The “Balance of Nature” Metaphor and Equilibrium in Population Ecology
I claim that the “balance of nature” metaphor is shorthand for a paradigmatic view of nature as a beneficent force. I trace the historical origins of this concept and demonstrate that it operates today in the discipline of population ecology. Although it might be suspected that this metaphor is a pre-theoretic description of the more precisely defined notion of equilibrium, I demonstrate that “...
متن کاملBridging Complexity and Ecology: An Outline of Health Ecology
Theoretical discoveries and practical insights of complexity science lead to a new understanding of health as a vital characteristic of the all-embracing web of life. The new concept of health ecology developed in this paper reveals delusions in the medical model of health currently used, and illuminates a way to health by continuously strengthening the self-healing capacity of nature and humans.

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...
15 صفحه اولThe rational design of biological complexity: a deceptive metaphor.
Biologists often claim that they follow a rational design strategy when their research is based on molecular knowledge of biological systems. This claim implies that their knowledge of the innumerable causal connections present in biological systems is sufficient to allow them to deduce and predict the outcome of their experimental interventions. The design metaphor is shown to originate in hum...
متن کاملPattern puzzle: a metaphor for visualizing software complexity measures
Software systems have become increasingly complex over the years. Complexity metrics measures software complexity using real numbers. It is, however, hard to gain insight into different complexities by looking at these numbers. In this paper, we present a software complexity metaphor that uses a jigsaw puzzle. In particular, each component of a software system is modelled as a piece of a jigsaw...
