Nickel nanoparticles (NiNPs) have been the subject of extensive research over the past decade for a wide range of possible applications due to their exceptional strong catalytic activity, high compressive strength, free radical scavenging, and antibacterial property. In consequence of this, there has been a significant advancement in the methods of producing NiNPs, as well as in the suggested reaction processes and applications of these particles. The production, reaction mechanisms, and practical uses of NiNPs are reviewed in this work. NiNPs with sizes ranging from 1 to 100 nm can be manufactured in a number of different ways for use in both scientific and commercial contexts. Synthesis methods are divided into two categories: top-down methods and bottom-up methods which are subdivided into physical, chemical, and biological strategies. Extensive description has been given for the chemical processes involved in the creation of NiNPs, in particular those involved in biosynthesis approaches. The latest developments in the use of NiNPs in industries such as biomedicine, dye absorption, catalysis, supercapacitors, and dye-sensitized solar cells are reviewed. This work also provides examples of the benefits and functions of NiNPs in catalyzing various processes.
Visibilizando lo invisible: COVID-19 y servidumbre doméstica en América Latina
Authors: Reyes Vasquez G. Larissa
Published: March 2023

La servidumbre doméstica es una forma de explotación humana pluriofensiva que atenta contra la dignidad de las personas. El presente estudio explica cómo influyó la pandemia global COVID-19 en la perpetración y el aumento de situaciones de servidumbre doméstica. Lo anterior se realiza a través de un análisis de factores de riesgo —desigualdad, inseguridad, marginación, pobreza y violencia de género—, presentes a nivel mundial, que facilitan la explotación de mujeres y niñas negras, latinas, migrantes o de escasos recursos económicos. Asimismo, se analiza el estrecho vínculo con la invisibilización de casos y el aumento de la cifra negra de víctimas de esta modalidad de explotación humana. El estudio concluye evidenciando la correlación del aumento de la cifra negra de casos de explotación por servidumbre doméstica con los factores de vulnerabilidad que enfrentan las mujeres en situaciones de crisis como la pandemia global COVID-19.

Published: March 2023

Este texto analiza el acoso sexual en el trabajo (AST) de enfermería a través de la discusión de las relaciones de género, como son el patriarcado y la división sexual del trabajo. El objetivo de la investigación es analizar las configuraciones del acoso sexual en el trabajo de enfermería y su influencia en la salud de enfermeras y enfermeros. La metodología adoptada fue la revisión integral de bibliografía que resultó en una muestra final de 32 artículos seleccionados (Scielo, BVS, Web of Science, Scopus y PubMed). Los resultados apuntan a la ausencia de estudios latinoamericanos, la sobrerrepresentación de aquellos provenientes de países asiáticos y la predominancia de mujeres en la profesión, las cuales sufren más el acoso que los hombres, que también lo sufren. Los problemas de salud desencadenados por el AST son: ansiedad, tensión, depresión, insatisfacción y miedo. Para poner un freno a la violencia contra las mujeres en el trabajo, es necesario contar con pautas de comportamiento construidas colectivamente por las profesionales de salud y hacerlas prioridad en la formación profesional y los movimientos sindicales.

Authors: Kuttner Ádám , Kárpáti Andrea
Published: March 2023

AR/VR applications are gaining prominence in exhibition communication. In this field research project, we developed an assessment model to identify major AV/VR application types and their functions. We then used this model to describe 32 contemporary multimedia exhibition applications in 12 countries. During our visits to the exhibitions, we assumed the perspective of the non-specialist visitor to better identify communicative effects of AR/VR applications and compare them with traditional guides developed for similar exhibitions. Our results show that these innovative sources of information may significantly contribute to visitor enjoyment as well as knowledge gain and retention
BIOLOGIC ACL REPAIR AUGMENTATION
Authors: Lazzaretti Fernandes Tiago , De Castro Fernandes Joao Vitor , Ferreira Barbosa Junior Sergio , Alecrim da Costa Vieira Teófilo Josué , Hernandez Arnaldo José
Published: March 2023

