Digital infrastructure expansion in Europe raises a spatial planning problem: early-stage screening needs to compare regional conditions while also checking whether rankings remain stable when decision priorities change. This study evaluates 24 European Nomenclature of Territorial Units for Statistics level 2 (NUTS-2) regions for geo-distributed data center development. The 2022 decision matrix uses five Eurostat criteria: information and communications technology (ICT) specialists’ share in employment, average hourly labor cost, renewable electricity share, non-household electricity price and population density. Four criteria are national intensive proxies assigned to the selected NUTS-2 regions, while population density is directly observed at the NUTS-2 level. After a log₁₀ transformation of population density and min–max normalization, we compare the weighted sum model (WSM), TOPSIS and VIKOR across four weighting scenarios. We then apply a random-weighting audit based on Stochastic Multicriteria Acceptability Analysis (SMAA) principles, using 10,000 Dirichlet weight draws, followed by a local Dirichlet sensitivity analysis around the Balanced profile. Results show that the most stable high-performing profiles are not limited to the established FLAP-D market reference. Latvija (LV00), Stockholm (SE11), Helsinki-Uusimaa (FI1B), Eesti (EE00) and Área Metropolitana de Lisboa (PT17) form the main high-performing set across stochastic rank metrics, while several mature Western metropolitan regions remain more sensitive to cost and territorial-pressure criteria. The study provides a reproducible spatial decision support framework for macro-regional screening rather than micro-siting. Full article

Generative artificial intelligence (GAI) enables students to offload cognitive tasks to an external system, yet the consequences of such cognitive offloading for the development of critical thinking—a core dimension of human intelligence—remain underexplored. Drawing upon cognitive offloading theory and distributed cognition theory, this study investigates the heterogeneity of critical thinking outcomes among Chinese university students who use GAI, focusing on how different patterns of human–AI collaboration relate to cognitive autonomy relinquishment. A questionnaire survey was administered to 353 university students across multiple provinces in China. Cluster analysis and regression analysis were employed to identify distinct user profiles and to examine predictors of critical thinking gains and cognitive autonomy. Four distinct user profiles emerged, ranging from “simple Q&A users” (25.2%) to “critical co-thinkers” (15.6%). Learning motivation was the strongest predictor of both critical thinking gains (β = 0.42) and lower cognitive autonomy relinquishment (β = −0.35). Notably, offloading depth positively predicted cognitive autonomy relinquishment (β = 0.25), revealing a paradoxical pattern: sophisticated GAI use was associated with greater dependence. A “high depth–high dependence” subgroup (25.8%) was identified, disproportionately composed of female students and Information and Communication Technology (ICT) majors. The findings challenge the assumption that deeper GAI engagement automatically yields cognitive benefits. Because all constructs were measured through self-report, the findings are interpreted as reflecting students’ perceptions of their cognitive behaviors and abilities; the methodological implications of this design are discussed in detail. Educational interventions should prioritize metacognitive training over technical skill development to ensure that cognitive offloading enhances rather than undermines critical thinking.

New information and communication technologies (ICTs) and applications of artificial intelligence (AI) have profoundly shaped our relationship with the world and with ourselves. As they are no longer merely tools or media, many scholars now describe these technologies in terms of environments. Although the concept of the digital environment has been extensively examined from a theoretical perspective, an ethics of digital environments qua environments has not yet been developed. In this paper, we advance a framework for an ethics of artificial environments, beginning with the fundamental questions that define this field of inquiry. The article develops this proposal in three steps: first, it examines the form of intrinsic value that may be attributed to digital environments; second, it considers the ways in which humans inhabit and dwell within these environments; and finally, it elaborates the metaphor of the digital garden as an ethically significant space in which responsibility is articulated through cultivation, co-dependence, and sustained care.

