Sample records for expert testimony

  1. Rape trauma syndrome as scientific expert testimony. (United States)

    Block, A P


    Behavioral science studies conducted on rape victims reveal a posttraumatic stress disorder which follows the attack known as rape trauma syndrome. Evidence of rape trauma syndrome can be very useful in explaining the behavior of rape victims. Rape trauma syndrome can help corroborate the victim's assertion of lack of consent and also help the jury understand the typical reactions of rape victims. Courts have held that expert testimony of rape trauma syndrome is admissible as evidence of (i) lack of consent, (ii) the amount of damages in civil suits, (iii) a defense to culpable behavior, and (iv) an explanation for behavior of the victim that is inconsistent with the claim of rape. Rape trauma syndrome meets the requirements for admissibility when it is used for the proper purpose and with adequate safeguards to prevent any unfair prejudice. Based on case precedent on the admissibility of rape trauma syndrome as scientific expert testimony, rape trauma syndrome should be admissible if (i) the evidence presented only shows the typical reactions to rape and does not make any legal conclusions as to whether the victim was raped, (ii) the expert is qualified, (iii) a proper foundation is laid, (iv) liberal cross-examination of the expert is allowed, and (v) the defense can introduce its own expert testimony on rape trauma syndrome.

  2. Expert witness testimony in ophthalmology malpractice litigation. (United States)

    Huang, Grace; Fang, Christina H; Friedman, Remy; Bhagat, Neelakshi; Eloy, Jean Anderson; Langer, Paul D


    To examine the relative qualifications of expert witnesses testifying on behalf of plaintiffs vs defendants in ophthalmology malpractice litigation. Correlational and descriptive study; analysis of expert witness and physician demographic data available on several databases. The Westlaw legal database was searched for ophthalmologist expert witness testimony from January 2006 to June 2014. Physician demographic data were used as the main outcome measures, including length of experience, scholarly impact (as measured by the h-index), practice setting, and fellowship training status and were obtained from state medical licensing board sites and online medical facility and practice sites. H-indices were obtained from the Scopus database. Defendant and plaintiff expert witnesses had comparable mean years of experience (32.9 and 35.7, respectively) (P = .12) and scholarly impact (h-index = 8.6 and 8.3, respectively) (P = .42). Cases tended to resolve on the side of the expert witness with the higher h-index (P = .04). Significantly higher proportions of defendant witnesses were in academic practice (P < .05) and underwent fellowship training (P < .001). Ophthalmologist expert witnesses testifying for both plaintiffs and defendants had over 30 years of experience and high scholarly impact. Practitioners testifying on behalf of plaintiffs were statistically less likely to work in an academic setting and have subspecialty training. Scholarly impact of expert witnesses appeared to affect trial outcomes. Surgical societies should stringently police for appropriate expert witness testimony given by both plaintiff and defense experts in malpractice litigation. Copyright © 2015 Elsevier Inc.

  3. Expert witness testimony in urology malpractice litigation. (United States)

    Sunaryo, Peter L; Svider, Peter F; Jackson-Rosario, Imani; Eloy, Jean Anderson


    To evaluate the credentials of urologists choosing to testify as expert witnesses. As health care reform has become an increasingly important topic in national debate, medical malpractice and related issues have come to the forefront of topics for discussion by the medical community. Physicians are often recruited to testify as expert witnesses in malpractice cases. Defining what constitutes an expert in this setting has been an area of controversy. The Westlaw legal database was searched for medical malpractice litigation. Data regarding number of years of experience and practice setting were obtained for urologists using private practice and hospital listings, academic faculty profiles, and state medical licensing databases. Scholarly impact, as measured by the h-index, was calculated by the Scopus database. Plaintiff expert witnesses were found to have slightly more years of experience vs defendant expert witnesses (35.7 vs 32.2 years, P = .01), but had a lower h-index (6.8 vs 10.2, P = .03), were less likely to practice in the academic setting (39% vs 60%, P = .001), and were more likely to testify multiple times. Urologists testifying for plaintiffs and defendants both had over 30 years of experience on average, with those in the latter having slightly less experience. Defendant witnesses, however, had greater scholarly impact and were more likely to practice in an academic setting. Organizations such as the American Urological Association may wish to re-evaluate guidelines on expert witness testimony, particularly regarding those who testify frequently.

  4. Psychological expert witness testimony and judicial decision making trends. (United States)

    Shapiro, David L; Mixon, LeKisha; Jackson, Melissa; Shook, Jonathan


    Despite the establishment of the Daubert standard in 1993, the evidentiary criteria are rarely used as a basis for admissibility of expert witness testimony in the behavioral sciences. Ever since the promulgation of Frye and the Federal Rules of Evidence, controversy has surrounded the admissibility of expert testimony in courtrooms. There appears to be no existing uniform application of standards governing the admissibility of psychological expert witness testimony. Therefore, it is essential for the psycho-legal communities to explore judicial decision-making trends regarding psychological expert witness evidence. In this current research, psychological expert witness testimony and judicial decision-making will be explored. In preliminary examination, 97 criminal and civil case summaries from the LexisNexis Academic Database involved issues of admissibility. Analyses conducted by eight trained and paired coders revealed that reliability and assistance to the trier of fact were the most often cited reasons for admissibility in courts. Consistent with prior studies, it was also found that the most applied standards for admissibility of psychological evidence were the Federal Rules of Evidence. Interestingly, while the Daubert scientific criteria for admission of scientific testimony were mentioned, they were rarely utilized. A secondary analysis of 167 civil and criminal appellate cases indicated that the reliability of testimony (18% of all cases), ability to assist the trier of fact (17%), the expert witness' qualifications (17%), and the relevance of the testimony (16%) were the most commonly cited reasons for determining admissibility. A tertiary qualitative analysis focusing on these four categories then revealed eight major trends in admissibility of psychological expert evidence. Copyright © 2015 Elsevier Ltd.

  5. Battered women who kill: the impact of expert testimony and empathy induction in the courtroom. (United States)

    Plumm, Karyn M; Terrance, Cheryl A


    Mock jurors (N = 312) viewed a simulated trial involving a woman, charged with the murder of her abusive husband, entering a plea of not guilty by reason of self-defense. Expert testimony was varied using battered woman syndrome, social agency framework, or no expert testimony. Within expert testimony conditions, jurors were presented with opening and closing statements either including or not including instructions aimed at inducing empathy. Results indicate differences in gender and expert testimony for ratings of guilt as well as differences in gender, expert testimony, and empathy induction for perceptions of the defendant.

  6. Expert testimony regarding child witnesses: does it sensitize jurors to forensic interview quality? (United States)

    Buck, Julie A; London, Kamala; Wright, Daniel B


    Does expert testimony on forensic interviews with children help adults distinguish between poorly conducted and well-conducted interviews? This study evaluates the effects of social framework expert testimony regarding child witnesses in a case involving allegations of child sexual abuse. A 2 (Expert Testimony: present or absent) × 3 (Child Forensic Interview Quality: poor, typical, or good) × 2 (Child's Age: 4- or 10-year-old) factorial design was used to examine whether expert testimony is prejudicial or beneficial to jurors (N = 463). The results revealed that, without expert testimony, mock jurors did not consider the forensic interview quality when reaching a verdict. However, with expert testimony, mock jurors were more likely to render guilty verdicts if the interview quality was good versus poor. Further expert testimony increased mock jurors' knowledge about child witnesses. These findings suggest that expert testimony related to the impact of interview techniques on the reliability of children's reports may assist fact-finders in evaluating child abuse cases.

  7. The effects of rational and experiential information processing of expert testimony in death penalty cases. (United States)

    Krauss, Daniel A; Lieberman, Joel D; Olson, Jodi


    Past research examining the effects of actuarial and clinical expert testimony on defendants' dangerousness in Texas death penalty sentencing has found that jurors are more influenced by less scientific pure clinical expert testimony and less influenced by more scientific actuarial expert testimony (Krauss & Lee, 2003; Krauss & Sales, 2001). By applying cognitive-experiential self-theory (CEST) to juror decision-making, the present study was undertaken in an attempt to offer a theoretical rationale for these findings. Based on past CEST research, 163 mock jurors were either directed into a rational mode or experiential mode of processing. Consistent with CEST and inconsistent with previous research using the same stimulus materials, results demonstrate that jurors in a rational mode of processing more heavily weighted actuarial expert testimony in their dangerousness assessments, while those jurors in the experiential condition were more influenced by clinical expert testimony. The policy implications of these findings are discussed. Copyright 2004 John Wiley & Sons, Ltd.

    Manuela Ribeiro


    Full Text Available Objective: To examine whether company compliance with RS-17 influences the characterization of the casual nexus in physical therapists' expert reports of cumulative trauma disorders in the labor court of Pernambuco, Brazil. Method: The sample was composed of seven physical therapists who provided expert testimony regarding cumulative trauma disorder cases in the labor court of Pernambuco, Brazil. Data collection was performed across two stages. In the first stage, the experts answered a sociodemographic survey and requested the identification numbers of recent cases where expert testimony was provided to characterize the causal nexus. In the second stage, the researchers went to the labor court to collect expert testimony data. These experts indicated that of 75 total cases, 31% (N=23 of the companies fulfilled RS-17, whereas 69% (N=52 did not comply with the law. Results: Among the organizations that complied with legislation, 30% of the analyzed expert testimonies showed a positive causal nexus. However, of the companies that did not comply with RS-17, 71% of the expert testimonies revealed a causal nexus. These results indicate that the breach of the law increases the probability that a causal nexus will be determined by 54.8%. Conclusion: The results showed that failure to comply with RS-17 significantly increases the probability that a causal nexus will be determined in physical therapists' expert testimony of cumulative trauma disorders.

  9. Industrial/organizational psychology and the federal judiciary: expert witness testimony and the Daubert standards. (United States)

    Wingate, Peter H; Thornton, George C


    This research examined judicial perceptions of the field of industrial/organizational (I/O) psychology, explored how judges evaluate and weigh I/O psychology expert witness testimony, and scrutinized the use of the Daubert factors in judicial assessments (of social scientific evidentiary reliability. In a mail survey, federal judges were randomly presented with one of four prototypical descriptions of I/O psychology expert witness testimony in civil age discrimination in employment litigation. Judges were found to be relatively unfamiliar with the field of I/O psychology, and few had previously heard or read the testimony of an I/O psychologist. Sixty-six percent of the federal judges rated themselves at least moderately likely to admit the expert's testimony at trial, regardless of the testimony scenario presented. Judges rated the evidence overall as relevant, moderately reliable, moderately probative, and prejudicial. Both judicial familiarity with the field of I/O psychology and prior experience with I/O testimony were found to be positively related to likelihood of admitting the evidence. Manipulations of the scientific foundation for the expert testimony did not substantially affect admission decision. Judges ascribed the most importance to the general acceptance Daubert factor in their evaluation of evidentiary reliability. Implications for the science and practice of I/O psychology in the legal system are presented and discussed.

  10. The impact of Daubert on the admissibility of forensic anthropology expert testimony. (United States)

    Lesciotto, Kate M


    Forensic anthropologists anticipated a significant impact from the 1993 Supreme Court Daubert decision, which addressed the standard of admissibility for expert testimony. In response, many forensic articles cited Daubert in the search for objective techniques or a critique of established subjective methods. This study examines challenges to forensic anthropological expert testimony to evaluate whether Daubert has actually affected the admissibility of such testimony. Thirty cases were identified that addressed the admissibility of the testimony, including 14 cases prior to Daubert and 16 after Daubert. Examination of these cases indicates that post-Daubert cases do not result in more exclusions. Yet, this lack of exclusions may instead be viewed as a manifestation of the field's overall surge toward more objective and quantifiable techniques in a self-regulating response to Daubert. © 2015 American Academy of Forensic Sciences.

  11. Expert testimony pertaining to battered woman syndrome: its impact on jurors' decisions. (United States)

    Schuller, Regina A; Rzepa, Sara


    Participants (N = 200) were presented with a criminal homicide trial involving a battered woman who had killed her abuser. Within the trial, both the response history (passive, active) and presence of expert testimony pertaining to battered woman syndrome (present, absent) were systematically varied. As well, half of the participants in each of these conditions were provided with a nullification instruction informing them that they were free to disregard the law and acquit should a strict application of the law result in an unjust verdict. Results indicated that, compared to the passive response condition, the mock jurors were no less receptive to the expert testimony in the active response condition. The impact of the testimony on participants' verdicts, however, was moderated by the nullification instruction. That is, although the presence of the testimony did result in greater verdict leniency, this only occurred when the mock jurors had been released from a strict application of the law. The implications of these findings are discussed.

  13. The problem of evasive testimony: the expert "waffle". (United States)

    Gutheil, Thomas G


    Confronted with a difficult, unexpected, or confrontational question, an expert witness may answer by attempting to overwhelm the questioner with words, sometimes highly evasive ones, that avoid, rather than actually address, the question asked. Such a discursive response is sometimes called a "waffle," as in "The expert's answer was a waffle." This review notes some examples of this phenomenon and attempts to categorize them in a meaningful way. An ancillary goal of this discussion may be to aid experts in focusing their answers.

  15. Educating Jurors about Forensic Evidence: Using an Expert Witness and Judicial Instructions to Mitigate the Impact of Invalid Forensic Science Testimony. (United States)

    Eastwood, Joseph; Caldwell, Jiana


    Invalid expert witness testimony that overstated the precision and accuracy of forensic science procedures has been highlighted as a common factor in many wrongful conviction cases. This study assessed the ability of an opposing expert witness and judicial instructions to mitigate the impact of invalid forensic science testimony. Participants (N = 155) acted as mock jurors in a sexual assault trial that contained both invalid forensic testimony regarding hair comparison evidence, and countering testimony from either a defense expert witness or judicial instructions. Results showed that the defense expert witness was successful in educating jurors regarding limitations in the initial expert's conclusions, leading to a greater number of not-guilty verdicts. The judicial instructions were shown to have no impact on verdict decisions. These findings suggest that providing opposing expert witnesses may be an effective safeguard against invalid forensic testimony in criminal trials. © 2015 American Academy of Forensic Sciences.

  16. [Legal aspects of medical expert testimony and non-economic damage in civil liability of physician]. (United States)

    Pauković, Hrvoje


    In the establishment of civil liability of physicians for damage caused, it is extremely important to establish all relevant facts for the court to render the appropriate verdict. One of the crucial instruments in the establishment of a presumed civil liability of physicians as well as in the establishment of the criteria for the assessment of a proper award, is the medical expert testimony--utilised as an essential proof. The comprehension of medical and legal professionals' replies to questions which every profession must answer in order to provide an objective access to the claim and a right and full establishment of the factual situation, is the imperative for a correct application of the law in the handling and settling of these claims, especially in the light of the new set up of the concept of non-economic damage. The medical and legal profession shall help placing the problems of civil liability of physicians into real frameworks, preventing any attempts of unnecessary stigmatization of medical profession and cases of unjustified and unfounded indemnification, and it shall objectively and professionally, based on the law, enable a full and absolute protection of patients and third parties and their rights to physical and mental health.

  17. [Malpractice Claims Against Pediatricians - Analysis of Expert Testimonies from the Medical Service of Health Insurance Companies Between 2000 and 2014]. (United States)

    Steinhauer, Heiko; Holzschuh, Joachim; Böhler, Thomas


    Background In Germany, few data are available on medical malpractice claims against pediatricians. On behalf of Statutory Health Insurance Companies their Medical Service (MDK) regularly offers expert testimony in case of allegations during pediatric treatment. Methods Analysis of 374 written pediatric testimonies, documented between September 1st, 2000 and August 31st, 2014. Results 193 allegations against pediatricians were analysed separately for each sector of care (35% concerning outpatients, 28% normal inpatients, and 37% patients treated in an intensive care unit, ICU). Outpatient care led more frequently to malpractice claims regarding diagnosis, most often in the case of dysplasia of the hip (n=6), meningitis (n=5), and pneumonia (n=4). In inpatients, allegations regarding treatment errors were more common and frequently associated with extravasation injury (n=7), as well as periventricular leukomalacia (n=7), sepsis (=6), and intraventricular haemorrhage (n=4) in newborn infants on ICUs. Expert testimony confirmed allegations in 43% of the outpatients, 22% of the normal inpatients and 38% of the ICU patients. Discussion and conclusion The frequency of pediatric malpractice claims seems to depend primarily on the pattern of utilization of pediatric care services. Diagnosis-related constellations leading to malpractice claims in Germany are well-known internationally. Case analysis according to medical care sectors allows comprehensible conclusions for risk management. © Georg Thieme Verlag KG Stuttgart · New York.

  18. Effects of false-evidence ploys and expert testimony on jurors' verdicts, recommended sentences, and perceptions of confession evidence. (United States)

    Woody, William Douglas; Forrest, Krista D


    During interrogations, police may use false-evidence ploys or fabricated claims to convince suspects to confess. Mock jurors read trial materials containing interrogation transcripts with or without a false-evidence ploy and one of two expert witness conditions (present or absent). We examined jurors' verdicts, recommended sentences, and perceptions of the interrogation. Although factual evidence and the defendant's confession remained constant across conditions, false-evidence ploys led to fewer convictions and shorter sentences. Jurors also perceived interrogations with ploys as more deceptive and coercive. Expert testimony reduced convictions and increased interrogation deception and coercion ratings. Across ploy types, participants rated demeanor ploys as less deceptive and recommended longer sentences for confessors. Outcomes reveal important, previously unrecognized consequences of false-evidence ploys. (c) 2009 John Wiley & Sons, Ltd.

  6. Psychological aspects of old men testimony

    Directory of Open Access Journals (Sweden)

    Brkić Snežana


    Full Text Available Aging does not exclude some person s potential witness, but it is factor which can exert influence on tactics of examination of witness. it also influences the evaluation of testimony. Therefore, it is important to know the specific psychological functions of old men, which are in relation with testimony. The most important psychological functions are perception and memory. There are some negative subjective factors by aging as: weakening of sensul sensitivity, weakening of memory, reducing of intelligence, decelerating of psychomotor functions and negative influence of emotional and motivating process on perception. However, we must know that there are some individual differences between old people. Therefore, we should not deny the aged as a witness. The judge must always check the sensual sensitivity of witness, by putting the questions, by court's experiment or by psychological expert opinion. We must also take into consideration the specific features of the aged, when we interrogate them as a witness. In this sense, we can give some recommendations in regard to place, time and manner of their interrogation. That treatment has to enable the accurate and complete statement, from one side, and it also has to disable the harmful effect of criminal procedure to witness, psyche, from the other side.

  7. Epistemic merit, autonomy, and testimony

    Directory of Open Access Journals (Sweden)



    Full Text Available In this paper, it is argued that both the informer and the hearer in a testimonial situation deserve epistemic merit insofar as they contribute to the collaborative achievement of sharing knowledge. The paper introduces a distinction between the ideals of self-sufficiency and epistemic autonomy. The autonomous exercise of our epistemic agency is very often carried out under strong conditions of epistemic dependence. Testimony exhibits a kind of social dependence that does not threaten the autonomy of the subjects that need to consider their own epistemic capacities. When involved in a testimonial situation, both speaker and hearer declare, at least implicitly, the standings they occupy in an epistemic space and are obliged to recognise certain epistemic requirements.

  8. Aesthetic Experience, Mimesis and Testimony

    Directory of Open Access Journals (Sweden)

    Roger W. H. Savage


    Full Text Available In this article, I relate the demand that Paul Ricoeur suggests mimesis places on the way we think about truth to the idea that the work of art is a model for thinking about testimony. By attributing a work’s epoché of reality to the work of imagination, I resolve the impasse that arises from attributing music, literature, and art’s distance from the real to their social emancipation. Examining the conjunction, in aesthetic experience, of the communicability and the exemplarity of a work reveals how Ricoeur’s definition of mimesis as refiguration relates to the “rule” that the work summons. This “rule” constitutes the solution to a problem or question for which the work is the answer. In conclusion, as a model for thinking about testimony, the claims that works make have a counterpart in the injunctions that issue from exemplary moral and political acts. 

  9. The Weight of a Woman's Testimony

    Directory of Open Access Journals (Sweden)

    Abbas Mohammad Elsiddik


    Full Text Available This research attempts to provide a fresh evaluation of a testimony in general and an evaluation of the weight of woman's testimony in particular. By using an empirical methodology, the research responds to the equality issue between women and men as competent witnesses, as Western jurisprudence claims, and the issue of non-equality between women and men as competent witnesses, as Islamic Sharia scholars claim. This study found numerous results, one of which was that womanhood affects a woman's ability to bear in mind a witnessed fact. Therefore, womanhood should be dealt with as a discrediting her testimony factor. Another result was that woman's testimony is admissible, even if she was alone; because womanhood is a factor relating to the weight of a testimony not a stipulation for the admissibility of testimony. Moreover, the research classified testimony in regard to its weight into two kinds. The first kind is Attestation, which always requires corroboration from a man or woman to renders it admissible as evidence. The second kind is Testimony, which does not generally require corroboration, even if the witness is a woman. However, corroboration may be necessary if the testimony has been affected by any discrediting factor regardless the sex of the witness. One more result of the research was that corroboration for testimony is affected by womanhood in certain cases, can be attained by summoning another woman as a witness, inferring factual presumptions, or examining the surrounding circumstances.

  10. Judicial judgement-making and legal criteria of testimonial credibility

    Directory of Open Access Journals (Sweden)

    Dolores Seijo


    Full Text Available Judicial judgement-making in legal and forensic settings is characterised by the information loss model. In comparison to formal reasoning styles, in which information is processed in detail, judicial reasoning styles are mainly informal. Moreover, the experimental literature regarding judges and juries has revealed that reliability is the corner stone of legal judgement-making in legal contexts. This study aims to assess the underlying legal criteria assigned to the credibility of testimonies by judges by evaluating the court archives of judicial judgements in which the verdict rested entirely on the credibility of testimonies. Moreover, given the prevalence of informal reasoning in this context, an analysis was undertaken to determine the use of heuristics which are indicative of informal reasoning. In addition, an analysis of the interaction of both variables and their effect on joint decision-making by legal experts and lay people was assessed. Finally, bearing in mind the limitations of this study, the results are discussed in terms of their implications in the evaluation of testimonial credibility in judicial proceedings.

  14. Trusting others. The epistemological authority of testimony

    Directory of Open Access Journals (Sweden)

    Fernando BRONCANO


    Full Text Available I propose to consider the interpersonal character of testimony as a kind of social bond created by the mutual intention of sharing knowledge. The paper explores the social mechanism that supports this mutual intention starting from an initial situation of modelling the other’s epistemic perspective. Accepting testimony as a joint action creates epistemic duties and responsibilities and the eventual success can be considered as a genuine achievement at the social level of epistemology. Trust is presented here as the symptom that both parties are involved in such a social bond.

  17. Expert System

    DEFF Research Database (Denmark)

    Hildebrandt, Thomas Troels; Cattani, Gian Luca


    An expert system is a computer system for inferring knowledge from a knowledge base, typically by using a set of inference rules. When the concept of expert systems was introduced at Stanford University in the early 1970s, the knowledge base was an unstructured set of facts. Today the knowledge...... base of expert systems is often given in terms of an ontology, extracted and built from various data sources by employing natural language-processing and statistics. To emphasize such capabilities, the term “expert” is now often replaced by “cognitive,” “knowledge,” “knowledge-based,” or “intelligent......” system. With very few exceptions, general-purpose expert systems have failed to emerge so far. However, expert systems are applied in specialized domains, particularly in healthcare. The increasing availability of large quantities of data to organizations today provides a valuable opportunity...

My claim is that this view is mistaken, and yet has something important to say in recognising the essential difference between testimony and other forms of evidence.

  4. The influence of stress on giving testimony

    Directory of Open Access Journals (Sweden)

    Brkić Snežana S.


    Full Text Available In this paper there are firstly some general observations about stress (the concept of stress, stressors, stress responses, consequences of stress. Then, the author examines the effect of stress on giving testimony, that is on two most important psychic functions of the importance for giving testimony: perception and memory. The impact of stress, on perception is discussed in the framework of the importance of affective tone of perception. The lower doses of stress can improve attention and perception, but with intense stress, attention rapidly decreases. Stress often causes erroneous perception of time and other errors in observation and can lead to illusions and hallucinations. The errors in face recognition are also possible in view of 'the phenomenon of focusing attention on weapon '. In relationship with memory, the author firstly gives some general considerations about this function. Then follows brief overview of memory for emotionally colored events. The negative influence of stress on memory is reflected in the possibility of psychogenic amnesia, which are often the escort of psychological trauma. Further, some events will be remembered with a lot of gaps, distortions and overemphasis. The paper points to a number of studies on (inaccuracies and (incomplete memories for traumatic events. Summarizing the main results of these studies it is concluded that memory for traumatic events has similar sharacteristics as memory for normal, nontraumatic events. Memory for traumatic events also follows the same cognitive principles. In that sense, both traumatic and nontraumatic memories can be equally powerful on the one hand, and on the other hand, there may be gaps or errors in memory as well as for the positive and negative life events.

  5. Potential reduced exposure products (PREPs) in industry trial testimony. (United States)

    Wayne, Geoffrey Ferris


    To identify patterns in trial testimony that may reflect on the intentions or expectations of tobacco manufacturers with regard to the introduction of potential reduced exposure products (PREPs). Research was conducted using the Deposition and Trial Testimony Archive (DATTA) collection of trial testimony and depositions housed online at Tobacco Documents Online ( Relevant testimony was identified through full-text searches of terms indicating PREPs or harm reduction strategies. The role and function of PREPs in testimony were classified according to common and contrasting themes. These were analysed in the context of broader trial arguments and against changes in time period and the market. Analysis of testimony suggests that the failure of PREPs in the market tempered initial industry enthusiasm and made protection of the conventional cigarette market its major priority. The "breakthrough" character of PREPs has been de-emphasised, with trial arguments instead positioning PREPs as simply another choice for consumers. This framework legitimises the sale of conventional brands, and shifts the responsibility for adoption of safer products from the manufacturer to the consumer. Likewise, testimony has abandoned earlier dramatic health claims made with regard to PREPs, which had undermined industry arguments regarding efforts to reduce harm in conventional products. More recent testimony advocates the broad acceptance of independent guidelines that would validate use of health claims and enable the industry to market PREPs to consumers. Trial testimony reflects the changing role and positioning of PREPs by the tobacco industry. The findings are of particular importance with regard to future evaluation and potential regulation of reduced harm products.

  10. A semantic solution to the problem with aesthetic testimony


    Andow, James


    There is something peculiar about aesthetic testimony. It seems more difficult to gain knowledge of aesthetic properties based solely upon testimony than it is in the case of other types of property. In this paper, I argue that we can provide an adequate explanation at the level of the semantics of aesthetic language, without defending any substantive thesis in epistemology or about aesthetic value/judgement. If aesthetic predicates are given a non-invariantist semantics, we can explain the s...

  11. Comparison of plaintiff and defendant expert witness qualification in malpractice litigation in otolaryngology. (United States)

    Eloy, Jean Anderson; Svider, Peter F; Patel, Dharti; Setzen, Michael; Baredes, Soly


    Malpractice litigation contributes to rising health care costs in the United States. The role of expert witness testimony has been controversial in the past, with medical professional societies issuing statements regarding ethical obligations of physicians. Our objectives were to examine the relative qualifications of expert witnesses testifying on behalf of plaintiffs vs defendants. Analysis of expert witness and physician demographic data available on several databases. The Westlaw legal database (Thomson Reuters, New York, New York) was searched for otolaryngologist expert witness testimony. Length of experience, practice setting, and subspecialty training information were obtained from hospital, practice, departmental, and state licensing board sites. Scholarly impact was assessed using calculation of the h-index from the Scopus database. Plaintiff expert witnesses had significantly less experience than those testifying for defendants (31.8 vs 35.4 years, P = .047) and lower scholarly impact (h = 6.3 vs 10, P = .045). A significantly higher proportion of defendant witnesses were in academic practice (49.3% vs 31.7%, P = .042). No differences were detected in postresidency fellowship training patterns. Upon comparison of otolaryngologist expert witnesses, practitioners testifying on behalf of plaintiffs had statistically fewer years of experience, had a lower scholarly impact, and were less likely to work in an academic setting. Otolaryngologists who repeatedly served as expert witnesses were more likely to be testifying on behalf of plaintiffs than defendants. Professional societies need to frequently update guidelines on expert witness testimony and address the ethical obligations of practitioners.

  12. Addressing challenges to MMPI-2-RF-based testimony: questions and answers. (United States)

    Ben-Porath, Yossef S


    Introduction of a new version of a psychological test brings with it challenges that can be accentuated by the adversarial nature of the legal process. In the case of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), these challenges can be addressed by becoming familiar with the rationale for and the methods used in revising the inventory, the information contained in the test manuals, and the growing peer-reviewed literature on the test. Potential challenges to MMPI-2-RF-based testimony are identified in this article and discussed in question and answer format. The questions guiding this discussion are based on the Daubert factors, established in 1993 by the US Supreme Court as criteria for gauging the scientific validity of proffered expert testimony. The answers to these questions apply more broadly to testimony in depositions, pre-trial hearings, and at trial. Consideration of the MMPI-2-RF in light of the Daubert factors indicates that the instrument has been subjected to extensive empirical testing and that a substantial peer-reviewed literature is available to guide and support its use. Information about the known and potential rate of error associated with MMPI-2-RF scores is available, and standard procedures for administration, scoring, and interpretation of the inventory are detailed in the test administration manual. Indicators of MMPI-2-RF acceptance can be cited, and criticisms of the MMPI-2-RF can be addressed with information available in the test documents and an extensive, modern, and actively growing peer-reviewed literature.

  14. Early testimonial learning: monitoring speech acts and speakers. (United States)

    Stephens, Elizabeth; Suarez, Sarah; Koenig, Melissa


    Testimony provides children with a rich source of knowledge about the world and the people in it. However, testimony is not guaranteed to be veridical, and speakers vary greatly in both knowledge and intent. In this chapter, we argue that children encounter two primary types of conflicts when learning from speakers: conflicts of knowledge and conflicts of interest. We review recent research on children's selective trust in testimony and propose two distinct mechanisms supporting early epistemic vigilance in response to the conflicts associated with speakers. The first section of the chapter focuses on the mechanism of coherence checking, which occurs during the process of message comprehension and facilitates children's comparison of information communicated through testimony to their prior knowledge, alerting them to inaccurate, inconsistent, irrational, and implausible messages. The second section focuses on source-monitoring processes. When children lack relevant prior knowledge with which to evaluate testimonial messages, they monitor speakers themselves for evidence of competence and morality, attending to cues such as confidence, consensus, access to information, prosocial and antisocial behavior, and group membership. © 2015 Elsevier Inc.

  15. The influence of expert testimony on legal decisions regarding the civil liability of doctors

    Directory of Open Access Journals (Sweden)



    Full Text Available Nosocomial infection is notoriously one of the primary problems faced by healthcare insti-tutions and by professionals who work for them. This fact is demonstrated by the growing number of legal actions proposed in the legal system by patients and users of the health care system. Because of this scenario, the phenomenon of civil liability has arisen in cases of noso-comial infection. The legal implications of this phenomenon are varied and involve issues of the institutional environment and of professional conduct. Thus, the current study seeks to analyze the literature on the decisions taken by Brazilian courts regarding civil liability in cases of nosocomial infection. Conceptual aspects that define this healthcare problem are listed, as are the types of civil liability, the legal directives that guide conduct regarding this topic, and the decisions of Brazilian courts that consider civil liability in these cases. It was determined that the courts have been supported by the distinction between objective civil liability and subjective civil liability; additionally, it was determined that these courts are guided by the understanding of the existing service relationship between the institution or health care professional and the patient or user of the health care system.

  16. Expert witness perceptions of bias in experts. (United States)

    Commons, Michael Lamport; Miller, Patrice Marie; Gutheil, Thomas G


    A pilot study of perceptions of different sources of expert bias, as well as of personal investment in case outcomes, was performed among attendees at a workshop at an annual meeting of the American Academy of Psychiatry and the Law. Participants were asked to rate hypothetical responses by experts to various case outcomes and the biasing potential of different kinds of situations for opposing or other experts. A factor analysis produced two factors. Factor 1 included questions about situations that were obviously biasing (such as working only for the defense). Factor 2 included questions assessing the potential of certain situations to cause bias in experts, or how likely experts thought other experts were to be biased. In general, experts identified only four areas to be overtly biasing. All occurred within situations in which experts worked only for one or the other side of civil or criminal cases. Experts otherwise thought other experts were reasonably bias free and well able to compensate for any bias when it occurred. The data suggest that experts may deal with bias by turning down cases that may cause them personal discomfort.

