Accurate localization of buried water pipelines in rural areas is crucial for maintenance and leak management but is often hindered by outdated maps and the limitations of traditional geophysical methods. This study aimed to develop and validate a multi-source remote-sensing workflow, integrating UAV (unmanned aerial vehicle)-borne near-infrared (NIR) surveys, multi-temporal Sentinel-2 imagery, and historical Google Earth orthophotos to precisely map pipeline locations and establish a surface baseline for future monitoring. Each dataset was processed within a unified least-squares framework to delineate pipeline axes from surface anomalies (vegetation stress, soil discoloration, and proxies) and rigorously quantify positional uncertainty, with findings validated against RTK-GNSS (Real-Time Kinematic—Global Navigation Satellite System) surveys of an excavated trench. The combined approach yielded sub-meter accuracy (±0.3 m) with UAV data, meter-scale precision (≈±1 m) with Google Earth, and precision up to several meters (±13.0 m) with Sentinel-2, significantly improving upon inaccurate legacy maps (up to a 300 m divergence) and successfully guiding excavation to locate a pipeline segment. The methodology demonstrated seasonal variability in detection capabilities, with optimal UAV-based identification occurring during early-vegetation growth phases (NDVI, Normalized Difference Vegetation Index ≈ 0.30–0.45) and post-harvest periods. A Sentinel-2 analysis of 221 cloud-free scenes revealed persistent soil discoloration patterns spanning 15–30 m in width, while Google Earth historical imagery provided crucial bridging data with intermediate spatial and temporal resolution. Ground-truth validation confirmed the pipeline location within 0.4 m of the Google Earth-derived position. This integrated, cost-effective workflow provides a transferable methodology for enhanced pipeline mapping and establishes a vital baseline of surface signatures, enabling more effective future monitoring and proactive maintenance to detect leaks or structural failures. This methodology is particularly valuable for water utility companies, municipal infrastructure managers, consulting engineers specializing in buried utilities, and remote-sensing practitioners working in pipeline detection and monitoring applications.

Nowadays, in the complex business network system, the interaction of firms across borders is facing several challenges. Many studies in the literature also suggest numerous approaches to overcome these challenges. However, a few of the obstacles for internationalizing firms were studied and the challenges are increasing against firms’ growth opportunities cross-border. Taking this into account, the present research emphasized the roles of enterprises’ e-business adoptions of countries on cross-border firms’ internationalization by drawing from network theory and technology–organization–environment frames. By employing a fixed effect model to 365 enterprises, leaders’ attitudes of preferring technology-intensive firms, network infrastructure, risk-averting attitudes, country’s market size, multilingual services, e-government status, threats from competitors, reliable utility sources, human capital quality, costs of adoptions and telecom services enrichments, and costs of adopting different online services need to be taken into account before internationalization of born global companies.

The electrical power infrastructure of the modern world is advanced, efficient, and robust, yet power outages still occur. In addition to affecting millions of people around the world, these outage events cost billions of dollars to the global economy. In this paper, the revenue loss borne by electricity-supplying companies in the United States due to power outage events is estimated and predicted. Various factors responsible for power outages are considered in order to present an exploratory data analysis at the U.S. level, followed by the top ten affected states, which bear over 85% of the total revenue loss. The loss is computed using historic observational data of electricity usage patterns and the tariff offered by the energy suppliers. The study is supplemented with reliable and publicly available records, including electricity usage patterns, the consumer category distribution, climatological annotations, population density, socio-economic indicators and land area. Machine learning techniques are used to predict the revenue loss for future outage events, as well as to characterize the key parameters for efficient prediction and their partial dependence. The results show that the revenue loss is a function of several parameters, including residential sales, percentage of industrial customer, time-period of the year, and economic indicators. This study may help energy suppliers make risk-informed decisions, while developing revenue generation strategies as well as identifying safer investment avenues for long-term returns. Full article

Gen Z, people born in the Internet age, are entering the labour market and soon will be responsible for public administration. Such a situation creates the need to study their professional motivations and competencies. We aim to determine: (1) What are the motivating factors of Gen Z representatives? (2) What is the factor’s structure of competencies of Gen Z employees? (3) Do Gen Z’s interest in public administration result from their needs to realise the public interest? These questions are fundamental for the strategy of hiring and training newcomers. This original paper’s insights have emerged iteratively based on a systematic literature searching method and data obtained from the surveys (n = 335). Research of Polish representatives of Gen Z showed that their expectations are similar to those found in other countries. However, their responses suggest that ethical issues are not the most important for them. The presence of generation G on the labor market will generate a paradigm shift in the activity of companies and public institutions that will be the employers of these young people. Reconfiguration of the principles of human resource management is necessary so that organizations benefit from the qualities of generation Z—they gravitate towards gamified processes because of mobile-centricity; they are natives of global communication, self-learners, and self-motivators; they appreciate transparency.

