Popular actors’ comedy: Reception and influence, Italy–Argentina
Authors: Rodríguez Riva Lucía
Published: January 2022

During the 1950s, Italian film releases increased exponentially in Buenos Aires. This growth occurred not only as a result of the popularity of this type of cinematography around the world but also because of the interest that it produced in local spectators. In this article, I map a quantitative overview about the arrival of this category of cinema to Buenos Aires. Next, I focus on a key aspect: the reception of commedia all’italiana (‘comedy Italian style’). Then, I delve into the kind of comedy in which the comedian occupies the centre of the mise en scène (as Totò or Alberto Sordi). The hypothesis that guides this article is that popular actors, both in Italian and Argentine films, constitute a key issue that allows one to see the continuity between both types of cinematography (through appropriations and reconfigurations of its procedures), as it also allows one to understand the way in which the represented worlds were projected to popular audiences.

The Impact Of Various Primary Tillage Methods On The Yield Components Of Dry Bean
Authors: Monostori Tamás , Tóth Gergely , Bordé Ádám , Jakab Péter , Láng Vince
Published: January 2022

In Hungary, dry bean (Phaseolus vulgaris L.) has been being popular as food and even as kitchen garden crop for centuries but currently only 20% of the annual domestic consumption is produced by the Hungarian agriculture, with the missing 80% coming from import. Improvement of production technology adapted to the new varieties of higher yield potential can contribute to the increase in domestic production. In our experiment, no significant differences could be found between the yield component and yield data of inversion (2.66 tons ha-1) and non-inversion (2.62 tons ha-1) tillage methods. Strip-tillage, however, resulted in higher values for almost all parameters compared to the other two methods. In the case of yield per plant, the difference was significant (24.35 vs. 18.33-18.57 grams ha-1). As the plant density was significantly lower for strip-tillage, despite the significantly higher yield per plant, the yield per hectare results became the lowest (1.39 tons ha-1) here. From the conditions detected after emergence, it was obvious that the harmonization of strip-tillage and sowing was not perfect. As the higher yield component and yield per plant data can be explained both by the lower plant density and the superiority of strip-tillage, the repetition of the experiment is essential.

The outbreak of the coronavirus pandemic (COVID-19) first occurred in late December 2019 at the Hunan Seafood Market in Wuhan, China, and was declared an international public health emergency in a matter of weeks by the World Health Organization. The coronavirus disease (COVID-19) affects every area of human life, including the environment. Measures are taken to control the spread of the virus and the slowdown in economic activities have significant positive effects on the environment. Through this study, the authors intend to track the impact caused by the COVID-19 pandemic on the environment by analyzing the available scientific literature. The study indicates that the pandemic situation significantly improves air quality in various cities around the world, reduces greenhouse gas emissions, reduces water pollution and noise, and reduces pressure on tourist destinations, which can help restore ecological systems. It is noted that there are some negative consequences of the pandemic, such as the increase in medical waste through the use and disposal of disinfectants, masks, and gloves but also the burden of untreated waste that endangers the environment continuously. It seems that shortly after the pandemic the economic activities will return and the situation could change. Therefore, this study highlights the potential positive impacts of the pandemic on the environment in the long term. It is expected that the correct implementation of the proposed strategies can be useful for the global sustainability of the environment.

Published: January 2022

This study is on the fall and readability of electronic leg tags, plastic ear tags and electronic ear tags used in 2 flocks of goats. Honamlı and Turkish Hair goat flocks were followed for 4 months and bred under different conditions. While the flock of Honamli goats went to pasture every day, the Turkish Hair goats remained indoors. It was found that the leg tags fell from 5 goats in the Honamli flock (96%), while none fell in the Turkish Hair flock. Plastic ear tags attached to goats were found to have fallen from 11 goats (92%) in the Honamli flock and 7 goats from Turkish Hair goat flock (90%). The readability of electronic leg tags, plastic ear tags and electronic ear tags used in goats for 4 months was determined as 100%. It is useful to carry out research on the use of electronic leg tags as an alternative option for goat breeding for identification purposes, with different trial groups formed on animals of different ages and different legs.
Case Study on the Registration of Nagykun Rice PGI
Authors: Jantyik Lili
Published: January 2022

