Grounded by the ecological systems perspectives proposed by Bronfenbrenner (1977, 1979) and Fivush and Merrill (2016), the present study was conducted to examine whether autobiographical memory (AM) and self-construal differed in young adults raised in the same macrosystem, but with unique microsystems. European American (EA) participants were born in the United States to mothers who were born in the United States (n = 61) and Chinese American (CA) participants were born in the United States to mothers who were born in China (n = 47). Participants completed an online study in which they reported on and rated aspects of their earliest memory; they also completed measures of self-construal and acculturation. EA participants identified more with mainstream American culture relative to CA participants, who identified to a greater extent with their heritage culture. EA participants also talked and thought more about their earliest memories relative to CA participants; interactions between group and sex were found for social words. Group differences were not observed on measures of self-construal. These findings indicate that microsystem-level factors are associated with differences in AM in young adults even when individuals are born and raised in the same macro-level cultural environment.

This study was designed to conduct systematic reviews of existing evaporative cooling system maintenance guidelines and of published Legionnaires' disease outbreaks to determine what, if any, maintenance practices were in place at the time of the disease outbreaks and then to contrast the reported practices with the published guidelines for evaporative cooling systems. For the first review, similarities in the reported recommendations were assessed; in the second review, any reported information about the state of the evaporative cooling system during the outbreak investigation was summarized. The systematic reviews yielded 38 current guidelines for evaporative cooling systems and 38 published outbreak investigations. The guidelines varied regarding the recommended type and dose of biocides, frequency of general inspections and total system maintenance, the preferred disinfection and cleaning procedures when testing a system for microbiological contamination, the type and frequency of testing procedures, and interpretation of test results. Overall, the maintenance guidelines did not contain sufficiently detailed procedures to prevent the problems that were observed in the outbreak investigations. These maintenance procedures included lack or improper use of a biocide; infrequent testing for microbiological contamination; improper use or maintenance of drift eliminators; and lack of a total system cleaning within 6 months of the outbreak for cooling systems that were either under continuous use, recently started up, or frequently switched on and off. This study suggests that more specific and standardized maintenance guidelines for the control of Legionella bacteria are needed and that these guidelines must be properly implemented to help reduce further Legionnaires' disease outbreaks associated with evaporative cooling systems.
