The correlation between jump height and mechanical power in a countermovement jump is artificially inflated

ABSTRACT The countermovement jump is commonly used to assess an athlete’s neuromuscular capacity. The aim of this study was to identify the mechanism behind the strong correlation between jump height and mechanical power in a countermovement jump. Three athletes each performed between 47 and 60 maximal-effort countermovement jumps on a force platform. For all three athletes, peak mechanical power and average mechanical power were strongly correlated with jump height (r = 0.54–0.90). The correlation between jump height and peak power was largely determined by the correlation between jump height and the velocity at peak power (r = 0.83–0.94) and was not related to the correlation between jump height and the ground reaction force at peak power (r = −0.20–0.18). These results confirm that the strong correlation between jump height and power is an artefact arising from how power is calculated. Power is a compound variable calculated from the product of instantaneous ground reaction force and instantaneous velocity, and application of statistical theory shows that the correlation between jump height and power is artificially inflated by the near-perfect correlation between jump height and the velocity at peak power. Despite this finding, mechanical power might still be useful in assessing the neuromuscular capacity of an athlete.

Health Status of Gasoline Station Workers in Pathumwan Area, Bangkok, Thailand, in 2004 and 2009

This research characterized and compared health status of male gasoline station workers in Pathumwan District, Bangkok, in 2004 and 2009. Between these years, use of methyl tert-butyl ether (MTBE) in gasoline was banned in Thailand, and use of gasohol increased. Cross-sectional studies were conducted in each year. Each study included an interview for symptom prevalences, hematological tests and blood biochemical tests for kidney and liver function. Data were analyzed with multiple logistic regression for dichotomous outcomes and multiple linear regression for continuous outcomes. Independent variables included year of study, demographic characteristics, smoking, alcohol drinking, and duration of working at the gas station. Adjusted prevalence of abnormal red blood cell morphology decreased statistically significantly from 2004 to 2009 (modeled odds ratio for 2009 vs. 2004 = 0,34, p=0.04 ). Adjusted blood alkaline phosphatase level also decreased significantly (modeled decrease = -29.3 units/liter, p<0.001 ). These findings could plausibly be linked to removal of MTBE. Other health-related metrics did not differ significantly between 2004 and 2009. On balance, there was a limited tendency toward improvement of workers' health from 2004 to 2009. This could be attributable in part to removal of MTBE in gasoline. Further research, perhaps employing additional health metrics, is needed to fully characterize human health effects of MTBE exposure.
A Planar Millimeter-Wave Antenna Array With a Pillbox-Distributed Network

This article introduces a new structure of radiating element for developing a wideband planar antenna array for millimeter-wave applications. The proposed radiating element consists of a slot-coupled magnetoelectric (ME) dipole and two microstrip patches, which produce the merits in bandwidth and gain enhancements for the antenna. The unique structure of the radiating element is an excellent candidate for building up an antenna array in millimeter-wave frequencies. To design the millimeter-wave antenna array with a low complexity in the power-distributed network, a stacked pillbox power divider is used to deliver equal-phase power distributions to all array elements. To provide sufficient bandwidth for the antenna array, an improved transition structured by a rectangular waveguide (WR) and a differential substrate-integrated waveguide (SIW) is adopted. To verify our proposed design, a prototype of the antenna array is examined and measured. The array obtains an impedance bandwidth of 30.7%, covering the frequency range from 53 to 72 GHz. Stable radiation patterns are found with the 3 dB gain bandwidth of 25.4% and the maximum gain of 25.1 dBi. This proposed antenna array can be employed to potential applications in millimeter-wave communication systems.
The Pre-He White Dwarf in the Post-mass Transfer Binary EL CVn

EL CVn is the prototype of a class of eclipsing binaries that consist of an A- or F-type main-sequence star and a hot, low-mass, pre-He white dwarf (pre-He WD), the stripped down remains of the former mass donor. Here we present the first direct detection and characterization of the spectrum of the pre-He WD in EL CVn that was made possible through far-UV spectroscopy with the Hubble Space Telescope Cosmic Origins Spectrograph. These spectra straddle the wavelength range where flux dominance shifts from the pre-He WD to the A star. Radial velocities of both components were measured from the far-UV spectra and new optical spectra from the Apache Point Observatory Astrophysical Research Consortium Echelle Spectrograph. We also obtained fast cadence photometry of the eclipses with the pt5m telescope at the Roque de los Muchachos Observatory. A combined analysis of the velocities and light curve yields the component masses and radii. We applied a Doppler tomography algorithm to reconstruct the individual spectra, and we compared these to models to estimate the effective temperatures. The pre-He WD has low mass (0.176 ± 0.004 M⊙), is small (0.284 ± 0.003 R⊙), and is relatively hot (11,800 ± 400 K), and these parameters are approximately consistent with predictions for a star stripped through stable mass transfer. The spectral lines of the pre-He WD show that its atmosphere is H-rich, He-depleted, and metal-poor, probably as the result of elemental diffusion that has occurred since mass transfer ceased.

