5.3 Global warming
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef

3.2 By medium

We can divide texts up by the medium in which they appear. This is a broad division that is technologically based. It may seem excessively obvious, but it can be quite revealing. For example, different media have different periodicities (frequency of appearances) – most magazines appear weekly or monthly, while newspapers are weekly or daily. Episodes of television programmes are most commonly also weekly or daily, but films appear on a different basis altogether, since, like books or CDs t

1 Introduction and overview

This unit is concerned with the very things that we, as ordinary people, talk about as a consequence of listening to radio, watching television or reading newspapers and magazines: the programmes and articles that constitute media output. We do not (except on rare occasions) experience celebrities face-to-face, as their celebrity is conditional on having their image disseminated far and wide. This unit examines the everyday evidence of celebrity activity – what academic media analyst

Handbook for Teachers of Multi-Grade Classes: Improving Performance at the Primary Level
Multi-grade classes and single teacher schools have made it possible for many children in remote rural areas and communities to access education. However, the teachers teaching in these environments rarely receive training in how to deal with and manage the large numbers of pupils, of different ages and levels of learning, that they confront in their classes. These tools can assist teachers in this regard. This handbook comprises ten units, each one consisting of common experiences, case studies

Aerosols and Warming Change with Time: Version 2
As the aerosol content and solar heating change with time, the atmosphere and the Earths surface experience different warming and cooling. This animation displays a time series of the INDOEX region with 8-day averages showing aerosol and solar reflectance (albedo) data from the Terra satellite. From these, we see how these inputs generate warming of the atmosphere (Atmospheric Forcing - red regions) and cooling of the surface (Surface Forcing - dark regions). Areas of missing data (due to clouds

9 Sedimentation at the end of the Caledonian Orgeny; Section 10 Legacy
Some of Britain’s most dramatic scenery is to be found in the Scottish Highlands. The sight of mighty Ben Nevis, the desolate plateau of the Cairngorms, or the imposing landscapes of Glen Coe can unleash the call of the wild in all of us. Although these landforms were largely carved by glacial activity that ended some 10,000 years ago, the rocks themselves tell of a much older history. The Highlands are merely eroded stumps of a much higher range of ancient mountains. This unit is an account o
