Most regional health authorities set budgets for fundholding practices according to the amount of care used by the practice population. This article explains why this funding method can only lead to an inequitable allocation of resources between fundholding and non-fundholding practices. Using the experience of North West Thames region, the efforts made to make funding fairer are discussed. The steps that health authorities could take to investigate and reduce the problem are also outlined. In the absence of a capitation formula for funding fundholding practices, the paper suggests that health authorities should do much more to investigate the amount of money they spend on non-fundholding practices. Regions could develop and use other methods to set budgets rather than rely on activity recorded by practices. Regions and the Department of Health should resolve urgently if and how far the budgets for fundholders should be compensated for increases in provider prices. 相似文献

The distribution of surnames for births, marriages and deaths in 1976 among residents of the 12 Local Government Regions of Scotland was analyzed in terms of the coefficient of relationship by isonymy, Ri. Differences between sexes and events for Ri within Regions were consistent with greater inter-Region mobility among males compared with females and among young adults compared with the elderly. There were near zero correlations of geographical distance with Ri between Regions based on all surnames or common surnames. With Ri based on rare surnames, there was a small though statistically nonsignificant negative correlation. The best-fitting two dimensional relationship derived from Ri values based on rare surnames showed a fair correspondence with the map of Scotland, indicating a degree of genetic isolation between the Regions. 相似文献

Summary The effect of model compounds comprising alcohols and paraffins on the radiation sensitivity ofB. pumilus spores has been carried out with the aim of understanding the radiation-induced inactivation of microorganisms when suspended in non-aqueous medium. This study is a prerequisite to the undertaking of radiation sterilization of non-aqueous pharmaceuticals. Spores ofB. pumilus E601 mounted on kaolin powder were suspended in the appropriate organic agent and gamma irradiated under oxic conditions. Spores suspended in paraffins displayed increased radiation response over that for aerated buffered suspensions. Values of inactivation constant ranged between 2× and 5× that for buffer. Less pronounced modification of response was obtained for the alcohols. The results reveal a marked tendency for response to increase with decreasing polarity of the suspending fluid. The partial miscibility of the alcohols in water enabled the examining of the transition from the response characteristic of aerated buffered suspensions to those of the spores in pure organic liquids.This study has been carried out with the aid of a grant from the Joint Committee of the Hebrew University and Hadassah Research Fund 相似文献

For 25 years of observation the morbidity rate of viral hepatitis in the Ukraine was irregular. In individual regions the morbidity level fluctuated within 2 to 3-fold range. Regions with invariably high or low morbidity levels for viral hepatitis were distributed over the territory of the republic not chaotically, but in zones: a zone with invariably high morbidity rate (western), a zone with morbidity rate corresponding to the average level for the republic (south-western), and a zone with an invariably low morbidity rate (north-eastern). The expediency of dividing the territory into epidemiological areas in respect of viral hepatitis on a regional or republican level is discussed. 相似文献

This article traces inequality and numeracy development in the regions of Chile during the 19th and early 20th century. Inequality, measured with anthropometric methods, was associated with a lower speed of human capital formation. Not all talents received the necessary education to make full use of their talent for the regional economy, especially in the south in the early period. However, Chile became slightly less unequal over time and more numerate during the late 19th century. In addition, we study the correlates of low-intensity immigration in Chile. Regions with a relatively high share of North European migrants developed faster in terms of numeracy. 相似文献

The International Union for Conservation of Nature and Natural Resources (IUCN) and the World Wide Fund for Nature (WWF) advocates
an increase of the number of botanical gardens throughout the world as one of the measures that can help to preserve the world's
biodiversity. To implement this strategy, the present work brings forward a suggestion particularly suited to tropical regions:
establishing municipal botanical gardens. It refers to the experience of a newly opened municipal botanical garden in Brazil,
comparing its attractive power on visitors to that of other botanical gardens included in the Brazilian network of Botanical
Gardens. It also presents considerations on in situ conservation in small remnants and on the importance of urban reserves to preserve the regional biodiversity and spread the
conservationist philosophy. The present proposal promotes the participation of local communities making the public opinion
more aware and active, besides being able to counterbalance proposals that support protecting the world biodiversity through
interventionist actions. It assumes that, through actions planned and coordinated by regional and national botanical garden
networks, the measure proposed can mitigate the anthropic actions exerted on important natural reserves all over the world. 相似文献

The geographical extent of exotic plant species is a major component of invasiveness, which has been explained by intrinsic attributes of the plants, such as growth rate, reproductive type, life form, and biogeographical origin. We assessed quantitatively life cycle and biogeographical origin as determinants of the geographical distribution of naturalized plants in continental Chile, using minimum residence time (MRT) as an estimator of introduction date. We assembled a database with information on 428 plants (principally herbs) in continental Chile, corresponding to 61% of the exotic naturalized flora. For each species we recorded: (1) minimum residence time (introduction date or first recorded date in the country); (2) biogeographical origin (American, Eurasian, others); (3) life cycle (annual, perennial, others); (4) number of Chilean regions occupied by the plant. We found that 82 species (19%) have been recorded in only one region of Chile, while only three species have been found in all 13 regions of the country. About 89% of the species (381) have been found only in central Chile (Regions IV to VIII), while the remaining 11% (47) are found only in the northern (Regions I to III) or southern parts of the country (Regions IX to XII). We detected significant differences in regional spread of naturalized plants according to minimum residence time: those species with shorter MRT had more limited spread ranges than those with longer MRT. Biogeographical origin and life cycle did not explain geographical extent in Chile. This study shows that historical factors are more important than biological ones in determining the geographical extent of naturalized plants in continental Chile. Thus, caution should be exercised when assigning value to biological attributes that may confer invasiveness to naturalized plants. 相似文献
