Explanatory character

In the following table the characters of the principal isomerides and other transformation products of the cinchona alkaloids are summarised and references are given to the chief papers dealing with them, and upon which the foregoing account is based. The capital letters in brackets printed after the names of the substances refer to the formulae and explanatory footnote on p. 449. 

That the authorities have refused unreasonably to accept compliance with alternative requirements or that the requirements of the notice are otherwise unreasonable in character or extent, or are unnecessary. This defense is self-explanatory. The local authorities are only permitted to ask for works that will abate the noise nuisance. Other works (perhaps to comply with legislation) should not be specified in the notice. They may, however, be contained in a letter separate from the notice. An example of this would be where the fitting of acoustic enclosures to food-manufacturing machines breached food hygiene requirements. Readily cleanable enclosures may be a requirement of the Food Hygiene Regulations, but it should not be contained in a Section 58 Control of Pollution Act notice. 

Lucidity. The authors have found students who understand advanced courses in quantum mechanics but find difficulty in comprehending a field at whose center lies the quantum mechanics of electron transitions across interfaces. The difficulty is associated, perhaps, with the interdisciplinary character of the material a background knowledge of physical chemistiy is not enough. Material has therefore sometimes been presented in several ways and occasionally the same explanations are repeated in different parts of the book. The language has been made informal and highly explanatory. It retains, sometimes, the lecture style. In this respect, the authors have been influenced by The Feynman Lectures on Physics. 

Below are five illustrative examples of the explanatory power of classical physics in structural chemistry. In these examples, classical electrostatic interactions are used with the electron-domain representation of molecules to explain or to derive The New Walsh Rules , the Langmuir-Pauling and Hendricks-Latimer Occupancy Rule, the s-character Rule, the Methyl Group — Tilt Rule, and the Octet Rule. 

A significant simplification in the electronic interpretation of chemistry can, in fact, be achieved by introducing the Exclusion Principle at the very beginning of the discussion 153>. The justification for this procedure lies chiefly in the simplicity of the results, their visualizable character, and their explanatory power. 

Each set of coordinates deposited with the PDB becomes a separate entry. Each entry is associated with an accession PDB code with a unique set of four alphanumeric characters. PDB and its mirror sites offer a text search engine that uses an index of all the textual information in each PDB record (e.g., PDB ID) an example of such an index is 1LYZ for hen s egg-white lysozyme. The first character is a version number. An identifier beginning with the number 0 signifies that the entry is purely bibliographic. The pdb file is a text file with an explanatory header followed by a set of atomic coordinates. The atomic coordinates are subjected to a set of standard stereochemical checks and are translated into a standard entry format for example, Figure 4.10 shows partial coordinate file for ILYZ.pdb or pdblLYZ.ent. 

There Is iw welfststed altenuNve to the view that ma)or Marxian explanatory claims are fucvctional in character" (iM., p. 279). The hAowin discussion is intended to point to one such alternative. 

A further way to fix the referent of the term phenomenal character is to say that it is what gives rise to the explanatory gap (Levine, 1983). Tell me everything you like about what goes on physically and functionally in someone who is experiencing red, and, it seems, you still won t have told me what it is like to experience red. For even after I have all the relevant physical and functional information, I can still intelligibly ask, Why do those physical and functional goings-on generate that phenomenal character (the phenomenal character of the experience of red) Why couldn t another phenomenal character be present ... 

Up to now, we have reflected upon a family of partly competing and partly complementary theses about the metaphysics of the mind, and on how these theses can be illustrated by reference to the explication of reduction. These theses remain silent about the epistemic or procedural character of reductions (except for the highly implausible idea that the relevant identity-statements express a priori tmths) and about explanatory aspects of reduction. In the philosophy of mind, the dominant view about the link between reduction and explanation is that functional reduction somehow goes together with functional or mechanistic explanation. Functionalism also yields a theory of the metaphysics of mental properties and, contrary to ordinary type-identity theories, it explicitly employs the term reduction .
