Quanti sono i disoccupati? Misurare il non lavoro in tempo di crisi. Un percorso di analisi dagli anni Trenta a oggi
2019
This chapter seeks to explore the complex interaction between statistical devices, socio-economic processes and political practice with reference to the problem of unemployment in twentieth-century Italy, comparing three moments of economic crisis in which the lack of work assumed particular relevance in the public debate and in the life of workers (the 1930s, the 1970s and the last recession that began in 2007), focusing on the problems related to the measurement of work and non-work.
The French Communist Party and the CGTU in the department of Pas-de-Calais during the interwar period
2023
Rural department, bordered by a coastline, formerly industrialized and urbanized, the department of Pas-de-Calais was a bastion of the Socialist Party and the trade union movement before the First World War. The birth of the SFIC Communist Party in December 1920 and the union split that affected the CGT divided the labor movement. Our work is interested in the construction, the evolutions and the anchoring in a territory of an original political movement and its union relays during the years of the interwar period.It is about questioning the specificity of a political party and a trade union organization, about the links they have established between them, about the margin of autonomy they …
Thermal Design of Refridgerated Hexapole 18 GHZ ECRIS HIISI
2014
A project is underway for constructing a new 18 GHz ECR ion source HIISI at University of Jyväskylä. An innovative plasma chamber structure with grooves at magnetic poles for larger chamber radius at poles. The hexapole will be refridgerated to sub-zero temperatures to boost the coercivity and the remanence of the permanent magnet material and to allow the use of high remanence, low intrinsic coersivity permanent magnet materials. The hexapole structure is insulated from high temperature solenoid coils and plasma chamber by vacuum. The thermal design of the structure has been made using a thermal diffusion code taking in account radiative, conductive and convective heat transfer processes. …
HIISI, New 18 GHZ ECRIS for the JYFL Accelerator Laboratory
2014
At the end of 2013 the Academy of Finland granted an infrastructure funding for the JYFL Accelerator Laboratory in order to increase beam intensities for the international user community. The primary objective is to construct a new high performance ECR ion source, HIISI (Heavy Ion Ion Source Injector), for the K130 cyclotron. Using room temperature magnets the HIISI has been designed to produce about the same magnetic field configuration as the superconducting ECRIS SUSI at NSCL/MSU for 18 GHz operation. An innovative structure will be used to maximize the radial confinement and demagnetization safety margin of the permanent magnets. The sextupole magnet is separated and insulated from the …
Status of new 18 GHz ECRIS HIISI
2018
A new 18 GHz ECR ion source HIISI is under commissioning at the Accelerator Laboratory at the University of Jyväskylä (JYFL). The main purpose of HIISI is to produce high-energy beam cocktails, e.g. Xe44+, for radiation effects testing of electronics with the K130 cyclotron. The initial commissioning results in 18+14 GHz operation with oxygen, argon and xenon are reported. The beam currents are compared to those produced by reference ion sources (JYFL 14 GHz ECRIS, GTS and SuSI). At the moment (October 2017) 560 µA of O6+ and 310 µA of Ar13+, for example, have been reached with HIISI at 2.3 kW total power. peerReviewed

Co-Creative, Re-Generative Smart Cities. Smart Cities and Planning in a Living Lab Perspective
2014
A particularly mild approach in money supply over three decades at the international level has encouraged the piling up of substantial amounts of debt through urban investment, particularly in less competitive systems . It appears therefore necessary ato elaborate stringent "urban financial statements", through a kind of digital agenda able to provide georeferenced economic indicators about structure, value and performance of urban capital, and therefore capable to serve as a guide in future allocative choices of the myriad of holders of some stake of the above urban capital. Recognizing the role of such a multiplicity of stakeholders means to radically reconsider the transcendent assumptio…
Training and Deployment as a Basis for Usability Engineering of Mobile Systems
2008
Usability engineering of mobile systems challenges existing methods and raises new concerns. Usability evaluations are frequently described as a separate discipline and in many cases usability evaluations are separate activities within the design and development of systems. This paper presents a development project where training in and the deployment of a mobile system were used to identify usability problems. The project aimed to develop a mobile system to supporting information processes for workers on building sites. An iterative usability evaluation process was conducted the process was refined and validated using two action research projects. The approach of the research was user-cent…
Usability remote evaluation: METBA system
2012
Usability as well as accessibility is a key aspect in development of human-computer interaction. This paper presents the basis of usability evaluation methodology and reviews the methodology used in empirical studies of usability evaluation for disabled people. Finally, we present a solution (METBA) as a system for managing the information related to evaluation of human behavioral observation contents that is used for the registration and management of the information derived from remote usability evaluation which complements the methodology commonly used in this research area.
