(Re)constructing career education as a socially just practice: An antipodean reflection

The author contends that career education has lost its way, and needs to be (re)located within a critical social justice framework if it is to effectively prepare young people to engage with the social, political and economic discourses that inform the shaping of ‘career(s)’. Relating to the New Zealand context, differing versions of social justice are outlined, the challenges for career education explored, and the potential for change discussed.     

Experimental study of the critical speed response,of a jeffcott rotor with acceleration

A small, lightly damped rotor (ζ=0.0088) was experimentally tested for a variety of acceleration and deceleration rates. In each case, the amplitude response was plotted as a function of operating speed, with the acceleration rate considered. In each case the results are compared with theoretical predictions. The results agree within 6% at the peak response. The results of the analysis indicate that for high acceleration rates the critical amplitude response may be reduced by a factor of four or more. The frequency of the effective critical speed may be shifted by up to 20%. Furthermore, a beating frequency was observed in the amplitude data after the rotor had passed through the critical speed. This phenomenon is shown to be the vector sum of a synchronous component of amplitude and a nonsynchronous transient component (at the critical speed). The transient nonsynchronous component is shown explicitly via electronic band-pass filtering, as is the forced response component. Finally, spectral analyses were performed over a range of operating speeds, yielding waterfall diagrams and further verification of the existence of the two components.     

THE FUNCTION OF THE HOME

Several months ago, while on a trip East, the editor conversed with a fellow‐traveller about a projected plan for introducing weekday religious education in Ellwood City, Pa. The plan as developed contains several rather interesting features, which may be of value to those planning week‐day instruction in other places. With the consent of Rev. Arthur M. Stevenson, to whose tact and good judgment the successful outcome is largely due, we print his letter giving details.
