6.1 Reliable information

Information is worthless if you have no trust in it. This has always been the case, but there are issues of trust that arise specifically in the context of modern information and communication technologies. Think about the following:

  • You do a search on the Web and get results from several different sites. Do you trust the information in them all? How do you decide which are the most trustworthy?

  • You get an email, a letter or a phone c

5.14.3 Electrodialysis

Electrodialysis is an electrochemical process in which ion transfer separates salt from water. It is effective only for substances that can be ionized: for example, salt (NaCl) becomes, in solution, a mixture of Na+ and Cl ions. (Silica, on the other hand, does not ionize and hence is not removed by electrodialysis. It could, however, be removed by reverse osmosis.) When electrodes, connected to a suitable direct current supply, are immersed in a salt solution, curren

1.2 The hard side of Glasgow

Prior to its currently projected image of dynamism, Glasgow was regarded as the place which best illustrated all that was wrong with the modern industrial city: ‘Once called the “second city of the British Empire” because of its size and industrial might, Glasgow had sunk so low that even the locals disdained it’ (Bryson, 1989).

3.1 3.1 Introduction

Regionalism has grown remarkably since the high point of state centralism in the Second World War period. A succession of factors have come into play – uneven economic development, threats to regional cultures and languages, the decentralisation of some states, and more recently the impact of globalisation and European integration. The effects have been cumulative, with old factors continuing to operate while new ones were added, including, as we shall see

4.1 Exploring the claims about crime

The claims of the common-sense story of crime that we unearthed in Section 3 were, broadly speaking, about the start of the story (how things were then) and the end of the story (how things are now). But most stories have a middle. A middle that gets you from the beginning to the end, that explains how one state of affairs is transformed into another. The former claims are primarily descriptive. The claim in the middle would be explanatory. It would need to address questions lik

2.5.1 The reductionist perspective

Although theology had been thought of as ultimate knowledge, in post-Enlightenment thought, religion came to be seen by many in the West as a hindrance to progress and the advancement of human knowledge. Some came to believe that a rational and scientific way of looking at the world, unconstrained by religious belief and ‘superstition’, would lead to religion becoming redundant.

In the nineteenth century, this idea was boosted by Darwinian theories of evolution. Charles Darwin’s <

Introduction

The majority of people who sleep on the streets, and in hostels and night shelters are men. However, the number of women, particularly younger women, in these circumstances has increased (Anderson et al., 1993). They are often people with complex care and support needs, which go way beyond the provision of accommodation. But, as you will learn in this course, complex needs are both a cause and a product of homelessness.

In this audio course, you will hear from four people, who will each

7.3.1 Physical methods for demonstrating an interaction between proteins

To identify those unknown proteins in a complex mixture that interact with a particular protein of interest, protein affinity chromatography can be used (Figure 49a). This approach uses a ‘bait’ protein attached to a matrix. When this baited matrix material is then exposed to a mixture of proteins, only proteins that interact with the

Science comics as tools for science education and communication: a brief exploratory study
A paper based on the author’s dissertation research which examined the use of science comics as tools for science education, scientific literacy and communication. The paper gives an overview of the comics that already communicate science and a literature review shows that comics can be used for encouraging scientific literacy with education and communication as its basis. It also analyses why there is a lack of studies about science comics and suggests potential reasons and questions which cou

Another common secondary structure is the β pleated sheet, which contains extended stretches of polypeptide chain with hydrogen bonds between neighbouring strands. In parallel β pleated sheet, polypeptide strands run in the same direction (i.e. from N- to C-terminus) whereas in antiparallel β pleated sheet, neighbouring strands extend in opposite directions (Author(s): The Open University
