Cognitive mapping and multi-criteria analysis for decision aiding: an application to the design of an electric vehicle sharing service

The paper presents a model for the design of an electric car sharing service for the city of Milano. Several options of service configurations have been analysed and evaluated according to indicators, to measure the performance of such options in respect to relevant dimensions (i.e., economic and financial costs and revenues, mobility, social benefits, environmental effects). We set up a multicriteria decision analysis, structured by means of cognitive maps. Causal networks to estimate the effects of the options have been identified and instantiated by means of simulation techniques and other qualitative and quantitative models. The focus of the paper is on the development and use of the causal maps and their integration with a multicriteria method. The use of cognitive maps allowed to capture the multiple values of the problem and the value trees of stakeholders objectives. The proposed method can be useful in general for design and planning of mobility service, especially at a strategic level

The use of competition and creativity as key-driver to promote scientific culture among students?

The pedagogical value of game generally speaking, has been extensively argued since the past by several studies of educational scientists (Fröbel, 1826; Decroly, 1921). This conception is based on the idea that young people owns great expressive and creative capabilities and that education, that often involved positive competitive interaction, is able to motivate young people to learn, involving them in knowledge process consistent with their interests and abilities. These kind of activities put at stake imagination and creativity and lead students to actively learn having fun together with their classmates. In this reality, competition, if proposed as further game element, could raise the quality participation of young people to didactical activities and enable collaborative learning processes in which everyone can give its personal contribution to the construction of knowledge seen as a great social game. Moreover, children and teens own several different languages and codes to express themselves that cannot be identified only with formal linguistic skills (oral and written) if we will not lose them (C. Edwards, L.Gandini, G. Forman, 1995)

Promotion of E-bikes for delivery of goods in European urban areas: an Italian case study

The paper presents the first results of some tasks of Pro-E-Bike, an Intelligent Energy Europe (IEE) funded project, started on March 2013 ending in February 2016. Pro-E-Bike promotes clean and energy efficient vehicles, analyses the performance of electric bicycles and electric scooters (Light Electric Vehicle, LEV) for the delivering of goods in urban areas and tests the use of these vehicles in seven European countries with twenty five companies, both delivering ones and companies that deliver their own products. Pilots will enable the demonstration of measurable effects in terms of reduction of CO2 emissions and energy savings in urban transport: related data about environmental, economic and social effects resulted by the introduction of e-bikes and e-scooters in the pilot cities will be collected. The paper will give an overlooks of the Italian pilot, that will take place in Genova, describing the subjects involved and the expected results

Behavioral Change and Social Innovation Through Reward: An Integrated Engagement System for Personal Mobility, Urban Logistics and Housing Efficiency

Abstract A significant role among soft mobility measures to influence people's mobility choices and to raise awareness is played by the provision of targeted information. The integration of user-centered design, social innovation, portable devices, and sensors may have a role in influencing people's choices and consumption patterns. The paper presents two ongoing works that investigate, design and develop tools for valuing people's positive behaviors and rewarding choices in the domain of mobility and energy. The objective of such tools is both to raise people's awareness and to engage it into a collaborative environment, in order to meet a common set of targets. The strategy adopted in both the cases is based on linking "bottom-up" with "top-down" approach, i.e. by making people to behave and to make choices coordinately with decision maker's (i.e. the Public Administration or the Administrator of the system) objectives. The first regards Opti-LOG, a project co-funded by Regione Lombardia under the Smart Cities and Communities program, which concerns last-mile delivery with low emission and zero emission vehicles. The second case regards Sharing Cities, a H2020 project that includes a pilot project in the Municipality of Milano, where the focus is on citizen engagement and behaviors in the domains of personal mobility and energy. The system, by enabling mechanisms of collaboration, sharing and human capital generation, tackles the objectives of lowering energy consumption and promoting sustainable mobility and contributes to the weaving of a more cohesive social tissue

The use of competition and creativity as key driver to promote scientific culture among students

The use of didactic games in order to promote scientific culture leads to innovative methodologies and technologies that can be very effective for the learning process of students or simply to make them more curious about critical disciplines

The importance of information flows temporal attributes for the efficient scheduling of dynamic demand responsive transport services

