The Relationship Between Career Variables and Occupational Aspirations and Expectations for Australian High School Adolescents

This study surveyed 925 Australian high school students enrolled in grades 8-12 on measures of occupational aspirations, occupational expectations, career status aspirations and career status expectations, and tested the association between these variables and career maturity, career indecision, career decision-making self-efficacy, and career barriers. Adolescents generally aspired to/expected to work within a small range of RIASEC occupational categories. One third of students reported occupational aspiration/expectation discrepancies. These differed across gender, and across age for females, but not for males. Students who demonstrated both occupational and status aspiration and expectation discrepancies reported more career indecision, were less confident about making a career-related decision, and were less career mature. Students generally held higher occupational status aspirations than expectations, and males were more likely to choose professional occupations than females. Age differences were found for status expectations, but not for status aspirations

The Kolar Gold Fields neutrino project.

In the underground laboratory at a depth of 7 600 ft in the Kolar Gold Mines, South India, five telescopes have been in operation for a study of the cosmic radiation which penetrates to such depths. In an exposure of 677 400 m2 sr h (for isotropic radiation) 46 events have been recorded. In seven events the particle trajectory has a projected zenith angle larger than 50°; these are interpreted as due to muons produced by neutrino interactions in the surrounding rock. From this the rate of neutrino-induced events is estimated to be about 3.1 × 10−13/cm2 s sr.The bulk of events with projected zenith angles less than 40° are interpreted as due to atmospheric muons, from considerations of the expected intensity and angular distribution. In between the above-mentioned two groups, there are 10 events in the zenith angle interval 40°–50° compared with an expected number of events of about two. The difference between the observed and expected rates in this angular interval is discussed.Recently, two new solid-iron magnet spectrographs have been installed at the same level, for measuring the momentum and sign of charge of the muons traversing the detector system. Each spectrograph has a maximum detectable momentum of 20 GeV/c and a collecting power of about 35 m2 sr for isotropic radiation

V. Studies of Cosmic Ray Neutrino Interactions in the Kolar Gold Field Experiment

Results are presented of an experiment to study the penetrating particles in the cosmic radiation deep underground, at a depth of 7500 m.w.e. (standard rock). The events recorded are attributable, in the main, to muons produced either in the atmosphere or by the interactions of neutrinos in the surrounding rock. The muons have been studied in some detail and it appears that the mean energy of the neutrino induced muons (probably less than about 30 GeV) is low compared with that of the muons of atmospheric origin. The significance of the celestial coordinates of the muons and the measured rate of neutrino-induced muons is discussed and the future experimental programme is indicated
