Despite a few attempts to automatically crawl Ewe text from online news portals and magazines, the African Ewe language remains underdeveloped despite its rich morphology and complex "unique" structure. This is due to the poor quality, unbalanced, and religious-based nature of the crawled Ewe texts, thus making it challenging to preprocess and perform any NLP task with current transformer-based language models. In this study, we present a well-preprocessed Ewe dataset for low-resource text classification to the research community. Additionally, we have developed an Ewe-based word embedding to leverage the low-resource semantic representation. Finally, we have fine-tuned seven transformer-based models, namely BERT-based (cased and uncased), DistilBERT-based (cased and uncased), RoBERTa, DistilRoBERTa, and DeBERTa, using the preprocessed Ewe dataset that we have proposed. Extensive experiments indicate that the fine-tuned BERT-base-cased model outperforms all baseline models with an accuracy of 0.972, precision of 0.969, recall of 0.970, loss score of 0.021, and an F1-score of 0.970. This performance demonstrates the model’s ability to comprehend the low-resourced Ewe semantic representation compared to all other models, thus setting the fine-tuned BERT-based model as the benchmark for the proposed Ewe dataset.

The aim of the Hungarian state socialist regime to renew the operetta art manifested in the transformation of operetta-playing via the setting of its main cultural objectives. Once private theatre organizations were disbanded in 1949, newly written and composed operetta pieces had to be adjusted to meet the expectations cultivated by those responsible for the drawing up of the contemporary cultural policies, not only in terms of theme, subject, and dramaturgy but also, as productions designed for stage performance. At that time, questions regarding the realm of operetta dance and choreography arose as significant professional issues. The remarkable case of operetta dance was brought to the notice of the larger professional community by an article written by choreographer Ágnes Roboz, which was published in 1952 in the Táncművészet magazine (1951). Due to its professional nature, this magazine served as a suitable platform for the discussion of the operetta dance genre. The present study reflects upon its publications from the period between 1952 and 1956. Throughout these years, 16 articles discussing the categorization of operettas were published. I aimed to analyze these primary sources according to their genre before presenting, juxtaposing, and contextualizing them. Thus, my objective is to gain a thorough understanding and comprehensive overview of professional discussions and arguments over 1950s operetta dances and choreographies. Full article

In 1969, English researcher Gordon Pask published an article named “The Architectural Relevance of Cybernetics”, defining a theoretical framework concerning a cybernetic theory of architecture. Throughout the 1970s, the Cambridge Research Group designed the Autonomous House, a self-sufficient dwelling in terms of energy and food. Part of the Cambridge group approach relates to cybernetics. However, the group did not regard several aspects of cybernetics described in the theoretical framework of Pask. Through a literature review primarily focused on 1970s architectural magazines, this paper analyses which cybernetic aspects were not regarded in the Cambridge Autonomous House and other similar houses as case studies. Through an innovative analytical method, it demonstrates that some limitations of the house design, such as the main focus on costs and technologies, could have been reduced if aspects of cybernetics had been more incorporated. Using cybernetics as a lens represents a method which can be beneficial also in analysing today’s examples of sustainable and autonomous architecture. Full article

The study aims to contribute to our understanding of the situation of languages in contact and the phenomenon of linguistic borrowings in the modern online world. The current study investigates the use of English terms borrowed to describe romantic relationships in Spanish. We use a list of terms presented in GQ Spain, a men’s culture, fashion and style magazine, as popular terms in 2020 to describe (a lack of) love in romantic relationships. In order to analyze the actual use of these borrowings in Spanish, we collected data from the Corpus del Español NOW (2012–2019), focusing on the number of occurrences of each English borrowing, level of morphological adaptation, co-occurrence of translations or explanations, date of first use and location of use. Overall, 11 of the 20 terms, such as ghosting, gaslighting or benching, appeared in the corpus. We note the presence of quotation marks, parentheses or uppercase letters in some cases, but it was observed that most examples keep their English form. However, many terms appeared with an explanation or translation, reflecting the novelty of the borrowing. Data regarding dates and countries were collected in order to set the year they were integrated with the new meaning (2013–2019). The country with the highest number of cases was Argentina, and there were a substantial number of cases in other Spanish-speaking countries. Overall, these findings show an increase in the incorporation of these borrowings over the years in the Spanish lexicon. Full article

