Color vision in the giant panda (Ailuropoda melanoleuca)

Hue discrimination abilities of giant pandas were tested, controlling for brightness. Subjects were 2 adult giant pandas (1 male and 1 female). A simultaneous discrimination procedure without correction was used. In five tasks, white, black, and five saturations each of green, blue, and red served as positive stimuli that were paired with one or two comparison stimuli consisting of 16 saturations of gray. To demonstrate discrimination, the subjects were required to choose the positive stimulus in 16 of 20 trials (80% correct) for three consecutive sessions. Both subjects reached criterion for green and red. The female subject also reached criterion for blue. The male was not tested for blue. This study is a systematic replication of Bacon and Burghardt’s (1976) color discrimination experiment on black bears. The results suggest that color vision in the giant panda is comparable to that of black bears and other carnivores that are not strictly nocturnal.     

Get the cite right: Design and evaluation of a high-quality online citation tutorial

As part of a library initiative to foster information literacy, promote academic integrity, and prevent inadvertent plagiarism, a high-quality online tutorial was designed to teach students to cite sources properly. The development of this tutorial, APA Exposed: Everything You Always Wanted to Know About APA Format but Were Afraid to Ask, was a collaborative endeavor among research and instruction librarians, learning technology specialists, and an instructor. This study employs a mixed-methods research approach that combines the use of multiple data sources – an online survey, website visitor-tracking software, e-mail correspondence, and a Google search – to evaluate the quality and efficacy of the tutorial. Analyses of online survey data indicate 98% of survey respondents found the tutorial useful or very useful. All of the respondents reported the tutorial improved their understanding of APA style. In addition, 93% of respondents said they planned to use this tutorial as a reference resource in the future and 99% said they would recommend the tutorial to others. The online tutorial received an average of 1055 visits per month. The findings of this study indicate that there is a need for high-quality online citation instruction and that the tutorial meets this need. Providing effective citation instruction online not only benefits tutorial participants but also research and instruction librarians as they can now allocate limited library resources to areas of instruction other then proper citation techniques.     

A conceptual guide to natural history museum visitors' understanding of evolution

Museum visitors are an ideal population for assessing the persistence of the conceptual barriers that make it difficult to grasp Darwinian evolutionary theory. In comparison with other members of the public, they are more likely to be interested in natural history, have higher education levels, and be exposed to the relevant content. If museum visitors do not grasp evolutionary principles, it seems unlikely that other members of the general public would do so. In the current study, 32 systematically selected visitors to three Midwest museums of natural history provided detailed open‐ended explanations of biological change in seven diverse organisms. They were not told that these were evolutionary problems. Responses were coded as: informed naturalistic reasoning, featuring some understanding of key evolutionary concepts, novice naturalistic reasoning, featuring intuitive explanations that are also present in childhood, and creationist reasoning, featuring supernatural explanations. All visitors were mixed reasoners, using one or more of these patterns in different permutations across the seven organisms: 72% used a combination of informed naturalistic reasoning and novice naturalistic reasoning, while a further 28% added creationist reasoning to this mix. Correlational analyses indicated that for many visitors these reasoning patterns were coherent rather than fragmented. The theoretical model presented in this article contributes to an analysis of the developmental and cultural factors associated with these patterns. This could help educators working in diverse educational settings understand how to move visitors and students toward more informed reasoning patterns. © 2009 Wiley Periodicals, Inc.

Comparing ActiGraph equations for estimating energy expenditure in older adults

Accurate estimation of energy expenditure (EE) from accelerometer outputs remains a challenge in older adults. The aim of this study was to validate different ActiGraph (AG) equations for predicting EE in older adults. Forty older adults (age = 77.4 ± 8.1 yrs) completed a set of household/gardening activities in their residence, while wearing an AG at the hip (GT3X+) and a portable calorimeter (MetaMax 3B – criterion). Predicted EEs from AG were calculated using five equations (Freedson, refined Crouter, Sasaki and Santos-Lozano (vertical-axis, vectormagnitude)). Accuracy of equations was assessed using root-mean-square error (RMSE) and mean bias. The Sasaki equation showed the lowest RMSE for all activities (0.47 METs) and across physical activity intensities (PAIs) (range 0.18–0.48 METs). The Freedson and Santos-Lozano equations tended to overestimate EE for sedentary activities (range: 0.48 to 0.97 METs), while EEs for moderate-to-vigorous activities (MVPA) were underestimated (range: ?1.02 to ?0.64 METs). The refined Crouter and Sasaki equations showed no systematic bias, but they respectively overestimated and underestimated EE across PAIs. In conclusion, none of the equations was completely accurate for predicting EE across the range of PAIs. However, the refined Crouter and Sasaki equations showed better overall accuracy and precision when compared with the other methods.     

It's installed ... now get on with it! Looking beyond the software to the cultural change

This case study looks at the lessons learned from the ultimately successful implementation of the Blackboard Managed Learning Environment at Northumbria University and explores how these are now being applied to the matching implementation at a local further education college, which we are supporting. The study identifies key aspects that emerged from Northumbria's experience—the application of models of innovation from both educational and business worlds, the need to take account of the impact of cultural change, the need for effective staff development for all stakeholders, the need for a ‘road map’ for the development, and the need for ongoing dialogue with clients (staff) and customers (students). It reflects upon how Northumbria's approach has led to the emergence of a learning organisation that is adaptive and responsive and how a business approach can be applied to higher and further education innovations.     

The Challenge and Attainability of Goals for Adequate Yearly Progress

For standards-referenced assessment systems, there is a tension between setting high goals versus attainable ones for adequate yearly progress. The more relevant information that policymakers can consider in setting these goals, the more likely it will be that productive goals are set. Some strategies are presented here that can be used either singly or in combination to evaluate the level of rigor implied by these expectations. These strategies relate to understanding how likely it is, based on past experience, that a particular goal can be met.
