4.10 Retouching

In addition to the efforts made before exposure to show sitters at their best, portrait photographers regularly retouched the negative to remove or improve any perceived defects or blemishes. Before the 1860s, in Britain retouching was generally criticized for interfering with the ‘truthfulness’ of the photographic image. By the mid-1860s, however, the issue became the subject of intense debate and discussion and the journals published details of the various techniques available at the ti

7 The jury

The jury system has existed in Britain since the eleventh century, although its functions have changed over the centuries. The first juries very often acted as witnesses reporting on events they knew about. Modern juries should know as little as possible about the case before the trial and are mainly used in criminal trials in the Crown Court. Their role in the Crown Court is to listen to the evidence and decide the guilt or innocence of the accused based on the facts presented to them. They

6 Conclusion

At the beginning of this unit we recalled four views of development. The ‘grand theories’ reviewed here can be seen to capture elements of those views:

  • development as discipline – behaviourism;

  • development as experience – social learning theory;

  • development as ‘natural stages’ – constructivism;

  • development as interaction – social constructivism.

However, these theories have mo

1.1.1 Frequency

Frequency refers to how often or how frequently someone should exercise. The American College of Sports Medicine (ACSM) recommends an exercise frequency of three to five days per week to improve or maintain VO2max (ACSM, 2006). They suggest that people training for sport may need to exercise more frequently.

Introduction

The course that follows presents two sections from different parts of the Maths for Science teaching text - a course designed to help OU students acquire the knowledge and skills to tackle the mathematical aspects of science courses they are likely to go on to study. The first (Section 1), covering the first six of the learning outcomes, is about measurement. Observation, measurement and the recording of data are central activities in science. Whether measurements are made using simple inst

Introduction

This course is concerned with a special class of topological spaces called surfaces. Common examples of surfaces are the sphere and the cylinder; less common, though probably still familiar, are the torus and the Möbius band. Other surfaces, such as the projective plane and the Klein bottle, may be unfamiliar, but they crop up in many places in mathematics. Our aim is to classify surfaces – that is, to produce criteria that allow us to determine whether two given surfaces are

1. Introducing diversity and difference

This course focuses on issues of difference and diversity in a specific sense. Rather than analysing diversity in terms of kinds of communication and relationships, the focus here shifts to diversity in terms the people involved in interactions in care settings. Again, it is simple common sense to state that ‘good’ communication in health and social care services involves acknowledging and responding to the diverse needs and backgrounds of everyone involved, whether service

2.4.4 Manipulation

Suppose I take a digital photograph of myself for my website. Horrified by my wrinkled, baggy appearance, what can I do? Actually, with the right software I can do more or less anything I like: I can smooth out the wrinkles; I can restore the grey hair to its former splendour; I can even put in a background of books to give me a scholarly appearance. In fact, I can so improve the picture that if you met the real me you probably wouldn't recognise me.

2.2 Pressure in the atmosphere

The sounds we hear generally consist of rapid fluctuations of air pressure in the atmosphere that surrounds us. Sound can also be transmitted through other media, for instance water, so not all sound consists of fluctuations in air pressure. However, for the purposes of this discussion I shall confine myself to sound in air.

These fluctuations in air pressure are caused by a local disturbance to the air pressure, which might be sudden and transient – for example, when a paper bag is b

2.2 Identity and identities

Self-identity

In the previous section we considered the importance of people’s individual biographies to an understanding of who they are. Such biographies play an important part in making us who we are. In this section we will explore some of the ideas that have contributed to social workers’ understanding of the concept and importance of ‘identity’. These ideas are all examples o

Mabel Holmes' Diary, 1935-1939, part 2
Mabel Holmes, a longtime Topeka resident, kept a daily diary from January 1, 1935-December 31, 1939. During this time, storms resulting from the severe drought conditions blanketed the state in dust so thick that it could be pitch black in the middle of the day; Kansans were coping with an economic depression even worse than our current one; the threat of a second World War in Europe was looming. Against this backdrop, Mabel talks about the news, weather, shopping, outings with her sister, Elma
