This study presents interview and statistical data from a telephone and fax survey of state agency officials and statistical data from the Centers for Medicare & Medicaid Services' Online Survey Certification and Reporting (OSCAR) system. State survey activities for nursing facilities were reviewed and the number and types of intermediate sanctions issued by states in 1999 were reported, along with barriers to the use of such sanctions. Using five selected enforcement measures to create a summary score, states were classified by quartiles based on the stringency of their nursing facility enforcement activities. Controlling for the number of complaints as a proxy for quality, the predictors of a summary of state enforcement actions were: percentage of population at age eighty-five and above. Democratic governors, higher percentages of chain facilities, and lower facility occupancy rates. Regional differences in enforcement patterns also were shown. Many federal policies and resource constraints were identitied as barriers to effective regulation. The findings identified nursing facility survey and enforcement issues that need to be addressed by policy makers. 相似文献

Several oil paintings, suspected of being stolen, were found in the possession of an art dealer in Tel-Aviv, Israel. The authors were asked to determine if these paintings were the stolen ones, based on photographs, stretchers, and frames submitted by the alleged owners in France. A physical match was found between two of the questioned paintings and two stretchers. Another painting was identified as being previously affixed to the original frame by several nails. The fourth painting was identified as being the one photographed by the alleged owner. This identification was done by comparing micro-topography marks revealed by the illumination conditions of that photograph and of the questioned painting. 相似文献

The Public/Private — The Imagined Boundary in the Imagined Nation/State/Community: The Lebanese case
Suad Joseph 《Feminist Review(on-Line)》1997,55(1):73-89
The article confronts two issues, first the question of women and consumption and second the fashion industry as a feminized sector. In the first instance the argument is that recent scholarship on consumption has been weakened by an inattention to questions of exclusion from consumption and the production of consumption. Income differentials as well as questions of poverty have dropped off the agenda in this debate. Attention instead has been paid to the meaning systems which come into play around items of consumption. This has led to a sense of political complacency as though consumption is not a problem. For the many thousands of women bringing up children at or below the poverty line it clearly is. The second part of the article takes the fashion industry as an example of a field where perspectives on both production and consumption are rarely brought together. This produces a sense of political hopelessness in relation to improving its employment practices, especially for very low paid women workers. The argument here is that greater integration and debate across the production and consumption divide could conceivably result in policies which would make this sector whose employees on a global basis are predominantly female, a better place of work. 相似文献

The acceptance and promotion of partnerships among major countries reflect an attempt on the part of China to re-define its position in the new international strategic pattern. They also reveal a strategic idea offered by China in the post-Cold War era in which it is emerging as a major power. The key questions are as follows. (a) What are the contents of such partnerships among major powers? (b) What are the differences between this partnership model among major powers and the Chinese foreign policy of independence and peace in the 1980s? (c) What are the motivations behind China's promotion of this model of partnerships among major powers? (d) Does the new model of partnerships among the major powers provide an important innovation in the management of relations among the major powers in the coming century? This article attempts to answer these questions so as to better understand China's international strategic behaviour patterns in the post-Cold War era, the inner logic of partnership relationships, and the trends of China's international strategy in the coming century. 相似文献

Recent years have witnessed an intensification of the debate about the fundamental purpose of public assistance to the poor and the effects of these programs on children. This study uses enriched data from the Panel Study of Income Dynamics to examine the effects of living in public housing as a child at some point between 1968 and 1982 on four young adult outcomes: welfare receipt; individual earnings; household earnings relative to the federal poverty line; and employment. Living in public housing during childhood increased employment, raised earnings, and reduced welfare use, but had no effect on household earnings relative to the poverty line. The beneficial effects could have arisen because public housing improved physical living conditions, reduced residential mobility, or enabled families to spend more of their income on items that benefit children's development. Whether these effects apply to contemporary public housing is unknown. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

Various factors governing the detectability of explosive traces after being soaked in water were studied. The variables are: the type of the surface (surfaces liable to be found in aircraft were chosen), the type of explosive, the type of water (tap or seawater), and movement of the immersed surface in the water. The maximal immersion times (tmax) after which explosive detection was possible were evaluated. This datum was found to depend on the type of explosive (one of the important factors is solubility in water), the surface material and the environmental conditions (tap or seawater movement). Detection of PETN on high-density polyethylene, linoleum, glass and aluminum, by the chemical Explosive Testing Kit (ETK), was possible even after a month of soaking in seawater. In addition, it has been found that movement of bulk water around the samples with deposited explosives considerably decreases tmax values. It is, therefore, recommended to retrieve samples for explosive analysis as soon as possible and in areas where the currents of water is minimal. 相似文献

The influence of humidification in the ESDA process on subsequent development of fingerprints on paper items was studied. It was found that, while the DFO process is nearly insensitive to previous humidification, fingerprint development with ninhydrin or with indanedione can be significantly affected by previous humidification of the paper. 相似文献
