Comparison of Approaches to a Multimedia Presentation
Two computer-based multimedia lecture presentations were developed using the same software but using two different approaches. Similar lecture material was used for both lecture presentations. Students found that there were considerable differences between the two lecture presentations. One lecture presentation was found to be very dynamic and interesting compared to the other. However, when videos showing applications of theory were supplied with the less interesting lecture presentation, stude
An Introduction to Plant Vascular Systems
As a laboratory exercise that uses scientific techniques to add an investigative component to study the vascular system of plants.
Developing Customized Instructional Software
Costs to faculty in time and costs for the purchase of software help inhibit widespread instructional computing. mpAuthor is an expensive program for DOS/IBM microcomputers; anyone able to use a word processor producing ASCII files can create menu-driven exercises. Several examples of its use are presented, including some to improve thinking and problem- solving skills. Strengths of the program include: minimal computer skills required (have students create exercises instead of a term paper or a
Control of Surface Exudation by Slugs
This experiment is meant to study water regulation in mollusks by observing the reaction of slugs, which are closely related to mollusks, to excess water.

Crystalluria and its possible significance. A patient-control study.
The significance of crystalluria in the diagnosis and prognosis of urolithiasis remains a controversial subject in the current urological literature. In this study, in addition to the standard urolithiasis clinical and biochemical work-up,routine urine microscopy was performed to study crystals in 1 fresh and 2 stored morning urine samples from 140 urinary stone patients and 42 controls. Crystalluria was more frequently detected in patients (9.3% of the fresh samples)than in controls (2%). Stori

The is the study of how scarce resources are allocated to satisfy unlimited wants in a cultural context. Microeconomics is often defined as the study of individual agents' [persons, organizations, firms, markets] choices about the allocation of scarce goods and how these individual choices relate to the society made up of those individuals. The focus here is the use of technology and social interaction to coordinate individual action.
This collection of activities and resources is a companion guide for the 15-minute film Defying genocide. The history of the Holocaust and the 1994 Rwandan genocide illustrate the entire spectrum of human behavior, from unimaginable evil to extraordinary goodness. Through a study of the Holocaust, Rwanda, and genocide, students learn that genocide occurs because individuals, organizations, and governments make choices to participate, resist, or turn away. Students can also see that at the same

For many years scholars have recognized that late nineteenth-century Durham, North Carolina makes an ideal case study for examining emancipation, industrialization, immigration, and urbanization in the context of the New South. "With its tobacco factories, textile mills, black entrepreneurs, and new college," the historian Syd Nathans observes, "Durham was a hub of enterprise and hope." By the early twentieth century, Durham became renowned for its vibrant entrepreneurial spirit. Both W.E.B. Du
How language works - The cognitive science of linguistics
Students studying linguistics and other language sciences for the first time often have misconceptions about what they are about and what they can offer them. They may think that linguists are authorities on what is correct and what is incorrect in a given language. But linguistics is the science of language; it treats language and the ways people use it as phenomena to be studied much as a geologist treats the earth. Linguists want to figure out how language works. They are no more in the busin
Bad blood - A case study of the Tuskegee syphilis project
Syphilis is a venereal disease spread during sexual intercourse. It can also be passed from mother to child during pregnancy. It is caused by a corkscrew-shaped bacterium called a spirochete, Treponema pallidum. This microscopic organism resides in many organs of the body but causes sores or ulcers (called chancres) to appear on the skin of the penis, vagina, mouth, and occasionally in the rectum, or on the tongue, lips, or breast. During sex the bacteria leave the sores of one person and enter
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
Discrimination, Distrust, and Racial/Ethnic Disparities in Antiretroviral Therapy Adherence Among a
Objective: Although discriminatory health care experiences and health care provider distrust have been shown to be associated with health care disparities, little is known about their contribution to racial/ethnic disparities in antiretroviral therapy adherence. We therefore sought to assess the extent to which discriminatory health care experiences and health care provider distrust influence treatmentrelated attitudes, beliefs, and self-reported adherence in a national sample of HIV-infected pa
Racial Differences in Cardiac Catheterization as a Function of Patients’ Beliefs
Objectives. We examined racial differences in cardiac catheterization rates and reviewed whether patients’ beliefs or other variables were associated with observed disparities. Methods. We did a prospective observational cohort study of 1045 White and African American patients at 5 Veterans Affairs (VA) medical centers whose nuclear imaging studies indicated reversible cardiac ischemia. Results. There were few demographic differences between White and African American patients in our sample.
The New Paradigm for Financial Markets: The Credit Crisis of 2008 and What It Means
In the midst of the worst financial upheaval since the Great Depression, George Soros explores the origins of the crisis and its implications for the future. Soros, whose breadth of experience in financial markets is unrivalled, places the current crisis in the context of decades of study of how individuals and institutions handle the boom and bust cycles that now dominate global economic activity. 'This is a once in lifetime moment', says Soros in characterising the scale of financial distress
