F. A. Mann – Výjimečná osobnost a jeho odkaz
Authors: Dannemann Gerhard
Published: April 2024

The subject of this paper is a description and analysis of the life and work of the extraor¬dinary personality of the exiled lawyer F. A. Mann who became an extraordinary expert in public international law, private international law, comparative law and commercial law, who, moreover, laid the foundations of monetary law as a special subject of legal doctrine. As the famous English judge, Lord Denning, would say: “Mann contributed more than anyone else to the development the science of law in our time.” Born in a German Jewish family, he studied and began an academic career in Berlin. He was then forced to flee to Great Britain, where he studied law again and became a renowned solicitor and legal scholar. His career was crowned after World War II, when he became a leading figure in international legal organizations, leaving a far-reaching influence in English and international jurisprudence. In the 1960s and 1970s, he lectured at German universities in particular, where he received the highest honours, and also influenced German jurisprudence.

Published: April 2024

Soybean (Glycine max (L.) Merrill.) is an essential food and industrial crop, but it can be heavily affected by drought, especially during the pod growth stage. Brassinosteroids (BRs) are reported to alleviate drought stress, but the effectiveness may depend strongly on BR concentration and timing of the application, and no research has investigated this issue. This study aimed to determine the suitable concentration of BRs and time of treatment to help soybean plants withstand drought conditions during pod growth. The experiment was conducted with a completely randomized design, with four concentrations of BRs: 0 ppm (water) (B0), 0.1 ppm (B1), 0.2 ppm (B2), 0.3 ppm (B3), and three-time points for the application of BR treatment: soaking before sowing (T1), leaf spray when 50% of plants flowered (T2), leaf spray when 50% of the plants had pod at least 0.5 cm in length (T3). The results showed that when treated with different concentrations and treatment times of BRs, there was no difference in plant growth and development. However, there were differences in the yield of soybean plants. Specifically, treatment B2T2 had the highest total number of firm pods and the highest number of firm seeds at 22.2 and 44.6, respectively, with the weight of 100 seeds reaching 17.9 g, leading to the highest actual yield of 97.0 g/plot. These results indicate that with appropriate concentration and timing (0.2 ppm during flowering), the application of BRs can significantly alleviate drought stress effects on soybean plants during pod growth, improving seed yield and quality.
Shaping of thermal protective properties of basalt fabric-based composites by direct surface modification using magnetron sputtering technique
Authors: Miśkiewicz Pamela , Tokarska Magdalena
Published: April 2024

A direct modification of the surface of the basalt fabric was carried out by using magnetron sputtering to obtain composites intended for effective protection against contact and radiant heat. One-layer composite with a coating of aluminum (Al) and zirconium dioxide (ZrO2), two-layer composite with a coating of Al/ZrO2, and two-layer composite with a coating of Al/(ZrO2 + titanium dioxide [TiO2]) were deposited on the fabric surface. Scanning electron microscopy with energy-dispersive X-ray spectroscopy analysis was used to assess the coating on basalt fabrics and determine their chemical composition. Parameters such as thermal conductivity coefficient, resistance to radiant heat, and resistance to contact heat for a contact temperature of 250°C were determined for assessment of the composites from the point of view of protective properties. The similarity analysis of composites was performed to state the impact of coating components’ content and coating thickness on chosen parameters. It was found that a two-layer composite in which the outer layer is Al and the inner layer is a mixture of ZrO2 and TiO2 provides good thermal insulation properties. The composites capable of protecting against contact heat at the first efficiency level and against radiant heat at the second efficiency level were obtained.
Macroprolactin in mothers and their babies: what is its origin?
Authors: Nishiyama Norito , Hattori Naoki , Aisaka Kohozo , Ishihara Masayuki , Saito Takanori
Published: April 2024

Objectives

Macroprolactinemia is one of the major causes of hyperprolactinemia. The aim of this study was to clarify the origin of macroprolactin (macro-PRL).

Methods

We examined macro-PRL in the sera of 826 pregnant women and in those of their babies’ umbilical cords at delivery. Macro-PRL was evaluated by precipitation with polyethylene glycol (PEG), gel filtration chromatography (GFC), and absorption with protein G (PG).