We live in a complex world characterised by complex people, complex times, and complex social, technological, economic, and ecological environments. The broad aim of our work is to investigate the use of ICT technologies for solving pressing problems in smart cities and societies. Specifically, in this paper, we introduce the concept of deep journalism, a data-driven deep learning-based approach, to discover and analyse cross-sectional multi-perspective information to enable better decision making and develop better instruments for academic, corporate, national, and international governance. We build three datasets (a newspaper, a technology magazine, and a Web of Science dataset) and discover the academic, industrial, public, governance, and political parameters for the transportation sector as a case study to introduce deep journalism and our tool, DeepJournal (Version 1.0), that implements our proposed approach. We elaborate on 89 transportation parameters and hundreds of dimensions, reviewing 400 technical, academic, and news articles. The findings related to the multi-perspective view of transportation reported in this paper show that there are many important problems that industry and academia seem to ignore. In contrast, academia produces much broader and deeper knowledge on subjects such as pollution that are not sufficiently explored in industry. Our deep journalism approach could find the gaps in information and highlight them to the public and other stakeholders. Full article

International metropolises are key sites of outbreaks of COVID-19 cases. Global public evaluation of the pandemic in international cities is affected by many factors. This study examines how media exposure affects this evaluation and how media trust and media bias perception moderate the relationship between them. Based on an online survey of the evaluation of 13 international cities’ pandemic performances by 1171 citizens from 11 countries, this study conducted a multi-level stepwise regression analysis and discovered that: (1) different forms of media affect global citizens’ perceptions of international metropolis COVID-19 pandemic performance differently; and the role of traditional paper media, including newspapers and magazines, is of little significance in comparison to electronic media. (2) Among electronic media, TV and broadcasting have the greatest impact, followed by social media and the Internet. (3) Media trust and media bias perception affect people’s evaluations of international urban pandemics, but our survey reveals that they only function with regard to social media. Full article

Environmental problems at the global level have become a critical issue in today’s fashion industry. However, small-and medium-sized fashion business (SMFBs) encounter barriers in promoting green business owing to finances, professional expertise, knowledge, and technology. Therefore, innovative ideas are vital for SMFBs to effectively address constraints to compliance. The purpose of this research is to analyze how SMFBs develop the interactive nature of value propositions based on the case studies of the Onomichi Denim Project and the REKROW and addresses what elements are associated with value propositions based on the human-centered perspectives. This study collected data through face-to-face and remote interviews, and a review of the previous literature, including magazines, websites, and videos. This study identified four value elements contributing to value propositions: environmental value, embedded social value, synergetic value, and educational value. These elements developed through various forms of interaction, such as a unique co-production system embedding social ties and the establishment of a production-oriented circular economy. The study proposed value creation through value proposition as a strategy crucial to managing SMFBs. Full article

This article, as the fourth in the cycle, presents the conclusions of the research project analysing marketing activities of Polish Catholic opinion-forming weeklies on the chosen social media platforms. This paper aims at presenting the results of the study on the use of Instagram and YouTube as marketing tools by the aforementioned weeklies. The authors focus on such topics as: (1) social media as a way of creating and distributing media products; (2) social media as a way of commercialising the content; (3) social media as carriers of marketing communication (including self-promotion). The empirical research is based on case studies and the content analysis of the social media profiles of the five selected magazines (Gość Niedzielny (GN), Tygodnik Katolicki Niedziela (TKN), Przewodnik Katolicki (PK), Idziemy (I) and Tygodnik Rodzin Katolickich Źródło (TRKŹ)). It can be concluded that some Catholic weeklies manage their accounts in a moderately professional way, using their visual and distribution potential and some functions of the platforms quite efficiently. On the other hand, they do not apply a regular and purposeful self-promotion strategy, do not use important mechanisms of the platforms such as the Shop and IGTV (on Instagram), and do not consistently build a profile or create playlists on YouTube.

