    Full text link
    This study deals with secondary school students’ L2 learning motivation and anxiety. For the investigation of this interrelation, quantitative methods were used: students (n=1019) from five different secondary schools were surveyed. The aim of this research was to explore how individual learner differences influence L2 learning in different educational settings in Hungary, including metropolitan and elite secondary schools, vocational schools, church-run secondary schools and secondary schools in the countryside. Our results show that there are differences among the motivation levels and anxiety levels of students from different types of schools. The results also suggest that learners’ immediate learning environments have a significant impact on their attitudes towards L2 learning. This study can serve as input for the further development of teaching strategies at the institutional level: results can help different types of schools to find ways to support and aid their students’ language learning in a more effective way. The results could also serve as a starting point for further research aimed at deepening the understanding of L2 learning processes and improving L2 teaching practices.Jelen tanulmány középiskolás diákok idegennyelv-tanulási motivációjával és szorongásával foglalkozik. A kutatáshoz kvantitatív módszereket alkalmaztunk: a vizsgálat során öt különböző középiskola diákjainak (n = 1019) adatait elemeztük és hasonlítottuk össze. Kutatási célunk az volt, hogy feltárjuk, ezek a tényezők különböző oktatási környezetekben – beleértve ebbe fővárosi elitgimnáziumokat, szakgimnáziumokat, egyházi fenntartású középiskolákat, valamint a nem fővárosi középiskolákat – miként befolyásolják a nyelvtanulási folyamatot. Eredményeink azt mutatják, hogy kimutatható különbségek vannak az egyes iskolatípusok diákjainak motivációs szintjei és szorongásuk mértéke között. Az eredmények alapján azt is megállapítottuk, hogy a tanulási környezet jelentős mértékben befolyásolja a diákok nyelvtanulási hozzáállását. A tanulmány útmutatást nyújthat a helyi szintű oktatási stratégiák továbbfejlesztéséhez: azaz abban segíthet, hogy a különböző típusú iskolák megtalálják annak a módját, hogy még hatékonyabban tudják támogatni tanulóik nyelvtanulását. Az eredmények mindemellett alkalmasak lehetnek további olyan kutatások kiindulópontjának is, amelyek célja a nyelvtanulási folyamatok mélyebb megértése és a nyelvoktatásban alkalmazott gyakorlatok továbbfejlesztése

    The new procedures and complex methodologies that have emerged today can be used in a variety of social and natural science fields. One of these is the Qualitative Comparative Analysis (QCA), which is suitable for explaining complex social phenomena and situations, and which uses a logical, set-theoretic approach to explore and analyse causal relationships. The paper seeks to answer the question of whether or not qualitative comparative analysis can be classified within the quantitative, qualitative or mixed paradigms, and then outlines aspects of the methodology from a qualitative perspective. It analyses the status of equifinality, sample size, null cases and the role of the researcher in studies using qualitative comparative analysis.A napjainkra létrejött új eljárások és összetett módszertanok a különböző társadalom- és természettudományi területeken egyaránt használhatók. Ilyen a kvalitatív összehasonlító elemzés (QCA) is, amely összetett társadalmi jelenségek, szituációk magyarázatára alkalmas, az ok-okozati összefüggések feltárását és elemzését logikai, halmazelméleti úton valósítja meg. A tanulmány arra a kérdésre keres választ, hogy a kvalitatív összehasonlító elemzés besorolható vagy sem a kvantitatív, a kvalitatív vagy a kevert paradigma keretei közé, majd a módszertant kvalitatív aspektusból megvilágító szempontokat vázol. Elemzi az ekvifinalitás (többszörös konjunkciós okozás), a mintaelemszám, a nulla kimenettel rendelkező esetek és a kutatói szerep helyzetét a kvalitatív összehasonlító elemzést alkalmazó vizsgálatokban

