It is a recurrent feature of the history of political thought that thinkers have turned their attention to education. Some have been concerned with the reproduction of a political culture through education. Others have sought to redress the failings of present generations by re-educating future citizens. A broad distinction is drawn between 'constructive' political education which takes human nature as given and aims to redirect pupils to new priorities and 'reconstructive' education which tries to effect a transformation of the mind-set and produce new persons. Constructive theories include early utilitarians, conservatives such as Oakeshott and modern democratic realists. Examples of reconstructive theories are communitarians, such as Rousseau and participatory democrats, including J. S. Mill and Dewey. The article concludes with a discussion of attempts, such as that by Rawls, to educate for political neutrality.  相似文献

Lifelong Debt: Rates of Return to Mature Study   总被引:2,自引:0,他引:2  
High rates of return to first degrees have been used to justify increased student financial contributions to higher education. However, no discrete study of rates of return to mature graduates has been carried out although mature graduates now form a significant proportion of the student population. The General Household Survey 1983–1992 was used to examine the earnings of mature graduates compared with those of matriculates. The GHS yielded 616 mature graduate men in full-time work and 296 mature graduate women who were in full-time employment. It was found that the rate of return to mature male graduates was just above one per cent. With recent added costs, new male mature graduates can be forecast to make a sizeable loss on their study. Rates of return to women mature graduates were higher, between five and six per cent, and, based on these figures, the recent increased cost of mature graduate study should be covered by increased earnings. However, these calculations are based on average earnings for the modal age cohort of mature graduates. Those who are older when they complete or earn below the average (a large percentage) will not recoup the costs of study.  相似文献

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes.  相似文献

Equations for the calculation of radiant power F through two apertures in series are well known. A characteristic of these formulae is that they give F as a small difference between two large terms. Evidently, the flux through the apertures must decrease as the spacing between them increases; and for large spacing, the inverse-square relation must hold. Instead of exhibiting this behaviour in an obvious manner, however, the traditional equations give the specious impression of an increase in F with increase in spacing. The paper develops an approximate formulae that applies to apertures in the shape of any regular polygon and that shows clearly how the inverse square relation is approached for large separation.  相似文献

This paper reports on a small-scale study of the social interactions between six children labelled with special educational needs and their peers in their respective early years settings. Data from play observations, photographs and staff interviews is used to examine the dynamics of the connections that they make with other children. The position of these six children as active agents in making decisions about their peer interactions is highlighted and the ways that this agency is expressed is analysed. By focusing on the personal strategies that the children use to make social connections the findings contribute to the developing understanding of children's relationships within inclusive early years settings. In particular compatible play interests and personalities are identified as significant factors that attract children to one another in this case study. It also emerged that recurrent playmates did not feature consistently in the social exchanges involving this group of children. This factor is considered in the context of it being indicative of the social connections that children labelled with special educational needs pursue. Suggestions for further investigation are proposed and key practice messages offered around developing awareness and facilitation of social connections between children.  相似文献

This paper completes our treatment of radiant flux through pairs of apertures. In Part II, we obtained approximate equations for rectangular apertures in parallel planes, with the restriction that two apertures be identical and that one be directly above the other. Here we generalize to the case of any apertures that fit into a rectangular grid. The idea for this generalization originated with Ondracek but it is here expressed in matrix notation, which allows coefficients Fij to be obtained rather simply.  相似文献
