Infants at risk for autism : a European perspective on current status, challenges and opportunities
Get PDFCurrently, autism cannot be reliably diagnosed before the age of 2 years, which is why longitudinal studies of high-risk populations provide the potential to generate unique knowledge about the development of autism during infancy and toddlerhood prior to symptom onset. Early autism research is an evolving field in child psychiatric science. Key objectives are fine mapping of neurodevelopmental trajectories and identifying biomarkers to improve risk assessment, diagnosis and treatment. ESSEA (Enhancing the Scientific Study of Early Autism) is a COST (European Cooperation in Science and Technology) Action striving to create a European collaboration to enhance the progress of the discovery and treatment of the earliest signs of autism, and to establish European practice guidelines on early identification and intervention by bringing together European expertise from cognitive neuroscience and clinical sciences. The objective of this article is to clarify the state of current European research on at-risk autism research, and to support the understanding of different contexts in which the research is being conducted. We present ESSEA survey data on ongoing European high-risk ASD studies, as well as perceived challenges and opportunities in this field of research. We conclude that although high-risk autism research in Europe faces several challenges, the existence of several key factors (e.g., new and/or large-scale autism grants, availability of new technologies, and involvement of experienced research groups) lead us to expect substantial scientific and clinical developments in Europe in this field during the next few years
At the cross-roads of participatory research and biomarker discovery in autism: the need for empirical data
No full textIdentifying biomarkers for autism can improve outcomes for those affected by autism. Engaging the diverse stakeholders in the research process using community-based participatory research (CBPR) can accelerate biomarker discovery into clinical applications. However, there are limited examples of stakeholder involvement in autism research, possibly due to conceptual and practical concerns. We evaluate the applicability of CBPR principles to biomarker discovery in autism and critically review empirical studies adopting these principles
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Autism and the social brain: the first year puzzle
No full textThe atypical features of social perception and cognition observed in individuals diagnosed with autism have been explained in two different ways. First, domain-specific accounts are based on the assumption that these end-state symptoms result from specific impairments within component structures of the ‘social brain network’. Second, domain-general accounts hypothesize that rather than being localized, atypical brain structure and function is widespread, or that the apparent social brain differences are the consequence of adaptations to an earlier occurring widespread changes in brain function. Critical evidence for resolving this basic issue comes from prospective longitudinal studies of infants at-risk for later diagnosis. We highlight selected studies from the newly emerging literature on infants at familial risk for autism to shed light on this issue. Despite multiple reports of possible alterations in brain function in the first year of life, overt behavioral signs do not emerge until the second year. Our review reveals only mixed support, within this very early period, for localized deficits in social brain network systems, and instead favors the view that atypical development involving perceptual, attentional, motor, and social systems precede the emerging autism phenotype
The contribution of developmental models toward understanding gene-to-behavior mapping: the case of Williams Syndrome
No full textBook synopsis: An essential, comprehensive resource for researchers, as well as for graduate and undergraduate teaching programs
Takes care to consider the "whole person" in addition to discussing the disability
Focuses on understanding development within the framework of specific populations, such as those of persons with Down, fragile, X, Williams, and other syndromes
Part of THE OXFORD LIBRARY OF PSYCHOLOGY
Though the tremendous amount of recently-emerged developmentally-oriented research has produced much progress in understanding the personality, social, and emotional characteristics of persons with intellectual disabilities (ID), there is still much we don't know, and the vast task of precisely charting functioning in all these areas, while also identifying the associated fine-tuned, complex, and intertwined questions that crop up along the way, seems daunting and insurmountable.
The goal of The Oxford Handbook of Intellectual Disability and Development is to update the field with new, precise research and sophisticated theory regarding individuals with ID provided by seasoned developmental theorists who have made original conceptual contributions to the field. This volume is divided into five general sections (ID and its connection to genetics, relationships, cognitive development, socio-emotional development, and development of language), with each focused on a domain of functioning or aspect of life that is inherent to an integrated, transactional perspective of development. While developmental approaches to understanding persons with intellectual disability will continue to emerge, this comprehensive volume is a must-read for specialists and developmental psychologists who must have the conceptual foundations for examining the developmental trajectories across persons with any of the many different ID etiologies
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