The incidence of anterior cruciate ligament (ACL) injuries is on the rise due to increased physical and sports activities. Thus, ACL reconstruction is a common surgical procedure to treat ACL ruptures, however, it has a failure rate of 0.7–21% and only 63% of the patients are able to recover to their pre-injury sport level. Orthobiologics, including platelet-rich plasma (PRP), growth factors, and stem cells, are being explored as alternative treatment methods to maximize the results and reduce surgical morbidity and healing time. PRP is derived from a blood sample with high platelet concentration and containing growth factors and interleukins. Studies have shown that PRP can improve the maturation of ACL reconstruction but more research is required to support its use in ACL surgery. On one hand, growth factors play a crucial role in ligament healing and PRP, which contains high levels of growth factors, has been shown to stimulate angiogenesis and encourage cell proliferation. On the other hand, stem cells have the ability to differentiate into other cell types and limit the inflammatory microenvironment during acute ligament injury. Ligament-derived stem cells show better potential for lineage-specific tendon/ligament differentiation when used with differentiation inducers. The use of stem cells in ACL reconstruction is still in the early stages of investigation. Therefore, cell therapy agents have shown promising results in preclinical models, but more research is required to determine the most effective biological agents for treatment.

Authors: Wang Ting , Liu Na , Zhou Hui , Chen Mingjun
Published: March 2023

As a key component of lithium-ion batteries (LIBs), separator plays a
crucial role in the performance and safety of LIBs. In this paper, a
cellulose based porous membrane modified by nano CaCO3 is prepared
conveniently by electrospinning. The membrane exhibits rich fibrous
porous networks and uniform distribution of nanoparticles. Strengthed by
CaCO3, the tensile strength of the cellulose porous membrane elevates
from 4.7 ± 0.4 MPa to 7.7 ± 0.7 MPa. Besides, the modified membranes
possess improved thermal stability and can maintain their original size
after treatment at 150 °C and 180 °C. Also, the electrolyte uptake of
cellulose/CaCO3 membrane is 73% higher than that of the pure cellulose
membrane. Thus, the ionic conductivity of membrane achieves 1.08 mS cm-1
and the electrochemical window is about 4.8V, which meets the practical
requirements of LIBs. Significantly, LiFePO4/Li battery this membrane
can run for 230 cycles with a capacity retention of 97.4% and a
discharge capacity of 149.0 mAh g-1, demonstrating the huge potential
for high safety and next-generation LIBs.

Authors: Corey Seth J. , Zobi Mohamed Al , Hurtz Christian , Mehta Hrishikesh , Thomas Stefanie
Published: March 2023

A 19 year-old adolescent girl with Dravet syndrome, characterized by
complex seizure disorder and global developmental delay, presented with
B-cell acute lymphoblastic leukemia. The genetic basis for her Dravet
syndrome was a pathogenic variant in SCN1A, a sodium channel subunit.
SCN1A is chiefly expressed in neuronal tissue, but bioinformatic
analysis demonstrated its presence in B cell lineage. One estimate
suggested that 10% of children with pediatric cancer have a germline
predisposition involving proto-oncogenes or tumor suppressors. This
number might be even higher should non-classical genetic variants, such
as that encoding a sodium channel subunit, be considered.
Quantitative Estimation and Fusion Optimization of Radar Rainfall in Duanzhuang Watershed in the Eastern foot of Taihang Mountains
Authors: Zhang Ting , Li Yi , Li Jianzhu , Li Zhixia , Wang Congmei , Liu Jin
Published: March 2023

