A Critical Review of Line Graphs in Behavior Analytic Journals

Visual displays such as graphs have played an instrumental role in psychology. One discipline relies almost exclusively on graphs in both applied and basic settings, behavior analysis. The most common graphic used in behavior analysis falls under the category of time series. The line graph represents the most frequently used display for visual analysis and subsequent interpretation and communication of experimental findings. Behavior analysis, like the rest of psychology, has opted to use non-standard line graphs. Therefore, the degree to which graphical quality occurs remains unknown. The current article surveys the essential structure and quality features of line graphs in behavioral journals. Four thousand three hundred and thirteen graphs from 11 journals served as the sample. Results of the survey indicate a high degree of deviation from standards of graph construction and proper labeling. A discussion of the problems associated with graphing errors, future directions for graphing in the field of behavior analysis, and the need for standards adopted for line graphs follows.     

Didactic and technical considerations when developing e-learning and CME

Several usability issues were encountered during the design of a blended e-learning program for a course in evidence-based medicine for general practice trainers. The program was developed in four steps. We focused in this article on step 2 and 3. Step 2 focused on which educational principles to apply, that is, which learning theories, instructional designs and other theories should influence the program. Step 3 focused on the design elements, namely whether to use hypermedia and/or multimedia, and what screen design and which font to use. This article presents the important issues in designing an e-course and provides an impression of the complexity of designing high quality e-learning in particular for continuing medical education (CME).     

It’s About Making Surfaces Invisible

Antireflection is an essential requirement for certain optoelectronic devices. Antireflective surfaces can be generated by different methods. One method mimics the nanofeatures on the moth eye surface. This can be done by ‘soft lithography’ (SL), where nanofeatures are created on an elastomeric stamp. This stamp is then used for imprinting the pattern on other surfaces.     

The development of Hyper-MNP: Hyper-media navigational performance scale

The present study aimed at developing a scale to evaluate navigational performance as a whole, which is one of the factors influencing learning in hyper media. In line with this purpose, depending on the related literature, an item pool of 15 factors was prepared, and these variables were decreased to 5 based on the views of 38 field experts. In the end, a 3-factor structured was obtained via a pilot application carried out with 32 Information Technologies (IT) students, via the confirmatory factor analysis conducted with 110 IT students and via the reliability analysis carried out with 33 IT students. The scale included 14 items, and the internal consistency coefficient regarding the whole scale was calculated as α?=?0.90. The results of the Pearson correlation analysis revealed that the test-retest correlation coefficients of the items ranged between 0.762 and 0.954. As a result of the analyses conducted, the Hyper-MNP scale was found to be a valid and reliable tool that can be used to measure the navigational performance in hyper media.     

Elite wheelchair rugby: a quantitative analysis of chair configuration in Australia

Limited recommendations of wheelchair configurations for court sports have been identified in the published literature. To accommodate the wide range of impairments in wheelchair rugby, players are given a point score that reflects their impairment. Players have regularly been grouped as high-, mid-, or low-point players in research, with high-point players having greater levels of muscle function compared with other classifications. This research documented the wheelchair configurations of elite Australian wheelchair rugby players across classification groups. Significant differences (p < 0.05) were found for increased seat height and decreased seat depth for high-point players compared with low- and mid-point groups, respectively. Low-point players displayed reduced wheelchair mass compared with high- and mid-point players, as well as increased frame length. Camber angles showed no significant differences across the classification groups. The incorporation of anthropometric measures, such as the elbow angle at the top dead center, was also investigated. While elbow angle showed no significant differences, seat height-to-total arm length ratio was higher for high-point players. Participants also completed surveys detailing their perception of the effect of altering wheelchair configurations. It is suggested that wheelchair configurations should consider an individual’s anthropometrics, impairment, training history, and court role to promote optimal performance, with predictive modeling having the potential to reduce the associated time and cost.     

Critical literacy: Beyond reason

In this paper, I argue that critical literacy is essentially a rationalist activity that does not sufficiently address the non-rational investments that readers bring with them to texts and tasks. I begin by looking at playful advertising texts that work with humour and the transgressive in order to consider the role of pleasure rather than reason. Then I examine the force of powerful identifications in relation to reason to show that educational interventions cannot ignore them. Finally, I tentatively suggest that we may need to find ways to combine socio-cultural and psycho-analytic theory in order to imagine new directions for pedagogy in the critical literacy classroom.     

The University as a community of selves: Johan Vilhelm Snellman's “On Academic Studies”

Nowadays we tend to regard the idea of a university as an outdated subject. The world of universities is today so complex and diverse that no general doctrine of the university seems possible. In a recent article Alasdair MacIntyre challenges this view and points out that by giving up the question “What is university?” we also give up the question “What is an educated mind?” In this article I will return to the old discussion on the idea of a university. I will go all the way back to Plato, but my main theme is J. V. Snellman’s essay On Academic Studies (1840). There Snellman, a young university lecturer at the time, defends his view that the university is a community of selves. The essay strongly emphasises that students should not only learn to know but also to act in a responsible way as selves. However, the text also reflects on Snellman’s own activity before the publication. He had defended academic freedom against the rector of the Imperial Alexander University of Finland. As a result, Snellman was in the end sentenced in an open court and forced to leave the university. Snellman’s view is certainly not the final definition of the university, but as it, besides presenting a theoretical view on the essence of the university, also reflects on activity in a university community, it gives us elements for reflecting on the idea of a university and an educated mind.
