Effects of Using Wedged-Weightlifting Shoes While Performing a Front Squat

Wedged-weightlifting shoes may contribute to a better squatting postural technique by allowing for an increase in ankle dorsiflexion, an increase in hip flexion, and a decrease in the amount of trunk lean. Purpose: To examine how wedged-weightlifting shoes affect peak power output, trunk lean, hip flexion, and ankle dorsiflexion during the performance of a front-squat. Methods: Six participants (167.875±20.13 lbs., 20.67±1.51 yrs.) completed five-repetition squatting trials while standing on a Bertec force plate. Force data were collected at 100 Hz using the Biopac Acknowledge system during these trials. Simultaneously, the trials were video recorded at 50 Hz in the sagittal plane. Five body landmarks (mid-trunk, hip, knee, ankle, base of the 5th metatarsal, and heel) were digitized using the Vicon Motus Motion Analysis System to generate a lower body model to measure lower extremity kinematics. Squatting trials were completed under two different shoe conditions (barefoot and wedged-weightlifting shoes) and two different loads (no-load and loaded at 50% 1RM). An initial laboratory visit two days prior to data collection was used to measure a 1RM. The middle three repetitions of the five-repetition sequence were analyzed. Ground reaction force data were used to determine peak positive and negative power during each squat repetition. Digitized position data were used to compute trunk, hip, knee and ankle joint angular kinematics. Results: A two-way repeated measure ANOVA was used to compare the shoe and load conditions. Shoe type (F(1,5)=7.81, p=.04, hp2=.61) and load (F(1,5)=24.72, p=.004) significantly affected peak negative power production. Load accounted for about 83% of the change seen in negative power production (hp2 =.832); as the load increased, the squatter’s negative power increased. Negative peak power occurs during the eccentric, or downward, movement of the squat. The means(SD) peak negative power output for wedge-weightlifting shoes, -1874.8(426.4) W, and load, -1242.0(417.1) W. Load (F(1,5)=18.94, p =.007) significantly affected the ankle angle and accounted for about 79% of change (hp2=.79), causing a decrease in ankle dorsiflexion. The mean(SD) ankle dorsiflexion under the load condition for wedged-weight lifting shoes, 50.9±(6.4)degrees, and barefoot, 49.71±(7.6)degrees. Conclusion: Although previous studies have suggested that wedged-weightlifting shoes affect performance of squatting, this study found that the wedged-weightlifting shoes did not affect the overall performance of the front squat

Temperature, Activity and Lizard Life Histories

Lizard life-history characteristics vary widely among species and populations. Most authors seek adaptive or phylogenetic explanations for life-history patterns, which are usually presumed to reflect genetic differences. However, lizard life histories are often phenotypically plastic, varying in response to temperature, food availability, and other environmental factors. Despite the importance of temperature to lizard ecology and physiology, its effects on life histories have received relatively little attention. We present a theoretical model predicting the proximate consequences of the thermal environment for lizard life histories. Temperature, by affecting activity times, can cause variation in annual survival rate and fecundity, leading to a negative correlation between survival rate and fecundity among populations in different thermal environments. Thus, physiological and evolutionary models predict the same qualitative pattern of life-history variation in lizards. We tested our model with published life-history data from field studies of the lizard Sceloporus undulatus, using climate and geographical data to reconstruct estimated annual activity seasons. Among populations, annual activity times were negatively correlated with annual survival rate and positively correlated with fecundity. Proximate effects of temperature may confound comparative analyses of lizard life-history variation and should be included in future evolutionary models

Gambelia Wislizenii (Long-nosed Leopard Lizard). Arboreal behavior.

