Comments on "Dynamical optimal training for interval type-2 fuzzy neural network (T2FNN)".

In this comment, it will be shown that the backpropagation (BP) equations by Wang et al. are not correct. These BP equations were used to tune the parameters of the antecedent type-2 membership functions as well as the consequent part of the interval type-2 fuzzy neural networks (T2FNNs). These incorrect equations would have led to erroneous results, and hence this might affect the comparisons and findings presented by Wang et al. This comment will highlight the correct BP tuning equations for the T2FNN.

Using prior distributions to synthesize historical evidence: comments on the Goodman-Sladky case study of IVIg in Guillain-Barré syndrome.

One feature of the Bayesian approach is that it provides methods for synthesizing what is known about a question of interest and provides a formalism based on the laws of probability for incorporating this auxiliary knowledge into the planning and the analysis of the next study. In this comment, we use elements of the Goodman-Sladky case study to illustrate (1) the use of Bayesian methods to quantify historical information about an intervention through the specification of a prior distribution, (2) an approach to the analysis of the sensitivity of the conclusions of a Bayesian analysis to the specification of the prior distribution, and (3) we comment on the role of research synthesis for combining information about an intervention from different data sources as a tool to help summarize evidence about the intervention.

Patient comments concerning psychiatric hospitalization.

During the past decade increasing attention has been paid to consumer assessment of mental health services. This study summarizes and interprets the comments made by 1457 adults and 474 adolescents concerning their inpatient care at a large private psychiatric hospital. Although adult and adolescent comments evidenced many similarities, adolescents tended to give a greater number of responses and to be more critical of hospitalization than were adults. Comparisons with previous research also supported findings that individual therapy is the most highly valued treatment modality, while food, finances, and living conditions are the most commonly criticized aspects of psychiatric hospitalization.

Patients' comments on psychiatric inpatient treatment experiences: patient-therapist relationships and their implications for treatment outcome.

Only few researchers pay systematic attention to what patients may have to say about their treatment experience during psychiatric hospitalization. This study not only delineates the various therapeutic aspects of an open psychiatric inpatient unit based on the patients' comments, but also attempts to correlate the data with the objective outcome of treatment rated clinically by the therapists and independently by the author. Positive patient-therapist relationship has been found to be the most significant factor correlated closely with the treatment outcome. The correlation may support the relevance of the patients' comments regarding subjectively perceived therapeutic benefits vs. objective actual benefits.

[Responsibility of the anaesthetist in preoperative risk management. Comments on the legal implications of medical publications in this field].

There is an increasing number of publications in the medical literature which address the medical and legal obligations of a specialist in a given field. These articles, mostly editorials, seek to delineate the optimal course of treatment based on the current state of the art and science of medicine. However, we believe that the unreflected adoption of these often highly theoretical ideas and suggestions carries its own dangers. For one thing, there is the threatening financial crisis in the public health system. In addition, the feasibility of implementing these suggestions in routine medical and surgical practice is questionable. Last but not least, suggestions and guidelines for preoperative risk management by, for instance, Lingnau and Strohmenger 2002 cross the well established boundaries of the various medical and surgical specialties, which obviously demands careful deliberations among the specialties involved. So far, few specialty boards have seen fit to act on these suggestions. Our article on the medical and legal responsibilities of the anaesthesiologist in perioperative risk management restates the aforementioned concerns. We attempt to point out medical and legal points of controversy. In particular, we caution against the ever present danger of a bona fide adoption of visionary guidelines as the "standard of care" by both medical and legal experts. We feel that it is imperative to carefully evaluate editorial comments and suggestions, however well meaning, in the light of established teaching and practice, lest these comments and suggestions become the basis of an unjustified determination of a physicians innocence or guilt in a court of law.

Fundamental comments on cell polarography according to Velazquez and Rosado.

Some fundamental comments are made on cell polarography according to Velázquez and Rosado (Fertil Steril 23:562, 1972). The results which they have obtained cannot be reliable because fundamental mistakes are made against the principles of the electroanalytic techniques used. We comment upon the conductometry, the amperometric titrations, and the alternating-current polarography as carried out by Velázquez and Rosado.

Isthmiophora Lühe, 1909 and Euparyphium Dietz, 1909 (Digenea: Echinostomatidae) re-defined, with comments on their nominal species.

The validity of Isthmiophora Lühe, 1909 in relation to Euparyphium Dietz, 1909 is discussed and confirmed. Isthmiophora melis Schrank, 1788) [the type-species] and I. inermis (Fuhrmann, 1904) n. comb. are redescribed, and diagnoses are given for both genera, along with lists of their presently-accepted constituent species which are commented upon where necessary. A similar list of species previously allocated to these genera is also presented with comments on their current status. A key to the species of Isthmiophora is included. New combinations for species previously attributed to Euparyphium are: Isthmiophora inermis (Fuhrmann, 1904) n. comb., I. beaveri (Yamaguti, 1958) n. comb., I. lukjanovi (Chertkova, 1971) n. comb., I. citellicola (Kadenatsii in Skrjabin & Bashkirova, 1956) n. comb., I. hortensis (Asada, 1926) n. comb., Echinostoma pindchi (Khan & Chishti, 1985) n. comb., Echinoparyphium tripathii (Gupta & Gupta, 1982) n. comb., E. hirundonis (Fischthal & Kuntz, 1976) n. comb., and Hypoderaeum longitestis (Verma, 1936) n. comb. Species attributed to Euparyphium which are here considered species inquirendae are: E. lobata Farooq & Yousuf, 1986 sp. inq., E. ochoterenai Cerecero, 1943 sp. inq., E. sobolevi Ryzhikov, 1965 sp. inq., and E. taiwanense Fischthal & Kuntz, 1976 sp. inq.

Experiential learning in an anaesthesia simulation centre: analysis of students' comments.

The anesthesia computer-controlled patient simulator offers a valuable experiential learning experience for undergraduate medical students. The purpose of this study was to gather students' opinions of the simulator learning experiences and to study and analyze their comments regarding the nature of the learning. All fourth-year medical students were invited to participate in a simulator session during their anesthesia rotation. A satisfaction survey was administered and the qualitative data were analyzed. A total of 145 students completed the questionnaire (100% return rate). Most students (88%) reported the session to be a positive learning experience that provided opportunities for applying their knowledge in a realistic environment. Some students indicated a lack of comfort in the environment but this did not appear to inhibit performance. Student comments highlighted the value of the learning experience and provided insights into the nature of the learning. The computer-controlled patient simulator offers new and challenging opportunities for medical students to apply their knowledge and practice working through an Anesthesia case without endangering patient safety.

Reductionism in the comments and autobiographical accounts of prominent psychologists.

Many of the researchers in the field of psychological science use strategies and methods in which human actions and experiences are reduced to behavioral contingencies, statistical regularities, neurophysiological states and processes, and computational functions and models. However, many psychologists talk readily and easily about how their research might assist human agents to solve problems, cope, make decisions, self-regulate, and more generally "make a difference" and "take control." The authors considered informally selected comments by several eminent psychologists, and more formally, 73 autobiographical accounts of prominent psychologists to see what could be learned about the attitudes of these psychologists toward reductionism in their own work and in the field of psychology in general. In interpreting these comments and accounts, the authors posit a gap between many psychologists' contemplation of their work and their actual research practices. The authors also suggest that such a gap may be related to psychologists' educational experiences and their scholarly and professional socialization, as well as to their subdisciplinary attachments and contexts.

Further user comments regarding usage of an interactive educational diabetes simulator (AIDA).

This "Diabetes Information Technology & WebWatch" column continues the diabetes simulation theme from previous issues and overviews various user experience with the AIDA v4 interactive educational freeware diabetes simulator. AIDA is a diabetes computer program that permits the interactive simulation of plasma insulin and blood glucose (BG) profiles for educational, demonstration, and self-learning purposes. It has been made freely available, without charge, via the Web as a noncommercial contribution to continuing diabetes education. Since its Internet launch in 1996, over 145,000 visits have been logged at the AIDA Website--www.2aida.org--and over 29,000 copies of the program have been downloaded, free of charge. While these statistics may appear impressive, they do not tell the personal story of how people have been making use of the software, and what they actually think about the program. In this respect, this column documents some of the independent user comments about AIDA sent in spontaneously via electronic mail (email) by patients with diabetes and their relatives, as well as by health-care professionals. Comments posted to diabetes newsgroups and diabetes email lists, as well as a selection of those which have been found at other, linked, diabetes Websites are also highlighted.

General practitioners' comments on video recorded consultations as an aid to understanding the doctor-patient relationship.

The aim of this study was to describe, understand and interpret physicians' experiences of consultations. Forty-six consultations were videotaped in four primary health care centres. Twelve general practitioners and 46 patients participated. Afterwards the patients and the physicians (on different occasions) commented on the recorded consultations. The comments were analysed from an inductive as well as a hypothetical-deductive model. The analyses agreed well with each other. The result demonstrated that the physicians often had difficulties understanding the patient, that they did not really know how to handle the conversation and felt that they did not really understand the context. The perceived relation to the patient was mainly related to the patients' ability to give adequate information. It is concluded that a key factor in communication is the difficulty which the physician has in understanding what the patient in fact wants-the failure to be on the same wavelength so that the message from the patient can be received.

Reply to "Comment on 'Monte carlo study of structural ordering in charged colloids using a long-range attractive interaction' "

In the Comment by Grier and Crocker (preceding paper) the authors tried to refute our criticism [Phys. Rev. E 58, 2237 (1998)] on their work [J. C. Crocker and D. G. Grier, Phys. Rev. Lett. 77, 1897 (1996)] by simply fitting once again their old experimental data. Grier and Crocker claim that their pair-potential measurements on aqueous dilute suspension of charged colloidal particles confined between charged glass walls at gap of about 8 &mgr;m provide evidence for the failure of Sogami-Ise (SI) theory and demonstrate the applicability of the Dejaguin, Landau, Vervey, and Overbeek (DLVO) theory. Grier and Crocker do not provide additional experimental proof to counter our criticism. We continue to claim here based on our conductivity and conductometric titration measurements, which allow estimating the effective charge and determining the number and nature of the dissociable sites respectively, that their measurements using not well-characterized samples cannot provide clear evidence for the failure of SI theory. With the evidences available in literature, we refute all of the Grier and Crocker comments, including the effect of charged wall confinement on the measured colloidal interactions.

Reply to comments on "Generation of focused, nonspherically decaying pulses of electromagnetic radiation"

The criticism made by Hannay [preceding Comment, Phys. Rev. E 62, 3008 (2000)] is unfounded since the steps, familiar from the subluminal regime, that are taken in his argument are not mathematically permissible when the distribution pattern of the source is moving and has volume elements that approach the observer with the speed of light and zero acceleration along the radiation direction. In the superluminal regime, the retarded time is a multivalued function of the observation time and so the retarded potential for the radiation from a localized source cannot be represented, as Hannay assumes, by an integral over all space whose integrand entails a differentiable retarded distribution of the source density. Contrary to what is claimed by Hewish [Comment in this issue, Phys. Rev. E 62, 3007 (2000)], moreover, there is no discrepancy between conventional antenna theory and the analysis that appears in Phys. Rev. E 58, 6659 (1998). The characteristics of the new type of emission predicted by this analysis, and received from pulsars, differ from those of the radiation that is produced by known leaky waveguides because there are at present no antennas in which the emitting electric current is both volume-distributed and has the time dependence of a traveling wave with an accelerated superluminal motion.

Spontaneous comments from users of the AIDA interactive educational diabetes simulator.

The user experience with the AIDA simulator demonstrates one of the advantages of making such diabetes software readily available for free via the Internet. The comments collectively provide a picture of some of the many and varied ways in which the simulator has been applied by different users. These comments also demonstrate the potential for empowerment that some people feel can result from the use of the software. The experience with this approach is sufficiently encouraging to warrant formal evaluation studies to quantify the clinical utility of such an interactive educational diabetes simulation program. For this reason, a formal survey of 200 AIDA users (patients, relatives, and healthcare professionals) from at least 15 different countries is currently ongoing, and further formal evaluation studies in the clinic setting are planned.

The use of non-human primates in regulatory toxicology: comments submitted by FRAME to the Home Office.

The Home Office have circulated a document that summarises the discussions of a Primate Stakeholders Forum. The Forum took place in January 2004, and was convened to address the issues raised and the recommendations made in the Animal Procedures Committee 2002 report on the use of primates under the Animals (Scientific Procedures) Act 1986. The report emphasises the need for more resources focused on alternatives to toxicological testing in primates, including harmonising worldwide regulatory requirements, investigating the relevance of primate models, and improving the retrospective analysis of procedures involving primates. The document called for reasoned comments about the report to be submitted to the Home Office. In response, FRAME submitted a comprehensive paper, which evaluated each of the Animal Procedures Committees recommendations, along with the Home Office Forums comments. FRAME believes that, in coming to a decision as to whether primates should be used for regulatory testing, there must be full consideration of all the information available, including whether the ethological needs of any given species can be met prior to, during and following experimental use. Where these needs cannot be met, there must be a concerted effort to develop alternative models for research and testing. However, this should not detract from the ultimate goal of phasing out primate research altogether.
