Number-word sequence skill and arithmetic performance

In two studies, the role of the number‐word sequence skill for arithmetic performance was investigated. In the first, children between 4 and 8 years of age were asked to count forward and backward on the number‐word sequence and to solve arithmetic problems followed by post‐solution interviews about solution procedures. The results demonstrated that the number‐word sequence skill predicted both number of problems solved and strategy to solve the problems. In Study 2 it was found that solving doubles (e.g., 2 + 2 = ?) problems served as a link between the number‐word sequence skill and the number of arithmetic problems solved. The findings suggest that counting on the number‐word sequence may be an early solution procedure and that, with increasing counting skill, the child may detect regularities in the number‐word sequence that can be used to form new and more accurate strategies for solving arithmetic problems.     

Salespeople as knowledge brokers: a review and critique of the challenger sales model

Over the last several years, there has been increasing interest in a new sales training approach – referred to as the Challenger Sales model – to engage customers. This approach, focusing on purposefully generating tension with customers to spark new ways of thinking, has gained traction among leading sales organizations. Although generating tension with customers has received a great deal of interest, researchers have yet to complete a systematic, in-depth examination of the Challenger model. The purpose of this article is to provide a much needed comprehensive review and critique of the approach. By conducting both an empirical and conceptual review of the framework, we offer insight into its novelty, merits and weaknesses.     

潜变量交互效应模型标准化估计中的检验问题

讨论了潜变量交互效应模型是否能直接用统计软件输出的原始估计的t值对模型的标准化估计进行检验的问题,详细介绍了标准化估计的t值计算及其难点,用Bootstrap方法算出标准化估计的标准误和相应的t值（记为t_bs）,并将其与原始估计的t值比较.结果发现,当原始估计t值超过3时,无论用t值还是用t_ bs检验,结果都是显著,即可以使用t值进行检验.而当t值不超过3时,与t_bs很接近,也可以用t值检验,但t值在临界值附近（例如1.5 ～2.5）时,最好还是使用Bootstrap法计算t_bs进行检验.     

Relationship between field dependence-independence and the g factor: What can problem-solving strategies tell us?

IntroductionField dependence-independence (FDI) has been the focus of a great deal of research. However, it is generally studied in relation to either personality or the g factor, with far fewer studies of the interconnections between FDI, the g factor and problem-solving strategies.ObjectiveOur first aim was to study the relationship between FDI and the g factor. Our second was to explain this relationship by analysing problem-solving strategies.MethodOne hundred and seventy 14-year-old performed three tests: the GEFT, the D-70, and a second, prototype g-factor test that enabled us to identify which strategies they used.ResultsResults confirmed the classic link between FDI and the g factor, and attributed this link to greater use of the most efficient strategies.     

A Solution-Based Approach to Couple Therapy

Abstract

Couples often present for counseling as a last resort. As relationships in crisis may not last it is important that treatment be time-effective. Solution-based therapies have been described as brief and time-effective and applied effectively to working with couples. This article presents a case example demonstrating the application of a solution-based approach to therapy with a married African-American couple entering therapy to resolve their relationship difficulties that lead to the initiation of divorce proceedings. The processes of reducing blame and conflict, creating hope and solution building utilizing solution-based interventions are discussed, as well as the treatment outcomes.     

Étude des stratégies d’adultes présentant un retard mental dans la résolution de la Twenty Questions Task

A Twenty Questions problem solving Task was given to 30 mentally retarded adults, 30 mentally nonretarded adults matched on chronological age, and 12 mentally nonretarded children matched on cognitive efficiency. Four strategies were identified on the basis of a subject-by-subject analysis. Results showed group differences of frequency in the use of the strategies. Moreover, results indicated that the more frequent strategy used by the mentally retarded adults is the one which consists in identifying the categories without using them to efficiently reduce the problem space. The interpretation of the results as reflecting a conceptual deficit or a chronicle cognitive sub-functioning of the mentally retarded adults depicted in the literature is discussed.     

医疗纠纷的解决机制

近年来,医疗纠纷呈上升趋势,不仅是医疗界和学术界关注的焦点和热点问题,而且已成为整个社会和政府极为关注并亟待解决的课题。在现有的法院诉讼、协商解决、行政调解等医疗纠纷解决机制下,应尽快建立医事仲裁制度,为解决医疗纠纷开辟新的途径。     

How do children deal with socio-moral conflicts? Self-conscious emotions and conflict resolution in the narratives of institutionalized and noninstitutionalized children

Introduction

Self-conscious emotions play an important role in children's psychosocial functioning.

Several programming models with unascertained parameters and their applications

Several programming models are introduced with the consideration of available unascertained information. In this case, the so‐called unascertained information is some numerical values whose ranges are known but their exact values are not. These models resolve several vital weaknesses of the traditional programming methods to a certain degree. Our study includes considerations of linear and non‐linear programming models with grey parameters, grey 0–1 programming, and satisfactory and quasi‐optimal solutions of grey linear programmings. Finally, some practical applications are given in order to test the applicability of our theory. Copyright © 1999 John Wiley & Sons, Ltd.     

Les erreurs commises lors de la résolution du problème source favorisent-elles le transfert analogique ? Un réexamen de la recherche de Gick et McGarry (1992)

Gick and McGarry (1992) show that inducing source problem difficulty by reducing the salience of its structural elements improves analogical transfer. According to them, this result is explained by similarities between mistakes made when solving the difficult source and target mistakes. In this study, we replicate Gick and McGarry study in order to do an analysis, not made by the authors, in the aim of testing the role of mistakes in analogical transfer. Our results replicate the effects Gick and McGarry observed, but show that theses effects are not explained by mistakes made on the source problem.
