A comparison between the WISC and WISC-R among educable mentally retarded students

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old EMR students, who were matched according to sex and race. The WISC-R yielded significantly lower VS, PS, and FS IQ scores than the WISC for this predominantly rural Georgia population. The FS IQ scores from the WISC-R averaged 7.5 points lower than the WISC FS IQs, with similar differences noted for VS and PS scores. There was no significant difference in FS IQs between the two age groups. Results suggest that many children classified as “Borderline” or slightly above by the WISC will be classified as “Mentally Deficient” by the WISC-R.     

Three-dimensional geometric moment bounding techniques

Important problems exist in the field of communications theory whose solution is in the form of an expectation of a function of a random variable. Often it is not computationally feasible to evaluate these moments exactly. This paper presents a geometric bounding technique that yields tight upper and lower bounds to generalized moments of a broad class of random variables. This technique produces excellent results for these communications theory problems.     

Parental cognitive impairment and child maltreatment in Canada

Objectives

The aim of this study was to determine the prevalence of parental cognitive impairment in cases opened for child maltreatment investigation in Canada, and to examine the relationship between parental cognitive impairment and maltreatment investigation outcomes including substantiation, case disposition and court application.

Methods

The method was secondary analysis of the Canadian Incidence Study of Child Abuse and Neglect (CIS-2003) core-data, which is derived from a multi-stage stratified cluster sample of 11,562 child maltreatment investigations.

Results

Parental cognitive impairment was noted in 10.1% of sampled cases that were opened for child maltreatment investigation in 2003, and in 27.3% of sampled cases that resulted in child welfare court application. Neglect was the most common cause of concern. With child and case characteristics held constant, parental cognitive impairment predicted investigation outcomes. The data further suggest that the relationship between parental cognitive impairment and investigation outcomes was partially mediated by perceived parent non-cooperation, mental health issues and low social support.

Conclusions

The number of children who are living with a parent with cognitive impairment and who are referred for protective services is thought to be increasing. Building systems capacity to support parents with cognitive impairment and promote child wellbeing is therefore essential to containing the human and economic costs of maltreatment and out-of-home care.

Practice implications

A broad-spectrum approach is needed to support parents with cognitive impairment and their children. Equipping services with the knowledge, skills, and mandate they need to deliver evidence-based parent training is vital. However, strategies are also needed to tackle discrimination, alleviate family poverty, strengthen the social ties of parents with cognitive impairment and in turn, improve the life chances of their children.     

Factors Affecting the Balance Between Teaching and Research in the Universities of the Twenty‐First Century

The author suggests that the current mode of knowledge production at the leading edges of advanced studies in the sciences, the social sciences, and the humanities is changing dramatically. This development, that is being driven as much by the internal dynamics of knowledge production as by government policy and by the demand for competitiveness, has profound implications for the balance of teaching and research in universities. A traditional, university‐based mode of knowledge production, characterized by a linear model, that the author calls Mode 1, is being complemented and to some extent supplanted by a new type of knowledge production called Mode 2 that is characterized by knowledge produced in the context of application, transdisciplinarity, heterogeneity and organizational diversity, enhanced social accountability, and broadly based systems of quality control. Mode 2 knowledge production questions the validity of the linear model of knowledge production characteristic of Mode 1. Mode 2 requires the universities, particularly in regard to research, to come to grips with a new pattern for the social distribution of knowledge production, especially the fact that they are no longer either the sole or even the primary institutions on the cognitive landscape.
