Conclusion
Full text linkThis chapter presents some concluding remarks. In what has been an unprecedented time in the UK for family policy initiatives and developments, the new large-scale longitudinal survey of babies that was launched in the Millennium Cohort Study (MCS) of 18,819 babies has provided an interesting opportunity for analysis. This book has given people the chance to start to dip into the richness of this new survey, explore its potential, compare its findings with earlier generations and provide some benchmarks for the future with this new generation of children who have started out life in this era of new UK family policy. This chapter presents some final thoughts about policy questions such as babies under different family structures and parenting regimes; fathers' involvement in childcare; child poverty; working mothers; parental employment; babies'health and development, and social capital
Self-assessment of executive function and lateralization of brain pathology: What does the DEX-S profile show?
No full textCel pracyCelem badań własnych było 1). porównanie ogólnego wyniku oraz profilu DEX-S osób zdrowych i z patologią mózgu, w tym - uwzględnienie lateralizacji patologii mózgowej, oraz 2). określenie związków wyniku DEX-S z poziomem wybranych kompetencji poznawczych. Do badań zakwalifikowano 115 osób, w tym: bez patologii mózgowej (K; N=74), z uszkodzeniem lewej (LP; N=6), prawej (PP; N=12) i obydwu półkul (OP; N=23).MetodaZastosowano DEX-S, podtesty WAIS: Słownik, Cyfry wprost, wspak, test MoCa i skalę Afektu z kwestionariusza ProCog.WynikiWynik ogólny DEX-S nie różnicował grup, jednak najwyższe przeciętne wyniki uzyskały grupy PP i OP. Odnotowano różnice międzygrupowe w wynikach jedynie kilku itemów DEX-S. Osoby z patologią prawej i obu półkul raportowały istotnie wyższe poczucie trudności wykonawczych, głównie w zakresie uwagi, podatności na dystraktory, planowania, sekwencyjnego działania oraz rozwiązywania problemów. Z kolei grupa LP uzyskała najniższy wynik DEX-S. Grupa PP uzyskała niższe wyniki w zadaniach angażujących funkcje poznawcze w porównaniu do innych pacjentów. Wszystkie grupy kliniczne różniły się pod względem wyników w testach/zadaniach do oceny wybranych funkcji poznawczych od osób zdrowych. W każdej grupie odnotowano dodatnie korelacje pomiędzy wynikiem DEX-S a poczuciem niepokoju i brak związku z wiekiem oraz incydentalne z wynikami zadań poznawczych.WnioskiWyniki sugerują zależne od lateralizacji patologii mechanizmy poczucia deficytów wykonawczych. Wysokie poczucie deficytów wykonawczych u osób z patologią prawej półkuli może być zależne od sprawności pamięci odroczonej, i może odzwierciedlać adekwatną samoocenę swoich kompetencji. Niski wynik w DEX-S grupy z patologią lewej półkuli może wynikać z obniżonej, mimo braku afazji, sprawności językowej/semantycznej nie zaś z braku wglądu w ograniczenia wykonawcze.</jats:sec
Factor analysis of the self-report Dysexecutive (DEX-S) Questionnaire
No full textThe self-rating Dysexecutive Questionnaire (DEX-S) is a recently developed standardized self-report measure of behavioral difficulties associated with executive functioning such as impulsivity, inhibition, control, monitoring, and planning. Few studies have examined its construct validity, particularly for its potential wider use across a variety of clinical and nonclinical populations. This study examines the factor structure of the DEX-S questionnaire using a sample of nonclinical (N = 293) and clinical (N = 49) participants. A series of factor analyses were evaluated to determine the best factor solution for this scale. This was found to be a 4-factor solution with factors best described as inhibition, intention, social regulation, and abstract problem solving. The first 2 factors replicate factors from the 5-factor solutions found in previous studies that examined specific subpopulations. Although further research is needed to evaluate the factor structure within a range of subpopulations, this study supports the view that the DEX has the factor structure sufficient for its use in a wider context than only with neurological or head-injured patients. Overall, a 4-factor solution is recommended as the most stable and parsimonious solution in the wider context
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
