CHARACTERISTICS OF CONSUMER SEGMENTS BASED ON PERCEPTIONS OF THE IMPACT OF DIGITALISATION
Publication Name: Decision Making Applications in Management and Engineering
Publication Date: 2023-01-01
Volume: 6
Issue: 2
Page Range: 975-993
Description:
The focus of our research was to examine consumer perceptions of attitudes towards digitalisation. The perception of digitalisation was also analysed from a generation-specific perspective, given that the difference in values between generations is reflected in the perception of consumer trends, including the trend towards digitalisation. The primary data presented in this study are the results of a quantitative data collection was carried out among Hungarian consumers using an arbitrary sampling procedure. A pre-tested, standardised online questionnaire survey was used, which resulted in 3, 515 evaluable questionnaires. Descriptive statistics, bivariate and multivariate analyses were used to process the quantitative results and test the hypotheses. As a result of the study, we were able to characterise three significantly distinguishable target groups using a K-means clustering procedure: the group of"consumers sceptical about digitalisation", the segment of"Accepting consumers who feel the differentiating effects of digitalisation", and The 'positive digital consumer'. We have been able to demonstrate that the perception of digitalisation can be used as a segmentation criterion, and we can also statistically demonstrate that the segments according to the perception of digitalisation carry generation-specific elements. In our opinion the results may help to increase consumer acceptance of digitalisation processes and related technologies. A limitation of the research is that, the results are valid for the population under consideration, cannot be considered representative. We believe that characterising the individual segments can help to differentiate the education process according to the awareness and attitudes of each consumer.

Government subsidies, carbon quota prices, and spillover effects of carbon emissions: Insights from the EU carbon market
Publication Name: Geoscience Frontiers
Publication Date: 2026-09-01
Volume: 17
Issue: 5
Page Range: Unknown
Description:
This paper examines the dynamics of carbon quota pricing and emissions under government subsidies in the EU carbon market. The study reveals three core findings. First, carbon emissions, carbon subsidies, and carbon quota prices exhibit strong interconnectedness with pronounced seasonality, and spillover effects intensify during exogenous shocks, particularly at short-term frequencies within one to five days. Second, Germany consistently serves as the primary source of spillover effects, reflecting its energy-intensive industrial structure and dominant position in the EU Emissions Trading System, while carbon subsidies function as information receivers in the short term but maintain stable roles in the medium to long term under the EU's sustained climate commitments. Third, the COVID-19 pandemic fundamentally altered spillover patterns, with the EU industrial sector transitioning from a net transmitter to a net recipient of spillovers and carbon quota prices shifting to net recipients during the shock. These findings are derived from a stochastic differential game model that captures strategic interactions between governments and enterprises under exogenous shocks, combined with TVP-VAR spillover analysis that quantifies dynamic connectedness across time and frequency domains. The results enhance the understanding of carbon market mechanisms under policy interventions and external disturbances, offering insights for the development of more efficient and resilient carbon trading systems.

SMART CITY INDICATORS AND THE CONCEPTUAL PROBLEMS OF MEASURING SMART CITIES
Publication Name: Deturope
Publication Date: 2024-01-01
Volume: 16
Issue: 3
Page Range: 172-184
Description:
As the popularity of smart city research is increasing, the measurement of smartness became also a popular research topic. This is in accordance with the demand of the planners and project financing institutions for the success indicators, and with the observable tendency of new indicators for describing the settlements from the point of view of the quality of life, liveability, creativity, environment, social capital, development and many other fashionable research aspects of modern urban societies. Analyses through such indicators run the risk of taking a mechanistic, technocratic, superficial approach to complex urban systems, ignoring the complex causal relationships between urban subsystems and the interpretative and statistical uncertainties behind the indicators. Moreover, these composite or complex indicators merge very different basic indicators, often with low data quality and validity. This paper focuses on the uncertainties of smart city indicators, which are often used to form composite indicators that moreover form the basis for comparisons of smartness of cities. The transformation of a multi-indicator system into a one-dimensional metric scale is a highly questionable practice. Composite indicators, despite their popularity, are methodologically and conceptually highly problematic analytical tools for researchers and normative targets for policy makers.

Publication Name: Applied Vegetation Science
Publication Date: 2022-01-01
Volume: 25
Issue: 1
Page Range: Unknown
Description:
Questions: Two scientific disciplines, vegetation science and weed science, study arable weed vegetation, which has seen a strong diversity decrease in Europe over the last decades. We compared two collections of plot-based vegetation records originating from these two disciplines. The aim was to check the suitability of the collections for joint analysis and for addressing research questions from the opposing domains. We asked: are these collections complementary? If so, how can they be used for joint analysis?. Location: Europe. Methods: We compared 13 311 phytosociological relevés and 13 328 records from weed science, concerning both data collection properties and the recorded species richness. To deal with bias in the data, we also analysed different subsets (i.e., crops, geographical regions, organic vs conventional fields, center vs edge plots). Results: Records from vegetation science have an average species number of 19.0 ± 10.4. Metadata on survey methodology or agronomic practices are rare in this collection. Records from weed science have an average species number of 8.5 ± 6.4. They are accompanied by extensive methodological information. Vegetation science records and the weed science records taken at field edges or from organic fields have similar species numbers. The collections cover different parts of Europe but the results are consistent in six geographical subsets and the overall data set. The difference in species numbers may be caused by differences in methodology between the disciplines, i.e., plot positioning within fields, plot sizes, or survey timing. Conclusion: This comparison of arable weed data that were originally sampled with a different purpose represents a new effort in connecting research between vegetation scientists and weed scientists. Both collections show different aspects of weed vegetation, which means the joint use of the data is valuable as it can contribute to a more complete picture of weed species diversity in European arable landscapes.