The quality of technology integration in K-8 science classrooms has significant implications for educational equity, particularly in minority–majority districts where teacher practice is among the strongest predictors of STEM persistence among underserved populations. This study examined the extent to which K-8 science teachers’ technology integration knowledge translated into transformative instructional practice within a large, minority–majority district in the U.S, using the frameworks of Information and communication technology (ICT)-Technological Pedagogical Content Knowledge (TPACK) and Passive, Interactive, Creative, Replacement, Amplification, Transformative (PICRAT) model. Technology integration planning knowledge was assessed using the ICT-TPACK instrument across elementary and middle school teachers. Instructional practice was rated using the PICRAT framework applied to teachers’ open-ended descriptions of their technology use. These responses also provided contextual illustration of quantitative patterns. Results indicate that while middle school teachers demonstrated significantly higher ICT-TPACK planning knowledge, this advantage primarily reinforced foundational science concepts through passive consumption rather than facilitating student agency. PICRAT analysis revealed that technology use across all grade levels was dominated by Replacement and Amplification practices, while creative and transformative uses remained nearly absent. These findings reveal a persistent knowing–doing gap in which planning knowledge did not translate into transformative enacted practice. Implications for equity-focused professional development and structural supports moving K-8 science teachers toward more transformative technology integration are discussed. Full article

The escalating frequency of extreme weather events poses severe threats to power system security, often resulting in catastrophic economic and societal consequences. As modern information and communication technologies (ICTs) integrate deeply with power grids, post-disaster communication failures and electrical faults become increasingly interdependent, complicating the restoration of distribution cyber–physical systems (CPSs). To bridge the gap where conventional Unmanned Aerial Vehicle (UAV)-enabled emergency communication ignores coordination with power system restoration, this paper proposes a coordinated recovery method featuring a two-stage UAV deployment strategy. First, a coupled cyber–physical model is established to characterize the cross-layer interaction mechanisms. On this basis, a bi-level optimization framework is developed: the upper level formulates a dynamic two-stage UAV deployment strategy to minimize the mobilization of resources, while the lower level executes network topology reconfiguration to maximize weighted load restoration, constrained by the recovered communication coverage. Simulation results on a modified IEEE 33-bus system demonstrate that the proposed method significantly enhances restoration efficiency. Compared with conventional schemes, the cumulative load loss rate is reduced by 15.75% and 2.42% across different scenarios; the two-stage UAV deployment method achieves a time reduction of 67.23%, 21.40% and 71.56%, validating the superior performance of the coordinated recovery strategy in disaster-stricken CPS.

To reduce the generation of waste electrical and electronic equipment (WEEE), or electronic waste (hereafter referred to as E-waste), within urban waste streams, extended producer responsibility (EPR) has evolved into an important framework for E-waste management and circular economy policies worldwide over the past thirty years. This policy has received increasing attention because of concerns regarding environmental pollution and resource depletion, as E-waste may contain heavy metals, such as mercury, cadmium, and lead, as well as valuable metals, including gold, silver, platinum, palladium, copper, and aluminum. In the developed East Asia region, Japan, South Korea (hereafter abbreviated as Korea), and Taiwan are renowned for their electronics industries and share similar socioeconomic and environmental characteristics, such as high population density, dependence on imported resources, and comparable levels of per capita national income. This review paper first provides the brief information on precious and valuable base metals derived from E-waste in urban waste. Furthermore, it presents a brief overview of the legal systems for urban waste management and compares urban mining from E-waste in Japan, Korea, and Taiwan. In this regard, the policies, regulations, and achievements related to urban waste management and E-waste recycling in East Asia, especially in Taiwan, are summarized and linked to increasing recycling rates for urban waste, including E-waste. Finally, the paper also examines two leading case studies in Taiwan, which focus on the recovery of precious metals from information and communication technology (ICT) products and valuable base metals from home electronic appliances, respectively.

The prompt spread of misleading information through recent information and communication technologies (ICT) admonishes social convention and credence. Developing trustworthy algorithms that can automatically identify fake content becomes increasingly difficult. We investigate a hybrid artificial intelligence (AI) strategy that integrates machine learning (ML) and deep learning (DL) to enhance fake news detection. The model’s deep learning entity evaluates confined text arrangements and inclusive text values using a Convolutional Neural Network (CNN) and Bidirectional Long Short-Term Memory (BiLSTM) with an attention layer. Conventional machine learning classifiers, mostly Support Vector Machine (SVM), Random Forest (RF), and Logistic Regression (LR), are trained synchronously employing Term Frequency–Inverse Document Frequency (TF-IDF). A simple ensemble averaging strategy is used on both machine learning and deep learning predictions. The model demonstrates strong generalization across various text types when evaluated on the LIAR dataset and a Kaggle-style fake news dataset. The combined system performs noticeably better than each of the separate models in terms of accuracy, precision, recall, F1, and AUC. Full article

