INFLUENCE OF JUMPING MEASURES AND SQUAT 1RM ON SPRINT SPEED IN RUGBY UNION PLAYERS

This study examined the relationship of countermovement (CMJ), squat (SJ), and rebound jumps (RBJ), estimated 1RM back squat (SQ), contact time (CT) and Reactive Strength Index (RSI) for the RBJ to 30 m sprint time of sub-elite, semi-professional Rugby Union players. The results show that with the exception of SQ and CT, all variables were significantly (p .575). The best determinant of predicting 30 m sprint time was RSI. The relationships of SJ, CMJ, and RBJ jump height and RSI to 30 m sprint time suggest that these rapid movements are all common in Rugby Union players. The results show that estimated 1 RM back squat has little influence on sprint performance

Scholarly Commons Annual Report 2018-2019

The global impact of Scholarly Commons grew again in 2018-19. Submissions increased by 25% over FY 18 and downloads grew by 50% in FY 19. New conferences, such as the President’s Art Exhibit and the Southeastern- Atlantic Regional Conference on Differential Equations, were added. The highlight of the year in terms of new conferences and events for the Daytona Beach staff on the team was the 2019 Digital Commons Southeast User Group meeting, which was not only hosted in Scholarly Commons but also took place on the Daytona Beach Campus on May 31. The goal to work with faculty and other groups on the three campuses to increase Open Educational Resources in Scholarly Commons was quite successful. The team added faculty-authored textbooks, open access textbooks adopted by faculty, and course packs, containing open access or library-licensed items. Interest in this initiative was strong enough to warrant a new librarian position and the Daytona Beach Campus welcomed new team member, Cassandra Konz in late May. In addition to this goal, the team also began to develop avenues for faculty to organize and provide open access to research datasets. The first objective of this goal was met with the creation of an area in Scholarly Commons for small datasets. With the new areas Scholarly Commons supports, the Oversight Team continues to adapt. In January the team welcomed new member, Jim Solti, representing Worldwide, with a special emphasis on incorporating OER into online courses. The team also began working with the newly-appointed Associate Provost for Research, Dr. Remzi Seker. As we welcomed our new colleagues, we also said goodbye to Special Projects Librarian, Jane Deighan, who retired in June. Jane has been part of the team from the beginning and certainly wins the prize for setting up the most SelectedWorks pages and facilitating submissions for faculty on all three campuses. She will be missed at our meetings but she leaves a strong and enduring legacy

RELIABILITY OF JUMP AND PERFORMANCE MEASURES IN RUGBY UNION PLAYERS

The current study examined the reliability of countermovement (CMJ), squat (SJ), and rebound jumps (RBJ) to sprint and estimated 1RM back squat (SQ) of sub-elite Rugby Union players drawn from two teams of similar competitive level. Comparisons of mean performance on all tests were made via Student t-tests. The three trial reliability of jump height for the SJ, CMJ, RBJ, contact time (CT) and Reactive Strength Index for the RBJ, T-Test agility run (TA-Test), 30 and 36.58 m (40 yd) sprint times were estimated via ICC and ReANOVA. All variables displayed Average measures ICC ≥ .900; and except for the TA-Test, the three trials did not differ from each other. The performance of the two teams was found to be similar on all tests except the 30 m and 40 yd sprint tests. All the studied performance measures could be reliably assessed with one trial, except the TA-test

Digital Repository Concierge @ Your Service

Libraries often develop and implement new services for the public. Sometimes they succeed; other times they fail. Expecting community members to understand the benefits of a great new idea on their own may not always work. But, taking a concierge approach to the implementation and maintenance of an innovative service may make all the difference to its success. Using a case study from the Embry-Riddle Aeronautical University (ERAU) library as a backdrop, this presentation will highlight the effectiveness of taking a concierge approach to implementing a new service in any type of library. In 2013, ERAU launched Scholarly Commons to gather and provide open access to faculty and student research. Library administration was concerned that initial response from the university community might be slow based on the experience of other institutional repositories. Faculty who might be willing to submit their work to an open access repository often did not engage due to concerns about copyright violation, plagiarism, perceived quality of “free” online resources, or simply lack of time and inclination to learn something new. After researching different approaches other academic libraries took to support similar repositories, ERAU decided to offer a concierge approach to developing Scholarly Commons. Librarians would be available to help members of the community through every step of the process from locating copyright permission to submission. In the seven years of its existence, Scholarly Commons has grown to include journals and magazines, conferences, open educational resources, and datasets, all of which are supported by library staff. Members of the library concierge team will highlight their part in implementing and maintaining this very successful innovative service

Scholarly Commons Annual Report 2017-2018

Scholarly Commons continues to showcase ERAU research globally. While the number of submissions increased by 11.85% over FY 17, downloads grew by 43.89% in FY 18. In addition, new conferences, such as the 2018 International Civil Aviation English Association (ICAEA) and ERAU’s AviAsian Conference, were added. The annual ICAEA Conference is held in a different international location each year and the Daytona Beach Campus served as the host this year. The AviAsian Conference is sponsored on ERAU’s Singapore Campus by faculty from that area

Momentum Distributions of Particles from Three--Body Halo Fragmentation: Final State Interactions

Momentum distributions of particles from nuclear break-up of fast three-body halos are calculated consistently, and applied to $^{11}$Li. The same two-body interactions between the three particles are used to calculate the ground state structure and the final state of the reaction processes. We reproduce the available momentum distributions from $^{11}$Li fragmentation, together with the size and energy of $^{11}$Li, with a neutron-core relative state containing a $p$-state admixture of 20\%-30\%. The available fragmentation data strongly suggest an $s$-state in $^{10}$Li at about 50 keV, and indicate a $p$-state around 500 keV.Comment: 11 pages (RevTeX), 3 Postscript figures (uuencoded postscript file attached at the end of the LaTeX file).

Functional characterization of GABAA receptor-mediated modulation of cortical neuron network activity in microelectrode array recordings

The numerous γ-aminobutyric acid type A receptor (GABAAR) subtypes are differentially expressed and mediate distinct functions at neuronal level. In this study we have investigated GABAAR-mediated modulation of the spontaneous activity patterns of primary neuronal networks from murine frontal cortex by characterizing the effects induced by a wide selection of pharmacological tools at a plethora of activity parameters in microelectrode array (MEA) recordings. The basic characteristics of the primary cortical neurons used in the recordings were studied in some detail, and the expression levels of various GABAAR subunits were investigated by western blotting and RT-qPCR. In the MEA recordings, the pan-GABAAR agonist muscimol and the GABABR agonist baclofen were observed to mediate phenotypically distinct changes in cortical network activity. Selective augmentation of αβγ GABAAR signaling by diazepam and of δ-containing GABAAR (δ-GABAAR) signaling by DS1 produced pronounced changes in the majority of the activity parameters, both drugs mediating similar patterns of activity changes as muscimol. The apparent importance of δ-GABAAR signaling for network activity was largely corroborated by the effects induced by the functionally selective δ-GABAAR agonists THIP and Thio-THIP, whereas the δ-GABAAR selective potentiator DS2 only mediated modest effects on network activity, even when co-applied with low THIP concentrations. Interestingly, diazepam exhibited dramatically right-shifted concentration-response relationships at many of the activity parameters when co-applied with a trace concentration of DS1 compared to when applied alone. In contrast, the potencies and efficacies displayed by DS1 at the networks were not substantially altered by the concomitant presence of diazepam. In conclusion, the holistic nature of the information extractable from the MEA recordings offers interesting insights into the contributions of various GABAAR subtypes/subgroups to cortical network activity and the putative functional interplay between these receptors in these neurons
