Computational Propaganda: Targeted Advertising and the Perception of Truth

Social media has become an effective medium for the execution of cyberpsychological threats by adopting language to influence perceptions based on personal interests and behaviours. Targeted messages can be refined for maximum effect and have been implicated in changing the outcome of democratic elections and the decreasing uptake of vaccinations. However, computational propaganda and cyberpsychological threats are not well understood within the cybersecurity community. To address this, we adopt the theoretical model of the illusory truth effect to posit that how information is presented online, may solidify views in an \u27undecided\u27 group with \u27some\u27 knowledge of an argument. We test this hypothesis by employing an explanatory sequential design. We first analyse a dataset containing adverts related to Brexit to determine influential terms using the corpus linguistics method. Analysing term frequencies, collocational and concordance information, the results of our quantitative analysis indicate that function words such as the personal pronouns ‘we’ or the definite article ‘the’ play a significant role in the construction of computational propaganda language. We then conducta qualitative analysis of a Facebook ad related to Brexit to further understand how the ‘who’ and the ‘what’ elements are realised in computational propaganda language, that is, who is targeted and what is the underlying message. We found that understanding these, one can gain insights into a threat actor’s motivation, opportunity and capability and, thus, allows a defensive response to be put into place. In turn, how an audience responds, may provide insight on the impact of the threat

Human immunodeficiency virus type 1 envelope-mediated neuropathogenesis: targeted gene delivery by a Sindbis virus expression vector

AbstractSindbis virus (SIN) expression vectors offer the opportunity for studying neuropathogenesis because of their distinct neural cell tropism. Here, we demonstrate that a recombinant SIN vector expressing EGFP (SINrep5-EGFP) infected multiple cell types including neural cells from several species relevant to lentivirus pathogenesis with high levels of transgene expression. Infection of human neurons by a recombinant SIN (SINrep5-JRFL) expressing the full-length envelope from a neurovirulent human immunodeficiency virus type 1 (HIV-1) strain (JRFL) caused increased cytotoxicity compared to infection with SINrep5-EGFP (P < 0.001), while no cytotoxicity was observed among infected human astrocytes or monocytoid cells. Both human monocyte-derived macrophages (MDM) (P < 0.01) and astrocytes (P < 0.001) infected with SINrep5-JRFL released soluble neurotoxins in contrast to SINrep5-EGFP or mock-infected cells, although this was most prominent for the astrocytes. Implantation of SINrep5-JRFL into the brains of SCID/NOD mice induced neuroinflammation, neuronal loss, and neurobehavioral changes characteristic of HIV-1 infection, which were not present in SINrep5-EGFP or mock-infected animals. Thus SIN expression vectors represent novel tools for studying in vitro and in vivo HIV-1 neuropathogenesis because of their high levels of transgene expression in specific cell types within the brain

The development of a marker system for Pharmacists' Behavioural Skills

Objectives: Pharmacists increasingly require complex behavioural skills to fulfil enhanced roles within healthcare teams. Behavioural marker systems are used to assess behavioural (or non-technical) skills during immersive simulation. This study aimed to develop a marker system for pharmacists' behavioural skills in patient-focussed care scenarios, and to investigate its content validity. Methods: Literature describing existing marker systems and the requisite behavioural skills of pharmacists were presented to two expert panels, alongside video examples of pharmacists in patient-focussed care simulations. The expert panels used this information to develop a new behavioural marker system. A third expert panel assessed the content validity, and the item- and scale-content validity indices were calculated. Key findings: The resulting tool contains four categories, each with three or four skill elements: situation awareness (gathering information; recognising and understanding information; anticipating, preparing and planning), decision-making and prioritisation (identifying options; prioritising; dealing with uncertainty; implementing or reviewing decisions), collaborative working (involving the patient; information sharing; leadership or followership), self-awareness (role awareness; speaking up; escalating care; coping with stress). The scale-content validity index was 0.95 (ideal) and the only item below the acceptable cut-off was 'leadership or followership' (0.7). Conclusions: This tool is the first marker system designed to assess the behavioural skills of pharmacists in patient-focussed care scenarios. There is evidence of good content validity. It is hoped that once validated, the Pharmacists' Behavioural Skills marker system will enable pharmacy educators to provide individualised and meaningful feedback on simulation participants' behavioural skills.</p

