A Study on Professional Athlete Career Transition: an Overview of the Literature Keiko Jodai* and Haruo Nogawa*
Career transitions of professional athletes Review : Sociology and Philosophy A study on professional athlete career transition: an overview of the literature Keiko Jodai* and Haruo Nogawa* *Graduate School,School of Sport and Health Science, Juntendo University 1-1, Hiragagakuendai, Inzai, Chiba, 270-1695 Japan [email protected] [Received February 25, 2011 ; Accepted August 22, 2011] Since the 1990’s, there have been many research studies that focus on career transitions for professional athletes in Japan. The main reason for this is that during that period, amateur sports teams, such as soccer and basketball, were spun off from divisions of companies to become separate professional teams. Consequently, this changed forced how athletes view the transition to a second career because they can no longer count on being employed by the companies that had previously run teams as part of their corporate operations. Research studies primarily covered top athletes but did not distinguish between the amateur and professional athletes. In reviewing the assumptions and results of such previous research with respect to professional status, this study will present the basic themes of such research. For example, early research investigated the actual reasons why and how athletes decide to change career; whereas later research seek to study how athletes speciﬁ cally deal with career changes. Finally, in order to determine the effectiveness of actual support programs, the authors of this study proposes that more thorough investigation is needed to scrutinize how the career transitions of ex-professional football players have changed over time by using a “longitudinal” analysis. Keywords: career transitions, professional athletes [Football Science Vol.9, 50-61, 2012] 1.

The Surrender Software
Scientific image rendering for space scenes with the SurRender software Scientific image rendering for space scenes with the SurRender software R. Brochard, J. Lebreton*, C. Robin, K. Kanani, G. Jonniaux, A. Masson, N. Despré, A. Berjaoui Airbus Defence and Space, 31 rue des Cosmonautes, 31402 Toulouse Cedex, France [email protected] *Corresponding Author Abstract The autonomy of spacecrafts can advantageously be enhanced by vision-based navigation (VBN) techniques. Applications range from manoeuvers around Solar System objects and landing on planetary surfaces, to in -orbit servicing or space debris removal, and even ground imaging. The development and validation of VBN algorithms for space exploration missions relies on the availability of physically accurate relevant images. Yet archival data from past missions can rarely serve this purpose and acquiring new data is often costly. Airbus has developed the image rendering software SurRender, which addresses the specific challenges of realistic image simulation with high level of representativeness for space scenes. In this paper we introduce the software SurRender and how its unique capabilities have proved successful for a variety of applications. Images are rendered by raytracing, which implements the physical principles of geometrical light propagation. Images are rendered in physical units using a macroscopic instrument model and scene objects reflectance functions. It is specially optimized for space scenes, with huge distances between objects and scenes up to Solar System size. Raytracing conveniently tackles some important effects for VBN algorithms: image quality, eclipses, secondary illumination, subpixel limb imaging, etc. From a user standpoint, a simulation is easily setup using the available interfaces (MATLAB/Simulink, Python, and more) by specifying the position of the bodies (Sun, planets, satellites, …) over time, complex 3D shapes and material surface properties, before positioning the camera.

The adventure you and your child are about to embark on will be a very special one. (Yes, it will be your adventure too!) Over the years, we have had the pleasure of watching many children learn, grow, develop, and mature into confident young adults who are ready to face the world. We look forward to the unique opportunities which working with your child will present. This undertaking will give your child a stage on which to develop his confidence, poise, individuality, mental and physical discipline, determination, appreciation for dedicated effort, and self-respect. Your child will mature among individuals and circumstances that will demand his finest efforts and judgments. He will develop close relationships with other young athletes who demand the best of themselves and expect the best in others. Educational opportunities will be made available which will compliment and enhance the experiences he will have in the gym. Above all, he will have tons of fun! We would like to personally congratulate each and every one of you for choosing gymnastics for your child. Gymnastics is the greatest overall body conditioning activity that you can have your child involved in. A study was done testing the components of physical fitness (strength, flexibility, coordination, etc.) of a number of college athletes involved in various sports. When the totals were added up, gymnasts proved to be the most physically fit. Some of the physical attributes that you will find developing in your young gymnast will be: strength, flexibility, kinesthetic awareness, muscular control, muscular endurance, coordination, timing, explosive power, agility, running speed, balance, and grace.

Bolden Testimony
HOLD FOR RELEASE UNTIL PRESENTED BY WITNESS November 17, 2011 Statement of The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration before the Subcommittee on Science and Space Committee on Commerce, Science and Transportation U. S. Senate Mr. Chairman and Members of the Subcommittee, thank you for the opportunity to appear before you today to discuss the outlook for NASA’s human space flight program. This has been a remarkable year, as we have completed assembling and outfitting of the U.S. On-orbit Segment (USOS) of the International Space Station (ISS), allowing us to focus on full utilization of the Station’s research capabilities; taken key steps in moving forward into the future of exploration beyond Low-Earth Orbit (LEO); celebrated the 50 th anniversary of human spaceflight; and witnessed the successful conclusion of the historic Space Shuttle Program. We are also pleased with the progress our industry partners have made in developing an American capability to transport cargo and eventually astronauts to the ISS, and end the outsourcing of this work to foreign governments. More importantly, this will add a critical level of redundancy for transporting cargo and crew to the ISS. A robust transportation architecture is important to ensuring full utilization of this amazing research facility. Enabling commercial crew and cargo transportation systems in LEO allows NASA to focus on developing its own systems for sending astronauts on missions of exploration beyond LEO. This split between commercial and Government systems allows for a cost effective approach to promote a broad base for human exploration by the United States.

1 Practical Rendezvous Scenario For
PRACTICAL RENDEZVOUS SCENARIO FOR TRANSPORTATION MISSIONS TO CIS-LUNAR STATION IN EARTH–MOON L2 HALO ORBIT Naomi Murakami(1), Satoshi Ueda(1), Toshinori Ikenaga(1), Maki Maeda(1), Toru Yamamoto(1), and Hitoshi Ikeda(1) (1)Japan Aerospace Exploration Agency, 2-1-1 Sengen, Tsukuba, Ibaraki, 305-8505, Japan (1)+81-50-3362-3725, [email protected] Abstract: Plans to establish a new international space station in the vicinity of the Moon have drawn attention as a potential gateway for future missions. Assuming that such a station will be constructed, various rendezvous missions will be performed, including logistics flight and crew transportation missions. In the low Earth orbit (LEO), many logistics flight missions have been performed, such as the H-II Transfer Vehicle (HTV) and the Automated Transfer Vehicle (ATV) missions for the International Space Station (ISS), and rendezvous operation technology has been well established. However, in cis-lunar orbits, the dynamics of relative motion are different from those in LEOs, and the GPS- based navigation scheme, which is the key navigation method in LEO rendezvous missions, cannot be applied. Hence, a different type of rendezvous scheme is necessary for application to rendezvous missions in cis-lunar orbits. In this study, we suggest a practical rendezvous scenario for logistics flight missions to the future cis-lunar space station in the Earth–Moon L2 halo orbit and clarify the problems and requirements regarding guidance, navigation, and control (GN&C) for cis-lunar rendezvous. Keywords: Rendezvous, Cis-lunar station, Earth–Moon L2 halo, GN&C. 1. Introduction The updated Global Exploration Roadmap delivered by the International Space Exploration Coordination Group (ISECG) outlines strategies for human and robotic exploration to the Moon, asteroids, and Mars [1].
