Research using GNSS (Global Navigation Satellite System) products – a comprehensive literature review
Authors: Maciejewska Aleksandra , Maciuk Kamil
Published: February 2025

Global Navigation Satellite System (GNSS) products, including satellite orbit and clock corrections, ionospheric and tropospheric delay models, and multi-frequency data, are fundamental to modern geodesy and numerous scientific and industrial applications. The exploitation of these products facilitates the achievement of precise positioning, navigation, and timing (PNT) across a diverse range of fields, including transportation, geodesy, agriculture, and disaster management. Nevertheless, numerous challenges remain, including signal degradation due to multipath effects, atmospheric interference, and vulnerabilities to jamming and spoofing. Recent developments seek to address these limitations and enhance the utility of GNSS products. International collaboration, spearheaded by organizations such as the International GNSS Service (IGS), is crucial for standardizing and distributing GNSS products, facilitating global accessibility and addressing challenges such as climate monitoring and disaster resilience. This review emphasizes the indispensable role of GNSS products in advancing science and industry, highlights persistent challenges, and explores innovative solutions that promise to enhance their accuracy, resilience, and accessibility for addressing global needs.
Charting a Functionalist Business-Centred Approach to Sustainable Development Goal 16.3 Through Business-to-Business Arbitration
Authors: Taiwo Dorcas O.
Published: February 2025

The aim of this article is to establish a link between business-to-business arbitration and sustainable development, and to demonstrate the potential impact of a functionalist business-centred approach to this relationship. While the United Nations Sustainable Development Agenda 2030 acknowledges the importance of civil access to justice for sustainable development, it does not fully define access to justice, thereby leaving open to interpretation what types of alternative dispute resolution mechanisms Agenda 2030 envisages, and which parties should have access to them. Building on Cappelletti and Garth’s work on waves of access to justice, the article proposes a ‘functionalist business-centred approach’ to access to justice. Using legal functionalism, this article argues for a novel interpretation of access to justice in the sustainable development discourse that would expressly include business-to-business arbitration as a civil justice institution on the premise that without business-to-business arbitration, access to justice as a sustainable development goal as expressed in SDG 16.3 cannot be fully actualised.
Academic imperialism meets media imperialism: the case of Abraji in Brazil
Authors: de Albuquerque Afonso , Barba Marcela
Published: February 2025

Purpose

This article examines intellectual and media imperialism as complementary dimensions of cultural imperialism. While previous studies have addressed these concepts separately, this study argues that the United States’ dominant role in the international academic sphere allows it to influence media professionals in other countries, reinforcing media imperialism through a local workforce.

Approach

This article employs a historical-interpretative approach for describing how intellectual imperialism and media imperialism work together. It also incorporates a quantitative analysis of the rise of the disinformation-fighting agenda.

Findings

This study highlights the intricate relationship between external intellectual influence and local media narratives. Based on concrete examples, it shows how the Knight Center influences Brazilian journalists through intellectual training and practical initiatives organized via Abraji.

Practical and social implications

This paper contributes to the broader discourse on cultural dominance and media influence. It emphasizes the need for critical reflection on the role of external forces in national media ecosystems.

Originality/value

The originality of this article lies in its exploration of the intersection between intellectual and media imperialism. It illustrates how external influences, such as the Knight Center, bypass local academic structures and align with US political interests, ultimately affecting national sovereignty and shaping media narratives.
Early life stress impairs VTA coordination of BLA network and behavioral states.
Authors: Stone Bradly T. , Antonoudiou Pantelis , Teboul Eric , Scarpa Garrett , Weiss Grant , Maguire Jamie L.
Published: February 2025

Motivated behaviors, such as social interactions, are governed by the interplay between mesocorticolimbic structures, such as the ventral tegmental area (VTA), basolateral amygdala (BLA), and medial prefrontal cortex (mPFC). Adverse childhood experiences and early life stress (ELS) can impact these networks and behaviors, which is associated with increased risk for psychiatric illnesses. While it is known that the VTA projects to both the BLA and mPFC, the influence of these inputs on local network activity which govern behavioral states – and whether ELS impacts VTA-mediated network communication – remains unknown. Our study demonstrates that VTA inputs influence BLA oscillations and entrainment of mPFC activity in mice, and that ELS weakens the ability of the VTA to coordinate BLA network states, while also impairing dopaminergic signaling between VTA and BLA. Optogenetic stimulation of VTABLAterminals decreased social interaction in ELS mice, which can be recapitulated in control mice by inhibiting VTA-BLA communication. These data suggest that ELS impacts social reward via the VTA-BLA dopamine network.

