Vertical Jump Performance as a Discriminator of Playing Ability in Collegiate Female Soccer Players
Previous studies have assessed the importance of physical characteristics to soccer playing ability by comparing performance-based outcomes between starters and non-starters. Starters are often considered the most skilled players on the team. These players get more playing time than non-starters and have been shown to achieve higher performance outcomes on intermittent fitness tests. However, it remains unclear whether starters can achieve higher performance outcomes on a countermovement vertical jump. PURPOSE: The purpose of this study was to investigate the efficacy of countermovement vertical jump height and peak power to discriminate between starters and non-starters in collegiate female soccer. METHODS: Twenty-seven collegiate female soccer players (age = 19.56 ± 1.28 years; height = 164.26 ± 5.74 cm; body mass = 66.65 ± 8.43 kg) were recruited to participate in the present study. All testing was completed during the 2021 preseason training period. The players were classified as starters (n = 12) or non-starters (n = 15) according to their average number of minutes played per game during the subsequent exhibition season. Each participant reported to the laboratory for a single visit where they performed three countermovement vertical jump tests on a jump mat. For each jump, participants stood on the mat with feet shoulder width apart and hands positioned on the hips. Participants were not allowed to take any steps prior to performing the vertical jump and a quick descending quarter-squat countermovement was allowed before the ascending takeoff phase. The participants were instructed to jump as explosively as possible with both feet at the same time and land on the jump mat in the starting position. Vertical jump height (cm) was estimated from the flight time recorded by the jump mat. Peak power output was estimated using a previously validated regression equation: peak power (W) = 51.9 × vertical jump height (cm) + 48.9 × body mass (kg) - 2007. Independent samples t-tests were used to compare vertical jump height and peak power between the starting and non-starting groups. RESULTS: Vertical jump height was significantly greater (P = 0.039) for the starters (38.60 ± 6.11 cm) compared to the non-starters (34.43 ± 3.75 cm). There was no significant difference (P = 0.448) between the starters (3076.72 ± 331.98 W) and non-starters (3182.23 ± 369.67 W) for peak power. CONCLUSION: These findings suggest that vertical jump height is an effective measure for discriminating between starters and non-starters in collegiate female soccer. Vertical jump characteristics are critical to a player’s performance on the field. Because the starters in this study were able to jump higher than the non-starters, vertical jump height may be an important parameter for identifying players with a high degree of soccer playing ability

Addressing the Disproportionate Representation of Culturally and Linguistically Diverse Students in Special Education
This is the published version, also found here: http://epaa.asu.edu/ojs/article/view/143/269In this article, we present a conceptual framework for addressing the disproportionate representation of culturally and linguistically diverse students in
special education. The cornerstone of our approach to addressing disproportionate
representation is through the creation of culturally responsive educational systems.
Our goal is to assist practitioners, researchers, and policy makers in coalescing around culturally responsive, evidence-based interventions and strategic
improvements in practice and policy to improve students’ educational
opportunities in general education and reduce inappropriate referrals to and
placement in special education. We envision this work as cutting across three
interrelated domains: policies, practices, and people. Policies include those
guidelines enacted at federal, state, district, and school levels that influence
funding, resource allocation, accountability, and other key aspects of schooling. We
use the notion of practice in two ways, in the instrumental sense of daily practices
that all cultural beings engage in to navigate and survive their worlds, and also in a
technical sense to describe the procedures and strategies devised for the purpose of
maximizing students’ learning outcomes. People include all those in the broad
educational system: administrators, teacher educators, teachers, community
members, families, and the children whose opportunities we wish to improve.
Keywords: special education; disproportionate representation; culturally responsive
education; cultural diversity; linguistic diversity
The impact of a 6-week resistance training program with pre- and post-exercise performance supplementation on cardiovascular risk, blood lipids, and fasting blood glucose in resistance trained men
Planetary Candidates Observed by Kepler VI: Planet Sample from Q1-Q16 (47 Months)
\We present the sixth catalog of Kepler candidate planets based on nearly 4
years of high precision photometry. This catalog builds on the legacy of
previous catalogs released by the Kepler project and includes 1493 new Kepler
Objects of Interest (KOIs) of which 554 are planet candidates, and 131 of these
candidates have best fit radii <1.5 R_earth. This brings the total number of
KOIs and planet candidates to 7305 and 4173 respectively. We suspect that many
of these new candidates at the low signal-to-noise limit may be false alarms
created by instrumental noise, and discuss our efforts to identify such
objects. We re-evaluate all previously published KOIs with orbital periods of
>50 days to provide a consistently vetted sample that can be used to improve
planet occurrence rate calculations. We discuss the performance of our planet
detection algorithms, and the consistency of our vetting products. The full
catalog is publicly available at the NASA Exoplanet Archive.Comment: 18 pages, to be published in the Astrophysical Journal Supplement

Heterogeneity of Dengue Illness in Community-Based Prospective Study, Iquitos, Peru
Measuring heterogeneity of dengue illness is necessary to define suitable endpoints in dengue vaccine and therapeutic trials and will help clarify behavioral responses to illness. To quantify heterogeneity in dengue illness, including milder cases, we developed the Dengue Illness Perceptions Response (IPR) survey, which captured detailed symptom data, including intensity, duration, and character, and change in routine activities caused by illness. During 2016–2019, we collected IPR data daily during the acute phase of illness for 79 persons with a positive reverse transcription PCR result for dengue virus RNA. Most participants had mild ambulatory disease. However, we measured substantial heterogeneity in illness experience, symptom duration, and maximum reported intensity of individual symptoms. Symptom intensity was a more valuable predicter of major activity change during dengue illness than symptom presence or absence alone. These data suggest that the IPR measures clinically useful heterogeneity in dengue illness experience and its relation to altered human behavior
