Against the golden rule argument against abortion.
R.M. Hare and Harry J. Gensler have each argued that abortion can be shown to be immoral by appealing to a version of the golden rule. I argue that both versions of the golden rule argument against abortion should be rejected: each rests on a version of the golden rule which is objectionable on independent grounds, each is unable to support its conclusion when the rule is satisfactorily modified, and each is unable to avoid the implication that contraception is as wrong as abortion and for the same reason. In addition, some further problems particular to each position are identified.

Abandoning the Golden Rule: the problem with "putting ourselves in the patient's place".
A large body of evidence documents the difficulties health care professionals have in predicting their patient's beliefs or wishes. These difficulties extend from the predictions of very specific patient wishes (such as for life-sustaining therapies) to more global assessments of patients' lives as a whole (for instance, their quality of life). Although many explanations have been offered for this phenomenon, we discuss one that has not received as much attention: the conscious or unconscious adoption of what we refer to as Golden Rule thinking. This refers to our attempts to understand another person's situation by imagining what we would believe or want under similar circumstances, in other words, "putting ourselves in the patient's place." Although Golden Rule thinking would seem to be a promising strategy, studies show that it actually results in inaccurate predictions of patients' wishes or beliefs. These mispredictions, in turn, have significant clinical and ethical implications. We review possible reasons why Golden Rule thinking may be of limited utility in understanding our patients' situations and suggest alternate strategies to maximize our understanding of our patient's lives.

Non-Markovian modification of the golden rule rate expression.
The reformulation of the standard golden rule approach considered in this paper for treating reactive tunneling reduces the computation of the reaction rate to a derivation of band shapes for energy levels of reactant and product states. This treatment is based on the assumption that the medium environment is actively involved as a partner in the energy exchange with the reactive subsystem but its reorganization effect is negligible. Starting from the quantum relaxation equation for the density matrix, the required band shapes are represented in terms of the spectral density function, exhibiting the continuum spectrum inherent to the interaction between the reactants and the medium in the total reactive system. The simplest Lorentzian spectral bands, obtained under Redfield approximation, proved to be unsatisfactory because they produced a divergent rate expression at low temperature. The problem is resolved by invoking a refined spectral band shape, which behaves as Lorentzian one at the band center but decays exponentially at its tails. The corresponding closed non-Markovian rate expression is derived and investigated taking as an example the photochemical H-transfer reaction between fluorene and acridine proceeding in the fluorene molecular crystal. The kinetics in this reactive system was thoroughly studied experimentally in a wide temperature range [B. Prass et al., Ber. Bunsenges. Phys. Chem. 102, 498 (1998)].

Crossover of quantum Loschmidt echo from golden-rule decay to perturbation-independent decay.
We study the crossover of the quantum Loschmidt echo (or fidelity) from the golden-rule regime to the perturbation-independent exponential decay regime by using the kicked top model. It is shown that the deviation of the perturbation-independent decay of the averaged fidelity from the Lyapunov decay results from quantum fluctuations in individual fidelity, which are caused by the coherence in the initial coherent states. With an averaging procedure suppressing the quantum fluctuations effectively, the perturbation-independent decay is found to be close to the Lyapunov decay. We also show that the Fourier transform of the fidelity is determined directly by the initial state and the eigenstates of the Floquet operators of the two classically chaotic systems concerned. The absolute value part and the phase part of the Fourier transform of the fidelity are found to be divided into several correlated parts, which is a manifestation of the coherence of the initial coherent state. In the whole crossover region, some important properties of the fidelity, such as the exponent of its exponential decay and the short initial time within which the fidelity almost does not change, are found to be closely related to the properties of the central part of its Fourier transform.

Managing skin cancer--23 golden rules.
From their collective experience in Australia and the USA, dermasurgeons Anthony Dixon and Scott Hall have compiled a list of "golden rules" for general practitioners to help reduce errors and problems with skin cancer management. It is anticipated that these tips will provide a brief yet informative reference when faced with skin cancer management concerns in general practice.

