‘Sorry everything’s in bags’: The accountability of selling bread at a market during the COVID-19 pandemic

Societies are undergoing enormous upheavals in the wake of the COVID-19 pandemic. High levels of psychological distress are widespread, yet little is known about the exact impacts at the micro-level of everyday life. The present study examines the ordinary activity of buying bread to understand changes occurring early in the crisis. A dataset of over 50 social interactions at a community market stall were video-recorded, transcribed and examined in detail using multi-modal conversation analysis. With COVID-19 came an orientation to a heightened risk of disease transmission when selling food. The bread was placed in bags, a difference which was justified as a preventative measure and morally normalised by invoking a common-sense prohibition of touching produce. Having the bread out of immediate sight was a practical challenge that occasioned the expansion of turns and sequences to look for and/or confirm what was for sale, highlighting a normative organisation between seeing and buying. The analysis shows how a preventative measure related to the pandemic was adjusted to interactionally. More broadly, this research reveals the small changes to daily life that likely contribute to the overall negative impacts on health and well-being that have been reported.

Impact of a Neck Strap Intervention on Perceived Effort, Thumb Force, and Muscle Activity of Clarinetists

OBJECTIVE: Clarinetists often report discomfort of the right wrist and thumb and note that it is likely the result of the constant force applied to the area from the instrument’s weight and the musician’s technique. One preventative measure to reduce this discomfort is the use of a neck strap. The objective of the current study was to document the biomechanical impacts of this intervention. METHODS: Eight experienced clarinetists played a series of three etude pieces while playing both with and without a neck strap. For each condition, the force between the right thumb and clarinet was measured, electromyographic (EMG) data were collected from seven muscle groups, and subjective assessment of perceived effort was obtained. RESULTS: The results showed that when the neck strap was used, there was a significant decrease in the average force between the thumb and clarinet (p<0.05) and a decrease in the average perceived effort required for the right shoulder and thumb of the participants (p<0.05). Importantly, there were no statistically significant increases in the muscle activity of any of the neck and shoulder muscles with the introduction of the neck strap intervention. CONCLUSION: A neck strap intervention had positive effects on the right thumb while not causing any known adverse effects to other areas such as the neck, upper back, and shoulders.

Vaccination as a preventative measure contributing to immune fitness

The primary goal of vaccination is the prevention of pathogen-specific infection. The indirect consequences may include maintenance of homeostasis through prevention of infection-induced complications; trained immunity that re-programs innate cells to respond more efficiently to later, unrelated threats; slowing or reversing immune senescence by altering the epigenetic clock, and leveraging the pool of memory B and T cells to improve responses to new infections. Vaccines may exploit the plasticity of the immune system to drive longer-term immune responses that promote health at a broader level than just the prevention of single, specific infections. In this perspective, we discuss the concept of “immune fitness” and how to potentially build a resilient immune system that could contribute to better health. We argue that vaccines may contribute positively to immune fitness in ways that are only beginning to be understood, and that life-course vaccination is a fundamental tool for achieving healthy aging.

Pandemic, but Make It Fashion: Ukrainian Embroidered PPE in the Time of COVID-19

Embroidered pandemic wear has become one of the newest cultural fashion trends to emerge in Ukraine and within its Canadian diaspora. This article explores the ways in which embroidery as a traditional form of culture retains meaning within modern contexts, while also serving as a vehicle for experimenting with atypical applications of cultural symbols and representations. Throughout the COVID-19 pandemic, cloth masks have been recommended by public health officials, including the World Health Organization, as a preventative measure to limit the spread of the virus. On the basis of digital fieldwork, I discuss the meanings and inspirations behind these embroidered masks, while conducting a material culture analysis of the objects themselves. I argue that, through a subversion of their common purpose— to hide one’s identity— masks have been used in the pandemic as an open/performative display of culture. I contend that this display acts as a means to promote tradition through ephemera and assert cultural importance. This, coupled with the personal/private use of embroidery as a protective talisman, has fueled a trend of embroidered personal protective equipment in popular culture. In this article, I examine the purpose, use, and form of these masks in order to bring light to the ways in which cultural traditions and objects act (and developed prevalence) as a form of pandemic response.

