AbstractThis contribution focuses on a policy paradox, a failed attempt to introduce a Solar Water Heater bylaw in a South African city in spite of much initial support, both politically and professionally. The paper combines a policy design and a nodal governance perspective to explain why the law failed to materialise. It uses categories developed by the nodal governance approach to characterise the mentalities and technologies of the public agencies involved in the policy process, and explore how distinct policy cultures are nurtured by the networked relations and concomitant learning contexts of these agencies. The analysis shows how the agencies differ sharply on philosophical and practical grounds as to how they typically think about policy values and interventions. This tends to make the collaboration between them difficult as each of them experiences the other as seeking to frustrate rather to assist the policy process. The paper documents how “superstitious learning” became a predominant trait of the bylaw process, as each of the agencies tended to look for evidence in the actions of officials in the other department that confirmed their stereotypical view of them, and reinforced it during the process of interaction. Insufficient attention was given, early on in the bylaw process, to the fact that these departments would have to cooperate closely and that “buy-in” from both was a critical condition for success. Due to this, unfortunate policy design choices fed forward through the implementation process and disabled opportunities for co-learning and collective problem-solving. 相似文献

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the chemical ecology involved in the attraction of the necrophagous hide beetle Dermestes maculatus, which feeds as an adult and larva upon decomposing carcasses. Our aims have been to identify the responsible compounds in the odours of the carcass that are important for the attraction of the beetles. Furthermore, we have studied sex- and age-related differences in beetle attraction and tested whether the hide beetle can distinguish between various stages of decomposition by means of the emitted odours. Headspace collection of volatiles released from piglet carcasses (bloated stage, post-bloating stage, advanced decay and dry remains), coupled gas chromatography-mass spectrometry (GC-MS), gas chromatography with electroantennographic detection (GC-EAD) and bioassays were conducted to identify the volatiles responsible for the attraction of the beetles. Freshly emerged male beetles were attracted by the odour of piglets in the post-bloating stage (9 days after death; T(mean) = 27 °C) and the EAD-active compound benzyl butyrate. Statistical analysis revealed a higher relative proportion of benzyl butyrate in the odour bouquet of the post-bloating stage in comparison with the other stages. We therefore conclude that this compound plays an important role in the attraction of hide beetles to carcass odour. This underlines the potential use of D. maculatus for the estimation of the post mortem interval. The decomposition stage at which the female beetles are attracted to the odour of a cadaver remains unknown, as does the nature of this attraction. Pheromones (sexual or aggregation pheromones) might play an essential role correlated with their attraction to carrion and consequently with their attraction to the substrate for mating and ovipositioning. 相似文献

The purpose of the study was to assess the economic impact of the Denver Broncos Football Club on the Denver Metropolitan Area economy. Primary data required to determine the economic impact was collected from three main sources. First, a two page survey questionnaire was mailed to 9,519 randomly selected season ticket holders with 4,810 returned questionnaires. The City and County of Denver provided financial management information reports for all home games as the second source of primary data. Finally, the Denver Broncos administration provided financial information pertaining to operational expenditures. The total industrial output or economic impact was calculated at $ll7,80l,500 for the economic activity associated with the Denver Broncos Football Club for the 1989-1990 season. Direct economic impact was shown to be $64,282,200 and indirect and induced effects corresponding to the multipliers generated by the model was an additional $53,519,300. Employee compensation was $47,213,300 and property income provided $16,732,000 to the Denver metropolitan economy. Indirect business taxes totaling $7,118,300 went to local, county, state and federal government. The economic activity produced 1,828 jobs directly and indirectly resulting from Broncos activity in the metropolitan area. 相似文献
