Barriers to digital transformation of high and medium high tech global manufacturing enterprises in Poland
Full text linkThe aim of the study is to identify the key barriers to digital transformation and assess the structure of interrelations between these barriers and the selected characteristics of enterprises, their approach to digital transformation, as well as the technological advancement of products in large and very large foreign manufacturing enterprises operating in the high and medium high technology sectors in Poland. The empirical research is based on information from 95 survey respondents. Multidimensional correspondence analysis was applied in the research to simultaneously assess the structure of interrelations between the categories of multiple nominal variables. The conducted research shows that more than 50% of the surveyed enterprises indicated excessive costs of digitalization as the main barrier to its implementation, followed by uncertain market conditions and lack of own financial resources. The most significant difficulties related to the implementation of digitalization were primarily experienced by the enterprises operating in Poland for up to 10 years, free to relocate, not committed to develop innovative products, and presenting negative approach to digital transformation. The research findings provide crucial information useful for businesses, politicians, researchers and technology providers in creating more effective strategies and policies to support the Industry 4.0 development. It can contribute to increased business competitiveness and innovation, thus having a positive impact on the economy in general. The article constitutes an original study based on the authors’ own research.

Value-added manufacturing, growth and inflation: dynamic panel threshold perspective
Full text linkThis study pioneers the exploration of inflation’s nonlinear role in the nexus between value-added manufacturing and economic growth, employing a dynamic panel threshold model for 38 Organisation for Economic Co-Operation and Development (OECD) countries from 1980 to 2023. Unlike prior research, it uniquely identifies an inflation threshold (4.4954%) that alters the manufacturing-growth relationship. Below this threshold, value-added manufacturing significantly boosts economic growth, while above it, growth declines despite manufacturing process, revealing a novel nonlinear dynamic. Utilizing advanced methodologies like System Generalized Method of Momemnts (GMM) and Diallo’s (2020) dynamic panel threshold approach, the study addresses endogeneity and cross-sectional dependence, offering robust insights. These findings highlight inflation’s critical influence on manufacturing’s growth effects, urging policymakers to prioritize price stability to maximize manufacturing’s economic contributions. This research enriches the literature by integrating inflation thresholds into growth models, providing fresh policy implications for sustainable economic strategies in OECD economies.

Rock subculture in Žilvinas Glušinskas’ photographs: building communal capital through creative documentary
Full text linkThe historical background of the rock subculture’s political engagement and cultural relevance in Lithuania, along with photography’s role in shaping and establishing society’s collective identity, suggests that the study of contemporary photography related to this subculture may offer insights into broader societal developments and photography’s function within them. Building on this premise, the article explores Žilvinas Glušinskas’ photography series The Bash at Mekanikas’ Fazenda (orig. in Lithuanian (irregular language use with jargon): Tūsas pas Mekaniką fazendoje, 2019–2024) with the aim of defining how photography represents and shapes a specific rock subculture community and its connection to wider society today. To address this, the study analyses the documentary, artistic and cultural aspects of Glušinskas’ works, as well as the different contexts and media through which they are disseminated. The research is based on sociologist Sarah Thornton’s notion of subcultural capital, which in turn stems from the concept of cultural capital defined by sociologist Pierre Bourdieu. The article concludes with a statement that creativity in photography, combined with its documentary value and the dissemination of photographs through mass and micro media, becomes a tool for generating communal capital – a symbolic meaning shared by a group of people, binding them into a community in a diverse and fragmented society

In analyzing architectural research connected to doctoral education, but also to the second cycle of higher education, the paper describes the Design Studio as the ideal place where teaching, research and learning can blend in to produce innovative and meaningful forms of knowledge
Global advancements in BIM-based building e-permit system adoption: a review
Full text linkGlobally, several countries have begun to promote the application of building information modeling (BIM) technology and implement BIM-based building e-Permit systems. Despite the relatively rapid updates in the field of BIM-based building e-Permit systems, currently a lack of systematic sorting and summarization exists. This review evaluates the situation of seven representative countries from three aspects: the current adoption status of the BIM-based building e-Permit system, adoption background (BIM-related policy, roadmap, standards, and guidelines), and a future development plan for digital construction. These three aspects are analyzed, common measures across these countries are summarized. Four viewpoints are extracted for promoting BIM-based building e-Permit system adoption, which are mandatory policy orientation, standardization, internationalization, and intelligence. Finally, as the integration of AI into BIM-based building e-Permit systems is a recent research trend, this study also investigates existing research, highlights bottlenecks and points out future directions for AI integration

