Authorial Voice, Implied Audiences and the Drafting of the 1988 AIDS National Mailing

Dr. Veeder analyzes changes throughout many drafts of the 1988 ANM and finds that the process of negotiated drafting contributed to its success. She also concludes that risk communicators should focus attention on audience needs rather than competing truth claims

Small Changes, Big Impacts: Prairie Conservation Strips

Agriculture in Iowa owes its immense productivity to an extreme trade-off. Once, perennial prairie covered 85 percent of the state, and its deep root network built and held together a fertile topsoil layer many feet deep. Now, more than 85 percent is in agricultural production, with the majority in row crops

The Use Of A Computer As A Teaching Device For Certain Concepts Of The Calculus

Many concepts involved In the calculus can be presented in a nore obvious Banner by the use of a computer. So much of the calculus involves many very small values that become tedious for a beginning student to calculate. In doing the calculations he loses sight of his objective in the problem. This paper attempts to explore the various possibilities for use of the computer in teaching a course In elementary calculus. There are three basic areas of calculus where a computer could be used as an aid for teaching. These are the limit, the integral calculus and graphing. The underlying current throughout calculus Involves the limit concept. The mechanics of working several values through a function can become very tedious, bit with a program that is rather easily written, many values can be put into the function and the limit can be printed, along with the intermediate values used to arrive at the actual limit. Using the limit, but incorporating it within another idea, the calculus student looks at the areas under curves when he begins the integral calculus. Various methods can be used to approximate areas under curves with only the integral giving the exact value. Programs can be written to find values for the trapezoidal approximation and Simpson’s rule. These will vary from the actual value, but the error should be rather small, Various other approximating formulas are used In calculus that are readily adaptable to computer methods. One of these is Newton’s Method for Approximating Roots, The third area is graphing, which is not specifically calculus, but a tool used very often in calculus, Although the computer can only produce approximate graphs, they are explicit enough to merit investigation. Ibis paper does not try to give explicit ways to teach calculus, but instead points out areas where the computer could be applied, if the circumstances were right. One must keep in mind that "certain types of problems are easily solved by computer and that other types of problems are best left to people,*^ The reader is asked to keep in mind that this paper is not advocating continual use of the computer in the teaching of every calculus class, but only supplementary use in particular areas, "...students should understand the relation between computers and mathematics. Mathematics is an important and widely used tool - and will continue to be in the future. Computers are an aid to using that tool and will become a greater aid in the future. The combination - mathematics plus computers - is essential to the student who wants to make effective use of mathematics in our technological society,"

Ceci n’est pas un argument appropré (this is not a proper argument)

This provocation poses questions of various sizes ‘inspired’ by some of the written publications that have theorised the concept of Practice as Research and drawing on lessons learnt from supervising PhD’s (with and without PaR). It consists of ‘musing’ rather than a proper argument and makes reference to feminism. Some readers might find both of these things very irritating. Throughout the course of its musing, questions asked include: ‘Is it acceptable to start a sentence with ‘And’ in academic writing?; ‘What does and does not have the status of ‘theory’? And who does and does not have the status of a theorist? and ‘What is a proper argument?’ No answers are provided and no conclusions drawn

Use by Honeybees of Flowering Resources In and Around Corn Fields

Corn seeds and seedlings are susceptible to attack by several early-season insect pests. Seed treatments have emerged as a means of reducing these insects. Seed-adhered insecticides include members of the class of chemicals referred to as neonicotinoids, which have been demonstrated to adversely affect honeybees. Pollen and nectar that foraging bees collect may be contaminated with neonicotinoids via direct spray, by plant translocation following treatment, and by contaminated dust generated during treatedseed planting