Assessing the impacts of cell wall composition on the optimum stage for “Uradome” in moso bamboo

Snow damage is problematic when cultivating bamboo shoots, and “Uradome”, the practice of removing the tips of new shoots, is used as a preventative measure. Producers perform “Uradome” at empirical times, but there is no scientific basis for this. We hypothesized that differences in the structure and composition of the cell wall might affect the optimal timing of "Uradome" and analyzed the cell wall components of the “Uradome” portion. The lower plant sections broken by the “Uradome” had larger cellulose and lignin depositions than the upper sections. However, there were no differences in the lignin structure or ratio between the upper and lower nodes of the broken sections. This suggests that differences in the degree of cellulose and lignin deposition have significant effects on “Uradome” sites, and that the timing coincides with the development of one or two juvenile branches, which growers empirically consider to be the appropriate time. These results are considered to be new findings that scientifically support the cultivation management of bamboo that has been conducted empirically.

Understanding the nutritional and nutraceutical properties of sorghum

Sorghum is a globally grown cereal. Many sorghum varieties contain high levels of polyphenolic compounds with potential health benefits. With a growing interest in using diet as a preventative measure against chronic diseases, the benefits of sorghum need to be examined. This chapter discusses current research on sorghum and its bioactive compounds, particularly the diversity of polyphenolic compounds present in sorghum. The effects of the phenolic compounds against cancer, their anti-inflammatory properties, anti-obesity effects and effects on gut microbiome are discussed. The chapter also discusses anti-nutritional effects of sorghum polyphenols as well as the effects of processing on bioactive compounds and bioavailability.

Masks and Emasculation: Populist Crisis Rhetoric and the 2020 Presidential Election

This essay illustrates how Donald Trump engaged in what I call “populist crisis rhetoric” throughout the COVID-19 pandemic and coinciding 2020 U.S. presidential campaign cycle. By performing a critical rhetorical analysis of textual fragments surrounding how Trump addressed the preventative measure of mask-wearing, I show how he rejected the role of comforter-in-chief and instead opted for the role of victim-in-chief. Specifically, turning the bare face into a litmus test of Trump loyalism, his rhetoric suggested that masks threatened masculinity and functioned as a form of anti-choice bodily oppression.

On the emergence of antibacterial and antiviral copper cold spray coatings

In this literature review, the antipathogenic properties and contact-mediated antibacterial and antiviral performance of copper cold spray surfaces are assessed and compared with alternative antimicrobial materials that are able to kill and/or inactivate infectious agents via direct contact. Discussion is also provided concerning the suitability of copper cold spray material consolidations as biocidal and viricidal surfaces that retain long-term functionality as a preventative measure against fomite transmission of pathogenic agents and hospital-acquired infections from contaminated high-touch surfaces. Numerable alternative antimicrobial coatings and surfaces that do not rely upon the oligodynamic action of copper are detailed. Given the ongoing need for recognition of said alternative antimicrobial materials by authoritative agencies, such as the U.S. Environmental Protection Agency, the relevant literature on non-copper-based antipathogenic coatings and surfaces are then described. Furthermore, a wide-ranging take on antipathogenic copper cold spray coatings are provided and consideration is given to the distinctive grain-boundary mediated copper ion diffusion pathways found in optimizable, highly deformed, copper cold spray material consolidations that enable pathogen inactivation on surfaces from direct contact. To conclude this literature review, analysis of how copper cold spray coatings can be employed as a preventative measure against COVID-19 was also presented in light of on-going debates surrounding SARS-CoV-2’s non-primary, but non-negligible, secondary transmission pathway, and also presented in conjunction with the inevitability that future pathogens, which will be responsible for forthcoming global pandemics, may spread even more readily via fomite pathways too.

Coronavirus Pandemic: Fear of the Unknown, Shaking Psychological Well-being, Economy, Politics and Morality

The essay examines the meaning and impact of Covid-19 in comparative relation to some of the experiences of the Black Death (1348–1350). It also presents and critically analyses actual case studies of pseudo-named people—in recognition and respect for confidentiality in research ethics—infected by Covid-19. “South Africa” is the primary but not the only focus of this essay. The thesis defended in this essay is that the “social distance” prescribed as a preventative measure to curb the spread of Covid-19 ought to be complemented by ethical “proximity to the other.” Kweli phepha, sizo bonakalisa iintlungu eziviwe ngabantu abaye basuleleka yintsholongwane ye Corona—iSevere Acute Respiratory Syndrome Coronavirus 2 (Covid-19) ngelasemzini. Lentsholongwane ibaphazamise ngokwase moyeni nangokwase ngqondweni. Sizo phinda sijonge ukuba iCorona ingathelekiswa njani nokuba yohluke njani kwi medieval Black Death eyabulala abantu abaninzi mandulo. Abantu aba balisa amabali abo kweli phepha baphiwe amagama angewo wenyani ukuze sibahloniphe, nemfihlo zabo zingafikeleli kubantu ababaziyo.
