Current ideas about the role of the state include an enthusiasm for mechanisms of "indirect" or "third-party" governance. The health care arena, in which models of indirect governance have a long history, is an important test bed for these ideas. Classically, the arena was marked by trust-based, principal-agent relationships established to overcome information gaps. Over time (and to different degrees across nations), emphasis shifted to contractual relationships assuming relatively well-informed actors and then to performance monitoring and information sharing within complex and loosely coupled networks. In this latest stage, there is a risk that some important features of democratic leadership, and of decision making in the health care arena, will be eclipsed. Accountability mechanisms must clearly locate responsibility for actions and must allow for the exercise of professional judgment.  相似文献

The Guiding Principles on Business and Human Rights (UNGPs) were endorsed by the United Nations Human Rights Council in June 2011, following the six‐year mandate of the Special Representative to the Secretary General (SRSG) on the issue of human rights and transnational corporations and other business enterprises. The SRSG developed a framework comprised of three pillars: (1) States have a duty to protect against human rights abuses committed by third parties, including business enterprises; (2) business enterprises have a responsibility to respect human rights; and (3) victims of business‐related human rights abuses need access to effective remedies. In particular, guiding principle (GP) 11 provides that business enterprises should respect human rights, that is, they should avoid infringing on the human rights of others and address adverse human rights impacts with which they are involved. This article considers the implications of the Guiding Principles' framework for business; the continuing role of conventional accountability mechanisms in providing access to remedy for victims under the third pillar of the framework; and developments in ‘hard law', with a particular focus on the approach by the UK, since the introduction of the UNGPs, before turning, briefly, to the future for business and human rights.  相似文献

A series of experiments were conducted using various types of pollen grain, powder and metal particulates to determine their persistence on a range of different types of materials. The decay curves generated in the repeated experiments all broadly conform to those obtained and already presented in the literature for fibres and glass particulates. The experiments presented in this paper were conducted for up to 647 hours for individual runs and it was found that a general rule existed that it was the material type rather than the particulate type that was the major controlling factor in the persistence of particles. For the pollen grain experiments the overall theory is sustained; there is a significant loss initially followed by a slower decay although this is not precise given the varied nature of palynomorph types. The manner by which the particulates were introduced onto the material had an initial immediate effect, however, the persistence of these particulates over longer periods of time was generally unaffected.  相似文献