With various producer subsidies and giving more information for the consumers, at least a part of the European rice market can be independent of the Asian market. The consumer encounters more and more information on the packaging of food products, among others, the GI label. Geographical Indications contain information on both the origin of the food and the quality associated with the origin. The Nagykun Rice Consortium in Hungary aimed at the European Union geographical indication to highlight the values of Nagykun rice. There were several reasons for the demand for PGI designation. The 2013 Land Act stipulates that those who are engaged in the production of GI product are entitled to pre-emption, so one of the reasons was to keep the lands what they use already or be the one who can buy a new one first. Another reason was that they had been using organic label for several years, so based on their experience, they were also aware of the marketing opportunities of the new label. Important features of Nagykun rice for consumers are the extremely low level of arsenic and the fact that the product is 100% gluten free. The introduction of the organic label was a good example of increasing the price and, as a result, producers can hope that the PGI label can also increase the price among conscious consumers in long-term. The PGI registration process itself is relatively long, but government bodies have proven to be supportive and helpful. The PGI label can be a long-term profitable investment in the Hungarian rice sector. The case of the Nagykun rice consortium can be a good example not only for other rice producers, but also for producers of other agricultural products.

Published: January 2022

Fusarium head blight (FHB), primarily caused by a fungal plant pathogen Fusarium graminearum, is a devastating disease of wheat and other cereals. FHB reduces yield, but also the quality and feeding value of the crop. The fungus produces the mycotoxin deoxynivalenol (DON) that poses a significant threat to the health of domestic animals and humans. In 2019 Fusarium epidemic occurred not only the southern and eastern parts of Hungary, but affected other area of Central Europe. The mycotoxin patterns varied tremendously, depending on the geographic area, different resistance levels of wheat genotypes, weather and soil conditions and cropping factors. In this survey 192 samples of different bread wheat (Triticum aestivum L.) genotypes from three geographically different regions were tested for DON toxin contamination by HPLC-MS method. Average levels of mycotoxin contamination 3.80 mg/kg; it is three times higher than the European maximum limit for unprocessed cereals intended for human consumption. The content range is very wide (0.15 – 20.71 mg/kg), 76% of the samples exceeded the EU risk threshold level.

Published: January 2022

The purpose of study was asses the genetic diversity of soybean varieties by SSR markers and investigate their productivity formation as affected by organic fertilizer, growth regulators and moisture retainer treatments in the Forest-Steppe zone of Ukraine. The effects of agronomical practices were assessed based on yield, protein and oil content. The study was carried out during 2016-2018. As result it was found that the most similar varieties based on 4 SSR markers were varieties with genetic distances 1.73. The most different was Aliaska variety with genetic distances 3.16-3.87. Hieba, Kano and Ustia varieties, which are early-season varieties, were distributed in different clusters. It was determined that maximum of yield was obtained for Kano variety with combining moisture retainer, organic fertilizer and growth regulator “Vermystym D”. The highest protein content in studied varieties was determined in case of combining organic fertilizer and growth regulators. The maximum of oil content was noted in Ustia and Kano varieties with application moisture retainer, organic fertilizer, growth regulators “Vermystym D”. Thus, the biological features and applied nutrition affected studied indicators.
Increasing the number of robotic-arm assisted total hip arthroplasty operations performed on an operating list decreases time per case
Authors: Pagkalos Joe , Wainwright Thomas , Middleton Robert
Published: January 2022

Background and Objectives

The introduction of robotic arm-assisted THA may have a significant effect on operating room efficiency. The objective of this study was to investigate the effect of the operating list case load in robotic arm-assisted THA focusing on operating room utilisation.

