Authors: Mehta Kavil , Kumar Prashant , Kushawaha Rajesh K. , Baruah Prahlad K.
Published: December 2024

Hydrogen fuel-based economy has been a prime candidate for sustainable future. Hydrogen generation through water splitting is quite popular, and it has the potential to produce green hydrogen at a very low cost. The development of low-cost, high efficiency electrocatalysts is very important for water splitting processes. Hence, this paper focuses on a novel approach to develop low-cost silver (Ag) nanoparticles doped molybdenum disulfide (MoS2) electrocatalyst for hydrogen evolution reaction (HER). The HER activity of pristine MoS2 nanostructures has also been tested to compare the results with Ag-MoS2 nanocomposites. The materials (MoS2, Ag-MoS2) have been synthesized using pulsed laser ablation in liquid, which is a sustainable technique to synthesize nanomaterials. The developed electrocatalysts have been characterized using various techniques such as scanning electron microscopy, energy dispersive x-ray spectroscopy, UV-Vis spectroscopy, and x-ray diffraction to know their morphology, optical properties, and structural properties. The electrochemical performance study was analyzed in a standard three electrode cell with 0.5M H2SO4. From electrochemical measurement study, it has been observed that Ag-MoS2 has an overpotential of 0.222 V, which is less than that of MoS2 nanosheets (0.274 V). The Tafel slope is also the least for Ag-MoS2 as compared to MoS2. The charge transfer resistance for Ag-MoS2 is 13.05 Ω, while MoS2 provides the resistance of 39.93 Ω. The developed Ag-MoS2 electrocatalyst may be a promising material to generate green hydrogen at the industrial scale.
Gjerningsmannen i den tekstuelle veven. Fra identifikasjon til implikasjon i nyere norsk krigslitteratur
Authors: Jager Benedikt
Published: December 2024

In this chapter, the use of intertextuality in five recent Norwegian novels about the Second World War will be examined. In a first step, possible intertextual traces and their function will be examined in Gaute Heivoll’s Himmelarkivet (2008) and Kjersti Ericsson’s Den hjelpsomme okkupanten (2017). In these novels, the intertextual relationships appear unmarked, while the novels Kraft (2021) by Hanna Dahl, Den siste overlevende er død (2021) by Mattis Øybø and Om stein og jord (2022) by Peter Strassegger choose other strategies: the text of the novel is supplemented by other texts – what Genette calls for paratexts. This is most obvious in the use of extensive bibliographies that contain both fiction and non-fiction. In addition, it turns out that these three novels use several paratextual devices such as mottos, dedications etc. With the help of Paul John Eakin’s thoughts on ‘collaborative autobiographies’ and Michael Rothberg’s theory of ‘the implicated subject’, these paratextual devices will be discussed. It can be shown that the paratextual strategies are an expression of a change in the literary discourse about the Second World War. The text shifts from identification with the victims to implication with the perpetrators.
Frontkjempere. De passive eventyreres fortelling
Authors: Engelstad Audun
Published: December 2024

In spring 2021, the documentary series Frontkjempere (“Front Fighters” – that is, Norwegians who served with the Wehrmacht on the eastern fronts) was screened on the Norwegian public broadcaster channel NRK and immediately caused a heated public debate. The re-enactments were too close to the war film genre, making the front fighters seem like protagonists worth rooting for. Furthermore, the expert witnesses felt betrayed by the production, and wanted to withdraw from the series all together. This chapter will discuss the series in light of how reality, and by extension history, is understood as an integral part of documentary as a film form, while at the same time documentary is given license to enhance narrativization. Documentary representation elicits questions such as ‘Whose story is this?’ and ‘Why is this story being told?’ This again relates to the issue of narrative ethics, and how history is shaped. When perpetrators of war crimes become protagonists, the ethics of historical representation are inevitably brought to the fore.
Tilrettelegging på eksamen for studenter med funksjonsnedsettelser
Authors: Rygg Kari Eldby , Håberg Liv Ingrid Aske , Farstad Beate
Published: December 2024