The rapidly aging global population is placing immense pressure on healthcare systems, which are struggling to meet the needs of older adults. Information and communication technologies (ICTs) are considered a key driver in supporting the development of age-friendly healthcare models. This scoping review aims to map and structure the multifaceted applications of ICTs in age-friendly healthcare, focusing on their design, benefits, challenges, and implementation in different contexts. We followed the PRISMA-ScR guidelines and conducted a systematic search of five major databases (Web of Science, Scopus, PubMed, ScienceDirect, and IEEE Xplore), supplemented with backward citation chaining to improve the robustness of literature identification. The results show that ICTs can help older adults by improving their access to healthcare information, enhancing their care coordination, supporting their independent living, and personalizing their health management. Key challenges include user experience issues for older adults, data privacy and security concerns, and implementation barriers related to resources and professional support. Effective implementation of ICTs requires greater emphasis on age-centered design, robust data governance, and scalable integration with existing healthcare systems. We further propose a Technology Design–Scenario Application–Effect Evaluation (TD-SA-EE) analytical framework for ICT application in age-friendly healthcare; the framework is grounded in sociotechnical systems theory to provide explanatory insights beyond descriptive classification. This research provides insights into optimizing age-friendly healthcare through ICTs and contributes to fully leveraging ICTs in building sustainable and equitable age-friendly healthcare systems.

This study develops a bottom-up cost optimization model (DC-DECOM) to evaluate decarbonization pathways for Japan’s data center industry, targeting carbon neutrality of the information and communications technology (ICT) sector by 2040. The model represents Power Usage Effectiveness (PUE) as a dynamic function of ambient temperature and cooling technology, and integrates technology selection, regional energy supply, and carbon pricing within a single cost-minimization framework. Three scenarios are compared: a reference case (REF), a centralized carbon-neutral scenario (C-CN) that restricts new capacity to metropolitan areas, and a regional decentralization scenario (R-CN) that allows for nationwide siting. Input parameters are calibrated against data from the International Energy Agency (IEA), the Uptime Institute, Japan’s Ministry of Internal Affairs and Communications (MIC) White Papers, and the Japan Science and Technology Agency (JST). The R-CN scenario achieves the 2040 net-zero target at 18–23% lower total system cost than C-CN. The cost gap decomposes into four channels (cooling-energy reduction ∼35%, lower regional renewable procurement cost ∼30%, lower carbon cost ∼25%, and lower siting-related cost ∼10%). Sensitivity analysis identifies the carbon-price trajectory and the hardware-efficiency improvement rate as the most influential parameters; the R-CN advantage remains positive across all $\pm 1\sigma$ parameter variations and across two combined-scenario stress tests.

Despite the productivity and economic limitations imposed by environmental and climatic conditions, livestock systems play a fundamental role in preserving habitats and high-conservation-value species, while delivering a broad spectrum of ecosystem services to rural populations. Breeders need timely information to produce safe, inexpensive, environmentally, and welfare-friendly food products. Information on feeding and nutrition is of particular importance since it represents a significant percentage of animal breeding costs. Automating the collection, analysis, and use of production-related information on livestock feeding systems represents one of the central challenges facing the sector. Precision feeding systems (PFSs) have deeply changed farm management by providing new information on the health status of animals, their welfare, and nutritional requirements. PFSs encompass modern electronic and ICT-related (information and communication technologies) technologies that facilitate the electronic measurement of critical components, ensuring optimum efficiency of both resource use and animal productivity. This review analyzes the current state and potential applications of precision feeding systems for sustainable livestock production. The implementation and feasibility of PFSs have been investigated across the major animal production species and contexts. Based on the available literature, real-time monitoring and control systems can improve the production efficiency of livestock farms. However, further research is needed, as several components of PFSs are still at different stages of development and commercial readiness. Full article