Results

We detected macro-PRL in 16 out of the 826 pregnant women (1.94 %) and in 14 of their babies, which may indicate the possibility of hereditary origin of macro-PRL. However, the macro-PRL ratios of the babies correlated positively with those of their mothers (r=0.72 for GFC, p<0.001 and r=0.77 for PG, p<0.001), suggesting that the immunoglobulin (Ig)G-type anti-PRL autoantibodies might be actively transferred to babies via the placenta and form macro-PRL by binding to their babies’ PRL or PRL-IgG complexes may possibly pass through the placenta. There were two cases in which only mothers had macro-PRL, indicating that the mothers had autoantibodies that did not pass through the placenta, such as IgA, PRL bound to the other proteins or PRL aggregates. No cases were found in which only the babies had macro-PRL and their mothers did not, suggesting that macro-PRL might not arise by non-hereditary congenital causes.

Conclusions

Macro-PRL in women of reproductive age might be mostly IgG-type anti-PRL autoantibody-bound PRL. The likely origin of macro-PRL in babies is the transplacental transfer of IgG-type anti-PRL autoantibodies or PRL-IgG complexes from the mothers to their babies.
The role of entrenchment and schematisation in the acquisition of rich verbal morphology
Authors: Hržica Gordana , Košutar Sara , Botica Tomislava Bošnjak , Milin Petar
Published: April 2024

Entrenchment and schematisation are the two most important cognitive processes in language acquisition. In this article, the role of the two processes, operationalised by token and type frequency, in the production of overgeneralised verb forms in Croatian preschool children is investigated using a parental questionnaire and computational simulation of language acquisition. The participants of the questionnaire were parents of children aged 3;0–5;11 years (n = 174). The results showed that parents of most children (93 %) reported the parallel use of both adult-like and overgeneralised verb forms, suggesting that Croatian-speaking preschool children have not yet fully acquired the verbal system. The likelihood of overgeneralised forms being reported decreases with the age of the children and verb type frequency. The results of the computational simulation show that patterns with a higher type frequency also show a greater preference for the correct form, while lexical items show both learning and unlearning tendencies during the process.

Authors: Strelcovienė Zita , Machtejevienė Eglė , Minkauskienė Meilė , Traberg Rasa
Published: April 2024

Objectives

Myotonic dystrophy 1 (DM1) is an autosomal dominant inherited neuromuscular disorder. The most severe form is congenital myotonic dystrophy (cDM). Prenatal diagnosis is complicated and sonographic findings of cDM that are not pathognomonic occur in the late second or early third trimester of pregnancy.

Case presentation

It is the case of prenatally diagnosed cDM. In 32 weeks of pregnancy multiple sonographic findings such as severe polyhydramnios, bilateral talipes, fetal legs akinesia, macrocephaly with mild bilateral ventriculomegaly, right-sided pleural effusion and diaphragmatic pathology were observed by fetal medicine specialist. As the patient complained of weakness in her limbs, she was consulted by a neurologist. The neurological examination revealed a pathognomonic sign of DM1 – grip myotonia. The amniotic fluid and the mother’s blood sample were further tested for DM1. This identified >150 repeats in one copy of the DMPK gene of the both, which is consistent with the diagnosis DM1.

Conclusions

The sonographic findings of fetal limb abnormalities with progressive polyhydramnios is an indication for maternal neurological examination and genetic testing due to myotonic dystrophy.
A Comparative Evaluation of Fiscal Stabilization Strategies during the Covid-19 Pandemic with Germany as a Reference Point
Authors: Baudisch Victoria , Neuenkirch Matthias
Published: April 2024

We provide a comparative evaluation of fiscal stabilization strategies during the Covid-19 pandemic. For this purpose, we use Germany’s temporary value-added tax (VAT) rate reduction as a reference point. We construct a credible counterfactual for Germany in a two-step procedure. First, we carry out a careful pre-selection of the donor pool countries to obtain a control group that is highly similar to Germany regarding important post-treatment characteristics. Second, we apply a reweighting scheme on the pre-selected donor countries. The synthetic control group only differs from Germany in the way that it did not implement the temporary VAT rate reduction. Our results indicate that the German VAT cut policy and partial VAT reductions in other countries were relatively ineffective in stimulating consumption with regards to their costs when compared to other measures such as (targeted) direct cash transfers (e.g. implemented in Canada, Denmark, Japan, and the United States). We attribute this to the fact that direct cash transfers are more comprehensible, salient, and actionable, in particular, in a dynamic environment with high uncertainty induced by unclear future economic prospects.

Published: April 2024

This study presents a sustainable method for producing iron oxide nanoparticles (FeO NPs) using aqueous extracts from coffee seeds. Characterization through X-ray diffraction (XRD), scanning electron microscopy, and transmission electron microscopy (TEM) revealed non-spherical NPs ranging from 30 to 50 nm. The XRD analysis confirmed that the face-centred cubic structure and the Debye–Scherrer’s crystalline size support the FeO particle size confirmed from TEM. The synthesized NPs demonstrated significant antimicrobial activity against Escherichia coli and Staphylococcus aureus, as well as antifungal activity against Aspergillus niger. Additionally, they exhibited potent antioxidant properties, effectively inhibiting DPPH, α-amylase, and α-glucosidase compared to acarbose and coffee extract. The findings suggest that these FeO NPs hold promise as antimicrobial, antioxidant, antifungal, and potentially antidiabetic agents.
Residual Compressive Stress to Increase Strength of Welded Constructions Using Mobile Processing Methods
Authors: Baunack D. , Roth J. , Liehr A. , Dürr A. , Niendorf T.
Published: April 2024

Can residual compressive stress, which is etablished using mobile processing methods without the use of specially designed equipment (mobile blasting systems or special hammering equipment), i. e., without noteworthy machine investment, significantly increase the fatigue strength of welded structural steel structures? To answer this question, samples were welded, ground and/or brushed, residual stress states were determined and fatigue tests were carried out. The results obtained show why welded constructions often are characterized by a very different service life. Currently, however, the last operation is not yet used in a standardized, targeted and prescribed manner to ensure a defined and repeatable residual stress state on the surface and thus guarantee a superior fatigue strength of welded assemblies.

Published: April 2024

Carbon polymer nanocomposite is a type of composite material that combines carbon-based materials with polymers and nanoparticles to achieve enhanced properties. These materials are designed to take advantage of the unique properties of each constituent to create a new material with superior performance compared to individual components. Nanocomposites composed of carbon-based polymers are the wonder and novel materials of contemporary research. At the forefront of a more recent scientific revolution, both material science and composite science are involved. Polymer science and nanotechnology are inextricably linked in today’s modern science. The subjects of environmental engineering science and nanotechnology require focused attention since these professions currently offer limited solutions for the increasingly pressing problems of groundwater contaminated with heavy metal and drinking water purification. Carbon polymer composites play a significant role in numerous modern applications due to their excellent electrical, mechanical, chemical, and thermal capabilities. Carbon polymer composites are viewed as desirable candidates for the manufacture of nanocomposite materials due to their nanoscale geometries, high aspect ratio, and specific surface area. Due to the shape-dependent nature of their physical and chemical characteristics as well as their thickness, carbon polymer nanocomposites have demonstrated excellent catalytic activity in organic chemical processes. It has been discovered that the catalytic product from the usage of carbon polymer nanocomposites is of tremendous utility in a variety of sectors, inclusive of material sciences, medicinal, and nutritional for biotechnology. As a result, the demand for carbon nanocomposites has grown quickly and the creation of new preparation techniques elevates a higher level of interaction.

