The procedure of Question 15 for determining the instantaneous velocity of the car can be carried out for a whole set of different times and the resulting values of vï»¿ï»¿x can be plotted against t to form a graph. This has been done in Figure 28, which shows how the velocity varies with time. At time t = 0 s, the car has zero velocity because it starts from rest. At later times, the velocity is positive because the car moves in the direction of incre

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 Pity then â€“ or more like disaster â€“ that its fundamental ideas are centuries out of date, but still dominate decision-making for the future.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

6.1 Introduction

The international level can be viewed as an arena of politics in its own right and not just as a context for states and other actors. If we think of the international world in this way, how should relations between states, and other actors on the international stage, be constructed? To what extent should those relations be regulated? We can ask whether relations between states, and states' policy making, should be dictated by allegedly universally shared human rights principles, or by other o

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 â€˜the worst form of government except for all the others that have been triedâ€™. 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 â€˜extremistsâ€™ or â€˜ideologuesâ€™, 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

3.4 Databases

At a basic level, a database is a collection of information which can be searched. It is a way of storing, indexing, organising and retrieving information. You may have created one yourself to keep track of your references - or your friends' names and addresses. They are useful for finding articles on a topic, and can be used to search for many different types of information.

You may find some of the following databases useful for your topic. They contain different types of information
