7 Summary

The theme of this unit has been the impact that information and communication technologies have had on the news industry. I introduced this theme with a short historical overview of technology in the news industry followed by a look at how technology is used for newsgathering.

We have been looking in some detail at aspects of the underlying technologies used in newsgathering, including the basic components of digital camcorders and the methods of signal transmission over wires. We have

4.2.3 Lens system

The function of the lens system is to project an image onto the CCD light sensor. A well-designed system ensures that the image is sharp – in focus – and bright. To achieve this, what is needed is a good-quality glass lens (or rather a series of lenses) and accurate focusing. The brightness of the image depends upon the size of the lens. The bigger the lens, the brighter the image, but bigger lenses are more difficult to make and therefore more expensive. Also, of course, bigger lenses me

1 Bringing the news on the back of a horse

We seem to be surrounded by ‘news’ these days, but it was not always like that. In Shakespeare's Henry IV Part 2, Falstaff hears the news that his former friend and drinking partner, Prince Hal, is now King Henry V, following the death of Henry IV. It is a comic scene set in Gloucestershire, 200 km from the royal court in London, and it is clear that before the messenger (called Pistol) arrived on horseback Falstaff did not even know that Henry IV had died.

8 CASE tools

Computer Assisted Software Engineering (CASE) tools were developed to support the professional system developer and improve their productivity in the complex task of developing large information systems.

The benefits that may accrue from the use of such tools are many. From a developer’s viewpoint, they provide support for modelling aspects of the system using a variety of notations and techniques: from diagrams to mathematics and text, producing prototype code, and even verif

8.2 Example of a university registration data model

Here is a statement of the data requirements for a product to support the registration of and provide help to students of a fictitious e-learning university.

A UK-based e-learning university needs to keep details of its students and staff, the courses that it offers and the performance of the students who study its courses. The university is administered in four geographical regions (England, Scotland, Wales and Northern Ireland).

Information about each student should be initially

8.1 Introduction

One type of data model is an entity–relationship data model.

Experience has shown that data can be best described by relationships between entities. An entity is anything of interest about which data is recorded, such as roads, weather stations, trucks and weather station readings in the IceBreaker project in the book MRP. In general, there will be many relationships (or associations) linking the entities. A trivial example is the fact that a given weather reading

1.6 Implementation

Implementation involves the construction of a database according to the specification of a logical schema. This will include the specification of an appropriate storage schema, security enforcement, external schema, and so on. Implementation is heavily influenced by the choice of available DBMS, database tools and operating environment. There are additional tasks beyond simply creating a database schema and implementing the constraints – data must be entered into the tables, issues relating

School Governors: Being strategic
Why are schools in the UK run by school governors? This unit will examine how the role has developed and the main tasks and responsibilities that exist today. We will also look at the need for self-evaluation and how the setting of a clear strategic direction can help governors achieve the required targets. First publis

4.5.2 Thinking about knowledge and skills

As you learned in Section 3, there are various routes to acquiring knowledge and skills including formal and informal learning opportunities, and individual and social routes to learning.

We now encourage you to think first about formal approaches to acquiring the knowledge and skills you might need and then about informal learning approaches.

3.3.6 A ‘health warning’ about groups

It can be great to belong to a group, especially if you are a highly respected ‘core’ member. Other people can look up to you and ask you to share your expertise. The process of moving from being a peripheral member to being a core member can also be very satisfying. However, groups are sometimes defined as much by whom they exclude. Groups may not just have ‘insiders’; they have ‘outsiders’ who are not seen as part of the group. Often this may not matter much. No one can be a mem

This unit is about using learning to bring about personal change. This assumes that learning can help achieve such change. Section 2 aims to be the first step in showing you how this is possible. This section has three separate but related aspects:

  1. Section 2 looks at what the word ‘learning’ includes. This turns out to be a very wide ranging idea that suggests that human beings learn all the time. What we learn has impo

9.7.1 Take a leading role in managing an activity

If the planning has been considered and negotiated and schedules and resources identified, managing the group progress may just involve checking on progress against agreed deadlines. You need to know how to obtain and use effectively the resources needed (such as materials, tools, access to equipment, help from others) and try to make constructive use of time, both yours and that of other group members. Managing an activity also means being able to delegate and negotiate quality and standards

8.9 Drawing ideas together

This key skill has used a three-stage framework for developing your skills. By developing a strategy, monitoring your progress and evaluating your overall approach, you take an active role in your own learning. But learning does not necessarily follow a path of steady improvement, it involves change: revisiting ideas, seeing things from different perspectives, tackling things in different ways.

You are unlikely to be able to complete your work by working through it from beginning to end