Chronic Total Occlusion (CTO): Scientific Benefit and Principal Interventional Approach

Chronic total occlusion (CTO) of coronary arteries are found in about 20% of patients undergoing percutaneous coronary intervention (PCI) and in about 50% of post-CABG patients. Specialized centers can now achieve success rates of over 85%, which is a result of technical advancements in retrograde techniques irrespective of the CTO anatomy. Due to the complexity of retrograde CTO-techniques, a consensus paper issued by the EuroCTO- Club requires interventional cardiologists to have sufficient experience in antegrade approaches (>300 antegrade CTO-cases, 50/year) with additional retrograde training (25 retrograde cases each as first and second operator) before becoming an independent retrograde operator. The increased investment in time and technical resources may only be justified if the patient has a clear clinical benefit. However, technical advancements and the clearer evidence that complete revascularization can be achieved in patients with coronary multivessel disease have attracted growing interest in recent years from inter ventional cardiologists in treating CTO. The chapter will review current knowledge in the interventional treatment of CTO and focuses on indications and the potential benefits for the individual patient being based on the current state of scientific evidence.
A Profitable Education

In this chapter, the authors take a multifaceted critical approach to understanding and deconstructing the term 21st century skills, especially in regard to technology and the role of corporations in the discourses about education. They also consider a range of cultural and political influences in our exploration of the social and academic meanings of the term, including its history and politics. The application of the term in present-day educational contexts is considered as well as possible futures implied through the term. The goal in this chapter is to counter ideas that might diminish a humanized educational practice. Specifically, the authors offer a critique of neoliberal discourses in education, particularly the neoliberal and corporate narrative around 21st century teaching and learning. They raise concerns about what an undue emphasis on industry-oriented educational systems can mean for the core purposes of education.
Abusive Supervisory Behavior Aimed at Raising Work Group Performance

Perceived abusive supervision implies detrimental human consequences and negative performance effects. However, paradoxically, there are numerous anecdotal reports on managers who appear to deliberately mistreat most of their subordinates in an effort to enhance work group performance, preferring abusive methods of influence over more constructive motivational approaches. Because destructive leadership theory does not provide a compelling explanation for this perplexing phenomenon, I conducted an inductive, longitudinal case study at the executive level of a large corporation to explore antecedents of performance-oriented abusive supervisory behavior. The analysis of rich, contextualized data reveals that empathic incompetence of superiors to consider the emotions, goals, and limitations of inferiors can imply a belief in the efficacy of harsh management tactics, resulting in abrasive supervisory conduct and an abusive supervision climate collectively perceived by subalterns. The findings suggest social dominance orientation (SDO) of upper-level managers to moderate these relationships through cognitive activation of abusive supervisory values.

DRY EYE MANAGEMENT IN PATIENTS AFTER CATARACT SURGERY: A LITERATURE REVIEW

Cataract surgery is the most common surgical procedure performed to restore visual function due to opacification of the lens. One of the side effects of cataract surgery is the appearance of dry eye symptoms that can occur one to three weeks after surgery. Dry eye symptoms were reduced visual acuity can affect daily work, so that it can interfere with work productivity and quality of life. This paper is a literature review to identify dry eye management in patients after cataract surgery. The search was carried out on Web of Science, EBSCO, PubMed, and Google Scholar. The results showed that the management of dry eyes can be done with drugs, healthy living behaviors especially maintaining eye health and hygiene and also avoiding various risk factors for dry eyes. Assessment of early signs and symptoms of the dry eye needs to be done before surgery so that it can reduce the risk of dry eye events. Management of dry eye in post-cataract surgery patients needs to be done comprehensively so that it can improve the patient's visual ability and a better quality of life.