Rainfall data, as an important input data, its temporal and spatial
resolution directly affects the accuracy of watershed hydrological
simulations. Weather radar has been used in business in China, but the
uncertainty of radar rainfall data is large, so the two-source rainfall
data fusion based on radar and rainfall stations has become an important
method to obtain rainfall data with high resolution. In this paper,
taking Duanzhuang watershed in the eastern foot of Taihang Mountain for
example, based on the data of 18 rainfall stations in the basin and
Shijiazhuang’s S-band radar data, the radar data are preprocessed,
initially optimized (overall optimization and subsection optimization)
and evaluated. Then 11 rainfalls in this basin are selected by three
fusion methods for fusion and quality evaluation. The results show that
the pre-processed radar rainfall data and the preliminarily optimized
radar rainfall data have poor effects in rainfall spatial estimation
This indicates that single-source radar data cannot be directly used to
describe rainfall events. Among the three fusion algorithms, the
rainfall proportional coefficient fusion method (q_k method) is the
best, the optimal interpolation method is the second, and the mixed
geographically weighted regression-gaussian function (MGWR-GAU) fusion
algorithm is the worst under the conditions of spatial and temporal
variation of rainfall and different station densities. In the case of
q_k method, the correlation coefficients of the three inspection
stations are increased to 0.51, 0.78 and 0.82 on the point scale, and to
0.98 on the basin area scale, and the rainfall changes smoothly in time
and space.It shows this method can effectively improve the data accuracy
of weather radar, and it is an important fusion method to obtain high
temporal and spatial resolution rainfall data in the watershed.

Several biomarkers have been evaluated as predictors of severity or in
directing the treatment of COVID-19, however there are no conclusive
results with prediction of the pathobiology of the infection. In this
study, we evaluated serum levels of cytokines, chemokines, and cell
growth factors in association with the pathobiology of mild to moderate
SARS-CoV-2 infection. Those markers may act as immuno-inflammatory
biomarkers in adults with mild to moderate flu syndrome who sought care
at health units. Serum levels of SARS-CoV-2 infected patients (n=113)
and flu symptoms individuals negative for SARS-CoV-2 (n=58), tested by
the RT-qPCR test - nasal swab were compared to healthy controls (n=53).
Participants who were symptomatic but negative for SARS-CoV-2 were
tested for Influenza A/B and Respiratory Syncytial Virus (RSV). Results
showed that the pro-inflammatory cytokines IL-1β, MCP-3, TNF-α and G-CSF
were increased in symptomatic patients and the cytokines IL-6 and IL-10
were associated with patients positive for SARS-CoV-2 when compared to
healthy controls. Symptoms associated with COVID-19 were fever, anosmia,
ageusia and myalgia. For patients without SARS-CoV-2 infection their
major symptom was sore throat. Five percent (4/83) of SARS-CoV-2
negative patients were positive for RSV. The pathobiology of mild to
moderate SARS-CoV-2 infection was associated with increasing
pro-inflammatory cytokines and also a pleiotropic IL-6 and
anti-inflammatory IL-10 cytokines compared to healthy controls.
Fast Power Density Aware 3D-IC Floorplanning for Hard Macro-Blocks Using Best Operator Combination Genetic Algorithm
Authors: Meitei Naorem Yaipharenba , Baishnab Krishna , Trivedi Gaurav
Published: March 2023

In this article, we propose a fast 3D-IC floorplanning method for hard
macro-blocks that includes a thermal management scheme. It applies a
genetic algorithm constituted by an optimal combination of crossover and
mutation operations to identify the optimal solution for design
variables, namely, total wire length, number of through-silicon vias
(TSVs), and maximum average layer power density. The proposed method
additionally makes use of a unique TSV placement scheme that arranges
TSVs next to their respective functional blocks. To enable efficient
heat transmission to the ambient environment, layers with higher power
densities are placed closer to the heat sink. The proposed 3D-IC
floorplanning approach provides the fewest TSVs, the lowest peak
temperature, and promising values of wire length within the least amount
of computation time. Compared to the recent fast thermal analysis for
fixed-outline 3D-floorplanning, it generates 13.14% shorter wire
length, 39.27% lower peak temperature, and 34.35% lesser number of
TSVs on average with significant improvement in computation time, while
analyzing GSRC thermal benchmark circuits.
A novel protocol for tactile function assessment using extended JVP domes
Authors: Chang Bao-Luen , Wang Yung-Jung , Sung Chung-Tung , Huang Jian-Jia , Pei Yu-Cheng
Published: March 2023

