Autonomous vehicles have the potential to fundamentally change existing transportation systems. Beyond legal concerns, these societal evolutions will critically depend on user acceptance. As an emerging mode of public transportation [7], Autonomous mobility on demand (AMoD) is of particular interest in this context. The aim of the present study is to identify the main components of acceptability (before first use) and acceptance (after first use) of AMoD, following a user experience (UX) framework. To address this goal, we conducted three workshops (N=14) involving open discussions and a ride in an experimental autonomous shuttle. Using a mixed-methods approach, we measured pre-immersion acceptability before immersing the participants in an on-demand transport scenario, and eventually measured post-immersion acceptance of AMoD. Results show that participants were reassured about safety concerns, however they perceived the AMoD experience as ineffective. Our findings highlight key factors to be taken into account when designing AMoD experiences. [less ▲]

Plusieurs recherches montrent la surperformance des entreprises situées dans les districts relativement aux entreprises situées en dehors de ces territoires. Cette surperformance est essentiellement expliquée par les logiques de réseaux développées à l’intérieur des districts et les effets de synergie opérés entre les membres de ces réseaux (Becattini, 1992). Cette réalité économique a favorisé, au début des années 2000, le développement de nouvelles formes de districts : les pôles de compétitivité. L’objectif affiché par le gouvernement français fut de redynamiser le tissu économique français dans une perspective d’innovation sur des territoires régionaux plus ou moins performants. [less ▲]

Access to official documents is a key outcome of the concept of transparency as applied to the institutions of the European Union. In the 1990s, transparency offered the promise of a cure to the “democratic deficit” from which these European institutions suffered. Key factors that underpinned progress towards greater transparency and the right of access to documents are identified as: the influence of globalization and the gradual adoption of national legislations of the various member states, the “Citizens Europe” movement, the legal evolution concerning access to environmental information, the institutional evolution of the European decision-making process, the difficulties encountered during the ratification of the Maastricht Treaty and, the accession of Sweden and Finland in 1995 to the European Union. These developments culminated with the insertion of article 255 to the Amsterdam Treaty and, under the 2001 presidency of Sweden, the adoption of Regulation (EC) No 1049/2001. Official statistics reveal, however, that the right of access to documents, produced and received by the European institutions, is rarely applied by European citizens. This right, like a working knowledge of the functioning of the European Union, remains the preserve of a small circle of professionals, usually established in Brussels. It seems that transparency and the right of access to documents does not bring the citizen closer to the European institutions and it does not solve the stated “democratic deficit”. Rather, this research finds that it has been used as an instrument in an institutional struggle to limit the power of the Council and the Commission. [less ▲]

A policy-based access control architecture com- prises Policy Enforcement Points (PEPs), which are modules that intercept subjects access requests and enforce the access decision reached by a Policy Decision Point (PDP), the module implementing the access decision logic. In applications, PEPs are generally implemented manually, which can introduce errors in policy enforcement and lead to security vulnerabilities. In this paper, we propose an approach to systematically test and validate the correct enforcement of access control policies in a given target application. More specifically, we rely on a two folded approach where a static analysis of the target application is first made to identify the sensitive accesses that could be regulated by the policy. The dynamic analysis of the application is then conducted using mutation to verify for every sensitive access whether the policy is correctly enforced. The dynamic analysis of the application also gives the exact location of the PEP to enable fixing enforcement errors detected by the analysis. The approach has been validated using a case study implementing an access control policy. [less ▲]

We explore the relationship between the characteristics of social capital, the speed of access to medical technologies and the role of gender in a private practice context. Our findings from a sample of 98 German private practitioners show that: (a) being a woman has an overall negative impact on the speed of access to medical technologies; (b) private practitioners with strong social network ties obtain quicker access to medical technologies than do those with weak ties; (c) men relying on their weak ties perform better than women who do so. In contrast, we observe that women relying on strong ties outperform their male counterparts in terms of speed of access to medical technologies. [less ▲]

Polarized neutron off-specular and grazing-incidence small-angle scattering measurements are useful methods to investigate the in-plane structure and its correlation of layered systems. Although these measurements give information on complementary and overlapping length scale, the different characteristics between them need to be taken into account when performed. In this study, the difference in the accessible length scale of the in-plane structure, which is one of the most important characteristics, was discussed using an Fe/Si multilayer together with simulations based on the distorted wave Born approximation.

3D hepatic microtissues, unlike 2D cell cultures, retain many of the in-vivo-like functionalities even after long-term cultivation. Such 3D cultures are increasingly applied to investigate liver damage due to drug exposure in toxicology. However, there is a need for thorough metabolic characterization of these microtissues for mechanistic understanding of effects on culture behaviour. We measured metabolic parameters from single human HepaRG hepatocyte spheroids online and continuously with electrochemical microsensors. A microsensor platform for lactate and oxygen was integrated in a standard 96-well plate. Electrochemical microsensors for lactate and oxygen allow fast, precise and continuous long-term measurement of metabolic parameters directly in the microwell. The demonstrated capability to precisely detect small concentration changes by single spheroids is the key to access their metabolism. Lactate levels in the culture medium starting from 50microM with production rates of 5microMh-1 were monitored and precisely quantified over three days. Parallel long-term oxygen measurements showed no oxygen depletion or hypoxic conditions in the microwell. Increased lactate production by spheroids upon suppression of the aerobic metabolism was observed. The dose-dependent decrease in lactate production caused by the addition of the hepatotoxic drug Bosentan was determined. We showed that in a toxicological application, metabolic monitoring yields quantitative, online information on cell viability, which complements and supports other methods such as microscopy. The demonstrated continuous access to 3D cell culture metabolism within a standard setup improves in vitro toxicology models in replacement strategies of animal experiments. Controlling the microenvironment of such organotypic cultures has impact in tissue engineering, cancer therapy and personalized medicine. [less ▲]