Significance StatementIt is well established that oscillatory states in the basolateral amygdala (BLA) govern behavioral states. However, a gap in our knowledge exists regarding the mechanisms mediating transitions between BLA network states. Here we demonstrate a novel mechanism modulating BLA network states involving dopamine inputs from the VTA. Further, we demonstrate that early life stress, a major risk factor for psychiatric illnesses, impairs the ability of dopaminergic inputs from the VTA to coordinate BLA and mPFC network states. Thus, this study provides a novel mechanism mediating transitions between oscillatory states in the BLA which are well documented to govern behavioral states and demonstrates pathological perturbations in the ability of the VTA to coordinate BLA network states following early life stress.
Changes to the reproductive microbiome of the brood pouch during male pregnancy in seahorses (Hippocampus abdominalis)
Authors: Wang Jenny , Skalkos Zoe , Grueber Catherine , Whittington Camilla M.
Published: February 2025

Seahorses demonstrate an unusual reproductive strategy in which males incubate embryos inside a complex “brood pouch” until parturition, analogous to mammalian viviparity. In many species, a “normal” reproductive microbiome ensures successful embryogenesis and enables parents (usually mothers) to provide their offspring with their initial microbiome. In male-pregnant seahorses, embryos may receive microbiomes from both parents: from the paternal brood pouch and from the maternal eggs. Using the pot-bellied seahorse (Hippocampus abdominalis), we employed 16S rRNA sequencing to explore the reproductive microbiome. We aimed to compare the microbiome of the male pregnant pouch to the male non-pregnant pouch and external skin, and to identify bacterial taxa found exclusively in the pregnant pouch that could be derived maternally, from the microbiome of eggs. Our findings demonstrate that the pregnant brood pouch microbiome is compositionally distinct from the non-pregnant pouch and external skin. The pouch microbiome also has characteristics of resistance to colonisation by pathogens, including a low species richness, high species evenness and diversity, and very low abundance of Vibrio, a genus that includes fish skin pathogens. Thirteen bacterial taxa appear exclusively in the pregnant pouch, relative to the non-pregnant pouch, and seven of these overlapped with taxa present in or on the eggs. The possible supplementation of brood pouch microbiome with egg-associated micro-organisms hints at a maternal microbial contribution to male pregnancy. This characterisation of the pregnant seahorse pouch microbiome provides a platform for further research into its function and possible adaptive value during male pregnancy.

Authors:   Uniwersytet Warmińsko-Mazurski w Olsztynie, Polska, Lisowska Kinga , Łojko Majka ,   Uniwersytet Warmińsko-Mazurski w Olsztynie, Polska
Published: February 2025

The aim of the article is to analyze the continuity and changes in the cultural identity of Romni in the space of the multigenerational family. The conducted research is a collective case study of 3 families in the grandmother-daughter-granddaughter line. The results of the study indicate that the continuity in shaping the cultural identity of Romni is most strongly influenced by the Romanipen principles, understood as an internal set of rules of coexistence, norms, values, customs, that apply to all members of the Roma community. It is a fundamental determinant in the education of young girls, with the help of which traditional duties and obligations are passed on and the image of Romni is formed. In the multigenerational model of cultural identity, the traditional perception of a woman’s role as mother and wife, responsible for passing on established values to the younger generation, has been observed. The challenges faced by Romni stem not only from the status they occupy within the Roma community, but also from the cultural peculiarities of this minority and traditional perceptions of the position and role of women. Aware of their background and the tasks assigned to them, they generally want to live in accordance with the traditions within their community.
Efficient Ontology-Mediated Query Answering: Extending DL-liteR and Linear ELH
Authors: Dimartino Mirko M. , Wood Peter T. , Cali Andrea , Poulovassilis Alexandra
Published: February 2025

