This paper explores how recent Labour governments have tried systematically to package educational and other social policies for media presentation and public consumption. This concern has resulted in the criticism that Labour is concerned with policy presentation above content: strong on policy spin but weak on policy delivery. The first section explores Labour’s attempts to set a favourable agenda in news media for its educational policies by implementing a rigorous news management strategy: the subsequent section analyses Labour’s unprecedented use of advertising to promote key areas of government policy. There is a particular focus on government advertising in the run up to the 2001 general election. The paper concludes that governments’ increasing reliance on advertising may cross the line which should separate the provision of public information from any attempt to persuade the public to support particular policy choices.  相似文献

Improving educational outcomes for Indigenous Australian students is a key strategy to helping Indigenous people reach their full potential. This has resulted in well-intentioned efforts by Australian educators and governments to ensure Indigenous children have positive school experiences. However, Indigenous students still lag behind their non-Indigenous counterparts in educational outcomes. This is particularly so for Indigenous students living in rural and remote parts of Australia where educational opportunities are limited, especially in high school. One solution to this problem has been to enrol these students in boarding schools in urban and metropolitan centres. While research on the success of boarding schools for Indigenous students is scarce, what little that does exist is not encouraging. The focus of this research was to examine the effects of boarding for Indigenous (= 11) and non-Indigenous students’ (= 158) wellbeing (= 1423) in two large private boys’ schools. Participating students aged 12–18 years old completed a survey measuring wellbeing constructs on two occasions, 12 months apart. Non-Indigenous boys were generally higher in wellbeing compared with Indigenous boys. There was also evidence of improved social wellbeing beyond that of non-Indigenous boarders over time. Overall, while evidence of merit was weak, boarding schools may benefit their Indigenous students’ development in social wellbeing.  相似文献

This study compares the instrumentation and analysis techniques used when determining the power expended pedalling a rope-braked ergometer manufactured by Monark (Sweden) during a low intensity test. Power values were generated by eight subjects. The instrumentation consisted of load cells to measure the rope brake forces, a tachometer to measure the flywheel velocity and instrumented pedal cranks manufactured by Schoberer Rad Messtechnik (SRM). The subjects pedalled a rope-braked ergometer at 60 rev min-1, against a resistance of 3 kg, for 5 minutes. Three different measurements of the mean power were recorded and these were compared with the value given by Monark. The SRM cranks provided two sets of results using different software packages supplied with the cranks. SRM standard software is used for taking measurements during training and cycle races over long time periods. An additional piece of software is provided by SRM called Ptnew, which gives readings of torque and pedal cadence over periods up to 30 seconds. Using the values supplied by Monark each subject generated 180 W of power. The mean power for the eight subjects, measured using the SRM cranks, was 170.36 W (SD 4.11) using the alternative SRM software (Ptnew) over a 30 second period and 173.68 W (SD 2.21) using the standard SRM software. From the direct measurement of the brake forces and flywheel velocity the mean power across the eight subjects was 148.90 W (SD 5.89). The SRM cranks measure the input power, whereas the direct measurement system measures the power output excluding mechanical losses. These values give a figure for the mechanical efficiency for the roped-braked ergometer of 88%. It was found that Monark overestimates the power generated by the subjects when compared with both the SRM systems and the direct measurement instrumentation.  相似文献