  2. Testimony ceremonies in Asia: Integrating spirituality in testimonial therapy for torture survivors in India, Sri Lanka, Cambodia, and the Philippines (United States)

    Agger, Inger; Igreja, Victor; Kiehle, Rachel; Polatin, Peter


    This study explores the therapeutic implications of including culturally adapted spiritual ceremonies in the process of testimonial therapy for torture survivors in India, Sri Lanka, Cambodia, and the Philippines. Data were collected through an action research process with Asian mental health and human rights organizations, during which the testimonial method was reconceptualized and modified to include four sessions. In the first two sessions, community workers assist survivors in the writing of their testimony, which is their narrative about the human rights violations they have suffered. In the third session, survivors participate in an honour ceremony in which they are presented with their testimony documents. In the fourth session, the community workers meet with the survivors for a reevaluation of their well-being. The honour ceremonies developed during the action research process came to employ different kinds of symbolic language at each site: human rights (India), religious/Catholic (Sri Lanka), religious/Buddhist (Cambodia), and religious/Moslem (Philippines). They all used embodied spirituality in various forms, incorporating singing, dancing, and religious purification rituals in a collective gathering. We suggest that these types of ceremonies may facilitate an individual’s capacity to contain and integrate traumatic memories, promote restorative self-awareness, and engage community support. Additional research is needed to determine the method’s applicability in other sociopolitical contexts governed by more Western-oriented medical traditions. PMID:22637721

  5. [The Testimony. Contributions to the Construction of Historical Memory]. (United States)

    Roldán, Ismael


    Testimony is a complex act that contributes significantly to the elaboration of mourning, both individually and on a collective level. This is the central idea that is discussed in the text, using as a basis, the results of research conducted as a pilot intervention in the year 2010 for Visible Victims Foundation, and was then replicated in four other regions. In 1998 the National Liberation Army attacked the pipeline OCENSA causing severe damage to the people of Machuca (Segovia, Antioquia). In 2010 the psychologist Ligia Rascovsky implemented an intervention strategy to support the construction of individual and collective memory among survivors of the attack, who, in addition to serious injuries, suffered physical and psychosocial after effects such as post-traumatic stress disorder (PTSD). The results of this work are used to understand the relevance of the testimony in the psychosocial recovery processes, which is a major challenge for Colombian society today. The type of study was psychosocial intervention in 43 adults of both sexes, Machuca residents who were affected by the bombing, and agreed to voluntarily participate in designed workshops. The workshops followed experiential type techniques (psychodrama, psycho-fantasies, etc.), in which the purpose was to identify the damage by developing testimonial memory of what happened. The workshops express the emotions of grief, recognize the injustice of suffering, fight memory defense that justifies violence and raising awareness of human rights. It also facilitated the process of dignity, empowerment and security in personal and collective reconstruction. In expressing their memoirs thus, they could be free from fear and gain more confidence in themselves as individuals and as a social group, as seen in the formation of individual leadership. These results are the basis of the discussion presented. In this context it has been found that the testimonial narrative is an instrument of personal and social healing

  6. Neuropsychologist experts and neurolaw: cases, controversies, and admissibility challenges. (United States)

    Kaufmann, Paul M


    Clinical neuropsychologists engage increasingly in forensic consulting activities because such expert opinions are generally relevant, reliable and helpful in resolving certain legal claims, especially those related to traumatic brain injury. Consequently, practitioners of law, medicine and psychology would benefit from understanding the nature of neuropsychological evidence, the standards for its admissibility, and its expanding role in neurolaw. This article reviews important evidentiary rules regulating relevance, preliminary questions, and expert testimony, while tracing federal key court decisions and progeny. Civil and criminal cases are detailed to illustrate the application of these rules and case law to neuropsychological evidence, with suggestions for overcoming motions to exclude such evidence. Expert neuropsychologists have a role in forensic consultation on brain trauma cases, even as the interdisciplinary dialog and understanding among law, medicine, and psychology continues to expand.

  8. Trauma, memory, testimony: phenomenological, psychological, and ethical perspectives

    Directory of Open Access Journals (Sweden)

    Claudia Welz


    Full Text Available How can severely traumatized persons re-present the past and its impact on the present if (due to blackout, repression, or dissociation they could not witness what they went through, or can hardly recall it? Drawing on Holocaust testimonies, this article explores the crisis of witnessing constituted by the Shoah and, more generally, problems of integrating and communicating traumatic experiences. Phenomenological, psychological, and ethical perspectives contribute to a systematic investigation of the relation between trauma, memory and testimony. I will argue that preserving personal continuity across the gap between past and present presupposes not only an ‘inner witness’ – which can, according to a long philosophical tradition, be identified with a person’s conscience – but also a social context in which one is addressed and can respond. An attentive listener can bear witness to the witness by accepting the assignation of responsibility implied in testimonial interaction, and thereby support the dialogic restitution of memory and identity.

    Full Text Available While differences in witness narratives due to different interviewers may have implications for their credibility in court, this study considers how investigative interviews by different parties to the proceedings, as well as the gender and nationality of interviewers, can influence the testimony of witnesses in court who share comparable traumatic experiences. The foundation of the analysis was answers given to judges, prosecutors, civil party lawyers and defence lawyers in the Extraordinary Chambers in the Courts of Cambodia (ECCC located in Phnom Penh. Transcribed testimonies of 24 victim witnesses and civil parties which were translated from Khmer into English were analysed using a computer-based text analysis program, the Linguistic Inquiry and Word Count (LIWC. Results showed that when answering questions by females, witnesses used significantly more cognitive process words. When interviewed by international rather than by Cambodian parties to the proceeding witness accounts were composed of significantly more verbal expressions of affective processes and of perceptual processes. Furthermore, witnesses used most cognitive and affective process words during the interview by civil party lawyers and defence lawyers. These results may be due to a prior supportive relationship between civil parties and their lawyers and due to a more interrogative question style by the defence lawyers, who attempt to undermine the credibility of the interviewed witnesses. Data shows that LIWC analysis is an appropriate method to examine witness accounts and, therefore, contributes to a better understanding of the complex relationship between testimony in events under litigation and credibility.

  10. Sexual science and sexual forensics in 1920s Germany: Albert Moll as (S)expert. (United States)

    Conn, Matthew


    Using court records involving the expert testimony of the Berlin sexologist Albert Moll, my article demonstrates that during the early 1920s a shift in the 'epistemologies of justice' concerning the adjudication of sex crimes took place within German courtrooms. Namely, presiding judges considered a greater number of sexual acts as punishable, despite no change in the laws themselves. Central to my argument is the role of expert testimony in practice and its critical reception. By focusing upon the rhetorical strategies presented by attorneys, judges and expert witnesses (as well as defendants themselves and their relatives), it illustrates the functions of expert and tacit knowledge in court, which were often not mutually exclusive. Moll's stature also enabled him to translate his scientific-medical expertise into state support for his testimonies, as well as the rebuilding of an international community of sexological authorities. It was only under Moll's leadership that the First International Sexology Congress could take place in 1926, an event that marked the apex of his prestige.

  12. Expert status and performance.

    Directory of Open Access Journals (Sweden)

    Mark A Burgman

    Full Text Available Expert judgements are essential when time and resources are stretched or we face novel dilemmas requiring fast solutions. Good advice can save lives and large sums of money. Typically, experts are defined by their qualifications, track record and experience. The social expectation hypothesis argues that more highly regarded and more experienced experts will give better advice. We asked experts to predict how they will perform, and how their peers will perform, on sets of questions. The results indicate that the way experts regard each other is consistent, but unfortunately, ranks are a poor guide to actual performance. Expert advice will be more accurate if technical decisions routinely use broadly-defined expert groups, structured question protocols and feedback.

  13. [Quality of anesthesiological expert opinion in medical claims cases]. (United States)

    Hachenberg, T; Neu, J; Werner, S; Wiedemann, D; Schaffartzik, W


    Expert opinions have an important place for expert testimony in medical disputes. The report should contain a summary about facts and causality between the damage and the medical treatment in question as well as describe the current medical standard. The fulfillment of scientific criteria was investigated in 179 anesthesiological expert opinions from 150 arbitration cases. Anesthesiological expert reports (2005-2007) of the Arbitration Board of the North German Medical Associations were analyzed in terms of structure, general form of assessment and scientific substantiation of statements. Patient damage was confirmed in 76%, treatment failure in 29% and negligent malpractice in 17% of the reports. In 78% of the reports the facts were presented correctly and in 64% the question was answered whether the incident would have occurred even during adequate and professional action. Conclusive statements about the causality between the damage and the medical treatment in question were available only in 60% of the reports. The study findings suggest that anesthesia expert reports present a high incidence of non-scientific claims. The development of guidelines for expert witnesses by the medical societies is urgently recommended.

  14. Forensic experts' perceptions of expert bias. (United States)

    Commons, Michael Lamport; Miller, Patrice Marie; Li, Eva Yujia; Gutheil, Thomas Gordon


    How do expert witnesses perceive the possible biases of their fellow expert witnesses? Participants, who were attendees at a workshop at the American Academy of Psychiatry and Law were asked to rate for their biasing potential a number of situations that might affect the behavior of an opposing expert. A Rasch analysis produced a linear scale as to the perceived biasing potential of these different kinds of situations from the most biasing to the least biasing. Working for only one side in both civil and criminal cases had large scaled values and also were the first factor. In interesting contrast, a) an opposing expert also serving as the litigant's treater and b) an opposing expert being viewed as a "hired gun" (supplying an opinion only for money) were two situations viewed as not very biasing. Order of Hierarchical Complexity also accounted for items from the 1st, 2nd and 3rd factors. The result suggests that the difficulty in understanding the conceptual basis of bias underlies the perception of how biased a behavior or a situation is. The more difficult to understand the questionnaire item, the less biasing its behavior or situation is perceived by participants. Copyright © 2012 Elsevier Ltd. All rights reserved.

  17. Reproductive Travel to Ghana: Testimonies, Transnational Relationships, and Stratified Reproduction. (United States)

    Gerrits, Trudie


    In this article, I address reproductive travel to Ghana, based on research conducted in two private fertility clinics. Both clinics attract clients from West African countries as well as Ghanaian people living in the US and Europe. Their motivations to visit these clinics include positive "testimonies" about treatment results, "bioavailability" of matching donor material and surrogates, lower treatment costs and the circumvention of restricting regulations in the country of residence. Communication technologies are central in facilitating reproductive travel. Finally, I argue that the "international choreographies" of reproductive travel are co-shaped by the unique biographies and transnational relationships of the people involved.

  18. Introduction to expert systems

    Energy Technology Data Exchange (ETDEWEB)

    Jackson, P.


    Expert systems have become one of the most exciting applications within the domain of artificial intelligence. Further interest has been provoked by Japan's Fifth Generation Project, which identifies expert or knowledge-based systems as a key element in the computer systems of the future. This book presents an introduction to expert systems at a level suited to the undergraduate student and the interested layman.

  19. Misconceptions about childhood sexual abuse and child witnesses: Implications for psychological experts in the courtroom. (United States)

    Zajac, Rachel; Garry, Maryanne; London, Kamala; Goodyear-Smith, Felicity; Hayne, Harlene


    Recent changes to the law in New Zealand have led to a marked increase in experts being called to give evidence in cases of alleged child sexual abuse. Here we outline some of the common misconceptions that are held by expert witnesses in these cases and we review research on patterns of abuse disclosure and retraction, symptoms of abuse, external influences on children's reports, and experts' ability to distinguish true from false reports. We also consider what experts can say about memory that has relevance for these cases. We conclude that many long-held notions of child sexual abuse and children's testimony that make their way into our courtrooms are not supported by empirical research, raising questions about who is-and who is not-qualified to act as an expert witness.

    Full Text Available A proposed protocol for evaluating the statements and identifications made by the potential victims of crimes is presented in this paper. The protocol, called HELPT, is part of a holistic approach to evaluating the testimony that takes into account all of the possible factors of influence: encoding, retention and recovery. Among these factors, the following will be relevant: a the ability of victims to testify, as well as cognitive processes of attention, perception, memory and language; b the specific characteristics of the offence; c the history of the event and its consequences; d other factors that might affect the quality and accuracy of the statements and identifications, such as the number of times the victim had to tell what happened, the methods used to obtain the story and possibilities of suggestion. The method includes specific procedures for exhaustive analysis of the testimonies and for the formulation and testing of hypotheses (Scott & Manzanero, 2015, the evaluation of the competence to testify (Contreras, Silva, & Manzanero, 2015 and the obtaining of statements (González, Muñoz, Sotoca, & Manzanero, 2013.

  4. Avoiding ipse dixit mislabeling: post-Daubert approaches to expert clinical opinions. (United States)

    Gutheil, Thomas G; Bursztajn, Harold


    Recent Supreme Court decisions emphasize the need to regulate the admissibility of expert testimony by means of standards that require opinions to go beyond ipse dixit--that is, that are based on more than the fact that the expert said it. The authors discuss subtextual themes underlying this issue and suggest approaches to attaining expert clinical opinions that reduce the likelihood of being mislabeled as ipse dixit contributions. The approach involves providing substantiation of testimony by offering a reliable methodologic basis for communicating the relevant opinion in a thoughtful and intellectually rigorous manner. A model is offered, emphasizing a process approach to opinion formulation and reformulation prior to deposition and trial. This approach addresses not only the Supreme Court's current focus on moving expert opinion beyond ipse dixit, but also such concerns as possible distortions of an expert opinion in the adversarial process. Since judicial determinations may vary depending on many factors, however, even the most careful process of opinion formulation cannot guarantee admissibility. The article assumes a general familiarity among forensic readers with the Federal Rules of Evidence and the recent series of Supreme Court decisions in this area.

  7. Bleeding Mud: The Testimonial Poetry of Hurricane Mitch in Nicaragua

    Directory of Open Access Journals (Sweden)

    Erin S Finzer


    Full Text Available Beginning with Rubén Darío, Nicaragua has long prided itself in being a country of poets. During the Sandinista Revolution, popular poetry workshops dispatched by Minister of Culture Ernesto Cardenal taught peasants and soldiers to write poetry about everyday life and to use poetry as a way to work through trauma from the civil war. When Hurricane Mitch--one of the first superstorms that heralded climate change--brought extreme flooding to Nicaragua in 1998, poetry again served as a way for victims to process the devastation. Examining testimonial poetry from Hurricane Mitch, this article shows how the mud and despair of this environmental disaster function as palimpsests of conquest and imperial oppression.

  8. The Griffiths Question Map: A Forensic Tool For Expert Witnesses' Assessments of Witnesses and Victims' Statements. (United States)

    Dodier, Olivier; Denault, Vincent


    Expert witnesses are sometimes asked to assess the reliability of young witnesses and victims' statements because of their high susceptibility to memory biases. This technical note aims to highlight the relevance of the Griffiths Question Map (GQM) as a professional forensic tool to improve expert witnesses' assessments of young witnesses and victims' testimonies. To do so, this innovative question type assessment grid was used to proceed to an in-depth analysis of the interview of an alleged 13-year-old victim of a sexual assault and two rapes. Overall, the GQM stressed how the interview was mainly conducted in an inappropriate manner. The results are examined with regard to scientific knowledge on young witnesses and victims' memory. Finally, it is argued that expert witnesses in inquisitorial systems might use the GQM while encountering difficulties to fulfill the legal standards for expert evidence in adversarial systems because of the lack of studies regarding its reliability. © 2017 American Academy of Forensic Sciences.

  9. What defines an Expert? - Uncertainty in the interpretation of seismic data (United States)

    Bond, C. E.


    Studies focusing on the elicitation of information from experts are concentrated primarily in economics and world markets, medical practice and expert witness testimonies. Expert elicitation theory has been applied in the natural sciences, most notably in the prediction of fluid flow in hydrological studies. In the geological sciences expert elicitation has been limited to theoretical analysis with studies focusing on the elicitation element, gaining expert opinion rather than necessarily understanding the basis behind the expert view. In these cases experts are defined in a traditional sense, based for example on: standing in the field, no. of years of experience, no. of peer reviewed publications, the experts position in a company hierarchy or academia. Here traditional indicators of expertise have been compared for significance on affective seismic interpretation. Polytomous regression analysis has been used to assess the relative significance of length and type of experience on the outcome of a seismic interpretation exercise. Following the initial analysis the techniques used by participants to interpret the seismic image were added as additional variables to the analysis. Specific technical skills and techniques were found to be more important for the affective geological interpretation of seismic data than the traditional indicators of expertise. The results of a seismic interpretation exercise, the techniques used to interpret the seismic and the participant's prior experience have been combined and analysed to answer the question - who is and what defines an expert?

  10. Soft Expert Sets

    Directory of Open Access Journals (Sweden)

    Shawkat Alkhazaleh


    Full Text Available In 1999, Molodtsov introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty. Many researchers have studied this theory, and they created some models to solve problems in decision making and medical diagnosis, but most of these models deal only with one expert. This causes a problem with the user, especially with those who use questionnaires in their work and studies. In our model, the user can know the opinion of all experts in one model. So, in this paper, we introduce the concept of a soft expert set, which will more effective and useful. We also define its basic operations, namely, complement, union intersection AND, and OR. Finally, we show an application of this concept in decision-making problem.

  13. Battered woman syndrome testimony in Canada: its development and lingering issues. (United States)

    Tang, Kwong-leung


    This article examines the status of battered woman syndrome (BWS) testimony in Canadian courts and assesses the impact of the leading decision, Regina (R.) v. Lavallee. Acknowledging the test of reasonableness in criminal trials was constructed on a male model, the Supreme Court in Lavallee corrected the gendered interpretation of women in abusive relationships by admitting the BWS evidence. Feminist legal scholars questioned whether Lavallee had succeeded in dispelling the stereotypes around battered women. These concerns were partially addressed in R. v. Malott, but some tough issues remain: applying the reasonableness test to women of color and the narrow base of BWS evidence. Some directions are discussed: discarding BWS testimony, framing a redefined and expanded BWS testimony, introducing a new defense based on self-preservation, and adopting an alternative interpretative frame such as "coercive control." The strengthening of BWS testimony would call for the judges' referencing of latest empirical research on battered women.

  15. Comprehension, Acceptance and Justification: Applying pragmatics to the epistemology of testimony


    Pedersen, Kim Phillips


    The main question discussed in current debates about the epistemology of testimony concerns whether the justification of testimonial beliefs is inferential or non-inferential. This thesis offers a novel argument for inferentialism, the former view. It does so through, firstly, assuming a widely shared view about the psychology of comprehension – the inferential model of communication – along with widely shared views about the epistemic basing relation and inferential justification, and then, ...

  16. Il valore della testimonianza – The Value of Testimony

    Nicla Vassallo


    Full Text Available The following text is from my book Teoria della conoscenza published by Laterza some years ago. I have chosen to offer it here, in memory of my friend and colleague Flavio Baroncelli, for three basic reasons. First of all, more than twenty years ago, Flavio offered to be the supervisor of my graduate thesis on an epistemological theme in modern philosophy. I have not forgotten that possibility and have in recent times come to reflect upon both the type of epistemology and the philosophers that were beloved by Flavio. The text which follows these introductory remarks is a testament to this. Secondly, when he knew that I was interested in the epistemology of testimony, Flavio urged me to go on, because of the importance of that topic not only for general epistemology, but also for many other branches of philosophy. Thirdly, on the occasion of the publication of Teoria della conoscenza, Flavio participated on the round table in which it was presented to the public and had something like this to say: "I read the whole book with the same breath, as it was a detective story". In his memory, I cannot but hope to write other "detective stories".

  17. Accumulated Testimony: Layering French Girls’ Diaries on the Algerian Exodus

    Directory of Open Access Journals (Sweden)

    Amy L Hubbell


    Full Text Available In 1997, French-Algerian author Leïla Sebbar published an illustrated children’s book, J’étais enfant en Algérie, juin 1962 (‘I was a child in Algeria, June 1962’ in which she creates the fictional account of a young girl from the interior of Algeria leaving her home during the great exodus of the French just prior to Algerian independence. Using the genre of diary writing, Sebbar’s text reads as testimonial of fleeing their country for a homeland they do not know. Although this text is intimate, Sebbar relies on accumulated scraps of collective experience that, when joined to her own, fill in the absence of her homeland. In 2013, French artist Nicole Guiraud published her personal diaries kept before and during her exodus from Algeria from April to July 1962. Her raw representation of traumatic upheaval is couched in a rich paratext including artwork, photographs, and German translations, that simultaneously intensifies her account and distracts the reader from the extreme pain behind her words. In this article I demonstrate how fictional and real accounts published in very different historical contexts convey the exodus experienced by almost one million individuals and how each author deploys a layering technique to simultaneously draw in and distance the reader from extraordinarily painful personal experience.

  18. Credibility assessment of testimonies provided by victims with intellectual disabilities

    Directory of Open Access Journals (Sweden)

    Antonio L. MANZANERO


    Full Text Available One of the main obstacles in the way of access to justice for the victims with intellectual disability comes from the stereotypes referred to their ability to produce a statement at police legal procedures, with the consequence that some consider their statements less reliable than the rest of the victims, and others considerate their statements more reliable given their inability to create complex lies. This article reviews three of the most recent studies done by the UCM group of Psychology of Testimony, with the objective of analyzing the role of experience and intuition in the evaluation of credibility in people with intellectual disability (ID, and also it aims to prove whether the credibility analysis procedures such as Reality Monitoring (RM and Statement Validity Assessment (SVA would be valid procedures to discriminate between real and false statements within these collectives. From the results of these studies, it can be deducted that experience may not seem to be enough in order to discriminate between real and simulated victims, but analyzing the characteristics of the statements as the only indicator doesn’t seem to be enough either. As an alternative, the general procedure HELPT is proposed for the evaluation of credibility of people with ID.

  19. Capital Expert System (United States)

    Dowell, Laurie; Gary, Jack; Illingworth, Bill; Sargent, Tom


    Gathering information, necessary forms, and financial calculations needed to generate a "capital investment proposal" is an extremely complex and difficult process. The intent of the capital investment proposal is to ensure management that the proposed investment has been thoroughly investigated and will have a positive impact on corporate goals. Meeting this requirement typically takes four or five experts a total of 12 hours to generate a "Capital Package." A Capital Expert System was therefore developed using "Personal Consultant." The completed system is hybrid and as such does not depend solely on rules but incorporates several different software packages that communicate through variables and functions passed from one to another. This paper describes the use of expert system techniques, methodology in building the knowledge base, contexts, LISP functions, data base, and special challenges that had to be overcome to create this system. The Capital Expert System is the successful result of a unique integration of artificial intelligence with business accounting, financial forms generation, and investment proposal expertise.

  20. Narrative Rhetoric in Expert Reports: A Case Study

    Directory of Open Access Journals (Sweden)

    Clive Baldwin


    Full Text Available Rhetoric within narratives has been the focus of attention for several well-known scholars in the field of literary criticism. While other forms of writing, such as professional reports, have been analysed through the lens of narrative, the rhetoric therein has received little attention. Although the official position is that UK child protection proceedings are inquisitorial and evidence-based, it is possible to identify rhetorical practices in both narratives of professional reports and the court proceedings. Drawing on Aristotle’s Rhetoric, I will analyse rhetorically the expert pediatric reports presented in a case of alleged Munchausen syndrome by proxy, focusing in particular on ethos and pathos. In so doing, I will seek to illustrate how rhetoric permeates child protection proceedings and indicate how rhetorical analysis might aid the evaluation of evidence and testimony.

  3. Bioethics for Technical Experts (United States)

    Asano, Shigetaka

    Along with rapidly expanding applications of life science and technology, technical experts have been implicated more and more often with ethical, social, and legal problems than before. It should be noted that in this background there are scientific and social uncertainty elements which are inevitable during the progress of life science in addition to the historically-established social unreliability to scientists and engineers. In order to solve these problems, therefore, we should establish the social governance with ‘relief’ and ‘reliance’ which enables for both citizens and engineers to share the awareness of the issues, to design social orders and criterions based on hypothetical sense of values for bioethics, to carry out practical use management of each subject carefully, and to improve the sense of values from hypothetical to universal. Concerning these measures, the technical experts can learn many things from the present performance in the medical field.

    CERN Document Server

    Ionita, C


    The ALICE experiment at CERN employs a number of human operators (shifters), who have to make sure that the experiment is always in a state compatible with taking Physics data. Given the complexity of the system and the myriad of errors that can arise, this is not always a trivial task. The aim of this paper is to describe an expert system that is capable of assisting human shifters in the ALICE control room. The system diagnoses potential issues and attempts to make smart recommendations for troubleshooting. At its core, a Prolog engine infers whether a Physics or a technical run can be started based on the current state of the underlying sub-systems. A separate C++ component queries certain SMI objects and stores their state as facts in a Prolog knowledge base. By mining the data stored in dierent system logs, the expert system can also diagnose errors arising during a run. Currently the system is used by the on-call experts for faster response times, but we expect it to be adopted as a standard tool by reg...

  8. [Expert Opinions in Court: Liability of the Expert]. (United States)

    Schiltenwolf, Marcus; Beckmann, Nickolas; Gaidzik, Peter


    Experts in criminal, civil and, increasingly, in social court cases have to present their expert opinions in court. This should be regarded not only as a burden, even if this may at times appear superfluous to the expert, perhaps because the discussion is mere repetition of the opinion he has already written, or because the questions appear to be biased against the expert. Nonetheless, the expert is always advised to appear calm and objective during the interrogation by judges and parties or participants and their legal representatives, and should not allow himself or herself to be provoked by questioning. Furthermore, it may be necessary to correct the written expert statement in the course of the interrogation, but this can be a sign of a truly competent medical expert. The expert consulted can be held liable for adverse health effects resulting from the interrogation and investigation, as well as for deliberate or grossly faulty reports.

  9. Testimonial therapy. A pilot project to improve psychological wellbeing among survivors of torture in India. (United States)

    Agger, Inger; Raghuvanshi, Lenin; Shabana, Shirin; Polatin, Peter; Laursen, Laila K


    In developing countries where torture is perpetrated, there are few resources for the provision of therapeutic assistance to the survivors. The testimonial method represents a brief cross-cultural psychosocial approach to trauma, which is relatively easy to master. The method was first described in Chile in 1983 and has since been used in many variations in different cultural contexts. In this project the method has been supplemented by culture-specific coping strategies (meditation and a delivery ceremony). A pilot training project was undertaken between Rehabilitation and Research Centre for Torture victims (RCT) in Copenhagen, Denmark, and People's Vigilance Committee for Human Rights (PVCHR) in Varanasi, India, to investigate the usefulness of the testimonial method. The project involved the development of a community-based testimonial method, training of twelve PVCHR community workers, the development of a manual, and a monitoring and evaluation (M&E) system comparing results of measures before the intervention and two to three months after the intervention. Twenty-three victims gave their testimonies under supervision. In the two first sessions the testimony was written and in the third session survivors participated in a delivery ceremony. The human rights activists and community workers interviewed the survivors about how they felt after the intervention. After testimonial therapy, almost all survivors demonstrated significant improvements in overall WHO-five Well-being Index (WHO-5) score. Four out of the five individual items improved by at least 40%. Items from the International Classification of Functioning, Disability and Health (ICF) showed less significant change, possibly because the M&E questionnaire had not been well understood by the community workers, or due to poor wording, formulation and/or validation of the questions. All survivors expressed satisfaction with the process, especially the public delivery ceremony, which apparently became a

  10. Narrative characteristics of genocide testimonies predict posttraumatic stress disorder symptoms years later. (United States)

    Ng, Lauren C; Ahishakiye, Naphtal; Miller, Donald E; Meyerowitz, Beth E


    Cognitive theories of posttraumatic stress disorder (PTSD) suggest that trauma narratives that make greater use of somatosensory, perceptual, and negative emotion words may be indicators of greater risk of PTSD symptoms (Ehlers & Clark, 2000). The purpose of this study was to analyze whether the way that survivors of the 1994 Rwandan Genocide against the Tutsi naturally construct genocide testimonies predicts PTSD symptoms 6 years later. One hundred orphaned heads of household (OHH) who were members of a community association gave testimonies about their genocide experiences in 2002. In 2008, PTSD symptoms of 61 of the original OHH were assessed using a genocide-specific version of the Impact of Events Scale-Revised (Weiss & Marmar, 1997). Experienced genocide events were coded from the genocide testimonies, and the types of words used in the testimonies were analyzed using the Linguistic Inquiry and Word Count program (Pennebaker, Chung, Ireland, Gonzales, & Booth, 2007). Pearson correlations and path analyses assessed the relationships between variables. After accounting for genocide events, touching positively predicted avoidance, and sadness negatively predicted hyperarousal. Sensory descriptions of traumatic experiences in trauma narratives may signify higher risk for mental health problems whereas expressions of sadness may indicate emotional processing and better mental health. Analyzing genocide testimonies may help identify survivors at the highest risk of developing PTSD symptoms, even among a group of survivors who have arguably suffered some of the most severe genocide experiences.

    Full Text Available The testimony of pre-school children is, in many cases, the main and only evidence in criminal proceedings. Memory and language are two main components in the statement of the child and they require special analysis, not only because of the important role they play, but also because of the relationship between the two capacities. The vulnerability of memory and its ability to be altered by suggestions, as well as the variability of language development in the 3- to 6-year-old child, are two factors that influence the collection of testimony. These factors, together with the interviewer’s skill in adapting the interview to the child, may obtain reliable information that is free of subjectivity and that will facilitate the investigation of the allegations. This article presents an overview of both capabilities, language and memory, from the perspective of child witness testimony as evidence in criminal proceedings.

  16. [Historical connection between memory and testimony psychology by an experimental study of Seiichi Terada in Japan]. (United States)

    Wakabayashi, Kosuke; Sato, Tatsuya


    In Japan, Seiichi Terada (1884-1922) was the first psychologist who applied psychological knowledge to the field of law, working in collaboration with the law professor Eiich Makino (1878-1970). Terada's work was mainly in the tradition of clinical psychology, although in his 1915 paper titled "How useful are testimonies?" he described a set of seven experiments concerned with the empirical relationship between eyewitness testimony and memory. This is probably the first experimental study of law and psychology carried out in Japan. This article introduces Terada's history as a psychologist, and his collaboration with Makino, followed by explanation of their experiments. Finally, we discuss perspectives on testimony research in consideration of Terada's approach.

  17. An Analysis of Malpractice Litigation and Expert Witnesses in Plastic Surgery. (United States)

    Therattil, Paul J; Chung, Stella; Sood, Aditya; Granick, Mark S; Lee, Edward S


    Objective: Expert witness testimony is crucial for juror decision making. The goals of this study were to examine the trends in malpractice litigation in plastic surgery and to examine the characteristics of expert witnesses in litigation. Methods: The Westlaw legal database was queried for jury verdict and settlement reports related to plastic surgery cases from 2009 to 2015. Cases were examined for expert witness testimony, procedure performed, alleged injury, cause of action, verdict, and indemnity payments. Results: Ninety-three relevant cases were examined. Mean plaintiff award was $1,036,469, whereas mean settlement was $633,960. The most commonly litigated procedures involved breast surgery (34.4%), liposuction (18.3%), and body contouring (14.0%). Cases involving body contouring (risk ratio [RR] = 1.48; 95% CI, 1.04-2.10) were more likely to result in favor of the defendant, whereas cases involving breast surgery (RR = 0.27; 95% CI, 0.13-0.57) were more likely to result in favor of the plaintiff (P < .05). Cases in which there was claimed pain (RR = 1.22; 95% CI, 1.01-1.48) or emotional distress (RR = 1.38; 95% CI, 1.11-1.70) were more likely to result in favor of the plaintiff (P < .05). The party of a lawsuit was more likely to win the case if its expert witness was a plastic surgeon (P < .05). Conclusion: Plastic surgery litigation tends to favor defendants. Most litigation involves breast surgery, liposuction, and body contouring. The type of procedure and alleged claim affect case success. Parties with a plastic surgeon as an expert witness tend to be more successful in litigation.

    Morton, Rebecca; Tyran, Jean-Robert

    in information quality is large, we find that voting groups largely coordinate on the SVC equilibrium which is also Pareto Optimal. However, we find that when the asymmetry in information quality is not large and the Pareto Optimal equilibrium is for all to participate, significant numbers of voters with low...... quality information abstain. Furthermore, we find that information asymmetry induces voters with low quality information to coordinate on a non-equilibrium outcome. This suggests that coordination on "letting the experts" decide is a likely voting norm that sometimes validates SVC equilibrium predictions......We examine abstention when voters in standing committees are asymmetrically informed and there are multiple pure strategy equilibria-swing voter's curse (SVC) equilibria where voters with low quality information abstain and equilibria when all participants vote their information. When the asymmetry...

  1. Show or tell: testimony is sufficient to induce the curse of knowledge in three- and four-year-olds. (United States)

    Bhandari, Keera; Barth, Hilary


    Because much of what children learn extends beyond their first-hand experience, they are reliant upon the testimony of others to acquire information about aspects of the world they have not experienced directly. Here we asked whether testimony alone would be sufficient to induce cognitive biases in knowledge attribution that have been observed when children acquire information through direct observation. A total of 80 three- and four-year-old children were tested on a "curse of knowledge" task to assess their inability to override their own knowledge when asked to assess the knowledge of a nave other. In the present study, we tested children's ability to override knowledge gained through testimony rather than knowledge gained through visual experience. Testimony alone was sufficient to induce the curse of knowledge in three- and four-year-olds. Knowledge obtained through the testimony of others is apparently subject to some of the same cognitive biases that are present when children learn through observation.

