This article discusses the use of social media by different generations in destination marketing from a sustainable tourism perspective. In the light of the global COVID-19 pandemic, intensive marketing efforts and strategies to bring back sustainable tourism will soon become important. Social media (SM) can significantly support the promotion of destinations by guaranteeing an appropriate number and type of tourists. The article examines the frequency of using social media by different generations and the scope of their use in planning a tourist trip. The research was conducted in Poland on a sample of 397 respondents representing the group of Baby Boomers (BB), as well as Generations X, Y, and Z. The results of the research showed that the frequency of using SM decreases with age. The differences between the generations are visible in such behaviours as using SM to check opinions about tourist places, recommending a holiday with positive opinions and comments in SM, as well as resigning from a holiday based on negative opinions and comments.

The literature and practitioners both emphasise the need to involve universities in the promotion and implementation of SDGs. On the other hand, the lack of practical solutions to include SDGs in university activity is constantly emphasised. The objective of the article is to investigate how project‐based learning innovations used in student education affect the achievement of sustainable development goals. We analyse whether innovative project based–learning projects at a leading technology university in Poland pursued from 2018 to 2021 contribute to achieving sustainable development goals, and we study the matter of interdisciplinarity of the project teams. To this end, we employ a qualitative content analysis of reports for 108 projects that involved 324 researchers, 607 students, and 233 experts from the university's business environment. The categorical data yielded by the analysis are analysed with quantitative methods: frequency analysis, correspondence analysis, and data visualisation. The analyses demonstrated that the most commonly pursued sustainable development goals were: SDG 9: Industry Innovation and Infrastructure, SDG 3: Good Health and Well‐Being, and SDG 12: Responsible Production and Construction. Biomedical Engineering experts pursued projects dedicated to SDG 3: Good Health and Well‐Being, while Automation and Robotics specialists focused on SDGs 9: Industry Innovation and Infrastructure and SDG 11: Sustainable Cities and Communities. The primary sustainable development goal for Environmental Engineering teams was SDG 12: Responsible Consumption and Production followed by SDG 6: Clean Water and Sanitation and 7: Affordable and Clean Energy. The most common interdisciplinarity in the teams was of the second type: interdisciplinarity bringing together experts from two research areas. The article presents the results of research on the process of promoting sustainable development through project‐based learning implemented under an interdisciplinary collaboration of teams of university staff, students, and experts from businesses associated with the university. The results contribute to the academic debate on the ability of universities to teach, implement, and promote sustainable development and its goals.

The open data (OD) performance expectancy is a critical factor for the user technology acceptance models for future implementation OD in Industry 4.0, and to have an impact in area of Society 5.0. The purpose of this article is identifying trends and key words (leading terms) in promoting ODs for their use in Industry 4.0 and Society 5.0. We are also looking for leaders in Europe in promoting the use of OD in the context of Industry 4.0 and Society 5.0. The research methodology includes methods such as: analyses based on text mining, visualization techniques, and multidimensional cluster analyses with correlation analyses. The dataset covered 288 digital products and services based on OD. The timeframe covers the period January 2018–January 2020, and the research focuses on European issues. The research is focused on texts promoting the digital OD products and services, with the most popular being applications, websites and platforms. The main direction in presenting the benefits of their use is related to promoting them as tools to provide real time information on public issues, primarily in areas such as transport, education, culture and sport, economics and finance and health. The main types of OD are geodata and those specified as national and local. Additionally, the geographical area in Europe-dominating countries, and the key terms promoting product and services in context of OD performance expectancy in Western Europe, Northern Europe, Southern Europe and Eastern Europe, were found.

In the light of the COVID-19 pandemic, it is crucial to manage tourist destinations to allow the recovery of tourism on the one hand and reduce its negative impact on the environment and the local community on the other. Information provided via social media (SM) by both residents and tourists can help restart tourism. This paper identifies ways of sharing travel experiences by tourists on social media. The research was conducted in Poland on a sample of 271 respondents from each generation using questionnaires. Results showed that the way tourists use SM during and after their trip differs by generation and gender what could be used in promoting responsible behaviour for sustainable tourism. Differences between generations can be observed in behaviours such as ongoing planning the trip, obtaining information about the place to stay, keeping a photo album for friends, and writing reviews. Moreover, more often than men, women use SM to obtain information about the place of stay and share their impressions of the trip by sending MMS or emails. Tracking tourists’ travel behaviour on social media will allow city managers to gather information and respond to their needs and expectations and ensure effective urban management and city promotion.

This article attempts to evaluate the My Electricity program concerning increasing renewable energy production in photovoltaic (PV) prosumer sources (PV micro-installations) in Poland. The assessment is made from the perspective of beneficiaries, business, and local community. One may also find an answer to the question of how this program should be modified so that it continues to support the development of PV systems in Poland. Moreover, how Poles assess the PV technology, in terms of the safety of its users and its impact on the environment, is studied. For this purpose, there was exploratory, qualitative, and quantitative research conducted. Twelve case studies were used as well as online questionnaires conducted on prosumers who used the My Electricity program to install PV micro-installations (57 respondents). By means of interviews, there was a confrontation of their point of view with the opinions of seven skeptics of such installations. Moreover, five experts from the energy industry and politicians involved in the transformation of the energy system were interviewed in order to balance the enthusiastic opinions of prosumers and the skeptical views of objectors to home PV systems. The results of our research indicate that the program is rated very well by enthusiasts of PV systems, although they emphasize the high investment costs and the lack of solutions supporting energy storage. Experts point out that the power grid in Poland is not prepared for such an immediate increase in prosumer PV systems, and they suggest more care in solving this problem.

The energy transition that Poland is facing directs investment and research efforts towards renewable energy sources (RES). This topic has gained importance due to environmental and climate reasons and, recently, the ongoing military conflict between Russia and Ukraine. All these issues affect the availability and prices of fossil fuels, on which electricity production in Poland currently depends. Therefore, to change the current state of affairs, it is necessary to turn to other sources of energy, including RES. Particularly high hopes are placed on prosumer photovoltaic (PV) technology. Therefore, it becomes important to study the factors of acceptance of this technology among the Polish society. The aim of this paper is to answer two research questions: (1) what factors shape intentions to invest in prosumer PV technology and (2) what factors shape attitudes towards this technology. The research was conducted using a questionnaire on a sample of 430 people. Data analysis was performed using structural equation modeling. The results indicate that intentions are mainly shaped by attitudes towards PV technology and, to a small extent, by the media promotion of this technology. On the other hand, the factors shaping attitudes towards prosumer PV technology are environmental, economic, and those related to the perceived ease of use of PV technology. Social factors, in the light of the research conducted, do not influence attitudes towards the technology under study.
