Immigrant–Native Differences in Child Health: Does Maternal Education Narrow or Widen the Gap?

Abundant U.S. research documents an “immigrant advantage” in children’s physical health. This article extends consideration to the United Kingdom, permitting examination of a broader group of immigrants from disparate regions of the world and different socioeconomic backgrounds. Drawing on birth cohort data (ages 0–5) from both countries (n = 4,139 and n = 13,381), the analysis considers whether the children of immigrants have a physical and mental health advantage around the beginning of elementary school, and whether advantage is more pronounced among low‐educated populations. Findings indicate that the children of immigrants are not uniformly healthier than those in native‐born families. Rather, there is heterogeneity in the immigrant advantage across outcomes, and evidence of both greater advantage and disadvantage among children in low‐educated immigrant families.     

Making mathematical meaning through dialogue: ``Once you think of it, the Z minus three seems pretty weird'

In our ongoing qualitative classroom research, we adopt a sociocultural perspective to investigate discourse, and its role in how children and teachers make meaning of mathematics in a fifth grade inquiry classroom. Our theoretical perspective draws primarily on Vygotsky (1978, 1986) and Bakhtin (1981, 1986) each of whom examines how social forms of meaning influence individual cognition. The episode described in this paper examines the process whereby individual and group developmental trajectories are constructed, and allows us to explore the relationship between discourse and knowing. We combine a longitudinal design with a case study approach to focus on the collaborative mathematical problem solving. We use video capture to help us listen to children's discussions in classroom activities and small group interactions. Our analysis of the verbal data recorded on video identifies patterns of interaction, development and change in participants' use of mathematical language and concepts, and their evolving understanding, through discussion and argument, of an algebraic expression constructed by one of the children. The findings lead us to argue for i) a more generative view of the zone of proximal development as a site of learning and of identity formation, ii) an expanded view of the role of the teacher in inquiry classrooms, and iii) an appreciation for the valuable roles difference and resistance play in knowledge building.     

Immediate shock,passive avoidance,and potentiated startle: Implications for the unconditioned response to shock

Three experiments were performed to study the immediate-shock freezing deficit, a deficit in freezing in rats that results when electric shock is delivered immediately upon exposure to a novel context. This deficit was accompanied by failures to detect evidence of passive avoidance (Experiment 1) or potentiation of the auditory startle response (Experiment 2). The deficit in freezing was attenuated by preexposure to the shocked context (Experiment 3). The results support the view that fear-related behaviors are activated by signals for shock rather than by shock itself. They also suggest that the immediate-shock freezing deficit is due to a failure to process the to-be-conditioned contextual cues (Fanselow, 1986a, 1990).     

Developing a global dimension in the curriculum

Jaya Graves trained as a Rudolph Steiner teacher. She also worked extensively with the peace movement through the 1970s and 80s. She is now co-ordinator of Southern Voices, a small organization in Manchester committed to presenting views, perspectives and voices of people from Southern or ‘developing’ countries in different contexts where development education (DE) is practised and ‘developing’ issues are discussed. Implicit in this aim is the understanding that many ‘developing’ countries are ‘root cultures’ to children in an intercultural society. An understanding of ‘developing’ countries and issues will, therefore, help us understand our own society as well as the world in which we live.     

Criteria for evaluating alternative MEDLINE search engines

With so many options available for searching MEDLINE on the World Wide Web or as a component of an online service, evaluation criteria are suggested as a means of assisting librarians in determining the positive and negative aspects of alternative MEDLINE sites. A set of searches was utilized to systematically compare MEDLINE sites. Sites evaluated included Avicenna, America Online, HealthGate, PubMed, Medscape, and Physicians' Online. Some features used to evaluate these sites were: default fields; operators (default); access to MeSH; subheadings; stop words protected in MeSH; truncation; and stemming. This article will describe the group process used to arrive at the evaluation criteria, as well as some general conclusions which will help librarians in directing their users to a particular MEDLINE site.
