Mobile Communities in Developing Countries
2010
The number of mobile devices has exceeded four billions and is still growing. Especially in developing countries mobile devices are often the only access to Internet and digital services. In the most developed countries laptops, Wi-Fi and faster and faster wireless telecom networks have for long time made mobile access to various digital services possible while on the move. Still, large and instant mobile communities can only rely on more portable devices, such as mobile phones. In this paper we will analyze various mobile communities and the support they are offered by the social media sites. We will discuss the phenomena encountered in developing countries, like how the mobile technology …
Message-driven factors influencing opening and forwarding of mobile advertising messages
2015
This work aims to analyse the influence of message-driven factors -informativeness, ubiquity, frequency and personalization- on consumer attitude and behaviour -opening and forwarding- towards mobile advertising messages. A theoretical model was developed and empirically tested using a sample of 355 Spanish teenager mobile users. Findings show that frequency is the dimension accounting the most -and significantly- of the four message-driven factors analysed on attitude toward mobile advertising. Attitude has a significant effect on acceptance of mobile advertising messages. Message-driven factors – in a direct way and indirectly through attitude toward mobile - lead to consumer opening and …
Barriers and paradoxical recommendation behaviour in online to offline (O2O) services. A convergent mixed-method study
2021
Mobile apps offering online to offline (O2O) services act as aggregators providing interface for delivery of required products and services at a preferred location. Despite offering multiple affordances, many O2O services have not diffused as anticipated, indicating the existence of consumer resistance towards them. One such example is that of food delivery apps (FDAs), which are experiencing resistance at both the pre-adoption and post-adoption stage. However, there are scarce empirical findings explicating the pre-and post-adoption barriers perceived to be associated with FDAs. The present study addresses this gap by utilising the Innovation Resistance Theory (IRT) and a convergent mixed-…
The Antecedents of Consumers’ Negative Attitudes Toward SMS Advertising: A Theoretical Framework and Empirical Study
2013
Short message service (SMS) advertising refers to the transmission of advertising via mobile phones in the form of text-based messages (Haghirian, Madlberger, and Tanuskova 2005). Recent marketing research indicates that investigations on consumers’ attitudes toward SMS advertising are limited, and empirical examination of antecedents that negatively influence attitudes toward SMS advertising is even scarcer. As a consequence of this lack of knowledge, current practices of mobile advertising might be ineffective. This research examines irritation, privacy concerns, and intrusiveness perception as main factors that provoke a negative attitude toward SMS advertising. Using structural equation…
“Krokodil”—Revival of an Old Drug with New Problems
2012
In order to summarize current knowledge about the drug "Krokodil" a systematic review including a literature search of the databases PubMed, Embase, Scopus, and Google was conducted in December 2011. According to information acquired, "Krokodil" is a mixture of several substances and was first reported to have been used in Russia in 2003. The core agent of "Krokodil" is desomorphine, an opioid-analogue that can be easily and cheaply manufactured by oneself. Self-production results in a contaminated suspension that is injected intravenously. Due to its pharmacologic features, desomorphine shows a high potential to cause dependence. Against the background of first possible cases of "Krokodil"…
Crowdsourcing Cultural Heritage: From 3D Modeling to the Engagement of Young Generations
2016
Monitoring, digitizing and archiving museum artworks represent an important socio-cultural accomplishment and an overcoming in digital preservation today. Cultural heritage is constantly under threat of terrorist attacks and natural disaster. The high costs related to documentation task have prevented a constantly and massive survey activity. The low cost 3D image based acquisition and elaboration techniques of an object, allow to carry out a 3D photorealistic model in a short time. Therefore, a lot of museum adopted these techniques for the artworks archiving. Crowdsourcing activities can significantly speed up survey and elaboration procedures. If, on the one hand, these initiatives can h…
What Motivates Internet Users to Search for Asperger Syndrome and Autism on Google?
2020
Social campaigns are carried out to promote autism spectrum disorder (ASD) awareness, normalization, and visibility. The internet helps to shape perceptions of Asperger syndrome and autism. In fact, these campaigns often coincide with the increase in searches for both diagnoses on Google. We have two study objectives: to use Google Trends to identify the annual time points from 2015 to 2019 with the highest Google search traffic in Spain for the terms &ldquo
A secret sharing scheme for anonymous DNS queries
2013
Since its adoption in the early 90's, several privacy concerns have emerged about the Domain Name System (DNS). By collecting the DNS queries performed by each user, it is possible to characterize habits, interests and other sensitive data of the users. Usually, users resolve their {\em url} requests by querying the DSN server belonging to their Internet Service Provider (ISP) and therefore they assume they can trust it. However, different DNS servers can be used, by revealing sensitive data to a partially untrusted entity that can collect and sell this data for several purposes (target advertising, user profiling, etc.). In this paper we address the possibility to integrate tools in the cu…
Young People and the Dark Side of Social Media: Possible Threats to National Security
2020
Social media is increasingly becoming a forum for criminality, misuse, and hate speech, as there are no filters or other controlling mechanisms to filter user-generated content.Furthermore, disinformation and propaganda are becoming more sophisticated and harder to track. Hence, this dark side of social media can pose a viable threat to national security. Future generations will be born into an environment of polluted and polarised online information networks. Consequently, young people, many of whom use social media on a daily basis, will have to find ways to survive in these circumstances,often without the help, knowledge, or experience of earlier generations. Thus, young people are at ri…
Two tiered privacy enhanced intrusion detection system architecture
2009
The paper describes an architecture for privacy-enhanced intrusion detection systems, that separates privacy-invasive and privacy-preserving operations. This can be useful in cases where less sensitive network monitoring is outsourced to a third party and more sensitive network monitoring operations and data forensics are performed in-house or by law enforcement agencies.