The operation of a demand responsive transport service usually involves the management of dynamic requests. The underlying algorithms are mainly adaptations of procedures carefully designed to solve static versions of the problem, in which all the requests are known in advance. However there is no guarantee that the effectiveness of an algorithm stays unchanged when it is manipulated to work in a dynamic environment. On the other hand, the way the input is revealed to the algorithm has a decisive role on the schedule quality. We analyze three characteristics of the information flow (percentage of real-time requests, interval between call-in and requested pickup time and length of the computational cycle time), assessing their influence on the effectiveness of the scheduling proces

A Real-time Information System for Public Transport in Case of Delays and Service Disruptions

AbstractPromoting the use of public transportation and Intelligent Transport Systems, as well as improving transit accessibility for all citizens, may help in decreasing traffic congestion and air pollution in urban areas. In general, poor information to customers is one of the main issues in public transportation services, which is an important reason for allocating substantial efforts to implement a powerful and easy to use and access information tool. This paper focuses on the design and development of a real time mobility information system for the management of unexpected events, delays and service disruptions concerning public transportation in the city of Milan. Exploiting the information on the status of urban mobility and on the location of citizens, commuters and tourists, the system is able to reschedule in real time their movements. The service proposed stems from the state of the art in the field of travel planners for public transportation, available for Milan. Peculiarly, we built a representation of the city transit based on a time-expanded graph that considers the interconnections among all the stops of the rides offered during the day. The structure distinguishes the physical stations and the get on/get off stops of each ride, representing them with two different types of nodes. Such structure allows, with regard to the main focus of the project, to model a wide range of service disruptions, much more meaningful than those possible with approaches currently proposed by transit agencies. One of the most interesting point lies in the expressive capability in describing the different disruptions: with our model it is possible, for instance, to selectively inhibit getting on and/or off at a particular station, avoid specific rides, and model temporary deviations

Development of specific PCR assays for the detection of Cryptocaryon irritans

Cryptocaryon irritans is one of the most important protozoan pathogens of marine fish, causing the “white spot” disease and posing a significant problem to marine aquaculture. In the present study, a C. irritans-specific reverse primer (S15) was designed based on the published sequence of the second internal transcribed spacer (ITS-2) of ribosomal DNA (rDNA) of C. irritans and used together with the conserved forward primer P1 to develop a specific polymerase chain reaction (PCR) assay for direct, rapid, and specific detection of C. irritans. The specificity of these primers was tested with both closely and distantly related ciliates (Pseudokeroronpsis rubra, Pseudokeroronpsis carnae, Euplotes sp. 1, Ichthyophthirius multifiliis, Pseudourostyla cristata, and Paramecium caudaium), and only C. irritans was detected and no product was amplified from any other ciliates examined in this study using the specific primer set P1-S15. The specific PCR assay was able to detect as low as 45 pg of C. irritans DNA and a nested PCR assay using two primer sets (P1/NC2, P1/S15) increased the sensitivity, allowing the detection of a single C. irritans. The species-specific PCR assays should provide useful tools for the diagnosis, prevention, and molecular epidemiological investigations of C. irritans infection in marine fish

Physiological responses of reared sea bream (Sparus aurata Linnaeus, 1758) to an Amyloodinium ocellatum outbreak

Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves that live within its ecological range. Fish mortalities are usually attributed to anoxia, associated with serious gill hyperplasia, inflammation, haemorrhage and necrosis in heavy infestations; or with osmoregulatory impairment and secondary microbial infections due to severe epithelial damage in mild infestation. However, physiological information about the host responses to A.ocellatum infestation is scarce. In this work, we analysed the proteome of gilthead sea bream (Sparus aurata) plasma and relate it with haematological and immunological indicators, in order to enlighten the different physiological responses when exposed to an A.ocellatum outbreak. Using 2D-DIGE, immunological and haematological analysis and in response to the A.ocellatum contamination we have identified several proteins associated with acute-phase response, inflammation, lipid transport, homoeostasis, and osmoregulation, wound healing, neoplasia and iron transport. Overall, this preliminary study revealed that amyloodiniosis affects some fish functional pathways as revealed by the changes in the plasma proteome of S. aurata, and that the innate immunological system is not activated in the presence of the parasite.DIVERSIAQUA, Portugal [MAR2020]Fundacao para a Ciencia e Tecnologia [SFRH/BD/118601/2016]info:eu-repo/semantics/publishedVersio
