State health reform: Effects on labor markets and economic activity

Individual states are actively weighing health care reform proposals and their potential impacts on many levels, including states' own economies. This article considers the effects on state economies of two instruments of health reform: employer mandates and cost containment. The literature suggests that an employer mandate will reduce employees' wages in the long run. In the short run, however, to compensate for the costs associated with mandated health care insurance for their employees, firms may raise their prices to consumers, reduce the number of employees or allow a drop in profit margins. By increasing health care spending and the number of insured persons, mandates would also increase states' levels of economic activity. Though cost containment may dampen the stimulative effects of expanded coverage, resources not spent on health care as a result of effective cost containment might be redistributed to other sectors in a state's economy.     

Agent permeability, principal delegation and the European Court of Human Rights

A growing body of international relations literature examines the delegation of state authority to international organizations. Delegation is a conditional grant of authority from a principal to an agent in which the latter is empowered to act on behalf of the former. This paper explores the effect of agent permeability to interested third parties on the efficacy of control mechanisms established by principals. Our central argument is that higher levels of agent permeability are likely to lead to higher levels of agent autonomy. Because of this, principals who face a potentially permeable agent are likely to delegate more cautiously—partially, in stages, or with clear limits. We illustrate our argument with a case study of the European Convention of Human Rights and its two principal institutions, the Commission and the Court. We find that principals (contracting states) historically delegated quite cautiously to the Court, clearly concerned about the Court’s autonomy. Court behavior in its first two decades reassured principals while increasing the Court’s permeability. Over time, that increased permeability increased Court autonomy in conjunction with the Court’s growing visibility and experience.

The future of urban water services in Latin America

In recent decades, problems with the provision of drinking water and sanitation services around the world have increasingly been addressed by attempts at privatisation, recasting clean water as an essentially economic, rather than public, good. This approach gained particular acceptance in Latin America, but with limited success. In order to address the full range of social, economic and environmental values necessary to sustain water resources over time, public and governmental involvement in establishing integrated water management, pursuing ‘soft path’ approaches, assuring stakeholder input and setting policy will be essential to the process.     

REINVENTING THE PYRAMID

This article describes an orthodox teaching and learning process known as the pyramid. It sets out how this basic process can be used in mediation (and other) training courses. The variations, advantages, and disadvantages of this learning procedure are described. Analogies are drawn between the pyramid method and mediation. Finally, mediators are challenged to add this process and its variations to their repertoires both as trainers and as mediators.     

Public-sector strategy formulation

Abstract: The public sector encounters challenges in strategy formulation and implementation that are distinct from those faced by the private sector, and these include unique cycles of leadership changes, complex internal and external dynamics, and a variety of stakeholders who have diverse definitions of success and failure. To meet the contingencies generated by these factors, public bodies rely on process timelines based on the election cycle, identifying and focusing on key adversaries and supporters, ongoing communications, and utilizing the opportunities presented by real or perceived crises. In adapting to this combination of circumstances, public-sector managers can profitably draw on both deliberate planning methods and emergent strategies.     

Forensic Considerations for Preprocessing Effects on Clinical MDCT Scans

Manipulation of digital photographs destined for medico‐legal inquiry must be thoroughly documented and presented with explanation of any manipulations. Unlike digital photography, computed tomography (CT) data must pass through an additional step before viewing. Reconstruction of raw data involves reconstruction algorithms to preprocess the raw information into display data. Preprocessing of raw data, although it occurs at the source, alters the images and must be accounted for in the same way as postprocessing. Repeated CT scans of a gunshot wound phantom were made using the Toshiba Aquilion 64‐slice multidetector CT scanner. The appearance of fragments, high‐density inclusion artifacts, and soft tissue were assessed. Preprocessing with different algorithms results in substantial differences in image output. It is important to appreciate that preprocessing affects the image, that it does so differently in the presence of high‐density inclusions, and that preprocessing algorithms and scanning parameters may be used to overcome the resulting artifacts.
