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

1 Symmetry in two dimensions

In Section 1 we discuss intuitive ideas of symmetry for a two-dimensional figure, and define the set of symmetries of such a figure. We then view these symmetries as functions that combine under composition, and show that the resulting structure has properties known as closure, identity, inverses and associativity. We use these properties to define a group in Author(s): The Open University

2 Schemes run by Swansea Cyrenians in 1999

A hostel, which provided accommodation for 13 people, predominantly men, in individual rooms and an overflow shed. It was run in partnership with the Family Housing Association. Three-quarters of its funding came from the Welsh Assembly, and a quarter from the local authority.

Another important source of revenue was Housing Benefit, through which residents were able to pay their accommodation charges. This varied enormously. Residents classified as ‘vulnerable’, like those with ment

5.1 Standing waves

You learned earlier that when a musician plays a note on an instrument, they supply it with energy that causes the primary vibrator to oscillate at certain specific frequencies. In Section 5 we are going to look at what determines these specific frequencies for some of the primary vibrators found in different instruments.

In Unit TA212_1 Sound for music technology: an introduction, we talk about travelling waves: that is, waves that propagate outwards away from their sourc

4.9 When there's too much to do

This can be a real problem in large conferences. If, for whatever reason, you join a conference later than the other participants, or are unable to be involved for a while, the prospect of joining in can be a bit daunting. There will be lots of messages you haven't read and you may feel that everyone else knows each other.

The main thing to remember is that everyone will be pleased to ‘see’ you when you do join in, and will be helpful and supportive. Here are some strategies you can

Music and its media
This free course, Music and its media, examines some of the main ways in which music is transmitted. It considers how the means of communicating a particular piece can change over time; and how the appearance and contents of a source can reflect the circumstances in which it is produced. The course focuses on three examples of musical media that allow us to study music of the past: manuscripts of sixteenth-century Belgium, prints of eighteenth-century London, and recordings of twentieth-century

2.6.1 (a) Using Lego as a model

In this kind of building set, there are a limited number of types of block and each block has a particular shape. Just as importantly, each one has a particular way in which it can link to other blocks because of the way the studs are arranged.

The blocks can help you see how the atoms link in a molecule of water. Look at Figure 7 where the red brick represents an oxygen atom and the white bricks represent hydrogen atoms. There are only two locations where the hydrogen atoms can join th

2.8 Polar form

You have seen that the complex number x + iy corresponds to the point (x, y) in the complex plane. This correspondence enables us to give an alternative description of complex numbers, using so-called polar form. This form is particularly useful when we discuss properties related to multiplication and division of complex numbers.

2.6 Summary of Section 2

The results of the visual attention experiments we have considered can be interpreted as follows.

  • Attention can be directed selectively towards different areas of the visual field, without the need to re-focus.

  • The inability to report much detail from brief, masked visual displays appears to be linked to the need to assemble the various information components.

  • The visual information is captured in parallel, but assemb
