 163°C. The internal structure of WrPC showed the addition of graphite had filled the voids and lead to smooth morphology.

Ananas
co
mosus plants produced enzyme called bromelain which acts as an anti-browning agent with the enzymatic inhibition to inhibit fruits browning thus prolong the life span of fruits. The properties are also discovered in aloe vera plant extract which act as an edible coating that can provide nutrients whilst improving anti-browning agent reaction. In the present study, we aimed to elucidate the inhibitory properties of bromelain and aloe vera extract to the enzymatic browning reaction of fresh pear slices. Our result showed that the combination of bromelain and aloe vera extract are able to reduce browning reaction of pear slices by inhibiting the polyphenol oxidase (PPO) reactions. Hence, this study suggest that bromelain and aloe vera work well as anti-browning agents and suitable to be used as natural food additives that can provide nutrients while maintaining food quality.

Acetosolv technique is considered as one of the best alternative way to extract technical lignin from biomass as it has high efficiency and environmentally friendly. In this study, microwave-assisted acetosolv technique were used to extract lignin from oil palm empty fruit bunch (OPEFB) in the presence of 3% sulfuric acid catalyst reacted at various temperature. The yield of the extracted acetosolv lignin were calculated using modified Technical Association of the Pulp and Paper Industry biomass composition analysis (TAPPI) method. The result showed that, as the temperature increased from 90 to 110 °C, the yield of lignin extracted also increase from 43.07 to 76.98%. The presence of guaiacyl and p-coumarate indicates the presence of active sites at C-3 and C-5 of aromatic ring for polymerization reactions. Scanning Electron Microscopy images showed that removal of lignin are intensified as the microwave-assisted acetosolv temperature increased.

Glycosaminoglycans (GAGs) are long unbranched polysaccharide that composed of repeating disaccharide units. They are classified into heparan sulfate (HS), heparin, chondroitin sulfate (CS), dermatan sulfate (DS), keratan sulfate (KS) and hyaluronic acid (HA). During the last decade, demand of GAGs were getting increased due to their potential uses. Vertebrate animal, commonly cartilaginous mammalian tissue, were potential producer of GAGs and have the higher number of biological activities extracted from sea bass waste. Sea bass waste from Lates calcarifer was used as the raw material to extract crude GAGs. Different part of sea bass waste such as, gills, viscera and air bladders were used. The higher content of crude GAGs in sea bass waste was used in cytotoxic and inflammatory study. Different concentration of extract GAGs from gills were used ranging between 0.16-20 mg/mL. GAGs from sea bass waste (gills) showed dose-dependent cytotoxic activity towards MCF-7 cell line in lower concentration. Meanwhile, for anti-inflammatory study GAGs from sea bass waste (gills) showed dose-dependent manner and also reduce NO production in LPS-stimulated cells. This research study concluded that, GAGs from sea bass waste are the alternative source that can be used for cancer and inflammation study.

Authors: Bakar Nurul Huda Abu , Ismail Jamil , Chong Kwok Feng
Published: March 2020

Corrosion performance of graphene oxide (GO) coatings from different sheets sizes in 3.5 wt% NaCl solution was investigated. The GO dispersion was subjected to 5 and 10 hours of ultrasonication before electrophoretically deposited (EPD) onto the copper substrate. It was found that the EPD-GO coating from smaller sheets (10h ultrasonication) possess hydrophobic, thinner film and smooth surfaces. It is suggested that the corrosion performance of the coating from smaller GO sheets is improved due to the surface texture and compactness of the coating as compared to the larger GO sheets.

Published: March 2020

Carbon capture and storage (CCS) is one of the method in reducing carbon dioxide (CO2) emissions into the atmosphere. CO2 capturing using calcium oxide (CaO) solid sorbents has been considered as an advanced concept for CO2 capture and recovery. However, the adsorption capacity of CaO decreases during repeated adsorption/desorption cycles. The stability of Ca-based sorbents during cyclic runs can be achieved via the incorporation of inert support materials. Among the available inert materials, MgO is most promising for CO2 due to high stability and a high Tammann temperature. Most of Ca- based MgO hybrid adsorbent synthesis methods sorbent come with its own limitations which are longer synthesis duration and complex or multistep methods. In this research, Ca-based MgO hybrid adsorbent was prepared via two-step method. Calcium acetate and magnesium nitrate as precursor had dissolved in water, follow by addition of ethanol. The mixture then became gelated and proceeded for calcination at 550°C and 650°C. The prepared sorbent was characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) and fourier transfer infrared spectroscopy (FTIR). The XRD analysis of the Ca-based MgO hybrid adsorbent showed the existence of MgO,CaO and CaCO3. FTIR analysis showed presence of Ca─O bond and Mg═O bond. The morphology of the hybrid adsorbent was found to be spherical to granular shape and agglomerated. The Ca- based MgO hybrid adsorbent structural and morphological shows great potential for CO2 capturing capacity over multiple carbonation cycles for CO2 capturing application.

Published: March 2020

Enhancing the optical performance of rare earth doped binary inorganic glasses is an ever-demanding quest. Samarium (Sm3+) doped zinc tellurite glasses containing Manganese (Mn) nanoparticles (NPs) with composition (59-x)TeO2-20ZnCl2-10ZnO-10Li2O-1Sm2O3-(x)Mn3O4, where x = 0 to 0.06 mol% are prepared by melt quenching technique. The role played by Mn NPs in enhancing the optical behaviors are analyzed and discussed. The XRD patterns confirm the amorphous nature of the glass. The UV-Vis-NIR spectra reveal seven prominent absorption bands of Sm3+ ions. The photoluminescence spectra display four peaks corresponding to 4G5/2→6H5/2, 4G5/2 →6H7/2, 4G5/2→6H9/2 and 4G5/2 →6H11/2 transitions. An enhancement in the luminescence intensity is observed up to 0.05 mol% concentration of NPs and the intensity quenches beyond it. The enhancement is attributed to local electric field effect of NPs in the proximity of Sm3+ ion. Our results on improved optical response via precise control of NPs contents may be useful for the development of solid state lasers and amplifiers.

Background: Same-day discharge, defined as discharge from the hospital within 24 h of surgery, has been shown to be safe for joint arthroplasty. We examined demographic and clinical factors associated with same-day discharge and unplanned readmission following shoulder arthroplasty in adult patients.Methods: Utilizing data from the American College of Surgeons National Surgical Quality Improvement Program database, we extracted information of all patients that underwent shoulder arthroplasty. The primary and secondary outcome of interest was same-day discharge and 30-day unplanned readmission, respectively. We utilized multivariable logistic regression to identify covariates associated with these outcomes. Results: There were 17,011 patients analyzed when identifying predictors for same-day discharge. There was an increase in same-day discharge from 2007 to 2016. The odds of same-day discharge were significantly better for males (P < 0.001). The odds of same-day discharge was significantly decreased for every 10-year increase in age and for patients with insulin dependent diabetes, poor functional status, chronic obstructive pulmonary disease, congestive heart failure, bleeding disorder, and comorbidity burden (all P < 0.001). There were 14,276 patients analyzed for hospital readmission. The odds of unplanned readmission were significantly higher for every 10-year increase in age and for patients with poor functional status, congestive heart failure, bleeding disorder, and higher comorbidity burden (all P < 0.001). Conclusions: The results of this study show that preoperative comorbidities and advanced age reduce the odds of same-day discharge. Risk stratification, preoperative optimization, and coordinated care after surgery may be helpful to optimize patients for same-day discharge.
The cognitive biases of human mind in accepting and transmitting religious and theological beliefs: An analysis based on the cognitive science of religion
Authors: Biabanaki Sayyed M.
Published: March 2020

The cognitive science of religion (CSR) is an emerging field of cognitive science that gathers insights from different disciplines to explain how humans acquire and transmit religious beliefs. For the CSR scholars, the human mental tools have specific biases that make them susceptible to acceptance and transmission of religious beliefs. This article examines the characteristics of these biases and how they work, and shows that although our innate cognitive tendencies make our minds generally receptive to religion, they do not explain the emergence and endurance of specific religious beliefs in a particular culture. We will also show that although advocates of CSR study religion as a ‘natural’ phenomenon, and seek to discover the natural causes of the formation, acceptance, transmission and prevalence of religious beliefs, their efforts do not lead to decrease the validity of religious beliefs and rejection of ‘non-natural’ explanations of religious beliefs.

