Infrastructural Requirements and Regulatory Challenges of a Sustainable Urban Air Mobility Ecosystem

The United Nations has long put on the discussion agenda the sustainability challenges of urbanization, which have both direct and indirect effects on future regulation strategies. Undoubtedly, most initiatives target better quality of life, improved access to services & goods and environment protection. As commercial aerial urban transportation may become a feasible research goal in the near future, the connection possibilities between cities and regions scale up. It is expected that the growing number of vertical takeoff & landing vehicles used for passenger and goods transportation will change the infrastructure of the cities, and will have a significant effect on the cityscapes as well. In addition to the widely discussed regulatory and safety issues, the introduction of elevated traffic also raises environmental concerns, which influences the existing and required service and control infrastructure, and thus significantly affects sustainability. This paper provides narrated overview of the most common aspects of safety, licensing and regulations for passenger vertical takeoff & landing vehicles, and highlights the most important aspects of infrastructure planning, design and operation, which should be taken into account to maintain and efficiently operate this new way of transportation, leading to a sustainable urban air mobility ecosystem

Tecnica narrativa na ficcao butanica pos modernista Uma analise narratologica de "Selected Novels" de J. Fowles e P. Ackroyd

Because of my long-term fascination with Form in experimental fictional writing, in the ensuing study I propose a detailed examination of Narrative Technique such as found in the fictional work of John Fowles (1926) and Peter Ackroyd (1949), two key figures of the post modernist British literary scene; the former seen as a representative of the older generation of the 1960s, the latter as one of the most promising novelists of the younger generation of the 1980s. For my present analysis a selection of four narratives has been effectuated. Thus, having taken into account the preponderant significance of Fowles's work within British Post modernism, my choice fell on three of his novels, The Collector, from the early sixties; The French Lieutenant's Woman, from the late sixties, early seventies; A Maggot, from the mid-eighties; and on one of Ackroyd's novels, Hawks moor, from the mid-eighties. Fowles's first published fictional piece, The Collector, was chosen because in spite of what may seem a more "realistic" form I consider that many of the narrative features observed in this early text already point to more innovative, intricate narrative devices that will be further exploited in his succeeding novels. Considering that the French Lieutenant's Woman is a remarkable narrative, that it has become the post modernist British novel "par excellence", and has by now reached the status of canonical text within post modernism, my second choice was easy to make. The third narrative selected, A Maggot, the author's latest novel, is in my opinion not only Fowles's most political but also, as I hope to show, his most experimental text to date. My fourth and final choice fell on Ackroyd's Hawks moor, a historiographic meta fiction that, like Fowles's two previous texts, offers the reader a powerful reconstruction of the past in permanent confrontation with the present. As I want to look at the above-referred narratives fundamentally from a formal perspective and proceed to a detailed examination of the narrative technique employed by Fowles and Ackroyd in order to better understand the nature of post modernist fictional writing, I have selected the discipline of..Available from Fundacao para a Ciencia e a Tecnologia, Servico de Informacao e Documentacao, Av.
