Trainiere dein Hörverstehen mit den Nachrichten der Deutschen Welle von Donnerstag – als Text und als verständlich gesprochene Audio-Datei. *** Bundesjustizministerin Sabine Leutheusser-Schnarrenberger hat der Türkei rechtsstaatliche Defizite vorgeworfen. So gebe es Massenprozesse gegen Anwälte und Journalisten, sagte Leutheusser-Schnarrenberger der "Passauer Neuen Presse". Problematisch sei auch die teilweise überlange Dauer der Untersuchungshaft. Dennoch sprach sich die FDP-Politiker

Session 1: Monitoring online student activity and engagement

Purpose/Aim of this session

One of the foundations of a learning community is active learners. Student engagement is also important for the tutor and peer feedback and assessment process.  If students aren't engaging with their community of learners, or posting their work and/or commentary, there will be very little for you to assess.

An Afternoon with Gronk at Otis
Gronk (born 1957 in East Los Angeles, California, USA) is the artistic name of Chicano painter, printmaker, and performance artist Glugio Nicandro. "Gronk" is a name his mother found in an article on a Brazilian tribe in National Geographic. Gronk was a founding member of ASCO, a multi-media arts collective in the 1970s. Influenced by European film, existentialism, and literature (i.e., Camus, Beckett) Gronk and his early teenage cohorts made "movies without film", farcical "happenings" on the

Complex numbers
You may have met complex numbers before, but not had experience in manipulating them. This unit gives an accessible introduction to complex numbers, which are very important in science and technology, as well as mathematics. The unit includes definitions, concepts and techniques which will be very helpful and interesting to a wide variety of people with a reasonable background in algebra and trigonometry.Author(s): Creator not set

4.3 Least Upper Bound Property

In the examples just given, it was straightforward to guess the values of sup E and inf E. Sometimes, however, this is not the case. For example, if then it can be shown that E is bounded above by 3, but it is not so easy to guess the least upper bound of E.

In such cases, it i

6.2 Getting the feel of big and small numbers

Very small and very large numbers can be difficult to comprehend. Nothing in our everyday experience helps us to get a good feel for them. For example numbers such as 1099 are so big that if Figure 1 was drawn to scale, you would be dealing with enormous distances. How big is big?

First express 1 000 000 000 in scientific notation as 109. Next, to find out how many times bigger 1099 is, use your calculator to divide 1099 by 109

1.2 A framing paradox: experiencing nature with cognitive tools

Whilst language tools are helpful in conveying meaning in conversation amongst humans, establishing what matters in ‘conversation’ between human and non-human nature, or amongst non-human living entities, requires different cognitive tools. Cognition refers to the way in which external information from the environment is processed. As sentient beings, humans and some other animals are able to experience wellbeing and suffering. In the next reading, Ronald Moore examines how we engage with

6.1 Introduction

So far, we have briefly introduced three key approaches to improving the sustainability of human energy use in the future. These are:

  • (a) ‘cleaning-up’ fossil and nuclear technologies;

  • (b) switching to renewable energy sources;

  • (c) using energy more efficiently.

5.2 New Zealand's changing environment

In this study I want to explore some possible effects of this new trade on the environment of one of the countries involved. I've chosen New Zealand, partly because the developments we have just been discussing happened only a few decades after the first large-scale settlements of Europeans, and had a strong influence on the direction of its economy. Some background information will help to set the scene.

New Zealand consists of two mountainous islands with a total area similar to that

4.3 Dilemmas of climate change

In Section 4.1, we looked at claims that climatic change thousands of years ago triggered the movement of people into the ocean, eventually leading to the settling of islands like Tuvalu. We have also seen that these islands only rose out of the ocean because of dynamic geological processes coupled with dramatic changes i