On self-similar finite $p$-groups
Authors: Babai Azam , Fathalikhani Khadijeh , Fernández-Alcober Gustavo A. , Vannacci Matteo
Published: March 2020

In this paper, we address the following question: when is a finite

p

-group

G

self-similar, i.e. when can

G

be faithfully represented as a self-similar group of automorphisms of the

p

-adic tree? We show that, if

G

is a self-similar finite

p

-group of rank

r

, then its order is bounded by a function of

p

and

r

. This applies in particular to finite

p

-groups of a given coclass. In the particular case of groups of maximal class, that is, of coclass 1, we can fully answer the question above: a

p

-group of maximal class

G

is self-similar if and only if it contains an elementary abelian maximal subgroup over which

G

splits. Furthermore, in that case the order of

G

is at most

p^{p+1}

, and this bound is sharp.
Weighted Blanket Use: A Systematic Review

Published: March 2020

Importance: Sensory integration modalities, such as weighted blankets, are used in occupational therapy practice to assist with emotional and physical regulation. However, the research related to the use and effectiveness of weighted blankets is sparse.

Objective: To identify, evaluate, and synthesize the current literature to help develop the impetus needed to launch a research study into the effectiveness of using weighted blankets to decrease anxiety and insomnia.

Data Sources: A literature search was conducted between January 23, 2018, and March 1, 2018. Databases and sites included the Cochrane Library, PubMed, PsycINFO, CINAHL, OTseeker, Web of Science, and Nursing Reference Center Plus. Search terms included weighted blanket, deep pressure, and occupational therapy as well as combinations of these terms.

Study Selection and Data Collection: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were included if the study used weighted blankets as the modality of deep pressure stimulation. Data from presentations, conference proceedings, non–peer-reviewed literature, dissertations, and theses were excluded.

Findings: Only 8 studies were included: 4 Level I, 2 Level III, and 2 Level IV studies. The outcomes of these studies suggest that weighted blankets have the potential to be beneficial in limited settings and populations.

Conclusion and Relevance: Weighted blankets may be an appropriate therapeutic tool in reducing anxiety; however, there is not enough evidence to suggest they are helpful with insomnia.

What This Article Adds: Evidence-based research on the effectiveness of weighted blankets in reducing anxiety and insomnia is sparse. More research is needed to define guidelines for the use of weighted blankets in clinical practice and to investigate the underlying mechanism of action. This systematic review can be used to begin an investigation of the use of weighted blankets for larger and more diverse populations.

The effect of interactive ozone chemistry on weak and strong stratospheric polar vortex events
Authors: Oehrlein Jessica , Chiodo Gabriel , Polvani Lorenzo M.
Published: March 2020

Abstract. Modeling and observational studies have reported effects of stratospheric ozone extremes on Northern Hemisphere spring climate. Recent work has further suggested that the coupling of ozone chemistry and dynamics amplifies the surface response to midwinter sudden stratospheric warmings (SSWs). Here, we study the importance of interactive ozone chemistry in representing the stratospheric polar vortex and Northern Hemisphere winter surface climate variability. We contrast two simulations from the interactive and specified chemistry (and thus ozone) versions of the Whole Atmosphere Community Climate Model, designed to isolate the impact of interactive ozone on polar vortex variability. In particular, we analyze the response with and without interactive chemistry to midwinter SSWs, March SSWs, and strong polar vortex events (SPVs). With interactive chemistry, the stratospheric polar vortex is stronger, and more SPVs occur, but we find little effect on the frequency of midwinter SSWs. At the surface, interactive chemistry results in a pattern resembling a more negative North Atlantic Oscillation following midwinter SSWs, but with little impact on the surface signatures of late winter SSWs and SPVs. These results suggest that including interactive ozone chemistry is important for representing North Atlantic and European winter climate variability.
Effects of atmospheric circulations on the interannual variation in PM2.5 concentrations over the Beijing-Tianjin-Hebei region in 2013–2018
Authors: Wang Xiaoyan , Zhang Renhe
Published: March 2020

