Scan and Learn: Quick Response Code Enabled Museum for Mobile Learning of Anatomy and Pathology

In the past, medical museums played a significant role in anatomy and pathology training. The attraction of medical museums has declined recently due to the emergence of information technology and innovative medical curricula. An innovative mobile learning platform has been developed using quick response (QR) codes for the museum specimens at the Lee Kong Chain School of Medicine, Singapore. High-quality images of the potted specimens were captured and combined into an album and a video using Adobe Acrobat Pro 9 and Windows Movie Maker, respectively. Subsequently, QR codes were generated linking to PDF documents with annotations, pathology, and clinical history concerning the specimens. Quick response codes were piloted in gastrointestinal teaching module for Year 2 medical students. Survey responses were obtained from students to verify the efficacy of QR as a learning tool. The majority of students either agreed or strongly agreed that it was easy to access the information about the specimen with QR codes (4.47 ± 0.84), while 96% of students agreed that they are able to correlate the specimen with the annotated images (4.56 ± 0.56). The majority of students (78%) agreed that QR codes are useful for their learning (4.22 ± 0.87), while 75% of students felt QR codes motivate them to visit Anatomy Resource Centre. Most of the students agreed that QR codes are useful for revision of materials (4.13 ± 1.07) and independent learning (4.38 ± 0.87). These findings suggest that QR codes are not only effective for students learning but also enhance their exploration experience with the museum specimens.     

The effectiveness of online instructional videos in the acquisition and demonstration of cognitive,affective and psychomotor rehabilitation skills

The use of instructional videos to teach clinical skills is an ever growing area of e‐learning based upon observational learning that is cited as one of the most basic yet powerful learning strategies. The aim of the current study is to evaluate the effectiveness of online instructional videos for the acquisition and demonstration of cognitive, affective and psychomotor skills among undergraduate students, throughout formative assessments with two different durations of instructional videos. The research suggests that the use of videos to support traditional learning should be encouraged. While a conclusive evidence—base for their usage has not yet been established they are a medium which is likely to benefit a proportion of a cohort, and it is very unlikely that they will be harmful to students' learning.     

Motor unit firing frequency of lower limb muscles during an incremental slide board skating test

This study investigated how the combination of workload and fatigue affected the frequency components of muscle activation and possible recruitment priority of motor units during skating to exhaustion. Ten male competitive speed skaters performed an incremental maximal test on a slide board. Activation of six muscles from the right leg was recorded throughout the test. A time-frequency analysis was performed to compute overall, high, and low frequency bands from the whole signal at 10, 40, 70, and 90% of total test time. Overall activation increased for all muscles throughout the test (p < 0.05 and ES > 0.80). There was an increase in low frequency (90 vs. 10%, p = 0.035, ES = 1.06) and a decrease in high frequency (90 vs. 10%, p = 0.009, ES = 1.38, and 90 vs. 40%, p = 0.025, ES = 1.12) components of gluteus maximus. Strong correlations were found between the maximal cadence and vastus lateralis, gluteus maximus and gluteus medius activation at the end of the test. In conclusion, the incremental skating test lead to an increase in activation of lower limb muscles, but only gluteus maximus was sensitive to changes in frequency components, probably caused by a pronounced fatigue.     

Exposing Privilege and Racism in The Great White North: Tackling Whiteness and Identity Issues in Canadian Education

As social justice–oriented teachers and teacher educators, it can seem as if we are fighting a losing battle against neoliberal education policies designed to disrupt and dismantle our field. In this article we draw upon traditions of critical race theory, counterstorying, and critical hope to examine the complex realities of contemporary teacher education and envision an alternate reality in which our profession develops and thrives. To do so, we first present a series of autoethnographic critical case studies that highlight dilemmas of practice. We then invite readers to examine each case through multiple lenses, as they grapple with the complexities of a visionary path forward. In so doing, we offer tools for critical professional development that articulate, deconstruct, and reimagine social justice–oriented teacher education and activism in this changing landscape. We close with recommendations to increase our collective capacity as social justice teacher educators, placing a central emphasis on the need for community, critical professional development, and hope.     

Effects of movement velocity and training frequency of resistance exercise on functional performance in older adults: a randomised controlled trial

Objectives: To investigate the effects that high-velocity, low-load (HVLL) and low-velocity, high-load (LVHL) resistance exercise, performed once or twice-weekly, have on indices of functional performance (primary outcome), maximal strength, and body composition (secondary outcomes) in older adults.

