Using Research to Improve the Cost Effectiveness of Early Intervention Programs

Since the implementation of Public Law 99457, the number of children served by early intervention programs has increased substantially. This article describes the d e s of advocacy and science in contributing to that expansion. A biosocial systems model of early development is used to explain how comparative experimental research can help to improve the cost effectiveness of early intervention programs. Examples of the benefits of such research are taken from the other articles reported in this issue of Early Education and Development.     

Toronto multiagency child abuse research project: The abused and the abuser

Information from 422 cases of child mistreatment in Toronto was gathered from the files of a child welfare agency and a children's hospital. These data were compared to patterns reported in previous studies and clinical writings on child mistreatment to investigate similarities and differences in families whose children have been abused in Canada, England, and the United States. Findings from the present study were similar to others in many respects. The differences were primarily in the area of lower incidences of such problems as perinatal difficulties in the children and intellectual limitations and social isolation in the parents; however, there was a higher incidence of single-parent families. The results suggest that clinicians should bear in mind that child mistreatment cannot be ruled out on the grounds that no serious problems have been noted for the child or the family.     

Temperament, Emotion, and Cognition at Fourteen Months: The MacArthur Longitudinal Twin Study

200 pairs of twins were assessed at 14 months of age in the laboratory and home. Measures were obtained of temperament, emotion, and cognition/language. Comparisons between identical and fraternal twin correlations suggest that individual differences are due in part to heritable influences. For temperament, genetic influence was significant for behavioral observations of inhibition to the unfamiliar, tester ratings of activity, and parental ratings of temperament. For emotion, significant genetic influence was found for empathy and parental ratings of negative emotion. The estimate of heritability for parental report of expression of negative emotions was relatively high, whereas that for expression of positive emotions was low, a finding consistent with previous research. For cognition and language, genetic influence was significant for behavioral indices of spatial memory, categorization, and word comprehension. Shared rearing environment appears influential for parental reports of language and for positive emotions, but not for other measures of emotion or for temperament.     

Educating and training out of poverty? Adult provision and the informal sector in fishing communities,South Africa

This paper looks at access to adult education and vocational education and training (VET) provision in fishing communities in the Western Cape, South Africa. Fishing communities are being disadvantaged due to geographical and socio-political marginalisation, and the predominance of informal sector employment in the context of worldwide marine resource depletion. Neither public nor private provision is adequately serving rural areas or the informal sector in this context. Using the sustainable livelihoods approach as a tool of analysis, this paper argues that a more cross-sectoral approach is needed to tackle equity and poverty concerns in adult education and training provision.     

Education and colonial language policies in Latin America and the Caribbean

In Latin America governmental responses to the language issue have ranged from suppression of non-European languages to active promotion of at least a limited bilingualism. The thesis of this article is that the inconsistencies are primarily a function of economic and social struggles among contending national elites with the common goal of compelling subordinate groups to adapt to the behaviors and expectations of the elite groups. Not until the nineteenth century witnessed a shift to capital-intensive modes of production did the schools become a major locus for implementation of governmental policy. Then the schools were called upon in a direct and massive way to augment traditional forms of social control.

Zusammenfassung In Latein-Amerika reichte die Reaktion der Regierungen auf sprachliche Probleme von der Unterdrückung nicht-europäischer Sprachen bis zur aktiven Förderung wenigstens einer begrenzten Zweisprachigkeit. Dieser Artikel vertritt den Standpunkt, die Gegensätze seien hauptsächlich bedingt durch wirtschaftliche und soziale Kämpfe zwischen wetteifernden nationalen Führungsschichten, die alle das gleiche Ziel verfolgen, untergeordnete Gruppen zu zwingen, die Verhaltensweisen und Erwartungen der Führungsgruppen zu übernehmen. Erst als sich das 19. Jahrhundert allmählich auf kapital-intensive Produktionsweisen umstellte, wurden die Schulen in höherem Masse Zuchtstätten der Regierungspolitik. Danach wurden sie unmittelbar und massiv aufgerufen, traditionelle Formen der Gesellschaftskontrolle zu verstärken.

Résumé En Amérique Latine les réponses gouvernementales à la question du langage sont passées d'une suppression des langages non-européens à leur promotion active, ou du moins à un certain bilingualisme. La thèse de cet article est que ces inconséquences sont avant tout fonction des luttes économiques et sociales entre les élites nationales en présence dont le but commun est de contraindre les groupes subordonnés à s'adapter à leurs manières d'être et à leurs expectations. Ce n'est qu'après que le dixneuvième siècle ait été le témoin d'un glissement vers des méthodes de production à haute teneur en capitaux que les écoles sont devenues le locus principal de mise en oeuvre de la politique gouvernementale. On a eu, alors, recours aux écoles d'une façon directe et massive pour augmenter les formes traditionnelles de contrôle social.

     

Gardnerella vaginalis infection and sexual contact in female children

Gardnerella vaginalis (GV) infection has been reported as being acquired via sexual contact in adults and as an indicator of sexual contact in female children (DeJong, 1985). The purpose of this study was to determine if GV infection was more commonly found in 191 female children who gave a history of sexual contact and/or were infected with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) (Group 1), compared with 144 female children evaluated for possible sexual abuse and found to have no such history or infection with GC or CT (Group 2), or 31 female children (friends of the authors) without such a history or GC or CT infection (Group 3). Vaginal GV was found in 5.3% of Group 1, 4.9% of Group 2 and 6.4% of Group 3 (p > .05). Also, vaginal GV infection was not related to the type of sexual contact or race, but did increase with age in white female children. Because vaginal GV infection is not more commonly found in children with a history of sexual contact than those without such a history, the finding of GV in a vaginal culture in an individual case would not be a reliable marker of sexual contact. Routine culturing for GV is not recommended as part of a sexual abuse workup.     

Contextual Variation and Memory Retrieval at Six Months

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed.     

Ureaplasma urealyticum and large colony mycoplasma colonization in female children and its relationship to sexual contact, age, and race.

In order to determine if Ureaplasma urealyticum (Uu) or large colony mycoplasma (LCM) colonization was related to a history of sexual abuse, the type of sexual contact, an enlarged vaginal introitus transverse diameter (greater than 4 mm), age or race, 452 female children, ages 1-12 years, were evaluated by the Child Sexual Abuse Team at Wake Medical Center in Raleigh, NC. Thirty-six girls were deleted because of inadequate cultures. When controlled for race and age, Uu throat (T), vaginal (V), and rectal (R) colonization and LCM vaginal and rectal colonization were not related to any of the other variables listed above. The enlarged vaginal introital diameter was related to a history of sexual abuse (p less than .001). Uu and LCM vaginal colonization rates were increased in black girls as compared to white girls (p less than .05). Uu V, Uu R, LCM V, and LCM R colonization increased with age. In our study population, Uu and LCM colonization was not a useful marker of sexual contact.     

Children's Judgments about Psychological Harm in Social Context

72 children, ages 6 to 11 years, were presented with a series of stories involving psychological harm (name-calling) in a game context. Situations were presented in which intentions, consequences, and game context were varied, along with order of story presentation. Comparisons between acts of physical and psychological harm were also conducted. Although responses in some conditions were influenced by order of presentation, age differences were found in children's evaluations of agents' actions and recipients' reactions for psychological harm in game contexts. Younger children were more likely to ignore intentions and consequences or the recipient's perspective and to focus on contextual features (e.g., game rules). Older children were more likely to base their evaluations on intentions, or both intentions and consequences, and to take into account the recipient's perspective. Game context interacted differentially with psychological and physical harm at all ages. Evaluations of acts of physical harm were more likely than acts of psychological harm to be transformed by game context.