Touch is a crucial sense for perceiving the spatial characteristics of
objects. The JVP dome was developed to evaluate tactile spatial acuity
using a grating orientation task. The application of the traditional JVP
dome to assess tactile function was limited by the ceiling effect,
excessive transition gap between grating widths causing inaccurate
tactile discrimination threshold measurement, and predictive bias due to
the common execution protocol using grating widths in sequence. In this
study, we included additional grating domes and proposed a modified
examining protocol for estimating tactile discrimination thresholds to
improve the accuracy of tactile function assessment. Twelve healthy
participants were enrolled in this experiment. Extended JVP domes with
11 different groove widths were designed. Tactile discrimination
thresholds were estimated using a modified two-down-one-up staircase
method. The experiment comprised practice, training, and testing
sessions, conducted by trained examiners who performed grating
stimulation on participants index fingerpads. All participants passed
the required accuracy in the practice and training sessions. Eight
transition points were obtained in the testing session for each
participant, and tactile discrimination thresholds were all within the
width range of the extended JVP domes. The mean tactile discrimination
threshold was 2.09 ± 0.84 mm. The results demonstrated that the proposed
modified JVP dome set and protocol were successfully applied to assess
tactile discrimination thresholds. The modified protocol with extended
JVP domes provided an effective assessment of tactile function and
improved the precision of threshold measurements, avoided the ceiling
effect found in traditional JVP dome, and eliminated predictive bias.
Balancing EC-Earth3: Improving the performance of EC-Earth CMIP6 configurations by minimizing the coupling cost
Authors: Acosta Mario , Palomas Sergi , Tourigny Etienne
Published: March 2023

Earth System Models (ESMs) are complex systems used in weather and
climate studies generally built from different independent components
responsible for simulating a specific realm (ocean, atmosphere,
biosphere, etc.). To replicate the interactions between these processes,
ESMs typically use coupling libraries that manage the synchronization
and field exchanges between the individual components, which run in
parallel as a Multi-Program, Multiple-Data (MPMD) application.As ESMs get more complex (increase in resolution, number of components,
configurations, etc.), achieving the best performance when running in
HPC platforms has become increasingly challenging and of major concern.
One of the critical bottlenecks is the load-imbalance, where the fastest
components will have to wait for the slower ones. Finding the optimal
number of processing elements (PEs) to assign to each of the multiple
independent constituents to minimize the performance loss due to
synchronizations and maximize the overall parallel efficiency is
impossible without the right performance metrics, methodology and
tools.This paper presents the results of balancing multiple Coupled Model
Intercomparison Project phase 6 (CMIP6) configurations for the EC-Earth3
ESM. We will show that intuitive approaches can lead to suboptimal
resource allocations and propose new setups up to 25% fasters while
reducing the computational cost by 72%.We prove that new methods are needed to deal with the load-balance of
ESMs and hope that our study will serve as a guide to optimize any other
coupled system.
Asymmetry in the Indian Summer Monsoon Rainfall response to two types of La Niña evolution
Authors: Ratna Satyaban B. , Sharma Tanu , Bandgar Arti , Sreejith O. P. , Pai Sivananda , Rajeevan M. , Hosalikar K S , Mohapatra M
Published: March 2023

This study attempts to understand the asymmetry in the Indian Summer
Monsoon Rainfall (ISMR) response to two types of La Niña whether they
evolved from El Niño or La Niña in the previous boreal winter season. It
was seen that nine La Niña years during the monsoon season were preceded
by El Niño (hereafter ELLA) whereas eight were preceded by La Niña
(hereafter LALA) during the period 1961-2021. India received more
rainfall during the ELLA years as compared to the LALA years, linked to
the difference in the Sea Surface Temperature (SST) and large-scale
atmospheric circulation anomalies over the tropical Pacific and Indian
oceans. Based on the strength and patterns of the cold SST anomaly and
shift in the Walker circulation over the equatorial Pacific Ocean, the
enhanced (weakened) convection over the Indian landmass during the ELLA
(LALA) years, contributed to more (less) rainfall over India.
Oceanographic variability in Cumberland Bay, South Georgia, and its implications for glacier retreat
Authors: Zanker Joanna C , Young Emma F. , Holland Paul Richard , Haigh Ivan D , Brickle Paul
Published: March 2023

South Georgia is a heavily glaciated sub-Antarctic island in the
Southern Ocean. Cumberland Bay is the largest fjord on the island, split
into two arms, each with a large marine-terminating glacier at the head.
Although these glaciers have shown markedly different retreat rates over
the past century, the underlying drivers of such differential retreat
are not yet understood. This study uses observations and a new
high-resolution oceanographic model to characterize oceanographic
variability in Cumberland Bay and to explore its influence on glacier
retreat. While observations indicate a strong seasonal cycle in
temperature and salinity, they reveal no clear hydrographic differences
that could explain the differential glacier retreat. Model simulations
suggest the subglacial outflow plume dynamics and fjord circulation are
sensitive to the bathymetry adjacent to the glacier. The addition of a
postulated shallow inner sill in one fjord arm significantly changes the
water properties in the resultant inner basin by blocking the intrusion
of colder, higher salinity waters at depth. This increase in temperature
could accelerate both the subglacial plume-driven melt, and the melting
of the wider submarine ice face, which is proposed as a possible
explanation for the different rates of glacier retreat observed in the
two fjord arms. This study represents the first detailed description of
the oceanographic variability of a sub-Antarctic island fjord,
highlighting the sensitivity of plume dynamics to bathymetry. Notably,
in fjords systems where temperature decreases with depth, the presence
of a shallow sill has the potential to accelerate glacier retreat.
Downcoast Redistribution of Changjiang Diluted Water due to Typhoon Chan-Hom (2015)
Authors: Lin Yunpeng , Li Yunhai , Cong Shuai , Liu Meng , Wang Liang , Zheng Binxin , Xu Jingping
Published: March 2023

Typhoons are known to substantially influence the coastal circulation
and the associated biogeochemical processes. The transport of Changjiang
Diluted Water (CDW), an important source to the coastal current in the
East China Sea (ECS), varies markedly under the influence of typhoons.
This study quantitively details the downcoast transport of CDW driven by
Typhoon Chan-Hom in the summer of 2015. Salinity measurements 3 days
after the typhoon’s passage showed the presence of a large volume of low
salinity water, up to 70 km wide and 20 m thick along the
Zhejiang-Fujian coastal area with an estimated freshwater volume of
3.7×1010 m3. A three-endmember mixing model shows that the CDW’s
contribution to the study area’s surface waters (<10 m)
immediately after the typhoon was as high as 40% (average 32%), much
greater than the contribution under normal summer conditions of 8%
(average 3%). The vast spreading of CDW along the Zhejiang-Fujian coast
created a strong stratification in the upper water column that limited
the diffusion of CDW in the study area. The calculated and observed
results suggest that these abnormal low salinity water could stay in the
study area for 13-21 days. Additional nutrients in the CDW elevated the
Chlorophyll-a concentration in the upper water column (mean 3.74 mg m-3)
and produced large amount of particulate organic carbon (POC).

We present a representation of nitrogen and phosphorus cycling in the
vegetation demography model the Functionally Assembled Terrestrial
Ecosystem Simulator (FATES), within the Energy Exascale Earth System
(E3SM) land model. This representation is modular, and designed to allow
testing of multiple hypothetical approaches for carbon-nutrient coupling
in plants. The model tracks nutrient uptake, losses via turnover from
both live plants and mortality into soil decomposition, and allocation
during tissue growth for a large number of size- and
functional-type-resolved plant cohorts within a
time-since-disturbance-resolved ecosystem. Root uptake is governed by
fine root biomass, and plants vary in their fine root carbon allocation
in order to balance carbon and nutrient limitations to growth. We test
the sensitivity of the model to a wide range of parameter variations and
structural representations, and in the context of observations at Barro
Colorado Island, Panama. A key model prediction is that plants in the
high-light-availability canopy positions allocate more carbon to fine
roots than plants in low-light understory environments, given the widely
different carbon versus nutrient constraints of these two niches within
a given ecosystem. This model provides a basis for exploring
carbon-nutrient coupling with vegetation demography within Earth System
Models (ESMs).

On skew (A,m)-symmetric operators in a Hilbert space
Authors: Rabaoui Rchid
Published: March 2023

In this paper, we study skew (A,m)-symmetric operators in a complex Hilbert
space H. Firstly, by introducing the generalized notion of left invertibility
we show that if T ? B(H) is skew (A,m)-symmetric, then eisT is left
(A,m)-invertible for every s ? R. Moreover, we examine some conditions for
skew (A,m)- symmetric operators to be skew (A,m?1)-symmetric. The
connection between c0-semigroups of (A,m)-isometries and skew
(A,m)-symmetries is also described. Next, we investigate the stability of a
skew (A,m)-symmetric operator under some perturbation by nilpotent operators
commuting with T. In addition, we show that if T is a skew (A,m)-symmetric
operator, then Tn is also skew (A,m)-symmetric for odd n. Finally, we
consider a generalization of skew (A,m)-symmetric operators to the
multivariable setting. We introduce the class of skew (A,m)-symmetric tuples
of operators and characterize the joint approximate point spectrum of such a
family.

Published: March 2023

Soil erosion is a problem that affects the landscape at different scales and represents a serious challenge for land management and soil conservation in both natural forests and meadows. The aim of this study was to determine how the parent material and land use affect the physical and chemical properties of the soil in the area of the Fruska Gora Mountain. The soils were separated into five bedrock types: serpentinite, marl, trachyte, shale, loess and two land use types: forest and meadow. Twenty-three forest soil and 24 meadow soil from a depth of 0?20 cm were sampled from the Fruska Gora Mt. The following properties were determined: pH, electrical conductivity, oxidationreduction potential, content of organic carbon, sodium adsorption ratio, aggregate size and stability. There is no statistically significant difference in pH values, redox potential (Eh), electrical conductivity (EC) and sodium adsorption ratio (SAR) values between the analysed forest and meadow soils, but there is a statistically significant difference in the content of organic carbon (Corg). It can be concluded that both the parent material, and to a slightly less extent, land use have a great influence on physico-chemical properties of the soil.
A Rare Case of Perforated Gastric Remnant after Roux-enY Gastric Bypass

Published: March 2023

Morbid obesity is a major health problem worldwide and the Roux-en-Y gastric bypass (RYGB) is a popular surgical treatment. A 40 year old woman, 17 years post RYGB presented with concurrent symptomatic gastric ulcers and acute pancreatitis. The diagnosis was difficult and after failed medical therapy, surgery was required. The gastric remnant is not easily accessible by endoscopy thus; detecting PUD in this excluded segment is difficult. As a result, alternative methods, such as exploratory laparotomy or pediatric endoscopy may be required to effectively diagnose the gastric remnant.
The Minimalist Program and Optimality Theory: Which is the Most Optimal? Wh-Elements as a Case Study

Published: March 2023

This study analyzes wh-questions from the perspective of the theories of the Minimalist Program and Optimality Theory. We look at specific wh-constructions, including the gap strategy, the in-situ strategy, multiple wh-questions, and relativized wh-questions. This paper shows both the similarities and differences between OT and MP in analyzing wh-elements. One crucial difference is that OT solves the problem of optionality and clearly tackles some aspects of the syntax-pragmatics interface.
La nueva frontera de lo fantástico: escritoras hispanoamericanas en los umbrales de la irrealidad
Authors: Tapia Vázquez Jazmín G.
Published: March 2023

En la actualidad, el auge de la literatura fantástica no puede ser entendido sin la presencia fundamental de escritoras como Mariana Enriquez, Samanta Schweblin, Mónica Ojeda, Liliana Colanzi, Giovanna Rivero, María Fernanda Ampuero, entre otras. Uno de los rasgos en común entre las escritoras que se han dado a la tarea de replantear con nuevos bríos la literatura no mimética o de irrealidad es que muchas de ellas nacieron en los años setenta, décadas convulsas en términos sociales y políticos para Hispanoamérica. Este aspecto resulta muy significativo, pues a pesar de la singularidad de sus escrituras, el tratamiento y renovación que realizan de la literatura de irrealidad se vuelca, principalmente, en la conformación de una crítica sobre la historia social y político de sus países mediada, sobre todo, por el cuerpo, la marginalidad y la violencia. La producción literaria de estas escritoras ha impulsado no solo un cuestionamiento de las teorías clásicas sobre la especificidad de la literatura fantástica y su singularidad respecto a otras modalidades de escritura no mimética, sino también la necesidad de repensar un andamiaje teórico para las literaturas de irrealidad hispanoamericanas. En nuestros días, las obras de estas escritoras responden cabalmente a las exigencias de un replanteamiento teórico sobre la especificidad de lo fantástico, pues hacen de la integración de diferentes discursos de irrealidad una parte nodal de su propuesta generacional y estética, aspecto que las coloca en una nueva frontera de lo fantástico.

