Interrupting the child/adult dichotomy: A genealogy of genius as an administrative object in educational discourse

Part of a special issue on childhood and cultural studies. The writer provides a genealogy of genius that interrupt the child/adult dichotomy and disrupts the notion of child as subject. Tracing the evolution of the notion of “genius,” she notes that although conceptualizations of genius have changed considerably over the years, it has continually been a concept that distinguishes the haves from the have-nots. The writer maintains that the idea of genius consistently invokes images of both maleness and whiteness and marginalizes the experiences of women and other groups.

Interaction of adult human neural crest-derived stem cells with a nanoporous titanium surface is sufficient to induce their osteogenic differentiation

Osteogenic differentiation of various adult stem cell populations such as neural crest-derived stem cells is of great interest in the context of bone regeneration. Ideally, exogenous differentiation should mimic an endogenous differentiation process, which is partly mediated by topological cues. To elucidate the osteoinductive potential of porous substrates with different pore diameters (30 nm, 100 nm), human neural crest-derived stem cells isolated from the inferior nasal turbinate were cultivated on the surface of nanoporous titanium covered membranes without additional chemical or biological osteoinductive cues. As controls, flat titanium without any topological features and osteogenic medium was used. Cultivation of human neural crest-derived stem cells on 30 nm pores resulted in osteogenic differentiation as demonstrated by alkaline phosphatase activity after seven days as well as by calcium deposition after 3 weeks of cultivation. In contrast, cultivation on flat titanium and on membranes equipped with 100 nm pores was not sufficient to induce osteogenic differentiation. Moreover, we demonstrate an increase of osteogenic transcripts including Osterix, Osteocalcin and up-regulation of Integrin β1 and α2 in the 30 nm pore approach only. Thus, transplantation of stem cells pre-cultivated on nanostructured implants might improve the clinical outcome by support of the graft adherence and acceleration of the regeneration process.

Playful structure: a novel image of early years pedagogy for primary school classrooms

Playful structure is a new pedagogic image representing a more balanced and integrated perspective on early years pedagogy, aiming to blend apparent dichotomies and contradictions and to sustain and evolve play-based practice beyond Year 1. Playful structure invites teachers and children to initiate and maintain a degree of playfulness in the child’s whole learning experience, even when the learning intentions demand a supportive structure. Thus, playfulness becomes characteristic of the interaction between adult and the child and not just characteristic of child-initiated versus adult-initiated activities, or of play-time versus task-time. The paper is based on intensive observations and interviews with teachers in Northern Ireland who participated in a play-based and informal curriculum. This paper explains how playful structure rests on complementary processes of infusion of structure into play-based activities and infusion of playfulness into more structured activities, illustrated by cameos. ‘Infusion’ suggests the subtle blending process that allows apparent dichotomies and contradictions to be resolved in practice.

Child-centred design supported by comprehensive child application use analysis

Since children already use and explore applications on smartphones, we use this as the starting point for design. Our monitoring and analysis framework, BaranC, enables us to discover and analyse which applications children uses and precisely how they interact with them. The monitoring happens unobtrusively in the background so children interact normally in their own natural environment without artificial constraints. Thus, we can discover to what extent a child of a particular age engages with, and how they physically interact with, existing applications. This information in turn provides the basis for design of new child-centred applications which can then be subject to the same comprehensive child use analysis using our framework. The work focuses on the first aspect, namely, the monitoring and analysis of current child use of smartphones. Experiments show the value of this approach and interesting results have been obtained from this precise monitoring of child smartphone usage.

Impacto del Programa de Alimentación Escolar en el Trabajo Infantil: Una aproximación desde la toma de decisiones familiares

Esta investigación analiza el impacto del Programa de Alimentación Escolar en el trabajo infantil en Colombia a través de varias técnicas de evaluación de impacto que incluyen emparejamiento simple, emparejamiento genético y emparejamiento con reducción de sesgo. En particular, se encuentra que este programa disminuye la probabilidad de que los escolares trabajen alrededor de un 4%. Además, se explora que el trabajo infantil se reduce gracias a que el programa aumenta la seguridad alimentaria, lo que consecuentemente cambia las decisiones de los hogares y anula la carga laboral en los infantes. Son numerosos los avances en primera infancia llevados a cabo por el Estado, sin embargo, estos resultados sirven de base para construir un marco conceptual en el que se deben rescatar y promover las políticas públicas alimentarias en toda la edad escolar.