Published: April 2024

The article considers regional issues of the Kazakh transtoposystem. There are a number of problematic issues related to cross-border Kazakh toponymy. The article analyzes only one aspect – the status of binary names in the cross-border toposystem. The goal is to study how obvious the binary opposition is there, considering the etymology of toponyms based on semantic opposition. The toposystem of the Northern and Western regions bordering Russia was used as the empirical material for the study. According to the border administrative-regional division, a number of districts of such regions of the country as North Kazakhstan, Pavlodar, Kostanay, Western Kazakhstan, Aktobe, and Atyrau border with Russia. In the article, a series of binary names along the toponyms of this cross-border zone is formed. In particular, Úlken-Kіshі (Big-Small), Aq-Qara (Black-White), Qara-Sary (Black-Yellow), Jaqsy-Jaman (Good-Bad), Jyly-Sýyq (Warm-Cold), and Ashy-Tushy (Bitter-Fresh) are analyzed. The difference between toponymic binary names and lexical antonyms is considered. We discuss the fact that the contradiction in lexical antonyms is clearly expressed, but in binary opposition along toponyms, the contradiction may not be complete. It is reported that the contradiction of toponyms is recognized only in the toponymic context, and sometimes it is even possible to form a related pair, rather than a semantic contradiction.
Evidence for Two Subpopulations of Cerebrospinal Fluid-Contacting Neurons with Opposite GABAergic Signaling in Adult Mouse Spinal Cord

Published: April 2024

Spinal cerebrospinal fluid-contacting neurons (CSF-cNs) form an evolutionary conserved bipolar cell population localized around the central canal of all vertebrates. CSF-cNs were shown to express molecular markers of neuronal immaturity into adulthood; however, the impact of their incomplete maturation on the chloride (Cl−) homeostasis as well as GABAergic signaling remains unknown. Using adult mice from both sexes, in situ hybridization revealed that a proportion of spinal CSF-cNs (18.3%) express the Na+-K+-Cl−cotransporter 1 (NKCC1) allowing intracellular Cl−accumulation. However, we did not find expression of the K+-Cl−cotransporter 2 (KCC2) responsible for Cl−efflux in any CSF-cNs. The lack of KCC2 expression results in low Cl−extrusion capacity in CSF-cNs under high Cl−load in whole-cell patch clamp. Using cell-attached patch clamp allowing recordings with intact intracellular Cl−concentration, we found that the activation of ionotropic GABAAreceptors (GABAA-Rs) induced both depolarizing and hyperpolarizing responses in CSF-cNs. Moreover, depolarizing GABA responses can drive action potentials as well as intracellular calcium elevations by activating voltage-gated calcium channels. Blocking NKCC1 with bumetanide inhibited the GABA-induced calcium transients in CSF-cNs. Finally, we show that metabotropic GABABreceptors have no hyperpolarizing action on spinal CSF-cNs as their activation with baclofen did not mediate outward K+currents, presumably due to the lack of expression of G-protein–coupled inwardly rectifying potassium (GIRK) channels. Together, these findings outline subpopulations of spinal CSF-cNs expressing inhibitory or excitatory GABAA-R signaling. Excitatory GABA may promote the maturation and integration of young CSF-cNs into the existing spinal circuit.

Drug Screenings in Practice
Authors: O’Neil Meghan M.
Published: April 2024

This research article will contextualize drug testing and conditions of supervision by analyzing eight original in-depth interview and survey narratives provided by persons are in treatment for substance use disorder. We identify a gap in the literature surrounding drug testing as part of community supervision. Specifically, the practice of drug testing from the perspective of the person ordered to test is not well documented. We consider how these experiences diverge from the intention of drug testing by supervising agencies as described in the prior scholarship. This cleavage between the expectations, experiences, and understanding of persons being tested relative to those of supervision agencies presents an avenue for the government to improve community relations, and specifically, improve trust among formerly incarcerated persons towards the supervision process, thereby increasing its legitimacy while enacting procedural justice. The persons under supervision describe broad criminal justice experiences and histories with illicit substances that resulted in drug screenings. The opinions from persons who use drugs towards drug testing and related conditions also vary and suggest evidence-based practices involving drug screening could be helpful to improve compliance with conditions and increase trust towards supervision agencies and courts. Opinions towards obligatory drug screens ranged from fear to one of gratitude. A common theme emerged: when drug tests were viewed as avoidable, respondents described changing their behavior to avoid testing—such as avoiding employers who may test for drug use; when screenings were understood as obligatory, like in the context of court ordered community-based addiction treatment, some respondents identified the broader context of the testing as helpful to their abstinence from drug use. Respondents described drug screenings as impacting their employment, economic well-being, and freedom—in particular, failed drug screens on community supervision, including drug court and other specialized supervision caseloads, could result in punitive action including incarceration and other adverse outcomes like job loss. The risk acknowledgement, however, of consequences of a failed drug screen, had not up to the point of our interview, resulted in long-term abstinence from substances for any of the respondents under community-based supervision.

