Adolescents' Emotional Experiences of Mother–Adolescent Conflict Predict Internalizing and Externalizing Symptoms

Research on adolescent emotion has generally focused on expressions of emotion; however, there are reasons to believe that adolescents' experiences of emotion may be related to adolescent development in unique and important ways. This study examined the relation of adolescents' emotional experiences of conflict with their mothers to their internalizing and externalizing symptoms at three time points, each a year apart. After participating in videotaped conflict negotiation tasks with their mothers, adolescents (N=80) watched the videotape of their interactions and used a joystick to make continuous ratings of how negative, positive, or neutral they felt during the discussions. Hierarchical Linear Modeling was used to assess relations among their continuous emotion ratings and their internalizing and externalizing symptoms 1 year before the interaction task, at the time of the interaction task, and 1 year later. Adolescents' externalizing symptoms at the time of the conflict task were associated with negative emotion that decreased across the conflict discussion. Relations between emotional experience and internalizing symptoms a year later were moderated by adolescent gender, revealing that a tolerance for increasing negative emotion predicts fewer future internalizing symptoms for girls. The importance of adolescents' ability to tolerate negative emotion during normal developmental conflicts is discussed.     

The Significance of Shift Work: Current Status and Future Directions

This paper provides a review and synthesis of research literature on the effects of shift work on workers’ physical health, mental health/well-being, and family life. The focus is on current knowledge, unanswered questions, and new directions for future research. The selection of research literature is guided by a general conceptual framework that identifies predictor variables, moderating variables, and outcome variables. The paper concludes with a discussion of the variables that should be incorporated into an agenda for future research.     

On the dynamics of populations with two age groups

By restricting the number of age groups to two and by introducing continued fractions, the dynamics of populations with deterministically changing vital rates are completely specified at all times. Explicit expressions for the sequence of the product of population projection matrices are given. From these, relative age distribution and reproductive values to any desired accuracy are obtained as functions of the vital rates. Thus, the results given in this paper are stronger than any existing weak ergodic theorems.     

Critical understandings of child development: the development of a module for a post-qualifying certificate course in child protection studies

This paper explores the dilemmas involved in selecting appropriate theoretical and research material to help social workers in practice. Concentrating on the needs of those working in child care and protection, the paper uses the example of the area of child development knowledge to illustrate a process of presenting theory for practice. Specifically, the focus is on the redevelopment of a child development module for a post-qualifying certificate course in child care and protection that aims to encourage students to make critical use of current research and theory. The paper explains the reasoning behind the choice of attachment theory as the underpinning theoretical framework. It also addresses possible pitfalls in an uncritical use of such theory. The paper finally sets out how the module addresses the need social workers have for a framework to guide intervention in individual cases. The dimensions described are those of individual vulnerability or resilience and factors in the environment that are adverse or protective.