    The increasing penetration of photovoltaic (PV) systems and the need for reliable backup power solutions have led to the development of hybrid uninterruptible power supply (UPS) systems. These systems integrate PV energy storage with battery backup and grid power to optimize real-time energy management. This paper proposes an advanced energy management strategy and an artificial neural network (ANN) based control method for PV-integrated hybrid UPS systems. The proposed strategy dynamically determines the optimal power-sharing ratio between battery storage and the grid based on real-time economic parameters, load demand, and battery state of charge (SoC). A centralized ANN-based controller ensures precise control of the LLC converter and rectifier, achieving stable and efficient power distribution. Additionally, a genetic algorithm is implemented to optimize the power sharing ratio, minimizing the LCOE under varying load and electricity pricing conditions. The proposed approach is validated through simulations, demonstrating significant improvements in cost-effectiveness, system stability, and dynamic adaptability compared to conventional control methods. These findings suggest that integrating ANN-based control with optimized energy management can enhance the efficiency and sustainability of hybrid UPS systems, particularly in fluctuating energy markets. With the application of ANN-based control, the power sharing error was reduced to less than 1%, while the intermediate loop voltage deviation was less than 2 V under dynamic conditions.A fotovoltaikus (PV) rendszerek növekvő penetrációja és a megbízható szünetmentes megoldások iránti igény a hibrid szünetmentes áramellátó rendszerek (UPS) kifejlesztéséhez vezetett. Ezek a rendszerek a valós idejű energiagazdálkodás optimalizálása érdekében integrálják a PV energiatárolást az akkumulátoros tartalék- és hálózati energiával. Ez a tanulmány egy mesterséges neurális hálózaton (ANN) alapuló szabályozási módszert javasol a PV-integrált hibrid UPS-rendszerekhez. A javasolt stratégia dinamikusan határozza meg az optimális teljesítménymegosztási arányt az akkumulátortároló és a hálózat között a valós idejű gazdasági paraméterek, a terhelési igény és az akkumulátor töltöttségi állapota (SoC) alapján. Egy központosított ANN-alapú szabályozó biztosítja az LLC konverter és az egyenirányító pontos szabályozását, stabil és hatékony teljesítményelosztást elérve. A javasolt megközelítés szimulációkkal kerülnek validálásra, és a hagyományos szabályozási módszerekhez képest jelentős javulást mutatnak a költséghatékonyság, a rendszer stabilitása és a dinamikus alkalmazkodóképesség terén. Ezek az eredmények azt mutatják, hogy az ANN-alapú szabályozás integrálása növelheti a hibrid UPS-rendszerek hatékonyságát és fenntarthatóságát. Az ANN-alapú szabályozás alkalmazásával a teljesítménymegosztás hibája 1% alá csökkent, míg a közbenső kör feszültségének eltérése legfeljebb mintegy 2 V volt dinamikus körülmények között

    Full text link
    In recent years, leaders of small and medium-sized enterprises (SMEs) have been facing increasingly complex challenges driven by generational shifts in the labour market and the rapid advancement of digitalization. Employees from Generations Y and Z are becoming more prominent in the workforce, and their expectations and digital skills differ significantly from those of previous generations, posing new challenges for employers. These younger generations place a high value on flexibility, quick access to technological tools, opportunities for professional development, and a value-driven corporate culture. The aim of this research is to illustrate how leaders can respond to these emerging challenges, using a Hungarian SME operating in the IT sector as a case study. Developing leadership strategies that adapt flexibly to these challenges is essential for SMEs to maintain their competitiveness and retain talent. Digitalization further intensifies leadership challenges, as it not only enhances business processes but also fundamentally reshapes workplace environments and communication. Supporting remote work and integrating digital tools require new leadership competencies. The examined SME has implemented a digital onboarding (supporting integration) system that accelerates integration and uses online performance tracking platforms to improve the quality and frequency of feedback. Aligning generational work styles and motivations, as well as leveraging digital opportunities effectively, are key to success. The research is based on a literature review and a case study. Findings indicate that the adoption of digital solutions, intergenerational collaboration, and value-based leadership practices are essential for the long-term success of SMEs. The results offer practical guidance for SME leaders, helping them adapt effectively to continuously evolving external challenges.A kis- és középvállalkozások (KKV-k) vezetői az utóbbi években egyre összetettebb kihívásokkal néznek szembe, amelyeket a generációs munkaerőpiaci átalakulás és a digitalizáció gyors ütemű fejlődése idéz elő. Az Y és Z generáció munkavállalói egyre nagyobb arányban jelennek meg a munkaerőpiacon, ugyanakkor elvárásaik és digitális készségeik jelentősen eltérnek az előző generációkétól, ami új kihívások elé állítja a munkáltatókat. Számukra kiemelten fontos a rugalmasság, a technológiai eszközökhöz való gyors hozzáférés, a szakmai fejlődési lehetőségek, valamint az értékalapú vállalati kultúra. A kutatás célja, hogy egy magyar informatikai szektorban működő KKV példáján keresztül bemutassuk, hogyan reagálhatnak a vezetők a felmerülő kihívásokra. A kihívásokhoz rugalmasan igazodó vezetési stratégiák kialakítása nélkülözhetetlen a KKV-k számára ahhoz, hogy biztosítsák versenyképességüket és megtartsák a tehetségeket. A digitalizáció tovább fokozza a vezetői kihívásokat, mivel nemcsak hatékonyabbá teszi az üzleti folyamatokat, hanem alapjaiban formálja a munkahelyi környezetet és kommunikációt. A távmunka támogatása és a digitális eszközök integrálása új vezetői kompetenciákat kíván. A vizsgált KKV digitalizált onboarding (beilleszkedést és szocializációt támogató) rendszert vezetett be, amely gyorsítja a beilleszkedést, míg az online elérhető teljesítménykövető platformok javítják a visszajelzések minőségét és gyakoriságát. A generációs munkastílusok és motivációk összehangolása, valamint a digitalizáció lehetőségeinek hatékony kihasználása kulcsfontosságú. A kutatás szakirodalmi elemzésre és esettanulmányra épül. Az eredmények alapján a digitális megoldások bevezetése, az intergenerációs együttműködés és az értékalapú vezetési gyakorlatok elengedhetetlenek a KKV-k hosszú távú sikeréhez. A kutatás eredményei gyakorlati iránymutatást nyújtanak a KKV-k vezetői számára, segítve őket abban, hogy sikeresen alkalmazkodjanak a folyamatosan változó környezeti kihívásokhoz

