Can Inertial Measurement Units Be Used To Validly Measure Pelvis And Thorax Motion During Cricket Bowling?, Daniel Cottam, Steven Kosovich, Amity Campbell, Paul Davey, Peter Kent, Jay-Shian Tan, Bruce Elliott, Jacqueline Alderson

ISBS Proceedings Archive

Identifying lumbar injury risk amongst cricket bowlers is a challenge to those involved in the sport. Bowling technique injury risk factors concerning thoracic and pelvic motion have been identified by previous research that used three-dimensional (3D) retro-reflective (RR) motion analysis. Inertial measurement units (IMUs) are considered a feasible and more portable means of 3D motion analysis. However, the validity of IMU measurement of thorax and pelvis movement during bowling has not yet been fully determined. This study aimed to achieve this by comparing concurrent IMU and RR angle outputs. Results suggest that when RR coordinate systems are aligned with IMUs’ …

Open Science: A Review On Open Peer Review Literature, Oluwaseyi Wusu Nov 2018

Open Science: A Review On Open Peer Review Literature, Oluwaseyi Wusu

Library Philosophy and Practice (e-journal)

Peer review truly, is the king in scientific communication –however, traditional peer review has been accused of many irregularities such as inconsistency and unrealistic peer reviewing, methodology flaws, and the likes. Despite all these irregularities, scholars still believe in peer review but new ways of opening up peer reviews are encouraged. There were high levels of backing for most of the attributes of OPR, such as disclosing identities of reviewers, open reports, open interaction, open platform, commenting on the final-version of published articles or data. Furthermore, the idea of supplementing pre-publication peer review with some form of post-publication evaluation would …

Effect Of The Timing Of The Pole Plant On Energy Loss In The Pole Vault Take-Off, Nicholas P. Linthorne Nov 2018

Effect Of The Timing Of The Pole Plant On Energy Loss In The Pole Vault Take-Off, Nicholas P. Linthorne

ISBS Proceedings Archive

Some leading pole vault coaches recommend a late planting of the pole, at close to the instant of take-off. This technique is believed to reduce the energy lost during the take-off and produce a higher vault. The present study re-analysed data from a previous study in which male pole vaulters manipulated the timing of the pole plant. An individual analysis showed that the timing of the pole plant did not clearly affect the change in the total energy of the athlete/pole system during the take-off. This result suggests there might be no advantage in using a late pole plant. An …

Moving On Slopes: Issues And Challenges From A Biomechanical Perspective, Hermann Schwameder Nov 2018

Moving On Slopes: Issues And Challenges From A Biomechanical Perspective, Hermann Schwameder

ISBS Proceedings Archive

Moving on slopes is part of daily living locomotion, but also several sport disciplines are performed on inclined terrain. From a biomechanical perspective locomotion on slopes is a challenging task as additional work has to be done compared to locomotion on flat terrain. Moving downwards supports the locomotion due to gravity, however, steep slopes often lead to high speeds caused by the transfer of potential to kinetic energy. Then locomotion is accompanied with the challenge to control speed. Another issue is the aspect of joint loading when moving on slopes. An increase of potential or kinetic energy is associated with …

Beyond The Figure Of The Problem Gambler: Locating Race And Sovereignty Struggles In Everyday Cultural Spaces Of Gambling, Fiona Nicoll Nov 2018

Beyond The Figure Of The Problem Gambler: Locating Race And Sovereignty Struggles In Everyday Cultural Spaces Of Gambling, Fiona Nicoll

Journal of Law and Social Policy

As gambling has become a ubiquitous feature of many neoliberal capitalist societies, the problem gambler has become a familiar cultural figure, invoked in regulation, popular culture and everyday life. This article brings critical research on governmentality together with cultural studies and critical Indigenous scholarship on whiteness, race and sovereignty to understand the racial biopolitics of gambling beyond the individual subject of problem gambling. I argue that, for settler-colonial states, gambling plays a role in maintaining tropes of cultural representation and securing legal and political power within an overarching system of white racial entitlement. An investigation of cultural spaces and products …

Migration Through A Small Pore Disrupts Inactive Chromatin Organization In Neutrophil-Like Cells, Elsie C. Jacobson, Jo K. Perry, David S. Long, Ada L. Olins, Donald E. Olins, Bryon E. Wright, Mark H. Vickers, Justin M. O'Sullivan

Pharmaceutical Sciences Faculty Publications

Background: Mammalian cells are flexible and can rapidly change shape when they contract, adhere, or migrate. The nucleus must be stiff enough to withstand cytoskeletal forces, but flexible enough to remodel as the cell changes shape. This is particularly important for cells migrating through confined spaces, where the nuclear shape must change in order to fit through a constriction. This occurs many times in the life cycle of a neutrophil, which must protect its chromatin from damage and disruption associated with migration. Here we characterized the effects of constricted migration in neutrophil-like cells. Results: Total RNA sequencing identified that migration …

Population Dynamics And Genotypic Richness Of The Threatened Acropora Spp. And Their Hybrid In The U.S. Virgin Islands, Hannah F. Nylander-Asplin

HCNSO Student Theses and Dissertations

Since the 1980’s, there has been an unprecedented decline in the reef-building Caribbean corals, Acropora cervicornis and A. palmata, which has led to their listing as “threatened” under the U.S Endangered Species Act. Despite this protective status, these Acropora species continue to experience declines primarily attributed to disease, global climate change, and storm damage. Recent evidence suggests the hybrid of these threatened species (A. prolifera) is found at abundances similar to or higher than the parental species at many sites throughout the Caribbean. However, there is still much that is unknown as to how and why hybrids may …
