1.1.3 Searching for information on maths and statistics

How well does the following statement match what you do when you begin a new search for information?

Before I begin a new search for information (maybe for an assignment, or to help you choose your next holiday destination), I spend some time thinking about what I already know, what the gaps in my knowledge are, and the best types of information to meet my needs.

Season 3 – Lesson 29 – Coffee Break Spanish
Coming up in this episode:

In this week’s episode, Alba and Mark are en la cocina, making a Spanish tortilla. The episode is slightly different from our usual episodes as the audio was recorded live in the kitchen rather than in the studio. There’s no “Act II” this week as the conversation follows the entire process of making the tortilla.

Please note that lesson 29 of Season 3 was originally known as lesson 329 of Coffee Break Spanish. We have renumbered

5.8 Dominant design

In most examples of evolving technological innovation there is a period when rival designs are competing to outperform each other, both in what they do and how well they appeal to the consumer. Certain features of a product or process come to be recognised as meeting key needs and they are incorporated in subsequent improved versions of the design. Other features might meet too narrow a set of needs to be economical and are dropped.

Gradually what emerges is a dominant design, wh

2.3 A closer look at ethical issues

Science can define what is practicable, what can be done, but it cannot determine which developments it is right to pursue; this is largely an ethical judgement. One sensible approach in making an ethical assessment is to try to weigh up the benefits of a technology against its potential to do harm. Deciding whether GM technology is acceptable, in ethical terms, then involves a judgement about the plausibility and moral weight of competing sets of claims. Individuals may make widely different

6.8 Sharing behaviour between use cases

For each use case there may be more than one scenario. In the process of requirements elicitation and specification, you may find a certain amount of common behaviour in two or more of your use cases. You may even find that an existing component can provide part or all of that common or shared behaviour. Indeed, if you do find such an existing component, this is an example of reusing requirements which is discussed more fully in MRP.

You can record the shared behaviour in

  • EMU has been accompanied by fiscal rules embodied in the SGP.

  • An issue raised by this is the compatibility of a common single monetary policy target designed to defeat inflation with different fiscal policies ostensibly at the discretion of the individual govern ments.

  • When France and Germany contravened the SGP fiscal rule, it was effectively suspended and broke down. This was a case of the Council of Ministers asserting c

Introduction

Anti-social behaviour, homelessness, drugs, metal illness: all problems in today’s society. But what makes a problem social? This unit will help you to discover how these issues are identified, defined, given meaning and acted upon. You will also look at the conflicts within social science in this area.

This material is from our archive and is an adapted extract from Social Policy: Welfare, Power and Diversity (D218) which is no longer taught by The Open University. If you want

2.3.1 Structural isomerism

In the saturated hydrocarbons, whose structural formulae are shown in Figure 16, it is not possible to form distinct isomers with just three or less carbon atoms linked together. There is only one way in which one carbon and four hydrogen atoms can be linked together, the single compound being methane, CH4. A simila

1 What are scattering and tunnelling?

The phenomenon of scattering was an important topic in physics long before the development of wave mechanics. In its most general sense, scattering is a process in which incident particles (or waves) are affected by interaction with some kind of target, quite possibly another particle (Figure 1). The interac

Their first main aim was to question local witnesses, including several who claimed to have seen the fall itself. One especially impressive eye witness was Alexander Maxwell, who lived on Magdalen Green, near the north end of the bridge. He was examined by Mr Trayner, counsel for the enquiry:

Stem Cell Therapies are no More Drugs Than Soufflés are Fast Food
Stemcell discoveries make great news stories, but their actual translation into routine clinical practice is still a major hurdle. Is it reasonable to expect the big pharmaceutical companies to manufacture these living therapies or is the paradigm shift from today’s drugs to ‘living cells as therapies’ overwhelming? Would McDonald’s ever put delicate soufflés on their fast-food menus? This lecture will use examples from current cell and tissue-engineered clinical therapies to illustrate

5.1 Reasons for unclear meaning

The meaning of law in a statute should be clear and explicit, but this is not always achieved. Thus, many of the cases which come before the courts concern a dispute over the meaning of a word or phrase in a statute. In those cases the task of the court is to decide the exact meaning of that particular word or phrase. There are a number of factors which can lead to an unclear meaning.

  • A broad term – There may be words designed to cover several

2.1 Planning your search

Your approach to searching will depend to a great extent on what kind of person you are. In an ideal world, when searching for information for a specific purpose, we would all find what exactly we were looking for at the first attempt, especially if we are in a hurry. However, it's always a good idea to have some kind of plan when you are searching for information, if only to help you plan your time and make sure you find the information you need.

2.8 Treatments for obesity

At this point you may be wondering what the range of studies that we have examined might suggest in terms of treatment for obesity. As you have seen, weight gain essentially arises from an imbalance of energy supply and energy expenditure. Therefore it is not surprising that dieting (restriction of energy input) and exercise (increased energy output) are recommended both to reduce body weight and also for their additional health benefits. However, even a quick survey of the research literatur
