3.3.1 Ethylene, propylene and butadiene

Nowadays ethylene is the most important building block for the chemical industry, particularly as a monomer in its own right, as a co-monomer with other vinyls, and as a source of vinyl monomers. It is the prime source for ethylene oxide, which is another major source of polymers, glycols and ethers. They can also be used to build up more complex C4 molecules and aromatics.

Some of the ways in which the ethylene molecule is modified to create other chemicals and polymers are

Knowledge workers and the need for 'seduction'
Knowledge workers of the future may not respond to traditional management models of 'command and control', says Professor Arnoud De Meyer, Director of Cambridge Judge Business School. Instead, they need to be seduced! His 'Collaborative Leadership' model supports the use of 'communities' of people 'co-acting' without hierarchy to successfully solve the complex and interconnected problems the world faces.

Pablo Garcia - A Brief History of Drawing Machines, Since 1425
Mechanized drawing existed long before computers. Methods for automating drawing—especially drawing from life—appeared simultaneously with the earliest descriptions of constructing linear perspective. What does this long quest for computed drawing tell us about our relationship with technology? What does this mean for the presumed novelty of the computer? What does it mean to be "virtual"? ___ Pablo Garcia is Assistant Professor in the Department of Contemporary Practices at the School of

1.1 Understanding scale diagrams

Plans of houses and instructions for assembling shelves, etc., often come in the form of scale diagrams. Each length on the diagram represents a length relating to the real house, the real shelves, etc. Often a scale is given on the diagram so that you can see which length on the diagram represents a standard length, such as a metre, on the real object. This length always represents the same standard length, wherever it is on the diagram and in whatever direction.

1.9 Community and identity

In an Italian exhibition of cartoons on the theme of globalization (reported in the Financial Times (Lloyd, 2000)), one depicted two women sitting on a couch. The first woman explains enthusiastically ‘Thanks to globalisation, we know immediately what's happening all over the planet!’; the other, crying, says ‘I just want the gossip from next door!’ This was interpreted as a longing for a previous era of emotionally and physically closer communities. The reality of such ‘good

Everything from Oil to Silver: Are Speculators Causing Too Much Volatility?
Allegations that traders manipulated oil prices in 2008 are reinforcing the buzz -- at the gas pump and elsewhere -- that speculators are driving up the price of oil, triggering wild price spikes and nail-biting volatility. Fingering speculators is a popular pastime these days, but experts at Wharton and elsewhere say the blame is often misplaced. Although speculation can affect prices, most of the recent price swings in oil and other commodities are happening for fundamental economic reasons.

A Recession for Perks? What Companies Offer and What Employees Want
Until recently, most discussions of perks focused on what high-tech companies in Silicon Valley were offering their employees, from free gourmet meals and yoga classes to massage therapy and auto detailing. But these days, many companies are simultaneously trying to shake off the recession, keep costs low, retain valued employees and recruit talented new ones. Perks, if designed well, can help achieve these goals. Author(s): Knowledge@Wharton

9.5 Social work and the law in Scotland

In this unit you will be asked to reflect on the meanings of both social work and law. You will find that these concepts are open to a range of possible definitions, and that the functions of social work and law can change depending on the practice context. Their meaning is also affected by the perspective from which they are viewed, for example, the service user's experience of social work and law will not always match the expectations of the professional, or the perceptions of the general p
