Alignment of innovation diffusion and project management to increase logistics digitalization
Get PDFPurpose – This paper examines how integrating Innovation Diffusion Theory (IDT) with structured project management frameworks enhances digital technology adoption in logistics, addressing challenges in ineffective implementation.
Research methodology – A mixed-methods approach combines qualitative interviews with logistics executives and technology experts with quantitative analysis of adoption trends using case studies and industry data.
Findings – Results highlight the complexity of digital technologies and emphasize aligning decision-making frameworks – Agile, Scrum, Kanban, and Waterfall – with organizational goals to improve digital transformation. Structured project management methodologies help firms manage complexity, mitigate risks, and optimize project execution.
Research limitations – The study does not analyze all technology complexity levels or include all digital solutions in logistics. Additionally, not all technologies were linked to expert-identified success factors, limiting generalizability. Future research could use longitudinal or case-study approaches to explore long-term impacts.
Practical implications – Integrating IDT with project management frameworks and the Stacey Matrix helps logistics firms overcome adoption barriers and improve implementation success.
Originality/Value – This research provides empirical evidence on structured decision-making in digital adoption. By integrating expert insights and correlation analysis, it offers practical recommendations for optimizing innovation diffusion, mitigating risks, and aligning technology implementation with strategic goals in a rapidly evolving digital landscape
Effects of technology-enhanced active learning on the musical creativity of gifted students
Get PDFTechnology-enhanced active learning increases not only gifted students’ interest in learning but also facilitates the promotion of their musical creativity. This study uncovers gifted students’ attitude toward technology-enhanced active learning and its effect on their musical creativity. This mixed-methods study used an experimental design followed by semi-structured interviews. We developed a control group (n = 19) and an experimental group (n = 21) of the randomly selected gifted students’ age of 11–13 years old from science and art centres institution at secondary schools in Turkey. We designed an intervention to deliver music curricula through technology-enhanced active learning for the experimental group and without technology-enhanced active learning for the control group. Three experts used a rubric to measure the musical creativity of gifted students. A pre-test and post-test indicated that there was an effect of technology-enhanced active learning on the musical creativity of gifted students. Semi-structured interviews with students also suggested that gifted students have positive attitude towards technology-enhanced active learning. Students have a positive attitude towards the technology-enhanced active learning approach owing to five reasons: finding education programs beneficial, self-expression, improvement in composing skills, improvement in using technology while composing, and eagerness to continue technology-enhanced active music learning
Art-technologies for creating an artistic image: issues of imitation and the transitivity of the creative process
Get PDFThe article reveals certain aesthetic patterns in the creation of augmented reality content, namely the importance of modelling the real environment, transitivity, and simulation of traditional practices of creating sculptural forms. These issues are analyzed on the author’s projects examples organized through the augmented reality use (applications REMS Companion App and MININ Art). An aesthetic patterns interdisciplinary research of augmented reality content perception allows us to draw significant conclusions about the artistic uniqueness of virtual images. The article reveals certain regularities in the creation of augmented reality content, including the peculiarities of imitation of traditional sculptural techniques and materials texture. It has been established that in order to create a realistic embodiment of virtual models in a real environment and to make these objects three-dimensional, it is important to take into account the peculiarities of chiaroscuro. Technologically, this can be done by installing a light source in the virtual scene that will illuminate objects at a certain angle. Consideration of the results of technological experience of content generation suggests that augmented reality allows the artist to create a transitional creative environment by imitating real space. When virtual content is detached from its marker (the image of real space), the specific author’s context is lost. As a result, we can safely talk about the content uniqueness created with the help of augmented reality technology. Having all the signs of artistic creativity, these models can be called augmented reality sculptures – a form of synthetic digital and visual art
Creative approaches in making objects of identification for Ukrainian companies
Get PDFThe article is devoted to the study of creative approaches of design and advertising specialists in creating logos and trademarks of the companies of Ukraine, other countries of Europe, North America, and the East Asia, that have been successfully operating in the market for at least ten years. Examples of font and image solutions aimed at solving a set of problems have been considered: brand identification among others, product or service advertising, forming the visual image of the company in the consumer’s mind. The authors believe that the environment of visual signs and messages is a system of various human impressions, indications of needs, and ways to meet them, which requires a “creator”, endowed with the gift of intuitive insight into the pictorial essence of things, needs and phenomena and able to convince consumer in the understanding of their image. Logos of various global companies (manufacturers of food, industrial, pharmaceutical products, service companies and others) are classified into eight groups by structural and compositional characteristics. Based on the analysis of market positioning of companies and their communication strategies, the authors conclude that the basis for identifying the creative component in the development of brand identity is the relationship between production processes and positioning of goods (services) and the sensory-emotional sphere of the consumer
The creativity of monuments: the case of bistable Belarusian identity