Methodology

Only cases performed in lists consisting exclusively of conventional primary THA or exclusively robotic primary THAs were included. All patients underwent posterior approach hybrid THA by a single surgeon in a single operating room. The anaesthetic and intra-operative protocols were identical. List duration was defined as the interval from the arrival of the first patient to the operating room department until the last patient entered the recovery area.

Results

A total of 246 primary THA cases (165 robotic arm-assisted, 81 conventional) were included in this retrospective cohort study. The median number of cases per list for robotic THA was 3 (IQR 2,4) and for conventional THA 3 (IQR 3,4).

The mean session duration in lists consisting of four robotic arm THAs was 544 minutes and for four conventional THAs this was 414 minutes. In multiple robotic arm-assisted THA operating lists, the session duration/THA reduced with increasing list volume (Two THA list: 144min/THA, six THA list: 129 min/THA). This finding was upheld when the last 50 robotic cases were analysed independently (Two THA list: 133min/THA, Six THA list: 122min/THA).

Conclusions

This study identified a significant improvement in the operating list utilisation when multiple robotic-arm assisted THA cases were listed in
Late Holocene lithic points from a Southern Brazilian mound: The Pororó site
Authors: Moreno de Sousa João Carlos , Garcia Anderson Marques
Published: January 2022

Most lithic industries associated with hunter-gatherergroups in Eastern South America, especially the ones with points present, date tothe Early Holocene, with some minor industries and lithic points typologiespersisting until the Middle Holocene and, more rarely, until the Late Holocene.This is the case for the Garivaldinense lithic industry associated pointstypologies. In this article we present the technological analysis of the pointsidentified at the Pororó site, located in central Rio Grande do Sul State,Brazil. The site is an artificial mound dated to around 2,500 BP. We applied anestablished protocol for analysis of stemmed points considering metric,morphological and technological features that allowed us to classify the artefactsin typologies. We identified two types of points associated to theGarivaldinense lithic industry: the Montenegro and Garivaldinense types. Wehave also identified a new type that has never been described before andproposed to refer to it as the Pororó type. At least one Pay Paso point wasidentified at the site, although this type of point is not yet known at other sitesof this region and chronology. The results indicate persistence of theGarivaldinense Culture from the Early to Late Holocene, as well astechnological innovation during the Late Holocene.
A Caribou Decline Foreshadowed by Inuit in the Central Canadian Arctic: A Retrospective Analysis

Published: January 2022

The Dolphin and Union (DU) caribou herd (Rangifer tarandus groenlandicus x pearyi), locally referred to as Island caribou, is a unique and at-risk ecotype of caribou that ranges on Victoria Island and the adjacent mainland in the central Canadian Arctic. To facilitate the incorporation of traditional knowledge (TK) and better inform the required species recovery plan, we analyzed an archived set of TK interviews done in Ekaluktutiak and Kugluktuk, Nunavut, in 2003. The overarching theme throughout the interviews was that the DU caribou were dynamic, constantly adapting to the changing environment around them. Accounts provided previously unexplored connections between temporal and spatial trends in DU caribou distribution, population, ecology, and disease syndromes. Findings of fewer animals, range shift, and increased observations of disease in the late 1990s and early 2000s suggest that early signs of the declines that have resulted in the herd being reassessed as endangered today were already apparent to Kugluktukmiut in 2003. In contrast, Ekaluktutiakmiut were seeing a stable population. Shifts in caribou range and consequently harvesting ranges were described by both communities, but more evident in Kugluktuk. When combined, the differing accounts of the two communities provided a deeper understanding of caribou ecology and trends across seasons, years, and a broad spatial range. Community differences demonstrate the cruciality of considering unique place-based perspectives and the importance of mobilizing TK from communities and knowledge keepers throughout the caribou range for a herd-level understanding. This study highlights the importance of timely analyses and reporting on TK studies to ensure a nimble conservation response in a rapidly changing environment.
FLEGT Voluntary Partnership Agreement implementation in Ghana: insights from a SWOT analysis
Authors: Adams M.A. , Tegegne Y.T. , Ramcilovik-Suominen S. , Acheampong E. , Attah A.
Published: January 2022