The OWL 2 QL profile of the OWL 2 Web Ontology Language, based on the family of description logics called DL-Lite, is designed so that data stored in a standard relational database system (RDBMS) can be queried through an ontology via a rewriting mechanism, i.e., by rewriting the query into an SQL query that is then answered by the RDBMS system, without any changes to the data. In this paper we propose a language whose expressive power goes beyond that of DL-Lite while still allowing query answering via rewriting of queries into unions of conjunctive two-way regular path queries (UC2RPQs) instead of SQL queries. Our language is an extension of both OWL 2 QL and linear ELH: OWL 2 QL is extended by allowing qualified existential quantification on the left-hand side of concept inclusion axioms, and linear ELH by allowing inverses in role inclusion axioms. We identify a syntactic property of the extended language that guarantees UC2RPQ-rewritability. We propose a novel rewriting technique for conjunctive queries (CQs) under our ontology language that makes use of nondeterministic finite state automata. We show that CQ answering in our setting is NLOGSPACE-complete with respect to data complexity and NP-complete for combined complexity; we also show that answering instance queries is NLOGSPACE-complete for data complexity and in PTIME for combined complexity.
SME internationalisation decision-making: An innovation-based knowledge model
Authors: Linder N. V. , Serezhin P. D.
Published: February 2025

The internationalisation of small and medium-sized enterprises (SMEs) is an important topic in economics, with numerous studies focusing on this process over the past decades. Many researchers have concluded that internationalisation of SMEs is a complex task requiring the consideration of many factors. A key issue in existing research is the insuffi cient attention given to the role of knowledge in the internationalisation process. Despite the recognition of the importance of knowledge, most studies focus on other aspects such as innovation activities, network structures, and management. While these aspects are important, the potential of SMEs remains untapped without adequate attention to the knowledge that underpins successful international operations.

This article proposes a new model of internationalisation based on knowledge-driven innovation, which views international market entry through the lens of knowledge acquired by SMEs and the resulting innovations implemented. The model is based on empirical research with 179 respondents representing SMEs operating in international markets.

The model views internationalisation as a dynamic process in which knowledge-based innovation plays a crucial role at each stage, helping SMEs adapt to international conditions and enhance their competitiveness. The study found that successful internationalisation of SMEs depends on the creation of knowledge-based innovations. Eff ective knowledge management - including collection, storage, dissemination and exploitation - is essential for the development of such innovations. To achieve better results, SMEs should prioritise aspects such as regular knowledge sharing, the use of effi cient information systems, and the involvement of management in knowledge management processes. The knowledge-driven innovation model provides a structured approach to internationalisation, covering the stages of preparation, initiation, and experienced market penetration. 

To successfully enter international markets, it is essential to create an environment where employees understand their role and the importance of knowledge, and where mangement actively supports knowledge sharing and innovation processes. Such approaches will help SMEs achieve sustainable success and remain competitive in international markets.

Authors: Mokshin M. Y. , Putilov A. V. , Rimskaya O. N.
Published: February 2025

Wind energy is a renewable energy source, and wind power is a dynamically developing new branch of non-traditional green energy in Russia and in the world. Despite the sanctions and the unfavourable economic situation in the country, Russian energy specialists are pursuing a course for the wind energy development, supported by government programmes. The difficult situation for the implementation of the green energy programme is linked to objective difficulties: Russia has accumulated a surplus of oil and gas that is not needed in Europe, and Western manufacturers have left the Russian market, without which it is difficult to build new wind turbines. The industry has also accumulated methodological problems - on the choice of a methodology for calculating the efficiency of wind farms and tools for internal and strategic planning. This article is an overview of the amount of energy production from wind farms in Russia and countries around the world.
Małgośka i Damą być, czyli o przekładzie na język niemiecki wybranych tekstów Agnieszki Osieckiej
Authors: Tomecka Magdalena
Published: February 2025

The article discusses translation strategies for the lyrics of Agnieszka Osiecka’s songs, highlighting the challenges associated with transferring verbal-musical content into another language. The article emphasizes that literal translations may not always preserve the original function of the song, and the key decision for the translator becomes the choice between a formal and dynamic approach. The author points out two levels of impact that songs have on the listener: a sensory level, related to sound and melody, and a cognitive level, associated with understanding and interpreting the lyrics. Hence, successful translation of songs requires consideration of both these aspects.

