چکیده
Methods The data sources and methods of estimation used in this study are the same as those used for the 1988 calculations. Birth data were taken from publications of the NCHS,5 which obtains birth certificate information from state vital statistics agencies. The most recent NCHS data tabulate race according to the race of the mother rather than the child, and the NCHS has retabulated data from the 1980s in the same way; consequently, the birthrates presented here for the 1980s by race differ from those published previously. Racial groups other than white and black are not shown separately because of small numbers and the heterogeneity of this population. Hispanics may be of any race, and the figures for whites include the large majority of Hispanics. Surveys conducted by The Alan Guttmacher Institute (AGI) of all known abortion providers in the country were the source for the annual number of abortions.6 Information from the surveys was available for 1980–1982, 1984–1985, 1987–1988 and 1991–1992; data for other Stanley K. Henshaw is deputy director of research, The Alan Guttmacher Institute, New York. The research on which this article is based was funded in large part by The Prospect Hill Foundation.

متن کاملAutomated Landscape Painting in the Style of Bob Ross
Research in non-photorealistic rendering often focuses on reproducing specific artistic styles. Unfortunately, many artists are unwilling or unable to articulate the technical basis of their style. Bob Ross is a notable exception. He left behind a complete and explicit record, in print and on video. His paintings cut many corners in the representation of reality, but they are convincing. Bob Ro...
متن کاملGPU-based Visualisation of Protein Secondary Structure
The increasing number of protein 3D structure information available makes the high-quality visualisation of this information play a more and more important role. Beside element-based representations the secondary-structurebased representation – also called cartoon representation – refers to a higher level of abstraction, representing the protein structure as tubes and ribbons. We present a meth...
متن کاملComputer Graphics Education and the understanding of pixel plotting algorithms using Growth Aggregation models
It is sometimes difficult to teach fundamental aspects of computer graphics, especially pixel plotting techniques, as some students fail to engage with the material. In this paper we describe a constructionist approach to help students learn about fundamental computer graphics techniques. By getting the students to develop code that performs a growth aggregation model, principally using Diffusi...
