When the mental number line involves a delay: the writing of numbers by children of different arithmetical abilities

Our study focused on number transcoding in children. It investigated how 9-year-olds with and without arithmetical disabilities wrote Arabic digits after they had heard them as number words. Planning time before writing each digit was registered. Analyses revealed that the two groups differed not only in arithmetical abilities but also in verbal and reading abilities. Children with arithmetical disabilities were overall slower in planning Arabic digits than were control children with normal arithmetical abilities. In addition, they showed a number size effect for numbers smaller than 10, suggesting a semantically mediated route in number processing. Control children did not need more planning time for large numbers (e.g., 8) than for small numbers (e.g., 3), suggesting a direct nonsemantic route. For both two- and three-digit numbers, both groups of children showed a number size effect, although the effect was smaller each time for control children. The presence of the stronger number size effect for children with arithmetical disabilities was seen as a delay in the development of quick and direct transcoding. The relation between transcoding problems and arithmetical disabilities is discussed. A defect in the linking of numerical symbols to analog numerical representations is proposed as an explanation for the transcoding problems found in some children.     

Effectiveness of school-based prevention and intervention programs for children and adolescents with emotional disturbance: A meta-analysis

The present study evaluated the effectiveness of school-based prevention and intervention programs for children and adolescents at-risk for and with emotional disturbance. Published outcome studies (k = 29) from December, 1988, to March, 2006, including 1405 children and adolescents were reviewed. Each investigation was coded on several variables describing the child, parent, and teacher samples, as well as reported outcome results. The overall mean weighted effect size was 1.00 at post-test and 1.35 at follow-up. Mean weighted ESs were 0.42 for between-subjects design studies, 0.87 for within-subjects design studies, and 1.87 for single-subject design studies. Prevention programs yielded a mean weighted ES of 0.54 and intervention programs produced a mean weighted ES of 1.35. Findings for specific outcome foci are presented and implications are discussed.     

Person‐Group Value Congruence and Subjective Well‐Being in Students from Argentina,Bulgaria and Finland: The Role of Interpersonal Relationships

The present study examined the relations between personal values, value congruence, interpersonal relationships and subjective well‐being in psychology/education and business students from Argentina (N = 275), Bulgaria (N = 182) and Finland (N = 148). Regression analyses showed, first, that there were no direct relations between higher order value priorities and life satisfaction (LS), positive affect (PA) or negative affect (NA). Second, objective value‐congruence (VC)—the similarity between individual and group values—was positively related to LS and PA, and negatively related to NA. Most importantly, the effects of VC on LS, NA and PA were partially mediated by good interpersonal relationships. Our results show that interpersonal relationships are facilitated by sharing values similar to those of one's fellow students. More generally, personal values per se appear not to be associated with subjective well‐being, more important is how these values fit into the social context.

Dialogue Foundations: Dialogue Logic Revisited: Erik C. W. Krabbe

In an attempt to redeem the Lorenzen-type dialogues from their detractors, it is perhaps best first to provide a survey of the various benefits these dialogues have been supposed to yield. This will be done in Section I. It will not be possible, within the confines of this paper, to scrutinize them all, but in Section II we shall delve deeper into the capacity of this type of dialogue to yield a model for the immanent criticism of philosophical positions. Section III will extend the concept of a dialogue in such a way as to conform better with our intuitive conceptions of what a rational discussion of a position should contain. This will be followed up by a concept of 'winning a dialogue' that takes position midway between the old conception of 'winning one play' and that of the full-fledged presentation of a winning strategy (a proof). Concepts of 'rational discussion' are thus shown to be, plausibly, more fundamental than those of proof. In Section IV, I shall discuss the specific problems about dialogical foundations put forward by Wilfrid Hodges.

Policy evaluation: Design and utilization

In the 1960s when evaluation research came into fashion in the US, the assumption was that it would be used by public policymakers in an instrumental way for purposes of problem solving. This entailed a linear, knowledge-driven model for research utilization in which a direct relationship exists between knowing and doing (i.e., knowledge leads to action). The model combined the “rational” paradigm of organizational theory and the “scientific” paradigm of positivist philosophy of science into a consistent model of how evaluation research should be conducted and would be utilized. Both with respect to its normative and its empirical dimensions, original evaluation research model failed. Today evaluation research and its utilization are seen in quite a different perspective. However, though a parallel paradigm revolution or shift has taken place both with respect to the organization theory of evaluation research and its methodological basis, no new comprehensive and coherent evaluation research model has emerged to replace the original linear one. Erik Albaek is an associate professor of public administration at the University of Aarhus, Denmark. One of his main research areas is the utilization of social science in public policymaking.     

The gnosis of knowledge navigation on the Net

A set of activities developed to expose liberal arts undergraduates to global networking software and resources is detailed. Using a suite of Internet software tools and Macintosh computers, teams of students collaborated with faculty searching the World-Wide Web for on-line resources. Detailed student logs provide insights into the challenges of searching for Internet resources. Project shortcomings include difficulty in accessing information sites and poor organization of the final written reports. Ideas for improving the project in the future include allowing more time for the search process and replacing the written report with a WWW home page. The class project enhances the utilization of technology in the curriculum while equipping the students with computer skills to enhance their education.