Retten til tilrettelegging på eksamen for studenter med funksjonsnedsettelser er nedfelt både i universitets- og høyskoleloven (2005) og i likestillings- og diskrimineringsloven (2017). Denne studien undersøker hvordan tilrettelegging på eksamen arter seg i praksis gjennom to tilnærminger. For det første ved å analysere innholdet på nettsider til 32 universiteter og høyskoler om tilrettelegging på eksamen. For det andre ved å gjennomføre kvalitative individuelle intervjuer med 14 studenter med en av funksjonsnedsettelsene dysleksi, ADHD (attention deficit hyperactivity disorder) eller autismespekterforstyrrelse (ASD). Sentrale funn er stor variasjon i informasjon om tilrettelegging på eksamen på institusjonenes nettsider. I tillegg er det mindre samsvar mellom tilgjengelig informasjon og den tilretteleggingen studentene beskriver å ha mottatt. Både på nettsidene og i intervjuene kommer det frem at studenter med dysleksi får tilbud om flere tiltak for tilrettelegging på eksamen enn studenter med ASD eller ADHD. Forholdet mellom rammene lovverket gir og studentenes erfaringer med tilrettelegging blir drøftet i lys av Goodlads læreplanteoretiske elementer (1979). Studien konkluderer med at det er behov for mer kunnskap om tilrettelegging på eksamen for å unngå diskriminering og kunne gi likestilt tilgang til å fullføre høyere utdanning. 
ENGLISH ABSTRACT
Exam Accommodations for Students with Disabilities
The right to accommodation during exams for students with disabilities is enshrined in both the University and College Act (2005) and the Equality and Anti-Discrimination Act (2017). The study investigates how accommodations during exams take place in practice through two approaches. Firstly, by analyzing the content on the websites of 32 universities and university colleges regarding accommodations during exams. Secondly, by conducting qualitative individual interviews with 14 students with one of the disabilities dyslexia, ADHD (Attention Deficit Hyperactivity Disorder), or Autism Spectrum Disorder (ASD). Key findings include a high degree of variation in information about accommodations regarding exams on the institutions’ websites. In addition, there is less correspondence between available information and the accommodations that the students describe as having received. Both the websites and the interviews show that students with dyslexia are offered more measures for accommodations of exams than students with ASD or ADHD. The relationship between the framework provided by the legal system and the students’ experiences with accommodations is discussed considering Goodlad’s curricular theoretical elements (1979). The study concludes that there is a need for more knowledge about examination accommodations to prevent discrimination and ensure equal access to complete higher education.
adolescente em conflito com a lei
Authors: Nantes Samuel , Mariz Inácio Antônio Silva de , Lima Ana Eliza da Rocha
Published: December 2024

O caso dos adolescentes em conflito com a lei é permeado por atravessamentos morais quando notamos a presença do retorno da discussão sobre a maioridade penal e a garantia de direitos humanos. A problemática da pesquisa em questão é levantada a partir do limite entre a constituição do sujeito e a ordem social. A quem está direcionado o ato infracional de um adolescente? Quais são os efeitos de um ato violento na vida dos adolescentes que podem indicar uma reivindicação de constituição e reconhecimento de si diante dos discursos do social por meio de uma modalidade de infração da lei? Do ponto de vista da clínica, a hipótese a ser desenvolvida na pesquisa é que o acometimento de um ato infracional pode ser o meio pelo qual os adolescentes buscam fazer laço com os outros participando das narrativas e discursos em vigor como os infratores e subversivos da ordem corrente.

The article examines the ways of interpreting social processes in the minds of modern people. Analyzing existing interpretations of current events is crucial for developing realistic responses to the challenges of modernity, particularly in the face of global threats. The Enlightenment-era concepts, emphasizing individualistic reason, sensualism, and the rejection of prejudice, play a pivotal role. They formed the core of the currently prevailing liberal ideology. Central to this ideology are conceptions of a naturally correct social structure, collectively constituting the early modern European social project. The main elements of this program are five principles that are closely interconnected. Firstly, this is egoism, inextricably linked with amoralism. Then – rivalry, designated by Kant as “antagonism”. The third principle is laissez-faire, a policy of non-interference in the economy by the state, while the latter is recognized as necessary as a tool for ensuring “rights”. The fourth point is progress, as the confidence that economic growth will create conditions for solving any existing problems in the future. The fifth and most important principle is reliance on the “invisible hand”, which is called upon to guarantee the functioning of the entire system as a whole as a result of omnipotent self-regulation, faith in which is transformed into a quasi-religion.