The European Union Forest Law Enforcement, Governance and Trade (FLEGT) Voluntary Partnership Agreements (VPA) is an important international forest governance initiative, yet various implementation challenges remain. The FLEGT VPA implementation challenges are well-documented in the
scientific literature, where various methodologies and research approaches have been used. As the empirical case indicated various contradicting and overlapping claims, where different respondents framed the same situations as strengths as well as weaknesses, and/or as threats as well as opportunities,
we used the strengths, weaknesses, opportunities and threats (SWOT) approach to assess the associated governance changes in FLEGT VPA implementation in Ghana. This paper offers new insights derived from participant observation of the second independent technical evaluation of the Ghana Timber
Legality Assurance System (GhTLAS) conducted in July 2019, and from semi-structured interviews with key informants and a document review. What are considered the greatest perceived strengths – namely multi-stakeholder engagement, clarification of regulatory frameworks, and access to
information – are brought into question once the identified weaknesses and threats are explored in more detail. The identified weaknesses include the top-down nature of the multi-stakeholder process, fatigue related to additional legality principles, and bureaucracy of the GhTLAS, which
negatively affect VPA implementation activities and processes in Ghana.
Excitatory and Inhibitory Neurons of the Spinal Cord Superficial Dorsal Horn Diverge in Their Somatosensory Responses and Plasticityin Vivo
Authors: Sullivan Steve J. , Sdrulla Andrei D.
Published: January 2022

The superficial dorsal horn (SDH) of the spinal cord represents the first site of integration between innocuous and noxious somatosensory stimuli. According to gate control theory, diverse populations of excitatory and inhibitory interneurons within the SDH are activated by distinct sensory afferents, and their interplay determines the net nociceptive output projecting to higher pain centers. Although specific SDH cell types are ill defined, numerous classifications schemes find that excitatory and inhibitory neurons fundamentally differ in their morphology, electrophysiology, neuropeptides, and pain-associated plasticity; yet little is known about how these neurons respond over a range of natural innocuous and noxious stimuli. To address this question, we applied anin vivoimaging approach in male mice where the genetically encoded calcium indicator GCaMP6s was expressed either in vGluT2-positive excitatory or vIAAT-positive inhibitory neurons. We found that inhibitory neurons were markedly more sensitive to innocuous touch than excitatory neurons but still responded dynamically over a wide range of noxious mechanical stimuli. Inhibitory neurons were also less sensitive to thermal stimuli than their excitatory counterparts. In a capsaicin model of acute pain sensitization, the responses of excitatory neurons were significantly potentiated to innocuous and noxious mechanical stimuli, whereas inhibitory neural responses were only depressed to noxious stimuli. Thesein vivofindings show that excitatory and inhibitory SDH neurons diverge considerably in their somatosensory responses and plasticity, as postulated by gate control theory.

SIGNIFICANCE STATEMENTGate control theory posits that opposing spinal excitatory and inhibitory neurons, differently tuned across somatosensory modalities, determine the net nociceptive output to higher pain centers. Little is known about how natural stimuli activate these two neural populations. This study applied anin vivocalcium imaging approach to genetically target these neurons and contrast their responses over a range of innocuous and noxious mechanical and thermal stimuli. Compared with excitatory neurons, we found that inhibitory neurons are more sensitive to innocuous touch and far less sensitive to thermal stimuli. An acute model of pain also revealed that these subtypes undergo divergent mechanosensory plasticity. Our data provide important and novel insights for gate-control inspired models of pain processing.

Objective

Registers of diagnoses and treatments exist in different forms in the European countries and are potential sources to answer important research questions. Prevalence and incidence of thyroid diseases are highly dependent on iodine intake and, thus, iodine deficiency disease prevention programs. We aimed to collect European register data on thyroid outcomes to compare the rates between countries/regions with different iodine status and prevention programs.

