A phenomenographic investigation on the use of iPads among undergraduate art and design students

The increasingly widespread use of iPads in higher education (HE) brings to the forefront questions about the contribution of these computer tablets towards teaching and learning. However, there is a noticeable gap of research on the instructional potential of iPads in HE. This paper describes the first stage of a research project on the use of iPads in undergraduate art and design disciplines, and is a collaboration between the research lab “Networked Learning Technologies in Art and Design” at Cyprus University of Technology, and the “Centre for Pedagogic Research” at Falmouth University in England. The participants from both institutions provided a student‐centred perspective, and the qualitative analysis (phenomenography) revealed varied perceptions. Based on the findings of this project, the implication is that there are a number of challenges and obstacles in embedding the use of iPads in art and design education. Further research in the second stage of this collaborative research will investigate the views and motivations of art and design faculty.

Effects of an 8-weeks erythropoietin treatment on mitochondrial and whole body fat oxidation capacity during exercise in healthy males

The present investigation was performed to elucidate if the non-erythropoietic ergogenic effect of a recombinant erythropoietin treatment results in an impact on skeletal muscle mitochondrial and whole body fatty acid oxidation capacity during exercise, myoglobin concentration and angiogenesis. Recombinant erythropoietin was administered by subcutaneous injections (5000 IU) in six healthy male volunteers (aged 21 ± 2 years; fat mass 18.5 ± 2.3%) over 8 weeks. The participants performed two graded cycle ergometer exercise tests before and after the intervention where VO_2max and maximal fat oxidation were measured. Biopsies of the vastus lateralis muscle were obtained before and after the intervention. Recombinant erythropoietin treatment increased mitochondrial O₂ flux during ADP stimulated state 3 respiration in the presence of complex I and II substrates (malate, glutamate, pyruvate, succinate) with additional electron input from β-oxidation (octanoylcarnitine) (from 60 ± 13 to 87 ± 24 pmol · s^?1 · mg^?1 P < 0.01). β-hydroxy-acyl-CoA-dehydrogenase activity was higher after treatment (P < 0.05), whereas citrate synthase activity also tended to increase (P = 0.06). Total myoglobin increased by 16.5% (P < 0.05). Capillaries per muscle area tended to increase (P = 0.07), whereas capillaries per fibre as well as the total expression of vascular endothelial growth factor remained unchanged. Whole body maximal fat oxidation was not increased after treatment. Eight weeks of recombinant erythropoietin treatment increases mitochondrial fatty acid oxidation capacity and myoglobin concentration without any effect on whole body maximal fat oxidation.     

Perpetuation of Whiteness Ideologies in U.S. College Student Discourse

Utilizing discourse from college students who participated in a three-day seminar on systemic racism, intersectionality, and white privilege, this study examines and critiques ideologies within college students’ discourse that are foundational to whiteness. Three ideological discourses emerged before, during, and after the seminar – Liberal Pluralism, Meritocracy, and “Reverse Racism.” The discourses were analysed using Critical Discourse Analysis and findings are presented from the study that include the implications of ideological discourses that perpetuate the pervasiveness of whiteness and white privilege. The paper concludes with implications for communication scholars and educators, most specifically those who teach intercultural communication.