Purpose – This research aims to analyse the impact of extreme cultural tourism based on
individuals’ sentiments, recorded via social media platform (i.e. Twitter presently known
as X). This study explores the thoughts and emotions of twitter users recorded after the
Titan Submersible implosion.
Methodology/Design/Approach – On this front, 6159 tweets (from June 19, 2023, to July 30,
2023) were retrieved and analysed. We employed polarity analysis, emotion analysis, word
cloud analysis and topic modeling.
Findings – Polarity analysis reveals that the inclination of discussion about the Titan
Submersible implosion was predominantly negative. Emotion analysis also shows that most
of the tweets reflect negative emotions and the users’ emotions fluctuate daily. In the word
cloud analysis, the word “missing” appeared in vast majority of the tweets. Topic modeling
reveals the topics that are optimum for this research.
Originality of the research – This study highlights that social media users are sensitive to
manmade disasters particularly associated with extreme cultural tourism. The findings alert the
stakeholders not to compromise on the safety measures and draw the attention of government
authorities to strictly enforce the safety norms to permit extreme cultural tourism in the future.
Determinants of profitability in Indonesian Islamic banks: Financial and macroeconomic insights
Authors: Nisa' Khilyatun , Andriansyah Yuli , Hasan Barham Bakr
Published: February 2025

IntroductionProfitability is a crucial indicator of financial sustainability and competitiveness in the banking industry. For Islamic banks, profitability is influenced by both internal financial management and external macroeconomic factors, shaped by their adherence to Sharia principles. Indonesian Islamic banks operate in a dynamic financial environment that presents unique challenges and opportunities for sustaining profitability.ObjectivesThis study examines the determinants of profitability in Indonesian Islamic banks, focusing on the effects of internal financial ratios—Financing to Deposit Ratio (FDR), Capital Adequacy Ratio (CAR), Non-Performing Financing (NPF), and operating efficiency (BOPO)—as well as external factors such as interest rates and inflation.MethodA quantitative approach was employed, analyzing secondary data from 12 Islamic banks in Indonesia over the 2014–2018 period. Multiple regression analysis was used to evaluate the relationships between these variables and profitability, measured by Return on Assets (ROA). Diagnostic tests ensured the robustness and validity of the statistical model.ResultsThe findings reveal that FDR positively influences profitability, while NPF and BOPO have significant negative effects. CAR and inflation show no significant impact, and interest rates indirectly affect profitability despite the interest-free nature of Islamic banking. These results highlight the interplay of internal management practices and macroeconomic factors in shaping financial performance.ImplicationsThis study emphasizes the need for Islamic banks to enhance credit risk management, optimize operational efficiency, and adapt to macroeconomic conditions to sustain profitability. The findings provide actionable insights for policymakers, regulators, and practitioners aiming to strengthen the financial sustainability of Islamic banking in Indonesia.Originality/NoveltyThis research integrates internal and macroeconomic determinants to offer a comprehensive analysis of profitability in Indonesian Islamic banks. By bridging gaps in the literature, it contributes to the development of strategies for financial performance optimization in Sharia-compliant banking.

