5 Conclusion This chapter has enabled you to think about the essential role of technological change in determining economy-wide growth and the growth of firms and industries. We have seen that many issues surrounding the new economy are really issues around the dynamics of technological change: rapid increases in productivity, the emergence of many small firms, new products and new processes, and so on. The main lesson of the unit has been to provide a historical perspective to the introduction of new tec
How Does Your Mobile Phone Work?
For most of us, a mobile phone is a part of our lives, but I am sure your curious minds have always been struck by such questions as to how a mobile phone makes a call, and why there are different generations of mobile communications. Let’s explore the technology behind mobile (09:03)
2.2 Ice and salt As noted in Section 1.5, Europa's near-infrared reflectance spectrum was used as long ago as the 1950s to demonstrate that its surface is mostly water-ice. More recently, spectroscopic observations by the Hubble Space Telescope and Galileo have revealed some regions where the ice appears to be salty (see below) and ha
Legislative and Presidential Politics
Democracy entails a complicated process of dynamic interactions between diverse actors pursuing often-conflicting interests. Politics in a democratic system is thus naturally messy, complicated, and confusing. This is exemplified most clearly by the two national institutions, i.e., legislature and the Presidency.
5.2 The aims and principles of system engineering The aims of systems engineering can be divided into those to do with its outputs and those associated with the process itself. As far as its outputs are concerned, systems engineering aims to ensure that: the requirements of all the stakeholders are taken into account in engineering the system the system, as engineered and realised, meets the requirements of stakeholders the system, while meeting the req
Generative CAD Systems
In the new millennium, Computer Aided Design has emerged as the most potent technological innovation in design. As BIM promises to integrate design tasks vertically and horizontally through graceful data exchange, new frontiers appear to researchers and practitioners as potential watershed events of the next decade. Generative approaches, a venerable engagement of computational design, is emerging as one of these. The proceedings of the Generative CAD Symposium held at Carnegie Mellon University
1.3 Vitamin D The main role of vitamin D is to facilitate the uptake of calcium from food, through the lining of the small intestine into the blood. It also controls the deposition of calcium in the bones during growth and maintains adult bone structure. If vitamin D is deficient, with less calcium available, the skeleton fails to develop normally. The most obvious symptom is the bowing of the leg bones in children, producing the condition called rickets (Author(s):
Interview with Phyllis Reynolds Naylor (Part 5)
In this section, Phyllis Reynolds Naylor, winner of the ASPCA Roger Caras Award, answer the question, "How did you feel when you learned you won the ASPCA® Roger Caras Achievement Award?" She answered that the award is relatively new and she had to look it up to see what it was for. The award is for a person or organization that promotes animal welfare. She says getting the award was a thrill. (0:24)
2.1 Background to the idea of international rights The UN Charter and the Declaration form part of a post-Second World War international settlement which established, on the one side, the formal legitimating ideology of the international system, national self-determination and sovereign equality and, on the other, the ideology of universal human rights. The appeal of this set of claims was the hope that different peoples could live together in peace and security. It was an attempt to accommodate difference (through the idea of national self-d
Money talks: A peer-to-peer Ponzi scheme
Ponzi schemes abound in China and the latest has bilked nearly one million investors; and we also look at why negative interest rates have gone from being a European phenomenon to a global one
8.1 Making usable products This section reveals that many modern products need to usable by our minds as much as our bodies. Products need to be understandable, and present information and feedback in meaningful ways. A lot of ergonomics research is aimed at establishing guidelines, standards or rules that can be applied by designers in a variety of situations. Where this applies to the physical use of products, much of it is based on standard body measurements. These body measurements are known as anthropomet

10 User research techniques: observing users This section introduces an alternative to basing user research on yourself. This is observation of experienced and inexperienced users either in experimental or natural situations. One way around the difficulties of basing research on oneself is to observe other people acting as users and to choose naive or different kinds of experienced users, depending on what information you want to gather. Begin by identifying those experienced users who will be able to provide you with releva
Real Brazilian Conversations #5: Brazil’s political crisis, part 2 1.6.4 Blogs The founder ofTechnorati claims that the number of ‘blogs’doubles every five months and that the creation rate is approaching two per second. One estimate I read in July 2010 put the number at 400 million ‘blogs’. Because these online diaries offer instant publishing opportunities, you potentially have access to a wealth of knowledge from commentators and experts (if they blog) The sounds of German Business operations Design and Designing 1.3 Psychology has social impact The relevance of psychology to everyday concerns, and the ease with which it can be popularised and used, mean that psychological knowledge – some of it dubious, some of it accurate – is continually absorbed into culture and often incorporated into the very language we use. Examples of psychological concepts that have entered popular discourse include the notion that we are predisposed, both through evolution and through the functioning of our brains and nervous systems, to behave in cert

This module investigates the sounds of German and how they can be described accurately (“phonetics and phonology”). Students will learn to transcribe German using the notation of the International Phonetic Association, and we will look in particular at aspects of German pronunciation that are hard to master because they are different to English or similar to French. We will a

How do you start to design a product? Can drawing techniques be learned? And why is modelling such a useful technique? This album introduces the basic skills necessary to communicate ideas on paper, as well as revealing the step-by-step processes for making three-dimensional models of objects, showing perspective in drawings and sketching complex objects. It also features a case study of the Strida folding bicycle, an idea taken from initial drawings to marketed product. This material forms part
