Exploring the Etiology of the Association Between Birthweight and IQ in an Adolescent Twin Sample

The negative effects of very low birthweight on intellectual development have been well documented, and more recently this effect has been shown to generalise to birthweights within the normal range. In this study we investigate the etiology of this relationship by using a classical twin design to disentangle the contributions of genes and environment. A previous Dutch study (Boomsma et al., 2001) examining these effects indicated that genes were important in mediating the association of birthweight to full IQ measured at ages 7 and 10, but not at ages 5 and 12. Here the association between birthweight and IQ at age 16 is considered (N = 523 twin pairs). Using variance components modeling we found that the genetic variance in birthweight (4%) completely overlapped with that in verbal IQ but not performance or full IQ. Results further showed the importance of shared environmental effects on birthweight (similar to 60%) but not on IQ (with genes explaining up to 72% of IQ variance). Models incorporating a direction of causation parameter between birthweight and IQ provided adequate fit to the data in either causal direction for performance and full IQ, but the model with verbal 10 causing birthweight was preferred to one in which birthweight influenced verbal IQ. As the measurement of birthweight precedes the measurement of twins' IQ at age 16, the influence of verbal IQ might be better considered as a proxy for parents' 10 or education, and it is possible that brighter mothers provide better prenatal environments for their children.

A Comparison of Paediatric Occupational Therapy University Program Curricula in New Zealand, Australia, and Canada

Comparisons were made of the paediatric content of professional entry-level occupational therapy university program curricula in Australia, New Zealand, and Canada using an ex post facto surveymethodology. The findings indicated that in Australia/New Zealand, paediatrics made up 20% of the total curriculum, but only 13% in Canada. Canadian reference materials were utilized less often in Canadian universities than in Australia/New Zealand. Theories taught most often in Australia/New Zealand were: Sensory Integration, Neurodevelopmental Therapy, Client-Centered Practice, Playfulness, and the Model of Human Occupation. In Canada, the most frequent theories were: Piaget’s Stages ofCognitive/Intellectual Development, Neurodevelopmental Therapy, Erikson’s Eight Stages of Psychosocial Development and Sensory Integration. The most frequently taught paediatric assessment tools in both regions were the Bruininks-Oseretsky Test of Motor Proficiency and Miller Assessment for Preschoolers. Paediatric interventionmethods taught to students in all three countries focused on activities of daily living/self-care, motor skills, perceptual and visual motor integration, and infant and child development.

Risk factors for schizophrenia. Follow-up data from the Northern Finland 1966 Birth Cohort Study

This paper updates single risk factors identified by the Northern Finland 1966 Birth Cohort Study up to the end of year 2001 or age 34. Impaired performance (e.g., delayed motor or intellectual development) or adverse exposures (e.g., pregnancy and birth complications, central nervous system diseases) are associated with an increased risk for schizophrenia. However, upper social class girls and clever schoolboys also have an increased risk to develop schizophrenia, contrasted to their peers. Individuals who subsequently develop schizophrenia follow a developmental trajectory that partly and subtly differs from that of the general population; this trajectory lacks flexibility and responsiveness compared to control subjects, at least in the early stages. We propose a descriptive, lifespan, multilevel systems model on the development and course of schizophrenia.

A INTEGRAÇÃO ORIENTE-OCIDENTE E OS FUNDAMENTOS DO JUDÔ EDUCATIVO

Desenvolvido em 1882 por Jigoro Kano a partir de seus estudos sobre as escolas de jujutsu, o Judô Kodokan surgiu dentro do espaço escolar a partir de três pilares básicos: como método de luta (arte marcial), como método de treinamento físico (educação física), como método de treinamento mental (desenvolvimento moral e intelectual) onde o Do (caminho) é o foco principal a ser ensinado em vista de beneficiar a sociedade. Uma das principais contribuições de Kano foi a transformação de uma prática de luta marcial em um método educativo. Tal processo ocorreu num momento histórico marcado por mudanças sociais no Japão que passou a receber forte influência do mundo ocidental durante a era Meiji. Naquela época os valores, pensamentos, instituições e linguagens orientais e ocidentais circulavam e se fundiam marcando um forte sincretismo em diversos espaços sociais. Teria Jigoro Kano absorvido essas influências ao desenvolver o judô? Essa possível ligação entre o Oriente e o Ocidente, preservando parte da cultura tradicional japonesa e permitindo a influência de pensamentos e práticas ocidentais, possui extrema relevância para a atualidade uma vez que muito se fala em retornar as formulações que deram origem ao Judô. Afinal, que formulações são estas e até que ponto devemos adotá-las sem uma profunda reflexão? No transcorrer da história e, mais precisamente ao final da 2ª guerra mundial, o judô perde boa parte dos conceitos e fundamentos que fazem sua ligação com a linguagem e o pensamento oriental bem como seu significado educativo original em função da sua expansão pelo mundo como prática esportiva. Assim o estudo tem como objetivos: 1) identificar os fundamentos do judô educativo segundo a influência do processo de integração Oriente-Ocidente; 2) Analisar a relação Oriente-Ocidente durante a transformação do Judô de método educativo para prática esportiva; 3) Organizar elementos estruturantes para estabelecer os fundamentos do judô educativo contemporâneo analisando a influência da integração Oriente-Ocidente nesse processo, partindo do modelo sistêmico de pensamento de Jigoro Kano ao elaborar o Judô Kodokan reorganizando suas referências conceituais a partir da Ciência da Motricidade Humana. Trata-se de um estudo teórico, de caráter bibliográfico, que se apropria da antropologia filosófica como suporte metodológico. Os resultados da pesquisa afirmam o processo de integração Oriente-Ocidente na formulação dos conceitos educativo/filosóficos do judô além das transformações dos sistemas simbólicos da luta que apontam sua evolução antropológico-filosófica, desde a prática do Bujutsu (Arte militar sec. XVII) no Japão medieval, até as perspectivas educativas contemporâneas apoiadas na Ciência da Motricidade Humana (CMH).

