Dipartimento di Psicologia Dinamica e Clinica – Facoltà di Medicina e Psicologia - Università “Sapienza”
Viene presentata una ricerca nata allo scopo di comprendere quale rappresentazione abbiano i MMG della
prospettiva BioPsicoSociale. A tal fine, e con riferimento al solo territorio Romano, sono state condotte 29
interviste in profondità che, audio-registrate, sono state in seguito integralmente trascritte.
Le trascrizioni delle interviste sono state successivamente analizzate mediante una griglia di codifica
predisposta ad hoc e costruita al triplice scopo di:
- enucleare le differenti rappresentazioni emergenti dai medici in rapporto all’oggetto di studio;
- mettere in evidenza quali siano le effettive possibilità di diffondere la sperimentazione condotta dal
prof. Solano – sulla compresenza fra medico e psicologo – presso i MMG;
- esplorare le diverse culture espresse dai MMG che, posti tra le esigenze del territorio e quelle del
Sistema Sanitario Nazionale, ricoprono un osservatorio interessantissimo in rapporto alle attuali
necessità espresse dal contesto sociale.
Lo studio mette in evidenza alcune principali criticità sperimentate dai medici nell’esercizio del proprio
lavoro e fornisce informazioni preziose sulla possibilità di orientare la definizione dell’assistenza di base
territoriale in rapporto alle nuove declinazioni (vedi ad es. le case della salute)
OASIS ’21 Chairs’ Welcome
No full textIt is our great pleasure to welcome you to the 2021 Workshop on Open Challenges in Online Social Networks - OASIS 2021, held in conjunction with the 2021 ACM Conference on Hypertext and Social Media - ACM HT 2021. The diffusion of Online Social Networks (OSNs) has had a profound effect on the way we interact and a deep impact on society and business. OSNs have helped people to communicate, breaking down the geographical barriers that restricted communication. Through social networks, virtual communication, sharing of information, community participation is possible even among people in uncomfortable conditions. Today, OSNs are one of the main parts of daily life by affecting sociality, but they are also important channels through which information travels faster than ever. Analysis of OSN can help to foresee events to manage critical scenarios. The rapid growth in popularity has opened new challenging problems which involve numerous fields in computer science. These issues have implications on social graph analysis, trust and security, and so on. Moreover, privacy issues and the usage of mobile devices has opened new research fields in the design of decentralised online social networks, which can be considered one of the most important challenges. Furthermore, the current improvement concerning the study and the proposal of new approaches for Social Networks and Media involve not only complex network analysis, and, in particular, the decentralisation of social services, but also the introduction of new AI solutions

Studying micro-communities in facebook communities
No full textIn the visionary view of the future Internet, named the Next Generation Internet, a current idea is to have a user-centric approach where human behavior models will be used to define the networks or to manage services. During the last years, a great trend in current Social Media platforms is to offer the opportunity to establish and join groups of people online. Despite human behaviour in current Online Social Media have been studied in depth, characteristics of these aggregations of people in content-based communities are still unknown. In this paper, we propose an evaluation of micro-communities of users inside the big network of Facebook groups to understand how and when users are active, and to evaluate the evolution of these micro-communities over time. Results show that almost all groups showed interactions-based communities. We found out that in all cases there is one massive core community which attracts small communities
From NFT 1.0 to NFT 2.0: A Review of the Evolution of Non-Fungible Tokens
No full textNon-fungible tokens (NFT) represent one of the most important technologies in the space of Web3. Thanks to NFTs, digital or physical assets can be tokenised to represent their ownership through the usage of smart contracts and blockchains. The first generation of this technology, called NFT 1.0, considers static tokens described by a set of metadata that cannot be changed after token creation. The static nature prevents their wide spread as they do not support any meaningful user interaction. For this reason, its evolution, called NFT 2.0, has been proposed to make tokens interactive and dynamic and enhance user experience, opening the possibility to use NFTs in more ways and scenarios. The purpose of this article is to review the transition from NFT 1.0 to NFT 2.0, focusing on the newly introduced properties and features and the rising challenges. In particular, we discuss the technical aspects of blockchain technology and its impact on NFTs. We provide a detailed description of NFT properties and standards on various blockchains and discuss the support of the most important blockchains for NFTs. Then, we discuss the properties and features introduced by NFT 2.0 and detail the technical challenges related to metadata and dynamism. Lastly, we conclude by highlighting the new application scenarios opened by NFT 2.0. This review paper serves as a solid base for future research on the topic as it highlights the current technological challenges that must be addressed to help a wide adoption of NFTs 2.0
Far fronte. Social worker e cambiamenti del welfare
No full textIl capitolo illustra e discute i principali risultati di una ricerca nazionale sui cambiamenti del lavoro sociale seguiti alla diffusione dei nuovi orientamenti delle politiche di welfare dagli anni ’90 in poi. Mentre i contenuti e i processi delle riforme del welfare sono stati oggetto di ripetuta attenzione e i cambiamenti delle organizzazioni del welfare sono ormai noti nella loro configurazione generale, resta ancora da fare piena luce sui rapporti tra mutamenti delle politiche di welfare, trasformazioni dei servizi sociali e cambiamenti del lavoro sociale. Al proposito, la tesi degli «effetti corrosivi» sul lavoro sociale (Healy, 2009) - pur confermata autorevolmente e con riferimento a molteplici contesti nazionali - rischia di essere costruita su interpretazioni eccessivamente meccanicistiche dei rapporti tra politiche, organizzazioni e lavoro sociale (Guidi, 2011).
