Social Network Analysis and Qualitative Interviews for Assessing Geographic Characteristics of Tourism Business Networks.

2015

This study integrates quantitative social network analysis (SNA) and qualitative interviews for understanding tourism business links in isolated communities through analysing spatial characteristics. Two case studies are used, the Surselva-Gotthard region in the Swiss Alps and Longyearbyen in the Arctic archipelago of Svalbard, to test the spatial characteristics of physical proximity, isolation, and smallness for understanding tourism business links. In the larger Surselva-Gotthard region, we found a strong relationship between geographic separation of the three communities on compartmentalization of the collaboration network. A small set of businesses played a central role in steering col…

Social media as a place to see and be seen : Exploring factors affecting job attainment via social media

2023

Job seekers can utilize social media platforms to actively search for job opportunities and also receive unsolicited job offers from recruiters and employers. Using data from a representative sample of Finnish social media users, this article studies both aspects of social media job attainment by analyzing how much individuals successfully apply for jobs and get recruited to positions through social media. Results show that the prevalence of successfully applying to jobs through social media does not differ statistically between socio-economic groups, but the prevalence of getting recruited to jobs through social media is greater within higher socio-economic groups. LinkedIn users are more …

Criminal networks analysis in missing data scenarios through graph distances.

2021

Data collected in criminal investigations may suffer from: (i) incompleteness, due to the covert nature of criminal organisations; (ii) incorrectness, caused by either unintentional data collection errors and intentional deception by criminals; (iii) inconsistency, when the same information is collected into law enforcement databases multiple times, or in different formats. In this paper we analyse nine real criminal networks of different nature (i.e., Mafia networks, criminal street gangs and terrorist organizations) in order to quantify the impact of incomplete data and to determine which network type is most affected by it. The networks are firstly pruned following two specific methods: …

Communication of Dienvidkurzemes region libraries on social media during Covid-19

2022

Jau vairāk nekā desmit gadus dažādas sociālo tīklu vietnes lielai sabiedrības daļai ir kļuvušas par galveno saziņas veidu ar draugiem, radiem, kā arī ar uzņēmumiem un valsts pārvaldes iestādēm, tai skaitā ar bibliotēkām. Covid-19 laiks parādīja to, ka sociālo tīklu vietnes patiesi ir nozīmīgs komunikācijas kanāls daudziem uzņēmumiem un organizācijām. Autores pētījuma mērķis ir noskaidrot, kā Dienvidkurzemes novada publiskajās bibliotēkās mainījās informācijas nodošanas paradumi to klientiem un lietotājiem un vai komunikācija sociālo tīklu vietnēs kļuva aktīvāka. Lai mērķi sasniegtu, autore veica aptaujas ar lietotājiem un bibliotēku darbiniekiem, kā arī tika veikta dokumentu analīze Dienvid…

Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis

2014

Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…

Disrupting resilient criminal networks through data analysis: The case of Sicilian Mafia

2020

Compared to other types of social networks, criminal networks present hard challenges, due to their strong resilience to disruption, which poses severe hurdles to law-enforcement agencies. Herein, we borrow methods and tools from Social Network Analysis to (i) unveil the structure of Sicilian Mafia gangs, based on two real-world datasets, and (ii) gain insights as to how to efficiently disrupt them. Mafia networks have peculiar features, due to the links distribution and strength, which makes them very different from other social networks, and extremely robust to exogenous perturbations. Analysts are also faced with the difficulty in collecting reliable datasets that accurately describe the…

A comparative analysis of the statistical properties of large mobile phone calling networks.

2014

Mobile phone calling is one of the most widely used communication methods in modern society. The records of calls among mobile phone users provide us a valuable proxy for the understanding of human communication patterns embedded in social networks. Mobile phone users call each other forming a directed calling network. If only reciprocal calls are considered, we obtain an undirected mutual calling network. The preferential communication behavior between two connected users can be statistically tested and it results in two Bonferroni networks with statistically validated edges. We perform a comparative analysis of the statistical properties of these four networks, which are constructed from …

Academic Contest and Social Networking to Promote Technology and Information Literacy among University Students

2012

Abstract Spanish universities have recently adapted their studies to the requirements of the European Higher Education Area (EHEA). This process has involved the consideration of the development of computer and informational skills as an academic objective. In order to develop these skills, among other activities, an informative video has been disseminated. The design of the communication campaign, developed through viral marketing and social networks has been the result of and empirical research carried out by students of the University of Valencia. This paper describes the research objectives, questions, techniques and main findings.
