Soon after the coronavirus disease 2019 (COVID‐19) pandemic outbreak, it became clear that vaccination will be the most useful tool to combat the disease. Despite the apparent safety and efficacy of the developed anti‐COVID‐19 vaccines, relatively high percentages of the population worldwide refused to get vaccinated, including many health workers and health students. The present cross‐sectional study examined the motives, attitudes, and personal characteristics of those who did not get vaccinated against COVID‐19 or vaccinated without complete willingness among nursing students (...) and nursing faculty members in Israel (n = 472). Results show that the vast majority of the study participants (97%) received at least one dose of the anti‐COVID‐19 vaccine. Nearly 37% of the participants indicated that they received the vaccine without complete willingness. As compared to faculty members, nursing students reported lower trust in the efficacy of the vaccine, perceived the COVID‐19 pandemic as a health threat to a lesser extent, exhibited lower institutional and personal trust, and had higher levels of posttraumatic stress disorder symptoms. Non‐Jewish participants were at risk of vaccinating without complete willingness. These findings underscore the need for developing evidence‐based strategies to promote the safety and efficacy of the anti‐COVID‐19 vaccines in nursing schools. (shrink)

Biton’s Construction of Machines of War and Catapults describes six machines by five engineers or inventors; the fourth machine is a rolling elevatable scaling ladder, named sambukē, designed by one Damis of Kolophōn. The first sambukē was invented by Herakleides of Taras, in 214 BCE, for the Roman siege of Syracuse. Biton is often dismissed as incomprehensible or preposterous. I here argue that the account of Damis’ device is largely coherent and shows that Biton understood that Damis (...) had built a machine that embodied Archimedean principles. The machine embodies three such principles: (1) the proportionate balancing of the torques on a lever (from Plane Equilibria, an early work); (2) the concept of specific gravity or density (from Floating Bodies, a late work); and (3) the κοχλίας, i.e., a worm drive (invented ca 240 BCE), with the toothed wheel functioning as the horizontal axis of rotation of the elevated ladder. Moreover, the stone-thrower of Isidoros of Abydos (the second machine in Biton) also embodies the κοχλίας. (shrink)

I argue that Herodotus consciously and cunningly incorporates elements of myth and initiatory ritual into his story of Cleobis and Biton. The brothers' "blessed" death takes place in the context of an Argive initiatory festival, at the unintentional bidding of their mother, who thus embodies the link between maternity and mortality attested in early Greek hexameter poetry. The posthumous dedication by their fellow citizens of statues of the brothers at Delphi signifies both an honorary initiation into the class of (...) adult male warriors and a mitigation of mortality (another fundamental concern of early Greek myth).
