Children with autism and picture books: extending the reading experiences of autistic learners of primary age

Autistic learners master visual and spatial abilities; they use visual language to organise, understand and give meaning to the world. Although they might struggle with verbal skills, they have an associative way of thinking. Taking into consideration the characteristics of seven autistic pupils, the aim of this paper was to identify the potential of picture books in relation to autistic readers in order to explain why picture books can be supportive tools for improving verbal and social communication skills. The findings, based on a qualitative case study and a reader response framework, show that picture books help children with autism develop social and communication skills as well as foster imagination. Their written outcomes clearly showed children's need to tell stories.     

A new tool to classifying new technology-based firm prospects and expectations

This is an exploratory insight into the profile and prospects of growth and success attached to one category of firms, the so-called New Technology-Based Firms (NTBFs). Analysis of our empirically based data from 30 NTBFs leads us to the Market-Technology-Entrepreneurial (M-T-E) Matrix, whose eight three-dimensional quadrants serve to classify high-tech new ventures by performance. A factorial analysis coupled with a discriminate analysis are the statistical tools employed in obtaining the M-T-E Matrix and ascribing predictive capacity to it.     

Widely linear estimation for multisensor quaternion systems with mixed uncertainties in the observations

The optimal widely linear state estimation problem for quaternion systems with multiple sensors and mixed uncertainties in the observations is solved in a unified framework. For that, we devise a unified model to describe the mixed uncertainties of sensor delays, packet dropouts and uncertain observations by using three Bernoulli distributed quaternion random processes. The proposed model is valid for linear discrete-time quaternion stochastic systems measured by multiple sensors and it allows us to provide filtering, prediction and smoothing algorithms for estimating the quaternion state through a widely linear processing. Simulation results are employed to show the superior performance of such algorithms in comparison to standard widely linear methods when mixed uncertainties are present in the observations.     

Academics’ participation in quality assurance: does it reflect ownership?

Academics’ support for quality assurance (QA) depends on several factors, including their sense of ownership, which seems to be influenced by academics’ participation in QA’s implementation. This paper aims to understand whether this participation is indeed contributing to academics’ ownership of QA. Findings from a survey of Portuguese academics’ on their participation in study programmes accreditation suggests that this may not be the case. Academics present a partial withdrawal towards effective participation in study programmes’ accreditation, especially regarding external assessment. Furthermore, they do not seem willing to enhance this participation nor are they very critical about it. Since academics’ sense of ownership is essential for the successful implementation of QA, these results may represent a challenge for both institutions and QA agencies.     

Psychometric properties of child- and teacher-reported curl-up scores in children ages 10-12 years

The purpose of this study was to examine the psychometric properties of child- and teacher-reported curl-up (CU) scores in children ages 10-12 years in both a norm-referenced (NR) and criterion-referenced (CR) framework. Eighty-four children, 36 boys and 48 girls, performed the FITNESSGRAM (Cooper Institute for Aerobics Research, 1992) CU test on 2 days separated by 48-72 hr. Two video cameras were used to record students' CU performances. Two students performed the CU at the same time, with each child's performance recorded by one camera. The test was terminated when the child stopped due to fatigue or after two form errors occurred. Teacher-reported scores were the average of two independent ratings of each video performance, while child-reported scores came from data collected and recorded by the children. Single trial norm-referenced reliability was R = .75 for girls and R = .80 for boys for teacher-reported CU and R = .69 and R = .70 for child-reported CU for girls and boys, respectively. CR reliability was examined using P, proportion of students who consistently passed or failed the test across 2 days, and km, defined as reliability with chance removed. For teacher-reported scores, P = .89 and km = .78 for boys and P = .81 and km = .62 for girls. For child-reported scores, P = .86 and km = .72 for boys, while P = .79 and km = .58 for girls. For teacher-reported data, 39% of boys passed and 50% failed the test on both days, while for girls the percentages were 27% pass and 54% fail. For child-reported data, 64% of boys passed and 22% failed on both days, while 54% of girls passed and 25% failed. NR validity was examined by correlating teacher and child-reported scores. The resultant coefficient was r = .42 (95% CI = .11-.66) for boys and r = .67 (95% CI = .58-.74) for girls. Additionally, child-reported scores were significantly higher than teacher-reported scores. CR validity was examined with a contingency coefficient, and results indicated C = .55 with 44% false master errors for boys and C = .65 with 29% false master errors for girls. The findings of this study suggest that while NR reliability estimates were moderate for teacher-reported scores, single trial estimates suggest that child-reported CU should be viewed with caution. In regard to CR reliability, both teacher-reported and child-reported reliability were moderate. However, there were marked differences between teacher- and child-reported scores, with children reporting higher percentages of students passing and lower percentage of student failing the test when compared with scores reported by teachers. Validity was rather moderate when viewed in either a NR and CR framework. It is suggested that problems with child-reported scores may be due to the need for additional practice or simplification of the testing protocol.     

Specific reading disability: Follow-up studies

Twenty-four children with specific reading disability, originally studied and treated at the Bellevue Hospital Mental Hygiene Clinic between 1949 and 1951, were reexamined as young adults between 1961 and 1962 with the battery of tests given to them ten to 12 years before. Their specific perceptual problems and evidence of lack of clear- out cerebral dominance persists, although in less severe form. Those patients who as children had neurological signs in addition to the specific reading disability showed less improvement than those who had none.
