On referee bias, crowd size, and home advantage in the English soccer Premiership

In a recent paper in this journal, Boyko and colleagues (2007) identified differences in attendance and referee bias as factors influencing home advantage at soccer matches in the English Premiership. A replication of their study using more recent data found no evidence to sustain either of their claims.     

Bowling ball dynamics revealed by miniature wireless MEMS inertial measurement unit

This paper presents a novel sensor technology to deduce the dynamics of a bowling ball. The sensor, a miniature wireless inertial measurement unit (IMU), incorporates MEMS accelerometers and angular rate gyros, a microcontroller, a low power RF transceiver, and a rechargeable battery. When embedded in a bowling ball, the IMU transmits the acceleration and angular velocity data that define the dynamics of the ball starting with the bowler’s delivery and its motion in the lane. Example results from professional bowlers illustrate how this technology can be used to assess bowler skill and ball performance. For instance, the IMU accurately measures the spin dynamics of the ball which are crucial to develop the ball “hook.” An analysis of ball dynamics in the lane is distilled to a measurable “hook potential” metric for further assessing bowler skill. Finally, the sensor presented herein is believed to be the world’s smallest, wireless IMU. This highly miniaturized and wireless design will enable parallel training systems for many sports, including basketball, baseball, crew, cricket, golf, fly fishing, soccer, softball, tennis, rowing, among others.     

The Effects of a Group Contingency Strategy on Behaviorally Disordered Students in Physical Education

Abstract

An A-B-A-B time-series design was used to determine the effectiveness of a group contingency strategy in modifying on-task behavior of behaviorally disordered students in a physical education setting. A younger group (n = 12) with a mean age of 7.8 years, and an older group (n = 11) with a mean age of 11.2 years, participated in a study in which activity reinforcement for each group was contingent upon correct observation of the rules established for class. The group contingency strategy was significantly effective in increasing the percentage of on-task behavior of both groups of students. In addition, there was no significant difference in the response to treatment between younger and older students, and there were no individuals within either group who did not respond favorably to treatment.     

Mothers’ Implicit and Explicit Attitudes and Attributions in Relation to Self-Reported Parenting Behavior

Objective. Parenting behavior is presumed to be related to the thoughts about child behavior that parents report in a controlled and explicit manner and to more implicit parent cognitions that occur outside of conscious awareness and are less accessible to verbal report. Design. We examined mothers’ attitudes toward their children as correlates of self-reported parenting behavior. We used a combination of a self-report questionnaire and a reaction-time method (the Implicit Association Test) to assess explicit and implicit attitudes, respectively. We also assessed mothers’ implicit and explicit attributions for child misbehavior in relation to parenting, using a questionnaire measure of attributions completed under high-cognitive load (implicit attributions) or under low-cognitive load (explicit attributions). Mothers of 124, 6- to 10-year-olds (52% male) participated. Results. Attitudes assessed by self-report questionnaire and the Implicit Association Test were uniquely associated with negative parenting. The cognitive load manipulation moderated associations between attributions and parenting, such that child-blaming attributions were inversely associated with positive parenting only under conditions of high-cognitive load. Conclusions. Compared to traditional self-report questionnaires, methods such as the Implicit Association Test or cognitive load manipulations may more effectively assess implicit parent cognitions.     

The differential effects of prior knowledge on learning: A study of two consecutive courses in earth sciences

We studied the occurrence and nature of learningin a university first year Introduction toGeomorphology course, and its relations with priorknowledge taught in a prerequisite course, and withthe prior knowledge in the to be learned subjects. Tendimensions of knowledge were tapped before and afterthe course by conventional and cognitive structuremeasures that were derived by the concept mappingmethodology. The fine-grain analysis of learningoutcomes yielded the following results: (a) studentsacquired only a small portion of the content in thecourse Introduction to Geomorphology, (b) the priorgeological and geomorphological knowledge did notaffect the learning of the new geomorphologicalcontents, (c) the minor effects appeared within ratherthan across knowledge dimensions, and they affectedmainly the learning of smaller knowledge units, and(d) concept definition cannot be considereda valid probe of knowledge. The differential effects of prior knowledge question thecentral, global and undifferentiated role that schematheories ascribe to prior knowledge in futurelearning. They call for greater reference to theexposed dimensions of knowledge by suggestingadditional factors to be considered in the sequencingof courses, as well as to the acquisition of complexknowledge with partial meaning of the basic knowledgeunits, and the use of new cognitive structure probesof knowledge.     

Is There a Need for Transcendental Arguments in Discourse Ethics?

In this essay, James Scott Johnston examines Jürgen Habermas's transcendental justification of his discourse theory of morality. According to Johnston, the application of Habermas's theory to educational issues often assumes that this justification is a cogent one. However, if the theory is to provide reasoned and appropriate guidance for educators, the justification of discourse ethics requires closer examination. Johnston argues that Habermas's so‐called “weak” transcendental approach is in fact unsustainable because it fails to reconcile two conflicting schools of philosophical thought: Kant's transcendental idealism and George Herbert Mead's social pragmatism. Johnston concludes that a more plausible justification of the discourse ethical project can be achieved by rejecting Habermas's Kantianism and appealing solely to Mead's social pragmatic conception of rationality.     

Familiar Object Salience Affects Novel Word Learning

Children use the presence of familiar objects with known names to identify the correct referents of novel words. In natural environments, objects vary widely in salience. The presence of familiar objects may sometimes hinder rather than help word learning. To test this hypothesis, 3-year-olds (N = 36) were shown novel objects paired with familiar objects that varied in their visual salience. When the novel objects were labeled, children were slower and less accurate at fixating them in the presence of highly salient familiar objects than in the presence of less salient familiar objects. They were also less successful in retaining these word-referent pairings. While familiar objects may facilitate novel word learning in ambiguous situations, the properties of familiar objects matter.     

‘Sitting alone in the staffroom contemplating my future’: communities of practice,legitimate peripheral participation and student teachers’ experiences of problematic school placements as guests

A recent Review of Teacher Education in Scotland reports that 23% of respondents (n = 2381) encountered variable or very poor school placement experiences. This paper uses Lave and Wenger’s ideas concerning Communities of Practice (1998) and Legitimate Peripheral Participation (1991) as analytical tools with which to understand the nature and impact of student teachers’ problematic experiences of school placement. A total of 14 Professional Graduate Diploma in Education students on a one-year Secondary English course were followed through the practice elements of their Initial Teacher Education programme and data were constructed from learning logs and semi-structured interviews. Analysis provided a nuanced account of the student teachers’ difficulties in attaining member status as Legitimate Peripheral Participants in communities of practising teachers, with the concepts ‘joint enterprise’, ‘mutual engagement’ and ‘shared repertoire’ being found to be useful in explaining these difficulties. Limitations in the theoretical framework were also discovered and these are highlighted and developed in the paper.     

Professional Issues: Questioning the Use of Alcoholics Anonymous With College Students: Is an Old Concept the Only Alternative for a New Generation?

The recommended treatment for alcoholism in the past typically has been participation in Alcoholics Anonymous (AA). However, the use of AA on college campuses has not been proven effective. With a new generation comes the opportunity to rethink this approach to the problem of alcohol abuse on campuses and to incorporate new methods in counseling practice with young adults.
