2.4.1 Multimode distortion

With multimode fibre, the main cause of pulses spreading is the multiple paths that signals can traverse as they travel along the fibre. This phenomenon of multimode distortion is illustrated in Figure 5.

12.1 Gathering data

In this section I will review some of the approaches and methods used by companies for identifying and exploiting marketing opportunities.

All over the world, producer companies have increasingly learned to keep a careful watch on emerging consumer requirements and changing user needs and wishes. They have not only learned to listen to what consumers say, but to watch what they do. Techniques used in market research to gather consumers’ views on products include both quantitative meth

8.1.1 Visibility

Recall that a key usability design feature identified by Donald Norman – from his analysis of using everyday objects such as doors – was visibility. An everyday object such as a door, or a control such as a button on a product should appear to be obvious about how it is used, and indeed it should perform that obvious function. For example, is it obvious how you insert a disc into a player? Is it obvious how you switch the machine on, adjust volume, and so on?

8.1 Making usable products

This section reveals that many modern products need to usable by our minds as much as our bodies. Products need to be understandable, and present information and feedback in meaningful ways.

A lot of ergonomics research is aimed at establishing guidelines, standards or rules that can be applied by designers in a variety of situations. Where this applies to the physical use of products, much of it is based on standard body measurements. These body measurements are known as anthropomet

7 Ergonomics and human factors

This section discusses designing for human capabilities and limitations. It introduces the study of ergonomics which can offer general guidelines as well as specific suggestions for good, user-centred product design.

Taking the user as the central point of reference for the design and evaluation of products is the approach encouraged by ergonomists.

The field of ergonomics (also known as human factors engineering) is the systematic study of human capabilities, limitations and requ

8.8 Hinduism as ‘a world religion’: a more recent understanding

Traditionally, as we have seen, a Hindu was someone born to Hindu parents and into a caste with its appropriate dharma. The link between religious practice and a whole way of life bound the individual into a community from birth. Regional factors, parentage and caste affiliation largely determi

4.3 Business and enlightenment: Manchester 1789–99

Manchester's dynamic business environment, particularly that of the new cotton industry, presented many opportunities for enterprise, even to those with modest capital. By 1790 Owen had joined John Jones, probably another Welshman, making spinning machinery. The next logical move was into cotton spinning itself, and very quickly Owen had established a reputation as a manufacturer of fine yarn, selling as far afield as London and Scotland. When in 1792 one of the town's leading merchant capita

4.11.1 Debating and negotiating meaning

The two briefings in Boxes 4.10 and 4.11 illustrate other technological approaches to supporting socially based forms of knowledge generation, with the common theme of facilitating negotiation and debate among stakeholders. These are examples of tools which can assist communication between communities of practice as they seek to understand each other's perspectives.

Activity 10: Critical reflections on Hofstede

Allow 60 minutes for this activity.

You have spent most of this unit working with Hofstede's ideas. He is one of the pioneers of the study of national culture and its impact on organisations, and his work has been very influential.

My aim so far has been to help you understand Hofstede's cultural dimensions and to become familiar with how they can be used to analyse one of the main environments within which organisations operate. National culture is also one of the factors

2.7 Tracking progress

Gantt charts and critical path diagrams are useful for tracking project activity and for making necessary changes to the project plan. Project-planning software may also be used; the original chart is kept as the standard and any modifications are superimposed.

The example of the joint strategy for commissioning training services demonstrates how tracking produced information that led to a change of plan.

1.5.1 The co-production of meaning

The third sense in which discourse is a social action refers to the origins of meanings. Meaning emerges from complex social and historical processes. It is conventional and normative. We have some idea what it signifies to say Prince Charles is a proud man because we are members of a speaking community and culture which has agreed associations for ‘proud man’. We draw on those to make sense. Meaning is also relational. Proud signifies as it does because of the existence of other t

9 Conclusion

In this unit we have explored the mutual constitution of personal lives and social policy through an analysis of the implications of different aspects of citizenship on the lives of refugees and asylum seekers. We have seen that legislation, social policy and practice concerned with asylum have profound effects on personal lives. Crucially, we saw that the very words used to describe people, their access to welfare, rights to work, legal status and the procedures for becoming a British citize

4.1.3 No dynamic web pages

Another example of a problem with web servers which arises from their original functionality is the fact that web pages were designed to be static: they were files which were stored on a computer and delivered in their stored form to anyone using a browser to access them. Many e-commerce and e-business applications require something much more dynamic, for example there are a number of financial service sites on the web which provide customers with up-to-date stock and share prices.

4.1 Preparing

In the preparation phase you should pause before starting a new section of work and think about it as a whole. What needs to be covered? What are the various components of this block of work? What are the learning objectives or outcomes? What will you need to know and be able to do at the end of it? What is required in the assignment?

There are two main activities during this phase, both directly related to your course work and assignment:
