1 Children's rights: general issues

The audio file in this unit considers the general issues of children's rights, and the possibilities and implications of imagining children as citizens. Within the discussion, ideas about childhood and children's needs are explored. Although the programme focuses specifically on children it is possible to link to the wider issue of social construction of difference and power. Some examples are given in these notes.

This audio file was recorded in 1998 and related to a TV programme on ch

4.7 Summary

  • Piaget proposed that all children pass through an ordered sequence of stages of cognitive development. This development arises through the processes of intrinsic motivation, assimilation and accommodation and equilibriation.

  • Children's actions on the environment are the basic building blocks of development.

  • Piaget argued that children reason differently to adults, as their mental representations of the world are initially c

4.4.3 Buffer strips

The interface between aquatic ecosystems and the land is an ecotone that has a profound influence on the movement of water and water-borne contaminants. Vegetation adjacent to streams and water bodies can help to safeguard water quality, particularly in agricultural landscapes. Buffer strips are used to reduce the amounts of nutrients reaching water bodies from runoff or leaching. They usually take the form of vegetated strips of land alongside water bodies: grassland, woodland and wet

6 Summary

Solar power is an immense source of directly useable energy and ultimately creates other energy resources: biomass, wind, hydropower and wave energy.

Most of the Earth's surface receives sufficient solar energy to permit low-grade heating of water and buildings, although there are large variations with latitude and season. At low latitudes, simple mirror devices can concentrate solar energy sufficiently for cooking and even for driving steam turbines.

4.1 Introduction

Nuclear power generation involves concentrated fissionable fuels which, after fission, leave significant quantities of fission-product isotopes, some of which are highly radioactive. Much of the criticism levelled against the industry falls under four main headings to which we have alluded in preceding sections:

  1. the operational safety of nuclear reactors;

  2. the biological effects of abnormal radiation levels arising from fuel transport,

2.6 Transcytosis

The components of the endocytotic pathways also function to transfer material within a cell. In vertebrates, most cells depend on nutrients from the blood even though they are not in direct contact with the blood. Diffusion of molecules from the blood to the tissues would in many cases be just too slow. Transcytosis is the transfer of molecules across cells from one side to the other, a process that entails endocytosis, vesicular transfer and exocytosis, and which speeds the bulk movem

1.4 Specialised intermediate filaments

Compared with other cytoskeletal elements, intermediate filaments are more like a fixed scaffolding for the cell. They have a higher tensile strength than microtubules and microfilaments. Consequently they contribute greatly to the overall integrity of the cell and preservation of its shape. Not all eukaryotic cells have cytoskeletal intermediate filaments, and of those that do, each cell type has its own distinct set of intermediate filaments. The intermediate filaments, being cell-type spec