Published: February 2025

O surgimento da COVID-19 foi considerado uma emergência de saúde pública de interesse internacional, com alto risco de transmissibilidade que se espalhou por todo mundo, o que a caracterizou como pandemia. Seu impacto incluiu o aumento do adoecimento mental e de traumas psicológicos provocados diretamente pela infecção e/ou por seus desdobramentos secundários. Dessa forma, essa pesquisa objetivou verificar a relação da ansiedade com a COVID-19 para a qualidade do sono e abuso do álcool no estado do Piauí (Brasil) durante o período pandêmico de agosto a setembro de 2022. Contou-se com 303 participantes (Midade = 29; dp = 9,0), os quais responderam a um questionário sociodemográfico online, juntamente com a Coronavirus Anxiety Scale (CAS), o Alcohol Use Disorders Identification Test (AUDIT) e o Pittsburgh Sleep Quality Index (PSQI). Os dados revelaram que a amostra apresentou níveis baixos de ansiedade disfuncional (M = 3,34) e baixo risco para consumo nocivo de álcool (M = 4,13), no entanto, a amostra apresentou má qualidade de sono (M = 7,71). Sendo identificada uma correlação positiva, significativa, moderada entre ansiedade e a COVID-19 e má qualidade do sono (0,30; p < 0,001), este modelo explicou 10% da sua variância (F(1;299) = 37,05, p < 0,001). Conclui-se a necessidade de planejar políticas que conciliem saúde mental e qualidade do sono, capacitando profissionais a lidarem com a situação principalmente em cenários pandêmicos.

Published: February 2025

En el aprendizaje de la aritmética, en los primeros años de la educación formal, interactúan determinados procesos cognitivos, así como variables de tipo sociodemográfico. En este contexto, el objetivo del presente estudio fue analizar la contribución específica de los predictores de dominio específico (comparación simbólica y no simbólica) y de dominio general (memoria de trabajo verbal y visoespacial, alternancia atencional, control inhibitorio e inteligencia fluida) en la resolución de una tarea de aritmética básica en escolares chilenos. Es un estudio correlacional y predictivo, y la muestra estuvo conformada por 203 participantes con desarrollo normotípico, 94 niñas y 109 niños. El modelo de regresión lineal múltiple con pasos sucesivos explicó un 30.4% de la variabilidad en la aritmética básica, y la comparación simbólica fue la variable que tuvo mayor poder predictivo seguida de la alternancia atencional. Estos resultados destacan la implicación de la comparación simbólica y la alternancia atencional en la explicación de la variabilidad en el rendimiento en aritmética básica durante los primeros años de la educación formal, aspecto que destaca la importancia de la evaluación en edades tempranas de múltiples componentes cognitivos que se ha constatado que son predictores de la adquisición del pensamiento matemático, y no sólo centrar las evaluaciones en mediciones basadas en el currículo.
Temporal organization of discursive voices and their association with outcomes in a case of psychotherapy
Authors: Mellado Augusto , Martínez Claudio
Published: February 2025

Voices are the expression of subjective states of patients and therapists in their discourse during psychotherapy. Some voices can be monological, potentially becoming rigid and limiting the experience, and others dialogical, allowing for greater flexibility and reflexivity. The interaction of voices may be disorganized or organized throughout the psychotherapy. A secondary analysis is presented of a case study of a patient diagnosed with Borderline Personality Disorder (BPD). In this 44-session successful psychotherapy (OQ-45.2), different voices were identified using the Discourse Positioning Analysis Model in Psychotherapy (MAPP), and entropy levels (Hs) were assessed in the interaction of these voices using the State Space Grid (SSG) technique. The objective of this study was to describe the temporal association between the interaction of the patient and therapist's reflective voices, their level of organization (entropy), and the patient's outcomes in psychotherapy. To achieve this objective, an idiographic analysis based on vector auto regression (VAR) was conducted. The results suggest a good fit of the model for one-session delays (lag 1). There was temporal stability (autoregression) [p < .01] and a positive trend [p < .00] of the patient's outcomes, and a positive cross-regression between the degree of organization of voices (t-1) and patient outcomes (t) [p < .01]. A temporal dynamic is suggested in which greater organization of patient-therapist voice interactions influences the quality of the patient's outcomes. No significant association could be established between outcomes and reflective voices despite their positive synchronous correlation (lag 0). Studies at the nomothetic level are needed to test an extension of this model.

