Due to misconceptions surrounding radiation and nuclear energy, educating the general public about basic radiation concepts has become increasingly important. The Virtual Education and Research Laboratory (VERL) at the University of Illinois at Urbana-Champaign (UIUC) has developed a 3D, virtual, interactive game that conveys the physics of radiation and principles of radiation protection to the player. The model is a scavenger hunt style game that takes place in a virtual model of a TRIGA research reactor. Several virtual radiation sources are placed in the 3D virtual model of the TRIGA facility. Radiation drops away from the radiation source. The effect of shielding can also be incorporated in modeling the radiation transport, leading to realistic radiation fields. The user’s goal is to find and collect (virtual) objects placed in this facility while minimizing the dose received in doing so. The player is meant to learn about time, distance, and shielding — key concepts in radiation protection. The start screen displays the radiation field in the form of a colored coded floor, as well as the location of the desired objects. With the given information, the player is encouraged to plan the route to collect the items and minimize exposure. By repeatedly playing the game, the player becomes familiar with the layout of the facility, and of the location of the radiation sources. This educational game is a useful teaching tool. Those unfamiliar with radiation protection concepts are able to understand how important time, distance, and shielding are in minimizing dosage. Additionally, this game proves to be a useful engagement and outreach tool. Upon completion of the game, the user is shown the score, the dose received, as well as a list of dose received in well-known instances such as eating a banana or in getting an x-ray at the dentist’s office. The dose minimization game developed earlier for computers has now been developed for use as a game-app for cell phones. These recent developments allow for wider outreach, further increasing the use of the model as an outreach and educational tool.

This paper describes the reduction in memory and computational time for the simulation of complex radiation transport problems with the discrete ordinate method (DOM) model in the open-source computational fluid dynamics platform OpenFOAM. Finite volume models require storage of vector variables in each spatial cell; DOM introduces two additional discretizations, in direction and wavelength, making memory a limiting factor. Using specific classes for radiation sources data, changing the store of fluxes and other minor changes allowed a reduction of 75% in memory requirements. Besides, a hierarchical parallelization was developed, where each node of the standard parallelization uses several computing threads, allowing higher speed and scalability of the problem. This architecture, combined with optimization of some parts of the code, allowed a global speedup of x15. This relevant reduction in time and memory of radiation transport opens a new horizon of applications previously unaffordable.

In this chapter, the authors describe the project of a virtual world that they developed in their university and with their students. In this work, they joined concepts like social networks and virtual reality, creating a virtual model of the University Miguel Hernandez (UMH), where students are able to walk around the campus, inside the buildings, chat with other students, and moreover, use videoconferencing rooms where students talk and see other students in the same virtual world. The authors describe this project, called UMHvirtual (available in http://virtual.umh.es), which has been supervised by the authors, implemented by a group of students, and focused on all the university students.

A new world of distance education demands new thinking. Key components to completing the distance educational system requires that institutions determine how the process is designed, delivered, integrated, and supported. Unfortunately, educational administrators tend to view distance education merely as a process of taking existing readings, exercises, handouts, and posting them to the Web. While this approach may seem cost effective, such an approach is not educationally effective. Although the meaningful transition to e-education has just begun, determining measures of effectiveness and efficiency requires innovations in social and political thought beyond the advances in technology. The educational process requires feedback from the professor, from the student, and from the wider community, especially businesses who hire the graduates. As e-learning and higher education reach new heights, they are changing the functions of the university. E-learning changes all the ground rules, including time, distance, and pedagogy. We now have new ways to reach and interact with students, present rich content in courses, and deliver the technologies of the smart classroom to students, wherever they are in the world.

Zusammenfassung Die Zeitschrift Sportwissenschaft (SpW) besteht seit 1971. Als älteste und einzige interdisziplinäre Zeit­schrift für das Fach Sportwissenschaft genießt sie hohe fachliche Reputation. Im letzten Jahr kam es zu einer vorzeitigen Ablösung und Neubesetzung des Herausgeberkollegiums durch die institu­tioneilen Herausgeber Deutscher Olympischer Sportbund (DOSB), Bundesinstitut für Sportwissen­schaft (BISp) und Deutsche Vereinigung für Sportwissenschaft (dvs). Hintergrund war ein Konflikt über die Bewertung von Publikationsleistungen in der Sportwissenschaft im Zusammenhang mit dem Universitäts-Ranking des Centrums für Hochschulentwicklung (CHE). Der Beitrag untersucht die Hintergründe dieses Konflikts, indem zunächst die universitären Rah­menbedingungen dargestellt werden, die die Entwicklung des Faches und der Zeitschrift Sportwis­senschaft begleiteten. Die Geschichte der Zeitschrift bildet einen weiteren Schwerpunkt des Artikels, und schließlich geht es auch um ihre Einordnung in den nationalen und internationalen Markt für sportwissenschaftliche Fachzeitschriften. Am Ende stellt sich die Frage nach der Zukunft eines in­terdisziplinären Konzepts für die Sportwissenschaft.

The University of California has been actively designing a ten meter telescope (TMT) for optical and infrared groundbased astronomical observations since 1977. The project, now developed in considerable detail, is described in a series of Ten Meter Telescope Reports, technical notes, and publications (see, for example, Nelson 1980,1981,1982). In order to achieve an acceptable cost for the project, the design departs substantially from conventional telescope designs. Recognizing that the cost is roughly proportional to the weight of the structure and to the enclosed volume, we have made the reduction of weight and size a high priority goal of the design. To achieve these objectives a light-weight segmented primary mirror was designed. The parabolic primary is a mosaic of 36 hexagonal segments. In addition, the primary focal ratio is f/1.75, thus resulting in a short telescope tube; this allows a very compact dome.
