Effects of Frame Repetition Through Cues in the Online Environment

Research has shown that message frames can shape a reader’s subsequent judgments on political issues. In the online news environment, additional cues outside the story may be present that can affect the power of the frame. This online experiment investigates the role of repetitive cues in the framing processes using news editorials and their accompanying recommended headlines that repeat the editorial’s frame. Results suggest that regarding issue-related attitudes and emotions, consistent frame repetition reinforced the effects of the original article when the frame’s relevance to the readers was high but undermined the article’s impact when the relevance was low. Implications for framing studies and online news consumption are discussed.     

Assessing Model Fit: Caveats and Recommendations for Confirmatory Factor Analysis and Exploratory Structural Equation Modeling

Despite the limitations of overgeneralizing cutoff values for confirmatory factor analysis (CFA; e.g., Marsh, Hau, & Wen, 2004), they are still often employed as golden rules for assessing factorial validity in sport and exercise psychology. The purpose of this study was to investigate the appropriateness of using the CFA approach with these cutoff values for typical multidimensional measures. Furthermore, we ought to examine how a model could be respecified to achieve acceptable fit and explored whether exploratory structural equation modeling (ESEM) provides a more appropriate assessment of model fit. Six multidimensional measures commonly used in sport and exercise psychology research were examined using CFA and ESEM. Despite demonstrating good validity in previous research, all eight failed to meet the cutoff values proposed by Hu and Bentler. ESEM improved model fit in all measures. In conclusion, we suggest that model misfit in this study demonstrates the problem with interpreting cutoff values rigidly. Furthermore, we recommend ESEM as a preferred approach to examining model fit in multidimensional measures.     

Characterizing the mechanical parameters of forward and backward falls as experienced in snowboarding

Wrist injuries are frequently observed after falls in snowboarding. In this study, laboratory experiments mimicking forward and backward falls were analysed. In six different falling scenarios, participants self-initiated falls from a static initial position. Eighteen volunteers conducted a total of 741 trials. Measurements were taken for basic parameters describing the kinematics as well as the biomechanical loading during impact, such as impact force, impact acceleration, and velocity. The effective mass affecting the wrist in a fall also was determined. The elbow angle at impact showed a more extended arm in backward falls compared to forward falls, whereas the wrist angle at impact remained similar in forward and backward falls. The study results suggest a new performance standard for wrist guards, indicating the following parameters to characterize an impact: an effective mass acting on one wrist of 3–5 kg, an impact angle of 75° of the forearm relative to the ground, and an impact velocity of 3 m/s.     

The analysis of athletic performance: some practical and philosophical considerations

This article presents a hypothetical dialogue between a notational analyst (NA) recently schooled in the positivistic assessment of athletic performance, an ‘old-school’ traditional coach (TC) who favours subjective analysis, and a pragmatic educator (PE). The conversation opens with NA and TC debating the respective value of quantitative and qualitative methods of performance analysis. Having considered their arguments from a-distance, PE offers a philosophically underpinned point of view that helps to practically reconcile NA's and TC's opposing positions. While primarily focusing on practical issues relating to the analysis of athletic performance, PE contends that ‘quantitative’ and ‘qualitative’ approaches can be legitimately used in combination. Such a stance would appear in-line with a pragmatic philosophical perspective, which by focusing on practical issues embraces pluralistic methods. It is hoped that this dialogue will facilitate further philosophical and practical debate to generate knowledge that could enrich coaches' understanding by presenting an approach to performance analysis that is more realistic for practitioners.     

Civilising recalcitrant boys' bodies: pursuing social fitness through the anti-obesity offensive

Obesity discourse provides a commonly recycled rationale for multiple, ostensibly well-intended, interventions. Formal educational settings sometimes operate as sites for these biopedagogies which putatively promote ‘good health’ among young people as they transition to ‘responsible’ adulthood. Yet, regulation and control, or the pursuit of social fitness, may be more pressing concerns. Drawing from an ethnography of a ‘Health and Youth’ college initiative in Northeast England, directed at recalcitrant boys who risked school exclusion, this article considers how the war on obesity provided a rationale for middle-class efforts to instil civility. Despite educators' best intentions, the initiative also provided a stage and props for cruder forms of bullying among the boys. This article critiques (un)civilised fat oppression in this setting as part of a larger interrogation of the state sponsored anti-obesity offensive. Connections are made with literature on the civilising process, obesity discourse, boys' bodies, health and education.     

Validity of the X-factor computation methods and relationship between the X-factor parameters and clubhead velocity in skilled golfers

The purpose of this study was to assess the validity of the X-factor computation methods and to examine whether direct relationships exist between the X-factor parameters and the clubhead velocity in a group of skilled male golfers (n = 18, handicap = ? 0.6 ± 2.1). Five driver trials were captured from each golfer using an optical motion capture system (250 Hz). Two plane-based methods (conventional vs. functional swing plane-based) and one Cardan rotation-based method (relative orientation) were used to compute select X-factor (end of pelvis rotation, top of backswing, ball impact (BI), and maximum), X-factor stretch (stretch and maximum stretch), and X-factor velocity (BI and maximum) parameters. The maximum clubhead velocity was extracted and normalized to golfer's body height to eliminate the effect of body size. A one-way repeated MANOVA revealed that the computation methods generated significantly different X-factor parameter values (p < 0.001). The conventional method provided substantially larger X-factor values than the other methods in the untwisting phase and the meaningfulness of select X-factor parameters generated by this method was deemed questionable. The correlation analysis revealed that the X-factor parameters were not directly related to the maximum clubhead velocity (both unnormalized and normalized).     

Developing a pedagogical-technical framework to improve creative writing

There are many evidences of motivational and educational benefits from the use of learning software. However, there is a lack of study with regards to the teaching of creative writing. This paper aims to bridge the following gaps: first, the need for a proper framework for scaffolding creative writing through learning software; second, the lack of technical scaffolding in creative writing learning software; third, the need for customizable learning software that requires little programming knowledge; and fourth, personalized learning. To develop our initial framework, Merrill??s First Principles of Instruction is used as pedagogical scaffold and story setting, characters and story structure as component-based technical scaffolds. These were tested in a low-fidelity prototype. User testing indicates an increase in creativity, improvement in story development, clarity of ideas and language skills. We also derive two design principles, i.e. identity and interactivity. Based on these findings, a high-fidelity prototype, named Storyworld, is developed. T-test analyses on results indicate significant improvement in overall creative writing skills, as well as grammar, structure and creativity. The prototype utilizes component-based design in the technical scaffolds, which is encapsulated in a tidy framework that can be personalized for individual learning needs. Our most important contribution is a proper framework combining technical scaffolds and pedagogical scaffolds that not only makes learning more effective and motivating for students, but is also cost-effective in redesigning and personalizing lessons and systems.     

The social competence of highly gifted math and science adolescents

Involving 740 highly gifted math and science students from two different countries, Korea and the United States, this study examined how these gifted adolescents perceived their interpersonal ability and peer relationships and whether there were differences between these two groups by demographic variables. Based on the survey data, results showed that our gifted students perceived their interpersonal ability and peer relationships at levels comparable to or higher than those of their non-gifted counterparts. They were satisfied and confident with their peer relationships and did not identify negative effects of being gifted when forming and maintaining friendships. Differences were found between Korean and American students by gender in their profiles of interpersonal ability and peer relationships. Positive self-portrayal of social competence found for our sample disputed previous studies suggesting that highly gifted students tend to struggle with social relationships. Given that each group of students had different educational, linguistic, and cultural backgrounds, the results should also be interpreted with caution.
