European Airport Concessions: Retail Strategies to Improve Commercial Revenue from Leisure Travelers

Aeronautical revenue from landing and handling charges to carriers is falling significantly below 60% of total revenue and will not persist as the main source of income for airports. Airports in Europe cannot continue to rely on profits from airlines; operating companies need to improve the competitiveness through commercial income from different traveler types. The purpose of this multiple case study was to understand the elements of successful sales strategies by concessionaires (retailers) at the metropolitan airport system of Zurich and Basel in hopes of improving the nonaeronautical revenue from leisure travelers, a price-sensitive customer segment. The conceptual framework was corporate strategic planning with the underlying concept of sustainable business operations. Semistructured interviews included 9 executives and senior managers of concessions and retail operations at Zurich International and Basel EuroAirport, and covered major themes such as managing the shopping experience of passengers as well as collaboration between concessionaires, airports, and airlines. The key findings, which emerged from an inductive analysis of the data, were that the identification of personalized offerings and the inclusion of individual travelers\u27 needs are required to ensure a flexible approach by each airport and shop location throughout the terminal. The collected data contained indicators for holistic and targeted concepts by retail concessions in cooperation with airport stakeholders. Social implications include sustainable retail strategies by promoting value adding products and services, improving the passenger\u27s travel experience, and ensuring the profitability of concessionaires in a changing aviation market

Identification of common variants associated with human hippocampal and intracranial volumes

Identifying genetic variants influencing human brain structures may reveal new biological mechanisms underlying cognition and neuropsychiatric illness. The volume of the hippocampus is a biomarker of incipient Alzheimer's disease1, 2 and is reduced in schizophrenia3, major depression4 and mesial temporal lobe epilepsy5. Whereas many brain imaging phenotypes are highly heritable6, 7, identifying and replicating genetic influences has been difficult, as small effects and the high costs of magnetic resonance imaging (MRI) have led to underpowered studies. Here we report genome-wide association meta-analyses and replication for mean bilateral hippocampal, total brain and intracranial volumes from a large multinational consortium. The intergenic variant rs7294919 was associated with hippocampal volume (12q24.22; N = 21,151; P = 6.70 × 10−16) and the expression levels of the positional candidate gene TESC in brain tissue. Additionally, rs10784502, located within HMGA2, was associated with intracranial volume (12q14.3; N = 15,782; P = 1.12 × 10−12). We also identified a suggestive association with total brain volume at rs10494373 within DDR2 (1q23.3; N = 6,500; P = 5.81 × 10−7)