    The Dynamism of Expertise: The Qualitative Content Analysis of the Articles of a Software Engineer Turned into Freelance Author

    No full text
    My paper studies the relationship of two different professional positions in the oeuvre of David Auerbach, an American software engineer who quitted his job at Google and became a cultural critic and freelance author. I am interested in the dynamism of Auerbach’s career: though he–inspired by his literary and cultural affections–left his firstly chosen programmer vocation and became a freelance author, he, as a writer, turned back to the questions of computer science, besides the topics of humanities, and occasionally connected the two areas together. My qualitative content analysis, through two concrete examples, demonstrates how the different areas of interest mingle, confront and influence each other in Auerbach’s articles

    As a result of the experience of the Great War (1914–1918), the disarmament, firstly conceptualized in the Fourteen Points of American President Thomas Woodrow Wilson, has become a crucial problem of international affairs in the Interwar Period. Italy’s attitude toward it was ambivalent: on one hand, Italy wanted to demonstrate its promptness of cooperation with France, United Kingdom and United States of America, but on the other hand, the National Fascist Party’s hegemonic ambitions did not match with the conception of disarmament. The London Naval Conference (1930) can be considered as the culmination of the conflict on the question of the maximum size of the naval forces between Italy and France, as French politicians urged the changing of the parity declared by the Washington Naval Treaty (1922). The question of Italian–French parity was negotiated at the Geneva Disarmament Conference (1932) as well, but the parties could not find any solution. In London and in Geneva Dino Grandi, Italian Minister of Foreign Affairs, represented Italy and did his best to find a compromise in the question, but his efforts caused some disagreements with Benito Mussolini, Head of Government, showing the contradictions of the Fascist policy.As a result of the experience of the Great War (1914–1918), the disarmament, firstly conceptualized in the Fourteen Points of American President Thomas Woodrow Wilson, has become a crucial problem of international affairs in the Interwar Period.

    In recent years environmental issues gained significant interest that has led to an increased awareness of environmentally friendly products. However, trust plays a crucial role, how consumers approach to and adopt these products. Trust serves as the core upon which consumer acceptance of environmentally friendly products is built. Consumers are more likely to choose these products when they feel that they are behaving eco-friendly and sustainable. Trust is multifaceted and can be influenced by various factors, including the credibility of product claims, brand reputation, and transparency in manufacturing processes.One of the most crucial factors influencing trust in environmentally friendly products is the credibility of their environmental claims. Consumers are increasingly analysing product labels and certifications to ascertain their authenticity. Companies that provide clear and transparent information about their products’ environmental attributes foster trust among consumers. Moreover, third-party certifications from reputable organizations serve as a signal of credibility, reassuring consumers of the product’s environmental authorization.This paper gives an overview about the importance of trust in consumers’ acceptance of environmentally friendly products. In-depth interviews were carried out for the deeper analysis to highlight the drivers and disincentives of trust in green products. The possible reasons behind the still moderate level of trust in environmentally friendly products are analyzed and suggestions are formulated how these information barriers could be overcome or eventually be eliminated completely. It is important in the future as trust plays a fundamental role in consumer acceptance of environmentally friendly products. Credibility, brand reputation, and transparency are essential factors shaping consumer trust in these products. As consumer awareness of environmental issues continues to rise, companies must prioritize building and maintaining trust to succeed in the growing market for environmentally friendly products.In recent years environmental issues gained significant interest that has led to an increased awareness of environmentally friendly products.

    Miért volt Churchill Párizsban 1919-ben?

    Full text link
    Churchill was not an official member of the British peace delegation in Paris, but he took part in the negotiations on several occasions as head of the Ministry of War Material Supply and later the Ministry of War and Air. In the Cabinet, Lloyd George’s views differed from Churchill’s, who had sought to support the Whites against the Bolsheviks in the Russian Civil War. The British had serious commercial and geopolitical interests in this, and therefore maintained contacts with the Tsarist military commanders, particularly with Denikin. Military missions were sent to Russia, military missions were set up, and substantial financial support was given to the anti-Bolshevik forces. International support could not be obtained in the Supreme Soviet on 15 February 1919, and the parties took opposing positions on the solution. In the end, the Prinkipo conference never materialised. The implementation of Blackwood’s directives, and then Holman’s military mission, became impossible because of the Bolshevik successes. The trade agreement with the British on 22 March 1921 was a recognition of Soviet power. Churchill’s secret war ended, and the nature of international intervention faded from the literature. The intervention itself was unsuccessful and is considered to have been Churchill’s own initiative.Churchill was not an official member of the British peace delegation in Paris, but he took part in the negotiations on several occasions as head of the Ministry of War Material Supply and later the Ministry of War and Air.
