The current study investigated the relationships between current attachment to mother and attachment to romantic partners, and the role of current partner support and culture as moderators of that relationship. University students who were currently in a romantic relationship were recruited from Hong Kong and USA, and completed measures on attachment styles and partner support. Results showed that maternal attachment anxiety was correlated with romantic attachment anxiety; maternal attachment avoidance was correlated with romantic attachment avoidance, but this linkage varied by level of current partner support. Romantic attachment avoidance was also associated with current partner support, but this linkage was stronger for HK Chinese than for Americans. These results are discussed in terms of how interpersonal and personality factors promoted by culture can affect the developmental course of romantic relationships.

This paper was intended to explore the mutual influences between electric vehicle (EV) charging and charging facility planning, to establish a two-stage model for optimizing the EVs' charging and charging piles' selection. In the first stage, the distribution pattern of the demands for EV charging, and various EVs were effectively grouped, in order to reduce the amount of computation for solving the second stage model. The goal of the second stage was to minimize the annual investment and electricity purchasing costs on the charging piles, and the coordinated optimization was carried out for EV charging and charging pile selection. The CPLEX and IP_SOLVE packages were used in MATLAB (R2014a/64 bits) to solve the established optimization model. The simulation results showed that, compared with the scheme for selecting the charging pile under the typical charging pattern (TCP), the total cost of the charging pile could be reduced by 6.32% with a scheme under the optimized charging pattern (OCP), thereby promoting the coordinated development of both the EVs and charging facilities.