Abstract. The Chinese government has made many efforts to mitigate fine particulate matter (PM2.5) pollution in recent years by taking strict measures on air pollutants reduction, which has generated the nationwide improvements in air quality since 2013. However, under the stringent air pollution controls, how PM2.5 concentration varies and how much the meteorological conditions contribute to the interannual variations in PM2.5 concentrations are still unclear, which is very important for the local government to assess the emission reduction of previous year and adjust mitigation strategies of next year. The effects of atmospheric circulation on the interannual variation in wintertime PM2.5 concentrations over the Beijing-Tianjin-Hebei (BTH) region in the period of 2013–2018 are evaluated in this study. Generally, the transport of clean and dry air masses and unstable boundary layer working with the effective near-surface horizontal divergence or pumping action at the top of the boundary layer benefit for the horizontal or vertical diffusion of surface air pollutants. Instead, the co-occurrence of a stable boundary layer, frequent air stagnation, positive water vapor advection and deep near-surface horizontal convergence exacerbate the air pollution. Favorable circulation conditions lasting for 2~4 days are beneficial for the diffusion of air pollutants, and 3~7 days of unfavorable circulation events exacerbate the accumulation of air pollutants. The occurrence frequency of favorable circulation events is consistent with the interannual variation in seasonal mean PM2.5 concentrations. There is better diffusion ability in the winters of 2014 and 2017 than in other years. A 76.5 % of the observed decrease in PM2.5 concentrations in 2017 over the BTH region could be attributed to the improvement in atmospheric diffusion conditions. It is essential to exclude the contribution of meteorological conditions to the variation in interannual air pollutants when making a quantitative evaluation of emission reduction measurements.
Water stable isotopes (δ2H and δ18O) in the Peninsula of Yucatan, Mexico

Published: March 2020

Abstract. The hydrogen and oxygen isotopic composition of water is a very important tool to estimate water balance, groundwater recharge, and evaporation. Water isotopes have been used to increase our understanding of the distribution and amounts of renewable and non-renewable groundwater. Isotopic data from precipitation and groundwater is available in much of Mexico but there is little information from the Peninsula of Yucatan, an area heavily relying in groundwater in which current estimates of groundwater availability are uncertain. In this paper, we compiled published and unpublished δ2H and δ18O data in meteoric (waters derived from precipitation), ground- and pore-waters, to obtain a regional meteoric water line (RMWL) expressed by the equation δ2H = 8.1846 δ18O + 10.289. The data suggest that precipitation originates in convective systems, low-pressure events, moisture from frontal events, and from re-condensed moisture. The evaporation lines from groundwater suggest mixing of water with different isotopic composition, but also provide clues to recent meteoric water rapid recharge, likely from rain events of great intensity. We present a groundwater isoscape of the Peninsula of Yucatan and finally address the lack of conciliation between hydrogeology and groundwater management.
La alternancia de las preposiciones ‘por’ y ‘de’ en las construcciones causales
Authors: Funes María Soledad
Published: March 2020

El presente trabajo se propone describir, a partir de contextos auténticos, las construcciones causales (CC) introducidas por la preposición ‘de’, en comparación con las construcciones causales introducidas por la preposición ‘por’, en los contextos donde alternan. Se tienen en cuenta los siguientes parámetros de análisis: el tipo de esquema verbal, el tipo de actante(s) involucrado(s) y el tipo de causa introducida. Se espera aportar evidencia empírica a la siguiente hipótesis: las CC introducidas por ‘de’ tienden a aparecer en colocaciones (manifestadas en esquemas intransitivos con verbos de cambio de estado), con actante ‘paciente cambio de estado’ e introduciendo causas reales. En contraposición, las CC introducidas por la preposición ‘por’ aparecen en esquemas verbales transitivos, con actante sujeto ‘agente’, sin constituir colocaciones. Para comprobar las hipótesis, se analizará un corpus oral del español de Buenos Aires, siguiendo una metodología cualitativa y cuantitativa.
La experiencia del cautiverio como punto de partida para el desarrollo de una identidad nacional híbrida en dos novelas argentinas contemporáneas: El entenado de Juan José Saer y Finisterre de María Rosa Lojo