This study explores the barriers that hinder the acquisition of digital skills in women with basic education, as well as their relationship with socio-communicative needs in contexts of exclusion. A validated questionnaire (α = 0.970), based on the DigCompEdu framework, was applied to a sample of 575 women in Granada (Spain). Using non-parametric analyses (Kruskal–Wallis test), significant differences were identified according to variables such as age, educational level, employment status and income. The results reveal that older women, women with low incomes, lower educational levels and unemployed women have greater difficulties in accessing, searching for information, creating content, and solving problems with ICT. However, a positive attitude towards technology was observed in all profiles, which constitutes an opportunity for intervention. It is concluded that the digital divide in women with basic training is conditioned by structural factors that generate specific socio-communicative needs. We propose the implementation of training policies with an intersectional and gender focus that favor digital equity and the active inclusion of these women in the digital society. Full article

Global warming and increasing heatwaves elevate the risk of exertional heat illnesses, particularly heatstroke, in endurance athletes and outdoor workers. This study developed and validated a wearable heatstroke warning system integrating physiological and environmental monitoring with a real-time web dashboard. The wrist- and finger-worn prototype comprised an ESP32 microcontroller and heart rate (MAX30101), skin temperature (MAX30205), ambient temperature and humidity (SHT31), and galvanic skin response (Grove-GSR v1.2) sensors with dual acoustic–visual alerts and WiFi transmission. Fifteen triathletes (18–39 years) completed 30 min of cycling in a climatic chamber: 0–15 min at 24 ± 1 °C, 70 ± 10% RH, and 16–30 min at 27 ± 1 °C, 90 ± 10% RH, with the workload rising from 40%HRmax by 10% every 10 min. Heart rate, estimated core temperature, ambient temperature, relative humidity, and GSR were recorded every 30 s and compared with standard devices using Spearman correlation (p = 0.01) and Wilcoxon signed-rank tests (p < 0.05). Heart rate, skin temperature (used a linear model to calculate core body temperature), ambient temperature, and humidity sensors showed fair–very good validity (r = 0.692, 0.995, 0.994, 0.952), while GSR was low (r = 0.298). No significant differences were observed for heart rate, skin temperature, and humidity (p > 0.05), but body temperature (p = 0.003) and GSR (p < 0.001) differed. The system showed promising validity for real-time heatstroke risk monitoring, with further refinement needed for skin temperature and GSR sensing. Full article

A strong transportation infrastructure is critical in advancing ICT trade by facilitating the efficient movement of goods and services. This efficiency enhances supply chains and attracts greater foreign direct investment, ultimately supporting technological development and boosting the economy. This article evaluates the relationship between transportation infrastructure (TI), information and communication technology trade openness (ICT trade), foreign direct investment (FDI), and economic growth (GDP) in Saudi Arabia from 1990 to 2023. Using the Autoregressive Distributed Lag (ARDL) model, we found that ICT trade has a statistically significant positive effect on long-run GDP growth. However, in the short run, ICT trade has a positive but non-significant impact on GDP growth. Additionally, the results show that TI has a statistically significant negative effect on short-run GDP growth. Moreover, the non-linear Threshold Regression model results show a threshold value for information and communication technology trade openness (ICT trade) of approximately 0.4051. Specifically, the findings indicate that increased ICT trade reduces the negative impact on economic growth beyond a certain threshold. This study is highly significant for Saudi Arabian decision-makers, as it highlights the roles of transportation infrastructure and ICT trade in attracting FDI and bolstering the economy.

This study proposes an interdisciplinary approach that integrates bioclimatology, agronomy, environmental education, and information and communication technologies (ICT) to analyze their potential to support sustainable land management in the context of climate change. The research focuses on the application of bioclimatic indices, the continentality index (Ic), the ombrothermic index (Io), and the thermicity index (It/Itc), combined with the use of a virtual herbarium as a didactic resource for interpreting ecological indicators associated with vegetation. The study was conducted using a pretest–posttest design aimed at assessing students’ self-reported understanding of ecological concepts, bioclimatology, geobotany, and the use of digital tools for learning plant species. The results show a significant improvement in students’ perceived understanding following the educational intervention, with the mean questionnaire score increasing from 21.99 (SD = 5.03) in the pretest to 31.33 (SD = 5.06) in the posttest (t(69) = 37.13, p < 0.001). The normalized gain (g = 0.42) indicates a moderate improvement in students’ self-reported comprehension of bioclimatic and ecological concepts. These findings highlight the potential of ICT to strengthen environmental education and to foster the development of competencies related to sustainable agricultural and forest land management.