Educación Superior y cultura digital
Authors: Di Berardino M. Aurelia
Published: December 2024

El objetivo general de este artículo es reflexionar sobre las formas en que el conocimiento se integra en la cultura digital y cuál podría ser la contribución crítica y propositiva de la Enseñanza Superior. Con el fin de alcanzar este objetivo, daremos cuenta, en primer lugar, de una teoría técnica de la información para determinar cómo el proceso de adquisición del conocimiento se desplaza de los individuos a las redes. En segundo lugar, intentaré explicar en qué sentido este proceso promueve una pérdida de experiencia cognitiva.
Si el diagnóstico es plausible, se volverá perentorio pensar acerca de las representaciones de esas nuevas lógicas de adquisición del conocimiento (dominadas por la sobrecarga de información), para establecer puentes entre la Academia y el entorno digital.

Sales strategies with a probabilistic business model of an insurance company: The role of updating and targeting
Authors: Koppány Krisztián , Harmati István Á. , Fülep Dávid , Kovács Norbert
Published: December 2024

The major goal of decisions made by a business organization is to enhance business performance. These days, owners, managers and other stakeholders are seeking for opportunities of modelling and automating decisions by analysing the most recent data with the help of artificial intelligence (AI). This study outlines a simple theoretical model framework using internal and external information on current and potential clients and performing calculations followed by immediate updating of contracting probabilities after each sales attempt. This can help increase sales efficiency, revenues, and profits in an easily programmable way and serve as a basis for focusing on the most promising deals customising personal offers of best-selling products for each potential client. The search for new customers is supported by the continuous and systematic collection and analysis of external and internal statistical data, organising them into a unified database, and using a decision support model based on it. As an illustration, the paper presents a fictitious model setup and simulations for an insurance company considering different regions, age groups and genders of clients when analysing probabilities of contracting, average sales and profits per contract. The elements of the model, however, can be generalised or adjusted to any sector. Results show that dynamic targeting strategies based on model calculations and most current information outperform static or non-targeted actions. The process from data to decision-making to improve business performance and the decision itself can be easily algorithmised. The feedback of the results into the model carries the potential for automated self-learning and self-correction. The proposed framework can serve as a basis for a self-sustaining artificial business intelligence system.

The study aims to examine the labor market challenges and motivational factors for employee retention through the example of a small machinery company in Hungary. In recent years, Hungary’s labor market has faced significant difficulties, particularly due to the COVID-19 pandemic, which resulted in temporary unemployment followed by labor shortages. The research aims to identify the motivational, welfare, and financial factors that contribute to employee retention. Due to the small sample size, we did not investigate the relationships concerning loyalty, commitment, and performance. The research methods included comprehensive data collection at a machinery company employing 24 people located near the Austrian-Hungarian border. During the data collection, we conducted a questionnaire survey that included questions related to benefits, performance, commitment, and loyalty. The collected data were processed by calculating weighted averages and differences. The results indicate that flexible working hours and easy accessibility to the workplace are of utmost importance to employees. There is also a significant demand for performance-based pay and diverse, flexible benefit packages. Employees require both formal and informal professional recognition, such as praise and awards. The research has practical significance for both organizational management and employee well-being. Understanding employee opinions and implementing measures based on these can have four primary effects: improvement in employee performance, reduction in turnover, increase in organizational commitment, and enhancement of the company’s positive perception.

Authors: Lima Jakellyne de , Ambrosio Felipe Augusto Rodrigues
Published: December 2024

O presente estudo aborda a violência contra a mulher no contexto de sua origem histórica, denominação, tipologias e causas. Também buscou destacar as medidas protetivas de urgência e sua ineficácia em relação à aplicação da lei. Examinou-se a violência contra ao gênero feminino em um contexto geral, elencando desde a origem da diferenciação de gênero até os avanços na perspectiva dos direitos inseridos para a proteção da mulher estabelecidos pela Lei 11.340/2006. A Lei nº 14.550/2023 trouxe significativas modificações à Lei Maria da Penha, com destaque para o reforço das medidas protetivas de urgência. Essa nova lei estabeleceu que as medidas protetivas de urgência devem ser concedidas de forma mais célere e efetiva, priorizando a proteção imediata da vítima. A lei também ampliou o conceito de violência doméstica e familiar, incluindo novas formas de agressão, como a violência psicológica e patrimonial e prevê penas mais severas para os agressores e mecanismos mais eficazes para garantir o cumprimento das medidas protetivas, indica medidas específicas para proteger mulheres em situação de vulnerabilidade, como idosas, gestantes, com deficiência e em situação de rua. Além da Lei nº 14.550/2023, outras leis e decisões judiciais têm contribuído para fortalecer a Lei Maria da Penha, como a inclusão da violência psicológica como crime, criação de mecanismos de acompanhamento das vítimas e ampliação da rede de atendimento às vítimas. É fundamental que as alterações na Lei Maria da Penha sejam amplamente divulgadas, especialmente em instituições de ensino, como escolas e universidades. Ao informar sobre os direitos das mulheres e os mecanismos de proteção disponíveis, contribuímos para a prevenção da violência doméstica e familiar e para a construção de uma sociedade mais justa e igualitária. Além disso, a pesquisa bibliográfica indicou as lacunas existentes nas medidas protetivas de urgência e possíveis maneiras de tentar reduzir esse problema.

