Using random networks to study the dynamics of respiratory syncytial virus (RSV) in the Spanish region of Valencia
2011
[EN] Seasonal fluctuations in the incidence of several respiratory infections are a feature of epidemiological surveys all around the world. This phenomenon is characteristic of influenza and respiratory syncytial virus pandemics. However, the explanation of the seasonal outbreaks of these diseases remains poorly understood. Many statistical studies have been carried out in order to provide a correlation of the outbreaks with climatic or social factors without achieving a definitive conclusion. Here we show that, in a random social network, self-sustained seasonal epidemics emerge as a process modulated by the infection probability and the immunity period after recovering from the infection…
Towards a fuzzy-linguistic based social network sentiment-expression system
2015
Liking allows users of Social Networks, blogs and online magazines to express their support of posts and artifacts by a simple click. Such function is very popular but lacks semantic power, and some platforms have augmented it by allowing to choose a pictographic depiction corresponding to a feeling. What is gained in depth is lost in simplicity, and the wide acceptance liking has enjoyed did not carried to the sentiment version. We outline a sentiment-expression hybrid system based on textual analysis and linguistic fuzzy Markov chains overcoming the intrinsic limitations of liking without burdening the user with complex choices.
Histoedu, social networks and history of education: pedagogical past from a present perspective
2016
This article presents some preliminary results and considerations about a R&D project about the use of ICTs and social media to do research on educational history. The progress achieved regarding the improvement of social and scientific communication, the significance of the learning process and the motivation shown by the academic community, make us point out the need to consolidate what we have been referring to as history of education 2.0. There are many chances available to learn and to build up knowledge in a shared way, and they challenge us to generate network knowledge and to cooperate in order to: spread our research, get to know other approaches to work, share resources and ex…
Which has more influence on perception of pseudo-therapies: the media’s information, friends or acquaintances opinion, or educational background?
2019
This study analyses the discourses of Education and Journalism students in order to understand their perception of complementary and alternative therapies. Likewise, to know if educational background or friends or acquaintances opinion has a more considerable influence on their knowledge and use of these socially controversial techniques than the media. This study uses qualitative research methods based upon 12 discussion groups with 102 participants. Once transcriptions were completed, discourse analysis was conducted using linguistic corpus software (T-LAB. 9.1.). In the design of the research, these students were selected for their social involvement in their future careers, such as when…

Bakalaura darba tēma ir latviešu un igauņu jauniešu sociālo tīklu lietošanas paradumi. Mūsdienās ir plašs sociālo tīklu izvēles klāsts, no kā jaunieši var izvēlēties izmantot sev vēlamos, bet tas katram indivīdam var atšķirties, tāpat kā to lietošanas paradumi. Bakalaura darba mērķis ir noskaidrot latviešu un igauņu jauniešu sociālo tīklu lietošanas paradumu atšķirības, kuras var radīt abu valstu atšķirīgā mediju lietotprasmes iesaiste skolu mācību programmās. Darba teorijas daļā tiek apskatīta mediju lietotprasme, sociālo tīklu attīstība, digitālās paaudzes jēdziens, atklājumi par jauniešu drošību un privātumu sociālajos tīklos, kā arī lietojuma un apmierinājuma teorija. Ar anketēšanas un …
Taking care of everyone’s business: interpreting Sicilian Mafia embedment through spatial network analysis
2022
Mafia-type organisations often have a strong geographical and cultural entrenchment in the territory they belong. However, their analysis as a spatially networked social structure is still missing. A combined socio-spatial network analysis is presented here, through the demise of a large police operation called Operazione Perseo in 2008. This approach is developed in two ways. At first, a visual representation of the social network of this large group of mafiosi embedded in a geographical space is presented. Three main salient territorial features of the network are thus highlighted. A high density of links in some neighbourhoods, as well as connections across different Mandamenti, the terr…
Conflict and segregation in networks: An experiment on the interplay between individual preferences and social influence
2016
We examine the interplay between a person's individual preference and the social influence others exert. We provide a model of network relationships with conflicting preferences, where individuals are better off coordinating with those around them, but where not all have a preference for the same action. We test our model in an experiment, varying the level of conflicting preferences between individuals. Our findings suggest that preferences are more salient than social influence, under conflicting preferences: subjects relate mainly with others who have the same preferences. This leads to two undesirable outcomes: network segregation and social inefficiency. The same force that helps peopl…
The impact of user’s availability on On-line Ego Networks: a Facebook analysis
2016
We have defined and implemented a Facebook application to log a Facebook dataset.We have studied and validated the structural properties of the whole dataset and of the Dunbar ego networks.We have analyzed the interactions of the users.The availability of the users in the Dunbar ego networks have been investigated.Our results reveal the presence of the temporal homophily property in the Dunbar ego networks. Online Social Networks (OSNs) are the most popular applications in todays Internet and they have changed the way people interact with each other. Understanding the structural properties of OSNs and, in particular, how users behave when they connect to OSNs is crucial for designing user-c…
An Analysis of the Internal Organization of Facebook Groups
2019
With the rapid development and growth of online social networks (OSNs), researchers have been pushed forward to improve the knowledge of these complex networks by analyzing several aspects, such as the types of social media, the structural properties of the network, or the interaction patterns among users. In particular, a relevant effort has been devoted to the study and identification of cohesive groups of users in OSNs (also referred as communities) because they are the basic building block of each OSN. While several research works on groups in OSNs have mainly focused on identifying the types of groups and the contents created by their members, the analysis of internal organizations of …
Subjectivity on the Web: The Case of Social Networks and the H1N1 emergency
2010
Blogs are extensively used for personal accounts and news reports. In particular, health blogs can be considered as both information sources and communication channels be- tween Science and Society, since they face the growing need for information among non-insiders. This study is concerned with the dimension of reality portrayed in blog comment en- tries; focusing particularly on participants'' representation of facts and their commit- ment to the truth of the proposition. The framework for this study has been shaped by the typologies in Chafe (1986), Willett (1988), Van der Auwera and Plungian (1998), Plungian (2001), Marìn (2002, 2004). Data are taken from three health and science we- bl…
