Wolfgang Mathis

Purpose This work is intended to historically commemorate the one hundredth anniversary of the invention of a new type of electronic circuit, referred to in 1919 by Abraham and Bloch as a multivibrator and by Eccles and Jordan as a trigger relay (later known as a flip-flop). Design/methodology/approach The author also considers the circuit-technical side of this new type of circuit, considering the technological change as well as the mathematical concepts developed in the context of the analysis of the circuit. Findings The multivibrator resulted in a “circuit shape” which became one of the most applied nonlinear circuits in electronics. It is shown that at the beginning the multivibrator as well as the flip-flop circuits were used because their interesting properties in the frequency domain. Originality/value Therefore, it is a very interesting subject to consider the history of the multivibrator as electronic circuits in different technologies including tube, transistors and integrated circuits as well as the mathematical theory based on the concept from electrical circuit theory.

Abstract The role of the diaries and memoirs in the process of the conscious self-reflection and their contribution to the emergence of modern individual personalities are well-known facts of the intellectual history. The present paper intends to analyze a special form of the creation of modern individual character; it is the self-creation of the writer as a conscious personality, often with a clearly formulated opinion about her/his own social role. There will be offered several examples from the 19th-century history of the Hungarian intelligentsia. This period is more or less identical with the modernization of the “cultural industry” in Hungary, dominated by the periodicals with their deadlines, fixed lengths of the articles, and professional editing houses on the one hand and the cultural nation building on the other. Concerning the possible social and cultural role of the intelligentsia, it is the moment of the birth of a new type, so-called public intellectual. I will focus on three written sources, a diary of a Calvinist student of theology, Péter (Litkei) Tóth, the memoirs of an influential public intellectual, Gusztáv Szontagh, and a belletristic printed diary of a young intellectual, János Asbóth.

Purpose The purpose of this paper is to provide an historical analysis of an important early contribution to the history of marketing thought literature – the six-book series titled The Knack of Selling – which was published in 1913 and intended as an early training course for salesmanship. Design/methodology/approach This research utilized a close, systematic reading of The Knack of Selling series and places it in the professional and intellectual context of the early twentieth century. Books published about marketing are primary source materials for any study of the history of marketing thought. In this case, The Knack series constitutes significant primary source material for a study of early thinking about personal selling. Findings Echoing A.W. Shaw, Watson offers a more sophisticated interpretation of the “one best way” approach associated with Frederick Taylor. Watson’s advice did not entail the repetition of canned sales talks to each customer. His vision of practice was more complicated. Sales presentations were temporally and locationally relative. They were subject to ongoing evolution. As the marketplace changed, as customer needs and interests shifted, so did organizational and salesperson performances. To keep sales talks relevant to the consumer, personnel were encouraged to undertake rudimentary ethnographic research and interviews. Unusually, there is oscillation in the way power relations between marketer and customer were described. While relational themes are present, so are military metaphors. Originality/value This is the first systematic reading of The Knack of Selling that has been produced. It is an important contribution to the literature inasmuch as this book set is not in wide circulation. The material itself was significant as an input into scholarship subsequently hailed as seminal within sales management.

Purpose – The continuous development of quality management in organizations was driven on the one hand by competition and on the other hand by growing requirements of the customers. Mass production with a pure push strategy changed to a more and more pull strategy with higher customer and market orientation. To satisfy the requirements of the triangle quality, cost and time the field of view of quality management has continuously been widened from considering “what” is done to “how” it is done. Nowadays the complexity and interrelations inside and outside of organizations increased with their global orientation. To face these global challenges, the purpose of this paper is to do a detailed analysis of the history of quality management that can support the initial position in development of specific tools and methods for quality improvement in organizations. Design/methodology/approach – For the historic analysis a well-founded literature review has been performed. After presenting the historical development of quality management, the current situation described. Finally an outlook for upcoming trends in quality management is provided by extrapolating current developments. Findings – Four different paradigm shifts in quality management are up to now identified and described, accompanied by a high number of smaller development steps. Current efforts for the further development of quality management encompass “perceived quality”, “human-focused quality management” and “intelligent quality management”. Originality/value – The paper gives a survey on the development of quality management and delivers a forecast on future requirements and trends in structuring the quality management in technical enterprises.

The subject of this research is the tendency towards formation of a new semiotic code of entertainment content, observed in the Russian segment of Tiktok social network. The goal of this research is to determine the new trends in recreational segment of the modern social network, the popularity of which depends on the number users’ likes and reposts. The research material contains the continuous sampling of videos for the period from February to March 2021. The analysis of videos of the Russian-speaking users allows revealing the tendency towards the emergence of a new type of recreational content at the intersection of plagiarism and parody. This implies voice-covering of the fragments of stand-up show in a different context: for example, a fragment from comedy show is lip-synced by a woman while preparing meal. In other words, the authors of such content do not claim to be original, they virtually lip-sync with synchronization of another person's speech (moreover, the TikTok format allows seeing the link to the original soundtrack). At the same time, such content is far from parodic, as there is no mimicking or gesturing of the original. This rather implies the renovation of the open text tradition, which historically accompanies the emergence of a new form of broadcasting information. Such content also indicates common features with the folklore: the author's story  is voice-covered by various users repeatedly, like an anecdote or the history of urban folklore. The conclusion is made on the emerging semiotic tendency of the polycode multimedia text, which on the one hand has deep historical roots, while on the other hand is substantiated by the modern technological capabilities and ways of broadcasting information.

The article draws attention to the fact that the phenomenon of marginality is the formation of one's own environment, although not completely dissolving into it. Traditional culture goes into the "basements" of society or manifests itself in the life and mentality of marginals. In a society affected by crisis, several cultural trajectories collide: descending, ascending and, for the marginalized, breaking traditional ties and creating their own, completely different world. In fact, marginality is the third culture, a special socio-cultural state. The article discusses its corresponding components. The prerequisites of global transformation are considered. The situation in Europe begins to change fundamentally at the turn of the I-II millennia. The formation of the era of European Transformation can begin with the XI-XIII centuries, when "Catholic" Europe appears. Phenomenal in its results was the "Renaissance of the XII century", the first truly pan-European Revival at the origins of the era of Transformation. With this, the movement towards a High Renaissance began. The Crusades (XI-XIII centuries) are particularly highlighted. After the Crusades, two variants of capitalism become promising and predominant in Europe and North America, and then their slow convergence continues. The XIII century became a milestone for contemporaries. On the one hand, Europe, it would seem, reached the end of history by creating some kind of optimal model. On the other hand, the reverse side of the idea of the "end of history" became clearly visible. The Mongols, having captured most of Eurasia, reformatted the ethno-political space. In this century, capitalist Europe is born, in fact, as a special development option. Highlighting the era of transformation does not mean that we should abandon the usual division of European history into known periods: antiquity, the Middle Ages, modern times. This periodization successfully emphasizes social and economic aspects and provides a chronological understanding of transitional processes. The era of Transformation is more voluminous, since we are talking about the transition from a centuries-old traditional society to a new stage of human development. Neither the Renaissance nor the Reformation created a new culture, the so-called bourgeois culture will have many faces, both international and national. The main thing is seen in the liberation of man from the former powerful civilizational model, Latin-Christian, i.e. Imperial-ecclesiastical, and ultimately - in the formation of a new type of man.

Purpose The paper aims to analyze the content of the newly published National AI Ethics Guideline in Thailand. Thailand’s ongoing political struggles and transformation has made it a good case to see how a policy document such as a guideline in AI ethics becomes part of the transformations. Looking at how the two are interrelated will help illuminate the political and cultural dynamics of Thailand as well as how governance of ethics itself is conceptualized. Design/methodology/approach The author looks at the history of how the National AI Ethics Guidelines came to be and interprets its content, situating the Guideline within the contemporary history of the country as well as comparing the Guideline with some of the leading existing guidelines. Findings It is found that the Guideline represents an ambivalent and paradoxical nature that characterizes Thailand’s attempt at modernization. On the one hand, there is a desire to join the ranks of the more advanced economies, but, on the other hand, there is also a strong desire to maintain its own traditional values. Thailand has not been successful in resolving this tension yet, and this lack of success is shown in the way that content of the AI Ethics Guideline is presented. Practical implications The findings of the paper could be useful for further attempts in drafting and revising AI ethics guidelines in the future. Originality/value The paper represents the first attempt, so far as the author is aware, to analyze the content of the Thai AI Ethics Guideline critically.

