Learning outcomes

After studying this course, you should be able to:

  • describe the principal differences between a eutrophic and an oligotrophic ecosystem

  • explain the mechanisms by which species diversity is reduced as a result of eutrophication (Questions 2.1 and 2.2)

  • contrast the anthropogenic sources that supply nitrogen and phosphorus to the wider environment, and describe how these sources can be controlled (Question 3.1)

  • describe how

Preamble

The two main types of superconducting materials are known as type-I and type-II superconductors, and their properties will be discussed in the remainder of this course. All of the pure elemental superconductors are type-I, with the exception of niobium, vanadium and technetium. The discussion of the effects of magnetic fields and currents on superconductors earlier in this course has been confined to thin cylinders of type-I materials like lead or tin in a parallel magnet

Money talks: Trumponomics
Donald Trump's presidential campaign is astounding political analysts and flummoxing economists; and we also look at whether high denomination bank notes are useful only to criminals Correction: We attribute an analysis of Donald Trump's economic proposals at 2:40 minutes to the Tax Policy Centre, when in fact it is from the Committee for a Responsible Federal Budget. We regret the error.

Doughnut Economics: seven ways to think like a 21st century economist [Audio]
Speaker(s): Kate Raworth, Professor Oriana Bandiera | Economics matters. Its theories are the mother tongue of public policy, the rationale for multi-billion-dollar investments, and the tools we use to tackle global poverty and manage our planetary home. Pity then – or more like disaster – that its fundamental ideas are centuries out of date, but still dominate decision-making for the future. Instead of criticising the past, this book takes the long view forwards, identifying seven insights

1 Making, interpreting and applying rules

The aim of this course is to introduce you to the processes of making, interpreting and applying rules.

We often think about social rules, most of which are unwritten and which we observe because we have a shared social understanding of what they are. We are now going to think about a different kind of rule. A definition of a rule (as opposed to a habit, custom or role) is shown in Author(s): The Open University

Differences in the neural basis of Chinese and English reading
Introduction: Previous functional imaging studies comparing Chinese and English reading have reported that a left middle frontal region is more activated by Chinese reading and the left superior temporal cortex is more activated by English reading (Tan et al. 2001; 2003). We investigated this finding and its interpretation by conducting a functional magnetic resonance imaging (fMRI) study of reading in China and England using monolingual adolescents who spoke Mandarin or English respectively.

The Worst Form of Government? [Audio]
Speaker(s): Beatrix Campbell, Professor Peter Hallward, Dr Edward Kanterian | Winston Churchill famously described democracy as ‘the worst form of government except for all the others that have been tried’. While not exactly a resounding endorsement, something like this sentiment is strongly held by most people in Western societies. Those who challenge it are branded ‘extremists’ or ‘ideologues’, with special suspicion reserved for those who incorporate unfamiliar cultural or religio

Modelling pollution
The cleaning up of the North American Great Lakes is one of the great success stories in pollution control. Modelling gives scientists the tools to forecast outcomes in a complex environment: how will the pollution accumulate? what will happen if pollution is stopped all together? The two video tracks on this album demonstrate how modelling techniques provide a scientific basis for the political decisions that have revived the area. The material forms part of course MSXR209 Mathematical Modellin