In the North American southwest, leopard lizards (genus Gambelia) are characteristically ground dwelling (Stebbins 2003. A Field Guide to Western Reptiles and Amphibians, 3rd ed., Houghton-Mifflin, New York. 533 pp.; Smith 1946. Handbook of Lizards, Comstock Publishing Co., Ithaca, New York. 557 pp.). In G. wislizenii, climbing is not mentioned in several substantive ecological studies of this species (Parker and Pianka 1976. Herpetologica 32:95-114; Tanner and Krogh 1974. Herpetologica 30:63-72), and to our knowledge, only a few seconds exist of climbing in this species. Clark (1974. Trans. Kansas Acad. Sci. 77:68) observed a G. wislizenii perched 30 cm off the ground in a shrub, and Miller and Stebbins (1964. The Lives of Desert Animals in Joshua Tree National Monument,. University of California Press, Berkeley. 452 pp.) mentioned collecting an individual on top of a massive rock 30 feet from the ground. Crowley and Pietruszka (1983. Anim. Behav. 31:1055-1060) commented that this species often climbs into shrubs or onto rocks, but did not provide additional information. For this reason, we augment the limited data on climbing in G. wislizenii with an observation from the Mojave Desert of California (USA)

An Exploratory Study of Forces and Frictions affecting Large-Scale Model-Driven Development

In this paper, we investigate model-driven engineering, reporting on an exploratory case-study conducted at a large automotive company. The study consisted of interviews with 20 engineers and managers working in different roles. We found that, in the context of a large organization, contextual forces dominate the cognitive issues of using model-driven technology. The four forces we identified that are likely independent of the particular abstractions chosen as the basis of software development are the need for diffing in software product lines, the needs for problem-specific languages and types, the need for live modeling in exploratory activities, and the need for point-to-point traceability between artifacts. We also identified triggers of accidental complexity, which we refer to as points of friction introduced by languages and tools. Examples of the friction points identified are insufficient support for model diffing, point-to-point traceability, and model changes at runtime.Comment: To appear in proceedings of MODELS 2012, LNCS Springe

Principal investigator in a box: Version 1.2 documentation

Principal Investigator (PI) in a box is a computer system designed to help optimize the scientific results of experiments that are performed in space. The system will assist the astronaut experimenters in the collection and analysis of experimental data, recognition and pursuit of 'interesting' results, optimal use of the time allocated to the experiment, and troubleshooting of the experiment apparatus. This document discusses the problems that motivate development of 'PI-in-a-box', and presents a high- level system overview and a detailed description of each of the modules that comprise the current version of the system

Oral health in relation to all-cause mortality: the IPC cohort study

We evaluated the association between oral health and mortality. The study population comprised 76,188 subjects aged 16–89 years at recruitment. The mean follow-up time was 3.4 ± 2.4 years. Subjects with a personal medical history of cancer or cardiovascular disease and death by casualty were excluded from the analysis. A full-mouth clinical examination was performed in order to assess dental plaque, dental calculus and gingival inflammation. The number of teeth and functional masticatory units 10 missing teeth and functional masticatory units 10 missing teeth (HR = 2.31, [95% CI: 1.40–3.82]) and functional masticatory units <5 (HR = 2.40 [95% CI 1.55–3.73]). Moreover, when ≥3 oral diseases were cumulated in the model, the risk increased for all-cause mortality (HR = 3.39, [95% CI: 2.51–5.42]), all-cancer mortality (HR = 3.59, [95% CI: 1.23–10.05]) and non-cardiovascular and non-cancer mortality (HR = 4.71, [95% CI: 1.74–12.7]). The present study indicates a postive linear association between oral health and mortality

Complete Momentum Balance in Ionization of H₂ by 75-keV-Proton Impact for Varying Projectile Coherence

We report on a kinematically complete experiment on ionization of H2 by proton impact. While a significant impact of the projectile coherence properties on the scattering-angle dependence of double-differential cross sections (DDCSs), reported earlier, is confirmed by the present data, only weak coherence effects are found in the electron and recoil-ion momentum dependence of the DDCSs. This suggests that the phase angle in the interference term is determined primarily by the projectile momentum transfer rather than by the recoil-ion momentum. We therefore cannot rule out the possibility that the interference observed in our data is not primarily due to a two-center effect

Fully Differential Study of Interference Effects in the Ionization of H₂ by Proton Impact

We have measured fully differential cross sections for ionization of H2 by 75-keV proton impact. The coherence length of the projectile beam was varied by changing the distance between a collimating slit and the target. By comparing the cross sections measured for large and small coherence lengths pronounced interference effects could be identified in the data. A surprising result is that the phase angle in the interference term is primarily determined by the momentum transfer and only to a lesser extent by the recoil-ion momentum