Authors: Rantung Kezia C. Y. , Widiasmoro Yohanes M. S. , Dewi Novita
Published: March 2023

This study explores song lyrics to use in language teaching to enhance students’ ecoliteracy while developing their language competency. Today’s language teaching goes beyond language proficiency but capability to address such emerging issues in society as ecological crises. Inclusion of authentic teaching materials like song lyrics may motive learners to be proficient as well as ecoliterate. The method used in this research include data selection, i.e., song lyrics from KePal-SPI, Navicula, and Burgerkill that can be utilized in ELT; data analysis consisting of paraphrasing, speculating, and interpreting of the song lyrics; and evaluating their thematic and linguistic appropriateness for classroom use. The results show that, first, the five song lyrics reveal ecological problems like deforestation and biodiversity loss that the singing artists lament and call for preventive actions. Secondly, song lyrics may offer imaginative use of language that can enable learners to think critically and creatively, hence useful language teaching materials.

FR0089 (reopening). The purpose of a person participating in the auction of Sovereign Debt Instruments is to invest, considering that Government Securities are included in bonds, which is one of the products traded in the capital market as an investment scope. Sovereign Debt Instruments are securities in the form of debt acknowledgments that are guaranteed payment of interest and principal by the Republic of Indonesia according to their validity period, so everything in the object of Government Securities must be accountable by the government, both from the legal aspect and from the economic aspect.

Creación audiovisual colaborativa: enfoques durante la crisis del coronavirus y las restricciones de movilidad
Authors: Balaguer Juanjo
Published: March 2023

Los medios audiovisuales colaborativos se han basado históricamente en el desarrollo de procesos colectivos locales con quienes participan en las iniciativas. En estos procesos, el espacio compartido era fundamental para la consecución de algunos de sus objetivos. Pero con la crisis del coronavirus se han imposibilitado estos encuentros debido al establecimiento de cuarentenas y restricciones de movilidad. La investigación se propone identificar y analizar enfoques que responden a esta limitación en el ámbito de la creación colaborativa durante la pandemia. Para ello, se emplea un método cualitativo basado en el estudio de dos casos de estudio que se definieron en respuesta a la pandemia y se desarrollaron durante las etapas de confinamiento: Nos roban todo, menos la rabia (colectivo LASTESIS, 2020) y Reinventadas (Sonja Marzi, 2021). Con ello, hemos analizado su producción, sus dinámicas de colaboración y su contenido. Aunque el espacio público no podía servir de escenario, ambos casos lo retoman al indagar sobre su alteración con la crisis y las emergencias sociales derivadas de esta transformación. Además, ambos proyectos proponen dos maneras diferentes de construir una obra colaborativa. Con todo ello, la investigación aporta además nuevas perspectivas sobre esta modalidad de producción y su adaptación al espacio virtual.
Justicia social, comunicación y desestigmatización en salud mental. La experiencia de Radio Nikosia
Authors: Correa-Urquiza Martín
Published: March 2023

