In the final analysis, sustainable agriculture must derive from applied ecology, especially the principle of the regulation of the abundance and distribution of species (and, secondarily, their activities) in space and time. Interspecific competition in natural ecosystems has its counterparts in agriculture, designed to divert greater amounts of energy, nutrients, and water into crops. Whereas natural ecosystems select for a diversity of species in communities, recent agriculture has minimized diversity in favour of vulnerable monocultures. Such systems show intrinsically less stability (...) and resilience to perturbations. Some kinds of crop rotation resemble ecological succession in that one crop prepares the land for successive crop production. Such rotations enhance soil organic processes such as decomposition and material cycling, build a nutrient capital to sustain later crop growth, and reduce the intensity of pest buildup. Species in natural communities occur at discrete points along the r-K continuum of reproductive maturity. Clearing forested land for agriculture, rotational burning practices, and replacing perennial grassland communities by cereal monocultures moves the agricultural community towards the r extreme. Plant breeders select for varieties which yield at an earlier age and lower plant biomass, effectively moving a variety towards the r type. Features of more natural landscapes, such as hedgerows, may act as physical and biological adjuncts to agricultural production. They should exist as networks in agricultural lands to be most effective. Soil is of major importance in agroecosystems, and maintaining, deliberately, its vitality and resilience to agricultural perturbations is the very basis of sustainable land use. (shrink)

This is a study of how self-transformation may occur through the practice of reframing one's personal experience in terms of a canonical language: that is, a system of symbols that purports to explain something about human beings and the universe they live in. The Christian conversion narrative is used as the primary example here, but the approach used in this book also illuminates other practices such as psychotherapy in which people deal with emotional conflict through language.

A sceptical response to the idea that wisdom may be turned into a new academic subject or science, and to the idea that to do so would be in any way be wise. .

This study identifies and describes the values espoused by the 62 companies that have consistently appeared on the “Fortune 100 Best Companies to Work For” list. We identify 24 separate values and offer an analysis of the keywords and phrases used to promote them. We confirm that these values fall within the categories of four well-accepted theoretical frameworks of corporate values and culture. We then provide evidence for three underlying dimensions transcending all four models. They are values that guide relationships (...) and self-regulation; values that describe desired outcomes and performance; and values that inform learning and change. Next, we present the results of a qualitative study describing how these companies put their values into practice. Finally, using publicly available information from the Great Place to Work® Institute, we show how the espoused values we identified relate to: what employees report about their experiences and company self-descriptions. Our findings highlight connections between leadership and values and they offer guidance to those seeking to understand keys to values-based cultures. (shrink)

The basis of the Periodic Table is discussed. Electronic configuration recurs in only 21 out of the 32 groups. A better basis is derived by considering the highest classical valency (v) exhibited by an element and a new measure, the highest valency in carbonyl compounds (v*). This leads to a table based on the number of outer electrons possessed by an atom (N) and the number of electrons required for it to achieve an inert (noble) gas configuration (N*). Periodicity of (...) these is nearly complete. The new basis helps to settle the question of the best form of table and related issues. (shrink)

A new way of understanding entropy as a macroscopic property is presented. This is based on the fact that heat flows from a hot body to a cold one even when the hot one is smaller and has less energy. A quantity that determines the direction of flow is shown to be the increment of heat gained divided by the absolute temperature. The same quantity is shown to determine the direction of other processes taking place in isolated systems provided that (...) q is determined by the state of the system. Entropy emerges as the potent energy of a system [Σ], the potency being determined by 1/T. This is shown to tie in with the statistical mechanical interpretation of entropy. The treatment is shorter than the traditional one based on heat engines. (shrink)

In recent years, observational techniques at cosmological distances have been sufficiently improved that cosmology has become an empirical science, rather than a field for unchecked speculation. There remains the fact that its object, the whole universe, exists only once; hence, we are unable to separate “general” features from particular aspects of “our” universe. This might not be a serious drawback if we were justified in the belief that presently accepted laws of nature remain valid on the cosmological scale. In the (...) author's opinion, however, there are grounds for doubting that belief. The three arguments presented are (1) the possibility that apparent constants of nature may, during cosmological times, turn out to vary (Dirac conjecture); (2) the effective breakdown of the principle of relativity caused by the effects of the cosmological environment on local experiments; and (3) the fact that present theory leads to field singularities at the early stages of the expanding universe, which might be a signal that currently accepted theoretical concepts are inadequate for an understanding of highly condensed matter.