Purpose By studying the marketing of advertising space, this paper aims to study how class, gender and region were portrayed in terms of economic considerations in adverts selling advertising space to potential advertisers. The paper studies how readers were discursively transformed into consumers in this material and how different consumer groups were depicted, divided and framed during Sweden’s early consumer culture. By doing so, the paper highlights the tensions between aiming at a mass audience, on the one hand, and striving to reach more and more specific consumer groups on the other hand. Design/methodology/approach Both qualitative and quantitative analyses are made in order to follow the changes of highlighted consumer groups in the ads. Intersectional analysis is used to see how notions of class and gender intersected during the analysed period. Findings The sectioning of the press is in the paper stressed as a prerequisite for market segmentation and the economic history of mass media is lifted as essential for understanding it. The gendering and classing of market segments were also based on how common interests were interpreted by political movements and their press forums. For surviving in the long run, however, the paper argues that the political press needed to commercialise their readerships to attract advertisers and survive economically. Originality/value The paper concludes that mass marketing and segmentation processes were in many senses parallel in the studied material. Statements of reaching all social classes diminished over time, but notions of the masses were prevalent in both the worker and the women categories. However, how advertisers choose between different media for their advertising campaigns or how they adopted different marketing methods towards different segments are beyond the scope of this paper.

Purpose During the first quarter of the twentieth century in Russia rapidly developed management thought, generated by many reasons, including socio-economic and political transformations, the results of scientific and practical activities of domestic and foreign experts in management. The purpose of this paper is, first, to acquaint readers with some of factors of the development of the history of Russian Management Thought in nineteenth century and at the beginning of twentieth century and, second, to present the most striking results of the formation of the History of Soviet Management Thought (SMT) in post-revolutionary Russia in the form of the movement of the so-called “The scientific organization of labor” (SOL), including “The scientific organization of managerial labor” (or SOML). Design/methodology/approach The review and causal analysis of the process of formation of the SMT and historiography of the SMT, a brief description of the institutions of SOL and SOMT and a comparative analysis of little-known works of some Russian authors on management topics of nineteenth century are chosen as research methods. Findings The paper emphasizes the action of objective historical inertia (or “non-Markoviness”) of the process of development of managerial thought, manifested, on the one hand, in the stable action of some management paradigms but, on the other hand, in identifying paradigmatic anomalies, in identifying the need for constant development of managerial thought, in the development of sought-after ideas and concepts of management, and even in the institutionalization of applied scientific research in the field of management throughout the country (in the form of SOL and SOML). Originality/value The paper attempts to attract the attention of researchers to the little-known Russian and Soviet authors and their little-known works in the field of management thought.

Purpose – The purpose of this paper is to analyze the circumstances that have conditioned the development of education in Spain from the enlightenment to the present day. Design/methodology/approach – Multidisciplinary scientific approach that combines the interpretation of the legal texts with the revision of the doctrinal and theoretical contributions made on the issue. Findings – From the beginning of the nineteenth century, the history of education in Spain has been marked by constant fluctuations between the reactionary instincts, principally maintained by the Catholic Church and the conservative social classes, and the progressive experiments, driven by the enlightened and the liberals first, and the republicans and the socialists later. As a consequence of that, the fight for finishing with illiteracy and guaranteeing universal schooling underwent permanent advances and retreats, preventing from an effective modernization of the Spanish educative system. On the one hand, renewal projects promoted by teachers and pedagogues were inevitably criticized by the ecclesiastical hierarchy, obsessed with the idea of preserving the influence of religion on the schools. On the other hand, successive governments were weak in implementing an educational policy which could place Spain at the level of the other European and occidental nations. Originality/value – At the dawn of the twenty-first century, although the country has overcome a good part of its centuries-old backwardness, increasing economic difficulties and old ideological splits keep hampering the quality of teaching, gripped by neoliberal policies which undermine the right to education for all. The reading of this paper offers various historical clues to understand this process.

PurposeExpanding the research on traditional history of economic ideology into the research on the history of economics composed of three elements – history of ideology, history of policies and events – is a new idea for researching the history of socialist political economy with Chinese characteristics. The start of the history of socialist political economy with Chinese characteristics is consistent with that of the Sinicization of Marxist political economy and can be dated from at least 1917.Design/methodology/approachThe key point of the research on the history of ideologies of the socialist political economy with Chinese characteristics is to treat the relationship between theory and people properly, i.e. we should not neglect the effect brought out by the economists on theory construction while we attach importance to the theoretical contribution of the leaders and leading group of the Communist Party of China (CPC).FindingsFor the research on the history of economic policies of socialist political economy with Chinese characteristics, on the one hand, we should clarify the relationship among ideologies, strategies and policies; on the other hand, we should not evade the summarization of lessons from history.Originality/valueBesides presenting the development route of socialist political economy with Chinese characteristics under competition, the research on the events in the history of socialist political economy with Chinese characteristics should also help develop the socialist political economy with Chinese characteristics.