Published: December 2024

The paper discusses a multilevel voltage source inverter with coupled reactors (MVSI-CR). The output voltage is generated using the novel coarsely quantized pulse amplitude modulation (CQ-PAM). The AC voltage synthesis is realized by selecting and applying an appropriate collection of voltage vectors from the space-vector diagram. Integrating classical two-level inverters allows achieving modularity of the solution. The main advantage of the proposed approach is a very low switching-to-fundamental frequency ratio and a multistep quasisinusoidal output voltage. The paper includes a theoretical analysis, simulations, and laboratory test results.

Published: December 2024

During the product System Test phase, it is necessary to determine the passed/failed status of tests by analyzing network signals. A second layer of verification is introduced by using a camera to take pictures triggered by these signals. An image recognition model is used to identify the successful operation of the product (tests passed), by processing the captured images. The main goal of the proposed method is the improvement of quality assurance techniques. The possibility of automated defect detection in the manufacturing process will lead to improved productivity, higher product quality, and transparency in reporting.
The Potential of Cognitive Artificial Intelligence for Mission-Oriented Military Decision-Making
Authors: Négyesi Imre
Published: December 2024

Artificial Intelligence (AI) and Machine Learning (ML) are rapidly evolving and have already had a significant impact on military capabilities, enabling the deployment of new types of assets and tactics. At the same time, there is a need to explore how AI can help commanders make faster and possibly more accurate decisions. The topic of this publication was the exploration of the potential of cognitive AI for mission-oriented command and control. NATO uses the original, well-established term Mission Command in its doctrines, instead of which the author has used the term mission-oriented command method, which is identical in content to the one used in this article.
Improving Customer Satisfaction in the Immersive Experiences Era
Authors: Porancea-Răulea Andreea
Published: December 2024

For an organization to succeed, it is essential to have customers. In order to evolve and grow, they must become loyal consumers. This approach is challenging in the current era, which is characterized by rapid changes and the increasing use of artificial intelligence. Historically, customers were satisfied with quality alone. However, in the modern context, factors such as globalization, virtual reality, artificial intelligence, and generational differences have made it more difficult for organizations to understand and meet their customers’ needs, and to foster customer loyalty. The objectives of this review paper are twofold: firstly, to collate and examine the existing evidence concerning customer satisfaction, and secondly, to identify strategies and measures that will prove effective in the context of the current era of immersive experiences. The principal conclusion is that the assurance of customer satisfaction is not contingent solely upon the deployment of AI technologies; rather, they exert a considerable influence upon this objective.

Published: December 2024

The development of forms of intercultural communication in modern society necessitates the development of educational technologies that help prepare students for effective intercultural interaction. The article explores the results of pedagogical experiment aimed at development of cultural intelligence of university students by means of World Musics. Since 2007 till 2022th the author has elaborated and implemented her pedagogical system in Moscow State University. For validation of its effectiveness, we used the Expanded Cultural Intelligence Scale in Russian. The sample from 2019 until 2022th consists of students studying at the Faculty of Foreign Languages and Area Studies (161 people), where the control group consisted of 52 people, the experimental group — 109. Comparison of indicators in the experimental and control groups before the application of the author’s system did not reveal any differences (Mann-Whitney U test, p > 0.05). Comparison of indicators in the control group after training Mann-Whitney U test, p < 0.05) did not reveal significant changes, with the exception of the cognitive component (Wilcoxon, p < 0.05). Comparison of indicators in the experimental group before and after the application of the author’s system revealed significant differences (Wilcoxon test, p<0.05). Within the experimental group, the indicators differ significantly depending on the type of discipline (compulsory or optional). The predictor “course delivery format” (face-to-face, online or hybrid) did not show significant changes. The introduction of an academic discipline aimed at studying traditional music of different nations into the elective part of the main professional educational programs of higher education can contribute to the development of students’ cultural intelligence.