  2. Autobiographical memories in testimonies of WWII Veterans with dementia

    Directory of Open Access Journals (Sweden)

    Tricia Olea Santos


    Full Text Available This study is a continuation of investigations of personal narratives of healthy older adults and those with aphasia. It focuses on autobiographical memories in testimonies of elderly WWII veterans with dementia, with particular emphasis on emotional events that occurred at the time of their memory peak. This study describes how declines in memory affect changes in language in narratives of memorable experiences at the time in old age when life review is typically experienced. Ten WWII veterans with dementia were selected from a larger study of healthy elderly veterans. Participants were between the ages of 86-91 years old, with the majority obtaining higher education. Based on the Arizona Battery for Communication Disorders of Dementia, participants demonstrated dementia of mild-to-moderate severity. Semi-structured interviews were conducted to elicit memorable war experiences. Modifications to the interview were made, such as the use of photos to set the topic and occasional closed-ended questions to facilitate responses. Information was recorded and analyzed in terms of the amount and specificity of linguistic information, overall coherence of narratives, and the evaluations of memorable war experiences. The participants were not able to produce complete narratives; they instead relayed short episodes of their war experiences. Difficulties with semantic and episodic memory were reflected in the reduced length of their stories. Anomia was inherent in these episodes, as evidenced by the absence of specific names, dates and places. Lack of specificity was exhibited in reduced details and the use of nonspecific referents, such as “thing,” “stuff,” “there.” Participants produced coherent short story episodes. Coherence in episodic structure was maintained by the ability to relate events in a temporal sequence. Repetition was a strategy that served essential functions of emphasizing a point and/or clarifying breakdowns in communication


    Cooper, E. G.


    The Automation Technology Branch of NASA's Langley Research Center is employing increasingly complex degrees of operator/robot cooperation (telerobotics). A good relationship between the operator and computer is essential for smooth performance by a telerobotic system. ESG (Expert Script Generator) is a software package that automatically generates high-level task objective commands from the NASA Intelligent Systems Research Lab's (ISRL's) complex menu-driven language. ESG reduces errors and makes the telerobotics lab accessible to researchers who are not familiar with the comprehensive language developed by ISRL for interacting with the various systems of the ISRL testbed. ESG incorporates expert system technology to capture the typical rules of operation that a skilled operator would use. The result is an operator interface which optimizes the system's capability to perform a task remotely in a hazardous environment, in a timely manner, and without undue stress to the operator, while minimizing the chance for operator errors that may damage equipment. The intricate menu-driven command interface which provides for various control modes of both manipulators and their associated sensors in the TeleRobotic System Simulation (TRSS) has a syntax which is both irregular and verbose. ESG eliminates the following two problems with this command "language": 1) knowing the correct command sequence to accomplish a task, and 2) inputting a known command sequence without typos and other errors. ESG serves as an additional layer of interface, working in conjunction with the menu command processor, not supplanting it. By specifying task-level commands, such as GRASP, CONNECT, etc., ESG will generate the appropriate menu elements to accomplish the task. These elements will be collected in a script file which can then be executed by the ISRL menu command processor. In addition, the operator can extend the list of task-level commands to include customized tasks composed of sub

  6. Service to the South African society through prophetic testimony as a liturgical act

    Directory of Open Access Journals (Sweden)

    Ben J. de Klerk


    Full Text Available It is suggested that a clear prophetic voice of the congregational gathering could change the society to which the congregants belong. The problem is that this prophetic voice seems to have disappeared in many cases. A solution might be found if the point of view is taken that the prophetic voice in the congregational gathering is heard in the liturgical acts or rites. In the science of Liturgy attention must be given to the revitalisation of the gift of prophesy. In this article the prophetic testimony of the Old Testament prophets and of the Prophet, Jesus Christ, were used as sources. Following in the footsteps of Brueggemann, an effort will be made to establish in relevant scripture passages what the attitude and practise of prophetic testimony should be. The possibility of rendering service through prophetic testimony as a liturgical act in the South African society is wide open. Prophetic testimony serves to criticise the dominant perception in order to dismantle it, but is also serves to energise persons and communities by its promise of another time and situation towards which the community of faith could move.

  8. The credibility of recovered memory testimony: exploring the effects of alleged victim and perpetrator gender. (United States)

    Bornstein, B H; Muller, S L


    The purpose was to explore the effects of victim/complainant and perpetrator/defendant gender on the impact of recovered memory testimony in criminal sexual abuse trials. A jury simulation methodology was used. Two hundred forty-six participants read a summary of a sexual abuse trial in which the following three variables were manipulated: the complainant's gender, the defendant's gender, and whether the complainant's memory of the alleged abuse had been "recovered" or remembered all along. Participants reached a verdict and rated the culpability and credibility of the parties. Compared to a case where the memory of the abuse had always been remembered, recovered memory testimony led to lower perceptions of the defendant's culpability and higher perceptions of the defendant's credibility. In addition, the complainant with recovered memory was viewed as less credible and less likely to be telling the truth. These effects of testimony type (i.e., recovered vs. remembered) were qualified by an interaction with complainant and defendant gender, such that testimony type exerted an effect in cases of alleged heterosexual but not homosexual abuse. The results suggest that mock jurors' judgments in sexual abuse cases reflect their stereotypes about sexual abuse and expectations regarding the relative likelihood of repression in various circumstances.

  12. The effects of integrating instrumental and affective arguments in rhetorical and testimonial health messages. (United States)

    Keer, Mario; van den Putte, Bas; de Wit, John; Neijens, Peter


    Recent research highlights the superior influence of affect over cognition in health decision making. The present study examined the independent and combined effects of 2 message characteristics that are thought to tap into the cognition-affect distinction: message format (rhetorical vs. testimonial) and argument type (instrumental vs. affective). In this 2 × 2 experiment, 81 college students were randomly assigned to 1 of 4 health messages discouraging binge drinking. The results indicated that messages containing affective arguments were judged more positively and perceived as more effective than were messages containing instrumental arguments. The results further revealed an interaction effect between message format and argument type. Testimonials were more persuasive when they contained affective arguments than when they contained instrumental arguments. Type of arguments did not influence the efficacy of rhetorical messages. Mediation analyses revealed that instrumental arguments reduce the efficacy of testimonials because they prevent individuals from being transported into the story, and increase psychological reactance. In conclusion, testimonial messages more effectively discourage binge drinking among college students when they contain affective, as opposed to instrumental, arguments.

  17. Expert systems for satellite stationkeeping (United States)

    Mekaru, M. M.; Wright, M. A.

    The feasibility of implementing artificial intelligence on satellites is evaluated, with the aim of using an onboard expert system to perform effective stationkeeping functions without assistance from the ground. The Defense Satellite Communication System (DSCS III) is used as an example. The cost for implementing a satellite stationkeeping expert system is analyzed. A ground-based expert system could reduce the current number of support personnel for the stationkeeping task. Results of analyzing a possible flight system are quite promising. An expert system for satellite stationkeeping seems feasible, appears cost-effective, and offers increased satellite endurance through autonomous operations.

  18. Perceptions of industry responsibility and tobacco control policy by US tobacco company executives in trial testimony. (United States)

    Chaiton, Michael; Ferrence, Roberta; LeGresley, Eric


    Trial testimony from the United States provides a unique opportunity to examine strategies of the American tobacco industry. This paper examines congruence between the arguments for tobacco control policy presented by representatives of the American tobacco industry at trial and the stages of responsibility associated with corporate social responsibility principles in other industries. Trial testimony collected and coded by the Deposition and Trial Testimony Archive (DATTA). All available testimony was gathered from representative senior staff from major tobacco companies: Brown & Williamson, Philip Morris, RJ Reynolds, and Liggett. Transcripts from each witness selected were collected and imported in text format into WinMax, a qualitative data program. The documents were searched for terms relating to tobacco control policies, and relevant terms were extracted. A hand search of the documents was also conducted by reading through the testimony. Inferred responsibility for various tobacco control policies (health information, second-hand smoking, youth smoking) was coded. The level of responsibility for tobacco control policy varied according to the maturity of the issue. For emerging issues, US tobacco company representatives expressed defensiveness while, for more mature issues, such as youth smoking, they showed increased willingness to deal with the issue. This response to social issues is consistent with corporate social responsibility strategies in other industries. While other industries use corporate social responsibility programmes to address social issues to protect their core business product, the fundamental social issue with tobacco is the product itself. As such, the corporate nature of tobacco companies is a structural obstacle to reducing harm caused by tobacco use.

The project will result in a software system that allows its user to build specific monitoring type expert systems which monitor various equipments used for propulsion systems or ground testing facilities and accrues system performance information in a dynamic knowledge base.

  20. War in Colombia testimonial literature: between memory, culture, violence and literature

    Directory of Open Access Journals (Sweden)

    Jorge Eduardo Suárez Gómez


    Full Text Available Colombia may be characterized as a society ruled over by “a routinization of war and oblivion”. When memories about violent events succeed in articulate themselves and transcend the private space, they are not necessarily incorporated to national memory through “memory policies” in transitional processes. These memories are “deposited” rather than discussed. Testimonial literature is one of those “deposits”. There are times when certain topics, witnesses, authors and narrative treatments attain an unexpected relevance. Such a relevance follows national factors, like the dynamics of conflict and society in Colombia and abroad, such as a “turn to past”. When making a survey across the development of the testimonial genre from mid-20th century Violence up to our times, the gravitation of several cultures of memory is made evident in a society where oblivion appears to prevail.

  2. Expert opinion vs. empirical evidence (United States)

    Herman, Rod A; Raybould, Alan


    Expert opinion is often sought by government regulatory agencies when there is insufficient empirical evidence to judge the safety implications of a course of action. However, it can be reckless to continue following expert opinion when a preponderance of evidence is amassed that conflicts with this opinion. Factual evidence should always trump opinion in prioritizing the information that is used to guide regulatory policy. Evidence-based medicine has seen a dramatic upturn in recent years spurred by examples where evidence indicated that certain treatments recommended by expert opinions increased death rates. We suggest that scientific evidence should also take priority over expert opinion in the regulation of genetically modified crops (GM). Examples of regulatory data requirements that are not justified based on the mass of evidence are described, and it is suggested that expertise in risk assessment should guide evidence-based regulation of GM crops.

    As a genre, testimonios or testimonial narratives are not just transgressive of canonical literary aesthetics; they also serve as a tool for otherwise marginalized groups to expose, denounce, and negotiate their experiences of abjection and subordination. These narratives may constitute a counter-hegemonic project, if not an oppositional response, at least, to structures and relations sustained (often brutally) by the apparati of state and capital. In this exploratory paper, I read the letter...

  5. Listening to the patient's self-reported testimony: the authentic hermeneutical witness to the compassionate nurse? (United States)

    Bradshaw, Ann


    This paper considers whether the patient's self-reported testimony of nursing care provides an authentic basis for nursing knowledge. An international nursing and philosophical literature gives international relevance. United Kingdom reports detail patients' complaints about nursing care. Many are personal self-reported testimonies published in the media, but discounted by the nursing profession. Discussion paper. Data sources 1873-2012 include policy documents, nursing studies involving grounded theory, phenomenology and narrative inquiry, nursing textbooks 1882-1971 and the interpretive paradigms of Glaser and Strauss, Heidegger, Ricoeur and Gadamer. Nursing researchers use qualitative methodologies to understand the patient's experience of nursing. Three exemplars reveal epistemological and ontological problems. Epistemologically, researchers are controlling data, their selection and interpretation. Ontologically, the researcher's present horizon dominates because no consideration is given to the historical horizon and context where the tradition of nursing developed and defined the nurse. Arguably, patients' expectations of compassionate nurses bear witness to this past horizon. Patients' self-reported testimonies should be taken seriously as an evidence base for understanding and improving nursing care. Nursing researchers using qualitative methods should be transparent about their pre-judgements. Connections with the past horizon of nursing history should be made to cast light on the present horizon. Patients' self-reported testimonies are more congruent with methods of narrative inquiry than data solicited and filtered by the interviewer's undeclared pre-judgement. They bear witness to the horizon of the past and the meaning and purpose of nursing, its values and ethos. © 2013 John Wiley & Sons Ltd.

    How much knowledge should leaders have of their organization's core business? This is an important question but not one that has been addressed in the management literature.

It suggests that organizations perform more effectively when led by individuals who have a deep understanding of the core business of their organization. Being a capable general manager is not sufficient. Expert...

  8. Conversion and the Real: The (Im)Possibility of Testimonial Representation. (United States)

    Sremac, Srdjan

    Although the spiritual vibration of conversion can be felt (by the curious outsider) through what conversion performers say in their testimonial discourse, what transforms the convert 'on stage' into a 'new being' and what is 'the real' (le réel) in conversion performance remain unclear. An important question in this connection is, What is 'real' in a conversion representation, both with respect to the convert's interaction with the audience and to the construction of social reality? Following Lacan's tripartite register of the imaginary, the symbolic, and the real, in this essay I argue that through testimonial discourse converts construct social reality as an answer to the impossibility of 'the real' in their performative discursive practice. In the first part, I question the constructed nature of testimonial representations-as well as some academic knowledge production that has governed conversion research in the last few decades-and how these representations encourage 'outsiders' to read the narrative repertoire as a negation or mirroring 'the real' of the conversion experience. In the second part, I apply Roland Barthes' analytic reflections on photography to conversion research, especially the notions of the studium (the common ground of cultural meanings) and the punctum (a personal experience that inspires private meaning). This brings me to a number of theorists (mostly never used in the field of religious conversion)-Jacques Lacan, Roland Barthes, and Slavoj Žižek-who are important to the perspective that is developed in this essay.

    CERN Document Server

    Gigerenzer, Gerd


    In today's complex world, we have come to rely increasingly on those who have expertise in specific areas and can bring their knowledge to bear on crucial social, political and scientific questions. Taking the viewpoint that experts are consulted when there is something important at stake for an individual, a group, or society at large, Experts in Science and Society explores expertise as a relational concept. How do experts balance their commitment to science with that to society? How does a society actually determine that a person has expertise? What personal traits are valued in an expert? From where does the expert derive authority? What makes new forms of expertise emerge? These and related questions are addressed from a wide range of areas in order to be inclusive, as well as to demonstrate similarities across areas. Likewise, in order to be culturally comparative, this volume includes examples and discussions of experts in different countries and even in different time periods. The topics include the r...

  11. Expert system application education project (United States)

    Gonzelez, Avelino J.; Ragusa, James M.


    Artificial intelligence (AI) technology, and in particular expert systems, has shown potential applicability in many areas of operation at the Kennedy Space Center (KSC). In an era of limited resources, the early identification of good expert system applications, and their segregation from inappropriate ones can result in a more efficient use of available NASA resources. On the other hand, the education of students in a highly technical area such as AI requires an extensive hands-on effort. The nature of expert systems is such that proper sample applications for the educational process are difficult to find. A pilot project between NASA-KSC and the University of Central Florida which was designed to simultaneously address the needs of both institutions at a minimum cost. This project, referred to as Expert Systems Prototype Training Project (ESPTP), provided NASA with relatively inexpensive development of initial prototype versions of certain applications. University students likewise benefit by having expertise on a non-trivial problem accessible to them at no cost. Such expertise is indispensible in a hands-on training approach to developing expert systems.

  3. Do forensic practitioners distinguish between testifying and consulting experts? A pilot study. (United States)

    Gutheil, Thomas Gordon; Commons, Michael Lamport; Drogin, Eric Y; Hauser, Mark J; Miller, Patrice Marie; Richardson, Andrew Michael


    Forensic mental health professionals (n=44) reviewed a series of statements that an attorney might make to a consulting or testifying expert. Each statement was rated for its degree of appropriateness to either the consulting or the testifying role. In light of increasing attention paid to this topic in the forensic practice literature, as well as long-standing distinctions recognized by the legal profession, it was originally hypothesized that participants would differentiate clearly between these roles; however, results of this pilot study indicate that forensic practitioners do not possess a consistent sense of which activities rest most comfortably within testimonial as opposed to consulting duties.

  9. Making a team of experts into an expert team. (United States)

    Charney, Carol


    Health care has traditionally been delivered primarily by experts working individually in a decentralized system lacking cohesive organization among professional disciplines. Only recently have the advantages of teamwork training been acknowledged in health care. This article explores the history, benefits, and recommendations for team training in neonatal care. TeamSTEPPS (Rockville, MD) and the revised Neonatal Resuscitation Program are cited as promising models for improved neonatal outcomes through professional teamwork.

  10. Analysis of the origin and importance of acetone and isopropanol levels in the blood of the deceased for medico-legal testimony. (United States)

    Borowska-Solonynko, A; Siwińska-Ziółkowska, A; Piotrkowicz, M; Wysmołek, M; Demkow, M


    The aim of the study was to analyze the incidence of acetone and isopropanol in the blood of the deceased, and to assess cases in which the compounds have been detected with a focus on their origin and usefulness for medico-legal testimony. The study material consisted of results of tests detecting ethyl alcohol and reports of autopsies performed at the Department of Forensic Medicine, Medical University of Warsaw, from January 2008 to April 2009 - a total of 2,475 cases. The test group proper (group B) comprised only those cases in which acetone was detected in blood, either with or without isopropanol [n = 202 (8.2%)]. The blood levels of isopropanol varied depending on the cause of death. The need for differentiating the origin of isopropanol in the case of its presence in the blood of the deceased was pointed out. The results of the present study show that the differentiation should be based on the isopropanol and acetone concentration ratio, as isopropanol concentration alone is not sufficient for preparing expert opinions. Even high concentrations of isopropanol, when accompanied by even higher concentrations of acetone, imply that isopropanol could have been formed as a result of acetone transformations. Isopropanol concentrations exceeding acetone levels strongly point to the exogenous origin of isopropanol, particularly when high levels of ethanol are concurrently detected.

  11. On the importance of considering heterogeneity in witnesses' competence levels when reconstructing crimes from multiple witness testimonies. (United States)

    Waubert de Puiseau, Berenike; Greving, Sven; Aßfalg, André; Musch, Jochen


    Aggregating information across multiple testimonies may improve crime reconstructions. However, different aggregation methods are available, and research on which method is best suited for aggregating multiple observations is lacking. Furthermore, little is known about how variance in the accuracy of individual testimonies impacts the performance of competing aggregation procedures. We investigated the superiority of aggregation-based crime reconstructions involving multiple individual testimonies and whether this superiority varied as a function of the number of witnesses and the degree of heterogeneity in witnesses' ability to accurately report their observations. Moreover, we examined whether heterogeneity in competence levels differentially affected the relative accuracy of two aggregation procedures: a simple majority rule, which ignores individual differences, and the more complex general Condorcet model (Romney et al., Am Anthropol 88(2):313-338, 1986; Batchelder and Romney, Psychometrika 53(1):71-92, 1988), which takes into account differences in competence between individuals. 121 participants viewed a simulated crime and subsequently answered 128 true/false questions about the crime. We experimentally generated groups of witnesses with homogeneous or heterogeneous competences. Both the majority rule and the general Condorcet model provided more accurate reconstructions of the observed crime than individual testimonies. The superiority of aggregated crime reconstructions involving multiple individual testimonies increased with an increasing number of witnesses. Crime reconstructions were most accurate when competences were heterogeneous and aggregation was based on the general Condorcet model. We argue that a formal aggregation should be considered more often when eyewitness testimonies have to be assessed and that the general Condorcet model provides a good framework for such aggregations.

  12. A Rapid and Efficient Method for Evaluation of Suspect Testimony: Palynological Scanning. (United States)

    Wiltshire, Patricia E J; Hawksworth, David L; Edwards, Kevin J


    A rapid method for evaluating suspect testimony is valuable at any stage in an inquiry and can result in a change of direction in an investigation. Rape cases, in particular, can present problems where a defendant renders DNA analysis redundant by claiming that the claimant consented to have sexual relations. Forensic palynology is valuable in confirming or eliminating locations as being crime scenes, thus checking the testimony of both parties. In contrast to some forensic disciplines, forensic palynology can provide critical information without time-consuming full analysis. Two cases are described where the palynological assemblages from comparator samples of pertinent places were compared with those obtained from clothing of claimants and defendants. The results of rapid microscopical scanning of relevant preparations led to early confessions, thus obviating the need for costly analyses and protracted court proceedings. A third case demonstrates the unbiased nature of this technique where a man, although innocent of any offense, lied about having visited the crime scene for fear of prosecution. This highlights the need for sensitive policing in claims of rape. © 2015 American Academy of Forensic Sciences.

  13. Support Person Presence and Child Victim Testimony: Believe it or Not. (United States)

    McAuliff, Bradley D; Lapin, Joshua; Michel, Sandra


    This study examined the effects of support person presence on participants' perceptions of an alleged child sexual abuse victim and defendant. Two hundred jury-eligible community members (n = 100 males) viewed a DVD of an 11-year-old girl's simulated courtroom testimony either with or without a female support person seated next to her. Participants found the child victim to be less accurate and trustworthy, and the defendant to be less guilty and less likely to have sexually abused children, when the support person was present. Participants who viewed the female support person (n = 100) believed that she had probably coached and spent a great deal of time with the child victim before testifying. Female participants perceived the child to be more accurate, and the defendant to be more guilty and likely to have sexually abused children, than male participants. The degree to which the child victim's testimonial behavior violated participants' expectancies mediated the negative relation between support person presence and child victim accuracy and trustworthiness. Support person presence was positively associated with expectancy violation, which in turn was negatively associated with child victim accuracy and trustworthiness. These preliminary findings suggest that seating a support person next to an alleged child victim in court may have the unintended effect of decreasing the child's perceived credibility and, if replicated, suggest that alternative seating arrangements might be necessary.

  14. Testimonies of precognition and encounters with psychiatry in letters to J. B. Priestley. (United States)

    Price, Katy


    Using letters sent to British playwright J. B. Priestley in 1963, this paper explores the intersection between patient-focused history of psychiatry and the history of parapsychology in everyday life. Priestley's study of precognition lay outside the main currents of parapsychology, and his status as a storyteller encouraged confidences about anomalous temporal experience and mental illness. Drawing on virtue epistemology, I explore the regulation of subjectivity operated by Priestley in establishing the credibility of his correspondents in relation to their gender and mental health, and investigate the possibility of testimonial justice for these witnesses. Priestley's ambivalent approach to madness in relation to visions of the future is related to the longer history of prophecy and madness. Letters from the television audience reveal a variety of attitudes towards the compatibility of precognition with modern theories of the mind, show the flexibility of precognition in relation to mental distress, and record a range of responses from medical and therapeutic practitioners. Testimonial justice for those whose experience of precognition intersects with psychiatric care entails a full acknowledgement of the tensions and complicities between these two domains as they are experienced by the witness, and an explicit statement of the hearer's orientation to those domains.

  15. Expert witness and Jungian archetypes. (United States)

    Lallave, Juan Antonio; Gutheil, Thomas Gordon


    Jung's theories of archetype, shadow, and the personal and collective unconscious provide a postmodern framework in which to consider the role of the expert witness in judicial proceedings. Archetypal themes, motifs, and influences help to illuminate the shadow of the judicial system and projections and behaviors among the cast of the court in pursuing justice. This article speaks to archetypal influences and dialectical tensions encountered by the expert witness in this judicial drama. The archetype of Justice is born from the human need for order and relational fairness in a world of chaos. The persona of justice is the promise of truth in the drama. The shadow of justice is untruth, the need to win by any means. The dynamics of the trickster archetype serve and promote injustice. These influences are examined by means of a case example. This approach will deepen understanding of court proceedings and the role of the expert witness in the heroic quest for justice. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Expert System for ASIC Imaging (United States)

    Gupta, Shri N.; Arshak, Khalil I.; McDonnell, Pearse; Boyce, Conor; Duggan, Andrew


    With the developments in the techniques of artificial intelligence over the last few years, development of advisory, scheduling and similar class of problems has become very convenient using tools such as PROLOG. In this paper an expert system has been described which helps lithographers and process engineers in several ways. The methodology used is to model each work station according to its input, output and control parameters, combine these work stations in a logical sequence based on past experience and work out process schedule for a job. In addition, all the requirements vis-a-vis a particular job parameters are converted into decision rules. One example is the exposure time, develop time for a wafer with different feature sizes would be different. This expert system has been written in Turbo Prolog. By building up a large number of rules, one can tune the program to any facility and use it for as diverse applications as advisory help, trouble shooting etc. Leitner (1) has described an advisory expert system that is being used at National Semiconductor. This system is quite different from the one being reported in the present paper. The approach is quite different for one. There is stress on job flow and process for another.

  18. Acquisition of Expert/Non-Expert Vocabulary from Reformulations. (United States)

    Antoine, Edwige; Grabar, Natalia


    Technical medical terms are complicated to be correctly understood by non-experts. Vocabulary, associating technical terms with layman expressions, can help in increasing the readability of technical texts and their understanding. The purpose of our work is to build this kind of vocabulary. We propose to exploit the notion of reformulation following two methods: extraction of abbreviations and of reformulations with specific markers. The segments associated thanks to these methods are aligned with medical terminologies. Our results allow to cover over 9,000 medical terms and show precision of extractions between 0.24 and 0.98. The results and analyzed and compared with the existing work.

  9. Expert system validation in prolog (United States)

    Stock, Todd; Stachowitz, Rolf; Chang, Chin-Liang; Combs, Jacqueline


    An overview of the Expert System Validation Assistant (EVA) is being implemented in Prolog at the Lockheed AI Center. Prolog was chosen to facilitate rapid prototyping of the structure and logic checkers and since February 1987, we have implemented code to check for irrelevance, subsumption, duplication, deadends, unreachability, and cycles. The architecture chosen is extremely flexible and expansible, yet concise and complementary with the normal interactive style of Prolog. The foundation of the system is in the connection graph representation. Rules and facts are modeled as nodes in the graph and arcs indicate common patterns between rules. The basic activity of the validation system is then a traversal of the connection graph, searching for various patterns the system recognizes as erroneous. To aid in specifying these patterns, a metalanguage is developed, providing the user with the basic facilities required to reason about the expert system. Using the metalanguage, the user can, for example, give the Prolog inference engine the goal of finding inconsistent conclusions among the rules, and Prolog will search the graph intantiations which can match the definition of inconsistency. Examples of code for some of the checkers are provided and the algorithms explained. Technical highlights include automatic construction of a connection graph, demonstration of the use of metalanguage, the A* algorithm modified to detect all unique cycles, general-purpose stacks in Prolog, and a general-purpose database browser with pattern completion.

  10. The same difference: Jesusa Palancares and Poppie Nongena’s testimonies of oppression

    Directory of Open Access Journals (Sweden)

    M. Wenzel


    Full Text Available Two women's texts from postcolonial countries, Mexico and South Africa, on different continents show surprising correspondences in subject matter and style. Elena Poniatowska’s Hasta no verte Jesús mío (Till I meet you, my Jesus and Elsa Joubert's Die swerfjare van Poppie Nongena (The journey of Poppie Nongena examples of testimonial writing, both address issues of gender and politics in an innovative way. They combine autobiography and biography to render a dramatic account of social injustice despite their disparate backgrounds/cultures and subtle differences in style. In comparison, the texts not only affirm the validity of women’s writing and contribute to its enrichment, but also constitute a valuable contribution towards the formulation of a general feminist aesthetics. In fact, they illustrate conclusively that comparative literature fulfils a vital function in the exploration and interpretation of women's literature from different cultures.

  11. A lesson for the future of our science my testimony on Lord Patrick M S Blackett

    CERN Document Server

    Zichichi, Antonio


    This unique volume contains a tribute to Lord Patrick M S Blackett through the testimony of Professor Antonino Zichichi, who was one of Blackett's pupils in the experiment at the Sphinx Observatory, Europe's highest lab (3580 meters a.s.l.), at Jungfraujoch. The book presents an overview of Blackett's most significant discoveries, such as the so called "vacuum polarization" effect, the first example of "virtual physics" and the "strange particles", that opened a new horizon towards the existence of the subnuclear universe. After discussing the profound implications of Blackett's pioneering contributions to Subnuclear Physics, the book also recalls his deep interest in the promotion of scientific culture. Blackett was firmly convinced that physicists must be engaged directly to let the people outside our labs know what the role of science is in the progress of our civilisation. In particular, according to Blackett and his friend Bertrand Russell, the Manhattan Project was the example of how the new frontiers o...

  12. A testimony to Muzil: Hervé Guibert, Foucault, and the medical gaze. (United States)

    Rendell, Joanne


    Testimony to Muzil: Hervé Guibert, Michel Foucault, and the "Medical Gaze" examines the fictional/autobiographical AIDS writings of the French writer Hervé Guibert. Locating Guibert's writings alongside the work of his friend Michel Foucault, the article explores how they echo Foucault's evolving notions of the "medical gaze." The article also explores how Guilbert's narrators and Guibert himself (as writer) resist and challenge the medical gaze; a gaze which particularly in the era of AIDS has subjected, objectified, and even sometimes punished the body of the gay man. It is argued that these resistances to the gaze offer a literary extension to Foucault's later work on power and resistance strategies.

  13. Effect evaluation of a road safety education program based on victim testimonials in high schools in Belgium. (United States)

    Cuenen, Ariane; Brijs, Kris; Brijs, Tom; Van Vlierden, Karin; Daniels, Stijn; Wets, Geert


    For several decades policy makers worldwide have experimented with testimonials as a strategy to promote road safety supportive views in a wide variety of target populations such as recidivists and students. In its basic format, a (relative of) a victim or an offender brings a personal testimonial of what it is to experience a traffic accident. The underlying idea is that such a testimonial will emotionally affect participants, thereby stimulating them to cognitively reflect upon their own behavior and responsibility as a road user. Unfortunately, empirical literature on the effectiveness of this strategy is rather scarce and inconsistent. This study investigated the effect of a large-scale program with victim testimonials for high schools in Belgium on five socio-cognitive and behavioral variables drawn from the Theory of Planned Behavior (i.e., attitude, subjective norm, perceived behavioral control, behavioral intention and behavior). Moreover, this study investigated program effects on participants' cognitive and emotional estate and whether this influences the program's impact on socio-cognitive and behavioral variables. Our test sample included 1362 students, who were assigned to a baseline - follow-up group and a post-test - follow-up group. We questioned both groups, a first time (just before or after session attendance) on paper, and a second time (two months after session attendance) online. Results indicate the program had, both immediate and two months after attendance, small to medium positive effects on most socio-cognitive and behavioral variables. However, effects depended on participants' demographic profile, their baseline values on the socio-cognitive and behavioral variables, and the degree to which they were cognitively/emotionally affected by the program. We discuss the practical implications of these findings and formulate recommendations for the development of future interventions based on victim testimonials. Copyright © 2016 Elsevier Ltd

    Attilio Agodi


    Full Text Available Some remarks on the problem of knowledge representation and processing, as recognized in connection with the use of computers in the scientific research work, emphasizes the relevance of these problems for the studies on both the theory of languages and the expert system. A consideration of the common traits in the recent history of these studies, with reference to the use of computers on texts in natural language motivates the introduction of set theoretic and algebraic methods, suitable for applications in the analysis and in the automatic treatment of languages, based on the concept of model sets and on relational structures suggested from the connections between syntax and semantics evidenced in some example of sub-languages corresponding to theories of different classes of physical phenomena. Some details of these methods are evidenced, which have already successfully used or whose applications appears suggestive of interesting development.

  19. Methods for combining experts' probability assessments. (United States)

    Jacobs, R A


    This article reviews statistical techniques for combining multiple probability distributions. The framework is that of a decision maker who consults several experts regarding some events. The experts express their opinions in the form of probability distributions. The decision maker must aggregate the experts' distributions into a single distribution that can be used for decision making. Two classes of aggregation methods are reviewed. When using a supra Bayesian procedure, the decision maker treats the expert opinions as data that may be combined with its own prior distribution via Bayes' rule. When using a linear opinion pool, the decision maker forms a linear combination of the expert opinions. The major feature that makes the aggregation of expert opinions difficult is the high correlation or dependence that typically occurs among these opinions. A theme of this paper is the need for training procedures that result in experts with relatively independent opinions or for aggregation methods that implicitly or explicitly model the dependence among the experts. Analyses are presented that show that m dependent experts are worth the same as k independent experts where k < or = m. In some cases, an exact value for k can be given; in other cases, lower and upper bounds can be placed on k.

  20. "It Was the Best Decision of My Life": a thematic content analysis of former medical tourists' patient testimonials. (United States)

    Hohm, Carly; Snyder, Jeremy


    Medical tourism is international travel with the intention of receiving medical care. Medical tourists travel for many reasons, including cost savings, limited domestic access to specific treatments, and interest in accessing unproven interventions. Medical tourism poses new health and safety risks to patients, including dangers associated with travel following surgery, difficulty assessing the quality of care abroad, and complications in continuity of care. Online resources are important to the decision-making of potential medical tourists and the websites of medical tourism facilitation companies (companies that may or may not be affiliated with a clinic abroad and help patients plan their travel) are an important source of online information for these individuals. These websites fail to address the risks associated with medical tourism, which can undermine the informed decision-making of potential medical tourists. Less is known about patient testimonials on these websites, which can be a particularly powerful influence on decision-making. A thematic content analysis was conducted of patient testimonials hosted on the YouTube channels of four medical tourism facilitation companies. Five videos per company were viewed. The content of these videos was analyzed and themes identified and counted for each video. Ten main themes were identified. These themes were then grouped into three main categories: facilitator characteristics (e.g., mentions of the facilitator by name, reference to the price of the treatment or to cost savings); service characteristics (e.g., the quality and availability of the surgeon, the quality and friendliness of the support staff); and referrals (e.g., referrals to other potential medical tourists). These testimonials were found either not to mention risks associated with medical tourism or to claim that these risks can be effectively managed through the use of the facilitation company. The failure fully to address the risks of medical

    Marcinkowski, Jerzy T; Klimberg, Aneta


    The percentage of cases, in which devisors were unable to devise properly was high, what was mostly associated with the frequent drawing up of testaments by chronically ill individuals immediately before death. Grounds for pronouncing the devisor lacking in testamentary capacity were observed in 46.6% of cases, while 39.7% of devisors were found to lack free expression of will. Medical records were available in all the cases, including psychiatric records in 20.5% of cases and neurological records in 20.5%. In the majority of instances, the low quality of medical records hindered formulating expert opinions. The fact that in the majority of cases, the testimonies of witnesses were highly divergent indicated that they were either unable to assess the mental state of the devisor or else were themselves interested in the settlement of the case. Frequently, attending physicians from non-psychiatric wards were unable to answer questions on the mental state of the devisor, what resulted from their focusing on the somatic cause of hospitalization and the fact that their contact with the patient was very limited in time. Problems with certification on the basis of medical records were mainly associated with lacking psychiatric or neurological consults performed at the time the testament was drawn up; in some instances, the entire medical records from that period were missing. For this reason, individuals desiring to prepare a last will should be advised to undergo voluntary psychiatric assessment in this period. Medico-legal opinions in testament cases are difficult and time-consuming, but pleading one's case before the court is even more tedious and difficult.

