Rethinking the frontiers of vaccine acceptance: Impact of visual messages in promoting the actual intake of COVID-19 vaccines among vulnerable populations.

Studies on COVID-19 vaccine mainly focused on behavior intention and rarely on actual intake. This study attempted to fill this gap by assessing the impact of visual artistic messages on COVID-19 vaccination among victims of insecurity. The study was a quasi-experiment involving 362 victims of insecurity. There were two groups in the quasi experiment known as control and treatment groups. The former did not receive the intervention while the latter did. The results of the study revealed that vaccination among the participants in the visual intervention improved from 12% before the visual intervention to 74% after the intervention and 95% after 6 months of follow-up assessment. On the contrary, COVID-19 vaccination for the no visual intervention only slightly improved from 13% to 18% and 19%, respectively, within the same time framework. The study expands the argument on security discourse by highlighting the need to consider the health welfare of victims of armed conflict as part of the larger security discourse. Doing so will not only improves existing literature but also provides the needed empirical data that will guide policies and program on security issues. Theoretically, the study has offered fresh understanding regarding variables from the health belief model, such as perceived severity and perceived vulnerability.

Non-Aufbau orbital ordering and spin density modulation in high-spin donor-acceptor conjugated polymers.

High-spin ground-state organic materials with unique spin topology can significantly impact molecular magnetism, spintronics, and quantum computing devices. However, strategies to control the spin topology and alignment of the unpaired spins in different molecular orbitals are not well understood. Here, we report modulating spin distribution along the molecular backbone in high-spin ground-state donor-acceptor (D-A) conjugated polymers. Density functional theory calculations indicate that substitution of different heteroatoms (such as C, Si, N, and Se) alters the aromatic character in the thiadiazole unit of the benzobisthiadiazole (BBT) acceptor and modulates the oligomer length to result in high-spin triplet ground-state, orbital and spin topology. The C, Si, and Se atom substituted polymers show a localized spin density at the two opposite ends of the polymers. However, a delocalized spin distribution is observed in the N substituted polymer. We find that the hybridization (sp3vs. sp2) of the substituent atom plays an important role in controlling the electronic structure of these materials. This study shows that atomistic engineering is an efficient technique to tune the spin topologies and electronic configurations in the high-spin ground-state donor-acceptor conjugated polymers, compelling synthetic targets for room-temperature magnetic materials.