We survey the theory of Mucnik and Medvedev degrees of subsets of $^{\omega}{\omega}$with particular attention to the degrees of $\Pi_{1}^{0}$ subsets of $^{\omega}2$. Sections 1-6 present the major definitions and results in a uniform notation. Sections 7-6 present proofs, some more complete than others, of the major results of the subject together with much of the required background material.

Thirty-two years ago W. V. Quine proposed a definition of 'logical truth' that has been widely repeated and reprinted. Quine himself seems to have recognized that this definition is wrong in detail; in section 1 we eliminate this fault. What has perhaps been less widely observed is that, in abandoning the model-theoretic account of logical truth in favor of a "substitutional" account, Quine's definition swells the ranks of the logical truths and makes the classification of a sentence as a logical (...) truth dependent both on the interpretation of its extralogical words and on the extralogical vocabulary available in the language.

The view that metaphysics is a waste of time appears to be gaining in popularity. It is held openly by many scientists and even many philosophers. I argue here that this is a consequence of the way metaphysics is usually done and the futility of a certain approach to it, and not a reason to suppose there is no useful knowledge to be acquired from its study. -/- .

There is a widespread view that Buddhist philosophy embodies logical contradictions such that there would be 'true' contradictions, This article explains that this is not the case and that Buddhist philosophy, more generally the Perennial philosophy, denies all contradictions for the sake of a doctrine of Unity.

Some time ago, in an article for the Journal of Consciousness Studies, David Chalmers challenged his peers to identify the ingredient missing from our current theories of consciousness, the absence of which prevents us from solving the 'hard' problem and forces us to make do with nonreductive theories. Here I respond to this challenge. I suggest that consciousness is a metaphysical problem and as such can be solved only within a global metaphysical theory. Such a theory would look very like (...) the information theory proposed by Chalmers, but with the addition of an extra phenomenon that would allow it to become fundamental. (shrink)

No descriptive material is available for this title.

The difficulties of philosophy reflects the nature of reality. Here it is proposed that the inability of scholastic philosophers to solve philosophical problems is a clear indication that neither philosophy nor reality is as complicated as they believe, but that its conceptual simplification cannot be achieved when we reject nondualism and endorse extreme and partial world-theories.

As a fan of Sherlock Holmes from a young age it occurred to me recently to wonder what the great detective would have made of the 'hard' problem of consciousness. Here is one possible scenario.

More than thirty-five years ago, a longitudinal study was established to research the health and well-being of older people living in an English city. Self and Meaning in the Lives of Older People provides a unique set of portraits of forty members of this group who were interviewed in depth from their later seventies onwards. Focusing on sense of self-esteem and, especially, of continued meaning in life following the loss of a spouse and onset of frailty, this book sensitively illustrates (...) these persons' efforts to maintain independence, to continue to have a sense of belonging and to contribute to the lives of others. It examines both the psychological and the social resources needed to flourish in later life and draws attention to this generation's ability to benefit from strong family support and from belonging to a faith community. In conclusion, it questions whether future generations will be as resilient. (shrink)

A tongue-in-cheek marketing review of university philosophy prompted by a slow-down in sales and mounting criticism of the product. These problems are diagnosed as the consequence of an inward-looking culture that encourages a narrow and fixed focus on selling the traditional product while discouraging examination of its competitors.
