7.3 Summary The idea of discourse alerts us to a number of issues about the social construction of social problems. It suggests that we need to look beyond competing theories or perspectives to look at how knowledge is organised around central themes that allow the different theories to compete. Discourses define what the problem is, and it is because theories share the definition of the problem that they can compete and argue. Perspectives that start somewhere else – or do not share the definition of

In 1998 Wakefield was the first to make the claim that autism and the MMR vaccine are linked.1 It is based on a dozen clinical cases of gastrointestinal disorders with w
7.4 Nuclear abundances as evidence for the big bang What we have seen is that a theoretical model based on the assumption that there was a big bang, and incorporating an assumption about the present-day value of the baryonic density, ρb,now, leads to definite predictions as to what the nuclear abundances must have been when the elements froze-out. This, therefore, provides us with a third way of checking out the big bang hypothesis: Do the present-day cosmic nuclear abundances agree with these predictions for any plausible v

1 Current imaging techniques A grainy Polaroid of the child in a mother's womb – an X-ray of a tibia fractured in a traffic accident – a report on a brain scan anxiously awaited. Very few of us have not had some connection with the techniques and practices of medical imaging. Often, these contacts are in periods of personal drama in which the medical images chart our physical status, the
management of a condition and, in some cases, our future. Imaging is a central feature of contemporary medicine. Along with c

It is best to start to settle on the aims and objectives/outcomes (these terms are variously used around the world but are largely interchangeable) of your free course as soon as possible. You looked at the intended learning outcomes of some courses in Section 1. The difference between aims and objectives is that the aim is the general statement of what you hope the course will achieve, usually expressed in terms of what you will be presenting in the course; the objectives are what you intend 7.5 Mind-maps Mind-mapping can be a particularly powerful visual tool for shaping thought. The basic principle here is to note down the central topic or idea in the centre of a piece of paper and work outwards adding the points which flow from and connect to it. It is particularly helpful for seeing the different levels of thought discussed above. Figure 2.5 Obesity and ageing So, it seems that a part of the explanation for Ron's obesity, and the health problems that have led him to seek medical advice, may relate to the environment in which he is living, and more specifically the diet that he has chosen. It may also be a diet that is especially effective in activating the reward circuits in Ron's brain. However, Ron is also in his later middle age. A longitudinal study of people of this age in the USA suggests that average body weight increases by 1–2 kg per dec 3.2 The evolution of the EU The EU has grown out of a series of intergovernmental political initiatives which have been expressed in a number of treaties. These treaties form the building blocks that give authority and power to the institutions and law-making bodies of the EU. The process is evolutionary, as treaties are reviewed and amended to reflect both the changing membership and the vision of the EU. The EU is founded on several treaties: The treaty that established t Food Scientists Make Smoother Ice Cream 7.2 Coding of information in the higher auditory centres We have seen that in the cochlear nerve, information about sound intensity is coded for in two ways: the firing rates of neurons and the number of neurons active. These two mechanisms of coding signal intensity are found throughout the auditory pathway and are believed to be the neural correlates of perceived loudness. The tonotopic organisation of the auditory nerve is also preserved throughout the auditory pathway; there are tonotopic maps within each of the auditory nerve relay nuclei, the Let's Improvise Together 4.13.3 Scrutiny Again, connected to the accountability issue is the problem of adequate scrutiny. The detailed, technical and specific nature of much-delegated legislation means that, on the whole, Members of Parliament (the elected representatives) do not have the expertise to consider proposed legislation effectively. In addition, you have already noted that the scrutiny committees themselves only have limited powers. 3.4 Specialisation within language areas: brain scanning Is there any evidence from the undamaged brain that the view derived from aphasia is indeed correct? The most useful methodologies here use either PET or functional MRI (fMRI) scanning to establish which parts of the brain are active in particular tasks. The difficulty is that a standard linguistic task, such as understanding a sentence's meaning, involves phonology and syntax and semantics, and thus is not helpful when trying to tease out which of these subtasks happens in which areas. Radio Lingua Network News: 26 September 2008 2.1 Introduction The unique climate and topography of each desert links to the unique and characteristic flora and fauna found there. From the brief description of deserts provided in Section 1, you can appreciate that a desert provides a variety of niches for animals and plants. The term ‘niche’ applied to animals describes its role in a particular environment, and includes a number of characteristics such as habitat range, how the animal feeds, its diet, its environmental requirements and also its preda Acknowledgements The content acknowledged below is Proprietary (see terms and conditions) and is used under licence.

Food chemists add a tasteless edible protein called gelatin hydrolysate to ice cream find that it keeps ice crystals small, resulting in a smoother, more pleasing product. The protein inhibits the growth of ice crystals, keeping them small and preserving the creamy texture of ice cream. (1:33)
The creators of ?Let's-Improvise-Together? adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ?Let's Improvise Together? has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance
