Airport management is frequently faced with a problem of assigning flights to available stands and parking positions in the most economical way that would comply with airline policies and suffer minimum changes due to any operational disruptions. This work presents a novel approach to the most common airport problem – efficient stand assignment. The described algorithm combines benefits of data-mining and metaheuristic approaches and generates qualitative solutions, aware of delay trends and airport performance perturbations. The presented work provides promising solutions from the starting moments of computation, in addition, it delivers to the airport stakeholders delay-aware stand assignment, and facilitates the estimation of risk and consequences of any operational disruptions on the slot adherence.

The global tourism industry witnesses significant challenges and changes when it comes to sustainability, changing consumer preferences and ICT developments. Against this backdrop, tourism businesses need to innovate in order to stay relevant for their markets and stakeholders. Critical tourism professionals with strong analytical skills can initiate and guide these processes of innovation in the future, and reach beyond existing blueprints and organizational frameworks. This is the idea behind Sustainability in Tourism—The Corporate Perspective (SUSCOR), a 6-week, English taught, intensive specialization course that explores how sustainable business practices can create (social) returns on investment. SUSCOR is built around a real-life consultancy assignment for a work field commissioner. Students work in international project teams to assess the client’s CSR activities in order to identify strategic improvements, design a business case, present this business case to the board of directors at the client’s head office, and conclude with a final consultancy report. SUSCOR offers students a platform to practice and develop their problem solving and consultancy skills while simultaneously getting a reality check about their future professional field. As the assignment is embedded in a series of lectures and workshops about contemporary theories about sustainable development, social responsibility and business innovation, SUSCOR links academic knowledge to the reality of today’s professional field. This chapter presents the concept and design of the course, illustrates the course week by week, and provides a number of concluding remarks and recommendations that aim to guide the further development of this type of teaching activity.

BACKGROUND: Combining increased dietary protein intake and resistance exercise training for elderly people is a promising strategy to prevent or counteract the loss of muscle mass and decrease the risk of disabilities. Using findings from controlled interventions in a real-life setting requires adaptations to the intervention and working procedures of healthcare professionals (HCPs). The aim of this study is to adapt an efficacious intervention for elderly people to a real-life setting (phase one) and test the feasibility and potential impact of this prototype intervention in practice in a pilot study (phase two).METHODS: The Intervention Mapping approach was used to guide the adaptation in phase one. Qualitative data were collected from the original researchers, target group, and HCPs, and information was used to decide whether and how specified intervention elements needed to be adapted. In phase two, a one-group pre-test post-test pilot study was conducted (n = 25 community-dwelling elderly), to elicit further improvements to the prototype intervention. The evaluation included participant questionnaires and measurements at baseline (T0) and follow-up (T1), registration forms, interviews, and focus group discussions (T1). Qualitative data for both phases were analysed using an inductive approach. Outcome measures included physical functioning, strength, body composition, and dietary intake. Change in outcomes was assessed using Wilcoxon signed-rank tests.RESULTS: The most important adaptations to the original intervention were the design of HCP training and extending the original protein supplementation with a broader nutrition programme aimed at increasing protein intake, facilitated by a dietician. Although the prototype intervention was appreciated by participants and professionals, and perceived applicable for implementation, the pilot study process evaluation resulted in further adaptations, mostly concerning recruitment, training session guidance, and the nutrition programme. Pilot study outcome measures showed significant improvements in muscle strength and functioning, but no change in lean body mass.CONCLUSION: The combined nutrition and exercise intervention was successfully adapted to the real-life setting and seems to have included the most important effective intervention elements. After adaptation of the intervention using insights from the pilot study, a larger, controlled trial should be conducted to assess cost-effectiveness.TRIAL REGISTRATION: Trial registration number: ClinicalTrials.gov NL51834.081.14 (April 22, 2015).
