30. Animal-assisted activity: experiences of institutionalized Japanese older adults.

Author

Kawamura N, Niiyama M, and Niiyama H

Abstract

The purpose of this study was to determine how a group of institutionalized elderly Japanese women perceived animal-assisted activity (AAA) and how their perceptions may be relevant to clinical nursing practices in the AAA context. The participants in this study, 8 elderly Japanese women residing in a nursing home in a northern Japanese city, had attended AAA sessions two times per month for 2 years prior to this study's data collection. Semi-structured interviews were conducted, and data were analyzed using phenomenological procedures. Six themes emerged concerning the interactive relationships between the participants andthe animals; in addition, participants were able to develop interest in themselves, other residents, and their environment, due to feelings of ease and the development of one-on-one relationships with the AAA dogs. Volunteers from outside the nursing home made residents feel refreshed and gave them opportunities to broaden their contact with society. [ABSTRACT FROM AUTHOR]

31. Males with short horns spent more time mating in the Japanese horned beetle Allomyrina dichotoma.

Abstract

We examined the relationships between male body and horn sizes and mating duration in the Japanese horned beetle, Allomyrina dichotoma. Smaller males possessing shorter horns spent more time for copulation with a female and mounting the female without copulation. The results of multiple regression analyses indicate that the horn length is a determining factor for the time spent by the males during mating. A previous study has documented that the horn length of male A. dichotoma primarily determined the outcomes of aggressive male–male interactions; hence, predicts access to females. Therefore, instead of fighting for females, males possessing short horns may maximize their fertilization success by mating longer with the few females they have access to. [ABSTRACT FROM AUTHOR]