Design

Register-based cross-sectional study.

Methods

National register data on thyroid diagnoses and treatments were requested from 23 European countries/regions. The provided data were critically assessed for suitability for comparison between countries/regions. Sex- and age-standardized rates were calculated.

Results

Register data on ≥1 thyroid diagnoses or treatments were available from 22 countries/regions. After critical assessment, data on medication, surgery, and cancer were found suitable for comparison between 9, 10, and 13 countries/regions, respectively. Higher rates of antithyroid medication and thyroid surgery for benign disease and lower rates of thyroid hormone therapy were found for countries with iodine insufficiency before approx. 2001, and no relationship was observed with recent iodine intake or prevention programs.

Conclusions

The collation of register data on thyroid outcomes from European countries is impeded by a high degree of heterogeneity in the availability and quality of data between countries. Nevertheless, a relationship between historic iodine intake and rates of treatments for hyper- and hypothyroid disorders is indicated. This study illustrates both the challenges and the potential for the application of register data of thyroid outcomes across Europe.

Los textos que presentamos en nuestro número 5 se encuentran dentro del espíritu de la revista desde la publicación del primer número: orientarnos por trabajar en la perspectiva de una ciencia social transdisciplinaria. Consideramos que la ciencia social que surgió en Europa en el siglo XIX se construyó sobre principios que permitían una visión racional de la existencia social que permitían la erosión de las imágenes mágicas y míticas de la realidad histórico-social, pero que en la época actual no nos posibilita analizar fructíferamente el mundo en el que vivimos. Ya Aníbal Quijano nos advertía, en una conferencia con la inauguraba el año académico de 1988 de la Facultad de Ciencias Sociales de nuestra Universidad, que los modelos de ciencia social que utilizamos “no permiten producir interrogaciones significativas sobre la realidad y mantienen o reproducen imágenes obsoletas acerca de ella. En breve, el conocimiento que aquellos modelos o paradigmas producen es obsoleto y/o parcial y distorsionado” (Quijano, 1990: 12).
Innovaciones estadísticas y redes neuronales artificiales aplicadas a la prospección geoquímica en los cuadrángulos de Chaparra y Atico, Caravelí – Arequipa
Authors: Bazan Santa Cruz Orlando
Published: January 2022

La prospección geoquímica siempre ha sido y seguirá siendo una de las herramientas más efectivas para la búsqueda de recursos minerales, que se integra con la cartografía geológica base y otras disciplinas como la teledetección y la geofísica. Esta investigación pretende impulsar una nueva metodología de prospección geoquímica combinando el índice de enriquecimiento relativo local (LREI) de elementos indicadores de mineralización (Cu, Au, Ag, Pb, Zn y Mo), coeficientes de rango correlacional (RCC) y el análisis de componentes principales (PCA), a través de superposiciones difusas (fuzzy modelling) y el uso de aprendizaje profundo (deep learning) no supervisado, para generar mapas de prospectividad geoquímica en los cuadrángulos de Chaparra (32o) y Atico (33o) en la provincia de Caravelí, Arequipa. El mapa de prospectividad generado mediante superposición difusa y el mapa autoorganizado (SOM) fueron validados ploteando la ubicación de los depósitos y ocurrencias minerales conocidos, los cuales en la mayoría de los casos se plotean dentro de áreas con alta o moderada prospectividad. Por lo que se concluye que las innovaciones estadísticas univariables, multivariables e innovaciones tecnológicas aplicadas a la cartografía geoquímica son herramientas efectivas para la prospección geoquímica.

