Deletion mapping has been used to order 12 Λ rex- mutants. Correlation of recombination data with physically-determined positions of deletion end-points (SZYBALSKI 1971; BLATTNER et al. 1972) suggests that the left-most rex- mutation, rex209, is located about 260-300 nucleotide pairs from the PL mutation sex1 and abut 475 nucleotide pairs from the left end-paint of the region of nonhomology with Λimm434.
In order to test three hypotheses relating fears of flying and death, 249 persons comprising three groups were questioned. Pre- and post-flight samples were obtained at an airport and members of a street (control) group were interviewed in non-airport settings. Two of the hypotheses obtained support. Fears of flying and death tend to be positively associated and insurance buying may mitigate such anxiety. The roles of sex, age and religiosity were also assessed. Suggestions that the pre-flight group was experiencing stress and resolving anxiety via denial were inferred from the pattern of death-flying item relationships observed.
With an increasing number of addicted people seeking help towards their recoveries, clinical nurses working in the addictions-recovery field are in an excellent position to expand their roles to treat this needy population. The "authenticity model" offers a new way for nurses to increase their skills, knowledge, life experience, and current nursing and addictions theories. The author presents the rationale for an authenticity model and its structure, basic assumptions and tasks, as well as anecdotal examples and a discussion of nurses' use of the authenticity model.
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.