The general objective of this paper was to determine how companies in the olive sector could convert the comparative advantages of olive-growing regions (e.g., culture, tradition, raw materials, knowledge, infrastructure, networks, technological centers, etc.) into competitive advantages, to internationalize, in an accelerated way, and become born global firms, contributing to economic, social, and sustainable development of regions. Thus, we analyzed four cases of exporting companies in this sector (two born global and two non-born global) in southern Spain (Jaén). We chose this province because it is the world’s leading producer of olive oil and, yet it is only the fourth largest exporter compared to the rest of Spain. For the case study, we conducted (and recorded) personal, semi-structured interviews with the founders/managers or individuals in charge of internationalization. To obtain our results, we used a data sheet that included an action protocol, we analyzed each case individually, and we employed sensemaking and pattern-matching techniques to add validity and reliability to the research. Finally, we proposed the “keys” for these companies to go international in an accelerated way, as it would increase their competitiveness, foster the creation of employment, develop networks between companies, boost investment in innovation, etc. The results indicate that it is necessary to follow market orientation, networking, and international entrepreneurship strategies, and that intellectual capital (human, organizational, relational, and technological) of companies (and, therefore, of regions) will be the means through which competitive capabilities are achieved.

The proliferation of fact-checking services is a fast-growing global phenomenon, especially in Western countries. These services are the response of journalism to disinformation, that has transformed a common internal procedure of journalistic work in the core of a business directed to the general public, also offered to the companies of mass media and social media. Literature review shows that the research on fact-checking has focused on the origin, funding, relationship with the media, procedures, and experiences related to politics and COVID-19. However, the ownership structure of the fact-checking services has been superficially analysed and the business model of these platforms has not yet been studied in detail and depth. The objective of this article is to identify and analyse the business model of the nine Spanish active fact-checking services through a documentary research of public information sources and the information that these services give about themselves. This paper explains their ownership structure and income provenance, from open information sources. The findings are that the fact-checking services that depend on media groups are no strangers to the trend of opacity usual in these groups, but in the case of fact-checking services that are born as initiatives of journalists, the trend towards transparency is, in the majority of cases, clear. However, the information provided by the Spanish fact-checking services is deficient and does not allow us to discover their business models, except in the case of Newtral and, to a certain extent, Maldita.

This research analyzes the moderation effects of Hofstede’s Cultural Dimensions (Power Distance, Uncertainty Avoidance and Indulgence) in the relationship between Ambidextrous learning and corporate sustainability in born global firms. The data were collected from exporting firms characterized by beginning international operations in the first three years and were thus classified as Born Global. A panel Dynamic Structural Equation Model (DSEM) was used to test the research hypothesis. One of the methodological contributions is the exploration of dynamic social behaviors that are difficult to study, specifically over time. Here, DSEM becomes in a data analysis technique that allows us to analyze this type of phenomena. The research results show that the relationship between Ambidextrous learning (AL) and Corporate Sustainability (CS) is positive in the short- and long-term. The cultural dimension’s Power Distance and Uncertainty Avoidance moderates the relation between (AL) and (CS) and this dimension can predict their inertia. However, while Uncertainty Avoidance has a moderating effect, it does not predict future behaviors. Published literature on the Born Global company. that includes the moderation of Hofstede’s dimensions (Power distance, Avoidance of uncertainty, and Indulgence) from a company perspective that study the relationship between Ambidextrous Learning and Corporate Sustainability is scarce.

Background: In the context of the global COVID-19 pandemic and the expansion of the more transmissible 20J/501Y.V3 (Gamma) variant of concern (VOC), mRNA vaccines have been made available in French Guiana, an overseas French territory in South America, from mid-January 2021. This study aimed to estimate the willingness to be vaccinated and the socio-demographic and motivational correlates among Health Care Workers (HCWs) in French Guiana. Methods: A cross-sectional survey was conducted from January 22 to March 26, 2021 among a sample of HCWs in French Guiana. They were asked about their willingness to get vaccinated against COVID-19 and vaccine hesitancy, vaccine uptake and vaccines attitudes. Factors associated with willingness to get vaccinated have been analyzed with ordinal logistic regression, using Stata software. Results: A total of 579 HCWs were interviewed, including 220 physicians and 200 nurses most often working in hospital (54%) or in the liberal sector (22%). Overall, 65.6% of respondents reported that they were willing or had already been vaccinated against COVID-19, while 24.3% of respondents reported that they did not want to get vaccinated against COVID-19 and 11.2% were unsure. HCWs were more willing to get vaccine if they were older, were worried about COVID-19 and were confident in the management of epidemic. Conversely, participants were less likely to have been vaccinated or willing to if they were nurses or of another non-medical profession, born in French Guiana, feared adverse effects, or if they did not trust pharmaceutical companies and management of the epidemic by authorities. Conclusion: Negative attitudes towards vaccines are a major public health concern among HCWs in French Guiana when considering the current active epidemic with Gamma VOC. General vaccine hesitancy and concerns about future side effects in particular represent important barriers. Low confidence in government and science are significant in COVID-19 vaccine refusal among non-medical staffs. Public health messaging with information on vaccine safety should be tailored to address these concerns. The specific challenges of HCWs from French Guiana must be taken into account. Full article

