Children exposed to obscene phone calls: what they remember and tell

OBJECTIVE: This case study examined children's reports from an obscene phone call (i.e., a verbal sexual abuse). We investigated which type of information the children reported, the completeness and accuracy of the children's statements, and whether there were systematic patterns in terms of memory distortions and omissions. METHOD: The completeness and the accuracy of the children's statements were examined by matching 64 children's statements given during police interviews with a detailed documentation of each phone call, made by the perpetrator during the actual phone calls. RESULTS: All children remembered the phone call per se, but they were found to omit almost all of the sexual and sensitive information (perpetrator's questions and statements) and about 70% of the neutral information given by the perpetrator. However, the children were accurate in the information they did report. CONCLUSIONS: The fact that the children did remember more of the neutral information suggests that they actually remembered the sexual information as well, but that they chose not to report it. Results indicate that children who have been sexually abused may remember more than they report in an initial interview. One possible underlying reason is that children experience shame or embarrassment.     

Investigating the Validity of the Australian Early Development Index

This article aims to contribute to the ongoing evaluation of the Australian Early Development Index (AEDI) by investigating its construct and concurrent validity with a subsample of 642 children aged 4 to 5 years drawn from the Longitudinal Study of Australian Children (LSAC). Construct validity was examined by considering the theoretical consistency of the network of correlations between the AEDI subconstructs and the independently reported multimethod measures of early learning skills and development collected contemporaneously by the LSAC. Concurrent validity was examined by assessing the extent to which children who were “developmentally vulnerable” on the AEDI domains corresponded with the LSAC outcome indices classification of children as “developmentally at risk.” Moderate to large correlations were observed between each of the AEDI domains and subconstructs when compared to analogous teacher-rated LSAC measures, with lower levels of association observed for parent-rated LSAC measures. Concurrent validity was explored; however, with no criterion measure with which to assess the AEDI, findings are inconclusive prior to predictive validity assessment. Future waves of the LSAC will collect information on the children's abilities at school and developmental outcomes, enabling further interpretation of these concurrent and construct validity findings by triangulation and predictive validity analyses.     

Visualising Famagusta: interdisciplinary approaches to the study of the Orthodox Cathedral of Saint George of the Greeks in Famagusta,Cyprus

This paper explores a recent interdisciplinary project which brought together a visualization expert, an art historian, and an architectural historian, to study the ruins of Saint George of the Greeks Cathedral in Famagusta, eastern Cyprus, then create a virtual three-dimensional reconstruction of it. The motivation for this work, funded by Nanyang Technological University in Singapore, was to apply existing knowledge and expertise to a difficult, and very particular, heritage question on this Eastern Mediterranean Island. The creation of such a model could, it was felt, not only reiterate the academic value of thorough archival work married to state of the art technology, but also have very practical reverberations in terms of future heritage welfare and education via this ‘borderless’ domain.     

Complex adaptive information flow and search transfer analysis

Studying information flow between node clusters can be conceptualised as an important challenge for the knowledge management research and practice community. We are confronted with issues related to establishing links between nodes and/or clusters during the process of information flow and search transfer in large distributed networks. In the case of missing socio-technical links, social networks can be instrumental in supporting the communities of practice interested in sharing and transferring knowledge across informal links. A comprehensive review of methodology for detecting missing links is provided. The proportion of common neighbours was selected as best practice to elicit missing links from a large health insurance data set. Weights were based on geographical arrangements of providers and the dollar value of transactions. The core network was elicited based on statistical thresholds. Suspicious, possibly fraudulent, behaviour is highlighted based on social network measures of the core. Our findings are supported by a health insurance industry expert panel.     

Approaches to teaching in higher education: Validation of a Dutch version of the Approaches to Teaching Inventory

The Approaches to Teaching Inventory (ATI) is used to examine teachers’ teaching approaches in higher education. Analyses into the validity and reliability of the original English ATI yielded positive results. In this study, we examined the degree to which these positive results can also be found for the Dutch version that we developed. Data were gathered from 377 teachers at the University of Antwerp (Flanders, Belgium) and three Antwerp university colleges. Confirmatory factor analyses and principal factor analyses with oblique rotation support a model with sub-factors belonging to two main factors. Our research supports the reliability and validity of our current Dutch version of the ATI. Consequently, the instrument can be used in educational research or practice to obtain insights into the teaching approach of teachers. Further research into differences in the structure of the ATI when used in different cultures would be valuable.     

Hardness measurement of natural and hybrid turf soccer fields

Understanding the surface hardness of soccer fields is essential to evaluate the risk of injury and also its influence on the playing behavior of soccer players. In this context, newly developed hybrid turf systems have to be tested for their surface hardness with regard to the increased risk of injury on hard sports surfaces. The hardness of a soccer field can be quantitatively measured using an apparatus with a cylindrical weight that is dropped from a defined height. Since this procedure was first used for road construction, there are few studies investigating its use on sports grounds. This has led to inconsistencies in methodology and the absence of evaluation guidelines for classifying the hardness of soccer fields. This paper considers how turf systems (natural turf and hybrid turf) differ in their hardness and how this method can be used for different soccer turf systems. Natural turf systems, stitched turf systems, hybrid turf-bearing layer systems and woven mat systems were investigated. The assessment results from a comparative representation of hardness values of different soccer fields. By comparison, natural turf systems were found to be the softest, while woven mat systems were the hardest. Furthermore, the parameters that might affect the hardness were investigated. The influence of the measured soil parameters decreases with an increasing number of measurements per measuring point. Turf system-specific correlations make it possible to reduce the amount of measurement effort.