Life of children exposed to alcohol or drugs in utero This study focused on the growth environment, physical development and socio-emotional development of children, aged 16 and under, who had been exposed to alcohol (n=78) or drugs (n=15) in utero. The aim of the study was to obtain a comprehensive picture of the living conditions of these children and to examine the role of the growth environment in their development. The study was carried out using questionnaires, written life stories and interviews. Attachment theory was used as a background theory in the study. Over half of the children exposed to alcohol were diagnosed with foetal alcohol syndrome (FAS), one quarter was diagnosed with foetal alcohol effects (FAE), and one fifth had no diagnosis. Most of the children exposed to drugs had been exposed to either amphetamines or cannabis, and a smaller number to heroin. Some of the children exposed to alcohol were mentally handicapped or intellectually impaired. The children exposed to drugs did not exhibit any serious learning difficulties but a considerable number of them had socio-emotional development problems. Language and speech problems and attention, concentration and social interaction problems were typical among both the children exposed to alcohol and those exposed to drugs. Only one child had been placed into long-term foster care in a family immediately after leaving the maternity hospital. In biological families there had been neglect, violence, mental health problems, crime and unemployment, and many parents were already dead. Two of the children had been sexually abused and four were suspected of having been abused. From the point of view of the children's development, the three most critical issues were 1) the range of illnesses and handicaps that had impaired their functional capacity as a result of their prenatal exposure to alcohol, 2) child's age at the time of placement on a long-term basis, and 3) the number of their traumatic experiences. The relationship with their biological parents after placement also played a role. Children with symptoms were found in all diagnosis categories and types of exposure. Children with the smallest number of symptoms were found among those who had never lived with their biological parents. Almost all children were exhibiting strong symptoms at the time of placement in foster care. In most cases, they were behaving in a disorderly manner towards others, but some children were withdrawn. The most conspicuous feature among those with the most severe symptoms was their disorganized behaviour. Placement in a foster family enhanced the children's development, but did not solve the problems. The foster parents who brought these children up did not receive as much therapy for the children and support for the upbringing as they appear to have needed. In Finland, transfer to long-term custody is based on strict criteria. The rights of children prescribed in the child protection law are not fulfilled in practice.

Étude électrophysiologique de la suppression interoculaire : implication pour l'amblyopie

L’amblyopie est un trouble développemental de la vision binoculaire. Elle est typiquement caractérisée par des atteintes de l’acuité visuelle et de la stéréoscopie. Toutefois, de plus en plus d’études indiquent la présence d’atteintes plus étendues telles que les difficultés d’attention visuelle ou de lecture. L’amblyopie est généralement expliquée par une suppression interoculaire au niveau cortical, considérée comme chronique ou permanente à l’extérieur de la période développementale. Or, un nombre croissant d’études suggèrent que des interactions binoculaires normales seraient présentes chez les amblyopes adultes. Dans une première étude, nous avons tenté d’identifier un marqueur électrophysiologique de la vision binoculaire. Nous avons enregistré des potentiels évoqués visuels chez des observateurs normaux à qui l’on a induit une dysfonction binoculaire. Les interactions binoculaires étaient caractérisées à l’aide de patrons (facilitation, moyennage et suppression) en comparant les réponses monoculaires et binoculaires. De plus, ces interactions étaient quantifiées à partir d’index d’intégration continus en soustrayant la somme des réponses monoculaires de la réponse binoculaire. Les résultats indiquaient que les patrons d’interaction n’étaient pas optimaux pour estimer les performances stéréoscopiques. Ces dernières étaient, en revanche, mieux expliquées par notre index d’intégration binoculaire. Ainsi, cette étude suggère que l’électrophysiologie est un bon prédicteur de la vision binoculaire. Dans une deuxième étude, nous avons examiné les corrélats neuronaux et comportementaux de la suppression interoculaire chez des amblyopes adultes et des observateurs normaux. Des potentiels évoqués visuels stationnaires ont été enregistrés en utilisant un paradigme de suppression par flash. La suppression était modulée par un changement de contraste du stimulus flash (10, 20, 30, ou 100%), ou le suppresseur, qui était présenté soit dans l’œil dominant ou non-dominant (ou amblyope). Sur le plan comportemental, la suppression interoculaire était observée indépendamment de l’œil stimulé par le flash chez les contrôles. Au contraire, chez les amblyopes, la suppression était asymétrique (c’est-à-dire supérieure lorsqu’elle provenait de l’œil dominant), ce qui suggérait une suppression chronique. De manière intéressante, l’œil amblyope a supprimé l’œil dominant à haut niveau de contraste. Sur le plan électrophysiologique, l’effet de suppression interoculaire observé à la région occipitale était équivalent dans chaque groupe. Toutefois, les réponses électrophysiologiques à la région frontale chez les amblyopes n’étaient pas modulées comme celles des contrôles; la suppression de l’œil amblyope était manifeste même à bas contraste. Nous résultats supportent ainsi l’existence d’interaction binoculaire fonctionnelle chez les amblyopes adultes ainsi que l’implication d’un réseau cortical étendu dans la suppression interoculaire. En somme, l’amblyopie est une condition complexe dont les atteintes corticales et les déficits fonctionnels semblent globaux. L’amblyopie ne doit plus être considérée comme limitée à une dysfonction de l’aire visuelle primaire. La suppression interoculaire semble un point central de cette problématique, mais encore beaucoup d’études seront nécessaires afin de déterminer l’ensemble des mécanismes impliqués dans celle-ci.