On waveform analysis, the adaptive task technique, and the effect of vibration on manual control skill

A re-examination of fundamental concepts and a formal structuring of the waveform analysis problem is presented in Part I. eg. the nature of frequency is examined and a novel alternative to the classical methods of detection proposed and implemented which has the advantage of speed and independence from amplitude. Waveform analysis provides the link between Parts I and II. Part II is devoted to Human Factors and the Adaptive Task Technique. The Historical, Technical and Intellectual development of the technique is traced in a review which examines the evidence of its advantages relative to non-adaptive fixed task methods of training, skill assessment and man-machine optimisation. A second review examines research evidence on the effect of vibration on manual control ability. Findings are presented in terms of percentage increment or decrement in performance relative to performance without vibration in the range 0-0.6Rms'g'. Primary task performance was found to vary by as much as 90% between tasks at the same Rms'g'. Differences in task difficulty accounted for this difference. Within tasks vibration-added-difficulty accounted for the effects of vibration intensity. Secondary tasks were found to be largely insensitive to vibration except secondaries which involved fine manual adjustment of minor controls. Three experiments are reported next in which an adaptive technique was used to measure the % task difficulty added by vertical random and sinusoidal vibration to a 'Critical Compensatory Tracking task. At vibration intensities between 0 - 0.09 Rms 'g' it was found that random vibration added (24.5 x Rms'g')/7.4 x 100% to the difficulty of the control task. An equivalence relationship between Random and Sinusoidal vibration effects was established based upon added task difficulty. Waveform Analyses which were applied to the experimental data served to validate Phase Plane analysis and uncovered the development of a control and possibly a vibration isolation strategy. The submission ends with an appraisal of subjects mentioned in the thesis title.

Students' recollections of participating in a first year residential learning community experience

The purpose of this qualitative study was to gain an understanding of what participation in a first year residential learning community meant to students 2–3 years after their involvement in the program. Various theories including environmental, student involvement, psychosocial and intellectual, were used as a framework for this case study. Each of the ten participants was a junior or senior level student at the time of the study, but had previously participated in a first year residential learning community at Florida International University. The researcher held two semi-structured interviews with each participant, and collected data sheets from each. ^ The narrative data produced from the interviews were transcribed, coded and analyzed to gain insights into the experiences and perspectives of the participants. Member checking was used after the interview process. A peer reviewer offered feedback during the data analysis. The resulting data was coded into categories, with a final selection of four themes and 15 sub-themes, which captured the essence of the participants' experiences. The four major themes included: (a) community, (b) involvement, (c) identity, and (d) academics. The community theme is used to describe how students perceived the environment to be. The involvement theme is used to describe the students' participation in campus life and their interaction with other members of the university community. The identity theme is used to describe the students' process of development, and the personal growth they underwent as a result of their experiences. The academics theme refers to the intellectual development of students and their interaction around academic issues. ^ The results of this study showed that the participants valued greatly their involvement in the First Year Residents Succeeding Together program (FYRST) and can articulate how it helped them succeed as students. In describing their experience, they most recall the sense of community that existed, the personal growth they experienced, the academic development process they went through, and their involvement, both with other people and with activities in their community. Recommendations are provided for practice and research, including several related to enhancing the academic culture, integrating faculty, utilizing peer influence and providing further opportunities to create a seamless learning environment. ^

The Images of Democracy: Tocqueville and American Exceptionalism

This thesis addresses how Alexis de Tocqueville’s political thought is related to American Exceptionalism. First, I illustrate the multiple meanings of the concept of American Exceptionalism and in what sense it is indebted to Tocqueville. Second, I articulate how the historical background and personal qualities of Tocqueville contribute to the success of his masterpiece Democracy in America. In the main part, by analyzing Tocqueville’s Democracy in America and other writings on America, I argue that he indeed reveals America as exceptional and increasingly recognizes this idea through a process of intellectual development. An elaboration on Tocqueville’s theoretical contribution to the discussion of American Exceptionalism can reveal the different images of modern democracy as he suggests and how they would influence the prospect of human freedom.

