The Inheritance of Reading Disability : Evidence from a Twin Study
No full textviii, 21 p.Reading disability is a major educational concern to students, parents, and educators. Because it may affect up to 10-15% of school-age children with average IQ and ample educational opportunity (Defries, Fulker, & LaBuda, 1987), research on the etiology of the disorder is clearly warranted. Results of the present study provide evidence for a genetic etiology of reading disability. Seventy-five identical twin pairs and fifty-nine fraternal twin pairs in which at least one member had evidence of reading problems in school were administered a battery of school achievement and psychometric tests. Scores from the Reading Recognition, Reading Comprehension, and Spelling subtests of the Peabody Individual Achievement Test were subjected to principal component analysis and used to create individual composite reading scores. The more severely affected pair member with evidence of reading problems at school was the proband, while his/her twin was designated the cotwin. It was hypothesized that the identical and fraternal cotwins' composite scores would regress differentially toward the mean of the unselected population to the extent that reading disability is heritable. Multiple regression analyses of the twin data (Defries & Fulker, 1985) provided evidence for a significant genetic etiology of reading disability. Approximately 50% of the reading deficit of probands may be due to heritable influences. Application of extended multiple regression models could give improved risk estimates, facilitate early diagnosis, and provide validity tests for suggested subtypes of reading disability.

Multivariate Parent-Offspring Analyses of Specific Cognitive Abilities:Nature, Nurture, and the Transition to Early Adolescence
No full textDuring the last few decades, family, twin, and adoption designs havebeen used to assess the genetic and environmental etiologies of specificcognitive abilities (SCA). The largest family study of SCA was the HawaiiFamily Study of Cognition, which included test data from 1,816 intactnuclear families. Measures of parent-offspring resemblance can only beconsidered via upper-bound estimates of heritability. Thus, family studiescan provide conclusive evidence for the familiarity of a trait, but not forits genetic etiology. In contrast, results obtained from twin studies canprovide estimates of heritability. This chapter discusses the results ofmultivariate genetic analyses of Colorado Adoption Project (CAP) parent-offspringdata at seven and twelve years of age, and compares them tothose obtained by Rice et al. (1989) when the CAP children were onlyfour years of age. The etiologies of individual differences for each of thefour measures — verbal, spatial, perceptual speed, and memory — andtheir covariation were assessed by fitting a parent-offspring multivariateconditional path model to CAP specific cognitive abilities data

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
