The acute effects of two different self-myofascial release products on the calf muscle pump and plantar flexion ankle range of motion

textBackground: Massage can promote healing and recovery following exercise. (Carefelli et al. 1992). Barnes (1990) proposed that myofascial release helps to break up fibrotic fascial adhesions that may restrict joint range of motion (ROM). Self-myofascial release (SMR) is a type of massage that uses a roller and an individuals body weight to produce massage like loading over a specific anatomical area. Viscoelastic properties of muscle tissue extensibility increase during an acute bout (15 minutes) of massage-like loading (Haas et al 2012). Self-massage on the calves reduced pain and edema of the calves on nurses after an 8.5-hour work shift (Oh and Yoon 2008). Increasing blood flow through skeletal muscle will lead to increased oxygen delivery, which can increase healing and return to homeostasis post-exercise. Different shapes and densities of SMR rollers may produce different outcomes (Johansson 1962, Curran et al. 2012). Hypothesis: TP Footballer will have a greater effect on popliteal artery blood flow volume and ankle ROM vs. the SPRI® foam roller. Methods: N = 21 subjects (10 male 11 female; 18-27). No current lower extremity injury (within one year). No exercise 48 hours prior to data collection. Exercise was defined as any rigorous physical activity lasting 30 minutes or longer. Subjects rested prone 20 minutes. Resting BF and AD measurements were taken with an 8-13 MHz probe via Sonosite Micromaxx Doppler Ultrasound. Ankle ROM taken with a goniometer (mean of 3x). Statistics: Two-way repeated measure ANOVA and Bonferroni test was used to compare pre-test and post-test measures across both treatment conditions with two types of rollers. The α level was set at 0.05. Results: No significant increases found using the SPRI® foam roller on variables of BF Volume, TAP and ROM in plantar flexion. Significant increases found with arterial diameter. Significant increases using the TP Therapy Products Footballer® on variables of: ROM in plantar flexion, blood flow volume, arterial diameter Conclusion: SPRI® foam roller and TP Footballer® significantly increased popliteal arterial diameter. The TP Therapy Products Footballer® increased blood flow volume immediately following TP Therapy Soleus Protocol. TP Therapy Products Footballer® increased ankle plantar flexion immediately following TP Therapy Soleus Protocol.Kinesiology and Health Educatio

The Knowledge Application and Utilization Framework Applied to Defense COTS: A Research Synthesis for Outsourced Innovation

Purpose -- Militaries of developing nations face increasing budget pressures, high operations tempo, a blitzing pace of technology, and adversaries that often meet or beat government capabilities using commercial off-the-shelf (COTS) technologies. The adoption of COTS products into defense acquisitions has been offered to help meet these challenges by essentially outsourcing new product development and innovation. This research summarizes extant research to develop a framework for managing the innovative and knowledge flows. Design/Methodology/Approach – A literature review of 62 sources was conducted with the objectives of identifying antecedents (barriers and facilitators) and consequences of COTS adoption. Findings – The DoD COTS literature predominantly consists of industry case studies, and there’s a strong need for further academically rigorous study. Extant rigorous research implicates the importance of the role of knowledge management to government innovative thinking that relies heavily on commercial suppliers. Research Limitations/Implications – Extant academically rigorous studies tend to depend on measures derived from work in information systems research, relying on user satisfaction as the outcome. Our findings indicate that user satisfaction has no relationship to COTS success; technically complex governmental purchases may be too distant from users or may have socio-economic goals that supersede user satisfaction. The knowledge acquisition and utilization framework worked well to explain the innovative process in COTS. Practical Implications – Where past research in the commercial context found technological knowledge to outweigh market knowledge in terms of importance, our research found the opposite. Managers either in government or marketing to government should be aware of the importance of market knowledge for defense COTS innovation, especially for commercial companies that work as system integrators. Originality/Value – From the literature emerged a framework of COTS product usage and a scale to measure COTS product appropriateness that should help to guide COTS product adoption decisions and to help manage COTS product implementations ex post

Electric Dipole Moments: A Global Analysis

We perform a global analysis of searches for the permanent electric dipole moments (EDMs) of the neutron, neutral atoms, and molecules in terms of six leptonic, semileptonic, and nonleptonic interactions involving photons, electrons, pions, and nucleons. Translating the results into fundamental CP-violating effective interactions through dimension six involving Standard Model particles, we obtain rough lower bounds on the scale of beyond the Standard Model CP-violating interactions ranging from 1.5 TeV for the electron EDM to 1300 TeV for the nuclear spin-independent electron-quark interaction. We show that future measurements involving systems or combinations of systems with complementary sensitivities to the low-energy parameters may extend the mass reach by an order of magnitude or more.Comment: 15 pages, 1 figur

Electronic Reverse Auctions: Spawning Procurement Innovation in the Context of Arab Culture

Government e-procurement initiatives have the potential to transform local institutions, but few studies have been published of strategies for implementing specific e-procurement tools, particularly involving procurement by a foreign government adapting to local culture in the Middle East/North Africa (MENA). This case describes procurement at a forward operating base (FOB) in Kuwait in support of operations in Iraq. The government procurers had to deal with a phenomenon unique to the MENA region: wasta. Wasta is a form of social capital that bestows power, influence, and connection to those who possess it, similar to guanxi in China. This study explores the value proposition and limitations of electronic reverse auctions (eRA) with the purpose of sharing best practices and lessons learned for government procurement in a MENA country. The public value framework provides valuable theoretical insights for the implementation of a new government e-procurement tool in a foreign country. In a culture dominated by wasta, the suppliers enjoyed the transparency and merit-based virtues of eRA’s that transferred successfully into the new cultural milieu: potential to increase transparency, competition, efficiency, and taxpayer savings. The practices provided herein are designed specifically to help buyers overcome structural barriers including training, organizational inertia, and a lack of eRA policy and guidance while implementing a new e-procurement tool in a foreign country

Utility Analysis for Multiple Selection Devices and Multiple Outcomes

Traditional utility analysis only calculates the value of a given selection procedure over random selection. This assumption is not only an inaccurate representation of staffing policy but leads to overestimates of a device\u27s value. This paper generates a new utility model that accounts for multiple selection devices and multiple criteria. The model is illustrated using previous utility analysis work and an actual case of secretarial employees with eight predictors and nine criteria. A final example also is provided which includes these advancements as well as other researchers\u27 advances in a combined utility model. Results reveal that accounting for multiple criteria and outcomes dramatically reduces the utility estimates of implementing new selection devices
