Immigration disrupts the bonding process in families. Maintaining close relationships with adult children can be an important protective factor for older immigrants' health and wellbeing. Quantitative research explaining such close relationships is rare. This study examined factors associated with close parent–child relationships in a purposive sample of 236 older Chinese immigrants in Los Angeles who provided information regarding 365 children. Two-level regression models were estimated to investigate factors contributing to cohesive parent–child relationships among these older adults. The findings showed that co-residence, a characteristic that distinguishes immigrant families from most non-immigrant families, was associated with lower parent–child relationship quality. Frequent contact was associated with closer relationships. While receiving instrumental and monetary support from children was associated with favourable ratings of relationships with children, providing such support to children was not related to parents' assessment of relationship quality. Parental perceptions of children being respectful was also associated with better relationship quality ratings. Overall, the findings demonstrate how family-related changes in the immigration context shape parent–child relationships in later life. Implications for future research and practice are provided.

An experimental study for determining the thermal contact conductance between two periodically contacting surfaces is presented. The influence of the frequency of contact upon the thermal contact conductance is investigated. Also, the results show that the thermal contactconductance decreases as the frequency of contact increases. The experimental results obtained from present work are in agreement with the previous published data.
