BACKGROUND: Previous studies have demonstrated low first-time donor return rates (DRR) following catastrophic events. Little is known, however, about the influence of demographic factors on the DRR of first-time donors during the COVID-19 pandemic, including the unique motivation of COVID-19 convalescent plasma (CCP) donors as compared to non-CCP donors.

In a recent paper (Dennison, 2019) the term “human default consciousness” (DCs) was coined to describe the everyday consciousness that we live within throughout most of our lives. The default nature of that consciousness was highlighted by its profound disruption during a littleknown yet core practice within Buddhist meditation traditions, jhāna meditation, which explicitly requires meditators to withdraw or disengage, temporarily, from engagement with the sensory world. The default consciousness is therefore a sensorily-based consciousness. The profound effects on brain activity that were observed to result from this withdrawal highlighted just how powerfully embedded the default consciousness is, and what a significant undertaking it is to disengage the personal element. In this chapter we explore in more detail the characteristics of the DCs as it has featured in philosophic thought, in psychoanalysis and mental health, as well as in Buddhist thought and from a modern neuroscience perspective. We then compare and contrast the form of consciousness that emerges in jhana meditation, before extending the discussion to recent neuroscience models of nested hierarchies within self-organising systems and their associated Markov blankets, with implications for the forms of consciousness that may or may not arise in those systems. We also discuss briefly the outermost hierarchical system, that of planet Earth in interaction with worldwide societies, and the likely information geometries linking “outer” with “inner.” In light of the current crises of climate change and the Covid-19 pandemic, we speculate on the possibility of breakdown of this outermost Markov blanket system. © 2021 Nova Science Publishers, Inc.

OBJECTIVES: Estimate the point prevalence of COVID-19 vaccine acceptability among US firefighters and Emergency Medical Services (EMS) workers. METHODS: A cross-sectional study design was used to administer an anonymous online survey to a national non-probabilistic sample of firefighter and EMS workers. RESULTS: Among the 3169 respondents, 48.2% expressed high acceptability of the COVID-19 vaccine when it becomes available, while 24.2% were unsure and 27.6% reported low acceptability. Using the "high COVID-19 vaccine acceptability" group as the reference category, the groups with greater odds of reporting low acceptability included those: 30 to 39 years of age (odds ratio = 3.62 [95% confidence interval = 2.00 to 6.55]), Black race (3.60 [1.12 to 11.53]), Hispanic/Latinx ethnicity (2.39 [1.45 to 3.92]), with some college education (2.06 [1.29 to 3.27]), married (1.65 [1.03 to 2.65]), of current rank firefighter/EMS (2.21 [1.60 to 3.08]). CONCLUSIONS: Over half of US firefighters and EMS workers were uncertain or reported low acceptability of the COVID-19 vaccine when it becomes available.