Stability of quantum motion: beyond Fermi-golden-rule and Lyapunov decay.
We study, analytically and numerically, the stability of quantum motion for a classically chaotic system. We show the existence of different regimes of fidelity decay. In particular, when the underlying classical dynamics is weakly chaotic, deviations from Fermi-golden-rule and Lyapounov regimes are observed and discussed.

The six golden rules to improve compliance in hand hygiene.
Improvement of compliance in hand hygiene is probably the most effective step in reducing the incidence of nosocomial infections (NI). But improvement of compliance is known to be complex. Six possibilities for improving compliance are available although some of them may be difficult to carry out. Rule 1: Select an alcohol-based hand rub which has a good skin tolerance and is acceptable to health care workers to use. This has been shown to improve compliance. Rule 2: The hand rub shall be easily available. Wall dispensers near the patient and pocket bottles may well help. Other possibilities should be assessed locally. Rule 3: Implement teaching and promotion of hand hygiene, which has been shown to be very effective. This is may be the most effective tool but will cost time and money. If money is a problem, rule 4 may be the solution. Rule 4: Create a hospital budget which covers all costs involved with preventable nosocomial infection. Combine it with the budget for hand hygiene products. Even a small number of prevented NI largely outweighs the cost of effective hand hygiene products. Rule 5: Get senior staff to set a good example in order to motivate junior staff, because negligence in hand hygiene appears to correlate with the number of professional years. Rule 6: Have the patient-staff ratio well balanced. It has been shown that staff shortage decreases hand hygiene compliance. Other factors may be important as well, but implementation of these 6 golden rules could be an effective step into the right direction.

The Golden Rule and the potentiality principle: future persons and contingent interests.
Duties to future persons are central to numerous key ethical issues including contraception, abortion, genetic selection, treatment of the environment, and population control. Nevertheless, we still seem to be lacking Parfit's 'Theory X', a general theory of beneficence whose appropriateness extends to future generations. Starting from the Golden Rule (TGR), R.M. Hare purportedly derived counterintuitive duties to potential people and 'the potentiality principle'. However, I argue that Hare's derivation involves a hidden and unjustifiable extension from TGR, and show how the most plausible form of TGR is compatible with multiple contradictory principles for the treatment of future persons. I appeal to our own preferences to argue that one extension of TGR follows the spirit of TGR, while the other is deeply implausible. Using the plausible extension, I derive a Contingent Interests Principle (CIP) that offers much promise as Parfit's elusive Theory X. In contrast to Hare's interpretation of TGR, this application provides solid justification for rejecting the potentiality principle.

Golden rule decay versus Lyapunov decay of the quantum Loschmidt echo.
The overlap of two wave packets evolving in time with slightly different Hamiltonians decays exponentially approximate to e(-gammat), for perturbation strengths U greater than the level spacing Delta. We present numerical evidence for a dynamical system that the decay rate gamma is given by the smallest of the Lyapunov exponent lambda of the classical chaotic dynamics and the level broadening U(2)/Delta that follows from the golden rule of quantum mechanics. This implies the range of validity U > the square root of [lambdaDelta] for the perturbation-strength independent decay rate discovered by Jalabert and Pastawski [Phys. Rev. Lett. 86, 2490 (2001)].

'Ten golden rules' for designing software in medical education: results from a formative evaluation of DIALOG.
Evaluation of educational material has become very important in a climate where there is increasing concern with assessing and maintaining quality. DIALOG (acronym for Distance Interactive Learning in Obstetrics and Gynaecology) is an electronic program on CD-ROM for continuing education. A formative evaluation of DIALOG was carried out to determine whether DIALOG was achieving its educational objectives. The results of the evaluation helped to suggest '10 golden rules' for designing software for the purpose of CPD for medical practitioners. These 'rules' should help in designing future software in medical education. They highlight the importance of content, presentation, design, use of hypermedia and multimedia and reduced cost in order to facilitate appropriate use of such programmes.

