The public face of event volunteering at the 2006 Commonwealth Games The media perspective

Volunteers play a major role in mega and major events, both cultural and sporting, contributing invaluable human resources. Frequently described (and, maybe, over-emphasised) as the 'unsung heroes' of such events, relatively little is known about this group of workers when compared with volunteers who give regular and long-term commitment to their area of interest. This paper focuses on media representation and perceptions of volunteering at the 2006 Commonwealth Games in Melbourne. The exploratory study adopts an extended timeframe and reports on media representation of volunteers over the full event cycle from recruitment through training and the actual event, concluding with consideration of the Games' aftermath. The findings highlight various positive and negative aspects of the media representation of volunteering at this type of mega event and how this has the potential to influence its public face. Conclusions focus on the implications for the media management of volunteering at major events and suggestions for future research in this area

Age, Socioeconomic Status and Obesity Growth

The rapid growth in obesity represents a major public concern. Although body weight tends to increase with age, the evolution of obesity over the lifecycle is not well understood. We use longitudinal data from the National Longitudinal Survey of Youth to examine how body weight changes with age for a cohort moving through early adulthood. We further investigate how the age-obesity gradient differs with socioeconomic status (SES) and begin to examine channels for these SES disparities. Our analysis uncovers three main findings. First, weight rises with age but is inversely related to SES at given ages. Second, the SES-obesity gradient widens over the lifecycle, a result consistent with research examining other health outcomes such as overall status or specific medical conditions. Third, a substantial portion of the SES "effect" is transmitted through race/ethnicity and the translation of advantaged family backgrounds during childhood into high levels of subsequent education. Conversely, little of the SES difference appears to be propagated through family income, marital status, number of children, or the set of health behaviors we control for. However, approximately half of the SES-weight correlation persists after the inclusion of controls, illustrating the need for further study of mechanisms for the gradient.

Asteroid observations and planetary atmospheres analysis

Photoelectric observations of Eros and 30 other asteroids providing information on their surface characteristics, shape, and rotation axes are reported. Photographs of 18 asteroids and 4 comets yielding accurate position information on various dates were obtained. Photometric observations were made of the Saturn satellite lapetus, and electronographic images of the Uranus and Neptune satellites were obtained experimentally with a Spectracon tube to assess photometry by that method. Planetary patrol photographs of Venus and deconvolved area scans of Uranus were taken. UBV photometry of the Galilean satellites for the period 1973-1974 was completely analyzed and accepted for publication. An improved magnitude and color index for Minas were derived from 1974 area scans. A special photomultiplier tube with a suppressor grid was incorporated into a pulse-counting photometer with special added circuitry for carrying out the observations concerning the constancy of solar system dimensions over cosmic time

Studies in planetology, including the collection and interpretation of planetary information

The value of synoptic imaging of the planets is reported. The advantage of the Large Space Telescope, as compared with ground-based telescopes and planetary orbiters and flybys, is discussed. Desirable LST camera parameters and observing strategies are considered from the standpoint of synoptic imaging

Planetary Research Center

Extensive Earth-based photography of Mars, Jupiter, and Venus is presented which monitors the atmospheric and/or surface changes that take place day to day. Color pictures are included of the 1973 dust storm on Mars, showing the daily cycle of the storm's regeneration. Martian topography, and the progress of the storm is examined. Areas most affected by the storm are summarized

Volunteers and volunteering in leisure : social science perspectives

Leisure has been widely examined within the context of social science theory; however, little work has considered the range of social science disciplines and applied them to specific phenomena located within the leisure field. This paper adopts such an approach to conceptualise and examine volunteers and volunteering in leisure settings. In a disciplinary sense, therefore, the sociological view focuses upon the conceptualisation of volunteering as leisure, the psychological view seeks to understand motivations driving volunteering while the perspective of economists tends to complement these standpoints in terms of why people volunteer and further examines the value of volunteer contributions. Comparative analysis of the perspectives enunciated within these key disciplines provides a picture of the status of research relating to leisure volunteers and volunteering. The purposes of this paper are to identify gaps in current knowledge, drawing out conclusions and their implications for an improved understanding of this area as well as to enhance comprehension of disciplinary contributions to the study of leisure phenomena

Post-mission Viking data anaysis

Three Mars data analysis projects from the Viking Mars program were identified initially, and three more came into being as the work proceeded. All together, these six pertained to: (1) the veritical distribution of scattering particles in the Martian atmosphere at various locations in various seasons, (2) the physical parameters that define photometric properties of the Martian surface and atmosphere, (3) patterns of dust-cloud and global dust-storm development, (4) a direct comparison of near-simultaneous Viking and ground-based observations, (5) the annual formation and dissipation of polar frost caps, and (6) evidence concerning possible present-day volcanism or venting. A list of publications pertaining to the appropriate projects is included