    In the Expert Meeting Plan, the NorthernSTAR Team proposed to host two Expert Meetings in calendar year 2011. Invitees to the meetings would include experts in the current field of study, other BA team members, and representatives from DOE and NREL. They will invite leading industry experts to present at these meetings. The Expert Meetings will focus on key systems areas that will be required to meet the Building America performance goals and shall be sufficiently narrow in scope that specific conclusions, action items, and delegation of future tasks can be identified and completed. The two expert meeting topics are 'Foundations' and 'Window Retrofit.' The first session is designed as a webinar only and the second will be a live meeting.

  3. Eliciting expert knowledge in conservation science. (United States)

    Martin, Tara G; Burgman, Mark A; Fidler, Fiona; Kuhnert, Petra M; Low-Choy, Samantha; McBride, Marissa; Mengersen, Kerrie


    Expert knowledge is used widely in the science and practice of conservation because of the complexity of problems, relative lack of data, and the imminent nature of many conservation decisions. Expert knowledge is substantive information on a particular topic that is not widely known by others. An expert is someone who holds this knowledge and who is often deferred to in its interpretation. We refer to predictions by experts of what may happen in a particular context as expert judgments. In general, an expert-elicitation approach consists of five steps: deciding how information will be used, determining what to elicit, designing the elicitation process, performing the elicitation, and translating the elicited information into quantitative statements that can be used in a model or directly to make decisions. This last step is known as encoding. Some of the considerations in eliciting expert knowledge include determining how to work with multiple experts and how to combine multiple judgments, minimizing bias in the elicited information, and verifying the accuracy of expert information. We highlight structured elicitation techniques that, if adopted, will improve the accuracy and information content of expert judgment and ensure uncertainty is captured accurately. We suggest four aspects of an expert elicitation exercise be examined to determine its comprehensiveness and effectiveness: study design and context, elicitation design, elicitation method, and elicitation output. Just as the reliability of empirical data depends on the rigor with which it was acquired so too does that of expert knowledge. ©2011 Australian Governmemt Conservation Biology©2011 Society for Conservation Biology.

    This report describes a methodology for identifying, evaluating, and mitigating the loss of key technical skills at nuclear operations facilities. The methodology can be adapted for application within regulatory authorities and research and development organizations, and can be directly applied by international engagement partners of the Department of Energy’s National Nuclear Security Administration (NNSA). The resultant product will be of direct benefit to two types of NNSA missions: (1) domestic human capital development programs tasked to provide focused technical expertise to succeed an aging nuclear operations workforce, and (2) international safeguards programs charged with maintaining operational safeguards for developing/existing nuclear power program in nations where minimal available resources must be used effectively. This report considers succession planning and the critical skills necessary to meet an institution’s goals and mission. Closely tied to succession planning are knowledge management and mentorship. In considering succession planning, critical skill sets are identified and are greatly dependent on the subject matter expert in question. This report also provides examples of critical skills that are job specific.

    Prospective expert system applications in the power industry generally are in one of the following categories:esign, information management, plant operations, and equipment diagnostics. Many power facility expert system efforts are four plant operations. Several of these applications help optimize plant operation and also detect developing problems and suggest remedial action before the occurrence of any serious consequences. Many types of plant processes and equipment can benefit from routine trending and evaluation of operating data by this type of expert system. This paper discusses a variety of special considerations for the development and implementation of expert systems for plant operations, both in general and as exemplified by CYCLEXPRT.

It is Dr. Tylim's position that imagination assists patient and analyst in overcoming the limitations of memory. Imagination is the gateway to truth. In working with survivors, the therapeutic encounter may become a stage where unspeakable experiences attain presence in their absence. The silence or the gaps are then the victim's testimony.

  11. Explosion probability of unexploded ordnance: expert beliefs. (United States)

    MacDonald, Jacqueline Anne; Small, Mitchell J; Morgan, M G


    This article reports on a study to quantify expert beliefs about the explosion probability of unexploded ordnance (UXO). Some 1,976 sites at closed military bases in the United States are contaminated with UXO and are slated for cleanup, at an estimated cost of $15-140 billion. Because no available technology can guarantee 100% removal of UXO, information about explosion probability is needed to assess the residual risks of civilian reuse of closed military bases and to make decisions about how much to invest in cleanup. This study elicited probability distributions for the chance of UXO explosion from 25 experts in explosive ordnance disposal, all of whom have had field experience in UXO identification and deactivation. The study considered six different scenarios: three different types of UXO handled in two different ways (one involving children and the other involving construction workers). We also asked the experts to rank by sensitivity to explosion 20 different kinds of UXO found at a case study site at Fort Ord, California. We found that the experts do not agree about the probability of UXO explosion, with significant differences among experts in their mean estimates of explosion probabilities and in the amount of uncertainty that they express in their estimates. In three of the six scenarios, the divergence was so great that the average of all the expert probability distributions was statistically indistinguishable from a uniform (0, 1) distribution-suggesting that the sum of expert opinion provides no information at all about the explosion risk. The experts' opinions on the relative sensitivity to explosion of the 20 UXO items also diverged. The average correlation between rankings of any pair of experts was 0.41, which, statistically, is barely significant (p= 0.049) at the 95% confidence level. Thus, one expert's rankings provide little predictive information about another's rankings. The lack of consensus among experts suggests that empirical studies

  12. Practical problems in aggregating expert opinions

    Energy Technology Data Exchange (ETDEWEB)

    Booker, J.M.; Picard, R.R.; Meyer, M.A.


    Expert opinion is data given by a qualified person in response to a technical question. In these analyses, expert opinion provides information where other data are either sparse or non-existent. Improvements in forecasting result from the advantageous addition of expert opinion to observed data in many areas, such as meteorology and econometrics. More generally, analyses of large, complex systems often involve experts on various components of the system supplying input to a decision process; applications include such wide-ranging areas as nuclear reactor safety, management science, and seismology. For large or complex applications, no single expert may be knowledgeable enough about the entire application. In other problems, decision makers may find it comforting that a consensus or aggregation of opinions is usually better than a single opinion. Many risk and reliability studies require a single estimate for modeling, analysis, reporting, and decision making purposes. For problems with large uncertainties, the strategy of combining as diverse a set of experts as possible hedges against underestimation of that uncertainty. Decision makers are frequently faced with the task of selecting the experts and combining their opinions. However, the aggregation is often the responsibility of an analyst. Whether the decision maker or the analyst does the aggregation, the input for it, such as providing weights for experts or estimating other parameters, is imperfect owing to a lack of omniscience. Aggregation methods for expert opinions have existed for over thirty years; yet many of the difficulties with their use remain unresolved. The bulk of these problem areas are summarized in the sections that follow: sensitivities of results to assumptions, weights for experts, correlation of experts, and handling uncertainties. The purpose of this paper is to discuss the sources of these problems and describe their effects on aggregation.

  13. Kontra-Diskurso: Testimonial Narratives of Filipino Workers in a Foreign Company

    Directory of Open Access Journals (Sweden)

    Noel Christian A. Moratilla


    Full Text Available As a genre, testimonios or testimonial narratives are not just transgressive of canonical literary aesthetics; they also serve as a tool for otherwise marginalized groups to expose, denounce, and negotiate their experiences of abjection and subordination. These narratives may constitute a counter-hegemonic project, if not an oppositional response, at least, to structures and relations sustained (often brutally by the apparati of state and capital. In this exploratory paper, I read the letters of abused workers as counternarratives that rub against mainstream discourse. In particular, I am using as primary materials the letters written by the Filipino workers of a foreign company which has been recognized and endorsed by state officials for its “contribution” to investment and job generation. Occluded, however, are the stories of abuse, exploitation, and repression among the workers, some of whom have met violent deaths in the workplace. These “littlestories” become counternarratives vis-à-vis the positive, celebratory depiction of the company in official discourse, which bleaches the company of allegations concerning its anti-labor practices. The discussion revolves around how the letters as testimonios and as counternarratives exemplifydiscourses of resistance and solidarity, foregrounding the workers’ denunciation of the abuses committed by and within the company, while also highlighting the workers’ collective responses to these abuses.

    Full Text Available The allegation by a child victim of sexual abuse is, in many cases, the most important evidence of wrongdoing, especially in absence of medical or physical evidence or confessions of guilt. The Rorschach inkblot test is a projective personality assessment technique used to evaluate child witnesses. We report a case of three girls allegedly abused by the father, in which the psychometric evaluation with the Rorschach test did not give credibility to the testimony of the children. When interrogating a minor, it is very difficult to distinguish between a true and a lie. Indeed, many different elements can affect the dialogue, such as the child’s age, the events being discussed, interrogation environment, factors linked to the interviewer, etc. Therefore, it is possible errors of evaluation, misunderstandings or confusion happen frequently. The aim of this case report is to highlight that employment of methodologies and criteria recognised by the scientific community could simplify the acquisition and assessment of information from a minor.

  17. Between memory and silence, the late testimony of a deported homosexual

    Marcelo Spitzner


    Full Text Available This article focuses on the biography of Rudolf Brazda, written by Jean-Luc Schwab. This biography narrates the life and, especially, the deportation of Rudolf Bradzda to the concentration camp of Buchenwald, due to his homosexuality. Brazda was the last pink triangle, title given to homosexuals who were deported to Nazi concentration camps, and one of the few who managed to leave his testimony recorded, even though the writing of another. Thus, I seek in theoretical reflections on history, memory and modernity, a way to point out that narratives such as Brazda’s are delayed or difficult to enter in the collective memory and, therefore, narrate them is configured as struggles against oblivion, silencing and it is a reconstitution of the limits of the historical narrative. Through this text, I propose that history is not made of lines but of wrinkles, the temporality must constantly be revised and that the objective image of collective experience that sustained modernity must be shaken and other genealogies of human experience must be build.

  18. latin American literary testimony: historical foreshadowing of gender in the revolutionary discourse of the sixties

    Directory of Open Access Journals (Sweden)

    Victoria García


    Full Text Available The foundation of testimonio in Latin American literary field, initiated at the end of the ‘60, makes part of the institutionalization of the Cuban revolution, process where its projection to the rest of Latin America constitued a central problem. This paper studies political preconditions of testimonio. In particular, it analizes certain aspects of Cuban revolutionary discourse that anticipate features eventually developed by the literary genre, in the ways the relation between literature and politics is represented, and in the subjects of discourse that are proposed as embodiments of such relation. The paper introduces the question of Cuban revolution, as regards the exemplary status it acquired in Latin America during the sixties. Then, it examines the literary positioning represented by testimonio, as the corollary of a reflexive reconsideration operated by some Latin American writers and critics, concerning their historical role. Finally, it considers three representative documents of Cuban revolution and its continental projection: History will absolve me, by Fidel Castro, and Reminiscences of the Cuban revolutionary war and Bolivian diary, by Ernesto Guevara. We show the textual configuration of a revolutionary subject whose legitimity emerges not only from a political experience which testimony enunciates, but also from particular ways of living and representing literature in the context of a revolutionary practice. In the end of the sixties, the continental literary field would reaffirm such features as its discourse legitimating criteria, during the institutionalization of testimonio as its privileged genre.

  19. Sfragís and its metaphorical testimonial presence in 2 Timothy 2:19

    Directory of Open Access Journals (Sweden)

    Carlos Molina


    Full Text Available This article presented a metaphorical testimonial approach in the interpretation of 2 Timothy 2:19 and the use of sealing. As starting point, attention was given to the concept of ‘seal’ through the Old Testament and Ancient Near East. These periods attest the fact that sealing was also utilised in a figurative way as a sign of ownership, property and authenticity. Sfragís in 2 Timothy 2:19 describes the intimate relationship between Christ and his followers through the terms [foreign font omitted (personal and vital relationship that transcends in practice and [foreign font omitted (mainly an exterior knowledge]. These two vocables are in opposition to [foreign font omitted (to apostate from]. The message expressed in 2:19 exemplifies the principles that Christ lived by and he empowered his followers to stand by. Sfragís in 2 Timothy 2:19 is an imitatio Christi response against the [foreign font omitted] of moral standards and entertainment in the ancient Roman world. It includes a rapid contemporary reflection on practical faithfulness for today’s life.

  20. The Song of Disappearance: Memory, History, and Testimony in the Poetry of Antonio Gamoneda

    Directory of Open Access Journals (Sweden)

    Daniel Aguirre-Oteiza


    Full Text Available This essay explores Antonio Gamoneda’s poetry as an Adornian form of testimony. With its enigmatic foregrounding of lies, the book-length poem Descripción de la mentira ‘Description of the Lie’ can be read as a “contradictory testimony” in which the act and memory of witnessing go, as it were, underground—only to resurface, rife with loss, years after Spain’s transition from dictatorship to democracy. Yet the abstruse character of this poetic writing prevents readers from drawing straightforward political truths about Spanish history from the poem. Losses are inscribed in the text catachrestically, as they truly are: losses. Gamoneda’s poetry has been read amid changing representations of Spain’s recent past, and thus contrastingly seen as an “undecipherable symbolic code” and as “realm of memory.” This reading, which draws on Holocaust studies, allows for a redefinition of the fraught place of modern poetry in the field of Hispanic cultural studies. Examining Descripción de la mentira within the context of the debate about historical memory in Spain sheds light on the theoretical difficulties that dominant aesthetic tendencies encounter in the study of how Spanish poets of recent decades try to establish a dialogue with the reader regarding society, memory, and reality.

  1. (Imposibilidades del sujeto testimonial: aproximaciones interdisciplinarias a la memoria de lo traumático

    Directory of Open Access Journals (Sweden)

    José Cabrera

    Full Text Available Resumen Este artículo tiene como objetivo general promover la reflexión interdisciplinaria, considerando aportes del psicoanálisis y de la historia, acerca de la transmisión de la memoria, en sus dimensiones individuales y colectivas, de acontecimientos traumáticos vinculados a la transgresión de los derechos humanos en el contexto de regímenes autoritarios, desde la perspectiva del sujeto del testimonio. El principal supuesto es que el sujeto testimonial configura discursos que articulan tanto dimensiones representables como irrepresentables de la experiencia mediante la palabra. Así, interesa preguntarse por la posibilidad de que el testimonio presente en su propia organización discursiva esta dimensión que se resiste a la articulación narrativa, cuestión que permite considerar la forma y la función que adquiere lo irrepresentable en los procesos de transmisión de la memoria histórica ligada a los traumas colectivos.

    Wesson, D R; Hink, R H


    Computer programs can assist humans in solving complex problems that cannot be solved by traditional computational techniques using mathematic formulas. These programs, or "expert systems," are commonly used in finance, engineering, and computer design. Although not routinely used in medicine at present, medical expert systems have been developed to assist physicians in solving many kinds of medical problems that traditionally require consultation from a physician specialist. No expert systems are available specifically for drug abuse treatment, but at least one is under development. Where access to a physician specialist in substance abuse is not available for consultation, this expert system will extend specialized substance abuse treatment expertise to nonspecialists. Medical expert systems are a developing technologic tool that can assist physicians in practicing better medicine.

    Directory of Open Access Journals (Sweden)

    Clare eMcCormack


    Full Text Available The aim of this study was to examine the information acquisition strategies of expert and competent non-expert intensive care physicians during two simulated diagnostic scenarios involving respiratory distress in an infant. Specifically, the information acquisition performance of six experts and 12 competent non-experts was examined using an eye tracker during the initial 90 seconds of the assessment of the patient. The results indicated that, in comparison to competent non-experts, experts recorded longer mean fixations, irrespective of the scenario. When the dwell times were examined against specific areas of interest, the results revealed that competent non-experts recorded greater overall dwell times on the nurse, where experts recorded relatively greater dwell times on the head and face of the manikin. In the context of the scenarios, experts recorded differential dwell times, spending relatively more time on the head and face during the seizure scenario than during the coughing scenario. The differences evident between experts and competent non-experts were interpreted as evidence of the relative availability of task-specific cues or heuristics in memory that might direct the process of information acquisition amongst expert physicians. The implications are discussed for the training and assessment of diagnostic skills.

  12. Good expert knowledge, small scope. (United States)

    Mayer, Horst


    During many years of occupational stress research, mostly within the German governmental program for "Humanization of Work Life'', remarkable deficits concerning visual work were seen, the most striking being the lack of cooperation between the different experts. With regard to this article hard arguments and ideas for solutions had to be found. A pilot study in 21 enterprises was realized (1602 employees with different visual work tasks). A test set of screening parameters (visual acuity, refraction, phoria, binocular cooperation and efficiency, accommodation range and color vision) were measured. The glasses and/or contact lenses worn were registered and the visual tasks analyzed. In work at visual display units (VDU) the eye movements were recorded and standardized questionnaires were given (health, stress, visual work situation). Because of the heterogeneity of the sample only simple statistics were applied: in groups of different visual work the complaints, symptoms, hassles and uplifts were clustered (SAS software) and correlated with the results of the visual tests. Later a special project in 8 companies (676 employees) was carried out. The results were published in [14]. Discomfort and asthenopic symptoms could be seen as an interaction of the combination of tasks and working conditions with the clusters of individual functionalisms, frequently originating in postural compromises. Mainly three causes for stress could be identified: 1. demands inadequate with regard to intensity, resolution, amount and/or time structure; 2. prevention of elementary perceptive needs; 3. entire use of partial capacities of the visual organ. Symptoms also were correlated with heteronomy. Other findings: influence of adaptation/accommodation ratio, the distracting role of attractors, especially in multitasking jobs; influence of high luminance differences. Dry eyes were very common, they could be attributed to a high screen position, low light, monotonous tasks and office

  13. Defining 'reasonable medical certainty' in court: What does it mean to medical experts in child abuse cases? (United States)

    Dias, Mark S; Boehmer, Susan; Johnston-Walsh, Lucy; Levi, Benjamin H


    Physicians and others who provide expert testimony in court cases involving alleged child abuse may be instructed to state their conclusions within a 'reasonable medical certainty' (RMC). However, neither judges nor jurors knows what degree of probability constitutes RMC for a given expert, nor whether different experts use different standards to formulate their opinions. We sought to better understand how experts define RMC in the context of court cases. An email survey was sent to members of six list-serves, representing four specialties, whose members testify in child abuse cases. Respondents were asked to define how RMC corresponded to (1) the numerical probability that abuse occurred, (2) the ordinal probability, and (3) how their determinations relate to common legal standards ('preponderance of the evidence', 'clear and convincing', and 'beyond a reasonable doubt'). Participants were also asked how comfortable they were in defining RMC; whether their definition changed according to the charges or type of proceeding; and how they would apply RMC to several hypothetical cases. The 294 list-serve participants who responded included child abuse pediatricians (46%), forensic pathologists (21%), pediatric neurosurgeons (15%), pediatric ophthalmologists (12%), and others (6%). Though 95% of respondents had testified in court, only 45% had received training in the definition of RMC. Only 37% were comfortable defining RMC. Although many responses were highly clustered and paired comparisons showed that 95% of participants' responses were internally consistent, there was variability in respondents' definitions of RMC. There is some variability in how child abuse expert witnesses define and use the term RMC; we provide suggestions about how to more accurately and transparently define RMC to ensure justice in these cases.

  15. Expert judgement models in quantitative risk assessment

    Energy Technology Data Exchange (ETDEWEB)

    Rosqvist, T. [VTT Automation, Helsinki (Finland); Tuominen, R. [VTT Automation, Tampere (Finland)


    Expert judgement is a valuable source of information in risk management. Especially, risk-based decision making relies significantly on quantitative risk assessment, which requires numerical data describing the initiator event frequencies and conditional probabilities in the risk model. This data is seldom found in databases and has to be elicited from qualified experts. In this report, we discuss some modelling approaches to expert judgement in risk modelling. A classical and a Bayesian expert model is presented and applied to real case expert judgement data. The cornerstone in the models is the log-normal distribution, which is argued to be a satisfactory choice for modelling degree-of-belief type probability distributions with respect to the unknown parameters in a risk model. Expert judgements are qualified according to bias, dispersion, and dependency, which are treated differently in the classical and Bayesian approaches. The differences are pointed out and related to the application task. Differences in the results obtained from the different approaches, as applied to real case expert judgement data, are discussed. Also, the role of a degree-of-belief type probability in risk decision making is discussed.

  16. Sherlock Holmes: an expert's view of expertise. (United States)

    André, Didierjean; Fernand, Gobet


    In recent years, there has been an intense research effort to understand the cognitive processes and structures underlying expert behaviour. Work in different fields, including scientific domains, sports, games and mnemonics, has shown that there are vast differences in perceptual abilities between experts and novices, and that these differences may underpin other cognitive differences in learning, memory and problem solving. In this article, we evaluate the progress made in the last years through the eyes of an outstanding, albeit fictional, expert: Sherlock Holmes. We first use the Sherlock Holmes character to illustrate expert processes as described by current research and theories. In particular, the role of perception, as well as the nature and influence of expert knowledge, are all present in the description of Conan Doyle's hero. In the second part of the article, we discuss a number of issues that current research on expertise has barely addressed. These gaps include, for example, several forms of reasoning, the influence of emotions on cognition, and the effect of age on experts' knowledge and cognitive processes. Thus, although nearly 120-year-old, Conan Doyle's books show remarkable illustrations of expert behaviour, including the coverage of themes that have mostly been overlooked by current research.

  17. Expert Mining for Solving Social Harmony Problems (United States)

    Gu, Jifa; Song, Wuqi; Zhu, Zhengxiang; Liu, Yijun

    Social harmony problems are being existed in social system, which is an open giant complex system. For solving such kind of problems the Meta-synthesis system approach proposed by Qian XS et al will be applied. In this approach the data, information, knowledge, model, experience and wisdom should be integrated and synthesized. Data mining, text mining and web mining are good techniques for using data, information and knowledge. Model mining, psychology mining and expert mining are new techniques for mining the idea, opinions, experiences and wisdom. In this paper we will introduce the expert mining, which is based on mining the experiences, knowledge and wisdom directly from experts, managers and leaders.

    A program aimed at the development of an expert system for the reduction of ballistic range data is described. The program applies expert system and artificial intelligence techniques to develop a mathematically complex state-of-the-art spark range data reduction procedure that includes linear theory and six-degree-of-freedom analysis. The scope of the knowledge base includes both spin and statically stable vehicles. The expert system is expected to improve the quality of the data reduction process while reducing the work load on the senior range engineer.

  19. GEST = The Generic Expert System Tool (United States)

    Gilmore, John F.; Ho, David; Howard, Chuck


    The development cycle of an expert system can be decreased if an effective expert system tool (EST) is used. This paper describes the Generic Expert System Tool (GEST) developed by the Artificial Intelligence Branch of the Georgia Tech Research Institute. GEST was developed to be as general purpose as possible while incorporating all of the basic features required of an EST used for real world applications. This paper outlines GEST's basic software architecture and highlights a variety of it's processing elements. A discussion of future enhancement currently being implemented to increase GEST's application domains is also provided.

  20. Psychiatric expert witnesses in the new millennium. (United States)

    Gutheil, Thomas G


    We may anticipate changes in who is the expert in terms of gender, ethnicity, and professional discipline. We anticipate elaboration of training approaches. We foresee emergence of the "forensic tutor" role. We expect expansion of expert roles outside the courtroom. We expect demands for more constraint of expert roles, increased rigor, and empiric support. We expect vast expansion of technologic approaches to assessment and presentation. We expect evolution of ethical issues with preservation of core forensic values but changes in confidentiality, due process, and the nature of assessments. We expect extreme expansion of hard sciences in relation to understanding psychopathology.

  1. Expert - Non-expert differences in visual behaviour during alpine slalom skiing. (United States)

    Decroix, Marjolein; Wazir, Mohd Rozilee Wazir Norjali; Zeuwts, Linus; Deconinck, Frederik F J A; Lenoir, Matthieu; Vansteenkiste, Pieter


    The aim of this study was to investigate visual behaviour of expert and non-expert ski athletes during an alpine slalom. Fourteen non-experts and five expert slalom skiers completed an alpine slalom course in an indoor ski slope while wearing a head-mounted eye tracking device. Experts completed the slalom clearly faster than non-experts, but no significant difference was found in timing and position of the turn initiation. Although both groups already looked at future obstacles approximately 0,5s before passing the upcoming pole, the higher speed of experts implied that they shifted gaze spatially earlier in the bend than non-experts. Furthermore, experts focussed more on the second next pole while non-expert slalom skiers looked more to the snow surface immediately in front of their body. No difference was found in the fixation frequency, average fixation duration, and quiet eye duration between both groups. These results suggest that experts focus on the timing of their actions while non-experts still need to pay attention to the execution of these actions. These results also might suggest that ski trainers should instruct non-experts and experts to focus on the next pole and, shift their gaze to the second next pole shortly before reaching it. Based on the current study it seems unadvisable to instruct slalom skiers to look several poles ahead during the actual slalom. However, future research should test if these results still hold on a real outdoor slope, including multiple vertical gates. Copyright © 2017 Elsevier B.V. All rights reserved.

  2. Positioning the Testimony of Job Ben Solomon, An Enslaved African American Muslim

    Directory of Open Access Journals (Sweden)

    Muna Sulaiman Al-Badaai


    Full Text Available Ayyub Ben Suleiman Diallo, better known as Job ben Solomon was among thousands of African Muslims enslaved in America. Job was a son of a high Priest from Senegal. He was kidnapped by his African enemy and sold as a slave in the New World in 1731. He worked on a tobacco plantation in Maryland. He ran away and was captured and imprisoned. Job’s literacy in Arabic attracted the attention of the philanthropist James Oglethorpe who helped to free him. In 1733, Job sailed to England and later returned to Africa. Upon Job’s request, Thomas Bluett wrote Some Memoirs of the Life of Job the Son of Solomon (1734. Allan Austin claims in his book African Muslims in Antebellum America: Transatlantic Stories and Spiritual Struggles (1997 that Job might be considered as the “father of African American Literature”. Muhammad Al-Ahari (2006 states that this account “is perhaps the earliest biography of any African-Americans”. However, William Andrews (1988 with other scholars consider the year of 1760 the appearance of slave narrative as genre. What is more, African Muslim slave narratives have been excluded from African American anthologies. Florence Marfo (2009 in her article entitled “African Muslims in African American Literature” discusses some possible reasons for this omission which mostly relate to the perceived identity of enslaved African American Muslims and the absence of an anti-slavery goal in their narratives. This paper aims to position Job’s testimony in the light of arguments made by the other scholars.

  3. The Poetry of Holocaust Survivor Testimony: Towards a New Performative Social Science

    Directory of Open Access Journals (Sweden)

    Frances Rapport


    Full Text Available Performative Social Science provides the research scientist with a much needed platform to move beyond traditional approaches to data collection, analysis and the presentation of study findings towards a response to research questions that closely resonates with the raw materials at hand. For the Performative Social Scientist's voice to be heard, new ways must be found to consider how best to represent the social world, relaxing longstanding and rigid qualitative research frameworks in favour of more contemporary and flexible approaches to working that welcome inter-disciplinary practice. By re-defining the theoretical and paradigmatic boundaries of our studies we can then encourage others to consider a range of alternative positions from which to view the world. The paper embraces the potential such a platform offers by presenting one Holocaust survivor's lived experiences of these extraordinary events including internment in Auschwitz-Birkenau concentration camp. Through a visual and textual journey that employs photographs and poetic representations derived from one "research conversation" with the survivor, a "photo-textual montage" aims to engender a more empathic response to survivor testimony. The paper also attempts a novel juxtaposition of images and words to present a richer understanding of the researcher's relationship with the survivor, the research process and research outputs. In effect, the paper maps aspects of the research process in "coming to know" the data in chronological, temporal and spatial frames whilst emphasising the importance of presentation style, format and layout. This paper makes visible what is often invisible in more traditional approaches—the researchers own personal journey and the insights that this affords. URN: urn:nbn:de:0114-fqs0802285

  8. Key attributes of expert NRL referees. (United States)

    Morris, Gavin; O'Connor, Donna


    Experiential knowledge of elite National Rugby League (NRL) referees was investigated to determine the key attributes contributing to expert officiating performance. Fourteen current first-grade NRL referees were asked to identify the key attributes they believed contributed to their expert refereeing performance. The modified Delphi method involved a 3-round process of an initial semi-structured interview followed by 2 questionnaires to reach consensus of opinion. The data revealed 25 attributes that were rated as most important that underpin expert NRL refereeing performance. Results illustrate the significance of the cognitive category, with the top 6 ranked attributes all cognitive skills. Of these, the referees ranked decision-making accuracy as the most important attribute, followed by reading the game, communication, game understanding, game management and knowledge of the rules. Player rapport, positioning and teamwork were the top ranked game skill attributes underpinning performance excellence. Expert referees also highlighted a number of psychological attributes (e.g., concentration, composure and mental toughness) that were significant to performance. There were only 2 physiological attributes (fitness, aerobic endurance) that were identified as significant to elite officiating performance. In summary, expert consensus was attained which successfully provided a hierarchy of the most significant attributes of expert NRL refereeing performance.

  9. "My Invisalign experience": content, metrics and comment sentiment analysis of the most popular patient testimonials on YouTube. (United States)

    Livas, Christos; Delli, Konstantina; Pandis, Nikolaos


    The aim of the study was to investigate the popularity, content of Invisalign patient testimonials on YouTube, as well as the sentiment of the related comments. Using the term "Invisalign experience," the top 100 results on YouTube by view count were screened for English spoken patient videos that attracted comments. Video information (time since video upload, sponsorship), engagement metrics (comments, likes, dislikes, subscriptions), and views were collected. Videos were rated for information completeness (ICS), and comments were classified by origin and content. The emotional loading of the comments was measured using automated sentiment analysis. The 40 reviewed testimonials scored an average ICS of 3.78 (SD 0.97). ICS, time since upload, and video duration did not appear to significantly influence the number of views, subscriptions, likes, dislikes, and comments. There was a statistically significant difference (P = 0.03) between mean positive (2.01, SD 0.95) and negative sentiment scores (- 1.90, SD 1.14). Commenter's status and overall comment on video were significantly associated with positive sentiment scores. There was a significant association between sponsorship, commenter's status, overall comment on video, focus of concern, perceived Invisalign's disadvantages, and increased negative sentiment scores. Engagement of audience and views of the most popular Invisalign patient testimonials were not significantly influenced by completeness of information, video duration, and lifespan. The sentiment of viewers' comments about Invisalign treatment was significantly more positive and was significantly associated with their status, content, and sponsorship of videos. Orthodontic trends on YouTube need to be cautiously monitored for planning interventions that improve patients' knowledge about orthodontics.

  10. Optimizing the Presentation of Mental Health Information in Social Media: The Effects of Health Testimonials and Platform on Source Perceptions, Message Processing, and Health Outcomes. (United States)

    Quintero Johnson, Jessie M; Yilmaz, Gamze; Najarian, Kristy


    Using social media for the purpose of disseminating mental health information is a critical area of scientific inquiry for health communication professionals. The purpose of this study was to investigate whether the presence of a first-person testimonial in educational mental health information placed in Facebook and Twitter messages influenced college students' (N = 257) source perceptions, information processing, cognitive elaboration, health information recall, beliefs, and behavioral intentions. Results show that exposure to social media messages that featured mental health information embedded with a testimonial predicted less source homophily and more critical thoughts about the social media source, less systematic message processing, and less cognitive elaboration. Health information recall was significantly impacted by both the social media platform and message content such that participants in the testimonial condition on Facebook were more likely to recall the health facts in those messages whereas participants who viewed the testimonial in Twitter were less likely to recall the facts in those tweets. Compared to those who read Facebook messages, participants who read Twitter messages reported higher levels of systematic message processing. These findings suggest that the integration of health testimonials into social media messages might inadvertently provoke psychological resistance to mental health information, thereby reducing the persuasive impact of those messages.

  11. Learning from Expert Elicitation in Climate Change (United States)

    Morgan, M. G.