Get PDFDuring the last decades, Belarus has experienced a wave of monument construction, i.e., the monuments as creative practices through which certain historical, cultural and political meanings are constructed and articulated. The process confirms some scientists’ insights that the Belarusian identity is actively created today. However, the scientists who are interested in its construction on a practical level have not paid attention to the process of monument creation in Belarus as it also creates and articulates state identity. The analysis of the monument-making process has revealed that three identity narratives co-exist in Belarus: national-cultural and two political-historical ones, i.e., commonality with Russia and political independence from Russia. The potential contradiction of these political-historical narratives shows that the Belarusian identity is in a dichotomous and uncertain state. Although the spread of the political independence from Russia narrative allows us to talk about the existence of an independent national identity of Belarus (one of the most prominent manifestations was the mass protests in 2020, unpredicted by many scientists) in parallel with the existence of a strong historical-political narrative of commonality with Russia, the identity of Belarus remains in a bistable condition. For this reason, the further development of the Belarusian identity remains uncertain in the long-term perspective
Investigation of the Africa splitting into two as new ocean forms
Get PDFScientists believe that Ethiopian tectonic plate changes indicate that Africa is breaking apart, opening the path for the emergence of the planet’s sixth ocean. Ever since the East African Rift, a 35-mile-long fissure in Ethiopia’s desert, appeared in 2005, there has been a continuous movement between the tectonic plates. The second-largest continent in the world will virtually split in two due to the separation of the Somalian tectonic plate from the larger Nubian tectonic plate. This event has not been seen in hundreds of millions of years, when South America and Africa were separated into separate continents. The Somali and the Nubian tectonic plates are slowly disintegrating from each other, while the Arabian plate continues to pull away. The continental rift will happen along the east African Rift Valley, a geologically active region whose formation millions of years ago is similar to that of the tectonic movements that happen at the bottom of oceans. This means landlocked countries such as Rwanda, Uganda, Burundi, the Democratic Republic of Congo, Malawi, and Zambia would inadvertently find themselves with a coastline, and thus, build harbours that connect them to the rest of the world directly. Kenya, Tanzania, and Ethiopia would have two territories each. Though that will take between five to 10 million years, the continent will eventually split into two sub-continents, creating a new ocean basin between them
Numerical differentiation of fractional order derivatives based on inverse source problems of hyperbolic equations
Get PDFIn this paper, we mainly study the numerical differentiation problem of computing the fractional order derivatives from noise data of a single variable function. Firstly, the numerical differentiation problem is reformulated into an inverse source problem of first order hyperbolic equation, and the corresponding solvability and the conditional stability are provided under suitable conditions. Then, four regularization methods are proposed to reconstruct the unknown source of hyperbolic equation which is the numerical derivative, and they are implemented by utilizing the finite dimensional expansion of source function and the superposition principle of hyperbolic equation. Finally, Numerical experiments are presented to show effectiveness of the proposed methods. It can be conclude that the proposed methods are very effective for small noise levels, and they are simpler and easier to be implemented than the previous PDEs-based numerical differentiation method based on direct and inverse problems of parabolic equations
Discrete universality theorem for Matsumoto zeta-functions and nontrivial zeros of the Riemann zeta-function
Get PDFIn 2017, Garunkštis, Laurinčikas and Macaitienė proved the discrete universality theorem for the Riemann zeta-function shifted by imaginary parts of nontrivial zeros of the Riemann zeta-function. This discrete universality has been extended to various zeta-functions and L-functions. In this paper, we generalize this discrete universality for Matsumoto zeta-functions
A new method to solve multi-objective linear fractional programming problem in fuzzy stochastic environment
Get PDFFuzzy stochastic optimization has emerged as an effective approach for dealing with probabilistic and imprecise uncertainties, which makes it useful for problems when data is simultaneously impacted by vagueness and randomness. When these uncertainties involve in decision making problem where, it is required to determine the relative merits between different alternatives, we have often used the fuzzy stochastic fractional programming problem. This paper developed a new approach to derive the acceptable range of objective values for a Multi-objective fuzzy stochastic linear fractional programming problem (MOFSLFPP). In this problem, the fuzzy random variables coefficient is involved as the parameters of the objective function as well as system constraints. The proposed method constructs an expectation model based on the mean of the fuzzy random variable. For the satisfaction level of decision-makers, the level set properties of the fuzzy set are applied in the objective function. The chance-constrained programming method is utilized to transform the MOFSLFPP into its equivalent crisp form. For validation of the proposed methodology, an existing numerical has been solved, and the comparison of the proposed methodology has been discussed with the existing one. Also to demonstrate the practical application of this methodology, an inventory management problem has been discussed
Analysis study of hybrid Caputo-Atangana-Baleanu fractional pantograph system under integral boundary conditions
Get PDFThis manuscript investigates the qualitative analysis of a new hybrid fractional pantograph system involving AtanganaBaleanu-Caputo derivatives, complemented by hybrid integral boundary conditions. Dhage’s fixed point theorem is employed to investigate the existence theorem of the solutions, while uniqueness is proven by using Perov’s approach and Lipschitz’s matrix. The Hyers-Ulam (HU) stability is also demonstrated using the Lipschitz’s matrix and techniques from nonlinear analysis. Finally, illustrative example is enhanced to examine the effectiveness of the obtained results
