Innovation Design: Sustainable Communities
Can you picture the future in a world without fossil fuels? Perhaps you think that living an "alternative" lifestyle has to mean painful and radical changes to the way you live now. This album looks at various small scale initiatives which show that living sustainably may not be as unpalatable as you might imagine. Bedzed, Findhorn, Hockerton, Samsoe Island; these are all decentralised communities at the forefront of a major social and technological experiment. In our world of finite resources a

Introduction

This unit examines how self-assembled structures based on lipids and proteins provide a framework for cellular processes.

This OpenLearn course is an adapted extract from the Open University course T356 Engineering small worlds: micro and nano technologies.

4.3.3 Getting at the activation energy

The final trick I want to show you with Arrhenius's law is how to extract the constants r0 and Ea from experimental data. If the Arrhenius equation (Section 4.3.1) is 'turned inside out' by taking natural logarithms of both sides it becomes:

3.2 Sub-state forms of nationalism

The advancement of democracy in contemporary Western nation-states and the intensification of globalisation processes have encouraged the re-emergence of nationalist movements representing oppressed or silenced nations that demand the right to self-determination. In the case of ethnic groups formed by people of immigrant origin, democracy has provided them with the tools to pursue the right to develop and practice their indigenous culture and language alongside those of the host country.

3.1 Modelling properties

This section provides a model for properties interpreted in terms of the average thermal energy of all the constituent atoms of a material. Since absolute temperature T is a measure of average atomic kinetic energy, we shall expect to be looking at properties that change gradually with T, roughly proportionally, over a wide range. In terms of the classification introduced in Author(s): The Open University

2.1 Boiling water

Whether it's to wash clothes, make a cup of tea, or just make it safe to drink, water often has to be heated – sometimes to boiling point. There are many ways to do this, but a very common means is some form of electric water-boiler, such as a kettle or an urn. In all but the crudest ones, a device is fitted to ensure that heating does not continue once the boiling point of water is reached.

In deciding on the type and design of such a device, we can suppose that a company manufacturi

5.2.1 Providing evaluative feedback

One of the roles of a leader is to provide group members with feedback on their performance. This is often an uncomfortable process for both the leader and the recipient. The main reason for this is a failure by both parties adequately to distinguish between the individual and what is being evaluated. When criticism is carelessly given, it is easy for the recipient to take it as an attack on his or her self-esteem. The result is that the recipient resists the feedback and responds in a defens

4.3.2 Setting goals and objectives

Whatever the structure and culture of an organisation and the range of people involved, goals and objectives are usually seen as a valuable management tool. This is as relevant to a project team as it is to a whole organisation. What I will focus on here are some of the tensions and ambiguities surrounding the management of goals, especially in the context of team development. To be effective in clarifying and achieving the team task, we need to take account of the variety of (often conflicti

4.1 Types of projects

Formal projects are a familiar part of nearly all work situations and are often a staple part of some organisations. Because of this it is worth looking at some of the features of formal projects and their management, as they have some different characteristics from other ongoing activities.

To write about projects, we have to define what they are and describe how they arise. Projects and project work are often contrasted with process: 'process', in this sense, describes the normal day-

3.1 Belonging to a group

Because work groups are of central significance in the functioning of an organisation they have been studied intensively, and much has been written about group processes. In this reading it would be inappropriate to attempt to review this vast literature, which covers an enormous range of topics and aspects of groups. Instead, I focus attention here on two particular aspects of groups. First, I examine the nature of the contracts within a group: what it is that people gain from belonging to a

2.4.3 Polarization mode distortion

Because light is an electromagnetic wave, it has a ‘state of polarization’, which, for light in single-mode fibre, is at right angles to the path of the fibre. If you've not encountered electromagnetic waves before, all you need to appreciate is that as light travels down the fibre the electromagnetic field has an orientation across the fibre (Author(s): The Open University

5.9 Ethical reasoning

Now Ned's got three things. He's got the money that is presumably ‘good’. He's got his defence policy, which he thinks is ‘good’. Ros then introduces the well-being of the community. They are all ‘goods’ but each pulls in a different direction. Any judgement that Ned makes has to be based on an aggregation of these things. But, of course, these are quite different kinds of things, they are incommensurate, so adding up these things is not a straightforward proposition. Ros is hopin

4.4 Legitimacy vs rights

Another major theme in the play relates to the surveillance equipment. The general question about surveillance is raised as soon as we are told that the company is installing a system for that purpose. You might be inclined to think that the government is entitled to deploy a surveillance system because there are problems that need to be dealt with, somehow; perhaps you view the system as just a technological extension of the police. However, individuals too have rights, and this raises quest

1 Putting the unit in context

This course, taken from T883 Business operations: delivering value, is concerned with the management of ‘processes’ – the organised set of resources and related activities that are essential for the delivery of goods and/or services to customers. These processes or ‘operations’ form the very essence of any enterprise, and it is critically important that they are managed well to be effective and efficient.

The full course consists of three main blocks of study:

4.4 Evaluate solutions

If the obvious solution has been identified and everyone is in agreement, then a formal evaluation of solutions is unnecessary, and we would move on to modelling the design. However, if there is dissent then some stricter method of elimination is required, and this is usually achieved through a process of rank-ordering. There is little to be lost and potentially much to be gained by returning to the customer at this point for opinion, clarification or guidance.

1.3 Innovation by development

Innovation by development is about changing the bit that doesn't work, or that could work better, to improve the function of the whole for reasons of cost, performance, ease of manufacture or competitive edge. You probably noticed in Box 1 'Innovation by context – an example' that Baylis had to

5.15 Summary of Section 5

It is probably worth summarising some of the main points you should take away from this section on primary vibrators. The first thing to remember is that when an instrument is excited, it vibrates strongly at certain frequencies called natural (or resonance) frequencies. The reason for this is that standing waves are set up in the instrument's primary vibrator at these frequencies. The next thing to note is that some primary vibrators, such as a string or an air column, have natural frequenci
