Iterative approach to implicit student-generated mobile learning to promote visual literacy and peer mediated learning
This paper aims to report early findings of the second iteration of an implicit student-generated mobile learning project that promotes visual literacy and peer mediated learning. The first iteration was conducted with first year health science students at the University of Queensland, Australia, in 2013. We found that while the video assessment task may have aided learning for each student around their specific chosen topic, overall course learning outcomes did not improve. This was perhaps due to a failure of the peer mediated learning aspect of the learning activity. Furthermore, the labour intensive nature of the task may have attenuated overall performance in the course. Acting on these findings, we adjusted the visually based, peer-to-peer mobile learning activity accordingly. The revised assessment task was reintroduced in 2nd semester 2014, and early findings on the efficacy of the revised task on learning will be presented at the ascilite 2014 conference
Professional Identity of Undergraduate Occupational Therapy Students
Throughout the development of an individual, their identity, or how they see themselves, frequently changes. An important part of identity formation in adolescents is the development of professional identity, which is how they perceive themselves in a professional context. The establishment of a strong professional identity has been linked to life satisfaction, psychological well-being and success in one’s chosen career. The aim of this study was to identify the extent of professional identity development in second year undergraduate occupational therapy students. As part of an assessment task, students were asked to describe why they chose occupational therapy, how they saw themselves as occupational therapists, and to describe their role models. A thematic analysis of consenting students’ (n=59) responses was performed and each student ranked based on the strength of their professional identity. The results indicated that the stage of professional identity development of second year occupational therapy students varied considerably, despite them being at the same stage of their program. A quarter of students had advanced professional identity, while almost two-thirds were still developing. Students also provided detailed insights regarding the factors influencing their professional identity. Students with strong, positive influences regarding their choice to study occupational therapy were likely to have strong role models. Given its impact on well-being and career success, it is essential to identify students who may be at risk of poor professional identity. The methods developed here could be used to identify such students and to evaluate the success of educational interventions aimed at them
Iterative design and delivery of high impact, multiple platform, scenario-based interactive mobile learning activities in the health sciences.
Mobile learning is an iterative process which follows the action-reflection model of action learning. In mobile learning, the drivers of this model are both new technologies and evidence of the efficacy of specific activities. This paper reports the second phase of The Virtual Human Body (VHB) project, a long running mlearning undertaking at The University of Queensland in the use of scenario-based activities in the teaching of biomedical sciences. Early results from this phase of the project reaffirm that active mlearning activities need to be scalable in order to be universally accessible, and that a web-based design system allows the leverage of diverse, student-owned technology for academic benefit, permitting simple and easy adaption to new technologies, while literally providing a template for curriculum innovation, in terms of both flexibility of delivery, and dissemination to other curricula
Methods for sequential resonance assignment in solid, uniformly 13C, 15N labelled peptides: Quantification and application to antamanide
The application of adiabatic polarization-transfer experiments to resonance assignment in solid, uniformly 13C-15N-labelled polypeptides is demonstrated for the cyclic decapeptide antamanide. A homonuclear correlation experiment employing the DREAM sequence for adiabatic dipolar transfer yields a complete assignment of the Cα and aliphatic side-chain 13C resonances to amino acid types. The same information can be obtained from a TOBSY experiment using the recently introduced P91 12 TOBSY sequence, which employs the J couplings as a transfer mechanism. A comparison of the two methods is presented. Except for some aromatic phenylalanine resonances, a complete sequence-specific assignment of the 13C and 15N resonances in antamanide is achieved by a series of selective or broadband adiabatic triple-resonance experiments. Heteronuclear transfer by adiabatic-passage Hartmann-Hahn cross polarization is combined with adiabatic homonuclear transfer by the DREAM and rotational-resonance tickling sequences into two- and three-dimensional experiments. The performance of these experiments is evaluated quantitativel
How authentic is it? Evaluating the products of an authentic assessment task
[EN] Authentic assessment tasks resemble activities that are practiced in the workforce. These tasks are valued because they represent what students wish to accomplish as professionals, positively influencing their aspirations and motivations by explicitly demonstrating relevance of assessment tasks. However, given the choice available to students in completing authentic tasks and novelty of outcomes, the products of such assessment may vary in authenticity. This study aimed to develop a method of evaluating authenticity in student assessment products. Second year occupational therapy students (n=59) completed a written factsheet assignment about a disease or condition. The students’ products were evaluated for authenticity using a novel rubric developed during the study. The results demonstrate that authenticity in the product of an authentic assessment task is measurable, but varies widely across a cohort, with most products demonstrating moderate to high authenticity. However, there was no correlation between authenticity and course grade. Neither was there a correlation between the grade for this authentic task and a verbal authentic task in another course. These findings suggest that students, at this stage of their education, may not yet have progressed from writing like a professional to acting like one.Gray, H.; Colthorpe, K.; Ernst, H.; Ainscough, L.

