Assessing the accuracy of the WISC-IV seven-subtest short form and the child and adolescent intellectual disability screening questionnaire in identifying intellectual disability in children

Little research has been conducted into the accuracy of abbreviated assessments in identifying children and young people with an intellectual disability (ID). The present study compared two such methods in a clinical population of individuals with (n = 106) and without (n = 170) ID: a 7-subtest short form of the Wechsler Adult Intelligence Scales for Children—fourth edition (WISC-IV) proposed by Crawford and colleagues and the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q). Both the CAIDS-Q and the WISC-IV short form had high and comparable levels of predicting group classification (88% and 91% correct classification, respectively). Both methods would appear to offer clinicians and researchers an efficient and accurate means of identifying those who are likely to have ID. The WISC-IV short form was slightly more accurate, but the CAIDS-Q may offer the advantages of being shorter to administer and having no requirement for the user to have a particular qualification or training.     

Working Memory In Individuals With Fragile X Syndrome

The present research tests the hypothesis that fragile X syndrome (FXS) is associated with a deficit in working memory (WM) and the deficit is more pronounced the higher the control requirements of the task. To this purpose, 15 boys with FXS and 15 typically developing children, matched for mental age, assessed with Logical Operation Test, were tested with batteries of 4 verbal and 4 visuospatial WM tasks requiring different levels of control. Children with FXS showed a performance equal to controls, in WM tasks requiring low and medium-low control but significant impairment in correspondence with greater control requirements. Results show that boys with FXS present a WM deficit only when high control is required by the task, supporting the hypothesis that control can be a critical variable distinguishing WM functions and explaining intellectual differences. On the contrary the hypothesis that the FXS is associated with a visuospatial deficit was not supported.     

The ethics of belief: doxastic self-control and intellectual virtue

Most of the literature on doxastic voluntarism has concentrated on the question of the voluntariness of belief and the issue of how our actual or possible control of our beliefs bears on our justification for holding them and on how, in the light of this control, our intellectual character should be assessed. This paper largely concerns a related question on which less philosophical work has been done: the voluntariness of the grounding of belief and the bearing of various views about this matter on justification, knowledge, and intellectual virtue. In part, my concern is the nature and extent of our voluntary control over our responses to reasons for believing—or over what we take to be such reasons. This paper provides a partial account of such control and, on the basis of the account, will clarify the criteria for appraising intellectual virtue.     

Longitudinal Changes in Intellectual Development in Children with Fragile X Syndrome

Structural equation modeling (SEM) was used to examine the development of intellectual functioning in 145 school-age pairs of siblings. Each pair included one child with Fragile X syndrome (FXS) and one unaffected sibling. All pairs of children were evaluated on the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) at time 1 and 80 pairs of children received a second evaluation at time 2 approximately 4 years later. Compared to their unaffected siblings, children with FXS obtained significantly lower percentage correct scores on all subtests of the WISC at both time points. During the time between the first and second assessments, the annual rate of intellectual development was approximately 2.2 times faster in the unaffected children compared to the children with FXS. Levels of the fragile X mental retardation protein (FMRP) were highly associated with intellectual ability scores of the children with FXS at both time points (r=0.55 and 0.64 respectively). However, when gender, age, and the time between assessments were included as covariates in the structural equation model, FMRP accounted for only 5% of the variance in intellectual ability scores at time 1 and 13% of the variance at time 2. The results of this study suggest that slower learning contributes to the low and declining standardized IQ scores observed in children with FXS.     

U.S. Patent Policy: Crafting a 21st Century National Blueprint for Global Competitiveness

The paper begins with an overview of the legal, institutional, and public policy bases of the U.S. patent granting system and subsequently examines major deficiencies acknowledged in the existing U.S. patent system. The paper then catalogs the essence of four patent reform proposals of the Federal Trade Commission, the National Research Council, and academic economists (Jaffe/Lerner and Maskus), all of which focus on ameliorating alleged major weaknesses in the U.S. patent system. The paper concludes with an analysis of the above cited patent reform proposals, arguing for a proposed set of workable policy recommendations (reflecting recent changes in public policy) focused on patent cost controls, patent quality, patent uncertainty, and patent reform legislation, all designed to contribute to a globally competitive 21st century patent policy for the U.S. economy.

Plagiarism: Words and Ideas

Plagiarism is a crime against academy. It deceives readers, hurts plagiarized authors, and gets the plagiarist undeserved benefits. However, even though these arguments do show that copying other people's intellectual contribution is wrong, they do not apply to the copying of words. Copying a few sentences that contain no original idea (e.g. in the introduction) is of marginal importance compared to stealing the ideas of others. The two must be clearly distinguished, and the 'plagiarism' label should not be used for deeds which are very different in nature and importance.     

Reliability as a virtue

This paper explores what constitutes reliability in persons, particularly intellectual reliability. It considers global reliability, the overall reliability of persons, encompassing both the theoretical and practical realms; sectorial reliability, that of a person in a subject-matter (or behavioral) domain; and focal reliability, that of a particular element, such as a belief. The paper compares reliability with predictability of the kind most akin to it and distinguishes reliability as an intellectual virtue from reliability as an intellectual power. The paper also connects reliability with insight, reasoning, knowledge, and trust. It is argued that insofar as reliability is an intellectual virtue, it must meet both external standards of correctitude and internal standards of justification.

REPLY TO JULIA DRIVER,TIMM TRIPLETT,AND KATHLEEN WALLACE

Abstract: Julia Driver, Timm Triplett, and Kathleen Wallace challenge my account of moral arrogance, and Triplett and Wallace challenge its application to the problem of abortion. I try to show here that Driver's attempt to defend consequentialism from my charge that it promotes moral arrogance is successful only if consequentialism explicitly gives up what has been considered one of its major virtues. I acknowledge that Triplett has uncovered some unclarity in my claim that the moral acceptability of abortion is an unresolvable moral issue. I also acknowledge that Wallace has uncovered some unclarity in my account of moral arrogance. After clarifying that account, I try to meet her challenge to defend my claim that it is not morally arrogant for a state to place some restrictions on abortions.     

People with intellectual disability who are ageing: Perceived needs assessment

Background/Objective: Ageing and progressive increase in life expectancy in people with intellectual disability present significant challenges. The present study is to examine the needs that arise in the aging process of this population. To detect these needs is fundamental to ensure personal wellbeing; almost no psychometrically sound instruments have been developed. Method: A structured interview was developed and evaluated by a panel of 20 experts to obtain evidence of content validity. The interview was then applied to 1,173 people with intellectual disability. The ages ranged from 35 to 80 (M = 52.27; SD = 7.5). Results: The interview consisted of 93 items evaluating four areas: perceived needs, personal problems, future perspectives, and solutions required. The results demonstrated the proximity and relationship of the various needs evaluated. In addition it was observed that those with intellectual disability who were older, male and users of residential services tended to indicate more needs, problems, and required more solutions. Conclusions: The instrument has adequate evidence of validity, allowing the evaluation of specific needs of people with intellectual disability. The results advocate the design of transversal intervention policies in order to effectively meet the needs and requirements of this population.
