This machine kills fascists : detecting propaganda with formal models of mass discourse structure (and other ideas)

This dissertation consists of three free-standing chapters, all of which deal with themes in the philosophy of language in general and in pragmatics in particular. Chapter 1 augments an existing model of discourse-level information structure in order to articulate relevance conditions that make the right predictions about the class of utterances I call higher order utterances. The apparatus introduced turns out also to have some utility for the representation of a certain kind of discourse defectiveness. Chapter 2 explores an analogy between communication and knowledge to ultimately advance the thesis that communication is not a uniquely valuable type of signaling event. Chapter 3 draws connections between propaganda and polarization, and then between the measurement of polarization and the tools used in the modeling of discourse structure. The upshot is that tools from formal pragmatics have an application in the characterization, and perhaps ultimately detection, of propaganda.Philosoph

Luck and the Value of Communication

Those in the Gricean tradition take it that successful human communication features an audience who not only arrives at the intended content of the signal, but also recognizes the speaker’s intention that they do so. Some in this tradition have also argued that there are yet further conditions on communicative success, which rule out the possibility of communicating by luck. Supposing that both intention-recognition and some sort of anti-luck condition are correctly included in an analysis of human communication, this article asks what the value of events satisfying these conditions is. I present a puzzle concerning the value of intention-recognition which is analogous to the Meno Problem in epistemology, but ultimately argue that this puzzle is solveable: the signaling-relevant value of intention recognition can be vindicated. However, I argue that the version of this puzzle that concerns the further proposed luck-proofing conditions on communication can not be answered. I argue therefore that communication, as analyzed by many, is no more valuable qua signal than a proper subset of its conditions. Human communication is thennot a uniquely valuable signaling event

Propaganda, Irrationality, and Group Agency

I argue that propaganda does not characteristically interfere with individual rationality, but instead with group agency. Whereas it is often claimed that propaganda involves some sort of incitement to irrationality, I show that this is neither necessary nor sufficient for a case’s being one or propaganda. For instance, some propaganda constitutes evidence of the speaker’s power, or else of the risk and futility of opposing them, and there is nothing irrational about taking such evidence seriously. I outline an alternative account of propaganda inspired by Hannah Arendt, on which propaganda characteristically creates or destroys group agency. One aspiring to control the public should have an interest in both creating and suppressing group agency, I argue, both because groups have capacities that individuals don’t, and because participation in group action can have a transformative effect upon the individual. Finally, I suggest that my characterization of propaganda suggests a vision of resistance to propaganda quite unlike the one that emerges from irrational-belief accounts, on which propaganda cannot be resisted by oneself

Deepfakes, Public Announcements, and Political Mobilization

This paper takes up the question of how videographic public announcements (VPAs)---i.e. videos that a wide swath of the public sees and knows that everyone else can see too--- have functioned to mobilize people politically, and how the presence of deepfakes in our information environment stands to change the dynamics of this mobilization. Existing work by Regina Rini, Don Fallis and others has focused on the ways that deepfakes might interrupt our acquisition of first-order knowledge through videos. But I point out that even where every audience member takes a video to be veridical, where first-order knowledge acquisition is secure, an audience aware of deepfakes in their environment will not acquire higher order knowledge in the way that has erstwhile been characteristic for audiences of VPAs. Engaging with ideas from the literatures on public announcement logic, common knowledge, and convention, I enumerate a variety of ways in which we should expect this absence of higher order knowledge to throw up barriers to political mobilization. I go on to apply my analysis of VPAs to the mechanisms by which an uptick in publicly available videos of police brutality over the last decade, mediated by camera phones and social media, was responsible for the largest mass protests in US history in summer 2020. This makes vivid the stakes of the transformation in our mobilizing environment that I've claimed deepfakes effect: where we lose the common-knowledge-generating effects of VPAs, there are fresh obstacles to this sort of mass mobilization

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
