Improved flexibility and equity for airspace users during demand-capacity imbalance - an introduction to the user-driven prioritisation process
ATFM slot-swapping represents the first step towards the participation of airspace users (AUs) in air traffic management and airport collaborative processes. SESAR is advancing this through development of the user driven prioritisation process (UDPP) to achieve additional flexibility for AUs to adapt their operations in a more cost-efficient manner in the presence of unforeseen demand and capacity imbalances that require the application of delays to flights. The contribution of this paper is twofold: (i) to present the challenges achieved so far with respect to UDPP concepts, in particular regarding fleet delay apportionment and selective flight protection; (ii) to pave the way towards future UDPP concepts through the introduction of enhanced selective flight protection
First Report of Reticulitermes flavipes (Isoptera: Rhinotermitidae) in Italy
The first record of Reticuliterms flavipes (Kol l?r) (Isoptera: Rhinotermitidae) in Europe was in 1837, in Vienna, Austria, after infested plants im ported from the U.S. were discovered in the green house of the Sch?nbrunn Palace (Kollar 1837). In 1924, R. flavipes was found on the French Atlan tic coast and initially described as a new species, R. santonensis (Feytaud 1924). The synonymy of R. santonensis with R. flavipes was eventually confirmed by mitochondrial DNA analyses (Aus tin et al. 2002). In France, R. flavipes is currently distributed in an area extending from the Gi ronde region up to Paris and Normandy, and causes structural damage to buildings and trees (Lohou et al. 1997). During the 1930s, R. flavipes was discovered in wooden forepoles of channel construction in the steam heating district of Hamburg, Germany, where populations were sup ported by the favorable microclimate (Weidner 1937). Today, populations of R. flavipes remain es tablished in Hamburg, and cause damage to buildings and trees (Hertel & Plarre 2006). In Oct 2008, a subterranean termite infesta tion was discovered by a homeowner in a de tached house and adjacent garden situated in a residential district built in the 1970s in the out skirts of Olgiate Olona (Varese), in northern Italy. Termite workers and soldiers were observed and collected during a structural inspection in Nov 2008. Specimens are maintained in the Marini termite collection at the University of Bologna. Molecular analysis was used to determine the termite species, which were preserved in 100% ethanol prior to DNA extraction. A 684-bp region of the mitochondrial cytochrome oxidase subunit II gene and a 491-bp region of the mitochondrial 16S ribosomal RNA gene were amplified by PCR. Sequencing was performed by Macrogen Inc. (Seoul, South Korea). Closely related sequences were identified from GenBank using the BLAST network service (Altschul et al. 1990) at NCBI. For both genes, nucleotide sequences were identical in the 2 workers (GenBank Accession GU070788 and GU070789). Sequences from the Olgiate Olona house corresponded (97-100% cov erage, 100% similarity for COII sequence; 92 100% coverage, 100% similarity for 16S sequence) to GenBank sequences of R. flavipes from North America and France and of R. arenincola Goell ner (Table 1). This latter species appears to be identical to R. flavipes based on the DNA se quences obtained so far

Domino D3.1 - Architecture definition
This deliverable presents the concept of operation of Domino. It includes a description of the systems, subsystems and processes that will be taken into account in the model, as well as the general scope of the model. For each of the mechanisms suggested to be modelled in the project, the deliverable provides a set of possible operational concepts and uptake/scope to be deployed
Modus D5.1 Definition of use cases
Within the Modus project, one of the main goals is to analyse how the performance of the overall European transport system can be optimized by considering the entire door-to-door journey holistically and considering air transport within an integrated, multimodal approach. In this regard, it is essential to identify the main barriers in achieving European (air) mobility goals and how air transport can evolve by efficiently connecting information and services with other transport modes to achieve a seamless journey experience for passengers. For this particular purposes, a set of use cases is identified and defined within this deliverable D5.1
Soft power: Power of attraction or confusion?
Despite its popularity soft power remains power of confusion. The paper examines the concept, with a special focus on the nature and sources of soft power. Nye’s notion of soft power is largely ethnocentric and based on the assumption that there is a link between attractiveness and the ability to influence others in international relations. This poses two problems: Firstly, a country has many different actors. Some of them like the attraction and others don’t. Whether the attraction will lead to the ability to influence the policy of the target country depends on which groups in that country find it attractive and how much control they have on policymaking. Secondly, policymaking at the state level is far more complicated than at the personal level; and has different dynamics that emphasise the rational considerations. This leaves little room for emotional elements thus significantly reducing the effect of soft power. Given the nature of soft power being uncontrollable and unpredictable, it would be impossible to wield soft power in any organised and coordinated fashion as Nye suggested. Furthermore, the relationship between two countries is shaped by many complex factors. It is ultimately decided by the geopolitics and strategic interests of nations, in which soft power may play only a limited role. The paper also discusses the link between soft power and nation branding as both concepts are concerned with a nation’s influence on the world stage. Public diplomacy is a subset of nation branding that focuses on the political brand of a nation; whereas nation branding is about how a nation as whole to reshape the international opinions. A successful nation branding campaign will help create a more favourable and lasting image among the international audience thus further enhancing a country’s soft power
