Digital extension services (DESs) play a crucial role in transforming the agri-food sector while creating the potential to enhance production towards sustainable development via ensuring resource efficiency, environmental resilience, and economic viability for smallholder farmers. However, there is less research on the availability and quality of digital advisory information to provide the foundation for the ways forward to ensure accessible and timely benefits of science-based extension and innovation for smallholder farmers. This study used a systematic review method to explore the opportunities and barriers to develop interactive DESs in developing countries (2005–2021). Features of 141 articles were summarized resulting in the identification of 13 opportunities and 21 barriers. Opportunities indicate that interactive DESs were the best source for learning and the exchange of information/ideas/experiences, useful for enhancing agricultural productivity and profitability, creating network collaboration among farmers and stakeholders, and making extension service delivery cost-effective. Barriers of interactive DESs include a lack of a two-way interaction information, lack of a centralized information network between farmers and service providers, lack of technical know-how on ICTs, poor internet connection, and lack of effective training on ICTs. However, farmers’ awareness, motivation, and readiness to use interactive DESs has increased in several countries. It is therefore a great opportunity to invest in digital platforms as a long-term intervention to boost sustainable agricultural sustainability. Full article

Job satisfaction is a critical determinant in talent acquisition and corporate value enhancement. The COVID-19 pandemic has triggered a significant increase in online-based non-face-to-face services and consumption, leading to sustained growth in ICT industry job demand. Given the ICT sector’s heavy reliance on human capital and its growing workforce demands, understanding the evolving factors of job satisfaction in this sector has become increasingly crucial. This study analyzed job satisfaction factors derived from employee reviews on an online job review platform using the Dirichlet Multinomial Regression (DMR) topic model, examining temporal changes in these factors before and after the COVID-19 pandemic. As a result, 25 distinct job satisfaction-related topics were identified, and their temporal distribution patterns were categorized into three trajectories: ascending, descending, and stable. Topics exhibiting ascending patterns included work–life balance, organizational systems, corporate culture, employee benefits, work environment, and software development practices. Conversely, factors demonstrating descending patterns encompassed annual compensation, task characteristics, supervisory relationships, employee treatment, commuting conditions, work-related stress, and welfare programs. The remaining topics maintained relatively stable patterns throughout the observation period. These findings contribute to both academic literature and industry practice by elucidating the evolutionary trends in job satisfaction determinants during the COVID-19 pandemic, thereby facilitating more informed strategic human resource management decisions in the ICT sector.

The spread of information and communication technologies (ICTs) has brought advantages and disadvantages, particularly impacting youth, who use the Internet and social media applications daily. In preadolescents’ social development, problematic social media use (PSMU) and cyberbullying (CB) are potential risk factors across several countries. PSMU is defined as the lack of regulation of social media platforms that is associated with negative outcomes in everyday life, while CB refers to using digital technology to harass, threaten, or embarrass another person. Among preadolescents, CB perpetration is frequently associated with cybervictimization (CV) experiences. The underlying mechanisms that drive this relationship have received limited attention. The aim of the cross-national comparative study, rooted in the general aggression model, is to investigate the direct and indirect effects between cyberbullying perpetration and cybervictimization, testing a model involving PSMU and moral disengagement (MD) as serial mediators in this association. A total of 895 Italian and Spanish preadolescents (M_age = 11.23, SD_age = 1.064) completed a self-report survey during school hours. Descriptive statistics were computed, and a serial mediation model was run. The results show that CV is positively associated with CB, and that PSMU and MD positively serially mediate the CV–CB link. This study’s insights suggest the need for tailored educational interventions targeting European youth, to promote more positive online social interactions and a safer digital environment.

With the advent of Industry 5.0, the electrical sector has been endowed with intelligent devices that are propelling high penetration of distributed energy microgeneration, VPP, smart buildings, and smart plants and imposing new challenges on the sector. This new environment requires a smarter network, including transforming the simple electricity customer into a “smart customer” who values the quality of energy and its rational use. The SPG (smart power grid) is the perfect solution for meeting these needs. It is crucial to understand energy use to guarantee quality of service and meet data security requirements. The use of simulations to map the behavior of complex infrastructures is the best strategy because it overcomes the limitations of traditional analytical solutions. This article presents the ICT laboratory structure developed within the Department of Electrical Engineering of the Polytechnic School of the Universidade de São Paulo (USP). It is based on an architecture that utilizes LTE/EPC wireless technology (4G, 5G, and B5G) to enable machine-to-machine communication (mMTC) between SPG elements using edge computing (MEC) resources and those of smart city platforms. We evaluate this proposal through simulations using data from real and emulated equipment and co-simulations shared by SPG laboratories at POLI-USP. Finally, we present the preliminary results of integration of the power laboratory, network simulation (ns-3), and a smart city platform (InterSCity) for validation and testing of the architecture.

Background: This systematic review will address the influence of Information and Communication Technologies (ICTs) on democratic processes and citizens’ participation, which is enabled by such tools as social media, e-voting systems, e-government initiatives, and e-participation platforms. Methods: Based on an in-depth analysis of 46 peer-reviewed articles published between 1999 and 2024, this review emphasizes how ICTs have improved democratic engagement quality, efficiency, and transparency, but highlights key challenges and research gaps. Results: From this angle, ICT tools have great potential to nurture civic engagement and good governance through transparency. Challenges persist with the ethical and social implications of surveillance technologies, security concerns about digital voting systems, and the widening digital divide disproportionately affecting marginalized populations. The current regulatory framework dealing with privacy and misinformation issues is relatively weak, and there is also a lack of understanding about ICTs’ long-term effects on democratic governance. Conclusions: This review underlines the duality of the roles played by ICT as both an enabler and a challenge to democratic processes. It calls for regulatory measures to protect privacy, fight disinformation, and reduce the digital divide. Future research in this area should focus on the long-term effects of ICTs and how they can be equitably and efficiently integrated into democratic systems, with strategies aimed at maximizing benefits while minimizing risks.

