Covid-19 and tracing methodologies: A lesson for the future society

As the new coronavirus (SARS-CoV-2) surged across the globe, new technical solutions have supported policy makers and health authorities to plan and modulate containment measures. The introduction of these solutions provoked a large debate which has focused on risks for privacy and data protection. In this paper we offer an analysis of the available technical approaches and provide new arguments to move beyond the ongoing discussions. In particular, we argue that the past debate missed the opportunity to highlight the societal aspects of privacy and to stimulate a broader reflection on the actions needed to serve the good of society. With this paper, as well as providing an accessible review of the technical and legal aspects of the proposed solutions, we aim to offer new stimuli to reconsider contact tracing and its role in helping countries navigate the current pandemic

Assessment of physical, environmental, and cardiac strain in 43 operators (wearing protective equipment) conducting clean-up of heavy oil products

Background. The aim of the study was to organise an assessment of the physical strains and environmental exposure to hydrocarbon derivatives in persons involved in shoreline clean-up of heavy oil products, in order to investigate the dangers of oil spill clean-up. Material and methods. Forty-three healthy volunteers wearing protective equipment cleaning up an artificial shoreline underwent cardiac strain measurements, as well as a study of thermal stress (approximate WBGT index, water loss, measurement of internal body temperature before and after physical activity). A subjective assessment of perceived exertion was correlated to articular strain indicators recorded for the weight of loads lifted, movement frequency, and the range of movement. Environmental exposure was determined by using portable hydrocarbon detectors. Results. For adult subjects in good physical condition, in neutral temperatures, oil spill clean-up is considered non-arduous. However, in sedentary, stressed subjects exposed to difficult climatic conditions, cleanup can be considered hard to extremely hard. In terms of environmental exposure, slight traces of toluene appeared once out of a total of 18 analysed samples. Conclusions. The sample studied was subject to physical articular strains and presented variable cardiac strain; environmental exposure was, on the other hand, slight when involving cleaning up heavy petroleum products. The subjects liable to carry out this activity are more tolerant to the efforts required when they are healthy, fit, young adults, in the non-arduous thermal conditions recorded in this study

Defending the 'Negro Race': Lamine Senghor and Black Internationalism in Interwar France

This article examines the career of Lamine Senghor, a Senegalese veteran of the First World War, who emerged in the mid 1920s as the most influential black anti-colonial activist of the period. Senghor combined a communist-inspired critique of empire with an attempt to forge a transnational sense of black identity. Many of the questions facing Senghor remain relevant today: should the black community seek equality through its own independent pressure groups or through strategic alliances with mainstream political parties? And how does one engage with issues of racial (or religious) equality within the terms of the purportedly colour-blind and secular Republic

Host and environmental predictors of exhaled breath temperature in the elderly

BACKGROUND: Exhaled breath temperature has been suggested as a new method to detect and monitor pathological processes in the respiratory system. The putative mechanism of this approach is based upon changes in the blood flow. So far potential factors that influence breath temperature have not been studied in the general population. METHODS: The exhaled breath temperature was measured in 151 healthy non-smoking elderly (aged: 60–80 years) at room temperature with the X-halo device with an accuracy of 0.03°C. We related exhaled breath temperature by use of regression models with potential predictors including: host factors (sex, age) and environmental factors (BMI, physical activity, and traffic indicators). RESULTS: Exhaled breath temperature was lower in women than in men and was inversely associated with age, physical activity. BMI and daily average ambient temperature were positively associated with exhaled breath temperature. Independent of the aforementioned covariates, exhaled breath temperature was significantly associated with several traffic indicators. Residential proximity to major road was inversely associated with exhaled breath temperature: doubling the distance to the nearest major intense road was observed a decrease of 0.17°C (95% CI: -0.33 to -0.01; p = 0.036). CONCLUSIONS: Exhaled breath temperature has been suggested as a noninvasive method for the evaluation of airway inflammation. We provide evidence that several factors known to be involved in proinflammatory conditions including BMI, physical activity and residential proximity to traffic affect exhaled breath temperature. In addition, we identified potential confounders that should be taken into account in clinical and epidemiological studies on exhaled breath temperature including sex, age, and ambient temperature

Macrofauna in de verontreinigde waterbodem van de Rijn/Maas-delta

Door middel van monsternemingen en statistische analyses is onderzoek gedaan naar de correlaties tussen fysische variabelen en verontreinigingen (zware metalen, organochloorpesticiden, PCB's, PAK's) in het sediment, de sedimenttoxiciteit bepaald door bioassays, en de variantie in soortensamenstelling van de bodembewonende macrofauna in Brabantsche Biesbosch, Dordtsche Biesbosch, Hollands Diep, Nieuwe Merwede en Haringvlie

Facial expressions depicting compassionate and critical emotions: the development and validation of a new emotional face stimulus set

Attachment with altruistic others requires the ability to appropriately process affiliative and kind facial cues. Yet there is no stimulus set available to investigate such processes. Here, we developed a stimulus set depicting compassionate and critical facial expressions, and validated its effectiveness using well-established visual-probe methodology. In Study 1, 62 participants rated photographs of actors displaying compassionate/kind and critical faces on strength of emotion type. This produced a new stimulus set based on N = 31 actors, whose facial expressions were reliably distinguished as compassionate, critical and neutral. In Study 2, 70 participants completed a visual-probe task measuring attentional orientation to critical and compassionate/kind faces. This revealed that participants lower in self-criticism demonstrated enhanced attention to compassionate/kind faces whereas those higher in self-criticism showed no bias. To sum, the new stimulus set produced interpretable findings using visual-probe methodology and is the first to include higher order, complex positive affect displays
