Introduction

This unit focuses on the problem of greenhouse gas emissions, especially carbon dioxide, and explore what you can do to lighten those emissions to help reduce the rate of climate change. You will assess your ‘carbon footprint’ and see what actions you and, if relevant, other household members could take to lighten that footprint. You will also better understand which actions are more and less effective, and the scope and limits of what individuals can do at the personal and household

5 Nuclear energy
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This unit provides background information to each resource, so that you can assess them for yourself.

4.13.1 Democratic accountability

The main criticism of delegated legislation is that it takes law making away from the democratically elected House of Commons. Instead, power to make law is given to unelected civil servants and experts working under the supervision of a Government minister.

Iran: War or Peace?
The Bush administration’s panic about failing in Iraq is now driving its fierce attitude toward Iran, according to Kenneth Pollack. President Bush’s 2007 State of the Union message hinted at exercising military force to deal with an Iran it accused of stoking up insurgency in Iraq. Pollack points out that historically

2.5 Visual communication

As discussed in Reading 2.4, written text has major limitations in representing relationships between things when they do not follow the linear structure of the text. Relationships can be extremely complex, even circular, as you will see in this block. In particular, the linear sequence of text is not able to clearly show context, elements, structure, processes and functions of Author(s): No creator set

As discussed in Reading 1.6, the behaviour of all living organisms that determines their resource use is mostly controlled by a set of models encoded in their genetic material. Most significant changes in the behaviour of a particular species of Author(s): No creator set

4.11.1 Debating and negotiating meaning

The two briefings in Boxes 4.10 and 4.11 illustrate other technological approaches to supporting socially based forms of knowledge generation, with the common theme of facilitating negotiation and debate among stakeholders. These are examples of tools which can assist communication between communities of practice as they seek to understand each other's perspectives.

4.8.1 Capturing meetings

Internet meetings and broadcasts can be easily recorded and replayed because everything is mediated digitally: the text of emails, the audio stream and the slides used. However, face-to-face meetings are by far still the most common way to present and discuss issues in organisations, and the richness of personal presence makes them unlikely to disappear. How can face-to-face meetings be ‘captured’? Traditional written minutes provide a rough summary of points discussed, but provide o

Population Growth in Yeasts
This lesson is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arose during the first lesson and its associated activity, in this lesson students work in small groups to design experiments that will determine how environmental factors affect yeast population growth.

1.1 Supporting the professionals

To gain a better understanding of the teaching assistant's role, it is helpful to consider the ways in which different kinds of professionals are supported by paraprofessionals. Just as there are teaching assistants in schools, there are equivalent roles in other areas of work. For instance, in the health service the work of nurses is supported by ‘health care assistants’, and in social work ‘personal assistants’ provide support to children in care (‘looked-after chil

Racing with the Sun - Creating a Solar Car
Students use engineering design principles to construct and test a fully solar powered car. Several options exist, though we recommend the "Junior Solar Sprint" (JSS) Car Kits that can be purchased with direction from the federal government. Using the JSS kit from Solar World, students were provided with a photovoltaic panel that produces ~3V at ~3W. An optional accessory kit also available from Solar World includes wheels, axles and drive gears. A chassis must be built additionally. Balsa wood

1.4.4 Case study 1: Vic Harris – a hospital death

Vic was a 68-year-old man with a long history of chronic (pulmonary) obstructive airways disease and was therefore a regular in-patient at the medical ward of the local hospital where he received treatment. Vic had been on Crawford Ward for two weeks and was feeling very concerned that he was not making any progress. Previously he had experienced quite a marked improvement after a few days’ treatment but this time, instead of improving, his breathlessness and lethargy were getting worse and

3.6 Different paradigms and different methods

These different methods alert us to the fact that psychology is not just one enterprise, but a series of interlocking enterprises in which psychologists have different views about the best ways to try to understand or explain people and their behaviour and experience. These are arguments about epistemology; that is, what questions to ask, what sort of evidence to look for, what sort of criteria to use to evaluate explanations, and what sort of methods to use.