On wavelet based modeling of radio frequency circuits, parts and electromagnetic fiels
Publication Name: 2010 11th International Workshop on Symbolic and Numerical Methods Modeling and Applications to Circuit Design Sm2acd 2010
Publication Date: 2010-12-01
Volume: Unknown
Issue: Unknown
Page Range: Unknown
Description:
Multiresolution or wavelet analysis is widely used in advanced data compression algorithms, and some approaches applied this technique in describing electromagnetic fields. The main goal of the application of MRA is its flexibility, i.e., since the details of the electromagnetic field are not distributed equally over different parts of the system, thus locally different resolution level can be applied. Wavelet based adaptive solution possibilities of differential equations of electromagnetic field are investigated in the followings. The adaptivity of the method means in this case, that the refinement level of the solution can be increased locally, if the accuracy needs it, during the calculations. ©2010 IEEE.

Exploring N-best solution space for heat integrated hydrogen regeneration network using sequential graph-theoretic approach
Publication Name: International Journal of Hydrogen Energy
Publication Date: 2023-02-12
Volume: 48
Issue: 13
Page Range: 4943-4959
Description:
To achieve the ever-stringent sustainable goals, this paper aims to synthesize a heat integrated hydrogen regeneration network (HIHRN) using a graph-theoretic-based sequential method. Firstly, the optimal and near-optimal structures for a hydrogen regeneration networks (HRN) are determined using P-graph model with consideration of both impurity and pressure constraints. These networks are then used as inputs in P-HENS software to generate a list of optimal and near-optimal heat exchanger network (HEN) structures. An eight source and sink problem is used to demonstrate the effectiveness of the proposed method. There are 199,677 feasible HIHRN structures identified, while the 6 near-optimal solutions which are within 0.05% tolerance of the optimal network cost (i.e., less than 33.04 M$/y) are presented together with the top four HEN designs that can offer comparable costs (∼115,500 $/y). In addition, the impacts of pressure swing adsorber (PSA) pressure drop consideration and minimum temperature difference on the optimal design are also presented.

Motivation and organisational culture from the perspective of SME employees – a case study at the time of COVID-19 pandemic
Publication Name: International Journal of Services Economics and Management
Publication Date: 2024-01-15
Volume: 15
Issue: 1
Page Range: 34-50
Description:
The aim of the research is to investigate the relationship between motivation and organisational culture from the viewpont of employees working at SMEs in Slovakia. The study examines all of this during the COVID-19 period, which took a heavy toll on individuals’ social and organisational relationships as well. To investigate this, first the overlaps between the two areas were indentified. When exploring the theoretical part, the authors faced with the problem that the influence of motivation and organisational culture was usually examined together, and not on each other. A questionnaire survey was conducted, to which 581 valuable responses were received. Based on the results, it was proven that the wider the range of motivation tools used, the more positive the employees evaluate the organisational culture. All of this is worth considering for companies that would like to build a suitable organisational culture in their company.

Exploring the perceptions of athletes and DCOs on the remote sampling procedure in anti-doping testing: shifting control to burden
Publication Name: Frontiers in Sports and Active Living
Publication Date: 2026-06-04
Volume: 8
Issue: Unknown
Page Range: Unknown
Description:
Introduction – The approach of remotely collecting anti-doping samples from athletes by utilizing a Remote Sampling System (RSS) presents a technological innovation in anti-doping work, offering a potential solution to the logistical limitations of traditional in-person testing. Even though the implementation decision obliges Anti-Doping Organizations (ADOs), successful implementation hinges on whether athletes as the key stakeholders of anti-doping work perceive an RSS as legitimate. Furthermore, the perceptions of DCOs who are the key users operating an RSS and having to adapt to new sample collection procedures are largely unexplored. This study adopted an exploratory qualitative design to investigate the perceptions of athletes and DCOs. Methods – We conducted semi-structured interviews with 16 elite athletes and 22 professional DCOs. Data were analyzed using template analysis to identify their key themes and considerations associated with procedural steps of remote sampling applied in anti-doping testing. Results – Our findings reveal challenges in user-system integration, which we conceptualize as a shift from DCO control to athlete burden. For athletes, the transfer of specific sample-handling responsibilities inherent to the remote sampling procedure is perceived as an unjust burden of personal risk, logistical effort, and procedural anxiety. Key concerns include the management of test kits and the liabilities associated with taking responsibility for unobserved sample shipment. Conversely, DCOs interpret this transfer as a critical loss of control over procedural integrity and professional oversight, focusing on the inability to uphold an unbroken chain of custody. Discussion – The study concludes that RSS implementation is not merely a technological challenge but one of trust management that must consider user perceptions and concerns on how remote sampling can be designed as a legitimate procedure of anti-doping work. It must reconcile the shift from control to burden by simultaneously mitigating the athletes' burden while empowering DCOs with reliable tools, enabling them in their role as guarantors of anti-doping testing's procedural integrity. These insights provide actionable recommendations for anti-doping organizations to pilot new remote sampling protocols that are not only efficient but also perceived as legitimate, trustworthy, and effective.
