An inclusive case study of multimodal metaphor

Abstract This article provides a detailed analysis of multimodal metaphor by means of a case study which focuses on the contemporary art project, ‘Laboratory of Dilemmas’ (Venetic Biennale 2017), by George Drivas. The analysis focuses on multimodal metaphors which instantiate the source concept of labyrinth, utilizing constructs from Conceptual Metaphor Theory, Critical Metaphor Analysis and Multimodal Metaphor Analysis within a more encompassing framework of Contemporary Art Criticism. The present study aims to define properties of multimodal metaphors, i.e. their forms, concepts and usage, reveal conceptualizations of both the creator and the spectators-analysts of a system of multimodal metaphors, and clarify key contexts, such as embodied, cultural, and ideological, which influence their production, comprehension, impact and analysis. According to the analysis proposed, the multimodal metaphors affect the spectators very deeply, engaging their mental, emotional, multisensory and bodily responses to ideological dilemmas that are prompted by the current refugee migration.

Performance control during longitudinal activation fMRI studies.

The documentation of performance during functional imaging represents a standard procedure employed to control for compliance, sensorimotor, and cognitive demands. In the case of motor tasks, preciseness, force, and frequency have a significant impact on the magnitude of functional activation. Questionnaires are used in psychological investigations to control for cognitive demand, while psychophysiological documentation is employed to record bodily responses. For longitudinal intervention studies, it is of utmost importance to implement meticulous pre- and post-performance controls and balance to accurately assess changes over time. Any changes in compliance may introduce additional uncontrolled variables, which can hinder the interpretation of functional magnetic resonance imaging (fMRI)-related changes. This narrative review presents strategies for controlling and balancing performance in functional imaging approaches to document neuroplasticity in rehabilitative studies. These strategies include not only motor-related aspects, such as precision, velocity, and force, but also timing aspects, such as the start and stop of movement periods. In addition, it discusses strategies for the modulation and control of movement aspects with visual feedback, as well as for the control of physiological changes during experimental modulation. Although these measures require additional care, which is often more demanding than the neuroimaging part of the study, they are crucial for a relevant interpretation and publication of fMRI studies.

Contesting the Prescriptibility of Emotion through Affective Encounters in Lucy Prebble’s The Effect (2012)

This paper explores how Lucy Prebble’s The Effect (2012) dramatises the subversive potentialities of affective encounters as an antidote to the isolating, profit-minded forms of posthumanisation prescribed by modern psychiatry. It argues that the play poignantly unveils how the convergence of the psychopharmaceutical industry with advanced capitalism and neoliberal ideology shape popular discourse around mental illnesses and the necessity of medically induced (self-)regulation of emotion. It also investigates how Prebble mingles crisis with hope in the piece by portraying the autonomy and unpredictability of affective bodily responses, which evade being translated into bio-data and destabilise biopsychiatry’s totalizing view of emotions as utterly controllable through the brain. My analysis utilises Rosi Braidotti’s theorisation of the posthuman subject as both susceptible to exploitation and control and as the site of resistance and ongoing transformation, as presented in her work The Posthuman (2013). It also employs Stefan Herbechter’s theories, as expressed in his book Posthumanism: A Critical Analysis (2013), on how biotechnological developments, advanced capitalism and ideology converge, facilitating new forms of self-governmentality. Finally, it refers to Brian Massumi’s conceptualisation of affect, prevalent in his work “The Autonomy of Affect” (1995) as an intense autonomic bodily response which resists processes of control and manipulation. Ultimately, I argue that The Effect highlights the transformative potential of affective encounters and interconnectedness, functioning as resistance to modern psychiatry’s isolating prescription of emotional self-governance through self-medication.