MANAGING URBAN SPRAWL USING REMOTE SENSING AND GIS

Abstract. Indian cities, like several other developing cities around the world, are urbanizing at an alarming rate. This unprecedented and uncontrolled urbanization may result in urban sprawl, which is characterized by low-density impervious surfaces, often clumsy, extends along the fringes of metropolitan areas with unbelievable pace, disperse, auto-dependent with environmentally and socially impacting characteristics. The ill-effects of urban sprawl in developing countries scenario is a bit complicated compared to that of developed countries because of uncontrolled population growth and haphazard urbanization. This paper attempts to investigate the capabilities of remote sensing and GIS techniques in understanding the urban sprawl phenomenon in a better way compared to time- consuming conventional methods. An overview of the enormous potential of remote sensing and GIS techniques in mapping and monitoring the Spatio-temporal patterns urban sprawl is dealt with here. The spatial pattern and dynamics of the urban sprawl of Kozhikode Metropolitan Area (KMA, Kerala, India) during the period from 1991 to 2018 using the integrated approach of remote sensing and GIS are attempted here. Index derived Built-up Index (IDBI) which is a thematic index-based index (combination of Normalized Difference Built-up Index (NDBI), Modified Normalized Difference Water Index (MNDWI) and Soil Adjusted Vegetation Index (SAVI)) is used for the rapid and automated extraction of built-up features from the time series satellite imageries. The extracted built-up areas of each year are then used for Shannon’s entropy calculations, which is a method for the quantification of urban sprawl. The results of IDBI and Shannon’s entropy analysis highlight the fact that there occurs an alarming increase in the built-up areal extent from 1991 to 2018. The urban planning authorities can make use of these techniques of built-up area extraction and urban sprawl analysis for effective city planning and sprawl control.
A Time-Segmented Resonant Gate Driver Analysis for Loss, Speed, and SiC Switching Performance Trioptimization

A novel “time-segmented” transient analysis approach is proposed in this article for resonant gate driver (RGD) with triaspect optimization. RGD is a more advanced solution in high-frequency and high-power-density applications than the conventional gate driver (CGD). RGD will achieve lower gate driver loss, faster driving speed, and better SiC switching characteristics. However, the majority of current works on RGD only focused on gate driver loss and ignored its effect on power transistors’ switching behavior. The characteristics of RGD are not well understood and modeled due to the ignorance of nonlinear components, such as power transistor’s nonlinear input capacitor and nonlinear resonant intervals, and driving resistances. All of those result in false estimation of switching time and energy, which will cause underdesign of gate driver power supply and overdesign of resonant inductor. To fully investigate the potential of RGD, a “time-segmented” analysis approach proposed in this article utilizes the second-order equivalent circuit with actual switching transients. Different equivalent input capacitors are adopted for each segment. The impacts of the resonant inductor and gate resistor are studied. An optimized resonant inductor design is summarized by considering the three aspects mentioned earlier. Based on these, a full-bridge series RGD is designed for SiC power transistors. Compared with CGD, RGD can realize a 25% reduction in power consumption and 75.5% faster driving time. The designed RGD also improves SiC’s di/dt and dv/dt up to 32%.
India Ink Staining, a Rapid and Affordable Test for Diagnosis of Cryptococcal Meningitis

Cryptococcal meningitis incidence has increased along with an increase in incidence of HIV-AIDS. This infection causes increased morbidity and mortality in patients with HIV-AIDS. A rapid diagnosis plays an important role to ensure a prompt therapy of the disease. The cryptococcal polysaccharide antigen test for diagnosis of meningitis is rapid but relatively expensive while culture is time consuming. A 47-year man was admitted to hospital with a headache, fever, nausea, and vomiting and a HIV history for the last 6 months. On physical examination, he was compos mentis, meningealâ€™s stimuli signs (+), where as on examination of craniales nerves, motor and sensibility was in a normal range. Routine blood was normal, 60 CD4 cells/mm3. Laboratory finding included a clowdy/turbid Cerebrospinal fluid (CSF), low glucose level (CSF glucose 43 mg / dl vs. blood glucose 293 mg / dl), elevated protein concentration (137.1 mg / dl), and polymorphonuclear pleocytosis. India ink stain showed encapsulated yeasts. Cryptococcus sp is the only encapsulated yeast, while C. neoformans is the most common cause of Cryptococcosis in patients with HIV-AIDS. The patient was diagnosed with Cryptococcal meningitis by indian ink staining, and immediately given anti-fungal theraphy.
Bumblebee worker body size affects new worker production in different resource environments

Behavior and organization of social groups is thought to be vital to the functioning of societies, yet the contributions of various roles within social groups have been difficult to quantify. A common approach to quantifying these role-based contributions is evaluating the performance of individuals at conducting certain roles, these studies ignore how these performances might scale up to effects at the population-level. Manipulative experiments are another common approach to determine population-level effects, but they often ignore potential feedbacks associated with these various roles. Here, we evaluate the effects of worker size distribution in bumblebee colonies on worker production, using functional linear models. Functional linear models are a recent correlative technique that has been used to assess lag effects of environmental drivers on plant performance. We demonstrate potential applications of this technique to explore contributions of social animals to ecological phenomenon. We found that the worker size distribution differentially affected new worker production across three resource environments. Specifically, more larger workers had mostly positive effects and more smaller workers had negative effects on worker production. Most of these effects were only detected under low or fluctuating resource environments suggesting that the advantage of colonies with larger-bodied workers becomes more apparent under stressful conditions. We demonstrate the wider ecological application of functional linear models. We highlight the advantages and limitations when considering these models, and how they are a valuable complement to many of these performance-based and manipulative experiments.
