The Protection of the Weaker Parties in the Platform Economy
2018
Known by many names – platform, sharing, peer-to-peer (p2p), collaborative economy, and so on - entirely new business models have emerged in recent years, whereby online platforms use digital technologies to connect distinct groups of users in order to facilitate transactions for the exchange of assets and services. This dramatic shift in business organisation and market structure has opened an intense debate on the persisting need for those regulatory measures that typically protect the weaker party in bilateral business-to-consumer transactions. Widespread calls for a more “levelled playing field” makes a strong argument for reconsidering the scope of regulation and delegating regulatory …

Touristification, Sharing Economies and the New Geography of Urban Conflicts
2018
The aim of this study was to address the highly controversial problem of the increasing touristification of urban centers, analyzing the case of Valencia. The paper begins with a theoretical reflection to disambiguate the term &ldquo
Urban mobility and social inclusion of migrant people: The role of sharing mobility. A qualitative study
2020
The relationships between urban mobility and the process of social inclusion/exclusion have been highlighted by several scholars (i.e., LUCAS 2012; RICCI 2016). The possibility to move freely to reach in an easy and accessible way the destinations required to satisfy daily needs is a key factor linked to well-being of citizens, as well as to their possibility to actively participate in the life of their community. From this perspective, shortfalls in the urban transport system may have negative effects on the social inclusion of categories at risk of social marginalization (i.e., people living in the suburbs, migrant people). The current paper is aimed at deepening the understanding of thes…
A charge reconstruction algorithm for DAMPE silicon microstrip detectors
2019
Abstract The DArk Matter Particle Explorer (DAMPE) can detect electrons and photons from 5 GeV to 10 TeV and charged nuclei from a few tens of GeV to 100 TeV. The silicon–tungstentracker (STK), which is composed of 768 singled-sided silicon microstrip detectors, is one of four subdetectors in DAMPE providing photon conversion , track reconstruction, and charge identification for relativistic charged particles. This paper focuses on the charge identification performance of the STK detector. The charge response depends mainly on the incident angle and the impact position of the incoming particle. To improve the charge resolution, a reconstruction algorithm to correct for these parameters was …
Performance of production modules of the Belle II pixel detector in a high-energy particle beam
2021
The Belle II experiment at the Super B factory SuperKEKB, an asymmetric $e^+e^-$ collider located in Tsukuba, Japan, is tailored to perform precision B physics measurements. The centre of mass energy of the collisions is equal to the rest mass of the $\Upsilon(4S)$ resonance of $m_{\Upsilon(4S)} = 10.58\,\rm GeV$. A high vertex resolution is essential for measuring the decay vertices of B mesons. Typical momenta of the decay products are ranging from a few tens of MeV to a few GeV and multiple scattering has a significant impact on the vertex resolution. The VerteX Detector (VXD) for Belle II is therefore designed to have as little material as possible inside the acceptance region. Especial…
Digital performance improvements of a CdTe pixel detector for high flux energy-resolved X-ray imaging
2015
Abstract Photon counting detectors with energy resolving capabilities are desired for high flux X-ray imaging. In this work, we present the performance of a pixelated Schottky Al/p-CdTe/Pt detector (4×4) coupled to a custom-designed digital readout electronics for high flux measurements. The detector (4×4×2 mm 3 ) has an anode layout based on an array of 16 pixels with a geometric pitch of 1 mm (pixel size of 0.6 mm). The 4-channel readout electronics is able to continuously digitize and process the signals from each pixel, performing multi-parameter analysis (event arrival time, pulse shape, pulse height, pulse time width, etc.) even at high fluxes and at different throughput and energy re…
Energy Recovery of Multiple Charge Sharing Events in Room Temperature Semiconductor Pixel Detectors
2021
Multiple coincidence events from charge-sharing and fluorescent cross-talk are typical drawbacks in room-temperature semiconductor pixel detectors. The mitigation of these distortions in the measured energy spectra, using charge-sharing discrimination (CSD) and charge-sharing addition (CSA) techniques, is always a trade-off between counting efficiency and energy resolution. The energy recovery of multiple coincidence events is still challenging due to the presence of charge losses after CSA. In this work, we will present original techniques able to correct charge losses after CSA even when multiple pixels are involved. Sub-millimeter cadmium–zinc–telluride (CdZnTe or CZT) pixel detectors we…
La tutela del contraente debole nella platform economy
2018
Negli ultimi anni si è affermato un nuovo modello di attività produttiva nel quale piattaforme digitali mettono in contatto gruppi interdipendenti di agenti economici per facilitare lo scambio di beni e l’erogazione di servizi. Dinanzi a questa trasformazione nell’organizzazione d’impresa, nel coordinamento del lavoro e nella struttura dei mercati, il diffuso appello a stabilire un “terreno di gioco neutrale” diviene la premessa per proporre la deregolamentazione di interi comparti economici valorizzando la capacità di autogoverno delle piattaforme. Mentre le reazioni a queste proposte sono confinate quasi esclusivamente alla questione del lavoro, è mancata finora un’analisi più generale de…
Exploring Collective Action Dynamics in Online Communities from a Critical Realist Perspective
2016
Scholars have been increasingly studying Online Communities (OCs) for a variety of purposes, focusing on issues like individual motivation, knowledge sharing, and governance structure. Few studies focused on the entanglement among technology, people, and organizational structures that support working dynamics within OCs. This paper addresses this issue by exploring causal mechanisms sustaining the collective actions of OCs through a retroduction process. Based on the study of the OC of an Italian political movement, the Five Star Movement, the concept of affordance is involved to describe the generative mechanisms and new affordances are identified on collective action within OCs. Our work …