In the Asia-Pacific region, acute MI (AMI) is associated with a high rate of cardiogenic shock (CS), which increases the risk of mortality several-fold. The management of AMI-CS in the region is heterogeneous and lacks consensus. Hence, an Asian Pacific Society of Cardiology working group developed consensus recommendations on the management of AMI-CS in the Asia-Pacific region. The Asian Pacific Society of Cardiology expert panel reviewed and appraised the available evidence using the Grading of Recommendations Assessment, Development, and Evaluation system. Consensus recommendations were developed and put to an online vote. Consensus was reached when 80% of votes for a given recommendation were ‘agree’ or ‘neutral.’ The resulting statements, which have been endorsed by the Asian Pacific Society of Interventional Cardiology and affirmed by the Society for Cardiovascular Angiography and Interventions, provide guidance on the diagnosis, assessment and treatment of patients with AMI-CS among clinical practitioners in the region.
Spironolactone versus Eplerenone in Patients with Resistant Hypertension: A Systematic Review and Indirect Meta-analysis
Authors: Lim Hanselim , Hamdani Wuri Noviar
Published: April 2024

Background: Spironolactone and eplerenone, both mineralocorticoid receptor antagonists (MRAs), have been shown to be effective in the management of resistant hypertension (RH), although there is a lack of randomised controlled trials (RCTs) that directly comparing the two. This systematic review and indirect meta-analysis compares the two MRAs and their effectiveness in lowering blood pressure (BP) in patients with RH. Methods: RCTs comparing eplerenone or spironolactone with a placebo in RH patients were included in the review. The primary outcome was the mean difference (MD) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). The secondary outcome was the MD of serum potassium levels. The pooled estimates of mean BP and mean potassium level difference were then analysed to attain the adjusted indirect comparisons. Results: Six RCTs involving 665 patients were included in the systematic review. The pooled MD of systolic and diastolic BP between eplerenone and placebo showed a reduction of −0.38 (p=0.0007) and −4.45 (p<0.0001), respectively. The pooled MD of systolic and diastolic BP between spironolactone and placebo showed a reduction of −4.82 (p=0.01) and −2.31 (p=0.006), respectively. The pooled MD of serum potassium levels between eplerenone and placebo as well as spironolactone and placebo was 0.16 (p=0.39) and −0.08 (p=0.59), respectively. An indirect comparison meta-analyses of the MD in systolic and diastolic BP (systolic MD 1.66; 95% CI [−3.46–6.78]; p=0.5250 and diastolic MD 2.14; 95% Cl [−0.63–4.91]; p=0.1293) as well as mean serum potassium levels (MD 0.24; 95% Cl, [−0.23–0.71]; p=0.313) between spironolactone and eplerenone, showed no significant difference. Conclusion: Spironolactone and eplerenone showed an equal reduction in systolic and diastolic BP, as well as serum potassium levels in patients with RH.
Extrañamiento docente respecto a la organización y orientación de los procesos de cambio educativo
Authors: Díaz Torres Juan Manuel
Published: April 2024

El cambio de estructura y procesos de las organizaciones educativas ha generado un gran impacto en la nueva manera de trabajar. Desde este enfoque se estima que la coor­dinación en los centros garantiza que un equipo funcione como un todo unitario, y es identificado como un proceso clave para entender la efectividad de éstos. Se asume así que la coordinación es un proceso que implica el uso de estrategias y de patrones de comportamiento dirigidos a integrar acciones, conocimientos y objetivos de miembros interdependientes. En atención a ello y, desde una revisión de la literatura nacional e internacional actual, este artículo se propone delimitar alguno de los enfoques relevantes sobre mejora educativa y cambio organizativo, mostrando que las tareas han aumentado su dificultad, haciendo que la resolución individual sea muy difícil o imposible. Se conclu­ye que la investigación sobre el cambio educativo, los equipos de trabajo y los procesos de colaboración plantea implicaciones notables para la calidad educativa.
Cultura de trabajo docente y gestión del cambio: del aislamiento a la colaboración
Authors: Corti Ana María
Published: April 2024

