A machine learning analysis of sustainable development: the case of the Harmonic Development Index

Laszlo Gyorgy Balint Bakk Soma Simon

Publication Name: Sustainable Futures

Publication Date: 2026-06-01

Volume: 11

Issue: Unknown

Page Range: Unknown

Description:

Sustainable development requires multidimensional assessment beyond GDP, as nations similar in economic performance often diverge in environmental resilience, social equity, financial robustness, and demographic conditions. This study utilizes advanced machine learning methods on the Harmonic Development Index (H2DI), an integrative composite indicator covering economic, financial, environmental, social, demographic, and knowledge-based dimensions. Employing a Self-Organizing Map (SOM), we identify topology-preserving clusters, visualizing nuanced country proximities and sustainability trade-offs beyond traditional linear models. Complementarily, a Bayesian network uncovers conditional dependencies among sustainability pillars, highlighting critical pathways influencing national development trajectories. Our approach addresses common limitations of PCA and k-means methods by capturing nonlinearities and providing probabilistic insights into sustainability dynamics. Results reveal consistent patterns, robust economic and financial sustainability correlate positively with social resilience and knowledge capacity but inversely with demographic vitality. Temporal robustness checks from 2005 to 2023 affirm stability of these relationships despite global shocks, validating the framework’s applicability for sustainable policy guidance.

How do European seniors perceive and implement the postulates of sustainable tourism?

Gagan Deep Sharma Klaudia Przybysz Agnieszka Stanimir Elżbieta Roszko-Wójtowicz

Publication Name: Equilibrium Quarterly Journal of Economics and Economic Policy

Publication Date: 2023-01-01

Volume: 18

Issue: 4

Page Range: 1217-1249

Description:

Research background:Tourism is one of the fastest-growing sectors of the economy, thus the implementation of sustainable solutions in tourism ought to be a worldwide adopted requirement. Tourists should seek to pursue sustainable development goals during their travels. Given the aging population, it is important to encourage seniors to practice sustainable tourism and tailor offerings to their needs. Purpose of the article: Our study aims to identify the readiness of seniors within the European Union to travel in line with the sustainable development goals. Methods: Representative data from Flash Eurobarometer 499 were used in the study presented in the article. Correspondence analysis, which is a multidimensional statistical method that facilitates the search for relationships between multiple characteristics of respondents, was used in the course of our study. Findings & value added: We conclude that the offer of future tourist solutions must be diverse, because the perception of tourism is very different among seniors with varying ages, genders, levels of education, and places of residence. Only small groups of seniors are not ready to adopt sustainable tourism, but many European tourists intend to continue using sustainable solutions and introduce new ones into their tourism. The greatest determination to apply sustainable solutions was observed among German seniors, especially in the use of green transportation.

Description:

The Covid 19 pandemic led to major changes at the individual, organisational and institutional levels of policy, productive functions, and organising. During Covid 19 morbidity, public institutions enforced social isolation, mandatory self-isolation, quarantines, and administrative regulatory lockdowns, which led to a movement away from the physical, material world and into an all-consuming digital universe. With growing interest in work-from-home (WFH) opportunities, this article provides an integrative review of 107 papers. It comprises the bibliometric analysis and manual review of the articles, on the basis of which we present an elaborative discussion and agenda for future research. According to the analysis, WFH looks a tad of a double-edged sword in that it may have major but unintended repercussions for institutions, and organizations as well as hidden, positive as well as negative consequences for individuals/employees. One of the significant insight from our analysis was the absence of HR function's strategic or operational input or oversight during corporate WFH strategies. We suggest several theoretical frameworks for further developing, theorizing, and empirically testing various aspects of WFH. Further, we recognise that WFH is becoming increasingly visible as a result of the pandemic scenario and significant technical advancements, which must be reflected in the research. Finally, because WFH represents a significant disruption in how organizations produce work and manage it, we propose employee and managerial consequences as future research agendas.

Receptiveness to flexible employment at Hungarian SMEs

Ákos Essosy Tamás Vinkóczi

Publication Name: Deturope

Publication Date: 2018-01-01

Volume: 10

Issue: 1

Page Range: 116-130

Description:

Nowadays, only companies that are adaptable and flexible in their structure and processes can survive. The basis for a motivated company aiming for peak performance is organisational innovation. Hungary is one of the less innovative countries in Europe. Only organisations that can integrate new solutions smoothly into their everyday operations will remain truly competitive. The Government of Hungary, in its Partnership Agreement with the European Union, set out the goals for improving and supporting the adaptability of enterprises, the promotion of flexible and family-friendly workplace practices and services, and the employment of women with young children. The aim of this study is to demonstrate, through a Hungarian example, the receptiveness of Hungarian small and medium-sized enterprises to flexible forms of employment. The effect of flexible employment on economic adaptability and competitiveness through workforce efficiency and retention is examined. Its aim is the raise the awareness of options to increase employment among Hungarian SME managers.