Published: March 2020

El entenado (1988) de Juan José Saer y Finisterre (2005) de María Rosa Lojo son novelas históricas contemporáneas que dialogan con los textos canónicos de la fundación nacional de la Argentina poniendo en tela de juicio la “verdad” singular y la reducción identitaria del mito del hombre blanco en ese país. Dichas narraciones recuperan la identidad indígena excluida del discurso oficial hegemónico mostrando cómo de la experiencia del cautiverio del sujeto europeo entre los indígenas se desarrolla una identidad nacional híbrida.
La influencia prerrafaelita en Rubén Darío: "El reino interior"
Authors: Sales Delgado Carmen
Published: March 2020

El prerrafaelismo, movimiento artístico y estético iniciado por Dante Gabriele Rossetti, pintor inglés e integrante de la “hermandad prerrafaelita” fundada en 1848 y en la que se hermanaban estrechamente la pintura y la poesía, se halla muy presente en la obra de Darío Los Raros. El interés de Rubén Darío por la pintura viene dada por la estrecha relación que mantuvo toda su vida con diferentes pintores y toda clase de artistas en las diferentes ciudades en las que vivió: Santiago de Chile, Buenos Aires, Madrid y París. Sin embargo, será su relación con el crítico chileno de arte Pedro Balmaceda, la que lo llevaría, desde una edad temprana, a reflexionar sobre cuestiones estéticas. Rubén Darío, desde Azul…, se inspira continuamente en la pintura para escribir su obra, valora por encima de otros, a los pintores primitivos italianos, y comparte los gustos de los prerrafaelitas y simbolistas. Al leer la obra de Darío puede apreciarse cómo se establece la expresión conforme a una disposición plástica, esto es, el contenido poético parece disponerse con un criterio de cuadro, un retablo: paisaje, figura humana, vibración de colores, disposición de objetos, seres y perspectivas se hallan en relación directa con la pintura. En muchas ocasiones, los poemas de Darío vienen dados por la contemplación de cierta obra de arte que causa en el pintor una profunda impresión y de la que éste intenta hacer una transposición en poesía. Sin embargo, no siempre se inspira en una obra en concreto, sino que las imágenes, las obras que contempla en exposiciones y las ilustraciones que observa en las revistas quedan en su mente y al unirse con el tema del alma, crean imágenes representativas de la obra de Darío.
Ciudad abierta / Ciudad cerrada: La urbe como espacio generador del relato en la primera narrativa onettiana
Authors: Amatto Alejandra Giovanna
Published: March 2020

En este trabajo se analizan los diferentes recursos técnicos y los elementos narrativos renovadores que emplea Juan Carlos Onetti (1909-1994) en sus primeros relatos: “Avenida de Mayo-Diagonal-Avenida de Mayo”, “El obstáculo” y “El Posible Baldi” que exponen un problema central de la época moderna: la organización dicotómica de la ciudad bonaerense vista a través de las acciones de los protagonistas, quienes se cuestionan si ésta es, realmente o no, un espacio que multiplica las posibilidades de ensoñación.

This paper discusses the different technical resources and innovative narrative elements that Juan Carlos Onetti (1909-1994) employs in his first stories, "Avenida de Mayo Avenida Diagonal of May", "The obstacle" and "Possible Baldi". In them a central problem of modern times is exposed: the dichotomous organization of the Buenos Aires city viewed through the actions of the protagonists, who question whether it is really a space that multiplies the possibilities of dreaming or not.