Published: January 2022

El modelo geometalúrgico es el resultado de la integración de las disciplinas de geología, minería y metalurgia con la finalidad de agregar valor y disminuiría el riesgo en un proceso como por ejemplo la eficiencia de flotación de calcopirita. El objetivo de este estudio fue calibrar modelos para cuantificar el contenido de arcillas y gangas de un yacimiento hidrotermal del tipo pórfido cobre-oro por espectroscopía NIR. La metodología seleccionada fue diseñar un modelo quimiométrico basado en 173 compositos de taladros diamantinos a los que se le realizó ensayos de difracción de rayos x y espectroscopia de infrarrojo cercano, validándose los resultados con una validación cruzada a través de una metodología machine learning. La creación de los modelos se realizó mediante una regresión no lineal regularizada por el método de Ridge. Se obtuvo modelos con baja linealidad para minerales de calcita y plagioclasa, con valores de R2 (0.51 y 0.78, respectivamente). El modelo de regresión presenta una linealidad para minerales de esmectita, cuarzo, ortoclasa y muscovita mostró un alto R2 (0.95, 0.93, 0.64 y 0.59, respectivamente). Los resultados encontrados para el contenido de arcillas y gangas indican que los análisis de difracción de rayos x se pueden sustituir, en gran parte, por los modelos espectrales. En el caso de la calcita y plagioclasa, sería conveniente realizar una campaña de caracterización, con la finalidad de mejorar el modelo y poder sustituir los análisis de difracción de rayos x para estas especies, lo que permitirá generar un modelo geometalúrgico de una forma rápida y eficiente con un método semi cuantitativo.

El objetivo del presente trabajo fue mostrar la optimización generada por la implementación de la emulsión bombeable en minería subterránea y tunelería; teniendo como base científica los estudios técnicos realizados en las unidades mineras: Condestable, Pallancata, Huarón y Andaychahua. Con la finalidad de obtener: una reducción de costos operativos, mitigación de gases contaminantes y reducción del daño inducido al macizo rocoso; se planteó sustituir nuestra línea base Emulnor por un explosivo que permitiese alcanzar los objetivos anteriormente mencionados, concluyéndose tras diversas pruebas, que la mejor alternativa de optimización la brindaba el Emulfrag, puesto que en comparación a la línea base, nos permitió generar un ahorro de 26.9 USS/m para roca suave, 26.9 USS/m para roca media y 26.9 USS/m para roca dura; en lo que respecta a gases contaminantes se redujo en 55.3 % la emisión de monóxido de carbono y en un promedio de 70.2% de gases nitrosos, se logró la disminución de los gases por combustión de plástico; gracias al efecto deflagrante que produce el Emulfrag a 0.8 g/cm3, se logró que la zona de intenso fracturamiento se redujera en 30 cm y la zona de creación de nuevas fracturas se redujera en 10 cm.

El trabajo de investigación aborda un análisis crítico e interpretativo de dos textos discursivos cinematográficosperuanos: La boca del lobo (1988) del director Francisco Lombardi y La última noticia (2016) del grupo Chaski; y dos discursos teatrales peruanos: Sin Título técnica mixta (2004) del grupo peruano de teatro Yuyachkani y Ruido (2006) de la directora Mariana de Althaus, dichas obras presentadas de nuevo durante el año 2016. Todos estos discursos fueron elaborados para abordar el tema del conflicto armado interno que sucedió en Perú (1980-2000).
Grietas en las fronteras: Insurgencias migrantes en Canadá, solidaridad, refugio, y protección de la vida en los tiempos del covid-19
Authors: Rivas-Sánchez Eloy
Published: January 2022

