The article argues for the importance of reconciling the institutions of representative government and network governance by means of a combined structure of 'co-governance', and the need for elected politicians in a role as co-governing guardians of democracy in network governance. Based on an examination of two different cases of interactive governance within the field of school reform at the local level in Denmark, some lessons are drawn as to an appropriate new role for elected politicians in a structure of co-governance. 相似文献

Families that adopt children who are in foster care may receive monthly adoption assistance payments to offset the cost of raising the adopted child. The amount of the adoption assistance payment is the subject of bargaining between the family and the child welfare authority. This article uses a bargaining model to highlight factors that, in addition to the expected costs of raising the child, might influence the outcome of bargaining over adoption assistance payments. Findings indicate that married parents who adopt children already in their care have an advantage in bargaining, and single women who adopt their kin or foster children have a disadvantage in bargaining. 相似文献

This presentation looks beyond the contemporary controversy over the use of race in drug courier profiling and examines the
broad spectrum of rare relations affecting police operations. Racial controversy is not new to law enforcement, nor is it
a recent phenomenon in American society. American police do not get enough credit for the enormous amount of positive daily
interaction within minority communities. Police are pervasively present within minority communities around the clock successfully
solving disputes, responding to calls for service, and addressing community concerns. It is against this backdrop that many
in law enforcement are becoming increasingly frustrated by the perception, if not the reality of deteriorating race relations
between police and minorities. One thing is certain: police cannot withdraw from racial conflict. Police will continue to
operate within minority communities, regardless of the racial composition of either the community or the law enforcement agency.
Therefore, officer and supervisory training should not only focus on how to avoid racial conflict, but also on how to ethically
and legally perform in an environment where treatment of minorities is critically examined. 相似文献

The EC Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) came into force on 1 June 2007, marking the end of three years of intense negotiations between the Council and the European Parliament. One of the most hotly debated topics was the registration of substances, where the original Commission proposal sparked an extensive debate about the volume-based structure proposed. Risk-based prioritization was a concept proposed by both industry and academia to replace this, but due to its own fundamental lack of workability, its inclusion was rejected. However, a lightening of the low tonnage levels was agreed, along with the practical implementation of the 'one substance, one registration' principle. Overall, it can be seen that despite the many changes proposed, analyzed, discussed and accepted during the three years of intense negotiations, the basic architecture that the Commission proposed remains and registration will provide an enforceable framework for companies and will ensure a level playing field for chemicals across Europe. 相似文献

ABSTRACTDoes the introduction of UN forces impact terrorism? We argue that at least initially, UN peacekeeping missions may significantly shift the local conflict bargaining process, creating incentives for terrorist and insurgent groups to increase their attacks against civilians. UN missions create a symbolic endpoint to initial negotiations, alter the balance of power between combatants, and may change the relationship between local combatants and the civilian population they rely on for support. We test this argument using monthly data from 12 African countries, analyzing the risk of terrorism at the local level. We find that the introduction of UN forces in an area significantly increases the short-term risk of terrorism, but longer missions in the country reduce this risk. 相似文献

This paper proposes a new approach for automatic classification of counterfeit Viagra(?) and Cialis(?) tablets using image processing and statistical analysis. A high resolution VSC 5000 is used for image acquisition in a controlled environment, and the combination of a thresholding technique with morphological operators is used to segment the tablet from the background. A statistical model based on the RGB color components of original samples is built, and the detection of counterfeit tablets was performed by checking the adherence of a test sample to the obtained distribution using the Bhattacharyya distance. Our experimental results indicated that counterfeit tablets can be effective detected using the proposed approach. 相似文献