The lack of examples of smart-city initiatives and the sharing of best practices in Portugal confirm the gap in the transference of empirical knowledge to the scientific literature in this area. The smart-city concept has passed through three stages. However, its evolution has not been noted equally throughout countries and their territories. The literature only provides information about specific projects implemented in a few cities. Therefore, the aim of this paper was to study the state-of-the-art of smart cities in Portugal by analyzing 25 editions of the most relevant national-wide smart-cities magazine. First, the objective of analyzing the magazine was to study each Portuguese city in terms of the subject areas and types of existing initiatives in order, ultimately, to frame cities within their respective smart-city phases, as per the literature. Second, the aim of the paper was also to provide information about the evolution of the concept through analyses of embedded experts’ quotes. The results of the first are complemented with the analysis of interviews with policymakers to provide information about the existing challenges to implementing a smart city and to understand the role of government therein. Qualitative and quantitative analyses were performed on the case study. The findings suggest that the three smart-city phases are perceived in slightly different ways in Portugal and heterogeneity within the country can be noted from the lack of strategies and a standard framework.

Reducing food wastage is one of the challenges in achieving global food security and transforming current food systems. Since human nutrition is closely dependent on cereal production, research was undertaken aimed at understanding the food losses in the baking and confectionery industry (BCI) in Poland, in particular at determining the volume, reasons and ways of reducing losses, identifying possibly all of the reasons for losses in BCI using the Ishikawa 5M + 1E diagram and determining the level of significance and probability of risk of food losses in the analysed sector. Two research methods were used. Quantitative data were collected using the mass balance method from five businesses that served as case studies. Qualitative data were collected through individual in-depth interviews with 17 industry experts. The companies’ average daily losses ranged from 0.8 to 6.4 tons, representing 9.7 to 14.4% of production volume, including 10.4–13.4% of bread losses and 6.8–24.4% of fresh pastry losses. The highest losses were generated by transport departments and these were exclusively retail returns. Following the Ishikawa concept, 31 primary and 94 secondary reasons for food losses were identified. Using the probability of loss risk, a toolkit for loss prevention and mitigation across all departments within businesses (raw materials magazine, production section, final product magazine and final product transport) and a set of horizontal tools were identified, including specialised training for employees and activities in several areas, e.g., technical status and production technology, organisation and planning, logistics and sales and cooperation with retail. This study, conducted in Poland, offers valuable results for developing programmes and strategies to prevent and manage food losses in BCI. Many of the solutions proposed in both toolkits can bring economic benefits without involving additional high costs. Full article

This article presents the partial conclusion of the research project devoted to marketing activity of Polish Catholic opinion-forming weeklies on the social media platforms. The main aim of this article is to present the results of the study on the use of Twitter as a marketing tool by Polish nationwide Catholic opinion-forming weeklies. The basic research questions concerned the extent of utilizing the platform by the magazines’ editors to create and distribute the content of their media product, maintain and develop brand communication and self-promotion. The case studies and the content analysis of the accounts of the three magazines—Gość Niedzielny, Tygodnik Katolicki Niedziela and Przewodnik Katolicki—show that there are three different ways in how the editors of the magazines understand the role of the Twitter account of the title they represent—as an ‘active communicator’, ‘active communicator and community supporter’ or ‘community supporter’. The conclusions show that the studied media fairly efficiently use the visual and distributional potential of the platform as well as some of its features, at the same time missing the chance to build a brand-loyal community. They also limit the role of Twitter to that of a supplement for the main communication channel, which is the printed weekly and its website. Full article

