A Good Story: Children With Imaginary Companions Create Richer Narratives

In line with theories that children's pretend play reflects and extends their narrative skills, children with imaginary companions were predicted to have better narrative skills than children without imaginary companions. Forty-eight 5½-year-old children and their mothers participated in interviews about children's imaginary companions. Children also completed language and narrative assessments. Twenty-three of the children (48%) were deemed to have engaged in imaginary companion play. Children with and without imaginary companions were similar in their vocabulary skills, but children with imaginary companions told richer narratives about a storybook and a personal experience compared to children without imaginary companions. This finding supports theories of a connection between pretend play and storytelling by the end of early childhood.     

Rotational and linear head accelerations from taekwondo kicks and punches

The purpose was to compare rotational and linear head accelerations as a result of taekwondo kicks and punches. Taekwondo athletes executed five repetitions of the turning kick, spinning hook kick, hook punch, straight punch, and jab punch to a Hybrid III Crash Test Dummy head-neck complex. A tri-axial accelerometer and an angular rate sensor were mounted inside the Hybrid III head to measure resultant linear (RLA) and rotational accelerations. The Hybrid III was fixed to a height-adjustable frame and fitted with protective taekwondo headgear. Dummy head height was positioned to each participant’s standing height. Acceleration data were processed in accordance with SAE J211-1.There was no significant multivariate difference in RLA but the effect was not clear. Univariate follow-up analysis showed a significant difference in RLA but the effect was also not clear. There was no difference in rotational acceleration. The highest RLA and rotational acceleration were produced, in order, by the turning kick, hook kick, hook punch, straight punch, and jab. These data are clinically important as they provide a better understanding of the biomechanical injury measures and support for improved headgear testing methodology.     

Aerobic exercise training performed by parents reduces mice offspring adiposity

The present study aimed to determine the effects of physical training performed by parents on mice offspring adiposity. Male and female parents underwent an aerobic training protocol for 7 weeks. The trained and sedentary parents were allowed to mate and the resultant offspring divided in: S (Offspring from Sedentary Parents), T (Offspring from Trained Parents), ST (Offspring from Sedentary Father and Trained Mother) and TS (Offspring from Trained Father and Sedentary Mother). After weaning, offspring was euthanized, blood collected and samples of mesenteric and inguinal fat pads used to isolate adipocytes for morphologic and histological analyses. Lee index, mesenteric fat pad, sum of visceral fat and total fat weight of female T was reduced in comparison to the other groups (p < 0.05). Periepididymal and sum of visceral fat in male T group was also reduced when compared to the other groups (p < 0.05). The diameter of mesenteric and inguinal adipocytes of T group was smaller compared to all groups comparisons for both sexes (p < 0.05). In summary, exercise training performed by parents reduced visceral offspring adiposity, the diameter of subcutaneous adipocytes and improved metabolic parameters associated to metabolic syndrome.     

A model for the effective engagement of all stakeholders in engineering education and its pilot implementation

Methodologies for engineering learning and teaching (MELT) approach aims to enhance the attractiveness of education through science, technology, engineering and mathematics (STEM) among young people, while promoting awareness of future careers in these areas. To this end, students’ expectations are considered within university programmes, aiming to an increased engagement in STEM careers. To accomplish these goals, a new and integrated approach (MELT) is presented, involving the main stakeholders in both scientific education and society. An education framework is presented, providing guidelines for an improved collaborative approach to STEM education in the future. Results from the pilot implementation of MELT are presented, from a small-scale education parliament prototype. From these initial stage and results, it is seen that there is a need for a proper alignment of expectations from all involved stakeholders, concerning the engineering education towards society’s demands.     

Extending Previous cG×I Findings on 5‐HTTLPR's Moderation of Intervention Effects on Adolescent Substance Misuse Initiation

This study addresses replication in candidate gene × environment interaction (cG×E) research by investigating if the key findings from Brody, Beach, Philibert, Chen, and Murry (2009) can be detected using data (N = 1,809) from the PROSPER substance use preventive intervention delivery system. Parallel to Brody et al., this study tested the hypotheses that substance misuse initiation would increase faster from age 11 to age 14 and be higher at age 14 among: (a) 5‐HTTLPR short carrier adolescents versus long homozygotes, (b) control versus intervention adolescents, and (c) 5‐HTTLPR short carriers in the control condition versus all other participants. The hypotheses were generally supported and results were consistent with Brody et al.'s cG×I finding. Results are discussed in light of replication issues in cG×E research and implications for intervention.     

Remote Teaching with Digital Video: A Trans-national Experience

This paper analyses the psychological, technical, administrative, organisational, institutional and general pedagogical problems encountered during Phase 1 (the trial phase) of a trans-European distance-learning project. Using basic-rate ISDN videoconferencing for remote interactive tutorials, Phase 1 involved the University of Wales Swansea and HEC Liège (Belgium), and provided practice in business English for Belgian students and business French for UK students of French and Business. The difficulties which have arisen during the phase have been many and varied, and not all could have been easily predicted from a review of the research literature. Solutions to some of them are suggested.     

Testing collective memory: Representing the Soviet Union on multiple-choice questions

This article tests the assumption that state-mandated multiple-choice history exams are a cultural tool for disseminating an ‘official’ collective memory. Findings from a qualitative study of a collection of multiple-choice questions that relate to the history of the Soviet Union are presented. The 263 questions all come from New York State Regents exams that were administered between 1980–2010. Test questions were organized by decade, analysed for content, and then synthesized into historical narratives. These narratives were then analysed to see the extent to which they changed as the Soviet Union decayed, collapsed, and then broke up into new nation states. Particular attention was paid to the period that begins with the Cold War and ends with the present situation in post-Soviet Russia. The analysis shows that, despite great upheavals in the history of the Soviet Union, and changes in New York State standards and testing policies, the narrative that exists on these exam questions largely remains the same. This suggests that official narratives are slow to change. Further research should look at the extent to which test-taker knowledge and acceptance of official narratives affect performance on multiple-choice history items.     

'REDEFINITION OF IMAGE': THE IMPACT OF MASS-MEDIATED TERRORISM

The emergence of media-oriented terrorism led several scholarsof modern terrorism to reconceptualize the phenomenon of terrorwithin the framework of symbolic communication theory. However,the success of media-minded terrorists has been studied mainlyby measures of amount of coverage given to terrorist acts andnot by examining the impact of this coverage on public opinion.The present study sets out to examine the effects of media coverageof two terrorist events on the public's attitudes and perceptions.By means of an experimental design, the impact of press andtelevision reports of two terrorist incidents was studied. Thefindings highlight the ‘redefinition of image’ causedby exposure to media reports and relate media functions suchas status-conferral and agenda setting to the specific caseof mass-mediated terrorism.     

Disciplinary Text-Dependent Questions: Questioning for Learning in the Disciplines. The Challenge of Literacy in the Disciplines

The challenge of reading across disciplines is often not a matter of word recognition or general comprehension instruction; it is a matter of understanding how ideas are represented in the language and conventions of that discipline. In this article we describe a strategy for foregrounding the disciplines in the design and implementation of text-dependent questions in content area courses in order to accomplish a dual focus on content and discourse when using discipline-specific texts.
