Entering the "land of the "puter braindead"!

My goal has been to give you a basic understanding of the concepts involved with understanding and exploring the web. By this point you should know: what the Internet is, what the World Wide Web is, what a web site is, what a home page is, what a URL is, what a browser is, what hyperlinks are, and how to use your browser to surf the web. Problems that arise can usually be solved by going to the "Help" icon on your browser or going to the Web Tutorials that all browsers have on their software.

Have procompetitive changes altered hospital provision of indigent care?

In the past decade alone there have been numerous changes in the financial and competitive environment of hospitals in the United States. Some examples include the advent of Medicare's Prospective Payment System, growth in managed care options, relaxation of states' Certificate of Need (CON) regulations, and court cases questioning the tax-exempt status of nonprofit hospitals. In this paper we attempt to reveal how hospitals alter their provision of care to the poor in a more cost conscious and competitive environment. Using hospital data from the State of California for the fiscal years ending in 1983 and 1987, estimates explaining uncompensated care commitments are presented. In particular, this study illustrates how hospitals under different ownership control varied their provision of uncompensated care over the period studied on average and by profitability level. Other factors, such as hospital location, teaching status, medicare patient load, and contractual adjustments, are also included in the analysis. A number of interesting trends are detected. Moreover, the results are found to be compatible with a quid pro quo hypothesis which states that hospital regulators reward large uncompensated care providers with profitable CON licenses.

Certificate-of-need deregulation and indigent hospital care.

For almost twenty years certificate-of-need (CON) regulations have protected existing hospitals from unrestricted competition in services. Although the explicit purpose of CON regulation was to prevent hospitals from duplicating services and investing in costly excess capacity, it has been unsuccessful in accomplishing this goal. On the other hand, CON policies have, we suggest, been pursued with the implicit aim of "cross subsidization," that is, regulators have used their power to issue licenses and restrict competition in order to create an incentive to hospitals to provide high levels of care to the indigent population. Posner (1971) has noted that to achieve cross subsidization, entry into lucrative services must be restricted. We present evidence that CON licenses have been used to promote the internal subsidization of indigent care in probit analysis, based on data from Florida spanning the period 1983-89. While this method of financing indigent care may be preferred by legislators who do not want to face the political consequences of raising taxes to pay for the service, it has troubling implications for the hospital provision of indigent care, especially in an era of CON deregulation.

Unpaid hospital bills: evidence from Florida.

Most of what we know about the population generating uncompensated care is inferred from data on the uninsured population. The use of insurance status as an indicator for potential charity patients is justifiable considering the lack of alternative information. This study directly examines uncompensated hospital care using a unique data set generated from a special survey conducted in Florida. A selection model estimated using these data explains who is likely to default on their bill and what amount will be left unpaid. The results provide a clearer picture of the uncompensated hospital care problem.

Relationship among environmental and demographic variables and teacher-rated hyperactivity.

This study assessed the role of environmental and demographic factors in the occurrence of teacher-rated hyperactivity. The subject group consisted of 79 hyperactive and 81 nonhyperactive children ranging from 5 to 12 years of age. Parents of the subjects were interviewed to obtain information regarding the environmental and demographic factors of sex, race, birth order, number of siblings, frequency of change of residence, income level, mother's age, father's age, educational level of mother, educational level of father, parents' marital status, and the method of child discipline used in the home. Comparison between the the hyperactive and nonhyperactive groups suggested nonsignificant differences with the exception of sex (p less than .001), in which the ratio of hyperactive males to hyperactive females was 5:1.
