    Field Trip! Assessing Business Student Interest in Plant Tours and Their Product Categories

    Get PDF
    Business educators are challenged daily to provide fresh ideas in the classroom and to use new methods to stimulate active learning. One option is to use manufacturing plant tours, company museums, and company visitor centers to supplement traditional classroom activities. This manuscript details this growing type of tourism (known as Consumer Experience Tourism) and identifies the product categories of greatest interest to today’s students in Business and Economics. Business educators are encouraged to more fully embrace this under-utilized resource to promote active student learning and to select those destinations of greatest interest to their particular student audiences

    Patterns of neural response in scene-selective regions of the human brain are affected by low-level manipulations of spatial frequency

    Neuroimaging studies have found distinct patterns of response to different categories of scenes. However, the relative importance of low-level image properties in generating these response patterns is not fully understood. To address this issue, we directly manipulated the low level properties of scenes in a way that preserved the ability to perceive the category. We then measured the effect of these manipulations on category-selective patterns of fMRI response in the PPA, RSC and OPA. In Experiment 1, a horizontal-pass or vertical-pass orientation filter was applied to images of indoor and natural scenes. The image filter did not have a large effect on the patterns of response. For example, vertical- and horizontal-pass filtered indoor images generated similar patterns of response. Similarly, vertical- and horizontal-pass filtered natural scenes generated similar patterns of response. In Experiment 2, low-pass or high-pass spatial frequency filters were applied to the images. We found that image filter had a marked effect on the patterns of response in scene-selective regions. For example, low-pass indoor images generated similar patterns of response to low-pass natural images. The effect of filter varied across different scene-selective regions, suggesting differences in the way that scenes are represented in these regions. These results indicate that patterns of response in scene-selective regions are sensitive to the low-level properties of the image, particularly the spatial frequency content

    Perceptions of New Member Academic Engagement: A Mixed Methods Case Study

    Get PDF
    A mixed methods case study was conducted to triangulate a comprehensive assessment of the perceptions of fraternity/sorority life from three different stakeholders on a liberal arts campus. Three electronic surveys were sent to selected groups that asked respondents to provide perceptions of the academic engagement of affiliated students on the campus. In addition, affiliated student’s grade point averages were monitored across three semesters to determine if there was a marked change in academic performance while going through the new member education process. Results showed that new member academic performance was similar across the semester prior to, during, and after the new member experience. Survey results showed differences in perception of affiliated students’ academic engagement by group surveyed, and provided sources of common interest to promote greater understanding between stakeholder groups

    A data driven approach to understanding the organization of high-level visual cortex

    Get PDF
    The neural representation in scene-selective regions of human visual cortex, such as the PPA, has been linked to the semantic and categorical properties of the images. However, the extent to which patterns of neural response in these regions reflect more fundamental organizing principles is not yet clear. Existing studies generally employ stimulus conditions chosen by the experimenter, potentially obscuring the contribution of more basic stimulus dimensions. To address this issue, we used a data-driven approach to describe a large database of scenes (>100,000 images) in terms of their visual properties (orientation, spatial frequency, spatial location). K-means clustering was then used to select images from distinct regions of this feature space. Images in each cluster did not correspond to typical scene categories. Nevertheless, they elicited distinct patterns of neural response in the PPA. Moreover, the similarity of the neural response to different clusters in the PPA could be predicted by the similarity in their image properties. Interestingly, the neural response in the PPA was also predicted by perceptual responses to the scenes, but not by their semantic properties. These findings provide an image-based explanation for the emergence of higher-level representations in scene-selective regions of the human brain

A definitive version was subsequently published in Soil Biology and Biochemistry, Vol. 63, pp. 1 – 4 DOI: http://dx.doi.org/10.1016/j.soilbio.2013.03.011In arctic ecosystems, winter soil respiration can contribute substantially to annual CO2 release, yet the source of this C is not clear. We analysed the 14C content of C released from plant-free plots in mountain birch forest and tundra-heath. Winter-respired CO2 was found to be a similar age (tundra) or older (forest) than C released during the previous autumn. Overall, our study demonstrates that the decomposition of older C can continue during the winter, in these two contrasting arctic ecosystems

    No evidence for compensatory thermal adaptation of soil microbial respiration in the study of Bradford et al. (2008)

    Get PDF
    Bradford et al. (2008) conclude that thermal adaptation will reduce the response of soil microbial respiration to rising global temperatures. However, we question both the methods used to calculate mass-specific respiration rates and the interpretation of the results. No clear evidence of thermal adaptation reducing soil microbial activity was produced

    Elements of construction: Minecraft and the periodic table

    Get PDF
    Minecraft is a popular computer game that allows the construction of almost limitless creations, and is used in learning contexts around the world. The widespread appeal and familiarity of the game makes it ideal for engaging children and young people with topics that might not otherwise interest them. With this in mind, the Science Hunters project, with support from a Royal Society of Chemistry (RSC) Outreach Fund grant, developed five Minecraft-based informal learning and engagement sessions about the periodic table, carbon, helium, uranium and gold, as part of the 2019 International Year of the Periodic Table (IYPT)
