Hpdm : A Hybrid Pseudonym Distribution Method for Vehicular Ad-Hoc Networks
2016
Abstract Protecting the location privacy of drivers is still one of the main challenges in Vehicular Ad-hoc Networks (VANETs). The changing of pseudonym is commonly accepted as a solution to this problem. The pseudonyms represent fake vehicle identifiers. Roadside Units (RSUs) play a central role in the existing pseudonyms distribution solutions. Indeed, the VANET area should totally be covered by RSUs in order to satisfy the demand of vehicles in terms of pseudonyms. However, the total coverage is costly and hard to be achieved, especially in the first phase of VANETs deployment. In addition, RSUs could be overloaded due to the large number of pseudonyms requests that could be received fro…
Role of particle characteristics in the compression behaviour of gap-graded sands
2019
Abstract The compression in gap-graded mixtures of sands with combined mineralogy has been investigated in recent research, focusing on the key factors that might imply the occurrence of convergent or non-convergent paths in compression (i.e., transitional or non-transitional behaviour). From previous work, the mineralogy of a matrix composed of larger grains seems to determine the possibility of the occurrence of transitional behaviour. Hence, if there is a strong and stiff matrix made of quartz sand particles, which are either larger than or at least of similar size to the other component, then non-convergent compression paths (i.e., transitional behaviour) are likely to occur. As a furth…
Bacterial community structure along the subtidal sandy sediment belt of a high Arctic fjord (Kongsfjorden, Svalbard Islands)
2018
Open fjords are subject to contrasting environmental conditions, owing to meltwater glacial inputs, terrestrial runoff, and marine water mass exchanges, which are exacerbated by anthropogenic and climate perturbations. Following a slope-dependent water circulation, the subtidal sandy sediment belt regulates the convergent transport of nutrients downward the fjord depths, and the effective entrapment of suspended particles and microorganisms. In this study, we aimed at testing how glacial and seawater inputs may influence the bacterial community structure of subtidal sand deposits in the Kongsfjorden. Through total and viable cell counting and an amplicon sequencing approach, we found releva…
A Review of the State-of-the-Art of Assistive Technology for People with ASD in the Workplace and in Everyday Life
2019
Part 8: Digital Divide and Social Inclusion; International audience; Autism, also known as autism spectrum disorder (ASD), is an incurable brain-based disorder that refers to a wide range of complex neurodevelopment disorders characterised by marked difficulties in communication and social skills, repetitive behaviour, highly focused interests and sensory sensitivity. Autism can present challenges for affected people at the work environment and in everyday life. The barrier for individuals with ASD increases further with changing environmental situations. Individuals with ASD have limited abilities to isolate their Five senses and often experience over- or under-sensitivity to sounds, touch…
Sexist attitudes, romantic myths, and offline dating violence as predictors of cyber dating violence perpetration in adolescents
2020
Abstract The objectives of this study were to analyze the prevalence of cyber dating violence perpetration (cyber-control and cyber-aggression) in adolescent boys and girls, and to explore the relations between adolescents’ involvement in cyber dating violence perpetration (never, occasional, and frequent) and their sexist attitudes (hostile and benevolent), romantic myths, and offline dating violence perpetration (relational, physical, and verbal-emotional). The predictive weight of these variables in relation to cyber dating violence perpetration (cyber-control and cyber-aggression) was also analyzed. Of an initial sample of 919 adolescents, who had or had had a dating relationship in the…
Reflections on the Significance of Images in Genocide Studies: Some Methodological Considerations
2018
Social practices such as massacres, mass violence and the extermination of entire populations are not a historical novelty. Indeed, when Raphael Lemkin coined the term genocide in 1944 he was but giving a new name to an old crime.1 Such phenomena have been witnessed by humanity since Ancient times and historians, as well as artists and writers, have utilized every tool at their disposal to find ways to depict them and impress upon their audience the impact they had. Insofar as these are extreme phenomena that challenge the very notion of our humanity, such events inevitably test as well the limits of representation. Eyewitness accounts, historical narrations, philosophical observations, and…
Creativity and Innovation in Technology-Mediated Journalistic Work : Mapping out Enablers and Constraints
2020
This qualitative study examines creativity and innovation in dispersed, journalistic teams. Specifically, we study the factors enabling and constraining creativity and innovation in journalistic work in technology-mediated settings and explore how technology shapes these phenomena in dispersed journalistic teams. The study is motivated by the media industry’s heightened need for creativity and innovation as well as the changing nature of working life where an increasing amount of work is done via information and communication technologies. By closely examining two journalistic teams and their idea sharing and development processes, this study finds that successful creative work and innovati…

Through this brief work we reflect on freedom of expression and the criminalization of lies at a time when fake news has gained prominence
A COLAB model Of workplace transformation in the criminal justice context
2021
AbstractThis chapter presents the COLAB model for promoting organisational learning and innovation with potential application in criminal justice-related organisations. We describe this model as a toolkit that built on the Change Laboratory model of workplace transformation but one augmented with the beneficial components of Activity Clinics, Boundary Crossing Workshops and Codesign methods and developed within the criminal justice context. Limitations and future directions for the model are discussed.
The Relevance of Mineral Mobilization and -Dissolution on the Reservoir Quality of Sandstones in CO2 Storage Sites
2014
Abstract Rotliegend siliciclastic formations are important reservoirs in central Europe. These sediments consist of pristine red coloured and bleached, high porous and permeable sandstones. To evaluate the relevance of distinct fluids and their fluid-rock alteration reactions on such bleaching processes laboratory static batch experiments under reservoir conditions were conducted. Thereby mineralogical, petrophysical and (hydro-, geo-) chemical rock features were investigated by different analytical methods before and after the experiments. The achieved results suggest that during such fluid-rock interactions a complex interplay between mineral detachment and mineral dissolution processes w…
