Political Identities Constructed on a Social Network: The Labour Party on Facebook Boards
2019
This paper is concerned with how an (institutional) political identity is constructed on a Social Network (SN) wall, which represents the political identity of the party as designed in digital interactive contexts, and where political image constructions are eventually accepted or negotiated by the digital audience. Like other political parties, the Labour Party resorts to online platforms for official accounts and political message dissemination (Gerbaudo 2014; Boyd 2014) and constructs its (online) identity. Since interaction is seen (Baumann 2000; De Fina 2011) as the most important locus for the production of identities, this study looks at Facebook boards as interactional sites where t…
Analysis of network rumor dissemination and control mechanisms on Chinese social network : Sina Weibo
2016
The social network has become a major source of information. The openness and swiftness of the network bring instant accessing to both true and false information. Sometimes the false information such as network rumors can mislead people from obtaining the true information and even create chaos. The social network platforms and the governments in different countries are making effort on enacting their own mechanisms to strive on eliminating the rumors. The aim of this thesis is to investigate the spreading of rumors on the Chinese social networking website Sina Weibo. The censorship policy of the Chinese government and the methods used to control the spreading of rumors are discussed. The la…
Du producteur à l'utilisateur: identification des trajectoires d'appropriation des données géographiques.
2009
To define, on a non technician face, the life cycle of geographic information, "from captor to decisions" we need, in a actor network theory perspective, to understand the process "from producer to user". In order to give an answer, we choose to study the spatial data appropriation process. This process opens the analysis of how data can be used by a group that has not produced the data itself, as well as in a multi-actor context. Distributed cognition theory offers a framework to understand data as a cognitive and collaborative artefact. Eight exploratory case studies help to identify typical appropriation trajectories, factors and socio-cognitive processes. This article offers a different…
Distributed optimal power flow for islanded microgrids: An application to the Smart Polygeneration Microgrid of the Genoa University
2016
In this work, the application of an original distributed optimal power flow method to test a microgrid in the Savona area, Italy is proposed. The microgrid shows different types of Distributed Energy Resources (DERs) and is connected to the main grid through a fixed power bus. Due to the high computational speed, the applied distributed Optimal Power Flow can be performed almost in real time, i.e. every 5 minutes or less. The operating solution found for generators, simply using local information, corresponds to a suboptimal condition with reduced losses, bus voltages and line currents within constrained intervals. The distributed optimization algorithm is iterative, but also fast. It is ba…
The role of expert evaluation for microsleep detection
2015
Abstract Recently, it has been shown by overnight driving simulation studies that microsleep density is the only known sleepiness indicator which rapidly increases within a few seconds immediately before sleepiness related crashes. This indicator is based solely on EEG and EOG and subsequent adaptive pattern recognition. Accurate microsleep recognition is very important for the performance of this sleepiness indicator. The question is whether expensive evaluations of microsleep events by a) experts are necessary or b) non-experts provide sufficient evaluations. Based on 11,114 microsleep events in case a) and 12,787 in case b) recognition accuracies were investigated utilizing (i) artificia…
Change Is Good, But Not Too Much: Dynamic Positioning in the Interfirm Network and New Product Development
2018
This research considers the dynamic positioning of an enterprise in an interfirm network and its propensity for new product development. Specifically, we explore how firms reconcile the dichotomy between central and structural holes network positions, by dynamically shifting from a central to a structural holes position (and vice versa) over time. By grounding this research in network dynamics theory, we argue how prior strong central (structural holes) network positions in the interfirm network increase the likelihood the firm will benefit from structural holes (central) positions in the following time period. We also propose that these positions can be modeled by an inverted U-shaped rela…
The upcoming rise of SMEs in cross-border public procurement: is it a matter of networking capabilities?.
2022
La participación de las SME en licitaciones públicas es un tema recurrente en la literatura académica reciente, sin embargo, se ha prestado poca atención a la participación de las PYME en licitaciones internacionales o transfronterizas. Las SME que quieren participar en una licitación pública internacional debe superar barreras internas y externas que difcultan la tarea y minimizan las posibilidades de que le sea concedida la licitación. En este contexto, las capacidades dinámicas son fundamentales para que las PYME puedan enfrentarse y resolver dichas barreras en el contexto internacional. Especialmente son las capacidades de establecer redes las que pueden hacer que las PYME aumenten su d…
Dynamics and extraction of quantum discord in a multipartite open system
2011
We consider a multipartite system consisting of two noninteracting qubits each embedded in a single-mode leaky cavity, in turn connected to an external bosonic reservoir. Initially, we take the two qubits in an entangled state while the cavities and the reservoirs have zero photons. We investigate, in this six-partite quantum system, the transfer of quantum discord from the qubits to the cavities and reservoirs. We show that this transfer occurs also when the cavities are not entangled. Moreover, we discuss how quantum discord can be extracted from the cavities and transferred to distant systems by traveling leaking photons, using the input-output theory.
Using recorded audio feedback in multi-cultural higher e-education : How do academics experience? A thematic network analysis
2020
The aim of our study is to shed light on how academics experience using recorded audio feedback (RAF) as a feedback method in multi-cultural higher e-Education context. We adopted a qualitative content analysis approach, applying thematic network analysis to the data received from three academics (a case study). This approach proposes graphical networks as an aid for analyzing and synthesizing qualitative data into basic, organizing and global themes. The thematic network analysis produced two global, six organizing and 48 basic themes. The two global themes were named “Speaking style” and “Culture neutrality/sensitivity”. Based on our analysis, academics can, by using RAF in multi-cultural…
