Handling Missing Data in the Modeling of Intensive Longitudinal Data

Myriad approaches for handling missing data exist in the literature. However, few studies have investigated the tenability and utility of these approaches when used with intensive longitudinal data. In this study, we compare and illustrate two multiple imputation (MI) approaches for coping with missingness in fitting multivariate time-series models under different missing data mechanisms. They include a full MI approach, in which all dependent variables and covariates are imputed simultaneously, and a partial MI approach, in which missing covariates are imputed with MI, whereas missingness in the dependent variables is handled via full information maximum likelihood estimation. We found that under correctly specified models, partial MI produces the best overall estimation results. We discuss the strengths and limitations of the two MI approaches, and demonstrate their use with an empirical data set in which children’s influences on parental conflicts are modeled as covariates over the course of 15 days (Schermerhorn, Chow, & Cummings, 2010).     

What has <Emphasis Type="Italic">Harry Potter</Emphasis> Done for Me? Children’s Reflections on their ‘<Emphasis Type="Italic">Potter</Emphasis> Experience’

This article reports findings from a small-scale focus-group study funded by the British Academy. Drawing on Herbert Marsh and Richard Shavelson’s notion of “Academic Self-Concept” and David Barton and Mary Hamilton’s view of literacy as context-specific social practices, the authors examine what young British Harry Potter enthusiasts perceive as the influence of the novels on their subsequent reading behaviour and academic development. Specifically, they consider whether these children feel that Harry Potter has helped improve their literacy skills and whether they think the books have changed their attitudes to reading. Moreover, the article sheds light on the role of the films and the possible effect of gender. The authors conclude that the Potter enthusiasts they have interviewed see the series as formative in terms of their literacy. However, regarding gender, intra-group variation (differences among individual readers in a group of either boys or girls) is far more significant than inter-group variation (differences between single-sex groups of boys and girls).

Gender Roles at Home and School

Parents of 116 first‐year pupils at an urban comprehensive school were studied by questionnaire and interview. They were asked about their educational and occupational aspirations for their children, their views on sexual equality and their children's out‐of‐school activities. Educational aspirations were found to be high, with little differentiation between the sexes. Parents were enthusiastic about their daughters studying physical science and neutral about craft subjects. Occupational aspirations were also high and although they tended to be sex‐stereotyped, parents were found to be generally supportive of non‐traditional choices. Class differences were few. Most parents were in favour of working mothers, equal pay and men helping with housework. However these egalitarian attitudes coexisted with more traditional assumptions about male breadwinners and a woman's main responsibility being to her children. Parents’ own domestic labour and that which they required of their children was strongly sex‐stereotyped. The messages which children receive about gender from their homes are contradictory, but not as uniformly traditional as many teachers assume.     

Memorable Messages as Sources of Hope

Based on hope theory, this study examined potential links between hope and memorable messages. Using qualitative methods, the authors coded the content and form of memorable messages in three domains: academics, relationships, and finances. Quantitative analysis then tested if the memorable message characteristics of positivity and efficacy were associated with dispositional and domain-specific hope. Consistent with predictions, participants with higher dispositional hope reported more positive and efficacious messages across message domains. Hierarchical regression analysis suggested that the agency, but not the pathways, dimension of dispositional hope predicted message positivity and efficacy. Regression results also indicated that participants with higher domain-specific pathways reported more efficacious memorable messages.     

Bringing Dinosaur Science to the Junior Girl Scouts Through a College Service-Learning Project

Undergraduate students in an introductory-level geoscience course successfully designed and conducted a science badge day for the Junior Girl Scouts. With national concerns that girls turn away from science at a young age, a service-learning project was incorporated into a college course with the end result providing a group of girls a positive and fun science-learning experience. A number of science and technology badges exist for the Girl Scouts, yet not many of these badges have been completed because of a lack of confidence the troop leaders have in teaching science and a paucity of scheduled science events for the leaders to take their girls. Junior Girl Scout troops were invited to the Pennsylvania State University Delaware County campus to complete a series of hands-on dinosaur science activities that allowed them to earn the Science in Everyday Life badge. At the conclusion of the badge event, the girls reported a greater interest in science, a desire to learn more science, and a desire to complete additional science-related Girl Scout badges.
