How Can Secure Websites Improve Buying Intention?
2014
A conceptual model is proposed to show 3 effects of augmenting security perceptions (more pleasure, less perceived risk and higher trust) in order to improve buying intention. The role of usability in reinforcing these direct and indirect security effects has also been tested. This study examines the reinforcement of previous relationships in highly usable contexts. To test this, a fictitious website was designed for a nonexistent clothing company directed at the segment of middle class consumers. Two blocks of changes were made to alter website usability: one concerning website speed and the other related to ease of use. Results for a study sample of 170 respondents show that in usable con…
Signaling through the 2008 Beijing Olympics—Using Mega Sport Events to Change the Perception and Image of the Host
2011
Abstract This paper provides an analysis on internet news reports about the Beijing Olympics 2008 and how China signaled throughout the event to external target groups. The analysis shows how the geographical areas China, USA, Europe and the “Rest of the World” perceived the Games. The results were interpreted regarding the principal agent theories' signaling to reduce information asymmetry for business and tourism and costly signaling to generate symbolic capital. Seven hundred and forty news reports were collected between 1 July and 30 September 2008, using Google Alerts with the keywords “Olympic Games Beijing 2008”. The reports were analysed with a quantitative content analysis using a …
On Gauss and Gaussian Legends: A Quiz
2018
For the last few years, students in my history of mathematics course have been required to do a bit of research on the web. Each of them chooses from a list of specially chosen questions designed to make them ponder whether the information they find on standard internet sites is solidly grounded and clearly sourced, or whether subsequent research (pursued in such unlikely places as the local university library) might lead a person to doubt what one reads online. The idea here is not to push for a definitive answer; in many cases, this would be a hopeless undertaking anyway. Instead, I ask students merely to report on what they found and how they went about tracking down the information cite…
A User-Centered Approach to Digital Household Risk Management
2020
Internet of Things (IoT) is expected to become as common as electricity (OECD 2016) and there is a high probability for connected homes to become central parts of critical societal. IoT technologies might access, manage and record sensitive data about citizens and, as they become more and more pervasive, unintended data breaches reports increase every week. However, most of the tools designed to protect users’ privacy and personal data on IoT devices fail to contemplate the experience of persons with disabilities, elderly and other vulnerable categories of people. As a consequence, they are forced to rely on the help of family members or other related persons with technical skills, as frequ…
Proactive Future Internet: Smart Semantic Middleware for Overlay Architecture
2009
Some initiatives towards Future Internet, e.g., GENI, DARPA's Active Networks, argue the need for programmability of the network components. Some other initiatives extend this with argumentation for declarative networking, where the behavior of a network component is specified using some high-level declarative language, with a software-based engine implementing the behavior based on that specification. Our Proactive Future Internet (PROFI) vision follows these initiatives targeting also the following two problems: interoperability of the network elements programmed by different organizations, and the need for flexible cooperation among network elements, including coordination, conflict reso…
Performance evaluation of a measurement-based algorithm for distributed admission control in a DiffServ framework
2002
Distributed Admission Control in IP DiffServ environments is an emerging and promising research area. Distributed admission control solutions share the idea that no coordination among network routers (i.e. explicit signaling) is necessary, when the decision whether to admit or reject a new offered flow is pushed to the edge of the IP network. Proposed solutions differ in the degree of complexity required in internal network routers, and result in a different robustness and effectiveness in controlling the accepted traffic. This paper builds on a recently proposed distributed admission control solution, called GRIP (Gauge&Gate Reservation with Independent Probing), designed to integrate the …
A Multi-Relay Cooperative Automatic Repeat Request Protocol in Wireless Networks
2010
This paper proposes a Multi-relay Cooperative Automatic Repeat ReQuest protocol (MC-ARQ) for IEEE 802.11 based wireless networks. The proposed distributed relay selection scheme not only selects the best relays but also solves the collision problem among multiple contending relays, by sorting the relays in the network according to their instantaneous channel quality with the destination node. No prior information or explicit signaling among relay nodes is required. Both analytical and simulation results show that significant benefits can be achieved with the MC-ARQ protocol, compared with both the recently proposed PRCSMA scheme and the original non-cooperative DCF scheme.
Influence of online shopping information dependency and innovativeness on internet shopping adoption
2008
PurposeThe paper's purpose is to analyse the influence of online shopping information dependency and innovativeness on the acceptance of internet shopping.Design/methodology/approachThe impact of online shopping information dependency, domain‐specific innovativeness and technology acceptance model (TAM) variables on future shopping intention has been tested through structural equation modelling techniques. The sample consisted of 465 Spanish consumers who had never purchased online.FindingsData analysis shows that consumer innovativeness and online shopping information dependency have a direct and positive influence on future online shopping intention and that the basic TAM hypotheses are f…
Symbols and Meanings in Breast Cancer Awareness Campaigns
2013
This article examines symbols and meanings in breast cancer awareness campaigns, and the ways in which multifarious actors draw attention to the disease. We discuss what the various campaigns and initiatives can indicate, above and beyond creating breast cancer awareness. Our data stem from sources such as printed material, the Internet, and events. From these sources we have singled out and explored objects, text, and visual expressions, looking in particular for metaphors and symbolic aspects. In this article we present six “images” indicating the underlying patterns that we found. We have called the images Re-enchantment of femininity, Infantilization, Corporate profit-making, Objectific…
Cybertherapy meets Facebook, Blogger and Second Life: an Italian experience
2009
Our project is based on the study of Cybertherapy in the international sphere (USA, Northern Europe) and on the application of this discipline to the Italian psychiatric and psychological reality. CyberTherapy can be used as an "aim", referring to it as real and proper therapy, which lives on personalized paths created by a qualified staff, conceived as ludic, for recreational, psycoterapic, and educational purpose. Moreover, Cybertherapy can be used as a "mean" (and in this way we want to propose it) with the aim of making the user, who feels a psychiatric or a psychological uneasiness, to become closer to qualified staff; a considerable advantage of this discipline is to reduce to a minim…