El reconocimiento de la necesidad del cambio en las instituciones, centrada en la cultura interna y la mejora, es algo que hoy pocos discuten en el terreno de la gestión escolar —dadas las variaciones culturales, sociales y económicas que presentan las poblaciones demandantes—; sin embargo, llevamos varias décadas de reformas de los sistemas edu­cativos nacionales, centradas en cambios impuestos, que han dejado resultados dudosos en términos de su efectividad, lo que ha ido erosionando la motivación de los actores in­ternos en relación al impacto de estas estrategias para mejorar las condiciones existentes. En este artículo describiremos una experiencia de trabajo en red, fundamentada en la necesidad de mutar hacia formas de trabajo colaborativo con el fin de empoderar a las co­munidades educativas mediante equipos interinstitucionales. La experiencia se caracteriza por la construcción de liderazgos transversales, centrados en la integración, mediante procesos comunicacionales basados en la diversidad y dinamizados por el enriquecimien­to mutuo y el aprendizaje permanente.
Percepción docente de la adaptación escolar del alumnado en riesgo de abandono
Authors: Álvarez Blanco Lucía , Martínez González Raquel Amaya
Published: April 2024

Se exploran algunos de los factores que, desde la perspectiva docente, explican la adaptación escolar del alumnado en situación de fracaso y/o riesgo de abandono prematuro de los estudios. La investigación cuenta con una muestra de 121 profesores/as de Educación Secundaria Obligatoria de Austria Chipre, España y Holanda. Se desarrolla una metodología ex post facto empleando un cuestionario compuesto por siete dimensiones con 34 ítems y análisis estadísticos descriptivos de contingencia y regresión. Los resultados señalan una asociación directa entre la frustración, aburrimiento y desmotivación de estos/as estudiantes con el riesgo de abandono, así como lagunas en el apoyo educativo del entorno, lo que contribuye a que la mayoría del profesorado crea que realmente no les gusta asistir ni permanecer en el instituto. Se sugiere implementar programas de asesoramiento psicoeducativo en materia socioemocional, comunicativa y de enseñanza–aprendizaje que contribuyan a un ejercicio parental positivo, óptima adaptación escolar, progresos en el rendimiento académico, convivencia positiva y, con ello, una reducción de las tasas de abandono escolar.
Adolescencias mexicanas en riesgo: retos para su educación
Authors: Ponce Grima Víctor Manuel
Published: April 2024

Este trabajo aborda la reducción de la capacidad educativa de las adolescencias mexicanas por parte de la escuela pública y sus familias. Muestra cómo muchos adolescentes mexi­canos viven precarios procesos de socialización, sobre todo los más pobres, aquellos que habitan en las periferias urbanas y en las áreas rurales. Se evidencia que la escuela pública y las familias no están dotando a los adolescentes de las capacidades para la adaptación y para la interacción simbólica en sus contextos sociales. Dichos problemas demandan solu­ciones estructurales para ofrecer a las adolescencias en crisis, soluciones sustentables. Fren­te a ello, sostenemos que es otra la educación que tendrá que resolver los efectos perversos de la desigualdad, la inequidad y la exclusión; aquella que haga posible la convivencia. A partir de esta constatación, se propone descubrir a los adolescentes, al mismo tiempo que se sugiere pasar de una escuela ajena a una centrada en las adolescencias.

Derechos del niño, participación infantil y formación ciudadana desde espacios educativos no formales: la experiencia del Consejo Consultivo de Niños, Niñas y Adolescentes de la comuna de Coquimbo, Chile
Authors: Mundaca Rojas Rodrigo , Flores Zúñiga Claudio
Published: April 2024

El año 1990 Chile ratifica la Convención Internacional de Derechos del Niño, lo cual pone en marcha una serie transformaciones sociales e institucionales para ajustar la concepción de niños, niñas y adolescentes como sujetos titulares de derecho. Uno de los elementos más complejos de abordar en este tránsito ha sido reconocer la importancia de la participación infantil como principio rector y como derecho efectivo, lo cual ha llevado a la necesidad de analizar las implicancias concretas de dicho concepto y revisar prácticas que se orienten en esa dirección. El presente trabajo busca aportar en esa discusión, a partir de la sistematización de una experiencia realizada desde la Oficina de Protección de Derechos de la Infancia y Adolescencia de la comuna de Coquimbo, Chile: los Consejos Consultivos de Niños, Niñas y Adolescentes
Slightly Out of Focus. Analysis of Ambiguity in Robert Capa’s Photography
Authors: Susperregui José-Manuel
Published: April 2024

The concept of Slightly Out of Focus, attributed to the photographer Robert Capa, is a line of research that invites us to delve into icons, such as the photographs “The Falling Soldier” and “Crawling through the Water”. Regarding the version presented by proponents of Robert Capa’s work and the results of recent investigations, there are some discrepancies regarding the classification of The Mexican Suitcase II and his photographic style. The conflicts concerning cameras lost negatives, and the effect of blurriness in both icons are coincidences that may form a pattern in the discourse about Robert Capa. This research also analyzes two theses on the biases of press photography and documentary photography. The first thesis considers that in press photography, staging is fraudulent information, but not in documentary photography. The second thesis posits that staging is an unacceptable fraud in both photographic biases. The methodology applied in both theses compares two icons of Robert Capa, considered typical of press photography, with two other icons by photographer Arthur Rothstein, namely, “Cattle Skull” and “Dust Storm”. Rothstein is a reference figure in documentary photography and the 1936 Resettlement Administration program, later known as Farm Security Administration. The press’s reaction to the staging of the photograph Cattle Skull left no doubt about the incompatibility of staging in the context of documentary photography.

The popular Spanish fiction series Money Heist has been seen in more than 190 countries and has won the International Emmy Award for Best Drama. In 41 episodes over five seasons, a group of thieves dressed in red overalls and concealing their faces behind Salvador Dalí masks break into the Royal Mint of Spain and the Bank of Spain with the intention of carrying out an ambitious heist at each location. There are almost no product placements of real-life tourist attractions in the narrative structure of the series. This article discusses whether certain symbolic constructs identified in Money Heist could act as tourism inducers in the same way as the placement of real-life locations, a practice explored extensively in recent research. This study finds a considerable increase in tourist numbers to the Royal Mint of Spain that coincided with a massive rise in searches on YouTube for identifying elements of the series and a significant correlation between those elements and Spanish tourist destinations on Instagram. It thus offers evidence of the presence of symbolic constructs that could serve as inducers of both domestic and international tourism to Madrid.

After the Covid-19 pandemic, political parties and international public institutions consolidated the use of TikTok as a communication tool in order to reach a young audience, which requires dynamic formats and more flexible languages. This study aims to reflect on the characteristics of institutional and political communication research in TikTok, the suitability of its methodologies, conclusions and limitations, and its future prospects. To this end, a systematic review of the scientific literature (SLR) for the period 2018-2023 is carried out, following the standards of the PRISMA Statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). After applying the inclusion and exclusion criteria to 1.186 scientific documents, 21 articles published in the Scopus and Web of Science databases were analysed. The findings indicate that Spain concentrates the highest number of publications, that the phenomenon was not studied until 2021 and that 2022 was the year of highest production. The conclusions suggest that the study of TikTok is in an incipient phase and that content analysis is the predominant methodology, although its samples are small. They also suggest that there is little bidirectionality in communication strategies, that interaction is not related to adaptation to the multimodal language of the platform and that the focus should be on studying the community rather than the messages disseminated from official profiles.
Promoting Hospitals’ Reputation through Smart Branding Initiatives. A Quantitative Analysis of the Best Hospitals in the United States

