Monitoring Scale Scores over Time via Quality Control Charts, Model-Based Approaches, and Time Series Techniques

Maintaining a stable score scale over time is critical for all standardized educational assessments. Traditional quality control tools and approaches for assessing scale drift either require special equating designs, or may be too time-consuming to be considered on a regular basis with an operational test that has a short time window between an administration and its score reporting. Thus, the traditional methods are not sufficient to catch unusual testing outcomes in a timely manner. This paper presents a new approach for score monitoring and assessment of scale drift. It involves quality control charts, model-based approaches, and time series techniques to accommodate the following needs of monitoring scale scores: continuous monitoring, adjustment of customary variations, identification of abrupt shifts, and assessment of autocorrelation. Performance of the methodologies is evaluated using manipulated data based on real responses from 71 administrations of a large-scale high-stakes language assessment.     

Behavioral interference and C/EBPbeta expression in the insular-cortex reveal a prolonged time period for taste memory consolidation

Memory consolidation is defined as the time window during which the memory trace is susceptible to behavioral, electrical, or pharmacological interventions. Here, we presented rats with two novel tastes at consecutive time intervals. Clear interference was evident when a novel taste formed the second taste input whereby, surprisingly, the time window for interference was found to last more than 10 h. In addition, we detected an increase of C/EBPbeta protein expression in the gustatory cortex 18 h after novel taste learning. This modulation was attenuated by a subsequent novel taste. Our findings reveal temporal constraints and a lingering nature of taste memory consolidation.     

Reproduction of seen actions: stimulus-selective learning

Subjects observed and reproduced abstract, irregular stimulus models generated by the steady movement of a disk across two-dimensional paths. The paths comprised 3 to 7 randomly oriented linear segments linked head-to-foot. Reproductions were expressed by moving a stylus over the surface of a graphics tablet while the disk was tracing its trajectory (concurrent reproduction), or soon after the disk had finished (delayed reproduction). For both concurrent and delayed conditions, fidelity of reproduction fell with increasing number of segments in the model. Overall quality of reproduction did not differ between the two conditions. When a few models were repeated, interspersed among non-repeated ones, performance improved but only when reproduction was delayed. This improvement was stimulus-selective, not a general improvement with practice. Two additional experiments showed that (i) memory for a seen model is well preserved for at least 6 s, with relatively modest need for rehearsal, and (ii) successful reproduction is possible with remarkably little information having been extracted from key points in the model's trajectory.     

The Influences of Friends' and Parental Smoking on Adolescent Smoking Behavior: The Effects of Time and Prior Smoking1

This research examines the relative importance of parental and friends' influences on adolescents' smoking behavior and changes in the effects of social influences during adolescence. Data were collected at 4 times from 7th to 9th grades. Random-effects ordinal regression models were employed to predict the repeated classification of adolescent smoking status using time effects, prior smoking status, friends' smoking, and parental smoking. In general, the effects of friends' smoking are stronger than those of parental smoking, and these differences increase over time. In addition, friends' smoking has greater effects on nonsmokers than smokers. Separate models for males and females disclose some gender differences. In particular, the effects of friends' smoking are stronger for females than for males, and the increasing trend of friends' influences is more noticeable for females than for males. Models for 4 ethnic groups also suggest differential susceptibility to social influences in different cultures.

The Role of Families in Adolescent HIV Prevention: A Review

Recent research has highlighted the significant contribution families make in the prevention of HIV risk behaviors among adolescents. As the most proximal and fundamental social system influencing child development, families provide many of the factors that protect adolescents from engaging in sexual risk behaviors. Among these are positive family relations, effective communication about sexuality and safer sexual behaviors, enhancement and support of academic functioning, and monitoring of peer activities. HIV risk behaviors occur in a social context, and it is becoming clear that the earliest and most effective way to intervene is in the context where one initially learns about relationships and behavior—the family. Both the Centers for Disease Control and Prevention and the National Institute for Mental Health have taken steps to support and emphasize research that will further elucidate our understanding of the role of families in HIV prevention. This article uses Ecodevelopmental Theory to guide and organize the findings of this promising research area. Within this context, and with special attention to the comorbidity of adolescent problem behaviors, this article reviews empirical research on the role of families in HIV prevention, discusses current intervention efforts that involve families and ecosystems, and addresses prospects and implications for future research and interventions.     

Early Feeding,Child Behaviour and Parenting as Correlates of Problem Eating

Mealtimes are a common source of stress for families. Examining factors related to problem eating may provide markers by which to identify families requiring assistance and salient targets for treatment. The current study investigated parenting practices and cognitions, generalisation of child behavioural issues, and early feeding history as they relate to problem eating in typically developing young children. We compared a community sample of 105 parents of 1.5–6-year-old children via survey and observation with 96 parents seeking treatment for their child’s problem eating. History of problems with breastfeeding, χ²(1)?=?3.88, p?=?.049, and the transition to solids, χ²(1)?=?7.27, p?=?.007, were more common among problem eaters than comparisons. Problem eaters had a greater number of problem behaviours outside of mealtimes, F(1181)?=?10.88, p?=?.001, though not more frequently than comparisons and not to clinical levels, F(1181)?=?1.81, p?=?.181. Parents of problem eaters reported more unhelpful mealtime parenting strategies, F(1155)?=?22.59, p?<?.001, yet general parenting style was similar by group, F(1187)?=?0.42, p?=?.527. Parents’ cognitions about mealtimes, F(1155)?=?119.81, p?<?.001, including mealtime-specific self-efficacy, F(1155)?=?171.30, p?<?.001, were poorer amongst problem eaters, and were the only factors to predict problem eating in the total sample. General parenting self-efficacy was poorer in parents of problem eaters (Behaviour: F(1187)?=?42.36, p?<?.001; Setting: F(1187)?=?10.64, p?=?.001). Evidence of feeding issues in infancy may support early detection of and intervention for later problem eating. The significance of broader child behaviour is less clear. Parent factors, particularly those specific to mealtimes, and cognitive in nature (including mealtime parenting self-efficacy) clearly differentiated the groups, and represent important targets for intervention.     

Diversity and Dance: Exploring the Therapeutic Implications of World Dance

This phenomenological study examined the potential power of world dance as a therapeutic tool. The lived experiences of adult females (N = 16) were explored to understand the purposive essence of dance and subsequent benefits to mental health. Findings revealed 15 themes in total: 11 themes highlighted potential benefits of world dance, such as social support and stress relief, and four themes noted potential obstacles to using world dance as a therapeutic tool, such as access or finances. Implications for using world dance within creative counseling practice are provided.     

Adolescents’ Psychological Well-Being and Memory for Life Events: Influences on Life Satisfaction with Respect to Temperamental Dispositions

The aim of the present study was to explore how the number of recalled life events (positive and negative) predicts psychological well-being (PWB) and how PWB predicts life satisfaction (LS). In addition, participants were categorized into one of four different affective temperaments (self-actualizing, high affective, low affective, and self-destructive). One hundred and thirty-five high school students participated in completing the SWLS (LS), PWB (short-version), PANAS (to create affective temperaments), and the life events recollection task. Results indicated that adolescents with high positive affect also had high PWB; adolescents with low affective profiles also had high PWB. Positive and negative life events predicted PWB for self-destructive temperaments, whereas positive life events predicted PWB for low affective temperaments. PWB predicted LS for all temperaments except the self-actualizing group. In conclusion, the temperament combinations may allow the individual to achieve PWB and LS. Even more importantly, selfacceptance may foster LS regardless of temperament and may have more impact on LS than life events.
