Social Media Monitoring During Elections: Cases and Best Practice to Inform Electoral Observation Missions

Concern over online interference in elections is now widespread—from the fallout of the Cambridge Analytica scandal to the pernicious effects messaging apps have had in elections in Kenya or Brazil. Yet regulatory and monitoring efforts have lagged behind in addressing the challenges of how public opinion can be manipulated online, and its impact on elections. The phenomenon of online electoral interference is global. It affects established democracies, countries in transition, and places where freedom of expression and access to information are tightly controlled.But fundamental questions of what should be legal and illegal in digital political communication have yet to be answered in order to extend the rule of electoral law from the offline to the online. Answering these questions would help determine the right scope for online election observation, too. This scoping report explains why social media is one of the elements of a democratic, rule of law–based state that observer groups should monitor. It aggregates experience from diverse civil society and nongovernmental initiatives that are innovating in this field, and sets out questions to guide the development of new mandates for election observers. The internet and new digital tools are profoundly reshaping political communication and campaigning. But an independent and authoritative assessment of the impact of these effects is wanting. Election observation organizations need to adapt their mandate and methodology in order to remain relevant and protect the integrity of democratic processes

Toward an Enhanced Mutual Awareness in Asymmetric CVE

International audience—Collaborative Virtual Environments (CVEs) aim at providing several users with a consistent shared virtual world. In this work, we focus on the lack of mutual awareness that may appear in many situations and we evaluate different ways to present the distant user and his actions in the Virtual Environment (VE) in order to understand his perception and cognitive process. Indeed, an efficient collaboration involves not only the good perception of some objects but their meaning too. This second criterion introduces the concept of distant analysis that could be a great help in improving the understanding of distant activities. For this work, we focus on a common case consisting in estimating accurately the time at which a distant user analyzed the meaning of a remotely pointed object. Thus, we conduct some experiments to evaluate the concept and compare different techniques for implementing this new awareness feature in a CVE. Amongst others, results show that expertise of the users influences on how they estimate the distant activity and the type of applied strategies

Manipulating and measuring single atoms in the Maltese cross geometry

Background: Optical microtraps at the focus of high numerical aperture (high-NA) imaging systems enable efficient collection, trapping, detection and manipulation of individual neutral atoms for quantum technology and studies of optical physics associated with super- and sub-radiant states.  The recently developed “Maltese cross” geometry (MCG) atom trap uses four in-vacuum lenses to achieve four-directional high-NA optical coupling to single trapped atoms and small atomic arrays. This article presents the first extensive characterisation of atomic behaviour in a MCG atom trap. Methods: We employ a MCG system optimised for high coupling efficiency and characterise the resulting properties of the trap and trapped atoms.  Using current best practices, we measure occupancy, loading rate, lifetime, temperature, fluorescence anti-bunching and trap frequencies. We also use the four-directional access to implement a new method to map the spatial distribution of collection efficiency from high-NA optics:  we use the two on-trap-axis lenses to produce a 1D optical lattice, the sites of which are stochastically filled and emptied by the trap loading process. The two off-trap-axis lenses are used for imaging and single-mode collection.  Correlations of single-mode and imaging fluorescence signals are then used to map the single-mode collection efficiency.Results: We observe trap characteristics comparable to what has been reported for single-atom traps with one- or two-lens optical systems. The collection efficiency distribution in the axial and transverse directions is directly observed to be in agreement with expected collection efficiency distribution from Gaussian beam optics. Conclusions: The multi-directional high-NA access provided by the Maltese cross geometry enables complex manipulations and measurements not possible in geometries  with fewer  directions of  access,  and can  be  achieved  while  preserving other trap characteristics such as lifetime, temperature, and trap size.Peer ReviewedPostprint (published version

Creativity out of chaos

Creativity is said to be highly desired in post-modern and post-industrial organizations Creativity and anarchy on the one hand, and managerialism, on the other, can be seen as different forms of knowledge, two opposed ideals. In many organizational as well as societal reforms we currently observe it is the managerialist ideal that wins over the anarchic. In this paper, we wonder if people fear anarchy? We reflect on the possible reasons for the fear, and we also try to explain why we believe that anarchic organizing should not be avoided or feared

Minimal invasive ostheosintesis for treatment of diaphiseal transverse humeral shaft fractures

OBJECTIVE:To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique.METHODS:Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures.RESULTS:In two patients, proximal screw loosening occurred, however, the fractures consolidated in the same mean time as the rest of the series. Consolidation with up to 5 degrees of varus occurred in five cases and extension deficit was observed in the patient with olecranon fracture treated with tension band, which was not considered as a complication. There was no recurrence of infection or iatrogenic radial nerve injury.CONCLUSION:It can be concluded that minimally invasive osteosynthesis with bridge plate can be considered a safe and effective option for the treatment of transverse fractures of the humeral shaft.Level of Evidence III, Therapeutic Study.Universidade de Campinas Hospital das Clinicas Department of Orthopedics and TraumatologySwedish Medical CenterUniversidade Federal de São Paulo (UNIFESP) Departament of Orthopedics and TraumatologyUNIFESP, Departament of Orthopedics and TraumatologySciEL

The response of microphytobenthos to physical disturbance, herbicide, and titanium dioxide nanoparticles exposure

The research leading to these results received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 730984, ASSEMBLE Plus project. AJW was funded by the John Templeton Grant 60501, “Putting the Extended Evolutionary Synthesis to the Test”. DMP and AJB were supported by the NERC Blue-coast award (NE/N016009/1).The microphytobenthos that form transient biofilms are important primary producers in intertidal, depositional habitats, yet we have only a limited understanding of how they respond to the cumulative impacts of the growing range of anthropogenic stressors to which they are exposed. We know even less about how the temporal alignment of exposure – such as duration and exposure sequence – may affect the response. Estuarine biofilms were cultured in mesocosms and exposed to the herbicide glyphosate and titanium dioxide (TiO2) nanoparticles in different sequences (glyphosate-first or TiO2-first), as well as in the presence and absence of physical disturbance. We found that at environmentally realistic chemical concentrations, the order of exposure was less important than the total stressor scenario in terms of impacts on key functional attributes and diatom community structure. Physical disturbance did not have an impact on functional attributes, regardless of exposure sequence.Publisher PDFPeer reviewe
