Reply to "Comment on 'Surface restructuring, kinetic oscillations, and chaos in heterogeneous catalytic reactions' ".

In my numeration, the criticism of my simulations of kinetic oscillations in NO reduction by H2 on Pt(100) [V. P. Zhdanov, Phys. Rev. E 59, 6292 (1999)] by Kuzovkov, Kortlüke, and von Niessen [preceding paper, Phys. Rev. 63, 023101 (2001)] contains 19 comments. I show that four comments are irrelevant. The other 15 comments are wrong, because they either contradict the basic principles of the theory of phase transitions, Monte Carlo simulations, and catalytic chemistry or ignore numerous experimental data on adsorbate-induced restructuring of the Pt(100) surface.

Comment on "Origin of the excess wing and slow beta relaxation of glass formers: a unified picture of local orientational fluctuations".

In a recent paper [Phys. Rev. E 69, 021502 (2004)]], Tanaka commented on an old coupling model interpretation of the Johari-Goldstein (JG) secondary relaxation [J. Chem. Phys. 115, 1405 (2001)]]; namely, that it implies not all molecules contribute to the JG relaxation. In this Comment, I point out to the readers that this old interpretation has been revised in recent publications [J. Phys.: Condens. Matter 15, S1107 (2003)]; J. Phys. Chem. B 107, 6865 (2003)]; J. Chem. Phys. 120, 857 (2004)]; Macromolecules 37, 8123 (2004)]]. In the new interpretation, essentially all molecules contribute to the JG relaxation. Another comment of Tanaka that applies to both the old and the new interpretation is discussed and shown to be of no practical significance.

Reply to the comments on "Local Overfitting Control via Leverages" in "Jacobian Conditioning Analysis for Model Validation" by I. Rivals and L. Personnaz.

"Jacobian Conditioning Analysis for Model Validation" by Rivals and Personnaz in this issue is a comment on Monari and Dreyfus (2002). In this reply, we disprove their claims. We point to flawed reasoning in the theoretical comments and to errors and inconsistencies in the numerical examples. Our replies are substantiated by seven counterexamples, inspired by actual data, which show that the comments on the accuracy of the computation of the leverages are unsupported and that following the approach they advocate leads to discarding valid models or validating overfitted models.

Three-systems theory of human visual motion perception: review and update: comment.

This comment addresses two issues raised by Lu and Sperling [J. Opt. Soc. Am. A 18, 2331 (2001)]. These authors stated that stereomotion (movement of binocular disparity) is processed exclusively by a third-order motion system that involves feature tracking. This comment discusses evidence that clearly shows that stereomotion is processed by a low-level mechanism that does not track features. Lu and Sperling also claimed that motion signals from binocular rivalry have confounded many stereomotion experiments in the past. This comment discusses how stimuli employed in most previous studies of stereomotion processing would not produce rivalry.

Critical comments made to schizophrenic patients by their families in Japan.

Critical comments (CCs) are one of the components of expressed emotion (EE), an excess of which is related to relapse. Therefore, CCs could be a target of family psychoeducation. We examined the nature of CCs for clues to family therapy. We classified CCs expressed in the Camberwell Family Interview (CFI) into nine categories: (1) positive symptoms, (2) negative symptoms, (3) compliance with medical care, (4) life problems, (5) socially inappropriate behavior, (6) aggression, (7) rejection, (8) premorbid personality, and (9) other. Positive symptoms were the most frequently commented on (34%). Negative symptoms were not so frequently commented on (11%), as expected. In comparing high-EE and low-EE relatives or relapsers and nonrelapsers, there were no significant differences in the distribution of the nine CC categories. We conclude that positive symptoms should be a main topic of family psychoeducation in such cases.

The patient comment card: a system to gather customer feedback.

Continuous patient feedback can give important information to hospitals about the quality of care they provide. The Patient Comment Card (PCC), a brief form that can be used to gather open-ended comments from patients and to measure quality, was developed during a two-year period and was extensively evaluated in a series of three pilot tests involving more than 2,000 patients discharged from five hospitals. Evaluation results demonstrate that the questionnaire elicits useful comments from patients and can generate statistically reliable scores and valid quality measures. However, in a field trial in four hospitals, low response rates (15%-27%) reflected, first, lack of follow-up of non-respondents, and second, the fact that most of the PCC quality scores were upwardly biased; these inflated scores were likely to reflect the low response rate. Tools such as the PCC should be used judiciously, given the possible abuses and misinterpretations of hospital quality scores.

Pre-registration house officers' comments on working in the NHS: a qualitative study of the views of UK medical graduates of 1999.

The authors aimed to report the views of pre-registration house officers (PRHOs) on their experience of working in the UK National Health Service (NHS). All doctors who qualified from UK medical schools in 1999 were surveyed towards the end of their pre-registration year. Structured questions concerning career choices and experiences were accompanied by a form inviting free-text comment. Comments were transcribed and coded by topic. Those related to working conditions were selected for analysis. Respondents commented that aspects of the PRHO year had been enjoyable but were critical of working conditions. For instance: heavy workloads caused working hours to regularly contravene contractual limits, out-of-hours pay did not accurately reflect responsibilities, out-of-hours facilities were sometimes poor. A few respondents' experiences had deterred them from continuing their NHS hospital training. Most PRHOs had enjoyed the year despite poor working conditions; for a few, their educational experience was marred.

