  • Water supports life, society, the environment and the economy, therefore, the task of ensuring a nation's water supply is one of the most fundamental responsibilities of every government. Water management has become a greater challenge due to the increased demand for water as a result of population growth and the impact of climate change on the variability of rainfall. In response, many cities have implemented plans to augment their traditional water supplies (e.g. dams and groundwater) with new or alternative sources (e.g. recycled wastewater and desalinated sea water). Historical evidence suggests that in order for water augmentation projects to be successfully implemented, the support of the general public is required. It is thus critical to understand the factors which influence people's attitudes regarding water‐related matters. The aim of this study is to identify these influencing factors. Results from an empirical study including both qualitative and quantitative components indicate that a number of factors are influential in the public's acceptance of alternative water sources, including research findings, the experience of water shortage, consideration for future generations and news, facts and other publicized information. Notably, politicians and the government were rated by respondents as having a low level of influence. Factors which may determine differences in influence were explored. This revealed a small number of differences for people with low acceptance levels of recycled and desalinated water, and for people with higher levels of education. Systematic differences were identified by comparing the general Australian population with that of Toowoomba, a regional town in Queensland where a referendum on a water recycling project was held. Policy implications are discussed.

The article presents a comparative analysis of the strategies applied by Danish and Norwegian patient organisations and organisations for disabled persons in order to promote the interests of their members. Three research questions are addressed: Are Danish and Norwegian patient organisations service organisations operating according to a ‘logic of membership’ or political pressure groups acting according to a ‘logic of influence’? Do patient organisations apply ‘insider’ or ‘outsider’ strategies in their efforts to influence healthcare policies? What impact do different authority structures have on the patient organisations' influencing strategies? The latter question is related to recent reforms in the public healthcare systems of the two countries. The major responsibility for public hospitals now rests with regional authorities in Denmark and central government in Norway. The study is based on a survey among nationwide patient organisations in the two countries and shows that most patient groups are ‘polyvalent’‘venue shoppers’ combining a variety of influencing strategies.  相似文献

This article explores the political and economic forces involved in the development of privatization policies within the health care sector in Thailand. It is suggested that many of the motivating factors behind private sector growth are outside of the health sector; the general macroeconomic environment and tax incentives have stimulated private sector expansion. Within the Ministry of Public Health a preoccupation with improving care in rural areas and an unclear policy line on the private sector has facilitated this expansion. Only recently has private sector growth come to the policy agenda. During this lag period a number of interest groups have developed. It will be difficult to overcome these entrenched interests in order to change policy direction. Meanwhile, problems of rapid cost inflation and inequity face the Thai health care system. Although this case study focuses upon the health care sector in Thailand it would appear relevant both to other sectors and to other countries. The relationship between development models based upon pro-private, pro-market tenets and the establishment of a satisfactory social policy is questioned.  相似文献

The estimation of time since the latest discharge of rifles has been achieved by the SPME sampling technique and the GC-TEA analytical system. An unidentified compound, designated as the TEA2 compound, was detected in all the rifles investigated. The same compound was observed in shotguns and spent cartridges in our previous work. This compound escapes rapidly from the inside of rifle barrels, but can still be detected there one to two months after the shooting. The decrease of the TEA2 peak with time after shooting is non-exponential, and the curve-fitting procedure proposed for the estimation of time since discharge of shotguns can be applied also for rifles.  相似文献