    Since the early 1990's the author has been involved in the design and execution of six detailed expert elicitations that, among other things, have obtained subjective judgments from experts that reflect their best judgment in the form of subjective probability density functions, about the value of key climate variables, climate impacts and a technology for mitigation (Morgan and Keith, 1995; Morgan Pitelka and Shevliakova, 2001; Morgan, Adams and Keith, 2006; Zickfeld et al, 2007; Curtright, Morgan and Keith, 2008; Zickfeld, Morgan Keith and Frame, in review). This paper builds on that experience to draw insights about the design and use of expert elicitation in the assessment and analysis of climate change and its impacts. Several trends in responses will be noted. Methodological pitfalls will be discussed. Comparisons will be drawn with the consensus-based methods employed by IPCC, which appear to have produced tighter uncertainty bounds than individual elicitation. The paper will close with thoughts on the possible use of expert elicitation in future IPCC assessments. Support for this work is from the Climate Decision Making Center through a cooperative agreement between the National Science Foundation (SES-0345798) and Carnegie Mellon University. References: M.

  12. War is hazardous for your health: photographs and testimonies about death, wounds, disease and medical care during the Mexican Revolution. (United States)

    Mraz, John


    Revolutionary wars have devastating and far-reaching effects on the health of the populations caught up in them. However, the deaths and injuries produced by weaponry are only part of the story, because diseases resulting from malnutrition and contaminated drinking water account for the majority of medical problems. This essay uses photographs and testimonies of participants to explore health issues during the Mexican Revolution (1910-1920), as well as incorporating secondary literature on this question. Furthermore, photographic images are not presented as simple (indexical) windows onto the world. Rather, the author attempts to identify the imagemakers and provide explanations that help in imagining the reasons behind the making of the photographs.

  13. Evaluating Expert Estimators Based on Elicited Competences

    Directory of Open Access Journals (Sweden)

    Hrvoje Karna


    Full Text Available Utilization of expert effort estimation approach shows promising results when it is applied to software development process. It is based on judgment and decision making process and due to comparative advantages extensively used especially in situations when classic models cannot be accounted for. This becomes even more accentuated in today’s highly dynamical project environment. Confronted with these facts companies are placing ever greater focus on their employees, specifically on their competences. Competences are defined as knowledge, skills and abilities required to perform job assignments. During effort estimation process different underlying expert competences influence the outcome i.e. judgments they express. Special problem here is the elicitation, from an input collection, of those competences that are responsible for accurate estimates. Based on these findings different measures can be taken to enhance estimation process. The approach used in study presented in this paper was targeted at elicitation of expert estimator competences responsible for production of accurate estimates. Based on individual competences scores resulting from performed modeling experts were ranked using weighted scoring method and their performance evaluated. Results confirm that experts with higher scores in competences identified by applied models in general exhibit higher accuracy during estimation process. For the purpose of modeling data mining methods were used, specifically the multilayer perceptron neural network and the classification and regression decision tree algorithms. Among other, applied methods are suitable for the purpose of elicitation as in a sense they mimic the ways human brains operate. Data used in the study was collected from real projects in the company specialized for development of IT solutions in telecom domain. The proposed model, applied methodology for elicitation of expert competences and obtained results give evidence that in

  14. The Evidence of What Cannot Be Heard: Reading Trauma into and Testimony against the Witness Stand at the International Criminal Tribunal for Rwanda

    Directory of Open Access Journals (Sweden)

    Julia Viebach


    Full Text Available This paper explores the silences and the gaps that cut through witness testimonies at the International Criminal Tribunal for Rwanda (ICTR by applying a trauma lens to the narratives that emerge on the witness stand and by contrasting those with a survivor testimony. It compares the recollection of a traumatic experience with the production of legal meaning. To do so, it focuses specifically on a survivor testimony shared with the author at the Rwandan Nyange memorial in 2014 where the crimes in question happened, and the ICTR The Prosecutor vs Athanase Seromba trial that relates to the events at that particular site. This paper shows that the experience of trauma not only challenges the language of law but also blurs the legal narratives and functions of tribunals like the ICTR.

  15. Auditory memory function in expert chess players. (United States)

    Fattahi, Fariba; Geshani, Ahmad; Jafari, Zahra; Jalaie, Shohreh; Salman Mahini, Mona


    Chess is a game that involves many aspects of high level cognition such as memory, attention, focus and problem solving. Long term practice of chess can improve cognition performances and behavioral skills. Auditory memory, as a kind of memory, can be influenced by strengthening processes following long term chess playing like other behavioral skills because of common processing pathways in the brain. The purpose of this study was to evaluate the auditory memory function of expert chess players using the Persian version of dichotic auditory-verbal memory test. The Persian version of dichotic auditory-verbal memory test was performed for 30 expert chess players aged 20-35 years and 30 non chess players who were matched by different conditions; the participants in both groups were randomly selected. The performance of the two groups was compared by independent samples t-test using SPSS version 21. The mean score of dichotic auditory-verbal memory test between the two groups, expert chess players and non-chess players, revealed a significant difference (p≤ 0.001). The difference between the ears scores for expert chess players (p= 0.023) and non-chess players (p= 0.013) was significant. Gender had no effect on the test results. Auditory memory function in expert chess players was significantly better compared to non-chess players. It seems that increased auditory memory function is related to strengthening cognitive performances due to playing chess for a long time.

  16. Optical Design Using an Expert System

    Energy Technology Data Exchange (ETDEWEB)

    Lerner, S A


    We present, as a different perspective on optimization, an expert system for optimization of optical systems that can be used in conjunction with damped least squared methods to find minima for specific design forms. Expert system optimization differs from global optimization in that it preserves the basic structure of the optical system and limits its search for a minima to a relatively small portion of the design space. In general, the high density of local minima obscures the general trend of the merit function in the region of interest for systems with a large number of variables and constraints. Surprisingly, there may be a potential decrease of an order a magnitude in the merit function for a region of solution space. While global optimization is well-suited to identifying design forms of interest, expert system optimization can be used for in-depth optimization of such forms. An expert system based upon such techniques was used to obtain the winning entry for the 2002 IODC lens design problem. The expert system used is discussed along with other design examples.

  17. The death of Loving: maternal identity as moral constraint in a narrative testimonial advocating physician assisted suicide. (United States)

    Kenny, Robert Wade


    This article considers the narrative testimonial as a rhetorical form in the service of public judgment, with particular attention to the witness's credibility and communicative competence. The author argues that a narrator and witness, as a participant-observer of the events recounted, must generate a story that does not compromise her credibility as a moral agent within the text, and that the capacity to do so is largely a function of communicative competence. Carol Loving's recent book concerning her son's physician assisted suicide is critically assessed to illustrate the primary argument. The critique attempts to show that she neither creates a substantial argument for physician assisted suicide, nor does she warrant her role as a spokesperson for the issue because her narrative violates formative features of maternal identity. Loving's narrative also unintentionally reveals motivational clusters that conflict with and compromise the primary argument, thereby subverting the process of persuasive appeal. Whereas mothers are often mediators for their children in health matters ranging from colds, to psychiatric issues, to matters of death and dying, the failure of Carol Loving in this text, as well as its analysis, should be instructive and cautionary to health professionals who rely on maternal discourse in handling patients, as well as audiences who rely on narrative testimonials as content in their deliberation of public issues.

  18. Experts' Views Regarding the Conceptualization of Narcissism. (United States)

    Ackerman, Robert A; Hands, Aaron J; Donnellan, M Brent; Hopwood, Christopher J; Witt, Edward A


    There is debate over the definition of narcissism across social/personality and clinical psychology. The current article aims to quantify the level of disagreement by measuring experts' opinions concerning the attributes most central to narcissism. Accordingly, we developed a comprehensive list of attributes associated with narcissism and had 49 self-identified experts (among them 17 women, 23 psychologists from clinical psychology and 22 from social/personality psychology) rate these characteristics and provide their opinions on several issues related to the conceptualization of narcissism. Experts generally believe that the grandiose features of narcissism are more central than the vulnerable features. However, differences between clinical and social/personality psychologists were evident, especially regarding the relevance of self-esteem. Given the results, we suggest that researchers specify the kind of narcissism being assessed in a given study and consider using assessments of the full range of narcissistic features in future research to provide a more comprehensive perspective on the construct.

  4. [Medico-expert qualification of iatrogenic diseases]. (United States)

    Belikov, E S


    Medical expert qualification of iatrogenic disease is developed on the basis of insurance assessment of events (accident, realized risk, error) and classification of their causes according to the principle of the triad patient-medical professional-environment taking into account medical technology (diagnosis, treatment, rehabilitation, prophylaxis). Medical error is considered as an integral term and include inadequate (erroneous) professional thinking and/or action. Therefore, it is suggested to qualify a medical error either as a fallacy, or negligence, or omission. Medical-technological standards, apart from legitimacy, are necessary for realization of an expert activity.

    Full Text Available Because of the fact that specialty agricultural assistance is not always available when the farmers need it, we identified expert systems as a strong instrument with an extended potential in agriculture. This started to grow in scale recently, including all socially-economic activity fields, having the role of collecting data regarding different aspects from human experts with the purpose of assisting the user in the necessary steps for solving problems, at the performance level of the expert, making his acquired knowledge and experience available. We opted for a general presentation of the expert systems as well as their necessity, because, the solution to develop the agricultural system can come from artificial intelligence by implementing the expert systems in the field of agricultural insurance, promoting existing insurance products, farmers finding options in depending on their necessities and possibilities. The objective of this article consists of collecting data about different aspects about specific areas of interest of agricultural insurance, preparing the database, a conceptual presentation of a pilot version which will become constantly richer depending on the answers received from agricultural producers, with the clearest exposure of knowledgebase possible. We can justify picking this theme with the fact that even while agricultural insurance plays a very important role in agricultural development, the registered result got from them are modest, reason why solutions need to be found in the scope of developing the agricultural sector. The importance of this consists in the proposal of an immediate viable solution to correspond with the current necessities of agricultural producers and in the proposal of an innovative solution, namely the implementation of expert system in agricultural insurance as a way of promoting insurance products. Our research, even though it treats the subject at an conceptual level, it wants to undertake an

  9. Testimonies to the L'Aquila earthquake (2009) and to the L'Aquila process (United States)

    Kalenda, Pavel; Nemec, Vaclav


    Lot of confusions, misinformation, false solidarity, efforts to misuse geoethics and other unethical activities in favour of the top Italian seismologists responsible for a bad and superficial evaluation of the situation 6 days prior to the earthquake - that is a general characteristics for the whole period of 5 years separating us from the horrible morning of April 6, 2009 in L'Aquila with 309 human victims. The first author of this presentation as a seismologist had unusual opportunity to visit the unfortunate city in April 2009. He got all "first-hand" information that a real scientifically based prediction did exist already for some shocks in the area on March 29 and 30, 2009. The author of the prediction Gianpaolo Giuliani was obliged to stop any public information diffused by means of internet. A new prediction was known to him on March 31 - in the day when the "Commission of Great Risks" offered a public assurance that any immediate earthquake can be practically excluded. In reality the members of the commission completely ignored such a prediction declaring it as a false alarm of "somebody" (even without using the name of Giuliani). The observations by Giuliani were of high quality from the scientific point of view. G. Giuliani predicted L'Aquila earthquake in the professional way - for the first time during many years of observations. The anomalies, which preceded L'Aquila earthquake were detected on many places in Europe in the same time. The question is, what locality would be signed as potential focal area, if G. Giuliani would know the other observations in Europe. The deformation (and other) anomalies are observable before almost all of global M8 earthquakes. Earthquakes are preceded by deformation and are predictable. The testimony of the second author is based on many unfortunate personal experiences with representatives of the INGV Rome and their supporters from India and even Australia. In July 2010, prosecutor Fabio Picuti charged the Commission

  1. Being an expert witness in geomorphology (United States)

    Keller, Edward A.


    Gathering your own data and coming to your own conclusion through scientific research and discovery is the most important principle to remember when being an expert witness in geomorphology. You can only be questioned in deposition and trial in your area of expertise. You are qualified as an expert by education, knowledge, and experience. You will have absolutely nothing to fear from cross-examination if you are prepared and confident about your work. Being an expert witness requires good communication skills. When you make a presentation, speak clearly and avoid jargon, especially when addressing a jury. Keep in mind that when you take on a case that may eventually go to court as a lawsuit, the entire process, with appeals and so forth, can take several years. Therefore, being an expert may become a long-term commitment of your time and energy. You may be hired by either side in a dispute, but your job is the same - determine the scientific basis of the case and explain your scientific reasoning to the lawyers, the judge, and the jury. Your work, including pre-trial investigations, often determines what the case will be based on. The use of science in the discovery part of an investigation is demonstrated from a California case involving the Ventura River, where building of a flood control levee restricted flow to a narrower channel, increasing unit stream power as well as potential for bank erosion and landsliding.

  2. Eliciting and using expert knowledge in metrology (United States)

    O'Hagan, Anthony


    The expression of uncertainty has hitherto been seen as an add-on—first an estimate is obtained and then uncertainty in that estimate is evaluated. We argue that quantification of uncertainty should be an intrinsic part of measurement and that the measurement result should be a probability distribution for the measurand. Full quantification of uncertainties in measurement, recognizing and quantifying all sources of uncertainty, is rarely simple. Many potential sources of uncertainty can effectively only be quantified by the application of expert judgement. Scepticism about the validity or reliability of expert judgement has meant that these sources of uncertainty have often been overlooked, ignored or treated in a qualitative, narrative way. But the consequence of this is that reported expressions of uncertainty regularly understate the true degree of uncertainty in measurements. This article first discusses the concept of quantifying uncertainty in measurement, and then considers some of the areas where expert judgement is needed in order to quantify fully the uncertainties in measurement. The remainder of the article is devoted to describing methodology for eliciting expert knowledge.

  4. Enhancing Transparency in Multidisciplinary Expert Communication

    Energy Technology Data Exchange (ETDEWEB)

    Hukki, Kristiina; Pulkkinen, Urho [VTT Industrial Systems (Finland)


    Faced with problems of public acceptance most nuclear waste management organisations now acknowledge the importance of transparency in their pursuit of solutions for high-level nuclear waste disposal. To make progress the implementing organizations need the trust of other stakeholders in the decision-making process. For such trust these outside stakeholders need knowledge on the grounds for the judgments and decisions made in different scientific and technical disciplines. Transparency is, however, at least as important for the multidisciplinary expert communication itself. As a matter of fact, the transparency of the internal expert interaction processes is a prerequisite for the true transparency of the communication between the implementer and the external stakeholder groups. The introduced conceptual framework has been developed for the identification of the requirements of safety-informed communication in multidisciplinary expert work in nuclear waste management. The framework offers a common thinking model and common concepts which can be utilized in the development of the communication practices. The basis of the framework is on the possibility to understand the safety-critical significance of one's work. The transparency of communication is, for its part, based on making explicit the relevant knowledge necessary for gaining the understanding. This supplementary knowledge, which is related to the substance issues but is not scientific-technical by nature, enhances the experts' awareness of the context of their own contribution and of the background of the other experts' contributions. The common conceptualization and modelling of the knowledge-related dependencies between the tasks make it possible to realize the significance of the supplementary knowledge for transparent communication in actual situations. They also facilitate the recognition of the need for different types of supplementary knowledge in the interfaces between the tasks. By

  5. REXS : A financial risk diagnostic expert system

    ENGLISH ABSTRACT: Artificial intelligence techniques are rapidly emerging as important contributors to more effective management. One of the greatest growth areas probably lies in the use of Expert System methodology for supporting managerial decision processes.
    Existing Decision Support Systems often attempt to apply analytical techniques in combination with traditional data access and retrieval functions. One of the problems usually encountered while developing such decision support systems is the need to transform an unstructured problem environment into a structured analytical model. Using an expert system approach to strategic decision making in such unstructured problem environments may provide significant advantages.
    The financial Risk diagnostic EXpert System (REXS concentrates on Financial Risk Analysis. Based on a Forecasting Model the system will, with the support of several expert system knowledge bases, attempt to evaluate the financial risk of a business and provide guidelines for improvement.

  10. From early detection to rehabilitation in the community: reading beyond the blog testimonies of survivors' quality of life and prostate cancer representation. (United States)

    Zanchetta, Margareth Santos; Cognet, Marguerite; Lam-Kin-Teng, Mary Rachel; Dumitriu, Marie Elisabeth; Renaud, Lise; Rhéaume, Jacques


    Survivors' testimonies can reveal much about men's experiences of prostate cancer and impacts on their quality of life (QOL) during the clinical trajectory of the disease. These survivors' shared thoughts and views were hypothesized to reflect salient features of their lived social representation of prostate cancer. We explored the content of testimonies posted by men to a public blog hosted by a French national prostate cancer patients' association. The study question, "What do French bloggers' testimonies reveal about their lived experiences with prostate cancer, especially regarding their quality of life in community settings, that underpin their social representation of prostate cancer?" guided the exploration and analysis of the textual data. The aims were to better understand men's experiences and predominant thoughts and views, to elucidate patients' behaviours, and to enlighten medical policy and practice. Explore issues of QOL as reported by French prostate cancer survivors in a public blog by: (a) identifying the salient aspects and issues of the experience of living with prostate cancer from the perspective of survivors; and (b) analyzing the content in the posted testimonies regarding perceived and lived impacts of prostate cancer on QOL. A critical ethnographic study guided the selection of textual data from 196 male bloggers' testimonies about prostate cancer posted in the period from 2008 to 2013. Media content analysis method was undertaken on blog testimonies, framed by a multidimensional conceptual framework of QOL. Testimonies focused mainly on medical care and rehabilitation, recovery, health education and self-care, as well as on a global vision of prostate cancer and its impacts on personal views of manhood and masculinity. The language used indicated that political, educative and compassionate discourses were intertwined to create a complex representation of the experience and effects of prostate cancer; this multi-faceted representation can

  11. [Humanities as a means of survival: the testimony of a Siberian prisoner of war in the First World War]. (United States)

    Inić, Suzana; Fatović-Ferenčić, Stella; Kujundžić, Nikola


    This article looks into the autobiography of the Croatian chemist and pharmacognosist Antun Vrgoč (1881-1949) entitled My Memories of the World War 1914-1920 and published in Zagreb in 1937. The author was captured in October 1914 and deported to Siberia, where he remained prisoner of war until 1920. Since there are few memoirs describing the life of Siberian prisoners during the First World War, this work is a precious testimony about the attitude towards the prisoners of war, human relations, and the survival of an AustroHungarian army officer. The book shows a striking lack of civilian or military hostility towards the prisoners and the respect of the Geneva Convention. Antun Vrgoč adopted the culture, customs and language of his formal enemies, took part in their civilian life, and taught at their university. His cathartic experience of survival includes a clear message about the absurdity of war.

  12. Mobilizing Conflict Testimony: A Lens of Mobility for the Study of Documentary Practices in the Kashmir Conflict

    Directory of Open Access Journals (Sweden)

    Max Kramer


    Full Text Available In this paper I introduce a lens of mobility for the study of documentary film practices and gender in zones of conflict. By drawing on my qualitative research regarding the practice of the independent filmmaker Iffat Fatima, I will argue that a lens of mobility helps to grasp highly mobile media practices both conceptually and methodologically. Through a lens of mobility, my focus lies on the potential of documentary film to open the imaginative boundaries of conflict zones and to politically and emotionally mobilize the testimony offered from everyday life in a highly militarized zone. This specifically requires the tracing of moments of political mobilization beyond cognitive questions of conflicting narratives and representations.

  13. Contribution from anthropological reflexivity to an epistemology of the (coconstruction of historical testimonies. Stories of Argentine feminism during the seventies

    Directory of Open Access Journals (Sweden)

    Catalina Trebisacce


    Full Text Available This article is an exercise in anthropological reflexivity based on the methodological analysis of field recording techniques that took place within the development of my doctoral research, related to the study and production of new memories of the feminist movement in Buenos Aires during the seventies. This reflexive work unveils its meaning by looking into how it was produced and the theoretical space -traversed by the historiographical account- in which it took place. This research thoroughly looks into the mode of production of in-depth interviews and, within it, at the role played by researcher expectations and the strategies of each interviewed woman when producing a narrative about herself. For this purpose, epistemic tools developed by feminist theory, anthropology, and memory studies are taken into account. These tools enable the analysis of the dynamic and relational character of testimony production.

    Energy Technology Data Exchange (ETDEWEB)

    Delbeke, J. [Directorate-General for Climate Action, European Commission, Brussels (Belgium)


    Both Europe and the USA have clearly stated in the 2010 ICAO Assembly that they support global goals to limit global international aviation emissions at or below 2005 levels by 2020. Part of the the conclusion of this testimony is as follows: The EU wants to see a comprehensive and non-discriminatory multilateral agreement in ICAO (International Civil Aviation Organisation) on aviation emissions as soon as possible, and the US, EU and other players now need to work together to develop renewed momentum for substantive talks in ICAO at global level. The European Union and the United States have a key role to play in crafting such an international consensus. Working together also requires respecting each others' rules and regulations.

  15. Expert systems for on line security assessment

    Energy Technology Data Exchange (ETDEWEB)

    Christie, R.D.; Talukdar, S.N.


    This paper argues that automatic security assessment schemes cannot generate information of high quality until their architectures, which are now wholly algorithmic, are changed to hybrids combining algorithms with expert systems. In particular, numerical algorithms should continue to be used for simulating the effects of contingencies, but expert systems should be developed for selecting the contingencies and interpreting the simulation results. These changes will make automatic schemes more closely resemble the manual schemes that are used off line too generate assessment information of high quality. The problems of integrating hybrid software into existing Energy Management Systems (EMSs) are far from trivial. The paper goes on to discuss these problems and suggest a solution, namely the use of a network of workstations tied to existing EMS computers.

  16. The Expert Project Management System (EPMS) (United States)

    Silverman, Barry G.; Diakite, Coty


    Successful project managers (PMs) have been shown to rely on 'intuition,' experience, and analogical reasoning heuristics. For new PMs to be trained and experienced PMs to avoid repeating others' mistakes, it is necessary to make the knowledge and heuristics of successful PMs more widely available. The preparers have evolved a model of PM thought processes over the last decade that is now ready to be implemented as a generic PM aid. This aid consists of a series of 'specialist' expert systems (CRITIC, LIBRARIAN, IDEA MAN, CRAFTSMAN, and WRITER) that communicate with each other via a 'blackboard' architecture. The various specialist expert systems are driven to support PM training and problem solving since any 'answers' they pass to the blackboard are subjected to conflict identification (AGENDA FORMULATOR) and GOAL SETTER inference engines.

    Norcross, Scott; Grieser, William H.


    This paper describes a product called the Intelligent Mission Toolkit (IMT), which was created to meet the changing demands of the spacecraft command and control market. IMT is a command and control system built upon an expert system. Its primary functions are to send commands to the spacecraft and process telemetry data received from the spacecraft. It also controls the ground equipment used to support the system, such as encryption gear, and telemetry front-end equipment. Add-on modules allow IMT to control antennas and antenna interface equipment. The design philosophy for IMT is to utilize available commercial products wherever possible. IMT utilizes Gensym's G2 Real-time Expert System as the core of the system. G2 is responsible for overall system control, spacecraft commanding control, and spacecraft telemetry analysis and display. Other commercial products incorporated into IMT include the SYBASE relational database management system and Loral Test and Integration Systems' System 500 for telemetry front-end processing.


    Rogers, J. L.


    The expert system called EXADS was developed to aid users of the Automated Design Synthesis (ADS) general purpose optimization program. Because of the general purpose nature of ADS, it is difficult for a nonexpert to select the best choice of strategy, optimizer, and one-dimensional search options from the one hundred or so combinations that are available. EXADS aids engineers in determining the best combination based on their knowledge of the problem and the expert knowledge previously stored by experts who developed ADS. EXADS is a customized application of the AESOP artificial intelligence program (the general version of AESOP is available separately from COSMIC. The ADS program is also available from COSMIC.) The expert system consists of two main components. The knowledge base contains about 200 rules and is divided into three categories: constrained, unconstrained, and constrained treated as unconstrained. The EXADS inference engine is rule-based and makes decisions about a particular situation using hypotheses (potential solutions), rules, and answers to questions drawn from the rule base. EXADS is backward-chaining, that is, it works from hypothesis to facts. The rule base was compiled from sources such as literature searches, ADS documentation, and engineer surveys. EXADS will accept answers such as yes, no, maybe, likely, and don't know, or a certainty factor ranging from 0 to 10. When any hypothesis reaches a confidence level of 90% or more, it is deemed as the best choice and displayed to the user. If no hypothesis is confirmed, the user can examine explanations of why the hypotheses failed to reach the 90% level. The IBM PC version of EXADS is written in IQ-LISP for execution under DOS 2.0 or higher with a central memory requirement of approximately 512K of 8 bit bytes. This program was developed in 1986.

  20. Unsaturated Zone Flow Model Expert Elicitation Project

    Energy Technology Data Exchange (ETDEWEB)

    Coppersmith, K. J.


    This report presents results of the Unsaturated Zone Flow Model Expert Elicitation (UZFMEE) project at Yucca Mountain, Nevada. This project was sponsored by the US Department of Energy (DOE) and managed by Geomatrix Consultants, Inc. (Geomatrix), for TRW Environmental Safety Systems, Inc. The objective of this project was to identify and assess the uncertainties associated with certain key components of the unsaturated zone flow system at Yucca Mountain. This assessment reviewed the data inputs, modeling approaches, and results of the unsaturated zone flow model (termed the ''UZ site-scale model'') being developed by Lawrence Berkeley National Laboratory (LBNL) and the US Geological Survey (USGS). In addition to data input and modeling issues, the assessment focused on percolation flux (volumetric flow rate per unit cross-sectional area) at the potential repository horizon. An understanding of unsaturated zone processes is critical to evaluating the performance of the potential high-level nuclear waste repository at Yucca Mountain. A major goal of the project was to capture the uncertainties involved in assessing the unsaturated flow processes, including uncertainty in both the models used to represent physical controls on unsaturated zone flow and the parameter values used in the models. To ensure that the analysis included a wide range of perspectives, multiple individual judgments were elicited from members of an expert panel. The panel members, who were experts from within and outside the Yucca Mountain project, represented a range of experience and expertise. A deliberate process was followed in facilitating interactions among the experts, in training them to express their uncertainties, and in eliciting their interpretations. The resulting assessments and probability distributions, therefore, provide a reasonable aggregate representation of the knowledge and uncertainties about key issues regarding the unsaturated zone at the Yucca

  10. Developing a biomedical expert finding system using medical subject headings. (United States)

    Singh, Harpreet; Singh, Reema; Malhotra, Arjun; Kaur, Manjit


    Efficient identification of subject experts or expert communities is vital for the growth of any organization. Most of the available expert finding systems are based on self-nomination, which can be biased, and are unable to rank experts. Thus, the objective of this work was to develop a robust and unbiased expert finding system which can quantitatively measure expertise. Medical Subject Headings (MeSH) is a controlled vocabulary developed by the National Library of Medicine (NLM) for indexing research publications, articles and books. Using the MeSH terms associated with peer-reviewed articles published from India and indexed in PubMed, we developed a Web-based program which can be used to identify subject experts and subjects associated with an expert. We have extensively tested our system to identify experts from India in various subjects. The system provides a ranked list of experts where known experts rank at the top of the list. The system is general; since it uses information available with the PubMed, it can be implemented for any country. The expert finding system is able to successfully identify subject experts in India. Our system is unique because it allows the quantification of subject expertise, thus enabling the ranking of experts. Our system is based on peer-reviewed information. Use of MeSH terms as subjects has standardized the subject terminology. The system matches requirements of an ideal expert finding system.

  11. Fuzzy Expert System for Heart Attack Diagnosis (United States)

    Hassan, Norlida; Arbaiy, Nureize; Shah, Noor Aziyan Ahmad; Afizah Afif@Afip, Zehan


    Heart attack is one of the serious illnesses and reported as the main killer disease. Early prevention is significant to reduce the risk of having the disease. The prevention efforts can be strengthen through awareness and education about risk factor and healthy lifestyle. Therefore the knowledge dissemination is needed to play role in order to distribute and educate public in health care management and disease prevention. Since the knowledge dissemination in medical is important, there is a need to develop a knowledge based system that can emulate human intelligence to assist decision making process. Thereby, this study utilized hybrid artificial intelligence (AI) techniques to develop a Fuzzy Expert System for Diagnosing Heart Attack Disease (HAD). This system integrates fuzzy logic with expert system, which helps the medical practitioner and people to predict the risk and as well as diagnosing heart attack based on given symptom. The development of HAD is expected not only providing expert knowledge but potentially become one of learning resources to help citizens to develop awareness about heart-healthy lifestyle.

  12. IMBA Expert: internal dosimetry made simple. (United States)

    Birchall, A; Puncher, M; James, A C; Marsh, J W; Jarvis, N S; Peace, M S; Davis, K; King, D J


    In 1997, a collaboration between British Nuclear Fuels plc (BNFL), Westlakes Research Institute and NRPB started, with the aim of producing IMBA (Integrated Modules for Bioassay Analysis), a suite of software modules that implement the new ICRP models for estimation of intakes and doses. This was partly in response to new UK regulations, and partly due to the requirement for a unified approach in estimating intakes and doses from bioassay measurements within the UK. Over the past 5 years, the IMBA modules have been developed further, have gone through extensive quality assurance, and are now used for routine dose assessment by approved dosimetry services throughout the UK. More recently, interest in the IMBA methodology has been shown by the United States Department of Energy (USDOE), and in 2001 an ambitious project to develop a software package (IMBA Expert USDOE Edition) which would meet the requirements of all of the major USDOE sites began. Interest in IMBA Expert is now being expressed in many other countries. The aim of this paper is to outline the origin and evolution of the IMBA modules (the past); to describe the full capabilities of the current IMBA Expert system (the present) and to indicate possible future directions in terms of capabilities and availability (the future).

  13. Quantitative knowledge acquisition for expert systems (United States)

    Belkin, Brenda L.; Stengel, Robert F.


    A common problem in the design of expert systems is the definition of rules from data obtained in system operation or simulation. While it is relatively easy to collect data and to log the comments of human operators engaged in experiments, generalizing such information to a set of rules has not previously been a direct task. A statistical method is presented for generating rule bases from numerical data, motivated by an example based on aircraft navigation with multiple sensors. The specific objective is to design an expert system that selects a satisfactory suite of measurements from a dissimilar, redundant set, given an arbitrary navigation geometry and possible sensor failures. The systematic development is described of a Navigation Sensor Management (NSM) Expert System from Kalman Filter convariance data. The method invokes two statistical techniques: Analysis of Variance (ANOVA) and the ID3 Algorithm. The ANOVA technique indicates whether variations of problem parameters give statistically different covariance results, and the ID3 algorithms identifies the relationships between the problem parameters using probabilistic knowledge extracted from a simulation example set. Both are detailed.

  14. Pollution of Illinois and Mississippi Rivers by Chicago sewage, a digest of the testimony taken in the case of the State of Missouri v. the State of Illinois and the Sanitary District of Chicago (United States)

    Leighton, Marshall O.


    The testimony taken in the suit of the State of Missouri against the State of Illinois and the sanitary district of Chicago comprises the best symposium on river pollution, its biological and chemical aspects, and its general and special sanitary significance that has ever been assembled. The contentions of both parties to the suit' are supported by the most eminently qualified men in the United States. The evidence presented and the discussions recorded are therefore of unique importance. The final record of testimony occupies 8,000 printed pages, much of which is irrelevant. This digest of testimony is the result of an attempt to recover the valuable material and present it in concise form. A consistent endeavor has been made by the reviewer to eliminate all personal opinions with reference to the issue and to make an impartial presentation of so much of the testimony as in his opinion appears to be relevant and of scientific importance. It will be well to remember in this connection that any digest of so large a volume of testimony must be the result of a final exercise of personal opinion by the reviewer as to those parts which may best be excluded. Naturally opinions will differ on this point; therefore it will be strange if many of those familiar with the case do not find that certain portions of testimony which they consider most important are passed over in this digest without reference. Controversies between counsel, objections to the admission of testimony, legal technicalities and quibbles, badgering cross-examination, and in general all the testimony introduced for purposes of mere corroboration have been disregarded. The object has been to present a faithful statement of the scientific phases of the testimony to the exclusion, if need be, of the legal aspect of the case. 

  15. Identifying a Computer Forensics Expert: A Study to Measure the Characteristics of Forensic Computer Examiners

    Directory of Open Access Journals (Sweden)

    Gregory H. Carlton


    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 The usage of digital evidence from electronic devices has been rapidly expanding within litigation, and along with this increased usage, the reliance upon forensic computer examiners to acquire, analyze, and report upon this evidence is also rapidly growing. This growing demand for forensic computer examiners raises questions concerning the selection of individuals qualified to perform this work. While courts have mechanisms for qualifying witnesses that provide testimony based on scientific data, such as digital data, the qualifying criteria covers a wide variety of characteristics including, education, experience, training, professional certifications, or other special skills. In this study, we compare task performance responses from forensic computer examiners with an expert review panel and measure the relationship with the characteristics of the examiners to their quality responses. The results of this analysis provide insight into identifying forensic computer examiners that provide high-quality responses. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  16. Expert system application for prioritizing preventive actions for shift work: shift expert. (United States)

    Esen, Hatice; Hatipoğlu, Tuğçen; Cihan, Ahmet; Fiğlali, Nilgün


    Shift patterns, work hours, work arrangements and worker motivations have increasingly become key factors for job performance. The main objective of this article is to design an expert system that identifies the negative effects of shift work and prioritizes mitigation efforts according to their importance in preventing these negative effects. The proposed expert system will be referred to as the shift expert. A thorough literature review is conducted to determine the effects of shift work on workers. Our work indicates that shift work is linked to demographic variables, sleepiness and fatigue, health and well-being, and social and domestic conditions. These parameters constitute the sections of a questionnaire designed to focus on 26 important issues related to shift work. The shift expert is then constructed to provide prevention advice at the individual and organizational levels, and it prioritizes this advice using a fuzzy analytic hierarchy process model, which considers comparison matrices provided by users during the prioritization process. An empirical study of 61 workers working on three rotating shifts is performed. After administering the questionnaires, the collected data are analyzed statistically, and then the shift expert produces individual and organizational recommendations for these workers.

    Energy Technology Data Exchange (ETDEWEB)


    The work performed to meet the requirement of this task is a continuing effort, evolving toward a general-purpose reasoning tool. The idea here is to build a more-powerful general expert system than the previous one. Towards that, this new Bayesian inference engine is based on the work done by Pearl and Kim. The advantages of this new inference engine over the previous one are that the representation of the knowledge is more compact and the inferencing is suitable for parallel processing. The inference engine is written in Franz lisp on VAX machine. All the code and a typescript of how to load and use the system is attached.

  20. Toward an expert project management system (United States)

    Silverman, Barry G.; Murray, Arthur; Diakite, Coty; Feggos, Kostas


    The purpose of the research effort is to prescribe a generic reusable shell that any project office can install and customize for the purposes of advising, guiding, and supporting project managers in that office. The prescribed shell is intended to provide both: a component that generates prescriptive guidance for project planning and monitoring activities, and an analogy (intuition) component that generates descriptive insights of previous experience of successful project managers. The latter component is especially significant in that it has the potential to: retrieve insights, not just data, and provide a vehicle for expert PMs to easily transcribe their current experiences in the course of each new project managed.

  2. A Combinatorial Auction among Versatile Experts and Amateurs (United States)

    Ito, Takayuki; Yokoo, Makoto; Matsubara, Shigeo

    Auctions have become an integral part of electronic commerce and a promising field for applying multi-agent technologies. Correctly judging the quality of auctioned goods is often difficult for amateurs, in particular, in Internet auctions. However, experts can correctly judge the quality of goods. In this situation, it is difficult to make experts tell the truth and attain an efficient allocation, since experts have a clear advantage over amateurs and they would not reveal their valuable information without some reward. In our previous work, we have succeeded in developing such auction protocols under the following two cases: (1) the case of a single-unit auction among experts and amateurs, and (2) the case of a combinatorial auction among single-skilled experts and amateurs. In this paper, we focus on versatile experts. Versatile experts have an interest in, and expert knowledge on the qualities of several goods. In the case of versatile experts, there would be several problems, e.g., free riding problems, if we simply extended the previous VCG-style auction protocol. Thus, in this paper, we employ PORF (price-oriented, rationing-free) protocol for designing our new protocol to realize a strategy-proof auction protocol for experts. In the protocol, the dominant strategy for experts is truth-telling. Also, for amateurs, truth-telling is the best response when two or more experts select the dominant strategy. Furthermore, the protocol is false-name-proof.

  9. Comparing the quality of crowdsourced data contributed by expert and non-experts.

    Directory of Open Access Journals (Sweden)

    Linda See

    Full Text Available There is currently a lack of in-situ environmental data for the calibration and validation of remotely sensed products and for the development and verification of models. Crowdsourcing is increasingly being seen as one potentially powerful way of increasing the supply of in-situ data but there are a number of concerns over the subsequent use of the data, in particular over data quality. This paper examined crowdsourced data from the Geo-Wiki crowdsourcing tool for land cover validation to determine whether there were significant differences in quality between the answers provided by experts and non-experts in the domain of remote sensing and therefore the extent to which crowdsourced data describing human impact and land cover can be used in further scientific research. The results showed that there was little difference between experts and non-experts in identifying human impact although results varied by land cover while experts were better than non-experts in identifying the land cover type. This suggests the need to create training materials with more examples in those areas where difficulties in identification were encountered, and to offer some method for contributors to reflect on the information they contribute, perhaps by feeding back the evaluations of their contributed data or by making additional training materials available. Accuracies were also found to be higher when the volunteers were more consistent in their responses at a given location and when they indicated higher confidence, which suggests that these additional pieces of information could be used in the development of robust measures of quality in the future.

  10. Expert Discussion on Taking a Spiritual History. (United States)

    Paal, Piret; Frick, Eckhard; Roser, Traugott; Jobin, Guy


    This article elaborates on the hazards of spiritual history taking. It provides expert insights to consider before entering the field. In summer 2012, a group of spiritual care experts were invited to discuss the complexity of taking spiritual histories in a manner of hermeneutic circle. Thematic analysis was applied to define the emerging themes. The results demonstrate that taking a spiritual history is a complex and challenging task, requiring a number of personal qualities of the interviewer, such as 'being present', 'not only hearing, but listening', 'understanding the message beyond the words uttered', and 'picking up the words to respond'. To 'establish a link of sharing', the interviewer is expected 'to go beyond the ethical stance of neutrality'. The latter may cause several dilemmas, such as 'fear of causing more problems', 'not daring to take it further', and above all, 'being ambivalent about one's role'. Interviewer has to be careful in terms of the 'patient's vulnerability'. To avoid causing harm, it is essential to propose 'a follow-up contract' that allows responding to 'patient's yearning for genuine care'. These findings combined with available literature suggest that the quality of spiritual history taking will remain poor unless the health-care professionals revise the meaning of spirituality and the art of caring on individual level.

  11. WHO Expert Committee on Drug Dependence (United States)


    The WHO Expert Committee on Drug Dependence (ECDD) is responsible for assessing psychoactive substances for possible control under the international drug control conventions. The ECDD reviews the therapeutic usefulness, the liability for abuse and dependence, and the public health and social harm potential of each substance under review. After the ECDD advises the Director-General of WHO as to whether to schedule or to amend the scheduling status of a substance, the Director-General will, as appropriate, communicate the recommendations to the United Nations Secretary-General. The Secretary-General communicates the advice to the Commission on Narcotic Drugs (CND), as appropriate. This report presents the recommendations of the thirty-seventh meeting of the WHO Expert Committee on Drug Dependence. The report summarizes the review of nine substances and the ECDD’s recommendations for the scheduling of seven substances. The report also provides updates on ketamine and cannabis, as requested byresolutions of the Commission on Narcotic Drugs. It contains updates on the work of international bodies concerned with controlled substances, as well as summaries of the follow-up discussions on recommendations made at the previous ECDD meeting, and on the discussions on criteria for assessing new psychoactive substances and on terminology.

  13. An expert system for wind shear avoidance (United States)

    Stengel, Robert F.; Stratton, D. Alexander


    The principal objectives are to develop methods for assessing the likelihood of wind shear encounter (based on real-time information in the cockpit), for deciding what flight path to pursue (e.g., takeoff abort, landing go-around, or normal climbout or glide slope), and for using the aircraft's full potential for combating wind shear. This study requires the definition of both deterministic and statistical techniques for fusing internal and external information, for making go/no-go decisions, and for generating commands to the aircraft's autopilot and flight directors for both automatic and manually controlled flight. The expert system for pilot aiding is based on the results of the FAA Windshear Training Aids Program, a two-volume manual that presents an overview, pilot guide, training program, and substantiating data that provides guidelines for this initial development. The Windshear Safety Advisor expert system currently contains over 140 rules and is coded in the LISP programming language for implementation on a Symbolics 3670 LISP Machine.

  14. Rotating Machinery Predictive Maintenance Through Expert System

    Directory of Open Access Journals (Sweden)

    M. Sarath Kumar


    Full Text Available Modern rotating machines such as turbomachines, either produce or absorb huge amount of power. Some of the common applications are: steam turbine-generator and gas turbine-compressor-generator trains produce power and machines, such as pumps, centrifugal compressors, motors, generators, machine tool spindles, etc., are being used in industrial applications. Condition-based maintenance of rotating machinery is a common practice where the machine's condition is monitored constantly, so that timely maintenance can be done. Since modern machines are complex and the amount of data to be interpreted is huge, we need precise and fast methods in order to arrive at the best recommendations to prevent catastrophic failure and to prolong the life of the equipment. In the present work using vibration characteristics of a rotor-bearing system, the condition of a rotating machinery (electrical rotor is predicted using an off-line expert system. The analysis of the problem is carried out in an Object Oriented Programming (OOP framework using the finite element method. The expert system which is also developed in an OOP paradigm gives the type of the malfunctions, suggestions and recommendations. The system is implemented in C++.

  15. The Expert Patient and Chronic Respiratory Diseases

    Directory of Open Access Journals (Sweden)

    Louis-Philippe Boulet


    Full Text Available The concept of “expert patient” has been developed in the last two decades to define a patient who has a significant knowledge of his/her disease and treatment in addition to self-management skills. However, this concept has evolved over the last years, and these patients are now considered, not only to be more efficient in the management of their own condition and communicating effectively with health professionals, but to also act as educators for other patients and as resources for the last, provide feedback on care delivery, and be involved in the production and implementation of practice guidelines, as well as in the development and conduct of research initiatives. There are some barriers, however, to the integration of this new contributor to the health care team, and specific requirements need to be considered for an individual to be considered as an expert. This new player has, however, a potentially important role to improve current care, particularly in respiratory health.

  16. A diagnostic expert system for digital circuits (United States)

    Backlund, R. W.; Wilson, J. D.


    A scheme is presented for a diagnostic expert system which is capable of troubleshooting a faulty digital circuit or producing a reduced test vector set for a non-faulty digital circuit. It is based on practical fault-finding logic and utilizes artificial intelligence techniques. The program uses expert knowledge comprised of two components: that which is contained within the program in the form of rules and heuristics, and that which is derived from the circuit under test in the form of specific device information. Using both forward and backward tracking algorithms, signal paths comprised of device and gate interconnections are identified from each output pin to the primary input pins which have effect on them. Beginning at the output, the program proceeds to validate each device in each signal path by forward propagating test values through the device to the output, and backward propagating the same values to the primary inputs. All devices in the circuit are monitored for each test applied and their performance is recorded. Device or gate validation occurs when the recorded history shows that a device has been toggled successfully through all necessary states. When run on a circuit which does not contain a fault, the program determines a reduced test vector set for that circuit.

    Rafaella Guimarães Moraes CAMARGO

    Full Text Available ABSTRACT Objective: To identify attributes that promote healthy eating in order to support a study for the Quality Index for School Meal Menus content validity. Methods: This study used the Delphi technique to consult school nutrition experts in Brazil. These experts were selected among the authors of articles published between 2010 and 2015 that were identified by searching the Web of Science database, using the keywords 'school feeding', 'school nutrition program', and 'school food program', as well as the authors of official documents on this topic. The Likert method was used to record respondent perceptions in two analytical dimensions: foods that are part of a healthy menu for school feeding, and composition of an indicator of nutritional quality for school feeding menus. Results: Most respondents (n=27 were affiliated with public institutions (92.59% and had over six years of experience in the area (70.36%. Assertions resulted in consensus according to the analysis criteria. A consensus was established for fresh food, fruits and vegetables, dairy products, beans, meat and eggs, and a schedule compatible with the meal as promoters of healthy eating, and processed foods, sweets, and fat excess as risk attributes. Conclusion: Since a consensus was not reached in the first round, there is a need to broaden the debate on issues related to foods rich in sugar, replacement of meals by sweets, and foods rich in fat.

  18. The Application of Big-Neuron Theory in Expert Systems

    Institute of Scientific and Technical Information of China (English)



    With a new way of knowledge representation and acquirement, inference, and building an expert system based on big-neurons composed of different field expert knowledge presented, the fundamental theory and architecture of expert system based upon big-neuron theory has thus been built. It is unnecessary to organize a large number of production rules when using big-neurons to build an expert system. The facts and rules of an expert system have already been hidden in big-neurons. And also, it is unnecessary to do a great quantity of tree searching when using this method to do logic reasoning. Machine can do self-organizing and self-learning.

[Department of Surgery, Academic Medical Center, University of Amsterdam (Netherlands); Stoker, Jaap [Department of Radiology, Academic Medical Center, University of Amsterdam (Netherlands)


    Objective: To compare accuracy and interobserver agreement between radiologists with limited experience in the evaluation of abdominal MRI (non-experts), and radiologists with longer MR reading experience (experts), in reading MRI in patients with suspected appendicitis. Methods: MR imaging was performed in 223 adult patients with suspected appendicitis and read independently by two members of a team of eight MR-inexperienced radiologists, who were trained with 100 MR examinations previous to this study (non-expert reading). Expert reading was performed by two radiologists with a larger abdominal MR experience (>500 examinations) in consensus. A final diagnosis was assigned after three months based on all available information, except MRI findings. We estimated MRI sensitivity and specificity for appendicitis and for all urgent diagnoses separately. Interobserver agreement was evaluated using kappa statistics. Results: Urgent diagnoses were assigned to 147 of 223 patients; 117 had appendicitis. Sensitivity for appendicitis was 0.89 by MR-non-expert radiologists and 0.97 in MR-expert reading (p = 0.01). Specificity was 0.83 for MR-non-experts versus 0.93 for MR-expert reading (p = 0.002). MR-experts and MR-non-experts agreed on appendicitis in 89% of cases (kappa 0.78). Accuracy in detecting urgent diagnoses was significantly lower in MR-non-experts compared to MR-expert reading: sensitivity 0.84 versus 0.95 (p < 0.001) and specificity 0.71 versus 0.82 (p = 0.03), respectively. Agreement on urgent diagnoses was 83% (kappa 0.63). Conclusion: MR-non-experts have sufficient sensitivity in reading MRI in patients with suspected appendicitis, with good agreement with MR-expert reading, but accuracy of MR-expert reading was higher.

    Television is a powerful medium through which to convey information and messages to the public. The recent proliferation of forensic science and criminal justice information throughout all forms of media, coupled with raised expectations toward forensic evidence, has led some to suspect that a "CSI effect" ( Crime Scene Investigation effect) is taking place. The present study contributes to the literature addressing the CSI effect in two ways. First, it examines whether the CSI effect exists in the Chinese population of Hong Kong. Second, using a mock-jury paradigm, it empirically examines a more integrative perspective of the CSI effect. It was found that, although the amount of media coverage involving forensic evidence does influence participants' perception of legal evidence to some degree, such a perception does not affect participants' legal decision making. Viewers of forensic dramas were not more likely to convict the defendant when forensic evidence was presented and not less likely to convict when only testimonial evidence was presented. The only significant predictor of the defendant's culpability when scientific evidence was presented was participants' ratings of the reliability of scientific evidence. Results from the present study lend no support to the existence of the CSI effect in Hong Kong.

    Full Text Available In the article diff erent forms of mystical experience in the XVIIIth–XIXth centuries Russia are reconstructed on the basis of the sources from Rosicrucian funds of DMS RSL. These sources describe both Rosicrucian and non-Rosicrucian experience and represent mystical enthusiasm of diff erent social groups in Russia. Rosicrucians collected these records in volumes, containing mystical diaries, letters, descriptions of visions etc., which could be classifi ed as special genre of Rosicrucian literature — «mystical testimonies». Article provides classifi cation of such forms of experience based on four criteria: modes of perception, object of experience, its content and relation to mystical practices. The basic modes of mystical perception were: audial, visual, olfactory, tactile, gustatory and synesthetic. Objects of mystical experience could be divided into two groups: characters from New Testament and supernatural beings and powers, both good and evil. Content of mystical experience includes instructions, prophecies and revelations. Instructions could be spiritual or practical (medical ones. Prophecies concerned historical events, such as war with Napoleon or Decembrists revolt. Revelations concerned structure of the universe, spiritual world and secrets of afterlife. All these experiences could be spontaneous (like dreams or hallucinations or induced by some practices (for example prayer or «inner conversion». In the conclusion three main features of these forms of mystical experience are distinguished: their Christian nature, strong connection with Masonic-Rosicrucian worldview and their individual nature

  3. Testimony presented to the Committee on Science and Technology's Subcommittee on Environment and the Atmosphere

    Energy Technology Data Exchange (ETDEWEB)

    Richmond, C.R.


    This report contains the basis for oral testimony to the House Committee on Science and Technology's Subcommittee on Environment and the Atmosphere in November 1975. The subject of the hearings was ''Effects and Costs of Long-term Exposure to Low Levels of Manmade Pollutants'' and the purpose of the hearings was to increase the awareness of low-level pollution and its impacts on human health, agriculture and climate. This report contains information related to impacts of low-level pollutants on human health. I have attempted to point out the major adverse health effects (e.g., carcinogenic, mutagenic and teratogenic) that may result from chronic exposure to low-level pollutants. Also addressed are important questions such as what do we know about dose-response relations for chronic exposure to pollutants and how can we establish comparisons with knowledge obtained from exposure to ionizing radiations. The report also considers the wisdom of extrapolating from health effects data obtained from acute, high-level exposures to chronic, low-level exposure conditions. Lastly, a few examples of the societal costs related to low-level pollutant exposure are presented. (auth)

  4. Role of dental expert in forensic odontology. (United States)

    Verma, Anoop K; Kumar, Sachil; Rathore, Shiuli; Pandey, Abhishek


    Forensic dentistry has become an integral part of forensic science over the past 100 years that utilizes dental or oro-facial findings to serve the judicial system. This has been due to the dedication of people like Gustafson's, Keiser-Nielson, and Suzuki for this field. They established the essential role which forensic dentistry plays mainly in the identification of human remains. The tooth has been used as weapons and under certain circumstances, may leave information about the identity of the biter. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize mal practice, negligence, fraud or abuse, and identity of unknown individuals. This paper will try to summarize the various roles of dental experts in forensic medicine.

  5. Outlier Detection and Explanation for Domain Experts

    DEFF Research Database (Denmark)

    Micenková, Barbora

    In many data exploratory tasks, extraordinary and rarely occurring patterns called outliers are more interesting than the prevalent ones. For example, they could represent frauds in insurance, intrusions in network and system monitoring, or motion in video surveillance. Decades of research have...... produced various outlier detection algorithms. It is commonly known that these algorithms are difficult to apply and interpret in practice for a variety of reasons. In this thesis we propose novel algorithms that provide robust performance, support for validation and interpretability for outlier detection...... in practice and we empirically evaluate them on synthetic and real world data sets. First, we tackle the problem that most algorithms leave the end user without any explanation of how or why the identified outliers deviate. Such knowledge is important for domain experts in order to be able to validate...

    The NorthernSTAR Building America Partnership held an expert meeting on Foundations–Research Results on November 15, 2011, in Minneapolis, MN. Audience participation was actively encouraged during each presentation to uncover needs and promote dialog among researchers and industry professionals. Key results were: greater understanding of the role of moisture transport through foundation and insulation materials and its potential impact on building durability; greater understanding of the role of foundation type in the process of selecting an insulation system for energy performance and building durability; need for research to quantify the risks associated with insulation processes to better enable users to weigh costs and benefits against the existing conditions of a home; need for improved performance modeling capabilities that address variations in foundation types and soil conditions.

  12. Lay and Expert Perceptions of Planetary Protection (United States)

    Race, Margaret S.; MacGregor, Donald G.; Slovic, Paul


    As space scientists and engineers plan new missions to Mars and other planets in our solar system, they will face critical questions about the potential for biological contamination of planetary surfaces. In a society that places ever-increasing importance on the role of public involvement in science and technology policy, questions about risks of biological contamination will be examined and debated in the media, and will lead to the formation of public perceptions of planetary-contamination risks. These perceptions will, over time, form an important input to the development of space policy. Previous research in public and expert perceptions of technological risks and hazards has shown that many of the problems faced by risk-management organizations are the result of differing perceptions of risk (and risk management) between the general public and scientific and technical experts. These differences manifest themselves both as disagreements about the definition (and level) of risk associated with a scientific, technological or industrial enterprise, and as distrust about the ability of risk-management organizations (both public and private) to adequately protect people's health and safety. This report presents the results of a set of survey studies designed to reveal perceptions of planetary exploration and protection from a wide range of respondents, including both members of the general public and experts in the life sciences. The potential value of this research lies in what it reveals about perceptions of risk and benefit that could improve risk-management policies and practices. For example, efforts to communicate with the public about Mars sample return missions could benefit from an understanding of the specific concerns that nonscientists have about such a mission by suggesting areas of potential improvement in public education and information. Assessment of both public and expert perceptions of risk can also be used to provide an advanced signal of

  13. Expert chess memory: revisiting the chunking hypothesis. (United States)

    Gobet, F; Simon, H A


    After reviewing the relevant theory on chess expertise, this paper re-examines experimentally the finding of Chase and Simon (1973a) that the differences in ability of chess players at different skill levels to copy and to recall positions are attributable to the experts' storage of thousands of chunks (patterned clusters of pieces) in long-term memory. Despite important differences in the experimental apparatus, the data of the present experiments regarding latencies and chess relations between successively placed pieces are highly correlated with those of Chase and Simon. We conclude that the two-second inter-chunk interval used to define chunk boundaries is robust, and that chunks have psychological reality. We discuss the possible reasons why Masters in our new study used substantially larger chunks than the Master of the 1973 study, and extend the chunking theory to take account of the evidence for large retrieval structures (templates) in long-term memory.

  15. Blood Donor Deferrals by Expert System (United States)

    Sorace, James M.; Berman, Jules J.; Brown, Lawrence A.; Moore, G. William


    Blood collection facilities have recently witnessed a substantial increase in the number of different tests used to detect infectious disease in donor populations. These facilities are also experiencing an increasingly stringent regulatory effort on the part of the Food and Drug Administration to determine the validity of the software used to handle this information. This report describes a precedence-based inference program (PRELOG) and a modular expert system used to determine a donor's suitability for continued donations (donor deferrals), and whether the donated unit can be released for transfusion. PRELOG accepts ternary logic input, in which test results are allowed to be positive, negative, or undetermined; and allows one to assign precedence values to the logic rules. These features enable programs to be written in a shorter, more error-resistant manner. A comparison between PRELOG and PROLOG is included, and the utility of this approach in producing and validating blood bank software is discussed.

  16. Expert system for spacecraft command and control (United States)

    Wagner, R. E.

    The application of AI techniques to the automation of ground control functions in the defense satellite communication system (DSCS) is described. The aim of this effort is to lower the vulnerability of the DSCS to attack; a first step is the design of software for spacecraft maintenance and control. The benefits of automation and the need for high-level implementation are reviewed. A knowledge-based or expert approach was chosen to automate telemetry-interpretation, trend-analysis, anomaly-resolution, and status-maintenance functions now performed solely by operators; and a design concept was developed to meet the requirements of extendability, simplicity, and explicitness. Rule-based and logic-based knowledge-representation schemes, and data-driven and goal-driven control strategies are compared. The programming tools developed by the different organizations participating in the AI effort are indicated in a table.

  17. Glyphosate rodent carcinogenicity bioassay expert panel review. (United States)

    Williams, Gary M; Berry, Colin; Burns, Michele; de Camargo, Joao Lauro Viana; Greim, Helmut


    Glyphosate has been rigorously and extensively tested for carcinogenicity by administration to mice (five studies) and to rats (nine studies). Most authorities have concluded that the evidence does not indicate a cancer risk to humans. The International Agency for Research on Cancer (IARC), however, evaluated some of the available data and concluded that glyphosate probably is carcinogenic to humans. The expert panel convened by Intertek assessed the findings used by IARC, as well as the full body of evidence and found the following: (1) the renal neoplastic effects in males of one mouse study are not associated with glyphosate exposure, because they lack statistical significance, strength, consistency, specificity, lack a dose-response pattern, plausibility, and coherence; (2) the strength of association of liver hemangiosarcomas in a different mouse study is absent, lacking consistency, and a dose-response effect and having in high dose males only a significant incidence increase which is within the historical control range; (3) pancreatic islet-cell adenomas (non-significant incidence increase), in two studies of male SD rats did not progress to carcinomas and lacked a dose-response pattern (the highest incidence is in the low dose followed by the high dose); (4) in one of two studies, a non-significant positive trend in the incidence of hepatocellular adenomas in male rats did not lead to progression to carcinomas; (5) in one of two studies, the non-significant positive trend in the incidence of thyroid C-cell adenomas in female rats was not present and there was no progression of adenomas to carcinomas at the end of the study. Application of criteria for causality considerations to the above mentioned tumor types and given the overall weight-of-evidence (WoE), the expert panel concluded that glyphosate is not a carcinogen in laboratory animals.

  18. Transfer of expert visual anticipation to a similar domain. (United States)

    G Moore, Christopher; Müller, Sean


    The experiment reported in this paper examined the capability of expert and near-expert baseball batters and novices to transfer anticipatory skill to a cricket batting prediction task. A video-simulation temporal occlusion paradigm was used to first assess the anticipatory skill of expertise groups in a baseball batting prediction task (learning sport) and, second, to assess the capability of expertise groups to transfer anticipation skill to a cricket batting prediction task (transfer sport). Results showed that expert and near-expert baseball batters were superior to novices at anticipating pitch type based upon pre-ball-flight advance information. Only expert baseball batters were capable of transferring their anticipatory skill to predict delivery type based upon advance information in the bowler's action, whilst near-experts and novices relied upon ball-flight information. The findings extend understanding of transfer of learning in the motor domain and some theoretical/empirical concepts of transfer.

  19. Ask-the-expert: Active Learning Based Knowledge Discovery Using the Expert (United States)

    Das, Kamalika; Avrekh, Ilya; Matthews, Bryan; Sharma, Manali; Oza, Nikunj


    Often the manual review of large data sets, either for purposes of labeling unlabeled instances or for classifying meaningful results from uninteresting (but statistically significant) ones is extremely resource intensive, especially in terms of subject matter expert (SME) time. Use of active learning has been shown to diminish this review time significantly. However, since active learning is an iterative process of learning a classifier based on a small number of SME-provided labels at each iteration, the lack of an enabling tool can hinder the process of adoption of these technologies in real-life, in spite of their labor-saving potential. In this demo we present ASK-the-Expert, an interactive tool that allows SMEs to review instances from a data set and provide labels within a single framework. ASK-the-Expert is powered by an active learning algorithm for training a classifier in the backend. We demonstrate this system in the context of an aviation safety application, but the tool can be adopted to work as a simple review and labeling tool as well, without the use of active learning.

    Okubo, S. (Univ. of Tokyo, Tokyo (Japan). Faculty of Engineering)


    A tunnel boring machine (TBM) shows extreme lowering in mean penetration rate if it is not properly applied and used, therefore, it is required to discuss the applicability of TBM in advance. In this papaer, the work results presented up to now and knowledge concerning to TBM performances are collected and implemented in a computer program which is called an expert system for applicability of TBM. In this expert system, input parameters are tunnel length, tunnel diameter, maximum curvature, dip, uniaxial compressive strength etc., and penetration rate, normal force, rolling force etc. are deduced together with the appraisal and recommendation for users. Through the several case studies, it was found that the developed expert system gives the appropriate results specially for the tunnels excavated in North America and Europe. In cases of tunnels excavated in Japan, the estimated penetration rate is far less than the actual result. Consideration for complicated environments and surroundings differing from country to country may be remained for future. 31 refs., 4 figs., 6 tabs.

    Borgohain, Rajdeep; Sanyal, Sugata


    The use of Artificial Intelligence is finding prominence not only in core computer areas, but also in cross disciplinary areas including medical diagnosis. In this paper, we present a rule based Expert System used in diagnosis of Cerebral Palsy. The expert system takes user input and depending on the symptoms of the patient, diagnoses if the patient is suffering from Cerebral Palsy. The Expert System also classifies the Cerebral Palsy as mild, moderate or severe based on the presented symptoms.

  2. The Delphi Method Online: Medical Expert Consensus Via the Internet


    Cam, Kenneth M.; McKnight, Patrick E.; Doctor, Jason N


    Delphi is an expert consensus method. The theory behind the Delphi method is that the interaction of experts may lead to a reduction in individual bias. We have developed software that carries out all aspects of the Delphi method via the Internet. The Delphi method online consists of three components: 1) authorship, 2) interactive polling, and 3) reporting/results. We hope that researchers use this tool in future medical expert systems.

    A.A.L.C. Amarathunga


    Full Text Available Abstract Dermatology is a one of major session of medicine that concerned with the diagnosis and treatment of skin diseases. Skin diseases are the most common form of disease in humans. Recently many of researchers have advocated and developed the imaging of human vision or in the loop approach to visual object recognition. This research paper presents a development of a skin diseases diagnosis system which allows user to identify diseases of the human skin and to provide advises or medical treatments in a very short time period. For this purpose user will have to upload an image of skin disease to our system and answer questions based on their skin condition or symptoms. It will be used to detect diseases of the skin and offer a treatment recommendation. This system uses technologies such as image processing and data mining for the diagnosis of the disease of the skin. The image of skin disease is taken and it must be subjected to various preprocessing for noise eliminating and enhancement of the image. This image is immediately segmentation of images using threshold values. Finally data mining techniques are used to identify the skin disease and to suggest medical treatments or advice for users. This expert system exhibits disease identification accuracy of 85 for Eczema 95 for Impetigo and 85 for Melanoma.

  7. Expert systems guide biological phosphorus removal

    Energy Technology Data Exchange (ETDEWEB)

    Krichten, D.J.; Wilson, K.D.; Tracy, K.D. (Air Products and Chemicals, Inc., Allentown, PA (United States))


    There is a large body of knowledge regarding optimum control strategies for new secondary wastewater treatment technology using an anaerobic selector to provide biological phosphorus removal. However, because the selector technology is new and the concepts differ somewhat from those used in conventional activated sludge wastewater treatment, a method of communicating this knowledge to plant operators is needed. Traditional methods such as classroom training and operating manuals are of limited effectiveness. The commonplace availability and low cost of the personal computer (PC) makes it practical to use a computer program to communicate the type of information required to control a wastewater treatment plant. Knowledge-based systems technology, commonly referred to as expert systems (ES) technology, is easy to use, provides useful information regarding a consistent control strategy, relieves the anxiety associated with learning a new process,' and provides instruction for inexperienced personnel. ES technology does not require special formatted input and is therefore easily accessible. All information required by the program is readily available through routine laboratory analysis, common plant instrumentation, or direct user observation. The program was designed for all levels of computer users and will run on all IBM-compatible or Apple MacIntosh systems.

  11. Expert Panel Elicitation of Seismicity Following Glaciation in Sweden

    Energy Technology Data Exchange (ETDEWEB)

    Hora, Stephen; Jensen, Mikael (eds.)


    The Swedish Radiation Protection Authority, the Swedish Nuclear Power Inspectorate and the Swedish Nuclear Fuel and Waste Management Company have jointly carried out a project on expert panel elicitation on the issue of glacial induced Swedish earthquakes. Following a broad nomination procedure, 5 experts were chosen by a selection committee of 4 professors within Earth sciences disciplines. The 5 experts presented judgments about the frequency of earthquakes greater the magnitude 6 within 10 km for two Swedish sites, Oskarshamn and Forsmark, in connection with a glaciation cycle. The experts' median value vas 0,1 earthquakes for one glaciation cycle.

  12. Expert memory: a comparison of four theories. (United States)

    Gobet, F


    This paper compares four current theories of expertise with respect to chess players' memory: Chase and Simon's chunking theory, Holding's SEEK theory, Ericsson and Kintsch's long-term working memory theory, and Gobet and Simon's template theory (Chase, W.G., Simon, H.A., 1973a. Perception in chess. Cognitive Psychology 4, 55-81; Holding, D.H., 1985. The Psychology of Chess Skill. Erlbaum, Hillsdale, NJ; Ericsson, K.A., Kintsch, W., 1995. Long-term working memory. Psychological Review 102, 211-245; Gobet, F., Simon, H.A., 1996b. Templates in chess memory: a mechanism for recalling several boards. Cognitive Psychology 31, 1-40). The empirical areas showing the largest discriminative power include recall of random and distorted positions, recall with very short presentation times, and interference studies. Contrary to recurrent criticisms in the literature, it is shown that the chunking theory is consistent with most of the data. However, the best performance in accounting for the empirical evidence is obtained by the template theory. The theory, which unifies low-level aspects of cognition, such as chunks, with high-level aspects, such as schematic knowledge and planning, proposes that chunks are accessed through a discrimination net, where simple perceptual features are tested, and that they can evolve into more complex data structures (templates) specific to classes of positions. Implications for the study of expertise in general include the need for detailed process models of expert behavior and the need to use empirical data spanning the traditional boundaries of perception, memory, and problem solving.

  13. Expert views from Poland and Estonia

    Directory of Open Access Journals (Sweden)

    Kaja Põlluste


    Full Text Available Background . Home care (HC is placed between the health and social welfare systems, and the clients of HC mostly need health services. Along with other providers, family doctors (FDs are usually involved in the provision of care. Objectives. This paper aims to describe and compare the involvement of HC providers to elderly and disabled persons in Poland and Estonia. Material and methods . This study is part of the international project EURHOMA P (Mapping Professional Home Care in Europe. Data was collected in 2008–2010. Experts from different areas of health and social care were queried by using a questionnaire containing structured case narratives, which were hypothetical descriptions of the situations of elderly or disabled persons living at home and in need of care. Results. There are a number of HC services, e.g. nursing, medical and social, available in both countries. The application for HC is mostly made by the patient or a close family member; the point of entry to HC can differ and depends on the client’s primary problem. FDs, together with social workers, play an important role in the provision of HC services in both countries. However, due to a shortage of round-the-clock professional services at a client’s home, families are also expected to play a large role in providing HC . Conclusions . Health care professionals, mainly those working in primary health care, play a remarkable role in access to and provision of HC services. Nevertheless, responsibility for 24-hour care lies, to a large extent, with the client’s immediate family. This situation seems to be typical in Eastern European countries.