The effect of comments about shoe construction on impact forces during walking.

UNLABELLED: Comparisons of ground reaction forces (GRF) during gait are not typically conducted with blinding of the varied shoe characteristic, raising concerns related to the existence of a placebo effect, or a subject response based on a perceived expectation of change. PURPOSE: To determine whether investigator comments on shoe construction influenced GRF measures and ratings of shoe cushioning during walking. METHODS: 19 female college students volunteered for a study presented as a test of a new shoe material. The study involved walking (2.5 m x s(-1)) under three shoe conditions (SC). Shoes in SC2 and SC3 were harder than those in SC1, but shoes in SC1 and SC3 looked similar. Subjects in a mislead group (N = 9) were told SC1 and SC3 were baseline measures in a standard shoe, with SC2 misleadingly described as a shoe constructed of unique new material. A control group performed the same three conditions without investigator description. GRF data were collected for 10 trials for each subject in each condition, and subjects rated the perceived cushioning of each shoe. GRF data and perceived cushioning scores were analyzed using mixed-factor (group by shoe) ANOVA. RESULTS: A significant shoe main effect was found for loading rate. Post hoc tests identified the difference between SC1 and both SC2 and SC3. The group main effect was not significant for any dependent variable. CONCLUSIONS: Results suggest that, as a group, GRF data and cushioning scores are not affected by investigator comments that do not match shoe construction characteristics. However, ratings of perceived shoe cushioning by some individual subjects reflected investigator comments and not the vertical GRF variables.

Reply to comments on "Simple measure for complexity"

We respond to the comment by Crutchfield, Feldman, and Shalizi [Comment in this issue, Phys. Rev. E 62, 2996 (2000)] and that by Binder and Perry [preceding Comment, Phys. Rev. E 62, 2998 (2000)], pointing out that there may be many maximum entropies, and therefore "disorders" and "simple complexities." Which ones are appropriate depend on the questions being addressed. "Disorder" is not restricted to be the ratio of a nonequilibrium entropy to the corresponding equilibrium entropy; therefore, "simple complexity" need not vanish for all equilibrium systems, nor must it be nonvanishing for a nonequilibrium system.

Assessing the quality of comments on reports: a retrospective study.

I describe a comparatively simple method for assessing the quality of comments on clinical biochemistry reports. It is based on independent peer review of components of comments, appears reasonably robust and correlates well with separate independent assessment of the value of complete comments. The method gives a numerical score, and thus lends itself to a wide range of statistical manipulations and assessment for education and audit purposes.

Reviewers' comments.

The large number of nonexperimental manuscripts submitted to JABA and the lack of well-defined criteria for evaluating them, has necessitated formulation of a separate editorial policy (see policy statement on page 404 of this issue). The manuscript by Alan E. Kazdin was submitted before the policy concerning nonexperimental manuscripts went into effect and was reviewed by three established researchers who have made substantial methodological contributions to the field (Montrose M. Wolf, Murray Sidman, and L. Keith Miller were Reviewers A, B, and C, respectively). On the basis of the reviewers' comments, it was decided to publish the manuscript with only minor changes. However, because of the fundamental importance of many of the issues discussed in Kazdin's paper and because of the lack of clear agreement on some of these issues, as exemplified in the reviewers' comments, these comments are presented below.

[The effects of information relevance to speaker vs. hearer on the use of comment expressions and interrogative sentences in the Japanese language].

This study examined how the relevance of information to the speaker and the hearer affected the use of comments and interrogative sentences. Subjects read scenarios and rated the necessity of an expression (Experiment 1) or the naturalness of expressions (Experiment 2) in each of the situations. Experiment 1 investigated the use of comments, which preceded the information, to show the speaker's uncertainty about the information contents (subjects: 138 undergraduates). The less the information was relevant to the speaker and/or the more it was relevant to the hearer, the more the comments were judged to be necessary. Experiment 2 investigated the use of interrogative sentences, declarative sentences, and declarative sentences + a sentence final particle 'ne' (subjects: 96 undergraduates). Interrogative sentences were judged to be the most natural in the conditions where the information was relevant to the hearer and not to the speaker, whereas declarative sentences were judged to be the most natural where the information was relevant to the speaker and not to the hearer. Declarative sentences + 'ne' showed intermediate patterns of use between interrogative sentences and declarative sentences.

Organ Procurement and Transplantation Network--HRSA. Final rule with comment period.

This document sets forth the final rule governing the operation of the Organ Procurement and Transplantation Network (OPTN), which performs a variety of functions related to organ transplantation under contract with HHS. The document also offers a 60 day period for additional public comment. The rule will become effective 30 days following the close of the comment period. If the Department believes that additional time is required to review the comments, we will consider delaying the effective date. In combination with a new National Organ and Tissue Donation Initiative, this rule is intended to improve the effectiveness and equity of the Nation's transplantation system and to further the purposes of the National Organ Transplant Act of 1984, as amended. These purposes include: encouraging organ donation; developing an organ allocation system that functions as much as technologically feasible on a nationwide basis; providing the bases for effective Federal oversight of the OPTN (as well as for implementing related provisions in the Social Security Act); and, providing better information about transplantation to patients, families and health care providers.
