Vacations offer a break from daily stressors but at the same time introduce challenges away from home. While the positive aspects of vacationing, especially individual benefits, are well documented, the challenges couples face and their psychological mechanisms and outcomes remain unexplored. This study investigated the effects challenges and challenge resolution might have on shared experiences and on relationship quality. We collected data from 100 romantic couples at major tourist destinations in the Netherlands in Spring 2024. Random intercept regression models showed that novelty is positively associated with positive emotions, passionate love, and feelings of connection with partner; and that challenges would take away some of these benefits. Interestingly, challenges were associated with self-expansion, a major predictor of long-term love and passion, especially when partially resolved. Positive emotions mediated some of these relationships. These findings highlight the importance and value of studying challenges and challenge resolution on vacations for relationship and experience quality.
Turbine blade cooling has been a topic of significant interest, as increasing turbine entry temperatures result in higher cooling requirements. The present numerical method divides the blade into a finite number of elements in the span and peripheral directions and solves the heat transfer fundamental equations for convection and conduction in both directions. As inputs, the span and chord gas temperature and heat transfer coefficient distributions are required. The results include high resolution temperature prediction for the blade and coolant, at all span and chord positions. The advantages of the method include the capturing of blade temperature variation in all directions, while considering the thermal diffusion due to conduction. Mach number effects to the resulted blade and coolant temperature are highlighted, as local distribution of the gas static temperature can have a dominant role. The effect of averaging the input parameters to the predicted blade temperature is discussed and finally, different values for the material conductivity are simulated and the results are analysed.

Urban planning will benefit from tools that can assess the vulnerabilityto thermal stress in urban dense cities. Detailed quick-scan heat stressmaps, as made in this study for Johannesburg, have proven valuable inthe decision-making process on this topic. It raised awareness on theurgent need to implement measures to tackle the effects of climatechange and urbanization. Awareness on heat stress has led to theimplementation of measures to mitigate the effects of climate change.As in other countries, nature-based solutions (e.g. green roofs and walls,swales, rain gardens, planting trees etc) are considered in urban areasin South Africa for various reasons. The awareness of the effect ofnature based solutions on heat stress is still low, which can be improvedby the use of heat stress maps. Some of these measures are alreadymapped on the open source web tool, Climate-scan(www.climatescan.nl) for international knowledge exchange aroundthe globe.
In an increasingly complex and rapidly changing world, traditional disciplinary approaches to the framing and resolution of social and economic problems deliver ever diminishing returns.Discussions abound, therefore, about how best to educate and prepare graduates for the fresh challenges of the 21st century.Knowledge Alliances between Higher Education Institutions (HEIs) and enterprises which aim to foster innovation, entrepreneurship, creativity, employability, knowledge exchange and/or multidisciplinary teaching and learning are therefore becoming increasingly necessary and relevant. The challenge is to determine what we should teach in the future and how it should be taught. The changing nature of contemporary society highlights that social issues are often highly complex and multifaceted.The aim of this Action is to demonstrate, through the adoption of Multi-Disciplinary Innovation (MDI) methods, how we can respond to social problems with a design-led approach which has a problem-oriented ethos, supporting positive social change and the development of international public policy discourse. It will be achieved through the establishment of a Pan-European Public Sector Innovation (ePSI) lab. It will prepare students for roles in employment by integrating education programmes into the lab’s operations and it will support agencies that have a role in responding to and developing public policy.COST action on social innovation in labs