  14. Experts bodies, experts minds: How physical and mental training shape the brain

    Directory of Open Access Journals (Sweden)

    Ursula eDebarnot


    Full Text Available Skill learning is the improvement in perceptual, cognitive, or motor performance following practice. Expert performance levels can be achieved with well-organized knowledge, using sophisticated and specific mental representations and cognitive processing, applying automatic sequences quickly and efficiently, being able to deal with large amounts of information, and many other challenging task demands and situations that otherwise paralyze the performance of novices. The neural reorganizations that occur with expertise reflect the optimization of the neurocognitive resources to deal with the complex computational load needed to achieve peak performance. As such, capitalizing on neuronal plasticity, brain modifications take place over time-practice and during the consolidation process. One major challenge is to investigate the neural substrates and cognitive mechanisms engaged in expertise, and to define expertise from its neural and cognitive underpinnings. Recent insights showed that many brain structures are recruited during task performance, but only activity in regions related to domain-specific knowledge distinguishes experts from novices. The present review focuses on three expertise domains placed across a motor to mental gradient of skill learning: sequential motor skill, mental simulation of the movement (motor imagery, and meditation as a paradigmatic example of pure mental training. We first describe results on each specific domain from the initial skill acquisition to the achieving of expert performance, including recent results on the corresponding underlying neural mechanisms. We then discuss differences and similarities between these domains with the aim to identify the highlights of the neurocognitive processes underpinning expertise, and conclude with suggestions for future research.

  15. Expert performance on a virtual reality simulation system. (United States)

    Wierinck, Els R; Puttemans, Veerle; Swinnen, Stephan P; van Steenberghe, Daniel


    The objective of this research was to determine if the essence of expert performance could be captured on a virtual reality simulation system. Six experts in operative dentistry, six experts in periodontology, and six novice dental students performed a Class II tooth preparation task on the lower left second premolar. All subjects performed a pre-test to assess the basic skill level of each group. During the (limited) training component of the study, the three groups practiced three tooth preparations and received augmented feedback. At both a one-minute and one-day interval, subjects performed a final test in the absence of augmented feedback. All preparations were graded by the simulation system. The results showed at pre-test a significantly better performance of the experts in operative dentistry as compared to the novices. During the practice (acquisition) phase, the experts in operative dentistry outperformed both the periodontologists and novices, whereas the experts in periodontology performed more accurately than the novices. After one minute and one day following practice, similar results were obtained. Retention performance was most accurate after a one-day delay. Based on these results, the simulator appears to be a valid and reliable tool to capture expert performance. It is an effective screening device for assessing the level of expert performance.

  3. Expert systems applications for space shuttle payload integration automation (United States)

    Morris, Keith


    Expert systems technologies have been and are continuing to be applied to NASA's Space Shuttle orbiter payload integration problems to provide a level of automation previously unrealizable. NASA's Space Shuttle orbiter was designed to be extremely flexible in its ability to accommodate many different types and combinations of satellites and experiments (payloads) within its payload bay. This flexibility results in differnet and unique engineering resource requirements for each of its payloads, creating recurring payload and cargo integration problems. Expert systems provide a successful solution for these recurring problems. The Orbiter Payload Bay Cabling Expert (EXCABL) was the first expert system, developed to solve the electrical services provisioning problem. A second expert system, EXMATCH, was developed to generate a list of the reusable installation drawings available for each EXCABL solution. These successes have proved the applicability of expert systems technologies to payload integration problems and consequently a third expert system is currently in work. These three expert systems, the manner in which they resolve payload problems and how they will be integrated are described.

  7. Sources of correlation between experts: Empirical results from two extremes

    Energy Technology Data Exchange (ETDEWEB)

    Meyer, M.A.; Booker, J.M.


    Through two studies, this report seeks to identify the sources of correlation, or dependence, between experts' estimates. Expert estimates are relied upon as sources of data whenever experimental data is lacking, such as in risk analyses and reliability assessments. Correlation between experts is a problem in the elicitation and subsequent use of subjective estimates. Until now, there have been no data confirming sources of correlation, although the experts' background is commonly speculated to be one. Two different populations of experts were administered questions in their areas of expertise. Data on their professional backgrounds and means of solving the questions were elicited using techniques from educational psychology and ethnography. The results from both studies indicate that the way in which an expert solves the problem is the major source of correlation. The experts' background can not be shown to be an important source of correlation nor to influence his choice of method for problem solution. From these results, some recommendations are given for the elicitation and use of expert opinion.

  16. The Role of Experts in a Democratic Society

    Directory of Open Access Journals (Sweden)

    Ivan Cerovac


    Full Text Available Democratic procedures are characterized by the equal status of all citizens participating in the decision-making process. This procedural fairness represents one of the central aspects of democracy's legitimacy-generating potential and should not be rejected or weakened. However, citizens specialize in different areas and inevitably some citizens become more competent (i.e. become experts regarding some political issues. Democratic procedure would loose much of its appeal if it would be unable to take advantage of the experts' knowledge. In this paper I follow Kitcher and Christiano in embracing a form of division of epistemic (and political labour - citizens and their political representatives should deliberate and set aims the political community is to pursue, while experts and policy-makers should devise means (laws, public policies and political decisions needed to achieve the aims set by citizens. However, citizens should not blindly trust the experts - their epistemic authority is derivative and social and academic networks and structures should be employed in order to enable citizens to assess and evaluate experts' competence, but experts' impartiality regarding the issue at hand as well. Consequently, the process should not be unidirectional: experts should be able to help citizens select feasible and coherent aims, while citizens should be able to help experts in creating policies and decisions. Deliberative democracy is an appropriate political setting for this kind of bidirectional communication.

  4. A new Expert Finding model based on Term Correlation Matrix

    Directory of Open Access Journals (Sweden)

    Ehsan Pornour


    Full Text Available Due to the enormous volume of unstructured information available on the Web and inside organization, finding an answer to the knowledge need in a short time is difficult. For this reason, beside Search Engines which don’t consider users individual characteristics, Recommender systems were created which use user’s previous activities and other individual characteristics to help users find needed knowledge. Recommender systems usage is increasing every day. Expert finder systems also by introducing expert people instead of recommending information to users have provided this facility for users to ask their questions form experts. Having relation with experts not only causes information transition, but also with transferring experiences and inception causes knowledge transition. In this paper we used university professors academic resume as expert people profile and then proposed a new expert finding model that recommends experts to users query. We used Term Correlation Matrix, Vector Space Model and PageRank algorithm and proposed a new hybrid model which outperforms conventional methods. This model can be used in internet environment, organizations and universities that experts have resume dataset.

  6. Simplified Expert Elicitation Procedure for Risk Assessment of Operating Events

    Energy Technology Data Exchange (ETDEWEB)

    Ronald L. Boring; David Gertman; Jeffrey Joe; Julie Marble; William Galyean; Larry Blackwood; Harold Blackman


    This report describes a simplified, tractable, and usable procedure within the US Nuclear Regulator Commission (NRC) for seeking expert opinion and judgment. The NRC has increased efforts to document the reliability and risk of nuclear power plants (NPPs) through Probabilistic Risk Assessment (PRA) and Human Reliability Analysis (HRA) models. The Significance Determination Process (SDP) and Accident Sequence Precursor (ASP) programs at the NRC utilize expert judgment on the probability of failure, human error, and the operability of equipment in cases where otherwise insufficient operational data exist to make meaningful estimates. In the past, the SDP and ASP programs informally sought the opinion of experts inside and outside the NRC. This document represents a formal, documented procedure to take the place of informal expert elicitation. The procedures outlined in this report follow existing formal expert elicitation methodologies, but are streamlined as appropriate to the degree of accuracy required and the schedule for producing SDP and ASP analyses.

  7. Epistemology applied to conclusions of expert reports. (United States)

    Lucena-Molina, Jose-Juan


    It is believed that to build a robust reasoning logic to make probabilistic inferences in forensic science from a merely mathematical or logistical viewpoint is not enough. Mathematical logic is the positive science of reasoning and as for that it is only interested in the positive calculus of its validity, regardless any prior ontological assumption. But without a determined ontology and epistemology which imply to define the concepts that they will use, it seems difficult that the proposed scientifically correct mathematical solution be successful as a European standard for making conclusions in forensic reports because it has to be based on judicial language. Forensic experts and Courts are not interested in the development of a positive science but in a practical science: in clarifying whether certain known facts are related to a possible crime. Therefore, not only the coherence of the demonstrative logic reasoning used (logic of propositions) is important, but also the precision of the concepts used by language and consistency among them in reasoning (logic of concepts). There is a linguistic level essential for a successful communication between the forensic practitioner and the Court which is mainly related, in our opinion, to semantics and figures of speech. The first one is involved because words used in forensic conclusions often have different meanings - it is said that they are polysemic - and the second one because there is often metonymy as well. Besides, semantic differences among languages regarding words with the same etymological root add another difficulty for a better mutual understanding. The two main European judicial systems inherit a wide and deep culture related to evidence in criminal proceedings and each of them has coined their own terminology but there are other two more abstract levels such as logical and epistemological, where we can find solid arguments by which terms used at legal level on conclusions of forensic reports could be

  8. [Free sorting task of speech disorders by expert and non-expert listeners]. (United States)

    Woisard, V; Gaillard, P; Duez, D


    Understood the strategies underlying the perception of speech motor disorders (SMD) is useful for the management of people with this kind of disorders. Our hypothesis was that intelligibility of speech is a dramatic decision factor for the classification of speech production independently of the type of listeners. Two types of listeners: 15 experts (logopedists and phoniatricians), and 15 non experts (students in the field of heath care without any experience) participated at this study performing a free sorting task of 33 stimuli. The stimuli are a sentence readed by 13 control subjects and 20 subjects with a SMD of several kinds of etiologies. The methodology used for the analysis is the visualization of proximity trees by a sorting mathematical algorithm and the analysis of the free commentaries as a discourse. The results confirm that the degree of alteration of intelligibility is the main factor distributed in the sorts, but the reference to the "normality" is an other strong criteria and this notion is frequently associated with a description of the stimuli at a level of voice more than a level of speech. These results lead to a new hypothesis of a classification of perception of speech included a speech disorders, determined at an extremity by a comparison with a "prototype of normality" and at the other extremity by the characteristic of "intelligibility or understandibility" reinforcing some concepts of speech rehabilitation.

  10. The speleothem record from Sicily, an important palaeoclimate testimony in the heart of the Mediterranean: overview of current research (United States)

    Deininger, Michael; Vattano, Marco; McDermott, Frank; Frisia, Silvia; Borsato, Andrea; Frank, Norbert; Spötl, Christoph; Scholz, Denis; Di Maggio, Cipriano; Madonia, Giuliana


    Sicily is located in the heart of the Mediterranean and takes a strategic position between the western and eastern Mediterranean as well as between northern Africa and continental Europe. It is a place of a diverse and great cultural heritage that goes back many thousands of years; it had been colonised by Phoenicians, Carthaginians, Greeks and Romans in Ancient times and served as a trading post and granary - the latter particularly for the Romans. Climate change scenarios studies suggest that Mediterranean ecosystems could change into deserts as a consequence of shifting temperature and precipitation patterns unparalleled in the Holocene period (Guiot and Cramer, 2016). It is, therefore, essential to shed light on past precipitation changes to gain knowledge on the timing, dynamics and causes of these changes by making use of natural environmental archives (such as speleothems). This information is not only important for palaeoclimate data-model comparisons but can also give archaeologists a wealth of information when studying cultural transformations. Speleothems are valuable natural archives of past climatic and environmental conditions on the continents. Major strengths include their suitability for accurate U-series age determinations and their preservation of multiple quasi-independent climate proxies - that can be linked to precipitation changes. Hence, speleothems proxy time series from the Mediterranean can be regarded as an important testimony of past environmental and climate changes (including precipitation) that allow to provide answers to the aforementioned questions. Here we present first result of ongoing speleothem research on Sicily, with focuses on Pietrazzi cave (Grotta dei Pietrazzi) located west of Palermo. It developed in limestone (limestone consisting of bioclastic packstone/wackestones, fore reef coral rudstones (calcirudite) and calcarenites.) of the Calcare di Piano Battaglia Formation.

  12. Testimonies from Zaire. (United States)

    Hussein, A


    Tribal hatred and rivalry can contribute to the dislocation of many people and reduction in their social welfare. Assimilation into new areas is made difficult by limitations on resources: the results can be starvation, malnutrition, death, morbidity, prostitution and rape, and inadequate shelter and means of survival. In the fall of 1992, more than 150,000 Kasaians were forced to leave Zaire and travel to regions in the East and West Kasai by whatever means possible. Accounts of "repatriation" were given by women involved in the movement. One account describes the initial adjustment in 1991 of a nine-child family in Katanga; this family took in 10 refugee families until it became impossible to survive or get along with neighbors. The decision was made to take the one train out of the area to Kasai territory. The journey was difficult for the children who had to stand and did not have sufficient food or water. A two to three day trip took two weeks. The adjustment to the new village was a strange experience, after having lived with electricity and tap water. By March 1993, conditions had so deteriorated that Kasaian women were banned from economic activity of any kind, and young thugs brandishing knives and clubs hurt and killed Kasaian women and children. Houses were set on fire, and people were disposed without any shelter in the rainy season. Those with possessions sold them and bought food. Some tried to find food in abandoned fields, but were driven back by Katangan military personnel. Maize grains and maniac root were the only food options. Many became ill with kwashiorkor and dysentery, and as many as 35 people died daily. The Red Cross counted 640 deaths between March 20 and May 25, 1993. The hatred ran deep, and mixed marriages suffered. Most families left by train, but the conditions in Kananga were the same as in Kolwezi. Food rations were inadequate. The refugee camps had bottled water, but access meant a very long wait. There was no income and no facility to plan for the future.

  13. Multiple neural network approaches to clinical expert systems (United States)

    Stubbs, Derek F.


    We briefly review the concept of computer aided medical diagnosis and more extensively review the the existing literature on neural network applications in the field. Neural networks can function as simple expert systems for diagnosis or prognosis. Using a public database we develop a neural network for the diagnosis of a major presenting symptom while discussing the development process and possible approaches. MEDICAL EXPERTS SYSTEMS COMPUTER AIDED DIAGNOSIS Biomedicine is an incredibly diverse and multidisciplinary field and it is not surprising that neural networks with their many applications are finding more and more applications in the highly non-linear field of biomedicine. I want to concentrate on neural networks as medical expert systems for clinical diagnosis or prognosis. Expert Systems started out as a set of computerized " ifthen" rules. Everything was reduced to boolean logic and the promised land of computer experts was said to be in sight. It never came. Why? First the computer code explodes as the number of " ifs" increases. All the " ifs" have to interact. Second experts are not very good at reducing expertise to language. It turns out that experts recognize patterns and have non-verbal left-brain intuition decision processes. Third learning by example rather than learning by rule is the way natural brains works and making computers work by rule-learning is hideously labor intensive. Neural networks can learn from example. They learn the results

  14. Expert music performance: cognitive, neural, and developmental bases. (United States)

    Brown, Rachel M; Zatorre, Robert J; Penhune, Virginia B


    In this chapter, we explore what happens in the brain of an expert musician during performance. Understanding expert music performance is interesting to cognitive neuroscientists not only because it tests the limits of human memory and movement, but also because studying expert musicianship can help us understand skilled human behavior in general. In this chapter, we outline important facets of our current understanding of the cognitive and neural basis for music performance, and developmental factors that may underlie musical ability. We address three main questions. (1) What is expert performance? (2) How do musicians achieve expert-level performance? (3) How does expert performance come about? We address the first question by describing musicians' ability to remember, plan, execute, and monitor their performances in order to perform music accurately and expressively. We address the second question by reviewing evidence for possible cognitive and neural mechanisms that may underlie or contribute to expert music performance, including the integration of sound and movement, feedforward and feedback motor control processes, expectancy, and imagery. We further discuss how neural circuits in auditory, motor, parietal, subcortical, and frontal cortex all contribute to different facets of musical expertise. Finally, we address the third question by reviewing evidence for the heritability of musical expertise and for how expertise develops through training and practice. We end by discussing outlooks for future work. © 2015 Elsevier B.V. All rights reserved.

  15. Development of a Coal Quality Expert

    Energy Technology Data Exchange (ETDEWEB)



    ABB Power Plant Laboratories Combustion Engineering, Inc., (ABB CE) and CQ Inc. completed a broad, comprehensive program to demonstrate the economic and environmental benefits of using higher quality U.S. coals for electrical power generation and developed state-of-the-art user-friendly software--Coal Quality Expert (CQE)-to reliably predict/estimate these benefits in a consistent manner. The program was an essential extension and integration of R and D projects performed in the past under U.S. DOE and EPRI sponsorship and it expanded the available database of coal quality and power plant performance information. This software will permit utilities to purchase the lowest cost clean coals tailored to their specific requirements. Based on common interest and mutual benefit, the subject program was cosponsored by the U.S. DOE, EPRI, and eight U.S. coal-burning utilities. In addition to cosponsoring this program, EPN contributed its background research, data, and computer models, and managed some other supporting contracts under the terms of a project agreement established between CQ Inc. and EPRI. The essential work of the proposed project was performed under separate contracts to CQ Inc. by Electric Power Technologies (El?'T), Black and Veatch (B and V), ABB Combustion Engineering, Babcock and Wilcox (B and W), and Decision Focus, Inc. Although a significant quantity of the coals tied in the United States are now cleaned to some degree before firing, for many of these coals the residual sulfur content requires users to install expensive sulfur removal systems and the residual ash causes boilers to operate inefficiently and to require frequent maintenance. Disposal of the large quantities of slag and ash at utility plant sites can also be problematic and expensive. Improved and advanced coal cleaning processes can reduce the sulfur content of many coals to levels conforming to environmental standards without requiring post-combustion desulfurization systems.

  16. Expert Group Meeting on Population and Women. (United States)


    As part of the preparation for the up-coming International Conference on Population and Development sponsored by the UN, an expert group met in June 1992 in Botswana to consider issues related to population and women. Particular attention was devoted to gender equality, population, and development; reproductive health and the health of families; adolescent fertility, marriage, and reproductive health; family planning (FP) and FP programs; education of girls and women and the relationship of education to fertility, health, and welfare; women's economic activity and its relationship to demographic factors; and the relationship between women, population, and the environment. While both developed and developing countries were considered, the emphasis was on the latter. 32 recommendations for action were addressed primarily to governments and other social institutions and also to funding agencies. The recommendations call for a recognization that health and education are particularly critical for women. They ask for the development of gender-based analysis and assessment of development policies to discover their impact on women. Service delivery to women should be culturally appropriate, and women should be integrated into development initiatives and into management and policy-making levels of social institutions. Responsible parenthood should be promoted as should the assumption of familiar responsibilities by men. Women should have access to safe abortion services. Adolescents should receive the education necessary to protect their reproductive health, and a minimum marriage age should be adopted. FP programs should be appropriate to their clients and should provide safe methods of fertility regulation.

  17. Utilizing expert systems for satellite monitoring and control (United States)

    Hughes, Peter M.


    Spacecraft analysts in the spacecraft control center for the Cosmic Background Explorer (COBE) satellite are currently utilizing a fault-isolation expert system developed to assist in the isolation and correction of faults in the communications link. This system, the communication link expert assistance resource (CLEAR), monitors real time spacecraft and ground systems performance parameters in search of configuration discrepancies and communications link problems. If such a discrepancy or problem is isolated, CLEAR alerts the analyst and provides advice on how to resolve the problem swiftly and effectively. The CLEAR system is the first real time expert system to be used in the operational environment of a satellite control center at the NASA Goddard Space Flight Center. Clear has not only demonstrated the utility and potential of an expert system in the demanding environment of a satellite control center, but also has revealed many of the pitfalls and deficiencies of development of expert systems. One of the lessons learned from this and other initial expert system projects is that prototypes can often be developed quite rapidly, but operational expert systems require considerable effort. Development is generally a slow, tedious process that typically requires the special skills of trained programmers. Due to the success of CLEAR and several other systems in the control center domain, a large number of expert systems will certainly be developed to support control center operations during the early 1990's. To facilitate the development of these systems, a project was initiated to develop an integrated, domain-specific tool, the generic spacecraft analyst assistent (GenSAA), that alows the spacecraft analysts to rapidly create simple expert systems themselves. By providing a highly graphical point-and-select method of system development, GenSAA allows the analyst to utilize and/or modify previously developed rule bases and system components; thus, facilitating

  18. [Drafting expert opinion reports in medical liability processes]. (United States)

    Ulsenheimer, K


    In a medical liability process a medical expert takes on an outstanding position. He is the one process participant who preprograms the decision of the judge. However, he does not as such have an independent investigative competence and must understand his role as being an accessory to the judge. In view of this key role, the necessary expert competence and a basic legal knowledge, adequate preparation for the assignment and a meticulous study of the case file are indispensible. According to § 839 paragraph 1 of the German Civil Code (Bürgerliches Gesetzbuch, BGB) an expert witness nominated by a court of law is liable to compensate damages if he writes an incorrect expert opinion either deliberately or due to gross negligence. The expert witness must also be objective and unprejudiced towards the parties involved or the accused/defendant. Civil processes and criminal proceedings both have legal peculiarities which the expert witness must bear in mind. The foundation of the function as an expert witness in a civil process is the order of the court to take evidence which the expert must adhere to. In this case the parties must be considered as being equal before the law. In contrast the procedure in criminal processes follows the principle of official investigation and the absolute principle of in dubio pro reo. From this it follows that the evidence of causality must be proven with a probability close to certainty. Advice for the construction of expert opinion statements can be found in this article.

    Full Text Available Financial rating and ranking firms often use linguistic instead of numerical values. When input data are mostly qualitative and are based on subjective knowledge of experts, the Fuzzy Set Theory provides a solid mathematical model to represent and handle these data. The aim of this study is developing a fuzzy expert model to evaluate the performance of the pension funds by using their risk and return values. The method is used for evaluating the performance of the randomly selected of twenty seven Turkish pension funds. The obtained results proved that the fuzzy expert system is appropriate and consistent for performance evaluation.

  1. Stochastic population forecasts based on conditional expert opinions. (United States)

    Billari, F C; Graziani, R; Melilli, E


    The paper develops and applies an expert-based stochastic population forecasting method, which can also be used to obtain a probabilistic version of scenario-based official forecasts. The full probability distribution of population forecasts is specified by starting from expert opinions on the future development of demographic components. Expert opinions are elicited as conditional on the realization of scenarios, in a two-step (or multiple-step) fashion. The method is applied to develop a stochastic forecast for the Italian population, starting from official scenarios from the Italian National Statistical Office.

  5. [Othello's error again: application of the source monitoring model in the assessment of testimony credibility and the influence of emotional stress]. (United States)

    Bembibre Serrano, Judit; Higueras Cortés, Lorenzo


    Othello's error again: Application of the source monitoring model in the assessment of testimony credibility and the influence of emotional stress. Two experiments, in which 240 individuals, matched in sex, were interviewed by 8 psychologists and 10 police officers, were carried out to check whether the categories of the source monitoring model help to distinguish between a true and a false testimony. In the first experiment, lies were meant to exonerate a criminal (a rapist) and, in the second one, the goal was to accuse an innocent person, a condition not described in the literature about the application of the model. In both cases, we assessed the emotional state of the interviewees using the Spanish version of the Profile of Moods States (POMS). The results suggest that this model is more effective when the person who has been instructed to lie is subjected to a stressful emotional situation, that is, when a lie wrongly blames criminal actions on an innocent person. The forensic importance of these results is discussed.

  6. Recognizing the importance of conversation between experts and non-experts in science communication (United States)

    Rushlow, C. R.; Soderquist, B.; Cohn, T.; Eitel, K.


    Science communication is often perceived by scientists as the flow of information from experts to non-experts, and institutions have responded by providing science communication training that focuses on best practices for disseminating information. This unidirectional approach neglects a key component of science communication: scientists must understand the needs and values of the stakeholders for whom they are producing information, whether the stakeholders are community members, resource managers, or policy makers. We designed an activity for graduate students enrolled in a science communication class at the McCall Outdoor Science School to both alert them to this misconception, and to give them an opportunity to rectify it. Over the course of 24-hours, we challenged students to have a conversation about climate change with someone they encountered in the community of McCall, ID. Using material from their conversations, students created a story in podcast or video form to share with the class. Through reflecting on this activity, students experienced a change in their perceptions of their identities as science communicators. Many students expressed an increased interest in listening to the stories of community members to learn more about the community's needs and values. We repeated the activity with early career scientists attending a climate workshop in McCall offered by the USGS Northwest Climate Science Center, focusing our evaluation around the science identity model of Carlone and Johnson (2007). Evaluations suggest that participants recognized their role as scientists in not only to providing information, but also in listening to the values and needs of the people for whom they are working. We believe this understanding is fundamental to being a good science communicator and ensuring that science remains relevant to communities.

  7. When experts disagreed, who was correct? A comparison of PCL-R scores from independent raters and opposing forensic experts. (United States)

    Rufino, Katrina A; Boccaccini, Marcus T; Hawes, Samuel W; Murrie, Daniel C


    Researchers recently found that Psychopathy Checklist-Revised (PCL-R; Hare, 2003) scores reported by state experts were much higher than those reported by defense experts in sexually violent predator cases pursued for civil commitment (Murrie, Boccaccini, Johnson, & Janke, 2008), which raised the question of which scores were more accurate. In this study, two independent raters rescored the PCL-R from file review for 44 offenders from that sample who had opposing evaluator scores (allegiance cases) and 44 who had state expert, but not defense expert, scores (comparison cases). The independent raters agreed with one another in their scoring of the allegiance and comparison cases (Intraclass Correlation Coefficient [ICC] ICCA,1 = .95), but they disagreed with both state (ICCA,1 = .29) and defense (ICCA,1 = .14) experts in the allegiance cases. Agreement was stronger between state experts and independent raters for the comparison cases (ICCA,1 = .63), but the independent raters assigned significantly higher PCL-R scores than experts for both the allegiance and comparison cases. These findings suggest that offenders who were selected for rescoring by the defense may have been more difficult to score. Findings also raise questions about the extent to which PCL-R scores based on correctional file review only are comparable to those based on file and interview.

  9. Tuning Expert Systems for Cost-Sensitive Decisions

    Directory of Open Access Journals (Sweden)

    Atish P. Sinha


    Full Text Available There is currently a growing body of research examining the effects of the fusion of domain knowledge and data mining. This paper examines the impact of such fusion in a novel way by applying validation techniques and training data to enhance the performance of knowledge-based expert systems. We present an algorithm for tuning an expert system to minimize the expected misclassification cost. The algorithm employs data reserved for training data mining models to determine the decision cutoff of the expert system, in terms of the certainty factor of a prediction, for optimal performance. We evaluate the proposed algorithm and find that tuning the expert system results in significantly lower costs. Our approach could be extended to enhance the performance of any intelligent or knowledge system that makes cost-sensitive business decisions.

  13. Parallelism in backward-chained expert systems - Experimental results (United States)

    Hall, Lawrence O.


    There are many applications which may be done by an expert system in real time, if the system is capable of real-time response. The LISP and PROLOG-based expert systems have typically been too slow for real-time response. This has led to an effort to use other languages, the development of fast pattern matching techniques and other methods of improving the speed of expert systems. Another approach to developing faster expert systems is to make use of the emerging parallel processing computer technology. A further use for parallelism is to allow reasonable response time for large knowledge bases. The size of knowledge bases may become as large as 20,000 chunks of knowledge (and more) in the near future in medical and space applications. This paper describes the use of parallel processing in the EMYCIN backward chained rule-based model.

  14. Segmentation and accuracy in copying and drawing: experts and beginners. (United States)

    Tchalenko, John


    As part of an ongoing investigation into real-world copying and drawing, I recorded the eye-hand drawing strategies of 16 subjects with drawing experiences ranging from expert to novice while they copied a line drawing of a standing nude. The experts produced accurate copies whereas all the beginners produced marked inaccuracies of overall scaling, proportion and shape. Analysis of eye and hand movements showed that the experts alone segmented the original drawing into simple line sections that were copied one at a time using a direct eye-hand strategy not requiring intermediary encoding to visual memory. The results suggest that segmentation into simple lines defines the task-specific process of accurate copying, and that this process is restricted to experts, i.e. acquired through training and practice. Additional preliminary tests also suggest that a similar process may apply to drawing a model from life.

  16. Short-term leprosy forecasting from an expert opinion survey.

    Directory of Open Access Journals (Sweden)

    Michael S Deiner

    Full Text Available We conducted an expert survey of leprosy (Hansen's Disease and neglected tropical disease experts in February 2016. Experts were asked to forecast the next year of reported cases for the world, for the top three countries, and for selected states and territories of India. A total of 103 respondents answered at least one forecasting question. We elicited lower and upper confidence bounds. Comparing these results to regression and exponential smoothing, we found no evidence that any forecasting method outperformed the others. We found evidence that experts who believed it was more likely to achieve global interruption of transmission goals and disability reduction goals had higher error scores for India and Indonesia, but lower for Brazil. Even for a disease whose epidemiology changes on a slow time scale, forecasting exercises such as we conducted are simple and practical. We believe they can be used on a routine basis in public health.

  17. Expert system for controlling plant growth in a contained environment (United States)

    May, George A. (Inventor); Lanoue, Mark Allen (Inventor); Bethel, Matthew (Inventor); Ryan, Robert E. (Inventor)


    In a system for optimizing crop growth, vegetation is cultivated in a contained environment, such as a greenhouse, an underground cavern or other enclosed space. Imaging equipment is positioned within or about the contained environment, to acquire spatially distributed crop growth information, and environmental sensors are provided to acquire data regarding multiple environmental conditions that can affect crop development. Illumination within the contained environment, and the addition of essential nutrients and chemicals are in turn controlled in response to data acquired by the imaging apparatus and environmental sensors, by an "expert system" which is trained to analyze and evaluate crop conditions. The expert system controls the spatial and temporal lighting pattern within the contained area, and the timing and allocation of nutrients and chemicals to achieve optimized crop development. A user can access the "expert system" remotely, to assess activity within the growth chamber, and can override the "expert system".

  18. Implementation of expert system in Prolog for infant seizures (United States)

    Gaweł, M.; Tataj, E.; Dunin-Wąsowicz, D.


    Expert Systems are found to be very promising as an important advisory tool. They can be useful in different situations where human expert is not available and decision should be undertaken quickly. Expert systems can also be useful in medicine to help doctors or even non-trained personnel (when the doctor is not available). These systems are important in clinical practice and could help in rapid finding of etiology and treatment. To fulfill such requirement in this contribution, we discuss an implementation of expert system, which is written in Prolog language. Since this language has its syntactical limitations, we have developed a general architecture of a shell type, to overcome these difficulties. Next, we have demonstrated its practical utility, by applying the knowledge taken from medical practice.

The author analyses practical difficulties of legal norm representation, creation of expert knowledge ontology, expert systems liability issues. Legal responsibility of expert system developers, users, and owners are also covered in this paper. Creation of legal ontologies is a complicated process because of the nature of the subject itself and the complexity and quantity of knowledge which must be represented in order to have fully functional legal expert system. Legal information basically consists of legal norms, doctrine, precedents and expert knowledge. All of these areas have specific representation issues, but the most difficult part is to make ontology and representation of expert knowledge. Different experts may have distinct points of view in some similar cases. Human decisions are made not only by applying certain rules to the problem decision pattern. Providence, analytical skills and critical thinking is required in legal professional work. Human reasoning and decision-making is not only based on symbolic values, it also consists of intermediate symbolic assumptions.

  3. Forms and Levels of Expertness: Interpreting Accounts of Typeface Design

    Directory of Open Access Journals (Sweden)

    Michael Harkins


    Full Text Available This article responds to problems arising from defining the notion of “expert” with respect to the subject of text typeface design. What and who is a type design expert? The author has identified that in both contemporary and historical contexts, paucity exists in relation to recorded knowledge regarding the processes of designing text typefaces. Accounts of knowledge of the practice of text typeface design differ in their perspectives relating to what may be deemed expertness. In attempting to explain or rationalize differences in perspectives of such accounts of practice, the problem of describing expertness arose. In terms of degrees of expertise relative to accounts of subject knowledge in text typeface design, the author developed the concept of “vicinage” in order to explore how we render expertness within research enquiry. This concept has the potential to focus future research in the area of defining expertise in typeface design and more generally beyond this field.