Analyse multidimensionnelle de la persévérance aux études universitaires de premier cycle

L’abandon des études universitaires a attiré l’attention de plusieurs chercheurs. Toutefois, il est difficile de saisir la persévérance dans sa globalité à cause de sa complexité et le nombre important des facteurs associés. La persévérance aux études est liée aux facteurs individuels, aux facteurs contextuels et à la situation financière au cours des études. Ces facteurs ont été étudiés séparément et d’une manière isolée, et aucune étude n’a, à notre connaissance, tenté de mettre ces facteurs simultanément dans un même modèle. Dans cette thèse, nous identifions les principaux déterminants de la persévérance, tout en nous appuyant sur le modèle des attentes et des valeurs (Eccles et al., 1983), le modèle interactionnel de Tinto (1975) et les modèles d’impact financier (Paulsen & St. John, 1997; St. John, 1990; St. John et al., 1994). Cette thèse a pour objectif de valider un modèle de persévérance aux études universitaires de premier cycle. Celle-ci comporte deux études. Une étude rétrospective qui permet d’évaluer, à partir de l’expérience antérieure des étudiants (n = 731), les principaux facteurs qui ont joué un rôle sur le plan de la persévérance ou de l’abandon des études. Une étude prospective suivant sur une période de six mois (deux temps de mesure) des étudiants inscrits dans un programme de baccalauréat à l’Université Laval (n = 3 084). Pour les résultats de l’étude rétrospective, la situation financière, les performances scolaires antérieures et le fait d’avoir effectué des études préuniversitaires au Cégep prédisent la persévérance. Pour le premier temps de mesure de l’étude prospective, la perception de compétence, les attentes de succès et l’intérêt prédisent l’intention de persévérer. Deux facteurs interactionnels prédisent l’intention de persévérer à savoir : les interactions avec les pairs et l’engagement institutionnel et universitaire. En ce qui concerne le deuxième temps de mesure de l’étude prospective, l’intention de persévérer, la préoccupation de la Faculté par rapport à l’enseignement et au développement des étudiants, le développement intellectuel et académique ainsi que le fait d’avoir fait des études préuniversitaires au Cégep prédisent la persévérance. Les implications théoriques, méthodologiques et pratiques sont abordées et des pistes de recherches futures sont proposées.

Reflective judgment vs. investigation of things – a comparative study of Kant and Zhu Xi

This thesis is devoted to studying two historical philosophical events that happened in the West and the East. A metaphysical crisis stimulated Kant’s writings during his late critical period towards the notion of the supersensible. It further motivated a methodological shift and his coining of reflective judgment, which eventually brought about a systemic unfolding of his critical philosophy via Kantian moral teleology. Zhu Xi and his Neo-Confucian contemporaries confronted a transformed intellectual landscape resulting from the Neo-Daoist and Buddhist discourses of “what is beyond the form”. The revival of Confucianism required a method in order to relocate the formless Dao back into daily life and to reconstruct a meta-ethical foundation within a social context. This led to the Neo-Confucian recasting of “investigation of things” from The Great Learning via complex hermeneutic operations. By the respective investigation on, as well as the comparative analysis of the two events, I reveal the convergence and incommensurability between the two distinct cultural traditions concerning the metaphysical quests, the mechanism of intellectual development, and moral teleology, so as to capture the intrinsic characteristics of philosophical research in general.

Access to knoledge in Brazil: new research on intellectual property, innovation and development

The present volume is the fruit of a research initiative on Access to Knowledge begun in 2004 by Yochai Benkler, Eddan Katz, and myself. Access to Knowledge is both a social movement and an approach to international and domestic policy. In the present era of globalization, intellectual property and information and communications technology are major determinants of wealth and power. The principle of access to knowledge argues that we best serve both human rights and economic development through policies that make knowledge, knowledge-creating tools, and nowledgeembedded goods as widely available as possible for decentralized innovation and use. Open technological standards, a balanced approach to intellectual property rights, and expansion of an open telecommunications infrastructure enable ordinary people around the world to benefit from the technological advances of the information age and allow them to generate a vibrant, participatory and democratic culture. Law plays a crucial role in securing access to knowledge, determining whether knowledge and knowledge goods are shared widely for the benefit of all, or controlled and monopolized for the benefit of a few.