Perceived Versus Performance Fatigability in Patients With Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic, inflammatory disease that affects 1% of the general population. Fatigue is a common complaint of patients with RA, however their perceived fatigue may be more exacerbated than objective measures of fatigue may indicate. The assessment of fatigue is made complex due to inconsistent and vague terms used to define fatigue, and the task dependence of fatigability. Fatigue is defined as a state of exhaustion and decreased strength, while fatigability indicates an individual’s susceptibility to fatigue. In order to offer some clarity to the manifestation of fatigue in clinical populations, in this review we outline that fatigue should be described with subsections that are related to the symptom, such as: perceived fatigability and performance fatigability. Where perceived fatigability indicates the subjective state of the individual and thus involves the individual’s subjective measure of fatigue, performance fatigability would be measured through clinical and laboratory-based assessments that quantify the functional decline in performance. This review describes RA and the various neuromuscular changes associated with the disease that can lead to alterations in both perceived and performance fatigue. From there, we discuss fatigue and RA, how fatigue can be assessed, effects of exercise interventions on RA symptoms and fatigue, and recommendations for future studies investigating subjective and objective measures of fatigability

Disability, ICT and eLearning Platforms: Faculty-Facing Embedded Work Tools in Learning Management Systems

This paper contributes to the current discussion in the field of human-computer interaction design (HCI) on the accessibility and design of eLearning tools embedded in the online platforms for higher education. Presenting the preliminary results of a longitudinal study of the accessibility of the faculty-facing pages of Canvas learning management system, it aims at drawing the attention of designers, developers, and manufacturers to the barriers erected by the ableist LMS designs for disabled faculty. The paper asks for improvements in design processes by embracing participatory design methods and by paying attention to the recommendations included in this paper

Computable phenotype for real-world, data-driven retrospective identification of relapse in ANCA-associated vasculitis

Objective: ANCA-associated vasculitis (AAV) is a relapsing-remitting disease, resulting in incremental tissue injury. The gold-standard relapse definition (Birmingham Vasculitis Activity Score, BVAS>0) is often missing or inaccurate in registry settings, leading to errors in ascertainment of this key outcome. We sought to create a computable phenotype (CP) to automate retrospective identification of relapse using real-world data in the research setting.Methods: We studied 536 patients with AAV and >6 months follow-up recruited to the Rare Kidney Disease registry (a national longitudinal, multicentre cohort study). We followed five steps: (1) independent encounter adjudication using primary medical records to assign the ground truth, (2) selection of data elements (DEs), (3) CP development using multilevel regression modelling, (4) internal validation and (5) development of additional models to handle missingness. Cut-points were determined by maximising the F1-score. We developed a web application for CP implementation, which outputs an individualised probability of relapse.Results: Development and validation datasets comprised 1209 and 377 encounters, respectively. After classifying encounters with diagnostic histopathology as relapse, we identified five key DEs; DE1: change in ANCA level, DE2: suggestive blood/urine tests, DE3: suggestive imaging, DE4: immunosuppression status, DE5: immunosuppression change. F1-score, sensitivity and specificity were 0.85 (95% CI 0.77 to 0.92), 0.89 (95% CI 0.80 to 0.99) and 0.96 (95% CI 0.93 to 0.99), respectively. Where DE5 was missing, DE2 plus either DE1/DE3 were required to match the accuracy of BVAS.Conclusions: This CP accurately quantifies the individualised probability of relapse in AAV retrospectively, using objective, readily accessible registry data. This framework could be leveraged for other outcomes and relapsing diseases.Keywords: Classification; Epidemiology; Outcome Assessment, Health Care; Vasculitis
