In 1985 North Carolina's Local Government Commission (LGC) began a program to evaluate the percentage portfolios of the funds invested and the diversity of the investment governments and public authorities. The LGC established state's local five evaluation criteria and notified the governments and authorities of deviations from the five investment norms. This article discusses what was reported to the LGC and changes in invested funds occuring after LGC's evaluation. Principal findings include: cities over 10,000 population and counties in general are investing a high percentage of their funds; small-sized cities and public authorities tend to avoid the higher yielding, but more complex to purchase, instruments: and most governments and authorities experienced a considerable increase in the percentage of funds invested after review by the LGC. Based on the marked increases in funds invested, other states should consider helping local governments and public authorities with cash management.  相似文献

This paper focuses on the impact that state sunset review has had on the real estate occupation's ability to restrict entry through the imposition of licensing requirements. The results presented indicate that the 1983 rejection rate for real estate brokers and salespersons was lower in states undergoing sunset review of real estate than in those states not undergoing such a review. Sunset appears to have the power to effect changes in the licensing behavior of the occupation considered in this analysis.  相似文献

The transfer of technology to the Third World is often accompanied by a mystique that inhibits the solution of problems faced by the rural poor. An important innovation in medical technology-the so-called ‘Jaipur foot’–illustrates what can be done in the way of rehabilitation work that uses culturally suitable technology and local craftsmen. The experiment required a special mix of organizational and technological inputs. Innovative design was combined with the mobilization of indigenous craftsmanship and the involvement of a voluntary organization. Community support has strengthened the acceptability of technology. Relations between medical personnel and craftsmen benefited the contribution made by both sides. The advantage of local craftsmen over trained limb-makers became apparent. The voluntary body helped the project to avoid bureaucratic obstacles. The very success of the project, however, has produced its own problems, and crucial decisions have to be made about the future of this kind of strategy for a more appropriate technology.  相似文献

This article describes a nationwide empirical study that will be undertaken during the next three years into the newly emerging phenomenon of genetic discrimination. In particular, the study aims to investigate the nature and extent of genetic discrimination in Australia across three key perspectives: consumers, third parties and the legal system. Further, the study aims to examine the social and legal implications of genetic discrimination, with a view to making recommendations for use in the Australian legal and policy context. It is anticipated that the data produced from this multifaceted investigation will assist in identifying areas where legal or other reforms are required. It will contribute significant baseline data for facilitating ongoing assessment of the nature and extent of the problem, as well as for longitudinal evaluation of the impact and effectiveness of any reforms which may be introduced in the future to address the issue.  相似文献

Since the concept of "brain death" was introduced in medical terminology, enough evidence has come to light to show that the concept is based on an unclear and incoherent theory. The "brain death" concept suffers by internal inconsistencies in both the tests-criterion and the criterion-definition relationships. It is also evident that there are residual vegetative functions in "brain dead" patients. Since the content of consciousness is inaccessible in these patients who are in a profound coma, the diagnosis of "brain death" is based on an unproved hypothesis. A critical evaluation of the role and the limitations of the confirmatory tests in the diagnosis of "brain death" is attempted. Finally it is pointed out that a holistic approach to the problem of "brain death" in humans should necessarily include the inspection of the content of consciousness.  相似文献

A simple technique is presented for the longitudinal sectioning of hair samples without the need for any embedding medium. The technique applies to single hair samples that are placed in a groove of a particular depth and can either be scraped or cut to the desired level. Planar sections are obtained that reveal the internal structure of the sample and are ideal for the application of surface analytical techniques for the study of internal transverse and longitudinal distributions of xenobiotics.  相似文献