Nikosia es una radio y una serie de dispositivos comunicacionales en red realizados por personas en tratamiento psiquiátrico. Es una de las primeras emisoras en el territorio español en emitir desde la llamada locura. A partir de un breve análisis de su funcionamiento y articulación como estructura de comunicación y cuidados, la propuesta de este artículo es reflexionar sobre el papel de los medios como altavoces para la palabra de aquellos colectivos históricamente silenciados, y como contextos de posibilidad en las luchas por el cambio y la justicia social en el ámbito de la salud mental. El texto propone entender a Nikosia como un espacio comunicacional de cuestionamiento de la hegemonía psiquiátrica y una instancia de producción de nuevas significaciones en relación con los malestares emocionales y la salud psíquica de las poblaciones. Como un territorio/experiencia que promueve la recuperación del diálogo entre sociedad y locura; un espacio político y comunicacional que habilita en sus participantes la posibilidad de dejar de ser objetos de la intervención psiquiátrica para volver a ser sujetos de sus propios itinerarios vitales. El artículo es resultado de un proceso etnográfico de 5 años de duración, el análisis de 20 programas radiofónicos y la realización de seis entrevistas en profundidad con participantes de la experiencia, y dos grupos focales en donde se debatieron las principales ideas surgidas de las entrevistas.
Witch Trials in Seventeenth-Century Târgu Mureş
Authors: GYÖRGY Árpád Botond
Published: March 2023

The witch trials from Târgu-Mures are typical ones and fit together with the other cases from the early modern period. We can identify the same processes and elements as historiography and ethnography had described. On the other hand, these cases are slightly different because these witch trials were less bloody than usually in the seventeenth century. In the Hungarian Kingdom, the zenith of the witch hunts was in the middle of the eighteenth century. Perhaps the intensity of witch hunts in a medium town was smaller. This paper aims to describe and analyse the witch cases from the seventeenth-century Târgu Mures. These cases are not that remarkable, but we can gain insight into the juridical processes through them.
Rezumat: Procesele de vrăjitorie din Târgu-Mureş sunt tipice şi se potrivesc printre celelalte cazuri din perioada modernă timpurie. Putem identifica aceleaşi procese şi elemente ca cele descrise de istoriografie şi etnografie. Pe de altă parte, aceste cazuri sunt puțin diferite, deoarece aceste procese de vrăjitoare sunt mai puțin sângeroase ca de obicei în secolul al 17-lea. În Regatul Ungariei, zenitul vânătorilor de vrăjitoare a fost la mijlocul secolului al 18-lea. Poate că intensitatea vânătorilor de vrăjitoare într-un oraş mediu a fost mai mică. Studiul de față doreşte să descrie şi să analizeze cazurile de vrăjitorie din secolul al 17-lea din Târgu Mureş. Aceste cazuri nu sunt atât de remarcabile, dar prin ele putem obține o perspectivă asupra proceselor juridice.

What’s the Use of a Manuscript? Uncovering Relevant Information from András Lugosi Fodor’s Unpublished Book
Authors: SZILÁGYI Orsolya
Published: March 2023

András Lugosi Fodor was the medical superintendent of Hunyad (Ro: Hunedoara) County in the first half of the nineteenth century, with a keen interest in Dacian and Roman sites in the region. Some of his most significant contributions to archaeology are a series of unpublished manuscripts. These contain information about his visits to sites, but most importantly, they also present the collections of antiquities belonging to the Transylvanian nobility. Fodor not only provided detailed descriptions about these items, but also drawings. The locations of most of these items are unknown today, making Fodor’s manuscript more important. This paper will try to reconstruct the collection of Roman finds owned by noble families from Hunyad County, based on Fodor’s manuscript.
Rezumat: András Lugosi Fodor a fost superintendentul medical al comitatului Hunedoara (Hunyad) în prima jumătate a secolului al XIX-lea, cu un interes viu pentru siturile dacice şi romane din această regiune. Unele dintre contribuțiile sale semnificative în domeniul arheologiei sunt o serie de manuscrise rămase nepublicate. Acestea conțin informații despre vizitele lui la aceste situri, dar şi mai important, ele prezintă colecțiile de antichități care au aparținut nobilimii transilvănene. Fodor a oferit descrieri detaliate ale acestor obiecte alături de desene ale acestora. Localizarea acestor obiecte este necunoscută azi, făcând ca manuscrisele lui Fodor să fie şi mai importante. Această prezentare va încerca să reconstituie colecția de descoperiri romane aflată în posesiunea unor familii nobile din comitatul Hunedoarei, ba baza manuscriselor lui Fodor.