Per contribuire al dibattito il capitolo richiama alcuni caratteri fondamentali delle riforme del sistema di welfare attingendo prioritariamente agli studi di matrice neo-istituzionalista e prova a rappresentare meglio i rapporti tra politiche, organizzazioni e lavoro sociale sulla base dell’approccio bottom-up all’‘implementazione’ delle politiche pubbliche e della riflessione socio-cognitivista sulle organizzazioni. Presentiamo quindi i risultati di una rassegna critica sistematica della letteratura europea dal 1992 al 2014. Nella seconda parte del capitolo, dopo averne esposto le ipotesi e i metodi, illustreremo i risultati di due attività di ricerca sul campo, una (quantitativa) finalizzata alla definizione dei profili professionali degli assistenti sociali nei diversi modelli regionali di welfare in Italia, l’altra (qualitativa) sull’autorappresentazione, la percezione di sé e le più diffuse immagini delle professioni sociali in Toscana
SocialFi: towards the new shape of social media
No full textDecentralized Finance (DeFi) is considered a new vision of banking and financial services based on Peer-to-Peer technology, and in particular on the blockchain technology. Since 2020, DeFi has started to develop in the cryptocurrency markets. Then, with the increase in popularity of digital platforms such as Twitter, Facebook and Instagram, and with the launch of the Metaverse, DeFi has been introduced into the Social environment by the combination of social networking and finance in the blockchain. This new shape of DeFi has been called Social Finance (SocialFi). SocialFi can be seen as the social influence on any medium that can be tokenized, allowing to get monetary benefits from being part of SocialFi platforms. In detail, SocialFi has a special feature that is decentralized, open and user-controlled, and it started to be adopted by the communities. The main component of SocialFi is the Social token used to reward people. In this paper, we describe in detail the concept of SocialFi, and we discuss its application on future Social Media platforms.</jats:p
Dynamic Community Structure in Online Social Groups
No full textOne of the main ideas about the Internet is to rethink its services in a user-centric fashion. This fact translates to having human-scale services with devices that will become smarter and make decisions in place of their respective owners. Online Social Networks and, in particular, Online Social Groups, such as Facebook Groups, will be at the epicentre of this revolution because of their great relevance in the current society. Despite the vast number of studies on human behaviour in Online Social Media, the characteristics of Online Social Groups are still unknown. In this paper, we propose a dynamic community detection driven study of the structure of users inside Facebook Groups. The communities are extracted considering the interactions among the members of a group and it aims at searching dense communication groups of users, and the evolution of the communication groups over time, in order to discover social properties of Online Social Groups. The analysis is carried out considering the activity of 17 Facebook Groups, using 8 community detection algorithms and considering 2 possible interaction lifespans. Results show that interaction communities in OSGs are very fragmented but community detection tools are capable of uncovering relevant structures. The study of the community quality gives important insights about the community structure and increasing the interaction lifespan does not necessarily result in more clusterized or bigger communities
Interaction Communities in Blockchain Online Social Media
No full textSurfing Online Social Media (OSM) websites have become a daily activity for a large number of people worldwide. People use OSMs to satisfy their innate need to socialise, but also as a source of information or to share personal facts. Thanks to the massive success of cryptocurrencies, the blockchain technology gained popularity among researchers, giving birth to a new generation of social media. Steemit is the most well-known blockchain-based social media, and it is based on the public blockchain Steem. Steemit employs Steem as data storage, and to implement a rewarding mechanism that grants cryptocurrency to pieces of content that are considered relevant by the users. Steem represents the first experiment that integrates OSMs and an economic rewarding system on the same platform, and in this paper, we inspect the interactions among the users from a community perspective. We apply two community detection algorithms on five graphs that model just as many facets of the Steem blockchain and test the detected structure against three measures for community structure evaluation. Findings show that communities tend to be very large, index of how much users are encouraged to interact as much as possible, and in particular, in the monetary graph, we detect a large number of the block producers of Steem