Sex differences in physiological correlates of affectively driven decision-making behavior in adult ADHD

BackgroundSex differences in the symptomatology of adults with attention-deficit/hyperactivity disorder (ADHD) have often been overlooked when studying behavioral abnormalities. However, it is known that women exhibit considerably more stronger symptoms related to emotional competence than men. Since affective functions significantly influence the processing of risky decision-making and risk-engagement, we assume that risky behavior in ADHD is affected by sex differences. Therefore, we specifically investigated sex-specific effects on the interaction between emotionally induced changes in physiology and behavioral performance on a decision-making task.MethodsSkin conductance responses of twenty-nine adults with ADHD (n = 16 male; n = 13 female) and thirty-three adults in the control group (n = 14 male; n = 19 female) were recorded during the performance in a modified version of the Balloon Analogue Risk Task (BART). Additional questionnaires were used to reveal insights in the self-assessment of emotional competence, risk perception, and feedback sensitivity. Emotional arousal and decision-making behavior were analyzed using linear mixed-effects models.ResultsResults showed different effects of sex on risk behaviors in controls and ADHD. In contrast to healthy controls, female adults with ADHD showed a significantly greater risk engagement in the BART compared to males with ADHD. This contrary sex relation was not observed in skin conductance responses and revealed a significantly different sex-dependent correlation of body response and behavioral task performance in ADHD. Comparisons with results from self-assessments furthermore indicate a reduced behavioral self-perception in women with ADHD, but not in men.ConclusionIn summary, we found an altered interaction between physiological activity and risky behavior in women with ADHD. Thus, the present study indicates a reduced sensitivity towards the own bodily responses in women with ADHD, which could consequently cause increased risky DM behavior in daily life. The current results suggest that more consideration needs to be given to sex-specific effects on physiological processes and behavior in adults with ADHD.

The Effects of Nicotine and Cannabinoids on Cytokines.

The usage of nicotine and cannabinoids has rapidly grown in popularity, leading to increased research into how they can affect people's health, both positively and negatively. Nicotine, Cannabidiol (CBD), and Δ9-tetrahydrocannabinol (THC) have been shown to have significant effects on cytokine function and inflammatory response. This study aimed to review and summarize the current literature on the effects of nicotine and cannabinoids on cytokines, including interleukins, TNF, IFN, and TGF-β. Literature search was conducted on Medline/PubMed electronic databases utilizing the search terms "nicotine" OR "cannabis" OR "cannabinoids" AND "cytokine" AND "inflammation" AND "stress" AND "immune" from 11/1973 to 02/2024. THC and CBD usage have been associated with conflicting impacts on immune response, and observed to both exacerbate and inhibit inflammation. Nicotine has been shown to be generally proinflammatory with regards to cytokines. These responses have been reported to have significant effects on bodily response to inflammation-related diseases. Nicotine usage is associated with worsened outcomes for some conditions, like chronic pain, but improved outcomes for others, like arthritis. The impacts of cannabinoid usage tend to be more positive, exerting anti-inflammatory effects across a wide range of diseases. Given the widespread usage of these substances, it is important to understand the nature of their consequences on immune functions and the underlying mechanisms by which they act. This review has covered how cannabinoids and nicotine affect inflammation directly and how these effects can be attributed to the treatment of inflammatory diseases. In summary, the existing research studying the effects of cannabinoids and nicotine supports the major relationship between nicotine and cannabis use and inflammatory diseases.

Movements that Matter: How Martial Arts Studies Can Reframe the Ethics of First-Blush Empathy

If empathy is how bodies resonate with one another, and ethics is what we are meant to do with that resonance, consideration of the ethics of empathy must begin with the split-second, non-conscious resonance between bodies: first-blush empathy. By combining the expertise of academics and practitioners of bodily knowledge, martial arts studies can distinctively consider how to cultivate the most ethical responses to others. This disciplinary argument takes physical form through a reading of a practice from Shotokan Aiki-karate-do that opposes hyper-attention to self or other with cultivated non-attention. To unpack these principles, the essay then uses philosophy of mind from to illustrate how attention provides a more compelling description of this initial bodily response to other bodies than intention. To most ethically engage others without imposing our own knowledge or self-absorption, we should cultivate deliberate habits of receptivity around first-blush empathy.

Efficacy of multicomponent interventions on injury risk among ice and snow sports participants—a systematic review and meta-analysis

BackgroundIce and snow sports, which are inherently high risk due to their physically demanding nature, pose significant challenges in terms of participant safety. These activities increase the likelihood of injuries, largely due to reduced bodily agility and responsiveness in cold, often unpredictable winter environments. The critical need for effective injury prevention in these sports is emphasized by the considerable impact injuries have on the health of participants, alongside the economic and social costs associated with medical and rehabilitative care. In the context of ice and snow sports environments, applying the E principles of injury prevention to evaluate intervention measures can guide the implementation of future sports safety and other health promotion intervention measures in this field. When well executed, this approach can substantially reduce both the frequency and severity of injuries, thereby significantly enhancing the safety and long-term viability of these challenging sports.ObjectiveThe objective of this study was to rigorously assess and statistically substantiate the efficacy of diverse injury prevention strategies in ice and snow sports, aiming to bolster future safety measures with solid empirical evidence.DesignSystematic review and meta-analysis.MethodsThe overarching aim of this research was to meticulously aggregate and scrutinize a broad spectrum of scholarly literature, focusing on the quantifiable efficacy of diverse, multicomponent intervention strategies in mitigating the incidence of injuries within the realm of ice and snow sports. This endeavour entailed an exhaustive extraction of data from esteemed academic databases, encompassing publications up to September 30, 2023. In pursuit of methodological excellence and analytical rigor, the study employed advanced bias assessment methodologies, notably the AMSTAR 2 and GRADE approaches, alongside sophisticated random-effects statistical modelling. This comprehensive approach was designed to ensure the utmost validity, reliability, and scholarly integrity of the study’s findings.ResultsFifteen papers, including 9 randomized controlled trials, 3 case‒control studies, and 3 cohort studies with 26,123 participants and 4,382 injuries, were analysed. The findings showed a significant reduction in injury rates through various interventions: overall injury prevention (RR = 0.50, 95% CI 0.42–0.63), educational training (RR = 0.50, 95% CI 0.34–0.73), educational videos (RR = 0.53, 95% CI 0.34–0.81), protective equipment (RR = 0.64, 95% CI 0.46–0.87), and policy changes (RR = 0.28, 95% CI 0.16–0.49). Subgroup analysis revealed potential heterogeneity in compliance (p = 0.347). Compared to controls, multicomponent interventions effectively reduced injury rates.ConclusionThis systematic review and meta-analysis demonstrated that multicomponent interventions significantly prevent injuries in ice and snow sports. By applying the E principles of injury prevention and constructing a framework for practical injury prevention research in ice and snow sports, we can gradually shift towards a systemic paradigm for a better understanding of the development and prevention of sports injuries. Moreover, sports injury prevention is a complex and dynamic process. Therefore, high-quality experiments in different scenarios are needed in future research to provide more reliable evidence, offer valuable and relevant prevention information for practitioners and participants, and help formulate more effective preventive measures in practice.

Alcohol effects on interoception shape expectancies and subjective effects: a registered report using the heart rate discrimination task.

Alcohol acutely impacts interoceptive processes, which in turn affect the perception of alcohol effects and the development of alcohol expectancies. However, previous research is limited by the tools used to measure cardiac interoception and subjective alcohol effects. This registered report proposes a re-examination of previous findings using a state-of-the-art measure of interoceptive capacity, the heart rate discrimination task, and measurements of subjective alcohol effects across both ascending and descending limbs. In a double-blind, placebo-controlled experiment, n = 36 participants were given 0.4g/kg of ethanol, and a baseline measure of alcohol expectancies was obtained. Changes in interoceptive capacity after beverage administration, along with measures of light-headedness, mood, and biphasic alcohol effects, were assessed over two sessions. As registered in this secondary data analysis, alcohol was expected to acutely impact different indices of interoceptive capacity, and those changes were hypothesized to correlate with subjective alcohol effects and expectancies. Analyses were conducted only following in-principle acceptance. Alcohol-induced changes in interoceptive capacity predicted the development of light-headedness, stimulation, and negative mood. Changes in interoceptive capacity were also correlated with negative alcohol expectancies, as measured 2 weeks prior to the experiment. These effects were unique to the interoceptive condition, as null effects were observed in an exteroceptive control task. This report offers a replication of key previous findings that alcohol impacts interoceptive processes to shape the detection of subjective alcohol effects. We propose that, through repeated drinking occasions, bodily responses feed into the experience of intoxication, shaping future expectancies about alcohol effects.

Return to reality: What does the world ask of us?

This article introduces the project Return to Reality: What Does the World Ask of Us? This project evolved from a concern that frameworks in mental health operate with knowledge as their primary mode in such a way that reality is lost from sight. This is not primarily an epistemological problem, but an ethical and existential one: ethical because a knowledge-mediated relation to the real can make us blind to the ethical imperatives found in encounters with reality; existential because to be a subject is to respond to what is real. The works of Gert Biesta are a key inspiration. We use Levinas’s, Lingis’s, and Arendt’s ideas to elaborate these concerns. A return to reality is needed; a shift from knowledge-based to reality-sensitive approaches. We relate these ideas to the Open Dialogue approach, with the key imperative of responding to the presence of those present, and to Reflecting team practices, which Tom Andersen describes as being guided by people’s bodily responses.

The civilian's dilemma: Civilians exhibit automatic defensive responses to the police.

Interactions between police officers and civilians incur for both police and civilians the possibility of danger due to a nonzero likelihood of encountering a physical threat. A body of work examining the implications of threat processes during police-civilian interactions focuses almost exclusively on the perspective of police officers, under the auspice that police use-of-force decisions stem from perceptions and misperceptions of threat (e.g., research on the shooter bias). Almost no research has examined these dynamics from the perspective of civilians whose encounter with police involves interacting with an armed and potentially dangerous individual. In the current work, we advance the idea that just as police may respond to civilians as threats, civilians may respond to the police as threats. That is, among civilians, encountering the police may evoke a combination of defensive bodily and behavioral responses. Across three studies (N = 603) each utilizing unique measures of defensive behavioral and physiological responding, we found that people more rapidly avoid police than nonpolice, demonstrate enhanced defensive freeze responses to police than nonpolice, and evince larger defensive physiological preparation toward police than nonpolice. In light of these patterns, we discuss the implications of defensive responses for shaping civilian behavior in real-world encounters with the police.

Aberrant Salience, Psychotic-Like Experiences, and Anxiety: a Case-Control Study

IntroductionIn this research, we investigate how Aberrant Salience (AS), Psychotic-Like Experiences (PLEs), and anxiety are interlinked in both healthy individuals and subjects with psychotic disorders. AS is a trait contributing to a susceptibility to psychosis and anxiety, while PLEs are subclinical states often leading to psychosis. We hypothesize that AS impacts the occurrence and severity of PLEs, which in turn influences anxiety.ObjectivesThe goal is to offer a more nuanced understanding of the risk factors leading to psychotic disorders and to shed light on anxiety psychopathogenesis in healthy and psychotic populations.MethodsWe used self-reported questionnaires like the Aberrant Salience Inventory (ASI), Community Assessment of Psychic Experiences (CAPE), and Symptom Check List-90-revised (SCL-90-R). Data analysis included descriptive statistics and mediation analysis, adjusting for age, gender, and education. Controls were sourced through convenience and snowball sampling, while out-patients diagnosed with Schizophrenia Spectrum Disorder, Bipolar Disorder with psychotic features, or Major Depression with psychotic features were recruited from Florence University Hospital.ResultsA total of 207 participants were included, with 163 controls and 44 patients. Descriptive statistics are shown in Table 1. Mediation analysis showed that PLEs frequency acted as a mediator between AS and anxiety only in the control group (Figure 1), not in patients (Figure 2).Table 1.Descriptive statistics - Mean ± Std.

The discrepancy could be due to reduced novelty and awareness of experiences in the patient group. This may affect how bodily responses to PLEs are perceived and suggests the need for specialized treatment approaches for anxiety in these two groups.Disclosure of InterestNone Declared

Empathy bodyssence: temporal dynamics of sensorimotor and physiological responses and the subjective experience in synchrony with the other's suffering.

Empathy is foundational in our intersubjective interactions, connecting with others across bodily, emotional, and cognitive dimensions. Previous evidence suggests that observing individuals in painful situations elicits whole bodily responses, unveiling the interdependence of the body and empathy. Although the role of the body has been extensively described, the temporal structure of bodily responses and its association with the comprehension of subjective experiences remain unclear. Building upon the enactive approach, our study introduces and examines "bodyssence," a neologism formed from "body" and "essence." Our primary goal is to analyze the temporal dynamics, physiological, and phenomenological elements in synchrony with the experiences of sportspersons suffering physical accidents. Using the empirical 5E approach, a refinement of Varela's neurophenomenological program, we integrated both objective third-person measurements (postural sway, electrodermal response, and heart rate) and first-person descriptions (phenomenological data). Thirty-five participants watched videos of sportspersons experiencing physical accidents during extreme sports practice, as well as neutral videos, while standing on a force platform and wearing electrodermal and heart electrodes. Subsequently, micro-phenomenological interviews were conducted. Bodyssence is composed of three distinct temporal dynamics. Forefeel marks the commencement phase, encapsulating the body's pre-reflective consciousness as participants anticipate impending physical accidents involving extreme sportspersons, manifested through minimal postural movement and high heart rate. Fullfeel, capturing the zenith of empathetic engagement, is defined by profound negative emotions, and significant bodily and kinesthetic sensations, with this stage notably featuring an increase in postural movement alongside a reduction in heart rate. In the Reliefeel phase, participants report a decrease in emotional intensity, feeling a sense of relief, as their postural control starts to reach a state of equilibrium, and heart rate remaining low. Throughout these phases, the level of electrodermal activity consistently remains high. This study through an enactive approach elucidates the temporal attunement of bodily experience to the pain experienced by others. The integration of both first and third-person perspectives through an empirical 5E approach reveals the intricate nature of bodyssence, offering an innovative approach to understanding the dynamic nature of empathy.

Pathological Insights on Polypropylene Mesh Complications From Laparoscopic Sacrocolpopexy: A Case Series.

Background The use of polypropylene mesh in laparoscopic sacrocolpopexy (LSC) is a common treatment for pelvic organ prolapse (POP). Despite its widespread application, postoperative complications such as mesh pain and infection sometimes necessitate the removal of the mesh. However, it remains unclear in which cases mesh removal is warranted. Our research focused on the pathological changes at the sacral fixation point of the mesh. We sought to evaluate the pathological alterations of the sacral mesh removed through an innovative approach of transvaginal natural orifice transluminal endoscopic surgery (vNOTES). Methods This retrospective study included nine patients who underwent mesh removal surgery at the Yokosuka Urogynecology and Urology Clinic in 2023. Extraction surgery was performed using vNOTES with the GelPoint Access Platform (Applied Medical JAPAN HEADQUARTERS, Tokyo, Japan). Non-ablative Erbium YAG and Neodymium YAG lasers (RenovaLase, SP Dynamis; Fotona d.o.o., Ljubljana, Slovenia) were utilized for persistent stress urinary incontinence, fecal incontinence, vaginal erosion, and bleeding after surgery. Patients were categorized based on mesh fixation conditions, including unintended mesh overlap (Group I), excessive traction (Group II), and signs of mesh aging (Group III). This categorization helped to understand the distinct pathological outcomes associated with each condition. Results Pathological findings from the mesh removed via vNOTES varied significantly across the groups. In Group I, characteristic large vacuole formation and accumulation of atypical giant cells were observed, attributed to mesh overlap. Group II presented with vacuole formation, fiber degradation, and tissue destruction as a result of excessive mesh traction. In Group III, the aging of the mesh was marked by cracks in the surrounding tissues and granuloma formation. These detailed observations provide crucial insights into the underlying causes of mesh-related pain and other complications, highlighting the complexity of bodily responses to mesh implants. Conclusion This study demonstrated the effectiveness of vNOTES for polypropylene mesh removal in patients with post-LSC complications, resulting in significant pain reduction. Pathological analysis revealed that mesh-related issues stem from the surgical techniques, mesh properties, and long-term bodily reactions. These findings provide valuable insights for improving mesh design and POP treatment strategies. Despite the technical challenges, vNOTES is recommended for mesh removal in patients with pain. Additionally, the combination of UEL, VEL, targeted laser irradiation, AEL, and Nd:YAG laser treatments showed promising results in managing post-mesh removal complications such as stress urinary incontinence, vaginal erosion, bleeding, and fecal incontinence, offering hope for improved patient outcomes.

Physiological Synchrony During Partnered Sexual Activity

Physiological synchrony (PS) refers to the coordination of bodily responses in close relationships. It seems to be linked to relational well-being, satisfaction, closeness, and empathy. Recent research extends these findings to sexual relationships as well, with evidence suggesting that PS may predict attraction and sexual satisfaction. The current study focuses on PS during sexual activity within established couples. Results suggest that PS develops during sexual activity, in certain contexts, and tends to be greater in magnitude during sexual encounters than during non-sexual interactions. Results may shed light on the dyadic psychophysiological factors relevant to sexual experiences.

Exploring students’ immersive VR experiences as resources for collaborative meaning making and learning

By adopting a situated and interactional approach, we explore students’ immersive VR experiences as resources for collaborative meaning making and learning. We draw on data from a project in which teachers and researchers co-developed a learning design for upper secondary students involving immersive VR technology. In this learning design, students viewed a cinematic VR film where they encountered different people telling personal stories about exclusion and discrimination, followed by reflective group dialogues with their teacher about their experiences in this environment. Through a detailed interaction analysis of these dialogues, we identify four dimensions that characterize students’ meaning making: (1) the feeling of taking part in conversations, (2) attending to bodily expressions of others, (3) students’ own bodily responses, (4) teacher guidance. We discuss how the findings from our analysis contribute to the field of CSCL, and which also have implications for instructional work that includes the use of immersive VR environments.

Unraveling Links between Chronic Inflammation and Long COVID: Workshop Report.

As COVID-19 continues, an increasing number of patients develop long COVID symptoms varying in severity that last for weeks, months, or longer. Symptoms commonly include lingering loss of smell and taste, hearing loss, extreme fatigue, and "brain fog." Still, persistent cardiovascular and respiratory problems, muscle weakness, and neurologic issues have also been documented. A major problem is the lack of clear guidelines for diagnosing long COVID. Although some studies suggest that long COVID is due to prolonged inflammation after SARS-CoV-2 infection, the underlying mechanisms remain unclear. The broad range of COVID-19's bodily effects and responses after initial viral infection are also poorly understood. This workshop brought together multidisciplinary experts to showcase and discuss the latest research on long COVID and chronic inflammation that might be associated with the persistent sequelae following COVID-19 infection.

Neuroimaging-based evidence for sympathetic correlation between brain activity and peripheral vasomotion during pain anticipation

Anticipation of pain engenders anxiety and fear, potentially shaping pain perception and governing bodily responses such as peripheral vasomotion through the sympathetic nervous system (SNS). Sympathetic innervation of vascular tone during pain perception has been quantified using a peripheral arterial stiffness index; however, its innervation role during pain anticipation remains unclear. This paper reports on a neuroimaging-based study designed to investigate the responsivity and attribution of the index at different levels of anticipatory anxiety and pain perception. The index was measured in a functional magnetic resonance imaging experiment that randomly combined three visual anticipation cues and painful stimuli of two intensities. The peripheral and cerebral responses to pain anticipation and perception were quantified to corroborate bodily responsivity, and their temporal correlation was also assessed to identify the response attribution of the index. Contrasting with the high responsivity across levels of pain sensation, a low responsivity of the index across levels of anticipatory anxiety revealed its specificity across pain experiences. Discrepancies between the effects of perception and anticipation were validated across regions and levels of brain activity, providing a brain basis for peripheral response specificity. The index was also characterized by a 1-s lag in both anticipation and perception of pain, implying top-down innervation of the periphery. Our findings suggest that the SNS responds to pain in an emotion-specific and sensation-unbiased manner, thus enabling an early assessment of individual pain perception using this index. This study integrates peripheral and cerebral hemodynamic responses toward a comprehensive understanding of bodily responses to pain.