Arts-based education to develop creativity in Lithuania: insights from public policy theories
No full textThis study is a critical overview of the Lithuanian system of arts-based education, which provides conditions for the development of creativity in children and young people. The aim of the study is to provide an analysis of the ongoing transformations, changes, and tensions that are emerging in the field of an arts-based education in Lithuania. The authors analyze the particular case of arts-based education with reference to several theoretical public policy frameworks. Insights gained from the historical institutionalist approach illuminate the path dependency that favors institutionalized, centralized, elitist forms of traditional arts-based education, such as music and fine art schools. This system maintains centralized funding that allocates money from national and local authorities to long-established institutions of arts-based education. The punctuated equilibrium framework developed by Baumgartner and Jones (1993) in their book Agendas and Instability in American Politics has highlighted the reform of the national curriculum, the neoliberal education policies, the diversification of providers and services, the increased emphasis on client choice and their financial participation, administrative and fiscal decentralization with the introduction of student baskets in general, non-formal and higher education as turning points, and critical junctures that fundamentally changed the entire structure of the education system in Lithuania. Based on the multiple streams framework developed by John W. Kingdon in his book Agendas, Alternatives, and Public Policies (originally published in 1984), the analysis revealed that the Lithuanian arts-based education system has unfortunately not gained new momentum but rather operates under the influence of general education and cultural policy decisions. The advocacy coalition framework developed by Paul A. Sabatier and Hank C. Jenkins-Smith in their book Policy Change and Learning: An Advocacy Coalition Approach revealed how heterogeneous groups of actors (i.e., students and parents, art teachers and educational administrators, and entrepreneurs in the educational market of arts-based education) participated in the process of implementing neoliberal policies, changes in educational funding, and the commodification of education
Investment implications of Industry 4.0: evidence from smart manufacturing ETFs
No full textThe rise of smart manufacturing, driven by digital transformation and Industry 4.0, has introduced new opportunities for investors seeking to diversify their portfolios. Smart manufacturing ETFs offer a unique risk-return profile tailored to the evolving landscape of industrial automation and data-driven processes. This paper explores the comparative risk-adjusted performance of a smart manufacturing ETF, a conventional industrial portfolio, and a broad-market SP500 tracking portfolio, utilizing daily data from October 2019 to October 2022. By deconstructing the excess returns of these portfolios through one-factor, three-factor, and five-factor asset pricing models, we provide insights into the risk exposure and performance drivers of smart manufacturing investments. Results indicate that investing in smart manufacturing, while less performant relative to the other investments, carries less exposure to market risk and can provide important diversification benefits to equity portfolios. Moreover, there is a positive loading for the size factor and a negative loading for the value and profitability factors for the smart manufacturing portfolio during a period of positive premium for all factors except for size. This implies that the consequent payoff in terms of profitability will eventually turn the loading of the profitability factor into positive territory, increasing returns on smart manufacturing investing
Multidimensional cost analysis of Europe–Asia container transport routes
Full text linkIn this article, we propose a 3-dimensional framework for evaluating the costs of transporting goods between Europe and Asia, including direct transport, time, and Environmental Costs (ECs). We estimate the costs of alternative container transport routes, including direct sea transport via the Suez Canal Route (SCR) and the Northern Sea Route (NSR); direct rail connections via the Trans-Siberian Rail (TSR) and the Belt and Road Initiative (BRI), and intermodal transport options consisting of rail and sea transport legs. When considering environmental and Inventory Carrying Costs (ICs), the NSR is viable at least seasonally, whereas rail and intermodal alternatives remain more expensive. The results provide a robust estimate of the potential of alternative transport routes and modes. The inclusion of ECs in our analysis provides valuable new information to stakeholders on how to achieve the ambitious environmental goals while also considering the economic viability of different route options in Europe–Asia container trade
Health status assessment and fault warning methods for aircraft engines under time varying operating conditions
Full text linkWith the growth of the aviation transportation industry, aircraft engines, as the core components of flight safety, are facing increasingly severe challenges in health status assessment and fault warning technology. To achieve accurate evaluation and fault warning of engine status, this study proposes a new method using improved multi-channel network and hybrid network models. The new method can achieve life prediction and evaluation of engine health status in different time-varying scenarios by improving the multi-channel network. Meanwhile, the method achieves early warning of operational faults by using a hybrid network model for real-time analysis of aircraft engine operation data. The results demonstrated that the new method had root mean square errors of only 12.35 and 12.84 on different datasets, significantly better than other models. The score of the new model has also significantly decreased, with accuracy rates of 91.5% and 93.4% on different datasets, far exceeding other models. Moreover, although the new model had a large number of parameters, it had short training time, low latency, small memory usage, and excellent system performance. The new method can significantly improve the health status assessment and fault warning of engines, which has good guiding significance for achieving stable operation of aircraft engines
