The link between young athletes’ perceptions of their coaches’ behaviors and their own developmental experiences (e.g., opportunities to practice and cultivate personal assets such as leadership, emotion regulation, problem solving, interpersonal skills, etc.) were examined, as well as gender and sport type differences in the reported experiences. Participants were 297 male (41%) and female (59%) junior high and high school student-athletes. All participants completed the Youth Experiences Scale-2 (a measure of positive and negative development experiences), the Coaching Behavior Scale for Sport (a measure of various coaching actions such as mental preparation, positive personal rapport, etc.) and a compilation of items that assessed specific coaching actions targeting the development of life skills (e.g., the degree a coach talked about transferring what is learned in sport to one’s life) for athletes’ primary sport. Linear regression results indicated that several coaching behaviors (e.g., negative rapport and coaching life skills) were significant predictors of the positive and negative developmental experiences assessed. Additionally, a canonical correlation revealed two significant functions, which indicated relationships between perceived coaching behaviors (e.g., positive and negative coaching rapport, helping athletes to develop competition strategies, and coaching life skills behaviors) and athletes’ perceived developmental sport experiences (e.g., identity development, initiative, teamwork and social skills). Finally, gender and sport type differences in athletes’ reported developmental experiences were examined, with significant differences detected between males and females as well as individual and team sport participants and athletes participating in contact, collision and non-/limited-contact sports. Results support previous research by Gould and Carson (2010) and Larsen, Hansen, and Moneta (2006), with the roles of initiative-building as a sport related life skill experience and coach-athlete relationships as key developmental facilitators being emphasized.
WFIRST ULTRA-PRECISE ASTROMETRY II: ASTEROSEISMOLOGY
Andrew Gould,Daniel Huber,Matthew Penny,Dennis Stello 한국천문학회 2015 Journal of The Korean Astronomical Society Vol.48 No.2
WFIRST microlensing observations will return high-precision parallaxes, σ(π) . 0.3 μas, for the roughly 1 million stars with H < 14 in its 2.8 deg2 field toward the Galactic bulge. Combined with its 40,000 epochs of high precision photometry (∼ 0.7 mmag at Hvega = 14 and ∼ 0.1 mmag at H = 8), this will yield a wealth of asteroseismic data of giant stars, primarily in the Galactic bulge but including a substantial fraction of disk stars at all Galactocentric radii interior to the Sun. For brighter stars, the astrometric data will yield an external check on the radii derived from the two asteroseismic parameters, the large-frequency separation hνnli and the frequency of maximum oscillation power νmax, while for the fainter ones, it will enable a mass measurement from the single measurable asteroseismic parameter νmax. Simulations based on Kepler data indicate that WFIRST will be capable of detecting oscillations in stars from slightly less luminous than the red clump to the tip of the red giant branch, yielding roughly 1 million detections.
Euclid ASTEROSEISMOLOGY AND KUIPER BELT OBJECTS
Andrew Gould,Daniel Huber,Dennis Stello 한국천문학회 2016 Journal of The Korean Astronomical Society Vol.49 No.1
Euclid, which is primarily a dark-energy/cosmology mission, may have a microlensing component, consisting of perhaps four dedicated one-month campaigns aimed at the Galactic bulge. We show that such a program would yield excellent auxilliary science, including asteroseismology detections for about 100\,000 giant stars, and detection of about 1000 Kuiper Belt Objects (KBOs), down to 2--2.5 mag below the observed break in the KBO luminosity function at $I\sim 26$. For the 400 KBOs below the break, {\it Euclid} will measure accurate orbits, with fractional period errors $\lesssim 2.5\%$.}
How and Why University Coaches Define, Identify, and Recruit ‘Intangibles’

The purpose of this study was to explore the importance of psychosocial development in competitive university sport. While research in positive youth development (PYD) has increased in recent years, many perspectives have not yet been studied. The mission of PYD is to develop intangible qualities such as learning life skills, developing character, etc(Danish, Forneris, Hodge, & Heke, 2004; Gould & Carson, 2008). There is an implied and some times even an explicit conflict of interests between competitive and developmental sports (Shields & Bredemeier, 2009). In-depth interviews were conducted with 10 Canadian university coaches who were highly trained, experienced, and successful in their respective sports. Results from this study support three conclusions. (a) Coaches described essential intangible attributes such as social character, trustworthiness, maturity, challenging one’s self, being a positive person, toughness/resiliency, motivation, work ethic, and various sport psychology skills. (b) Competitive coaches highly value athletes with life skills, character, and other intangible assets. (c) Coaches have specific strategies for assessing and identifying players with stronger intangibles, as well as for filtering out recruits who severely lack these positive qualities.
SUB-SATURN PLANET MOA-2008-BLG-310Lb: LIKELY TO BE IN THE GALACTIC BULGE
Janczak, Julia,Fukui, A.,Dong, Subo,Monard, L. A. G.,Kozłowski, Szymon,Gould, A.,Beaulieu, J. P.,Kubas, Daniel,Marquette, J. B.,Sumi, T.,Bond, I. A.,Bennett, D. P.,Abe, F.,Furusawa, K.,Hearnshaw, J. B IOP Publishing 2010 The Astrophysical journal Vol.711 No.2
<P>We report the detection of sub-Saturn-mass planet MOA-2008-BLG-310Lb and argue that it is the strongest candidate yet for a bulge planet. Deviations from the single-lens fit are smoothed out by finite-source effects and therefore are not immediately apparent from the light curve. Nevertheless, we find that a model in which the primary has a planetary companion is favored over the single-lens model by Delta chi(2) similar to 880 for an additional 3 degrees of freedom. Detailed analysis yields a planet/star mass ratio q = (3.3 +/- 0.3) x 10(-4) and an angular separation between the planet and star within 10% of the angular Einstein radius. The small angular Einstein radius, theta(E) = 0.155 theta 0.011 mas, constrains the distance to the lens to be D(L) > 6.0 kpc if it is a star (M(L) > 0.08 M(circle dot)). This is the only microlensing exoplanet host discovered so far that must be in the bulge if it is a star. By analyzing VLT NACO adaptive optics images taken near the baseline of the event, we detect additional blended light that is aligned to within 130 mas of the lensed source. This light is plausibly from the lens, but could also be due to a companion to the lens or source, or possibly an unassociated star. If the blended light is indeed due to the lens, we can estimate the mass of the lens, M(L) = 0.67 +/- 0.14 M(circle dot), planet mass m = 74 +/- 17 M(circle plus), and projected separation between the planet and host, 1.25 +/- 0.10 AU, putting it right on the 'snow line.' If not, then the planet has lower mass, is closer to its host and is colder. To distinguish among these possibilities on reasonable timescales would require obtaining Hubble Space Telescope images almost immediately, before the source-lens relative motion of mu = 5 mas yr(-1) causes them to separate substantially.</P>