Since the 2000s, Japanese internet media as well as mass media, including magazines, television and newspapers, have promoted the concept of a “power spot” as part of the spirituality movement in the country. This emerging social environment for the power spot phenomenon has developed a new form of religiosity, which can be called “spiritual legitimacy,” according to the transformation of religious legitimacy embedded in Japanese society. This paper, therefore, examined the emergence of a new form of spiritual legitimacy utilizing a case study of the power spot phenomenon in the Haruna Shrine, Gunma Prefecture, in Japan. The development of the power spot phenomenon in the Haruna Shrine indicates that consumption of spiritual narratives has strongly promoted the construction of a social context of spiritual legitimacy, such as through shared images and symbols related to the narratives in the sacred site. As a result, this paper clarifies that this new form of spiritual legitimacy embodies stakeholders’ social consensus on spiritual narratives, which people have struggled to construct a social context for spiritual legitimacy to ensure hot authentication of their individual narratives and experiences.

The creation of digital repositories for archiving and disseminating scientific resources faces many challenges. These challenges relate not only to the modelling of the processes of preparing, depositing, sharing, maintaining, and curating resources. They also face the feasibility of the adopted assumptions and final implementation. Such kind of issues become particularly important in the case of processing of resources containing multimedia. The critical factor then becomes a properly designed architecture that supports efficient data processing and universal data presentation. This article aims to answer questions that may arise when approaching various designing and implementation dilemmas, such as how to handle processes in a digital repository, how to use cloud solutions in its construction, how to work with user interfaces, and how to process collected multimedia. The presented study explores their practical context based on the experiences gained during the AZON platform’s implementation. This platform stores tens of thousands of scientific resources: books, articles, magazines, teaching materials, presentations, photos, 3D scans, audio and video files, databases, and many more. It serves as a running example for all presented proposals. Full article

The latent heat thermal energy storage units are very popular because of their high energy density and almost close to constant temperature during the charging/discharging. In the present study has been proposed new shell-and-coil geometry with a shifted coil position to enhance the performance of phase change thermal magazine. The experimental investigations have been performed both for the melting and solidification process of coconut oil for constant wall temperature conditions. The experiments have been carried out for cylindrical as well as coil shape geometry of the TES unit. In the case of annular TES, the copper tube with outer diameter d = 10 mm and total length equal to 165 mm were used (4). In the case of shell-and-coil TES the coil has been also made of a copper tube but with an outer diameter d = 6 mm. The total length of the tube was 460 mm. However, the length of the tube element that has been used in the process of bending the coil had a total length equal to 360 mm. The rest of the tube was straight. The coil pitch was 15 mm and the outer coil diameter was 26 mm. The experiments have been conducted for the coil position at the top and the bottom of the tank. The results showed the influence of heat transfer geometry for phase change efficiency. The article presents the thermal characteristic of melting and solidification phenomena as well as their visual analysis. A significant impact of heat transfer geometry at the shape of the melting and solidification profile. The optimal performance has been achieved for shell-and-coil TES with a coil arranged at the top of the tank. Full article

On 15 July 2020 was the 15th anniversary of the Science Magazine issue that reported three trypanosomatid genomes, namely Leishmania major, Trypanosoma brucei, and Trypanosoma cruzi. That publication was a milestone for the research community working with trypanosomatids, even more so, when considering that the first draft of the human genome was published only four years earlier after 15 years of research. Although nowadays, genome sequencing has become commonplace, the work done by researchers before that publication represented a huge challenge and a good example of international cooperation. Research in neglected diseases often faces obstacles, not only because of the unique characteristics of each biological model but also due to the lower funds the research projects receive. In the case of Trypanosoma cruzi the etiologic agent of Chagas disease, the first genome draft published in 2005 was not complete, and even after the implementation of more advanced sequencing strategies, to this date no final chromosomal map is available. However, the first genome draft enabled researchers to pick genes a la carte, produce proteins in vitro for immunological studies, and predict drug targets for the treatment of the disease or to be used in PCR diagnostic protocols. Besides, the analysis of the T. cruzi genome is revealing unique features about its organization and dynamics. In this work, I briefly summarize the actions of Latin American researchers that contributed to the first publication of the T. cruzi genome and discuss some features of the genome that may help to understand the parasite’s robustness and adaptive capabilities.
