Publishes essays and articles that report and interpret the results of original scientific research in basic and applied ecology.

This study shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to growing two or more crops together and how the approach can improve agricultural yields.

Now in its Third Edition, this text provides the background knowledge primary teachers need to plan effective programmes of work and answer children′s questions with confidence. The new edition links explanations of scientific concepts with children′s everyday experiences to help teachers and trainees foresee how they will present the subject knowledge to their pupils. Shaped by the National Curriculum, this text explains key scientific theories and concepts which pupils at primary level, including very able children, need in order to understand the observations and investigations they undertake. A CD ROM of 200 science investigations for young students is included with the new edition, allowing teachers to explore the practical application of topics covered in the book. This is an essential book for teachers, student teachers and anyone interested in the roots and growth of science education.

Identifies four 'worldviews' which approach agricultural ethics from different philosophical perspectives and examines current issues, such as the use of pesticides, from these perspectives thu s achieving a workable account of sustainability.

Only recently has the phenomenon of technology become an object of in terest for philosophers. The first attempts at a philosophy of technology date back scarcely a hundred years - a span of time extremely short when com pared with the antiquity of philosophical reflections on nature, science, and society. Over that hundred-year span, speculative, critical, and empiricist approaches of various sorts have been put forward. Nevertheless, even now there remains a broad gap between the importance of technology in the real world and the sparse number of philosophical works dedicated to the under standing of modern technology. As a result of the complex structure of modern technology, it can be dealt with in very different ways. These range from metaphysical exposition to efforts aimed at political consensus. Quite naturally, within such a broad range, certain national accents can be discovered-; they are shaped by a com mon language, accepted philosophical traditions, and concrete problems requiring consideration. Even so, the worldwide impact of technology, its penetration into all spheres of individual, social, and cultural life, together with the urgency of the problems raised in this context - all these demand a joint philosophical discussion that transcends the barriers of language and cultural differences. The papers printed here are intended to exemplify such an effort at culture-transcending philosophical discussion.
