The week ahead: Drawbridge dystopia
Protectionists stage protests across Germany. Andreas Kluth, our Berlin bureau chief, explains why anti-Americanism and a fear of globalisation are at the heart of the demonstrations. Also on the show: al-Qaeda's pragmatic comeback; and what are the odds that a party-less outsider could become France's next president? Helen Joyce hosts.

2.5 Public engagement

From the examples outlined in sections 2.2 to 2.4, which are just a fraction of what is available, you could conclude that the UK public are, in general, offered a wide range of science promotion events. These events provide valuable insights into many aspects of science for laypeople, perhaps especially the ‘high tech’ science that they might otherwise never experience. They also provide a useful opportunity for scientists to engage with the public – should that be wanted. And where th

2 Radiation from the galaxies

Stars occur in great collections called galaxies. The distribution and motion of galaxies provide us with the first important experimental information on which we shall build our understanding of the type of universe we inhabit. So, what do we know about galaxies?

All the stars that can be distinguished by the naked eye – a few thousand in number – belong to one galaxy: our own Milky Way Galaxy. Sometimes it is just written Galaxy, with a capital G, to distinguish it from all

6.1 Toughing it out

For small insectivorous mammals, the best solution to the problem of obtaining sufficient energy for their requirements, notably the maintenance of body temperature, is to feed continuously. But in temperate regions, insect eaters have to cope with shortage of insects during cold winters. In Section 6 I want to focus on two strategies that insect eaters use to cope with problems of overwintering.

3.9 Moon41: Apollo 15 station 2

The panorama was collected by James B. Irwin at Station 2. David Scott is to the left of the rover. He is examining a boulder. The large hill to the left of the rover is the summit of Mt. Hadley Delta. (QuickTime, 400KB, note: this may take some time to download depending on your connection speed)

4.6 Agency explanations: rational choice theory

The work of the Chicago School, despite the potential pitfalls of participant observation, does demonstrate that if you want to know why people commit crimes it makes sense to ask them. In his memoir of a criminal career in the early twentieth century entitled Jail Journey, Jim Phelan wrote:

The robber is a tradesman who, from economics or other motivation, chooses a trade with greater rewards and dangers th

Integrating Financial Stability and Monetary Policy Analysis [Audio]
Speaker(s): Oystein Olsen, Dr Sushil Wadhwani | The past decade shows how monetary policy and financial stability are interlinked. In recent years, Norges Bank has been one of few central banks where the risk of a build-up of financial imbalances has played an explicit role in monetary policy. Norges Bank was also one of the first to establish an analytical framework for the Basel III macroprudential countercyclical capital buffer. The Governor, Øystein Olsen, will discuss both analytical and o

Neuron Creations
Developed for third grade. Students will begin by being given a mini-lesson on the neuron itself. Then, in the actual activity, students will discover a fun, hands-on project where they learn about the neuron, an essential part of the human body. Each student will be given a piece of clay with which they will be able to form their own neuron. After they have created a neuron, the teacher will guide the students in labeling the various parts of the neuron as well as teach about each individual fu

Enabling Students to Construct Theories of Collaborative Inquiry and Reflective Learning: Computer S
To develop lifelong learning skills, we argue that students need to learn how to learn via inquiry and understand the sociocognitive and metacognitive processes that are involved. We illustrate how software could play a central role in enabling students to develop such expertise. Our hypothesis is that sociocognitive systems, such as those needed for collaborative inquiry and reflective learning, can best be understood as a community of interacting agents, who each have expertise in accomplishin

A Comparison of Model-Tracing and Constraint-Based Intelligent Tutoring Paradigms
Two approaches to building intelligent tutoring systems are the well-established model-tracing paradigm and the relatively newer constraint-based paradigm. Proponents of the constraint-based paradigm claim that it affords performance at levels comparable to that of model-tracing tutors, but with significantly less development effort. We have built both a model-tracing and constraint-based tutor for the same problem domain (statistical hypothesis testing) and report on our findings with the goals

Effects of pictures, age and experience on learning to use a computer program
This study examines the effects of pictures of screen captures and input devices on documentation for older novices. There was no main effect of pictures, but there were statistically significant interactions between the type of picture and the factors of age and computer experience. As predicted, the most optimized designs—the ones presenting screen captures—moderated the negative effects of age. We argue that screen captures help reduce two problems in the cognitive area that are especially
