Report of Committee on Criteria for Evaluation of Articles Submitted for Publication in the Research Quarterly April 1950

The aim of this study was to determine what visual information expert soccer players encode when they are asked to make a decision. We used a repetition-priming paradigm to test the hypothesis that experts encode a soccer pattern's structure independently of the players' physical characteristics (i.e., posture and morphology). The participants were given either realistic (digital photos) or abstract (three-dimensional schematic representations) soccer game patterns. The results showed that the experts benefited from priming effects regardless of how abstract the stimuli were. This suggests that an abstract representation of a realistic pattern (i.e., one that does not include visual information related to the players' physical characteristics) is sufficient to activate experts' specific knowledge during decision making. These results seem to show that expert soccer players encode and store abstract representations of visual patterns in memory.     

Modelling training response in elite female gymnasts and optimal strategies of overload training and taper

Abstract

The aim of the study is the modelling of training responses with a variable dose-response model in a sport discipline that requires highly complex coordination. We propose a method to optimise the training programme plan using the potential maximal performance gain associated with overload and tapering periods. Data from five female elite gymnasts were collected over a 3-month training period. The relationship between training amounts and performance was then assessed with a non-linear model. The optimal magnitude of training load reduction and its duration were investigated with and without an overload period using simulation procedures based on individual responses to training. The correlation between actual and modelled performances was significant (R ² = 0.81 ± 0.02, P < 0.01). The standard error was 2.7%. Simulations revealed that taper preceded by an overload period allows a higher performance to be achieved compared to an absence of overload period (106.3 ± 0.3% vs. 105.1 ± 0.3%). With respect to the pre-taper load, the model predicts that optimal load reductions during taper were 48.4 ± 0.7% and 42.5 ± 1.0% for overloading and non-overloading strategies, respectively. Moreover, optimal durations of the taper period were 34 ± 0.5 days and 22 ± 0.5 days for overloading and non-overloading strategies, respectively. In conclusion, the study showed that the variable dose-response model describes precisely the training response in gymnasts.

THINKING ABOUT THE NATURE AND ROLE OF AUTHORITY IN DEMOCRATIC EDUCATION WITH ROUSSEAU'S EMILE

Educational authority is an issue in contemporary democracies. Surprisingly, little attention has been given to the problem of authority in Jean‐Jacques Rousseau's Emile and his work has not been addressed in the contemporary debate on the issue of authority in democratic education. Olivier Michaud's goals are, first, to address both of these oversights by offering an original reading of the problem of authority in Emile and then to rehabilitate the notion of “educational authority” for democratic educators today. Contrary to progressive readings of Emile, he argues, Rousseau's position on this issue is not reducible to “education against authority.” What appears at first glance to be an education against authority is, in a deeper sense, an education toward and even within authority. Michaud contends that we have to embrace these complexities and contradictions that inform Rousseau's work in order to gain insights into the place and role of authority in democratic education. Michaud sheds light on Rousseau's stance on authority through a close study of specific topics addressed in Emile, including negative education, opinion, one's relation to God, friendship and loving relationships, and, finally, the relation Rousseau established with his reader.     

Attention-Deficit/Hyperactivity Disorder: Underlying Deficits in Achievement Motivation

This South African study aims at contributing to the debate regarding the processes underlying the core deficits of Attention-Deficit/Hyperactivity Disorder (ADHD) by investigating the motivational factors underlying the symptoms of ADHD. It investigates the difference between adolescents with ADHD (combined type) and adolescents without ADHD regarding their achievement motivation. The results add to previous knowledge regarding the motivational deficits demonstrated by ADHD children and provide a valuable insight into their achievement motivational patterns, especially regarding negative fear of failure and the motive to achieve. Recommendations are suggested regarding educational and therapeutic strategies to improve the ADHD child's motivation at home and at school.

Microarray of non-connected gold pads used as high density electric traps for parallelized pairing and fusion of cells

Cell fusion consists of inducing the formation of a hybridoma cell containing the genetic properties of the progenitor cells. Such an operation is usually performed chemically or electrically. The latter method, named electrofusion, is considered as having a strong potential, due to its efficiency and non-toxicity, but deserves further investigations prior to being applicable for key applications like antibody production and cancer immunotherapy. Indeed, to envision such applications, a high amount of hybrid cells is needed. In this context, we present in this paper a device for massive cell pairing and electrofusion, using a microarray of non-connected conductive pads. The electrofusion chamber––or channel––exposes cells to an inhomogeneous electric field, caused by the pads array, enabling the trapping and pairing of cells with dielectrophoresis (DEP) forces prior to electrofusion. Compared to a mechanical trapping, such electric trapping is fully reversible (on/off handling). The DEP force is contactless and thus eases the release of the produced hybridoma. Moreover, the absence of wire connections on the pads permits the high density trapping and electrofusion of cells. In this paper, the electric field mapping, the effect of metallic pads thickness, and the transmembrane potential of cells are studied based on a numerical model to optimize the device. Electric calculations and experiments were conducted to evaluate the trapping force. The structure was finally validated for cell pairing and electrofusion of arrays of cells. We believe that our approach of fully electric trapping with a simple structure is a promising method for massive production of electrofused hybridoma.     

Higher education students in contemporary France

The number of students entering higher education started to increase significantly in the mid-1960s. This sharp growth has gone together with diversification in the social background of those attending, creation of new tracks (mainly in technology) and, more recently, a number of pedagogical innovations. Consequently, higher education students in the 1990s have little in common with those described by Pierre Bourdieu and Jean-Claude Passeron in Les héritiers, published in 1964: they are not just young bourgeois whose university career confirms ex-post the social position of his or her family. The relative democratization of access to higher education has allowed young people from other social classes to continue their studies after the baccalauréat. However, this democratization has also created new problems for higher education institutions. They must make financial, organizational and pedagogical adaptation to mass schooling. Higher education students also confront new problems in adapting to such demands of university work as autonomy and initiative. Students' living conditions have also changed: while remaining economically dependent on their parents, they enjoy, especially in the provinces, considerable freedom in the running of their personal lives.     

Item analysis of the Wechsler Intelligence Scale for Children-Revised

Indices of item diffculty and item discrimination were analyzed for the items comprising the Wechsler Intelligence Scale for Children - Revised as obtained from a group of 142 subjects with Full Scale IQs below 96. Item validities were estimated by computing the biserial correlation between dichotomized item responses and the total weight score. Kendall's tau was computed for each item. The item difficulties for each subtest except Information and Vocabulary are roughly in the same rank order as those obtained by the stadardization group. Evidence from the study indicates that the increase in the number of items on the WISC-R helped to increase its internal Validity. Analysis of the data ragarding the internal consistency of the test indicates that the majority of the items operate as significant discriminators. Changes in the order of that administration and /or revision of the record form would not seem warranted on the basis of the present study.
