What is the goal of access to health care?

This article first examines the justifications for the goal of access to health care and the variations between health systems in their endorsement of individuals' rights to health care irrespective of income, ethnicity, age and other characteristics. It then examines the meanings of the goal of "access" to health care and considers four key dimensions--service availability ("having" access), service utilisation ("gaining" access), the relevance and effectiveness of services and equity of access. These dimensions provide a common framework that can be applied across countries and health systems and employed to assess the extent to which access to health care is actually achieved.     

The application of lead isotope analysis to bullet individualization in two homicides.

Bullets were characterized by lead isotope ratio analysis and trace element analysis in two homicides. In one case, we concluded that a fatal bullet did not share a common origin with bullets in a box of ammunition containing 24 cartridges taken from suspects. Evidence in the second case included two bullets from the crime scene and 163 bullets taken from various suspects. We were able to infer that the two bullets from the crime scene did not share a common origin and that they differed from all of the bullets taken from suspects. All of the suspects' ammunition had been reloaded as was evident both from trace and isotopic analysis and, indeed, from visual inspection.     

Contributions of Academic Research to Industrial Performance in Five Industry Sectors

Results are presented of a National Academy of Engineering consensus study that documents the contributions of academic research to the growth and competitiveness of five industries – aerospace; financial services; medical devices; network systems and communications; and transportation, distribution, and logistics services. Academic research has made substantial contributions in varying degrees to all five industries. These have ranged from graduates trained in modern research techniques, to fundamental concepts and “key ideas” out of basic and applied research, to the development of tools, prototypes, and marketable products, processes, and services. In network systems, there is a history of university involvement in serving as test beds for new networking concepts and in spawning firms. The academic medical center provides a distinctive environment for testing and incremental improvement of medical devices and for conducting essential clinical trials. In financial services, academic economics and mathematics research contributions have been important, in spite of the lack of a well-developed R&D infrastructure for the industry. Challenges and opportunities for enhancing academic research contributions are presented in the areas of regulatory research and innovation, service sector innovation, information technology, intellectual property rights, and the role and identity of the university.
