I. INTRODUCTION
The earlier orbits and ephemerides for the Soviet satellites were not sufficiently
accurate to be very useful in making observations in Alaska. Extrapolations
from our own observations gave better predictions. This merely pointed out the fact
that rough observations of meridian transits at high latitudes will give better values
of the inclination of the orbit than precision observations at low latitudes. Hence,
it was decided to observe visually the meridian transits estimating the altitude by
noting the position with respect to the stars or using crude alidade measurements.
The times of the earlier observations were observed on a watch or clock and the clock
correction obtained from WWV. Later the times were determined with the aid of stop
watches, taking time intervals from WWV signals.
This rather meager program of optical observations of the Soviet satellites was
undertaken to give supplementary data for use of the radio observations, and particularly
to assist in the prediction of position of the satellite so that the 61-foot
radar of Stanford Research Institute could be set accurately enough to observe it
(the beam width at the half-power points is about 3°).
This report contains primarily the visual observations made at the Geophysical
Institute by various members of the staff, and a series of observations by Olaf
Halverson at Nome, Alaska. In addition there is a short discussion of the geometry
of the trajectory, the illumination of a circumpolar satellite, and a note on the
evaluation of Brouwer's moment factors.Air Force Contract No. AF 30(635)-2887

Experiments with a Model Water Tunnel
This report describes a model water tunnel built in 1928 by the NACA to investigate the possibility of using water tunnels for aerodynamic investigations at large scales. The model tunnel is similar to an open-throat wind tunnel, but uses water for the working fluid
The evaluation of a summer youth scheme for children with disabilities: a brief report on the findings from an evaluation of the Special Needs Advisoryand Activities Project (SNAAP)
Questionnaires were distributed to 7 parents who had children involved in the SNAAP summer youth scheme, along with 7 staff members. Interviews were also carried out with 11 children accessing the SNAAP service. All questionnaires and interviews were developed to provide a detailed evaluation of the SNAAP summer youth scheme. The questionnaires distributed to both parents and staff evaluated the progression of the children and their overall satisfaction with the scheme. The interviews carried out on the children focused on their overall perceptions and satisfaction with SNAAP’s summer youth scheme. The overall aim of the study was to evaluate SNAAP’s existing summer youth scheme and identify any needs or areas of development for the future

Bystander responses to bias-based bullying in schools: a developmental intergroup approach
Research on bystander responses to bullying shows the valuable contribution that prosocial or defending bystander behaviours can have in reducing bullying in schools. We propose that a developmental intergroup approach (i.e., children’s developing understanding of social identities and related intergroup processes) is required to fully understand when and why children and adolescents do or do not help bullied peers in diverse contexts. We first review well-established theory and evidence from intergroup social exclusion literature to demonstrate the strength of a developmental intergroup approach when understanding responses to complex social scenarios across childhood and into adolescence. We then review recent evidence that demonstrates the importance of examining group membership, group identity and group norms to understand children and adolescents’ bystander responses in bias-based bullying contexts. Finally, we consider implications for school-based interventions and next steps for research on bystander responses in childhood and adolescence
Examining the experiences of a short break scheme amongst adolescents with disabilities (service users) and their parents
The present research explored the impact of local short break scheme on the strengths and difficulties of disabled adolescents and their parents. At the end of the scheme disabled children (N=11) took part in semi-structured interviews to evaluate their experiences of the scheme. Data was also collected from their parents (N=7), who completed questionnaires measuring their strengths and difficulties (SDQ, Goodman, 2001) and levels of parental stress (PSI, Abdin, 1995). The findings highlighted that short break schemes can have numerous beneficial effects on disabled adolescent’s health, development and wellbeing. Moreover, the findings suggest that these potential benefits extend beyond the scheme participants to their parents. Finally, areas for future developments emerged, including: funding for more resources, development of young people’s skills, implementing more activities, provide a longer scheme and most significantly the need to develop young adult short break schemes to help aid the transition into adulthood for those from 18 years of age