En el contexto del covid-19, el Estado canadiense ha respondido a la emergencia sanitaria implementando políticas de apoyo para las y los ciudadanos canadienses y aquellas poblaciones que están permitidos de habitar en el territorio canadiense de forma legal. Estas políticas, que excluyen a las poblaciones de migrantes que habitan en el territorio de forma “ilegal”, han tenido como efecto el fortalecimiento y proliferación de las fronteras, externas e internas, que excluyen a las y los migrantes sin estatus y otros migrantes de estatus precario. Frente a esto, las poblaciones de indocumentados y las organizaciones políticas aliadas a estas poblaciones se han movilizado políticamente para brindar protección y refugio de emergencia hacia quienes han sido excluidos en el contexto de la pandemia, así como para demandar estatus legal universal para las y los “sin papeles”. Como resultado de estas luchas, las poblaciones de inmigrantes precarios parecen estar disputando y sometiendo a contradicciones los regímenes dominantes de significación, vigilancia, y delimitación de las fronteras. Sus insurgencias colectivas, es el argumento que se desarrolla en este artículo, parecen estar también reinventando una nueva forma de hacer política que coloca en el centro la protección y prolongación cualitativa de la vida, así como reescribiendo nuevas narrativas sobre el espacio, sobre su pertenencia al territorio canadiense, y sobre el significado que la frontera tiene para ellos. Estas reflexiones se basan en un trabajo etnográfico sobre las movilizaciones de las y los migrantes indocumentados en Montreal, Canadá en el contexto de la emergencia sanitaria generada por el covid-19. El trabajo investigativo ha consistido en el registro de imágenes y narrativas de activistas a través de entrevistas a profundidad, registro de imágenes, y el involucramiento continuo en las luchas sociales de las y los indocumentados en sobre las cuales se reflexiona en este artículo.

The aim of this work is to investigate physical and mechanical performance of fabrics with a conductive fibre after washing conditions. Three commercially available fabrics with a conductive fibre and one fabric without a conductive fibre were chosen as a research object. The physical properties of the fabrics were evaluated by the loss of the mechanical performance, changes in structure and magnetic permeability. Fabric elasticity and thickness decrease after washing, except for the fabric without a conductive fibre. Magnetic field permeability of all fabrics decreases after washing. The properties of the fabric with a conductive fibre woven in one direction change the most, its magnetic field permeability is the greatest. In all cases magnetic field permeability at the seam is lower than in separate pieces of the fabric. The highest frequency of the  fabric with a thread woven in both directions is at the seam but in all cases the frequencies of separate pieces of fabrics are lower. Tests showed that the best dielectric properties are of the fabric with conductive yarn woven in the weft direction and the highest capacitance change of which is ΔC=74,79%.
Interpreting of Live Press Conferences into Lithuanian Sign Language Under Extreme Conditions of the COVID-19 Pandemic
Authors: Stankevič Natalija , Mankauskienė Dalia
Published: January 2022

The article presents a study of the work of Lithuanian Sign Language (LSL) interpreters in the spring of 2020, when live press conferences on the COVID-19 pandemic were interpreted. At the onset of the pandemic, LSL interpreters, like many other national sign language interpreters, were faced with a new form of live interpreting − interpreting under extreme conditions. Over the years the broadcast news interpreting has become routine for LSL interpreters and can be considered as interpreting under normal conditions. During the pandemic, however, LSL interpreters suddenly found themselves having to interpret live press conferences of politicians and experts on the evolving situation of COVID-19, a major challenge. Until then, none of them had ever had to interpret under similar conditions in an environment of tension and uncertainty, and without special training of how to interpret in an emergency. The study was based on the methodology of R. L McKee (2014) for studying the sign language interpreters’ work under extreme conditions during the natural disasters in Australia and New Zealand and distinguished environmental, linguistic, paralinguistic and interpersonal factors, and on in-depth interview with all 9 LGK interpreters who interpreted during live press conferences on the COVID-19 pandemic. It examines how these four factors influenced the work of LSL interpreters.

