Literature, social media and questionnaire surveys identify relevant conservation areas for Carcharhinus species in the Mediterranean Sea
2023
Sharks support ecosystems’ health, but their populations are facing severe declines worldwide. Knowledge gaps on shark distribution and the negative human perception of them still represent a barrier to the implementation of effective conservation measures. Here we carried out a regional-scale analysis in the Mediterranean Sea using data on requiem shark catches and sightings available in the scientific literature and on social media platforms to: 1) depict the distribution of Carcharhinus species across the basin, 2) identify potentially relevant areas for their conservation, and 3) evaluate people’s attitude toward shark protection. In addition, we administered 112 questionnaires in one o…
The risk of sexual-erotic online behavior in adolescents – Which personality factors predict sexting and grooming victimization?
2021
Abstract Information and communication technologies provide new opportunities for adolescents to establish and maintain intimate relationships, as well as exploring their sexuality. However, the young population is particularly vulnerable to becoming victims of violence or online abuse. The aim of this study was to understand to which extent the personality factors (extraversion, narcissism, lack of empathy and disinhibition) are related to sexting and online grooming victimization. The participants were 1763 adolescents between 12 and 16 years (M = 14.56, SD = 1.16, 50.99% girls). A cross-sectional design with self-report data was used, analyzed by structural equation modeling (SEM). The r…
Investigating label suggestions for opinion mining in German Covid-19 social media
2021
This work investigates the use of interactively updated label suggestions to improve upon the efficiency of gathering annotations on the task of opinion mining in German Covid-19 social media data. We develop guidelines to conduct a controlled annotation study with social science students and find that suggestions from a model trained on a small, expert-annotated dataset already lead to a substantial improvement - in terms of inter-annotator agreement(+.14 Fleiss' $\kappa$) and annotation quality - compared to students that do not receive any label suggestions. We further find that label suggestions from interactively trained models do not lead to an improvement over suggestions from a stat…
An exploratory study of COVID-19 misinformation on Twitter.
2020
During the COVID-19 pandemic, social media has become a home ground for misinformation. To tackle this infodemic, scientific oversight, as well as a better understanding by practitioners in crisis management, is needed. We have conducted an exploratory study into the propagation, authors and content of misinformation on Twitter around the topic of COVID-19 in order to gain early insights. We have collected all tweets mentioned in the verdicts of fact-checked claims related to COVID-19 by over 92 professional fact-checking organisations between January and mid-July 2020 and share this corpus with the community. This resulted in 1 500 tweets relating to 1 274 false and 276 partially false cla…
Effectiveness of Data-Driven Induction of Semantic Spaces and Traditional Classifiers for Sarcasm Detection
2019
Irony and sarcasm are two complex linguistic phenomena that are widely used in everyday language and especially over the social media, but they represent two serious issues for automated text understanding. Many labeled corpora have been extracted from several sources to accomplish this task, and it seems that sarcasm is conveyed in different ways for different domains. Nonetheless, very little work has been done for comparing different methods among the available corpora. Furthermore, usually, each author collects and uses their own datasets to evaluate his own method. In this paper, we show that sarcasm detection can be tackled by applying classical machine learning algorithms to input te…
Social media as a strategic marketing tool in the Sicilian wine industry: Evidence from Facebook
2017
Abstract Over the last few years, many companies have integrated social media, and social networking sites in particular, into their communication and media plan, leading to a deep transformation of the organizational models and changing the companies׳ marketing dynamics. This study has dual aims: first, to recognize and validate the firm׳s social media (SM) efforts in its use of the Facebook platform; second, to examine the relationships among the firm׳s SM efforts and some firm and managerial characteristics. In order to achieve these research aims, data on 45 wineries were collected and analysed, using a model that considers three different dimensions of the firms׳ activity on the social…
Facebook’s ad hoc groups: a potential source of communicative power of networked citizens
2017
Ad hoc groups (sporadically formed on social network sites for achieving particular common objectives) have been seen as a public space for citizen participation and debate. This study focuses on Facebook’s ad hoc groups in Finland. The aim is to detect the potential of these groups to enhance networked citizens’ communicative power for raising societally important issues to public agenda and initiate changes in society. We suggest a categorization of the groups according to their missions, and present their members’ specific motivations and objectives through an online survey. Despite the general entertainment-orientation and self-referential nature of social media, the results show that a…
Issues of Ethics and Methods in Studying Social Media
2016
The Editorial raises some challenging ethical and methodological aspects of Internet based research (such as protection of informational privacy, informed consent, general ethical guidelines vs case-based approach), which are further discussed in the five articles of this special issue.
What is the role of social media in several overtones of CSR communication? The case of the wine industry in the Southern Italian regions
2019
Purpose The purpose of this paper is to understand whether the companies most involved in communicating their responsible behaviour externally are those most active on the social media (SM) platform, with a philanthropic purpose rather than strictly aimed at economic aspects. Design/methodology/approach The authors, first, assess firms’ efforts on the SM platform using the model proposed by Chung et al. (2014), and, second, the authors analyze the content of messages in order to verify what dimensions of the corporate social responsibility (CSR) they contain. A multivariate modelling has been performed in order to verify whether the wineries that take most care to communicate their respons…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …
