Stay with Me: Uncertain Indices and Attentional Presence in Chat Interfaces

In this article, Herrie and Sørensen examine the mediation of typing indicators (“…”) in online messaging. Their point of departure is a scene from the contemporary novel Exciting Times by Naoise Dolan (2020), in which the ‘dots’ play a prominent role. Their analysis shows how typing indicators, as interface design, mediate the complex communication situation in which they take part: from being mere signals, they have slipped into our emotional lives. From a semiotic perspective (Charles S. Peirce), the authors define typing indicators as uncertain indices which through unknowability and suspense establish an attentional presence. In continuation hereof, the authors argue that the acts of writing and waiting in contemporary attentional ecologies (Yves Citton) through the mediation of typing indicators as indicators of attentional presence, could be considered a mode of caring (Bernard Stiegler)

Atopic eczema and cancer: parallel cohort studies in England and Denmark

IMPORTANCE: Associations between atopic eczema and cancer are unclear, with competing theories: that increased immune surveillance reduces cancer risk; and that immune stimulation increases risk. Establishing baseline cancer risk in people with atopic eczema is important prior to exploring the impact of new biologic drugs (for eczema) on cancer risk. OBJECTIVE: To investigate whether atopic eczema is associated with cancer. DESIGN: Matched cohort studies (England: 1998-2016; Denmark: 1982-2016). SETTING: English primary care, and nationwide Danish data. PARTICIPANTS: Individuals with atopic eczema (England: adults only; Denmark: any age) matched on age, sex, calendar period, and (in England only) primary care practice, to people without eczema. EXPOSURE: Atopic eczema MAIN OUTCOMES: We compared overall risk of cancer, and of 11 specific cancers, in people with and without eczema. RESULTS: We included 471,970 and 2,239,775 individuals with and without atopic eczema respectively in England; and 44,945 and 445,673 respectively in Denmark. We found little evidence of associations between atopic eczema and cancer overall (adjusted hazard ratios [HRs] [99%CI]: England 1.04 [1.02-1.06]; Denmark 1.05 [0.95-1.16]), or for most specific cancers. However, non-cutaneous lymphoma risk was raised in people with atopic eczema in England (adjusted HR [99%CI] 1.20 [1.07-1.34] for non-Hodgkin’s [NHL] and 1.48 [1.07-2.04] for Hodgkin’s). Lymphoma risk increased with greater eczema severity (NHL adjusted HR [99%CI] compared to without eczema: mild 1.06 [0.90-1.25], moderate 1.24 [1.04-1.48], severe 2.08 [1.42-3.04]). Danish point estimates also showed increased lymphoma in moderate-to-severe eczema compared to without (adjusted HR [99%CI]: NHL 1.31 [0.76-2.26]; Hodgkin’s 1.35 [0.65-2.28]), but confidence intervals were wide. CONCLUSIONS AND RELEVANCE: Our findings, from two large population-based studies in different settings, are largely reassuring as they do not support associations between eczema and most cancers. However, we observed an association between eczema and lymphoma that increased with eczema severity, which warrants further study with the introduction of new therapeutics that may impact cancer risk

Effect of Manure vs. Fertilizer Inputs on Productivity of Forage Crop Models

Manure produced by livestock activity is a dangerous product capable of causing serious environmental pollution. Agronomic management practices on the use of manure may transform the target from a waste to a resource product. Experiments performed on comparison of manure with standard chemical fertilizers (CF) were studied under a double cropping per year regime (alfalfa, model I; Italian ryegrass-corn, model II; barley-seed sorghum, model III; and horse-bean-silage sorghum, model IV). The total amount of manure applied in the annual forage crops of the model II, III and IV was 158, 140 and 80 m3 ha−1, respectively. The manure applied to soil by broadcast and injection procedure provides an amount of nitrogen equal to that supplied by CF. The effect of manure applications on animal feeding production and biochemical soil characteristics was related to the models. The weather condition and manures and CF showed small interaction among treatments. The number of MFU ha−1 of biomass crop gross product produced in autumn and spring sowing models under manure applications was 11,769, 20,525, 11,342, 21,397 in models I through IV, respectively. The reduction of MFU ha−1 under CF ranges from 10.7% to 13.2% those of the manure models. The effect of manure on organic carbon and total nitrogen of topsoil, compared to model I, stressed the parameters as CF whose amount was higher in models II and III than model IV. In term of percentage the organic carbon and total nitrogen of model I and treatment with manure was reduced by about 18.5 and 21.9% in model II and model III and 8.8 and 6.3% in model IV, respectively. Manure management may substitute CF without reducing gross production and sustainability of cropping systems, thus allowing the opportunity to recycle the waste product for animal forage feeding
