Brand impact on purchase intention. An approach in social networks channel

2012

Networks are an exciting new channel that brands should use for promoting a more participatory and proactive context with a user, increasingly elusive and restrictive, that takes decisions based on the impulses generated by networkers. We propose a model adapted to the reality studied and composed by several models and theories that have got widespread support in the literature. In this paper, the goal is threefold, in response to a consumer perspective: (i) measuring the efficiency, in social networks, of the constructs selected  regarding the attitude towards network and the intention to use, (ii) measuring the influence of attitude toward the net in the attitude toward the brand in terms…

Too much information!? Examining the impact of different levels of transparency on consumers’ evaluations of targeted advertising

2019

Online behavioral advertising is widely employed across the Internet. To mitigate the lack of transparency in tailored advertising and increase the acceptance of behavioral advertising, numerous pl...

While previous communication and media research has largely focused on either studying privacy as personal boundary management or made efforts to investigate the structural (legal or economic) condition of privacy, we observe an emergent body of research on the political underpinnings of privacy linking both aspects. A pronounced understanding of the politics of privacy is however lacking. In this contribution, we set out to push this forward by mapping four communication and media perspectives on the political implications of privacy. In order to do so, we recur on Barry’s (2002) distinction of the political and the politics and outline linkages between individual and structural dimensions…

Normalization 2.0: A longitudinal analysis of German online campaigns in the national elections 2002–9

2011

This article examines the functional, relational and discursive dimensions of the normalization thesis in one study, for both Web 1.0 and Web 2.0 features, in a longitudinal design. It is based on a quantitative content and structural analysis of German party websites in the national elections between 2002 and 2009. The results show that the normalization thesis holds true in all its dimensions over time and in the Web 2.0 era: parties still focus on the top-down elements of information provision and delivery while interactive options are scarce. The digital divide between parliamentary and non-parliamentary parties has narrowed over time, but remains visible for all online functions in 200…

Current debates on online privacy are rooted in liberal theory. Accordingly, privacy is often regarded as a form of freedom from social, economic, and institutional influences. Such a negative perspective on privacy, however, focuses too much on how individuals can be protected or can protect themselves, instead of challenging the necessity of protection itself. In this article, I argue that increasing online privacy literacy not only empowers individuals to achieve (a necessarily limited) form of negative privacy, but has the potential to facilitate a privacy deliberation process in which individuals become agents of social change that could lead to conditions of positive privacy and infor…

Design and implementation of a long-range low-power wake-up radio and customized DC-MAC protocol for LoRaWAN

2019

In this paper, we present the design and implementation of a long-rage wake-up radio (WuR) and customized duty cycled (DC) MAC protocol for wireless IoT devices. The WuRx achieves a sensivity of −70 dBm by consuming just 0.032 mA, thereby optimizing the energy consumption of battery powered long-range wireless IoT devices. Reducing the power consumption of these devices minimizes the overall costs when deployed in large scale.

An Ontology Model for Interoperability and Multi-organization Data Exchange

2020

Progress in the uptake and use of technologies such as Artificial Intelligence and the Internet of Things seems to be stalled by the colossal fragmentation of information and data standards. This complexity is compounded by issues of inter-organisational differences, hindering effective collaboration. There is a growing demand for cross-organizational integrations in regulated but decentralized environments. This paper introduces an ontology architecture where information is sliced into independent semantic layers, each focusing on a specific aspect of the data. By dissolving traditional monolithic data structures into layered, light semantic components, the necessity to maintain contextual…

Anomaly‐based intrusion detection systems: The requirements, methods, measurements, and datasets

2021

International audience; With the Internet's unprecedented growth and nations' reliance on computer networks, new cyber‐attacks are created every day as means for achieving financial gain, imposing political agendas, and developing cyberwarfare arsenals. Network security is thus acquiring increasing attention among researchers, practitioners, network architects, policy makers, and others. To defend organizations' networks from existing, foreseen, and future threats, intrusion detection systems (IDSs) are becoming a must. Existing surveys on anomaly‐based IDS (AIDS) focus on specific components such as detection mechanisms and lack many others. In contrast to existing surveys, this article co…

Optimization of the Relay Selection Scheme in Cooperative Retransmission Networks

2011

Cooperative MAC protocol design has attracted much attention recently thanks to the development of relaying techniques. In single-relay C-ARQ, the relay selection scheme cannot work efficiently in a dense network, due to high collision probability among different contending relays. In this paper, the throughput performance impairment from the collision is analysed in a typical network scenario. Thereby, we propose an optimized relay selection scheme aiming at maximizing system throughput by reducing collision probability. The throughput performance enhancement by the proposed optimal relay selection scheme is verified by simulations.

Big Data Metadata Management in Smart Grids

2014

Smart home, smart grids, smart museum, smart cities, etc. are making the vision for living in smart environments come true. These smart environments are built based upon the Internet of Things paradigm where many devices and applications are involved. In these environments, data are collected from various sources in diverse formats. The data are then processed by different intelligent systems with the purpose of providing efficient system planning, power delivery, and customer operations. Even though there are known technologies for most of these smart environments, putting them together to make intelligent and context-aware systems is not an easy task. The reason is that there are semantic…
