4.7 Summary

Water in its 'natural' state supports a complex, yet fragile, ecosystem. The ability of natural watercourses to sustain aquatic life depends on a variety of physical, chemical and biological conditions. Biodegradable compounds, nutrients and dissolved oxygen must be available for the metabolic activities of the algae, fungi, bacteria and protozoa which are at the lowest level of the food chain. In addition, plant and animal growth cannot occur outside narrow ranges of temperature and pH. Susp

Social work learning practice
This free audio course, Social work learning practice, focuses on the importance of people's backgrounds and experiences in the field of social work. It identifies the diverse ways in which service users and social workers define themselves, helping you to understand how the two groups perceive each other and relate successfully to each other. An understanding of how people make sense of their experiences will help you to define yourself, and your own place within the process.Author(s): Creator not set

3.4.3 Respecting autonomy is the foremost ethical principle in health care

Some commentators believe the pendulum has swung so far in favour of respecting autonomy that it leaves little scope for users to be passive recipients of healing. The desire to make each user an active participant in their own healing process can make it hard, or even impossible, for a user to refuse to engage in active decision making, and leave the decision to the benevolent practitioner. In this case, the user may waive his or her rights, by choosing not to be kept informed about changes

Managing Creativity and Creative Management
As the Creative Industries become a more important part of the global economy does the stereotype of the creative genius still persist? Do we need to rethink our ideas on creativity and understand how it works more clearly? Dr Chris Bilton, Centre for Cultural Policy Studies, argues that organisations need to start thinking about creativity as a process and begin adapting traditional business strategies to develop a creative approach to management.

Smelling and Tasting
If you can't smell, you probably can't taste very well either. They are closely-related functions. Receptor cells for taste and smell are located in the mouth and nose, respectively. As the receptor cells are stimulated, they send impulses from these organs to the brain's smelling and tasting centers, the cortices. For taste, impulses stimulated by the chemical compounds in food are sent to the gustatory cortex. For smells impulses stimulated by the chemical compounds in odors are sent to the ol

1.2.4 Surgical methods of contraception

Surgical methods are by and large the most drastic and irreversible ones, ranging from castration to relatively untraumatic tube-tying. Because of the psychological and physiological side-effects, surgical removal of the testes or ovaries is not generally carried out for contraceptive reasons alone, although these operations may be carried out for other reasons, such as the presence of malignant tumours. Any kind of surgical sterilization can be physiologically traumatic for a woman, as it in
