Fetal drug exposure and its possible implications for learning in the preschool and school-age population

For the past 5 years there has been an exponential increase in the use of cocaine, phenylcyclidine hydrochloride (PCP), and other central nervous system (CNS) active drugs. A significant amount of this accelerated usage is in sexually active females, resulting in some urban hospitals reporting positive drug screens in over 16% of the infants born on their busy obstetrical service. There is a growing body of data showing that fetal exposure to cocaine, phenylcyclidine hydrochloride (PCP), and other CNS-active drugs results in infants and children with abnormal brain wave patterns, short-term neurologic signs, depression of interactive behavior, and poor organizational responses to environmental stimuli. Whether such neurologic findings will translate into a significant number of children with learning and behavioral problems needs to be the focus of long-term longitudinal studies of children with fetal drug exposure to cocaine, PCP, and other CNS-active drugs.     

An analysis of the use of autobiographical narrative for teachers’ intercultural learning

The currency of intercultural education has risen worldwide in response to increased diversity within societies resulting from migration and global flows of populations. As intercultural education becomes a core responsibility of schooling, critical, detailed analysis of pedagogies for teachers’ own intercultural learning is largely absent in education research, in contrast to attention to developing students’ intercultural capabilities and theoretical and policy analyses. In beginning to address this limitation, this article offers a critical, reflexive analysis of our use and the efficacy of using autobiographical narrative for teachers’ intercultural learning. Framing theories include interculturality, autobiographical narratives for teachers’ professional learning, reflexivity, and the effects of silence and silencing in relation to diversity and intercultural relations in schools. Three instances of teacher autobiographical narrative elicited as part of a large-scale, longitudinal study of intercultural education in Australian schools are deconstructed to elucidate their explicit and hidden meanings and effects. The analysis reveals that while autobiographical narrative has productive potential as a strategy for stimulating teacher reflexivity about cultural identities and intercultural relations, it also contains hidden dangers and traps that caution against viewing it as a pedagogical cure-all in the development of teachers’ intercultural knowledge and skills.     

Being “in a Limbo”: Perceptions of Immigration,Identity and Adaptation of Immigrant Students in South Africa and the United States

Much research is available that details student experiences of immigration and adaptation to receiving countries and schools, but few studies analyze the metaphors used by immigrant students (IS) when talking about the immigration experience, or offer a comparative lens through which to view identity negotiation in two very different contexts. The present paper aims to address these gaps by conducting a comparative linguistic analysis of 20 interviews conducted with IS at universities in South Africa and the United States in order to gain a greater understanding of immigration and the types of identity negotiation processes learners undergo in these very different countries. Findings reveal interesting similarities between metaphorical conceptions of immigration across different cultural contexts and a remarkable resilience in the use of adaptation strategies and identity development that leads to salient pedagogical implications for teachers of higher education who face increasingly international classrooms.     

Staff support group on a cancer ward: a pilot project

Despite strong evidence of high stress among oncology nursing staffs, few empirical intervention studies have been attempted. This study involved a pilot project to combine two anxiety-reducing aids--group support and the provision of pertinent information--into a single format for maximum stress reduction. Weekly groups producing both support and information lasted 8 months and covered a wide range of topics. Both unstructured and didactic sessions were used. Pre- and postquestionnaires were distributed to each participant to assess ward atmosphere, attitudes about cancer, and level of stress. Participants expressed great satisfaction with the project, but their enthusiasm was not supported by statistical evaluation. Various methodological and programmatic aspects that may account for the discrepancy between anecdotal and statistical results are discussed.     

The relationship between neonatal characteristics and three-month mother-infant interaction in high-risk infants

The behavior of 4 groups of infants--healthy term, healthy preterm, sick preterm, and sick full-term--was assessed in the neonatal period using the Neonatal Behavioral Assessment Scale (NBAS). At 3 months postterm, infants and their mothers were observed and videotaped in a free-play session. Both the NBAS and mother-infant interaction data were analyzed to assess the effects of maturity (term vs. preterm), illness (sick vs. healthy), and their interaction. Results revealed that illness of the infant affected both NBAS performance and maternal behavior during the interaction at 3 moths. Infants who were ill performed poorly on the NBAS orientation dimension; this dimension was found to be significantly associated with maternal and infant behaviors at 3 months. These data demonstrate an association between early infant characteristics and subsequent mother and child interactive behaviors. They also identify postnatal illness as an important influence on the development of the mother-infant dyad.     

Developmental Relations Among Behavioral Inhibition,Anxiety, and Attention Biases to Threat and Positive Information

This study examined relations between behavioral inhibition (BI) assessed in toddlerhood (n = 268) and attention biases (AB) to threat and positive faces and maternal‐reported anxiety assessed when children were 5‐ and 7‐year‐old. Results revealed that BI predicted anxiety at age 7 in children with AB toward threat, away from positive, or with no bias, at age 7; BI did not predict anxiety for children displaying AB away from threat or toward positive. Five‐year AB did not moderate the link between BI and 7‐year anxiety. No direct association between AB and BI or anxiety was detected; moreover, children did not show stable AB across development. These findings extend our understanding of the developmental links among BI, AB, and anxiety.     

Person‐Fit Statistics for Joint Models for Accuracy and Speed

Response accuracy and response time data can be analyzed with a joint model to measure ability and speed of working, while accounting for relationships between item and person characteristics. In this study, person‐fit statistics are proposed for joint models to detect aberrant response accuracy and/or response time patterns. The person‐fit tests take the correlation between ability and speed into account, as well as the correlation between item characteristics. They are posited as Bayesian significance tests, which have the advantage that the extremeness of a test statistic value is quantified by a posterior probability. The person‐fit tests can be computed as by‐products of a Markov chain Monte Carlo algorithm. Simulation studies were conducted in order to evaluate their performance. For all person‐fit tests, the simulation studies showed good detection rates in identifying aberrant patterns. A real data example is given to illustrate the person‐fit statistics for the evaluation of the joint model.