Complementarity Assessment of South Greenland Katabatic Flows and West Europe Wind Regimes
Current global environmental challenges require vigorous and diverse actions
in the energy sector. One solution that has recently attracted interest
consists in harnessing high-quality variable renewable energy resources in
remote locations, while using transmission links to transport the power to end
users. In this context, a comparison of western European and Greenland wind
regimes is proposed. By leveraging a regional atmospheric model specifically
designed to accurately capture polar phenomena, local climatic features of
southern Greenland are identified to be particularly conducive to extensive
renewable electricity generation from wind. A methodology to assess how
connecting remote locations to major demand centres would benefit the latter
from a resource availability standpoint is introduced and applied to the
aforementioned Europe-Greenland case study, showing superior and complementary
wind generation potential in the considered region of Greenland with respect to
selected European sites.Comment: Published in Elsevier Energ
Thermal expansion and Gr\"uneisen parameters of Ba(Fe1-xCox)2As2 - a thermodynamic quest for quantum criticality
Thermal expansion data are used to study the uniaxial pressure dependence of
the electronic/magnetic entropy of Ba(Fe1-xCox)2As2. Uniaxial pressure is found
to be proportional to doping and, thus, also an appropriate tuning parameter in
this system. Many of the features predicted to occur for a pressure-tuned
quantum critical system, in which superconductivity is an emergent phase hiding
the critical point, are observed. The electronic/magnetic Gr\"uneisen
parameters associated with the spin-density wave and superconducting
transitions further demonstrate an intimate connection between both ordering
phenomena.Comment: 13 pages, 4 figure
Doping evolution of superconducting gaps and electronic densities of states in Ba(Fe1-xCox)2As2 iron pnictides
An extensive calorimetric study of the normal- and superconducting-state
properties of Ba(Fe1-xCox)2As2 is presented for 0 < x < 0.2. The normal-state
Sommerfeld coefficient increases (decreases) with Co doping for x
0.06), which illustrates the strong competition between magnetism and
superconductivity to monopolize the Fermi surface in the underdoped region and
the filling of the hole bands for overdoped Ba(Fe1-xCox)2As2. All
superconducting samples exhibit a residual electronic density of states of
unknown origin in the zero-temperature limit, which is minimal at optimal
doping but increases to the normal-state value in the strongly under- and
over-doped regions. The remaining specific heat in the superconducting state is
well described using a two-band model with isotropic s-wave superconducting
gaps.Comment: Submitted to Europhysics Letter
Systematic genetic analysis of the MHC region reveals mechanistic underpinnings of HLA type associations with disease.
The MHC region is highly associated with autoimmune and infectious diseases. Here we conduct an in-depth interrogation of associations between genetic variation, gene expression and disease. We create a comprehensive map of regulatory variation in the MHC region using WGS from 419 individuals to call eight-digit HLA types and RNA-seq data from matched iPSCs. Building on this regulatory map, we explored GWAS signals for 4083 traits, detecting colocalization for 180 disease loci with eQTLs. We show that eQTL analyses taking HLA type haplotypes into account have substantially greater power compared with only using single variants. We examined the association between the 8.1 ancestral haplotype and delayed colonization in Cystic Fibrosis, postulating that downregulation of RNF5 expression is the likely causal mechanism. Our study provides insights into the genetic architecture of the MHC region and pinpoints disease associations that are due to differential expression of HLA genes and non-HLA genes