This study is intended to determine the effects of system management on value creation and global growth in born startups. To achieve this, a survey was empirically carried out on 300 owners in born startups with less than five years’ experience. The findings are as follows. First, entrepreneurship, operation system, and support system as sub-variables of system management have a positive effect on value creation. Second, entrepreneurship and operating system have no significant effect on global growth, but the support system has a significant effect on global growth. Third, value creation has no significant mediating effect on global growth, which means that owners’ entrepreneurship can boost value creation as a corporate systematic operation when they have globally-oriented thinking, relationships through global network organization, the expertise of business, and some level of capital. In particular, their capability and expertise can be drivers to enter early global growth companies through value creation. Consequently, for the early value creation and global growth of born startups, they should recognize that system operation and value creation-oriented corporate global experience, due to their entrepreneurship as international companies under global market orientation, are key variables affecting a global born startup, and thus reflect them in management.

The current principles of doing business differ radically from those that were applied a few years ago. Global economic crises have shown that business must have a more social character. This gave rise to the creation of management solutions that would guarantee the satisfaction of a wide range of corporate stakeholders. In this context, ideas based on social potential began to emerge. As a consequence, the concept of social business models was born, accompanied by an attempt to search for the best business models possible in order to build the appropriate configuration of their components. According to the authors, an attribute of trust may be such a component based on which effective social business models can be built. As water supply companies are social enterprises, they have become the object of scientific research in this case. The purpose of the article is to determine the position of trust in the construction and application of social business models of water supply companies. The scope of the article includes scientific research into water supply companies in the most industrial region of Poland, Upper Silesia, with the most extensive and dense water supply network in the country. In this article, the AHP (analytic hierarchy process) method was used to conduct research. The aim of the analysis was focusing on the issue of trust as a key factor in shaping the social business model of the company. In the questionnaires, respondents were asked to answer questions on the following issues: trust-based organizational behavior at the company; trust-based social capital at the company; trust-based relationships at the company; trust-based processes and activities at the company; trust-based risk at the company; and the trust-based business model at the company. The adopted logic of the scientific argument conducted indicates that trust and its place and role in the social business model of a water supply company have a significant impact on the social and economic performance of the water supply company, and as a consequence, on increased social responsibility towards stakeholders as well. Trust even stabilizes the organization and its business model; it is also a value catalyst and neutralizes the potentially negative impact of the organization on other entities gathered around it. Trust as a stabilizer can also affect the consistency and scalability of the social business model of a water supply company. Full article

Increasing environmental, social and economic problems, born by unceasing economic growth, have transformed our approach to the development concept. The 1980s saw the appearance of the sustainable development term and, during the 1990s, sustainability notion was implicitly framed as an integrated concept, frequently, termed as the ‘triple bottom line’ approach. Among several initiatives and efforts to balance our economic and societal pursuits with environmental challenges the, lately, introduced United Nations (UN) Sustainable Development Goals (SDGs) refer to a remarkable evolution, which came to strengthen and establish sustainability conception as an integrated social, economic and environmental triptych. International shipping, as the major carrier of world trade and significant contributor to environmental degradation has, definitely, a vital role to play in facilitating the UN’s sustainability venture. Although there is a great amount of legislative instruments, codes and guidance to address sustainability in shipping, though, limited research has been devoted to identify how the tanker and dry bulk maritime sector has responded to such recent cohesive attitude to sustainable maritime development. Through a quantitative research approach this empirical study aimed to investigate maritime industry’s insights and attitudes in relation to the, newly, introduced triple bottom line approach to global sustainable development. Research data were collected via a questionnaire survey conducted to 50 tanker and/or dry bulk shipping companies. Pearson’s chi-square test of independence and Spearman’s correlation coefficient measures were utilized to test our three formulated hypotheses. Findings highlighted increasing awareness and adaptation of the maritime sector to the triple bottom line approach and, subsequent, sustainability absorption under the auspices of a corporate social responsibility (CSR) business model. Introduction of sustainable development in an integrated manner appears to have influenced the extent that statutory maritime regulations occupy to the formulation of marine safety management systems. To sum up, the integrated management system model turned out to be the most rated tactic to manage sustainability and, as such, a conceptual CSR framework was proposed to facilitate such an objective.

Disaster risk reduction (DRR) is a high priority on the agenda of main stakeholders involved in sustainable development, and earth observation (EO) can provide useful, timely, and economical information in this context. This short communication outlines the European Space Agency’s (ESA) specific initiative to promote the use and uptake of satellite data in the global development community: Earth Observation for Sustainable Development (EO4SD). One activity area under EO4SD is devoted to disaster risk reduction (EO4SD DRR). Within this project, a team of European companies and institutions are tasked to develop EO services for supporting the implementation of DRR in International Financial Institutions’ (IFI) projects. Integration of satellite-borne data and ancillary data to generate insight and actionable information is thereby considered a key factor for improved decision-making. To understand and fully account for the essential user requirements (IFI and client states), engagement with technical leaders is crucial. Fit-for-purpose use of data and comprehensive capacity building eventually ensure scalability and long-term transferability. Future perspectives of EO4SD and DRR regarding mainstreaming are also highlighted. Full article
