Discusses the use of computers for nine different tasks in biological education: information retrieval, data accumulation, data analysis, simulation and systems analysis, decision making, experimental control, course review, computer-managed instruction, and word processing. (PEB)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

This working paper provides suggestions and considerations for anyone contemplating the electronic collection of data on foreign scholars (as distinct from international students). It is noted that, because the Immigration and Naturalization Service requires employment verification and immigration information such as country of citizenship and…

Provides a technological overview of CD-ROM (Compact Disc-Read Only Memory), an optically-based medium for data storage offering large storage capacity, computer-based delivery system, read-only medium, and economic mass production. CD-ROM database attributes appropriate for information delivery are also reviewed, including large database size,…

Discusses data acquisition systems for biologists, considering: (1) input; (2) output; (3) controllers; (4) software for data acquisition; and (5) programing languages. Also discusses several biochemical databases, including those storing data on protein sequences and on chemical structures in two-dimensional form (together with biological testing…

It is not conceivable that in a mixture or compound a component may exist in a negative ratio. Traditionally, therefore, a negative value could not be plotted on triangular coordinates. However, negative values are explicitly allowed, and the results extend the use of triangular coordinates as shown in this article. (JN)

This paper examines the changing demographics of American society and the impact of these changes on higher education. Discussions include a historical background of early American demography, the building and expansion of the population base, and census changes through various generations of the baby boom years and beyond. Next, the report…

This report presents national normative data on the major trends and characteristics of 1.6 million students attending American colleges and universities as first-time, full-time freshmen. The normative data are reported separately for men and for women and for 35 different institutional groupings. Among the findings are the following: (1) student…

This report presents an overview of social and economic census data on African Americans, American Indians, Asians, and Chicanos/Latinos in the seven county metropolitan area of Minneapolis, Minnesota. Among the findings are the following: (1) communities of color made up 9.2 percent of the total metropolitan area population in 1980; (2) poverty…

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

This comprehensive report summarizes the results of the Instructional Locations Away from the Main Campus Survey, Fall 1989. The five tables of data contained in the report are as follows: Table I presents summary information on the 471 instructional locations away from the main campus that were reported; Table II presents detail information by…

This booklet is about document analysis and its utility as a method in education evaluation, and is intended for evaluators in local school districts, regional education agencies, and state departments of education. Document analysis is described as a technique that relies heavily upon a variety of written materials for data, insights, and…

This report provides an overview of the efforts and results of adult basic education centers and classroom teachers and volunteers who provide instruction in the most basic and essential skills for the educationally disadvantaged adults in New York. Charts and graphs illustrate the data that are presented in this photograph-enhanced compilation of…

Presents research results on photosynthetic, carbon monoxide utilizing bacteria. Discusses applications of the research and offers three sets of experimental procedures and data that students analyze to determine which bacterium from a soil sample uses carbon monoxide fastest. (Contains 21 references.) (MDH)