Experimental verification of fidelity decay: from perturbative to fermi golden rule regime.
The scattering matrix was measured for a flat microwave cavity with classically chaotic dynamics. The system can be perturbed by small changes of the geometry. We define the "scattering fidelity" in terms of parametric correlation functions of scattering matrix elements. In chaotic systems and for weak coupling, the scattering fidelity approaches the fidelity of the closed system. Without free parameters, the experimental results agree with random matrix theory in a wide range of perturbation strengths, reaching from the perturbative to the Fermi golden rule regime.

Magic bullets and golden rules: data sampling in molecular phylogenetics.
Data collection for molecular phylogenetic studies is based on samples of both genes and taxa. In an ideal world, with no limitations to resources, as many genes could be sampled as deemed necessary to address phylogenetic problems. Given limited resources in the real world, inadequate (in terms of choice of genes or number of genes) sequences or restricted taxon sampling can adversely affect the reliability or information gained in phylogenetics. Recent empirical and simulation-based studies of data sampling in molecular phylogenetics have reached differing conclusions on how to deal with these problems. Some advocated sampling more genes, others more taxa. There is certainly no 'magic bullet' that will fit all phylogenetic problems, and no specific 'golden rules' have been deduced, other than that single genes may not always contain sufficient phylogenetic information. However, several general conclusions and suggestions can be made. One suggestion is that the determination of a multiple, but moderate number (e.g., 6-10) of gene sequences might take precedence over sequencing a larger set of genes and thereby permit the sampling of more taxa for a phylogenetic study.

The preparation of background electrolytes in capillary zone electrophoresis: golden rules and pitfalls.
In this article the methodology of the design of suitable background electrolytes (BGEs) in capillary zone electrophoresis (CZE) is described. The principal aspects of the role of a BGE in CZE are discussed with respect to an appropiate migration behavior of analytes, including the transport of the electric current, the buffering of pH, the Joule heat, the electro-endosmotic flow (EOF) and the principal migration and detection modes. The impact of the composition of the BGE upon migration and detection is discussed. It is shown that the total concentration of the BGE is a principal factor and the adjustment of migrating analyte zones according to the Kohlrausch regulating function (KRF) is the principal effect in most of the sample stacking techniques. The number of co-ions and their properties are of key importance for peak shapes of the analyte peaks and for the existence of system zones. The detection of UV-transparent analytes may advanteously be done in the indirect UV mode, by using UV-absorbing co-ions, however, both peaks and dips may be expected in the UV trace in case of multiple co-ionic BGEs. Properties of BGEs can be predicted applying mathematical models and it is shown that with SystCharts, predictions can be given concerning the existence of system zones, detection modes and the peak shapes of analytes for a given BGE. Practical examples of methodological considerations are given in the design of suitable BGEs for four principal combinations of migration and detection modes. The properties of the BGEs selected are exemplified with experimental results. Golden rules are summarized for the preparation of suitable BGEs in CZE.

Golden rules and pitfalls in selecting optimum conditions for high-speed counter-current chromatography.
This paper aims to be an aid to those chemists who are interested in utilizing high-speed counter-current chromatography (HSCCC), which is free of irreversible adsorption and offers high resolution comparable to column chromatography. It explains the selection of HSCCC conditions step by step including the selection of two-phase solvent systems, determination of partition coefficient (K) of analytes, preparation of two-phase solvent system and sample solution, selection of elution mode, flow rate, rotation speed, and on-line monitoring of the eluate. The paper covers both standard HSCCC and pH-zone-refining CCC techniques. Technical terms (italic) unfamiliar to the beginner are comprehensively explained in Glossary. Various examples of two-phase solvent systems used in HSCCC are listed in Appendices A and B. The commercial sources of HSCCC and other CCC instruments are described in detail in the study edited by Berthod [A. Berthod (Ed.), Counter-current Chromatography, Elsevier, Amsterdam, 2003].
