Purpose -In the disaster mitigation community, one of the most important tasks is that of information transfer prior to, and following natural disasters. The purpose of this research project was to increase the understanding of key aspects (such as attractiveness and educational value) that influence the utility and effectiveness of educational media tools for home resilience during hurricanes. Design/methodology/approach -A total of three types of educational media were developed -pulp board coasters, tri-fold pamphlets, and a web hosted video. The contents of these media were developed based on data from federal agencies, as well as scholarly articles and technical reports to form an inclusive body of information. Several focus groups of homeowners and potential homeowners were held to evaluate participant's preference of these three media tools with regards to their usefulness for making homes safer during natural disasters, specifically during wind and wind-driven rain events (e.g. hurricanes). Findings -Analysis of the focus groups indicate that media use (based on disaster prevention home resilience practices) is highly dependent on the target audience or the stakeholder group (e.g. consumers look for different information content as compared to the builders). While all three media were indicated by the participants to have merit, the pamphlet was preferred aesthetically and was most likely to be used by homeowners. In addition, the study found that the usefulness of the tools depends on the ease of understanding and implementation of the best practices and ease of access to the tools (targeted location for each media).Research limitations/implications -The findings of the study have implications for the entire disaster educational community. Although the findings are mostly qualitative and the small sample used in the focus groups limits the generalize ability to the entire population of the USA, nevertheless, future educational information and tools used should follow easy to understand language, be illustrated with examples and pictures, and be placed at convenient locations for homeowners to access. Originality/value -By understanding how to better reach homeowners with information on home resilience, information can be more effectively disseminated to the public which allows for efficient use of tools as well as funds.
Vessel and fiber properties, diameter growth, and chemical compositions were investigated for transgenic Populus trichocarpa (black cottonwood) trees harvested after six months of growth in a greenhouse. Genetic modifications were cinnamyl alcohol dehydrogenase (CAD), cinnamate 3-hydroxylase (C3H), or cinnamate 4-hydroxylase (C4H), which resulted in modified lignin composition or content, and changed the syringyl-to-guaiacyl ratio. Comparing the genetic groups to the wild-type as the control, trees with reduced lignin content showed different results for vessel and fiber properties measured. Genetic groups with reduced PtrC3H3 and PtrC4H1&2 (with lower lignin content and higher S/G ratio than the control) exhibited splitting perpendicular to the rays, yet had the same fiber lumen diameter and the same fiber cell wall thickness as the control. Changes in lignin structure from modifications to PtrCAD resulted in reductions to the number of vessels, increases in vessel and fiber diameters, and had no consistent impact on stem diameter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
