Adolescents’ Empathy and Prosocial Behavior in the Family Context: A Longitudinal Study

Children’s empathy and prosocial behavior play an important role in their social competence. Of the influential factors, research has demonstrated that parental behaviors and the quality of the parent–child relationship are important correlates of children’s development of empathy and prosocial behavior. The current study examined the associations between different types of parental behaviors (i.e., parental knowledge, parental solicitation, and parental psychological control), “balanced connectedness” in the parent–child relationship, which allows for both closeness and autonomy, and empathy and prosocial behavior in adolescents. The participants were 335 married couples (more than 80 % European American) and their adolescent child (49.0 % female; 10–13 years). Data were collected at three time points for parental behaviors, balanced parent–child connectedness, and adolescents’ empathy and prosocial behavior, respectively. The results of structural equation modeling suggested that adolescents’ perceptions of parental solicitation and parental psychological control may be associated with their empathy and prosocial behavior through their perceived balanced connectedness with parents. These findings suggest that enhancing balanced connectedness in the parent–child relationship may contribute to promoting empathy and prosocial behavior in adolescents over time. Further, this study suggests that parental solicitation may play a role in adolescents’ empathic and prosocial development, possibly depending on the quality of the parent–child relationship.     

Alterations of Length Heteroplasmy in Mitochondrial DNA Under Various Amplification Conditions*

Abstract: There are several areas within mitochondrial DNA that show length heteroplasmy. If the heteroplasmy pattern is unique and consistent for each person, it may be used to support an interpretation of exclusion in identity testing. We investigated whether the length heteroplasmy pattern would be consistent under different amplification conditions. We also determined whether various amplification parameters would affect the homopolymeric cytosine stretches (C‐stretch) in HV1. Monoclonal samples tended to be heteroplasmic after amplification. After several repetitions, C‐stretch patterns of all samples were inconsistent even under the same amplification conditions. Increased PCR cycles and high template concentrations resulted in a more frequent heteroplasmic tendency. These amplification parameters seem to have little effect if samples are not long enough in C‐stretch or total length of the segment from nt 16180 to nt 16193. It is suggested that the pattern of length heteroplasmy cannot be used as an additional polymorphic marker.     

Capital Account Liberalization,Financial Structure,and Access to Credit in Latin America

This article revisits the question of whether capital account liberalization improves access to credit by advancing and testing a theory of how the structure of the financial sector shapes the willingness and ability of banks and governments to repress the domestic financial sector. In a highly concentrated financial sector, banks and governments are more willing to reap the benefits of financial openness by suppressing liberalizing reforms to domestic financial policies, and they can also better coordinate with one another to stifle these reforms compared to when the financial sector is diffuse. Using a panel dataset of Latin American and Caribbean countries, I find that capital account liberalization leads to a decrease in loans to private firms and households and an increase in loans to governments and state-owned enterprises when the financial sector is highly concentrated. Only when the financial sector is diffuse does capital account liberalization lead to reforms in entry barriers, directed credit programs, and banking sector supervision, which extends to improved access to credit for private firms and households.
