Social care, social work and the law
The law and aspects of the legal system have a massive impact on the lives of social workers, from defining policy and procedure to the actual process of day-to-day working. This album presents an encompassing and engrossing look at the interaction between legal and social teams, and how different professions and groups interact to ensure equality and representation for all members of society. Not only do these discussions offer an insight into the justification and implementation of policy, the

Challenging ideas in mental health
Mental health service users often feel - and often are - disempowered from taking control of their own destiny. The video tracks on this album tell the story of people who have been confined to the psychiatric wing of a large Northern hospital. Scripted and acted by mental health service users/survivors, A Quiet Night on Roundhay Wing presents an insiders' perspective on the people and practices that have dominated – and defined – their lives, often over many years. Although the events port

Understanding the past
Care can make deep inroads into personal lives and life narratives, so it is essential that care workers are sensitive to this and provide appropriate support. In this free course, Understanding the past, the history of Lennox Castle Hospital in Scotland provides a focus for considering the impact of institutional life. First published on Fri, 04 Mar 2016

5.6 Summary of Section 5

  • In 1997, the newly elected Labour government set in motion the asymmetric decentralisation of the UK by granting differing degrees of political autonomy to Scotland, Wales and Northern Ireland.

  • In 1997 referendums on devolution where held in Scotland and Wales. Their affirmative outcome in favour of devolution cannot of itself deliver constitutional entrenchment, but might reinforce its moral and political legitimacy.

5.2 Devolution in Scotland

Scotland endured a long and complicated process towards self-determination. In a 1979 referendum, the Scots voted in favour of the Labour government proposals to establish a Scottish Parliament, but, thanks to a special majority provision requiring at least 40 per cent of the registered electorate to vote in favour, devolution was rejected when only 32.9 per cent of the electorate voted in favour in the referendum.

5.3.2 Productivity difference

The preceding discussion has only considered what would happen if all women undertake less investment in human capital than men. If men and women invest to the same extent, human capital theory suggests that no wage differences would be observed. What happens, however, if there are differences in skill levels both between genders and within gender groups? To consider this we will also make the additional assumption that firms do not know when recruiting workers who are the most productive. Ho

The Final Cut
It is often said that a movie comes to life in the edit suite. Ben Harrex of Final Cut post production studios in London discusses five themes with examples; The Cut, The Dissolve, Cropping and Resizing, Titles and The Sound. Ben explains how the video editor has a huge amount of creative control over how the final product looks.

Natural intelligence
One goal of artificial intelligence is to build machines that can operate in the real world, with all its noise and uncertainty. Much of what we want machines to do (see, recognise, navigate, move, coordinate) is already done very well by simple creatures. In this free course, Natural intelligence, we look at how such creatures achieve these goals and start to understand how we can build machines with the same capabilities. Author(s): Creator not set

Introduction

There is more to computers and processors than simply PCs. In fact computers are ubiquitous in everyday life. This unit challenges how we view computers through the examples of processors in kitchen scales and digital cameras, as well as a work of art that, at heart, is a computer.

4.3 Character code functions

Many programming languages provide two functions associated with the character codes (see Table 2). We shall call these functions ASC and CHR. ASC takes a character as input, and returns the integer giving the ASCII code of the input character. CHR returns the character whose ASCII code is the input inte

Processes that can be applied to data

Having looked at some forms of data, we now turn our attention to processes that can be applied to data. Each process that we consider in this section will input data of a specified form, and will result in a corresponding value. For example, one process, which we will call ASC, takes a character as input, and has as its resulting value the integer giving the ASCII code of the input character (as listed in Author(s): The Open University

3.4 Representing data in applications

Suppose that you are designing software for some application. You will be working with a programming language that enables you to communicate instructions to a computer. In this programming language, certain forms of data will already be represented electronically. These will include common forms of data, such as numbers, characters and sequences. In any particular application, you are likely also to be concerned with forms of data that are peculiar to that application. Having identified some

Learning outcomes

After studying this course, you should be able to:

  • understand ways in which data may be stored and processed

  • distinguish between different forms of data, and use notations introduced in the course to show different forms of data

  • appreciate that fine details may be important when interpreting formal notation (for example, different types of brackets may be used to distinguish between different forms of data)

  • interpret a given function