Methods: In a randomised, controlled, multi-armed, parallel design, 54 moderately-highly active, but resistance exercise naïve older adults (aged 60–79 years), attended baseline and post-10-week intervention assessment sessions. Physical and functional assessments were completed, and predicted one-repetition maximums (1-RM) were obtained for eight exercises. Participants were then randomised into one of five conditions: HVLL once-weekly (HVLL1: n?=?11) or twice-weekly (HVLL2: n?=?11), LVHL once-weekly (LVHL1: n?=?10) or twice-weekly (LVHL2: n?=?11), no-exercise control condition (CON: n?=?11). The HVLL conditions completed 3 sets of 14 repetitions at 40% 1-RM and the LVHL conditions, 3 sets of 7 repetitions at 80% 1-RM. In total, 50 participants completed all testing and were included in analyses.

Results: Only LVHL2 improved 30-sec chair stand performance (p?=?.035; g?=?0.89), arm curls (p?=?.011; g?=?1.65) and grip-strength (p?=?.015; g?=?0.34) compared to CON. LVHL2 improved maximal strength compared to CON for 7/8 exercises (p?p?Conclusion: Possibly due to the lower intensity nature of the HVLL conditions, LVHL, twice-weekly was most beneficial for improving functional performance and strength in moderately-highly active older adults. Therefore, we recommend that exercise professionals ensure resistance exercise sessions have sufficient intensity of effort and volume, in order to maximise functional performance and strength gains in older adults.     

A test of the poor leader-member relation cells of the contingency model on elementary school children.

The problem was to investigate the 4 poor leader-membrane relation cells of Fiedler's contingency model on fourth-grade elementary school groups. High and low least-preferred co-worker (LPC) leaders with strong and weak power were compared on structured and unstructured group tasks. When the task was structured, high LPC leaders were more effective than low regardless of position power. For the unstructured task, high LPC leaders were more effective than low for strong position power on 2 of 4 measures used, while low LPC leaders were more effective than high for weak position power on 1 of 4 measures.     

Modes of Engagement Among Diasporic Audiences of Asian New Zealand Film

The formation of a diasporic community within a host society may be signalled through community members’ creative contributions in the realm of cultural production. The ways in which diasporic audiences engage with diasporic cultural texts potentially offers social and cultural trajectories of their understandings of themselves as they negotiate their new environment. This article examines these trajectories, focusing on the ways New Zealand audiences of Asian descent engage with Asian diasporic films. It addresses three key questions: How do audiences’ referential reflections on diasporic films intersect with and contribute to their diasporic journeys and perceptions of themselves in New Zealand society? What kinds of values and beliefs do diasporic audiences feel are important to affirm and negotiate, both within representations of diasporic communities and in their New Zealand-based lives? And what roles do diasporic films play in this ongoing negotiation process?     

There is an "I" in TEAM: narcissism and social loafing

We investigated narcissism as a moderator of social loafing on a physical performance task. High and low narcissistic individuals twice performed a cycling task in same-sex teams of three: once when identifiability was low; and once when identifiability was high. A significant interaction between narcissism and identifiability was revealed, F(1, 40) = 4.09, p < .05, eta2 = .09 for performance. Follow-up tests indicated that high narcissists' performance significantly increased with greater identifiability, whereas low narcissists displayed no such performance differences. Results suggested that this effect was due to an increase in narcissists' on-task effort (ratings of perceived exertion and heart rate) when they knew that their performance was to be identified.     

Baby boomers engagement as traditional university students: benefits and costs

This study draws from interviews of baby boomers (born between 1946 and 1965) enrolled in a traditional university programme. Interviews focussed on the mental, social and physical benefits of university education, exploring the aspirations of baby boomers as well as the social and academic barriers and costs they encountered. This qualitative phenomenological study investigated the perceptions, understandings and beliefs of 15 baby boomers from South-East Queensland who were returning to or commencing university level education. Informal semi-structured interviews were conducted and thematically analysed to provide a detailed account of the baby boomer students’ university experience. Using an adapted health action process approach, with the health goal being replaced by a learning goal, the results confirm that university study in later life can be beneficial to the individual as well as to the wider community. This research can inform policy-making by emphasising the importance of lifelong learning and healthy ageing for the baby boomer generation. The results highlight the value of higher education creating a supportive environment for baby boomer students which, in addition to educational achievements, can assist participants in maintaining good health and making informed health care decisions in the future.
