The Making of Readers

In considering the process of developing anything, we must have in mind a clear concept of the end product we are hoping to attain. In considering the developing in children of an appreciation of literature, we are aiming at producing life-time readers, children and ultimately adults who will turn with confidence to books (using a general term) for information and pleasure. Now in the day of relatively cheap printing, and hence, an overwhelming amount of inferior material, we must qualify the word books with the word good. And though such a description is woefully open to a carping kind of What do you mean? criticism, I am fairly sure that most readers know what we mean. To add the term of literary value, only weakens the position to me. I can but repeat that what we are trying to do in presenting good books to our young is make readers of as many of them as possible—readers in the same general sense as a ballet mistress aims to make dancers of her pupils, or a track man to make runners of his. The end in all three cases involves a high standard and a discipline that scarcely has to be defined. There may well be several steps to note in the making of readers

An analysis of formal errors in a corpus of l2 English produced by Chinese students

This paper describes the investigation of a small corpus of writing of English for academic purposes produced by L1 speakers of Mandarin. The investigation involved the development of a tagset for the identification of formal errors in the corpus, and the subsequent analysis of these errors with a view to creating remedial grammar materials for Chinese students studying in the medium of English. Some past approaches to error analysis are discussed, the process of developing the tagging system is described, and error types are identified, categorised, quantified, described and (as far as possible) explained

Quantum simulation of spin ordering with nuclear spins in a solid state lattice

An experiment demonstrating the quantum simulation of a spin-lattice Hamiltonian is proposed. Dipolar interactions between nuclear spins in a solid state lattice can be modulated by rapid radio-frequency pulses. In this way, the effective Hamiltonian of the system can be brought to the form of an antiferromagnetic Heisenberg model with long range interactions. Using a semiconducting material with strong optical properties such as InP, cooling of nuclear spins could be achieved by means of optical pumping. An additional cooling stage is provided by adiabatic demagnetization in the rotating frame (ADRF) down to a nuclear spin temperature at which we expect a phase transition from a paramagnetic to antiferromagnetic phase. This phase transition could be observed by probing the magnetic susceptibility of the spin-lattice. Our calculations suggest that employing current optical pumping technology, observation of this phase transition is within experimental reach.Comment: 11 pages, 3 figues; Published versio

Efficiency of free energy calculations of spin lattices by spectral quantum algorithms

Quantum algorithms are well-suited to calculate estimates of the energy spectra for spin lattice systems. These algorithms are based on the efficient calculation of the discrete Fourier components of the density of states. The efficiency of these algorithms in calculating the free energy per spin of general spin lattices to bounded error is examined. We find that the number of Fourier components required to bound the error in the free energy due to the broadening of the density of states scales polynomially with the number of spins in the lattice. However, the precision with which the Fourier components must be calculated is found to be an exponential function of the system size.Comment: 9 pages, 4 figures; corrected typographical and minor mathematical error