Published: February 2025

A neurohormone with strong central nervous system activity, melatonin plays a role in
regulating circadian rhythms. It affects practically all tissues and organs and has a broad functional
repertoire. It is primarily employed as a dietary supplement; melatonin aids in sleep regulation and
the re-establishment of arousal cycles. Despite having very low toxicity, melatonin's tissue
availability is constrained by pharmacokinetic problems such as poor oral bioavailability and a brief
half-life. The synthesis and medicinal applications of melatonin and its derivatives are the main
focus of this review study. Melatonin is considered as a beneficial agent suitable for safely treating
and preventing various health conditions. This review covers synthesis approaches and
pharmacological applications of melatonin and its derivatives published from the 1990s to 2024.
The latest development in several studies involves the concurrent administration of melatonin with
other drugs to enhance therapeutic effectiveness and mitigate adverse effects. Hybrid ligands, such
as melatonin-tamoxifen and melatonin-tacrine derivatives are combined to give distinct effects.
This review highlights the importance of continued research into melatonin and its derivatives,
paving the way for developing novel and more potent therapeutic agents.

This research investigates the combined influence of scientific attitude, active learning, and friendly character on the science learning outcomes of junior high school students in Kota Jambi. It explores how these factors contribute to student's academic performance and social development in science education. A mixed-methods approach was used, integrating quantitative data from questionnaires with qualitative insights from interviews. The sample consisted of junior high school students in Kota Jambi. Data analysis was performed using multiple regression tests with SPSS to examine the relationship between the variables. The results indicate that scientific attitude, active learning, and friendly character significantly and positively affect students' science learning outcomes. Active learning enhanced students’ engagement and critical thinking skills, while a strong scientific attitude improved their curiosity and problem-solving abilities. Students with well-developed, friendly character traits also demonstrated better social interactions, leading to more effective collaboration in group-based learning activities. Despite these positive outcomes, the study highlights the challenge of translating scientific concepts into real-world applications, which requires greater emphasis on contextual learning and motivation. This study offers a fresh perspective by integrating social-emotional traits such as friendly character into analyzing science learning outcomes, an area often overlooked in previous research. It provides actionable insights into how fostering active learning and positive social interactions can create a more engaging and effective science learning environment.

Contextualización: el agua es uno de los recursos naturales más importantes para la vida y es el que más está siendo afectado diariamente por las comunidades aledañas a los cuerpos de agua.
Vacío de conocimiento: las autoridades ambientales utilizan muy poco el análisis estadístico multivariado para el estudio de la calidad de agua de las regiones, lo cual es una herramienta importante para la toma de decisiones ambientales.
Propósito: Determinar la variación de la calidad del agua de la Ciénaga de la Virgen mediante el empleo de métodos estadísticos multivariados a datos colectados desde el año 2009 hasta 2017.
Metodología: las muestras fueron tomadas en la ciénaga de la virgen Cartagena de manera mensual, llevadas al laboratorio y analizadas para Amonio (NH4+), Demanda bioquímica de oxígeno (DBO5), Demanda química de oxígeno (DQO), Oxígeno disuelto (OD), pH, Fosforo total (TP), Salinidad, coliformes totales (TC), coliformes fecales (FC), sólidos suspendidos totales (SST). A los datos colectados se le aplicaron análisis multivariados como matriz de correlación, análisis de componentes principales, comparación con diagramas de cajas y bigotes y análisis cluster.
Resultados y Conclusiones: El análisis multivariado de los datos obtenidos evidencian diferentes comportamientos de la calidad del agua en la ciénaga y los factores de contaminación más fuertes es por altos niveles de DBO5 y coliformes totales y fecales. Ambos factores relacionados con aguas residuales y residuos sólidos. La mayor contaminación en la ciénaga es causada por la comunidad y sus residuos sólidos que son arrojados a la ciénaga, es necesario iniciar jornadas de sensibilización de la comunidad cartagenera en temas de cuidado del agua para poder preservar este recurso hídrico tan importante para la ciudad.
On the issue of the multidirectional evolution of the lobbing phenomenon
Authors: Kanevsky P. S.
Published: February 2025

