Diagramming for development 2 - Exploring interrelationships, is a free course that introduces you to the diagramming techniques of Influence diagrams, Multiple Cause Diagrams and Cognitive Maps. Using a case study project based in Africa, this unit illustrates the powerful use of systems diagramming for international development management. This is a companion course to Diagramming for development 1: bounding realities.

Diabetes is an increasing problem among both adults and children. This free course, Diabetes complications, looks at the way the condition is managed once it has been diagnosed in order to reduce the risk of further complications. You will look at the role of each member of the team involved in the diabetes annual review and look at the risk factors involved with certain diabetes complications.

Why is the way something looks important? Text, colour, images, moving images and sound all interact to produce a user-friendly environment within a user interface. This free course, Designing the user interface, will help you understand the effect each software component has on the user and explain how a consistent and thoughtful application of these components can have a significant impact on the look of the final product.

How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This free course, Crossing the boundary analogue universe, digital worlds, explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.

This free course, Data and processes in computing, will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.

This free course is an introduction to differentiation. Section 1 looks at gradients of graphs and introduces differentiation from first principles. Section 2 looks at finding derivatives of simple functions. Section 3 introduces rates of change by looking at real life situations. Section 4 looks at using the derivative of a function to deduce useful facts for sketching its graph. Section 5 covers the second derivative test, used to determine the nature of stationary points and ends by looking at rates of change, including the real-life situation, using differentiation to find acceleration.

The furore surrounding the so-called 'mad cow' diseases is an important and controversial episode of recent years. Although it peaked several years ago, the topic is still of great medical significance, influencing the way the public thinks about and experiences science and scientists. All of which is touched upon in in this free course, BSE and vCJD: their biology and management.

This free course is an introduction to Bayesian statistics. Section 1 discusses several ways of estimating probabilities. Section 2 reviews ideas of conditional probabilities and introduces Bayes’ theorem and its use in updating beliefs about a proposition, when data are observed, or information becomes available. Section 3 introduces the main ideas of the Bayesian inference process. The prior distribution summarises beliefs about the value of a parameter before data are observed. The likelihood function summarises information about a parameter contained in observed data and the posterior distribution represents what is known about a parameter after the data have been observed.

Risk is something that must be taken into account at all times when practising as an engineer. We accept risk as part of everyday life so there is a need to balance the risks of an activity against the benefits that it brings. This free course, Assessing risk in engineering, work and life, investigates how we can manage risks at work, in the home and in the wider community. Risk is tied in with accidents so it is vital to understand how accidents -----, how likely they are to occur and how they can be prevented. These subjects are all covered in this course.