    Background Although there are various international consensus recommendations on the use of botulinum neurotoxin type A (BoNT/A) in facial aesthetics, there are no global or Russian guidelines on the optimal dose of incobotulinumtoxinA, free from complexing proteins, within specific aesthetic indications. This article reports the outcomes of two expert consensus meetings, conducted to review and analyze efficacy and tolerability data for incobotulinumtoxinA in various facial aesthetic indications and to give expert consensus recommendations to ensure best clinical practice among Russian clinicians. Methods Thirteen dermatology and/or plastic surgery experts attended meetings held in Paris, France (November 2013), and Moscow, Russia (March 2014). The expert group reviewed and analyzed the existing evidence, consensus recommendations, and Russian experts’ extensive practical experience of incobotulinumtoxinA in aesthetics to reach consensus on optimal doses, potential dose adjustments, and injection sites of incobotulinumtoxinA for facial aesthetics. Results All experts developed guidance on the optimal doses for incobotulinumtoxinA treatment of different regions of the upper and lower face. The expert panel agreed that there are no differences in the efficacy and duration of the effect between the four BoNT/As that are commercially available for facial aesthetic indications in Russia and that, when administered correctly, all BoNT/As can achieve optimal results. Experts also agreed that nonresponse to BoNT/A can be caused by neutralizing antibodies. Conclusion On the basis of the scientific and clinical evidence available for incobotulinumtoxinA, coupled with the extensive clinical experience of the consensus group, experts recommended the optimal doses of incobotulinumtoxinA effective for treatment of wrinkles of the upper and lower face to achieve the expected aesthetic outcome. These first Russian guidelines on the optimal use of incobotulinumtoxinA for

  8. Grounded theory in medical laboratory science expert practice development. (United States)

    Leibach, Elizabeth Kenimer


    Grounded theory and methods related to expert practice development in medical laboratory science were described using data from a large national survey of medical laboratory scientists (MLS) overlaid on findings from analysis of expert practice domains reported in nursing literature. An extensive focus group/expert review iterative process followed by a survey of MLS practitioners produced 25 critical thinking (CT) behaviors important in expert practice. Factor analysis was applied to discern common threads or themes linking the CT behaviors. The 25 important CT behaviors were reduced to a 7-factor structure representing constructs underlying the individual, observable CT behaviors. This 7-factor structure in MLS was compared to the 7 practice domains identified in expert nursing practice. The comparison yielded commonality between MLS and nursing in CT behaviors observed in the 7 expert practice domains of both professions: professional techniques, caring communication, growing professionally, setting priorities, practicing with judgment, anticipating/revising, and creating unique meaning. Emergent grounded theory is that (1) critical thinking is a metaprocess that facilitates learning by interlinking the more basic processes associated with different learning orientations: cognitivist, behaviorist, humanist (affective), and situated/contextual learning, (2) CT behaviors are observable events following from the CT metaprocess, and (3) observations of CT behaviors increase as practice advances from novice to expert. Identification and definition of CT behaviors, i.e., practice competencies, along the continuum of novice to expert can serve as the foundation for MLS curriculum and instructional design as well as measurement and evaluation in both formal and continuing education settings.

  12. Nephrology nursing: blurring the boundaries: the reality of expert practice. (United States)

    Bonner, Ann; Walker, Annette


    Expertise in nursing has been widely studied; there have been no previous studies into what constitute expertise in nephrology (renal) nursing. This paper describes a 'real-world' characteristic of expert nephrology nursing practice. This paper, which is abstracted from a larger study into the acquisition and exercise of nephrology nursing expertise, aims to explore the concept blurring the boundaries. The study utilized grounded theory methodology and symbolic interactionism. The study took place in one renal unit in New South Wales. Sampling was purposive then theoretical; the sample consisting of six non-expert and eleven expert nurses. Simultaneous data collection and analysis using participant observation, review of nursing documentation and semi-structured interviews was undertaken. The study revealed that only expert nephrology nurses 'blurred the boundaries' of professional nursing practice. They did this by moving intermittently and purposefully, for the benefit of particular patients, into medical domains in the areas of prescribing, dispensing and ordering of pathology tests. Non-expert nurses did not cross these professional boundaries. Blurring the boundaries was a significant feature of expert nursing practice, and this study was the first to describe explicitly nursing boundaries as two distinct entities; that is, formal and informal. There are some nephrology nurses who have sufficient knowledge and experience to prescribe some medications and to order certain investigations.

  13. ICADS: A cooperative decision making model with CLIPS experts (United States)

    Pohl, Jens; Myers, Leonard


    A cooperative decision making model is described which is comprised of six concurrently executing domain experts coordinated by a blackboard control expert. The focus application field is architectural design, and the domain experts represent consultants in the area of daylighting, noise control, structural support, cost estimating, space planning, and climate responsiveness. Both the domain experts and the blackboard were implemented as production systems, using an enhanced version of the basic CLIPS package. Acting in unison as an Expert Design Advisor, the domain and control experts react to the evolving design solution progressively developed by the user in a 2-D CAD drawing environment. A Geometry Interpreter maps each drawing action taken by the user to real world objects, such as spaces, walls, windows, and doors. These objects, endowed with geometric and nongeometric attributes, are stored as frames in a semantic network. Object descriptions are derived partly from the geometry of the drawing environment and partly from knowledge bases containing prototypical, generalized information about the building type and site conditions under consideration.

  14. A theory of expert leadership (TEL) in psychiatry. (United States)

    Goodall, Amanda H


    Leaders' technical competence - 'expert knowledge' - has been shown in many settings to be associated with better organizational performance. In universities, for example, there is longitudinal evidence that research-focused scholars make the best leaders; results from a hospital study show that doctors instead of professional managers are most closely associated with the best performing institutions. To explain these patterns, and raise hypotheses, a theory of expert leadership (TEL) has been developed that might explain these patterns. In this paper the framework for expert leadership is applied to psychiatry. The TEL proposes that psychiatric leaders, as opposed to non-expert managers, improve organizational performance through several channels. First, experts' knowledge influences organizational strategy. Second, having been 'one of them', a psychiatrist understands how to create the optimal work environment for psychiatric teams, through appropriate goal-setting, evaluation and support. These factors are positively associated with workers' wellbeing and performance. Third, exceptional psychiatrist-leaders are likely to set high standards for hiring. Fourth, leaders' credibility extends their influence among core workers, and also signals organizational priorities to stakeholders. Finally, a necessary prerequisite of TEL is that expert leaders have direct executive power inclusive of budgetary and strategic oversight. © The Royal Australian and New Zealand College of Psychiatrists 2015.

  15. Systematic methods for knowledge acquisition and expert system development (United States)

    Belkin, Brenda L.; Stengel, Robert F.


    Nine cooperating rule-based systems, collectively called AUTOCREW, were designed to automate functions and decisions associated with a combat aircraft's subsystem. The organization of tasks within each system is described; performance metrics were developed to evaluate the workload of each rule base, and to assess the cooperation between the rule-bases. Each AUTOCREW subsystem is composed of several expert systems that perform specific tasks. AUTOCREW's NAVIGATOR was analyzed in detail to understand the difficulties involved in designing the system and to identify tools and methodologies that ease development. The NAVIGATOR determines optimal navigation strategies from a set of available sensors. A Navigation Sensor Management (NSM) expert system was systematically designed from Kalman filter covariance data; four ground-based, a satellite-based, and two on-board INS-aiding sensors were modeled and simulated to aid an INS. The NSM Expert was developed using the Analysis of Variance (ANOVA) and the ID3 algorithm. Navigation strategy selection is based on an RSS position error decision metric, which is computed from the covariance data. Results show that the NSM Expert predicts position error correctly between 45 and 100 percent of the time for a specified navaid configuration and aircraft trajectory. The NSM Expert adapts to new situations, and provides reasonable estimates of hybrid performance. The systematic nature of the ANOVA/ID3 method makes it broadly applicable to expert system design when experimental or simulation data is available.

    Full Text Available Negative correlations between pupil size and the tendency to look at salient locations were found in recent studies (e.g., Mathôt et al., 2015. It is hypothesized that this negative correlation might be explained by the mental effort put by participants in the task that leads in return to pupil dilation. Here we present an exploratory study on the effect of expertise on eye-movement behavior. Because there is no available standard tool to evaluate WoW players’ expertise, we built an off-game questionnaire testing players’ knowledge about WoW and acquired skills through completed raids, highest rated battlegrounds, Skill Points, etc. Experts (N = 4 and novices (N = 4 in the massively multiplayer online role-playing game World of Warcraft (WoW viewed 24 designed video segments from the game that differ in regards with their content (i.e, informative locations and visual complexity (i.e, salient locations. Consistent with previous studies, we found a negative correlation between pupil size and the tendency to look at salient locations (experts, r =  − .17, p < .0001, and novices, r =  − .09, p < .0001. This correlation has been interpreted in terms of mental effort: People are inherently biased to look at salient locations (sharp corners, bright lights, etc., but are able (i.e., experts to overcome this bias if they invest sufficient mental effort. Crucially, we observed that this correlation was stronger for expert WoW players than novice players (Z =  − 3.3, p = .0011. This suggests that experts learned to improve control over eye-movement behavior by guiding their eyes towards informative, but potentially low-salient areas of the screen. These findings may contribute to our understanding of what makes an expert an expert.

  4. CRN5EXP: Expert system for statistical quality control (United States)

    Hentea, Mariana


    The purpose of the Expert System CRN5EXP is to assist in checking the quality of the coils at two very important mills: Hot Rolling and Cold Rolling in a steel plant. The system interprets the statistical quality control charts, diagnoses and predicts the quality of the steel. Measurements of process control variables are recorded in a database and sample statistics such as the mean and the range are computed and plotted on a control chart. The chart is analyzed through patterns using the C Language Integrated Production System (CLIPS) and a forward chaining technique to reach a conclusion about the causes of defects and to take management measures for the improvement of the quality control techniques. The Expert System combines the certainty factors associated with the process control variables to predict the quality of the steel. The paper presents the approach to extract data from the database, the reason to combine certainty factors, the architecture and the use of the Expert System. However, the interpretation of control charts patterns requires the human expert's knowledge and lends to Expert Systems rules.

  5. The neural organization of perception in chess experts. (United States)

    Krawczyk, Daniel C; Boggan, Amy L; McClelland, M Michelle; Bartlett, James C


    The human visual system responds to expertise, and it has been suggested that regions that process faces also process other objects of expertise including chess boards by experts. We tested whether chess and face processing overlap in brain activity using fMRI. Chess experts and novices exhibited face selective areas, but these regions showed no selectivity to chess configurations relative to other stimuli. We next compared neural responses to chess and to scrambled chess displays to isolate areas relevant to expertise. Areas within the posterior cingulate, orbitofrontal cortex, and right temporal cortex were active in this comparison in experts over novices. We also compared chess and face responses within the posterior cingulate and found this area responsive to chess only in experts. These findings indicate that the configurations in chess are not strongly processed by face-selective regions that are selective for faces in individuals who have expertise in both domains. Further, the area most consistently involved in chess did not show overlap with faces. Overall, these results suggest that expert visual processing may be similar at the level of recognition, but need not show the same neural correlates. Copyright © 2011 Elsevier Ireland Ltd.

  6. Judgments of physics problem difficulty among experts and novices (United States)

    Fakcharoenphol, Witat; Morphew, Jason W.; Mestre, José P.


    Students' ability to effectively study for an exam, or to manage their time during an exam, is related to their metacognitive capacity. Prior research has demonstrated the effective use of metacognitive strategies during learning and retrieval is related to content expertise. Students also make judgments of their own learning and of problem difficulty to guide their studying. This study extends prior research by investigating the accuracy of novices' and experts' ability to judge problem difficulty across two experiments; here "accuracy" refers to whether or not their judgments of problem difficulty corresponds with actual exam performance in an introductory mechanics physics course. In the first experiment, physics education research (PER) experts judged the difficulty of introductory physics problems and provided the rationales behind their judgments. Findings indicate that experts use a number of different problem features to make predictions of problem difficulty. While experts are relatively accurate in judging problem difficulty, their content expertise may interfere with their ability to predict student performance on some question types. In the second experiment novices and "near experts" (graduate TAs) judged which question from a problem pair (taken from a real exam) was more difficult. The results indicate that judgments of problem difficulty are more accurate for those with greater content expertise, suggesting that the ability to predict problem difficulty is a trait of expertise which develops with experience.

  7. The paradox of expert judgment in rivers ecological monitoring. (United States)

    Feio, M J; Calapez, A R; Elias, C L; Cortes, R M V; Graça, M A S; Pinto, P; Almeida, S F P


    A great investment has been done in the last decades in the development of numerical and qualitative assessment methods to classify the ecological quality of water bodies. Yet, in spite of all attempts to avoid subjectivity, expert judgment is still used at numerous steps of the ecological classification and is considered by some authors as indispensible for management purposes. Thus, the aim of this study is to test the hypothesis that expert judgment, when done by the adequate experts (limnologists/river ecologist) with experience in the study area (i.e., natural conditions and expected communities), could be as good as quantitative indices and measures (i.e., result in the same classification), but quicker and with lower cost. For that we compared the classifications (on 13 aspects of rivers ecosystems) attributed by two experts to 20 sites (10 each) located in their study areas, with the classifications of ecological quality based on biological indices (for invertebrates and diatoms), hydromorphology and water chemistry, calculated by an independent team. Our results show that assessments made by experts and those calculated through indices (biological quality and hydromorphology) are globally very similar (RELATE test; Rho = 0.442; p ecological quality, saving money and time and helping to redirect monitoring funds to actual implementation of restoration measures.

    Full Text Available The paper describes the development of a prototype web-based expert knowledge system that can be used to maintain flexible pavement within a tropical region. This prototype system provides the advantages of using existing web-based expert system technology. Currently, deterioration of asphalt pavement layers is one of the biggest problems in Malaysia and requires maintenance to ensure that the roads remain open and able to guarantee the regularity, punctuality, and safety of all transport services. According to this process, the knowledge collection that has acquired and the date concerning to domain expert system of the development web-based system was launched with knowledge representation IF and THEN rules and coded by PHP programming. The web pages that support the user interface are created using a framework consisting of HTML, CSS, and J-Query. The prototype web-based expert system uses the knowledge of a pavement maintenance expert, or a specialist in pavement problem remediation, to emulate a portion of their professional reasoning abilities, which it can then use to assist with the maintenance of existing roads and enhance the efficiency and accuracy of the professional engineers tasked with the assessment of all available remedies. Thus, the system increases the performance level of the engineers in analysing, discerning and customising the information that will assist decision makers throughout the project, so the probability that the right decision and treatment are implemented at the right time is increased.

  9. Expert system for skin problem consultation in Thai traditional medicine. (United States)

    Nopparatkiat, Pornchai; na Nagara, Byaporn; Chansa-ngavej, Chuvej


    This paper aimed to demonstrate the research and development of a rule-based expert system for skin problem consulting in the areas of acne, melasma, freckle, wrinkle, and uneven skin tone, with recommended treatments from Thai traditional medicine knowledge. The tool selected for developing the expert system is a software program written in the PHP language. MySQL database is used to work together with PHP for building database of the expert system. The system is web-based and can be reached from anywhere with Internet access. The developed expert system gave recommendations on the skin problem treatment with Thai herbal recipes and Thai herbal cosmetics based on 416 rules derived from primary and secondary sources. The system had been tested by 50 users consisting of dermatologists, Thai traditional medicine doctors, and general users. The developed system was considered good for learning and consultation. The present work showed how such a scattered body of traditional knowledge as Thai traditional medicine and herbal recipes could be collected, organised and made accessible to users and interested parties. The expert system developed herein should contribute in a meaningful way towards preserving the knowledge and helping promote the use of Thai traditional medicine as a practical alternative medicine for the treatment of illnesses.

  10. Defining Expertise in Gynecologic Surgery: Perspectives of Expert Gynecologic Surgeons. (United States)

    Hardré, Patricia L; Nihira, Mikio; LeClaire, Edgar; Moen, Michael

    The aim of this study was to describe how professional expertise is defined and understood among gynecologic surgeons and what experiential factors contribute to that understanding. Semistructured interviews with 16 experts in Female Pelvic Medicine and Reconstructive Surgery were conducted to identify how expertise in their field is defined, recognized, and assessed. Independent thematic analysis of the interview transcripts was performed by each member of the research team and then distilled and synthesized into convergent themes. Experts described surgical expertise as difficult to define but with several dominant themes including knowledge, technical skills, clinical experience, adaptability, continuous learning, communication, and professional recognition. Expertise requires judgment in applying technical skills to meet each patient's specific needs. Experts described unique ways of seeing and thinking during surgery, characterized by spatial awareness of relevant anatomy, temporal awareness of future changes, and rapidly adaptive application of their skills enabling them to do difficult tasks with fluidity, making the tasks seem easy to observers. These expert surgeons acknowledged that achieving expertise requires hard work and maintaining expertise requires continuous learning, highlighted by challenge seeking to do the most difficult tasks in their field. They also noted the importance of effective communication of their knowledge to others, which contributes to their perception as experts by colleagues in the field. Surgical expertise is a complex phenomenon with several meaningful themes. Understanding the authentic nature of surgical expertise can be used to support the development of competencies and the effective mentoring of promising surgical trainees to achieve surgical expertise.

    Full Text Available Modification of attitude to labor in the society, in professional communities and among people is necessary for further development of society and national economy. This goal may be achieved if the system of professional training is modified: switched to competence approach which should include training of experts, including those in radiation hygiene, with a set of general cultural and professional competences. The system of future experts training should be based on traditions of domestic and international education; it should use modern forms of active and interactive education (computer simulations, business games and role-playing, analysis of concrete situations, portfolio, psychological and other trainings, remote education, etc. It should consider actuality of knowledge and skills and develop independence and responsibility that will enable the young expert to be competitive at the modern labor market and to meet employers’ expectations. Under the new federal educational standard on radiation hygiene accepted in 2014 at present primary specialization in radiation hygiene takes place in internship. At training of experts the new standard provides great use of on-the-job training, independent work, scientific and practical work. Employers should play an important role in training of experts.

  12. Football experts versus sports economists: Whose forecasts are better? (United States)

    Frick, Bernd; Wicker, Pamela


    Given the uncertainty of outcome in sport, predicting the outcome of sporting contests is a major topic in sport sciences. This study examines the accuracy of expert predictions in the German Bundesliga and compares their predictions to those of sports economists. Prior to the start of each season, a set of distinguished experts (head coaches and players) express their subjective evaluations of the teams in school grades. While experts may be driven by irrational sentiments and may therefore systematically over- or underestimate specific teams, sports economists use observable characteristics to predict season outcomes. The latter typically use team wage bills given the positive pay-performance relationship as well as other factors (average team age, tenure, appearances on national team, and attendance). Using data from 15 consecutive Bundesliga seasons, the predictive accuracy of expert evaluations and sports economists is analysed. The results of separate estimations show that relative grade and relative wage bill significantly affect relative points, while age, tenure, appearances, and attendance are insignificant. In a joint model, relative grade and relative wage bill are still statistically significant, suggesting that the two types of predictions are complements rather than substitutes. Consequently, football experts and sports economists seem to rely on completely different sources of information when making their predictions.

  13. Capturing expert uncertainty in spatial cumulative impact assessments. (United States)

    Jones, Alice R; Doubleday, Zoë A; Prowse, Thomas A A; Wiltshire, Kathryn H; Deveney, Marty R; Ward, Tim; Scrivens, Sally L; Cassey, Phillip; O'Connell, Laura G; Gillanders, Bronwyn M


    Understanding the spatial distribution of human impacts on marine environments is necessary for maintaining healthy ecosystems and supporting 'blue economies'. Realistic assessments of impact must consider the cumulative impacts of multiple, coincident threats and the differing vulnerabilities of ecosystems to these threats. Expert knowledge is often used to assess impact in marine ecosystems because empirical data are lacking; however, this introduces uncertainty into the results. As part of a spatial cumulative impact assessment for Spencer Gulf, South Australia, we asked experts to estimate score ranges (best-case, most-likely and worst-case), which accounted for their uncertainty about the effect of 32 threats on eight ecosystems. Expert scores were combined with data on the spatial pattern and intensity of threats to generate cumulative impact maps based on each of the three scoring scenarios, as well as simulations and maps of uncertainty. We compared our method, which explicitly accounts for the experts' knowledge-based uncertainty, with other approaches and found that it provides smaller uncertainty bounds, leading to more constrained assessment results. Collecting these additional data on experts' knowledge-based uncertainty provides transparency and simplifies interpretation of the outputs from spatial cumulative impact assessments, facilitating their application for sustainable resource management and conservation.

  14. Expert elicitation survey on future wind energy costs (United States)

    Wiser, Ryan; Jenni, Karen; Seel, Joachim; Baker, Erin; Hand, Maureen; Lantz, Eric; Smith, Aaron


    Wind energy supply has grown rapidly over the last decade. However, the long-term contribution of wind to future energy supply, and the degree to which policy support is necessary to motivate higher levels of deployment, depends—in part—on the future costs of both onshore and offshore wind. Here, we summarize the results of an expert elicitation survey of 163 of the world’s foremost wind experts, aimed at better understanding future costs and technology advancement possibilities. Results suggest significant opportunities for cost reductions, but also underlying uncertainties. Under the median scenario, experts anticipate 24-30% reductions by 2030 and 35-41% reductions by 2050 across the three wind applications studied. Costs could be even lower: experts predict a 10% chance that reductions will be more than 40% by 2030 and more than 50% by 2050. Insights gained through expert elicitation complement other tools for evaluating cost-reduction potential, and help inform policy and planning, R&D and industry strategy.

  16. Expert judgment and uncertainty regarding the protection of imperiled species. (United States)

    Heeren, Alexander; Karns, Gabriel; Bruskotter, Jeremy; Toman, Eric; Wilson, Robyn; Szarek, Harmony


    Decisions concerning the appropriate listing status of species under the U.S. Endangered Species Act (ESA) can be controversial even among conservationists. These decisions may determine whether a species persists in the near term and have long-lasting social and political ramifications. Given the ESA's mandate that such decisions be based on the best available science, it is important to examine what factors contribute to experts' judgments concerning the listing of species. We examined how a variety of factors (such as risk perception, value orientations, and norms) influenced experts' judgments concerning the appropriate listing status of the grizzly bear (Ursus arctos horribilis) population in the Greater Yellowstone Ecosystem. Experts were invited to complete an online survey examining their perceptions of the threats grizzly bears face and their listing recommendation. Although experts' assessments of the threats to this species were strongly correlated with their recommendations for listing status, this relationship did not exist when other cognitive factors were included in the model. Specifically, values related to human use of wildlife and norms (i.e., a respondent's expectation of peers' assessments) were most influential in listing status recommendations. These results suggest that experts' decisions about listing, like all human decisions, are subject to the use of heuristics (i.e., decision shortcuts). An understanding of how heuristics and related biases affect decisions under uncertainty can help inform decision making about threatened and endangered species and may be useful in designing effective processes for protection of imperiled species. © 2016 Society for Conservation Biology.

  17. NIOSH testimony on polychlorinated biphenyls before the Subcommittee on Oversight and Investigations, House Committee on Interstate and Foreign Commerce, by A. Robbins, March 12, 1980

    Energy Technology Data Exchange (ETDEWEB)


    The testimony concerned the efforts of NIOSH in a study of worker exposure to polychlorinated biphenyls (PCBs) at selected General Services Administration (GSA) facilities in the area of metropolitan Washington. The GSA employees being studied were exposed to transformer fluids containing PCBs in the National Capital Region. NIOSH was to review work practices, recommend appropriate PCB handling procedures, and measure airborne levels of PCBs and certain other chemicals. An internal audit at the site had revealed that the PCB material was being improperly stored at the Switch Gear Shop; 43 employees reported various health problems such as sterility, headaches, nausea, skin rashes and loss of appetite. The health of these 43 workers will be compared with a comparison group of unexposed GSA employees. The workers will be given complete medical examinations, including special tests to determine if they suffer from infertility, liver damage, nerve damage, or impairment of lung function.

  18. Beyond K's Specter: Chang-rae Lee’s A Gesture Life, Comfort Women Testimonies, and Asian American Transnational Aesthetics

    Directory of Open Access Journals (Sweden)

    Belinda Kong


    Full Text Available

    This essay argues that Chang-rae Lee’s novel A Gesture Life exemplifies both the conceptual gains and the potential pitfalls of current Asian American literature’s transnationalism. The first section of the essay discusses the interlocking of psychoanalytic theory and political philosophy, specifically Freud’s uncanny and Arendt’s banality of evil, in Lee’s portrait of the psychology of criminal repression. The second section juxtaposes Lee’s novel against real-life comfort women’s survivor testimonies to probe broader questions of historical memory, politicized historiography, and the modes of circulation and authority in contemporary international comfort women discourse. The final section, which recontextualizes Lee’s novel within current debates in Asian and Asian American Studies, argues against a paradigm of alterity vis-à-vis the comfort women and proposes instead a transnational aesthetic premised on the human.

  20. Risk taking in adversarial situations: Civilization differences in chess experts. (United States)

    Chassy, Philippe; Gobet, Fernand


    The projections of experts in politics predict that a new world order will emerge within two decades. Being multipolar, this world will inevitably lead to frictions where civilizations and states will have to decide whether to risk conflict. Very often these decisions are informed if not taken by experts. To estimate risk-taking across civilizations, we examined strategies used in 667,599 chess games played over eleven years by chess experts from 11 different civilizations. We show that some civilizations are more inclined to settle for peace. Similarly, we show that once engaged in the battle, the level of risk taking varies significantly across civilizations, the boldest civilization using the riskiest strategy about 35% more than the most conservative civilization. We discuss which psychological factors might underpin these civilizational differences. Copyright © 2015. Published by Elsevier B.V.

  1. Applying expert systems technology to communications software validation (United States)

    Davis, Margaret J.

    This case study describes the use of an expert-systems approach to automation of systems and integration testing for validation of complex, real-time communications software, such as used onboard the Airborne Warning and Control Systems (AWACS) aircraft. The approach permits a state-based rather than path- or branch-based testing style. States can be matched with high-level system requirements to give a measure of test coverage. The benefits and weaknesses realized from using the Boeing-built embeddable expert systems shell with a custom relational database interface to construct an automated software verification tool supporting this approach are discussed, along with a brief summary of the utility of applying expert systems technology in this software engineering area. Qualitative measurements of the productivity increase from a prototype demonstration are also included.

    Full Text Available Paper presents a methodology for design of integrated fuzzy logic based an expert controller and its implementation for a real time oven temperature control system. Integrated expert controller (IEC is composed by cascading fuzzy logic controller with improved PID controller. Wherein, fuzzy controller evaluates the supplemental control actions and PID evaluates the final control actions. Temperature measurement of the oven with a precision of 16-bits is achieved through Pt100, instrumentation amplifier, and A/D converter and fuzzy plus PID computed control actions are given to the actuator via D/A converter (16-bits and PWM generator. Paper experimentally demonstrated the performance of IEC for oven temperature control application. The performance indexes of the system are presented in a comparative fashion with the conventional PID and expert controllers. Control algorithms are developed using C language.

  3. Knowledge acquisition for expert systems using statistical methods (United States)

    Belkin, Brenda L.; Stengel, Robert F.


    A common problem in the design of expert systems is the definition of rules from data obtained in system operation or simulation. A statistical method for generating rule bases from numerical data, motivated by an example based on aircraft navigation with multiple sensors is presented. The specific objective is to design an expert system that selects a satisfactory suite of measurements from a dissimilar, redundant set, given an arbitrary navigation geometry and possible sensor failures. The systematic development of a Navigation Sensor Management (NSM) Expert System from Kalman Filter covariance data is described. The development method invokes two statistical techniques: Analysis-of-Variance (ANOVA) and the ID3 algorithm. The ANOVA technique indicates whether variations of problem parameters give statistically different covariance results, and the ID3 algorithm identifies the relationships between the problem parameters using probabilistic knowledge extracted from a simulation example set.

  4. ANAPPRES: An expert system for interference well-test analysis

    Energy Technology Data Exchange (ETDEWEB)

    Arellano, V.M.; Iglesias, E.R.; Arellano, J.; Schwarzblat, M.


    We present ANAPPRES V1.0, the first version of a computerized expert system capable of analyzing constant- and variable-flowrate interference tests, in which there is one active well and an arbitrary number of observation wells, in liquid-saturated homogeneous reservoirs. ANAPPRES successfully couples mathematical models, optimization techniques, heuristic knowledge and computerized graphics, a combination not often found in published expert systems. Its main advantages are that it is user friendly, requires essentially no experience on the part of the analyst, eliminates subjectivity associated with earlier techniques of analysis, can handle complex cases and large data sets, completes the analysis of even the most complex cases (including plotting the results) in one run, and is significantly faster than a human expert.

This editorial analyses the relevant evidentiary principles and the Australian jurisprudence on the subject, giving particular attention to the decisions of the South Australian Supreme Court in R v Parenzee [2007] SASC 143 and R v Parenzee [2007] SASC 316 in which expert opinions about the existence, identifiability and transmissibility of HIV and its relationship to AIDS adduced on behalf of the defence in a criminal trial were found to be seriously wanting. A variety of factors indicative of low probative value in expert opinions are distilled.

  6. Analyzing patterns in experts' approaches to solving experimental problems (United States)

    Čančula, Maja Poklinek; Planinšič, Gorazd; Etkina, Eugenia


    We report detailed observations of three pairs of expert scientists and a pair of advanced undergraduate students solving an experimental optics problem. Using a new method ("transition graphs") of visualizing sequences of logical steps, we were able to compare the groups and identify patterns that could not be found using previously existing methods. While the problem solving of undergraduates significantly differed from that of experts at the beginning of the process, it gradually became more similar to the expert problem solving. We mapped problem solving steps and their sequence to the elements of an approach to teaching and learning physics called Investigative Science Learning Environment (ISLE), and we speculate that the ISLE educational framework closely represents the actual work of physicists.

  9. Business aspects and sustainability for healthgrids - an expert survey. (United States)

    Scholz, Stefan; Semler, Sebastian C; Breitner, Michael H


    Grid computing initiatives in medicine and life sciences are under pressure to prove their sustainability. While some first business model frameworks were outlined, few practical experiences were considered. This gap has been narrowed by an international survey of 33 grid computing experts with biomedical and non-biomedical background on business aspects. The experts surveyed were cautiously optimistic about a sustainable implementation of grid computing within a mid term timeline. They identified marketable application areas, stated the underlying value proposition, outlined trends and specify critical success factors. From a general perspective of their answers, they provided a stable basis for a road map of sustainable grid computing solutions for medicine and life sciences.

  12. Risk Reduction with a Fuzzy Expert Exploration Tool

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, William W.; Broadhead, Ron; Mundorf, William R.


    A state-of-the-art exploration ''expert'' tool, relying on a computerized database and computer maps generated by neural networks, was developed through the use of ''fuzzy'' logic, a relatively new mathematical treatment of imprecise or non-explicit parameters and values. Oil prospecting risk can be reduced with the use of a properly developed and validated ''Fuzzy Expert Exploration (FEE) Tool.'' This FEE Tool can be beneficial in many regions of the U.S. by enabling risk reduction in oil and gas prospecting as well as decreased prospecting and development costs.

  13. An expert system for the calculation of sample size. (United States)

    Ebell, M H; Neale, A V; Hodgkins, B J


    Calculation of sample size is a useful technique for researchers who are designing a study, and for clinicians who wish to interpret research findings. The elements that must be specified to calculate the sample size include alpha, beta, Type I and Type II errors, 1- and 2-tail tests, confidence intervals, and confidence levels. A computer software program written by one of the authors (MHE), Sample Size Expert, facilitates sample size calculations. The program uses an expert system to help inexperienced users calculate sample sizes for analytic and descriptive studies. The software is available at no cost from the author or electronically via several on-line information services.

  14. A local area computer network expert system framework (United States)

    Dominy, Robert


    Over the past years an expert system called LANES designed to detect and isolate faults in the Goddard-wide Hybrid Local Area Computer Network (LACN) was developed. As a result, the need for developing a more generic LACN fault isolation expert system has become apparent. An object oriented approach was explored to create a set of generic classes, objects, rules, and methods that would be necessary to meet this need. The object classes provide a convenient mechanism for separating high level information from low level network specific information. This approach yeilds a framework which can be applied to different network configurations and be easily expanded to meet new needs.

    In the aging population of Germany the consequences of Dementia for the society and the health care sector are complex and solutions require a multidisciplinary approach. The aim of the two-day interdisciplinary expert conference was to consider dementia from different perspectives, to identify dementia-related problems and to discuss integrative solutions under consideration of complementary therapies. In different working groups the experts developed solutions and recommendations with regards to political need, health care and future research priorities. The present recommendations profited very much from the interdisciplinary participants of the conference and brought together the expertise of different fields resulting in a comprehensive picture about dementia in Germany.

  16. Electrophysiological correlates of aesthetic music processing: comparing experts with laypersons. (United States)

    Müller, Mira; Höfel, Lea; Brattico, Elvira; Jacobsen, Thomas


    We analyzed the processes of making aesthetic judgments of music, focusing on the differences between music experts and laypersons. Sixteen students of musicology and 16 control subjects (also students) judged the aesthetic value as well as the harmonic correctness of chord sequences. Event-related potential (ERP) data indicate differences between experts and laypersons in making aesthetic judgments at three different processing stages. Additionally, effects of expertise on ERP components that have previously been proven to be sensitive to musical training were replicated. The study thus provides insights into the effects of musical expertise on neural correlates of aesthetic music processing.