Th is article continues series of publications by the author dedicated to the nature and functions of lobbying in the modern world. Th e author considers lobbying as a multifaceted phenomenon that has gone through a long process of evolution. Th e author suggests looking at lobbying in a historical perspective to show how its genesis was integrated into the logic of the development of the modern state and the market, simultaneously demonstrating why the dysfunctional side of lobbying was always a natural side-eff ect. In the article, the author proposes an innovative periodization of the evolution of lobbying, thus fi lling the gap in Russian political comparative studies in general and in the study of lobbying in particular. Th e author, relying on the logic of Arthur Bentley, shows that lobbying in various forms was inherent in polities and states at diff erent times. However, as the structure of states changed and became more complex, the role of lobbying changed as well. At the same time, the author demonstrates why lobbying remains a largely shadow phenomenon that requires close attention both from the point of view of its further institutionalization and the risks it poses to society and the state. In the conclusions of the article, the author emphasizes that in order to transform lobbying from an informal and illegitimate phenomenon in the public consciousness into a civilized process of interaction between the state and society, the priority should be given to developing a lobbying culture. It is necessary to develop a system of ethical standards for both business and the state, create a professional standard for lobbyists, and continue to improve anti-corruption legislation. But the most important thing is to shift the focus from lobbying based on private interests to lobbying that would refl ect public interests. Only in such way will it be possible to cleanse lobbying of the aura of constant scandals and dishonesty, instead turning it into a normal element of the political process

The rapid development of sound recording and reproduction techniques in the twentieth and twenty-first centuries has contributed to the consolidation of a ‘new sound culture’, characterised by ‘acousmatic listening’ to sounds separated from their original source and context. One of the most interesting examples is the use of classical music in different forms of marketing strategies, such as audiomarketing or sonic branding, to influence consumers’ responses in agreement with the sender’s intentions.

The main aim of this paper is to present selected examples of Polish brands that construct their marketing strategies around Fryderyk Chopin’s works in order to build appropriate brand experience and aura around a product or service in accordance with the rules of sensory marketing. The social enhancement model of music and the hierarchical model of musical semantics are the starting points for understanding the psychological mechanisms that determine the effectiveness of such activities. Overall, the analysis reveals that marketing practitioners focus on two complementary mechanisms (‘directed stimulations’ and ‘directed associations’). Both processes can take part in the transmission of meanings especially on a group level. It leads to some controversies and ethical problems that appear when the boundary between persuasion and manipulation seems to be blurred.

Published: February 2025

Video games is a means of communication with implicit messages that reach millions of users. Mentally ill people are usually represented as violent, out of touch with reality, and often the subject of prejudice. However, there is a branch known as serious games that seeks to raise awareness of mental illness. Our objective is to study how Alzheimer’s is represented in the Spanish video game Inner Ashes (Calathea Studios 2023), and consider the potential of serious games to raise awareness about this mental illness using a ludic-narrative analysis. The results show that narrative factors, such as characters and settings, and video game factors such as mechanics, depict the evolution of this mental condition, and players learn how to react due to the informational component. In conclusion, Inner Ashes is an example of serious games capable of educating about Alzheimer’s by moving away from stereotypes and sensationalism.

In the context of the rapid development of modern society, college students, as the younger generation, no longer merely show traditional respect and care when interacting with the new elderly. The new elderly possess abundant resources in life experience and wisdom, which complement the vitality and innovative characteristics of college students. Through communication and interaction with the new elderly, college students can draw valuable life experience and wisdom from them, helping themselves better adapt to social changes and face challenges. At the same time, college students can provide the new elderly with technical support and professional knowledge, facilitating the elderly’s integration with the times. This bidirectional empowerment relationship is not only conducive to inheriting and promoting traditional filial piety culture but also promotes communication and understanding between different age groups, building a more harmonious and inclusive social atmosphere. Therefore, the interactive relationship between college students and the new elderly is not only an evolution of the concept of filial piety but also a new model of intergenerational communication and joint growth, injecting new vitality and momentum into the development of society.

This article analyzes the primary audience for Dove products: women, and explains how the movement has been given cultural significance, leading to the feminist perspectives presented in the movement. This paper also compares two different views: cultural pessimism and cultural optimism on the commodification of feminism like Dove’s “real beauty” and proposes that commodification of feminism has a positive effect on society.
