Visualization: The next generation

The purpose of this study was to determine whether adding an educational component to visualization (a procedure designed to reduce public speaking apprehension) increases the effectiveness of visualization. These data indicate that combining visualization and education is superior to either education or visualization alone or a no treatment control group in reducing self‐reported public speaking apprehension.     

A content analysis of local television newscasts: Answering the critics

Local television newscasts have been criticized for being too frivolous, but an analysis of San Diego stations indicates more newscast time is devoted to significant issues of the day than to anything else.     

Russian and East European Materials at the Sackner Archive of Concrete and Visual Poetry

This article provides an overview of the Russian and East European holdings at the Sackner Archive of Concrete and Visual Poetry in Miami, Florida. Materials held at the archive include rare and unique modernist books, samizdat and émigré publications, mail art, conceptual art, and recent artists’ books, mainly in Russian, Ukrainian, Czech, Polish, Serbian, and Hungarian.     

In sickness and in need: the how and why of special consideration for students

This article reviews the practice of special consideration for students who have been unable to complete examinations or assignments due to temporary incapacity such as illness or bereavement. A literature review revealed no meaningful academic discussion on the place of such special consideration in higher education. A broad overview of the international situation is presented and the courses of action used in various institutions are identified. While it is a widely accepted practice that some form of special consideration is offered to students, there is no generally argued justification for it. The key argument offered in this article is that special consideration can be offered while still being fair and while maintaining academic rigour. The broad social values that can be used to justify special academic consideration are presented, as are the general conditions which must exist for special consideration to be justified and verified. The paper closes with a brief review of potential further research in this area.     

Pre-training perceived wellness impacts training output in Australian football players

The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of ?1 corresponded to a ?4.9 ± 3.1 and ?8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of ?1 corresponded to a 0.43 ± 0.38 m·min^?1 and ?0.02 ± 0.01 au·min^?1 change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of ?1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session.     

Media and Occupational Aspirations: The Effect of Television on Career Aspirations of Adolescents

Vocational decisions are important decisions for adolescents. This article takes television effects into account. A literature review for the occupational world in TV programs reveals a strong focus on some occupations as well as small cultivation effects plus learning effects from mediated role models. A secondary analysis of 2 panel waves was undertaken to study the effect of media role models on occupational aspiration. Television usage in a program segment correlated with corresponding aspirations. A process models showed a strong effect of career aspiration in 1 panel wave on related television usage and career aspirations in the following panel wave.     

Software that assists learning within a complex abstract domain: the use of constraint and consequentiality as learning mechanisms

This paper describes a research project into undergraduates’ use of a software tool to learn symbolic logic—a complex abstract domain that has been shown to be intimidating for students. The software allows the students to manipulate proofs in certain ways and then calculates the consequences of their actions. A research method has been developed that allowed students’ use of this tool to be modelled, and this model was then used to identify, refine and create visual cues that provide support for students’ reasoning. The focus of this paper is the role of the software as an artefact to aid students’ visualisation of reasoning processes rather than the logic itself. The main mechanisms by which this visualisation is supported are the imposition of constraints on the actions available and the demonstration to students of the consequences of their actions. The study shows that the software encouraged experimentation with different routes to a proof, and constituted a challenge to fixated reasoning.