La representación de la “chola” limeña en la narrativa (¿light?) de Jaime Bayly
Authors: Aguiló Mora Francisca
Published: March 2020

En este ensayo se analizará la representación de las identidades femeninas andinas en la narrativa de Jaime Bayly y se argumentará que dicha representación sigue relegada a posiciones inferiores e inferiorizadas, además de estereotipadas. En el ámbito doméstico, son las empleadas del hogar; en la calle, las prostitutas; y en la sierra, siguen siendo las salvajes, sucias, borrachas e inmorales. Se cuestionará la justicia que esta representación hace de la mujer andina y se recalcará la importancia y trascendencia que conlleva el hecho de que esta imagen sea ofrecida en obras literarias de carácter “popular” e internacional como las de Bayly. Además, se defenderá que en la sociedad limeña, el “problema del indio” (en palabras del filósofo marxista Mariátegui) no es únicamente un problema de carácter biológico sino en mayor grado un problema económico, de clase y status social, de cultura y de prácticas culturales, de lengua, geografía, educación y hasta de carácter personal. Finalmente, se remarcará el carácter novedoso en la historia literaria peruana del tratamiento que Bayly lleva a cabo de la homosexualidad en personajes masculinos de clase media-alta, aunque se enfatizará de igual modo la relación de dominación y de nula solidaridad entre estos sujetos, oprimidos por su sexualidad, frente a la mujer “chola” en Lima, oprimida por su género, etnia y clase social. En definitiva, la ya histórica escasez de la propia voz de la mujer indígena en la literatura peruana y su representación unas veces irreal otras tantas injusta sigue teniendo lugar en la narrativa de Bayly.
The aim of this paper is to analyze how Andean female identities are represented in the narratives by the Peruvian writer and journalist Jaime Bayly, arguing that these female characters continue being stereotyped and represented as the occupiers of the lowest and lowered positions in society: in the domestic sphere, they are the maids; in the street, the whores; and in the mountains, they keep being portrayed as savage, dirty, drunkards and immoral. More precisely, it is my main focus to question the importance of how fair the representations of the female indigenous characters are in Bayly’s novels, considering their popularity and international renown. Also, the novelty in the treatment of the Peruvian male middle-class homosexual will be emphasized but also the relation of domination and the lack of solidarity between this subject, frequently discriminated due to his sexuality, and the “chola”, commonly discriminated due to her gender, ethnicity and social class. Finally, it will be examined how in the current Perú, especifically in Lima, the “problema del indio”, although deriving from ethnicity questions, is more an issue of economic matters, class and social status, culture and cultural practices, language, geography, education and even personal questions.In short, the traditional lack of the Andean women‘s voice in the history of Peruvian literature and their unfair and unreal representation continue to occur in Jaime Bayly’s narratives.
Masculinización y virilización de la escritura de la mujer de vanguardia: el caso de Estación. Ida y Vuelta y El Personaje Presentido
Authors: Paris-Huesca Eva
Published: March 2020

El presente trabajo examina los diferentes procesos por los que la escritora española se enfrenta al mundo masculino del periodo de las vanguardias y cómo lucha por formar parte del movimiento literario de vanguardias. En primer lugar, analizo la figura de Rosa Chacel, una de las pocas escritoras consideradas por el canon literario masculino de la época, y su novela Estación. Ida y Vuelta (1930). Seguidamente, estudio el caso de Concha Méndez, una de las figuras más olvidadas de todas las modernas, y su obra teatral El personaje presentido (1931). La elección de estas dos obras remite al hecho de que cada una de ellas recurren dos mecanismos diferentes para establecer una filiación con este movimiento. Mientras que Chacel plasma en su novela su gran capacidad intelectual y literaria a través de una voz narrativa que sufre un proceso de masculinización, la obra teatral de Méndez es una clara expresión de la mujer moderna que subvierte el modelo patriarcal de femineidad y adopta una imagen más virilizada de la mujer.
This paper examines the various processes by which the Spanish female writer faces the male world of the avant-garde period and how they struggle to join its literary movement. First, I analyze the figure of Rosa Chacel, one of the few female writers considered by the (male) literary canon of the time, and her novel Estación. Ida y Vuelta (1930). Next, I study the case of Concha Méndez, one of the most neglected “modernas”, and her play El personaje presentido (1931). The choice of these two writers and their works refers to the fact that each draw different mechanisms to establish an affiliation with the cultural movement. While Chacel´s novel illustrates her great literary and intellectual capacity through a narrative voice that undergoes a process of masculinization, Méndez´s play is a clear expression of the modern woman who subverts the patriarchal model of femininity and takes a more “virile” picture.

