The Use of Markov Chains to Estimate Effects of Feedback on Decision-Making

This research paper utilizes Billingsley’s work on Markov processes in the estimation of behavior of the rational decisionmaker.     

Adult learning in the context of African‐American women's voluntary organizations‡

The purpose of this research was to examine non‐formal adult education and informal learning within contemporary African‐American women's voluntary organizations. Face‐to‐face interviews were conducted with 28 women who were members of six different organizations. A semi‐structured interview process was used to elicit their perceptions regarding their (1) involvement in the education of others, (2) learning within the context of performing group membership roles and projects, (3) learning needs, and (4) comparisons of learning in this context with that in more formal educational settings. The findings of the research are discussed in relation to other research on learning in voluntary associations and the workplace. As with other studies of the voluntary association context, respondents did not seem to have given a great deal of prior thought to the nature of their learning within the context, having been more focused on the successful performance of their leadership and service roles than on what is learned from that work. They were none the less able to report numerous examples of how their work helped educate others and how they learned through their experiences. While instances of more systematic non‐formal education (e.g. orientation sessions, lectures and leadership training) were reported, the learning experiences reported more frequently and identified as most valuable seemed to reflect more informal, frequently incidental learning. This significant learning often reflected a perceived change in skills and abilities related to interacting with and working with others toward common goals, or a changing sense of self, in terms of growing self‐confidence and/or sense of connectedness to group members and the community which they sought to serve. Respondents who were quite well educated as a group, nevertheless generally indicated their preferences for the kind of interactive, experiential and situated learning that occurred as an outgrowth of group participation over the more abstract, teacher‐controlled learning they associated with formal education. These findings are discussed in terms of their importance to our understanding of informal learning, particularly that which occurs within the voluntary sector. Exploring this learning in a context specific to African‐American women is also seen as a way of moving beyond the culturally biased sampling often criticized in adult learning research.

     

How Can Genetically Informed Research Help Inform the Next Generation of Interparental and Parenting Interventions?

There is robust evidence that the interparental relationship and parenting behaviors each have a significant influence on children's risk for emotional (internalizing) and behavioral (externalizing) problems. Indeed, interventions targeting the interparental relationship and parenting processes show significant intervention‐related reductions in child internalizing and externalizing problems. However, most evidence‐based parenting‐ and couple‐focused interventions result in small to medium effects on children's emotional and behavior problems. It is proposed that there is opportunity to improve upon these interventions through incorporation of knowledge from quantitative genetic research. Three core recommendations are provided for practitioners engaging in intervention work with children and families. These recommendations are contextualized relative to what quantitative genetic studies can tell us about the role of the interparental relationship and parenting behaviors on child outcomes.     

Trajectories of parenting and child negative emotionality during infancy and toddlerhood: a longitudinal analysis

The current longitudinal study examined trajectories of child negative emotionality, parenting efficacy, and overreactive parenting among 382 adoptive families during infancy and toddlerhood. Data were collected from adoptive parents when the children were 9-, 18-, and 27-month-old. Latent growth curve modeling indicated age-related increases in child negative emotionality and overreactive parenting for adoptive fathers and adoptive mothers (AM), and decreases in parent efficacy among AM. Increases in child negative emotionality were also associated with increases in parent overreactivity and decreases in maternal efficacy. Mothers' and fathers' developmental patterns were linked within but not across parenting domains. Limitations and directions for future research are discussed.     

Component structure,reliability, and stability of Lawrence’s Self‐Esteem Questionnaire (LAWSEQ)

Lawrence’s Self‐Esteem Questionnaire (LAWSEQ) was administered to 120 Year 1 pupils in six schools in Belfast, Northern Ireland. A principal components analysis indicated that the scale items were unidimensional and that the reliability of the scores, as estimated by Cronbach’s alpha, was satisfactory (α = .73). There were no differences between boys and girls on either total scores or the individual items comprising the LAWSEQ. A follow‐up study, involving 71 of the children in Year 3, confirmed these findings but the stability of the scores between the two occasions (as indicated by Pearson’s r) was extremely low.     

Visual spatial representation in mathematical problem solving by deaf and hearing students

This research examined the use of visual-spatial representation by deaf and hearing students while solving mathematical problems. The connection between spatial skills and success in mathematics performance has long been established in the literature. This study examined the distinction between visual-spatial "schematic" representations that encode the spatial relations described in a problem versus visual-spatial "pictorial" representations that encode only the visual appearance of the objects described in a problem. A total of 305 hearing (n = 156) and deaf (n = 149) participants from middle school, high school, and college participated in this study. At all educational levels, the hearing students performed significantly better in solving the mathematical problems compared to their deaf peers. Although the deaf baccalaureate students exhibited the highest performance of all the deaf participants, they only performed as well as the hearing middle school students who were the lowest scoring hearing group. Deaf students remained flat in their performance on the mathematical problem-solving task from middle school through the college associate degree level. The analysis of the students' problem representations showed that the hearing participants utilized visual-spatial schematic representation to a greater extent than did the deaf participants. However, the use of visual-spatial schematic representations was a stronger positive predictor of mathematical problem-solving performance for the deaf students. When deaf students' problem representation focused simply on the visual-spatial pictorial or iconic aspects of the mathematical problems, there was a negative predictive relationship with their problem-solving performance. On two measures of visual-spatial abilities, the hearing students in high school and college performed significantly better than their deaf peers.
