Mathematical skills and working memory profile of children with borderline intellectual functioning
Borderline intellectual functioning is a neurodevelopmental condition characterized by an intelligence quotient (IQ) in the range of 70-85. The present study aimed to investigate the mathematical abilities and the working memory of students with borderline intellectual functioning (BIF). The sample group included 10 year-old students with BIF ( n = 85) and with average non-verbal IQ ( n = 45). The children were assessed in non-verbal intelligence, numerical ability and working memory. Our results showed an impairment of mathematical skills, especially in the operation tasks, and working memory in children with BIF, compared to typically developing peers. Generally, their skills seemed to be consistent with intelligence scores (WOND and AWMA scores ≥ 70). In some cases, children with BIF could have mathematical difficulties (WOND < 70). In general, they showed visuospatial short-term memory and central executive subsystem more damaged than non-verbal intelligence while the verbal short-term memory was similar to the IQ

Working memory and intellectual disabilities
Intellectual disability (ID) is a neurodevelopmental disorder that begins in childhood, characterised by intellectual and adaptive functioning deficits in conceptual (language, reading, maths, reasoning, knowledge, memory), social (empathy, friendships, interpersonal communication skills, social judgement), and practical (personal care, money management, organising school tasks) domains (DSM-5: American Psychiatric Association, 2013). ID has been described as ‘the most common developmental disorder and the most handicapping of the disorders beginning in childhood’ (Harris, 2006, p. 79), and DSM-5 requires three criteria to be met for a diagnosis of ID:
Deficits in intellectual functioning (reasoning, problem solving, Working Memory, planning, abstract thinking, judgement, academic learning, learning from experience, practical understanding) in one or more skill domains (conceptual, social, practical) that are confirmed by clinical evaluation and individualised, standardised intelligence testing. This is defined as per formance levels that are two or more standard deviations below the general population (i.e. scores of less than 70) on psychometrically sound and valid, comprehensive and culturally appropriate tests.
Deficits in adaptive functioning that significantly hamper the ability to meet developmental and sociocultural standards for personal independence and social responsibility. In practice, the adaptive deficits limit functioning in one or more activities of daily life, such as communication, social participation and independent living, and across multiple environments, such as home, school, work and recreation. Adaptive functioning deficits are assessed using clinical evaluation and individualised, culturally appropriate, psychometrically sound measures. Standardised measures can be used with knowledgeable informants (e.g., parent or other family member, teacher, care provider) and the individual if possible.
The onset of these difficulties is during the childhood period
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
Assessing working memory in Spanish-speaking children: Automated Working Memory Assessment battery adaptation
The Automated Working Memory Assessment battery was designed to assess verbal and visuospatial passive and active working memory processing in children and adolescents. The aim of this paper is to present the adaptation and validation of the AWMA battery to Argentinean Spanish-speaking children aged 6 to 11. years. Verbal subtests were adapted and pilot tested on a small sample (n=26). A validation study was conducted including 6-, 8- and 11-year-old children (n=210). All subtests presented an increase in difficulty as the number of to-be-remembered items raised, and showed high Cronbach's α values. Regarding validity, all subtests had medium to high and significant correlations among them, and with two external measures of working memory (Picture Span and Word Order) and an executive function task (Tower of London); correlations with Block Design were low and non-significant. We conclude that the adapted AWMA can be considered a valid and reliable battery of working memory in Argentinean Spanish-speaking children.Fil: Injoque Ricle, Irene.
