APPLICATION OF FULL-SCALE MODELLING IN VIETNAM: AN OUTLINE FOR DISCUSSION
This paper discusses the possibility of applying full-scale modelling in Vietnam, a non-western so called developing country. It deals with two main questions: 1) Is the application of full-scale modelling to be restricted to the West only? 2) what are the possibilities, constraints and fields of application - with attention to the methodological validity and technical solution for full-scale modelling in Vietnam? It is argued that since full-scale modelling is based on people-environment intera

Introduction

This unit draws attention to the value of a sociocultural understanding of spoken language in the processes of teaching and learning. It focuses upon how language can be used for persuasion, control and argument, and how dialogue can act as an aid to development. Along with some background reading and activities this unit offers opportunities for the evaluation of some selected classroom talk.

Medical statistics
This free course is concerned with some of the statistical methods used in epidemiology and more widely in medical statistics. Section 1 introduces cohort studies in which individuals are classified according to their exposure and followed forward in time to evaluate disease outcomes. Section 2 looks at models for cohort studies. Section 3 introduces case-control studies in which individuals are selected according to their disease status and past exposures are then ascertained. Section 4 covers

The rise of shareholder activism
Julian Franks, Professor of Finance, shares his view that increasing shareholder activism is a positive development and predicts that the future will see stronger owners and hopefully managers who have learnt how to engage with these owners.

Green Games Build Eco-Awareness
UMass Amherst staff and students held the first Green Games sustainability competition involving hundreds of students in 23 residence halls. Teams earned points by attracting "likes" to videos on Facebook, for example, or getting fellow residents to attend films and lectures, reset laptops to low-energy mode, recycle used batteries and broken electronics, or tap into a water-conserving shorter shower competition. The winning team was the Orchard Hill residential area.

1.1 They think it's all over

They think it's all over … it is now!

(Kenneth Wolstenholme, 1966)

This is one of those iconic sporting media moments. It happened a long time ago, when Geoff Hurst's third goal in the dying seconds of extra time clinched England's 4–2 win over Germany in the 1966 football World Cup final. People who were not even born, let alone at Wembley or watching the game on television, still reco

1.5 Obesity treatment

Obesity treatment is only successful if weight is reduced and maintained to within a desired range. There are three approaches to obesity treatment: changing behaviour and diet is the most common approach although drugs and surgery can be used in some severe cases of obesity.

Behaviour and diet: it is important to be realistic about an obese patient's target weight as many patients have over-ambitious targets that they are unlikely to achieve. A severely obese patient probably ca

Multimodal representations of architectural design knowledge: Interaction between visual and ontolog
This paper presents multimodal representation of architectural design knowledge, where explicit and implicit information are linked. The aim is to develop computational environment that combines several modes of representation. Integration of interactive digital-models library and ontological model of architectural design factors is investigated.

4.2.1 Comparing the management systems

One approach to BS 8800 follows the ISO 14001 model, and the ISO 14001 system itself was closely modelled on the previous ISO 9000, with the 2000 revision of ISO 9000 following ISO 14001 principles. As a result, you may imagine that there are similarities between the standards. Many of the elements are similar, and some are nearly identical. Management systems share common elements, including developing and documenting procedures, training, record keeping, auditing, and corrective action. Fig

2.3 Contingent model of accounting change

The totality of the accounting rules in any one country at any one time represents an accumulation of rules that have been brought in over many years (even centuries, in the French case). In remembering that, it becomes clear why the rules are sometimes inconsistent: they have been put together by different people, at different times, and in the face of different circumstances and priorities. It also makes clear why it would be optimistic to expect close comparability between national sets of

3.1 Introduction

Generally, when we talk about communication between humans, we mean one person conveying information to another person. Figure 6 shows a basic model, or representation, of a communication system for getting a message from the sender to the recipient. The diagram shows the sender (User

EN-9. The urban biodiversity (Vidéo)

With Nathalie Machon, we will discover the urban biodiversity. She proposes a zoning of cities depending on the extent of the green areas, then she explains the ecological features specific to this environment. She concludes with an overview of the different groups of species we can observe in town.

1.3 Managing the national economy

The earliest regulation in Europe was not motivated by stewardship concerns, but was aimed at small businesses whose owners did not take the trouble to measure the success of their business. Consequently they went into liquidation, often, as is the case with small business networks, taking other businesses down with them. The 1673 Savary Ordonnance in France, which is regarded as the first national accounting rule created in the world and was subsequently taken up into the French Comme

2.10 The distribution of repeated measurements

As noted in the previous section, if the same quantity is measured repeatedly, the results will generally be scattered across a range of values. This is perhaps best illustrated using a real example. Table 2 shows 10 measurements of a quantity called the 'unit cell constant' for an industrial catalyst used in the refining of petrol; this is an important quantity which determines how well the catalyst works, and can be measured by X-ray diffraction techniques. Notice that the cell constant is
