According To Sir Isaiah Berlin; (a) freedom is an essentially ‘negative’ concept; (b) one's freedom can only be limited deliberately, by another person or persons; (c) the impersonal operation of a natural force, such as gravity, cannot be said to limit freedom; (d) the impersonal operation of a market force cannot be said to limit freedom. I argue that all four claims are false and that (b), (c), and (d) are logically incornsistent with (a). There would be less point to inevitably somewhat ‘picky’ exercise were it not for the fact that Berlin's account of freedom exemplifies a well-entrenched and influential orthodoxy. The fact is made particularly apparent by the prominent role played by assumption (d) in defences of the ‘free market’. I go on to discus this.  相似文献

The purpose of this study was to extend work seeking to improve research definitions of chronic maltreatment by contrasting a definition based on patterns of CPS reports across childhood developmental stages to a previously used definition based upon duration of the period including reports, using teacher-estimated peer relations to represent an extrafamilial outcome domain of social adaptation. The sample includes 387 children who are participating in a multi-site longitudinal study and had been reported for abuse or neglect to CPS between birth and age 8. CPS records from this time period provided the basis of two chronicity constructs: 1) an ordinal categories (OC) definition based upon four Eriksonian stages, and 2) a durational definition (time between first and last reports). Block-wise regression analyses were conducted to examine the relative degree to which the two chronicity definitions contributed to prediction of teacher-estimated peer relations at the age 8 interview. Chronicity characterized with reference to developmental stages significantly predicted troubled peer relations, with child age, sex, and minority status, family income, geographic location, and time of first report taken into account. The effect was pronounced with regard to aggressive peer relations. Duration of maltreatment reports also predicted aggressive peer relations, but significantly less so than did the OC definition. The findings support the view that maltreatment chronicity is usefully defined by taking children’s development into consideration to characterize patterns of maltreatment across developmental stages. Practice and research implications are suggested.  相似文献

In recent years, interest has soared in the development potential of well‐designed cash transfer programs. One particular application is the use of transfers by resource‐rich countries (as recently initiated by Iran) to distribute rents across their populations. An emerging body of research suggests that the development impact of such programs tends to be positive and that, especially when received by poor individuals or households, they can unlock constraints on economic activities, allowing a further increase in income. This paper considers the use of biometric technology to underpin transfer programs and how new technology is opening up possibilities for effective transfer programs that, up to now, have only been a theoretical option in the institutional conditions that prevail in many developing countries. Once implemented, biometric identification systems can be used to support a wide range of other development initiatives including banking, voting, health care, and general identification systems. The paper reviews some of the programs using these technologies and how it is enabling poor countries to leapfrog rich ones in the area of identity, much as the cellphone revolution did in the area of communications.  相似文献