Effect of Momentum Correlations on the Properties of Fragments Produced in Heavy-Ion Collisions
Authors: Gautam S. , Kant R.
Published: January 2022

We study the effect of momentum correlations on the properties of light and medium mass fragments by imposing the momentum cut in clustering the phase space. The rapidity distributions, dN/ptdpt spectra, and ratio of transverse to longitudinal energy (Erat) for the reactions of 12C+12C and 40Ca+40Ca are analyzed. We have found a significant influence of the momentum cut on these properties of the fragments. The results of our calculations are compared with experimental data.
Роль нерівноважних вакансій у процесі спінодального розпаду
Authors: Тютюнник Н.В. , Гусак А.М.
Published: January 2022

Загальноприйнята модель Кана–Хільярда для спінодального розпаду має принципову ваду, оскільки використовує наближення рівноважнихвакансій, яке справедливе лише для процесів, характерна довжина яких суттєво більша за довжину вільного пробігу вакансій. Запропоновано схему врахування нерівноважного перерозподілу вакансій під час спінодального розпаду і його впливу на кінетику розпаду. На прикладі двовимірної системи проаналізовано ієрархію характерних часів еволюції морфології та концентрації у процесі спінодального розпаду.

Método experimental e ensaios clínicos
Authors: Rosa Claudio D. , Delabrida Zenith
Published: January 2022

O método experimental (ME) envolve um conjunto de procedimentos que podem ser utilizados por várias ciências para responder questões de pesquisa, refutar ou corroborar hipóteses. No presente trabalho, conduzimos uma revisão sistemática de artigos de revisão publicados em português que tiveram como foco explicar o ME. Utilizamos as bases de dados SciELO e Google Acadêmico, sem restringir a data de publicação dos artigos. Incluímos 64 artigos após a aplicação dos critérios de elegibilidade. Por meio da análise de conteúdo, sintetizamos informações desses artigos que favorecem a condução de estudos experimentais e a avaliação crítica de seus métodos. Adicionalmente, apontamos lacunas como a carência de artigos sobre estatística aplicada ao ME e uso de técnicas qualitativas.
«Yo soy Vegeta y cuando jugué con Messi me hice Súper Saiyajin»
Authors: Álvarez Gandolfi Federico , Ariel Del Vigo Gerardo
Published: January 2022

En el presente artículo nos proponemos reflexionar sobre los procesos de construcción identitaria que se despliegan en torno del fanatismo en la Argentina por objetos de la cultura de masas japonesa, conceptualizado en términos de otakismo (Álvarez Gandolfi 2016). Para ello, analizaremos cómo los fans de contenidos como el animé, (auto)identificados como «otakus», dan sentido a las experiencias vinculadas con sus prácticas de consumo, advirtiendo las tensiones en la constitución de las identidades nacionales de estos sujetos atravesadas por contenidos transnacionales, entre significaciones que adjudican a «lo argentino» y a «lo japonés». Ello en un contexto actual de creciente acceso y circulación global de producciones transculturales, de la mano de la digitalización y la consolidación de la cultura participativa en una era interconectada (Jenkins et al. 2016), dentro del cual nos basaremos en investigaciones empíricas propias (Álvarez Gandolfi 2014; Del Vigo y Carpenzano 2014) consistentes en la aplicación de técnicas cualitativas de entrevista con estos fans y en un relevamiento etnográfico de las principales plataformas digitales en las que interactúan. Por un lado, se plantea que las mencionadas tensiones serían resueltas mediante los prosumos otaku que implican una socialización sexoafectiva y un bricolaje identitario sincrético tanto dislocado como potencialmente resistente en el marco del waifuismo (Del Vigo 2018). Por otro lado, se argumenta que para comprender dichas tensiones que atraviesan los procesos de construcción de identidades a partir del otakismo no pueden olvidarse las dinámicas de fragmentación en el interior del fandom ni las maneras asimétricas en que los fans en cuestión las significan en sus narrativas biográficas nostálgicas. Aquí contrastaremos tales planteos y argumentaciones de modo dialógico, desplegando un recorrido conceptual deudor de los estudios culturales y los estudios sobre fans, y de corrientes como el posmodernismo y sus problematizaciones, en pos de consolidar bases posibles para seguir estudiando este fenómeno cada vez más visible e importante en las sociedades contemporáneas.