Altered emotional mind-body coherence in older adults.

Coherence between subjective experience and bodily responses in emotion is assumed to have a positive influence on well-being, which might be particularly valuable in late adulthood. Previous studies of young adults' continuous subjective, behavioral, and physiological responses to emotional films reported emotional mind-body coherence. In contrast, research regarding emotional coherence in older adults has been scarce. In this study, we examined emotional coherence in older adults between continuous valence ratings and behavioral responses (facial electromyography [EMG] of the corrugator supercilii and zygomatic major muscles), as well as between continuous arousal ratings and physiological measures (electrodermal activity [EDA] and fingertip temperature), in response to four emotion-eliciting film clips (anger, sadness, contentment, and amusement) film clips and an emotionally neutral clip. Intraindividual cross-correlation analyses revealed that the coherence between valence ratings and corrugator EMG activity for the anger-eliciting film was weaker in older adults than in young adults, who completed an identical experiment. Age differences also emerged in the coherence of arousal ratings with EDA and fingertip temperature measures, respectively, while participants watched the anger-eliciting and contentment-eliciting films; while negative correlations were found for older adults, positive correlations were found for young adults. These results indicate that emotional mind-body coherence somewhat differs quantitatively and qualitatively between older and young adults.

Время — вперед: необратимость события, аффект и нарративы будущего

Contemporary fiction and film are full of complex narrative forms. They attempt to make readers’ and viewers’ experience more perplexed, while also challenging and redefining the basic elements of narrative. The forking-path narrative also highlights the complexity of contemporary narrative forms: it presents a storyworld which encompasses multiple possible alternative worlds. Events within it can be either reversible or irreversible, and each time they remain unpredictable to the reader. The author examines the irreversibility of events in forking-path narratives on the example of the Paul Auster’s novel 4321. While reversibility of events emphasizes that the fabula can be changed in each storyline and, as a result, it becomes multiversion, irreversibility of events instead has a different effect. Irreversible events operate in forking-path narratives on the principle of repetition: they invariably recur in each storyline, and this recurrence enhances (more frequently a tragic) experience. The recurrence of irreversible events also creates a specific rhythm within the narrative. Such rhythmic patterns emerge at the narrative level and have a major role in shaping the reader’s experience, requiring bodily response, i.e. potentially resulting in bodily feelings. It constructs a mimesis which can be understood as “carnal” (in terms of Vivian Sobchack), with less mediation between storyworld and reader reality. The experience generated by irreversible events conflicts with another, shaped by reversible events, and together they generate the effect of a chaotic temporal movement, typical for narratives that can be regarded as “unruly” and “extreme,” with a versatile (and simultaneous) impact on the reader.

Information theory reveals physiological manifestations of COVID-19 that correlate with symptom density of illness.

Algorithms for the detection of COVID-19 illness from wearable sensor devices tend to implicitly treat the disease as causing a stereotyped (and therefore recognizable) deviation from healthy physiology. In contrast, a substantial diversity of bodily responses to SARS-CoV-2 infection have been reported in the clinical milieu. This raises the question of how to characterize the diversity of illness manifestations, and whether such characterization could reveal meaningful relationships across different illness manifestations. Here, we present a framework motivated by information theory to generate quantified maps of illness presentation, which we term "manifestations," as resolved by continuous physiological data from a wearable device (Oura Ring). We test this framework on five physiological data streams (heart rate, heart rate variability, respiratory rate, metabolic activity, and sleep temperature) assessed at the time of reported illness onset in a previously reported COVID-19-positive cohort (N = 73). We find that the number of distinct manifestations are few in this cohort, compared to the space of all possible manifestations. In addition, manifestation frequency correlates with the rough number of symptoms reported by a given individual, over a several-day period prior to their imputed onset of illness. These findings suggest that information-theoretic approaches can be used to sort COVID-19 illness manifestations into types with real-world value. This proof of concept supports the use of information-theoretic approaches to map illness manifestations from continuous physiological data. Such approaches could likely inform algorithm design and real-time treatment decisions if developed on large, diverse samples.
