As you use number skills in your work, refer back to the outcomes you hope to achieve and the goals you have set yourself. Ask yourself questions such as:

• am I on track to achieve my outcomes?

• what difficulties in using numerical or mathematical techniques have I experienced and what have I done about them?

• how have the choices and decisions I made impacted on the quality of my work?

• do I need to make

Care is needed at all stages of life. This unit makes care in the family its focus because the overwhelming majority of care, including health care, is supplied in families, much of it in private, much of it unnoticed and unremarked upon. The meaning of the term (informal carer) and the word (care) itself are explored.

This material is from our archive and is an adapted extract from Understanding Health and Social Care (K100) which is no longer taught by The Open University. If y

• Converging lenses or mirrors cause parallel beams of light to be brought to a focus at the focal point, situated at a distance of one focal length beyond the lens or one focal length in front of the mirror. Diverging lenses or mirrors cause parallel beams of light to diverge as if emanating from the focal point of the lens or mirror. Light paths are reversible, so a converging lens or mirror may also act as a collimator and

Most underground and some surface mines lie well below the water table. Both therefore have the potential to pollute any groundwater that flows through them. The root cause of the problem is the action of aerobic bacteria on pyrite (FeS2) within the coal sequence. This process releases metal and sulphate ions into solution, which in turn causes the acidity of the mine water to increase:

Fur is important in thermoregulation, but a conspicuous coat may proclaim sexual dominance or warn off competitors. It's similarly important for predators to remain unseen for as long as possible. The most familiar type of camouflage is the colour of the hunter merging into the background environment colour - think about stoat in winter (ermine), polar bears against the ice of the Arctic and lions against the baked soil and dried grass of Africa. But equally important is the patterned fur of

Rollback takes on both liberal and conservative conventions and their habits of mind. The objective of the work is dramatically ambitious. Woods writes with relentless precision, like an intellectual surgeon, to convince the reader that the government is not what it says (the source of security, prosperity, peace, justice, health) it is but is rather the opposite and thereby we can and should do without it precisely in the name of promoting security, prosperity, peace justice, and health.

The philosopher John Locke made the assertion that individual identity is inextricably linked to memory â€“ we are only what we remember being. Memory is a central part of how we think of ourselves, and indeed a central strand of what we might know. Memory is not simply a mechanical process. It works in various ways and you will use it in various ways in your writing. If you study A215 Creative writing, the Open University course from which this course was extracted, you will have the

Feedback can be an important aspect of improving your performance, but it can also have a negative effect if you take it too personally or if the giver is not skilled in offering feedback in a positive and constructive way. Feedback should not just be a matter of pointing out what you have done wrong; it should help confirm what you are doing well and give you pointers as to how you might improve in other areas. One important thing to remember when dealing with feedback is that the giver is c

• The common-sense narratives of the crime problem in the UK can be broken down into a series of distinct claims that make assessing them easier.

• Those claims can be tested against quantitative and qualitative evidence. Both types of evidence suggest that the narrative of change from a secure to an insecure society is at best partial, overestimating the tranquillity of the past, and the uncertainty and riskiness of the present.

We can trace the inheritance of characters in animals and plants by following the phenotype from generation to generation, in breeding experiments. We will describe work with maize (Zea mays), alternatively called corn (sweetcorn, or corn on the cob), which occurs throughout the world as an extremely important commercial crop plant, and which is used extensively in genetic research. We can also study the inheritance of characters at the level of the genotype. In this section we will ju

Samuel Orton was one of the earliest and most influential researchers into dyslexia, although he used the term strephosymbolia â€“ literally meaning â€˜twisted symbolsâ€™. He noticed that children with specific reading difficulties often wrote letters back to front, confused letters such as â€˜bâ€™ and â€˜dâ€™, and would swap the position of letters within a word during spelling (e.g. â€˜wasâ€™ might be written â€˜sawâ€™). From these and other observations, he suggested that their read