Published: April 2024

Hospitals use different technological tools to implement corporate communication initiatives and, in this way, improve their relationships with stakeholders (employees, patients, media companies) and build a reputed brand. However, they face different barriers: limited budgets for corporate communication, strict legal frameworks, and stakeholders’ new needs regarding information and emotional support. This paper aims to analyze how the 100 best hospitals in the United States manage smart technologies to promote their brand. To do that, we conducted a literature review about smart hospitals, branding, and corporate communication; and then we defined 34 quantitative indicators to evaluate how the hospitals previously mentioned managed their websites, online newsrooms, about us sections, and artificial intelligence department web sites for reputation purposes. Our results proved that most hospitals respected indicators related to the homepage (8.67/11) but not those referring to online newsrooms (4.44/11) or about us sections (2.66/6). Besides, only 23 hospitals had implemented a department specialized in artificial intelligence that collaborated with external organizations. We concluded that most American hospitals focused their reputation efforts on patients rather than other targets (media companies, employees, suppliers, shareholders); and that these organizations did not integrate enough artificial intelligence projects into their smart branding initiatives.
Transformation and transcendence - reforming news production in the convergent media era
Authors: Li Zhi , Chen Yinchang
Published: April 2024

Abstract: The present-day networked media ecosystem is distinctly characterized by convergence. Recently, media convergence has experienced rapidly progress both in theoretical circles and in practical applications, and convergence development has inevitably become a leading trend in media development. Media convergence has uniquely transformed the ecology of news, communication and public opinion, in which an overhaul of news production stands out as its main expression. As a result of media convergence, news production has shifted from a traditional linear to a nonlinear mode. Due to the use of video, audio and H5 forms of news in new media, in addition to traditional media primarily based on text and image content, news reporting is now more diverse, visually appealing and innovative. The process of producing news has changed as a result of media convergence, becoming more effective, adaptable and diverse. By studying the impact of media integration on news production, this article aimed to understand how media should be adjusted in the era of integration, how news production should develop and break through, and the general laws of news production in the process of integration development. At the same time, in this context, the research under consideration investigates the impact of media convergence on news production, outlines the way that media can adapt to dynamic landscapes, proposes new methods of news production to promote the progress of the convergence era, and aims to establish the basic principles of news production in integrated development. Under the trend of digitization, networking and informatization, the mode of news production has undergone changes. With the rise of new media and the gradual transformation of traditional media, the news production environment and mode have also undergone profound changes. This article revealed the underlying mechanisms and future trends of this change, which can improve the efficiency and quality of news production and enhance its competitiveness in a diversified media environment. It has important reference value for news organizations, media practitioners and relevant policy makers, and can provide scientific basis for their decision-making.
Influência da sala na percepção do som: experimentos em câmara anecoica e câmara reverberante
Authors: Grillo Maria Lúcia Netto , Baptista Luiz Roberto Perez Lisbôa
Published: April 2024

A percepção do som não depende apenas da fonte sonora, há muitas interações das ondas acústicas com o ambiente, de forma que, no caso de instrumentos musicais, a sala funciona como um prolongamento do instrumento. Fatores como geometria, materiais, posição, são determinantes para a percepção do som. A inteligibilidade e o nível de pressão sonora podem variar drasticamente conforme a acústica da sala. Há parâmetros adequados para cada tipo de atividade em uma sala. Uma sala pode ser adequada para determinado tipo de música e para outro tipo não. O tempo de reverberação é um dos parâmetros acústicos a serem observados e, se possível, adaptados para a atividade a ser realizada. Os extremos desse parâmetro, muito alto e muito baixo, estão presentes em uma câmara reverberante e uma câmara anecoica, respectivamente. Fizemos alguns experimentos nesses dois tipos de sala e obtivemos valores muito diferentes do nível de pressão sonora para cada sala, comprovando como a percepção do som varia e evidencia a necessidade de adaptar a sala conforme o tipo de fonte sonora. Se não for possível adaptar a sala, pode-se então variar o tipo de música e a forma de execução, a fim de produzir uma boa percepção sonora.
