5.1.1 What is DNA? DNA (deoxyribonucleic acid) is frequently in the news for four main reasons. DNA can be used in crime detection to eliminate innocent suspects from enquiries or, conversely, to identify with a very high degree of probability the guilty. DNA is now used in medicine to detect the possibility that diseases having a genetic origin may occur in an individual. This enables doctors to prescribe preventative treatments. It is hope
A brave new world
In today's fast moving technological world, successful companies will be those brave enough to invest in start-ups and create their own competitors. Taking the example of Kodak, who floundered in the face of emerging digital technologies, Dr Kamal Munir explains the importance of adaptation, but points out, that merely hooking new technologies into a business model to prolong the life of existing technologies is not enough: "Companies need to invest equity into start-ups, they need to create the
1.6 Valuing diversity Social workers need to recognise diversity: valuing and respecting service users – irrespective of, for example, their ethnicity, gender or age – is central to good practice. It is also about working in a way that counters the unfair or unequal treatment of individuals or groups on the basis of their race, gender, class, age, culture, religion, sexuality or ability. There is a growing body of law that seeks to prohibit and punish a range of discriminatory behaviours in various kinds of so
4.1 Legacy technology The aim of Section 5 is to examine some of the issues and problems which affect the devekopment of Internet, e-commerce and e-business applications. The World Wide Web was developed as a way of dispensing documentation within the large research laboratory at CERN in Geneva. I am sure that the originator of the technology, Tim Berners-Lee, did not realise at that stage how it would expand and become a major component of our economic infrastructure. Because many of the developers o

2.4 Examples of layer functions There are several functions that can be performed at one or more of the OSI layers. Some of the more common ones are discussed below.
Connection control
For connection-oriented services, a connection must be established between peer entities. A connection has three phases: connection set-up, data transfer and connection clear. If the peer protocol supports connections, each protocol data unit type corresponds to a primitive type; for instance, a connection request primiti
2.2 Narrative events Any narrative is made up of a series of events or incidents, arranged in a particular way. This can be defined as the plot of the story. Consider, as an example, Ernest Hemingway’s appropriately entitled ‘A Very Short Story’ (Hemingway, 1944, pp. 135–6). Different readers will summarise the story in different ways, allocating different levels of significance to various narrative events. If you can access a copy of the story, you might like to try and summarise it yourself and compare

Many spam messages have a line at the bottom offering to unsubscribe you from a mailing list, but you should be very wary of doing this. Quite often the senders of the spam will use the 'unsubscribe' option to verify that your email address is live. They may then sell your address to other people for use in spamming. So using the unsubscribe option can increase your spam rather than reduce it. Our advice is never to use the unsubscribe option unless the mail you receive is from a well-known, Learning to learn: learning can mean change 1 Sets In Section 1 we discuss the idea of a set and describe some ways to define sets. We illustrate our discussion with sets of numbers and with geometrical sets of points in the plane. We also explain how to check whether two given sets are equal and whether one set is a subset of another. Finally, we introduce the set operations of union, intersection and difference.

Author(s): 8.1 Introduction You know by now that plants can synthesise all the complex molecules that make up their tissues and seeds from very simple molecules - water, carbon dioxide and minerals from the soil. Mammals, on the other hand, need to take in many complex molecules ready-made, and some foods do not contain the right amounts or the right mix of nutrients. They have evolved various strategies to overcome the shortfalls, some of which are described in this section. 1 What is monitoring? Monitoring means gathering evidence to show what progress has been made towards strategic priorities and targets and the implementation of policies. Evaluation means making judgements about the results. DfES 2003, National Training Programme for New Governors, Module 2, p. 4. Monitoring is a key aspect of governors' remit; it is necessary so that governing bodies can carry out their strat
