School connectedness has been shown to support adolescents' academic adjustment by fostering academic performance. However, the specific association between school connectedness and attentional difficulties in class has not been previously examined, nor have the potential mediating factors underlying the broader relationship between school connectedness and academic adjustment. Positive Youth Development (PYD) has also been identified as a predictor of academic adjustment in youth. This study aimed to examine the mediating role of PYD in the relationship between school connectedness and two indicators of academic adjustment, perceived academic performance and difficulty paying attention, in a sample of Spanish students enrolled in compulsory secondary education (n = 1,036; 50.3
Featured Application Generally, for measuring soil moisture and, in particular, for the correct sizing of very low enthalpy geothermal energy facilities.Abstract Measuring soil moisture is crucial for optimizing agricultural irrigation, but also, from an energy efficiency standpoint, for the proper design of very-low-enthalpy geothermal energy (VLEGE) facilities. VLEGE represents a renewable energy resource with great potential for residential and industrial applications, as it can provide heating and cooling with high energy efficiency and minimal environmental impact. Soil moisture plays a decisive role in the thermal performance of VLEGE facilities, where small variations in water content can significantly alter the thermal conductivity of the soil and, consequently, the efficiency of their horizontal heat exchangers. This paper presents a low-cost capacitive soil moisture sensor featuring optimized interdigitated electrodes and a controlled dielectric coating that ensures mechanical and electrical stability in subsurface environments. The novelty of this work lies in the validated integration of optimized IDE design, dielectric protection, embedded capacitance acquisition, and gravimetric calibration into a low-cost soil water content measurement device for environmental, agricultural, and VLEGE applications. The developed system converts capacitance variations into direct estimates of soil water content through an integrated microcontroller-based signal-conditioning stage. The developed device is robust, reliable, and readily reproducible. Furthermore, given its low cost (around & euro;50 if manufactured manually; mass-produced it would be much cheaper) and its excellent sensitivity and precision, it is ideal for setting up continuous monitoring networks, even for domestic applications, both in VLEGE installations and in other application domains, such as agriculture and environmental monitoring, where soil moisture measurement is a crucial parameter. This work contributes to the development of more efficient and accessible solutions for harnessing geothermal energy, particularly in installations where dynamic tracking of soil moisture is essential to ensure stable long-term performance.
Recently, scholars have highlighted the function of sensory experiences as a relevant element of value creation in tourism, often referred to as "sensory marketing" or "marketing of the senses." The present article examines research on sensory marketing in tourism published between 1996 and 2025. The study analyzes theoretical contributions that investigate how sensory dimensions improve tourist experiences and help destination development. To reach this, a bibliometric analysis was conducted using VOSviewer software. These instruments enabled the identification of the most prolific institutions or authors and provided analyses of co-citation and co-word networks. Generally, this study demonstrates that sensory marketing can be a powerful instrument for improving the tourist experience and destination competitiveness.
Species distribution models (SDMs) are widely used to predict the spread of invasive species, yet their accuracy over time and the influence of climate data resolution remain unclear. Here, we examine the capacity of SDMs to predict the distribution and short-term expansion of the invasive gall wasp Dryocosmus kuriphilus, and compare the performance of locally sourced, annually resolved climate data with global climatic datasets. We modelled the annual distribution and expansion of D. kuriphilus using SDMs. Three climate datasets: regional interpolations, temporally explicit CHELSA time series, and long-term CHELSA averages, were compared to test their influence on model accuracy. Habitat suitability was estimated with GLM, MaxEnt, and Random Forest, and model performance was evaluated with the Boyce index. Temporal transferability was assessed by projecting early-year models to subsequent years and analysing accuracy patterns via multifactorial ANOVA. Model accuracy, measured with the Boyce index, improved over time, surpassing 0.7 for most datasets and algorithms. Differences among climate datasets were minor, although regional data slightly enhanced early predictions. MaxEnt consistently achieved the highest and most stable performance, while Random Forest and GLM were more variable. Models projected beyond their calibration years rapidly lost predictive power, showing limited temporal transferability. ANOVA confirmed that neither climate dataset nor algorithm significantly influenced accuracy, though MaxEnt performed best overall. SDMs are valuable tools for invasive species management when used adaptively. Accuracy improves with more occurrence data but declines when projecting future expansion, highlighting the need for regular updates. Incorporating fine-scale, temporally explicit data enhances early detection, monitoring, and rapid-response interventions. Continuously updated SDMs support timely management decisions, including invasion monitoring, prioritisation of actions, and integration of biological control or other mitigation strategies.
In social entrepreneurship research, social businesses have increasingly been cited as a proper conduit to solutions for pressing social problems to transform societies into better places. As a result, the ethics of social entrepreneurship is often assumed but not explicitly explained. In this article, we reflect on this view and offer an alternative to enrich the comprehension of ethics in this area. We draw on Ricoeur's notion of the economy of the gift, which stresses the generosity that we put in our relationships with others to evaluate the ethicality of our actions. This approach brings fresh insights to judge the ethics in the social entrepreneurship field with an integrative approach that goes beyond what is considered to serve a social mission or adopting a social governance but considering the ethics of actions in the immediacy and singularity of each relationship and situation.
