Gross motor abilities and interventions in girls and women with Rett syndrome: A literature review ; Longitudinal video analysis of gross motor abilities of girls and women with Rett syndrome
Get PDFObjective: To explore research relevant to an understanding of gross motor abilities and highlight possible directions for gross motor intervention in girls and women with Rett syndrome. A secondary objective was to describe mouse model research which has the potential to add to an understanding of gross motor abilities in this population. Methods: Electronic searches of five databases, manual searches of an external resource library and manual searches of reference lists were undertaken. The key words imputed during these searches included; mobility, Rett syndrome, functioning, mouse model, therapy and intervention. Search terms were truncated, exploded and adjusted to achieve optimum results. A narrative review was possible. Results: The searches of the literature yielded research which will be discussed under the headings; phenotype-genotype correlations, gross motor functioning, therapy interventions, involving both gross motor interventions in girls and women with Rett syndrome and mouse model research. The research found that most girls/women with Rett syndrome can sit independently, approximately half can walk and many have difficulties with transitional movements. More complex gross motor skills, such as transitions, walking on a slope and stepping over an obstacle, have been highlighted as especially difficult for this population. Video analysis is an emerging methodology in this area and has the potential to ·provide better observational data, to measure change, investigate gross motor abilities and evaluate the effectiveness of gross motor interventions. Mouse model research has investigated environmental enrichment as a treatment paradigm resulting in amelioration of gross motor deterioration. Similarly, increasing the expression of BDNF in mice with MeCP2 mutants has resulted in reduced locomotor deficit. Conclusion: Further longitudinal and cross-sectional studies with rigorous design and larger sample sizes are required in order to guide therapeutic gross motor intervention in girls and women with Rett syndrome. Purpose: Rett syndrome is a rare neurological disorder often associated with a mutation in the MECP 2 gene. It results in severe physical and intellectual disability with a gradual decrease in acquired gross motor abilities. This study explored changes in gross motor abilities over three years in girls/women with Rett syndrome, recruited from a population-based data base. The relationships between these changes and age and genotype were investigated. Method: Families participating in the Australian Rett Syndrome Database were invited to participate in a video study. Ninety-nine families provided a video in 2004 and 70 of these cases submitted a second video in 2007. Gross motor data for the two time points were scored through the use of an assessment tool based on the Gross Motor Function Measure. Results: The level of general gross motor skills decreased in 58 (82.9%) and increased in 12 (17.1 %) cases (mean decrease in z-score 0.50 ± 0.59). The level of complex gross motor skills decreased in 67 (95.7%) and increased in 3 (4.2%) cases (mean decrease in z-score 1.58 ± 1.11). General motor skills declined for cases in each of the four age-groups. Compared to the girls who were younger than 8 years, the decrease in complex motor skills was greater for girls aged 13:S19 years (P=0.021) and women \u3e19 years (P=0.071). Conclusion: Over a 3-year period, there was a small amount of deterioration in general gross motor skills for girls of all ages and a larger deterioration in complex gross motor skills during the teenage years. This detailed understanding of the characteristics of declining gross motor skills in Rett syndrome could contribute to the development of strategies to ameliorate these trends
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
