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
Autism and Down Syndrome: An Examination of the Baby and Infant Screen for Autism Traits in Toddlers with Down syndrome
Get PDFCurrent research suggests that children with Down Syndrome (DS) are at an increased risk for autism spectrum disorder (ASD) compared to the general population. Detecting ASD early in children with DS is crucial to providing access to additional treatment services and supports that may be necessary. Despite a critical need to identify ASD as early as possible, diagnoses of ASD are often delayed in individuals with DS. It can be especially difficult for clinicians to differentiate between symptoms attributed to intellectual developmental disorder (IDD), a primary feature of DS, and possible ASD symptoms. Only two research studies have evaluated the psychometric properties of ASD screening measures in individuals with DS, though neither of these studies included individuals with DS under the age of 3 years old. Therefore, this study sought to expand current literature by evaluating the factor structure of the Baby Infant Screen for Children with aUtIsm Traits (BISCUIT) in 186 toddlers diagnosed with DS as compared to 187 toddlers diagnosed with cerebral palsy (CP) aged 17 to 35 months. Additionally, the impact of diagnostic group on the frequency at which caregivers endorsed BISCUIT items, ASD symptomology, and clinician-rated communication and cognition scores on the Battelle Developmental Inventory, 2nd Edition (BDI-2) were investigated. Results indicated that a four-factor solution fit the DS sample best, while a three-factor solution fit the CP sample best. Congruence coefficients resulted in one factor (i.e., verbal communication) with good similarity between the factor loadings for the DS and CP groups. Toddlers with DS were found to demonstrate significantly less impairment than toddlers with CP across two BISCUIT composites (i.e., nonverbal communication/socialization, restricted interests/repetitive behaviors); however, toddlers with DS demonstrated significantly more impaired communication scores on the BDI-2 and their caregivers more frequently endorsed difficulties with verbal communication on individual BISCUIT items. Implications for ASD screening of children with DS, as well as recommendations for future research and clinical practices 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
Developmental Functioning of Infants and Toddlers with Autism and Down Syndrome
Get PDFAutism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, as well as restricted interests and repetitive behaviors. Approximately 10% of individuals with ASD also have comorbid genetic or chromosomal conditions, like Down Syndrome (DS). While it was once believed that DS and ASD rarely co-occurred, it has been demonstrated that it is not uncommon for children with DS to also meet criteria for ASD. Due to the difficulties in differentiating between impairments associated with intellectual disability (ID) and ASD symptomology, DS often leads to delayed or misdiagnoses of ASD. This can interfere with early intervention services and appropriate educational placements. While prior research has compared developmental functioning in children with ASD and DS, no studies have examined the impact of ASD risk and DS on developmental functioning in infants and toddlers under the age of 3. Utilizing the Baby and Infant Screen for Children with aUtIsm Traits-Part 1 (BISCUIT-Part 1) and the Battelle Developmental Inventory, Second Edition (BDI-2), the current study aimed to expand the existing literature by investigating the effects of ASD risk and DS on developmental functioning in infants and toddlers. The current study compared three groups consisting of 46 toddlers each: ASD screen positive only without co-occurring DS (ASD+), DS screen negative (DS-), and DS screen positive (DS+). The results of the current study revealed significant group differences in the overall developmental functioning, as well as each developmental subdomain of the BDI-2. These findings support the need for early screening and identification of ASD among those with genetic conditions
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