Speaking up with passion: Voice, leadership, and helping behavior in public organizations

Muhammad Usman Rudresh Pandey Norah Albishri Attila Kurucz Muhammad Usman Yaqin Li

Publication Name: Acta Psychologica

Publication Date: 2026-06-01

Volume: 266

Issue: Unknown

Page Range: Unknown

Description:

Healthcare delivery depends not only on technical expertise but also on the willingness of clinicians to speak up and to support one another in demanding environments. Drawing on Self-Determination Theory, this study explores how prosocial voice fosters helping behavior through the energizing role of work passion, and how ethical leadership shapes this process. Using a three-wave, multi-source design, we obtained 306 matched employee–leader dyads from public hospitals. Structural equation modeling demonstrated that prosocial voice enhanced work passion, which in turn predicted helping behavior. Mediation analysis confirmed the indirect effect, while moderation results revealed that ethical leadership amplified the passion–helping relationship, producing a significant conditional indirect effect. These findings extend theoretical work by positioning passion as a motivational mechanism that explains how voice translates into prosocial outcomes, and by showing that ethical leadership provides the contextual support necessary for this process. These results provide practical guidance for strengthening supportive climates and leadership practices that enable clinicians' discretionary contributions.

Trend Environmental Implications in Pet Food Industry: Focusing on Sustainability Issues

Veronika Keller Balázs Répási

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Volume: 114

Issue: Unknown

Page Range: 727-732

Description:

In recent years, many of the 150 pet food companies currently producing pet food in Europe have started to focus on the ethical and local sourcing of raw materials, but there is still a lack of optimisation of the production processes and sustainable sourcing of raw materials. The aim of this research is to describe the steps already taken by pet food manufacturers towards sustainability and to analyse future plans and objectives of the industry in relation to food overproduction and unnecessary waste. The Delphi method was used with a team of experts from two major international European pet food companies to gain insights to identify current aspects and also where we can see room for development. The research shows that there is a huge potential in recycled human food waste used as pet food raw material, while there are currently efforts on packaging and more effective energy consumption. Moving to insect-based pet food could be an even better approach to increase the level of sustainability. The pet food market is becoming increasingly important as a result of economic development and modern social standards, and it is particularly important to pay attention to these aspects related to the production of pet food even more.

The Impact of Shoe Heel-Toe Drop on Plantar Pressure During the Third Trimester of Pregnancy

Yaodong Gu Gusztáv Fekete András Kovács Siqin Shen Zixiang Gao Yuqi He Zhenghui Lu Xin Li

Publication Name: Advances in Transdisciplinary Engineering

Publication Date: 2024-01-01

Volume: 59

Issue: Unknown

Page Range: 509-514

Description:

Pregnancy induces various physiological adaptations to accommodate the growing fetus. Pregnant women commonly experience changes in gait, balance, and center of gravity, which may increase the risk of falls. This study investigates the effects of negative heel shoes on plantar pressure distribution during walking in third-trimester pregnant women. Twelve healthy primigravidas participated, wearing both flat shoes and negative heel shoes while walking. Plantar pressure data were collected using the Pedar-X® insole system. Results revealed that negative heel shoes significantly reduced maximum force in the medial forefoot regions compared to flat shoes, and the force-time integral only significantly decreased in the medial forefoot region. Wearing negative-heeled shoes resulted in an increase in peak force in the hallux region. The study suggests that modifying heel-toe drop in shoes can effectively mitigate plantar pressure during third-trimester pregnancy, reducing the risk of forefoot discomfort and potential injuries. Negative heel shoes could be beneficial for pregnant women, offering a solution to alleviate forefoot pressure and promote foot blood circulation during walking. However, further optimization is needed in the hallux region for negative heel shoes.

Perception Accuracy of a Multi-Channel Tactile Feedback System for Assistive Technology

Gyorgy Wersenyi

Publication Name: Sensors

Publication Date: 2022-11-01

Volume: 22

Issue: 22

Page Range: Unknown

Description:

Assistive technology uses multi-modal feedback devices, focusing on the visual, auditory, and haptic modalities. Tactile devices provide additional information via touch sense. Perception accuracy of vibrations depends on the spectral and temporal attributes of the signal, as well as on the body parts they are attached to. The widespread use of AR/VR devices, wearables, and gaming interfaces requires information about the usability of feedback devices. This paper presents results of an experiment using an 8-channel tactile feedback system with vibrators placed on the wrists, arms, ankles, and forehead. Different vibration patterns were designed and presented using sinusoidal frequency bursts on 2, 4, and 8 channels. In total, 27 subjects reported their sensation formally and informally on questionnaires. Results indicate that 2 and 4 channels could be used simultaneously with high accuracy, and the transducers’ optimal placement (best sensitivity) is on the wrists, followed by the ankles. Arm and head positions were inferior and generally inadequate for signal presentation. For optimal performance, signal length should exceed 500 ms. Furthermore, the amplitude level and temporal pattern of the presented signals have to be used for carrying information rather than the frequency of the vibration.