Authors: Garcia-Olano Ramiro
Published: March 2020

En este trabajo analizo el film de Pedro Almodóvar, Pepi, Luci, Bom y otras chicas del montón (1980) en relación al cómic underground español surgido a principios de los años 70 y que hizo eclosión en la primera mitad de la década del 80 del pasado siglo. Mi principal objetivo es ilustrar la influencia que este fenómeno cultural tuvo en las primeras películas de Almodóvar.
In this work I analyze Pedro Almodovar's film Pepi, Luci, Bom y otra chicas el montón (1980) in relation to the Spanish underground comic that emerged in the early 70 and consolidated during the first half of the 1980s.

Influence of Hate Speech on Public Perception of Presidential Candidates’ Credibility During the 2015 Presidential Election in Nigeria
Authors: Ogbonna Christian Alozie , Okoro Nnanyelugo , Wogu Joseph O.
Published: March 2020

The study examines the influence of hate speech on public perception of presidential candidates’ credibility during the 2015 presidential election in Nigeria. The study was guided by two research questions. A descriptive survey design was adopted for the study using 72,001, 204 eligible registered voters in the six geo-political zones of Nigeria. 600 questionnaires were distributed and 518 were returned for analysis through multi-stage sampling. The research questions were answered using mean and standard deviation, while the hypotheses were tested using Pearson – chi-square test at 0.05 level of significance. Findings reveal that the extent to which voters were aware of hate speech against a political opponent during the 2015 presidential election in Nigeria was high. The findings further show that one of the factors that influenced hate speech against a political opponent during the 2015 presidential election in Nigeria was the political affiliation of voters. Concerning the null hypotheses, findings indicated that there was no significant relationship among the responses of the electorate in the six geo-political zones on the factors that influenced hate speech during the 2015 presidential election in Nigeria. A significant relationship was also not found on how hate speech influenced public perception of presidential candidates during the 2015 presidential election in Nigeria. The study recommends that politicians, political parties as well as their supporters should be cautioned on using social media to post hate speech, inciting messages, attack opponents, spread false news. The Independent National Electoral Commission (INEC) should propose to the National Assembly to enact laws in the electoral act that will make the use of hate speech for campaign purposes a punishable offence in the country.
Basic Law: Israel as the Nation-State of the Jewish People: Lessons for Particularistic and Universalistic Constitutional Legitimation
Authors: Harel Alon
Published: March 2020

The ‘Basic Law: Israel as the Nation-State of the Jewish People,’ passed by the Knesset on July 19, 2018. This Article describes the main provisions of the Basic Law; it discusses some of the past history leading to the legislation. It also provides some evaluation as to its effects and speculations concerning its future. Last I use this basic law to make a broader point concerning constitutional legitimation. More specifically I argue that there are two ways to gain constitutional legitimacy: representational and reasons-based. While particularistic values such as the ones entrenched in the basic law gain legitimacy from representation, universalistic values need not rest on representation. I conclude by arguing that given the failure to gain consensual support for the basic law it is an illegitimate attempt to entrench particularistic values in a divisive society. It is only by representing the public as a whole that this law can gain constitutional legitimacy.
Harmonization of the Ukrainian Legislation with the Legislation of the European Union with Regard to Trade Defence
Authors: Lokshyna Iuliia
Published: March 2020

The issue of the necessity of approximation, adaptation or harmonization of the Ukrainian legislation with the EU legislation has been tackled by a number of scholars in Ukraine. A number of normative documents also paid considerable attention to this issue in general. However, there is still an issue of defining the most suitable term which would better purpose bringing legislation into conformity with the requirements of the EU. According to some scholars the notion “harmonization” could better reflect this process. This view is also shared by the author of this article. The article also discusses the importance and the need to pass new draft laws in the field of trade defence in Ukraine, in particular, regarding anti-dumping, countervailing measures and safeguards. Since some of the new articles correspond to similar provisions in the EU directives, this is viewed as an important step to harmonize the Ukrainian legislation with the legislation of the European Union in this sphere.