Cultural heritage significantly influences the transmission of history from the past to the present and future. The core of protecting cultural heritage is inheritance, making sure the heritages can be sustainable forever. Various ICT methods facilitate the dissemination and preservation of cultural heritage information. However, traditional ICT platforms often focus on official authority perspectives, neglecting users’ preferences for retrieving cultural heritage information. To address this, a hypothetical media platform was developed to collect people’s preferences for cultural heritage content and media types through a questionnaire, leading to the creation of a new multi-media platform. For demonstration purposes, Strijp-S, an industrial cultural heritage site in Eindhoven, the Netherlands, was used as a case study. A questionnaire was administered to test the prototype’s effectiveness and compare it with a comprehensive search engine like Google. Independent and paired-samples t-tests were conducted to analyze the results, demonstrating that the dedicated multi-media platform prototype was more effective than Google in raising awareness of Strijp-S. These findings indicate that a platform designed based on users’ preferences can enhance public awareness of cultural heritage. This approach can assist policymakers in developing platforms to promote local cultural heritage effectively. Full article

Modern ICT infrastructures, i.e., cyber-physical systems and critical infrastructures relying on interconnected IT (Information Technology)- and OT (Operational Technology)-based components and (sub-)systems, raise complex challenges in tackling security and safety issues. Nowadays, many security controls and mechanisms have been made available and exploitable to solve specific security needs, but, when dealing with very complex and multifaceted heterogeneous systems, a methodology is needed on top of the selection of each security control that will allow the designer/maintainer to drive her/his choices to build and keep the system secure as a whole, leaving the choice of the security controls to the last step of the system design/development. This paper aims at providing a comprehensive methodological approach to design and preliminarily implement an Open Platform Architecture (OPA) to secure the cyber-physical systems of critical infrastructures. Here, the Open Platform Architecture (OPA) depicts how an already existing or under-design target system (TS) can be equipped with technologies that are modern or currently under development, to monitor and timely detect possibly dangerous situations and to react in an automatic way by putting in place suitable countermeasures. A multifaceted use case (UC) that is able to show the OPA, starting from the security and safety requirements to the fully designed system, will be developed step by step to show the feasibility and the effectiveness of the proposed methodology.

This article seeks to reflect on the opportunities that mobile smartphones (MSPs) present as ICT integration tools in teaching geography. The more extensive study, underpinned by the Professional Development Framework for Digital Learning (PDFDL) in ICT integration, employed a qualitative research approach. Lensed by the Professional Development Framework for Digital Learning (PDFDL), the article used the qualitative approach to garner insights from the participants regarding using MSPs as tools to integrate ICT in geography teaching. Data collection tools included interviews, observations, and document reviews. Researchers sampled (n = 4) schools, interviewed and observed (n = 13) teachers, and interviewed (n = 10) learners and (n = 8) parents in the province of KwaZulu-Natal. Furthermore, they used a purposive sampling technique to access the participants, basing the research on the premise that MSPs promote virtual reality for an array of learners. As the findings revealed, although some participants viewed the use of MSPs as a distractor in the learning space, teachers felt compelled to heed the call to modify their teaching pedagogies, such that they integrated mobile phones fruitfully in their teaching. The findings further revealed that such a paradigm shift would benefit homeschooling and facilitate a dual teaching mode at learning institutions. Curriculum planners are responsible for helping teachers accept that uncertainty is the only certainty about the future, considering the volatility, uncertainty, complexity, and augmentation (VUCA) challenges brought on by the COVID-19 pandemic. Extended lockdown periods accelerated the use of MSPs in teaching, requiring every stakeholder in the educational space to become a life-long learner by using a range of technologies and platforms.

In recent years, the attention paid to the metaverse in the scientific world has increased; the hottest topics include system architecture and enabling technologies, as well as business, privacy, ethical, and security issues. On the other side, at the mainstream level, it is well known that the company Meta (formerly Facebook) is striving to realize its interpretation of a “social” metaverse. As Meta is a big leader of social media, it is reasonable to guess that, in the future, users will participate in a new social platform, such as that which the company is building by depicting unlimited and engaging opportunities. Regardless of Meta, we ask what the opinion of people is about this possible future scenario. A literature search of previous works about this topic has been done; the few results we found were not properly on topic and showed heterogeneous content. A survey on interpretations of the metaverse of major information and communication technologies (ICT) companies that impact the consumer world was undertaken; the results show that Meta is the most prominent company with the mission of building a ”social” metaverse worldwide. Finally, a draft of a tool for assessing the predilection of people for a “social” metaverse, based on various facets of the future social platform, is proposed. Full article

Learning and using technology in the workplace are essential for a company’s commitment to the sustainable development of its resources. Finding competent engineers who can handle information communication technologies (ICTs) is a challenge for companies. Currently, however, the ability to use these technologies is limited to technicians with specialized training, and not everyone can engage in development. Therefore, it is safe to conclude that equity in the use of technology has not yet been realized. This study aims to analyze, based on actual cases, the necessary conditions and mechanisms for people with diverse experiences and circumstances, not limited to engineers, to participate in ICT development to address human resource diversity. The use of technology such as low-code platforms (LCPs) that have recently emerged on the market has shown that nonprofessional engineers without programming training can participate in development projects. This research will be useful to managers in advancing Diversity, Equity, and Inclusion (DEI) strategies in their workplaces and contribute to organizational research regarding new trends in technology use by individuals: low codability. The findings of this study are of significant relevance to the Sustainable Development Goals (SDGs) of decent work and economic growth, as well as gender equality. Full article
